Description

Swing arm connection structure of fitness equipment and fitness equipment having the same

Technical field

The present invention relates to the technical field of fitness equipment, and in particular to a swing arm connection structure for fitness equipment.

Background technique

At this stage, with the improvement of people's living standards and the promotion of national fitness, people's pursuit of healthy life is also increasing, and fitness has become an indispensable part of people's daily life. In addition, with the change in fitness concepts, more and more people are going to the gym to exercise using specialized fitness equipment.

In the gym, you usually need to use special fitness equipment for the parts of the body you want to exercise and the items you want to exercise, such as Smith machines, seated rowing machines, inverted pedal machines, little flyes, T-shaped pull-down machines, and barbell training. These fitness equipment usually need to occupy a large area of use, which is not a burden for large gyms, but it is difficult to enter ordinary homes. In addition, due to professional reasons, these fitness equipment can usually only meet the training of a single movement. Even if the training of some movement items can be integrated into the same equipment, it is difficult to reduce the floor space of the equipment.

In this regard, in order to cater to ordinary families, a variety of new smart fitness equipment have appeared on the market at this stage. These smart fitness equipment generally replace traditional physical weights such as barbells with digitally controllable resistance methods such as resistance/wind resistance/electromagnetic resistance, and integrate handles/ropes/rope fixing devices/rope exit locking devices and other traditional equipment fields. The integrated design of each unit is replaced by a swing arm that can move freely in multiple directions. It achieves multiple functions in one machine with a compact structure and meets people's regular training projects. For example, for equipment such as small flying birds or gantry frames that are commonly used in regular fitness processes, traditional equipment also needs to be equipped with multiple weights of specific weights in order to pull weights with both hands or one hand to achieve specific training needs. Weights, and new smart fitness equipment can replace weights with resistance/wind resistance/electromagnetic resistance, etc., thereby reducing the size of the equipment. This makes it possible for dedicated fitness equipment to be integrated into ordinary homes.

For example, US Patent No. 2021038937 (A1) discloses a fitness equipment that can be placed vertically on a horizontal ground, uses a motor as a resistance source, and is provided with two swing arms on both sides. The two swing arms can along the vertical direction perpendicular to the ground By moving up and down, users can use the handle at the front of the swing arm to perform exercises.

Contents of the invention

The problem to be solved by the invention

However, the fitness equipment in Patent Document 1 is too highly integrated, resulting in excessively high costs, and the high degree of integration makes its manufacturing too difficult. In addition, even if the existing fitness equipment integrates some structures, it is still suitable for users in professional gyms. The size is still too large and is still not suitable for placement in ordinary family homes. Therefore, for ordinary family residences, the existing fitness equipment still has the problem of excessively large floor space. In particular, as mentioned above, fitness equipment has swing arms used for exercise by bodybuilders. However, in order to meet the needs of exercise, the swing arms usually need to have a certain length. However, the swing arms of existing fitness equipment are generally longer. , even if the fitness equipment is barely put into an ordinary family as a whole, it will occupy too much residential space, so it is not suitable for ordinary families.

In addition, when using fitness equipment, according to various exercise programs, additional space needs to be prepared for the swing arm to swing up, down, left, and right. In order to meet the swing arm swing space, the fitness equipment needs to have a higher height or be placed on a higher location, therefore, such a setting is still not suitable for being placed in the space of ordinary residences. Even for some small residences, it is simply impossible to put such equipment into them, hindering the popularity of fitness equipment.

In addition, swing arms are usually provided on both sides of the exterior of fitness equipment. When the fitness equipment is not in use, the swing arms and other components provided on the outside of the fitness equipment cannot be stored and hidden, so even if such fitness equipment can barely be placed in an ordinary In the family room, it also looks uncoordinated due to the exposure of the swing arm and other parts. It will also affect the aesthetics of the entire fitness equipment and even the room where the fitness equipment is stored. In particular, the utilization rate of home fitness equipment is not as high as that of gyms. When fitness equipment is not needed, it needs to be placed in a place that does not hinder the overall environment of the home. However, ordinary families cannot store it, even if they can barely store it. There is also the problem of wasting space and being unsightly.

In addition, if the swing arm of the fitness equipment in the prior art is too long, the torque at the joint of the swing arm (such as the joint) will be too large, resulting in damage to the fitness equipment.

To this end, the object of the present invention is to provide a swing arm connection structure of fitness equipment and fitness equipment having such a swing arm connection structure, which is suitable for use in rooms of ordinary homes and can reduce manufacturing processes and costs. , and can suppress the problem of excessive joint torque caused by too long swing arms, and has a compact structure that can be stored in a small volume when not in use, reducing the space occupied in the family home, and also making the appearance more beautiful. .

Invention effect

According to the present invention, because the slider can slide along the guide rail, when the two sliders are located at the top position of the front panel, the two are in a close state, and the two sliders move toward the front panel. The bottom slides away and gradually separates. Therefore, when the two slide blocks are at the top position, the two slide blocks and the swing arm connected to the slide blocks can be completely stored in the back area of the fitness equipment.

Therefore, when the swing arm of the fitness equipment is in the stowed state and the user of the fitness equipment faces the front panel and looks at it, the swing arm and the slider are blocked by the front panel, and the swing arm cannot be seen at all. The swing arm is hidden on the front panel. behind. As a result, the swing arm connection structure can be completely hidden by simply using the front panel, making the design of the fitness equipment more integrated, more beautiful, and suitable for home use.

In addition, when the fitness equipment is idle, because the swing arm connection structure at this time does not protrude to the side and is completely hidden, the height of the fitness equipment can be reduced, so the packaging size of the whole machine is smaller and the weight of the whole machine is lower, which makes transportation and installation easier. Easier. The device is smaller in size, saves space and looks more beautiful. When the swing arm is folded, no other components other than the front panel can even be seen at all. Especially when the front panel uses a mirror display, the idle part of the swing arm is stored The fitness equipment can be used as a mirror or display screen.

In addition, when you want to use fitness equipment for exercise, you only need to slide the slider downward so that the slider is gradually exposed from the storage area behind the front panel to the side, and the swing arm can also be moved from the storage area behind the front panel. Exposed to the side so that it is in the working position. This makes it easier to use.

In addition, by providing multiple engagement holes on the guide rail and multiple engagement pins on the slider, the slider can be positioned at multiple locations on the guide rail according to actual usage conditions, and can be used in pendulum applications according to various needs. Strength training with arms at different heights enables a variety of exercises to be performed with just one fitness equipment, which is easy to use.

In addition, in order to facilitate users to perform training actions such as squats, deadlifts, and high back pulls, the position of the rope needs to be a specified distance from the surrounding wall so that when the rope is pulled out corresponding to the training item, the end of the rope will not be disturbed , especially in the low and high positions, strength training requires the outlet end of the rope to cover a larger "outlet range". In this regard, in the present invention, since the swing arm can adjust the height position up and down as the slider slides, the fitness equipment can be hung on the wall for use. At this time, because the fitness equipment is hung on the wall at a certain distance from the ground and the base end position of the swing arm can be adjusted up and down with the slider, the swing arm can more easily meet the "outlet end range". As a result, the length of the swing arm can be made shorter, so that the torque endured by the connection will be smaller.

In summary, according to the present invention, a wide range of fitness equipment can be realized on small-sized fitness equipment. The coverage at the end of the swing arm can also suppress excessive joint torque caused by excessive length of the swing arm, reduce the space occupied by the home, and make the appearance more beautiful.

In addition, as shown in Figure 7, in a preferred embodiment of the present invention, when the user faces the fitness equipment F, it is preferred that the front panel 2 of the fitness equipment F is centrally symmetrical with the center line L as the symmetry line, and the above-mentioned The two swing arm connection structures are arranged symmetrically on the left and right sides of the fitness equipment F relative to the center line L.

In addition, for the convenience of explanation, in the present invention, the fitness equipment F in the state shown in FIGS. 1 to 4 is taken as an example, and the side of the fitness equipment F (front panel 2) facing the user is called "front or side". "Front" (the side facing the reader in Figure 1, the right side in Figure 2), and the side opposite to the "front" is called the "back or reverse side" (the side opposite to the side where the front panel 2 is located in Figure 2, That is the left side in Figure 2). In addition, the left hand side when the user faces the fitness equipment F is called the "left side" (the left side in the front view of FIG. 1 and the right side in the rear view of FIG. 3 ). The right-hand side is called the "right side" (the right side in the front view of Figure 1 and the left side in the rear view of Figure 3). In addition, in the state shown in FIG. 1 , the up-and-down direction may be called the "height direction of the fitness equipment" and the left-right direction may be called the "width direction of the fitness equipment." In the state shown in FIG. 2 , the left-right direction may be called "the thickness direction of the fitness equipment" or "the depth direction of the fitness equipment" or "the front-rear direction of the fitness equipment." In the present invention, these descriptions about direction and orientation are only set for the convenience of explaining the relative positional relationship between the components of the fitness equipment F of the present invention. If the posture of the fitness equipment F changes, the orientation The terminology has of course changed accordingly.

In addition, as shown in FIGS. 31 to 34 , a power source as a resistance source (in the present invention, for example, the motor 6 is used as an example) and a winding around which the rope R is wound are usually provided inside the main body 1 Disk 7, a resistance transmission mechanism of the winding disk 7 that can transmit the resistance generated by the motor 6 as a source of resistance, etc. As shown in the figure, the rope R on the reel 7 is passed through the inside of the swing arm unit 4 through the index of the pulley or pulley group inside the main body 1 and passes out from the swing arm unit 4 and is connected with the swing arm unit. The exercise unit at the front end of 4 is connected to, for example, a grip portion or a handle portion for the user to hold. In one example, the reel 7 is installed on the motor 6. When the motor 6 rotates, the reel 7 also rotates. When the rotation direction of the motor 6 is a direction in which the rope R can be wound, the rope R can be wound. A winding force is applied to the winding reel 7. In addition, when an external force pulls the rope R, a pulling force is applied to the rope R to be pulled out from the reel 7. Therefore, the user of the fitness equipment F For example, by holding the handle and pulling the rope R, the resistance generated by the motor 6 as a resistance source can be felt, thereby achieving various strength training and regular exercises. Of course, the motor 6 can also rotate in the opposite direction to the above-mentioned rotation direction. At this time, if the rope R is not subject to other external forces, the rope R is in a state of being hung loosely on the reel 7 .

Here, as a specific example of transmitting the resistance generated by the motor 6 as the resistance source via the rope R, for example, as shown in FIG. 32 , the bobbin 7 is attached to the motor 6 and the rope wound around the bobbin 7 After R passes through the first fixed pulley d1 inside the main body 1, the direction of the rope R becomes upward along the side of the main body 1, and then passes through the second fixed pulley d2 located at the top of the main body 1 to be adjusted to Downward along the length direction of the guide rail unit 5, and then through the third fixed pulley d3 of the slider unit 3 and the fourth fixed pulley d4 of the swing arm unit 4, and enters the swing arm unit 4, where the third fixed pulley d3 The rope R between the fourth fixed pulley d4 and the rotation axis of the swing arm unit 4 (the swing arm unit 4 rotates up and down around the slider unit 3 with the slider unit 3 as the center in Figure 10 The rotation axis) is coaxial to ensure that when the swing arm unit 4 rotates, the rope R is always coplanar and tangent to the third fixed pulley d3 and the fourth fixed pulley d4. In addition, the rope R between the second fixed pulley d2 and the third fixed pulley d3 is parallel to the guide rail 52 of the guide rail unit 5, ensuring that when the slider unit 3 moves on the guide rail unit 5, the rope R always remains in contact with the second fixed pulley d2 and the second fixed pulley d3. The third fixed pulley d3 is coplanar and tangent. Next, as shown in FIG. 32 , after the rope R passes through the fourth fixed pulley d4 of the swing arm unit 4 and enters the swing arm unit 4 , the rope R further passes through the wrist joint pulley d5 ( The figure shows two wrist joint pulleys d5, which sandwich the rope R) and Pass out the swing arm unit 4, and the end of the rope R after passing through the swing arm unit 4 is used as the rope outlet end (described later). At the front end of the swing arm unit 4, it can be connected with other unit components such as the grip part or the handle part as needed. or other unit connections. Therefore, when the motor 6 is running and the rotation direction is a direction in which the rope R can be wound, the winding force of the rope R is applied to the winding reel 7. When the user holds, for example, the handle and pulls the rope At R, an external force is exerted on the rope R to be pulled out from the reel 7 . At this time, the resistance exerted by the motor 6 remains opposite to the external force of the user pulling the rope R, and is transmitted to each other through the pulleys, so that strength training can be achieved. The above is only an example of preferred resistance transmission, but the present invention is not limited thereto. Other pulleys or pulley groups or other methods can also be used to transmit resistance. In addition, in the above description, only the resistance transmission situation of one side in FIG. 32 is taken as an example, and the description of the other side is omitted.

In addition, as the resistance transmission mechanism, a planetary differential gear, a bevel gear set, or any other mechanism that can transmit resistance can be used. There is no particular restriction on this, as long as the resistance generated by the motor 6 as the resistance source can be transmitted to the winding. Just plate 7. In addition, as shown in FIG. 34 (described later), the winding reel 7 may be directly attached to the motor 6 as the resistance source without providing a resistance transmission mechanism, and this is not particularly limited.

-Motor as a source of resistance or power-

In the present invention, for example, the inner rotor motor M shown in FIGS. 33 and 34 can be used as the motor 6 as the resistance source or the power source. Specifically, as shown in Figures 33 and 34, the inner rotor motor M mainly includes: a casing M1, a motor stator M2, and a motor rotor M3. The motor rotor M3 is disposed in the motor stator M2, and the motor rotor M3 has as Center shaft of rotor shaft M4. In addition, the above-mentioned winding disk 7 is also installed on the motor rotor M3. The housing M1 can accommodate the motor stator M2, the motor rotor M3 and the winding reel 7 inside.

Specifically, as shown in FIG. 34 , the winding disk 7 is laminated and fixed on the motor rotor M3 in a coaxial manner with the motor rotor M3 in the axial direction of the rotor shaft M4 , and the housing H disposes the motor stator M2 and the motor rotor M3 . The motor rotor M3 inside the motor stator M2 and the winding disk 7 coaxially stacked and fixed on the motor rotor M3 are housed inside. That is, the motor rotor M3, the rotor shaft M4, and the winding disk 7 are fixed together to form an integrated structure and can rotate about the central axis together, and are housed in the casing M1 together with the motor stator M2.

In addition, the housing M1 is formed of an upper end cap M5 and a lower end cap M6. Specifically, the upper end cap M5 and the lower end cap M6 are roughly cup-shaped (concave-shaped). By connecting the upper end cap M5 and the lower end cap M6 The covers M6 are fastened together to form the housing M1, thereby forming a storage space between the upper end cover M5 and the lower end cover M6. The motor stator M2, the motor rotor M3, the rotor shaft M4, the winding disk 7 and other components are all stored in this storage space.

In addition, the two ends of the rotor shaft M4 as the central axis are respectively fixed to the upper end cover M5 and the lower end cover M6 through bearings, and one end is also connected to an external resistance source, thereby functioning as a resistance input shaft.

In addition, the above-mentioned rope R is also wound around the reel 7, and the casing M1 is provided with a pull-out port (not shown) for the rope R, so that the rope R can be pulled out from the casing M1 to operate the resistance mechanism to perform exercise, etc. . Regarding the method of winding the rope R around the bobbin 7, for example, the bobbin 7 can be formed into a cylindrical shape and the rope R can be directly wound around its outer periphery. In addition, in order to prevent the rope R wound around the reel 7 from falling off, the reel 7 may be formed into a flange.

In addition, the above-mentioned inner rotor motor M is only an example of the motor 6 as the resistance source or power source of the present invention, but the present invention is not limited thereto, and various other types of motors can also be used. For example, an external rotor motor, a motor provided with a planetary gear transmission set, a motor provided with a bevel gear set, or a motor provided with other resistance transmission mechanisms may also be used. From the perspective of miniaturization and thinning of the fitness equipment F, it is preferable to use an inner-rotor motor and mount the winding disk directly on the motor and store it in the casing as shown in FIGS. 33 and 34 .

In addition, since the present invention mainly relates to the swing arm connection structure of fitness equipment, in the following description and drawings, the description of the motor 6, the coil reel 7, the rope R and other structures as the resistance source are sometimes omitted, and only the structure of the The details related to the swing arm connection structure will be explained in detail.

In addition, in the following description, the front panel 2 of the fitness equipment F is placed in a vertical state, and a swing arm connection structure (slider) is provided on the left and right sides of the fitness equipment F in a symmetrical manner with respect to the center line L. The case of unit 3, swing arm unit 4, and guide rail unit 5) will be described as an example.

-Front panel-

In the present invention, considering the cost of materials, the front panel 2 can be an ordinary plate such as an ordinary plastic plate or high-hardness plastic, but can also be a display panel and an operation panel (such as a liquid crystal display, a touch panel, etc.), or It is a structure in which a display screen and an operation screen are installed on the plate. Through this design, it is convenient for the user of the fitness equipment F to change the items he wants to exercise through the front panel 2, read and input fitness data, and control the exercise situation in real time. And the front panel 2 can also display fitness tutorial videos or play entertainment programs, etc. In addition, in addition to the above functions, the front panel 2 can also be made into a mirror or a mirror display device with a display operation function, so that users of the fitness equipment can observe their own exercise movements and operate them at any time. In addition, as shown in FIGS. 1 to 11 and 31 , when the swing arm unit 4 is in the stowed state, if the front panel 2 is made into a mirror or mirror display, the swing arm unit 4 (rear panel 2) cannot be seen. (described above), so the entire fitness equipment F is mirror-like in appearance and can be used as a mirror or a display device. Even when it is not powered on, it can also be used temporarily as a mirror such as a fitting mirror. This means that when the equipment is placed in an ordinary residence, it will not be out of tune with ordinary household equipment and will not damage the overall aesthetics of the room.

In addition, in the present invention, as shown in FIGS. 1 to 11 and 31 , the fact that the swing arm unit 4 of the fitness equipment F is in the stowed state means: as shown in the front view of FIG. 1 and the exploded view of FIG. 31 , The front length and width of the front panel 2 are larger than the front length and width of the main body 1 (the plane size of the front panel can basically cover the plane size of the main body). When the user of the fitness equipment F faces the front panel 2 and faces the fitness In equipment F, the swing arm unit 4 is blocked by the front panel 2 and cannot be seen. That is, the stored state refers to a state in which the swing arm unit 4 is hidden on the back surface of the front panel 2 . In addition, the swing arm unit 4 of the fitness equipment F is in a working state means that, as described later, the slider unit 3 slides along the guide rail unit 5 to a state where the exerciser can exercise through the swing arm unit 4, for example, as shown in Figure 5 The base ends of the slider unit 3 and the swing arm unit 4 are shown to be located at the lower end of the guide rail unit 5 (the bottom of the fitness equipment F), or the base ends of the slider unit 3 and the swing arm unit 4 are located as shown in Figure 10 The state of the guide rail unit 5 at its midway position. That is, the operating state refers to a state in which the arm swing unit 4 is exposed from the side of the fitness equipment F and the user can use the fitness equipment F by operating the arm swing unit 4 .

-First Embodiment-

Next, a specific embodiment of the swing arm connection structure of the present invention will be described in detail. Referring to Figures 1 to 11, in the present invention, the guide rail units 5 are arranged on the left and right sides of the main body 1 and extend linearly, with the extending direction being the up and down direction, and there is an included angle between the guide rail units 5 on the left and right sides. . In other words, the guide rail units 5 located on the left and right sides of the main body 1 are not parallel, and the two guide rail units 5 extend in a linear direction and intersect in the extending direction.

Here, the so-called "up and down direction" is not limited to the vertical up and down (vertical up and down) in the geometric sense, but also includes, for example, a slight inclination at a certain angle with respect to the vertical direction. in addition, As mentioned above, "arranging the guide rail units 5 on the left and right sides of the main body 1" is not limited to arranging the guide rail units 5 immediately adjacent to both sides of the main body 1, as long as the guide rail units 5 are located on the main body in terms of spatial position. Just the left and right sides of 1. For example, the guide rail unit 5 may be disposed on both sides of the main body 1 but at a certain distance from the left and right sides of the main body 1 as needed, or the guide rail unit 5 may be disposed in the thickness direction of the fitness equipment F. The positions on the left and right sides of the back of the main body 1 (for example, the front panel 2, the main body 1, and the guide rail unit 5 are stacked in order from the front to the back along the thickness direction of the fitness equipment F). That is, in the present invention, the specific installation position of the guide rail unit 5 is not limited, as long as there is an included angle between the guide rail units 5 on both sides. In addition, because the slider unit 3 slides on the guide rail unit 5, the extending direction of the guide rail unit 5 is actually the sliding direction when the slider unit 3 slides thereon.

Specifically, in a specific embodiment of the present invention, the main body 1 is roughly in the shape of an isosceles trapezoid (for example, refer to Figure 3 of the rear view or Figure 31 of the exploded view), and the guide rail units 5 are respectively along both sides of the main body 1 The sides (for example, the left and right sides of the main body 1 as the waist of the isosceles trapezoid in FIG. 3 ) are provided on both sides of the main body 1 . Therefore, in this specific embodiment, the extension direction of the guide rail unit 5 is actually substantially along the extension direction of the side of the isosceles trapezoidal main body part 1 . At this time, since the two sides of the main body 1 are used as the waist of the isosceles trapezoid, the two sides are formed to have an included angle relative to each other. Therefore, the guide rail units 5 provided on the left and right sides of the main body 1 also have an included angle. angle. In other words, the guide rail units 5 provided on both sides of the main body 1 are not parallel and tend to intersect in the extending direction.

In addition, here only to illustrate the installation of the guide rail unit 5, the case where the main body 1 is roughly isosceles trapezoidal and the guide rail units 5 are installed on both sides of the main body 1 is taken as an example. However, the present invention does not Limited to this, the main body 1 can be in any shape. For example, when the guide rail unit 5 is disposed on the side of the main body 1 , the main body 1 can also be in a triangular or other shape, as long as the main body 1 has two strips in the extending direction. Just go up the sides that are not parallel (intersecting). In addition, in the present invention, it is preferable that the two sides of the main body 1 are centrally symmetrical with respect to the center line L (for example, similar to the two waists of an isosceles trapezoid), so the specific shape of the main body is not specifically limited. From the perspective of stability and storageability of the fitness equipment, it is preferable that the main body 1 is roughly in the shape of an isosceles trapezoid as shown in FIG. 31 .

In addition, the guide rail units 5 do not have to be arranged along both sides of the main body 1 , as long as the two guide rail units 5 are not parallel in the extending direction. In addition, as mentioned above, for In "arrange the guide rail units 5 on both sides of the main body 1", it only suffices that the guide rail units 5 are located on both sides of the main body 1 in terms of spatial position. For example, the guide rail units 5 can also be disposed on the back of the main body 1. (the main body 1 and the guide rail unit 5 are arranged in sequence along the thickness direction of the fitness equipment F, so that the guide rail unit 5 is located on the back of the main body 1 and on both sides), this is not limited. However, from the viewpoint of reducing the thickness of the device and improving the sliding stability and safety between the slider unit 3 and the guide rail unit 5 , it is preferable to dispose the guide rail unit 5 next to the main body 1 in the width direction. The side of the main body 1.

-Second Embodiment-

Next, another specific embodiment of the swing arm connection structure of the present invention will be described in detail. In another specific embodiment, the front panel 2 is generally rectangular. For ease of explanation, as shown in Figures 1, 3 and 9, the four sides of the rectangular front panel 2 of this specific embodiment are named first. The side 21 (the left side in the front view of FIG. 1 and the right side in the rear view of FIG. 3), the second side (the right side in the front view of FIG. 1, FIG. The left side (side) 22, top edge 23, and bottom edge 24 in the rear view of 3. The two guide rail units 5 are located on the back side of the front panel 2. Same as the above-mentioned first embodiment, the two guide rail units 5 extend in the linear direction and intersect in the extension direction. That is, there is an included angle between the two guide rail units 5 on the left and right sides.

As shown in the figure, without considering the specific shape of the main body 1 , the included angle between the left and right guide rail units 5 means that, for example, the guide rail units 5 provided on the left and right sides of the main body 1 are relative to each other. The side edges of the front panel 2 on one side (the first side edge 21 and the second side edge 22 of the front panel 2 in FIGS. 1, 3, and 9) have a predetermined angle.

Specifically, the front panel 2 is substantially rectangular. As shown in FIG. 9 of a perspective view described later, the left guide rail unit 5 is not parallel to the left side (first side 21 ) of the front panel 2 but is opposite to the left side (first side 21 ) of the front panel 2 . The left side (first side 21 ) of the front panel 2 has a predetermined angle, and the right rail unit 5 is not parallel to the right side (second side 22 ) of the front panel 2 but is relative to the front panel 2 The right side (second side 22) of has a prescribed angle. In other words, the guide rail unit 5 on the left side and the guide rail unit 5 on the right side are not parallel but gradually move closer (a tendency to get closer) toward the top end (top edge 23 ) of the front panel 2 . Therefore, as shown in the rear view of FIG. 3 and the perspective view of FIG. 9 , the extending directions of the two guide rail units 5 are not parallel, and the extending directions of the two guide rail units 5 tend to cross as they go upwards of the main body 1 . (crossing in the extending direction), there is an included angle between the two guide rail units 5 . At this time, in the rear view of Figure 3 and the perspective view of Figures 7 to 9 In the view, the area enclosed by the two guide rail units 5 and the top edge 23 and the bottom edge 24 of the main body 1 is roughly an isosceles trapezoid, and the waist width becomes narrower as it goes upward (the extension direction of the two guide rail units 5 increases with the direction). The upper part of the main body 1 has a tendency to cross). Here, the so-called "intersection" or "intersection" means that the two guide rail units 5 have a tendency to intersect (for example, the extension lines of the guide rail units intersect in the extension direction), and does not specifically mean that there is an actual intersection.

Therefore, as shown in FIGS. 3 and 7 to 9 , in a plan view, on the back side of the fitness equipment F, the first side 21 (left side), the top side 23 and the left side of the front panel 2 The guide rail unit 5 defines a first storage area A, and a second storage area B is defined by the second side 22 (right side), the top side 23 of the front panel 2 and the guide rail unit 5 on the right side. It can be seen from the figure that because the extending directions of the two guide rail units 5 tend to cross as they go upwards of the main body 1, on the back side of the front panel 2, the first storage area A and the second storage area B cross The plane area of the storage area is larger closer to the top edge 23 of the front panel 2 (the upper part of the fitness equipment F).

At this time, as shown in Figures 3 and 9, because the slider unit 3 can slide along the guide rail unit 5, the extension directions of the left guide rail unit 5 and the right guide rail unit 5 intersect as they go upwards. trend, so when the two slider units 3 slide along the guide rail unit 5 to a position close to the top edge 23 of the front panel 2, the two slider units 3 are in a close state. At this time, the pendulum provided on the slider unit 3 The arm unit 4 is also in a close state. Therefore, when the two slider units 3 slide to a position close to the top edge 23 of the front panel 2, since the storage areas of the first storage area A and the second storage area B are larger here, the two slider units 3 can be The slider unit 3 is completely stored in the back area of the fitness equipment F, and the swing arm unit 4 connected to the slider unit 3 can also be stored in the corresponding storage area accordingly.

That is, when the two slider units 3 slide to a position close to the top edge 23 of the front panel 2 (storage state), when facing the fitness equipment F (front panel 2), the slider unit 3 and the swing arm unit 4 can be Covered by front panel 2. As a result, the user cannot see the slider unit 3 and the swing arm unit 4 stored in the first storage area A and the second storage area B when facing the front panel 2, so that the user can separate the slider unit 3 and the swing arm unit. 4 is hidden on the back of the front panel 2.

Therefore, when the slider unit 3 and the swing arm unit 4 of the fitness equipment F are in the stowed state, and the user of the fitness equipment F faces the front panel 2 to observe the fitness equipment F, both the swing arm unit 4 and the slider unit 3 are moved forward. It is blocked by the panel 2 , so the swing arm unit 4 cannot be seen at all, so that the swing arm unit 4 is hidden on the back of the front panel 2 .

Therefore, in the present invention, there is no need to install special components, and the swing arm unit 4 and the slider unit 3 can be completely stored in the fitness equipment F ( The storage area on the back of the front panel 2) can completely hide the swing arm connection structure in the storage state, which can make the design of the fitness equipment F more integrated. When the fitness equipment F is idle and in the storage state, it can The overall appearance is more beautiful, suitable for placement in ordinary homes, and will not be out of place with other furniture. In particular, when the fitness equipment F is idle, because the swing arm connection structure does not protrude to the side at all and is hidden behind the front panel 2, the appearance is neater and the body is smaller, thereby making the appearance more beautiful. On the front of the fitness equipment F, no other parts except the front panel 2 can be seen at all in the stored state. In particular, when the front panel 2 adopts a mirror display screen, when powered on, the fitness equipment F in the stored state can be used as an entertainment display device itself, and even when not powered on, it can also be used as an ordinary display device. Used as a mirror (such as a fitting mirror), it is not only small and compact overall, but also neat and beautiful in appearance, and can be easily placed and used anywhere in any home space. It will not be out of tune with other furniture and items in the family home, and it will not be incompatible with placement. There is no limit to the location of fitness equipment, which can save space and can be fully utilized even when it is idle. The layout and integrity of the room will not be destroyed by setting up fitness equipment F at home.

In addition, as shown in FIG. 9 , the left guide rail unit 5 and the right guide rail unit 5 gradually separate as they go toward the bottom edge 24 of the front panel 2 (the bottom of the fitness equipment F). Therefore, when you want to use the fitness equipment F for exercise, as shown in Figures 7 to 9, you only need to slide the slider unit 3 downward along the arrow direction so that the slider unit 3 slides downward along the guide rail unit 5. Then the slider unit 3 will move from a large area to a small area in the storage area on the back of the front panel 2 as the two guide rail units 5 are gradually separated (in FIGS. 7 to 9 , storage area A and storage area The upper part of the area B is a large area, and the area becomes smaller as you go down), and is gradually exposed from the side of the fitness equipment F, and the swing arm unit 4 connected to it is also moved from the storage area behind the front panel 2 to the side. Gradually exposed so that it is in working condition.

As an example, FIGS. 7 to 9 show a situation in which the slider unit 3 slides along the guide rail unit 5 to the lowermost end of the guide rail unit 5 (the lowermost end of the fitness equipment F). At this time, it can be applied to training movements such as squats and deadlifts, for example. In addition, as shown in Figure 10, the slider unit 3 can also be slid to the middle position of the guide rail unit 5 and fixed there to adapt to other Types of exercise programs, such as high pull-ups, tricep presses and other training actions. At this time, a plurality of engagement holes can be provided in the guide rail unit 5 and components such as engagement pins that can engage with the engagement holes can be provided in the slider unit 3 to fix it there, so that it can be fixed according to the actual use. The slider unit 3 is positioned at multiple locations on the guide rail unit 5 depending on the situation and exercise program. That is, the present invention can be applied to strength training with swing arms at different heights according to various needs, and can achieve various types of exercise with only one fitness equipment, which is easy to use.

-Connection method of swing arm unit and slider unit-

In the present invention, there is no limit to the way in which the swing arm unit 4 is connected to the slider unit 3. For example, a pivot connection structure or other connection methods may be used. Preferably, the swing arm unit 4 has an adjustable height relative to the slider unit 3 in the horizontal plane. The swing arm unit 4 can also be connected rotatably relative to the slider unit 3 in the horizontal plane according to the functional requirements of the fitness equipment. In addition, the swing arm unit 4 can also be connected to the slider unit 3 in a horizontal plane. Fixed connection, no special restrictions on this.

Referring to FIGS. 12 and 13 , a specific example of the connection between the swing arm unit 4 and the slider unit 3 will be briefly described. Figure 12 is an exploded view of an example of the connection between the swing arm unit 4 and the slider unit 3 in the swing arm connection structure of the fitness equipment F of the present invention. Figure 13 is an internal structure of the swing arm connection structure of the fitness equipment F of the present invention. A schematic diagram of an example, wherein FIG. 13 is a schematic diagram when viewed from above in the state shown in FIG. 1 .

As shown in FIGS. 12 and 13 , in one embodiment of the present invention, the slider unit 3 includes a slider 31 and a slider fixing base 32 that fixes the slider 31 thereon. The swing arm unit 4 includes a swing arm fixing base 41, a swing arm 42 provided on the swing arm fixing base 41, and an optical axis 43. The guide rail unit 5 includes a support base 51 and a guide rail 52 provided on the support base 51 . In addition, the slider 31 of the slider unit 3 can slide along the guide rail 52 of the guide rail unit 5 , so that the slider unit 3 including the slider 31 and the slider fixing base 32 fixed thereto can slide along the guide rail of the guide rail unit 5 . 52 slides.

In addition, as shown in Figure 13, the swing arm fixed seat 41 is connected to the slider fixed seat 32 via the optical axis 43. At this time, the optical axis 43 plays a role similar to a pivot. The swing arm unit 4 and the slider unit 3 are connected to each other. The overall structure is pivotally connected (hinged), so that the swing arm fixing seat 41 and the slider fixing seat 32 can have a tendency to pivot relative to each other. However, at this time, the swing arm fixing seat 41 and the slider fixing seat 32 are connected via The pivotal connection of the optical axis 43 does not necessarily require the two to rotate as long as there is a tendency to rotate (described later), but the optical axis 43 may also pivot. Additionally, as A specific way to pivotally connect the swing arm unit 4 and the slider unit 3, for example, as shown in Figure 12, Figure 13, Figure 16 and Figure 19, etc., can be to use the slider fixed seat 32 and the swing arm fixed seat respectively. 41. Set the shaft sleeve (or fixed hoop 47) and insert the optical shaft 43 into the shaft sleeve (or fixed hoop 47) to secure the swing arm fixed base through the combination of the optical shaft 43 and the shaft sleeve (or fixed hoop 47). 41 is connected to the slider fixing base 32. In addition, the optical axis 43 can also be installed and fixed by providing bearings on the swing arm fixing base 41 and/or the slider fixing base 32 to realize the connection between the swing arm fixing base 41 and the slider fixing base 32. The connection of the slider holder 32 is not particularly limited.

In addition, in an embodiment shown in FIG. 19 , the optical axis 43 is an independent component independent of the slider fixing base 32 and the swing arm fixing base 41 , but it is not limited to this, and the optical axis 43 can also be set to be fixed. The method of fixing the two by providing a sleeve or bearing on either the slider holder 32 or the swing arm holder 41 and inserting the optical axis 43 into it on the other side (Fig. 12 or Fig. 16) is as long as it can be realized The pivotal connection between the slider fixing base 32 and the swing arm fixing base 41 is not particularly limited.

In the present invention, it is preferable to provide sleeves/bearings/fixing hoops corresponding to both ends of the optical axis 43 on the slider holder 32 and the swing arm holder 41 respectively, and insert the optical axis into each sleeve/ The bearing/fixed hoop is used to connect the slider holder 32 and the swing arm holder 41. In addition, it is more preferable to fix the optical axis 43 to the swing arm fixing base 41 (for example, referring to FIG. 12 or FIG. 16 , the optical axis 43 and the swing arm fixing base 41 are integrated), and the two ends of the optical axis 43 are placed on the slider. The fixed seat 32 is provided with a bearing or a sleeve or a fixed hoop, and the optical axis 43 is inserted into the bearing, axle sleeve or a fixed hoop to realize the relative pivot connection between the slider fixed seat 32 and the swing arm fixed seat 41 .

In addition, by fixing the support base 51 of the guide rail unit 5 to the side surface of the main body 1, the entire guide rail unit 5 is attached to the side surface of the main body 1. In addition, there is a guide rail 52 fixed on the support seat 51 of the guide rail unit 5, so that the slider 31 of the slider unit 3 slides along the guide rail 52 of the guide rail unit 5, so that the entire slider unit 3 moves along the guide rail. 52 slides, and the swing arm unit 4 connected to the slider unit 3 also slides along the guide rail 52, thereby realizing the movement of the swing arm unit 4 and the slider unit 3 along the guide rail 52 in the substantially up and down direction. By sliding the swing arm unit 4 along the guide rail unit 5 (guide rail 52 ) in the substantially up and down direction, the position of the slider unit 3 in the height direction can be adjusted according to exercise items and different users, thereby adjusting the swing arm unit. The height of 4.

- Positioning and fixation of the slide unit relative to the guide rail unit and release of the fixation -

In the present invention, by providing components such as latch pins (engagement pins) and latch pin holes (engagement holes), when the slider unit 3 needs to be fixed relative to the guide rail unit 5, the insertion and combination of the latch pins and latch hole holes are used to fix the slider unit 3 to the guide rail unit 5. The block unit 3 is fixed at a predetermined position on the guide rail 52 of the guide rail unit 5 to achieve fixing (locking) of the slider unit 3 relative to the guide rail unit 5 . In addition, when it is necessary to release the fixation of the slider unit 3 relative to the guide rail unit 5 to realize the sliding of the slider unit 3, the positioning of the slider unit 3 and the guide rail unit 5 is released by relatively separating the latch and the latch hole, thereby releasing the sliding movement. The locking between the block unit 3 and the guide rail unit 5 enables the slider unit 3 to slide along the guide rail unit 5 to drive the swing arm unit 4 thereon to move. Next, its structure will be described in detail.

(method one)

As shown in FIGS. 12 to 15 , in the guide rail unit 5 , a plurality of latch holes (engagement holes) 54 are provided in the support base 51 along the length direction of the guide rail 52 . Here, the intervals between the plurality of latch holes 54 may be equal, or they may be arranged at specific positions on the support base 51 according to the required height of the slider unit 3 for specific exercise items. In addition, in the illustration, the latch hole 54 is provided in the support base 51 as an example. However, the latch hole 54 may be disposed directly on the guide rail 52 instead of the support base 51 . . Here, from the viewpoint of the stress on the guide rail and the protection of the guide rail, it is preferable not to provide the latch hole 54 directly in the guide rail 52 but to provide the latch hole 54 in the support base 51 .

In addition, as shown in FIGS. 12 to 14 , a height position sensor 55 may also be provided along the length direction of the guide rail 52 . By providing the height position sensor 55 , the height of the slider unit 3 (or slider 31 ) can be detected. Location. In the present invention, there is no limit to the height position sensor 55. For example, a photosensitive sensor or a pressure sensor can be used. As long as the height position of the slider unit 3 (or slider 31) can be detected, the height position sensor 55 can be used. It is not limited. In addition, it is preferable to dispose the height position sensor 55 on the opposite side of the guide rail 52 close to the support base 51 so as to detect the height position of the slider 31 more accurately and sensitively. In addition, because the base end of the swing arm unit 4 connected to the slider unit 3 and the slider unit 3 are always maintained at the same height position, the slider can also be obtained by detecting the base end of the swing arm unit 4. The height position of the block unit 3 (slider 31) is not limited.

In addition, as shown in FIGS. 12 to 15 , corresponding to the latch hole 54 described above, in the slider unit 3 A latch (engagement pin) 343 that can be inserted into the latch hole 54 is provided inside. Thus, by inserting the latch pins 343 into the latch holes 343 provided at different positions of the guide rail unit 5, the position of the slider unit 3 relative to the guide rail unit 5 is locked, thereby also realizing the base end of the swing arm unit 4. The position of the head is locked. In addition, when the desired position, especially the height position, is adjusted according to the needs of the user, the fixation (locking) of the slider unit 3 relative to the guide rail unit 5 can be released by simply pulling out the latch 343 from the latch hole 54 , the slider unit 3 returns to a state in which it can slide on the guide rail unit 5. At this time, the user only needs to push the slider 3 to slide the slider unit 3 to the required height position, and insert the latch 343 again. The slider unit 3 can be fixed relative to the guide rail unit 5 by entering the latch hole 54 .

Here, as a specific example of using the plug-and-pull coupling of the latch 343 with respect to the latch hole 54, for example, as shown in FIGS. The height adjustment part 34 can pull out the latch 343 from the latch hole 54 .

As shown in FIGS. 14 and 15 , the height adjustment part 34 mainly includes: a connecting rod 342 that is generally in the shape of a long rod; an adjustment handle 341 fixedly installed on the upper end of the connecting rod 342 (upper in the up-down direction in FIG. 15 ); The latch installation part 346 at the midway position of the connecting rod 342; the fixing part 344 provided at the lower end of the connecting rod 342; and the latch installation part 346 provided relative to the latch installed on the support seat 51 of the guide rail unit 5. The hole 54 allows the plug 343 (engagement pin) to be inserted and removed.

In this embodiment, as shown in Figures 12 to 15, the connecting rod 342 is generally linear in shape and is arranged along the up and down direction. The adjusting handle 341 is fixedly provided on the upper end of the connecting rod 342, and the upper end of the connecting rod 342 The adjustment handle 341 can be exposed from above. For example, as shown in FIGS. 12 and 13 , the adjustment handle 341 can be exposed from the opening 46 opened in the housing 45 of the swing arm unit 4 . In addition, a latch mounting portion 346 is provided at a midway position of the connecting rod 342, and the latch 343 can be mounted on the latch mounting portion 346. As for the method of installing the latch 343 on the latch mounting portion 346, for example, as shown in FIGS. 12 to 15 and FIG. 17 described later, the latch 343 can be fixed in the length direction of the connecting rod 342 ( 15 ) in a substantially vertical manner. At this time, as shown in FIGS. 12 to 15 , in a state where the height adjustment portion 34 is installed on the fitness equipment F, the guide rail unit 5 (guide rail 52) and connecting rod 342 as a whole The latch 343 extends substantially linearly along the up and down direction, and the latch 343 is approximately perpendicular to the length direction of the connecting rod 342 . Therefore, the latch 343 is also approximately perpendicular to the guide rail 52 (guide rail unit 5 ), and the latch 343 faces the insertion direction of the latch hole 54 It is also substantially perpendicular to the guide rail 52 (guide rail unit 5).

In addition, the fixed portion 344 of the connecting rod 342 is rotatably fixed to the inner lower end of the slider unit 3 through a pivot, a hinge, or other structures. That is, as shown in FIGS. 12 to 15 , the height adjustment part 34 as a whole can rotate around the fixed part 344 with the fixed part 344 as the axis (actually, specifically, it can rotate with the pin etc. fixing the fixed part 344 as the axis. ). At this time, when the height adjustment part 34 as a whole rotates with the fixed part 344 as the axis, the insertion and extraction of the latch 343 with respect to the latch hole 54 of the guide rail unit 5 can be realized, so that the slider unit 3 can be realized with respect to the guide rail unit. 5 is fixed and released, thereby adjusting and positioning the slider unit 3 and the swing arm unit 4 connected thereto.

Specifically, when the user needs to adjust the height position of the swing arm unit 4, the user only needs to hold the adjustment handle 341 of the height adjustment part 34 with his hand, and adjust the height position in the counterclockwise direction in the state shown in Figure 15. When the adjustment handle 341 exerts force, the height adjustment part 34 can rotate in the counterclockwise direction with the fixed part 344 as the axis, thereby driving the latch 343 provided on the connecting rod 342 to move to the left side in FIG. 14 , causing the latch 343 Pull it out from the latch hole 54 of the guide rail unit 5 . When the latch 343 is pulled out from the latch hole 54 of the guide rail unit 5, the slider unit 3 and the guide rail unit 5 are in a state where the slider unit 3 can slide freely on the guide rail unit 5. At this time, you only need to continue to hold the adjustment handle 341 By pulling it up or pushing it down, the slider unit 3 can slide up and down along the guide rail unit 5, thereby driving the swing arm unit 4 to move up and down along the guide rail unit 5. At this time, when the slider unit 3 slides to the height position desired by the user, the user only needs to hold the adjustment handle 341 and exert a clockwise force on it in the state shown in Figure 15, so that the height can be adjusted. The part 34 rotates in the clockwise direction with the fixed part 344 as the axis, thereby driving the latch 343 provided on the connecting rod 342 to move to the right side of FIG. 14 , so that the latch 343 is inserted into the latch hole 54 of the guide rail unit 5 to achieve The positioning of the slider unit 3 is fixed relative to the guide rail unit 5 to complete the height adjustment.

In addition, in order to facilitate the rotation of the height adjustment part 34, as shown in FIGS. 12 to 15 , a spring member 345 such as a coil spring may be provided in the center of which the latch 343 can be inserted. In the illustrated example, by arranging the latch 343 to have a stepped flange portion (for example, a shape similar to a bolt head) and setting the diameter of the flange portion of the latch 343 to be larger than that of the latch 343 . The diameter of the spring member 345 of the coil spring is such that the spring member 345 can be held between the flange portion of the latch 343 (the left end of the flange portion of the latch 343 in FIG. 15 ) and the housing of the slider unit 3 (such as the slider holder). 32) without falling. At this time, it is preferable that when the latch 343 is inserted into the latch hole 54 of the guide rail unit 5, the spring member 345 is in a compressed state, so that the thrust exerted on the latch 343 when the spring member 345 abuts the flange portion of the latch 343 can be utilized. To lock the positioning and fixation of the slider unit 3 relative to the guide rail unit 5 . In addition, preferably when the latch 343 is pulled out from the latch hole 54 of the guide rail unit 5, the spring member 345 can be further compressed at this time, so that when the slider unit 3 slides to a prescribed height position, the spring member 345 can be used The elastic restoring force assists the user to operate the height adjustment portion 34 to reinsert the latch 343 into the latch hole 54 to position the slider unit 3 relative to the guide rail unit 5 . The above setting of the spring member 345 is only an example. The contact positions of both ends of the spring member 345 can also be changed, the compression and tension conditions in each state can also be changed, or one end of the spring member 345 can be fixed on on other parts. The spring member 345 is preferably set so that when the latch 343 is inserted into the latch hole 54 of the guide rail unit 5, it can lock the slider unit 3 and the guide rail unit 5 relative to each other. When the latch 343 is pulled out from the latch hole 54, After being pulled out and inserted into other latch holes 54 again, it can play a role of assisting insertion.

In addition, in the present invention, there is no restriction on the specific shape of the connecting rod 342, and it can be a long rod with a rectangular cross-section or a circular cross-section, taking into account the installation and fixation of the latch 343 relative to the latch mounting part 346 and the fixing part 344. It is rotatable and fixed. It is preferable to set the connecting rod 342 in a concave (groove-shaped, U-shaped) cross-section, so that the latch 343 and the fixing part 344 can be easily installed and fixed by using components such as a plug shaft or a bolt. In addition, considering factors such as the smoothness of the latch 343 being inserted into the latch hole 54, as shown in FIGS. 12 to 15 or the later-described FIG. ) Install the latch 343 to the latch installation part 346 with a certain deviation margin, so that the latch 343 can be inserted and removed from the latch hole 54 more smoothly when the height adjustment part 34 is operated.

In addition, in the example shown in the figure, in order to facilitate the installation of the adjustment handle 341, the upper end of the connecting rod 342 is formed in a bent shape, so that the entire connecting rod 342 is generally L-shaped, but the present invention is not limited to this. The connecting rod 342 may be formed into other shapes.

(Method 2)

In the above "Method 1", the case of manually inserting and removing the latch relative to the latch hole to adjust the height position of the slider unit 3 is explained as an example. However, this method The invention is not limited to this, and other methods can also be used to insert and remove the plug relative to the plug hole. In the present invention, as another way of inserting and removing the latch with respect to the latch hole to realize the positioning, fixation and release of the slider unit 3 with respect to the guide rail unit 5, for example, a motor and a cam structure can be used to automatically align the slider unit 3 with the guide rail unit 5. The height position of block unit 3 is adjusted.

Specifically, as shown in FIGS. 16 to 18 , the slider unit 3 is provided with a height adjustment portion 35 capable of inserting the latch 353 into the latch hole 54 and extracting the latch 353 from the latch hole 54 . The adjustment part 35 mainly includes: a connecting rod 352 that is generally in the shape of a long rod; a cam contact part 351 fixedly installed on the upper end of the connecting rod 352 (upper part in the up-down direction of FIGS. 17 and 18 ); The latch mounting part 358 at the midway position; the fixing part 354 provided at the lower end of the connecting rod 352; and the latch mounting part 358 is capable of being inserted and removed from the latch hole 54 provided on the support seat 51 of the guide rail unit 5 The latch 353 (latching pin).

In this embodiment, as shown in FIGS. 16 to 18 , substantially the same as the above-mentioned "method 1", the connecting rod 352 is substantially straight as a whole and is arranged along the up and down direction. In addition, in this embodiment, an adjustment handle is not provided, but a cam contact portion 351 is fixedly provided at the upper end of the connecting rod 352 . In addition, a latch mounting portion 358 is also provided at a midway position of the connecting rod 352, and the latch 353 can be mounted on the latch mounting portion 358. The method of installing the latch 353 on the latch mounting portion 358 is roughly the same as the above-mentioned "Method 1". For example, as shown in Figures 17 and 18, the latch 353 can be fixed relative to the connection by using a plug shaft fixation method. The length direction of the rod 352 (the up-and-down direction in FIGS. 17 and 18 ) is substantially vertical, and the latch 353 is installed on the latch mounting portion 358 . At this time, as shown in FIGS. 17 and 18 , the height adjustment portion 35 is installed on When the fitness equipment F is on the fitness equipment F, the guide rail unit 5 (guide rail 52) and the connecting rod 352 extend in a substantially straight line in the up and down direction as a whole, and the latch 353 is approximately perpendicular to the length direction of the connecting rod 352, so the latch 353 is relative to the guide rail. 52 (rail unit 5) is also substantially vertical, and the insertion direction of the latch 353 into the latch hole 54 is also substantially perpendicular to the guide rail 52 (rail unit 5).

In addition, as shown in FIGS. 16 to 18 , in this embodiment, the difference from the above-mentioned "Mode 1" is that the height adjustment part 35 includes a motor 356 with a rotating shaft and a cam fixedly connected to the rotating shaft of the motor 356 355. As shown in Figure 17, the cam surface of the cam 355 of the height adjustment portion 35 in this mode can contact the cam contact portion 351. When the motor 356 rotates, the cam 355 also rotates. During the rotation of the cam 355, When the cam contacts When the contact position between the portion 351 and the cam 355 gradually moves from the position where the cam surface of the cam 355 is lower to the position where the cam surface is higher, the cam surface (cam profile) of the cam 355 will move against the cam in contact with it. The contact portion 351 exerts a force so that the cam contact portion 351 can be pushed away from the guide rail unit 5 (to the left in FIGS. 17 and 18 ), so that the height adjustment portion 35 can be adjusted as a whole. The fixed portion 354 rotates about its axis (in FIGS. 17 and 18 , for example, it rotates counterclockwise about the fixed portion 354 ), thereby driving the latch 353 installed on the latch mounting portion 358 to move away from the guide rail unit 5 The latch hole 54 of the guide rail unit 5 is pulled out, and the latch 353 is pulled out from the latch hole 54 of the guide rail unit 5, thereby realizing the release of the fixation of the slider unit 3 relative to the guide rail unit 5.

In addition, as the motor 356 rotates, when the contact position of the cam contact portion 351 and the cam 355 gradually moves from a position where the height of the cam surface of the cam 355 is higher to a position where the height of the cam surface is lower, the cam 355 The cam surface (cam profile) does not apply force to the cam contact portion 351 in contact with it, so that the cam contact portion 351 can return toward the guide rail unit 5 (pushed to the left in FIGS. 17 and 18 ), That is, the height adjustment portion 35 can be rotated as a whole with the fixing portion 354 as the axis (in FIGS. 17 and 18 , for example, in the clockwise direction with the fixation portion 354 as the axis), thereby being able to drive the installation on the latch mounting device. The latch 353 of the portion 358 is inserted into the latch hole 54 of the guide rail unit 5 to realize the fixation of the slider unit 3 relative to the guide rail unit 5 .

In addition, in order to be able to gradually return the contact position of the cam contact portion 351 from a position with a higher height of the cam surface to a position with a lower height of the cam surface as the cam 355 rotates, so that the latch 353 can be restored to the position where the latch 353 is inserted into the latch. The state in the hole 54 realizes the fixation of the slider unit 3 relative to the guide rail unit 5 , and a reset member may be further provided on the height adjustment part 35 . Specifically, as a specific example of the return member, as shown in FIGS. 16 to 18 , the height adjustment portion 35 is further provided with a spring member 357 such as a coil spring into the center of which the latch 353 can be inserted. In the example shown in the figure, the same as the above-mentioned "Method 1", by arranging the latch 353 to have a stepped flange portion (for example, a shape similar to a bolt head) and setting the diameter of the flange portion of the latch 353 To be larger than the diameter of the spring member 357 as a coil spring, the spring member 357 can be held between the flange portion of the latch 353 (the left end of the flange portion of the latch 353 in FIG. between the block holders 32) without falling. At this time, preferably when the latch 353 is inserted into the latch hole 54 of the guide rail unit 5, the spring member 357 is in a compressed state, so that the spring member 357 can be used to abut the latch 353. The flange portion exerts a thrust force on the latch 353 to lock the positioning and fixation of the slider unit 3 relative to the guide rail unit 5 . In addition, preferably when the latch 353 is pulled out from the latch hole 54 of the guide rail unit 5, the spring member 357 can be further compressed at this time, so that when the slider unit 3 slides to a prescribed height position, the spring member 357 can be used With the elastic restoring force, the latch 343 is re-inserted into the latch hole 54 to position the slider unit 3 relative to the guide rail unit 5 . The above setting of the spring member 357 is only an example. The contact positions of both ends of the spring member 357 can also be changed, the compression and tension conditions in each state can also be changed, or one end of the spring member 357 can be fixed on on other parts. The spring member 357 is preferably set so that when the latch 353 is inserted into the latch hole 54 of the guide rail unit 5, it can lock the slider unit 3 and the guide rail unit 5 relative to each other. When the latch 353 is pulled out from the latch hole 54, After being pulled out and inserted into other latch holes 54 again, it can play a role of assisting insertion.

In addition, regarding the specific working process of this embodiment, as shown in FIGS. 16 to 18 , when the latch 353 is kept inserted into the latch hole 54 and the slider unit 3 and the guide rail unit 5 are kept in a locked state, the cam The contact position between the contact portion 351 and the cam 355 is a position where the height of the cam surface is low. At this time, the cam surface of the cam 355 does not exert any force on the cam contact portion 351 (or the cam surface of the cam 355 only contacts the cam The height adjustment portion 351 exerts a small force, which is not enough to rotate the height adjustment portion 35). In addition, by arranging the spring member 357 and maintaining the spring member 357 in a compressed state at this time, one end of the spring member 357 abuts, for example, the slider fixing seat 32 of the slider unit 3 and the other end abuts the latch 353 Applying force to the latch 353 can further ensure that the latch 353 remains inserted into the latch hole 54 . After that, when it is necessary to adjust the height position of the swing arm unit 4, the motor 356 of the height adjustment part 35 is first started to rotate the cam 355. As the cam 355 rotates, the contact position of the cam contact part 351 changes from the cam surface to the position of the cam contact part 351. The lower height position of the cam surface gradually reaches the higher height position of the cam surface, so that the cam surface (cam profile) of the cam 355 can be used to exert force on the cam contact portion 351 that is in contact with it, and further resist the spring member 357 Compressing it pushes the cam contact portion 351 away from the guide rail unit 5 (to the left in FIGS. 17 and 18 ), so that the height adjustment portion 35 as a whole can be adjusted with the fixed portion 354 as the axis. Rotate (for example, rotate in the counterclockwise direction with the fixed portion 354 as the axis in FIGS. 17 and 18 ), thereby driving the latch 353 to move away from the latch hole 54 of the guide rail unit 5 , and remove the latch 353 from the guide rail unit 5 The latch hole 54 is pulled out to realize the release of the fixation of the slider unit 3 relative to the guide rail unit 5. At this time, make the motor 356 stops, and the fixed release state of the slider unit 3 relative to the guide rail unit 5 is maintained, so that the slider unit 3 and the guide rail unit 5 are in a state where the slider unit 3 can relatively slide on the guide rail unit 5 . At this time, just by sliding the slider unit 3 up and down along the guide rail unit 5, the swing arm unit 4 can be driven to move up and down along the guide rail unit 5. Afterwards, when the slider unit 3 slides to the position desired by the user, the motor 356 is restarted to further rotate (or reversely rotate) the cam 355 so that the contact position between the cam contact portion 351 and the cam 355 is shifted from the cam surface. The higher height position gradually returns to the lower height position of the cam surface. At this time, the spring member 357 needs to be restored to its previous state, so that the spring member 357 can be used to drive the entire height adjustment portion 35 to rotate with the fixed portion 354 as the axis in the opposite direction (clockwise in Figures 17 and 18 ). direction of rotation), thereby driving the latch 353 provided on the connecting rod 352 of the height adjustment part 35 to move in the direction of inserting into the latch hole 54 (to the right in Figures 17 and 18), and finally returning the latch 353 to the position where it is inserted into the latch hole 54. The state in the latch hole 54 of the guide rail unit 5 realizes the positioning and fixation of the slider unit 3 relative to the guide rail unit 5, and finally completes the height adjustment.

In addition, the same as the above-mentioned "Method 1", there is no restriction on the specific shape of the connecting rod 352. It can be a long rod with a rectangular cross-section or a circular cross-section. Taking into account the installation and fixation of the latch 353 relative to the latch mounting portion 358 and For rotatable fixation of the fixing part 354, it is preferable to set the connecting rod 352 in a concave (groove-shaped, U-shaped) cross-section, so as to facilitate the installation of the latch 353 and the fixing part 354 using components such as a plug shaft or a bolt. fixed. In addition, considering factors such as the smoothness of the latch 353 being inserted into the latch hole 54, as shown in FIG. 17, it is preferable to use bolting or other methods to loosely install the latch 353 to the latch installation portion (for example, with a certain rotation margin). 356, so that there is a certain deviation margin, so that when the height adjustment part 34 is operated to insert and remove the latch 343 relative to the latch hole 54, it will be smoother.

In addition, in this embodiment, since the insertion and extraction of the latch relative to the latch hole is realized by a motor and a cam structure, a control part or a control unit (not shown) and a button may be further provided. By further combining the motor and the control The bottom part and the button are electrically connected, and the user does not need to hold, for example, an adjustment handle, etc. with his hands to operate, and can control the insertion and extraction of the latch relative to the latch hole through simple touch control, thereby realizing the relative position of the slider unit 3 Fixing and releasing of the guide rail unit 5. As the control unit or the control unit, for example, a computer with a CPU may be used, but the invention is not limited thereto.

In addition, because a height position sensor 54 is also provided along the length direction of the guide rail 52, Therefore, the height position of the slider unit 3 can be automatically detected by the height position sensor 54, and the height of the swing arm unit 4 can be automatically adjusted in combination with the motor 6 as a resistance source.

Specifically, for example, the main body 1 is also provided with components such as a computer with a CPU as a control unit and a memory (such as a hard disk, RAM, ROM and EEPROM) storing data and programs, which will be used as a touch electronic screen or The front panel 2 formed of an operation panel serves as an operation interface that the user can operate, and electrically connects components such as the resistance source motor 6 and the motor 356 of the height adjustment section 35 with the control section, the operation interface, the height position sensor 55 and the like.

At this time, when the user needs to adjust the height position of the slider unit 3 (swing arm unit 4), he can first set the target height that he wants to adjust. For example, the user can input the target height position information that he wants to adjust through an operation interface, etc. and store it in the memory. In addition, the control part controls the height position sensor 55 to detect the current position of the slider unit 3, obtain the current height position information of the slider unit 3, and store it in the memory. After that, the control unit compares the target height position information set by the user with the existing height position information detected by the height position sensor 55 to obtain the corresponding relationship between the current height position and the target height position of the slider unit 3 , for example, the current height position of the slider unit 3 is higher than the target height position or the current height position of the slider unit 3 is lower than the target height position, etc.

Thereafter, the control unit controls the height adjustment unit to release the locked state so that the slider unit 3 can slide freely on the guide rail unit 5 . Specifically, the control unit controls the height adjustment unit 35 to rotate the motor 356 of the height adjustment unit 35 to rotate the cam 355 fixed on the rotating shaft of the motor 356. During the rotation of the cam 355, the cam contact portion 351 in contact with the cam 355 follows the cam surface (cam profile) of the cam 355 and moves linearly. At this time, when the contact position of the cam contact portion 351 and the cam 355 gradually moves from the position where the height of the cam surface of the cam 355 is low to the position where the height of the cam surface is high, the cam surface (cam profile) of the cam 355 A force is exerted on the cam contact portion 351 that is in contact with it, so that the cam contact portion 351 can be pushed away from the guide rail unit 5 (to the left in FIGS. 17 and 18 ), thereby increasing the height of the cam contact portion 351 . The adjusting part 35 can rotate as a whole with the fixed part 354 as the axis (in FIGS. 17 and 18 , for example, with the fixed part 354 as the axis in the counterclockwise direction), thereby driving the latch installed on the latch mounting part 358 353 is moved away from the latch hole 54 of the guide rail unit 5, and the latch 353 is pulled out from the latch hole 54 of the guide rail unit 5, thereby releasing the fixation of the slider unit 3 relative to the guide rail unit 5. That is, under the control of the control unit, the height adjustment unit releases the locked state and brings the slider unit 3 into a state in which it can slide freely on the guide rail unit 5 . At this time, the control part stops the side to maintain the state in which the slider unit 3 can slide freely on the guide rail unit 5 .

Thereafter, the correspondence between the current height position and the target height position of the slider unit 3 is obtained based on the comparison between the target height position information set by the user and the existing height position information detected by the height position sensor 55 relationship, when it is determined that the slider unit 3 needs to be raised, as shown in Fig. 32, the control unit controls the resistance source motor 6 to rotate in the direction of winding the rope R around the reel 7 (in Fig. 32, located The resistance source motor 6 marked with a mark on the relatively lower side rotates in the counterclockwise direction, and the resistance source motor 6 on the relatively upper side without a mark rotates in the clockwise direction), so that the holding portion (not shown in the figure) connected to the rope R, 32 ) is pulled upward by the rope R to contact the front end of the swing arm unit 4 and further drive the slider unit 4 connected to the base end of the swing arm unit 4 to slide upward along the guide rail unit 5 . Alternatively, the correspondence between the current height position and the target height position of the slider unit 3 is based on a comparison between the target height position information set by the user and the existing height position information detected by the height position sensor 55 . relationship, when it is determined that the slider unit 3 needs to be lowered, as shown in FIG. 32 , the control unit controls the resistance source motor 6 to unwind the rope R wound on the reel 7 along the path of the reel 7 . direction of rotation (in Figure 32, the resistance source motor 6 with a label located on the relatively lower side rotates in the clockwise direction, and the resistance source motor 6 with no label located on the relatively upper side rotates in the counterclockwise direction), so that the resistance source motor 6 located on the relatively lower side rotates in the counterclockwise direction), so that the resistance source motor 6 located on the relatively lower side rotates in the counterclockwise direction. The handle portion (not shown) on the front end side of the swing arm unit 4 drops with its own weight, so that the swing arm unit 4 no longer receives the upward force exerted by the handle portion in contact with the front end portion of the swing arm unit 4, so that the slider unit 3 and the swing arm unit 4 can also slide downward along the guide rail unit 5 by their own weight.

Afterwards, when the height position sensor 55 detects that the slider unit 3 moves to the target height position set by the user, the motor 356 of the height adjustment part 35 is controlled to restart and rotate further (the motor 356 of the height adjustment part 35 may also be controlled). Reverse rotation), so that the cam 355 fixed on the rotating shaft of the motor 356 rotates again. During the rotation of the cam 355, as described above, the cam contact portion 351 in contact with the cam 355 follows the cam surface (cam profile) of the cam 355 and moves linearly. At this time, when the cam contact portion 351 and the cam 355 When the contact position gradually returns from the position where the height of the cam surface is high to the position where the height of the cam surface is low, the entire height adjustment part 35 rotates in the opposite direction to the previous one with the fixing part 354 as the axis (Fig. 17 and Fig. 18), thereby driving the latch 353 provided on the connecting rod 352 of the height adjustment part 35 to move in the direction of inserting into the latch hole 54 (moving to the right in Figures 17 and 18), and finally the latch 353 353 returns to the state of being inserted into the latch hole 54 of the guide rail unit 5 to realize the positioning and fixation of the slider unit 3 relative to the guide rail unit 5 . That is, when the height position sensor 55 detects that the slider unit 3 moves to the target height position set by the user, the control pin 353 is inserted into the latch hole 54 so that the slider unit 3 and the guide rail unit 5 become a lock that cannot move relative to each other. stop state.

At this point, the height adjustment of the slider unit 3 is finally completed. In this process, the user only needs to set the desired height position information without cumbersome adjustment operations. The user can cleverly use the resistance source motor and the connection position relationship between various components to automatically adjust the slider unit 3 Adjust the height position.

In addition, in the present invention, adjusting the height position of the slider unit 3 actually means adjusting the height position of the base end of the swing arm unit 4 connected to the slider unit 3, thereby adjusting the height of the swing arm unit 4. Adjust the position.

(Method 3)

As another specific example of the insertion and extraction of the latch relative to the latch hole of the present invention, as shown in Figures 19 and 20, a worm latch can also be used as the latch and coupled with a motor to realize automatic insertion and extraction of the worm latch relative to the latch hole. .

Specifically, as shown in FIGS. 19 and 20 , the slider unit 3 is provided with a height adjustment portion 36 capable of inserting the worm pin 361 into the pin hole 54 and extracting the worm pin 361 from the pin hole 54 . As shown in Figures 19 and 20, the height adjustment part 36 mainly includes: a worm pin 361 with helical teeth 366 on part of the surface; a motor 363 with a rotating shaft; and a helical tooth 366 fixed on the motor shaft that can be connected to the worm pin 361. Meshing gears 362. In this embodiment, as shown in FIGS. 19 and 20 , the worm latch 361 is rotatably fixed to the slider fixing seat of the slider unit 3 and/or the swing arm unit 4 using a worm bearing 364, a worm fixing member 365, etc. The swing arm fixed seat, and the helical teeth 366 of the worm pin 361 always remain in mesh with the gear 362 on the rotating shaft of the motor 363, and there is no part of the helical teeth 366 (such as the insertion part on the right side of the helical teeth 366 in Figure 19 367) can be inserted into the latch hole 54 as a fixing pin. In addition, the motor 363 is also connected to a control switch and a control switch not shown in the figure. Control and other electrical connections.

In this embodiment, the insertion portion 367 of the worm pin 361 can be inserted into the pin hole 54. When the height position of the slider unit 3 needs to be adjusted, the user only needs to control the motor 363 through the control portion or control switch. , the insertion portion 367 of the worm pin 361 is pulled out from the latch hole 54 or inserted into the latch hole 54 at a different position, and the height position of the slider unit 3 can be adjusted according to the actual use situation and exercise content, and the slider unit 3 can be It is locked at a prescribed position on the guide rail 52 of the guide rail unit 5 .

For example, in this embodiment, when the control unit receives a height adjustment instruction from the user, the motor 363 is started to rotate, and the gear 362 installed on the motor shaft is used to drive the worm pin 361 meshed with it to move (Fig. 19, up and down in FIG. 20), so that the insertion part 367 of the worm latch 361 can be driven to be inserted or pulled out relative to the latch hole 54 by the forward or reverse rotation of the motor 363, so as to release the relative movement of the slider unit 3. Locking the guide rail unit 5 (guide rail 52 ) or fixing the slider unit 3 relative to the guide rail unit 5 (guide rail 52 ).

More specifically, in a specific example, when the user needs to adjust the height position of the slider unit 3 , an adjustment instruction is sent to the control part through a special switch or a touch screen and switch on the front panel 2 . After receiving the height adjustment instruction from the user, the control part starts the motor 363, for example, to rotate forward, and uses the gear 362 installed on the motor shaft to drive the worm latch 361 meshed with it to move in the direction of unlocking (shown in Figure 19). The worm latch 361 moves to the left (in FIG. 20 , the worm latch 361 moves upward), thereby pulling out the insertion portion 367 from the latch hole 54, and then the operation of the motor 363 is stopped. At this time, the lock between the slider unit 3 and the guide rail unit 5 is released, and the slider unit 3 is in a sliding state relative to the guide rail unit 5. Just slide the slider unit 3 up and down along the guide rail unit 5 to drive the The swing arm unit 4 moves up and down along the guide rail unit 5 . After that, when the slider unit 3 slides to the position desired by the user, the motor 363 is restarted to reverse the direction (opposite to the direction of rotation when unlocking), and the gear 362 installed on the motor shaft is used to drive it. The engaged worm bolt 361 moves in the locking direction (the worm bolt 361 is moved to the right in Figure 19 and the worm bolt 361 is moved downward in Figure 20), thereby reinserting the insertion portion 367 into the bolt hole 54, and then stopping the motor. 363 operation. At this time, the slider unit 3 and the guide rail unit 5 are in a locked state, thereby realizing the positioning and fixation of the slider unit 3 relative to the guide rail unit 5, and finally completing the height adjustment.

In addition, because the height position sensor 54 is also provided along the length direction of the guide rail 52, the height position of the slider unit 3 can be automatically detected by the height position sensor 54, and the swing arm can be realized by combining the motor 6 as a resistance source. Automatic adjustment of the height of unit 4.

Specifically, because the locking and unlocking of the slider unit 3 with respect to the guide rail unit 5 of the present invention can be realized without using the manual push and pull of the slider unit 3, the fixation of the swing arm unit can be automatically unlocked and the swing arm unit can be realized. 4 automatic height adjustments.

For example, when it is necessary to adjust the swing arm unit 4 to rise, when starting to use the fitness equipment and preparing to adjust the height position of the swing arm unit 4, the user can input the desired height adjustment through, for example, the touch screen of the front panel 2 location information. When the control unit (such as a computer, etc.) receives the height adjustment instruction from the user, it first rotates the motor 363, and uses the gear 362 on the motor 363 to drive the worm latch 361 back (to the left in Figure 19, to the left in Figure 20 move upward), the worm latch 361 is disengaged from the latch hole 54, thereby releasing the lock of the slider unit 3 relative to the guide rail unit 5, so that the slider unit 3 and the swing arm unit 4 (the base end of the swing arm unit 4) can Slides freely along the guide rail unit 5 as a whole.

At this time, when you want to raise the height position of the swing arm unit 4, you only need to control the motor 6 as the resistance source through the control unit, so that the motor 6 rotates in a direction that enables the rope R to be wound into the reel 7 ( Rotate in the direction of keeping the rope R in a tight state), and by winding the rope R into the reel 7, according to the resistance transmission relationship between the rope R and the swing arm unit 4 shown in Figure 32, the position of the swing arm unit 4 is For example, the gripping part (not shown) at the front end will rise as the rope R is wound, and get stuck at the front end of the swing arm unit 4 (roughly the position shown by the wrist joint pulley d5 and the outlet end in Figure 32). Take the swing arm unit 4 and the slider unit 3 to rise together. After that, when the height position sensor 32 detects that the swing arm unit 4 and the slider unit 3 rise to the specified position, it again sends an instruction to the control unit to stop the operation of the motor 6, thereby positioning the swing arm unit 4 and the slider unit 3 to the specified position. height position.

After that, the control unit rotates the motor 363 in the opposite direction to the above-mentioned direction, and uses the meshing of the gear 362 on the motor 363 with the helical teeth 366 on the worm pin 361 to drive the worm pin 361 forward, so that the worm pin 361 is inserted into the pin hole 31 , so that the slider unit 3 is locked relative to the guide rail unit 5 , so that the slider unit 3 and the swing arm unit 4 are fixed at a prescribed position as a whole, and the upward adjustment of the swing arm unit 4 is completed.

In addition, when it is necessary to adjust the swing arm unit 4 to lower, when starting to use the fitness equipment and preparing to adjust the height position of the swing arm unit 4, the user can input the desired height adjustment through, for example, the touch screen of the front panel 2 location information. When the control unit receives the height adjustment instruction from the user, it first rotates the motor 363 and uses the gear 362 on the motor 363 to drive the worm latch 361 back (to the left in Figure 19 and upward in Figure 20), so that The worm latch 361 is disengaged from the latch hole 31 , thereby unlocking the slider unit 3 relative to the guide rail unit 5 , so that the slider unit 3 and the swing arm unit 4 can slide freely along the guide rail unit 5 as a whole.

At this time, when you want to lower the height position of the swing arm unit 4, the control unit controls the motor 6 as a source of resistance so that the motor 6 rotates in a direction that allows the rope R to be pulled out of the reel 7 (so that the rope R can be pulled out of the reel 7). The rope R wound on the reel 7 is in a slack state). At this time, because the slider unit 3 and the swing arm unit 4 as a whole are in a state of being able to slide freely along the guide rail unit 5, and the rope R wound around the reel 7 is in a relaxed state, the sliding The block unit 3 and the swing arm unit 4 are not constrained by the rope R. The slider unit 3 and the swing arm unit 4 can freely slide downward along the guide rail unit 5 using their own gravity. According to the rope R and the swing arm unit 5 shown in Figure 32 Due to the resistance transmission relationship of the arm unit 4, the swing arm unit 4 will hit the handle located at the front end of the swing arm unit 4 and because the rope R of the reel 7 is in a relaxed state at this time, the swing arm unit 4 will hit the When the height position sensor 32 detects that the swing arm unit 4 and the slider unit 3 have dropped to the specified position, it sends a signal to the control unit to stop the rotation of the motor 6 and maintain it at a level that enables the swing arm unit to 4 and the instruction of the power state in which the slider unit 3 remains stationary (that is, the power of the motor 6 can at least resist the gravity of the slider unit 3 and the swing arm unit 4 without causing the slider unit 3 and the swing arm unit 4 to continue to slide freely. ), position the swing arm unit 4 and the slider unit 3 to the specified position.

After that, the control unit rotates the motor 363 in the opposite direction to the above-mentioned direction, and uses the meshing of the gear 362 on the motor 363 with the helical teeth 366 on the worm pin 361 to drive the worm pin 361 forward, so that the worm pin 361 is inserted into the pin hole 31 , so that the slider unit 3 is locked relative to the guide rail unit 5 , so that the slider unit 3 and the swing arm unit 4 are fixed at a predetermined position as a whole. At this point, the lowering adjustment of the swing arm unit 4 is completed.

Through the present invention, there is no need for the user to manually adjust the height of the swing arm one by one on one side, and the height of the swing arm can be adjusted automatically, even when facing different parts at one time. During comprehensive training of multiple movements, the height of the swing arm can be switched accurately and quickly, and the user does not need to worry about adjustment misalignment. The adjustment work can be completed accurately at one time, allowing the user to devote himself wholeheartedly to It provides users with a good experience during exercise.

In addition, the above example illustrates the case of automatic height adjustment using "Method 3". Similarly, automatic height adjustment is also applicable to the case of "Method 2".

(Method 4)

The above description has been made taking the latch and the latch hole as an example. However, an electromagnetic locking block that can electromagnetically attract each other can also be provided, that is, a locking piece and a locked part are provided to replace the latch and the latch hole respectively, and the locking piece and the locked part are replaced. The lock part is formed in the form of an electromagnetic lock. By arranging in this way, there is no need to drill holes in the guide rail unit 5 in order to provide latch holes, and the strength of the guide rail unit 5 can be improved. Moreover, the slider unit 3 can be locked to the guide rail unit 5 without being limited by the number and position of the latch holes. Any position along the length direction makes it possible to fine-tune the height position, thus giving users a better experience. In addition, the use of electromagnetic locks can also make the structure more compact.

In addition, when electromagnetic lock blocks capable of electromagnetically attracting each other are provided, the control unit can also be used to control the resistance source motor 6 to achieve automatic adjustment of the height position as described in each of the above modes, which will not be described again.

-Swing arm self-storing structure-

The above describes the positioning and fixing of the slider unit relative to the guide rail unit and the release of the fixation, and also explains the height adjustment method when using the fitness equipment of the present invention. In addition, when the fitness equipment is not in use, such as at the end of exercise, the fitness equipment in the prior art usually leaves the arm in the state of the last exercise item without storing it.

In this regard, in the present invention, the control unit can be used to control the resistance source motor 6 to return the slider unit 3 and the swing arm unit 4 to the stored state. For example, the relevant program can be stored in the storage unit in advance. When the control unit receives the user's storage instruction, the control unit controls the resistance source motor 6 to rotate in the direction of winding the rope R around the reel 7. Therefore, as described above, the handle and other components provided at the front end of the swing arm unit 4 contact the front end of the swing arm unit 4 and drive the swing arm unit 4 and the slider unit 3 to rise to the storage position shown in FIG. 4 , for example. The automatic storage of the swing arm unit 4 is realized. At this time, the swing arm unit 4 can After completing the automatic storage, the control unit can further control and automatically cut off the power of the fitness equipment.

In addition, the control part can also be used to control the resistance source motor 6 so that the slider unit 3 and the swing arm unit 4 automatically return to the storage state when the fitness equipment is in an idle state. For example, the idle time (standby time) of the fitness equipment can be set in advance and stored in the storage unit. When the fitness equipment exceeds the prescribed time, the control unit automatically controls the resistance source motor 6 to move along the The rope R rotates in the direction in which the rope R is wound around the reel 7. As described above, the handle and other components provided at the front end of the swing arm unit 4 come into contact with the front end of the swing arm unit 4, thereby driving the swing arm unit 4 and the slider unit. 3 rises to the storage position shown in Figure 4, for example, to realize automatic storage when the fitness equipment is idle. At this time, after the swing arm unit 4 completes the automatic storage in the idle state, the control unit may further control to automatically cut off the power of the fitness equipment.

As a result, not only can the swing arm unit be quickly stored after the exercise, but also the swing arm unit can be automatically stored and the power is cut off when the standby period is exceeded. This not only makes the home environment tidy, but also saves energy waste.

-Angle adjustment structure of the swing arm of the swing arm unit-

The above description has mainly been made on the case where the slider unit 3 and the swing arm unit 4 of the present invention move in the up-and-down direction along the rail unit 5 . Thereby, the user can adjust the height position of the slider unit 3 and fix it at a desired position on the guide rail unit 5 after adjustment. However, even if the slider unit 3 and the swing arm unit 4 have been fixed at the desired fixed position, depending on the user's height and the requirements of the exercise program, sometimes it is still necessary to adjust the swing arm 42 of the swing arm unit 4, for example Adjust the position in the vertical plane. For example, as shown in FIG. 10 , the base end of the swing arm unit 4 is fixed to the slider unit 3 , but the front end of the swing arm unit 4 (swing arm 42 ) needs to be able to move in the vertical plane (as shown in FIG. 1 state) can be rotated at a predetermined angle around the base end (around the slider unit 3) and fixed at a desired angle.

In the present invention, by designing the structure of the swing arm unit 4, as described later, the adjustment pin 424 and the adjustment pin fixing plate 425 are used to realize the angle change of the swing arm 42 of the swing arm unit 4 in the vertical plane.

Specifically, as shown in FIGS. 21 to 25 , the swing arm 42 has: a substantially elongated swing arm main body part 421; and a base end connection part 422, which is fixed to the base end side of the swing arm main body part 421. and is rotatably connected to the swing arm fixing base 41; the adjustment pin 424 can be extended or retracted from the base end side of the swing arm main body 421 along the length direction of the swing arm main body 421 inside the swing arm main body 421. Back; a generally disc-shaped adjusting pin fixed plate 425, the adjusting pin fixed plate 425 is fixed to the swing arm fixed base 41, on which is provided with a plurality of bayonet 429 into which the adjusting pin 424 can be inserted and engaged.

In the embodiment of the present invention, as shown in FIG. 22 , the base end connecting portion 422 is fixed to the base end side of the swing arm main body 421 and is rotatable with the swing arm main body 421 as a whole through bearings or engagement structures. By being attached to the swing arm fixing base 41 , the swing arm main body 421 can be rotated around the base end connecting portion 422 as the center (axis center). In this embodiment, it is preferable that the swing arm main body part 421 is formed in a hollow cylindrical shape.

In addition, a substantially disk-shaped adjusting pin fixing plate 425 is also provided on the swing arm fixing base 41 . In the example shown in the figure, the adjusting pin fixing plate 425 is fixedly installed on the swing arm fixing base 41 substantially vertically, and is provided with a plurality of bayonet openings on the outer side along the circumferential direction into which the adjusting pin 424 can be inserted and engaged. 429, that is, the adjusting pin fixed plate 425 is generally in the shape of an index plate. The intervals between the plurality of bayonet ports 429 may be equal, or may be set to different intervals as required. In the illustrated example, as shown in FIGS. 22 and 23 , when the adjustment pin 424 is inserted into the lowermost bayonet 429 , the entire swing arm unit 4 is in a vertical state along the extension direction of the guide rail unit 5 (for example, Storage state), at this time, for example, it is used to store the swing arm unit 4. In addition, as shown in Figure 23, starting from the bottom bayonet 429, other bayonet 429 are formed on the outer periphery of the adjusting pin fixed plate 425 in the clockwise direction. When the adjustment pin 424 is inserted into the bottom bayonet 429, In other bayonet 429 other than the opening 429, the swing arm main body 421 is changed from the vertical state along the extension direction of the guide rail unit 5 to the rotating state. At this time, the angle of the swing arm unit 4 is adjusted. state. Here, the distance between the bottommost bayonet 429 and the other bayonet 429 immediately adjacent to it can be set to be greater than the distance between the other bayonet 429 except the bottommost bayonet 429 to facilitate operation (the bottommost bayonet 429 Used for storage, others for adjustment). 24(a) to (c) schematically show the process of changing the adjustment pin 424 from one bayonet 429 to another bayonet 429, but the above process and the setting of the interval are just an example and can be changed as needed. .

In addition, as shown in FIG. 23 , a structure is provided inside the swing arm main body 421 that can extend from the base end side of the swing arm main body 421 along the length direction of the swing arm main body 421 . or retracted adjustment pin 424. When the adjustment pin 424 is extended and fixed with the adjustment pin When a certain bayonet 429 of the disk 425 is engaged, the entire swing arm 42 can be locked at the rotation angle corresponding to the bayonet 429; when the adjustment pin 424 retracts to the swing arm main body 421, the adjustment pin 424 and the adjustment pin When the engagement of the bayonet 429 of the fixed plate 425 is released, the swing arm main body 421 can rotate in the vertical plane with the base end connection portion 422 as the center, for example, in the state shown in FIG. 6 .

Regarding the specific method of extending the adjusting pin 424 and engaging it in the bayonet 429 of the adjusting pin fixing plate 425, refer to Figures 21 to 25. A connecting rod 426 and an adjusting switch 427 are also provided inside the swing arm main body 421. One end of the connecting rod 426 is connected to the end of the adjusting pin 424 (the other end opposite to the end of the adjusting pin 424 inserted into the bayonet 429), and the other end is connected to the adjusting switch 427.

Among them, in this embodiment, as shown in Figure 25, the adjustment switch 427 is set to be roughly L-shaped, and the adjustment switch 427 is rotatably installed at the L-shaped inflection point of the adjustment switch 427 through a pin. The main body part 421 of the swing arm can rotate around the pin axis (the L-shaped adjustment switch 427 in Figure 25 can rotate clockwise or counterclockwise around the pin axis).

In addition, one end of the L-shaped adjustment switch 427 is rotatably fixed to one end of the link 426 in the swing arm main body 421 . That is, as shown in FIG. 25 , for the L-shaped adjustment switch 427 and the link 426 , the L-shaped inflection point of the adjustment switch 427 is fixed to the swing arm main body 421 , so that the L-shaped adjustment switch 427 and the link 426 form an It is a plane linkage mechanism. At this time, as shown in Figure 25, when the free end of the adjustment switch 427 rotates clockwise, the other end of the adjustment switch 427 connected to the connecting rod 426 will pull the connecting rod 426 upward (swing) in Figure 25 the front end side of the arm) moves; when the free end of the adjustment switch 427 rotates in the counterclockwise direction, the other end of the adjustment switch 427 connected to the link 426 will push the link 426 to the bottom of the swing arm in Figure 25 basal side) moves. At this time, because the base end side of the connecting rod 426 is connected to the end of the adjusting pin 424, when the connecting rod 426 moves up and down due to the rotation of the adjusting switch 427, the adjusting pin 424 on the base end side of the connecting rod 426 also moves along with it. The connecting rod 426 moves up and down, thereby realizing the insertion and extraction of the adjustment pin 424 relative to the bayonet 429 .

In addition, it is preferable that a pin groove 427 for sliding the adjustment pin 424 is provided on the base end side of the swing arm main body 421, and a spring 428 for assisting the adjustment pin 424 to slide up and down is provided between the adjustment pin 424 and the bottom of the pin groove 427.

As described above, by arranging the inside of the swing arm 42 of the present invention, the angle of the swing arm 42 can be adjusted by operating the adjustment switch 427 at the end of the swing arm main body 421 .

In addition, in the present invention, as shown in FIGS. 12 and 16 , the adjustment pin fixing plate 425 may be formed integrally with the swing arm fixing base 41 , or may be provided as an independent component as shown in FIG. 19 . There is no limit to this. In addition, as shown in FIGS. 12 , 16 , 19 and 22 , a proximal end housing 423 may be provided on the proximal end side of the swing arm main body 421 as a rotatable member relative to the swing arm fixing base 41 .

-Elastic pulley module-

As shown in FIG. 12 and FIGS. 26 to 30 , the slider unit 3 also includes an elastic pulley module 33 . Among them, as shown in FIGS. 26 to 30 , the elastic pulley module 33 includes a module frame 331 , a module pulley 332 , and a leg socket 333 . In addition, as shown in FIG. 12 and FIGS. 26 to 30 , the swing arm unit 4 further includes a leg portion 44 provided on the swing arm fixing base 41 . In addition, as shown in FIG. 27 , the guide rail unit 5 also includes a pulley track 53 provided on the support base 51 . In one connection method between the swing arm unit 4 and the slider unit 3 of the present invention, in the elastic pulley module 33, in the example shown in the figure, two module pulleys 332 are provided, and the module pulleys 332 pass through bearings or shafts. Holes, etc. are set up on the module frame 331. The module pulley 332 can slide along the pulley track 53 on the support seat 51 of the guide rail unit 5. The foot socket 333 is opened on the module frame 331 and can provide the swing arm unit 4. The leg portion 44 is inserted into it. That is, as shown in Figures 12 and 13, when the slider 31 of the slider unit 3 slides along the guide rail 52 of the guide rail unit 5, the swing arm unit 4 also slides because the swing arm fixing seat of the swing arm unit 4 The leg portion 44 provided on 41 is inserted into the leg insertion hole 333 of the elastic pulley module 33, so the elastic pulley module 33 also slides along the pulley track 53 of the guide rail unit 5 as the swing arm unit 4 moves. . That is, the slider 31 of the slider unit 3 slides along the guide rail 52 of the guide rail unit 5, and the swing arm unit 4 connected to the slider 31 via the slider fixing seat 32 and the optical axis 43 also slides, and because the swing arm unit The leg portion 44 of 4 is inserted into the leg insertion hole 333 of the elastic pulley module 33, so the elastic pulley module 33 also slides on the pulley track 53 of the guide rail unit 5.

By connecting the swing arm unit 4 and the slider unit 3 in this way, when the user uses the fitness equipment F for training, when the swing arm unit 4 bears an external force, all the external force will not be applied to the guide rail 52 of the guide rail unit 5. Instead, it is partially molded by elastic elastic pulleys. Group 33 suffered. In fitness equipment, the main function of the guide rail 52 is to adjust the height position of the slider unit 3 and the swing arm unit 4, so it needs to maintain smoothness and high precision. When the guide rail 52 bears too much external force, it will It will affect the accuracy and service life of the guide rails 52. If multiple guide rails 52 are used or the width of the guide rails 52 is increased, the manufacturing accuracy of the product and the installation accuracy of the guide rails (maintaining parallelism) need to be further improved accordingly, resulting in complicated installation. And costs go up. In particular, in the present invention, the two guide rail units 5 are not parallel but extend along a straight line and intersect in the extension direction. Therefore, when the swing arm unit 4 bears an external force, it is easier to damage the guide rail unit 5 (the guide rail 52 ). lifespan is affected. In this regard, in the present invention, by arranging the elastic pulley module 33 and allowing it to slide along the pulley track 53, no matter where the slider unit 3 is located, the elastic pulley module 33 will be located at the corresponding height position. , due to the elasticity of the elastic pulley module 33, the foot portion 44 can be in the middle position of the pulley track 33 when it is not subjected to a large external force, so that the foot portion 44 will not come into contact and friction with the pulley track 33, so that in the slider unit 3. Very smooth and noiseless when moving along the guide rail unit. When the swing arm unit 5 receives an external force and transmits it to the slider unit 3, the elastic pulley module 33 deforms, causing the foot portion 44 and the pulley track 33 to come into contact to share the external force received, and share the external force received by the guide rail 52. This will not directly cause damage to the guide rail 52 and play a role in protecting the guide rail 52 .

In addition, since the slider 31 slides along the guide rail 52 smoothly, it is necessary to maintain the accuracy between the slider 31 and the guide rail 52 . In the present invention, even if the external force temporarily affects the accuracy between the slider 31 and the guide rail 52, for example, the slider 31 and the guide rail 52 are slightly offset relative to each other, because of the elastic elastic pulley module 33 provided, This allows the accuracy between the slider 31 and the guide rail 52 to be corrected and restored to the original state, thereby further protecting the guide rail 52 and making it slide more smoothly.

In addition, as shown in Figure 27, it is preferable that on the support base 51 of the guide rail unit 5, the plane where the guide rail 52 for the slide block 31 slides is located relative to the plane where the pulley track 51 for the elastic pulley module 33 slides. It has a certain angle (angle α as shown in the figure). As shown in the figure, when the slider 31 of the slider unit 3 is pressed against the guide rail 52 by an external force, it is usually in a direction transverse to the extension of the guide rail 52 (in the sliding surface of the slider 31, relative to the rail). The guide rail 52 is pressed in a direction perpendicular to the extending direction of the guide rail 52 . In this regard, in the present invention, on the support seat 51 of the guide rail unit 5, the plane where the guide rail 52 for the slide block 31 slides is located relative to the pulley track 51 for the elastic pulley module 33 to slide. There is a certain angle α between the planes, so that the elastic pulley module 33 can better share the external force when the guide rail 52 is subjected to external force, thereby further protecting the guide rail 52 and ensuring smoother sliding. Here, the angle α is preferably an obtuse angle, but is not limited to this and may also be other angles.

In addition, as mentioned above, in the present invention, the leg portion 44 provided on the swing arm fixing base 41 of the swing arm unit 4 can be used, and the leg portion 44 can be inserted into the leg insertion hole opened in the module frame 331 333, the swing arm fixing base 41 and the elastic pulley module 33 can be connected together through a simple structure. Therefore, the slider 31 of the slider unit 3 slides on the guide rail 52 of the guide rail unit 5 , and the slider unit 3 is also connected to the swing arm unit 4 , so that the swing arm unit 4 also slides as the slider unit 3 slides. In the other direction, the swing arm fixed seat 41 of the swing arm unit 4 is connected with the elastic pulley module 33, and the elastic pulley module 33 slides on the pulley track 53 of the guide rail unit 5, so the swing arm unit 4 also follows the pulley. The module 33 slides due to the sliding of the elastic pulley module 33 , and because the swing arm unit 4 is also connected to the slider unit 3 , the slider unit 3 also slides due to the sliding of the elastic pulley module 33 . That is, the swing arm unit 4 and the slider unit 3 slide along the guide rail unit 5 via the slider 31 and the elastic pulley module 33. Regardless of whether the swing arm unit 4 receives an external force or the slider unit 3 receives an external force, they can slide through the elastic pulley. The module 33 is shared, so that the extrusion impact on the guide rail 52 can be reduced, and the guide rail 52 can be further protected to ensure smoother sliding.

In addition, in one embodiment of the present invention, it is preferred that the module pulley 332 is a grooved pulley, and the surface of the pulley track 53 that contacts the grooved pulley is formed into a shape that can fit the groove. In addition, as shown in FIGS. 27 and 28 , it is more preferred that the module pulleys are V-groove pulleys or U-groove pulleys. There are two module pulleys, located at the front and rear ends of the module frame 331 respectively. Thereby, the external force received by the guide rail 52 can be shared more stably.

Above, the elastic pulley module of the present invention is used as a buffer member as an example. However, the present invention is not limited to this, and various modifications can be made.

-Connection method of slider unit and guide rail unit-

In addition, as for the way in which the slider unit 3 is slidably installed on the guide rail unit 5, for example, a slide groove can be provided in the guide rail unit 5 so that the slider unit 3 can be embedded in the slide groove, or the guide rail unit 5 can be formed into an I-shape. The structure of the rail and the slider unit 3 being fitted thereto can also be a combination of slide grooves and rollers, as long as the slider unit 3 can slide along the guide rail unit 5 .

-Other embodiments-

As shown above, as shown in FIGS. 1 to 10 , the left guide rail unit 5 and the right guide rail unit 5 tend to intersect as they go upward (top edge 23 of the main body 1 ) in their respective extending directions. The case will be described as an example, but the present invention is not limited to this. It can also be designed so that the left guide rail unit 5 and the right guide rail unit 5 extend downward (the bottom edge 24 of the main body 1 ) and have a tendency to intersect, or in other ways. In addition, the case where the front panel 2 is in a rectangular shape has been described as an example, but the present invention is not limited thereto, and may also be in a circular, elliptical or other shape. That is, in the present invention, as long as the extending directions of the two guide rail units 5 are not parallel, there is only an included angle between them. At this time, the non-parallel positional relationship of the guide rail unit 5 can be used to form a storage area for the slider unit 3 and the swing arm unit 4, and the front panel 2 can be used to shield the slider unit 3 and the swing arm unit 4 in the stored state.

As a specific example for other cases, for example, the main body part may also be formed into an isosceles trapezoid shape in which the length of the upper base is longer than the length of the lower base (for example, the main body part 1 shown in FIGS. 3 and 31 is inverted. state), and set the guide rail unit along the side of the main body. At this time, contrary to the situation in the above embodiment, the two guide rail units have a tendency to cross along the sides of the main body as they go downwards of the fitness equipment. In this embodiment, in the stored state, the slider unit is located at the lower end of the guide rail unit. When you want to use the fitness equipment, you only need to lift the slider unit to the prescribed position of the guide rail unit.

In addition, as in the case of the above-mentioned embodiment, the shape of the main body portion may not be limited, and the two rail units may be provided so as to have a tendency to cross as they go downwards of the fitness equipment, and the same effect can be obtained.

As mentioned above, in the present invention, there is no need to install special components, and the swing arm unit and the slider unit can be completely hidden in the fitness equipment (front panel) in the stowed state by clever use of the guide rail unit and the front panel. On the back, the swing arm connection structure in the stowed state can be completely hidden, which can make the design of the fitness equipment more integrated. When the fitness equipment is idle and in the stowed state, the overall appearance is more beautiful and suitable for home use. Especially when the fitness equipment is idle, because the swing arm connection structure does not protrude to the side and is completely hidden, the body is more compact and the appearance is more beautiful. In the stored state, the front panel is not even visible at all. Other components, especially when the front panel adopts a mirror display, when powered on, the fitness equipment in the stored state can be used as an entertainment display device Even when the power is off, it can be used as an ordinary mirror. It is not only clean and beautiful in appearance, but also easy to place in the home space for use. It can be fully utilized even when it is idle, and there is no need to set up fitness equipment at home. And ruin the layout of the room.

In addition, the present invention can be suitable for strength training with swing arms at different heights according to various needs. It can achieve various types of exercise with only one fitness equipment. It is easy to use. It not only has a compact structure and does not take up space, but also has a simple appearance. It is aesthetically pleasing and will not affect the overall aesthetics and layout even if it is placed in an ordinary home.

In addition, in order to facilitate users to use training actions such as squats, deadlifts, and high pulls, the position of the rope needs to be a specified distance from the surrounding wall so that when the rope is pulled out corresponding to the training item, the end of the rope will not be disturbed , especially in the low position and high position, strength training requires the outlet end of the rope (refer to Figure 32, the end of the rope R that passes through the swing arm unit 5 and is pulled out from the swing arm unit 5) to cover a larger "output end range" ”, so it has become difficult and important to design a reasonable range of the rope outlet end. Sometimes, if the "outlet end range" is to be met, the fitness equipment needs to be set at a higher height and the fitness equipment 2 itself also needs to be at a higher height.

In the present invention, since the swing arm unit 4 can adjust the height position up and down as the slider unit 3 slides, the length of the swing arm 42 can be compensated, and a shorter swing arm 42 can be used to cover the training range from high to low. . At this time, as shown in Figures 10, 31 and 32, when the fitness equipment F is hung on the wall in the state shown in Figure 10 for use (for example, as shown in Figure 31, by installing the mounting bracket 8 on the wall on the wall, and install the main body 1 of the fitness equipment on the mounting bracket 8, thereby hanging the fitness equipment F on the wall), because the fitness equipment F is hung on the wall at a certain distance from the ground and at the base end of the swing arm unit 4 It can be adjusted up and down along with the slider unit 3, so the front end of the swing arm 42 of the swing arm unit 4 can easily meet the "outlet end range". Therefore, the length of the swing arm 42 can be made shorter, so that the torque endured by the hinge of the swing arm unit 4 and the slider unit 3 will be smaller. In addition, since the base end of the swing arm unit 4 can move toward the ground along the guide rail unit 5, when the fitness equipment F is hung on the wall for use, the front end of the swing arm unit 4 can be brought closer to the ground.

Specifically, in order to facilitate users to perform training actions such as squats, deadlifts, and high back pulls, the outlet end of the rope (the end where the rope R is pulled out through the handle) should cover a larger "outlet end range", such as 10cm to 2m above the ground, and at least 60cm from the wall.

In the present invention, the base end position of the swing arm unit 4 can be adjusted up and down, so the swing arm unit 4 Unit 4 can more easily meet the "outlet end range". For example, when the length of the swing arm is 98cm, the extreme end of the swing arm unit 4 can move within the range of 90cm to 122cm above the ground during use, which can easily meet the requirements. The "outlet end range" makes the length of the swing arm 42 shorter, and the joint at the base end of the swing arm unit 4 connected to the slider unit 3 will bear less torque, which helps protect the service life of the fitness equipment.

The specific embodiments of the present invention have been described above, but those skilled in the art can make various modifications and changes to the embodiments of the present invention without departing from the spirit and scope of the present invention.
