Description

exercise machine {Exercise machine}

The present invention relates to an exercise device, and more particularly, to an exercise device whose shape can be changed while a part is rotated.

In general, a device used for strength exercise is designed to repeat muscle relaxation and contraction while pushing or pulling a lever connected to a weight having a predetermined unit weight. Among the devices for strength training, ARM CURL device for biceps exercise, chest press or butterfly device for chest exercise such as pectoralis major, and pull-up for back muscle exercise Equipment There are various types of exercise equipment.

In particular, in recent years, home training devices that allow users to exercise at home without visiting a fitness center have been widely used. However, since the previously exemplified devices for strength training have a very large volume and require a lot of installation space, there is a problem in that they are difficult to be used as home training devices.

In order to solve this, technologies for reducing the volume of the exercise equipment when not in use by folding or rotating a part of the exercise equipment are being developed. For example, US Patent Publication US2020/0047027 (Prior Patent 1) and US2019/0262652 (Prior Patent 2) disclose a structure that can be folded when not in use by rotating a part of the exercise device.

The above-described prior art can provide various angles of motion while changing the height of a component such as an arm structure. However, in order to change the height of the exercise device as described above, in the case of Prior Patent 1, a large rotation radius is required because the entire arm 206 must be rotated, and in Prior Patent 2, the height of the slider 403 is fixed with a lock pin. The disadvantage is that the structure is very complicated.

Of course, techniques of a simple method of fixing the exercise equipment to be lifted along the height adjustment pole with pins are also used. However, for home training equipment, the height adjustment pole is often rotatable for a folding structure, and for this purpose, the height adjustment pole is made into a cylindrical structure. There is a disadvantage in that it is not easy to insert the pin into the fixing hole accurately.

US Patent Publication US2020/0047027 (Prior Patent 1) US Patent Publication US2019/0262652 (Prior Patent 2)

The present invention is to solve the problems of the prior art as described above, and an object of the present invention is that the arm system (handle device) of the exercise equipment can be easily fitted into the height fixing hole while ascending and descending along a predetermined path of the height adjustment column. is to be

Another object of the present invention is to enable the arm system to move up and down along another path even when the arm system rotates relative to the height adjusting column.

And a height adjustment rod may be installed on the side frame. A flat portion and a curved portion are continuously disposed on the height adjustment rod in a circumferential direction of a cross section, and a plurality of fixing holes may be formed in the flat portion. The handle device may be raised and lowered along the height adjusting rod, and a fixing pin of the handle device may be inserted into any one of the fixing holes to be fixed in height. Accordingly, the handle device can be raised and lowered along a certain elevating path (planar portion) formed on the height adjusting column, and when the handle device is elevating, the direction is not changed or arbitrarily rotated, and the handle device can be elevated along a constant path.

In addition, the flat portion and the curved portion may extend along a height direction of the height adjustment rod, respectively, a plurality of the flat portions may be disposed on the height adjustment rod, and the curved portion may be disposed between the flat portions. . Accordingly, the handle device can be rotated relative to the height adjustment rod in surface contact with the curved portion.

In addition, the flat portions may be arranged at regular intervals from each other along the circumferential direction of the cross section of the height adjustment rod, and the height of the fixing hole formed in the first flat portion constituting the flat portion, and the first flat portion adjacent to the The height of the fixing hole formed in the second planar portion may be different from each other. In this way, the height interval of each fixing hole is closely arranged, so that it is possible to adjust the height of the handle device more precisely.

In addition, the flat portion may be depressed toward the center of the height control rod than the curved portion, and the left and right widths of the flat portion may be greater than or equal to the width of the front portion of the fixing pin in close contact with the flat portion. Accordingly, the fixing pin can move along a predetermined path without departing from the outside of the planar part.

In addition, a plurality of the curved surface portions are disposed on the height adjustment rod, and the curved surface portions may each constitute a portion of a circular shape having a center of a cross section of the height adjustment rod as a center of a circle. Therefore, the handle device can be smoothly rotated while the height adjusting rod is wrapped.

In addition, the handle device may include a connection body that surrounds the height adjustment rod and is rotatable relative to the height adjustment rod. A handle bar is coupled to the connection body, and the handle bar may stand parallel to the connection body or rotate in a direction perpendicular to the connection body. In this case, a fixing pin may be disposed on the connection body, and the fixing pin may be inserted into the fixing hole while moving in a straight line in the direction of the flat portion.

In addition, the fixing pin may include a fixing lever exposed to the outside and a pin body connected to the fixing lever, and the pin body may be inserted into the fixing hole. In addition, the fixing pin may be provided with a fixing spring that provides an elastic force to the pin body in the direction of the flat portion.

In addition, the handle device may be provided with a bar locking device for hanging a portion of the handle bar to maintain a state in which the handle bar is rotated in a direction perpendicular to the connection body.

The exercise equipment according to the present invention as salvaged above has the following effects.

In the present invention, the handle device of the exercise device can be adjusted in height while ascending and descending along the height adjusting column, and the handle device can be raised and lowered along a certain elevating path (planar part) formed on the height adjusting column. When the handle device is raised and lowered, the direction is not changed or arbitrarily rotated, but it goes up and down along a predetermined path, so that the fixing pin of the handle device can be easily fitted into the fixing hole, and thus the convenience of use of the exercise device is improved.

And, in the present invention, a plurality of elevating paths (planar parts) may be arranged around the outer circumferential surface of the height adjustment column. Accordingly, when the handle device is rotated relative to the height adjusting column, it can ascend and descend along another ascending and descending path. Since the handle device can have a variety of relative angles with respect to the height adjustment pole, the user has the effect of being able to exercise at more various angles.

In addition, in the present invention, the flat portion and the curved portion are continuously arranged along the circumferential direction of the height adjustment column. The curved part makes the rotation of the handle device smooth, and the flat part can make a constant elevating path of the fixing pin. Therefore, even if the handle device is rotated relative to the height adjusting column, the fixing pin for high fixing can always be easily inserted into the fixing hole.

Further, in the present invention, fixing holes are respectively disposed on two different planar parts, and the fixing holes may be disposed at different heights from the fixing holes of other adjacent planar parts. In this way, the spacing of the entire fixing holes can be arranged closely, and thus, there is an effect that the height of the handle device can be adjusted more precisely.

In addition, in the present invention, the flat portion of the height adjustment column may be in a shape recessed toward the center of the height adjustment rod. Since the fixing pin is raised and lowered in the recessed flat portion, it can be stably moved along a predetermined path without departing from the outside of the flat portion. Therefore, there is an effect that the operability of the exercise equipment is improved.

And, since the fixing pin in the present invention protrudes in the same direction as the handle device, the user can easily manipulate the fixing pin. At the same time, since the fixing pin is located at the lower part of the handle device, the portion exposed to the outside by the fixing pin is covered by the handle device is reduced, and thus, there is an effect of improving the aesthetics of the exercise device.

The present invention relates to an exercise device, and the present invention relates to a type of exercise device in which a plurality of parts can be varied. Here, the variable may mean that the overall shape of the exercise device is changed while some parts are rotated or slidably operated. Through this variable structure, the user can fold and store the exercise equipment, and can use the exercise equipment at various angles, lengths or heights.

The exercise device of the present invention includes a handle device 100 , and the handle device 100 can be adjusted in height while ascending and descending along the height adjusting rod 40 . A user may fix the handle device 100 to a desired height and perform an exercise using the handle device 100 . Hereinafter, the structure of the present invention will be described with a focus on the lifting and fixing structure of the handle device 100 .

1 and 2 show an embodiment of an exercise device according to the present invention. 1 shows a state in which the side frames 30A and 30B constituting the exercise equipment are accommodated in the main frame 10 , and in FIG. 2 , the side frames 30A and 30B are drawn out from the main frame 10 . is shown.

The main frame 10 is fixed to an installation place, and the side frames 30A and 30B can be drawn out by linear movement from the main frame 10 . In addition, the side frames 30A and 30B may rotate while being drawn out from the main frame 10 . Therefore, when the user uses the exercise equipment (i) the side frames 30A and 30B must be fixed so as not to move linearly in the direction accommodated in the main frame 10, and (ii) the side frames 30A and 30B ) should be fixed so as not to rotate with respect to the main frame 10 . The rotation operation of the side frames 30A and 30B may be locked by a frame locking device 50 to be described below.

For reference, in the following, 'locked' means that the side frames 30A and 30B or the handle device 100 is fixed so as not to rotate or lift, and 'unlock' means the side frames 30A and 30B or the handle device 100. ) means that it is in a state where it can rotate or ascend and descend.

The main frame 10 may be fixed to the wall (W). In FIG. 1 , it can be seen that the main frame 10 is installed at the corner of the wall W. As shown in FIG. An upper plate 11 and a lower plate 13 may be disposed on the upper and lower portions of the main frame 10 , respectively. The upper plate 11 and the lower plate 13 have a plate-like structure, and a front plate 12 may be provided therebetween.

Here, the front plate 12 is a portion facing the user, and may be configured as a mirror or the display 17 may be installed on the front plate 12 . In this embodiment, a display 17 is provided on the upper portion of the front plate 12 to provide various screens to the user.

In this embodiment, the main frame 10 may have a shape having an installation space therein. For example, as shown in FIGS. 1 and 2 , the main frame 10 may have a triangular prism shape having a cross section in the form of a right isosceles triangle. The main frame 10 may be disposed such that a portion forming a right angle in an isosceles right triangle is located at the rear. When arranging the exercise equipment in the indoor space, if the rear surface of the main frame 10 is positioned at the corner of the installation place, the usability of the space can be increased.

Various parts may be embedded in the installation space of the main frame 10 . Accordingly, the main frame 10 may be viewed as a body portion of the exercise device. Heavy parts are built in the installation space, and the main frame 10 may serve as a center of gravity so that the exercise equipment does not fall. For example, a driving unit (not shown) for generating an exercise load may be included in the main frame 10 . The driving unit may include parts such as a motor, a speed reducer, and a pulley for transmitting a motion load of the driving unit. Since the motor, the reducer and the pulley are mainly made of metal and have relatively heavy weight, they may be disposed inside the main frame 10 to serve as a center of gravity.

As shown in FIG. 2 , a fixed foot 14 may be provided at a lower portion of the main frame 10 . The fixing foot 14 may protrude downward from the lower plate 13 , that is, toward the installation surface. Accordingly, the fixed foot 14 may support the exercise device. The fixed foot 14 may be configured as a leveler, and the height at which the fixed foot 14 protrudes toward the installation surface may be adjusted.

Side frames 30A and 30B may be installed on the main frame 10 . The side frames 30A and 30B may be drawn out or accommodated in the main frame 10 . When the side frames 30A and 30B are accommodated in the main frame 10, the overall volume of the exercise equipment is reduced, thereby reducing the volume occupied by the exercise equipment when not in use. Conversely, when the side frames 30A and 30B are withdrawn from the main frame 10, the length in which the handle device 100 coupled to the side frames 30A and 30B protrudes becomes longer, so that the user can utilize more various exercise functions. have.

In this embodiment, the side frames 30A and 30B may be configured as a pair. That is, the side frames 30A and 30B may include a first side frame 30A and a second side frame 30B. For classification, the left side frames 30A and 30B will be referred to as a first side frame 30A and the right side frames 30A and 30B will be referred to as a second side frame 30B, based on the drawings.

The first side frame 30A and the second side frame 30B may be arranged to be accommodated in or withdrawn from the main frame 10 . The first side frame 30A and the second side frame 30B may be disposed to be symmetrical on both sides with respect to the main frame 10 . As described above, since the first side frame 30A and the second side frame 30B have substantially the same configuration, the following description will be made based on the first side frame 30A.

The first side frame 30A may be accommodated or protruded while sliding along the left side of the main frame 10 . For example, as shown in FIG. 1 , the first side frame 30A may be accommodated in the installation space of the main frame 10 . Conversely, as shown in FIG. 2 , the first side frame 30A may protrude from the left side of the front side of the main frame 10 in a diagonal direction. Although not shown, the first side frame 30A may slide along the LM guide installed inside the main frame 10 .

In this embodiment, the first side frame 30A and the second side frame 30B may protrude from the main frame 10 and then rotate with the vertical direction of the main frame 10 as a rotation axis. For example, as shown in FIG. 2 , the first side frame 30A and the second side frame 30B protruding from the main frame 10 may rotate to approach each other. And by rotating the first side frame 30A to be closer to the second side frame 30B, the user can adjust the handle device 100 of the first side frame 30A and the second side frame according to the user's body structure. The handle device 100 of the 30B may be brought closer to each other.

Looking at the structure of the first side frame 30A, an upper body 31a may be disposed on an upper portion of the first side frame 30A, and a lower body 31b may be disposed on a lower portion of the first side frame 30A. The upper body 31a and the lower body 31b may protrude in parallel with each other at different heights. In this case, the upper body 31a may be a part of a pull-up bar through which a user can exercise such as a pull-up.

The upper body 31a and the lower body 31b may be connected so that the first side frame 30A has a substantially rectangular shape. Here, between the front ends of the upper body (31a) and the lower body (31b) may be connected by a height adjustment rod 40 to be described below, and between the rear ends of the shaft portion ( not shown) can be connected. In addition, between the upper body 31a and the lower body 31b, an installation plate 35 (refer to FIG. 3) on which a mirror or the like is installed may be installed.

Although not shown, in an embodiment of the present invention, a locking means is provided to prevent the first side frame 30A from sliding back into the main frame 10 . For example, the locking means may be configured as a latch that slides vertically on the first side frame 30A to prevent the sliding movement of the first side frame 30A. Alternatively, the locking means may be omitted, and the frame locking device 50 to be described below may limit not only the rotation of the first side frame 30A but also the sliding movement.

A handle device 100 may be installed in each of the first side frame 30A and the second side frame 30B. The handle device 100 may be a portion that protrudes toward the user when the user exercises. The handle device 100 includes a connection body 101 for fixing the handle device 100 to the height adjustment rod 40 of the first side frame 30A, and the height by the connection body 101 . It may include a handle bar 110 fixed to the control rod (40). The specific structure of the handle device 100 will be described again below.

Meanwhile, a wire (not shown) may be embedded in the handlebar 110 , and a gripper (not shown) may be connected to one end of the wire. When the user pulls the gripper, the wire connected to the gripper extends from the inside of the handlebar 110 to the outside, and when the user removes the force pulling the gripper, the gripper and the wire are again connected to the handlebar ( 110) can be returned to the end.

The return of the wire may be made by a load supply unit installed in the main frame 10 . The load supply unit may include a motor and a speed reducer, and may supply a load to the wire in a direction in which the wire is inserted into the original position, that is, the handlebar 110 .

Then, the wire passes continuously through the main frame 10, the first side frame 30A, and the inside of the handle bar 110, one end is connected to the gripper and the other end is wound on the load supply unit. can At this time, a plurality of pulleys 123 (refer to FIG. 4 ) are disposed inside the main frame 10, the first side frame 30A, and the handlebar 110 so that the wire can be stably unwound or wound. have. Alternatively, all or part of the wire may be installed to be exposed to the outside of the exercise device.

Referring to FIG. 2 , the height adjustment rod 40 is vertically erected at the front ends of the first side frame 30A and the second side frame 30B, and the height adjustment rod 40 has the handle device described above. (100) may be installed. That is, the connection body 101 of the handle device 100 is coupled to the height adjustment rod 40 , and when the connection body 101 moves up and down along the height adjustment rod 40 , the handle apparatus 100 . height can be varied.

First, looking at the structure of the height adjustment rod 40, the height adjustment rod 40 may be in the form of a hollow pipe. The wire described above may be accommodated in the inner space 43 of the height adjustment rod 40 . The height adjustment rod 40 may be a shaft for adjusting the height of the handle device 100 .

Looking at the height adjustment rod 40 installed on the first side frame 30A, the height adjustment rod 40 has upper and lower ends of the upper body 31a and the lower body 31b of the first side frame 30A, respectively. ), which are fixed to each other, and may be in a rotatable state. Therefore, the height adjustment rod 40 can be rotated with a rotation shaft formed in the erected direction, that is, in the height direction. Here, the height direction may be a vertical direction when viewed with reference to the drawing.

When the height adjustment rod 40 rotates, the handle device 100 installed on the height adjustment rod 40 also rotates together to create various movement angles. However, after the handle device 100 is rotated to a movement angle desired by the user, it needs to be locked. Such locking may be accomplished by the fixing pin 130 or by a separate locking means.

4 and 5, the structure of the height adjustment rod 40 is shown in detail. The height adjustment rod 40 may extend long in a direction in which it is erected. Here, the erected direction is an up-down direction based on the drawing, and it can also be seen as a direction of gravity. In addition, the height adjustment rod 40 may be installed between the upper body 31a and the lower body 31b in the height direction of the height adjustment rod 40 .

A flat portion 42 and a curved portion 41 may be continuously disposed on the height adjustment rod 40 in the circumferential direction of the cross section of the height adjustment rod 40 . In addition, a plurality of fixing holes 45 may be formed in the flat portion 42 . A pin body 135 of a fixing pin 130 to be described below is inserted into the fixing hole 45 so that the fixing pin 130 can be caught.

Looking more specifically with reference to FIG. 5 , an inner space 43 penetrating in the vertical direction may be formed in the height adjusting rod 40 . Although not shown, a fixing module for preventing rotation of the height adjustment rod 40 may be installed in the inner space 43 of the height adjustment rod 40 . The inner space 43 of the height adjustment rod 40 extends along the vertical direction of the height adjustment rod 40, and therefore, the upper end and the lower end of the height adjustment rod 40 may be in an open state, respectively.

A curved portion 41 and a flat portion 42 may be disposed on the surface of the height adjustment rod 40 . The curved portion 41 may have an arc shape having a predetermined radius. In addition, the flat portion 42 may be disposed adjacent to the curved portion 41 and may have a planar structure. (i) the curved portion 41 may allow the connection body 101 of the handle device 100 surrounding the height adjustment rod 40 to smoothly rotate relative to the height adjustment rod 40 and (ii) the flat portion 42 may be a path through which the pin body 135 of the fixing pin 130 is lifted.

The curved portion 41 and the flat portion 42 may each extend continuously along the height direction of the height adjustment rod 40 . Accordingly, except for the fixing hole 45 , the cross-sectional shape of the height adjustment rod 40 may be the same along the longitudinal direction of the height adjustment rod 40 . Since the curved portion 41 is continuously formed along the longitudinal direction of the height adjustment rod 40, the connection body 101 can rotate smoothly while making surface contact with the curved portion 41 at any height. . In addition, the pin body 135 may be moved along a predetermined path by the flat portion 42 .

In this embodiment, a plurality of the flat portions 42 may be disposed on the height adjusting rod 40 , and the curved portion 41 may be disposed between the flat portions 42 . 5 and 6 , the curved portion 41 may include a first curved portion 41a, a second curved portion 41b, and a third curved portion 41c, and the flat portion 42 may be composed of a first flat portion 42a, a second flat portion 42b, and a third flat portion 42c. And, they may be alternately arranged with each other.

Referring to FIG. 6 , the flat portion 42 may be viewed as a portion formed by omitting a portion of the curved portion 41 . That is, the line A of FIG. 6 is an imaginary curve connecting the first curved portion 41a and the third curved portion 41c, and the third flat portion 42c is formed at a position recessed inward of the A line. can be Accordingly, it can be seen that the flat portion 42 is formed by being depressed between the curved portions 41 .

In other words, a plurality of the curved portions 41 are disposed on the height adjustment rod 40 , and the curved portions 41 have a circular shape with the center of the cross section of the height adjustment rod 40 as the center of a circle. It can be seen that each constitutes

Accordingly, as shown in FIG. 6 , the flat portion 42 may have a structure that is relatively depressed toward the center of the height adjustment rod 40 than the curved portion 41 . When the flat portion 42 has a recessed structure than the adjacent curved portion 41 , the pin body 135 of the fixing pin 130 does not deviate from the flat portion 42 , and the flat portion 42 . It can be stably ascended and descended along a certain path formed by the

The flat portions 42 may be arranged at regular intervals from each other along the circumferential direction of the cross-section of the height adjustment rod 40 . For example, the flat portions 42 may be arranged at intervals of 90 degrees with respect to the center of the cross-section of the height adjustment rod 40 . Alternatively, the flat portions 42 may be arranged at intervals of 30 degrees or 60 degrees based on the center of the cross-section of the height adjustment rod 40 . When the planar parts 42 are arranged at regular intervals, the extending direction of the handle device 100 may also be constantly changed.

In the present embodiment, the curved portion 41 and the flat portion 42 are each composed of three, but unlike this, the number of the curved portion 41 and the flat portion 42 may be two or less or four or more. . For example, referring to FIG. 7 , the curved portion 41 includes first to fourth curved portions 41a to 41d, and the flat portion 42 is also the first to fourth flat portions. (42b~42d) can be seen.

Alternatively, although not shown, the surface of the height control rod 40 may be composed of only the flat portions 42 omitting the curved portion 41 . When the plurality of flat portions 42 are continuously connected to each other, the cross-section of the height adjustment rod 40 may be a polygonal shape.

The left and right widths of the flat portion 42 may be greater than or equal to the width of the front portion of the pin body 135 of the fixing pin 130 in close contact with the flat portion 42 . In this way, the front portion of the pin body 135 can be stably raised and lowered along the flat portion 42 without departing from the inside of the flat portion 42 . Fixing holes 45 may be formed in the flat portion 42 . The fixing hole 45 may have a hole structure formed through the flat portion 42 . In this embodiment, the fixing hole 45 may be a circular hole formed in the flat portion 42, or a hole of various shapes, or a structure in which the surface of the flat portion 42 is recessed instead of a hole. .

A plurality of the fixing holes 45 may be disposed along the planar portion 42 . The height of the handle device 100 may be determined according to which fixing hole 45 among the fixing holes 45 is inserted into the pin body 135 of the handle device 100 .

At this time, the height of the fixing hole 45 formed in the first flat portion 42a constituting the flat portion 42 and the fixing formed in the third flat portion 42c adjacent to the first flat portion 42a The height of the hole 45 may be different from each other. Referring to FIG. 5 , it can be seen that the fixing holes 45 formed in the first flat portion 42a and the fixing holes 45 formed in the third flat portion 42c have different heights from each other. Also, referring to FIG. 8 , the height of the fixing hole 45 formed in the first planar part 42a constituting the planar parts 42 and the third planar part adjacent to the second planar part 42b The height of the fixing hole 45 formed in the 42c may be different from each other.

When the handle device 100 is rotated in the Y direction of FIG. 15(c), the handle device 100 may be unfolded and fixed in that state. Fixing the handle device 100 in an unfolded state may be accomplished by the bar locking device 150 described above.

When the handlebar 110 is rotated and unfolded in the unfolding direction (Y direction), it may be in a state as shown in FIG. 13 . That is, the locking pin 155 of the bar locking device 150 may be inserted into the locking hole 118a of the locking block 118 . Accordingly, the handlebar 110 cannot arbitrarily return from the unfolded state to the folded state. When the user pulls the lock lever 151 while overcoming the elastic force of the lock spring 157, the lock pin 155 comes out of the lock hole 118a. In this state, when the handle bar 110 is rotated, the handle The bar 110 may be in a folded state. For reference, when the handlebar 110 is rotated in an unfolded state, even if the user does not pull the lock lever 151 , the lock pin 155 passes through the lock hole 118a through the curved shape of the lock pin 155 . ) can be incorporated naturally.
