Description

Sports Equipment

The present invention relates to sports equipment and, more particularly, to a sports apparatus that allows a user to perform leg movements.

Figure 1 shows a sports equipment (90) disclosed in U.S. Patent No. 9,199,115, which is incorporated herein by the utility of the utility of the utility of Push and pull the hand movements alternately. In order to provide the aforementioned leg movement, the aforementioned sports equipment (90) mainly comprises a crank mechanism (91), two left and right guide rails (92) (note: the two are parallel and parallel, only the left side rail is shown in the figure), left and right The reciprocating member (93), the left and right two rollers (94), and the left and right two pedals (95), wherein each of the guide rails (92) is a tilting straight rod with a front elevation angle of about 60 degrees, and the crank mechanism (91) is disposed at Above the guide rail (92), the top end of each reciprocating member (93) is pivotally connected to the outer end of the corresponding crank arm (911) of the crank mechanism (91), and the bottom end of each reciprocating member (93) is bent backward and extended, and is bent. The roller (94), which is rollably displaceable on the corresponding rail (92), is disposed in front of the folding portion such that a circular path (CP) guided by the top end of the shuttle (93) along the crank arm (911) During the cyclic movement, the portion of the reciprocating member (93) at which the roller (94) is mounted along the guide rail (92) is guided by a reciprocating track (RP) at the first upper end (E1) and the lower rear side. Reciprocating movement between the second end points (E2); the pedals (95) for supporting the user's feet are fixed behind the bent portions of the respective reciprocating members (93), and based on the above structure, the left and right pedals ( 95) When the force will rise and fall inversely with each other, thereby available for users to carry out the aforementioned leg movement.

Observing the above structure of the foregoing exercise equipment (90), the displacement of the pedal (95) (especially the tip of the foot closer to the roller (94)) during movement is substantially equal to the first end point of the reciprocating trajectory (RP). (E1) The distance from the second end point (E2), that is, approximately equal to the diameter of the aforementioned circular trajectory (CP). On the other hand, since the pedal (95) is fixed to the aforementioned reciprocating member (93), in the movement, as the relative angles of the top and bottom ends of the reciprocating member (93) exhibit periodic changes, the pedal (95) is in front, The relative angles of the latter two ends also exhibit corresponding periodic changes, such as on the pedal (95) as a whole. During the ascent, the heel end is deflected to a maximum height relative to the tip of the foot, and during the overall lowering of the pedal (95), the heel end is deflected to a minimum height relative to the tip of the foot with an angular difference equal to the shuttle ( 93) the magnitude of the change of the angle of the top end with respect to the bottom end, and the aforementioned angle change angle is also increased or decreased according to the size of the circular track (CP), in other words, when the circular track (CP) is larger, the aforementioned maximum height The higher the height, the lower the minimum height will be, and the larger the angle difference will be.

Based on the above-described features of the aforementioned exercise equipment (90), if it is desired to provide the aforementioned leg movement with a longer foot stroke and a higher leg height, it is necessary to lengthen the diameter of the circular track (CP), that is, to adopt a longer length. The crank arm (911) is such that the displacement amplitude of the pedal (95) is correspondingly increased. However, the expansion of the circular trajectory (CP) may cause the angle of the pedal (95) to vary, which may cause the user's ankle joint to move too far, and the angle between the calf and the footplate exceeds the ergonomic proper angle. Causes uncomfortable feet and even sports injuries such as muscle ligament pain. On the other hand, if a shorter crank arm (911) is used to suppress the angle variation of the pedal (95) within an appropriate range, the leg stroke and the leg height of the leg movement are relatively short and low, and the movement difficulty is And sports effects are limited. Theoretically, lengthening the distance from the top end of the reciprocating member (93) to the roller (94) can also reduce the angular variation of the reciprocating member (93), but the effect is less obvious, and the longitudinal length of the reciprocating member (93) must be greatly lengthened. A substantial increase in the height of the crank mechanism (91) can make the aforementioned angle difference narrower, so it is not practical. In summary, the structure of the aforementioned sports equipment (90) is difficult to balance both the longer pedaling stroke and the smaller (or appropriate range) range of pedal angle variation.

Based on the above structure of the foregoing exercise equipment (90), in the process in which the pedal (95) rises from the lowest position to the highest position, the tip of the foot follows an oblique trajectory substantially parallel to the aforementioned reciprocating trajectory (RP) (not shown) Shift) is displaced upwards and upwards, and in the first half of the ascending stroke, the heel end is significantly raised relative to the tip of the foot; during the step in which the pedal (95) is lowered from the highest position to the lowest position, the tip of the foot is again substantially along the aforementioned oblique The trajectory is displaced backwards and downwards, and in the first half of the descending stroke, the heel end is significantly lowered relative to the tip of the foot. At least on one foot, the above-mentioned leg movements are similar to the steps of the original step, that is, the strength of the thighs is used to lift the knees so that the calves and the feet naturally rise (note: when the footsteps are raised, the raised feet will Slightly advancing the foot of the ground, not vertically rising, and then directly lowering the thigh to return the foot to its original position. This kind of leg movement is slightly monotonous, the foot is raised upwards and the lower step is generally along the same route, and there is no movement of the calf to step forward and backward, the leg movement is less comprehensive and the amount of exercise is insufficient.

In addition, ideally we would like to have the most ergonomic angle of the pedal at each position on its trajectory during such leg movements, making the foot most natural and comfortable during exercise. However, based on the above-described structure of the aforementioned exercise equipment (90), when the pedal (95) reciprocates, the heel end rises relative to the tip of the foot, and when it is lowered, completely following the reciprocating member (93) during the movement period. The angle change behavior, and the aforementioned angle change behavior is basically determined by the relative relationship between the circular trajectory (CP) and the aforementioned reciprocating trajectory (RP), and the design can be adjusted by adjusting relevant parameters (such as the crank arm (911) and The ratio of the length of the reciprocating member (93), the inclination and position of the guide rail (92), etc., to change the aforementioned angular change behavior, but the parameters are limited by the basic structure and spatial configuration of the aforementioned sports equipment (90) and cannot be greatly changed. And the results obtained are usually lost, so it is difficult to optimize the angle change behavior of the pedal (95).

The aforementioned sports equipment (90) also has a problem in use: when the user leaves the exercise equipment (90) after the end of the exercise, it is normally necessary that one of the pedals (95) is substantially at the lowest position and the other pedal ( 95) It is roughly at the highest position. Therefore, the next time the next user wants to use it, it is natural to first step the corresponding foot on the pedal (95) at the lower position, and then lift the other foot to the knee. High step on the pedal (95) at the height, then the higher one presses the pressure to lower the pedal (95) on the side, and the pedal (95) on the other side rises accordingly, so start Left and right two pedals (95) alternately move up and down; before starting the exercise, the left and right two pedals (95) are respectively located near the highest position and the lowest position, equal to the left and right two rollers (94) respectively located in the aforementioned reciprocating The first end point (E1) and the second end point (E2) of the trajectory (RP) are near, and at the same time, the top ends of the left and right reciprocating members (93) are respectively located on the circular track (CP). Near the point (D1) and the second dead point (D2) (Note: in the side view, the first dead point (D1), the center of the circular path (CP) (O) and the first end point (E1) three points even In a straight line, in addition, the center (O), the second dead point (D2), and the second end point (E2) of the circular path (CP) are connected in a straight line. In short, the components are disadvantageous. The position of the start; in addition, when the user first steps on the pedal (95) at the lower position, the reciprocating member (93) on the side forms a torque with the roller (94) as a fulcrum, and the aforementioned torque is usually The top end of the reciprocating member (93) is displaced along the circular trajectory (CP) by a small distance from the vicinity of the second dead point (D2) in the counterclockwise direction (according to the perspective of FIG. 1, the same below), so that the left and right sides are The top ends of the reciprocating members (93) are respectively located at the opposite sides of the first dead point (D1) and the second dead point (D2) in the counterclockwise direction, and then, when the user presses the other foot to press the pedal located at a high position ( 95), the direction of action of the force causes the top end of the reciprocating member (93) to rotate in a clockwise direction along the circular path (CP), that is, when the user first presses the pressing pedal (95), each The top end of the shuttle (93) must first follow a circular path (CP) The rewinding is continued after approaching and passing the dead point (D1) (D2) next to it, while the roller (94) at the upper position is slightly moved up to the first end (E1) of the reciprocating trajectory (RP). It starts to fall, and the roller (94) at the lower position starts to rise slightly after moving down to the second end point (E2) of the reciprocating track (RP), so it will be slightly stuck and laborious at startup.

As shown in FIG. 1, the upper half of the sports equipment (90) further has left and right two handles (96) that can be reciprocally oscillated, and the two handles (96) are connected to the crank mechanism (91) via a linkage mechanism (97). Transmission connection (Note: only the part is shown in the figure, the detailed structure and the operation principle can be referred to the patent No. 9,199,115 of the former US), so that the swing of the left and right two handles (96) and the lifting of the left and right two pedals (95) are The predetermined manners are interlocked with each other, whereby the user can perform hand movements in which the hands of the aforementioned leg movements are alternately pushed and pulled. The structure of the linkage mechanism (97) is complicated and costly.

The main object of the present invention is to provide a sports equipment for the user to alternately raise the legs and lower the leg movements, and the length of the foot movement and the foot angle in the aforementioned leg movements. The magnitude of the change is not necessarily related. In other words, the aforementioned sports equipment can be designed to provide the aforementioned leg movements in which the foot stroke is long and the leg height is high, while the angle of the foot angle is controlled to be within an appropriate range.

Another object of the present invention is to provide a sports equipment for the user to alternately raise the legs and lower the leg movements, and the aforementioned sports equipment is relatively easy to design for the foot angle during exercise. The behavior of change is optimized.

It is still another object of the present invention to provide a sports apparatus that allows a user to alternately raise the feet up and down the lower leg movements, and the leg movements include the lower legs forward and backward retracted. Action, exercise is more comprehensive, and the amount of exercise is more.

Another object of the present invention is to provide a sports equipment for the user to alternately raise the legs and lower the leg movements, and the sports equipment can be designed to improve the leg movement according to requirements. The ground simulates the movement of the foot and the change of the angle of the foot when the human body steps on the step.

It is still another object of the present invention to provide a sports apparatus that allows a user to alternately raise the legs and lower the leg movements downward, and each time the user starts to perform the aforementioned leg movements, Naturally and labor-savingly, the members are moved from the initial position to the predetermined direction.

Another object of the present invention is to provide a sports equipment for the user to alternately raise the legs and lower the leg movements, and also to selectively engage the user with the aforementioned leg movements. The hand movement of the hand is pushed and pulled alternately, wherein the linkage mechanism between the hand movement and the leg movement is relatively simple and the cost is low.

In order to achieve at least the foregoing disclosure, the sports equipment provided by the present invention comprises a frame body, a second linking member and a second driving member, wherein a first portion and a second portion of each of the linking members are respectively replaced by a frame on the frame body a guiding mechanism and a second guiding mechanism are guided to move on a circular trajectory and a reciprocating trajectory, and the first portion of the two linking members are kept opposite on the circular trajectory, when the first linking member is When the portion is circulated along the circular path, the second portion of the linking member reciprocates between the first end point and the second end point of the reciprocating track, and a third portion of the linking member is along the first a closed track cyclic motion, wherein the first portion of each of the linking members is kept higher than the second portion and the third portion, the reciprocating track is entirely below the lowest point of the circular track, and the first end point and The sharp angle between the connecting line of the second end point and the horizontal plane is greater than 45 degrees; a pivoting portion of each of the driving members is pivotally connected with the third portion of the corresponding linking member, and together along the first closed rail Moving, a restricting portion of each of the driving members is guided by a third guiding mechanism on the frame body to move on a limiting track, such that the position of the pivoting portion on the first closed track determines the restricting portion. a position on the restricting trajectory, thereby determining an angle and a position of a supporting portion on the linking member relative to the frame body, and when the pivoting portion is circulated along the first closed trajectory, the supporting portion is along a second closed trajectory cyclic motion; the second closed trajectory is entirely below the lowest point of the circular trajectory, and the difference between the highest position and the lowest position projection on the second closed trajectory in the upper and lower axial directions is greater than the foregoing The front and rear positions on the second closed trajectory are projected in front and rear axial gaps in the front and rear axial directions.

Thereby, the user can step on the support portions of the two-clamping member respectively, and appropriately apply a force to make the support portions circulate along the second closed trajectory (ie, along the half-track of the middle side, along the trajectory The other half of the trajectory is lowered, so that the legs are alternately raised upwards and the lower leg movements are depressed. Wherein, the upward movement of the foot and the downward depression are movement along different paths having a front-rear gap, and the leg movement can include the calf forward and backward retracted by the appropriate shape of the second closed trajectory. action.

Moreover, because the aforementioned limited trajectory and the aforementioned first closed trajectory can be designed The relative relationship determines the angle change behavior and the angle change angle of the driving member in the motion cycle, which is not necessarily related to the angle change behavior and the lifting displacement amplitude of the linkage member in the motion cycle, so the present invention can take care of the longer foot. The range of motion of the part and the smaller (or appropriate range) of the angle of the foot, and it is easier to optimize the angle change behavior of the foot. For example, by appropriately setting the aforementioned restriction trajectory, the magnitude of change in the relative angle between the tip end and the heel end of the support portion can be made smaller than the magnitude of change in the relative angle between the first portion and the second portion of the linkage.

According to a preferred embodiment of the present invention, the second closed trajectory is divided into a first half opposite to the upper rear side and a second half opposite the front lower side; when the foregoing supporting portion is in the second closed trajectory When the top of the first and second halves distinguish points, the heel end of the support portion is at a first height relative to the tip of the foot; when the support portion distinguishes a point at the bottom of the first and second halves of the second closed trajectory, The heel end of the support portion is located at a second height relative to the tip end of the foot; when the aforementioned support portion is at an intermediate point of the first half, the heel end of the support portion is positioned at a third height relative to the tip of the foot; When the portion is at an intermediate point of the second half, the heel end of the support portion is at a fourth height relative to the tip of the foot; wherein the third height is higher than the second height, and the fourth height is lower than the first height . Thereby, when the user's foot rises along the trajectory of the first half along the trajectory of the first half and decreases along the trajectory of the second half, the heel rises relative to the toe in the first half of the ascending stroke. In the first half of the descent stroke, the heel is lowered relative to the toe, so that the movement is more natural and comfortable.

According to a preferred embodiment of the present invention, the second closed trajectory is divided into a first half opposite to the upper rear side and a second half opposite the front lower side, and the trajectory of the first half is convexly curved. The track length of the second half is shorter than the track length of the first half; during the process in which the support portion rises along the trajectory of the first half, the heel end of the support portion is raised first to the tip of the foot. The maximum height is then lowered; during the process in which the aforementioned support portion descends along the trajectory of the second half, the support portion is substantially horizontal. Thereby, the leg motion preferably simulates a foot movement trajectory and a foot angle change when the human body steps on the step.

According to a preferred embodiment of the present invention, the user's foot pair is in a state in which the two linking members and the two driving members are stationary, and the second portion of the linking member is located at a higher end of the reciprocating track. When the supporting portion of the corresponding driving member is biased downward, the force acts on the linking member via the pivoting portion of the driving member, so that the second portion of the linking member is caused Displaceing from the higher end of the reciprocating trajectory, and the first portion of the linking member is displaced by a predetermined rotation point of the circular trajectory in a predetermined rotational direction. Correspondingly, the supporting portion of the driving member is A top specific point of the second closed trajectory is displaced along a predetermined point from the second half to a bottom. For example, the first dead point is on the front upper quarter arc of the circular trajectory, and the predetermined rotation direction is corresponding to the first dead point being displaced forward and downward along the circular trajectory; The third portion of the linking member is higher than the second portion, and the third portion is located at a front side of the straight line passing through the first portion and the second portion simultaneously in a side view. For example, the first dead point is on the rear upper quarter arc of the circular trajectory, and the predetermined rotation direction corresponds to the first dead point being displaced downward and backward along the circular trajectory; The third portion of the linking member is lower than the second portion, and the third portion is located at a rear side of the straight line passing through the first portion and the second portion simultaneously in a side view. Thereby, when the user wants to start the aforementioned leg movement, one of the feet is naturally stepped on the pedal located at the lower position, and the other foot is stepped on the pedal located at the height and applied downward, that is, It is possible to labor-saving the movement of components such as pedals in a predetermined direction.

According to a preferred embodiment of the present invention, the third guiding mechanism includes two rocking members, each of the rocking members has an axial center portion and a connecting portion, and the axial center portion is pivotally connected to the frame body, and the connecting portion is a pivoting connection with the corresponding limiting portion of the driving member, thereby guiding the restricting portion to reciprocate along the arc-shaped restricting trajectory; further, each of the rocking members has at least one catching portion for the user to grasp, thereby The foregoing sports equipment can be used for the user to selectively perform the hand movement of the two hands alternately pushing and pulling with the aforementioned leg movement, and the structure is relatively simple and the cost is low.

Wherein the first end point (E1) of the reciprocating track (RP1) is higher than the second end point (E2), and the connecting line (L1) of the first end point (E1) and the second end point (E2) ( Referring to Figure 7), the sharp angle between the horizontal plane (e.g., the ground (G)) is greater than 45 degrees. In the preferred embodiment, the first end point (E1) is positioned in the front-rear axial direction than the second end point (E2). ) Relatively forward, specifically, the front elevation angle of the first end point (E1) relative to the second end point (E2) is about 62 degrees.

Further, the aforementioned reciprocating trajectory (RP1) is entirely below the lowest point of the circular trajectory (CP), and is more rearward than the center of the circular trajectory (CP) (ie, the crankshaft (522) axis); 4 and 8, when the bottom end of the linking member (560) is located at the first end point (E1) of the circular path (CP) where the reciprocating track (RP1) is closest to the reciprocating path (RP1), the top end of the linking member (560) Will correspond to a first dead point (D1) on the upper quarter arc of the front of the circular trajectory (CP) (Note: under the side view, the first dead point (D1), circular trajectory (CP) The center of the circle and the first end point (E1) are connected in a straight line; otherwise, as shown in FIG. 2 and FIG. 6, when the bottom end of the linking member (560) is located at the reciprocating path (RP1), the farthest from the circular path. At the aforementioned second end point (E2) of (CP), the top end of the linking member (560) will correspond to a quarter of the lower end of the circular path (CP). A second dead point (D2) on the arc (note: in the side view, the center of the circular trajectory (CP), the second dead point (D2) and the second end point (E2) are connected in parallel. ). Wherein, since the center of the circular trajectory (CP) in the side view, the first end point (E1) of the reciprocating trajectory (RP1), and the second end point (E2) are not collinear, the circular trajectory (CP) The first dead point (D1) and the second dead point (D2) are not exactly 180 degrees, specifically, the connecting line (L1) of the first end point (E1) and the second end point (E2) The upward extension line passes directly below the center of the circular trajectory (CP), and the first dead point (D1) is opposite to the front elevation angle of the center of the circle by about 70 degrees, and the second dead point (D2) is opposite to the foregoing. The rear elevation angle of the center of the circle is approximately 68 degrees. When the top end and the bottom end of the link member (560) on one side are respectively located at the second dead point (D2) and the second end point (E2), respectively, because the left and right crank arms (524) are outside The end is 180 degrees opposite on the circular trajectory (CP), so the top end of the linkage (560) on the other side will correspond to the front and bottom of the first dead point (D1) on the circular trajectory (CP) and adjacent The position of the first dead point (D1), and the bottom end thereof corresponds to a position on the reciprocating track (RP1) that is lower than the first end point (E1) and adjacent to the first end point (E2).

The top end (first portion) and the bottom end (second portion) of the linking member (560) are respectively guided to move on the circular track (CP) and the reciprocating track (RP1) with respect to the frame body (510), Another predetermined portion (third portion) (566) of the linkage (560) is moved relative to the frame (510) to be moved on a first closed trajectory (CP1), in other words, in the aforementioned linkage (560) While the third portion (566) is wound one turn along the first closed trajectory (CP1), the top end of the linking member (560) is rotated around the circular trajectory (CP), and the bottom end is along The reciprocating track (RP1) reciprocates one turn. In the preferred embodiment, the third portion (566) is disposed between the top end and the bottom end of the linking member (560), and in a side view, the third portion (566) is opposite to the top end and the bottom end. The front side of the connecting line. Based on the preset spatial relationship of the components, the rotation of the top end of the linkage (560) along the circular trajectory (CP) and the aforementioned third portion (566) along the first closed trajectory (CP1) The direction of motion of the detours corresponds to each other, for example, when the top end of the linking member (560) moves along the circular path (CP) in the counterclockwise direction in Fig. 2 (i.e., on the semicircular arc on the front side) The movement, moving upward on the semicircular arc on the rear side, the third portion (566) also moves downward in the first half of the first closed trajectory (CP1) and upward in the second half. The first portion (ie, the tip) of the linkage (560) is always maintained higher than the third portion (566) during the cycle of rotation of the top end of the linkage (560) along a circular path (CP). Of course, it is also kept above the aforementioned second portion (ie, the bottom end). The first closed trajectory (CP1) has an elongated elliptical or fusiform shape with a sharp angle between the major axis direction and the horizontal plane greater than 45 degrees. In the preferred embodiment, the first seal The top end of the closed track (CP1) is positioned forward in the front and rear axial directions more than the bottom end. Specifically, the front elevation angle of the top end of the first closed track (CP1) with respect to the bottom end is about 65 degrees.

The aforementioned sports equipment (500) further includes left and right swinging members (570) and left and right second driving members (580) symmetrically arranged. The two rocking members (570) are located on the front upper side of the crank mechanism (520), each having an axial center portion (572) and a connecting portion (574), wherein the axial center portion (572) is corresponding to the left and right axes. The third axis (not shown) is pivotally connected to the front end of the second rod (5142) of the skeleton (514), and the connecting portion (574) is opposite to the rear upper portion of the shaft portion (572), and can be axially (572) Swings up and down the axis. Each of the driving members (580) is substantially an L-shaped bent rod body, and a predetermined portion (hereinafter referred to as a pivoting portion) (582) above the bottom side bending portion is pivotally connected to the corresponding side of the linking member The third portion (566) of (560) is such that the driving member (580) and the linking member (560) of the same side can be relatively deflected by the pivoting portion (582)/third portion (566), and The pivoting portion (582) of the member (580) and the third portion (566) of the linkage (560) move along the first closed trajectory (CP1). Further, a top end (hereinafter referred to as a restricting portion) (584) of each of the driving members (580) is pivotally connected to a connecting portion (574) of the rocking member (570) of the corresponding side, such that the aforementioned restricting portion (584) is opposite to the frame body ( 510) is constrained to move on an arcuate limiting trajectory (RP2) guided by the rocking member (570). On the other hand, the bottom portion of each of the driving members (580) is bent and extended to form a supporting portion for supporting the user's foot and receiving the user's force. The preferred embodiment is provided at the same place for the user. The pedal (590), which is stepped on by one foot, is considered to be part of the aforementioned support portion and has a relatively forward foot tip and a relatively rear heel end. The support portion (including the pedal (590)) of each of the driving members (580) is opposite to the rear of the pivoting portion (582), and is located at substantially the same height as the bottom end of the corresponding linking member (560).

Because the distance between the pivoting portion (582), the restricting portion (584) and the supporting portion (hereinafter represented by the pedal (590)) on the driving member (580) are constant, the preset is based on an appropriate preset. The size and positional relationship of the member, when the pivoting portion (582) of the driving member (580) moves along the first closed trajectory (CP1), the position of the pivoting portion (582) on the first closed trajectory (CP1) is determined. The position of the restricting portion (584) on the restricted trajectory (RP2) determines the position and angle of the pedal (590) relative to the frame (510). When the pivoting portion (582) of the entraining member (580) circulates along the first closed trajectory (CP1), the restricting portion (584) of the entraining member (580) is along the aforementioned arcuate limiting trajectory (RP2) The top end and the bottom end reciprocate, and a predetermined portion of the pedal (590) (exemplified by the center of the pedal in the figure) will circulate along a second closed trajectory (CP2) relative to the frame body (510) (Note: In the following, for example, "the aforementioned predetermined portion of the pedal moves along the second closed trajectory" may simply be expressed as "the pedal along the second closed rail The track motion"), and the angle of the aforementioned heel end relative to the aforementioned foot tip will exhibit a periodic variation. Wherein, the moving direction of the pedal (590) along the second closed trajectory (CP2) corresponds to the moving direction of the pivoting portion (582) of the driving member (580) along the first closed trajectory (CP1). That is, the rotation direction of the top end of the linking member (560) rotating along the circular path (CP) corresponds to each other. The sharp line between the top end and the bottom end of the limiting track (RP2) (L2) (see FIG. 7) and the horizontal plane is greater than 45 degrees. In this embodiment, the front end has an elevation angle of about 49 degrees with respect to the bottom end. .

Further, the aforementioned second closed trajectory (CP2) is entirely under the lowest point of the circular trajectory (), and has an elongated elliptical shape or a fusiform shape. As shown in FIG. 4 and FIG. 8, when the top end and the bottom end of a linking member (560) are respectively located on the circular trajectory (CP), the first dead point (D1) and the first end point of the reciprocating trajectory (RP1) are respectively shown. (E1), the third portion (566) of the linkage (560) and the pivoting portion (582) of the corresponding driver (580) are substantially at the top end of the first closed track (CP1), so that the aforementioned driving The restricting portion (584) of the member (580) is also located substantially at the top end of the limiting trajectory (RP2), and the pedal (590) corresponds to a top specific point (P1) on the second closed trajectory (CP2), the pedal (590) The heel end is at a first height relative to the tip of the foot, in this case a position of about 4 degrees of the rear elevation angle; conversely, as shown in Figures 2 and 6, the top and bottom ends of a linkage (560) When the second dead point (D2) on the circular trajectory (CP) and the second end point (E2) of the reciprocating trajectory (RP1) are respectively located, the third portion (566) of the aforementioned linking member (560) is associated with the corresponding The pivoting portion (582) of the driving member (580) is substantially positioned at the bottom end of the first closed trajectory (CP1) such that the restricting portion (584) of the aforementioned driving member (580) is also substantially positioned at the limiting trajectory (RP2). Bottom end, and the pedal (590) corresponds to the second closed rail The bottom of a specific point (P2) on (CP2 of), the pedal (590) of the heel to the foot end of the tip at a second height position, in this case a substantially horizontal position, lower than the first height. The position of the top specific point (P1) in the front-rear axis is more forward than the bottom specific point (P2), and the joining direction of the two points (P1) (P2) is defined as the long-axis direction of the second closed trajectory (CP2). The sharp angle between the long axis direction and the horizontal plane is greater than 45 degrees, and is about 68 degrees in the preferred embodiment. The second closed trajectory (CP2) has a short axis direction perpendicular to the long axis direction, and the maximum width of the second closed trajectory (CP2) in the short axis direction is smaller than the top specific point (P1) and the bottom specific point (P2) Half the distance of the line. In addition, the height difference between the highest position and the lowest position projection on the second closed trajectory (CP2) in the upper and lower axial directions is greater than the front and rear gaps of the foremost position and the last position projection on the second closed trajectory (), in other words, During the rounding of the pedal (590) along the second closed trajectory (CP2), the difference in the vertical direction of the rise and fall of the pedal (590) may be greater than the horizontal difference between the forward and reverse steps of the pedal ().

As shown in FIG. 10, the second closed trajectory (CP2) is divided into a first half (H1) opposite to the upper rear side and a relatively lower front and lower sides according to the top specific point (P1) and the bottom specific point (P2). The second half (H2), the intermediate point (P3) of the first half (H1) is located rearward in the front-rear direction in the axial direction of the second half (H2). As shown in FIGS. 3 and 7, when the pedal (590) is at the intermediate point (P3) of the first half (H1), the heel end of the pedal (590) is at a third height relative to the tip of the foot. In this example, the position of the rear elevation angle is about 3 degrees, which is higher than the second height; as shown in FIG. 5 and FIG. 9, when the pedal (590) is at the intermediate point (P4) of the second half (H2), The heel end of the pedal (590) is positioned at a fourth height relative to the tip of the foot, in this example a position of about 1 degree of the depression angle below the first height. Thus, when the pedal (590) is moved in a trajectory along the trajectory of the first half (H1) and descends along the trajectory of the second half (H2), it circulates along the second closed trajectory (CP2). At the first half of the ascending stroke, for example, from the aforementioned bottom specific point (P2) to the intermediate point (P3) of the first half (H1), the heel end of the pedal (590) is raised relative to the tip of the foot; Ground, in the first half of the descending stroke, for example, from the aforementioned top specific point (P1) to the intermediate point (P4) of the aforementioned second half (H2), the heel end of the pedal (590) is lowered relative to the tip of the foot. In the present invention, the difference in the third height from the second height and/or the difference in the fourth height from the first height may be more apparent by appropriately presetting the spatial relationship of the members.

Because in the side view, the top ends of the left and right two links (560) are 180 degrees opposite on the circular track (CP), the pivoting portions (582) of the left and right two-clamping members (580) are first. The closed track (CP1) is also substantially maintained in the relative position, and correspondingly, the left and right pedals (590) are also substantially maintained in the relative position on the second closed track (CP2), for example, when one of the pedals (590) is located. At the top/bottom end of the second closed trajectory (CP2), the other pedal (590) will be positioned substantially at the opposite bottom/tip, and it is assumed that the top end of the linkage (560) is the inverse clock of Figure 2. The direction is rotated on a circular path (CP), then, roughly speaking, when one of the pedals (590) moves forward along the first half (H1) of the second closed track (CP2), the other The pedal (590) will move rearward and downward along the second half (H2) of the second closed track (CP2).

When using the aforementioned exercise equipment (500), the user steps his feet on the left and right pedals (590), respectively, and grips his hands on the top of the third rod (5143) of the skeleton (514). On the left and right grips (516), the left and right pedals (590) are alternately stepped on by the two legs, so that the left and right pedals (590) remain relatively along the second closed track (CP2). Circulating movement This is done by alternately raising the feet up and down the lower leg movement.

According to one aspect of the present invention, the crank mechanism (520) of the prior preferred embodiment forms a first guiding mechanism for guiding the top end (first portion) of the left and right two linking members (560) with respect to The frame body (510) moves along a circular path (CP), and the top ends of the two linking members (560) are kept opposite; the second swing arm (550) forms a second guiding mechanism for guiding the left side, The bottom end (second portion) of the right second linkage (560) moves relative to the frame body (510) along a reciprocating path (RP1); the two rocking members (570) form a third guiding mechanism for guiding The top end (restriction portion) of the left and right second entraining members (580) moves along a restricted trajectory (RP2) with respect to the frame body (510). In other embodiments of the invention (without corresponding drawings), different types of mechanisms may be used for the same or similar motion trajectory guidance, for example, rails or guide slots may be provided on the frame body (510) to replace the aforementioned pendulum The arm (550) and/or the rocking member (570) are mounted on the second portion of each of the linking members (560) and/or the restricting portion of each of the driving members (580) to be slidable along the rail or the guide groove Roller. The reciprocating trajectory and the limiting trajectory in the present invention may exhibit a straight or non-arc curve, and the aforementioned limiting trajectory may also be closed.

The aforementioned exercise equipment (500) provided by the present invention has several advantages as compared with prior art exercise equipment that can perform similar leg movements, as will be explained below. Firstly, because the relative relationship between the aforementioned limiting trajectory (RP2) and the aforementioned first closed trajectory (CP1) is designed, the angle change behavior and the angular variation range of the driving member (580) during the motion period are determined, and the linkage ( 560) The angle change behavior and the amplitude of the lift displacement during the exercise cycle are not necessarily related, so the aforementioned exercise equipment (500) can take into account the longer pedal (590) travel stroke and the smaller (or appropriate range) pedal (590). The angle varies, and it is easier to optimize the angle change behavior of the pedal (590). In other words, the aforementioned exercise equipment (500) can be designed to provide the aforementioned leg movements in which the foot stroke is long and the leg height is high, while the angle of change of the angle of the foot is controlled within an appropriate range. In the preferred embodiment, the angle of the tip end of the linking member (560) with respect to the bottom end varies by about 19 degrees in a period in which each portion is rotated one turn or reciprocated along its motion path. The angle of change of the angle of the heel end of (590) relative to the tip of the foot is about 4 degrees, which is less than the angular extent of the linkage (560).

When the leg motion is performed using the aforementioned exercise equipment (500), the pedal (590) may be ascending along the first half (H1) of the second closed trajectory (CP2) and descending along the second half (H2). In a way, or by circling along the second half (H2) and descending along the first half (H1), in general, the user's foot is raised upwards and the downward depression is along the front and back gaps. Different roads The linear motion, with the proper shape of the second closed trajectory (CP2), can include the movement of the lower leg forward and backward, and the movement is more comprehensive and the amount of movement is more.

As described above, when the pedal (590) is circulated along the second closed trajectory (CP2), if the direction of the circumscribing is along the trajectory of the first half (H1), along the second half ( The trajectory of H2) is lowered, then in the first half of the ascending stroke, the heel end of the pedal (590) is raised relative to the tip of the foot (eg, raised from the aforementioned second height to the aforementioned third height), and in the first half of the descending stroke In the segment, the heel end of the pedal (590) is lowered relative to the tip of the foot (eg, from the aforementioned first height to the aforementioned fourth height), in other words, when the foot of the user supported by the pedal (590) is at the lowest position of the motion trajectory When starting to lift up, the heel will rise relative to the toe. When the user's foot pushes the pedal (590) down from the highest position, the heel will fall relative to the toe, so the movement is more natural and comfortable. However, since the crank mechanism (520) can be freely rotated in both directions, the user can change the manner of applying the left and right pedals (590) (for example, on the left and right pedals (590). When the height is approximately equal, it is controlled to lower the left foot, the right foot is raised, or the control is to lower the right foot and the left foot is raised, so that the pedal (590) follows the second closed trajectory (CP2) in the opposite bypass direction. The cyclic motion, that is, the trajectory along the second half (H2) rises and descends along the trajectory of the first half (H1).

However, the sports equipment (500) of the prior preferred embodiment is actually designed such that the user naturally drives the pedal (590) to circulate in a predetermined bypass direction, that is, unless the user deliberately controls the application. Force mode, otherwise the pedal (590) will usually rise along the first half (H1) of the second closed trajectory (CP2) and descend along the second half (H2), so that the direction of the circumstance is more natural. The movement mode, and the preset angle and angle change manner of the pedal (590) at various positions are also designed to match the direction of the bypass. In detail, based on the structure of the aforementioned sports equipment (500), when the user leaves the sports equipment (500) after the end of the exercise, it is normally a pedal (590) on one side of the side (here, the left side pedal is Example) is roughly at the lowest position of the second closed trajectory (CP2), and the pedal (590) on the other side (here, the right pedal is taken as an example) is roughly at the highest position, so the next or next user To use it, it is natural to first step the left foot on the left pedal (590) near the lowest position (Note: if the pedal (590) was not previously in the lowest position, this action usually causes the pedal (590) to be further lowered) Then, raise the right foot knee to step on the right pedal (590) near the highest position, then apply pressure to the right foot to lower the right pedal (590), and the left pedal (590) correspondingly rises. So start the movement of the left and right pedals (590) alternately; Before starting the exercise, the left pedal (590) is roughly at the lowest position of the second closed trajectory (CP2), meaning that the top end of the left linkage (560) is located on the lower quarter arc behind the circular trajectory (CP). Near the second dead point (D2), at the same time, the top end of the right linkage (560) will be on the upper quarter arc of the circular trajectory (CP), and the relative position is at the first dead point (D1). The lower front portion; when the higher right foot presses the right pedal (590) downward, the force acts on the third portion of the right linkage (560) via the pivoting portion (582) of the right driving member (580) ( 566), because the third portion (566) is opposite to the front side of the connecting line between the top end and the bottom end of the linking member (560), the downward force acting on the third portion (566) will be the linking member (560). Forming a torsion force that deflects the tip end against the bottom end against the clock such that the bottom end of the right side linkage (560) moves downward along the reciprocating path (RP1) while the tip end along the circular path (CP) Moving counterclockwise forward and downward, corresponding to this, the right pedal (590) will be along the second half of the second specific trajectory (P1) near the top of the second closed trajectory (CP2) (H2) descends, and the left pedal (590) rises along the first half (H1) near the bottom specific point (P2) of the second closed trajectory (CP2), and thereafter, by the aforementioned flywheel (530) or the like The motion inertia and the user's law of force application, the left and right two pedals (590) will circulate along the second closed trajectory (CP2) in such a bypass direction.

As described above, when the movement is to be started from a stationary state, because the top end of the relatively high linkage (560) will directly rotate downward on the circular path (CP) and away from the first dead point (D1) next to it. (rather than rewinding upwards and approaching and passing through the aforementioned dead point (D1)), the bottom end is also directly lowered near the first end point (E1) of the reciprocating trajectory (RP1) (rather than slightly rising to the first end first) The point (E1) is turned down again, so that the user can step on the first step effortlessly and smoothly, and naturally start moving all the members in the predetermined direction.

It must be pointed out here that the starting position and starting action of the components described above are exemplified by typical conditions; in practice, due to mechanical factors (such as friction between components) and human factors (such as the influence of the user on the position of the components), The top end of the relatively high linkage (560) will not always be at a fixed position on the side of the first dead point (D1) in the counterclockwise direction each time the user is about to start moving and is ready to step on the first step. Sometimes it may be a little farther from the first dead point (D1), sometimes it may be a little closer, and may even be on the first dead point (D1), but in any case, because in the preferred embodiment, reciprocating The position of the first end point (E1) of the trajectory (RP1) in the front and rear axial directions is rearward than the center of the circular trajectory (CP), so the aforementioned first dead point (D1) corresponds to the position before the circular trajectory (CP). The preset position on the upper quarter arc, so that even if the top end of the linkage (560) is at the first dead point (D1), because it is in the front upper quarter circle of the circular path (CP) On the arc, so the aforementioned torque can still be relatively easy The ground is moved from the position to the front and the bottom, that is, it starts to rotate in a predetermined counterclockwise direction.

Further, the third portion (566) of the interlocking member (560) is set to the front side of the connecting line between the first portion (top end) and the second portion (bottom end) in order to secure the stepping force of the first step described above. The linkage (560) can be formed to have a torsion force for moving the tip forward and downward, or can be said to enhance the torque, but in theory, even if the third portion is not located on the front side of the connecting line (for example, in the link) On the line even to the rear side), as long as the position of the third portion in the front-rear axis is more forward than the second portion (bottom end), the stepping force of the first step should also make the tip of the linking member (560) forward. Exercise below.

11 is a left side view of a sports equipment (600) according to a second preferred embodiment of the present invention, the basic structure of which is similar to that of the sports equipment (500) of the previous embodiment, and mainly includes a frame body (610) and a crank mechanism ( 620), two swing arms (650), two linkages (660), two rocking members (670), two driving members (680) and two pedals (690); the frame body (610) has a base (612) and a skeleton (614) disposed above the base (612), the skeleton (614) having a first rod (6141), a second rod (6142), a third rod (6143), and a fourth a rod member (6144) and a fifth rod member (6145), wherein the first rod member (6141) extends rearward and upward from a front end of the base (612), and the second rod member (6142) is formed by the first rod member The top end of (6141) extends horizontally forward, and the third rod member (6143) extends rearward and upward from the front end of the second rod member (6142), and the fourth rod member (6144) is intermediate from the base portion (612). The portion extends forwardly and upwardly to an intermediate portion of the first rod member (6141), and the fifth rod member (6145) extends forwardly from the intermediate portion of the first rod member (6141) to the third rod member (6143). Front end; this implementation The main difference between the example and the previous embodiment is that each rocking member (670) has a shaft center portion (672), a connecting portion (674) and a catching portion (676), wherein the axial center portion (672) The intermediate portion of the third rod (6143) of the skeleton (614) of the frame body (610) is pivotally connected, and the connecting portion (674) is opposite to the front side of the shaft portion (672), and can be axially centered (672). The swinging portion (674) is substantially in the shape of a rod or other suitable gripping shape, and is positioned above the axial center portion (672) so as to be axially and axially (672). swing.

In terms of the linkage of the hands and feet, for example, when the pedal (690) of the left foot moves downward and the pedal (690) of the right foot moves upward, the restriction portion (684) at the top end of the left driver (680) drives the left swing member (670). The connecting portion (674) of the front end swings downward, so the grip portion (676) of the left hand corresponds to The front swing, that is, is relatively far from the left pedal (690), and at the same time, because the restricting portion (684) of the top end of the right driving member (680) drives the connecting portion (674) of the front end of the right swing member (670) to swing upward, the right hand The catch portion (676) will swing back, that is, relatively close to the right pedal (690). In general, the left and right pedals (690) are raised or lowered in opposite directions to each other, and the left and right grip portions (676) are swung forward or backward in opposite directions to each other, and when one of the pedals is on one side When the (690) and the catching portion (676) are relatively close, the pedal (690) and the catching portion (676) on the other side are relatively far apart.

When the aforementioned exercise equipment (600) is used, the user steps on the left and right pedals (690), and can hold their hands on the left and right grips (676), respectively. The left and right two pedals (690) and the left and right two catching portions (676) are alternately stepped on and alternately pushed and pulled by the two feet and the two hands, so that the left and right two pedals (690) remain relatively along the first The two closed trajectories (CP2) circulate and move the left and right gripping portions (676) back and forth in opposite directions to each other, thereby alternately raising the legs and lowering the leg movements, and cooperating The hand movement of the aforementioned leg movement alternately pushes and pulls. The linkage mechanism between the aforementioned hand movement and the leg movement is relatively simple and low in cost. In the preferred embodiment, a fixed grip (616) can also be additionally provided at the top end of the third rod (6143) of the skeleton (614) of the frame body (610), so that the user can also move while exercising. The grip (616) is selected to be grasped, that is, the aforementioned hand movement is not performed.

12 to FIG. 15 are schematic structural diagrams of a single side of a sports equipment (700) according to a third preferred embodiment of the present invention. (Note: for example, only the left side of the sports equipment is schematically illustrated in the figure.
