Description

   Sports Equipment   

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

FIG. 1 shows a sports equipment (90) disclosed in U.S. Patent No. 9,199,115, which can be used by a user to perform leg movements of alternately raising and lowering feet with both feet, as well as hands that cooperate with the aforementioned leg movements. Alternate push-pull hand movements. In order to provide the aforementioned leg movements, the aforementioned sports equipment (90) mainly includes a crank mechanism (91), two left and right guide rails (92) (Note: the two are parallel and side by side, only the left guide rail is shown in the figure), and the left and right two Reciprocating member (93), left and right two wheels (94) and left and right two pedals (95), wherein each guide rail (92) is an inclined straight rod with an elevation angle of about 60 degrees in front, and a crank mechanism (91) is provided 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 to extend, and The aforementioned roller (94) is provided in front of the folding part and can be rotated and displaced on the corresponding guide rail (92), so that when the top of the reciprocating member (93) follows a circular track (CP) guided by the crank arm (911) During the cyclic movement, the part where the roller (94) is installed at the bottom end of the reciprocating member (93) will follow a reciprocating track (RP) guided by the guide rail (92) at the first end (E1) above the front and the bottom below The second end point (E2) is reciprocated; the pedal (95) for supporting the user's foot is fixed behind the bending part of each reciprocating member (93). 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 aforementioned sports equipment (90), it can be known that during the movement, the displacement range of the pedal (95) (especially closer to the tip of the roller (94)) is substantially equal to the first endpoint of the reciprocating trajectory (RP). The distance between (E1) and the second end point (E2) is approximately equal to the diameter of the aforementioned circular trajectory (CP). On the other hand, because the pedal (95) is fixed on the reciprocating member (93), during the movement, as the relative angles of the top and bottom ends of the reciprocating member (93) change periodically, the front, The relative angle of the rear two ends will also show corresponding periodic changes. For example, during the overall rise of the pedal (95), the heel end will deflect to a maximum height relative to the tip of the foot. During the overall decline of the pedal (95), The heel end is deflected to a minimum height relative to the tip of the foot, and the angular difference between them is equal to the change of the angle of the top of the reciprocating member (93) relative to the bottom, and the aforementioned change of the angle is also in accordance with the circular trajectory (CP). In other words, the larger the circular trajectory (CP), the higher the aforementioned maximum height, the lower the aforementioned minimum height, and the larger the angular difference.

Based on the aforementioned characteristics of the aforementioned sports equipment (90), if it is desired to provide the aforementioned leg movements with longer foot strokes and higher leg lifting heights, the diameter of the aforementioned circular trajectory (CP) must be basically lengthened, that is, a longer The crank arm (911), so that the displacement of the pedal (95) is correspondingly increased. However, enlarging the circular trajectory (CP) will increase the angle of the pedal (95), which may cause the user's ankle motion to be too large, and the angle between the calf and the footplate may exceed the appropriate ergonomic angle. Causes foot discomfort and even sports injuries such as tendon and ligament pain. Conversely, if a shorter crank arm (911) is used to restrain the angular change of the pedal (95) within an appropriate range, the leg travel and leg lift height of the aforementioned leg movements are relatively short and low, making it difficult to exercise And exercise effects are limited. Theoretically, increasing the distance from the top end of the reciprocating member (93) to the aforementioned 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 increased. A significant increase in the setting height of the crank mechanism (91) can narrow the aforementioned angle gap specifically, so it is not practical in practice. In a word, the structure of the aforementioned sports equipment (90) is difficult to take into account a longer pedal motion stroke and a smaller (or within a proper range) pedal angle variation range.

Based on the above structure of the aforementioned sports equipment (90), in the process of the pedal (95) rising from the lowest position to the highest position, the tip of the foot will follow an oblique trajectory substantially parallel to the aforementioned reciprocating trajectory (RP) (not shown in the figure). (Shown) shifted forward and upward, and in the first half of the ascent stroke, the heel end is significantly raised relative to the tip of the foot; when the pedal (95) is lowered from the highest position to the lowest position, the tip of the foot will roughly follow the aforementioned oblique Displace 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 as far as one foot is concerned, the above-mentioned leg movement is similar to the step in place, that is, using the power of the thigh to raise the knee to naturally raise the calf and feet (Note: When stepping in place, the raised foot will (Slightly ahead of the feet on the ground, not vertical rise), and then directly lower the thighs to bring the feet back to their original position. This kind of leg movement is slightly monotonous, the feet are raised and stepped down along the same route, and there is no movement of the calf to step forward and retract backward, the leg movement is less comprehensive, and the amount of exercise is insufficient.

In addition, we ideally hope that when performing this type of leg exercise, each position of the pedal on its movement track will present the most ergonomic angle of the position, so that the foot will be most natural and comfortable during exercise. However, based on the above structure of the aforementioned sports equipment (90), when the pedal (95) is reciprocated, when the heel end is raised and lowered relative to the tip of the foot, it completely follows the movement of the reciprocating member (93) in the exercise cycle. The angle change behavior is basically determined by the relative relationship between the circular trajectory (CP) and the reciprocating trajectory (RP). Although the design can be adjusted by related parameters (such as the crank arm (911) and The length ratio of the reciprocating piece (93), the inclination and position of the guide rail (92), etc.) to change the aforementioned angle change behavior, but these parameters are limited by the basic structure and space configuration of the aforementioned sports equipment (90) and cannot be greatly changed. Moreover, the results obtained are usually mixed, 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 sports equipment (90) after the exercise, normally one of the pedals (95) must be at the lowest position, and the other pedal (95) 95) is roughly in the highest position, so the next time the next user wants to use it, it is natural to first step the corresponding foot on the lower pedal (95), and then raise the other foot to the knee Step on the pedal (95) located at a high place, and then press down with a higher foot to lower the pedal (95) on one side, and raise the pedal (95) on the other side. Left and right two pedals (95) move up and down alternately; before starting the exercise, the left and right two pedals (95) are located near the highest position and the lowest position, respectively. Near the first end point (E1) and the second end point (E2) of the track (RP), at the same time, the top ends of the two left and right reciprocating members (93) are respectively located on the first dead end of the aforementioned circular track (CP) Near point (D1) and second dead point (D2) (Note: In the side view, the three points of the first dead point (D1), the circle center (O) of the circular trajectory (CP), and the first end point (E1) even In line, in addition, the circle center (O), the second dead point (D2), and the second end point (E2) of the circular trajectory (CP) are connected in a straight line). The starting position; moreover, when one of the users steps on the pedal (95) located at a low place first, a torsion with the roller (94) as a fulcrum will be formed on the reciprocating member (93) on the side. The aforementioned torque is usually The top of the reciprocating member (93) will be shifted along the circular trajectory (CP) from the vicinity of the second dead point (D2) in a counterclockwise direction (according to the perspective of Figure 1, the same below), so that the left and right two The tops of the reciprocating member (93) are respectively located on the sides of the counterclockwise direction of the first dead point (D1) and the second dead point (D2). 95), the direction of the force will cause the top of the reciprocating member (93) to rotate in a clockwise direction along the circular trajectory (CP), that is, when the user first presses the pedal (95), The top of the reciprocating member (93) must first approach and pass the dead point (D1) (D2) along the circular trajectory (CP) before continuing to revolve. At the same time, the roller (94) located at a high position must be slightly moved first. on Only after the first end point (E1) of the reciprocating trajectory (RP) does it begin to descend, and the roller (94) at the lower position first moves down slightly to the second end point (E2) of the reciprocating trajectory (RP). Rise, so the graphics card will be slightly lagging and laborious at startup.

As shown in FIG. 1, the upper half of the aforementioned sports equipment (90) also has left and right two handles (96) that can swing back and forth. The two handles (96) pass through a linkage mechanism (97) and a crank mechanism (91). Transmission connection (Note: only part is shown in the figure, the detailed structure and operation principle can refer to the previously disclosed US Patent No. 9,199,115), so that the swing of the left and right two handles (96) and the lift of the left and right two pedals (95) The predetermined modes are interconnected, so that the user can perform hand movements of alternately pushing and pulling hands with the aforementioned leg movements. The aforementioned interlocking mechanism (97) has a complicated structure and high cost.

The main object of the present invention is to provide a sports equipment, which can be used by a user to perform leg movements in which the feet are alternately raised up and down, and the length of the foot movement stroke and the angle of the foot in the aforementioned leg movement The magnitude of the change is not necessarily related. In other words, the aforementioned sports equipment can be designed to provide a long leg stroke and a high leg lift height, and at the same time, the angle of the foot can be controlled within a proper range.

Another object of the present invention is to provide a sports equipment that allows a user to perform leg movements in which both feet are alternately raised up and stepped down, and the aforementioned sports equipment is easier to design for the angle of the foot during exercise. Optimize changes in behavior.

Yet another object of the present invention is to provide a sports equipment that allows a user to perform leg movements in which both feet are alternately raised up and stepped down, and the aforementioned leg movements include a forward movement of the lower leg and a backward movement of the lower leg. Action, exercise is more comprehensive, more exercise.

Another object of the present invention is to provide a sports equipment that allows a user to perform leg movements in which both feet are alternately raised up and stepped down, and the sports equipment can be designed to make the leg movement better according to requirements. The ground simulates the movement of the foot and the angle of the foot when the human body steps on the ladder and moves upward.

Another object of the present invention is to provide a sports equipment that allows a user to perform leg movements in which both feet are alternately raised up and down, and each time the user wants to start the aforementioned leg exercise, Naturally and effortlessly move each component from the initial position to a predetermined direction.

Another object of the present invention is to provide a sports equipment, which can be used by a user to perform leg movements in which the feet are alternately raised up and stepped down, and can also be used by the user to selectively perform the double movements that match the aforementioned leg movements. The hand movements in which hands are alternately pushed and pulled. Among them, the linkage mechanism between hand movements and leg movements is relatively simple and low in cost.

In order to achieve at least one of the previous disclosure purposes, the sports equipment provided by the present invention includes a frame, two linkages, and two belts, and a first portion and a second portion of each of the linkages are respectively separated by a first portion on the frame. A guiding mechanism and a second guiding mechanism guide the movement on a circular trajectory and a reciprocating trajectory, and the first parts of the two linkage members remain opposite on the circular trajectory. When the part moves cyclically along the circular trajectory, the second part of the linking member will reciprocate between the first end point and the second end point of the reciprocating trajectory, and a third part of the linking member will follow a first A closed trajectory is cyclically moved, in which the first part of each of the linkage members remains higher than the second part and the third part, the entire reciprocating trajectory is positioned below the lowest point of the circular trajectory, and the first end point and The sharp angle between the connecting line of the second endpoint and the horizontal plane is greater than 45 degrees; a pivotal connection portion of each of the aforementioned driving members is pivotally connected to a third portion of the corresponding aforementioned connecting member, and will along the first closed rail together. During movement, a restricting portion of each of the driving members is guided by a third guiding mechanism on the frame to move on a restricting trajectory, so that the position of the pivoting portion on the first closed trajectory determines the restricting portion. The position on the restricted trajectory determines the angle and position of a support portion on the linkage with respect to the frame body. Moreover, when the pivotal portion moves cyclically along the first closed trajectory, the support portion will follow A second closed trajectory moves cyclically; the second closed trajectory is positioned below the lowest point of the circular trajectory as a whole, and the height difference between the highest position on the second closed trajectory and the lowest position in the vertical axis is greater than the foregoing The front-to-back gap between the frontmost position and the last position on the second closed trajectory projected in the front-rear axis.

Thereby, the user can step on the supporting portions of the two driving members respectively with appropriate feet, and appropriately apply force to cause each supporting portion to cyclically move along the aforementioned second closed trajectory (that is, to rise along the half-side trajectory, along with The other half of the trajectory is lowered), so that the legs are moved up and down alternately. Among them, the upward movement of the foot and the downward movement of the foot are moved along different routes with a back-and-forth gap. With the proper shape of the second closed trajectory, the leg movement can include the calf stepping forward and retracting backward. action.

Moreover, because the relative change of the limiting trajectory and the first closed trajectory can be designed to determine the angle change behavior and the angle change range of the driving element in the motion cycle, this is related to the angle change behavior of the linking element in the motion cycle. It is not necessarily related to the lifting displacement range, so the present invention can take into account a longer foot motion stroke and a smaller (or within a proper range) foot angle change amplitude, and it is easier to optimize the behavior of the foot angle change Adjustment. For example, by appropriately setting the restriction trajectory, the change angle of the relative angle between the tip of the foot and the heel end of the support portion may be smaller than the change angle of the relative angle between the first portion and the second portion of the link.

According to a preferred embodiment of the present invention, the second closed trajectory is divided into a first half that is relatively closer to the upper back and a second half that is relatively closer to the lower front; when the support part is in the first half of the second closed trajectory, When distinguishing points at the top of the first and second halves, the heel end of the support portion is located at a first height relative to the tip of the toe; when the supporting portion is at the distinguishing points at the bottom of the first and second halves of the second closed track, The heel end of the support portion is at a second height relative to the tip of the foot; when the support portion is at the middle point of the first half, the heel end of the support portion is at a third height relative to the toe; when the support When the part is at the middle point of the second half, the heel end of the support portion is at a fourth height relative to the tip of the toe; 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 with the support portion, and descends along the trajectory of the second half, the heel is raised relative to the toes in the first half of the ascent stroke, and In the first half of the descending stroke, the heel is lowered relative to the toe, so 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 that is relatively closer to the upper back and a second half that is relatively closer to the lower front. The trajectory length of the second half is shorter than the trajectory length of the first half; during the ascent of the support portion along the trajectory of the first half, the heel end of the support portion is raised to a relative to the tip of the foot first. After the maximum height is lowered, the supporting portion is kept substantially horizontal during the descending of the supporting portion along the trajectory of the second half. Accordingly, the aforementioned leg movements better simulate the foot movement trajectory and the foot angle change when the human body steps on the ladder and moves upward.

According to a preferred embodiment of the present invention, when the two links and the two drives are stationary, and the second part of the link is located at the higher end of the reciprocating trajectory, the user's feet are aligned. When the corresponding supporting part of the driving part applies a downward force, the force acts on the linking part through the pivoting part of the driving part, which will cause the second part of the linking part to move downward from the higher end of the reciprocating trajectory, At the same time, the first part of the linking member is displaced in a predetermined rotation direction from a first dead point of the circular trajectory. Correspondingly, the supporting part of the driving member will follow the first specific point of the second closed trajectory along the first The two halves are shifted to a specific point at the bottom. For example, the first dead point is located on a quarter arc above and above the circular trajectory, and the predetermined rotation direction corresponds to an initial downward displacement from the first dead point along the circular trajectory; each of the foregoing The third portion of the linking member is higher than the second portion, and the third portion is located on a front side of a straight line that passes through the first portion and the second portion simultaneously in a side view. For another example, the first dead point is located on a quarter arc above and behind the circular trajectory, and the predetermined rotation direction corresponds to displacement from the first dead point along the circular trajectory initially downward and backward; each The third portion of the link is lower than the second portion, and the third portion is located on a rear side of a straight line that passes through the first portion and the second portion simultaneously in a side view. With this, when the user wants to start the aforementioned leg exercise, naturally one of the feet is stepped on the pedal located at a low position, and then the other foot is stepped on the pedal located at a high position and a downward force is exerted, that is, It is possible to easily move components such as a pedal in a predetermined direction.

According to a preferred embodiment of the present invention, the third guiding mechanism includes two swinging members, each of the swinging members has an axis portion and a connecting portion, the axis portion is pivotally connected to the frame body, and the connecting portion It is pivotally connected with the corresponding restricting part of the driving member, so as to guide the restricting part to reciprocate along the arc-shaped restricting trajectory; further, each of the swinging members has at least one gripping part for the user to grasp, thereby The aforementioned sports equipment can be used by a user to selectively perform hand movements in which both hands alternately push and pull in cooperation with the aforementioned leg movements, and its structure is relatively simple and the cost is low.

16 is a schematic structural diagram of a single side of a sports equipment according to a fourth preferred embodiment of the present invention.

First, please refer to FIG. 2 to FIG. 5. The first preferred embodiment of the sports equipment (500) of the present invention has a frame (510). The frame (510) is mainly supported by a ground (G). The base (512) and a stand (514) fixed above the front end of the base (512). The aforementioned stand (514) is provided with a crank mechanism (520). The aforementioned crank mechanism (520) mainly includes a crank shaft (522) and two crank arms (524) (Note: only one of them is shown in the figure, and the other (The person is covered by other members), the aforementioned crank shaft (522) is pivoted laterally at a predetermined height position on the stand (514), and can rotate in both directions according to its own axis at this position. The axis of the crankshaft (522) (hereinafter referred to as the first axis, not labeled) defines the left and right axial directions of the sports equipment (500), that is, its opposite ends correspond to when the user uses the sports equipment (500) The left and right hand directions. The two crank arms (524) are respectively fixed to the left and right ends of the crank shaft (522) in an orthogonal manner, respectively, and extend in the radial direction outward from the ends of the crank shaft (522). The two crank arms (524) extend opposite to each other. In other words, in a side view, the outer ends of the two crank arms (524) will be held 180 degrees relative to each other with the first axis as the center.

There is a flywheel (530) below the crank mechanism (520). The flywheel (530) is also pivoted on the stand (514) according to the left and right axial directions, and the flywheel (530) and the crank shaft (522) ) Are connected through a belt transmission mechanism (540). When the crank mechanism (520) is driven by external force and rotates, the flywheel (530) will rotate in situ at a faster speed, so as to provide an appropriate rotational load and rotational inertia. Make the rotation of the crank mechanism (520) more stable and smooth. Preferably, the aforementioned sports equipment (500) may further be provided with a resistance device (not shown) that is matched with the flywheel (530) or connected to the crank mechanism (520), such as an eddy current brake, a generator brake, and a friction brake. , Water resistance device, wind resistance device, etc., are used to generate a resistance that can be adjusted by the user, so as to set the force required to drive the crank mechanism (520) to rotate, that is, set the difficulty of movement. The structure and application of the aforementioned resistance device belong to the common knowledge in the field of sports equipment (for example, wind resistance and magnetoresistive resistance devices are disclosed in the previously disclosed US Patent No. 9,199,115), and because the resistance device is not directly related to the creative content of the present invention The correlation is not necessarily included in the sports equipment of the present invention, so the description is omitted here.

The aforementioned sports equipment (500) has left and right swing arms (550) and left and right linkages (560) arranged symmetrically. Each swing arm (550) has a first end opposite to the front and a second end opposite to the rear. The aforementioned first end is pivotally connected to the frame body according to a second axis (not labeled) corresponding to the left and right axial directions. 510) The front end of the base (512) enables the aforementioned second end to swing up and down with the first end as an axis. Each linking member (560) is basically a long rod body with a top end and a bottom end. The top end is pivotally connected to the outer end of the crank arm (524) on the corresponding side, and the bottom end is pivotally connected to the pendulum on the corresponding side. Arm (550) second end. Based on the appropriately preset component size and positional relationship, the top of the link (560) can completely surround 360 degrees with the outer end of the crank arm (524), and when the top of the link (560) is along the crank arm (524) When the guided circular trajectory (CP) is cyclically moved, the bottom end of the linkage (560) will follow an arc-shaped reciprocating trajectory (RP1) guided by the swing arm (550) at a first end point (E1 ) And a second end point (E2). The first end point (E1) of the reciprocating trajectory (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) ( (See FIG. 7) The sharp angle between the horizontal plane (for example, the ground (G)) is greater than 45 degrees. In the preferred embodiment, the first endpoint (E1) is positioned in the front-rear axis than the second endpoint (E2). ) Is closer to the front, specifically, the front end 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 generally located below the lowest point of the circular trajectory (CP), and is further behind than the center of the circular trajectory (CP) (ie, the axis of the crank shaft (522)); As shown in FIG. 4 and FIG. 8, when the bottom end of the link member (560) is at the first end point (E1) of the reciprocating track (RP1) closest to the circular track (CP), the top of the link member (560) Corresponds to a first dead point (D1) on a quarter arc above and above the circular trajectory (CP) (Note: In a side view, the aforementioned first dead point (D1), circular trajectory (CP) The center of the circle and the first end point (E1) at three points are connected in a straight line); conversely, as shown in Figure 2 and Figure 6, when the bottom end of the link (560) is located on the reciprocating trajectory (RP1) farthest from the circular trajectory When the aforementioned second end point (E2) of (CP), the top of the link (560) will correspond to a second dead point (D2) on a quarter arc below the circular track (CP) ( Note: In the side view, the center point of the circular trajectory (CP), the aforementioned second dead point (D2) and the aforementioned second end point (E2) are connected in a straight line). Among them, since the center point of the circular trajectory (CP) and the first end point (E1) and the second end point (E2) of the reciprocating trajectory (RP1) in side view are not collinear, the circular trajectory (CP) The first dead point (D1) and the second dead point (D2) are not exactly 180 degrees opposite. Specifically, the connection line (L1) between the first end point (E1) and the second end point (E2) is The upward extension line passes directly below the circle center of the circular trajectory (CP), the first dead point (D1) is relatively positioned at an angle of about 70 degrees in front of the circle center, and the second dead point (D2) is relatively positioned The rear depression angle of the center of the circle is about 68 degrees. When the top and bottom ends of the linkage member (560) on one side are located at the aforementioned second dead point (D2) and the aforementioned second end point (E2), respectively, because the outer sides of the left and right crank arms (524) are The end stays 180 degrees opposite on the circular track (CP), so the top of the link (560) on the other side will correspond to the first dead point (D1) on the circular track (CP), below and adjacent to it. The position of the first dead point (D1), and the bottom end thereof corresponds to a position on the reciprocating trajectory (RP1) that is lower than the first end point (E1) and is adjacent to the first end point (E2).

Based on the top (first part) and bottom end (second part) of the linkage (560) being guided to the circular track (CP) and the reciprocating track (RP1) respectively relative to the frame body (510), The other predetermined part (third part) (566) of the link (560) is regulated to move on a first closed track (CP1) relative to the frame (510). In other words, the aforementioned part of the link (560) While the third part (566) orbits along the first closed trajectory (CP1), the top of the link (560) will make a round along the circular trajectory (CP), and the bottom end will follow The reciprocating track (RP1) reciprocates. In the preferred embodiment, the third portion (566) is set between the top and bottom ends of the linking member (560), and the third portion (566) is relatively positioned at the top and bottom ends in a side view. The front side of the connection line. Based on the preset spatial relationship of each component, the rotation direction of the top of the linking member (560) along the circular trajectory (CP) will be along the first closed trajectory (CP1) of the third part (566) in progress at the same time. ) The movement directions of the detours correspond to each other. For example, when the top of the link (560) moves in a counterclockwise direction along the circular trajectory (CP) (that is, downwards on the semicircle on the front side) Movement, upward movement on the semicircular arc on the rear side), the third part (566) will also move downward in the front half of the first closed trajectory (CP1), and move upward in the rear half. During the motion cycle where the top of the linking member (560) makes a circle along the circular trajectory (CP), the first part (ie, the top end) of the linking member (560) always remains higher than the aforementioned third part (566), Of course, it remains higher than the aforementioned second portion (ie, the bottom end). The first closed trajectory (CP1) is approximately a narrow ellipse or fusiform, and the acute angle between the long axis direction and the horizontal plane is greater than 45 degrees. In the preferred embodiment, the top of the first closed trajectory (CP1) is at The position in the front-rear axis is more forward than the bottom end. Specifically, the forward elevation angle of the top end of the first closed track (CP1) relative to the bottom end is about 65 degrees.

The aforementioned sports equipment (500) further includes left and right two swinging members (570) and left and right two driving members (580) arranged symmetrically. The two rocking members (570) are located in front of and above the crank mechanism (520), each having a shaft center portion (572) and a connecting portion (574), wherein the shaft center portion (572) corresponds to the left and right shafts according to a The third third axis (not shown) is pivotally connected to the top of the stand (514), and the aforementioned connection portion (574) is relatively rearward and upward of the shaft center portion (572), and can be moved up and down with the shaft center portion (572) as an axis. swing. Each of the driving members (580) is basically an L-shaped bent rod body, and a predetermined portion (hereinafter referred to as a pivot portion) (582) above the bent portion on the bottom side is pivotally connected to the corresponding side edge. The third part (566) of (560), so that the driving member (580) and the linking member (560) on the same side can be relatively deflected with the pivot joint (582) / third part (566) as the axis, and The pivoting portion (582) of the member (580) and the third portion (566) of the linking member (560) move together along the first closed track (CP1). In addition, a top end (hereinafter referred to as a restricting portion) (584) of each driving member (580) is pivotally connected to a connecting portion (574) of a swinging member (570) on a corresponding side, so that the aforementioned restricting portion (584) is relative to the frame ( 510) is restricted to move on an arc-shaped restriction trajectory (RP2) guided by the rocker (570). On the other hand, the bottom side of each driving member (580) is bent and extended backward to form a support portion for supporting the user's foot and bearing the user's force. In this preferred embodiment, a place is provided for the user. The pedal (590), which is stepped on with one foot, is regarded as a part of the aforementioned support portion, and has a tip of the foot opposite to the front and a heel of the foot opposite. The supporting part (including the pedal (590)) of each driving element (580) is relatively located at the rear and lower part of the pivoting part (582), and the height thereof is substantially the same as the bottom end of the corresponding linking element (560).

Because the distance and relative relationship between the pivoting part (582), the restricting part (584), and the supporting part (hereinafter referred to as the pedal (590)) on the driving member (580) are unchanged, based on the appropriate preset Component size and positional relationship. When the pivot joint (582) of the driving member (580) moves along the first closed track (CP1), the position of the pivot joint (582) on the first closed track (CP1) will be determined. The position of the restricting portion (584) on the restricting trajectory (RP2) determines the position and angle of the pedal (590) relative to the frame (510). When the pivoting portion (582) of the driving member (580) moves cyclically along the first closed trajectory (CP1), the restricting portion (584) of the driving member (580) will follow the aforementioned arc-shaped restricting trajectory (RP2) at its position. The top and bottom are reciprocated. At the same time, a predetermined part of the pedal (590 in the figure, the pedal center is taken as an example) will cyclically move relative to the frame (510) along a second closed trajectory (CP2) (Note: In the following, for example, "the predetermined part of the pedal moves along the second closed trajectory" may be simply expressed as "the pedal moves along the second closed trajectory"), and the angle of the heel end relative to the tip of the foot will be periodic Variety. The movement direction of the pedal (590) orbiting along the second closed track (CP2) and the movement direction of the pivoting portion (582) of the driving member (580) along the first closed track (CP1) correspond to each other. That is, corresponding to the rotation direction of the top end of the linkage member (560) along the circular trajectory (CP). The sharp angle between the top and bottom connecting lines (L2) (see Figure 7) of the aforementioned restricted trajectory (RP2) and the horizontal plane is greater than 45 degrees. In this embodiment, the forward elevation angle of the aforementioned top to the bottom is about 49 degrees .

Further, the aforementioned second closed trajectory (CP2) is located below the lowest point of the circular trajectory () as a whole, and has an elongated oval or shuttle shape. As shown in Figures 4 and 8, when the top and bottom ends of a linkage (560) are respectively located on the first dead point (D1) on the circular trajectory (CP) and the first endpoint of the reciprocating trajectory (RP1) When (E1), the third portion (566) of the aforementioned linking member (560) and the pivoting portion (582) of the corresponding driving member (580) will be located approximately at the top of the first closed track (CP1), so that the aforementioned driving The restriction part (584) of the piece (580) is also located approximately at the top of the restriction track (RP2), while the pedal (590) corresponds to a top specific point (P1) on the second closed track (CP2), and the pedal (590 ) The heel end is at a first height relative to the tip of the foot. In this example, the rear elevation angle is about 4 degrees. Conversely, as shown in Figures 2 and 6, when the top and bottom 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 part (566) of the aforementioned linkage (560) together with the corresponding The pivoting portion (582) of the driving member (580) will be located approximately at the bottom end of the first closed track (CP1), so that the restricting portion (584) of the driving member (580) is also located approximately at the limiting track (RP2). The bottom end, and the pedal (590) corresponds to the second closed track A bottom specific point (P2) on the track (CP2), the heel end of the pedal (590) is located at a second height relative to the tip of the foot, which is a substantially horizontal position in this example, lower than the aforementioned first height. The position of the top specific point (P1) in the front-rear axis is more forward than the bottom specific point (P2). The connection direction of the two points (P1) (P2) is defined as the long axis direction of the second closed trajectory (CP2). The acute angle between the foregoing long-axis direction and the horizontal plane is greater than 45 degrees, and about 68 degrees in the preferred embodiment. The second closed trajectory (CP2) has a short-axis direction perpendicular to the aforementioned long-axis direction, and the maximum width of the second closed trajectory (CP2) in the short-axis direction is smaller than that of the top specific point (P1) and the bottom specific point (P2). Half the straight distance. In addition, the height difference between the highest position and the lowest position on the second closed trajectory (CP2) projected in the up-down axis is greater than the front-to-back difference between the foremost position and the last position on the second closed trajectory () projected in the front-back axis, in other words In the course of the pedal (590) making a circle along the second closed trajectory (CP2), the vertical difference between the upward and downward movement of the pedal (590) will be greater than the horizontal difference between the forward and backward movement of the pedal ().

As shown in FIG. 10, the second closed trajectory (CP2) is divided into a first half (H1) that is relatively close to the upper back and a lower part that is relatively closer to the front and lower according to the aforementioned specific point (P1) and the aforementioned bottom specific point (P2). The second half edge (H2), the intermediate point (P3) of the first half edge (H1) in the front-back axial direction is located further rearward than the intermediate point (P4) of the second half edge (H2). As shown in FIG. 3 and FIG. 7, when the pedal (590) is positioned at the middle point (P3) of the first half (H1), the heel end of the pedal (590) is positioned at a third height relative to the tip of the foot. In this example, the rear elevation angle is about 3 degrees, which is higher than the aforementioned second height. As shown in FIG. 5 and FIG. 9, when the pedal (590) is positioned at the middle point (P4) of the aforementioned second half (H2), The heel end of the pedal (590) is located at a fourth height relative to the tip of the foot. In this example, the rear depression angle is about 1 degree, which is lower than the aforementioned first height. In this way, when the pedal (590) moves along the second closed trajectory (CP2) in a circling direction that rises along the trajectory of the first half (H1) and descends along the trajectory of the second half (H2) In the first half of the ascent stroke, for example, from the bottom specific point (P2) to the middle point (P3) of the first half (H1), the heel end of the pedal (590) rises relative to the tip of the foot; Ground, in the first half of the descending stroke, for example, from the top specific point (P1) to the middle point (P4) of the second half (H2), the heel end of the pedal (590) is lowered relative to the tip of the foot. In the present invention, the gap between the third height being higher than the second height and / or the gap between the fourth height being lower than the first height may be more apparent by appropriately presetting the spatial relationship of the components.

Because the top ends of the left and right linkages (560) remain 180 degrees on the circular track (CP) in a side view, the pivot joints (582) of the left and right linkages (580) are at the first position. The closed track (CP1) is also maintained at a relative position. Correspondingly, the left and right pedals (590) are also maintained at a relative position on the second closed track (CP2). For example, when one of the pedals (590) At the top / bottom of the second closed trajectory (CP2), the other pedal (590) will be located at the opposite bottom / top, and it is assumed that the top of the link (560) is a counterclockwise clock in FIG. 2 The direction revolves on a circular trajectory (CP), then, roughly speaking, when one of the pedals (590) moves forward and upward along the first half (H1) of the second closed trajectory (CP2), the other The pedal (590) moves backward and downward along the second half (H2) of the second closed track (CP2).

When using the aforementioned sports equipment (500), the user steps his feet on the left and right two pedals (590), and grabs his hands on the left and right two grips on the top of the stand (514), respectively. (516), stepping on the left and right two pedals (590) alternately with both feet in cooperation with each other, keeping the left and right two pedals (590) cyclically moving relatively along the second closed trajectory (CP2), thereby performing Legs with both legs raised up and stepped down alternately.

According to an aspect of the present invention, the crank mechanism (520) in the previously disclosed preferred embodiment forms a first guide mechanism for guiding the top ends (first portions) of the left and right linkage members (560) relative to The frame body (510) moves along a circular trajectory (CP) and keeps the top ends of the two linkage members (560) opposite to each other; the two swing arms (550) form a second guiding mechanism for guiding the left and right The bottom end (second portion) of the two right-hand linking members (560) moves relative to the frame body (510) along a reciprocating track (RP1); the aforementioned two swinging members (570) form a third guiding mechanism for guiding The top ends (restriction portions) of the left and right two driving members (580) move relative to the frame body (510) along a restriction track (RP2). In other embodiments of the present invention (there is no corresponding drawing), different types of mechanisms may be used to guide the same or similar movement trajectories. For example, a guide rail or a guide groove may be provided on the frame body (510) to replace the aforementioned pendulum. The arm (550) and / or the aforementioned swinging member (570) are installed at the second portion of each linking member (560) and / or the restricting portion of each of the driving members (580) and can slide along the aforementioned guide rail or guide groove Wheel. The reciprocating trajectory and the limiting trajectory in the present invention may show a straight line or a non-arc curve, and the foregoing limiting trajectory may also be closed.

Compared with the sports equipment capable of performing similar leg exercises in the prior art, the aforementioned sports equipment (500) provided by the present invention has several advantages, which will be explained one by one below. First, because the relative relationship between the aforementioned restricted trajectory (RP2) and the aforementioned first closed trajectory (CP1) can be used to determine the angular change behavior and angular change range of the driver (580) during the motion cycle, this is related to the linkage ( 560) There is no necessary relationship between the angle change behavior and the lifting displacement during the exercise cycle, so the aforementioned sports equipment (500) can take into account the longer pedal (590) movement stroke and the smaller (or within a proper range) pedal (590) The magnitude of the angle change, and it is relatively easy to optimize the angle change behavior of the pedal (590). In other words, the aforementioned sports equipment (500) can be designed to provide the aforementioned leg movement with a longer leg stroke and higher leg lifting height, and at the same time, the angle variation range of the foot is controlled within an appropriate range. In this preferred embodiment, during the period in which each part revolves along its trajectory or reciprocates, the change angle of the top end of the linking member (560) relative to the bottom end is about 19 degrees, and the pedal The angle of change of the heel end of the (590) relative to the tip of the foot is about 4 degrees, which is smaller than the angle of the link (560).

When using the aforementioned sports equipment (500) for leg exercises, the pedal (590) may rise along the first half (H1) of the second closed trajectory (CP2) and descend along the second half (H2) Method, or cyclic movement in the manner of rising along the second half (H2) and descending along the first half (H1). In short, the user's feet are lifted up and down when the foot is down. Different routes of motion, with the proper shape of the second closed trajectory (CP2), the aforementioned leg movements can include the movement of the calf stepping forward and retracting backward, the movement is more comprehensive, and the amount of exercise is more.

As mentioned earlier, when the pedal (590) cyclically moves along the second closed trajectory (CP2), if its detour direction is to rise along the trajectory of the first half (H1), along the second half ( H2), the heel end of the pedal (590) rises relative to the tip of the foot in the first half of the ascent stroke (for example, from the second height to the third height), and in the first half of the ascent stroke, Segment, the heel end of the pedal (590) is lowered relative to the tip of the foot (for example, from the aforementioned first height to the aforementioned fourth height), in other words, when the user's foot supported by the pedal (590) is at the lowest position of the motion track When starting to lift upwards, the heel will rise relative to the toes. When the user's foot starts to step down from the highest position, the heel will fall relative to the toes, so the movement is more natural and comfortable. However, because the aforementioned crank mechanism (520) can rotate freely in both directions, the user can still change the way in which he applies the left and right pedals (590) (e.g., the left and right pedals (590) When the height is approximately the same, it is controlled to lower the left foot and raise the right foot, or to control the right foot to descend and the left foot to rise), so that the pedal (590) follows the second closed trajectory (CP2) in the opposite winding direction. Cyclic motion, that is, rising along the trajectory of the second half (H2) and descending along the trajectory of the first half (H1).

However, the sports equipment (500) of the previously disclosed preferred embodiment is actually designed to allow the user to naturally drive the pedal (590) to cyclically move in a preset winding direction, that is, unless the user deliberately controls its application Force mode, otherwise the pedal (590) usually rises along the first half (H1) of the second closed trajectory (CP2), and descends along the second half (H2), so the direction of detour is more natural. The movement mode, and the preset angle and the angle change mode of the pedal (590) at various positions are also designed to match such a bypass direction. In detail, based on the structure of the aforementioned sports equipment (500), when the user leaves the sports equipment (500) after exercising, normally it must be one of the pedals (590) (here, the left pedal is used as Ex.) It is roughly at the lowest position of the second closed track (CP2), and the pedal (590) on the other side (here, the right pedal is taken as an example) is roughly at the highest position. Therefore, the next or next user To use it, naturally press the left foot on the left pedal (590) near the lowest position (Note: if the pedal (590) has not been in the lowest position before, this action usually lowers the pedal (590) further) , And then press the right knee with the right foot on the right pedal (590) near the highest position, and then press down with the right foot to lower the right pedal (590), while the left pedal (590) rises accordingly. In this way, the left and right pedals (590) are alternately raised and lowered. Among them, the left pedal (590) is located at the lowest position of the second closed trajectory (CP2) before starting the movement, which means that the left linkage (560) The top dead center is the second dead point (D2) on the lower quarter arc behind the circular track (CP). ), At the same time, the top of the right-hand link (560) will be located in a quarter arc above and above the circular track (CP), and relatively below the first dead point (D1); when higher When pressing the right pedal (590) down with his right foot, the force will act on the third part (566) of the right link (560) through the pivot joint (582) of the right drive (580), because the third The part (566) is relatively located on the front side of the connecting line between the top and the bottom of the link (560). Therefore, the downward force acting on the third part (566) will form the link (560) so that its top is opposite. The torque of counterclockwise deflection at the bottom makes the bottom end of the right-hand link (560) move along the reciprocating trajectory (RP1), and the top end moves forward and downward in a counterclockwise direction along the circular trajectory (CP). Corresponding to this, the right pedal (590) descends along the second half (H2) near the top specific point (P1) of the second closed trajectory (CP2), while the left pedal (590) moves from the second closed trajectory (H2) Near the specific point (P2) at the bottom of CP2), it rises along the first half (H1), and then, by the inertia of the flywheel (530) and the user ’s regular application In the force mode, the left and right pedals (590) will cyclically move along the second closed trajectory (CP2) in such a detour direction.

As mentioned above, when the motion is to be started from a static state, the top of the relatively high link (560) will directly circle downward on the circular trajectory (CP) and away from the first dead point (D1) next to it. (Rather than orbiting upwards and approaching and passing through the dead point (D1)), the bottom end also drops directly near the first end point (E1) of the reciprocating trajectory (RP1) (instead of rising slightly to the first end first) Point (E1) then turns down), so the user can step on the first step with ease and effort, and naturally move all the components in a predetermined direction.

It must be pointed out here that the starting position and starting action of the components described above are typical examples; in practice, due to mechanical factors (such as friction between components) and human factors (such as the user's influence on the component position), Each time the user wants to start exercising and is ready to step on the aforementioned first step, the top of the relatively high link (560) will not always be at a fixed position on the side of the counterclockwise direction of the first dead point (D1). , Sometimes it may be slightly far away from the first dead point (D1), sometimes it may be slightly closer, or it may even be located on the first dead point (D1), but in any case, because in the previously disclosed preferred embodiment, the back and forth The first end point (E1) of the trajectory (RP1) in the front-rear axis is further behind than the center of the circle of the circular trajectory (CP), so the first dead point (D1) corresponds to the front of the circular trajectory (CP). The preset position on the upper quarter arc, so even if the top of the link (560) is at the first dead point (D1), it is a quarter circle above the front of the circular track (CP) Arc, so the aforementioned torsion can still relatively easily move it from the beginning to the lower position, that is, Start to orbit in a predetermined counterclockwise direction.

In addition, the third part (566) of the link (560) is set on the front side of the connecting line between the first part (top end) and the second part (bottom end) so as to ensure the stepping force in the first step. It can form a torsional force on the linkage (560) to move its top forward and downward, or to increase the aforementioned torsion, but in theory, even if the third part is not located on the front side of the connection line (for example, on the connection Line or even the rear side), as long as the third part is positioned more forward in the front-rear axis than the second part (bottom end), the stepping force of the aforementioned first step should also make the top of the linkage (560) forward Downward movement.

FIG. 11 is a left side view of the sports equipment (600) according to the second preferred embodiment of the present invention. The basic structure is similar to the sports equipment (500) of the previous embodiment, and mainly includes a frame (610) and a crank mechanism ( 620), two swing arms (650), two linkage members (660), two swing members (670), two drive members (680), and two pedals (690); the main difference between this embodiment and the previous embodiment is that: Each swing member (670) has an axis portion (672), a connecting portion (674), and a gripping portion (676), wherein the aforementioned axis portion (672) is pivotally connected to the frame body (610), and the aforementioned connection The portion (674) is relatively located in front of the axis portion (672), and can swing up and down with the axis portion (672) as an axis. The grip portion (674) is practically bar-shaped or other suitable shape for gripping. It is relatively positioned above the shaft center portion (672), and can swing back and forth with the shaft center portion (672) as an axis.

In terms of hand-foot linkage, for example, when the pedal (690) of the left foot moves downward and the pedal (690) of the right foot moves upward, the restriction part (684) at the top of the left-side driving member (680) drives the left-side swinging member (670). The connecting part (674) at the front end swings downward, so the gripping part (676) of the left hand swings forward, that is, relatively far away from the left pedal (690), and because of the limitation of the top end of the right-hand drive (680) The part (684) drives the connecting part (674) at the front end of the right-hand swinging member (670) to swing upward, so the gripping part (676) of the right hand will swing backward, that is, relatively close to the right pedal (690). Generally speaking, the left and right two pedals (690) rise or fall in opposite directions to each other, and the left and right two gripping portions (676) swing forward or backward in opposite directions to each other, and when one of the pedals on one side (690) and the gripping portion (676) are relatively close, the pedal (690) and the gripping portion (676) on the other side are relatively far away.

When using the aforementioned sports equipment (600), the user depresses his feet on the left and right two pedals (690), and can hold his hands on the left and right two gripping portions (676), respectively. Use both feet and hands to step on the left and right two pedals (690) and the left and right two gripping portions (676) alternately and alternately push and pull, so that the left and right two pedals (690) remain relatively along the first The two closed trajectories (CP2) are cyclically moved, and the left and right two gripping portions (676) are swung back and forth in opposite directions to each other, thereby performing the leg movements of alternately raising and lowering the feet, and matching The hands with the aforementioned leg movements are alternately pushed and pulled. The aforementioned linkage mechanism between the hand movement and the leg movement is relatively simple and the cost is low. In this preferred embodiment, a fixed grip (616) can also be provided on the top of the frame (610), so that the user can choose to grip the grip (616) during exercise, that is, not Perform the aforementioned hand movements.

Please refer to FIG. 12 to FIG. 15, which are 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 shown in the figure. The linking member (760), the driving member (780), and the support / pedal (790), and the structure of the right side of the equipment is symmetrical and omitted (in the preferred embodiment), each linking member (760) is the same A first part (762) guided to move on a circular track (CP), a second part (764) guided to move on a reciprocating track (RP1), and a corresponding driving member (780) The third portion (766) of the pivotal portion (782) pivoted to each other and moving along a first closed track (CP1), the difference is that the third portion (766) of the aforementioned linkage (760) is lower than the second portion (764), and the third part (766) is relatively behind the connecting line between the first part (762) and the second part (764); based on the preset spatial relationship of each part, the linkage (760) The turning direction of the first part (762) along the circular track (CP) will be the same as the moving direction of the aforementioned third part (766) along the first closed track (CP1). On the contrary, it is equal to the movement direction of the support / pedal (790) that is going along the second closed trajectory (CP2) at the same time. For example, when the first part (762) of the linkage (760) is When moving in a clockwise direction along the circular trajectory (CP) in FIG. 12 (that is, as in the sequence of changes from FIG. 12 to FIG. 15), the pedal (790) will be on the second half of the second closed trajectory (CP2) (No. (Half of the sides) move up, and move down the front half (second half); In addition, as shown in Figure 14, when the second part (764) of the linkage (760) is located at the highest position of the reciprocating trajectory (RP1) When the first end point (unlabeled), the first part (762) of the linkage (760) will correspond to a first dead point (unlabeled) located on a quarter-arc above the circular track (CP). ) By this, similar to the principle described in the first preferred embodiment, when the user wants to start using the sports equipment (700), the user presses down the support / pedal (790) located at a high place. At that time, its force will cause the first part (762) of the linkage (760) to revolve in the aforementioned clockwise direction, so that the pedal (790) will naturally circulate in a preset winding direction.

FIG. 16 is a schematic structural diagram of a single side of a sports equipment (800) according to a fourth preferred embodiment of the present invention (Note: For example, the figure only schematically illustrates the crank arm (824) and the linkage on the left side of the sports equipment (860) and the driver (880), and the structure of the right side of the equipment is symmetrical with it and is not shown). In this embodiment, the second closed track (CP2) of the support / pedal (890) has the same definition The previous top specific point (P1) and the bottom specific point (P2), and the second closed trajectory (CP2) is divided into the first half (H1) and the second half (H2) according to the same definition as before.
