Description

1272955 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to sports equipment, and more particularly to a sports apparatus that allows a user to perform a reciprocating motion of a foot. [Prior Art] Commonly used leg (lower body) sports equipment, including treadmills, exercise bikes, elliptical machines, slide machines, steppers, space walkers, etc. In addition to the treadmill, the above various sports equipment utilizes a movable pedal to guide the user's feet to move on the predetermined obstruction, causing the leg (or lower body) to perform a predetermined predetermined action, for example, the pedal of the bicycle is The guiding feet circulate on a circular track. The elliptical machine, as the name suggests, guides the two feet to circulate on an elliptical or approximately elliptical trajectory. The so-called sliding stepper, stepper, and spacewalker are generally used. In general, the obstruction is a horizontal straight line, an arc with the center of the circle in front and an arc with the center of the circle at the top, and both guide the legs to reciprocate on the aforementioned track. Of course, there are many pedal trajectories and complicated leg sports equipment, which are not listed here. The invention belongs to a sports equipment for guiding a pair of feet to reciprocate on a predetermined track, and the motion form is substantially between the slide machine and the step machine, and the related prior art includes the US No. 3970302, No. 4496147, No. 5007631 , No. 5,180,351, No. 5,186,697, and No. 5,195,935. The sports equipment disclosed in each of the above patents has two left and right pedals that can slide back and forth along the inclined rail, and can be similarly climbed by the user.

1272955 Mountain, alternate stepping leg movement. Among them, the United States No. 3970302, No. 5007631, No. 5180351, and No. 5159 5 3 5 said that the patents are all connected by the length of the rope or the key bar to the left and right two pedals, so that the two pedals are equal The reverse movement of the ground (one of the pedals descends a predetermined distance backward, that is, forcing the other pedal to rise forward by the same distance), but the rope and the chain are prone to breakage. The US Patent No. 4496147 and many subsequent patents use the two hydraulic cylinders connected to reverse the left and right pedals. However, due to factors such as the compressibility of the oil, the synchronous action is not correct. U.S. Patent No. 5,186,697 discloses the use of a relatively two-cranked arm to maintain the reverse movement of the left and right pedals. Although the structure is relatively stable, the movement of the pedal is directly limited by the length of the crank arm, which makes the movement efficiency and equipment. The volume creates a dilemma; in addition, when the user uses the invention to perform an UpWard stepping motion, the two "dead-centre" in the stroke are easy because the crank arm completely depends on the pedal to rotate through the connecting rod. The blockage caused by the pedal slip, i: speed, makes the reciprocating motion of the foot unable to perform smoothly and smoothly. In terms of the resistance to motion, the above patent also discloses a variety of mechanical structures for providing additional, such as shock absorbers, tension springs, friction belts or friction hoops. The lack of the above various resistance devices is that the user cannot easily adjust the resistance during the movement. On the other hand, the sports equipment provided by each patent is focused on the movement of the user, the user's double The hand is not without any dependence, that is, Z is caught on the armrest of the arm and cannot move together. The US Patent No. 07631 has two movable grips, which can be synchronously lifted on the same way with the pedals on the same side of the 1272955 side. However, this type of exercise is not natural in terms of hand movements or the manner in which the hands and feet are coordinated. Another patent application of the US Patent Publication No. 2004/0224825 discloses a leg sports equipment, the movement thereof. The shape is similar to the space walker, but the center of the pedal swaying trajectory is relatively located at the upper rear of the circular trajectory, that is, the user's foot is roughly moved from a lowest point along the arc to the upper point to the highest point. Then, from the highest point, the original track is moved backwards to the lowest point, so that the same leg lifting motion can be performed. The patent application is also an embodiment. There are two grips that can be yawed forward and backward, and the left and right grips are coupled to the left and right pedals, thereby allowing the upper and lower body to move. However, the linkage mechanism makes the same side The grip and the pedal will move forward or backward at the same time, that is, the user must perform the whole body movement in the same way.

Further, another object of the present invention is to provide a sports equipment capable of performing a leg movement in which the feet are reciprocally reciprocated, wherein the step (four) for supporting the foot of the person (four) has a length _ length, ^ Use exercise to have higher exercise efficiency. a further object of the present invention is to provide a sports equipment that can provide

1272955 The user performs the leg movement of the two legs reciprocally and reciprocally, and allows the user to selectively perform the upper body reversal coordinated with the lower body during the movement of the leg. Still another object of the present invention is to provide a sports apparatus capable of allowing a player to perform leg movements in which the two legs reciprocate and reciprocate, and to easily adjust the movement resistance during the movement of the front block. In order to achieve the above object, the user equipment provided by the present invention mainly includes a body, and the frame body is provided with a winding mechanism, which has a loop that can be circulated on a circular or approximately circular closed track. Two rewinding joints of the movement, the two joints are kept on opposite sides and interlocked with each other; the rewinding mechanism is connected with a flywheel pivotally disposed on the frame body, so that the two joints and the flywheel can be interlocked with each other; There are guide rails for supporting and guiding (four) boards, the rails can be fixedly arranged on the frame body at a predetermined degree, and can also be arranged on the frame body in an angle adjustable manner; the left and right pedals can be slid back and forth along the guide rails, and Each of the left and right pedals is coupled to the two rewinding points in a reverse direction to each other through a link assembly and a corresponding rewinding contact. - Compared with the conventional rope and chain transmission method, 'the aforementioned sports equipment is stable in structure', it is not easy to loosen the parts, and the pedal slips; the inertia from the flywheel is obtained, so that the user can smoothly and smoothly perform the double The legs move back and forth reciprocally. In a preferred embodiment, each of the link assemblies has a swing arm, a jib, and a linkage rod, and each swing arm is pivotally coupled to the frame body, and each of the jib arms is coupled to the swinging end of the swing arm and the pedal Between each of the linkage rods is connected between the rewinding contact and the swing arm. Because the position of the pedal connected to the swing arm is better than the return = contact 8

The position of the I272955 connected to the swing arm is farther away from the swing center of the swing arm, so the travel of the pedal can be moderately larger than the diameter of the motion trace of the wraparound joint. Therefore, the aforementioned sports equipment can be provided under an appropriate volume. Sufficient pedal travel 0 In a comparative embodiment, the foregoing sports equipment further includes a _ hand movement mechanism having left and right grips movably disposed on the frame body, the two grips and the second The pedals are coupled to each other so as to be interlocked with each other. In a preferred manner, the left and right yaw rods extending longitudinally may be disposed, and a predetermined portion between the top and bottom ends of each yaw rod is pivotally connected to the frame body, and the top portion is disposed on the frame. For the user to grasp, the bottom end is connected to the pedal (or to the swing arm) through a reciprocating link, so that the grip of the same side and the pedal move in opposite directions to provide a better body motion type. In a preferred embodiment, the user can electronically control a resistance device through the console of the sports equipment to adjust the motion resistance of the two winding contacts. In one preferred form, the resistance device can be a conventional eddy current brake (ECB) having a magnetic force assembly that adjusts the relative position of the flywheel, thereby controlling the resistance to movement of the flywheel and the rewind contact. In addition, in a preferred embodiment, an angular adjustment insertion is provided between the guide rail and the frame body, and the user can also control the angle adjustment device in an electronically controlled manner, thereby changing the guiding angle to improve the difficulty of movement or reduce. [Embodiment] Hereinafter, the structure of a preferred embodiment of the technical features of the present invention will be described in detail with reference to the accompanying drawings, and the functions and features which can be obtained. 9 1272955 Referring first to fourth to fourth embodiments, there are sequentially a perspective view, a left side view, a top view and a front view of a preferred embodiment of the present invention. (Notes • Directions such as “Before”, “After”, “Left”, and “Right” in this manual correspond to the user’s perception of the direction of use, while the left side view, top view and front view The figure is a graphical indication, wherein the left side view corresponds to the left side of the user and the front view corresponds to the back side of the user.) As shown, the sports equipment of a preferred embodiment of the present invention mainly comprises There are: a frame body (10) placed on the ground, two left and right guide rails (20) disposed in the rear half of the frame body, and two left and right pedal groups (3 ()) disposed on the guide rail, and are disposed at a rewinding mechanism (4〇) at the end of the frame body, a flywheel (52) connected to the rewinding mechanism, a left and right two-link assembly (6〇) connecting the rewinding mechanism and the two pedals, and a hand movement mechanism (70) ). The frame body (10) is used as a mounting base for other components, and is generally composed of a base (11), a pole (12), a front bracket (13), and left and right side frames (14). Wherein, the base (1) is a water that can be stably placed on the ground: the frame, the upright (10) is erected and fixed to the base ((1) is located in front of the center, and the support (13) is fixed to the upright (12) and Between the bases (11), the left and right side frames (14) are respectively fixed on the left and right sides of the base (11), and are in the form of two frames. The rear of the frame body (10) forms an open entrance and exit. When the user wants to use or leave the sports equipment, it can enter and exit from here. In addition, the pole (I2) tops the financial control from (10), as the interface between the fairy and the sports equipment, that is, the user controls the sports equipment, and the sports equipment displays itself. The electronic device of the state will be described in the following. Each guide rail (20) is an elongated rail extending in a straight line, and the two rails (10)

1272955 is disposed in parallel with the left and right sides of the frame body (10), between the left and right side frames (14). Each of the guide rails (2 turns) has a rear end close to the ground and a front end at a predetermined height from the ground. In other words, the guide (2 〇) long axis presents a predetermined elevation angle with respect to the ground. In the present embodiment, the elevation angle of the guide rail (20) or the angular relationship of the guide (20) with respect to the frame (1) can be selectively adjusted, which will be further described later. The one pedal group (30) is respectively disposed on the two guides (2Q). Please refer to the fifth and sixth figures. Each pedal group (3〇) is roughly composed of a sliding seat (31) and two. The roller (32), the lower roller (33) and a pedal (34) are combined, and the sliding seat (31) is formed by bending a metal plate, and has a main board (35) and a parallel two by the main board. Two side plates (36) extending vertically on the side, the sliding seat (31) is sleeved on the guide rail (20), so that the main board (35) is located above the guide rail (20), and the two side plates (36) are respectively positioned Hold (2 〇) left and right sides; the rollers (32, 33) are pivoted between the two side plates (36) in the left and right directions, wherein the two upper rollers (32) are one The front and rear positions are above the guide rail (2〇), and the lower roller shaft (33) is located below the guide rail (20). Each of the left and right ends of each roller shaft (32, 33) has a large outer circular end. The rollers (37, 38) are respectively contacted at the corner portions of the shape of the guide rails (2〇), whereby the carriage (31) can be smoothly and smoothly slid along the long axis of the guide (20). Each pedal group (3〇) is used for the user to step on the pedal (34) is fixed above the sliding seat, so the top surface (support surface) maintains a fixed angle with the long axis of the guide rail (20), in other words, when When the guide rail (2〇) is fixed at a selected angle with respect to the ground, the pedal (34) is raised forward or backward along the guide (2〇) in such a manner that the angle of the support surface is constant. The returning and winding mechanism (40) is disposed on the front bracket (13) of the frame body (10), and includes a crankshaft (4D, two crank arms (42) and a large pulley (43), wherein the crankshaft The ui) is pivotally disposed on the front bracket (10) in the left and right directions, and the two crank arms 2 are vertically fixed to the opposite ends of the crank shaft (41) in a symmetrical manner, and the outer ends of the crank arms (42) are formed. A wrap point (44) is provided once, thereby providing a two-way wrap (44) that maintains 18 degrees of relative orientation on a circular path. The large pulley (43) is coaxially attached to the crankshaft (41) and is positioned between the left and right crank arms (42).

The flywheel (52) is also pivotally disposed on the front bracket (13) of the frame body (1〇) in the left and right directions, and is positioned below the rewinding mechanism (40). One side of the flywheel (52) is coaxially fixed to a small pulley (54), and the small pulley (54) is located directly below the large pulley (43), and a transmission belt (5β) is disposed between the two (54, 43). ), thereby causing the flywheel (52) and the crankshaft (41) to rotate together, and by the diameter difference between the large and small pulleys (43, 54), the crankshaft (41) to the flywheel (52) is formed. An accelerating transmission mechanism, that is, when interlocking with each other, the rotational speed of the flywheel (52) is tied to the crankshaft (41) such that the torque of the crankshaft (a) is greater than that of the flywheel (52). In addition to the belt, the present invention can also utilize a gear set (not shown) as the aforementioned acceleration transmission mechanism. The two-link assembly (6〇) is located on the left and right sides, respectively, and is connected to the pedal group (30) of the corresponding side and the crank arm (42) of the winding mechanism (4〇). In this embodiment, each link assembly (60) includes a swing arm (61), a sub-arm (62) and a linkage rod (63), wherein the swing arm (61) pivots one end (top end) Connected to the side frame (14) of the frame body (10), so that the other end (bottom end) can swing forward and backward along a circular arc track outside the guide rail (20); one end (front end) of the auxiliary arm is connected to the swing arm The inner side of the bottom end of (61), the other end (rear end) is spliced to the predetermined position of the outer side plate (36) of the step 12 1272955 =, , and (30); one of the interlocking rods (63) The other end (the rear end) of the crank arm (42) pivotally connected to the outer side of the crank arm (42) of the rewinding mechanism (4〇) is pivotally connected to the inner side of the middle section of the swing arm (61), The axes of the pivotal structures are both left and right axial.

Therefore, because the one-turning stroke of the crank arm (42) is engaged with the swinging stroke of the swing arm (61), the swinging stroke of the swing arm (61) is in turn implicated with one reciprocating stroke of the pedal group (30). Cooperating, the pedal group (3〇)_ and the rewinding mechanism (40) are interlocked with each other. Wherein, based on the two-way wrap (44), the rotation is repeated 180 degrees relative to a circular trajectory (the rotation is not restricted), so the left and right two pedal groups (3 〇) will exhibit an equal amount of reverse displacement. That is, one of the pedal sets (30) descends a predetermined distance backward, forcing the other pedal group (30) to rise forward by the same distance, and when one of the pedal sets (3〇) is behind the motion track At the turn-back point, the other pedal set is just at the front turnback point of the motion track. The hand motion mechanism (70) comprises left and right yaw bars (71) and left and right reciprocating links (72), each yaw bar (71) is arranged substantially longitudinally, and the shaft is approximately centrally The parts are pivoted to the side of the uprights (12) of the frame body (10) in the left and right directions so that they can be yawed back and forth. One end (front end) of each reciprocating rod connection (72) is pivotally connected to the bottom end of the yaw lever (71), and the other end (rear end) is pivotally connected to the outer side of the intermediate section of the swing arm (61) of the corresponding side; The axes of the two splicing structures are both left and right axial. Thereby, the lower half of each yaw lever (71) can swing back and forth in synchronization with the swing arm (61) of the same side, and because the swing end of each swing arm (61) is corresponding to the pedal group (30) - with forward or backward, so that the top of the yaw lever (71) for the user to grasp the grip (73) will be the same side 13

1272955 The pedal group (30) moves in the opposite direction, meaning that when the left pedal set (30) is displaced forward along the guide rail (20), the left grip (73) will follow an arc (the center of the circle below) toward Post displacement; vice versa. In the illustration, the grip (73) at the top end of the yoke (71) is designed as a transverse shank, and can also be designed as a longitudinal shank or other shaped grip for the user to grasp. With the above structure, the user can perform the up and down coordinated body movement using the aforementioned exercise equipment. When in use, the user steps on the left and right two: | pedal (34), and holds the left and right grips (73) with both hands, and applies the force to the pedals when the feet and hands are used. And the grips (73) are respectively driven along the movement path, and are driven by the connection of the rewinding mechanism (40), the link assembly (6〇) and the hand movement mechanism (70), as described above, left and right The pedals (34) will reciprocate back and forth on the tilting track in the opposite direction to each other, and the left and right two grips (73) will also reciprocally reciprocate back and forth on the curved track in opposite directions to each other, and the same side The grip (73) and the pedal (34) are in a reverse motion, as illustrated in the second and seventh figures. In the lower part of the body, the user acts as if there is a movement between the slide machine and the stepper, that is, the feet are forced to each other and reciprocally slip in the opposite direction of the straight line. This simulates alternate leg movements like mountain climbing and climbing. In the upper part of the body, the user's hands can be coordinated with the feet, not only to expand the body movements, improve the amount of body movement, but also the four (4) in line with the human body walking, running balance, more natural and comfortable. (d), the present invention can also be placed in the appropriate position of the frame (10), such as the left pole (10) or the left and right two side frames ((4), set the fixed handrail (not shown), so that the user can choose Catch your hands 14

Ϊ 272955 On the aforementioned armrests, only the lower body movement is performed. It is worth mentioning that, in the pedals of sports equipment such as steppers or elliptical machines, the angle of the supporting surface is forced to change cyclically with the movement stroke, so that the ankle joint of the user must correspond to the movement, and if the angle change is poorly set, It may cause burden and injury to the ankle; however, in the above embodiment of the invention, the pedal (34) is always maintained at a certain angle during the slipping process, so that the burden of the ankle is light. Of course, the present invention does not limit the angle of the pedal relative to the guide rail. For example, an elastic member may be disposed at the bottom of the rear end of the pedal to be elastically floatable, or the pedal may be deflected by the link assembly so as to have different angles at different positions. . Those skilled in the art will appreciate that the linkage assembly and the hand movement mechanism can achieve similar effects using other configurations, for example, each side is directly coupled to the rewinding contact and the pedal group by a linkage rod (not shown) (shown), the left and right crank arms can be interlocked with the left and right pedal groups; however, the connection of the upper swing arm (61), the jib (62) and the linkage lever (63) can be transmitted through Under the same swing angle, the swing arm (61) has a larger swinging effect farther from the center of the circle, so that the movement stroke of the pedal group (30) can be moderately larger than the diameter of the circular track of the rewinding joint (44); In other words, the aforementioned sports equipment can provide sufficient pedal travel without the need to configure a long crank arm. Similarly, if the reciprocating link in the hand movement mechanism is directly coupled between the bottom end of the yaw lever and the pedal group (not shown), although the effect of the reverse linkage between the handle and the pedal can be achieved, In the embodiment, the rear end of the reciprocating link (72) is pivotally connected to the intermediate section of the swing arm (61) in order to set the yaw amplitude of the handle (73) to a more appropriate range. 15

1272955 The flywheel (52) is suitably sized from metal and has a certain degree of weight. The user must have sufficient force to drive the flywheel (52) to rotate. At the same time, the flywheel (52) generates a predetermined inertia when it is rotated. This inertia is amplified to the rewind mechanism (4G) through the transmission belt (56), and then through the linkage assembly (60) and the hand movement mechanism (7〇). Conducted to the pedal (34) and the grip (73), so that the reciprocating motion of the pedal (34) and the grip (73) can obtain a motion inertia, which is relatively stable and smooth during the movement. The sports equipment of the present invention may also be provided with a resistance device for providing additional resistance, for example, a conventional "eddy-current brake (ECB)" (not shown) is disposed beside the flywheel (52). As is conventional in sports equipment, the eddy current brake has a movable magnetic component through which the user can electronically control the positional relationship of the magnetic component relative to the flywheel (52). Thereby, the rotation resistance of the flywheel (52) is adjusted, that is, the movement resistance of the pedal (34) and the grip (73) is indirectly changed to achieve the purpose of setting the movement difficulty. (Note: The basic structure and principle of the foregoing eddy current brake are known in the art and will not be described here.) As described above, in the present embodiment, the guide rail (20) is disposed on the frame in an angularly adjustable manner (1) 〇), more specifically, the left and right guide rails (20) are fixed by a front connecting rod (21) and a rear connecting rod (22) to maintain parallelism, and the rear connecting rod ( 22) The left and right axial ends are connected to the rear end of the base (11) of the frame body (10) so that the left and right two guide rails (20) can be simultaneously pivoted with their rear ends (21) as the axis. At the same time, an angle adjusting device (90) is disposed between the front end of the guide rail (20) and the frame base (11) below, and the adjusting device (90) is substantially a motor group (91), a screw (92) and a solenoid (93) 16 I272955, wherein the 'motor unit (91) further includes a motor base pivotally mounted on the base (ii) of the frame, a motor disposed on the motor base, and a gear box;

(92) Coaxially sew with the solenoid (93) to form a "telescopic rod". One end (in this case, the screw cup (92)) receives the gearbox output shaft of the motor unit (91), and the other end (in this case, the solenoid) (93)) The front connecting rod (21) pivotally connected to the front end of the left and right second guides (20). The console (9〇) can control the motor operation of the motor unit (91). When the motor rotates in a certain direction through the gearbox drive screw (92), since the screw (93) cannot rotate according to its own axis, the screw (93) cannot rotate according to its own axis. The screw (92) and the solenoid (93) will be relatively far apart (that is, the "longitudinal extension"), so that the front end of the guide rail can be pushed up; otherwise, when the motor drive screw (92) is rotated in the other direction When rotating, the screw (92) and the solenoid (93) will be relatively close (ie, the "teling rod" is shortened), so that the front end of the guide (2〇) can be pulled downward; when the motor stops, the screw (10) and the screw The tube (10) is relatively locked so that the guide (10) is firmly positioned at the current angle.

Based on the preset "teling rod" stroke range, the guide (2〇) can be named as the first angle (maximum elevation angle) shown in the second figure and the second angle (minimum elevation angle) as shown in the eighth figure. deflection. In practice, the guide rails (the slope can be designed to be variable in the variable _ no segment, or only a certain angle between them). The user can set the guide (10) according to the individual situation. Obviously, under the premise of the same resistance, when the elevation angle of the guide (2G) is smaller, the leg movement is easier. Conversely, when the elevation angle of the guide (20) is larger, the leg movement is more difficult. Of course, as the current popular H-boats are used, (4) (4) can adjust the inclination of the guide rail (10) during the movement process, and can also select the wire type, so that the machine automatically changes the guide rail according to the preset timing during the movement of the 17 1272955 movement ( 20) Slope, such as gradual increase, high and low alternation, etc., can improve the variability and fun of the movement. Moreover, the function of adjusting the inclination of the guide rail (20) can be adjusted with the function of adjusting the rotational resistance of the flywheel (52). Coexisting with each other, providing a wider variety of exercise programs for users to choose from.

Finally, it must be added that the structure or the use of the sports equipment shown in the above and the drawings, especially the guide, the rewinding mechanism and the hand movement mechanism, are only one of the preferred embodiments of the present invention. It is not intended to limit the scope of possible implementation of the invention. For example, in other embodiments of the present invention, the guide rail may be a guide pedal that moves forward and backward along an arc, and the guide does not limit the front end to be higher than the rear end, that is, may be set to be substantially horizontal or even front end. Lower form. Moreover, the relative two cranks are the simplest way to achieve the aforementioned rewind mechanism, but the present invention does not exclude the use of other mechanisms to provide rewind contacts that can move over circular, elliptical or other similarly shaped closed tracks. 18 1272955 [Brief Description of the Drawings] The first drawing is a perspective view of a preferred embodiment of the present invention; the second drawing is a left side view corresponding to the state of the first figure of a preferred embodiment of the present invention (for the sake of convenience, in the figure) The third embodiment is a top view of a preferred embodiment of the present invention corresponding to the first state, and the fourth embodiment is a front view of a preferred embodiment of the present invention corresponding to the first state;
