The grasping grip (42) can be the first The axis (X1) is moved around a circle to form an operation unit for the movement unit (40) in the present embodiment for the user to operate.

Please refer to FIG. 5 again, the fixing column (12) of the main frame body (10) is arc-shaped, the upper half protrudes obliquely forward, and a longitudinally extending fixing tube (14) is welded at the top end. The fixed tube (14) has a tip end and a bottom end, and the angle between the axis (Y1) and the vertical line (perpendicular to the ground) is about 7.5 degrees. The reversing frame body (20) is substantially in the arc concave space in front of the fixing column (12), and is generally elongated in shape as a whole, and is suspended from the top end of the fixing column (12), and the top end thereof is fixed according to the aforementioned fixing tube ( The axis (Y1) of 14) is pivotally connected to the fixed pipe (14) (detailed after structure). Further, the inversion frame body (20) is composed of a metal material backbone (21) and a plastic material cover (22). The top end of the backbone (21) is formed coaxially with the fixed tube (14) and has an outer diameter equal to The cylindrical portion (211) has a laterally penetrating shaft tube portion (212) below. When the reversing frame body (20) is fixed relative to the main frame body (10) in a state as shown, the axis of the aforementioned shaft tube portion (212) (hereinafter referred to as a second axis) (X2) is parallel to the ground, and Corresponds to the left and right axial directions.

The entire displacement frame body (30) is also substantially elongated (note: in the state of the figure; actually may be rotated into a substantially horizontal shape, which will be described later), including the vertical plate-shaped portion and the position relative to the lower position. In the upper horizontal cylindrical portion, which is also composed of a metal backbone (31) and a plastic cover (32), the bottom end of the backbone (31) is fixed to a laterally projecting shaft cylinder (33), and the shaft cylinder ( 33) coaxially pivoting in the shaft tube portion (212) of the reversing frame body (20), and attaching the vertical plate portion of the displacement frame body (30) to the top side of the reversing frame body (20) (illustration The right side of the state), the horizontal cylindrical portion of the top is roughly at the center of the width of the sports equipment, overall The deflection can be performed with respect to the reversing frame body (20) according to the aforementioned second axis (X2).

Next, please refer to Figures 6 to 8 (Note: Among them, in Parts 6, 7, remove the partial frame cover (32, 22) of the displacement frame body (30) and the reverse frame body (20), so as to present the internal structure) The moving unit (40) further includes a crank shaft (43) laterally pivoted on the top end of the displacement frame body (30) according to its own axis, and the two cranks (41) are perpendicular to the crank shaft (43) in respective long axes. The inner end is connected to the opposite ends of the crank shaft (43) in an axial manner, so that the axis of the crank shaft (43) can be rotated relative to the displacement frame body (30), in other words, the crank shaft (43) The axis constitutes the aforementioned first axis (X1). The first axis (X1) on the displacement frame body (30) is parallel to the aforementioned second axis (X2), and corresponds to the left and right axial directions in the operation mode as shown, so that the two cranks (41) and the two grips are Place (42) on the left and right sides for the user to hold the left and right hands.

Different from the crank and the crank shaft in the general crank mechanism, the crank (41) is connected to the crank shaft (43) in a manner that can only be driven in one direction, and more specifically, each crank (41) is Connected to the crankshaft (43) through a one-way bearing (44) (see Figure 8), so that the crank (41) can be reversed relative to the crankshaft (43) (corresponding to the inverse clock from the perspective of Figure 4) Direction), but cannot be rotated forward relative to the crankshaft (43) (corresponding to the clockwise direction at the perspective of Fig. 4), and at the same time, each crank (41) can be independently positioned on the circumference with respect to the crankshaft (43). At any angle, the aforementioned two cranks (41) are not pinned. Thereby, when the user operates the grip (42) to perform the hand movement, the left and right cranks (41) can be driven as desired, that is, the two cranks (41) may be synchronized/unsynchronized, in phase/different. Rotating together or separately, and driving the crank (41) to rotate forward in the direction of motion S in Fig. 4 can drive the crankshaft (43) in the same direction Rotation (Note: Strictly speaking, the torque of the crank (41) is transmitted only when the forward rotation rate of the crank (41) relative to the displacement frame (30) is not lower than the forward rotation rate of the crankshaft (43). To the crankshaft (43)), the crankshaft (43) is unaffected when the crank (41) is stationary or reversed.

The structure and function of the aforementioned one-way bearing (or one-way clutch) are conventional techniques, such as "freewheel" in the general bicycle crank system. Furthermore, the foregoing two left and right cranks are respectively connected to the crankshaft through a one-way bearing, so that the cranks can be independently rotated (unlike the left and right cranks of the conventional bicycle are maintained at 180 degrees), which is also a conventional technique. For example, there is a related disclosure in the prior publication of U.S. Patent No. 7,530,932 or U.S. Patent Application Serial No. 2009/056,371.

A shaft (45) is coaxially disposed at a center of the shaft barrel (33) at the bottom end of the displacement frame body (30), and a bottom end of the reverse frame body (20) is provided with a mandrel parallel to the transmission shaft (45) ( 46), the mandrel (46) is coaxially sleeved with a tube shaft (47), and the tube shaft (47) is coaxially fixed to a flywheel (48); one end of the crank shaft (43) is coaxially fixed to the first a sprocket (51), the opposite ends of the transmission shaft (45) are coaxially fixed to a second sprocket (52) and a third sprocket (53), wherein one end of the tube shaft (47) is coaxially fixed a fourth sprocket (54); the first sprocket (51) has a larger diameter and a larger number of teeth than the second sprocket (52), and a first chain (55) is looped between the two (51) (52); The third sprocket (53) has a larger diameter and a larger number of teeth than the fourth sprocket (54), and a second chain (56) is looped between the two (53) (54). Thereby, when the crankshaft (53) is driven by the user and rotates in place, the flywheel (48) is driven by the first and second chains (55, 56) according to the aforementioned mandrel in a two-stage transmission manner ( The axis of 46) (hereinafter referred to as the third axis) (X3) Several times the speed is turned in place. However, the rotational inertia of the flywheel (48) is also transmitted back to the crankshaft (53). The above two-stage transmission is interposed by a transmission shaft (45) positioned on the pivot axis (ie, the second axis (X2)) of the displacement frame body (30) and the reversing frame body (20), regardless of the displacement frame body. (30) The aforementioned transmission can be carried out with respect to the angle to which the reversing frame body (20) is deflected.

As above, the flywheel (48) is rotated by the high speed ratio to form the main motion resistance of the user operating the aforementioned motion unit (40). In this embodiment, the reverse frame body (20) is further provided with a friction block (57) above the flywheel (48), and at the same time, the top end of the displacement frame body (30) is provided with an adjustment for the user to twist in both directions. The knob (58), when twisted, can be controlled by a cable (59) to force or float the friction block (57) around the circumference of the flywheel (48) to adjust the magnitude of the aforementioned motion resistance. The above-mentioned adjustable resistance device using the flywheel with the friction block belongs to the well-known conventional technology of the similar or related sports equipment (for example, a sports bicycle, a rowing machine, etc.), so only a brief description will be given here. It must be stated that the aforementioned flywheel (48) also constitutes a resistance device for the motion unit (40) even without the aforementioned friction block (57). In addition, the motion unit in the present invention can of course adopt various conventional adjustable or non-adjustable resistance devices such as magnetoresistance, wind resistance, water resistance and the like.

Next, the detailed structure and operation mode of the displacement frame body (30) which can be deflected and positioned with respect to the reversing frame body (20) according to the lateral axis will be described.

As shown in FIG. 5, the backbone (21) of the reversing frame body (20) is fixed with a circular arc shape centering on the second axis (X2) and surrounding the upper half of the shaft tube portion (212). a fitting (61) (which is a part of the reversing frame body (20)), the fitting member (61) having a plurality of concaves arranged equiangularly toward the inner circumference of the center of the circle Wo (611). Please refer to Figures 10 and 11 together. In this embodiment, there are a total of thirteen aforementioned dimples (611), and the angular distance between the centers of adjacent dimples (611) is about 12 degrees, that is, the fitting The piece (61) is spaced about 144 degrees from the two dimples (611) at the two ends. Each of the dimples (611) is gradually narrowed and recessed by the arcuate inner peripheral surface of the fitting member (61) in the radial direction of the center of the circle while being gradually narrowed away from the center of the circle, and the concave portion is slightly triangular or semi-circular, having a position The wider end and the narrower end in the aforementioned radial direction, and the opposite two side wall faces (612) on the circumference corresponding to the aforementioned center (see Fig. 17). Further, the dimples (611) are open to the side (hereinafter referred to as the front surface) of the displacement frame body (20). Essentially, the arrangement of the dimples (611) corresponds to the displaceable direction of the displacement frame body (30) relative to the reversing frame body (20), and the opposite side wall faces in each dimple (611) (612) is opposite to each other in the aforementioned displaceable direction.

On the other hand, on the backbone (31) of the displacement frame body (30), a pressing member (62) (which is a part of the displacement frame body (30)) is fixed above the shaft barrel (33), and its position is adjacent to the aforementioned inlay. The inner peripheral surface of the circular arc of the fitting (61). As shown in Figures 12 to 14, the pressing member (62) has a tapered recess (621), and the tapered recess (621) is substantially recessed by the pressing member (62) toward one side of the fitting member (61). The V-shaped groove is penetrated from the front surface of the pressing member (62) to the back side, and the concave depth of the tapered recess (621) is from the end corresponding to the front surface (below) The first end) is gradually shallower toward the end of the corresponding back surface (hereinafter referred to as the second end). Thus, the tapered recess (621) forms a relatively two forced inclined surface (622) in the displaceable direction, and each forced inclined surface (622) ) from the first end to the second end, from bottom to top, from both sides to the center. Wherein the connecting direction of the first end and the second end is parallel to the second axis (X2) (in other words, perpendicular to the aforementioned displaceable direction), and the so-called "from bottom to top" is merely a general statement of the state of the figure, strictly speaking, the radial direction of the second axis (X2) is far from the second. Axis (X2).

Meanwhile, as shown in FIG. 9a, the backbone (31) of the displacement frame body (30) has a constant hole (311) at a position corresponding to the aforementioned tapered recess (621), and its through direction is parallel to the second axis (X2). And the hollow portion corresponds to the front side of the tapered recess (621) and the recess (611). In addition, a support frame (34) (as part of the displacement frame body (30)) is disposed on the outer side of the through hole (311) facing away from the reversing frame body (20), and the outer side plate surface of the support frame (34) has A perforation (341) spaced apart from the through hole (311). An elongated caulking member (63) is interposed in a connecting direction of the through hole (311) and the through hole (341), and the caulking member (63) has a rod-shaped body axially corresponding to the through hole (311). 631), and a cylindrical head portion (632) coupled to the body portion (631) closer to one end of the reversing frame body (20), the whole body can be displaced along the through-direction in the displacement frame body (30), and Since the inner diameter of the through hole (311), the through hole (341) and the outer diameter of the head (632) of the plug member (63) and the outer diameter of the body portion (631) are respectively reserved, the stopper (63) It is also possible to shift in the direction perpendicular to the aforementioned through direction (corresponding to the radial direction of the second axis (X2)).

In addition, a resilient pushing member (64) is disposed between the blocking member (63) and the displacement frame body (30), and the protruding member (63) is provided to protrude into the reverse frame body (20) along the through-direction. With appropriate thrust, the elastic pushing member (64) in this embodiment adopts a helical compression spring which is sleeved on the body (631) of the plug member (63), and one end of the axial direction abuts against the body of the plug member (63). An annular shoulder surface between the portion (631) and the head portion (632), and the other end abuts against the outer side surface of the support frame (34).

As shown in Figures 12 and 15, 16, the bottom side of the head (632) of the plug member (63) has a slanted abutting surface (633), and each abutting surface (633) is a head (632). The outer end surface is tapered toward the body (631) direction and simultaneously from the axial direction to the outer circumferential direction, and the relative angle of the two abutting surfaces (633) corresponds to the two pressing slopes of the tapered recess (621) (622) The relative angles of the two abutting faces (633) can be respectively applied to the two pressing inclined faces (622), and the relative slipping relationship can be maintained. In addition, the top side of the head (632) forms a cylindrical abutting surface (634).

Thus, the recess (611), the tapered recess (621), the constricting member (63) and the elastic pushing member (64) constitute a fixed displacement frame body (30) opposite to the reversing frame body (20). A displacement locking device (60) of the relationship, that is, as illustrated in Figures 10 and 11, when the tapered recess (621) on the displacement frame body (30) is engaged with any of the reverse frame bodies (20) When the dimple (611) is recessed, the constricting member (63) pushed by the elastic pushing member (64) will be constricted at the front end of the head (632) to the conical recess (621) and the corresponding dimple (611). In more detail, as shown in Figures 9a and 17, the opposing two abutting faces (633) on the bottom side of the head (632) are respectively adhered to the opposite sides of the tapered recesses (621). The second inclined surface (622), and the card abutting surface (634) on the top side of the head (632) simultaneously snaps against the opposite side wall surfaces (612) of the recess (611), thereby, because of the congestion member (63) It is impossible to displace in the aforementioned displaceable direction with respect to the pressing member (62) or the fitting member (61), so that the displacement frame body (30) cannot be deflected relative to the reversing frame body (20) in the aforementioned displaceable direction.

As shown in Fig. 9a, the plug member (63) is additionally inserted by a pin (68) through a radially extending pin hole (635) in the head portion (632) (see Fig. 16), the aforementioned pin (68). The end of the deflector is loosely received in the oblong hole (672) of a deflecting member (67) The deflecting member (67) is pivotally connected to the backbone (31) of the displacement frame body (30) through a pivot (671) parallel to the latch (68), as illustrated in Figures 9a and 9b. Limited deflection. On the other hand, as shown in FIGS. 6 and 8, the top end of the displacement frame body (30) is provided with a control ring (65) surrounding the horizontal cylindrical portion between the left and right cranks (41), and is controlled. The bottom of the trigger ring (65) is pivotally connected to the displacement frame body (30) by a pivot (651) perpendicular to the first axis (X1), and the top portion is horizontally pluckable by the user. Inside the cover (62) of the displacement frame body (30), a cable (66) is tightly coupled between the control ring (65) and the predetermined portion of the deflecting member (67) when the displacement locking device (60) is in the In the locked state shown in Fig. 9a, the deflecting member (67) which is mutually restrained with the caulking member (63) is positioned at the first angle, and the upper control ring (65) is pulled through the aforementioned cable (66). The angle is as shown in Figure 8. When the user pulls the top of the control trigger ring (65) to the side away from the deflecting member (67) (the left side in Fig. 8), the deflecting member (67) is deflected by the cable (66) pulling upward. Forming a second angle as shown in Fig. 9b, and forcing the caulking member (63) (resisting the elastic force of the elastic pushing member (64)) through the pin (68) substantially along the through hole (311) The direction is moderately away from the reversing frame body (20), so that the front end of the head (632) of the constricting member (63) is withdrawn from the front surface of the dimple (611), but the abutting surface (633) is still partially offset from the pressing bevel (622). .

When the user maintains the displacement locking device (60) through the control loop (65) in the untwisting state as shown in FIG. 9b, the displacement frame body (30) is aligned with respect to the second axis (X2). The reversing frame body (20) is deflected. When deflected, the pressing member (62) on the displacement frame body (30) moves along the circular arc-shaped inner side surface of the fitting member (61) on the reversing frame body (20) to make the cone of the pressing member (62) Indentation (621) facing different portions of the inner side of the fitting (61), such as different dimples (611). Referring to FIGS. 10 and 11, the opposite ends of the fitting member (61) each have a deflection limiting portion (613) protruding outward in the center of the recess (611) to block the pressing member. (62) A side surface corresponding to the aforementioned displaceable direction, thereby limiting a deflection range of the displacement frame body (30) with respect to the reversing frame body (20). In this embodiment, when the pressing member (62) is blocked by the deflection limiting portion (613) at either end of the fitting member (61), the tapered recess (621) of the pressing member (62) will just coincide. The dimple (611) closest to the end of the fitting (61), in other words, the deflectable range of the displacement frame (30) relative to the reversing frame (20), is approximately 144 degrees as previously described.

When the user rotates the displacement frame body (30) to the vicinity of the desired angle according to the second axis (X2), the control loop (65) can be released, and the plug member (63) is again subjected to the elastic pushing member. (64) pushing in the direction of the reversing frame body (20). At this time, if the conical recess (621) on the displacement frame body (30) is engaged with one of the dimples on the reversing frame body (20) (611) (Note: if necessary, the displacement frame body (20) should be deflected slightly forward or backward), and the front end of the head (632) of the plug member (63) will follow the tapered recess (621). From the front side of the corresponding recess (611), it is forced into the recess (611), as shown in Fig. 9b to change to Fig. 9a. During the process, due to the restriction and guidance of the forced bevel (622), when the constricting member (63) is subjected to the elastic force of the elastic pushing member (64), the direction of the first end of the corresponding conical recess (621) is toward When the direction of the second end (corresponding to right to left in Fig. 9a) is fed, it will be away from the second axis (X2) in the radial direction of the second axis (X2), equal to the corresponding dimple (611). The wider end is urged toward the narrower end (corresponding to the bottom-up in Figure 9a) until the plug (63) remains in its opposite The two abutting faces (633) are respectively attached to the opposite two-forced inclined faces (622) of the pressing member (62), and the engaging faces (634) are simultaneously engaged against the opposite side wall faces of the corresponding recesses (611) (612). As described above, the plug member (63) is not displaceable in the aforementioned displaceable direction with respect to the pressing member (62) or the fitting member (61), so that the displacement frame body (30) cannot be displaced along the aforementioned direction. The direction is deflected relative to the reversing frame body (20).

Therefore, as shown in FIG. 4, when using the hand exercise equipment of the embodiment, the user can rotate and position the displacement frame body (30) according to the individual body shape, usage habit or desired motion posture. In order to adjust the front-rear distance or height of the operating portion (ie, the aforementioned grip (42)) of the aforementioned moving unit (40) relative to the aforementioned seat group (13), the sports equipment exhibits different operational modes. In the present embodiment, based on the aforementioned configuration of the dimples (611), the caulking members (63) on the displacement frame body (30) are fitted to the dimples on the reversing frame body (20) ( 611) in the center of one (as shown by the solid line in Fig. 11), the displacement frame body (30) is substantially upright (as shown by the solid line in Fig. 4), and the displacement frame body (30) can thereby The position is deflected by up to 72 degrees forward or backward, and is available for selection every 12 degrees.

In the upper displacement locking device (60), since the symmetrical two abutting surface (633) of the constricting member (63) is always in close contact with the symmetrical two pressing inclined surface (622) of the pressing member (62), the congestion is caused. The central surface of the member (63) and the pressing member (62) (symmetrically separating the abutting surface (633) and the pressing inclined surface (622)) are always coplanar, so that the blocking member (63) is completely unable to be in the pressing member (62). The upper displacement frame body (30) is displaced relative to the displaceable direction of the reversing frame body (20). Secondly, by pressing the inclined guide of the inclined surface (622), the plug member (63) is gradually pushed toward the tapered recess (621). At the same time as the second end, it will gradually squeeze toward the narrower end of the dimple (611). (Note: During this process, the constricting member (63) may force the dimple (611) to slightly deflect in the aforementioned displaceable direction to align with each other. Or, rather, a relatively fixed dimple (611) forcibly deflecting the deflecting member (63) and the pressing member (62) together with the pressing member (62) until the engaging portion of the constricting member (63) (634) Simultaneously snapping against the opposite side wall faces (612) in the recess (611), so that the plug member (63) is also completely displaceable on the fitting member (61) in the aforementioned displaceable direction, whereby the shift frame The body (30) and the reversing frame body (20) do not have any play in the displaceable direction, so there is no phenomenon of biasing and loosening.

In the present embodiment, the above-mentioned squeezing action of the squeezing member (63), if possible, also causes the fitting member (61) and the pressing member (62) to be relatively far apart from each other in the radial direction of the second axis (X2). It is no longer possible to move away, and the fitting member (61) and the pressing member (62) are relatively far apart from each other in the axial direction of the second axis (X2) to be further away from each other. In other words, the above-mentioned congestion action can eliminate the displacement frame body at the same time. (30) radial play and axial play (if any) of the pivotal joint with the reversing frame body (20), so that the displacement frame body (30) and the reversing frame body (20) are in all sides There is no relative displacement gap in the upward direction, and it can be relatively firmly fixed.

Under the technical idea of the present invention, the mating structure between the plugging member and the tapered recess may have other embodiments, and is not limited to the front symmetrical two inclined surface. For example, the inner wall surface of the tapered recess may not be Symmetrical opposite slanted faces, possibly with multiple slanted faces (note: partial like a polygonal facet), may also be a conical surface (note: a partial surface similar to a cone), but the common feature is that the concave portion is from the foregoing The first end gradually narrows and becomes shallower toward the second end, that is, the "tapered shape" is present; as for the shape of the abutting surface of the plugging member, as long as In conjunction with the integral or partial inner wall surface of the tapered recess, when the constricting member is engaged with the conical recess, a central surface of the constricting member can be coplanar with a central surface of the conical recess, even if the concealing member It is not possible to displace in the aforementioned displaceable direction with respect to the tapered recess.

Of course, the technical means of the displacement locking device of the present invention can be suitably applied between the first and second frames of the various sports equipment that can be relatively displaced, so as to cooperate with various sports equipments for adjusting the operation mode. demand. In other embodiments of the present invention, depending on the type of the sports equipment, the support unit is used to support the support portion of the user, or the operation unit for the user to operate the motion unit may have a different type from the above-described embodiment. But the basic use is the same as above. In addition, the relative displacements of the first and second frames are not limited to the relative deflection according to the pivot axis, and may be, for example, a relative displacement along a straight line or a specific route. For example, a similar example is disclosed in US Pat. No. 7,530,932. The adjustable seat in the patent, that is, the structure in which the seat post (the first frame body) can be linearly moved up and down along a fixed pipe (the second frame body), if the invention is applied, the upper and lower seat pillars can be lifted and lowered Aligning a plurality of the aforementioned dimples arranged in a straight line, and arranging the conical recesses, the caulking members and the elastic pushing members at appropriate positions of the fixing tube, when the user directly pulls or indirectly controls the caulking member to be separated from the concave portion. When the socket is seated, the seat post can be linearly lifted relative to the fixed pipe to change the height of the seat supported by the seat. After the proper position, the plug member is squeezed between the tapered recess and the corresponding recess, so that the seat is opposite to the corresponding recess. The fixed tube is firmly fixed.

Continuing with the above, the detailed structure and operation mode of the reversing frame body (20) which can be reversed and positioned with respect to the main frame body (10) according to the longitudinal axis will be described. Different from the aforementioned displacement locking device (60) between the displacement frame body (30) and the reversing frame body (20), a controllable second is additionally provided between the reversing frame body (20) and the main frame body (10). The reverse locking device (not labeled) of the relative relationship between (20) and (10) is explained below.

Referring to Figures 18 to 21, the aforementioned fixed tube (14) at the top end of the fixing post (12) of the main frame body (10) is coaxially fixed at its top end nozzle with a ring-shaped tube end piece (15) (considered a part of the fixed pipe (14), the annular top surface of the pipe end piece (15) is provided with an elastic support member (74) having an elastic force extending in the axial direction of the fixed pipe (14), and the elastic support in this embodiment The member (74) employs a conical disc-shaped disc spring (or disc spring) as shown in Fig. 22. The top side of the elastic support member (74) is additionally laminated with an annular support plate (73). The support plate (73) is balancedly supported by the elastic support member (74), and the top surface is parallel to the diameter of the fixed tube (14).

The reversing frame body (20) is locked on the aforementioned cylindrical portion (211) at the top end of the backbone (21) by a bolt (25) to lock a shaft (23) which protrudes upward along the axis of the cylindrical portion (211). And a part of the reversing frame body (20), and the shaft rod (23) is coaxially pivoted through the fixing tube (14) of the main frame body (10), so that the reversing frame body (20) can be fixed according to the fixing tube (14) The axis (Y1) is rotated relative to the main frame body (10). In the present embodiment, the axis (Y1) of the fixed pipe (14) passes downward through the aforementioned second axis (X2) of the reversing frame body (20), and the intersection point corresponds to the center of the length of the aforementioned shaft tube portion (212). In other words, when the reversing frame body (20) is rotated according to the axis (Y1) of the fixed pipe (14), the center position of the shaft tube portion (212) of the reversing frame body (20) is opposite to the main frame body (10). Keep it still.

The top end of the shaft (23) protrudes through the aforementioned annular support plate (73) and locks a cap (23) of the cover shaft (23) beyond the portion of the fixed tube (14). In addition, The top end of the shaft (23) has a cylindrical cross hole (231) penetrating in the radial direction, the transverse hole (231) is fitted through a torsion bar (71), and the torsion bar (71) protrudes from the shaft (231). The opposite ends of the two sides respectively pivot a roller (72), and the bottom side of the circumferential surface of the two rollers (72) is pressed against the top surface of the support plate (73). Thereby, the torsion bar (71) is supported above the fixed tube (14) by the two rollers (73), and then the top end of the shaft (23) is suspended by itself, so that the shaft (23) cannot be pulled down and fixed. Tube (14).

The two rollers (72) have the same diameter, the connecting line of the center defines the main axis of the torsion bar (71), and the portion of the torsion bar (71) that is fitted into the transverse hole (231) forms an axis deviation. The cylindrical eccentric portion (711) of the main axis, the outer diameter of the eccentric portion (711) is appropriately matched with the inner diameter of the cylindrical transverse hole (231), and can depend on the axial center of the transverse hole (231) relative to the shaft (23) The rotation is performed, and the outer peripheral surface of the top side thereof is supported by the top side of the inner peripheral surface of the lateral hole (231). One end of the torsion bar (71) is exposed by a side hole (241) of the aforementioned cap (24), and is fixed to a control twist (75) to form a U-shape, when the user turns the position. When the twist handle (75) is controlled outside the cap (24), the torsion bar (71) pivoted between the two rollers (72) can be rotated according to the aforementioned main axis. When the torsion bar (71) rotates, the eccentric portion (711) is eccentrically rotated with respect to the main axis, so that the outer peripheral surface of the eccentric portion (711) is farther from the main axis (hereinafter referred to as the thick side) and The near side (hereinafter referred to as the thin side) is deflected and deflected with the main axis as a center. Thereby, in general, since the height of the main axis of the torsion bar (71) with respect to the fixed pipe (14) is substantially constant, when the thick side of the eccentric portion (711) of the torsion bar (71) faces upward, the torsion bar (71) will lift the shaft (23) in a relatively high position, and conversely, when the thin side of the eccentric portion (711) faces upward The shaft (23) is then suspended in a relatively low position.

The torsion bar (71) is additionally sleeved and fixed with a torsion limiting member (76) as shown in Fig. 23. The torsion limiting member (76) has a relative locking of the top surface of the supporting plate (73). The surface (761) is such that the twistable angle of the torsion bar (71) is limited to the two states shown in Figs. 25a and 25d (i.e., the locking surface (761) abuts against the top surface of the support plate (73). Between states). In the state of Fig. 25a, the thick side of the eccentric portion (711) is above; in the state of Fig. 25d, the thin side of the eccentric portion (711) is above; that is, the torsion bar (71) It can be twisted up to about 180 degrees (Note: in order to easily recognize the torsion angle of the torsion bar (71), the longest outer diameter of the outermost surface of the eccentric portion (712) farthest from the aforementioned main axis is indicated in the 25a to 25d figures. (712)).

In normal times, the reverse locking device between the reversing frame body (20) and the main frame body (10) exhibits a locking state as shown in Figs. 20, 21 and 25a, that is, the aforementioned torsion limiting member (76). One of the locking faces (761) abuts against the top surface of the support plate (73), and correspondingly, the thick side of the eccentric portion (711) of the torsion bar (71) is substantially upward, so that the reversing frame body (20) is pushed The top end of the cylindrical portion (211) of the reversing frame body (20) abuts against the bottom end surface of the fixed pipe (14), and the cylindrical portion (in more detail) 211) a predetermined two-wedge convex portion (213) on the top end surface is fitted into a predetermined opposite wedge-shaped concave portion (141) on the bottom end surface of the fixed tube (14) (refer to Figs. 18 and 19), so that the reverse The frame body (20) cannot be rotated according to the aforementioned axis (Y1). Incidentally, the aforementioned elastic support member (74) in this state has not been pressed to the limit of elastic deformation.

The user twists the torsion bar (71) according to the main axis by controlling the twisting handle (75) until the other locking surface (761) of the torsion limiting member (76) abuts the supporting plate. (73) During the top surface, as the thick side of the eccentric portion (711) gradually turns downward and the thin side gradually turns upward, the shaft (23) of the reversing frame body (20) will follow the fixed tube (14). The axis (Y1) gradually settles until the relatively low point shown in Figure 25d (less than one centimeter below the aforementioned relative high point). In this state, the wedge-shaped convex portion (213) on the top end surface of the cylindrical portion (211) of the reverse frame body (20) has been separated downward from the wedge-shaped concave portion (141) of the bottom end surface of the fixed pipe (14), so that the reverse frame body (20) It is rotatable relative to the main frame body (10) according to the aforementioned axis (Y1). When the reversing frame body (20) is rotated about the shaft (23), the opposite two rollers (72) supporting the torsion bar (71) will be centered on the shaft (23) on the support plate (73). Rolling along a circular path maintains the height of the torsion bar (71) relative to the fixed tube (14).

As shown in Figures 20 and 21, the pipe wall of the fixed pipe (14) is locked with a stop bolt (16) whose tail end projects in the pipe of the fixed pipe (14); on the other hand, the shaft ( 23) fixing a reverse limiting member (26) as shown in Fig. 24 at the corresponding position, the reverse limiting member (26) having a relative two locking surface that can be engaged with the rear end of the stopping bolt (16) (261), the angles of the aforementioned two locking faces (261) with the stopper bolts (16) are appropriately preset so that the rotatable range of the shaft (23) with respect to the fixed pipe (14) is limited to 180 degrees. When any of the locking faces (261) of the reverse stopper (26) is blocked by the stopper bolts (16), the two wedge-shaped projections (213) of the reverse frame body (20) are respectively fixed and fixed. The two wedge-shaped recesses (141) of the tube (14), meanwhile, the axis of the shaft tube portion (212) of the reversing frame body (20) (ie, the aforementioned second axis (X2)) corresponds to the left and right axial directions, and the displacement frame The axis of the aforementioned crankshaft (43) that is parallel to the second axis (X2) on the body (30) (i.e., the aforementioned first axis (X1)) is also the same.

Pull the aforementioned control knob (75) to utilize the eccentric portion of the torsion bar (71) (711) When the shaft (23) is pushed up, the design of the wedge-shaped convex portion (213) and the wedge-shaped concave portion (141) can automatically correct the inverted frame body (20) within a certain angular deviation. The angle is preset, and it will not be deflected after the lock. If the reversing frame body (20) has not been rotated until the wedge-shaped projections (213) substantially mate with the wedge-shaped recesses (141), the user cannot smoothly tighten the control knob (75) because the wedge-shaped projections (213) will immediately click. The bottom surface of the fixed pipe (14) is blocked, and the shaft (23) is prevented from pushing the eccentric portion (711) of the torsion bar (71) upward. The wedge-shaped convex portion (213) and the wedge-shaped concave portion (141) in the present embodiment respectively have corresponding radial ribs and concave grooves, but other shapes of the wedge-shaped convex portions and the wedge-shaped concave portions can exert similar effects.

In addition, the control twister (75) and the torsion bar (71) which together form a U-shape can produce the labor-saving effect of the "second type of lever", that is, the outer end of the control twister (71) is rotated to the torsion bar ( 71) The radial distance of the aforementioned main axis (corresponding to the urging arm) is several times the radial distance from the outer peripheral surface of the eccentric portion (711) (the portion for urging the shaft (23)) to the aforementioned main axis ( Corresponding to the anti-arm), the user can move the reversing frame body (20) together with the displacement frame body (30) along the fixed tube (14) without much effort to turn the control knob (75). Lati.

Further, as seen in detail, as shown in Fig. 25a, when the reversing frame body (20) is in the aforementioned lock state with respect to the main frame body (10), the outer peripheral surface of the eccentric portion (711) of the torsion bar (71) is shown. The portion farthest from the aforementioned main axis does not have a tip end direction corresponding to the axis of the shaft (23), but has a difference of about 15 degrees from the aforementioned axis. In the process of twisting the torsion bar (71) from the angle shown in Fig. 25a (locking angle) according to the clockwise direction in the figure to the angle (untwisting angle) shown in Fig. 25d, the longest part of the eccentric portion (711) The diameter (712) will be first from the shaft (23) shaft One side of the wire is twisted to correspond to the aforementioned axis (as shown in Figure 25b) and continues to the other side of the aforementioned axis. Because the shaft (23) can no longer rise relative to the fixed tube (14) in the locked state shown in Fig. 25a, the process of the 25th figure is passed through the process of Fig. 25b, and the torsion bar (71) is on the main axis. The two rollers (72) press the elastic support member (74) downward to make it slightly elastically contracted, that is, the height of the torsion bar (71) relative to the fixed tube (14) is slightly lowered to make the eccentric portion (711). The thick side of the shaft can pass over the top edge of the transverse hole (231) of the shaft (23). Similarly, in the process of twisting the torsion bar (71) from the untwisting angle shown in Fig. 25d to the locking angle shown in Fig. 25a in the counterclockwise direction in the figure, when twisting to the angle as shown in Fig. 25c At this time, although the portion of the outer peripheral surface of the eccentric portion (711) farthest from the main axis has not yet reached the top edge of the horizontal hole (231) of the shaft (23) (approximately 15 degrees difference), the shaft (23) has been pushed. Top to the top dead center relative to the fixed tube (14), at this time, the user must apply more force (overcoming the elastic force of the elastic support member (74)) to wrap the thick side of the eccentric portion (711) around the shaft (23). The other side of the axis. Thereby, under the action of insufficient external force, the torsion bar (71) does not deviate from the angle shown in Fig. 25a, in other words, the reversing frame body (20) can be stabilized in the locked state without accidental loosening.

In other implementation options, the aforementioned elastic support (disc spring) (74) and annular support plate (73) may be integrated into a single member, such as a cylindrical rubber block of suitable toughness.

As described above, when the hand exercise apparatus of the present embodiment assumes the operation type as shown in FIGS. 1 to 4, the user operates the aforementioned two cranks (41) with both hands along the corresponding clock in FIG. The direction of motion S of the direction is rotated to perform a hand motion with motion resistance. If the user wants to exercise To move the opposite hand, firstly loosen the aforementioned reverse locking device between the reversing frame body (20) and the main frame body (10) through the aforementioned control twisting handle (75), and then the reversing frame body (20) And the displacement frame body (30) is rotated by 180 degrees to the second angle according to the first angle shown in Figs. 3 and 4, according to the axis (Y1) of the fixed pipe (14), and then the control knob (75) is tightened. The reversing frame body (20) and the displacement frame body (30) which have been reversed before and after are re-fixed, so that the hand sports equipment exhibits an operation type as shown in Figs. Wherein, because the motion unit (40) (including the aforementioned crankshaft (41), one-way bearing (44)) has also been reversed back and forth with the displacement frame body (30), the user must now operate the crank (41). In Fig. 27, the movement direction S' corresponding to the counterclockwise direction is rotated to perform the hand movement with the motion resistance. Of course, after the reversal, the displacement frame body (30) attached to the left side of the reversing frame body (20) can still be deflected and positioned forward and backward with respect to the reversing frame body (20) according to the second axis (X2). Adjust the position of the motion unit (40) relative to the user. In this way, the user's hand movement mode has more choices, and the training effect can be more balanced and complete.
