The shaft member (61) is slightly displaceable relative to the first frame body (10) along the direction of the second insertion hole (14) penetrating the rear side wall (12) (that is, the aforementioned locking direction (D2)), in other words, the shaft The core member (61) may be slightly displaced between a position closer to the front side wall (11) (hereinafter referred to as a second pressing position) and a position farther from the front side wall (11) (hereinafter referred to as a second relaxed position) . In this example, when the semi-cylindrical surface (63) of the axial core member (61) simultaneously abuts the upper and lower edges of the second insertion hole (14), the axial core member (61) can no longer be displaced forward. That is, it is located in the aforementioned second pressing position.

Referring to FIG. 5, the main member (51) has a rectangular parallelepiped block body (52), a curved handle (53) extending rearward from the bottom of the block body (52), and a connecting bend. A transverse plate-shaped handle (54) at the rear end of the shank (53). The main part (51) is entirely made of cast iron except that the handle (54) is partially covered with rubber. The block body (52) itself has a receiving groove (55) which is recessed upward from the bottom surface, a through hole (56) which is forwardly passed from the rear side surface to the receiving groove (55), and a rearward through hole from the front side. A groove (55) and a hexagonal perforation (57) opposite the through hole (56). The main member (51) is located behind the shaft member (61), and the through hole (56) of the main member (51) is coaxial with the blind hole (64) of the shaft member (61). Referring to Figures 9 and 10, the hex nut (67) is embedded in the hexagonal through hole (57) of the main member (51). The hex nut (67) cannot rotate relative to the main member (51) but can follow Axial displacement. The aforementioned two elastic washers (66) are coaxially overlapped and housed in the pockets (55) of the main member (51), and the center hole pair of the elastic washers (66) is fitted through the through holes (56). The bolt rod (68) is forwardly inserted from the rear end of the through hole (56) of the main member (51), and the shaft passes through the two elastic washers (66) and the hex nut (67), and the front end is abutted against the shaft member. (61) blind hole (64) hole bottom; external thread of the circumferential surface of the bolt rod (68) and the through hole (56) of the main member (51) and the blind hole (64) hole of the shaft member (61) The wall does not interfere, but is screwed into the internal thread of the hex nut (67).

The retaining washer (77) is pressed against the outer side of the connecting arm (70) to prevent the male shaft (58) from coming out of the pivot hole (74). The axis of the two convex shafts (58) is coaxial with the axis of the two pivot holes (74), defining a second axis (A2) (see FIGS. 8 and 9), the main member (51) and the connecting arm ( 70) The relative deflection can be made with the second axis (A2) as the axis. The second axis (A2) corresponds to the left and right axis (x The shaft) intersects perpendicularly to the axis of the through hole (56).

The two elastic washers (66) are clamped between the rear side wall of the pocket (55) of the main member (51) and the rear end surface of the hex nut (67), and have produced a predetermined degree of axial compression deformation, that is, accumulation. The elastic spring force extending in the axial direction causes the main member (51) and the shaft member (61) to have a relatively distant tendency along the axial direction of the bolt rod (68). The bolt rod (68) has a hexagonal hole (69) recessed from the rear end toward the front. If necessary, the assembler or the user can use an Allen key (not shown) to pass through the back end of the through hole (56). The bolt shank (68) is twisted to force the aforementioned hex nut (67) to advance or retreat relative to the bolt rod (68) in the axial direction, thereby adjusting the degree of pre-deformation of the elastic washer (66).

Based on the above-mentioned structure, a portion of the control assembly (50) corresponding to the axial center of the semi-cylindrical surface (63) of the axial core member (61) (ie, the first axis (A1)) forms an axial center portion, and oppositely, the control assembly A portion of the (50) corresponding to the axis of the convex shaft (58) of the main member (51) (i.e., the second axis (A2)) forms a deflecting portion, and the top surface of the block (52) of the main member (51) A pushing portion is formed, and the control unit (50) can be deflected by the axial center portion to displace the deflecting portion and the pushing portion to different positions (detailed later). At the same time, the control unit (50) has an elastic portion between the deflecting portion and the axial portion (in this example, the second elastic washer (66)), and the elastic portion makes the distance between the deflecting portion and the axial portion The maximum elastic length of the elastic portion may be changed between a maximum length and a minimum length (described later in detail), and the elastic portion of the elastic portion may be relatively distant from the axial portion. Further, a portion of the control unit (50) corresponding to the foremost end of the shaft member (61) forms a pressing portion, and the pressing portion is connectable to the axial portion at the second pressing position and the second relaxed position. The displacement between the left and right wedges (31) of the intermediate member (30) of the second side can be abutted as far as possible.

The first bracket set (4) of the preferred embodiment further has a latch assembly (80), which is disposed on the rear side of the top end of the first frame body (10), similar to the control assembly (50), by left and right. The two lever members (81), a latch member (84), a through pin (85), a connecting plate (86) and a magnet (87) are formed. Each of the lever members (81) has a longitudinally elongated plate having a pivot hole (82) between the top end and the bottom end and a long pin hole (83) at the bottom end, and the two lever members (81) The left and right two-axis rods (65) of the shaft member (61) pivotally sleeved on the control assembly (50) by the pivot holes (82), respectively, with respect to the axial center member with the aforementioned first axis (A1) as an axis (61) Deflection. The portion of the lever member (81) located in front of the pivot hole (82) coincides with the arc shape of the front end of the cylindrical body (62) of the shaft member (61), and is also embedded in the rear side wall of the first frame body (10). The second insertion hole (14) on the (12) can abut the corresponding position of the left and right wedge-shaped blocks (31) of the intermediate member (30) together with the foremost end of the cylindrical body (62) (refer to FIG. 9) . A web (86) is coupled between the top ends of the left and right lever members (81) such that The two lever members (81) are shaped like the same body and are deflected synchronously. The magnet (87) is fixed to the bottom of the connecting plate (86), and the bottom surface thereof forms a pushed portion of the locking assembly (80) opposite to the block of the main member (51) of the control assembly (50) (52). The top surface (ie, the aforementioned pushing portion) is in front of the top. The latch member (84) is received in the tube (16) on the rear side wall (12) of the first frame body (10), and the axial direction of the latch member (84) corresponds to the axial direction of the tube tube (16). That is, it corresponds to the aforementioned locking direction (D2). The latch member (84) can be moved forward and backward relative to the first frame body (10) along the locking direction (D2), and the front end of the latch member (84) forms a positioning portion of the latch assembly (80) through the first frame body. The perforations (15) in the rear side wall (12) of (10) extend into the inner space of the first frame (10). The through pin (85) extends through the latch member (84) in the left and right axial direction (x axis), and the left and right ends are respectively protruded from the outside of the tube (16) by the slot (17) of the peripheral wall of the tube (16), and The elongated pin holes (83) respectively project into the bottom ends of the left and right lever members (81), so that the latch members (84) and the lever members (81) are mutually driven. Another elastic member (in this case, a helical compression spring) (90) is accommodated inside the tube (16) and located behind the latch member (84), and the opposite ends of the elastic member (90) respectively abut the tube ( 16) and the latch member (84) such that the latch member (84) continues to be subjected to a forwardly pushing force, such that the lever member (81) has a tendency to deflect the bottom end forward and the top end to deflect rearward.

In general, the latch assembly (80) is displaceable between a latch position as shown in FIG. 10 and an unlocked position as shown in FIG. 13, when the latch assembly (80) is in the latch position. The latch member (84) is located at the foremost end of the movable range (note: at this time, the through pin (85) abuts against the front end of the slot (17) of the tube (16)), and the front end of the latch member (84) (ie, The positioning portion extends into the inner space of the first frame body (10) and is embedded in one of the positioning holes (25) on the second side of the second frame body (20); otherwise, when the locking component (80) is located In the aforementioned unlocked position, the latch member (84) is located at the rear end of the movable range (note: at this time, the through pin (85) abuts against the rear end of the slot (17) of the tube (16)), the latch member The front end of (84) retreats to the rear side wall (12) of the first frame body (10), without any positioning holes (25) embedded in the second frame body (20), even without touching the second frame body (20) The second side (23). The aforementioned force exerted by the elastic member (90) on the latch member (84) causes the latch assembly (80) to have a tendency to be displaced toward the aforementioned latch position.

As mentioned above, the control unit (50) can be deflected with its axial center portion (i.e., the portion corresponding to the first axis (A1)) as its axis, so that its deflection portion (i.e., corresponding to the aforementioned second axis ( The position of A2) is displaced to a different position. Specifically, as shown in FIGS. 10 to 13, the deflection unit can sequentially pass through a first position (the position shown in FIG. 10) with respect to the axial portion. The two positions (the position shown in FIG. 11) and the third position (the position shown in FIG. 12) are displaced to a fourth position (the position shown in FIG. 13), and the fourth position can be reversed from the third position and The second position is displaced to the aforementioned first position. Generally speaking, the deflecting portion can move along a circular arc-shaped reciprocating trajectory with respect to the axial center portion, The aforementioned first position and the aforementioned fourth position can be understood as opposite ends of the aforementioned reciprocating trajectory. In the preferred embodiment, the first position to the fourth position corresponds to the bottom up, but in other embodiments of the invention (not shown), it may be designed in the opposite direction or in other predetermined directions. When the control unit (50) performs the aforementioned deflection, the deflecting portion drives the connecting arms (70) on the left and right sides to be pivoted correspondingly with the front end thereof, because the deflecting portion (the position corresponds to the rear end of the connecting arm (70) The distance between the pivot hole (74) and the front end of the connecting arm (70) is constant, so when the angle of the deflecting portion with respect to the axial portion is changed, the distance between the deflecting portion and the axial portion is based on the elasticity of the elastic portion. Slightly elongated or shortened, that is, between the aforementioned maximum length and the aforementioned minimum length.

Referring to FIG. 10, when the control unit (50) is deflected so that the opposite portion of the deflecting portion is in the first position, the connecting portion of the deflecting portion and the front end of the connecting arm (70) (note: the neck portion (72) in the figure) The center is set to be the end point, the same below) is located below the axial portion, and the distance between the deflection portion and the axial portion is a specific length between the maximum length and the minimum length, and is clamped in the deflection portion. The aforementioned two elastic washers (66) between the shaft and the core portion exhibit a predetermined degree of compression deformation (but not yet reached the maximum deformation), and the recovery elastic force corresponds to the deflection portion being relatively distant from the axial portion, that is, along the axial direction thereof. Pushing the aforementioned main member (51) and pushing the aforementioned hex nut (67) forward, so that the aforementioned pressing member (40) positioned on the first side of the first frame body (10) is connected to the arm (70) Pulling back based on the aforementioned elastic force to abut the first pressing position, and the aforementioned axial core member (61) positioned at the second side of the first frame body (10) is based on the aforementioned elastic force by the aforementioned bolt rod (68) Pushing forward to abut against the aforementioned second pressing position.

As shown in FIG. 8 and FIG. 10, when the deflecting portion is in the first position, the shafts (65) on the left and right sides of the shaft member (61) of the control unit (50) are respectively abutted to the left, The top edge of the hollow hole (75) of the right second connecting arm (70) is such that the deflecting portion of the control assembly (50) cannot be displaced from the first position away from the second position (in this example, downward) . Of course, the displacement of the deflecting portion from the first position to the second position is not limited to the above manner. As can be seen from FIG. 8 and FIG. 10, only the control unit (50), the connecting arm (70), and the first frame are provided. The body (10), wherein the predetermined portions of the two are in conflict with each other, such that the control assembly (50) or the connecting arm (70) cannot be deflected downwardly from the position shown, the same purpose can be achieved.

Referring to FIG. 11, when the control unit (50) is deflected so that the opposite position of the deflecting portion is in the second position, the connecting line between the deflecting portion and the front end of the connecting arm (70) passes through the aforementioned axial portion (ie, three points are connected). a straight line), the distance between the deflecting portion and the axial portion is the minimum length, in other words, the two elastic washers (66) are compressed to the most flat, and the accumulated elastic force is maximum. At this time, the first side pressing member (40) and The axial members (61) of the second side are respectively located at the first pressing position and the second pressing position, for the same reason.

Referring to FIG. 12, when the control unit (50) is deflected such that the opposite position of the deflecting portion is in the third position, the connecting line between the deflecting portion and the front end of the connecting arm (70) is above the axial portion, and the deflecting portion is The distance from the core portion is greater than the aforementioned specific length in the state of Fig. 10, and the aforementioned two elastic washers (66) are completely stretched and not compressed (note: the elastic washer (66) and the rear of the pocket (55) Between the side walls, and/or between the elastic washer (66) and the rear end surface of the aforementioned hex nut (67), there may or may not be a gap), so that the main component (51) and the shaft member of the control assembly (50) (61) there is no elastic force pushed apart from each other, therefore, the pressing member (40) of the first side is not pulled back by the connecting arm (70) based on the aforementioned elastic force, and the axial member of the second side (61) ) is not pushed forward by the bolt rod (68) based on the aforementioned elastic force, so that the pressing member (40) can be loosened forward from the first pressing position to the aforementioned first relaxed position, and the shaft member (61) It is also possible to loosen backward from the aforementioned second pressing position to the aforementioned second relaxed position.

In Fig. 12, the top surface of the block (52) of the main member (51) of the control unit (50) (i.e., the aforementioned pushing portion) just contacts the magnet of the aforementioned latch assembly (80) located at the aforementioned latch position ( 87) the bottom surface (i.e., the aforementioned pushed portion), but Fig. 12 is mainly presented for the convenience of the reader to understand the continuous motion during operation (detailed detail), and is not the condition or result of "the aforementioned deflecting portion is in the aforementioned third position", the fact Above, for example, after the control assembly (50) is deflected upward by a predetermined angle from the position shown in FIG. 11, and before the pushing portion contacts the aforementioned pushed portion (for example, the position drawn by the imaginary line in FIG. 12), the elastic washer (66) It may have been fully extended so that the pressure member (40) and the shaft member (61) can be loosened from the respective pressing positions to the relaxed position. It means that, unlike the first position and the second position, the third position is not a specific point on the reciprocating trajectory of the deflection unit, but is preferably understood to be any point among the specific sections of the trajectory.

Referring to FIG. 13, when the control assembly (50) is deflected such that the aforementioned deflecting portion is opposite to the fourth position, the aforementioned pushing portion of the control assembly (50) abuts the aforementioned pushed portion of the latch assembly (80), and Push the latch assembly (80) against the aforementioned unlocked position. Of course, since the distance between the deflecting portion of the control assembly (50) and the axial portion in this state is larger than that shown in Fig. 12, between the main member (51) of the control assembly (50) and the axial member (61) There is no elastic force pushed away from each other, so the pressing member (40) and the shaft member (61) are not restricted to the first pressing position and the second pressing position.

Next, the method and work of using the first bracket set (4) of the preferred embodiment will be described. principle. When the first bracket group (4) is in the state shown in FIG. 10, the second frame body (20) is simultaneously locked in both the card insertion and the pressing manner, and is completely unable to move. In detail, the locking component (80) is located at the locking position, and the front end of the latching member (84) is embedded in one of the positioning holes of the second side of the second frame (20). (25), and the other portion of the latch member (84) is also inserted into the tube (16) on the second side of the first frame (10), in other words, the pin member (84) is along the aforementioned locking direction (D2) The card is interposed between the first frame body (10) and the second frame body (20) such that the second frame body (20) cannot be moved up and down along the aforementioned adjustment direction (D1) (perpendicular to the locking direction). Because the latch assembly (80) continues to be pushed by the aforementioned elastic member (90) to push the latching position, the latch assembly (80) does not disengage from the latch unless otherwise subjected to a reverse and sufficient external force. position.

On the other hand, the pressing member (40) of the first bracket group (4) is used for pressing the second frame body (20) from the first side to the second side, and the control assembly (50) The pressing portion (ie, the front end portion of the shaft member (61)) is for pressing the second frame body (20) from the second side to the first side. In the preferred embodiment, the pressing member (40) and the pressing portion respectively press the second frame (20) through the wedge block (31) of the intermediate member (30). As shown in FIG. 9, each wedge block (31) of the first side (the left side of FIG. 9) is respectively disposed on the first pressure receiving surface (22) of the pressing member (40) and the second frame body (20). Between the first pressing position and the inclined surface (33), the first pressure receiving surface (22) is pressed by the pressing member (40) to the first pressing position; and the second side (the right side of FIG. 9) is oppositely Each wedge block (31) is respectively disposed between the axial core member (61) and the second pressure receiving surface (24) of the second frame body (20), and is connected to the second pressing position with the shaft core member (61). Displacement and pressing the aforementioned second pressure receiving surface (24) with the aforementioned inclined surface (33). In the state shown in FIG. 10, the first side pressing member (40) and the second side axial member (61) are respectively located at the first pressing position and the second pressing position, respectively. The four wedge blocks (31) are pressed and fixed by the pressing member (40) and the shaft member (61) (and the aforementioned lever member (81)), and are respectively tightly packed in the first frame body (10). And the four corners between the second frame (20), so that the second frame (20) is further pressed and positioned, including difficulty in sliding in the aforementioned adjustment direction (D1), and perpendicular to the adjustment direction (D1) There is no loose space on the plane (ie, the plane formed by the aforementioned locking direction (D2) and the left and right axis (x-axis)). Based on the elastic action of the aforementioned two elastic washers (66), the control assembly (50) in the state of FIG. 10 has a tendency to deflect downward, but is positioned at the angle indicated by the downward deflection, and unless reversed and Sufficient external force, otherwise it will not deflect at the angle (upward) shown in Figure 11. At the same time, the pressing member (40) and the axial member (61) are also positioned at their respective pressing positions due to the aforementioned elastic force.

Please refer to FIG. 1 , by the above double locking of the first bracket group ( 4 ) Pressing), when the user of the aforementioned bicycle (1) rides on the aforementioned seat group (6), the first bracket group (4) can stably support the user's body weight or even the entire weight, so that the seat The group (6) is stabilized at the corresponding height and does not slide downward, and the second frame (20) does not sway and generate collision noise with respect to the first frame (10). In this locked state, unless the control assembly (50) is turned up by a sufficient amount of force above a predetermined angle, the locked state does not self-release or slack.

If the user wants to adjust the height of the seat set (6), the above double locking of the first bracket set (4) must be manually released, so that the second frame body (20) can be moved up and down along the adjustment direction (D1). Relock after reaching the appropriate height. Wherein, when unlocking, the user can hold the seat set (6) with one hand or hold the second frame (20), and use the other hand to hook the bottom of the handle (54) at the last end of the control assembly (50) and pull up. First, the control component (50) is first deflected from the angle shown in FIG. 10 through the angle shown in FIG. 11 to the angle shown in FIG. 12 (the imaginary line position is also possible), the pressure-locking is released, and the control component (50) is further activated. The angle shown in Fig. 12 is deflected to the angle shown in Fig. 13, and the snap-in locking is released. When relocking, the front is locked in the reverse direction and then locked in the reverse direction, and returns to the state shown in FIG.

In detail, when the user applies force to rotate the control assembly (50) upward from the angle shown in FIG. 10, at the beginning, its force must be able to further compress the two elastic washers (66) to make the aforementioned deflecting portion and the aforementioned The distance of the axial center is shortened, and when the angle shown in Fig. 11 is exceeded (i.e., the elastic washer (66) is pressed to the flattenest, the aforementioned distance is the smallest), the recovery elastic force of the elastic washer (66) becomes the control resist (50) upward. After the elastic washer (66) is fully extended, the elastic force between the deflecting portion and the axial portion disappears, and the pressing member (40) and the axial member (61) can be pressed by the respective pressing positions. Loosen to the relaxed position, and the wedge blocks (31) are not pressed against the second frame (20) by the opposite sides, that is, the resistive locking is first released. Then, when the user applies force to rotate the control assembly (50) upward from the angle shown in FIG. 12, the aforementioned pushing portion of the control assembly (50) (ie, the top surface of the block (52)) and the locking assembly (80) The aforementioned pushed portion (i.e., the bottom surface of the magnet (87)) is maintained in an abutting state, and is axially deflected by the aforementioned first axis (A1), wherein the aforementioned lever member (81) of the latch assembly (80) is obtained. Torque from the control assembly (50) (corresponding to the counterclockwise direction in the figure), so it is possible to temporarily resist the torsion (corresponding to the clockwise direction in the figure) from the aforementioned elastic member (90), so that the lever member (81) The top end is deflected forward, the bottom end is deflected backward, and the latch member (84) is retracted in the locking direction (D2) with the bottom end, so that the latch assembly (80) is displaced from the latch position shown in FIG. The unlocked position shown in 13 The snap-in lock is also released. When unlocking in the above manner, the user does not need to pull the control assembly (50) from the angle shown in FIG. 10 to the angle shown in FIG. 13 in one breath, and can be slightly stopped near the angle shown in FIG.

When the first bracket group (4) is in the state shown in FIG. 13, the user can apply a force to move the second frame body (20) up and down within a predetermined range along the adjustment direction (D1), thereby adjusting the top end thereof. Seat set (6) height. During the adjustment of the height, the user still needs to apply a force to hold the control assembly (50) to maintain the lock assembly (80) in the unlocked position, so that the second frame (20) is not interfered by the latch (84). It can smoothly move up and down. By raising or lowering the second frame (20) to the appropriate height, the user can relax the force of the control assembly (50) and cause the lock assembly (80) to lock based on the force of the elastic member (90). The position of the buckle is displaced, and the control assembly (50) is also deflected from the angle shown in Fig. 13 to the angle shown in Fig. 12. At this time, if one of the positioning holes (25) of the second frame (20) just coincides with the pin member (84), the latch member (84) is directly inserted into the positioning hole (25), otherwise, the front end of the latch member (84) temporarily abuts against the second side (23) of the second frame (20), The user then raises or lowers the second frame (20) slightly, and the latch member (84) is inserted into the nearest positioning hole (25) to return to the state shown in FIG.

In the state shown in Fig. 12, although the second frame body (20) is no longer able to move up and down, it may still be slightly loosened in all directions, so a second stage of pressure locking is required. That is, the user can press down on the handle (54) at the rear end of the control assembly (50) to deflect the control assembly (50) downward from the angle shown in FIG. 12, initially, to control the shaft member at the front end of the assembly (50). (61) first resisting the second pressing position, and the deflecting portion gradually approaches the axial center portion, and then the user's urging force must be capable of compressing the two elastic washers (66) to make the deflecting portion and the aforementioned The distance between the core portions is further shortened, and when the angle shown in Fig. 11 is exceeded (i.e., the elastic washer (66) is pressed to the flattenest, the aforementioned distance is the smallest), the recovery elastic force of the elastic washer (66) becomes the control assembly (50) Deflection, until the control assembly (50) is clamped to the angle shown in FIG. 10, the pressing member (40) and the axial member (61) are respectively located at the first pressing position and the second pressing position. , (through the wedge blocks (31)), the second frame body (20) is pressed against the opposite sides, so that the second frame body (20) is again double-locked and cannot be moved.

As mentioned above, the aforementioned bolts (68) of the torsion control assembly (50) by means of an Allen key (not shown) can adjust the degree of pre-deformation of the two elastic washers (66). In practice, this function can be adjusted. The elastic force of the elastic washer (66) in the state of Fig. 10 is to achieve a desired balance between the pressing tightness and the operability (referring to the degree of labor required by the user to apply force to compress the elastic washer (66)); With this adjustable structure, the dimensional accuracy of the relevant components is not too high, so that the components are produced Production and assembly are easier. In other embodiments of the invention, the amount of spring force of the resilient portion of the control assembly may not be adjustable.

In the state shown in Fig. 12, the top surface of the block (52) of the (cast iron) main member (51) of the control unit (50) and the bottom surface of the magnet (87) at the top end of the lock assembly (80) can be used by The magnetic force is attracted together, so that even if the user does not apply force to the control assembly (50) at this time, even if the hand leaves the handle (54), the control assembly (50) can maintain the angle shown in Fig. 12, not because It sinks down by its own weight (for example, it is deflected from the position shown by the solid line in the figure to the position shown by the imaginary line). Sometimes the user can't adjust the second frame (20) to the ideal height at one time, and may repeatedly cancel the embedded card lock (from Figure 12 to Figure 13), adjust the height, and re-embed the card lock (by the figure) 13 to Fig. 12), after the height is completely satisfied, the pressure lock is performed (from Fig. 12 to Fig. 10). With the above magnetic design, the deflection stroke when the card is locked can be shortened, which is advantageous for operation.

As can be seen from the above detailed description, the first bracket set (4) of the preferred embodiment can be used for the user to quickly unlock, move, and re-lock the second frame (20) relative to the first frame (10). Moreover, in the locked state, not only does it have no loose space, but also does not slip or loose when subjected to a large force. In addition, the user can lock and unlock in a single, continuous motion, which is relatively simple to operate.

Next, the similarities and differences between the second bracket set (5) and the first bracket set (4) of the second preferred embodiment of the present invention will be briefly described. Referring to FIG. 14, the second bracket set (5) of the preferred embodiment also has a first frame body (10') and a second frame body (20') constituting the telescopic rod structure, and is disposed on the first frame. a second intermediate member (30') at the top of the body (10'), a pressing member (40') disposed on the first side of the first frame (10') (on the right side in the figure), and disposed on the first frame a control component (50') of the second side (left side) of the body (10'), and left and right two connecting arms connected between the pressure member (40') and the control assembly (50') 70') (Note: only the right connecting arm is shown in the figure), wherein the control component (50') is also composed of a main part (51'), a shaft core (61'), and two elastic washers (66'). A hexagonal nut (67') and a bolt rod (68'). The shape and material of the members of the second bracket group (5) and the joint structure, the interlocking relationship between the members and the members are basically the same as the corresponding portions in the first bracket group (4) (Note: The second bracket set (5) shown in FIG. 14 corresponds to the state of the first bracket set (4) shown in FIG. 10, and the aforementioned adjustment directions of the two (5) (4) and the directions of the first and second sides The configuration profile is reversed before and after. The same part will not be described again. The main difference is that the second bracket group (5) does not have the aforementioned latch assembly (80) and the elastic member (helical compression spring) (90) possessed by the first bracket group (4), and the second bracket The first frame of the group (5) (10') The second side is not provided with the tube (16) for accommodating the latch member and the elastic member, and the second side of the second frame (20') is also not provided (for inserting the latch member) The aforementioned positioning hole (25).

In short, when the second bracket group (5) is in the locked state shown in FIG. 14, the second frame body (20') is only locked by the pressure, that is, the pressure applying member (40') and the aforementioned shaft center. The member (61') is clamped to the second frame (20') by the opposite sides (through the wedge block (31') of the aforementioned intermediate member (30'), instead of being double-locked (pressured as in the previous embodiment) The card is inserted, that is, there is no design of the positioning hole (25) of the second frame (20) with the latch member (84) of the first bracket set (4) using the latch assembly (80). The operation and principle of the above-mentioned pressure-locking and releasing of the second bracket group (5) are basically the same as those of the first bracket group (4), and will not be described again. Because the second bracket set (5) is used to support the grip set (7) on the aforementioned exercise bicycle (1) (see FIG. 1), that is, to support the hand pressure or upper body weight when the user moves. The load is relatively light, so there is no need for the first bracket set (4) that can support the user's whole body weight to have a card locking mechanism to ensure stability, in other words, in the preferred embodiment, the second bracket set ( The second frame (20') of 5) is locked based on the above-mentioned structure and principle, that is, the predetermined weight can be stably supported, and there is no loose space in the locked state.

In the following, some possible embodiments of the present invention are further described. For ease of understanding, the following examples are all based on the basic structure of the preferred embodiment and are partially modified without corresponding drawings. In the present invention, each side of the second frame may have only one continuous pressure receiving surface, and each pressure receiving surface may be a plane (similar to the first pressure receiving surface (22) or the second pressure receiving surface (24)). The wedge-shaped block is pressed against the inclined surface, and may also be a convex curved surface extending from the left side to the right side, and the left and right wedge-shaped blocks respectively press the left and right sides with the inclined surface thereof. In addition, the pressing member and/or the pressing portion in the present invention may directly (without passing through the intermediate member) directly press against the second frame body, for example, the pressing member itself is a wedge-shaped block, or two wedge-shaped blocks are symmetrically juxtaposed. The shape, when it is displaced to the pressing position, directly presses the second frame toward the second side with its inclined surface. Furthermore, the second frame body of the present invention may have a pressure receiving surface only on the first side edge, that is, when the pressure locking is performed, only the pressure member of the first side side presses the second frame body. Until the second frame is resisted by the second side of the first frame (for example, the front side wall (12), or the fixed wedge block); correspondingly, the axial portion of the control assembly can be directly pivoted a fixed position of the second side of the first frame is not displaced relative to the first frame in the locking direction. When the deflecting portion of the control assembly passes the third position beyond the second position to reach the first position, the same is also permeable. The connecting arm pulls the pressing member to the pressing position to press the second frame. There may be only one connecting arm in the present invention, and it is not limited to a pair. In the present invention, setting a control group The frame of the piece and the pressure member is called the first frame body, and the other frame body is called the second frame body. In practical application, the second frame body may be fixed, and the first frame body can be in the second frame body. The upper edge is displaced in the direction of adjustment.
