Detailed Description

As can be seen from FIG. 1, the first embodiment of the exerciser of the present invention is broken down into: a vehicle body 10, a seat body 40, two elastic ropes 56 and some components. Two hook bodies 57 are tied to the two ends of the elastic cord 56. The zero (component) comprises: a guard 22, three

rods

23, 26 and a shaft 27, one of the rods 23 incorporating a ring 24 and the other rods 26 each being connected to an outer ring 26.

The vehicle body 10 includes: a solid part, a rotating part, a front wheel 20 and a rear wheel 21. The solid part is generally referred to as a connecting pipe 11 for connecting a head pipe 12 and a rear fork 15, a secondary pipe 16 is fixed at the position where the connecting pipe 11 is combined with the rear fork 15, and a quick release 17 is arranged at the mouth of the secondary pipe 16. The rotating part means that a front fork 14 is connected to a handle bar 13 through a head pipe 12, and the handle bar 13 operates the front fork 14 to rotate in the same direction. The front wheel 20 is pivotally connected to one end of the front fork 14, and the rear wheel 21 is pivotally connected to one end of the rear fork 15. In particular, the vehicle body 10 is not equipped with a transmission device, and the rear wheel 21 cannot be driven to rotate on the vehicle body 10.

The holder body 40 comprises: two fixed seats 30, a first plate 41, a second plate 45, two coupling rods 50 and a set of suckers 60. When the sets of fasteners 31 are removed, the holders 30 are moved away from the vertically interleaved first and

second plates

41, 45, allowing the first plate 41 to move away from the second plate 45. Two spacers 43 are coupled to both ends of the first plate 41, and the spacers 43 have the same thickness as the second plate 45. The number of the suction cups 60 is five, and the suction cups are respectively arranged on the bottom surfaces of the two ends of the second plate 45, the bottom surface of the staggered part of the second plate 45 and the first plate 41 and the bottom surface of the cushion block 43.

In addition, a coupling hole 51 is formed at each end of each coupling rod 50, and a protrusion 53 and a pin hole 54 are formed between the two coupling holes 51. When the connecting rod 50 is inserted into one of the holes 46 of the second plate 45, the pin hole 54 is exposed to the other side of the second plate 45. When one pin 55 is inserted into the pin hole 54, the protrusion 53 engages the pin 55 to block both sides of the second plate 45, so that the coupling link 50 is coupled to the end of the second plate 45. At this time, two snap rings 52 are disposed at the coupling holes 51 at both ends of the coupling bar 50, and each snap ring 52 is exposed to the outside of the second plate 45.

Referring next to fig. 2, the assembly of the exerciser will be described in detail. The rod 23 is tightened by the quick release 17 through the sub-pipe 16, so that the rod 23 is combined with the vehicle body 10. The guard 22 is depicted as an object in phantom, and can be incorporated into the end of the rod 23 extending out of the secondary tube 16. When the ring 24 is interposed between the two outer rings 25, the shaft 27 passes through the side-by-

side rings

24 and 25, so that the three

rods

23, 26 are connected together so as to be able to rotate relative to each other about the shaft 27. The two rods 26 are inserted into the fixing seats 30, respectively, and the fixing seats 30 are locked on the top surface of the first plate 41 by the fastening members 31, so that the outer ring 25 is mounted on the housing 40. The seat 40 is connected to the vehicle body 10, and the vehicle body 10 swings back and forth about the shaft 27 relative to the seat 40 so that the front wheels 20 and the rear wheels 21 contact the seat 40, respectively.

When the quick release 17 releases the tightening relationship, the sub-tube 16 and the rod 23 move relative to each other, and the position or height of the vehicle body 10 on the seat 40 can be adjusted. The quick release 17 presses the nozzle retaining rod 23 of the sub-pipe 16 to restore the tightening relationship again.

When the hook 57 hooks the buckle 52, the two elastic cords 56 respectively tie the front wheel 20 and the rear wheel 21 and apply two forces in opposite directions to the vehicle body 10. The two forces are substantially equal to each other, and the front and

rear wheels

20, 21 are driven away from the second plate 45, so that the vehicle body 10 maintains a balanced state with respect to the seat body 40. The body 40 can be placed on a support surface 62 (see fig. 4), such as the floor.

In fig. 3, an assembled aspect of the holder body 40 is further described. Wherein the fastener 31 is a stud which passes through the flange of the mounting block 30, through a hole 42 in the first plate 41 and into a blind hole 49 in the second plate 45, locking a nut 33 into tight engagement.

At this point, the rod 26 continues through a central hole 32 of the holder 30 into a through hole 44 of the first plate 41 and a groove 47 of the second plate 45, allowing the outer ring 25 to be mounted in the holder body 40. In addition, a convex post 61 of the suction cup 60 is combined with a concave portion 48 of the second plate 45, so that the sum of the weight of the exerciser is transmitted to the suction cup 60, the suction cup 60 tightly sucks the supporting surface 62 (see fig. 4), and the exerciser is prevented from being arbitrarily displaced.

During the initial period of exercise, the body 10 is balanced as shown in FIG. 4. Imagine a user (not shown) standing on the vehicle body 10, grasping the handlebar 13 with both hands and stepping on the rear fork 15.

When starting the exercise, the user operates the exerciser to swing forward, assuming that the user changes the center of gravity of the vehicle body 10 as shown in fig. 5. In response to the tilted vehicle body 10, the front wheel 20 contacts the second plate 45, and the tension of the elastic cord 56 is maintained in a relaxed state. At this point, the rear wheel 21 is moved away from the second plate 45 or support surface 62, causing the tension in the bungee cord 56 to remain taut.

In fig. 6, the user pulls up the handle bar 13, lifts the front wheel 20 by the front fork 14, and moves the front wheel away from the second plate 45 or the support surface 62, thereby maintaining the tension of the elastic cord 56 in a taut state. The vehicle body 10 shifts the position of the center of gravity and the user operates the exerciser to swing back to an angle. At the same time, the rear wheel 21 contacts the second plate 45, allowing the tension of the bungee cord 56 to remain relaxed.

In brief, the exerciser of this embodiment is placed in a limited space, and the two elastic cords 56 provide pulling force in turn, so as to help the user operate the body 10 to swing back and forth relative to the seat 40, so that the front wheel 20 and the rear wheel 21 land on the ground (i.e. contact the seat 40), and simulate the movement of a soil slope or a pump channel.

During the exercise, the user stands backwards or crouches down and leans forwards to actively change the posture of the exercise. Under the operation of the user, the body 10 swings about the shaft 27 relative to the body 40 to passively change the center of gravity of the exerciser. At this point, the guard 22 prevents the body from hitting the rod 23, and protects the body without interfering with the training of the user for extreme exercises.

FIG. 7 is a second embodiment of the exerciser, constructed substantially the same as the first embodiment, with the difference that: one more buffer 63. The cushion member 63 is disposed on the second plate 45, and absorbs the force of the front wheel 20 contacting the second plate 45, and reduces the impact force fed back to the hands by the handle 13.

FIG. 8 is a third embodiment of the exerciser, constructed substantially the same as the first embodiment, with the difference that: the ring 24 is inserted between two lugs 65, and the shaft 27 passes through the side-by-side ring 24 and the lugs 65 to form a pivot structure.

Of course, the lugs 65 stand on a support 64, and the support 64 passes through the fixing seat, the first plate and the second plate, so that the lugs 65 are installed on the seat body.

FIG. 9 is a fourth embodiment of the exerciser, constructed substantially the same as the first embodiment, with the difference that: the shaft 27 passes through a first leaf 71 and a second leaf 72, which together form a hinge 70.

In addition, an open slot 23a of the lever 23 receives the first blade 71, and the other set of fasteners 23b lock the lever 23 to the first blade 71. Each of the two rods 26a has an open slot 26c for receiving the second blade 72 and the other fastener 26b locks the second blade 72 to the rod 26 a. The rod 26a is inserted into the central hole 32 of the fixing base 30, and the fixing base 30 is fixed on the seat body 40, so that the hinge 70 is combined with the two fixing bases 30.
