SWINGABLE EXERCISE BIKE

Abstract

A swingable exercise bike includes a base having a first pivot portion for a bike body to be pivotally connected to the first pivot portion so that the bike body can swing left and right relative to the base. Left and right sides of the first pivot portion are provided with first connecting rods. The first connecting rods each have one end pivoted to the base and another end extending in a height direction and pivoted to a second connecting rod. The second connecting rod is further pivoted to the bike body. When the bike body swings left and right, the first and second connecting rods are pivoted. The two second connecting rods are connected with a cushion device disposed in a horizontal direction, which can generate a damping effect when the two second connecting rods are pivoted by the bike body, thereby cushioning the swing of the bike body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0015] Referring to FIG. 1 and FIG. 2, the present invention discloses a swingable exercise bike, comprising a bike body 11 and a base 1. The bike body 11 is a flywheel structure of any type in the prior art. The bike body 11 comprises a frame, a seat, an armrest, a rotating wheel, a pedal, a resistance wheel (not shown), and so on. The front and rear ends of the base 1 are provided with first pivot portions 12, respectively. The bike body 11 is pivotally connected to the first pivot portions 12, so that the bike body 11 is able to swing left and right relative to the base 1.

[0016] The front and rear ends of the base 1 are provided with supporting mechanisms 2 corresponding to the first pivot portions 12, respectively. As shown in FIG. 2, each supporting mechanism 2 includes two first connecting rods 21A, 21B located at left and right sides of the first pivot portion 12. The base 1 is provided with second pivot portions 13A, 13B at the left and right sides of the first pivot portion 12. The first connecting rods 21A, 21B each have one end pivotally connected to the second pivot portion 13A, 13B and another end extending in the height direction and pivotally connected to a second connecting rod 22A, 22B. Another end of the second connecting rod 22A, 22B is pivotally connected to the bike body 11. The pivotal positions at which the two second connecting rods 22A, 22B are connected to the bike body 11 are at the same height. In this embodiment, the length of the second connecting rod 22A, 22B is less than the distance between the first pivot portion 12 and the second pivot portion 13A, 13B. Thereby, the first connecting rod 21A, 21B is set to be inclined toward the first pivot portion 12 when the bike body 11 is not swung. In detail, the first connecting rod 21A located at the left side of the first pivot portion 12 is inclined toward the right side, and the first connecting rod 21B located at the right side of the first pivot portion 12 is inclined toward the left side. With the above structure, when the bike body 11 swings left and right relative to the base 1, the second connecting rods 22A, 22B are driven to link the first connecting rods 21A, 21B to generate a pivot.

[0017] Furthermore, the supporting mechanism 2 is provided with a cushion device 3. The cushion device 3 includes a damper 31 and two supports 32A, 32B. The two supports 32A, 32B are located at the left and right sides of the first pivot portion 12, respectively. The bottom ends of the two supports 32A, 32B are fixed to the second connecting rods 22A, 22B, respectively. The top ends of the two supports 32A, 32B extend upwardly. Two ends of the damper 31 are pivotally connected to the top ends of the two supports 32A, 32B, respectively. The damper 31 is disposed in the horizontal direction and is a device that can change in length, thereby absorbing the applied force and generating a cushioning effect. When the bike body 11 swings left and right relative to the base 1, the second connecting rods 22A, 22B are pivoted by the bike body 11 to drive the two supports 32A, 32B to change the distance between the two supports 32A, 32B, thereby compressing or extending the damper 31 to provide a cushioning effect.

[0018] With the above configuration, when the user swings the bike body 11 left, as shown in FIG. 3, the bike body 11 pushes and pulls the second connecting rods 22A, 22B at the two sides thereof, so that the two supports 32A, 32B are linked to compress or extend the damper 31. Accordingly, the action of swinging the bike body 11 to the left side is buffered, and the swing can be performed more stably to prevent the user from falling and being injured. Since the bike body 11 swings to the left side to pivot the second connecting rods 22A, 22B, the first connecting rods 21A, 21B are also pivoted. The first connecting rod 21A located at the left side is linked to pivot left, but does not swing beyond the left of its axis, thereby making the swing of the bike body 11 more stable and being supported.

[0019] On the other hand, when the user swings the bike body 11 right, as shown in FIG. 4, the bike body 11 pushes and pulls the second connecting rods 22A, 22B at the two sides thereof, so that the two supports 32A, 32B are linked to compress or extend the damper 31. Accordingly, the action of swinging the bike body 11 to the right side is buffered, and the swing can be performed more stably to prevent the user from falling and being injured. Since the bike body 11 swings to the right side to pivot the second connecting rods 22A, 22B, the first connecting rods 21A, 21B are also pivoted. The first connecting rod 21A located at the right side is linked to pivot right, but does not swing beyond the right of its axis, thereby making the swing of the bike body 11 more stable and being supported.

[0020] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
