Switchably swingable spinning bike

Abstract

A switchably swingable spinning bike includes a bike body and a base. The base has a pivot portion and is pivotally connected to a swinging seat of a swinging device. The swinging seat has two buffers flanking the pivot portion. The swinging seat has a switching device that includes two undeformable propping members that flank the pivot portion. Each of the propping members is slidable with respect to the swinging seat until it props between the swinging seat and the base, thereby limiting the swinging seat's pivotal swing with respect to the base, and in turn switching the bike body from a swingable state to a non-swingable state.

DETAILED DESCRIPTION OF THE INVENTION

(6) Referring to FIG. 1 and FIG. 2, according to the present invention, a switchably swingable spinning bike comprises a bike body 11 and a base 1. The bike body 11 is of any common structure of spinning bikes known in the art, and primarily comprises a frame, a saddle, a handle bar, a rotatory wheel, pedals, and a damper wheel. The base 1 has its front and rear ends each provided with a pivot portion 12.

(7) The bike body 11 is connected to the base 1 at each of its front and rear ends through a swinging device 2. The swinging device 2 has a swinging seat 21 and two buffers 22. The swinging seat 21 is fixedly connected to the bike body 11 at its one side, and is pivotally connected to a pivot portion 12 of the base 1 at the center of its opposite side, so that the bike body 11 is allowed to pivotally swing between the right and the left against the pivot portion 12 with respect to the base 1. The two buffers 22 are screwed to the swinging seat 21 through screws 221 and flank the pivot portion 12, so that the bike body 11 when pivotally swinging between the right and the left alternately presses against the buffers 22. The buffers when pressed deform to provide resilient buffering, so as to damp the pivotal swing of the bike body 11. In the present embodiment, the buffers 22 may be cushions or springs.

(8) Each of the swinging devices 2 further has a switching device 3. The switching device 3 comprises a rail member 31. The rail member 31 is fixed to the swinging seat 21 through a stationary seat 311 and the stationary seat 311 extends a rail shaft 312 across two sides of the swinging seat 21. The rail shaft 312 is mounted with two mounts 32 corresponding to two sides of the pivot portion 12, respectively. In the present embodiment, each of the mounts 32 is slidably mounted around the rail shaft 312, so is able to slide with respect to the rail member 31.

(9) A propping member 33 is attached to each of the mounts 32. In the present embodiment, the mount 32 extending laterally and has a retaining plate 321 atop. The retaining plate 321 is flanked by two upright first lateral plates 322. Each of the first lateral plates 322 has a laterally extending, slot-like rail groove 323. Each of the propping members 33 is made of an undeformable rigid material, and has a top plate 331 configured to be placed on the corresponding mount 32 and two second lateral plates 332 flanking the two first lateral plates 322 of the corresponding mount 32. The two second lateral plates 332 each have a positioning pin 333. The positioning pins 333 are slidably received in the rail groove 323 of the mount 32, so that the propping member 33 slidably engages with the mount 32. Thereby, the propping member 33 can be controlled to slide along the rail grooves 323 by means of the positioning pins 333, so as to slide and displace with respect to the mount 32 (in turn with respect to the swinging seat 21).

(10) With the aforementioned configuration, the present invention provides the switching device 3 that switches the bike body 11 between swingable and non-swingable states. Particularly, as shown in FIG. 3, when the propping member 33 is retracted and placed on the mount 32, the top plate 331 is stacked on the retaining plate 321 of the mount 32, so that the propping member 33 is positioned and not in contact with the base 1. At this time, the swinging seat 21 is not limited and pivotable with respect to the base 1, thereby allowing a user to operate and control the bike body 11 to pivotally swing to the left and the right. When the bike body 11 pivotally swings, the buffers 22 alternately receive force and deform accordingly as shown in FIG. 4, thereby providing resilience that returns them to the original shape as buffering means.

(11) For switching the bike body 11 into the non-swingable state, as shown in FIG. 5, a user pulls the propping members 33 to slide their positioning pins 333 in the rail grooves 323 of the mounts 32, so as to laterally pull the propping members 33 out of the swinging seats 21. As a result, the top plate 331 each of the propping members 33 leaves the retaining plate 321 of the corresponding mount 32, and the propping members 33 fall down by gravity due to loss of support, as shown in FIG. 6. In the present embodiment, the mounts 32 may be alternatively pulled outside the swinging seat 21 until the propping members 33 completely become outside the swinging seat 21, so as to facilitate the propping members 33 pivoting and falling down. In this state, each of the propping members 33 has its two ends propping against the swinging seat 21 and the base 1, respectively. Since the propping members 33 do not deform even when receiving pressing force, they limit the swinging seat 21 from swing, and in turn prevent the bike body 11 from swing with respect to the base 1.

(12) It is thus clear from the above that the present invention is advantageous for it provides a single bike body 11 having swingable and non-swingable states that can be easily switched using the switching device 3, thereby maximizing functionality of the present invention. In addition, the present invention can satisfy various users with different preferences, thus being economically beneficial.
