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.

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to exercise apparatuses, and more particularly to a spinning bike.

2. Description of Related Art

Spinning bikes are exercise apparatuses for providing exercise that simulates bicycle riding. A spinning bike stands still on a fixed site by its support for a user to pedal the pedals and take training and exercise like riding a bicycle. Since the support is fixedly installed, the whole apparatus remains still except for the operatable pedals. The existing apparatus thus fails to provide realistic cycling experience and renders the training and exercise disadvantageously monotonous.

As an improvement, swingable spinning bikes have been developed. For example, Taiwan Utility Model Patent No. M471910 discloses a device having a bike body pivotally connected to a base, so that a user can pedal and swing his/her body and make the bike body pivotally swing to the left and the right with respect to the base like he/she is riding a real bicycle. This provides realistic cycling experience and adds the training and exercise with some interest.

However, there have not been any devices combining the functions of swingable and non-swingable spinning bikes. A gym owner may have to furnish his/her gym with both types of spinning bikes to address the training needs of his/her customers, and this unavoidably raises his/her operational costs.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a switchably swingable spinning bike, which has a switching device that switches swingability of the spinning bike, so as to make the spinning bike more applicable.

For achieving the foregoing objective, the present invention provides a switchably swingable spinning bike, which comprises:

a bike body and a base, the base having a pivot portion;

a swinging device, comprising a swinging seat fixed to the bike body and two buffers fixed to two ends of the swinging seat, wherein the swinging seat is pivotally connected to the pivot portion of the base, and the two buffers flank the pivot portion, so that the swinging seat when pivotally swinging with respect to the base alternately presses against the buffers; and

a switching device, being installed on the swinging seat and comprising two undeformable propping members that flank the pivot portion, wherein each said propping member is controllable to slide 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 into a non-swingable state.

In one embodiment, the switching device further comprises a rail member fixed to the swinging seat and extending toward two ends of the swinging seat, on which rail member two mounts are provided positionally corresponding to two sides of the pivot portion, respectively, so that each said mount positionally corresponds to one said propping member, and each said mount has a rail groove for the corresponding propping member to slidably engage with the mount and slide thereon with respect to the swinging seat.

Furthermore, each said mount extends laterally and has a retaining plate atop, the retaining plate being flanked by two upright first lateral plates, each said first lateral plate being provided with one said rail groove; each said propping member having a top plate configured to be placed on the corresponding mount, and having two second lateral plates flanking the two first lateral plates of the corresponding mount, each said second lateral plate slidably engaging with the corresponding rail groove with a positioning pin, so that the propping members are allowed to be controlled to slide along the rail grooves with respect to the mounts until the top plates leave the retaining plates and the propping members fall down and prop between the swinging seat and the base, thereby limiting the swinging seat's pivotal swing with respect to the base. In addition, each said mount is slidably mounted on the rail member so as to be slidable with respect to the rail member.

In one embodiment, each said buffer is a cushion or a spring.

DETAILED DESCRIPTION OF THE INVENTION

Referring toFIG. 1andFIG. 2, according to the present invention, a switchably swingable spinning bike comprises a bike body11and a base1. The bike body11is 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 base1has its front and rear ends each provided with a pivot portion12.

The bike body11is connected to the base1at each of its front and rear ends through a swinging device2. The swinging device2has a swinging seat21and two buffers22. The swinging seat21is fixedly connected to the bike body11at its one side, and is pivotally connected to a pivot portion12of the base1at the center of its opposite side, so that the bike body11is allowed to pivotally swing between the right and the left against the pivot portion12with respect to the base1. The two buffers22are screwed to the swinging seat21through screws221and flank the pivot portion12, so that the bike body11when pivotally swinging between the right and the left alternately presses against the buffers22. The buffers when pressed deform to provide resilient buffering, so as to damp the pivotal swing of the bike body11. In the present embodiment, the buffers22may be cushions or springs.

Each of the swinging devices2further has a switching device3. The switching device3comprises a rail member31. The rail member31is fixed to the swinging seat21through a stationary seat311and the stationary seat311extends a rail shaft312across two sides of the swinging seat21. The rail shaft312is mounted with two mounts32corresponding to two sides of the pivot portion12, respectively. In the present embodiment, each of the mounts32is slidably mounted around the rail shaft312, so is able to slide with respect to the rail member31.

A propping member33is attached to each of the mounts32. In the present embodiment, the mount32extending laterally and has a retaining plate321atop. The retaining plate321is flanked by two upright first lateral plates322. Each of the first lateral plates322has a laterally extending, slot-like rail groove323. Each of the propping members33is made of an undeformable rigid material, and has a top plate331configured to be placed on the corresponding mount32and two second lateral plates332flanking the two first lateral plates322of the corresponding mount32. The two second lateral plates332each have a positioning pin333. The positioning pins333are slidably received in the rail groove323of the mount32, so that the propping member33slidably engages with the mount32. Thereby, the propping member33can be controlled to slide along the rail grooves323by means of the positioning pins333, so as to slide and displace with respect to the mount32(in turn with respect to the swinging seat21).

With the aforementioned configuration, the present invention provides the switching device3that switches the bike body11between swingable and non-swingable states. Particularly, as shown inFIG. 3, when the propping member33is retracted and placed on the mount32, the top plate331is stacked on the retaining plate321of the mount32, so that the propping member33is positioned and not in contact with the base1. At this time, the swinging seat21is not limited and pivotable with respect to the base1, thereby allowing a user to operate and control the bike body11to pivotally swing to the left and the right. When the bike body11pivotally swings, the buffers22alternately receive force and deform accordingly as shown inFIG. 4, thereby providing resilience that returns them to the original shape as buffering means.

For switching the bike body11into the non-swingable state, as shown inFIG. 5, a user pulls the propping members33to slide their positioning pins333in the rail grooves323of the mounts32, so as to laterally pull the propping members33out of the swinging seats21. As a result, the top plate331each of the propping members33leaves the retaining plate321of the corresponding mount32, and the propping members33fall down by gravity due to loss of support, as shown inFIG. 6. In the present embodiment, the mounts32may be alternatively pulled outside the swinging seat21until the propping members33completely become outside the swinging seat21, so as to facilitate the propping members33pivoting and falling down. In this state, each of the propping members33has its two ends propping against the swinging seat21and the base1, respectively. Since the propping members33do not deform even when receiving pressing force, they limit the swinging seat21from swing, and in turn prevent the bike body11from swing with respect to the base1.

It is thus clear from the above that the present invention is advantageous for it provides a single bike body11having swingable and non-swingable states that can be easily switched using the switching device3, thereby maximizing functionality of the present invention. In addition, the present invention can satisfy various users with different preferences, thus being economically beneficial.
