Chair capable of being firmly stacked
A chair capable of being firmly stacked comprises a seat; at least one supporting leg being connected to a bottom of the seat, the supporting leg including a resisting section and a wheel assembly; one end of the resisting section being connected to a bottom of the seat and another end of the resisting section being connected to the wheel assembly; the wheel assembly including a connecting block and a wheel pivoted to the connecting block; one inner side of the connecting block being formed with a resisting groove; the wheel being installed at an outer side of the supporting leg and being rotatable with respect to the connecting block; the resisting groove having a shape corresponding to a periphery of the resisting section so that the resisting groove can receive the resisting section of another chair.
The present invention relates to chairs, and particularly to a chair capable of being firmly stacked, wherein the stacking of the chairs is firm and steady with less space. Furthermore, since the wheel is at an outer side of the supporting leg, the wheel will suspended from a resisting section without contacting the resisting section of another chair. Thus no collision occurs to the wheel and thus the lifetime of the wheel is prolonged.
BACKGROUND OF THE INVENTIONIn many applications, the chairs are arranged temporarily for some activities, such as meeting, exhibition or performance. After end of the activity, the chairs are collected for storage. Generally, the chairs are stacked.
However most of the prior art chairs are not designed for stacking. For example most of the prior art chairs have four legs. These legs are almost vertical to the bottom of the seat so that it is almost impossible to stack the chairs one by one. In another prior art chair, the chair has only one leg with a disk like base for supporting on the ground. This kind of chairs are still not suitable for stacking.
Another kinds of chairs suitable for stacking are illustrated in
Accordingly, the primary object of the present invention is to provide a chair capable of being firmly stacked, wherein the stacking of the chairs is firm and steady, but occupies with less space. Furthermore, since the wheel is at an outer side of the supporting leg, the wheel will suspended from the resisting section without contacting the resisting section of another chair. Thus no collision occurs to the wheel and thus the lifetime of the wheel is prolonged.
To achieve above objects, the present invention provides a chair capable of being firmly stacked, comprising: a seat; at least one supporting leg being connected to a bottom of the seat, the supporting leg including a resisting section and a wheel assembly; one end of the resisting section being connected to a bottom of the seat and another end of the resisting section being connected to the wheel assembly; the wheel assembly including a connecting block and a wheel pivoted to the connecting block; one inner side of the connecting block being formed with a resisting groove; the wheel being installed at an outer side of the supporting leg and is rotatable with respect to the connecting block; the resisting groove having a shape corresponding to a periphery of the resisting section so that the resisting groove can receive the resisting section of another chair. In stacking, the seat of one chair is placed above the seat of another chair, while the resisting sections of the chair at the upper side resist against the resisting sections of the chair at the lower side.
Each resisting section is inclined to a bottom of the seat. The wheel is pivoted to the connecting block and the chair is shifted with the rotation of the wheel. A back portion is connected to the seat, each of two sides of the chair has a handle connected between the back portion and the seat. There are four supporting legs. The seat has a recessed central portion.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to
A seat 2 has an approximate flat rectangular shape and has a recessed central portion. The seat 2 serves to support the weight of the user. A back portion 21 is connected to the seat 2. The seat 2 and back portion 21 are formed as an approximate L shape. Each of two sides of the chair 1 has a handle 22 connected between the back portion 21 and the seat 2.
At least one supporting leg 3 is connected to a bottom of the seat 2. In this embodiment, four supporting legs 3 are installed to the seat 2. The supporting leg 3 includes a resisting section 32 and a wheel assembly 31. One end of the resisting section 32 is connected to a bottom of the seat 2 and another end of the resisting section 32 is connected to the wheel assembly 31. The wheel assembly 31 includes a connecting block 310 and a wheel 312 pivoted to the connecting block 310. One inner side of the connecting block 310 is formed with a resisting groove 311. The wheel 312 is installed at an outer side of the supporting leg 3. Preferably, the connecting block 310 has an approximate rectangular shape. The resisting groove 311 has a shape corresponding to a periphery of the resisting section 32 so that the resisting groove 311 can receive the resisting section 32 of another chair.
Referring to
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
Claims
