Abstract
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.
Description
- 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.
- In 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
FIGS. 8 and 10 , the prior art has four legs which are installed to a bottom of a seat and at an end of each leg near the ground is installed with a wheel. The wheel is pivoted to the leg and is freely rotatably with respect to the leg. The stacking of these kinds of chairs is illustrated inFIGS. 9 and 10 . It is shown that in stacking, the chair at the upper side cannot firmly retain to the chair at the lower side. Moreover, as the chairs stack one by one, the stacking will incline with the extent of the height of the stacking so that the stacking of the chairs are not steady. It is very possible that the chairs fall down to the ground so that the worker must stack the chairs again. Furthermore, referring toFIG. 10 , in the prior art, the wheel is at a right lower side of the leg. In stacking the wheels will be in contact with legs of another chair (seeFIGS. 9 and 10 ). For a long time, the wheels will destroy so as to reduce the lifetime of the chair. - 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.

FIG. 1 is a schematic perspective view of the chair capable of being firmly stacked according to the present invention. -
FIG. 2 is an enlarged schematic view of the chair of the present invention. -

FIG. 8 shows the stacking of the prior art chairs. -
FIG. 9 shows another stacking state of the prior art chairs. -
FIG. 10 is an enlarged schematic view showing the wheel of the chair according to the present invention. - 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
FIGS. 1 to 3 , the structure of thechair 1 of the present invention is illustrated. The present invention has the following structure. - A
seat 2 has an approximate flat rectangular shape and has a recessed central portion. Theseat 2 serves to support the weight of the user. Aback portion 21 is connected to theseat 2. Theseat 2 andback portion 21 are formed as an approximate L shape. Each of two sides of thechair 1 has ahandle 22 connected between theback portion 21 and theseat 2. - At least one supporting
leg 3 is connected to a bottom of theseat 2. In this embodiment, four supportinglegs 3 are installed to theseat 2. The supportingleg 3 includes a resistingsection 32 and awheel assembly 31. One end of the resistingsection 32 is connected to a bottom of theseat 2 and another end of the resistingsection 32 is connected to thewheel assembly 31. Thewheel assembly 31 includes a connectingblock 310 and awheel 312 pivoted to the connectingblock 310. One inner side of the connectingblock 310 is formed with a resistinggroove 311. Thewheel 312 is installed at an outer side of the supportingleg 3. Preferably, the connectingblock 310 has an approximate rectangular shape. The resistinggroove 311 has a shape corresponding to a periphery of the resistingsection 32 so that the resistinggroove 311 can receive the resistingsection 32 of another chair. - Referring to
FIGS. 4 to 7 , the application of the present invention is illustrated. In stacking, theseat 2 of onechair 1 is placed above theseat 2 of anotherchair 1, while the resistingsections 32 of thechair 1 at the upper side resists against the resistingsections 32 of thechair 1 at the lower side. Moreover, since the resistinggroove 311 is at an inner side of the supportingleg 3, the resistinggroove 311 of one resistingsection 32 of thechair 1 at the upper side receives a part of the resistingsection 32 of thechair 1 at the loser side. As a result, the stacking of the chairs is firm and steady. Furthermore, the stacking of the chairs according to the present invention occupies less space. Since thewheel 312 is at an outer side of the supportingleg 3. thewheel 312 will suspended from the resistingsection 32 without contacting the resistingsection 32 of another chair. Thus no collision occurs to thewheel 312 and thus the lifetime of thewheel 312 is prolonged. - 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.
