Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a storable structure of
table and chair, and more particularly to a structure for storage
at least one chair under a table and lifting or lowering the chair
from the floor.
[0003] 2. Description of Related Art
[0004] A conventional combination table and chairs in accordance
with the prior art comprises a table which is supported by support
members extending from the table beyond the plane of the table and
connecting with the chair members, with the points of connection of
the support members to the table and chairs lying substantially in
a common vertical plane. The chair seat members are mounted for
movement in all directions in the plane of the seat.
[0005] However, the prior art suffered from several disadvantages.
Due to the complicated structure of the combination table and
chairs, the chairs are not able to be moved freely on the floor.
For the reason, a user can not easily move the chair to a suitable
position from the edge of the table. Moreover it is inefficient and
difficult to detach the chairs from the table since many tubular
supports are used in the combination of the table and chairs.
Therefore this is not convenient to store the chairs and save the
space.
[0006] The present invention has arisen to mitigate and/or obviate
the disadvantages of the conventional combination table and
chairs.
SUMMARY OF THE INVENTION
[0007] The main objective of the present invention is to provide an
improved storable structure of table and chair,
[0008] To achieve the objective, the storable structure of the
table and chair includes a tabletop and at least one chair member
positioned adjacent the tabletop. Each of the at least one chair
member includes a chair, a lifting device and a sliding device. The
lifting device connects to the chair for vertically lifting or
lowering the chair. When a force is applied downwardly to the
chair, the chair is lowered to adapt to abut against a floor so as
to be sat stably by a person, and when the force is released, the
chair is lifted upwardly by the lifting device. The sliding device
which connects to the lifting device and the tabletop has a guild
rail and a cantilever, the guide way is attached underneath the
tabletop. The cantilever connects the chair and the guide rail. The
chair slides horizontally along the guide rail so as to be storable
under the tabletop.
[0009] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Referring to the drawings and initially to FIGS. 1-4, a
storable structure of table and chair in accordance with a
preferred embodiment of the present invention comprises a tabletop
10 and at least one chair member 2 which positions adjacent the
tabletop 10.
[0017] Each of the at least one chair member 2 comprises a chair 20
and a lifting device 40 movably connected to the chair 20. The
chair 20 comprises a seat 21 and a chair base 22 having an upper
end pivotally attached to the seat 21. The chair base 22 has a
support post 221 which one end is used to vertically support the
seat 21 thereatop and the other end is mounted on a support base
222. The chair 20 has a plurality of casters 223 underneath the
support base 222 for abutting against a floor. Therefore the chair
20 moves freely on the floor via the casters 223.
[0018] The lifting device 40 movably connected to the chair base 22
is a spring member. The lifting device 40 comprises a vertical
sleeve 41 sleeved on the support post 221 and having a receiving
space 44 defined between the support post 221 and the vertical
sleeve 41. The lifting device 40 further includes a spring 43 and a
flange 42 which both are accommodated in the receiving space 44.
The spring 43 is compressible and sleeved on the support post 221.
One end of the spring 43 abuts against a bottom of the flange 42
and the other end of the spring 43 abuts against an inner bottom of
the vertical sleeve 41. The flange 42 is fixed to the support post
221 and thereby moves upwardly or downwardly with the chair 20.
When a force is applied downwardly, the chair 20 is lowered to abut
against the floor. The chair 20 is lifted upwardly by the spring 43
when the force is released.
[0019] The chair member 2 further comprises a sliding device 30
connected to the lifting device 40 and the tabletop 10. The sliding
device 30 comprises a guide rail 31 attached beneath the tabletop
10 and a cantilever 32 connected to the guide rail 31 and the
lifting device 40. The guide rail 31 has a T-shaped groove 311
forming at least one opening outwardly to the edge of the tabletop
10. The cantilever 31 has a first portion 321 corresponding to the
T-shaped groove 311, a vertical portion 323 and a second portion
322. Both end of the vertical portion 323 respectively connect to
the first portion 321 and the second portion 322 in an L shape, and
thus the first portion 321 is perpendicular to the second portion
322. The first portion 321 is parallelly received in the T-shaped
groove 311 and slidably moves along the T-shaped groove 311. The
second portion 322 attaches to the vertical sleeve 41 for
supporting the chair 20 away from the floor. Thereby the chair 20
slidably moves along the guild rail 31 relatively to the tabletop
10.
[0020] As shown in FIGS. 1-2, the vertical sleeve 41 of the lifting
device 40 is supported by the cantilever 32, and the spring 43 is
in unloaded condition. Therefore the chair 20 is held away from the
floor by the cantilever 32. Furthermore the chair 20 slidably moves
along the guide rail 31 by the sliding device 30 for storage under
the tabletop 10.
[0021] As shown in FIGS. 3-4, when a force is applied downwardly on
the seat 21, the flange 42 descends and thus compresses the spring
43. The chair 20 moves downwardly to abut against the floor so as
to be sat stably by a person. The spring 43 is compressed between
the flange 42 and the inner bottom of the vertical sleeve 41 which
is held by the cantilever 32. When the force is released, the
spring 43 pushes the flange 42 upwardly, and thus the chair 20 is
lifted by the spring 43.
[0022] Furthermore, the lifting device 40 is adjustable by
different loading. Thereby the chair 20 is suitable for persons in
different weight.
[0023] In another embodiment, the lifting device 40 may be a
pneumatic cylinder or a set of worm and gear.
[0024] FIG. 5 shows a second embodiment of a storable structure of
table and chair according to the present invention. The elements
and effects of the second embodiment which are the same with the
preferred embodiment are not described, only the differences are
described. The tabletop 10 is configured in a shape of square,
rectangular, or other configurations. In this embodiment, the
tabletop 10 is in the shape of square, and disposed four chair
members 2 at four sides of the tabletop 10 respectively. And each
of the chair members 2 has the chair 20 with a rest back 23. The
chair 20 is stored under the tabletop 10 and the rest back 23 of
the chair 20 abuts against the edge of the tabletop 10.
[0025] FIG. 6 is a general illustration of a third embodiment of a
storable structure of table and chair. The elements and effects of
the third embodiment which are the same with the preferred
embodiment are not described, only the differences are described.
The tabletop 10 is configured in a round shape. Ten chair members 2
are disposed to surround the tabletop 10, and each of the seats 21
is configured in a round shape.
[0026] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.
