Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a chair, more particularly
one, of which the seat, the back, and the headrest can be easily
adjusted in position and angle such that the sitter can be
supported in a comfortable position.
[0003] 2. Brief Description of the Prior Art
[0004] Many chairs are made with adjustability and reclining
function so as to provide more comfort to the sitters. A common
conventional chair includes a seat for supporting a sitter's
buttocks, and a back for supporting the back; the seat and the back
each includes a main supporting part, a stuffing on the main
supporting part, and a piece of cloth member positioned over the
stuffing and connected to the main supporting part, which cloth
member can be cotton cloth, mesh or leather cloth. It will take
relatively much labor and time to separate the cloth member from
the main supporting part when the cloth member is dirty or broken,
and needs cleaning or replacement. Therefore, such chairs aren't
convenient to use.
[0005] Another common conventional back of a chair includes an
external frame part, and an internal frame part, which has a piece
of cloth member connected thereto for supporting a sitter's back,
and which is fitted in and secured to the external frame part by
means of screws. Therefore, it is easier to separate the internal
frame part from the external one for cleaning and repair.
[0006] However, such chair backs have a fixed shape, and can't be
adjusted in position and angle to suit people of different ages,
genders, and body heights. Therefore, the manufacturers have to
make a wide variety of models of chairs for suiting people of
different genders and various ages and body heights, causing
significant increase to the amount of inventory as well as the cost
of inventory management.
SUMMARY OF THE INVENTION
[0007] It is a main object of the invention to provide an
improvement on a chair to overcome the above-mentioned problem.
[0008] The chair of the present invention includes a seat, a back,
and a headrest. The back has several adjustment members thereon
while a supporting frame is connected to the adjustment members in
such a way as to be separable from the back; thus, position and
angle of the supporting frame can be adjusted for the chair to be
more comfortable by means of replacing the adjustment members with
other ones that have different dimensions from the original ones.
And, people are allowed to select and use another supporting frame
having different shape and size from the original one according to
their needs and situations. The seat and the headrest have the same
structure as the back so as to be easily adjusted and easily
disassembled for cleaning and repair.
[0009] Therefore, the manufacturers won't have to make chairs of
many different models, which are only slightly different in shape
and position for suiting people of different body heights, genders,
and ages, and in turn the amount of inventory and the cost of
inventory management will reduce.

[0017] FIG. 7 is a side view of the third preferred embodiment.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Referring to FIGS. 1 to 5, a first preferred embodiment 1 of
a chair of the present invention includes a seat 11, and a back 12.
The back 12 has several screw holes 121 spaced apart near to a
loop-shaped edge thereof, several adjustment members 13 spaced
apart near to the loop-shaped edge of a front side thereof, and a
supporting frame 14. The adjustment members 13 each have a through
hole 131, which is aligned with a respective one of the screw holes
121. The supporting frame 14 has several screw holes 141 thereon,
and it is positioned on front ends of the adjustment members 13
with the screw holes 141 thereof being aligned with respective ones
of the through holes 131 of the adjustment members 13. The
supporting frame 14 further has a piece of cloth 17 positioned over
a space within it, and securely connected thereto, which can be
cotton cloth, mesh, leather cloth or plastic cloth; in the present
embodiment, a mesh is used, which allows air to travel through it,
and is elastic and in fashion. Threaded connecting elements 15 are
passed through the screw holes 121, the through holes 131, and the
screw holes 141 such that the supporting frame 14 is secured in
place. Therefore, the supporting frame 14 can be easily removed for
replacement, cleaning or repair.
[0019] Furthermore, each of the screw holes 121 of the back 12 has
a plug 16 fitted in a rear end thereof; thus, there won't be any
cavity on the rear side of the back 12 to spoil the appearance of
the whole chair 1.
[0020] Therefore, position of the supporting frame 14 will be
changed when the original adjustment members 13 are replaced with
other adjustment members that have different dimensions from the
original ones 13. People are allowed to adjust the position and
angle of the supporting frame 14 according to their needs and
situations by means of selecting and using suitable adjustment
members 13, and they are allowed to select and use other supporting
frames having different shapes and sizes from the present one to
suit them. For example, referring to FIG. 3, if upper ones of the
adjustment members 13 are longer than lower ones of the adjustment
members 13, the supporting frame 14 will be at a particular angle,
which suits tall persons.
[0021] Referring to FIGS. 1 and 4, the adjustment members 13 and
the back 12 are formed together such that the adjustment members 13
can't be separated from the back 12 instead. And, the supporting
frame 14 is secured in place by means of passing threaded
connecting elements 15 through the screw holes 121 of the back 12,
the through holes 131 of the adjustment members 13, and the screw
holes 141 of the supporting frame 14. Therefore, the supporting
frame 14 can be easily separated from the adjustment members 13. Or
alternatively, referring to FIG. 5, the adjustment members 13 and
the supporting frame 14 can be formed together such that the
adjustment members 13 are inseparable from the supporting frame 14
instead.
[0022] Referring to FIG. 6, a second preferred embodiment 2 of a
chair of the present invention includes a seat 21, which has
several adjustment members 22 secured on an upper side thereof, and
a supporting frame 23 positioned over and separably connected to
the adjustment members 22. The supporting frame 23 has a cloth unit
24 positioned over a space within it, and securely connected
thereto Therefore, the supporting frame 23 can be easily removed
for replacement, repair or cleaning of the cloth 24. And, people
are allowed to adjust the position and angle of the supporting
frame 23 according to their needs and situations by means of
selecting and using suitable adjustment members 22, and they are
allowed to select and use other supporting frames having different
shapes and sizes from the present one to suit them.
[0023] Referring to FIG. 7, a third preferred embodiment 3 of a
chair of the present invention includes a back 32, and a headrest
31 connected to an upper end of the back 32. The headrest 31 has
several adjustment members 33 secured thereon, and a supporting
frame 34 positioned over and separably connected to the adjustment
members 33. Therefore, the supporting frame 34 can be easily
removed for replacement, repair or cleaning. And, people are
allowed to adjust the position and angle of the supporting frame 34
according to their needs and situations by means of selecting and
using suitable adjustment members 33, and they are allowed to
select and use other supporting frames having different shapes and
sizes from the present one to suit them.
[0024] From the above description, it can be easily seen that the
chair of the present invention has the following advantages: the
chair has a fashionable look, and the seat, the back, and the
headrest are easy to disassemble for cleaning and repair; position
and angle of the supporting frames can be easily adjusted by means
of selecting and using suitable adjustment members, and the
supporting frames can be replaced with other ones having different
shapes and sizes according to people's needs and situations; the
manufacturers won't have to make chairs of many different models,
which are only slightly different in shape and position, and in
turn the amount of inventory and the cost of inventory management
will reduce.
