Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a seat of a chair, more
particularly one, which includes a frame, and a cushion member
capable of sinking into a space within the frame.
[0003] 2. Brief Description of the Prior Art
[0004] Referring to FIGS. 1 and 2, a conventional seat 10 of a
chair such as a swivel office chair, and a bar stool includes a
soft cushion part 101, and a hard board part 102. The soft cushion
part 101 has certain softness and thickness so that it will sink
when one person is seated thereon. And, the soft cushion part 101
the same width and length as the hard board part 102. The hard
board part 102 is secured on a bottom of the soft cushion part 101,
and connected to a leg 20 of a chair.
[0005] The soft cushion part 101 is used to provide
comfortableness. However, the soft cushion part 101 usually will
sink to such a degree as to touch the hard board part 102 when
people are seated on the seat 10. Consequently, the sitters'
buttocks will touch the hard board part 102, and the sitters feel
uncomfortable, and have improper body posture and poor blood
circulation eventually.
SUMMARY OF THE INVENTION
[0006] It is a main object of the invention to provide an
improvement on a seat of a chair to overcome the above
disadvantages.
[0007] The seat of the invention includes a frame, and a cushion
member. The frame includes an upper loop-shaped part, and a lower
part connected to the upper loop-shaped part. The lower part has
such a shape as to have a space within it, which is under and in
communication with a space within the upper loop-shaped part. The
cushion member includes several elastic elements, a soft part, and
a mesh-like part. The elastic elements is positioned across and
connected to the upper loop-shaped part at two ends while the soft
part is positioned over the upper loop-shaped part. The mesh-like
part is positioned over the soft part and the upper loop-shaped
part to hold the soft part in position; thus, the cushion member is
allowed to sink into the space within the lower part of the frame
when one heavy person is seated on the seat.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The present invention will be better understood by referring
to the accompanying drawings, wherein:
[0009] FIG. 1 is a perspective view of the conventional swivel
office chair as described in Background,
[0010] FIG. 2 is a front view of the conventional bar stool,
[0011] FIG. 3 is a fragmentary perspective view of the first
embodiment of a seat in the present invention,
[0012] FIG. 4 is a vertical sectional view of the first embodiment
of a seat.
[0013] FIG. 5 is a fragmentary perspective view of the second
embodiment of a seat in the present invention, and
[0014] FIG. 6 is a vertical sectional view of the fourth embodiment
of a seat in the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Referring to FIG. 3, a first embodiment 1 of a seat of a
chair includes a frame 11, and a cushion member 13.
[0016] The frame 11 includes an upper loop-shaped part 111, and a
lower part 112. The lower part 112 of the frame 11 is connected to
the upper loop-shaped part 111, and a leg 20 of a chair such as a
swivel office chair as shown in FIGS. 3 and 5. Furthermore, the
lower part 112 of the frame 11 has such a shape as to have a space
113 within it, which is right under and in communication with a
space within the upper loop-shaped part 111.
[0017] The cushion member 13 includes several elastic elements 131,
a soft part 132, and a mesh-like part 133. Two ends of each of the
elastic elements 131 are bent downwards, and the elastic elements
131 are positioned across and inserted into the upper loop-shaped
part 111 of the frame 11 at the downwards bent ends.
[0018] The soft part 132 is made of soft material such as sponge,
and has a certain thickness. And, the soft part 132 is positioned
on the upper loop-shaped part 111 of the frame 11, and it has such
dimensions that the soft part 132 will encompass the upper
loop-shaped part 111.
[0019] The mesh-like part 133 has very good elasticity, and it is
positioned over the soft part 132 and the upper loop-shaped part
111 of the frame 11, and connected to the upper loop-shaped part
111 so as to hold the soft part 132 in position.
[0020] Because of the elastic elements 131, the seat 1 will provide
more elasticity than the soft part 132 will alone. And, because of
the space within the upper loop-shaped part 111 and the space 113
within the lower part 112 of the frame 11, the cushion member 13 is
allowed to sink a relatively long distance into the space within
the lower part 112 of the frame 11 when one heavy person is seated
on the cushion member 13. Consequently, the seat is comfortable to
sit on.
[0021] Referring to FIG. 5, the cushion member 13 of the seat of
the invention has the soft part 132 and the mesh-like part 133, but
is doesn't have the elastic elements 131. Although the cushion
member 13 doesn't have the elastic elements 131, it still has
enough elasticity. Moreover, the mesh-like part 133 can be
positioned over and connected to the upper loop-shaped part 111 of
the frame 11 alone to make a comfortable seat.
[0022] Referring to FIG. 6, a fourth embodiment of a seat, which is
suitable for use on a bar stool, includes a frame, a mesh-like part
133, and a soft part 14, which frame has substantially the same
structure as the frame 11 of the seat of the first embodiment,
including an upper loop-shaped part 111, and a lower part 112 plus
having a space within the upper loop-shaped part 111 and a space
113 within the lower part 112, which is right under and in
communication with the space within the upper loop-shaped part 111;
the soft part 132 is positioned on top of the upper loop-shaped
part 111 of the frame while the mesh-like part 133 is positioned
over the upper loop-shaped part 111. Thus, the seat has good
elasticity, and is comfortable to sit on.
[0023] From the above description, it can be understood that the
seats of the present invention have more elasticity, and are more
comfortable to sit on than the conventional seat as described in
Background.
