Description
FIELD OF THE INVENTION
[0001] The present invention relates to a dismountable
chair assembly.
DESCRIPTION OF THE PRIOR ART
[0002] Prior chair with four feet usually has a welded
metal tube frames equipped with back cushion and seat
cushion, Such design has various styles depending on
different needs and ideas. However, the storage and cost
are the primary concerns for business or user.
[0003] Therefore, a dismountable chair is taking the
place of the conventional welded chair. Dismountable
chairs are preferable to the users by its simple structure,
lower cost, and easy and fast assembly or disassembly.
[0004] Known dismountable chairs usually include a
frame consisting of two H-shaped frames linked by twotransverse shafts. The H-shaped frame has a front chair
foot and a rear chair foot. The two H-shaped frames are
linked by the two transverse shafts by bolts so that a seat
cushion and a back cushion can be arranged to the chair
frame. However, such design has the following defects
and inconvenience.
1. The seat cushion is downwards buckled to the
chair frame. The seat cushion is easily departed or
loosened from the chair frame by frequently disas-
sembly or improper pick up of stacked chairs.
2. The back cushion is fixed to lateral shafts by bolts
and sleeves. Such design needs many components
to achieve.
3. The chair frame and the back cushion are assem-
bled by bolts, and the seat cushion is separately as-
sembled to the frame. The installation efficiency is
not good, and the assembly is also poor,
Examples of known dismountable chairs are described
in CN 2 287 842 Y and EP 1 616 505 A.
SUMMARY OF THE PRESENT INVENTION
[0005] Accordingly, the primary objects of the presentinvention are listed in the following.
1. To provide a simple-structured chair with lower
cost.
2. To provide a fast and easy assembly to user.
3. To provide a firm and stable chair having integral
seat cushion and frame.
4. To provide a chair occupying minimum space for
package and warehousing.
[0006] To achieve above objects, the assembly in-
cludes an H-shaped chair frame, back cushion, and a
seat cushion. A complete chair frame is formed by the
H-shaped chair frame, two inverse L-shaped front chair
feet, and a front transverse shaft.
[0007] The H-shaped chair frame has two upper shafts
and two rear feet transversely linked by a middle shaft,
The back cushion is arranged between the two upper
shafts. The middle shaft also serves to support the seat
cushion.[0008] The seat cushion has a round skirt on a bottom
side thereof.
According to the invention, two columns are formed to a
front side of the skirt for arranging the front transverse
shaft. Two open holes are formed to a rear side of the
skirt for being penetrated by the two inverse L-shaped
front chair feet. Two rear sides of the two inverse L-
shaped front chair feet can be fixed to the middle shaft
of the H-shaped chair frame by bolts.
[0009] The front transverse shaft has two receiving
holes on a front side thereof for receiving the two columns
of the seat cushion, Two ends of the front transverse
shaft are fixed to predetermined positions of the two in-verse L-shaped front chair feet respectively by bolts so
that the receiving holes are aligned with the columns.
