Abstract
A chair includes a backrest member, a seat member and a pair of armrest members. The backrest member has opposite lateral sides, upper and lower ends, and an intermediate portion between the upper and lower ends. The seat member has a rear end pivoted to the lower end of the backrest member. The armrest members are disposed on the lateral sides of the backrest member. Each of the armrest members has a rear end pivoted to the intermediate portion of the backrest member, and an outer wall surface formed with a mounting recess. Each of the armrest members includes a face panel disposed fittingly and detachably in the mounting recess.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a chair, more particularly to a chair having an armrest with a detachable decorative face panel so as to provide the chair with a changeable appearance.
2. Description of the Related Art
A conventional chair generally has a backrest member, a seat member having a rear end connected to the backrest member, a pair of armrest members having rear ends connected to the backrest member at opposite lateral sides of the backrest member, and front and rear legs. One possible way of changing the appearance of the armrest members is to attach a decorative patch thereon. However, an unpleasant appearance would be left on the armrest member when the patch is removed or when the patch has been put on the armrest member for a long period of time. It is desirable to provide a chair having an armrest member with a changeable appearance for enhanced consumer appeal.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a chair having an armrest with a detachable decorative face panel so as to provide a changeable appearance to the chair.
Accordingly, the chair of the present invention includes a backrest member, a seat member and a pair of armrest members. The backrest member has opposite lateral sides, upper and lower ends, and an intermediate portion between the upper and lower ends. The seat member has a rear end pivoted to the lower end of the backrest member. The armrest members are disposed on the lateral sides of the backrest member. Each of the armrest members has a rear end pivoted to the intermediate portion of the backrest member, and an outer wall surface formed with a mounting recess. Each of the armrest members includes a face panel disposed fittingly and detachably in the mounting recess.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 1 and 2
, the preferred embodiment of the chair according to the present invention is shown to include a backrest member
22
, a seat member
21
with a rear end portion pivoted to a lower end of the backrest member
22
, a pair of armrest members
4
extending forwardly from two opposite lateral sides of the backrest member
22
, and front and rear supports
31
,
32
adapted for supporting the chair on a ground surface.
The armrest members
4
are disposed respectively on the two lateral sides of the backrest member
22
, and have rear ends pivoted to the backrest member
22
by means of a pair of horizontal pivot pins
410
. Referring to
FIGS. 2 and 3
, each of the armrest members
4
has an outer wall surface formed with a mounting recess
411
. In the present embodiment, the mounting recess
411
is formed in a top side of a top wall
41
of the respective armrest member
4
. The top wall
41
is formed with a plurality of rectangular engaging holes
412
within the mounting recess
411
. Each of the armrest members
4
further has a decorative face panel
42
disposed fittingly and detachably in the mounting recess
411
. The top wall
41
and the face panel
42
are each formed from a plastic material. The face panel
42
is formed with a plurality of downward protrusions
422
which extend downwardly through the engaging holes
412
, respectively. Each of the downward protrusions
422
has a hooked distal end
423
for engaging releasably a bottom side of the top wall
41
. In the present embodiment, the face panel
42
has an inverted U-shaped cross-section, and may be provided with a label for indicating purposes. Preferably, the face panel
42
is in a color different from that of the top wall
41
, or is made from a material different from that of the top wall
41
so as to provide a different feeling of touch. Alternatively, the face panel
42
may be formed from a transparent plastic material, and a decorative piece (not shown) may be disposed within the mounting recess
411
between the face panel
42
and the top wall
41
so as to be visible through the face panel
42
.
Each of the armrest members
4
further has a parallel pair of positioning plates
43
which extend downwardly from the top wall
41
. The positioning plates
43
extend in a longitudinal direction of the armrest member
4
, and are spaced-apart in a transverse direction that is transverse to the longitudinal direction so as to define a downwardly opening longitudinal channel
44
therebetween. Each of the positioning plates
43
is formed with a plurality of locking grooves
432
that are displaced from one another in the longitudinal direction, and a slide slot
431
formed below and communicated with the locking grooves
432
. The locking grooves
432
are inclined forwardly and upwardly from the slide slot
431
. The slide slot
431
extends in the longitudinal direction of the respective armrest member
4
. The slide slot
431
and the locking grooves
432
in one of the positioning plates
43
are aligned respectively with the slide slot
431
and the locking grooves
432
in the other one of the positioning plates
43
.
The front support
6
includes two forwardly and downwardly inclined front legs
61
disposed on two opposite lateral sides of the seat member
21
. The front legs
61
have lower ends connected to each other by a front cross-bar
62
that is adapted to be disposed on a ground surface, upper ends
612
extending toward the armrest members
4
, respectively, and intermediate sections pivoted to a front end portion of the seat member
21
by means of a pair of pivot pins
311
. The rear support
3
includes two rearwardly and downwardly inclined rear legs
32
disposed respectively on the lateral sides of the seat member
21
. The rear legs
32
have lower ends connected to each other by means of a rear cross-bar
33
which is adapted to be disposed on the ground surface, upper ends
322
extending toward the armrest members
4
, respectively, and intermediate sections pivoted to the rear end portion of the seat member
21
by means of a pair of known pivot connectors
321
.
The upper ends
612
,
322
of the front and rear legs
61
,
32
are each formed as a circular disc with a pin hole
313
,
323
formed therethrough. The upper ends
612
,
322
of the front and rear legs
61
,
32
that are disposed at the respective one of the lateral sides of the seat member
21
extend into the longitudinal channel
44
of an adjacent one of the armrest members
4
, and are connected to each other by means of a connecting pin unit
5
which includes a pin portion
512
extending through the pin holes
313
,
323
, an enlarged head portion
511
secured to one end of the pin portion
512
, and a cover plate
52
fastened to an opposite end of the pin portion
512
by means of a screw member
53
. The pin portion
512
extends through the slide slots
431
in the positioning plates
43
of a respective one of the armrest members
4
. The enlarged head portions
511
and the cover plate
52
are disposed on two opposite lateral sides of the positioning plates
43
. The pin portion
512
is extendible into a selected one of the locking grooves
432
to permit adjustment in tilt of the backrest member
22
.
Referring to
FIG. 4
, to adjust the tilt of the backrest member
22
, the armrest members
4
are lifted to dispose the pin portions
512
in the slide slots
431
. Then, the armrest members
4
are moved forwardly or downwardly so as to enable the backrest member
22
to turn forward or rearward relative to the seat member
21
and so as to slide the pin portions
512
along the slide slots
431
. When the backrest member
22
is disposed at a desired inclination, the armrest members
4
are pushed downward to enable each of the pin portions
512
to extend into a selected pair of the locking grooves
432
in the respective armrest member
43
, thereby positioning the backrest member
22
at the desired inclination.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
