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.
