BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an armrest assembly for a chair, and more particularly to an angle adjustable armrest assembly. [0003] 2. Description of the Related Art [0004] A conventional chair comprises a seat, a backrest mounted on the rear end of the seat, and two armrests mounted on the two opposite sides of the seat. However, each of the two armrests is secured on the seat, so that each of the two armrests cannot be swiveled to adjust its horizontal swivel angle so as to fit the practical requirement of different users, thereby easily causing an uncomfortable sensation to the users. SUMMARY OF THE INVENTION [0005] The primary objective of the present invention is to provide an angle adjustable armrest assembly. [0006] Another objective of the present invention is to provide an armrest assembly, wherein the armrest plate is rotatable relative to the armrest support to change the angle between the armrest plate and the armrest support so as to change the horizontal swivel angle of the armrest assembly. [0007] A further objective of the present invention is to provide an armrest assembly, wherein the horizontal swivel angle of the armrest assembly is adjusted freely to fit the practical requirement of different users, thereby providing a comfortable sensation to the users. [0008] Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0009] FIG. 1 is a perspective view of an armrest assembly in accordance with the preferred embodiment of the present invention; [0010] FIG. 2 is a partially perspective view of the armrest assembly as shown in FIG. 1; [0011] FIG. 3 is an exploded perspective view of the armrest assembly as shown in FIG. 1; [0012] FIG. 4 is a top plan cross-sectional view of the armrest assembly as shown in FIG. 1; [0013] FIG. 5 is a schematic operational view of the armrest assembly as shown in FIG. 1 in use; [0014] FIG. 6 is a schematic operational view of the armrest assembly as shown in FIG. 4 in use; [0015] FIG. 7 is a partially perspective view of an armrest assembly in accordance with another preferred embodiment of the present invention; [0016] FIG. 8 is a perspective view of an armrest assembly in accordance with another preferred embodiment of the present invention; and [0017] FIG. 9 is a partially perspective view of the armrest assembly as shown in FIG. 8. DETAILED DESCRIPTION OF THE INVENTION [0018] Referring to the drawings and initially to FIGS. 1-4, an armrest assembly in accordance with the preferred embodiment of the present invention comprises an armrest support 1, a cover plate 2 mounted on a top of the armrest support 1 and having a rear end provided with a positioning shaft 21, a rotation plate 3 rotatably mounted on the positioning shaft 21 of the cover plate 2, an armrest plate 6 secured on the rotation plate 3 to rotate relative to the armrest support 1, a positioning block 4 secured on the positioning shaft 21 of the cover plate 2 and having a periphery formed with a plurality of locking grooves 42, a locking barrel 5 secured on the rotation plate 3 to rotate therewith and elastically engaged with the locking grooves 42 of the positioning block 4 to provide a positioning effect to the rotation plate 3 when the armrest plate 6 is rotatable relative to the armrest support 1. [0019] The rotation plate 3 is an elongated plate rested on the cover plate 2 and has a pivot hole 31 pivotally mounted on the positioning shaft 21 of the cover plate 2. [0020] The positioning block 4 is rested on the rotation plate 3 axially and has a shaft hole 41 secured on the positioning shaft 21 of the cover plate 2. The periphery of the positioning block 4 has an arc-shaped face formed with the locking grooves 42. Continue reading about Angle adjustable armrest assembly...
