Therefore, when the user places the arm on thearm rest cover 120, a sufficient cushioning feeling may be provided. - In addition, the
armrest 100 for the chair according to the exemplary embodiment of the present invention may further include acup holder 140, as illustrated inFIGS. 2, 3 , and 5 to 7. Thecup holder 140 is a component for holding the cup. As illustrated inFIGS. 6 and 7 , thecup holder 140 may be provided between the upper end of thesupporter 6 and the receivingcase 110 for supporting the arm. - Accordingly, a cup (not illustrated) can be held on the
armrest 100 for the chair of the present invention closest to the user's hand through thecup holder 140, so that the held cup may be not only used quickly and easily and a space on the desk may also be efficiently used even if the cup is not placed on the narrow desk. - For example, as illustrated in
FIGS. 6 and 7 , thecup holder 140 may include acup holder body 141 and one or more cup seating holes 142. Thecup holder body 141 may have a plate shape, and thecup seating hole 142 may be formed in thecup holder body 141 and the cup may be seated in the form in which the cup is accommodated. - Furthermore, the
cup holder body 141 may have the same size and the same shape as the bottom surface of the receivingcase 110 for supporting the arm, as illustrated inFIGS. 2, 3 and 6 . - In addition, as illustrated in
FIGS. 6 and 7 , thearmrest 100 for the chair according to the exemplary embodiment of the present invention may further include acase rotating part 150. As illustrated inFIGS. 6 and 7 , thecase rotating part 150 may rotatably provide the receivingcase 110 for supporting the arm on thecup holder 140 so that thecup holder 140 is covered or exposed to the outside by the receivingcase 110 for supporting the arm. - Therefore, the
cup holder 140 may be covered or exposed to the outside by rotating the receivingcase 110 for supporting the arm through the case rotating part 150 (seeFIG. 7 ), and when the use of thecup holder 140 is not required, thecup holder 140 is positioned under the receivingcase 110 for supporting the arm (seeFIG. 2 ), so as to efficiently use a space occupied by thearmrest 100 for the chair of the present invention. - For example, the
case rotating part 150 may include avertical hinge shaft 151 and avertical hinge hole 152 as illustrated inFIGS. 6 and 7 . Thevertical hinge shaft 151 is provided on thecup holder body 141 and may be vertically provided on the upper surface of thecup holder body 141, and thevertical hinge hole 152 is provided in the receivingcase 110 for supporting the arm and may be rotatably inserted into thevertical hinge shaft 151. Of course, although not illustrated, the vertical hinge shaft may be provided in the receiving case for supporting the arm, and the vertical hinge hole may also be provided in the cup holder. - In addition, as illustrated in
FIGS. 3 to 5 , thearmrest 100 for the chair according to the exemplary embodiment of the present invention may further include acover rotating part 160, an openingelastic body 170, and acover locking part 180. - The
cover rotating part 160 may rotatably provide thearm rest cover 120 to the receivingcase 110 for supporting the arm, and the openingelastic body 170 may be provided on thecover rotating part 160, and may apply an elastic force in a direction in which thearm rest cover 120 is opened. Thecover locking part 180 may be provided between the receivingcase 110 for supporting the arm and thearm rest cover 120, and thearm rest cover 120 may be in a closed or open state with respect to theupper opening part 112. - Accordingly, the
arm rest cover 120 may be automatically opened by the elastic force of the openingelastic body 170 only by manipulation of thecover locking part 180 without loss of thearm rest cover 120, and thearm rest cover 120 may be automatically locked by thecover locking part 180 while the user applies an opposite force. - For example, the
cover locking part 180, as illustrated inFIG. 4 , may include a lockingmember 181, apinion 182, afirst rack 183, asecond rack 184, and an engagingelastic body 185. The lockingmember 181 may be provided to protrude from the bottom surface of thearm rest cover 120 and may have alocking hole 181 a. Thepinion 182 may be rotatably provided in the receivingcase 110 for supporting the arm, thefirst rack 183 may be engaged with thepinion 182 and have aninsertion end 183 a corresponding to thelocking hole 181 a, and thesecond rack 184 is engaged with thepinion 182 and moves in an opposite direction to thefirst rack 183, and may have apressing end 184 a exposed to the outside of the receivingcase 110 for supporting the arm. The lockingelastic body 185 may be provided between thepinion 182 and the receivingcase 110 for supporting the arm, and may apply a rotational force in a direction in which theinsertion end 183 a of thefirst rack 183 is inserted into thelocking hole 181 a. Furthermore, the upper surface of theinsertion end 183 a may have a shape that is gradually inclined downward in the insertion direction of theinsertion end 183 a, as illustrated inFIG. 4 . - Accordingly, when the user presses a
pressing end 184 a of thesecond rack 184, theinsertion end 183 a of thefirst rack 183 that is moved in the opposite direction through thepinion 182 is removed from the lockinghole 181 a and at the same time, thearm rest cover 120 may be opened by the elastic force of the openingelastic body 170. When the user closes thearm rest cover 120, theinsertion end 183 a of thefirst rack 183 is retracted backward by the pressing force of the lockingmember 181, and then the lockingmember 181 further comes down so that theinsertion end 183 a may be positioned in the engaginghole 181 a of the lockingmember 181. As such, when theinsertion end 183 a is positioned in thelocking hole 181 a, theinsertion end 183 a of thefirst rack 183 is moved in the direction to be inserted into thelocking hole 181 a by the elastic force of the lockingelastic body 185, and at the same time, is caught in thelocking hole 181 a so that thearm rest cover 120 may be maintained in a closed state. - Of course, although not illustrated, as another example, the cover locking part may also have a mechanism including a locking member provided on the bottom surface of the arm rest cover and having a locking hole, a hook provided rotatably on the receiving case for supporting the arm and corresponding to the locking hole, and a locking elastic body applying a rotational force in the direction in which the hook is inserted into the locking hole.
- While the preferred exemplary embodiment of the present invention has been described in detail, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using a basic concept of the present invention defined in the appended claims also belong to the scope of the present invention.
- The present invention relates to a chair, and has industrial applicability.
