That is, the armrest 100 for a chair according to the present invention can accommodate articles such as writing instruments at a position closest to the user's hand, so that the accommodated articles can be used quickly and conveniently, and a separate writing instrument holder or writing instrument barrel does not need to be disposed at a narrow desk, thereby effectively utilizing the space on the desk.

In addition, as shown in fig. 2 to 7, the armrest 100 for a chair according to an embodiment of the present invention further includes a buffer member 130 provided on the arm cover 120. Accordingly, when the user puts the arm on the support arm cover 120, a sufficient cushion feeling can be provided.

In addition, as shown in fig. 2, 3, and 5 to 7, the armrest 100 for a chair according to an embodiment of the present invention may further include a cup holder 140. The cup holder 140 is a component for placing a cup. As shown in fig. 6 and 7, the cup holder 140 may be disposed between the upper end of the support part 6 and the arm supporting receptacle 110.

Accordingly, a cup (not shown) can be placed on the armrest 100 for a chair of the present invention closest to the user's hand by the cup holder 140, so that not only the cup placed can be used quickly and easily, but also it is not necessary to place the cup on a narrow table, thereby making effective use of the space on the desk.

For example, as shown in fig. 6 and 7, the cup holder 140 may include a holder main body 141 and one or more cup placing holes 142. The cup holder body 141 may have a plate shape, and the cup placing hole 142 may be formed in the cup holder body 141, and the cup may be placed in a form in which the cup is received.

Further, as shown in fig. 2, 3 and 6, the cup holder main body 141 may have the same size and the same shape as the bottom surface of the arm support accommodation box 110.

In addition, as shown in fig. 6 and 7, the armrest 100 for a chair according to an embodiment of the present invention may further include a box rotating part 150. As shown in fig. 6 and 7, the cartridge rotating part 150 can rotatably dispose the cup holder 140 in order to cover or expose the cup holder 140 to the outside by supporting the arm accommodating cartridge 110.

Accordingly, the cup holder 140 can be covered or exposed to the outside by rotatably supporting the arm accommodation box 110 by the box rotating part 150 (see fig. 7), so that the space occupied by the armrest 100 for a chair of the present invention can be effectively utilized by locating the cup holder 140 under the arm accommodation box 110 for supporting (see fig. 2) when the use of the cup holder 140 is not required.

For example, as shown in fig. 6 and 7, the cartridge rotating part 150 may include a vertical hinge shaft 151 and a vertical hinge hole 152. Wherein the vertical hinge shaft 151 may be provided on the cup holder main body 141 and perpendicular to the upper surface of the cup holder main body 141, and the vertical hinge hole 152 is provided in the arm support receiving box 110 and may be rotatably inserted into the vertical hinge shaft 151. Of course, although not shown, the vertical hinge shaft may be provided in the accommodating box for support, and the vertical hinge hole may be provided on the cup holder.

In addition, as shown in fig. 3 to 5, the armrest 100 for a chair according to an embodiment of the present invention may further include a cover rotating part 160, an elastic body 170 for opening, and a cover locking part 180.

The cover rotating part 160 may be provided to support the arm cover 120 to be rotatable to support the arm accommodating case 110. The opening elastic body 170 may be provided on the cover rotating part 160, and may apply elastic force in a direction in which the arm cover 120 is supported to be opened. The cover locking portion 180 may be disposed between the arm support accommodation box 110 and the arm support cover 120, and the arm support cover 120 may be in a closed state or an open state with respect to the upper open portion 112.

Accordingly, the arm cover 120 supported only by operating the cover locking part 180 can be automatically opened by the elastic force of the elastic body 170 for opening, and the arm cover 120 is not lost. When the user applies an opposite force, the support arm cover 120 may be automatically locked by the cover locking part 180.

For example, as shown in fig. 4, the cover locking portion 180 may include a locking member 181, a pinion gear (pinion)182, a first rack gear (first rack)183, a second rack gear (second rack)184, and a locking elastic body 185. The locking member 181 is provided to protrude from the bottom of the arm cover 120 and may have a locking hole 181 a. The pinion gear 182 may be rotatably provided in the arm supporting accommodation case 110, and the first rack gear 183 is engaged with the pinion gear 182 and corresponds to the locking hole 181a, and may have an insertion end 183 a. The second rack 184 is engaged with the pinion 182 and moves in the opposite direction to the first rack 183, and may have a pressing end 184a exposed to the outside of the accommodation box 110. The locking elastic body 185 may be disposed between the pinion gear 182 and the arm supporting accommodation box 110, and may apply a rotational force in a direction in which the insertion end 183a of the first rack gear 183 is inserted into the locking hole 181 a. Further, as shown in fig. 4, the upper face of the insertion end 183a may have a shape gradually inclined downward in the insertion direction of the insertion end 183 a.

Accordingly, if the user presses the pressing end 184a of the second rack 184, the insertion end 183a of the first rack 183 moved in the opposite direction by the pinion 182 is removed from the latching hole 181a, while the support cover 120 may be opened by the elastic force of the elastic body 170, and if the user closes the support arm cover 120, after the insertion end 183a of the first rack gear 183 is retreated backward by the pressure of the locking unit 181, the lock member 181 is further lowered so that the insertion end portion 181a is positioned in the locking hole 183a of the lock member 181, also, if the insertion end portion 183a is positioned in the locking hole 181a in this manner, while the insertion end portion 183a of the first rack 183 is moved in the direction of being inserted into the locking hole 181a by the elastic force of the locking elastic body 185, the support arm cover 120 can be held in a closed state by being caught in the catching hole 181 a.

Of course, although not shown, as another example, the cover locking portion may include: a locking member provided on a bottom surface of the arm cover and having a locking hole; a hook rotatably provided in the accommodation box for supporting an arm and corresponding to the locking hole; and a mechanism including a lock elastic body that applies a rotational force in a direction in which the hook is inserted into the locking hole.
