  Conventionally, there is a chair provided with a hanger for hanging clothes on the backrest. A chair equipped with such a hanger does not require the user to go to a hanger in a distant position when a seated person takes off his / her jacket and sits on it. Since it can be hung, it has the advantage that the jacket can be taken immediately when leaving the chair.

  However, such a chair with a hanger may get in the way when the hanger is not used because the hanger and its installation mechanism are greatly protruding from the back of the chair. Therefore, conventionally, there is a hanger-equipped chair in which the support for supporting the hanger can be slid in the vertical direction so that the hanger can be lowered in a situation where the hanger is not used.

  However, in such a vertical movement mechanism, the hanger support rod protrudes behind the backrest even when the hanger is lowered, and the hanger portion is not changed and is positioned above the backrest. For this reason, the problem that the appearance hanger and the unused hanger were obstructive was not solved completely.

  In view of the above-described problems, an object of the present invention is to provide a hanger unit that can retract the hanger part and does not get in the way at the retracted position.

  In order to solve the above-described problems, the present invention provides a hanger unit that can turn the support portion that supports the hanger portion so that the hanger portion can be retracted and does not get in the way at the retracted position. Made possible.

Specifically, the present invention is a hanger unit installed on a backrest of a chair, a base portion fixed to the backrest, a hanger portion on which an object is hung, and a support portion that supports the hanger portion. A support portion that is pivotably connected to the base portion so that the hanger portion is movable between a use position suitable for use as a hanger and a retracted position rotated from the use position; A hanger unit comprising

  In addition, a hanger unit is installed in a backrest and the location installed is a back part of a backrest normally. However, you may install in places other than a back part, such as a side part of a backrest. In addition, the base and the backrest may be separate members or a single member.

  Here, a use position is a position for a hanger part to be used as a hanger. When in the use position, the hanger portion is supported upward by the support portion. In order to prevent clothes or the like hung on the hanger part from touching the floor, the support part preferably supports the hanger part at a position higher than the base part in a state where the hanger part is in the use position.

  The retracted position is a position where the hanger part is retracted when the hanger part is not used as a hanger. In addition, it is possible to retreat a hanger part to the position which does not become a hindrance for a user completely by a support part supporting this hanger part in a position lower than a base part in the state in which a hanger part exists in a retracted position.

  In the present invention, the movement from the use position to the retracted position is realized by the rotation of the support portion. By moving the hanger part to the retracted position by the rotation of the support part, the positional relationship between the base part and the hanger part can be changed, unlike the position change by the conventional vertical movement mechanism. For this reason, according to the present invention, it is possible to prevent the hanger part from getting in the way at the retracted position.

  The direction of rotation may be substantially parallel to the back surface of the backrest. In general, since the back surface of the backrest is slightly inclined to the floor side from the vertical, the rotation surface of the support portion that is substantially parallel to the back surface is a surface inclined from the vertical. For this reason, the retracted position of the hanger part is dressed so as to be hidden under the back of the backrest and hidden, so that it does not get in the way of the user and the appearance can be made good.

  In addition, the hanger unit according to the present invention further includes a locking portion that locks the support portion, thereby preventing the hanger portion from moving from the use position or the retracted position. It may be movable from the use position or the retracted position in a state where the locking by the locking portion is released.

  Here, the movement may be blocked by the locking portion only at either the use position or the retracted position, or may be blocked at both positions. By providing such a locking portion, it is possible to prevent the hanger portion from moving by mistake due to the touch of the user's hand or the dead weight of the hanger portion.

  In addition, the hanger unit according to the present invention further includes a biasing portion that biases the support portion to lock the support portion to the locking portion, and the locking by the locking portion is the support. It may be released by applying an external force in a direction opposite to the biasing direction to the part.

Here, an elastic member such as a coil spring, a leaf spring, or rubber may be used for the urging portion. The locking portion is automatically locked by the urging force of the urging portion, thereby preventing the hanger portion from moving until a force in the direction opposite to the urging direction is applied by the user. When the force in the opposite direction is applied, the hanger part can be moved. That is, according to the present invention, it is possible to provide a hanger unit that can move the hanger part from the use position or the retracted position only when it is explicitly operated by the user.

  According to the present invention, it is possible to provide a hanger unit that can retract the hanger part and does not get in the way at the retracted position.

The base 11 has a shape that follows the shape of the upper back of the backrest 3 at a portion that contacts the back of the backrest 3, and is fixed to the upper back of the backrest 3 of the chair 2 using means such as screw fastening. For fixing, means other than screw fastening, for example, means such as adhesion may be employed. Moreover, the base 11 has the connection part 16 to which the support part 12 is connected to the opposite surface of the attachment surface. In the present embodiment, the connection portion 16 is a cylindrical hole having a screw hole at the center, and the base end 12a of the support portion 12 is rotatably screwed into the screw hole.

  The hanger portion 13 is a portion that plays a role as a hanger on which clothing or the like is hung, and has two arms that extend outward from the center. This arm has a shape that gradually curves down from the center toward the outside. In the present embodiment, the hanger portion 13 is formed integrally with the support portion 12. However, in this embodiment, the hanger part 13 and the support part 12 are one member integrally molded, but the hanger part 13 and the support part may consist of separate members.

  The support portion 12 is a rod-shaped member extending from the base end 12a to the hanger support end 12b, and the base end 12a is connected to the base portion 11 so as to be rotatable. In the present embodiment, the base end 12a of the support portion 12 has a shape corresponding to the connection portion 16 provided in the base portion 11, and a long hole 17 corresponding to the screw hole is provided at the center thereof. The long hole 17 is a long hole 17 having a size that passes through the shaft portion of the screw but cannot pass through the screw head, and the support portion 12 is connected to the base portion 11 by the screw due to the long hole 17. However, the support portion 12 can be slid with respect to the base portion 11 using the long hole 17. Further, although the screw is screwed into the screw hole of the base portion 11 but is not screwed to the inner surface of the long hole 17 of the base end 12 a of the support portion 12, the support portion 12 can be rotated with respect to the base portion 11. It is.

  Moreover, the support part 12 has the to-be-latched nail | claws 19a and 19b in the outer side, and the base 11 has the locking grooves 18a and 18b in two places around a cylindrical hole. In the present embodiment, the locked claws 19a and 19b are provided at one place (locked claw 19a) on the upper side of the base end 12a of the support portion 12, and one place (locked claw 19b) on the lower side. The locking grooves 18a and 18b are provided at one position (the locking groove 18a) at the upper edge of the cylindrical hole and at one position (the locking groove 18b) at the lower edge.

  By doing so, in a state where the hanger portion 13 is in the use position (that is, a state where the support portion 12 extends upward from the base end 12a), the to-be-latched claw 19a is placed in the upper retaining groove 18a. In a state where the portion 13 is in the retracted position (that is, a state in which the support portion 12 is directed downward from the base end 12a), the locked claw 19a can be locked in the lower locking groove 18b. Similarly, when the hanger portion 13 is in the use position, the locked claw 19b is in the lower locking groove 18b, and when the hanger portion 13 is in the retracted position, the locked claw 19b is in the upper locking groove 18a. To be locked.

  Between the base part 11 and the support part 12, an urging part for urging the support part 12 to lock the locked claws 19a, 19b of the support part 12 in the locking grooves 18a, 18b is provided. . In the present embodiment, the urging portion is a member in which an elastic member (coil spring 15) is provided on the semicircular member 14, and the cylindrical hole (connection) of the base 11 together with the base end 12a of the support portion 12 constituting the remaining semicircle. Part 16) (see FIG. 4).

  By providing such an urging portion between the base portion 11 and the support portion 12, one end of the coil spring 15 is urged toward the support portion 12, and the other end of the coil spring 15 is interposed via the semicircular member 14. The inner surface of the cylindrical hole is biased. For this reason, in a state where the hanger portion 13 is in the use position (that is, in a state where the support portion 12 extends upward from the base end 12a), the support portion 12 is pushed downward, and the claws 19a and 19b are lowered. Thus, it is locked in the locking grooves 18a and 18b. Further, when the hanger portion 13 is in the retracted position (that is, when the support portion 12 faces downward from the base end 12a), the support portion 12 is pushed upward, and the locked claws 19b and 19a are raised. Locked in the locking grooves 18a and 18b. That is, in the hanger unit 1 according to the present embodiment, the hanger unit 1 includes the urging portion, so that when the hanger portion 13 is in the use position and the retracted position, the locking portions 18a and 18b rotate the locking portion. Movement is blocked.

  Next, an operation method of the hanger unit 1 according to the present embodiment will be described. 5A to 5E are views showing the state of the hanger unit 1 at each stage of the operation procedure of the hanger unit 1 according to the present embodiment. Here, the description starts from the case where the hanger portion 13 is in the use position. FIG. 6A is a transparent perspective view showing a connection state between the support portion 12 and the base portion 11 when the hanger portion 13 in the present embodiment is in the use position. When the hanger portion 13 is in the use position, the hanger portion 13 is supported by the support portion 12 at a position higher than the base portion 11. Further, when the support portion 12 is urged by the urging portion, the to-be-latched claws 19a and 19b are locked to the locking grooves 18a and 18b, and the rotation of the support portion 12 is prevented (see FIG. 5A). reference).

  Here, when the user holds the hanger part 13 or the support part 12 and pulls it upward, the urging part has a force in a direction opposite to the direction of urging by the urging part (that is, the force pushing the supporting part 12 downward). As a result, the support portion 12 moves upward, and the locking by the locking grooves 18a and 18b is released accordingly (see FIG. 5B). FIG. 7 is a perspective view showing a state of the locking groove 18a and the locked claw 19a when the hanger unit 1 in the present embodiment is unlocked from the use position.

  FIG. 6B is a transparent perspective view illustrating a connection state between the support portion 12 and the base portion 11 when the hanger unit 1 in the present embodiment is unlocked from the use position. In a state where the lock is released, the user rotates the support portion 12, that is, moves the hanger portion 13. In this embodiment, the support portion 12 is connected to the base portion 11 so as to rotate about an axis substantially perpendicular to the back surface of the backrest 3, and rotates substantially parallel to the back surface of the backrest 3 (FIGS. 5C and 6C). See). In addition, although FIG. 5C depicts a state of rotating rightward from the back of the chair 2, the rotation may be either left rotation or right rotation.

  When the support portion 12 rotates 180 degrees, the locked claw 19a of the support portion 12 moves to a position where it can be locked in a locking groove 18b provided on the lower edge of the cylindrical hole (see FIG. 5D). ). Similarly, the nail | claw 19b to be moved moves to the position which can be latched in the latching groove 18a provided in the upper edge of the cylindrical hole. FIG. 6D is a transparent perspective view illustrating a connection state between the support portion 12 and the base portion 11 in a state where the hanger unit 1 in the present embodiment is unlocked from the retracted position. Here, the urging portion rotates 180 degrees together with the support portion 12 and pushes the support portion 12 upward. For this reason, the support part 12 moves upward by the urging force of the urging part, and the to-be-latched claw 19a is latched in the latching groove 18b provided on the lower edge of the cylindrical hole. Similarly, the to-be-latched claw 19b is latched by the latching groove 18a provided in the lower edge of the cylindrical hole. In this state, the hanger part 13 completes the movement from the use position to the retracted position (see FIG. 5E).

  FIG. 6E is a transparent perspective view showing a connection state between the support portion 12 and the base portion 11 when the hanger portion 13 in the present embodiment is in the retracted position. According to this embodiment, when the hanger part 13 is moved to the retracted position, the hanger does not get in the way when the hanger is not used. In particular, the hanger part 13 is moved to a position lower than the base part 11, so that the appearance is not impaired and the user does not get in the way compared to a chair-mounted hanger of a type that is moved above the conventional base part. Can be obtained.

  In addition, the hanger part 13 in the retracted position can be moved to the use position by performing a procedure reverse to the procedure described above. That is, the user releases the lock by holding the hanger part 13 or the support part 12 in the retracted position and pulling it downward, and rotates the support part 12 180 degrees so that the hanger part 13 is positioned above the base part 11. Then, the hanger part 13 can be moved to the use position by releasing the hand and engaging the locked claws 19a, 19b with the locking grooves 18a, 18b provided at the edge of the cylindrical hole.

  In addition, the length of the support part 12 which concerns on this embodiment is determined so that the hanger part 13 can be supported to the height more than predetermined from a floor. That is, the total length of the support portion 12 from the floor to the base portion 11 and the height from the base portion 11 to the hanger portion 13 in use is larger than the length of the clothes hung on the hanger portion 13. To be determined. FIG. 8 is a side view of the chair 2 provided with the hanger unit 1 (use position) according to the present embodiment. By doing in this way, when clothes are hung on the hanger part 13 in a use position, clothes can be prevented from sticking to a floor.

  In conventional chair-mounted hangers, if the position of the hangers is made high so that they do not touch the floor even when long clothes are hung, the support becomes long, and the appearance is impaired when the hangers are not used, which disturbs the user. appear. In addition, for example, even if a vertical movement mechanism that slides the support part downward is provided, the long support part extends downwardly, because the appearance is impaired, and the lowered hanger is eventually above the base part, The problem of hung hangers not being used is not completely solved.

  On the other hand, according to the hanger unit 1 according to the present embodiment, the hanger is moved to a position lower than the base 11 by the rotation mechanism, so that the hanger is moved from a position that is an obstacle to the user without deteriorating the appearance. It becomes possible. FIG. 9 is a side view of the chair 2 provided with the hanger unit 1 (retracted position) according to the present embodiment. In general, since the back surface of the backrest 3 is slightly inclined to the floor side from the vertical, when the hanger unit 1 is installed on such a chair 2, the rotation surface of the support 12 that is substantially parallel to the back surface is inclined more than the vertical. It becomes the surface. For this reason, the retreat position of the hanger part 13 becomes the appearance which is hidden under the back of the backrest 3 and is hidden, so that it does not get in the way of the user and the appearance can be made good.
