Moreover, assembling these parts is facilitated by assembling the protruding portion into the insertion notch formed in the casing body.

One embodiment of a hanger hook will be described with reference to FIGS. The hanger hook 1 has a vertical direction Y and a horizontal direction X orthogonal thereto.
FIG. 1 is a perspective view when the hanger hook 1 is attached to the wall 2. The state in which the hook 3 is housed in the hook casing 4 is indicated by a solid line, and the hook 3 is indicated by a virtual line from the upper side to the lower side in the vertical direction Y. The state which turned toward is shown. 2 is an exploded view of the hanger hook 2, FIG. 3 is a front view of the hanger hook 1, FIG. 4 is a rear view of the hanger hook, FIG. 5 is a cross-sectional view taken along the line V-V in FIG. FIG. 7 is a sectional view of the rotary damper 35.

  As shown in FIGS. 1 to 6, the hanger hook 1 includes a hook 3 on which clothes can be put and extends in the longitudinal direction Y, and a hook casing 4 in which the hook 3 is accommodated. The hook 3 is projected and used. The hook 3 is positioned at the base end portion 5 attached to the hook casing 4 so that one end in the vertical direction Y can pivot, the arm portion 6 extending from the base end portion 5 in the vertical direction Y, and the tip of the arm portion 6. And a tip portion 7 that forms a convex portion 7a toward the hook casing 4 side.

  The hook casing 4 includes a casing body 15 and a cover 16. The casing body 15 includes a bottom surface 18, an outer peripheral wall 19 that stands up from the bottom surface 18, and an opening 20 that faces the bottom surface 18 through the outer peripheral wall 19. The opening 20 extends outward from the outer peripheral wall 19 substantially vertically. An extending flange 21 is formed. The hook casing 4 is attached to a building wall or the like, but the cover 21, the bottom surface 18 and the outer peripheral wall 19 are embedded in the building, and the flange 21 is placed on the building wall so that the opening 20 is located on the building wall. Etc.

  A pair of bearings 9 that support the hook rotation shaft 8 are formed on the outer peripheral wall 19 of the casing body 15, and an insertion notch 22 is formed around the bottom face 18 and the outer periphery so that the hook 3 can be inserted into the bearing 9. A part of the wall 19 is formed. A cover 16 is attached to the bottom surface 18 of the casing body 15 so as to close these insertion notches 22. The cover 16 is formed with a screw hole 24 that can be joined to the bottom surface 18, and a screw 26 is screwed into the casing body 15 through the screw hole 24 to couple the casing body 15 and the cover 16. Further, the cover 16 is formed with a mounting hole 27 for fixing a mounting bracket (not shown), and the hook casing 4 including the casing main body 15 and the cover 16 is attached to the building via the bracket.

  The cover 16 includes a contact surface 30 that contacts the bottom surface 18 of the casing body 15, a pair of protrusions 31 that protrude from the contact surface 30 into the casing body 15 at substantially right angles to close the insertion hole 22, and the protrusions 31. And a rack 32 positioned between the lateral directions X. The rack 32 is formed so as to protrude from the contact surface 30 into the casing body 15 at a substantially right angle.

The rack 32 meshes with a gear 36 formed on the rotary damper 35.
As shown in FIG. 7, the rotary damper 35 includes a damper casing 46, a cap 47 that covers the opening of the damper casing 46, a rotating body 48 that rotates inside the damper casing 46, and a damper that is integral with the rotating body 48. A rotation shaft 49. The damper rotating shaft 49 can rotate integrally with the rotating body 48, and one end of the damper rotating shaft 49 extends outside the damper casing 46. The gear 36 is fixed to an extended end of the damper rotating shaft 49, and the damper rotating shaft 49, the gear 36 and the rotating body 48 are integrally rotatable relative to the damper casing 46. When the damper casing 46 is filled with the viscous fluid 50 and the rotating body 48 rotates relative to the damper casing 46, the viscous fluid 50 exhibits viscous resistance against the rotation of the rotating body 48.
A screw hole 41 is formed in the damper casing 46, and the rotary damper 35 is fixed to the hook 3 by the screw 42.

  The hook 3 is pivotally attached to the hook casing 4 by inserting a hook rotating shaft 8 positioned at the base end portion 5 into a bearing 9 formed in the hook casing 4. The hook 3 includes an inner surface 11 located on the hook casing 4 side and an outer surface 12 opposite to the inner surface 11, and is a base end portion 5 of the hook 3, and a pressing portion 13 protruding from the outer surface 12 is formed on the outer surface 12. ing. By pressing the pressing portion 13 against the inner surface 11 side, the hook 3 can be turned from the upper side in the vertical direction Y to the lower side so as to protrude to the outside of the hook casing 4. When the hook 3 turns from the hook casing 4, the convex portion 7 a of the tip end portion 7 is exposed, and when the clothes or the like are put on the arm portion 6, the convex portion 7 a prevents the clothes or the like from sliding off the arm portion 6. Can do.

  The hook 3 includes a pair of wall surfaces 39 standing upright from the outer surface 12 in the casing body 15. The wall surface 39 extends along the longitudinal direction Y with respect to the outer peripheral wall 19 of the casing body 15 when the hook 3 is stored. A rotary damper 35 is attached to one of the wall surfaces 39 by a screw 42. At this time, the hook rotating shaft 8 and the damper rotating shaft 49 of the rotating damper 35 are positioned on the same axis.

  When the hook 3 as described above is attached to the hook casing 4, the tooth tip 33 of the rack 32 of the hook casing 4 is positioned in the tooth groove 37 of the gear 36, and the tooth groove 34 of the rack 32 is placed on the tooth tip 38 of the gear 36. Positioned so that they are meshed with each other. Therefore, when the hook 3 turns, the damper casing 46 fixed to the hook 3 rotates integrally therewith. However, since the gear 36 meshes with the rack 32, the rotation of the gear 36 is restricted, and the gear 36 And the damper casing 46 rotate relatively. Since the rotating body 48 rotates integrally with the gear 36 via the damper rotating shaft 49, the damper rotating shaft 49 rotates relative to the damper casing 46 and exhibits viscous resistance.

  A spring 43 is attached to the hook rotation shaft 8 as an urging means for urging the hook 3 toward the inside of the casing body 15. The spring 43 is supported by the shaft 40. One of the springs 43 is in contact with the hook casing 4 and the other is in contact with the inside of the hook 3. Further, a cushion rubber 44 that interferes with the collision of the hook 3 is attached to the bottom surface 18 of the casing body 15 and inside thereof.

The operation when the hanger hook 1 as described above is used will be described.
As shown in FIG. 6, when using the hanger hook 1 as described above, the pressing portion 13 of the hook 3 is pressed with a finger. The hook 3 pivots about the hook rotation shaft 8 from the upper side to the lower side in the vertical direction Y, and the arm portion 6 and the tip portion 7 protrude from the inside of the casing body 15 to the outside. By pressing the pressing portion 13 with a finger, the pressing portion 13 moves toward the inside of the casing body 15, so that the spring 43 in contact with the pressing portion 13 bends. The hook 3 is biased by the spring 43 so as to turn in the inner direction of the casing body 15.

  If the pressing of the pressing portion 13 is stopped or the clothes hooked on the hook 3 are removed, the arm portion 6 and the tip portion 7 are swung into the casing body 15 by the urging of the spring 43. That is, the hook 3 moves again so as to be stored in the hook casing 4 and returns to the state shown in FIG.

When the hook 3 moves so as to be housed in the hook casing 4 by the bias of the spring 43, the damper casing 46 of the rotary damper 35 fixed to the hook 3 rotates integrally with the hook 3. Therefore, the damper casing 46 and the rotating body 48 are relatively rotated, and the rotation operation is suppressed. That is, the turning operation of the hook 3 to which the damper casing 46 is fixed is suppressed, and the hook 3 returns to the hook casing 4 while relaxing the turning operation against the bias of the spring 43.
In this way, when the hook 3 returns to the inside of the casing main body 15, the speed becomes slow, so that the annoyance that the hook 3 returns to the inside of the casing main body 15 before applying clothes can be avoided. . Further, when the clothes hung on the hook 3 are removed, the hook 3 returns to the inside of the casing main body 15 vigorously, and the clothes etc. are prevented from being caught between the hook 3 and the casing main body 15. be able to.

  A rotation damper 35 is formed between the wall surfaces 39 at the base end portion 5 of the hook 3, and a gear 36 is formed along the damper rotation axis of the rotation damper 35. As shown in FIG. 6, the standing dimension t from the outer surface 12 of the wall surface 39 toward the inside of the casing body 15 is set to be larger than the diameter of the gear 36 at least at a position where the gear 36 is attached. Therefore, the gear 36 does not protrude from the inside of the hook 3. That is, since the gear 36 is covered with the wall surface 39 of the hook 3, the gear 36 is not exposed to the outside of the hook 3 even when the hook 3 turns. Since the gear 36 is not exposed, when the hook 3 turns, there is no concern that the garment may be caught in the gear. Therefore, the user can use the hook with peace of mind.

  In this embodiment, the gear 36 is completely covered with the wall surface 39, but a part of the gear 36 may protrude from the wall surface 39 as long as it does not cause anxiety to the user. In this embodiment, since the gear 36 does not rotate even if the hook 3 turns, even if the gear 36 protrudes from the wall surface 39, a situation in which clothes are caught in the gear 36 does not occur.

The rack 32 is formed on the protruding portion formed on the cover 16 and then the cover 16 is attached to the casing body 15, so that the rack 32 is formed as compared with the case where the rack 32 is formed directly in the casing body 15. Therefore, the manufacturing cost can be reduced.
The cover 16 is formed with a protrusion 31, and the hook casing 4 can be formed only by inserting the protrusion 31 into the insertion notch 22 of the casing body 15. Matching can be performed easily.

  In this embodiment, the spring 43 is used as the biasing means. However, the spring 43 is not limited to this type of spring, and is not necessarily limited to the spring, and other biasing means may be used. . That is, any urging means may be used as long as the hook 3 can be urged in a direction returning to the inside of the casing.
