When the large diameter portion 24 moves a little, the upper end 24b of the large diameter portion 24 collides with the side surface of the top plate side boundary protruding wall 56 (FIG. 10 (c)), but the side surface is gently inclined. The portion 24b can proceed obliquely downward along the side surface, and can smoothly ride over the top plate side boundary protruding wall 56 (FIG. 11A). Then, it passes through the space at the boundary and enters the second large diameter chamber 34. At this time, the small diameter portion 22 can move smoothly through the small diameter portion guide hole 40.

  When the large diameter portion 24 enters the second large diameter portion storage chamber 34, the upper end portion 24b is locked to the second top plate side peripheral portion protruding wall 60 and can not move any more (Fig. 11 (b) Then, the operation of moving the large diameter portion 24 downward is performed. Then, the lower surface 24a of the large diameter portion 24 is locked to the peripheral edge portion 34a (1) of the upper surface of the bottom plate 34a, and the shaft 14 is held in a state where the small diameter portion 22 protrudes outward from the hanging hole 38 (FIG. 11). (C)).

  Thus, the operation of attaching the shaft 14 to the receiving tool 12 is completed, and the clothespin M or the like can be suspended from the shaft 14 as shown in FIG. 1.

  When the user removes the shaft 14 from the receiving tool 12, first, the shaft 14 is pushed up to perform an operation of moving the large diameter portion 24 upward. By this operation, the upper end portion 24b of the large diameter portion 24 enters the inside surrounded by the top plate 34c, the top plate side boundary portion protruding wall 56, and the second top plate side peripheral portion protruding wall 60 and is locked. (Fig. 12 (a)).

  Next, an operation of moving the large diameter portion 24 toward the first large diameter portion accommodation chamber 32 in the diameter direction is performed. When the large diameter portion 24 moves a little, the upper end portion 24b of the large diameter portion 24 collides with the side surface of the top plate side boundary portion protruding wall 56 and is locked (FIG. 12 (b)). Since this side has a steep slope, and the upper end 24b can not easily get over the top plate side boundary protruding wall 56, the user moves the large diameter portion 24 slightly downward, Move in the direction of the first large diameter chamber 32 (FIG. 12 (c). By this operation, the large diameter portion 24 passes through the space of the boundary portion and enters the first large diameter chamber 32. In addition, the small diameter portion 22 can move smoothly through the small diameter portion guide hole 40.

  When the large diameter portion 24 enters the first large diameter portion storage chamber 34, the upper end portion 24b is locked to the first top plate side peripheral portion protruding wall 58 and can not move any more (FIG. 13A) Next, the large diameter portion 24 is moved downward, and the large diameter portion 24 is pulled out from the insertion opening 36 (FIG. 13 (b). Then, the shaft 14 is removed from the receiving tool 12). Can.

  As described above, the hanging device 10 is simpler in structure, easier to make than the hanging device of Patent Document 1, and is excellent in durability.

  In addition, the hanging device 10 is characterized in that it does not easily come off the receiving tool 12 even if an unexpected force is applied to the shaft 14 during use. In order for the shaft 14 to drop out of the receptacle 12, the large diameter portion 24 in the second large diameter portion accommodation chamber 34 must move to the first large diameter portion accommodation chamber 32. However, at the boundary between the two large diameter storage chambers 32 and 34, there are the top plate side boundary convex wall 56 and the pair of bottom plate side boundary convex walls 42, and the space of the boundary is very narrow. . Further, since the inclination angle of the side surface of the top plate side boundary portion protruding wall 56 on the side of the second large diameter portion accommodation chamber 34 is steep, the upper end portion 24 b of the large diameter portion 24 is easily caught. Furthermore, the upper end portion 24b of the large diameter portion 24 is easily caught on the peripheral portion of the slit-like through hole 66 provided with the top plate 34c of the second large diameter portion accommodation chamber 34. Therefore, the large diameter portion 24 can not easily pass through the boundary space.

  On the other hand, if the user performs an easy operation correctly, the shaft 14 can be attached and detached smoothly. For example, since the first large diameter portion accommodation chamber 32 and the insertion port 36 of the receiving tool 12 are set large with allowance for the size of the large diameter portion 24 of the shaft 14, the large diameter portion 24 can be easily made. It can be inserted. However, when the first large diameter portion accommodation chamber 32 is large, it becomes an issue to properly guide the large diameter portion 24 toward the space of the boundary portion, but the large diameter portion 24 is accommodated in the first large diameter portion accommodation room. When deeply inserted into the chamber 32, the upper end portion 24b enters the inside surrounded by the top plate 32c, the top plate side boundary protruding wall 56 and the first top plate side peripheral protruding wall 58, and is positioned at an appropriate position Therefore, if the large diameter portion 24 is moved in the direction of the second large diameter portion accommodation chamber 34, the large diameter portion 24 is naturally guided toward the space of the boundary portion. Further, since the inclination angle of the side surface of the top plate side boundary portion protruding wall 56 that works to prevent falling off is gentle on the first large diameter portion accommodation chamber 32 side, the upper end portion 24b of the large diameter portion 24 is along this side surface. And can go over the top board side boundary protruding wall 56 smoothly. Therefore, the large diameter portion 24 can be smoothly moved to the second large diameter portion accommodation chamber 34, and the shaft 14 can be easily attached.

  Similarly, when the large diameter portion 24 in the second large diameter portion accommodation chamber 34 is moved upward when removing the shaft 14, the upper end portion 24 b is moved to the top plate 32 c, the top plate side boundary portion protruding wall 56 and the Since it enters inside surrounded by the two top board side peripheral part protruding walls 60 and is positioned at an appropriate position, an operation to move the large diameter part 24 in the direction of the first large diameter part accommodation chamber 32 is performed For example, the large diameter portion 24 is naturally induced in the direction of the space of the boundary portion. When the shaft 14 is removed, the upper end portion 24a of the large diameter portion 24 is easily caught by the top plate side boundary portion protruding wall 56, so the large diameter portion 24 is moved slightly downward before the first large diameter portion accommodation. Although it is necessary to move in the direction of the chamber 32, it is an easy operation for the user. Therefore, the large diameter portion 24 can be smoothly moved to the first large diameter portion accommodation chamber 32, and the shaft 14 can be easily removed.

  The shaft's anti-falling property and ease of attachment / detachment (the user's feeling of attachment / detachment smooth) are mutually contradictory characteristics. However, the hanging device 10 can set opposite characteristics in a well-balanced manner, and the sizes of the first and second large diameter portion accommodation chambers 32 and 34 which the receiving tool 12 has, the top plate side boundary Height and inclination angle of the side projection 56, layout of the first and second top panel side peripheral projection 58 and 60, inclination angle of the inner side, height of the pair of bottom panel side projection 42 and the like Fall-off prevention and ease of removal by changing the shape of the head 20 of the shaft 14 or changing the shape etc. of the large-diameter portion 24 of the head 20 of the shaft 14 Can be finely adjusted.

  In addition, in the hanging device 10, the lower surface 24a of the large diameter portion 24 of the head 20 bulges downward, and the peripheral portion 34a (1) of the bottom plate 34a of the second large diameter portion accommodating portion 34 is recessed downward The bottom plate 34a can hold the head 20 stably because the structure is in contact. In particular, if the sliding contact surfaces are formed in an arc shape, the large diameter portion 24 is stably held even if the shaft 14 is slightly inclined, so that the lower surface of the mounted body can be used without any problem be able to. .

  In addition, the hanging apparatus of this invention is not limited to the said embodiment. For example, in the case of the hanging device 10 described above, the top plate side boundary protruding wall 56 of the holder 12 is the second large diameter portion accommodation chamber with the inclination angle of the side surface on the first large diameter portion accommodation chamber 32 side. It is set looser than the inclination angle of the side on the 34 side to improve the shaft's drop prevention and ease of removal in a well-balanced manner. However, the setting of the inclination angle can be changed as appropriate as long as a desired fall-off prevention property and ease of attachment and detachment of the shaft can be obtained.

  The above-mentioned receptacle 12 is provided with the first top plate side peripheral part protruding wall 58 on the top plate 32c of the first large diameter part accommodation chamber 32, and the upper end 24b of the inserted large diameter part 24 is appropriately positioned. The first top-plate-side protruding wall 58 may be omitted if necessary. The same applies to the second top-plate-side peripheral edge protruding wall 60 of the top plate 34 c of the second large-diameter portion accommodation chamber 34.

  Although the above-mentioned receptacle 12 makes metal base member 26 in order to secure high rigidity, if predetermined rigidity is obtained, the material of base member is changed to other materials (hard synthetic resin etc.) May be Further, although the top plate member 28 and the auxiliary cover 30 are formed of a relatively flexible synthetic resin, they can be easily attached to the base member 26 utilizing the flexibility of the engagement claws 28b and 30b. For example, the material may be changed to metal and screwed to the base member. Further, since the auxiliary cover 30 mainly works to adjust the appearance of the receiving tool 12, it may be omitted if necessary.

  Although the above-mentioned shaft 14 is a structure suitable for hanging the clothesliner M, the structure other than the head 20 can be freely changed in accordance with the hanging item.
