First, the guide member 52 and the helical spring 60 are set on the flat portion 48 of one arm locking member 24, and the pair of arm locking members 24 are attached to the case member 18. The arm member 62 may be inserted in advance before assembling, or may be inserted into the case member 18 before attaching the arm locking member 24 or the lower cap 22.
[0019]
After the rail member 14 is attached to the building 12, for example, a wall surface of a condominium or a handrail of a veranda with a bolt 16, a case member 18 is attached to the rail member 14 so as to be slidable. Further, the rail member 14 may be attached to the building 12 after the assembled case member 18, the lower cap 22, and the arm locking member 24 are slidably attached to the rail member 14 in advance.
[0020]
Next, an operation of changing the arm member 62 from the housed state to the used state in the drying apparatus 10 of this embodiment will be described. FIG. 1 shows a housed state in which the arm member 62 is housed inside the case member 18. The mounting portion 68 and the shaft portion 70 of the arm member 62 abut against the stopper 21 mounted on the guide groove 20 of the case member 18 and are housed at predetermined positions. The distal end of the arm member 62 on the side opposite to the mounting portion 68 projects to a length such that one rod receiving portion 66 is exposed from the arm locking member 24. Therefore, the clothesline 80 can be stored in a state where the clothespin 80 is inserted into the exposed rod receiving portion 66.
[0021]
Next, when the arm member 62 is pulled out and put into use, as shown in FIG. 4, the arm member 62 is pulled up vertically upward, and the shaft portion 70 of the mounting portion 68 of the arm member 62 is moved to the guide groove 20 of the case member 18. To the guide groove 44 of the arm locking member 24 as shown in FIG. At this time, the flat surface 71 of the shaft portion 70 of the arm member 62 slides into the guide grooves 20 and 44, and the arm member 62 is stably pulled up. When the arm member 62 is further pulled upward, the shaft portion 70 of the mounting portion 68 of the arm member 62 comes into contact with the helical spring 60 as shown in FIG. It moves away from the lower end 58 a of the groove 58 and moves toward the upper end 58 b of the groove 58 as the arm member 62 rises. Then, the shaft portion 70 of the mounting portion 68 of the arm member 62 changes its moving direction at the bent portion 44a of the guide groove 44, and moves toward the distal end portion 45 of the groove portion 44 as shown in FIG. At this time, the elastic force of the helical spring 60 acts on the shaft portion 70, and the arm member 62 is urged toward the distal end portion 45 of the guide groove 44, and easily moves to the distal end portion 45.
[0022]
Thereafter, the arm member 62 is locked to the arm locking member 24. The locking operation is performed when the shaft 70 of the arm member 62 comes into contact with the front end 45 of the guide groove 44 while holding the angle of the arm member 62 obliquely upward, as shown in FIG. 72 is located in the concave portion 40 of the engaging portion 36 of the arm locking member 24, and the locking surface 72b of the engaging projection 72 and the locking surface 42 of the engaging portion 36 abut. Further, the locking surface 74b of the engaging projection 74 contacts the locking surface 38 of the engaging portion 36. Thus, the arm member 62 is held obliquely upward by its own weight. When the arm 62 is housed in the case member 18, the procedure is the reverse of the above operation.
[0023]
Next, when the angle of the arm member 62 is changed from diagonally upward to horizontal, the arm member 62 is slightly pulled upward diagonally upward as shown in FIG. It is moved away toward the bent portion 44a. Thereby, the engagement projections 72 and 74 are separated from the engagement portion 36 of the arm locking member 24, and the engagement is released. Then, the arm member 62 is rotated about the shaft portion 70 to be horizontal. The rear shaft 70 is moved to the front end 45 of the guide groove 44.

Abuts. Then, the locking surface 76b of the engaging projection 76 contacts the locking surface 38 of the engaging portion 36. Thus, the arm member 62 is held horizontally by its own weight.
[0024]
When changing the angle of the arm 62 from horizontal to obliquely upward, when a force is applied to raise the arm member 62 upward, the locking surfaces 74b, 76b of the engagement protrusions 74, 76 of the arm member 62 cause the arm locking. The contact surface 72c of the engagement projection 72 is separated from the locking surfaces 42 and 38 of the engagement portion 36 of the member 24, and the abutment surface 74c of the engagement projection 74 is engaged with the upper end 36a of the engagement portion 36. It contacts the edge 36b of the recess 40 of the joint 36. When the arm member 62 is further rotated, the arm member 62 is pushed up by the engagement projections 72 and 74 of the arm member 62, and is pushed up obliquely upward. When the arm member 62 is further lifted, the tops 72a, 74a of the engagement projections 74, 76 pass through the upper end 36a of the engagement portion 36 and the edge 36b of the recess 40, and the shaft 70 It returns to the front-end | tip part 45. Then, the lifting force of the arm member 62 is released, and the locking surfaces 72b, 74b of the engaging protrusions 72, 74 abut against the locking surfaces 42, 38 of the engaging portion 36 of the arm locking member 24 from below. The arm member 62 is held in a diagonally upward direction.
[0025]
The operation of changing the angle of the arm member 62 is performed by raising and lowering the clothes rod 80 while hanging the clothes rod 80 over the pair of arms 62. Can be simultaneously engaged with and released from the engaging portion 36 of the arm locking member 24, and the position can be changed.
[0026]
When changing the height of the arm member 62, the case member 18 is slid up and down along the rail member 14.
[0027]
According to the drying apparatus 10 of this embodiment, the laundry can be reliably held with a simple structure. Particularly, in the operation of locking the arm member 62 to the arm locking member 24, the shaft 70 is automatically biased toward the distal end 45 of the guide groove 44 by the helical spring 60, so that the shaft 70 is automatically guided. It moves to the tip end side of the groove 44. Then, a force is applied to the arm member 62 downward by the weight of the rod 80 or the laundry, and the shaft portion 70 of the mounting portion 68 of the arm member 62 is attached to the distal end portion 45 of the guide groove 44 of the arm locking member 24. The arm abuts from above, and two of the engagement protrusions 72, 74, and 76 of the arm member 62 abut against the locking surfaces 42, 38 of the engagement portion 36 of the arm locking member 24 from below. The member 62 is firmly and reliably held by the arm locking member 24.
[0028]
When changing the angle of the arm member 62, the engagement between the arm member 62 and the arm locking member 24 is released by a simple operation of merely lifting the arm member 62 obliquely upward from the arm locking member 24. , Can be manually rotated in any direction, and the operability is good. In particular, when the angle of the arm member 62 is changed upward, it can be performed by a simple operation of merely rotating the arm member 62 upward. Then, in a state where the clothesline 80 is passed over the pair of arm members 62, the engagement of the pair of arm members 62 can be simultaneously released by lifting or lowering the clothesline 2, and the angle can be changed. The angle of the arm member 62 can be adjusted according to the angle of sunlight or the weather while the laundry is being dried. When not used, the arm member 62 can be housed in the case member 18. The height of the arm member 62 can be easily changed by sliding the case member 18 up and down along the rail member 14.
