In, the bracket 32 can be easily and quickly removed from the base 12 by merely loosening the small screw 48 with a screwdriver and pulling the bracket 32 away from the base 12. In addition, since the upper projection 40 of the bracket 32 engages with the upper projection 22 of the base 12 and the lower projection 42 is disposed in the projection insertion recess 20 of the base 12, the bracket 32 has small screws. Since the load is hardly applied to the small screw 48, the small screw 48 can be easily loosened with a screwdriver. For this reason, the bracket 32 can be easily and quickly removed as compared with the conventional case in which a spanner wrench of a tool is prepared and a bolt tightened by the spanner wrench is loosened to remove the bracket. Thus, the bracket 32 provided with the handrail portion 58 protruding from the wall surface 14 can be removed, so that the stairs can be widely used when carrying furniture or the like on the stairs. After the bracket 32 is removed, the base 12 is fixed to the wall surface 14, but the hexagonal bolt 16 does not protrude, so that it is not dangerous and the appearance does not deteriorate. In addition, even after the bracket 32 is removed, the small screw 48 is not integrated with the bracket 32 and does not fall apart, so that the small screw 48 can be prevented from being lost and the small screw 48 is attached to the bracket 32 even when the bracket 32 is attached to the base 12 again. Since they are integrated, the small screws 48 need only be tightened with a screwdriver as they are, so that the mounting workability is good. Next, when attaching the removed bracket 32 to the wall surface 14 again, the base 12 attached to the wall surface 14 is held by the bracket 32 so that the base end 34 of the bracket 32 corresponds to the base insertion of the base end 34. The base 12 is inserted into the recess 38, and the upper protrusion 40 of the bracket 32 is engaged with the upper protrusion 22 of the base 12, and the lower protrusion 42 of the bracket 32 is inserted into the locking piece insertion recess 20 of the base 12. Let it. Then, the small screw 48 screwed into the screw hole 46 of the bracket 32 is tightened with a screwdriver, and the small screw 4
8 is screwed into the screw hole 50 of the base 12 so that the bracket 32 is securely connected to the base 1.
2, the bracket 32 can be easily and quickly attached to the base 12. Therefore, in the detachable handrail 10 of the present invention, if a screwdriver is prepared and the small screw 48 is tightened, the bracket 32 can be easily and quickly attached to the base 12, so that a conventional spanner wrench is prepared and strong. The attaching work of the detachable handrail 10 can be easily performed as compared with the case where the bolt is strongly tightened by force. Further, if the detachable handrail 10 of the present invention can be easily and quickly attached to and detached from the wall surface 14, the stairs can be made with a minimum width, so that the size of the room in the house can be increased. There is.
The width of the base fitting recess 38 of the bracket 32 is larger than the width W of the base 12 (see FIG. 5).
2 can be slid slightly left and right. For this reason, as shown in FIG. 6, when attaching and detaching the handrail 10 so that the handrail portion 58 is bent over the corridor and the stairs, the bracket 32 can be attached and detached even if the bracket 32 is attached in the vertical state and the inclined state. This makes it possible to increase the width of the place where the detachable handrail 10 can be attached.

In the embodiment, the case where the detachable handrail 10 is mounted on the wall surface 14 corresponding to the stairs is shown, but it is needless to say that the handrail 10 may be mounted on the wall surface which does not correspond to the stairs such as a wall in a corridor. It is.
