Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a movable handrail which can be used as a handrail by projecting the handrail from a wall surface when necessary, and can be used as a handrail when it is not necessary and which can be used widely for a passage.

[0002]

2. Description of the Related Art A conventional handrail is fixedly attached to a wall surface by a bracket in which a handrail mount and a wall mount are integrated.

[0003]

[Problems to be Solved by the Invention] Since the conventional handrail is fixedly attached to the wall surface, when the handrail is installed in the passage of a general house for the elderly or the like, the passage becomes narrow and the passage of other people is prevented. It has the drawback that it gets in the way.

The present invention can be used as a handrail when necessary,
The purpose of the present invention is to provide a movable handrail that can be used in wide contact with the wall when it is not needed.

[0005]

In order to achieve the above object, in the present invention, a handrail mounting base for attaching a handrail,
Separately from the wall mount for mounting the handrail mount on the wall surface, a fitting portion for slidably fitting both side surfaces of the protrusion of the wall mount is provided at the lower end of the handrail mount, and the wall mount is projected. A vertical hole is provided in the center of both side surfaces of the section and an arcuate groove whose lower side is opened below the both side surfaces, and the fitting portion of the handrail mounting base is inserted into both side surfaces of the projecting portion of the wall mounting base, A support shaft for pivotally supporting the handrail mounting base on the wall surface mounting base is provided in the center of both side surfaces of the fitting portion through the long holes on both side surfaces of the projecting portion, and the wall mounting base is provided on one side below both side surfaces of the fitting portion. A tilting shaft for restricting rotation of the handrail mounting base with respect to the wall mounting base is provided through the arcuate groove, and the tilting shaft is inserted into a spring receiver protruding from the lower surface of the ceiling plate of the wall mounting base, and the lower surface of the ceiling plate and the support shaft are mounted. A movable handrail mount is provided by interposing a compression spring on the outer peripheral surface.

[0006]

[Function] The fitting portion 7 at the lower end of the handrail mount 2 is attached to the wall mount 4
Of the protrusion 5 is fitted into both side faces 6 and 6, and is supported by the center of both side faces 8 and 8 of the fitting part 7 through a long hole 9 formed in the center of the side faces 6 and 6 of the protrusion 5. The handrail mounting base 2 is pivotally supported by a shaft 10 so that the handrail mounting base 2 can be freely rotated on the wall mounting base 4, and the fitting portion 7 has a protruding portion of the wall mounting base 4 so that the handrail mounting base 2 is directly above, as shown in FIG. When pivoting to 5, the tilting shaft 12 is pivotally supported on one side below both side surfaces 8 of the fitting portion 7 through the lower left end of the arcuate groove 11 and protrudes from the lower surface of the ceiling plate 13 of the wall mount 4. The compression spring 15 is inserted into the spring receiver 14 provided, and the ceiling plate 13
Since the movable handrail mount 18 is interposed between the lower surface and the outer peripheral surface of the support shaft 10, when the handrail mount 2 is lifted together with the handrail 1 from the state where the handrail 1 is in close contact with the wall surface 3 as shown by the alternate long and short dash line in FIG. The mounting base 2 guides the support shaft 10 into the elongated holes 9 formed in both side surfaces 6 and 6 of the projecting portion 5 of the wall mounting base 4 against the elastic force of the compression spring 10 together with the fitting portion 7 at the lower end. Rise.

The tilting shaft 12 passing through the lower left end of the arcuate groove 11 of the projecting portion 5 is located at the uppermost part of the arc, and the handrail 1 is pulled toward the front side so that the tilting shaft 12 is axially supported below the fitting portion 7. The tilting shaft 12 reaches the lower right end beyond the uppermost part of the arcuate groove 11, and the handrail mount 2 keeps the descending state stable due to the elastic force of the compression spring 10. As shown in FIG. The more prominent handrail 1 is in use.

When the handrail 1 in use is further lifted up as shown by the chain double-dashed line in FIG. 2 and FIG. 5, the fitting portion 7 at the lower end of the handrail mounting base 2 rises in the same manner as described above and the right side of the arc-shaped groove 11 is increased. The tilting shaft 12 passing through the lower end is located at the uppermost part of the groove 11, and when the handrail 1 is pushed, the tilting shaft 12 is brought into close contact with the wall surface 3 as shown in FIG.
