Abstract

(57) [Summary] [Purpose] A movable handrail that eliminates the need for a movable structural member with a stopper core, can be flipped up and opened at a desired angle, does not move the handrail after flipping up, and improves productivity and cost. I will provide a. [Structure] A rotary resin shaft (8) installed so as to protrude from a bearing frame (11) and tightening frames (9) and (9 ') are rotated by a rotary tightening bolt (10).
2) A movable handrail forming (12 ').

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to a movable handrail.

[0002]

[Prior art]

 A conventional movable handrail will be described with reference to FIGS. 1 and 2 as a flip-up handrail. First, adjust the flip-up angle of the movable handrail (1) by inserting or removing the stopper core into the stopper core insertion hole (6) provided in the rotatable stopper core shaft (7) in the movable part (3). To change the flip angle. The stopper core itself is previously installed in a handrail part (5) made of a hollow material, and the stopper core is inserted and removed by a stopper core detaching lever (2) provided in a part that is easy for the user to use. It was a structure.

[0003]

[Problems to be solved by the invention]

 This had the following disadvantages. (B) The flip-up angle could only be changed by the number of set core insertion holes. (B) If the stopper was not securely inserted into the insertion hole, there was a risk that the handrail would suddenly move or fall after being flipped up. (C) There was a drawback that the handrail would not move unless the handrail was flipped up while holding the retaining core detachable lever. (D) Since a movable handrail incorporates a set-removal lever and a set-retainer, the productivity was not improved and the cost was high. The present invention has been made to eliminate these disadvantages.

[0004]

[Means to solve the problem]

 The bearing frame (11) on which the rotatable resin shaft (8) is installed is sandwiched between the fastening frames (9) and (9 '). The fastening frames (9) and (9 ') are attached to an installation surface such as a wall by a wall mounting plate (4). A rotary tightening bolt (10) penetrates through the tightening frames (9) and (9 ') and the rotary resin shaft (8). The movable portion of the present invention is flipped up and the opening angle is adjusted by the frictional force between the sliding surfaces (12) and (12 ′) formed between the movable portion and the resin shaft (8). Usually, the movement of the movable part is strengthened or weakened by tightening the rotatable tightening bolt (10).

[0005]

[Action]

 With the above configuration, it is possible to eliminate the stopper core detaching lever of the movable handrail and the stopper core itself.

[0006]

【Example】

 Hereinafter, one embodiment of the present invention will be described with reference to FIG. A through hole through which the rotatable tightening bolt (10) passes is provided in the rotatable resin shaft (8) in advance. The bearing frame (11) on which the rotatable resin shaft (8) is installed and the fastening frames (9) and (9 ') are attached by the rotatable fastening bolt (10). At this time, the rotatable resin shaft (8) has a thickness protruding outward from the bearing frame (11), and slides between the protruding portion and the tightening frames (9) and (9 '). The movable part (3) provided with the surfaces (12) and (12 '). The components, pipes, bolts, nuts, covers, plates, levers, frames, and the like that form the members of the present invention are not particularly limited as long as they are generally known. The resin used for the rotating resin shaft is preferably an acetal copolymer, MC Nylon (manufactured by Nippon Polypenco), or the like. Also, the sliding surface hardly wears in normal use, and even if worn, it can be re-tightened with the tightening bolt (10), and the movable movement is strengthened or weakened. You can adjust the handrail opening. Of course, the present invention can be used not only for a movable handrail of a flip-up type, but also for a conventional side-opening movable handrail.

[0007]

[Effect of the invention]

 Since the present invention has the above-described structure, it is possible to set a desired opening angle and opening angle regardless of the number of insertion holes of the stopper core. Further, since the handrail can be securely stopped at a desired angle, there is no danger that the handrail will suddenly fall after being flipped up. Since the operation of gripping the detachable lever is eliminated, a person with a physical disability or a caregiver can easily use it. Since there is no need for a movable structural member with a stopper, productivity can be increased and the cost can be reduced.
