DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail whose overhang from a wall surface can be adjusted in a plurality of steps.

[0002]

2. Description of the Related Art Conventionally, handrails are provided on stairs and inclined passages of buildings and the like in order to ensure the safety of pedestrians. Most of the above handrails are fixed to the wall with brackets, but recently, when not in use or in the way, they are stored close to the wall and can be extended to a position away from the wall when in use A handrail has been proposed.

[0003]

However, since the conventional handrail has a complicated structure, the number of parts is increased, so that a lot of trouble is required for assembling, and there are problems such as a high price. SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and has as its object to provide a handrail having a simple structure and easy to assemble at a low cost.

[0004]

According to the present invention, in order to achieve the above object, a movable bracket is pivotally attached to a fixed bracket fixed to a wall surface by a fixing tool with a pin, and the fixed bracket is attached to the fixed bracket. A guide groove is provided for locking the locking rod inserted into the elongated hole of the movable bracket at the use position and the storage position, and a handrail body is attached to the handrail mounting plate of the movable bracket.

[0005]

According to the above construction, the handrail attached to the wall can be easily moved into and out of the use position and the storage position by moving the locking rod.

[0006]

An embodiment of the present invention will be described in detail with reference to the drawings. In the figure, reference numeral 1 denotes a handrail main body made of a pipe or the like, and 2 denotes a bracket for fixing the handrail main body 1 to a wall surface 3.

As shown in FIGS. 1 to 4, the bracket 2 comprises a substantially U-shaped fixed bracket 2a and a movable bracket 2c which is rotatably pivoted to the fixed bracket 2a by a pin 2b. Bracket 2a
Is fixed to the wall surface 3 by the fixing tool 4.

[0008] The fixing bracket 2a has a pin 2
(b) Guide grooves 2d having an inverted concave shape are formed on both side surfaces above, and both ends of a locking rod 2f provided so as to pass through the elongated hole 2e of the movable bracket 2c are fitted into these guide grooves 2d. Guide grooves 2d at both ends of the locking rod 2f.
A knob 2g for moving the locking rod 2f along is provided.

The movable bracket 2c comprises a substantially trapezoidal side plate 2h and a handrail mounting plate 2i for connecting the two side plates 2h. A handrail body is provided at the upper end of the handrail mounting plate 2i. 1, and can be rotated about the pin 2b in the range of the use position shown by the solid line in FIG. 1 and the storage position shown by the imaginary line in FIG. In the drawing, reference numeral 2j denotes a reinforcing rib extruded to reinforce the neck of the handrail mounting plate 2i.

Next, when the handrail body 1 is mounted on the wall surface 3, first, a plurality of brackets 2 are fixed to appropriate portions of the wall surface 3 by the fasteners 4. In fixing the bracket 2, as shown in FIG. 1, the bracket 2 is easily attached by inserting the bolt hole 2k of the fixing bracket 2a into the fixing tool 4 previously planted on the wall surface 3 and tightening the nut 4a.

When a predetermined number of brackets 2 are fixed to the wall 3, the handrail body 1 may be mounted on the handrail mounting plate 2i of the movable bracket 2c as shown in FIG. 1, and the handrail body 1 is stretched to the use position. In the case of the handrail, the both ends of the locking rod 2f are lifted along the elongated hole 2e of the movable bracket 2c, and are moved to the outer end of the guide groove 2d to be locked to the outer end of the guide groove 2d. The main body 1 can be fixed at the use position.

When not in use, the locking rod 2f is moved to the inner end of the guide groove 2d by the same operation as when used, and is locked to the inner end of the guide groove 2d, so that the obstruction along the wall surface 3 is prevented. Can be stored in a location that does not

[0013]

As described in detail above, according to the present invention, the handrail main body can be attached to the wall only by fixing a bracket having a simple structure consisting of the fixed bracket and the movable bracket at an appropriate position on the wall. Since the structure is simpler than the conventional one, the number of parts can be significantly reduced,
Since the assembling work is also easy, it can be provided at low cost.
