Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail provided at joints of left and right buildings built through joints.

[0002]

2. Description of the Related Art Conventionally, a handrail of this type has a structure in which a handrail bar can be slid to expand and contract so as not to be damaged when a building on the left and right shakes due to an earthquake or the like.

[0003]

However, the conventional handrail using the extendable handrail bar has a drawback that it cannot be extended or contracted smoothly due to rusting of the extendable portion of the handrail bar after installation for a long time, resulting in damage. At the same time, there is a drawback that it can only be set to an amount of expansion and contraction that is about half the size of the joint, and it cannot be used for buildings such as seismic isolated buildings where the amount of movement is large.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
The purpose of the present invention is to provide a handrail with a simple structure that operates smoothly even after being installed for a long period of time, and that does not follow damage even if a large shaking motion is caused.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are only for explanation and do not limit the technical scope of the present invention.

[0006]

In order to achieve the above object, the present invention provides a pair of rotatably attached to a floor skeleton on the open side surface side of a joint portion of left and right buildings built via a joint portion. And a plurality of pairs of handrail bars whose rear end portions are fixed at predetermined intervals so as to correspond to the pair of pillars, respectively, and a lower portion that rotatably supports the tip portions of the plurality of pairs of handrail bars. A handrail is constituted by a movable support pillar slidably supported by a joint plate covering a floor portion of the joint portion.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the embodiments shown in the drawings.

20 and a mounting cap 21 that is screwed and fixed to the upper part of the movable column main body 19.

In the handrail 1 having the above structure, when the left and right buildings 3 and 3 are shaken due to an earthquake or the like and the joint portion 2 is narrowed, as shown in FIG. The three pairs of handrail bars 5, 5, 5, 5, 5, 5 and 5 rotate so that the movable support column 8 projects inward, and absorb the shaking motion.

When the joint portion 2 swings so as to become wider, the pair of support columns 4 and 4 rotate as shown in FIG. 7, and the three pairs of handrails move the movable support column 8 outward. The bars 5, 5, 5, 5, 5, 5 rotate to absorb the shaking motion.

When the left and right buildings 3 and 3 swing in different front and rear directions, the pair of columns 4 and 4 rotate as shown in FIG. 8 and the movable column 8 rotates in the left and right directions. The three pairs of handrail bars 5, 5, 5, 5, 5, 5 rotate to absorb the shaking motion. In this case, even when the joint portion 2 is narrowed or widened, the swaying motion can be similarly absorbed.

A plurality of pairs of handrail bars whose rear end portions are fixed at predetermined intervals, and a lower portion that rotatably supports the front end portions of the plurality of pairs of handrail bars are slidably movable to a joint plate that covers the floor portion of the joint portion. As it is composed of supported movable columns, even if the joints of the left and right buildings are narrowed or widened due to an earthquake, etc., even if they swing in different front-back directions, a pair of columns and multiple pairs of handrail bars will rotate. It can move and absorb the shaking. Therefore, even if it is used for a long period of time, the pair of columns and the plurality of pairs of handrail bars can be rotated, and the damage can be efficiently prevented.

(2) According to the above (1), since the tip ends of the plurality of pairs of handrail bars are rotatably supported by the movable support columns, it is possible to follow the expansion and contraction movement corresponding to the size of the joint portion. . Therefore, it can be sufficiently used for a seismic isolated building or the like which has a large movement amount.

(3) According to the above (1), since the structure is simple, it can be installed easily.

(4) Claims 2, 3, 4, and 5 also have the above (1).
The same effect as (3) is obtained.
