Description

  The present invention relates to a handrail for a communication passage when connecting left and right buildings provided via joints with a communication passage.

In the conventional handrail for connecting passages, the left and right handrails are set to overlap each other by setting the left and right buildings in the left and right direction more than twice the amount of shaking.

For this reason, the size of the joint between the left and right buildings must be about three times the size of the overlapping portion of the left and right handrails, and cannot be installed. There is a disadvantage that a gap without a handrail is generated at the time of a swinging movement which becomes wide and becomes dangerous.
Patent No. 3095359

    In view of the above-mentioned conventional drawbacks, the present invention can be used safely without causing gaps even when the joints between the left and right buildings are relatively narrow, even when the left and right buildings have different large horizontal movements. An object of the present invention is to provide a handrail for a connecting passage that can absorb a swinging motion with a small joint portion without damage.

Another object of the present invention is to provide a small and compact handrail for a communication passage by absorbing the shaking motion in the front-rear direction in a small space.

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

In order to achieve the above object, according to the present invention, the front end fixed to the outer wall of the open end of one building of the part serving as a communication passage between the left and right buildings provided via the joint is the other building. A fixed handrail that protrudes in the direction to the center of the joint, a front and rear handrail that is slidably mounted in the front and rear direction on the outer wall of the opening end portion of the portion that becomes the communication passage of the other building, and the front and rear handrail A left and right handrail that slightly overlaps the front end of the fixed handrail integrally formed on the opening end side of the movable handrail formed in an L shape, and a slide attached to the fixed handrail so as to be slidable in the left and right directions Slide the handrail and the slide handrail so as to block the joint when the joint moves widely, and slide the handrail so that the slide handrail does not slide when the joint narrows. Constitutes a communication passage for handrails with the locking means engaged in the region of the tip side of the left and right handrails of the movable handrail.

Further, the present invention provides a front-rear slide handrail attached to the outer wall surface of the other building in which the front-rear handrail of the movable handrail slides in the front-rear direction so as to be slidable in the front-rear direction. The front-rear slide handrail is pulled out when swinging away from the front, and the front-rear slide handrail is locked to a position near the front end of the front-rear handrail so that the front-rear slide handrail does not slide during swinging movement where the front-rear handrail overlaps. The stop means constitutes a handrail for the communication passage.

  As is clear from the above description, the present invention has the following effects.

(1) The tip fixed to the outer wall of the open end of one building in the part that becomes the connecting passage between the left and right buildings provided through the joint is connected to the center of the joint in the other building direction. The fixed handrail that protrudes, the front and rear handrails that are attached to the outer wall of the opening end portion of the portion that becomes the communication passage of the other building so as to be slidable in the front-rear direction, and the opening end portion side of this front and rear handrail are integrated A left and right handrail that slightly overlaps the tip of the formed fixed handrail is formed in an L-shaped movable handrail, a slide handrail attached to the fixed handrail so as to be slidable in the left and right direction, and the slide handrail as a joint. The sliding handrail is slid so as to close the joint when the swinging movement becomes wide, and the sliding handrail is moved to the tip of the left and right handrails of the movable handrail so that the sliding handrail does not slide when the swinging movement becomes narrow. Because it is configured with locking means that locks to the part closer to the part, if it swings in different left and right directions, the left and right handrails of the movable handrail are moved without moving the slide handrail, and the slide handrail is moved left and right without gaps. It can be moved by the locking means as the handrail moves.
Therefore, it is possible to prevent the gap from being generated, and to prevent the slide handrail from protruding into the passage, which can be used safely.

(2) According to the above (1), by using the slide handrail, the left and right buildings are swayed by the size of the joint portion even with the fixed handrail and the left and right handrail of the movable handrail whose tip portion protrudes to the center portion of the joint portion. Can absorb.
Therefore, it can be a small and compact handrail for the communication passage.

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

(4) In the second aspect, the same effects as in the above (1) to (3) can be obtained, and the front and rear handrails of the movable handrail can be reduced by the front and rear direction slide handrail by the dimension in the front and rear direction. .
