Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the structure of a hanging device for a sliding door in cases where the frontage of an office, hospital room, hallway, etc. is closed off with a pair of left and right sliding doors. It is.

[Conventional technology]

When the lintel rail that suspends and guides the sliding door is long, for example, in Japanese Utility Model Publication No. 57-55504, as a means to fix the lintel rail so that it does not bend up and down or swing from side to side, An idea has been proposed in which both end portions and the intermediate portion thereof are fixed to the frontage-side supports and the side surfaces of the studs via brackets.

[Problem that the invention attempts to solve]

If the lintel rail is made of a so-called single piece having a predetermined length, it will be bulky to transport to the assembly work site, and a large number of people will be required to perform the assembly work.

Furthermore, since the vertical deflection and left/right deflection of long lintel rails become a problem in the middle of the length, if there are no studs in the middle, the only option is to fix the transom panel directly to the transom panel. It is necessary to make it highly rigid and sturdy, and to make it a so-called strength member.

In addition, although the transom panels are usually stretched at the final stage of assembly work, when used as the strength members, they must be installed at the initial stage, making subsequent assembly work difficult. There was also a problem.

[Means for solving problems]

Therefore, in this invention, a plurality of long lintel members for movably suspending the sliding door that closes off the frontage are installed.
While being connected in a vertically bendable manner via a connecting body, the left and right ends of the lintel member are supported in a vertically adjustable manner on supports fixed to the left and right ends of the frontage, and the height of the connecting body can be adjusted. The connecting body is suspended from the ceiling via a suspension rod, and the connecting body and the ceiling are fixed by vertical and longitudinal steadying members arranged in parallel along the suspension rod. be.

[Action and effect]

According to the configuration of the present invention, when it is necessary to make the lintel member for suspending the sliding door long, it is sufficient to add one of an appropriate length via the connecting body.

The farthest end of the lintel members connected in this way is fixed in a height-adjustable manner to a support fixed to the side wall or the side of the column in the frontage, while the connecting body part in the middle of the longitudinal direction is fixed to a suspension rod. It is suspended from the ceiling via the cable. Thereby, the vertical deflection in the middle part of the longitudinal lintel member as a whole can be canceled out by the suspension support of the suspension rod.

In addition, since the height can be adjusted at the connection point between the hanging rod and the connecting body, the connected longitudinal lintel members can be made into a substantially straight line, and furthermore, the width of the frontage can be adjusted at the left and right center portions of the frontage. It can also be held in a state where it is bent in an inclined manner so that it is lower than both the left and right sides.

By arranging vertical and longitudinal steadying members in parallel with the suspension rod and fixing these steadying members to the connecting body and the ceiling, the lintel member is moved in a lateral direction substantially perpendicular to the longitudinal direction of the lintel member. It can be easily prevented from swinging.

If the ceiling part that fixes the upper end of the steady-rest member is a cap that is disposed on the ceiling surface substantially parallel to the lintel member, the cap, the lintel member, and the steady-rest member in the vertical direction that connects both A strength member with a frame structure can be constructed, and the assembly work of later tensioning the transom panels can be performed extremely easily.

Therefore, as in the case where a pair of left and right sliding doors are installed in a wide frontage such as a hospital hallway, the sliding door hanging device can be strongly constructed without requiring studs to be erected in the middle. .
