Description

The present invention relates to a horizontal member installed horizontally on a wall surface, for example, to protect the wall surface from impact caused by contact with a moving object or to cover and decorate a part of the wall surface. , relates to a projecting corner structure of a horizontal member installed across two wall surfaces constituting a projecting corner.

For example, in food processing facilities and distribution facilities, transportation equipment such as trolleys and forklifts are increasingly being used as the facilities become larger.
In such facilities, horizontal guarding materials are now installed at the required height of the wall to prevent damage to the wall made of, for example, insulation panels, caused by collisions with carts, etc. ing. As materials for the guard material, wood, resin shapes, metal shapes such as aluminum are generally used. Also, similar to guard materials, there are also baseboards that are installed horizontally on walls, such as baseboards that are installed at the boundary between the wall and the floor, and skirting boards that are installed at the boundary between the wall and the ceiling. (For example, see Patent Document 1 below).

In addition, at a protruding corner formed by two wall surfaces that intersect at a predetermined angle (for example, 90 degrees), horizontal materials such as the above-mentioned guard materials, baseboards, and surrounding edges are continuous so as to span both wall surfaces. It is designed to be installed.
More specifically, for example, the adjacent end faces of two horizontal members installed on two wall surfaces are cut at an angle (for example, 45°) that allows for mitering, and the inclined end faces of both horizontal members are connected to each other. It is known that the two are matched together.
Also known is a structure in which a protruding corner material made of a molded product such as resin or die-casting is interposed and fixed between adjacent end surfaces of two horizontal members (for example, see Patent Document 2 below).

A horizontal lower wall portion (24) is provided. The rear wall portion (21) has a groove portion (211) that opens rearward formed in the middle portion of its vertical width. A hanging portion (212) that extends briefly downward is formed at the upper opening edge of the groove portion (211). The angle of inclination of the upper wall portion (22) with respect to the horizontal plane is designed to be in the range of about 30 to 45 degrees, but preferably 45 degrees. With the above inclination angle, the accumulation of dust and the like on the upper surface of the upper wall portion (22) is reduced, and the width of the upper wall portion (22) does not become too large. A chamfered portion (231) is formed in the front wall portion (23) by slanting its lower edge portion downward toward the rear. In the case of the guard materials (2A) and (2B) of this embodiment, since the lower wall portion (24) is horizontal, the area of the front wall portion (23) that is likely to come into contact with a moving object such as a truck can be made relatively large, thereby increasing the protection effect of the wall surfaces (1A) (1B).
Furthermore, a horizontal upper partition wall (25) and a lower partition wall (26) are formed inside each guard material (2A) (2B). The upper partition wall (25) is provided between the upper edge of the front wall (23) and the upper edge of the bottom surface of the groove (211).
