Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a decorative edge of a board attached to a wall surface such as a blackboard, whiteboard, bulletin board, etc.

(Prior art) Conventionally, this type of board has had a frame made of aluminum alloy or wood around the periphery, and when installing it on a wall, attach mounting brackets made of angle material or the like to predetermined positions above and below the wall. It is common practice to fix the frontwardly projecting mounting pieces of these mounting brackets to the upper and lower ends of the board by passing through the edge frame and fixing them with screws.

(Problems to be Solved by the Invention) However, the above-mentioned conventional mounting structure has a drawback in that the heads of the mounting bracket and screws are exposed to the outside, resulting in a very poor appearance. Therefore, attempts have been made to hide the screw heads by bending the mounting piece of the mounting bracket into a U-shape or the like, but this inevitably results in poor appearance due to the exposed mounting bracket. On the other hand, even when the frame is configured to be screwed to the board, there has conventionally been a problem in that the screwed portions are visible from the outside, resulting in poor appearance.

In view of the above-mentioned circumstances, the present invention provides a decorative edge that can improve the external appearance of the board without exposing the mounting brackets, screw fixing parts, etc. to the outside, and that does not interfere with the installation of the board on the wall surface. The purpose is to

(Means for Solving the Problems) In order to achieve the above object, the decorative edge of the wall-mounted board according to the present invention has a frame body made of a hard or semi-hard material, and a band-like edge made of a soft material. The edge frame main body includes a decorative front wall portion that covers the front side of the edge of the wall-mounted board, a mounting wall portion that extends rearward from the front wall portion and covers the edge surface of the board; It has a cover mounting convex part that protrudes outward in the surface direction of the board so as to form a substantially T-shaped cross section together with the front wall part and the mounting wall part, and this convex part has a stepped part on the rear side of the top thereof. The cover is integrated with the edge frame main body by fitting one edge of the cover into the step of the convex portion and adhering thereto, and is disposed to cover the mounting wall, and is arranged to cover the mounting wall, and A flexible sheet is attached from the outer surface of the cover to the outer surface of the cover.

(Function) Since the strip cover is made of a soft material, when attaching it to the wall of the board and attaching the decorative edge itself to the marking plate, the cover must be flipped up from the state where it covers the mounting wall of the edge frame body. The mounting wall can be deformed to a state where the outer surface thereof is exposed.
Therefore, with this cover turned up, the mounting piece of the mounting bracket is inserted into the space formed between the mounting wall part and the cover mounting convex part, and the mounting piece is attached to the mounting wall part. The work of fixing screws to the edge surface of the intervening board, or the pressing work until curing when adhering the mounting wall part to the edge surface of the board with adhesive without using the mounting hardware, etc.
This can be done without any problems. Therefore, when the cover is returned to its original state after these attachments are completed, the mounting piece of the mounting bracket and the screw fixing portion of the edge frame body are covered by the cover and are not exposed to the outside. Further, the joint portion of the frame main body with the cover is completely hidden by a flexible sheet covering the outer surface.
