SK109698A3 - Removable cover of an opening in a wall - Google Patents

Abstract

The covering for the aperture is inserted in a tiled wall. When the roller (7) pivots against the wall (1,2) it may be secured in a holding bearing (18). The retainer of the sprung-located roller and the strip (8) engaging in the channel (19) are adhered directly to the covering (5). The holding bearing working with the roller and the channel are formed in the wall surrounding the aperture (3).

Description

Detachable wall opening cover

Technical field

I

The invention relates to a detachable cover of an opening in a wall, for example a paneled wall, in which at least one resiliently mounted pulley is placed on one side and engages in a retaining and of the storage part.

BACKGROUND OF THE INVENTION

With the covers of this pulley effect, the force is achieved even if the sufficiently high holding pulley does not snap into the center of the holding and bearing parts accurately due to the elastic type. This is a significant advantage over other known permanent magnet housings, since even in the case of inaccurate mounting, a secure fastening is achieved.

In the known openings of openings in the paneled walls, their tiles are mounted on a plate which also carries a pulley and an opposing strip. The holding and receiving part and the groove are formed as separate parts. The known housings are therefore relatively structurally complex and therefore expensive.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a cover which, on the one hand, has the advantages of housings with resiliently mounted rollers and, on the other hand, is easier to manufacture and install.

SUMMARY OF THE INVENTION

This is accomplished by a removable cover of a wall opening, for example a paneled wall, in which at least one resiliently mounted pulley is placed on one side and, when inserted into the groove located on the opposite side and inserted into the groove on the opposite side. According to the invention, the fastening of the resilient pulley and the groove extending into the groove is carried out directly by gluing to the cover, and that the holding and receiving part cooperating with the resilient pulley and the groove are formed in the wall surrounding the opening.

In the cover according to the invention, not only is no plate necessary, but no parts are required to form the groove and the holding and receiving part. The parts required to secure the cover are fixed only to the detachable cover. When the cover is removed, no parts enter the hole.

In order to securely adhere the pulley or its bearing to the housing and furthermore to achieve a corrosion-resistant embodiment, according to a further preferred embodiment of the invention, the pulley is mounted on both sides on spring arms that protrude from a retaining piece adhered to the housing and mainly made of plastic.

In this case, the retaining part is preferably made in two parts, the part carrying the flexible arms being fixed in the means in the fastening part, which is provided with a stop edge placed across the fastening unequivocal pulley.

A simple groove formation is achieved by the thickness of the strip glued to the tile forming the cover corresponding to the thickness of the adhesive layer between the tile and the wall, the groove being formed by removing the adhesive layer in the area of the strip.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to the accompanying drawing, in which: FIG. 1 shows a side view of a cover according to the invention inserted in an opening in a paneled wall, FIG. 2 shows a side view of a retaining piece, for example made of plastic, from which spring arms supporting a pulley protrude; FIG. 5 shows a retaining part without a roller, FIG. 4 shows a fastening part pertaining to the holding part, and FIG. 5 shows a rail intended to be fastened to a cover according to the invention against a roller.

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1 is in a wall 1 which, in the illustrated embodiment, is lined with tiles

2, the aperture 3 formed. The tiles 2 are fixed to the wall 1 by means of an adhesive layer 4. The opening 3 is covered by a detachable cover 5, which is formed by one tile 6. A flexible roller 7 and a bar 8 are connected to the tile 6.

The pulley 7 is supported on both sides by plastic spring arms 9 which protrude from the holding part 10, which is mainly made of plastic. The retaining piece 10 is glued directly to the tile 6 and consists of two parts, i.e. the carrier part 11 carrying the spring arms 9 and the fastening part

12. in which the retaining piece 10 is fastened in the middle. The support part 11 is provided with projections 13 intended to be inserted into the holes 14 in the fixing part 12. After insertion of the support part 11 into the fixing part 12, the surfaces facing the tile 6 lie in one plane. so that the parts 11, 12 can be easily glued to the tile 6. To secure the position, the fastening part 12 comprises a stop edge 15.

The strip 8 also comprises a stop edge 16 whose thickness corresponds to the width of the joint between the individual tiles 2.

In order to secure the cover 5 in the opening 3 in a detachable manner, the wall 1, in the illustrated exemplary embodiment of the masonry, is slightly removed in the region of the roller 7 behind the respective tile 2, so that free space is created behind the tile 2.

17 into which the pulley 7 can lock after pivoting of the tile 6 in the direction of the arrow P. The rear edge 18 of the tile 2 then serves as a holding and receiving part of the pulley 7.

Previously, the adhesive layer 4 in the region of the strip 8 is scraped off by scraping, so that a groove 19 is required to insert the strip 8.

Many variations are possible within the scope of the invention. For example, the cover need not be a single tile 6, but may be made of several, for example four, tiles. To this end, the four tiles are joined to each other by gluing another tile to the back of the four tiles. If in this way a cover of several tiles forms, preferably two strips 8 are used, which may optionally be formed by splitting the supplied strips.

It is also possible to use a material other than plastic, for example a light metal, for the holding part 10) or for the flexible bearing of the roller 7.

The opening 3 in the wall 1 can only be formed after lining the other parts of the wall by cutting, for example by punching.

The cover 5 may also consist of a wood or metal plate, a ventilation grille or the like.
