The invention relates to a handle for the releasable covering of an opening in a wall which, when the cover is opened, projects through the joint between the wall and the cover and engages on the rear of the cover.
Covers of the type mentioned are held by magnets or resilient snaps.
The latter have the essential advantage over the mounts with permanent magnets that even with a somewhat less precise installation, a secure attachment is achieved because, due to the resilient effect of the catch, a sufficiently large holding force is achieved even if this catch does not close exactly in the center of the counter element come to lie.
It is known to use suction cups to open or release the cover. However, due to their sensitivity to dust, such vacuum cleaners are not very reliable in their effect and therefore also quite impractical to use.
It has also been proposed to design the handle as a piece of wire attached to the back of the cover. With the cover closed, this wire can be moved from a position of use protruding from the edge joint between the cover and the adjacent wall into a rest position extending within the edge joint. However, such a wire is relatively cumbersome to press into the edge joint and a pointed tool is required for removing it from the joint into the position of use, so that removal is tedious and there is also a risk of damage to the z. B. is covered with tiles or wallpaper cover.
The invention has set itself the goal of designing a handle of the type mentioned in such a way that the cover can be opened simply and securely without the risk of damaging it. is possible. This is achieved in that the part protruding through the joint between the wall and the cover has a resilient tongue. In the case of a handle according to the invention, when the tongue is pushed into the edge joint, the tongue is initially pressed back and then lies against the back of the cover, so that the cover can be pulled out of the opening by pulling on the handle.
In a particularly simple embodiment of the handle according to the invention, it is designed as a plate from which the tongue is punched out and bent out. This plate can consist of all materials that have suspension properties. It is particularly useful if the plate consists of plastic.
The invention is described in more detail below on the basis of an exemplary embodiment shown in the drawings. 1 shows the top view of the part of a tiled wall with an inserted cover, and FIG. 2 shows, on a greatly enlarged scale, a section along the line II-II in FIG. 1, the handle being pushed into the edge joint. 3 and 4 show the handle according to the invention in two mutually perpendicular views.
1, an opening --2-- is arranged in a tiled wall --1--, which can be closed by a cover --3--. In the example shown, the cover --3-consists of a plastic plate --4--, to which tiles --5-- are glued.
On the upper side of the cover --3-- is a U-shaped piece of sheet metal --6-- pushed, with which a standard snapper --7-- is screwed, which has a roller --8--, which is on arms --9-- is mounted, which can be moved inwards against the force of a spring.
Opposite the snapper --7--, a groove-shaped profile --10-- is formed on the plate --4--, which extends --4- essentially over the entire width of the plate. A ledge --11-- is attached to the underside of the opening one, which engages in the groove --12-- of the profile --10--. As can be seen from Fig. 2, the strip --11-forms the web of a T-shaped profile --13--, the flange --14-- of which is attached to the edge of the opening --2--.
To interact with the roller --8-- of the snapper --7--, a profile --15-- is attached to the upper edge of the opening --2--, the web of which --16-- is cut out in the area of the snapper-7 is.
If the opening --2-- is to be closed with the cover --3--, the latter becomes like this

Inserted diagonally into the opening so that the strip --11-- is pushed into the channel --12--. Then the cover --3-- is pivoted into the opening --2-- until the roller - in the position shown in FIG. 2 - reaches behind the elevation --18-- of the profile --15--, whereby the catch rests on a web --17-- of this profile.
To open the cover --3--, a handle is provided according to the invention, which consists of a plate --20--. This plate has a resilient tongue --21--, which is punched out of the plate and bent out. The material of the plate --20-- and especially the tongue --21-- has spring properties and is expediently plastic. But it could also be a metal plate.
If the tile is inserted into the edge joint --19-- between the cover --3-- and the tiled wall --1--, the tongue --21-- springs back for the time being and then lies against the back of the cover --3--. This state is shown in Fig. 2. It is therefore very easy to swivel the cover --3-- counterclockwise out of the opening --2-- by pulling on the plate --20--, whereby the roller --8-- slides over the elevation.
Numerous modifications are possible within the scope of the invention. Thus, the use of the handle according to the invention is not limited to covers with a snapper, but could also be used for covers held differently, for example those with magnets. Also, the handle need not be designed as a plate, it would rather be possible to fasten an insertable part with a resilient tongue to a handle.
1. Handle for the releasable covering of an opening in a wall which, when the cover is opened, projects through the joint between the wall and the cover and engages on the rear of the cover, characterized in that the through the joint (19) between the wall (1) and cover (3) projecting part has a resilient tongue (21).
