Plastic switch rosettes

So-called rosettes are used to attach switches to the plaster Made of wood or cardboard, which in turn is used on the wall either be fastened with a dowel or steel needles. They have the disadvantage that they can be used on wet plaster or in damp rooms soon to be unusable

The subject matter of the invention is to be made of a material that is resistant to all corrosion influences, which at the same time tough, impact-resistant, screwable and «nailable and available in any color». An ideally suited plastic is used for this into consideration

Such rosettes are usually attached in two ways, and either with an expansion dowel (Fig. 5) or with steel needles (Fig # 4, 13) »therefore the execution is also different, for example after Fig. 1 for dowels ~ and Fig. 2 for needle attachment · The dowel sets a small medium (2) in front, the steel needle (13) a larger one Number of edge holes (5)> which can be countersunk at the same time to to pick up the nail head

The switch line is introduced in one case through the edge recess (6), in the other through a larger one Center hole (7) · Otherwise both types are in the external dimensions of the same size, so that they can also come out of one tool, only with interchangeable inserts · You can use a reinforcement edge (14) and also have reinforced holes. The holes (3) for screws should be in such a way that a screw has its thread himself cuts · The nail holes (5) should e.g. be designed with a thin-walled constriction so that all needles, nails etc. only hold by fingex ^ pressure (cannot be lost) and without can still be held with the fingers, can easily be driven in with a hammer

The spreader plug shown in Fig.5 with an elastic slit sleeve (9) made of steel or plastic, drive nut (11) and clamping screw (#) can of course also be made with a plastic or fiber dowel be replaced with a spreading hola screw, as usual «

A special design provides for the rosette (1) at the same time the dowel Ö2) from a single cast, as shown in Fig. 6, where instead of the otherwise usual expansion screw, an expansion wedge (15) is shown, which is also made of plastic like the rosette (1) and the dowel (12) may exist. It can even be connected to the rosette or the dowel, but can easily be torn off, in one operation pressed, spread or otherwise suitably manufactured.

Claims (1)

Claim 1 Switch rosette »characterized by» that it consists of corrosion-resistant, tough »impact-resistant plastic in various colors · Claim 2 claim Switch * rosette according to claim 1 »characterized in that it has any cable entry on the hand (6) or in the middle (7) it is also provided with any central dowel (Fig. 5 or 6) or fastened or glued on with steel pins (13). Switch * Eosette according to claim 1 and 2, characterized in that the kibel (12) and a drive wedge (15) can be torn off »connected to the rosette, can be produced from a single cast. Claim 4- Switch - Eosette marked according to claims 1-5 * in that 2 screw holes (3) are formed at a standardized distance from each other in this way are that screws cut their own thread when in use * claim 5 Switch - socket according to claims 1-5 »marked by arranging a number of hail holes (5) on the hands »which are shaped in this way» that they can e.g. * steel needles (13) »only with finger pressure applied »hold» to then be struck in without further approaching the fingers *
