Description

The invention relates to dnc resilient, mil one Strike cooperating case «with a Carrier who is fcdctnd to advance that one on spimtii anterior. Band-shaped end located UnIIf together with the temptation for the trap acts, and with one behind and in the same direction with the carrier arranged screw that «i mix the case and the carrier, uw de «amount of protrusion» of the role over there » Stul]> 1> hole to be set.

Hei a known trap of this kind must be Purpose of setting the amount of the outstanding of the front roll edge this first opposite older The action of a spring will prevent the the fork carrying the role lies behind the faceplate, aImLiiiii can each screw tint 180 * or a Multiples of it can be rotated. As a result, E $ cannot fine-tune it, only doe at a time Adjustment to the Hallic screw pitch.

The invention aims to provide an arrangement in which dnc fine adjustment can also be made by any desired amount. For this purpose, according to the invention, the rear end of the screw is screwed into the fixed wall of the halyard claw and at the front end forms a stop with the rear end of the carrier, which determines the amount of pricking of the roll, and the roll has a " nu by its axis extending Bobrang, which can be brought in the same direction with the axis of the screw so that the screw and thus the trap) ₀ from the outside into fine limits by means of a Schratt · is benxiehers adjustable.

dncs slidable carrier IS, the rotation of which is prevented due to the shape of the bore. At the rear end of the housing a rear wall 16 is provided, in the center of which a threaded hole 17 is made. The rear of the carrier 15 is expediently concave, as shown in FIG. *

The front part 18 of the sliding bracket 15 has a larger diameter than the nintcre TdI 39, so that dnc shoulder 20 is formed between them will. The part with the larger diameter will grow two flattened sides. It is forked, and between its two arms 21 lies dnc roller 22, the one with two gleidiacfuigcn pins attached to it23 is rotatably mounted in the arms 21. The width of the arms 21 between the flattened points is approximately equal to the diameter of the end part 19.

The non-circular opening 13 of the StutpWech takes the Roth: 22 and the Anne 21 of the carrier 15 gtcitable on. The opening is with right angled corners 24 provided, in which the arm «and the SdMi der Roll released, cm dne rotation of the carrier * 15 a prevent its own axis iu.

Per part 19 with the smaller diameter, is designed sleeve-like, and its bore 25 extends from the fork to the rear, and there the The diameter of the bore in the web 26 is smaller, an annular shoulder is formed.

In the bore of the web 26 and concentric with her is a screw 27 with a head 28 of larger diameter which slide in the bore 25 canoe, while the threaded shaft of the Screw passes through the web 26 and into the threaded hole 17 on the rear wall 16 of the housing is screwed in.

The shaft of the screw 27 also passes tightly through a nut 29 made of fiber, the shape of which corresponds to the Cross-section of the bore 13, which is therefore not rotatable and · in the event of an unintentional rotation the screw offers resistance.

In the part 19, a spring 30 is arranged between the front surface of the fiber nut 29 and the Shoulder 20 acts and pushes carrier 15 out of the housing as far as screw head 28 does allows.

The head 28 of the screw lies behind the roller 22 and is provided with a screwdriver slot 31 od strand a hole arranged along a diameter, through which a screwdriver or a similar tool can be inserted and inserted into the slot on the head 28 of the screw with a suitable setting of the roller. The bore 32 in the roller is preferably circular and is m DER center, and as shown in Fig of the circumference of the roll can. 1 and 3, be full. Of course, the roller can also be provided with a central, annular groove 33 into which the bore 32 opens. The result is that the edge of the bore cannot be damaged so severely by the strike plate during the movements of the roller that the insertion of a tool could be prevented. The annular groove 33 can have any cross-section.

As already stated, the roller 22 is provided with two identical pins which are inserted into the arms 21 be rotated, and in order to keep the pins in the roller, they are driven into the roller so far that that its inner end protrudes a small amount into the bore 32 of the roller. Then the Pins set by suitable tools, e.g. B. in that a mandrel or the like. Through the bore 32 driven through and the protruding ends are spread or riveted.

To enable easy cleaning of the trap or replacement of the individual parts, the The screw z / is unscrewed and taken out of the housing with the bolt and the compression spring will. The carrier 15 is expediently without the rollers and pins, as is the body 10

S made from injection molding.

After attaching the trap to a door, the amount by which the roller 22 moves across the front surface of the faceplate protrudes. After rotating the roller in a position in which the bore 32

xo is in the same direction as the screw head 28, a screwdriver is used and the screw rotated in one direction or the other so that the screw head of the front surface of the faceplate approaches or away from it and the amount of protrusion of the role changed accordingly will. A fine adjustment can therefore be made without removing the latch from the door needs to become.
