Striking plate for wooden doors or locking recess in steel frames.

The object of the innovation is a strike plate, which ensures that the lock latch is compulsory ^; frequently frictionally rests in its associated recess of the striking plate, and so the "rattling ¹ prevents the door leaf. The same measures can also be taken on the recesses of steel frames that are analogous to the strike plate. The innovation can be implemented by a peculiar shape of the strike plate or the recess in the steel frame or by an additional part made of metal or plastic.

It is known to counteract the rattling of the door leaf by special measures on the lock or on the strike plate. For example, it has been proposed that the locking surface of the trap, with the trap leading edge as the vertex, in a pointed Execute angle to the longitudinal axis. It is also known, in the recess of the strike plate or the steel tzarse crescent-shaped To arrange beads, which then have to be filed down to the required size by the craftsmen. Another known solution is to arrange an adjustable, spring-loaded member in the locking surface of the trap, that after you close the door against the inside edge the latch recess <lcs strike plate ^ or the steel frame lays. These possibilities are disadvantageous because their production is too expensive or reworking when hitting the door require, or overall insufficiently sinü.

The innovation, which can be economically manufactured and used in all its versions, is included Drawing shown in some embodiments. Show it:

Pig. 2 a section along the line II - II of the Pig. I, Pig. 3 a striking plate (partially) with a U-shaped Cross section and an object of innovation

as a molded part, in three-dimensional representation, Pig. 4 shows a section along line IV - IV of Pig. 3, Pig. 5 shows an embodiment of a molded part according to Pig. 3, Pig. 6 shows a section along the line VI-VI of Pig. 51 Pig. 7 shows a section through a frame of a door, a strike plate and a door leaf with door lock.

In a strike plate 1, for example with a right-angled cross-section (Pig. 1, 2 and 7), a recess 2 for receiving the head 3 'of the latch 3 is punched. The edge 2 'of the recess 2 facing the blocking surface 4 of the palle 3 merges into an inclined surface 5 which extends the entire dimension of the recess 2 or over a portion of the same and which forms an angle Οζ with the cover leg 1 * of the locking plate 1 of, for example, 3o °. The side of the inclined surface 5 facing the recess 2 has depressions 5 ^f , which optionally have a step-shaped or prismatic cross-section. The tip 4 'of the latch head 3' engages in one of these depressions 5 ^{1 , depending on how deep the latch head 3 1 is} due to the door clearance (dimension x) and the play that results from the overall situation of the structural unit, consisting of door leaf 2o, lock 21 (of which in Fig. 7 lock bottom 22, lock cover 22 ', lock cuff 23 and latch 3 are shown), as well as the seat of the locking plate 1 in the door frame, for example in the form of a window frame 24, can penetrate. Since the latch 3 is fixed on the one hand by its associated (not shown) guide (passage opening) in ^{the lock cuff 23 and by its tip 4 'snapped into one of the recesses 5 1} , it can result from the existing between the door leaf 2o and the door lock 21 rigid connection, the dimension y no longer change, ie the door leaf can no longer rattle ·.

The same advantageous effect is achieved if, instead of the molded - for example punched - surface 5 separate part made of metal or plastic is used, preferably of elastic nature. Figures 3 to

An exemplary embodiment is provided for this. A U-shaped baffle plate 11 also has a recess 12: the passage of the latch head 3 ¹ · This recess 12 m - for example to avoid sharp edges or to increase the strength of the strike plate - be flanged into short sliding surfaces 12 · turned to the side.

the recess 12 is a molded part 16 - for example s plastic - arranged, for example glued or jammed. The surface 15 of the molded part 16, which on its, The side facing the recess 12, depressions 15 '', for example with a stepped or prismatic cross-section f points and protrudes into the recess 12, also forms one with the handle 11 of the U-shaped strike plate 11 nkelCYof For example 3o °. How this works The procedure is analogous to that described for FIG. In addition It still seems that the elastic nature of the surface 15 promotes the desired effect by its resilient effect.
