DE820094C - Multi-turn bolt latch lock with locking eyelet - Google Patents

Description

Multi-turn bolt latch locks as locking elements on lids or doors etc. are known per se.

The previous statements cannot meet the requirements meet because they have the disadvantage that the locking nose both open as also full when the shutter is closed, d. H. on security position, pre-locked can be.

In the former case, with the lock open and fully pre-locked Bolt, when slamming, the hammer-like pressure hits the rigid, secured one Locking lug. The consequences of these closing errors, which occur very often, are that the Locking nose or the bolt cannot evade, is deformed and no longer is working. The lock has become unusable.

The subject of the invention differs from these known disadvantages in that a conscious or unconscious locking of the locking nose when open Closure by a positively controlled, the lock bolt in its snap position blocking locking element is made impossible. The bolt trap is always there in sliding position when the lock is open. The locking nose thus finds itself when slamming no rigid resistance and slides sideways. Closing errors and their consequences are excluded. The lock has unrestricted locking elements Lifespan.

The drawing represents only one of the multiple possibilities: locking , for example by means of a slide, and shows in Fig. i. the locking position with Locking piece with the lock closed, Fig. A is a side view in section, AT THE). 3 the bolt position with locking piece with the lock open, Fig. 4 one of the many guidance options of the: \ rretierstück.

The individual lock elements of a multi-turn bolt latch lock are assumed to be known.

The locking eye a, which can also be a locking hook or bolt, etc. can, presses when closing the lock on the resilient locking piece b its stop pin c and releases the recess l @ in the bolt shaft d. now only can the bolt shank d by one more turn of the key in his final locking position (strongly dotted locking nose dz, Fig. i). If you want to open the lock, the locking lug dl must be closed completely. The now only opening lock immediately gives the locking piece tensioned by the spring c b with its stop pin c free and thus locked in .der recess L the Lock bolt (Dept. 3), whereby an unconscious locking of the bolt in its final secured locking position (heavily dotted locking nose d3, Fig. 3) is impossible. The locking nose di remains in the sliding position until the lock is closed again (Dept. i), d. H. until the locking eye a the locking piece b has inevitably released for the further pre-locking of the bolt d.

Claims (1)

PATENT CLAIM: Multi-turn latch latch clip with locking eyelet, marked by a spring-loaded locking piece (b) - that when the locking parts are pressed together (Lock and locking eye) is pushed back by the locking eye (a) and a stop pin (c) carries, which is provided with a stop recess (i) of the bolt shaft (d) engages movably transversely and longitudinally to the direction of movement of the bolt, such that that when the locking parts are not in engagement with one another, the locking lug (di) is blocked against further closure and only when the Closure parts is released for this purpose.
