Definitions
- the invention relates to a lock against the pushing back an ejected bolt or the latch actuated Push rod with a release device in the kinematic Connection between a bolt and a drive, e.g. between a bolt-side push rod and a drive-side Push rod and with a spring-biased non-locking latching pawl, wherein at Retraction actuation of the drive and stoppage of the return blocked Riegel or the bolt-side push rod a Control surface in the connection to the drive, in particular to the drive-side push rod, for example by emergence on a ramp surface of the pawl, this from the Lock position lifts.
- Push rod drives for locks and the like must be prevented by applying force to the bolt or on the bolt-actuating push rod or a Connection slide, this can be pushed back.
- the drive should be so constructed in a multi-bolt lock be that unlocking only with the lock mechanism Help the key or pusher, but not through external force can occur. Still, it is, in particular with very small lock housings, not without further notice possible, such a self-locking "Rückdschreibsperre" in Provide lock housing. In this case the task exists in it, a barrier against pushing back a pushed out Bolt especially outside the lock housing, accommodate.
- a kinematic push rod connection has between a drive and a bolt one drive-side push rod and one with clearance or clearance subsequent bolt-side push rod on.
- On the Bar-side push rod is an angled spring tongue riveted, which acts as a pawl in a recess of the Faceplate engages and so pushing back the bolt or the push rod from the outside or by external action prevented. If the drive-side push rod, however is withdrawn, then this shifts for the time being within the exemption empty, so without the still blocked take along bolt-side push rod. It runs the drive-side push rod against the oblique spring tongue and lifts them out of the recess so that at Continued push rod drive and the bolt side Push rod can be withdrawn.
- a lock of the type described above, the compact and is stable and gives no free travel is characterized characterized in that the pawl is a one-armed lever fixed rotation axis next to the push rod or the bolt, approximately parallel to the freestanding device, is provided, the under spring bias under an approximately perpendicular to the direction of displacement the latch-side push rod or latch aligned stop surface on the latch side Push rod or on the latch for reminddrücksperre einschwenkbar is and that within the Freistell adopted a the Freewheel counteracting spring, in particular coil spring is provided.
- the lock can therefore in a bolt housing be provided as well as along the push rod, about in a corner drive or in a lock housing with latch or drive housing for a multi-bolt lock.
- the barrier is designed so that the kinematic connection in the direction to the bolt so in the reverse direction always the same length while in the retreating direction when stationary, latched, pushed out latch in the context of the exemption is extensible against spring force.
- This extension or The distance traveled is utilized to the pawl by means of a control surface or gate during compression to lift the spring. This allows the latch only at Retraction operation, so only by means of a key or a pusher of a multi-bolt lock are withdrawn. Any external use of force on the bolt will be through the pawl intercepted.
- the pen has the purpose at Retraction operation for the time being for the immediate bolt retreat Lost way after withdrawal of the bolt from his Catching up position in a striker to catch up and to compensate.
- a simple and expedient execution of the lock is thereby characterized in that at the front end of the drive-side push rod in extension of the same, a Bolt is attached to the said push rod that is the front end of the bolt a stop on the latch side Push rod opposite that a coil spring surrounds the bolt and that the coil spring on the one hand at the front end of the bolt and on the other hand at one Support of a bolt over its length Part of the latch side push rod is supported.
- bolt side than- Push rod can also mutatis mutandis formed a bolt stock be, then the drive-side push rod over a length of an exemption overlaps, between the Stops the exemption provided the spring as energy storage is.
- the pawl frontally a hook-like projection with an approximately perpendicular to Shifting direction of the bolt-side push rod aligned Supporting surface and if between the axis of rotation and the hook-like projection, the ramp surface for lifting the pawl in the displacement track of the control surface of drive-side push rod protrudes.
- FIG. 1 shows a view of Lock with retracted latch
- Fig. 2 the lock on advanced Latch with latched pawl
- Fig. 3 the Lock in retraction operation during the lifting of the pawl
- Fig. 3a is a simplified illustration of each other Sprung push rods in side view according to Fig. 3.
- a barrier against pushing back a pushed out Bolt comprises according to FIGS. 1 to 3a, a drive-side Push rod 1, with a bolt-side push rod 2 springy is coupled.
- the drive-side push rod 1 is via a multi-bolt lock, for example by a Key or by a rotatable in several positions Pusher and a gearbox, in particular with gear 3 and rack 4, moved.
- the bolt-side push rod 2 provides the connection to a bolt housing with gear deflection to a bar or she is even at her lying end formed as a bolt in a latch pocket a closing piece in a stick engages.
- Fig. 3a illustrates especially simplifies the resilient connection the said push rods 1 and 2.
- the drive side Push rod 1 overlaps the latch side push rod 2 thereby that on the push rod 1 a continuation of the same aligned bolt 5 is attached.
- the bolt 5 is located an end stop 6 as a driver on the latch side Push rod 2 opposite. Will the drive-side push rod 1 shifted up because the transmission gear 3, e.g. key operated, clockwise, then the pin 5 abuts the front face against the stop surface 6 and takes the latch side push rod 2 in the direction on pushing out a bolt with.
- a spring, in the embodiment as a cylinder spring. 7 is shown surrounds the bolt 5 and is supported on the head side at the front end of the bolt 5 and the foot side a support 8 of the bolt-side push rod 2 from. Of the Bolt 5 is passed through the support 8. Further Guides that only have a linear displacement of the push rods 1, 2 are provided, but in the drawings not shown. The latter show only the immediate Range of the return lock in the course of the push rod kinematics.
- a pawl 9 is also shown, on a fixed axis of rotation 10 by a spring 11 is biased against the push rods 1 and 2.
- the Operation of the pawl 9 will be described below with reference to Fig. 1 to 3 explains:
- FIG. 1 In the illustration of FIG. 1 are the push rods 1 and 2 in the unlocked position in which a latch withdrawn and a closure, e.g. a door unlocked is.
- the gear 3 e.g. through a Key
- the push rods 1 and 2 become common upward toward the locking position postponed.
- the displacement of the push rods 1 and 2 takes place together and at the same time, since the bolt. 5 the drive-side push rod 1 rests against the stop 6.
- the Pawl 9 slides during the displacement of the push rods in the locked position over a nose 12 and snaps behind the nose 12 such that it engages behind the stop 6. This position is shown in FIG. Should try be, the bolt and thus the bolt-side push rod.
- the bolt-side push rod 2 will be able held in Fig. 2. But if the drive, so that Gear 3 counterclockwise, e.g. through a key, is actuated, then remains while the latch side push rod 2 stand, but moves the drive-side push rod 1 down, at the same time compressing the coil spring 7, So charged as energy storage.
- the downstairs shifted drive-side push rod 1 carries a control surface 13, with a ramp surface 14 of the pawl. 9 cooperates. As shown in Fig. 3, the control surface pushes 13, the pawl 9 to the side, so that the latch side Push rod 2 is released and at discharge or expansion the coil spring 7 can move up.
