Description

The invention is concerned with a door lock lever with an integrated safeguard against unauthorized third party. This is based on the problem that in particular military vehicles must be secured against external opening from the outside Such a requirement is also for vehicles with people to be protected, including in the civilian area.

A door lock of the known type shows the DE 90 03 584 U1 , This is characterized by the fact that a one-step pressure mechanism is provided for the safety button connected to the safety button is a cam which engages in a rotatably mounted around the safety knob axial sleeve with internal teeth. The safety button itself is non-positively connected to a locking linkage.

A door lock for motor vehicles also describes the DE 25 22 301 A1 , This includes a latch and lever linkage for actuation by the exterior door handle. The inner handle has an inner locking button. The door lock can be controlled by means of a lock cylinder.

A locking device for a door with frame is the DE 198 14 229 A1 removable. The proposed additional Verrieglung consists of a hydraulic unit with a controllable solenoid valve and a piston rod, etc. Such a structure is structurally complex.

Known solutions for additional protection against foreign opening in the military area are an additional, internal lever or hook, which engages in the locking rod or the door lock lever and thus blocks the locking linkage and the door lock lever. As a result, opening from the outside is not possible. Unfortunately, the axis of rotation of this additional lever, which is designed as a screw, with the screw head outside the vehicle. This emergency opening from the outside is possible so that in an emergency, this screw can be unscrewed with a suitable tool, whereby the additional lever falls down and the door lock releases. But this also applies to unauthorized opening.

Another disadvantage is that an additional lever is needed and an additional breakthrough through the door or pan plate must be provided. This is associated with a ballistic vulnerability. In addition, it requires a complex emergency opening, as the screw is completely unscrew.

The DE 1 553 390 A deals with a locking device for doors, in particular for doors of freezers or cold rooms, which are provided with a lock and can be opened from the inside in case of emergency, when it is closed. For this purpose, the lock or the holder is connected to a detachable against rotation on the inside of the door held additional emergency handle by a door penetrating transmission member, a hollow shaft. In an emergency, the door is opened by unscrewing a locking screw from the emergency handle and the pivoting of the emergency handle, the lock via a hollow shaft brings the door handle outside in the open position. Again, an additional lever inside is needed.

The DE 577 758 A describes a locking device for two arranged on both sides of the door door handles, which is to be adjusted from the outer handle by a cylinder lock, the two door handles are connected by a traversing their axes usually locking bar with a door arranged on the locking device and the locking bar on a lying in the axis of rotation of the door handles longitudinally displaceable rod sits, which can be moved on the one hand by rotation of the inner door handle and on the other hand by rotation of the lock cylinder in the outer door handle to move the locking bar except blocking position.

The DE 93 00 921 U1 shows a panic or emergency opening device for a closure with an externally locking or lockable operating lever.

The DD 109 054 A1 describes a half-cylinder lock, the operation can be done by means of a key or knob and in which the closing operation is triggered by a swivel coupling.

The DE 41 09 633 C1 shows a door lock with an indication of the closed state as a retrofit kit for a Buntbartschloss.

The US 2,193,349 A describes a door lock with an inner and an outer knob, which are coupled together.

Here, the invention has the object to show a door lock that ensures a reduction of the ballistic vulnerability and allows easy and quick emergency opening. However, she must be safe against unauthorized third party unauthorized.

The object is achieved by the features of claim 1. Advantageous embodiments are reflected in the dependent claims.

The invention is based on the idea to provide a door lock lever with an integrated fuse, so as to prevent unauthorized opening, but in emergencies, such as after a mine or IED stop to allow opening by rescue workers.

The idea is technically realized in that the operating lever of the door lock consists of an inside and an outside handle, which are connected to each other via a hollow shaft of the door lock. On the hollow shaft is still the point of articulation for the door lock mechanism. A locking piece is controlled by a control cam provided with the additional locking lever. Another hollow shaft is trough firmly integrated in the door or tub sheet and preferably has slits. Through the slits the hollow shaft of the door lock is guided. The slits in the first hollow shaft and the second hollow shaft are designed so that they lie one above the other when the door is locked. Now, if an operating lever of the additional locking pivoted by 90 °, for example, the locking piece is pushed by the control cam in the operating lever of the additional locking to the outside, whereby it engages in the slots of the other hollow shaft. This locks the operation of the door lock.

At the outer end of the operating lever of the additional locking, so outside the shelter, located in case of emergency opening an emergency opening option. This can be a hexagon in the simplest case. Alternatives are a slot head, etc. Of course, a common size, but in exceptional cases can be a special size.

The emergency opening itself can be blocked against unauthorized persons from the inside by, for example, holding the operating bolt of the additional locking. A legitimate opening is possible in any case.

• 2 die Zusatzverriegelung aus 1 - geschlossen
• 3 eine schematische Schnittdarstellung aus 1,
• 4 eine schematische Schnittdarstellung aus 2.

Reference to an embodiment with drawing, the invention will be explained in more detail. It shows:

• 1 an additional lock - open - in a kind of plan view,
• 2 the additional locking off 1 - closed
• 3 a schematic sectional view of 1 .
• 4 a schematic sectional view of 2 ,

With 1 is a door lock with an integrated fuse 2 marked as additional lock ( 1 . 2 ). The door lock 1 consists of an inside and an outside or located operating lever 3 ( 3.1 . 3.2 ). The actuating lever 3 has a hollow shaft 4 and forms with this a constructive unity. With 5 is one in the hollow shaft 4 located articulation of the door lock called.

The additional lock 2 is mainly by a trough-mounted hollow shaft 6 , a locking piece 7 and an operating lever 8th educated. In the proposed execution is at the periphery of the actuating lever 8th a control curve 9 integrated, in which the locking piece 7 for blocking the door lock 1 to be led. At the other, outside (outside of the object / vehicle) lying end of the operating lever 8th an emergency opening 10 of the additional locking is provided. The emergency opener 10 can here a hexagon SW 19 a. The hollow shaft 6 is tub-proof in the door or tub sheet 11 the object or vehicle involved and preferably has slits 13 on. Through the slits 14 is the hollow shaft 4 the door lock 1 guided.

The locking piece 7 is formed such that it is the operating lever 8th comprises, at least partially, and in the hollow shaft 4 the door lock can intervene.

The operation is as follows:

The operating lever 3 the door lock 1 closes as usual. In this case, slits 13 in the first hollow shaft 4 and slits 14 the second hollow shaft 6 designed so that they lie one above the other when the door is locked ( 3 ). Will now the operating lever 8 of the additional lock 2 pivoted by 90 °, for example, the Sperrstuck 7 through the control curve 9 in the operating lever 8th the additional locking 2 pushed outward, causing it to slit 14 the further hollow shaft 6 attacks ( 4 ). This will be the operation of the door lock 1 locked, the operating lever 3 is not twisted or swiveled, as assumed.

In case of emergency, can via the emergency opening 10 the operating lever 8th the additional locking 2 the blocking or subordination by returning the locking piece 7 lifted in its original position and the operating lever 3 the door lock 1 be moved freely again.

The implementation of the idea is not limited to this one embodiment. Rather, the person skilled in the art knows various forms of a subordination of a lever. Also, the application area is not limited to vehicles of any kind on water, land or in the air, but can also be used in buildings and objects.
