Abstract

In a locking mechanism for doors and gates, especially garage doors for one or two passenger cars, with a lock (6), especially with a rotary handle, a lock bolt which is movable by the latter out of a closing position into an opening position and which can engage into the floor or into the door frame, and force-transmission elements which are located between the lock bolt and each closing bolt and which can move the closing bolts back out of the closing position into a release position, in the closing position of the lock bolt the closing bolts being capable of being forced back into their opening position counter to spring force, provision is made, in order to avoid the known advantages and disadvantages of push rods and pull ropes with deflecting rollers or Bowden pulls and to make production and assembly easier, for designing the connecting elements as largely rectilinear steel wires (9, 10, 11) with a thickness of approximately 1.5 to 2.5 mm and for guiding them between the lock bolt (13) and each closing bolt, but only so far that, when the closing bolts are forced back out of their closing position, the connecting elements can shift aside resiliently and exert a return force on the closing bolts.

Description

The invention relates to a locking mechanism for doors and Gates, especially garage doors for one or two cars, with one Lock, especially with a twist grip, one of these a closed position movable into an open position Lock bolt, which in the bottom and or in the door frame grip, and wire-shaped connecting elements a straight section between the lock bolt and each Locking latch which removes the locking latch from the lock able to move back to a release position, whereby the locking bar in the closed position of the lock bar through the connecting elements against spring force in their opening position can be suppressed.

Special locks for gates, especially swing gates, are known and overhead sectional doors that have one or more parts Lock bolt (slide and lifting bolt, turn or swivel bolt) have with which a linkage, ropes or Bowden cables as connecting elements to the locking bolts who connected the can to known bolt locks such as lifting or turning bar or snapper with sliding or rotating elements term. In a known locking mechanism with the one features mentioned above (US Pat. No. 4,068,871) end the unguided wire-shaped connecting elements before Lock bolt in either a spring arch or a screw feather. The rotary movement of the locking handle becomes fully elastic constantly included in the spring arch or in the coil spring  be without a noticeable force effect on the closing le can be exercised if this should jam. At this locking mechanism for parts on motor vehicles, e.g. B. the hood or folding seats, it comes down to one greater clamping force exerted on the swiveling latches not at. Basically, the same applies to the Bowden cables, those for closing doors in motor vehicles in the DE-PS 9 43 569 and FR 2 499 141 are proposed.

The advantages and disadvantages of locking mechanisms with thrust rods, pull ropes with pulleys or Bowden cables are knows. Push rods require special shapes difficult to redirect and expensive to manufacture and Assembly. The latter also applies to steel cables.  

The known constructions have in common that springs or fe changing devices between the handle of the lock and the Locking bar in the lock or on the locking bar, which, for. B. as Snappers with their own spring are provided.

The invention has for its object one less dig lock mechanisms that can be manufactured and installed create, which are also characterized by special operational safety draws.

To achieve this object, the invention provides at the outset locking mechanism mentioned that the connecting elements te as largely straight steel wires with a thickness from about 1.5 to 2, possibly 2.5 mm between the lock bolt and each locking bolt is designed and guided, but only so far that when you push back the locking bar from the Dodge the closed position laterally and a reset able to apply force to the locking latch.

Serves as a new connection or power transmission element set a linkage, conventional ropes or Bowden cables as far as possible straight spring steel wire (- in Contrary to the easily plastic or permanently deformable egg send wire -) with a thickness of approx. 1.5 to 2.5 mm. The steel wire can also be somewhat hardened or best of spring steel hen to be laterally elastically deflectable. Its thickness is so choose that the operation of the locking system is easy Hand without too much stiffness is possible.

By using the steel wire as a lifting and pulling element for the locking latch becomes the necessary spring element in the Locking mechanism in the elastic to the side guided steel wire placed so that in the castle or on the ver final bolt no spring or the like is provided.

1 to 8 steel wires can be cut using a small punch adjustable on the lock and drawbar of the lock,  e.g. B. hookable in several places. Everyone's steel wires can operate a locking latch. In this way can use an ordinary lock to lock the door eight times, d. H. in eight places, without the actuation is too stiff, as when using Bowden cables. Since the steel wires themselves act as springs, there is no need moderately also the usual spring in the lock, against the opened is not. As a result, the necessary actuation energy is very ge ring.

The straight steel wire can easily move around 2 to 3 corners speaking bow without additional elements, such as scroll or Angle levers are directed to the locking bolt, the or the wires are only used to change the direction of an arc write and then just keep going. Thereby are manufacturers tion and assembly easier.

The steel wires are easily able to accommodate the movements of the To forward the lock bolt to the lock bolt, because they are in the closed position of the door or gate are stretched. The movement of the lock bolt on the connector steel wire is usually about 1 to 3 cm. That is enough for a safe operation of the locking strap gel in the open position.

Preferably, the wires are, at least partially, in one Hollow profile of the gate wing housed. It is convenient to several wires to different locking snaps this from Lock up to the introduction into a hollow profile of the gate, where they run parallel to each other, in a thin metal or Holding plastic tube together.

In this way, the steel wires are forced until they become one take a different direction of movement, a straight line in the guide tube to follow the path, causing the spring return of the wires the part of their longitudinal extension is limited, the immediate bar in front of the locking latches. Through this and through the  other planned tours, z. B. eyelets, the side elastic deflection essentially on the area in front of the Locking bars limited. This can typically be 30 to 50 cm long.

When unlocking the gate, especially by turning the Lock handle, the steel wires are through the lock bolt withdrawn and the locking latch unlocked or in the Release position moves and a lateral residual deflection the steel wires lifted.

With electrical gate actuation, e.g. B. when opening the gate, the lock bolt on which the steel is connected by a door drive wires are attached, also raised and the steel wires withdrawn. The locking bolts release the gate.

When the gate closes, each locking bolt is replaced by a pushed back or sloping ramp surface in a known manner pivoted back. By pushing back or back the steel wire will pivot by shortening the path to the Lock or curved for the first guide. Because of this he forced lateral deflection of the steel wire is an ela tical spring tension generated, which ensures that the or the locking latches when closing the gate in the lock snapped into place by the spring tension of the steel wire or wires steady and stays there under low tension until outgoing a new opening movement is initiated from the castle. Wuh in the meantime, no element of the lock is moved.

The steel wire forms one from the lock to the locking bolt one-piece connection that is capable of resembling one Bowden cable to be easily guided around one or two corners, which not only describes this path, but in contrast to Bowden cables, push rods or ropes a spring effect for the lock and the locking latch take over.  

By using the steel wire instead of a thrust bar, a Bowden cable or a rope are neither long holes such as B. with push rods, additional springs in Slide or swivel lock latch (snapper) or deflector elements or pulleys that emerge from a vertical a horizon Generate tal movement, necessary. Also the spring in the lock advantageously falls.

Another advantage is the use of steel wires for power transmission in that z. B. at one Sectional gate easily over the elastic steel wire movable section edges for locking latches on any Places can lead. The same applies to known sliding folds Gates.

It is also advantageous that the accommodation of the steel wire in a hollow profile, in particular to one side open hollow profile, a gate element can be made in the the steel wire is inserted through a small hole can. The profile can be used for trouble-free operation required guides or intermediate supports be brought.

The setting of a single locking snap happens for example by inserting the steel wire with a ha ken-shaped turn in a hole on the bolt of the lock ses. Fine adjustment is possible thanks to several staggered holes that is only in the range of a few millimeters. Such fine adjustments are easily possible since everyone is one individual steel wire of a locking bar individually on the lock bar can be fastened in a known manner. It can also be clamped will. The spring action of the steel wire makes it during adjustment without additional bracket removed lock spring held.

Finally, it is advantageous that the directional steel wire does not ne nipples, threads, holes, slots, screws, pins,  Bolts, protective spirals or hoses for fastening and the leadership needed. The steel wires only need one To be cranked by about 5 to 7 mm long by 90 °. This Cranks at right angles extend into a hole in the Swivel, slide and lifting bolts of the lock and serve as flexible, swiveling connection between steel wire and rie expediently they are with a cover in their Location held.

The same mechanism can be attached to a pushbutton on a übli Chen door lock can be applied.

An embodiment of the invention is based on a drawing voltage explained in more detail, which is a swing gate with a conventional lock with rotating handle and with snap locks shows.

A gate wing has a conventional swing gate lock 6 with a lock bolt designed as a lifting and sliding bolt 13 , on which 5 directional steel wires 9 , 10 and 11 of 1.5 to 2 mm (2.5) diameter are hooked or possibly clamped . The central straightened and hardened steel wire 11 extends perpendicular to a locking bolt into an opening in a floor profile at 5 . Two further steel wires 10 actuate a locking bar close to the ground at 3 and 4 on the left and right. The two other steel wires 9 lead to the upper lintel profile of the door leaf frame 12 in order to actuate two further locking bolts there at 1 and 2 .

The steel wires are supported at intervals of several decimeters by guides 7 on the inside of the gate frame. From the drawbar and lifting bolt of the lock to the floor profile, all 5 steel wires are combined in a short tube 8 , which moves up and down when actuated with the steel wires. You therefore do not have to move any movement in the short tube 8 , since they are moved with the tube at most 20, with certain locks up to 30 mm.

Of course, other locks can also be used the drawbars and lifting bolts to the side, e.g. B. to the left or right, or upwards. Also locks on set swivel levers or turntables can be used who the.

Finally, the steel wires can also be suitably, something stronger plastic wires, round or square cross cut to be replaced. Have such plastic wires elastic dimensional stability similar to that of steel wires therefore also not capable of elastic deformations of insignificant extent.
