Description

The invention relates to a trap closure with reliable operation according to the preamble of claim 1.

Such a trap closure is, for example, with the subject of EP 1 119 675 B1 known. This trap closure consists of a fastened to a frame or the like first closure housing with a rear handle for locking receiving the trap of the trap closure, and a fastened to the door or the like second closure housing in which the case is slidably mounted. The trap can be opened by means of a handle against a spring force acting on it.

With this known trap closure, the problem is solved that in the conventional trap closures there is a gap between the two closure enclosures, in which a suitable tool, such as e.g. a screwdriver can be penetrated, with which it is then possible to push back the trap and thus open the door forbidden. This is possible even though the trap is completed.

With the EP 1 119 675 B1 Thus, the possibility is disclosed to protect doors against unauthorized manipulation.

A disadvantage of this known latch closure that it must be extremely stable for manipulation security and therefore made of a metal material. This increases the production and material costs of the trap closure.

In addition, even a slight distortion of the frame or the door leaf to be closed leads to an inaccurate closing of this trap closure, since with the known latch closure both closure housing of the individual components must meet exactly, so that the clasp ever comes into engagement. Thus, the sliding guide of the trapper is also susceptible to contamination.

The present invention is therefore based on the object to construct a trap closure, which is inexpensive to manufacture and ensures a secure closing of both closure housing even with warped doors or frames.

The objects underlying the invention are achieved by the features of the independent claims, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.

An essential feature of the present invention is that the clasp is pivotally mounted spring-loaded in the pivot axis of the handle, so that upon actuation of the handle at the same time the associated buckle is actuated because the handle engages a stop on the clasp and entrains it about the pivot axis.

With the pivoting arrangement of this latch compared to a spring-loaded sliding arrangement, there is the advantage of a reliable arrangement because it can be dispensed with contamination-prone sliding guides and acting on the clasp spring can be easily formed.

The spring extending about the pivot axis allows, upon reaching the maximum pivot position of the handle, that the clasp detaches in the region of the stop from the positive engagement of the handle and can be further pivoted in the pivoting direction.

It is particularly advantageous that the clasp is mounted on the same pivot axis, as the pivot axis of the lever and thus a particularly simple structural design is given.

The present invention dispenses with a costly closed metal housing and provides on both closure housings in each case at least one cover, which can be removed for the assembly of the individual closure housing, so that the underneath released Schraubaufnahmen can be used.

Such a use is that a screw or other fastening means can be passed through the previously hidden by the cover opening and can be inserted into a arranged at the bottom of the closure housing screw receptacle.

So it is possible to engage with a suitable tool in the opening and to fix the screw or the fastener.

The tool is for example a screwdriver.

For example, a screw can be placed over the opening in the screw holder and can then be tightened with a screwdriver. Since the screw comes under the closure housing in engagement with a thread, by tightening the closure housing can be fixed to the substrate.

After the individual lock housings have been fixed, the respective cover of the each lock housing are mounted on the lock housing and there securely lock.

The removal of such a cover is possible only by using tools.

A further advantageous embodiment of the invention is that each of the closure housing pivotally mounted to each have an inclined surface, which come into contact when closing the trap closure. The inclined surfaces preferably have the same angle.

However, the present invention is not limited to the presence of inclined surfaces. A use of straight surfaces, wavy or serrated Fälchen is possible with the invention trap closure.

Furthermore, in a further embodiment, the first closure housing mounted on an immovable frame has at least one protruding centering pin, which can engage in a corresponding recess of the second closure housing movably guided on the first closure housing.

The centering pin preferably has a conical shape, so that a centering of the centering pin upon entry into the recess is possible.

However, any other shape is conceivable that allows entry into a recess. Thus, the centering pin may be formed as a hexagon or generally as a polygon, or have a cylindrical shape or have a torsion-resistant shape.

Also, the invention is not limited to two centering, also a centering or a plurality of centering is conceivable.

Thus, it is possible that the individual closure housing can close safely even with a distorted frame or a distorted door leaf.

The first closure housing has a pivotable handle with a locking cylinder therein. In this lock cylinder, a key is inserted. The key actuates the lock cylinder at the end of a lock bolt is mounted in the radial direction.

To close the latch, the key and the lock cylinder are turned, bringing the latch to rest on the back of the clasp.

This contact connection prevents the clasp can swing backwards and thus the trapper can be opened.

By turning the key again, the locking bolt can be brought out of contact with the clasp, as a result of which it can be actuated again freely and the trap closure can be opened.

By tilting the handle over a pivot axis, the buckle attached thereto is pivoted backwards and is thus no longer in engagement with the projection. The spring-loaded handle rests against a stop in a form-fitting manner on the likewise spring-loaded clasp.

The invention is not limited to pivoting the lock cylinder together with the handle during tilting, and also a fixedly mounted lock cylinder remaining in the lock housing is encompassed by the present invention. In this case, the handle has a corresponding hole-shaped recess which receives the lock cylinder again during the closing operation.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

The closure housing 2 has a swivel handle 5 in which a key 6 is plugged in, as well as a clasp 4 on. The closure housing 2 opposite is the closure housing 3 arranged, which in the closure housing 2 guided clasp 4 can record.

To operate the trap closure 1 becomes the handle 5 of the closure housing 2 operated, with the handle 5 about a key 6 Can be locked and unlocked.

The handle 5 is about a pivot axis 16 in the direction of the arrow 17 pivoted.

Now the key 6 operated and the lock housing 2 unlocked, the handle can 5 over the pivot axis 16 be tilted.

At the bottom of the handle 5 is the clasp 4 attached, which upon actuation of the handle in the direction of arrow 17 also in the direction of the arrow 17 pivoted backwards.

The closure housing 2 has two covers at the top of the example shown here 12 on, which can be removed with the help of a tool.

The closure housing 2 opposite is the closure housing 3 arranged.

The closure housing 3 also has a cover 13 on, which can also be removed by means of tools.

When closing the trap closure 1 comes the lock housing 2 with his face 22 , its inclined surface 24 and his face 23 on the lock housing 3 opposite side in contact with corresponding corresponding surfaces of the closure housing 3 ,

2 shows the trap closure 1 in side view. The handle 5 is about the axis of rotation 16 in the direction of the arrow 17 rotatably mounted.
Below the handle 5 is the lock cylinder 18, which in a tilting movement of the handle 5 also in the direction of the arrow 17 from the lock housing 2 swings.

However, the invention is not limited thereto. In a further embodiment, the lock cylinder may also be fixedly mounted in the housing and only the handle pivots.

In the lock cylinder 18 becomes the key 6 plugged in.

Now the trap closure 1 closed, the face lays down 22 of the closure housing 2 to the face 25 the closure housing 3.

Likewise, the inclined surface sets 24 of the closure housing 2 on the inclined surface 28 of the closure housing 3 and also comes the face 23 of the closure housing 2 in contact with the face 26 of the closure housing 3 ,
Thus, the closure housing ( 2 . 3 ) each inclined at an angle to the closing direction, mutually associated inclined surfaces ( 24 . 28 ), which at closure of the trap closure ( 1 ) get in touch.

The present invention is not limited to a direct contact of the individual surfaces to each other. Even at a distance of 2 Millimeters the trap closure according to the invention closes reliably.

For centering the two lock housings 2 . 3 each other has the inclined surface 28 at least one centering pin 15 on, which in a corresponding recess 31 (not shown) of the closure housing 2 in the oblique surface 24 intervenes.

3 shows a sectional view of the trap closure 1 , You can see how the key works 6 in the lock cylinder 18 is introduced, with the key 6 and the lock cylinder 18 on the axis of rotation 33 lie.

Below the lock cylinder is a locking bolt in radial continuation 10 attached, which via a screw 20 with the lock cylinder 18 connected is.

Now the key 6 in the direction of the arrow 34 Turned on the axis of rotation, which is also on the lock cylinder 18 mounted locking bolt 10 accordingly in the direction of the arrow 34 turned.

In the longitudinal direction of the handle 5 is the pivot axis 16 over which the handle 5 in the direction of the arrow 17 is pivoted. The pivot axis is thereby from the axis 36 formed, on which also the clasp 4 is pivotally mounted.

The handle 5 lies over the stop 38 in the area of the Schenkachse 16 positively on the head 39 the clasp 4 on and thus takes them in a pivoting movement in the arrow direction 17 With.

The pivoting movement of the handle 5 but it gets through a nose 29 limited, which when pivoting about the pivot axis 16 in the direction of the arrow 17 at a stop 30 comes to the concern, bringing the handle with clasp not in the direction of arrow 17 can be swiveled.

The nose 29 is material integral with the handle 5 connected. In the present invention, not only a nose but also two or more such noses are claimed.

In order to ensure a better engagement, the clasp 4 has a spring 21 on which a spring tension around the pivot axis 16 transfers to the clasp around. This spring force acts a movement in the direction of the closure housing 3 opposite.

In a closed condition of a trap closure 1 grab the clasp 4 in a rear grip 7 of the closure housing 3 one. Now grab the clasp 4 in this grip 7 a, the top lays down 37 the clasp 4 to the horizontal projection 19 at the top of the rear handle 7 at.

When pivoted bolt thus the individual closure housing 2 . 3 no longer be separated in a vertical direction.

4 shows the lock housing 1 in closed condition.

Now the clasp picks up 4 in the rear grip 7 and comes to the projection 19 to the concern.

A repeated swinging back of the clasp 4 in the direction of the arrow 17 is by the screwed lock bolt 10 prevented. This was around the axis of rotation 33 in the direction of the arrow 34 turned and now lies at the contact surface 35 the clasp 4 and prevents them again in the direction of the arrow 17 over the axis of rotation 16 can swing back.

Would now the shooting bar 10 no longer in contact with contact surface 35 the clasp 4 This can also be at non-operation of the handle 5 in the direction of the arrow 17 be pivoted.

Would in 4 the locking bolt 10 not on the back (contact surface 35 ) the clasp 4 abut, you can the clasp in the direction of the arrow 17 around the pivot axis 16 swivel and operate, for example, with a screwdriver.

5 shows the bottom view of the trap closure according to the invention 1 , which is shown in the open state.

The locking bolt 10 of the closure housing 2 is here outside the engagement of the closure housing 3 ,

Now the locking bolt 10 not at the contact surface 35 the clasp 4 is possible, it is possible the handle 5 upwards in the direction of the arrow 17 to pry, so close 4 now out of the rear grip 7 is released and the shutter housing 2 . 3 again against each other in the vertical direction can be separated.

In the middle slot between the lock housings you can see the two noses 29 of the handle 5 ,

6 shows the trap closure 1 in the closed state, the lock bolt 10 in the direction of the clasp 4 was pivoted, and so on the contact surface 35 the clasp 4 rests so that it can not be pivoted in the direction of the locking bolt and thus of the locking bolt 10 is fixed.

7 show the exploded view of the latch closure according to the invention 1 , The closure housing in this case have individual covers 12 . 13 on.

So has the closure housing 2 the covers 12 on which come in pairs on the top of the closure housing for concern.

These covers are removable only via a tool and allow access to the underlying openings after removal 32 ,

In these openings 32 are the screw or nut shots, which are needed to the individual lock housing 2 . 3 to fix on a pad.

Likewise, the closure housing 3 the covers 13 which in turn has an opening 32 hide in which the screw or the mother shots are located.
