HANS EOLB GMBH & CO., 8065 Erdweg Screwless cylinder lock mounting

The invention relates to a cylinder lock for actuating a lock device, which in a simple manner in Receiving body of the lock is attached and positively secured in the locked position against disassembly.

The attachment of a cylinder lock in the receiving body is usually done today by screwing, in such a way that the screw is not accessible in the locked position, or by pinning. It has also already been proposed that the cylinder lock be like a push button by means of a leaf spring to lock in the receiving body. With suitable opening tools it is possible to use the cylinder lock or the lock cylinder to pull or knock out of the receiving body. The above-described connecting elements such as screw, A pin or a leaf spring opposes this attempt to open only a small amount of resistance.

According to the innovation, an embodiment is proposed which, with a simple design of the components, destroys the Makes lock in the manner described above impossible.

The essential feature of the invention is that the lock cylinder at its rear end receives a flange or similarly shaped projection, which in the locking position positively engages behind one or more locking lugs arranged in the receiving body «If on the front side of the lock cylinder, the lock cylinder collar is to be retained, the lock cylinder housing is expediently designed in two parts. The divided housing halves are expediently held by a plastic housing, which advantageously a resilient locking lug for securing the cylinder lock in the receiving body in the rest of the rotation area of the lock cylinder. It goes without saying that each individual feature of the invention is also on its own feasible.

In the drawing, the invention is illustrated using an exemplary embodiment. Show it:

Fig. 1 the cylinder lock in longitudinal section in the locking position;

Fig. 2 is a cross-section along section A-B; Fig. 3 as Fig. 1, but after turning the key; Fig. 4 is a cross-section along section C-D;

Fig. 5 the cylinder lock in longitudinal section, however offset by 180 ° compared to Fig. 1;

Fig. 6 shows a cross section according to section E - F.

In the receiving body 1 is that of the lock cylinder 2, the housing rails 3 and 4 and the outer jacket 5 existing cylinder lock stored. At the rear end of the lock cylinder 2 there is the puddle 6, which is expediently in one piece is formed with the horizontal cylinder. In the lock position engages this flange behind a shoulder 7 of the receiving body 1. For the push-button assembly of the cylinder lock the lock cylinder must be turned into an intermediate position are in such a way that the recess 5 provided in the flange 6 - as shown in Figure 4 · - in the region of the approach 7 lies. This enables the cylinder lock to be fully pressed in. In the other angular positions of the Lock cylinder β, the flange 6 engages behind the projection 7 and thus secures the cylinder lock against dismantling. This backup However, it is only required in the locked position, as there is a second angle range in the rest of the angle range that is not theft-proof Locking element secures the cylinder lock against unintentional disassembly.

When new the flange 6 on the lock cylinder of the lock cylinder collar 9 should be retained "and this lock cylinder collar 9 is also designed in one piece with the lock cylinder 2 is, the lock cylinder housing is suitably in shape formed in two parts by housing shells. The housing shells are expediently held together by an outer jacket. Because the outer jacket does not open when attempting to open it is more the load-bearing element, the outer casing can be made of plastic and the cylinder lock can be secured in all positions, except the locked position by an am Resilient locking lug 10 provided on the outer jacket, which is formed in one piece with the outer jacket, take place. The locking nose 10 engages in a recess 11 of the receiving body 1. Since the locking lug 10 is only a safeguard against unintentional pulling out of the cylinder lock and therefore no safety

CherungsfunTrtion fulfilled, the recess 11 can to the outside to be open. Projecting noses or ribs are advantageously arranged on the outer jacket, which provide a backlash-free connection enable between the outer jacket and the receiving body.

Of course, the housing must shells 3 and 4 opposite the receiving body 1 can be arranged so that it cannot rotate. This can be done, for example, that on the outer jacket 5 provided lugs 12 engage in the housing shells, the engagement expediently taking place at the point where the locking grooves 13 for the locking lamella, not shown, of the lock cylinder β 2 are located Bippen 14- take place. It is of course also possible to arrange one or more guide ribs on the housing shells that reach through the outer jacket and directly into the Engage receiving body 1.

If the housing shells are fastened in this way in the receiving body can that a forcible pulling out of the shells from the receiving body is impossible, the projection on the lock cylinder grasp the housing shells directly behind.

Instead of the plastic locking lug 10 can of course a separate resilient element also takes over the holding function of the cylinder lock in the receiving body. Also is in place of the plastic outer jacket shown, the connection of the housing shells is possible using two separate Jsings; also the housing shells can be designed so that they are form-fitting interlock, whereby the outer jacket can be omitted.

The approach 7 can also be formed on a part of the lock device, if this part is stable enough that at

an opening attempt to absorb forces.

If the cylinder lock is buttoned for assembly reasons without a key, that is, in the locked position of the cylinder lock and not - as in the exemplary embodiment "described - is to take place in an intermediate position, the projection 7" can, for example, be designed to be resilient be, in such a way that when buttoning the "projection on the lock cylinder pushes back the resilient approach and in the End position of the resilient extension engages behind the projection »

The resilient approach can be provided directly in the receiving body. However, it is also possible to use an existing resilient required for the overall function of the lock To use part of the lock equipment for this. If, for example - as is usual with certain locks - the The locking bolt is spring-loaded, a projection on the locking cylinder penetrating the locking bolt can Reach behind the locking bolt in the locked position. In order to facilitate the introduction of the cylinder lock in this embodiment To enable the locking position, the projection arranged on the lock cylinder acts with an inclined inlet groove or Incline on the locking bolt together. As a result, the locking bolt is counteracted by the introduction of the cylinder lock Moved by force of his locking bar spring until the projection has penetrated the locking bar and the locking bar spring Locking bolt pushed back into its original position and the positive locking is established. When the lock is operated normally, the projection on the lock cylinder comes into play never in the area of the inlet groove or slope provided on the locking bolt, so that the cylinder lock is secured against pulling out is guaranteed in every key position. The lock is used to dismantle the cylinder lock bolt to bring that the projection through the
