SI22716A - Profile cylinder insert - Google Patents

Abstract

The subject of invention is a profile cylinder insert which, when inserted into a normal lock, allows unlocking and locking of a door from the exterior side even in cases, when there is a key or a foreign body inserted from the other, i.e. the interior side, and can be squeezed out in the case of the profile cylinder according to the invention, particularly in systems with a knob on one side, which do not allow this. The operation of the profile cylinder according to the invention is based on a stronger pair of springs (3) in the core (1) on the one side of the door in comparison with the pair of springs (4) in the core (2) on the other side of the door, in which case it is possible to unlock or lock the door from the interior side by turning one core (1, 2) by means of a key (18) and a snapped-in bit (19) in a channel (20) of a ring (8).

Description

PROFILE CYLINDER INSERT

The subject of the invention is a profile cylindrical insert, which is inserted into a normal lock to enable the door to be unlocked and locked from the outside even in cases where a key or a foreign object is inserted on the other, inner side and can be ejected in the profit cylinder according to the invention, especially at one-button systems that do not allow this. The invention belongs to class E 05B 29/00 of the international patent classification.

io The technical problem that the present design of the profile cylindrical insert according to the invention successfully solves is to enable the door to be unlocked and locked from the outside by a key inserted or by an obstruction from the inside of the cylinder itself.

Known recent designs of cylindrical inserts have various safety features that prevent damage to the insert. They may consist of hardened pins in the core and body of a cylinder, magnetic systems that increase the number of combinations, and the like. These systems greatly increase the cost of making the cylinder insert, but do not reduce the number of mechanical damages to the insert itself. A special problem is the cylindrical inserts in classic locks (also with a button on one side), where direct access to the insert in the cylindrical insert is allowed on the other. , blankets or foreign objects, adhesives and similar materials that prevent normal operation or they prevent the lock from working, that is, opening it with a key from the outside.

The operation of the profile cylindrical insert according to the invention is based on a stronger pair of springs in a cylinder on one side of the door, such as a pair of springs in a cylinder on the other side of the door, which can be unlocked or locked by rotating one core with a key and locked chin in the ring channel. door from the inside. From the outside of the door, when the key is inserted into the core on the outside of the door, it pushes the key with its nose and pushes the spacer back, thereby also releasing the half-clutch into its bearing, thus eliminating the force of the first pair of springs. In this way, the ring has a relaxed channel into which the beard of the semi-clutch snaps. The door can be unlocked or locked from the outside when rotating the kernel.

The invention will be explained in more detail on the basis of an embodiment and the accompanying drawings, of which:

Figure 1 is a profile cylindrical insert of the invention in disassembled three-dimensional coaxial form;

Figure 2 shows the core of the profile cylindrical insert according to the invention when using only one spring.

The profile cylindrical insert according to the invention is shown in Fig. 1 in the disassembled three-dimensional coaxial shape without the housing of the cylindrical insert.

The profile cylindrical insert according to the invention consists of a core 1 of a cylindrical insert, a core 2 of a cylindrical insert, a pair of springs 3, a pair of springs 4, a semi-clutch 6, a thrust spacer 7 and a ring 8, which is drawn out of alignment with the profile cylindrical insert for transparency.

In assembling the aforementioned parts, we follow the following sequence: suppose core 2 lies on the inside of the door. Blind holes 9 are symmetrically rotated into the core 2 where springs 3 are inserted. The semi-clutch 6 is located in the bearing 10 of the core 2 and is subjected to constant pressure by the pair of springs 3. The thrust spacer 7 is located io with its widest circle 11 in the seat 12 such that it can be rotated - with switch 6 idle (or vice versa). When the ring 8 is positioned on the coaxial axis, the thrust spacer 7 is located inside. In the same way as a half-coupling 6 with a pair of springs 3 is pressed into the core 2, a half-coupling 5 with a pair of springs 4 is pressed into the core 1. The non-extended part 13 of the core 1 thus finds itself in a sliding grip with a circular recess 14 of the ring 8. On the core side 2 is an identical arrangement of the non-extended portion 15 in the ring 8. In the rectangular passage 16 on the semi-switch 5 is a squared shape 17 of the thrust spacer 7.

The operation of the assembled profile cylindrical insert according to the invention is based on a pair of springs 3 that are more powerful than a pair of springs 4. By rotating the core

2 locks the chin 19 into the groove 20 of the ring 8 with the help of the key 18. It is thus possible to unlock or lock the door from the inside. From the outside of the door, when the key 18 is inserted into the core 1 (which is shown in figure 1), the key 18 pushes the pusher spacer 7 back with its nose 21, thereby also releasing the half-coupling into its bay 10, thus eliminating the force of the spring pair 3. Ring 8 has thus released channel 20, into which the chin 22 locks. When the core 1 is rotated, it is possible to unlock or lock the door from the outside.

If the cores 1, 2 are longer, there is no room for blind holes 5 9. In this case, cores 1,2 are made as shown in Figure 2, instead of spring pairs 3, 4 is used for each pair only after one larger spring 3 ', 4'.

The advantage of the provided profile cylindrical insert is that it is possible to unlock and lock it from the outside of the door even when the io key is in the core 2 on the inside of the door. This can also be done with a button on the inside of the door, in which case only one larger spring is required in the core of the profile cylindrical insert shown in Figure 2, which lies in the axis of the button. An elongated circular rod can be mounted in the axle itself through the spring so as to push the pusher and spacer 7 forward, thereby removing a foreign key, blank or foreign object from the bed in the core 1 on the outside of the door. The known existing cylinder insert systems with the push-button do not allow this kind of operation, and it happens that when the wrong key or blank is inserted from the outside of the door, the knob rotates empty on the inside of the door.
