Description

The invention relates to a locking insert for a lock with a bolt or latch bolt, which can be actuated by a lock bit of the insert held in a continuous opening of the lock.

Such a locking insert is, for example, a conventional cylinder lock insert, which is inserted into a door lock, a furniture lock or the like and can be actuated with an assigned cylinder lock key. Such a cylinder lock insert has the advantage that it meets certain security requirements and can also be operated with a relatively small key. - Other locks, especially door locks, to which lower security requirements are placed, are operated with a so-called collar bit key, which is, however, much larger than a cylinder lock.

Locks of this type are often used even when special security requirements are not made, for example within an apartment. Here it is usually only necessary that the lock can also be locked in addition to being actuated by a handle or the like, possibly also only from one side, such as, for example, in the case of doors to bath cells or the like. Then the use of a cylinder lock is not justified for cost reasons, while the use of a lock to be operated with a floppy bit has the disadvantage that the floppy bit is relatively large. That is why there are special locks for this purpose, their manufacture and storage additionally caused costs. The invention seeks to remedy this.

The object of the invention is to reduce the effort for the production and storage of locks, in particular for doors, furniture and the like, so that a single lock type can be used for a wide variety of purposes.

This object is achieved with a locking insert of the type described at the outset, which is characterized by an essentially cylindrical locking roller with a diameter adapted to the opening or a partial opening and a locking bit attached to the locking side and extending in the radial direction, with the locking roller on the end faces Actuating recesses and circumferential recesses for fixing the axial position are arranged on both sides of the lock bit between the lock bit and the associated end face.

Such a locking roller is a simple and inexpensive component to be produced, which is inserted and held like a cylinder lock insert in the lock in question and which can be actuated with a suitable handle adapted to the actuating recess. Such a locking roller can always be used advantageously if no special security requirements are placed on the locking of the lock.

The conditions become particularly favorable and practical when the actuating recesses are formed by a continuous slot extending in the longitudinal direction of the locking roller, the cross section of which is particularly adapted to the cross-sectional dimensions of a conventional cylinder lock key. Then the lock equipped with the locking roller can be locked or unlocked with any cylinder lock key.

This does not rule out the fact that this lock, which is provided with a locking roller, can also be operated with other handles or even with special keys, which essentially consist of a profile shaft. In order to prevent such a key from falling out of the locking roller when the door slams shut, the locking roller can have at least one radial bore for receiving a spring-loaded locking pin which extends into the slot and which fits into an associated locking recess of the separate key.

Since it is usually sufficient if the lock can be locked from one side, the locking pin is expediently arranged in the middle of the locking roller, so that a separate key can be inserted into the locking roller from each side and held therein by means of a locking connection.

The circumferential recesses for the axial position fixation can be arranged in the vicinity of the locking bit and can be arranged to receive snap rings. This embodiment is recommended if the outside of the lock housing is still accessible after the lock has been inserted into the door or to the door, as can be the case, for example, with locks for all-glass doors.

For other doors, for example wooden doors that have a lock pocket for receiving the lock housing, an embodiment is expedient in which the circumferential recesses for the axial positional fixing of the locking roller are formed by end pins, each of which can be fastened to the lock or to the door are assigned to the journal and a journal bearing to form an axial flange. The pins can have a smaller diameter than the closing roller and can pass into the closing roller with a shoulder forming an abutment for the end of the axial flange. In this embodiment, the closing roller held by the panels, as are simple components and can be adapted to the respective purpose. It is understood that the axial flange of the diaphragm has a continuous cylindrical opening _. has if the closing roller should be operable from the relevant side. In other cases, if no actuation of the closing roller from this side is desired, the diaphragm can also be closed. Similar panels can also be provided with an opening, the cross section of which corresponds to the cross section of a cylinder lap insert.

To compensate for manufacturing or assembly-related tolerances, the inner cross section of the axial flange can be tapered so that it can always fulfill its function as a journal bearing.

The diaphragms can also be constructed in a very simple manner; it suffices if each diaphragm has at least one locking projection for holding in an associated recess in the lock or the door.

The closing roller 1 shown in FIGS. 1 and 2 is an essentially cylindrical injection-molded part made of plastic or metal with a locking bit 2 integrally formed on half the length and a continuous slot 3 extending over the entire length. The diameter of the closing roller 1 is the diameter adapted the circular part of an insert opening for a cylinder lock insert. The length of the locking roller 1 corresponds to the length of a conventional cylinder lock insert. The cross-sectional dimensions of the slot 3 correspond to the cross-sectional dimensions of a conventional cylinder lock key, so that the locking roller 1 can be operated with such a key, that is to say it can be turned.

The closing roller 1 can also be operated with any other handle that is inserted into the slot 3. This can be a separate key that only has a longer profile. In order to prevent this separate key from falling out when the door in which the lock is inserted is slammed, the key can be held in the slot 3 with a latching connection. For this purpose, the closing roller 1 has a radial threaded bore 4 in the center for a retaining screw that can be inserted therein, with a pin, not shown, projecting into the slot 3 and supported on a spring, not shown, is secured. This pin then engages in an associated locking recess of the separate key and holds the key in the slot.

The locking roller 1 is inserted into the built-in lock like a cylinder lock insert. For the axial position fixing, the locking roller has circumferential marks 5 and 6 on both sides of the locking bit, into which snap rings, not shown, can be inserted, which rest on the outside of the lock housing, not shown.

If the sides of the lock housing are no longer accessible when installed, e.g. If the lock is installed in a lock pocket of a door, the locking roller can also be axially fixed in position with the aid of diaphragms 7 shown in FIGS. 3 and 4, each having an axial flange 8, the inside diameter of which is the outside diameter of the ends of the closing roller 1 trained pin 9 are adapted. The pins 9, which have a smaller diameter than the closing roller 1, connect to the closing roller 1 via a shoulder 10, so that the shoulder 10 can form an abutment for the end of the associated axial flange 8.

The aperture shown in Figures 3 and 4 has an oval to elongated base. On the back of the axial flange 8 extends on the one hand and on the other hand a locking projection 11 with which the panel 7 is held in an associated recess of the door.

It is not shown that the inner cross section of the axial flange 8 can be slightly conical in order to achieve a bearing of the pins 9 in the associated axial flanges 8 even with tolerances due to manufacture or assembly.

Otherwise, the panels 7 and the closing roller 1 are injection molded parts made of plastic or metal.

5 to 9 show further embodiments of diaphragms. In the embodiment shown in FIGS. 5 and 6, the cover 7 is placed on a stem 12 of an all-glass door lock 13, which is only indicated. In addition to the opening for the closing roller 1 formed by the axial flange 8, the diaphragm also has a further opening for a pusher 14.

The panel according to Figure 7 is used together with a lock, which carries a conventional cylinder lock insert as a locking insert. For this reason, in addition to the opening for the handle 14, this diaphragm 7 also has an opening 15, the cross section of which is adapted to the cross section of a cylinder lock insert.

The panel according to FIG. 8 is intended for a door which carries a lock with a locking roller 1 and in which the locking roller 1 should only be operable from one side. For this reason, the cover according to FIG. 8 has only one opening for the pusher 14.

In the embodiment according to FIG. 9, the closing roller 1, as already indicated at the beginning, is equipped with a separate handle 16, which in the exemplary embodiment shown is a simple lever, to which is connected a non-illustrated shaft which extends into the slot 3 and is held there with the locking connection described. This version is particularly suitable as a locking insert for doors that can only be locked on one side, e.g. bath cells and the like, with a panel according to FIG. 8 then being used on the other side of this door.

The locking roller 1 described is a simple and inexpensive component which can be used together with locks which are equipped with a locking insert. When using the locking roller, possibly together with the various embodiments of the panels, the manufacture and storage of separate locks without any special security requirements are superfluous, because the need for more or less security can be met by using either the locking roller or a cylinder lock insert.
