Definitions

• the present invention relates to an arrangement as part of a locking mechanism in the manner of the preamble of claim 1.
• locking mechanism is to be understood as an at least partially mechanical structure which serves to lock a movable part with respect to a fixed part.
• espagnolette mechanism which usually closes by means of three locking elements, a bolt and two locking hooks.
• Espagnolette mechanisms are used to lock cabinet doors.
• Each locking mechanism can assume a locked position and an open position. In order to be able to move back and forth between these two positions, each locking mechanism has a drive which accepts a drive movement.
• the locking mechanism converts this drive movement, usually a rotary movement over an angle of 90 °, into one or more locking element movements, the kinematics of the locking element movements being dependent on the respective locking element.
• a espagnolette mechanism makes a 90 ° drive movement on the one hand into one
• a locking mechanism in the locked position initially only prevents unintentional opening of the locked object. If the object is also to be secured against unauthorized opening, some locking mechanisms can be further developed into a lock by incorporating a cylinder core into the locking mechanism. Cylinder cores have tumblers that block the locking mechanism in the locked position. The blockage can be removed by inserting a suitable key into the cylinder core. Inserting the key causes the tumblers to be drawn into the cylinder core, which releases the locking mechanism from being blocked. In some locks, the cylinder core itself serves to drive the locking mechanism, in other locks a separate drive element of the locking mechanism is blocked by means of the cylinder core.
• Furniture locks are offered in modular form today. Elements of such construction kits are initially different locking mechanisms such as slide or rotary latch mechanisms. The respective locking mechanisms are often still available in a right and a left version. All of these locking mechanisms have a uniform interface in which a drive element can be inserted.
• kits for furniture locks have been developed that achieve a smaller number of parts, among other things, that the locking mechanisms for
• Modules with a right / left switchability of the locking mechanisms are known, inter alia, from DE 196 29 258 C1 and from DE 197 03 331 C2.
• the object of the present invention is therefore to create a modular system for furniture locks, the locking mechanisms of which can be used right / left without additional effort.
• An advantage of the invention over the prior art is that the locking mechanisms equipped with the arrangement according to the invention have a real right / left usability, whereas in the prior art only locking mechanisms with right / left convertibility were known.
• the position of the locking mechanism is clearly recognizable from the position of the cylinder core.
• the invention can be carried out such that the lock is always in the locked position when the slot of the cylinder core is aligned vertically.
• the locking mechanism according to the invention with the features of claim 3 enables retrofitting a locking mechanism.
• Mandatory locking means that the key can only be removed from the cylinder core when the lock is in the locked position.
• the forced locking can be retrofitted after assembly of the lock and also be removed again.
• the features of a retrofittable locking mechanism described in claim 3 can advantageously also expand locks that are not the subject of claim 1.

• FIGS. 1 to 4 The basic principle of the arrangement is to be explained with reference to FIGS. 1 to 4.
• the elements shown are abstracted links of a locking mechanism.
• the links are arranged in a manner R that they can be used in a right-hand lock.
• the arrangement consists of a housing 1, an output element 2 and a drive element 3.
• the housing 1 has an essentially hollow cylindrical shape, output element 2 and drive element 3 are rotatably mounted in the housing 1.
• the housing 1 is provided on its end faces with two pairs of stops 4, 5 and 6, 7.
• the stops 4, 5 serve to limit the angle that the driven element 2 passes over in relation to the housing 1 during a rotational movement.
• the area between the stops 4 and 5, in which the output element can move, is referred to here as the output angle range ⁇ .
• the output angle range ⁇ comprises a semi-circular angle.
• the stops 6 and 7 limit a drive angle range ⁇ in which the drive element 3 can move.
• Drive element 3 and output element 2 cannot cover their full angular ranges ⁇ , ⁇ within the assembled arrangement. This is due to the fact that they form-fit 8 to form a non-rotatable bandage 2, 3 are united, whose angular mobility ⁇ results from that of the intersection of the individual angular ranges gleiche, ⁇ . Since the angular ranges ⁇ , ⁇ only overlap on a quarter-circle sector 9, the angular mobility ⁇ of the bandage 2, 3 is limited to 90 °.
• FIGS. 1 to 4 can thus be understood as a simple rotary bolt lock, in which the output element 2 symbolizes a rotary bolt.
• the rotary bolt (output element 2) is in a vertical position (FIGS. 1a, 1b, 1c, 3a 3g, 3f)
• the rotary bolt lock is in the open position.
• the drive element 3 which can symbolize a rotary lock or a locking cylinder in a rotary bolt lock, is rotated by 90 °, the rotary bolt assumes a horizontal position (FIGS. 2a, 2d, 2e, 4a, 4i, 4h), which corresponds to the locked position.
• the drive element 3 is a locking cylinder, this should be lockable in the locked position by means of tumblers in the housing 1, a corresponding cylinder housing. If the drive element 3 (cylinder core) is blocked in the locked position in the housing 2 (cylinder housing), the rotary bolt lock is locked.
• the advantageous right / left usability of the arrangement according to the invention becomes clear by comparing FIGS. 1 and 2 with FIGS. 3 and 4.
• the arrangement can namely be mounted next to a first way R usable on the right ( Figures 1 and 2) in a second way L usable on the left ( Figures 3 and 4).
• the rotary latch takes its locking position to the left of the housing.
• the rotary bolt lock can be used for a door hinged on the right. If the same components 1, 2, 3 are mounted in the manner L, the lock is suitable for doors hinged on the left.
• the output element 2 can thus also serve to drive a downstream follow-up mechanism, such as, for example
• FIGS. 5 to 10 show components of a furniture lock in the form of a screw-on lock with a rotary knob.
• the furniture lock is made up of components of a modular system, in which the teaching on the design of right / left usable locking mechanisms is implemented.
• the arrangement according to the invention is accommodated in a rotary knob 10.
• the drive element is a cylinder core 11
• the housing is a cylinder housing 12
• the output element is an adapter 13, which comprises an eccentric 14.
• the eccentric 14 is used for the translatory drive of a bolt 15, with the aid of which the rotational mobility of the rotary knob 10 can be blocked.
• the rotary knob 10 can execute a 90 ° closing movement which is initiated via a rotary knob output 16 into a locking mechanism which is connected downstream of the rotary knob 10 and is not shown in the drawing and which is housed by a lock case 17.
• the cylinder core 11 has spring-loaded tumblers 18 which extend radially to the longitudinal axis 19 of the cylinder core 11.
• the tumblers 18 are pressed over part of their length into grooves 20 of the cylinder housing 12 by spring force when the cylinder core 11 is in the blocking or in the open position.
• This form-fitting locks the cylinder core 11 in the cylinder housing 12 in the circumferential direction, which makes it impossible to move the bolt 15.
• the cylinder core 11 can only be rotated in the cylinder housing 12 if a suitable key 21 has been inserted. Then the tumblers are completely pulled into the interior of the cylinder core 11, whereby the positive connection between the cylinder core 11 and the cylinder housing is canceled.
• the cylinder core 11 can be removed with the help of a special disassembly key 22.
• the disassembly key 22 pulls a further locking tumbler 23 into the cylinder core 11, which prevents the cylinder core 11 from being pulled out along its longitudinal axis 19.
• An additional gain in safety, illustrated in FIG. 8, can be achieved by providing the locking tumbler 23 with a nose 24, which does not move into the cylinder core 11 even when a dismantling key 22 is used.
• the contact surface in the cylinder housing 12, against which the locking tumbler 23 bears in the pull-out direction is provided with an opening 25.
• the lug 24 can be guided into a groove 20 and pulled out of the cylinder housing 12 together with the cylinder core 11.
• the opening 25 is to be positioned in the cylinder housing 12 in such a way that the nose 24 can only get into the groove into which the tumblers 19 also move in the open position of the cylinder core 11. In this way it is ensured that the cylinder core 11 of a closed lock cannot be pulled.
• the rotary knob 10 can be exchanged with the aid of a simple assembly tool 26.
• the assembly tool 26 pierces the entire rotary knob 10 in its center and unlocks an assembly latch 27 which holds the rotary knob 10 in the lock case 17.
• a locking element 29 in the form of a simple pin is inserted into a receiving opening 28 in the cylinder housing 12.
• This blocking element 29 prevents the cylinder core 11 from being able to move to the open position by correspondingly restricting the closing path, that is to say the angular mobility ⁇ (FIG. 10).
• the tumblers 18 cannot extend out of the cylinder core 11 in this angular position, since a section 30 of the inner circumference of the cylinder housing 12 prevents the tumblers 18 from protruding. As long as the tumblers 18 do not protrude from the cylinder core 11, the key 23 cannot be removed. The user is thus forced to put the lock in the locked position beforehand.
• the forced closure can be released at any time by removing the blocking element 29 from the receiving opening 28.
• Locks that can be used on the right / left require two receiving openings 28L and 28R.
