Description

The invention relates to a furniture lock with a slide bolt, which can be used by a lock bit of optional Actuating and closing devices - rotary handle, Lock cylinder or beard key - can be driven where at the lock receiving the bolt and a tumbler housing an extending transversely to the slide bolt has taking, in each of which the lock bit taking, outer contourally uniform housing part of the Actuation and locking device against rotation engages, and wherein the housing part of the actuating and Locking device through a uniform fastening medium is secured in the inserted position, whereby the housing part of the actuating and closing device  from one that is flush with the castle ceiling lumpy, locking agent-dependent insert body formed which is made up of two spaced plate-like ones other connected elements and exists in its inter with a radially outward opening interacting directly with the slide bolt Lock bit of the respective actuation and closing device direction is functional and the ribbed and groove-shaped guide and centering means fit insertable into the lock housing and fixed on the bottom can be placed and when using a locking cylinder is connected to the lock cylinder housing that the Insert body through a recess in the slide bolt and the tumbler reaches through and that the insert body by in different positions in the lock housing is settable.

State of the art

A furniture lock according to the required type is by DE-PS 32 05 054, which goes back to the applicant previously known. This is the insert body with egg provided with a cone in a corresponding recess tion of the lock housing is inserted and centered and  the cone has a threaded hole, in the one penetrating from the outside of the lock housing wall Screw engages and the insert body in the lock housing axially locked.

The insert body is with a centering lug in the lock housing centered and between wall and lock housing axially secured.

The outer element has bevels or protrusions, which in corresponding forms of the castle ceiling to grab.

There is a point between the plate-like elements mandrel for hollow drilled straw keys or holes for continuous key blades arranged. The exterior of the plate-like elements is with two forms of the central keyhole for different types of attack of the castle.

The pointed mandrel is designed to be radially adjustable.  

There is one in the inside plate-like element radially directed bore arranged in the thread an adjustment screw is adjustable across the pointed mandrel, which radially adjusts the pointed mandrel.

The insert body is made as a one-piece injection molded part educated.

The lockbeard grips part of its beard height in one of two symmetrical to the lock's central axis trained the engagement of the lock bit serving Recesses and one symmetrical to the middle of the castle axis trained tumbler window, the Zu posture can be pushed back and forth at right angles to the bolt and in a locked position for the bolt control and arre is animalable, which is symmetrical to the central axis of the castle runs.

With a lock is for various backsets to educate development of a closed bolt shaft with a small amount terdornmaß the spring element preferably in a spring chamber arranged in the castle ceiling and through the Zuhal attack.  

Are in the castle ceiling as well as in the castle furnishings several recesses for the different arrangement the insert body according to the desired backset arranged.

In the construction according to DE-PS 32 05 054 is the Insert body integrated part of the lock right, but with this through a connector easy and quick to connect. Starting from egg A particular base lock can be opened by simply exchange of this insert a change to various actuating and closing devices and an reach directions. The actuation and Locking devices can be construction keys, architects keys, wrenches, punch wrenches, platelets-Zy linder, olives and different beard keys, e.g. B. Keys with different grooves and notches, be.

The base lock can be used as an overlying lock, A let lock or as a mortise lock, be formed that again can have different backset sizes or convertible or adjustable to different backset sizes can be.  

But it is also possible to use the z. B. with a Lock cylinder coupled insert body to be replaced or the slide bolt lock from a straw key convert a locking cylinder, in which in turn only the Insert body is exchanged.

Furthermore, after a certain amount of wear and tear Buckle, e.g. B. on the lock bit of a lock cylinder, possible without unscrewing the cover of the lock housing, to replace the insert body with the lock bit to to compensate for wear.

The type of fittings according to size, composition and appearance no longer matters when converting a base lock from an actuating and Locking device type to the other because of the use body itself flush, d. H. with the castle blanket closes. The wall thickness of z. B. a door, one The drawer or flap has no effect on the conversion ability of a base lock.  

The insertable insert body is used in the construction both as a guide and as a centering and bearing for the lock bit and for holding different lengths and different heights and differently drilled Culms or differently designed continuous Key blades with different shapes tung. This lock bit can either be in corresponding Wall parts of the insert body - z. B. with a stalk key-guided and stored by a pointed mandrel be, but on the other hand it is also possible in the insert body itself has a lock bit Arranged rotatably, which is then by a rotating hand got moved.

The lock is suitable for both furniture locks that only can be used for a stroke type, as well as for furniture locks used as right / left locks as well as for lad and flap are used.

After inserting the insert body into the lock is this in the radial direction through the centering and guide means precisely defined and can e.g. B. by an axially penetrating screw on the housing base Direction can be fixed. This is done without any  harmful tension, in particular, is caused by the feast do not pull such a screw or nut sideways Bending, bracing or other displacement of the Insert body reached, which leads to this Arre tation in the smallest space with extremely few Individual parts is possible. Through this type of lock There is one that every craftsman has to do no displacement of the insert body, so that the lock always keeps tour well. This type of locking is necessary also that there is always a coaxial bearing to the door hole is observed so that even with all types of loading beats (decorative fittings, key socket and front mounted rosettes for olives), which are detached from the Lock can be mounted, no problems from side Chen offset arise.

Another decisive advantage is that it can be found here hen that the safety assignment even at the place of use, e.g. B. with inclusion of the castle in a lock location, by the craftsman at the end consumer can be voted.  

After losing a key, the furniture leaves closed with one over a certain locking system open the ordered key without further ado, whereupon the Insert body from the lock housing that can be handled uniformly separated and the key receiving component out is exchanged for the person who lost the key has, e.g. B. another key with another To give closure. This exchange can be even faster be made if the door hole in the door is larger designed as the insert body and the insert can be removed through the door hole.

Through the use that can be used like a plug-in coupling body, it is possible by exchanging it, far going to mix and match numerous makes the.

This construction leaves on furniture locks the possibility of a central passage opening for to provide the actuating and closing devices and to include these in the drilling grid, which the on a vertical centerline holes for the befe is based on the dowel of the lock housing, whereby the fastening dowels for the lock housing symmetrical  to run through the central opening the lock housing transverse axis are arranged. To the For example, the fasteners on a espagnolette lock dowels for the espagnolette bearings of the mentioned vertical common center line be ordered. This results in a very simple one Drilling scheme with low investment costs for drilling plant. In addition, the drilling pattern for right and left door be the same.

This means that the same door can always be used for right / left use leaf drilled and factory-made with a base lock be designed. Only on site or during assembly furniture is used to decide how the door - on the right or left - is used. After the door is installed has been, so after it is clear whether the door for the right or left-hinged is used for this application if this is trained as a uniformly manageable component insert body inserted without lock disassembly, if the passage opening is larger than the insert is.  

A base lock thus facilitates typing, since that Basic lock as a sliding bolt or espagnolette lock, independent depending on the later direction of attachment at the factory the door can be installed. The direction of attack results then by inserting the handzuha uniformly inserting body, which can be done quickly and easily is.

Despite this extremely large number of uses Storage options are simplified and contained wrong orders.

The respective actuation and closing devices fit, there are various insertion openings on the furniture door 15, 18, 24 and 30 mm diameter for the rear push through the turning handle and for storing one Rosette or for penetrating a closing cylinder linders. Has the customer z. B. for a particular Drilling grid or for a specific insertion opening for Penetrate the rotary handle or the like he is with regard to the matching insert pers in its various configurations for under different turning operations are not restricted. He wants  Customer z. B. subsequently another handle, e.g. B. have a key with a different beard size this by simply replacing the insert body at sol Chen insertion openings possible that allow this.

Everything that sits in the furniture, for example rosette, straw of the key, cylinder body, bearing rosette one turn olive etc., make a correspondingly large in diameter Insert opening with appropriate cover required Lich.

It takes a base lock for the different ones Actuating and closing devices only the ent speaking number of inserts ready be while on the base lock itself and on the drilling grid no changes are required. As a result, he creates the investment for a very large variety of possible applications with regard to the fittings and the manipulations on the z. B. injection molding the un different insert bodies. These can be used as needed trap are melted down again, so that in Ver to conventional manufacturing processes capital for the extraordinarily large application pa lette is very low.  

In one embodiment according to claim 2, the Insert body from the opposite of the castle ceiling Side of the lock housing by a screw plug or the like secured against removal. This Screw plug pulls the centering cone into one appropriate protrusion on the inside of the housing Sewandung is arranged. The centering cone faces inside thread into which the screw plug can be screwed, which is also the opening of the castle here covers the housing. Of course, one needs Screw plugs not to be provided in all cases, however it is possible, the insert body in another Way of locking against removal in the lock housing, e.g. B. by bayonet lock or by retaining screws.

The fact that a pointed mandrel in the radial direction, ie ra dial to swivel the lock bit, adjust bar, can be used with one and the same insert body different brands of beard keys without any problems use. These beard keys are often with the The naked eye hardly or not at all regarding their dimensions  indistinguishable. Only after introduction to that One notices the castle that the castle interior is not can be operated. By adjusting the pointed mandrel often only slight differences in size compensated be by the pointed mandrel in a radial direction is adjusted and then locked. This adjustment can e.g. B. by in a radial direction in a Bore of the insert body guided grub screw be made (claim 7).

For example, it is possible to have a base lock for three to use different backset, and that at corre appropriate variation of the desired handling, d. H. that the desired hand for each backset have, e.g. B. construction key, pen key or beard key sel be used according to appearance, size and design can, only the associated insert body needs to be replaced. At the castle interior itself or on the outer dimensions of the furniture lock nothing needs to be changed.

task

The invention has for its object a cylinder Furniture lock according to the presupposed genre to make it suitable for a wide variety of directions gen - right, left, below and above - without dismantling the Castle furnishings can be changed later.

solution

The object is represented by the claim characteristics resolved.

Some advantages

In the embodiment of the invention, a furniture lock can be from the outside, d. H. without the lock cylinder and Having to take apart or separate the insert body, switch to the different types of stop. Therefor no complicated special tools are required. Rather, the convertibility can be shifted by a  catch-like driver or the like take place, which after a certain angle rotation back into one positive locking position engages in the cylinder core and lock bit are connected.

While in the construction according to DE-PS 32 05 054 for different directions - right, left, up and below - four different locking devices each with lock cylinders and integrated lock differences were required in the furniture lock according to the invention only one cylin each that required with an insert body, plus Closure. This significantly reduces inventory graces what the variety of possible closings means a very large saving.

The changeability from right, left, up and down leaves very quickly with the furniture lock according to the invention make so that with the installation of such locks familiar person depending on the available bulletin the furniture lock within a few seconds the lost parts are created - practically with egg nem handle - on the required stop direction can adjust.

In the drawing, an insert body 1 in the lock according to FIG. 1 is designed for actuation by means of a nut body or a nut nut.

The insert body 1 can engage in various base locks. These include screw-on, inlet and mortise locks which, for. B. as a slide bolt, espagnolette, push rod, hook bolt, latch and compass bolt locks etc. can be formed in various backset dimensions and dimensions, surfaces and materials.

These basic locks can be handled in different ways conditions such as B. beard keys with grooves and tumbler beard in different beard dimensions, wrenches, Key wrench, lock cylinder, nut versions for one plug-in handle, and also for Locking systems for construction cylinders can be combined.

The reference numeral 2 denotes a door, while 3 illustrates a cylinder lock designed as a rivet cylinder, which is arranged in a bore 4 with a rosette 5 .

With 7 , a lock case of an espagnolette lock is characterized, while the espagnolette driven by the lock mechanism is concerned with the reference numerals 8 and 9 , which have hooks 10 and 11 at the ends.

With the reference numerals 12 , 13 , 14 and 15 dowels are characterized. All dowels 12 , 13 , 14 and 15 lie on a through the center of the bore 4 for the Zylin derschloß 3 extending vertical line. The two dowels 13 and 14 are connected to the lock housing 7 , while the dowels 12 and 15 are coupled to bearing bushes 16 and 17 for the rotary rods 8 and 9, respectively.

In all shown in the drawing locks a sliding bolt 18 is centrally axially disposed to lock the mid cross 19th

The slide bolt 18 can be closed both from the inside and from the outside or by other hand, e.g. B. can be actuated by a press mandrel.

It can be clearly seen from FIG. 1 that the slide bolt 18 is displaceable in the direction of the central axis 19 of the lock and perpendicular to the bore 4 .

The cylinder core is in the illustrated Ausfüh approximate shape to the cylinder lock 3 and thus zen trically arranged to the bore 4 .

The tumbler and its training can be designed and arranged as in DE-PS 32 05 054. In particular, it is possible to form the slide bolt 18 and the tumbler (not shown) with respect to the lock transverse center axis 19 symmetrically and in one piece.

The insert body is basically designed and arranged as described in DE-PS 32 05 054. In particular, the insert body 1 in all embodiments preferably consists of two plate-shaped elements spaced apart from one another, between which an intermediate space is arranged. One of the plate-shaped elements is formed by the wall 20 of the insert body 1 and the other plate-shaped element running parallel to the wall 20 by a flange 21 connected to the cylinder housing of the cylinder lock 3 , with which the insert body 1 is connected via webs 22 and 23 is. For this purpose, the webs 22 and 23 each have an orogonal outstanding rivet 24 and 25 , which penetrates holes 26 and 27 ( FIG. 2) indicated only by dash-dotted lines and is then connected in one piece by riveting.

The core 29 , which can be rotated by a key 28, has at its free end section a stepped bore 31 penetrating it orthogonally to its longitudinal axis 30 and opening out at both ends on the periphery of the core 29 .

As is apparent from Fig. 6, the bore 31 consists of the bore portions 31 a and 31 b, wherein the bore section 31 a is larger in diameter than the bore portion 31 b. Cut in the larger diameter Bohrungsab 31 a is a compression spring 32 is arranged, on the one hand, b is supported on the annular collar in the region of transition to the smaller diameter bore portion 31 and on the other hand a locking pin 33 beauf beat, which is designed as a hollow pin.

The between the spaced walls 20 and 21 angeord designated nut body 34 with nut lever 35 is placed with a bore on the core 29 and by the locking pin 33 with the core 29 in one piece, but releasably, the verbun. For this purpose, the nut body 34 each pair of wise and offset by 90 degrees to each other arranged locking recesses 36 , 37 and 38 , 39 , which each run in pairs coaxially. Each of the locking gel recesses 36 , 37 and 38 , 39 consists of two differently sized recess sections, of which, for reasons of simplification, only the sections 36 a and 36 b ( FIGS. 6 and 7) have been provided with reference numerals. The other locking recesses are designed in the same way.

All locking recesses 36 , 37 , 38 and 39 are - seen over their diameter - formed by only half holes, so that means that the locking recesses 36 to 39 open up into the end face 40 .

The locking pin 33 is always only in the section from 36 b or in the corresponding other locking sections. Since the locking sections 36 a and the corresponding other locking sections with a smaller diameter of this type open to the outside, that is to say to the periphery 41 of the nut body 34 , one can use a pointed object which exerts a force on the locking pin 33 against the restoring force of the spring 32 , the locking pin from the corresponding locking recess, for. B. from the Sperrungsver recess 37 ( Fig. 6) by moving inward into the core 29 in a final locking position, whereupon the nut body then z. B. 90 degrees or an even number that corresponds to the corresponding locking recess 36 , 37 , 38 or 39 corresponds. Thereafter, the pressure on the locking pin 33 is removed, so that the spring 32 pushes the locking pin 33 after passing one of the locking recesses 36 to 39 back into one of the locking recesses and thereby retains the nut body 34 with respect to the core 29 in a form-fitting manner. In this way it is possible to set the locking insert in question to different stop directions. This is illustrated veran in Figs. 8 to 15. The locking pin 33 has been adjusted by corre sponding change so that the locking insert for the upper lock, right lock, left lock or bottom lock can be used. The lock can be switched over when the cylinder lock 3 with insert body 1 and nut body 34 is assembled in one piece. A build from each other is not necessary because the locking pin Ver 33 between the spaced walls 20 and 21 is accessible ( Fig. 7).
