The invention has the object of developing the generic lock benefits advantageous.

The object is achieved by the invention specified in the claims, wherein the dependent claims are not only advantageous developments of the main claim mortise lock, but also represent independent solutions to the problem.

First and foremost, it is provided that the two housing sections can be fixed to one another in the different spacer layers. The lock according to the invention thereby has a telescopic lock case. According to this embodiment, by telescoping the lock case, the distance, namely the distance from the presser nut axis to the key axis of rotation be adjusted to different, common dimensions. Usually the distances at room doors are 72 mm and at building doors or entrance doors 92 mm. The inventively designed lock can thus be easily adapted to the particular distance required. Preferably, the two housing sections can be moved against each other between two stop positions, wherein a stop position represents the maximum distance between follower axis and key rotation axis and another stop position represents the minimum distance between the follower axis and key rotation axis. There are provided connecting means for firmly connecting the two housing sections in the different spacing layers, so that the lock housing is to be handled as a unitary lock body in each differently set distance between the follower axis and the key axis of rotation. The lock can be combined with differently shaped cuffs. An existing from a steel rail forend is this releasably bolted to the lock housing. The differently shaped cuffs differ essentially by the distance between the trap window and latch window. The cuffs can also differ by the size of the bolt or the size of the trap. The mortise lock according to the invention is preferably part of a kit which consists of a large number of cuffs and a plurality of differently shaped locking heads and latch heads. The latch heads and the latch heads can be combined with a latch tail or a latch tail, which is arranged displaceably in the lock housing. In a preferred embodiment of the invention, in each case a lock cover part and a lock floor part in the direction of the respective other lock cover part or lock floor part projecting long hole tabs. These long hole tabs each carry a slot which extends parallel to the forend. These long hole tabs underlap each other the other lock cover part or Schlossbodenteil. The respective other lock cover part or lock floor part forms a mounting opening into which a fastening screw can be screwed, which passes through the respective slot. By tightening this, for example, screwed into the internal thread of a arranged in the lock housing Befestigungsböckchen mounting screw, a clamping fit can be achieved, so that the long hole tab is fixed immovably to the other castle floor part or lock cover part. The lock can be equipped with a changing device. The changing device consists of a length-variable, in particular multi-part change lever, which can be operated by the key or by the closing member of a lock cylinder. Upon a shift of the change lever, the case is withdrawn by key operation. The two sections of the change lever can be connected together in different positions. For this purpose, a connecting member is provided. The connecting link is to be released if the removal of the lock is to be adjusted by moving the two housing sections. In a preferred embodiment, the connecting piece is formed by a stop member, which is clamped on an upper portion of the change. This stop piece is supported on a step of the lower change section, which can be acted upon by the closing member of the lock cylinder.

In a variant of the invention, it is provided that the two sections of the change are connected to one another via a spring clip. The spring clip may have a nose or a pin which can be inserted through mutually aligned openings of the changing sections in order to connect the two changing sections in a defined length in a form-fitting manner.

In a development of the invention, which has independent character, the backset of the lock can be varied independently of the preset distance. To vary the backset several Distanzböckchen are provided, which can be arranged between Stulprückseite and lock housing narrow side. The Distanzböckchen can a through hole have, through which the fastening screw can be inserted through which the forend can be attached to the lock housing. In a preferred embodiment, the Distanzböckchen rear niches, can dive into the front projections. As a result, a plurality of spacers can be combined with one another in a form-fitting manner to set larger mandrel dimensions.

In a further variant of the lock it is provided that lock cover parts and lock floor parts are each formed by stamped and bent sheets. In another variant, it is provided that at least part of the lock floor or preferably both parts of the lock floor are formed by shaped parts. These may be zinc die castings that store the mechanical elements such as latch, pusher and trap. The connection between the bolt head and bolt tail is preferably carried out by means of a fastening bolt accessible from the castle broadside. The connection between the case head and the latch tail is designed in such a way that the catch can be displaced with respect to the case head in the extension direction of the forend. The case head is then held on the one hand by a positive engagement on the latch tail slidably and on the other hand fixed by its location in the trap window in the extension direction of the forend. Preferably, a mushroom-shaped mounting pin is seated on the back of the case head facing away from the latch slope. The diameter-enlarged head of the fastening pin engages in a direction extending in Stulperstreckungsrichtung C-shaped groove of the case head. The case head is preferably guided positively in the transverse direction to Stulperstreckung. From the two facing away from each other wide side surfaces of the latch tail protuberances protrude, which are guided in guide slots of the castle cover part or Schlossbodenteil.

In a further embodiment of the invention it is provided that, instead of individual Distanzböckchen a, extending substantially over the entire length of the lock spacer bar is provided. The length of the spacer bar corresponds essentially to the length of the lock housing in the extended state. The spacer strip has notches that mark places where the spacer bar can be shortened by sawing off a section. The shortening of the spacer bar can also be done at predetermined breaking points by canceling a section. It can be arranged side by side, in order to set different mandrel sizes several, in particular also different thickness trained spacer bars. The spacer strips can then interlock positively. You can also interlock positively in the facing to the forehead narrow side of the lock housing.

In a further development of the invention, it is provided that the length of the trap window of the forend extending in the direction of the stile is greater than the dimension of the trap extending in the corresponding direction. It is provided a guide piece, which rests against the back of the forend and which protrudes partially with a projection which forms a filler in the fall passage window of the forend. The filler can protrude either above or below in the trap window, so that the distance between the latch and latch can be influenced by reversal of the guide piece.

The above-mentioned spacer strips have recesses which can engage in the projections of the spacer strips. The material thickness of the projections corresponds to the material thickness of the guide piece. The guide piece is thus in a recess of the spacer bar, if a spacer strip is used. Otherwise, the guide piece is located in a recess of the upper housing part.

In one embodiment of the invention, it is provided that a portion of the housing is covered by a housing shell. The housing shell may be a stamped and bent part. This surrounds at least the upper housing part like a shoe and with a housing extension also a portion of the lower housing part. The lower housing part can be pulled out of the housing shell. The housing shell only needs to be plugged onto the two-part housing. It can be kept there by means of pin projections positively. In the housing shell may be an opening through which a tool can be inserted into the interior of the lock housing to extend the change lever.

The invention further relates to a kit consisting of a mortise lock with an upper and a lower housing portion which are fixable to each other in different spacing layers, a plurality of cuffs, which differ at least in terms of the distance from trap window to latch window. The kit may also include differently designed and especially different length case heads and locking heads, as well as a variety of distance blocks. With this kit locks with different mandrel sizes and different distances can be assembled in a simple manner.

The embodiments illustrated in the drawings relate to a mortise lock, as it can be used by key services for suburb exchange of a defective lock. The lock has a lock bottom formed from an upper lock bottom part 3 and a lower lock bottom part 4 and a lock cover formed from an upper lock cover part 1 and a lower lock cover part 2. Castle ceiling and castle floor are at a distance from each other. In the distance space between the castle floor and the castle ceiling is a latch 7, 8, a case 5, 6 and a pusher 9th to retract the case 5, 6 against the restoring force of a latch spring 19. Below the bolt 7, 8 is a profile opening 12 for insertion of a profile cylinder. In the Fig. 3 the closing member 20 of the lock cylinder is shown. From it protrudes radially from a cam 21, with a tumbler 35 can be lifted against the restoring force of a tumbler spring 36 so that the tumbler 35 can be lifted when turning the lock cylinder on the touring pin 34. In this case, the cam 21 also engages a guided on the lock bottom 4 bolt tail 8 to move it linearly. With a fastening screw 31, which is accessible from the Schlossbreitseite, the bolt tail 8 is positively connected to a bolt head 7. The bolt head 7 extends through a bolt window 24 and a fortified on a longitudinal narrow side of the lock housing forend 22nd

Above the locking window 24 is a trap window 23 through which the case head 5 of the case protrudes. Front side of the case head 5 has a case slope and the back of a mounting pin 47 with an enlarged head. The enlarged head of the fastening pin 47 engages in a fastening groove 48 with a C-shaped cross-section. The case 5 is thus displaceable relative to the case head 6 in the extension direction of the forend 22.

The latch tail 6 has projecting guide lugs 37 projecting from one another, which guide slots 38 of the lock cover part 1 or the lock floor part 3, so that the latch tail 6 can be displaced parallel to the displacement direction of the lock 7, 8.

At a rearward stage of the latch tail 6, an arm of the follower 9 engages. The follower 9 is rotatably mounted in circular bearing openings 10 both in the lock cover part 1, as well as in the lock bottom part 3. The nut can be used against the restoring force of a pusher spring, not shown be twisted by about 30 °. In this case, an arm of the follower 9 engages the projection of the latch tail 6 to withdraw the trap.

It is also possible, by means of a change operation, the case 5, 6 withdraw. For this purpose, an existing from sections 39 and 40 variable length change lever is provided. The lower change section 39 of the in Figures 1 - 12 illustrated embodiment has a bend 39 ', against which the cam 21 can occur when the latch 7, 8 has its back-closed position. An angled portion 39 "remote from the bend 39 'forms a stop for a connecting piece 41 in the form of a pin, which is guided by means of a guide projection 41' into a slot guide 45 of the lock cover 2. The lock bottom 4 has a slot 46 corresponding thereto a grub screw in the connector 41 can be screwed.

The upper portion 40 of the change has a circular cut-out and is inserted in the connecting piece 41. The grub screw acts on it, so that the connecting piece is clamped on the upper exchanging portion 40. The upper interchangeable portion 40 engages a bearing ring 42, which engages with an extension on the projection of the latch tail 6 to retract the trap.

The fastening of the lock bottom 3, 4 with the forend is done via the lock bottom 3, 4 formed bends 27, the Einschrauböffnungen 28 form for screwing in fastening screws 26, the mounting holes 25 of the forend 22 pass through.

In each case at the two ends facing away from each other, the forend 22 has two Anschrauböffnungen 29, which have an elongated shape. Through this Anschrauböffnungen 29 screws can be screwed through be to secure the forend 22 with it attached lock housing in a plug-in opening of a room, building or apartment door.

Like that Fig. 3 and 4 can be seen, the first embodiment has a two parts 1, 2 existing castle ceiling and a two parts 3, 4 existing castle floor. The two castle deck parts 1, 2 and the two castle floor parts 3, 4 are made of stamped and bent parts. There is an upper lock cover part 1, which corresponds to an upper lock floor part 3. The two upper parts 1, 3 form the bearing opening 19 for the follower 9. Each of the two long hole tabs 14 has a slot 15. The long hole tabs 14 engage under the lower lock cover part 2 and lower respectively. From the upper lock cover part 1 and from the upper lock bottom part 3 each protrude a long hole tab 14 in the direction of the lower lock cover part 2 and lower lock bottom Lock bottom part 4, so that in a mounting opening 16 of the lower lock cover part 2 and in the lower lock bottom part 4 inserted fastening screw 17, the slot 15 passes through. The threaded portion of the fastening screw 17 can be screwed into an internal thread of a Befestigungsböckchens 18. By tightening the fastening screw 17, the long hole tab 14 is clamped between Befestigungsböckchen 18 and underside of the lock cover part 2 and Schlossbodenteils 4. The two lock cover parts 1, 2 or Schlossbodenteile 3, 4 are then zug- and shear-resistant connected to each other in a presettable distance position.

Since the lower lock housing part, which is formed by the lower lock cover part 2 and the lower lock bottom part 4, the latch 7, 8 and the Profilzylindereinstecköffnung 12, by moving the two housing parts 1, 2; 3, 4, the distance E ₁ , E ₂ between the follower axis 11 and key rotation axis 13 are set. In the Fig. 1 are the two castle roof parts 1, 2, or Schlossbodenteile 3, 4 in touching contact each other. Here the minimum distance E ₁ of 72 mm is set. In the in Fig. 10 1 and lock bottom part 3 each have a distance A from the other lock cover part 2 or other lock bottom part 4, so that here the distance has increased to the dimension E ₂ of, for example, 92 mm. The dimensions are given by way of example only. Of course, the dimension E ₁ can also be less than 72 mm and the dimension E ₂ can of course also be greater than 92 mm. It can also be set intermediate dimensions.

Simultaneously with the displacement of the two housing parts extends or shortens the change 39, 40. For this purpose, the grub screw 44 must be solved in the connector 41. The grub screw 44 is tightened again after the change in length from the dimensions E ₁ to the dimension E ₂ and the dimension E ₂ to the dimension E ₁ or to any intermediate position, while the connector 41 must be in abutment with the bend 39 ".

Regardless of the variation of the distance E ₁ , E ₂ , the distance from case head 5 to bolt head 7 can be adjusted. For this purpose, the faceplate 22 is exchanged for a differently shaped forend, in which the distance from trap window 23 to latch window 24 is different. Since the latch 5 is slidably seated on the latch tail 6 in the extension direction of the cuff 2, it can also be mounted in a latch window 23 arranged at a different location.

The lock can not only be adapted on site to the distance specified by the fitting plate on the door. The lock can also be adapted to the specified by the arrangement of the fitting plate on the door broad side backset. Due to its narrow design, the lock housing can also be used in a tubular frame. For varying the backset of a minimum backset D ₁ , as in the Fig. 1 is shown on an enlarged Dormaß, as for example in the Fig. 10 D _{2 is} shown, Distanzböckchen 30 are provided. The Distanzböckchen 30 have openings for the Stulpbefestigungsschrauben 26 and lie between the back of the forend 22 and formed by the two Schlossbodenteilen 3, 4 angled 27, which carry the threaded holes 28 for screwing the mounting screws 26th

It is also possible to further increase the backset by stacking a plurality of studs 30.

That in the FIGS. 13 to 22 illustrated second embodiment relates to a lock, in which also the distance can be set essentially freely only by replacing the forend. In addition, the backset can also be varied by using Distanzböckchen 30 here.

In this embodiment, the upper lock cover part 1 has two parallel extending, each cranked long hole tabs 14 which engage under the lower lock cover part 2 and have slots 15 through which fastening screws 17 can be inserted.

Also, the castle floor is divided into two in this embodiment. An upper lock floor part 3 carries the latch tail 6 and the nut, as well as a Befestigungsböckchen 51 and forms a single long hole tab 14.

The lower lock bottom part 4 forms a shaped part 49, which is designed as a zinc die-cast part and which has recesses in which the bolt is guided. Again, a change is provided, which consists of a lower change section 39 and an upper change section 40. The two changing sections 39, 40 are formed here as stamped and bent parts and are coupled together by a spring clip 50. The spring clip 50 has a U-shape and embraces the end of the lower change section 39. One of the two U-legs is extended and carries a pin 50 ', which penetrates two mutually aligned bores of the changing sections 39, 40. In the Fig. 18 Two holes are shown, which correspond to the standard distances of 72 mm and 92 mm. In a variant, it can be provided that the changing sections 39, 40 have a multiplicity of holes lying close to one another, so that an almost stepless adjustment of the exchangeable length is possible.

The adjustment of the backset D ₁ , D ₂ , also takes place in this embodiment by means of Distanzböckchen 30. The latter have on their forend 22 indicative rear sides recesses 30 'and on their front facing thereof form-adapted, spaced-apart lugs 30 " are positively stacked on top of each other to adjust the backset.

The attachment of the Distanzböckchen 30 on the lock housing is on the one hand to the above-mentioned Befestigungsböckchen 51 in the upper housing part. The Befestigungsböckchen 51 forms to the lugs 30 'corresponding recesses 52. Also, the molding 49 has a plurality of fastening points, each having recesses 53 for the entry of the lugs 30 'of the Distanzböckchen 30.

The upper lock bottom part 3 is formed in this embodiment as a stamped and bent part and has a Anschraublasche 27, which is formed by a bend. The Anschraublasche 27 has a material thickness which is sufficiently low, so that the Anschraublasche between the two projections 30 'fits.

At the in Fig. 23 - 33 illustrated embodiment are used to change the backset spacer strips 55, 56. The spacer strips extend over the entire length of the lock body in the pushed apart position, as in Fig. 23 is shown. The Fig. 23 shows the use of two differently trained spacer strips 55, 56. If necessary, but only one of the two spacer strips 55, 56 needs to be used. The Fig. 23 moreover shows a guide piece 60, which is arranged between the first spacer bar 55 and the forend 22. From the Figures 24 . 27 . 28 and 32 the use of the guide piece 60 can be seen. The guide piece 60 has a case passage opening 61 through which the trap 5 can pass. The trap window 32 of the forend 22 has a greater length than the case passage opening 61. The guide piece 60 forms a projection 62, which protrudes into the trap window 23 as a filler. The trap window 32 of the faceplate 22 can thus be reduced by inserting the filling piece 60 in the direction of extension of the cuff.

In order to change the position of the latch 5 with respect to the latch 7, the guide piece 60 can be reversed. In the in Fig. 24 shown operating position is the filler 62 between the case 5 and latch 7, so that here the case 5 has the greatest possible distance to the latch 7. In the in Fig. 32 Here, the guide piece 60 is in a reversed position, so that the filler protrudes 62 above the case 5 in the case passage window 23.

The two spacer strips 55, 56 each have one of the material thickness of the filler 60 corresponding recess 63 and rearward a projection 64. In the recess 63 of the spacer bar 55 projects the projection 64 of the spacer bar 56th

That in the FIGS. 23 to 33 illustrated embodiment also has a housing shell 67 which is formed by a stamped sheet metal part. The housing jacket 67 is bent around its longitudinal edge to a U-shaped piece, wherein a short housing narrow wall 73 is formed, which is formed by two superimposed housing tabs. These do not need to be firmly connected. The housing jacket 67 is merely pushed over the upper housing part and is held there by means of fastening pins 68 which reach into fastening openings of the housing jacket. The housing shell 67 further has an opening 71 for pushing through the pusher and another, rectangular opening 69 through which the user can insert an operating tool, such as a screwdriver, to release the mounting clip 50, so that the pin 50 'of a bore 54th can be moved into another hole 54. The housing shell 67 also has an extension 70 which extends over the back of the lower housing part.

The mortice locks described above are universally applicable and adaptable to the particular conditions on site. They are therefore particularly suitable as parts of an emergency kit, which has a variety of differently shaped cuffs with associated locking heads 7 and 5 case heads. These different latch heads 7 and latch heads 5 can be connected to the various cuffs with a single lock case. Nevertheless, all common distances E ₁ , E ₂ and common mandrel dimensions D ₁ , D ₂ , can be set. For the called for on-site repair locksmith thus eliminates the need to provide a variety of different dimensions having locks or the need to take first measure on site, and then to obtain the appropriate lock.

All disclosed features are essential to the invention. In the disclosure of the application is hereby also the disclosure of the associated / attached Priority documents (copy of the prior application) fully incorporated, including for the purpose of including features of these documents in claims of this application.
