Description

The invention relates to a lock, in particular glass door lock with arranged between a lock bottom and a lock cover of a lock housing by turning a follower and / or a key operable closure elements and projecting from the outsides of the lock bottom and lock cover positioning for entry into positioning of a fitting mounting plate.

Such a lock is known in the market. So revealed, for example FR 2 135 405 A1 such a castle. Pin-shaped positioning projections are welded onto the outwardly facing broad sides of the lock bottom and the lock cover. These positioning projections are inserted in the mounting of the lock on a glass door in positioning holes of fitting mounting plates. The housing of the glass door lock lies with one of its two broad side surfaces with the interposition of a rubber mat directly on the broad side of the door leaf forming glass plate. The glass plate has two openings, one for the passage of the square mandrel of a pusher handle and another for the passage of a lock cylinder. A first fitting mounting plate is located on the opposite side of the castle wide side of the glass plate. This fitting mounting plate has insertion portions which protrude into the openings of the glass plate and which form the positioning holes into which the positioning pins are inserted. On the side facing away from the glass broad side of the lock housing, a further fitting mounting plate is mounted, which also has positioning holes into which protrude the positioning pins. The two plates are screwed together with the help of the glass plate and the lock housing protruding mounting screws. On the fitting mounting plates then the screens are placed, which give the castle its appearance.

The invention has for its object to improve the generic lock assembly technology with simple manufacturing technology.

The object is achieved by the invention specified in the claims, wherein initially and provided essentially that the positioning projections, which may be formed as positioning pins as in the prior art, openings of the castle floor or the castle ceiling by cross-extensions of a between castle floor and Castle ceiling arranged spacer element are. This spacer can be formed by a plastic molding, such as a plastic injection molded part. This plastic molding is located between the castle ceiling and the castle floor so that it completely fills the gap between the castle ceiling and the castle floor. The spacer thus forms mutually away facing support surfaces on which the inner walls of the castle ceiling or castle floor can be supported. From these support surfaces protrude in the immediate opposite position on both sides of the positioning pins. They penetrate the said recesses of the lock cover or the lock floor and engage in the mounting of the lock in the positioning of the respective fitting mounting plates. When tightening the fitting fastening screws, a clamping force is formed, which is intercepted by the spacer elements according to the embodiment of the invention. A deformation of the castle floor or castle ceiling is thereby effectively prevented. It is advantageous if, in addition to the positioning pins, the spacer element also forms eyes, in particular in the form of bores, through which the fastening screws can pass. The eyes are preferably formed by holes in Stützböckchen. The Stützböckchen sitting materially connected to each other at the ends of the preferably U-shaped spacer element. In a preferred embodiment of the invention protrude from the support surfaces of the Stützböckchen away from each other facing sleeve-shaped Extensions. The latter form the ends of the holes and have an outer diameter which fits into Befestigungsschraubendurchtrittsöffnungen of castle floor and lock cover. In a preferred embodiment, the lock has two or more spacer elements. A first spacer surrounds the pusher in regions. The arranged at the ends of the spacer element eyes are diametrically opposite relative to the axis of rotation of the follower. The two eyelets forming the eyes are connected by a material web from which the positioning pins originate. This web can also form a bulge, which is associated with a further Befestigungsschraubendurchtrittsöffnung, which is located in the assembled state of the castle below the follower. A second spacer element is spatially associated with a passage opening for a latch actuator. The locking actuator is preferably a lock cylinder. It can also be a nut. Also, this spacer element is designed substantially U-shaped and has two arranged at the ends of the U-legs blocks, which are each provided with eyes through which the fastening screws can pass. Again, the above-mentioned sleeve-shaped extensions are provided which can protrude into fitting screw passage openings of the castle floor or the castle ceiling.

The lock according to the invention has a lock housing which has a lock bottom 1 made of sheet metal and a lock cover 2 made of sheet metal. In the housing formed by the lock bottom 1 and lock cover 2 is a case 3, which projects through a passage window of a forend 26 with its case head and is held by a latch spring in a forward position.

In two aligned openings of lock bottom 1 and lock cover 2 a follower 5 is mounted, which has a square opening for the passage of a square mandrel of a handle 34. A projecting from the follower 5 nut arm 5 'engages the latch tail 3' of the case 3 to them to withdraw from the closed position. In addition, a change lever 25 engages the latch tail 3 'in order to retract the latch 3 by actuating a lock cylinder.

A bolt 4 mounted in the lock housing has a bolt head, which likewise projects through a window of the forend 26. The bolt tail carries a tumbler 24, which holds the latch 4 in the back-closed or pre-closed position.

An unillustrated lock cylinder can be inserted into the lock cylinder insertion opening 23 and rotated by inserting a matching key. In this case, the closing member, not shown, lifts the tumbler 24 to move the latch 4. In addition, by turning the closing member in the locked-back latch position in the opening direction, the change lever 25 can be pivoted to retract the latch 3.

How the particular FIG. 3 can be seen, the lock has a first spacer element 6, which in the FIG. 6 is shown enlarged. This spacer consists of a plastic injection molded part and has a substantially U-shaped configuration. To U-space of the spacer element 6 supports the follower such that two arranged at the leg ends eyes 10 are relative to the axis of rotation of the follower diametrically opposed. The two eyes 10 are formed by Stützböckchen 41, which form mutually away facing support surfaces 11, against which rest the inner sides of the lock bottom 1 and lock cover 2. The two Stützböckchen 41 are connected to a web 42 with each other, which has the said U-shape. From the support surfaces 11 of the web 42 protrude positioning pins 7. In the same direction protrude from the end portions of the spacer 6 sleeve sections 12, which form the ends of the eyes 10 forming holes. In the assembled state, the sleeve sections 12 engage in fitting screw passage openings 21 of lock bottom 1 and lock cover 2. The positioning pins 7 extend through aligned openings 8, 9 of lock bottom 1 or lock cover 2. The positioning pins 7 have such a length, that they protrude in the mounted state on the broad side planes of the housing.

There is provided a second spacer element 14, which is also formed by a U-shaped plastic injection molded part. This spacer 14 also forms two positioning pins 15 pointing away from each other. As well as the spacer element 6, the positioning pins 7, 15 are formed by a uniform, substantially cylindrical body, which is integrally formed on a web of the spacer element 6, 14, the end-side blocks together.

In the second spacer element 14, the two end Böeckchen 41 are in relation to an opening portion of a Schließzylindereinstecköffnung 23. Again, the facing away from each other edge sides of the web 42 and the blocks 41 support surfaces 19, in which the insides of the castle floor 1 and castle ceiling 2 can support. From the support surfaces 19 spring sleeve sections 20, each forming an end of a bore 18 for the passage of fitting mounting screws 31. The sleeve sections 20 engage in the assembled state in Befestigungsschraubendurchtrittsöffnungen 21 of lock bottom 1 and lock cover 2 a. The positioning pins 15 engage through mutually aligned openings 16, 17 of lock bottom 1 and lock cover 2, so that they protrude over the housing broad sides. Here a recess 43 is provided for the passage of a forend screw.

The lock according to the invention can be mounted on a glass door, as it Figures 2 . 8th . 9 and 10 demonstrate. With the interposition of a rubber mat 32, the lock is fastened with one of its two broad sides to a glass plate 38 of a full-glass door. The glass door has two openings 39, 40 for the passage of the square section of the handle 34 and the lock cylinder.

A fitting mounting plate 27 mounted on the broadside opposite the lock has a plug-in portion 30 and a sleeve extension 33, each projecting into an opening 39, 40. The sleeve extension 33 and the insertion section 30 form positioning openings 29 into which the positioning pins 7, 15 can be inserted.

A second fitting mounting plate 28 is mounted on the side facing away from the glass sheet 38 wide side of the lock housing. Also this fitting mounting plate 28 has positioning holes 29, in each of which a positioning pin 7, 15 protrudes.

The two fitting mounting plates 27 are connected to each other with a total of four fastening screws 31, wherein in the FIG. 9 only two fastening screws 31 are shown. The fastening screws protrude through the fitting screw passage openings 21, 22 or the eyes 10, 18.

The lock or the fitting mounting plates 27, 28 are clad with screens 35, 36, which are fastened with fastening screws 37 on the forend 26 or otherwise.

In an alternative embodiment, not shown, a further fitting screw passage opening 22 can be used for attachment, which is surrounded by a bulge 13 of the spacer element 6. <B> LIST OF REFERENCES </ b> 1 Castle grounds 2 lock cover 3 Cases 3 ' catch tail 4 bars 5 follower 5 ' Drückernussarm 6 spacer 7 positioning 8th opening 9 opening 10 eye 11 support surface 12 sleeve section 13 bulge 14 spacer 15 positioning 16 opening 17 opening 18 eye 19 support surface 20 sleeve section 21 Mounting screws through opening 22 Mounting screws through opening 23 Schließzylindereinstecköffnung 24 tumbler 25 change lever 26 stulp 27 Fitting mounting plate 28 Fitting mounting plate 29 position opening 30 insertion section 31 fixing screw 32 Rubber Liner 33 Sleeve extension 34 trigger handle 35 modesty panel 36 modesty panel 37 fixing screw 38 glass door 39 opening 40 opening 41 Stützböckchen 42 web 43 recess
