Description
1 30767~
The invention relates to a device for securing a rotary lock cylinder which is inserted -through a lock case wherein a first hard metal body surrounds -the rotary lock cylinder outside the door.
German Patent No. 1,289,454 discloses a rosette for cylinder ]ocks which is made of solid material, is encased into the door panel and bears against the lock case. This rosette fails to provide sufficient protection since it can be gripped with a suitable tool and the rotary lock cylinder can be twisted off at its weakest point. The weakest point in this cylinder is at its center since, below the catch, a por-tion is removed to provide a channel for the catch and the remaining part of the cylinder is lS s-till further weakened by providlng a threaded bore for the flange screw.
~ erman OS 26 09 647 proposes a reinforcing plate to secure insert locks having double cylinder lock inserts. This plate ls placed in an in-ternal recess provided in a wooden door and is permanently connec-ted to the lock cover. This rotary lock cylinder is ~lso secured, in generally known manner by means of a Elange screw. The dlsadvantage is that the plate woulcl be very difficult to fit and would not provide sufficient protec-tion against a forcible entry. Here again, the rotary lock cylinder is weakened by the threaded bore provided for the flange screw. The latter is needed in this particular situa-tion since it serves to draw the cylinder against the edges of the cylinder cut out provided in the lock case and thus enables to mount the cylinder.
In the case of a lock with a very long flange screw, the latter is poorly guided in the lock and does not secure it even if i-t is screwed very thightly. The cylinder is easily displaced by slamming the door or as a result of a faulty operation. If the cylinder 1 3û7674 is displaced, the catch rubs against the lock plate and considerable force is required to turn the key and open the lock. The cylinder must be recentered and adjusted. It is known that there are many doors in which the lock and the pressure fitting provided with a long shield is not properly fitted and can never be fixed by tightening -the flange screw.
It is an object of the present invention to provide a device of the type mentioned above which will overcome the aforementioned disadvantages and which, in spite of this can easily be mounted and produced.
It is also an object of the present invention to provide a lock case and a rotary lock cylinder which are particularly suitable for this device.
These and other objects according to the invention may be achieved by providing a device for securing a rotary lock cylinder which is inserted through a loc]c case in which a first hard metal memher surrounds the rotary loc]c cylinder outside a door, wherein the hard metal member rests against the lock case to be secured thereto, means enabllng said hard metal member to cover at least in part the front of said rotary lock cylinder in relation to said lock case; the device also comprising a second hard metal member mounted inside -the door and surrounding the internal section of the rotary lock cylinder.
Tests hava shown that the first hard metal member can easily pro~ect from the fitting and still cannot be torn out. This eleminates the need for costly long shields and for the flange screw and the weaknesses they cause in the lock cylinder are thereby avoided. In spite of this, correct and :: :

permanent centering of the cylinder lock is assured.
Forcing or drilling out the lock cylinder are largely prevented.
In order to prevent the rotor from being forced through, the first hard metal member may comprise a rotatable cover provided with a slot for inserting a key therein, mounted in an opening in front of a rotor. The cover is supported on the lock case by means of a slit sleeve.
A simple way of obtaining a continuous cen-tering of the rotary lock cylinder and of securing it axially in the lock case, is to provide a centering element which engages the lock cylinder and is supported on the lock case by means of an adjusting screw.
Accorcling to another embodiment of -the invention, the Gpening in the lock case through which the rotary lock cylinder is inserted, is made wide enough in the upper area to permit lock cylinders of cdifferent siæes to be inserted therein. This has the advantage that rotary lock cylinders of different sizes may be used, thus greatly simplyfing stock ]ceeping.
Another advantage of the device according to the invention is that the rotary lock cylinder need no longer be coloured since it is wholly or partly covered by a bushing or bushings.
In accordance with another particularly advantageous embodiment of the invention there is provided a Swiss type of rotary lock cylinder wherein the cylinder holder is reinforced with an axially running screw which projects at both ends of the cylinder holder and is used to axially align the rotary lock cyiinder.

The inven-tion will be better illus-trated with reference to the annexed drawings, which are not intended to limit the scope of -the present invention and in which, Fig. la is a partial cross-section through a door panel provided with an insert lock and a device according to the invention, Fig. lb is a partial view in the direction of arrow lb shown in Fig. la;
Fig. 2 is an exploded view of the device illustrated in Figs. la and lb, according to the invention;
Fig. 3 and 4 are exploded views of two variants of the invention;
F`ig. 5 is a partial view of a lock case;
Fig. 6 shows a third variant of a device according to the invention and a double lock cylinder, also in exploded view;
Fig. 7a shows a base with inserted pins;
and Fi~. 7b is a vertical section taken along line VII-VII oE E'ig. 7.
Fig. la shows a door 24 into which an insert lock 45 is inserted in known manner. Whereas the internal arrangement of this lock is con-ventional, according -to Fig. 5 face plate SO differs in that no bore is needed for a flange screw disposed below the latch 53. A double rotary lock cylinder 1 is inserted into a through hole 46. The shape of the through hole mus-t match that of the lock cylinder and it is preferably wide enough to accomodate lock cylinders of different shapes. The lock cylinder comprises in known manner, between an outer cylindrical part 3 and an inner cylindrical part 4, a catch 2 by means of which the latch may be pushed in the lock case.
,.. . .
A solid sleeve 8, preferably made of hardened steel, is placed over outer cylindrical part 3. The sleeve 8 comprises a recess 52 into which a sleeve 13, also made of hardened steel, is inser-ted.
Sleeve 13 is adapted to rotate in recess 52 and comprises a slo-t 13a and a hole 55 designed in such a manner that cylindrical part 3 may be inserted into sleeve 13 with little play. The front ace of sleeve 8 comprises, immediately in front of rotor 7a, a through hole 12 into which a cover 14, made of hardened steel, is rotatably inserted from the rear side. Cover 14 is supported by sleeve 13 on lock case 45 and comprises a slot 15 through which a flat key may be Lnserted. Sleeve 13 and recess 52 are designed in such a manner that cylinder 1 is guided, with little play, along the entire length of the projecting part.
Two threaded pins 26 are screwed into sleeve 8 and extend :Ln through holes 33 provided in the lock case. The threaded pins 26 carry nuts 27 at their free ends, which enable the sleeve to be pulled toward lock case 45 and to be fixedly secured thereto. Lock case 45 is relatively thin and one or more plates 18 are placed between it and sleeve 8.
Furthermore, a pin 43 is pressed into the upper part oE sleeve 8 and engages in a hole 44 provided in lock case 45, and in intermediate plates 18. Screws 26 and inserted rotary lock cylinder 1, in combination with pin 43 prevent sleeve 8 from being moved.
A second sleeve 9 which also bears against lock case 45, if necessary by means of a plate 18 disposed -therebetween, is mounted inside door 24.
Except for the opening 11, the front of the second sleeve 9 covers cylindrical part 4. Sleeve 9 also comprises a recess 56 which corresponds to the shape of outer cylindrical part 4. This cylindrical part 4 . .
1 307 67~
is guided in recess 56. Two blind holes 28 accomodate nuts 27 and pins 26. Sleeve 9 ensures tha-t lock cylinder 1 is properly guided and that sleeve 8 cannot be moved by the use of force.
Opening 11 usually has no cover and the key can therefore be inserted here directly into rotor 7 b.
During the assembly of the device, the ro-tary lock cylinder 1 can be centered axially so as to enable catch 2 to be moved in lock case 45 without the use of clamps or fittings. For this purpose, clamping elements 16 and 17 are inserted into sleeves 8 and 9. They bear, at the bottom, against cylinder channel 5 and by means of cams 21 and 22 they are engaged in grooves 6a and 6b provided in lock cyllnder 1. Clamping elements 16, 17 have threaded holes Eormed thereln into which screws 19,20 are inserted. By turning screws 19,20, lock cylinder 1 may be displaced axially and continuously. Openings 35 arld 42 in sleeves 9 and 8 provide access to screws 20 and 19 after the sleeves have been mounted. Once lock cyl;nder 1 has been centered, a plug 41 and a screw 23 are inserted. The lock cylinder is fixedly secured in lock case 45.
Figures 3 and 4 show variants of the ad~usting device for a rotary lock cylinder la, lb of the Swiss type. Pocket 49 of loc]c cylinder la carries a continuous steel screw 47 which outwardly extends a-t both ends thereof. Sleeves 48, with continuous threaded holes, are screwed to screw 47.
30 Screws 59 and 61, which extend through sleeves 8 and 9, are screwed from the outside into sleeves 48. By turning screws 59 and 61, lock cylinder la can be moved continuously in either direction. It is essential that cylinder pocket 49 be substantially reinforced with screw 47. In the design according to Fig. 4, sleeves 64 are screwed to a similarly ,.. .. .
~ 307674 continuous screw 63, the said sl.eeves being in turn secured to clamping elements 49 by means of groove 65,66 and tongues 67,68. Pins, not shown, are screwed into con-tinuous threaded holes 57 provided in clamping elements 49. As indicated hereinbefore, these pins are used to center and ensure a proper location for cylinder 1.
During assembly, rotary lock cylinder 1 is first inserted into lock case 45 and bushings 18 are provided if necessary. Clamping element 16 is then inserted and -this is followed by sleeve 8, with inserted cover 14 and sleeve 13. Bushing 18 is secured to lock case 45 with nuts 27. Clamping element 17 is then applied to cylindrical part 4 after which sleeve 9 is mounted. Lock cylinder 1 is centered as described hereinbefore, hole 42 is closed with plug 41, and sleeve 9 is secured with screw 23.
The cylinders illustrated in F'igures 3 and 4 are assembled in the same way, except that hole 70 provided in sleeve 13 is eccentric to correspond to the position oE the rotor.
In the design shown in Figures 6 to 7b, -the hard metal member to be mounted inside the door consists of a base 8~ with a continuous recess 89 into which the inner section of rotary lock cyl'inder 1 is inserted. Access to centering element 17 is rnade poss.ible through this recess 89. In addi-tion to recess 89, the base 84 is p'rovided with four continuous holes 90 through which pins 85 extend.
These pins are screwed, at the inner end, into hard metal member 8. Each pin 85 lies with its wide head against a step 91, thus drawing the hard metal member 8 and the base 81 firmly to the lock case. The heads of pins 85 ca.rry cruciform slots 81 into whlch pins 80 may be inserted in pairs, thus preventing pins 85 from coming loose during an attempted break in.
'` ~30767~
During assembly, transverse pins 80 are placed half depth in recesses 87, they are pushed into slots 81 of the tigh-tening pins 85 and are then bent into a recess 88 a-t the free end thereof. Slots 81 provided in pin 85 are tapered outwardly so that the transverse pins 80 cannot fall out in axial direction wi-th respec-t to pinds 85. A rod like, stepped spacing elemen-t 82 is arranged below the cylinder pocket and each end is engaged in a hole 83 provided either in hard metal member 8 or in base 84. Spacing element 82 is provided in the case of lock cases in which elements 8 and 84 project -therebeyond a-t the bot-tom. The spacing element also stabillzes elements 8 and 9 and ensures that, even in lock cases of this kind, there is no way in which elements 8 and 9 can be moved or loosened in relation to -the lock cases.
Base 84 has a cover 92 which is secured by means of screws 26 to base 84 and lock cyl.inder 1.
Spacing discs, not shown, may be arranged between cove.r 92 and base 84.
The dev:ice described above ~or securing a rotary lock cylinder can therefore be centered accurately without using a flange screw. The lock is easily operated and ou-tstanding protection is provided against brutal break in me-thods such as twisting off, tearing out and core pulling.
