Cl. 70-363 6 Claims ABSTRACT OF THE DISCLOSURE A cylinder type lock having a unitary body defining a cylindrical hole therein, a splined key entry channel inserted in each end of said hole, splines on said body projecting into said hole and engaging said splines on said key entry channels, a slotted barrel in each said key entry channel and rotatable therein by means of a key, a tumbler slidable in each of said barrel slots, a pair of crenulated washers fixed in said hole by engagement of said crenulations with said splines on said key entry channels and said body splines, a catch member located between said barrels, and a rectangular member associated with each barrel and adapted to couple said barrel with said catch member on insertion of said key in said barrel.
Cylinder locks are known of the type comprising socalled safety tumblers, which are expensive in view of the difliculty of making their numerous constituent parts. These devices are by no means thief-proof and the number of their possible combinations is limited. Moreover, for asymmetric models of such cylinder locks it is necessary for the manufacturer to produce cylinders with left and right handed parts depending on the doors to which they must be fitted.
It is an object of the present invention to overcome these disadvantages in a simple and efficient manner.
The cylinder itself comprises in combination, a socket for the door latch, a drive ring and a locating screw, allowing the said catch to be reversible in the lock body according to the direction of opening of the door desired. Gudgeon pins are disposed radially in the key aperture to render the lock more thief-proof, together with a sixth tumbler which increases the number of key combinations. Alternatively this sixth tumbler may be omitted and replaced by at least one radial pin with a view to the use of a master-key.
The invention will be further described with reference to the accompanying drawings, in which:
FIG. 1 is a longitudinal section taken along the line I-I of FIG. 3, of a reversible cylinder lock according to the invention, with six palettes;
FIG. 2 is a longitudinal section taken along the line II in FIG. 3 of a part of a cylinder lock according to a second embodiment of the invention;
FIG. 3 is a transverse section along the line II-II in FIG. 1;
FIG. 4 is a perspective view of the rectangular member;
FIG. 5 is a perspective view of an elongated operating part utilized in the case of extra long cylinder locks;
FIG. 6 is an exploded perspective view of a washer, the lock bore, and a part of the lock body showing the method of assembly of these three pieces.
From FIG. 1 it will be seen that the cylinder lock comprises a body 1 formed in one piece (cut from a solid bar). A key 2 is inserted into the barrel 3, in such a manner as to move the six tumblers, such as 4 and 5, so that their code slots are opposite corresponding orifices in two half- washers 6 and 10, thus enabling rotation of the key in said barrel 3 to be effected. The two halfwashers 6 and are fixed in grooves in the barrel and are aligned with the grooves of the key channel 7 (FIG. 6), the transverse pins 8 fixing the said channel 7 in the body 1. When the key 2 is inserted, it forces the rectangular member 9 into a corresponding orifice in the ring 11, which is of such a diameter as to fit the cylinder bore. The ring 11 transmits the rotational movement of the key 2 to the door latch 12 by means of a screw 30. During movement of the key in the direction 14 the sprung rectangular member 9, by being introduced into the driving member 11, displaces a pin 16 which disengages a similar member 17 with spring 15 from the driving member 11.
The other cylinder end carries a barrel 19 analogous to barrel 3, two half- washers 20 and 24 analogous to the two half-washers'6 and 10, a key channel 21 analogous to the channel 7 anda sixth tumbler 25 analogous to the sixth tumbler 4 which includes an embedding hook 18.
The gudgeon pins 26 and 27 disposed radially in each entry channel of the cylinder lock, prevent interference with the look by means of a hand drill. The latch support 13 of a standard lock is of normal length, but is made longer by an insertion 28 if the lock cylinder itself is elongated.
In FIG. 2, the lock is drawn without the key so as to show the gudgeon pin 23 mounted radially in the barrel 19 to permit the use of a master-key, since only a key having a groove corresponding to this pin can be introduced completely so as to bring the tumbler gaps to their correct positions to allow rotation of the barrel. The key channel 21 is fixed in the body 1 by a screw 22 inserted into the said body 1.
In FIG. 3, the rectangular member 9 is shown introduced into a corresponding slot 29 in the ring 11 which is joined to the latch 12 by a screw 30, the end 31 of the screw being located in a slot 32, after traversing the sup port 13 of the catch. If the lock is to be operated from the other end, the screw 30 must have its end 31 placed in the slot 33. Whatever the direction of opening of the lock, the rotation of the key 2 and the barrel 3 or 19 will rotate the rectangular member 9 or 17 disposed in engagement with the ring 11 to ultimately rotate the latch 12 secured to ring 11 by screw 30.
In FIG. 4, a rectangular member 42 similar to members 9 and 17 is shown in perspective and is provided with a shank 43 about which a return spring (not shown) may be mounted.
In FIG. 5, the driving extension ring 11, of a length corresponding to the length of the lock, comprises 2 longitudinal slots 32 and 33 which determine its position in the body of the door latch. According to the direction of opening of the lock, one of the two slots 29' or 35, may be located in the position key introduced in the position allowing opening. The bore 34 receives the pin 16 (FIG. 1).
In FIG. 6, the channel 7 comprises splines such as 36; the washer constituted by the two half- washers 6 and 10, is cut externally in a crenulated manner to the same dimensions as the splines of the channel 7, slots such as 37 of the washer 6 being adapted to receive the tumblers 5. The body 1 comprises further splines 38 which are dimensioned similarly to the splines 36. During assembly the two half- washers 6 and 10 are slid along the splines of the entry channel 7 until they reach the face 41; thereafter, this sub-assembly is pushed into the splines of the body 1, until the washer comes into contact with the face 39. The entry channel 7 is axially immobilized in the body 1 by the end of the screw 22 of FIG. 2, and the washer is immobilized by enclosure between the two faces 41 and 39 which are themselves fixed.
We claim:
