Definitions

  • the present invention relates to the field of locksmithing and it relates, more particularly, to locks of the type with double barrels or cylinders comprising a single locking member which can be controlled from either side of a movable panel, such as a door, on which said lock is mounted.
  • Such locks are widely known and include two cylinders containing two barrels each delimiting an inlet channel in which are arranged movable members which it is advisable, by means of a key, to ensure alignment to release rotation of the barrel relative to the cylinder.
  • movable members can be pistons, pumps and counterpumps, flakes or the like, associated with springs and well known in the art.
  • a body made of any suitable material, generally a metal alloy.
  • the body comprises a cylindrical part for receiving the barrels and a radial extension part or tail which is, most often, reserved for the placement of pistons or the like.
  • Such a body is most often produced by machining as regards the cylindrical housings of the barrels, which are coaxial and separated by a clearance reserved for the passage of the common locking member.
  • Such a production method which can be described as traditional, has been used for many years but is currently experiencing a limit, due to its production cost. It is, in fact, necessary to use a solid profile which must be largely machined, which represents an unnecessary loss of raw material, generally expensive. It is, moreover, necessary to carry out a certain number of operations of machining by recovery, which increase the cost of production.
  • a proposal made, in particular, by the patent may be considered GB 1,581,095 which recommends making two half-bodies each comprising a cylinder extended by a tail joined to that of the homologous body by a pinned key.
  • Such a manufacturing method eliminates, in part, the delicate machining operations, since the definition of the cylinders and of the housings internal to the latter is determined by slice at the level of each flange.
  • the barrels are arranged in a conventional manner and therefore do not offer resistance compatible with the levels required by the new current safety standards.
  • the object of the present invention is to remedy the above drawbacks by proposing a new technique for constructing a cylinder lock, with rotary barrel and with double entry, making it possible to facilitate machining operations, to reduce the cost of these and lead to a functional unit offering better resistance to the tensile and / or rotation forces imposed on the barrels contained in the cylinders.
  • Fig. 1 is a sectional elevation of a lock according to the invention.
  • Fig . 2 is a cross section taken along line II-II of FIG. 1 .
  • Fig. 3 is a perspective view showing, in more detail, the conformation of one of the constituent elements of the lock.
  • FIGS. 4 and 5 are views similar to FIGS . 1 and 2 , but corresponding to an alternative embodiment of the subject of the invention.
  • the lock with two cylinders and double entry consists of two sub-assemblies 1 a and 1 b which are symmetrical with respect to a plane P-P ' considered to be transverse to the axis of symmetry x-x' of the assemblies 1 . Due to the character of symmetry, the following description is made only in relation to one of the subsets, such as the subset 1 a , it being understood that the same references, assigned the index b , denote the same constituent elements of the sub-assembly 1 b .
  • the sub-assembly la comprises a shell 2 a delimiting a cylinder 3 a which is open at its two ends and whose axis coincides with the axis x-x ' .
  • the shell 2 a is extended, from its outer face, by a radial bar 4 a which extends beyond the shell 2 a by defining, by its face facing the axis x-x ' , a segment 5 a concave wall centered on the axis x-x ' and materializing an extension of the outer peripheral surface of the shell 2 a .
  • the cylinder 3a is occupied by the low-cut part 6 has a bushing 7 has cylindrical, tubular, which is centered or indexed in the shell, through a pin 8 is engaged in a hole 9a of the bar 4 has to protrude partly within an open slot 10 presented by the sleeve 7 has from its transverse edge opposite to the shell 2 a.
  • the axial engagement position of the sleeve 7 a inside the cylinder 3 a is determined by a shoulder 11 a formed in the border area of the low-cut part 6 a and intended to cooperate with the corresponding edge 12 a of the sleeve. 2 a .
  • the axial immobilization is conferred by a second reference formed by a shoulder 13 is supported against an abutment flange 14 a which is presented by the peripheral wall of the cylinder 3a, in the plane of the front panel 15 a of the shell 2 a .
  • the socket 7 a defines a cylindrical housing 16 a which is reserved for mounting a locking mechanism 17 a constituted by a barrel internally containing movable members 18 a , generally associated with elastic return members and delimiting a nut 19 a d engagement of a key whose profile corresponds to the structural and dimensional characteristics of the mechanism.
  • the follower 19 a is formed coincident with a front or entry opening 20 a opening on the face 15 a .
  • the movable members 18 a are constituted by axial sliding pumps, the lengths of which are determined, as a function of dimensional coding, in relation to the axial fins presented by the key.
  • the notches, such as 21a, presented by the various moving elements 18a can be simultaneously supplied in connection with a Foncet or the like 22 having a piston engaging cutouts to ensure, in the rest state , the angular immobilization of the barrel 17 a inside the cylindrical housing 16 a .
  • a driver 23 which is common to the barrel 17b.
  • the driver 23 supports a bit 24 angularly immobilized and provided with a bolt 25 constituting the locking member of the lock.
  • the bit 24 is mounted between two centering rings 26 a and 26 b , closing the corresponding open ends of the sockets 7 a and 7 b and responsible for delimiting between them and in alignment with the corresponding faces of the bars 4 a and 4 b , a clearance 27 in which the bolt 25 can rotate.
  • the closure and centering rings 26 a and 26 b ensure the immobilization of the barrels 17 a and 17 b against the nuts 19 a and 19 b of the sockets 7 a and 7 b .
  • each sub-assembly 1 can comprise in addition a locking system Annex 28a extending in a radial direction in the strip 4 and through the bushing 6a and the barrel.
  • the system 28 has a die 29 includes a through and partly engaged in the barrel.
  • the die 29 a is biased, by a spring 30 a , to push a pin 31 through the barrel to project into the nut 19 on the path of the heel of the control key.
  • the system 28 allows a rotation of the cylinder 17 a when, as a result of the engagement of the key, the interface between the die and the pin is aligned with the cylinder 16 a.
  • locking mechanisms differing from the above description can also be mounted in the cylindrical housings 16 a and 16 b .
  • the bars 4 a and 4 b of the two shells 2 a and 2 b are joined by a beam 32 which comprises two tenons 33 a and 33 b engaged in open mortises 34 a and 34 b presented by the bars 4 a and 4 b between the edge 12 a of the corresponding shell and the hole 9 a for receiving the pin 8 .
  • each tenon 33 is calculated so that, after engagement, the terminal part protrudes from the face 5 a or 5 b and is thus engaged in an oblong opening 35 a , 35 b presented by the socket 7 a , 7 b and aligned with mortise 34 a or 34 b via the indexing pin 8 a or 8 b .
  • the height of each post is also calculated, as shown in fig . 2, so that after complete engagement, the transverse end surface or a flat surface 36 a or 36 b, that each pin constitutes a kind of pile or abutment firmly coming to bear under the corresponding Foncet 22 a or 22 b.
  • connection is completed by the installation of transverse pins 37 a , 37 b passing through the bars 4 a , 4 b and the pins 33 a , 33 b .
  • the structural assembly makes it possible to constitute the lock from two sub-assemblies 1 a and 1 b which can be produced separately and easily by conventional machining operations requiring only minimum recovery phases, due to the immediate accessibility to each of the transverse faces, either of the shell, or of the socket, or of the beam.
  • the selected assembly allows for an axial support of the sleeve particularly resistant against the shell, through flanges 11a and 13a and through cooperation with the pin 33 which passes through the sleeve.
  • Such an assembly also makes it possible to establish a particularly resistant angular connection, by means of the bolt bearing on the pile 36 that each stud constitutes, by the engagement of the latter inside the lumen 35 and by the intermediate of the centering-indexing pin 8 .
  • the shell 1 is firmly immobilized on the beam 32 by the engagement of the stud 33 and by the transverse connection established by the pin 37 of large section.
  • the beam 32 having a very thick section, establishes a particularly resistant connection between the two sub-assemblies.
  • FIGS . 4 and 5 An alternative embodiment is illustrated in FIGS . 4 and 5 according to which the pins 31 a and 31 b are constituted by independent elementary parts which are mounted, by means of transverse pins 41 a , 41 b in blind mortises 42 a and 42 b formed in the beam 30 .
