Description

The present invention relates to a device for locking the movement

  relative to one another, in particular for removable wall supports, cabinet doors,

  gateways of candelabra or others.

  Although more particularly developed for such applications, it can also be used in all sectors of the economic activity in which it is desired to block access and / or

  prevent disassembly of an element and / or installation.

  Currently, particularly in the field of urban shelters, it is necessary to meet walls, usually made of ice, subject to a fixed frame. Such installations being regularly the subject of vandalism, said windows are often damaged and / or

  fractured, and must be easily changed.

  Thus, until now their fixation was easily accessible and little or poorly protected, facilitating the work of potential thieves attracted by their

pecuniary value.

  Indeed, given their size and the quality of the materials used to make them, said ice creams are generally of a

high cost.

  Such installations therefore need to be locked. For this, many different mechanical devices are known. However, in such a context, they are, in most cases, either too expensive or not reliable enough and the facilities on which they are employed are then easily forced. The object of the present invention is to provide a device for locking the relative movement of two members relative to one another which overcomes the aforementioned drawbacks by preventing any disassembly and / or opening

  installations on which it is used, untimely unauthorized.

  The present invention relates to a device for locking the relative movement of two members relative to one another, in particular for removable wall supports, cabinet doors,

  gateways of candelabra or others.

  Although more particularly developed for such applications, it can also be used in all sectors of the economic activity in which it is desired to block access and / or

  prevent disassembly of an installation.

  As illustrated in FIGS. 1 to 3, the device I for locking the relative movement of two members 2, 3 with respect to each other, according to the invention comprises a housing 4 provided on one of the members 2, says fixed,

  said housing 4 being able to accommodate the other member 3, said mobile.

  The device I also comprises a retractable protrusion 5, able at least to open, through said fixed member 2, in said housing 4.

  to cooperate with said movable member 3.

  In order to prevent relative movement of said movable member when it is in the locking position, the device 1 comprises electromagnetic means 6 for blocking said projection 5 in said

housing 4.

  We give in the following some non-limiting examples

  application of the device 1 according to the invention.

  In Figures 1 to 3, said device 1 is housed in a tubular frame 7 and maintains a removable wall 8 such that, in particular, ice. For this, said fixed member 2 and said movable member form, for example, in the locking position, a groove 9 at their end provided opposite to said tubular frame 7, in which groove 9 said wall

  removable 8 is able to be introduced.

  According to the invention, said movable member 3 can be moved, for example, in the direction of the arrow marked 10, so as to be removed from said housing 4. The removable wall 8 can then be installed or deposited before returning said movable member 3 in said housing 4 and thus ensure

  the formation of the groove 9, after locking.

  Referring now to Figures 4 and 5, there is another example of application of the locking device 1 according to the invention to a cabinet or candelabrum 11 which it allows the blocking of the door or gate 12 For this, the fixed member 2 is secured to the walls 13 of said box 11 while the movable member 3 is secured to said door 12 and can be moved, when the device 1 is unlocked, in the direction of the arrow

spotted 14.

  Turning now to the locking device I as such, it can be seen that, according to the illustrated embodiments, said electromagnetic locking means 6 are constituted by at least one

  electromagnet 15, secured directly or indirectly to said fixed member 2.

  Said electromagnet 15 is able, in particular, to allow the unlocking when it is traversed by a current and the locking in the opposite case. It is

  consisting, for example, of a coil 16 and a core 17.

  Said blocking means 6 further include, in particular, a blade of magnetic material 18, movable, secured directly or indirectly to said fixed member 2. Said blade of magnetic material 18 is adapted, for example, to directly or indirectly block the projection 5 in said housing 4 in the locked position and / or under the effect of the magnetic field created by the electromagnet 15, to leave said projection 5 free,

in the opposite case.

  When the electromagnet 15 is traversed by a current, said blade of magnetic material 18 is thus, in particular, attracted to said

electromagnet 15.

  As more specifically shown in Figures 1 and 2, said locking means 6 further comprises, optionally, a first spring 19, secured directly or indirectly to said fixed member 2, cooperating with said blade of magnetic material 18 to ensure locking. Said spring 19 thus allows, for example, to push said magnetic material blade 18 of the electromagnet 15 when the latter is not

more fueled.

  According to the illustrated embodiment, said blocking means 6 further comprise a movable pressure plate 20, directly or indirectly attached to said fixed member 2. Said pressure plate 20 cooperates, for example, with said projection 5. From moreover, it is adapted to be immobilized by jamming against said blade of magnetic material 18,

  when the device 1 is in the locking position.

  Said blades of magnetic material 18 and pressure 20 are, for example, rotatable, respectively, around a first 21

  and a second 22 axes, subject to the fixed member 2.

  Said pressure plate 20 has, in particular, an end cooperating with said blade of magnetic material 18, provided with a

beak 23.

  The latter comprises, on the one hand, an edge 24, forming in particular a steep slope favoring the abutment against said blade in

magnetic material 18.

  On the other hand, it should be noted that, during an unlocking, said pressure plate 20 is pushed back by the retractable projection 5 under the action of the displacements of the movable member 3 in the housing 4, as it is shown in Figure 1. If, when said pressure plate 20 is in such a withdrawal position, the power supply of the electromagnet 15 is cut off, the blade of magnetic material 18, repelled by the first spring 19

  could then block the device 1 in the unlocked position.

  In order to overcome this possible disadvantage, said spout 23 thus has, for example, an edge 25, forming a gentle slope, to avoid such inadvertent blocking of the device 1 in the unlocked position in case of

  cut off the supply of the electromagnet 15 during said unlocking.

  According to the illustrated embodiment, the blade of magnetic material 18 has a shoulder 26, adapted to cooperate with the edge

  abrupt 24 of the pressure plate 20 to also promote the arc-

6 2749606

  boutement. Said shoulder 26 is provided on said blade of magnetic material 18, for example, vis-à-vis said soft edge 25 of the pressure plate 20 when the latter is in the retracted position. This avoids the possible risks of blockage mentioned above. That said, said blade of magnetic material 18 is optionally constituted by two separate elements 27, 28 secured to each other and moving together. The first element 27 is formed by

  example, of a magnetic material and allows cooperation with the electro-

  magnet 15 while the second element 28 is formed, for example, of a more robust material, able to encourage the bracing against the blade of

pressure 20.

  Said locking means 6 furthermore comprise, optionally, a second spring 29, secured directly or indirectly to said fixed member 2. Said second spring 29 cooperates with said pressure plate 20 so as to allow the return of said projection 5 in said housing 4 Thus, when said pressure plate 20 is in the withdrawal position mentioned above, said second spring 29 exerts a return force and pushes said pressure plate 20 towards said housing 4, in position

  locking and / or when the movable member 3 has been extracted.

  In this regard, said movable member 3 has, optionally, a recess 30 in which said projection 5 is adapted to be embedded in the locking position. As to said projection 5, it consists, in particular, of a

  ratchet, sliding in a hole 31 provided on said fixed member 2.

  Said pawl 5 is formed, for example, of a ball, adapted to be embedded, as mentioned above, in said recess 30, provided

substantially hemispherical.

  According to the illustrated embodiment, said locking means 6 are integrated in a housing 32, formed by said fixed member 2. Said housing 32 thus encloses, in particular, the electromagnet 15, the blades 18, 20 of magnetic material and as well as their hinge pins 21, 22 and / or the first and second springs 19, 29. The reduction in the bulk of the

  locking device I, according to the invention, is thus favored.

  Moreover, to promote its manufacture, said housing 32 is in particular provided with a removable cover, for example transparent. The walls of said housing 32 have, in particular, one or more orifices 33 allowing, for example, the fixing of said housing 32 on its support, such as the tubular reinforcement 7 and / or the fixing, in its internal cavity, of the various elements

locking means 6.

  However, said housing 4 has, for example, the shape of a groove within which said projection 5 is transversely opening. In order to promote locking, the transverse clearance between said fixed member 2 and said movable member 3 in said groove 4 is minimum. As a remark, it should be noted that emergency unlocking means may be optionally provided in the event of malfunction of the electromagnetic locking means 6. They consist, for example, of a metal rod, intended to be introduced by percussion to inside the housing 32 to unlock the bracing, an impression on the outer surface of said housing 32 can be provided,

  in particular to facilitate the guiding of said metal rod.

  Referring now more specifically to FIG. 4, there is an embodiment of means 34 for actuating said locking device 1 according to the invention, allowing, in particular

  the electric power supply of the electromagnet 15.

  Said actuating means 34 are constituted, for example, by a lock 35, forming a female electrical socket, and by a

  key 36, forming a male electrical outlet.

  In addition, said key 36 comprises, for example, an electric battery 37, capable of constituting the power supply source necessary for the actuation of the device 1. The fact of providing said battery 37 in J

8 2749606

  said key 36 thus makes it possible to place the energy source allowing the unlocking to be outside the installation on which said device 1

  according to the invention is fixed and increases security.

  In addition, said key 36 is provided, for example, with a rod 38 comprising two electrical plugs 39, 40, connected at one of their ends to the terminals of said battery 37, and having, at their opposite end, two terminals 41, 42, arranged so as to be in contact with two

  terminals 43, 44, of given spacing, provided inside said lock 35.

  In addition to the possibly special profile given to said rod 38, the spacing that it will be necessary to provide said terminals 41, 42 provided at the end of said rod 38 to actuate the device 1, thus enhances the reliability of the lock. It should also be noted that, according to the illustrated embodiment, the housing 32 of the device 1 according to the invention and its actuating means 34 are dissociated and provided at two different levels in the

  facilities that are equipped. For this, said lock 35 and said electro-

  magnet 15 are connected, in particular, by electrical cables 45. Such a solution also makes it possible to reinforce the reliability of the lock offered by the

device according to the invention.

  In the case of the application of the invention to the locking of removable walls, including bus shelters, their supports are provided, in particular, with two locking devices according to the invention, accompanied by their corresponding actuating means, their key being

possibly identical.

  Naturally, other implementations, within the reach of those skilled in the art, could have been envisaged without departing from the scope

of the present invention.
