Definitions
- the present invention relates to an anti-theft casing intended in particular to protect articles against shoplifting.
- Such housings are well known in their general principles. They usually include a movable trigger preventing the withdrawal of the protected article in the locked position, the trigger being held in the locked position by a member capable of interacting with a magnetic unlocking tool.
- the trigger is positioned at rest to partially close the insertion slot of the article, or to prevent one opening of an access hatch or the housing cover, or to block a housing comprising two rotating parts.
- the locking member is formed by a metal blade.
- This blade can be blocked quite easily, which results in the need for multiple manipulations before unlocking the trigger.
- this blade must necessarily be positioned very close to the surface of the housing, to allow satisfactory interaction with the magnet of the release tool.
- the object of the present invention is to remedy the drawback of the devices of the prior art, by proposing a new form of housing based on an operation different from that of the device described in patent EP666954, and avoiding the risk of inadvertent opening by the simple exit of the rod from the hole under the effect of a shock.
- the invention relates to an anti-theft box comprising a movable trigger preventing the withdrawal of the protected article in the locked position, the trigger being held in the locked position by a member capable of interacting with a magnetic unlocking tool, characterized in that that said member is formed by a metal counterweight having a shoulder which comes to rest in the locked position against a shoulder provided on the fixed part, the two shoulders being substantially perpendicular to the direction in which the movable trigger moves to pass into the unlocked position.
- the anti-theft unit comprises a means for pushing the trigger when at rest in a position in which the two shoulders interact to immobilize the counterweight.
- the trigger is movable according to a first longitudinal unlocking movement, parallel to the contact plane of the shoulders, with a stroke corresponding substantially to the length of the contact zone of said shoulders, and a second transverse movement possible when the counterweight is in the unlocked position.
- the housing according to the invention comprises an elastic means pushing the trigger at rest in a longitudinal locking direction.
- it has at least one longitudinal protuberance capable of coming into a longitudinal cavity complementary to the trigger of a depth substantially equal to the contact length of the shoulders.
- the counterweight is constituted by a cylindrical metal part.
- the trigger is produced in a single piece of plastic material having a housing for the counterweight.
- An additional object of the invention is to allow unlocking with different types of tools previously known for specific applications.
- Cassette anti-theft boxes of the prior art are not suitable for unlocking using a tool specifically intended for unlocking textile anti-theft devices, which generally have a hole at the bottom of which is the magnet.
- the secondary aim of the invention is to remedy this drawback by proposing an unlockable housing with the same tool as that used for the articles. textiles, and with great robustness and operational safety.
- the trigger has a substantially cylindrical protuberance inside which is the housing for the counterweight, the counterweight coming under the effect of a magnet against the front wall of this housing.
- FIG. 1 shows a partial view of the housing and the trigger, in the closed position
- - Figure 2 shows a partial view of the housing and the trigger, in the open position
- - Figure 3 shows a partial view of an alternative embodiment of the housing and the trigger, in the closed position
- FIG. 4 to 7 show a sectional view of an alternative embodiment, in the open and closed position.
- the housing (1) is formed by a plastic frame opening by a slot (1) for the introduction of an article such as a compact disc or a cassette.
- a trigger (3) partially seals this slot in the locked position. It thus prevents the withdrawal of the article. It can be moved to a position shown in Figure 2, where it completely releases the slot (2).
- This trigger is formed by a hollow molded part, closed at the rear by a wall (4) having a lumen (5).
- the housing has behind the trigger a stop (6) extending transversely, extended by a longitudinal projecting element (7) constituting a means for guiding the movement of the rear part of the trigger.
- this projecting element (7) allows on the one hand a displacement of the trigger in a longitudinal direction, and on the other hand a tilting of the trigger by pivoting around the contact zone between the edge of the lumen (5) and the longitudinal element (7).
- the trigger (3) has at its front part a housing (8) into which comes, in the locked position, a longitudinal stop (9) preventing transverse movement of the trigger (3).
- This stop is placed in the extension of a protuberance (10) of the housing extending towards the inside of the trigger.
- the rear part of this protuberance (10) has a shoulder (11). This shoulder (11) extends towards the rear of the housing, over a length 1 of a few millimeters.
- the trigger has a transverse chamfer (30) allowing tilting between a locking position shown in FIG. 1 and the unlocking position shown in FIG. 2.
- the trigger (3) also has a cylindrical housing (12) inside which is placed the metal counterweight (13). This counterweight is pushed transversely, towards the housing, by a spring (14).
- the counterweight (13) is extended on the side of the housing by a rod (15) on which is fixed a head
- the counterweight comes into contact, in the locked position, with one shoulder (11) of the housing. It thus prevents the retraction of the counterweight (13), even when the latter is subjected to the action of a magnet.
- the counterweight can be produced in the form of a rod made of a ferromagnetic material, or of steel, having an annular rib or by the association of a cylindrical magnetic or ferromagnetic part and of a foot forming one blocking shoulder.
- the housing also has an elastic blade (17) which bears against the housing (12) of the counterweight (13), or against another transverse wall of the trigger (3), to exert a longitudinal pressure tending to maintain the shoulders (11) and (16) in abutment against one another.
- the counterweight can therefore move under the effect of a magnet approached the surface of the trigger only when, at the same time, pressure is exerted on the front face of the trigger to uncouple the shoulders (11) and ( 16).
- Both the trigger and the flyweight are locked in the closed position. It is not possible to tilt the trigger in order to transversely move the front part into a position where it releases the slot (2), because the stop (9) cooperates with the cavity (8). To separate the stop (9) and the cavity (8), the trigger should be advanced, which is not possible because the head (17) abuts against the protuberance (10) of the housing.
- This pressure is opposed to the pressure exerted by the spring (17) and causes the disengagement of the shoulders (11) and (16).
- the counterweight (13) is always pushed back towards the housing by the spring (14). However, if a magnetic unlocking tool is approached to the wall (19) at the level of the metal counterweight (13), the latter is attracted to a position where the head (17) is positioned above the ramp ( 21) forming the outer face of the protuberance (10).
- the trigger (3) can then advance, which frees the cavity (8) from the stop (9), and which allows then the tilting of the trigger (3) around the light (5) and the longitudinal guide (7).
- This guide has a protruding bead (22) to avoid unexpected uncoupling of the trigger.
- This bead has a thickness determined so as to allow the force fitting of the trigger (3) on the housing (1).
- Figure 3 shows a view of an alternative embodiment.
- This variant differs essentially in that the lateral face (19) of the trigger is not planar, but has a protuberance (12) of cylindrical shape, comprising a cavity (23) inside which protrudes the housing ( 12) of the counterweight (13).
- This protuberance (12) is determined so as to allow cooperation with a textile unlocking tool, where the magnet is placed at the bottom of a cylindrical recess of a shape complementary to that of the protuberance (12).
- the protuberance (12) is intended to allow indifferently and without modification the use of a first type of unlocking tool having a cylindrical well at the bottom of which is a magnet, and a second type of unlocking tool having a surface plane fitted with a magnet.
- Figures 4 to 7 show alternative embodiments of a housing allowing the use of two types of unlocker.
- the movable member (40) has teeth (41) which cooperate with lugs (42) provided on the housing to prevent the opening of the housing in the locked position.
- the movable member (40) is pushed back by a spring in the unlocked position. It can be locked in the locking position by magnetic modular locking means.
- the first means consists of a blade (43) which is flat at rest, as shown in FIG. 6.
- a stud (45) is housed in the light (44) of the blade.
- This stud (45) forms a projection on the movable member (40).
- the blade being fixed relative to the housing, the movable member (40) and immobilized when the stud (45) enters the lumen (44).
- a magnet is approached to the surface of the housing, at the location of the blade (43), the latter deforms as shown in FIG. 5, to take a convex shape.
- the stud (43) is then released, and the movable member (40) moves under the action of the spring (46) in the unlocked position.
- the arming of the housing is done by pushing the movable member (40) into the locked position using the button (48) extending the movable member (40).
- the housing can be easily adapted for use with a well release, usually used for textile articles.
- a housing (50) in the form of a dome or cylinder, inside which is a counterweight (51) pushed back towards the movable member (50) by a spring (52).
- This movable member (50) has an annular groove (54) delimiting a shoulder (55).
- the movable member (40) has a stop (56) having a shoulder (57) coming to cooperate, in the closed position, with one shoulder (55) of the cylindrical counterweight (51).
- the movable member (40) is pushed back into the locked position using the arming button (48).
- the ramp (58) forming the rear face of the stop (56) pushes the counterweight (51) back into its housing.
- the counterweight (51) is located in front of the stop (56), it is pushed back towards the movable member by the spring (53).
- the movable member advances under the action of the spring (46) until the stop (56) come into contact with the counterweight (51). The housing is then locked.
- the movable member is pushed back using the cocking button (48).
- the shoulders (57, 51) are then disengaged, and a magnet approached the surface of the well (50) attracts the counterweight in a position away from the movable member, allowing the passage of the stop (56).
- the pressure on the cocking button is then released, and the movable member is pushed back by the spring (46) in the unlocked position.
- the adaptation of the housing to one or the other type of unlocking is done by placing either the blade (43) or the counterweight (51).
