Description

The present invention relates to the field of means for closing and securing a door of a storage. It relates in particular to a device for improving the burglary resistance of a locker, a chest, a cabinet, or any similar storage means.

The present invention is particularly applicable to storage generally used in the locker rooms of sports centers such as gymnasiums or swimming pools, or those used for example in locker rooms. Such storage allows the user to leave his personal belongings during his sport or his working time. It usually has a swing door to open and close a box in which the user can drop his stuff. A lock allows the locking, in the closed position, of the hinged door vis-à-vis the box. The lock used may be of various types, for example key or code, mechanically or electronically actuated, and may optionally implement a payment device or setpoint for example piece or token. Nevertheless, the locks used in this type of storage are generally simple and inexpensive, and therefore mono-point, that is to say ensuring a lock between the door and the box at a single point. This point is usually located about halfway up the door. A lock generally comprises a movable bolt that can engage in a strike. In the context of storage such as a locker room, the bolt is often carried by the locker door while the strike is attached to the locker or made in one of its walls. The opposite configuration is nevertheless possible. Depending on the type of lock implemented, the bolt may be movable in translation or be tilted into the striker.

Such a closure and locking device, simple and inexpensive, nevertheless has the disadvantage of being resistant to burglary attempts. In particular, it is often possible to separate the wall of the box of the locker (or more generally of the storage structure) vis-à-vis the door, at the lock. This can be achieved by introducing an object between these elements and levering to play on the flexibility of the wall of the box and / or to conceal the door. By doing so, it is possible to release the bolt from the strike, and open the door. There are known devices for burglar-proof locks, in particular locks with two or three points whose actuation entails, concomitantly with the introduction of the bolt into the striker, the movement of one or more bayonets each offering an inking point. additional upper or lower part of the door. Nevertheless, these devices are more complex and expensive than a single-point lock. They also require a good geometric adjustment of the door on the box, which increases the cost of producing the rack. However, this type of storage that is intended for changing rooms must be produced at the lowest possible cost, and must retain its functionality over time, despite a generally intensive use that can alter the geometric adjustments. In addition, it is not known to 20 devices for securing aftermarket pre-existing storage, equipped with single-point locks. The invention developed aims to solve at least one of the aforementioned problems, by providing a simple and inexpensive device to improve the burglary resistance of storage type locker, chest, or locker room. More specifically, the invention relates to an anti-burglar device for storage comprising a box, a swing door along an axis of rotation that can adopt an open position allowing access to the interior of the box and a closed position in which it closes the box and a lock enabling the door to be locked in the closed position, comprising: a first piece intended to be fixed on an inner face of the door, close to an outer edge of the door opposite to its axis of rotation; A second piece intended to be fastened to a wall of the box facing said external edge of the door when the door is in the closed position, in which one of said first piece and the second piece comprises an extension 5 ' extending perpendicularly to said inner face when the door is in a closed position, and the other of said first piece and second piece having a suitable orifice receive the extension when the door is in the closed position, so that when applying a force tending to move the outer edge of the door of the wall of the box facing said outer edge, 10 a support of the extension that includes one of said first piece and second piece on an edge of the orifice that comprises the other of said first piece and second piece generates a reaction opposing said force. Such an anti-burglar device thus makes it possible to secure a storage compartment with respect to the most common break-in technique consisting of moving the wall of the box facing the outer edge of the door away from the outside edge of the door. This is achieved by the implementation of two simple parts, which can be mounted in retrofit on pre-existing lockers. A simple lock, typically single-point, can be used successfully in combination with the anti-theft device.

In such a device, the extension that comprises one of said first piece and second piece is advantageously shaped so that the other of said first piece and second piece is interwoven with said extension in case of separation between the outer edge. the door and a wall of the box facing said outer edge, preventing rotation of the door to its open position. The extension may for example have a hook shape. The extension that includes one of said first piece and second piece may be substantially cylindrical or prismatic right, and have a transverse groove, said groove being dimensioned to allow the engagement of the other of said first piece and second piece in said groove in case of separation between the outer edge of the door and the wall of the box facing said outer edge.

In a first embodiment of the invention, the first part comprises the extension and the second part comprises a first plane 5 intended to be fixed in abutment on a wall of the box, and a second plane perpendicular to the first plane, said second plane having the orifice adapted to receive the extension of the first piece. In this first embodiment, the first piece may comprise a surface intended to be placed on the inside of the door, the extension extending substantially perpendicular to said surface. In a second embodiment, the second part comprises the extension and a first plane intended to be fixed in abutment on a wall of the box, and a second plane perpendicular to the first plane, the extensions extending substantially perpendicular to said second plane . In this second embodiment, the first part may consist of a plate having the orifice. In certain variants of the invention, whatever the embodiment, the second piece may comprise a receiving surface of a lock bolt so as to make a lock and ensure the locking of the door in the closed position. The first piece and the second piece can be zamak. They can be obtained by injection molding. The invention also relates to a storage comprising a box, a swinging door along an axis of rotation that can adopt an open position in which access to the interior of the box is possible and a closed position in which it closes the box, and a lock, said storage comprising an anti-burglary device as previously described. The invention also relates to a locker room with such a storage or several such storage.

Finally, the invention relates to a method of securing a storage unit comprising a box, a hinged door according to an axis of rotation that can adopt an open position in which access to the interior of the box is possible and a position closed in which it closes the box, and a lock, said method comprising: - providing an anti-burglary device as previously described; - Fixing on an inner face of the door, near an outer edge of the door opposite to its axis of rotation, the first part of the device; the attachment to a wall of the box, located opposite said outer edge of the door when the door is in the closed position, of the second piece of the device, so that the extension that comprises one of said first piece and second piece is received in the orifice that comprises the other of said first piece and second piece when the door is in the closed position.

Other features and advantages of the invention will become apparent from the description hereinafter. In the accompanying drawings, given by way of nonlimiting examples: FIG. 1 shows, in a three-dimensional diagrammatic view, a first example of a device according to one embodiment of the invention; - Figure 2 shows the device of Figure 1 according to another schematic three-dimensional view; - Figure 3 shows in a partial and schematic three-dimensional view, a storage equipped with the device of Figures 1 and 2; - Figure 4 shows, in a schematic three-dimensional view, a storage, namely a locker room, equipped with the device of Figures 1 and 2; FIG. 5 shows, in a partial and diagrammatic three-dimensional section, a storage unit equipped with a device according to the embodiment of the invention of FIGS. 1 and 2. FIG. 6 illustrates, by a partial and schematic three-dimensional view of a storage device equipped with the device of Figures 2 and 2, a particular function of this device; - Figure 7 illustrates, in a partial and diagrammatic view in three dimensions, a storage equipped with a second example of a device according to one embodiment of the invention; FIG. 8 shows, in a partial and diagrammatic three-dimensional section, a storage equipped with a device according to the embodiment of FIG. 7. FIG. 1 and FIG. 2 show a first example of a device according to FIG. an embodiment of the invention. The device shown comprises a first piece 1 and a second piece 2. The first piece 1 is intended to be fixed on an inner face of a door of a storage whose closure is to be secured vis-à-vis the attempts of breaking in. For this purpose, the first part 1 may comprise a surface 11 intended to be placed on an inner door face. The surface 11 may comprise, for example, holes for fixing by screw of the first part. The second piece is intended to be fixed to a wall of a storage box to secure. To this end, the second piece 2 may comprise a first plane 21 intended to be fixed in abutment on a wall of the box. The first plane 21 may comprise, for example, holes for fastening the second part by screws. A screw fixing of the first and / or second part is possible in particular when the casing and / or the door consist mainly of wood, agglomerated wood, or compact laminate material (also called "HPL"), which is commonly the case in the lockers or cupboards equipping the locker room of sports center. For metal lockers or cabinets, a fastening by welding or riveting is generally preferable, especially for the first piece fixed on a door.

The first part 1 comprises, in this first embodiment, an extension 12. The extension 12 extends substantially perpendicularly to the surface 11, so as to extend towards the inside of the storage box equipped with the device, when the door is in a closed position. The second piece 2 is configured to be able to surround the extension 12, when the first piece 1 is brought close to the second piece 2, that is to say when the fitted storage door is brought into the closed position. Indeed, the anti-bursting device proposed in the invention is particularly intended to equip a storage for example of the type shown in particular in Figures 3 and 4, comprising a box 3, a door 4 swinging along an axis of rotation 41 and can adopt a open position in which access to the interior of the box 3 is possible and a closed position in which it closes the box 3. In this first example of embodiment shown here, the second piece 2 comprises a second plane 22, perpendicular to the first plane 21. Typically, the second plane is therefore parallel to the inner face 42 of the door 4 when the latter is in the closed position. The extension 12 of the first piece 1, which is perpendicular to the second plane 22 of the second piece 2, passes through the latter through a hole 23 for receiving the extension 12 of the first piece 1. Thus, the second piece 2 is crossed by the extension 12 of the first part 1 when the door is in the closed position.

During the installation of the burglar device, a suitable relative positioning of the first piece 1 and the second piece 2 is necessary. In particular, the first piece 1 is intended to be fixed near an outer edge 43 of the door 4 opposite its axis of rotation 41. The second piece 2 is intended to be fixed to a wall 31 of the box 3 located 25 facing said outer edge 43 of the door 4 when in the closed position. The first piece 1 and the second piece 2 must also be positioned at a precise height of the arrangement to ensure their cooperation, that is to say, the fact that the second piece 2 surrounds, at least partially, the extension 12 of the first piece 1 when the door 4 is in the closed position.

In the example shown here, the first part 1 and the second part 2 are positioned so that the extension 1 passes through an orifice 23 formed in the second part 2 when the secure storage door is in the closed position.

In the example shown here, the extension 12 passes through the orifice 23. According to other variants, the orifice could be a blind hole receiving the extension 12 or a through hole formed in a thick zone. such that the extension would not exceed said hole opening once received in the latter.

In the exemplary embodiment shown, a transverse groove 13 is provided in the extension 12, giving it a general hook shape. The groove in particular has a width such that it allows the engagement of the second piece 2 in said groove in the case of spacing between the outer edge 43 of the door and the wall 31 of the box 3 facing said outer edge 43. Thus, the second piece 2 is nested in the first piece 1, which prevents the rotation around the axis 41 of the door to its open position, even in the case where a large distance between the door 4 and the wall of the box 3 makes the latch bolt out of the lock. Figure 5 shows in a sectional, partial and schematic, in three dimensions, a storage equipped with a device according to the embodiment shown in the previous figures. In this view, the box 3, seen from above and from the inside, is cut in a horizontal plane at the anti-theft device. This figure details an advantageous shape of the first part and the second part, in particular at their interface. According to this particular interface, in case of separation of the outer edge 43 of the wall 31, a projecting edge 24 of the orifice 23 is brought into abutment on the extension 12 of the first part 1, thus opposing the spacing between the outer edge 43 and the wall 31.

If a large force tending to move the outer edge 43 of the wall 31 is applied, for example by using a lever, the second piece 2 does not tear off the wall 31 but the projecting edge 24 engages the groove 13 so that the second piece 2 is nested with the first piece 1, which prevents the opening of the door 4.

FIG. 6 illustrates a particular variant of the invention in which the second part 2 is shaped to form the strike of a lock 5 of the casing 3. The casing 3 is here seen from the inside, without an upper wall or a wall 3034 The lock 5 is fixed to the inner face 42 of the door 4. The lock 5 here shown comprises a bolt 51 movable in translation. When the door 4 is in the closed position, the bolt 51 can be brought to the rear of an area of the second plane 22 of the second part 2, which thus forms the strike of the lock 5.

The door 4 is thus locked in the closed position. Other conformation of the second part 2 may be considered to form a lock strike. Similarly, various types of locks can be used, including various bolt mechanisms. In the example shown here, the lock comprises a deposit mechanism, as commonly used in storage 10 equipping the locker rooms of sports centers. Figures 7 and 8 show a storage equipped with a second example of a device according to a second embodiment of the invention. In many aspects, this second embodiment is similar to the first embodiment.

Thus, a first part 1 is intended to be fixed on an inner face of a door 4 of a storage unit whose closure is to be secured. A second piece 2 is intended to be fixed to a wall 31 of a box 3 of the storage to secure. Compared with the first embodiment presented above, the position of an extension 12 and a corresponding orifice 23 is reversed in the second embodiment. In particular, the second piece 2 comprises, in this embodiment, an extension 12. The extension 12 extends substantially perpendicular to the surface of the door 4 when the latter is in the closed position, that is to say say substantially parallel to the wall 31 of the box 3. The first piece 1 is configured to be able to surround the extension 12, when the first piece 1 is brought close to the second piece 2, that is to say when the equipped storage door is brought into closed position. Typically, the extension 12 of the second piece 1, passes through the first piece 1 through a receiving orifice 23 of the extension 12. For this purpose, the first piece 1 may be in the form of a simple plate comprising orifice 23. Advantageously, the door 4 may comprise a hole 44, 3034124 10 formed in front of the orifice 23, and providing a clearance sufficient to receive the end of the extension 12. Just as in the first mode of realization, the extension 12 may advantageously include a groove 23, which can give it the shape of a hook. In this variant of the second embodiment, the first piece 1, and in particular an edge of the orifice that it comprises, can fit into the extension 12 in the event of an attempt to break the storage unit equipped with the device. . The device developed in the invention, and in particular the first part 1 and the second part 2, can be produced according to numerous techniques making it possible to obtain suitable geometries. Typically, the first and second parts may be made of zinc alloy, especially zamak. Alternatively, the first and second parts can be made of plastic or reinforced plastic. They can be obtained by molding, in particular by injection. The first and second parts can also be formed in sheet metal. Optionally, machining the functional surfaces of the parts (metal or plastic) may allow greater geometric accuracy. For better securing storage, especially for large storage, several devices according to the invention can be used on the same storage. For example, for a cabinet 1.8 m high, three devices per door can advantageously be used. In particular, devices according to the first and second embodiments shown can be used together on the same storage. When several devices are used, they are advantageously distributed for example equidistantly, over the entire height (or more generally the dimension along the door) of the storage.

The invention thus developed makes it possible to secure a storage unit such as a chest, a locker or a cabinet. It can be applied to many types of storage, especially using a swing door vis-à-vis a fixed structure. The device developed tends to prevent tampering with the storage according to a procedure in which the outer edge of the door (edge opposite the axis of rotation of the door) is spaced from the fixed structure of the storage to remove the bolt from the door. lock equipping the storage of his 5 strike. According to some embodiments, even in case of spacing caused by a very large force, the two parts that comprise the device interlock and prevent rotation of the door. The device makes it possible to avoid the use of complex and expensive locks, and has the advantage, in many variants, of being able to be installed as a retrofit, on pre-existing storage units to be secured.
