IMPROVED SAFETY BOX FOR PUBLIC TELEPHONE BOOTH. DESCRIPTION The following invention, as expressed in the wording of the present specification, refers to an improved security box for public telephone boxes, in order to avoid fraudulent manipulations that can open the cashier and access the collection box . On the other hand, the door of the safety box that is presented lacks hinges and in its closing it is integrated in the front face, while the lock is protected, the case itself and an unlocking motor of the lock. SCOPE. In the present report, a safe box for public telephone boxes is described, which is of special application for its installation in public telephones to lodge in its interior the money collection box generated by the successive calls made. Also, the safe box for piggy bank can also be applicable for installation in other types of appliances or machines, such as vending machines and arcade machines. BACKGROUND OF THE INVENTION.
As is known, more often than desired, certain unscrupulous people try to appropriate the collection stored in the piggy banks housed in the corresponding box mounted under public telephones, mainly those installed in telephone booths. In this way, for the opening of the door of the safety box it is to act on its lock being able to use means such as a drill to make it "jump" and thus open the door without further problems. In order to avoid that it is possible to act on the lock, a system has been devised by means of which the cylinder rotates freely and does not affect the lock, being this type of locks of conventional type. Also, in those cases in which the safe box of the piggy bank has a hinged door and a bolt lock is to act on them to be defined by elements in which violent actions can be exerted when projecting from the general contour. On the other hand, we can consider the patent ES 2166344 which describes a security piggy bank for public telephones, as well as the patent documents WO 93/00496 and WO 99/53452. DESCRIPTION OF THE INVENTION. In the present specification a box of
improved security for public telephone boxes, being the type of security boxes that house the corresponding money collection box generated in the realization of the successive calls for the money introduced in the public telephone, until the collection, in a way that the safety box incorporates: • a displaceable plate, attached to the ceiling, provided with a plurality of openings and provided on its front side with a first flap provided with a series of holes and on one of its sides, relative to the assembly of the lock, of a second flap topped in a recessed inwards; • an engine fixed to the roof of the box and arranged in relation to an opening of the displaceable plate, whose motor drives a sliding plate locking plate and is controlled by an intelligent card fixed to itself; • a profile, of general section in omega "O" straight with respective orthogonal extensions on its external sides, fixed to one side of the box and in relation to which the partially removable lock is mounted externally fixed to the plate
displaceable The displaceable plate attached to the ceiling is mounted by means of screws and corresponding nuts, the screws being arranged in relation to corresponding holes ripped therefrom. On the other hand, in relation to the holes of the first front flap, in their open position, respective anchoring hooks of the closing door of the safety box remain. In this way, when moving the sliding plate in the closing operation, the door hooks snap into place. in, the first front flap, materializing its closure: Likewise, the displaceable plate attached to the ceiling, with respect to one side of the motor positioning opening, has an orthogonal flange, on whose orthogonal flange the stop plate actuated by the motor, in its closed position, preventing it from being displaced. In proximity to the motor fixed to the ceiling and transversely to the rotational movement of the locking plate, it has a pair of parallel lugs close to the orthogonal flange of the displaceable plate and between which it is aligned. The internal base of the lock body is fixed
sheet of height greater than the length of the core of the profile of general section in "O" straight and of smaller width to it. On the other hand, on the upper side of the roof, opposite the mounting side of the lock, the safety box incorporates an angle of reinforcement and protection, so that if it is to exert a vandalism, such as drilling, its purpose is avoided. To the recessing of the second flap of the displaceable plate is fixed, in relation to the assembly of the profile of general section in "O" straight, a sheet, defining a housing recess of the fixed plate to the internal base of the lock body. This execution means that if it is a question of acting fraudulently on the lock, the hypothetical release of the fixed plate to the internal base of the lock body, causes it to be housed in said box preventing a direct action for its opening. In the closed position, the fixed plate to the internal base of the lock body abuts on the general section profile in "O" and the blocking plate driven by the motor is disposed between the orthogonal flange of the sliding plate and the couple of close tabs. Thus, displacement of the sliding plate in any direction is prevented and the blocking plate does not
suffers any pressure. For opening the door the smart card controls that a numeric key has been entered, through the keypad of the telephone itself and having previously operated at least one key thereof before picking up the handset, ordering the motor to actuate it and the turn of the locking plate. Once the plate activated by the motor has been rotated, the unlocking of the displaceable plate is produced, allowing the removal of the lock body towards the outside by dragging the displaceable plate. In the partial removal of the lock body, displacement of the displaceable plate causes the orthogonal flange thereof to be positioned between the pair of close fixed lugs. To complement the description that will be made next, and in order to help a better understanding of the characteristics of the invention, this descriptive report is accompanied by a set of drawings, whose figures are illustrative and not limiting , the most characteristic details of the invention are represented.

DESCRIPTION OF A PREFERRED EMBODIMENT In view of the aforementioned figures and according to the adopted numbering, we can see how, starting from a conventional public telephone 1 with its corresponding handset 2 and keyboard 3 and equipped with a security box 4, with a door 5, which housing a collection box 6, the security box 4 incorporates a displaceable plate 7, attached to the ceiling, endowed with a plurality of
openings and provided on its front side with a first flap 8 and on one of its sides, relative to the assembly of the lock 9, of a second flap 10 terminated in a recess 11 towards the inside. Thus, the displaceable plate 7 is mounted by means of screws and corresponding nuts 12, the screws being arranged in relation to corresponding holes 13 thereof, allowing the guided displacement of the displaceable plate 7. On the other hand, the first front flap 8 is provided with a series of holes 14, so that, in its opening position, said holes 14 remain, relative to respective anchoring hooks 15 of the closing door 5 the safety box 4, so that when moving the plate 7 displaceable in the closing operation the hooks 15 of the door 5 are encased in the first front flap 8, as seen in figure 7 of the designs. The displaceable plate 7, with respect to one side of the motor positioning opening, has an orthogonal, stop and lock flange 20 in its closed position. Likewise, the safety box 4 incorporates a motor 16 fixed to the roof of the box 4 and arranged in relation to
an opening 17 of the displaceable plate 7, whose motor 16 drives a plate 18 for blocking the displaceable plate 7 and whose motor 16 is controlled by an intelligent card 19 fixed to itself. With regard to the assembly of the lock 9 partially removable towards the outside, the security box body 4 incorporates a profile 21 of general section in omega
"Or" straight with two orthogonal prolongations on its external sides and solidary to it for its soul. Likewise, in proximity to the motor 16 fixed to the ceiling and transversely to the rotational displacement of the locking plate 18, it has a pair of parallel lugs 22 close to the orthogonal flange 20 of the sliding plate 7 and between which it is aligned. To the internal base of the lock body 9 is fixed a sheet 23 of greater height than the length of the core of the profile 21 of general section in straight "O" and of smaller width thereto. Likewise, on the upper side of the roof, opposite to the mounting of the lock 9, the security box 4 incorporates an angle 24 of reinforcement and protection fixed by a pair of screws 25, so that if it is to act fraudulently, for example, by means of a drill, any action will be prevented, leaving the box 4
perfectly protected against vandalism. In addition, the recess 11 of the second flap 10 of the displaceable plate 7 is fixed, in relation to the profile 21 of the general section in straight "O", a sheet 26, defining a housing recess of the plate 23 fixed to the internal base of the lock body 9. Thus, if it is a question of acting on the lock body 9 with the intention of fraudulently opening the door 5 of the box 4, even if the sheet 23 were to be released and the door 23 could be rotated and removed to the outside. lock 9, the plate 7 would remain blocked by the action of the plate 18 driven by the motor 16, it being impossible to open the door.
In this way, if we look at the figure 7 of the designs we can see how, in the closing position of the door 5 of the box 4, the sheet 23 fixed to the internal base of the lock body 9 abuts on the profile 21 of general section in "O" and the blocking plate 18, driven by the motor 16, is arranged between the orthogonal flange 20 of the displaceable plate 7 and the pair of adjacent lugs 22. Thus, displacement of the sliding plate 7 is prevented and the door 5 is perfectly anchored by the hooks 15 embedded in the first flap 8 of the plate 7. For the operation of opening the door 5 of the
security box 4 the smart card 19 controls that a numerical key has been entered, ordering the motor 16 to actuate it and turn the locking plate 18, releasing the flange 20 and unblocking the sliding plate 7, allowing the removal of the lock body 9 towards the outside by dragging the displaceable plate 7, for which the lock has been turned 90 ° and with it the plate 23, which stops from touching the profile 21 (figure 8) and allowing its displacement. In figures 7 and 8 of the designs it is possible to observe the position adopted by the plate 7 movable in its closed and open position, being able to see how the plate .23 integral with the lock body 9, in its open position, passes between the wings of the profile 21 and drag to the plate 7. The door 5 on its inner side incorporates a flexible plate 27 by which, when the door has been released, drives it outwards, not requiring the door to incorporate any element of asido. Thus, in the partial removal of the lock body 9, displacement of the displaceable plate 7 causes the orthogonal flange 20 thereof to be positioned between the pair of adjacent fixed lugs 22 (FIG. 8).
