Abstract

An adjustable anti-theft case (1) is described, of the type comprising item removal preventing means (2) from inside of the case (1) and comprising at least one side along its height (3) and one side along its depth (4, 44) which have a length substantially corresponding to or lower than the minimum length of the corresponding sides dell′item (2) of minimum sizes, at least one (3, 4, 44) of the sides (3, 4, 44) being made able to be elongated, through at least one extension (6, 46), over the minimum length, the side able to be elongated (3, 4, 44) being designed to be blocked in its elongation condition through the engagement between first engaging teeth (7) present on the extension (6, 46) and locking and unlocking means (14, 24) made of ferromagnetic material connected to the side able to be elongated (3, 4, 44) and projecting from its surface oriented towards the surface of the extension (6, 46), the side able to be elongated (3, 4, 44) being further designed to be unlocked from its elongation condition through the disengagement between the first engaging teeth (7) and the locking and unlocking means (14, 24) by means of a magnetic attraction force, the extension (6, 46) being equipped with at least one row of first engaging teeth (7) arranged next to a side end (15, 16, 55, 56) of the extension (6, 46), the locking and unlocking means (14, 24) being arranged next to at least one side end (25, 26, 65, 66) of the side able to be elongated (3, 4, 44).

Dependent claims

An adjustable anti-theft case of a type having means for preventing a removal of an item from inside the case, the case having a height and a depth and comprising:

a side element along its height and a depth element along its depth, the side element having a length substantially corresponding to or lower than a minimum item height and the depth element having a length substantially corresponding to or lower than a minimum item depth;
at least one of either the side element or the depth element being configured to elongate over a minimum elongation length;
wherein the element configured to elongate has a base portion and an extending portion configured to slide with respect to the base portion to an elongated condition;
further comprising an engagement element having a first set of first engaging teeth attached to one of the portions and first locking and unlocking means comprising ferromagnetic material attached to the other portion, the first locking and unlocking means projecting towards the first set of first engaging teeth, wherein the first locking and unlocking means is configured to engage with a portion of the first set of first engaging teeth when the case is in the elongated condition to lock the case in the elongated condition;
wherein the first locking and unlocking means further comprises second engaging teeth connected to a transverse pin made of ferromagnetic material, and an elastic means, wherein the pin and the second engaging teeth are biased towards the first set of first engaging teeth by the elastic means such that the second engaging teeth are pushed into mutual engagement with a portion of the first set of first engaging teeth, and wherein the pin is configured to be retracted by magnetic attraction force;
and
wherein the first locking and unlocking means further comprises a second elastic means made of ferromagnetic material, spaced apart from the second engaging teeth and configured and biased to engage another portion of the first set of first engaging teeth, and wherein the second elastic means is configured to be retracted by magnetic attraction force;
wherein the case is further designed to be unlocked and retracted from the elongated condition through disengagement between the first set of first engaging teeth and the first locking and unlocking means and between the second engaging teeth and the first locking and unlocking means by means of a magnetic attraction force;
and
wherein the case is configured to allow visibility of the item contained in the case.

a side element along its height and a depth element along its depth, the side element having a length substantially corresponding to or lower than a minimum item height and the depth element having a length corresponding to or lower than a minimum item depth;
wherein the side element is configured to elongate over a minimum side elongation length;
wherein the side element has a side element base portion and a side element extending portion configured to slide with respect to the side element base portion to an elongated side condition;
further comprising a side engagement element having a side set of first engaging teeth attached to one of the side element portions and a side locking and unlocking means comprising ferromagnetic material attached to the other side element portion, the side locking and unlocking means projecting towards the side set of first engaging teeth, wherein the side locking and unlocking means is configured to engage with a portion of the side set of first engaging teeth when the case is in the elongated side condition to lock the case in the elongated side condition;
wherein the case is further designed to be unlocked and retracted from the side elongated condition through disengagement between the side set of first engaging teeth and the side locking and unlocking means by means of a magnetic attraction force;
and
wherein the depth element is configured to elongate over a minimum depth elongation length;
wherein the depth element has a depth element base portion and a depth element extending portion configured to slide with respect to the depth element base portion to an elongated depth condition;
further comprising a depth engagement element having a depth set of first engaging teeth attached to one of the depth element portions and a depth locking and unlocking means comprising ferromagnetic material attached to the other depth element portion, the depth locking and unlocking means projecting towards the depth set of first engaging teeth, wherein the depth locking and unlocking means is configured to engage with a portion of the depth set of first engaging teeth when the case is in the elongated depth condition to lock the case in the elongated depth condition;
wherein the case is further designed to be unlocked and retracted from the elongated depth condition through disengagement between the depth set of first engaging teeth and the depth locking and unlocking means by means of a magnetic attraction force.
