Definitions

  • the present invention relates to an improved seal with anti-theft device for articles having slender portions.
  • Such seal is particularly suitable to be applied to the temples of eyeglasses.
  • eyeglasses are currently usually provided, at points of sale, with suitable seals on which a customizing decoration or, more simply, the trademark of the manufacturer is applied.
  • an anti-theft device that is capable of activating electronic alarm circuits, which are usually arranged proximate to the exits.
  • the seals usually comprise a box-like body from which a tab protrudes which is constituted by articulated consecutive elements and is shaped so that it can fold back, so as to produce, in combination with said body, a containment seat for the slender portion of the article to which the seal is to be applied.
  • An electronic signaling component of the per se known type is inserted in the box-like body.
  • the seal is provided with a slider, which engages irreversibly a guide that is rigidly coupled to the box-like body.
  • the slider has a mushroom-shaped head, which enters and slides within a complementarily shaped seat formed in the tab, so as to block said tab in the folded position.
  • the slender portion is retained in the seat formed by the folding of the tab by way of the irreversible locking of the slider.
  • the slider slides in a direction that is perpendicular to the slender portion and lies on the imaginary plane, formed by the box-like body, on which said slender portion rests.
  • the retention of the temple is in fact provided by the head of the slider and by the edge of the tab, and is therefore performed on a plane that is parallel to the contact plane.
  • the structure of the body of the seal allows a limited sliding range for the slider, to the point that it may reach the end of its stroke without being able to lock the slender portion conveniently.
  • the seals can in fact be applied to a temple without ensuring the locking of said temple in the containment seat, and while preventing extraction they can however rotate easily with respect to said temple, reaching an inclined position and thus making it difficult to arrange the eyeglasses in display stands.
  • the seals currently widely in use can be reused only partially, since in order to disengage them from the portions to which they have been applied it is necessary to break the mushroom-shaped head of the slider and it is then necessary to have a replacement part for the slider before being able to reuse said seals by applying them to a new slender portion.
  • a seal with anti-theft device which comprises a hollow body, suitable to contain an electronic signaling component, which forms a contact plane for a slender portion.
  • each guide has at least one sawtooth engagement surface for the irreversible sliding, along a direction that is perpendicular to the plane, of a slider that has wings with complementary sawtooth engagement surfaces.
  • the slender portion is retained between said plane and a parallel plane formed by said slider.
  • a first lining element is glued onto said hollow body in the region between said two guides.
  • a second lining element is instead glued onto the lower face of said slider and is interposed between said complementary sawtooth engagement surfaces.
  • annular lining element in which said slender portion is to be inserted has been arranged between said sawtooth engagement surfaces of the slider and has been rigidly coupled thereto by being monolithically provided with a tab, which is likewise annular and surrounds a portion thereof, but this has entailed a certain constructive complication of the assembly.
  • the aim of the present invention is to provide a seal with anti-theft device for articles having slender portions that solves the drawbacks noted above.
  • an object of the present invention is to provide a seal with anti-theft device that cannot be slid off the article to which it is applied and which has reduced dimensions.
  • Another object is to provide a seal with anti-theft device that can also be applied to slender portions that have a small cross-section without the possibility of unwanted rotations or movements.
  • Another object is to provide a seal with anti-theft device that can also be applied without problems even to considerably large and slender portions.
  • Another object of the present invention is to provide a seal that can be reused completely after the article to which it is applied has been sold.
  • Another object of the present invention is to provide a seal with anti-theft device that is composed of a reduced number of parts that can be mutually assembled easily.
  • Another object is to provide a seal with anti-theft device that can be applied simply and rapidly.
  • Another object is to provide a seal with anti-theft device whose cost is comparable with that of known types.
  • a seal with anti-theft device for articles having slender portions of the type that comprises a hollow body, which contains an electronic signaling component and forms a contact plane for a slender portion of an article to be protected, a pair of parallel and mutually opposite guides for a substantially bridge-shaped slider protruding from said body, said slider having a flat portion from the ends of which mutually parallel and facing wings protrude at right angles, said hollow body and said slider being coupled by means of irreversible engagement means, said slender portion being retained between said plane and a parallel plane formed by said slider, said seal being characterized in that said irreversible engagement means comprise a plate that protrudes from said body and is parallel and internal to each one of said guides, a portion having a sawtooth surface being formed on said plate at the outward face, said engagement means further comprising, on the inward face of each one of said wings, respective complementary sawtooth portions that are suitable to engage the corresponding portions having
  • a seal with anti-theft device for articles having slender portions is generally designated by the reference numeral 10 and is preferably made of plastics.
  • the seal 10 is applied to a temple 11 of a pair of eyeglasses, shown partially in the above cited figures for the sake of simplicity.
  • the seal 10 comprises a hollow body 12, which is substantially flattened and longitudinally elongated and on which there is, at a smaller face, a slot 13 through which an electronic signaling component 13a, of the per se known type, is inserted and subsequently sealed.
  • the body 12 forms, at a larger face 14, a contact plane for the temple 11.
  • Two mutually facing guides 15 protrude from the edges 14a of the face 14 at a central region.
  • Each guide 15 is monolithic with the body 12 and is substantially constituted by a wall that is perpendicular to the body 12.
  • a plate 17 protrudes from each edge 14a, between the blending portions 20, and is spaced from them; said plate is parallel and internal to a respective guide 15, and a portion 16 having a sawtooth surface is formed on said plate at the outward face.
  • holes 19a are provided in the contact plane in order to be filled with the material of the element 19 during injection-molding.
  • the seal 10 is completed by a slider 21, which is also preferably made of plastics, is substantially bridge-shaped and has a flat portion 22, from the ends of which mutually parallel and facing wings 23 protrude at right angles.
  • the inner regions 23a of said wings 23, adjacent to the flat portion 22, are separated from the remaining part of the wings by means of a through slot 23b, which is shaped like an inverter letter U and causes the inner part of each one of said wings to cantilever.
  • the regions 23a are therefore elastically flexible.
  • Respective complementary sawtooth portions 24 are formed on the inward face of each one of the wings 23 and are shaped so as to be adapted to engage irreversibly with the corresponding sawtooth portions 16 formed on each of the plates 17.
  • Each one of the sawtooth portions 24 is arranged between two flat regions 26, which are dimensionally equivalent to the spaces between the plate 17 and the blending portions 20.
  • the sawtooth portions 24 and the flat regions 26 are delimited externally by the slot 23b.
  • the slider 21 is suitable to slide, by means of the wings 23, along the guides 15 in a direction that is perpendicular to the contact plane of the temple 11.
  • said sliding is irreversible and is performed by the sawtooth portions 24, which mesh and continuously move past the sawtooth protrusions 16 of the plates 17.
  • each guide 15 there is, starting from the face 14, a recess 28 that is related to the corresponding wing 23 of the slider 21.
  • Respective through holes 30 having a rectangular cross-section are formed from the bottom of each recess 28 at its ends and are exactly aligned with the regions between which each plate 17 with a sawtooth portion 16 is arranged.
  • a plate-like contact element 31 made of soft material such as an elastomer is overmolded on the flat portion 22 between the wings 23 of the slider 21 and is rigidly coupled to said slider.
  • the temple 11 is therefore retained in the seat formed by the plane of the face 14 of the body 12 and by the parallel plane formed by the flat portion 22 of the slider 21 once it has coupled irreversibly to the guides 15.
  • the slider 21 is capable of locking effectively slender portions that have both very small and very wide cross-sections without the possibility of unwanted rotations or relative movements or locking difficulties.
  • the lateral edges of the wings 23 have, at their ends, teeth 32 that are suitable to be inserted in appropriately provided undercut slots 33 located inside the blending portions 20.
  • Insertion occurs by elastic deformation of the blending portions 20 and allows preassembly of the slider 21 on the body 12.
  • seal 10 can be reused by using an extractor tool for disengagement, which is shown schematically in Figure 6 and is designated by the reference numeral 34.
  • the extractor tool 34 is in fact provided with two pairs of tabs 35 with wedge-shaped tips, each of which has an abutment region 36 at the part that lies opposite the tips.
  • the tabs 35 can be inserted in the openings formed, in this case, by the holes 30 until the tips of the wings 23 abut against the abutment regions 36.
  • the tabs 35 act on the regions 23a of the wings 23 so as to flex them outward and simultaneously disengage them from the plates 17.
  • the sawtooth portions 24 of the wings 23 in fact disengage from the corresponding sawtooth portions 16 of the plates 17, thus allowing the uncoupling of the slider 21 and accordingly the opening of the seal 10.
  • the slender portion is retained between the slider 21 and the body 12 on a plane that is perpendicular to the contact plane of said temple.
  • Another advantage of the present invention is that it provides a seal with anti-theft device whose cost is fully comparable with the cost of known models.
  • the materials employed may be any according to requirements.
