  • the clamp 21 is preferably mounted on glasses A in such a way that the first arm 22' faces the exterior and, in any case, in such a way that, when the temples of the glasses A are folded, the first arm 22' is outermost and therefore associable with the magnetic element 11.
  • Clamp 21 moreover comprises a jaw 23, associated in a mobile manner with an arm 22' of U-shaped body 22 within the U. Operatively, jaw 23 can be pressed in closure on the portion of glasses A whic is embraced by the U-shaped body 22 through pressing means 24 (which will be described in detail below) in order to lock the U-shaped body on the portion of glasses A.
  • the jaw 23 consists of a lamina from which three perpendicular fins 26, 27 and 28 extend. These three fins 26, 27 and 28 slide in as many guiding seats 81, 82 and 83 provided in the first arm 22' of U-shaped body 21. The fins and the seats are shaped in such a way as to keep jaw 23 parallel to first arm 22', guiding backwards and forwards the translation movements of the jaw.
  • the pressing means comprise at least one threaded element 24 (e.g. a sprig or headless screw) inserted in the first arm 22' through an appropriate threaded through-hole 25.
  • the threaded element 24 can be screwed against jaw 23 to press it stably in abutment against a portion of the frame of glasses A already abutting with the second arm 22" of the U-shaped body.
  • the pressing means may comprise at least one elastic element interposed between the jaw 23 and the first arm 22' . This elastic element is arranged in such a way as to automatically press the jaw towards the second arm of the U-shaped body .
  • the magnetic spectacles holder device 1 comprises a safety string 50 intended to be fixed at one end (51) to the supporting means 10 and at the other end (52) to the holding means 20.
  • the string 51 has the function of keeping glasses A attached to the holding means in the case of accidental detachment of holding means 20 from supporting means 10.
  • the string 50 may be of the elastic type, for example in polymeric material, and in particular made in spiral form in at least one part. In this way, the string is shorter when not under tension, thus reducing the possibility of entanglement.
  • string 50 is made in a material insensitive to a magnetic field in order to avoid its being attracted by magnetic element 11 of supporting means 10 .
  • the clamp 21 comprises attaching means
  • the attaching means 30 comprise a through-hole 31 made on one of the arms of the U-shaped body, and preferably on the first arm 22' inasmuch as it faces the exterior of glasses A.
  • the through-hole 31 is obtained on the free head of the arm 22', in such a position as to avoid involving the internal part of U-shaped body 22.
  • on fin 28 of the lamina that forms jaw 23 there is a notch 29.
  • the attaching means 30 may comprise a ring 32 projecting on the first arm 22' of the U-shaped body (see Figure 8) or on the jaw 23 (see Figure 3) .
  • the attaching means 30 for string 50 comprise a quick-release coupling device 40 for the second end 52 of string 50 with regard to clamp 21.
  • quick-release coupling device 40 comprises a first element 41 intended to be stably fixed to clamp 21, and a second element 42 intended to be stably connected to the second end 52 of string 50.
  • the two abovementioned elements 51 and 52 can be snap- fastened together.
  • the first element 41 defines a housing seat 43 in which the second element 42 is intended to be inserted through an aperture 44.
  • the second element 42 is provided with a deformable portion 45 which is capable to pass from a retracted state, in which it is free to enter and exit from said housing seat 43 through the aperture 44, to an extended state, in which said deformable portion 45 - if inserted in the housing seat 43 - is retained within the latter by a undercut 46 with regard to the aperture 44.
  • the deformable portion 45 is shaped with regard to the aperture 44 and housing seat 43 to permit reciprocally free rotation of the two elements 41 and 42 of the quick-release coupling device 40. In this way also the string 50 is free to rotate on its own axis from its second end 52, thus avoiding bothersome tangling.
  • the quick-release coupling device 40 is made of a material insensitive to a magnetic field in order to avoid its being attracted by the magnetic element 11 of supporting means 10 and thus obstructing association of the clamp 21 with the magnetic element 11.
  • the two elements 41 e 42 are made with metallic wire (insensitive to a magnetic field, such as stainless steel for example) suitably curved and worked .
  • the first element 41 (intended to be stably connected to the clamp 21) consists of a length of wire which is centrally curved to form a substantially circular coil 61, in correspondence with which it is superimposed on itself at an angle of about 180°.
  • One end piece of the wire is then curved to form appendage 62 projecting radially from coil 61.
  • the other end piece of the wire (separated from the first one by coil 61) is curved to form a kind of ogive 63 set on plane p substantially orthogonal on respect of position plane g of coil 61.
  • the ogive 63 is provided at the apex with a ring 64 which is complanar thereto.
  • the second end piece of the wire terminates in hook 65 which, as may be seen in Figure 11, is separably fixed to appendage 62.
  • the element 41 thus shaped is connected to the clamp 21, placing the ring 64 stably in correspondence to through- hole 31 (as illustrated in Figure 9) or in correspondence to eyelet 32, after having inserted the hook 65.
  • ogive 63 defines the housing seat 43, while the coil 61 defines the aperture 44 of the element 41.
  • the second element 42 (intended to be stably connected to the second end 52 of string 50) defines a figure of axial symmetry as seen in Figure 11.
  • the second element 42 is defined by a length of wire centrally curved to form an ogive 74 corresponding substantially to the ogive 63 of the first element 41.
  • the wire is bent inwards at right angles, forming two indented portions 77 and 78.
  • the two end pieces of the length of wire are therefore shaped to form two arcs 71 and 72 that terminate each in a ring 73.
  • the wire is further shaped in such a way as to define two grip portions 75 and 76.
  • the ogive 74 defines the deformable portion 45 of the second element 42, while the two indented portions 77 and 78 define the undercut 46 of the second element 42.
  • the second end piece 52 of string 50 is inserted into the two rings 73 in such a way as to lock together the two arcs 71 and 72, favouring their elastic behaviour.
  • the ogive body 74 is elastically deformed thus reducing its size, passing from the extended to the compressed state to permit its insertion into the coil 61.
  • the insertion operation can be facilitated if as well as deforming the body of ogive 74 of second element 42 the coil 61 of first element 41 is also deformed.
  • any force of traction tending to separate the two elements 41 and 42 induces coil 61 to deform, reducing its radius, and therefore to retain more firmly the ogive body 74 of the second element 42.
  • the magnetic spectacles holder device 1 brings a series of advantages, already referred to in part.
  • a first advantage is that clamp 21 can be applied to any glasses frame, easily, practically and above all stably, without the need to disassemble any part of the frame itself.
  • a second advantage is that the safety string can be stably and securely connected to the glasses in correspondence to the clamp 21.
  • a third advantage is given by the possibility of rapid hook-up and unhooking of the string to/from the clamp .
