Definitions

  • Object of this invention is a new end hinging resilient device, particularly an elastic hinge for spectacles, for arms placed at the end of their glasses front piece, accomplished so as not to require the screwing of the hinging pivot and to assure its concealment from sight, besides presenting a minimal bulk, particularly in its thickness on the plain part of the arm.
  • Main feature of this invention is to provide a hinging resilient device for the movement of the ends of the arms on the end part of the glasses front piece by means of a pair of fixed loops or eyes, for instance, engaging with the end of a nose piece and being provided with a proper outer shoulder, while at the other end of the opposite arm to be linked a pair of side walls is provided.
  • Such side walls are properly square and spaced to each other by a middle opening that allows the housing of a carriage which supports an elastic means and is capable to compress the elastic means against the bottom of the opening, the carriage being also provided with a head loop to be linked to the above-mentioned pair of fixed loops , while the same side walls are pulled by the elastic means against the shoulder of the pair of fixed loops , in order to cause the opening, divarication and closing trips , i.e. movements , of the arm at the end of the front piece of glasses , blocking the hinging pivot in the loops and concealing it from sight.
  • the resilient hinges on the glasses frame notoriously have the task of making the adhesion of the glasses on the face of the person better, in addition to the advantage of permitting the release of the arms in their usual opening and closing positions onto the front piece.
  • the elasticity of the mentioned glasses hinges is actually accomplished in different constructive ways and embodiments generally based on the compression of elastic means kept in a box linked to the end of the arm or placed in a bored end of the arm, said elastic means being linked to an arm hinging loop that can slide into the same seat of the elastic means, to overcome, thanks to the movement of the arm, the eccentricity of the loop of the end of the front piece .
  • This problem constitutes a great uncomfortable condition for the worker that has to apply and close the little screw or pivot, after having forced the alignment of the loops of the two parts of the hinge, dealing with extremely little components which are difficult to assemble because of the reaction of the elastic means that has to be shut up with an adequate preloading.
  • the present invention provides a solution to that and other problems .
  • the invention has the characteristic that it provides a pair of linked loops, for instance, engaged with the end of the glasses front piece, and is provided with a proper outer shoulder, while, at the end of the opposite arm to be linked, a pair of side walls is provided, the side walls being properly square, and spaced to each other by a middle opening that allows the housing of a carriage supporting an elastic means shut up in the carriage, the carriage being also provided with a head loop to be linked to the previous pair of fixed loops , while the side walls of the case that contains and blocks said carriage are pulled by the elastic means against the shoulder of the fixed loops .
  • an inventive application of the carriage containing the elastic means allows to link the advantages of a reduced bulk of the hinge to the possibility of eliminating the screwing of the pivot, in addition to the possibility of concealing the hinging pivot from sight.
  • Main object of the present innovation is, as a matter of fact, to accomplish a resilient hinge, particularly for the glasses arms, that assures their hinging onto their respective end of a front piece, without having to screw the pivot into a thread loop or into a nut placed at the bottom of the hinging end loop.
  • Another object of the present device is to conceal from sight the presence of the hinging pivot with consequent aesthetical gain, giving to the glasses a more plain aspect.
  • a further object of the innovation is to accomplish a kind of hinge that combines minimal bulk and the possibility of applying a pivot that can be screwed and cannot be seen from the outside .
  • Subject matter of the invention is a resilient hinge, particularly for spectacles , or the movement of an end of an arm on an end of a front piece of glasses by means of loops which are comprised by a body which is to be fixed to the front piece
  • a casing which is linked with one end of the arm and has a pair of projecting side walls which are spaced to each other by a central opening allowing the housing of a slider, said side walls projecting with respect to the central opening, and said slider being provided with elastic means and having at least one head loop which is to be inserted between and actually aligned with the loops of the body for being linked and hinged by means of a transversal pivot, characterized in that the projecting side walls are arranged such that the pivot is blocked and closed by the projecting side walls, when the body, the casing and the slider are assembled.
  • the loops are provided with a shoulder.
  • the projecting side walls are properly square .
  • the slider comprises an axial port for supporting the elastic means .
  • the port comprises a cylindrical side for engaging with a half-cylindrically shaped head which has a hole and is connectable to the elastic means .
  • the central opening has a cylindrical shape .
  • the central opening is adapted for housing the elastic means
  • the lateral grooves are adapted for housing the slider.
  • the depths of the grooves are greater than the depth of the central opening such that the elastic means is pressed against the bottom of the central opening for being preloaded.
  • the resilient hinge further comprises fixing means, for fixing the slider to the casing in the assembled state .
  • the fixing means comprise a screw which is insertable into a further opening of the casing.
  • the resilient hinge with blocked and hidden pivot is characterized by the fact that it comprises a resilient hinging device for the movement of the ends of the arms on the end of the front piece of glasses, by means of loops provided with shoulder and linked to a body fixed, for instance, to an end of the front piece, while at the end of the respective arm to be linked a case is applied provided with a pair of extended side walls properly squared spaced to each other by a middle opening that allows the housing of a slider or rod to support an elastic means to be loaded in said opening, said slider or strut frame being also provided with one or more head loops to be inserted and axially aligned with respect to the loops of the body of the front piece, to be linked and hinged by means of a transverse pivot that is then blocked and closed by the extended side walls of the case joint to the arm to be hinged, under previous blockage of the carriage or cage in the same case .
  • the resilient hinge comprises an end of front piece steadily linked to a fixed body, said body being provided with a pair of rings and projecting from a base that determines shoulders symmetrical and external to said rings .

  • Fig. 6 shows a perspective view of the hinge that can be accomplished with the components already illustrated in Figs . 1 to 5 , being already linked to each other and only need to be fixed with a closing screw;
  • Fig. 7 shows a perspective view of the same hinge of Fig. 6, which is illustrated completed also by the screw linking the fixed part and the mobile part which are aligned to each other along the same longitudinal axis for a usual opening condition of the arm on the glasses front piece;
  • Fig. 8 shows a perspective view of the same hinge of Fig. 7, the hinge being illustrated in a condition of largest divarication of the arm on the front piece
  • Fig. 9 shows a perspective view of the same hinge of Figs. 7 and 8, the hinge being illustrated in a condition of the arm on the glasses front piece when passing from the usual opening position to a closing, or reverse.

  • Fig. 13 shows two ends of front piece and arm united between themselves and hinged by means of the device constituted by the parts of Fig. 10.
  • an end of glasses front piece A is steadily linked to a fixed hinging element 1 , for instance by means of screwing or other means of steady linking, as well as an end of arm B is steadily linked to a mobile hinging element 2 , for instance by means of screwing or other means of steady linking.
  • Said hinging element 1 comprises a base 11 and a pair of loops, respectively eyes, 12 and 13 spaced by an opening 14, besides being provided with outer shoulders 15 and 16 accomplished on the base or fixing body 11.
  • the mobile hinging element 2 comprises a container or casing body 2 that is shaped as to house and block a slider or cage 3 , which houses an elastic means 4 , besides being hinged to its loop head 31 in the opening 14 between the loops 12 , 13 of the fixed element 1.
  • the container body 2 of the arm B is provided with a blind axial hole, having a cylindrical shape 21 and side grooves 22 and 23 which are able to house the cage 3 when laid flat, while the diameter of the hole 21 allows the passing and leading of the elastic means 4.
  • the same body 2 is further provided with a pair of side wings 24 and 25 projecting with respect to an inlet plane 26 of the hole 21 and being properly square in order to determine the usual opening or closing positions of the arms onto the front piece, according to a known technique .
  • the distance between the inner sides of the wings 24 and 25 is equal or lightly longer than the distance between the outer sides of the loops 12 and 13 of the fixed element 1.
  • a vertical groove 28 of the body 2 is so shaped that it can house the thickness of the loop head 31, when the slider 3 is completely inserted into the holes 21, 22 and 23.
  • the same body 2 is then completed by the presence of an opening 27 that can also reach to the lower surface of the hole 21 and that is able to house and block a closing screw 5.
  • the slider 3, as already mentioned, comprises a cage with the head loop 31 and with an axial port 32 , preferentially provided with a cylindrical side 33.

  • Said elastic means 4 is destined to be housed with a proper previous loading (preloading) in the port 32 of the cage or slider 3 in such a way that the cylindrical part of the head 42 of the guide 41 is contained in the cylindrical hollow 33 of the port 32. That means , the element 3 has two functions . The first function is to slide in the corresponding holes 21-23 of the body 2 while connecting the mobile hinging element 2 to the fixed element 1.

  • the end of front piece A and the end of arm B is provided with a fixed body 1 and a containment body 2, respectively, besides having at disposal the other parts above described and singled out in Fig. 1.
  • the elastic means 4 is housed by the axial port 32 of the cage 3 and linked with the guide 41 and the half-cylindrical head 42 as illustrated in Fig. 3.
  • the same pull rod 103 blocks the issue by means of a flattening or fastener 103' or with a cube provided with a thread or with another known blocking system.
  • the slider 142 is provided with a hole having a thread 143 for receiving the screw 105 for fastening the arm B such that it can be provided with shoulders 126 for the abutment against the pair of loops 112 and 113 of the front piece A which on its part is provided with shoulders 115 and 116 for receiving in abutment the square ends 124 and 125 of the arm B.
