Definitions

  • the present invention concerns a screw device for clamping components of spectacles, having the characteristics mentioned in the preamble of main claim 1.
  • the invention also relates to a method of manufacturing the screw device.
  • the invention applies particularly to the specific technical field of spectacle manufacture, wherein screw devices of the aforesaid type, including a threaded shank which may or may not be provided with an operating head, are used for clamping a wide variety of components.
  • screw devices of the aforesaid type including a threaded shank which may or may not be provided with an operating head
  • Cited solely by way of example are the screw clamping of frame members, such as the lugs or the central nasal support bridges, to the corresponding "rimless” type of spectacle lenses, or the clamping of the threaded pins constituting the hinge pins in conventional spectacle frames, or also the clamping of "tube” appendages provided in the parts of lens-holding rims intended to be clamped to one another in order to hold the lens on the frame.
  • the screw connection should have characteristics such as to guarantee efficient locking and should prove to be reliable in maintaining the clamping action in order to oppose any unscrewing which might compromise the functioning of the spectacles. Description of the invention
  • the principal aim of the invention is that of providing a screw device for clamping components of spectacles which is capable of offering an improved and more reliable clamping action and which at the same time is of simple construction to produce, a further aim therefore being also that of providing a manufacturing method which fulfils that requirement.
  • Figures 1 and 2 are views respectively in front elevation and in plan from above of a first example of a screw device produced according to the invention
  • - Figure 2A is a view in partial section of a clamping system between a lens and a spectacle frame member in which the screw device of the preceding figures is used,
  • Figures 3 and 4 are views respectively in front elevation and in plan from above of a second example of a screw device produced according to the invention
  • Figures 5 and 6 are views respectively in front elevation and in plan from above of a third example of a screw device produced according to the invention
  • Figures 7 and 8 are views respectively in front elevation and in plan from above of a fourth example of a screw device produced according to the invention
  • Figures 9 and 10 are views respectively in front elevation and in plan from above of a fifth example of a screw device produced according to the invention.
  • Figures 11 and 12 are views respectively in front elevation and in plan from above of a sixth example of a screw device produced according to the invention
  • Figures 13 and 14 are views respectively in front elevation and in plan from above of a seventh example of a screw device produced according to the invention
  • Figures 15, 16 and 17 are views respectively in front and side elevation and in plan from above of an eighth example of a screw device produced according to the invention.
  • Figures 18, 19 and 20 are views respectively in front and side elevation and in plan from above of a ninth example of a screw device produced according to the invention.
  • Figures 21, 22 and 23 are views respectively in front and side elevation and in plan from above of a tenth example of a screw device produced according to the invention
  • Figures 24 and 25 are views respectively in front elevation and in plan from above of a further exemplary embodiment of the invention
  • Figures 26 and 27 are views respectively in front elevation and in plan from above of a further alternative embodiment of the invention illustrated in Figures 24 and 25.
  • Preferred ways of implementing the invention With initial reference to Figures 1 and 2, the reference 1 indicates as a whole a first example of a screw device for clamping components of spectacles, produced according to the invention.
  • the device also referred to hereinafter simply by the term “screw” is designed to be used in the most varied systems for clamping between spectacle components.
  • a first example of application is the screw locking of frame members (for example the lugs or central nasal support connecting bridges) to lenses or for the clamping of arms of spectacles to the corresponding articulation lugs in which the screw or the threaded pin may also function as a hinge pin.
  • Another example of application is that of clamping of the "tube" appendages provided on the lens-holding rims for clamping same in order to hold the lens on the frame.
  • Yet another example is that of the coupling of the screws with threaded bushes for fixing metal components onto parts made of plastics. It is to be understood that the screw according to the invention may obviously find application in all those screw fixing systems provided in frames for spectacles, in which the clamping of any desired component of the spectacles to another part or component of the frame is required.
  • the cut interruption 9 is preferably obtained by means of longitudinal cutting of the entire screw 1.

Abstract

L'invention concerne un dispositif de vissage destiné à des composants de blocage de lunettes, comprenant une tige (7) s'étendant dans un sens axial (X) et munie au moins partiellement sur l'extérieur d'un filetage (7b), au moins une partie axiale de la tige filetée (7) présentant une interruption longitudinale (9) s'étendant parallèlement au sens axial (X), interruption (9) définissant, de part et d'autre de celle-ci, au moins une première et une seconde partie (11, 12) de la tige filetée (7), le diamètre de filet de la tige (7) étant sélectionné pour être supérieur au diamètre de filet correspondant d'un écrou avec lequel la vis est destinée à venir en prise par vissage. La déformation élastique induite dans l'opération de vissage par la différence de diamètre de filet entre la vis et l'écrou et tendant à solliciter les parties (11, 12) de la tige filetée par un renvoi élastique de manière à ce qu'elles viennent contre l'écrou correspondant, augmente ainsi l'action de blocage entre les filets de la vis et de l'écrou en prise mutuelle.
