Definitions

  • the present invention relates to restraints or grips for restraining a pair of spectacles from slipping off a wearer when in use.
  • a wearer such as a sportsman or manual worker, can perform movements which cause a conventional pair of spectacles to fall off and possibly break, such as when he moves his head to look down.
  • the side arms of spectacles may be bent so as more tightly to grip the wearer. This is not something that a wearer can easily do himself.
  • the arms are too tight against the head of the wearer, the pressure can cause discomfort to the wearer. If, however, the arms are too loose then the spectacles can easily fall off.
  • Another solution is to provide friction pads which are attached to the nose pieces of spectacles and engage either side of the nose of the wearer. These, however, are not easy to attach and are still not particularly effective in preventing the spectacles from falling off because the friction pads provide an insufficient gripping surface.
  • a grip for use on a side arm of a pair of spectacles so as to restrain the spectacles from slipping off the wearer when in use characterized by a sleeve member made of resilient material for fitting onto the free end of the side arm with an interference fit and having a gripping area on its outside defined by an array of resilient protuberances or pimples, said gripping area extending along the sleeve member and about a significant proportion of its periphery.
  • the significant proportion of the periphery of the gripping area may be, for example, at least 40 percent.
  • the grip is fitted to a side arm of a pair of spectacles so that the array of protuberances can bear against the head of the wearer. They may be manually rotated about the side arm, and/or the position of the grip may be adjusted along the arm, to suit the wearer.
  • the passage in the sleeve member may be star-shaped in cross-section.
  • the grip is desirably made of pliable rubber with the protuberances being pimples which are formed integrally with the remainder of the sleeve member.
  • the grip In use, the grip is fitted over the side arm of a pair of spectacles and is adjusted so as to sit on and behind the ear of the wearer, where it is quite unobtrusive. It can be made more cosmetically acceptable by being given a flesh like colour.
  • the protuberances or pimples may be dome shaped.
  • the sleeve member may be a cylindrical tubular member.
  • Fig. 1 is an isometric view of a pair of spectacles with attached grips according to one embodiment of the invention
  • Fig. 2 is an isometric view of one of the grips of Figure 1 ;
  • Fig. 3 is a side elevation of one of the grips shown attached to the free end of a side arm of a pair of spectacles;
  • Fig. 4 is a sectional view along the line 4-4 of Fig. 3;
  • Figs. 5 and 6 are similar to Figs. 2 and 4 and show another embodiment of the invention.
  • a pair of spectacles 10 having conventional side arms with grips 20 according to the invention fitted to the side arms.
  • Each side arm 30 has a free end formed by an inclined ear piece 40 to which the grip is fitted.
  • each grip 20 comprises a sleeve 50 formed from a short length of cylindrical tubing.
  • the sleeve has an outside surface 70 which has a recessed specific gripping area defined by an array of small resilient dome-shaped protuberances or pimples 80 similar to those which are provided on resilient thimbles of the type used to facilitate the sorting of paper sheets.
  • the tops of the pimples 80 are approximately coincident with the circumference of the sleeve.
  • the gripping area extends along the full length of the sleeve and about a predetermined arc of the circumference of the sleeve.
  • the passage 82 in the sleeve is star-shaped in cross-section, the points 84 of the star being formed between longitudinal ribs 86, which are triangular in cross-section, extending inwardly from the surface of the passage.
  • the sleeve 50 is moulded in one piece of a resilient material, preferably firm rubber.
  • the inside of the sleeve is dimensioned so that there is an interference fit between at least some of the ribs 86 and the inclined ear piece 40.
  • the ribs resist rotation of the grip 20 about the ear piece.
  • a person can manually rotate the sleeve about the ear piece, overcoming the resistance of the ribs, and/or adjust the position of the sleeve along the ear piece to suit the wearer.
  • the attached grips 20 are rotated into positions about the inclined ear pieces 40 so that the gripping areas faces towards and engage the side of the wearer's head. They frictionally engage opposite sides of the wearer's head to restrain the spectacles from falling off as a result of movement on head position.
  • each grip 20 is about 20mm to 25mm long with an outside diameter of about 8mm.
  • the size of these outside diameter helps make the spectacles feel comfortable to wear on the ears.
  • the points 84 of the star-shaped sleeve interior 82 are formed to approximately touch the circumference of a circle with a diameter of about 5mm.
  • the pimples 80 of the gripping area are about 1 mm to 2mm high and juxtaposed pimples are separated by about the same distance as the height. It is found that satisfactory restraint can be achieved with an array of pimples in a gripping area that covers at least 40 percent of the outside surface 70 of the sleeve.
  • the rubber material of the sleeve 50 helps make the spectacles feel comfortable to wear on the ears.
  • the pimples 80, as well as producing grip also provide a cushioning effect.
  • the grips 20 can be easily kept clean by removing them from the ear pieces 40 and washing or wiping them. They can also be washed or wiped whilst remaining attached to the spectacles 10. Dirt may collect around the pimples 80 and it is easier to clean the pimples by rotating the grips about the ear pieces so that the pimples face out from the spectacles.
  • the grips 20 on a pair of spectacles 10 are not visibly apparent as they are effectively hidden from view by the ears of the wearer.
  • the grips are made more cosmetically acceptable by being given a flesh like colour.
  • An advantage of the grips 20 described over known devices is that the grips can be variably and rotationally adjusted, if so required. Thus, the wearer can choose the position of the grips and the amount of grip that is required.
  • the grips not only provide an excellent restraint but also eliminate/alleviate pain, discomforture, and the need for difficult adjustment of the side arms of a pair of spectacles.
  • each grip 20a comprises a sleeve 50a formed from a short length of cylindrical tubing in which the gripping area is not recessed in the outside surface 70a.
  • the sleeve has a cylindrical inside surface 60 which is dimensioned so as to be an interference fit on the inclined ear piece 40.
  • a person can manually rotate the sleeve about the ear piece and/or adjust the position of the sleeve along the ear piece to suit the wearer.
  • the grip has an inside diameter of about 4mm.
  • the passage in the sleeve may of any suitable shape in cross-section to form an interference grip with an arm of the inclined ear piece.
  • the grips may be positioned on the main part of the side arms as opposed to the inclined ear pieces.
  • the pimples may be made of soft rubber for a tenacious grip.
  • the dome shaped protuberances or pimples 80 may be of other shapes, such as ribs separated from each other by troughs. Alternatively, these may be replaced by at least one continuous protuberance that winds or is of serpentine configuration throughout the gripping area.
  • the grips may be immovable, forming an integral part of the arms of the spectacles with the protuberances or pimples facing towards the wearer.

Abstract

L'invention concerne une paire d'attaches qu'on placent sur les branches d'une monture de lunettes de façon à retenir les lunettes et empêcher qu'elles ne glissent et tombent lorsqu'elles sont portées par l'usager. Chaque attache (20) comprend un manchon (50) confectionné dans un matériau souple, qui s'ajuste sur l'extrémité libre d'une branche de la monture au moyen d'un joint à ajustement serré, le passage (82) ménagé dans le manchon présentant une section transversale taillée en étoile. Le manchon présente, sur sa surface externe (70), une zone de prise délimitée par un réseau de protubérances ou grains souples (80). Cette zone de prise s'étend le long du manchon dont elle couvre au moins 40 pourcent du pourtour.
