FR2793039A1 - Rimless spectacles with grooves in lens edges to receive rings of different colors that can be changed to matched clothing - Google Patents

Abstract

The spectacles have a nose bridge (1) and side-pieces (2) attached to the edges of their lenses (3), and each lens has a groove (31) in its edge (30) that can receive a colored ring (4) of an elastic material. The colored rings have an elasticity of between 1.2 and 2; they can be of toroid or other cross-section, and are made from a non-allergenic material.

Description

The subject of the present invention is a spectacle device of the type of which

  the trigger guard and the arms are fixed directly on the lenses but not on the edge thereof, for which the color of part of the frame can be changed without having to replace said frame. Such a device of glasses makes it possible to match the color to that of an outfit without that requiring having to

change glasses.

  The frame of a pair of glasses generally comprises two straps in each of which is embedded a lens, connected by a trigger guard and on each of which is fixed a branch by

through a hinge.

  Matching the color of such a pair of glasses to that of a dress is only achievable by replacing the frame with another of the same model, which has drawbacks on the one hand cost since it requires several mounts, and on the other hand of implementation to carry out the removal and the installation

glasses.

  To overcome these drawbacks, glasses devices have been proposed on the frame of which can be

  alternately fixed rigid faces of different colors.

  Such a spectacle device does not require the removal and installation of the lenses, it does however have the disadvantage that the faces must necessarily be of specific shape adapted to a frame model, which increases the manufacturing cost and therefore the

selling price.

  Furthermore, the aesthetic result of such a spectacle device is not always convincing, in particular because it is

  visible that the removable rigid face is attached to the frame.

  The object of the present invention is to remedy this drawback by proposing a spectacle device in which the color of a part of the frame can be changed without having to replace said frame.

mount, and for a low cost.

  The spectacle device which is the subject of the present invention is of the type whose trigger guard and the arms are fixed directly to the

  glasses but not on the edge thereof, and it is essentially characterized in that said glasses each have in their peripheral edge a groove capable of reversibly accommodating a ring of elastic material chosen from a set of rings of different colors . The elastic rings can be removed at will and replaced by others of different colors. In addition to their aesthetic function, the rings also protect the edges

glasses for possible impacts.

  It should be noted that, from document WO 96/30799, a spectacle frame is known, the lenses of which each have a peripheral groove at the periphery into which a ring is introduced.

  plastic material which serves as protection and decorative element.

  However, this ring is originally fitted and cannot be

  removed to be replaced by another.

  According to an additional characteristic of the device according to the invention, the elastic rings are made of a material

  whose coefficient of elasticity is between 1.2 and 2.

  A coefficient of elasticity between 1.2 and 2, guarantees good retention of the ring on the edge of the glass, while allowing easy removal thereof. On the other hand, such a coefficient of elasticity allows the rings to marry different shapes and

lens sizes.

  It will be noted that preferably the elasticity coefficient of the

  material of which the rings are made is of the order of 1.5.

  According to another additional characteristic of the device

  according to the invention, the elastic rings are toroidal in shape.

  The toroidal shape is the most suitable form for fixing

  in the groove and easy installation.

  According to another additional characteristic of the device

  according to the invention, the rings are of different sections.

  We can change not only the color of the straps

  glasses, but also the thickness of these straps.

  According to another additional characteristic of the device according to the invention, the rings have sections of different sections. Thus, a ring can for example comprise two sections, a thick section intended to border the upper part of the glass, and a

  thin section intended to border the lower part of the glass.

  According to an additional characteristic of the device according to the invention, the elastic rings are made of an hypoallergenic material. The elastic rings are thus advantageously made of silicone. The advantages and characteristics of the device according to

  the invention will emerge more clearly from the description which

  follows and which relates to the attached drawing, which represents one

nonlimiting embodiment.

  In the accompanying drawing: - Figure 1 shows a front view of a device for

glasses according to the invention.

  - Figure 2 shows a partial sectional view

  transverse of a glass of the same device.

  With reference to FIG. 1, it can be seen that a spectacle device according to the invention is of the type comprising a trigger guard 1 and branches 2 fixed directly on the glasses 3 while releasing

  the peripheral edge 30 of these.

  If we also refer to Figure 2, we can see that the peripheral edge 30 of each of the glasses 3 has a groove

  peripheral 31 o is housed an elastic ring 4.

  The groove 31 is of square section, while the ring 4 is of toroidal shape, its round section being of a diameter slightly greater than the width of the groove 31 so as to ensure a

  good fixing of the ring 4 in the groove 31.

  The rings 4 can be removed and replaced easily and quickly by others of different color, or by rings 4

  of different sections to vary the thickness of the strapping.

  4. Advantageously, whatever the model of glasses, the rings 4 can all be of the same dimension, the elasticity of the

  material of which they are made allowing to adapt them easily.
