Description

SPORTS SPECTACLES WITH AUXILIARY OPTICAL PARTS Technical Field
The present invention relates to sports spectacles with auxiliary optical parts.
Background Art
Noted problems which need to be addressed with the use of sight-aiding glasses or also of protective glasses with neutral lenses, such as those for skiers or for cyclists, include providing protection against solar radiation or against sudden brightness changes such as those which occur at the exit from a tunnel.
The problem constituted by sudden brightness changes is generally solved by applying additional darkening lenses which are suitable for permanently or temporarily replacing those being used.
The darkening lenses are currently applied with various methods, for example by fixing with removable elastic means, or by pivoting them on the front part of the glass frame, or by accommodating them inside the front part, etc.
However, all known application systems, both temporary and/or permanent, have a series of problems which include: the difficulty which arises in applying or replacing the lenses; the time requirements for application thereof; and the bulkiness of the spare lenses.
All these problems lead the user to suffer the negative effect of sudden or intense radiation rather than apply protective auxiliary lenses. Disclosure of the Invention The aim of the present invention is to provide spectacles with auxiliary optical parts which can be superimposed on the main optical part in an easy and rapid manner.
A consequent primary object is to provide spectacles wherein the auxiliary optical parts are constituted by darkening lenses to be superimposed on the main optical part in case of sudden brightness changes or of persistent intense radiation.
Another important object is to provide spectacles wherein the auxiliary optical parts are arranged so as not to produce bulk both during inactivity and during use.
A further object is to provide spectacles which have a dual optical and/or protective function as well as a darkening function.
Not least object is to provide spectacles with a particular design which lends itself to combinations of new and original color forms.
This aim, these objects and others which will become apparent hereinafter are achieved by sports spectacles with auxiliary optical parts, characterized in that it comprises a front transverse element at whose ends the temples are articulated, said element supporting a fixed main optical part and two auxiliary lenses which are slidingly fixed thereto.
Brief description of the drawings
Further characteristics and advantages of the invention will become apparent from the detailed description of two embodiments thereof, illustrated only by way of non- limitative example in the accompanying drawings, wherein. figure 1 is a partially exploded plan view of a first embodiment of spectacles according to the invention; figure 2 is a rear view of the spectacles of figure 1, taken in the direction indicated by the arrow II; figure 3 is a front view of the spectacles of figure 1, with the auxiliary optical parts in their idle position; figure 4 is a plan view of the spectacles of figure 1, with auxiliary optical parts superimposed on the main part; figure 5 is a plan view of the spectacles of figure 1, with the auxiliary optical parts in their idle position; figure 6 is a sectional view, taken along the plane VI- VI of figure 4; figure 7 is a partially exploded front perspective view of a second embodiment of the spectacles according to the present invention; figure 8 is a rear view of an auxiliary optical part of the spectacles of figure 7; figure 9 is an enlarged transverse sectional view of a detail of the spectacles of figure 7; figure 10 is a top view of the spectacles of figure 7, with the auxiliary optical parts in their active position; figure 11 is a front perspective view of the spectacles of figure 7, with the auxiliary optical parts in their active position; figure 12 is a front view of the spectacles of figure 7, with the auxiliary optical parts in their idle condition. Ways of carrying out the invention With reference to the above figures 1 to 6, in a first embodiment the spectacles comprise a transverse and substantially circular arc-like element 1, below which a mask or visor 2 is coupled with a tight fit or otherwise stably fixed. Said visor is preferably constituted, for sports spectacles, by neutral material which has such a shape as to ensure maximum protection against air, wind etc. , but which can be constituted by, or in any case support, optical lenses for therapeutic use, combining the requirements of sight with the protective function.
A spacer 3 is arranged on the central part of the arc¬ like element 1, and a nose pad 5 is connected to a lower wing 4 thereof. The nose pad 5 has the function of softly resting the spectacles on the nose, contributing in any case to the overall stiffening of the structure.
Tabs 6 and 7 for the hinges 8 and 9 of the temples 10 and 11 are arranged at the ends of the arc-like element 1. The auxiliary optical parts comprise auxiliary lenses, respectively designated by the numerals 20 and 30, each of which is rigidly associated with a box-shaped arc-like slider, 21 and 31, whose internal cross-section is slightly larger than the cross-section of the arc-like element 1 which is inserted therein from the corresponding ends 12 and
13 of such element 1.
The sliding of the sliders 21 and 31 on the arc-like element 1 also entails the translatory motion of the respective darkening lenses 20 and 30, which can thus be completely or partially superimposed on the left and right parts of the visor 2.
It is evident that, for a better stopping of the auxiliary lenses 20 and 30 in the required position, there must be minimal play between the cross-section of the arc- like element 1 and the internal cross-section of the sliders 21 and 31 .
This stopping can be facilitated by the interposition of an elastic means or by the use of one of the many already-known adjustment and locking systems. The spacer 3 also has the function of stroke limit for the sliders 21 and 31 toward the central part of the arc¬ like element 1.
It should be furthermore noted that the box-shaped structure of the sliders 21 and 31 is open downward, and this allows both superi position on the visor 2 and superimposition on the tabs 6 and 7 for the pivoting of the temples 10 and 11, as well as the complete removal of the auxiliary lenses 20 and 30 without obstacles of any sort for them. With reference now to the above figures 7 to 12, a second embodiment of the spectacles according to the present invention comprises a front transverse element 101 which is constituted by two arc-like portions, respectively 101a and
101b, which are mutually connected by means of a straight central portion 101c.
Temples 102 and 103 are hinged at the ends of the front transverse element 101, whereas the central bridge 104 of a main optical part 105, constituted by a frame 106 for two lenses, respectively 107 and 108, and corresponding nose pads 109 and 110, is fixed at the central portion 101c for example by welding.
The lenses 107 and 108 may be either neutral or corrective.
Respective sliders 111 and 113 are slidingly rigidly associated on the arc-like portions 101a and 101b of the element 101 and have a C-shaped cross-section; corresponding auxiliary darkening lenses 115 and 116 are fixed to said sliders for example by means of rivets 112 and 114.
Advantageously, the frame of the spectacles, in particular the front transverse element 101, is metallic, whereas the sliders 111 and 112 are made of a plastic material and the coupling between them and the sliding portions is such that movement occurs with a certain friction. The stroke limit positions for the sliding of the lenses 115 and 116 are defined by the central bridge 104 of the main optical part 105 and by folds 117 and 118 by means of which the ends of the. portions 101a and 101b are connected to the regions for the pivoting of the temples 101 and 102.
The fact that the sliders 111 and 112 are made of a plastic material allows their elastic deformability and thus the easy separation of the auxiliary lenses 115 and 116 from the front transverse element 101. From what has been described above, it is fully evident that the spectacles according to the present invention, in both embodiments, has achieved the intended aim and objects. The translatory motion of the auxiliary lenses in fact does not entail particular problems, and said auxiliary lenses, by virtue of the simple circular-arc or double- circular-arc shape of the transverse elements, entail no particular problems of bulk, especially in their idle position.
It is also evident that it is possible to obtain a rapid and simple translatory motion of the auxiliary lenses upon a sudden change in lighting conditions.
Finally, it is evident that the auxiliary lenses may also be removed from the spectacles without problems of any kind. The invention thus conceived is susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept.
All the details may furthermore be replaced with other technically equivalent elements. In practice, the materials employed, as well as the dimensions, may be any according to the requirements.
Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the scope of each element identified by way of example by such reference signs.
