Description:
BACKGROUND OF THE INVENTION  
         [0001]    The present invention relates to a device for detecting objects under insufficient lighting conditions.  
           [0002]    As is known, it is frequently necessary to detect objects or other driving elements, under insufficient light conditions or in the dark.  
           [0003]    Eyeglasses, watches, keys and locks thereinto said keys must be engaged, could not be seen under insufficient light conditions, thereby causing discomfort or dangerous conditions.  
         SUMMARY OF THE INVENTION  
         [0004]    The aim of the present invention is to provide such a device for detecting objects under insufficient lighting conditions.  
           [0005]    Within the scope of the above mentioned aim, a main object of the present invention is to provide such a detecting device which is very simple and flexible in operation, and which can be applied to any types of objects for allowing said objects to be easily detected under insufficient lighting condition.  
           [0006]    Another object of the present invention is to provide such a detecting device which is very inexpensive and does not require maintenance works.  
           [0007]    Yet another object of the present invention is to provide such a detecting device which is very reliable and safe in operation.  
           [0008]    According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a device for detecting objects, under insufficient lighting conditions, characterized in that said device comprises a body having a phosphorescent pigmentation and clamping means for clamping said body to an object to be detected.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0031]    With reference to the number references of the above mentioned figures, the detecting or signalling device according to the present invention, which has been generally indicated by the reference number  1 , can have a ring-like shape  2 , the ring being made of rubber or any other suitable resilient material, as shown in FIG. 1, or it can have a disc-like shape  3 , also made of an elastomeric or plastic material, having an adhesive surface, as shown in FIG. 5.  
         [0032]    According to the present invention, the device  1  comprises a phosphorescent pigmentation, to easily detect objects or articles in poorly lightened environments.  
         [0033]    In its elastomeric ring configuration  2 , the device can be advantageously applied to several objects or articles, even if the latter are not provided for such an application, such as, for example, to an arm  4  of an eyeglass  5 , as shown in FIG. 2, or to a key  6 , as shown FIG. 4.  
         [0034]    In this connection, it should be apparent that the above application examples have been herein illustrated merely by a non limitative example, and they must not be deemed as exhaustive of a lot of possible practical applications, and this owing to the advantageous construction of the device according to the invention.  
         [0035]    In its adhesive disc configuration  3 , the device can be advantageously applied, for example, to the plate  7  of a wall switch  8 , or at the key plate or lock  9  of a door  11 , or to the handle  10  of said door.  
         [0036]    In its elastomeric material ring configuration, the device according to the present invention can be further applied in yet other applications, in addition to the above illustrated applications.  
         [0037]    By way of an example, the device can be applied on door handles or knobs or on any other driving element to be detected in a dark environment, on watch bracelets, on radio set, on shoes, on motorcycle or bicycle portions, on jogging shoes, on wrists or ankles, on fishing net floats, on shoe cords, on dog and cat collars and on fittings therefor.  
         [0038]    As shown, the subject device has a sufficiently elongated configuration, so as to be easily wrapped in envelopes and to be easily applied to a lot of different objects.  
         [0039]    The ring element, in its elongated configuration, can have either a circular, elliptic or a polygonal cross-section.  
         [0040]    To that end, the ring element according to the invention must have a comparatively high elasticity and flexibility, so as to allow it to be easily knotted or wound on different objects.  
         [0041]    Thus, owing to its comparatively high resilient properties, the ring element can be subjected to pulling forces, to be properly elongated and then tightly and firmly clamped on the objects to be detected, to which it can perfectly adhere.  
         [0042]    It has been found that the invention fully achieves the intended aim and objects.  
         [0043]    In fact, the invention provides a constructionally simple and flexible device which can be virtually applied to any type of desired objects, even if the latter have not been set for such an application, and moreover it can be shaped as a frame, to allow the objects to be easily detected under insufficient or inexistent lighting condition.  
         [0044]    In practicing the invention, the used materials, and their contingent size and shapes, can be any, depending on requirements and the status of the art.
