An accessory for attachment of promotional characters to pens, key holders and the like
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention refers to an accessory to be used for publicity and promotion, obtained from linking three dimensional symbols, in particular letters or numbers, with a cylindrical or generally prismatic body. 
     Discussion of the Background 
     For promotional or publicity activities the need is noted to affix in a clear way letters or various symbols on articles like pens, key holders, or similar objects. 
     Such letters or symbols are normally realized by way of typographic press, or by incision, or in relief on the surfaces of the abovesaid articles. 
     The above cited systems, though economical and easy to produce, do not always achieve their aim of displaying in a satisfactory way the letters or symbols fixed to the articles. 
     SUMMARY OF THE INVENTION 
     The present invention is an accessory to be used in promotional or publicity fields, which advantageously displays symbols or trademarks placed on the same, and which may be employed as a writing instrument, key holder, or similar object. 
     One aim of the present invention is to create an accessory which can be used for publicity or promotional ends, characterised by the fact that it is formed by linking various three dimensional object, in particular letters or numbers obtained by casting, with a cylindrical or generally prismatic body, on which they are forceably inserted. 
     A further aim of the present invention is in terms of producing in a simple and economic way an accessory with a publicity of promotional aim; whose cylindrical or prismatic part constitutes by itself, for example a writing instrument or a key holder or alternatively can be adapted to link on an end with a writing instrument or with the end part of a key holder or other object which can be used for publicity or promotional ends. 
     Further characteristics and advantages from the invention here described will be evident from the detailed description as follows, supplied with descriptive titles and therefore not limiting; making reference to the single attached table of drawings where: 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     FIG. 1 is the prospective, blow-up and entire view of the accessory realized with regard to the present invention; 
     FIG. 2 is a partial prospective view enlarged and blow-up from FIG. 1. 
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The accessory which may be used for publicity or promotional ends as is illustrated in FIG. 1, is formed by a body as in cylinder 1, which can also be made in a generally prismatic way, bearing a series of symbols, shown by FIG. 2 in the example given, made of plastic material, obtained by casting. 
     The abovementioned letters are inserted perpendiculary on the elongated body with respect to the axis of the same and are arranged with a small amount of space between them. 
     As illustrated in FIG. 2, the above mentioned letters indicated by 2 are inserted and blocked on the above mentioned elongated body 1 by way of complementary coupling means, present in both the letters and in the elongated body. 
     More specifically the above mentioned three dimensional letters present laterally an aperture 3, in diameter slightly greater with respect to the elongated body, and on the base a coupling means formed by a tooth 4, laterally incised and slightly projecting from the base of the letter. 
     In its turn, the elongated body, this too in plastic material, externally presents and opposite above mentioned letter tooth, a longitudinal channel with toothed borders constituting the complementary means of coupling. 
     Finally, in the illustrated example, the elongated body has a tapered extremity 6, to allow insertion of a manual writing instrument or key holder. 
     In accordance with another embodiment, the elongated body can be made so as to form itself a writing instrument or whatever other object with a publicity or promotional aim. 
     From what has been explained and illustrated above, it will be clear that the accessory above permits one to make a promotional or publicity object, when the writings present in the same are shown in the best way: being formed from symbols or three dimensional letters, forceably put together with a cylindrical or generally prismatic body using a complementary means of coupling: where there is blocking of the said letters or symbols, guaranteed by the toothed profile of the coupling mechanism, and where the abovesaid letters or symbols are slightly separated thanks to the means of coupling, which act so as to correctly distance the letters one from the other. 
     Further it is also clear that the link between the letter and the elongated body can be effected by way of whatever complementary connection and can permit the formation of whatever graphic symbolism on the body in addition to cylindrical, of whatever generally prismatic shape. 
     Considering the procedure principally describing the invention under discussion its practical production may vary widely, without, at the same time, going beyond the limits of the present invention, as protected by the following claims.
