 The invention relates to a door accessory or equipment bearing the general reference (1) such as a door stop (lob), a door handle (4) or any other accessory as shown in Figure 1, it comprises advantageously a display device (2) intended to allow its display in the dark or at night. Therefore, the user thus has the possibility of locating the accessory (1) of the door (5) during a nocturnal movement without having to turn on a sometimes dazzling light such as, for example, a bedside lamp.

According to the various preferred embodiments of the invention, the display device (2) comprises at least one luminescent locating element (3) disposed on the accessory (1) or constituted by at least one element constituting the accessory (1), that is to say a part of the accessory or the accessory itself. This luminescent marking element (3) is advantageously obtained using luminescent pigments such as phosphorescent pigments or fluorescent inorganic or organic pigments. However, it appears that the phosphorescent type pigments have a greater afterglow in the dark and therefore seem more suitable for use than fluorescent pigments to achieve the set objective, however the use of fluorescent pigments may also present other advantages, such as color, intensity or economic or practical advantages linked to the manufacturing
According to a first embodiment, the accessory (1) comprising the display device (2) consists of a door handle (4) constituted by two parallel plates (6a, 6b) linked by one or more transverse screws (7a , 7b) as well as at least one actuating member (8) such as a lever, called a "stand" as shown in FIG. 2, or a pivoting cylindrical handle (50) as illustrated in FIG. 9, for example . The luminescent locating element (3) is advantageously constituted by the actuating member (8), namely, the lever or handle of the door handle (4).

 According to this first embodiment, the stand (8) is advantageously tinted in the mass using phosphorescent pigments to constitute the luminescent locating element (3).

It is made in one piece and is fully luminescent.

This stand is advantageously made of plastic by injection, the phosphorescent pigments being incorporated into the plastic before the injection of the part itself.

 The actuating member or handle (8) of the door handle (4) can also, according to a variant of the first embodiment, be constituted by an assembly of several parts (8a, 8b, 8c), one of them (8a) being made of mass-colored plastic and constituting the luminescent element (3) as shown in FIG. 3a.

According to this variant, the actuating member (8) comprises a guide rod (8b) and a handle body in two parts (8a, juice), the rod (8b) being partly threaded for example, while the part end (8a) constituting the luminescent element has a threaded internal bore so as to constitute a tip (8a) of a door handle crutch (8) capable of being assembled at the free end of the guide rod (8b ) as shown in Figure 3b. According to this embodiment, the stand body (8c) can be molded onto the guide rod (8b) for example.

 According to this variant, the luminescent part (8a) constitutes the end piece of the stand (8) and can advantageously be fixed by means of connecting means in a removable manner as shown in FIG. 3c.

Thus, the user can have luminescent tips and conventional tips and can change them at will according to the occupant that he accommodates in the room, for example. Note that the number of parts making up the handle can be variable. Similarly, the connecting means between said parts can be different. Thus, the stand (8) can consist of four parts (8a, 8b, &, 8d) assembled by clipping or by threading and whose luminescent part is constituted by the central part (8d) which has for example a form of revolution curved, as shown in Figure 4.

 According to another variant of the first embodiment which constitutes the preferred embodiment of the invention and which is illustrated in FIGS. 5 and 6, the accessory (1) consists of a door handle (4) and in particular by its crutch (8), the luminescent locating element (3) is advantageously arranged on the stand (8) so as to be visible from the front along F1 and laterally along F2. According to this preferred embodiment, the stand (8) is made for example of plastic by injection, it comprises a stand body (8c) disposed on a guide rod (8b). This stand body (8c) is provided with a longitudinal groove (15) extending over the front face of the lever proper as well as over at least part of the elbow (20) of the stand. Said groove being intended to serve as a housing (15) for the luminescent element (3) and can thus be occupied by a luminescent element (8a) of complementary shape made for example of plastic material tinted in the mass using pigments luminescent.

 The shape of the luminescent element (8a) being complementary to that of its housing (15), the luminescent element is thus visible from the front on the front face of the lever as well as laterally on at least part of the elbow (20) of the stand (8). The accessory (1) can be obtained by any other manufacturing process such as by bi-material injection or by overmolding for example but also by making the component parts of the accessory separately and by assembling them by any means such as by gluing or clipping for example. It goes without saying that the number, shape and location of the housing or housings of the accessory (1) intended to receive luminescent elements (3a, 3b) of complementary shape could be different without thereby departing from the claimed protective field of the invention. Thus, as shown in Figures 7 and 8, the actuator (8) may include two luminescent elements (8a, 8b) for example.

 According to a second embodiment, the luminescent marking element (3) consists of a painted area of the door handle (4). The painted area can advantageously be arranged on the actuating member (8) of the handle (4). According to this second embodiment and as shown by the different variants illustrated in FIGS. 7 and 8, the locating element (3) can thus be constituted by one or more patterns (3a, 3b), decorative or not, painted on the stand. (8) or on one of its constituent parts (8a, 8b, &, 8d) using a paint comprising luminescent pigments.

 According to a variant not shown of this second embodiment, the luminescent element is more generally constituted by a coating disposed at the periphery of the external surface of the stand or of one of the parts composing it. Said coating may consist of plastic overmolded, for example, by a paint, as described above, or be obtained by means of a surface treatment or any other process intended to have a layer of material containing luminescent pigments on a body. any.

 Note that the locating element (3) comprising the coating can be arranged in a removable manner as illustrated in certain embodiments described above. The concept of coating can, moreover, be interpreted in a broader sense and include modes of execution where the coating is, for example, constituted by a fabric painted or dyed in a luminescent manner. said fabric could advantageously be elastic, so as to enclose the crutch, for example, and thus constitute a removable sheath for a door handle crutch, that is to say a door accessory in itself.

 According to several variant embodiments illustrated in FIGS. 1 and 10, the door accessory (1) can be made up either of elastic door stops (lob), of door edges, of the plates (6a, 6b) of the door handle (4), for example, or by any other door equipment (s) such as a door frame (it). Note that said accessory can advantageously be constituted by a lock frame (the) so as to allow the location of the keyhole (13) at night, and this, in particular on the exterior doors or on the entrance doors.

 According to a variant not shown, the door accessory can be constituted by an actuating member of a double-leaf door or of a door of the type used to form the emergency exits of a room, this member actuation is advantageously constituted by a cross bar that the user actuates to open the door by pushing it from top to bottom. According to this variant, the luminescent locating element can be formed by all or part of the transverse tube so that its user can locate and activate it easily during an emergency evacuation of the room.

 It is important to note that the door accessory intended to be provided with a locating element according to the invention can be made of any material, such as for example wood, metal, plastic or any other material. .

 By tailors, the invention also relates to a method of manufacturing a door accessory (1) of the type described above and at least part of which is dyed in the mass by luminescent and advantageously phosphorescent pigments. The process comprises a main step consisting in including in a plastic material ready for injection a quantity of luminescent pigments, in a proportion varying between 1% and 20% by weight and advantageously chosen equal to 8%.

 Note that if we want to increase the intensity of luminescence, we can increase the percentage of luminescent pigments. The duration of persistence depends on the different types of pigments used. Thus, during the main stage of the process, the choice of the pigment or of a mixture of several pigments as well as the quantity of pigments used makes it possible to obtain the desired intensity and remanence.

 Note that the luminescent type marking element can also consist of self-adhesive strips or, for example, have the form of a magnetic type token, intended to be placed on plates of metal type door handles, by example.

 Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
