PROCESS FOR CREATING A SUPPORT WHICH CAN BE FIXED TO SMOOTH WALLS AND MANUFACTURED ARTICLE OBTAINED BY SAID PROCESS

Abstract: The object of the invention is a process to create a support which can be fixed to smooth walls (P) which foresees a manufactured article (2), obtained by thermoforming of a plastic sheet, formed of a three-dimensional rigid central part (20) which has the function of support for an object (1) and a flexible peripheral part (3), suitably covered with adhesive, which acts as a surface of contact, and therefore an anchorage, with the wall (P).

Description: Process for creating a support which can be fixed to smooth walls and manufactured article obtained by said process. This invention concerns a process for creating a support which can be fixed to a smooth surface, for example the surface of a sheet of glass in a shop window or a domestic wall covered with smooth ceramic tiles, for objects with various uses, for example shelves, 5. clothes hooks, containers, advertising objects, etc. This same invention also concerns the manufactured article which can carry out said process. In order to assure the adherence of an object to a smooth surface one generally has to use pressure adhesive (or self-adhesive). This 10. solution, which is suitable for sticking a flexible plastic label to the glass of a window, is not suitable for anchoring a rigid, flat supporting base to the smooth surface of a wall. At present in order to stick a rigid body - for example the base of a clothes hook - to a smooth surface one has to use a felt square 15. (or a pad made of foamed plastic), covered with adhesive, which is placed between the wall and the resting surface of said body. However the felt square covered with adhesive, apart from making the joint between the object and the wall cumbersome, has the inconvenience of providing an anchorage which is not always secure, 20. since it can break off from the wall due to the considerable elastoplastic deformations. Finally it is superfluous ro recall the difficulties of using suction CUDS. The aim of the invention is therefore to provide the possibility of supporting, in a practical and secure way, any object, fixing it to smooth surfaces. The above aim has been reached by providing a manufactured article 5. obtained by thermoforming of a plastic sheet, appropriately shaped so as to have a three-dimensional, rigid central part and a peripheral, flexible part, which can be covered with adhesive. The manufactured article has a rigid central part which acts as a support for the object to be fixed and a peripheral, flexible part, 10. which will be covered with glue which acts as a contacting surface, and therefore an anchorage, with the wall. Preferably the rigid central part of the manufactured article is shaped so as to receive the object to be supported. The rigidity of the central part can be obtained by molding the 15. central part so as it acquires a three-dimensional shape. Possibly the rigidity can be increased by the addition or inclusion of other rigid elements. The shape of this central part depends on its function, for instance a shelf supporting objects or a frame holding a mechanism. 20. The flexibility of the peripheral part of the manufactured article is obtained by adapting said part to the surface to which the object must be fixed, i.e. generally to a flat, or slightly- convex or concave surface. The flexibility of the peripheral part is increased by providing a suitably small thickness. The thickness of this parr must be small enough to provide flexibility, however not so small to invalid the rigidity of the central part and the mechanical resistance of the manufactured article. In conformity with the invention the peripheral part covered with 5. adhesive can either be made of more separate parts which are not connected to each other, for example tongues, which jut out from the rigid part, or else can be a single continuous peripheral frame. An adhesive means can be spread, or else a double-sided adhesive film, available on the market, can be applied to the peripheral part 10. of the manufactured article replacing the pressure adhesive. In conformity with the invention, the manufactured article is applied to -a smooth wall in the desired position so as to stick to said wall by means of the adhesive covering the peripheral part, while the central rigid part houses and supports the object. 15. Objects can thus be fixed to a smooth wall without having to use felt squares or the like. The connection with the wall is then as a whole more rigid, more stable and less cumbersome than that of the solution with the felt square. The simple construction of the manufactured article bears an economic advantage. 20. Thus small adhesive shelves, advertising objects, monitors, supporting mechanisms for the movement of moveable parts, self-adhesive containers of various shapes and sizes, and other objects useful for shops, cars or the house can be easily carried out. - A - The invention will now be clarified by means of non-restrictive embodiments, illustrated in the attached drawings, in which: fig. 1 shows a frontal view of a first example of a manufactured article capable of supporting an object fixing it to a 5 # smooth wall; fig. 2 shows a section along line 2-2 of figure 1; fig. 3 shows a frontal view of a second example; fig. 4 shows a section along line 4-4 of figure 3; fig. 5 shows a frontal view of a third example; 10_ fig- 6 shows a section along line 6-6 of figure 5; fig. 7 shows a frontal view of a fourth example; fig. 8 shows a section along line 8-8 of figure 7; fig. 9 shows a view from above with respect to figure 7. In figures 1 and 2 a self-adhesive shelf 10 is shown made by 15. thermoforming a rigid plastic sheet, for example a polyvinyl chloride sheet, having a thickness, for example of 0.5 mm. In this manufactured article which is made of one piece, the pressure adhesive is inserted between the article and the wall P along the flat anchoring surface made from the peripheral part or frame 5 20. shown in figure 1. The thickness of the frame 5, after the thermoforming, is of 0.2 mm. The small thickness of this frame 5 guarantees the necessary flexibility so that said frame 5 can stick perfectly to the wall P without risk of breaking off. The central part of the manufactured article has been thermoformed into a 25. three-dimensional shape having the functional characteristics of a shelf. It results rigid. In this central part a resting plane 6, capable of supporting an object, and supporting sides 7 are visible. In figures 3 and 4 a hook 1 is shown having a one piece rigid plastic basement obtained by injection molding. The hook 1 is fastened with screws 4 to the central part 20 of a manufactured article 2 in a single piece carried out by thermoforming of a rigid 5 # sheet of PVC having a thickness for example of 0.4 mm. A pressure adhesive is interposed between the thermoformed manufactured article and the wall P according to the surface of contact made by the frame 3. The peripheral part, or frame 3, on which the adhesive is applied has thickness appropriately less than that of the central part which 10. is next to the hook 1, for example a thickness of 0.3 mm. As can be seen from these figures the manufactured article 2, sticking by it's frame 3 to the wall P, fixes without danger of the hook 1 breaking off from said wall P. In figures 5 and 6 a self-adhesive shelf 30 is shown, the process of 15. manufacture of which being similar to that of the shelf of figures 1 and 2, but differs from this due to the fact that its anchoring surface is made of only two separate parts which have the appearance of two tongues 8 and 9 jutting out from the central body. As can be seen in figure 6, the central part 33 of the manufactured article 20. receives a stiffening element 31. This element 31 can be fixed to the shelf 30 during the production or else it can be inserted afterwards. The tongues 8 and 9 can also be provided so as to result inwardly turned. The pressure adhesive will be inserted between the tongues ' 25. and the wall. This advantageous solution allows that the parts covered with adhesive are invisible because they are placed on the back of the rigid part of the manufactured article. Finally in figures 7, 8 and 9 a manufactured article 40 is shown, the central part 41 of which receives the mechanism, indicated on the whole with 45, of a device acting for example as a parking timer. This timer is fixed to the rigid central part 41 by pivots 5. 46. The central part 41 of the manufactured article has an opening 44, through which the control handle 43 can be operated. The peripheral part 42 has a slightly convex shape, as can be .seen in figure 9, in order to perfectly stick to the windshield of a vehicle.
