Definitions

• Spotlights are usually embedded directly into false ceilings or walls made of plaster-paper which can easily be drilled according to the diameter required to accomplish a proper installation.
• each lights set is fixed by joining the plaster-paper slab between the spotlight outer frame and the two spring-arms stretching and opening out on the back.
• the purpose of this idea is to overcome all the above-mentioned troubles and offer the spotlights installer a built-in box which is universal, since it can be easily adjusted to the overall dimensions of each spotlight, and suitable also for temporary installation during the fixing with expanded polyurethane or cement mortar by means of a specific tool described and included in this industrial patent.
• this special box is designed to allow a proper loss of heat. Moreover, even if it is intended mainly for solving any kind of practical problem concerning the spotlight installation into brick or cement walls/ceilings, this special box is can also be employed as a safe and insulated housing for the spotlight, the transformer and respective electrical connections.
• FIG. 1 - 2 - 3 show the side views of the box main body
• FIG. 4 shows the box main body from above
• FIG. 5 - 6 show the box cap from above and from below respectively;
• FIG. 7 - 8 show the side views of the box cap
• FIG. 9 - 10 show the possible variations in the box volume according to cap positioning or reduction through cutting
• FIG. 11 - 12 show a section of the 3 -arm device of the special tool for the built-in box installation and the device as seen from above;
• - Fig. 13 shows a section of the rod that slides inside the 3 -arm device
• - Fig. 14 shows both the rod and the 3-arm device as a whole, thus forming the special tool for the built-in box installation;
• - Fig. 15 shows a vertical section of a built-in box installation through the special support
• FIG. 16 shows a vertical section of a spotlight installation once finished.
• this new built-in box is composed of a main body and a cap with different position slots. Every part is obtained through moulding and is made of plastic material (possibly in light colours) in order to obtain better light reflection and less heat absorption.
• the main body and/or the cap of this built-in box have some pre-cut parts ready to be detached in case of need to let electric wire sheaths pass by and loss of heat take place by using more sheaths or pipes which go through the box fixing material and reach the brick hollows. If necessary, they can also reach outside the wall.
• the main body which is cone-shaped, is larger at the top, so that it can be stacked up during stockpiling and transport, and smaller at the bottom. Both ends are open.
• the upper end which is larger in diameter and reaches the inner part of the wall, has to be capped whereas the bottom end, which is used for the spotlight installation, sticks out as a reference point for plaster finishing.
• a special device has been designed (see Fig. 11 - 12 - 13 and 14) which allows perfect positioning and sticking out of the box as well as its proper fitting during the fixing procedures (be it with cement mortar, expanded resins, etc.).
• the main body contains an inner series of step circles which form a winding spiral according to the shape of the box. Such rings correspond to as many outer indents to be chosen in accordance with the type of spotlight and, at the same time, allow a better hold of the inner spring-arms directly onto the ring levels.
• the main body is nearly cone-shaped at the bottom and consists of a series of rings with increasing diameters which fit to any type of spotlight.
• the upper part has a similar shape with two side "P" sections which, facing the opposite direction, permit the spotlight spring-arms to open wide properly.
• the "A" ring connection is pre-cut since it is limited to short thickening sections. Moreover the cutting procedures can be easily carried out by means of a jigsaw and are made even easier because of the slots placed on the bottom part of the "A" section. Near the upper edge of the main body there are some pre-cut "B" sections which allow - if necessary - a proper opening to let electric wires pass by. Since the height of the box can be considerably changed by its cutting - to be carried out according to the diameter of the spotlight to install as well as its overall dimensions - the cap has been given two different positions ("Q" and "R") where it can be coupled with the box. The box itself can also be reduced if cut along the pre-cut
• the cap (Fig. 5 - 6 - 7 - 8) is adapted to and shaped according to the upper edge of the box main body. Its central stick "F” helps the setting of a possible connection.
• a sealing system “E” surrounds it and is exactly coupled with the application tool (on the "M” area) designed for the fixing procedures. Two plastic tangs define the coupling set-up of the "M” device which can thus be removed, once the box has been fixed into the wall, by simply rotating it in the opposite direction as the one used for coupling.
• the tool for installation (see Fig. 11 - 12 - 13 - 14) is composed of a 3-arm radial device (Fig.
• the radial device is also made up of a cylindrical section, jutting out on the lower side, which is centred and perpendicular to the "L" flat section. There is a “U” locking slot through which the stick shown in Fig. 13 can be easily locked. The upper part of the stick is equipped with an “M” device which locks the box against the "L" flat section.
• the stick placed at the bottom of the box will be applied to an extensible pole so as to create a framework to put in tension between the floor and the ceiling. This way, the installation tool will be supported by it until the fixing procedures are over.
• Three screw anchors can be used as an alternative to the above-mentioned extensible bar in case of extremely high ceilings or whenever the box has to be embedded into a vertical wall. The box can thus be temporarily fixed to the ceiling/wall by means of its special
