Built-in box for mounting in a wall, ceiling or bad element

The present invention relates to a built-in box for mounting in a wall, ceiling or other element.

When mounting electrical equipment in a wall, in ceilings or other elements, such as in kitchen cabinets, bookshelves, shelves and the like, the mounting usually takes place in a cavity provided in the element using a box or can, subsequently referred to as a can. The electrical wiring connections are usually routed through suitable piping systems to junction boxes or boxes, on which electrical equipment, such as lamps, switches, etc., is arranged, for example, as a lid on the electrical junction box. In particular, in the case of lamps, the socket is usually arranged in a conduit connection extending through an opening in the lid of the electrical junction box in such a way that there is a physical distance between the electrical junction box and the lamp base. In other types of lamps, especially in so-called built-in spotlights, a diaphragm ceiling is arranged at a distance from the underside of a horizontal floor separation between two floors. Holes in which the spotlights are arranged are drilled in the aperture ceiling. On the upper side of the aperture ceiling, the wiring connections are forwarded to junction boxes which are attached to the underside of the horizontal floor separation so that the built-in spotlights can be electrically energized. An example of such a junction box is disclosed in US6168299.

Another prior art example is disclosed in applicant's prior international patent application WO2005059435, which discloses an apparatus suitable for mounting in a ceiling or the like comprising a housing, the housing having a lower cylindrical section and a lid mounted at one end. of the cylindrical section, the opposite end of the cylindrical section being open. On the outer periphery of the cylindrical section, a plurality of protruding spring means are provided for securing and holding the apparatus at the desired location.

In buildings where a recessed aperture cannot be fitted, organs may be inserted at the rear of the aperture for the purpose of recording the recessed spotlights. A number of factors must be taken into account in providing such a construction. Among other things, insulation placed immediately on / near the aperture ceiling, as well as a moisture barrier (moisture barrier film) must be taken into account, and appropriate measures must be taken to ensure that the moisture barrier (moisture barrier film) remains intact, as well. the insulation must be properly arranged around the built-in spotlight holder.

A further problem associated with built-in spotlights concerns, in particular, the heat generated by halogen lamps, which are predominant in interior design, especially in department stores and stores. In order to minimize fire danger, it is desirable to ensure that the temperature behind the halogen light sources does not reach a level where there is a real risk of ignition of flammable material present in the built-in halogen spotlight. Generally, the manufacturers of recessed halogen spotlights indicate that no combustible material should be placed closer than 50 cm from such luminaires in order to avoid a risk of fire. From some suppliers of electrical equipment, the corresponding clay is that the temperature in the vicinity of the electrical equipment is not allowed to exceed 90 ° C in order not to damage the electrical equipment and thereby make the electrical equipment a source of fire danger.

A prior art apparatus comprising means for cooling the electrical equipment is disclosed in US5664872. This apparatus comprises two sections which must be connected so that the electrical connections are first completed, and then a fan unit is attached to the junction box, where upon activation the fan 20 passes air to pass the electrical installation. The junction box is arranged to be citrated in, for example, a ceiling, and then the light fixture is mounted by means of a sleeve or collar, which can snap-lock into a flange on the junction box to provide such a final impression as is necessary in this case. type of installation when installation takes place at an exhibition interior. The installation requires a number of parts, and once the junction box and electrical wiring are located, it is impossible to access the fan unit from the underside of the ceiling. The cleaning and maintenance of the unit is therefore very difficult, as a complete dismantling of the unit is required to gain access to the unit.

30

Furthermore, prior art apparatus are all designed for use with only one particular type of light source, each prior art apparatus being provided with only one particular type of base. In addition, for a number of applications, such electrical installation equipment is required to be approved by national authorities, and most manufacturers are therefore reluctant in this regard to obtain approval for series of appliances according to the prior art suitable for different light sources.

Therefore, it is a task of the present invention to provide a built-in box suitable for placement in a wall, ceiling, furniture element or other element in which an electrical installation member, such as a lamp base or the like, can be attached without causing the built-in box to cause any of the aforementioned problems or risks. Furthermore, the built-in box must be adaptable for recording, in a standardized way, from different light sources.

The present invention solves this problem by providing a built-in box of the kind mentioned above, wherein the housing box comprises a housing, the housing comprising a pipe section, an end cover, where this end cover and an end of the tube are provided with releasable collecting means. and wherein the opposite end of the pipe is open, and wherein the built-in box comprises means arranged externally with respect to the pipe, and which means are expandable outside the outer periphery of the built-in box, and where socket means and electrical connecting means are provided in said end cover.

By arranging separate elements, viz. the pipe section and the end cover, it is possible to use the pipe section as a standard element for mounting a variety of different types of light fixtures, in that the end cover comprising the socket and the electrical connection means can be selected according to the desired light source. In this way, it is possible to standardize the mounting of recessed boxes independently of the type of light source desired for a particular position. The different types of light sources also require different sources of energy in most situations, and therefore, by using a standardized pipe means, the physical mounting in the (receiving) element, for example in a ceiling, wall or the like, can be performed routinely, and the electrical connections can also be established routinely and independently of the energy source, which applies in the particular position.

For example, the attachment between the end cap and the tube may be established in the form of a so-called bayonet connection, in which flanges are arranged along a portion of the periphery extending from the end cap, and where a portion of the flanges is inserted into suitable slots formed at the end. of the tube, and when rotating the end cap relative to the tube, the flanges will thereby engage the tube end, thereby securely and reliably retaining the tube relative to the end cap. As an option, adhesives, threads, snap-locking devices, or other fasteners may be arranged between the two elements between the two elements.

In a further advantageous embodiment, the end cover on the side which faces away from the interior of the pipe is equipped with an electrical junction box, which can be selected to correspond to the respective required energy, power supply, or power source.

Typically, from the authoritative point of view, claims will be made for environmental protection measures against possible electric shocks, especially when connecting wires are used. For this purpose, in the case of a standardized junction box suitable for this purpose and specifically made for attachment to the end cover, it is possible to use a standard junction box which can be of any type of connection type, thereby providing a secure and approved construction provided using standard elements, thereby providing the built-in box of the present invention.

In yet another advantageous embodiment, a double hinge is pivotally attached to the end cover, the hinge comprising flange means for attaching electrical components such as one or more of: transformers, electrical switches, remote control circuits, cooling or ventilation means.

Since the recessed box provides the possibility of mounting the total lysamature from the side from which the light should be visible, only one opening is required which is only slightly larger than the recessed box. As a result, all components must pass through this opening, which is associated with the installation as such. The dual hinge mechanism provides the possibility of using long-like elements, such as a transformer or the like, which, mounted on the hinge means, can pass through the opening in the element prior to insertion of the built-in box. The hinging mechanism will therefore ensure that components such as, for example, an electric transformer, an electrical switch, a remote control circuit, cooling and / or ventilation means are located immediately at the rear of the element, so that the overall design height is kept to a minimum.

It is also possible to have the double hinge attachment mounted on the pipe element.

It will be appreciated that the aforementioned electrical components do not, by being mentioned, act to limit the number or types of electrical components suitable for use in connection with the double hinge.

The expandable means established outside the outer periphery of the built-in box, for example in the form of resilient means intended for attaching the built-in box, do not require special tools for this, in some embodiments the resilient means will be deformed when the built-in box is placed and when the built-in box is placed. having reached final position, the resilient members will deform (flip) back to the original position and shape, thus holding the built-in box in position.

Furthermore, by using resilient means, whether or not they are in the form of similar elements or in the form of coherently deformable elements or sections in the recessed box, a secure and further customizable fastening method is provided. Since the circumstances of building components can vary from installation site to installation site, it provides the advantageous use of resilient means, i.e. of adaptable fasteners, the possibility of reliably mounting the built-in box in different materials and under different circumstances. This greatly reduces the risk of installation errors.

In a further advantageous embodiment of the built-in box according to the present invention, a ventilation means is provided at the opposite end of the built-in box relative to the opening. By installing ventilation means at the end of the built-in box which is opposite the opening, the interior of the built-in box becomes completely free, and therefore any electrical installation can be installed without interfering with the ventilating means.

In a further advantageous embodiment, the end of the built-in box comprises one or more openings for the entry or exit of air to or from the built-in box. In order to enable the built-in box to compensate for differences in pressure caused by the ventilation means, openings can be arranged so that the inside of the built-in box communicates with the ambient air.

6 DK 2010 00167 U4

In a further advantageous embodiment according to the invention, the ventilation means is a fan comprising a ventilation generating means, and where, optionally, the electrical installation power supply also supplies power to the ventilation means.

Furthermore, for the ventilation generating means, fan cooling ribs, such as aluminum ribs, may be provided. Although condensation often occurs due to cold aluminum surfaces, however, the air generated by the fan will carry away any moisture and as a result condensation problems are avoided.

For low voltage installations, such as those for 12 or 24 volts, it is possible to purchase fans which have a very low energy consumption and which, in order to provide a cooling effect, will be able to produce a sufficient air flow. The energy consumption for this is negligible in comparison with the energy consumption for the light sources, and in addition, the extra heat generated by the fan is also meaningless in comparison with the air flow which can be conducted through the interior of the built-in box. At other voltages, such as 110 volts or 230 volts, either suitable fan means or a transformer may be placed in the circuit so that the fan is provided with appropriate current and voltage. Thus, this device assumes that no additional installations or implementations will be required to supply energy to these ventilation devices, the built-in box being specially adapted for use in electrical installations, and therefore there will be bodies present in the built-in box for providing electrical energy supply, and this will therefore be available to the ventilation generating energy supply.

In a further advantageous embodiment, the side of the end facing away from the opening is equipped with spacer means such as, for example, legs, projections, net curves or the like. In circumstances where the built-in box according to the manufacture is installed in ceilings, where the ceiling structure comprises a visible ceiling covering, behind which a moisture barrier is arranged, behind which insulation, such as a soft glass wool, is provided, the built-in box is provided with spacers. thereby providing air to the fan, in order to produce a cooling air flow down through the built-in box to provide cooling of the electrical installation located inside the built-in box.

These spacers may also include a filter so that dust and other particles are not transported into the room via the built-in box.

By using ventilation generating means such as, for example, a low voltage fan which is comparable to the fans commonly used in PCs, an advantageous embodiment can be obtained. These types of fans have a life expectancy of up to 200,000 hours, constant at 70 ° C. Tests carried out with the present invention have shown that with a design in which a 35 W halogen light source of type Osram Decostar was placed inside the built-in box, the temperature above the light source connected to and around the connection lines reached and stabilized. at 91 ° C for this 35 W halogen light source. After installing a fan of the above type used in PCs, the temperature near the light source was reduced to 54.6 ° C and around the cabling the temperature was measured and stabilized around 32 ° C. The measured temperatures remained , after completion of an initial period, stable during the trial, which lasted more than four hours.

Lowering the temperature has a number of beneficial effects. First of all, the life expectancy of the light source can be increased and at the same time the risk of fire in the immediate vicinity of the installation is dramatically reduced. Furthermore, by arranging the fan so that the air flow is directed into the room in which the light is emitted, the heat generated by the light source and the fan is vented into the room and allowed to be used for heating. Furthermore, since hot air is lighter than cold air, the amount of hot air produced to obtain a comfortable temperature in the residence zone can be reduced, as the light source, due to the presence of the fans, will produce an air circulation in the immediate vicinity of the ceiling, so that the hot air that accumulates along the ceiling will be forced downward as a result of the air flows generated by the cooling fans.

In yet another advantageous design according to the invention, the built-in box is provided with means for attaching electrical installation means, and furthermore, additional means are provided to enable the air flow produced by the ventilation means to pass the electrical installation means.

The invention will now be described in more detail with reference to the drawing, in which: FIG. 1 is a diagrammatic view of the box with the parts pulled apart; FIG. 2 is a schematic representation of an integral box in overall condition; and FIG. 3 shows a cross-section through a recessed mounting position.

10 In FIG. 1, with the parts of the housing box shown drawn apart, a housing box found according to the present invention is shown. The built-in box comprises a pipe element 1, an end cap 2, an electrical junction box 3, flexible and / or resilient extensible means (s) 4, a double hinge structure 5, which in this configuration is equipped with a transformer 6 as well as a lid part 7 .

The lid part is designed to be mounted when the complete built-in box and its connections are installed in place via an opening in an element, so that the lid part 7 will cover the opening and around the built-in box provide an aesthetic appearance to the surroundings.

The pipe element 1 may be cylindrical in shape, but is not necessarily, and in the embodiment shown, is provided with an opening at both ends, as described in connection with the other drawing figures. The double-hinge mechanism 5 is arranged with two hinge locations 8, 9 so that hinge flanges 10, 11 are pivotally arranged so that the flange 11 can be brought into a position where it extends in the same direction as the tube 1. In this way it is possible to install the entire installation through an opening in an element which exhibits a size corresponding to the outside diameter of the pipe 1.

The end cover 2 is provided with a plurality of flanges 13, 14, which can engage with corresponding recesses in the end top 15 of the pipe element, so that, after placement of the flange elements 13, 14 in the openings arranged at the end of the pipe element 1 and twisting of the end plate 2, a strong connection between the end plate 2 and the tube 1.

By assembling the parts with reference to FIG. 1, a built-in box as shown in FIG. 2. In this embodiment, the number "18" written on the tubular body 1 indicates the thickness of the plate element into which the built-in box can be mounted. With this configuration, it is ensured that the transformer 6 will be placed in a substantially horizontal position. This can be adjusted by the length of the flange 10 or the length of projections 20 arranged on the second flange 11.

The flange 11 can advantageously be provided with semicircular projections. These serve to prevent the flange from being entangled in wires, cables or the like located on the back of the element in which the built-in box is mounted. Also, when the built-in box is mounted in wooden ceilings, the projections will act as sledging means which help the flange and thus the built-in box to pass openings, grooves and the like that may be present on the surface.

With respect to the fastening means 4, it can be seen that by downward movement of the element 21, the end 22 of the resilient member 23 will cooperate with the fastening means 24 to project it out of the periphery of the tube 1, thus enabling engagement with the the back of the plate element into which the built-in box must be fitted.

In FIG. 3, an embodiment is shown in which the drying element is shown cut away so that only the lid part 7, the hinge 5, the transformer 6, the end plate 2, fastening means 4 and the connecting box 3 are visible. The junction box can be adapted to accommodate installations for voltages of 12, 24, 110, 220 or any other voltage value, and in this embodiment is provided with pins 25 such that a distance between the end plate 2 and the junction box is maintained. 3, so that heat generated by the light fixture is not immediately transferred to the electrical connection means.

Furthermore, as can be seen, the cover plate 7 is arranged inside the pipe element not shown by means of resilient means in the form of springs 26, so that variations in the plate thickness "a" can be compensated by adjusting the distance by which the cover plate 7 is inserted into the pipe element. 1. Inside the pipe member 5 cams and grooves / grooves may be provided for retaining the resilient members 26 in the desired position. The upper end of the spring 26 may be provided with a tip. The cam or grooves arranged on the inside of the ear member may be formed as a thread so that the tips of the springs engage with the thread. When rotating the cover plate, the tips will move up or down depending on the orientation of the threads 10 and the direction of rotation, thereby enabling accurate positioning of the cover plate relative to the surface in which the built-in box is fitted.

On the underside of the end plate member 2 (when assembled it is on the inside of the pipe element) there may be provided a suitable socket (solder) intended for receiving a desired illuminating body, such as a socket type GU 10, which is suitable for serving as a halogen light fixture, or, for example, standard 220V sockets
