Abstract

Quick snap-on system for lamps comprising a shaped bracket which is to be ceiling or wall mounted and a lamp body so shaped that it can slide on the said bracket, the said lamp body being complete with electric connectors corresponding with one of the said bracket so as to carry out connection between the said connectors.

Description

SPECIFICATION Quick snap-on system for lamps The present invention is referred to a lamp snap-on system, that affords both mechanical and electrical connection of the lamp with one only operation.

According to the usual sequence of installation, when walls and ceilings are built, the electrical cables are laid down into chases, then the plastering surface is finished and the cable ends, necessary to connect the lamp to mains, are left hanging out from the surface.

Now, i.e. the said surface being already completed and painted, the lamp must be mechanically fastened, which usually occurs drilling the wall or the ceiling and inserting expansion plugs into the hole.

Since said drilling operation occurs on a finished surface, it gives rise, of course, to inconvenieces, such as plastering scales brakaway, dirty spots, scratched paint, that often require further expensive reworking and finishing to be made. The same occurs, when, for any reason, the position of a hole turns out to be wrong or, after examining the impression produced by the installed lamp, it is decided to shift it even by little.

Similar inconveniences can also arise when the lamp is electrically connected.

Another characteristic of the current installing systems is that the replacement of a lamp having any fault you like, from the burnt-out fluorescent pipe to the outer case damaged by impacts or similar, requires the lamp to be dismounted or at least opened, which can give rise to difficulties, especially if the lamp is found at a position hard to approach.

If the lamp body must be dismounted too, the mechanical fastening to the wall or ceiling is therefore concerned, as well as the electrical connection, further damages to the plastered and finished surface being thus at stake.

Object of the present invention is to afford a quick snap-on system for lamps, suited to connect a lamp to a bracket with one only easy operation, said bracket acting as both mechanical and electrical connection. Said bracket can be fastened to the wall or ceiling before surface finishing; it furthermore bears an electrical connector, that, as better explained below, enables both lamp and external cables to be connected. In this way, the above listed inconveniences are avoided, since all operations for both mechanical fastening and electric connection of brackets can be carried out on the rough surface, whilst jeopardizing neither plastering nor painting. Even if one or more fastening holes have been wrongly positioned, making up a unfinished surface is surely easier and cheaper than reworking a finished one.

Furthermore, if a burnt-out light source (lamps or fluorescent pipe) must be replaced or need an intervention because of damages or similar occurring on the lamp body, after the wall surface has been finished, an easy operation will suffice to disconnect the lamp body from the bracket; the lamp will be released and it will be possible to repair it under the best conditions, since the lamp is no more engaged in its usual support.

Further objects and advantages will result from the following attached sheet, that shows diagramatically and by way of example a preferred embodiment of this invention.

Referring to the said sheet, Figure 1 shows the bracket 1 having an external profile purposely shaped and bearing also a male connector 2 for the electric connection to the lamp and to the outer wiring through screw clamps.

Holes have been purposely drilled from the said bracket 1 for wall or ceiling mounting, using the screws 5, 6 and 7 or similar fasteners; other slots have been machined from the bracket, enabling the connectors to enter in different ways.

Figure 2 shows the lamp body 3, bearing opposite shaped projecting parts, that facilitate the longitudinal slipping in/off of the lamp body on the bracket and at the same time prevent it from transversally and perpendicularly moving. The said body 3 in turn bears the diffusion screen.

The lamp body 3 is longitudinally blocked using a latch-type device, the spring pawl 8 of which is machined from the said bracket 1.

The female connector 4 is found at the lamp body rear. The whole group can be engaged and secured, by simply positioning and then longitudinally shifting it on the bracket. At last, it is possible to prevent unauthorized persons from removing the lamp from the bracket, using a screw for fastening the lamp body, with such a length, that it interferes with the sliding motion between the lamp and the bracket. The present invention, diagramatically illustrated and described by way of example with particular reference to the attached sheets, should be meant as extensive to all those collateral versions, that, as such, are included within the framework thereof. In fact, the materials used in the practical execution can be of any kind depending on the particular requirements, without going beyond the scope of the following claims.
