Description

Luminaire with screwless attachment to a fastening surface

The invention relates to a luminaire with screwless attachment to a mounting surface according to the preamble of patent claim 1.

An attachment, however, only for screwless attachment of a lamp body has become known with the subject of DE 20 2004 003 640 U1. In this known luminaire body attachment of the lamp socket forms a screw thread with an external thread, which passes through a lamp body and engages in an internal thread in a luminaire reflector, which is thus held exciting against the lamp body.

From this document, however, it is not apparent how the light socket is attached to a mounting surface, in particular can not be removed a screwless mounting the light socket on a mounting surface.

Although a screwless attachment of an adapter part is shown in a receiving part with the subject of DE 33 08 306 C2, but can not be seen from this document as the adapter part itself is screwless attached to a mounting surface.

The invention is therefore the object of developing a lamp of the type mentioned so that a screwless attachment to a mounting surface is possible.

To achieve the object, the invention is characterized in that the lamp consists essentially of a lamp socket whose outer circumference is at least partially designed as a latching, clamping or screwing means, said locking, clamping or screw means in an associated latching , Clamping or screwing on the inner circumference of a clamping element engages, which is displaceable in the longitudinal direction of the lamp displaceable against a mounting surface or screwed. With the given technical teaching results in the significant advantage that now a solid, non-positive and positive fastening of the said light on any mounting surface is possible. It requires no screws or other fasteners, with the exception of a hook or other holding means, which is arranged in the mounting surface.

In a preferred embodiment of the present invention, it is provided that the lamp holder is connected to a holding band, which is designed as an elongate element for suspending the lamp holder from the mounting surface.

Such a retaining band can for example consist of a plastic band, of a metal band, of a plastic band provided with holes, of a textile band, and of any other, band-shaped or otherwise profiled holding bodies. Instead of a tether other suspension elements can be used, such. As a kinkable or breakable support rod, a spiral or coil spring or any other suspension or holding body, which is variable in length.

In a preferred embodiment of the invention, however, a tether with individual spaced-apart holes is described below, because this is a very simple embodiment. However, the invention is not limited thereto. There are all suspension or holding body, which are variable in length, claimed.

In the simple, previously described embodiment, it is now provided that initially in a mounting surface (which may be inclined vertically, horizontally or in any direction), a hook or other retaining element is screwed, driven or otherwise secured, which retaining element (hook ) is inserted into an associated hole of the tether.

The clamping element is now placed on the outer circumference of the lamp holder, wherein the diameter of the clamping element with respect to the lamp holder is formed so that the clamping element forms an inner receiving opening, in which the lamp holder can be accommodated as positively as possible. It is important, however, that between the inner circumference of the clamping element and the outer periphery of the lamp holder corresponding locking, holding or screw means are arranged to form the two parts height adjustable to each other.

In a preferred embodiment, a screw connection between the inner circumference of the clamping element and the outer circumference of the lamp socket is described below. However, it will be explained in more detail below that the invention is not limited thereto.

When using corresponding interlocking threads, it is now provided that when the lamp holder is held, the clamping element is screwed onto the lamp socket and rests with its upper, near-face end face on the mounting surface. Before this screwing is completed, however, it is provided that the retaining strap is shortened suspended on the hooking element (hook) in order to achieve the smallest possible screw spacing between the upper end face of the clamping element and the associated mounting surface.

At this stage (or before), the electrical connections between the ceiling-side lines and the electrical leads of the lamp socket can be made.

In this case, it is preferable to provide a screwless installation even for these connections. There are various clamps or jacks known to work without screws.

If the electrical connection between the ceiling-side line and the lamp-holder-side line was made, the clamping element can now - while holding the lamp holder - are screwed further against the mounting surface until the upper, near the ceiling end face abuts the mounting surface. It thereby creates a clamped connection, because at the same time the tether is clamped against the lamp holder and the lamp holder thereby tilted, firmly and resiliently biased against the Attachment surface is pressed. Such spring preload is always given when the tether is resiliently formed.

In another embodiment, however, it may also be provided that the tether consists of chain links or other elements that are not elastic. In this case, the elastic bias would then be achieved by the suspension characteristics of the hook and the like.

Of course, the invention is not limited to a positive, resilient bias of the clamping element on the mounting surface. It can also be provided that the clamping element does not bear with its upper end face on the mounting surface, but occupies a certain distance from this mounting surface.

In another embodiment, it may also be provided that the upper end face of the clamping element forms an angle to the mounting surface so as to attach the entire lamp at an angle to the mounting surface.

It is important in all embodiments that with the lamp according to the invention now for the first time a completely screwless mounting a lamp holder is provided on a mounting surface, without any additional mounting aids are needed.

Thus, the invention is not dependent on that the clamping element is designed as a clamping cylinder and a corresponding screw connection between the inner circumference of the screw cylinder and the outer periphery of the likewise cylindrically shaped lamp socket takes place. It can be used all other arbitrary profile shapes for the clamping element and a correspondingly adapted profile for the lamp socket.

In particular, rectangular, square, oval or other non-circular profiles can be used, provided that the lamp holder fits with its profile shape in an adapted inner profile shape of the clamping element. It follows that the outer profile of the clamping element can be quite different from the inner profile of the clamping element, because it only matters that the outer profile of the lamp holder is adapted to the inner profile of the clamping element.

With regard to the choice of material of the funds used free design options is given. It can be used for the clamping element of any material, in particular metal, wood, plastics or composites of the materials mentioned are used. Likewise, ceramic materials can be used for the clamping element and for the lamp holder.

Also, the choice of the bulb is completely arbitrary. It can be used conventional lamps based on filament lamps, as well as halogen lamps or other bulbs. Of course, it can also be provided that the lamp holder is not used as a screw socket (eg E27 or E14), but it can also jacks for the insertion of halogen bulbs are used.

Likewise, the said luminaire arrangement can be used for a single-capped fluorescent tube.

The advantage of the said luminaire consists in the fact that a solid attachment to any mounting surface succeeds without tools and that such a lamp is particularly easy to assemble and disassemble. It can be subjected to arbitrary designs in their exterior design and the choice of material of the clamping element, which is substantially visible from the outside, can be designed arbitrarily.

Of course, it is also possible to form such a clamping element as a glass cylinder, ceramic cylinder or the like. It is also possible to make the clamping element transparent, in order to achieve a certain lighting effect. The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

In Figures 1 to 9, a lamp 1 is generally described with a cylindrical clamping element 2, which cooperates with a likewise cylindrical lamp socket 5.

In the illustrated embodiment according to Figures 2 and 5, the lamp holder 5 is preferably in a conventional manner from a metal cylinder, the one

Internal thread 7aufweist, in which a known light source 8 is screwed. The contact parts on the inside of the

Lampholder 5 are not shown.

The outer circumference of the lamp holder 5 carries in the exemplary embodiment, an external thread 6, which cooperates with an associated internal thread 3 on the inner circumference of the clamping element 2.

The lamp holder 5 is otherwise connected to a holding band 9, which is preferably designed as a flexible perforated belt and which is hooked with its upper hole 10 in an associated cover 17 attached to the hook side.

Furthermore, the connecting lead 11 is led out of the lamp holder 5, which terminates in an associated connecting terminal 12.

In the embodiment according to FIG. 3, the clamping element 2 having an internal thread 3 is now screwed onto the lamp holder 5, so that the combination according to FIG. 1 results.

Thus, the lamp holder 5 does not twist during the screws of the clamping element 2, for example in the direction of rotation 21, the lamp holder carries on its lower side a retaining edge 15 of increased diameter, which can be grasped by hand. Thus, the clamping element 2 is placed on lamp holder 5 and screwed in the direction of arrow 21, so that the clamping element 2 in the direction of arrow 13 moves upward and at the same time the upper end face 14 of the clamping element 2 of the mounting surface 16 on a ceiling, side wall or any other inclined mounting surface approaches.

In the intermediate space between the operation of Figure 6 and Figure 7, it is provided that, first, before the screwing of the clamping element 2 in the direction of arrow 13, the ceiling-side distance of the lamp holder is changed in order to achieve a ceiling as close as possible. In this state, the ceiling-side wires 19 are inserted into the terminal 12 and electrically connected.

It is thus achieved the mounting state of Figure 7.

With further screwing of the clamping element 2 while holding the lamp holder 5, then the end face 14 forms positive and non-positive on the mounting surface 16 and thus results in a completely safe tilt-free and biased holding compound on the mounting surface 16th

FIG. 9 shows the completely assembled luminaire, wherein it can be seen that only the decoratively designed clamping element 2 is visible from the outside and that the lampholder 5 protrudes only slightly from the underside of the clamping element 2.

However, it can also be provided in a development of the invention according to FIG 4, that on the outer circumference of the clamping element 2, an external thread 20 or other receiving device for holding a lampshade or the like is provided.

It is explained with reference to FIG. 10 that the profile shape of the clamping element 2 and the lamp socket 5 does not matter. It can arbitrarily profiled parts 2, 5 are inserted into each other, provided that the outer periphery of the lamp holder 5 is held exciting and adjustable in height in the inner circumference of the clamping element 2. Here, the embodiment of Figure 10 shows that about a square or rectangular profiled lamp holder 25 is provided on its outer periphery with outwardly projecting locking means 23, said locking means, for. B. protruding locking knobs, barbs or other holding elements can be.

These latching means 23 cooperate with associated, complementary locking means 24 on the inner circumference of the clamping element 22, wherein this clamping element corresponds at least in its interior design of the profile shape of the lamp holder 25.

In this way, the latching means 23 cooperate with the latching means 24 and when pushing the clamping element 22 from the bottom of the lamp holder (arrow 18) then sets the clamping element 22 (not shown) also form-fitting manner to the mounting surface 16, where provided is that here again (not shown in the drawing) a suspension of the lamp holder 25 of the mounting surface by means of a tether 9 or the like is present.

For the sake of better graphic representation, the two parts 22, 25 are drawn apart, because they are in the assembled position in mutual detent engagement and in this case the upper end face 14 of the clamping element 22 rests against the bonding surface 16.

Instead of the releasable latching means 23, 24, it may also be provided in another embodiment that non-releasable latching means (barbs) are used.

Instead of latching locking means and non-latching clamping means can be used, such. B. elastomeric frictional connection, wherein z. B. on the outer circumference of the lamp holder one or more O-rings are arranged, which arrive in associated Reibschlusseingriff with the smooth inner circumference (or also grooved inner circumference) on the inside of the clamping element 22.

Instead of the latching engagement thus a frictional engagement between the clamping element 22 and the lamp holder 25 is described. Zeichnunqsleqende
