    Description


    [0001] The invention relates to a work lamp comprising a lamp housing and a light source and a strap secured to the lamp for temporary attachment of the lamp, said strap having a number of coupling means distributed along the strap. The term "work lamp" does not restrict the invention to be used in connection with crafts; rather it is to be understood as any lamp for temporary use.

    [0002] German published patent application No. 31 16317 discloses a lamp for emergency signalling or the like, which lamp may be suspended by means of a strap attached to the lamp, said strap having a number of slots whereby the strap can be secured on a nail, and moreover, at its end, the strap is provided with a coupling means that can be hooked around the strap itself.

    [0003] Document GB 2 356 448 also shows such a work lamp.

    [0004] The invention concerns a work lamp which, during use, distinguishes itself over the prior art lamp in that it is desirable that the lamp can be secured quickly in such a manner that it can be caused to illuminate a working or other area in a stable manner in any given direction. This is not possible by the prior art technique.

    [0005] The object of the invention is to provide a work lamp that can be secured onto largely all building elements and pointing in any direction, whereby any working area can be illuminated by the lamp.

    [0006] This object is accomplished in that the lamp has at least one coupling means for cooperating with the coupling means along the strap. Since now the strap engages in two locations on the lamp, it is possible to arrange it with various orientations, it being possible to wind the strap around a building part, eg pipes or beams, and subsequently to secure it in two locations on the lamp, whereby it can be fixated in many different positions.

    [0007] For instance, the strap could be integral with the lamp housing, but preferably the strap is secured in a replaceable manner on the lamp, thereby enabling that a new strap can mounted in case the old one should break.

    [0008] According to one embodiment the strap can be secured adjustably. Irrespective of its attachment, the strap is preferably arranged on the back of the lamp housing.

    [0009] The number of options available for arrangement is considerably increased by the strap being elastic. The strap may comprise elastic and relatively inelastic areas, but preferably the strip is configured as a rubber strap. The number of options available for attachment is further increased by the strap being configured with a surface that provides a high degree of frictional resistance.

    [0010] According to a preferred embodiment the strap is configured with open holes, eg quadrangular holes with a pair of opposed internal edges that are essentially in parallel with the strap. Thereby improved fixation is accomplished, and when the strap is elastic the advantage is accomplished that the hole is deformed uniformly thereby facilitating arrangement of the strap on a coupling means on the lamp which is preferably configured as a hook for being received in a hole along the strap. The hook can be configured such that it may cooperate with the strap in different directions for the strap. In accordance with one embodiment it may be a double hook, whereby the strap can be reliably secured in two opposed directions.

    [0011] Alternatively or as a supplement the strap may be provided with protruding studs for receiving one or more holes in the lamp for temporary interconnection thereof to each other.

    [0012] It is not crucial to the invention where on the lamp the coupling means is arranged, but in a preferred embodiment a coupling means is arranged on the front of the lamp housing, whereby the lamp can very easily be fixated on vertical or horizontal building parts. The coupling means on the lamp may also be provided on a bracket which is turnably secured onto the lamp housing, where the bracket may be configured as a handle or a base. Turning of the handle or the base provides further options for arrangement of the lamp in many stable positions.

    [0013] For use in connection with relatively large lamps, a preferred embodiment provides the option of arranging several straps simultaneously on the lamp, in such a manner that each strap is secured in two locations on the lamp. Preferably the coupling means are arranged on the lamp housing in proximity of a connection for an electric wire, said lamp thereby exhibiting the best possible directional stability, meaning that its orientation is preserved even in case a given pull is exerted on the wire.

    [0014] The invention will be explained in further detail in the description of an embodiment with reference to the drawing, wherein:

    Figures 1-8 shows different options available for suspension of the embodiment;



    [0015] The examples of the many options available with the lamp according to the invention are far from exhaustive.

    [0016] Reference is now made to Figure 1 which shows a lamp comprising a lamp housing 1 and comprising a lamp glass, behind which a reflector 2 is located and one or more light sources 3. On the lamp glass, ie the front of the lamp, a hook 4 is provided which is configured to be received in one of the holes shown by 5 in a strap 6 which is preferably made of rubber. The strap is secured onto the rear of the lamp housing as is shown by 7 in Figure 2. Figure 2 shows the lamp suspended around eg a horizontal pipe 8, said strap also being secured to the front of the lamp housing as is shown in Figure 1. Figure 2 shows the lamp suspended vertically below the pipe 8; however, if it desired that the lamp is to shed light eg diagonally upwards, one may wind the strap one more time around the pipe 8, and depending on which hole is used for providing attachment around the hook 4, one may tighten the lamp to shed light diagonally upwards.

    [0017] Figure 2 also shows a handle 9 which is turnably secured to the lamp housing 1 around a journaling, preferably a frictional journaling or a journaling for incremental fixation of the handle in different positions. By a preferred embodiment an electric wire 10 is taken out coaxially with the axis of swinging of the journaling.

    [0018] In Figure 3 the handle 9 is turned upwards, and the strap 6 is attached to the top face of the handle, a hook being provided on the handle identical with the one shown by 4 in Figure 1 (see Figure 4), whereby, during transport of the lamp, the wound wire can be secured by means of the strap 6 as shown in Figure 3. Here, it may also be convenient, albeit not necessary, for the strap 6 to be elastic.

    [0019] Figure 4 shows how the handle 9 is preferably provided with a hook 14 for cooperating with the strap, whereby the strap can be secured against pulls in mutually opposite directions. Figure 4 also shows how the rear of the lamp can be configured with power outlets 13 that may advantageously be arranged like the wire 10, meaning that the orientation of the lamp is not significantly influenced when the electric cables are pulled.

    [0020] Figures 5 and 6 show a further use of the lamp according to the invention where the strap 6 is arranged around a horizontal building part 11. Here the great advantage is shown of providing a hook like the one shown by 4 in Figure 1 on the handle 9, since, by turning of the handle - either incrementally or continuously with friction - it is possible to arrange the lamp in almost any direction around the building part 11. In case of a very heavy lamp it is also an option that the lamp has more than one strap 6, eg two straps that may be arranged in succession in figures 5 and 6. By the embodiments shown in figures 5 and 6 the straps may conveniently exhibit a certain frictional resistance around the building part, and the securing force could be adapted to precisely the requisite degree by adequate tightening of the elastic strap.

    [0021] The term 'work lamp' does not restrict the invention to be advantageous only in connection with the exercise of crafts; rather, the lamp is also suitable for being used as temporary illumination for other purposes. For instance, the example shown in Figure 6 will be extremely suitable for mounting of a number of lamps underneath a canopy where the tube 11 can be a part of the canopy and where the canopy may shelter eg a pavement café or a green stall.

    [0022] By the embodiment shown in Figure 1 the strap 6 is tightened relatively much, whereby the lamp housing 1 is caused to abut on an elongate building part 12. It will be understood that the lamp could be arranged as shown in Figure 1, irrespective of the orientation of the building part 12; albeit, of course, it also depends on the lamp's own weight.

    [0023] Figures 7 and 8 show further examples of how the lamp may be secured, wherein, on the one hand, one uses the function mentioned in the context of Figure 1 to advantage, but also the circumstance that the handle 9 can be used as a further aid in reliably fixating the lamp in many different positions. It will be understood that, instead of the turnable handle 9, it is also an option to use a turnable base, since a base would contribute to the options of attachment in the same way as some of the above-described examples.
