Definitions

the invention relates to a winding device with a guide device, by means of which a Traction means on a cylindrical lateral surface one relative to its axis Guide device rotatable coil is conductive and can be received on this lateral surface.
Such a winding device for receiving the suspension cable is generally known Mains voltage operated pendant lamp, with the suspension cable inside the spiral winding power cord for power supply of the pendant lamp is guided.
Such winding devices are usually used for optical reasons Ceiling connection of the pendant lamp, for example hidden under a suspended ceiling. With a pendant light intended for mounting on a standard ceiling hook the winding device is usually in this hook and the power supply concealed cover integrated - which inevitably makes this cover significantly larger is compared to comparable lights without height adjustment.
the known winding device consists essentially of a horizontally lying Coil for receiving the suspension cable in one - except for an inlet opening for the suspension cable in the bottom - closed plastic housing.
This is in this plastic housing Support rope wound up or unwound by rotating the spool about its axis, one on Housing and coil attached torsion spring of the weight of the lamp body in the Mainly keeps the balance. In this way, the lamp body - inside of the area specified by the length of the suspension cable - to any height without high effort can be set.
the known winding devices are in the field of low-voltage lighting technology hardly usable due to the striking dimensions.
the object of the invention is to propose a winding device, which due to its Dimensions suitable for height adjustment of a low-voltage pendant lamp and with one to connect such optically advantageous.
this task is accomplished by the Invention solved in that the axis of the coil is aligned in the direction in which the Traction means when entering the winding device.
the Winding device in the direction of the traction means particularly slim - and in the case of Pendant lamp can be designed visually particularly appealing.
the coil is in the direction of its axis designed to be movable relative to the guide device. So the turns of the traction device can the coil are taken up axially offset.
a forced coupling of the rotation and translation movement of the coil relative to the Guide device is in without additional mechanical components by interlocking threads a contact surface of both components can be realized. Will the pitch of the thread selected (at least slightly) larger than the diameter of the traction device, then successive turns of the traction means next to each other in a particularly simple manner placed on the spool.
the number of components of the winding device according to the invention can be kept low if the thread on the outer surface of the coil and on an inner Cylinder surface of a guide device encompassing the coil. Will be here (as described above) the pitch of the thread is greater than the diameter of the If the traction means is selected, it is placed in the threads in a targeted manner. Should be two separate traction devices are placed simultaneously on the same spool - for example hot a low-voltage halogen pendant lamp hanging on two conductors - is this thread particularly advantageous to perform two-course.
the guide device has a mandrel with a Thread on the outside, which is in engagement with an internal thread of the coil.
the traction means is then preferably on a non-profiled outer surface of the coil added.
the mandrel can reduce manufacturing costs in one operation with molded thread by injection molding from a thermoplastic getting produced.
- metal for example Aluminum
colored glass - are used.
the winding device is preferred - particularly when used for height adjustment a pendant lamp - equipped with a drive device that requires manual intervention on the winding device for winding or unwinding the traction means.
a winding can also be used here Torsion spring can be used, the balance of a tensile force in the traction means.
the winding and unwinding of the traction device is then changed by a slight change Traction - for example by slightly lifting the luminaire body of a pendant luminaire Gear set.
Another embodiment has - alternatively or in addition to the torsion spring Motor on, for example, controlled by an integrated in the winding device Logic circuit and an optical sensor a contactless winding and unwinding Traction means - for example for height adjustment of a pendant lamp - made possible.
Traction means first through the coil and only then through the guide to the Guided surface of the coil.
Traction means first through the coil and only then through the guide to the Guided surface of the coil.
the winding device according to the invention can be used in particular for height adjustment a pendant lamp. Because of the longitudinal axis of the in the direction of the traction device Coil, the winding device is optically particularly advantageous in the typical filigree To integrate the construction of a low-voltage lamp.
Luminaire carrying traction means is an electrical cable used to power the luminaire, especially if both conductors are integrated in it - the use of one is preferred here Coaxial cable. If a coaxial cable that is not insulated from the outside is used, it can the luminaire can be combined particularly easily with a touch dimmer as it is made of DE 196 28 891 is known.
Figures 1 to 3, 4 to 6 and 7 show three different, with the reference numerals 1, 23 and 46 designated embodiments of the winding device according to the invention Height adjustment of a pendant lamp using low-voltage halogen technology.
the winding device 1, 23, 46 essentially consists of a coil 2, 24, 47 and a guide device 3, 25, 48 which are rotatable relative to one another and movable in the direction of the coil axis 4, 26, 49, these movements by a single thread 5, 27 (not shown on the Winding device 46) are coupled with a slope of about 4 mm.
the winding device 1, 23 has a torsion spring 6, 28 (not shown on the winding device 46), which at one end with the Guide device 3, 25, 48 and connected at the opposite end to the coil 2, 24, 47 is.
the winding device 1, 23 is with a lamp body 7, 29 to a structural Unit summarized.
