Definitions

  • the invention relates to a pendant lamp with traction drive according to the preamble of the claim 1.
  • Pendant lights with traction drive enable the Setting different heights of your lights by one arranged in the suspension of the traction device Mechanics.
  • a spring mechanism in which the Drum axis connected with a coil spring in this way is that when unwinding the traction device, the drum the spring winds up, e.g. one over one Free-running brake engages as soon as the Winding the spring stops the necessary tensile force. This brake could be released when pulled again , which then pulls through the force of the spring is wound on the drum.
  • the Pendant lamp can also be set so that the weight of the free end of the traction device and the attached lamp is sufficient to the To hold the lamp in a predetermined position, but the traction device winds up when the lamp is raised becomes.
  • textile coated can be used as the traction means and therefore relatively thick and soft cable be used.
  • the invention is preferred however applicable to cables that meet the modern standard correspond and a homogeneous, preferably have made of plastic, the better protects the cable against wear, however whose flexibility more or less diminishes.
  • Such traction devices are usually thinner cable covered as textile.
  • pulling means are also suitable according to the invention, which are not used as electrical leads but mostly with a plastic sheathed cables existing electrical Interact supply line, in which the cable with preformed turns the traction device as a spiral surrounds.
  • From DE-C-149 954 is a pendant lamp with traction drive by a Known drum, wherein the drum has a conical basic shape and provided with a spiral-shaped groove on its outer casing is. An orderly winding of the traction device on the drum should by spiral-shaped groove can be guaranteed, in which otherwise unguided traction means, if properly operated, also become helical rolls up.
  • the conical basic shape of the drum is intended to be a changing torque of a spring device driving the drum to compensate.
  • a pendant lamp with traction drive to be provided by a drum, with orderly winding the traction device is supported on the drum.
  • This is the direction of the downforce the following movement of the envelopes is wanted and is by tuning their main influencing factors consecutively chosen so that the many envelopes all tight on the drum and Put them together evenly.
  • the Ease of use is essential and prevents that Mechanical failure due to irregular envelopes of the traction device around the drum.
  • the invention has the advantage that it is advantageous Effects regardless of the type of Achieve traction means and its structure and thereby especially the desired plastic cable as Use traction devices despite their inflexibility can without the convenience of the mechanics suffers.
  • the invention is suitable in this embodiment also for traction devices that differ from the actual one Supply cable separated as described at the beginning are. However, the invention is preferred with the Features of claim 3 realized to the modern Standard for such pendant lights too correspond.
  • the invention also has the consequence that because of the conical Drum envelopes around the little ones Save the drum diameter of shorter traction lengths than the envelopes around the larger drum diameters. Because you have envelopes on top of each other of the traction means also in the conical according to the invention Drum coats in the interest of a smooth-running Avoid retraction mechanism, on the other hand should keep the size of the drum small, because the drums are otherwise difficult to mount in the ceiling can be accommodated by pendant lights, is the embodiment according to claim 4 many times preferable. This is because the larger drum diameter in the cylindrical part of the drum continued. Its axial length, however, should only be slight to skip traction envelopes to prevent. For such embodiments the features of claim 5 are provided.
  • the actual lamp with lamp is in the drawings not reproduced.
  • the power supply to Lamp is made by the traction device 1 (Fig. 1), which encased as a relatively inflexible plastic Cable is formed.
  • traction device for the traction device is a provided generally designated 2 traction drive, partially inside a drum 3 is housed.
  • To hold drive 2 and Drum 3 serves a housing 4, which with a Canopy 5 is covered.
  • the feed line 6 is inside the canopy and won't with one shown cable clamp connected.
  • the housing points in the lower, i.e. removed from the ceiling 7a Area a closed funnel 7, through its larger opening 8, the feed line 1 is inserted is.
  • the smaller opening 9 from which the Traction device 1 exits, guides the traction device, i.e. steers it regardless of the direction of pull that is in Fig. 4 is indicated by an arrow 10 with the Canopy tip on the drum.
  • the drum 3 has a conical jacket 11 and is designed according to FIG. 5 as a solid molded body. According to the exemplary embodiment in FIG. 5 is the angle of inclination of the drum shell 11 30 degrees.
  • the traction device guide 9 is below the in Fig. 2 last traction envelope 12. Die Surface of the plastic cable 11 is as well the surface of the drum shell smooth and with the 30 degree inclination angle of the drum casing 11 and the arrangement of the traction device guide 9 in this way voted that the envelopes 12 to 17 on the drum slope 18 each the neighboring envelope create, as shown in Fig. 2.
  • drum casing 11 cylindro-conical, i.e. to the drum slope 18 (Fig. 1) closes a cylindrical Sheath section 19.
  • the cylindrical part 19 of the Drum shell 11, however, has only a small one axial length and can have a maximum of a traction device record that is formed by the envelope 12 becomes.
  • the drum shell is between one Ring flange 20, 21 of the drum 3 is formed.
  • the traction device is located directly next to the ring flange 20, the one with the smaller end Diameter is assigned as at 22 in FIG. 5 shown performed on the drum.
  • the upper end of the traction means 23 is in front of the drum the implementation 22 on the drum shell 11 with several envelopes as shown at 24 in Fig. 5 wrapped around an inner cylinder 25 of the drum 3.
  • This inner cylinder surrounds the drum axis 26 'around which the drum rotates freely can, as a sleeve.
  • the traction device ends at 23 Sliding contacts 26, 27, which in turn on a stationary contact disk 28 run.
  • the Sliding contacts 26 and 27 and the contact disk 28 lie in a socket 29 for which the cylindrical and the subsequent conical part of the drum 3 are left out at 30.
  • the cylindrical led out of the drum 3 Section of the bushing 29 is labeled 31 in FIG. 3 and provides the work coil for a coil spring (Scroll spring), which is on the coil 31st can roll up and down.
  • a coil spring (Scroll spring)
  • a section enlarged in diameter 33 the coil contains the parts of a freewheel, which can be seen from Fig. 5.
  • a rolling brake can be used for determining the pulling force of the traction device to adjust. If the traction means in the direction the arrow 10 pulled out, so the spring wraps on the work spool 31 on and from the supply spool 32 from. Once envelopes 12 through 17 of the drum is unwound, the drum comes along Reaching the cable entry 22 to a standstill. The one housed in section 33 outside the freewheel The brake then engages and holds the Drum against the spring tension. If the When the lamp is raised, the drum pulls the traction device 10 up through the guide 9, being Envelopes 12 to 17 around the drum shell result of which the drum jacket envelope 17 is the smallest and the drum cover 12 has the largest traction length contain. The winding takes place in the Representation of the figures from right to left.
