Definitions

  • the invention relates to a lift mechanism for at least one light source, comprising at least one guide device for conducting electrical energy, wherein the at least one guide device can be connected to an electrical source at a first end and to the at least one light source at a second end, a on a ceiling or Mounting plate Housing that can be attached directly or indirectly, in or on which the at least one guide device can be arranged at least in sections, with the second end being at a distance from the housing, and an adjustment mechanism for reproducibly adjusting the distance between the second end of the at least one guide device and the housing via a predetermined one Adjustment range between two end positions by a user.
  • the invention further relates to a method for changing an end position of a distance between a second end of at least one guide device and a housing that can be adjusted over a predetermined adjustment range by means of such a lift mechanism.
  • a lift mechanism according to the preamble of claim 1 is from DD 123 380 known.
  • the disadvantage of this is that the end positions of the adjustment range change when the lift mechanism is installed on ceilings of different heights. This can be associated with an impairment of user comfort, since the lower end position may already be so high with a high ceiling that the user is permanently dazzled. In a small variation range of the ceiling height, this impairment can still be compensated with the help of the adjustment mechanism provided. However, the effectively available setting range is limited.
  • the object of the present invention is to specify a lift mechanism that is improved compared to the prior art and that can be universally adapted to different circumstances without having to the ease of use is impaired and the adjustment range is limited.
  • Another object of the present invention is to specify a method for changing an end position of a distance between a second end of at least one guide device and a housing that can be adjusted over a predetermined adjustment range by means of a lift mechanism improved in this way.

  • This section of the at least one guide device that can be stored in the line store can be used to change the two end positions of the adjustment range and thus adapt the lift mechanism to different ceiling heights. Due to the fact that a section with a variable length can also be stored, the adaptation can take place continuously.
  • the at least one line store is arranged on an outer wall of the housing. In this way, the section of the at least one guide device that can be stored in the at least one line store is easily accessible without the housing of the lift mechanism having to be opened for this purpose.
  • At least one locking device for releasably locking the adjustment mechanism is provided so that the distance between the second end of the at least one guide device and the housing cannot be adjusted by means of the adjustment mechanism.
  • this does not mean that the distance between the second end of the at least one guide device and the housing cannot be changed, but only that the distance cannot be adjusted by means of the adjustment mechanism.
  • the at least one locking device has an actuating element which is arranged at least in certain areas outside of the housing. This in turn increases the ease of use when initially setting the lift mechanism.
  • a particularly convenient solution is characterized in that at least one first locking device is provided, with which the adjustment mechanism can be releasably locked in such a way that one of the two end positions of the adjustment range can be changed, and at least one second locking device is provided, with which the adjustment mechanism can be releasably locked in place is that the other of the two end positions of the adjustment range can be changed.
  • at least one first locking device is provided, with which the adjustment mechanism can be releasably locked in such a way that one of the two end positions of the adjustment range can be changed
  • at least one second locking device is provided, with which the adjustment mechanism can be releasably locked in place is that the other of the two end positions of the adjustment range can be changed.
  • the adjustment mechanism comprises at least one first and one second guide roller, the at least one guide device, the first guide roller being rotatably mounted on the housing and the second guide roller being movably mounted between two maximum positions relative to the first guide roller.

  • Such an acoustic signal output device helps the user, the distance between the second end of the at least one Set the guide device to the housing within the specified adjustment range between the two end positions in a reproducible manner, since it receives acoustic feedback via the signaling device.
  • the lift mechanism makes sense to mount the lift mechanism on a rail system, which can be used to implement a central supply for several lift mechanisms.
  • the connection to the rail system can be made using a rail adapter.
  • the housing it has proven to be advantageous for the housing to have at least two interfaces for at least one rail adapter, via which the first end of the at least one guide device can be connected to the electrical source, with the at least one rail adapter optionally being connected to one of the two interfaces , Preferably by a twist lock, is releasably attachable.
  • the lift mechanism is to be attached to a point in the rail system where two rails are arranged in abutting manner and the connection point is already arranged by a connection adapter which protrudes into both rails, so that the rail adapter no longer has any space there.
  • the lift mechanism can still be arranged over the connection point.
  • the lift mechanism can be used very universally if means are provided on the housing for direct or indirect attachment of the housing to the ceiling or mounting plate.
  • protection is also sought for a method for changing an end position of a distance between a second end of at least one guide device and a housing that can be adjusted over a predetermined adjustment range by means of a lift mechanism according to the invention, wherein in in a first method step a state of the end position to be changed is identified, in a second method step a section of the at least one guide device stored in the at least one separate line store is taken from the at least one line store, provided the length of the section is not equal to zero, in a third method step the length of the section of the at least one guide device is changed, preferably by dragging, and in a fourth method step the section of the at least one guide device that has been changed in length is stored again in the at least one line store if the length of the changed section is not equal to zero.
  • An advantageous embodiment of this method consists in that between the second method step and the third method step the adjustment mechanism is fixed in a further method step by means of at least one locking device, so that the distance between the second end of the at least one guide device and the housing cannot be adjusted by means of the adjustment mechanism, and between the third method step and fourth method step, the adjustment mechanism is released in a further method step by means of the at least one locking device, so that the distance between the second end of the at least one guide device and the housing can be adjusted by means of the adjustment mechanism.

  • the problem with the prior art is then that the end positions 10 and 11 of the adjustment area 9 move, namely upwards when the second ceiling height 72 is greater. If the displacement is smaller than the adjustment range 9, the displacement can be compensated for by adjusting the distance 7 between the second end F of the guide device 3 and the housing 6 within the adjustment range 9. However, this limits the adjustment range 9 that is then effectively available. If the offset is greater than the setting range 9, compensation is not possible. In this case, in the prior art, a user has to live with the fact that the light source is arranged too high or too low, or have the lift mechanism 1 undergo a complex conversion, in the course of which the guide device 3 is changed.
