Definitions

  • the present invention relates to a luminaire pendulum, the straight or coiled line of which is inserted into a lampholder for a luminous element, which lampholder has an inner part and a lampholder tube surrounding the inner part and connectable therewith.
  • the invention has for its object to provide a lamp pendant of this type, which is particularly easy to manufacture and assemble with a particularly high level of safety.
  • the frame carrier inner part has an upper fastening section for the cable sheath of the straight line or a pull cable of the coiled line, a middle receiving and guiding section for the line and a lower fastening section for the frame carrier tube.
  • the socket support inner part designed according to the invention ensures a particularly secure reception of the line in the corresponding section, regardless of whether the line is straight or coiled.
  • the pulling cable of the coiled line or the cable sheath of the straight line is fixed to the upper fastening section, the corresponding line or its wires not being affected by this fastening.
  • Fastening section and receiving and guiding section are therefore separate from one another.
  • this fastening section also serves to fix the cable jacket of the coiled line, so that the middle receiving and guiding section can receive the line or the line wires in a strain-relieved manner.
  • the under fastening section for the frame support tube is preferably provided on its outside with a thread onto which the frame support tube can be screwed.
  • corresponding lead-through openings for the line wires are provided, which are guided through the fastening section to the socket.
  • the inventive design of the inner part of the holder thus guarantees, on the one hand, a tensile load on the line wires and, on the other hand, ensures guidance and extensive protection of these wires for the holder itself.
  • the sleeve-shaped inner mount part is slotted in its upper fastening section and receiving and guiding section and has at least one barbed cable sheath grip in the upper fastening section tongue and has in the receiving and guide section and in the socket tube fastening section, a central separator for the cable cores.
  • the barbed cable sheath gripping tongue is pressed against the cable sheath when the frame support tube is screwed on, so that the cable sheath is thereby fixed to the frame support inner part and strain relief for the cable cores is achieved.
  • the middle separator provided prevents the wires from coming into contact with each other.
  • the cable jacket gripping tongue (normally two opposite tongues are usually provided) is then fixed to the cable jacket in the manner described above by subsequently screwing on or sliding on the barrel support tube.
  • the sleeve-shaped inner mount part is preferably particularly slim.
  • the receiving and guiding section of the inner part of the holder is trough-shaped, the pull cable fastening section has a bevel at the lower end for the introduction of the coiled line and the holder tube fastening section has a central separating web for the line wires.
  • the principle according to the invention of separating the fastening and receiving or guiding section is thus implemented.
  • the trough shape of the up The receiving and guiding section offers protection for the line or the line wires and represents a guide for them. Both the pull cable for the helical line and the cable jacket of the coiled line are fixed to the upper fastening section.
  • the cable sheath is preferably fixed in the outer region of the fastening section, and the bevel allows the cable sheath with the line wires to be inserted well into the trough-shaped receiving and guiding section.
  • a corresponding socket upper part is usually inserted into the sleeve-shaped socket holder (socket holder inner part) and glued to it. This takes place via a so-called trumpet nipple, which is inserted into the inner part of the holder. In many cases, a grub screw is also provided to lock the nipple in place.
  • the mounting of the frame carrier on the frame is therefore quite complicated.
  • a further embodiment of the invention provides that the inner part of the frame support is further provided below the frame support tube fastening section with an enlarged upper part compared to this, which is formed in one piece with the inner frame part. That one piece
  • the top part of the socket thus formed expediently has plug-in connection devices for latching with a bottom part of the socket.
  • This embodiment thus has the advantage that the relatively complicated assembly described above is omitted and that instead the inner mount part provided with the upper part of the socket only has to be latched to a corresponding lower part of the socket via a plug connection.
  • the frame upper part is expediently designed as a sleeve section which has a larger diameter than the frame support tube fastening section of the frame support inner part.
  • a conical section is arranged between the widened sleeve section and the mount carrier pipe fastening section.
  • the plug-in connection devices are advantageously formed by at least one nose, which extends from the lower edge of the upper part of the socket with a projection which can be latched with a corresponding recess on the lower part of the socket. It goes without saying that this projection has sliding surfaces which, when the upper part of the frame is slid onto the lower part of the frame, cause the nose to spread and spring back into said recess.
  • the connection can be released again using appropriate aids, for example a conventional screwdriver, by pressing the nose radially outward.
  • the upper part of the frame when mounted on the lower part, forms a roof-shaped cover of the lower part, within which the corresponding line wires are led to the contact points of the lower part.
  • the upper part of the socket has a separator for the cable cores. This separator is particularly insertable and is inserted into corresponding guides on the inside of the wall of the frame during assembly.
  • an anti-twist protection for lamination to be placed on the lampholder is preferably provided on the integrated frame upper part, which expediently comprises at least one hole in which the lamination can be anchored.
  • Two opposing holes are preferably provided. Since these holes are arranged on the widened section of the frame upper part, the particularly large spacing of the holes ensures particularly good rotation lock.
  • the proposed plug connection devices in particular the two opposite lugs, represent a corresponding protection against rotation between the upper part of the frame and the lower part of the frame.
  • a special embodiment of the invention relates to a luminaire pendulum with a coiled line, the helical cable of which has a traction cable which is connected at one end to a traction mechanism arranged in a housing and which is connected at the other end to a lampholder carrier for a luminous element, the lampholder carrier being a Has inner part and associated, the inner part surrounding frame support tube and the frame support inner part has at its helical cable end a traction cable fastening section with a transverse opening for the passage of the traction cable for fastening the same and at its socket end a socket carrier pipe fastening section.
  • the traction rope can be fastened in a particularly simple manner with good, precise positioning on the frame carrier.
  • the fastening opening has a first opening cross-section adapted to the suspension cable cross-section adjacent to the end of the pull coil, a second opening section pointing towards the end of the lamp body for threading the suspension cable with a larger cross-section than the suspension cable cross-section and a third opening section connecting the first and second opening section, the width of which is less than that Suspension cable.
  • the traction cable is provided with an end knot, which represents a thickening, via which the fixation to the frame carrier takes place, even before assembly on the frame carrier.
  • the knotted end of the traction cable is threaded through the second opening section, which is of sufficient size to enable easy threading.
  • the traction rope is then pulled tight, pulling it through the narrowed third opening section and entering the first opening section.
  • the cross section of this section is dimensioned such that the end knot of the pulling rope formed cannot pass through this opening section, so that after the pulling rope is pulled tight, the knot rests on the inner part of the holder and thus the pulling rope is fixed thereon. It is understood that the fixation always takes place in the same place on the inner part.
  • the invention also offers the possibility of producing the end knot only after the pulling rope end has been threaded through the second opening section. Since there is no knotting of the traction cable with a part of the frame support, rather the knot is formed on the traction cable itself, this procedure also offers advantages over the prior art.
  • the fastening opening is expediently designed approximately in the shape of an 8, the first and second opening sections forming the loops in FIG. 9.
  • the two loops are of unequal size; while one loop is used for threading, the other has the task of fixing the pull rope in its final position.
  • the inner part of the frame support has an axial guide channel for the pulling rope, which extends from the end of the pulling helix and merges into the fastening opening.
  • This axial guide channel is formed centrally in the inner part of the holder, so that the traction cable can be deflected after being fixed in the first section of the fastening opening and fitted into the guide channel and thus has a central position in the inner part of the holder or leaves this part in the center of the traction mechanism.
  • it has a side slot.
  • the end of the pull cord is fixed in the first opening section of the fastening opening, it can be inserted into the guide channel by pulling it through the slot, the width of which is slightly less than that of the elastic pull cord (for example made of plastic fibers).
  • the traction cable then extends directly from the second opening section into the guide channel, so that on the one hand a good fixation and on the other hand an exact positioning is achieved in the middle of the inner part of the holder.
  • the fastening opening is expediently designed such that the three opening sections mentioned above are only provided on one side of the inner part, while the opening on the other side has a uniform cross section. This facilitates the threading of the pull rope and its deflection into the guide channel.
  • the remaining opening part preferably has the same cross section as the first opening section.
  • the frame support inner part is designed such that it extends from the frame support tube fastening section, which preferably has a Thread for screwing the frame support tube is provided, a narrower web extends from, at the other end of which the pull cable fastening section is arranged.
  • the section receiving the fastening opening is approximately rectangular, while the section forming the guide channel has the shape of a hollow cylinder.
  • At the side of the rectangular section there is at least one pair of clip-like projections which serve to receive and fix the helix.
  • a pair of projections is expediently arranged on two opposite sides, these pairs being arranged offset with respect to one another in the longitudinal direction in order to enable the helix to be guided around the inner part of the frame carrier.
  • the invention also relates to a pendant lamp with a spiral cable provided with a pull cable and a traction mechanism arranged in a housing for the pull cable, which has an inner part rotatably mounted in the housing, a drum rotatably mounted on the inner part for winding and unwinding the pull cable, a pretensioning device for the drum, a coupling part in the winding direction of the traction rope producing a rotationally fixed connection with the drum, rotatably mounted on the inner part, and a traction brake.
  • a drawbar designed in this way is known.
  • the housing accommodating the traction mechanism is located at the upper end of the traction coil, which contains the electrical lines for the lamp.
  • This pull coil is fixed, for example, on the back of the housing.
  • a device for attaching the housing, for example to a ceiling hook, etc., is arranged on the upper region of the housing. At the bottom of the case there is an opening through which the pull cable leaves the housing in the direction of the lamp.
  • Such a light train pendulum works, for example, such that the pull cable is extended by pulling on the luminous element and is unwound from the drum arranged inside the housing for the traction mechanism.
  • the train brake is in operation, so that the coupling part is held stationary. There is thus a relative movement between the drum and the coupling part when unrolling.
  • the pretensioning device tries to roll up the pull rope again.
  • the coupling part does not move in this direction, there is only a short relative movement between the coupling part and the drum until the non-rotatable connection between the two elements is established by latching suitable parts on the coupling part and the drum. This also stops the movement of the drum in the winding direction, so that the desired train length is maintained.
  • the traction cable is rolled off the drum until the desired length is reached again. The process described above is then repeated.
  • the train brake must be released first. So that the coupling part can rotate again together with the drum in the winding direction, and the tension cable is rolled up again by the pretensioning device. When the desired length is reached, the traction brake is activated again and a brief rest position between the drum and coupling part is achieved by pulling briefly.
  • a lamp pendulum is to be created which has a traction brake which can be particularly firmly engaged and is particularly easy to handle.
  • the inner part has a threaded pin sf protruding from the housing, with which a nut is in screw engagement, which can be pressed against the housing wall by tightening the nut, and a washer is arranged between the housing wall and coupling part, which is fixed by tightening the nut Engagement with the housing wall on the one hand and the coupling part on the other hand is pressed.
  • the train brake is therefore put into or out of action by simply tightening or loosening a nut.
  • the nut is pulled against the housing wall, the threaded pin and thus the inner part is moved relative to the housing wall, the disk provided between the housing wall and the coupling part being pressed against the housing wall and the coupling part rotatably arranged on the inner part being pressed against the disk.
  • the coupling part is fixed, so that the desired locking effect is achieved when the traction cable rolls off the drum.
  • a second disk made of friction material is arranged on the side of the clutch part facing away from the disk, against which the clutch part is pressed for fixing.
  • the second disk rests on a disk-like enlarged part of the inner part, so that in this embodiment the coupling part is pressed on both sides.
  • An essential feature is the design of the nut for applying or releasing the train brake.
  • This nut is expediently designed so that it has a sleeve part with an internal thread for engagement with the threaded pin and a washer part for contacting the housing wall.
  • the washer part When the nut is tightened, the washer part is supported on the outside of the housing wall, so that the threaded pin is pulled in the direction of the housing wall and contact pressure between the washer or washers, the coupling part and the inner part is achieved. If the housing wall is at least somewhat elastic, it is bent slightly inwards so that the contact pressure is increased.
  • the nut expediently has two wings for turning, which are approximately triangular in shape and fastened to the disk part. This allows the nut to be turned particularly conveniently.
  • an annular elevation is arranged on the outside of the housing wall in the outer region of the washer part of the nut, which causes the washer part to deform when tightened and the wings to tilt radially inward.
  • the inner region of the washer part is thus closer to the housing than the outer region when the nut is tightened, so that the washer part and thus the nut are in one tensioned state is maintained.
  • the nut in this embodiment consists of a sufficiently elastic material that enables a corresponding deformation of the washer part. This pretension achieves particularly good compression of the nut and ensures that it cannot be loosened easily. This effect is further reinforced by the radial tilting of the wings.
  • it is preferably provided on its rear side with recesses arranged in a ring.
  • the housing itself expediently consists of two welded plastic shells.
  • the mother is also made of plastic, which is correspondingly elastic.
  • the housing advantageously has a guide rod at the point of exit of the pull cable with an approximately semicircular depression in which the pull cable runs. Even if the pull rope is pulled away from the side of the housing, there is no sharp edge, which could cause gradual wear on the pull rope and eventually cause it to tear.
