Definitions

  • ABSTRACT [30] Foreign Application Priority Data Th d f u G 71 27 5462 e lnventlon to a evlce or seeurmg against a wa July 1971 Germany an elongate lighting fitting which 15 provided with pro- [52] U S CI 248/316 R jecting edges extending in its longitudinal direction, [51] In ⁇ .0 "F16"!
  • the invention relates to a device for securing against a wall or ceiling a preferably elongate lighting fitting which is provided with projecting edges extending in the longitudinal direction of the lighting fitting, said device comprising a brace which can be secured to the wall and which comprises at its ends bent hooks for clamping the edges of the lighting fitting.
  • a device for securing against a wall or ceiling a preferably elongate lighting fitting which is provided with projecting edges extending in the longitudinal direction of the lighting fitting, said device comprising a brace which can be secured to the wall and which comprises at its ends bent hooks for clamping the edges of the lighting fitting.
  • a brace which can be secured to the wall and which comprises at its ends bent hooks for clamping the edges of the lighting fitting.
  • the projecting edges can be moved towards each other for clamping between the bent hooks of the brace.
  • This device can be readily used for small lighting fittings.
  • the device according to the invention is characterized in that at least one of the bent hooks is movable in the longitudinal direction of the brace, a clamping member being present with which the bent hook can be tightened in a direction transverse to the longitudinal direction of the brace.
  • the lighting fitting In mounting a lighting fitting to a brace secured to a wall, the lighting fitting is moved between the hooks to the brace until the hooks engage behind the projecting edge.
  • the armature is now suspended from the hooks when it is released and can then be secured by pulling the hook or hooks in the direction of the wall by means of the clamping member.
  • a favourable embodiment of the device according to the invention is characterized in that the brace, at least at its ends, shows a U-shaped profile the side walls of which are provided on their free ends with flanges facing each other, the bent hook comprising a part extending within the profile between the clamping member and the bottom of the profile, the clamping member being furthermore movable by means of a screw bolt in the longitudinal direction of the profile.
  • the clamping member is preferably formed by a cylinder the axis of which extends transverse to the longitudinal direction of the brace and in which an aperture is recessed for passing the screw bolt, said aperture extending in a direction transverse to the longitudinal axis of the cylinder.
  • FIG. shows two devices in a position mounted to a ceiling, and a lighting fitting shown in broken lines which has been secured by means of said devices,
  • FIG. 2 shows the connection of the lighting fitting to the brace
  • FIG. 3 shows an elevation III w III of FIG. 2 of the brace and the end plate secured thereto.
  • the device comprises a brace 1 which has a U- shaped profile (see FIG. 3) the side walls of which are provided with flanges 2 and 3. Two slotted holes 4 are provided in the bottom of the profile.
  • the brace comprises at either end a .I-shaped hook 5 which is manufactured from sheet material and the bent portion 6 of which cooperates with one of the edges 8 and 9 formed on the elongate lighting fitting 7. (shown in broken lines in FIG. 1).
  • the hook 5 comprises a portion 10 which supports against the bottom of the profile with its free end 15.
  • a cylinder 11 which is movable in the longitudinal direction of the brace l by means of a screw bolt 12.
  • the bolt 12 projects through an aperture 13 provided in the hook 5.
  • the end of the brace is partly covered by an end plate 14 which prevents the cylinder 11 from dropping out of the profile.
  • the assembly of the lighting fitting is carried out as follows: the bolt 12 is unscrewed so that same, together with the hook 5 and the cylinder ll, can be manually pulled out until the cylinder 11 bears afainst the end plate 14.
  • the bolt 12 should be unscrewed sufficiently for the hook S to be movable over such a distance that the lighting fitting with its edges 8 and 9 can be guided between the bent ends 6 of the hooks 5.
  • the lighting fitting is then held in the desirable position against the brace, after which the bolt 12, the cylinder 11 and the hook 5 are manually pushed inwards, so that the bent end 6 engages behind the edge 8.
  • the same procedure should be carried out of course for the other end of the brace.
  • the brace is secured to the ceiling with two edge bolts 16 which cooperate with the slotted holes 4. Because the brace is adjustable in its longitudinal direction by means of the slotted holes 4, and be- 7 cause the place of the brace taken in the longitudinal direction of the lighting fitting, can freely be chosen within certain limits, no stringent accuracy requirements need be imposed when placing the wedge bolts in the ceiling. This is advantageous in particular when holes for the wedge bolts have to be drilled in concrete which is usually the case in tunnels.
  • the device is used for securing a lighting fitting against, for example, a vertical wall, it is recommendable to provide the device with a fixed hook to support the lower edge of the lighting fitting and a movable hook as described above to support the upper edge of the lighting fitting.
  • the hooks are preferably formed from a resilient material.
  • a device for securing an elongate lighting fitting against a wall or ceiling which fitting is provided with projecting edges extending in the longitudinal direction of the fitting comprising a brace which is securable to the wall or ceiling and includes bent hooks at its ends to clamp the edge of the lighting fitting, at least one of the bent hooks being moveable in the longitudinal direction of the brace, a clamping member within said brace cooperating with the bent hook to tighten the hook in a direction transverse to the longitudinal direction of the brace, the brace also comprising, at least at its ends, a U-shaped profile including a top wall and two side walls, the side walls being provided on their free ends with flanges facing each other, the bent hook including a portion extending within the profile between the clamping member and the bottom transverse to the longitudinal axis of the cylinder.
