Definitions

  • the invention relates to a connecting device according to the preamble of claim 1.
  • a luminaire in particular a luminaire for accommodating linear fluorescent lamps, has a luminaire housing and a transparent luminaire trough or cover trough that is rotatably connected to the luminaire housing at least on one of the longitudinal edges so that the trough can be folded down for opening and replacing the fluorescent lamps.
  • Such articulated connections are formed, for example, by pins which are integrally formed on the trough and which can be inserted into corresponding eyelets on the housing.
  • a connecting device of the type mentioned is known from US-A 4,390,114.
  • a glass pane is fastened to a lamp housing which is square in cross section by means of a frame, with eyelets and pins being formed on the frame and plugged into one another so that an articulated connection of the frame with the glass pane and the lamp housing is achieved.
  • a radially projecting hook is provided on one of the lugs of the luminaire housing, which hooks behind the eyelet in the assembled state and serves as a stop against longitudinal displacement.
  • the object of the invention is to provide a connecting device of the type mentioned, in which the assembly is considerably simplified, without being longitudinally displaceable in the folded state. This displacement of the cover is also to be prevented if the cover is folded up vertically, that is to say it is brought into the position in which the plane spanned by the free edge of the cover is perpendicular to the plane spanned by the free edge of the housing.
  • the assignment according to the invention of the first flattening and the groove to the transverse pin in the eyelet means that the pin or the pins can be inserted into the eyelet in a position folded down at an angle between the tub and the lamp housing. The pin is then pushed into the eyelet until the assembly position is reached and until the groove lies in the area of the cross pin. The tub can then either be closed or moved to the fully opened position. Characterized in that the cross pin engages in the groove, a security against longitudinal displacement of the tub relative to the housing is achieved.
  • the first flattening is arranged in such a way that when the trough is fully opened or folded down, the flattening rests directly on the corresponding inner surface of the eyelet, and in a corresponding manner the groove is arranged such that the cross pin engages in this position.
  • the cross pin can either be formed by a metal pin which is inserted into a corresponding opening in the eyelet or by the cross pin being integrally formed on the eyelet.
  • a further advantageous embodiment of the invention can be gathered from the characterizing feature of claim 5.
  • the tub is placed at an angle to the housing for the purpose of mounting, the pins being aligned with the eyelets.
  • the angle is determined by the angle formed by the flattening with the plane spanned by the free edge of the tub. In this angular position of the trough, the flats run parallel to the cross pins and thus each pin can be pushed into the clear cross-section of the eyelet, which is narrowed by the cross pin, until the cross-sectional constriction on the pin is in the area of the cross pin.
  • the trough can be pivoted into the closed position without being hindered by the shape of the pin is then due to the suitable arrangement of the narrowing of the cross section of the pin.
  • the flattened cross-sectional shape fits through the eyelet so that the closing is not hindered; if now the Trough is folded up into the vertical position, then the cross pin engages in the area of reduced cross-section on the pin, which is practically formed as an edge-like groove, and the pin becomes through the axial side walls of this area with reduced cross-section on the pin, which cover the cross pin in the eyelet or the pins and thus the tub are held on the housing so that the tub can no longer be moved in its longitudinal direction.
  • FIG. 1 only part of the lamp housing 10, hereinafter referred to as housing 10, and part of the transparent cover trough 11, referred to below as trough 11, are shown in FIG. 1. shown.
  • a plurality of eyelets 14 are attached to the inner surface of the side wall 12 in the region of the edge flange 13 of the housing; only one eyelet is visible in FIG. 1.
  • this eyelet 14 has an opening 15 running in the direction of the longitudinal edge of the housing 13 and a tab 16 with which the eyelet is fastened to the housing or to the side wall 12.
  • Attachments 18 are fastened to the inner surface of the side wall 17 of the tub 11; only one attachment 18 is also shown here.
  • Pins 19 are formed on these, which extend in the direction of the longitudinal edge 11a of the tub 11. The pins 19 are inserted into the interior or into the opening 15 of the eyelets 14.
  • FIG. 3 shows the eyelet 14, which is formed by a hollow profile with a side wall 20 fastened to the inner surface and a side wall 21 running perpendicular thereto, which is supplemented by a curved wall 22 to form a closed ring.
  • the clear distance between the side wall 20 and the cross pin 23 is denoted by d3.
  • the pin 19 has an asymmetrical cross section with a first flattening 26 which, in the assembled closed state, lies from the tub 11 to the housing 10 against the side wall 20.
  • a further flattening 25 is provided in the region of the free end of the pin, which is dimensioned such that the vertical distance from the flattening to the diametrically opposite end or the diametrically opposite surface line has the value d2. If the tub 11 is held at an angle corresponding to the angle alpha or alpha 1 to the housing, then the pin with the flat 25 can be inserted through the clear cross section 24 between the side wall 20 and the cross pin 23.
  • the distance from the diametrically opposite surface line also has the amount d2.
  • the cross pin When the pin is pushed into the eyelet, the cross pin then reaches the region 27 of the narrowed cross section, the groove depth or the groove base 28 of this region with a narrowed cross section extending perpendicular to the flattened area 26. Since the distance d2 is slightly smaller than d3, in this position of the pin based on the transverse pin 23 or the tub 11 based on the housing 10, the tub can be closed, so that the free edge of the tub 11 against the free edge of the housing 10 comes to mind.
  • the cross-sectional shape in the area of the cross-sectional constriction 27 permits this 90 ° rotation.
  • the cross section of the pin in the area of the groove 27 has an envelope radius d2, which is why the pin can be rotated into the eyelet in the area of the cross pin.
  • the outer diameter of the enveloping circle, which surrounds the pin, is greater than the distance d3, so that when the cross pin is in this area 27, the tub 11 can no longer be moved relative to the housing 13 when the tub by 90 ° is folded up, i.e. is open.
  • the flat 25 covers the groove 27.
  • FIG. 7 shows a luminaire in the opened position with a luminaire housing 70 and a luminaire trough 71.
  • the luminaire housing 70 has a circumferential edge 72 which is integrally formed on a recess 73 running perpendicularly thereto; the circumferential edge 72 runs parallel to the side walls 74 in the direction of the open side of the lamp housing 70.
  • On the inner surface of the edge 72 there are several eyelets 75 which are curved approximately in a quarter circle, of which only one can be seen in FIG.
  • each eyelet has an L-shaped structure with a leg 76 running parallel to the edge 72 and a further leg 77 running perpendicular to it.
  • a parallel to the leg 76 is a, reducing the clear cross section 78
  • Cross pin 79 is provided, which corresponds to the cross pin 23 of the embodiment according to Figures 1 to 6. 7 shows the hole 80 in the eyelet through which the cross pin is inserted.
  • the trough 71 has a U-shaped trough rim 81 projecting in the opening direction, in the interior of which a seal 82 is inserted which projects beyond the free edge of the trough rim.
  • the U-shaped tub edge 81 is on a parallel to the bottom surfaces 83 of the tub 71 to the inside molded in the area of the longitudinal edges of the inner flange 84, which inner flange forms an acute angle with the side wall 85 of the trough, which deviates slightly from 90 °.
  • a plurality of supports 86 (only one of which can be seen) are provided, which run perpendicular to the course of the longitudinal edge of the tub 71 and parallel to the plane spanned by the U-shaped edge 81;
  • a pin 87 is formed perpendicularly thereto, that is to say in the direction of the longitudinal edge of the tub, which has a flattened area 88 on its side facing the tub edge and has a groove 89 on the side lying parallel to the tub rim plane.
  • the trough 71 is to be placed in a position on the lamp housing which is oriented at an angle to the lamp housing which is less than 90 °. so that the pin 87 fits through the clear cross section 78.
  • the pin is pushed so far into the eyelet that the groove, which is only shown in broken lines in Figure 9. located in the area of the transverse pin 79, then, as can be seen from FIG. the tub can be pivoted completely into the folded-down position, which is indicated in FIG. 7, in which the transverse pin 79 engages in the groove 89.
  • a stop 75a is provided in the area of the eyelet 75, against which the free end of the pin 87 comes to rest during assembly.
