Definitions

  • the present invention relates to a one-piece Articulated lock, with a fastening part for fastening the hinged closure near the edge of a housing part, one middle pressure part and a locking bracket, the Fastening part with the pressure part and the pressure part with the Locking brackets are connected by film hinges.
  • the invention particularly relates to an articulated closure for Wet room lights.
  • the construction of damp room lights is e.g. B. is known from EP 0 179 435.
  • a housing part of approximately U-shaped Cross section carries sockets and equipment for a lamp.
  • the housing part also has devices to attach the moisture-proof luminaire to the wall or ceiling or hanging pendulum and cables for power supply introduce.
  • the inside of the housing part is on the Light exit side through a translucent cover trough completed.
  • the housing part and the cover are over their edges connected and by a groove with inserted in it Cord seal on the edge of the housing part and a circumferential Bead sealed at the edge of the cover trough.
  • the detachable Connection between luminaire housing part and cover trough can be designed as a locking connection by means of locking lugs, the either in one piece on the cover trough or on the housing part this are formed.
  • Moisture-proof luminaires from Sylvania are also known, which are equipped with hinged locks, which also 3 parts, but molded in one piece from plastic are.
  • the swivel axes, the movements of the middle Allow pressure part and the locking bracket are with this Construction by so-called film hinges, that is short flexible plastic straps that hold the parts together, replaced.
  • film hinges are as short as possible trained to in the closed state of the Articulated closure the tight fit of the surfaces of the Pressure part on the housing part and on the inner surface not to disturb the locking bracket.
  • the disadvantage is that the film hinges in the closed state have a high bending or Subjected to tensile forces, and pretty rapid wear and tear on these Film hinges occur.
  • the length of the film hinges is preferably selected so that that they form arches when the joint lock is closed, the material of the film hinges is only elastic is deformed.
  • the long film hinges of this joint closure form in closed state of the locking bow with a bow a much larger radius of curvature than the film hinges of the previously known joint locks. Therefore, these are Film hinges only slightly loaded on the bend and the The elastic limit of the material is not exceeded. in the The closed state of the joint lock is convex Side of the film hinges, thanks to the large radius of curvature, only exposed to low tensile forces, so that kinks or Cracks can be avoided.
  • the joint closure shown in Figure 1 is in one piece, made of plastic, e.g. B. polyamide, in the injection molding process manufactured.
  • the Articulated closure on a locking bracket 4 on his free end is bent to a locking hook 14.
  • the film hinge 6 has an extended length of 4 to 8 mm and a thickness of 0.5-0.8 mm, e.g. B. a length of about 5 mm and a thickness of approx. 0.7 mm.
  • the locking bracket opposite end of the film hinge 6 the material goes in a thicker middle pressure part 3 over.
  • the middle one Printing part 3 has a generally elongated shape; it can in particular be rectangular.
  • the joint closure material turn into a film hinge 5 over that like that Film hinge 6 is formed, but from one Side surface 18 of the middle pressure part 3 protrudes while the film hinge 6 from the opposite side surface 19 of the pressure part 3 protrudes.
  • the hinge closure material goes into a fastening part 2 about.
  • the fastening part 2 is designed in such a way that it is in a recess of a housing part, in the Near the edge, can be inserted.
  • Figure 2 shows the location of a moisture-proof lamp with a Cover pan 22 and a housing part 23, where the Articulated closure attached and attached.
  • the edge zone 24 of the housing part 23 is at this point thickened.
  • the fastening part 2 has one to the drawing plane vertical strut 12 and one Leg 13 on.
  • the Fastening part 2 also have a nose 15 which against the middle pressure part 3 is directed so that when the Printing part 3, as shown in Figure 4, against the Turning clockwise around the film hinge 5, the rotary movement is limited by the nose 15. In the opposite direction it is Rotary motion, as described below, also limited.
  • the middle pressure part 3 transmits the pressures from Locking bracket 4 on the fastening part 2, and the two Ends of the pressure part 3 each come with the locking bracket 4 and the fastening part 2 in contact while the Film hinges 5 and 6 curve and approximately semicircular arch form.
  • the middle pressure part advantageously has 3 at its two points of contact with each Fastening part 2 and the locking bracket 4, one each concave 7 and a convex curve 8, each with a convex 9 and a concave conjugate curve 10 the fastening part 2 and the locking bracket 4 at Closure of the articulated closure cooperate so that the rotational movements of the three parts against each other with reduced friction.
  • the Rounding 9 of the fastening part 2 ends in one Stop surface 31 on which the free end 32 next to the curve 7 of the pressure part 3 can come to a stop.
  • the middle pressure part 3 is advantageously not as in the well-known joint locks, as a short intermediate piece formed between the two film hinges 5 and 6, but as an elongated lever arm to the effect of finger presses to improve the locking bracket 4.
  • the end 16 of the Locking bracket 4 may have a projection to Open the joint lock 1, gripped with the fingernail can be.
  • the film hinges 5 and 6 form Circular arcs with an inner radius of approx. 1 mm.
  • the Radius of curvature increases when the Articulated lock and shrinks when closing the Articulated closure, however, remains in the closed Condition always larger than the radius of curvature of the Film hinges of the previously known hinge locks.
  • the joint closure according to the invention can be made of plastic in Injection molding processes are made.
  • the joint closure in the injection mold becomes yours mutual arrangement and the radius of curvature of the Film hinges 5, 6 determined at rest. Through the Curvature at rest, the tensile forces are locked State lowered.
  • the arrangement can be chosen that it facilitates the actuation of the closing process, so that with a single finger actuation the joint lock on the housing part 23 is snapped or engaged and with another one-finger operation can be locked.
