Definitions

  • the present invention relates to a sealed ceiling light comprising a frame half shell, and a transparent screen half shell fitted in sealed manner to the frame half shell using removable lock means.
  • a sealed ceiling light comprising a frame half shell, and a transparent screen half shell fitted in sealed manner to the frame half shell using removable lock means.
  • the screen half shell of known sealed, i.e. watertight, dustproof, ceiling lights is locked in sealed manner to the frame half shell using external lock means, such as lever-operated fasteners, which are locked and released entirely from outside the body of the light.
  • external lock means such as lever-operated fasteners
  • a ceiling light of the aforementioned type wherein the lock means are provided inside the body of the ceiling light, are supported on the inner side of the frame half shell, cooperate with the inner side of the screen half shell, and are connected to control means fitted in sealed manner outwards of the ceiling light, in particular outwards of, and through an opening in, the frame half shell.
  • the control means advantageously present a control member connected operatively to the lock means and projecting outside, and in sealed manner through an opening in, the frame half shell; and a grip member fixable, e.g. force fitted or similar, to the projecting external portion of the control member.
  • a seal may be provided between the grip member and the outer side of the edge of the opening; the grip member being so formed as to overlap the edge of the opening, and being compressed against the seal when assembled.
  • the grip means are recessed inside a recess opening outwards of the frame half shell. Means are also advantageously provided for limiting the operating travel of the lock means.
  • the lock means consist of a lock tooth projecting radially from a control pin supported for rotation inside the frame half shell, so as to rotate from an engaged position beneath a shoulder on the edge of the screen half shell, into a release position and vice versa; and the control pin fits through the opening in the frame half shell, and is secured in rotary manner to the same by a grip knob having a complementary tubular cylindrical extension in which the control pin fits tightly and in non-rotating manner in relation to the grip knob; the tubular cylindrical extension presenting a surface greater in diameter than the opening in the frame half shell; and a sealing ring being provided between said surface of the grip knob and the mating portion of the frame half shell surrounding the opening.
  • Fig.l shows a view in perspective, on the frame half shell side, of a ceiling light in accordance with the present invention and in the open condition; and an exploded view of the lock and control means;
  • Fig.s 2 and 3 show cross sections of a further two embodiments of the ceiling light according to the present invention.
  • the ceiling light according to the present invention presents a frame half shell 1 by which it is fitted, for example, to a ceiling or similar; and a transparent screen half shell 2, one side of which pivots on half shell 1 by means of so-called fallproof hinges 3.
  • Both half shells 1 and 2 are made, for example, of self-extinguishing plastic material.
  • half shell 1 presents supporting elements (indicated as a whole by 4 and shown only schematically by virtue of not forming the object of the present invention) having electric leads for connection to the lamps, in particular, fluorescent tubes 5 and ballasts 6.
  • Half shell 2 is preferably lockable, with edges
  • lock means consisting of a lock tooth 9 projecting radially from a control pin 10 supported in rotary manner about its axis in the upper side of half shell 1.
  • Rotation of control pin 10 provides for rotating lock tooth 9 between a position locking half shell 2 and wherein it engages the underside of an inner peripheral annular shoulder 202 on the edge of half shell 2 (Fig.s 2 and 3), and a release position of half shell 2 (shown by the dotted line and 9' in Fig.l) wherein lock tooth 9 clears half shell 2, which may thus be swung down for opening the ceiling light.
  • Control pin 10 is fitted outwards in watertight and dustproof manner through a hole or opening 201 formed in the upper side of half shell 1; and a tubular cylindrical extension 111 of a grip knob 11 is force fitted on to the portion of control pin 10 projecting outwards of half shell 1, so that control pin 10 is both secured to half shell 1 and rotated by grip knob 11 itself.
  • Opening 201 is sealed by an annular seal 12 inserted and compressed to some extent between the outer surface of the edge of opening 201 and the facing annular mating surface 211 of grip knob 11.
  • Cylindrical extension 111 of grip knob 11 preferably fits through opening 201 and annular seal 12, and presents, on its outer end, an annular shoulder larger in diameter than opening 201 and of substantially the same diameter as annular seal 12.
  • an annular groove 301 is advantageously provided for housing annular seal 12.
  • radially-outer annular shoulder 211 of grip knob 11 presents two peripheral radial limit stop surfaces 311 separated angularly by a distance equal to the angular distance between the engage and release positions of lock tooth 9, and which cooperate with a projection 13 projecting from the outer side of half shell 1.
  • grip knob 11 is recessed beneath the upper side of half shell 1 inside a recess 15 formed in the upper side and open on the nearest lateral edge of half shell 1, so that grip knob 11 is accessible while at the same time protected against inadvertent operation, and in no way interferes with assembly of the ceiling light.
  • limit stop projection 13 of grip knob 11 projects radially towards the center of the opening from a lateral wall of recess 15, and penetrates radially inside the peripheral recess in outer annular shoulder 211 of grip knob 11.
  • grip knob 11 and recess 15 are so sized that a small sector of grip knob 11 projects outwards of recess 15 (Fig.s 2 and 3), and recess 15 flares towards the open side.
