Description

CONCEALED BED LIGHTING FIXTURE Filed Nov. 12, 1946 I INVENTOR. W EUGEW J GBEENMQLD ATmPmY Patented June 15, 1948 UNITED STATES PATENT OFFICE-Y Eugene J. Greenwald, Brooklyn, N. Y.
Application November 12, 1946, Serial No. 709,257
1 Claim. (01. 240-4) This invention relates to an improved lighting fixture for beds, and one of its objects is to provide a fixture which can be positioned at the head of a bed and concealed behind the bed head, while illumination is diffused from the front of the bed head by means of a pendant U-shaped diffusing plate.
Another object of the invention is to provide means for varying the amount of light which is transmitted to the light diffusing means from the electrical lamp, which is itself concealed behind the head of the bed, and therefore protected from tampering by a child.
With the. above and other objects in view the invention comprises certain new and useful constructions, combinations and arrangements of parts, clearly described in the following specification, and fully illustrated in the drawings, in which:
Fig. 1 is a perspective view.
Fig. 2 is a horizontal sectional view, taken on line 2--2 of Fig. 1, looking in the direction of the arrows, the difillsing plate being omitted.
Fig. 3 is a vertical sectional view, taken on line 3-3 of Fig. 1, looking in the direction of the arrows.
Fig. 4 is a fragmentary and similar view, showing the electrical lamp turned to diminish the illumination transmitted to the light diffuser.
Referring to the accompanying drawings, which illustrate the invention, 5 designates a conventional electrical socket of the flexible chain pull type, and 6 a metal shell or housing, which is shown to be substantially tubular or cylindrical in form, and provided with a longitudinal slot 1, and parallel longitudinal flanges 8 and 9, extending radially from the sides of the said slot.
On the inner end of the housing shell 6 an end cap H] is mounted, which is provided with an inner flange I I which is formed with screw threads to engage the screw threads of the socket neck I2. The other end of the housing shell is provided with an end cap l3. The end cap l isformed with openings 10a for ventilation. The pull chain 511 of the socket is arranged so that it will hang in accessible position outwardly of the end cap In the longitudinal slot 1 the rear and inner leg I4 of the U-shaped difi'using plate or means I5, is disposed. The inner leg I4 is disposed in an approximate vertical plane, and the outer leg I6 is also disposed in an approximate vertical plane, with the connecting portion II disposed in a low or moderate arc, so as to provide a rest to engage the upper horizontal edge of the head member of the bed, as indicated in dotted lines in Fig. 3. The inner vertical leg [4 is secured to the parallel side flanges 8 and 9 by means of the metal screws I8, and the nuts 18a, and these screws extend through both flanges and the intervening material of the inner vertical leg M.
The entire U-shaped light diffuser I5 is made of transparent plastic material capable of bending the rays emitted by the electrical lamp l9, which is coupled to the socket neck I2 in the usual manner. The light is diffused through the body of the diffusing plate forwardly and downwardly by the front or outer leg IS, in a glareless emission.
The electrical lamp bulb I9 is provided with a silvering coating |9a on one longitudinal side thereof, leaving an uncoated side l9b. As shown the silvering coating covers about one half of the area of the bulb, which is of the cylindrical type. By rotating the socket 5 the position of the lamp bulb l9 may be varied in the housing shell 5.
In the position shown in Fig. 3 the uncoated side IE1) or the lamp bulb will be disposed in full opposition to the horizontal end face Ila of the inner leg 14, and the maximum amount of light will be transmitted to the diiiuser l5. By turning the lamp socket 5 the silvering coating l9a may be disposed in opposition to the end face Ma of the inner leg, and only light reflected by the inner con-cave wall of the housing shell 6 will be transmitted to the diffuser 15.
The cross connecting portion or rest I! engages the upper end of the head member of the bed, so that the entire light fixture, including the socket 5, the shell 5, and the coupled supply or service cord, is concealed by the head member of the bed, and thereby rendered inaccessible to any child sleeping or using the bed or crib on which the improved lighting unit is placed.
The lighting unit offers many advantages for illuminating a childs crib, since it can be mounted in place without any clamps or securing means, easily shifted horizontally 0n the end of the crib, and the amount of illumination varied at will.
It is understood that various changes may be made in the details of construction, their combination and arrangement of parts, clearly described in the foregoing specification, and fully illustrated in the drawings, and defined in the claim.
Having described the invention, I claim as new:
A lighting fixture adapted to be hung over a bed in a reverse fashion comprising a transversely elongated U-shaped member formed, of li'ht transmitting material, and having a long 1% adapted to extend over the front of the bed a d a short leg adapted to extend downwardly over the back of the bed, an elongated shell connected to the short leg of the member and supported therefrom, said shell having a threaded flange at one end thereof, a threaded lamp socket supported by said 'flange, atubular,1amp-?bu1 b connected to "the socket and extending longitudinally through the shell, the legs of the U- shaped member being connected together by a horizontal portion adapted to-rest-on P1111619!) edge of bed; a reflector covering substantially one-half of the surface of the tubularalampxbullo and mounted so as to reflect .light toward, the short leg of the U-shaped member; said soket and lamp bulb being rotatively adjustable win 4 relation to the shell so as to vary the amount of light being transmitted through the U-shaped member.
