UNITED STATES PATENT OFFICE ADJUSTABLE BED LAMIP WITH EXTENSIBLE SHIELD George J. Rosenthal, Los Angeles, Calif.
Application May 10, 1947, Serial No. 747,280
9 Claims. 1
This invention relates to light sources, and particularly to reading lamps adapted to be attached to the headboard of a bed.
Lamps for this general purpose are well-known, a lamp having adjustable apertures being disclosed in U. S. Patent No. 2,225,727, of December 24, 1940, while an adjustable shade bed lamp is shown in U. S. Patent No. 1,906,626, of May 2, 1933. The present invention, however, is directed to a unit combining two lamps, both of which are under the control of the occupants of a bed, and a light shield or screen which may eliminate the light from one side of a double bed or from one of two twin beds. A light screen for bed use is known, one being shown in U. S. Patent No. 1,979,520, of November 6, 1934.
In the lamp of the present construction. how-. ever, the shield or screen is a part of the lamp unit and is in the form of a foldable fan which may be pulled down when desired, and which, when not in use, may be compactly folded between the two lamps. The unit is arranged to be slideably attached to a mount on the bottom board of a bed so that the unit may be quickly detached from the bed so as not to interfere with the making of the bed. It is also constructed in a manner which permits the ready exchange of lamps and the removal of the light transmitting windows for cleaning.
The principal object of the invention, therefore, is to facilitate the lighting of selected portions of a bed, or the lighting of selected beds.
Another object of the invention is to provide an improved bed reading lamp.
A further object of the invention is to provide an improved bed reading lamp, the direction of illumination of which is controllable by a shield for eliminating illumination from certain portions of a bed.
A still further object of the invention is to provide an easily attachable and detachable reading lamp for a bed which may be used for two persons or for one person, while eliminating the illumination from another occupant of the bed.
Although the novel features which are believed to be characteristic of this invention will be pointed out with particularity in the appended claims, the manner of its organization and the mode of its operation will be better understood by referring to the following specification read in conjunction with the accompanying drawings, forming a part hereof, in whichi Fig. 1 is a perspective view of the invention shown, attached to a heck.

Fig. 6 is a cross-sectional view of the lamp unit taken along the line 6-6 of Fig. 3;
Fig. '7 is a cross-sectional view of the lamp unit taken along the line 1-1 of Fig. 3; and,
Fig. 8 is a perspective view showing a modification of the lamp attached to a single bed.
Referring now to the drawings, in which the same numerals identify like elements, a double bed 5 has a headboard 6 and a bottom cross board 1. Attached to the lower board I is a mounting plate In fastened to the board by a plurality of screws H. The plate H] has attached thereto, by welding or otherwise, a U-shaped channel member M which extends upwardly a predetermined distance, such as to point l5. This channel member is the means for attachingthe lampunit to the bed.
The lamp structure consists of a substantiallyrectangular frame including a back plate I! with. channels l8 and I9, each channel having two-- sides at right angles to one another interconnected .by a 45 section, and a cooperating U-- shaped channel member 20. The channel l8 has. bent-over edges at 22 and 23 and channel l9 has:
bent-over edges at 25 and 26. The elements I1, l8, l9, and 20 may be attached together in any suitable manner, such as by spot welding or by screws. The top of this elongated unit just described has a cover 29 and a bottom member 36,.
the latter not extending completely across to the.-
back plate [1, thus providing a rear opening for the insertion of the U-shaped member 14- mounted on the board 1 into the channel member 20. A stop 32 is provided across the top of the:
I 8 and I9. between the s back and side portions.
be lowered, as shown in Fig. 2.
3 thereof are a pair of elongated lamps 31 and 38 which have conductors leading from a power source through the plug 39 and switches 4i and 42, the switches being connected so that actuation thereof by handles 43 and 44 will energize either lamp 3! or lamp 38 as desired.
Positioned in a square U-shaped channel member 45 between the parallel sides of channel members l8 and I9 is. a fan 46 pivoted at' thebottom on pins 41 and 48 through a front U-shaped member 50 having a cover plate The fan itself may be of stiff cloth or of paper, one edge of which is attachable to the U-shapedv member 45- through a series of fingers as shown at 53' and 54. The other edge of the fan is likewise connected to the front U-shaped member 50'- by aseries of fingers, such as shown at 51 and 58.- A latch element is formed by bending over the upper tip of finger 51 attached to the member 50, this bent-over end sliding under the bent-down edge of. cover: plate 29: The frontplate 5i isextended above the cover 29 and slightly bent-over to forma handle 60- for the fan.-
Thus, to-lower the fan, it is only necessary to grasp the handle 60 and pull it downwardly, the result being as shown inFig. 2'. Thus, if both occupants of the doubleb'ed 5 desire to'read-both lamps 31' and 38 willbe energized and the fan will be folded away as shown in Fig. 1. Should either'occupant desire to read, an'dnot the other,
then one of the desired switches will be operated to energize only: one lamp; and the screen will The screen 46' may be also constructed'a's a separate unit and fittedinto the U-shaped member 45 in any suitable manner, such'as by pins 4'! and 48, or by spring pressed detents.
Referring now to. Fig. 8, the unit's. T0" shownthereinv arevthe same as the unit above described. except that they consistof only a single lamp. H and afan 12'. In-this modification, onev of the lamps has been removed from each of the structures and the shield placed on the side of each single bed adjacent to another single bed. In this manner, two single lamp structuresare em-- ployedinstead of thedouble. lamp unit shown' in Figs. 1 and 2.
