13 Claims. (Cl. 240-81) This invention is concerned with a lamp, particularly with a floor lamp designed for hospital or other bedside use.

Several characteristics are necessary or desirable in lamps designed for bedside use. The source of illumination must be capable of being positioned over a bed and yet the lamp must be firmly balanced and substantially incapable of being tipped. A general broad distribution of illumination is necessary for reading in bed and for general diagnosis, but a relatively small spot of light is necessary for many diagnostic and observational purposes. l'he light must be capable of being aimed and must remain firmly in any position set, preferably without the need of any manipulations to fix the light in the position aimed. Hospital and other bedside lamps frequently are located in otherwise darkened rooms, and it is desirable to be able to find the lamp readily and to turn the lamp on without danger of bumping against the lamp or other objects to disturb a sleeping person.

An object of this invention is to provide an improved bedside floor lamp of improved stability.

Another object of this invention is to provide a bedside lamp having both broad general ilumination and a relatively small spotlight.

A further object of this invention is to provide a lamp of the foregoing character which is continuously adjustable in substantially any direction.

A still further object of this invention is to provide improved structure permitting ready adjustability of a lamp and firmly holding the same in adjusted position.

Another object of this invention is to provide a hospital or bedside lamp having a separately controlled night light or locator light.

A still further object of this invention is to provide a hospital or bedside lamp of improved appearance and functional construction.

Other and further objects and advantages of the present invention will be apparent from the following description when taken in connection with the accompanying drawings wherein:

Fig. 1 is a side view of a lamp constructed in accordance with the principles of my invention;

i aired States Patent C i 2,745,949 Patented May 15, 1956 Fig. 11 is a cross-sectional view through the lamp standard and base;

Fig. 12 is a front view of the lamp standard and assembled switch and outlet panel;

Fig. 13 is a cross-sectional view along the line 13-13 of Fig. 11; and

Fig. 14 is a cross-sectional view through the base along the line l4-14 of Fig. 11.

Referring now in greater detail to the figures, and first to Fig. l for a general view of my lamp, the lamp will be seen to comprise a base 20, an elongated, tubular lamp standard 22 upstanding from one edge thereof, and a lamp shade 24 mounted at the upper end of the standard by adjustable mechanism including a housing 26. The shade 24 is substantially aligned with and positioned above the base 20. Since the shade 24 projects laterally from the standard 22, the shade readily may be positioned above a bed. The alignment of the shade above the base precludes any tendency of the lamp-to tip toward the shade.

The shade, as may be seen in Figs. 1-5, comprises a dished out sheet metal section having a rolled over peripheral bead 28 and a central aperture 38 in which is mounted, by means of a crimped over flange 32, an outwardly flared circular spotlight member 3 having a peripheral bead 36. A socket 38 is mounted within the shade 24 in a manner shortly to be described and supports a light bulb 4G in alignment with the aperture 30 and spot 34.

A bulb shield 42 shown in Figs. 2-4 and best seen in the perspective view of Fig. 8 is provided with a split cylindrical portion 44 encircling the socket 38 and su porting a substantially hemispherical portion 46 about the bulb. The end of the split cylindrical sleeve portion 44 is provided with a substantially right-angularly disposed fiange 48 (see also Fig. 7) provided with a pair of screw holes for receiving screws 50 which also pass through the shade 24 (see Fig. 6) and are threaded into the housing 26. The shade 24 further is secured by screws 52 passing through the shade and threaded into the housing above the socket 38 and bulb shield 42. The spherical portion 46 of the bulb shield partially surrounds the bulb 40 and is aligned with the opening 36 and spotlight member 34 to cast a spot of light through the latter and also to reflect light onto the inside of the shade so that indirect light may be reflected outwardly from the shade. The inside of the bulb shield and the inside or" the shade both are coated with a reflective substance such, for example, as white enamel although it will be understood that any other suitable or desirable coating may be used.

The shade in one position of adjustment has its concave side directed downwardly as shown in Figs. 1, 2, and 6 and in solid lines in Fig. 4 to provide relatively broad difiused or indirect lighting for reading and the like. The shade is rotatable about the axis of the bulb and bulb shield as indicated in dashed lines in Fig. 4 and may be completely inverted as shown in Fig. 3 so that a spot of light emanating from the bulb and passing through the member 34 may be directed downwardly onto a patient or the like.

The structure for adjusting the shade 24 is shown in Fig. 6 and includes a substantially L-shaped casting 54 having a hollow portion 56 over the top of the tubular standard 22 and fixed thereon by means such as a set screw 58. The casting 54 further includes a transverse tube 69 joining the remainder of the casting at a shoulder 62 and fitting through a hollow sleeve-like portion 64 of the housing 26. Both the sleeve-like portion 64 and the tube 60 project through an opening 66 in the shade 24 and a cylindrical socket holder 68 is secured on the end of the tube 61) by means such as a set screw 70 72 on the side of the tube 69.

A centering ring 74 of substantially trapezoidal cross section encircles the tube 66 and is forced. resiliently against a beveled inner edge of the housing sleeve 64 by a coil spring 76 carried within the socket holder 68 and abutting an internal shoulder 78 therein. The coil spring holds the centering ring 74 tightly against the tube 64 and holds the housing tightly against the shoulder 62 of the casting 54 frictionally to lock the housing, and consequently the shade 24, in place. A manual rotative force applied to the shade is sufficient to overcome the frictional locking force so that the shade may be continuously adjusted to any desired position, the housing and shade then being frictionally locked in the new position as previously described.

The socket holder 68, which conveniently is formed of metal, is provided at its outer end with 'a pair of diametrically spaced cylindrical projections 89' (Figs. 6 and 7) which are bored and tapped for receipt of a pair of screws as will be apparent shortly.

The socket 33 previously mentioned is formed of in sulating material such as porcelain and is provided with a pair of recesses into which the projections 80 fit. Screws S2 fit into countersunk bores in the insulating socket 38 and are threaded into the tapped apertures in the projections 39 to hold the socket firmly in place. The usual metallic, screw threaded contact member 84 is secured in the socket 3% by any suitable or conventional means (not shown) and an open bottom portion 86 on the screw threaded contact 84 is closed by an insulating member 83 carrying a contact button 90, as is well known in the art. Wires 92 and 94 lead from the screw threaded contact 84 and contact button 9% through the tube 69 and down through the tubular lamp standard 22.

Reference next should be had to Figs. 11 and 14 for details of construction of the base 2%. The base 2% comprises a casting 96 of a relatively heavy metal such as iron for providing stability to the lamp. The casting has a plurality of tapped apertures for receiving screws holding rubber or similar feet 100 on the bottom of the base. The casting )6 is substantially circular and is provided with a convex upper surface over which is fitted a sheet metal stamping 192. This provides a smooth finished top to the base without the necessity of machining the casting.

An elongated, streamlined casting or support member The support member is provided with cylindrical vcrtical bosses forming a tube-like portion 11% receiving the lower end of the lamp standard 22. A lip 112 is bent upwardly and inwardly to support the weight of the standard 2'2 and of the parts carried thereby. The lamp standard 22 is held against upward movement by a press fit in the tubular portion 119 and additionally may be secured by any suitable or desirable means including welding, soldering, or screw threads, or by a set screw or screws.

The sides of the elongated support member 184 are apertured at 114 forwardly of the shoulders 186 and a light source is placed within the member 194 to shine.

outwardly through these apertures to act as a night light or a locator light. The top of the member 104 is provided with an elongated aperture 116 which isclosed by a cover 118. The cover 113 is provided with a lug 120 having a shoulder 122 fitting under the member 184 at one end of the aperture 116. The other end of the cover 118 is held in place by a screw 124 extending through the cover and threaded into the member 134. A screw 126 is threaded through a socket member 128 and into the lug 120 to mount the socket member within the elongated support member 104. The front end of the socket member 128 is located by an apertured flange 130 extending downwardly from the cover 113. A small bulb 132 is threaded into the socket member 128 and is positioned adjacent the apertures 114 to cast light outwardly therethrough.

An electric switch and outlet panel 134 is located on the front of the lamp standard 22 at a comfortable height, preferably somewhat greater than half way from bottom to top. The panel 134 (Figs. 1, 9, 11, 12 and 13) is elongated and is curved at the ends to provide a neat appearance and to avoid the possibility of corners on which clothing or the like could catch. The panel 134 is provided with longitudinal folded over edges 135 which are curved transversely in order to be complementary to the outer surface of the tubular lamp standard 2 and is held against the front surface of the lamp standard by a pair of screws 136 passing through the panel and threaded into the lamp standard. The standard is apertured at 13$.behind the panel as shown in Figs. 11, 12, and 13 in order to accommodate a pair of switches and an outlet socket as will be apparent shortly. V

The center of the panel 134 is provided with'a rectangular opening 140 (see particularly Fig. 9) for receipt of an outlet or plug receptacle 142 (Figs. 11-13). The receptacle is held against outward movement by a bracket 14-4 secured to the back of the receptacle by a screw 146 and having a pair of diverging legs 148 impinging against the back or inside of the panel 134. The receptacle or outlet 142 is held against inward movement by an integral flange 15?; on the outlet bearing against the outer surface of the panel 134.

The panel 134 further is provided with a pair of'circular apertures 152 and 154 (Fig. 9) spaced between the screw holes and the rectangular aperture 140 for receipt of a pair of conventional snap switches 156 and 158 (Figs. 11 and 12) for controlling the operation of the main light bulb 40 and the night light bulb 132. The switches are held in place by nuts 160 and 162 clamping against the front face of the panel and threaded on to shafts extending from the fronts of the switches. Switch actuating levers 164 and 166 extends from the fronts of the switches, and suitable ON-OFF indicia are provided on the front of the panel as shown in Fig. 12.

A wiring diagram for my lamp is shown in Fig. 10. The Wire 92 from the bulb'40 will be seen to lead to the switch 156 (see also Figs. 6 and 11). A wire 168 leads from the switch 156 down through the tubular lamp standard 22 and out through the rear end of the support member 104 into a two-wire cable 170 provided with an 7 integral grommet member 172 snapped into an aperture in the support member 104. The wire 94 leads from the bulb 40 to the two-Wire cable 170.

The outlet or plug receptacle 142 is connected between the wires 94 and 168 by lead wires 174 and 176 so that power at all times is supplied to the outlet. A wire 178 leads from the wire 168 to the switch 158, and a wire 180 leads from the switch 158 to the bulb 132, the circuit being completed by a wire 182 leading to the wire 94. The switches 156 and 158 allow the main light or bulb 40 and locator or night light or bulb 132 to be energized selectively.

The disposition of the lamp shade and base both to the same side of the lamp standard allows the lamp shade to be positioned directly over a bed with no danger of tipping. The cast metal portion of the base further adds to the stability. The unique design of the lamp shade and bulb shield aflords a source of broad general illumination or a concentrated spot of light, while the improved mounting structure for the shade allows the direction of the shade, and hence of the light, to be continuously adjusted in any direction. After adjustment the mounting structure frictionally holds the shade in adjusted position. The lamp has a pleasing appearance and the functional construction of the lamp avoids useless trimming or other parts that might catch on clothing or the like. The night light or locator light allows the lamp to be located readily in an otherwise darkened room and provides a comforting source of low level illumination for restless sleepers.

Although a particular example of my invention has been shown and described, it will be understood that this is by way of example only and does not constitute a limitation on the invention which includes all that which falls fairly within the spirit and scope of the appended claims.
