Definitions

  • This invention relates to a high-intensity lamp of the type utilizing a physically small, low-voltage, incandescent lamp bulb together with a transformer for connecting the lamp bulb to a commercial source of electrical energy.
  • Lamps of this general character have become increasingly popular for use as student desk lamps primarily on account of compactness of design permitted by the small size lamp bulb.
  • a small reflector can be used in conjunction with such lamp bulb to achieve a concentrated light beam and thus the efficient illumination of a book or other small object.
  • the primary object of this invention is to provide a high-intensity lamp of this character which requires very little supporting area on a desk or other surface.
  • the lamp comprises a pair of generally cylindrical parts, one a base housing the transformer, and the other, a reflector housing movable from a juxtaposed closed position with respect to the base to a wide variety of operative positions above and laterally beyond the base.
  • Another object of this invention is to provide a compact lamp of this character capable of use as a night light.
  • the reflector housing is provided with a translucent rim that forms the only aperture for efliuent light when the cylindrical parts are closed.
  • Switching means connects the lamp bulb to a low-voltage tap of the transformer.
  • Another object of this invention is to provide an improved switching assembly for a high-intensity lamp of this character the actuator of which is inconspicuous, yet readily accessible for manipulation, and even when the lamp parts are closed.
  • a radio-type selector switch that is quite adequate for low-voltage switching, and accommodated in the top of the base part, the switch having the conventional shaft for cooperation with a knob actuator.
  • a disc is provided that not only provides the aperture for coupling to the switch shaft, but which also neatly closes the top of the base part.
  • the rim of the discrclosure is accesible for manipulation substantially equally from any lateral approach.
  • Another object of this invention is to provide a lamp of this character capable of use as a flood light.
  • the cylindrical reflector housing is so mounted that it may be inverted while yet in juxtaposed relationship with the base part. Accordingly, the reflector directs a light beam upwardly for reflection from the ceiling, whereby broad illumination is obtained.
  • Another object of this invention is to provide a lamp of this character that is capable of use as a search light
  • the lamp assembled with the reflector housing inverted, can :be grasped conveniently by the base, and the beam can be directed as desired by the user.
  • Still another object of this invention is to provide a lamp of this character that can be used as a wall lamp to provide spot illumination for any desired purpose, as
  • a wall-hung art object for example a wall-hung art object or as: a bed reading lamp.
  • Another object of this invention is to provide a stabilizing foot and unique case elements for retractably receiving it, and swingably mounting it to project from either side, the foot also serving conveniently as a means detachably cooperable with a wall bracket for thus mounting the lamp.
  • Another object of this invention is to provide improved suction cup for stabilizing the base, and which nevertheless allows the lamp to be attached to a wall.
  • the suction cup is formed as an annulus, whereby a suspension device may cooperate with an aperture located in the ring.

HIGH-INTENSITY LAMP Filed Jan. 10, 1966 3 Sheets-Sheet l m [NVENZ'OP W10 M/NO/FC/ flmq/e/ United States Patent 3,315,073 HIGH-INTENSITY LAMP Minoru Araki, Tokyo, Japan, assignor to Z & T Importing Co., Inc., Los Angeles, Calif., a corporation of California .Filed Jan. 10, 1966, Ser. No. 537,247 Claims priority, application Japan, Apr. 19, 1965, 40/030,576 26 Claims. (Cl. 240-36) This is a continuation-impart of application Ser. No. 486,891, filed Sept. 13, 1965, now abandoned.
This invention relates to a high-intensity lamp of the type utilizing a physically small, low-voltage, incandescent lamp bulb together with a transformer for connecting the lamp bulb to a commercial source of electrical energy.
Lamps of this general character have become increasingly popular for use as student desk lamps primarily on account of compactness of design permitted by the small size lamp bulb. Thus, a small reflector can be used in conjunction with such lamp bulb to achieve a concentrated light beam and thus the efficient illumination of a book or other small object.
The primary object of this invention is to provide a high-intensity lamp of this character which requires very little supporting area on a desk or other surface. For this purpose, the lamp comprises a pair of generally cylindrical parts, one a base housing the transformer, and the other, a reflector housing movable from a juxtaposed closed position with respect to the base to a wide variety of operative positions above and laterally beyond the base.
Another object of this invention is to provide a compact lamp of this character capable of use as a night light. For this purpose, the reflector housing is provided with a translucent rim that forms the only aperture for efliuent light when the cylindrical parts are closed. Switching means connects the lamp bulb to a low-voltage tap of the transformer.
Another object of this invention is to provide an improved switching assembly for a high-intensity lamp of this character the actuator of which is inconspicuous, yet readily accessible for manipulation, and even when the lamp parts are closed. For this purpose, use is made of a radio-type selector switch that is quite adequate for low-voltage switching, and accommodated in the top of the base part, the switch having the conventional shaft for cooperation with a knob actuator. However, in place of the conventional knob actuator, a disc is provided that not only provides the aperture for coupling to the switch shaft, but which also neatly closes the top of the base part. The rim of the discrclosure is accesible for manipulation substantially equally from any lateral approach.
Another object of this invention is to provide a lamp of this character capable of use as a flood light. For this purpose, the cylindrical reflector housing is so mounted that it may be inverted while yet in juxtaposed relationship with the base part. Accordingly, the reflector directs a light beam upwardly for reflection from the ceiling, whereby broad illumination is obtained.
Another object of this invention is to provide a lamp of this character that is capable of use as a search light For this purpose, the lamp, assembled with the reflector housing inverted, can :be grasped conveniently by the base, and the beam can be directed as desired by the user.
Still another object of this invention is to provide a lamp of this character that can be used as a wall lamp to provide spot illumination for any desired purpose, as
for example a wall-hung art object or as: a bed reading lamp.
Another object of this invention is to provide a stabilizing foot and unique case elements for retractably receiving it, and swingably mounting it to project from either side, the foot also serving conveniently as a means detachably cooperable with a wall bracket for thus mounting the lamp.
Another object of this invention is to provide improved suction cup for stabilizing the base, and which nevertheless allows the lamp to be attached to a wall. For this purpose, the suction cup is formed as an annulus, whereby a suspension device may cooperate with an aperture located in the ring.
This invention possesses many other advantages, and has other objects which may be made more clearly apparent from a consideration of one embodiment of the invention. For this purpose, there are shown a few forms in the drawings accompanying and (forming a part of the present specification, and which drawings are true scale. These forms will now be described in detail, illustrating the general principles of the invention; but it is to be understood that this detailed description is not to be taken in a limiting sense, since the scope of this inven* tion is best defined by the appended claims.

FIG. 16 is a fragmentary sectional view taken along a plane corresponding to line 16-16 of FIG. 14.
The lamp structure shown in FIG. 1 comprises a base housing part 10 and a reflector housing 12, both substantially of cylindrical form. The base housing 10, as shown in FIG. 4, comprises three parts made of molded plastic: an open-ended tubular part 14, a lower end closure 16, and a knob 18 that closes the upper end of the tubular part 14.
The base housing part 10 and the reflector housing 12 are connected together by a two-part foldable arm structure 20. The arms 22 and 24 are made, in this instance, of hollow rectangular stock material, such as stainless steel. The arm 24 has a length corresponding substantially to the height of the housing 10, and the arm 22 is slightly longer.
A first hinge assembly 26 has two channel-shaped leaves 28 and 30 that are press-fitted in the ends of the tubular arms 22 and 24.
A second hinge assembly 32 has one channel-shaped leaf 34 press-fitted in the opposite end of the longer arm 22, and another leaf in the form of a U-shaped bracket 36. The bracket 36 carries a hollow pin 38 that extends through an aperture 40 in the reflector housing 12 for pivotally mounting the reflector housing 12 for movement about the axis of the pin. The aperture 40 is precisely located midway of the height of the housing 12 which allows the housing 12 to be inverted relative to the base housing 10 for purposes hereinafter to be described.
A third hinge 42 has one channel-shaped lea-f 44 pressfitted in the opposite end of the shorter arm 24. The other leaf of the hinge 42 is in the form of a bracket 46 that serves as a means for mounting the arms 24, 22 and the reflector housing 12 on the base housing 10. The bracket 46 extends into housing 10 through an aperture 48 located laterally at the top of the housing 10. (See also FIG. 3.) The bracket 46 extends along the inside of a bottom wall 50 (FIG. 4) of a vertically extending channel-shaped recess 52 formed along the side of the housing 10. The channel 52 forms a space for reception of the shorter arm 24 when the arm is folded inwardly about the hinge 42. The depth of the channel decreases from a maximum at the aperture 48. Accordingly, the hinge 26 at the lower end of the arm lies just laterally beyond the lower portion of the base 10 when the arm 24 is in the channel.
The longer arm 22, as shown in FIG. 2, may be folded against the case 10 to double back along the arm 24. In this position, the reflector housing is in juxtaposed relationship to the base 10. The arm 24 can be folded upwardly for approximately 180 and substantially to the position shown in FIG. 1. The arm 22 likewise can be moved substantially through an arc of approximately 270 from its folded relationship with respect to the arm 24. The reflector housing 12 can furthermore be tilted about its hinge 32 as well as swivelled about its mounting pin 38. Accordingly, a wide variety of orientations of the reflector housing is made possible.
The reflector housing 12 mounts a bayonet-type lamp socket 54 (FIG. 4) that detachably receives an incandescent lamp bulb 56 in a conventional manner. A conical reflector 58, made of white plastic or the like, is secured in any suitable manner to the inside of the cylindrical reflector housing 12 to surround the bulb 56. A translucent rim 60 is fitted in the end of the housing 12. The lamp 56 is located well within the open end of the housing 12.
The molded plastic base 16 has an interrupted, generally cylindrical extending flange 62 (FIG. that fits the opening at the bottom of the base housing (FIG. 4). The interrupted flange 62 projects from a shoulder 64 that abuts the bottom edge of the housing 10. The periphery of the base of the closure 16 beyond the shoulder 64 forms a smooth continuation of the housing 10. The closure 16 may be held in position by screw or other conventional means.
The closure 16 has an access aperture 66 for a lead cord 68 that connects to the primary winding of a transformer 70. The transformer 70 has square laminations 72 seated upon the cap or closure 16. As shown in .FIGS. 5 and 7, the closure 16 is formed to provide two parallel, downwardly opening channels 74 and 76 that extend entirely across the closure 16. The transformer laminations 72 rest upon the inner surfaces of these channels 74 and 76, substantially as shown in phantom lines in FIG. 5. A sponge or foam rubber pad 78 is interposed between the laminations and the channels 74 and 76.
A molded plastic insert 80, fitted within the hollow base housing 10, holds the transformer against the closure 16. The insert 80 comprises two channels 82 and 84 (FIG. 6) secured along the inside of the base 10, and a connector plate 86 joining the channels. The lower ends of the channels are spaced just above the closure 16 at the bottom of the housing 10, as shown in FIG. 4, and the connector plate 86 is located near the top of the housing 10.
Depending from the connector plate 86 are two integrally molded pins 88 and 90 (FIGS. 4 and 6) that contact the upper portions of the laminations 72 and thus hold the transformer 70 against the closure 16. Part of the windings of the transformer 70 on one side of the laminations projects between the channels 82 and 84, whereby the transformer 70 is restrained against rotation and accordingly held in substantially fixed position in the base 10.
The secondary windings of the transformer 70 connect to a radio-type switch assembly 92 that is mounted upon the connecting plate 86. Thus the switch assembly 92 has a shaft 94 that projects upwardly through an aperture in the plate 86, and a nut 96 secures the switch assembly in position in a conventional manner. Leads from the switch 92 and the transformer windings extend through the lateral aperture 48 in the housing 19 and thence are threaded through the hollow arms 24 and 22 and through the hollow pin 38 into the reflector housing 12 for connection to the lamp socket 54.
Closing the top of the base housing 10 is the knob 18. This knob has a downwardly extending boss 98 in which the shaft 94 is press-fitted. The knob has an arcuate flange that extends substantially 270 about the top edge of the housing 10, as shown in FIG. 3. The edges of the flange are knurled in order to provide a suitable grip. A recess 100, formed by the ends of the flange, provides the requisite clearance with the hinge assembly 42 f0 rangular movement of the knob 18 to any one of three switch positions. Furthermore, the assembly 42 limits such angular movement.
The switch assembly 92, in addition to an off position, has a relatively high-voltage position and a relatively lowvolta ge position for relatively highand low-intensity energization of the lamp 56.
A stabilizing foot 102 may be projected from either side of the base 10, and as indicated in FIG. 10, thus to support .the lamp in situations where the reflector housing is positioned laterally in one direction or the other, as indicated in full and dotted lines. The foot 102 is generally of U-shaped configuration, as shown in FIG. 7, and made of resilient, thin, rectangular bar stock material. The legs 104 and 106 extend through recesses 108 and 1110 (FIG. 5) formed in the bottom of the channels 74 and 76. The free ends of the legs 104 and 106 may be projected upwardly (FIGS. 6 and 7) into the spaces provided by the channels 82 and 84 of the insert 80. The bottom of the closure 16 has a shallow recess 112 (FIGS. 2 and 4) that receives the connecting portion 114 when the foot is in the retracted position shown in FIGS. 5 and 6. The recess 112 is sufficiently wide to allow the connecting portion 114 to be grasped by the fingers and pulled downwardly.
Lateral projections 116 and 118 (FIG. 7) at the ends of the legs 104 and 106 form stops limiting outward movement of the foot 102. These projections 116 and 118 engage V-shaped bearing recesses .120 and 122 FIGS. 4 and 5) formed in the outer side walls of the channels 74 and 76 and adjoining the slots 108 and 110. The apices of the recesses and 1 22 are located intermediate the depth of the channels 74 and 7 6, whereby the foot, when in a downwardly projected position, can be swung either to the right or to the left to enter the downwardly opening channels 74 and 76, and as indicated in FIG. 2. When the foot 102 is in the retracted position of FIG. 7, the legs 104 and 106 are slightly flexed apart by protuberances 124 and 126 (FIGS. 6 and 7). A frictional restraint is thus imposed whereby the foot is held in its retracted position.
The lamp is capable of a wide variety of uses. In FIG. 8, the lamp is shown with the arms 22 and 24 folded and the reflector housing 12 in juxtaposed relationship to the base 10. 'In this instance, the lamp may be used as a night light by turning the knob 18 to the lowvoltage position. Illumination will pass outwardly through the translucent rim 60. Since the hinge 32 is situated midway along the length of the housing 10, it may be inverted, as illustrated in FIG. 9, thus to cast a beam of illumination upwardly for broad illumination purposes. In FIG. 10, alternate operative positions of the lamp and foot are illustrated. In FIG. 11, the lamp is shown installed in a wall 128 by the aid of a bracket 130. The bracket is in the form of a simple strap that may be attached to the wall, as by screws 132 and 134. A connecting portion of the strap provides a recess for passage of the foot 102, and the edge of the connecting portion provides an arcuate seat 166 for the cylindrical exterior of .the base 10. In FIG. 12, the lamp is shown in the same position as in FIG. 8, except that the foot is telescoped within the housing, and the lamp is positioned by hand.
The lamp shown in FIGS. 14 to 16, except as hereinafter described, is similar to the lamp shown in the previous form.
In the present instance, the reflector housing 140 telescopes over the operating knob .142. The upper end of the lower lamp part 144 has an inwardly extending flange 146 (FIG. 15) that isengaged by the translucent rim 1 48 when the lamp is closed. The edge of the knob 142 partially overlies the flange 146.
The knob 142 cooperates with a switch (not shown) that has a substantial number of operating positions. The transformer has a corresponding number of taps whereby the lamp intensity is adjustable in small increments. A pointer 150, cast into the lower lamp part, cooperates with scale indications on the face of the knob.
The end closure 152 (FIG. 16) carries an annular suction cup 154 that serves to stabilize the lamp. At the center of the closure 152 is a keyhole slot 136 accessible through the annular suction cup. This slot .126 may cooperate with a headed screw or the like whereby the lamp may be mounted on a wall.
In the present instance, the arms 158 and 160 each include extensible parts.
