3 Claims.
This invention relates to a lamp.
The object of the invention is to provide a lamp which is attractively and artistically constructed, and which is easily and safely operated. Y
VAnother object of' the invention isto provide a lamp which will efficiently diffuse light, as for reading, and which can be turned on and oil by simple manual operation.
A further object of the invention is to provide a lamp which is extremely simple and inexpensive to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:
Figure 1 is a side elevational view of the lamp, according to the present invention;
Figure 2 is a Vertical sectional view of the lamp;
Figure 3 is a fragmentary vertical sectional View of the lamp, showing the position of the parts thereof when the'switch is being actuated;
Figure 4 is a top plan view ci the lamp;
Figure 5 is a bottom plan view of the ring;
Figure 6 is a, sectional view taken on the line 6 6 of Figure 2; Y
Figure 7 is a sectional view taken on the line 'l-'I of Figure 2.
Referring in detail to the drawings, the numeral 26 designates a base which may be fabricated of a suitable plastic. The base 29 is provided with a bottom member 2| and projecting upwardly therefrom is a vertically disposed cylin- 5 The flange 22 is provided with drical flange 22. a plurality of spaced vertically'disposed slotsr or recesses 23 fora purpose to be later described. The base 26 is provided with an annular skirt 24 which adds to the esthetic appeal of the lamp and also insures that the lamp will not topple over.
The bottom 2| of the base 20 has projecting therefrom a socket wall and supported on the bottom 2| is a suit/able globe or light bulb 26. The cable 2l is connected to a suitable source of electrical energy, and one line 28 of the cable is arranged in engagement with a contact 29 that is electrically connected to the bulb 26. The other line 30 leads from the cable 2l to an On and Off switch 3|, there being a line 32 electrically connecting the On and Off switch 3| to the Contact 33 in order to provide the complete electrical circuit for the light bulb 26.
Slidably arranged within the iiange 22 of the base 20 is a ring 34 which is provided with a (Cl. 24U- 123) 2 Y plurality of spaced compartments 35. A coil spring 39 is positioned in each of the compart. ments 35 for normally urging the ring 34 to its Vraised position as shown in Figure 2. The ring 34 is provided with a plurality of spaced ribs 3l whichvride in the slots 23 in the flange 22 in order to insure the correct alignment between the ring and base. The ring 34 includes a horizontally disposed lip 38 which is engaged by or contacted by the lower edge of a globe 39. The ring 34 has secured thereto a brace 49 which is adapted to actuate the switch 3| when the inner ring 34 is forced or moved downwardly by the globe 39.
The globe 39 includes a cylindrical wall 4| which .slidably seats in the flange 22, there being a plurality of spaced ribs 42, Figure '7, projecting from the wall 4| for registering with or engagement with the slots 23 in the flange 22. The globe 39 is provided with a window or cutout 43 for the passage or dilusion therethroughcf the light emitted by the bulb 26. The upper end of the globe 39 is arcuate and is adapted to be engaged by a persons hand to depress the globe 39 and thereby move the ring 34 down wardly to actuate the On and Off switch 3|.
Arranged in embracing relation withV respect to the globe 39 and rotatably mounted on the latter is a cylindrical shade 44.
From the foregoing, it is apparent that a lamp hasvbeen provided which is extremely artistically designed and which can be safely and readily actuated. To actuate the lamp, the user presses downwardly on the globe 39 thereby moving the ring 34 downwardly against the tension of the coil springs 36. This downward movement of the ring 34 actuates the switch 3| since lthe brace is carried by the ring 34 and'is arranged in engagement with the switch 3|. As soon as the downwardly directed pressure on the globe 39 is'released, the springs 36 return the ring V34 to its raised position, as shown in Figure 2.
The complete lamp is made of a minimum number of parts and the various parts are preferably molded of a suitable plastic, such as the phenolic type. The shade `44 can be rotated or revolved readily on the globe 39 and the shade is preferably fabricated of a transparent plastic, and if desired, a suitable color scheme can be provided for the various parts of the lamp in order to increase the attractiveness thereof. The shade 44 has one third of its circumference of area transparent or clear of any color, While the remaining two thirds of the shade is tinted any desired color. Thus, when the lamp is being used, as a reading lamp in a bedroom, the transparent section can be revolved so as t0 register with or be in front of the globe 43 whereby the light rays can readily pass therethrough. By turning or rotating the shade 44 180, the lamp will emit a soft colored subdued light. Further, the top of the globe 39 may be translucent and may be of any desired color. The base `2l) can readily be molded of suitable plastic so that the cost of manufacturing the latter will be very small. The switch 3l is conventional and has one push button 45 which must be pressed down each time to either make or break electrical contact. The electric light bulb 26 can be readily replaced by removing the shade 44 and removing and replacing the bulb through the window 43.
Further, the various parts of the lamp may be made of other suitable material such as glass. Also, the external lconfiguration of the lamp may be inthe shape of a nursery story animal, such as a bear or pig whereby the salability of the lamp would be increased as an item for chil-V drens rooms. Thus, the lamp is readily and especially vsuitable Afor a childs lamp, since there is relatively few parts and further, the lamp is readily actuated.
