ROOM DIVIDER LAMP CONSTRUCTION Filed Jan. 18, 1960 INVENTOR. /)nr mY/V: ze l 1 F/at X United States Patent ROOM DIVIDER LAMP CONSTRUCTION Filed Jan. 18, 1960, Ser. No. 3,014

4 Claims. (Cl. 240-81) My invention relates to improvements in room divider lamp construction.

My invention relates more particularly to refinements in the same by the use of which better construction, easier assembly and easier use of the same may be obtained.

Room divider pole lamps of the type to which I refer are usually provided with a three-section pole and a pair of spring mounted foot members for positioning the same between the ceiling and the fioor of a room in which they are used. With the usual type of room divider pole lamp now in use there is very little bearing surface for the rods of the foot portions, with the result that very frequently the room divider itself will be canted in position and thus look unbecoming. The short bearing for the foot rod which is usually only the thickness of the metal at the hole through the pole caps thus permits of possible bending or canting and results in an untidy appearance in use.

' The principal object of the present invention is to provide an improved construction of room divider lamp or pole lamp.

A further object of the invention is to provide such a construction which will result in an improved appearance and in more workmanlike action.

A further object of the invention is to provide a pole lamp having suitable bearing members at both ends of the same.

A further object is to provide an improved room divider or pole lamp which permits the wiring of the same without threading the wire through openings in the pole cap at either end.

Another object of the invention is to provide an improved pole cap for use in room divider lamp construction.

Other objects and advantages will be more apparent from the following description wherein reference is had to the accompanying drawings, upon which:

Fig. l is a side elevational view showing a room divider lamp in position between the floor and the ceiling of a room;

Fig. 2 is a full size fragmentary vertical sectional view with the portion between the two ends of the lamp post foreshortened;

Fig. 3 is a cross-sectional view the line 33 of Fig. 2;

Fig. 4 is a fragmentary side perspective view of a portion of the lamp post and foot supporting rod; and

Fig. 5 is a bottom plan view taken generally on the line 55 of Fig. 4.

In the embodiment of the invention which I have chosen to illustrate and describe the same, the usual type of room divider lamp is shown and may include the tubular post member which is usually made of three sections, the upper and lower sections 12 and 14 having the end 16 telescopically received in the center section 20. The adjustable lamps 22 are also mounted in the center post 20 and have the extension wire 24 connected thereto, the

therethrough, taken on rod, butrather it is held slot connection as described, the

extension wire being passed through a rubber grommet that is mounted in an elongated slot 28 at the lower end of the tubular portion 14. The electric cord is provided with the usual push-in plug 30.

As previously stated, the usual room divider lamp is provided with a pair of foot members which include the foot rod 32 and the pad 34 that bears against the ceiling C and the floor F to support the lamp in position. The rods 32 normally pass through end caps at the upper and lower ends of the pole sections 12 and 14. In the construction shown, I provide a top pole cap 40 Which is mounted by means of a bayonet slot connection in the upper end of the tubular member 12.

The bayonet slot connection may include the pins 42 fastened in the tube 12 adjacent its open end, the pins riding in suitable bayonet slot grooves 44 in the surface of the body 46 of the cap 40 in the usual manner.

In order to provide a smoother and more easily operable construction and one which is sturdier in use, I have provided an elongated sleeve portion 48 as part of the cap 40, the sleeve portion 48 forming an elongated bearing for the rod 32. The rod 32 and pad 44 are usually pressed upwardly in the tube 12 by means of a coiled spring member 50 below the lower plate 52 attached to the rod 32, thus permitting vertical adjustment for ceilings of various heights. The lower cap member 60 may also be mounted in the end of the tube by means of a bayonet cap 60 also having an elongated sleeve portion 62 which forms a sliding bearing for the bottom foot rod 32.

The bottom foot rod 32, which may be approximately 18 inches long, is not spring pressed as is the upper foot in place by a thumb screw 64 which engages the post, being mounted in a tapped hole 66 in a boss 68 at the lower end of the cap 60. This boss may preferably have the flattened sides 70 as shown, so that it may easily be grasped with a pliers or wrench to engage or disengage the bayonet slot from the pins 42.

The bottom cap 68, as best shown in Figs. 2 and 3, proides a space for the cord 24 to the elongated slot 28 in the lower end of the tubular member 14, being cut off to form a sector-shaped opening by means of the side walls 82 and 84 of the body portion 46.

With the above and foregoing construction, it is an easy matter, when the a home in a disassembled manner, to connect the cord 24 from the lamp post 20 by dropping the plug and cord through the tubular member 14, placing the grommet 26 that is on the cord up into the slotted opening 28, so that both the cord and the grommet are held in fixed position. The lower cap member 60 may now be easily fastened in place without disturbing the cord 24 by reason of the sector-shaped cavity 80 provided in the cap.

By making the lamp divider with a spring-pressed foot 32 and an adjustable foot 32 at the bottom, the room divider lamp can be positioned equally between the floor and the ceiling and fastened by means of the set screw 64, thus enhancing the appearance of the room divider lamp and providing a better fixture between the top and bottom supports for the same.

While I have illustrated and described a specific embodiment of the invention, it will be apparent to those skilled in the art that changes and modifications may be made in the exact details shown and I do not wish to be limited in any particular; rather what I desire to secure and protect by Letters Patent of the United States is:
