1 Claim.

This invention relates to improvements in window blind fixtures its primary object being to provide a fixture that maybe easily installed.

A further object is to provide a fixture that may be installed with a minimum of damage to window frames.

A still further object is to provide a fixture that will be efiicient and durable and inexpensive to manufacture.

With these and other objects in view that may appear while the description proceeds the invention consists in the novel construction, and arrangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawing forming part of this specification and in which:

Fig. 1 is a perspective view of the end of the fixture attached to the rotating end of the blind.

Fig. 2 is a similar view of the end of the fixture attached to the fixed or spring end of the blind.

Figs. 3 and 4 are modified views of the fixture combining the use of a detachable screw.

Fig. 5 is another modified view of the fixture.

Fig. 6 is a View showing the method of forming the base of the fixture as shown in the modified view in Fig. 5.

Referring more in detail to the drawing in which similar reference characters designate corresponding parts throughout the several views it will be seen that the invention comprises a pair of bases l0, Illa, having side pieces I I, I la, angularly disposed thereto.

The side pieces ll, Ila, are identical with the exception that the end of side H, has a hole l2, to receive the rotating end of the blind roller while side Ila, has a slot l3, to hold the fixed or spring end of the blind roller in position. Having this in mind, the base In, is the only one that need be hereinafter referred to for the purpose of this invention.

A threaded screw I4, is secured to the base Ill, so that the fixture may be attached to the window frame by turning by hand, and the head of the screw 14, is provided with a conventional slot l5, so that if desired a screw-driver maybe used to attach the fixture to the window frame.

In the modified form of the fixture as shown in Figs. 3 and 4, a groove 16, is cut in the base In, Ilia, are shoulder retaining means associated with groove l6, I1, is a threaded screw having a square cut shoulder l8, which engages in the groove l6, enabling the fixture to be attached to the window frame by turning by hand. The head of this screw l1, also is provided with a conventional slot so that a screw driver may be employed to attach the fixture to the window frame it desired.

Fig. 5 shows a further modification of the fixture in which the threaded portion I9, is an integral part of the base l0, permitting the fixture to be attached to the window frame simply by hand turning. The method of forming this threaded portion I9, is clearly shown in Fig. 6, in which the center part 28, of the base I, is stamped out by means or dies 2 I. 22 and becomes the threaded portion l9. 7

It is believed that the construction and advantages of the device may be apparent from the foregoing paragraphstaken in conjunction with the accompanying drawing without further de- A shade fixture comprising a base having an angularly disposed portion forming a shade supporting arm, said base having a slot therein opening through an edge thereof, a screw shank having a head and a, square shoulder beneath said head of corresponding width to the slot of said base and adapted to engage in the slot, and lugs projecting from the edges of the slot for engaging the shoulder of said screw shank to retain the same in said slot.
