Description

y 1941.- P. P. GRABOWSKY 4 2,240,987
CURTAIN OR SHADE BRACKET Filed Jan. 26, 1959 E287 .P. 6 INvI-INTOR ATTO R N EYS ?atented May 6, 1941 UNITED STATES PATENT OFFICE 1 Claim.
My invention relates to mounts for window shades and the like, and has for one of its principle objects the provision of novel means for mounting the shade in such manner as to prevent accidental displacement of the winding stem of the shade roller.
In the accompanying drawing:
Figure 1 is an elevational view of a small portion of a shade illustrating my invention applied to the winding stem thereof.
Figure 2 is an elevational view of the shade bracket; and
Figure 3 is a sectional view along the line 3--3 of Figure 2.
Referring to Figures 2 and 3, the shade bracket it comprises wings I2 and I4 which lie in a common plane to be positioned against the face it of the window frame. Wings I2 and I4 are interconnected through the medium of a semispherical shell l8, all of which parts are stamped from a fiat piece of sheet metal having an original outline conforming substantially to the configuration of Figure 2. Shell I8 is provided with a rectangularly shaped opening 20 for the reception of the winding stem 22 of the shade roller 24. Winding stem 22 fits quite snugly in the opening 28 in the manner of conventional shade brackets. Means is provided for restraining the winding stem from accidental displacement. To this end, I provide a spring finger 25 which comprises material of the blank from which the bracket is formed. The originally flat piece of material is severed along the lines 28, 30 and 32, with the lines intersecting in the manner illustrated in Figure 2, so that the finger is characterized by one free end with its opposite end integrally connected with the wing l2. Thus the bracket illustrated in Figure 2 is characterized by a slot 34 formerly occupied by the spring finger 26, with the free end of the finger having its edge 30 paralleling and substantially aligned with the edge 36 of the opening 20. Figure 3 illustrates the free end of the finger 26 as lying inside the slot 34 at the point 38 so that the free end may be depressed when the winding stem 22 is forced thereagainst preparatory to being pushed into the opening 20. Thus the spring finger 26 provides an effective means for latching the winding stem 22 inside the opening 20 so as to effectively prevent accidental displacement of the winding stem.
Wing l4 includes a slot 40 for the reception of a screw 42 which may be threaded into the frame 44. Similarly, the wing i2 is provided with two openings 46 for the reception of screws 48 which are also anchored in the frame 44. In addition to providing an effective latch means for the winding stem of the shade roller, my bracket comprises a single piece of material which is formed by a simple stamping process.
I claim:
A bracket for mounting a curtain shade comprising a single piece of sheet metal fashioned to provide anchoring wings and a semi-spherical shell, said shell being provided with a rectangularlyshaped opening in its apex, and said shell and one of said wings being severed and the material between the lines of severance bent to provide a resilient finger and a slot underneath the finger, said slot leading into said opening, said resilient finger having its free end located at the apex of said shell and a portion of the end of the finger comprising in part a wall of said opening, said finger being depressible through said slot to yield for permitting the winding stem to be moved through the slot and into said opening.
