Feb. 28, 1956 R. E. BELL ANTIFRICTON EXTENSION ROD AND TRACK Filed Sept. 30, 1953 H'T'TORNEYS United States Patent ANTIFRICTION EXTENSIDN ROD AND TRACK Ralph E. Bell, Sturgis, Mich., assignor t0 Kirsch Company, Sturgis, MiclL, a corporation of Michigan Application September 30, 1953, Serial No. 383,295
6 Claims. (Cl. 16-95) This invention relates to curtain rods and particularly to those which form a slideway for curtain-supporting slides. The invention relates particularly to hollow slotted curtain rods which are ordinarily formed with a C- shaped cross section and more particularly to extension rods of the type in which a pair of telescoping sheet metal sections are telescoped together to provide a rod having a longitudinal slot therein to receive the curtain-supporting slide or the like.
One of the objects of the invention is to provide a rod of the above type which has a track which will provide smooth and relatively frictionless silent operation as the slides move along the way.
Another object is to provide such a rod of theextension type which has a smooth relatively frictionless way for the curtain-supporting slides and in which catching at the juncture of the telescoping sections is eliminated.
Other objects of the invention will appear from the description to follow.
For the purpose of illustrating the invention there is shown in the accompanying drawings a form thereof which is at present preferred since it gives satisfactory and reliable results, although it will be understood that this form of the invention is. shown by way of illustration only.
In the drawings,
Fig. 1 is a rear elevation of a curtain rod embodying the invention.
Fig. 2 is a detailed sectional view taken on the line 22 of Fig. 1.
Fig. 3 is an enlarged section taken on the line 33 of Fig. l, and
Fig. 4 is an enlarged section taken on the line 4-4 of Fig. 1.
In general the invention consists in providing a curtain rod which has a way thereon which receives a curtain-supporting slide which slides therealong with a suitable anti-friction track which may be easily and simply applied thereto. Such track is made of resilient plastic material such as Nylon.
In one common form of the invention the rod consists of sheet metal formed into C-shaped cross sections. There are a pair of partially overlapping telescoping sections which are so telescoped as to provide a telescoping rod way longitudinal slot therein. Combined with this rod is the track made of plastic material such as Nylon in the form of a strip having a longitudinal groove therein which fits over the sheet metal of the sections at one edge of the longitudinal slot in the rod. The lateral dimension at the bottom of this groove is at least twice as great as the thickness of the sheet metal of one of the sections and its walls converge from the bottom toward the top of the groove to provide an opening which is spaced from the bottom of the groove and has a lateral dimension which is not greater than the thickness of the sheet metal forming one of the sections so that the material will frictionally grip the sheet metal and hold the track in place. The track can thus receive a dual thickness of sheet metal Where the sections overlap and also may retain and be frictionally engaged by the resilient material in position on one edge of the slot throughout the length of the rod in the portions thereof where the sections do not overlap and only a single thickness of metal in inserted in the groove.
The extension rod is shown generally at 1. It is formed of sheet metal which is bent to a C-shaped form shown in section in Fig. 2. It consists of sections 2 and 3 which telescope as indicated in Fig. 1 to give a rod which has a longitudinally-extending slot 4, which is adapted to receive slides 5 which support curtains, drapes or the like.
Along one edge of the slot 4 is provided a track 7 which consists of a strip of resilient plastic material such as Nylon. In this strip is provided a groove 8 which has a lateral dimension at its bottom 9 which is at least twice as great as the thickness of the sheet metal which makes up the sections. The walls 10 of the groove converge toward one another as is best shown in Figs. 2 and 3 to form an opening, indicated at 11, which has a lateral dimension not greater than the thickness of the sheet metal of one of the sections.
It will be apparent that with this arrangement the groove 8 can receive two thicknesses of sheet metal as shown in Fig. 4, the resilient walls 10 being forced apart to receive the metal. The resiliency of the material forces the walls 10 into frictional gripping engagement with the sides of the sheet metal, as indicated, and holds it in place.
At the portions of the rod where the sections 2 and 3 do not overlap, as is best shown in Fig. 3, the resilient walls 10 still exert frictional gripping force on the side of the sheet metal and retain the track 7 in place.
When the track 7 is used on an extension rod, as shown in Fig. 1, the track 8 forms a completely smooth continuous surface running from end to end of the rod and at the overlapping portions of the sections the track eliminates any material bump caused by the ends of the sections, thus permitting the slides to move freely back and forth without catching as they sometimes. do when they slide merely on the sheet metal edge of the slot in a rod such as that shown here.
In commercial practice the extension rod is. sold to fit a variety of window widths. A section of track having a length equal to the greatest possible extension is supplied with each such extension rod. If the full extension is not to be employed the track may be cut to the desired length and inserted on the rod.
The present invention may be embodied in specific forms other than the forms shown by way of illustration without departing from the spirit or essential attributesof the invention, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention.
