Our invention relates to a curtain rod.
It is the principal object of the invention to provide a curtain rod which may be quickly adjusted to length and which may be put up without brackets and without the use of tools.
Another object is to provide a readily adjustable curtain rod which is simple in construction,
cheap to manufacture, of few parts, and effective in use.
Other objects will be hereinafter pointed out or will become apparent upon a reading of the specification.
, In the drawing which shows, for illustrative purposes only, a preferred form of the invention- Fig. 1 is a view in elevation of a curtain rod illustrating features of the invention and showing the rod applied; and
Fig. 2 is an enlarged fragmentary view of the rod, parts beingbroken away.
Our improved rod includes a pair of telescopic or relatively slidable rod members which in the formshown comprise a hollow tubular rod5 and an inside rod 6, which may be solid and is slidably received in the hollow rod 5. The free ends of the rods 5 and 6 are provided with holding members,
such as friction rubber caps 1-1, which may engage the sides of a window casing or the sides of a door frame or other surfaces, herein generally termed wall surfaces.
When in use the rod members are urged telescopically outwardly so as to cause the opposite ends of the rod to frictionally and tightly grip opposite wall surfaces. One of the rod members carries a spring positioned to abut the end of the other rod member, so asto urge the rod members outwardly relatively to each other. The spring is adjustable on one of the rods so that, regardless of the extension of the rod, the frictional hold-' ing forces may be the same. By this means the eiiective overall length of the rod may be varied to adapt it to window casings, for example, of different widths. In the form illustrated a coil spring 8 is carried by and surrounds the rod 6 and the free end of the spring is of a size to abut the end of the rod 5 or a finish piece or ferrule 9 thereon. The spring 8 is held in various adjusted positions on the rod 6 so as to permit extension of the rods and adjustment of the spring holding forces. The rod 6 is provided with means, such as a spiral thread in the form of a groove l0, extending substantially throughout a substantial portion of its length and the spring 8 at one end is reduced so as to fit the groove Ill and form in effect what may be termed a spring nut, formed by one or more of the several coils ll fitting in the groove 10. It will thus be seen that when the spring 8 is turned on the rod 6 the spring will be shifted longitudinally on the rod and the two rods therefore adjusted relatively to each other. Furthermore, by having the spring adjustable at will on the rod, the extent of the friction forces to hold the rod in place may be adjusted to the desired extent within the limits of the particular spring employed. Our improved rod, it will be noted, may be very quickly and readily applied to window casings, door openings and the like, of varying widths. It may be caused to hold with the desired force within the limits of the spring and any wear or give in the parts will be readily taken up by the spring 8.
While the invention has been described in considerable detail and a preferred form illustrated, it is to be understood that various changes may bemade within the scope of the invention as defined in the appended claims.
1. In a curtain rod, a pair of telescopic rod members, a spring surrounding one of said rod members and engageable with the other rod member, one of said rod members having a thread thereon and said spring having an end reduced so as to fit said thread, whereby upon rotation of said spring on its rod the spring and rod will be moved relatively to each other, for the purpose described.
2. In a curtain rod, a hollow tubular rod member, a solid rod member telescopically received within said hollow rod member, said solid rod member having a spiral groove thereon, a wire nut received in said groove, saidwire nut being extended into spring form and engageable with the end of said hollow tubular rod, for the purpose described.
3. In a curtain rod, a pair of telescopic rod members, frictionmembers secured on the free ends of said rod members, the inner of said telescopic rod members having a spiral spring thereon engageable with the other of said telescopic rod members, and means on the outside of the inner of said telescopic rod members for holding one end of said spring in adjusted position there- 4. In a curtain support, two rods slidable one within the other, a spiral coil spring mounted on the outside of the inner rod, one end bearing against the end of the outer rod, and means on the outside of the inner rod to hold the other end of said spring to different positions thereon to vary the effective overall length of said support.
