Description
BACKGROUND OF THE INVENTION

1. Field of the Invention


The invention generally relates to an apparatus for hanging a curtain rod, and in particular relates to a vertically adjustable rod support assembly for selectively supporting a curtain rod and curtain at an elevated height within a window frame, and for enabling a user to lower the vertical height of the curtain rod in order to attach or detach the curtain from the rod, without the need for standing upon a ladder or another object.


2. Description of the Related Art


Curtain rods, used for hanging curtains within an existing window having a window frame, add greatly to the aesthetic appeal of the window frame, and also provide the occupants of the room with a measure of privacy. However, curtain rods have a notable drawback. In particular, because a curtain rod is generally attached at a vertically elevated position within the window frame, an individual who wants to replace the curtain with one having a different design must ordinarily stand upon a ladder or another object in order to reach the curtain rod. The process of standing upon a ladder to reach a curtain rod in order to remove a curtain is an arduous one, and causes many thousands of accidents every year. Accordingly, there is a need for a vertically adjustable rod support assembly for selectively supporting a curtain rod and curtain at an elevated height within a window frame, and for enabling a user to lower the vertical height of the curtain rod in order to attach or detach the curtain from the rod, without the need for standing upon a ladder or another object.


A variety of adjustable height rod supporters have been devised. For example, U.S. Pat. No. 4,418,882 to Waring appears to show an adjustable height rod supporter comprising a first roller track containing a first guide roller, a second roller track containing a second guide roller, and a rod attachment bar secured to a first support shaft, for supporting a rod at various heights. Moreover, U.S. Pat. No. 6,409,139 B1 to Du Pree appears to show an adjustable height rod supporter which comprises a housing, a spring, an insert, and a cradle mounted on the insert, for providing vertical support to an existing rod.


While these devices may be suitable for the particular purpose employed, or for general use, they would not be as suitable for the purposes of the present invention as disclosed hereafter.


SUMMARY OF THE INVENTION

It is an object of the invention to provide a vertically adjustable rod support assembly for selectively supporting a curtain rod and curtain at an elevated height within a window frame, and for enabling a user to lower the curtain rod within the window frame, in order to attach or detach the curtain from the rod, without the need for standing upon a ladder. Accordingly, the vertically adjustable rod support assembly has two pulley assemblies, each having a selectively movable rod support attached thereunto. The rod supports are used for supporting the curtain rod. The pulley assemblies are used to selectively lower the rod supports and the curtain rod supported thereupon, and thereby enable the user to lower the curtain rod within the window frame, without the need for standing upon a ladder.


Further objects of the invention will become apparent in the detailed description of the invention that follows.


The invention is a vertically adjustable rod support assembly for selectively supporting an existing curtain rod and curtain at an elevated height within an existing window frame, and for enabling a user to lower the vertical height of the curtain rod in order to attach or detach the curtain from the rod, without the need for standing upon a ladder or another object. The vertically adjustable rod support assembly comprises two guide tracks, two pulley assemblies, and two selectively movable rod supports, each attached to a different pulley assembly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS


FIG. 1 illustrates a vertically adjustable rod support assembly 10, being used in conjunction with an existing window 54 having a window frame 56 having lateral sides 56S having an existing elongated curtain rod 50 extending therebetween, said curtain rod 50 having an existing curtain 52 hanging vertically downward therefrom. The curtain rod 50 is being selectively supported by the rod support assembly 10 at a vertically elevated position within the window frame 56. The rod support assembly 10 allows a user to selectively adjust the vertical height of the curtain rod 50 so that the user may attach or detach the curtain 52 therefrom without the need for standing upon a ladder or other object in order to be able to reach the curtain rod 50. The rod support assembly 10 comprises two substantially cylindrical guide tracks 16, each of which is selectively vertically mounted in proximity to a different one of the two lateral sides 56S of the window frame 56, and each having an upper end 16U and a lower end 16L. The upper end 16U of each of the guide tracks 16 has a pulley assembly 11 attached thereunto.


Turning to FIG. 3, each pulley assembly 11 comprises a pulley wheel housing 34 which encloses a selectively rotatable pulley wheel 36 having a grooved rim around its perimeter, an axle 38 which extends concentrically through the pulley wheel 36, and a nylon cord 18 which is looped over the grooved rim of the pulley wheel 36 and which selectively slides thereupon. The pulley wheel housing 34 has a lower end 34L which is affixed to and supported upon the upper end 16U of the guide track 16. The lower end 34L has two openings 34P extending fully therethrough, through which the cord 18 selectively extends. The cord 18 is preferably several feet long and has a first end 18A having a hook 30 attached thereunto, and has a second end 18B having a grasping handle 32 attached thereunto.


Returning to FIG. 1, the rod support assembly 10 further comprises two selectively movable curtain rod supports 12, for selectively supporting the elongated curtain rod 50 having a first end and a second end. Each rod support 12 comprises a vertical arm 22 and a horizontal arm 24. The horizontal arm 24 has an upper surface 24U having a vertical slot 22S for selectively supporting one of the ends of the curtain rod 50. The vertical arm 22 has an upper end 22U having a circular opening 28 extending therethrough. The hook 30 at the first end 18A of the nylon cord 18 extends through the circular opening 28 within the vertical arm 22, in order to attach the rod support 12 to the first end 18A of the nylon cord 18. When the user grasps and pulls downward upon the grasping handle 32 at the second end 18B of the nylon cord 18, this causes the hook 30 at the first end 18A of the nylon cord 18 to vertically raise, thereby also vertically raising the attached rod support 12, and thereby causing the curtain rod 50 resting upon the curtain rod supports 12 to also be selectively vertically raised. When the user releases the grasping handle 32 at the second end 18B of the nylon cord 18, this causes the hook 30 at the first end 18A of the nylon cord 18 to vertically lower, thereby also vertically lowering the attached rod support 12, and thereby causing the curtain rod 50 resting upon the curtain rod supports 12 to also be selectively vertically lowered. The movable rod supports 12 permit the user to selectively lower the curtain rod 50 so that the curtain 52 can be easily removed therefrom, without the need for climbing upon a ladder or another object. It is contemplated that the rod support assembly 10 may be provided with a cord locking mechanism for selectively immobilizing the cord 18, in order to selectively maintain the rod supports 12 at an elevated height.


The vertical arm 22 of each of the rod supports 12 has an attachment ring 26 extending therefrom. A different one of the two cylindrical guide tracks 16 extends concentrically through each of the two attachment rings 26. The attachment rings 26 selectively slide vertically upon the guide tracks 16 when the user pulls downward upon or releases the grasping handle 32 at the second end 18B of the nylon cord 18, while raising or lowering, respectively, the rod supports 12, and the curtain rod 50 selectively supported thereupon. The guide tracks 16 are used for stabilizing and constraining the lateral motion of the rod supports 12 as they selectively move vertically.


The cylindrical guide tracks 16 each have at least two attachment tabs 40 extending therefrom, for selectively attaching the guide tracks 16 to the lateral sides 56S of the window frame 56. Each of the tabs 40 has a circular opening 40A extending fully therethrough. The assembly 10 is provided with threaded mounting screws 20 for mounting the guide tracks 16 to the lateral sides 56S of the window frame 56. In particular, the user attaches the guide tracks 16 to the lateral sides 56S of the window frame 56 by extending a mounting screw 20 through each of the circular openings 40A of the tabs 40, and by threading the screws 20 into one of the lateral sides 56S of the window frame 56.



FIG. 2 illustrates a view of the rod support assembly 10, as in FIG. 1, except that the curtain rod 50, and the curtain 52 hanging vertically downward therefrom, have been vertically lowered within the window frame 56 in order to allow the user to easily remove the curtain 52 from the curtain rod 50.


The components of the rod support assembly 10, with the exception of the cord 18, are preferably constructed from a durable metal. The rod support assembly 10 is provided in different sizes so that it may be suitably used with window frames 56 having lateral sides 56S having different lengths.


In use, the user vertically attaches the guide tracks 16 to the lateral sides 56S of an existing window frame 56 with the mounting screws 20 provided for this purpose. The user vertically lowers the attached rod supports 12. The user positions a curtain 52 upon an existing curtain rod 50. The user supports the curtain rod 50 within the vertical slot 22S of each of the rod supports 12. The user grasps and pulls downward upon the grasping handle 32 at the second end 18B of the nylon cord 18, in order to vertically raise the attached rod supports 12, and thereby causes the curtain rod 50 resting upon the curtain rod supports 12 to also be selectively vertically raised to an optimal position. When the user wants to remove the curtain 52 from the rod 50, the user releases the grasping handle 32 at the second end 18B of the nylon cord 18, thereby vertically lowering the attached rod supports 12, and thereby causing the curtain rod 50 resting upon the curtain rod supports 12 to also be selectively vertically lowered.


In conclusion, herein is presented a vertically adjustable rod support assembly for selectively supporting a curtain rod and curtain at an elevated height, and for enabling a user to lower the vertical height of the curtain rod in order to attach or detach the curtain from the rod, without the need for standing upon a ladder or another object. The invention is illustrated by example in the drawing figures, and throughout the written description. It should be understood that numerous variations are possible, while adhering to the inventive concept. Such variations are contemplated as being a part of the present invention.
