Abstract
A curtain rod support system includes a support member and a mounting plate attachable to a supporting structure with a pair of screws. The mounting plate has a fixed member, and preferably a threaded member extending therefrom and engageable with the support member, virtually eliminating the need for additional, trial and error adjustment of the mounting plate with respect to the supporting structure. The mounting plate is first affixed to the support structure using the pair of screws, the fixed screw of the mounting plate is inserted into a blind bore in the support member, and the support member is rotated until the screw has essentially fully advanced within the bore. The support member has a second bore completely therethrough and through which a curtain rod may be extended so that the support member bears the weight of the curtain rod and suspended draperies. A finial may be attached to the end of the curtain rod for decorative purposes and to further secure the curtain rod within the bore of the support member.
Description




FIELD OF THE INVENTION




The present invention relates to the field of window treatments, and more particularly to curtain rod support systems, and provides a mountable structure for securely and positively engaging and supporting a curtain rod.




BACKGROUND OF THE INVENTION




Although conventional curtain rod support systems appear to be simple and straightforward to use, they can present a number of problems upon installation. Typically, conventional curtain rod support systems include a support member and a companion plate fittable to the support member, many of which have a keyhole opening therethrough that narrows at one end, typically the upper end, for engaging an anchoring apparatus such as a screw or nail such that the support member is suspended from the anchoring apparatus. The companion plate is first attached directly to the support member, usually either as packaged or as a pre-installation step. The anchoring apparatus is then inserted into a supporting structure, such as a wall, at the desired location of the curtain rod support system, and the support member with companion plate attached is mounted onto the anchoring apparatus by inserting the anchoring apparatus into the keyhole opening of the plate and engaging the anchoring apparatus within the narrow portion of the keyhole opening so that the support member is suspended from the anchoring apparatus. Should the anchoring apparatus be mounted too far into the supporting structure, it would be impossible to insert the anchoring apparatus into the keyhole opening of the companion plate, given its depth into the support member. In this case, the anchoring apparatus would have to be withdrawn from the supporting structure to a position where the keyhole opening would be fittable over it and suspendable from it. Furthermore, should the anchoring apparatus be mounted too far out of the supporting structure, the anchoring apparatus would need to be advanced farther into the supporting structure so that the support member would not sag when suspended from the anchoring apparatus. Repeated adjustments of the anchoring apparatus into or out of the supporting structure could cause damage to the surrounding sheetrock, plaster, or other composition of which the supporting structure may be constructed. Additionally, unsuccessful attempts to fit the keyhole opening over the anchoring apparatus could cause marring or chipping of the surrounding paint or other finish of the supporting structure. Moreover, if the anchoring apparatus is not firmly set within the narrow portion of the keyhole opening upon engagement, the support structure may sag or may disengage from the anchoring apparatus altogether. This could cause damage to the finish of the supporting structure and, further, could result in injury to anyone who might be standing near or under the support structure.




Yet another problem with conventional curtain rod support systems such as the previously described system is that the weight of the supported curtain rod and any draperies suspended therefrom results in a pivotal force that is concentrated solely on the singular anchoring apparatus. Over time, this force is likely to extract the anchoring apparatus from the supporting structure to which it is attached and particularly from application of a shortened moment of from a shortened distance from the narrow portion of the key hole to the lower wall touching portion of the support member.




The resulting frustration from a trial-and-error depth placement of the anchoring apparatus, and the possible mis-mounting of the keyhole plate at the rear of the curtain rod support will almost guarantee a sloppy installation, even when the installer is expert.




What is therefore needed is a curtain rod support system which facilitates a simple and easy installation and which minimizes the potential for error and thus the need for repeated adjustments. The needed system should provide adequate curtain rod and drapery support, and should distribute the support force resulting from the weight of the supported rod and any draperies so that the possibility of disengagement of the curtain rod support system from the supporting structure to which it is attached is reasonably mitigated.




SUMMARY OF THE INVENTION




The curtain rod support system of the present invention includes a support member and a mounting plate combination attachable to a supporting structure, such as a wall, using a pair of preferably maximum reasonably spaced apart screws or similar hardware. The mounting plate has a fixed threaded member screw, preferably secured to the mounting plate. The formation of the screw to the plate can be accomplished by welding or by insertion through an aperture in the plate, with preferable finishing to flatness of the rear of the plate which will depend from the wall. This may be accomplished by forming an aperture in the plate and insertion of the threaded screw and affixation by a weld or other similarly strong bond, with the back side of the plate finished as by grinding, for example. The screw will preferably extend perpendicularly away from the mounting plate, and the screw or threaded member is to engage a support member once the mounting plate has been secured to a supporting structure. Likewise, the support member has a first end with a bore therein that will accept the fixed screw of the mounting plate. The bore may be a threaded bore where the screw is a machine screw, or the bore may be an un-threaded or threaded bore where the screw is a wood or relatively soft material engagement screw, especially where the screw forms its own threads as the support member is twisted onto the screw. Because the mounting plate screw is initially fixed, before addition of the supporting structure, the need for any adjustment of the mounting plate with respect to the supporting structure is virtually eliminated. The mounting plate is first affixed to the support structure using the pair of screws so that the plate is coplanar with and contiguous to the adjacent supporting structure. The mounting plate screw is then inserted into the blind bore of the first end of the support member, and the support member is subsequently rotated onto the mounting plate screw until the screw is essentially fully advanced within the bore. The support member has a second end that extends generally away from the first end, and which has a bore completely therethrough and perpendicular to the blind bore of the first end. A curtain rod may be extended through the bore of the second end of the support member so that the support member bears the weight of the curtain rod, finials, and any draperies that may be suspended from the curtain rod. Once the curtain rod is extended through the bore in the second end of the support member, a finial may be attached to the end of the curtain rod for decorative purposes and to further secure the curtain rod within the bore of the second end of the support member. Because the mounting plate is attached to the supporting structure using a pair of screws rather than a single screw, the pivotal force exerted on by the weight of the curtain rod, attached finials, and any suspended draperies is distributed between the two screws, thus diminishing the possibility that the mounting plate and support member will be pulled away from the supporting structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The description and operation of the invention will be best initiated with reference to

FIG. 1

which illustrates from an elevated perspective the curtain rod support system


11


of the present invention in an exploded configuration.

FIG. 1

illustrates a support member


13


having a first end


15


and a second end


17


extending generally away from first end


15


. Note that the support member


13


may be constructed from a variety of materials such as wood, metal, resin, or a composite. Additionally, the support member


13


may be any of a variety of overall designs and shapes. First end


15


has a blind bore


21


therein which is illustrated in phantom and which is generally co-axial with an axis of the support member


13


. Second end


17


has a large bore


23


therethrough having an axis generally perpendicular to the axis of the support member


13


. Large bore


23


is for accepting and supporting a curtain rod


25


. Note that while the bore


23


is illustrated as extending completely through the second end


17


of the support member


13


, another possible embodiment could include a bore


23


extending only partially through the second end


17


of the support member


13


. The curtain rod


25


has a blind bore


27


in its end portion


31


which is illustrated in phantom. The curtain rod support system


11


is shown adjacent an optional finial


33


, having a projection


35


frictionally engageable with the blind bore


27


of the end portion


31


of the curtain rod


25


for decorative purposes and perhaps for securing the curtain rod


25


within the large bore


23


of the second end


17


of the support member


13


, where such special arrangement is made. Note that if the bore


23


extended only partially through the second end


17


of support member


13


, the need for finial


33


would be eliminated. A mounting plate


37


is shown adjacent the first end


15


of support member


13


. Although the overall shape of the mounting plate


37


is illustrated as generally rectangular with curved ends to coincide with the overall shape of the first end


15


of the support member


13


illustrated in

FIG. 1

, note that the mounting plate can occupy any shape that will aesthetically coincides with the shape of the first end


15


of the support member


13


. In one aspect, it is important that the end


15


of any support member


13


either cover or match the extent of the mounting plate


37


. Mounting plate


37


has a fixed threaded member or screw


41


that extends perpendicularly away from the plane of the mounting plate


37


. The fixed screw


41


is preferably secured to the mounting plate


37


with a weld or a similarly strong bond. Where the weld is at the front of the mounting plate


37


, a chamfer may be had at the first end


15


of the support member


13


to accommodate the weld. Additionally, the fixed screw


41


may be a wood screw, a metal screw, or any other screw appropriate for use with the material of which the support member


13


is constructed, or of the fittings had and supported by the support member


13


. Mounting plate


37


has a pair of apertures


43


and which are situated adjacent either side of fixed screw


41


. Also illustrated in

FIG. 1

is a pair of screws


45


adjacent mounting plate


37


. Once the mounting plate


37


has been secured to a supporting structure (not illustrated) using the pair of screws


45


, the support member


13


is joined with the fixed screw


41


of the mounting plate


37


by inserting the fixed screw


41


into the blind bore


21


of the first end


15


of the support member


13


and rotating the support member


13


until the fixed screw


41


has advanced essentially the full length of the blind bore


21


, to the extent possible. The support member


13


may then be rotated such that the axis of the large bore


23


of the second end


17


of the support member


13


makes an angle of either zero or one-hundred eighty degrees with respect to the axis of the curtain rod


25


, especially since the support member


13


has bi-lateral symmetry. This simplest of periodic symmetry is shown to illustrate the other symmetries available. For example, were the mounting plate


37


to be round, the symmetry would be limited by the large bore


23


. If the large bore


23


was a fitting having a pair of crossing bores, the symmetry would be subdivided into ninety degree increments. Any additional symmetry enabling the support member


13


to achieve alignment with a lesser number of turns is encouraged. Other helps can be had as by having the end


15


to be fitted with a deformable material, or even a seal to distribute the support of the end


15


of the support member


13


firmly across the plate


37


.




Using the pair of screws


45


allows the pivotal force resulting from the weight of the curtain rod


25


and any attached finial


33


and drapery to be distributed between the pair screws


45


to give increased stability. This particular distribution of force is preferable to that which occurs using only a single anchoring structure since it aids in preventing disengagement of the curtain rod support system from a supporting structure. Once the curtain rod


25


is extended through the large bore


23


of the second end


17


of the support member


13


and any draperies (not illustrated) have been suspended from the curtain rod


25


, the projection


35


of the finial


33


may be frictionally engaged with the blind bore


27


of the end portion


31


of the curtain rod


25


as a finishing measure and to ensure that the curtain rod


25


stays seated within the large bore


23


of the second end


17


of the support member


13


.





FIG. 2

is a cross-sectional view of the curtain rod support system


11


as mounted to a supporting structure


47


.

FIG. 2

illustrates mounting plate


37


attached to supporting structure


47


with the pair of screws


45


. Support member


13


is shown attached to the fixed screw


41


of mounting plate


37


. The bore


23


in the second end


17


of the support member


13


is illustrated clearly in FIG.


2


.
