CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority from U.S. Prov. Pat. App. Ser. No. 61/448,630, filed Mar. 2, 2012, entitled Curtain Rod Assembly, the entire disclosure of which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure
The present disclosure is directed towards the field of curtain rods and more particularly to a wooden curtain rod which can be formulated form a number of different components.
2. Background Art
The use different curtain rods is well known in the art. Typically, curtain rods comprise an elongated member that is extended between two or more supports. A plurality of hooks or other members are slidably positioned on the elongated member. A curtain is coupled to the hooks at discrete location. Thus, the curtain hangs on the hooks that are slidably coupled to the curtain rod.
Typically, the curtain rod comprises a metal member, a plastic member or a wooden member (or combinations of the foregoing). Such curtain rods typically have a substantially consistent cross-sectional configuration along the length thereof. The curtain rods that are formed from moldable materials, or stampable materials may include transverse carvings and shapes therealong. Also, longitudinal carvings and shapes may be disposed along the length of the curtain rod.
Problematically, with wooden curtain rods, it is difficult and costly to provide transverse surface configurations in the form of carvings and shapes. First, lathes are utilized to impart transverse surface configurations onto wooden rods, however, curtain rods are typically substantially longer than the operating length of a lathe. In addition, to maintain integrity of a curtain rod, it is difficult to join a plurality of different wooden portions to assemble a curtain rod of a desired length from the wooden portions. Often bowing, especially about joints, is of large concern.
It is an object of the present disclosure to provide a wooden curtain rod having transverse surface configurations.
It is another object of the present disclosure to provide a curtain rod that has sufficient strength when formed of a plurality of different components.
It is another object of the present disclosure to provide a wooden curtain rod which includes multiple components wherein it is difficult to discern the joints where the different components are coupled together to form the resulting member.
These objects as well as other objects of the present invention will become apparent in light of the present specification, claims, and drawings.

DETAILED DESCRIPTION OF THE DISCLOSURE

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and described herein in detail a specific embodiment with the understanding that the present disclosure is to be considered as an exemplification and is not intended to be limited to the embodiment illustrated.
It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings by like reference characters. In addition, it will be understood that the drawings are merely schematic representations of the invention, and some of the components may have been distorted from actual scale for purposes of pictorial clarity.
Curtain rod assembly 10, as shown in FIG. 1, as comprising an elongated member which includes various designs (surface configurations) which are transversely disposed along the length thereof. These surface configurations provide a uniform appearance that is aesthetically pleasing, and that further hides the nature of the curtain rod as comprising a plurality of joined components. In the embodiment depicted, the curtain rod assembly depicts, or loosely mimics, a bamboo culm, having alternating nodes and internodes transversely disposed along the assembly. In such a configuration, the nodes include a central region of a first diameter and opposing ridge regions of a second diameter, wherein the second diameter is larger than the first diameter. The second diameter is also larger than diameter of the internodes.
It will be understood that the curtain rod assembly 10 is modular in that it is formed from a plurality of elongated units (as will be described) that are joined together end to end. Additionally, it will be understood that the invention is not limited to a bamboo culm that is shown, but that a number of transverse decorative elements are contemplated for use. It will be understood that the disclosure is not limited to any particular configuration of the transverse decorative elements.
With continuing reference to FIGS. 1 and 2, the curtain rod assembly 10 comprises a plurality of separate units that are joined end to end, such as, first end unit 12, a middle unit 14, and a second end unit 16. It is contemplated that each of the units comprises a wood material, such as, for example, a solid pine member. Other woods, such as oak, basswood, maple, among others are contemplated for use. It is additionally contemplated that multiple wood materials may be laminated or bonded together to form a single sold member. It is also contemplated that the member may be cored out to reduce the weight thereof. With reference to FIG. 3, a curtain 100 can be hung from a plurality of hook members 102 that are coupled to the curtain rod assembly 10. Additionally, curtain rod assembly 10 can be coupled to an outside structure, such as a wall with hangers and the like.
The first end unit 12 has an elongated body 20 made from wood with a first end 30, a second end 32, and an outer surface 34. The first end 30 has a face 50 and a first partial mating transverse decorative element 52. The face 50 is circular and flat in configuration. The face 50 is where a connecting rod guide 80 is positioned. The first partial mating transverse decorative element 52 will mate with another partial mating transverse decorative element on a middle unit 14 (described below) forming a transverse decorative element that is substantially indistinguishable from transverse decorative element 52.
The connecting rod guide 80 that is positioned on the face 50 has a plurality of holes 100 on its surface. The holes 100 are where the plurality of rod guide fasteners 110 screw in to attach the connecting rod guide 80 to the face 50 of the first end 30.
The second end 32 of the body 20 has a face 54, which is also flat and circular in configuration. The second end 32 defines one of the ends of the curtain rod. Face 54 remains exposed as it is an end piece. As such, it may be substantially planar. It is contemplated that certain end features are coupled to face 54 to provide a decorative end to the curtain rod (such as a bulb, an acorn or other rounded element 57, FIG. 2). The second end 32 also has a second partial mating transverse decorative element 56. The second partial mating transverse decorative element 56, in this case, does not mate with another partial mating transverse decorative element.
The outer surface 34 of the body 20 has a plurality of central transverse decorative elements 58. In this particular configuration the central transverse decorative elements 58 are in the form of nodes and the space between the nodes are internodes. This gives the curtain rod assembly 10 an overall appearance of a bamboo culm. It will be understood that the curtain rod assembly 10 is not limited to this particular configuration and can take on the form of various transversely disposed designs (both circumferential and designs which define helixes or other structures that are both transverse and longitudinal).
It will be understood that the curtain rod assembly 10 can include a number of middle units 14 to accommodate curtains and windows of various sizes. Each of the middle units 14 can be substantially identical. The disclosure is not limited to any particular number of middle units 14. The middle unit 14 has an elongated body 22 made from wood that has a first end 36, a second end 38, and an outer surface 40. In the embodiment shown, the first end 36 and the second end 38 are substantially identical in configuration. Multiple middle units 14 can be coupled in an end to end configuration.
The first end 36 has a face 60 and a first partial mating transverse decorative element 62. The face 60 is flat and circular in configuration. The first partial mating transverse decorative element 62 mates with another partial mating transverse decorative element on the first end unit 12 or the second end unit 16. If more than one middle unit 14 is involved, the first partial mating transverse decorative element 62 can also mate with another partial mating transverse decorative element on the other middle unit 14.
A connecting rod guide 82 is positioned on the face 60 of the first end 36 of the middle unit 14. The connecting rod guide 82 has a plurality of holes 102 positioned on its surface. A plurality of connecting rod guide fasteners 112 attach the connecting rod guide 82 to the face 60 when they are screwed into the holes 102.
In the embodiment shown, a threaded connecting rod 84, 88 respectively are on each one of the ends of the middle unit 14. When multiple middle units 14 are used, only one end will require the threaded connecting rod, 84 or 88. As shown in FIG. 1, the threaded connecting rod 84 is positioned within the center of the connecting rode guide 82. The threaded connecting rod 84 connects with the connecting rod guide 80 or 90 on either the first end unit 12 or the second end unit 16.
The second end 38 of the body 22 is substantially identical to the first end 36 of the body 22. The second end 38 has a face 64 and a second partial mating transverse decorative element 66. The face 64 is flat and circular in configuration. The second partial mating transverse decorative element 66 mates with another partial mating transverse decorative element on the first end unit 12 or the second end unit 16. If more than one middle unit 14 is involved, the first partial mating transverse decorative element 66 can also mate with another partial mating transverse decorative element on the other middle unit 14.
A connecting rod guide 86 is positioned on the face 64 of the second end 38 of the middle unit 14. The connecting rod guide 86 has a plurality of holes 104 positioned on its surface. A plurality of connecting rod guide fasteners 114 attach the connecting rod guide 86 to the face 64 when they are screwed into the holes 104.
As mentioned earlier, in the embodiment shown, a threaded connecting rod 84, 88 respectively are on each one of the ends of the middle unit 14. When multiple middle units 14 are used only one end will require the threaded connecting rod, 84 or 88. As shown in FIG. 1, the threaded connecting rod 88 is positioned within the center of the connecting rode guide 86. The threaded connecting rod 88 connects with the connecting rod guide 80 or 90 on either the first end unit 12 or the second end unit 16. The positioning of the threaded connecting rod is at the center of the cylindrical configuration of the various units, so that the axis of the threaded connecting rod substantially corresponds to the central axis of the unit. In such an embodiment, the joints between the units have the best chance of mimicking the decorative elements therebetween.
The outer surface 40 of the body 22 has a plurality of central transverse decorative elements 68. In this particular configuration the central transverse decorative elements 68 are in the form of nodes and the space between the nodes are internodes. This gives the curtain rod assembly 10 an overall appearance of a bamboo culm. It will be understood that the curtain rod assembly 10 is not limited to this particular configuration and can take on the form of various transversely disposed designs.
In many embodiments, the first end unit 12 and the second end unit 16 are substantially identical in shape and in configuration. The second end unit 16 has an elongated body 24 made from wood with a first end 42, a second end 44, and an outer surface 46. The first end 42 has a face 70 and a first partial mating transverse decorative element 72. The face 70 is circular and flat in configuration. The face 70 is where a connecting rod guide 90 is positioned. The first partial mating transverse decorative element 72 will mate with another partial mating transverse decorative element on a middle unit 14 forming a uniform look to the overall structure. Thus, even though the curtain rod assembly 10 is not formed from one solid piece of wood it is difficult to discern that it is so formed, much less where the particular joints are positioned.
The connecting rod guide 90 that is positioned on the face 70 has a plurality of holes 106 on its surface. The holes 106 are where the plurality of rod guide fasteners 116 screw in to attach the connecting rod guide 90 to the face 70 of the first end 42.
The second end 44 of the body 24 has a face 74, which is also flat and circular in configuration. The second end 44 defines the opposite end of the curtain rod. While nothing is shown as being attached to face 74, it is contemplated as with the first end of the curtain rod, a finishing element may be coupled to the face or otherwise covering the face. The second end 44 also has a second partial mating transverse decorative element 76. The second partial mating transverse decorative element 76 does not mate with another partial mating transverse decorative element.
The outer surface 46 of the body 24 has a plurality of central transverse decorative elements 78. In this particular configuration the central transverse decorative elements 78 are in the form of nodes and the space between the nodes are internodes. The nodes include a central region and opposing ridge regions which are of larger diameter than either the central region or the internodes. The joint between units mimics the central region of the nodes, and, this reduced diameter further disguises the joint. This gives the curtain rod assembly 10 an overall appearance of a bamboo culm. It will be understood that the curtain rod assembly 10 is not limited to this particular configuration and can take on the form of various transversely disposed designs.
To assemble the curtain rod assembly 10, the first end 30 of the first end unit 12 having the connecting rod guide 80 installed, connects with the first end 36 or the second end 38 of the middle unit 14, depending on which one of the ends has the threaded connecting rod 84 or 88. In the embodiment shown, the connecting rod guide 80 on the first end 30 of the first end unit 12 connects with the threaded connecting rod 84 on the first end 36 of the middle unit 14. The threaded connecting rod 84 screws in to the connecting rod guide 80. At this point the first end unit 12 is connected to the middle unit 14. The connection point forms a node when the first partial mating transverse decorative element 52 of the first end unit 12 meets with the first partial mating transverse decorative element 62 of the middle unit 14.
Next, the second end 38 of the middle unit 14 connects with the first end 42 of the second end unit 16. It will be understood that this is only one particular configuration of the curtain rod assembly 10. The curtain rod assembly 10 has the ability to connect as many middle units 14 together as desired. In that case, each middle unit 14 will only have one end 36 or 38, respectively with a threaded connecting rod, 84 or 88. In the embodiment shown, the threaded connecting rod 88 on the middle unit 14 screws into the connecting rod guide 90 on the second end unit 16. The second partial mating transverse decorative element 66 on the second end 38 of the middle unit 14 meets with the first partial mating transverse decorative element 72 on the first end 42 of the second end unit 16 and forms a node. The node has two rounded edges that are raised with a smaller channel in between. When the middle unit 14 is connected to the second end unit, the curtain rod assembly 10 is now assembled and has the appearance of a bamboo culm with nodes and internodes. It is to be understood that the bamboo culm is only one of the many transverse decorative designs available.
In the embodiment shown, each one of the faces has an area of approximately 1385 mm². Each one of the connecting rod guides has an area of approximately 490 mm². The area of the face surrounding the connecting rod guide is about 894 mm². The connecting rod guides are sunken into the face and the large hole in the center of the connecting rod guides are threaded in order to engage the threaded connecting rod. The threaded connecting rod can be tightly screwed into the connecting rod guide, forming a tight connection. This helps the curtain rod assembly 10 to have a uniform appearance. Specifically, with the connecting rod guides being sunken into the surface, the threads extend beyond the faces and allow continued tightening. Coupled with a substantially large contact area where two abutting faces meet, the two structures insure that there is a strong contact over a substantial surface area that circumscribes the sunken in connecting rod guides. Such a structure minimizes sagging, or bowing, of the resulting curtain rod about the joint.
Finally, the curtain rod assembly 10 appears to be one uniform piece of wood. One cannot tell that the curtain rod assembly 10 is comprised of the first end unit 12, one or a plurality of middle units 14, and a second end unit 16. It will be noted that the curtain rod assembly must include one first end unit 12 and one second end unit 16. The first end unit, the middle unit 14, and the second end unit are all capable of supporting at least fifty pounds, making the curtain rod assembly 10 quite strong. Additionally, the curtain rod does not exhibit sagging, and especially does not exhibit sagging about the joints, thereby providing the appearance of that it is formed from a single unitary piece of material.
The foregoing description merely explains and illustrates the invention and the invention is not limited thereto except insofar as the appended claims are so limited, as those skilled in the art who have the disclosure before them will be able to make modifications without departing from the scope of the invention.
