DETAILED DESCRIPTION OF THE INVENTION
Briefly, embodiments of the present invention include a magnetic hanger for hanging textiles having a rod pocket attached to the back surface thereof, and a method for use thereof. In one embodiment, the hanger may include a non-magnetic center tube, two rods which adjustably fit into the center tube, at least one permanent magnet disposed inside the center tube at its center, and a bracket adapted for mounting on a wall or other surface and fabricated from magnetic material. The bracket is effective for attaching to the center tube in the region of the magnet when the center tube is disposed within the rod pocket.
In another embodiment of the invention, the hanger may include a center tube, two hollow, non-magnetic tubes which adjustably fit into the center tube, at least one permanent magnet disposed inside each of the non-magnetic tubes, and at least two brackets adapted for mounting on a wall and fabricated from magnetic material. The at least two brackets are effective for attaching to the non-magnetic tubes in the region of the magnet when the center tube and inserted adjustable tubes are disposed within the rod pocket.
In what follows, the word textile includes fabrics, cloth and quilts.
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. In the Figures, similar or identical structure will be identified using the same reference characters. Turning now to FIG. 1A a schematic representation of a side view of an embodiment of half-pipe bracket, 10, fabricated from magnetic material, such as steel, and having two opposing mounting tabs, 12a and 12b, which may be cut and bent outward from half-cylindrical center portion, 14, is shown. Mounting tabs 12a and 12b have holes 16a, and 16b, respectively, for receiving appropriate wall mounting hardware, such as screws and nails, as examples. It should be mentioned that tabs 12a and 12b may be formed in other ways, for example, by welding such tabs to the back portion of center portion 14.
FIG. 1B is a schematic representation of a side view of an embodiment of a half-pipe bracket having single mounting tab 12a with hole 16a, which tab may be formed in a similar manner to those illustrated in FIG. 1A. FIG. 1C is a schematic representation of a perspective view of the embodiment of the half-pipe bracket shown in FIG. 1B, hereof.
FIG. 2 is a schematic representation of a perspective view of diametrically magnetized solid cylindrical magnet, 18. Permanent magnet 18 may be a rare-earth magnet, such as a neodymium or samarium-cobalt magnets which are substantially more powerful than Alnico or strontium-ferrite magnets. Although FIG. 2 shows a tubular magnet, hollow cylindrical magnets may be employed. Axially magnetized permanent magnets may also be used. In situations where greater magnetic coupling between the permanent magnet and the bracket is needed, multiple magnets and a larger length bracket may be employed.
FIG. 3 is a schematic representation of a side view of a portion of the hanger apparatus hereof, illustrating tubular center rod, 20, having an inner diameter suitable for receiving cylindrical magnet 18. Magnet 18 is affixed an equal distance from either end of hollow center rod 20, and may be press fit, glued or crimp fit, 22, therein. Center rod 20 is constructed of non-magnetic materials for this application. Adjustable rods, 24, and 26, adapted for slidably and adjustably fitting into center rod 20 in order to choose the total length of center rod/adjustable rod assembly, 28, suitable for the length of the rod pocket of a fabric to be hung. As will be shown hereinbelow, end caps or plugs, 30a, and 30b, for locking rods 24 and 26, respectively, assist in keeping assembly 28 centered in the rod pocket of the fabric. Such caps also cover any sharp edges and provide a clean appearance to the adjustable rods. Rotary expansion locking members, 32a, and 32b, may be employed to lock adjustable rods 24 and 26 in a chosen location within center rod 20, respectively, and provide additional support for assembly 28. One known embodiment of such expansion members may include cam-lock devices which expand when the adjustable rod to which an expansion member is attached is rotated relative thereto. Center rod 20 and adjustable rods 24 and 26 may be fabricated from non-magnetic materials such as aluminum or other non-ferrous metal, or from plastic, as examples. Rods 24 and 26 may be hollow rods.
In another embodiment of the invention, hanger 10 may be fabricated from magnetic material which may be permanently magnetized, and center rod 20 from a magnetic material, or a magnetic material insert may be disposed in the center thereof in the location of permanent magnet 18.
FIG. 4A is a schematic representation a portion of the back of a quilt showing the tubular center member 20 shown in FIG. 3 hereof inserted into the rod pocket, 34, of quilt 36, or other textile to be hung. Adjustable rods 24 and 26 have diameters chosen such that a slidable, but snug fit inside of center member 20 is achieved. Lengths are selected in order to enable end caps 30a and 30b of adjustable rods 24 and 26 to extend beyond rod pocket 34 of quilt 38. Half-pipe bracket 10 shown in FIG. 1C is illustrated as magnetically coupled to the magnet disposed inside of center rod 20.
FIG. 4B shows a portion of one end of the back of quilt 36 illustrating cap 30b on the end of adjustable locking tube 26 extending beyond rod pocket 34 of the quilt.
As an example of the use of an embodiment of the magnetic quilt or textile hanger hereof, a location on a wall or other surface is selected, and the mounting bracket is attached to this surface using a nail, hook or other mounting fixture; the middle of the center tube is aligned with the center of the quilt, and the adjustable rods are adjusted and locked such that the end caps are on the outside of the rod pocket an equal distance on each side; and the middle of the center tube is attached to the bracket over the rod pocket. Alternatively, the bracket may be attached to the center tube in the region of the insert magnet over the rod pocket, and the entire assembly of the quilt and the supporting structure hung on the nail or hook, or other mounting fixture. The quilt is self-leveling, and only one hook or nail is generally required.
The center of the quilt or other textile may be found by folding the textile in half with the rod pocket or sleeve on the outside. A paper clip, or some other removable, non-marking device may be used to mark the center. The textile is then placed on a flat surface with the sleeve side facing upward. The center of the center tube of the present apparatus having already been marked is aligned with the paper clip, and the adjustable rods extended or retracted such that the end caps thereof are aligned with the outer edges of the sleeve. The hanging apparatus is inserted into the sleeve with the end caps aligned with the edges of the sleeve, and the textile may be hung on a wall or other location as described hereinabove.
For heavy textiles, it may be necessary to use more than one permanent magnet/bracket combination. In such situations, additional magnets may be placed in the center rod or in the adjustable rods. FIG. 4C illustrates permanent magnet 18 being placed in hollow adjustable rod 26 outside of center tube 20, with bracket 10 attached thereto, and a corresponding magnet/bracket combination would be attached to the second adjustable rod (not shown in FIG. 4C). A permanent magnet mounted inside of center tube 20 may also be used, thereby bringing the number of magnet/bracket combinations to three. Although bracket 10 has been demonstrated to firmly attach to permanent magnet 18, through center tube 20 and rod pocket 34, certain rod pockets are not continuous. In such situations, bracket 10 may be attached to magnet 18 through center tube 20 only.
The foregoing description of the invention has been presented for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application to thereby enable others skilled in the art to best utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims appended hereto.
