| 说明书全文 | TECHNICAL FIELD The invention is related generally to closet rod supports and, in particular, to an adjustable height closet rod support. BACKGROUND OF THE INVENTION Closets in older homes usually are supported by brackets mounted on the closet walls. One such support bracket is disclosed in U.S. Design Pat. No. Des. 319, 573 to Rogers (“Rogers”). Using the support bracket in Rogers involves positioning the closet rod ends inside each of the support brackets. A disadvantage of this configuration is that as more clothing is hung the closet rod may weaken. When weakened, the closet rod may sag. The sagging causes the clothing to move toward the center of gravity. As a result, the clothing can become wrinkled due to lack of sufficient spacing between items. The closet rod may even break. When this happens, all the clothing is spilled onto the closet floor. Cleaned and ironed clothes become soiled and wrinkled. This is particularly troublesome in older homes whose closet rods have lost some of their strength. Alternatively, the brackets may be loosened from the closet walls. When this happens, the closet walls may become damaged. The closet rod leans and the clothes migrate to the new center of gravity on the closet rod, again resulting wrinkling of the clothes due to lack of sufficient spacing. The brackets also may separate completely from the closet walls. This usually results in gaping holes in the walls. Additionally, the clothes fall to the closet floor and become soiled and wrinkled. This is particularly troublesome in homes whose walls are made from sheet rock. What is needed, therefore, is a closet rod support that overcomes these disadvantages. SUMMARY OF THE INVENTION Presented herein is a rod support. One embodiment includes an apparatus with a housing, a spring, an insert, and a cradle. The spring and insert fit into the housing. The cradle is mounted on the insert. The apparatus is placed under a rod to provide vertical support. When the cradle receives the rod, the spring compresses commensurately with the weight of the rod and any items on the rod. The rod supports the weight of the rod and any items on the rod, thereby relieving stress on the rod itself, as well as the walls, brackets, and other hardware used to mount rod. Another embodiment includes a housing, an insert positioned inside the housing, and a rod cradle mounted to the insert. The insert and housing are threaded such that the insert screws into the housing. One feature of the invention is that there is no mounting hardware needed to install the rod support. The advantage of this feature is that the rod support can be installed easily, without tools or fasteners. Another feature of the invention is that it is adjustable to various heights. This is advantageous because closets are not all the same size. For example, in homes with high ceilings and correspondingly high closet rods, the apparatus height can be raised accordingly. The same is true for homes with low or average height ceilings. That is, the apparatus height can be lowered as needed. Thus, the rod support easily fits into most any space, whether within a closet in a home with cathedral ceilings, in a bungalow, a bath house, etc. Another feature of the invention is its light weight. Its light weight adds to its portability. Further features and advantages of the invention as well as the structure and operation of various embodiments are described in detail below.

DETAILED DESCRIPTION OF THE INVENTION Example Environment An adjustable height closet rod support is described herein. In the following description, numerous specific details, relationships, and methods are set forth to provide a full understanding of the invention. One skilled in the relevant art, however, will readily recognize that the invention can be practiced without one or more of the specific details, or with other methods, etc. In other instances, well-known structures or operations are not shown in detail to avoid obscuring the invention. FIG. 1 shows an environment of intended use for the rod support. FIG. 1 illustrates a front view of a closet 100 suitable for implementing an embodiment of the invention. For ease of explanation, the embodiments sometimes are described with respect to a clothes closet. However, it is to be understood that the invention can be implemented in various other environments, such as a bathroom, a laundry room, a beach house, etc. The exemplar closet 100 has a rod 102 . The rod 102 holds suits, dresses, coats, skirts, blouses, shoe bags, sweater racks, pants, etc. A typical closet rod is about six feet long. Of course, the rod 102 does not have to be a closet rod. For example, the rod 102 can be a shower curtain rod, a towel rack, a clothing rack, etc., to accommodate wet towels, bathing suits, etc., as will be readily apparent to a person of ordinary skill in the art. A pair of brackets 104 A and 104 B, respectively, are mounted on a pair of walls 106 A and 106 B, respectively. The rod 102 is positioned horizontally within the closet 100 , with its ends seated within the pair of brackets 104 A and 104 B. In this configuration, the closet 100 houses the suits, dresses, coats, skirts, blouses, shoe bags, sweater racks, pants, etc., that are hung on the rod 102 . Alternatively, towels, bathing suits, etc., are hung on the rod 102 . As more items are hung on the rod 102 , the rod 102 , the brackets 104 A and 104 B, and the walls 106 A and 106 B are stressed and strained because of the weight of the items. Alternatively, the rod 102 is weakened because of age and use. Example Embodiments An exemplar rod support 110 according to the invention minimizes the stress borne by the rod, brackets, and walls. The rod support 110 is placed under the rod 102 to provide vertical support therefor. In one embodiment, the rod support 110 includes a housing 112 , an insert 114 , and a cradle 116 . The housing 112 admits and provides structural support for the component parts of the rod support 110 . The housing 112 typically is about three feet in height. The housing 112 can be a variety of shapes. For example, the housing 112 can be round, square, pentagonal, rectangular, hexagonal, etc. The housing 112 also can be made from a variety of materials. For example, the housing 112 can be steel, aluminum, or other sufficiently strong metal. The insert 114 fits inside the housing 112 such that its movement within the housing 112 is telescopic. In one embodiment, the insert is positioned loosely inside the housing 112 . That is, the insert 114 freely moves in and out of the housing 112 and may even wobble. The insert 114 can be a variety of shapes, e.g., round, square, pentagonal, rectangular, hexagonal, etc. The insert 114 can be a tube or a solid rod. The shape of the insert 114 is limited only by the shape of the housing 112 . For example, the diameter of the insert 114 should be small enough to permit the insert 114 to be positioned inside the housing 112 . It is not necessary that the insert 114 actually mate with the inner walls of the housing 112 . For example, the insert 114 can have a threaded tip that mates with threads inside the housing 112 . Accordingly, the insert 114 can be threaded to fit into the housing 112 for height adjustment. Moreover, the threaded connection can provide added structural support such that the insert 114 stands rigid within the housing 112 . The cradle 116 is mounted to the insert 114 . The cradle 116 provides support for the rod 102 . The cradle 116 holds the rod 102 in place such that the rod 102 is perpendicular to the cradle 116 and the insert 114 . The cradle 116 can be a variety of shapes. The cradle 116 is described in further detail with reference to FIG. 2 . The rod support 110 has an adjustable height, typically from about four feet in height at its shortest to about ten feet in height. To increase the height, simply raise the insert 114 from the housing 112 to the height where the cradle 116 contacts the rod 102 . Several embodiments implementing this feature are described below. One embodiment includes a spring 118 . The spring 118 fits into the housing 112 . The spring 118 can be mounted to the cradle 116 or the insert 118 . According to this embodiment, when the rod 102 rests on the cradle 116 , the spring 118 compresses commensurately with the weight of the rod 102 and any items on the rod 102 . In this embodiment, the rod support 110 typically is about three feet in height when fully compressed. The rod support 110 typically is about six feet in height when the spring 118 is relaxed. Of course, primarily the weight of the rod 102 determines the height of the rod support 110 . The spring 118 can be any commonly available device of suitable length and tension that urges the insert 118 away from the housing 112 in a telescoping manner. Still, another embodiment includes a base 130 . The base 130 is mounted to the housing 112 . The base 130 can be mounted permanently. Alternatively, the base 130 can be removable from the housing 112 . For example, when the base 130 is a plate, the housing 112 can be welded or soldered to the base 130 . Alternatively, the base 130 can have a threaded lip whereby the housing 112 can be threaded to fit into the base 130 for assembly and disassembly. The base 130 enables the rod support 110 to maintain stability under a load. The base 130 can be a plate, a cup, a cap, etc., or any device suitable for maintaining stability. Moreover, the base 130 can be made from metal, rubber, plastic, etc., or any suitable material. FIG. 2 , which shows an exemplar cradle 116 that is U-shaped. FIG. 2 also shows a connector 202 used to mount the cradle 116 to the insert 114 . Of course, the connector 202 is not required for the invention. For example, the cradle 116 can be permanently mounted to the insert. Alternatively, the cradle 116 can be mounted to the housing 112 . Other exemplar cradles are shown in FIG. 3 and FIG. 4 . FIG. 3 shows a cradle 310 that is in the shape of a semicircle. FIG. 4 shows a cradle 410 in the shape of a semirectangle. The adjustable height feature can be implemented as shown in FIG. 5 , which illustrates example protuberances and openings in the rod support 110 . For example, in this embodiment, the insert 114 has one or more protuberances that correspond to one or more openings or recesses in the housing 112 . The protuberances and openings permit the insert 114 to be raised and set into place in the housing 112 according to the positioning of the protuberances and corresponding openings or recesses. FIG. 5 shows an insert 502 with four protuberances 510 A, 510 B, 510 C, and 510 D mating with a housing 504 with four openings 520 A, 520 B, 520 C, and 520 D. As FIG. 5 illustrates, the openings 520 A, 520 B, 520 C, and 520 D are designed such that the protuberances 510 A, 510 B, 510 C, and 510 D are visible on the outside of the housing 112 . The insert 114 is raised and set into place in the housing 112 by placing the protuberances 510 A, 510 B, 510 C, and 510 D into the openings 520 A, 520 B, 520 C, and 520 D, respectively. The protuberances 510 A, 510 B, 510 C, and 510 D are locked into place within the openings 520 A, 520 B, 520 C, and 520 D. All four sets of protuberances 510 A, 510 B, 510 C, and 510 D and openings 520 A, 520 B, 520 C, and 520 D need not be engaged. For example, the sets of protuberances 510 A, 510 B, 510 C, and 510 D and openings 520 A, 520 B, 520 C, and 520 D can be uniformly spaced apart from each other such that when only the first or top set of protuberances 510 A, 510 B, 510 C, and 510 D and openings 520 A, 520 B, 520 C, and 520 D is engaged, the rod support 110 is at its maximum height. When only the first and second sets of protuberances 510 A, 510 B, 510 C, and 510 D and openings 520 A, 520 B, 520 C, and 520 D are engaged, the rod support 110 is shorter than the maximum height. The height can be adjusted according to the number and position of sets of protuberances 510 A, 510 B, 510 C, and 510 D and openings 520 A, 520 B, 520 C, and 520 D being engaged. It follows that when all sets of protuberances and openings are engaged, the rod support 110 is at its minimum height. Although embodiments are described with respect to four sets of sets of protuberances 510 A, 510 B, 510 C, and 510 D and openings 520 A, 520 B, 520 C, and 520 D, the invention is not so limited. For example, the rod support 110 can have any number of protuberances and corresponding openings. FIG. 6 shows an insert 602 with four protuberances 610 A, 610 B, 610 C, and 610 D mating with a housing 604 with four recesses 620 A, 60 B, 620 C, and 620 D. The embodiment in FIG. 6 operates similarly to the embodiment in FIG. 5 . As FIG. 6 illustrates, however, the recesses 620 A, 60 B, 620 C, and 620 D are closed such that the protuberances 610 A, 610 B, 610 C, and 610 D are not visible on the outside of the housing 112 . FIG. 7 illustrates an embodiment where an insert 702 has two or more openings 702 A and 702 B that correspond to two or more openings 704 A and 704 B in a housing 704 . A pin 710 is inserted into the openings 702 A and 702 B and 704 A and 704 B to hold the insert 114 to a particular height. The rod support 110 can be easily manufactured. For example, all protuberances, recesses, and openings can be aligned such that regardless of the implementation all pieces fit together. For example, the protuberances 510 A, 510 B, 510 C, and 510 D can be located in the same place on the rod support 110 as the protuberances 610 A, 610 B, 610 C, and 610 D. Similarly, the openings 520 A, 520 B, 520 C, and 520 D can be located in the same place on the rod support 110 as the recesses 620 A, 620 B, 620 C, and 620 D. The result is that the pieces of these two embodiments are interchangeable. The same is true for the openings 702 A and 702 B and 704 A and 704 B. FIG. 8 illustrates an embodiment where the rod support 110 includes a block 850 . The block 850 is mounted to the housing 112 . The block 850 can be mounted permanently. Alternatively, the block 850 can be removable from the housing 112 . For example, when the block 850 is a plate, the housing 112 can be welded or soldered to the block 850 . Alternatively, the block 850 can have a threaded tip whereby the block 850 can be threaded to fit into the housing 112 for assembly and disassembly. The block 850 provides the rod support 110 with more height flexibility to accommodate various rod 102 positioning and various ceiling heights. The block 850 can be metal, rubber, plastic, etc., or any material suitable for maintaining stability. This embodiment can be used for height adjustment as well. In this embodiment, to increase the height, simply unscrew the block 850 from the housing 112 to the height where the cradle 116 contacts the rod 102 . FIG. 9 illustrates an embodiment of a rod support 110 whose height is adjustable using a handle 910 . The handle 910 operates a well-known winding or ratchet-like device to raise and lower the insert 114 into and out of the housing 112 . Similarly, in the embodiment where the insert 114 has a threaded tip that mates with threads inside the housing 112 , the height of the rod support 110 can be adjusted. For example, to increase the height, simply unscrew the insert 114 from the housing 112 to the height where the cradle 116 contacts the rod 102 . Alternatively, height can be adjusted using a riser that is positioned inside the cradle. FIG. 10 illustrates a riser 1000 suitable for implementing this embodiment. The riser 1000 mates with the cradle 410 and the rod 102 to minimize any gaps between the cradle 410 and the rod 102 created by not being precisely aligned with each other. The riser 1000 also minimizes any slippage between the cradle 410 and the rod 102 . Of course, the riser 1000 is not limited to the shape depicted in FIG. 10 . For example, depending on the shape, the riser 1000 can fit inside the cradle 116 , cradle 310 , or any other shape that permits proper mating to minimizes gaps between the cradle and the rod.
