in one embodiment , the cane holder 10 is generally planar in design , extending inwardly from the support members 25 , 25 to the top or innermost end of the first and second horizontal perpendicular plates 20 , 30 . these plates are referred to as ‘ perpendicular ’ plates 20 , for the purpose of describing the invention because , considering the edge of a mattress as extending along an xy axis , the plates 20 , 30 are perpendicular to that axis . likewise , the plates 20 , 30 are referred to as ‘ horizontal ’ plates 20 , 30 because , considering the top of a mattress as a plane , the plates 20 , 30 extend horizontal to that plane . in some embodiments , each horizontal perpendicular plate 20 , 30 has an outer edge 21 , 31 , inner edge 22 , 32 , upper surface 23 , 33 , and lower surface 24 , 34 . further , the plates 20 , have at least one raised portion positioned 28 , 38 on the upper surface 23 , 33 towards the mattress edge portion of the plates 20 , 30 . however , it is understood that such a configuration is non - limiting ; that is , the one or more raised portions 28 , 38 can be positioned , for example , on the lower surface 24 , 34 of the plates 20 , 30 toward the center of the plate 20 , 30 or elsewhere as desired . in other embodiments , considering the xy axis of the edge of a mattress , a pair of horizontal , parallel plates 40 , 50 run ‘ parallel ’ to this axis in a plane ‘ horizontal ’ to the top plane of a mattress . each horizontal parallel plate 40 , 50 has an outer edge 41 , 51 , inner edge 42 , 52 , upper surface 43 , 53 , and lower surface 44 , 54 . when secured to the horizontal perpendicular plates 20 , 30 , the combination of the horizontal perpendicular plates 20 , 30 and the horizontal parallel plates 40 , 50 prevent the support members 27 , 37 from shifting when the holder 10 is placed between mattresses , thereby insuring that the cane remains secure when stored on the holder 10 . further , the plates 40 , 50 have a recess 46 , 56 centrally located on the lower surface 44 , 54 extending at least partially along the length of the horizontal parallel plates 40 , 50 from both ends . in an embodiment , centered above the recess 46 , 56 are one or more ports 45 , 55 . the ports 45 , 55 are adapted to receive a securing member 60 such as a nut and bolt . the horizontal perpendicular plates 20 , 30 further contain one or more ports 25 , 35 for also receiving the securing member 60 , thereby securing the horizontal perpendicular plates 20 , 30 to the horizontal parallel plates 40 , 50 . the port 25 , 35 can have a recess 29 , 39 for receiving at least a portion of the securing member 60 ( e . g ., the nut ), thereby providing a locking mechanism . the horizontal parallel plates 20 , 30 have multiple ports 25 , 35 spaced equidistant from one another from each end of the plates 20 , 30 . this multitude of ports 25 , 35 enables the spacing of the horizontal perpendicular plates 20 , 30 to be varied from each other , thereby enabling the distance between the support members 27 , 37 to be adjusted as needed based on the length of the cane . in another embodiment , the recesses 25 , 35 can be configured to mate with a portion of the horizontal perpendicular plates 20 , 30 in a ‘ snap - on ’ securing configuration . further , though the horizontal parallel plates 40 , 50 are described such that their lower surface 44 , 54 are adjacent to the upper surfaces 22 , 32 of the horizontal perpendicular plates 20 , 30 when secured together , one skilled in the art would readily recognize that the opposite configuration is also possible , namely , the upper surfaces 43 , 53 of the horizontal parallel plates 40 , 50 can be adjacent to the lower surfaces 24 , 34 of the horizontal perpendicular plates 20 , 30 when secured together , with the recesses 46 , 56 located on the upper surfaces 43 , 53 of the horizontal parallel plates 40 , 50 . because , in some embodiments , the horizontal parallel plates 40 , 50 may be raised above ( or alternatively , below ) the horizontal perpendicular plates 20 , 30 when secured together , slippage of the holder between the mattress and box spring is minimized . still , the holder can be further modified to prevent slippage by , for example , adding a plurality of raised areas 28 , 38 along either the horizontal perpendicular plate 20 , 30 , horizontal parallel plates 40 , 50 , or both . these raised areas 28 , 38 can be located on the upper surfaces 23 , 33 , 43 , 53 , lower surfaces 24 , 34 , 44 , 54 , or both . in yet another embodiment , extending outwardly from one end of the horizontal perpendicular plate 20 , 30 may be a u - shaped support member 27 , 37 for carrying or supporting the cane when the individual is at rest in the best . when in use , the holder 10 with the horizontal perpendicular plates 20 , 30 secured to the horizontal parallel plates 40 , 50 may be inserted between a mattress and box spring until the u - shaped support members 27 , 37 abuts against the mattress or box spring . the holder 10 is inserted with the upper surfaces 23 , 33 , 43 , 53 adjacent to the mattress and the lower surfaces 24 , 34 , 44 , 54 adjacent to the box spring . the cane can then be placed in the support members 27 , 37 such that the handle of the cane is close to a person lying or sitting in bed . the cane holder 10 can be placed between the mattress and box spring in a position where a person in bed can conveniently and confidently access the cane when needed to leave the bed . in an alternative embodiment , the holder may comprise a substantially rectangular horizontal plate having a linear groove extending substantially along an outer edge of the plate . support members separate from the plate having a c - shaped portion at the inner side of the u - shaped support member can then be snapped onto the horizontal plate in a locking fashion into the groove . in this manner , the u - shaped support members 27 , 37 can then be slid along the groove , thereby spacing the members apart from each other based on the length of the cane . the holder can be designed from a variety of materials . because the holder has potential for use in a hospital environment , in an embodiment , the holder is injection molded using a polymeric material suitable for use in a clean or sterile environment . the polymeric material should be sufficiently flexible to bend in use when the weight of a person on the mattress is applied to the holder , yet stiff enough to support the cane . suitable polymers include polypropylene , polyamides , polycarbonate , polysulfone , styrenics and polyesters . preferably , the polymeric material is at least a polycarbonate . polycarbonates are known to have clarity , high strength and impact resistance , good heat resistance , low water absorption and biocompatibility , making them useful in medical devices . in another embodiment , the polymeric material is a combination or blend of various polymers , such as a polycarbonate / acrylonitrile - butadiene - styrene ( abs ) blend or a polycarbonate / polyester blend . because the holder may be utilized by home consumers ; additives can be added to the polymeric material to further differentiate the product . one such additive is color . color technologies in this regard include chroma - shift , metallic , edge glow and glow - in - the - dark . in an embodiment , at least the support members of the holder contain a light emitting additive , preferably a phosphorescent pigment . by addition of a glow - in - the - dark pigment , an individual can more easily locate the cane at night . further , phosphorescent pigment comes in a variety of colors , thereby allowing for greater product differentiation . a further additive for inclusion in the polymeric material is a biocide or antimicrobial additive . choice of biocide is dependent upon a variety of factors , such as cost of the biocide used , the type of polymeric material it is added to , and the environment that it will be exposed to . various types of biocides useful in polymeric materials include , for example , silver - based biocides , organic - based biocides such as triclosan , and silane - based biocides . as the holder 1 has healthcare applications , the polymeric material preferably includes a biocide . in some embodiments , the resin to be used is polycarbonate . the color is provided by techmer polymer modifiers ( techmer pm ) and is identified as pcm6437 . this colorant is specially formulated to match the selected polycarbonate resin base . the present invention is well adapted to attain the ends and advantages mentioned as well as those that are inherent therein . the particular embodiments disclosed above are illustrative only , as the present invention may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teaching herein . furthermore , no limitations are intended to the details of construction or design herein shown , other than as described in the claims below . it is therefore evident that the particular illustrative embodiments disclosed above may be altered or modified and all such variations are considered within the scope and spirit of the present invention . also , the terms in the claims have their plain , ordinary meaning unless otherwise explicitly and clearly defined by the patentee .
