the invention is comprised of an upper clamp 101 , a bottom clamp 110 , and an insert 103 . as in fig5 through 8 , the upper clamp 101 is a solid piece of plastic material with a grasping opening 104 , an attachment opening 105 , a body 106 , and two attachment holes 107 . the upper clamp 101 is designed to be attached to the shaft of a cane or crutch . the upper clamp 101 attaches to a cane or crutch shaft by means of wrapping the attachment opening 105 around the shaft and passing a standard screw 116 through the two attachment holes 107 and tightening a standard wing 115 nut on the end of the screw . the flexible attachment opening 104 is made to grip the shaft by means of screw pressure . as in fig1 through 4 , the lower clamp 110 is a solid piece of plastic material with a bottle support 111 , an attachment opening 112 , a body 113 , and two attachment holes 114 . the lower clamp 110 is designed to be attached to the shaft of a cane or crutch . the lower clamp 110 attaches to a cane or crutch shaft by means of wrapping the attachment opening 112 around the shaft and passing a standard screw 116 through the two attachment holes 114 and tightening a standard wing nut 115 on the end of the screw . the flexible attachment opening 112 is made to grip the shaft by means of screw pressure . the invention is used by positioning the upper clamp 101 and lower clamp 110 along the shaft of a cane or crutch in such a manner that an industry - standard 500 ml water bottle can he held between them . the bottom of the bottle will rest inside the circular bottle support 111 and the neck of the water bottle will be held by the grasping opening 104 by means of friction on the neck of the bottle as it is inserted into the grasping opening 104 . because cane shafts can be approximately 1 / 16 ″ thicker than crutch shafts , the invention also includes a thin , 1 / 16 ″ sheet of plastic to use as an insert 103 around a crutch shaft , so that the upper clamp attachment opening 105 and the lower clamp attachment opening 112 will grip the shaft more tightly . a typical insert is shown in fig9 and 10 . in the preferred embodiment , the plastic material comprising the upper 101 and lower clamps 110 is polyurethane . the insert 103 is a flexible , clear plastic . while the foregoing describes a preferred mode and an alternate embodiment , variation on this design and equivalent methods may be resorted to in the scope and spirit of the claimed invention .
a storage device to be attached to a crane or crutch is presented . the storage device is specifically designed to hold a water bottle along the shaft of crane or crutch such that it is easily accessed and securely fastened .
