[0087] Referring to FIG. 11, in one embodiment, the upper body support 34 has bottom surface 38 and a series of elongated rollers 40A, 40B, and 40C mounted over the bottom surface 38 for enabling the upper body support to roll over a surface such as a cabinet floor. The upper body support has a distal end 82, a proximal end 84 that is hingedly connected with the lower body support, and first and second lateral sides 86A, 86B that extend between the distal and proximal ends 82, 84. In one embodiment, the elongated rollers in the first series 40A extend the majority of the way across the width W of the upper body support 34. The other series 40B and 40C have similar properties. The elongated rollers 40A, 40B, and 40C are an improvement over the caster wheels found in prior art devices because they extend across the majority of the width W of the upper body support for providing greater support as an operator shifts his or her body weight from side to side on the upper body support. In addition, the weight of the operator is more evenly spread out over the upper body support for minimizing denting, marring or damaging a cabinet floor as the elongated rollers roll over the cabinet floor. The elongated rollers provide a dramatic improvement of the Larson '569 patent, which has a single wheel that supports the entire upper body weight of an individual positioned over a cabinet floor.
[0088] In one embodiment, the plumber's creeper may be made using rugged materials including but not limited to metal, wood, rubber, plastic and/or polymers. The wheels and/or or rollers may be made of suitable materials such as rubber, plastic, resin, polyurethane, synthetic, wood or metal, which will provide low friction maneuverability without damaging, marring or other deleterious effect to floors or cabinet floors.
[0089] The plumber's creeper disclosed herein is height adjustable so that it may be readily used inside cabinets having different cabinet floor heights. Moreover, the plumber's creeper enables the top supporting surfaces of the upper and lower body support members to lie in a common plane. The upper body support provides lateral support via the elongated rollers, which minimize the likelihood of damage to the cabinet floor.
[0090] FIG. 12A shows a cabinet 90 having a cabinet floor CF defining a first height H.sub.5 relative to a floor surface FS. The upper body support 34 is inserted into the cabinet so that the elongated rollers 40A, 40B, 40C contact the top surface of the cabinet floor CF. The height of the lower body support 22 is then adjusted so that the top surface 24 of the lower body support lies in the same plane as the top surface 36 of the upper body support 34, and so that the respective top surfaces 24, 36 of the upper and lower body supports are parallel with the floor surface FS and the top surface of the cabinet floor CF. In FIG. 12A, the outer frame 60 of the lower body support is positioned at its lowest height, as shown in FIG. 7A.
[0091] FIG. 12B shows a cabinet 90′ having a higher cabinet base than the cabinet shown in FIG. 12A. In FIG. 12B, the cabinet 90′ has a cabinet floor CF defining a second height H.sub.6 relative to a floor surface FS, whereby the second height H6 is greater than the first height H.sub.5 shown in FIG. 12A. The upper body support 34 is inserted into the cabinet 90′ so that the elongated rollers 40A, 40B, 40C contact the top surface of the cabinet floor CF. The height of the lower body support 22 is then adjusted so that the top surface 24 of the lower body support lies in the same plane as the top surface 36 of the upper body support 34, and so that the respective top surfaces 24, 36 of the upper and lower body supports are parallel with the floor surface FS and the top surface of the cabinet floor CF. In FIG. 12B, the outer frame 60 of the lower body support 22 is positioned at the third height position, as shown in FIG. 7A.
[0092] Thus, comparing FIGS. 12A and 12B, it can be observed that the height adjustable plumber's creeper 20 disclosed herein may be readily used in cabinets having cabinet bases with different heights. In FIG. 12A, the creeper is in a lower height position for accommodating a cabinet 90 having a lower cabinet base. In FIG. 12B, the creeper is in a higher height position for accommodating a cabinet 90′ having a higher cabinet base. In FIG. 12B, the outer frame 60 is at the third height position relative to the inner frame 50. The height adjustment lever 32 is inserted into the aligned holes to hold the outer frame stable relative to the inner frame 50.

The height of the vertical leg support 118 of the foldable leg 116 is then adjusted so that the top major surface of the board 102 extends along an axis A.sub.1 that is parallel with the floor surface FS, and so that the rubber pads are in support with the top surface of the cabinet floor CF. In FIG. 17A, the proximal end 104 of the board 102 and the foldable leg 116 are located outside the cabinet 122. The horizontal component 120 of the foldable leg 116 sits atop of the floor surface FS.
[0108] FIG. 17B shows a cabinet 122′ having a higher cabinet base than the cabinet shown in FIG. 17A. In FIG. 17B, the cabinet 122′ has a cabinet floor CF defining a height H.sub.8 relative to a floor surface FS, whereby the height H.sub.8 is greater than the height H.sub.7 shown in FIG. 17A. The distal end 106 of the board 102 is inserted into the cabinet 122′ so that the rubber pads 130, 132, 134 secured to the bottom major surface of the board 102 contact the top surface of the cabinet floor CF. The height of the vertical support 118 of the foldable leg 116 is adjusted so that the top major surface of the body 102 extends along an axis A.sub.2 that is parallel with the floor surface FS. In one embodiment, the depressible button 126 shown in FIG. 14 is depressed for adjusting the height of the vertical section 118 of the leg so that the board 102 is parallel to the floor surface FS.
[0109] In FIG. 17B, the proximal end 104 of the board 102 and the foldable leg 116 lie outside of the cabinet 122′. The vertical section 118 and the horizontal section 120 of the foldable leg 116 is supported by the floor surface SF.
[0110] Referring to FIGS. 17A and 17B, in one embodiment, the plumber's support 100 includes a head pad 110 secured over the distal end 106 of the board 102 and a foot pad 112 secured over the proximal end 104 of the board 102. In one embodiment, the head pad 110 has a greater thickness than the foot pad 112.
[0111] Referring to FIGS. 18A and 18B, in one embodiment, a height adjustable plumber's support 200 includes an elongated board 202 having a top major surface and a bottom major surface. A cushioning pad 208 is secured over the top major surface of the plywood board 202. A head pad 210 is secured over the top major surface of the board 202 at the distal end 206 of the board 202 and a foot pad 212 is secured over the top major surface of the board 202 and the proximal end 204 of the board 202. A flexible handle 214 is secured to one side of the board 202 for carrying the plumber's support 200. In one embodiment, the head pad 210 and the foot pad 212 have a similar thickness.
[0112] Referring to FIG. 18B, in one embodiment, the plumber's support 200 includes rubber pads 230A, 230B, 232A, 232B, 234A, and 234B that are spaced from one another and secured to the bottom major surface of the board 202. The plumber's support 200 includes a foldable leg 216 that is secured to the proximal end 204 of the board. In one embodiment, the rubber pads 230A, 230B, 232A, 232B, 234A, and 234B extend from the distal end 206 of the board 202 toward a mid-section of the board 202. The rubber pads prevent the underside of the board from scratching or marring the cabinet floor and provide lateral support as a user rolls from side to side inside a cabinet.
[0113] Referring to FIG. 19, in one embodiment, the plumber's support 200 may be utilized to support an individual inside a cabinet 222 having a cabinet floor CF that is elevated relative to a floor surface FS. In one embodiment, the distal end 206 of the board 202 is inserted into the cabinet 222 so that the rubber pads 230, 232 and 234 overlie the top surface of the cabinet floor CF. The foldable leg 116 is located outside the cabinet 222 for supporting the proximal end 204 of the board 202 over the floor surface FS. The vertical section 118 of the leg 116 is adjusted to a length so that the board 202 extends along an axis A.sub.3 that is parallel with the floor surface FS. The cushion padding 208, the head pad 210 and the foot pad 212 provide cushioning support for a user lying over the top of the plumber's support 200.
[0114] In certain instances, a cabinet may not have a cabinet floor that is higher than a floor surface. In these instances, the position of the head pad 310 and the foot pad 312 may be swapped. In FIGS. 20A and 20B, the head pad 310, which is thicker than the foot pad 312, has been detached from the distal end 306 of the board 302 and reattached at the proximal end 304 of the board 302. As a result, the head pad 310 is positioned over the foldable leg 316 located at the proximal end 304 of the board 302.
[0115] Referring to FIG. 20B, the cabinet 322 does not have a cabinet floor that lies above the floor surface FS. As a result, the lower end of the foldable leg 316 is positioned directly atop the floor surface FS. The thicker head pad 310 is secured over the top major surface of the board 102 at the proximal end 304 of the board 302. The foot pad 312 is secured over the top major surface of the board 302 at the distal end 306 of the board 302.
[0116] Although the present invention is not limited by any particular theory of operation, it is believed that providing a plumber's support 300 having interchangeable head support pads 310 and foot support pads 312 provides a support having more versatility.
