fig1 and 2 show in perspective the two ways of configuring the parts of the present invention . in fig1 a free - standing stool is shown , and in fig2 a folding stool which has a supporting member attached to a step or the lowest shelf of a cabinet . the free - standing stool of fig1 as also seen in fig3 , 5 and 9a comprises two essential parts . as best seen in fig3 and 9a , a platform member 10 is supported by an interlocking supporting member 20 , by means of four 1 / 4 inch machine screws 31 , 32 , 33 and 34 . the fastening means could of course be any similar means such as bolts , or could comprise instead two long fasteners extending through the platform member 10 . screw 31 is inserted through hole 11 in platform member 10 and hole 21 in supporting member 20 , screw 32 through holes 12 and 24 , and similarly on the other side , not shown . as best seen in fig8 a , 9b and 9c , supporting member 21 is provided with recesses 25 , 26 and 27 to permit interlocking and enable it to be fastened to a shelf by screws . the folding stool configuration shown in fig2 is shown in more detail in fig6 , 8 and 9c . in this configuration the supporting member 20 has been inverted with respect to platform member 10 , and rotated through ninety degrees . it has been fastened to a shelf 40 , and then screwed to platform member 10 through hole 12 and the corresponding hole on the other side . fig6 and 7 illustrate two versions of this configuration , differing only by the choice of which of holes 21 , 22 , 23 or 24 on supporting member 20 is selected for assembly to platform member 10 . this choice will be determined by the height of shelf 40 from the floor . this reconfiguration is best seen in fig9 a through 9c . the conversion to a folding stool is easily effected by removing the four screws 31 through 34 and separating the members as shown in fig9 a . the supporting member 20 is inverted and its desired position on the base counter shelf marked with a pencil through holes in its outer wall . these holes may be provided in the supporting member at manufacture , but it is preferred to mold indents into the member , which indents are used to located holes drilled just before installation . generally a clearance of 1 / 2 inch between the edge of shelf 40 suffices to permit closing of the cabinet door , but this will be adapted according to the cabinet itself in an obvious manner . when supporting member 20 is screwed to shelf 40 , the one of holes 21 , 22 , 23 or 24 is chosen which best levels platform member 10 with the floor . it has been found that holes about 1 / 2 inch apart will suffice for adequate leveling in the preferred embodiment . each side is fastened with one screw , tightened enough to hold securely but just loose enough to permit pivoting of the members 10 and 20 with respect to each other . fig8 shows the step stool in the closed position . in the preferred embodiment , the members are blowmolded plastic with an average wall thickness of 0 . 08 &# 34 ; to 0 . 10 &# 34 ;. the height of the platform member , which is slightly domed on top for strength , is 8 . 7 inches from the floor . a 3 3 / 4 inch space between the legs on each member provides a convenient handle area for easy lifting of the stool , or pivoting of the platform member when in the second configuration . a rubber foot is securely screwed to the bottom of each leg to help prevent slipping when the stool is in the free - standing form . as seen best in fig6 , 8 and 9b , recesses are provided for easy clearance during the marking , drilling and mounting operations . in the preferred embodiment , screw holes 21 through 24 , and their counterparts on the other side of the supporting member , are contained in a separate insertable molded plastic member provided with an integral plastic flap or &# 34 ; living hinge &# 34 ; for best appearance . the principal use for the folding step stool will be as described , for supporting a child at a convenient height from the floor in front of a base cabinet . it will of course be recognized , however , that the same kind of arrangement will suffice to hold any object away from a first horizontal surface , where there is a second surface present to which the supporting member may be fastened . the essential point of the invention is its re - configurability between the free - standing and the fastened down , but folding , forms of the stool . the invention has been described in detail with particular emphasis on the preferred embodiments thereof , but it should be understood that variations and modifications within the spirit and scope of the invention may occur to those skilled in the art to which the invention pertains .
a stool with two major parts is disclosed . one way of fastening the parts together yields a rigid free - standing stool . in the alternate configuration a folding stool is formed , which can be fastened to the interior of a base cabinet so that the platform part can be pulled out and used by a child .
