referring to fig1 , it will there be seen that the reference numeral 10 denotes an illustrative environment of the present invention as a whole . environment 10 includes a kitchen counter 12 having countertop 14 and doors 16 that provide access to space inside side said kitchen counter 12 . cupboards 18 are mounted above kitchen counter 12 and include doors 20 providing access to shelving , not shown , therewithin . the undepicted shelves within said cupboards 18 are hard to reach by people of average height and the uppermost shelves therein are reachable only by a small percentage of the population . fig1 - 3 provide an overview of the novel step so that its general operation may be understood . fig4 - 9 provide views of structural details not readily ascertainable from said fig1 - 3 . the novel step assembly of this invention is depicted in its stored configuration in fig1 and is denoted as a whole by the reference numeral 22 . the height of novel step assembly 22 , when in its stored configuration , is less than the height of overhang vertical wall 23 ( fig1 ) of kitchen counter 12 and the depth of novel step assembly , when in its stored configuration , is slightly less than or substantially equal to the depth of overhang horizontal wall 25 ( fig2 ). accordingly , a person walking pass kitchen counter 12 will not trip over novel step 2 when it is in its fig1 , fully stored configuration . fig2 provides a perspective view of the same environment when novel step 22 assembly is fully extended but not in its operable or deployed configuration . back wall 24 thereof is fixedly secured to overhang vertical wall 23 . openings 24 a , 24 b ( fig5 ) are formed in opposite ends of back wall 24 to receive suitable fasteners . fig3 depicts novel step assembly 22 when in its fully deployed , ready - to - use configuration . front wall 26 is locked into a safe , horizontal position so that a person desiring to reach the uppermost shelves of cupboard 18 may step upon it . a non - skid pad 27 may be placed in overlying relation to front wall 26 to inhibit slipping from said front wall 26 when it functions as a step . some important structural details of novel step assembly 22 are depicted in fig4 . first rear clevis 28 a is fixedly secured to back wall 24 . first rear clevis pin 30 a engages the rearward end of first back rod 32 a and allows said first back rod to pivot in a horizontal plane with respect to a vertical axis defined by first rear clevis pin 30 a . the fully extended configuration of front wall 26 is depicted in phantom lines in fig4 , and its fully deployed configuration is depicted in solid lines in said fig . first forward clevis 34 a is fixedly secured to the rearward side of front wall 26 . first forward clevis pin 36 a engages the forward end of first front rod 38 a and allows said first front rod to pivot with respect to the axis defined by first forward clevis pin 36 a . as depicted in fig5 , a second rear clevis 28 b is fixedly secured to an opposite end of back wall 24 , in laterally spaced apart relation to first rear clevis 28 a . second rear clevis pin 30 b engages the rearward end of second back rod 32 b and allows said rod to pivot in a horizontal plane with respect to a vertical axis defined by second rear clevis pin 30 b . similarly , as suggested by fig4 and 6 and as depicted in fig7 - 9 , second forward clevis 34 b is fixedly secured to the rearward side of front wall 26 . second forward clevis pin 34 b engages the forward end of second front rod 38 b and allows said second front rod to pivot with respect to the axis defined by second forward clevis pin 34 b . first and second back rods 32 a , 32 b have respective forward ends pivotally connected to the rearward ends of first and second front rods 38 a , 38 b about vertical axes 40 a and 40 b . these pivotal connections enable said back rods and front rods to fold with respect to one another in a horizontal plane as best understood in connection with fig7 - 9 . the respective forward ends of first and second back rods 32 a , 32 b are also pivotally connected to the rearward ends of first and second front rods 38 a , 38 b about horizontal axes 42 a and 42 b , said axes being defined by screws or other suitable pins as depicted . these pivotal connections enable said back rods and front rods to fold with respect to one another in a vertical plane as best understood in connection with fig4 and 6 . more particularly , first horizontal pivot block 44 a is pivotally secured to the forward end of first back rod 32 a and second horizontal pivot block 44 b is pivotally secured to the forward end of second back rod 32 b . first vertical pivot block 46 a is fixedly secured to the rearward end of first front rod 38 a by a pair of fastening members collectively denoted 48 a and said first vertical pivot block 46 a is pivotally connected by pivot pin 42 a to first horizontal pivot block 44 a . first flared part 47 a is formed integrally with first vertical pivot block 46 a . second vertical pivot block 46 b is fixedly secured to the rearward end of second front rod 38 b by a pair of fastening members collectively denoted 48 b and said second vertical pivot block 46 b is pivotally connected by pivot pin 42 b to second horizontal pivot block 44 b . second flared part 47 b is formed integrally with second vertical pivot block 46 b . making reference to fig7 - 9 , operation of the novel step includes lightly kicking front wall 26 to cause release springs 29 a , 29 b to push said front wall 26 away from stationary back wall 24 . springs 29 a , 29 b , cause first back and front rods 32 a , 38 a to begin unfolding , as perhaps best understood in connection with fig8 , until they reach their fig9 position . simultaneously , springs 29 a , 29 b , cause second back and front rods 32 b , 38 b to begin unfolding , as perhaps best understood in connection with fig8 , until they reach their fig9 position . springs 29 a , 29 b are also depicted in fig4 - 6 . each spring has a base part that abuttingly engages back wall 24 , a central part that coils about its associated clevis pin 30 a , 30 b , a horizontally disposed top part that overlies its associated back rod 32 a or 32 b , and a vertically disposed side part that abuttingly engages an inboard side of its associated back rod 32 a or 32 b . fig5 , as mentioned above , provides a perspective view of the novel step assembly when in its fully extended ( fig9 ) position . making reference to both fig5 and 9 , front wall 46 is manually lifted from its fig5 and fig9 position into its fig6 position . first and second front rods 38 a , 38 b pivot about horizontal pivot pins 42 a , 42 b until said first and second front rods are vertically disposed with respect to the kitchen floor , i . e ., until said first and second rods are perpendicular to first and second back rods . first and second flared parts 47 a , 47 b of vertical pivot blocks 46 a , 46 b , respectively , provide an enhanced stability of the assembly as best understood in connection with fig6 . it will thus be seen that the objects set forth above , and those made apparent from the foregoing description , are efficiently attained . since certain changes may be made in the above construction without departing from the scope of the invention , it is intended that all matters contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense . it is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described , and all statements of the scope of the invention that , as a matter of language , might be said to fall therebetween .
a step assembly is stored in the overhang area of a kitchen counter when not in use . the step assembly is deployed into an extended position by kicking a vertically disposed front wall . springs then cause a linkage to deploy that positions the vertical front wall away from the front of the counter . the front wall is then pivoted into a horizontal plane where it provides a step that enable a user to reach cupboards mounted above the kitchen counter .
