Abstract
A folding step for cabinet doors has a step member hingedly connected at its lower end to a cabinet door, such as a sink cabinet, and a support leg member which is hinged at its upper end to the underside of the free end of the step member. A magnet strike plate is mounted on the cabinet door and a magnet is mounted at the top end of the step member. Alternatively, hook and loop type fastener elements may be used in place of the magnet and strike plate wherein one element is secured to the door and the mating element secured to the step member. A pull knob is mounted on the outer surface of the support leg. In a stored position, the step member is held in a vertical position against the cabinet door by the magnet engaged on the magnet strike plate or the hook and loop fastener elements and the support leg is parallel to the step member. When the user pulls on the pull knob, the step and support leg members pivot outward from the cabinet door and fold down. In the down or extended position, the step member and support leg members are perpendicular to one another. The folding step is particularly useful for small children in allowing them to reach a sink or counter top.

Description
Background of the Invention
1. Field of the Invention
This invention relates generally to folding steps which are used with counter cabinet structures such as are found in bathrooms and kitchens, and more particularly to a folding step which attaches to the existing door of a counter cabinet.
2. Brief description of the Prior Art
Small children cannot reach the countertop or sink of a standard height kitchen or bathroom cabinet. As a result, they must be lifted by an adult or some other object must be placed in front of the cabinet for the child to stand on. Often, a small child, will attempt to climb atop the countertop or sink in an attempt to get a glass of water or to wash his or her hands, which is hazardous, and often results in serious injury.
Others have attempted to provide step devices associated with cabinets. There are several patents which disclose various retractable step devices.
Ryan, U.S. Pat. No. 4,135,149, Hartridge, U.S. Pat. No. 2,881,040, and Mushta, U.S. Pat. No. 2,555,149 disclose hinged steps which fold up to be stored inside of a cabinet. These devices take up valuable storage space inside the cabinet.
Gaede, U.S. Pat. No. 3,481,429 discloses a folding step which folds compactly to be stored beneath a cabinet and is pulled out in the manner of a drawer. This devices requires extensive modification to the existing cabinet structure.
Harvey, U.S. Pat. No. 2,599,529 discloses a retractable step which is connected to arm members pivotally mounted to the baseboard of a wall beneath a sink. This device is not particularly suited for use in modern bathrooms or kitchens wherein the sink is mounted in a cabinet.
Richards et al, U.S. Pat. No. 3,030,166 discloses a cabinet having a door which unfolds to become a small stepladder. The stepladder in the folded condition is the door itself. This device requires replacing the door of the cabinet with one which is heavier and more expensive
Smith, U.S. Pat. No. 2,633,179 discloses a folding wall seat in the form of a cabinet door adapted to be installed in or on a wall. The leg which supports the seat member forms the door or closure for the cabinet and when folded into its closed position frictionally engages the bottom of the cabinet to hold itself in its closed position. The wall seat in the closed position is the door itself. This device requires extensive modification of the existing cabinet or wall and replacing the door of the cabinet with one which is heavier and more expensive
The present invention is distinguished over the prior art in general, and these patents in particular by a folding step for cabinet doors which has a step member hingedly connected at its lower end to a cabinet door (such as a sink cabinet), and a support leg member which is hinged at its upper end to the underside of the free end of the step member. A magnet strike plate is mounted on the cabinet door and a magnet is mounted at the top end of the step member. Alternatively, hook and loop type fastener elements may be used in place of the magnet and strike plate wherein one element is secured to the door and the mating element secured to the step member. A pull knob is mounted on the outer surface of the support leg. In a stored position, the step member is held in a vertical position against the cabinet door by the magnet engaged on the magnet strike plate or the hook and loop fastener elements and the support leg is parallel to the step member. When the user pulls on the pull knob, the step and support leg members pivot outward from the cabinet door and fold down. In the down or extended position, the step member and support leg members are perpendicular to one another. The folding step is particularly useful for small children in allowing them to reach a sink or counter top.

Description of the Preferred Embodiment
Referring now to the drawings by numerals of reference, there is shown a conventional cabinet C of the type commonly found in kitchens or bathrooms. Cabinet C has side walls 10, a front wall 11 having an opening (not shown), a top wall or counter top 12, and a door 13 hingedly connected to the front wall which covers the opening. The cabinet is normally installed with its back side disposed against the outer surface of a wall of the dwelling.
In accordance with the present invention, a folding step 14 is attached to the front surface of the cabinet door 13. The preferred folding step 14 comprises a flat step member 15, in the form of a single sheet or board, which is hinged to a flat support member or leg 16 by hinges 17 secured to the underside of the step member 15 and the back surface of the leg member 16. The step member 15 and the leg member 16 ar generally square or rectangular in shape. The hinges 17 are spaced from the top or outer edge 15A of the step member a distance substantially equal to the thickness of the leg member 16, such that in the unfolded position (FIG. 4), the step member will overlap the top edge 16A of leg member 16 and be supported substantially flush with the outer surface of the leg member. A pair of magnets 18 are secured to the top surface 15C of the step member 15 in each outer corner. Alternatively, magnets 18 may be secured to the top edge 15A of the step member 15.
Another set of hinges 19 is secured to the top surface of the step member 15 along the inward facing edge 15B. To install the folding step 14 onto the cabinet door 13, the step and leg members 15 and 16 are unfolded to a perpendicular position and the free ends of the hinges 19 are raised vertically. The folding step 14 is placed in front of the cabinet door 13 with the bottom edge 16B of the leg member 16 resting on the floor and the vertical ends of the hinges 19 against the door surface. The location of screw holes is marked on the door surface with a pencil inserted in the hinge holes.
A series of small holes 20 are drilled through the cabinet door at the marked locations (FIG. 5). A back-up block of wood 21 having small starter holes therein at the same spacing as the hinge screw holes is placed against the back side of the cabinet door 13. Screws 22 are then installed through the free vertical ends of the hinges 19 and the door holes 20 and into the back-up block 21. Glue may be applied to the face of the back-up block 21 prior to securing it with screws to further secure the attachment of the step member.
It should be understood that the hinges 19 on the step member 15 could also be simply screwed onto the cabinet door without drilling holes or using a back-up block. However, most commercial cabinet doors are relatively thin, and the procedure of drilling holes and using the back-up block prevents the door from splitting or cracking when the screws are tightened.
The step member 15 is raised vertically and a pencil line is drawn on the cabinet door along the top edge 15A of the step member adjacent the magnets 18 and the step member 15 is then lowered. A pair of magnet strike plates 23 are secured to the cabinet door 13 along the marked line by gluing or small wood screws. A single magnet and strike plate could be used which would be located along the top edge -5A centered between the side edges. A small handle or knob 24 is provided on the front surface of the leg member 16 for moving the folding step 14 between its folded or stored position and its unfolded or useable position.
Alternatively, a hook and loop type fastener elements may be used in place of the magnet and strike plate wherein one one element is secured to the door and the mating element secured to the step member whereby the step and leg members are releasably retained on the door in the folded position by the hook and loop fastener elements.
The front surface of the leg member 16 may be painted or otherwise decorated to blend in with the decor of the cabinet structure. The top surface 15C of the step member 15 may also be provided with a tread member of rubber or abrasive material to reduce the chances of slipping.
As shown in FIG. 3, in the folded or stored position, the step member 15 is raised vertically and is substantially parallel to the front surface of the cabinet door 13. The step member 15 is maintained in the vertical position by the magnets 18 engaged on the magnet strike plates 23. The leg member 16 is suspended vertically by the hinges 17 and resides parallel to the step member 15. In this position, the cabinet door can be operated normally and no storage space is required for the folding step.
Referring now to FIG. 4, when it is desired to use the folding step, the user pulls outwardly on the knob 24 to disengage the magnets 18 from the strike plates 23. The leg member continues on an outward and downward path while the step member 15 pivots downward about the hinge 19. When completely deployed, the step bottom edge 16B of the leg member 16 is resting on the floor surface, and the step member 15 is supported horizontally between the hinges 19 and the top edge 16A of the leg member 16.
While this invention has been described fully and completely with special emphasis upon a preferred embodiment, it should understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described herein.
