Abstract
I designed the “Classic Step Store Gate”, It does not use a pivot post. Classic, Step Store Gate uses my special hinge made by modifying a strap hinge. “Classic” is different in design; “Classic” has a rounded firm handrail across the top, and can help prevent a fall at the steps. It is used at steps going up or down. The opening end of the gate is lifted to open toward steps or into the room. The “Classic Step Store Gate”, has an attractive clean look from the front view, and an interesting mechanical view from the back. The gate can be stored along the wall on the steps. When closed the gate rest in “V” tapered brackets to support the end of the gate

Hand hold horizontal beams, are designed and built with a recess for mounting vertical beams flush on the back side;
- drawing #1, Fig. C;
- pointer #3, show a recessed area for #5, rounded top & bottom vertical members to be flush on the back side of the gate. Either beam can be used as a top hand rail as they are the same. Vertical pickets rotate in the recessed area as the gate is lifted. Also see drawing # 2;
- horizontal hand hold beam #3, and vertical pickets #5. Also see drawing #7;
- Fig. H, cross section A-A Vertical beam #1 and hand hold top beam #3
All Vertical beams rounded both ends:
- this provides equal clearance, as the gate is lifted or lowered. The center of pivot point, are the center of radius, therefore end clearances remain equal as gate is lifted or lowered. Screws or pivot pins are installed from the back of the gate through a drilled hole in the vertical beams or pickets:
- see drawing #1, Fig “A” front view;
- drawing #2, Fig. D back view;
- drawing #3 Fig. “A” Side angle view;
- drawing #4, Fig. “A” perspective.
Specially designed gate hinge:
- Drawing #6, Fig G;
- describes the design of the hinge.
- A strap design hinge #2, drawing #6 and #7;
- is bent 90 degrees, one inch from hinge pin. Pointer # 24 hole is drilled slightly larger than the pivot screw # 23. Pivot screw passes through a slightly larger hole drilled through the vertical beam # 1, and then passes through the hinge and a nylon washer and anchors into the horizontal gate handrail pointer #3. The hinge is first secured to the vertical beam #1 with flat head screws through holes #25. Allowing the pivot point pin to pass through the hinge to strengthen the framework, and places the load of the horizontal beams on the steel hinge, causing it to be a solid structural member. Also see drawing # 5;
- Fig. E, F, and G. Holes through #2 hinge, #26;
- are later used to mount the hinge and gate to a door frame or wall.
- Drawing #7;
- Fig. G, gives detail of hinge #2 and pivot pin screw # 23, and nylon washer # 24. Fig H, #2 indicates hinge location and nylon washer, Cross section A-A shows pivot screw 23 passing through vertical member #1, nylon washer between hinge and horizontal beam. Use of the hinge is indicated on drawings as pointer #2:
- Drawing numbers 1, 2, 4, 5, 6 and 7.
