Abstract: A collapsible fire escape ladder. A plurality of folding ladder sections are retained in the folded position by a retractable ladder retention means that slidably engages retention posts fixedly attached to the respective ladder sections. A pivotally mounted ladder entry step is attached to the proximal end of the ladder retention means to facilitate emergency escape through a window or the like. In an alternative embodiment of the ladder, the ladder retention means includes an exit platform having an exit portal disposed when said ladder retention means is retracted above the rungs of the ladder sections.

Abstract: Exercise apparatus having upper and lower elongated members connected end to end by a pivot joint and arranged to be mounted at a wall. Various arrangements of the two members are possible by devices for releasable locking the two members at the wall. In one arrangement both members are secured in a vertical plane against the wall. In other arrangements, either the upper member is pivoted away from the wall and held in a plane parallel to the floor by support at one end by the lower member and at the other end by a fixed pedestal, or both members are pivoted away from the wall, at least the upper end of the upper member being supported by the pedestal at its upper end.

Abstract: An escape device in accordance with the present invention includes an escape opening through the outside wall of a building at second and higher floor level, such opening being tall enough to allow a person to walk through it. A ladder, comprised of at least two sections, is pivoted to structure in the opening and is extendable to reach ground level outside the building. The ladder is stowed in the escape opening and ready for instant use in an emergency.

Abstract: A ladder includes a pair of spaced apart rails having upper and lower ends, and a plurality of substantially identical slats located between the rails. Each slat has a support axle or the like engaging the rails, and defining an axis of rotation for the slat. An actuating bar or rod is operatively connected to each of the slats for selectively and simultaneously rotating the slats from a closed position wherein the slats are substantially coplanar and parallel to the rails, to an open position wherein the slats are oriented transversely to the rails and thus form steps. The actuating bar or the like is restrained in the normally closed position. A trigger mechanism is located at the upper end of the rails and operatively connected to the actuating bar, for selectively releasing the restraining member, whereby the slats can rotate to the open position for use.

Abstract: An exercise apparatus comprises a plane formed by two elongated parts include a pivotal joint arrangement for accomplishing an angle between the parts of the lane. The plane of two parts comprises at the lower part thereof a stationary joint arrangement, which is arranged to be fixed substantially above the horizontal base. Locking devices are provided for locking the plane of two parts into erected vertical position. Adjustable supports are provided for supporting the plane of two parts to form an inclined plane between the stationary joint arrangement of the plane of two parts and the base and for supporting the plane to form an angular plane. The angular plane includes the first elongated part between the stationary joint arrangement and the joint arrangement of the plane of two parts in substantially horizontal position and the second elongated part between the joint arrangement of the plane and the base in substantially vertical position.

Abstract: A collapsible step ladder assembly in combination with a panel of a vehicle such as a tail gate or bed of a pickup truck, having a foldable frame, at least one foldable step or platform, a pair of extension legs, and a pair of articulating joints for connecting said frame to the panel. Each foldable step comprises a platform connected to the respective arms, and a pair of leveling braces that are positioned and dimensioned to hold the platform in a substantially horizontal position when the step ladder is fully deployed between an upper and lower service. Said braces also allow the folding of the platform to a position substantially co-planar with the respective arms.

Abstract: Contractible and extensible ladder of the lazy-tong type for attachment to the underside of a swim/dive platform of a boat or to a deck of a boat. The ladder and the swim/dive platform or deck include coacting means so constructed for positioning the ladder in the contracted position under the swim/dive platform or deck for stowage thereof.

Abstract: A fire escape ladder system for high-rise buildings having balconies with parapets. Each balcony stores its own corresponding ladders. A first ladder is securely mounted on the parapet. This ladder folds out and over the parapet when in use. A second ladder with a flanged top is pushed through a cooperating opening at the base of the parapet. The flange prevents the ladder from sliding through the opening. This second ladder descends to the top of the next lower balcony where it is secured with a bar and clamp assembly. Each user wears a safety belt that connects to T-shaped longitudinal slots integrally formed in both side pieces of the ladder. The ladder systems provide escape routes from balcony to balcony to ground.

Abstract: A folding ladder entirely contained within a U-shaped channel is mounted in a sailboat mast and can be folded and stowed in a flush position, avoiding protruding surfaces on the circumference of the mast. A sliding bar is contained within the U-shaped channel containing a plurality of bracket protrusions which support a swivel pin which in turn support a brace bar connected to a foot bar. One end of the foot bar is fixed to the wall of the U-shaped channel. When the slide bar is moved downward the movement of the brace bar attached to the bracket protrusions extends each step bar forming a series of triangularly supported ladder steps.

Abstract: A folding stairway interconnected with a basement window and its lock, for unlocking the window and opening the window when the stairs are pivoted from a closed or folded position to a down, usable position.

Abstract: This invention consists primarily of a rectangular frame having adapters for securing it to the rear of a camper. The device includes a pair of steps, which fold flat when not in use, and are provided with link rods, for enabling them to fold and open, and the device further includes guide channels and stops for the lower step portion.

Abstract: A hinge for a foldable boat ladder which permits the ladder to be stowed in its folded position without the need for additional fastening means. The hinge comprises a pair of sockets each having a plurality of leaves, the leaves interfitting. The leaves for the upper portion of the ladder have aligned holes carrying a stationary hinge pin. The leaves on the lower socket have inclined slots engaging this pin. In the lower hinge position the sockets are aligned. When the lower socket is swung upwardly 180.degree., its leaf slots slide downwardly and inwardly. The lower ends of these leaves engage the lower portion of the upper socket, and a bridge extending between the leaves above the pin engages a leaf on the upper socket. This prevents rattling and permits the sockets to be held firmly together, but still far enough apart so that steps on the upper and lower ladder portions may be aligned without touching.

Abstract: A stowable step for use with a vehicle of the type having a body with a door opening therein and a frame beneath and inward from the door opening, a plate hinged to the frame and receiving a stowable tread thereupon, the tread being displacable laterally from the frame below the door opening. Slotted supports and links permit the tread to be compactly stored upon the plate and for the plate to be releasably locked against the vehicle body.
