A stair cage is a stair assistance apparatus having a rail attached to the wall on each side of a staircase, and two horizontal rails spaced horizontally apart but joined by cross bars and having wheels rotatably attached to the ends of the cross bars and engaged in tracks within the horizontal rails so that the cross bars are able to move up and down the stairway. A brake system having a brake assembly in the wheels and squeeze brake handles on the cross bars so that the user can control the descent or hold position on the ascent.

A handrail system that is constructed and arranged to be coupled to a stairwell such that at least a portion of a hand railing may be in an upright position or a lowered position. In an upright position, the system provides a complete top-to-bottom handrail. In the lowered, stowed position, the upper railing portion is conveniently stowed away within the stairwell. In a bulkhead embodiment, a full handrail is provided in the upright, use position and the upper railing is stowed within the bulkhead when the bulkhead doors are closed.

The present disclosure relates to a falling and death leap defense rotating cylinder system, including a supporter; a rotator that is rotatably installed in the supporter, and that inhibits a death leap of a death leap attempter by rotating when grasped by the death leap attempter; and a spiked unit that forms a cutting edge, and that is detachably installed in any one or more of the supporter and the rotator. According to the present disclosure, by the spiked unit detachably installed in the supporter or the rotator, a falling and death leap of a death leap attempter may be inhibited more effectively.

A deck framing device relates to a clamp-based system that can be safely implemented without risk of damaging rails, banisters, or other such existing mounting structures. A set of clamps allows the apparatus to mount securely and removably atop a deck, especially the railing of a deck. The clamps may be adjustable to accommodate for different widths of railings or supports. A vertical post extends upwards from around each of the clamps. These vertical posts are connected by horizontal beams that are optimized for the support of various items, including, but not limited to, curtains, ornamental lighting fixtures, blankets, and more. In many versions, the horizontal beams may expand telescopically to allow for customizable length adjustment or may be cut down to an appropriate size and fit into hinged supports extending from the top portions of the vertical posts. Various threaded fasteners ensure that customization is both convenient and intuitive.

The present disclosure relates systems and methods involving movable/adjustable guardrails. An example system includes a frame weldment and a rail assembly attached to the frame weldment. The rail assembly includes a first post and a second post. The base portion of the first post is rotatably coupled to a first pivot point of the frame weldment and the base portion of the second post is rotatably coupled to a second pivot point of the frame weldment. The system also includes a top rail rotatably coupled between a top portion of the first post and a top portion of the second post. The system yet further includes an actuator configured to controllably adjust a configuration of the rail assembly between an extended configuration and a retracted configuration with respect to the frame weldment.

An elbow joint connector includes an elbow portion and a locking mechanism detachably coupled to a distal end of the elbow portion. The locking mechanism including a pair of locking members translatable relative to one another along an interface transverse to a longitudinal axis of the elbow joint connector. Divergent translation of the pair of locking members relative to one another along the interface increases a portion of an outer periphery of the locking mechanism to lock the elbow portion to an adjoining member. The elbow joint connector is configured for detachable coupling to an adjoining elbow joint connector and pivotally rotatable relative thereto from a first configuration in which respective center axes of the connectors form an acute angle to a second configuration in which the respective center axes are collinear.

An adjustable glass windscreen system including an elongate shoe secured atop a supporting surface with inner and outer vertical shoe walls journaled into a baseplate to define a track. A glass adjustment block is seated within the track of the shoe, likewise a three-walled open-top framing member defining a track. A glass panel is seated in the glass adjustment block. The width of the adjustment block is less than the track of the shoe to allow lateral adjustment. Buffer pads line the inside top edges of the opposing inner and outer shoe walls. Adjustment bolts are threaded through the inner and outer shoe walls and penetrate the bottom base of the glass adjustment block for back-and-forth adjustment thereof, and hence the glass panel seated therein. This cantilevers the glass panel about the buffer pads and amplifies the adjustment upward to the upper edge of the glass panel.

A brake system having a brake assembly in the wheels and squeeze brake handles on the cross bars so that the user can control the descent or hold position on the ascent.

An emergency slide system to provide an evacuation of a high-rise building comprises a plurality of slide assemblies configured for movement from a first stowed position to a second deployed position. Each of the plurality of slide assemblies are built into a wall adjacent each of the flights of stairs disposed in the stairwell of the building. Each of the plurality of slide assemblies is disposed in a storage enclosure built into the wall adjacent each of the flights of stairs disposed generally parallel to the flights of stairs designed to zig zag down from an upper floor of the building to a lower floor. Each of the slide assemblies is constructed of an elongated escape chute to enable a person exiting the building to slide down a plurality of the elongated escape chutes between the upper and lower floors disposed in the stairwell of the high-rise building.
