Abstract
An apparatus for installing an escape slow lowerer stably at an arbitrary place on a building. The apparatus has a ladder body, horizontal rods mounted on the ladder body and vertical rods mounted slidably and lockably on the horizontal rods to form a gate-like shape for holding the building. The apparatus further comprises a foldable ladder connected to the ladder body and a column having a metal fixture for supporting the escape lowerer.
Claims25
An apparatus for supporting an escape device for slowly lowering a person from a structure toward the ground comprising:
- (a) a ladder assembly having an upper portion for mounting said ladder assembly to said structure, with at least two horizontal bars mounted to said upper portion;
- and
- (b) at least two vertical rods mounted on said at least two horizontal bars such that a gate-like shape is formed by said ladder assembly upper portion, said at least two horizontal bars, and said at least two vertical rods, wherein each of said vertical rods is substantially L-shaped in cross-section and has at least one substantially horizontal cylindrical portion which is adapted to receive one horizontal bar, each said horizontal cylindrical portion being attached to one end of a substantially vertical portion of each said vertical rod and further comprising a threaded section which is adapted to receive a screw for detachably connecting said horizontal bars and said vertical rods to each other, said vertical portions having second ends attached to each other by a lower horizontal member, wherein a portion of said structure is held by and between said ladder assembly and said at least two vertical rods.
An apparatus for supporting an escape device for slowly lowering a person from a structure toward the ground comprising:
- (a) a ladder assembly having longitudinal bars;
- (b) at least two horizontal bars mounted to upper ends of said longitudinal bars;
- (c) at least two vertical bars mounted to said at least two horizontal bars to form a substantially L-shaped holding portion, such that a portion of said structure is held by and between said holding portion and said ladder assembly;
- `(d) a rotatable shaft supported vertically by said holding portion;
- and
- (e) at least two slide rods slidably mounted on said at least two vertical rods, each of said at least two slide rods comprising engaging portions for reciprocatably mounting said at least two slide rods on said rotatable shaft to secure said apparatus to said structure.
An apparatus for removably supporting an escape device on a structure for slowly lowering a person from said structure toward the ground, said escape device comprising a rope operatively connected to a lowering system, said lowering system comprising a centrifugal brake, said apparatus comprising:
- (a) a ladder assembly comprising a plurality of vertical bars;
- (b) a plurality of horizontal bars connected at one end to an upper end of corresponding ones of said plurality of vertical bars;
- (c) a plurality of vertical rods connected at one end to another end of corresponding ones of said plurality of horizontal bars, wherein said apparatus is supported on said structure by said plurality of vertical bars, said plurality of horizontal bars and said plurality of vertical rods, wherein at least one support rod is connected between said plurality of vertical rods, a rotatable shaft being supported in a vertical fashion by said at least one support rod between said plurality of vertical rods, and a foldable handle is positioned on an upper end of said rotatable shaft for rotating said shaft.
An apparatus for removably supporting an escape device on a structure for slowly lowering a person from said structure towards the ground, said escape device comprising a rope operatively connected to a lowering system, said lowering system comprising a centrifugal brake, said apparatus comprising:
- (a) a ladder assembly comprising a plurality of vertical bars;
- (b) a plurality of horizontal bars connected at one end to an upper end of corresponding ones of said plurality of vertical bars;
- (c) a plurality of vertical rods connecting at one end to another one of corresponding ones of said plurality of horizontal bars, wherein said apparatus is supported on said structure by said plurality of vertical bars, said plurality of horizontal bars and said plurality of vertical rods, said plurality of vertical rods being slidably mounted on said plurality of horizontal bars, with each of said plurality of vertical rods having a substantially L-shaped cross-sectional configuration and including a cylindrical portion which is adapted to be inserted on one of said plurality of horizontal bars, said vertical bars having lower ends attached to each other by a lower horizontal member, said cylinder comprising means for locking said vertical rod on a corresponding horizontal bar, each said cylindrical portion comprising means for locking one of said vertical rods on a corresponding horizontal bar, each of said cylindrical portions comprising a threaded portion, and said locking means comprising a screw which is adapted to be screwed into said threaded portion.
