Wall-clamping Means Patents (Class 182/60)
  • Patent number: 7753334
    Abstract: The invention is a window safety harness which can be clamped to the frame of a window and which provides a solid anchor point for a person working around the window. The device includes a bar for placement inside the window, a bar for placement outside the window, and a connecting piece which holds the bars in rigid, spaced apart relation to each other. Each end of both the inside and the outside bar have contact pads which are configured to contact the window frame. They also include a tightening mechanism which tightens the contact pads against the window frame and secures the device in the window frame. An anchor point allows a worker to attach himself to the anchor point for work outside the window, or to anchor a line to the window frame.

  • Patent number: 7195100
    Abstract: A system and method for allowing escape of many persons from a multistory building over a short period of time. The method and system include strategic placement and use of anchor points and components in conjunction with escape kits or devices so as to allow increased efficiency and safety of escape from the building for a plurality of persons in a coordinated manner, including escape of multiple escapees simultaneously or near simultaneously. The system and method include determining a strategic escape plan and configuration that incorporates consideration of building features, including features possibly interfering with escape routes, and three dimensional aspects of both building characteristics and anchor and escape kit and device features.

  • Patent number: 7044313
    Abstract: A portable hoist for preferably lifting and moving a trowel machine is disclosed. The portable hoist is comprised of a base and a plurality of legs coupled with the base. A foot is rotatably attached to one end of each of the legs. The rotatable attachment allows the foot to move about the end of the leg that the foot is attached to. The legs and the feet are used to secure the hoist, typically to a foundation wall. Also coupled with the base is a boom, and a winch is further coupled with the boom. The boom and winch allow the hoist to be used to raise and lower an object.

  • Patent number: 6135300
    Abstract: A parapet-mounted hoist made from an elongated cradle. The cradle is essentially a rectangular box-shaped mounting frame having two pairs of mounting frame legs secured to the parapet with cradle bolts. A steel square tubed safety brace mount is seated between an inside surface of the cradle's top frame, and the parapet wall. The safety brace mount has a back segment extending slightly beyond a rear plane of the mounting frame, and a forward segment extending slightly beyond a front plane of the mounting frame. The safety brace mount has a threaded safety brace pin penetrating its wall. An elongated steel safety brace having a proximal end positioned within the back segment of the safety brace mount. A boom mount having a vertically oriented cradle stub is disposed on the outside surface of the cradle. The cradle stub has a lower end affixed to the outside surface, and an upper end supporting two parallel, horizontal mounting plates.

  • Patent number: 5265742
    Abstract: A hoist apparatus for lifting objects up the side of a building or the like and swinging the objects onto the roof or other surface. The hoist can be erected and operated by one person and can be folded into a compact, easily moved, package. A pair of spaced triangular leg assemblies are typically clamped to the edged of the roof parapet in a spaced relationship. Each triangular assembly when installed for this use is made up of a first leg formed by one beam that is a vertical portion of the clamp and a flexible extension, such as a chain, extending from the lower end of the beam, a second leg secured at one end to the free end of the extension and a third leg pivotally connected between the second ends of the first and second legs, forming a triangle with an acute angle between the second and third legs. A cross beam extends between the second and third leg connections and is adapted to carry a hoist, typically a block and tackle arrangement.

  • Patent number: 4428457
    Abstract: A window bracket is constructed to be supported on a window sill and the walls beneath the sill of an open window and further constructed to hold a safety scaffold to permit work on the exterior of the building, either on the windows or the area between windows. It may be used in pairs to hold a scaffold or in greater numbers where the scaffold is longer and extends over a greater area of the building exterior. It is rigidly constructed by welding of steel or aluminum alloy for rapid installation through open windows and is equipped with safety railings and reinforcing brackets to insure complete safety of workmen working on the outside of the building, such as repairing the exterior wall, painting or washing or repairing the windows from the exterior of the building.

  • Patent number: 4320816
    Abstract: There is disclosed a window perch so that access to the outside of a sash window may be had even though the window may be considerably above the ground. The perch does not depend on ground support, but on the contrary depends on the wall area located immediately below the window sill. The perch comprises a clamping arrangement that clamps to the stated wall area. Suitable bracket means extend normally to the outer wall portion of the stated wall area which carry a planar member upon which a workman may stand or may be seated. A safety railing is provided vertically displaced from the planar member which is suitably affixed to the planar member and the stated clamping arrangement. The perch is constructed in a manner so that it may be conveniently collapsed so that it may be more easily positioned and retrieved through the sash window and may be stored when not in use.
