Energy absorbing element for wall openings and methods of use therefor
First Claim
1. An energy absorber for use in an opening of a wall of a building, the opening defined by a perimeter surface, the wall supporting a closure substantially filling the opening, the closure having respective edges which are substantially parallel to said perimeter surface of the opening, the energy absorber comprising:
- a plate comprising a first planar wall connecting portion having a first mounting aperture for mounting the wall connecting portion to the wall, and a second planar closure connecting portion having a second mounting aperture for mounting the closure connecting portion to the closure, the connecting portions being connected by at least one plastically deformable deforming surface, the mounting apertures being provided at a distance from each other along an axis, the deforming surface comprising at least one linear slot having spaced apart slot portions oriented transversely with respect to the axis, the slot having a length exceeding the distance, whereby the deforming surface is configured to absorb, by plastic deformation, a force applied to the closure.

Abstract
Provided is an energy absorber for use in an opening of a wall of a building, the opening defined by a perimeter surface, the wall supporting a closure substantially filling the opening, the closure having respective edges which are substantially parallel to the perimeter surface of the opening. The energy absorber having a planar wall connecting portion, a planar closure connecting portion and a plastically deformable deforming surface therebetween. The connecting portions being substantially parallel to one another and, the deforming surface adapted to absorb, by plastic deformation, a force applied to the closure.

9. A building comprising:
- at least one opening defining a perimeter surface and fitted with a closure substantially filling the opening, the closure secured to the opening by at least one energy absorber being configured as a plate, the closure having respective edges which are substantially parallel to the perimeter surface of the opening;
the energy absorber comprising a planar wall connecting portion having a first mounting aperture for mounting the wall connecting portion to the wall, and a planar closure connecting portion having a second mounting aperture for mounting the closure connecting portion to the closure, the connecting portions being connected by at least one plastically deformable deforming surface therebetween, the mounting apertures being formed at a distance from each other along an axis, the deforming surface further comprising at least one slot having spaced apart slot portions oriented transversely with respect to the axis, the slot having a length exceeding the distance, whereby the deforming surface is configured to absorb, by plastic deformation, a force applied to the closure.
- at least one opening defining a perimeter surface and fitted with a closure substantially filling the opening, the closure secured to the opening by at least one energy absorber being configured as a plate, the closure having respective edges which are substantially parallel to the perimeter surface of the opening;
