## Abstract

A blast resistant window system comprising a reinforced window pane defining an in-side and an out-side and being supported by a window framework for mounting at an opening in a wall. The window system further comprises at least one pane-engaging member transversally extending adjacent an in-side surface of the window pane and secured at respective ends thereof to opposite construction elements. Each of the pane-engaging member is fitted with at least one energy dispensing device for converting axial force within the pane-engaging member into mechanical work.

## Claims

### Claim 1

A blast resistant window system, comprising:
anchors fixed to a wall;
a reinforced window pane supported by a framework assembled of a plurality of profiled members and being receivable within an opening in a wall;
a frame support member to impart the framework improved durability and resistance to blast, said frame support member extending within the profiled members; the frame work including a plurality of openings through which the frame support member projects to engage with corresponding anchors.

### Claim 2 (depends on 1)

A blast resistant window system according to claim 1, in which said frame support member includes at least one energy dispensing device fitted thereon.

### Claim 3 (depends on 2)

A blast resistant window system according to claim 2, wherein the energy dispensing device, further comprises:
a first member having a longitudinal axis;
a second member;
at least one of said first and second members being fixedly attachable to a respective end of a substantially non-elastic window pane engaging member;
one or both of the first and second members include at least one energy wasting member extending along the longitudinal axis, said at least one wasting member bearing against a cooperating surface of the respective other first and second member, wherein axial displacement of the first and second members with respect to one another is converted into a different form of work.

### Claim 4 (depends on 1)

A blast resistant window system according to claim 1, wherein the window is a fixed casement window and wherein the frame support member is made of a substantially flexible, but not elastic material.

### Claim 5 (depends on 1)

A blast resistant window system according to claim 1, wherein there is further provided a transversal profiled member having respective opposite ends articulated to the profiled members which are situated at the respective opposite ends of the transversal profiled member.

### Claim 6 (depends on 5)

A blast resistant window system according to claim 5, in which said transversal profiled member extends adjacent an in-side of the window pane.

### Claim 7 (depends on 5)

A blast resistant window system according to claim 5, in which there is further provided a transversal frame support member extending through the transversal profiled member.

### Claim 8 (depends on 1)

A blast resistant window system according to claim 1, further comprising:
at least one tensioning member extending within the profiled members, for tensioning the frame support member.
