Protective device

Claim 2

A protective device for a building adapted to be installed at a window to prevent ingress, the device comprising: a first member adapted to be attached to one edge of the window; a second member adapted to be mounted to a further edge of the window, opposed to the first member; each member being a channel member of generally U-shape, the U having limbs joined by a bridge, with a flange extending from one limb of the U, remote from the bridge; holes to receive screws formed in the flange; recesses formed in the bridge of the U at predetermined centers; a bar extending between a pair of opposed recesses to prevent ingress, holes extending through a limb of the U adjacent the flange to permit locating means to extend into the channel member to locate the bars, the bars also being located by the attachment of the members to the window edges.

Claim 3

A protective device for a building adapted to be installed at a window to prevent ingress, the device comprising: a first member adapted to be attached to one edge of the window; a second member adapted to be attached to a further edge of the window, opposed to the first member; each member being a channel member of generally U-shape, the U having limbs joined by a bridge, with a flange extending from a limb of the U, remote from the bridge; recesses formed in each member at predetermined centers in one limb of the U; a bar extending between a pair of opposed recesses to prevent ingress, holes extending through the bridge of the U to permit locating means to extend into the channel member to locate the bars, the bars also being located by the attachment of the members to the window edges.

Claim 4

A protective device for a building adapted to be installed at a window to prevent ingress, the device comprising: a first member adapted to be attached to one edge of the window; a second member adapted to be attached to a further edge of the window, opposed to the first member; each member being a channel member of generally U-shape, the U having limbs joined by a bridge, with a flange extending from a limb of the U, remote from the bridge; recesses formed in each member at predetermined centers in one limb of the U; a bar extending between a pair of opposed recesses to prevent ingress, holes extending through the bridge of the U to permit locating means to extend into the channel member to locate the bars, the bars also being located by the attachment of the members to the window edges.

Claim 5

A kit of parts for a protective device to be installed at a building window to prevent ingress through the window, the kit comprising a channel member of generally U-shape, the U having limbs formed by a bridge with a flange extending from a limb of the U, remote from the bridge, the channel member being of a length so that it can be cut to lengths to fit at both edges of the window; recesses formed in the channel member in the bridge of the U at predetermined centers; at least one bar length in the kit that can be cut to provide a plurality of bars, each bar to be positioned to extend between a pair of opposed recesses to prevent ingress at the building window; holes in the channel member extending through a limb of the U, adjacent the flange to permit locating means to extend into the channel member to locate the bars.

Claim 6

A kit of parts for a protective device to be installed at a building window to prevent ingress through the window, the kit comprising a channel member of generally U-shape, the U having limbs formed by a bridge with a flange extending from a limb of the U, remote from the bridge, the channel member being of a length so that it can be cut to lengths to fit at both edges of the window; recesses formed in the channel member in the bridge of the U at predetermined centers; at least one bar length in the kit that can be cut to provide a plurality of bars, each bar to be positioned to extend between a pair of opposed recesses to prevent ingress at the building window; holes in the channel member extending through a limb of the U, adjacent the flange to permit locating means to extend into the channel member to locate the bars.

Claim 7

A kit as claimed in claim 3 including the necessary screws to mount the device at a window.

Claim 8

A kit of parts for a protective device to be installed at a building window to prevent ingress through the window, the kit comprising a channel member of a generally U-shape, the U having limbs joined by a bridge, with a flange extending from a limb of the U, remote from the bridge, the channel member being of a length so that it can be cut to a length to fit at both edges of the window; recesses formed in the channel member in one limb of the U, remote from the flange; holes to receive screws formed in the flange; at least one bar length in the kit that can be cut to provide a plurality of bars, each bar to be positioned to extend between a pair of opposed recesses to prevent ingress; holes in the channel member extending through the bridge of the U, adjacent the flange, to permit locating means to extend into the channel member to locate the bars.

Claim 9

A kit of parts for a protective device to be installed at a building window to prevent ingress through the window, the kit comprising a channel member of a generally U-shape, the U having limbs joined by a bridge, with a flange extending from a limb of the U, remote from the bridge, the channel member being of a length so that it can be cut to a length to fit at both edges of the window; recesses formed in the channel member in one limb of the U, remote from the flange; holes to receive screws formed in the flange; at least one bar length in the kit that can be cut to provide a plurality of bars, each bar to be positioned to extend between a pair of opposed recesses to prevent ingress; holes in the channel member extending through the bridge of the U, adjacent the flange, to permit locating means to extend into the channel member to locate the bars.
