Abstract
A hole cutting device comprises a spike for driving through a sheet of material; at least one handle located on the spike at an end opposite to that of the tip of the spike; a first cutting member located on the spike and substantially adjacent the handle, a cutting edge of the first cutting member to be positioned substantially adjacent a first side of the sheet of material; a second cutting member located on the spike and joined with the first cutting member, a cutting edge of the second cutting member to be positioned substantially adjacent a second side of the sheet of material; and the handle moving the first cutting member toward the second cutting member to cut a hole in the sheet of material by the cutting edges.
Claims15
A hole cutting device characterised in that the device includes:
- a spike having a tip end and capable of being driven through a sheet of material;
- at least one manually operated handle which is or can be located on the spike at the opposite end to that of the tip end;
- a first cutting member having at least one cutting edge and capable of being located on the spike such that:
- a) the first cutting member is positioned substantially adjacent the at least one handle;
- and
- b) the cutting edge of the first cutting member can be positioned substantially adjacent a first side of the sheet of material;
- a second cutting member having at least one cutting edge and capable of being located on the spike such that:
- a) the spike is joined with the second cutting member;
- and
- b) the cutting edge of the second cutting member can be positioned substantially adjacent a second side of the sheet of material;
- the device further characterised in that the at least one handle is adapted so as to be capable of moving the first cutting member along the spike towards the second cutting member so as to cause the respective cutting edges of the cutting members to cut a hole in the sheet of material therebetween.
A kit of parts for assembling a hole cutting device, said kit including:
- a) a spike having a tip end and capable of being driven through a sheet of material;
- b) at least one manually operated handle which is or can be located on the spike at the opposite end to that of the tip end;
- c) a first cutting member having at least one cutting edge and capable of being located on, the spike such that:
- (i) the first cutting member is positioned substantially adjacent the handle;
- and
- (ii) said first cutting member capable of being moved along the spike by said at least one handle;
- (iii) the cutting edge of the first cutting member can be positioned substantially adjacent a first side of the sheet of material,
- d) a second cutting member having at least one cutting edge and capable of being located on the spike such that:
- (i) the spike is joined with the second cutting member;
- and
- (ii) the at least one cutting edge of the second cutting member can be positioned substantially adjacent a second side of the sheet of material.
