Description

A CARPENTRY DEVICE

Field of the Invention

The present invention relates to a carpentry or glazing device, in particular but not exclusively a device for installing beading around windows or similar/

Background

Increasing numbers of people take pride in their surroundings, and an increased awareness of domestic and commercial property worth and sustainability is a factor in many societies.

In improving sustainability of many properties, it is key to have well insulated and 15 good quality glazing.

Removing and replacing the beading on glazing panels, windows or doors, can be problematic, particularly in ensuring that the beading is inserted correctly, securely and efficiently into the required spacing.

Prior Art

US 5 690 316 (MADJARAC) discloses an improved timber wedge featuring an elongated wedge shaped body formed of natural materials such as wood or plastic or other synthetic material. The wedge shaped body is protected from hammer blows incurred during use by a removable impact protection cap mounted upon the striking end of the wedge which also reinforces the wedge body at the impact end. The cap is held to the body by a screw therethrough which friction mounts to cooperating threads in the wedge body intelor or cooperatively engages a nut in an in line relationship with the screw and accessible from the side of the wedge. Releasable glue may also be used to hold the impact resistant cap to the wedge shaped body.

CA 2 050 763 (JESKE) discloses a device fabricated in the exact configuration of a 35 plastic wedge commonly used in the logging industry. To use it, a plastic wedge is inserted into the metal sheath and both are simultaneously driven into the wood by hammer force striking the plastic wedge. Specification This invention relates to a manually driven wedge used for splitting wood. The plastic only wedges now in use are very frail relative to the forces they are subjected to, and therefore have al limited lifespan. The plastic only wedges are also somewhat flexible which often causes them to bounce forcibly out of their intended direction. This makes them hazardous to the workman, and the plastic wedges cover enough distance to make retrieval difficult. An all-steel wedge is dangerous because of steel particles dislodged by the force of steel (i.e. hammer) on steel wedge. Further, the weight of allsteel wedges make them impractical to handle and carry.

FR 2 431 351 (BRUNON) discloses a device for working wood or similar soft materials, the board-bladed chisel comprises a blade with an integral handle of which the tip is designed to receive direct hammer blows. The active cutting edge is incorporated on a thin broad blade, and may be formed by mono-bevelling. In addition the sides of the blade may be similarly bevelled on the same face, and the sides may subtend angles of nominally less than 90 degrees with the cutting edge to provide cutting clearance. The blade section may be straight curved or of a V-shape with a varying included angle. The tip may be of treated steel for ease of filling, and may be enlarged to afford hand protection. Finally the tool may comprise a one piece forging or may be fabricated by welding a blade to a metal handle.

The present invention arose in order to overcome problems suffered by existing devices.

Summary of the Invention

According to the present invention there is provided a carpentry device comprising a body with a first end and a second end, wherein the first end is arranged for striking, and the second end provides a driving surface, wherein the first end is larger in 30 surface area than the second end and the driving surface is resiliently deforrriable.

In some embodiments the device may be substantially triangular in profile, wherein the body may be arranged to narrow or taper from the first end to the second end.

In some embodiments the body may comprise tapering, for example wherein the*tapering may be substantially continuous so as to provide a wedge shaped body.

In other embodiments the tapering may be concentrated. For example only some of the body may be tapered. In some embodiments the second end may be tapered at a different tapering angle to the remainder of the body.

In some embodiments the striking surface may be provided by a separate or separable part or material or bodily form or shape.

In some embodiments the striking surface may be provided by a separate or 10 separable part or material or bodily form or shape.

In some embodiments the device may comprise a handle.

Such handle may be provided by an enlarged or diminished section of the body. In 15 other embodiments the handle may comprise a deviation from, or a separate, part to, the body.

In some embodiments the body may be provided in a metal or alloy. Such material may be coated or covered, for example covered with a silicone overmould.

In some embodiments the body may be provided in a plastics material, such as polyethylene or acrylonitrile butadiene styrene (Pas).

In some embodiments the driving surface may be provided in a silicone or rubber, 25 which may be envisaged to have a Shore hardness in excess of 70.

In some embodiments the driving surface may comprise a substantially flat surface, for example providing a flattened second end with respect to any tapering.

In some embodiments the driving surface may comprise a substantially rectangular surface, for example so as to provide a narrow rectangular fillet.

Such fillet may be sized appropriately to be used to engage a window frame bead, and may be envisaged to be an elongate rectangular shape, so as to follow the 35 beading spacing.

In this way it may be envisaged that the device may assume a largely rectangular or narrow profile, so as to enable the user to approximate the glass above the beading.

The device may have a handle that includes a pinched waist in profile for example 5 such that the user is enabled to hold the device whilst holding the device largely vertical above the beading without their hand interfering with the glass.

In this way in some embodiments the device may be envisaged to be of' use in placing beading into glazing such as windows or doors, and securing the beading 10 into the spacing between the glass and frame of glazing.

A preferred embodiment of the invention will now be described by way of example only and with reference to the Figures in which:
