Abstract
An axe head is attached to a handle in a manner that utilizes the inertia of the axe head to bear against a structure that resists separation of the axe head from the handle. In one example, that structure is a key that fits within the handle after the axe head is slid onto the handle, resisting passage of the axe head past the key. In another example, at least one end piece is joined to a narrowed, toothed section of the handle, forming an assembly with a friction fitted portion and an end portion with a diameter that exceeds the diameter of the hole in the axe head, retaining the axe head on the friction fitted portion of the handle assembly.
Claims11
An axe, comprising:
- a head having an opening therethrough, the opening extending from a top surface to a bottom surface, the opening having a wall defining a channel therein, the channel extending from an intermediate portion of the opening to the top surface of the opening, the channel having a width;
- a handle having a head attachment portion fitting within the opening, the head attachment portion having a hole therein, the hole having a width or a diameter that is substantially identical to the width of the channel, the hole further having a depth;
- and
- a key having a length that is greater than the depth of the hole, the key further having a width or a diameter that is substantially identical to the width or diameter of the hole.
The axe according to claim 4, wherein:
- the handle defines a channel therein, the channel being substantially aligned with the fastener holes;
- and
- the clamping fastener passes through the channel defined in the handle when the head is fastened to the shaft.
An axe, comprising:
- a head having a body including a cutting edge and a pair of flanges extending opposite the cutting edge, the head having an opening passing between the flanges, the opening extending from a top surface to a bottom surface, each of the flanges defining at least one fastener hole disposed opposite the body;
- a handle having a head attachment portion fitting within the opening;
- and
- a clamping fastener passing through the fastener holes, the clamping fastener including a nut having a convex curved surface abutting a corresponding concave curved surface defined on one flange, and a threaded fastener passing through the fastener hole of the other flange and engaging corresponding threads defined within the nut.
The axe according to claim 7, wherein:
- the handle defines a channel therein, the channel being substantially aligned with the fastener holes;
- and
- the clamping fastener passes through the channel defined in the handle when the head is fastened to the shaft.
An axe, comprising:
- a head having an opening therethrough, the opening extending from a top surface to a bottom surface, the opening having a width;
- a handle assembly having a shaft and at least one end piece, the shaft having a head attachment portion defined proximate to one end, the handle attachment portion having a width that is less than the width of the opening of the head, the handle attachment portion and end piece each defining an interlocking surface that interlocks with the other interlocking surface, the end piece defining an intermediate portion fitting within the opening with a friction fit when joined to the shaft, and an end portion that is larger than the opening in the head when joined to the shaft.
