cutting tool

Abstract

A cutting tool is disclosed for permitting a user to selectively chop and saw fibrous material. The cutting tool includes an elongate body having a first end and a second end disposed spaced from the first end. The elongate body defines a handle which is held by the user to hold the cutting tool during use thereof. The elongate body defines a slot and a channel cooperating with the slot. The slot and channel extend between the first end and the second end of the elongate body. A hatchet head is rigidly secured to the first end of the elongate body for selectively permitting chopping of the fibrous material during use of the cutting tool. A saw slidably cooperates with the channel such that in a stowed disposition of the saw, the saw is disposed within the slot and the channel. However, in an operative disposition of the saw, the saw is slidably moved relative to the channel away from the hatchet head for selectively permitting the user to saw the fibrous material.

DETAILED DESCRIPTION OF THE DRAWINGS

[0050] FIG. 1 is a side elevational view of a cutting tool generally designated 10 according to the present invention including a safety sheath 23. As shown in FIG. 1, the cutting tool 10 permits a user (not shown) to selectively chop and saw fibrous material such as firewood for a campfire. The cutting tool 10 includes an elongate body generally designated 12 having a first end 14 and a second end 16 disposed spaced from the first end 14. The elongate body 12 defines a handle generally designated 18 which is held by the user to hold the cutting tool 10 during use thereof. The elongate body 12 also defines a slot 20 which extends between the first end 14 and the second end 16 of the elongate body 12. A hatchet head 22 is rigidly secured to the first end 14 of the elongate body 12 for selectively permitting chopping of the fibrous material during use of the cutting tool 10 after the removal of the protective safety sheath 23.

[0051] FIG. 2 is a similar view to that shown in FIG. 1 but shows the safety sheath 23 having been removed for use of the cutting tool 10 when being used as a hatchet. As shown in FIG. 2, a saw 24 is stowed within the elongate body 12.

[0052] FIG. 3 is an enlarged sectional view taken on the line 3-3 of FIG. 2. FIG. 2. shows the saw 24 in the stowed disposition thereof. As shown in FIG. 3, the saw 24 slidably cooperates with the slot 20 and a channel 25 defined by the elongate body 12 such that in the stowed disposition of the saw 24, as shown in FIGS. 1 to 3, the saw 24 is disposed adjacent to the slot 20 and within the channel 25.

[0053] FIG. 4 is an enlarged view taken on the line 4-4 of FIG. 2. FIG. 4 shows and the saw 24 in the stowed disposition thereof. As shown in FIGS. 1 to 2, the slot 20 does not extend to the second end 16 of the elongate body 12. However, as shown in FIGS. 3 and 4, the channel 25 which communicates with and runs parallel to the slot 20 does extend to the second end 16 of the elongate body 12 for permitting the slidable movement of the saw 24 between the stowed and operative dispositions of the saw 24.

[0054] FIG. 5 is a similar view to that shown in FIG. 2 but shows the saw 24 in the operable disposition thereof. As shown in FIG. 5, the saw 24 is fully extended. More specifically, in an operative disposition of the saw 24 as shown in FIG. 5, the saw 24 has been slidably moved longitudinally along the channel 25 away from the hatchet head 22 for selectively permitting the user to saw firewood and the like. As shown in FIG. 5, the saw 24 is locked in the operable disposition by a simple threaded tensioning fastener generally designated 26. As shown in FIGS. 3 and 4, the fastener 26, includes a thumbscrew 28, so that when the thumbscrew 28 is rotated as indicated by the arrow 27 shown in FIG. 4, the thumbscrew 28 is moved towards the saw 24 for wedging and locking the saw 24 against the slot 20. The arrangement according to the present invention permits locking of the saw 24 in various extended locations a feature which is not possible with the prior art pivoting saw arrangements.

[0055] Additionally, as shown in FIG. 1, the safety sheath 23 includes a further handle

[0056] 30.

[0057] As shown in FIG. 1, the further handle 30 enables the user to securely hold the cutting tool 10 with both hands during a chopping operation. More specifically, the user holds the handle 18 with one hand and the further handle 30 with the other hand.

[0058] In a more specific embodiment of the present invention, the fibrous material

[0059] is wood.

[0060] Moreover, as shown in FIG. 2, the elongate body 12 includes a longitudinal length L which extends from the first end 14 to the second end 16 of the elongate body 12.

[0061] As shown in FIG. 4, the elongate body 12 has a first face 30 and a second face 32 spaced relative to the first face 30.

[0062] Additionally, the elongate body 12 is fabricated from wood.

[0063] In another embodiment of the present invention, the elongate body is fabricated from metal.

[0064] In a further embodiment of the present invention, the elongate body 12 is fabricated from a plastics material.

[0065] Additionally, the plastics material is molded.

[0066] Furthermore, in each of the embodiments of the present invention, the slot 20 extends longitudinally along a portion of the length L of the elongate body 12 such that the slot 20 extends between the hatchet head 22 and the second end 16 of the elongate body 12.

[0067] Also, the slot 20 extends from the first face 30 to the second face 32 of the elongate body 12.

[0068] The channel 25 extends from the slot 20 to the second end 16 of the elongate body 12 for the longitudinal reception therethrough of the saw 24.

[0069] FIG. 6 is a view taken on the line 6-6 of FIG. 2. As shown in FIG. 6, the elongate body 12 defines a transverse opening 34 which is disposed adjacent to the first end 14 of the elongate body 12 for the rigid reception therein of the hatchet head 22 such that the hatchet head 22 is securely fastened to and extends transversely through the transverse opening 34.

[0070] Also, as shown in FIG. 5, the saw 24 includes a proximal end 36 and a distal end 38, the distal end 38 being spaced relative to the proximal end 36.

[0071] As shown in FIG. 4, the saw 24 defines an internally threaded hole 40 disposed adjacent to the proximal end 36 of the saw 24.

[0072] Furthermore, the tensioning fastener generally designated 26 threadably cooperates with the internally threaded hole 40, the tensioning fastener 26 cooperating with the slot 20 such that when the tensioning fastener 26 is rotated relative to the threaded hole 40, as indicated by the arrow 27, the tensioning fastener 26 is selectively urged into a locked disposition relative to the slot 20 at any desired location from the stowed disposition as shown in FIG. 1, to the operative disposition of the saw 24 as shown in FIG. 5.

[0073] Additionally, as shown in FIG. 3, the tensioning fastener 26 includes a threaded stem 44 which threadably cooperates with the internally threaded hole 40, the stem 44 having a first extremity 46 and a second extremity 48. The thumbscrew 28 is rigidly secured to the first extremity 46 of the stem 44 and the second extremity 48 of the stem 44 threadably cooperates with the internally threaded hole 40 of the saw 24. The arrangement is such that when the thumbscrew 28 is rotated as indicated by the arrow 27, the thumbscrew 28 cooperates with the slot 20 for locking the saw 24 at a selected location anywhere from the stowed disposition of the saw 24 as shown in FIG. 1 to a fully longitudinally extended disposition of the saw 24 as shown in FIG. 5.

[0074] In operation of the cutting tool 10 according to the present invention, the hatchet head 22 is used for chopping branches while the saw 24 is locked within the elongate body 12 of the cutting tool 10. The saw 24 is easily extended longitudinally from the elongate body 12 and locked at any desired length of the saw 24 and without having to manually touch the sharp teeth 50 of the saw 24.

[0075] Many modifications and variations of the present invention will be readily apparent to those skilled in the art by a consideration of the detailed description contained hereinafter taken in conjunction with the annexed drawings which show a preferred embodiment of the present invention. However, such modifications and variations fall within the spirit and scope of the present invention as defined by the appended claims.
