Description

[Detailed Description of the Invention] The present invention relates to an ax that can be safely folded into a compact state when used for camping, mountain climbing, etc.

Conventionally, an ax has a metal blade and a handle made of wood or synthetic resin, and the handle is necessarily long because it is functionally necessary to apply a large amount of downward force. However, when carrying an ax for camping or mountain climbing, it cannot be stored in a bag or rucksack, so it is inserted into a waist belt or hung from a hook. The weight was applied only to the side being carried, which disrupted the rhythm of walking and caused pain in the lower back.It was also a very dangerous tool when used, and walking with such an object hanging exposed on the lower back. His appearance was unimpressive.

The present invention has been devised to eliminate the above-mentioned drawbacks, and will be described below with reference to the drawings.

When the handle is divided into an upper handle 6 and a lower handle 13 at the center and folded inward, the upper handle 6 and lower handle 13 rotate to symmetrical positions, pivoting on the dividing line, and forming a hollow part with an open ventral surface. 14.14' is provided on the upper handle 6 and the lower handle 13, and the blade 1 rotates at the base end of the blade 1, which has a protrusion 2 on the peak at a position above the upper handle 6, and the lower part is inserted into the hollow part 14 at a position where it is inserted into the hollow part 14, and a cutout hole 4 is provided in the back surface of the upper handle 6 into which the protrusion 2 connected to the blade 1 is fitted. The tip piece 3 has a hole for fitting, the middle part passes through the hollow part 14, and the rear end has a long side plate 5 formed into a hook 8, which protrudes from an insertion hole 7 provided at a lower position on the back of the upper handle 6. The lower handle 13 has a blade 1 folded inward.
It has a hollow part 14' on the ventral surface into which the upper part is inserted, and is covered from the back side of the lower handle 13 and hooks onto a protrusion 2 protruding from the base end of the upper handle 6 at the tip of the lever handle 12 which serves as a lever. A lever handle 1 is attached to a hook 8 provided at the rear end of the long side plate 5 that is hooked to the protrusion 2 of the blade 1 at the rear of the pivoting position.
This is a new ax with a ring 9 attached at a position where the rear part 2 of the lever handle 12 is pulled up and latched, and the rear part of the lever handle 12 is pushed down and overlaps the lower handle 13 to generate tension.

Since the present invention is a folding ax having the above-mentioned characteristics, when in use, the upper part 6 and the lower handle 13 which are pivoted at the central position are opened, and the bottom part of the upper part 6 and the top of the lower handle 13 are opened. By pulling out the blade 1 while the blades 1 are in contact with each other, the continuous protrusion 2 protrudes from the notch hole 4, and the hole provided in the tip piece 3 at the tip of the long side plate 5 is fitted into this, and the rear end hook 8
With the rear of the lever handle 12 pulled up, the lever handle 1 is
When the ring 9 attached to the upper part 2 is hooked and the lever handle 12 is pushed down until it reaches the position where it overlaps the lower handle 13, a hook 11 at the end connected to the lever handle 12 is attached to the protrusion protruding from the base end of the upper part 6. 10, the blade 1 protrusion 2 of the long side plate 5 tip piece 3 is strongly fixed under tension, resulting in an ideal ax with a long handle. When stored, the tension state is lost by pulling up the rear of the lever handle 12 as shown in FIG.
By removing the hole in the tip piece 3 hooked to the blade 1 from the protrusion 2, the blade 1 is folded inward, the lower part is fitted into the hollow part 14, and the lower handle 13 is connected to the upper part 6. By folding to a symmetrical position, the upper part of the blade 1 is fitted into the hollow part 14 of the lower handle 6, and the lever handle 12 is overlapped with the lower handle 6 to complete the process. The size is a rectangular body with a slightly larger area than the blade 1, so even if you put it in a bag or rucksack, the blade 1 will remain safely stored in the hollow part 14.14' of the upper part 6 and the lower handle 13. It is a useful item and is convenient to carry, and its value is extremely great.

Claims (1)

[Scope of utility model registration request] When the handle is divided into an upper handle 6 and a lower handle 13 at the center and folded inward, the upper handle 6 and lower handle 13 rotate to symmetrical positions, pivoting on the dividing line, and forming a hollow part with an open ventral surface. 14.14' is provided on the upper handle 6 and the lower handle 13, and the blade 1 rotates at the base end of the blade 1, which has a protrusion 2 on the peak at a position above the upper handle 6, and the lower part is inserted into the hollow part 14 at a position where it is inserted into the hollow part 14, and a cutout hole 4 is provided in the back surface of the upper handle 6 into which the protrusion 2 connected to the blade 1 is fitted. The tip piece 3 has a hole for fitting, the middle part passes through the hollow part 14, the rear end has a hook 8, and the long side plate 5 has a bottom shape. The lower handle 13 has a hollow part 14' on the ventral surface into which the upper part of the blade 1 folded inward is inserted, and is covered from the back side of the lower handle 13 and pivoted at the upper position. A hook 11 is provided at the tip of a lever handle 12 serving as a lever to be hooked to a protrusion 10 protruding from the base end of the upper handle 6. A long side plate 5 is attached to a protrusion 2 of the blade 1 at the rear of the pivoting position. A ring 9 is mounted in a position where the rear part of the lever handle 12 is pulled up and hung on a hook 8 provided at the rear end, and the rear part of the lever handle 12 is pushed down and overlaps the lower handle 13 to generate tension.
