Description

Semi-elastic knife

This work is about a hand-held cutting tool, especially a hand-held cutting tool with a rotatable blade.

The folding knife can reduce the volume and facilitate the storage by the characteristics of the blade portion being accommodated in the handle portion. Therefore, it is one of the necessary tools for people who often engage in camping, climbing or fishing. One type of folding knife is a semi-elastic knife. The semi-elastic knife has an elastic mechanism. When the semi-elastic knife is to be opened, the blade must be opened to a certain extent, and the elastic mechanism acts. The force is applied to the blade to completely open the blade.

In the existing semi-elastic knives, based on safety considerations, a lock is often provided to fix the angle between the blade portion and the handle portion. For example, the blade portion that is prevented when the blade portion of the half-knife is folded over the handle portion can be ejected, or the blade portion can be prevented from being folded when the blade portion is opened. However, the existing lock can not achieve the effect of preventing the blade portion from being ejected and preventing the blade portion from being folded through a lock at the same time, and the protection effect is insufficient.

In view of this, providing a better improvement solution is an urgent problem to be solved in the industry.

The main purpose of this creation is to provide a semi-elastic knife that prevents the blade from being folded in the open state and prevents the knife from opening when in the folded state.

In order to achieve the above object, the semi-elastic knife proposed by the present invention has: a casing; a blade pivotally disposed on the casing, and the blade has a stopping portion and a first abutting portion; and a pressing member pivoting Provided in the outer casing, the pressing member has a second abutting portion and a pressing portion, the second abutting portion selectively abuts against the first abutting portion of the blade; an elastic member Connecting with the pressing member, and providing a pushing force of the pressing member to abut the second abutting portion; and a control piece movably received in the outer casing, and the The control piece includes a first locking portion and a second locking portion, the first locking portion selectively abuts the stopping portion, and the second locking portion selectively abuts against the pressing portion Wherein the semi-elastic knife defines an open state and a folded state, the blade pivots to the outside of the outer casing when the semi-elastic knife is in the open state; when the semi-elastic knife is in the folded state, the The blade pivots into the outer casing; one end of the movement stroke of the control piece is defined as a locking position; when the semi-elastic knife is at the receiving position a state, and when the control piece is moved to the locking position, the first locking portion abuts against the stopping portion to prevent the blade from pivoting to the open state; when the semi-elastic blade is in the open state, and When the control piece moves to the locking position, the second locking portion abuts against the pressing portion to keep the second abutting portion against the first abutting portion to prevent the blade from facing the The folding state pivots.

Therefore, the present invention has the advantage that by moving the control piece to the locking position, the first locking portion on the control piece can selectively engage the stop portion of the cutting edge in the folded state to prevent the semi-elastic knife from opening. And in the open state, the second locking portion on the control sheet can be abutted against the pressing portion fixed to the pressing member to prevent the half knives from being folded. Compared to the prior art semi-elastic knives, which only prevent the blade from opening or only prevent the blade from folding, this creation provides more comprehensive protection.

First, please refer to FIG. 1 to FIG. 3 to explain the use method of the semi-elastic knife of the present invention. The semi-elastic tool proposed by the present invention has a casing 10, a blade 20, a control piece 30, a pressing member 40, and an elastic member 50.

The outer casing 10 is a half-knife handle portion, and may include a first casing 10a and a second casing 10b. The first casing 10a is opposite to the second casing 10b with a gap therebetween, and the gap is provided with a blade. 20 and the pressing member 40. The inside of the housing 10 has a pivot 11 and a receiving slot 12, and in the embodiment, the pivot 11 and the receiving slot 12 are located on the inner side of the first housing 10a. The accommodating groove 12 is a long groove and extends in a direction parallel to the longitudinal direction of the blade 20.

In addition, in the present embodiment, the first housing 10a of the outer casing 10 further has a through hole 13 and the through hole 13 is an elongated hole extending in a direction parallel to the longitudinal direction of the blade 20. In the embodiment, the through hole 13 can communicate with the accommodating groove 12. The inner side of the first housing 10a of the outer casing 10 may also have an arcuate guide groove 14. It partially surrounds the pivot shaft 11 and the guide groove 14 communicates with the accommodating groove 12. Both ends of the guiding groove 14 can respectively define a folding end and an opening end.

The blade 20 is pivotally mounted to the outer casing 10 with the pivot shaft 11 as a rotating shaft. Specifically, it is selectively located between the first housing 10a and the second housing 10b by pivoting. The blade 20 has a stop portion 21 and a first abutment portion 22. The stop portion 21 projects laterally from the blade edge 20 and is adjacent to the pivot shaft 11, and the stop portion 21 is movable within the guide groove 14 when the blade edge 20 is pivoted to limit the angle at which the blade edge 20 pivots. The first abutting portion 22 is formed at the other end of the blade edge 20 opposite to the blade edge, and is located between the first casing 10a and the second casing 10b. The first abutting portion 22 has a hook shape and protrudes upward.

The pressing member 40 is disposed in the outer casing 10 and is pivotally disposed on the second casing 10b. Specifically, it is a gap between the first casing 10a and the second casing 10b. The pressing member 40 has a second abutting portion 41 at one end and a pressing portion 42 at the other end. The second abutting portion 41 has a hook shape and a shape corresponding to the first abutting portion 22 such that the second abutting portion 41 can selectively abut the first abutting portion 22 .

The pressing portion 42 protrudes laterally from both side faces of the pressing member 40, one end of the pressing portion 42 abuts against the elastic member 50, and the other end selectively abuts against the second locking portion 32 of the control piece 30. However, in other embodiments, the elastic member 50 or the control portion 30 may directly abut against the lower surface of the pressing member 40 or respectively abut against the different projections on the side of the pressing member 40.

Please refer to FIG. 3 and FIG. 4 next. The elastic member 50 is a resilient piece having one end disposed on the second housing 10b and the other end connected to the pressing member 40. In the present embodiment, one end of the pressing portion 42 against the elastic member 50 is pressed down against and abuts against the elastic member 50. In other words, the elastic member 50 provides an upward thrust of the pressing member 40 to pivot the second abutting portion 41 of the pressing member 40 to abut against the blade 20.

The semi-elastic can define a folded state and an open state. When the half knives are in the folded state, the blade 20 is pivoted between the first housing 10a and the second housing 10b, and the stop portion 21 of the blade 20 is located at the folded end of the guide groove 14.

When the semi-elastic is in the open state, the blade 20 is pivoted out of the outer casing 10 and in line with the outer casing 10, and the stop portion 21 is located at the open end of the guide groove 14, and the first abutment portion 22 of the blade 20 is hooked. The second abutting portion 41 of the pressing member 40. On the other hand, the thrust of the elastic member 50 continues to urge the pressing member 40 and prevents the pressing member 40 from pivoting, so that the first abutting portion 22 cannot be disengaged from the second abutting portion 41, so that the blade 20 is fixed and cannot be pivoted. To ensure safety.

When the semi-elastic blade is brought into the folded state from the open state, first, the pressing member 40 is not provided with the end of the second abutting portion 41, and the pressing member 40 is pivoted. When the pressing member 40 is pivoted, the first abutting portion 22 is disengaged from the second abutting portion 41, so that the blade 20 can be pivoted and folded. Subsequently, the blade 20 is pivoted between the first housing 10a and the second housing 10b of the outer casing 10 to complete the storage, so that the semi-elawing knife is in a folded state.

When the semi-elastic blade is brought into the open state from the folded state, only the portion where the blade 20 is exposed outside the outer casing 10 is applied, and the blade 20 is pivoted to be in line with the outer casing 10.

The following describes the method of locking the semi-elastic knife of the present creation.

The control piece 30 is movably received in the accommodating groove 12 of the first casing 10a, and the direction in which the control piece 30 moves in the present creation is parallel to the longitudinal direction of the blade 20. The two ends of the movement stroke of the control piece 30 are respectively defined as a locking position and an unlocking position. In the embodiment, the front end of the receiving groove 12 is a locking position. When the control piece 30 is moved to the locking position, the blade 20 or the pressing member 40 is fixed by the control piece 30 and cannot be pivoted; The rear end of the accommodating groove 12 is an unlocked position, and when the control piece 30 is moved to the unlocked position, the blade 20 or the pressing member 40 is released to be pivotable.

The control piece 30 has a first locking portion 31, a second locking portion 32, and an operating member 33.

Please refer to FIG. 5 and FIG. 6 next. The first locking portion 31 is a recess recessed downward from the control piece 30, and is selectively positioned in the guide groove 14 to abut against the stopper portion 21 of the engaging blade 20 to prevent the blade 20 from being opened. Specifically, when the half knives are in the folded state and the control piece 30 is moved to the locked position, The first locking portion 31 is located at the folding end of the guide groove 14 and abuts against the stopper portion 21 which is also located at the folding end of the guide groove 14, thereby preventing the blade 20 from pivoting open.

When the control piece 30 is moved to the unlocking position, the first locking portion 31 is away from the guiding groove 14, and the stopping portion 21 is released from the first locking portion 31, and the blade 20 can be moved in the guiding groove 14 at this time. . However, in other embodiments, the first locking portion 31 can be convex, and the cutting edge 20 has a groove or a notch that engages with the first locking portion 31, and the purpose of locking the cutting edge 20 can also be achieved.

Please refer to FIG. 7 and FIG. 8 next. The second locking portion 32 of the control piece 30 protrudes upward from the control piece 30 and selectively abuts against the pressing portion 42, so that the pressing member 40 cannot be pivoted to prevent the blade 20 from being folded. Specifically, when the control piece 30 is moved to the locking position, the second locking portion 32 is moved to be located below the pressing portion 42. At this time, if the pressing member 40 is pressed, the second locking portion 32 is administered. The pressing portion 42 on the pressing member 40 reacts with the pressing force, so that the pressing member 40 cannot be pressed. In other words, the pressing member 40 pivots toward the direction in which the elastic member 50 is compressed, and the second abutting portion 41 remains abutted against the first abutting portion 22.

On the contrary, when the control piece 30 is moved to the unlocked position, the pressing portion 42 is not supported by the second locking portion 32, so that the pressing member 40 can be depressed and the pressing member 40 can be pivoted. In other words, when the semi-elawing knife is in the open state, when the control piece 30 is in the locking position, the second abutting portion 41 can be prevented from being disengaged from the first abutting portion 22 by preventing the pressing member 40 from pivoting, and the blade edge 20 can be prevented from being pivoted. Turned to the purpose of opening.

The operating member 33 is disposed on one side of the control piece 30 and passes through the through hole 13, and the operating member 33 is movable in the through hole 13 along the length direction of the blade 20. When the operating member 33 moves in the longitudinal direction of the blade 20 in the through hole 13, the driving control piece 30 is entirely moved in the longitudinal direction of the blade 20 in the receiving groove 12. Therefore, the user can control the locking or releasing of the blade 20 through the operating member 33 that passes through the through hole 13. In addition, in other embodiments, the operating member 33 can also be disposed on the upper surface or the lower surface of the control sheet, and can pass through the gap between the first housing 10a and the second housing 10b, and can also be driven by the operating member 33. The purpose of controlling the overall movement of the sheet 30 is as follows.

In addition, in other embodiments, the direction in which the control piece 30 moves can be perpendicular to the longitudinal direction of the blade 20, and the purpose of locking the blade 20 and the pressing member 40 can also be achieved. Accordingly, the extending direction of the through hole 13 is also perpendicular to the longitudinal direction of the blade 20 so that the operation 33 can be moved in the longitudinal direction of the vertical blade 20 and the entire control piece 30 is driven.

In summary, the present invention has an advantage in that, by moving the control piece 30 to the locking position, the second locking portion 32 on the control piece 30 in the open state abuts against the pressing portion 42 fixed to the pressing member 40. In order to lock the pressing member 40, the second abutting portion 41 of the pressing member 40 is held in a state of hooking the first abutting portion 22 of the blade 20, so that the half-knife preventing the open state can be folded. In addition, in the folded state, the first locking portion 31 on the control piece 30 can selectively engage the stopping portion 21 of the blade 20 to lock the blade 20, so that the blade 20 cannot be pivoted, thereby enabling The half-knife that has reached the state of being folded is opened.
