Abstract:
A folding knife configured for safe and rapid disassembly and reassembly includes an upper handle portion having two engaging grooves respectively adjacent to its two ends, and a lower handle portion having an engaging and pivotally connecting shaft and an engaging and locking shaft respectively adjacent to its two ends. The two shafts are engageable in the engaging grooves respectively. A blade is mounted around the engaging and pivotally connecting shaft and rotatable into and out of a space between the handle portions. A pushable locking member is rotatably connected to the engaging and locking shaft and can be pushed to allow or prevent disengagement between the engaging and locking shaft and the corresponding engaging groove. Thus, user only has to push the pushable locking member, the upper handle portion and the blade will be in a detachable from or securely connected to the lower handle portion as a whole.

Claim (Index 1):
A folding knife configured for safe and rapid disassembly and reassembly, comprising:\n an upper handle portion formed with a front engaging groove and a rear engaging groove, wherein the front engaging groove is adjacent to a front end of the upper handle portion, extends toward the front end of the upper handle portion, and has a flared section adjacent to and flaring toward a front end of the front engaging groove; and the rear engaging groove is adjacent to a rear end of the upper handle portion, extends toward the front end of the upper handle portion, and has a flared section adjacent to and flaring toward a front end of the rear engaging groove; a lower handle portion formed with a pivotally-connecting-shaft mounting hole and a locking-shaft mounting hole, wherein the pivotally-connecting-shaft mounting hole is adjacent to a front end of the lower handle portion, and the locking-shaft mounting hole is adjacent to a rear end of the lower handle portion; a spacer mounted between an inner side of the upper handle portion and an inner side of the lower handle portion at a position adjacent to an edge of the upper handle portion and a corresponding edge of the lower handle portion such that a blade storage space is formed between the upper handle portion and the lower handle portion when the upper handle portion and the lower handle portion are connected together to form a handle; an engaging and pivotally connecting shaft having an end fixed on the inner side of the lower handle portion at a position corresponding to the pivotally-connecting-shaft mounting hole, the engaging and pivotally connecting shaft having an opposite second end circumferentially and concavely provided with a first engaging recess, wherein the first engaging recess is adjacent to an end edge of the second end of the engaging and pivotally connecting shaft and matches the front engaging groove of the upper handle portion in configuration such that the engaging and pivotally connecting shaft is engageable with the front engaging groove through the first engaging recess to thereby connect the upper handle portion and the lower handle portion together as the handle and form the blade storage space between the upper handle portion and the lower handle portion; an engaging and locking shaft having a first end rotatably mounted on the inner side of the lower handle portion at a position corresponding to the locking-shaft mounting hole, the engaging and locking shaft having an opposite second end circumferentially and concavely provided with a second engaging recess, wherein the second engaging recess is adjacent to an end edge of the second end of the engaging and locking shaft and matches the rear engaging groove of the upper handle portion in configuration such that the engaging and locking shaft is engageable with the rear engaging groove through the second engaging recess to thereby connect the upper handle portion and the lower handle portion together as the handle and form the blade storage space between the upper handle portion and the lower handle portion; a blade having a front end formed with a blade tip, the blade being formed with a pivotally connecting hole adjacent to a rear end of the blade, wherein the pivotally connecting hole matches the engaging and pivotally connecting shaft in configuration so as to be mounted around a periphery of the engaging and pivotally connecting shaft, thereby allowing the blade to be connected with the upper handle portion and the lower handle portion and be rotated with respect to the upper handle portion and the lower handle portion about an axis defined by the engaging and pivotally connecting shaft either into or out of the blade storage space; and a pushable locking member having a first end and a second end, wherein the first end of the pushable locking member is rotatably mounted between the upper handle portion and the lower handle portion, or on the lower handle portion, at a position adjacent to the rear ends of the upper handle portion and of the lower handle portion and is connected to the first end of the engaging and locking shaft, and the second end of the pushable locking member extends out of the blade storage space and is configured to be pushed by a finger of a user in order to rotate the engaging and locking shaft into a released mode, in which the engaging and locking shaft is disengageable from the rear engaging groove, or a locked mode, in which the engaging and locking shaft is not disengageable from the rear engaging groove; wherein the upper handle portion, the spacer, the blade, and the lower handle portion are put together to form the folding knife by: laying the lower handle portion flat such that the second end of the engaging and pivotally connecting shaft and the second end of the engaging and locking shaft face upward; pushing the pushable locking member until the engaging and locking shaft enters the released mode; placing the spacer on the inner side of the lower handle portion at the position adjacent to the edge of the lower handle portion; mounting the pivotally connecting hole of the blade around the periphery of the engaging and pivotally connecting shaft; bringing the front engaging groove and the rear engaging groove of the upper handle portion into alignment with the second end of the engaging and pivotally connecting shaft and the second end of the engaging and locking shaft respectively; pushing the upper handle portion toward the front end thereof such that the first engaging recess and the second engaging recess are engaged with the front engaging groove and the rear engaging groove respectively, thereby connecting the upper handle portion, the spacer, the blade, and the lower handle portion together as the folding knife, with the blade storage space formed between the upper handle portion and the lower handle portion; and pushing the pushable locking member until the engaging and locking shaft enters the locked mode, thereby ensuring secure pivotal connection between the blade, the upper handle portion, and the lower handle portion, allowing the blade to be rotated stably with respect to the upper handle portion and the lower handle portion about the axis defined by the engaging and pivotally connecting shaft either into or out of the blade storage space.
