Abstract:
An assisted opening knife includes a handle with a pushing key for releasing and locking a blade. The blade is pivotally connected to the handle and has near its rear end a position-limiting post extending into an arcuate position-limiting groove in, and near the front end of, the handle. The assisted opening knife is characterized by the handle having therein a releasing/locking slide plate whose top side is provided with the pushing key and whose front end, a releasing/locking arm movable to a position near one end of the arcuate position-limiting groove. While the blade is stored in the handle, the position-limiting post touches the aforesaid end of the arcuate position-limiting groove and is locked by the releasing/locking arm to prevent the blade from rotation. The blade is rotatable again when the pushing key, exposed from the handle, is pushed and moves the releasing/locking arm away from the aforesaid position.

Claim (Index 1):
An assisted opening knife with a handle provided with a pushing key for releasing and locking a blade, comprising:\n the blade, which has a front end formed with a blade tip and is protrudingly provided with a position-limiting post adjacent to a rear end of the blade; a lower handle portion below the blade; an upper handle portion above the blade, wherein a portion of the upper handle portion that is adjacent to a front end of the upper handle portion and a portion of the lower handle portion that is adjacent to a front end of the lower handle portion are pivotally connected by a pivotal connection shaft to a portion of the blade that is adjacent to the rear end of the blade such that the upper handle portion and the lower handle portion are coupled together to form the handle, to be held in a user's hand, the upper handle portion and the lower handle portion also form a blade storage space therebetween, the blade is rotatable with respect to the upper handle portion and the lower handle portion about an axis defined by the pivotal connection shaft either into or out of the blade storage space, the upper handle portion is formed with an arcuate position-limiting groove adjacent to the front end of the upper handle portion, and the arcuate position-limiting groove has a circular arc shape centered at the pivotal connection shaft and is so configured and located that a free end of the position-limiting post extends through the arcuate position-limiting groove, that the arcuate position-limiting groove sets limits to rotation of the position-limiting post and hence of the blade, and that the position-limiting post is displaced along the arcuate position-limiting groove in response to rotation of the blade, abuts against a first end of the arcuate position-limiting groove when the blade is completely stored in the blade storage space, and abuts against an opposite second end of the arcuate position-limiting groove when the blade has been rotated out of the blade storage space to a greatest extent; 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 a common lateral side of the upper handle portion and the lower handle portion such that the blade storage space is formed between the upper handle portion and the lower handle portion and corresponds in position to the spacer when the upper handle portion and the lower handle portion are coupled together to form the handle; an upper decorative plate fixed on a top side of the upper handle portion, wherein the upper decorative plate has a top side formed with a key groove adjacent to a front end of the upper decorative plate and has a bottom side concavely provided with a receiving space corresponding in position to the key groove, and the receiving space is in communication the key groove and corresponds in configuration to the arcuate position-limiting groove such that, after extending through the arcuate position-limiting groove, the free end of the position-liming post reaches a corresponding position in the receiving space; a releasing/locking slide plate mounted in the receiving space in a forwardly and rearwardly movable manner, wherein the releasing/locking slide plate has a top side protrudingly provided with the pushing key such that the pushing key is exposed from the top side of the upper decorative plate through the key groove in order to be pushed forward or rearward by the user with a finger or thumb, causing forward or rearward displacement of the releasing/locking slide plate along with the pushing key, and the releasing/locking slide plate has a front end extended with a releasing/locking arm configured to be moved to a position corresponding to the arcuate position-limiting groove such that, when the position-limiting post abuts against the first end of the arcuate position-limiting groove, the releasing/locking arm locks the position-limiting post and thereby brings the position-limiting post and hence the blade into a locked state, in which the position-limiting post together with the blade is not rotatable; a first auxiliary elastic element mounted between the releasing/locking slide plate and the upper handle portion and configured to apply to the releasing/locking slide plate a first elastic force tending to displace the releasing/locking slide plate forward such that, when the blade is rotated to be completely stored in the blade storage space, the first auxiliary elastic element presses the releasing/locking slide plate and thereby displaces the releasing/locking arm, bringing the releasing/locking arm into the locked state, in which the position-limiting post is locked by the releasing/locking arm; and only when the user overcomes the first elastic force by pushing the pushing key rearward with a finger or thumb will the releasing/locking arm be displaceable along with the pushing key to enter an unlocked state, in which the position-limiting post is released from the releasing/locking arm and therefore rotatable together with the blade again; and a main elastic element having a first end fixed in the handle at a position adjacent to a rear end of the handle and an opposite second end extending to a position in the handle that is adjacent to where the handle and the blade are pivotally connected, wherein when the blade is completely stored in the handle, the second end of the main elastic element applies to the blade a storing torque tending to rotate the blade inward of the handle: and when the blade has been rotated out of the handle by a predetermined angle by an external force, the main elastic element applies to the blade an outward spinning torque that rotates the blade further outward of the handle until the blade has been rotated out of the handle to the greatest extent.
