20080276462 | Foldable knife - A foldable knife includes a knife handle having a first end pivotally connected with a pivot and a blade having a first end pivotally connected to the pivot. An elastic member is pivotably received in the knife handle, and has a first end extended to a portion of the blade adjacent to the pivot, and a second end extended away from the pivot and toward a second end of the knife handle. A slide member is movably received in the knife handle. When the blade is completely received in the knife handle and the slide member is moved to a position engaged with the second end of the elastic member, the first end of the elastic member is tightly engaged with a portion of the blade adjacent to the pivot for elastically releasing the blade into the knife handle. | 11-13-2008 |
20080276463 | Folding knife - The present invention discloses a folding knife, which comprises a blade pivotally coupled to an end of a knife handle for pivoting out of the knife handle or being received into the knife handle, a resilient bar with an end fixed to another end of the knife handle and another end extended to the blade proximate to the pivotal connecting position, and a push switch installed proximate to the pivotal connecting position with an end extended to a surface of the knife handle and another end passed through the knife handle and against the blade, such that when the push switch is pushed to drive the blade to turn to a predetermined angle, the resilient bar produces a torque to turn the blade out from the knife handle automatically, so that a user simply needs to push the push switch for the control of turning the blade out from the knife handle. | 11-13-2008 |
20080295338 | Folding knife - A folding knife has a handle and a blade. The blade is pivotally coupled to the handle. The handle includes a latch element, a resilient element and a turning element. An end of the resilient element is fixed into the handle. The latch element is pivotally coupled into the handle. An end of the latch element is extended to an end of the blade. Another end of the latch element presses against another end of the resilient element. The resilient element pushes the latch element to turn the blade out from the handle or store the blade completely into the handle. The turning element is pivotally coupled into the handle, such that when a force is exerted to push the latch element towards the resilient element to release the blade, the blade can be movably turned out from the handle or stored into the handle. | 12-04-2008 |
20090013537 | Folding knife - The invention discloses a folding knife having a knife handle and a blade. A pivotal shaft is at an end of the knife handle; a limit slot is inside the knife handle; and a latch element is in the limit slot. The blade is pivotally coupled to the knife handle through the pivotal shaft. The blade includes a protruding pillar corresponding to a latch portion. When the blade is stored into the knife handle, the protruding pillar is fixed between the limit slot and the latch element, and the blade will not pivot out of the knife handle due to shakes or vibrations. If a predetermined force is applied to rotate the blade towards the knife handle, the protruding pillar will rotate in conformity with the blade and push the latch element, so that the protruding pillar is released and rotated with the blade in the limit slot. | 01-15-2009 |
20090126200 | Folding knife having a poking element - A folding knife includes a handle, a blade, a resilient element and a poking element. The blade can be turned into or out from the handle. The resilient element has an end fixed to the handle and another end extended to a position of connecting the handle and the blade. If the blade is stored in the handle, the resilient element produces a torque to turn the blade into the handle. When a force is applied to turn the blade out from the handle, the resilient element produces a torque to pop the blade out from the handle automatically. The poking element is provided for turning the blade. When the blade is in the handle, the poking element presses against the blade, such that if a user pokes an end of the poking element, another end of the poking element turns the blade out from the handle. | 05-21-2009 |
20090183374 | Foldable knife having switch element - A foldable knife comprises a blade having an end pivotally connected to an end of a handle, and a spring having two ends connected to the handle and blade respectively, so that the spring can apply a torque to the blade to rotate the blade out of the handle. A blocking element is provided at an inner portion of the handle. A switch element pivotally connected to the inner portion of the handle has a first end extended out of the handle. When the blade is completely received in the handle, a second end of the switch element bears against the blade. When the user pushes the first end of the switch element, a positioning portion formed on the blocking element is disengaged from an engaging portion formed on the blade, so that the torque of the spring drives the blade to spring out of the handle. | 07-23-2009 |
20090183375 | Folding knife with turning device on knife handle - The present invention discloses a folding knife, which includes a knife handle having a slot; a blade pivotally coupled to the knife handle and turnable into or out from the knife handle; a resilient device fixed to the knife handle and extended to a position proximate to the pivotal connecting position, such that when the blade is stored completely into the knife handle, the resilient device produces a torque to turn the blade into the knife handle, and when the blade is turned to a predetermined angle out of the knife handle, the resilient device produces a torque to turn the blade out from the knife handle; and a turning device, pivotally coupled to the knife handle and having a protruding pillar passed through the slot for securing or releasing the blade as required. | 07-23-2009 |
20090193663 | Folding knife with a hollow handle for fastening an item therein - A folding knife comprises a blade and a handle, wherein the handle is formed by bending a metal sheet into a shape of inverted U-section for clamping an item (e.g., a lighter) therein and comprises a latch formed by punching on one side thereof adjacent to the receiving space in a direction opposite to the receiving space. The blade has one end pivotably secured to one end of the other side of the handle having the latch and the one end of the blade is lockingly fastened by the latch when the blade is in its opened position. The blade is unfastened when a predetermined pressing force is exerted on the latch toward the receiving space such that the blade may pivotably retract onto the other side of the handle. Thus, the folding knife can be mounted with the item (e.g., the lighter) for the functions of cutting and lighting. | 08-06-2009 |
20090217533 | Folding knife with turning device on knife handle - The present invention discloses a folding knife, which includes a knife handle having a slot; a blade pivotally coupled to the knife handle and turnable into or out from the knife handle; a resilient device fixed to the knife handle and extended to a position proximate to the pivotal connecting position, such that when the blade is stored completely into the knife handle, the resilient device produces a torque to turn the blade into the knife handle, and when the blade is turned to a predetermined angle out of the knife handle, the resilient device produces a torque to turn the blade out from the knife handle; and a turning device, pivotally coupled to the knife handle and having a protruding pillar passed through the slot for securing or releasing the blade as required. | 09-03-2009 |
20130067750 | ASSISTED FOLDING KNIFE WITH HANDLE HAVING POKING ELEMENT - The present invention is to provide an assisted folding knife, which includes a handle; a blade having a first end pivotally connected to a first end of the handle; a first resilient element having a first end positioned proximate to a second end of the handle and a second end extending to the pivotally connecting position of the handle and blade, such that when the blade has been rotated out from the handle by a predetermined angle, the first resilient element produces a torque tending to rotate the blade out of the handle; a post fixed on the blade, and exposed outside the handle when the blade is completely received in the handle; and a poking element pivotally provided in the handle and having a first end lying outside rotation of the blade, and a second end pressed against the post when the blade is completely received in the handle. | 03-21-2013 |
