La présente invention concerne un dispositif pour bloquer la lame d'un couteau pliant en position ouverte et fermée. En effet l'utilisateur d'un couteau pliant désire pouvoir utiliser cet objet en toute sécurité c'est à dire sans que le couteau ne se referme sur ses doigts. A ce désir s'ajoute celui de pouvoir déverrouiller sa lame de manière simple et rapide. Le blocage est traditionnellement effectué a l'aide de systèmes complexes avec un nombre élevé de pièces. Certains systèmes plus simples sont peu efficaces. Le dispositif selon l'invention permet de remédier à ces deux inconvénients. Le concept de mon couteau repose donc sur deux principes : - un blocage sécurisé de la lame - une seule pièce permettant le verrouillage et le déverrouillage de celle-ci.

REMOVABLY INTERLOCKING BARREL HINGE

Disclosed is a removably interlocking barrel hinge assembly that allows for relative rotation of parts as well as disconnection of the parts. Connectors of the hinge assembly include tabs and recesses that are configured to align and rotate relative to one another. Overlapping of tabs prevents separation in the axial direction, while still allowing for rotation. When disconnection of the parts is desired, the tabs and recesses of the connectors can be aligned, and then pulled apart. The hinge assembly provides in one instance 180 degrees of relative rotation. It may be implemented in a number of devices, including knives and surgical instruments, for example.

Folding knife

A folding knife having a blade and handle further includes a sheath which receives the exposed edge and knife point of the blade in an accommodating slot. A leaf spring in registry with the accommodating slot has a locking face that locks the blade into place and an unlocking face that releases the blade when the handle is rotated about the locked blade, thus allowing the knife to be released from the sheath in an open position. By use of the sheath, the blade can be double edged and can be longer than the handle.

The knife can include a means of one hand opening and closing as well as a means to become latched in, and released from, a fixed position. The four bar linkage knife includes a blade, a handle, and the motion of a four bar linkage to open and close the knife. The four bar knife provides inherent safety because the four bar linkage motion can not fold onto the users hand.

FOLDING BLADE KNIFE WITH FLEXIBLE TENDON AND TENSION SPRING ACTUATION

A folding knife with a handle and blade connected at a axle pin, with a tension spring within the handle pinned to the handle on one end and pinned to a flexible tendon on the opposite end. The flexible tendon is pinned at opposite ends to the spring and the blade at a distance from the blade axle pin. When the blade is folded about the axle pin energy is stored in the tension spring by force transferring from the blade through the flexible tendon to the spring. When the blade is folded a blade release catch blocks the blade from unfolding, and when the user actuates the blade release catch the stored energy in the tension spring is released thus causing the blade to rotate about the axle pin and deploy to the opened position. 1a handle; anda tension spring with a first end and a second end; anda flexible tendon spring with a first end and a second end; anda knife blade; andan axle pin; anda blade release catch;. A folding knife, comprising: 61710777NoneNoneFolding knives can be actuated by various methods of externally applied or internally stored energy. Externally powered folding knives function by the user applying force to actuate the deployment of the blade around an axle pin to its full extended position. Internally powered folding knives use energy stored in a spring mechanism, and typically a catch, button, or stud is pressed which allows the blade to rotate about the axle pin and deploy. In addition to these two methods, a more recent development is the hybrid power system which is often known as the “spring assist” design. This design uses an initial externally powered force by the used, typically on a projection on the side of the blade, to start the deployment of the blade. At a certain point in the rotation about the axle pin the spring overcomes an internal stud or projection that provides resistance, and once past that projection the spring force is applied to the blade and fully deploys the blade without any further force applied externally by the ...
