Problems solved by technology

and having to grip these knives differently depending on whether someone is moving the blade or adjusting it can lead to an overly complicated process
Finally, these clumsy movements likely increase the risk of accidents when the blades are opened

Embodiment Construction

[0008] The description provided above mainly deals with figure 1 and figure 2 . The body of the knife includes a sheath 1 at the front and a handle 2 at the rear, and the sheath and the handle are connected together by screws. A common type of blade 3 with a beveled leading edge including a tip 4 is located in a sheath 1 in which it slides. The sheath 1 includes a removable capotage 5 which is used to create an opening in the sheath to provide access to the blade 3 and to replace the blade. In order to make a part of the blade 3 visible in all cases, a window-like opening 6 is formed through the cover 5 to check the position of the blade by means of the position of the guide marks 7 or other orientation marks.

[0009] A patte 8 is fixed to the sheath 1, on which a gripping bar 9 is hinged by means of an axis 10, the direction of which is transverse. The bracket 8 and the grip bar 9 are located above the sheath 1 and the handle 2 . The grip bar 9 is hinged to the shaft 1...

Abstract

The knife has a handle (2) attached at the rear of a sheath (1), and a blade (3) sliding in the sheath in a manner to completely retract in the sheath or to exceed to the front of the sheath. A blade actuating system has a trigger (11) that is movable under the handle, and a rod connects the trigger to the blade. A hand grip bar (9) of the system is articulated at the sheath by an axle (10), and the trigger comprises a return spring (13).

Description

technical field [0001] The subject of the invention is a knife with a telescopic blade ("telescopic cutting knife") adapted to work in special situations, such as working in harsh environments, where a direct grasp of the tool is not possible. Background technique [0002] Working in harsh environments is accomplished with a glove box, where the operator inserts his (or her) arms into a wall with a master and slave arm that mimics the operator's motion on the other side of the protective wall. remote control machine. The operator cannot achieve complete freedom of movement and does not feel the same sensations as he would feel under normal working conditions, thus reducing dexterity. As a result, many tasks become difficult to perform, wherein, in the application considered here with regard to telescoping knives, the actions of opening and retracting the blade, and locking the blade at a selected position are usually accomplished by manipulating a small mechanism on the kni...
