Definitions

• multifunctional pocket knives There is a wide variety of multifunctional pocket knives, most of which are characterized by the following arrangement: they consist of a handle formed of two parallel flanks secured to each other by connecting axes and providing space storage for holding one or more tools or instruments, knife blade, screwdriver, awl, can opener, etc.
• pocket knives appeared later, originally provided with a single cutting blade falling in a housing arranged in the handle; therefore, the blade can only be at best equal to the handle length, but usually slightly less than the latter.
• pocket knives became more and more complex, incorporating several cutting blades and finally other tools or instruments such as a screwdriver, a can opener, a corkscrew or a blade of saw for example.
• the present invention aims precisely to overcome these disadvantages, weaknesses or disadvantages by proposing in particular a pair of scissors having a reduced number of component parts, which facilitates mounting all the same, greater robustness and increased efficiency.
• the invention consists of a multifunctional pocket knife consisting of a handle formed of two integral flanks providing at least one storage space for folding tools each pivoting about the connecting pins arranged at each end of the handle and comprising a pair of scissors consisting of two flat blades each having a cutting edge and pivoting both around a same connecting axis as mentioned above, the pivoting end of each of said blades cooperating with a return spring, said spring ensuring the maintaining, if not blocking, one of the two blades active open position respectively inactive closed, while exerting a sufficient elastic force to keep apart the two blades, once the pair of scissors deployed.
• the invention also relates to a pair of scissors intended to be combined with or incorporated in a pocketknife, consisting of two flat blades each having a cutting edge and both pivoting about a same connecting axis disposed at a end of the handle of said knife, the pivoting end of each of said blades cooperating with a return spring, said spring ensuring the holding, if not the blocking, of one of the two blades in active open position respectively inactive closed, while exercising a elastic force sufficient to keep apart the two blades once the pair of scissors deployed.

• return spring is used to define the spring which ensures the locking of a tool or foldable instrument in the closed position, respectively open during use, the knife blade or screwdriver for example. Such a spring acts essentially by cooperating with the pivoting end of the tool or instrument considered.
• the particularity consists in having only one return spring cooperating, when required, with the pivoting end of each blade of the pair of scissors.
• the trick is also to use the same return spring for another tool, the saw blade for example, in addition to said pair of scissors. This results in a significant gain in terms of manufacturing: one-piece assembly and less handling.
• flat defines, by extension of its general definition (a flat surface on a cylindrical part) an area disposed opposite the cutting edge of each blade, zone on which the pressure will be exerted to bring said blades closer to one another during the cutting operation. This flat can be achieved during the manufacture of said blades or later, for example by abrasion and its contact surface can be both smooth and rough.
• the term "gripping member” defines a tab as generally present on the various tools or conventional instruments of a pocket knife, knife blade, saw, screwdriver, etc., the feature of the invention consisting of an adjacent member a space traversing from side to side the body of the blade emerging from the storage space, a tab according to the terms customary in the art of cutlery.
• the pocket knife 1 consists of a handle 2 formed of two integral flanks 3, 3 'providing at least one storage space 4 for tools each pivoting about the connection axes 5, 5 'disposed at each end of the handle 2.
• the bottom of the storage space 4 consists of a return spring 7 duly fixed between the two sides 3, 3'.
• the pair of scissors 8 consists of two blades 9, 9 'both pivoting about the same connecting axis 5, each through its pivoting end 11, respectively 11'.
• Each of said blades has a cutting edge 10, respectively 10 'along its entire length.
• each of the blades 9, 9 ' has a flat portion 12, respectively 12'; these flats face each other in the closed position.
• the flat portion 12, 12 ' is located on the first half of the corresponding blade, starting from its pivoting end 11, respectively 11', sometimes even at the first third of the blade: this location, reserved to the exercise of manual pressure (fingers) during the cutting operation, will in fact be a compromise between the possibility of exerting sufficient force or cutting pressure and the need to ensure the proper control of the pair chisel in action, if not the knife itself.
• the advantage of the invention lies inter alia in the fact that in one gesture, approximation or closure of the two blades 9 and 9 ', one makes a cut equivalent to the entire length of said blades, and this without having to deploy an extreme force, whereas for a pair of crossed-blade scissors (see eg US D658,964 S) the cut can not exceed half a blade, in practice 2 to 3 cm at best.
• the portion of the blade 9 emerging from the storage space 4 is provided with a gripping member of the tab 13 type adjacent to a space 14 passing through the body of said blade from one side to the other.
• configuration is everything particularly favorable for the gripping of the instrument for its deployment, by a person as right handed as left handed.
• the opening or separation of the blades 9 and 9 ' is controlled by means of a pin 15 disposed on the inner face of the blade 9, in the vicinity of its pivoting end 11 (Fig. 5) this pin 15 cooperates with a recess 16 arranged opposite the latter through the pivoting end 11 'of the blade 9'.
• the stroke of the pin 15 in the space 16 determines the maximum spacing of the blades 9 and 9 'in the deployed position; it is generally of the order of 25 to 30 or even 45 degrees depending on the case.
• a pocket knife takes place as follows: the knife in hand, the user grasps the terminal portion of the blade 9 at the level of the tab 13 and then deploys the pair of blades 9, 9 'to maximum opening. Once this stage is reached, the pivoting end 11 of the blade 9 abuts against the end portion 17 of the return spring 7, which bears on a dedicated location of said pivoting end 11 (see Fig. 7): as an option said blade can also be secured in this position.
• the arrangement of the end end 11 'of said blade 9' is such that during the deployment phase described above, it is permanently supported on the end portion 17 of the return spring 7 mentioned above.
• the return spring 7 thereby permanently exerts a back pressure on the blade 9 'by means of its pivoting end 11'.
• the latter At its progressive approach of the blade 9, in other words during the cutting operation, generated by the pressure exerted by the user on the flats 12 and 12 ', the latter returns said blade 9' to the open position ( active) once released the pressure exerted manually on the flat 12 '.
• the cutting is effected by a pressure exerted simultaneously on each of the flats 12 and 12 '(see Fig. 6).
