Cooking knife with two edged parts of only blade

Abstract

 The knife consists of a plastic oblong hollow inside shell haft formed by an upper half-shell (1) and a lower half-shell (2) to be jointed with welding line (3). Into said half a blade (5) is provided, articulated on a pin joint (4) passing into the hole (5a) of the blade. Said blade to be alternatively moved by hand till one of the two running ends: a front running end (6a) and a back running end (6b) of the slot (6) provided into the lower half-shell (2). Said manual moving to bring in position, on the front running end (6a) with the balde in total opening, a straight saw-toothed edged part (5b) and, on the back running end (6b) with the blade in partial re-entry into the shell haft, a half-moon shaped with inside bending edged part (5c) coming to complete the blade having the same cutting way of the saw-toothed edged part. The blade (5) to be blocked in position on the running ends by fitting up of a constraint means consists of an iron leaf spring (7) to be supported on one end between the half-shells (1 and 2) and on the other end through an its hook by a lever (8) to be moved on joint (9) and to be started by a push-button (10) through a flatbed body (11) on that the hook (12) of the leaf spring (7) comes to press.

Description

[0001] The invented means consists of a cooking knife with a blade to be moved by hand on a pin joint fixed into the longitudinal of the oblong shell haft. So permitting to alternatively bring said blade with a stable setting, allowing by a spring fitting up of a constraint means then to be disengaged by a push-button for the return, from a position of total opening to be blocked on a running end to an other position of partial re-entry on the second running end so making in position the other edged part. And, while in the total opening' of the blade, a straight saw-toothed edged part is to be used in one way, able to slice farinaceous, fruits and vegetables, in the other position of partial re-entry of the blade into the haft a second half-moon shaped edged part is to be used which complete the same straight edged part with an inside bending particular to be used for peeling, scraping and for carrying away parts from vegetables, fruits or other. It so realized a knife, particular to be used in cooking, characterized by two different edged parts to be alternatively brought in using position so to be used for different necessities. The invented knife consists of a plastic oblong hollow inside shell haft formed by an upper half-shell 1 and a lower half-shell 2 to be joined with welding line 3. Into said haft a blade 5 is provided, articulated on a pin joint 4 passing into the hole 5a of the blade. Said blade to be alternatively moved by hand till one of the two running ends: a front running end 6a and a back running end 6b of the slot 6 provided into the lower half-shell 2.

[0002] Said manual moving to bring in position, on the front running end 6a with the blade in total opening, a straight saw-toothed edged part and, on the back running end 6b with the blade in partial re-entry into the shell haft, a half-moon shaped with inside bending edged part coming to complete the blade having the same cutting way of the saw-toothed edged part. The blade 5 to be blocked in position on the running ends by fitting up of a constraint means consists of an iron leaf spring 7 to be supported on one end between the half-shells 1 and 2 and on the other end through an its hook by a lever 8 to be moved on joint 9. Said lever 8 to be started by a push-button 10 through a flatbed body 11 on that the hook 12 of the leaf spring 7 comes to press. At the reaching of the blade 5 near one of the running ends, owing to the push given in rotation by the rise 5d in the case of the running end 6a or of the counterposed rise 5e in the case of the running end 6b, the arising of the leaf spring 7 is determined and said leaf spring 7 goes in winding till a release blocking to be actuated by fitting of the rise 5d or of the rise 5e into the hole 13 of the leaf spring 7. To bring the blade 5 on the other running end through the push-button 10 the leaf spring 7 is arisen so permitting to the rise 5d or to the other rise 5e to be extracted from the hole 13 of the same leaf spring 7. The invented knife thanks to its oblong shell permits to create an anatomy haft so raising the gripping condition. The invented knife is illustrated in schematic view in the drawings of sheets 1, 2 and 3. In sheet 1 the knife is illustrated in three sectional longitudinal views. In details fig. 1 is view of the knife with the blade 5 setting up on the front running end 6a. Fig. 2 is view of the knife with the blade already disengaged from the from running end 6a thanks to the disengagement of the constraint means actuated through the push-button 10 in lowering. Fig. 3 is view of the knife with the blade setting up on the back running end 6b. In sheet 2 fig. 4 is lateral view of the knife with the blade on the front running end 6a. Fig. 5 is view from the bottom of the knife to show the slot 6. In sheet 3 fig. 6 is top view or the knife with a key 14 with a central small plate 15 to be used alternatively to the push-button 10. Fig. 7 is lateral view of the knife with the blade 5 on the back running end 6b.

Claims

1. Cooking knife with two edged parts of only blade consists of a plastic oblong hollow inside shell haft formed by an upper half-shell (1) and a lower half-shell (2) to be jointed with welding line (3) into which a blade (5) is provided, articulated on a pin joint (4) passing into the hole (5a) of the blade, characterized in that:

- said blade is to be alternatively moved by hand till one of the two running ends: a front running end (6a) and a back running end (6b) of the slot (6) provided into into the lower half-shell (2);

- said manual moving to bring in position, on the front running end (6a) with the blade in total opening, a straight saw-toothed edged part (5b) and, on the back running end (6b) with the bladein partial re-entry into the shell haft, a half-moon shaped with inside bending edged part (5c) coming to complete the blade having the same cutting way of the saw-toothed edged part;

- the blade (5) to be blocked in position on the running ends by fitting up of a constraint means consists of an iron leaf spring (7) to be supported on one end between the half-shells (1 and 2) and on the other end through an its hook by a lever (8) to be moved on joint (9) and to be started by a push-button (10) through a flatbed body (11) on that the hook (12) of the leaf spring (7) comes to press;

- at the reaching of the blade (5) near one of the running ends, owing to the push given in rotation by the one of the rises (5d or 5e) depending of which of the two running ends (6a or 6b) comes to act, the arising of the leaf spring (7) is determined and said leaf spring (7) goes in winding till a release blocking to be actuated by fitting of one of the rises (5d or 5e) into the hole (13) of the leaf spring (7);

- to bring the blade (5) on the other running end through the push-button (10) the leaf spring (7) is arisen so permitting to one of the rises (5d or 5e) to be extracted form the hole (13) of the same leaf spring (7).

2. Cooking knife with two edged parts of only blade, as per claim 1), characterized in that the oblong shell permits to create an anatomy haft so raising the gripping condition.

3. Cooking knife with two edged parts of only blade, as per claim 1), characterized in that in a version the knife provides a key (14) with a central small plate (15) to be used alternatively to the push-button (10).
