- said longitudinal cradle comprises two rigid sections, each having a first end and a second end, said sections being held substantially parallel to one another by spacers, the first and second ends respectively facing one of the other, the middle part of said sections defining a mean plane.
- the base forming a stop consists of a cradle produced using two rigid metal profiles of circular section kept apart by at least two spacers made of scalloped and toothed sheets intended to hold the shell in position and serving as a stop on one of the sides of the cradle when the blade of the pliers is inserted into the hinge of the shell so as to effect the arching of the shell between the spacers and the blade penetrating into the hinge when said drive means are actuated.
- said first attachment means are formed by the second two ends of said profiles, curved on the same side of said mean plane, towards said first ends of said profiles.
- the rigid metal profiles of circular section kept apart by spacers serving as support, on the other side of the cradle, to the second attachment means constitute a ramp of rounded shape used to position the clamp, or perforation means , so as to achieve the buttressing of the shell between the spacers of the blade penetrating the hinge when said drive means are actuated.
- said abutment is formed of a connecting piece connecting said first ends of said sections and inclined towards said second end.
- the end of the ramp comprising the connecting piece formed by a substantially horizontal sheet metal plate serves both as a spacer and to facilitate the holding in position of the shell on the spacers, the thumb placed on the shell , the other fingers resting on the underside of the sheet metal plate.
- said drive means comprise: means for guiding said blade having a working end and a control end, said first end of the blade forming a point being capable of projecting from said working end and the second end of the blade being capable of projecting from said control end; two branches, each of the first ends of which is articulated on each side of said guide means, capable of pivoting towards one another and towards said control end; and, two links, the first ends of which are pivotally mounted on said second end of the blade and each of the second ends of which is articulated on a branch so that said links form an angle greater than 90 ° with said blade, and a lower angle 180 ° between them.
- said second attachment means consist of two lugs respectively extending said first ends of said two branches in opposite directions from one another so as to project into the periphery of said guide means.
- the clamp, or perforation means comprising the blade and the drive means, consists of two movable branches comprising on each of these branches a lug allowing the branch to rest on the ramp rounded shape of the base.
- the arms of the clamp are inserted and articulated in rotation each along an axis at the level of the pins in the guide means, or yoke, serving as a guide and as a stop for the blade.
- the blade guided in the yoke, comprises the two articulated links on either side of the blade and on each of the arms of the clamp so that when the arms are clamped, said blade moves axially which introduced into the hinge shell enters it forming a corner and causes the opening of the shell.
- said guide means comprise on each side a stop limiting the opening of said two branches.
- the yoke comprises on each side of the blade a stop limiting the opening of the branches of the clamp so that the blade is visible and allows the introduction of the blade in the hinge of the shell.
- said perforation means comprise elastic means capable of separating the two branches from one another.
- a spring resting on the rods and on the end of the yoke, or guide means keeps the branches of the clamp open.
- all the parts constituting the device are metallic made of food-grade stainless steel.
- the device according to the invention uses a cradle to position and maintain the seashell.
- This cradle also serves as a support for pliers with a blade.
- the pliers blade Before positioning the shell on the cradle, the pliers blade is inserted at the hinge of the shell.
- the shell is positioned on the cradle, the lugs of the pliers' branches rest on the ramp of the cradle.
- the wedge blade penetrates into the shell and causes the hinge to yield. It is then enough to grasp the shell with one hand and with the other to keep closed the two branches of the forceps to use the blade to cut the muscle connecting the two shells.
- the shell is opened by the hinge and leaves no debris inside. The effort required is relatively low. There is no risk of injury.
- the device according to the invention responds well to the goals set.
- FIG. 1A is a schematic plan view of the clamp, open branches,
- FIG. 1B shows the clamp, closed branches
- FIG. 2A is a schematic side view of the device according to the invention
- FIG. 2B is a schematic front view of the seashell held on the base without the clamp.
- FIG. 2C is a schematic side view of the device according to the invention according to a particular embodiment.
- Figure 1A is shown according to the schematic plan view the clamp 3 in position 5 open.
- Each of the branches comprises on one side a lower part 5c allowing their gripping and at the other end a lug 5a intended for the attachment of the clamp on the support cradle of the shell.
- the branches are linked together by a yoke 7 consisting of two flanges enclosing above and below the branches, which are articulated in rotation each along an axis 7a further connecting the two flanges of the yoke 7.
- a blade 4 slides between the flanges of the yoke, the movement of the blade is generated by two rods 8 articulated in rotation by a common axis 4a at the level of the blade and by an axis 5b at each branch 5.
- a spring 9 is placed between the yoke 7 and the rods 8 at their common axis 4a. Rear stops 7b limit the movement of the blade 4 and the opening of the branches 5.
- FIG. 1B shows the clamp 3, branches 5 closed, the spring 9 compressed.
- the lower parts 5c of the branches are joined.
- a coating inserts the lower parts 5c of the branches in the manner of the handle of a knife in order to facilitate the maneuvers of the branches 5.
- the blade 4 is in the extended position.
- the amplitude of the movement is of the order of 25 to 30 mm, which is sufficient to yield the hinge.
- the deployed blade measures approximately 60 mm, connecting the two shells, which makes it possible to cut the muscle.
- the device according to the invention is shown in a diagrammatic view 2A from the side, consisting of the cradle forming a base 1 on which the shell 2 is positioned and maintained.
- the shell is supported by two or three spacers 6 holding the two metal sections of circular section apart constituting the cradle forming a base 1.
- a substantially horizontal plate 1c is fixed to a first end 1a of the cradle, at the ends of the profiles serving both as a spacer and facilitating the retention of the shell on the spacers 6.
- the thumb exerts pressure on the shell, and to do this the other fingers rest on the underside of this horizontal plate 1 c.
- the clamp 3 seen in profile shows the total thickness of the clamp consisting of three thicknesses successively from 2 to 3 mm in food-grade stainless steel, the flange of the underside of the yoke 7 with rods 8, the branches 5 provided with the blade 4, the bottom flange of the yoke 7 with links 8.
- the clamp 3 thus formed is inclined by about 30 ° relative to the horizontal plane on which the base 1 rests. This position facilitates the penetration of the blade into the hinge.
- this hinge is not entirely on the approximate axis separating the shell into two parts. It is generally, especially for oysters, deported to the left, the device seen in plan. Consequently, the opening of the shell is facilitated by tilting the clamp about 30 ° and moving the shell slightly to the right. In this position, the pins 5a resting on the ramp 1b of the base make it possible to maintain the arched shell between the blade 4 and the spacers 6. Thus the effort required for the blade to penetrate the shell hinge is reduced.
- Figure 2B is shown in a front view ramp side the seashell held on the base.
- the shell rests on the interposed and indented spacers 6 conforming to the shape of the shell so as to absorb the force exerted by the blade produced by the clamping of the branches 5 of the clamp 3.
- the device according to the invention constituted by the combination of a base 1 and a clamp 3 responds well to the objectives set: ease of use, security and inexpensive.
- FIG. 2C illustrates a particular embodiment of the invention according to which, the cradle constituting the base 1 has in its first end 1a a stop 10, formed of a connecting piece connecting said first ends of said profiles and inclined towards said second end.
- the shell 2 comes to bear against the stop 10 when the blade 4 is driven by the perforation means, or clamp 3 against the joint of the shell 2.
- the position of the blade 4 may be adapted to the shape of the shell, thanks to the curved shape of the second end of the cradle.
- the second attachment means being in abutment against the second curved end, they are easily detached from the cradle as soon as the effort on the drive means ceases.
