Definitions
- the present invention relates to a magnetic cover gripping member for kitchen utensil, for example for a saucepan.
- a lid of the type comprising a cover adapted to cover the culinary article and a removable gripping member attached to the cover by the action of a magnet on a magnetizable piece.
- the determination of the power of the magnet is problematic: if it is too weak, the fastening of the cover to the gripping member may have failures, and if it is too important, it may be difficult for the user to disengage the hood of the gripping member.
- the power of the magnet in order to be able to separate the gripping member, the user must exert a traction force on the gripping member and a bearing force on the hood, which limits this handling when the lid is hot.
- the present invention aims to overcome the aforementioned drawbacks.
- the gripping member of the cover of the above-mentioned type comprises a base and an operating member movable with respect to the base between a magnetization position in which the force exerted by the magnet on the magnetizable piece makes it possible to gripping member hood, and an insulation position in which this force is insufficient to allow the fastening of the gripping member hood.
- FIG. 1 is a sectional view of a gripping member according to a first embodiment
- FIG. 2 is a sectional view of a gripping member according to a second embodiment
- FIG. 3 is a cutaway perspective view of the gripping member according to the second embodiment
- FIG. 4 is a perspective view of a gripping member according to a third embodiment
- FIG. 5 is an exploded perspective view of the gripping member according to the third embodiment
- FIG. 6 is a sectional view of the gripping member according to the third embodiment along the line VI-VI of FIG. 4,
- FIG. 7 is a sectional view of a gripping member according to a fourth embodiment.
- Figure 8 is an exploded perspective view of the gripping member according to the fourth embodiment.
- a cookware cover typically comprises, on the one hand, a hood which is adapted to cover the cooking utensil and, on the other hand, a gripping member 1 which is adapted to facilitate the gripping of the lid by a user.
- the cover comprises, firstly, a magnet 2 which is carried by the gripping member 1, and secondly, a magnetizable piece which is carried by the hood, allowing and the gripping member 1 to be removably attached to the hood by the action of the magnet 2 on the magnetizable piece.
- the gripping member 1 comprises a base 3 and an operating member 4-
- the base 3 forms the body of the gripping member 1 and allows the user to grasp the latter (as well as the cover when he is united).
- the operating member 4 is mobile relative to the base 3 and it allows the user to separate the gripping member 1 of the cover.
- the operating member 4 is movable between a magnetization position in which the force exerted by the magnet 2 on the magnetizable piece allows the attachment of the gripping member 1 to the cover, and an insulation position in which this force is insufficient to allow the attachment of the gripping member 1 to the cover (and thus allows the separation of these two parts).
- the gripping member 1 comprises a return member 5 (in this case a spring 5) urging the operating member 4 in its magnetization position. Therefore, in the four embodiments, the user must drive the operating member 4 from its magnetization position to its release position, and in the fourth embodiment, it must also drive the actuator member. maneuver 4 from its release position to its magnetization position. As can be seen in FIG. 1, in the first embodiment, the magnet 2 is carried by the base 3.
- the base 3 comprises a bottom wall 6 which faces the hood when the gripping member 1 is attached thereto and to which the magnet 2 is fixed by a screw 7.
- the base 3 also comprises a " central column 8 which makes protruding substantially perpendicularly from the bottom wall 6 and in which is made the receiving hole of the screw 7.
- the base 3 also comprises a peripheral wall 9 of substantially cylindrical shape and which projects substantially perpendicular to the wall background 6.
- the bottom wall 6, the central column 8 and the peripheral wall 9 define a housing 10 for, on the one hand, the operating member 4 which is formed by a push button 4 whose upper wall 11 carries the control surface manually, and on the other hand, the spring 5 which extends between the bottom wall 6 of the base 3 and the upper wall 11 of the operating member 4.
- the operating member 4 is slidably mounted in the housing in the direction defined by the central column 8.
- the operating member 4 comprises an abutment member 12 (in this case a tab 12) which extends along the peripheral wall 9 of the base 3 from the upper wall 11, and passes through the bottom wall 6 of the base 3 at an opening 13.
- the abutment member 12 is sufficiently long so that its free end 14 abuts against a bearing surface carried by the cover when the operating member 4 moves from its position of magnetization at its release position, and separates the base 3 of the cover (and therefore the magnet 2 of the magnetizable piece) when the operating member 4 is in its release position.
- the displacement of the operating member 4 from one to the other of its positions causes a change in the distance separating the magnet 2 from the magnetizable piece (and therefore a modification of the intensity of the magnetic force exerted on the magnetizable piece).
- the magnet 2 is carried by a stud 15 which is mounted to move relative to the base 3 and which is driven by the actuating member 4 between a magnetization position in which the operating member 4 is in its magnetization position, and a release position in which the force exerted by the magnet 2 on the magnetizable piece is insufficient to allow the fastening of the member gripping 1 to the hood.
- the base 3 comprises a peripheral wall 9 of substantially cylindrical shape and an inner annular shoulder 16 which extends substantially perpendicular to the axis of revolution of the peripheral wall 9. Furthermore, the inner annular shoulder 16 comprises an opening 17.
- the peripheral wall 9 and the inner annular shoulder 16 define a housing 18 for, on the one hand, the stud 15 which extends into the base 3 and passes through
- the stud 15 comprises a central column 19 which passes through the opening 17 and defines its direction of translation in the base 3.
- the central column 19 comprises a lower end 20 to which the magnet 2 is fixed by a screw 21 screwed into a housing carried by the central column 19.
- the stud 15 also comprises an outer shoulder 22 which is adapted to abut against the inner annular shoulder 16 when the operating member 4 is in its magnetization position and thus to define the position of magnetization of the stud 15.
- the inner annular shoulder 16 and the peripheral wall 9 of the base 3 define a first housing 23 which is situated on a first side of the inner annular shoulder 16 and in which are housed the lower end 20 and the magnet 2.
- the inner annular shoulder 16 and the peripheral wall 9 of the base 3 define a second housing 24 which is disposed on the other side of the inner annular shoulder 16 and in which is housed the outer shoulder 22 of the stud 15.
- the spring 5 is housed in the first housing 23, it extends between the magnet 2 and the inner annular shoulder 16 of the base 3 and it biases the stud 15 in its magnetization position.
- the spring 5 is housed in the second housing 24, it extends between a cover 25 which is secured to the base 3 by means of screws 26, and the upper end 27 of the stud 15 and it solicits the stud 15 in its magnetization position.
- the stud 15 also comprises a cam surface 28 which, in the second and third embodiments, is disposed in the second housing 24, and which is adapted to cooperate with the operating member 4 connected to the base 3 so that, when the operating member 4 moves from its magnetization position to its release position, it drives the stud 15 from its magnetization position to its release position.
- the operating member 4 is formed by two elements 4 which are pivotally mounted relative to the base 3 along an axis substantially parallel to the axis of revolution of the peripheral wall 9 of the base 3.
- Each element 4 is connected to the base 3 by a shaft 29 which defines the pivot axis and is shaped so as to bear against the cam surface 28. Therefore, in the two embodiments mentioned above, the approximation of the two elements 4 of the other by pivoting about their pivot axis causes translation of the pad 15.
- the base 3 comprises in its peripheral wall 9 a guide opening 30 which imposes their movements to the two elements 4 and which therefore, limits the torsional forces at the level of the shafts 29 and thus makes it possible to effectively transmit the movement to the pad 15.
- the displacement of the operating member 4 from one to the other of its positions causes a change in the distance separating the magnet 2 from the magnetizable piece (and therefore a change in the intensity of the magnetic force exerted on the magnetizable piece).
- each element 4 is formed by a rod 4, the shaft 29 associated therewith being disposed in an anchoring cavity 31 made in the peripheral wall 9 and disposed substantially opposite the guide opening 30 relative to the axis of revolution of the base 3.
- each element 4 is formed by a fin 32 which is carried by an arc 33.
- the arc 33 eccentric with respect to the axis of pivoting of the element 4, is adapted to abut against the cam surface 28 of the pad 15.
- the shafts 29 are carried by the inner annular shoulder 16.
- the magnet 2 is carried by the operating member 4.
- the base 3 comprises a bottom wall 6 which faces the hood when the gripping member 1 is fixed thereto, and a peripheral wall 9 of substantially cylindrical shape projecting substantially perpendicularly from the bottom wall 6.
- the base 3 also comprises two transmission members 34 which are made of a magnetizable material, such as mild steel. Each transmission member 34 extends along the peripheral wall 9, and passes through the bottom wall 6 at an opening 35 so as to be in contact or in close proximity to the magnetizable piece carried by the cover.
- the interior of the base 3 defines a housing 36 for, on the one hand, the operating member 4 rotatably mounted thereon along the axis of revolution of the peripheral wall 9, and, on the other hand, the magnet 2 which is fixed to the operating member 4.
- the housing 36 is defined axially by the bottom wall 6 and magnetically isolates the magnet 2 from the magnetizable piece carried by the cover.
- the housing 36 is delimited radially, on the one hand, by the two transmission members 34, and, on the other hand, by the two portions of the peripheral wall 9 which separate the two transmission members 34 from one of the other.
- the magnet 2 of cylindrical shape complementary to the shape of the housing 36 is polarized so that when the operating member 4 is in its position of magnetization, each pole 37, 38 of the magnet 2 is in contact with a single transmission member 34 so that the latter transmit to the magnetizable element the magnetic flux generated by the magnet 2, and, when the operating member 4 is in its release position, each pole 37, 38 of the magnet 2 is in contact with the two transmission members 34 to short-circuit the magnetic circuit.
- the operating member 4 moves from a magnetization position to a release position and a release position to a magnetization position by a quarter-turn rotation.
- the displacement of the operating member 4 from one to the other of its positions causes a change in the flow of the magnetic flux.
- the gripping member 1 comprises only one magnet 2. Many modifications can be made to the described embodiments.
- the magnet 2 could be carried by the hood and the magnetizable piece by the gripping member 1.
- the cam surface 25, instead of being carried by the stud 15, could be carried by the base 3, the operating member 4 then being connected to the stud 15.
- the two transmission members 31, 32 instead of extending angularly each on almost one half of a cylinder, could extend over a much smaller angular sector so that when the maneuvering member 4 would move into its release position, each pole of the magnet 2 would be in contact with any of the two transmission members 31, 32, which would also bypass the magnetic circuit. It would also be possible for the gripping member to comprise several magnets which would then all be totally integral in movement with one another.
