Description

PIVOTTING GRIPPING DEVICE

FOR A CULINARY USTENSILE

  The present invention relates to a collapsible gripping device for a cooking utensil, and in particular for a cooking cooking utensil.

  Document US Pat. No. 1,490,568 discloses a gripping device of the extended handle type transversely fixed, by means of a support, to the cap of a cooking utensil and capable of pivoting along a vertical axis defined by a screw. shoulder jointing by simply covering one end of the handle to the support. A locking system allows the user to lock the handle in the use position.

  Such a device makes it possible to obtain a handle of a folding cooking container having a limited number of pieces, but this solution nevertheless has a lack of bending strength at the level of the shoulder screw, as well as a lack of practicality regarding the actuation of the locking system by the user.

  On the other hand, the gripping device of a culinary article having a handle that can rotate and offering greater strength is described in EP 0 247 229. This device, attached to the kitchen utensil via a support, has a hinge by assembling high concentric cylinders, one of which, adjacent to the handle, fits into a deep annular groove of the other, adjacent to the support. This cylinder assembly receives, in the remaining annular cavity, a long rod defining the axis of rotation of the handle. The rod has, at its lower end, two projections, one of which maintains the rod integral in rotation with the handle and the other locks the position of the handle by engaging in a depression of the support cylinder.

  However, this device has many friction surfaces at the cylinder assembly that can hinder rotation after several uses and a lack of practicality regarding the unlocking actuation by the user.

  It is also known from EP 0 809 962, a device for gripping a culinary article comprising a handle that can be folded down and having a limited number of friction surfaces between the handle having an annular projection fitting to a low height in an annular groove of the element fixing the entire device to the utensil, that is to say the support. The axis of rotation of the handle is defined by a pad attached to the support from below and resting against the outside of the handle. This pad receives an accessible actuation button causing the vertical movement of a metal lock pin within the pad and at the grooves of the handle to lock the handle in position.

  While certainly, such a device has less friction when rotating the handle while having good ergonomics of the actuating elements, the bending strength is substantially less with constraints that can be exerted at the base of the pad. In addition, this device has a relatively large total number of parts, many of which are metal, expensive and accessible active parts.

  The object of the present invention is to overcome these disadvantages and to provide a retractable gripping device offering enhanced strength while limiting the friction surfaces.

  Another object of the invention is to easily produce a device that is simple, economical and easy to use.

  These objects are achieved with a gripping device for a cooking utensil comprising a handle pivotally mounted to a support attached to the cap of the cooking utensil provided with a locking mechanism for locking the handle in the use position, thereby the mechanism comprises a locking ring mounted in translation coaxially with the axis of rotation of the handle.

  Such a gripping device makes it possible to reduce the bulk, to improve the compactness and the stacking of the utensils of the same range while offering a solidity and a safety in position of use thanks to the locking device which it has.

  The ring, an element that locks the position of the handle, preferably consists, for reasons of convenience, of molded plastic. As a result, the lock of this device offers a considerable economic advantage in comparison with generally known locking devices that are generally made of metal.

  Advantageously, the axis of rotation of the handle is formed, inter alia, by an annular bulge of the support as well as by the periphery of a stop fixed on the support and the slide lock ring, against the effect of an elastic means. between the support and the stop.

  The contact between the handle and the support is made by a female knuckle of the handle corresponding to a hollow cylinder being taken around a simple lower annular bulge and a simple upper stopper thickness materializing a male knuckle support. As a result, the pivoting of the handle generates a limited number of friction surfaces in contrast to known devices having hinges by assembling high cylinders in connection with large areas. Thanks to a lower number of friction surfaces, the sliding remains pleasant even after many manipulations of the device and the device does not really require the establishment, in the friction zones, generally expensive metal sliding washers.

  The stop is fixed to the support by a screw to be long enough to cross the stop, the ring and insert deep enough into the support. This massive screw entering deeply into the support, also massive piece, and allowing assembly on a high height, provides an advantage of mechanical strength in bending in the dimensions of its pivot axis particularly important when the cap of the utensil is very loaded .

  Usefully, the face of the handle facing the lock ring has at least two depressions, and the lock ring has at least one stud intended to engage alternately, under the action of the elastic means, in one of the recesses of the handle when the handle is in the operating position or in the storage position.

  Such a locking device effectively blocks the handle in the different positions and provides increased safety and strength of the device.

  Preferably, the abutment face, facing the lock ring, has at least one depression, and the stud of the locking ring engages simultaneously in the depression of the abutment and in one of the recesses of the handle under the action of the elastic means.

  A device according to this configuration provides a double locking of the lock consisting of one or more studs of the ring taken from both sides by the recesses of the handle and those of the stop. This double locking provides a safety, reliability and strength of the hinge even more important.

  Advantageously, the support comprises a cylindrical pin having at least one locking tongue in rotation and the locking ring has at least one keyway groove matching the locking tab rotation; or conversely the locking ring has a tongue engaging in a keyway groove of the cylindrical post.

  With a fairly simple means requiring only a modification of the molding of the parts, the lock ring can be locked in rotation by the support, while remaining mobile along the axis of rotation.

  Only the handle is rotatable during pivoting of the device.

  According to another feature of the device, the support comprises a pin having at least one keyway and the stop has at least one key engaging in the keyway groove of the post; or conversely the pin has a key engaging in a keyway groove of the stop.

  This engagement of the abutment vis-à-vis the support allows to correctly orient the stop relative to the support during assembly and simplify it, the stop is not necessarily a symmetrical part.

  Advantageously, the gripping device also comprises a means for actuating the unlocking in rotation of the handle having at least one tooth and the abutment having at least one opening through which the tooth passes so as to actuate the translation of the locking ring. against the effect of the elastic means.

  Such a configuration of the actuation of the unlocking makes it possible to obtain a more adapted ergonomics of the actuating means acting directly on the lock and possibly having larger actuating surfaces.

  In addition, the gripping device hides the fixing screw for better security.

  Advantageously, the lock ring has, on its face facing the abutment, vertical pillars coming into contact with the tooth or teeth of the actuating means.

  Such an actuating device has only relatively simple plastic parts of realization offering an economic and hygienic advantage.

  Advantageously, the tooth or teeth of the actuating means have at least one lumen, and the abutment has at least one indexing finger inserted in the lumen at its aperture (s) so as to retain the means of actuation vis-à-vis the stop.

  Such a device allows the stopper to retain the actuating element while leaving it movable vertically along the axis of rotation and without using additional parts.

  Advantageously, the handle has, at its inner wall opposite its axis of rotation, a rib in an arc having two ends, and the stop has a lug against which one end of the arcuate rib comes into stop when the handle is in the use position, or in the storage position.

  This device allows to limit the rotation of the handle once in position, this feature offers more convenience from the point of view of use, the stop positions corresponding to the final positions in which the handle will be locked.

  The aims, aspects and advantages of the present invention will be better understood from the description given below of a particular embodiment of the invention presented by way of non-limiting example, with reference to the accompanying drawings in which: Figure 1 is a perspective view of the gripper in the work position having undergone partial cutting; Figure 2 is a view of the exploded components of the gripper in perspective; Figure 3 is a bottom view in perspective of the end of the handle in contact with the support; Figure 4 is a side perspective view of the abutment.

  Only the elements necessary for the understanding of the invention have been represented. To facilitate the reading of the drawings, the same elements bear the same references from one figure to another.

  This gripping device comprises a support 2 fixed to the cap of a kitchen utensil on which is pivotally mounted a handle 50 which is locked in the working position, transversely to the edge of the cap, or in the storage position, tangential to the edge, by a locking mechanism comprising a lock ring 40 actuated by an actuating button 90 through a stop 70. (See Figures 1 and 2).

  The support 2 allows the attachment of the entire gripping device to the kitchen utensil; the support 2 is a bent element comprising a horizontal portion and a vertical portion approximately 90 of the horizontal portion. The horizontal part is traversed through and through by a through hole 4 of horizontal axis allowing the passage of a fixing screw, not shown in the figures, so as to bind the support 2 to the cap of the kitchen utensil .

  At the end of its horizontal portion not linked to the vertical part, the support 2 has a narrowing 6 of its wall for receiving externally a firewall 30 by interlocking, the assembly forming a continuity at their outer walls. The firewall 30 constitutes an intermediate element of decoration and thermal protection of the handle 50 between the support 2 and the cap of the kitchen utensil.

  The vertical part of the support 2 is composed of a base cylinder 8 whose upper end forms an upper plate. This plate has an annular bulge 12, of diameter less than the diameter of the base cylinder 8, centered on the axis of the base cylinder 8, and a vertical cylindrical stud 14 coaxial with the base cylinder 8 and of which the outside diameter is smaller than the inside diameter of the annular bulge 12. This common axis corresponds to the axis of rotation of the handle 50 opposite the support 2.

  An annular groove 16 is formed between the inner diameter of the annular bulge 12 and the outside of the cylindrical stud 14; the bottom of this annular groove 16 corresponds approximately to the level of the upper plate of the base cylinder 8.

  The vertical part of the support 2 comprises a threaded blind hole 18, centered on the axis of rotation, starting at the base cylinder 8 of the support 2 and passing right through the cylindrical stud 14. This threaded blind hole 18 is intended to receive a threaded fixing screw 20.

  The cylindrical stud 14 has, at its outer lateral wall, two diametrically opposite vertical locking tongues 22, starting at the lowest point of the cylindrical stud 14 and having a height less than that of the tenon. The two tongues 22 for locking in rotation are symmetrical with respect to the longitudinal median plane of the support.

  The cylindrical stud 14 also comprises, at its outer lateral wall, a rectangular keying groove 24 beginning at the upper section of the cylindrical stud 14, and whose height is less than that of the cylindrical stud 14. The keyway groove rectangular 24 is in the longitudinal median plane of the opposite side of the cap relative to the axis of rotation.

  The locking mechanism of the handle 50 relative to the support 2 comprises a locking ring 40.

  This lock ring 40 is a hollow cylindrical piece of small thickness whose outer diameter corresponds to the outside diameter of the annular bulge 12 of the upper plate of the support 2 and whose diameter of the annular cavity approximately corresponds to the outside diameter of the cylindrical post 14 of the support 2 .

  The lock ring 40 is placed above the support 2 by means of a helical spring 32 bearing at the level of the annular groove 16 formed at the top plate of the support 2. Once the device is mounted, the lock ring 40 is crossed by the cylindrical pin 14 of the support 2.

  The locking ring 40 comprises, at its annular cavity, two keying grooves 42 of rectangular shape, diametrically opposite, indexing at the two tongues 22 of rotation locking located at the cylindrical pin 14 of the support 2, in order to lock the locking ring 40 in rotation while leaving it mobile in vertical translation.

  The lock ring 40 has, at its upper face, two vertical conical studs 44, diametrically opposite and adjacent to the keying grooves 42 and three vertical pillars 46, adjacent to the annular cavity of the locking ring 40, having a section approximately rectangular and being of a height greater than the conical studs 44. These three vertical pillars 46 are approximately equidistant, one of them is located in a plane perpendicular to that containing the two conical studs 44 and containing the axis of rotation and must be placed on the side of the cap with respect to the axis of rotation.

  The gripping device also comprises the handle 50 mounted pivotally relative to the support 2. The handle 50 consists of an extended portion 52 transversely designed to be held by hand and a hollow cylinder 54 centered on the axis of rotation of the handle 50. The outer wall of the hollow cylinder 54 is slightly flared upwards. The outer diameter of the lower section of the hollow cylinder 54 is equal to the diameter of the upper plate of the support 2 so as to obtain continuity of the walls once the device is assembled. The diameter of the annular cavity at the lower section of the hollow cylinder 54 is slightly greater than that of the annular bulge 12 of the support 2.

  Thus, the upper plate of the support 2 and its annular bulge 12 form a hinge with the hollow cylinder 54 of the handle 50, the annular bulge 12 being the male knuckle and the hollow cylinder 54 of the handle 50, the female knuckle.

  The hollow cylinder 54 has a middle ring 56 at its annular cavity, at a distance from its upper and lower ends, and adjacent to the inner wall of the hollow cylinder 54. The inner diameter of this middle ring 56 is very slightly greater than the diameter. that would constitute an adjacent circle externally to the three vertical pillars 46 of the lock ring 40, so as to let the upper part of these three vertical pillars 46 pass through the middle ring 56.

  The middle crown 56 has, at its lower face, two pairs of depressions 58, illustrated in FIG. 3, intended to receive alternately, depending on the position of the handle 50, the two conical studs 44 of the lock ring 40. These depressions 58 are in the form of a cone partially truncated vertically and are adjacent to the opening of the middle ring 56. These recesses 58 make it possible to lock the handle 50 in position relative to the support 2 by the engagement of the conical studs. 44.

  Two of these recesses 58 are symmetrical with respect to the longitudinal median plane to the handle 50 and containing the axis of rotation. They correspond to the position of the conical studs 44 when the handle 50 is perpendicular to the edge of the container, that is to say in the position of use of the utensil.

  Two other recesses 58 diametrically opposite and in the median plane, correspond to the position of the conical studs 44 of the lock ring 40 when the handle 50 is folded towards the wall of the utensil, that is to say in the storage position.

  The middle crown 56 also has, at the upper face level, a square profile rib 60 forming an arc adjacent to the inner wall of the hollow cylinder 54 of the handle 50. The function of the square profile rib 60 will be described later.

  The handle 50 is the only element of the device that can pivot, its axis of rotation is formed, inter alia, by the annular bulge 12 of the support 2 and 15 by the periphery 77 of a stop 70 firmly fixed on the support 2.

  Referring to Figures 2 and 4, the stop 70 is formed of an inner cylinder 72 bordered by three sectors of cylindrical ring 74 equidistant surmounted by an outer plate 76 having openings 78 to the rights of the spaces between the sectors.

  The inner cylinder 72 of the abutment 70 is centered on the axis of rotation of the handle 50, it passes at its inner cavity the fixing screw 20 of the stop 70 to the support 2. This inner cylinder 72 has for diameter outside the inner diameter of the cylindrical ring 74 which is adjacent thereto.

  The three independent cylindrical crown sectors 74 form a virtual cylindrical crown whose height is less than the height of the vertical pillars 46 of the lock ring 40 and greater than the height of the conical studs 44 of the lock ring 40. The spaces between these three sectors define three openings 78 of the same dimensions, of almost rectangular sections, crossing the stop 70 from one side to the other. Two of the cylindrical ring sectors 74 define a circular arc of the same length; the third defines an arc of a circle of shorter length than that of the two other sectors.

  The virtual cylindrical crown is surmounted by the outer plate 76 whose outer diameter is equal to the diameter of the annular cavity of the hollow cylinder 54 of the handle 50 at its upper end thus constituting the upper part of the hinge pin axis of rotation. the handle 50. The lower face of this outer plate 76 is in contact with the upper face of the middle ring 56 of the hollow cylinder 54 of the handle 50.

  The two sectors of cylindrical ring 74 of the same length have, at their external lateral walls, cavities 80 in the form of cone portions intended to receive the conical studs 44 of the locking ring 40. These recesses 80 are diametrically opposed such that are the conical studs 44.

  The openings 78 between the cylindrical ring sectors 74 leave the passage to the vertical pillars 46 of the lock ring 40.

  The third sector of cylindrical ring 74 has, at the lowest point of its internal cavity, a key 82 of rectangular section engaging in the rectangular keying groove 24 of the cylindrical post 14 of the support 2 so that the stop 70 is correctly oriented relative to the support 2 (see Figure 4). Thus, the stop 70 is fixed relative to the support 2, both vertically, by the fixing screw 20 pressing it against the cylindrical pin 14 of the support 2, and in rotation, by the key 82 engaging in the groove of rectangular keying 24 of the cylindrical post 14 of the support 2. It is in contact with the locking ring 40 locked in rotation but which remains mobile in vertical translation along the axis of rotation.

  The outer plate 76 of the abutment 70 has, on its outer edge, in the plane of the outer plate 76, a stop lug 84 defining a portion of a ring of diameter slightly greater than the diameter of the outer plate 76.

  During rotation of the handle 50, the arcuate rib 60 of the middle ring 56 of the handle 50 abuts the stop lug 84, the stop 70 being fixed relative to the support 2.

  The stop 70 has, in its openings 78, indexing fingers 86. The function of these indexing fingers 86 will be described later.

  The gripping device also comprises an actuating means for releasing the handle 50 in rotation, this actuating means consists of an actuating button 90 in the form of a disc.

  The actuating button 90 fitting into the annular cavity of the hollow cylinder 54 of the handle 50 at its upper part, the actuating button 90 is a disc having a diameter smaller than that of the annular cavity mentioned above. This disk has, on its underside, three equidistant hollow teeth 92, centered on the axis of rotation and at a distance from the edge of the disk. These hollow teeth 92 have a rectangular shape and each have a rectangular light 94.

  The actuating button 90 is placed in the space of the cavity of the hollow cylinder 54, above the stop 70 and is connected thereto by the engagement of the indexing fingers 86 of the stop 70 in the light rectangular 94 hollow teeth 92.

  The components are mounted relative to each other in the order from the bottom upwards presented in the exploded view of FIG. 2. The mounting of the gripping device is quite simple compared to certain devices known from the prior art.

  First, the support 2 is mounted by a fixing screw, not shown placed, horizontally and through the firewall 30 to the outer wall of the container of the cooking utensil.

  Then, the helical spring 32 is placed in the annular groove 16 of the upper plate of the support 2.

  The lock ring 40 is then placed on the helical spring 32 around the cylindrical stud 14 of the support 2 so that the keying grooves 42 of the lock ring 40 are positioned around the tongues 22 of the cylindrical stud 14 for locking the ring latch 40 in rotation vis-à-vis the support 2 while leaving it mobile vertically.

  The handle 50 is installed resting on the support 2: the lower edges of the hollow cylinder 54 are in contact with the upper plate of the base cylinder 8 of the support 2.

  The conical studs 44 of the lock ring 40 are positioned at the recesses 58 in the form of a cone portion of the middle ring 56 of the handle 50.

  Then, the stop 70 is positioned so that its key 82 is placed at the level of the rectangular keying groove 24 of the cylindrical post 14 of the support 2. It is screwed by the fixing screw 20 whose length allows it to cross from one end to the stop 70, the handle 50, the lock ring 40, the spring 32, the cylindrical stud 14 and to end at the base cylinder 8 of the support 2.

  It can be seen that the handle 50 is held in rotation at the cap of the kitchen utensil, on the one hand, at the level of the annular bulge 12 and, on the other hand, at the circular periphery 77 of the abutment 70, firmly screwed. in the cylindrical stud 14. The bending strength of this hinge is particularly strong, which is very important especially when it is desired to place heavy loads in the cap and carry the kitchen utensil by the mere manipulation of the handle .

  After placing the aforementioned elements, the actuating button 90 is put in place above the abutment 70, in the remaining space of the hollow cylinder 54 of the handle 50. The actuating button 90 is retained by the engagement indexing fingers 86 of the abutment 70 at the rectangular lights 94 of the hollow teeth 92 of the actuating button 90.

  During the use of the gripping device, the support 2, the firewall 30 and the attachment screw to the utensil, the stop 70 and the fixing screw 20 of the stop 70 to the support 2 remain fixed in rotation and in translation relative to the utensil.

  The lock ring 40 and the actuating button 90 are locked in rotation but are movable in vertical translation along the axis of rotation.

  The only movable element in rotation is the handle 50, however, it is fixed vertically.

  When the user wants to fold the handle 50 from the use position to the storage position, it presses vertically on the actuating button 90. Then, the hollow teeth 92 of the actuating button 90, passing through the stop 70, move the vertical pillars 46 of the lock ring 40 and generate a vertical downward translation of the lock ring 40. As a result, the conical studs 44 of the lock ring 40 are disengaged from the conical recesses 58 of the handle 50 and recesses 80 of the stop 70 which locked the position of the handle 50. The handle 50 is unlocked and is pivotable from the use position to a storage position until the abutment lug 84 of the stop 70 touches one end of the arcuate rib 60 of the handle 50. The handle 50 rotates 105 relative to the initial position.

  Once in the storage position, the conical studs 44 of the lock ring 40 are found opposite the other two recesses 58 of the middle ring 56 of the handle 50. Then, the coil spring 32, compressed during the lowering of the button actuating 90, raises the lock ring 40 and its conical studs 44 at the second pair of recesses 58. The lock ring 40 up, the vertical pillars 46 in contact with the hollow teeth 92 of the actuating button 90, raise the actuating button 90 to its initial position. Thus, the handle 50 is locked in position until the next actuation button 90 is actuated.

  To facilitate assembly, it is necessary to place the elements in an intermediate position to have the ring 40 in the low position, which releases a clearance for the passage of the hollow teeth 92 of the button 90.

  The invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

  Alternatively, one could also consider a gripping device for a folding kitchen utensil, relative to the position of use, tangentially to the cap of the kitchen utensil or above the cap of the utensil of cooked. In this case, the device would have no rib limiting the pivoting of the handle.

  Alternatively, one could also consider a collapsible gripping device in a plane perpendicular to that of the edge of the kitchen utensil: the support would be rotated 90 relative to the example described, the axis would be horizontal for a rotation of the handle upwards. In this case, in order to keep a good solidity, the fixing screw and the components would be even longer. Such a device could, for example, be used for a collapsible handle.

  One could also consider a kitchen utensil comprising several folding grippers, for example for a pressure cooker or a fact-all.

  To facilitate the rotation of the handle and its sliding with respect to the support, it could be envisaged to add Teflon plastic sliding washers at the friction zones or to place a Teflon coating at the friction zones. important.
