Description

[0001] REMOVABLE HANDLE WITH A MOVABLE LOCK EQUIPPED WITH AN ANTI-KICKBACK DEVICE

[0002] Domain

[0003] The present invention relates to a removable handle for cooperating with a cooking vessel, the cooking vessel such as a saucepan, frying pan or Dutch oven, having a side wall which is extended upwardly by an outwardly curved portion.

[0004] State of the

[0005] Document EP3888511 discloses a removable handle intended to cooperate with a cooking container having a side wall which is extended upwards by an outwardly curved portion comprising a free end. The removable handle extends in a longitudinal direction and comprises an internal support member and an external support member intended to come against, respectively, an inner surface and an outer surface of the side wall, as well as an upper support member intended to come against the free end of the curved portion. The removable handle comprises a lock movable in translation between an open position and a closed position. The lock comprises a blocking wall intended to be moved away from the internal support member in the open position of the lock and intended to generate a force on the free end in the closed position of the lock, under the action of a pressurizing means.The latch has a projecting member and the removable handle has a fixed recessed member and in the closed position the projecting member and the recessed member are engaged with each other to prevent the latch from recoiling.

[0006] Such a device is effective in preventing the lock from recoiling and ensuring that the removable handle remains securely on the cooking vessel.

[0007] However, the protruding member may remain stuck in the recessed member when the user wants to move the lock from the closed position to the open position.

[0008] Summary of the invention

[0009] The present invention aims to remedy these drawbacks.

[0010] The technical problem underlying the invention consists of proposing a removable handle intended to cooperate with a cooking container having safe and ergonomic operation.

[0011] Another object of the present invention is to provide a removable handle which has a simple design and is economical to implement.

[0012] To this end, the subject of the invention is a removable handle intended to cooperate with a cooking container having a side wall which is extended upwards by an outwardly curved portion comprising a free end, said removable handle extending in a longitudinal direction and comprising an internal support member and an external support member intended to come against, respectively, an inner surface and an outer surface of the side wall, as well as an upper support member intended to come against the free end of the curved portion, said removable handle comprising a lock movable in translation between an open position and a closed position, the lock comprising a blocking wall intended to be moved away from the internal support member in the open position of the lock and intended to generate a force on the free end in the closed position of the lock, under the action of a pressurizing means,the lock comprising a projecting member and said removable handle comprising a fixed hollow member and in the closed position, the projecting member and the hollow member being engaged in each other to prevent the lock from moving back, characterized in that the projecting member extends transversely under the locking wall and in that the projecting member comprises a free end which cooperates with the hollow member, the free end of the projecting member being movable between a locking position in which the lock cannot move back and an unlocking position in which the lock can move back. It is understood that the lock is guided in the removable handle with an operating clearance sized to allow, when the lock reaches the closed position,a downward movement of the locking wall under the action of the pressure means and in reaction to the pressure on the free end of the curved portion. The projecting member which is arranged as close as possible to the locking wall, performs the same movement to move from the unlocking position to the locking position and to be housed in the hollow member. The projecting member performs an inverse movement to move from the locking position to the unlocking position when the lock leaves the closed position to move into the open position.,

[0013] By the projecting member extending transversely under the blocking wall, it is understood that the projecting member extends under the blocking wall downwards.

[0014] Advantageously, the lock is movable in a direction parallel to the longitudinal direction.

[0015] Advantageously, the hollow organ has a height H of less than 0.5 millimeters.

[0016] Thus, the projecting member makes a very short movement to move from the locking position to the unlocking position when the lock moves from the closed position to the open position. As a result, the projecting member cannot remain blocked in the recessed member when the user moves the lock from the closed position to the open position.

[0017] Advantageously, the hollow organ has a height H of less than 0.3 millimeters.

[0018] Preferably, the projecting member extends under the locking wall of the lock in a direction of extension, the direction of extension and the locking wall forming an angle θ of between 60° and 120° in a vertical plane passing through the longitudinal direction. In the closed position, the free end of the curved portion exerts on the locking wall in reaction to the action of the pressure-applying means a force oriented downwards in a direction close to the direction of extension of the projecting member.

[0019] Advantageously, the direction of extension of the projecting member and the locking wall of the lock forms an angle 0 equal to 90° in a vertical plane passing through the longitudinal direction.

[0020] Advantageously, the projecting member takes the form of a tab which extends along the direction of extension and which has a rectangular cross-section to the direction of extension. The rectangular cross-section is preferably constant.

[0021] Preferably, the hollow member comprises at least one housing for receiving the free end of the projecting member.

[0022] Advantageously, in a vertical plane passing through the longitudinal direction, the at least one housing has a V shape provided with a first flat face inclined at an angle [3 relative to the longitudinal direction, the angle [3 being less than 25° and the free end of the projecting member has a lower edge which cooperates with the first flat face in the locking position.

[0023] Advantageously, the lower edge can be slightly radiused with a radius of less than one millimeter.

[0024] Thus, with a very small angle [3, the projecting member can easily disengage from the hollow member by a very short movement when the lock leaves the closed position to move into the open position.

[0025] Preferably, the first planar face and the lower edge extend perpendicular to the vertical plane passing through the longitudinal direction.

[0026] Advantageously, the first flat face extends perpendicular to the vertical plane passing through the longitudinal direction over a width LF and in that the lower edge extends perpendicular to the vertical plane passing through the longitudinal direction over a width LA, LF and / or LA being greater than 5 millimeters.

[0027] Such an arrangement allows for a robust construction.

[0028] Preferably, the hollow member comprises a plurality of receiving housings arranged along the longitudinal direction and which have a pitch P between two successive housings, the pitch P being less than 1.5 millimeters.

[0029] Thus, depending on the position of the lock linked to the thickness and length of the free end of the curved portion of the vertical wall when moving to the closed position, the projecting member will be housed in one of the receiving housings to move to the locking position.

[0030] Advantageously, the lock is movable in translation in the longitudinal direction and the blocking wall is inclined to form with the longitudinal direction in a vertical section plane including the longitudinal direction, an angle α greater than 40°.

[0031] Thus, the free end generates on the blocking wall and vice versa a force comprising a vertical blocking component substantially perpendicular to the longitudinal direction.

[0032] Advantageously, the locking wall is intended to cooperate with a lower edge of the free end of the curved portion of the vertical wall in the closed position of the lock.

[0033] Preferably, the pressure-applying means comprise a compression spring and the thrust of the spring on the lock is carried out in the longitudinal direction when the lock is in the closed position.

[0034] This arrangement allows the position of the lock to be adapted to the thickness and length of the free end of the curved portion of the vertical wall.

[0035] Advantageously, the removable handle comprises means for operating the toggle lock, the operating means comprising a lever, a connecting rod and the compression spring.

[0036] This arrangement allows for very ergonomic means of operating the lock.

[0037] Advantageously, the lock is movable relative to the internal support, external support and upper support members, which are all three integral and fixed.

[0038] The invention also relates to an assembly formed by at least one cooking container comprising a side wall which is extended upwards by a portion curved outwards comprising a free end provided with an upper edge and a lower edge and a removable handle as previously described.

[0044] - figure 5 illustrates a detail view D of the free end of the projecting member in the locking position in the hollow member and of the removable handle illustrated in figure 1.

[0045] - Only the elements necessary for understanding the invention have been shown. To facilitate reading of the drawings, the same elements bear the same references from one figure to another.

[0046] It should be noted that in this document, the terms "horizontal", "vertical", "lower", "upper", "top", "bottom", "front", "rear", "longitudinal", "transverse", used to describe the removable handle and the cooking container refer to this removable handle in use, when it is mounted on a side wall of the cooking container, which is placed on a horizontal plane.

[0047] As seen in Figures 1 to 3, a removable handle 1 is intended to cooperate with a cooking container 60 which comprises a horizontal bottom wall 68, a side wall 61 rising from the bottom wall 68, and a curved portion 64 which extends outwardly. The side wall 61 has an inner surface 62 and an outer surface 63. The curved portion 64 extends the side wall 61 and delimits the upper opening of the cooking container 60. The curved portion 64 comprises a free end 65 provided with an upper edge 66 and a lower edge 67. The upper 66 and lower 67 edges are preferably superimposed in a vertical plane.

[0048] The removable handle 1 extends in a longitudinal direction 3. The removable handle 1 comprises a gripping body 2 which comprises at a front end directed towards the cooking container 60 a front wall 4 forming an external support member 14 intended to cooperate with the external surface 63 of the side wall 61. In a vertical section plane passing through the longitudinal direction 3 (Figs. 2 and 3), the external support member 14 is substantially vertical. The removable handle 1 comprises a vertical median plane which comprises the longitudinal direction 3 and which forms a plane of symmetry for the removable handle 1.

[0049] The removable handle 1 comprises a structural part 10 which is made of metallic material. The structural part 10 is substantially planar and comprises an end tab 13. The end tab 13 extends downwards and comprises an internal wall forming an internal support member 12 intended to cooperate with the internal surface 62 of the side wall 61. The structural part 10 comprises two portions 51 arranged on either side of the vertical median plane. The two portions 51 form an upper support member 15 intended to cooperate with the upper edge 66 of the free end 65. The two portions 51 extend along the longitudinal direction 3, at the level of the front end of the gripping body 2.

[0050] The internal support member 12 and the external support member 14 are offset in the longitudinal direction 3 (Fig. 3) to allow the introduction of the side wall 61 and the free end 65 when assembling the removable handle 1 on the cooking container 60.

[0051] The removable handle 1 comprises a locking member formed by a latch 20 movable in translation in the longitudinal direction 3 between an open position (Fig. 3) and a closed position (Fig. 2). The latch 20 comprises a substantially planar central portion 22 which extends in the longitudinal direction 3. The latch 20 is slidably mounted under the structural part 10 by folding two lateral tabs of the structural part 10. The structural part 10 comprises a pin 16 of square section which extends downwards. The central portion 22 of the latch 20 comprises a housing 23 which extends along the longitudinal axis 3. The housing 23 receives the pin 16 to guide the latch 20 in translation. The latch 20 comprises at a front end a blocking wall 21.As seen in Figure 3, in the open position of the lock 20, the blocking wall 21 is intended to be moved away from the upper support member 15 to allow the introduction of the side wall 61 between the internal 12 and external 14 support members and allow the upper edge 66 of the free end 65 to come against the upper support member 15.

[0052] As seen in Figure 2, in the closed position of the lock 20, the blocking wall 21 is intended to bear against the lower edge 67 of the free end 65 and thus block the upper edge 66 against the upper support member 15. In a vertical section plane passing through the longitudinal direction 3, a straight line belonging to the blocking wall 21 and the longitudinal direction form an angle a of between 40 and 50°, preferably 45°.

[0053] According to Figures 2 to 5, the lock 20 comprises a projecting member 24 which extends transversely downwards under the blocking wall 21. The projecting member 24 extends under the blocking wall 21 in a direction of extension 5 (Fig. 4) which is perpendicular to the blocking wall 21. Thus the direction of extension 5 of the projecting member 24 forms with the blocking wall 21 an angle 9 equal to 90° in a vertical plane passing through the longitudinal direction 3. The projecting member 24 takes the form of a tab which extends along the direction of extension 5 and which has a rectangular cross-section to the direction of extension 5. The projecting member 24 comprises a free end 25 which has a rectangular flat face 26 substantially parallel to the blocking wall 21. The free end 25 has a front face 27 which forms with the rectangular flat face 26 a lower edge 29.The lower edge 29 extends perpendicular to the vertical plane passing through the longitudinal direction 3. The lower edge 29 extends perpendicular to the vertical plane passing through the longitudinal direction 3 over a width LA equal to 10 millimeters. The projecting member 24 is integral with the lock 20 and moves with it between the open position and the closed position and vice versa.

[0054] The removable handle 1 comprises a reinforcing piece 50 which is fixed to the gripping body 2 and which is also fixed to a free end 18 of the pin 16 by a screw 19. Thus, the reinforcing piece 50 is rigidly connected to the structural part 10. The reinforcing piece 50 is made from a metal strip and has a rectangular cross-section. The reinforcing piece 50 comprises a notched portion 52 (Figs. 4 and 5) which extends along the longitudinal axis 3, under the projecting member 24. The notched portion 52 comprises a succession of hollow members 54, all identical. The succession of hollow members 54 has a pitch P (Fig. 5) between two successive hollow members 54 equal to 1 millimeter. Each hollow member 54 has a height H equal to 0.25 millimeter. The hollow member 54 comprises a receiving housing 56 for the free end 25 of the projecting member 24.In a vertical plane passing through the longitudinal direction 3, the receiving housing 56 has a V-shape provided with a first flat face 57 inclined at an angle [31 relative to the longitudinal direction 3. The angle [31 is equal to 20°. The V-shape is provided with a second flat face 58 inclined at an angle [32 equal to 60° relative to the longitudinal direction 3. The first 57 and second 58 flat faces and the lower edge 29 extend perpendicular to the vertical plane passing through the longitudinal direction 3. The first flat face 57 extends perpendicular to the vertical plane passing through the longitudinal direction 3 over a width LF equal to 10 millimeters.

[0055] The lower edge 29 of the free end 25 of the projecting member 24 cooperates with a first flat face 57 of a receiving housing 56 of a hollow member 54 when the lock 20 passes into the closed position. The free end 25 of the projecting member 24 is movable between a locking position (Fig. 5) in which the lower edge 29 bears on the first flat face 57 to prevent the lock 20 from moving back and an unlocking position in which the lower edge 29 is moved away from the first flat face 57 to allow the lock 20 to move back.

[0056] In the closed position of the lock 20, the projecting member 24 and the hollow member 54 are engaged in each other in the locking position to prevent the lock 20 from moving back when the free end 65 generates on the locking wall 21 a force comprising a vertical component F1, oriented downwards and the intensity of which is greater than a predetermined value equal to 2.5 N. The central portion 22 of the lock 20 is guided in translation with a vertical clearance sized to allow the projecting member 24 to move from the unlocking position to the locking position in the hollow member 54 or vice versa.

[0057] As seen in Figures 2 to 4, the removable handle 1 comprises a means for returning the lock 20 arranged between a tab 39 carried by the structural part 10 and a stop 28 carried by the lock 20. The return means is formed by a spring 11 which works in compression when the lock 20 is in the closed position and which is adapted to apply a return force to the stop 28 to drive the lock 20 towards its open position.

[0058] According to Figures 2 and 3, the removable handle 1 comprises means for moving the locking member formed by the lock 20. The moving means comprise a lever 30 which is pivotally mounted on the gripping body 2 along a pivot axis 34 extending in a transverse direction, perpendicular to the longitudinal direction 3, and a connecting rod 40 which allows the movement of the lock 20 when the lever 30 is pivoted. The connecting rod 40 is pivotally mounted, by a first end to the lock 20 along an axis 43, and by a second end to the lever 30 along an axis 44 which is slidably mounted in an oblong opening made in the lever 30.

[0059] The lever 30 is arranged on a lower face 6 of the gripping body 2 and is movable between a closed position (Fig. 2) and an open position (Fig. 3) via an intermediate position of unstable equilibrium. In the closed position of the lever 30, the latch 20 is in the closed position and in the open position of the lever 30, the latch 20 is in the open position. In addition, the displacement means also comprise a spring 47 which is arranged between the slidably mounted axis 44 and a transverse wall 32 of the lever 30. This compression spring 47 allows adjustment of the position of the latch 20 in the closed position to the thickness of the side wall 61 of the cooking container 60.

[0060] According to Figure 2, in the closed position of the lever 30, the axis 44 around which the second end 42 pivots is located above a line passing through the pivot axis 34 and the axis 43. The second end 42 is kept in contact with the structural part 10 under the action of the compression spring 47. Thus, the lock 20 remains naturally in its closed position, without the user having to maintain any force on the removable handle 1. The intermediate unstable equilibrium position of the lever 30 is reached when the axis 44 around which the second end 42 pivots is moved below the line passing through the pivot axis 34 and the axis 43.

[0061] As seen in Figures 1 to 3, the removable handle 1 comprises an opening button 17 which allows the lever 30 to be moved initially into its closed position beyond its intermediate unstable equilibrium position. The opening button 17 is arranged on an upper face of the gripping body 2. The opening button 17 is rotatable about a transverse axis, horizontal to the longitudinal direction 3 of the removable handle 1. The opening button 17 is movable between a lowered rest position in which the lever 30 is in its closed position, an intermediate raised position in which the lever is in its intermediate unstable equilibrium position and a raised position in which the lever 30 is in its open position.

[0062] In operation, to disassemble the removable handle 1 from the cooking container 60, the user grasps the gripping body 2 and pivots the opening button 17 with the thumb from the lowered rest position in which the lever 30 is in its closed position to the raised position in which the lever 30 is in its open position. The passage of the lever 30 from its closed position to its open position causes a reduction in the force exerted by the compression spring 47 on the locking wall 21 against the free end 65 of the curved portion 64. The lower edge 29 can then separate from the first flat face 57 to exit the receiving housing 56 and the lock 20 can pass from its closed position to its open position.

[0063] To assemble the removable handle 1 onto the cooking container 60, the user grasps the gripping body 2 and, following the same operating procedure as that described above, brings the lock 20 into its open position. He introduces the free end 65 of the curved portion 64 between the internal support member 12 and the external support member 14 to bring the inner surface 62 of the side wall 61 against the internal support member 12 and the outer surface 63 against the external support member 14, and also to bring the upper edge 66 against the two portions 51. Then, he presses the lever 30 to move it from its open position to its closed position and thus drive the lock 20 from its open position to its closed position. The blocking wall 21 under the action of the compression spring 47 then bears against the lower edge 67 of the free end 65 and thus blocks the upper edge 66 against the two portions 51.The free end 65 of the curved portion 64 then generates on the blocking wall 21 a force which comprises a component F1 opposite to the vertical blocking component F, oriented downwards, which moves the blocking wall 21 downwards. Thus, the lower edge 29 of the free end 25 of the projecting member 24 is engaged in a receiving housing 56 of the hollow member 54 to come to bear on the first flat face 57 and the lock 20 passes into the closed position. When the user wants to turn the food contained in the cooking container 60, for example to turn pancakes, and he prints with the removable handle 1 on the cooking container 60 a movement from bottom to top while vigorously braking the movement at the end of travel, the free end 65 of the curved portion 64 exerts a significant force on the blocking wall 21.But the lower edge 29 which rests on the first flat face 57, in the receiving housing 56, prevents the lock 20 from moving back.

[0064] Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only as an example. Modifications remain possible, in particular 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.

[0065] Thus, in an alternative embodiment not illustrated, the blocking wall 21 has a front end and the projecting member 24 extends transversely under the front end. Possibility of industrial application

[0066] The invention finds its industrial application in the design, manufacture or use of removable handles for cooking containers.
