Description

Technical Field

[0001] The present invention relates to a detachable handle for use with a cooking vessel, such as a soup pot, a frying pan or a stew pot, the side wall of which is extended upwardly by an outwardly curved portion. Background Art

[0002] From document EP3888511 a detachable handle is known for cooperating with a cooking vessel having a side wall extending upwardly through an outwardly curved portion having a free end. The detachable handle extends in a longitudinal direction and comprises an inner support and an outer support for engaging with the inner and outer surfaces of the side wall, respectively, and an upper support for engaging with the free end of the curved portion. The detachable handle comprises a lock that can be moved in translation between an open position and a closed position. The lock comprises a blocking wall for moving away from the inner support when the lock is in the open position and for exerting a force on the free end under the action of a pressure-applying device when the lock is in the closed position. The lock comprises a protrusion, and the detachable handle comprises a fixed retracted member, and in the closed position, the protrusion and the retracted member are interlocked to prevent the lock from rebounding.

[0003] This device can effectively prevent the lock from bouncing back and ensure that the detachable handle is fixed on the cooking vessel.

[0004] However, when the user attempts to move the lock from the closed position to the open position, the protruding member will still be caught in the retracted member. Summary of the invention

[0005] The present invention aims to remedy these drawbacks.

[0006] The technical problem of the present invention is to provide a detachable handle, which is used to cooperate with a cooking vessel and is safe to operate and ergonomic.

[0007] Another object of the present invention is to provide a detachable handle that is simple in design and economical in operation.

[0008] To this end, the object of the present invention is a detachable handle for cooperating with a cooking vessel having a side wall, the side wall extending upwardly through an outwardly curved portion having a free end, the detachable handle extending in a longitudinal direction and comprising an inner support and an outer support, the inner support and the outer support being respectively used to engage with the inner surface and the outer surface of the side wall, and an upper support being used to engage with the free end of the curved portion, the detachable handle comprising a lock that can be translated between an open position and a closed position, the lock comprising a blocking wall, in the open position of the lock, the blocking wall is away from the inner support, under the action of a pressure applying device, the blocking wall exerts a force on the free end of the closed position of the lock, the lock comprising a protrusion, the detachable handle comprising a fixed retracted member, in the closed position, the protrusion and the retracted member interlock to prevent the lock from rebounding, characterized in that the protrusion extends laterally below the blocking wall and has a free end that cooperates with the retracted member, and the free end of the protrusion can be moved between a blocking position where the lock cannot rebound and an unblocking position where the lock can rebound.

[0009] It is understood that the guide of the lock in the removable handle has an operating clearance, the size of which is designed so that when the lock is in the closed position, under the action of the pressure applying device and under the reaction force of the pressure applied to the free end of the curved portion, the blocking wall can move downward. The protrusion arranged as close as possible to the blocking wall performs the same movement, from the unblocking position to the blocking position, and is accommodated in the retracted part. When the lock moves from the closed position to the open position, the protrusion moves towards each other, from the blocking position to the unblocking position.

[0010] “The protrusion extends laterally to below the barrier wall” means that the protrusion extends downward to below the barrier wall.

[0011] Advantageously, the lock is movable in a direction parallel to the longitudinal direction.

[0012] Advantageously, the height H of the recessed element is less than 0.5 mm.

[0013] Therefore, when the lock moves from the closed position to the open position, the protruding member only needs to move very shortly to move from the blocking position to the unblocking position. Therefore, when the user moves the lock from the closed position to the open position, the protruding member will not be blocked in the retracted member.

[0014] Advantageously, the height H of the recessed element is less than 0.3 mm.

[0015] Preferably, the protruding piece extends to below the blocking wall of the lock along an extending direction, and the extending direction and the blocking wall form an angle θ of 60° to 120° on a vertical plane passing through the longitudinal direction.

[0016] In the closed position, the free end of the bent portion applies a force downward to the barrier wall along a side close to the extending direction of the protruding piece under the action of the pressure applying device.

[0017] Advantageously, the extension direction of the protruding piece forms an angle θ equal to 90° with the blocking wall of the lock on a vertical plane passing through the longitudinal direction.

[0018] Advantageously, the protrusion is in the form of a tab extending in the direction of extension and having a rectangular cross section transverse to the direction of extension. The rectangular cross section is preferably constant.

[0019] The retracted member preferably comprises at least one receiving housing for receiving the free end of the protruding member.

[0020] Advantageously, in a vertical plane passing through the longitudinal direction, at least one shell is V-shaped, the shell is provided with a first plane inclined at an angle β relative to the longitudinal direction, the angle β is less than 25°, and the free end of the protrusion has a lower edge which cooperates with the first plane in the blocking position.

[0021] Advantageously, the lower edge can be slightly divergent with a radius of less than one millimeter.

[0022] Therefore, as long as the angle β is very small, the protruding member can easily disengage from the retracted member with only a very short movement when the lock moves from the closed position to the open position.

[0023] Preferably, the first plane and the lower edge extend perpendicularly to a vertical plane passing through the longitudinal direction.

[0024] Advantageously, the first plane extends perpendicularly to a vertical plane passing through the longitudinal direction and has a width LF, the lower edge extends perpendicularly to a vertical plane passing through the longitudinal direction and has a width LA, and LF and / or LA exceed 5 mm.

[0025] Such an arrangement results in a sturdy structure.

[0026] Preferably, the retracted member comprises a plurality of receiving housings arranged in the longitudinal direction, with a spacing P between two consecutive housings, and the spacing P is less than 1.5 mm.

[0027] Thus, when switching to the closed position, the projection will be seated in one of the receiving housings as a function of the locking position associated with the thickness and the length of the free end of the curved portion of the vertical wall, so as to switch to the blocking position.

[0028] Advantageously, the lock is translatable in the longitudinal direction, the blocking wall being inclined, forming an angle α with the longitudinal direction greater than 40° in a vertical cross section including the longitudinal direction.

[0029] The free end thus generates an action and reaction force on the barrier wall, which force comprises a vertical barrier component substantially perpendicular to the longitudinal direction.

[0030] Advantageously, the blocking wall is designed to cooperate with the lower edge of the free end of the curved portion of the vertical wall in the closed position of the lock.

[0031] Preferably, the pressure applying means comprises a compression spring, and when the lock is in the closed position, the urging force applied by the spring to the lock is in the longitudinal direction.

[0032] This arrangement allows the locking position to be adapted to the thickness and length of the free end of the curved portion of the vertical wall.

[0033] Advantageously, the detachable handle comprises a toggle-type operating device for operating the lock, the operating device comprising a lever, a connecting rod and a compression spring.

[0034] This design makes the lock very ergonomic to operate.

[0035] Advantageously, the lock is movable relative to the inner, outer and upper supports, whereas all three components are integrally connected and fixed.

[0036] The invention also relates to an assembly consisting of at least one cooking vessel having a side wall extending upwards by a portion bent outwards and comprising a free end provided with an upper edge and a lower edge, and a detachable handle as described above.

[0043] Only the elements necessary for understanding the present invention are shown in the figures. For ease of reading, the same elements in the various figures are marked with the same reference numerals.

[0044] It should be noted that, in this document, the terms "horizontal", "vertical", "lower", "upper", "top", "bottom", "front", "rear", "longitudinal" and "lateral" used to describe the detachable handle and the cooking vessel are with reference to when the detachable handle in use is installed on the side wall of the cooking vessel placed on a horizontal surface.

[0045] like Figures 1 to 3 As shown, the detachable handle 1 is used in conjunction with a cooking vessel 60 having a horizontal bottom wall 68, a side wall 61 rising from the bottom wall 68, and an arcuate portion 64 extending outward. The side wall 61 has an inner surface 62 and an outer surface 63. The arcuate portion 64 extends the side wall 61 and defines an upper opening of the cooking vessel 60. The arcuate portion 64 includes a free end 65, which is provided with an upper edge 66 and a lower edge 67. The upper edge 66 and the lower edge 67 preferably overlap in a vertical plane.

[0046] The detachable handle 1 extends in the longitudinal direction 3. The detachable handle 1 comprises a clamping body 2 which comprises, at its front end facing the cooking vessel 60, a front wall 4 forming an outer support 14 for cooperating with the outer surface 63 of the side wall 61. In a vertical cross section through the longitudinal direction 3 ( Figure 2 and Figure 3 ), the outer support 14 is substantially vertical. The detachable handle 1 comprises a vertical middle plane, which comprises the longitudinal direction 3 and forms a plane of symmetry of the detachable handle 1 .

[0047] The removable handle 1 comprises a structural member 10 made of a metal material. The structural member 10 is substantially flat and comprises an end piece 13. The end piece 13 extends downward and has an inner wall, which forms an inner support 12 for cooperating with the inner surface 62 of the side wall 61. The structural member 10 comprises two parts 51, which are located on both sides of the vertical middle plane. The two parts 51 form an upper support 15, which cooperates with the upper edge 66 of the free end 65. The two parts 51 extend in the longitudinal direction 3 and are located at the front end of the clamping body 2.

[0048] The inner support member 12 and the outer support member 14 are offset in the longitudinal direction 3 ( Figure 3 ) so as to introduce the side wall 61 and the free end 65 when the detachable handle 1 is assembled on the cooking vessel 60.

[0049] The detachable handle 1 comprises a locking element formed by a lock 20 which can be moved in an open position ( Figure 3 ) and closed position ( Figure 2 ) between the longitudinal axis 3. The lock 20 comprises a substantially flat central portion 22 extending in the longitudinal direction 3. The lock 20 is slidably mounted below the structural component 10 by means of two side pieces of the curved structural component 10. The structural component 10 comprises a pin 16 of square cross section extending downwardly. The central portion 22 of the lock 20 comprises a housing 23 extending along the longitudinal axis 3. The housing 23 accommodates the pin 16 to guide the lock 20 in translation. The lock 20 comprises a blocking wall 21 at the front end.

[0050] like Figure 3 As shown, in the open position of the lock 20 , the blocking wall 21 is designed to be away from the upper support 15 so as to introduce the side wall 61 between the inner support 12 and the outer support 14 and to bring the upper edge 66 of the free end 65 into engagement with the upper support 15 .

[0051] from Figure 2 As can be seen in the figure, in the closed position of the lock 20, the blocking wall 21 is designed to abut against the lower edge 67 of the free end 65, thereby blocking the upper edge 66 from abutting against the upper support 15. In a vertical cross section through the longitudinal direction 3, the straight line belonging to the blocking wall 21 forms an angle α with the longitudinal direction of between 40 and 50°, preferably 45°.

[0052] according to Figures 2 to 5 The lock 20 includes a protrusion 24, which extends laterally downward to below the blocking wall 21. The protrusion 24 extends in a direction 5 ( Figure 4 ) extends below the barrier wall 21. Therefore, the extension direction 5 of the projection 24 forms an angle θ equal to 90° with the barrier wall 21 on a vertical plane passing through the longitudinal direction 3. The projection 24 is in the form of a lug, which extends along the extension direction 5 and has a rectangular cross section transverse to the extension direction 5. The projection 24 includes a free end 25, which has a rectangular plane 26 substantially parallel to the barrier wall 21. The free end 25 includes a front end face 27, which forms a lower edge 29 with the rectangular plane 26. The lower edge 29 extends perpendicularly to the vertical plane passing through the longitudinal direction 3. The lower edge 29 extends perpendicularly to the vertical plane passing through the longitudinal direction 3 over a width LA equal to 10 mm. The projection 24 is integral with the lock 20 and moves therewith between an open position and a closed position or vice versa.

[0053] The detachable handle 1 comprises a reinforcement member 50 which is connected to the clamping body 2 and to the free end 18 of the pin 16 by means of a screw 19. Thus, the reinforcement member 50 is rigidly connected to the structural member 10. The reinforcement member 50 is made of a metal strip and has a rectangular cross section. The reinforcement member 50 comprises a notched portion 52 ( Figure 4 and Figure 5 ), which extends along the longitudinal axis 3 and is located below the protruding member 24. The recessed portion 52 includes all identical continuous indentations 54. The continuous indentations 54 have a spacing P ( Figure 5 ) is equal to 1 mm. The height H of each indentation 54 is equal to 0.25 mm. The indentation 54 includes a housing 56 for receiving the free end 25 of the protrusion 24. On a vertical plane passing through the longitudinal direction 3, the receiving housing 56 is V-shaped, and its first plane 57 is inclined at an angle β1 relative to the longitudinal direction 3. The angle β1 is equal to 20°. The V-shape is provided with a second plane 58, which is inclined at an angle β2 equal to 60° relative to the longitudinal direction 3. The first plane 57 and the second plane 58 and the lower edge 29 extend perpendicularly to the vertical plane passing through the longitudinal direction 3. The first plane 57 extends perpendicularly to the vertical plane passing through the longitudinal direction 3 by a width LF equal to 10 mm.

[0054] When the lock 20 is switched to the closed position, the lower edge 29 of the free end 25 of the protruding member 24 cooperates with the first flat surface 57 of the housing 56 to receive the retracted member 54. The free end 25 of the protruding member 24 can be in the blocking position ( Figure 5 ) and an unblocking position, in which the lower edge 29 is located on the first plane 57 to prevent the lock 20 from rebounding; in the unblocking position, the lower edge 29 is away from the first plane 57 to allow the lock 20 to rebound.

[0055] In the closed position of the lock 20 , the protruding piece 24 and the retracted piece 54 are mutually locked in the blocking position to prevent the lock 20 from rebounding when the free end 65 exerts on the blocking wall 21 a downward force including a vertical component F1 whose intensity is greater than a predetermined value, which is equal to 2.5 N. The central part 22 of the lock 20 is guided in translation, and its vertical play is of a size that allows the movement of the protruding piece 24 in the retracted piece 54 from the unblocking position to the blocking position or vice versa.

[0056] like Figures 2 to 4 As shown, the detachable handle 1 comprises return means for returning the lock 20, which are arranged between a tab 39 carried by the structure 10 and a stop 28 carried by the lock 20. The return means are formed by a spring 11, which works in a compressed state when the lock 20 is in the closed position and is suitable for applying a return force to the stop 28 to move the lock 20 towards its open position.

[0057] according to Figure 2 and Figure 3, the detachable handle 1 comprises a plurality of movement means for moving the locking element, which are formed by the lock 20. The movement means comprise a lever 30 mounted on the clamping body 2 so as to be rotatable about a rotation axis 34 extending in a transverse direction, perpendicular to the longitudinal direction 3, and a connecting rod 40, the lever 30 being mounted so as to be rotatable about a rotation axis 34 extending in a transverse direction, perpendicular to the longitudinal direction 3, the connecting rod 40 allowing the lock 20 to be moved when the lever 30 is rotated. The connecting rod 40 is mounted on the lock 20 at a first end so as to be rotatable about an axis 43, and is mounted on the lever 30 at a second end so as to be rotatable about an axis 44, the axis 44 being mounted so as to be slidable in an oblong opening of the lever 30.

[0058] The lever 30 is mounted on the lower end face 6 of the clamping body 2 and can be in the closed position ( Figure 2 ) and open position ( Figure 3 ) and passes through an intermediate position of unstable equilibrium. In the closed position of the lever 30, the lock 20 is in the closed position, and in the open position of the lever 30, the lock 20 is in the open position. In addition, the displacement device also includes a spring 47, which is arranged between the shaft 44 mounted to slide and the transverse wall 32 of the lever 30. The compression spring 47 allows the position of the lock 20 in the closed position to be adjusted according to the thickness of the side wall 61 of the cooking vessel 60.

[0059] according to Figure 2 In the closed position of the lever 30, the shaft 44 is located above the line passing through the rotation axis 34 and the shaft 43, and the second end 42 rotates around the shaft 44. Under the action of the compression spring 47, the second end 42 is kept in contact with the structural member 10. Therefore, the lock 20 is naturally kept in the closed position without the user applying any force to the detachable handle 1. When the shaft 44 moves below the line passing through the rotation axis 34 and the shaft 43, the lever 30 reaches an intermediate position of unstable equilibrium, and the second end 42 rotates around the shaft 44.

[0060] like Figures 1 to 3 As shown, the detachable handle 1 comprises an opening button 17, which allows the lever 30, initially in its closed position, to be moved out of an intermediate position of unstable equilibrium. The opening button 17 is arranged on the upper surface of the clamping body 2. The opening button 17 can be rotated about a transverse axis, which is horizontal to the longitudinal direction 3 of the detachable handle 1. The opening position 17 can be moved between a lowered rest position in which the lever 30 is in the closed position, an intermediate raised position in which the lever is in unstable equilibrium, and a raised position in which the lever 30 is in the open position.

[0061] In operation, to remove the detachable handle 1 from the cooking vessel 60, the user grasps the clamping body 2 and rotates the opening button 17 with his / her thumb from the lowered rest position in which the lever 30 is in the closed position to the raised position in which the lever 30 is in the open position. Switching the lever 30 from its closed position to the open position causes a reduction in the force exerted by the compression spring 47 on the barrier wall 21 against the free end 65 of the curved portion 64. In this way, the lower edge 29 can be separated from the first plane 57 and away from the receiving housing 56, and the lock 20 can be switched from the closed position to the open position.

[0062] When mounting the removable handle 1 on the cooking vessel 60, the user holds the clamping body 2 and moves the lock 20 to its open position according to the same operating mode as described above. He / she inserts the free end 65 of the arcuate portion 64 between the inner support 12 and the outer support 14, so that the inner surface 62 of the side wall 61 abuts against the inner support 12, the outer surface 63 abuts against the outer support 14, and the upper edge 66 abuts against the two parts 51. He / she then presses the lever 30 to switch it from its open position to its closed position, thereby moving the lock 20 from its open position to its closed position. Under the action of the compression spring 47, the blocking wall 21 abuts against the lower edge 67 of the free end 65, thereby blocking the upper edge 66 between the two parts 51. The free end 65 of the arcuate portion 64 then generates a force on the blocking wall 21 with a downward component F1 opposite to the vertical blocking component F, causing the blocking wall 21 to move downward. Therefore, the lower edge 29 of the free end 25 of the protruding member 24 engages with the receiving housing 56 of the retracted member 54 to abut against the first plane 57, and the lock 20 enters the closed position. When the user wants to turn over the food contained in the cooking vessel 60, such as flipping a pancake, and uses the detachable handle 1 on the cooking vessel 60 to move from bottom to top, and brakes with energy at the end of the movement, the free end 65 of the curved portion 64 applies a large force to the blocking wall 21. However, the lower edge 29 abutting against the first plane 57 prevents the lock 20 from rebounding in the receiving housing 56.

[0063] Of course, the present invention is by no means limited to the described and illustrated embodiments, which are merely illustrative. Without departing from the scope of the present invention, modifications are still possible, in particular from the perspective of the composition of the various elements or the substitution of technical equivalents.

[0064] Therefore, in another embodiment not shown, the barrier wall 21 has a front end, and the protrusion 24 extends laterally below the front end.
