Abstract
Description
Technical Field
[0001] This invention relates to the general technical field of food pressure cooking appliances, particularly household appliances of the pressure cooker type, which are designed to form a cooking chamber capable of increasing pressure to ensure steam pressure cooking of the food contained therein. Background Technology
[0002] More specifically, the present invention relates to a food pressure cooking appliance, comprising:
[0003] A bowl; a lid for locking relative to the bowl so as to form a cooking chamber suitable for pressure rise together with the bowl;
[0004] A bayonet-type locking system is configured to ensure the lid is locked and unlocked relative to the bowl by rotating the lid relative to the bowl;
[0005] A support attached to the lid, allowing the lid to rotate relative to the support about a first axis of rotation between two positions corresponding to an unlocked mode and a locked mode, respectively; and
[0006] - A manually operable locking / unlocking control component, for attachment to the support via a mechanical connection, to allow manual movement of the control component relative to the support.
[0007] A conversion device for converting the manual movement of the control component into rotation of the lid relative to the support, the conversion device comprising at least one drive structure carried by the manual control component, and at least one driven structure connected to the lid and engaging the drive structure.
[0008] - and a pressure regulating device for maintaining the pressure inside the cooking chamber at a set point level.
[0009] Pressure cookers, especially those for home use, are well-known. They typically consist of a metal bowl with a similarly metal lid airtightly attached to it via a flexible, ring-shaped sealing gasket, creating a cooking chamber capable of increasing pressure. The lid is attached to the bowl via a locking mechanism, allowing the pressure cooker lid to switch between a locked mode (when the cooking chamber can increase pressure) and an unlocked mode (when the lid can be freely detached from the bowl).
[0010] Different types of locking devices exist in the prior art. One of the most widely used systems is the bayonet locking system, which is based on movable ramps on the bowl and lid, designed to allow the lid to slide into contact with each other after rotation, thereby ensuring a continuous mechanical connection to prevent separation of the bowl and lid under increased pressure. The movable ramp on the lid is typically formed by partially folding the annular descending edge of the lid inward, while the movable ramp on the bowl is obtained by folding and cutting the free upper edge of the bowl.
[0011] This bayonet-type locking system is completely satisfactory, especially due to its relatively light weight, simple manufacturing process, and reliability.
[0012] However, in its most basic embodiment, the aforementioned bayonet locking system has some significant drawbacks, particularly in terms of practicality and ergonomics.
[0013] To overcome these shortcomings, a bayonet-type pressure cooker with a force reduction control mechanism has been proposed, which is based on a rotary control arch that drives the sliding motion of the carriage. The arch itself responds through a lever system that allows the lid to be rotated.
[0014] This system is perfectly satisfactory in terms of ease of use and ergonomics. However, it also has some drawbacks.
[0015] In particular, the maintenance and cleaning of such pressure cookers can be complex and time-consuming, especially considering the numerous components mounted on the lid, particularly the movable parts. Therefore, cleaning such pressure cookers in a dishwasher is complicated, or even impossible. While the many components mounted on the lid do directly or indirectly ensure safety functions, they must therefore avoid repeated thermal or mechanical stresses that could cause premature aging or even damage. This prevents thoroughly cleaning such pressure cookers in a dishwasher to protect these components and mechanisms. Furthermore, among other considerations, the lid itself of such pressure cookers largely limits, or even prohibits, cleaning in a dishwasher.
[0016] The size of the lid of this known pressure cooker also complicates its procurement and storage.
[0017] Furthermore, if one of the many moving parts (rotating arch, carriage, rod, etc.) that make up the pressure relief system in such a known pressure cooker breaks or is damaged, its repair can be very tricky and time-consuming, even for professionals.
[0018] Finally, most of the distinctive features of the aforementioned commercially available pressure cookers are typically located on components mounted on the lid. In fact, these components are easier and less costly to work with in terms of shape, color, or surface finish than the lid itself, making the pressure cooker easily visually identifiable. For reasons of industrial standardization, it is therefore important to create a unique model of lid and bowl for a given size pressure cooker, as the components of the control mechanism mounted on the lid contribute to the differences between products.
[0019] Therefore, this industrial operation that differentiates products should be carried out as late as possible in order to benefit from maximum inventory flexibility and to adjust the production of such models to the greatest extent possible according to market demand. Summary of the Invention
[0020] However, the complexity of the control mechanisms of the aforementioned known pressure cookers, and the complexity resulting from the numerous moving parts (rotating arches, carriages, rods, etc.), necessitates the relatively early installation of different components of the lid-supporting mechanism on the production line so that the known design can prevent product differentiation at the end of the industrial process. Besides the inability to differentiate the product later, the aforementioned known pressure cooker designs also cannot benefit from flexible and decentralized industrial organization.
[0021] Therefore, the object of the present invention is to overcome the various deficiencies listed above and to propose a novel food pressure cooking appliance with a particularly simple and low-cost design that allows for particularly easy and flexible manufacture, simplifies the cleaning and storage of the appliance, as well as possible maintenance, while making it easy to upgrade.

[0026] Another object of the present invention is to provide a novel food pressure cooking appliance that provides a high level of safety in use.
[0027] Another object of the present invention is to provide a novel food pressure cooking appliance that is particularly ergonomic and has significant comfort for use.
[0028] Another objective of this invention is to provide a novel food pressure cooking appliance that is particularly easy to use.
[0029] Another object of the present invention is to provide a novel food pressure cooking appliance that is easy to store and can be washed in a dishwasher.

[0032] - A bayonet-type locking system is configured to ensure the lid is locked and unlocked relative to the bowl by rotating the lid relative to the bowl.
[0033] A support member is attached to the cover so that the cover can rotate relative to the support member about a first rotation axis between two positions corresponding to an unlocked mode and a locked mode, respectively.
[0034] - A manually operable locking / unlocking control component, for attachment to the support via a mechanical connection, to allow manual movement of the control component relative to the support.

[0058] As shown in the accompanying drawings, the present invention relates to a food pressure cooking appliance 1, which ensures cooking of various foods at a pressure level above atmospheric pressure when steam (e.g., water vapor) is present. The steam is generated by heating a cooking liquid (e.g., an aqueous liquid) within the appliance 1 containing the food. The appliance 1 according to the invention is preferably intended for home use; however, it should be understood that the invention can also relate to professional or semi-professional appliances. The appliance 1 according to the invention is designed to pressurize only in the presence of an integrated or external heating source, without increasing external pressure. Therefore, the food pressure cooking appliance 1 forms a pressure cooker, preferably intended to be placed on a separate cooking plate to heat its contents. The cooking appliance 1 according to the invention includes at least one bowl 2 forming a cooking container for holding the food to be cooked, and has a general rotational symmetry about a vertical central axis X-X' extending in a direction similar to the vertical direction in which the appliance 1 is normally operated (i.e., placed on a horizontal surface). The bowl 2 is typically made of a metallic material such as stainless steel or aluminum. The bowl 2 includes a bottom 2A, which is, for example, a bottom of multiple layers of heat conductors. Bowl 2 also includes an annular sidewall 2B that rises between the bottom 2A and the free upper edge 2C, is circular in shape here, and defines an opening for access to the interior of bowl 2. The construction of the free upper edge 2C will be described in more detail below in conjunction with the locking mechanism of the appliance 1. Advantageously, as shown in the figures, the cooking appliance 1 includes at least one bowl handle 2D, which is attached to the bowl 2 in a manner that projects outward from the bowl. In the embodiment shown in the figures, the bowl handle 2D is mounted on the outer surface of the sidewall 2B of bowl 2 so as to extend radially to the outer side of bowl 2, thereby forming a handle for the user to manually operate bowl 2 (e.g., lift and move the bowl). In the embodiment shown in the figures, the cooking appliance 1 includes two identical handles 2D, 2E, which are attached to the sidewall 2B of bowl 2 in a diametrically opposed manner relative to the central axis X-X', and the bowl handles 2D, 2E are located near the free upper edge 2C of bowl 2. However, it is entirely conceivable that bowl 2 may have only one bowl handle, or more than two bowl handles (e.g., three or four), without departing from the framework of the invention.
[0059] The appliance 1 according to the invention also includes a lid 3, designed to be associated with and locked relative to the bowl 2 to form a cooking chamber suitable for pressure rise, i.e., a cooking chamber sufficiently airtight to allow pressure rise of the appliance 1. To achieve this sealed, airtight property, the appliance 1 advantageously includes a sealing gasket (not shown), preferably a flexible annular gasket made of an elastomer, for example, for insertion between the lid 3 and the bowl 2, thereby preventing any uncontrolled leakage of steam and / or air between the interior and exterior of the chamber. The lid 3 is typically made of a metallic material such as stainless steel or aluminum. Advantageously, it has a shape that matches the bowl 2, for example, a generally disc-shaped shape, and when added and locked to the bowl 2, it advantageously extends in a plane substantially parallel to the average plane extending from the bottom 2A of the bowl 2 (i.e., a substantially horizontal plane). The lid 3 has an inner surface 30 facing the bowl 2 and an opposing outer surface 31. In the embodiment shown in the figures, the lid 3 includes a disc-shaped covering element 3A whose shape and size match the opening defined by the free upper edge 2C of the annular sidewall 2B of the bowl 2. In this embodiment, the lid 3 also advantageously includes an annular band 3B, for example, which is generally cylindrical or truncated. In the embodiment shown in the figures, the annular band 3B is formed by a descending edge extending downward from the peripheral edge of the disc-shaped covering element 3A. In this embodiment, the lid 3 is intended to cover the top of the bowl 2 in a generally adjusted manner such that the annular band 3B surrounds the top of the annular sidewall 2B and the free upper edge 2C from the outside, while the disc-shaped covering element 3A abuts against the free upper edge 2C by a sealing gasket (not shown) and is inserted between the bowl 2 and the lid 3. However, it is entirely conceivable that, as an alternative, the annular band 3B is intended to be inserted into the bowl 2 so as to be surrounded and contained within the bowl 2 without departing from the framework of the invention.
[0060] The food pressure cooking appliance 1 according to the invention includes a pressure regulating device 4, preferably including a valve (e.g., a counterweight or spring-loaded valve) to maintain the pressure inside the cooking chamber at a setpoint level, which can be adjusted by the user (adjustable calibration valve). Advantageously, the pressure regulating device 4 is mounted on a cover 3, for example, to be carried by the cover. The pressure regulating device 4 is configured to maintain the pressure inside the cooking chamber at a substantially constant predetermined value (setpoint level), referred to as the working pressure, which exceeds a threshold of atmospheric pressure, for example, between about 10 and 120 kPa, preferably on the order of 100 kPa. The general operating principle of such a pressure regulating device is well known and therefore does not need to be described in more detail herein. The food pressure cooking appliance 1 may of course include other operating components, such as an activation safety device 5 (which will be described in more detail below), an overpressure safety valve 6, etc.
[0061] The appliance 1 according to the invention also includes a bayonet-type locking system, which allows the cooking chamber formed by the lid 3 and the bowl 2 to reach at least the aforementioned working pressure without the risk of the lid 3 detaching under the pressure inside the cooking chamber. In other words, the locking system is designed to ensure that the mechanical connection between the bowl 2 and the lid 3 is sufficiently secure to prevent the lid 3 from separating from the bowl 2 under increased pressure inside the cooking chamber. More precisely, the bayonet-type locking system is designed to ensure the locking and unlocking of the lid 3 relative to the bowl 2 by rotating the lid 3 relative to the bowl 2, here about the vertical central axis X-X', and then allowing the appliance 1 to exit a locked waiting mode (where the lid 3 is freely placed on the bowl 2, as...). Figure 1 Switch to locking mode (where bowl 2 and lid 3 interact to prevent them from separating freely, as shown in the image). Figure 10 Conversely, in the embodiment shown, the utensil 1 switches from a locked-waiting mode to a locked mode by rotating the lid 3 relative to the bowl 2 about the central axis XX' in a first direction along a predetermined angular travel (e.g., between 10° and 30°, preferably between 10° and 20°, e.g., 15°). Conversely, the utensil 1 switches from a locked mode to a locked-waiting mode by rotating the lid 3 relative to the bowl 2 about the central axis X-X' in a second direction (opposite to the first direction) along the predetermined angular travel. To achieve this, the bayonet-type locking system of the cooking utensil 1 advantageously includes a first series of protrusions 7A-7J and a second series of protrusions 8A-8J, which respectively engage with the lid 3 (see Figure 1). Figure 5 ) and bowl 2 (see Figure 2The lid 3 is integral with the bowl 2 and is designed to engage and disengage with each other by rotating the lid 3 relative to the bowl 2 along the predetermined angular travel about the vertical central axis X-X', thereby ensuring the locking and unlocking of the lid 3 relative to the bowl 2. It is well known that the protrusions 7A-7J, 8A-8J of each of the first and second series are designed to engage in pairs, that is, by rotating the lid 3 relative to the bowl 2, each protrusion in one series will travel under the corresponding protrusion in the other series, thereby locking the lid 3 relative to the bowl 2. In the embodiment shown, the first series of protrusions 7A-7J integral with the lid 3 project radially toward the inner side of the lid 3, while the second series of protrusions 8A-8J integral with the bowl 2 project radially toward the outer side of the bowl from the outer surface of the sidewall 2B of the bowl 2. However, it is entirely conceivable that the locking protrusions 7A-7J on the lid 3 project outwards towards the lid 3, while the protrusions 8A-8J on the bowl project radially inwards towards the bowl. Therefore, the present invention is not limited to the specific construction of the locking ramps (formed by protrusions 7A-7J and 8A-8J) of the bayonet system. The key is that the lid protrusions 7A-7J and bowl protrusions 8A-8J, which respectively form the ramps on the lid and bowl, engage with each other through the relative rotation of the bowl 2 and lid 3 (here about the vertical central axis X-X'), such that the ramp on the lid reaches below the ramp on the bowl, forming a mechanical connection between the bowl 2 and lid 3 capable of resisting internal pressure within the cooking chamber. In the example shown, each lid protrusion 7A-7J consists of a volume element obtained through local volumetric deformation of the constituent material of the lid 3 shell, more precisely, local volumetric deformation of the annular band 3B, which the protrusions 7A-7J are preferably arranged along the annular band at regular or irregular intervals. Each protrusion thus forms a protrusion integral with and protruding from the annular band 3B, by defining a convex inner surface on one side and an opposite concave outer surface on the other, corresponding, for example, the application marks of a forming tool, preferably a drawing tool. However, the present invention is by no means limited to the implementation of specific protrusions 7A-7J, particularly those obtained by stretching as shown in the example. For example, it is entirely conceivable that the lid protrusions 7A-7J are formed by a tongue obtained by partially folding inward the free edge of the annular band 3B of the lid 3. In the example shown, the bowl protrusions 8A-8J are formed by an annular edge projecting outward from the free upper edge 2C, through which slots 9A-9J are formed to allow the lid protrusions 7A-7J to pass. The extension of the annular edge between each slot 9A-9J forms a respective movable ramp on the bowl for engaging with the lid protrusions 7A-7J forming the movable ramp on the lid. Thus, when the lid 3 covers the bowl 2, the lid protrusions 7A-7J can reach below the annular edge through the slots 9A-9J.Then, the appliance 1 is in a pre-locked mode (also known as a lock-waiting mode), which can be switched to a locked mode by simply rotating the lid 3 relative to the bowl 2 around the vertical central axis X-X'. This has the effect of angularly offsetting the protrusions 7A-7J on the lid 3 and the slots 9A-9J on the annular edge, thus providing a "bayonet" lock.
[0062] According to the invention, the appliance 1 further includes a support 10, which is used in a removable manner ( Figures 1 to 12 ) or permanent ( Figures 13 to 18 The lid 3 is attached to the support 10, allowing it to rotate relative to the support 10 about a first rotation axis Y-Y' (which coincides with the vertical central axis X-X' when the lid 3 is placed on the bowl 2) between two positions corresponding to an unlocked mode and a locked mode, respectively. The rotatable connection between the lid 3 and the support 10 can be implemented in any known manner. The two positions where the lid 3 can rotate relative to the support 10 are divided by a predetermined angular travel, which corresponds to the movement of the appliance 1 from... Figure 1 The pre-locked mode (lock wait mode) shown is switched to, for example... Figure 10 and Figure 13 The required travel for the lock mode shown.
[0063] Preferably, the appliance 1 includes a lid portion 300, which includes both the lid 3 and at least the support member 10. The lid portion 300 in an unlocked mode (i.e., the lid 3 is in a position corresponding to the unlocked mode relative to the support member 10) is designed to be combined with the bowl 2 according to at least one predetermined relative arrangement, the at least one predetermined relative arrangement corresponding to the aforementioned pre-locking mode of the appliance 1, thereby allowing the bayonet locking system to lock the lid 3 to the bowl 2 by rotating the lid 3 about the first rotation axis Y-Y', so that the lid portion 300 can switch from the unlocked mode to the locked mode. In other words, according to... Figure 1 The predetermined relative arrangement shown (pre-locked mode) combines the lid 300 in the unlocked mode with the bowl 2, resulting in an interlock between the support 10 and the bowl 2. This prevents the support 10 from rotating about the vertical central axis X-X' when placed on the bowl 2. The locking of the relative angular position between the support 10 and the bowl 2 allows the support 10 to function as a fixed frame that is immovable relative to the bowl 2, while the lid 3 can rotate about the vertical central axis along a predetermined angular stroke to move from the unlocked state (e.g., ...). Figure 1 (as shown) Switch to locked state (as shown) Figure 10 and Figure 13 (as shown in the image).
[0064] Advantageously, the support member 10 and the bowl 2 are respectively provided with complementary support structures 12, 13 and bowl structures 14, 15, which are arranged in a predetermined relative arrangement when the cover portion 300 and the bowl 2 are in the unlocked mode. Figure 1 The support structures 12 and 13 and the bowl structures 14 and 15 are preferably assembled together to fit together. The complementary support structures 12 and 13 and the bowl structures 14 and 15 are assembled together in such a way that the relative angular positions of the support member 10 and the bowl 2 can be locked in the horizontal plane, that is, in the plane perpendicular to the vertical central axis X-X'.
[0065] In the embodiment shown, the bowl 2 has two bowl structures 14, 15 arranged diametrically opposite to the vertical central axis X-X'. These two bowl structures 14, 15 are advantageously constructed of components having, for example, a generally C-shaped profile, as shown. The C-shaped components are, for example, carried by bowl handles 2D, 2E, and / or belong to the bowl handles. Advantageously, the support 10 includes two support structures 12, 13, each with a shape complementary to the shape of the bowl structures 14, 15. The two support structures 12, 13 are advantageously arranged diametrically opposite to the first axis of rotation Y-Y' on the lid 3, and the support structures 12, 13 advantageously project radially from the lid 3 to mate with the complementary bowl structures 14, 15. However, without departing from the framework of the invention, it is entirely conceivable that the support 10 and the bowl 2 are respectively provided with a single support structure and a single bowl structure, or even that the support 10 and the bowl 2 are configured to have interlocking elements of another nature based on another type of mating implementation (such as friction, clamping, magnetic attraction, etc.) to lock the relative angular positions of the support 10 and the bowl 2, instead of corresponding support and bowl structures for mating with each other by assembly. Advantageously, each bowl structure 14, 15 forms a female part, while each support structure 12, 13 forms a male part complementary to the female part, which is advantageously used to insert into the female part to establish a connection that prevents rotation between the support 10 and the bowl 2 about the vertical central axis X-X'.
[0066] Advantageously, the support 10 includes a crossbar 100, preferably attached to the cover 3 by a swivel connector, extending longitudinally between two opposing ends, which are preferably free ends. The crossbar 100 is advantageously formed from a generally elongated member extending diametrically on the cover 3. As shown, the opposing ends of the crossbar 100 forming the support 10 project radially from the cover 3 to form the support structures 12, 13, which are configured to mate with complementary receiving portions forming the bowl structures 14, 15, respectively. For example, the crossbar 100 is in the form of a single rigid metal strip with fins (such as...) formed at its free ends. Figure 1Examples up to 12) or the falling edge (such as Figures 13 to 18 (In one embodiment), support structures 12 and 13 are formed, which are complementary to the receiving portions of bowl structures 14 and 15, and the bowl structures are defined by C-shaped components integral with the bowl 2.
[0067] Therefore, the lid portion 300 forms a separate integral element, intended to be associated with the bowl portion 400 (formed by the bowl 2 itself and at least the bowl handles 2D, 2E, and the bowl structures 14, 15 advantageously carried by the bowl handles) to form a cooking chamber. In other words, when the lid portion 300 is in the unlocked mode, the lid 3 and the support 10 are positioned relative to each other such that the support 10 mates with the bowl 2 in a predetermined position, corresponding to the predetermined relative arrangement, to allow the movable ramps 7A-7J on the lid to separate from the slots 9A, 9J of the movable ramps on the bowl, travel below the movable ramps 8A-8J on the bowl, and then the lid portion 300 covers the bowl 2 in the waiting position. Then, rotating the lid 3 relative to the bowl 2 from the waiting position is sufficient to lock the lid 3 relative to the bowl 2. In other words, once the bowl 2 and the lid portion 300 are in the unlocked mode, and according to... Figure 1 When combined with the predetermined relative pre-locking arrangement shown, as long as the support 10 is held in position relative to the bowl 2 and the lid 3 is rotated relative to the support 10 along the predetermined angular travel, it is sufficient to make the movable ramps 7A-7J on the lid correspond to and be below the movable ramps 8A-8J on the bowl, thereby locking the lid 3 relative to the bowl 2.
[0068] According to the invention, the cooking appliance 1 includes a manually operable locking / unlocking control component 11, that is, it is configured to be directly operated by the user to allow the user to control the bayonet locking system so that it is advantageously possible to switch from an unlocked mode to a locked mode and vice versa by manually operating the control component 11. Therefore, the control component 11 advantageously allows the appliance 1 to be controlled from its pre-locked mode (…). Figure 1 To locked mode Figure 10 and Figure 13 The control component 11 is advantageously movably mounted relative to the support 10 between a first position and a second position, respectively corresponding to the unlocking and locking of the lid 3 relative to the bowl 2. More precisely, the control component 11 is mechanically attached to the support 10 in a permanent (as shown) or removable manner, the mechanical connection allowing the control component 11 to switch relative to the support 10 between the unlocking (as shown) and locking (as shown) positions of the lid 3 relative to the bowl 2. Figure 1 ) and locking ( Figure 10 and Figure 13The control element 11 can be manually moved between a first position and a second position. In other words, the control element 11 is advantageously attached to the support 10 in a removable or permanent manner while maintaining mobility relative to the support, allowing the user to manually move the control element 11 relative to the support 10 from the first position to the second position, and vice versa.
[0069] The appliance 1 according to the invention further includes means for converting manual movement of the control member 11 into rotation of the lid 3 relative to the support member 10. In other words, the control member 11 is connected to the lid 3 via a conversion device. Thus, the user can control the switching from an unlocked mode to a locked mode and vice versa by manually moving the control member 11 relative to the support member 10 between its first and second positions. Therefore, the conversion device is configured to convert movement of the control member 11 relative to the support member 10 into rotational movement of the lid 3 relative to the same support member 10 about a first rotation axis Y-Y', such that once the lid 3 is placed on the bowl 2 and the movable ramps 7A-7J on the lid are below the movable ramps 8A-8J on the bowl, the user can control its locking / unlocking by simply manipulating the control member 11 to rotate the lid 3 relative to the support member 10. Due to the interaction between the support 10 and the bowl 2 (which is advantageously achieved through the cooperation between the support structures 12, 13 and the bowl structures 14, 15), the control component 11 prevents the support 10 from rotating relative to the bowl 2 about the vertical central axis X-X' when it moves between its first and second positions (or vice versa).
[0070] As shown in the figure, the conversion device includes at least one drive structure 18, 19 and at least one driven structure 16, 17. The drive structure is carried by a manual control component 11, and the driven structure is connected to the cover 3 and engaged by the drive structure 18, 19. Figures 1 to 12 In the first embodiment, on one hand, the conversion device includes two driven structures 16 and 17, which are connected to the cover 3 and positioned far apart from each other; on the other hand, the conversion device includes two driving structures 18 and 19, which are far apart from each other and are both carried by the control component 11, preferably located at different positions on the control component. Figures 13 to 18 In the second embodiment, the conversion device includes a single driven structure 16 engaged with a single driving structure 18. Of course, the invention is not limited to a specific number of driving and driven structures, nor is it limited to a specific shape of the driving and driven structures.
[0071] exist Figures 1 to 12In the first embodiment, the appliance 1 includes a detachable connection device 42 that ensures a detachable mechanical connection between the control component and each drive structure 18, 19, to provide the possibility of relative movement between the control component 11 and each drive structure 18, 19 it carries under certain abnormal conditions. The detachable connection device 42 will be described in more detail below. Figure 13 to Figure 18 In the alternative embodiment shown, each drive structure 18 is integral with the control component 11 and forms a single, identical integral part with the control component 11, such that there is no possibility of relative movement between the control component 11 and the drive structure 18.
[0072] Advantageously, one of the driven structures 16, 17 and the driving structures 18, 19 forms a female structure, while the other of the driven structures 16, 17 and the driving structures 18, 19 forms a male structure for reception within the female structure. Advantageously, each male structure is slidable within the female structure that correspondingly accommodates it in a sliding direction substantially parallel to the first axis of rotation Y-Y', i.e., advantageously in a vertical sliding direction. In this preferred embodiment, each female structure is, for example, in the form of a cavity or an elliptical cavity, which ensures longitudinal guidance of the male structure inserted therein while allowing the male structure to rotate on its own. This arrangement is very simple and reliable, and allows the control component 11 to be rotatably mounted about a second axis of rotation different from the first axis of rotation Y-Y'.
[0073] like Figures 1 to 12In the example shown, when the conversion device includes a plurality of driven structures 16, 17 for cooperating with a plurality of matching drive structures 18, 19, one of the plurality of driven structures 16, 17 and the plurality of drive structures 18, 19 forms a plurality of female structures, while the other of the plurality of driven structures 16, 17 and the plurality of drive structures 18, 19 forms a plurality of male structures, each for being housed within a corresponding female structure. In the example shown, each male structure is formed by a drive structure 18, 19, while each complementary female structure housing the male structure is formed by a driven structure 16, 17. However, without departing from the framework of the invention, the opposite structure is preferably conceivable. Advantageously, the cooperation between each drive structure 18, 19 and each corresponding driven structure 16, 17 is reversible, that is, the driven structures 16, 17 and the drive structures 18, 19 can advantageously be interconnected and disconnected, for example, under the influence of user operation of the appliance 1. In other words, when the driven structures 16, 17 and the drive structures 18, 19 are connected to each other, i.e., when each driven structure 16, 17 engages with its corresponding drive structure 18, 19, a drive mechanism is formed that allows a rotational force to be applied to the cover 3 in response to movement of the control component 11 under the influence of manual operation by the user. In the example shown, each drive structure 18, 19 is advantageously formed by a stud, while each driven structure 16, 17 is formed by a matching cavity accommodating the corresponding stud. However, the invention is by no means limited to this particular example, and as an alternative, it is preferably conceivable that each drive structure is formed, for example, by a gear, and each driven structure by a rack that meshes with said gear.
[0074] According to the preferred embodiment shown in the accompanying drawings, the control component 11 is advantageously rotatably mounted relative to the support 10 about a second rotation axis Z-Z'. Preferably, for ergonomic control, the second rotation axis Z-Z' is parallel to the direction intersecting the first rotation axis Y-Y', and preferably perpendicular to the first rotation axis Y-Y', as shown in the drawings. Advantageously, the control component 11 is rotatably mounted relative to the support 10 between two positions: on the one hand, an extended position corresponding to the unlocking mode (the first position described above), wherein the control component 11 protrudes vertically outward directly above the cover 3; on the other hand, a retracted position corresponding to the locking mode (the second position described above), wherein the control component 11 moves downward toward the cover 3. Preferably, in its extended position, the control component 11 extends along an average direction substantially parallel to the vertical central axis X-X' (and the first rotation axis Y-Y'), while in the retracted position, it advantageously extends along an average direction substantially perpendicular to the vertical central axis X-X', as shown in the drawings. In this preferred embodiment, the control component 11 is therefore retractable, thereby allowing it to move to one side when in its retracted position.
[0075] Advantageously, as shown in the accompanying drawings, the control component 11 includes a handle 11A, which is therefore in the form of an arched component, having a ring-shaped or arched shape, constructed in a manner that allows the user to grip firmly, preferably in a manner that allows for full hand gripping or at least between the thumb and several fingers. Of course, the invention is not limited to the implementation of a handle to form the control component 11; alternatively, it can be formed by, for example, a generally straight lever, or have a T-shaped, L-shaped profile, a saddle-shaped, or flared knob, etc. The handle 11a extends between two ends 110, 111 through which the second axis of rotation Z-Z' passes. In other words, the handle 11A advantageously has a generally U-shaped or C-shaped shape and is hinged relative to the support 10 at the ends 110, 111.
[0076] Preferably, the at least one drive structure 18, 19 is carried by one of the ends 110, 111.
[0077] like Figures 1 to 12 In the illustrated embodiment, the two ends 110, 111 thus each carry drive structures 18, 19. For example, each end 110, 111 of the handle 11A advantageously forms a corresponding ear 110A, 111A, which carries, for example, a corresponding pin 110B, 111B, which engages with corresponding bearings 21A, 21B for rotatably mounting the handle 11A about a second axis of rotation Z-Z'. The bearings 21A, 21B are themselves advantageously attached to the support 10 by any suitable means (threaded connection or otherwise). As shown in the figures, each ear 110A, 111A advantageously has an inner surface arranged toward the inside of the handle, an inner surface facing the other ear, and an opposing outer surface, from which the corresponding pins 110B, 111B extend coaxially outward to the second axis of rotation Z-Z'. Figures 1 to 12 In the illustrated embodiment, each drive structure 18, 19 is carried by a corresponding intermediate part 18A, 19A rotatably mounted on the corresponding ear 110A, 111A about a second axis Z-Z'. The rotatability of each intermediate part 18A, 19A relative to the corresponding ear 110A, 111A that carries it is advantageously prevented by a lock. The latter is formed, for example, by cavities 22 formed on the surface of each intermediate part 18A, 19A to form an impactor and corresponding bolts 23, 24 resiliently slidably mounted in each arm of the handle 11A, the bolts being located within corresponding receiving portions 23A, 24A formed by cavities opening at the corresponding ears 110A, 111A. This reversible lock is advantageously part of the aforementioned detachable connection device 42. It allows for a disengagement function, which will be disclosed in more detail below.
[0078] As an alternative, according to Figures 13 to 18 In the embodiment shown, the drive structure 18 (the only one) is carried by a single end 111 and is integral with the inner surface of the handle 11A that carries it by projecting inward.
[0079] According to the invention, the appliance 1 includes a control module 200 removably attached to the cover 3. As its name suggests, the control module 200 at least partially carries one or more means for commanding or controlling the operation of the appliance 1. Preferably, the control module 200 carries the support member 10.
[0080] The control module 200 can be removably attached to the cover 3 by any known means, such as by a resilient fitting, a threaded connection (as shown in the example), or any other mechanical fastening method. For example, the appliance 1 includes a mounting rod 27, which is advantageously carried by and protrudes from the control module 200. The appliance 1 also includes a central fastening hole 29 formed through the cover 3, and if the rod 27 is tightened at least toward its free end, the rod 27 will pass through the hole to attach the control module 200 to the cover 3, for example, by engaging with a nut 32.
[0081] More precisely, the control module 200 carries at least one first subset 200A, which includes at least the pressure regulating device 4 and the driven structures 16, 17. In other words, the control module 200 is an integral component, itself including the first subset 200A, and itself carrying the pressure regulating device 4 and the at least one driven structure 16, 17. Due to the detachability of the control module 200, the pressure regulating device 4 and the at least one driven structure 16, 17 can be separated from the cover 3. This facilitates cleaning of the cover 3, which can be washed underwater or placed in a dishwasher without the risk of damaging the pressure regulating device 4, a potentially fragile technical component, and is designed for safety. Furthermore, since the control module 200 also supports at least a portion of the conversion mechanism, that is, at least a portion of the mechanism enables manual movement of the control member 11 to be converted into rotation of the cover 3 relative to the support member 10, the user cannot control locking / unlocking when the control module 200 is separated from the cover 3. In fact, in this case, manual movement of the control member 11 cannot be applied to the cover 3 as a driving torque. This allows for limiting the risk of misuse of appliance 1 even without control module 200. Similarly, since pressure regulator 4 is supported within control module 200, lid 3 cannot form an airtight cooking chamber with bowl 2, because leakage hole 38 is not connected to pressure regulator 4 when control module 200 is separated from lid 3. This also helps ensure the safety of appliance 1 when lid 3 is not in use with control module 200.
[0082] Advantageously, the device for converting manual movement of the control component 11 into rotation of the cover 3 includes a hub 25 designed to be attached to the cover 3, coaxial with the first axis of rotation Y-Y', the hub 25 carrying at least one driven structure 16, 17, as shown in the embodiment illustrated in the figures. As shown in the figures, the hub 25 preferably forms the at least one driven structure 16, 17 around its periphery. Thus, each driven structure 16, 17 is advantageously carried by the hub 25 and forms a single, identical integral part with the hub. The hub 25 is designed to be attached directly or indirectly to the cover 3, preferably without rotation between the cover 3 and the hub 25, so that any force driving the hub 25 about the first axis of rotation Y-Y' is directly transmitted to the cover 3. Advantageously, the hub 25 forms a cap, which helps to define a receiving portion for accommodating the pressure regulating device 4. For this purpose, the hub 25 has, for example, a bell-shaped form, having an upper wall 25A and annular sidewalls 25B, on which at least one ( Figure 13 Up to 18) or two ( Figures 1 to 12 The device 1 extends vertically and forms elongated cavities for the driven structures 16, 17. The pressure regulating device 4 is advantageously arranged at least partially below the cap 25, i.e., below the upper wall 25A, which allows it to be concealed when placed near the center of the cover 3, i.e., at the position of minimum rotational travel relative to the support 10. This arrangement facilitates the insertion of complementary functional elements that readily engage with, for example, the pressure regulating device 4, and are arranged for this purpose, for example, on the upper wall 25A. Advantageously, the device 1 also includes a disc 26 designed to be arranged on the cover 3 and below the hub 25, preferably forming, together with the hub, the receiving portion for accommodating the pressure regulating device 4. The disc 26 is preferably advantageously permanently attached to the hub 25 and preferably removably attached to the cover 3, transmitting the rotational force about the first axis Y-Y' to the cover through the engagement between the drive structures 18, 19 carried by the hub 25 and the driven structures 16, 17. Therefore, the pressure regulating device 4 is advantageously supported by the disc 26, while being at least partially covered by the hub 25.
[0083] Advantageously, the first subset 200A includes the disc 26, and is therefore also carried by the control module 200. Thus, the disc 26 and the hub 25 advantageously form a single housing in which the pressure regulating device 4 is arranged, and the single housing also forms one or more driven structures 16, 17 on the sidewall 25B of the hub 25, which are used to engage with the drive structures 18, 19 when the control module 200 is placed on and attached to the cover 3.
[0084] Advantageously, the appliance 1 includes a second subset 200B, comprising at least a control element 11, the at least one drive structure 18, 19, and a support 10. The second subset 200B is advantageously configured for rotational mounting relative to the first subset 200A about the first rotation axis Y-Y'. In the embodiment shown in the figures, the relative rotation of the first subset 200A and the second subset 200B is controlled by manually operating the control element 11 to move the control element relative to the support 10.
[0085] like Figures 1 to 12 In the first embodiment shown, the first subset 200A and the second subset 200B are permanently connected to each other so that they advantageously form the control module 200.
[0086] According to such Figures 13 to 18 In the second embodiment shown, the first subset 200A and the second subset 200B are removably connected to each other.
[0087] This invention relates to several scenarios, and specifically to the following scenarios:
[0088] - In addition to the first subset 200A, the control module 200 also carries a second subset 200B. The alternative itself can be the first sub-alternative, according to which the first subset 200A and the second subset 200B are permanently attached to each other, for example... Figures 1 to 12 In the appliance 1 shown, the first subset 200A and the second subset 200B are not intended to be detachable from each other. According to the second sub-alternative, the first subset 200A and the second subset 200B are removably connected to each other, and not only can the control module 200 be removed from the cover, but the first subset 200A and the second subset 200B constituting the control module 200 are also detachable from each other.
[0089] - The control module 200 only carries a first subset 200A, which is removably attached to a second subset 200B, the second subset itself being permanently attached to the cover 3, for example. Figures 13 to 18 In the alternative embodiment shown, the second subset 200B is permanently attached to the cover 3 but is movable relative to the cover (e.g., by means of a pin and sliding system not shown), while the first subset 200A forming the control module 200 is removably attached to the second subset 200B.
[0090] It should be noted that the latter embodiment is particularly advantageous when implemented using a control component 11 formed by a rotating handle, with a first subset 200A arranged between its two ends, where the control module 200 is formed. In practice, in this case, the module 200 is more difficult to separate from the second subset 200B when the handle 11A is extended (unlocked position) than when it is folded down (locked position). Therefore, the user is encouraged to fold the handle 11A down to separate the first subset 200A from the second subset 200B. This locks the integral subset formed by the second subset 200B and the lid 3, preventing the user from repositioning the lid 3 on the bowl 2 to its functional position. This provides additional safety. In fact, in order to return the lid 300 to the unlocked mode, the user will first have to reinstall the control module 200 (formed here by the first subset 200A) and then lift the handle 11A, which will cause the hub 25 to rotate. The hub itself causes the lid 3 to rotate from its locked mode to the unlocked mode, thereby allowing the lid 3 to be positioned properly on the bowl 2.
[0091] like Figures 1 to 12 In the first embodiment shown, preferably, the crossbar 100 forming the support 10 is arranged between the disc 26 and the hub 25, such that the crossbar 100 and the sub-assembly formed by the disc 26 and the hub 25 have relative rotatability about a first axis of rotation Y-Y'. Preferably, the hub 25 is attached to the disc 26, for example, by a threaded connection, a resilient fitting, or any other means, wherein the crossbar 100 is positioned and engaged between the hub 25 and the disc 26. Figures 13 to 18 In the second embodiment shown, the crossbar 100 is arranged oppositely below the disc 26 so as to be between the cover 3 and the disc 26.
[0092] In any case ( Figures 1 to 12 ,or Figures 13 to 18 The hub 25 and disc 26 thus form a first subset 200A, while the control component 11 and crossbar 100 form a second subset 200B. The first subset 200A and the second subset 200B are assembled to each other in a manner that allows them to rotate relative to each other about a first axis of rotation YY'. The pressure regulating device 4 belongs to the first subset 200A because it is preferably carried by the disc 26. For example, the disc 26 may take the form of a cup, preferably made of plastic material, which has a hole 26A for being arranged coaxially with the central hole 29 through the lid 3. The cup 26 advantageously has a lower surface 260 for facing the outer surface 31 of the lid 3, and an opposing upper surface 261. A valve hole is arranged through the cup between its lower surface 260 and upper surface 261. The hole is sealed on the lower surface 260 by a gasket 33. Figures 13 to 18(An alternative not shown) surrounds and opens on one side of the upper surface 261 to enter chamber 34, which communicates with well section 35 on one side and exhaust pipe 36 on the other. Well section 35 accommodates a valve device with a counterweight or loading spring (in Figures 13 to 18 (Not visible in the alternative options), the device is equipped with a movable valve 37, which is slidably mounted in a direction parallel to the first axis of rotation Y-Y'. The valve 37 returns to a lower position (under the force of gravity or an elastic body such as a spring). The valve 37 passes through a hole provided in the cup body forming the disc 26 to close a leakage hole 38 formed through the cover 3. Due to the sealing gasket 33, the leakage hole 38 is in airtight communication with the chamber 34. Therefore, the valve 37 is sensitive to the pressure inside the cooking chamber and alternately closes or releases the leakage hole 38 to regulate the pressure level inside the cooking chamber. When the pressure level inside the cooking chamber exceeds a predetermined working pressure, the valve 37 rises, which allows the steam contained in the cooking chamber to first reach the chamber 34 and then be discharged outward through the exhaust pipe 36. The appliance 1 also includes a calibration device for calibrating the pressure regulating device 4, which allows adjustment of the working pressure level of the trigger valve 6, i.e., pushing the valve 37 out of its return position to release the pressure threshold of the leakage hole 38. The calibration device can be of any known type (e.g., compression of the return spring acting on valve 37), and is advantageously connected to the manual control device 39. The manual control device 39 is, for example, in the form of a tab mounted rotatably about a first axis of rotation Y-Y' and extending between its two ends, one end of which is connected to the valve, advantageously forming the pressure regulating device 4 for calibration, and the other end connected to a slider (…). Figures 1 to 12 Alternative options), knob ( Figures 13 to 18 (An alternative), or a manual lever. According to... Figures 1 to 12 In the illustrated embodiment, the tab passes through, for example, the sidewall 25B of the hub 25, by passing through a groove 250 provided in the sidewall 25B. Figures 13 to 18 In the illustrated embodiment, the tab is held below the upper wall 25A of the hub 25, which has a groove 251 through which a control knob designed for manual operation is passed. Of course, the use of a scale-adjustable pressure regulating device 4 is entirely optional, and preferably, a regulating valve whose scale cannot be modified by the user is conceivable.
[0093] Advantageously, the conversion device includes first and second complementary drive components 43, 44, which are respectively carried by the first subset 200A and the cover 3, and are designed to cooperate with each other to allow rotational drive by the first subset 200A about the first axis of rotation Y-Y' of the cover 3. In other words, when the control module 200 is placed on and attached to the cover 3, the cooperation of the complementary drive components 43, 44 allows the first subset 200A to be rotatably fixed relative to the cover 3 about the first axis of rotation Y-Y'. For example, the first drive component 43 includes a stud integral with the disc 26 (and, for example, integral with the disc), and is arranged away from the first axis of rotation Y-Y'. The stud 43 advantageously protrudes toward the bottom of the lower surface 260 of the disc 26 and is designed to be inserted into a corresponding blocking hole 44 formed through the cover 3, and its dimensions match the dimensions of the stud 43. Thus, the blocking hole 44 forms the second drive component. Due to the engagement of the stud 43 and the blocking hole 44, the rotational force applied to the first subset 200A about the first rotation axis Y-Y', and thus to the disc 26, is transmitted to the cover 3 via the hub 25 connected to the disc 26. An O-ring (not shown) or any other sealing system is advantageously arranged around the stud 43 to prevent any accidental communication between the interior of the chamber and the outside through the blocking hole 44.
[0094] Advantageously, the first subset 200A supports the mounting rod 27, which, for example, protrudes from the disc 26, preferably downward and coaxial with the first axis of rotation Y-Y'. For example, the mounting rod 27 has an inner portion 27A arranged within the first subset 200A and passing through a hole 28 formed by the crossbar 100, about which the second subset 200B rotates, i.e., about the first axis of rotation Y-Y'. The mounting rod 27 also preferably has a threaded free portion 27B passing through a central fastening hole 29 formed by the cover 3, preferably at the center of the cover 3, where the threaded free portion 27B engages with the nut 32 (…). Figures 13 to 18 (Not shown) to attach the first subset 200A to the cover 3.
[0095] like Figures 1 to 12In the first embodiment shown, the mounting rod 27 is used to attach a first subset 200A and a second subset 200B to the cover 3, in which case the two subsets advantageously form a control module 200. In the first embodiment, the mounting rod 27 advantageously includes a flared head, while the hub 25 includes a tubular member 25C that extends substantially coaxially with the first axis of rotation Y-Y' and passes through a hole 28 formed by the support member 10 and a hole 26A formed by the disc 26, to abut against the outer surface 31 of the cover 3 coaxially with a hole 29 formed by the cover 3. The rod 27 is advantageously screwed into the tubular member 25C, which has a shoulder-shaped constriction, against which the head of the rod 27 abuts. Thus, the inner portion 27A is arranged on one side of the outer surface 31 of the cover 3, while the threaded free portion 27B passes through the central hole 29 formed by the cover 3 to engage with a nut 32. O-ring 40 or any other sealing system is threaded onto rod 27 to ensure airtightness when the second subset 200A is attached to cover 3.
[0096] like Figures 13 to 18 In the second embodiment shown, the mounting rod 27 is used only for reversibly mounting the first subset 200A (advantageously forming a separate control module 200) to the cover portion formed by the cover 3, and for permanently attaching the second subset 200B to the cover 3 by other means. In this case, the rod 27 passes through a hole 28 formed, for example, by the crossbar 100, to allow relative rotation between the first subset 200A and the second subset 200B about the rod 27 about a first axis of rotation Y-Y'.
[0097] The first subset 200A and the second subset 200B are advantageously assembled to form an integral control module 200, which is removably attached to the cover 3 by the assembly rod 27 and the nut 32.
[0098] Advantageously, the second subset 200B also includes a crown 41, which forms an upper annular cap having a central hole 41A. (As...) Figures 1 to 12 In the first embodiment, the crown 41 advantageously covers the disc 26, the crossbar 100, the carriers 21A and 21B, and the pins 110B and 111B, while exposing the hub 25 through its hole 41A. For example... Figures 13 to 18In the second embodiment shown, the crown 41 again forms an annular cover supporting the handle 11A, which is rotatably mounted relative to the crown 41. A first subset 200A, comprising at least a hub 25 and a disc 26, is inserted into a central hole 41A formed by the crown 41 and the downwardly folded handle 11A. In this case, the driven structure 16 is formed by a slot that opens freely at its lower end, allowing a stud advantageously forming the drive structure 18 to be slidably inserted into the slot when the first subset 200A is placed in the central hole 41A of the crown 41.
[0099] Advantageously, the aforementioned safety device 5 is sensitive to the pressure inside the cooking chamber. Therefore, it easily moves between different positions under the influence of the pressure level inside the cooking chamber. In particular, the safety device 5 easily occupies the blocking position (see...). Figure 11 and Figure 12 In the blocked position, when the pressure inside the cooking chamber is significantly higher than atmospheric pressure, or at least higher than a predetermined pressure level higher than atmospheric pressure, the safety device is activated to prevent the lid 3 from unlocking. Advantageously, the safety device 5 is at least partially and permanently mounted on the lid 3, i.e., supported on the lid, and thus forms a permanent component of the lid body 300. However, as an alternative, without departing from the framework of the invention, it is preferably conceivable that the safety device 5 is carried by a first subset 200A or a second subset 200B.
[0100] The safety device 5 is activated to engage with the second subset 200B in the blocking position, thereby fixing the cover 3 and the second subset 200B rotatably about the first rotation axis Y-Y'.
[0101] The safety device 5 includes, for example, a movable element 5A slidably mounted on the cover 3, which slides vertically between an upper position (stop position) and a lower position (return and stop position) along a sliding direction parallel to the vertical central axis X-X'. In the upper position, the movable element engages with a complementary blocking structure 5B (in this case, an orifice) carried by the support 10 to prevent rotation of the cover 3 relative to the support 10. In the lower position, the movable element does not interfere with the complementary blocking structure 5B, thus allowing free rotation of the cover 3 relative to the support 10. As shown in the figures, the movable element 5A is advantageously formed as a finger for vertical sliding within a tubular structure 5C connected to a leakage hole 5D formed through the cover 3. In the upper position, the finger hermetically seals the leakage hole 5D, while in the lower position, it allows steam to leak through the hole 5D. Furthermore, the observation window 41B is arranged through the crown 41 to allow the user to see the finger 5A when it is in the upper position, thus indicating a sufficiently high pressure level within the appliance 1, contradicting the secure unlocking of the lid 3. As long as the locked mode is not reached, the moving element 5A will not align with the hole 5B formed through the crossbar 100, and therefore will not move upward to reach its upper sealing position, as it thus becomes abutted against the underside of the crossbar 100 (see...). Figure 4 This constitutes a safety measure to prevent improper closure, and prevents pressure rise in appliance 1 as long as the locked mode is not reached.
[0102] Advantageously, the connecting device 42 can be detached (in Figures 1 to 12 In the alternative implementation, the control member 10 is configured such that when the control member 10 moves from its second position (corresponding to the retracted position in the locked mode) to its first position (corresponding to the extended position in the unlocked mode) and the safety device 5 is in its blocking position, the control member 10 and each drive structure 18, 19 are disengaged from each other, thereby allowing the control member 10 to move freely from its second position to its first position, while the drive structures 18, 19 do not apply any driving force to the driven structures 16, 17.
[0103] according to Figures 1 to 12 The embodiment shown includes at least the following components detachable from the connection device 42:
[0104] Each intermediate component 20 is carried by and rotatably mounted at one end of the handle 11A, whereby the control component 11 is formed.
[0105] - and bolts 23, 24, which are slidably guided by receiving portions 23A, 24A and housed within corresponding cavities (impactors) 22 formed on the surface of each intermediate component 20 to prevent rotation.
[0106] The detachable connection device 42 also includes a resilient return element (coil spring or other device, not shown), for example placed in each receiving portion 23A, 24A that receives each bolt 23, 24, to resiliently return each bolt 23, 24 to a locked position in which each bolt 23, 24 engages a corresponding cavity 22 disposed on the surface of the intermediate member 20 (see...). Figure 7 This prevents the intermediate component 20 from rotating relative to the handle 11A. When the safety device 5 is in the blocking position, and the user is still applying unlocking force to the handle 11A to move it from its retracted position (folded down on the cover) to its extended position, the hub 25 cannot rotate by inserting the finger 41B into the hole 5B of the crossbar 100. At this time, if the user continues to apply force to the handle 11A, the driving force he applies to the handle will overcome the restoring force applied to each bolt 23, 24 by the return spring, causing the bolt to be pushed out of the corresponding cavity 22, thus allowing the handle 11A to rotate relative to each stationary intermediate component 20. Therefore, the rotational movement of the handle 11A is no longer transmitted to each drive mechanism 18, 19, so that the hub 25 is not subject to any driving force. This separation avoids subjecting the locking / unlocking mechanism to unsuitable forces that could damage some components of the control mechanism. Then, the user can reassemble the handle 11A by simply returning it to the retracted position so that each bolt 23, 24 is aligned with the corresponding cavity 22, and is reinserted into the corresponding cavity 22 under the restoring force applied by the spring, so as to form a rotary drive connection around the second rotation axis Z-Z' of the drive structures 18, 19.
[0107] Advantageously, the second subset 200B carries the detachable connection device 42. This allows, for example, in... Figures 13 to 18 In one embodiment, the second subset 200B remains permanently attached to the cover 3 to maintain additional safety features permanently associated with the cover 3.
[0108] Therefore, the device 1 according to the present invention has a high level of safety and reliability.
