Abstract
Description
Technical Field
[0001] This invention relates to a cooking preparation appliance, particularly a juicer. Background Technology
[0002] Food preparation appliances ensure the preparation of food by squeezing, cutting, grinding, or slicing. These appliances are suitable for all types of food, whether fruits or vegetables, fish, or even meat. They are commonly used in the hotel and catering industry, for group meals, and also for private use. By way of non-limiting examples, food preparation appliances can include juicers and blenders for fruits and vegetables, citrus presses, cheese shredders, vegetable cutters, and even multi-functional robots.
[0003] In the case of a juicer, the juicer includes a fixed base and a rotating tool (usually a rotating basket) removably mounted on the fixed base, which is driven by a motor. The rotating tool includes a bottom forming the bottom of the grinder and sidewalls extending from the bottom, which constitute a sieve.
[0004] Additionally, a removable lid is provided, with an inlet opening to allow food, particularly fruits and vegetables, to be introduced. This lid covers the rotating basket, and especially the grinder, thus protecting the user from any contact with the grinder. During operation, the food remains in contact with the high-speed rotating grinder by a pusher operated by the user through the inlet opening.
[0005] Under these conditions, the food is chopped near the grinder. A sieve then allows the juice to flow while retaining the solid parts of the food. Centrifugal force then pushes the food towards the top of the basket, where it is collected in a container or bin. Additionally, any liquid juice that has passed through the sieve walls is collected in a juice tank.
[0006] This food preparation utensil includes a locking system to ensure that the rotating tool reliably brakes and stops when the user attempts to remove the removable lid. This prevents contact with the rotating tool while it is rotating, thus ensuring user safety.
[0007] FR-A-2 830 423 is known, describing this type of food preparation appliance in which the locking system includes a clamping handle that locks into a recess in a removable lid and is mounted on two clamping rods. Unlocking of the removable lid is performed by the user in two consecutive movements: first, by pivoting the handle upwards, and then by tilting the handle and rods toward the front of the appliance. Upon pivoting the handle upwards, a braking system is activated, thereby ensuring mechanical braking of the rotating tool and interrupting the power supply to the motor.
[0008] Overall, the locking system is satisfactory, reliable, and secure in use. However, the ergonomics of the locking system could be improved because its operation requires two successive movements, and when the removable cap is unlocked, the handle occupies a large space at the front of the appliance, thus obstructing access to the removable cap and juice container and cluttering the front of the appliance. Summary of the Invention
[0009] Therefore, the purpose of this invention is to provide an ergonomically improved food preparation appliance.
[0010] Therefore, the present invention relates to a food preparation apparatus, particularly a juicer, the food preparation apparatus comprising at least:
[0011] Base
[0012] Tools mounted on the base,
[0013] A removable cover, designed to be attached to the rest of the appliance to cover the tool.
[0014] A motor, mounted on the base, rotatable about a main axis and configured to drive the tool, and
[0015] The removable cover has a locking system on the base.
[0016] According to the present invention, the locking system includes:
[0017] Actuation device,
[0018] A first lever, disposed inside the base and rotatable relative to the base about a first lever axis, is configured to be driven by the actuating device to rotate about the first lever axis.
[0019] A first hook, configured to move via the first lever, and comprising:
[0020] The lower end is attached to the first lever so that it can rotate relative to the first lever about a second lever axis parallel to the axis of the first lever.
[0021] The top, and
[0022] The elongated central portion connects the lower end to the upper end.
[0023] In addition, the central portion of the first hook extends through the first opening of the base and is guided by the first opening of the base, enabling the first hook to:
[0024] The base slides between the locked and unlocked positions along its center portion relative to the base, and simultaneously
[0025] The base pivots between the locked and unlocked positions relative to the base about a first pivot axis parallel to the first lever axis and passing through the first opening of the base.
[0026] Therefore, by driving the first lever to rotate around the first lever axis through the actuation device, the device can operate between the following:
[0027] A locking configuration in which the first hook is in its locked position and in its locked orientation, and wherein the upper end of the first hook contacts the removable cover, thereby preventing the removal of the removable cover.
[0028] The unlocking configuration includes a first hook in its unlocked position and in its unlocked orientation, wherein the upper end of the first hook is spaced apart from the removable cover, thereby allowing the removable cover to be removed.
[0029] This invention improves the ergonomics of food preparation utensils. In particular, a single rotational movement of the first lever caused by the action on the actuation device is sufficient to unlock the food preparation utensils and allow the removal of the removable lid.
[0030] Specifically, the first hook is guided both by its attachment to the lower end of the first lever and by a first opening in the base, allowing the first hook to simultaneously slide and pivot through the opening. Therefore, rotation of the first lever causes an elliptical movement of the upper end of the first hook, enabling efficient and reliable engagement or disengagement of the upper end of the first hook with the removable cover. This elliptical movement is particularly advantageous because it simultaneously allows the upper end of the first hook to move away from the removable cover along the main axis, thereby unlocking the food preparation appliance, and to be spaced perpendicular to the main axis from the removable cover, allowing removal of the removable cover along the vertical axis without increasing the appliance's footprint or requiring empty space at the front of the appliance.
[0031] In other words, unlocking the appliance requires only a single movement of the actuating device, and once unlocked, the removable cap can be removed with a simple translational movement. Furthermore, the first hook does not obstruct the removal of the removable cap and juice container towards the front of the appliance. Additionally, the elliptical movement of the upper end of the first hook provides an easily perceptible visual indication of the appliance's locked or unlocked state, while also being aesthetically pleasing. Therefore, the appliance is easy to use with one hand.
[0032] According to other advantageous aspects of the invention, the food preparation apparatus includes one or more of the following features, either individually or in any technically possible combination:
[0033] The actuation device includes: a lever rotatable relative to a base about a lever axis between a locked position and an unlocked position; and a first link. The first link includes a first end and a second end, the first end being attached to the lever for rotation relative to the lever about a first link axis parallel to the lever axis, and the second end being attached to a first lever for rotation relative to the first lever about a second link axis parallel to the first lever axis and a third link axis parallel to the first link axis. The actuation device is configured such that rotation of the lever about its lever axis between its locked and unlocked positions drives rotation of the first lever about the first lever axis via the first link, and thus operates the appliance between the locked and unlocked configurations, wherein the appliance is in the locked configuration when the lever is in the locked position and the appliance is in the unlocked configuration when the lever is in the unlocked position.
[0034] The actuation device includes a handle attached to the rod and rotatable relative to the base about the rod axis, the handle being configured to drive the rod to rotate about the rod axis between its locked and unlocked positions.
[0035] The axis of the rod, the axis of the first link, and the axis of the third link are orthogonal to the height axis. In the locking configuration of the appliance, the rod is located along the height axis between the first end and the second end of the first link, and in the unlocking configuration of the appliance, the first end of the first link is located along the height axis between the rod and the second end of the first link. When the appliance is operated from its unlocking configuration to its locking configuration, the first end of the first link moves downward along the height axis while the rod moves upward, and when the appliance is operated from its locking configuration to its unlocking configuration, the first end of the first link moves upward along the height axis while the rod moves downward.
[0036] In the locking configuration of the device, the first link axis is located on a first side of a plane passing through the rod axis and the third link axis. In the unlocking configuration of the device, the first link axis is located on a second side of a plane passing through the rod axis and the third link axis, the second side being opposite to the first side. When the device operates between its unlocking configuration and its locking configuration, the device passes through an alignment configuration in which the first link axis passes through a plane that passes through the rod axis and the third link axis.
[0037] The lever is translatable relative to the base along the main axis between a release position and a braking position, and reaches the release position when the removable cover is installed on the rest of the appliance and when the lever is in its locked position. The appliance further includes a braking system capable of braking the rotation of the motor about the main axis. The braking system includes a braking device and a braking member. The braking device is rotatably fixed to the motor, and the braking member is attached to the lever so as to be rotatable relative to the lever about a lever axis and translatably fixed relative to the lever along the main axis. The translation of the lever between its release position and its braking position causes the braking member to operate between the release and braking positions. When the lever is in the release position, it reaches the release position, in which the braking member does not cooperate with the braking device, such that the braking system does not impede the rotation of the motor about the main axis. When the lever is in the braking position, it reaches the braking position, and in which the braking member cooperates with the braking device, such that the braking system impedes the rotation of the motor about the main axis.
[0038] The braking system further includes a reset member that applies a force along the main axis to the braking member and the lever, the force of which tends to return the lever to its braking position. When the removable cover is installed on the rest of the appliance, rotation of the lever from its unlocked position to its locked position causes the lever to translate from its braking position to its released position against the force applied by the reset member to the braking member and the lever. When the removable cover is not installed on the rest of the appliance, rotation of the lever from its unlocked position to its locked position does not cause the lever to translate from its braking position to its released position, and the force applied by the reset member to the braking member and the lever causes the first hook to slide beyond its locked position.
[0039] The braking device is a brake disc that is fixed to the rotation of the motor, and the braking component is a brake pad that extends parallel to the brake disc. In the braking position, the brake pad contacts the brake disc to impede the rotation of the motor around the main axis.
[0040] The base includes a rectangular hole extending along the main axis, and the rod extends through the rectangular hole in the base such that the base does not prevent the rod from translating along the main axis.
[0041] The device includes a guide that guides the braking component and rod to translate relative to the base along the main axis.
[0042] The ratio between the first distance measured between the first lever axis and the first pivot axis and the length of the first lever measured between the first lever axis and the second lever axis is between 1.5 and 4.5, preferably equal to 2.6.
[0043] The first hook has an angular displacement of 5° or more around the first pivot axis between its locked position and its unlocked position, preferably greater than or equal to 10°.
[0044] The angle between the center portion of the first hook and the height axis, measured in a plane perpendicular to the first pivot axis at the unlocking position of the first hook, is greater than or equal to 5°, preferably greater than or equal to 15°.
[0045] The linear displacement of the first hook along its central portion between its locked and unlocked positions is greater than or equal to 10 mm, preferably greater than or equal to 15 mm.
[0046] The appliance further includes a cutting device operable between an energized configuration and a cutting configuration, in which the motor is powered to drive the tool, and in the cutting configuration, the motor is not powered to prevent the tool from being driven. When the appliance is in a locked configuration, the cutting device is in the energized configuration; when the appliance is in an unlocked configuration, the cutting device is in the cutting configuration. The appliance can also operate in an intermediate configuration by actuating a first lever to rotate about its axis, reaching this intermediate configuration between the locked and unlocked configurations. In this intermediate configuration, the upper end of the first hook contacts a removable cover, thereby preventing removal of the removable cover, and in this intermediate configuration, the cutting device is in the cutting configuration.
[0047] The locking system further includes: a second lever disposed within the base and rotatable relative to the base about a third lever axis, the second lever being configured to be driven by an actuation device to rotate about the third lever axis; and a second hook configured to move via the second lever and including a lower end, an upper end, and an elongated central portion, the lower end being attached to the second lever and rotatable relative to the second lever about a fourth lever axis parallel to the third lever axis, the elongated central portion connecting the lower end to the upper end. The central portion of the second hook extends through a second opening in the base and is guided by the second opening, enabling the second hook to: slide relative to the base along its central portion between a locked position and an unlocked position relative to the base, and simultaneously pivot relative to the base about a second pivot axis parallel to the fourth lever axis and passing through the second opening in the base between the locked and unlocked positions. The actuation device drives the second lever to rotate about the third lever axis in addition to driving the first lever to rotate about the first lever axis, thus operating the device between its locked and unlocked configurations. In the locking configuration of the appliance, the second hook is in its locked position and in its locked orientation, and the upper end of the second hook contacts the removable cover, thereby preventing the removal of the removable cover. In the unlocking configuration of the appliance, the second hook is in its unlocked position and in its unlocking orientation, and the upper end of the second hook is spaced apart from the removable cover, thereby allowing the removal of the removable cover.

[0059] Figure 11 yes Figure 9 and Figure 10The diagram shows a portion of the apparatus, illustrating the positions of the first lever and the first hook in both the unlocking and locking configurations of the apparatus. Detailed Implementation
[0060] In the following description, two axes are orthogonal if each is parallel to an axis that intersects at a right angle. In space, two orthogonal axes may or may not intersect. Two perpendicular axes are orthogonal and intersect.
[0061] Figures 1 to 8 A food preparation apparatus 10 according to a first embodiment of the present invention is illustrated schematically. In this example, apparatus 10 is a juicer.
[0062] As in Figure 1 and Figure 2 As particularly visible, the appliance 10 includes a base 12, a juice container 14 mounted on the base 12 and provided with a juice outlet 16, a tool 18, a removable cover 20 with a food inlet 22 arranged therein, and a reservoir or bin (not shown and generally arranged opposite to the juice outlet 16). The tool 18 is mounted on the base 12. More specifically, the rotating tool 18 is mounted on the juice container 14, which itself is mounted on the base 12. In this example, the tool 18 is a rotating tool that is rotatable relative to the base 12 about a main axis Z1, which is also a height axis, preferably vertical in the normal use configuration of the appliance 10. Here, the rotating tool 18 includes a bottom 18A forming a grinder and sidewalls 18B extending from the bottom, which constitute a sieve. The cover 20 is intended to be mounted on the rest of the appliance 10 to cover the rotating tool 18. In fact, the cover 20 is mounted on the juice container 14. In other words, the cover 20 is mounted on the base 12 via the juice container.
[0063] When food items are introduced into the appliance through the opening 22 of the cover 20 and the rotating tool 18 rotates, the food items come into contact with the grinder 18A, separating the juice from the solid parts (such as flesh). The juice passing through the sieve 18B flows into the juice tank 14, while the solid parts are guided by the sieve 18B to the storage container under the action of centrifugal force.
[0064] To drive tool 18, appliance 10 includes a motor 24 mounted on base 12. Here, motor 24 drives tool 18 by rotating it. For this purpose, motor 24 includes a motor shaft 26 extending along a main axis Z1. Motor shaft 26 is attached to rotating tool 18 such that the motor shaft can drive rotating tool to rotate about the main axis Z1. In practice, motor 24 and its motor shaft 26 are arranged inside base 12 so as not to be seen from the outside of appliance 10, and motor shaft 26 extends through juice container 14 so as to be attached to rotating tool 18. Preferably, motor 24 is powered by a power cable (not shown).
[0065] Appliance 10 includes a cutting device 28 operable between an energized configuration and a cutting configuration, in which the motor 24 is powered to drive the rotating tool 18, and in the cutting configuration, the motor 24 is not powered to prevent the rotating tool 18 from being driven. In other words, the cutting device 28 allows for the authorization or prohibition of motor 24 operation. In particular, the cutting device 28 prevents the motor 24 from starting when its operation would pose a danger to the user (e.g., when the cover 20 is not covering the rotating tool 18), as explained below. Therefore, the cutting device 28 has a safety function for appliance 10.
[0066] In this example, the cutting device 28 is an electrical contact comprising a body 28A and a probe 28B that can slide relative to the body 28A. The switching between the energized configuration and the cutting configuration of the cutting device is performed based on the position of the probe relative to the body.
[0067] The device 10 includes a braking system 30 capable of braking the rotation of the motor shaft 26 about a main axis Z1, which is also the height axis. Specifically, the braking system 30 includes a braking device 30A fixed to the motor shaft 26 and a braking member 30B translatable relative to the base 12, and therefore translatable relative to the braking device 30A along the main axis Z1.
[0068] The braking member 30B can translate along the main axis Z1 between a release position and a braking position. In the release position, the braking member 30B does not cooperate with the braking device 30A, so that the braking system 30 does not impede the rotation of the motor shaft 26 around the main axis Z1. In the braking position, the braking member 30B cooperates with the braking device 30A, so that the braking system 30 impedes the rotation of the motor shaft 26 around the main axis Z1. In other words, when the motor 24 is in operation and the braking member 30B is moved to the braking position, the braking system 30 brakes the rotation of the motor shaft 26, and then stops the motor shaft from rotating.
[0069] Advantageously, the braking member 30B is guided translatably relative to the base 12 along the main axis Z1 by a guide device (not shown). Preferably, the guide device also prevents the braking member 30B from rotating about the main axis Z1. Thus, the guide device facilitates the translation of the braking member 30B and prevents other movement of the braking member 30B. In addition, by guiding the braking member 30B, the guide device also makes it possible to guide the rod 44 to translate along the main axis Z1.
[0070] In this example, the braking device 30A is a brake disc rotatably fixed to the motor shaft 26, and the braking member 30B is a brake pad, preferably metallic, which contacts the brake disc 30A when in the braking position. The brake disc 30A and the brake pad 30B extend parallel to each other, preferably perpendicular to the main axis Z1. Advantageously, the brake disc 30A is equipped with a brake lining 30C extending from the brake disc 30A toward the brake pad 30B, thereby ensuring better braking between the brake disc and the brake pad.
[0071] Advantageously, the braking system 30 includes a reset member 30D that applies a force along the main axis Z1 to the braking member 30B, thereby bringing the braking member closer to the braking device 30A. In other words, the reset member 30D tends to return the braking member 30B to the braking position. In the example, the reset member 30D includes two compression springs extending along the main axis Z1 between the braking member 30B and the base 12.
[0072] Appliance 10 can be used Figure 5 and Figure 8 The locking configuration shown in the figure is the same as Figure 2 , Figure 3 and Figure 6 Operations between the unlocking configurations shown in the diagram.
[0073] In the locking configuration, the cover 20 is held on the rest of the appliance 10, in other words, the removal of the cover is prevented, allowing the appliance to operate safely without the risk of the user accessing the rotating tool 18 while it rotates around the main axis Z1. Additionally, in the locking configuration, the braking member 30B is in the released position, preventing the braking system 30 from braking the rotation of the motor shaft 26 around the main axis Z1, and the cutting device 28 is in the energized configuration, supplying power to the motor 24.
[0074] In the unlocked configuration, the cover 20 can be removed from the rest of the appliance 10, making access to the rotating tool 18 possible. Additionally, in the locked configuration, the braking member 30B is in the braking position, causing the braking system 30 to brake and prevent the rotation of the motor shaft 26 about the main axis Z1, and the cutting device 28 is in the cutting configuration, preventing the motor 24 from being powered. Through the cutting device 28 and the braking system 30, the appliance 10 is secured by two different devices when it is unlocked.
[0075] The appliance 10 includes a locking system 32 designed to securely hold the removable cover 20 to the remainder of the appliance 10 when the appliance is in a locked configuration, and not to prevent the removal of the cover when the appliance is in an unlocked configuration. The locking system 32 includes a first lever 34 and a first hook 36.
[0076] The operation of locking system 32 is in Figure 3 , Figure 4 and Figure 5 This is especially evident in the middle.
[0077] The first lever 34 is arranged within the base 12 and is rotatable relative to the base about a first lever axis X1 between a locked and unlocked position, the first lever axis being not parallel to the main axis Z1. In other words, the first lever 34 is pivotally mounted relative to the base 12 about the first lever axis X1. Here, the first lever axis X1 is orthogonal to the main axis Z1. Furthermore, the first lever axis X1 is fixed relative to the base 12. "Within the base" should be understood as the first lever 34 being located inside the base 12, that is, within the internal volume of the appliance 10 defined by the base 12. Figures 6 to 8 It is clearly visible in the middle. Therefore, the first lever 34 cannot be directly operated by the user of the appliance 10 from outside the base 12.
[0078] The first hook 36 includes a lower end 36A, an upper end 36B, and an elongated central portion 36C connecting the lower end 36A to the upper end 36B.
[0079] The lower end 36A is attached to the first lever 34 so that it can rotate relative to the first lever 34 about a second lever axis X2 parallel to the first lever axis X1. In other words, the first hook 36 is pivotable relative to the first lever 34 about the second lever axis X2. The lower end 36A is advantageously arranged inside the base 12. Thus, the first hook 36 moves via the first lever 34. More precisely, the lower end 36A is attached to the second lever axis X2 of the first lever, which causes the lower end to rotate about the first lever axis X1: as the first lever shifts between its locked and unlocked positions, the lower end 36A follows an arc about the first lever axis X1. Note that the second lever axis X2 is movable relative to the base 12.
[0080] In this example, the first lever 34 is formed by two identical and parallel plates connected by two shafts extending along the first lever axis X1 and the second lever axis X2, respectively. Other designs for the first lever are possible, such as an integral design.
[0081] The upper end 36B is designed to cooperate with the cover 20 when the appliance is in the locked configuration to retain the cover mounted on the rest of the appliance 10. More precisely, the upper end 36B is designed to cooperate mechanically with the cover 20, particularly through complementary shape cooperation, to retain the cover mounted on the rest of the appliance 10.
[0082] In this example, for this purpose, the upper end 36B has a hook shape that engages with the first lug 20A of the cover 20 when the appliance 10 is in the locked configuration. The upper end 36B is located on the outside of the base 12.
[0083] The central portion 36C connects the lower end 36A to the upper end 36B and extends through the first opening 12A of the base 12. In other words, the central portion 36C passes through the base 12, and the first opening 12A is a hole formed in the base 12. Advantageously, a seal is provided in the opening 12A to ensure the sealing of the base 12, through which the central portion 36C extends. The seal is, for example, an elastomeric seal.
[0084] Therefore, it should be understood that the lower end 36A of the first hook is disposed inside the base 12, while the upper end 36B is disposed outside the base 12. Thus, the first opening 12A of the base 12 passes through the base, connecting the interior of the base to the exterior. Furthermore, the hook 36, more specifically the central portion 36C, extends through the first opening 12A of the base 12 by passing through the base; that is, the hook 36 extends from the interior to the exterior of the base. In this way, the lower end 36A, like the first lever 34, is disposed inside the base 12, and is inaccessible to the user of the appliance 10 from the outside. Additionally, the seal provided in the opening 12A prevents liquids and solids from seeping into the interior of the base 12 from the outside through the first opening 12A, thereby extending the lifespan of the appliance 10, particularly by protecting the motor 24.
[0085] In this example, the elongated central portion 36C is cylindrical, making it straight and extending along the first hook axis Z2. In variations of the invention not shown, the central portion 36C has a different shape and / or is not straight. For example, the central portion 36C is curved or bent.
[0086] Since the central portion 36C extends through the first opening 12A of the base 12, the first opening of the base guides the central portion as the first hook 36 moves via the first lever 34. More specifically, the guidance of the central portion 36C by the first opening 12A of the base 12 allows the first hook 36 to slide relative to the base 12 along its central portion 36C between a locked position and an unlocked position, and simultaneously pivot relative to the base about a first pivot axis X3 parallel to the first lever axis X1 and the second lever axis X2 and passing through the first opening 12A of the base 12 between a locked position and an unlocked position. It should be understood that in this example, the sliding of the first hook 36 is performed along the first hook axis Z2. Note that the first pivot axis X3 is fixed relative to the base 12. Therefore, it should be understood that it is precisely because the central portion 36C extends through the base 12 by extending into the first opening 12A, i.e., from the inside of the base to the outside, that the central portion 36C is guided by the first opening 12A of the base, causing the first hook 36 to exhibit articulated sliding and pivoting movement.
[0087] It should be noted that the guidance of the first opening 12A to the central portion 36C forms a spherical / cylindrical mechanical connection between the first hook 36 and the base 12, commonly referred to as a ring-shaped linear connection. This guidance is advantageous due to the presence of a seal in the opening 12A.
[0088] In fact, the size of the first opening 12A is slightly larger than the size of the central portion 36C to allow the first hook 36 to pivot about the pivot axis X3. In other words, a functional gap is provided between the central portion 36C and the first opening 12A, thereby allowing the displacement of the central portion 36C to pivot about the pivot axis X3.
[0089] In fact, the first opening 12A guides the central portion 36C to prevent the first hook 36 from pivoting about an axis perpendicular to the first pivot axis X3, and also to prevent the first hook itself from rotating about the first hook axis Z2 in this example. However, these movements are prevented because the lower end 36A of the first hook 36 is attached to the first lever 34 and can only rotate and move relative to the first lever 34 about the second lever axis X2.
[0090] When the first lever 34 is in the locked position, it simultaneously reaches the locked position and locked orientation of the first hook 36; and when the first lever 34 is in the unlocked position, it simultaneously reaches the unlocked position and unlocked orientation of the first hook 36.
[0091] In the locking configuration of the device 10, the first lever 34 is in the locking position, and the first hook 36 is in the locked position and in the locking orientation. In the unlocking configuration of the device 10, the first lever 34 is in the unlocking position, and the first hook 36 is in the unlocking position and in the unlocking orientation.
[0092] When the first lever 34 operates between its locked and unlocked positions, the lower end 36A of the first hook 36 rotates about the axis X1 of the first lever. The first opening 12A of the combined base 12 guides the central portion 36C, causing the upper end 36B of the first hook 36 to move in an elliptical motion. This allows the upper end of the first hook to engage or disengage from the first lug 20A of the cover 20 effectively and reliably.
[0093] Advantageously, but optionally, the locking system 32 also includes a second lever 38 and a second hook 40 that are symmetrically similar to the first lever 34 and the first hook 36, respectively.
[0094] Therefore, the second lever 38 is rotatable relative to the base 12 about the third lever axis X4, and the second hook 40 includes a lower end 40A, an upper end 40B, and an elongated central portion 40C. The lower end is attached to the second lever 38 and is rotatable relative to the second lever about a fourth lever axis X5 parallel to the third lever axis X4. The upper end is designed to cooperate with the cover 20, which in this example has a hook shape cooperating with the second lug 20B of the cover 20. The elongated central portion connects the lower end 40A to the upper end 40B and extends along the second hook axis Z3 through the second opening 12B of the base 12. The second hook 40 is guided by the second opening 12B of the base 12 so that it can slide along its central portion 40C between a locked position and an unlocked position, and can pivot about a second pivot axis X6 parallel to the fourth lever axis X5 and the first pivot axis X3 and through the second opening of the base, similar to the first hook 36. Like the first hook 36, the upper end 40B of the second hook 40 is displaced in an elliptical manner. In this example, the third lever axis X4 is parallel to the first lever axis X1. In other words, in this example, the first lever 34 is parallel to the second lever 38. Advantageously, in this example, the first lever 34 and the second lever 38 extend in the same plane, which is parallel to and preferably passes through the main axis Z1. It should be noted that the fourth lever axis X5 is movable relative to the base 12. Like the first hook 36, the lower end 40A of the second hook is arranged inside the base 12, while the upper end 40B is arranged outside the base 12. Thus, the second opening 12B of the base 12 passes through the base, thereby connecting the interior of the base to the exterior of the base. Moreover, the second hook 40, more specifically the central portion 40C, extends through the second opening 12B of the base 12 by passing through the base, that is, the second hook 40 extends from the interior of the base to the exterior of the base. In this way, the lower end 40A, like the second lever 38, is arranged inside the base 12, and in particular, the user of the appliance 10 cannot reach it from the outside of the base. Additionally, the seal, preferably an elastomer, provided in the opening 12B and through which the central portion 40C extends, prevents liquids and solids from seeping into the interior of the base 12 from the outside through the second opening 12B, and also facilitates the guidance of the central portion 40C into the second opening 12B.
[0095] When the second lever 38 is in the locked position, it simultaneously reaches the locked position and locked orientation of the second hook 40, and when the second lever is in the unlocked position, it simultaneously reaches the unlocked position and unlocked orientation of the second hook.
[0096] In the locking configuration of the device 10, the second lever 38 is in the locking position, and the second hook 40 is in the locked position and locked. In the unlocking configuration of the device 10, the second lever 38 is in the unlocking position, and the second hook 40 is in the unlocking position and unlocking.
[0097] Therefore, the removable cover 20 is held on the rest of the appliance 10 by two hooks 36, 40 that cooperate with the two lugs 20A, 20B respectively.
[0098] In order to drive the first lever 34 and the second lever 38 to rotate between their locked and unlocked positions about the first lever axis X1 and the third lever axis X4 respectively, the locking system 32 includes an actuation device 42.
[0099] The operation of the actuator 42 is in Figure 6 , Figure 7 and Figure 8 This is especially evident in the middle.
[0100] In this example, the actuating device 42 includes a lever 44 that is rotatable relative to the base 12 about a lever axis Y1 between a locked and unlocked position. In this example, the lever axis Y1 is orthogonal to the main axis Z1, which improves the operation of the actuating device 42, but is not mandatory; the lever axis Y1 can also be tilted relative to the main axis Z1, i.e., not parallel to the main axis Z1. Furthermore, in this example, the lever axis Y1 is also orthogonal to the first lever axis X1 and the third lever axis X4, which improves the operation of the actuating device 42, but is not mandatory. Additionally, in this example, the lever axis Y1 is perpendicular to the main axis Z1, which improves the operation of the actuating device 42, but is not mandatory.
[0101] Here, the actuation device 42 includes a handle 46 attached to the lever 44 and rotatable relative to the base 12 about the lever axis Y1. The handle 46 is designed to be operated by a user, allowing the user to drive the lever 44 around the lever axis Y1 between its locked and unlocked positions. Advantageously, one hand is sufficient to operate on the handle 46. Additionally, the handle 46 allows the user sufficient leverage to effectively act on the lever 44 against the force applied by the reset member 30D.
[0102] The actuation device 42 also includes a first link 48, which is designed to drive the first lever 34 to rotate due to rotation of the rod 44. The first link 48 includes a first end 48A attached to the rod 44 so as to be rotatable relative to the rod about a first link axis Y2 parallel to the rod axis Y1. It should be noted that the first link axis Y2 is movable relative to the base 12.
[0103] The rod 44 and the first link 48 are arranged such that rotation of the rod 44 about the rod axis Y1 causes the first end 48A of the first link 48 to be displaced by moving in an arc about the rod axis Y1. In other words, when the rod 44 rotates about the rod axis Y1, the first end 48A of the first link 48 rotates about the rod.
[0104] In this example, to achieve the circular displacement, the first end 48A of the first link 48 is attached to the first connecting rod 50 of the actuator 42. This first connecting rod extends from the rod 44 perpendicular to the rod axis Y1 and is integral with the rod. The first end 48A of the first link 48 is pivotable relative to the first connecting rod 50 about the first connecting rod axis Y2. Therefore, the first link 48 is attached to the first connecting rod 50 at the first connecting rod axis Y2.
[0105] The first link 48 also includes a second end 48B, which is attached to the first lever 34 so as to be rotatable relative to the first lever about a second link axis X7 parallel to the first lever axis X1 and a third link axis Y3 parallel to the first link axis Y2. It should be noted that the third link axis Y3 is movable relative to the base 12.
[0106] Since the first link 48 is attached to the first lever 34 and the rod 44, the rotational movement of the rod 44 causes the first link to pivot in a plane perpendicular to the rod axis Y1, and causes the first link to translate, which is caused by the arc movement of its first end 48A.
[0107] In other words, when the first link 48 is displaced by the link 44, the first link drives the first lever 34 to rotate around the first lever axis X1 by applying the displacement of the first lever 34 at the second link axis X7.
[0108] Furthermore, the fact that the second end 48B of the first link 48 can rotate relative to the first lever 34 about the axis Y3 of the third link allows the first link to pivot in a plane perpendicular to the lever axis Y1 without causing movement of the first lever 34 in that plane. In fact, the mobility of the second end 48B of the first link 48 about the axis Y3 of the third link is achieved through a functional clearance between the second end 48B of the first link 48 and the first lever 34.
[0109] Advantageously, the actuation device 42 also includes a second link 52, which is designed to drive the second lever 38 to rotate due to the rotation of the lever 44, and functions the same as the first link 48. Therefore, the second link 52 includes a first end 52A attached to the lever 44 via a second connecting rod 54, thereby being rotatable relative to the second connecting rod 54 and relative to the lever 44 about the first link axis Y2. The second link 52 also includes a second end 52B attached to the second lever 38, so as to be rotatable relative to the second lever about a fourth link axis X8 parallel to the third lever axis X4 and a third link axis Y3 parallel to the first link axis Y2.
[0110] The actuation device 42 is configured such that rotation of the lever 44 about the lever axis Y1 between its locked and unlocked positions drives the first lever 34 to rotate about the first lever axis X1 via the first link 48, and drives the second lever 38 to rotate about the third lever axis X4 via the second link 52, and thus operates the device 10 between its locked and unlocked configurations, with the device in the locked configuration when the lever 44 is in the locked position and the device in the unlocked configuration when the lever is in the unlocked position.
[0111] Therefore, actuation of handle 46 causes displacement of first hook 36 and second hook 40, and thus allows device 10 to operate between its locked and unlocked configurations.
[0112] Therefore, the actuation device 42 is particularly advantageous for effectively converting the rotation of the handle 46 into the rotation of the two levers 34, 38 and thus into the movement of the two hooks 36, 40. Through the locking system 32 and the actuation device 42, the rotation of the handle 46 is sufficient to actuate the two hooks 36, 40 and thus operate the appliance 10 between its locked and unlocked configurations. Therefore, the appliance 10 is particularly easy for the user (including with one hand) to lock and unlock.
[0113] Particularly advantageously, the braking system 30 is operated by the locking system 32, and in particular by the actuating device 42. More precisely, the braking member 30B is translated relative to the base 12 along the main axis Z1 between its release position and braking position by the actuating device 42.
[0114] For this purpose, the braking member 30B is attached to the rod 44 so that it can rotate relative to the rod about the rod axis Y1 and be fixed relative to the rod along the main axis Z1. In other words, the braking member 30B is operated between its release position and braking position via the rod 44.
[0115] Additionally, lever 44 can translate relative to base 12 along main axis Z1 between a release position and a braking position. When lever 44 is in the release position, it reaches the release position of braking member 30B, and when lever 44 is in the braking position, it reaches the braking position of braking member 30B. Therefore, lever axis Y1 can move relative to base 12.
[0116] In practice, when the cover 20 is mounted on the rest of the appliance 10 and when the lever 44 is in its locked position, the lever 44 is in its released position. When the cover 20 is not mounted on the rest of the appliance 10 and / or when the lever 44 is in its unlocked position, the lever is in its braked position.
[0117] Advantageously, the rod 44 extends through a rectangular hole 12C in the base 12, which extends along the main axis Z1, allowing the rod 44 to pass through the base 12 without the base 12 preventing the rod 44 from translating along the main axis Z1.
[0118] Therefore, it should be understood that the lever 44 connects the interior of the base 12 to the exterior, allowing action from the exterior (in this example via the handle 46) on the levers 36, 38 arranged inside the base 12. This design is particularly advantageous for improving the durability of the appliance 10 while facilitating its use. In fact, only the upper ends 36B, 40B of the handle 46, hooks 36, 40, and a portion of the central portions 36C, 40C of the hooks 36, 40 are located outside the base 12, making these portions accessible only to the user of the appliance 10. Conversely, all other components of the locking system 32, particularly the actuation device 42, are located inside the base 12 and are therefore inaccessible from the exterior to the user of the appliance 10: thus, these other components are protected, thereby improving the lifespan of the appliance 10, and are invisible, thus improving the aesthetics of the appliance. In particular, the elliptical movement of the upper ends of the two hooks caused by a simple rotation of the handle 46 is aesthetically pleasing, while the entire actuation system and locking system allow the rotation of the handle to be converted into elliptical movement of these ends invisibly.
[0119] The lever 44 is fixed relative to the braking member 30B by translation. The force applied to the braking member 30B by the reset member 30D tends to return the lever to its braking position. In other words, the braking position of the lever 44 is a stationary position, or the position occupied by the lever when no other force is applied to the lever or the braking member 30B.
[0120] Therefore, when the cover 20 is not installed on the rest of the appliance 10, rotation of the lever 44 from its unlocked position to its locked position does not cause the lever to translate from its braked position to its released position. Instead, the force applied by the reset member 30D to the brake member 30B and the lever 44 causes the first hook 36 and the second hook 40 to slide beyond their locked positions. In fact, without the cover 20, nothing prevents the first hook 36 and the second hook 40 from sliding beyond their locked positions, and the force applied by the reset member 30D prevents the lever 44 from shifting from its braked position to its released position. Therefore, the rotation of the rod causes the first ends 48A and 52A of the first link 48 and the second link 52 to move in an arc around the rod axis Y1, thereby causing the first link 48 and the second link 52 to move away from the first opening 12A and the second opening 12B of the base 12. This causes the first lever 34 and the second lever 38 to rotate around the first lever axis X1 and the third lever axis X4 beyond their locking positions, and thus causes the first hook 36 and the second hook 40 to slide beyond their locking positions.
[0121] Conversely, when the cover 20 is installed on the rest of the appliance 10, rotation of the lever 44 from its unlocked position to its locked position causes the lever 44 to translate from its braked position to its released position against the force exerted by the reset member 30D on the brake member 30B and the lever 44. In effect, when the cover 20 is installed on the rest of the appliance 10, the first hook 36 and the second hook 40 contact the first lug 20A and the second lug 20B, preventing the first hook 36 and the second hook 40 from sliding beyond their locked positions. Therefore, the rotation of the rod causes the first ends 48A and 52A of the first link 48 and the second link 52 to move around the rod axis Y1 in an arc. However, because the first link 48 and the second link 52 cannot move away from the first opening 12A and the second opening 12B of the base 12 due to the contact of the first hook 36 and the second hook 40 against the first lug 20A and the second lug 20B, this movement of the first ends 48A and 52A of the first link 48 and the second link 52 causes the rod 44 to move from its braking position to its released position against the force applied by the reset member 30D. In other words, the contact of the first hook 36 and the second hook 40 against the first lug 20A and the second lug 20B makes it possible to overcome the force applied by the reset member 30D to the braking member 30B and the rod 44.
[0122] Therefore, the associated operation of the braking system 30 and the locking system 32, obtained by the actuator 42 operating the braking system 30, ensures that the braking member 30B can only reach its release position when the cover 20 is installed on the rest of the appliance 10 and when the first hook 36 and the second hook 40 are in their locked positions and in their locked orientation. In other words, the braking system 30 only allows the operation of the motor 24 when the cover 20 is installed on the rest of the appliance 10 and locked by the locking system 32, thereby preventing any start-up of the motor 24 when the user has access to the rotating tool 18.
[0123] It should also be noted that in the locking configuration of the device 10, the lever 44 is located along the main axis Z1 between the first end 48A and the second end 48B of the first link 48, and the lever 44 is located along the main axis Z1 between the first end 52A and the second end 52B of the second link 52. Conversely, in the unlocking configuration of the device 10, the first end 48A of the first link 48 is located along the main axis Z1 between the lever 44 and the second end 48B of the first link 48, and the first end 52A of the second link 52 is located along the main axis Z1 between the lever 44 and the second end 52B of the second link 52. These positions are obtained by an arc movement centered on the lever axis Y1, followed by the first end 48A of the first link 48 and the first end 52A of the second link 52. Therefore, when the appliance 10 is operated from its unlocked configuration to its locked configuration, along the main axis Z1, i.e., along the vertical axis, the first end 48A of the first link 48 and the first end 52A of the second link 52 move downwards, and the rod 44 moves upwards. Conversely, when the appliance 10 is operated from its locked configuration to its unlocked configuration, along the main axis Z1, i.e., along the vertical axis, the first end 48A of the first link 48 and the first end 52A of the second link 52 move upwards, and the rod 44 moves downwards.
[0124] In particular, these movements, obtained by the contact of the first hook 36 and the second hook 40 against the first lug 20A and the second lug 20B of the cover 20 and by the force applied to the brake member 30B by the reset member 30D, allow the first lever 34 and the second lever 38 to be operated simultaneously to lock and unlock the first hook 36 and the second hook 40, and to operate the brake system 30 to engage the brake member 30B or release it from the brake device 30A.
[0125] Particularly advantageously, the locking and unlocking orientations of lever 44 are selected such that, in the locking configuration of device 10, the first link axis Y2 lies on a first side of plane P passing through the link axis Y1 and the third link axis Y3, while in the unlocking configuration of device 10, the first link axis Y2 lies on a second side of plane P, opposite to the first side. Therefore, when the device operates between its unlocking and locking configurations, device 10 undergoes an aligned configuration, wherein the first link axis Y2 passes through plane P, i.e., wherein the first link axis Y2, the link axis Y1, and the third link axis Y3 are aligned.
[0126] Furthermore, in the alignment configuration of the device, the first link axis Y2, the rod axis Y1, and the third link axis Y3 are aligned along the main axis Z1, that is, they are aligned parallel to the direction in which the force applied to the braking member 30B by the reset member 30D tends to bring the braking member closer to the braking device 30A. Moreover, in the alignment configuration of the device, the force applied to the braking member 30B by the reset member 30D is the greatest. Therefore, in this example, the compression of the two compression springs is the greatest in the alignment configuration of the device. Therefore, the fact that the first link axis Y2, the rod axis Y1, and the third link axis Y3 are not aligned in the locking configuration of the device 10 is particularly advantageous, as this makes the locking configuration of the device 10 stable. In fact, it is necessary to apply a force against the reset force of the reset member 30D to move from the locking configuration of the device 10 to the alignment configuration of the device, thereby preventing the device from being accidentally unlocked. The actuation device 42 therefore acts as a mechanical switching device.
[0127] Advantageously, the cutting device 28 is mounted to operate between its energized and cutting configurations via the lever 44, such that the cutting device is in the energized configuration when the lever 44 is in the released position, and in the cutting configuration when the lever 44 is in the braking position. Therefore, the configuration of the cutting device 28 depends on the position of the lever 44 along the main axis Z1.
[0128] In this example, the body 28A is mounted on the braking member 30B to be translationally fixed relative to the braking member and movable relative to the base 12 along the main axis Z1, and the probe 28B is mounted on the base 12 to be fixed relative to the base. Therefore, when the braking member 30B is displaced by the rod 44 between its release position and braking position, the probe 28B moves relative to the body 28A, thereby switching the cutting device 28 between its energized configuration and its cutting configuration.
[0129] Advantageously, appliance 10 can also be used in Figure 4 and Figure 7 The illustrated operation takes place in an intermediate configuration between the locking and unlocking configurations, where the upper end 36B of the first hook 36 and the upper end 40B of the second hook 40 contact the cover 20 to prevent removal of the cover, and where the cutting device 28 is in the cutting configuration. Furthermore, in this intermediate configuration, the braking system 30 does not impede the rotation of the motor 24; that is, the braking member 30B is in the released position.
[0130] Therefore, when the appliance 10 moves from its locked configuration to its unlocked configuration, it passes through its intermediate configuration. In the locked configuration, the braking member 30B is in the released position, and the cutting device 28 is in the energized configuration, allowing the motor 24 to operate, and the motor shaft 26 and the rotating tool 18 to be driven to rotate about the main axis Z1. In the intermediate configuration of the appliance 10, the braking member 30B remains in the released position, but the cutting device 28 is in the cut-off configuration, so the motor 24 is not powered, but the motor shaft 26 and the rotating tool 18 can still rotate about the main axis Z1 because their rotation is not braked by the braking system 30. In the unlocked configuration of the appliance 10, the braking member 30B is in the braking position, and the cutting device 28 is in the cut-off configuration, so the motor 24 is not powered, and the rotation of the motor shaft 26 and the rotating tool 18 about the main axis Z1 is stopped by the braking system 30.
[0131] This opening sequence is particularly advantageous for extending the lifespan of appliance 10 because when the cutting device 30 is in the energized configuration, i.e., when the motor 24 is likely to operate, it prevents the braking system 30 from braking the motor shaft 26. In other words, the rotation of the motor shaft 26 can only be braked when the motor 24 stops, thus avoiding braking the motor while it is operating, which could damage the motor.
[0132] In addition, and as Figure 4 and Figure 5 as well as Figure 7 and Figure 8 As shown, once the device 10 is in the intermediate configuration, the first lever 34 and the second lever 38 reach their locked positions. This is particularly due to the arrangement of the rod 44, the first link 48 and the second link 52, and the first lever 34 and the second lever 38. Therefore, in the intermediate configuration, the first hook 36 and the second hook 40 are in their locked positions and locked orientations. In other words, the movement of the first hook 36 and the second hook 40 occurs between the unlocked configuration and the intermediate configuration of the device 10, and between the intermediate configuration and the locked configuration of the device 10, the first hook 36 and the second hook 40 remain in their locked positions and locked orientations. Moreover, it should be noted that, especially... Figures 3 to 5In this process, the compression of the reset member 30D (here, two springs 30D) mainly occurs between the intermediate and locking configurations of the appliance 10, particularly through the arrangement of the connecting rod 44, the braking member 30B, the first connecting rod 48 and the second connecting rod 52, and the first connecting rod 50 and the second connecting rod 54. However, it is precisely during the compression of the springs 30D that the force applied by the user on the handle 46 is at its maximum. Therefore, when the force applied to the handle is at its maximum, the first hook 36 and the second hook 40 do not move, resulting in the minimum force applied to the first lever 36 and the second lever 38, thereby reducing wear on the first lever and the second lever and thus extending the life of the appliance 10. Even when the first hook 36 and the second hook 40 do not move, the compression of the reset member 30D between the intermediate and locking configurations of the appliance 10 still causes the first hook 36 and the second hook 40 to compress against the removable cover 20 with a clamping force that ensures the secure closure of the appliance 10.
[0133] Furthermore, when the appliance 10 is operated from its locked configuration to its unlocked configuration, it should be noted that the motor 24 is electrically cut off by the cutting device 28 before the first hook 36 and the second hook 38 begin to shift from their locked and locked positions to their unlocked and unlocked positions, thus ensuring that the motor stops before the removable cover 20 is removed. Therefore, even if the user quickly manipulates the handle 46, the rotating tool 18 cannot be accessed before it is braked. Thus, the appliance 10 according to the invention is particularly safe to use, while being easy to lock and unlock via the locking system 32.
[0134] Figure 9 and Figure 10 A food preparation apparatus 10 according to a second embodiment of the present invention is shown. In the second embodiment, elements similar to those in the first embodiment have the same reference numerals and function in the same manner. The differences between the first and second embodiments will be described primarily below.
[0135] Additionally, if the component is mentioned in the description of the second embodiment but not in... Figure 9 and Figure 10 As shown in the diagram, this component corresponds to Figures 1 to 8 The same elements are shown in the first embodiment. The appliance 10 of the second embodiment is... Figure 9 The middle is shown as being in the unlocked configuration while Figure 10 It is shown as being in a locked configuration.
[0136] In fact, the food preparation apparatus 10 of the second embodiment has the same operation as that of the first embodiment, but is less expensive to manufacture than that of the first embodiment.
[0137] In particular, the locking system 32 of the food preparation utensil 10 of the second embodiment is particularly inexpensive to manufacture, while being reliable and robust.
[0138] Specifically, the first lever 34 includes a first piece 34A and a second piece 34B extending parallel to each other and parallel to the first lever axis X1. Furthermore, the first lever 34 is rotatable relative to the base 12 at the first lever axis X1 via a pivot piece 34C, which is mounted between the first piece 34A and the second piece 34B and extends through an opening 34D in the first and second pieces, which is transversely traversed by the first lever axis X1. The pivot piece 34C is secured to the base 12 using screws 34E, which hold the pivot piece 34C fixed relative to the base. This design allows for a reliable and robust connection of the first lever 34A to the base 12.
[0139] Furthermore, the lower end 36A of the first hook 36 is attached to the first lever 34 by a screw 36D extending along the axis X2 of the second lever, thereby enabling the first hook 36 to be effectively hinged relative to the first lever 34 at the axis X2 of the second lever.
[0140] Additionally, the first piece 34A and the second piece 34B have openings 34F that are traversed by the axis X7 of the second link. The second end 48B of the first link 48 is positioned between the first piece 34A and the second piece 34B of the first lever 34 and has a "T" shape, wherein two arms 48C extend along the axis X7 of the second link to extend through the openings 34F of the first and second pieces. The cooperation of the two arms 48C with the openings 34F allows the first link 48 to pivot relative to the first lever 34 about the axis X7 of the second link, while preventing further movement of the first link relative to the first lever.
[0141] The design of the second lever 38, the second hook 40, and the second link 52 is advantageously identical to that of the first lever 34 and the first link 48. Therefore, the second lever 38 includes a first piece 38A and a second piece 38B having openings 38D and 38F, and a pivot piece 38C fixed to the base 12 by screws 38E. The lower end 40A of the second hook 40 is attached to the second lever 38 by screws 40D extending along the axis X5 of the fourth lever. The second end 52B of the second link 52 has a "T" shape, with two arms 52C extending along the axis X8 of the fourth link.
[0142] Advantageously, the first pieces 34A and 38A, the second pieces 34B and 48B, the pivot pieces 34C and 38C, the first link 48 and the second link 52 are manufactured by laser cutting, which makes it possible to obtain parts with particularly low cost.
[0143] Advantageously, and as Figure 9 and Figure 10As can be seen, openings 34D, 34F, 38D, and 38F are not circular, but rather have the shape of two sectors or two circular disk sectors connected by their vertices. Therefore, openings 34D, 34F, 38D, and 38F respectively restrict the angular displacement of pivot plate 34C, the two arms 48C of the first link 48, and the two arms 52C of the pivot plate 34C and the second link 52.
[0144] In the second embodiment, the braking member 30B includes a brake pad 31A extending parallel to the braking device 30A and perpendicular to the main axis Z1, two sidewalls 31B extending perpendicularly from the brake pad 31A and thus reinforcing the braking member 30B, and two edges 31C extending from the brake pad 31A perpendicular to the rod axis Y1, through which the rod 44 traverses. Therefore, the two edges 31C ensure attachment between the braking member 30B and the rod 44, thereby preventing translation of the braking member relative to the rod but allowing rotation of the braking member relative to the rod about the rod axis Y1. The braking member 30B is advantageously made from a flat sheet of material that has been cut and then bent, allowing for a particularly low-cost component while ensuring a reliable connection between the braking member 30B and the rod 44.
[0145] In the second embodiment, the first connecting rod 50, which attaches the first end 48A of the first connecting rod 48 to the rod 44, is not integral with the rod 44, but is fixed to the rod using a fixing member 50A, preferably a screw. Furthermore, the first connecting rod 50 is connected to the first end 48A of the first connecting rod 48 via a fixing member 50B (here, a shoulder screw), thus allowing the first end 48A to be fixed to the connecting rod 50 without preventing the first end 48A from rotating relative to the connecting rod 50 about the axis Y2 of the first connecting rod. The second connecting rod 54 is designed similarly, being fixed to the rod 44 using a fixing member 54A and to the second connecting rod using a fixing member 54B. This design makes the production cost of the actuator 42 particularly low because the cost of manufacturing the connecting rods 50, 54 and their attachment to the connecting rods 48, 52 and the rod 44 is lower.
[0146] In the second embodiment, the reset member 30D includes four compression springs extending along the main axis Z1 between the braking member 30B and the base 12. Figure 9 and Figure 10 Only two compression springs are visible in the image. Using four compression springs improves the translational guidance of the braking member 30B along the main axis Z1 compared to the first embodiment which uses two compression springs. Advantageously, the brake pad 31A is substantially rectangular, and the four compression springs are arranged at the four corners of the brake pad 31A.
[0147] Advantageously, in the second embodiment, the braking member 30B is guided by a guide device 60 to translate relative to the base 12 along the main axis Z1. Preferably, the guide device 60 also prevents the braking member 30B from rotating about the main axis Z1. Thus, the guide device 60 facilitates the translation of the braking member 30B and prevents other movements of the braking member 30B. In addition, by guiding the braking member 30B, the guide device also makes it possible to guide the rod 44 to translate along the main axis Z1.
[0148] In the example of the second embodiment, the guiding device 60 includes two guiding axes 60, which are fixed to the base 12 and extend parallel to the main axis Z1 through the brake member 30B, more specifically through the two openings of the brake member 30B. Therefore, the two guiding axes 60 do not impede the translation of the brake member 30B along the main axis Z1, but rather prevent the brake member 30B from translating perpendicularly to the main axis Z1. Furthermore, the two guiding axes 60 are arranged on both sides of the motor shaft 26 in a plane perpendicular to the main axis Z1, thus effectively preventing the brake member 30B from rotating about the main axis Z1. Therefore, when the brake member 30B is in the braking position, rotation of the braking device 30A does not easily cause the brake member 30B to rotate about the main axis Z1, and braking of the braking device 30A and therefore the motor shaft 26 is effective.
[0149] Now for reference Figure 11 describe Figure 9 and Figure 10 The second embodiment of the device 10 shown exhibits certain geometric and kinematic characteristics. In fact, combined with… Figure 11 The described geometric and kinematic properties also apply to Figures 1 to 8 The appliance 10 of the first embodiment.
[0150] In the following text, reference is made only to the geometry and kinematics of the first lever 34 and the first hook 36 of the device 10 of the second embodiment, but the description also applies to the second lever 38 and the second hook 40.
[0151] In particular, Figure 11 In the diagram, the base 12, the juice container 14, and the removable lid 20 are schematically represented by their housings. In particular, the first lug 20A of the lid 20, the first opening 12A of the base 12, and the first pivot axis X3 are shown.
[0152] Additionally, the first lever 34 and the first hook 36 are schematically shown.
[0153] More precisely, the first lever 34 is illustrated only by its outline between the first lever axis X1 and the second lever axis X2. The outline of the first lever 34 is illustrated by a solid line in its locked position and a dashed line in its unlocked position, indicating its locked and unlocked positions. The second lever axis X2 is marked as X2A in the locked position and X2B in the unlocked position of the first lever 34.
[0154] Similarly, the first hook 36 is illustrated only by its outline, which is represented by a solid line in its locked orientation and locked position, and by a dashed line in its unlocked orientation and unlocked position.
[0155] Therefore, it should be noted that, as mentioned above, the upper end 36B of the first hook 36 follows an elliptical trajectory, i.e., an elliptical arc, between the unlocking and locking configurations of the device 10. Figure 11 Highlighted in the middle.
[0156] Figure 11 The image also shows a first pivot axis X3 fixed relative to the base 12.
[0157] Preferably, the first lever axis X1 is arranged at a distance D1 between 60 mm and 90 mm from the main axis Z1 (i.e., from the motor shaft 26), measured perpendicular to the main axis Z1, for example, equal to 75 mm.
[0158] Preferably, the length L1 of the first lever 34, measured in a plane perpendicular to the first lever axis X1 between the first lever axis X1 and the second lever axis X2, is between 18 mm and 29 mm, for example, equal to 23.5 mm.
[0159] Preferably, the angular displacement θ1 of the first lever 34 about the first lever axis X1 between its locked position and its unlocked position is greater than 30°, preferably still between 30° and 60°, preferably still between 40° and 50°, for example equal to 45.5°.
[0160] Preferably, the distance D2 measured between the first lever axis X1 and the first pivot axis X3 in a plane perpendicular to the first lever axis X1 is between 45 mm and 78 mm, and preferably still between 56 mm and 67 mm, for example equal to 61.4 mm.
[0161] Advantageously, the ratio between distance D2 and length L1 is between 1.5 and 4.5, preferably still between 2 and 3, for example equal to 2.6. This ratio allows for the sliding and pivoting of the first hook f36 by rotation of the first lever 34 about the first lever axis X1, thereby allowing both effective retention of the cover 20 in the locking configuration of the appliance 10 and sufficient distance between the first hook and the cover in the unlocking configuration of the appliance, thus allowing for easy removal of the cover.
[0162] Additionally, the distance D3 measured along the main axis Z1 between the first lever axis X1 and the first pivot axis X3 is between 38.5 mm and 66.7 mm, preferably still between 45 mm and 59 mm, for example equal to 52.5 mm.
[0163] Furthermore, the distance D4 measured between the first pivot axis X3, which is perpendicular to the main axis Z1, and the main axis Z1 is between 80 mm and 130 mm, preferably between 95 mm and 117 mm, for example equal to 106.5 mm.
[0164] Preferably, when the first lever 34 is in its locked position, the angle θ2 formed between the lower end 36A of the first hook 36 and the first lever 34, more specifically between the lower end 36A of the first hook 36 and the axis connecting the first lever axis X1 to the second lever axis X2, is between 75° and 115°, preferably between 85° and 95°, for example equal to 90°.
[0165] Preferably, the length L3 of the first hook 36, measured in a plane perpendicular to the first pivot axis X3, between its lower end 36A and its upper end 36B, and more precisely parallel to the central portion 36C of the first hook 36, is between 150 mm and 215 mm, preferably between 175 mm and 190 mm, for example equal to 182.8 mm.
[0166] Preferably, when the first lever 34 is in its locked position and when the first hook 36 is in its locked position and in its locked position, the internal length L2 of the first hook 36, measured in a plane perpendicular to the first pivot axis X3 between its lower end 36A and the first pivot axis X3, and more precisely parallel to the central portion 36C of the first hook 36, is between 50 mm and 65 mm, preferably between 55 mm and 60 mm, for example equal to 56.7 mm.
[0167] Preferably, when the first lever 34 is in its locked position and when the first hook 36 is in its locked position and in its locked position, the angle θ3 between the center portion 36C of the first hook 36 and the main axis Z1, measured in a plane perpendicular to the first pivot axis X3, is less than 13°, preferably still between 5° and 13°, preferably still between 7° and 11°, for example equal to 9°.
[0168] Preferably, when the first lever 34 is in its unlocked position and when the first hook 36 is in its unlocked position, the internal length L4 of the first hook 36, measured in a plane perpendicular to the first pivot axis X3 between its lower end 36A and the first pivot axis X3, and more precisely parallel to the central portion 36C of the first hook 36, is between 34 mm and 47 mm, preferably between 38 mm and 43 mm, for example equal to 40.5 mm.
[0169] Therefore, the linear displacement of the first hook 36 along its central portion 36C between its locked position and its unlocked position is greater than or equal to 10 mm, preferably greater than or equal to 15 mm, and in this example equal to 16.2 mm. In other words, the length by which the first hook 36 slides in the first opening 12A is preferably greater than or equal to 10 mm, preferably still greater than or equal to 15 mm, and in this example equal to 16.2 mm.
[0170] Preferably, when the first lever 34 is in its unlocked position and when the first hook 36 is in its unlocked position and in its unlocked position, the angle θ4 between the center portion 36C of the first hook 36 and the main axis Z1, measured in a plane perpendicular to the first pivot axis X3, is greater than or equal to 5°, preferably still between 5° and 25°, preferably still greater than or equal to 10°, preferably still between 10° and 23°, for example equal to 19°.
[0171] Therefore, the angular displacement of the first hook 36 about the first pivot axis X3 between its locked position and its unlocked position (i.e., the difference between the locked position and the unlocked position of the first hook) is greater than or equal to 5°, preferably greater than or equal to 10°, and in this example equal to 10°.
[0172] By means of the angular displacement of the first hook 36 between its locked and unlocked positions, and to a lesser extent by means of the linear displacement of the first hook between its locked and unlocked positions, the first hook 36 is sufficiently moved away from the removable cover 20 to allow the user to easily remove the cover from the rest of the appliance 10 when the appliance is in the unlocked configuration.
[0173] Specifically, the distance D5, measured perpendicularly to the main axis Z1, between the upper end 36B of the first hook 36 in its unlocked position and in its locked position, is advantageously between 10 mm and 40 mm, preferably between 20 mm and 30 mm, and in this example equals 26.4 mm. Therefore, the upper end 36B of the first hook 36 is sufficiently far from the rest of the appliance 10 perpendicularly to the main axis Z1 so as not to hinder the removal of the cover 20 from the rest of the appliance during translational movement along the main axis Z1.
[0174] The aforementioned specific dimensions allow for efficient movement of the first hook 36 to hold the cover 20 in the locked configuration of the appliance 10 without hindering removal of the cover in the unlocked configuration of the appliance 10.
[0175] In a variation of the invention not shown, the upper ends 36B, 40B of the first hook 36 and the second hook 40 cooperate with the cover 20 in a manner different from that of the first lug 20A and the second lug 20B. For example, the cover 20 has two recesses or notches in which the lugs of the upper ends 36B, 40B are received when the appliance is in a locked configuration. The invention is not limited to these examples.
[0176] In an unshown variant of the invention, the cover 20 does not include a second lug, the locking system 32 does not include a second lever or a second hook, and the actuation device 42 does not include a second link. In this variant, the cover 20 is held locked only by the first hook 36, or by another locking device (e.g., a hook that holds the cover 20 fixed relative to the juice bowl 14).
[0177] In an unshown variation of the invention, the lever 44 extends along a lever axis parallel to the first lever axis X1. In this variation, the second link axis X7 and the third link axis Y3 coincide. This variation is particularly advantageous for simplifying the design of the appliance when the appliance 10 comprises only a lever and a hook.
[0178] In an unshown variant of the invention, the locking system includes different actuating devices to operate the first lever 34 and the second lever 38. For example, the first lever 34 and the second lever 38 are directly operated by a handle that does not operate the braking system 30. In this variant, the braking system 30 can be operated independently of the locking system 32.
[0179] In an unshown variant of the invention, the cooking preparation appliance 10 is a device of a type other than a juicer, such as a citrus press, blender, chopper, ice crusher, cheese shredder, vegetable cutter, or multi-functional robot.
[0180] In an unshown variant of the invention, tool 18 is not a rotary tool, but rather a tool that moves, for example, by translation relative to base 12, or by movement relative to base combining one or more translations and / or one or more rotations relative to base. For example, the tool moves by translation along a main axis Z1, like a press, such as a citrus press. In this variant, motor 24 drives tool 18 via a transmission adapted to convert the rotational movement of motor 24 into movement suitable for tool 18.
[0181] In a variant of the invention not shown, the motor 24 does not extend along a vertical axis. In other words, the main axis Z1 corresponding to the axis of rotation of the motor 24 is not necessarily vertical; however, this orientation is preferred when the tool 18 is a rotary tool that rotates about a vertical axis to simplify the design of the appliance 10. It should be noted that in relation to... Figures 1 to 11 In the description of the illustrated embodiments, references are vaguely made to the main axis Z1 corresponding to the rotation axis of the motor 24 and the height axis, because in these embodiments, the main axis Z1 is vertical, i.e., it corresponds to the height axis. Therefore, it should be understood that in variations where the main axis Z1 is not vertical, certain characteristics described above in conjunction with the main axis Z1 are then understood in conjunction with the height axis (which is vertical in this case). For example, for the operation of the actuator 42, the orthogonality of the rod axis Y1, the first link axis Y2, and the third link axis Y3 to the height axis is advantageous, but when the main axis Z1 is not the height axis, the orthogonality of these axes to the main axis Z1 does not provide any particular advantage. Instead, it is advantageous for the braking member 30B to translate relative to the base 12 along the main axis Z1 corresponding to the rotation axis of the motor 24, but the fact that the braking member 30B translates relative to the height axis does not produce any particular advantage. However, it is particularly advantageous that the axis of rotation of the motor 24 is a height axis, especially a vertical one, because this facilitates the design of the appliance 10 by simplifying and optimizing the interaction between the braking system 30 and the actuation device 42.
[0182] Any feature described for one of the foregoing embodiments or variations may be implemented for other embodiments and variations, provided that it is technically feasible.

When the removable cover (20) is installed on the rest of the cooking preparation appliance (10) and when the lever (44) is in its locked position, the lever (44) is released. The cooking appliance (10) further includes a braking system (30) capable of braking the rotation of the motor (24) around the main axis (Z1). The braking system (30) includes: Braking device (30A), the braking device being rotatably integrated with the motor (24), and A braking member (30B) is attached to the rod (44) to allow rotational movement relative to the rod (44) about the rod axis (Y1) and translational fixation relative to the rod (44) along the main axis (Z1).
