Description

Technical Field

[0001] This invention relates to a container for containing, keeping warm, and / or serving food, wherein the container includes a base capable of being closed by means of a lid. According to one aspect, a brake is provided that decelerates (brakes) the closing movement of the lid. According to another aspect, a connecting module for connecting the lid to the base is provided, wherein the connecting module is detachably connected to the lid and the base. Background Technology

[0002] Containers used for holding, storing, and serving food, such as those used in buffets to keep food warm in a water bath. Containers typically comprise a dish-shaped base (trough-shaped base) that can be closed by a lid. Containers are known in various embodiments, for example, to include flat or curved lids that can be opened or closed as needed to store and display the food stored in the container in a fresh and attractive manner for as long as possible. These containers are also known in the food service industry as "hot pots".

[0003] One problem with these devices is the operation of the lid. A removable lid, which rests only on the base to close it and is not hinged to it, requires additional space to be placed, which must remain unobstructed. A lid that pivots about a horizontal axis and is hinged to the base should also be fully pivotable rearward, for example, to allow removal of the water bath container. In this process, there is a risk that the waiter might lose control of the relatively heavy lid, causing it to flip backward and downward, potentially moving containers on the table, causing the water used to keep food warm to slosh, and spilling food. When the lid is closed, the waiter must reach far back and downward to grasp it. Therefore, improvements to the lid's closing mechanism are needed.

[0004] Sometimes, it is desirable to be able to completely detach a lid that is hinged to the base. For example, one might want to clean the lid separately from the base in a dishwasher. While some previously known lids can be removed, these lids contain mechanical parts that are unsuitable or only conditionally suitable for use in a dishwasher. Other lids can only be removed from the base using tools designed for this purpose. Finding a practical solution for removable lids would be beneficial. Summary of the Invention

[0005] The purpose of this invention is to design a container for containing, keeping warm and / or supplying food, which can at least partially solve the above-mentioned problems.

[0006] This objective is achieved by a container having the features of the main claim. Other embodiments of the invention are defined by the subject matter of the dependent claims and the following description.

[0007] According to a first aspect, a container is provided, particularly for containing, keeping warm, and / or serving food. The container includes:

[0008] -Matrix;

[0009] - A cover for closing the base, which can pivot between a closed position and an open position by means of a rotary joint; and

[0010] - At least one brake for braking (decelerating) the pivoting movement of the cover and / or for holding the cover in a position between a closed position and an open position.

[0011] The brake includes a flywheel and is configured to brake (decelerate) the pivoting motion of the cover in the closing direction, but not to brake (decelerate) the pivoting motion of the cover in the opening direction.

[0012] The flywheel typically defines a blocking direction and a freewheeling direction. The blocking direction preferably corresponds to the closing direction of the cover, and / or the freewheeling direction corresponds to the opening direction of the cover. In other words, the flywheel is coupled to the pivoting motion of the cover, causing the brake to brake (decelerate) or hold the cover in the closing direction rather than the opening direction.

[0013] The brake can be specifically designed to hold the lid in multiple positions, preferably in an infinitely adjustable (steplessly) manner between a closed and an open position. The open position represents the position where the lid is opened to its maximum extent and therefore has its maximum opening angle. The maximum opening angle can be determined by at least one stop. In this case, the pivoting movement of the lid is thus limited by the stop. In the closed position, the lid completely covers the substrate. Due to the brake, it is generally possible for the lid to actually remain in any position between the closed and open positions. Therefore, the user only needs to move the lid to a position where food can access it, and the lid automatically holds in that position after being released due to the braking force of the brake. This also means that a small amount of manual force is required to overcome the braking force of the brake when closing the lid. This required manual force is typically greatest in the open vertical position of the lid, for example, at approximately 90°, and decreases steadily during closing due to the increased lever arm. Typically, during the intended use of the container, the lid is oriented substantially horizontally in the closed position, i.e., perpendicular to gravity.

[0014] Alternatively, the brake is a mechanical friction brake. In other words, the braking force is generated by friction between a stationary body and a moving body. Such brakes are typically robust and have a relatively simple design. In one embodiment, the brake includes at least one brake pad and a brake disc. It may be provided that the brake disc is arranged stationary relative to the base. The brake pad may move relative to the base during the movement of the cover. Alternatively, the brake pad may be arranged stationary (fixed) relative to the base. In this case, the brake disc moves relative to the base during the movement of the cover.

[0015] In some embodiments, the rotary joint (swivel joint) includes a rotatable shaft coupled to a flywheel and connected to a cover. The shaft typically rotates synchronously with the pivoting movement of the cover; that is, when the cover pivots, both elements rotate by the same angle. Optionally, the brake is configured such that the brake pad and brake disc are stationary (fixed) relative to each other in the direction of the shaft's inertial motion, and that the relative movement of the brake pad and brake disc in the blocking direction of the shaft is braked (decelerated). Furthermore, a spring element may be provided, wherein the spring element is configured to push the brake pad and brake disc together in the axial direction.

[0016] The shaft may be surrounded by a bearing bushing. The shaft may be arranged or mounted within an internal space defined by the bearing bushing. The bearing bushing may be connected to at least one cover that at least partially closes the internal space defined by the bearing bushing. A brake pad may be non-rotatably connected to the bearing bushing, for example, by form-fitting.

[0017] For example, a flywheel can be mounted on a shaft. The flywheel is typically configured as a one-way roller clutch. Optionally, the flywheel is arranged radially between the bearing bushing and the shaft. In one embodiment, at least one rolling bearing is arranged radially between the bearing bushing and the shaft, for example, two rolling bearings, or even more than two rolling bearings if desired. Alternatively or as a supplement, at least one rolling bearing can be integrated into the flywheel. At least one sealing element can be provided, configured to seal the flywheel and / or at least one rolling bearing against water and moisture. Furthermore, a brake can be arranged in a housing, which may sometimes comprise two partial housings. For example, the brake can be arranged in or at a connecting module that connects the cover to the base. In particular, the connecting module further described below is a suitable connecting module.

[0018] The brake disc may surround the shaft, flywheel, and / or bearing bushing in the radial direction. Optionally, a sliding bearing is arranged radially between the bearing bushing and the brake disc, which allows the bearing bushing to rotate relative to the brake disc, preferably with low friction.

[0019] In summary, the above-described type of brake enables low-noise braking and a long service life. Furthermore, the brake allows for infinitely adjustable cover positioning (stepless cover positioning). Additionally, the brake is characterized by a small number of parts and easy assembly.

[0020] According to the second aspect, another container specifically designed for containing, keeping warm, and / or serving food is described. This container includes:

[0021] -Matrix;

[0022] - A cover for closing the base, which can pivot between a closed position and an open position;

[0023] as well as

[0024] - Connection module, used to connect the cover to the base.

[0025] The connecting module includes a first connecting element detachably connected to the cover. Additionally, the connecting module includes a second connecting element detachably connected to the base. Furthermore, the connecting module includes at least one component for enabling pivotal movement of the cover.

[0026] The term "detachable connection" should be specifically understood to mean that the connection can be disassembled non-destructively and without tools. In this way, the connection module enables a modular connection between the cover and the base. Specifically, the connection module can be detached from both the base and the cover. Due to the modularity of the connection, the base, cover, and connection module can be replaced, repaired, and / or cleaned individually. For example, the base and cover can be cleaned separately from the connection module. This can be particularly useful when the connection module or its components, such as the aforementioned components used to enable the pivoting movement of the cover, are sensitive to water, moisture, and / or cleaning agents.

[0027] The aforementioned components may include, or be brakes, for braking (decelerating) the pivoting movement of the cover and / or for holding the cover between a closed position and an open position. The brakes may be constructed similarly to those described with respect to the first aspect. Alternatively or additionally, the aforementioned components may include, or may be, motor elements for moving the cover between the closed and open positions. The connection module may include a housing in which the component is disposed.

[0028] Optionally, the first connecting element includes a first form-fitting element connectable to a first mating member, which is attached to the cover to form a first form-fit. For example, the first form-fitting element is configured as a protrusion, while the first mating member includes a first receptacle having a complementary shape.

[0029] In one improved embodiment, a first spring-loaded pressure member (spring plunger) is provided, which engages in a first locking recess when a first form-fit is present. The first spring-loaded pressure member (spring plunger) helps to secure the first form-fit. The first spring-loaded pressure member is, for example, mounted in a first form-fit element. Furthermore, the first locking recess can be formed in a first mating member. The first locking recess is typically formed in the inner wall of the mating member. Alternatively, the first spring-loaded pressure member can also be mounted in the mating member. In this case, the first locking recess is formed in the first form-fit element.

[0030] The first connector can preferably be released at an opening angle of at least 45° of the cap without the base needing to be manually held in place. The spring force or holding force of the first spring-loaded pressure member and / or the geometry of the first form-fit connector can be designed such that the manual force required to release the first connector is generally minimal when the opening angle of the cap is between 80° and 100°, preferably between 85° and 95°, and particularly around 90°. For example, at a certain opening angle of the cap, particularly 90°, the longitudinal axis (or longitudinal direction) of the first form-fit element and the longitudinal axis (or longitudinal direction) of the first mating member extend parallel to gravity, such that the form-locking connection between the cap and the first connector can be released by lifting the cap in the open position.

[0031] Optionally, the second connecting element includes a second form-fitting element that can be connected to a second mating member, which is attached to the base to form a second form-fit. Typically, a second spring-loaded pressure member (spring plunger) is provided, which latches in a second locking recess when the second form-fit is present. The second spring-loaded pressure member (spring plunger) helps to secure the second form-fit.

[0032] For example, a second spring-loaded pressure member can be installed in the second form-fitting element. Furthermore, a second locking recess can be formed in the second mating member. The second locking recess is typically formed in the inner wall of the second mating member. Alternatively, a second spring-loaded pressure member can also be installed in the second mating member. In this case, the second locking recess is formed in the second form-fitting element.

[0033] In some embodiments, a second form-fitting element engages in a second receptacle formed in a mating member. The second form-fitting element is configured, for example, as a stud, while the second receptacle has a complementary shape. A second locking recess is typically formed in the inner wall of the second receptacle. Furthermore, a second spring-loaded pressure member may be mounted in the second form-fitting element. The longitudinal axis of the second spring-loaded pressure member may extend at an angle, preferably perpendicular, to the longitudinal axis of the second form-fitting element. The second locking recess may be configured as a through-hole, allowing the second spring-loaded pressure member to be detached from the outside, preferably by pushing it with a finger.

[0034] To release the second form-fit element, a third spring-loaded pressure member (spring plunger) can be provided, which is preloaded when the second spring-loaded pressure member is locked. The third spring-loaded pressure member (spring plunger) can be configured to at least partially push the second form-fit element out of the receptacle when the second pressure member is released from the second locking recess. The longitudinal axis of the third spring-loaded pressure member can be oriented parallel to and / or perpendicular to the longitudinal axis of the second form-fit element.

[0035] In some embodiments, a third spring-loaded pressure member is mounted in the second form-fitting element. When the second spring-loaded pressure member is locked, the third spring-loaded pressure member can abut against the inner wall of the receiver. Optionally, a third recess may be formed in the inner wall of the receiver, and the third pressure member engages in the third recess.

[0036] At least one of the aforementioned spring-loaded pressure members may include a sleeve and a spring element disposed within the sleeve, as well as a pressure member, such as a ball or pin, partially disposed within and partially protruding from the sleeve. The spring element is designed to apply a spring force to the pressure member, thereby preloading the pressure member.

[0037] Typically, the first connecting element and the second connecting element are connected to each other via a central member, wherein the components for realizing the pivotal movement of the cover are optionally attached to or mounted in the central member.

[0038] Sometimes, the container may include two connecting modules of the type described above. It can be provided that the longitudinal directions of the first shape-fitting elements extend parallel to each other and point in the same direction. The first shape-fitting element can also be released simultaneously by pulling the lid. Alternatively, it can be provided that the longitudinal directions of the second shape-fitting elements extend parallel to each other, but are oriented in opposite directions (anti-parallel). As a result, the second shape-fitting element cannot be released while the lid is still attached to the connecting module. Instead, the second shape-fitting element (i.e., the connection between the connecting module and the base) can only be released when the lid has been detached from the connecting module. This reduces the likelihood that the lid and connecting module will be cleaned together.

[0039] The substrate is typically shaped like a groove (disc). The substrate generally includes a bottom surface, a front wall, a rear wall, and two side walls, wherein the connecting module is preferably attached to the rear wall of the substrate, and particularly to the upper side of the rear wall. The rear wall may extend laterally from a first end section to a second end section, wherein each end section is connected to a side wall. The connecting module is preferably attached to the end section of the rear wall. This outwardly positioned connection of the connecting module is due to the utilization of the flexural stiffness of the side walls and / or corner radii. This prevents or reduces bending of the rear wall when the cover is opened or closed. Consequently, additional rear wall reinforcement plates can be omitted. Therefore, the bottom surface, front wall, rear wall, side walls, and / or substrate can be designed as a single unit. In addition to reducing manufacturing costs, this ensures an attractive appearance and / or reduced cleaning effort. Sometimes, at least one bearing seat is provided in the substrate for connection to a second connecting element.

[0040] The connection between the connecting module and the base can be designed so that the connecting module can be easily and tool-free removed, and therefore can be replaced. In addition to mobility and the associated ease of operation and maintenance, it also creates the option to replace or upgrade the component at a later time to affect the pivoting movement of the cover with another part, without having to redesign the base and / or the cover.

[0041] Thus, modularity can also provide different versions of the connection modules that are interchangeable with each other (e.g., with / without motor components and / or with / without brakes). In this regard, the invention can also provide a system comprising a base, a cover, and at least two connection modules, wherein each connection module preferably includes different components for influencing the pivotal movement of the cover.

[0042] The features of the container according to the first aspect can be combined with the features of the container according to the second aspect, and vice versa; that is, the features of the container according to the second aspect can be combined with the features of the container according to the first aspect. In a preferred embodiment, the container according to the first aspect and the container according to the second aspect have the same features.

[0043] In a further specific embodiment, the container according to one of the above aspects may be part of a system including additional components. Furthermore, a water bath container may be provided, which is contained within a substrate. The space formed between the substrate and the water bath container may be filled with water. A heating device may be provided to heat the water and / or maintain its temperature. The container may, for example, be arranged on a support with a heating device underneath it, wherein a fuel tank or an electric heating element may be used as the heating device, for example.

[0058] In the following description and figures, repeated and functionally equivalent features are indicated by the same reference numerals. For clarity, some reference numerals are not provided in each example, even though related elements may be present in the relevant examples.

[0059] Figures 1-5 Different views of a container 1 for containing, keeping warm, and / or serving food are shown. Container 1 includes a trough-shaped (basin-shaped) base 2 and a lid 10 for closing the base 2, the lid being pivotable about a pivot axis 40 between a closed position and an open position, with container 1 shown in the closed state. Container 1 may optionally be arranged on a support that includes a heating device below it, wherein a fuel canister or electric heating element is typically used as the heating device. The base 2 typically forms a seat for a similarly trough-shaped water bath container (not shown) in which food can be kept warm, wherein water is typically present between the base 2 and the water bath container when container 1 is in use, such that the water bath container is situated in a water bath. The water is then heated by the aforementioned heating device. This container 1 is also known as a "warmer" and is used in buffets, for example, to keep food warm and to display it. Container 1 is known in various embodiments, including, for example, a flat or curved lid 10 that can be opened or closed as needed. In order to allow the food to be seen even when the lid 10 is in the closed position, the lid may surround a transparent area, which may be formed, for example, by a glass or plastic plate.

[0060] The substrate 2 typically includes a bottom surface 3, a front wall 4, a rear wall 5, and two side walls 6 and 7, and is usually designed as a single unit. The rear wall 5 typically includes a substantially flat or straight section that connects to the side walls 6 and 7 via a curved transition region 8. The substrate 2 is typically made of a metallic material, preferably acid-resistant, rust-resistant, odorless, easy-to-clean, and dishwasher-safe, such as stainless steel, for example. In many cases, this represents the preferred material.

[0061] In addition to the optional transparent area, the cover 10 can also be made at least primarily of a metallic material, such as stainless steel, preferably. The cover 10 may include a handle 11, which facilitates opening and closing the cover 10 by hand.

[0062] The following description pertains to various aspects of container 1. According to a first aspect, at least one brake 50 is provided for braking (decelerating) the pivoting movement of the cover 10 and / or for holding the cover 10 in a position between a closed position and an open position. According to another aspect of the invention, at least one connecting module 20 is provided, which connects the cover 10 to the base 2. As described below, the brake 50 and the connecting module 20 can be coupled to each other.

[0063] First, the connection module 20 and its features will be described. Figure 6 An exemplary connection module 20 is shown in more detail, which demonstrates... Figures 1-5 Details of container 1. Figures 7-19 Further views, cross-sectional views, and exploded views of the connecting element 20 are shown.

[0064] The connecting module 20 enables a modular connection between the cover 10 and the base 2. In particular, the connecting module 20 can be detached from both the base 2 and the cover 10. Due to the modular connection, the components 2, 10, and 20 of the container 1 can be replaced, repaired, and / or cleaned individually.

[0065] The connecting module 20 includes at least one component 50 for realizing the pivotal movement of the cover 10. This component may specifically include, or be, a brake 50. Alternatively or additionally, the component may include, or may be, a motor element (not shown) for moving the cover 10 between a closed position and an open position. The connecting module 20 may include a housing 17, which includes a first housing portion 18 and a second housing portion 19, and the housing may accommodate the component 50.

[0066] The connection module 20 also includes a first connection element 21, which is detachably connected to the cover 10. The first connection element 21 typically includes a first shape-fitting element 22, which is designed as an elongated protrusion and can be connected to a first mating member 12, which is connected to or integrally formed on the cover 10 for forming a first shape fit, wherein the mating member 12 is shaped in a complementary manner to the first shape-fitting element 22.

[0067] Figure 20 Various views are shown of the shape-fitting element 12 or the mating member 12 connected to or integrally formed on the cover 10. In the exemplary embodiment shown, the first mating member 12 includes a first elongated receiving seat 13 that receives the first shape-fitting element 12 in a shape-locking manner. Due to the elongated shape of the first shape fit and the first shape-fitting element 22, the first connecting element 21 is non-rotatably connected to the cover 10. A first locking recess 14 may be formed in the first receiving seat 13 of the mating member.

[0068] The first form-fitting element 22 may be integrally formed with the first housing portion 18. Alternatively, the first form-fitting element 22 may also exist as a separate component connected to the first housing portion 18. The longitudinal axis 41 of the first form-fitting element 22 may be oriented at an angle relative to the pivot axis 40 of the cover 10, for example, vertically. The orientation of the longitudinal axis 41 also typically depends on the instantaneous opening angle of the cover 10.

[0069] Furthermore, a first spring-loaded pressure member 23 (spring plunger 23) is provided, which latches in the first locking recess 14 when a first form-fit is present. Therefore, the first spring-loaded pressure member 23 supports the retention of the first form-fit element 22 in the first receiving seat 13 of the mating member 12. The first mating member 23 is arranged in a recess 28, which is formed in the first form-fit element 22 and can be configured as a hole. Figure 7The diagram includes a partial cross-sectional view of the first pressure member 23. The pressure member 23 typically includes a sleeve 24, a compression spring 25, and an element 26 preloaded by the compression spring 25, which may be designed as a ball or pin, for example. The preloaded element 26 protrudes partially from the sleeve 24 and is typically held within the sleeve 24 by a protrusion 27 formed by the sleeve 24 and projecting radially inward. The sleeve 24 is attached to a recess 28. Alternatively, the sleeve 24 may be omitted. In this case, the spring 25 and the preloaded element 26 are arranged directly in the recess 28.

[0070] When the lid 10 is closed, the longitudinal axis of the first form-fitting element 22 and the longitudinal axis of the first container 13 are generally oriented perpendicular to gravity. When the lid 10 is open at a 90° angle, the aforementioned longitudinal axes of elements 22 and 13 extend parallel to gravity. If the lid 10 is lifted in this position, the pressure member 23 is released from the locking recess 14, thereby releasing the first form fit and allowing the lid 10 to be removed from the connecting module 20.

[0071] In the example shown, the first shape-fitting element 22 is therefore received by the first receiving seat 13 of the mating member 12. Alternatively, the first shape-fitting element may be configured to receive the mating member (not shown). In this case, the first shape-fitting element includes a first receiving seat, which preferably has a locking recess. In this case, the mating member is also configured as a protrusion that can be received in the first receiving seat in a shape-locking manner. The mating member attached to the cover may then include a first spring-loaded pressure member.

[0072] In addition, the connection module 20 includes a second connection element 31, which is detachably connected to the base 2.

[0073] The second connecting element 31 is shaped-fittedly connected to the second mating member 9 disposed on the base 2. For this purpose, the second connecting element 31 may have a second shape-fitting element 32, which can be connected to the second mating member 9 to form a second shape fit. The second mating member 9 and the second shape-fitting element 32 are complementaryly shaped and accommodate the second shape-fitting element 32 in a shape-fitting manner. In the illustrated embodiment, the second mating member is implemented by a bearing housing 9, wherein the second shape-fitting element 32 is configured as a stud. Therefore, reference will be made below to the bearing housing 9 and the stud 32. However, other complementary shapes are also conceivable for the second shape fit. The longitudinal axis 42 of the stud, i.e., the longitudinal axis of the second shape-fitting element 32, generally extends parallel to the pivot axis 40 of the cover 10, preferably perpendicular to the longitudinal axis 41, and generally perpendicular to gravity.

[0074] The bearing housing 9 typically has a second receptacle 15 that mates with the stud 32. A second locking recess 16 may be formed in the inner wall of the second receptacle 15.

[0075] Furthermore, a second spring-loaded pressure member 33 (spring plunger 33) can be mounted in the stud 32, which latches in the second locking recess 16 when a second form fit is present. The longitudinal axis of the second spring-loaded pressure member 33 generally extends at an angle relative to the longitudinal axis 42 of the stud 32, wherein the preferred angle is in the range of 80° and 100°, and particularly about 90°.

[0076] The second locking recess 16 can be configured as a through hole in the bearing housing 9, through which the second spring-loaded pressure member 33 extends. As a result, the user can access the second spring-loaded pressure member 33 from the outside and actuate it by pushing it with a finger. The second form-fit can then be released.

[0077] Optionally, a third spring-loaded pressure member 34 may be provided, which can be configured on the one hand to fix / align the second form-fit when the second pressure member 33 is locked in the second locking recess 16, and on the other hand to support the release of the second form-fit when the second pressure member 33 is pushed out of the second locking recess 16. The third spring-loaded pressure member 34 is preferably also mounted in the stud 32, but may alternatively be arranged in the second receiving seat 15 in the bearing housing 9. The third spring-loaded pressure member 34 is preloaded in the locked state of the second spring-loaded pressure member 33 and abuts against the inner wall of the second receiving seat 15. Optionally, the third spring-loaded pressure member 34 may engage in a third locking recess 35 formed in the receiving seat 15. In one embodiment, as is also clearly visible in the figures, the longitudinal axis of the third spring-loaded pressure member 34 extends parallel to the longitudinal axis 42 of the stud 32 and therefore perpendicular to the longitudinal axis of the second spring-loaded pressure member 33. When the second pressure member 33 is released from the second locking opening 16, the third spring-loaded pressure member 34 pushes the stud 32 at least partially out of the second receiving seat 15. In this way, during the actuation of the second spring-loaded pressure member 33, the connecting module 20 is displaced from the bearing seat 9 due to the spring force of the third spring-loaded pressure member 34, thereby providing the user with tactile and / or acoustic feedback that the connecting module 20 or the brake 50 has been released and is ready for removal.

[0078] The second pressure member 33 and / or the third pressure member 34 may have a design similar to the first pressure member 23. For example, the respective pressure members 33, 34 may include a sleeve, a compression spring, and an element preloaded by the compression spring, which may be designed as a ball or pin, for example. The preloaded element typically protrudes partially from the sleeve and is held within the sleeve by a protrusion formed by the sleeve and projecting radially inward.

[0079] In the illustrated embodiment, the second shape-fitting element 32 is thus received in a shape-locked manner by the second receptacle 15 of the bearing housing 9. Alternatively, the second shape-fitting element may be configured to receive a mating member (not shown). In this case, the second shape-fitting element includes a second receptacle, which preferably has a second locking recess. In this case, the mating member is also configured as a protrusion that can be received in the second receptacle in a shape-locked manner. Thus, the protrusion attached to or formed on the base 2 may include a second spring-loaded pressure member and a third spring-loaded pressure member.

[0080] The connection module 20 may include a rigid center member 29, which is connected at a first end to a first connection element 21 and / or housing 17 and at an opposite end to a second connection element 31.

[0081] exist Figures 1-5 Two connecting modules 20 are arranged in the container 1, mirror-symmetrically to each other. The plane of mirror symmetry generally extends parallel to the sidewalls 6, 7. The longitudinal axes 42 of the second shape-fitting elements 32, configured as studs, are preferably opposite to each other and thus oriented in opposite parallel directions. To release the corresponding second shape-fitting element, the stud 32 must be pulled out of the second housing 15 in the opposite direction. The longitudinal axes 41 of the first shape-fitting elements 22 are preferably oriented parallel to each other and pointing in the same direction. The first shape-fitting element can be released simultaneously by pulling the lid or lifting the lid 10, preferably at an opening angle of approximately 90°. Due to the orientation of the longitudinal axes 41, 42, the second shape-fitting element can also be released only after the lid 10 has been removed from the corresponding connecting module 20. This prevents the connecting modules 20 from being unintentionally loaded into the dishwasher along with the lid 10. In this way, the components 50, which are generally sensitive to water and / or detergents, are protected and their service life is extended.

[0082] As described above, each connecting module 20 is connected to the base 2 via a bearing seat 9, which is preferably welded to the base 2. Each bearing seat 9 is preferably arranged on the upper side of the flat portion of the rear wall 5. Furthermore, the bearing seat 9 is preferably adjacent to the transition region 8 and thus located on the outer side of the rear wall 5 (on the right or left outer side). The outward mounting connection of the connecting modules 20 is due to the flexural stiffness of the side walls 6, 7 and / or the transition region 8. This prevents the rear wall from bending during opening and closing and eliminates the need for additional rear wall reinforcement.

[0083] The brake 50 will be described in more detail below. The brake 50, configured as a friction brake, is set to decelerate the pivoting movement of the cover 10 and hold the cover 10 in a position between a closed position and an open position. The cover 10 can be held in multiple positions between the closed and open positions by means of the brake 50, preferably in an infinitely adjustable manner.

[0084] Brake 50 includes flywheel 52, which defines a blocking direction 44 and a sliding direction 45. The blocking direction 44 corresponds to the closing direction of cover 10, and / or the sliding direction 45 corresponds to the opening direction of cover 10. In other words, flywheel 52 is coupled to the pivoting motion of cover 10, such that brake 50 decelerates or holds cover 10 in the closing direction but not in the opening direction. Flywheel 52 may, for example, be configured as a one-way roller clutch.

[0085] The cover 10 is coupled to a rotatable shaft 54 ​​that defines a rotation axis or pivot axis 40. The shaft 54 ​​may have a non-circular protrusion 56 extending in the axial direction and engaging in a form-locking manner in a corresponding recess 57 in the first housing portion 18. Attachment devices such as screws 55 may be provided to attach the shaft 54 ​​to the first housing portion 18.

[0086] Optionally, a bearing bushing 58 may be provided around the shaft 54. The bearing bushing 58 may define the internal space of the brake 50 in which the flywheel 52 is disposed. The flywheel 52 is preferably arranged radially between the bearing bushing 58 and the shaft 54. In the example shown, the flywheel 52 is arranged directly on the shaft 54, so there are no other components between the flywheel 52 and the shaft 54. In addition, two rolling bearings 60 are provided, arranged on both sides of the flywheel 52 on the shaft 54. The rolling bearings 60 may be designed as slotted ball bearings, for example, and are generally arranged radially between the bearing bushing 58 and the shaft 54. The rolling bearings 60 allow the shaft 54 ​​to rotate relative to the bearing bushing 58.

[0087] Optionally, the bearing bushing 58 may have a circumferential, radially inwardly oriented protrusion 61, which typically abuts the rolling bearing 60 on one side and the flywheel 52 on the other in the axial direction. Two retaining rings 66 may be provided, each abutting the ball bearing 60 and forming the axial boundary of the ball bearing 60. The bearing bushing 58 may also have a radially outwardly oriented shoulder 59. The rolling bearing 60 is also arranged within the internal space defined by the bearing bushing 58.

[0088] Shaft 54 ​​may have multiple steps that extend radially and are arranged adjacent to each other in the axial direction. Elements 53, 50, and 66 may be arranged on steps with different radial heights.

[0089] The first cover 62 may be configured to cover the internal space of the brake 50 surrounded by the bearing bushing 58. The bearing bushing 58 may be non-rotatably connected to the first cover 62, for example, by a screw 63 engaged in a shoulder 59. For sealing, a sealing element 64, such as an O-ring, formed of an elastic material, may be provided between the bearing bushing 58 and the first cover 62. For further sealing, another sealing element, such as a radial shaft sealing ring 65, may be provided radially between the cover 62 and the shaft 54. The radial shaft sealing ring 65 defines an area 53 filled with a lubricant such as grease for lubrication and further sealing (see reference). Figure 16 ).

[0090] Thanks to the O-ring 64 and the radial shaft seal ring 65, the internal space of the brake 50 is adequately protected from water and moisture, and the one-way roller clutch 52 and ball bearing 60 are located in this internal space.

[0091] The bearing bushing 58 can be connected to the second cap 68 on the opposite axial side. Therefore, the first cap 62 and the second cap 68 can be arranged on opposite axial sides of the bearing bushing 58. The second cap 68 preferably has internal threads for this purpose, which can be screwed onto the external threads of the bearing bushing 58. A spacer ring 67 or spacer sleeve can be axially arranged between the second cap 68 and the bearing bushing. A retaining O-ring 69 can be axially disposed between the second cap 68 and the second housing portion 19. This O-ring is used to seal external liquids that could otherwise seep into element 68 through the small threads. Preferably, for example, a sealant can be provided at least in the area between elements 68, 67, and 58 to seal this area against external moisture.

[0092] The first cover 62 and the second cover 68, together with the bearing bushing 58, can be interpreted as the inner housing, while the first housing portion 18 and the second housing portion 19 can be interpreted as the outer housing.

[0093] Figure 11 An exploded view of the brake 50 or connecting module 20 is shown. Figure 11 As can be seen, the bearing bushing 58 typically includes a circular portion and a flat portion along the circumferential direction on its radially outer side. The flat portion of the bearing bushing 58 is particularly suitable for mates with the rotationally fixed shape of components arranged on the bearing bushing 58.

[0094] Brake 50 may also include at least one brake pad 70, preferably two brake pads 70, and a brake disc 72. The term "brake disc" as used in this specification is similar to a disc brake selection in a vehicle and is due to the disc shape of element 72. However, unlike disc brakes used in vehicles, the brake pads 70 rotate while the brake disc 72 remains stationary. Instead of the term "brake disc," terms such as "brake lever" or "brake arm" may also be used.

[0095] Brake pads 70 are typically arranged on bearing bushings 58 and may include a flat portion on their inner side to allow for a form-fit with bearing bushings 58 for rotational fixation. Brake discs 72 are typically fixedly connected to a rigid center member 29 and are thus arranged to be stationary relative to the base 2. Brake pads 70 are arranged axially on both sides of the brake disc 72. Preferably, spring elements 74 are provided that push the brake pads 70 and brake disc 72 together axially. Spring elements 74 may be designed, for example, as wave springs. Adjusting washers 73 may be arranged between the brake pads 70 and spring elements 74 to evenly distribute the spring force of spring elements 74 onto the brake pads 70. Another washer 75 may be form-fitted onto the opposite axial side of spring elements 74, abutting against the end face of the second cover 68. The function of this washer 75 is to prevent the wave spring 74 from twisting when the second cover 68 is screwed on. The sliding bearing 76 can be arranged radially between the brake disc 72 and the bearing bush 28, which allows the bearing bush 58 to rotate relative to the brake disc 72.

[0096] The maximum possible opening angle of the cover 10 can be established by a stop 48 present at the center member 29, which is sometimes referred to as the nose. Therefore, the stop 48 restricts the pivoting movement of the cover 10. The stop 48 engages in a groove-shaped recess 49, which extends axially and circumferentially, for example, between the brake disc 72 and the first housing portion 18.

[0097] The following is based on Figure 16 Describe the working mechanism of a device similar to brake 50. Figure 16 A cross-section of the brake 50 and the connecting module 20 is shown, which are connected to the left side of the container 1. Figure 10 The brake 50 and connecting module 20 are attached to the right side of container 1. Furthermore, Figure 16 The brake 50 is designed to be slightly shorter in the axial direction than Figure 10 Brake 50. Functionally equivalent features are indicated by the same reference numerals, and repeated descriptions are omitted here.

[0098] Figure 16 Two force flows are depicted using arrows 46 and 47. Arrow 47 represents the force flow when cover 10 is open, while arrow 46 represents the force flow when cover 10 is closed.

[0099] As described above, the cover 10 is non-rotatably connected to the first housing portion 18 and the shaft 54 ​​by means of a first form-fitting element 22. The opening direction of the cover 10 corresponds to the sliding direction 45 of the shaft 54 ​​and the flywheel 52, so that when the cover 10 is opened, the shaft 54 ​​rotates accordingly. When the cover 10 is open, torque is therefore not transmitted to the braking mechanism, and thus the brake 50 is not actuated in this situation. In this way, in particular, components 19, 58, 68, and 70 do not rotate together. At least one brake pad 70 and brake disc 72 are stationary relative to each other in the sliding direction 45 of the shaft 54.

[0100] Conversely, if the cover 10 rotates from the open position to the closed position, the rotation of the shaft 54 ​​is transmitted from the flywheel 52 to the bearing bushing 58 via a press fit. Torque is introduced from the bearing bushing 58 to the brake pad 70 by means of a form fit. The brake pad 70 is pressed against the axial end face of the brake disc 72 by a spring element 74. In the blocking direction 44 of the shaft 54, the relative movement of the brake pad 70 and the brake disc 72 is slowed (brakeed), and thus braking is achieved through friction between the brake pad 70 and the brake disc 72. In summary, the rotation of the shaft 54 ​​and the pivoting movement of the cover 10 are thus slowed. The force applied to the brake disc 72 flows out via the center member 29 and the second connecting element 21 to the bearing seat 9 and the container 1. If no manual force is applied, and only gravity acts on the cover 10, the brake 50 ensures that the cover 10 remains in its position. The braking force is preferably designed such that the cover 10 is held in a steplessly variable manner, with no play in each position between the closed and open positions. This also means that a small amount of manual force is required to close the cover 10 to overcome the holding force of the brake 50. This required manual force is greatest at approximately 90° when the cover 10 is fully open, and decreases steadily as the cover 10 is closed due to the increasing effect of gravity.

[0101] A sliding bearing 76 arranged between the brake disc 72 and the bearing bushing 58 allows for relative rotational movement of the bearing bushing 58 relative to the brake disc 72. When the cover 10 is closed, the components 19, 58, 68, 70 therein and the components that are non-rotatably connected to them also rotate.

[0102] Figure 17 A longitudinal cross-sectional view of a similar brake 50 is shown, which has a larger... Figure 10 The cross-sectional view in the diagram shows a simpler design for brake 50. Figure 17 In this drawing, the same features are indicated by the same reference numerals, and repeated descriptions are omitted here.

[0103] The brake 50 includes a flywheel 51, which is configured as a one-way roller clutch and integrates two rolling bearings therein. In this way, [the following can be omitted]: Figure 10 A separate rolling bearing 60. Furthermore, in Figure 17 In this embodiment, the first cover 62 is omitted. An optional radial shoulder 30 of the shaft 54 ​​defines the flywheel 51 in the axial direction, thus omitting the retaining ring 66 in this area. On the other side of the shaft 54, an adjusting washer 77 is axially arranged between the retaining ring 66 and the flywheel 51. Overall, Figure 17 The brake 50 is therefore more Figure 10 The brake 50 requires fewer parts; see also [link to other brake models]. Figure 18 An exploded view of brake 50.

[0104] Figure 19 Another embodiment of the brake 50 is shown, which discloses a longitudinal cross-sectional view of the brake 50.

[0105] Figure 19 The brake is similar to Figure 17 The brake 50 has the effect of integrating the rolling bearing into the flywheel 51, thus eliminating the need for... Figure 10 The first cover 62 of the brake 50. However, instead of Figure 17 The radial shaft seal ring 65, in Figure 19 An optional sealing ring 78 is provided in the brake, which radially seals the system relative to the outside. The sealing ring 78 is typically located between the brake disc 72 and the first partial housing 18. The sealing ring 78 is preferably recessed in a groove 79 of the brake disc 72. Another sealing ring 78 may be arranged between the brake disc 72 and the second partial housing 19, preferably also arranged in a groove 79 of the brake disc 72. Since the sides of the partial housings 18, 19 that are in contact with each other move radially relative to the seal 78, a square sealing ring can be arbitrarily selected for the seal 78, which typically has a lubricant container, thereby minimizing friction. Sealant and / or additional sealing elements for sealing may also be provided in the area of ​​the screw 55 and / or between the shaft 56 and the support shoulder of the first housing portion 18 to shield the system from moisture from the outside.

[0106] Figure 19 Another distinctive feature of this embodiment is the omission of the second cover 68. Instead, the second housing portion 19 is typically directly connected to the bearing bushing 58 via a threaded connection. This reduces the number of components required.
