Description

Technical Field

[0001] The present invention relates to fastening elements for covers, and more particularly to various designs of fastening elements for bathroom fixtures, wherein the bathroom fixtures are particularly suitable for use by a person in a toilet (such as a bathroom) for showering, bathing and / or body cleaning. Background Technology

[0002] In bathroom fixtures such as shower units or bathtubs, large ceiling-mounted shower units (also known as recessed showers) with covers are used. As the only visible part of the ceiling shower unit, the cover conceals the shower components and mounting box located in the room's ceiling, while also meeting high aesthetic requirements, as this type of shower is typically a high-priced product in the high-end market. Therefore, visible fastening elements for the cover create unacceptable aesthetic intrusion. Permanent fixation of the cover is not permissible because the shower components located behind or covered by it must be accessible. Furthermore, due to manufacturing challenges, the cover needs to be made of a material with sufficient shape stability (such as metal), for example, using zinc die-casting methods. Therefore, due to its weight, a sufficiently strong and stable fixation of the cover is crucial.

[0003] Similarly, it is impossible to fasten it to the water-conducting functional components because the stability of the connection is affected by certain hydrodynamic factors.

[0004] Therefore, securing heavy covers (e.g., over 500 grams) to a concealed box or fastener (e.g., due to its placement on the ceiling, making it difficult to access) must meet the following conditions:

[0005] • Securely fastened (meaning it cannot come loose on its own);

[0006] • The fastening components are not visible (or cannot be seen);

[0007] • Easy to install; and

[0008] • Removable (and reinstallable and removable).

[0009] Known solutions for invisible connections include magnets, clips, or latches, but their mechanical properties are insufficient due to gravity. Other known connections, such as screw connections (front, side), are generally undesirable because they are visible and therefore conflict with aesthetic requirements. Summary of the Invention

[0010] Therefore, the object of the present invention is to at least partially solve the problems described with reference to the prior art, and in particular to provide a fastening element for a cover, which is particularly useful in bathroom fixtures and preferably for fastening a cover to a ceiling-mounted shower.

[0011] This objective is achieved by a fastening element according to the features described in independent claims 1, 9, and 12. Other advantageous designs of the invention are given in the dependent claims. It should be noted that the features listed individually in the dependent claims can be combined with each other in any technically reasonable manner and define further designs of the invention. Furthermore, the features given in the claims are described and explained in more detail in the specification, wherein further preferred designs of the invention are shown.

[0012] A fastening element for a cover is proposed.

[0013] This fastening element and cover are particularly useful in bathroom fixtures and are especially suitable for ceiling-mounted showers.

[0014] The fastening element (according to the first design) has at least the following characteristics:

[0015] -First element; and

[0016] - A second element arranged at the first element in such a way that it can swing at least between a first position and a second position.

[0017] In the first position, the second element is arranged to be preloaded by a stop mechanism of the first element, wherein the stop mechanism can be canceled by elastic deformation of the first element, and the second element can swing toward the second position by at least partially reducing the preload.

[0018] The stop mechanism, in particular, prevents oscillation from the first position to the second position by means of a form-locking mechanism. In particular, the stop mechanism cannot be canceled by a force acting in the oscillation direction (at least without plastic deformation of the first element) (i.e., canceling the locking effect of the stop mechanism in preventing the second element from oscillating toward the second position).

[0019] In particular, the fastening element (according to the first design) has at least one energy storage element for generating preload. This energy storage element may be, for example, a force spring, a compression spring, a helical spring, a pneumatic energy storage device, or other elements that are elastically deformable and simultaneously store deformation energy.

[0020] In particular, one of the elements has at least one first pin, and the other of the elements has a receiving portion for the first pin. In order to manufacture the fastening element, the second element can be pushed into the recess of the first element along a first direction until at least one first pin is arranged in the receiving portion and thereby forming a rotation axis for the second element to swing.

[0021] In particular, the push-in allows for elastic deformation of one of the components, thereby locking at least one first pin in the receiving portion.

[0022] In particular, the second element has at least one first pin and the first element has a notch or receiving portion. In particular, the second element has two first pins.

[0023] In particular, the stop mechanism is composed of two stop elements, each of which is arranged at the protrusion of the first element. In order to cancel the stop mechanism, the protrusion can be elastically deformed and can move away from each other in an opening motion.

[0024] In particular, the direction of rotation of the oscillation extends perpendicular to the direction of the opening motion of the protrusion. In particular, the axis of rotation extends substantially parallel to the direction of the opening motion.

[0025] In particular, the first direction extends transversely to the axis of rotation.

[0026] In particular, the stop mechanism prevents the second element from swinging back to the first position, at least by force-locking. Therefore, in particular, the force-locking of the stop mechanism can be overcome by an operating force acting in the direction of swing, wherein at least part of the plastic deformation of one of the elements does not occur.

[0027] In particular, the second element can be swung from the second position to the first position by applying a manipulating force acting on the manipulating element of the second element and in the direction of rotation of the swing. Specifically, by this manipulating force, the protrusion elastically deforms (if necessary to release the force-locking of the stop mechanism) and moves away from each other in an opening motion. Here, the surface of the second element that interacts with the stop element or the protrusion can, for example, be designed as an inclined plane, so that the protrusion opens further as the swing of the second element relative to the first element increases.

[0028] However, it is preferable that the stop element only forms a stop mechanism when swinging toward the second position, and thus does not prevent it from swinging back to the first position. This, for example, achieves the effect of loosening the cover from the fastening element by (only) overcoming the elastic action of the energy storage element.

[0029] Furthermore, a fastening device for a lid is proposed. This fastening device has at least the following features:

[0030] - Fastening plate;

[0031] - Cover; and

[0032] - At least one of the fastening elements (according to the first design) used to secure the cover to the fastening plate.

[0033] The fastening element (according to the first design) is fastened to the fastening plate via the first element (e.g., by riveting or screw connection). The cover has at least one protrusion that, during cover installation, causes the first element to elastically deform and thereby cancels the stop mechanism, allowing the second element, preloaded and positioned in the first position, to swing relative to the first element and establish a connection with the protrusion to fasten the cover to the fastening plate.

[0034] A fastening element for a cover (according to the second design) has at least:

[0035] -First element;

[0036] - A second element arranged at the first element in such a way that it can swing (and move additionally if necessary) between the first and second positions;

[0037] - A third element disposed at the first element and movable relative to the first element (only); and

[0038] - An energy storage element designed as a spring element.

[0039] If the third element is moved, it contacts the second element and causes the second element to oscillate, wherein the spring element is arranged between the first and second elements such that the second element oscillates against the elastic action of the spring element.

[0040] In particular, the second element can be locked in the first position by the first element, and can be locked in the second position by the third element.

[0041] Furthermore, another fastening device for a lid is proposed. This fastening device has at least the following features:

[0042] - Fastening plate;

[0043] - Cover; and

[0044] - At least one of the fastening elements (according to the second design) used to secure the cover to the fastening plate.

[0045] The fastening element (according to the second design) is fastened to the fastening plate by means of the first element (e.g., by riveting or screw connection). The cover has at least one protrusion that, during the installation of the cover, contacts the third element and moves the third element, thereby causing the third element to contact the first element and swing the first element to a second position, in which the second element establishes a connection with the protrusion to fasten the cover to the fastening plate.

[0046] A fastening element for a cover (according to the third design) has at least:

[0047] -First element;

[0048] - A second element arranged at the first element in such a way that it can (only) swing between the first and second positions;

[0049] - A third element disposed at the first element and movable relative to the first element (only); and

[0050] - An energy storage element designed as a spring element.

[0051] If the second element is swung, it contacts the third element and causes the third element to move, wherein the spring element is arranged between the first and third elements such that the movement of the third element is overcome by the elastic action of the spring element.

[0052] In particular, the second element is locked in the first and second positions by the third element.

[0053] Furthermore, another fastening device for a lid is proposed. This fastening device has at least the following features:

[0054] - Fastening plate;

[0055] - Cover; and

[0056] - At least one of the described fastening elements (according to the third design) used to fasten the cover to the fastening plate.

[0057] The fastening element (according to the third design) is fastened to the fastening plate by means of the first element (e.g., by riveting or screw connection). The cover has at least one protrusion that, during the installation of the cover, contacts the second element and causes the second element to swing to a second position, wherein, in the second position, the second element establishes a connection with the protrusion to fasten the cover to the fastening plate.

[0058] In particular, each of the described fastening devices also has at least one liquid discharge device, wherein the discharge device is arranged between the fastening plate and the cover.

[0059] The drain device is connected, for example, to a water supply line, so that water can be discharged to the user of the bathroom fixtures via the drain device and through a cover. In particular, the drain device has multiple outlets through which water can flow out of the drain device. Specifically, each outlet of the drain device is associated with an opening in the cover, so that water can be discharged from the drain device and through the corresponding opening to the user.

[0060] In particular, the fastening plate extends in a first plane and the cover extends in a second plane, wherein a plurality of fastening elements are provided between the two planes (according to the first and / or second and / or third design schemes), wherein the cover is movable along an installation direction extending transversely to the plane, wherein the protrusions are respectively connected to the fastening elements.

[0061] In particular, each protrusion is associated with a fastening element.

[0062] In particular, the protrusion contacts the protrusion of the first element of the fastening element according to the first design, and forces the protrusion to open during the displacement of the cover along the mounting direction. This cancels the locking action of the stop mechanism and causes the second element to swing from the first position to the second position. Specifically, the second element works in conjunction with the protrusion to establish a form-locking connection between the cover and the fastening element relative to the mounting direction.

[0063] In particular, the second element of the fastening element according to the first design works in conjunction with the protrusion so that as the swing of the second element increases, the cover continues to shift along the installation direction during the lifting movement.

[0064] In the fastening element according to the first design, in the second position of the second element, the protrusion restores its shape to such an extent that the stop element forms a stop mechanism that acts as a force-locking mechanism, preventing it from swinging back toward the first position.

[0065] In order to swing back, it is especially necessary to operate the second element by means of a manipulating force, so as to overcome the locking of the force lock of the stop mechanism.

[0066] In the fastening element according to the second design, in particular, the second element is contacted by the third element (moved by the protrusion), and the second element is swung from the first position to the second position.

[0067] Here, especially firstly, the oscillation increases the spring force of the spring element. This is ensured by the position of the spring element and its points of application at the first and second elements.

[0068] Alternatively, only sliding occurs between the first element (and the stop mechanism constructed thereon) and the second element (and the first pin constructed thereon and acting in conjunction with the stop mechanism); thus, the spring force of the spring element is not increased during this period.

[0069] In the fastening element according to the second design, the second element has at least one first pin, and the first element has an elongated first guide rail, into which the first pin extends. For manufacturing the fastening element, the first element is particularly designed as a two-piece unit, wherein a second element and a third element (and possibly a spring element) are arranged between the halves of the first element.

[0070] The first pin is arranged in the first guide rail and thereby forms a rotation axis for the swinging of the second element.

[0071] The third element is arranged at the first element in a way that is not easily lost, and is movable only in one direction. This mobility is achieved by a second pin at the third element and a second guide rail at the first element, the second pin engaging in the second guide rail and being guided by the second guide rail.

[0072] In particular, when swinging to the second position, the locking of the second element present in the first position (and caused by the first element) is first released. In particular, when the second element swings about the first pin (in the direction of rotation), the first pin also moves, thereby at least partially reducing the spring force of the higher spring element present in the first position.

[0073] The third element prevents the swing back from the second position to the first position, in which the third element is arranged to move and contact the second element.

[0074] In order to swing back, it is especially necessary to manipulate the second element by means of a manipulating force (i.e., to move it first and then swing it), so that the preload can be overcome and the third element can be moved.

[0075] In the fastening element according to the second design, in particular, the second element is contacted by the third element (moved by the protrusion), and the second element is swung from the first position to the second position.

[0076] In the fastening element according to the third design, in particular one of the first and second elements has at least one first pin, while the other of the first and second elements has a receiving portion, wherein the first pin extends into the receiving portion and forms a rotation axis. In order to manufacture the fastening element, the first element is particularly designed as a two-piece, wherein the second and third elements (and possibly a spring element) are arranged between the two halves of the first element.

[0077] The first pin is arranged in the receiving part, thereby forming a rotation axis for the second element to swing.

[0078] In particular, when swinging to the second position, the latch of the second element that was present in the first position (and caused by the third element) is first released.

[0079] In particular, the second element has circumferential surfaces that extend at an angle to each other, which contact the preloaded third element. When the second element oscillates, it oscillates relative to the first and third elements along the direction of rotation. Here, the elasticity of the spring element overcomes the elasticity of the third element, causing it to shift, and the contact between the second and third elements shifts to the (other inclined) circumferential surface that is closest in the direction of rotation.

[0080] A third element prevents the element from swinging back to the first position from the second position, and the third element contacts the second element arranged in the second position via a circumferential contact.

[0081] In order to swing back, it is especially necessary to manipulate the second element by means of a manipulation force (i.e., simply rotate it in the direction of rotation), so as to overcome the preload and the elastic effect of the spring element to move the third element.

[0082] Bathroom fixtures, especially those for personal hygiene, are used in various ways. For this purpose, bathroom fixtures can be constructed, for example, in the form of a shower or bathtub and / or arranged in a toilet (such as a bathroom). Furthermore, bathroom fixtures can be used for therapeutic purposes. Bathroom fixtures have at least one drainage device for liquids. This at least one drainage device can be, in particular, a shower head, an overhead shower, a ceiling-mounted shower, a nozzle, and / or a water outlet. Liquids, especially water, can be discharged into at least one basin (collection device) of the bathroom fixture through at least one outlet of the drainage device.

[0083] The basin or collection device can be configured, in particular, as a shower tray or bathtub. Furthermore, the basin can be fixed in position, for example, arranged or secured to the building floor. In particular, the basin has a drain outlet for liquids, through which liquids can be conveyed, in particular, to the public sewer system.

[0084] Furthermore, the bathroom fixtures particularly include a thermostat (in the simplest embodiment, a mixing device without its own temperature control), through which hot and cold water can be mixed into water of a regulated temperature. The hot and cold water are both fresh water and can be mixed by the thermostat to form a mixed water with a desired temperature. The hot water temperature can be, in particular, up to 90°C, preferably 25°C to 90°C, particularly preferably 55°C to 65°C, and / or the cold water temperature can be, in particular, up to 25°C, preferably 1°C to 25°C, particularly preferably 5°C to 20°C. The desired temperature of the liquid output through the discharge device can be, for example, 30°C to 50°C, preferably 35°C to 45°C, particularly preferably 35°C to 40°C.

[0085] For example, hot water can be supplied to the thermostat from a hot water source (such as a boiler, a (private and / or local) solar thermal system, or a heat pump) via hot water pipes, and / or cold water can be supplied to the thermostat from a cold water source (such as a building water supply connection, a public water supply network, or a (private and / or local) well) via cold water pipes. The hot water pipes and / or cold water pipes can be at least partially constructed in the form of conduits. Furthermore, the hot water pipes and / or cold water pipes can extend at least partially through building walls and / or building floors. The thermostat can have a hot water inlet for hot water and / or a cold water inlet for cold water. Hot water pipes can be connected to the hot water inlet and / or cold water pipes can be connected to the cold water inlet. Additionally, the thermostat can be at least partially embedded in the building walls or building floors.

[0086] The mixing pipe may be at least partially constructed in the form of a pipe and / or hose and is fluidically connected to the discharge device.

[0087] The desired temperature of the liquid discharged through the discharge device can be adjusted by the user of the bathroom fixtures, for example, through the operating elements of the bathroom fixtures and / or thermostats.

[0123] Figure 1 The fastening plate 21 is shown in a top view. Figure 2 The discharge device 23 is shown in a three-dimensional view. Figure 3 Cover 2 is shown in a three-dimensional view. Figure 4 The second element 4 of the fastening element 1 according to the first embodiment variant is shown in a perspective view. Figure 5 The first element 3 of the fastening element 1 according to the first embodiment variant is shown in a perspective view. Figure 6 Two energy storage elements 6 of the fastening element 1 according to the first embodiment variant are shown in a perspective view. Figure 7 The fastening element 1 according to the first embodiment variant is shown in a perspective view. Figure 8 The fastening device 20 is shown in a top view. It is described below together. Figures 1 to 8 .

[0124] The fastening device 20 for the cover 2 includes a fastening plate 21, the cover 2, and a plurality of fastening elements 1 for fastening the cover 2 to the fastening plate 21.

[0125] According to the first embodiment variant (corresponding to the first design), the fastening element 1 includes a first element 3 and is at least in a first position (see...) Figure 9 and Figure 10 ) and second position (see Figure 11 and Figure 12 The second element 4 is arranged at the first element 3 in a swinging manner between the two elements.

[0126] In the first position, the second element 4 is arranged to be preloaded by the stop mechanism 5 of the first element 3, wherein the stop mechanism 5 can be canceled by elastic deformation of the first element 3, and the second element 4 can swing toward the second position by at least partially reducing the preload.

[0127] The stop mechanism 5 prevents oscillation from the first position to the second position by means of a form-locking mechanism. The stop mechanism 5 cannot be canceled by a force acting in the oscillation direction (e.g., the operating force 19), that is, the locking effect of the stop mechanism 5 in preventing the second element 4 from oscillating toward the second position cannot be canceled. At least, the locking effect cannot be canceled if the first element 3 does not undergo plastic deformation.

[0128] The fastening element 1 has two springs as energy storage elements 6 for generating preload. The springs are designed as helical springs, wherein one end of the helical spring is supported at the first element 3 and the other end is supported at the second element 4.

[0129] The second element has two first pins 7. The first element 3 has a receiving portion 8 for each first pin 7. In order to manufacture the fastening element 1, the second element 4 can be arranged along a first direction 9 (see example). Figure 5 , 7 9) is pushed into the notch 10 of the first element 3 until the first pin 7 is arranged in the corresponding receiving part 8 and thus forms a rotation axis 11 for the swing of the second element 4.

[0130] By pushing in, the first element 3 can be elastically deformed at least partially, so that the first pin 7 can be locked in the corresponding notch 8.

[0131] The stop mechanism 5 is constituted by two stop elements 12 and 13, wherein each stop element 12 and 13 is arranged at the protrusions 14 and 15 of the first element 3. In order to cancel the stop mechanism 5, the protrusions can elastically deform and simultaneously open with an opening movement 16 (see Figure 12 They move away from each other.

[0132] The direction of rotation 17 of the swing extends perpendicularly to the direction of the opening movement 16 of the protrusions 14 and 15. The axis of rotation 11 extends substantially parallel to the direction of the opening movement 16. The first direction 9 extends transversely to the axis of rotation 11.

[0133] The stop mechanism 5 locks the second element 4 from the second position back to the first position by at least (only) force-locking. That is, in particular, the force-locking of the stop mechanism 5 can be overcome by an operating force 19 acting in the direction of the swing, wherein at least part of the plastic deformation of one of the elements 3 and 4 does not occur (see below for...). Figure 11 and Figure 12 (Description).

[0134] By applying a control force 19 acting on the control element 18 of the second element 4 and in the direction of rotation 17 of the swing (see... Figure 7 This allows the second element 4 to swing from the second position to the first position, wherein, by the actuating force 19, the protrusions 14 and 15 can elastically deform to release the force-locking of the stop mechanism 5, and here they can move away from each other by the opening movement 16. Here, the surface of the second element 4 that interacts with the stop elements 12 and 13 or the protrusions 14 and 15 can be designed, for example, as an inclined plane, so that the protrusions 14 and 15 further open as the swing of the second element 4 relative to the first element 3 increases.

[0135] Fastening element 1 is fastened to fastening plate 21 by first element 3 (e.g., by riveting or screw connection). Cover 2 has a plurality of protrusions 22 that, during the installation of cover 2, cause the corresponding first element 3 (specifically its protrusions 14, 15) to elastically deform, thereby canceling the stop mechanism 5, causing second element 4, which is preloaded and positioned in a first position, to swing relative to first element 3, and establishing a connection with the protrusions 22 to fasten cover 2 to fasten it to fastening plate 21.

[0136] Additionally, the fastening device 20 has a discharge device 23 for liquid 24, wherein the discharge device 23 is arranged between the fastening plate 21 and the cover 2.

[0137] The drain device 23 is connected, for example, to a water supply line, so that water (liquid 24) can be discharged to the user of the bathroom fixture via the drain device 23 and through the cover 2. The drain device 23 has a plurality of outlets 28 through which liquid 24 can flow out from the drain device 23. Here, each outlet 28 of the drain device 23 is associated with an opening 30 in the cover 2, so that liquid 24 can be discharged from the drain device 23 and through the corresponding opening 30 to the user.

[0138] The fastening plate 21 extends in the first plane 25, and the cover 2 extends in the second plane 26. A plurality of fastening elements 1 are arranged between the planes 25 and 26. The cover 2 is movable along an installation direction 27 extending transversely to the planes 25 and 26, and protrusions 22 are respectively connected to fastening elements 1 (this also applies to the second and third embodiments). Each protrusion 22 is associated with one fastening element 1.

[0139] Figure 9 The side view shows the results according to Figure 8 Details of the fastening device 20, wherein the fastening element 1 is in the first position. Figure 10 A three-dimensional diagram is shown based on Figure 9 Details. Figure 11 The side view shows the results according to Figure 8 Details of the fastening device 20, wherein the fastening element 1 is in the second position. Figure 12 A three-dimensional diagram is shown based on Figure 12 Details. The following describes them together. Figures 9 to 12 Reference Figures 1 to 8 Detailed explanation.

[0140] Figure 9 and 10 The fastening device 20 is shown before a connection is established between the protrusion 22 and the fastening element 1. According to a first embodiment, the fastening element 1 is fastened to the fastening plate 21 by a first element 3 (e.g., by riveting or screw connection, not shown). The cover 2 has a protrusion 22 that, during the installation process of the cover 2, causes the corresponding first element 3 (specifically its protrusions 14, 15) to elastically deform, thereby causing the protrusions to move away from each other during the opening movement 16. Due to the opening movement 16 pushed by the side edges of the protrusion 22, the stop elements 12, 13 also move away from each other during the opening movement 16, thus canceling the stop mechanism 5. Therefore, the second element 4, preloaded by the energy storage element 6 in the first position, can swing relative to the first element 3, and a connection is established with the protrusion 22 to fasten the cover 2 to the fastening plate 21. A connection is established with the protrusion 22 via a locking hook, wherein the second element 4 forms a locking connection with the window 31 in the protrusion 22 relative to the mounting direction 27 (see [link]). Figure 12 Here, the second element 4 works in conjunction with the protrusion 22 such that as the swing of the second element 4 increases, the cover 2 continues to move toward the fastening plate 21 along the mounting direction 27 during the lifting movement 29.

[0141] exist Figure 11 and Figure 12The image shows a fastening device 20 after a connection has been established between the protrusion 22 and the fastening element 1 according to a first embodiment variant. The connection with the protrusion 22 is established by a snap-lock hook connection, wherein the second element 4 forms a locking connection with the window 31 in the protrusion 22 relative to the mounting direction 27.

[0142] When the stop elements 12 and 13 reform the stop mechanism 5, the protrusions 14 and 15, which elastically restore their shape, prevent the element from swinging back toward the first position. Accordingly, the second element 4 can be shaped so that the protrusions 14 and 15 can swing back to such an extent that the stop elements 12 and 13 form the stop mechanism 5 for the second element 4, preventing the second element from swinging toward the first position along the rotation direction 17.

[0143] Therefore, the stop mechanism 5 prevents the second element 4 from swinging back to the first position, at least by force locking. Here, the force locking of the stop mechanism 5 can only be overcome by applying a sufficiently high operating force 19 in the direction of swing, wherein at least partial plastic deformation of one of the elements 3 and 4 does not occur. For example, by acting on the operating element 18 (see...) Figure 11 The tool at point ) applies a manipulating force 19 to the second element 4.

[0144] By applying a manipulating force 19 acting on the operating element 18 of the first element 4 and in the direction of rotation 17 of the swing, the second element 4 can be swung from the second position to the first position. Through this manipulating force 19, the protrusions 14 and 15 can elastically deform to release the force-locking of the stop mechanism 5, and can then (re)move away from each other in an opening movement 16. Here, the surface of the second element 4 that interacts with the stop elements 12 and 13 or the protrusions 14 and 15 can be designed as an inclined plane, so that the protrusions 14 and 15 further open as the swing of the second element 4 relative to the first element 3 increases.

[0145] However, it is preferable that the stop elements 12 and 13 form the stop mechanism 5 only when swinging toward the second position, and thus do not prevent the swing back to the first position. This, for example, enables the cover 2 to be released from the fastening element 1 by (only) overcoming the elastic action of the energy storage element 6.

[0146] By means of the proposed fastening element 1, it is possible to securely and repeatedly loosen the cover 2 to the fastening plate 21 (e.g., the junction box), wherein the fastening element 1, which is exactly the fastener of the cover 2, remains invisible to the user of the bathroom fixture.

Figure 14The second element 4 of the fastening element 1 according to the second embodiment variant is shown in a perspective view. Figure 15 The third element 32 of the fastening element 1 according to the second embodiment variant is shown in a perspective view. Figure 16 The energy storage element 6, designed as a spring element, is shown in a perspective view of the fastening element 1 according to the second embodiment variant. Figure 17 The fastening element 1 (in the second position) according to the second embodiment variant is shown in a perspective view. Figure 18 A perspective sectional view shows the situation in the first position according to... Figure 17 Fastening element 1. Figure 19 Another perspective sectional view shows the results based on Figure 17 and Figure 18 Fastening element 1 (in the second position). Figure 20 A fastening device 20 having a fastening element 1 according to a second embodiment variant is shown in a perspective view, wherein the fastening element 1 is in a first position. Figure 21 It shows that according to Figure 20 The fastening device 20, wherein the fastening element 1 is in an intermediate position between the first and second positions. Figure 22 It shows that according to Figure 20 and Figure 21 The fastening device 20, wherein the fastening element 1 is in the second position. The following describes the fastening device 20 together. Figures 13 to 22 Reference Figures 1 to 12 Detailed explanation.

[0148] According to the second embodiment variant (corresponding to the second design), the fastening element 1 for the cover 2 has a first element 3, which can be in a first position (see...) Figure 17 ) and second position (see Figure 19 The second element 4, which is arranged at the first element 3 in a swaying manner, the third element 32, which is arranged at the first element 3 and can move (only) relative to the first element 3, and the energy storage element 6 designed as a spring element.

[0149] In the fastening element 1 according to the second embodiment variant, the third element 32, which moves through the protrusion 22 of the cover 2, contacts the second element 4 (see...). Figure 20 And cause the second element 4 to swing from the first position to the second position (see...). Figure 21 and Figure 22 Here, the sliding motion between the stop mechanism 5 and the first pin 7 is first overcome when the stop mechanism 5 ( Figure 18 and Figure 19 ).

[0150] The third element 32 is arranged at the first element 3 in a non-discardable manner, and can only move in one direction. This mobility is achieved by the second pin 34 at the third element 32 and the second guide rail 35 at the first element 3.

[0151] In the fastening element 1 according to the second embodiment, the second element 4 has two first pins 7, and the third element 3 has two elongated first guide rails 33, wherein each first pin 7 extends into a corresponding first guide rail 33. To manufacture the fastening element 1, the first element 3 is designed as a two-piece unit, wherein the second element 4, the third element 32, and the spring element 6 are arranged between the two halves of the first element 3.

[0152] The first pin 7 is arranged in the first guide rail 33, thereby forming a rotation axis 11 for the swinging of the second element 4. Upon swinging to the second position, the locking mechanism of the second element 4 present in the first position (and caused by the first element 3) is first released. This locking is achieved through the interaction between the correspondingly shaped first guide rail 33 and the stop mechanism 5 (another first pin at the second element 4) (see...). Figure 20 and Figure 22 When the second element 4 swings about the first pin 7 (in the direction of rotation 17), the second element 4 and consequently the first pin 7 also move, thereby at least partially reducing the spring force of the higher spring element 6 present in the first position.

[0153] The third element 32 prevents the device from swinging back to the first position from the second position. In the second position, the third element is arranged to have moved relative to the first position and contact the second element 4. Here, the third element 32 is locked in the moved position by the protrusion 22 of the cover 2 (see...). Figure 22 ).

[0154] To swing back to the first position, the second element 4 needs to be manipulated by a manipulating force (i.e., moved first and then swung), thereby overcoming the preload and moving the third element 32. The first pin 7 is guided in the first guide rail by the shape of the first guide rail 33, which is preset to the movement of the second element 4 during its swing back.

[0155] In the fastening element 1 according to the second embodiment, the second element 4 is contacted by the third element 32 (moved by the protrusion 22), causing the second element 4 to swing from the first position and move to the second position. Here, the spring force of the spring element 6 increases firstly due to this swing. This is ensured by the position of the spring element 6 and its point of action at the first element 3 and the second element 4 (see...). Figure 18 and Figure 19 ).

[0156] If the third element is moved by 32, the third element contacts the second element 4 and causes the second element 4 to swing, wherein the spring element 6 is arranged between the first element 3 and the second element 4 such that the second element 4 swings against the elastic action of the spring element 6.

[0157] The second element 4 is locked in the first position by the first element 3 (and the stop mechanism 5) and in the second position by the third element 32.

[0158] exist Figures 20 to 22 The fastening device 20 for cover 2 shown includes a fastening plate 21 (not shown, see [link]). Figure 1 and Figure 8 The cover 2 and a plurality of fastening elements 1, as described (not shown), according to a second embodiment variant, for fastening the cover 2 to the fastening plate 21. The fastening elements 1 are fastened to the fastening plate 21 by means of a first element 3 (e.g., by riveting or screw connection). The cover 2 has a protrusion 22 that, during the installation of the cover 2, contacts and moves a third element 32, thereby causing the third element 32 to contact a second element 4 and swing the second element to a second position, wherein, in the second position, the second element 4 establishes a connection with the protrusion 22 to fasten the cover 2 to the fastening plate 21. Figure 22 ).

[0159] A connection is established with the protrusion 22 via a locking hook, wherein the second element 4 forms a locking connection with the window 31 in the protrusion 22 relative to the mounting direction 27 (see [link]). Figure 22 Here, the third element 32 works in conjunction with the protrusion 22 such that after the second element 4 swings, the cover 2 continues to move toward the fastening plate 21 along the mounting direction 27 during the lifting movement 29 until the locking hook connection is established.

Figure 24 The second element 4 of the fastening element 1 according to the third embodiment variant is shown in a perspective view. Figure 25 The third element 32 of the fastening element 1 according to the third embodiment variant is shown in a perspective view. Figure 26 The energy storage element 6, designed as a spring element, is shown in a three-dimensional view of the fastening element 1 according to the third embodiment variant. Figure 27 The fastening element 1 (in the second position) according to the third embodiment variant is shown in a perspective view. Figure 28 A perspective sectional view shows the situation in the first position according to... Figure 27 Fastening element 1. Figure 29 Another perspective sectional view shows the results based on Figure 27 and Figure 28Fastening element 1 (in the second position). Figure 30 A fastening device 20 having a fastening element 1 according to a third embodiment variant is shown in a perspective view, wherein the fastening element 1 is in a first position. Figure 31 It shows that according to Figure 30 The fastening device 20, wherein the fastening element 1 is in an intermediate position between the first and second positions. Figure 32 It shows that according to Figure 30 and Figure 31 The fastening device 20, wherein the fastening element 1 is in the second position. The following describes the fastening device 20 together. Figures 23 to 32 Reference Figures 1 to 12 and Figures 13 to 22 Detailed explanation.

[0161] According to the third embodiment variant (corresponding to the third design), the fastening element 1 for the cover 2 has a first element 3, which can be in a first position (see...) Figure 28 ) and second position (see Figure 29 The second element 4, which is arranged at the first element 3 in a swaying manner, the third element 32, which is arranged at the first element 3 and can move relative to the first element 3, and the energy storage element 6, which is designed as a spring element.

[0162] If the second element 4 is swung, the second element contacts the third element 32 and moves it, wherein the spring element 6 is arranged between the first element 3 and the third element 32 such that the third element 32 moves against the elastic action of the spring element 6.

[0163] The second element 4 is locked in the first and second positions by the third element 32.

[0164] In the fastening element 1 according to the third embodiment, the second element 4 has two first pins 7 arranged coaxially with each other, and the first element 3 has a correspondingly shaped recess 10, wherein each first pin 7 extends into the corresponding recess 10 and forms a rotation axis 11. To manufacture the fastening element 1, the first element 3 is designed as a two-piece unit, wherein the second element 4, the third element 32, and the spring element are arranged in an irreplaceable manner between the two halves of the first element 3.

[0165] The first pin 7 is arranged in the corresponding recess 10, thereby forming a rotation axis 11 for the second element 4 to swing relative to the first element 3. When swinging to the second position, the locking of the second element 4 present in the first position and caused by the third element 32 is first released.

[0166] The second element 4 has circumferential surfaces 36 that extend at an angle to each other, which contact the preloaded third element 32. When the second element 4 oscillates, it oscillates relative to the first element 3 and the third element 32 along the rotation direction 7. Here, the elasticity of the spring element 6 overcomes the elasticity of the third element 32, causing it to shift, and the contact between the second element 4 and the third element 32 shifts to the (other inclined) circumferential surface 36 that is closest in the rotation direction 17.

[0167] The third element 32 prevents the swinging back from the second position to the first position, and the third element contacts the second element 4 arranged in the second position via the circumferential surface 36.

[0168] In order to swing back, the second element 4 needs to be manipulated by a manipulation force (i.e., rotated in the direction of rotation 17), so that the preload and the elastic effect of the spring element 6 can be overcome to move the third element 3.

[0169] exist Figures 30 to 32 The fastening device 20 for cover 2 shown includes a fastening plate 21 (not shown, see [link]). Figure 1 and Figure 8 The cover 2 and a plurality of fastening elements 1, described in a third embodiment variant (not shown), for fastening the cover 2 to the fastening plate 21. The fastening elements 1 are fastened to the fastening plate 21 by means of a first element 3 (e.g., by riveting or screw connection). The cover 2 has a protrusion 22 that, during the installation of the cover 2, contacts a second element 4 and causes it to swing. During the swinging of the second element 4, the second element contacts a third element 32 and causes it to move, wherein a spring element is arranged between the first element 3 and the third element 32 such that the movement of the third element 32 overcomes the elastic action of the spring element 6. In the second position, the second element 4 establishes a connection with the protrusion 22 to fasten the cover 2 to the fastening plate 21. Figure 32 ).

[0170] A connection is established with the protrusion 22 via a locking hook, wherein the second element 4 forms a locking connection with the window 31 in the protrusion 22 relative to the mounting direction 27 (see [link]). Figure 32 Here, the second element 4 works in conjunction with the protrusion 22 such that as the swing of the second element 4 increases, the cover 2 continues to move toward the fastening plate 21 along the mounting direction 27 during the lifting movement 29.
