Description

Technical Field

[0001] The invention relates to a plurality of different designs of fastening elements for covers, in particular for fastening elements in sanitary installations, wherein the sanitary installations can be used by a person, in particular in a toilet, such as, for example, a bathroom, for showering, bathing and / or body cleaning. Background Art

[0002] In bathroom equipment (such as, for example, shower devices or bathtubs), large ceiling-embedded showers (also called built-in showers) with covers (Cover, also referred to as covers below) can be used. As the only visible part of the ceiling shower, the cover, on the one hand, conceals the shower components and the dark box located in the ceiling of the room, and on the other hand, must meet high aesthetic requirements, because this type of shower is usually a high-priced product in the high-end market. Therefore, the visible fastening elements for the cover cause unacceptable appearance interference. Since the shower components arranged behind it or covered by it must be accessible, permanent fixing of the cover is not allowed. In addition, due to the challenges in manufacturing technology, the cover needs to be made of a material with sufficiently stable shape (such as, for example, metal), for example, by means of a zinc die-casting method. Therefore, due to the large weight, it is very important to fix the cover firmly and stably enough.

[0003] Fastening to water-conducting functional components is likewise not possible, since the stability of the connection is impaired due to certain water flow dynamics.

[0004] Therefore, the following conditions must be met when fixing a heavy cover (e.g. more than 500 grams) to a cassette or fastening plate (which may be difficult to reach, for example because it is arranged on the ceiling):

[0005] Securely fastened (i.e. cannot loosen on its own);

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

[0007] Easy to install; and

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

[0009] Known solutions for invisible connections are, for example, magnets, clips or latch hooks, but due to the large gravity, their mechanical properties are insufficient. Other known connections, such as screw connections (front, side), are not advisable in principle because they are visible and therefore conflict with aesthetic requirements. Summary of the invention

[0010] The object of the present invention is therefore, at least in part, to solve the problems set out with reference to the prior art, and in particular to provide a fastening element for a cover, which can in particular be used in sanitary equipment and preferably for fastening a cover at a ceiling - recessed shower.

[0011] This object is achieved by a fastening element having the features according to independent claims 1, 9 and 12. Further advantageous embodiments of the invention are given in the dependent claims. It should be noted that the features listed separately in the dependent claims can be combined with each other in any technically reasonable way and define further embodiments of the invention. In addition, the features given in the claims are explained and illustrated in more detail in the description, in which further preferred embodiments of the invention are shown.

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

[0013] The fastening element and the cover can in particular be used in sanitary equipment and are preferably suitable for a ceiling - recessed shower.

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

[0015] - a first element; and

[0016] - a second element arranged at the first element in a manner such 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 pre - loaded by a stop mechanism of the first element, wherein the stop mechanism can be cancelled by elastic deformation of the first element, and the second element can swing towards the second position by at least partially reducing the pre - load.

[0018] The stop mechanism in particular prevents swinging from the first position to the second position in a form - fitting manner. In particular, the stop mechanism (i.e., the locking action of the stop mechanism preventing the second element from swinging towards the second position) cannot be cancelled by a force acting in the swinging direction (at least as long as the first element does not undergo plastic deformation).

[0019] In particular, the fastening element (according to the first embodiment) has at least one energy - storage element for generating the pre - load. The energy - storage element can for example be a force spring, a compression spring, a helical spring, a pneumatic energy - storage device, or other elements that can be elastically deformed and at the same time store deformation energy.

[0020] In particular, one of the components has at least one first pin, and the other of the components has a receiving portion for the first pin. To manufacture the fastening element, the second component can be pushed into the recess of the first component in a first direction until at least one first pin is arranged in the receiving portion and thereby a rotational axis for the swinging of the second component is formed.

[0021] In particular, by this pushing, one of the components can be elastically deformed so that at least one first pin is latched in the receiving portion.

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

[0023] In particular, the stop mechanism is constituted by two stop elements, wherein each stop element is arranged at a protrusion of the first component. To cancel the stop mechanism, the protrusion can be elastically deformed and can move away from each other in an opening movement.

[0024] In particular, the rotational direction of the swinging extends perpendicular to the direction of the opening movement of the protrusion. In particular, the rotational axis extends substantially parallel to the direction of the opening movement.

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

[0026] In particular, the stop mechanism at least prevents the second component from swinging back from the second position to the first position in a force-locking manner. Thus, in particular, the force-locking lock of the stop mechanism can be overcome by a actuating force acting in the swinging direction, wherein at least partial plastic deformation of one of the components does not occur here.

[0027] In particular, the second component can be swung from the second position to the first position by applying an actuating force acting at the actuating element of the second component and acting in the rotational direction of the swinging. In particular, by this actuating force, the protrusion is elastically deformed (if necessary to cancel the force-locking lock of the stop mechanism), and moves away from each other in an opening movement here. Here, the surface of the second component that interacts with the stop element or the protrusion can be designed as an inclined plane, for example, so that the protrusion is further opened as the swinging of the second component relative to the first component increases.

[0028] However, it is preferably that the stop element forms the stop mechanism only when swinging towards the second position and thus does not impede the swing back to the first position. Thereby, for example, it is achieved that the cover is loosened from the fastening element by (only) overcoming the elastic action of the energy storage element.

[0029] Furthermore, a fastening device for a cover is proposed. The fastening device at least has:

[0030] - a fastening plate;

[0031] - a cover; and

[0032] - at least one of the fastening elements (according to the first design) for fastening the cover at the fastening plate.

[0033] The fastening element (according to the first design) is fastened at the fastening plate by a first element (e.g., by riveting or screwing). The cover has (at least one) protrusion which elastically deforms the first element during the installation of the cover and thereby cancels the stop mechanism, so that a second element arranged in a preloaded manner in a first position swings relative to the first element and a connection with the protrusion is established for fastening the cover at the fastening plate.

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

[0035] - a first element;

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

[0037] - a third element arranged 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 swing, wherein the spring element is arranged between the first element and the second element such that the second element swings against the elastic action of the spring element.

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

[0041] Furthermore, another fastening device for a cover is proposed. The fastening device at least has:

[0042] - a fastening plate;

[0043] - a cover; and

[0044] - at least one of the fastening elements (according to the second design) for fastening the cover at the fastening plate.

[0045] The fastening element (according to the second design) is fastened to the fastening plate by the first element (e.g., by riveting or screwing). The cover has (at least one) projection which, during the installation of the cover, contacts the third element and causes the third element to move, so that the third element contacts the first element and causes the first element to swing into the second position, in which the second element establishes a connection with the projection for fastening the cover to the fastening plate.

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

[0047] - a first element;

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

[0049] - a third element arranged at the first element and capable of (only) moving relative to the first element; 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, where the spring element is arranged between the first element and the third element such that the movement of the third element takes place against the elastic action of the spring element.

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

[0053] Furthermore, another fastening device for a cover is proposed. The fastening device has at least:

[0054] - a fastening plate;

[0055] - a cover; and

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

[0057] The fastening element (according to the third design) is fastened to the fastening plate by the first element (e.g., by riveting or screwing). The cover has (at least one) projection which, during the installation of the cover, contacts the second element and causes the second element to swing into the second position, in which the second element establishes a connection with the projection for fastening the cover to the fastening plate.

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

[0059] The discharging device is connected to a water-conducting supply line, for example, so that water can be output to the user of the sanitary equipment via the discharging device and through the cover. In particular, the discharging device has a plurality of outlets through which water can flow out of the discharging device. In particular, each outlet of the discharging device is associated with an opening in the cover, so that water can be output from the discharging 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 (according to the first and / or second and / or third design) are arranged between the two planes, and the cover can be displaced along an installation direction extending transversely to the plane. Here, the protrusions can be connected to the fastening elements respectively.

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

[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 perform an opening movement (during the displacement of the cover along the installation direction). Thereby, the locking function of the stop mechanism is cancelled and the second element swings from the first position to the second position. In particular, the second element cooperates with the protrusion so that a form-locking connection is established between the cover and the fastening element with respect to the installation direction.

[0063] In particular, the second element of the fastening element according to the first design cooperates with the protrusion such that as the swing of the second element increases, the cover continues to be displaced 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 resumes its shape to such an extent that the stop element forms a force-locking stop mechanism that prevents swinging back to the first position.

[0065] For swinging back, in particular, the second element needs to be manipulated by a manipulation force so that the force-locking lock of the stop mechanism can be overcome.

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

[0067] Here, in particular, first, the spring force of the spring element is increased due to the swing. This is ensured by the position of the spring element and its points of action on the first element and the second element.

[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 cooperating with the stop mechanism); thus, the spring force of the spring element is not increased just during this time.

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

[0070] The at least one first pin is arranged in the first guide track and thus forms a rotational axis for the swinging of the second element.

[0071] The third element is in particular arranged at the first element in a non-lost manner and is only movable in one direction here. This mobility is achieved by a second pin at the third element and a second guide track at the first element, the second pin engaging into the second guide track and being guided by the second guide track.

[0072] In particular, when swinging into the second position, first the latching of the second element present in the first position (and caused by the first element) is released. In particular, when the second element swings (in the rotational direction) about the first pin, a movement of the first pin also occurs, wherein thereby at least partially the spring force of the higher spring element present in the first position is reduced.

[0073] Swinging back to the first position is prevented by the third element, in the second position, the third element being arranged to have moved and contacting the second element.

[0074] For swinging back, in particular, it is necessary to manipulate the second element by a manipulation force (i.e., first move it and then swing it), so that the preloading can be overcome and the third element can be moved.

[0075] In the fastening element according to the second design, in particular, the third element (moved by the projection) contacts the second element and swings the second element from the first position to the second position.

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

[0077] The at least one first pin is arranged in the receiving part and thus forms a rotational axis for the pivoting of the second element.

[0078] In particular, when pivoting into the second position, first the latching of the second element present in the first position (and caused by the third element) is released.

[0079] In particular, the second element has a circumferential surface extending at an angle to one another, which is contacted by the preloaded third element. When the second element pivots, the second element pivots relative to the first element and the third element along the direction of rotation. Here, the third element is displaced against the elastic action of the spring element, and the contact between the second element and the third element is displaced to the circumferential surface closest in the direction of rotation (another inclined one).

[0080] The third element prevents pivoting back from the second position into the first position, and the third element contacts the second element arranged in the second position by means of the circumferential surface.

[0081] For pivoting back, in particular, it is necessary to manipulate the second element by means of a manipulation force (i.e., simply rotate in the direction of rotation), so that the preload can be overcome and the third element can be moved against the elastic action of the spring element.

[0082] A sanitary device is in particular a device for personal hygiene. For this purpose, the sanitary device can for example be configured in the form of a shower device or a bathtub and / or be arranged in a bathroom (such as a bathroom). In addition, the sanitary device can be used for therapeutic purposes. The sanitary device has at least one discharge device for a liquid. The at least one delivery device can in particular be a showerhead, an overhead shower, a ceiling - recessed shower, a nozzle, and / or a water outlet. Through at least one outlet of the discharge device, a liquid, in particular water, can be output into the (at least one) basin (collection device) of the sanitary device.

[0083] The basin or collection device can in particular be configured in the form of a shower tray or a bathtub. In addition, the basin can in particular be arranged or fastened in a position - fixed manner, for example, on the building floor. In particular, the basin has a discharge opening for the liquid. Through this discharge opening, the liquid can in particular be conveyed to the public sewer system.

[0084] In addition, the sanitary equipment especially includes a thermostat (in the simplest embodiment, a mixing device without its own temperature control), through which hot water and cold water can be mixed into temperature-regulated water. The hot water and cold water are respectively fresh water, and can be mixed into mixed water with a desired temperature through the thermostat. The hot water temperature of the hot water can especially be up to 90 °C (Celsius), preferably 25 °C to 90 °C, particularly preferably 55 °C to 65 °C, and / or the cold water temperature of the cold water can especially be up to 25 °C (Celsius), 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, the hot water can be conveyed to the thermostat via a hot water pipe from a hot water source (such as a boiler, (private and / or local) solar thermal system or heat pump), and / or the cold water can be conveyed to the thermostat via a cold water pipe from a cold water source (such as a building water supply connection, a public water supply network or (private and / or local) well). The hot water pipe and / or the cold water pipe can be at least partially configured in the form of a pipe. In addition, the hot water pipe and / or the cold water pipe can at least partially extend through a building wall and / or a building floor. The thermostat can have a hot water inlet for the hot water and / or a cold water inlet for the cold water. The hot water pipe can be connected to the hot water inlet and / or the cold water pipe can be connected to the cold water inlet. In addition, the thermostat can be at least partially arranged in a building wall or a building floor.

[0086] The mixing water pipe can be at least partially configured in the form of a pipe and / or a hose and is fluid-technically connected to the discharge device.

[0087] The desired temperature of the liquid output through the discharge device can be adjusted by the user of the sanitary equipment, for example, through an operating element of the sanitary equipment and / or the thermostat.

[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 The cover 2 is shown in a three-dimensional view. Figure 4 The second element 4 of the fastening element 1 according to the first implementation variant is shown in a three-dimensional view. Figure 5 The first element 3 of the fastening element 1 according to the first implementation variant is shown in a three-dimensional view. Figure 6 Two energy storage elements 6 of the fastening element 1 according to the first implementation variant are shown in a three-dimensional view. Figure 7 The fastening element 1 according to the first implementation variant is shown in a three-dimensional view. Figure 8 The fastening device 20 is shown in a top view. The following is a joint description Figures 1 to 8 .

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

[0125] The fastening element 1 according to the first implementation variant (corresponding to the first design) includes a first element 3 and a second element 4 arranged at the first element 3 in such a way that it can swing at least between a first position (see Figure 9 and Figure 10 ) and a second position (see Figure 11 and Figure 12 ).

[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 cancelled by the elastic deformation of the first element 3, and the second element 4 can swing towards the second position by at least partially reducing the preload.

[0127] The stop mechanism 5 prevents the swing from the first position to the second position in a form - locking manner. The stop mechanism 5 cannot be cancelled by a force acting in the swing direction (e.g., the actuating force 19), that is, the locking effect of the stop mechanism 5 preventing the second element 4 from swinging towards the second position cannot be cancelled. At least if the first element 3 does not undergo plastic deformation, it is impossible to cancel the locking effect.

[0128] The fastening element 1 has two springs as energy - storage elements 6 for generating the 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. For manufacturing the fastening element 1, the second element 4 can be pushed into the notch 10 of the first element 3 along the first direction 9 (see for example Figure 5 , 7 and 9) until the first pins 7 are arranged in the corresponding receiving portions 8 and thereby form a rotational axis 11 for the swing of the second element 4.

[0130] By this pushing, the first element 3 can be at least partially elastically deformed so that the first pins 7 can be latched in the corresponding notches 8.

[0131] The stop mechanism 5 is constituted by two stop elements 12, 13, wherein each stop element 12, 13 is arranged at the protrusions 14, 15 of the first element 3. For cancelling the stop mechanism 5, the protrusions can be elastically deformed and at the same time move away from each other in an opening movement 16 (see Figure 12 ).

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

[0133] The stop mechanism 5 locks the second element 4 against swinging back from the second position to the first position at least (only) in a form - fit manner. That is, in particular, the form - fit locking of the stop mechanism 5 can be overcome by an actuating force 19 acting in the direction of swinging, where at least partial plastic deformation of one of the elements 3, 4 does not occur (see the following description of Figure 11 and Figure 12 ).

[0134] By applying an actuating force 19 acting on the actuating element 18 of the second element 4 and acting in the rotational direction of swinging 17 (see Figure 7 ), the second element 4 can be swung from the second position to the first position. By this actuating force 19, the projections 14, 15 can be elastically deformed to cancel the form - fit locking of the stop mechanism 5, and can move away from each other in an opening movement 16. Here, the surfaces of the second element 4 that cooperate with the stop elements 12, 13 or the projections 14, 15 can be designed, for example, as inclined planes, so that the projections 14, 15 open further as the swinging of the second element 4 relative to the first element 3 increases.

[0135] The fastening element 1 is fastened to the fastening plate 21 by the first element 3 (for example, by riveting or screwing). The cover 2 has a plurality of raised portions 22, which elastically deform the corresponding first element 3 (specifically, its projections 14, 15) during the installation process of the cover 2, and thereby cancel the stop mechanism 5, so that the second element 4 arranged in the first position in a pre - loaded manner swings relative to the first element 3, and a connection with the raised portions 22 is established to fasten the cover 2 to the fastening plate 21.

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

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

[0138] The fastening plate 21 extends in a first plane 25, and the cover 2 extends in a second plane 26. A plurality of fastening elements 1 are arranged between the planes 25, 26. The cover 2 is displaceable along an installation direction 27 extending transversely to the planes 25, 26. Herein, the raised portions 22 can be respectively connected to the fastening elements 1 (this also applies to the second and third implementation variants). Herein, each raised portion 22 is respectively associated with one fastening element 1.

[0139] Figure 9 The details of the fastening device 20 according to Figure 8 are shown in a side view, wherein the fastening element 1 is in the first position. Figure 10 The details according to Figure 9 are shown in a perspective view. Figure 11 The details of the fastening device 20 according to Figure 8 are shown in a side view, wherein the fastening element 1 is in the second position. Figure 12 The details according to Figure 12 are shown in a perspective view. The following is a common description Figures 9 to 12 . Refer to the detailed description of Figures 1 to 8 .

[0140] Figure 9 and 10 show the fastening device 20 before the connection between the raised portion 22 and the fastening element 1 is established. The fastening element 1 according to the first implementation variant is fastened to the fastening plate 21 by a first element 3 (for example, by riveting or screw connection, not shown). The cover 2 has raised portions 22, which elastically deform the corresponding first element 3 (specifically, its protrusions 14, 15) during the installation process of the cover 2, so that the protrusions move away from each other during the opening movement 16. Due to the opening movement 16 pushed by the side edges of the raised portions 22, the stop elements 12, 13 also move away from each other during the opening movement 16, so that the stop mechanism 5 is cancelled. Thus, the second element 4 pre-loaded by the energy storage element 6 in the first position can swing relative to the first element 3, and a connection with the raised portion 22 is established to fasten the cover 2 to the fastening plate 21. The connection with the raised portion 22 is established by a snap hook connection, in which the second element 4 forms a form-locking connection with the window 31 in the raised portion 22 relative to the installation direction 27 (see Figure 12 ). Herein, the second element 4 interacts with the raised portion 22 such that as the swing of the second element 4 increases, the cover 2 continues to displace along the installation direction 27 towards the fastening plate 21 during the lifting movement 29.

[0141] In Figure 11 and Figure 12Shown is the fastening device 20 after establishing a connection between the projection 22 and the fastening element 1 according to the first variant of the embodiment. The connection to the projection 22 is established by means of a snap hook connection, in which the second element 4 and the window 31 in the projection 22 form a form-fitting connection with respect to the installation direction 27.

[0142] When the stop elements 12, 13 re-form the stop mechanism 5, the elastic restoring projections 14, 15 can prevent swinging back towards the first position here. For this purpose, the second element 4 can be shaped accordingly, so that the projections 14, 15 can swing back to such an extent that the stop elements 12, 13 form a stop mechanism 5 for the second element 4 to prevent the second element from swinging towards the first position in the rotational direction 17.

[0143] The stop mechanism 5 then prevents the second element 4 from swinging back from the second position into the first position at least in a force-fitting manner. Here, only a sufficiently high actuating force 19 acting in the swinging direction can overcome the force-fitting locking of the stop mechanism 5, where no at least partial plastic deformation of one of the elements 3, 4 occurs. For example, the actuating force 19 is applied to the second element 4 by means of a tool acting on the actuating element 18 (see Figure 11 ).

[0144] By applying an actuating force 19 acting at the actuating element 18 of the first element 4 and acting in the rotational direction 17 of the swing, the second element 4 can be swung from the second position into the first position, where by means of this actuating force 19, the projections 14, 15 can be elastically deformed to cancel the force-fitting locking of the stop mechanism 5, and here they can 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, 13 or the projections 14, 15 can be designed as an inclined plane, so that the projections 14, 15 open further as the swing of the second element 4 relative to the first element 3 increases.

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

[0146] With the proposed fastening element 1, it is possible to firmly and repeatedly releasably fasten the cover 2 to a fastening plate 21 (such as a cassette), where the fastening element 1, which is just the fastener for the cover 2, remains invisible to the user of the sanitary equipment.

[0147] Figure 13 Shown is the first element 3 of the fastening element 1 according to the second variant of the embodiment. Figure 14The second element 4 of the fastening element 1 according to the second implementation variant is shown in a three-dimensional view. Figure 15 The third element 32 of the fastening element 1 according to the second implementation variant is shown in a three-dimensional view. Figure 16 The energy storage element 6 designed as a spring element of the fastening element 1 according to the second implementation variant is shown in a three-dimensional view. Figure 17 The fastening element 1 according to the second implementation variant (in the second position) is shown in a three-dimensional view. Figure 18 A three-dimensional sectional view shows the fastening element 1 according to Figure 17 in the first position. Figure 19 Another three-dimensional sectional view shows the fastening element 1 according to Figure 17 and Figure 18 in the second position. Figure 20 The fastening device 20 with the fastening element 1 according to the second implementation variant is shown in a three-dimensional view, wherein the fastening element 1 is in the first position. Figure 21 The fastening device 20 according to Figure 20 is shown, wherein the fastening element 1 is in an intermediate position between the first and second positions. Figure 22 The fastening device 20 according to Figure 20 and Figure 21 is shown, wherein the fastening element 1 is in the second position. The following is described together Figures 13 to 22 . Refer to the detailed description of Figures 1 to 12 .

[0148] The fastening element 1 for the cover 2 according to the second implementation variant (corresponding to the second design) has a first element 3, a second element 4 arranged to swing between a first position (see Figure 17 ) and a second position (see Figure 19 ) at the first element 3, a third element 32 arranged at the first element 3 and movable relative to the first element 3 (only), and an energy storage element 6 designed as a spring element.

[0149] In the fastening element 1 according to the second implementation variant, the third element 32 moved by the projection 22 of the cover 2 contacts the second element 4 (see Figure 20 ), and causes the second element 4 to swing from the first position to the second position (see Figure 21 and Figure 22 ). Here, first, when sliding between the stop mechanism 5 and the first pin 7, the stop mechanism 5 is overcome ( Figure 18 and Figure 19 ).

[0150] The third element 32 is arranged at the first element 3 in a non-loseable manner and is only movable in one direction here. This movability is achieved by a second pin 34 at the third element 32 and a second guide track 35 at the first element 3.

[0151] In the fastening element 1 according to the second embodiment variant, the second element 4 has two first pins 7, and the third element 3 has two elongated first guide tracks 33, where each first pin 7 extends into a corresponding first guide track 33. For manufacturing the fastening element 1, the first element 3 is designed in two parts, where 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 pins 7 are arranged in the first guide tracks 33 and thereby form a rotational axis 11 for the pivoting of the second element 4. When pivoting into the second position, first the latching of the second element 4 present in the first position (and caused by the first element 3) is released. This latching is achieved by the interaction between the correspondingly shaped first guide tracks 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 pivots about the first pins 7 (in the rotational direction 17), the second element 4 and thus also the first pins 7 are displaced, whereupon the spring force of the higher spring element 6 present in the first position is at least partially reduced.

[0153] Pivoting back into the first position is prevented by the third element 32. In the second position, the third element is arranged displaced relative to the first position and contacts the second element 4. Here, the third element 32 is latched in this displaced position by the projection 22 of the cover 2 (see Figure 22 ).

[0154] For pivoting back into the first position, the second element 4 needs to be manipulated by a manipulation force (i.e., first displaced and then pivoted), so that the preload can be overcome and the third element 32 can be displaced. The shape of the first guide tracks 33 presets the movement of the second element 4 during the pivoting back of the second element 4, and the first pins 7 are guided in this first guide track.

[0155] In the fastening element 1 according to the second embodiment variant, the third element 32 (displaced by the projection 22) contacts the second element 4 and pivots and displaces the second element 4 from the first position into the second position. Here, first the spring force of the spring element 6 is increased due to this pivoting. This is ensured by the position of the spring element 6 and its points 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 a spring element 6 is arranged between the first element 3 and the second element 4 such that the swing of the second element 4 occurs against the elastic action of the spring element 6.

[0157] The second element 4 is latched 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] In Figures 20 to 22 The fastening device 20 for the cover 2 shown in includes a fastening plate 21 (not shown, see Figure 1 and Figure 8 ), the cover 2, and a plurality of fastening elements 1 (not shown) described for fastening the cover 2 to the fastening plate 21 according to the second embodiment variant. The fastening element 1 is fastened to the fastening plate 21 by the first element 3 (for example by riveting or screw connection). The cover 2 has a projection 22 which, during the installation of the cover 2, contacts the third element 32 and causes it to move, so that the third element 32 contacts the second element 4 and causes the second element to swing into the second position, wherein in the second position, the second element 4 establishes a connection with the projection 22 for fastening the cover 2 to the fastening plate 21 ( Figure 22 ).

[0159] The connection with the projection 22 is established by a snap hook connection, in which the second element 4 and a window 31 in the projection 22 form a form-locking connection with respect to the installation direction 27 (see Figure 22 ). Here, the third element 32 interacts with the projection 22 such that after the second element 4 has swung, the cover 2 continues to shift in the installation direction 27 towards the fastening plate 21 during the lifting movement 29 until the snap hook connection is established.

[0160] Figure 23 The first element 3 of the fastening element 1 according to the third embodiment variant is shown. 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 of the fastening element 1 according to the third embodiment variant is shown in a perspective view. Figure 27 The fastening element 1 according to the third embodiment variant (in the second position) is shown in a perspective view. Figure 28 A fastening element 1 in the first position is shown in a perspective sectional view according to Figure 27 . Figure 29 Another perspective sectional view shows the fastening element 1 according to Figure 27 and Figure 28the fastening element 1 (in the second position). Figure 30 The fastening device 20 with the fastening element 1 according to the third exemplary embodiment is shown in a perspective view, where the fastening element 1 is in the first position. Figure 31 The following shows a fastening device 20 according to Figure 30 where the fastening element 1 is in an intermediate position between the first and second positions. Figure 32 The following shows a fastening device 20 according to Figure 30 and Figure 31 where the fastening element 1 is in the second position. The following is a joint description of Figures 23 to 32 . Refer to the detailed description of Figures 1 to 12 and Figures 13 to 22 .

[0161] The fastening element 1 for the cover 2 according to the third exemplary embodiment (corresponding to the third design) has a first element 3, a second element 4 arranged at the first element 3 so as to be pivotable between a first position (see Figure 28 ) and a second position (see Figure 29 ), a third element 32 arranged at the first element 3 and movable relative to the first element 3, and an energy storage element 6 designed as a spring element.

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

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

[0164] In the fastening element 1 according to the third exemplary embodiment, the second element 4 has two first pins 7 arranged coaxially with each other, and the first element 3 has correspondingly shaped recesses 10, where each first pin 7 extends into a corresponding recess 10 and forms a rotation axis 11. For the production of the fastening element 1, the first element 3 is designed as a two-piece part, where the second element 4 and the third element 32 as well as the spring element are arranged in a non-losing manner between the two halves of the first element 3.

[0165] The first pins 7 are arranged in the corresponding recesses 10 and thereby form a rotation axis 11 for the pivoting of the second element 4 relative to the first element 3. When pivoting into the second position, first the latching of the second element 4 present in the first position and caused by the third element 32 is released.

[0166] The second element 4 has a peripheral surface 36 that extends at an angle to each other and is contacted by a preloaded third element 32. When the second element 4 swings, the second element 4 swings relative to the first element 3 and the third element 32 along the rotational direction 7. Here, the third element 32 is displaced against the elastic action of the spring element 6, and the contact between the second element 4 and the third element 32 is displaced to the (another inclined) peripheral surface 36 closest in the rotational direction 17.

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

[0168] For the swing-back, it is necessary to manipulate the second element 4 (i.e., rotate along the rotational direction 17) by a manipulation force, so that the preload can be overcome and the third element 3 can be displaced against the elastic action of the spring element 6.

[0169] In Figures 30 to 32 The fastening device 20 for the cover 2 shown in Figure 1 and Figure 8 ) includes a fastening plate 21 (not shown, see Figure 32 ), the cover 2, and a plurality of described (not shown) fastening elements 1 according to the third implementation variant for fastening the cover 2 to the fastening plate 21. The fastening element 1 is fastened to the fastening plate 21 by the first element 3 (e.g., by riveting or screw connection). The cover 2 has a protrusion 22, which contacts the second element 4 and causes it to swing during the installation process of the cover 2. During the swing of the second element 4, the second element contacts the third element 32 and causes it to move, wherein the spring element is arranged between the first element 3 and the third element 32 such that the third element 32 is moved against 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 (

[0170] ). Figure 32 ) A connection with the protrusion 22 is established through a snap hook connection, in which the second element 4 forms a form-locking connection with the window 31 in the protrusion 22 relative to the installation direction 27 (see

[0171] ). Here, the second element 4 cooperates with the protrusion 22 such that as the swing of the second element 4 increases, the cover 2 continues to be displaced along the installation direction 27 towards the fastening plate 21 during the lifting movement 29.
