Description

[0001] Device for flushing a toilet

[0002] The present invention relates to a device for flushing a toilet. Such toilets are used, in particular, to collect bodily excretions.

[0003] Toilets typically have a toilet bowl that can be cleaned by flushing after use. The flush may, for example, have a cistern for holding a flushing fluid, with the flow of the flushing fluid from the cistern into the toilet bowl being controllable via a drain valve. The drain valve can be actuated by a toilet user via at least one actuating button on the device.

[0004] The device is usually arranged in an inspection shaft of a wall and covered with a (particularly decorative) cover plate. The cover plate comprises at least one actuating button and an actuating mechanism. To meet the different tastes and preferences of customers, the cover plates and / or actuating buttons are offered in a variety of different visual designs. If the visual design or geometry of the cover plate and / or the at least one actuating button changes, the actuating mechanism often has to be adapted to the changed design or geometry. The changed actuating mechanism often requires an adaptation of the housing of the device so that the cover plate can be attached to the device or housing. This leads to a high variety of parts.

[0005] The object of the invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to provide a device for actuating a toilet flush with which the variety of parts can be reduced. This object is achieved with a device according to the features of the independent patent claim. Further advantageous embodiments of the invention are specified in the dependent patent claims. It should be noted that the features individually listed in the patent claims can be combined with one another in any technologically expedient manner and define further embodiments of the invention. Furthermore, the features specified in the patent claims are specified and explained in more detail in the description, with further preferred embodiments of the invention being presented.

[0012] The toilet can, in particular, be designed in the manner of a (sit-up) toilet or a urinal. Furthermore, the toilet can have a toilet bowl that can be cleaned by flushing. Cleaning occurs, in particular, by means of a flushing liquid, the release of which into the toilet bowl can be activated by at least one actuating button of a device for actuating the flush of the toilet. The flush can have a cistern for holding the flushing liquid and / or a drain valve for controlling the release of the flushing liquid to the toilet bowl. The flush can be at least partially attached to a mounting frame of the toilet, by means of which the toilet can be attached to a wall of a building. Such mounting frames are known, for example, as pre-wall elements. These are attached to the wall of the building and then covered with a pre-wall. Wall cladding elements, for example in the style of tiles, can in turn be attached to the pre-wall.An inspection shaft or opening can be formed in the wall and / or the front wall. The device or a housing of the device can be arranged, in particular, at least partially in the inspection shaft or in the opening. The cistern of the flushing system can be arranged, in particular, behind the device in the wall or in a cavity between the wall and the front wall.

[0013] The housing of the device can be made at least partially of plastic and / or metal. For example, the housing can be a plastic injection-molded part. An assembly space is formed in the housing of the device. The assembly space can extend from an assembly space opening of the housing into the housing. When the device is assembled, the assembly space opening can be aligned, in particular, with the inspection shaft or with the opening in the wall and / or pre-wall. The assembly space opening can extend orthogonally to a longitudinal axis of the housing or of the assembly space. The longitudinal axis can be a central axis of the housing or of the assembly space. The longitudinal axis can extend through the assembly space at least partially centrally and / or concentrically to the assembly space. The longitudinal axis can extend through the assembly space at least partially centrally and / or concentrically to the assembly space.The housing can have side walls that at least partially delimit the mounting space. At least one first guide and at least one second guide are formed in the mounting space. The at least one first guide and / or the at least one second guide are in particular only formed within the mounting space. The at least one first guide and / or the at least one second guide can be at least partially formed or arranged in and / or on at least one side wall of the housing, which in particular delimits the mounting space. The at least one first guide and the at least one second guide extend in particular (essentially) parallel to the longitudinal axis. In this context, an extension parallel to the longitudinal axis can also be understood to mean in particular an extension of the at least one first guide and / or the at least one second guide, which may, for example, be slightly (e.g.by up to + / - 10°) at an angle to the longitudinal axis. The at least one first guide and the at least one second guide extend in particular parallel to one another. The at least one first guide and the at least one second guide can be at a distance from one another (in particular orthogonal to the longitudinal axis). The distance can be, for example, 50 mm [millimeters] to 150 mm, preferably 80 mm to 120 mm. The at least one first guide and / or the at least one second guide can have (in particular parallel to the longitudinal axis) a guide length or an extension of, for example, 20 mm to 100 mm, preferably 60 mm to 80 mm. The at least one first guide and / or the at least one second guide can be a sliding guide and / or a linear guide. The at least one first guide and / or the at least one second guide enable, in particular, a straight movement.

[0014] The device comprises a pressure generator. The pressure generator is arranged at least partially or entirely within the assembly space. Compressed air can be generated by the pressure generator. The pressure generator can be manual or electric. The pressure generator can be, for example, an air pump or bellows. The pressure generator can comprise a cylinder in which a piston is movable. The discharge valve can be controlled using the compressed air generated by the pressure generator. The pressure generator can be connected to the discharge valve via a compressed air line, via which the compressed air can be supplied to the discharge valve.

[0015] The device has an actuating body for the pressure generator. The actuating body is arranged at least partially or completely in the assembly space of the housing. The actuating body can be connected, in particular directly, to the pressure generator and / or contact the pressure generator. The actuating body can be made at least partially of plastic and / or metal. The actuating body can be a plastic injection-molded part. The pressure generator can be actuated via the actuating body. For example, the piston in the cylinder can be moved and / or the bellows can be pressed via the actuating body. The actuating body is arranged so as to be movable, in particular parallel to the longitudinal axis, between a basic position and a flushing position. In this context, mobility parallel to the longitudinal axis can also be understood to mean mobility of the actuating body which, for example, may be slightly (e.g.by up to + / - 10°) to the longitudinal axis. In particular, the pressure generator can be actuated during the movement of the actuating body and / or by the movement of the actuating body. In the basic position of the actuating body, in particular no compressed air is generated by the pressure generator. When the actuating body moves in the direction of the flushing position and / or in the flushing position, the actuating body can actuate the pressure generator in such a way that the pressure generator generates compressed air. When the actuating body moves in the direction of the flushing position, the actuating body can move the piston in the cylinder of the pressure generator and / or press the bellows.

[0016] The device has a first key carrier for a first actuation key. The first key carrier is arranged at least partially or completely in the mounting space of the housing. The first key carrier can be made at least partially of plastic and / or metal. The first key carrier can be a plastic injection-molded part. The first key carrier is movably fastened, in particular, in the at least one first guide. The first key carrier is movable by the at least one first guide or in the at least one first guide, in particular parallel to the longitudinal axis, between a first initial position and a first actuation position, in particular linearly or along a straight travel path. In this context, mobility parallel to the longitudinal axis can also be understood to mean mobility of the first key carrier, which may, for example, be slightly (e.g.by up to + / - 10°) to the longitudinal axis. When the first button carrier moves from the first starting position to the first actuating position, the actuating body can be moved by the first button carrier from the home position to the (first) flushing position. When the first button carrier moves into the first actuating position, the first button carrier in particular contacts the actuating body so that the actuating body is moved or pressed into the (first) flushing position. When the first button carrier moves from the first starting position to the first actuating position and / or when the actuating body moves from the home position to the (first) flushing position, a first quantity of compressed air can be generated by the pressure generator. The first button carrier can be reset to the first starting position by a first spring. The first spring can be a helical spring.

[0017] The first button carrier can have a first support surface for the first actuating button. The first support surface can extend (essentially) orthogonal to the longitudinal axis and / or parallel to the assembly space opening. The first actuating button can contact the first button carrier at the first support surface and / or be fastened to the first support surface, for example by means of a snap connection. The first button carrier can be moved by the first actuating button and / or via the first support surface from the first starting position into the first actuating position, in particular when the first actuating button is pressed by a user parallel to the longitudinal axis. The first button carrier can have a first cross member. The first button carrier can have a first receiving portion which extends from the first cross member, in particular parallel to the longitudinal axis, in the direction of the assembly space opening.The first receiving section can be formed, in particular precisely, between the first longitudinal ends of the first key carrier or the first cross member. The first support surface can be formed at a first projecting end of the first receiving section.

[0018] The device has a second key carrier for a second actuation key. The second key carrier is arranged at least partially or completely in the mounting space of the housing. The second key carrier can be made at least partially of plastic and / or metal. The second key carrier can be a plastic injection-molded part. The second key carrier is movably mounted, in particular, in the at least one second guide. The second key carrier is movable by the at least one second guide or in the at least one second guide, in particular parallel to the longitudinal axis, between a second initial position and a second actuation position, in particular linearly or along a straight travel path. In this context, mobility parallel to the longitudinal axis can also be understood to mean mobility of the second key carrier, which may, for example, be slightly (e.g.by up to + / - 10°) to the longitudinal axis. When the second button carrier moves from the second starting position to the second actuating position, the actuating body can be moved by the second button carrier from the home position to the (second) flushing position. When the second button carrier moves into the second actuating position, the second button carrier in particular contacts the actuating body so that the actuating body is moved or pressed into the (second) flushing position. When the second button carrier moves from the second starting position to the second actuating position and / or when the actuating body moves from the home position to the (second) flushing position, a second quantity of compressed air can be generated by the pressure generator. The second quantity of compressed air can be greater than the first quantity of compressed air.As a result, two different amounts of rinsing liquid can be dispensed through the drain valve, for example a small amount of rinsing liquid and a large amount of rinsing liquid. The second button carrier can be reset to the second starting position by a second spring. The second spring can be a coil spring. The second button carrier can have a second support surface for the second actuating button. The second support surface can extend (essentially) orthogonal to the longitudinal axis and / or parallel to the assembly space opening. The second actuating button can contact the second button carrier at the second support surface and / or be fastened to the second support surface, for example by means of a snap connection.The second button carrier can be moved from the second starting position into the second actuating position by the second actuating button and / or via the second support surface, in particular when the second actuating button is pressed by the user parallel to the longitudinal axis. The second button carrier can have a second cross member. The second button carrier can have a second receiving section which extends from the second cross member, in particular parallel to the longitudinal axis, in the direction of the assembly space opening. The second receiving section can be formed, in particular exactly, between second longitudinal ends of the second button carrier or the second cross member. The second support surface can be formed at a second projecting end of the second receiving section.

The at least one third guide can be formed or arranged at least partially in and / or on the at least one side wall of the housing, which in particular delimits the mounting space. The at least one third guide extends in particular parallel to the longitudinal axis. In this context, an extension parallel to the longitudinal axis can also be understood in particular to mean an extension of the at least one third guide which, for example due to manufacturing tolerances, runs at a slight angle (e.g. by up to + / - 10°) to the longitudinal axis. The at least one third guide can extend at least partially parallel to the at least one first guide and / or the at least one second guide.The at least one third guide can be arranged or formed between the at least one first guide and the at least one second guide.

The first pin and / or the second pin can extend from the actuating body or the third cross member parallel to the longitudinal axis in the direction of the assembly space opening. A first receptacle can be formed in the first receptacle section of the first cross member of the first button carrier, with which receptacle the first button carrier can be plugged onto the first pin of the actuating body. The first receptacle can be designed in the manner of a bore and / or extend parallel to the longitudinal axis. The first spring can be arranged in the first receptacle and can in particular surround the first pin. The first spring can press the first button carrier into the first starting position.A second receptacle can be formed in the second receiving section of the second cross member of the second key support, with which the second key support can be plugged onto the second pin of the actuating body. The second receptacle can be designed in the manner of a bore and extend parallel to the longitudinal axis. The second spring can be arranged in the second receptacle and can, in particular, surround the second pin. The second spring can press the second key support into the second starting position.

[0023] The mounting opening of the mounting space can be covered with a cover plate, which can accommodate the first actuating button and the second actuating button. The cover plate can be fastened to the device or the housing, for example via a snap connection. The button carriers and the actuating body form a uniform actuating mechanism or a uniform interface in the device, onto which different design variants of the cover plates can be mounted. In particular, the cover plates can be exchanged without the button carriers and / or without the actuating body. Adaptation of the button carriers, the actuating body and / or the housing of the device can thus be avoided, thereby reducing the variety of parts. The device can be designed as a modular system and / or allow a high degree of design freedom for the cover plate or the actuating buttons.Two first guides for the first key carrier and / or two second guides for the second key carrier can be formed in the assembly space. Two third guides for the actuating body can be formed in the assembly space. The first guides can be arranged opposite one another, in particular with mirror symmetry. The second guides can be arranged opposite one another, in particular with mirror symmetry. The third guides can be arranged opposite one another, in particular with mirror symmetry. The first guides can be spaced a first distance apart, the second guides can be spaced a second distance apart and / or the third guides can be spaced a third distance apart. The first distance, the second distance and / or the third distance can be, for example, 50 mm to 150 mm, preferably 80 mm to 120 mm.

[0025] The at least one first guide, the at least one second guide, and / or at least one third guide of the housing for the actuating body can have at least one guide web. The at least one guide web can be a sliding web. The at least one guide web can protrude from at least one guide surface of the at least one first guide, the at least one second guide, and / or the at least one third guide. The at least one guide web can have a straight course. The at least one guide web can have a sliding surface for the first key carrier, the second key carrier, and / or the actuating body, which sliding surface runs (in particular exactly) parallel to the longitudinal axis. This enables 0° demolding from an injection molding tool during production of the housing. The at least one guide web can extend along the entire first guide, second guide, and / or third guide.The at least one guide web can have (in particular orthogonal to the longitudinal axis and / or orthogonal to a longitudinal extension of the at least one guide web) a web width that is in particular smaller than a width of the guide surface on which the at least one guide web is formed. The web width can be, for example, 0.5 mm to 5 mm. The at least one guide web can have (in particular starting from the respective guide surface of the guide web, orthogonal to the web width and / or orthogonal to the longitudinal axis) a web height of, for example, 1 mm to 5 mm. The at least one guide web can prevent contact between the first key carrier, the second key carrier and / or the actuating body on the one hand and other regions of the respective guide on the other.The at least one guide web is particularly designed such that the first key carrier, the second key carrier, and / or the actuating body in the respective guide only contacts the at least one guide web or can only slide on the at least one guide web. The at least one guide web can prevent contact of the first key carrier, the second key carrier, and / or the actuating body with the at least one guide surface. The at least one first guide, the at least one second guide, and / or the at least one third guide can each have three guide surfaces, each with a guide web.

[0026] The at least one guide web reduces friction during movement of the first key carrier, the second key carrier, and / or the actuating body in the respective guide. The at least one guide web can prevent tilting, jamming, and / or misalignment of the first key carrier, the second key carrier, the actuating body, the first actuating button, and / or the second actuating button. The at least one guide web can be used to create a floating bearing between the cover plate, on the one hand, and the first actuating button and the second actuating button, on the other. This allows the first actuating button and the second actuating button to center themselves in the cover plate.

[0027] The at least one guide web can extend parallel to the longitudinal axis of the housing.

[0028] The at least one guide web can have a convex sliding surface.

The at least one first sliding projection can have (in particular parallel to the longitudinal axis) a first projection length of, for example, 1 mm to 10 mm and / or (in particular orthogonal to the longitudinal axis and / or orthogonal to the projection length) a first projection width of, for example, 1 mm to 10 mm. The first key carrier contacts the at least one first guide orthe at least one guide web of the at least one first guide, in particular only with the at least one first sliding projection. The at least one first sliding projection can be formed, in particular only, on at least one of two first guide section ends of the at least one first guide section. The at least one first sliding projection can reduce the friction between the first key carrier and the at least one first guide. The at least one second sliding projection protrudes, in particular, from a second guide section surface of the at least one second guide section, for example, with a second height of 0.5 mm to 5 mm.The at least one second sliding projection can have (in particular parallel to the longitudinal axis) a second projection length of, for example, 1 mm to 10 mm and / or (in particular orthogonal to the longitudinal axis and / or orthogonal to the projection length) a second projection width of, for example, 1 mm to 10 mm. The second key carrier contacts the at least one second guide or the at least one guide web of the at least one second guide, in particular only with the at least one second sliding projection. The at least one second sliding projection can be formed, in particular only, on at least one of two second guide section ends of the at least one second guide section. The at least one second sliding projection can reduce the friction between the second key carrier and the at least one second guide.

[0030] When the first key carrier moves, the at least one first sliding projection can slide on at least one first guide web of the at least one first guide and / or when the second key carrier moves, the at least one second sliding projection can slide on at least one second guide web of the at least one second guide.

[0031] The actuating body can have at least one third guide section, which is guided in at least one third guide of the housing for the actuating body and which has at least one third sliding projection.

The at least one third sliding projection can have (in particular parallel to the longitudinal axis) a third projection length of, for example, 1 mm to 10 mm and / or (in particular orthogonal to the longitudinal axis and / or orthogonal to the projection length) a third projection width of, for example, 1 mm to 10 mm. The actuating body contacts the at least one third guide or the at least one guide web of the at least one third guide, in particular only with the at least one third sliding projection.The at least one third sliding projection can be formed, in particular only, on at least one of two third guide section ends of the at least one third guide section. The at least one third sliding projection reduces the friction between the first key carrier and the at least one third guide.

[0032] When the actuating body moves, the at least one third sliding projection can slide on at least one third guide web of the at least one third guide.

The guide surfaces 64, 65, 66 each have a first guide web 18.1, 18.2, 18.3. The guide webs 18.1, 18.2, 18.3 protrude from the guide surfaces 64, 65, 66 and extend parallel to the longitudinal axis 9 shown in Figs. 3, 4, and 7 along the entire first guide 6.1. the guide webs 18.1, 18.2, 18.3 each have a convex sliding surface 19.

[0054] Fig. 9 shows a detailed view of the first guide 6.1 with the first guide section 20.1 of the first key carrier 12. Due to the convex sliding surfaces 19 of the guide webs 18.1, 18.2, 18.3, the first sliding projections 23 of the first guide section surfaces 58 of the first guide section 20.1 contact the guide webs 18.1, 18.2, 18.3 in a linear manner, thus reducing friction during the movement of the first key carrier 12 in the first guide 6.1.

[0055] The guides 6.2, 7.1, 7.2, 8.1, 8.2 shown in Fig. 3 can be designed correspondingly to the first guide 6.1 shown in Fig. 8 and 9 and / or identically to the first guide 6.1 shown in Fig. 8 and 9.
