Description

Technical Field

[0001] The invention relates to a closure element for a drain opening of a sanitary basin, in particular a sink, comprising a base body having an upper side and a lower side opposite the upper side, wherein a handle device is arranged on the upper side and the upper side has a recess, in particular arranged centrally on the upper side, in which the handle device is arranged.

[0002] The invention further relates to a closure system comprising a basin, in particular a sanitary basin, having a drain opening and a closure element for closing the drain opening. Background Art

[0003] Although the invention is generally applicable to any closure element, the invention is explained in conjunction with a closure element for use in a drain fitting for a sink.

[0004] For example, sinks in kitchens usually have a drain fitting for draining the flushing water from the sink. In order to prevent dirt from entering the pipe connected to the drain fitting, it is known to use a so-called filter basket, which allows the dirty water to be drained away and at the same time blocks coarser dirt (e.g. food residues etc.). It is also known to use a sealing plug instead of a filter basket, which can make the sink more reliably sealed, for example if no dirt is desired or required when reopening the drain. The filter basket is designed in a known manner in the shape of a flat bowl and has a passage opening for draining the dirty water, while the sealing plug is made of rubber or plastic, for example. In addition, a handle or a chain can also be arranged in a known manner in the center of the closing plug.

[0005] Disadvantages here are: firstly, low quality and poor handling, for example, only a chain for pulling out the sealing plug without a handle, and poor fit, because the sealing plug does not cover and seal the opening of the sieve basket, but only directly covers and seals the drain opening. In addition, if the liquid jet hits the plug at an unfavorable angle, for example, the liquid jet is emitted from the outlet of the sanitary fitting arranged above the plug, the liquid will quickly flow to the handle and from there be deflected upwards or sprayed towards the user of the sanitary fitting. Summary of the invention

[0006] The object of the present invention is therefore to provide a closure element and a closure system which can be manufactured cost-effectively, which at least partially suppress or prevent the emission of a liquid jet in the direction of a user in a simple and reliable manner and which at the same time provides good visual appearance, haptics, quality and operability.

[0007] Another object of the present invention is to provide an alternative closure element and an alternative closure system.

[0008] In one embodiment, the present invention solves the above-mentioned problem by utilizing a closing element for a drain opening of a sanitary basin, in particular a sink, the closing element comprising a base body having an upper side and a lower side opposite to the upper side, wherein a handle device is arranged on the upper side, and the upper side has a recess, in particular centrally arranged on the upper side, in which the handle device is arranged, and at least one sealing element is arranged on the lower side, so that when the closing element is at least partially arranged in the drain opening of the sanitary basin, the closing element closes the drain opening in a liquid-tight manner.

[0009] In one embodiment, the invention solves the above-mentioned problem with a closure system comprising a basin, in particular a sanitary basin, having a drain opening and a closure element according to any one of claims 1 to 22 for closing the drain opening.

[0010] One of the advantages achieved is that a closure element with a high sealing effect and at the same time a high quality, haptics and operability is provided in a particularly simple manner. Another advantage is high user satisfaction and an improved visual appearance.

[0011] The term "sanitary" is to be understood in the broadest sense and, in particular in the claims and preferably in the description, generally refers to the kitchen area, the bathroom area or the laundry area and the heating area.

[0012] The term "flow interrupter" is to be understood in the broadest sense and refers in particular in the claims and preferably in the description generally to any device or apparatus having a segment, surface or area designed to change the flow direction or liquid flow direction of a liquid abruptly and / or with a discontinuous curvature, so that at least a portion of the liquid is directed substantially back to the original direction of the liquid flow. The flow interrupter provides the aforementioned effect of a sudden change in flow direction, in particular when the flow is slow and / or the amount of liquid is small compared to the volume of the recess and the height of the handle device above the deepest area of ​​the recess.

[0013] Other features, advantages and other embodiments of the invention will be described below or will be apparent from the invention.

[0014] According to an advantageous improvement of the invention, the closure element is designed as a multi-piece, in particular a four-piece or five-piece, or as a one-piece. The one-piece design has the advantage of being easy to handle and manufacture. The multi-piece design has the advantage of greater flexibility in the design of the individual components.

[0015] According to another advantageous development of the invention, the handle device is detachably arranged on the base body, in particular by means of a snap-in connection. One of the advantages achieved is rapid assembly and disassembly, which enables particularly reliable and thorough cleaning of the closure element.

[0016] According to another advantageous development of the invention, the handle device can be fixed in an opening of the base body, in particular, the opening is clover-shaped. One of the advantages achieved is rapid assembly and disassembly, which enables particularly reliable and thorough cleaning of the closure element.

[0017] According to another advantageous development of the invention, the handle device has a flow interrupter, in particular a dividing edge, for a liquid flow flowing in the direction of the deeper surface area of ​​the upper side of the base body, so that the liquid flow in the deeper area is at least partially interrupted by the flow interrupter. One of the advantages achieved is that a liquid jet splashing toward the user can be at least partially suppressed in a simple and reliable manner. By means of the dividing edge, the liquid flow is guided, in particular at least partially guided to the original direction, but the liquid flow is at least partially reduced at an acute angle, perpendicular to the actuation direction of the closure element, in particular in the form of a vertical direction.

[0018] According to another advantageous development of the invention, the handle device is designed as a single piece or multi-piece, in particular two-piece, comprising at least a handle base and a cap. This has the advantage that the handle device can be mounted quickly and easily. In addition, the cap can be easily customized to different users. For example, the cap can be provided with a coating, in particular a varnish or the like. A single-piece handle device is easy to manufacture and allows rapid assembly on the base of the closure element.

[0019] According to another advantageous improvement of the present invention, the handle device can be fixed on different sides of the substrate. This has the advantage that the handle device can be fixed particularly reliably, because the handle device can be fastened in this way, for example against forces acting parallel to the actuation direction of the closure element.

[0020] According to another advantageous development of the invention, the handle device and the opening are designed to cooperate with each other to provide a torsion resistance of the handle device in the opening, in particular the opening is designed in a clover-shaped manner. One of the advantages achieved is that the closure element can be operated reliably and the user is prevented from getting angry when operating the closure element.

[0021] According to another advantageous improvement of the present invention, the shut-off device, in particular the cutting edge, is arranged on the handle base. The advantage of doing so is that a high optical or high-quality impression can be obtained when the closure element is activated.

[0022] According to another advantageous development of the invention, the cap is fixed to the handle base body by positive locking, material locking and / or friction locking, in particular by pressing and / or bonding. This has the advantage that the cap is fixed to the handle base body simply and reliably.

[0023] According to another advantageous development of the invention, the cap at least partially projects beyond the cut-off device, in particular beyond the tear-off edge. On the one hand, this conceals or covers the cut-off device, in particular the tear-off edge, so as to maintain a high visual appearance. At the same time, by partially forming a space that is enclosed in three directions, in particular in the form of a cavity, the effect of the cut-off device, in particular the tear-off edge, can be further enhanced.

[0024] According to another advantageous development of the invention, the handle base has at least two radial projections distributed over the circumference. As a result, the cap can be securely fixed to the handle base in a friction-locking manner by pushing the cap over the projections. To achieve this, the projections can be designed in a chamfered, rounded, etc. manner in the corresponding direction.

[0025] According to another advantageous development of the invention, the flow interruption device, in particular the dividing edge, comprises a setback, in particular the setback comprises at least one edge of at least 90 degrees. As a result, the dividing edge is designed in a particularly reliable manner to be visually inconspicuous, and on the other hand, the effect of the dividing edge in interrupting and partially redirecting the liquid flow is improved.

[0026] According to another advantageous development of the invention, the surface has at least two passage openings, in particular passage openings in the form of slits, which are closed by at least one sealing element. This achieves a strong visual effect, while the closed openings can prevent liquid from splashing out. Preferably, the surface or the upper side of the base body in the area of ​​the handle device is designed to be flat or horizontal.

[0027] According to another advantageous improvement of the present invention, the channel opening is at least partially arranged in the deeper region, in particular the channel opening is connected to the opening of the base body. This has the advantage of simple manufacturing and improved anti-sputtering effect.

[0028] According to another advantageous development of the invention, at least one sealing element covers the passage opening and / or can be fastened to the passage opening. If a plurality of sealing elements are arranged, one, a plurality or all of the sealing elements can cover the passage opening and / or can be fastened to the passage opening. This has the advantage that the sealing element can be fastened particularly simply and reliably with a good sealing effect and can also provide additional torsion resistance if necessary.

[0029] According to another advantageous development of the invention, at least one sealing element is arranged on the carrier element, in particular the carrier element has a projection which can be partially introduced into the passage opening for detachably fixing the carrier element to the base body. This provides a high degree of flexibility in the arrangement of different closing elements.

[0030] According to another advantageous development of the invention, the carrier element is designed to be substantially flat, in particular the carrier element extends substantially parallel to the underside of the base body. This has the advantage that it can be easily retrofitted, since only a small amount of structural space is required below the base body.

[0031] According to another advantageous development of the invention, the carrier element has at least one vertical projection, which is designed in particular for contact with the underside of the base body in a positively locking manner, and / or at least one horizontal projection, which is designed for receiving at least one sealing element. This has the advantage that the sealing element can be arranged in a simple and defined manner while ensuring a reliable sealing effect.

[0032] According to another advantageous development of the invention, at least one sealing element and the carrier element are produced by means of two-component injection molding, which makes production simple and cost-effective.

[0033] According to another advantageous development of the invention, the top and / or bottom side has at least one projection, in particular in the form of an embossing, and wherein at least one sealing element and / or carrier element has at least one corresponding depression and / or at least one projection relative to the at least one projection of the top and / or bottom side. As a result, an undesired twisting of the sealing element and / or carrier element relative to the base body can be easily and reliably avoided by the engagement of the projection or depression in the corresponding embossing.

[0034] According to another advantageous improvement of the present invention, at least one sealing element is designed as a lip seal or a flat seal. This has the advantages of good sealing effect, small construction space and easy modification.

[0035] Further important features and advantages of the invention emerge from the dependent claims, from the drawings and from the associated figure description of the drawings.

[0036] Of course, the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination but also in other combinations or alone, without departing from the scope of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Figure 1 and Figure 2 A closure element according to an embodiment of the invention is shown in an exploded view and in a cross-sectional view.

[0047] exist Figure 1 and Figure 2 , shown in the drain cup A (only Figure 2 ) in a closure element 1. The closure element 1 is designed in multiple parts and comprises a base body 4 and a handle, which comprises a handle base body 3 with a cap 2. In this case, the handle base body 3 is partially guided through an opening 4b of the base body 4 and is fixed on the opposite side of the base body 4 by means of a locking ring 5.

[0048] In detail, the substantially cylindrical cap 2 has a rounded protrusion in its upper region 2a. The central region 2b of the cap is curved radially inwardly so that the edge of the cap 2 in the lower region 2c has substantially the same outer diameter as the upper region 2a.

[0049] The handle base 3 is designed essentially in the form of a ring. In the upper region 3a, the ring has a protruding shoulder that is folded back laterally toward the base 4. In the central region 3b, the side faces extend in a straight line in cross section, and in the lower region 3c, the ring has a setback K to form a dividing edge. Here, the setback K is designed in a triangular shape in cross section, wherein a 90-degree angle is formed between the central region 3b and the dividing edge. In addition, the cap 2 can extend downward in a substantially vertical direction beyond the dividing edge or the setback K, as shown in Figure 2 As shown on the right side of the cap 2. Figure 2 On the left side, the lower region 2c of the cap ends at the height of the cutting edge or the setback K and does not protrude beyond the cutting edge or the setback.

[0050] Furthermore, the handle base body 3 has, in the lower region 3 c , a projection 3 g which is convex in the vertical direction and is arc-shaped, ie, is curved in the direction of the radial outside.

[0051] If the liquid now flows in the direction F0, i.e. in the direction of the handles 2, 3, the liquid flow is deflected upward by the dividing edge K to a lesser extent (reference numeral F2) than in the case of no constriction K, in particular in the case of rounding (reference numeral F1). This also applies analogously to the other Figures 3 to 10 .

[0052] The base body 4 has a recessed portion designed in a flat bowl shape, which has a flat horizontal edge 4e surrounding the outside, which transitions into a curved, downwardly inclined surface 4d. In the curved surface 4d, radially oriented, elongated slits 4a are arranged regularly distributed on the circumference. In the deepest area in the center of the screen surface 4, an opening 4b with a clover-shaped cross section is formed.

[0053] To assemble the closure element 1, the cap 2 is first inserted onto the handle base 3 and thereby fixed in a friction-locking and / or material-locking manner, for example by adhesive bonding. Figure 1 and Figure 2 The lower part shown is inserted into the opening 4b of the base body 4 starting from the upper side 40 of the base body 4, so that the projection 3g passes through the opening 4b to the lower side 41 of the base body. Subsequently, the carrier element 42 is inserted onto the projection 3g, of which the fastening ring 5 is an integral component. The fastening ring 5 can also be designed as a separate component. Figure 1 and Figure 2 In the embodiment, the fastening ring 5 is designed as an opening in the carrier element 42, and has a clover-shaped cross section on its inner side corresponding to the opening 4b in cross section, and the cross section has a recess 5c. The fastening ring 5 has a vertical protrusion 5b on its upper side, that is, the surface oriented toward the base body 4, and the position of the vertical protrusion corresponds to the recess or protrusion extending in the clover shape on the inner side. On the carrier element 42, one or more sealing elements 43 are arranged in the receiving portion 42c, in particular inserted in the receiving portion 42c. The protrusion 3g passing through the carrier element 42 is fixed to the fastening ring 5 on the opposite side. This can be achieved, for example, by bonding the protrusion 3g to the fastening ring 5. Here, the protrusion 3g corresponds to the protrusion 4c on the inner side of the opening 4b.

[0054] Overall, it is possible to provide that the handles 2, 3 are rotationally fixed relative to the base body 4. The vertical projections 5b of the fastening ring 5 serve to correctly space the carrier element 42 and the projections 3g relative to the opening 4b.

[0055] At least one X-ring or O-ring is arranged circumferentially on the carrier element 42 as a sealing element 43. It is also conceivable to use a lip seal as a sealing element 43.

[0056] Here, the cap 2 and / or the handle base 3 and / or the base 4 and / or the fastening ring 5 and / or the carrier element 42 can each be made at least partially, in particular completely, of metal and / or plastic. For example, the plastic can include polyamide and polypropylene and / or be designed to be reinforced with glass fibers. The cap 2 and / or the base 4 can be coated with paint, etc., for example. The sealing element 43 can be made of rubber and / or plastic, in particular injection molded onto the carrier element 42.

[0057] Figure 3 A closure element according to an embodiment of the invention is shown in cross section.

[0058] Figure 3 Mainly show that according to Figure 1 and Figure 2 The closing element 1. Figure 1 and Figure 2 The closure element 1 is compared to the Figure 3 The closure element now has a closure cap 2 which is designed to extend in the lower region 2c in the direction of the handle base 3, thereby forming an "overhang" relative to the handle base 3. In this way, a cutting edge or setback K is formed. Thus, the lower edge of the lower region 2c of the cap 2 can be bent radially inwards completely or partially. This also applies to all other embodiments.

[0059] The cap 2 is also curved radially inwards in the middle region 2b. In other words, the cap is designed in the shape of a circular arc in cross section in the central region.

[0060] Figure 4 and Figure 5 A closure element according to an embodiment of the invention is shown in an exploded view and in a cross-sectional view.

[0061] Figure 4 and Figure 5 Basic indication based on Fig.13 The closing element 1. According to Figures 1 to 3 The closure element 1 is different, in accordance with Figure 4 and Figure 5In the closure element 1, radial protrusions 3d extend on the upper and middle regions 3a, 3b of the handle base 3, the radial protrusions are triangular in cross section, extend substantially in the vertical direction in the regions 3a, 3b, and are arranged in a regular manner on the radial outer side of the handle base 3. Through the above-mentioned protrusions 3d, the cap 2 can be fixed on the handle base 3 by friction locking. In order to easily assemble the cap 2, the protrusion 3d can be designed as a circle or a flat in the upper region. In addition, the opening 4b is now circular and does not have a "cloverleaf shape". The carrier element or the sealing element 42, 43 seals the passage that may exist between the opening 4b and the handle base 3.

[0062] Figure 6 and Figure 7 A closure element according to an embodiment of the invention is shown in an exploded view and in a cross-sectional view.

[0063] Figure 6 and Figure 7 Mainly show that according to Figure 4 and Figure 5 The closing element 1. According to Figure 4 and Figure 5 Compared with the closure element 4, Figure 6 and 7 The closing element 4 has Figure 4 and Figure 5 Some differences are shown. On the one hand, the vertical surrounding crosspiece 4g extends around the opening 4b upwards in the direction of the base body 3, and on the other hand, the opening slit 4a reaches the opening 4b, but is not connected to the opening. The vertical protrusion 5b of the fastening ring 5 of the carrier element 42 on its upper side is designed so that the vertical protrusion engages in the opening slit 4a of the base body 4 in the region of the crosspiece 4g. Similarly, the V-shaped edge 3f of the protrusion 3g engages in the clover-shaped protrusion 5e of the inner face of the fastening ring 5 of the carrier element 42. In this way, an anti-twist mechanism can be provided.

[0064] The projection 3g on the handle base body 3 is folded back toward the radial inner side of the handle base body 3. In other words, the projection 3g is designed in a V shape, wherein the corresponding edge 3f extends vertically and is arranged radially more inward.

[0065] Furthermore, the carrier element 42 has a thickness that decreases in the radially outward direction, Figure 7 The vertical extension of the carrier element 42. Figure 6 and Figure 7 In the embodiment, a lip seal 43 a is arranged as the sealing element 43 on the radial outer side of the carrier element 42 .

[0066] Figure 8 and Fig. 9 A closure element according to an embodiment of the invention is shown in an exploded view and in a cross-sectional view.

[0067] Figure 8 and Fig. 9 Mainly show that according to Figure 1 and Figure 2 The closing element 1. According to Figure 1 and Figure 2 The closure element 1 is distinguished according to Figure 8 and Fig. 9 The closure element 1 now has a one-piece handle 23 which corresponds on its upper side to the Figure 6 and Figure 7 The cap 2, in particular the regions 23a, 23b, 23c, corresponds substantially to the Figure 6 and Figure 7 The cap 2 has regions 2a, 2b, 2c. On the lower side, the handle 23 now has a web 23e and a slit 23e' in a circumferential manner. In addition, in the circumferential direction around the handle base 3, two protrusions 23f, 23g are arranged on the web 23e at a distance from each other in the vertical direction, interrupted only by the slit 23e'.

[0068] In addition, the substrate 4 is Figures 1 to 7 The base 4 of the carrier element 42 is different from the base 4 of the carrier element 42. The opening 4b is no longer a "clover shape", but is designed to be circular and has a rectangular tooth portion 4h protruding inward. In addition, the area 4f around the opening 4b is flattened, that is, horizontally and parallel to the edge 4e. The vertical protrusion 5b of the fastening ring 5 of the carrier element 42 does not exist; instead, a radially inwardly protruding protrusion 5h is formed, which abuts against the tooth portion 4h when the handle 23 is assembled into the opening 4b. Then, the tooth portion 4h and the protrusion 5h are arranged in the slit 23e'. Here, the cutting edge K is designed in the form of a rounded recess in cross section, which extends partially upward in the vertical direction.

[0069] Fig.10 , Fig.11 and Fig.12 A closure element according to an embodiment of the invention is shown in an exploded view, a cross-sectional view and a bottom view.

[0070] exist Figures 10 to 12 The main points are shown in Figure 8 and Fig. 9 The closing element 1. According to Figure 8 and Fig. 9 The closure element 1 is compared to the Figures 10 to 12 The closing element 1 is similar to Figures 1 to 7 The ground is designed as a multi-piece.

[0071] Furthermore, the carrier element 42 has a vertical elevation or projection 42d on its surface facing the base body 4, on a vertically protruding, circumferential edge 42b which is adapted to the extension of the base body 4. The projection 42d is designed such that it can protrude into the elongated slit 4a or can be at least partially pressed into it. The carrier element 42 is thus detachably fixed in the base body 4 in its slit 4a in a rotationally fixed manner.

[0072] The carrier element 42 has a circumferential protrusion 42a extending horizontally on its radial outer side, into which the sealing element 43 can be fixed in a clamping or positive locking manner. For this purpose, the sealing element 43 has a circumferential opening or recess 43b corresponding to the protrusion 42a, for example, configured in a U shape.

[0073] Typically, for each embodiment, convex and / or concave embossings can also be arranged instead of the elongated slits 4a. The sealing element 43 and / or the carrier element 42 can then engage into these embossings by means of projections, as just described for the slits 4a and / or the setbacks, thereby providing an additional anti-twist mechanism. Typically, for each embodiment, the connection between the handle base 3 and the carrier element 42 and thus also the base 4 can be fixed in a detachable manner, for example by means of a clamping or snap-in connection. Typically, for each embodiment, the fastening ring 5 can be integrally formed in the carrier element 42 as shown or the carrier element 42 fixed to the handle base 3 and the base 4 can be fastened or fixed separately from below.
