Description

  The present invention includes a housing, a cover rosette, and a connecting device, wherein the housing is attached to the outer wall of the sanitary tub and includes a drainage connecting portion adjacent to the overflow opening of the sanitary tub. The cover rosette protrudes into the sanitary tub and is rotatably and movable mounted in the housing, the connecting device being connected to the cover rosette for remotely operating the bottom valve In an overflow device with a continuous level regulator for a sanitary bathtub.

  The bottom valve of the sanitary tub can be activated by turning the cover rosette. Furthermore, the overflow device has an adjusting means for continuously changing the maximum possible water level in the sanitary tub.

  An overflow device having the above features and functions is known from US Pat. In the known arrangement, the cover rosette is not only rotatably and movably mounted, but is also adjustable in the axial direction of the axis of rotation between the two functional positions. The cover rosette includes a running water channel having an inlet opening that is radially offset with respect to the overflow opening of the sanitary tub, and a running water outlet that is exactly in line with the water collection airspace of the housing.

  In such a functional position, the maximum water injection level of the sanitary tub can be adjusted by rotating the cover rosette. In the second functional position, the cover rosette leaves the sanitary bathtub wall and exposes the overflow opening. In this functional position, a connecting device connected to the cover rosette is connected on the adjusting device to actuate a bottom valve located at the bottom of the sanitary tub. The bottom valve of the sanitary tub can be opened and closed by turning the cover rosette to the second functional position.

Explanation of the operation of the cover rosette is necessary. Disadvantages are that the rotational action of the cover rosette to open and close the bottom valve affects the position of the inlet opening and that the water injection level can only be adjusted after the bottom valve is closed. In addition, this disadvantage makes it difficult to read the adjusted water level, as it must always take into account which functional position the cover rosette is in. Overflow handling needs to be improved throughout.
German Patent Invention No. 4,226,685

  The subject of this invention is providing the overflow apparatus provided with the said function from which a simple operation can be achieved using a continuous water level adjustment apparatus.

The above-mentioned problem starts from an overflow device having the characteristics described at the beginning. According to the present invention, the overflow opening of the sanitary bathtub is tightly enclosed and rotatably mounted on the outer peripheral surface. A cover rosette covering the overflow body, having a flow channel with an inlet opening radially offset with respect to the axis of rotation of the overflow body, and a water flow outlet precisely aligned with the water collection airspace of the housing It is solved by placing it inside.

  Through the gap between the cover rosettes or the opening in the cover rosette, the water flows into the air space surrounded by the cover rosette and flows out through the overflow body inside the cover rosette. In this case, the inlet opening of the overflow body determines the water injection height in the sanitary tub. By turning the overflow body, the position of the inlet opening can be continuously adjusted, and the maximum water injection level in the sanitary bathtub can be adjusted in this way. Independently about it, the bottom valve of the sanitary tub can be opened and closed by rotating the cover rosette. The functions of “opening / closing the bottom valve” and “adjusting the water injection level” are completely separated from each other.

  Suitably, the overflow body has a hand lever that projects through an opening in the cover rosette or through a gap between the cover rosette and the bathtub body.

  It is preferable that the adjustment range of the rotational motion of the overflow body is determined by a restraining member that assigns a lower value and an upper value of the overflow height.

  According to a preferred embodiment of the present invention, the overflow body is configured as a molded body, the molded body having a cylindrical hub and a flowing water channel surrounding the hub, and the flowing water outlet is the overflow body. It is arranged in the area surrounding the hub at the front. Suitably, the inflow opening is arranged on the circumference of the shaped body. According to a preferred embodiment of the invention, the flow channel is open circumferentially with respect to the funnel-shaped body forming the inlet opening.

  The arrangement described below allows the components to be easily assembled and allows the components to be fixed reliably. The housing of the overflow device has an outer casing on the collar that abuts against the outer wall of the sanitary tub, and an inner cylinder spaced from the outer casing to accommodate the clamp bushing. A clamp bushing is inserted in the hub of the overflow body, this clamp bushing is mounted in the inner cylinder of the housing, and for fixing the overflow body in the axial direction with the shaft tube for mounting the cover rosette. Color. The collar cooperates with a shoulder formed on the hub. The cover rosette has a pin that grips through the shaft tube of the clamp bushing, and is rotatably and movably guided in the inner cylinder of the housing at its free end to remotely operate the bottom valve It is connected to the functional member of the device. Further, a ring member is disposed between the housing and the overflow body, and this ring member suitably has an inner ring and an outer ring connected to the cross member, and the outer ring is formed in the overflow opening. It is in contact with the sanitary bathtub on the circumference and forms a sliding and sealing surface for the overflow body. The inner ring cooperates with the clamping surface on the clamping bushing. The housing and ring member can be tightened by turning the clamp bushing toward the bathtub body and thereby secured in place. The collar of the clamp bushing preferably has a stepped stop surface comprising two annular surfaces, the first annular surface forming a clamping surface acting on the ring member and the second annular surface The face cooperates with the overflow body. In this way, the overflow body is fixed in the axial direction between the second annular surface and the front surface of the overflow body, and is guided rotatably and movable.

  The ring member may have a centering sleeve-like portion that extends into the housing.

  In the following, the present invention will be described with reference to the figures showing only one exemplary embodiment.

  The basic structure of the overflow device shown in the figure is a housing 1, a cover rosette 2, and a connecting device 3 connected to the cover rosette for remotely operating a bottom valve (not shown). The housing 1 is attached to the outer wall of the sanitary tub 4 and has a water collecting air space 5 together with a drainage connection 6 adjacent to the overflow opening of the sanitary tub 4. The cover rosette 2 protrudes into the sanitary bathtub 4 and is attached to the housing 1 so as to be rotatable and movable. In an exemplary embodiment, the connecting device 3 for remotely actuating the bottom valve consists of a pinion attached to the free end of the pin-like extension 7 of the cover rosette 2 and cooperates with an adjusting device not shown. This adjusting device is provided in a region 8 of the housing 1 which is separated from the water collection airspace and is connected to the bottom valve, for example via a Bowden cable.

  An overflow body 9 is provided inside the cover rosette 2, and this overflow body firmly seals the overflow opening of the sanitary bathtub 4 on the outer peripheral surface and does not move to the housing 1 or the housing. It is attached to the connected ring member 10 in a twistable manner. The overflow body 9 has a flowing water outlet 11 having an inlet opening 13 that is offset in the radial direction with respect to the rotational axis 12 of the overflow body 9, and a flowing water outlet that is exactly in line with the water collecting air space 5 of the housing 1. 14. Through the gap between the cover rosette 2 and the inner wall of the sanitary tub 4 and through an opening 15 arranged around the cover rosette 2, water flows into the air space sealed by the cover rosette, and It flows out through the inlet opening 13 of the overflow body 9. By twisting the overflow body 9, the height of the inlet opening 13 can always be adjusted, and in this way the maximum water injection level of the sanitary tub can be adjusted. The overflow body 9 is actuated using a hand lever 16 formed on the overflow body 9, and in an exemplary embodiment projects through a gap between the cover rosette and the bathtub body. Furthermore, it is within the scope of the present invention that the hand lever 16 can be connected to the outside of the cover rosette 2 through a slit-like opening in the cover rosette. An adjustment range for the rotational movement of the overflow body 9 is determined by the restraining member 17. The position of the overflow body 9 shown in FIG. 3a indicates the position of “maximum overflow height”. In this case, the inlet opening 13 is above the rotational axis 12 of the overflow body 9. In the functional position shown in FIG. 3 b, the inlet opening 13 is located at the height of the rotational axis 12 and the running water outlet 14. This position defines a low adjustment range.

  The overflow body 9 is configured as a molded body, and this molded body has a cylindrical hub 18 and a flowing water channel 11 surrounding the hub 18. The flowing water outlet 14 is arranged in a region surrounding the hub in front of the overflow body 9. It can be particularly inferred from the drawing of FIG. 1 that the flowing water channel 11 opens on the outer peripheral surface with respect to the funnel-like body forming the inlet opening 13.

  FIG. 2 shows the mounting state of the components in the sanitary bathtub overflow opening. The housing 1 has an outer casing 19 with a collar 20, which abuts against the outer wall of the sanitary bathtub and is spaced from the outer casing to accommodate the seal 20 'and the clamp bushing.
