Flush mounted built-in body for a sanitary fitting with an axially adjustable push button

Abstract

A flush mounted built-in body for a sanitary fitting, having a mixer with a regulating nut, wherein the regulating nut can be rotated about a rotational axis, a support plate having a hub, a stop ring having a stop supported by the hub of the support plate, and a rotating knob for actuating the mixer. A rotational movement of the rotating knob is limited by the stop of the stop ring and the rotating knob comprises a hollow shaft which couples the rotating knob in a non-rotating manner to the regulating nut and can be adjusted parallel to the rotational axis of the regulating nut.

Claims

1. A flush-mounted body for a sanitary fitting, comprising: a mixer with a regulating nut that is rotatable about an axis of rotation; a support plate with a hub; a stop ring with a stop, the stop ring being carried by the hub of the support plate; and a rotary knob to control the mixer, wherein a rotational movement of the rotary knob is limited by the stop of the stop ring, and wherein the rotary knob has a hollow shaft via which the rotary knob is non-rotatably coupled to the regulating nut and is adjustable in parallel with the axis of rotation of the regulating nut.

2. The flush-mounted body according to claim 1, wherein the regulating nut has a first groove toothing and the hollow shaft has a second groove toothing, and wherein the hollow shaft is in engagement with the second groove toothing of the regulating nut via the first groove toothing.

3. The flush-mounted body according to claim 1, wherein the hollow shaft is non-rotatably connected to the rotary knob.

4. The flush-mounted body according to claim 3, wherein the hollow shaft has a third groove toothing via which the hollow shaft is connected to the rotary knob.

5. The flush-mounted body according to claim 1, wherein the hollow shaft is positioned in parallel with the axis of rotation via a knob cap of the rotary knob.

6. The flush-mounted body according to claim 1, wherein the rotary knob has a button that cooperates with a push of a button of the stop ring.

7. The flush-mounted body according to claim 1, wherein the rotary knob is fastened by a locking ring on the hub.

8. The flush-mounted body according to claim 1, wherein the hub is fastened to the support plate via a screw connection or clamp connection.

9. The flush-mounted body according to claim 1, wherein the stop ring is at least partially concealed by a scale ring.

10. The flush-mounted body according to claim 1, wherein the stop ring is fixed in parallel with the axis of rotation via the rotary knob.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus, are not limitive of the present invention, and wherein:

(2) FIG. 1 is a flush-mounted body in an exploded view;

(3) FIG. 2 shows the flush-mounted body in a deep installation position in the region of a rotary knob; and

(4) FIG. 3 shows the flush-mounted body in a shallow installation position in the region of the rotary knob.

DETAILED DESCRIPTION

(5) FIG. 1 shows a flush-mounted body 1 in an exploded view. The flush-mounted body 1 is substantially cylindrical in shape and has in its interior a mixer 2 designed as a thermostat cartridge with a regulating nut 3. The regulating nut 3 has a first groove toothing 4 on a first outer circumferential surface 25. A support plate 5 with a hub 6 can be fastened on the flush-mounted body 1. The hub 6 is surrounded by a receptacle 19 for a stop ring 7, so that the stop ring 7 is non-rotatably carried by the hub 6. On the stop ring 7, a stop 8 formed in the manner of a drag stop and a stationary push of a button 16 is disposed at a second external circumferential surface 26. The stop ring 7 is at least partially concealed by means of a scale ring 18, so that the stop ring 7 is no longer visible after the rotary knob 9 is installed. The scale ring 18 includes a slide ring 21. The flush-mounted body 1 further comprises a rotary knob 9 fastened to the hub 6 of the support plate by means of a locking ring 17.

(6) The rotary knob 9 has a button 15, which includes a button cap 23 and a button base 20. The button base 20 together with the touch of the button 16 of the stop ring 7 serves to limit a rotation of the rotary knob 9. By pressing the button 15, the push of the button 16 of the stop ring 7 is overridden, so that the rotary knob 9 is rotatable beyond the push of the button 16. The button 15 is held by means of leaf springs 22 on contact surfaces of a slotted slide ring 27 of the rotary knob 9. The slotted slide ring 27 also cooperates with the stop 8 of the stop ring 7 so that the rotation angle of the rotary knob 9 is limited in both directions of rotation. Furthermore, the rotary knob 9 has a hollow shaft 10 with a third groove toothing 13 so that the hollow shaft 10 can be inserted in the rotary knob 9 and can be arranged inside the rotary knob 9, non-rotatable to the rotary knob 9. The hollow shaft 10 is covered by a knob cap 14.

(7) FIG. 2 shows the flush-mounted body 1 in a deep installation position in the area of the rotary knob 9. The hollow shaft 10 has a second groove toothing 11, with which the hollow shaft can be plugged on the first groove toothing 4 of the regulating nut 3 in an axial direction 24 in parallel with a rotation axis 12 of the regulating nut 3 of the mixer 2.

(8) FIG. 3 shows the flush-mounted body 1 in a shallow installation position in the region of the rotary knob 9. In the illustrated shallow installation position of the flush-mounted body 1, the rotary knob 9 with the hollow shaft 10 is pushed completely onto the regulating nut 3.

(9) With the proposed sanitary fitting, a uniform external appearance can be ensured and stop forces or bending moments acting from the rotary knob on the mixer are at least reduced.

(10) The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims
