Abstract

A nut ( 1 ) for securing a sanitary faucet ( 2 ) to a support ( 3 ), comprising:
a base body ( 4 ) with a plurality of threaded lugs ( 5 ), which can be adjusted in a radial direction ( 7 ) when a nut ( 1 ) is pushed onto a thread ( 6 ) of the sanitary faucet ( 2 ), and a twist lock ( 8 ), which can be rotated between a locking position ( 9 ) and a release position ( 10 ) and which is secured to the base body ( 4 ), wherein the twist lock ( 8 ) locks the threaded lugs ( 5 ) in the locking position ( 9 ).

First claim

The invention claimed is:

1 . A nut ( 1 ) for securing a sanitary faucet ( 2 ) to a support ( 3 ), the nut ( 1 ) comprising:
a base body ( 4 ) comprising six threaded lugs ( 5 ), a first longitudinal end ( 25 ), a second longitudinal end ( 30 ), and a handle portion ( 31 ), and a twist lock ( 8 ) secured to the base body ( 4 ), which can be rotated between a locking position ( 9 ) and a release position ( 10 ), wherein the twist lock ( 8 ) locks the six threaded lugs ( 5 ) in the locking position ( 9 ); wherein the handle portion ( 31 ) is a continuous surface of revolution extending from the twist lock ( 8 ) to the second longitudinal end ( 30 ), the sanitary faucet ( 2 ) comprises a thread ( 6 ) and a faucet shaft ( 22 ) having a longitudinal axis ( 24 ), the nut ( 1 ) can be pushed onto the thread ( 6 ) without rotation parallel to the longitudinal axis ( 24 ) of the faucet shaft ( 22 ), and when the nut ( 1 ) is pushed onto the thread ( 6 ), the six threaded lugs ( 5 ) are outwardly adjustable in a radial direction ( 7 ) of the base body ( 4 ).

2 . The nut ( 1 ) according to claim 1 , wherein at least one of the base body ( 4 ) and the twist lock ( 8 ) comprises a glass fiber reinforced plastic.

3 . The nut ( 1 ) according to claim 1 , wherein the nut ( 1 ) is embodied as a two-piece unit.

4 . The nut ( 1 ) according to claim 1 , wherein the base body ( 4 ) further comprises a first length ( 11 ) of at least 40 mm.

5 . The nut ( 1 ) according to claim 1 , wherein the twist lock ( 8 ) comprises a second length ( 12 ) of at least 5 mm.

6 . The nut ( 1 ) according to claim 1 , wherein the twist lock ( 8 ) can be rotated between the locking position ( 9 ) and the release position ( 10 ) by a rotational angle ( 13 ) of 10° to 180°.

7 . The nut ( 1 ) according to claim 1 , wherein the base body ( 4 ) comprises at least one stop ( 14 ), which limits a rotational angle ( 13 ) of the twist lock ( 8 ).

8 . The nut ( 1 ) according to claim 7 , wherein the base body ( 4 ) comprises three stops ( 14 ).

9 . The nut ( 1 ) according to claim 1 , wherein the twist lock ( 8 ) comprises six free spaces ( 15 ), wherein the six threaded lugs ( 5 ) are adjustable in the radial direction ( 7 ) in the release position ( 10 ) of the twist lock ( 8 ).

10 . The nut ( 1 ) according to claim 9 , wherein the six free spaces ( 15 ) have a depth ( 35 ) of at least 1 mm.

11 . The nut ( 1 ) according to claim 1 , wherein the twist lock ( 8 ) is guided on the base body ( 4 ) between a first axial stop ( 16 ) and a second axial stop ( 17 ).

12 . The nut ( 1 ) according to claim 1 , wherein the twist lock ( 8 ) comprises six free spaces ( 15 ), and in the locking position ( 9 ) the six free spaces ( 15 ) are not completely in accord with the six threaded lugs ( 5 ) of the base body ( 4 ).

13 . The nut ( 1 ) according to claim 1 , wherein the twist lock ( 8 ) can be rotated between the locking position ( 9 ) and the release position ( 10 ) by a rotational angle ( 13 ) of 30°.

14 . The nut ( 1 ) according to claim 1 , wherein the base body ( 4 ) further comprises a first length ( 11 ) extending from the first longitudinal end ( 25 ) to the second longitudinal end ( 30 ) along a longitudinal direction ( 27 ), and the twist lock ( 8 ) comprises a second length ( 12 ) extending along the longitudinal direction ( 27 ), and wherein the first length ( 11 ) is longer than the second length ( 12 ).

15 . The nut ( 1 ) according to claim 14 , wherein the first length ( 11 ) is 3 to 8 times longer than the second length ( 12 ).

16 . The nut ( 1 ) according to claim 1 , wherein the handle portion ( 31 ) is a cylinder.
