Definitions
- the present invention relates to a nut for fastening a sanitary fitting to a support.
- Sanitary fittings serve in particular to provide a liquid as required in a washbasin, kitchen sink, bathtub and/or shower.
- the carriers regularly have a mounting opening through which the sanitary fittings extend with a fitting shaft.
- the fittings shaft can be designed, for example, as a threaded sleeve.
- a nut is screwed onto the fitting shaft, which nut fastens the sanitary fitting to the support. Due to the length of the fitting shaft, screwing the nut onto the fitting shaft involves a great deal of effort. For example, significantly more than 20 turns can be required to tighten the nut.
- 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 specify a nut with which a sanitary fitting can be fastened with little effort.
- This object is achieved with a nut according to the features of the independent claim.
- Further advantageous configurations of the nut are specified in the dependent claims. It should be pointed out that the features listed individually in the dependent patent claims can be combined with one another in any technologically meaningful way and define further refinements of the invention. In addition, the features specified in the patent claims are specified and explained in more detail in the description, with further preferred configurations of the invention being presented. Contributing to this is a nut for fastening a sanitary fitting to a support, which nut has at least the following:
- a base body with a plurality of threaded tabs which can be adjusted in a radial direction when the nut is pushed onto a thread of the sanitary fitting
- a twist lock which is rotatably attached to the base body between a locking position and a release position, the twist lock being in the Locking position locks the threaded lugs.
- the (multi-part) nut is designed in particular in the manner of a screw nut and/or can be screwed onto an (external) thread about a longitudinal axis or axis of rotation of the nut.
- the nut has a base body with a plurality of threaded lugs.
- the base body can be tubular and/or have a round cross section.
- the base body can extend along the longitudinal axis or axis of rotation of the nut and/or have a straight course.
- the base body can consist at least partially of plastic and/or metal.
- the threaded tabs are designed in particular in the manner of thread flanks or tongues.
- the threaded lugs on the base body can be designed to be bendable.
- an internal thread of the base body can be formed on the threaded lugs.
- the nut has a twist lock which is fastened to the base body in a rotatable manner relative to the base body.
- the screw cap can in particular be rotatably attached to a surface of the base body circumferential surface. Furthermore, the screw cap can be ring-shaped. In addition, the screw cap can consist at least partially of plastic and/or metal.
- the twist lock can be rotated, in particular limited, between a locking position and a release position. In the release position of the screw cap, the threaded tabs are released, so that when the sanitary fitting is fastened to a carrier, which can be a (work)top, for example, the nut is pushed onto a fitting shaft designed as a threaded sleeve, for example Sanitary fitting is enabled.
- the threaded tabs When pushed onto the fittings shaft, the threaded tabs can be bent or adjusted outwards by the thread of the fitting shaft in a radial direction, ie orthogonally to the longitudinal axis or axis of rotation of the nut. This means that the nut does not have to be screwed over the entire length of the fitting shaft.
- the twist lock When an underside of the carrier is reached, the twist lock can be rotated relative to the base body into the locking position, so that the threaded lugs are locked.
- Locking can be understood in particular as meaning that the threaded tabs are fixed in such a way that the internal thread of the base body is no longer in an axial direction of the nut, i.e.
- the base body or the screw cap can consist at least partially of glass fiber reinforced plastic.
- the base body and/or the screw cap can consist at least partially of glass fiber reinforced plastic.
- the nut can be made in two parts. In particular, this can mean that the nut consists of only two parts, namely the base body and the screw cap.
- the base body can have a first length of at least 40 mm (millimeters).
- the first length can be 40 mm to 120 mm.
- the first length is measured, in particular, parallel to the longitudinal axis or axis of rotation of the nut.
- the twist lock can have a second length of at least 5 mm.
- the screw cap can preferably have a second length of 5 mm to 40 mm, particularly preferably 25 mm to 10 mm.
- the second length is measured in particular parallel to the longitudinal axis or axis of rotation of the nut.
- the twist lock can be rotated between the locking position and the release position by an angle of rotation of 10° to 180°.
- the rotating closure can preferably be rotated between the locking position and the release position by an angle of rotation of 10 to 90°, particularly preferably (substantially) 30°.
- the base body can have at least one stop, which limits a rotation angle of the rotary closure.
- the at least one stop can extend outwards in the radial direction, for example. Furthermore, the at least one stop can, for example, contact a first stop surface of the rotary fastener in the locking position and/or contact a second stop surface of the rotary fastener in the release position.
- the twist lock can have a plurality of free spaces into which the threaded tabs can be adjusted in the radial direction when the twist lock is in the released position.
- the free spaces can be designed, for example, in the manner of recesses or grooves.
- the free spaces can be formed in particular on an inner surface of the rotary fastener and/or can extend through the rotary fastener in the radial direction.
- the free spaces can have a depth of at least 1 mm.
- the free spaces can preferably have a depth of 1 mm to 10 mm, particularly preferably 1 mm to 5 mm. The depth is measured in particular in the radial direction of the nut, in particular starting from the inner surface of the twist lock.
- the twist lock can be guided on the base body between a first axial stop and a second axial stop.
- the first axial stop and/or the second axial stop can in particular extend outwards in the radial direction from a peripheral surface of the base body.
- the first axial stop can be formed on a first longitudinal end of the base body.
- the second axial stop can be designed in such a way, or be so small in the radial direction, that the twist-lock fastener can be pushed by elastic deformation of the twist-lock fastener and/or the second axial stop from a second longitudinal end of the base body in the axial direction to the first axial stop Body is attachable. As a result, the screw cap can be fastened to the base body with little effort.
- Fig. 1 a fixed with a nut on a carrier sanitary fitting in a side view; 2: the nut in a perspective representation;
- Fig. S the nut in a first sectional view along one shown in FIG
- FIG. 4 the nut in a second sectional view along a section line IV-IV shown in FIG. 3;
- FIG. 5 the nut in a third sectional view along one shown in FIG
- FIG. 6 the nut in a fourth sectional representation along a section line VI-VI shown in FIG.
- FIG. 1 shows a side view of a sanitary fitting 2 fastened to a support S with a nut 1 .
- the sanitary fitting 2 has a fitting housing 18 with a pivotable outlet 19 . On the outlet 19 there is an outlet opening 20 through which the sanitary fitting 2 can deliver liquid to an environment 21 .
- the sanitary fitting 2 is inserted with a fitting shaft 22 having a thread 6 through an assembly opening 23 of the carrier 3 and fastened to the carrier 3 with the nut 1 .
- a twist lock 8 of the nut 1 was turned into a release position 10 shown in Fig. 3 and the nut 1 was then pushed along its longitudinal axis 24 onto the fitting shaft 22 until a first longitudinal end 25 of the nut 1 was on an underside 26 of the Carrier 3 plant. Then the screw cap 8 was adjusted into a locking position 9 shown in FIG.
- the (multi-part) nut 1 or nut arrangement comprises a base body 4 and the twist lock 8 which is rotatably attached to the base body 4 .
- the base body 4 is tubular and extends along the longitudinal axis 24 from the first longitudinal end 25 to a second longitudinal end 30. Furthermore, the base body 4 has a first length 11 along the longitudinal axis 27 and the rotary fastener 8 has a second length 12.
- the base body 4 includes in the region of the screw cap 8 a plurality of threaded tabs 5, on which an internal thread 28 of the base body 4 is formed.
- the threaded lugs 5 extend parallel to the longitudinal axis 24 in a longitudinal direction 27 , with a projecting end 29 of the threaded lugs 5 being oriented in the direction of the second longitudinal end 30 of the base body 4 .
- the Screw cap 8 is here in a release position 10, in which the threaded tabs 5 when the nut 1 is pushed onto the fitting shaft 22 of the sanitary fitting 2 shown in FIG are adjustable or bendable on the outside.
- the nut 1 can be slid onto the fitting shaft 22 parallel to the longitudinal axis 24 without any rotary movement.
- the base body 4 comprises a grip area 31 which extends from the twist lock 8 to the second longitudinal end 30 and has a third length 32 parallel to the longitudinal axis 27 .
- FIG. 3 shows the nut 1 in a first sectional illustration along a section line III-III shown in FIG.
- the base body 4 in the variant embodiment of the nut 1 shown here has six threaded lugs 5 which are evenly distributed in a circumferential direction 33 of the nut 1 .
- the rotating closure 8 is here in the release position 10, in which the free spaces 15 in the radial direction 7 with the threaded fasteners 5 cover.
- the threaded lugs 5 can be adjusted outwards in the radial direction 7 into the free spaces 15 of the rotary fastener 8 .
- FIG. 4 shows the nut 1 in a second sectional view along a line IV-IV shown in FIG. 3.
- FIG. The free space 15 has a depth 35 starting from an inner surface 34 of the rotary closure 8 in the radial direction 7 to the outside.
- FIG. 5 shows the nut 1 in a third sectional view along a section line V-V shown in FIG.
- the base body 4 has three stops 14 which extend outwards in the radial direction 7 .
- the rotary fastener 8 in FIG. 5 was counterclockwise relative to the base body 4 with a
- Angle of rotation 13 is adjusted or rotated into a locking position 9 until the first stop surfaces 36 of the rotary fastener 8 contact the stops 14 of the base body 4, so that the screw cap 8 relative to the base body 4 can no longer be rotated counterclockwise.
- the free spaces 15 of the screw cap 8 do not (completely) coincide in the radial direction 7 with the threaded lugs 5 of the base body 4.
- the threaded lugs 5 are locked so that they cannot be adjusted outwards in the radial direction 7.
- the rotary fastener 8 can be adjusted clockwise relative to the base body 4 with the angle of rotation 13 back into the release position 10 shown in FIG. so that the rotary fastener 8 relative to the base body 4 is no longer rotatable clockwise.
- FIG. 6 shows the nut 1 in a fourth sectional view along a section line VI-VI shown in FIG. It can be seen in FIG. 6 that an outer surface 38 of the threaded lugs 5 of the base body 4 rests directly on the inner surface 34 of the screw cap 8 so that the threaded lugs 5 cannot be adjusted outwards in the radial direction 7 . As a result, the internal thread 28 of the base body 4 cannot slip over the thread 6 of the fitting shaft 22 shown in FIG. 1, but is in engagement with the thread 6 . In this way, the nut 1 can be tightened on the fitting shaft 22 by rotating it about the longitudinal axis 24 shown in FIG.
- the rotary fastener 8 is guided on the base body 4 between a first axial stop 16 and a second axial stop 17, so that the rotary fastener 8 can move in an axial direction 40, i. h parallel to the longitudinal axis 24 of the base body 4 shown in FIG. 2, cannot be detached from the base body 4.
- the axial stops 16, 17 extend from a peripheral surface 39 of the base body 4 in the radial direction 7 to the outside.
- the first axial stop 16 is formed on the first longitudinal end 25 of the basic body 4 .
- the second axial stop 17 is designed in such a way or is designed so small in the radial direction 7 that the rotary fastener 8 can be detached from the second longitudinal end 30 shown in Fig.
