Description

The invention relates to a foot bearing for height adjustable Support feet one Support frame for Bathtubs and shower trays, each support leg rotatable on the foot support is arranged.

Such a foot camp is for example in the DE 34 25 054 A1 described by the applicant. This prior art has the advantage that the foot bearing remains at rest while the threaded sleeve is being adjusted relative to the ground. There are therefore no displacements of the tub already aligned in the horizontal plane. There is also an advantage in that noises from water flowing into the tub can be transmitted to the underground and into adjacent rooms in a significantly reduced manner.

In connection with the increased Noise insulation requirements however this solution, which is advantageous in itself, is in need of improvement with regard to the Sound decoupling seen from bathtubs or shower trays.

In addition, from the DE 42 43 709 C1 a height-adjustable support foot for bath or shower tray support frames is known, in which the height-adjustable support foot is characterized by a disc-shaped slide bearing which engages under the threaded sleeve and is supported on a bearing housing, the bearing housing carrying a central projection which is rotatably overlapped by a central opening of the threaded sleeve , As described above, this pivot bearing is also seen as in need of improvement.

From the JP 2000107059A a foot arrangement with a damping device for vibrations is known, but not every support foot is rotatably arranged on the foot bearing here. It is therefore difficult to adjust the height of the already installed tub, because the tub base cannot be rotated under load. The damping mechanism is also formed by a foamed spring, which means that the manufacture of the damping mechanism is relatively complex.

The object of the invention is therefore in it, starting from the footrest described first further reduction in sound transmission while maintaining the advantages of a pivot bearing.

The solution to this problem results itself from the feature of claim 1, in particular the features the label part, according to which the foot bearing in the area of one Groundbreaking foot floor area at least partially with at least one insulation element for reduction the sound transmission is provided, through which the foot bearing is spaced from a surface.

The foot bearing according to the invention has the essential Advantage that simple How a significantly reduced sound transmission is achieved. In particular when training the foot camp as a cap with a bottom and a circumferential side wall the insulation element be well integrated into the well-known construction.

The floor area can be a From at least one insulation element Completely be covered or the insulation element even over the floor area protrude itself.

In a preferred embodiment the invention is beyond the insulation element arranged in at least one depression of the floor surface.

This has the advantage that the insulation element at Load pickup at least partially receives an immediate lateral support. Also is it possible that insulating element to be secured within a depression by clamping.

In another embodiment The invention is (are) the depression (s) in the bottom surface of a bottom clamping edge and an adjoining, a distance from the insulation element having supporting edge surround. So while the bottom edge of the clamp the clamp of the insulation element allows becomes when the insulation element is loaded a side flow of the material of the insulation element up to a supporting edge possible then through the supporting edge the insulation element is stabilized.

It is also possible that the at least one Countersink has the shape of a ring in which a likewise annular insulating element is arranged. This embodiment has the advantage of lower material costs in terms of insulating element with consistently high sound decoupling.

Ultimately, it goes one step further one embodiment, at the bottom of the foot camp a central opening has and on the bottom surface facing the opening of an annular insulating element is surrounded. This also results in material savings in the area of the foot camp.

In the preferred embodiment According to the invention, the at least one insulating element consists of polyether urethane. This special polyurethane material is a cellular elastomer used in various technical applications is used for vibration decoupling. Both in print and These materials also have good insulation properties under shear loads on. The advantage of this material is that: depending on the type of application and the load on the selection of the density, Shaping and the contact surface can customize.

Ultimately, this applies to all of the aforementioned embodiments not just the possibility the clamp, but in addition it is also conceivable that an adhesive attachment can take place.

Further advantages of the invention result from the following description of several exemplary embodiments. Show it

1 a support frame for bathtubs or shower trays in a perspective view,

2 a support foot according to 1 in exploded view,

3 a support foot according to 2 when assembled,

4 2 shows a sectional illustration through a threaded sleeve arranged in the foot bearing,

5 another embodiment of a footrest with insulating element in a sectional view,

6 a further embodiment of a foot bearing with insulation element in a sectional view and

7 a further embodiment of a foot bearing with a ring-shaped insulation element in a sectional view.

In the drawings, a support frame for bathtubs or shower trays is overall with the reference number 10 designated.

The support frame 10 has a central rivet plate 11 and four articulated arms at the ends 12 on, on each arm 12 as well as on the rivet plate 11 one height-adjustable support leg each 13 is arranged.

In the 2 and 3 is the support foot 13 shown. Starting from the arm 12 there is the support foot 13 from a threaded rod 14 , a sheet metal nut 15 , a lock nut 16 , a threaded sleeve 17 , a double threaded sleeve 18 as well as a cap-shaped foot bearing 19 ,

In the 4 you can see the arrangement of the footrest in the sectional view 19 on the threaded sleeve 17 very clearly. The foot camp 19 has a bottom B and a circumferential side wall S, which with an inside circumferential rib 20 is provided, which is also in an annular recess 21 the threaded sleeve 17 intervenes.

In addition, the bottom of the foot camp 19 with a dip 22 in a floor area 23 provided, in the clamp and / or adhesive fastened an insulation element 24 is preferably made of polyether urethane.

When assembled, it can be used to align the height of a support frame 10 for example, a shower tray, not shown, the threaded sleeve 17 a support leg 13 be twisted. The threaded sleeve 17 leads a relative movement in relation to the foot bearing 19 from which, however, remains at rest in relation to the underground. The foot camp 19 thus has the function of a pivot bearing, the plastic material of the foot bearing 19 has favorable sliding properties for these reasons. When the support foot is loaded 13 springs the insulation element 24 slightly a. For this reason, the depth T of a depression 22/25 is chosen so that the insulation element 24 , which has a thickness D of about 5 mm, at least 1.5 mm from the bottom surface 23 protrudes. This is necessary because of the base on which a support frame 10 a bathtub or shower tray is arranged, always has a certain roughness and thus contact of the footrest 19 is reliably prevented with the subsurface.

In the 5 you can see that in the floor area 23 a different shaped depression 25 is available, which is provided with a step extension. This sinking 25 has a clamping area 26 and an expansion area 27 with a support edge 28 on. When lifting the support leg 13 and thus also the insulation element 24 cushions this a small amount, the material laterally in the expansion area 27 flows and on the surrounding support edge 28 Stops. On the one hand, a certain deflection is facilitated and on the other hand a certain support function is achieved.

In the 6 is basically shown that the insulation element 24 of course also over the floor area 23 of the foot camp 19 can protrude.

Ultimately, in the 7 a further embodiment of a foot camp 19 shown at the bottom B of the foot camp 19 a central opening 29 has which of an annular depression 30 is surrounded, in which an annular insulating element 31 is arranged.
