Abstract

The bearing (19) for height-adjustable support feet of bath-tubs and shower trays comprises an insulating element (24) which serves for reduction of sound transmission and leaves a gap between the base surface (23) of the bearing and the floor.

Description

The invention relates to a foot bearing for a height-adjustable support feet Support frame for bathtubs and shower trays, with each support foot on the Foot bearing is rotatably arranged.

Such a foot bearing is for example in DE 34 25 054 Applicant described. This prior art has the advantage that Foot bearing while understanding the threaded sleeve against the ground remains at rest. So there will be no shifts in the Horizontally aligned tub caused. There is also an advantage in that noise from water flowing into the tub is significantly reduced can be transferred into the underground and into adjacent rooms.

In connection with the increased demands on the However, noise insulation is considered to be this advantageous solution in need of improvement with regard to the sound decoupling of bathing or Seen shower trays.  

In addition, from DE 42 43 709 a height-adjustable support foot for Bath or shower tray carrier known, where the height adjustable Support foot through a disc-shaped slide bearing, which is the threaded sleeve engages and is supported on a bearing housing, is characterized, the Bearing housing carries a central projection that from a central opening of the Threaded sleeve is rotatably gripped. This pivot bearing is also as above described as in need of improvement.

The object of the invention is therefore based on that foot bearings first described a further reduction in sound transmission while maintaining the advantages of a pivot bearing.

The solution to this problem results from the feature of claim 1. in particular the features of the identification part, according to which the foot camp in Area of a floor surface pointing away from the foot at least partially with at least one insulation element to reduce sound transmission is provided, by which the foot bearing is spaced from an underground is arranged.

The foot bearing according to the invention has the essential advantage that on a significantly reduced sound transmission can be achieved in a simple manner. Particularly when the footrest is designed as a cap with a bottom and a circumferential side wall, the insulation element can well into the known Construction to be integrated.

The bottom surface of a footrest can be at least one Insulation element to be completely covered or the insulation element even over the Protrude floor area itself.

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

This has the advantage that the insulation element at least when the load is picked up partially receives immediate lateral support. It is also possible that Fasten the insulation element within a depression by clamping.

In a further embodiment of the invention, the Sink (s) in the bottom surface of a bottom clamping edge and an adjoining one, at a distance from the insulation element Surround the supporting edge. So while the bottom clamping edge Clamping of the insulation element allows, when the load is taken up Insulation element a lateral flow of the material of the insulation element up to a supporting edge possible, the insulating element then through the supporting edge is stabilized.

It is also possible that the at least one depression has the shape of a Has ring, in which a likewise annular insulating element is arranged. This embodiment has the advantage of lower material costs with regard to the insulation element with consistently high sound decoupling on.

Finally, an embodiment goes one step further, in which the floor of the footrest has a central opening and at the bottom facing floor area, the opening of an annular insulating element is surrounded. This also results in material savings in the area of Step bearing.

In the preferred embodiment of the invention there is at least one insulation element made of polyether urethane. With this particular Polyurethane material is a cellular elastomer, which in various technical applications for vibration decoupling is used. These show both under pressure and shear loads Good insulation properties. The advantage of this material is also in that depending on the type of application and the load on the  Selection of the density, shape and the contact area individually can adjust.

Ultimately, not only applies to all of the aforementioned embodiments Possibility of clamping, 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 embodiments. Show it

In the drawings, a support frame for bathtubs or shower trays is designated as a whole by reference number 10 .

The support frame 10 has a central rivet plate 11 and four arms 12 arranged at the ends in an articulated manner, a height-adjustable support foot 13 being arranged on each arm 12 and on the rivet plate 11 .

In FIGS. 2 and 3, the support leg 13 is illustrated. Starting from the arm 12 , the support leg 13 consists of a threaded rod 14 , a sheet metal nut 15 , a lock nut 16 , a threaded sleeve 17 , a double threaded sleeve 18 and a cap-shaped foot bearing 19 .

In FIG. 4, it is very seen in the sectional view of the arrangement of the step bearing 19 on the threaded sleeve 17 clear. The foot bearing 19 has a bottom B and a circumferential side wall S, which is provided with a circumferential rib 20 on the inside, which engages in a likewise annular recess 21 in the threaded sleeve 17 .

In addition, the bottom of the footrest 19 is provided with a depression 22 in a bottom surface 23 , in which an insulating element 24, preferably made of polyether urethane, is arranged in a clamped and / or adhesive manner.

In the assembled state, the threaded sleeve 17 of a support leg 13 can be rotated to align the height of a support frame 10, for example a shower tray (not shown). The threaded sleeve 17 executes a relative movement with respect to the foot bearing 19 , which, however, remains at rest with respect to the underground. The foot bearing 19 thus has the function of a pivot bearing, the plastic material of the foot bearing 19 having favorable sliding properties for these reasons. When the support foot 13 is loaded, the insulation element 24 deflects slightly. For this reason, the depth T is a depression 22/25 chosen so that the insulation element 24, which has a thickness D of about 5 mm, at least 1.5 mm protruding from the bottom surface of the 23rd This is necessary because the base on which a support frame 10 of a bath or shower tray is arranged always has a certain roughness and thus contact of the foot bearing 19 with the base is reliably prevented.

In Fig. 5 it can be seen that a differently shaped depression 25 is present in the bottom surface 23 , which is provided with a step extension. This depression 25 has a clamping area 26 and an expansion area 27 with a support edge 28 . When the support foot 13 and thus also the insulating element 24 are loaded, this deflects a small amount, the material flowing laterally into the extension area 27 and being held on the circumferential support edge 28 . On the one hand, a certain deflection is facilitated and on the other hand a certain support function is achieved.

In Fig. 6 is shown in a basic manner that the insulating element 24 can of course also protrude beyond the bottom surface 23 of the foot bearing 19 .

Finally, another embodiment of a foot bearing 19 is shown in FIG. 7, in which the bottom B of the foot bearing 19 has a central opening 29 which is surrounded by an annular depression 30 , in which an annular insulating element 31 is arranged.
