DE29501360U1 - Support frame for a bathtub or shower tray - Google Patents

Description

The present invention relates to a support frame for a bathtub or shower tray comprising at least one height-adjustable support foot with an adjustment tube which is connected at the upper end to a support element on which the bathtub or shower tray rests, as well as with a threaded tube from which the adjustment tube can be unscrewed, for adjusting the height of the support foot and with a foot element at the lower end of the support foot which rests on the floor.

A support frame of the aforementioned type is known, for example, from DE-PS 34 25 054. The support element on which the tub rests is a beam that extends horizontally under the tub and along the tub and to which the adjustment tube is firmly connected. From the older, unpublished patent application P 44 14 643.4 dated April 27, 1994, a support base for a support frame of the generic type is also known, in which the support element on which the tub rests is a bracket that is connected to the adjustment tube in the lower area and is firmly connected to the tub wall by welding in the upper area where the tub wall rests on the bracket. These support elements in the previously known support frames do not offer the possibility of adaptation to tubs of different shapes and sizes or with different radii along the tub wall in the support area.

The object of the present invention is therefore to create a support frame for a bathtub or shower tray of the type mentioned at the beginning, in which an adaptation to differently shaped bathtubs with different radii in the course of the tub wall and a use for different tub sizes is possible.

The solution to this problem is provided by a support frame for a bathtub or shower tray of the type mentioned above with the characterizing features of the main claim.

A further alternative solution to the inventive task is provided by a support frame for a bathtub or shower tray, in which the height-adjustable support foot has a support element that is connected at the upper end to a support element on which the bathtub or shower tray rests and the height-adjustable support foot has a threaded element that is connected to the lower end of the support element and can be unscrewed from the support element for adjusting the height of the support foot, wherein the support foot has a foot element at its lower end that rests on the floor, with the characterizing features of claim 14. In this alternative variant of the invention, the structure of the elements of the support foot for the height adjustment is somewhat different from the variant according to claim 1, in that the support element takes the place of the adjustment tube and a threaded element takes the place of the threaded tube, which can be a screw or a threaded tube that is screwed into the lower section of the support element provided with a thread corresponding to the threaded element. can be screwed in. However, these parts of the support base are analogous to those of the first variant of the invention and the solution according to the invention, which is provided by the support elements with their shape adapted to the course of the wall of the tub, on which the tub wall rests or rests loosely in two support areas, is also provided in this second variant.

According to the invention, brackets are provided as support elements, the shape of which is adapted to the course of the wall of the tub, but only two support areas are provided, so that the brackets can be used for tubs with different radii in the course of the tub wall.

are. In addition, the tub only rests loosely on the brackets in the support areas. The tub is held in place on the support frame by using two brackets arranged in mirror image, on which the tub base rests in a first support area and on which the tub wall rests in a second area, which are clamped against each other by a clamping device.

In addition, a connection is preferably provided between the bracket and the tub by using retaining tabs that can be attached to the brackets at their lower end and that can be detachably attached to the tub at their upper end, e.g. by using bolts welded to the tub into which these retaining tabs can be hooked. For this purpose, the retaining tabs can each have a keyhole at their upper end that engages over the head of a bolt welded to the tub with the shaft. These retaining tabs are preferably thin, flexible sheet metal strips so that they can be bent up to be hooked into the welded bolts.

To compensate for different radii along the tub wall, an approximately chair-shaped form of the bracket is preferred with a horizontal section that rests on top of the adjustment tube, a lower support area for the tub floor and an upper contact area for the tub wall, in which the bracket runs very steeply, e.g. at an angle of 65° to 80° to the horizontal. The aforementioned chair shape is therefore the result of this steep section, which can run in a slightly S-shaped curve, which is then followed by the horizontal section that rests on top of the adjustment tube and which is then followed by a part that is angled approximately vertically downwards, in the area of which the

• at

-4 clamping device is attached.

A tensioning device can be used, for example, as a turnbuckle with two threaded rods, one end of which can be inserted through holes in the downward-angled part of the bracket and secured there with nuts or similar. However, a hose clamp, a sheet with a quick release, a chain tensioner or similar can also be used. 10

The adjustment unit for the height adjustment of the support base made of threaded tube and adjustment tube usually has a sufficient adjustment range. However, if a larger adjustment range is required, then according to a further development of the invention an adapter is proposed which can be screwed to the threaded tube on the one hand and to the adjustment tube on the other hand, which is thus arranged between the threaded tube and the adjustment tube and thus increases the adjustment range.
20

Foot elements can be used that can be inserted into the lower end of the threaded tube and have a hole in the middle to enable attachment to the floor, e.g. with nails or screws. There can be a loose connection between these foot elements and the lower end of the threaded tube, so that the inclination of the foot element can be adjusted and unevenness of the floor can be compensated for. By tilting the feet on the bathtub, greater stability can be achieved. The pads arranged between the tub and the bracket in the contact area prevent noise from the tub from being transmitted to the floor via the support feet. Because the support brackets used are made of a flexible material (e.g. thin sheet metal or plastic), there is a minimal possible range of movement of the support feet in relation to the tub, which means that if handled improperly,

··♦♦ *·

-5-Damage to the enamel on the tub can be prevented.

The base element can, for example, be designed as a pendulum plate with a concave ball socket on the top, which interacts with a corresponding spherical shell-shaped base part of the threaded tube when adjusting the inclination of the support base. Furthermore, the base element preferably has elastic locking webs so that it can be connected to the lower end of the threaded tube via these locking webs.

In the support or contact areas, support pads can be used which have, for example, molded locking elements with an undercut on the underside and can therefore be snapped into holes in the brackets. These support pads preferably have a small radius and are adapted to the shape of the brackets in the support or contact areas of the tub.

To connect the brackets to the upper end of the adjustment tube, the brackets can have cylindrical sockets with an internal thread in their horizontal section, into which the upper end of the adjustment tube can be screwed. The subclaims 2 to 13 relate to preferred developments of the first alternative of the solution to the problem according to the invention.

If the second alternative solution to the problem of the invention is chosen, then the support element can have a lower tubular section with an internal thread, which is followed at the top by a section inclined to the vertical, which is firmly connected at its upper end to the underside of the bracket. Preferably, the support element forms a partial tubular casing in its upper section, which is thus open on one side and enables the threaded element to be screwed in to adjust the height of the support foot. This

The solution variant has the advantage in terms of manufacturing technology that the support element can be bent from one piece in such a way that it forms a pipe casing that gradually closes from top to bottom and forms a pipe, with the lower section forming a complete pipe into which an internal thread is cut. The support element is therefore widest at the top and forms a good support for the bracket. Because the threaded section in the lower part of the support element, into which the threaded element, e.g. a screw, is screwed, is vertical, while the upper part of the support element, which is connected to the bracket, is slightly inclined to the vertical, the foot element is eccentrically outwards when viewed from the connection area between the support element and the bracket, i.e. the area in which the support forces are introduced, which results in better lateral support for the tub.

If a carriage bolt is used as the threaded element, its head can be snapped into the upper recess of the foot element, whereby the foot element is preferably made of an elastic plastic. The upper end of the tubular jacket-shaped upper section of the support element can be welded to the underside of the bracket.

Subclaims 15 to 19 relate to preferred developments of the second variant of the solution to the problem according to the invention. Subclaim 20 relates to an alternative variant of the connection between the retaining tab and the underside of the tub. Instead of hanging the retaining tab over the head of a bolt welded to the tub, the retaining tab can also be connected to the retaining bracket on its underside and the retaining tab can be connected in its upper section to the underside of the tub via an adhesive point.

First, reference is made to Fig. 1. The illustration shows a support frame according to the invention on which a bathtub 20 rests. This support frame is height-adjustable. The support frame generally comprises four support feet, each of which is arranged in the corners of a rectangle under the tub. Each height-adjustable support foot consists of a lower threaded tube 5 with an internal thread, which is provided with a foot element 7 at the lower end, and an adjustment tube 6 that can be unscrewed from the lower threaded tube 5. The part with the reference number 6, which is referred to here as the "adjustment tube", can instead just as well be a threaded rod. The "threaded tube" with an internal thread designated by reference number 5 is an adjustment nut made of plastic or steel. A bracket 1 is attached to the upper end of the adjustment tube 6, on which the bathtub 20 rests. As indicated in the drawing, an additional bracket la is provided, which is arranged in a mirror image of the bracket 1. As a rule, a total of four support feet and four brackets are provided. The brackets each have a lower vertical bend la, to which a threaded rod 11 of a clamping device is fixed.

-XO-

Either a threaded rod 11 with two nuts or a turnbuckle or quick-release fastener can be used as a clamping device. This clamping device 11 can be used to clamp two brackets 1 against each other so that they press against the tub on the right and left. Between the bracket 1 and the tub 20, there are pads 3, 4 made of a soft material, e.g. plastic. The connection between each bracket 1 and the associated wall section of the tub 20 is made using a retaining tab 2, which can be hooked into a welded bolt 10 that is firmly connected to the tub 20.

The invention is explained further below using more detailed drawings of the individual parts of the support frame. Reference is first made to Figures 2 to 5, in which the bracket 1 is shown.

The bracket 1, which can be a sheet metal part that is produced by punching and bending, is shown in the cut before the bending process in Fig. 5. The bracket has a punched-out section and is bent up to form a kind of cylindrical socket Ib. (See Fig. 2 and Fig. 4). The right-hand part of the bracket in the drawing Fig. 5 is angled downwards by 90° to the angled part la, which can be seen in Figs. 1 and 4. In addition, the bracket has two elongated beads lc that are arranged parallel in the longitudinal direction. These beads lc protrude slightly downwards, as can be seen in Fig. 4. The angled part la has a hole Id in the middle for the passage of the threaded rod 11 of the clamping device. The bracket 1 is bent in such a way that it takes on a chair-like shape, as can be seen in Fig. 4. The left part If beyond the cylindrical nozzle Ib is angled upwards by 90° from the plane of the bracket, while the right part la is angled downwards by 90° from the plane.

-11-

•♦··

In between, the largely horizontal section Ii, in which the beads lc are located, runs in the longitudinal direction of the bracket. This horizontal section Ie of the bracket is connected to the height-adjustable adjustment tube 6 of the support base via the socket Ib with internal thread. A lock nut 9 is used to secure it. A further lock nut 12 is provided to secure the adjustment tube 6 in the respective pull-out position on the lower threaded tube 5.

From Fig. 5 it can be seen that the sheet metal blank of the holding part 1 has two recesses lh in the left area. The recess lh is adjoined to the right by a leg Ig of the

*5 bracket. This leg Ig is bent downwards out of the plane of the horizontal section Ie (see Fig. 4) and is used to attach the retaining tabs 2, which are each attached to the leg Ig from above, whereby the connection of the bracket 1 to the bathtub 20 is established via the retaining tabs 2. (See Fig. 1). The width of these retaining tabs corresponds approximately to the width of the legs Ig. The retaining tabs are shown again on an enlarged scale in Fig. 6. As can be seen, they each have a keyhole 2a at one end so that they can be hooked into the weld bolts 10 with this keyhole. These weld bolts 10 are shown again on an enlarged scale in Fig. 7. As can be seen, these weld bolts have a shaft 10a connected to the bathtub and a thickened screw-like head 10b. The keyhole 2a of the retaining bracket 2 can therefore be anchored to this head 10b of the weld-on bolt 10 when it is attached to the trough 20. The fastening of the retaining brackets 2 to the holding brackets 1 can be done, for example, by riveting, stretching or welding. The retaining bracket 2 initially takes a flatter, slanted position and then

-12-

its free end with the keyhole 2a is bent up and attached to the weld bolt 10, so that the steeper incline shown in Fig. is obtained. The other end of the retaining tab 2 is then attached to the leg Ig of the retaining bracket

° attached.

Reference is made below to Fig. 8a to 8c. These show the support cushions 3, which are attached to the brackets in the area of the bent sections If and on which the bathtub 20 is supported, whereby the support cushions 3 rest laterally in the area of the radius of the bathtub 2 0, while the support cushions 4 (see Fig. 1) lie under the horizontal section of the bathtub 2 0. The support cushions 4 are constructed in a similar way to the support cushions 3, the former are usually just a little narrower and are therefore not described further. The support cushions 3 have locking elements 3a with an undercut molded in pairs underneath them, so that they can be locked into holes Ii in the brackets (see Fig. 4) and thus attached to the brackets 1. In cross-section, the support pads 3 are rounded with a slight radius, as can be seen from Fig. 8c, so that they adapt to the slightly rounded shape of the brackets in the area of the holes Ii and rest against them. As can be seen from Figs. 8a and 8b, the support pad is approximately rectangular in outline, with three spaced locking elements 3a provided along the length. Overall, the support pad 3 is relatively flat, as can be seen from the side view. If necessary, the support pad can also be made shorter with only two locking elements 3a.

The holes Ik are provided for fastening the support pads 4.

Figures 9a and 9b show the threaded tube 5, which has an internal thread 5b in the upper section and a spherical shell-shaped, rounded inward

'-IS-

curved foot part 5a, so that the threaded tube 5 can be arranged at an angle, as can be seen from Fig. 1. The lower end of the threaded tube interacts with the foot element 7 shown in Fig. 10a and 10b. This foot element is designed as a so-called pendulum plate. The foot element 7 has a concave ball socket 7a on the top, which interacts with the correspondingly shaped spherical shell-shaped foot part 5a of the threaded tube 5. The lower base surface 7b of the foot element 7, on the other hand, is flat. The foot element 7 tapers from bottom to top in a trapezoidal manner. An anchoring part 7c is formed in the middle of the top of the foot element 7, which has three elastic locking webs 7d that extend radially outwards and are free at the ends, by means of which the foot part 7 can be connected to the lower end of the threaded tube 5. This connection is made in such a way that when the foot part 7 is pressed in, the springy legs 7d of the anchoring element snap behind the inner surface of part 5a of the threaded bolt. The three webs 7 each have a chamfer 7e at the end. This makes it easier for the foot element 7 to snap into the threaded tube from below. In addition, the threaded tube 5 can pivot relative to the foot element 7 on the ball socket-like surface 7a, so that the threaded tube 5 can be brought into a position inclined to the vertical as shown in Fig. 1 in order to improve the pressure of the bracket 1 laterally against the bathtub 20 and thus the support function of the support foot as a whole.

As can be easily seen from Fig. 1, the height adjustment of the individual support foot is achieved by loosening the lock nut 12 and then turning the threaded tube 5 as an adjustment nut, whereby the inner adjustment tube 6 is moved out of the threaded tube 5 by the desired distance.

is unscrewed.

Due to the special geometry of the bracket 1 and the retaining lugs 2, the support frame according to the invention is suitable for holding bathtubs 20 with different radii. The weld-on bolt 10 used for attaching the retaining lug 2° has the advantage that it is only low in height, so that bathtubs can be stacked one inside the other if necessary. The clamping of two mirror-image brackets 1 against each other so that they press against the bathtub wall with the support cushions 3 on the right and left, respectively, is done by means of the clamping device consisting of the threaded rod 11, which is screwed through the angled sections la of the bracket, whereby

Two nuts 19 are used for the respective clamping position. 15

A second variant of a support frame according to the invention for a bathtub or shower tray is described in detail below with reference to Figs. 11 to 17b. Similar to the variant described above, there is again a support frame on which the bathtub rests. The support frame again comprises four support feet, two of which can be braced against each other. Each support foot is height-adjustable. The support foot is constructed somewhat differently here and comprises a support element 35, which is tubular in a lower section 35a with an internal thread 35b into which the thread of a lock screw 36 engages. The support element 35 is inclined to the vertical in its upper section 35c, so that the foot element 37 lies next to the vertical projection of the upper connection point between the support element 35 and the bracket 1 in the standing plane, which results in better lateral support of the tub. The tubular support element in the lower section 35a opens above the internal thread 35b, so that in the upper section 35c, which is connected to the bracket 1, only a partial pipe jacket

is present, which also folds out further towards the top and thus widens. In Fig. 16a to 16c, the support element 35 is shown again in detail.

A locking nut 31 is provided below the section 35a of the support element 35. The head 36a of the carriage screw 36 is received by the foot element 37. The foot element 37 is made of a sufficiently elastic plastic so that the head ^36a of the carriage screw can snap into place behind the locking projection 7a from above. The foot element 37 is shown again in detail in an enlarged manner in Fig. 17a, 17b.

The bracket and clamping device are in principle similar in the embodiment according to Fig. 11

constructed like that according to Fig. 1. Only the area in which the connection between the bracket 1 and the support element 35 is made is different in the bracket 1 here. The upper end of the section 35c of the support element ² ^ 35 is welded to the underside of the bracket 1.

The bracket itself, which is used in this variant of the invention, is shown in detail again in three views in Figs. 12, 13 and 14 and is referred to there as bracket 1' since it differs somewhat from the ² ^ bracket shown in Figs. 2, 3 and 4.

A third variant of the present invention is shown in Fig. 15. A comparison of the representation with that according to Fig. 11 shows that the basic structure of the

The support base is the same here. A support element 35 is also provided, which is welded to the underside of the bracket I ^1. The tubular part 35a with internal thread 35b of the support element 3 5 takes up the thread of the carriage bolt 3 6. By unscrewing or

³ ^ Screwing in the lock screw after loosening the lock nut 31, the height can be adjusted.

• · · &bgr;

Foot element 37 also corresponds to that of the variant according to Fig. 11. The bracket 1' and clamping device 11, 19 are also basically constructed in the same way. However, the connection between the retaining tab 2' and the underside of the bathtub 20 is different here. In this variant of the invention, the weld bolt 10 is omitted. Instead, the retaining tab 2' is glued to the underside of the tub via an adhesive point 32. The gluing is preferably carried out at several points or in a flat area in which the retaining tab 2' corresponds to the shape of the tub given by the radius of the bathtub 20.

These glued retaining tabs 2' can also be used in the variant of the support foot according to the invention according to Fig. ¹¹ ^.

If the given path for the height adjustment of the individual support foot according to the invention is not sufficient, an adapter can be used as an intermediate piece, which e.g.

² ^ has an external thread and an internal thread at the top and is connected to both threaded elements 5 and 6 in order to extend the adjustment path. It is also possible, for example, in the variant according to Fig. 11 to use an adapter which is arranged under the foot part 37 so that the latter then stands on the adapter, which also allows the tub to be raised to a greater extent.
