The support elements have an additional section which is telescopic and includes the attachments section.

Description

The invention relates to a support device in the preamble of claim 1 or 17th Specified genus and a support element for such a support device.

Support devices of this type are used in the care of the elderly, the sick and the disabled used especially in the shower and toilet area. They are intended for the user of the Provide sanitary door means that he can use when using the Sanitary seat can support comfortably, and at the same time before falling after the Protect to the side and to the front, which is why the support element is firmly in the secured position Support device is locked. In addition, the side grab handles at in Support position located the transfer from or to a wheelchair enable.

In a known support device of the type mentioned at the outset, the support element is with its one end swiveling towards one of the handles attached that it by simple pivoting movements between the secured position and the release position swung back and forth and its other end in the secured position with the help of a locking device in the form of a ball catch firmly with the other handle can be connected. The advantage of easy positioning of the However, the support element faces the problem that in most cases it is narrow space is not always the necessary space to do this To pivot the support element out of the securing position into the release position, that access to the sanitary seat is completely free even for wheelchair users or the No access to other facilities through the pivoted support element is hindered. In addition, such support elements cannot be used in conjunction with Use grab handles in the form of support arms (e.g. DE 31 50 765 C2) that Serve purpose between a position of use in which they are substantially vertical and protrude from the wall or the like in a horizontal position and a non-use position, in which they are essentially parallel to the wall or the like and vertical are arranged, can be pivoted back and forth to thereby still one allow unhindered access to the sanitary seat. In such a case, it should known support element namely pivoted together with the support folding handles and to be moved over the user's head, which is undesirable and to Risk of injury.

In contrast, the present invention seeks to support the the genre described at the outset in such a way that they neither provide free access to the sanitary seat complicates the training of the handles as support handles prevented.

The characteristic features of claims 1, 17 serve to solve this problem and 20.

The invention has the advantage that the support element is a separate component represents that which is detached from the rest of the support device and stored separately from it, if necessary, however, by means of the U-shaped fastening sections and the locking means can be firmly connected to the handles.

Further advantageous features of the invention emerge from the subclaims.

1 to 3 show a support device according to the invention for a not shown Sanitary seat. The support device contains two parallel to each other and at a distance Arranged handles 1, or the like on one side of the sanitary seat on a wall. be attached. The fastening parts intended for fastening to the wall are not shown. The handles 1 are essentially in their use position perpendicular from the wall and run essentially horizontally at a height of e.g. 800 mm above the floor at a distance of e.g. 700 mm from each other. in the Embodiment, the handles 1 consist only of tubular or rod-shaped Components, although they are actually preferably in the manner of known support folding handles (DE 31 50 765 C2) are formed.

The support device according to FIGS. 1 to 3 also has an anti-tip device in the form of a Support element 2, e.g. essentially of a board-like, in a central section component 3 provided with a support cushion 4. The support element 2 is also formed as a component separate from the handles 1 and points to it a fastening section 5 or 6 on both ends. The fastening sections 5,6 are formed or arranged mirror-symmetrically to one another in the exemplary embodiment and U-shaped curved so that when the support member 2 is transverse to the longitudinal axes of the handles 1 is placed on these, each grip a handle 1 in a U-shape can, as shown in particular in FIG. 2.

As will be explained in more detail below, the support element 2 preferably contains at least one telescopically displaceable part which has one of the fastening sections 5, 6 and which can be displaced in FIGS. 1 and 2 in the direction of an arrow v relative to the remaining part of the support element 2. This makes it possible to increase or decrease the length of the support element 2 in order either to adapt to different distances between the two handles 1 and / or to facilitate the assembly of the support element 2.

The fastening section 5 contains a leg 7 rigidly connected to the support element 2 and a leg 8 pivotably connected to it, both of which are curved approximately in accordance with one half of the U-shape and are pivotally connected to one another by means of a pivot pin 9, the pivot axis of which is perpendicular to the direction of the Arrow v or the longitudinal axis of the support element 2 extends. The pivotability of the leg 8 that is possible as a result is indicated in FIG. 2 by an arrow w . The pivot axis of the legs 8 lies in the assembled state of the support element 2 essentially parallel to the axes of the handles 1.

The fastening section 6 is designed accordingly. The only difference between the two fastening sections 5,6 is that they are each mirror-symmetrical towards the inside of the support element 2 curved in a U-shape, i.e. with their open Sides facing each other.

To produce the securing position shown in FIGS. 1 to 3, the support element 2 is first pulled apart in the direction of the arrow v and then with the fastening sections 5, 6 facing downward and in a position essentially perpendicular to the handles 1 from above onto the front ends the rod-shaped handles 1 placed. The support element 2 is then pushed together again in the direction of the arrow v , with the two fastening sections 5, 6 approaching, until the fastening sections 5, 6 slide onto an associated handle 1 from the outside and accommodate this between them. If necessary, the respective leg 8 can be pivoted back and forth in the direction of arrow w .

The support element 2 is now fixed transversely to the handles 1 on this, whereby the The space between them is essentially blocked and a sanitary seat is used Can support person on the support element 2. The support element also prevents 2 in this position that the person using the sanitary seat unintentionally after from tilting while holding the handles 1 tilting to the side prevent. If the person wants to leave the sanitary seat again, these are described Steps performed in the opposite order until the mounting sections 5.6 are removed from the handles 1. The support element 2 can now by the Handles 1 are lifted and placed in a suitable place. It is then in a release position that allows free access to the sanitary seat.

So that there is no danger that the support element 2 in the secured position 1 and 2 unintentionally and relative to the handles 1 moves or even from slips it, at least one locking means is assigned to it, which in the exemplary embodiment 1 to 3 serves the fastening sections 5,6 in their illustrated, the handles 1 lock in a U-shaped clamping position and immovable to fix them. An example locking means that the is assigned pivotable leg 8, will be explained in more detail below with reference to FIGS. 4 and 5 explained.

4 and 5 show only the left in Fig. 2 mounting portion 5, since the right Fastening section 6 is designed accordingly and therefore not also described are needed. Thereafter, the leg 7 consists of a bent according to FIG. 2 End portion of an insert 11 made of steel or other metal, the e.g. the component 3 (Fig. 1 to 3) forms, at its one free end with the central portion a shaft 12 extending transversely to its longitudinal direction is welded and parallel to this on both sides of the weld seams has a free space in one hollow cylindrical plastic sleeve 13 surrounding the shaft 12 at a radial distance is used coaxially, which extends in the axial direction only over part of the shaft 12 extends. In the open receiving ends of the sleeve 13 are from both sides successively one helical spring 14 and one ring-shaped, first locking element 15 mounted on the shaft 12. The locking element 15 is on its outer end face an end toothing 16 (see also FIG. 4). The locking element 15 is on the Shaft 12 is axially displaceable but non-rotatably supported by, for example, as shown in Fig. 4, the Shaft 12 has a non-circular outer cross section and the locking element 15 accordingly non-circular inner cross section.

On the shaft 12 is also a hollow cylindrical second from both sides Latching element 17 pulled up, each at the free end of a half 8a, 8b in its Middle plane 18 (Fig. 5) divided leg 8 is attached and on its spur gear 16 facing side is also provided with end teeth 19. The Locking element 17 has a slightly larger internal cross section than the shaft 12 and is seated rotatable on a release lever 20, which after the springs 14 and the Locking elements 15, 17 on the shaft 12 from the outside into the annular cavity is inserted between the shaft 12 and the second locking element 17 until it with its inner end face rests on the first locking element 15. At its outer end the unlocking lever 20 has an actuating button 21 designed as a hollow body with a mounting flange 22, which serves as a stop shoulder for a snap ring 23, which is clipped onto the shaft 12 for the axial fixation of the entire arrangement. The unlocking lever 20 expediently has an outer cross section of the shaft 12 corresponding inner cross section and a cylindrical outer cross section on the one hand he himself axially displaceable but non-rotatably mounted on the shaft 12 and on the other hand, the second locking element 17 is rotatably arranged on it. Otherwise it is second locking element 17 expediently as an insert of the associated plastic manufactured half 8a, 8b formed where the actuating head 21 to lie comes with a guide sleeve 24, in which the operating button 21 axially is guided. The halves 8a, 8b and the connected to them made of metal locking elements 17 preferably as well as the sleeve 13 and that connected with it, consisting of metal insert 11 as plastic injection molded parts manufactured.

To assemble the arrangement described, the springs 14, the first locking elements 15 and the second locking elements 17 with the associated guide sleeves 24 drawn from both sides onto the shaft 12. Then be the release levers 20 inserted until their actuating buttons 21 in the guide sleeves 24 lie, whereupon the snap rings 23 are snapped onto the shaft 12. Finally, the actuating buttons 21 are each closed with a cover cap 25. The various parts are designed and dimensioned such that the spur gears 16,19 now by the axial bias of the springs 14 against each other pressed and are therefore in engagement with one another to form a locking means, whereby the halves 8a, 8b and thus the entire leg 8 non-rotatably on the support element 2 are locked. In contrast, it is possible to release the lock in that the Both release levers 20 are pressed axially inwards. This will make the first locking elements 15 against the force of the springs 14 also radially inwards moved so that the two spur gears 16, 19 now about a pivot axis 26 the shaft 12 can be rotated relative to each other, which is the schematic in Fig. 2 indicated pivot pin 9 forms. After release of the operating buttons 21 the respective swivel position is automatically locked again.

In an alternative embodiment, the spur gears 16, 19 are designed such that the pivotable legs 8 are pivoted in one direction can that one spur gear 19 the other spur gear 16 against the Spring force can overflow. Such an arrangement facilitates e.g. making the respective locking position, whereas unlocking here only with the help the unlocking lever 20 is possible.

To avoid that the two legs 8a, 8b unintentionally to the side of the shaft 12 can be deducted, e.g. possible to close them in the area of their abutting surfaces glue and connect by a screw, not shown, the parting line interspersed and arranged parallel to the axis 26.

In the exemplary embodiment according to FIGS. 7 to 9, a support element 28 is provided which has a support cushion 30 carried by a component 29. The component 29 has a tubular section 29a which is fixedly connected to the support pad 30 and a section 29b which is guided telescopically in the section 29a and in the support tube 30. The two sections 29a, 29b can be displaced relative to one another parallel to a double arrow x and during assembly transversely to two handles 31 arranged and designed in accordance with FIGS. 1 to 6. Each section 29a, 29b has at its free end a U-shaped fastening section 32, 33, both of which are essentially identical, but mirror-symmetrically oriented and face one another with their open sides, so that only the fastening section 32 is described below. The fastening section 32 has two legs 34, 35 corresponding to the legs 7, 8 according to FIGS. 1 to 6, but rigidly connected to one another, which are preferably arranged at a distance from one another corresponding to the diameter of the handle 31 to be clamped, so that they can take this with little play between them. According to a particularly preferred variant of this embodiment, at least one of the legs, here the leg 35, is provided with at least two differently shaped sections 35a, 35b in such a way that the two legs 34, 35 are closer in the vicinity of their connection point than at their distant ends exhibit. As a result, the legs 34, 35 according to FIGS. 8 and 9 can hold at least two handles 31, 36 with different diameters firmly and largely without play. If the two legs 34, 35 are straight and are connected in a wedge shape to form an acute angle, handles with many different diameters can be inserted into them.

In this embodiment, the locking means consists of a clamping screw 38 (FIG. 7), which is only indicated schematically, is provided with an actuating button 37 and is accessible through the support pad 30, by means of which the distance between the two fastening sections 32, 33 parallel to the arrow x can be fixed . The assembly of the support element 28 is therefore carried out by first placing it on the handles 31, 36 in the extended state of the sections 29a, 29b in such a way that the fastening sections 32, 33 are each arranged outside of them. Then the parts 29a, 29b are telescopically pushed together and braced against one another in such a way that the handles 31, 36 according to FIGS. 8 and 9 are gripped by the fastening sections 32, 33 in a U-shape and firmly clamped between them. Finally, the clamping screw 38 is tightened, as a result of which the support element 28 is largely immovably fixed on the handles 31, 36. The clamping screw 38 can alternatively also be displaced by a clamping element biased by a spring or by any other locking element.

A particularly preferred and very easy to handle embodiment of the invention is shown in FIGS. 10 to 24. A support element 40 here contains a load-bearing, tubular insert 42, which is overmolded with a support cushion 41 made of polyurethane foam or the like and which, for example, consists of a flat oval aluminum tube and has a longitudinal axis 43 (FIG. 11). At the ends of this insert part 42, a flat oval guide sleeve 44a, 44b is inserted into the insert part 42, which serves to receive and guide a sliding part 45a, 45b. Both sliding parts 45a, 45b each have a cross section corresponding to the inside diameter of the guide sleeves 44a, 44b in a section intended for arrangement in the guide sleeve 44a, 44b, while their sections protruding from the guide sleeves 44a, 44b each have a fastening section 46 or 47 are provided. The sliding part 45b is axially immovably fixed in the support element 40 by means of a clamping screw 48 which projects through a threaded bore formed in the insert part 42 and / or the guide sleeve 44b, the clamping screw 48 being accessible through the support pad 41 or also covered by it and by any other fastening means can be replaced. In contrast, the other sliding part 45a is mounted in the guide sleeve 44a between two positions defined by end stops 49, 50 (cf. also FIG. 15) so that it can move freely in the direction of a double arrow y . The end stops 49, 50 are realized, for example, by the boundary walls at the ends of a groove 51, which is formed in a direction parallel to the longitudinal axis 43 (arrow y ) in the circumferential surface of the sliding part 45a and into which an or arranged in the jacket of the guide sleeve 44a formed stop part 52 in the form of a fastening screw, indentation or pull-in nut, a spring bolt or the like protrudes, which can also be accessible through the support pad 42 or covered by this. Alternatively, of course, the sliding part 44a could also be rigidly fixed in the guide sleeve 44b and instead the sliding part 45b could be slidably mounted. A displaceable mounting of both sliding parts 45a, 45b is also possible. In any case, the axial displaceability of at least one sliding part 45a, 45b serves the purpose of being able to pull the support element 40 axially apart in the sense of the above description to the extent required for its assembly to arrange the two fastening sections 46, 47 on the outer sides of assigned handles is.

The two fastening sections 46, 47 are mirror-symmetrical analogous to FIGS. 1 to 9 arranged and with their open sides facing each other. Since they are also largely are identical, only the fastening section 46 is explained in more detail below.

13 to 16, the slide member 45a includes a metal one Insert 54, which is encapsulated with a plastic layer 55 and at one end with a 90 ° bent, rigidly attached to him leg 56 is provided on his free end has a portion 56a (Fig. 14, 16) which is slightly less wide than corresponds to the width of the sliding part 45a. The leg 56 has 56a in this section a cylindrical passage 57 running transverse to the longitudinal axis 43 (FIGS. 11, 15) on the two axial ends with a cylindrical extension 58 is provided. This extension 58 is, as shown in particular in FIG. 13, with a axially continuous radial slot 59 provided. The sliding part 45a is expedient made of a plastic injection molded part, and the sliding part 45b is expediently identical educated.

17 to 20 show a pivotable connection with the leg 56 of FIG. 13 to 16 existing, pivotable and in its function the leg 8 of FIG. 2nd and 4 to 6 corresponding legs 60. The leg 60 is on its one, for Connection with the leg 56 certain end formed in a U-shape as a whole. He there has two spaced-apart, lateral webs 61, 62 and one these connecting, middle web 63. The two side webs 61, 62 are each with provided with a passage 64, both of which are arranged coaxially with one another and, as in particular Fig. 19 shows, at their inner, mutually facing ends with a Section 64a which forms shoulder 65 and has a reduced cross section. Of the Distance between the webs 61, 62 corresponds to the width of the section 56a of the leg 56. Am the other end of the leg 60 is also substantially U-shaped according to FIG. 17 educated. There he has two side by side facing each other Crosspieces 66, 67 which are connected to one another by a central crosspiece 68 parallel to the crosspiece 63 connected and according to FIGS. 18 and 20, each with an inwardly open receiving opening 69 are provided, which in the exemplary embodiment have a square cross section having.

As particularly shown in FIGS. 18 to 20, sections 64a of the passages adjoin 64 outwardly coaxial central sections 64b with non-circular, e.g. square Cross sections on, while outermost portions 64c of the passages 64 per se can be shaped arbitrarily and preferably slightly larger cross-sections than that Have sections 64b.

21 to 24 show the two legs 56 and 60 according to FIGS. 13 to 16 and 17 to 20, respectively in its assembled, pivotally connected state. Here is the Section 56a of the leg 56 in this way between the two webs 61, 62 of the leg 60 arranged that the axes of the passages 57 and 64 coaxial with a pivot axis 71 are arranged. The passages 57, 64 are also by a pivot pin or a shaft 72 protrudes through a cylindrical and in the passage 57 arranged middle section, which also extends into the corresponding cylindrical portions 64b extends. The outer ends 72a of the shaft 72 each protrude a passage of an associated block 73, which in the central portion 64 of the Corresponding passage 64 of the leg 60 is used, one of the inner cross section of the central section 64b has the corresponding outer cross section and therefore is rotatably held to the leg 60 in the passage 64. The ends 72a of the Shafts 72 are, as shown in particular in FIGS. 22 to 24, in opposite directions Side-mounted flats 72b formed out of round, and the passages of the blocks 73 are provided with corresponding internal cross sections, so that the ends 72a are non-rotatable to the blocks are included in these. Instead of the flats 72b could also square or rectangular cross sections can be provided. As a result, the shaft is 72 overall rotatably mounted in the leg 56, but non-rotatably in the leg 60.

In each of the extensions 58 of the passages 57 of the section 56a of the leg 56 there is a spiral spring 74 surrounding the central section of the shaft 72 (FIGS. 21 to 24). This has two angled ends 74a, 74b, the end 74a being arranged in the slot 59 of an associated extension 58 and the other end 74b in a groove machined into the outer circumferential surface of the shaft 72, which groove expediently extends over the entire length of the shaft 72 extends and runs parallel to the pivot axis 71 (FIG. 21). The coil springs 74 are biased so that the leg 60 is biased in the direction of an arrow z (FIG. 22) and therefore has the tendency to lie against the leg 56 under the force of the springs 74. In a corresponding manner, the sliding part 47 is provided with a pivotable leg 75 (FIG. 11). Alternatively, it would also be possible to omit one of the two springs 74 and the parts assigned to them.

The assembly of the support element 40 according to Figs. 10 to 24 wildly e.g. as follows:

The sliding part 45a is first provided with the pivotable leg 60 by this with its victories 61, 62 is placed on section 56a so that the Passages 57, 64 are arranged coaxially. Then the springs 74 are so in the Extensions 58 of the passage 57 inserted that their ends 74a in the slots 59th enter. The shaft 72 is then inserted into the passages 57, 64, whereby the leg 60 is pivotable, but essentially immovable radially and axially rigid leg 56 is fixed, while ensuring that the ends 74b of the springs 74 enter the continuous groove of the shaft 52. The shaft 72 will now rotated with a tool to thereby bias springs 74, whereupon first from one side of one of the blocks 73 in an associated central section 64b (Figs. 19, 21) of passage 64 e.g. the web 61 is inserted that he associated shaft end 72a rotatably receives. Then the block 73 in turn is arranged non-rotatably in the middle section 64b, both springs 74 are against turning back secured. In the same way, a corresponding block 73 is now on the other side into the central portion 64b of the passage 64 e.g. of the web 61 introduced. For the axial securing of the connection thus established, a snap ring is appropriate 76 used, which is pressed into a circumferential groove, each in one of the associated Block 73 is formed outwardly projecting part of the shaft end 72a. Finally, one passes onto the outer ends of the sections 64c of the passages 64 Cover cap 77 (Fig. 21) clipped on. Alternatively, the cover caps 77 can also be used axially defining the shaft 72 are used, in which case the snap rings 76 can be omitted. Accordingly, the leg 75 (FIG. 11) on the sliding part 45b assembled.

The sliding parts 45a, 45b are now in the manner shown in FIGS. 10 and 11 in the insert 42 or the guide sleeve 44a, 44b inserted, on the one hand the Clamping screw 48 tightened in a preselected axial position of the sliding part 45b and on the other hand the stop part 52 or the like so deep into the groove 51 of the sliding part 45a is introduced that this can be moved axially back and forth in the insert 42 until one of the stops 50, 51 strikes the stop part 52. The possible axial extreme positions 46a and 46b of the fastening section 46 of the sliding part 45a are indicated in Fig. 11 by dash-dotted lines.

To assemble the finished support element 40, it is sufficient to pull the sliding part 45a telescopically out of the insert part 42, then place the supporting element 40 on the handles (for example 78 in FIG. 23) in the manner described and then push the sliding part 45a back into the insert part 42 until both handles 78 are encompassed by the fastening sections 46 and 47 in a U-shape. In order to ensure a safe insertion of the handles 78, the pivotable legs 60, 75 can be pivoted outward against the force of the springs 74, ie against the direction of the arrow z in FIG. 22, until the handles 78 reach the position according to FIG. 23 have reached, and then pivoted back under the action of the springs 74 serving here as locking means. The size of the spring force determines the clamping force with which the handles 78 are clamped between the legs 56, 60. In this embodiment, too, it is possible to adapt to different diameters of the handles, as shown in FIG. 24 for an enlarged handle 79, in which case only the springs 74 in the clamped position are expanded further than in FIG. 23.

The pivotable legs 60, 75 are at their free ends according to FIGS. 22 to 24 expediently with rollers 80 (cf. also FIG. 25) made from a pliable and good to the Handles 78, 79 of adhesive material, e.g. Silicone rubber, provided and on an off Metal insert 81, in the form of a square tube, attached or sprayed on, their length measured in the longitudinal direction essentially the distance of the Crosspieces 66, 67 of the legs 60 correspond. For the assembly of these rollers 80 e.g. a Compression spring 82 and then from both sides a square pin 83 in the insert 81st introduced that under the action of the compression spring 82 with its free end something the insert 81 protrudes. The assembly is done simply by the square pins 83 fully pushed back into the insert 81 and the roller 80 accordingly Fig. 25 is inserted between the webs 66, 67 of the leg 60 until the square pins 83 automatically into the associated receiving openings 69 of the webs 66, 67 (FIGS. 17 to 20) snap into place. Correspondingly, the legs 8 according to FIGS. 1 to 5 could be formed become.

Finally, it is advantageous to provide the legs 56, 60 with a respective one on their inner sides anti-slip, e.g. layer 84 also made of silicone rubber or the like (Fig. 22 to 24) to be provided, which in the clamping position of the legs 56, 60 to the Handles 78, 79 creates and the support member 40 largely immovable on this orders. With corresponding layers 84, the fastening sections 5, 6 could or 32, 33 according to FIGS. 1 to 9.

26 to 28 show the support device according to the invention in its entirety in Connection with the support member 28 of FIGS. 7 and 9 in the assembled state. How 27 can be seen in particular, the support device surrounds one only schematically indicated sanitary seat 86. It also has two according to FIGS. 27 and 28 to the side Completion of the seating area one each to be attached to a wall 87 or the like Handle 88 on that shown in FIG. 28 between one with solid lines horizontal use position, in which it is substantially perpendicular to wall 87 stands, and a dashed dotted vertical non-use position 88a back and forth can be pivoted in which it is substantially parallel to the wall 87th is arranged. The pivotable mounting is carried out with the help of pivot bearings 89, e.g. consist of two spaced plates, between which one on Handle 88 attached sleeve 90 (Fig. 27) is rotatably mounted, the axis of rotation in assembled state is usually horizontal. Otherwise, the handles 88 preferably from two superposed, tubular or rod-shaped Elements 91 and 92 (Fig. 28), which are bent at one end by a U-shaped Element are interconnected and have two free ends, of which the one (upper end) carries the sleeve 90, while the other (lower) end 93 serves the relevant handle 88 in its use position with its lower area to support the wall 87 or the like.

Grab handles 88 of this type, which are also referred to as support folding handles, are Generally known to those skilled in the art (DE 31 50 765 C2, DE 32 38 889 C2) and therefore need them not explained in more detail.

As shown in FIGS. 26 to 28 in particular, the upper tube or rod-shaped elements 91 of the analogous to Fig. 1 to 25 assembly of the Support member 28 at the front ends of the handles 88, although of course it is it would be possible to connect the support element 28 to the lower elements 92.

26 to 29 is also on its back with a back support 94 which e.g. a rod-shaped or tubular, across the width of the seat area includes extended support element 95, in the central part of which a conventional one and is attached to any shaped back cushion 96.

The support element 95 is bent at the two lateral ends by 90 ° to the rear End portions 97 provided, as shown in FIG. 29 on flat, annular end faces ends that are expedient in a common plane and at the ends of in the End portions 97 attached, blind hole-like receiving openings 98 are located in rear part e.g. Have cylindrical internal cross sections and to the End faces are provided with an extension 98a. In addition, the End portions 97 each have a through bore extending through the receiving opening 98 99 on.

For the common fastening of the support element 95 and a handle 88 to each According to the invention, wall 87 serves in each case one mounting plate 100, of which the one in FIG Fig. 26 left mounting plate 100 is explained in more detail. The right mounting plate in Fig. 26 100 is appropriately identical. The mounting plate 100 contains according to FIG. 29 a metal, in particular steel insert 101, which is in a plastic sheath 102 is embedded. At the front and preferably in an upper part of it is 29 not visible pivot bearing 89 attached by welding or the like .. Below of the pivot bearing 89, the mounting plate 100 has a support surface 100a (Fig. 28) on which the free end 93 of the handle 88 can be supported.

On a e.g. The mounting plate is located above the pivot bearing 89 100 a through screw hole, through which a usual fastening screw 103 screwed into a wall hole or a dowel fastened in this can be.

For fastening the associated end section 97 of the support element 95 to the wall 87 a stud 104 (FIG. 3), which has an externally threaded section 105 and in its extension has a fastening section 106 which is coaxial with it and which is provided with a transverse bore 107 and has an outer cross section which in essentially corresponds to the inner cross section of the receiving opening 98. Between in both sections 105, 106 the stud 104 is e.g. trained as a hexagon Stop element 108 provided, the outer cross section larger than the outer cross sections of sections 105, 106. Preferably, sections 105, 106 and the like Stop element 108 made in one piece, but could for example also be provided to form the stop element 108 as a nut and this firmly on the Unscrew the external thread section 105 and, if necessary, weld it to it.

The mounting plate 100 is preferably on a below the pivot bearing 89 and in particular between this and the support surface 100a with a passage 109 provided, whose inner cross section is slightly larger than the outer cross section of the Male thread portion 105 of the stud 104 is. The arrangement is like this met that the external thread section 105 is inserted through the passage 109 and in screwed in a wall hole so deeply formed or a dowel fitted in it can until the stop element 108 to the front of the mounting plate 100 created. When the stud 104 is further tightened by means of a to the stop element 108 attached tool, the mounting plate 100 is then firmly between the wall 87 and the stop element 108 clamped. As a result, the stud is used 104 on the one hand as a fastening means for the mounting plate 100.

On the other hand, the stud bolt 104 also serves as a fastening means for the support element 95. The attachment of the support member 95 takes place after the attachment of the Mounting plate 100 by screwing in the fastening screw 103 and the stud bolt 104 in that the receiving opening 98 of the end portion 97 on the fastening portion 106 of the stud bolt 104 is inserted until the two transverse bores 99, 107 are aligned with one another, the extension 98a being the stop element 108 takes up, whereupon a locking pin 110 is inserted into the transverse bores 99, 107 and thereby the connection of the parts 95, 106 is established.

According to a particularly preferred embodiment of the invention, the mounting plate 100 is assigned a cover cap 111, which is used to carry out the threaded section 105 specific hole and is otherwise closed all around. The cover cap 111 becomes e.g. after by tightening the mounting screw 103 and the stud 104 the mounting plate 100 is mounted on this and by means of Snap connections or the like. Set on this. In this case, both the End face of the end portion 97 of the support member 95 and the free end 93 of Elements 92 expediently from the front of the cap 111.

An advantage of the cap 111 is that it is visually appealing Allows appearance and the mounting plate 100 including the mounting screw 103 covers. Further, since the passage 109 is completely covered by the end portion 97, there is a fastening, of which at most the locking pin 110 is visible, if this is not covered by a cover flap 112 inserted into the bore 99. There is also the advantage that the entire support device with mounting plates 100 is mountable, which is not larger than the usual folding support handles for mounting mounting plates used. The right end portion of the support member 95 in FIG. 26 can be attached to the wall 87 with a corresponding mounting plate 100.

A particular advantage of the support device described with reference to FIGS. 26 to 29 consists in the fact that they are manufactured, packaged, transported and in stock as a complete unit can be held and assembled. For mounting the support device including the Support element 28 and the back support 94 are only the two mounting plates 100 required so that the assembly with a small number of wall holes and Fasteners can be carried out. Nevertheless, the handles 88 can also be used as Support folding handles are formed without thereby handling the support element 28 and / or the backrest 94 or the accessibility to the sanitary seat 86 essential is hindered. It goes without saying that the backrest 94 in an analogous manner also then can be provided if simple, rigid with the mounting plates 100 as handles connected rods or tubes according to FIGS. 1 to 25 used and / or instead of Support element 28, the other support elements described above are provided.

The invention is not restricted to the exemplary embodiments described, which can be modified in many ways. This applies in particular to the type and design of the various support elements and the back support. If necessary, it is possible to use both the back support 94 without the handles 88 and vice versa, the handles 88 without the back support 94, the presence of the pivot bearings 89 not being particularly disruptive in the former case, while in the latter case for fastening of the mounting plate 100, instead of the stud 104, a second fastening screw 103 and a cover cap could also be used, which also covers the second fastening screw. Furthermore, the support element is not limited to embodiments in which the fastening sections are pushed onto the handles from the two outer sides thereof. In particular, it would also be possible, for example, to attach the fastening sections 5, 6 according to FIG. 2 to the component 3 such that they are open perpendicular to the direction of the arrow v and can therefore be pushed onto the handles 1 from above, for example perpendicular to the arrow v . With this arrangement, both the various means proposed for adapting to different diameters and / or cross-sectional shapes of the handles as well as the means proposed for telescopic extension or shortening of the support elements and serving to adapt to different distances between the handles can be used analogously. In addition, instead of tubular or rod-shaped handles, those with other cross-sectional shapes could also be provided. Finally, it goes without saying that the features of the various embodiments can also be used in combinations other than those described and illustrated in the drawings.
