Description

The invention relates to a device to the end of at least one to a sanitary fitting leading or leading away from it to connect with the sanitary fitting.

There are connection nipples for connecting pipe ends to sanitary fittings known with union nuts or similar can be connected to the sanitary fitting.

The invention is based on the object of being as simple as possible to be carried out fastening arrangement to create with the low Effort from the bottom to connect the cable ends, if necessary, only a single line can.

To achieve this object, the invention proposes a device with the features mentioned in claim 1. Developments of the invention are the subject of dependent claims.
The receptacle for the nipple is usually a cylindrical, possibly interrupted bore. The nipple is secured in the radial direction and the nipple is sealed off from the sanitary fitting by engaging the nipple in the receptacle. The securing means is used for axial securing, so that a nipple inserted into the receptacle can no longer be unintentionally released from the sanitary fitting. The invention makes it possible to push the nipple at the end of the line from the underside of the fitting facing away from the operator to the correct position and then to secure it with the securing device. This provides a very simple way of fastening.

In particular, a further development of the invention can provide that the safety device acts between the valve and the nipple. As a line can not only be a rigid or only to a small extent flexible pipe in question, but also a hose. It makes sense if the safety device between the valve or their housing and the nipple itself.

In a further development of the invention it can be provided that the nipple is held in a holder that can be connected to the fitting is. It is possible that the safety device between the armature or their housing and the bracket works, which of course also a safeguard against pulling out the nipple and thus the Line forms.

According to the invention it can be provided that the holder is an individual Nipple holds. To attach multiple lines could in this If each nipple has its own bracket. It is however also possible and is proposed by the invention, that the holder is provided for at least two nipples. This makes it easier the insertion, since the multiple lines then with a single Handle can be connected to the sanitary fitting.

As a means of securing between the bracket and the sanitary fitting a latching can be provided. The deflectable Element of locking either on the sanitary fitting or on the Bracket may be provided. Of course, it is also conceivable that a deformable or deflectable locking element on both elements is available.

In a further development of the invention it can be provided that the bracket only fixes the at least one nipple axially. For example the nipple can be pushed into the holder from the side be, the radial definition then only by inserting the Nipples in the intake is guaranteed.

The securing means can be attached to the sanitary fitting, for example and / or be attachable. There can also be between the valve body and the bracket.

It can be provided according to the invention that the securing means at least one cooperating with an undercut transversely to Has longitudinal axis of the nipple movable slide. The undercut can both on the nipple and a holder for be provided the nipple.

It can be provided according to the invention that one nipple more than a slide is assigned, for example two diametrically arranged Slide.

The at least one slide mentioned can, for example, be spring-loaded to be moved against the nipple. With that leaves automatic locking may occur if overcome the spring loading by inserting the nipple becomes.

At least one slide can preferably be released manually, that is have training that a user can attack.

But it is also possible that the slide in its fuse effective securing position secured against loosening is.

The securing means or the slide can be moved linearly, for example be trained, what a guide on or in the sanitary fitting can serve.

However, it is also possible for the securing means to be arranged in a rotatable manner is, for example, about an axis parallel to the axis of the sanitary fitting housing.

However, it is also possible and is proposed by the invention that the slide is freely movable, i.e. under spring action or otherwise self-centered without being articulated about a specific axis to be.

It was mentioned that, for example, several sliders on one Can attack nipples. It is also possible and is invented suggested that a slider is present on several Attacks nipples at the same time and fixes them at the same time.

In particular, to move the slide into its release position a key surface can be provided in which a fitter with a commercially available tool can intervene, for example a Screwdriver.

a representation corresponding to Figure 15 in a sanitary fitting with three connection nipples.

Figure 1 shows a very simplified sanitary fitting 1 with a stepped bore 2, which is a receptacle for the upper end of a connection nipple 3 forms. The connection nipple 3 sits at the end of a not shown Line, for example a hose. A short distance away its front end 4, the nipple has a circumferential on its outside Groove 5 to accommodate a seal. This seal seals the connection nipple 3 opposite the bore 2.

The nipple 3 is guided through an opening 6 of a plate 7. The opening 6 is so large that the nipple through the opening 6 from above forth can be used. It lies on the upper side 8 in FIG. 1 the plate 7 with the back 9 of a circumferential flange 10. This back 9 forms an undercut, which the axial securing of Nipples 3 against the plate 7 causes.

The plate 7 has at least two, preferably also more holes on, with which the plate 7 snapped onto locking lugs 11 of the sanitary fitting 1 is. The nipple 3 is together with the plate 7 of the sanitary fitting 1 approximated and with its free end above the Flange 10 inserted into the bore 2. The locking lugs arrive 11 of the sanitary fitting through the holes in the plate 7, so that a Centering and fixing is done. After the locking lugs 11 through the holes of the plate 7 have passed through, they deform again to the outside, so that there is now an axial securing against pulling off is. There can be some play in the axial direction, because the nipple 3 is sufficient due to the seal in the groove 5 is sealed. The recording is designed so that the interior of the nipple 3 with a further bore 12 in connection stands.

What is shown in Figure 1 for a single nipple 3 can of course can also be done for multiple nipples, each on the same plate 7 are attached, so that by inserting several nipples at the same time can be connected to the sanitary fitting 1.

While in the embodiment of Figure 1, the backup by Interaction of the locking lugs 11 via the plate 7 with the nipple 3 done, Figures 2 to 4 show a possibility, such as a bracket 13 with three schematically illustrated nipples 3 bring about axial securing can without the individual nipple 3 completely in the holder 13 can be anchored. The bracket 13, see Figure 2, has three Notches 14, the peripheral shape of which is approximately a semicircle or something correspond to more than one semicircle. The opening of the three notches 14 points radially outwards, the three notches 14 evenly over the Scope are distributed. In the peripheral areas between the notches 14 is a bracket led out of the plane of the notches 14 15 molded on top, that is, towards the sanitary fitting 1, are angled. The three nipples are in the bracket 13 so introduced that the end faces 4 facing away from the bottom 9 of the Flange 10 immediately above the central part of the bracket 13 are arranged. As a result, the three nipples 3 are only axially secured. After pushing the assembly together, the bracket can 13 with the nipples 3 suspended in it upwards into the fitting are inserted, which then looks as shown in Figure 3 is. The radial locking then takes place in that the nipple 3 engage in the respective holes 2. This is shown in Figure 4. Here are also the tops 16 of the free end 4 facing Flanges 10 on the valve. The ends of the brackets have hooks 17, which engage in openings 18 of the sanitary fitting 1 and close there the locking and thus securing the bracket 13 against the Guide sanitary fitting 1.

Here, too, a possibility is shown, like a line end through simple pushing forward engaged with the plumbing fixture and can be secured. The ends of the brackets slide on corresponding ones Sloping surfaces of the tap from time to time until the hooks 17 lock. A release of this bracket 13 from the sanitary fitting 1 can be done by using a tool to clamp 15 are deformed inwards and then by pulling on one Line the bracket 13 is released from the sanitary fitting 1.

The device shown in Figure 5 corresponds to that in Figure 1. The sanitary fitting 1 is only slightly changed. The locking lugs 11 and Plate 7 is missing here. Instead, there are side guides of the sanitary fitting 1 two slides 20 transverse to the longitudinal axis of the line and Nipples 3 slidably guided. The two slides 20 are under Effect of a spring 21 which acts on the slide 20 inwards. In the secured state, they engage on the underside 9 of the flange 10 of the nipple 3. The underside 9 of the flange 10 is the side which faces away from the free end face 4 of the nipple 3. While at the embodiment of Figure 1 securing by attacking the Plate 7 on the underside 9 of the flange 10 is done here by engaging the slider 20 on the underside of the flange 10. The slide 20 have a front, that is, the nipple 3 facing End face 22, which extends so obliquely that when inserted of the nipple the flange 10 pushes the slide 20 to the side.

A tool 23, only indicated, serves to open the fuse, which is formed by a slotted sleeve. The slotted sleeve 21 has an outer end in the area facing the sanitary fitting Chamfer 24, the angle of which approximately corresponds to the angle of the inclined surfaces 22 the slide 20 corresponds. The inside diameter of the slotted sleeve 23 corresponds approximately to the outer diameter of the nipple 3. Because of the slot of the slot sleeve 23, this can be pushed laterally onto the line become. It can then go up in the direction of arrow 25 be pushed towards the sanitary fitting 1. Then the chamfer takes hold 24 on the end faces 22 of the slide 20 and pushes it back. Then the nipple 3 can be pulled back down. The The outer diameter of the flange 10 is slightly smaller than the inner diameter the sleeve 23.

The embodiment shown in Figure 6 of the proposed by the invention Device for fastening a line or a nipple is only slightly different from the embodiment in FIG. The two sliders 30, which work in securing the nipple 3 work exactly like the slider 20 of the embodiment FIG. 5 have projections 31 pointing away from the sanitary fitting 1, on which a fitter can attack to move the slide 30 radially to move outside against the action of the spring 21. This is left in Figure 6 shown. In this way, the line end can be without a tool can be removed from the sanitary fitting 1. Figure 7 shows yet another embodiment of a device for attaching a pipe end to a sanitary fitting. Here is in the valve or the valve body has a slot 32, the extends transversely to the bore for receiving the end 33 of the nipple 3. The slot penetrates the hole slightly, which results from the following Drawings will still result. When inserted of the nipple 3 is aligned with the slot 32, a circumferential groove 34, which is below of the flange 10 is formed. Below also means in this Case again that the side facing away from the free end 4 of the nipple 3 of the flange 10 is affected. The groove 34 also has the same width on like the slot 32. To secure the nipple 3 in the receptacle in the position shown is a slide 35, as shown in Figure 8 is, or a slide 36, as shown in Figures 9 and 10. First to the slide 35 of FIG. 8. The slide 35 has one approximate T-shape, with a crossbar 37, the outer contour is approximately circular arc-shaped. The outer contour turned away contains the slider 35 at the ends of the web 37 two arc sections 38 and in the middle between these arcuate sections 38 a locking section divided by a longitudinal slot 39 40. The two outer sides of the locking portion 40 included by a distance two notches 41. The slot 39 settles from the free end 42 of the locking section 40 starting from the outer contour where it enlarges into a wide opening 43.

The slide 36 in FIG. 9 differs from the slide 35 in FIG FIG. 8 only in that there is no arcuate outer contour, but that the two wings with the arcs 38 have one have straight front edge or outer edge 44, and that the Longitudinal slot 39 is separated from the opening 43 by a web 45.

These two wings with the leading edges 44 also result from the Figure 10, which is a view of the slide 36 of Figure 9 from the left in Figure 9 shows. The ends of the middle section 46 are for enlargement the stability bent upwards, at right angles the level of the slider.

The operation of the slide of Figure 8 is shown in the schematic Representation of Figure 11 can be seen. Figure 11 shows a cross section by the arrangement of FIG. 7 approximately at the height of the slot 32, in a very simplified representation. The three nipples 3 are already shown in place. Two are perpendicular to the slot Pins 47 arranged in the plane of the drawing. The slide 35 engages with its locking section 40 between the two pins 47, which lie in the position shown in the two first notches 41. This is the release position. Now the slider 35 in FIG. 1 shifted downward, the arcuate sections 38 of the two wings in the circumferential groove 34 of the two upper nipples 3 and simultaneously the front ends 42 of the locking portion 40 in the corresponding groove 34 of the lower nipple 3. This position is shown schematically in FIG. A single slide 35 locked So in this case three nipples 3. In the locking position Pin 47 in the other two notches 41 of the locking section 40th

To the slide 35 from the release position of Figure 11 in the locking position 12, a fitter can move a screwdriver into an opening between an edge 49 of the Sanitary fitting and the outer contour of the slide 35 engage and turn the screwdriver, see Figure 12.

To release the securing means formed by the slide 35 the screwdriver can be inserted into the space between the edge 50 the sanitary fitting and the edge of the opening 43 are used, see Figure 13. Then, by turning the screwdriver Slider 35 are moved to the release position that of the figure 11 corresponds.

Figure 14 shows a further possibility, such as two nipples 3 in a sanitary fitting 1 can be secured. The nipples 3 are already in theirs Insert inserted. A securing element is used for securing 51, floating freely in a transverse opening 52 of the sanitary fitting or is arranged centrally. It is roughly crescent-shaped, that is, it has a curvature at both ends, the two Curvatures are formed in opposite directions. At the apex the outer curvature engages a compression spring 51 which in one Hole 54 is supported. If the groove 34 is aligned with the transverse opening 52, the ends of the securing element 51 are pressed into this groove 34. The centering is done by the arch shape of the two ends of the securing element 51. The securing element 51 needs in the Not being rotatable in the middle, but it can be. This locking position is shown in Figure 14. The securing element contains approximately in the middle 51 a slot 55 for inserting a screwdriver. The locking element can be turned by turning the screwdriver 51 from the locking position, see Figure 14, in the Release position can be rotated, see Figure 15. Since the locking element 51 is not fixed around an axis, it is also possible move it so that only one of the two nipples 3 is released.

What is shown in Figures 14 and 15 for a sanitary fitting with two nipples 3 can also be implemented for a sanitary fitting with three nipples see Figure 16. Here, three nipples 3 are even arranged distributed over the circumference. In the middle is a safety element 61 rotatably arranged in a recess 62. The Securing element has three wings 63, the outer contour of which on one There is a circle that intersects the outer contour of the nipple. Between The three wings 63 have concave notches 64 which are shown in FIG Release position run approximately coaxially to the nipples 3. figure 16 shows the release position. By twisting the securing element 61 with the help of a screwdriver, the wings 63 in the grooves 34 of the nipple 3 are inserted, which is then the Represents locking position.
