Description

DESCRIPTION

Multipurpose fastener with a pipe connection angle

The invention relates to a multipurpose fastener with a pipe connection angle.

Pipe connection angles, also called battery connection angles, are used, for example, in drinking water supply to connect drinking water pipes. Such a connection angle may be attached to a wall to deflect a conduit running essentially parallel to the wall in a direction, for example 90 °. For this purpose, the pipe connection angle is connected to one or more pipe connection fittings as well as to a fixing element for fixing the connection angle directly to the wall or to a mounting rail. While direct wall mounting is sufficient for one connection angle, the mounting rail is mainly used to join multiple battery connection angles.

In a known system of the applicant, the battery connection angles are coupled to a rail with a specially designed guide system for this and fixed there. For direct wall mounting of a battery connection angle, there are additional wall discs to which the connection angle is attached. Figure 13 shows a general schematic representation of the known solutions.

Depending on the desired installation, various configurations are currently required to connect and set a battery connection angle. In particular, the installer must support various components in order to meet the needs. Therefore, the object of the invention is to provide a more flexible accessory for battery connections, in particular battery connection angles.

This object is achieved for the purpose of the present independent claim.

Accordingly, in the case of a multipurpose fastener with a pipe angle, a flat connecting body is provided having at least two fastening openings or through holes for fastening the element to a wall. The pipe angle, in particular the battery connection angle, the wall angle or other fluid carrying means, is attached to the front side of the connection body with two connections. The holes in the flat connecting body are conveniently designed to be freely accessible.

At the rear of the connection body is arranged at least one fixing device. The fixing device is designed in such a way that it has a corresponding fixing element as a counterpart in a mounting part, so that the connecting body can be secured against rotation and fixed in at least two positions, so that when least one of the fixing through holes in the connection body has an opening in the mounting piece to hold the connection body in the opposite mounting piece

In one embodiment, the fixing device in the connection body comprises at least one recess. In this embodiment, a locking pin is additionally provided as a counterpart, which may be engaged in the recess. This counterpart can be attached to the mounting piece, but can also be present as an additional element. The counterpart allows a torsion-proof coupling of the connecting body to the mounting piece.

In this way, the multipurpose fastener according to the invention can be fastened directly to a wall or a cleaning element by means of several screws through the at least two fastening through holes provided in the connection body. In the case of existing mounting parts, for example mounting rails or mounting elements, these comprise part of the fixing device in such a way that the connecting body can be coupled with its rear part to the mounting piece. As a result, two different suitable embodiments are no longer necessary, either for mounting on a mounting rail or directly on the wall. Rather, the multipurpose bra according to the invention can be used for both types of fastening.

In one embodiment of the invention, the fixing device at the rear of the connecting body comprises an asymmetrically designed recess. The counterpart, for example a fixing or positioning bolt, is also designed asymmetrically in this embodiment, such that at least two different bolt positions are provided within the recess at the rear of the connecting body. In this way, the connecting body can be clamped to the mounting piece in different positions. The positions are designed in such a way that when the connecting body is flanged on the positioning bolt to the mounting piece, at least one of the two clamping through holes is opposite a suitably arranged opening in the mounting piece, thus so that the body of the connector is firmly but reversibly fixed by an additional connection to the mounting piece. For this purpose, the opening in the mounting piece may have an internal thread. The connection can be a screw connection, but also a tight bolt or plug connection.

The asymmetric design of the clamping device results in a non-rotating connection of the connecting body to the mounting piece. In general, this allows a quick and easy attachment of the connector body to the mounting piece, even without an installer having to know the exact position of the fixing device and its elements.

In another embodiment of the invention, the fixing device is designed with two mutually adjacent recesses in the connecting body. The bolts can be inserted into the recesses, which are present as a removable and movable element or, in an alternative embodiment, are attached to the mounting piece.

In one design of the invention, several recesses are provided as fixing elements in the connecting body and two fixing bolts. Due to the different position of the fixing bolts on the connector body, a different position of the connector body relative to the mounting part can be achieved.

In a particularly preferred embodiment, a first fixing element in the form of a recess with a first diameter and a second fixing element in the form of a recess with a second diameter are provided. The different diameters allow a more precise positioning or a clear assignment of possible fixing bolts on the mounting part. The recesses can also be of different depths. In this way, an installer can quickly find the correct position of the connecting body relative to the mounting piece during mounting and bring the body into the desired position by rotation.

Alternatively, the fixing device comprises two securing or fixing bolts of different lengths. This allows an installer to attach the connecting piece to the mounting piece by means of the longer fixing bolt and then to secure it against rotation in the desired position by coupling with the second bolt. Advantageously, several recesses in the body of the connector may be provided for the second fixing bolt or several recesses in the mounting piece for the second fixing bolt. This allows, by means of the first fixing bolt, a coupling between the connecting body and the mounting piece and a positioning of the fastener and thus the pipe angle in different positions through the second fixing bolt.

In one design, the fixing bolts or the fixing elements can be made of a material that is softer than the material of the mounting part or the material of the connecting body. The complete fixing and clamping of the connector body in the mounting piece by a connection through one of the openings in the connector body is reversible. Due to the different position of the connector body in the mounting piece, various openings are required in the connector body or mounting piece, at least one of which is opposite the other when the connector body is placed against the rotation of the mounting part.

The fixing bolts or the securing elements can be equipped with retaining pins or clips or retaining elements, so that after the connecting body has been placed against rotation in the mounting part, a first, is achieved, although rudimentary, fastening and mounting. In this way, the assembly is simplified since an inadvertent "fall" of the connecting piece is avoided. Of course, locking or securing pins can also be used.

Other accessories and designs result from the dependent claims. Components with the same effect or function have the same reference symbols.

The individual features shown herein in the example embodiments are not limited to the specific embodiment. It goes without saying that the individual sub-elements of the fixing elements can be connected and arranged both on the connecting body and on the mounting parts. Different shapes and arrangements are also possible.

Figure 1 shows a flexible bra according to the proposed principle. The flexible fastener is suitable both for direct wall mounting and as an additional mounting piece. For this purpose, the fastener comprises a flat connecting body 4, the rear of which faces the observer. A battery connection angle comprising the two connections 2 and 3 is attached to the flat connection body on the opposite front side. A pipe is flanged at connection 2, which runs, for example, in parallel along the wall. The connection 3 in turn serves to hold a tube, a pipe or some other element which in this case may be substantially perpendicular to the wall and which can transport a fluid medium.

The flat connecting body 4 has three spaced openings 40, 41 and 44, the connecting line of which essentially forms an isosceles triangle. The openings are designed for fastening through clamping through holes 40, 41 and 44 and are easily accessible from the front of the connection body 4. When the fastener is connected to the wall, the screws can be inserted through through fixing holes and screw into wall plugs. Through the openings a three-point fixation of the connection body and thus the holder with the battery connection angle is possible.

On the other hand, a further fixing device is provided for fixing to a mounting rail. In the example shown, this comprises two recesses 42 and 43, which are arranged essentially perpendicularly below the opening 41. In this embodiment, one of the recesses is also located in the connection line between the two fixing holes 40 and 44.

The diameter of the two recesses 42 and 43 is smaller than that of the clamping through holes 40, 41 and 44. Furthermore, the recesses are relatively flat and, in particular, represent only depressions, but not through the holes in the flat connecting body 4. These can be round, angular or otherwise have other cross sections. Similarly, the recesses can have different shapes, so that mounting can only take place in predetermined positions.

Figure 2 shows the additional processing of the flexible bra. While the recesses 42 and 43 remain essentially free for attachment to the wall, the locking pins 46 and 47 are now inserted into the recesses for attachment to a mounting body. Securing pins may be available separately. In the present case, they are inserted into the recesses of the connection body, but they can also be attached to a mounting rail, so that the connection body can simply be plugged in.

Figure 3 now shows a mounting rail to which the flexible fastener can be clamped and attached. For this purpose, the mounting rail, which is suitable for holding two battery connection elements or angles in the illustrated embodiment, comprises a plurality of holes 53, 54, 55, 56 and 57 in the two different positions 51. These are left on the yoke between the two legs and arranged to the right of the center of the mounting rail yoke. Its distance from the shortened legs or to the other respective region is selected so that After the individual fixing elements are flanged, on the one hand, they do not interfere with each other, but on the other hand they do not protrude beyond the U-shaped area. another shaped rail.

Figure 4 shows an enlarged representation of the position 51 to clarify the function of the individual holes 53 to 57. The openings 53 and 54 correspond to the clamping holes 41, 40 and 44 of the flat connecting body 4.

In contrast, the fixing holes 55, 56 and 57 have a smaller diameter, which corresponds essentially to the diameter of the securing pins 46 and 47 in Figure 2. The distances between the holes 55 and 56 from each other or the holes 55 and 57 to each other are also selected so that they correspond essentially to the distance between the securing pins 46 and 47. As shown, the large hole 53 is also located on a line that passes through the small fixing holes 55 and 57 , the hole 54 is located on a line defined by the small fixing holes 55 and 56.

Due to the arrangement of the large holes as well as the small holes relative to each other, different clamping positions of the flat connecting body with its fixing pins on the mounting piece are possible. The position of the large holes 53 and 54 corresponds to the position of the clamping hole 41 in the different positions. In this way, the flat connecting body can be clamped to the mounting piece in a first step by means of the two securing pins, in which the securing pins are inserted into the small holes corresponding to the desired position. Then, in a further step, a screw or other fixing element, for example a pin or bolt, can be inserted and fixed through the clamping hole 41 and the opposite hole 53 or 54. For this purpose, the holes large 53 and 54 may have a suitably designed internal thread.

Figure 5 shows a representation of the flexible fastener in a flanged state in a mounting part. The position of the connection body, and therefore also the position of the battery connection angle 2 and 3, is selected so that it extends essentially at 45 ° with respect to an axis traversed by the longitudinal leg of the mounting piece. In particular, the two locking pins 46 and 47 are inserted into the fixing holes 55 and 57, so that the opening 53 is located directly above the fixing hole 41. However, the opening 56 and the opening 54 are free and are coated on the back by the surface of the connector body 4.

In Figure 6 another mounting position of the battery connection angle with the flat connection body 4 is shown. In this case, the securing pins 46 and 47 are clamped in the fixing holes 55 and 57 in the correct position of the mounting piece. In this case too, the holes 56 and 54 in the mounting piece are lined by the connection body 4, while a fixing element is inserted into the hole 53, for example, a screw with its internal thread is screwed, to fix and finally clamp the connection body and the battery connection angle.

Due to the position of the fixing holes 55, 56 and 57 in the mounting piece 50 and the mounting holes 53 and 54, the connection body 4 can be connected in the two positions shown in Figures 5 and 6 and also be rotated 90 °. In this case, fasteners, for example screws or pins, are inserted into clamping holes 40 and 44 for final assembly and, if applicable, are connected to the internal thread in clamping holes 53 and 54.

In the embodiment shown so far, the different positioning of the connecting piece is achieved by means of the fixing device with locking pins and corresponding recesses in the connecting piece as well as in the mono piece. The positions of the securing pins 46 and 47 with respect to the connecting piece 4 are already predetermined by the recesses. The different positioning results from the fixing and clamping holes additionally arranged in the mounting rail 50.

However, in an alternative embodiment, it is also possible to effect a different positioning of the connection body and, therefore, of the battery connection angle by means of an embodiment and a corresponding positioning of the recesses in the connection body itself. Figure 12 shows a related embodiment.

In this case, the connecting body is designed as a T-shaped or a cross-shaped element in contrast to the conchoid shape of Figures 1 and 2 in order to save additional material.

A first recess 42b of a fixing element 42a is provided along the connection line of the clamping holes 40 and 44. This has a diameter that is greater than that of the clamping holes 40, 41 and 44 and serves to receive a corresponding locking or securing pin. The recesses 42c, 42d and 42e with a significantly smaller diameter are disposed above the recess 42b in a rotationally symmetrical manner at 45 °. Recesses 42c through 42e run along an imaginary circular line around the center of recess 42b. The fixing elements serve to fix the position of the connector body 4 on a mounting rail.

In this embodiment, the mounting rail also includes the locking pins for connecting the connector body. Specifically, a first securing pin of the fastener is designed in the mounting rail with a diameter essentially corresponding to the diameter of the recess 42b. This pin is also designed to be slightly longer than the positioning fixing pin so that the installer can easily position it during assembly. The securing pin on the mounting rail, which is hooked in one of the recesses 42c, 42d and 42e of the fixing element, is arranged in a direction at the corresponding distance. In addition, three additional mounting holes are provided in the mounting rail, which are at the same angle relative to the center of the main locking pin with a large diameter of 45 ° to each other. These correspond essentially to the alignment of recesses 42c, 42d and 42e in the connecting body.

In this way, it is possible to achieve a different positioning of the connecting piece with respect to the mounting piece by designing the various recesses in the fixing device on the rear side of the connecting body. If the securing pin for the recesses 42b protrudes slightly more than the locating bolt for one of the recesses 42c, 42d and 42e, a particularly simple assembly is possible. Therefore, an installer can position the connector body in a particularly simple way through the large diameter locking pin and then adjust the final position of the connector body by rotating it around the center of the recess 42b.

A further embodiment of the flexible fastening element according to the invention is shown in Figure 7. In this the fastening element is realized by an asymmetric recess, for example in the form of an inverted mushroom, shuttle or anchor. The recess 48 is shaped to receive a corresponding counterpart 60 available separately or integrated into the mounting piece. Counterpart 60 forms the securing pin of the fastener for connection to a mounting piece. A suitable corresponding mounting piece is shown from the front in Figure 8. In this case, too, two different positions of the connection piece and therefore of the battery connection angle are realized. The mounting piece 50 contains in its U-shaped leg two groups of holes with the elements 46a, 53 and 54. The distance between the legs and the respective regions 51 along the yoke is selected so that when the angle of battery connection and connection body are flanged, do not interfere with each other. Depending on the length of the yoke, additional regions may also be provided.

Figure 9 shows an enlarged representation of a region 51. Holes 53 and 54 are equipped and form the clamping holes for a later final fixation of the connecting body by means of a bolt, screw or other clamping element. As shown, recess 46a is formed by two individual recesses 46b and 46c, each representing the negative shape of the counterpart and securing pin 60. Elements 46b and 46c are offset from each other by 45 °, in which the "mushroom stem" lies in each case in a connection line with one of the clamping holes 43 and 54.

The recess 46a as well as the clamping holes 53 and 54 thus form the connection variants for a connection body according to Figure 7 with a counterpart and a securing pin 60 inserted therein. Figure 10 shows a corresponding front view of a representation with flanged fasteners. In a first form, in which the battery connection angle connection 2 runs essentially perpendicular to the longitudinal axis of the yoke, the hole 41 of the connection body 4 is located directly over the clamping hole 53. A bolt or pin It is inserted into the hole 41 and firmly connected to the mounting piece for final fixing and positioning of the connection piece and the angle of the battery connector. The two holes 43 and 40 are lined by the material of the mounting piece. On the other hand, the right connection flange is inclined at 45 °, so that the clamping hole 41 is located above the clamping hole 43.

Figure 11 finally shows the rear of the embodiment of Figure 10, in which the counterpart or securing pin 60 is mounted in the two different positions in the recess 46a so that it cannot be rotated. This protection against rotation is achieved by the additional asymmetric recess 46b or 46c, the mushroom stem.

In this way, a single flat connection body with an attached battery connection angle can be used both as a direct wall fitting and for mounting on an additional mounting piece. A different positioning is achieved by selecting locking pins, recesses or other suitable elements for fixing. The invention has the advantage of further saving material by suitable implementation of the fixing element and, at the same time, simply by placing a battery connection angle with its connection piece in different orientations. It is particularly advantageous if the fastener is itself asymmetrical, for example it has recesses of different sizes. The locking pins in the example embodiments may be available as individual parts, but may also already be firmly connected to a mounting piece. So that the shear forces that occur during the subsequent final fixation do not damage the individual fixing holes and recesses, it may be desirable to implement possible counterparts and used securing pins of a softer material than the mounting part or the connecting part. fixing element. In addition to the battery connection angles that are shown herein, any other shape of pipe angles, pipe runs, connections, distributors or other elements are also conceivable if they are attached to the connection body.
