Abstract

The invention relates to a system holder (10) for receiving an elongated object, such as a hose, in particular a protective hose, having an upper part (18) and a lower part (12) which form, in a closed position, a circumferential edge (20), that encloses an outlet opening (22) for an object to be received, and which upper and lower part are pivotably connected to each other by means of a hinge (16) and releasably fixed to each other in the closed position. According to the invention, an insert (34) is provided, which is releasably fastened to the upper part (18) or the lower part (12) and which comprises a part (46) of a tongue and groove joint, said part being arranged on the circumferential edge (20) and extending to some extent in the circumferential direction of said edge.

Description

The invention relates to a system holder according to the preamble of claim 1.

Such system holders are known, for example, from DE 203 80 318 U1 and serve for fastening an elongate object, such as a corrugated hose or a pipe, to a wall or to a machine component. An upper part and a lower part form a peripheral opening surrounding a passage opening. The upper part and the lower part are hinged together by means of a hinge, so that they can be pivoted apart to release the passage opening in order to insert the object to be received in the radial direction into the passage opening. In order to fix the upper part and the lower part immovably to each other, a connection, in particular a locking connection is provided at a distance from the hinge, which can be released for the purpose of opening. If a protective tube such as a corrugated tube is inserted into the system holder, it is regularly provided with a retaining ring which encloses it and whose outside dimensions are matched to the dimensions of the passage opening. The retaining ring has two half shells which are detachably interconnected and whose outer contour corresponds in sections to a spherical surface. Due to this geometry, the retaining ring and thus also the hose received in it in the system holder is limitedly pivotable. While this may be desirable for some applications, there may be applications where a rigid connection between the system holder and the hose is preferred.

It is therefore an object of the invention to develop a system holder of the type mentioned in such a way that it is more flexible. The object is achieved by a system holder with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

The invention is based on the idea that a tongue and groove joint, which extends at least to some extent in the circumferential direction of the peripheral edge of the passage opening, prevents twisting of the object received in the system holder with respect to the system holder. By means of the tongue and groove connection thus a rigid connection between the system holder and the object received in it, for example, provided with a retaining ring corrugated tube created. By the insert is releasably secured to the system holder, the latter can be converted in a simple manner by removing the insert so that the system holder and the object received in it again can be pivoted against each other limited.

It is preferred that the insert has the spring of the tongue and groove joint to be formed with the male object, the spring projecting into the passage opening. However, it is equally possible that the insert has the groove of the tongue and groove connection.

The insert expediently has two fastening hooks, which are arranged at free ends of tongues extending essentially radially with respect to the passage opening and project in opposite directions. The attachment hooks each engage behind a fastening surface on the upper or lower part. By this measure, a simple attachment of the insert in the upper or lower part is given, the attachment by simply bending the elastic tongues by hand or by means of a screwdriver or a similar tool can be solved again. It is preferred that the attachment surfaces are part of the outer surface of the upper or lower part, so that from the outside to the fastening hooks or the tongues can be attacked without the system holder must be opened. Advantageously, the insert also has a different color at least on its attachment hook than the upper or lower part receiving it, so that the attachment hooks are clearly visible. In addition, an attractive design can be achieved by the different colors.

Another aspect of the invention relates to the fixation of the upper part on the lower part. Although known from the prior art latching connection has proven in practice to be easy to handle and sufficiently stable. However, it is possible that when exposed to large forces or by operator error or accidental attack on the locking connection between the upper and lower part of this fixation can be solved. The system holder with the features of the independent claim 8, however, provides an additional backup of the latching connection. The latching connection is formed by a latching hook on one part and a transverse web on the other part, wherein a first transverse surface of the transverse web is engaged behind by the latching hook in the closed position. The inventively provided securing clip is linearly displaceable between a securing position in which it engages around the latching hook and the transverse web, and a release position in which it is withdrawn from the latching connection, wherein it is guided at least in sections on a guide rail. If the securing clip is released from its securing position, the guide on the guide rail causes it not to be put away or held fast by the fitter, but simply slips down a bit on the guide rail and is held there.

Suitably, the securing clip has a substantially U-shape with a first leg, which has a guide slot for receiving the guide rail, and with a second leg, which at its free end a latching projection for engaging behind the crossbar on a Having the first transverse surface facing away from the second transverse surface in the securing position. It is envisaged that the two legs are spread apart against an elastic restoring force. Suitably, the guide slot is closed towards the free end of the first leg and towards the second leg, whereby the displaceability of the securing clip on the guide rail is limited. The guide rail is advantageous in cross section T-shaped with a arranged at a free edge transverse rib, wherein the guide slot is narrower than the transverse rib. This prevents the safety clip from falling off the guide rail by engaging behind the guide slot by the transverse rib. In this case, it is preferred that the guide slot is widened at its end remote from the free end of the first leg to a width which is greater than the width of the transverse rib, so that it can be removed by carrying out the transverse rib by this widening of the system holder.

Suitably, the latching hook is arranged on the upper part and the transverse web and the guide rail are arranged on the lower part. This implies that the free ends of the legs of the securing clip point towards the top. If the system holder is fastened with the upper part upwards, for example, on a bottom wall, then the safety clip slips downwards after being released from its securing position due to gravity without any further action.

As well as the use of the fuse clip may have a different color than the upper part and the lower part, preferably the same color as the insert. The security clip is then clearly visible and can also form a design feature.

In the following the invention will be explained in more detail with reference to an embodiment schematically illustrated in the drawing. Show it 1 shows a system holder in the closed position in a perspective view.

3 shows the system holder according to Figures 1 and 2 in the open position. 4 shows an insert of the system holder according to FIGS. 1 to 3 and FIG. 5 shows a securing clip of the system holder according to FIGS. 1 to 3.

The system holder 10 shown in the drawing serves to receive and attach elongate objects, for example corrugated hoses. It has a lower part 12, which is provided with fastening openings 14 for receiving screws, and a hinged to the lower part 12 by means of a hinge 16 upper part 18. In the closed position shown in FIGS. 1, 2, in which the upper part 18 and the lower part 12 are releasably connected to one another at the side opposite the hinge 16, they form a peripheral edge 20, which has a passage opening 22 for the male Enclosing the object. The detachable fixing of the upper part 18 on the lower part 12 is formed by a latching hook 26 arranged on a projection 24 on the upper part 18 and a transverse web 28 on the lower part 12, wherein the latching hook 26 engages behind a first transverse surface 30 on the transverse web 28. In the illustrated embodiment, the passage opening 22 extends approximately halfway to the upper part 18 and the lower part 12. In the region of the hinge 16 between the upper part 18 and the lower part 12 is a outwardly, away from the passage opening 22 widening gap arranged, the limits the pivotability of the upper part 18 relative to the lower part 12, as shown in Fig. 3. In the upper part 18, an insert 34 is received, which extends in the circumferential direction of the passage opening 22 and forms part of the peripheral edge 20. The insert 34 (FIG. 4) has a curved base body 36 and two tongues 38 projecting from the base body 36 substantially radially with respect to the passage opening 22, which each have a fastening hook 40 at their free end and are elastically deformable. The fastening hooks 40 protrude from the tongues 38 in opposite directions, in the embodiment shown they face each other. The fastening hooks 40 each engage behind a fastening surface 42 on the upper part 18, wherein the fastening surfaces 42 are accessible from the outside and thus form part of the outer surface 44 of the upper part 18.

The insert 34 also has a circular arc, a piece in the passage opening 22 projecting rib 46 which is intended to form the tongue a tongue and groove connection. The associated groove, into which the spring 46 engages, is located on the male object. By way of example, a holding ring arranged around a corrugated tube in the manner of a protector and composed of two half-shells, whose outer dimensions are adapted to the inner dimensions of the passage opening 22, is provided with the associated groove.

The production of such a tongue and groove connection then prevents the retaining ring in the passage opening 22 can pivot limited. A rotation about the central axis of the passage opening 22 is inhibited by the tongue and groove connection. But if a mobility of the received in the passage opening 22 object desired, the insert 34 can be easily removed from the upper part 18 by the tabs 38 are bent away from each other elastically until the mounting hooks 40 come out of engagement with the mounting surfaces 42. In the embodiment shown, the insert 34 is arranged in the upper part 18. But it could just as well be arranged in the lower part 12. However, the arrangement in the upper part 18 has the advantage that the fastening openings 14 are not covered by the insert 34. The arrangement of each insert 34 in the upper part 18 and lower part 12 is possible.

In order to secure the latching connection formed by the latching hook 26 and the transverse web 28 against external influences, a securing clip 50 is provided, which is guided on a guide rail 52 on the lower part 12 so as to be longitudinally displaceable. The guide rail 52 is T-shaped with a arranged on a projecting base 54 transverse rib 56. The securing clip 50 has a first leg 58 and a second leg 60, which are elastically flexible connected to each other. In the first leg 58 a to the free end 62 and the second leg 60 toward closed guide slot 64 is arranged, which has a smaller width over the majority of its length than the transverse rib 56, but the second leg 60 is expanded to a width, the is greater than the width of the transverse rib 56. At the free end 66 of the second leg 60, a latching projection 68 projecting in the direction of the first leg 58 is arranged.

As shown in Fig. 1, the securing clip 50 is intended to secure the latching connection 26, 28. For this purpose, it engages in a securing position (FIG. 1) both the latching hook 26 and the transverse web 28, wherein the latching hook 26 is arranged in the region of the connection between the first leg 58 and the second leg 60. The latching projection 68 engages behind a second transverse surface 70 remote from the first transverse surface 30 on the transverse web 28, so that the securing clip 50 can only be removed from this securing position if the two legs 58, 60 are spread open against the elastic restoring force. If this is the case, the securing clip 50 falls down and the transverse rib 56 penetrates through the widening of the guide slot 64 and engages behind it the securing clip 50 is guided in a linearly displaceable manner on the guide rail 52 in the last section of the path traveled by it from the securing position into a release position in which it is withdrawn from the latching connection 26, 28 (see FIG. In Fig. 3, the securing clip 50 is shown in its release position in which the guide rail 52 abuts the end of the guide slot 64.

Again, it goes without saying that in the manner of a kinematic reversal of the locking hooks 26 may also be arranged on the lower part 12, so that the transverse web 28 and the guide rail 52 are then arranged on the upper part 18.

The lower part 12, the upper part 18, the insert 34 and the securing clip 50 are in the embodiment shown in each case integrally formed as injection molded plastic parts. For visual highlighting and to create an appealing design, the base 12 and top 18 are held in a first color and the insert 34 and the security clip 50 are held in a second color. The first color is black here, the second color is red.

In summary, the following should be noted: The invention relates to a system holder 10 for receiving an elongated object such as a hose, in particular a protective tube, with an upper part 18 and a lower part 12, which in a closed position form a circumferential edge 20, which has a passage opening 22 encloses for the male object, and which are pivotally connected to each other by means of a hinge 16 and fixed to each other in the closed position releasably. According to the invention, an insert 34 which is detachably attached to the upper part 18 or the lower part 12 is provided, which has a part 46 of a tongue and groove connection which is arranged on the circumferential edge 20 and extends for some distance in its circumferential direction.
