Description

The The invention relates to a clamp for fixing strand-like Components, in particular for hoses and / or Cables and / or pipelines, with clamp bodies which can be fixed to each other, the receiving channels between them for the components to be fixed form, and with a latching device for mutual locking the clamp body in a fixed state, wherein the latching device on a clamp body at least having a locking body with a latch, which when together approximate clamp bodies in one by elasticity the locking body caused latching movement with an am other clamp body located locking surface locked.

at Installations involving hoses or cables or pipelines are laid on plant parts, it may be due to static or dynamic loads (vibration loads) to damage come the respective strand-like components. To the To counteract, it is state of the art, in critical places bells to install, which act both as a spacer and for securing the position serve the components. When the components in question in the receiving channels should be installed before the clamp body final are attached to the relevant system part by means of a holder, the assembly processes are cumbersome, time-consuming and sometimes difficult, because at the Montagevor gear no the clamp body is fixed in position, so that during the installation process Both clamp body must be handled and positioned.

By the GB Pat. 1,224,535 For a clamp of the generic type has already been proposed to provide a locking device on the clamp bodies, by means of which the clamp body can be fixed together in an approximate state to each other. This simplifies assembly operations, in particular, if such a clamp is to be installed only as a spacer flying, so that no attachment to a holder is provided. Adversely, however, this known solution does not meet the requirements to be placed on the reliability. Both locking body and locking surfaces, which are formed by outer wall portions of the clamp body are exposed in the known solution unprotected external loads, so that it can come by external force to release the latching.

in the In view of this, the invention has the object, a clamp to provide the kind considered that is due to a reliable locking, even under rough operating conditions, distinguished.

According to the invention this task is solved by a clamp that features of claim 1 in its entirety.

After that an essential feature of the invention is that for the engagement of the locking lug on a clamp body located respective detent body in the other clamp body Recording space is formed. This is the latch in question in a chamber against external forces, which could cause a release of the catch, protected. To be "chambered" outwardly Construction of Ra steinrichtung, however, an intentional unlocking to allow the latching is further according to the invention provided that the receiving space from the outside accessible Has engagement opening over which an unlocking tool from the outside is introduced to the latch to move against the direction of the latching movement.

at advantageous embodiments are two in to the longitudinal axis the clamp body of symmetrical arrangement nearby the side walls of a clamp body located Catch body provided, the locking lugs approximated when approached Clamp bodies in one each within the concerned Side wall of the other clamp body located receiving space intervention.

in this connection can the engagement opening in the respective receiving space laterally delimiting wall portion of the respective side wall provided and designed the kind and on the in the receiving space located Latch be aligned that this through a transverse to the longitudinal axis displacing insertion movement of the unlocking tool the direction of the latching movement is displaced. Designed by it an optionally carried out unlocking especially easy and convenient, because the appropriate tool of the most accessible side of the clamp body is insertable.

Preferably are the two locking body in the longitudinal axis perpendicular Direction aligned with each other, the arrangement with particular advantage can be taken so that the locking body centrally between two adjacent recording channels are arranged. In such construction, a for the passage of a retaining screw provided through hole in the area between the two recording rooms by the extend relevant clamp body.

With regard to the design of the locking body, the arrangement may be made such that their locking lugs project in a direction perpendicular to the longitudinal axis direction against the adjacent side wall. If in this case the respective engagement opening through an opening provided in the respective side wall slot opening is formed, an opening edge of the slot opening, which extends in the longitudinal direction, form the locking surface on which the locking hook hooked when the detent body biases the locking lug against the outside by its elastic force, so that the Locking lug slides when approaching the clamp body on the inner wall of the receiving space until reaching the slot opening and then locked at the opening edge. For releasing the latch can be pressed inwardly for the release of the locking surface by means of the introduced through the slot opening Entriegelungswerkzeuges.

at alternative embodiments in which the locking lugs projecting in the direction of the longitudinal axis, the engagement opening by a vertical to the longitudinal axis bore in the respective side wall be formed, which is perpendicular to the longitudinal axis bore axis is aligned with the locking lug located in the respective receiving space, that these can be introduced through a longitudinal axis of the bore Unlocking tool against the direction of the latching movement is displaceable.

Both Clamp body can be made of a plastic material in one piece and via a joint with each other be formed contiguous, wherein the joint serves as a film hinge, which forms a folding axis around which the Clamp body can be pivoted to juxtaposition. In such embodiments, which are characterized by a special ease of installation is guaranteed, that when folding the clamp body, the locking lugs And locking surfaces are aligned with each other, so that when Folding or closing process without taking special care should be spent, the secure locking he follows.

11 one opposite 10 enlarged and broken drawn partial cross-section corresponding to the section line XI-XI of 9 , and

12 one of the 6 corresponding representation of the second embodiment.

The 1 to 6 show a first embodiment of the clamp according to the invention, wherein the embodiment is designed in the manner of a so-called two-tube clamp, wherein a first clamp body 1 and a second clamp body 3 are provided, which are in an approximate state, as in 1 to 5 is shown between receiving channels 5 form for a positional fixation not shown strand-shaped components. The approximated and, as described in more detail below, locked together clamp body 1 . 3 are by means of a cover plate 7 , a clamping and fastening screw 9 and a foot plate 11 , which is provided with a female thread, clamped and anchored to a part of the plant, to which the foot plate 11 attached, for example, is welded.

Further details of the embodiment of the clamp body 1 . 3 and latching are the clearest 3 to 6 removable. As 6 shows are the clamp body 1 and 3 integrally molded in one piece from a plastic material and connected together at a junction, which is a bending hinge 13 forms, one to the longitudinal axis 16 vertical folding axis defined. The 1 to 5 show the clamp body 1 . 3 each in one by pivoting about the axis of the bending hinge 13 folded position. How most obvious 2 and 4 it can be seen have the clamp body 1 . 3 in their central area stepped through holes 15 on, when the folded state of the clamp body 1 . 3 aligned with each other and for the passage of the screw 9 are provided.

At the first clamp body 1 are on both sides next to the hole 15 latching body 17 molded, the end-locking lugs 19 form, which towards the outside, ie to the side wall 21 the clamp body 1 . 3 to project out and form hooking surfaces. The locking lugs 19 have inclined abutment surfaces adjacent to the interlocking surfaces 23 on. When folding together the clamp body 1 and 3 run the contact surfaces 23 the by their own elasticity slightly biased outward detent body 17 on the other clamp body 3 and are thereby bent inward. This happens while the ratchet body 17 in one in the other clamp body 3 trained recording room 27 enter. This is outwards, ie to the outside of the side wall 21 out, over a slot opening 29 open. This not only forms an engagement opening, which allows access for an unlocking tool (not shown), but it also forms the locking surface with its longitudinally extending opening edge 25 at which the respective latch 19 hooking occurs after the run-up surface 23 has overflowed the opening edge.

The in the clamp body 3 trained recording room 27 is, as also out 4 and 5 is clearly removable, at the the clamp body 1 facing side open, so that when folding against each other, the clamp body 1 . 3 the locking lugs 19 in the recording room 27 can enter. If the clamp body 1 . 3 are close to each other, is the recording room 27 but here by the adjacent surface of the clamp body 1 closed, leaving the recording room 27 only via the slot opening serving as the engagement opening 29 is accessible from the outside. For releasing the locking can be any unlocking tool with transverse to the longitudinal axis 16 extending direction are introduced to the latch 19 against the elasticity inward for the release of the locking surface 25 to move.

This in 7 to 12 shown second embodiment differs from the first embodiment substantially only by a different design of the locking device. Here are locking body 17 in the same way as in the first embodiment on both sides of the central holes 15 the clamp body 1 . 3 arranged, wherein the latching noses 19 but not in the transverse direction and projecting outwards, but in each case parallel to the longitudinal axis 16 , Accordingly, for the interaction with the locking lugs 19 provided latching surface 25 not at the opening edge of one in the side wall 21 located slot opening 29 provided, as is the case in the first embodiment, but at a paragraph 31 that is inside the reception room 27 in the clamp body 3 is formed, see 9 and 10 , To be on the relevant side wall 21 an engagement opening for the access of a Entriegelungswerkzeuges to the receiving space 27 to form is located in the sidewall 21 of the clamp body 3 a transverse bore 33 whose bore axis is oriented so that an unlocking tool inserted along the bore axis, the inclined contact surface 23 at the reception room 27 located latch 19 contacted, so that in turn from the locking surface 25 at the heel 31 is liftable. As can be seen, see in particular 7 , is the recording room 27 laterally except for the transverse bore 33 closed. Against the clamp body is the receiving space 27 through the adjacent surface of the clamp body 1 closed while the opposite end of the recording room 27 through a cover plate 7 lockable on the in 8th shown top of the clamp body 3 lies. Thus, in both embodiments shown, the latching device is outwardly closed, apart from the engagement openings for an unlocking tool, and therefore protected against external forces. As unlocking tool (not shown) can serve in particular the tip of a screwdriver, the tapered end tip of a Entriegelungsstabes, for example in the form of a hexagon socket or the like more, provided that it can penetrate with a corresponding operating game in the engagement opening of the respective receiving space.
