Description

Band element to surround and hold objects.

  The invention relates to a strip element for surrounding and holding objects, comprising a support region for the objects to be held, consisting of a curved support part and a strip-shaped enveloping part with at least one element. which can be removably connected to at least one engagement element and with a fastening region connected to the

  support region for fixing the strip element to a support.

  Strip elements of the aforementioned type are used mainly to hold and assemble elastic tubes, electric cables and the like to obtain an overall bandage holding parts, for example in the field of show electronics or

in the automotive industry.

  As regards the state of the art, a cable fastening strip is already known which comprises, between a fastening region on the one hand, a strip-shaped wrapping part provided with several branches and on the other hand, at the end of a curved collar, an engagement element having engagement regions (DE-PS 28 13 484). This cable tape can only be used in special fields and it follows that it is not possible, for example, to perfectly maintain a variable number of cables of

  smaller or larger diameters.

  Other cable ties are also designed only for special areas of use and are therefore not suitable for universal use (US-PS 3,930,287,

US-PS 3,471,190, US-PS 3,486,200).

  The present invention therefore aims to constitute a strip element of the type mentioned in the preamble so that it can be used for a large number of targets or tubular elements of various diameters while maintaining them firmly. The aim is therefore

  to create what is called a universal band fastener.

  According to the invention, this object is achieved due to the fact that the curved support part is constituted by an elastic internal shell and -2- by a rigid external shell surrounding the latter. The advantage is thus obtained of being able to perfectly maintain cables of various diameters and according to a greater or lesser number in the strip element which can be used universally. This strip element can be closed firmly and then reopened, while otherwise the cables have no possibility of slipping and that is avoided

  perfectly creaking and clicking noises.

  The strip element according to the invention can be connected universally to a support, the region for fixing the strip element according to the invention being designed for a T-shaped lug, a sawtooth lug as well only for shaped or round holes formed in the support. One can also imagine other possibilities of use. The field of use of the strip element according to the invention comprising the attachment region can be used for example advantageously throughout the interior of a bodywork of a motor vehicle, from the enclosure reserved for the engine, dashboard and underbody as well as in the passenger compartment and the trunk, while a wide variety of temperatures cannot have a negative influence on a reliable fixing of the

  cables if appropriate materials are used.

  According to one embodiment of the invention, the elastic internal shell is connected directly to the wrapping part by a thin intermediate region, the latching element provided on a curved collar facing the bearing region. The elastic internal shell can advantageously be produced by a flexible strip comprising hollow bodies arranged at a certain distance from each other and directed towards the internal side of the rigid external shell, these hollow bodies having for example a trapezoidal shape. The assembly being carried out, that is to say when the cables are surrounded, the hollow bodies of trapezoidal shape are pressed by applying a constraint towards the outside and they are applied against the internal side of the

  rigid outer shell. This prevents unwanted opening.

  According to another embodiment of the invention, there is also the possibility of making the fixing region - 3 - of the strip element continue on the one hand by the support region constituted by the internal shell and the outer shell and on the other hand by the strip-shaped wrapping region, the latching element formed by several profiles being provided on the outer wall of the outer shell and the engagement element being constituted by at least a locking nose provided at the front end of the wrapping part. Thus, in the mounted state, a partial region of the wrapping part can be placed in the intermediate space between the inner and outer shells, which advantageously makes it possible to obtain a very stable situation in the mounted state of the element

strip according to the invention.

  According to another embodiment of the invention, it is associated with the elastic internal shell and on its internal periphery another elastic shell comprising a front branch and an outlet part in the attachment region. In this case, three curved shell-shaped elements, the outer shell, the inner shell and the other shell, are arranged in an equidistant state against each other, which means that the cables to be maintained are retained way

optimal and securely fixed.

  According to the invention, there is also the possibility of connecting a bent elastic element to the internal periphery of the elastic internal shell above the fixing region, this element being for example in the form of S. When it acts to fix a large number of cables of various diameters, it is thus easily assured

  to have a reliable seat inside the strip element.

  According to another form of the invention, there is also the possibility of providing on the front side of the outer shell and the inner shell a rib connecting them, the wrapping part being formed in the form of a fork in a region partial, with two parallel branches and arranged in the intermediate space, on which the nose is provided -

  from the front side and through a bridge-shaped part.

  The branches are then placed in the intermediate space between the outer shell and the inner shell and thus make it possible to obtain

  a stable assembly in the assembled state.

  According to another form of the invention, there is also the possibility that the internal shell is extended on the end side which is opposite the front branch by an elastic element curved in the shape of an S. The shape of the assembly is then simplified without the operational safety of the strip element according to

the invention is degraded.

  It is already known from the state of the art, and as regards a retaining element intended for at least one tubular conduit, to constitute the retaining region by two shell-shaped fasteners having the form of an internal shell partially surrounding the periphery of the tubular pipe and by an external shell surrounding the internal shell at a certain distance from the latter (DE-PS 30 02 031). However, the two shells in this case have a common pressure region for the tubular pipe to be mounted and there is provided on the outer shell a lip covering the inner shell. It is therefore not possible to use this known construction to constitute and fulfill the function of

  the strip element according to the invention.

  The invention will now be described in more detail using the embodiments shown in the drawing in which: FIG. 1 shows an embodiment of the invention, shown in side view and in the open state; Figure la is a perspective view of the embodiment of Figure 1; Figure 1b is a front view of the embodiment of Figure la; FIG. 2 shows another possibility of implementing the invention, in side view with three regions in the form of equidistant shells; Figure 2a is a perspective view of the embodiment of Figure 2; Figure 3 is a side view of another embodiment of the invention; Figure 3a is a perspective view of the embodiment of Figure 3; Figures 4, 5 and 6 show various embodiments of

  the invention shown in side view and in perspective.

  The strip element according to the invention and intended to surround and hold objects which is shown in FIGS. 1, 1a and 1b consists essentially of a support region 1, a strip-like wrapping part 3, and a locking element 5 as well as a fixing region 6. The lower side of the fixing region 6 is formed in the form of a bottom plate and can be fixed for example by a T-bolt or by other elements to a

support.

  The support region 1 intended for the objects to be retained is constituted by a curved support part 2 which is connected to the wrapping part 3 by a thin intermediate region 9. The support part 2 which is curved is constituted by an internal shell

  elastic 7 and by a rigid external shell 8 surrounding the first.

  The elastic internal shell 7 is constituted by a flexible strip comprising hollow bodies 11 disposed at a certain distance from each other and directed against the internal side of the rigid external shell 8, these hollow bodies 11 having a trapezoidal shape in the mode of realization of Figures 1 and la. The inner shell and the outer shell 7 and 8 of the support region 1 are connected to each other by

  at least one rib 12, preferably in the attachment region 6.

  The wrapping part 3 is constituted by a profiled latching region 13 forming a meshing element 4 to which a gripping part 14 is connected. Opposite this wrapping element 3 is arranged the latching element 5 which is connected to the fixing region 6 by a curved collar 10. The engagement element 5 has two engagement noses 15 and 16 arranged one above the other diagonally and which are placed at the inside of the engagement element 5 so as to. ability to cooperate with the corresponding notch of the contoured engagement region 13 of the part

wrapping 3.

  To carry out the assembly, the strip element according to the invention is fixed on a support, for example by means of the fixing region 6 and for example by a fastener which is not shown and which is intended for its fixing on a support, or by pressing on a profiled lug. After this fixing of the strip element according to the invention on a support, the laying of the cables is started with small cables and corresponding cables are added in the different mounting positions. The strip element according to the invention then remains open until all the cables are laid correctly. It is only after closing is carried out by means of the gripping part 14, the profiled locking region 13 of the wrapping part 13 penetrating into the locking noses 15 and 16 of the latching element 5, which completes the assembly of the cables. As the elastic internal shell 7 is constituted in the form of a flexible strip comprising hollow bodies II arranged at a certain distance from each other and directed towards the internal side of the rigid external shell 8, and as these hollow bodies 11 are for example trapezoidal, we get this advantage that during assembly the hollow bodies are pressed outward against the inner side of

the outer shell 8.

  After assembly, the cables are held in the strip element according to the invention so as not to be able to slide and this perfectly avoids squeaking and clicking noises. Due to the cooperation between the profiled locking region 13 and the interlocking noses 15 and 16, there is the possibility of reliably maintaining in the strip element a more or less high number of cables of various diameters. By pressing the profiled latching region to release it from the latching noses 15 and 16, we can again open the entire element, remove the part

  wrapping 3 and remove the individual cables.

  It is also possible to use, instead of the hollow bodies 11, T-shaped support elements or other similar elements. There is also the possibility of providing the outer shell 8 with ribs

  internal peripherals which can be incorporated between the hollow bodies 11.

  A loose connection is thus obtained between the internal and external shells 7 and 8, which avoids a possible danger of damage during the

  mounting of small diameter cables.

  -7- In the embodiment of FIG. 2 and of FIG. 2a, the fixing region 6 is extended on the one hand by the support region 1 formed by the internal and external shells 7 "and 8 'and d "on the other hand by the wrapping part 3 'in the form of a strip. In this case, the support region 1 and the wrapping part 3' are face to face, and in the embodiment of FIGS. 2 and 2a , the fixing region est.munie of a clip connection 39. Above this clip connection 39 is provided a rib 12 which connects the inner shell 7 'to the outer shell 8' in their lower region. upper region, the two shells 7 'and 8' are joined together

to the other by a rib 19.

  Between the inner shell 7 'and the outer shell 8' is provided an intermediate space 18 which is dimensioned so that in the mounted state a partial region of the wrapping part 3 'can be introduced therein. To ensure this possibility of introduction, the wrapping part 3 ′ is formed in the form of a fork over a partial region, with two branches 20 and 21 in FIG. 2a which are parallel and which are arranged in the intermediate space 18. A bridge-shaped part is connected to these branches on the front side 22

  comprising in its center a snap-in nose 17.

  During assembly, the strip-shaped wrapping part is pushed by its two arms 20 and 21 into the intermediate space 18 between the inner shell 7 'and the outer shell 8' so that the rib 19 is arranged between the two branches 20 and 21 and constitutes a guide for them. The interlocking nose 17 then slides over the interlocking elements 5 'provided on the external periphery of the rigid external shell 8' until the cables located in the

  support region are firmly surrounded. This ends the editing.

  It can be seen in FIG. 2 and in FIG. 2a that the strip-like wrapping part 3 ′ is extended by a base part 27 which is bent upwards and is connected to the region of

fixing 6 of the strip element.

  In the embodiment of FIG. 2 and of FIG. 2a, it is associated with the elastic internal shell 7 'and on its internal periphery another elastic shell 23 comprising a front branch -8- 24 and an outlet part 25 in the attachment region 6. In this case there are three equidistant shells 23, 7 'and 8', ies two shells 23 and 7 'being elastic and allowing perfect fixing of cables

of various diameters.

  Above the fixing region 6 is provided at least one bent elastic tab 26 which is arranged in the space between the support region 1 and the base 27 of the wrapping part 3 '. This makes it possible to connect perfectly by means of the strip element according to the invention a large number of cables of different diameters or

objects to maintain.

  Whereas in the embodiment of FIG. 2 and of FIG. 2a, three half-shells 23, 7 'and 8' which are respectively at a certain distance from each other form the support region 1 of the strip element, the support region 1 of the embodiment of FIG. 3 and of FIG. 3a is constituted by two shells separated from each other by an intermediate space 18, these two shells

  being the flexible internal shell 7 'and the rigid external shell 8 ".

  In this case also, there is provided on the external side of the rigid external shell 8 "a profiled region having the shape of saw teeth which forms the engagement element 5". These interlocking elements 5 "are narrower in width as regards their sawtooth profile than the total width of the external wall of the external shell 8". The two shells 7 'and 8 "are also connected at their upper end by a rib 19 and in the fixing region 6

by the base part 27.

  Facing the support region 1 is again formed the wrapping part in the form of a strip 3 ′ which has at its front end a meshing part 4 ". This meshing part 4" is in the form of U , the interlocking noses being formed in the base region 31 of the U. In addition, two gripping regions 29 ′ and 20 are provided which are respectively arranged on the external surfaces of the branches 32 and 33 of the U in FIG. 3a . In this case also, a partial region of the strip-like wrapping part 3 ′ is constituted by two branches 20 and 21 which are parallel and at a certain distance from each other. The distance between the arms 20 and 21 is such that they can be introduced into the intermediate space 18 between the internal shell 7 'and the external shell 8 "; the rib 19 is also slightly narrower than the intermediate space located between the two branches 20 and 21 of the game

  wrapping tape 3.

  At the internal periphery of the elastic internal shell 7 ′ is connected above the fixing region 6 a curved elastic element 28 which is preferably in the form of S. This makes it possible to maintain

  perfectly assembled cables of different diameters.

  To carry out the mounting and after the fixing of the strip element of the invention on a support in the fixing region 6, the appropriate number of cables is introduced into the support region 1, and after having put all the cables, the engagement part 4 "is pushed by gripping the two gripping regions 29 and 30 in the intermediate space 18 between the elastic internal shell 7 'and the rigid external shell 8", and a partial region of the part elastic wrapping 3 'formed by the two branches 20 and 21 is therefore arranged in the intermediate space 18, and when the assembly is complete, the locking noses 17 are engaged in a notch of the sawtooth profile of the latching element ". There is also the possibility with this embodiment of providing an elastic S-shaped element 28 ensuring better

  still fixing cables to maintain.

  The embodiment of FIG. 4 is similar to that of FIG. 3 and of FIG. 3a, but the engagement element 4 ′ is constituted in a similar manner to that of the embodiment of FIG. 2 and of the figure. 2a and thus constitutes a part in shape of stirrup 22 with an interlocking nose 17 in the center. The fixing region 6 comprises a fixing element 37 which can be inserted, for example, into a corresponding opening in the support, not shown.

and be attached to it.

  The support region 1 is constituted in this case also by a bent elastic inner shell 7 'and by an outer shell

- 10 -

  rigid 8 "which surrounds it, and which are connected to each other in the front region by a rib 19. On its external housing, the rigid external shell 8" also has a sawtooth profile of

the locking element 5 ".

  The embodiment of FIG. 5 is very similar to the embodiment of FIG. 4, and only the fixing region 6 comprises a clipping element 37 known per se as a connection, with two elastic branches and a central region rigid. On the upper side is provided an elastic lip such that the whole device can be clipped into an opening of a support formed in an appropriate manner, the two branches of the link 37 of the fixing region 6 being arranged at the rear. of the support opening. In the embodiment of FIG. 6, the support region I is again constituted by an elastic and curved internal shell

  7 "and by a rigid external shell 8" surrounding the first.

  However, the internal shell 7 "is extended at its end which is opposite the front branch 19 by a bent elastic element in the form of an S 34. Another is provided between the internal shell 7" and the external shell 8 " rib 35 in the transition region with this elastic element 34. The attachment region 6 again comprises a lug-shaped part constituting a connection element with a support opening which is not shown. 'support i is the wrapping part in the form of a band 3' which is always provided on its front side with a meshing part 4 "

  similar to the construction of Figure 3 and Figure 3a.

  Overall, we obtain a strip element for surrounding and holding objects, which is constituted so that it can be used practically universally with a more or less large number of cables of various diameters in view of their maintenance and their fixing, the support region 1 for the objects to be maintained being respectively constituted by a curved support part 2, which is formed by an elastic internal shell 7 ', 7 "and

  a rigid external shell 8, 8 ′ or 8 "surrounding the first.

  In the embodiments of FIGS. 2 to 6, an additional advantage is obtained from the fact that the wrapping part 3 ′ is arranged in the intermediate space 18 and that unwanted noise is thus avoided and that in in addition, no protruding entry element

is a nuisance.
