Description

The invention relates to a cable tie with a head and at least one cable strap, the head being fixed to a head end of the cable strap, at least one locking means and a contact surface opposite the locking means being arranged in a recess penetrating the head, the cable strap having an insertion section and a the head end of the cable tie opposite tape end, wherein the cable tape can be inserted into the recess with the insertion section first and a loop is formed by the inserted cable tape, wherein when the cable tape is inserted into the recess, a contact side of the cable tape opposite a blocking side of the cable tape with the Contact surface in contact and the blocking means can be brought into operative connection with the blocking side, so that a shifting of the cable tie against an insertion direction through the blocking side, the blocking means and the contact surface is prevented.

Cable ties were originally developed in order to be able to fasten cables arranged in the cable harnesses of aircraft to one another in a simple manner. Before the invention of the cable tie, it was customary for the individual cables of a cable harness to be tied or tied with wire or wax tape using a technically demanding process. Nowadays, cable ties are a widely used connection element, for example to temporarily or permanently fix cables, hoses or the like at a laying location.

Both in the private sector and in a variety of professional fields of application, for example in mechanical engineering, in the electrical industry, but also in the construction industry, cable ties are used to solve a variety of constructional problems. Due to the very wide range of applications for cable ties, they have been developed into a large number of designs.

Despite the great variety of cable ties for a wide variety of fields of application, the known embodiments of cable ties still have some serious inadequacies. A large number of cable ties have a straight cable strap which has to be bent by a user before the cable strap can be passed through the head of the cable tie. So that a correct locking can take place, the cable strap has to be bent in a certain direction in the majority of the known cable ties, since otherwise no locking means can be brought into operative connection with the locking side of the cable strap. However, due to the external design of the known cable ties, it is often difficult for the user to see in which direction the cable tie must be bent correctly, so that a large number of cable ties are initially bent incorrectly by the users and correct locking cannot take place.

Another disadvantage of the known cable ties is that they are not optimized for one-handed operation. Especially when using cable ties in hard-to-reach places, for example in cable ducts or server cabinets, the use of the cable ties known from the prior art usually requires handling them with two hands and always a high degree of tact and / or experience.

The object of the present invention is therefore to provide a cable tie whose operation is simplified and which also enables one-handed use.

This object is achieved according to the invention in that the cable strap has a curvature, the strap end of the cable strap being spaced by the curvature a maximum of 20 mm, preferably a maximum of 10 mm and particularly preferably a maximum of 5 mm from an insertion opening of the recess, one at the strap end of the Cable tie applied to the cable tie tangent is directed in the direction of the insertion opening, so that by compressing the curved cable tie, the insertion section of the cable tie is inserted between the contact surface and the locking means in the recess and the cable tie by a further compression of the cable tie and thereby caused in Bring an operative connection of the locking side with the locking means can be locked. It is provided that in the cable tie according to the invention, due to the curvature of the cable strap, the insertion section is arranged and aligned with the insertion opening such that the insertion section is inserted into the insertion opening when the cable strap is compressed. In order to be able to adapt the cable tie to different uses, it is also possible and provided according to the invention that the cable strap can have a large number of different curved shapes, for example that of a substantially circular loop. Furthermore, it is also possible and provided that the shape of the loop can be adapted to objects to be encompassed by the loop and secured to one another by the cable tie, for example cables of a cable bundle, for example by reshaping an outer contour of the objects using the cable strap.

The invention makes use of the knowledge that the commercially available cable ties are not designed in terms of their shape to be as simple as possible to use. Most cable ties have a flat cable band which must first be bent in order to then thread the free end of the cable band into the insertion opening on the cable head, usually with two hands. The use of such cable ties in inaccessible places or in connection with objects that have to be held or positioned with a cable tie during the intended fastening is made considerably more difficult, so that the effort required for assembly is comparatively high and the cable tie can sometimes even be fastened with two hands cannot be easily carried out. Even those cable ties that have a curved cable band often do not facilitate the introduction of the free end of the cable band into the insertion opening on the cable head and cannot easily be fitted.

In order to facilitate the use and assembly of a cable tie, it is primarily provided according to the invention that the cable strap is curved and aligned in the area of the free strap end so that the strap end is only a short distance from the insertion opening in the cable head and when the cable is pressed together the curved cable band shaped and almost closed loop, the end of the band is almost automatically pressed into the insertion opening of the cable head and can be fixed therein. In this way, a particularly simple actuation of the cable tie is made possible, with the cable tie often being able to be held with only one hand and then initially compressed and then drawn.

Various variants and configurations are conceivable for the configuration of the locking means and the contact surface. The contact surface for its part can also have a locking means and the cable strap can be configured on opposite sides so that the strap end of the cable strap can be inserted into the insertion opening in any desired orientation and can be fixed therein. Nevertheless, the cable strap is expediently shaped in such a way that the strap end is inserted into the insertion opening with an orientation that is advantageous for the desired locking effect if the strap end is displaced in the direction of the insertion opening.

The cable tie according to the invention allows a particularly simple and quick assembly of the cable tie, for example to fix an object such as a cable on a cable harness or cable cabinet or to fasten a large-format poster to a mast. In many cases, by appropriately specifying a size or curvature of the cable strap, one-handed use and fixing of the cable tie can also be made possible. This makes it much easier to use the cable tie in inaccessible places or in connection with large or heavy objects.

Regardless of the shape of the cable tie, it is provided according to the invention that the tape end is arranged a maximum of 20 mm away from the insertion opening when the cable tie is free of load and not locked. In order to enable the cable tie according to the invention to be operated as simply as possible, provision is made for a distance between the end of the tape and the insertion opening to be as small as possible. Depending on the planned use of the cable tie, however, it can also make sense that a usage-dependent minimum distance between the end of the tape and the insertion opening is not fallen short of, for example in order to have sufficient play when positioning the cable tie so that the risk of unintentional locking of the cable tie is reduced . Overall, such a configuration of the cable tie according to the invention ensures that the cable tie can be locked with one hand after it has been prepositioned, for example around a bundle of cables to be tied together.

The cable tie according to the invention is in particular also intended and suitable for use as a one-way restraint, for example by security forces such as the police, customs or judicial authorities. For this purpose, it is possible and provided according to the invention that the cable tie can also have a head with a plurality of recesses and associated cable ties in order, for example, to fix the arms of a person to one another by means of a single cable tie according to the invention and to tie the person up, or around the person to be able to attach to an object, for example a fence, and thus to immobilize it.

It is also possible that the cable tie according to the invention can have a single recess with locking means arranged opposite one another. In a cable tie according to the invention designed in this way, it is provided that the cable ties rest against one another when the cable tie is locked, so that the contact surface for the second cable tie is formed by the contact side of the first cable tie and vice versa, the locking side of the first cable tie being brought into operative connection with a first locking means and wherein the locking side of the second cable strap is brought into operative connection with a second locking means, which is opposite the first locking means.

In order to be able to adapt the cable tie to a wide variety of requirements, it is According to the invention, it is provided that the cable tie can be made from a variety of different materials. Like the known cable ties, the cable tie according to the invention can also be made from a plastic, for example polyamide, in particular polyamide 6.6 or polyurethane. In addition, the cable tie according to the invention can also be made from a metal, for example a stainless steel, but also from a combination of different materials. In order to meet special requirements and also to be able to withstand extraordinary loads and / or environmental influences, it is provided according to the invention that the cable tie can be made from a variety of different materials, for example from a plastic, from fiber materials, from glass fibers, from metals Natural substances, made from compostable materials and from recycled materials.

An advantageous embodiment of the invention provides that at least one locking means is formed on the locking side of the cable strap, at least one locking means being designed as a locking tongue and wherein the locking means can be brought into engagement with the locking tongue when the cable strap is inserted into the recess, so that a displacement of the cable tie against the insertion direction by the locking tongue, the locking means and the contact surface is prevented. In order to be able to use the cable tie according to the invention to form loops with different diameters and to be able to use the cable tie to attach the widest possible range of objects to one another, it is provided that a large number of similar locking means can be arranged on the locking side of the cable tie. Depending on how far the cable tie is pulled, the last locking means that has come into engagement with the locking tongue holds the cable strap in position and prevents the cable strap from being shifted against the direction of insertion.

A cable tie according to the invention configured in this way can be produced particularly inexpensively from a plastic. In order to increase the load capacity and resistance of the cable tie according to the invention, it can also be made entirely or partially from a metal. In order to achieve optimal tensile strength with the lowest possible manufacturing costs, it is possible and provided according to the invention that the cable strap and the head of the cable tie can be made of a plastic, whereby the locking means designed as a locking tongue can be made of a metallic material, for example stainless steel.

An advantageous implementation of the inventive idea provides that at least one of the locking means is designed as a clamping element, the clamping element exerting a clamping force on the cable strap inserted into the recess and arranged between the clamping element and the contact surface as soon as it is displaced against the insertion direction, so that a displacement of the cable strap against the insertion direction by the clamping element and the contact surface is prevented and the cable strap is fixed in the recess in a clamping manner. Such a configuration of the cable tie makes it possible that the locking side of the cable tie can be designed to be essentially smooth and that no separate locking means have to be arranged on the locking side of the cable tie. A smooth design of the blocking side is particularly advantageous when the cable tie according to the invention has to be passed through narrow spaces for assembly, or when particularly sensitive objects are to be secured to one another by means of the cable tie, for example particularly pressure-sensitive cables. In addition, a cable strap with a smooth locking side is advantageous if the cable tie according to the invention is used as a disposable restraint, since this reduces the risk of injury to a person who is tied up in the area of a tie produced by means of the cable tie.

In an advantageous embodiment of the cable tie according to the invention, it is provided that the clamping element has a clamping body that is essentially spherical or cylindrical. It is provided that the clamping body is arranged within the recess in such a way that the clamping body exerts a clamping force on the cable strap inserted into the recess between the clamping body and the contact surface as soon as the cable strap is displaced against the insertion direction. For this purpose, it is provided that the spherical or cylindrical clamping body can be contacted with the locking side of the cable strap when the cable strap is inserted into the recess, the clamping body being displaced by the cable strap in the direction of the contact surface when the cable strap is shifted against the insertion direction, so that the cable strap is pressed against the contact surface by the clamping body.

In all embodiments of the cable tie according to the invention it is provided that the locking means can also have an unlocking device by means of which a locking of the cable tie can be released. In the case of a locking means designed as a locking tongue, it is provided that the unlocking device can for example comprise a lever, by means of which the engagement between the locking tongue and the locking means can be released. In the case of a locking means designed as a clamping element, it is provided that the unlocking device can be designed such that a Contact between the clamping body and the blocking side of the cable tie can be canceled, so that the clamping element no longer applies a clamping force to the cable tie of the cable tie according to the invention.

It is provided that the insertion section of the cable tie of the cable tie according to the invention can be designed both curved and free of curvature. A slight curvature or a curvature-free design of the insertion section facilitates the manual insertion of the insertion section into the recess of the cable tie.
