Description

Press socket for attaching components to a flexible strand

field of invention

The invention relates to a press socket for clamping a blunt end of a flexible strand, such as a rope, cable or rope, the press socket having a ribbing and containing a compression ring for attaching further components to the rope end and the press socket being set up so that the Press mount deformed when force is applied from the outside and so between the material of the flexible strand a form fit is generated. The compression ring is deformed together with the press fitting when external force is applied. The invention further relates to a flexible strand which has a press fitting according to the invention at at least one end. The crimped socket at the at least one end of the flexible strand may have a further component, the further component comprising a foot which is crimped in the crimped socket together with the end of the flexible strand. The press fitting according to the invention is primarily suitable for undetachably clamping the blunt ends of cables, ropes or ropes made of plastic materials, with the positive fit between the material of the cable, rope or rope and the press fitting with the crush ring surprisingly withstanding very high pull-out forces. The press fitting according to the invention and flexible strands provided with it are particularly suitable for the production of safety ropes for transportable objects which have an integrated lock, such as bicycle locks. Furthermore, the invention relates to a method for attaching the press fitting to blunt ends of flexible strands.

Background of the Invention

A type of rope commonly used today consists of braided synthetic fibers. Synthetic ropes are very beneficial because they are lightweight, strong, and very flexible. Plastics are also resistant to the effects of water and weather. Wear and tear from water and weather. Therefore, water sports activities, such as tying boats to a dock or winter sports activities, plastic ropes are often used. Increasingly, plastic ropes are also being used as a component of security strands for mobile objects, such as bicycle locks, for example. However, plastic ropes are very smooth and slippery or slippery. A problem with the use of braided plastic ropes is to attach components, such as evil or locking bolts, to the rope ends in such a way that these components are not detachably connected to the rope ends or withstand high pull-out forces. The use of press mounts is known, for example, for attachment to cable ends of steel cables. WO 2011/103640 and US 2015/0132050 disclose therein

Connection a press socket, which contains an inner lining made of a deformable material such as aluminum, wherein this inner lining deforms when pressing the press socket to the steel cable and thereby the press socket is attached to the steel cable. Due to the smooth surface of plastic cables, the press fittings disclosed in WO 2011/103640 and US 2015/0132050 are not suitable for producing a non-detachable attachment to the ends of the plastic cables.

US Pat. No. 4,455,717 and US Pat. No. 4,157,602 disclose the use of press fittings to produce loops on rope ends. One end of the rope is laid as a loop and attached to the same end of the rope with the help of the press fitting. However, the embodiments shown here are not suitable for creating non-detachable connections on blunt rope ends, in particular on ropes made of plastic.

DE 94 07 461 U1 describes a rather complicated structure for attaching a hook to the end of an expander rope, rubber rope or the like, the hook having a foot piece which overlaps the free end of the rope with clamping elements and a head piece which overlaps the foot piece, characterized in that the hook foot piece and hook head piece are provided with screw threads, wherein the clamping elements can be driven into the free end of the rope when screwing. The same applies to DE 92 05 945 U1, which also deals with the attachment of a hook to a rope end, the hook having a foot part and in the foot part a clamp of the rope end formed by two pincer elements that can be narrowed by force between the pliers elements serving clamping groove is formed, and that a locking part for locking the pliers elements in the clamping connection with the cable end is arranged on the pliers elements.

US Pat. No. 5,706,679 A relates to a bicycle lock which proposes a combination of a U-lock with a cord lock. The strand lock can consist of any suitable flexible material, but a cable or a chain is preferred. The cable ends are secured by crimping into aluminum sleeves, which have a recess to accommodate a bolt that allows the aluminum sleeve to be rotatably connected to a lock body. Based on the state of the art, the invention was based on the object of providing a device for fastening components to the butt ends of flexible strands, which is simple in construction, easy to attach and suitable for producing non-detachable connections, particularly at the ends of plastic cables.

Description of the invention

The object of the invention is achieved by a press socket for clamping a blunt end of a flexible strand according to claim 1, characterized in that the press socket has an internal structure in the form of a corrugation and a crush ring, the press socket being set up so that the press socket and the crush ring deforms when force is applied from the outside and a form fit is created between the material of the rope or rope.

The press fitting is preferably designed in one piece and is therefore easy to produce and attachable to the blunt ends of flexible strands in a simple manner. In any case, the crush ring is designed as a separate part. In cross section, the press socket preferably has an annular or elliptical shape. The corrugation is also elliptical or ring-shaped according to the cross-sectional shape of the press mount and is arranged circumferentially inside the press mount. In one embodiment, the corrugation has 1-10, preferably 2-9 or 3-8, particularly preferably 4-7, 4-6 or 4-5 corrugations. The corrugations are designed in such a way that damage to the end of a flexible strand, such as the corrugations cutting into the flexible strand, is avoided when the press fitting is pressed on.

It has also proven to be advantageous if the corrugations of the press fitting have barbs which prevent the flexible strand from slipping out of the press fitting under high loads.

In a particularly preferred embodiment, the invention provides a press socket for clamping a blunt end of a flexible strand, characterized in that the press socket has an internal structure in the form of a corrugation and a crush ring for connecting further components to an end of the flexible strand, wherein the further components have a foot arranged to interact with the crush ring; wherein the base of a further component has a circumferential groove which interacts with an opening in the compression ring provided for this purpose; the compression fitting and the compression ring are set up such that the compression fitting and the compression ring deform when force is applied from the outside, and a form fit is produced between the material of the flexible strand and the compression fitting.

The press mount according to the invention with the described internal structure is particularly advantageous since the form fit between the material of the flexible strand and the press mount withstands pull-out forces of 10 kN and more, preferably 15 kN and more, particularly preferably 20 kN and more. This is sufficient, for example, if the flexible strand with press fittings according to the invention is used as a safety cable for securing or fastening portable objects, such as a bicycle lock.

The press mount according to the invention and the squeeze ring are preferably made of a material that can be deformed by pressing, but still has sufficient strength and stability for the production of a non-detachable connection with the flexible strand. It has proven particularly advantageous if the press fitting consists of a metal, preferably selected from steel, stainless steel, copper or a metal alloy. Suitable metal alloys are, for example, bronze, brass or iron alloys. Press mount and compression ring can be made of the same material or different materials. The press fitting and the compression ring are preferably made of the same material.

A “non-detachable connection” is understood in the context of the invention to mean that the connection between the press fitting and the material of the flexible strand, which also has a press ring and/or another component with a foot, cannot be separated or released again without being destroyed.

In a further embodiment of the invention, the press socket can have an opening for receiving a fastener, as a result of which the press socket can be connected to a housing, for example the housing of a locking device. Suitable fasteners are screws, rivets, bolts or straight pins. Particularly preferred for the production of non-detachable connections with the housing are fasteners that are the intended opening of the press socket can be pressed, ie particularly preferred fastening means are bolts or straight pins.

As mentioned, the press socket according to the invention contains a crush ring. The outer shape of the compression ring corresponds to the inner shape of the press mount, i.e. it is ring-shaped or elliptical. The crush ring is used to attach other components to an end of a flexible cord, as will be described below.

A further aspect of the invention relates to a flexible strand which has a press fitting according to the invention at at least one end, preferably at both ends. For use for a wide variety of purposes, the flexible strand can have a further component at the end having the press fitting. For attachment to the distal end of the press mount, the other components are equipped with a foot that is set up in such a way that it interacts with the compression ring. In the simplest case, the base of a further component has a circumferential groove which interacts with an opening in the compression ring provided for this purpose. To attach a further component to one end of a flexible strand, the base of a further component is inserted into the distal opening of the press socket and the compression ring with its opening is inserted into the groove of the base provided for this purpose. When a press fitting is pressed onto the end of the strand, the press fitting and the compression ring deform. As a result, another component can be attached to one end of a flexible strand in a very simple manner by pressing them together in a non-detachable manner. By interacting with the groove at the base of the additional component, the compression ring prevents it from slipping out of the press fitting. The press mount according to the invention is therefore particularly advantageous since the press mount is intended to accommodate a further component in a simple manner in order to provide the flexible strand with functions.

The base of the additional component has a shaft, a groove and an end region of the shaft at its proximal end, which is inserted into the press socket. It has proven to be expedient if the shank and the end area of the shank have the same diameter. In one aspect, the invention thus relates to a crush ring with an elliptical or annular outer shape, having an opening for cooperation with a groove of a foot of another component.

The size of the inner area of the opening of the squeeze ring is designed so that it essentially fits the groove of the foot of the further component, i.e. the width of the inner area of the opening of the squeeze ring is only slightly larger than the size in the circular design for example the diameter of the groove. The width of the opening of the compression ring is preferably 0.01 to 0.5 mm larger than the size, for example the diameter in the case of a circular design, of the groove. It has proven advantageous if the width of the opening of the squeeze ring is 0.02 to 0.4 mm, 0.03 to 0.3 mm, 0.04 to 0.2 mm or 0.05 to 0.1 mm larger is than the size, in the case of a circular design, for example the diameter, of the groove. The opening can have an enlargement on the outer edge to simplify handling when the compression ring is pushed onto the groove of the foot of another component.

The same applies to the material thickness, i.e. the thickness of the compression ring in relation to the width of the groove. The thickness of the compression ring is designed in such a way that it essentially fits exactly to the width of the groove of the foot of the further component, i.e. the thickness of the compression ring is only slightly greater than the width of the groove. Preferably, the thickness of the crush ring is 0.01 to 0.5 mm greater than the width of the groove. It has proven to be advantageous if the thickness of the compression ring is 0.02 to 0.4 mm, 0.03 to 0.3 mm, 0.04 to 0.2 mm or 0.05 to 0.1 mm greater than the width of the groove.

It is particularly preferred if the play between the opening of the squeeze ring and the groove of the base of the further component is as small as possible in relation to all previously discussed dimensions of the squeeze ring and the groove of the base of the further component prior to pressing in the press socket. In order to further reduce the play, the squeeze ring can have elevations on the outer edge which are substantially evenly distributed over the closed part of the edge of the squeeze ring. This achieves a sufficient attachment of the further component to the desired end of the flexible strand.

Examples of other components that can be attached to an end of a flexible cord are selected from eyelets, snap-in bolts, mate bolts or any other type of functional means. It is particularly preferred if the further component is formed in one piece with the respective functional unit and the foot.

Depending on the strength and resilience requirements, the further component is preferably made of a metal, particularly preferably selected from steel, stainless steel, copper or a metal alloy such as bronze, brass or an iron alloy.

In a further aspect, the invention relates to an arrangement comprising a press socket according to the invention, a squeeze ring and a further component, the press socket and the squeeze ring interacting with a foot of the further component in such a way that the further component can be attached to one end of a flexible strand.

In the arrangement according to the invention, the further component, the compression ring and the press fitting have the properties and structure as described above.

In a further embodiment of the invention, the press fitting also has a circumferential collar. This circumferential collar is preferably directed inwards and is preferably located at the distal end of the press socket. The shape of the collar corresponds to the shape of the cross section of the press socket and is, for example, circular or elliptical. The circumferential collar acts as an additional means of restraint for the base of additional components in the press fitting, which are provided with the inventive crush ring and which can be attached to the end of the flexible strand.

The flexible strand, which can be permanently connected to a press fitting according to the invention, preferably contains metal fibers, synthetic fiber material, natural fibers or a mixture of these fibers.

Within the meaning of the invention, a flexible strand is understood to mean a rope, a cable or a rope. It is particularly preferred if the flexible line is a safety cable or safety line for objects that can be moved, for example with the aim of preventing theft.

Safety ropes or safety strands are used in practice, for example, in cable locks for two-wheeled vehicles. Particularly suitable safety ropes or safety strands are described, for example, in WO2019/115430. According to this, a suitable safety rope for securing objects is characterized in that

• the safety rope has three, four or more scrims, braids or fabrics made of fibers or yarns,

• wherein the braids or weaves are arranged one on top of the other,

• and the safety rope can optionally have a chain as the core.

This construction of the lifeline ensures both improved protection against mechanical impact, wwiiee saws, bolt cutters, tearing or diamond tools due to the presence of the three, four or more braids or weaves of fibers or yarns, as well as improved cut resistance against sharp-edged objects such as knives, due to the presence of the chain. The choice of materials used to manufacture the scrims, braids or fabrics also enables effective protection against the effects of heat and cold.

A non-crimp fabric is a textile fabric that consists of one or more layers of parallel, stretched threads. The threads are usually fixed at the crossing points. The fixation takes place either by material connection or mechanically by friction and/or form fit. Non-crimp fabrics can be single-layer or multi-layer. The thread layers in multi-layer scrims can all have different orientations and also consist of different thread densities and different thread counts. in the

In contrast to woven fabrics, non-crimp fabrics have better mechanical properties as reinforcement structures in fiber-plastic composites, since the threads are in a stretched form and therefore there is no additional structural elongation and the orientation of the threads can be specifically defined for the respective application.

Typically, the scrims for use in the lifeline are aligned in parallel or are stranded.

Braids consist of several regularly intertwined strands, such as fibers, yarn, metal wires, etc.. Typically, the braids for use in the lifeline of the present invention are formed as tubular layers.

With regard to the type of material of the fibers or yarns, the same applies to the scrims, braids or fabrics from which the sleeve-like or tubular layers of the safety rope according to the invention are made.

The fibers or yarns for the formation of the scrims, braids and/or fabrics of the safety strand are preferably selected from chemical fibers and natural fibers or yarns made from them.

Preferred chemical fibers for use in the individual layers of the safety rope are selected from fibers made from natural polymers, fibers made from synthetic polymers, fibers made from inorganic substances and metal fibers.

In one embodiment, the natural polymer fibers are selected from regenerated cellulosic fibers such as viscose, modal, lycocell and cupro; fibers of cellulose esters such as acetate fibers and triacetate fibers; protein fibers such as regenerated protein fibers, modified soybean protein fibers, zein fibers, casein fibers and artificial spider fibers; Polylactide fibres, alginate fibres, chitin fibres, elastodiene fibres, and bio-based polyimide fibres.

In another embodiment, the synthetic polymer fibers are selected from fibers of polyester, such as polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), and polybutylene terephthalate (PBT); Polyamide (PA), polyimide, polyamideimide, aramid, polyacrylic, modacrylic, polytetrafluoroethylene (PTFE), polyethylene (PE), polypropylene (PP, polychloride, elastane, polybenzoxazole, polybenzimidazole, polyurea, melamine, polyphenylene sulfide, trivynil, elastolefin, elastomultiester, polyvinyl alcohol , vinylal, polycarbonate, and polystyrene.

In a further embodiment, the inorganic material fibers are selected from ceramic fibers, quartz fibers, glass fibers, basalt fibers, carbon fibers, boron fibers, crystal fibers, slag fibers and nanotube fibers. In another embodiment, the fibers or yarns are selected from polyester fibers (PES), aramid fibers, glass fibers and high modulus polyethylene (HMPE) fibers.

It is particularly preferred if the laid, braided and/or woven fabrics contain mixtures or combinations of the fibers or yarns described above.

In a further embodiment, the safety cable according to the invention or the safety line according to the invention contains a chain. The chain is preferably arranged centrally inside the safety cable or safety line. The chain can be made of different materials, for example metal or plastic.

In a preferred embodiment, the chain is made of metal, such as steel, hardened steel, galvanized steel, stainless steel, titanium, aluminum or a metal alloy.

In a likewise preferred embodiment of the invention, the chain consists of plastic or a composite material. Suitable composite materials are, for example, metal-plastic composite materials, fiber-reinforced or glass-containing composite materials.

In one embodiment, the safety rope also has a sheathing that is preferably designed to be UV-impermeable. In addition, the casing can comprise a plastic material, in particular Teflon, acrylic and/or silicone. This effectively protects the textile fibers from the weather. In addition, this sheathing also holds textile fibers protruding from the fiber composite together. Additional textile fibres, scrims, braids or fabrics can be arranged over the sheathing, which do not necessarily have to fulfill security aspects, but can be printed on to give the strand lock a special graphic design. Alternatively, the sheathing can be printed or color-matched to achieve a desired design.

In a further embodiment, the weather-resistant casing or overlying textile fibers, scrims, braids or fabrics can be designed in such a way that additional safety aspects, for example improved road safety, are ensured. For this purpose, the casing can be equipped with reflective optical elements. Suitable optical elements are known per se and can be selected from lenses or prisms or spheres embedded in the cladding or combinations thereof. Alternatively, a plastic layer containing such optical elements can be arranged on the textile fibers, scrims, braids or fabrics lying over the sheathing.

A further advantageous embodiment of the safety rope consists in the fact that a metallic layer can be arranged between each scrim, mesh or fabric layer. The metallic layer preferably contains metal wires or metal foil. Alternatively, the textile fibers can also be provided with a metallic coating, with the metallic layer being in particular closed. This arrangement of the metallic layers is particularly advantageous and increases the flame resistance of the safety rope. However, non-closed layers can also be present, which in particular have a single wire that is advantageously laid in a spiral shape. This arrangement also helps to improve flame resistance, but in particular increases the tensile, cut and tear resistance of the lifeline.

In a further preferred embodiment, the sheathing of the safety rope can contain abrasive substances. Suitable abrasive substances are, for example, particles that are preferably selected from the group consisting of aluminum oxide, corundum, boron carbide, silicon dioxide, silicon carbide, sand and glass particles. Instead of or in addition to the sheath, the abrasive substances can be contained in layers that are additionally arranged between the individual scrim, mesh or fabric layers. These abrasive substances dull sharp tools when attempting to steal.

The sheathing or intermediate layers arranged between the individual scrim, mesh or fabric layers can contain further additives. Conductive substances, flame retardants, luminescent substances and metals can be contained as additives. The conductive substances can be selected from the group containing soot, carbon fibers, metal powder and nanoparticles, in particular carbon nanotubes. Combinations of these substances can also be used. Conductive substances can be used to equip the safety rope with smart functions or an electronic anti-theft device. Phosphates, borates, in particular ammonium polyphosphate, tris(tribromoneopentyl)phosphate, zinc borate or boric acid complexes of polyhydric alcohols are preferably used as flame retardants. These additives contribute to a increased protection of the safety rope against the effects of heat and fire. Fluorescent and/or phosphorescent substances on an inorganic or organic basis, in particular zinc sulfide and alkaline earth metal aluminates, are preferred as luminescent substances. These additives can contribute to increasing traffic safety (being seen in the dark).

In a further advantageous embodiment, the safety rope can have a water-repellent impregnation. The water-repellent impregnation is preferably applied to the outer casing. However, it is also possible to equip one or more of the non-crimp fabric, mesh or fabric layers with a water-repellent impregnation.

It is particularly preferred if the individual layers of scrims, braids and/or fabrics consist of or contain fibers and/or yarns of different materials. This allows optimal properties of the safety rope to be generated. For example, more interior layers may have high tensile strength and more exterior layers may have high cut, heat and cold resistance, respectively.

Intelligent securing of the strand lock is possible if at least one electrical conductor is arranged in the safety cable and alarm means are provided which trigger an alarm when the electrical conductor is severed. This alert could then be transmitted directly to an application of a mobile computer device, a mobile phone, a smartphone or a tablet PC using suitable transmission means.

In order to ensure protection against theft, the safety rope must be able to be connected to a suitable locking or safety device at both ends. In principle, all conventional locking devices that are used or can be used to prevent theft of movable objects are suitable. If the locking device is not attached directly to the safety rope, the safety rope preferably has further components or devices at both ends, with which a locking device, such as a padlock, can be connected. In one embodiment, the safety cable therefore has an eyelet at both ends. The eyelets can have different shapes and can be circular or O-shaped, for example. The eyelets can be formed by separate components, for example made of metal or, as described above for the chain, made of a composite material, which can be firmly connected to the respective end of the safety rope by means of the press fitting according to the invention. Steel eyelets are preferably used. Hardened steel eyelets are particularly preferred to improve anti-theft protection. To improve corrosion protection, the eyelets can be provided with corrosion-inhibiting coatings, such as a PVC coating. Alternatively, the eyelets can be galvanized. The size, especially the diameter of the eyelets can vary. Preferably, the eyelets of security ropes, which are used in the field of anti-theft protection for mobile objects, have an inside diameter in the range from 8 mm to 200 mm, preferably from 8 to 150 mm or from 8 to 100 mm, more preferably from 8 to 90 mm. 8 to 80 mm, 8 to 70 mm or 8 to 60 mm, particularly preferably from 8 to 50 mm, 8 to 40 mm, 8 to 30 mm or 8 to 20 mm.

It may be useful to connect the ends of the safety rope to a locking or safety device that is rigidly connected to the movable object. In a further embodiment, the safety rope can therefore have an eyelet or loop at one end and a suitable safety element at the other end, which can be locked in a locking or safety device permanently installed on the movable object. Objects could be secured by guiding the safety rope around the object, pulling the free end through the eyelet or loop and then locking the free end. Such a permanently installed locking or security device is, for example, a frame lock. The suitable safety element is selected, for example, from a bolt or a block, which is pressed firmly and undetachably into the press socket according to the invention at one end of the safety rope by means of a foot, as already described above.

Furthermore, it is preferred if the safety rope has parts of a locking or safety device at the ends, which interact with one another. Such locking devices are known to those skilled in the field of bicycle locks. In one embodiment of the invention, the locking or safety device is designed as a lock. In a preferred embodiment, the locking or safety device is designed as a lock that can be locked with a key. A combination lock is also conceivable as a locking device. The parts of the locking device that are attached to the ends of the Safety rope are attached are preferably by means of a foot, as already described above, firmly and inextricably pressed into the press socket according to the invention at one end of the safety rope.

The length of the safety rope of the invention can be selected differently according to the intended use. In the area of securing two-wheelers, lengths between 50 cm and 200 cm are suitable. Lengths between 50 cm and 160 cm, in particular between 50 cm and 100 cm, are particularly suitable. If other moving objects, such as boats, are to be secured, a correspondingly greater length of safety rope is selected. The same applies to the safety rope according to the invention in the field of industrial applications.

Accordingly, in a particularly preferred embodiment, the invention provides a safety rope for mobile objects, having a press socket according to the invention at a first end, the press socket being connected to a housing, for example a locking device, with the aid of a fastening means; and furthermore having at a second end a press fitting according to the invention with a further component, the further component being pressed together with the safety cable in the press fitting by means of a foot. The additional component is preferably selected from an eyelet, a snap-in bolt or a mate bolt.

In a particularly preferred embodiment, the safety rope according to the invention has a locking device with a locking cylinder in a housing which is accommodated in a protective cover.

In a further aspect, the invention relates to a method for producing a connection between a blunt end of a flexible strand and a press fitting according to the invention, characterized in that the method comprises the steps:

• inserting the end of the flexible strand into the proximal end of the ferrule;

• Application of force from the outside, with the press fitting being deformed in such a way that the ribbing of the press fitting engages in the material of the flexible strand and a positive connection is formed between the material of the flexible strand. To produce a non-detachable connection between the flexible strand and the press socket, it has proven to be advantageous if a pressure of 0.5 to 1.0 kN/cm ² is applied when the press socket is pressed against the flexible strand and if the diameter of the press socket is changed by deformation is reduced by approx. 3 to 8 mm.

In order to ensure that the form fit between the material of the flexible strand and the press fitting withstands pull-out forces of 10 kN and more, preferably 15 kN and more, particularly preferably 20 kN and more, in addition to the aforementioned parameters when pressing the press fitting on the flexible strand the diameter and the nature of the flexible strand are selected so that the flexible strand has sufficient resistance, i.e. sufficient strength to create the positive connection with the press fitting.

In a preferred embodiment of the method according to the invention, when a connection is made between a first end of a flexible strand and a press mount according to the invention, a further component, as described above, is simultaneously pressed in the press mount by means of a foot. In this case, the base of the further component preferably has a groove which interacts with a compression ring as described above, so that a non-detachable connection is formed between the further component and the flexible strand.

In a further preferred embodiment of the method according to the invention, the second end of a flexible strand is also connected to a press socket according to the invention, wherein, for use of the flexible strand in connection with a closing device, the second end of the flexible strand is connected to the press socket in the sleeve of a closing device is attached. The second end of the flexible strand is fastened to the press socket in the sleeve using a fastening means which can preferably be pressed into the opening in the press socket provided for this purpose. Suitable connection means that can be pressed in are preferably bolts or cylinder pins. In a particularly preferred embodiment, a bolt or cylindrical pin is inserted and pressed in completely continuously through the press mount. When the fastening means is pressed into the opening of the press mount provided for this purpose, the opening is deformed according to the invention in such a way that the press mount and the housing are permanently connected to one another.

The method according to the invention makes it possible in an advantageous manner for the housing to have a planar surface after the fastening means has been pressed in, which has no points of attack for pulling out the bolt or cylinder pin. When using such an attachment to a safety cable for portable objects, the theft stole security can be further improved.
