Description

The present invention relates to a holder / locking adapter for fixing a wire in a wire fastening in a sea arm / long arm in order to reduce or eliminate the risk of fatigue failure in the joint. The invention is primarily intended for use in prefabricated lamps in heavier commercial vehicles such as trucks and buses, but can of course also be used on other types of vehicles, such as for example passenger cars, construction machinery, boats, etc. in which wires are used to maneuver one or more of the vehicle's mechanical functions. The invention relates to a vehicle equipped with a holder / locking adapter according to the invention.

BACKGROUND ART Most vehicles on the market today are usually equipped with one or more mechanical functions that need to be operated manually via e.g. a wire arm or a rudder system. A wire is not used to transmit an axial traction to the ratchet arm or rudder system. The wire is usually connected to the sea arm or the link system via some form of wire attachment or connection. In certain applications, such as locks for externally placed tool hatches on heavy vehicles, during prolonged use and in unfavorable conditions, heavy wear occurs in the joint, which can eventually lead to material breakage due to fatigue in the metal in some of the joint components. The shell may be that the lock and the wire connection have been subjected to harsh handling when opening and e.g. closing the door, rapid and powerful shocks during the closing movement, perhaps repeated many times a day.

This wears on the wire fastener and other components in the locking mechanism and repairs of such damage often mean that the entire wire with wire fastener and casing must be replaced. In order to be able to carry out this measure, it is often required that parts of the body or parts of the cab's interior and / or other components must be dismantled in the vehicle and then reassembled after the wire has been replaced with a new one. long time and thus becomes costly for the vehicle sawmill. For this reason, it is advisable to reduce or eliminate the risk of fatigue failure in the connection between the wire and the seawater / shore system.

When manufacturing / assembling the vehicle, it is important that the handling of the components is simple and thus cost-effective, apart from the fact that the parts themselves should be cheap to manufacture and stock, in addition to the fact that they must fulfill the intended function in a good and reliable manner.

The locks and their components must be mounted in such a way that they are securely attached to the vehicle's chassis at the intended location, even under occasionally difficult operating conditions, on a really uneven surface, e.g. when the vehicle or if the vehicle has been subjected to an accident. It is a disadvantage that previously known joints are not sufficiently shock-absorbing, which is why the function of the mechanical structure is compromised or worn over time in an unfavorable manner.

In addition, the lock must of course always be easy to open and its maneuvering wire should be guided easily in the bandage but without a large gap and it is an advantage if the bandage is easily accessible for any maintenance measures.

Many attempts have been made in the past to solve these problems and to propose a design which is reliable, but which is inexpensive to manufacture and at the same time allows a quick and easy assembly.

US6543821 shows, for example, a locking device which contains a number of couplings and links. Figure 20 in this document shows a long arm which is actuated by a shaft mounted in a cylindrical coupling element provided in one spirit with a single head. By inserting a shaft or rod through a hole in the connecting element, this is locked to the sea arm. Screw the locking coupling element to the shaft or rod. There is a risk that the screw loses its grip after a while, especially during hard handling, or that the wire wears in the area of the screw's engagement with the wire.

US2002 / 0056296 shows a similar example of a locking device which contains similar couplings and links. Also on a connecting element which connects has shown, in figure 10, a shaft / rod with a sea arm. This construction has approximately the same disadvantages as US6543821.

Kand technology does not show any wire fastening / connection as a precursor to the present invention and which in a simple and cost-effective manner contributes to facilitating assembly and at the same time reduces or eliminates the risk of fatigue failure in the wire fastening.

SUMMARY OF THE INVENTION An object of the invention is to solve the above-mentioned problems and to demonstrate a joint comprising a holder / locking adapter for simple and things fixing of a wire in a sea arm or in a link system.

A further object of the invention is that the holder / locking adapter should be able to be mounted in a simple manner without tools when assembling the construction.

A further object of the invention is that the control / wire can be mounted in a single manufacturing step.

A further object of the invention is that the holder / lock adapter must be able to be mounted in such a way that the wire does not risk coming loose with time.

A further object of the invention is that the holder / lock adapter automatically fixes / locks the wire to the sea arm / link system when the wire is rotated and mounted in its operative position.

A further object of the invention is that the holder should be simple in its construction and consist of a single part which can be cast in one piece.

A further object of the invention is that the holder / lock adapter should have a low weight and be light and inexpensive to manufacture.

These and further objects and advantages are achieved according to the invention by a device defined by the features set forth in the characterizing part of the independent claim 1.

The invention is primarily intended for heavier commercial vehicles such as trucks, buses and the like, but of course can also be used in other types of vehicles or in other applications where a wire is connected to some form of sea arm or shear system for transmitting a traction force.

An important object of the invention is to ensure the function of the dressing for a long time and at the same time allow easy assembly so that the composition during manufacture becomes both time and cost effective.

The invention is achieved by using a connected enclosing single holder / locking device used in the mounting of the spring heater or the link systems.

The holder / locking device is advantageously made of, for example, a plastic material such as POM, EPDM or the like and is provided with a notch intended to accommodate the outer end of the lever and the part of the lever where a hole for a conventional weaving joint is formed. The wire is in turn provided with a transversely cylindrical end element, preferably made of metal such as, for example, a zinc alloy, which fits with a good fit in the hole of the lever. The holder / locking adapter is also designed with a transverse hole in which the cylindrical cutting element of the wiper passes with minimal gap. The holder / locking adapter is provided with a continuous recess and its transverse bearing is partially open in the direction out from the lever heat, which allows the wire and its transverse cylindrical elements to be mounted and fed down into the holder / locking adapter and into the lever.

When mounting, the holder / locking adapter is first pushed onto the outer end of the lever, after which the transverse cylindrical element of the cable is lowered into the hole located in the holder / locking adapter and also down the hole of the lever. At the same time, make sure that the wire is pushed down into the ice groove end network in the outer part of the holder / locking adapter. Preferably, when the beam is subsequently displaced, at least 90 degrees, 100 degrees, for final assembly so that the shaft of the beam feels fixed to the frame of the vehicle or tool hatch, the beam or its transverse cylindrical element is prevented from sliding out of the holder / locking adapter. The holder / locking adapter automatically fixes / locks the lever to the lever / link system when the lever is rotated and mounted in its operative position. The components self-lock on this set to each other and form a secure connection between the wire and the sea arm.

The unloading according to the invention meant that the locking adapter and the wire automatically lock each other in the desired position without in the form of screws or additional fastening elements, e.g. similar, needs to be used and assembled. This gives a saccharene strap at the same time simple construction which thus allows one-cost-effective assembly. The unloading also provides an almost-mast-free connection at the same time as the holder / locking adapter through the manufacture of a plastic material provides a shock-absorbing effect during the movements of the wire and the sea arm, which reduces the risk of fatigue of the components. The plastic also provided a protection against wear of the metal parts in the construction. The design of the holder / locking adapter also makes it easier and cheaper to implement the solution in the new manufacture of vehicles, but it can also replace the standard cable assembly when repairing already manufactured / existing vehicles. Due to its design, the holder / locking adapter can be used regardless of whether the wire is placed on one or the other side of the holder arm. During assembly, the holder / locking adapter is then only turned upside down so that the wire runs in one of the stud grooves.

Further features and advantages of the invention will become apparent from the following, more detailed description, of the invention, and from the accompanying drawings and other claims.

DESCRIPTION OF PREFERRED EMBODIMENTS The invention relates to a dressing comprising a holder / locking adapter for fixing / retaining a wire in a single wire fastener or in a joint to reduce the play in the joint, fatigue failure in the joint and securing the connection between reducing or eliminating the risk of locking.

Figures 1a-c show a normal and known loosening of a joint between a wire 1 and a sea arm 2 through a hook-shaped and-fastening 3 of metal. Figure 1b shows the joint from the side and Figure 1c shows how a fatigue fracture has occurred in wire sand fastening 3. Due to prolonged wear and impact by hard bumps, the wire fastens with time and the connection to the sea arm ceases.

Figure 2 shows in perspective a part of a tool hatch 4 and its frame 5, and more particularly a locking device 6 for such a hatch 4 arranged in a vehicle such as a heavy truck, showing how the lever arm 2 for opening the hatch 4 is mechanically connected to a wire 1, which runs in a wire housing 7, via the holder / locking adapter 8 according to the invention. The wire 1 leads inwards with which the door 4 in turn to a control handle (not shown) can be opened manually.

Figure 3 shows the invention in more detail in an exploded view the holder / lock adapter 8 and the wire 1 with an outer transverse cylinder in the components included in the joint, the sea arm 2, risk element 9. The holder / lock adapter 8 is proposed in one piece and provided with a horizontal through-going / longitudinal recess 10 intended to accommodate the outer arm end portion 11 and the part of the sea arm 2 where a hole 12 formerly conventional wire connection is received. The wire's transverse cylindrical elements 9 are preferably made of metal such as, for example, a zinc alloy, and can be inserted with good fit and little tolerance in the vertical holes 12 of the sea arm. The holder / locking adapter 8 is also formed with a continuous vertical hole 13 in which the cylindrical part element 9 of the wire fits with minimal play.

The holes 13 of the holder / lock adapter are arranged to be placed / fitted coaxially with the holes 12 of the holder arm 12. The holes 13 of the holder / lock adapter are arranged with an opening 14 facing away from the holder arm 2 which allows the wire 1 and its cylindrical elements 9 to be mounted by the holder / locking adapter 8 is lowered with the wire 1 substantially bent / directed outwards from the sea arm 2, approximately in the direction of its axial extension. The opening 14 is preferably arranged at an angle in relation to the final operative position of the wire 1 where the angle is smallest, but preferably larger than, 90 degrees, preferably about 100 degrees (see Figure 7a, b), in order to prevent the wire 1 and its sub-elements 9 slides out of the holder / lock adapter 8 during use / operation.

The cylindrical hole 13 of the holder / lock adapter is substantially the same size, has substantially the same diameter as the hole 12 of the sea arm and the cylindrical member 9 of the wire has a diameter substantially the same as the hole 13 of the holder / lock adapter 13 and the hole of the sea arm, so that the gap between these components is minimal. The holder / locking adapter 8 is arranged with at least one limiting means 15, which forms at least one support groove 16a, b, which is intended to keep the wire 1 in the desired position and the risk of metallic wear / wear between the wire 1 and the sea arm 8.

Figure 4 shows the same view as Figure 3, but the holder / lock adapter 8 has been mounted on the holder arm 2. In this case, the hole 12 in the holder arm 2 and the hole 13 in the holder / lock adapter 8 are coaxial / centered with each other to enable the wire 1 transverse cylindrical members 9 can be lowered through the holes 12,13.

Figure 5 shows the same view as Figures 3 and 4, but has wire cable elements 9 continued down, placed, through the holder / lock adapter 8 and the sea arm 2 but not yet rotated to its final operative position.

Figure 6 shows the same perspective as Figures 3-5, but the harrow wire 1 has been rotated about 100 degrees from the first mounting step and pushed into a support groove 16a in the side of the holder / lock adapter 8. This stud groove 16a holds the wire 1 in place and reduces the risk of it the metallic groove of the wire 1 against the sea arm 2. Two support grooves 16a, b are preferably arranged in the holder / lock adapter 8 to enable the holder / lock adapter 8 to be watered and used for mounting the wire 1 also from opposite directions.

Figure 7a, b shows in perspective two possible mounts of the holder / locking adapter 8 on the sea arm 2 and how the wire 1 with its wire housing 7 in one case is mounted to the right in the figure and in the other case is mounted on the left, and the holder / the locking adapter 8 can thus be watered depending on the desired mounting. The holder / lock adapter 8 can be fitted with recesses 8 on the top and bottom in order to reduce material consumption and keep down the weight of the holder / lock adapter during manufacture.

The above description is primarily intended to facilitate the understanding of the invention and is of course not limited to the stated embodiments but also other variants of the invention are possible and conceivable within the scope of the inventive concept and the scope of subsequent claims.
