Description

Technical device The present patent application relates to a fixed device for resilient elements in a resilient unit, not included in the anchoring system, in accordance with the claims.

Technical background In a number of situations and contexts, there is a need to anchor objects that float on the surface of a hay, lake or other watercourse to at least a fixed structure or the like below the water surface. Such needs exist, for example, when anchoring floating bridges and corresponding structures. In order to enable anchoring of floating bridges and the like, a number of different types of anchoring systems with input components have been developed.

A problem in anchoring floating bridges and the like to objects, for example covered on the bottom of a hay, a lake or the like, is that the water level, i.e. the level of the water surface in relation to the bottom, varies. The variations are caused, among other things, by tidal variations, variations in wind directions and wind strength, and of course also by waves. In order to enable differences in water level and its effect on the anchoring means, there are several devices which allow a flexibility of the length of the anchoring means. Another problem in these anchoring devices is slack in connecting ropes and the like these can cause bats, bat propellers and the like to get stuck in the slack.

AU using anchoring systems to anchor bridges and the like to foundations on the bottom, anchors and the like on the bottom meant a number of different problems. One of these problems is that existing anchoring systems include details, for example steel, which corrode in connection with prolonged contact with water. Since the kanda anchoring system is usually under water throughout its life, the material in non-volatile components, especially if it is in water with a high salinity, will be exposed to various types of corrosion. Different grades of stainless steel, so-called acid-resistant steel, reduce the incidence of corrosion problems, but these materials corrode over time if placed in seawater with relatively high salinity. The corrosion problems cause details in anchoring systems to corrode to such an extent that they malfunction or completely break down. 1 The corrosion problems in components included in fixed devices and included in anchoring systems can be of different types. The most prominent type of corrosion, in fasteners that include screw joints, is crack corrosion. Crevice corrosion occurs between two adjacent surfaces where water can penetrate and then deplete on oxygen, creating a local corrosion cell. Crevice corrosion thereby occurs between the nut and the bolt in the screw connections of the fasteners. With regard to the occurrence of crevice corrosion in screw joints, there is thus a need for an improved fastening device which, to a lesser extent than previous constructions, comprises screw joints.

One way to reduce the problems of corrosion is to choose a material that corrodes to a lesser extent. A conceivable such material is made of titanium. The problem with changing all materials from steel to titanium is that all titanium had a higher price than steel, which in turn means that all the product becomes relatively more expensive. In order to reduce the material cost, it is therefore of interest to reduce the amount of material in the anchoring device without compromising all the function of the construction.

There are also other problems than material problems with fasteners in anchoring systems which include screw joints. First of all, the screw connections require all a number of work steps to be performed during their assembly. According to kanda procedures, the usual bolt is lubricated in the screw joints with fittings, after which the peck's bolts nuts and then At is tightened with a predetermined tightening torque. The procedure involved unclean conditions for the person performing the work and also meant that the grease contaminated the surrounding water. Secondly, the screw connections can cause work environment problems during repetitive work steps in connection with the tightening torque Transfer to the operator, via, for example, nutrunners, which for a longer period of time entails a risk that the operator suffers from load injuries.

Kind technology Fixing devices for anchoring means included in anchoring systems, for example floating bridges and other floating structures, are already known in several different variants with different construction and shape. For example, the marketing company Seaflex, which is applying for this patent application, has such a construction which is shown schematically in Figure 1. Although this construction much choice fulfills its purposes, it has a number of shortcomings. For example, this is made of steel and includes a number of screw joints. Data carries a risk of corrosion such as crevice corrosion in the screw joints. The construction also entails high material costs if the steel is replaced with titanium. In addition to pure material problems, the construction also has certain other shortcomings. For example, in certain situations unfavorable bending moments occur in parts of the construction. Furthermore, the construction only meant that an even number of rubber cables could be connected to the device in order for a satisfactory function to be obtained.

Patent specification WO95180038 describes a variant of a mooring system for ships which comprises a connecting element, with a trade which is connected to a female part, which is placed in a ship in a suitable position. The construction differs in substantial extent from the construction in accordance with the present patent application.

The connection part is fixed in a control unit which consists of a part which is fixed on several legs. The part is designed so that it has a recess-like portion where the ball is fixed. In a second embodiment, the control unit comprises a base portion which has several recesses where the recess part can be connected. The construction differs in substantial extent from the construction in accordance with the present patent application.

U.S. Pat. No. 4,411,4553 describes an anchoring device for batteries. The construction comprises a tubular part which has recesses in its upper and lower part for fastening a rope or the like when anchoring a bat. A ball can also be attached to the rope, by connecting the ball to the recess of the tubular part. The construction differs in substantial extent from the construction in accordance with the present patent application.
