PROTECTIVE ELEMENT (FENDER) OF RUBBER

OR SUCH MATERIAL.

The invention relates to a protective element (fender) of rubber or such a material with a longitudinal recess and fasteners arranged therein.

. 5 Ships and port installations are extensively equipped with fenders of the above type. The fenders must prevent damage that could occur when mooring and maneuvering ships. With increasing size of the ships, additional requirements are also imposed on the fenders, which relate both to the load capacity by large forces and to large spring strokes. For this reason, fenders are already known for large-tonnage ships, which consist of separate rubber blocks and are arranged next to or above each other such that they cover the entire bow and stern section of a ship. The size of the block fenders means that they can only be manufactured separately in molds, so that the necessary tolerances are not exceeded. These tolerances are determined by the fasteners. With such large block fenders it is particularly disadvantageous that the fastening means are correctly fitted only with great difficulty. can be brought.

The object of the invention is to provide large fenders of the type mentioned in the preamble, which allow a considerable simplification in the application of the fasteners and at the same time are easier to manufacture. This must be achieved at least in part because the fasteners can then also fully fulfill their function if the tolerances are subject to only small requirements.

This objective is achieved in that the fender is generally viewed as an ϋ-profile open at the bottom and the two supporting feet comprise grooves lying behind inwardly projecting ribs 8200996 «I ·.

In the first place, such a fender has the advantage that it can be manufactured according to an injection molding method, so that the more expensive manufacture in molds. expires. Furthermore, such a fender can be cut to a suitable length as required, so that a better adaptation to the circumstances is also possible. This creates a very universal application possibility. At the same time, the special design of the supporting feet means that the fixing is considerably simpler, since the fenders are, in simple terms, suspended from the respective fixing means. The fasteners, such as rods or pins, can be better adapted to the respective circumstances. The pins resp. rods are herein inserted into the grooves and at the same time are held in this position by the inwardly projecting ribs. The width of the grooves must be adapted to the fasteners. This leads to a precise fixation of the fender, when these have to be arranged in groups next to and behind each other. The ribs have a thickness and height adapted to the load. It must be ensured here that a sufficient elastic deformation in the area by the fastening means is possible, without the ribs being bent too far sideways. When dimensioning the groove width, the rib pressure and the rib height, it is expedient to start from a Shore hardness around 65 °. Preferably, a rubber type is used which is sufficiently resistant to the loads occurring in seawater.

The surface of the fender is corrugated in the direction of the ribs. This design avoids a large surface pressure and thus guarantees better functional resistance.

The invention is illustrated by way of example in four figures. Figure 1 shows the cross section, Figure 2 is a perspective view of a polybutadienstyrol fender with a Shore A hardness of 70 °. Figures 3 and 4 show the attachment from the side and in section.

As shown in Fig. 1, the fender 1 in the central region of the end face has about a wall thickness of 100 mm.

The fender is U-shaped in cross section and open downwards: 82 0 0 9 9 6 · * ’“ »* - 3 - open. Feet 2 and 3 rest on the side of the ship and merge into ribs 4, 5. Behind it lie grooves 6, 7 in which round bars 8 and 9 are arranged. This is shown in fig.

3. By means of these round bars, which extend around the bow of the ship, the fender can be held firmly in its position. At the same time, groups of fenders can be present, as shown in Figure 3. The width of the feet 2 and 3 is in each case approximately 100 mm. Ribs 4 and 5 are approximately the same height. The distance between the ribs is approximately equal to half the width of the feet. The distance is sufficient if the round bars 8 and 9 can be pierced without further ado. The grooves 6 and 7 are adapted to the thickness of the round bars 7 and 8. Figure 2 also shows that the fender is provided with ribs on the surface:. * 8200996
