## Abstract

The invention relates to a device for securing floating bodies (1), in particular platforms and boats, comprising at least one floating dock (2) with at least one buoyancy element (3), a path structure (4), and a framework-like underwater structure (5). In order to provide advantageous disembarkation conditions, the path structure (4) and the framework-like underwater structure (5) of the floating dock (2) are connected to each other via pendulum supports (6) and are braced via pulling means (7), in particular cables and/or claims.

## Claims

### Claim 1

A device for securing floating bodies having at least one floating dock having at least one buoyant element, having a path structure, and having a framework-shaped underwater structure, wherein the path structure and the framework-shaped underwater structure of the floating dock are connected to one another via pendulum supports and are braced via a traction device comprising cables and/or chains.

### Claim 2 (depends on 1)

The device according to claim 1, wherein the floating dock is fixed on a landing body using at least two holding trees, which each engage at one end on the floating dock and at the other end on the landing body, wherein the holding trees, which are fixed on mooring points, comprise two subtrees displaceable one inside another telescopically, which are braced against one another by a spring unit which absorbs traction and compression forces acting on the holding tree.

### Claim 3 (depends on 2)

The device according to claim 2, wherein the holding trees engage at one end on the framework-shaped underwater structure, which is optionally widened transversely to a web toward the landing body, and at the other end on the landing body.

### Claim 4 (depends on 1)

The device according to claim 1, wherein the framework-shaped underwater structure has a width which protrudes beyond the path width.

### Claim 5 (depends on 2)

The device according to claim 2, wherein the floating dock and the landing body are secured by crossing traction devices comprising cables and/or chains.

### Claim 6 (depends on 2)

The device according to claim 2, wherein the holding trees are designed as pendulum supports and engage at one end on the floating dock and at the other end on the landing body.

### Claim 7 (depends on 1)

The device according to claim 1, wherein the framework-shaped underwater structure comprises a rib framework having transverse ribs aligned transversely to the dock longitudinal direction and longitudinal ribs connecting the transverse ribs.

### Claim 8 (depends on 7)

The device according to claim 7, wherein the traction device comprises cables and the transverse ribs span a triangle which is connected via the pendulum support and the cables to the path structure.

### Claim 9 (depends on 7)

The device according to claim 7, wherein the traction device comprises cables and the rib framework is secured per se and/or with the path structure using the cables engaging at node points of the rib framework.

### Claim 10 (depends on 1)

The device according to claim 1, wherein at least parts of the framework-shaped underwater structure are designed as the buoyant elements.
