Il 76974 DEVICE TO FACILITATE THE ATTACHMENT AND REMOVAL OF BOATS, ESPECIALLY IN THE CONTEXT OF BUOYS

The invention relates to a device for facilitating the mooring and uncoupling of boats, in particular in connection with buoys, which device is intended to be connected to the end of mooring ropes and comprises a rod at the first end of which a hook is fixedly locked by a removable latch which can be guided by a rod. at a second end away from the hook by means of a rod, said rod being rotatable relative to the rod and provided with a handle which can be handled at said first end of the rod to facilitate this rotation.

Mooring a boat, especially a high-rise boat, to a buoy often causes considerable difficulty, not least if a single person has to take care of mooring and steering the boat at sea at the same time. Even detaching from a buoy is difficult in such circumstances.

U.S. Pat. No. 2,983,243 discloses a device of the quality mentioned at the beginning. However, the known device has several shortcomings which make its use difficult, unnecessarily complicated to manufacture and reduce its reliability.

It is therefore an object of the invention to provide an improved fastening aid of the quality mentioned in the guide, which allows the hook to be struck even when the latch member is in its operative position, has a solid structure without sensitive and corrosive details and eliminates the need for special locking measures. in its inactive position.

In this respect, the device according to the invention primarily has the features of claim 1 2 76974 below. Other features of particularly preferred embodiments of the subject matter of the invention appear from the subclaims.

In order to clarify the invention, an embodiment of the device is shown in the accompanying drawing, in the framework of which, however, several detailed modifications are possible without abandoning the inventive idea of a fundamental quality according to the claims.

The drawing shows: Figure 1 a side view of the device with the hook latch member in the operative position;

Figure 2 is a view of the same device from the side against which the tip of the hook is turned;

Fig. 3 is a view of the device from the opposite side to Fig. 15 with the hook latch member in the inactive position;

Fig. 4 shows on an enlarged scale a cross-section of Fig. 1 along either of the lines VI-VI, and Fig. 5 likewise shows on an enlarged scale a cross-section of Fig. 1 along the line V-V.

It should be noted that the drawing shows, for the sake of clarity, a form of the subject matter of the invention which is exceptionally short in relation to other dimensions.

In the drawing, the fastening means generally indicated by reference 10 comprises primarily a support hook 11 fixedly fixed, e.g. welded, to one end of a tubular rod 12, at the other end of which a fastening ring 13 is fixedly fixed for the fastening rope 14, thus the fastening means 10 . Rope 14 can be

The hook 11 is attached along the other edge of the flared end portion 15 of the tubular rod 12, the rod having an oblique end surface 16 and forming a hollow hook neck with crude inner cross-sections (Fig. 4), the longitudinal direction of which coincides with the plane of the hook. The opposite end portion 17 of the rod is correspondingly flattened, so that it has a slit-like cross-section in the plane of the hook 10 between these end portions of the cross-section of the rod 12 and is thus substantially circular along most of its length. For example, the retaining ring 13 is secured by welding to the second flat side 15 of the end portion 17 in a slightly oblique position so that the outer portion of the ring is approximately parallel to the longitudinal axis of the rod 12, and the rod terminates a short distance seen from the flattened side.

A rod 19 of circular cross-section of rigid resilient material, for example steel, is passed through the tubular rod 12, the second end part 20 of which extends up to the hook 11 and forms a latch member for the hook putty 21. The second end portion 22 of the rod 19 extends beyond the opposite end of the rod 25 12 to the outside of the retaining ring 13 and is bent outwardly at an approximately right angle to form a pivot rib. The crosspiece 23 attached to the retaining ring 13 by welding or otherwise prevents the rod 19 from being pulled out of the put-rod rod 12, while the pivot rib 22 in contact with the rod end surface 18 prevents the rod from moving in the direction of the hook 11. In contrast, the rod 19 is pivotable relative to the surrounding rod 12.

The rod 19 is pre-bent or curved at approximately the center of its length, at reference 2U, so that the portions of the rod passing through the flattened end portions 15 and 17 of the tubular rod 12, respectively, form an obtuse angle with respect to each other. Further, the diameter of the rod 19 is thus selected with respect to the width of the slotted inner cross-section in these rod end portions (or vice versa) so that the obtuse angle between the aforementioned portions of the rod must be at least partially corrected so that the rod is rotatable with respect to the surrounding rod 12. This adjustment takes place against the elasticity of the rod, as a result of which the rod retrieves from two pivot positions towards either, namely the first position where the rod end portion 20 is in the hook friction 21 locking position and the pivot rib 22 points in the direction of the hook tip 25 (Figure 1). a position in which the end portion 20 of the rod is placed in the hook-free, inactive position and the pivot rib 22 points in the opposite direction (Fig. 3). Thus, in its inactive position, the end portion of the rod is at the side opposite the hook hook of the hook.

This effect does not necessarily require that the tubular tan-20 ko 12 be flattened in the region of the end part 17 connected to the fastening ring 13, but said effect is already enhanced in this way.

Of course, when the end portion 20 of the rod 19 is in its operative position (Figure 1), it prevents the hook 11 from striking out of itself. On the other hand, it does not prevent the hook from striking, since in this case the end part 20 of the rod acting as a locking member is quite easy to move away from the hook crystal 21 when the rod 19 is springed, as indicated by the arrow. Thus, in the fastening, the rod 19 should be in the position shown in Fig. 1, while in the removal it should be moved to the position shown in Fig. 3, so that the hook 21 remains completely free. The movement of the rod takes place, of course, by a pivoting bar 22, which at the same time indicates the position of the rod, and requires only so much force that the risk of unintentional action is practically non-existent.

Claims (3)

To facilitate the manufacture of the device and the possible replacement of the flexible rod 19, the cross-section 23, as shown in Figures 1 and 2, is bracketed and welded to the fastening ring 13 at its short bracket ends in such a position that free space remains in the slotted end opening of the rod 12. At the same time, the pivot rib 23 of the rod 19 has a dimension so dimensioned that it can move past the brace-like cross-section if it is forced against the elasticity of the rod as far as possible to the left in Figures 1 and 3. Thus, the rod 19 can be placed in the rod 12 and pulled out. with a certain effort to ensure its inadvertent sliding out. As can be seen from Figures 1 and 3, the tip 25 of the hook 11 in the example shown is pulled out a considerable distance outside the area of the hook crystal 21 in which the latch 20 operates and at an angle of about 45 ° to the rod 12. Such a design of the hook tip may in certain cases facilitate, but is not required to, engage the hook, for example in a buoy loop. Practical experiments have shown that the length of the rod 12 can suitably be 70 ... 170 cm and that its outer diameter between the flattened end parts can suitably be 15 ... 30 mm. The diameter of the rod 19 may suitably be U ... 8 mm and it must be pre-bent so strongly before being introduced into the tubular rod that it always remains under tension. 6 76974 A device for facilitating the mooring and uncoupling of boats, in particular in the case of buoys, which device is intended to be connected to the end 5 of a mooring rope (14) and comprises a rod (12) at the first end of which a hook (11) is permanently fitted with a removable latch (20). ) which can be guided at one end of the rod remote from the hook by means of a rod (19), this rod being able to rotate relative to the rod 10 and provided with a handle (22) handled at said other end of the rod to facilitate this rotation, characterized in that the latch member (20) is adjustable relative to the rod (12) by rotating between two predetermined positions, namely the first active position (Fig. 1), where it prevents the hook (11) from detaching, but can also turn sideways against the spring action towards the inside of the hook. and between the second, ineffective position (Fig. 3) in which it leaves the kou when the jaw (21) is free and tightly adjacent to the inside of the hook against the hook of the hook 20, the rod (12) is tubular and surrounds the rod (19) connected to the latch member (20) such that the rod sets the latch member to an effective inactive position; and on the contrary, and that this adjustment of the latch member (20) can be accomplished only by overcoming the spring force which tends to hold the latch member in the particular position in which it is at that moment.
