Description

The invention relates to a fastening hook according to the preamble of claim 1.

110931

Attachment Hook 5 There is a prior art known from U.S. Patent Application 941555, a boat hook comprising a handle and a hook at one end thereof for attaching a boat to a buoy or the like. The hook includes a hook support fixedly secured to the arm, a curved hook member pivotally hinged to the hook support, and locking means for locking and releasing the curved hook member in the hook position. The locking device includes a lock pin and lock recess. The lock pin is adapted to move and rest on the arm and / or when hooked. The locking recess is arranged at the base of the hook portion. The lock pin is inserted into the lock recess when the curved hook portion is locked into the hook support in the hook position. The hook further comprises a closure means for closing the interior of the hook and preventing, for example, the steel loop 15 of the mounting buoy from slipping off the hook.

The disadvantage of the prior art boat hook is that the hook portion is firmly supported on the hook support at the hook feed, which requires a relatively wide mouth opening in the interior of the hook so that the steel loop of the boat buoy can be easily fitted therein. The wide mouth, in turn, reduces the load resistance of the hook or must be reinforced accordingly.

Another disadvantage of said boat hook is that the closing element is not functioning reliably. The closure member is pivotally mounted on the hook support or arm and is only held by the spring in the closing position, i.e., the position where it closes the mouth of the hook into the interior of the hook. In this case, for example, the occasional hard pull of the boat hook attachment loop from the inside of the hook towards the 25 mouth openings may damage the spring, causing the spring member to fail and release the hook.

A disadvantage of a known boat hook is also its limited use. It is mainly suitable for mooring boats to mooring loops on mooring buoys.

It is an object of the invention to eliminate the drawbacks associated with the above boat hook. It is also an object of the invention to provide a new mooring hook which can be used in a wide variety of applications, especially in small boats, for securing them to mooring loops and / or boat buoys. Of course, the hook can also be used for other types of fastening and / or fastening ropes.

In the hook position K, a small resting space 13 is provided between the stop cam 11 and the hook 12 by means of a spring 5 arranged in connection with the hook part fixing shaft or pin 4 and a stop 33 arranged on the front part 2a of the hook body 2. In the hook position K, when no outward force is exerted on the hook member 3, the spring 5 presses the hook member 3 against the stop 33 by a spring force and a resting gap 13 exists. When the free end 3a of the hook part 3 is pressed outwardly from the hook body 2 against the spring force of the spring 5, the resting gap is at least partially closed and the hook part 3 can open or turn out a short distance before the hook 12 meets the opening movement of the bar.

The attachment hook 1 also includes a closure member 21 with a spring 23, the locking strap 26 formed by the hooked body 2 and the hook member 3 is closed by the closure member 21 in its locking position, Fig. 1. Similarly, the threading gap 26 is opened in the release position The closing member 14 35 is pivotally secured to the hook frame 2 5 110931 by a pin 22 or a corresponding axis in the vicinity of the free end 3b of the hooked part 3 locked in the hook position K, preferably opposite it. In addition, the pin 22 of the closing member 21 has a spring 23 arranged to pivot the closing member 21 outwardly from the hook body 2 in the direction L and in its locking position, particularly against the stop 34 of the hook body 2.

A first recess 25 is provided at the first free end 3a of the hook portion 3 and is preferably disposed on the side of the free end 3a of the hook portion opposite the closure member 21 on the other side of the threading gap 26. In this recess 25, the free end 21a of the closure member 21 is disposed in the locking position while the hook portion 3 is locked by locking means from the locking head 3b to the hook position K. The first recess 25 of the en-10 is is pressed in the pushing direction P, i.e. towards the mounting space 32 and the hook part 3, in particular the free end 3a of the hook part, pressed outwardly from the hook body 2, whereby it is resilient and the rest 13 between the stopper 11 and the hook 12 closes.

The lever member of the release member 14 is most preferably provided by the first opening 14a. A first aperture 14a is disposed in the locking member 7. At this point, a second, preferably elongated, aperture 15 is correspondingly disposed at the rear portion 2b of the hook frame 2 through which the second aperture 14a 5 forming the lever means is accessible. When the locking member 7 is in the locking position J, the first opening 14a or the corresponding lever means is at the first end of the second opening 15 and, respectively, when the locking member 7 is in the release position H, the first opening 14a or the corresponding lever means is at the second opposite end of the second opening 15. When the locking member 7 is pressed by a finger or a similar projection from the first opening 14a against the spring force 10 of the spring 10, the locking member 7 moves from position J to position H and the hook member 3 is released from the hook body 2 and .

The locking means further comprises, in the exemplary embodiment shown in the drawings, a rear locking means arranged in connection with the locking member 7 and the hook frame 2 comprising a third aperture 16 and a locking pin 17 in the moon. In this third opening 16, a rear locking pin 17 can be fitted, by means of which the hook frame 2 and the hook part 3 are locked. When the pin 17 is inserted into the opening 16, the locking member 7 cannot be moved, i.e. pressed from the locking position J to the release position 20, because the pin 17 locks the locking member 7 from the opening 16 in relation to the hook frame 2.

Preferably, the locking means 6 also includes a second release member 19. This is implemented by providing a fourth, preferably elongated, opening 19a in the hook body 2, partially fitted in front of the locking member 7 in the locking position J near the first opening 15 of the rear part 2b of the hook body 2. . Connected to the release member 19 is an opening means passing through an opening 19a, such as a closed loop loop 20, which, at a distance, can be pulled into the open position H and the hook member 3 released from the locking hook body 2.

The clamping hook 1 comprises clamping means 27, such as an opening, loop or projection 30 provided on the hook frame 2 for fastening the rope 27a or the like to the clamping hook itself. The fastening hook 1, and in particular its fastening space 32, is connected to a suitable fixed structure or similarly arranged fastening ring 35, and the actual fastening rope 27a or the like is in turn fastened to the fastening hook fastening means 27.

The arm 28 is also connectable to the attachment hook 1. The arm 28 is preferably a telescopic arm. The arm 28 is removably secured to the attachment hook 1 by suitable means 30 as shown in Figures 6A and 6B. Preferably, the engaging means 30 of the arm 28 include a T-projection 30a in the arm attachment portion 29 and a T-groove 30b on the side 2c of the hook body 5 2.

Preferably, a release means 31 is fixedly attached to the attachment portion 29 of the arm 28. This release means 31 allows the first release member 14 to be released by engaging the arm 28 disengaged from the hook 1 to release the locking member 3 from the hook body 2 at its free end is a hook 31b which is specifically engaged to open the first release member 14, which acts as a lever for opening the securing hook.

The hook frame 2 and the hook portion 3 of the attachment hook 1 are made of plastic, preferably GRTVOR ™.

The fastening hook according to the invention operates as follows. For example, when the boat is to be moored to the mooring followed by the mooring loop, the boatman attaches the mooring hook 1 to the arm 28 and reaches the mooring hook 1 towards the mooring loop. The hook frame 2 and the hook portion 3 of the attachment hook are then in the hook position K, as shown, for example, in Figures 1 and 5. The clamping loop is threaded through the threading interval 26 20 into the clamping space 32 as described above. When the dock attachment loop 35 is in the fastening space 32 of the attachment hook 1, the closure member 21 prevents its exit. The mooring hook 1 is secured to the dock, and by means of the mooring hook, the boat mooring rope 27a is secured to the mooring via the mooring hook mooring means 27. Naturally, the boat can be secured with a number of mooring hooks and attached ropes to the side 25.

When the boat is released from the dock, to the first release member 14 of the mooring hook; 14a is actuated by pressing it so that the locking member 7 moves from the locking position J to the unlocking position H as described above. The first release member 14 may be actuated either simply by hand pressing with a finger or by a release means 31 disposed at a distance 30 from the arm 28, as described above. Alternatively, the second release member 19 may also be actuated by pulling the rope link 20 so that the locking member 7 also moves from locking position J to release position H. When released from the hook body and hook position K, the hook member 3 will automatically rotate to FIG. 5, wherein the 1109 ό'ΐ dock anchoring loop 35 in mooring space 32 is released from the mooring hook 1 and, of course, the mooring hook 1 is retractable by the mooring rope 27a to the boat.

To prevent accidental release of the hook 1 from the hook position K to the free position V, it is possible for the locking member body 7 to be locked in place by the locking pin 17 5 and the associated third opening 16. It is only after the locking pin 17 has been removed from the opening 16 that the locking member 7 can move in the cavity 8 in the longitudinal direction A-A and it is possible to open the locking hook.

The invention is not limited solely to the above exemplary embodiment, but many modifications are possible within the scope of the inventive concept as defined in the claims.
