Description

DK 177426 B1 i

Field of the Invention The present invention relates to a hook system comprising a hook and a locking means, the hook having an orifice for passage of an object in and out of the hook, the locking means being pivotally mounted across the orifice, wherein the locking means has a free end where the locking means is pivotable between a closed position with the free end abutting against the tip of the hook, so that the mouth is locked for the object's passage out of the hook, and an open position with the free end free of the tip of the hook so that the object can pass in and out of the hook through the mouth, where the locking means is spring-loaded in a locking direction towards the closed position and where the hook is pivotally mounted to a housing by a hook shaft.

15

The present invention further relates to the use of a hook system. BACKGROUND OF THE INVENTION Hook systems are used in many different contexts. For example, in the case of cranes where the hook systems form a connection between a load and a lifting wire or in connection with mountaineering, where hook systems are used to secure the mountaineer by establishing a connection between the mountaineer's harness and wedges attached to the support 25

Another use of hook systems is in connection with shipping, where hook systems are especially used in connection with the port of a harbor, where for example boat hangers with hook systems are used to catch moorings on land and bring them within reach of the crew, so that the ship 30 can be safely moored. .

DK 177426 B1 2 Common to all the hook systems mentioned is the requirement for reliable operation and protection against accidental release. To prevent accidental release, the hook systems are provided with a locking device which allows an object, for example a mooring line, to pass into the hook system, but the object then cannot pass out of the hook system without the device being previously opened by a user. .

In case of lifting hooks, it may be satisfactory that the locking device can be operated close to the hook system, since the user will be close to the hook system when it is to be released from the load.

In other contexts, the locking device may need to be operated remotely so that the user does not have to be close to the hook system. An example of such a relationship is a boat chin as discussed above, otherwise the user has to reach beyond the rail on the ship to release the hook system with the resulting danger of falling overboard.

A hook system of the type mentioned initially is known from WO 01/30647 A1 (RAHIKKA), which discloses a fastening hook rotatably mounted to a hook body and with locking means which lock the hook to the hook body and where the hook and hook body are combined constitutes the attachment hook. The fastening hook is spring-loaded against the closed / locked position. The fastening hook further comprises a locking portion provided with a spring for locking the opening into the hole of the hook. The hook body to which the swivel fastening hook is secured comprises a releasable spring-actuated locking mechanism by which the fastening hook can be released for backward rotation, away from the mouth of the hook and the locking member, by pulling a rope attached to the hook body with a force exceeding the spring action. the closed locked position, after which the object is released from the attachment hook, which then swings back to the starting position, in the closed position. The releasable spring-actuated locking mechanism is actuated by displacing the locking mechanism rearwardly in the direction away from the attachment hook, for example by pulling in a line attached to the housing.

DK 177426 B1 3

The disadvantage of this known hook system is that a separate operation must be performed to displace the releasable spring actuated locking mechanism, for example by pulling in a line while releasing the fastening hook, which makes the use of the hook system slow, which is inconvenient, for example in situ. 5 tions where a breather line should be released at the right moment.

In order to hook the hook, a mooring must be attached to the hook, as well as a temporary boat hook / telescopic rod (via a slot on the hook and telescopic rod), which can be reached according to the item to be hooked. When the workpiece is hooked, hold the mooring and pull the telescopic pole off the hook / slot. When the hook is to be cut off, the telescopic pole is rotated 160 degrees where there is a boat hook (the opposite slot). The chin is inserted into a hole in the rear end of the spring-actuated locking mechanism, after which the locking mechanism is pulled backwards with the chin, or alternatively is pulled backwards by a pull in a separate line, attached to the spring-actuated locking mechanism (see above), whereby the fastening hook is unlocked, simultaneously in the mooring with a force exceeding the spring action of the hook against the closed, locked position, and the hook is free and must be aboard the boat again to be ready for the next chopping.

20

The latter preparation operation also makes it difficult to use the known hook system.

OBJECT OF THE INVENTION It is the object of the invention to provide a hook system that can be remotely operated which provides a secure and reliable closure and which does not require the use of pull lines or hooks to release the hook system from an object.

Description of the Invention 30

This is achieved in accordance with the present invention with a hook system of the type initially described, characterized in that the hook comprises a shaft connected to the hook shaft, the shaft having an extension extending from the hook shaft away from the shaft, which extension cooperates with a contact surface of the housing, the hook being pivotable about the hook shaft between a locking position where the extension is in contact with the contact surface of the housing, and a release position where the hook is turned towards the mouth and the hook comprises a spring member , which is arranged so that the hook is spring-loaded against the locking position, wherein the housing is formed with a locking stop with a contact surface for the locking means, so that the locking means leans against the locking stop while swinging the hook towards the release position for opening the mouth.

The result is that the hook system can be operated remotely, by manipulating the housing with the object in contact with the tip of the hook, the hook can be pivoted relative to the housing and the locking member, as this causes abutment to the locking stop, thus creating a passage for the object between the hook and the tip and the free end of the locking means. Since the hook is spring-loaded, it swings back to the lock position and 15 is then ready for repeated use. The invention provides a secure and reliable closure, with the spring-loaded hook returning to the locking position upon impact. Further, it is accomplished that no separate operations need to be carried out by pulling in rods, hooks or ropes to release the hook from the locked position to the open position, this being done by manipulating the hook housing, typically through a shaft, as will be the case. appear later. This makes the hook system according to the invention very flexible and easier and faster to use than the known hook system, since the hook system is ready to receive a new object in the hook immediately after release from an object, whereas the hook system according to the prior art must first be prepared for it, by checking of trigger line etc. 25

By forming the hook system according to the invention such that the housing is formed with a first hook stop for the hook in the locking position, it is achieved that the object can be brought into the hook by using the housing as a handle, the hook not bending backwards. The hook is thus very stable in the locked position.

30

The first hook stop may be established on the housing as an abutment surface forming abutment for part of the hook so that the hook is prevented from continuing rotation.

DK 177426 B1 5

Alternatively, the first hook stop may be established as a limitation of spring means migration.

According to a further embodiment, the hook system according to the invention may be characterized in that the housing is formed with a second hook stop for the hook in the release position.

Hereby, the object can be released in a more reliable way, the hook being added to a force which ensures a sufficient opening of the mouth.

10

The second hook stop may be established on the housing as an abutment surface forming abutment for part of the hook so that the hook is prevented from continuing rotation.

Alternatively, the second hook stop may be established as a restriction on spring travel of the spring member.

According to a further embodiment of the hook system according to the invention, the housing of the hook system may further comprise a detachable fastened rod, the housing and the rod respectively comprising cooperative means for attaching the housing to the rod.

Hereby the range of the hook system is increased.

The length of the rod is adjusted to the desired range.

25

According to a further embodiment of the hook system according to the invention, the rod can be constituted by a telescopic rod.

The telescopic rod may be so adjustable that it may be set to a first position where the respective telescopic links may be displaced relative to one another, which may be an advantage if the hook system is used as a mooring where tide compensation will be possible. and in another locked position, where the respective joints cannot be displaced relatively and where the respective joints constitute a rod, the length of which can be adjusted according to conditions, which is advantageous when attaching to an object, or triggering the hook system from an object.

The invention solves a further problem in the prior art. Since the prior art, as described in WO 01/30647 A1 uses an operating connection between the trigger on the hook and the user, the length of the rod can only be varied within this range. Furthermore, there is a risk that operating combustion, which is a wire or cord, may entangle and prevent tripping.

This is avoided with the hook system according to the invention, since the hook can be released only by manipulating the rod.

In telescopic rod embodiments, the hook system can be used with the telescopic rod of any length. Provided the telescopic rod can be locked.

15

This achieves that the range of the hook system is increased without the need for storage of the hook system being made space-consuming.

The telescopic rod can be designed with one, two, three, four or more telescopic steps.

20

According to a further embodiment, the hook system according to the invention is characterized in that the hook system comprises a line which is connected to the hook.

Hereby it is obtained that hook system can be used as mooring. The hook system is connected to a mooring object while the line is connected to the vessel. The locking means ensures inadvertent release of the hook system from the mooring object.

The line may be directly connected to the hook or be indirectly connected to the hook via the housing.

DK 177426 B1 7

According to a further embodiment, the hook system according to the invention is characterized in that the hook system comprises locking means for locking the hook in the locking position.

5 By locking is meant that pivoting of the hook towards the release position is not possible or in other words that the hook is locked against pivoting relative to the housing. __

Hereby is added additional security against accidental release of the hook from the mooring object.

Furthermore, the locking means can be combined with a lock so that the user has to use a key or, for example, a number combination to unlock the locking means. Hereby, the hook system can be used as a mooring with security so that the hook system or vessel is not stolen.

According to a further embodiment, the hook system according to the invention is characterized in that the locking means are a pivotable bracket. .

The hook may be formed with an extension abutting the housing. The bracket is swung over the extension to engage the hook so that the hook is locked. The housing can be provided with an opening for a padlock immediately behind the hanger so that it can be closed more securely.

According to a further embodiment, the hook system according to the invention is characterized in that the locking means are a slidable collar.

The hook may be formed with an extension which abuts the housing. The collar is displaced over the extension to engage the hook so that the hook is locked. The housing can be provided with a through opening which also passes through the collar, so that the hook system can be provided with a padlock.

DK 177426 B1 p

The hook system can advantageously be used for a boat chin for mooring / unloading a vessel.

Furthermore, the hook system can advantageously be used in connection with the attachment of fishing gear. When hooking fishing gear such as fishing nets, grab a rope at the edge of the fishing net, an eye in the fishing net or a buoy connected to the net. Here, the hook system can be used advantageously, by securing a secure attachment to the fishing net. The yarn can then be retrieved either by using the hook system directly or by attaching a crane to the yarn. The hook system can easily be detached from the yarn or yarn bag when it is tipped onto the deck of the ship or possibly even before the fishing net is tipped on board.

Other alternative uses of the hook system could, for example, be in mountaineering equipment where the hook can be released with one hand.

Detailed description of the invention

FIG. 1a and b show a side view, respectively, of a first and a second embodiment of a hook system 1. The hook system 1 can be used as a boat hook 20 100 ', 100 "in the embodiment shown.

The boat hook 100 'is formed with a hook system 1 comprising a rod 110 which acts as a handle and which extends the reach of the user.

The boat hook 100 "in the second embodiment is also designed with a hook system comprising a rod 110. This rod is a telescopic rod which further extends the range of the user, but the rod 110 is shorter in the folded state than in the knocked out state.

The boat hook 100 ', 100 "may be provided with a line 120 which can be used for mooring, so that the boat hook 100', 100" may advantageously be used as part of a vessel's mooring where the hook system 1 is connected to an object 2 , for example, an inhalation line, a bollard, a buoy or another mooring object and the line 120 is attached to the vessel. Therefore, since the hook system 1 is releasable, it is easy to unmoor without dangerous situations occurring where a crew member leans over the rail on the vessel to release the mooring.

5

FIG. 2-8 show sectional views of a hook system 1 in a first embodiment. The figures show different situations during the operation of the hook system 1.

In the following, turning directions will be referred to as being clockwise or counterclockwise. This is to be understood from the orientation of the hook system 1 relative to FIG.

2-8. Those skilled in the art will readily be able to translate the designations relative to the orientation of the collar system.

The hook system 1 comprises a hook 3, a locking means 4 and a housing 5.

15

The hook 3 is J-shaped with a shaft 6, an arc 7 and a tip 8. An orifice 9 is defined between the shaft 6 and the tip 8. The orifice 9 is arranged for an object 2 to pass in and out of the hook 3 laterally direction.

The locking member 4 is a pallet mounted transversely of the mouth 9. One end of the locking member 4 is mounted to the end of the shaft 6 of the hook so that it can pivot between two outer positions. The other end, which is a free end 10, is shown abutting the Inner side of the hook tip 8. The locking means 4 can pivot into the hook 3 so that the mouth 9 is open and back against abutment 25 with the tip 8, so that the orifice 9 is blocked. The locking member 4 is spring-actuated in a counter-clockwise locking direction 11.

The locking means 4 may alternatively be mounted to the housing 5.

When an object 2 presses against the locking member 4 from a position outside the hook 3 with a force which overcomes the spring force of the locking member, the locking member swings into the hook to an open position. Since the free end 10 of the locking member is free of the tip 8 of the hook, a passage is formed between the free end 10 of the locking member and the tip 8 of the hook, through which the object 2 can pass into the hook 3. Subsequently, the object 2 passes past the free end 10 of the locking means. after which the locking means 4, under the influence of the spring force, swings in the locking direction 11 for abutment towards the tip of the hook Θ and a closed position. The mouth 9 is now locked so that the object 2 is prevented from passing out of the hook 3.

The locking member 4 in the illustrated embodiment is formed by a pivot spring (see in particular Fig. 9), so that the locking member 4 itself is provided with a spring force in the locking swing direction 11 when pivoted in a clockwise direction. Alternatively, the locking means 4 may be formed with a separate spring arrangement.

The housing 5 comprises a hook shaft 12. The hook 3 is attached to the hook shaft 12 and is pivotable about the hook shaft 12. The hook 3 can pivot between a locking position where the locking member 4 can engage the tip 8 of the hook and in a counterclockwise direction to a release position. The housing 5 is provided with a locking stop 13 having a contact surface 14 for the locking means 4.

As the hook 3 is pivoted in a counterclockwise direction from the locking position to the release position, the locking member 4 abuts against the abutment surface 14 on the locking stop, whereby the locking member 3 is prevented from turning with the hook 3. This opens the mouth 9 by forming a passage between the hook tip 8 and the free end 10 of the locking member 4 so that the object 2 can be released from the hook system 1 in the release position.

In the illustrated embodiment of the hook system 1, the hook 3 is comprised of a spring member 15 which is arranged so that the hook 3 is guided to the locking position. The spring member 15 comprises a spring 16 which is a compression spring and which is clamped between a displaceable spring contact surface 17 on a displaceable rod 18 and a fixed spring contact surface 19 arranged in the housing 5.

30

The hook 3 is formed with a first hook stop 20 for the hook 3 in the locking position. The first hook stop 20 restricts the swing of the hook clockwise so that the hook 3 is stopped in the correct position for the locking position. The first hook stop 20 is formed on

ll-MAY-2012 23 = 39 FROM HAMMELSUANG CONSULT TO 43508001 S.14 / 2Q / U

The housing 5 at an anise face 21 cooperates with an extension 22 of the hook shaft 6.

The hook 3 is further formed with another hook stop 23 for the hook in the release position. The second hook stop 23 restricts the swing of the hook counterclockwise so that the hook 3 is stopped in the correct position for the release position. The second hook stop 23 is integrated into the spring member 15 as a maximum clamping of the spring 16.

The hook system 1 in the illustrated embodiment is provided with a rod 110 which is connected to the housing S. A line 120 is drawn through the rod 110. The line 120 is connected to the hook 3 via the housing 5, which is provided with a split 130 which is wrapped with a loop 140 on the line 120. The line 120 can be used to moor a vessel.

15 In FIG. 2, the hook system 1 is shown with an empty hook 3, the object 2 being ready to be inserted through the opening 9 of the hook.

In FIG. 3, the object 2 abuts against the locking means 4 which is pivoted towards its open position. A passage is formed between the tip 8 of the hook and the free end of the locking member. Object 2 is passing through mouth 9 through this passage .........

In FIG. 4, the object 2 is passed through the mouth into the hook 3. The locking means 4 is, under the influence of a spring force, swung back to the closed position which prevents the object 2 from passing out through the mouth 9.

On tig. 5, the object 2 abuts the tip of the hook 8. The object 2 affects the hook 3 with a force which causes the hook 3 to swing towards the release position. This is done by the user manipulating the housing 5, possibly via the shaft 110, so that the force is built up. The force must be large enough to overcome the spring force of the spring member. The locking member 4 abuts against the locking stop 13 so that it does not swing with the hook 3. This creates a passage between the tip 8 of the hook and the free end 10 of the locking member, so that the object 2 can pass out through the mouth 9.

This is seen in Fig. 6, where the object 2 passes out through the mouth 9. The hook 5 3 then swings back to the locking position under the influence of the spring means 15 and is ready to receive an object 2 again.

The hook system 1 can be used in applications where a user, by manipulating the housing, either directly or via a rod 110 (see Figures 1a-b) connected to the housing, can build up a force which is counteracted by the object 2, thus that the hook 3 opens

For example, such applications may be used in connection with mooring / unloading of a vessel, use of a mountaineer / climber to grip pegs, the hook being released with one hand.

FIG. 7 and 8 show a sectional view of the hook system of FIG. 2 with locking means 24 for locking the hook 3 in the locking position.

The locking means 24 comprise a slidable collar 25 which cooperates with the extension 22 of the hook shaft 6. The collar 25 may be displaced along the rod 110 or alternatively the housing 5.

In FIG. 7, the hook system is shown in the unlocked position where the collar 25 is displaced to a position 25 free of the extension 22.1 in this position the hook 3 can be tilted and released.

In FIG. 8, the hook system is shown in the locked position where the collar 25 is displaced so that it engages the extension 22.1 in this position, the hook 3 in 30 is prevented from tilting, the hook cannot be released.

The extension 22 is formed with a recess 28. The collar 25 is comprised of a locking spring 29. The collar 25 is displaced further towards the hook 3 than the collar 15.
