Description

BOAT HOOK WITH MOTORIZED GUIDE ROLL

The invention relates to a boat hook with a hand-held rod for receiving a attached to a harbor wall or buoy with one end pilot line, which is connected to the other end with a document line, which is connected to a Muring chain in the harbor or at the bottom of a watercraft and is intended for evidence on a watercraft.

A mooring, or mooring, is a chain anchored to the bottom of the harbor basin or mooring in a body of water. Attached to the chain at the end of a document line to which in turn a pilot line is attached in extension ^¬ tion, which is attached to land, so at the harbor wall or a buoy, in such a way that it is visible with a section, to be able to pick them up in order to be able to ^anchor a watercraft, for example a sailing boat or a yacht, in a harbor, a marina, a mooring or a pier. For this purpose, on the one hand, the vessel is fastened to a bollard or a buoy with a rope (also called a rope) and, on the other hand, the document line is fixed at the other end of the vessel. For this purpose, the pilot ^¬ leash is taken by a boat hook by a member of the crew and pulled by hand on the vessel or placed in a winch, which at the same time the document line is pulled out of the water and in ^¬ example on the forecastle, z. As a cleat, can be attached. This type of mooring of a water ^¬ vehicle has particular advantages in recreational craft, which usually moor backwards, so with the rear, at the dock or at the mole. The ejection of an anchor is thereby superfluous and a secure mooring of Was ^¬ serfahrzeugs is guaranteed. It can be seen that it is not done with the pickup of the pilot line by means of the boat hook, but the pilot line and the document leash must be picked up by hand. Even if gloves are ge ^¬ wear, soiling of clothing and the person who receives the linen, unavoidable.

From DE 200 12 335 Ul a boat hook with a pulley is known, which is rotatably mounted on a rod. The role is provided on the surface with a bowl ^¬ shaped storage ring for the rope. So that the rope can not slip out, a cable slip protection made of metal or plastic is provided. Similar boat hooks are also known from FR 2 657 837 A1, from FR 2 682 075 A1 and from EP 0 460 473 A1.

Starting from the prior art, the invention is based on the object to execute a boat hook so that the pilot line and possibly the associated

Lanyard easily taken and can be brought without special force ^¬ expenditure of the operator in such a length position to attach the watercraft with the Be ^¬ legleine tightly fastened to a cleat or a hook on the forecastle can.

The object is achieved by the specified in claim 1 embodiment of the boat hook. The boat hook according to the invention is characterized in that it has as a pickup for the pilot line and / or the document line a substantially V-shaped, rotatably mounted on a protruding axis on the rod roller, which is driven by a motor drive, in or mounted on the hand-held rod and controlled by a control on the rod, the roller rotates at least in one direction of rotation optionally. The Hook shape is thus given by the V-shaped configuration of the role.

The role may also be formed of two profile parts, which are formed for example of stainless steel sheet and are frusto-conical. These two parts are welded together in the middle or screwed together and fixed to the motor shaft. For this purpose, a hub may be additionally provided. As far as is spoken of a substantially V-shaped training, this may also be concave or convex curved flank surfaces, which are always to be designed so that the pilot or document leashes are fixed therein in a defined altitude when they are from the Roll of the boat hook are under attack.

The person picking up the pilot line can grab the pilot line with the V-shaped roller on the pole. If it presses on the control means at the same time, for example, a toggle or key switch, the motor is supplied with power and causes a rotation of the roller in the desired direction, so that the Pilotleine at the same ^¬ time impressions in the V-shaped mounting taken and pulled out of the water by motor, without the person has to touch the leash itself.

The advantages are obvious. The person does not need to pull the included pilot line on the vessel or does not have to bend over the railing to run the pilot line by the hands while tightening. The pilot line is therefore automatically picked up and tightened until the roll captures the document line. Now the boat hook can be obtained and the lead rope attached to a cleat on the foredeck. It is also possible to supply both a part of the pilot line and the document line to a winch provided as a mooring winch is.

Advantageous embodiments of the boat hook according to the invention are described in the dependent subclaims

Detail given.

According to an advantageous embodiment, for easier insertion of the document or pilot line in extension of at least the edge surface of the roller, which faces the rod, provided on the top side a guide element on the rod or the holder of the motor. In the guide element, it may be z. B. act around an iron bar, which is obliquely welded to the rod and ends immedi ^¬ applicable above the roll edge on the flank surface, so that the pilot line can not fall behind the role and always come in the V-shaped ring of the role can. But it may also be a surface element, ^¬ example, a stainless steel sheet can be provided which is wider executed and angled such that it's the intermediate space bridged between the top edge of roller and the rod. Such a surface element may be fastened on top of a U-shaped support which surrounds the roller on the underside and on the outside of the roller also has on its upper side a guide element extending in extension with the outside flank surface. As a result, an easier recording of the pilot ^¬ or slip line is given. Instead of a surface element here but also z. B. a U-shaped bracket attached to the carrier.

In principle, a hydraulic, an electric or even a pneumatic motor can be used. In the case of a hydraulic or pneumatic motor, a connecting line must be available in the boat and further a supply line for the medium must be provided between the hook and the connection; Similarly, if an electric motor with power supply via a cable is provided.

However, a boat hook according to the invention can be configured more simply if the motor is an electric motor with accumulator power supply. This may be, for example, a 12-volt DC geared motor whose number of revolutions is controllable. The motor can be mounted flanged on the bottom of the bar. For this purpose, for example, the housing of the motor can be provided with a receptacle for the rod. The housing of the motor has a penetration in the shaft. In this example, a screw can be screwed, via which the roller is flanged to the engine. It goes without saying that the gear motor must be waterproof.

In order to record both left and right side of a pilot line on the vessel, it is advantageous to provide a direction switch on the rod to the motor can specify by turning a direction of rotation can, which ensures that the pilot line transported through the Rol ^¬ le becomes. The clear width of the V-förmi ^¬ gen roll may be the upper side between about 70 mm and about 80 mm, the bottom side 10 mm to about 40 mm, so that the pilot lines in sizes of about 25 mm to about 50 mm transit always be recorded and transported. The diameter of the V-shaped roll may be, for example, about 150 mm to about 180 mm. For lines up to 50 mm in diameter, the inner surfaces of the roller may be toothed or rough coated or roughened or have grooves to move the line in the desired direction.

The use of a DC motor also has the advantage that the required current can be supplied by an accumulator which is either inserted into the rod itself or implemented in an attached housing, for example in an upper handle housing. This Housing should be designed to be removable, so one

Recharging the batteries in a power supply unit is made possible, or it should be a charging socket before ^¬ seen, in which a charging plug of a power supply is inserted. Furthermore, the control should be designed so that the speed of the motor can be controlled. It is thus possible to control the motor between one revolution per minute and for example 500 revolutions per minute. The control is advantageously designed as a pressure switch, so that the speed is increased by increased pressure or by prolonged pressure. If two such pressure switches are provided at a distance from each other on the rod, the left and right rotation can be controlled accordingly. The pressure switches are also on or in the pole.

If the rod is a hollow rod, the motor can also be installed in this. For example, then small motors, as used in automatic shutters in the shaft, can also be used here. These motors can have a drive worm, which acts, for example with a pinion of a gear together ^¬, which is arranged on the shaft of the roller.

The use of a hollow rod also allows to use the batteries in the bar itself. In this case, the interchangeability should be ensured by a closable opening in the hollow rod. Furthermore, a charging socket should be provided, through which the batteries are charged after use by inserting a charging plug, which is part of a power supply unit. This ensures that the boat hook is always kept functioning.

In a further embodiment it is provided that a hold-down is arranged on the rod. This is a a step-sliding slider, at the lower end of which a roller is mounted, which can be pushed onto the line after picking up, so that the line is pressed into the V-shaped opening of the roller. This has the advantage that even if not rough

Surface of the flank surface is given, for example, the Flan ^¬ kenflächen are smooth, a run through the role is ensured at the same time taking along the line. The hold-down with the pressure roller can also be designed so that a small electric motor causes a displacement as soon as the pilot line is received. The movement can also be controlled via a push-button. This can also be done automatically by a sensor on the roller, which determines that a pilot ^¬ line is inserted, and causes the holddown is lowered until a certain pressure force is detected and the power is cut off. A trigger button can be used to retract the electrically operated hold-down device at any time.

In order to adapt the rod to the needs of the watercraft and the person, it is recommended that they form a telescopic pole, wherein the rod of profile tubes, which are inserted into one another, be ^¬ stands, with a complete withdrawal is avoided by securing elements. In this way, the rod can be produced in any desired length in a simple manner. For mutual security, for example, spring-loaded locking hooks can be provided on one part, which engage in the other part. The pole should not exceed a length of approx. 130 cm to 190 cm. The rod can be made of different materials, this applies to both a solid rod and a hollow ^¬ rod. Preferably, such rods consist of aluminum minium, wood, stainless steel, glass fiber reinforced plastic or carbon fiber reinforced plastic. Both of aluminum and plastic, the rods are very light, so that the additional weight by engine, Rol ^¬ le and z. B. accumulators leads to no handling Schwierie ^¬ skills.

The invention will be explained with reference to the additional he ^¬ shown in the drawing ^¬ voltages embodiments.

In the figures show:

Fig. 1 shows a detail of a harbor with a

dangling watercraft,

Fig. 2 shows a first embodiment of a dung OF INVENTION ^¬ designed according boat hook,

Fig. 3 shows another embodiment in the schematic ^¬ partial section and

Fig. 4 shows a further embodiment with Ver ^¬ extension to the flank surfaces of the roll provided on the top guide elements.

In Fig. 1 shows a schematic representation of part of a harbor basin. This harbor basin consists of a harbor wall 2 and a floor 16; this floor 16 may be a concrete floor or sandy floor. The harbor basin is only partially shown and filled with water 5. At the bottom 16 is an anchor 7, z. B. a concrete anchor. At the anchor 7 a Muringkette 6 is attached. At the Muringkette 6 a document line 4 is attached, which is pulled out in the embodiment of the water 5 with a section and attached to the front of the vessel 8. The pilot line 3 is in extension provided and secured with its other end to a ring 17 on the harbor wall 2. Instead of such an arrangement, the mooring attachment, for example, outside a port basin at a jetty or at a berth outside a port can be attached. In this case, the pilot line 3 is visible attached to a buoy and can be recorded there.

The watercraft 8 is attached to the rear of the stern rope 19 on the bollard 18 and the front side on the document ^¬ line 4 on the mooring 6, a chain attached, which in turn is anchored to the ground anchor 7. When fabricating ^¬ exempt document line 4 and their attachment to the front ship the Muringkette depends 6, and is, except for the visible parts in the water 5. In order to solve the vessel 8 from the anchorage, it is necessary to 6 to remove the Muringkette again, so To solve the document leash 4, so that then the tail line 19 can be solved and the vessel 8 can depart.

In order for the pilot line 3, when lying on the ground 16, to be able to be picked up without having to pull it through by hand, a boat hook according to the invention is present on board the watercraft 8. This boathook can, for example, have the characteristics illustrated in FIGS. 2, 3 and 4. The boat hook has a rod 1 which is fixed to a housing of a motor 11, a DC motor. On the housing of the motor 11, a bearing for the rotatable mounting of a roller 10 on the motor shaft 9 is also provided. This roller 10 has a V-shaped receptacle for the pilot line 3, which is drawn in the embodiment in Fig. 2 in cross-section ^{¬ a} . On the rod 1 is also a control element 12, via which the speed of the motor 11 on the one hand and on the other hand, the direction of rotation are tax ^¬ bar. At the upper end of the rod is a housing 13 for accumulators 14 used therein. The housing 13 should be designed to be removable, so that it can be inserted into a charging station of a power supply unit for recharging the accumulators 14. It goes without saying that the motor 11 must be waterproof, since it is immersed in the water 5 when detecting the pilot line 3 in the harbor basin.

Fig. 3 shows in a partial section a variant of a boat hook according to the invention; this one also has one

Roll 10, which is V-shaped and has roughened surfaces or notched surfaces with radial notches to accommodate the pilot line 3 better. The motor 11 is installed directly in the rod 1 in this embodiment. It may be a motor 11, as it is commonly used for shutters to this up and unwind can. The motor 11 has a worm and a shaft with a pinion on which the roller 10 is mounted, so that hereon the roller 10 in the desired manner to the left or to the right by appropriate reversal of the motor 11 can be rotated. The control is carried out via the provided controls 12. These are push buttons, via which, for example, the speed and the direction of rotation can be determined. In order to charge the batteries 14 which are arranged in the rod 1, a charging socket 15 is further provided, to which a charger of a known type can be connected. Another embodiment is provided in Figure 4 ^¬ that with respect to the formation corresponds to the example of Figure 2, but additional guide elements 20 has in extension of the edge surfaces of the roller 21 on ^¬, which are provided as surface elements and a U-shaped Carrier 22 protrude above. The U-shaped support is fixed to the motor flange of the motor 11, so that the roller rotates on the other hand. The The bar 1 facing guide element 20 fully bridges ^¬ constantly the gap between the roller 10 and the rod 1 It can be seen that such guide elements 20, 21 facilitate the inclusion of the pilot or document line. Furthermore, the rod 1 is marked as a separate rod ^¬ net, which is to be made clear that this can be configured arbitrarily long.
