Description

Boat slip
The present invention relates to a boat slip comprising an outer frame equipped with a number of support wheels arranged in parallel on each longitudinal side of the frame and which is arranged to support the boat and also a winch to pull in and launch the boat into the sea. A traditional boat trailer that can be pulled by a vehicle comprises, besides standard wheels and a towing hook, a frame with support wheels for a boat. During use of such a boat trailer, it must be driven out into the water until the boat has buoyancy, and the boat is thereafter released with the help of a winch or the like so that the boat floats off the trailer. The pulling up of the boat is carried out in a corresponding way.
As the boat must, as mentioned, have a buoyancy during the use of a such trailer, the trailer must be reversed out into the water, but preferably not too far out so that the water, and then in particular seawater, comes up to the hub of the wheels, as this can damage the ball bearings in the hub. Furthermore, the brakes on the trailer can also be damaged or ruined, which can be dangerous for later use .
Another problem is that it should not be too steep or rugged or too large a difference in the water level at the location of the pulling up or launching into the sea. It is often not so simple to find a suitable place to use the boat trailer and one is often dependent on a slipway, which has, for example a solid foundation. From patent literature, reference is made to US462616A where a type of a waggon is known, formed as a crib that supports the boat and which is equipped with wheels. The waggon can be driven out from and onto the trailer with the help of a winch, and in the driven out position a rear part of the waggon rests on the foundation. The waggon is tilted at its forward part. Furthermore, the trailer on which the waggon rests can rotate in relation to the forward towing rod that is fastened to a vehicle.
Furthermore, reference is made to US20100247279 Al, which relates to a solution with telescopic frames that can be driven in and out with respect to each other, a motor to drive a belt truck, a winch and several rollers. However, the whole set of telescopic frames for the driving out of the boat is angled, and not such as in the present invention, where the frames when they are driven out from the outer frame are arranged at an angle with respect to the outer frame so that at least one outer frame part extends down into the water.
Therefore, it is an object of the present invention to provide a boat trailer with an in-built slip so that, for example, launching into the sea and pulling out of the sea of a smaller boat can be carried out from a pier. This can be carried out even if there is many meters difference between the water level and the height of the pier and where the trailer is standing safely on the dry land. It is also a further problem for some boat house owners that the sea bed outside the boat house is not optimal for laying down rails for a standard slipway, for example, if the sea bed drops very sharply outside the boat house or the pier. In this case, it is common to drive the boat out from the boat house on an appropriate waggon and
thereafter use a rotating crane to hoist the boat up from the waggon and place it down on the water. A corresponding procedure has been used to get the boat back into the boat house.
Thus, it is an object of the present invention to provide an extendable slipway that can be placed on land, and which means the above mentioned problems are avoided.
Said objects are realised with a boat slip as given in the subsequent claims, in that the outer frame comprises a number of telescopic frames, where said telescopic frames are equipped with a number of support wheels placed on each longitudinal side of the respective frame, and which are arranged to support the boat during launching and pulling in, where said telescopic frames are driven into the outer frame, when in a parked position, and during launching and pulling in of the boat, the frames are driven out from the outer frame, and arranged at an angle in relation to the outer frame so that at least an outer frame part extends down into the water, whereby the boat is arranged, with the help of the winch, to be lowered or pulled over the telescopic frames and in or out from the outer frame, and that, in the extended position, the outermost of the telescopic frames is equipped with a float.
Alternative embodiments are given in the dependent claims.
The outer frame can comprise rails that are formed with a C-profile, and said telescopic frames can comprise rails that are formed with a C-profile and which are equipped with a number of pulley wheels. One of said telescopic frames can be a mid-frame arranged to roll with the pulley wheels inside the C-profile of the outer frame. Furthermore, one of said telescopic frames can be an inner frame arranged to roll with the pulley wheels inside the C-profile of the mid-frame. Said
C-profiles can be equipped with stoppers at each end.
The rails of the outer frame can, in a rear part, comprise an angled and downwardly directed section.
Furthermore, the boat slip can be equipped with a winch for driving in and driving out said telescopic frames, comprising a wire with two wire parts that are wound in separate direction about a drum of the winch, where said wire runs from the drum and to a junction on the inner frame, further on round two opposite facing pulleys on each end of the mid-frame, and thereafter round a pulley at the end of the outer frame and back to the drum.
In one embodiment the outer frame can be equipped with a number of wheels on each side, and also a towing hook arranged for the fastening to a trailer fastening on a vehicle, whereby the boat slip is arranged to function as a boat trailer.
In another embodiment the outer frame can be arranged for fastening to a foundation, such as on a pier or in a boat house .
The invention shall now be described in more detail with the help of the enclosed figures, in which:
Figure 1 shows the invention in an extended state.
Figure 2 shows the invention in a driven-in state. Figure 3 shows in more detail a rail arrangement for use with the invention.
Figure 4 shows in more detail a winch arrangement for use with the invention.
Figures 1 and 2 shows a simplified principle diagram of the invention. As can be seen the present invention can, if it is used as a boat trailer, comprise an outer frame 1 equipped with normal wheels 11 and a towing hook 20 for connection to a trailer fastening point of a vehicle.
Furthermore, the trailer can be equipped with connections for the lights and brakes of the vehicle, as is common for trailers. A typical, known winch (not shown) can also be arranged for the launch and pulling in of the boat in a known way.
The invention can also be mounted permanently to a foundation, such as a pier or in a boat house and will then normally be without the wheels 11 and towing hook 20. Otherwise, the construction will, in the main, be the same for both variants.
As can be seen in figures 1 and 2 the outer frame 1 is, in the main, built in a traditional way in that the outer frame 1 comprises a number of support wheels 7 mounted on each longitudinal side of the frame. In the figures, this is shown as upwardly extending rods equipped with roller wheels. Corresponding roller wheels can be used on all rods. The support wheels can also be formed as familiar standard self-adjusting support wheels. The purpose of the support wheels is to support and secure the boat (not shown) when it lies on the frame. In addition to the outer frame 1, the invention comprises at least one telescopic frame 2, lying inside, here given as the mid-frame 2, and can further comprise an additional frame 3 lying inside, which is given as the inner frame 3. Further, not shown telescopic frames can also be used to increase the length. In particular, the outer frame 1 and the mid-frame 2, but also the inner frame 3, are preferably constructed on the longitudinal sides by rails la, 2a, 3a with a C-profile so that respective pulley wheels 5 can roll inside the C- profile of the outside-lying frame, as shown in figure 3. Alternatively, the inner frame can be constructed by square pipes. In addition, said rails can be equipped with stoppers 6 at each end. The end 19 of the C-profile la of the outer frame 1 can be bent downwards either in that the whole of the end of the rail is placed at an angle or in that the end of the rail opens out in a V-form, where the upper part of the V lies, in the main, horizontally while the lower part is tilted downwards. The purpose of the tilted end part 19 is that the extended frame part 2,3 can be set at an angle downwards when driven out. The end part 19 can be equipped with an adjustment appliance (not shown) so that the angle can be regulated, either before, after, or during the pushing out/pulling in of the frame parts. The rails can be made from steel, and preferably stainless steel, but can also be made from aluminium or other material.
It can also be imagined that the rails can be made from square pipes, though with decreasing dimensions so that the inside-lying telescopic parts have a smaller dimension than the telescopic part lying outside. In this context gliding or rolling appliances can also be provided to ease the telescopic movement, and the square pipes can possibly be equipped with roller wheels. This can be relevant for land-based slipways, but can also be used for a trailer. The mid-frame 2 and the inner frame 3, and any additional telescopic frames, are equipped in a way corresponding to the outer frame 1 with support wheels 8,9 with
corresponding roller wheels as described above, mounted on each longitudinal side of respective frames. However, when the boat is parked in the outer frame 1 the purpose of the support wheels 8,9 is not to support the boat as these wheels will normally . have a lower height than the support wheels 7 of the outer frame 1 so that the roller wheels shall not come into conflict with the boat during the pulling in of the telescopic frames (the slipway) . The support wheels 8,9 of the mid-frame 2 and the inner frame 3 are primarily used to roll out or roll in the boat during launching or pulling in. However, the height of the support wheels 8,9 can, if required, be dimensioned so that these too, at least to some extent, support the boat. Normally, the support wheels 7 of the outer frame 1 will be mounted somewhat higher than the support wheels 8,9 and be arranged in increasing height seen from the rear.
To move the frames 8,9 from a parked position, as shown in figure 2, to an extended position, as shown in figure 1, a separate winch 16 can be used. The winch 16 can be operated manually or be electrically driven. Here a wire with two wire parts 12, 13 can be used, which are wound in different directions about a drum 16a of the winch, as shown in figure 4. One wire end 12 runs from the drum 16a and to a securing point 15 on the inner frame 3. From the securing point 15 the wire runs further round two opposite facing pulleys 14 at each end of the mid-frame 2, and thereafter round a pulley 14 at the end of the outer frame 1. Then, the wire end 13 runs back to the drum 16a. During the pushing out of the telescopic frame parts the drum 16a is rotated anti-clockwise. The wire end 13 will then pull in, while the wire end 12 is released, and this leads to the wire pulling at the securing point 15 and pulling the inner frame 3 outwards. When the inner frame 3 reaches it extreme position it pushes against the end of the rail 2a of the mid-frame 2 and pulls the mid-frame 2 along. The mid-frame 2 stops the pushing out when it reaches the end of the rail la of the outer frame 1. The telescopic frame parts are now fully extended, but they can be stopped in any other position if required. It can also be imagined that other arrangements can be used for the pushing out and pulling in of the frame part, for example,
mechanically or hydraulically driven systems. During the pulling in of the telescopic frame parts 2,3 the operation is reversed, i.e. the drum 16 is rotated clockwise so that the wire end 12 pulls at the securing point 15 and pulls the inner frame 3 into the mid-frame 2, which in turn pulls in the outer frame 1. The direction of rotation of the drum 16 depends on how the wire is wound, so that anti-clockwise or clockwise is not essential.
When using the invention, to launch a boat, the telescopic frame parts 2,3 are pushed out as described above, until the outer part 18 of the inner frame 3 is in the water. The outer part 18 can be equipped with a float 10 or the like. Thereafter, the boat is launched in a normal way from the outer part 1 and over and down along the
telescopic frame parts until the boat floats on the water. Thereafter, the frame part can be driven in again as described. In the pulling up of the boat, the operation is carried out in the same way, i.e. the frame parts 2,3 are pushed out first and thereafter the boat is pulled up. When the boat is placed in the support wheels on the outer frame 1, the frame parts 2,3 are pushed in as described.
The use of a float 10 is advantageous, in particular when the invention is used as a boat trailer, but also when used as a land-based installation, as the float floats on the water so that the weight of the boat rests on it and the wheels 11 of the boat trailer itself. Then there will be no heavy large load on the trailer fastening point of the vehicle, or the fastening points ashore.
