    BOAT SERVICE STAND
    OBJECT OF THE INVENTION The present invention relates to a boat service stand for use in washing, painting, repairing, or servicing a boat.
    BACKGROUND OF THE INVENTION Today, boats are repaired and maintained by turning small and light boats, such as rowing boats or small outboard engines, from the bottom up, and any outboard must, of course, be removed before turning. Large boats are lifted by a crane onto the boat's maintenance stands, which allows the boat's bottom to be serviced / repaired from below. The disadvantage of the current technology is that turning the boats around is difficult and requires more people, even if the boat is a light rowing boat. outboard motor, trolling rods, etc. all that can be damaged when turning the boat. Lifting large boats with a crane is expensive and separate service stands are also - expensive. Still, the work from under the boat is heavy because the hands have to be up during the entire work. The total cost of boat maintenance will increase, e.g. due to the use of a crane, and due to the slow progress of work due to the heavy working position. N 25 — PURPOSE OF THE INVENTION The object is that the boat can be serviced in the boat's maintenance rack by tilting the boat alternately in the desired direction, whereby the bottom of the boat is well exposed and thus easily repaired or serviced. a 8 30 = The above drawbacks can be eliminated and the above-mentioned object is achieved by a boat maintenance rack according to the invention, characterized by what is defined in the characterizing part of N protection claim 1, and preferred embodiments of the invention are the subject of protection claims 2 to 5.
    The most important advantages of the invention are that the boat can be serviced in the boat maintenance rack by alternately tilting the boat in the desired direction, whereby the bottom of the boat is well exposed and thus easy to repair or maintain. It is easy and quick to move the boat from the boat trailer to the boat service rack or even pull directly from the water or on land - to the boat service rack. Furthermore, it is easy to move the boat on the boat maintenance rack using the wheels of the boat maintenance rack. The boat's maintenance rack can be fitted with wheels known from car trailers, so the boat's maintenance rack can be easily moved by car, even in soft terrain. It is clear that the use of the invented boat maintenance rack achieves great savings in boat maintenance.

S Body 1 consisting of a lower body 1a, an intermediate body 1b and vertical bodies 1c.
    There are preferably two lower frames 1a at a distance from each other, the length of the distance is determined by the length of the boat to be serviced, the distance can also be adjusted, e.g. by means of nested tubes. The spacing length may be 1000 to 3000 mm, but as said spacing length is determined by the length of the boat, so it may be of some other known length. The lower frames la have ends laa, top lab, underside 1ac and sides lad. The figures show that at both ends of the lower hulls 1a there are z-shaped bends which make it easier to attach the wheels to the ends 1a so that the lower hulls 1a do not rise high from the platform on which the boat service rack is mounted, making it easy to move the boat from the boat transport trailer to the boat service rack. on. Unlike the figures, the frame 1 can also consist of a single rectangular plate bent from opposite sides in the shape of the letter z.
    - Two parallel lower frames 1a are connected to each other by two or more intermediate frames 1b which are screwed or welded at their ends to the lower frames 1a, preferably to the sides 1ad of the lower frames, forming a square or rectangular frame when viewed from above. The intermediate frames 1b can also be bent outwards in the middle, whereby the lower frames 1a and the intermediate frames 1b form a barrel-like structure when viewed from above.
    The intermediate bodies 1b have one or more vertical bodies 1c above them. The vertical body 1c may be perpendicular to the upper surface of the intermediate body 1b welded or screwed. The vertical hull Ic is best in an oblique position deviating from the vertical position by 5 to 45 degrees, being parallel to the slope of the sides of the boat, as a result of which the length of the lower hulls 1a may be shorter.
    N 25 - At the upper end of the uprights 1c there is a boat tilt 4 which is a boat winch. The boat winch may not be the so-called linen winch or wire winch or string winch. The boat tilter 4 has a guide 4a, N at the end of which there is a known hook. The guide 4a is a cloth, wire or string.

    USE OF THE INVENTION AND SOME ALTERNATIVE STRUCTURAL SOLUTIONS The hull 1 of a boat maintenance rack is made of a rectangular 100x40x3 steel tubular beam according to an alternative construction. The lower frame 1a of the frame 1, at both ends 1a of the lower frames 1a, has wheels 5, two of which are fixed 200 mm carriage wheels, two swiveling and lockable 200 mm carriage wheels, and two 200 mm cam wheels 6, which are the above-mentioned wheels. 5 next door. The body 1 moves agilely by means of these wheels 5 and cam wheels 6 and is easy to move from one place to another and can be tilted slightly by means of these cam wheels 6.
    The central idea in this boat service rack is that if the boat 7 needs to be washed, serviced, painted or repaired and does not want or can do it on the boat trailer, then the boat service rack can be taken behind the boat trailer and the boat 7 can be pulled from the boat trailer to the boat service rack. winch 8 and tilt the boat so that - the bottom of the boat is easier to see. The boat maintenance rack is thus placed behind the boat trailer in the same line in the longitudinal direction and in the height direction, this is accomplished by means of the boat maintenance rack wheels 5 and cam wheels 6. The wheels 5 of the boat maintenance rack are then locked and the trailer winch is unlocked, but the hook is not yet removed from the bow of the boat 7. Next, the hook at the end of the winch 8 drawstring or N 25 wire or rope on the drawbar 10 of the boat maintenance rack is attached to the rear of the boat 7 and the boat 7 is not started to be ripped back to the boat maintenance rack. According to a structural solution, the boat maintenance rack has two tilting arches 3e bent from a 40x40x3 mm steel tube beam, both of which are fitted with boat supports 3c. According to a structural alternative, the two heeling arches 3e are connected to each other by a 40x20x2 mm 8 30 pipe at three points, i.e. at the ends of the arches at the upper intermediate supports 3a and in the middle at the lower intermediate support S 3b so that they are successive bends 3e. 1500 - 3000 mm (distance) at a distance from each other depending on the length of the boat 7. The middle lower intermediate support 3b, e.g. on a 40x20x2 mm pipe, is welded as a reinforcement
    40x40x3 steel tube and on top there is a length adjustable transfer wedge roller 3ba.
    This assembly of tilting arches 3e, upper intermediate supports 3a, lower intermediate support 3b, boat supports 3c, transfer keel roller 3ba and possible halves 3d, the tilting arch structure 3 rests on the lower frames 1a of the hull 1, on both sides of the longitudinal centerline 2 of the lower hull 1a so that this curved part of the tilting arc 3e remaining on the rollers 2b moves in the longitudinal direction of the tilting arc 3e on the rollers 2b rotating transversely to the tilting arc 3e, whereby the tilting arc 3e tilts from side to side.
    The boat 7 is placed on top of the boat maintenance rack so that its center of gravity is in the longitudinal direction in the middle of the boat maintenance rack.
    Thereafter - the boat 7 is fastened, taking into account the weight of the boat 7, with fasteners 7a (load straps) of sufficient strength to the points or fasteners in the heeling arcs 3e, such as the upper intermediate supports 3a, the lower intermediate support 3b and the brackets 3d.
    After attaching the boat 7, the winch of the boat trailer can be removed from the bow of the boat 7, after which the trailer is pulled further away from the boat service rack.
    The boat service stand is lowered on the fixed wheels 5 with cam wheels 6.
    The boat's service stand must not be moved on the cam wheels 6.
    After lowering the wheels 5, the boat 7 with its boat maintenance racks can be moved to the desired location and maintenance can be started.
    The boat 7 is tilted by boat tilters 4 mounted on both sides of the boat maintenance rack body 1 (with winches), the hooks of which are attached to the tilting arch structure 3 to a bracket in the structure.
    The second boat tilter 4 is released and the other is wound, depending on which side of the boat 7 is to be serviced.
    When it is desired to tilt the boat 7 in the other direction, the lock of the boat tilter 4 is also released from the side on which the boat is tilted and held at the same time by the winch handle and the winch is rotated in the opposite direction to the tilting stage, then the boat 7 returns to the horizontal position. - N 25 - is safe and controlled.
    The boat service bracket has a quick-release drawbar eI 10 with a winch 8 for towing the boat 7 to the boat service bracket and a towbar 9 N (ball coupling) for connecting the vehicle to the towball.
    Quick-release drawbar 10 - according to a construction option, consists of two rectangular steel beams of different sizes and nested E, perforated at 80 mm intervals with four 27 mm 8 30 holes, and a 25 mm thick steel shaft inserted through the holes, the steel shaft locking in place with a known ring pin.
    After servicing the boat 7, it is easy to take the boat 7 back into the boat trailer, place the boat service rack behind the boat trailer, lock the wheels 5 of the boat service rack, attach the boat trailer winch to the bow of the boat 7 and remove
    rotating the overhanging fasteners 7a (load slings) of the boat 7 from the tilt arch 3e / tilt arch structure 3 and winch the boat 7 onto the boat trailer. The invented boat maintenance rack can be manufactured by known metal construction techniques, - using known manufacturing methods, raw materials and components. It will be apparent to those skilled in the art that the exemplary embodiments set forth above are relatively simple in structure and operation for the sake of clarity of description. Following the model presented in this utility model application, it is possible to produce various well-structured solutions which utilize the inventive idea presented in this utility model application.
