Description
Motor vehicle trailer
The invention relates to a motor vehicle trailer with a removable top
and an interior that can be opened at the back.
The purpose of the invention is to design such a trailer for leisure
activities in such a way that it provides as complete and convenient a
solution as possible when the equipment involved is transported and
used.
In the solution to this problem proposed by the invention the hull of a
motor boat or another kind of boat is provided as the top, resting up-
side down on the walls of the interior, while a cover for the interior
is provided underneath the hull.
Although the equipment of trailers with fold-open tops and the provision
on the top of elements to secure the hull of a boat have been disclosed
:: :
in the past, the solution proposed by the present invention makes a com-
par~tively heavy top unnecessary. Even so, the trailer can still be
closed up after the boat has been removed.

The covering operation can be carried out particularly simply if in
accordance with the invention the cover is designed in the form of a
roller blind.
In an advantageous further development of the invention holding devicesare located in the interior of the trailer body to secure boat equip-
ment, one or two motor cycles, water-skis, surf-boards and/or other
leisure articles, such as camping equipment.
It is also very advantageous if in accordance with the invention at
least one longitudinally positioned, preferably U-shaped rail is located
on the inside of the floor, that is provided to hold the wheels of a
motor cycle.
This rail, two of which can of course be provided parallel to each other
as well, guarantees that the motor cycle is held in place securely. All
that is needed in addition are lateral supports which engage upper
sections of the motor cycle.
Extra stops at the front and the back effectively prevent the motor
cycle from rolling away.
It is also advantageous if in accordance with the invention an exten-
dable rail, the free end of which can rest on the ground when it is ex-
tended, is provided in the area of the motor cycle parking space,
preferably on the underneath of the floor.
Such a rail makes it particularly easy to load and unload the motor
cycle.
This loading and unloading of the motor cycle is facilitated considerably
if in accordance with the invention the extendable rail can be moved
longitudinally with a pivot bearing at the back end of the trailer.

In a further development of the invention a door consisting of one or
two parts with a vertical axis of rotation is located at the back of the
trailer.
The loading and unloading operations can be carried out particularly
simply with a door designed in this way.
It is, however, also possible in accordance with the invention that a
tail-gate which opens downwards and can be used as an access ramp is
provided at the back of the trailer.
It is also very advantageous if in accordance with the invention a door
is provided in one side panel of the trailer body, behind which storage
space is provided for preferably one outboard motor.
Outboard motors are relatively heavy, particularly when they are Rower-
ful; they can, however, be handled comparatively simply with the solu-
tion proposed by the invention.
They are made even easier to handle if in accordance with a further
development of the invention the outboard motor is attached to the door
and moves out when the door is opened.
Use of the trailer is made particularly simple if in accordance with the
invention rails that can be pulled out towards the back are provided in
the upper section of the two side panels of the trailer body as supports
to help in loading and removing the hull of the boat.
The boat is attached to the trailer in a particularly simple way if in
accordance with the invention hinged closure elements are provided in
the upper section of the trailer body that engage the hull and attach it
to the trailer.

It is also very advantageous if in accordance with the inventio~ a
cable winch, with which the boat can be pulled towards and onto the
trailer body, is located preferably in the front section of the
trailer.
To remove the boat, it is pushed towards the back and, when it reaches
the point at which it tips, it is lowered down and turned over its stern
so that is is the right way up for use. The cable winch is a great help,
particularly when the boat is being lowered and turned over. This is of
course even more the case when the boat is being loaded, when the ope-
rations are carried out in the opposite order. The cable winch can, how-
ever, also be used to pull the boat out of the water and to the trailer.
In a particular advantageous development of the invention the body of
the trailer is produced from FRP and is preferably designed to consist
of one single part.
This makes it possible to adapt the body to individual requirements.
It is also very advantageous if in accordance with the invention an
insert made of FRP is provided in the in~erior of the trailer, in which
the elements for holding the individual articles that are to be trans-
ported are moulded.
This feature has a particularly favourable effect on the design of the
interior.
One embodiment of the invention is illustrated in the drawings.
Fig. 1 is a side view of a motor vehicle trailer with the hull of a
boat in position as the top,
Fig. 2 is a.top view of the trailer and the bottom of the hull of the
boat,
Fig. 3 is a cut-away side view of the complete trailer and
Fig. 4 shows the inside of the floor with recesses to accommodate
counterbalancing weights.
:'
l in Figs. 1 and 2 is a motor vehicle trailer which is equipped in the
usual way with a chassis 2, a coupling 3, a support wheel 4 - the height
of which can be adjusted - and four wheels 5 arranged in tandem. A body
6, on which the hull 7 of a motor boat rests upside down to form a top,
is located on the chassis 2. A door 8, which facilitates access to the
front section of the trailer body, is located in the left side panel of
the body 6. A door that has two wings and is not visible in Figs. l and
2 is also provided at the back of the body 6.
In Fig. 3 the side panel of the body has been shown cut away, as a
result of which the equipment inside can be seen. An outboard motor 9
that is used to drive the motor boat 7 is located behind the side door
8. The two wheels of a motor cycle 11 are in a recess 10 in the floor of
the body that is made from FRP to have the appropriate shape, so that
the motor cycle is already held in place very securely. It can be
secured additionally by further supports not shown in the drawings that
engage the upper sections of the motor cycle ll. Fig. 3 also shows one
- open - wing 12 of a two-wing door, which provides access to the
interior of the body even when the hull is in position on top. A
single-wing door or a tail-gate that opens downwards can be provided
instead of this door.
A rail 13, which can be moved longitudinally and the free end of which
can be lowered to rest on the ground when it is extended, is located on
the underneath of the floor. It is of course also possible to provide
not only spaces for two motor cycles in the interior of the body but
also two extendabIe rails. Holding devices for further equipment not
shown in the drawing, such as water-skis, surf-boards, camping equip-
ment etc., which it is then practical to mould into the floor as well,
can also be provided in the interior. Since the body 6 can also be pro-
duced from FRP, it is possible to provide the inside of the body with
integrated holding devices for the different pieces of equipment as
well.
A number of hinged closure elements 14, which engage the hull (7~ and
attach it to the body, are located at the top edge of the trailer body.
To remove the boat, these closure elements are opened and the boat is
pushed back to the point where the hull tips. A cable winch 15, the
cable 16 of which is attached to the bow 17 of the boat, is located on
the section of the chassis 2 in front of the body, so that the tipping
of the boat can be carried out in a controlled manner. When the hull
slides back, this cable 16 runs on a guide roller not illustrated in the
drawing that is located at the top front edge of the body. It is prac-
tical if a roller 18 is fitted at each side of the top back edge of the
body, over which the hull can roll.
A roller blind 19, that can be pulled across the whole of the top sur-
face of the body, is provided to cover the interior when the hull of the
boat has been removed. The two side edges of this roller blind are
guided in rails 20,
The base of the body is also provided with the recesses 21 shown in dia-
grammatic form in Fig. 4, in which counterbalancing weights 22 that make
sure the trailer is kept in balance can be placed. This balancing opera-
tion is needed to guarantee that the trailer performs effectively when
pulled, in cases where only some of the originally planned equipment or
different equipment is being transported.
