ADVANTAGE - Is foldable, easy to use and store.

Description

The invention relates to a removable, foldable trailing roller with an adjustable loading surface and an adapter to adapt to different frame profiles and frame dimensions for mounting on prams, handicapped vehicles and other vehicles.

The object of the invention is to provide an easily removable, trailing, fold-up, simple design roller for use on strollers. Be disabled vehicles, shopping carts and other vehicles to indicate when not in use folded, used to transport loads.

Bicycle trailers, motorcycle trailers, and other towable trailers are known for Vehicles. A disadvantage of the known constructions is that the manufacturing effort is relative is large and the devices are bulky to transport and store when not in use.

The solution according to the invention provides a foldable trailing roller on a vehicle removable to assemble with

• - a non-slip surface,
• - a circumferential edge protruding from the storage surface,
• - a removable, disassembled or foldable railing,
• - a pull-out bed that is adjustable in size,
  • - approximately in the middle of the loading area with a trailing roller,
• - a suspension device,
• - an adapter
  • - to adapt to different frame profile distances of the towing vehicle,
• - a swivel and locking device for folding when not in use, is provided.

For the transport of loads (shopping bags, packages), unwilling small children, and others, loads appearing to be difficult to handle in pedestrian traffic are available to the user a stroller usually except one, located under the stroller, spatially Restricted basket or a hookable net hardly any aids are available.

The device according to the invention makes it possible to transport loads of size if required  and weight cannot be transported under or on the stroller.

The device according to the invention consists of a provided with a non-slip covering or accesible trailing roller with a revolving over the height of the storage area protruding edge.

This edge is with receptacles for fastening a railing or parts of a railing Mistake.

Below the changeable loading area no. 1 and 2, one is trailing taken role. No. 3 (swivel castor), which is dimensioned so that the loads to be transported can be worn easily. The role is convenient with a pneumatic tire or equipped with a soft rubber tire. A lockable roller (brake roller) is optionally used.

The steering process is effected in that the trailing roller on the towing vehicle in two Joints point 1.1 stored, is guided through this in the longitudinal direction.

The platform is mounted by hanging or screwing it onto one of the vehicle frames No. 5 mounted receptacle, no. 4 (adapter) with a hinge picture 4, for folding up Not used Fig. 3, with a lock Fig. 3, no. 4.5, is provided.

The functional elements for locking the folded-up platform are fittings that are attached to the Frame of the vehicle and on the platform or preferably on the adapter and on the platform are attached.

The balance between the vehicle frame profile to which the mount is attached and the Cradle is made by adjusting the mounting piece, or optionally by a Adapter piece made of a deformable, elastic material that ensures a safe, Guaranteed non-slip connection between the mounting piece and the vehicle frame profile.

The divided border of the, also divided loading area is equipped with a lockable, extendable area provided with a part of the loading area overlapping the loading area is provided.

An example of the device according to the invention is shown in four complementary figures shown.

Picture 1 shows the platform picture 1, no. 1, 2, 3 in the folded state, on the frame picture 1, no. 5  of a towing vehicle. The pull-out part picture 1, no. 2nd, is from the inclusion of the loading area picture 1, No. 1, pulled out.

Fig. 2 shows an enlarged view of the platform Fig. 2, no. 1, 2, 3, in the folded state, on Frame picture 2, no. 5, a towing vehicle. The pull-out part Fig. 2, no. 2, is from the recording the loading area Fig. 2, no. 1, pulled out and in the safety holes, Figure 2, no. 2.2, by means of a spring Fig. 2, no. 1.5, locked in these safety holes Pull-out piece. The platform is around the axis, Figure 2, no. 4.4, pivoted. The roller, picture 2, No. 3.1, is trailing in the geometry of its recording and fulfills in a planar Bearings, Figure 2, no. 3.3, and para. 3.2, preferably by a planar deep groove ball bearing The steering function is made of plastic.

Fig. 3 shows an enlarged view of the platform Fig. 3, no. 1, 2, 3, when folded up, on the frame Fig. 3, no. 5, a towing vehicle. The pull-out part Fig. 3, no. 2, is in the Image of the loading area Fig. 3, no. 1, pushed in and locked. Through the swiveling Security device Figure 3, no. 4.5, the platform is secured against falling.

Figure 4 shows the mounting bracket, consisting of a divided bracket, Figure 4, no. 4.2, in which the Bearing shaft picture 4, no. 4.4 is rotatably mounted. To adapt to different distances of the Frame profiles Fig. 4, no. 5, the mounting brackets are Fig. 4, no. 4.2, on the bearing shaft picture 4, No. 4.4, movable. After assembly, the platform guide is in the middle position by the Collars Figure 4, no. 4.6 set. The coupling pieces, Figure 4, no. 4.3, are to adapt to different frame profiles Fig. 4, no. 5, made of an elastic material or with a deformable bush made of such a material (for example rubber).
