Description

Multi-functional tent trailer with platform

The described invention relates to a new type of tent trailer in which an inflatable tent is mounted on a flat platform. Various kits (such as H, I, K, L) can be added to the tent trailer 5 so that the tent trailer can also be used as ao .:

Boat trailer (figure 2), catamaran trailer (figure 1), kayak trailer, surfboard trailer, motor trailer (figure 3), glider plane trailer, luggage trolley, etc. The current generation of tent trailers / folding trailers are not suitable for carrying larger and / or heavier items. The assembly of the kits can be done via supports (D) mounted on the trailer chassis (A & B) as well as on the upper platform panel (F). A luggage capacity of 1100 kgs. is easy to realize.

The current tent trailers / folding trailers require pegs and / or guy lines to be able to be used in harsh winds, which requires extra effort especially on stony or sandy soils and is not possible at all on some surfaces. The attachment to the platform replaces the need for pegs and / or guy lines. The own weight of the trailer with platform in combination with a tent shape and frame on which the wind has little control (igloo model) forms the basis for this. Other models and tent types can also be conceived for this invention, but the whole will be less storm-proof.

Setting up and breaking down can be completed in a few minutes with minimal effort. By sliding in / out, depending on the version 1037358 2 of the version, 2 or 4 box girders (P) in the tubes (D) under the trailer a supporting structure is created on which the upper plate is placed by means of hinges (G). The tent is thereby exposed and the air hoses (N) of the inflation tent are pressurized in a few minutes with a foot pump, compressed gas bottle or compressor, so that the tent is erected. The tent is then ready for use. Depending on the size of the base plate and the vertical load on it, drop-out or swing-out supports (M) can be applied in addition to the supporting box girders.

The thickness, stiffness and composition of the platform is adjusted to the size and load of the total construction. For larger platforms, thicker sandwich cores, whether or not in combination with stronger skin layers, will be used to achieve sufficient strength-stiffness. For handling and strength / stiffness, it is preferable to use lightweight sandwich constructions and for the strength, moisture resistance and service life of the platform, plastic composites are preferred. Other compositions of the platform such as timber sandwich structures are also possible but generally lead to suboptimal solutions.

In order to be able to store the tent (C) between the platform panels (E & F), the platform parts are mounted at some distance above each other by means of hinges (G). The distance between the panels is determined on the basis of the volume that the folded tent occupies.

When folding in the platform panels, the tent is confined between the fixed underlying (E) and the folding upper panels (F) and covered with it. Various objects can be placed on the upper panel for transport.

5 The type of chassis is not crucial for this tent trailer; it is possible both on a complete chassis and on a chassis with a draw triangle connected thereto by means of bolts or welding.

The applicant is not aware of the existence of any other tent trailer with inflatable tent mounted on a platform trailer. The patent under publication US 2007/0296246 A1 provides a conventional tent with metal frame on a platform that can be folded out lengthwise but not in width and does not have the stormproof and multi-usable properties and the ease of mounting of the present tent trailer .

The patent under US 2009/007948 Al provides for the possibility of transporting other heavier objects in the tent trailer, but not of the size and weight that is possible with this tent trailer. Moreover, under the relevant patent the tent trailer is not provided with a flat platform and the dimensions of the living area of the tent are extremely limited. Applicants are not aware of other tent trailer combinations with somewhat similar claims.

This tent trailer with inflatable tent can be set up in stormy weather without pegs and / or guy lines and can even withstand hurricane power (12 Bf). The tent is attached to the platform by means of a tent rail so that the forces are evenly distributed over the fabric and the platform; the forces here are considerably less than the point load instead of the point. pegs.

Because the platform is free from the ground, the tent can also be moved in set up condition.

The flat, free-standing floor space of the current tent trailers is limited to no more than a few square meters; with this tent trailer it is easy to realize a flat free-standing floor area from a few 10 square meters to approx. 38 m2, depending on the chosen tent size and the chosen platform trailer (see also figures 5b / 6b and 7b). A further extension of the tent on the ground is also still possible, but then pegs and / or guy lines are required.

The current tent trailers are designed for towing is passenger cars and / or vans; the concept of this tent trailer can also be easily applied for towing by a motorcycle or bicycle by adjusting the dimensions, weight and chassis.

The flat bottom of this tent trailer is suitable for integrating electric floor heating in the manufacture of the bottom panels by means of vacuum injection. As a result, people not only sleep free from the ground, which prevents rising cold, but also allows them to stay comfortably in colder situations.

The tent trailer can be provided with foldable side walls (not shown), preferably composed of lightweight composite material and a front which serves as a removable kitchen unit and an extendable rear wall that can serve as an extension of the tent trailer for transporting, for example, a longer mast. By linking the rear wall, side walls and front, a large-volume luggage trolley is created in which, among other things, the things for the holiday can be taken along so that the car can remain virtually empty.

The low weight of the empty tent trailer in combination with an adjustable maximum permissible mass makes it possible for this tent trailer to also be towed by small cars. On holiday with the tent and catamaran, for example, it is possible with almost every small car.

The tent can be set up with a foot pump, compressed air (diver's bottle) or a 12V or 230 Volt tire compressor in just a few minutes; depending on the wind strength, the air tubes can be inflated between 3 and 12 bar pressure.

As a basis for the platform, vacuum-injected fiber-reinforced plastic composite with lightweight sandwich core material is preferred in order to: 1. be able to give the platform sufficient rigidity and to be able to absorb the various loads 2. to save weight from the point of view of use and thus the unfolding of facilitate the tent trailer; 4. to obtain a good insulating floor from the user's point of view; 5. to save weight and therefore energy during transport from an energy point of view; 6. to have a sustainable product from an ecological and user perspective that is fully weather and moisture resistant and will last for decades.

Other materials for assembling the platform such as wood (composite), aluminum (composite) are also possible but lead i.h.a. to suboptimal solutions.

ïo Because the tent trailer is low, a good view to the rear is possible while driving and the air resistance is limited. The drawbar length of this tent trailer is i.h.a. considerably longer, increasing stability at higher speeds and facilitating reversing. Options such as movers under caravans, stabilizer couplings and the like can also be used with this tent trailer.

The possibility to use the tent trailer for multiple purposes prevents the expensive and space-consuming purchase of multiple types of trailers.

It is possible to tilt the tent trailer 90 degrees and move it on special rollers (O) so that the tent trailer takes up little space even when not in use.
