The The invention relates to an air cushion boat model, in particular a remote controlled Airboat model, with an air chamber and a kit for such a Hovercraft model.

One Vehicle model represents a miniature replica of a vehicle For example, ship models serve smaller replicas of a Watercraft such as a ship or a submarine. vehicle models usually do not provide a complete replica of the original Vehicle, but form the outer appearance of the original vehicle with different levels of detail. Challenging vehicle models form next to the pure external appearance the original vehicle also functions, in particular also movement functions of the original vehicle. Such vehicle models are usually remote-controlled.

When Modeling is the production of a concrete, three-dimensional, physical object. Commonly known as model airplanes and model helicopters trained models. The construction of such model airplanes or model helicopter is distributed in the context of model making operated as a hobby, the aircraft models both as a compact Prefabricated as well as a kit are available. This can both the reduced and simplified replica of a real or planned model. You can distinguish here between in usually remotely controlled functional models where a function is modeled, and floor models, where usually a highest possible Degree of realism in the reproduction of one of the manifestation of the original.

Such Model aircraft fly without passengers and differ from each other z. B. by the nature of their control. There are free-flying ones Models that fly without a control, linen-controlled model aircraft, where the plane over a control line is operated, and remote controllable aircraft models. One remote-controlled model is with a transmitter and with a model of the aircraft receiver equipped, being over the transmitter wirelessly sends control signals (eg radio signals) to the receiver become. The recipient controls starting from the electrical and mechanical drive and control devices on, the z. B. move the rudder surfaces or actuate the drive. Under such a remotely controllable model is therefore a mobile Model to understand. The present invention as well as its basis underlying problem will be explained below with reference to mobile model vehicles.

Radio controlled Vehicle models are manually accessed by a user via a remote control via a Radio signal in its movement or in other functions remotely controlled. Such a remote-controlled vehicle model is used in addition to the pure entertainment of the user also often for training purposes. For example a user can use a radio-controlled vehicle model work out later to control a real vehicle better. Become more in one environment remote-controlled vehicle models controlled by different users, In addition, the user can be behavior towards other users by operation train his radio-controlled vehicle model. A sophisticated Remote radio-controlled vehicle model is therefore designed such that it the driving behavior and other functions of the original vehicle preferably realistically depicts.

Next the above model aircraft, d. H. the model airplanes and Model helicopters, also exist other model vehicles, such as z. As model ships, motor vehicle models, etc.

One Vehicle that can be moved on both the water and in the country is, is the so-called hovercraft, which also serves as a hovercraft or hovercraft is called. A hovercraft is a vehicle carried by an air cushion or air cushion becomes. In this type of vehicle, the hull is all around with a flexible apron Mistake. By a blower is a permanent air cushion wrapped around the flexible apron Boat hull built. The hovercraft hovers on this air cushion in operation virtually without contact over the Ground or the water. Their drive is done with propellers or Impeller and the control is done with Luftrudern, similar to the Tail planes on airplanes. Such hovercraft become the Transport of persons and objects or even in the racing sector used as so-called race air cushion boats. Currently exist Hovercraft only original. Self-propelled, remote controlled hovercraft in model design exist but not yet.

Becomes the conventional one Hovercraft operated on land, so it lies on the ground provided that the required for generating the air cushion drive is off. If the hovercraft is operated on the water, The hovercraft typically has one outward completed boat body on, which ensures a sufficient buoyancy for the hovercraft, so that a hovercraft even without the presence of a Air cushion floating on the water.

However, this is designed for remote controlled hovercraft in model construction as not possible or at least extremely expensive, which in the past meant that designed as hovercraft vehicle models have not been realized. The particular problem presented here in particular its Wassergängigkeit with switched off drive to produce the air cushion.

How to get out 1 can recognize, has the air cushion boat model shown there 1 a hull 2 on top of an upper hull 2A and a lower hull 2 B exists, as can be seen from the side view 2 can recognize. At the upper boat body shell 2A is also a half cylinder 2C attached as an air guide device, which is also referred to as duct. In the duct 2C becomes a (in 2 Shown) Thrust motor 9 provided with propeller, which to drive the hovercraft model 1 serves. Next to the on the duct 2C provided rear thrust engine 9 is in the upper hull shell 2A a lifting motor 3 let in, the ambient air transported by propellers in a pressure chamber. In addition, the upper hull shell points 2A below the duck 2C a tub 2D , which is provided for receiving a control electronics. How to get in 1 can be further seen, the lower hull shell 2 B in the air cushion boat model according to the invention 1 from an air chamber 4 with an elastic outer wall or an apron 5 enclosed.

The side view in 2 shows the hull 2 of the air cushion model 1 without the outer wall 5 , The lift engine 3 is through an essay 7 covered, in which holes or holes 8A . 8B . 8C . 8D through which the lifting motor 3 Aspirates ambient air and into a (in 3 illustrated) overpressure chamber 12 promoted. In the duct 2 is the thrust engine 9 mounted, which sucks ambient air from the front by means of a propeller and to control flaps or Luftruder behind 10 passes. The air truder 10 are transversal to the direction of travel of the airboat model 1 pivotable and serve to control the direction of travel of the hovercraft model 1 ,

How to get in 2 can also be seen in the lower hull shell 2 B Supply holes or supply recesses 11A . 11B . 11C . 11D . 11E provided over which the air chamber 4 as they are in 3 is shown, is supplied with air. The number and size of supply holes 11 May vary depending on the size and type of air cushion model 1 vary. In one possible embodiment, supply bores are 11 by a user when building the hovercraft model 1 partially or completely closed by means of a closure member to the pressure in the air chamber 4 adjust as needed. The lift engine 3 as well as the thrust engine 9 are via control electronics that are in the tub 2D the upper hull shell 2A is mounted, preferably controlled separately. This control electronics also has a Emp catching unit for receiving radio control signals for controlling the two motors 3 . 9 and a helm. In a preferred embodiment, the speed of the two motors 3 . 9 each adjustable. The higher the speed of the lifting motor 3 is set, the more ambient air is in the in 3 illustrated overpressure space 12 promoted. The overpressure room 12 gets through the upper hull shell 2A and the lower hull shell 2 B educated. How to get out 3 can recognize is the hull 2 preferably constructed symmetrically. The supply holes 11 are in a side wall of the lower hull shell 2 B intended. The supply holes 11 connect the outer air chamber 4 with the inner overpressure space 12 of the hull 2 ,

The outer wall or apron 5 the air chamber 4 consists of an elastic material, such as a plastic. The elastic outer wall 5 has an upper edge 5A and a bottom edge 5B on. The upper edge 5A the outer wall 5 is how in 3 shown in the air cushion boat model according to the invention 1 between the upper hull 2A and the lower hull shell 2 B trapped. The upper hull shell 2A and the lower hull shell 2 B are preferably also elastic and can in an air cushion boat model according to the invention 1 be releasably connected together via a clamp closure.

In one possible embodiment, a U-shaped outer edge of the upper hull Bowl 2A over the edge of the lower hull 2 B slipped, as in 4 shown. Between the upper hull shell 2A and the lower hull shell 2 B can be clamped by the user, the elastic outer wall. The upper edge 5A the outer wall 5 is thus detachable with the hull 2 connected. Unlike the top edge 5A the outer wall 5 is the bottom edge 5B the outer wall firmly to the lower hull shell 2 B attached, as in the 3 . 4 is shown. The connection between the bottom edge 5B the outer wall 5 and the lower hull shell 2 B is preferably waterproof. In one possible embodiment, the lower edge 5A the outer wall 5 to a bottom wall of the lower hull shell 2 B glued, as in the 3 . 4 shown. In alternative embodiments, the lower edge is 5B the outer wall 5 with the bottom wall of the lower hull shell 2 B fastened by means of a clip connection, a Velcro connection or by means of a screw connection.

In addition to the supply holes 11 are in the lower hull shell 2 B furthermore ventilation holes or venting recesses 13 provided, as in the 3 . 4 shown. The bottom wall of the lower hull shell 2 B is preferably two in the longitudinal direction of the hull 2 extending conical indentations or grooves 14 provided on the top of the vent holes 13 are located. The grooves 14 are designed so that the vent holes 13 on a ride on the hovercraft model 1 above a water surface above the waterline. This can prevent water in the pressure chamber 12 penetrates.

4 serves to explain the operation of the air cushion model according to the invention 1 , Through propeller blades passing through the hoist motor 3 are driven, ambient air is sucked in and into the pressure chamber 12 promoted. The in the overpressure room 12 Air located escapes on the one hand on the side wall of the lower hull shell 2 B provided supply holes 11 in the air chamber 4 and on the other hand via the vent holes 13 in the longitudinal direction of the boat body extending indentations or grooves 14 , The incoming air expands from the outer wall 5 or the apron 5 surrounded air chamber 4 until there is a pressure balance between the pressure in the air chamber 4 and the overpressure room 12 forms. Sudden overpressure in the air chamber 4 for example, by collision of the hovercraft model 1 With a solid object arises, can also over the upper clamp connection of the upper edge 5A the outer wall 5 between the upper hull shell 2A and the lower hull shell 2 B escape, as in 4 is shown schematically.

The over the vent holes 13 escaping air passes from the grooves 14 transverse to the direction of travel of the hovercraft model 1 laterally outward, being between the bottom wall of the lower hull shell 2 B and forming an air cushion, which is the model of the airboat 1 against gravity. The subsoil may be a solid land surface or a water surface. Due to the laterally escaping air flow below the lower hull shell 2 B thus creates an air cushion on the model of air cushion boat 1 remotely movable both over water and over land.

The ventilation holes 13 In one possible embodiment, they are provided with a protective grid which prevents the penetration of dust particles into the hull 2 prevented.

The bottom edge 5B the outer wall or the apron 5 is how in 4 shown fixed to the bottom wall of the lower hull shell 2 B waterproof connected. This will be during a movement of the hovercraft model 1 over water prevents water from entering the air chamber 4 penetrates. The detachable connection 5A the outer wall 5 or the apron 5 by pinching between the upper hull 2A and the lower hull shell 2 B simplifies the assembly of the airboat model 1 by a user. During assembly, a user can first of all the indissoluble connection of the lower edge 5B with the lower or bottom wall of the lower hull shell 2 B and then the top edge 5A between the upper hull 2A and the lower hull shell 2 B terminals. In one possible approach, the bottom edge is first 5B to the lower hull shell 2 B glued and then the top edge 5A between the two hulls 2A . 2 B clamped. In this way it is also possible an already mounted outer wall 5 or a mounted apron 5 exchange. The apron or outer wall 5 can be made of any elastic material, such as plastic or rubber.

In one possible embodiment, the outer wall 5 additionally at least one inner flap for receiving one or more buoyancy bodies. These buoyant bodies can be used by the user when mounting in the inner flap of the outer wall 5 be inserted and give the hovercraft model 1 , especially when moving over a water surface, an additional buoyancy. The buoyancy bodies may be hollow bodies or solids with less physical density act. As a hollow body, for example, serve an inflatable rubber hose. Alternatively, the buoyancy bodies may also be made of a material whose density is less than the density of water. In one possible embodiment, these buoyancy bodies are made of styrofoam, wood or foam.

The air chamber 4 can the lower hull shell 2 B completely or partially enclose. In one possible embodiment, the air chamber 4 divided into several sub-chambers, which have different supply holes 11 be supplied with air. A subdivision of the air chamber 4 in several sub-chambers prevents damage to the air chamber 4 a sinking of the hovercraft model 1 under the water surface.

In one possible embodiment, the supply holes 11 Flaps on, resulting in damage to the apron 5 close when water enters the air chamber 4 penetrates. These protective flaps are made of styrofoam, for example. These protective flaps prevent water from damaging the outer wall 5 or the apron in the pressure chamber 12 penetrates and so the airboat model 1 sinks.

The hull of the boat 2 at least partially enclosing air chamber 4 provides protection against mechanical impact of the airboat model 1 against a solid object. The air chamber 4 provides a protective cushion against mechanical damage to the hull 2 and gives the airboat model 1 further buoyancy. The airboat model 1 as it is for example in 1 may be due to the rear thrust motor 9 who is in the duct 2C is intended to move remotely over air or over water at a relatively high speed. In one possible embodiment, speeds in excess of 50 km / h are achieved.

Meets the hovercraft model 1 at such a high speed on a solid object insulates the air chamber 4 the mechanical impact, while in the air chamber 4 resulting overpressure over the supply holes 11 and on the inside of the top edge 5A in the overpressure room 12 can escape. Will the outer wall 5 or damage the apron in a collision with a solid object during a trip over water, also prevent protective flaps, which the supply bore 11 close automatically, a penetration of water into the pressure chamber 12 so the air cushion model 1 does not sink. In addition, the air chamber 4 divided in a possible embodiment into a plurality of sub-chambers, so that a partial damage to the outer wall 5 or the skirt leads only to a penetration of water into the respective sub-chambers. To prevent sinking of the air cushion model 1 can also buoyancy within the air chamber 4 or in the grooves 14 be provided. Furthermore, in one possible embodiment, the overpressure space 12 in turn divided into several chambers, a sinking of the hovercraft model 1 to prevent.

The inventive arrangement of the outer wall or the apron 5 offers a special ease of maintenance, ease of installation and a good seal.
