Abstract

The invention relates to an amphibious all-terrain vehicle including a mechanism for lowering a person of limited mobility, an elderly person and/or an able-bodied person into water. The invention enables an able-bodied person or a person of limited mobility, seated on a cradle chair (5, Fig. 1), to move over difficult terrain and to have access to water sports and recreational facilities. The invention comprises four large wheels (2-3, Fig. 2) and a high-capacity, U-shaped float (1) which can support one or more people out of water and which is coupled to a lifting mechanism (10, Fig. 1) to facilitate the lowering of users into water. According to the invention, the user is protected from the weather by a removable roof (7, Fig. 1). The user can be moved over a body of water by means of two propulsion mechanisms (16 and 21, Fig. 2) which can be manually or electrically actuated depending on the person's disability.

Description

Amphibious all-terrain vehicle with launching aid mechanism for persons with reduced mobility, elderly and / or valid.

DESCRIPTION There are already different types of devices that transport people with reduced mobility and allow them to be in the water, but these types of devices have different disadvantages that our invention solves:

The person is always in contact with the water. No possibility of staying in the floating state without being in contact with the water.

Measurement of the seating surface.

Difficulty for a person with reduced mobility to get out or enter these types of devices when submerged in water. Stability of these types of equipment on the ground due to the fact that they are equipped with a single wheel at the front.

Stability of these types of devices in the water when the user is on them.

User protection in relation to climatic conditions. Moving in the water while being on these types of devices, using oars and / or shams.

The present invention proposes to solve, are the problems described above which we resume point by point below:

In the invention, the solution of this problem consists of an animated mechanism that allows the seat to go up and down. With this movement of the seat the user can be completely immersed or completely out of the water. In addition, the user can choose the level of immersion and / or the level out of the water. This lifting mechanism, maintained by two gussets, connected by a cable which is guided by a pulley. A seat in the transat style, allowing the user to put his legs horizontally, hooked by two levers to the back and two levers at the seat. The amphibious all-terrain vehicle is equipped with four wide low-pressure wheels, two of which are fixed at the rear and two directional at the front.

The buoyancy of the U-shaped amphibious all-terrain vehicle is sufficient to support the weight of an adult. The amphibious all-terrain vehicle has a roof provided with a protective cloth for the user protecting it from the weather conditions. The amphibious all-terrain vehicle has a propulsion system consisting of a crank followed by a transmission shaft coupled to gimbals to move a protected propeller. It can be of muscular or electric propulsion. According to the invention the amphibious all terrain vehicle, a user can access the beach and swimming with the intermediary of a person. Access to the beach is made easy thanks to the off-road concept and the help of a person. Access to bathing is made possible by the amphibious all-terrain vehicle following the concept for launch transfer assistance.

The main part is a large U-shaped float Figure 2 (1) made in one piece for intensive use in different materials stainless steel, pvc, polyester, carbon fiber. Its purpose is to support the weight of an adult person. On the float are assembled two parallel support bars for the ease of the user in the maneuvers out and back into the water. On the rear part of the float are two gusset paries Figure 2 (9), they will serve as an attachment point for fixing the manual lifting mechanism Figure 2 (10). At the top of the gussets are an axis containing a pulley Figure 2 (11) which serves as a guide for the pulling cable Figure 2 (12). This is actuated by the lifting mechanism Figure 2 (10). A roof figure 1 (7) removable composed of a frame provided with a protective cloth according to the climatic conditions for the user. In another particularly preferred embodiment of the invention, the float is composed of three parts. These will be coupled by a system of flanges and jobs for ease of transport and space saving. At both ends of the two floats are attached two stirrups, they will rely on the edge of the pool so they will serve stability when transferring the user to the all-terrain vehicle amphibious. Wheels large types and large diameter are all terrain, they are used as a damper for better comfort for the user. On the uniform ground, for example pool tiles, they will be small diameters. They are adapted to the float by a removable fastening system, two fixed wheels Figure 1 (2) at the rear of the float and two directional wheels Figure 1 (3) at the front of the float.

A chair type transat Figure 1 (5) allows the user to put his legs horizontally it allows to have a greater distance from the ground level. The transat type chair is designed with a tube frame on it is deposited a very thin perforated sheet. In another embodiment of the invention by it may be made of cloth, fabric, polyester. The backrest FIG. 1 (6) has a recline and removable armrests. At the back of the backrest, there are four gussets Figure 1 (9 -14) for fixing the removable lever arms Figure 1 (13). The four arms serve as a link between the chair and the float, their functions are to ensure a circular movement of 150 ° which allows to mount the chair of transat type out of the water or on the contrary to immerse completely and the user who took it. The user by this principle to choose the height of the water in immersion for a better exit in the water. The user will have no effort to perform to get out of the chair type transat or get back to it. This circular movement is due to the traction of the cable Figure 2 (12), it is attached to the lower part of the backrest by the lifting mechanism Figure 2 (10), actuated by the user himself or by a person valid. The pulling force on the cable is provided by the manual lift mechanism 2 (10). In a second mode of operation this traction force is provided by an electrical system (an electric jack).

The traction of the amphibious vehicle all terrain is done by a cord or a rigid bar fixed at the anchoring point figure 2 (4). Manual propulsion system:

A crank Figure 2 (16) located at shoulder height of the user coupled to a transmission shaft Figure 2 (22). This transmission bar is fixed to multiplier boxes Figure 2 (19) and through corner joints Figure 2 (16 - 19) this rotary movement is transmitted to the propeller. The propeller Figure 2 (21) is protected by a perforated plate (guarantor) Figure 2 (20). Electric propulsion system.

An electric battery provides energy to an electric motor, this electric motor provides rotational movement to the propeller. A control box allows the starting of this engine or the starting in both directions movements of the propeller on the left, movements of the propeller on the right.

Concerns the movement on the water of the amphibious all-terrain vehicle by oars or oars which would be positioned figure 1 (8) or removable. Concerns the displacement on the water of the amphibious all terrain vehicle thanks to a sail by removable addition or not.

In another embodiment of the invention which consists in creating an amphibious all-terrain vehicle of two to several places.
