Description

DESCRIPTIVE MEMORANDUM TITLE AND TECHNICAL FIELD OF THE INVENTION The object of the present invention refers to a BOAT TRANSPORT CART that has a functional design that allows it to be stored, transported and used in a simple and convenient way, the field of the invention being related to products that facilitate the transport of boats (kayaks, rowing boats, small training sailboats, canoes and others), whether for the sea, rivers or lakes. STATE OF THE ART AND BACKGROUND OF THE INVENTION Currently there are several types of carts that allow the transport of small boats and generally consist of two wheels that are arranged at the ends of a single axle from which two elongated supports of short length protrude, acting as beds on which the boat to be transported rests, in such a way that it needs to be held by means of ropes or traction straps so that both function as a single piece. There are also kayak transport devices that fit into the drain scuppers (open or self-bailing kayaks (sit-on-top) have holes through which any water that may enter drains, called drain scuppers), supporting the entire weight of the boat, which can cause them to deteriorate and, as a result, affect the buoyancy of the kayak. PROBLEMS TO BE SOLVED BY THE PRESENT INVENTION The present invention, a BOAT TRANSPORT CART, is a device that facilitates the transport of a boat with the following advantages over similar existing devices: 1994987 of 8 1- The kayak is secured to the cart by the lever action between them, and the weight of the boat exerts the necessary force on the device to ensure that it is properly secured for transport. 2- It loads quickly since no time is wasted tying it up. 3- You can travel on paths with various obstacles such as steps, stones, curbs, pits and so on, without risk of the fastening loosening. 4- There is no risk of damaging the scuppers. The cart makes contact with the rope at the bottom of the kayak and with the upper crossbar, which has protective supports, at the top. BRIEF DESCRIPTION OF THE INVENTION The present invention, a BOAT TRANSPORT CART, is a device that facilitates the transport of a boat and consists of a tubular structure that has two side wheels located at the lower outer ends of the side tubes, a rope on which the boat rests and which is attached at its ends to the side tubes by pressing the boat on the upper crossbar that joins the side tubes.

DETAILED DESCRIPTION OF THE INVENTION The BOAT TRANSPORT CART is a device used to facilitate the transport of boats such as kayaks, canoes, and any other small boats. It consists of an inverted U-shaped tubular body with a square or cylindrical cross-section, divided into four interlocking parts (1, 1', 1'', and 1'''). Each lower end of the cart has a wheel (2 and 2') on the outer side, facing each other, with their axles located on the same imaginary axis. The lower section of each side of the cart (1 and 1''') Section 1994987 of 8 features a short axle perpendicular to the tubular body, extending outwards, into which the corresponding wheel is inserted (2 and 2'). Near its upper end, on the outer side, it has a short T-shaped stem (7 and 7'), and at its upper end, a short continuation of its tubular body, of smaller diameter or profile, which will fit into the lower end of the tubular body of the upper section (1' and 1''). Each upper section (one on each side - 1' and 1'') has its upper end curved at 90 degrees towards the center of the structure, while the lower part of these sections is curved in a smooth "S" shape forwards, with a short T-shaped stem (6 and 6') near its lower end on the outer side. These upper sections, at their upper curve towards the center, have a tubular elastic protector located outside the tubular body (4 and 4'), enveloping it.Since one of the upper sections has at its upper horizontal end a short continuation of its tubular body, of smaller diameter or profile, which will be fitted into the upper horizontal end of the tubular body of the other upper section, fixing them with the upper adjuster (5). Once assembled, with all its sections properly fitted and secured, a rope or cord (3) is placed in the inner middle section, the ends of which (3' and 3'') are wound and secured using the T-shaped rods (6, 6', 7 and 7') on each side of the tubular body. This will also secure the fit between the lower and upper sections. The procedure for use is as follows: the upper sections (1' and 1'') are placed on the kayak, fitting them together and securing them to the desired width using the upper adjuster (5). Then, each of the lower sections (1 and 1'') is fitted into the lower end of the upper sections (1' and 1''), so that the wheels (2 and 2') face outwards and the "S" bend of the upper sections (1' and 1'') faces forward. Next, the rope (3) is attached, winding it around and securing its ends (3' and 3'') to the tubular body at the corresponding side pins (6, 6', 7, and 7'). Finally, the stern of the boat is grasped and passed through. 1994987 of 8 between the rope (3) and the upper horizontal ends, proceeding to give it an up and down movement to make the cart run freely by gravity towards the central part of the kayak until it is positioned in the desired position, so that the wheels (2 and 2') are at the back and the top of the cart is at the front so that it is inclined in the correct way.The kayak will then be taken by the bow and lifted, allowing the kayak to rest on the rope. This will cause the wheels (2 and 2') to grip the ground and support the entire weight of the kayak, making the upper horizontal end of the cart rest and exert pressure on the top of the kayak. The rope (3) will then be centered, causing the cart to be secured to the kayak by the action of the aforementioned forces (the kayak is trapped between the rope (3) and the upper crossbar formed by the upper ends of the upper sections (1' and 1'')), thus allowing it to be transported comfortably and safely. This device, as explained, bases its operation on the use of 3 support points, one is the rope (3) that transmits the force exerted by the weight of the boat to the middle part of the side sections of the cart which will transmit it to the ground on which the wheels (2 and 2') rest and to the upper horizontal end of the cart causing it to exert downward pressure on the top of the boat, which manages to secure the cart to the structure of the boat leaving the wheels in a rear position with respect to the rest of its structure, allowing the assembly to move forward without problems. For better understanding, three moments of the process of positioning the cart (8) to transport a kayak (9) are represented in Fig. 4, Fig. 5, and Fig. 6, viewed from a side perspective. The three support points are labeled 12 (lower support point, on the ground (11)), 13 (middle support point, related to the rope (3) that supports the weight of the kayak (9)), and 14 (upper support point, related to 1994987 of 8 the upper crossbar of the trolley (8) that rests on the kayak (9)). In Fig. 4 the stern of the kayak (9) has been inserted under the upper crossbar of the trolley (8), without touching it, resting it on the rope (3), in such a way that the lower support point (12) is delayed with respect to the forward position of the upper support point (14) to facilitate the positioning of the trolley (8). In Fig. 5 the trolley (8) is already in a more forward position, whereas in Fig.6 is already positioned at a point where the upper support point (14) is supported against the upper surface of the kayak (9), the middle support point (13) is in a rearward position and the lower support point (12) is in an even further rearward position with respect to the other two support points, which causes the cart to be tilted forward and fixed in that position thanks to the action of the forces acting on said 3 support points: the floor exerts an upward force on the lower support point (12), the weight of the kayak (9) exerts a downward force on the middle support point (13), which causes the upper support point (14) to exert a downward force on the upper surface of the kayak (9) due to the positions of the other two support points and the action of the aforementioned acting forces, managing to fix the cart (8) to the kayak (9) without the need for any other element.Therefore, to remove the cart (8), simply rest the bow of the kayak on some fixed element or on the ground, lift the stern a little and remove the cart (8) by moving it backwards. It is logical to assume that when this invention is put into practice, modifications may be introduced with regard to applications, without departing from the fundamental principles that are clearly specified in the claims clauses that follow.-----------------------------------------------7 1994987 of 8 CARLOS ALBERTO CARBALLO - 20149007572 Digitally signed by PORTALTRAMITES - INPI Date: 2022.10.11 19:12:31 -03:00 Reason: Digitally Signed by the INPI Location: Buenos Aires, Argentina 1994987
