DESCRIPTION

ASSISTED WORK TRUCK

OBJECT OF THE INVENTION

The present invention refers to a manual work truck, with a series of advantages compared to conventional trucks of this type, such as the incorporation of pivoting wheels in the rear supports, a new and better grip, and incorporates brakes to control that do not move during loading, or on sloping floors.

The traditional manual wheelbarrow has a front wheel and rear legs, so that to move it you have to pry it and the user must lift and push it, with the effort and risk to your back that this entails.

It comes to solve the problem so far unresolved of facilitating the operator the handling and control of the load and its movement, in a much more comfortable way, without having to lift and carry the truck; presenting important benefits for the health of your back, getting much less tired and doing your job more safely.

The industrial application of this invention is within the field of the manufacture of trolleys, wheelbarrows and systems and hand-held transport devices, and more specifically, manual-powered wheelbarrow.

BACKGROUND OF THE INVENTION

Although no identical invention has been found to that described, we present below the documents found that reflect the state of the art related thereto.

Thus document EP0889818A refers to a load transport on the ground for waste or heavy objects that includes a platform frame and is inclined with the handle so that a trolley with wheels on pivoting support legs can tilt under the frame, to hold the load being transported. The load transport described is inclined, and does not include a complete support on wheels as proposed by the main invention, so the user always has to make a lever effort to keep the trolley in movement. With the solution of the main invention the displacement effort is minimal.

ES1045689U proposes an improved truck, consisting of a structure made up of two parts and angularly arranged, in one part of which two arms are incorporated for handling, while the other part is provided with steerable wheels, some trains being attached to the angular area wheels, which at the other end are joined by respective braces with respect to the beams of the structural part, remaining in an inclined position. In this case it is a wheelbarrow with two working positions of displacement, which implies that it is necessary to make a turn with the load to move from one to the other, while the main invention always works with the same position, and, in Consequently, there is no danger of spillage of liquid or other content that may fall or fall out of the container it has.

ES1129730U describes an improved trolley for the transport of materials, which comprises a chassis formed by three elements on each side, coinciding in its upper part on which the material collector rests, one of these elements being internally prolonged, the fixed support points of the trolley. and the rear lateral extension of the other element creates the trolley's drag handles. This wheelbarrow, unlike the one proposed by the main invention, does not include any means of support with wheels auxiliary to the main wheels, so that for its movement it is still necessary to make vertical effort on the part of the operator; problem that comes to solve the wheelbarrow of the main invention.

ES1054908U refers to an improved electric hand truck, for the transport of heavy loads, specially designed to go up and down stairs, improving the maneuverability and stability of the truck and driver's comfort, especially when driving on narrow stairs and in the turns of the stair landings, their operation by means of a reduction motor, and a phase variator, with an electrical outlet, housed inside the chassis and fixed on their corresponding supports, by means of connecting elements. This wheelbarrow departs from the patterns intended by the one proposed by the main invention, since it It is a cargo transport system designed to go up and down stairs. The main invention, for its part, solves movement and transport at the same level, as in the case of conventional trucks, but greatly improving comfort and control when doing so thanks to its pivoting wheels, grip and brakes.

Conclusions: As is clear from the research carried out, none of the documents found solves the problems posed as does the proposed invention.

DESCRIPTION OF THE INVENTION

The assisted work truck object of the present invention is constituted from a conventional manual work truck, with front wheel and rear supports, but at the base of said rear legs directional wheels with brakes are incorporated, facilitating the movement without need to lift the truck by hand, and with the safety of the brakes to prevent it from moving on an inclined surface, as if it had the traditional fixed supports.

As for the grip, in addition to having the handles or grip cuffs, it incorporates a horizontal bar at a higher height that joins the midpoints of both handles, further improving the comfort in the movement, being able to do this now by pulling by a single central point. The original handles are kept to facilitate the action of unloading the contents of the truck.

The brakes, on the other hand, can be provided directly on the wheels, operating them with the foot, or by means of handles incorporated in the grips or handles of the truck with their corresponding tension cables to the wheels.

DESCRIPTION OF A PREFERRED EMBODIMENT

A preferred embodiment of the assisted construction truck object of the present invention, with reference to the numerical references, can be based on a conventional manual construction truck (1), with front wheel and rear supports, comprising a set of steerable wheels ( 2) at the base of said rear supports.

These wheels (2) in turn have brakes (3) that can be operated directly with the operator's foot, which in a different embodiment can be controlled through handles (4) incorporated in the grips or handles of the truck with their corresponding tension cables to the wheels.

As for the grip, in addition to having the original grip grips, it incorporates a horizontal bar (5) at a height higher than these (about 90 centimeters from the ground), which connects the midpoints of both handles.

Claims (4)
