Definitions

  • the present utility model refers to an innovative constructive arrangement introduced in a wheelbarrow for the carriage of cargo.
  • the wheelbarrow is ancient equipment, developed by very remote civilizations, such as Egyptians, Greeks, and Chinese, to transport cargo and materials during wars and construction.
  • this tool has undergone changes in design and manufacturing materials, but has not changed in the functional mechanism.
  • the functional mechanism of most wheelbarrows is based on the concept of the second-degree lever (inter-resistant), where the load (resistive force) is arranged between the wheel axle and the handle (point of application of the potent force). In this case, to move the cart, it is necessary to apply a powerful force upwards, that is, lifting the cable.
  • Patent document BR 20 2014 0139007 U2 describes an arrangement applied to an open bucket wheelbarrow and a wheel, whose axle is located under and centrally to the bucket, so that the load is fully supported on the wheel.
  • the user to move the trolley the user must suspend the cable, setting the mechanism also with a second order lever, as it is necessary to make a powerful upward force to lift the load and move the trolley.
  • the present utility model stands out for its functional mechanism, which is based on the concept of the first degree lever (interfix) where the wheel axle (lever support) is positioned between the bucket (point of application of the load or resistant force) and the handles (point of application of the powerful force), reversing the dynamics of use of the equipment.
  • This new construction arrangement introduced in a wheelbarrow results in less force being applied to the transport of loads, greater travel stability, better maneuvering performance and ergonomic optimization for comfort, well-being and care for the user's health.
  • the user To move the cart, the user must apply a powerful downward force on the cart cable to lift the load.
  • the user For lifting the load and moving the trolley the user uses his own weight, considerably minimizing the applied efforts, providing a natural balance of balance and a rotational balance at the lever support point (wheel axle), ensuring that the trolley is shifted with less effort applied and better dynamic performance.
  • This mechanism reduces wear of the wearer, preserves the wearer from stresses directly submitted to the spine and enhancing his work performance.
  • the application of the first-order lever (seesaw) coupled with the fulcrum (wheel axle) that allows two-way rotational kinetics at the center of circumference and tangent of the tire makes the wheelbarrow perform well maneuvering in small spaces, while providing excellent balance inertia due to the counterweight the lever generates, offering greater stability, safety and comfort to the user.

Abstract

Un premier mode de réalisation structural de la brouette (fig. 2) comprend un bac (1) monté sur un châssis (2) et une roue (3). Le châssis (2) comprend deux branches latérales reliées à l'avant par un support d'appui (21) et de manière intermédiaire par un support de roue (32). L'extrémité arrière du châssis (2) présente un repose-mains (22) monté sur le bras du châssis (23). Entre le bac (1) et le repose-mains (22) se trouve la roue (3), laquelle est montée par palier sur un axe (31) monté sur le support de roue (32). Un deuxième mode de réalisation structural de cette brouette (fig. 9) comprend un bac (1) monté sur un châssis (2) et une roue (3). Le châssis (2) comprend deux branches latérales dont chacune est dotée d'un support d'appui (21) et d'un support de roue (32') où est montée l'une des extrémités de l'axe de roue (31). Les deux branches latérales du châssis (2) sont reliées par une traverse avant (25) et une traverse intermédiaire (26). Un troisième mode de réalisation structural de la brouette (fig. 10) comprend un bac (1) monté sur un châssis (2) et une roue (3). Le châssis (2) comprend deux branches latérales qui sont intégrées avec un support d'appui (21) et dotées d'un support de roue (32'') où est montée l'une des extrémités de l'axe de roue (31). Les deux branches latérales du châssis (2) sont reliées par une traverse avant (25) et une traverse intermédiaire (26).
