Definitions

  • the present invention relates to an electric portable chain saw.
  • Portable chain saws also known as chainsaws, are commonly used for pruning or forestry work such as felling, lopping and cutting trees.
  • the power source is constituted by a heat engine, which implies a relatively noisy and polluting operation.
  • Portable chainsaws are also known, the power source of which consists of a DC brushed electric motor or a brushed alternating current motor, with a power of between 400 Watts and 2500 Watts and whose operation is quieter and non-polluting. .
  • chain saws are provided with two carrying handles, and both because of the necessities (more or less important weight of the tools) than the habits of the person skilled in the art, one of these handles, usually referred to as the "front handle", is disposed above the engine block of the tool and the other generally referred to as the "rear handle” at the rear of the engine block or laterally to the engine block. last (when it is constituted by a counter-handle connected to the front handle), considering the positioning of the tool when making vertical cuts. This situation has the drawbacks of constantly occupying both hands of users and restrict the handling of these tools.
  • the present invention particularly relates to a portable electric chain saw to overcome the aforementioned drawbacks.
  • this objective is achieved by means of a portable electric DC power saw with a magnet rotor motor, of the "brushless” type and with electronic control and commutation, and whose carrying handle is arranged below the motor assembly including said DC electric motor, considering the position of the saw during a vertical cutting of wood, that is, the carrying handle is oriented perpendicularly or approximately perpendicular to the axis longitudinal guide bar, so that the saw can be held with one hand.
  • the carrying handle is disposed below the drive pinion meshing with the cutting chain.
  • the invention thus makes it possible to reduce the arduousness of the sawing work with the aid of a portable chain saw.
  • the trigger or on-off switch (and the safety trigger when the tool is equipped with such a security), controlling the start and stop of the power source, is (are) accessible on the handle of the chainsaw.
  • the pump ensuring the circulation of the lubricating liquid is housed in the handle of the tool, preferably in the lower part thereof.
  • the figure 1 represents a motor-driven portable chain saw of a current model consisting of an integrated compact device comprising a power source (heat engine or AC electric motor) enclosed in a casing C, a cutting device D comprising a chain teeth and a guide bar, and two carrying handles, a front handle PAV and a rear handle PAR, designed to hold and handle the tool with both hands.
  • a power source heat engine or AC electric motor
  • the power-driven portable chain saw comprises, in a conventional manner, a power source enclosed in a housing 1 and a cutting device comprising a chain with teeth 2 meshing with a driving pinion 7 and a guide-guide. chain 3 supporting and maintaining said chain.
  • the carrying handle 5 is disposed below the drive pinion 7 meshing with the toothed chain 2 ( figure 4 ).
  • the drive pinion 7 is mounted coaxially with the axis of the rotor of the motor 4.
  • the DC electric motor 4 may be capable of providing a power of between 600 Watts and 2500 Watts useful.
  • It may have a weight of less than 0.5 kg and, for example, a weight of less than 0.4 kg.
  • the motor 4 can have a weight of 0.3 kg and provide a power of 1200 Watts, the tool having a weight (all inclusive) of 1.880 kg.
  • the trigger or on-off switch 8A of the tool is accessible on the handle 5 and in front of it. It is, for example, mounted with a pivoting ability to the upper part of the handle 5.
  • the portable chain saws further include a system for lubricating the movable members of the tool, housed in the motor housing, which system comprises a reservoir for the lubricating liquid, usually oil, and a dispensing pump driven by a electric motor.
  • a system for lubricating the movable members of the tool housed in the motor housing, which system comprises a reservoir for the lubricating liquid, usually oil, and a dispensing pump driven by a electric motor.
  • the reservoir 9 containing the lubricating fluid of the tool can advantageously be placed in the casing 1, at the rear of the electric motor 4.
  • the pump 10 ensuring the distribution of the lubricating liquid contained in the reservoir 9, can advantageously be housed in the handle 5, below said reservoir 9, preferably in the lower part 5a of said handle, thanks to at this arrangement, the electric distributor pump 10 is constantly in a self-priming situation.
  • Control and management of the operation of the DC electric motor 4 and / or the lubrication pump 10 are provided by an electronic card.
  • this electronic control board is integrated in the carrying handle 5 of the saw.
  • control or control electronic card is integrated with the battery 13.
