Definitions

  • This invention relates to mowing apparatus, and more particularly it is concerned with a mowing apparatus having an improved outlet opening for a cord serving as a cutter.
  • This invention has as its object the provision of a mowing apparatus of simple construction in which damage to the cord caused by the cord outlet opening can be minimized.
  • a mowing apparatus comprising a casing containing a cord and operative to rotate while an end portion of the cord is drawn out from the casing to outside, a slot having a major axis oriented in the direction of rotation of the casing is formed to serve as an outlet opening for drawing the cord therethrough from the casing to outside.
  • the constituent feature of the invention that the mowing apparatus is formed with a cord outlet opening in the form of a slot oriented in the direction of rotation of the casing as described hereinabove offers the advantage that the trouble of the cord being prematurely broken when it is drawn out through the opening of the circular shape of the prior art can be eliminated because the cord drawn out through the slot can be prevented from touching the edge of the slot as much as possible and the cord can be prevented from being bent at the same portion at all times even if a resistance of high magnitude is offered thereto.
  • FIG. 1 is a transverse sectional view of the casing of the mowing apparatus comprising one embodiment of the invention
  • FIG. 2 is a side view of the mowing apparatus shown in FIG. 1;
  • FIG. 3 is a view, on an enlarged scale, of a portion of the mowing apparatus shown in FIG. 1.
  • the mowing apparatus comprises a casing 1 of a substantially cylindrical configuration secured to a rotary shaft 2 for rotation counterclockwise about the shaft 2 when a mowing operation is performed.
  • a spool 3 which has a cord 4 of nylon as a cutter wound thereon in a plurality of windings.
  • the cord 4 is wound counterclockwise on the spool 3 and has an end portion drawn out from the casing in a certain length from a circumforentially elongated cord outlet opening 5 formed in a peripheral wall of the casing 1.
  • the opening 5 is in the form of a slot having its major axis oriented in the direction of rotation of the casing 1, i.e. it is elongated circumferentially and is short or narrow in height.
  • the edges of the slot 5 are smooth, i.e. uninterrupted by notches or the like.
  • the cord 4 moves between opposite ends of the major axis of the slot 5 depending on whether or not the cord 4 is in contact with grass.
  • FIGS. 1 and 3 show the manner in which the cord 4 behaves in the slot 5.
  • solid lines represent a cord 4 before coming into contact with the grass and dotted lines indicate the cord 4 in a position in which it finds itself immediately after cutting the grass.
  • a position A in which drawing out of the cord 4 from the spool 3 commences (FIG. 1) is close to one end B of the slot 5 which is a leading end of the slot 5 as seen in the direction of rotation of the casing 1 and remote from an opposite end C thereof.
  • portions of the cord 4 which are brought into contact with the ends B and C differ from each other.
  • the problem that the same portion of the cord is bent and twisted at all times with which the cord of the prior art was faced can be obviated, making it possible to prevent the cord from being prematurely damaged and broken.
