Definitions

  • Portable electric saws are of two general types: belt saws and circular saws.
  • a cutting process of a belt saw or a circular saw is unfavorably affected due to dim light in the operating environment.
  • an external illuminating device is additionally introduced to illuminate the cutting area of a portable electric saw, the cost will be increased. Further, if the external illuminating device is not properly positioned, a light support of the illuminating device will cast a shadow on a working table of the portable electric saw. Then, the cutting precision will be negatively affected and the operating efficiency will be reduced.
  • Cida Utility Model Patent No. CN201448686U published on July 9, 2009 discloses a belt saw comprising a plurality of illumination light bulbs 1 which are arranged in rows underneath a frame panel 3 of the belt saw. When a cutting process is performed, the plurality of illumination light bulbs 1 are switched on to illuminate a working table of the belt saw. A laser light source 2 is used to illuminate the cutting position so that a workpiece may be cut precisely.
  • the at least one illuminating device is an LED light.
  • Fig. 2 shows the portable electric saw 100 of the present invention which is provided with a fixed illuminating device at the other side wall.
  • a directional term “left” is defined as the direction in which the pivot shaft O is perpendicularly directed away from the paper surface of Fig. 2
  • a directional term “right” is defined as a direction opposite to the "left" direction.
  • the main portion 1 of the present portable electric saw 100 is provided with an adjustable device 6 for adjusting the illuminating area, as shown in Fig. 1.
  • the adjustable device 6 is attached to the guard 11 of the portable electric saw 100 so as to provide sufficient illumination for the cutting process, even after the inclination angle and the depth of the portable electric saw 100 and a position of the base plate 3 are adjusted and set.
  • the user can easily observe the cut area under various conditions, and the disadvantages in the prior art can be overcome.
  • the fixed illuminating device 5 is an illumination device secured or fixed to the guard 11 of the portable electric saw 100. Alternatively, the fixed illuminating device 5 is threadly connected to or is snapped in the guard 11.
  • the illumination range on the workpiece illuminated by the fixed illuminating device 5 corresponds to an A-B portion shown in Fig. 2.
  • the portable electric saw 100 comprises the adjustable device 6 and the fixed illuminating device 5, and the total illumination area equals the C-D portion and the C'-D' portion plus the A-B portion.
  • the illuminated area of the workpiece or the bottom plate is significantly increased, and the cutting operation can be facilitated.
  • the fixed illuminating device 5 may comprise a plurality of light sources, such as point light sources, which are located at the bottom end of the guard 11 and are arranged in rows.
  • the plurality of light sources arranged in rows can increase the illumination area of the fixed illuminating device 5, so that the user can observe the area of the workpiece to be cut more easily.
  • the adjustable device 6 or the fixed illuminating device 5 is electrically connected to a power supply of the portable electric saw 100 to be supplied with power by the power supply.
  • the adjustable device 6 and the fixed illuminating device 5 are powered by the power supply which powers the portable electric saw 100.
  • An additional power supply for the adjustable device 6 or the fixed illuminating device 5 may be omitted.

Abstract

Une scie électrique portative (100) comprend une partie principale (1), une lame de scie pour la coupe (4), une plaque de base (3) et un dispositif de sûreté (11) s'étendant depuis la partie principale (1) et recouvrant une partie de la lame de scie pour la coupe (4) qui se situe au-dessus de la plaque de base (3), la scie électrique portative étant dotée d'au moins un dispositif d'éclairage permettant d'éclairer une zone de la pièce devant être coupée, le(s) dispositif(s) d'éclairage comprenant un dispositif réglable (6) permettant de régler la zone d'éclairage. Avec la scie électrique portative, la pièce devant être coupée peut être bien éclairée quel que soit l'environnement lumineux externe pendant le processus de coupe. La précision de coupe et le rendement du travail de la scie électrique portative peuvent être améliorés.
