Definitions

  • a purpose of the present invention is to provide an improved guide frame, whose rise in temperature can easily be visually recognized and which is free from all the disadvantages described herein.
  • the guide frame of a chain saw around which an endless saw chain connected to a driving power source is guided, is fitted with a heat-sensitive colorant thereon.
  • a heat-sensitive colorant By watching the degree of color changes shown on the heat-sensitive colorant attached to the guide frame, harmful or dangerous temperature thereof can be easily detected.
  • FIG. 1 is a partial front view of the chain saw guide frame showing an embodiment of the present invention
  • FIG. 2 is another partial view of the chain saw guide frame showing another embodiment of the present invention and FIG. 3 is an enlarged cross-sectional view of the em bodiment along the line A A shown in FIG. 2.
  • an endless saw chain 2 is guided around a guide frame 1 while being driven by a chain-driving power source (not illustrated).
  • the guide frame 1 is fitted with a heat-sensitive colorant applied thereto either in a form of paint or a sticker at an appropriate place on the surface of the guide frame 1 by a painting or pasting process.
  • a guide frame 1 having a shallow concave region 4 formed, through the common manufacturing process thereof, at the nose part thereof may be caulked at 5 with proper caulking materials on which to fit the heat-sensitive colorant 3.
  • any unusual rise in the temperature of the guide frame 1 while in use causes the heat-sensitive colorant 3 to change its color. Therefore, as soon as the danger is detected by the chain saw operator who reads the color of the heat-sensitive colorant 3, appropriate steps can be taken to avoid damage to the chain saw.
  • the chain saw guide frame in accordance with the present invention can indicate its degree of heat accumulation with the changes in the color of the heatsensitive colorant, whereby it does not require any direct touch thereto by human body such as fingers for feeling out the heat and it can detect the extent of unsafe temperature visually, thereby contributing greatly to the safety in chain saw work.
  • the means of claim 1 further comprising a layer of caulking material interposed within said concave region between said colorant layer and said guide frame for retaining said colorant.
