| 101 | Rail for chain saws | JP5978890 | 1990-03-09 | JPH02273201A | 1990-11-07 | HAINRITSUHI KESUPAA |
| PURPOSE: To perform a cutting work of a high cutting efficiency by a relatively small force by disposing a tip part of a rail so as to be positioned in one imaginary surface sector limited by an arcuate section having a specific radius. CONSTITUTION: A line for connecting a tip part S1 of a rail 21 from an end E1 of a forward-run in section 22 to a leg M1 of a perpendicular line 35 on a central axis 24 is indicated by a reference numeral 33. The leg M1 is equal to a central point of a cylindrical surface for forming an initial part of an inlet section 25, i.e., a central point of a circle having a radius of a line segment (M1-E1). An angle a1 formed between the line 33 and the axis 24 is 26'. A definite factor for operating the rail in no reaction depends upon this angle 1a. If the angle 1a is larger than this numeric value, it is completely held in non reaction. When an angle b1 formed between the axis and a tangential line 36 drawn along a point 37 disposed substantially at a center of the outlet section 30 is set to a value between about 40° and about 70°, a cutting efficiency at the time of cutting out can be particularly enhanced.

| PURPOSE:To facilitate the handling of a chain saw within a narrow operation area by providing a adjustment mechanism which is turned to adjust the chain saw for the setting position thereof through the turning axis of a driving wheel, between a chain saw guide member and a main frame. CONSTITUTION:When the driving source of a chain saw 22 is driven, the chain saw 22 engaged with a driving wheel is turned about a guide member 21. An adjustment mechanism A1 is put between the guide member 21 and when a turning frame 16 and a worm 25 is turned using a control button 26, a turning member 19 having a worm wheel part 23 is turned together with the guide member 21 through the axis of a driving wheel so that the chain saw 22 is adjusted for the setting position. Both the main frame 12 of a body frame 11 and a sub frame 13 containing the disk part of a turning frame 16 are joined and tightened with each other by the screw-up of a fixing ring 15 so that the turning frame 16 can be turned with respect to the sub frame 13, that is, the direction of the chain saw 22 can be changed to the horizontal or the vertical direction. Thus the chain saw may be improved for the operability in a narrow area. | ||||||

| PURPOSE:To simplify constitution by forming a concaved part for the free engagement with the tooth part of a chain sprocket onto the shoulder part of a cutting link having a cutting edge, thus omitting a driving link. CONSTITUTION:When a chain sprocket 7 is driven in the A direction, a saw chain 3 travels in the B direction, and when the preceding cutting edge 31R of a cutting link 15 bits into a member M to be cut, the link 15 tends to float-up in the C direction, but the shoulder part 23 contacts with the bottom part of guide groove 9, and since the pivotally supporting part for a side link 17 deflects to the edge 31R, 21L side, said floating-up is suppressed. Therefore, a driving link in the conventional saw chain can be cutting edge can be reduced furthermore. | ||||||
