Claims
- 1. Hedging shears, comprising:
- a housing;
- drive means mounted to the housing;
- two cutting bars arranged parallel to each other, with at least one of said cutting bars being driven by said drive means to produce reciprocal movement between the cutting bars, and with both cutting bars being provided with opposed cutting teeth, defining cutting lines between adjacent pairs thereof, said driven cutting bar defining a leading end of the hedging shears as a function of the stroke generated by the reciprocal movement; and
- a plate-like guard element connected to the housing and extending parallel to the cutting bars and outwardly of the leading end of the hedging shears, said plate-like guard element being wider than the width of the cutting bars and having at its leading end a shoe-like shaped portion with a rounded leading skid face, the guard element further having rear flank faces at the rear side of the shoe-like shaped portion, said rear flank faces extending on both sides of the cutting bars and as far as the vicinity of a cutting line, said guard element comprising a guard cap defining a cavity which accommodates the leading cutting teeth of each movable cutting bar, wherein:
- one of said cutting bars is stationary; and
- the guard element is fastened to said stationary cutting bar.
- 2. Hedging shears, comprising:
- a housing;
- drive means mounted to the housing;
- two cutting bars arranged parallel to each other, with at least one or said cutting bars being driven by said drive means to produce reciprocal movement between the cutting bars, and with both cutting bars being provided with opposed cutting teeth, defining cutting lines between adjacent pairs thereof, said driven cutting bar defining a leading end of the hedging shears as a function of the stroke generated by the reciprocal movement;
- a plate-like guard element connected to the housing and extending parallel to the cutting bars and outwardly of the leading end of the hedging shears, said plate-like guard element being wider than the width of the cutting bars and having at its leading end a shoe-like spaced portion with a rounded leading skid face, the guard element further having rear flank faces at the rear side of the shoe-like shaped portion, said rear flank faces extending on both sides of the cutting bars and as far as the vicinity of a cutting line, said guard element comprising a guard cap defining a cavity which accommodated the leading cutting teeth of each movable cutting bar; and
- a fixed guide strip connected to the housing and associated with each cutting bar, wherein:
- each cutting bar is driven by said drive means; and
- the guard element is fastened to at least one of the guide strips.
- 3. The hedging shears as defined in claim 1, wherein said rear flank faces extend as far as the vicinity of the forwardmost cutting line of the cutting edges of forwardmost cutting teeth of the cutting bars.
- 4. The hedging shears as defined in claim 3, wherein the rear flank faces are obliquely inclined away from the leading end of the hedge shears thereby having the leading cut line free approximately to the bottom of the associated cutting teeth gap.
- 5. The hedging shears as defined in claim 4, wherein the rear flank faces have a concave shape.
- 6. The hedging shears as defined in claim 1, wherein the skid face is spaced from the leading end of the hedge shears such that a small gap exists when the leading end reaches its maximum displacement during the reciprocal movement.
- 7. The hedging shears as defined in claim 1, wherein the guard cap has a U-shaped cross section and an L-shape in longitudinal section with the cavity being open to the upper and lower side of the cutting bars.
- 8. The hedging shears as defined in claim 2, wherein the guard element includes an attachment lug extending parallel to and fastened to a guide strip.
