Abstract
Pruning shears or corresponding cutters comprising a first elongated handle part, a first blade part arranged as an extension of the first handle part, a second blade part pivoted to the first blade part from a first pivot point, and a second elongated handle part pivoted at its first end to the second blade part from a second pivot point. The second elongated handle part is connected to the first elongated handle part with at least one shaft pivotally connected to both the first and second elongated handle parts. The first and second elongated handle parts are arranged in the open position of the shears in remain along their entire length at a distance from each other enabling the use of the shears with one hand along the entire length of the handle parts.
Claims22
Pruning shears or other corresponding cutters comprising:
- a first elongated handle part having a first end and a second end,
- a first blade part arranged as an extension of the first handle part at its first end,
- a second blade part pivoted to the first blade part from a first pivot point for scissor-like movement relative to the first blade part between an open and closed position of the shears,
- a second elongated handle part having a first end and a second end pivoted at its first end to the second blade part from a second pivot point, and
- a first shaft pivotally connected to both the first and second elongated handle parts from points located closer to the second end than the first end of the elongated handle parts;
- a second shaft pivotally connected to both the first and the second handle parts from points that are closer to the first end of the elongated shafts than the pivot points of said at least one shaft:
- wherein the first and second elongated handle parts are arranged in the open position of the shears to remain along their entire length at a distance from each other that enables the use of the shears with one hand along the entire length of the handle parts.

A cutting device, comprising:
- a first handle having a first end and a second end;
- a second handle having a first end and a second end;
- a first blade member extending from the first end of the first handle;
- a second blade member having a blade portion and a lever portion, the lever portion pivotally coupled to the first end of the first handle and the first end of the second handle for movement of the blade portion in a shearing relationship with the first blade member between an open position and a closed position;
- and
- at least one shaft pivotally coupled to the first handle and the second handle;
- wherein the first handle comprises a trough portion configured to at least partially receive the second handle when the first blade member and the second blade member are in the closed position.

A pruner, comprising:
- a first handle having a first end and a second end;
- a second handle having a first end and a second end;
- a first blade member extending from the first end of the first handle;
- a second blade member having a blade portion and a lever portion, the lever portion pivotally coupled to the first handle and the second handle for movement of the blade portion in a shearing relationship with the first blade member between an open position and a closed position;
- and
- a first shaft pivotally interconnecting the first handle and the second handle to form a four-bar linkage with the lever portion so that the first handle and the second handle are substantially parallel when the first blade member and the second blade member are in the closed position and the first handle and the second handle are angled with respect to one another when the first blade member and the second blade member are in the open position.

- at least one shaft with which the second elongated handle part is connected to the first elongated handle part and which is pivotally connected to both the first and second elongated handle parts from points located closer to the second end than the first end of the elongated handle parts;
- wherein the first and second elongated handle parts are arranged in the open position of the shears to remain along their entire length at a distance from each other that enables the use of the shears with one hand along the entire length of the handle parts;
- and
- wherein the first and second handle parts are further interconnected with a second shaft pivotally connected to both the first and the second handle parts from points that are closer to the first end of the elongated shafts than the pivot points of said at least one shaft.
