Abstract: A shearing tool has a first unit with a first blade, rotatably coupled to a second unit with a second blade, at a first pivot having a first pin, so that displacement of the first blade relative to the first pin in a direction parallel with a first rotational axis is prevented, and the handle is connected to the second blade so that rotational movement of the handle relative to the second blade about a second rotational axis is allowed. The second rotational axis is defined by a second pivot interacting with the second blade and the handle at a distance from the first rotational axis in a direction away from a cutting edge contact point. When the shearing tool moves from an open to a closed position, the second blade is driven towards the first blade at the contact point for increasing the cutting capacity of the shearing tool.

Abstract: A hand operated shearing tool, comprising a first unit (1) comprising a first blade (11), the first blade (11) comprising a first cutting edge (112); and a second unit (2) comprising a second blade (21) and a second handle (22) connected to the second blade (21) at a proximal end (211) of the second blade (21), the second blade (21) comprising a second cutting edge (212), wherein the second unit (2) is connected rotatably to the first unit (1) about a first rotational axis (Ri) defined by a first pivot (3), the first pivot (3) comprising a first pin (31) penetrating the first blade (11) and the second blade (21); the first pin (31) is connected to the first blade (11) so that displacement of the first blade (11) in relation to the first pin (31) in a direction parallel with the first rotational axis (Ri) is prevented; the second handle (22) is connected to the second blade (21) so that rotational movement of the second handle (22) in relation to the second blade (21) about a second rotational axis (R2) is all

Abstract: The present invention relates to a stringed musical instrument comprising a hollow body with a top having a first opening or openings, a bottom and sides, one or more strings held in tension over said body, a bridge supporting the strings and positioned on the top adjacent the first opening or openings, a diaphragm resonator provided inside the hollow body and connected to the top below and surrounding the first opening or openings, and at least one second opening. According to the invention the bridge is suspended to the body and connected to the diaphragm resonator such that the vibration of the strings passes through the bridge to the diaphragm resonator.

Abstract: The present invention relates to scissor action tools which comprise first and second cutting elements pivotable about a first joint in a first plane of movement and first and second hand levers pivotable about a second joint in a second plane of movement. One end of the first cutting element is pivotally connected to one end of the first hand lever at a third joint and one end of the second cutting element is pivotally connected to one end of the second hand lever at a fourth joint, a line connecting the third and fourth joint forming a meeting line between the first and second plane of movement. The third and fourth joint allow the angle between the first and second plane of movement to be adjusted.

Abstract: A foot operated cutting device used to perform pruning, shearing, trimming, and similar operations includes a cutting head provided with a spring biased blade cooperating with a jaw, an actuating mechanism in a housing coupled to a foot actuating device. The foot operated cutting device generates power from a force input supplied by a user to the foot actuator.

Abstract: A lopper used to perform lopping, pruning and similar operations includes a lopping head provided with a spring-biased blade cooperating with a jaw, a drive mechanism, and an elongate housing. The drive mechanism includes first and second wheels rotatable relative thereto about a first axis. A head line couples the first wheel to the blade at a connecting point, and the second wheel is coupled to a driving line. The first wheel is eccentric relative to the second wheel so that a distance separating a region of a guiding surface of the first wheel from the first axis is smallest at a predetermined point of blade travel across the bight. The lopper also includes an intermediate handle and a lower handle selectively operable to actuate the blade relative to the jaw.

Abstract: A tool for performing lopping, pruning and similar operations includes a housing assembly formed of a pair of telescoping tubular sections. The tool also includes a tool head, a head line and an actuating line. The tool head, which is connected to one end of a tubular section, preferably includes a spring-biased blade coupled to the head line which is connected to a slidable block. The actuating line, while engaging the slidable block so that tensioning the actuating line causes movement of the blade, is also slidable relative to the block upon relative movement of the tubular sections.

Abstract: A hand tool for cutting, such as a pair of pruners, includes a pair of opposed elongated members, each member comprising a jaw at a front end portion thereof, a handle at a rear end portion thereof, and a midportion where the members cross over each other. A pivotable joint unites the midportions for scissor-like movement of the handles and jaws, and a spring biases the handles and jaws to an open position. According to the invention, one of the handles is rotatable. A transmission mechanism is provided to interconvert the rotation force applied to the rotatable handle into a rectilinear force used to draw the handles together.

Abstract: A variable force lopping tool is provided with a gear mechanism configured so that maximum leverage is obtained at a point in the cutting stroke corresponding to the maximum resistance by the workpiece being cut. The mechanism comprises a pair of mating gears formed on first and second elongated members and cooperating with a plate having a forwardly extending jaw or blade. The plate is pivotally connected to the first member. The second member is pivotally connected to a rearwardly extending tang of the plate.

Abstract: A fastening arrangement for plastics handles of scissors and equivalent in constructions in which the plastics handle is die-cast around a tang at the end of the blade-shaft. The tang has such a generally curved shape that on the outside of the blade-shaft there will be a rather thick plastics layer at the end of the tang, and, correspondingly, on the inside of the blade-shaft there will be a rather thick plastics layer at the root end of the tang.
