  • Publication number: 20130140051
    Abstract: A hand-guided apparatus may include an operating lever, a switch, and an intermediate lever. The operating lever may actuate a function of the hand-guided apparatus, be constructed in an elongated manner and be pivotably attached to a housing of the apparatus. The switch actuates the function and is arranged in the housing. The intermediate lever mechanically actuates the switch. The operating lever includes a safety element enabled to be pretensioned and shifted along a longitudinal axis of the operating lever. The operating lever and the intermediate lever are enabled to be mechanically coupled by shifting the safety element into a pretensioned state to enable actuation of the switch by pivoting of the operating lever. The operating lever and the intermediate lever are enabled to be mechanically decoupled by shifting the safety element into a relaxed state to prevent actuation of the switch by pivoting of the operating lever.

  • Publication number: 20130020102
    Abstract: A typically battery-operated power tool, such as a chainsaw or hedge trimmer, comprising a working element (4), a motor (6) arranged to drive the working element (4) and a controller (9) arranged to control the speed at which the motor drives the working element (4), in which there is provided a sensor (12) for at least one factor indicative of the efficiency with which the power tool is being operated, the controller (9) being arranged to vary the speed at which the motor (6) drives the working element (4) should the factor indicate that the power tool is being operated in a sub-optimal manner. Typically, the factor is the pressure which the user is applying the power tool, and the sensor (12) is a sensor for the current flowing through the motor (6).

  • Publication number: 20130008563
    Abstract: For hand-operated garden shears, in particular tree-pruning shears, with a ratchet mechanism, it is proposed that, between a hand lever (H2) and a scissor lever (H1) between which a ratchet lever (RH) can engage in different latching positions according to the ratchet mechanism, there is also provided, in addition, a preferably rotatable abutment surface (AF) on the hand lever (H2) and a mating bearing surface (GF) on the lever extension, or vice versa, which, at the end of an initial closing operation with the ratchet lever (RH) in a first ratchet position, allow a continuation of the cutting operation as a direct cut without further use of the ratchet mechanism.

  • Publication number: 20120167741
    Abstract: A blade for a hedge trimmer comprises a plurality of cutting teeth, each tooth having a longitudinal axis extending laterally away from the long axis of the blade, each cutting tooth comprising a root and a tip and opposing sides extending between the root and the tip, characterised in that at least one of the cutting teeth comprises a special tooth which is sharpened along at least one flank to form a cutting edge which extends to the free end of the tooth, and further in which the free end of the special tooth includes a connecting edge which extends from one flank of the tooth to the other and at least one part of which is inclined at an angle of between 4 degrees and 20 degrees relative to the long axis of the blade.

  • Publication number: 20120167394
    Abstract: The invention relates to a motor-driven cutting device with a double blade arrangement driven by means of a double eccentric arrangement having opposing oscillating blade movement, comprising an advantageous construction with a separate double eccentric group for the drive device that can form a uniformly operable front-part group, particularly in conjunction with the double blade arrangement at a particularly favourable cost, and that is advantageous for installing the front-part group in the production process and/or when replacing the preferably uniformly operable front-part group.

  • Publication number: 20120167395
    Abstract: A blade 1 for a hedge trimmer having a long axis and comprising a plurality of cutting teeth, each tooth having a longitudinal axis extending laterally away from the long axis of the blade 1, each cutting tooth comprising a root and a tip and opposing sides extending between the root and the tip, characterised in that at least one of the cutting teeth comprises a special tooth which is sharpened along at least one side to form a cutting edge, in which a first portion of the cutting edge is bevelled such that a tangent line to the first portion is inclined at an angle of between 1 degrees and 6 degrees relative to the longitudinal axis of the tooth, and a second portion of the cutting edge closer to the tip of the tooth than the first portion and which is bevelled such that a tangent line to the second portion is inclined at an angle relative to the longitudinal axis of the tooth of between 8 degrees and 25 degrees.

  • Publication number: 20120047750
    Abstract: For manually actuated shears with a ratchet mechanism it is proposed to provide an additional locking member that circumvents the ratchet mechanism and enables the operation of the shears in a direct cut mode in which a single closing process of the handle levers also causes complete closing of the blade arrangement.

  • Publication number: 20110226871
    Abstract: The invention relates to the mechanical inversion of direction of a rotating control component of a landscape sprinkler device. Such a device, having a switching member with end stops associated therewith in both pivoting directions the control component, against said stops the switching member stops and is actuated, wherein at least one end stop can be adjusted coaxially with respect to a pivoting axis of the control component. According to the invention the switching member is configured in an elastically resilient manner on the contact region (6) thereof that is positioned at the height of the end stops (10, 11) such that the contact region retreats back from the adjusting path of the end stop in case of an overload, and means (14) are provided in order to re-establish the contact region at a defined position in the rotation angle region between the two end slops from the retreated position.

  • Publication number: 20060076152
    Abstract: A soil cultivation appliance, especially a lawnmower, which can be motor-driven or manually driven. The appliance is provided with a steering shaft and a steering frame or wheel for the operator. The steering device enables the soil cultivation appliance to change direction due to the fact that torque is introduced into the housing of the soil cultivation appliance by the steering shaft. The torque is used to change the direction of the advancing movement, to the left or to the right, without needing to steer the wheels. An advantage of the appliance is that, when the steering shaft is arranged on the housing in a continuously pivotable manner, the position of the operator is independent from a thrust frame or the like, by which means the soil cultivation appliance must be mechanically guided.

  • Patent number: 7021669
    Abstract: A coupling part for a fluid coupling device, especially a hose coupling, which has a looking device switchable between two positions. The locking device has locking elements mounted on a base body, and a socket-shaped actuating element that interacts with the locking elements. The coupling part is switchable between a retaining and releasing positions by an axial releasing movement of the actuating element. In the retaining position, the locking elements hold the counterpart of the coupling, e.g. a hose stem, to prevents it from being pulled out and, in the releasing position, the locking elements release the same in order to disengage the coupling. The actuating element can be moved from the retaining position into a locking position, prohibiting a releasing movement, by rotating the actuating element in a limited manner around the longitudinal axis of the coupling. As a result, the coupling is prevented from being unintentionally disengaged.
