173018000 | DRIVE CONTROLLED BY RELATIVE MOVEMENT OF ADVANCE CAUSING OR CONTROLLING MEANS OR MANIPULATING HANDLE | 13 |
20090008111 | Vibrating hand-held power tool with a locking switch for a motor switch - A rotary-percussion hand-held power tool includes a vibrating percussion mechanism ( | 01-08-2009 |
20090056965 | Vibrating hand-held power tool with a locking switch for the motor switch - A rotary-percussion hand-held power tool capable of applying blows along a percussion axis (A) includes a percussion mechanism assembly ( | 03-05-2009 |
20110042114 | POWER TOOL WITH IMPROVED START ACTUATOR - A power tool system includes a two-handed power tool having first and second start actuators, one for each hand of an operator. A controller prevents the power tool from initiating an operating cycle unless both actuators are turned ON to reduce the possibility of the operator's hands being disposed in a hazardous position during operation of the power tool. To discourage manual override of the dual-start-switch system, the controller prevents the power tool from initiating an additional operating cycle until both actuators have been switched OFF and then ON again. The second actuator includes a tubular sleeve that extends over part of the power tool to allow the sleeve to slide axially relative to the power tool between ON and OFF positions. Axial movement of the sleeve from its OFF position to its ON position turns ON the second start actuator. | 02-24-2011 |
20110180285 | IMPLEMENT HAVING AN OVERRUNNING CLUTCH - An implement having a drive, a drive element that may be driven by the drive and that is disposed in an axially moveable manner and is coupled to the drive element, and an overrunning clutch disposed in the drive or in a torque flux between the drive and the drive piston. If the drive has a movement that is slower than that of the drive element, the overrunning clutch is in an idle state, in which the clutch interrupts the torque flux between the drive and the drive element, thus decoupling the movement of the drive element from the drive torque of the drive. In this manner, the drive element may move more rapidly, for example during the return movement thereof, than would correspond to the movement forced by the drive. | 07-28-2011 |
20120118594 | EXTENSION POLE WITH DOCKING ASSEMBLY FOR A MATCHING TOOL - An extension pole having a tool-actuating connection between a lever on the pole handle end and a tool on the pole distal end that remains operational by action of a lever on the pole proximal end through pole adjustment. A quick release mechanism on the pole distal end receives a tool matching that mechanism through which the movement of the lever is communicated to the tool causing the tool to operate in its normal function. | 05-17-2012 |
20120222877 | HAND TOOL TELEACTUATING POLE CONTROLLED BY A THRUST TOWARDS THE SUPPORT MATERIAL - The pole comprises a securing end, with tool securing means and tool actuating means, a gripping end to be gripped by an operator, and telecontrolling means for telecontrolling the actuating means. The actuating means are arranged in the tool securing means to be directly controlled by the pole securing end and thus telecontrolled by the pole and its gripping end under the action of a thrust of the pole towards the support material. The pole is well adapted to sealing guns. | 09-06-2012 |
20120292063 | ELECTRONIC SWITCHING MODULE FOR A POWER TOOL - An electronic power apparatus includes a housing, a pair of input power pins, a pair of output power pins, power components arranged to modulate a supply of power from the input power pins to the output power pins, and a user-actuated input unit providing an analog signal indicative of a desired power output level of the output power pins. A control unit of the electronic power apparatus receives the analog signal from the user-actuated input unit. The control unit includes a controller to control a switching operation of the power components based on the analog signal, and an input detection unit to generate an ON/OFF signal to turn on the controller based detection of a prescribed change in the analog signal indicative of an initial actuation of the user-actuation unit. | 11-22-2012 |
20130092409 | Hand-Held Power Tool with Mechanically Controlled Automatic On and Off Function - A hand-held power tool includes a tool housing and a handle housing. The handle housing is movable relative to the tool housing. The hand-held power tool also includes an electric motor for driving the hand-held power tool. The electric motor is switched on and off by a relative movement of the handle housing relative to the tool housing. The hand-held power tool also includes a main electrical switch configured to apply an electrical voltage supply to the electric motor. The main electrical switch is switched by an actuating mechanism. The main electrical switch is actuatable with the aid of a movable component that is movable relative to the tool housing handily via the actuating mechanism, either directly or by the actuating mechanism. | 04-18-2013 |
20130133906 | TACKER - A tacker includes a first arm pivotably connected to the body by a first pin and a second arm is pivotably connected to the body by a second pin. The first end of the second arm is movable along the underside of the first arm. A shaft is connected to the second end of the second arm and between two hook plates which are detachably hooked to a resilient plate which is connected with a push plate. The first arm is pivoted downward about the first pin while the second arm is pushed by the first arm and pivoted about the second pin. The hook plates lift the resilient plate, and are then disengaged from the resilient plate to release the push plate to eject staples. The first and second arms respectively perform two different leverage actions to save the users' efforts. | 05-30-2013 |
20130140051 | HAND-GUIDED APPARATUS WITH AN OPERATING LEVER - 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. | 06-06-2013 |
20130248216 | POWER TOOL - A power tool comprising a hollow pole, a prime mover disposed at one end of the pole, a tool disposed at the other end of the pole, a transmission shaft rotatably disposed within the pole and configured to transmit torque from the prime mover to the tool, a joint mechanism configured to support the tool such that the tool is capable of rotating with respect to the pole, a lock mechanism configured to selectively lock and unlock the joint mechanism, and a clutch mechanism disposed on a pathway of torque transmission from the prime mover to the tool via the transmission shaft, and configured to selectively connect and disconnect the pathway of torque transmission. The lock and clutch mechanisms are coupled with each other such that the clutch mechanism disconnects the pathway of torque transmission when the lock mechanism unlocks the joint mechanism. | 09-26-2013 |
20140131058 | LOCKOUT MECHANISM - A power tool including a power base and a tool head. The power base includes a trigger and a motor such that the trigger actuatable to drive the motor. The tool head is driven by the motor, and includes a lockout mechanism that inhibits actuation of the trigger in a locked. The lockout mechanism is manually rotatable from the locked position to an unlocked position in which the trigger is actuatable to drive the motor. | 05-15-2014 |
