| 20150118945 | HANDLE ARRANGEMENT FOR SANDER - An improved handle arrangement is provided for a power tool, such as a sander. The sander may include: a housing; a primary handle extending in a rearward direction away from an upper rear portion of the housing; a secondary handle positioned at an upper front portion of the housing, where the secondary handle is formed as a knob protruding in a forward direction which is opposite the rearward direction; a platen coupled to a lower portion of the housing; and a motor assembly disposed within the housing. A groove may be formed into an exterior surface of the housing along an intermediate portion of the housing, such that the intermediate portion extends between the primary handle and the secondary handle and the groove extends from a top surface of the housing towards a lower portion portion of the housing along opposing side surfaces of the housing. | 04-30-2015 |
| 20150314413 | HANDHELD ABRADING MACHINE - In order to provide a handheld abrading machine which has a simple, efficient and as fatigue-free an abrading action as possible and which includes a holding device for holding the abrading machine, a drive motor and a tool head, wherein the holding device includes a substantially tubular bar that has a proximal end and a distal end, wherein the drive motor is arranged at the proximal end, wherein the tool head is arranged at the distal end, wherein the abrading machine includes a transmission shaft which connects the drive motor to a tool holder of the tool head for transmitting torque thereto and which runs at least in sections thereof within the tubular bar, it is proposed that a motor shaft rotational axis of the drive motor be oriented transversely, and in particular inclined, relative to a longitudinal axis of the tubular bar. | 11-05-2015 |
| 20150367476 | SANDER, ESPECIALLY FOR SANDING CURVED SURFACES - A sander especially suited for sanding curved surfaces. The sander has an elongate body and a grinding plate movably attached thereto. A power unit drives the grinding plate. At least two lever beams are attached to the elongate body. Each of the lever beams has two opposite ends. The grinding plate is attached to ends of lever beams using flexible connecting elements to allow the grinding plate to move relative to the sander body. | 12-24-2015 |
| 20160039065 | Slug Retention Groove Forming Machine And Method - A portable and transportable die cavity modifying machine having a base carrying a carriage adjustable along one axis, e.g., a generally horizontal axis, and a machining head adjustable along another axis, e.g., a generally vertical axis, for modifying a die cavity of a stamping die in a manner that prevents blank or slug pulling during stamping press operation. The machine includes a grinder that can be pneumatically powered having a grinding bit used to precisely machine a slug retention groove in a die cavity defining surface (sidewall) of a die cavity formed in a stamping die. The machine has an angularly adjustable head carrying the grinder enabling adjustment of the angle of the groove relative to die cavity defining surface enabling the groove to be angled relative to the direction of a punch entering the die cavity during stamping. | 02-11-2016 |
| 20160121449 | PNEUMATIC GRINDING TOOL - A pneumatic grinding tool includes a rotatable shaft, a rotor, a sleeve, a bearing assembly, a fixing member, and an air feed assembly. The rotatable shaft includes a rotatable main body, a first connecting portion, a second connecting portion, and a clamping portion for clamping a grinding head. The bearing assembly is positioned between the sleeve and the rotatable shaft. The fixing member is connected to the second connecting portion. The air feed assembly includes a main body, an air inlet, and an air outlet. One end of the main body is sleeved on the sleeve, and the rotor is received in the main body. The main body, the sleeve, the bearing assembly and the rotatable shaft cooperatively form an air chamber configured such that when air flows into the air chamber, and the vanes of the rotor rotate, the rotatable shaft rotates with the rotor. | 05-05-2016 |
| 20160121475 | HAND HELD AND/OR HAND GUIDED POWER TOOL - A hand held and/or hand guided power tool comprising a housing with a motor and a working element performing an actuating movement if the tool is actuated. The motor is adapted to actuate a tool shaft in order to make it perform a rotational movement. A carrier element is functionally located between the tool shaft actuated by the motor and the working element for translating the rotational movement of the tool shaft into the actuating movement of the working element. In order to provide for a power tool, which allows perfect working of a workpiece with different types of actuating movements and/or working elements, it is suggested that the working element and the carrier element make part of a functional unit constituting a unit separate of the rest of the tool, wherein the functional unit is detachably fixed to the rest of the tool, in particular to the tool shaft. | 05-05-2016 |
