    摘要: The invention refers to a plate-like backing pad member (9) for use with a hand-held and hand-guided power tool (1). The backing pad member (9) is adapted for releasable attachment to a driving shaft (27) of the power tool (1) by means of a mechanical form fit connection arrangement comprising a protrusion member (16) connected to the driving shaft (27) and a recess member (17) connected to the backing pad member (9). The form fit connection is releasable in an axial direction running parallel to a rotational axis (13) of the backing pad member (9). The protrusion member (16) is held in the axial direction within the recess member (17) by means of an axial holding arrangement. It is suggested that the axial holding arrangement comprises at least one permanent magnet (40) on the one hand and at least one ferromagnetic element (41) or at least one further permanent magnet on the other hand exerting a magnetic force for holding the protrusion member (16) in the axial direction within the recess member (17). The at least one permanent magnet (40) or the at least one ferromagnetic element (41) or the at least one further permanent magnet is located in or makes part of the recess member (17).

    摘要: A hand-held, manually-operated sanding tool for use with a replaceable sheet-like abrasive material, such as sandpaper, includes a base member and one or more clamping mechanisms pivotally connected with opposed ends of the base member. The clamping mechanism(s) include a tensioning member arranged to slidably interface with a corresponding contact surface provided at the end of the base member to tighten the sheet-like abrasive material as it is installed on the tool. Further, the tensioning member positions a leading edge thereof so as to minimize possible harmful contact with a user's finger(s) during loading of the abrasive material.

    摘要: A clamping sander for receiving and holding a sheet of sandpaper, including a chassis plate having an upper surface and a lower surface, and a clamp plate having an upper surface and a lower surface. The clamp plate is coupled to the chassis plate and movable between a released position, spaced from the chassis plate, and a clamped position with the lower surface engaging the upper surface of the chassis plate. A clamping mechanism is carried by the chassis plate and the clamp plate for moving the clamp plate between the released position and the clamped position.

    摘要: A power sander includes a casing bounding a space in which a sanding plate is mounted for cyclical motion in parallelism with a plane of a support surface of the sanding plate. A sanding element, such as sandpaper, is supported on and covers the support surface of the sanding plate, and a clamping arrangement clamps the sanding element to the sanding plate. The clamping arrangement is mounted on the sanding plate for pivoting between an engaging and an disengaging position, and is biased toward the engaging position thereof. An actuating arrangement is mounted in a transverse wall of the casing for displacement between a retracted and an extended position and is operative for abutting against and displacing the clamping arrangement toward the disengaging position thereof during the movement of the actuating arrangement toward the extended position thereof. The actuating arrangement has an actuating portion which is accessible from the exterior of the casing, and a cam portion which engages an abutment surface of the clamping arrangement during the displacement of the actuating arrangement toward the extended position. The actuating arrangement may be arrested at least in the extended position thereof to thereby retain the clamping arrangement in the disengaged position during the exchange of the sanding element. Air may be withdrawn from the space bounded by the casing so as to remove dust resulting from the sanding operation from the vicinity of the sanding plate.

    摘要: An elongated rubbing shoe mounted for gyratory motion on a rubbing machine. To form the shoe, an elongated support is covered on its bottom and the top of one end portion with a layer of resiliently compressible material. A rubbing sheet underlies the layer, and one end of the sheet is anchored to the support by a clamp mounted on the top of one end portion of the support. A roller mounted on the top of the other end portion of the support is operable to pull the sheet tightly around the resilient layer and hold the sheet tensioned between the clamp and the roller. One end portion of the support is bent upwardly and the layer of resilient material is curved upwardly around that end portion and along the top of that portion. When the sheet is tensioned by the roller, the resilient material curving around the end portion of the support is radially compressed. As the sheet stretches in use, the resilient material expands to maintain the sheet tensioned between the clamp and the roller.

    摘要: A HOUSING MEMBER, WHICH SERVES AS A HANDLE FOR THE POWER SANDER, INCLUDES A DOWNWARDLY OPENING CAVITY HAVING A SUBSTANTIALLY CONTINUOUS TAPERED WALL SURFACE. A PNEUMATIC MOTOR IS RECEIVED WITHIN THIS CAVITY, THE MOTOR HOUSING OR FRAME DEFINING A SUBSTANTIALLY CONTINUOUS SURFACE IN SPACED, CONFRONTING AND COEXTENSIVE RELATION WITH THE TAPERED SURFACE. A RESILIENT SLEEVE OR BOOT HAS A FLANGE AT THE UPPER END THEREOF RECEIVED BETWEEN THESE SURFACES AND SECURELY WEDGED THEREBETWEEN BY FASTENING MEANS WHICH ENGAGE THE HOUSING MEMBER AND THE MOTOR HOUSING FOR DRAWING THE LATTER UP INTO THE CAVITY. THE LOWER END OF THIS RESILIENT SLEEVE IS CLAMPED TO THE RIGID BACKING PLATE OF THE SANDING PAD ASSEMBLY BY A PAIR OF RING MEMBERS, ONE OF THESE RING MEMBERS BEING SECURED TO THE RIGID BACKING PLATE. THE DRIVE SHAFT OF THE MOTOR MOUNTS ECCENTRIC MEANS WHICH ARE CONNECTED TO THE BACKING PLATE FOR IMPARTING ORBITAL VIBRATORY MOTION TO THE SANDING PAD ASSEMBLY UPON OPERATION OF THE MOTOR. OPPOSITE ENDS OF A SHEET OF SANDPAPER ARE SECURED TO THE SANDING PAD ASSEMBLY BY SPRING-BIASED CLAMPS, THESE CLAMPS BEING CONFIGURED AND ARRANGED SUCH THAT A PULLING FORCE ON THE SANDPAPER TENDS TO INCREASE THE CLAMPING FORCES.
