  • Patent number: 6887143
    Abstract: A power grinder, in particular an oscillating grinder (10), includes a platelike grinding sheet holder (14), on whose working face (15) a grinding sheet (16) can be braced. Secure clamping of the grinding sheet and easy changing of the grinding sheet are provided, because the grinding sheet (16) can be inserted between the clamping jaw (22) and the grinding sheet holder (14)—counter to the elastic prestressing of the clamping jaw (22)—and is firmly held increasingly strongly counter to the insertion direction in proportion to the tensile force engaging it.

  • Patent number: 6857948
    Abstract: A power grinder, in particular an oscillating grinder (10), having a housing (12) and a grinding sheet holder (14), on whose working face (15) a grinding sheet (16) to be received is braced, and its reception is effected by means of clamping means (20, 23) that lock opposite grinding sheet ends (17, 19) to the grinding sheet holder (14), is made easier to operate, and its machining capacity is improved, by providing that for equipping it with the grinding sheet, the clamping means (20, 23) are movable jointly with a grinding sheet end (17) clamped to them away from the opposite, likewise clamped grinding sheet end (19), so that the latter is locked, while under tensile stress.

  • Patent number: 6855041
    Abstract: An oscillating grinder (10) with a housing (12) a grinding sheet holder (14) having clamping means (20, 23; 200, 230; 334) for receiving a grinding sheet (16), whose grinding sheet ends (17, 19) can be clamped firmly to the grinding sheet holder (14), and in which the clamping means (20, 23; 200, 230; 334, 1334) are levers with a pivot axis (24; 224; 40; 440; 1440) supported on the grinding sheet holder side and clamping jaws (22; 220; 1222; 336, 338) that clamp the grinding sheet (16) on one end, preferably manually actuatable on the other end, can be equipped faster, more conveniently and more securely with a grinding sheet (16) by providing that one of the grinding sheet ends (19) for one-handed operation can be clamped solely by insertion between first clamping means (20, 23; 200, 230; 334; 1334), and the other grinding sheet end (17), likewise for one-handed operation, can be clamped after being placed in second clamping means (34; 334; 1334) and after their actuation; the grinding sheet (16) can be tens

  • Publication number: 20040033767
    Abstract: For a power grinder, in particular an oscillating grinder (10), with a platelike grinding sheet holder (14), on whose working face (15) a grinding sheet (16) can be braced whose grinding sheet ends (17, 19) can be held firmly on the grinding sheet holder (14) by means of clamping means (20, 23) disposed thereon, in which a lever with a pivot shaft (24) disposed on the top of the grinding sheet holder (14) acts as the clamping means (20, 23) and has a clamping jaw (22) on one end, braced on the grinding sheet holder (14), secure clamping of the grinding sheet and easy changing of the grinding sheet are possible by the provision that for equipping the power grinder (10), the grinding sheet (16) can be inserted between the clamping jaw (22) and the grinding sheet holder (14)—counter to the elastic prestressing of the clamping jaw (22)—and is firmly held increasingly strongly counter to the insertion direction in proportion to the tensile force engaging it.
