Abstract
A hand power tool has a housing; at least one handle having at least one gripping part; at least one elastic, vibration-damping element; a mounting part mounted on the elastic element; the gripping part being mounted on the housing through the elastic element and through the mounting element; and at least one movable safety element through which the gripping part is connected with the mounting part.
Claims8
A hand power tool, comprising a housing;
- at least one handle having at least one gripping part and a mounting part;
- at least one elastic, vibration damping element mounted on said mounting part, said at least one gripping part being mounted on said housing through said elastic element and through said mounting part;
- and at least one safety element through which said gripping part is connected with said mounting part, said safety element being formed as a rigid component movable during a predetermined operation relative to said gripping part in at least a tilting direction and a longitudinal direction to avoid a passage of vibrations through the safety element;
- and further comprising sleeves mounted on said mounting part and on said gripping part correspondingly and provided, with discs, said safety element being arranged at the distance to said sleeves and said discs, which distance is filled with an elastic material.

A hand power tool, comprising a housing;
- at least one handle having at least one gripping part and a mounting part;
- at least one elastic, vibration damping element mounted on said mounting part, said at least one gripping part being mounted on said housing through said elastic element and through said mounting part;
- and at least one safety element through which said gripping part is connected with said mounting part, said safety element being formed as a rigid component movable during a predetermined operation relative to said gripping part in at least a tilting direction and a longitudinal direction to avoid a passage of vibrations through the safety element;
- and two sleeves mounted on said mounting part and on said gripping part correspondingly and provided with two discs, such that said sleeves and said discs correspondingly limit chambers, said safety element being formed as a rod having two ends provided with further discs, said further discs being non-releasably held in said chambers.
1 more element
A hand power tool, comprising a housing;
- at least one handle having at least one gripping part and a mounting part;
- at least one elastic, vibration damping element mounted on said mounting part, said at least one gripping part being mounted on said housing by said elastic element and by said mounting part;
- and at least one safety element which is provided for connecting said gripping part with said mounting part, said safety element being formed as a rigid component movable during a predetermined working operation of said hand power tool relative to said gripping part in at least a tilting direction and a longitudinal direction to avoid a passage of vibrations through the safety element, wherein said elastic element has a first end and a second end located opposite to said first end, and said safety element extends at least from said first end of said elastic element to said second end of said elastic element which is located opposite to said first end of said elastic element.
A hand power tool, comprising a housing;
- at least one handle having at least one gripping part and a mounting part;
- at least one elastic, vibration damping element mounted on said mounting part, said at least one gripping part being mounted on said housing by said elastic element and by said mounting part;
- and at least one safety element which is a part of a fastening, which is provided for fixing said elastic element to said mounting part, said safety element being formed as a rigid component movable during a predetermined working operation of said hand power tool relative to said gripping part in at least a tilting direction and a longitudinal direction to avoid a passage of vibrations through the safety element, wherein said elastic element has a first end and a second end located opposite to said first end, and said safety element extends at least from said first end of said elastic element to said second end of said elastic element which is located opposite to said first end of said elastic element.
