摘要:
A hand-held device (10, 10′) for contactless distance measurement measures a distance (d) between a target object (18) and at least one reference point (20) of the device (10) using an emitted modulated measurement signal (16). The device includes a housing (12, 13, 56) with a first end (34) that faces the object (18) to be measured, and a second end (35) facing away from the object (18) to be measured. The housing includes an output unit (22, 28, 29, 31) for depicting measured results. Several measured distance values are to be assigned to at least one subsection of the path between the object (18) to be measured and the opposite end (35) of the housing (12, 13, 56) via a length-measurement scale (36, 38, 54) that is displayable in the output unit (22, 28, 29, 31).

摘要:
The invention relates to an electro-optical output unit (30, 31, 32, 130, 132) for representing measured distance values, especially an electro-optical output unit (30, 31, 32, 130, 132) for a hand-held length-measuring device. The invention is characterized in that the output unit (30, 31, 32, 130, 132) is adapted to represent a variable length meter scale (40, 52, 140) which changes with varying measuring distance of the device to a reference point of the distance measurement. The invention also relates to a measuring device, especially a hand-held distance measuring device, comprising said electro-optical output unit.
摘要:
The invention relates to a hand machine tool comprising a first housing shell (12, 150, 162), a second housing shell (16, 156, 168) different from the first housing shell (12, 150, 162) and being connected to the first housing shell (12, 150, 162) via a damping element (58, 60, 122, 132, 158, 170, 172), and a handle section (14, 152, 164) arranged on one of the housing shells (12, 150, 162). The invention is characterized in that the first housing shell (12, 150, 15 162) at least partially encloses the second housing shell (16, 156, 168).
摘要:
An electric hand power tool has a rotatable workshaft, a tool driveable by the rotatable work shaft and performing a movement selected from the group consisting of a rotary movement, a circulatory movement and an oscillating movement, an eccentric pin which is fixedly connected with the work shaft, a tool holder which receives the tool, a rotary bearing through which the tool holder is mounted on the eccentric pin, the eccentric pin and the rotary bearing being formed as an integrated component of the tool holder, and the tool holder being exchangeably coupleable with the work shaft.

摘要:
A portable power tool having a housing (12) and a tool (70), in particular a cutting tool, which is arranged thereon in such a way that it can be driven in a rotary and/or oscillating manner and which can be operated as prescribed by means of a suction-air flow, in particular with a dust extractor, is made especially robust and insensitive to clogging by chips by virtue of the fact that a turbine (36) having a rotatable turbine wheel (38) and a fixed turbine casing (60) serves as drive, wherein means (101) for the frictionless discharge/ejection of dust and chips that have entered the power tool inadvertently are arranged between the turbine wheel (38) and the turbine casing (60).
摘要:
The invention relates to a filter bag for filtering fine particles from a gas, having a filter coating at least of a certain coating thickness, and at least one filter layer of a certain layer thickness that disposed downstream of the filter coating in the direction of the gas flow. The invention is based on the task of providing a filter bag having a low tendency to clog, thus improving the service life of the dust filter bag, particularly upon the filtering of fine dusts. The task is solved in that the coating thickness of the filter coating (1) is essentially larger than the coating thickness of the filter layer (3, 4) disposed downstream.
摘要:
A portable drive unit (10) for operating a handheld power tool (70) by means of suction and/or blown air, is portable in an especially handy and space-saving way in that it has a housing (11), which is designed as a case (13) that is closable with a lid (24), and that its air feeding power is adapted to the power requirement of the handheld power tool (70), and it serves to store at least one such or similar handheld power tool (70), particularly with its accessories, such as air-carrying tubes and hoses.
