Abstract: A device for supporting at least one arm of a user, has one or more arm support elements, each of which has an arm shell for mounting on an arm. Passive actua-tor(s) are configured to exert a force on an arm support element by way of which an upward movement of the arm in the arm shell is supported when the device is in the mounted state. The device includes at least one counter bearing for the force to be applied, and at least one actuating element, the actuation of which allows the actuator to be moved into a first state where the actuator exerts the force on the at least one arm support element, and into a second state in which it exerts a smaller or no force on the arm support element.

Abstract: A device for receiving a hand-held power tool is provided. The device can serve as an interface between the hand-held power tool and a support or carrying structure and comprises a first and a second fastening means and a counter structure. With the interface it is possible to optimally adapt the suspension of the hand-held power tool to the center of gravity of the hand-held power tool. In addition, the interface can be adapted to different hand-held power tools or types of hand-held power tools by an adjustable distance between the first fastening means and the counter structure or an adjustable diameter of the counter structure. In further aspects, the invention relates to the use of the interface for fastening a hand-held power tool to a support structure, and to a corresponding method.

Abstract: A system for counterbalancing a weight force of an object is provided. The object is fastenable to a traction cable, wherein the traction cable is guided in or on a cantilever in the direction of a back structure of the system, wherein a second end of the cantilever can be accommodated by a back structure, and the system can be carried by a user of the system via the back structure. The system is characterized by an electronic module which includes an apparatus for winding up the traction cable and a motor for driving the apparatus for winding up the traction cable, wherein the system is configured to determine a counterforce for the weight force of the object and to transmit same to the object. It is particularly preferred for the purposes of the invention that a control device of the system is configured to adjust a counterforce with respect to the weight force of the object.

Abstract: A handle for a power tool, wherein the handle has a switch-on lock and an operating switch. The handle is characterized in that the switch-on lock is configured to prevent contact between a spring element of the operating switch and an electronic switching element in a blocking position of the switch-on lock and to permit same in an operating position of the switch-on lock. In a second aspect, the invention relates to a power tool having a handle. In further aspects, the invention relates to methods for switching on a power tool and for switching off and locking a power tool, wherein contact between the operating switch and an electronic switching element can be prevented in a blocking position and permitted in an operating position.

Abstract: A handle for a power tool, wherein the handle has a safety switch and an operating switch. The handle is characterized in that the safety switch includes a switching region and a front region, wherein the front region is configured to interact with a mating contour of the operating switch such that unintentional switching on of the power tool is prevented. A power tool having a proposed handle is also provided. An improved locking possibility for an operating switch of a power tool can advantageously be provided.

Abstract: A power tool having a first handle, a second handle, and a main body, wherein the second handle projects beyond a rear side of the main body of the power tool by a length a in order to protect the power tool in the event of a fall. In other words, this means that the second handle projects beyond the main body of the power tool in a rear spatial direction and thus forms an overlap to protect the power tool and especially the rechargeable batteries thereof.
