Abstract:
The present invention provides a connection arrangement for releasably connecting an electrical device and a power control module, the electrical device including an electrically powered functional component, the power control module including a device for controlling the supply of electrical power to the functional component when the electrical device and the power control module are connected. The connection arrangement includes a first connecting portion associated with one of the electrical device or the power control module and configured to interengage with a second connecting portion associated with the other one of the electrical device and the power control module. The first connecting portion including a first locking member and the second connecting portion including a second locking member, wherein when the first and second connection portions are engaged the first and second locking members are movable relative to each other between an unlocked position in which the first and second connection portions are separable and a locked position in which the first and second connection portions are locked together. Preferably, the electrical device is a power tool module.
Abstract:
Die Erfindung geht aus von einer Zusatzhandgriffvorrichtung, insbesondere für eine Handwerkzeugmaschine (12a-e), mit einem Zusatzhandgriff (14a-e), der eine Griffhülse (16a-e) und ein Stützelement (18a-e) aufweist, und einer Dämpfungseinheit (20a-e), die zumindest ein Dämpfungsmittel (22a, 24a; 22b, 24b; 22c; 22d; 22e, 24e) aufweist. Es wird vorgeschlagen, dass das Dämpfungsmittel (22a, 24a; 22b, 24b; 22c; 22d; 22e, 24e) zumindest teilweise in einer radialen Richtung (26a-e) zwischen dem Stützelement (18a-e) und der Griffhülse (16a-e) angeordnet ist.
Abstract:
An apparatus and method for forming a hole in material for non-medical and medical purposes such as a cranial burr hole for ventriculostomy and brain biopsy procedures. The apparatus includes a main unit upon which a drill unit is located. The drill unit includes a drill bit and an on/off switching means. The main unit includes a handle which is suitable for grasping, and an advancing mechanism including a release/engage mechanism, and an advancing lever and an optional on/off switch. The drill unit is advanced a predetermined distance relative to the main unit each time an advancing lever is pulled. In use, the apparatus is placed in a desired position upon the material to be drilled such a patient's skull and is stabilized by a stabilization platform, the apparatus is then turned on, and the advancing lever is pulled to advance the drill unit a predetermined distance relative to a longitudinal axis of the main unit with each pull of the advancing lever. The procedure is ended when the desired depth of penetration has been reached, or the material such as in the case of skull bone, has been completely penetrated.
Abstract:

The drilling machine (100) includes a front handle assembly (118) and an output drive shaft (110) projecting outward from the protruding nose. A fluid attachment ring (120) is rotably arranged around the protruding nose. Further, the front handle assembly (118) is arranged around the protruding nose.
Abstract:
An article having a first structure and a second structure. The first structure includes a structural portion and an overmold portion, which is formed from a resilient material and molded onto the structural portion. The overmold portion is configured to perform an auxiliary function, such as creating a seal portion that is configured to sealing engage the second structure, an isolator portion that is configured to contact the second structure and dampen vibrations that are transmitted thereto and/or an auxiliary gripping surface.
Abstract:
