Abstract: An installation apparatus for an expansible anchor has a clamping piston guided in an expansion piston, both of which are perated by compressed air. The clamping piston has a clamping cone for a collet chuck. It slides on the collet chuck, which is fixed in the housing, and clamps a shank of the expansible anchor. The expansion piston displaces an expansible sleeve on the shank of the expansible anchor by an expansion plate which is screwed to the expansion piston and has a hole at its center, through which the shank of the expansible anchor projects into the collet chuck. The apparatus has the advantage of a closed force path as the expansible anchor is expanded, so that the anchor does not need to be steadied by a work-piece. In this manner, slabs or tiles having a small residual wall thickness at the bottom of a drilled hole are prevented from being damaged as the expansible anchor is installed.

Abstract: In a drilling device for producing drilled holes with an undercut, in particular in facing panels of stone, ceramics, concrete or similar materials a drive motor of a drilling shaft is mounted so as to swivel, is displaced outward by a sloping surface, and is driven by a lead screw gear unit to perform a precession movement.

Abstract: A device for a variable division of a motor vehicle boot and for securing a loaded cargo, the device comprises two guide rails arrangeable at a distance apart on a boot floor, at least one supporting panel arranged between the guide rails and displaceable at right angles to the guide rails, rolling devices by which the at least one supporting panel is displaceable to the guide rails and which are arranged in both the guide rails and joined to one another, a sliding block which guides the rolling devices in one of the guide rails, the support panel being rotatably mounted on the sliding guide block and being pivotable from a horizontal position lying on the boot floor into a supportable upright position.

Abstract: The drilling apparatus for making a drilled hole with an undercut includes a drive device for rotating a hollow drilling shaft (3); a drill bit holder (23,38) held in the hollow drilling shaft (3); a drill bit (4,26) having a drilling head provided with laterally projecting cutting edges (25) projecting from the drill bit holder (23,38); a device for swivelling out the drill bit holder (23, 38) with the drill bit from a drilling center line (5) including at least one control element of the drill bit holder, a sliding sleeve (11) surrounding the drilling shaft (3) and a swivelling-out element (21,39) connected to the movable sliding sleeve and engaging the control element to swivel out the drill bit holder (23, 38); and a device for raising and lowering the drive device (2) together with the drill bit holder (23,38) and the drill bit (4,26). In one embodiment the swivelling-out element is a sliding block and the control element is a cam surface in a slot provided in the drill bit holder.

Abstract: A device for producing drilled holes with an undercut has a swivel bearing, a drill shank mounted in the swivel bearing, swivelling means displacing the drill shank in a gyratory movement about a center line of drilling, a displacement element projecting at one side from the swivel bearing and displacing the drill shank against a resilient restoring force, and a ring around which the displacement element moves.

Abstract: A device for producing drilled holes with an undercut in facing panels includes a drill bit with a drill head that produces an undercut, and a drilling table for supporting a facing panel in which the drilled holes with an undercut are to be produced and displaceable in a plane of the drilling table. A trunnion projecting from a rotatable base member and engaging a bearing secured to the drilling table is movable between a first position in which the trunnion axis coincides with the axis of rotation of the base member, and a second position in which the trunnion axis is eccentric to the axis of rotation of the base member to effect swiveling of the drilling plate when the rotatable base is driven rotatably.The device has a mechanism for moving the trunnion between the first and second positions including a lever pivotally mounted on the base member, the trunnion being mounted on the lever, and a piston-cylinder drive secured to the base member for pivoting the lever.
