Embodiment Construction

[0025] The wall plug 1 comprises a body part 2 and a separate head 3 . The main body portion 2 comprises a hollow cylindrical butt portion 4 and a hollow conical main portion 4a defining a central passage having a longitudinal axis. At its butt end, there is a continuous flange or lug 5 projecting radially from its outer surface. The main portion 4a terminates in an arcuate surface 6 at the narrow end of the body portion. The main body portion 4a has at least one channel 7, preferably two opposite such channels, through which they extend from the arcuate surface 6 through a portion of its length, thus forming in the usual manner as an expandable sleeve main part of .

[0026] A series of triangular rib-like projections 8 are arranged longitudinally along the outer side of the main portion 4a. Narrow flaps 9 are provided at discrete locations around the body part 2, each flap tapering from the outer edge of the flange 5 to the outer surface of the main part 4a.

Abstract

A wall plug (1) comprises a body portion (2:30:30a:40) and a rotatable portion (3:31:31a:41) received therein, the rotatable portion having a passageway (13:32:32a:42) therethrough which is offset both from the axis of rotation of the rotatable portion and also from the axis of the passageway in the body portion in which the rotatable portion is received. The rotatable portion can thus be angularly adjusted to a selected position of offset between its passageway axis and the axis of the passageway in the body portion to compensate for a hole drilled to receive the wall plug being out of position. The offset lead-in offered by the passageway in the rotatable position makes screw engagement easier than with a wholly misaligned wall plug. Means (16, 17) are provided for retaining the rotatable portion in its selected adjusted position.

Description

technical field [0001] The invention relates to a wall plug. Such plugs are generally inserted into holes drilled in the masonry and expanded by tightening the inserted bolts to provide fastening screws secured in the masonry. However, "wall" as used herein also includes non-masonry walls, such as plasterboard, and "bolt" includes a pin where in use a portion thereof locks behind the rear surface of the "wall". Background technique [0002] The occurrence of misalignment of drilled holes with conventional wall plugs and screws is a common problem, for example, because inaccurate measurements of distances can lead to incorrect positioning of the drilled holes. This often necessitates the re-drilling of the hole some distance from the desired position for what may be only a small positioning deviation. Contents of the invention [0003] It is an object of the present invention to provide a wall plug which reduces or avoids this p...
