Abstract: The invention is a bone screw apparatus. The bone screw apparatus has two specialized functions for stabilizing the screw within a bone. The first is a mechanical structure that anchors the screw within a bone and the second is a structure that allows injection of bone cement through the screw assembly and into the interior structure of the bone. The anchoring mechanism functions by an expandable member that slides concentrically over the shaft of the screw. When the expandable member is forced over a portion of the screw shaft with an enlarged diameter, the expandable member extends radially from the screw shaft, and the bone screw is anchored to the interior structure of the bone. The injecting function of the bone screw apparatus functions through the use of a hollow core within the screw shaft. The hollow core of the screw shaft has an inlet at the top of the shaft and at least one outlet near the tip of the screw shaft.

Abstract: An expansible fixing plug (10) has an expansion screw (14), which is located in an expansible fixing plug sleeve (12). In accordance with the invention, a screw thread (30) is of saw tooth construction and a rear part (16) of the fixing plug sleeve (12) is axially extendable. When the expansible fixing plug (10) is subjected to axial loading the expansion screw (14) moves axially in the fixing plug sleeve (12) and the screw thread (30) expands the fixing plug sleeve (12). The expansible fixing plug (10) therefore has a subsequent-expansion behavior when a drilled hole becomes enlarged. The expansible fixing plug (10) can be mounted by hammering in without turning the expansion screw (14). The core diameter of the screw thread (30) enlarges from the front to the rear to increase the capacity of the expansion screw (14) to withstand transverse loading.

Abstract: The present invention is a wall anchor having a novel finger configuration. This wall anchor has a head and barrel portion with a bore extending therethrough and laterally expandable fingers in general alignment with the bore. Instead of a straight channel, a channel having curved portions separates the fingers. The curved portions of the channel define ramp surfaces that at least partially extend into the path of a securing member created by the bore. Thus, when a securing member, such as a bolt, pin, screw, nail or similar object is inserted into the bore to secure the wall anchor to the wall, the securing member contacts the two ramp surfaces, separating the fingers. As the fingers separate, a portion of the fingers near the ramp surfaces deform such that the ramp surfaces rest on an outer portion of the securing member, thus providing a securing force for connecting the wall anchor to the wall and relieving stress on the area at which the fingers are connected to the barrel.
