Abstract: An anchor for a pedicle screw having an anchor body comprising a proximal end, a proximal portion, a distal portion, and a distal end, and a through-hole through the anchor body from the proximal end to the distal end. The through-hole defines a long axis of the anchor, and is provided with undersized female threads in the proximal portion and a reduced inner diameter in the distal portion. The reduced inner diameter causes expansion of at least the distal portion of the anchor body when a screw is inserted into the through-hole. The anchor is further provided with a plurality of ridges on an exterior surface of the anchor body, the ridges configured to reduce the likelihood of pullout when the anchor is inserted into a vertebra and a screw is inserted into the through-hole.

Abstract: The present invention relates to a bone-fixation anchor comprising a rigid expandable part and a soft part. The rigid expandable part secures the anchor with respect to the bone and the soft part enables the anchor to fit any bone screw on the market.

Abstract: A dual expansion anchor configured for use in anchoring an implanting portion to an anchor point. A dual expansion anchor can be of particular use in anchoring soft tissue to a bone. A dual expansion anchor can have an expander and an anchor body. The expander can be sized and shaped so that it causes radial expansion of a first end and a second end of the anchor body when the expander is moved to a deployment or expansion position within the anchor body. The anchor body can include features to positively retain the position of the expander when the anchor body is deployed.

Abstract: An element for fastening accessories to metal window and door frames includes a monolithic metal body with a cylindrical central portion having a threaded inner hole. An insertion portion has a cone frustum shape with decreasing diameter from the diameter of the cylindrical central portion towards one end. A stop portion includes a circumferential throat delimited by a shoulder whose outer diameter is greater than the diameter of the cylindrical central portion. The outer diameter of the shoulder is joined to the cylindrical central section by a cone frustum shaped segment. A first series of through longitudinal grooves extends on a part of the length of the cylindrical central portion and on the insertion portion and defines a first section deformable radially inwardly relative to a non-deformed resting configuration.

Abstract: An alignment pin or fastener includes a radially eccentric part such that when the fastener is tightened, the eccentric part shifts radially to simultaneously align the holes of two plates in a radial direction and clamp the two plates together in an axial direction. The bi-directional fastener includes two heads at opposite ends of a shaft, wherein the two plates become sandwiched and clamped between the two heads. The shaft and the two heads remain fixed relative to each other, so turning one head turns the other. This allows the fastener to be tightened even when only one of the heads is accessible.

Abstract: This invention relates to one-strike wedging type blank nails for use in rigidly joining, in a simple operation, wooden articles in manufacture of furniture, or ceramic articles (such as roofing or other tiles) or metallic articles in the building and construction industry, for example. Such a blank nail includes a main body in the form of a hollow pipe, and a pair of expander elements attached to opposite ends of the main body. The main body defines split slots extending axially at the opposite ends thereof to form wedging portions. Each of the expander elements includes a contained portion fitted into the main body, a large diameter portion having a larger diameter than the contained portion, and a flare portion formed between and continuous steplessly with the contained portion and large diameter portion. The large diameter portion defines an outward end surface acting as an input surface for receiving a compressive force applied in a direction to move the expander elements toward each other.

Abstract: A locking apparatus intended to be anchored in the bore of an element and to receive rotatably by snap-in closure a mating element provided with an undercut head. The locking apparatus according to the invention includes a substantially cylindrical body having first and second ends. Outwardly directed gripping means are arranged in the peripheral surface of the body at its first end. The body has a coaxially arranged cavity which narrows toward an opening in the first end. The cavity extends to the second end of the body and the body is provided there with an inwardly directed flange. The body is expansible or flexible at the first end.

Abstract: An expander device for anchoring in a hole to secure a castor to a part which forms the hole, comprises a conical expander engaged in a sleeve having a conical interior. The expander and the sleeve are mouldings of reinforced plastics material. The expander is screwed onto a coaxial bolt with a 3-start thread. The sleeve is axially slotted from either end, the slots from one end being angularly spaced from one another by 90.degree. as are the other slots with which they are assymetrical so that alternate major and minor sleeve portions are formed between adjacent slots. Deformation takes place predominantly in the minor portions as the sleeve is expanded by axial movement of the conical expander into the internal taper of the sleeve which is caused by rotation of the bolt.

Abstract: An insert assembly includes a frustoconically shape cone nut (10), a cylindrical shell (20) and a bolt (36). The cone nut (10) has a longitudinal bore (12) which is tapped to accept the threads on the bolt. The shell (20) has projecting barbs (28) arranged in a helical pattern on the shell's outer surface. The assembly, comprising the bolt through the shell and threaded into the smaller diameter end of the nut cone, is driven into a bore in the work piece. The bolt is then rotated causing the cone nut to penetrate the shell resulting in radial expansion of the shell whereby the barbs become embedded in the work piece. A keying feature between the nut and the shell prevents nut rotation with the bolt.

Abstract: A binder for panels comprises a main binder part and a wedge member so constructed that the forced insertion of the wedge member into the main binder part causes the split portions formed in the main binder part to spread out and the expansion of the split portions serves to fasten two panels to each other. Into the main binder part set in the perforations formed in advance in the panels, the wedge member can be inserted from either of the outer surfaces of the two panels.
