The extended legs each include a pair of tab members for catchably receiving the support legs. The tray includes a plurality of threaded inserts for allowing the attachment of various accessories.

A keystroke structure (1) comprising a baseplate with insert holes are considerably spaced; the baseplate further comprises a membrane circuit board; an electrically conductive and round in shape resilient body is on the circuit board, a first key frame and a second key frame are on the rim of the resilient body; the first key frame and the second key frame comprise two protruding hinged arms at one end and two extending posts at the other end; the posts comprise a shaft lever respectively; the shaft levers can thread insert the holes on the hood frame; furthermore, the posts comprise a protruding tubes each where they are connected with the first key frame and the second key frame; the tubes comprise a through holes each which the hinged arms thread such that the first key frame and the second key frame can be connected in “Y” shape. A key cap is inserted on the first and the second key frame, while assembly, since the posts have only one end stretch out to the baseplate, the assembly is easier and faster, the structure is simpler to save manufacturing cost. The first and the second key frames are connected together to support each other, the supporting strength is stronger, the slide is smoother.

A threaded collapsible insert is utilized for insertion into a hole in a workpiece for subsequent installation of a threaded fastener. The insert has a axially-aligned opening extending for most or all of the entire length of the body of the insert. The hollow body has a first section and a second section, where the wall thickness of the first section is less than the wall thickness of the second section, such that the first section preferentially collapses upon application of a linear force to the insert. The second section comprises internal threads for engaging the fastener. The head member has a top side and an underside. The underside of the head member may comprise a plurality of knurls radiating outwardly on the underside of the flange. The outside of the first section may also comprise a plurality of axially aligned rib members extending from the proximal end to the distal end.

A turbocharger has a shaft formed of a strong material such as steel and an impeller formed of a relatively weaker material such as aluminum alloy. The impeller is mounted on the shaft by means of an internally-threaded insert, for example also of steel, interference fitted into the impeller hub. To prevent loss of the interference fit between the insert and impeller during thermal and speed excursions of the impeller during operation of the turbocharger, a constraining ring is fitted to the hub of the impeller. The ring is of a material having a lower coefficient of thermal expansion than the material of the impeller and surrounds at least a part of that axial length of the impeller which overlies the insert.

An improved action for a bolt action rifle. The action includes a receiver containing a bolt; the bolt having two to three locking lugs surrounding a bolt face; and a threaded insert that joins the rifle barrel to the receiver. The insert also includes a series of locking lugs that mate with the locking lugs on the bolt. The position of the insert lugs relative to the barrel will position the bolt face relative to the barrel's chamber when the bolt is closed. Thus, the insert and barrel can properly set the rifle's headspace. The insert and receiver are preferably each provided with a locking lug, that serve to align the axes of the insert and receiver. The threads of the insert and the barrel are co-axial which serves to align the axes of the insert and barrel. Thus, assembled, the receiver, insert and barrel will be substantially co-axial.

An improved chemical mechanical polishing retaining ring. A representative embodiment comprises a base portion made from a wear-resistant plastic material, and an upper portion, or backbone portion, made from a stiffer and more wear resistant material. One of the base or backbone portion is preferably overmolded onto the other. The base portion can be generally defined by a flat pad-contacting surface, an outer surface, and an inner surface. The base portion can additionally include channels extending from the outer surface to the inner surface to facilitate transfer of slurry to and from the substrate to be polished during the process. One or both of the base portion or backbone portion further includes a plurality of circular ribs that serve to create additional bonding surface with the overmolded material. The retaining ring may additionally includes a plurality of bosses with threaded insert holes by which the retaining ring is attached to a chemical mechanical polishing system.

A golf club putter head has a unique, geometric configuration that is advantageous for achieving consistently accurate putting shots. The golf putter head of the invention is characterized by a convex complexly contoured ball impact surface and by a high bridge that extends lengthwise at the face of the putter to join the heel and toe. The end extremities of both the putter heel and toe are curved with a complex and unique geometric curvature. Vertical, tapped, chamfered bores are defined in both the putter toe and the putter heel to receive externally threaded inserts. The inserts may be hollow so as to accommodate a variable number of disc-shaped weights, the number of which is individually selected by each golfer. Alternatively, the inserts may be solid structures of a weight suitable to the individual golfer.

A threaded insert for use in a composite and/or honey-comb matrix has a nut member disposed within a plastic housing. The threads of the nut member have a free running thread section and a thread lock section. When a fastener is made up into the nut member, a surface on the nut member engages an opposite-facing surface on the plastic housing, thereby reversing the nut loading from tensile loading to compression loading. A thermoplastic embodiment of the nut member may be fabricated to meet the specifications of aircraft manufacturers required for the SL2334 insert, including thread reusability, tensile loading (pullout load), shear, and interchangeability with the metal component currently in use.

An apparatus for retrofitting the opening of the neck of a bottle with a screw closure. An insert is provided that is configured to be positioned within the neck of the bottle for receiving the external threads of the lower end of a screw closure which is inserted into the opening of the bottle and rotated for securement therein. In one embodiment the insert may be secured in the neck by an adhesive. The positioning of the threads in the lower portion of the neck of the bottle affords a smooth and consistent pour of the wine from the bottle.

The present invention relates to a system and device which allows the replacement of a damaged thread in an object with a thread identical to the damaged thread by enlarging the original threaded hole and inserting a thread-insert in a newly threaded hole in the object which has an internally threaded hole identical to the original threaded hole. The thread-insert is fastened into the enlarged hole using a thread that securely holds it in place. When the thread-insert is threaded into the enlarged threaded hole, a pocket formed below the drive head of the thread-insert causes metal flow into the pocket to create a seal between the thread-insert and the object.

The present invention is directed to a threaded insert having an internal threaded surface and an external threaded surface. The threaded surfaces have threads that are threaded in opposite directions. Thus, if the internal threaded surface is a right handed thread, then the external threaded surface will be a left handed thread. Through the use of the opposite direction threads the insert counteracts torque applied to a threaded fastener as it is inserted or removed. This results in a threaded insert that both resists over tightening of the fastener, and assists in the removal of the fastener from the insert.
