A riveting structure and a riveting method are provided. The riveting structure includes a first metal element and a second metal element. The first metal element includes a first upper surface, a pressure-receiving portion and a recess portion. The recess portion is recessed from the first upper surface. The pressure-receiving portion is protruded from a surface of the recess portion. The second metal element includes a second lower surface and a protrusion portion and has a through hole. The protrusion portion is protruded from the second lower surface and correspondingly disposed in the recess portion. The through hole penetrates the second metal element via a central part of the protrusion portion. The pressure-receiving portion is correspondingly received in the through hole and is adapted to be pressed and deformed to be riveted to the through hole.

It is described herein an adjustable rigid clip assembly comprising an anchor plate joined with a connector plate and a slide plate. The anchor plate is joined with the connector plate at a juncture having a juncture angle between the anchor plate and the connector plate in a range of between 0 and less than 180. The connector plate comprises at least one connector plate slot and at least one connector plate lock. The slide plate may comprise at least one slide plate lock. The at least one slide plate lock may be engaged with the at least one connector plate lock. The slide plate may further comprise at least one slide plate tab passing from the slide plate through the at least one connector plate slot.

A method is provided for connecting a ball to a first component having the following steps: providing a first component which has a through-hole; providing a ball and inserting the ball into the through-hole such that the ball protrudes out of the first component at opposite sides of the first component; placing a first pressing tool on the ball from a first side of the first component and placing a second pressing tool on the ball from a second side of the first component; plastically deforming the ball by pressing together the pressing tools, wherein material of the ball flows both on the first side as well as on the second side of the first component, such that material of the ball covers an edge of the through-hole on the first side and on the second side of the first component, whereby a formfitting connection is produced between the ball and the first component.

An ultrasonic bonding jig includes: a plurality of protrusions; and a planar portion among protrusions formed among base ends of the protrusions. The protrusions have side surfaces of tapered surfaces, the side surfaces being positioned in a vibration direction. At the tapered surfaces, an inclination of a tangent at distal ends of the protrusions, with respect to the vibration direction, is larger than an inclination of a tangent at the base ends of the protrusions, with respect to the vibration direction.

A sandwich panel includes a reinforcement member having a recess formed to extend in a longitudinal direction over a predetermined length and open laterally. The thermoplastic resin core material has a rectangular flat board-like shape, and includes a protrusion which is disposed on a peripheral side surface portion thereof and which is capable of being laterally press-fit with respect to the recess. The protrusion has opposing surfaces respectively opposing mutually opposed inner surfaces of the recess, the opposing surfaces being oriented so as to protrude from the peripheral side surface portion. At least one of the opposing surfaces is provided with a plurality of protuberances disposed at an interval in the longitudinal direction. Each of the protuberances has a predetermined height from the opposing surfaces enabling the protuberances to tightly contact the inner surfaces of the recess at the time of press-fitting.

It is described herein an adjustable rigid clip assembly comprising an anchor plate joined with a connector plate and a slide plate. The anchor plate is joined with the connector plate at a juncture having a juncture angle between the anchor plate and the connector plate in a range of between 0 and less than 180. The connector plate comprises at least one connector plate slot and at least one connector plate lock. The slide plate may comprise at least one slide plate lock. The at least one slide plate lock may be engaged with the at least one connector plate lock. The slide plate may further comprise at least one slide plate tab passing from the slide plate through the at least one connector plate slot.

A joint structure is provided in which a first panel and a second panel are joined together by mechanical clinching. The joint structure includes a join region that is formed so as to extend in an elongated shape by forming plural clinched portions in a given arrangement by mechanical clinching. At least one clinched portion of the plural clinched portions is clinched from an opposite panel side from other clinched portions of the plurality of clinched portions.

A stud bridge member used in the construction industry to span horizontally between studs is disclosed. The stud bridge member has at least one set of notches that engage with the stud and eliminate the use of a stud bridge clip and its associated costs and installation time for that stud.

Provided are a method for manufacturing a Figure-T shaped metal part using a metal plate or a metal rod split by a method for splitting longitudinally an end part of the metal plate or the metal rod having a rectangular, polygonal, or elliptical shape, in which the length of incision in the split portion can be freely adjusted and smooth split face can be formed; a Figure-T shaped metal part manufactured by such method. The method for splitting is characterized by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.

A fastening device including a back plate, a rear cover and an elastic piece is provided. The rear cover is arranged on the back plate and has a protruding portion. The elastic piece is arranged between the back plate and the rear cover. The elastic piece has a first opening, and the protruding portion passes through the first opening, and the first opening is a tooth-shaped structure.
