Abstract: A fastener comprises two, i.e. male and female, members. The female member has a hollow locking body portion, reinforcement portions projecting from the outer periphery of the locking body portion, and diametrically opposed elastic locking pawl portions extending in a substantially V-shaped fashion from the free end of the reinforcement portions toward the lower surface of a top mounting flange. The locking pawl portions face each other on the opposite sides of the locking body portion and each has a substantially arcuate sectional profile. The male member is fitted in one of two panels and detachably coupled to the female member fitted in the other panel.

Abstract: A window glass holder part with a window glass holding groove and a mounting leg part are formed integrally from a plastic material. The inner surfaces defining the holding grooves are formed with adhesive filling grooves facing each other on the opposite sides of the window glass and are open at one end to the outer surface of the holder and also with non-perpendicular prevention walls for preventing the upward displacement of the adhesive filling the adhesive filling grooves. The bottom of the holding groove is formed with a thin groove parallel to the holding groove to permit migration of the adhesive into the thin groove.

Abstract: A plastic screw grommet is disclosed, which has a body formed with a threaded hole and also formed in a lower end portion with a diagonal slit. A side of at least one of divisions defined by the slit is formed with a flexible hook portion adjacent to an edge of the slit and outwardly inclined toward the flange.

Abstract: A ball joint comprises a ball stud containing a ball at the leading end thereof, a socket incorporating therein a receptacle for admitting of the ball, and a resilient metallic ring containing a gap therein and adapted to retain the ball rotatably within the receptacle. The receptacle is formed of a main body and an auxiliary body adapted to be attached fast to the main body, and at least the main body is formed of a plastic material. Retention of the ball within the socket is accomplished by setting the resilient metallic ring in position within the receptacle before attachment of the auxiliary body to the main body, driving the ball into the receptacle thereby causing the equator of the ball to widen the gap in the resilient metallic ring and slide past the ring, and consequently enabling the ring to get hold of the ball.

Abstract: A trim cover clip comprising a hollow tube made of a plastic substance, containing in the wall of the hollow tube at least one slit having the shape of three sides of a rectangle and thereby enclosing therein an engaging piece possessing a free end, and having the inner wall of the engaging piece corrugated to form teeth capable of engaging with the thread on the bolt being passed through the inner hole of the hollow tube is improved by having the engaging piece formed aslant inwardly enough for the free end thereof to thrust deeply into the inner wall of the hollow tube.

Abstract: A plastic one-piece latch for locking a lid comprises a base provided on the underside thereof with a fastener leg, an engaging piece extending from one end of the base and bent abruptly in an oblique upward direction in a manner folded over itself and adapted to make fast engagement with a hook on the lid, and a compression piece extending from the base to a great enough length to collide into the inner surface of the lid at the time that the lid is on the verge of complete closure.

Abstract: Disclosed is a device for holding a linear article on a support body, consisting of a pair of plastic counterparts each comprising a base, an article holding means integrally provided on the upper surface of the base, a notched rod integrally provided on the upper surface of the base and extending outward from one front corner of the base, a guide channel having a catch projection therein and extending inward from the other front corner of the base, and an engaging leg integrally provided on the undersurface of the base. In use a pair of plastic counterparts are engaged with each other by inserting the notched rod of each counterpart into the guide channel of the other counterparts, and the counterparts thus engaged are placed across the width of a support plate with the legs of the counterparts abutting the opposite edges of the support plate.

Abstract: A link rod connector is formed to have two sections connected by a resilient hinge and each section is provided with a semicylindrical leg portion having a resilient catch. In use, the sections are closed onto each other to retain a link rod therebetween in such a manner that the link rod is rotatable within the sections but cannot be extracted therefrom, and then the cylindrical leg formed by the semicylindrical leg portions is inserted into a hole in a link arm so that the link rod is rotatable with respect thereto.

Abstract: Disclosed is a binding clip which comprises an elastic filamentous portion approximately in the shape of the Greek letter ".OMEGA." (omega) and head portions possessed of mutually engageable means attached one each to the extremities of said filamentous portion. After a linear article has been encircled by the filamentous portion of said binding clip, the head portion thereof is brought into inseparable engagement by winding the head portion for thereby twisting the ends parts of the filamentous portion around each other and coupling the mutually engageable means with each other.

Abstract: Disclosed is an improvement in a coupling mechanism for uniting two plates comprising a coupling member and associated apertures in the plates wherein the coupling member comprises a head portion and two legs integrally connected to the head portion and each having a stepped engaging portion on the periphery thereof, whereby when the two legs are inserted in the apertures of the two plates and rotated by 90.degree., the stepped engaging portions catch some selected parts of the circumference edge of the aperture of one of the plates, and clamp these plates in cooperation with the head portion, which is pushed against the other plate. The coupling mechanism according to this invention further comprises means to regulate the rotation angle of the shank of the coupling member at 90.degree., thus preventing the shank of the coupling member from overrunning the stop position at which the stepped portions catch selected parts of the circumference edge of the aperture of one of the plates to be coupled.
