A buckle, which comprises a female body and a male body, which may be inserted each other and prevents rocking in right and left directions and clattering of the female body and the male body at the time, is provided. A buckle comprising a female body formed with a flat housing and a male body having a pair of right and left flexible insertion legs, wherein when the female body and the male body are inserted to engage, the butting surfaces between the female body and the male body on a plane, that is, butting portions are formed with horizontal straight portions on both sides of the butting portions as well as a concave portion at the center in female body and a convex portion in the male body, or a convex portion in the female body and a concave portion in the male body continuously formed, so as to join the female body to the male body in the condition closely in contact.

Buckle

A resin safety shoe toe cap made from a fiber-reinforced thermoplastic resin, wherein the toe cap resin safety shoe toe cap is constituted from rising parts comprising a front end rising part, a big toe side rising partand a little toe side rising part; a top part; and a base part, wherein the thickness of the big toe side rising partis made to be greater than the thickness of the little toe side rising part. Moreover, the big toe side rising partand the little toe side rising partare connected to the front end rising partby curved surface partshaving different curvatures, and the rising parts are formed so as to rise up approximately perpendicularly to the base part. The safety shoe toe cap not only satisfies the performances in L-class and S-class of JIS T 8101, but also the impact resistance and compression resistance performances stipulated in H-class of JIS T 8101 and safety shoe standards in the CEN Standard, without impairing the ability to fit to shoes and wearer's feet.

Cord holder

Fastening device for clothing

A belt connecting device having a female member and male member engagable with each other; an engaged/disengaged portion of the female member having a substantially U-shaped pinching resilient portion open at a side of a belt connecting portion, having a narrow portion in the middle thereof, and extending substantially on one plane from the other end; an engaging/disengaging portion of the male member having a protruded portion projecting substantially from a rear middle portion of said plate shaped body and at least a belt connecting portion side end face portion thereof having a configuration to be circumscribed by a pinching surface of the pinching resilient portion of the female member; and a substantially C-shaped attachment flange, having a gradually increasing projection, whose rear face engages with a surface attachment face of the pinching resilient portion at an upper end of the protruded portion.

Belt connecting device

A buckle comprises a male member and a female member. The male member is provided with an insertion portion adapted to be inserted into the female member and an insertion hole formed inside of the insertion portion. The female member is provided with a recess in which the insertion portion is to be fitted, and an accommodating portion adapted to communicate with the insertion hole. The accommodating portion is provided therein with an engaging piece swingable in an inserting direction to the insertion hole. The engaging piece is provided with an engaging portion which is to be inserted through the insertion hole. The insertion hole of the male member is formed with a locking surface against which the engaging portion is adapted to abut. The accommodating portion is provided with a pair of receiving portions located at opposite sides of the recess for supporting a pair of abutment portions of the engaging portion, and is adapted to be located on opposite sides of the locking surface in an engaged state of the buckle. Therefore, the buckle has a high engaging force between the male member and the female member, and these members can not be disengaged from each other unintentionally even if tensile force is applied to the buckle.

Cord stopper

A cord end stopper comprising a male member having an engaging member and a female member having an engaging portion for interlocking engagement with the engaging member, the male member and the female member, when joined, defining therebetween a groove for accommodating a cord, the male members and the female member each having a plurality of cord locking means provided in its inner surfaces within the groove across the cord and disposed in staggered relation to the other's locking means, so as to provide, within the groove a zigzag or sinuous path for accommodating the cord therein.

Cord end stopper

A buckle comprises a male member and a female member adapted to couple with each other. The male member includes a fitting projection provided on a base thereof and the female member has a fitting cavity formed at its one end for fitting engagement with the fitting projection of the male member. A tongue-shaped presser plate and the actuating levers of the female member are substantially coplanar with the front wall and the corresponding side walls respectively, of the female member, when the male and the female member are coupled with each other.
