Abstract:
A hook fastener having a closure for closing a hook mouth. A keeper selectively prevents opening of the closure and includes a body having a base and a hook extending from the base to define a gap. The base has an external face and an opening with a mouth intersecting the external face. The closure includes a shaft and a grip, the grip protruding from the shaft through the mouth. A spring urges the closure such that the shaft may selectively extend out of the opening. The keeper is received to rotate upon the external face. A slot in the keeper extends parallel to the mouth, the keeper selectively preventing the user from retracting the closure from the gap.
Abstract:
A coupling device that requires no manual actuation to achieve coupling features a locking bolt movable along a hole extending into a mouth of a hook body to secure a coupling pin therein. A control lever pivotally connected to the locking bolt opposite the mouth end is biased toward a locked position in which motion of the locking bolt is blocked. To engage the coupling pin and the hook mouth, the coupling pin and an operable pin extending through the hollow locking bolt are brought into contact. This causes an end of the operable pin opposite the mouth to push against the control lever to unlock it from the latching position. The coupling pin pushes the locking bolt out of the mouth so that it can pass by further into it, at which point the lever and bolt return to the locked positions to secure the coupling pin inside.
Abstract:
The present invention relates to a rotary buckle structure which is comprises of a buckle member and a rotary member; the bottom of the buckle member and rotary member are respectively coupled to a downwardly tapered conical body, conical hole and with the same concentric axis, and the length of surface of external circumference is longer than the length of the inner circumference of the conical hole. The arrangement of completing buckle member and rotary member improves the traditional effectively reduces the wearing to prevent the entire buckle set from loosening or falling off, and thus extends the life of use.
Abstract:
A strap fastener for releasably connecting a strap, cord or belt on a garment article is disclosed, the fastener comprising a base member, a strap retainer member and a slider. The base member has an upper plate and a lower plate defining therebetween a guide channel through which the slider is movable. The slider has a guide rail at such a lower edge of a side flange which lies above the lower surface of the base member. A hook is formed, extending integrally from the lower plate of the base and releasably engageable with the slider through a ridge-and-groove formation alternately provided on the hook and the slider.
Abstract:
The present invention relates to a tool for compressing a helical spring of the type typically used in a MacPherson strut suspension system. The tool comprises a pair of spaced apart shoes each having a helical groove formed therein for engaging a portion of the coil of the spring. Each shoe also includes a latchable locking device extendible over the respective helical groove for maintaining the coil of the spring within the groove during the compression operation. The two shoes are maintained in a spaced apart relationship with the associated grooves in facing relationship to one another by a threaded shank member. The threaded shank member includes a separate tool engaging configuration on each end thereof and is employed to effect movement of the spaced apart shoes toward and away from one another during the operation of the tool.
