Abstract

A cord fastener composed of a male member and a female member coupled together against displacement each other since laterally outwardly projecting feet of a pair of resilient legs of the male member is normally held in interlocking engagement with a pair of locking teeth on an inner surface of a hollow tubular body of the female member. For attachment of the cord fastener to a cord, the male member is displaced against the resiliency of the legs until a through-hole in a head of the male member is brought into coaxial alignment with a pair of cord insertion holes in the tubular body, thereby permitting insertion of the cord into such aligned holes. When the male member is released from the downward pressure, the male member is urged upwardly by the resilient forces stored in the legs, whereby the cord is firmly gripped by and between the male and female members against displacement.

Dependent claims

A cord fastener comprising:

(a) a male member composed of a head having a transverse through-hole for receiving therein a cord, and at least two resilient legs extending integrally and downwardly from said head and having feet projecting laterally outwardly from lower ends of the respective legs;
and
(b) a female member composed of a hollow body having an axial hole for receiving therein said legs and said head, said hollow body having a pair of diametrically opposite cord insertion holes communicating with said axial hole, and at least two locking teeth disposed below said cord insertion holes and projecting into said axial hole, said locking teeth being lockingly engageable with said feet, respectively, to couple said male and female member, said hollow body further having a downwardly tapered inner surface extending downwardly of said locking teeth for engaging said feet of said legs to urge said male member upwardly, said head further having a cylindrical shape and having at least one guide groove extending axially in a peripheral surface of said cylindrical head, said hollow body having a tubular shape and having at least one guide ridge extending axially on an inner peripheral surface of said tubular body, said guide ridge being slidably receivable in said guide groove.

A cord fastener comprising:

(a) a male member composed of a head having a transverse through-hole for receiving therein a cord, and at least two resilient legs extending integrally and downwardly from said head and having feet projecting laterally outwardly from lower ends of the respective legs;
and
(b) a female member composed of a hollow body having an axial hole for receiving therein said legs and said said head, said hollow body having a pair of diametrically opposite cord insertion holes communicating with said axial hole, and at least two locking teeth disposed below said cord insertion holes and projecting into said axial hole, said locking teeth being lockingly engageable with said feet, respectively, to couple said male and female members together when said male member is inserted into said female member, said hollow body further having a downwardly tapered inner peripheral surface extending downwardly of said locking teeth and engageable with said feet to resiliently flex said legs inwardly toward each other, thereby enabling said feet to slide upwardly toward said locking teeth along said tapered inner peripheral surface under the resilient forces stored in the inwardly flexed legs.
