Abstract
Abstract Disclosed herein is a cord grommet, which comprises a female member of the shape of a tube having an approximately rectangular outside cross section and provided at one end thereof with a wall blind except for an oblong hole bored therein for passage of a cord and at the other open end thereof with an outer flange and a male member composed of a shaft having an approximately elliptic cross section and adapted to be rotatably set in position inside said female member and skirt-shaped engaging means adapted to encompass the flange of said female member, whereby a cord is fastened in a twisted state to a panel by a procedure comprising the steps of inserting said cord through the male and female members, bringing the two members into intimate contact with each other, inserting the two members in the coupled state into a perforation bored through the panel and giving the male member a relative rotation.

A cord grommet comprising: (a) a female member of the shape of a tube having a non-circular outside cross section and an approximately circular inside cross section, one end of said tube being provided with a wall having an oblong hole bored for passage of a cord and the other end thereof being open and having an outer flange, said tube being divided by longitudinal slits into two opposed pairs of walls, the members of one pair of which are each provided with an engaging projection on the outside thereof and said tube being provided on the inside thereof with circumferentially spaced recesses and (b) a male member composed of a shaft of an approximately elliptic outside cross section and engaging means, said shaft being adapted to be inserted into said female member through the open end thereof and rotatably set in position therein, said male member including an oblong hole extending throughout the entire length thereof and further provided on the outside thereof with circumferentially spaced protrusions receivable by the recesses of said female member and said engaging means being integrally connected to one end of said shaft and provided on the outer boundary with a claw adapted to be engaged with the edge of the flange of said female member.
Claim 3
Dependent Claim
80 words
The cord grommet according to claim 1, wherein the flange of the female member is provided on the front surface of the flange thereof with a stepped portion and said male member engaging means includes a flange which is provided on the rear surface of said flange with a projection so that when the male and female members are brought into intimate contact and given a relative rotation, the relative rotation will be limited to the fixed angle of 90°.
Claim 4
Dependent Claim
43 words
The cord grommet according to claim 1, wherein the longitudinal slits formed in the opposed pairs of walls of said female member are interconnected at their flange-side ends by insertion of connecting cuts and the interconnected ends are raised to form tongue portions.
Claim 5
Dependent Claim
38 words
The cord grommet according to claim 1, wherein the flange of said male member is provided in the front surface thereof with a groove for admitting a tool serving to give a relative rotation to the male member.
