Abstract
A cord closure for securely retaining flexible cord, drawstrings, and the like in a selected position includes a plunger member, a compression spring, a retaining ring, and a body housing. There is provided means for initially holding the plunger sub-assembly in a pre-assembled position with the spring being compressed so that the holes of the plunger member and body housing can be readily aligned for insertion of a cord. Once the cord is threaded through the aligned holes, the plunger member is depressed downwardly and released to allow the spring to expand and urge the plunger member to move up axially, thereby locking the cord between the plunger member and the body housing.
Claims20
A cord closure comprising:
- a body housing having an open end, a surrounding outer side wall, and a closed end to form a cavity therein, said housing having a pair of holes formed on the outer side wall at diametrically opposed positions for receiving a cord;
- a plunger member having a head, a body portion, and a stem portion, said body portion joining said head to said stem portion and having a transverse throughhole extending diametrically therethrough;
- a compression spring being positioned over the stem portion and having a first end thereof engaging the body portion and a second end;
- a retaining ring having an upstanding portion positioned into the second end of said compression spring;
- means formed on said stem portion for releasably locking said compression spring in a compressed state between said body portion of said plunger member and said retaining ring to define a pre-assembled position for a sub-assembly of said plunger member, spring, and retaining ring;
- and
- said sub-assembly being inserted telescopingly into said cavity of said body housing so as to coaxially align the throughhole of said plunger member with said pair of holes of said body housing for receiving the cord,
- whereby when said head of said plunger member is depressed downwardly and released said locking means becomes disengaged so as to allow said spring to expand and urge said plunger member to move up axially to lock the cord between said plunger member and said body housing.
A cord closure, comprising:
- a body housing having an open end, a surrounding outer wall, and a closed end so as to form a cavity therein, said housing having a pair of holes formed through the outer side wall at diametrically opposed positions for receiving a cord;
- a plunger member having a transverse throughhole extending diametrically therethrough;
- means for resiliently urging said plunger member towards said open end of said housing so as to move said throughhole out of alignment with respect to said pair of holes in said housing;
- means for initially releasably locking said plunger member at a first position relative to said housing so as to restrain said resilient means in a compressed state between said plunger member and said closed end of said body housing so that said throughhole of said plunger member and said pair of holes of said body housing can be readily aligned for insertion of said cord therethrough;
- and
- means for releasing said releasable locking means when said plunger member is depressed inwardly of said housing so as to permit said resilient means to urge said plunger member towards said open end of said body housing.
A cord closure, comprising:
- body housing means having a surrounding outer side wall extending between a first end and a second end so as to form a cavity therebetween, said housing means having a pair of holes formed upon the outer side wall at diametrically opposed positions for receiving a cord;
- plunger means having a transverse throughhole extending diametrically therethrough;
- resilient means for urging said plunger means towards said first end of said housing means so as to move said throughhole out of alignment with respect to said pair of holes in said housing means;
- and
- means for initially releasably locking said plunger means at a first position with respect to said second end of said body housing so as to compress said resilient means between said plunger means and said second end of said body housing means so that said throughhole or said plunger means and said pair of holes of said body housing means can be readily aligned for insertion of said cord therethrough;
- whereby, when said plunger means is depressed downwardly and released, said releasable locking means becomes disengaged so as to allow said resilient means to expand and urge said plunger means to move toward said first end of said body housing means so as to lock said cord between said plunger means and said body housing means.
A cord closure, comprising:
- a body housing having a pair of apertures formed within diametrically opposed portions thereof;
- a plunger member having a diametrically extending throughbore;
- a retaining ring disposed within said body housing;
- means defined between said retaining ring and said plunger member for releasably locking said plunger member at a first position within said body housing so as to align said diametrically extending throughbore of said plunger member with said pair of apertures of said body housing so as to permit a cord to be inserted through said pair of apertures of said body housing and said throughbore of said plunger member when said plunger member is disposed at said first position;
- spring means interposed between said plunger member and said retaining ring for biasing said plunger member to a second position at which said pair of apertures of said body housing and said through-bore of said plunger member are out of alignment with respect to each other so as to lockingly grasp said cord therebetween;
- and
- means defined between said plunger member and said body housing for releasing said releasable locking means of said plunger member from said retaining ring when said plunger member is moved inwardly with respect to said body housing so as to permit said spring means to bias said plunger member from said first position to said second position so as to lockingly grasp said cord between said through-bore of said plunger member and said pair of apertures of said body housing.
