Definitions

  • This invention relates to a cord lock, and in particular such a cord lock which may be assembled onto an article for releasably holding at least one cord.
  • Such conventional cord locks includes a body and a plunger movable within the body. Each of the body and the plunger has a respective hole, and a cord is inserted through the hole of the plunger and that of the body. A spring is positioned between the body and the plunger for biasing the plunger from the body.
  • the cord lock acts as a pinching mechanism, in which the plunger is movable towards the pocket (against the biasing force of the spring) to allow the cord to slide relative to the plunger hole and the body hole, and movable away from the pocket (under the biasing force of the spring) such that the side wall of the plunger hole and body hole combine to prevent the cord from sliding relative to the plunger hole and the body hole.
  • a shortcoming associated with such conventional cord locks is that unless the end of the cord is tied, the cord lock may be loosened from the cord and be lost. It is thus an object of the present invention to provide a cord lock which may be secured on an article, so as to minimize the risk of losing the cord lock upon release of the cord from the cord lock, or at least to provide a useful alternative to the trade and public. It is also an object of the present invention to provide a new method of assembling an article with a cord lock and at least one cord.
  • a cord lock including a body with a front wall, a rear wall, and a base, defining a pocket, a plunger received at least partly within said pocket and movable relative to said pocket, means for biasing said plunger away from said base of said body, and a back plate engageable with said body, wherein at least a first extension, a second extension and a third extension extend from said rear wall of said body, wherein said rear wall of said body includes two holes, each through a respective of said first and second extensions, wherein said front wall of said body includes two holes, each in alignment with a respective of said holes of said rear wall, wherein said back plate includes a pair of arm members adapted to engage with said first and second extensions; and wherein said back plate is movable relative to said body in a direction generally perpendicular to the longitudinal axis of said first extension to secure said back plate with said body.
  • a method of assembling an article with a cord lock and at least one cord including providing an article, a cord lock and at least one cord, said cord lock having a back plate and a body with at least a first extension, a second extension, and a third extension, forming at least three openings on said article, inserting said first, second and third extensions of said body each through a respective of said three openings on said article, moving said back plate on said body in a direction generally perpendicular to the longitudinal axis of said first extension to secure said back plate with said body, and inserting said at least one cord through the cord lock.

  • the cord lock includes four basic components, namely, a body 12, a plunger 14, a spring
  • All these components may be made in plastic or metal. It is also possible to form the body 12, plunger 14 and the back plate 18 in plastic, and form the spring 16 in metal.
  • the body 12 has a front wall 20, an opposite rear wall 22, and a base 24, thus defining a pocket 26 with an open upper end.
  • Two holes 28, 30 are formed on the front wall 20 of the body 12.
  • Two generally cylindrical extensions 32, 34 integrally formed with the body 12 extend perpendicularly from the rear wall 22 of the body 12. Through each of the extensions 32, 34 is formed a respective hole 36, 38, which also go through the rear wall 22.
  • the hole 28 in the front wall 20 is aligned with the hole 38 through the extension 34 and the rear wall 22, and the hole 30 in the front wall 20 is aligned with the hole 36 through the extension 32 and the rear wall 22.
  • a cord may be inserted through the hole 28 into the pocket 26 and through the hole 38; and a cord may be inserted through the hole 30 into the pocket 26 and through the hole 36.
  • extension 34 has a cylindrical stem portion 34a and a broadened head portion 34b.
  • the extension 32 is of the same construction.
  • the body 12 is integrally formed with a third extension 40 which extends perpendicularly from the rear wall 22.
  • the third extension 40 is in the generally shape of a letter "T".
  • an upwardly extending protrusion 42 for engagement with one longitudinal end of the spring 16.
  • the plunger 14 such has a body portion 44 and a slightly broadened head portion 46, and an elongate recess 48 is formed in the body portion 44.
  • a protrusion 50 is formed at a closed end of the recess 48 for engagement with another longitudinal end of the spring 16.
  • Two holes 52, 54 are formed in the body portion 44 of the plunger 14.
  • the plunger 14 When assembled, at least part of the plunger 14 is received within the pocket 24, such that the plunger 14 is movable relative to the body 12 in the pocket 24 upwardly and downwardly, i.e. as indicated by the double-ended arrow F-F in Fig. 16, which is perpendicular to the longitudinal axis D-D of the extension 34 and the longitudinal axis E-E of the extension 32, both of the body 12.
  • the spring 16 biases the plunger 14 away from the base 24 of the pocket 26. It should be understood by persons skilled in the art that although the spring 16 is shown here as a separate component, it is possible instead to have a biasing means integrally formed with the plunger 14 or with the base 24 of the pocket 26, to achieve the biasing function.
  • the effective clearance through the cord lock 10 varies, such that the clearance is largest when the plunger 14 is closest to the base 24 of the pocket 26 and is smallest when the plunger 14 is furthest away from the base 24 of the pocket 26.
  • such includes two outer arms 56,
  • Both outer arms 56 are resilient and may thus be pulled or pushed slightly away from the central longitudinal axis H-H of the back plate 18.
  • a resilient tongue 66 is integrally formed with a longitudinal end 64a of the slot 64, and extends towards, but does not contact, another longitudinal end 64b of the slot 64.
  • the free longitudinal end of the tongue 66 is away from the longitudinal end 64b of the slot 64 by a distance which equals to or is slightly larger than the thickness t of the extension 40 of the body 12 (see Fig. 15).
  • Two stepped portions 68, 70 are formed at the longitudinal end 64b of the slot 64.
  • Figs. 19 to 23B show the steps of assembling the lock cord 10 onto an article 72, in which Fig. 22B is a side view of Fig. 22A and Fig. 23B is a side view of Fig. 23A.
  • the article 72 may be a piece of fabric forming part of a rack sack or back pack or a wall of a luggage.
  • the spring 16 is firstly received within the pocket 26 and the plunger 14 is then fitted into the pocket 26 so that the spring 16 engages on one end with the protrusion 50 of the plunger 14 and on the other end with the protrusion 42 on the base 24 of the body 12, to bias the plunger 14 away from the base 24 of the body 12.
  • the head portion 46 of the plunger 14 extends above the pocket 26 of the body 12, to be operable by a user.
  • Three holes 74, 76, 78 are formed on the article 72, as shown in Fig. 21.
  • the holes 74, 76 are circular in shape and the hole 78 is rectangular in shape.
  • the holes 74, 76, 78 are sized and shaped for receiving therethrough the extensions 32, 34, 40 respectively.
