Definitions

  • Th invention is a key-ring made up of a contiguous [58] Field of Search,...,.. 70/457, 459, 458, 456 R; turn coil spring and of a base to which it releasably is 24/3 K, 123 mounted in the form of a U.
  • Each end of the spring has an end member fixed thereto which comprises a neck portion and a spherical head may passage, this aperture being followed by two seats allowing sliding movement therein of the neck portions but preventing withdrawal of the head.
  • a key-ring comprising a coil spring having at an endthereof an end member provided with a neck and an enlarged head portion.
  • a coil spring is provided at one end with an end member releasably receivable in a base member, the other end being rigidly fixed to the base member.
  • FIG. 1 is a perspective view of a key-ring according to the invention
  • FIG. 2 is an exploded view of the key-ring of FIG. 1;
  • FIG. 3 is a front view of the key-ring of FIGS. 1 and 2 with the-coil spring hanging from the base plate from one of its ends;
  • FIGS. 4a, 4b and 4c are bottom, front and side views, respectively, of a base plate according to a first embodiment
  • FIGS. 5a, 5b and 5c are bottom, front and side views, respectively, of a base plate according to a second embodiment
  • FIGS. 6a, 6b and 6c are bottom, front and side views, respectively, of a base plate according to a third embodiment.
  • FIG. 7 is a bottom view of a base plate according to a fourth embodiment.
  • the key-ring which is to retain a key K comprises, a coil spring 1 of the tension-spring type having contiguous turns and whose ends 2 each receive an end member 3.
  • Each end member 3 comprises an enlarged head 6 connected to an extension piece 4 by a neck portion 5.
  • the extension piece 4, whose diameter is slightly greater than that of the bore of the spring, may either be screwed into an end 2 of the spring 1, or it may be of such a size as to form a press fit into the spring 1: the head 6 and the neck portion 5 lying outwardly of the spring end 2.
  • Spring 1 is normally linear, as shown in FIGS. 2 and 3 but will assume the U-shaped configuration N FIG. 1 when the ends 2 are urged towards each other. It will retain the U-shaped configuration when mounted on a base plate such as that shown in FIGS. 2 and 4a.
  • the base plate 7 is provided with a cut-out forming a central aperture 8 communicating with a pair of lateral slots 10 extending in opposite directions away from the aperture 8.
  • aperture 8 is such as to allow the passage of the head 6 of one end member 3 therethrough, the coil spring being retained in the base plate 7 when the neck 5 of the extension 4 is slid into engagement with one of the slots 10.
  • the transverse dimension or diameter of the spherical head 6 is greater than the transverse width of the slot 10 so that the spring 1 can only be removed from the base plate 7 by sliding the neck 5 along the slot 10 and withdrawing the head 6 through the aperture 8, it being understood that the diameter of the neck portion 5 is smaller than the outer diameter of the spring 1, the latter being greater than the width of the slot 10.
  • one end of the spring 1 is mounted in the base plate 4, as aforesaid, and the end 11 of a key K to be held on the key-ring is moved toward the said end of the spring 1. The latter end is then forced towards the base plate 7 and the corresponding head 6 is passed through the aperture 8 as shown in dotted lines in FIG. 3.
  • the base plate 7 may have several configurations.
  • the base plate 7 of FIG. 4a is shown to have a pair of upstanding flanges 4f adapted to receive an identity tag 9 (FIG. 1) through a chain 12, the top surface of the'base plate 7 being substantially fiat.
  • FIGS. 50 to Sc show a base plate 7 with a substantially rectangular aperture 8 and having a curved outline.
  • FIGS. 6a to 6c show a base plate 7' with a pair of pertures 8", each communicating with a single slot 10', said slots 10" extending colinearly away from the respective aperture.
  • the base plate 7" is in the form of a substantially cylindrical tube.
  • one end of the spring 1 is permanently fixed to the base plate 7; the free end of the spring 1 being releasably engagable in the base plate through an aperture 8' and a slot 10.
  • the permanently fixed end is through the use of a hole 13 having a diameter slightly greater than that of the nick portion 5 but smaller than the outer diameter of the head 6 and of the spring 1.
  • a key-ring comprising:
  • a a normally rectilinear contiguous turn coil spring having at least one open end
  • a base portion formed with an aperture therein, said aperture being of a size to allow passage of said spherical head, a slot in communication with said aperture, said slot being of a width such as to allow sliding passage of said neck portion, the width being smaller than the diameter of said spherical head, the diameter of the neck portion being smaller than the outer diameter of the spring, and
  • the outer diameter of the spring being greater than the width of the slot
  • a key ring comprising:
  • a a normally rectilinear coil spring for supporting at least one key thereon.
  • said coil spring having at least one open end
  • an end member having a neck portion and an enlarged head portion, at least a portion of said neck having a diameter slightly greater than the diameter of said open end
  • a base member provided with an aperture receiving said neck portion and said enlarged head portion therethrough
  • each aperture communicates with a slot dimensioned to receive the neck portion of an end member, but able to prevent passage therethrough of the head portion of an end member, the slots extending generally colinearly in opposite directions away from the respective aperture.
