Definitions

  • This invention has for an object the provision on the flat sides of the hemi-spherical head portions of the key retaining member of interengaging parts which will prevent relative movement of the engaged flat sides in the plane of their engagement.
  • FIGs. 1 and 2 are front elevational views showing in enlarged form a key retaining member embodying the invention
  • Figs. 3, 4, 5 and 6 are sectional views thereof taken on the lines 3-3, 4-4, 55 and 6 6, re-
  • Fig. 7 is a front elevational view of an open key case containing a plurality of the key retainingmembers; and 0 Fig. 8 is a. fragmentary cross sectional view thereof.
  • the key retaining member is constructed in the same general manner as disclosed in the above identified application except that it is made up u from wire of round cross section (Fig. 6) and embodies the aforesaid feature of improvement. It is made of a piece of spring metal in the form of a stirrup shaped loop having a bottom curve I0, long and substantially straight sides I I, a short neck portion I2, where the sides becomes substan- 6 tiallyparallel, and a ball head made up of mating and substantially hemi-spherical sections I3. The loop is so made that the spring pressure normally holds the two halves l3 tightly together so as to give the effect of an integral ball-shaped 1d head.
  • the inner or circular faces of the head sections 13 are flat surfaces except that there is provided on one a male part I I of suitable shape, such as the hemi-spherical projection shown in Fig. 4, and 15 on the other a female part l5 of complementary shape, such as the hemi-spherical recess shown.
  • the slot I8 is of a size to 'freely receive neck 1 I2.
  • a plate 20 is mounted to slide longitudinally in the member l1 and can be moved by a flngenpiece 2
  • covers theenlargenients I! when in the position shown, to apex-tent such as to prevent removal of the heads l3 from the cylinder "but, I. when moved to the left by" the finger pieceflfg-uncovers these enlargements and enables the heads to be lifted therethrough.
  • Practical use of the key case has proved that trouble often occurs with damage and II loss when key holders of the split-head type are used without the improvement of this invention.
  • a key retaining member comprising, a stirrup-shaped loop of stiif spring wire having its sides brought together to form a neck portion and a I -shaped head portion at the upper end, said wir having each end upset into substantially h -spherica1 form with the flat faces of said h '-spherical ends matching to form said head portion and.
  • a key retaining member comprising a stirrup shaped loop having its sides brought together to form a neck portion and above the neck portion a substantially ball-shaped head, said head being mounted within said support with its neck portion passing out through said slot and the head portion being removable from the support or insertable therein through saidenlargement, said loop comprising a single piece of stiff spring wire having each end upset into substantially hemispherical form with-the flat sides of each hemispherical end matching one another to form-said ball shaped head and held together under sumcient spring pressure from the sides of the loop to put the head portion in condition to operate as a ball element within said hollow cylindrical support, the mating faces of said hemi-spherical ends having interiitting parts for maintaining them, while held together by said spring pressure, 0 against relative displacement in the plane of said matched faces and preventing the one from
