Definitions

  • key-holders which consist of rigid rings which may be open when necessary.
  • key-holders are known in which the keys are held by a chain the ends of which are connected together by fastening means of various types.
  • This latter type of key holder has the advantage of providing a more flexible connection between the different keys than is provided by the rigid rings. This makes it possible to insert the set of keys in the pocket of a persons clothing so as to take up less room, since the keys can position themselves with respect to each other in dependence upon the space available.
  • the present invention relates to a key holder of the chain type which avoids the foregoing inconveniences.
  • This key chain is characterized by the fact that it comprises a rigid first member having a concavity and a resilient second member the convexity of which corresponds to the concavity of the first member so that it can be elastically engaged there- 'within.
  • the chain which holds the keys is connected at one end to a point on the rigid first member and at its other end to a point on the flexible second member.
  • the chain which holds the keys carries at each end two branch chains which are connected on the one hand to two sides of an opening in the rigid member and on the other hand to the two ends of the resilient member.
  • the edge of the concavity of the rigid member is provided with a central groove adapted to receive the resilient member, which is held in that groove by its own elasticity after having been squeezed into the concavity.
  • the keys are held on the key ring with double security because even when the rigid and resilient members are not interfitted, the keys are retained on the chain unless deliberately removed by causing them to travel over a particular path of travel which is necessary to bring this about.
  • FIG. 1 is a view showing a preferred embodiment of the invention with the key chain open;
  • FIG. 2 shows the key chain of FIG. 1 in the closed position
  • FIG. 3 is a sectional view taken along the line Ill-Ill of FIG. 2;
  • FIG. 4 is a view showing how a key is positioned to pass over the resilient member.
  • FIG. I shows the rigid member I which. in the present case, is generally C-shaped. but which may have a different shape so long as it has a concave edge 2 leading to an opening 3.
  • FIG. I also shows that the resilient member 4 has a shape mating with that of the member 1.
  • the concave edge 2 of the member I defines a median groove which receives the resilient member 4 as shown in section on FIG. 3.
  • FIG. 1 also shows the chain 5 which connects the keys, such as 6.
  • the chain 5 terminates at each end in branch chains 7, 8, 9 and 10.
  • the branch chains 7 and 8 are connected to the rings 11 and 12 on opposite sides of the opening 3 in the rigid member I, while the branch chains 9 and 10 are connected to rings 13 and 14 at the ends of the resilient member 4, which may advantageously consist of a spring having a rectangular section.
  • FIG. 2 shows the key chain in the closed position with the resilient member 4 engaged inside the concave opening 2 in the rigid member 1.
  • the hole in the key 6 is then passed over one of the rings on the elastic member and the branch chain which is attached thereto.
  • a key may be effectuated from either end of the chain carrying the resilient member or from the side of the chain carrying the rigid member, to the extent of course to which the hole in the key is large enough to be able to pass over the rigid member.
  • the shape of the cavity in the rigid member may be different from the one shown in the drawing. the essential characteristic of this cavity being that it is capable of holding the resilient member. which must have a corresponding shape.
  • the resilient member could be held inside the rigid member by something other than a median recess in the rigid member in which the resilient member is located.
  • Key holder which comprises an arcuate, generally C-shaped rigid member having an elongated concave surface defining the inner edge of the C. said concave surface being provided with a median groove extending lengthwise thereof. an arcuate resilient member mating with said groove and dimensioned to be received within said groove without protruding radially therefrom, and a chain connected by one of its ends to said rigid member and by its other end to the resilient member.
  • each end of said chain terminates in two branch chains, with each branch chain at one end of said chain being connected to a different one of the ends of said rigid member and each branch chain at the other end of said chain being connected to a different end of said resilient member.
