Abstract

The invention contemplates a key retainer with a key-retaining bail extending beyond one end of a case, for selective retention of one or more keys. The combination involves the bail formed as an integral hook-like part of pivoted body structure within the case. Pivotal action is limited, and deliberate manual actuation of the body structure against a preloading spring is necessary to displace the free end of the hook from (a) a first normally retained position in which the hook is effectively closed by its relation to the case, to (b) a second and temporary position in which the free end of the hook is sufficiently upwardly offset from the case to permit selective key insertion in and/or removal from the bail.

Claims

1. In a key retainer or the like, a case defined by and between spaced edge-fitted front and back panel members, with an opening at one end, a bail member including a body portion essentially contained within the space between and pivotally connected to said panel members, said bail member also including a C-shaped bail portion integrally connected at one end to said body portion and extending essentially outside said panel members via the end opening, said panel members and said body portion having aligned pivot apertures, rivet means through the aligned apertures and serving to retain said panel members in assembled relation to each other and to said body portion while also supporting said bail member for a limited angular range of pivoted bail-portion movement external to and with respect to said case, the other end of said bail portion being spaced from said body portion such that (a) in one limiting pivoted position the said other end of said bail portion coacts with the adjacent region of said case to define an effectively closed key-retaining bail loop and (b) in a second limiting pivoted position said other end of said bail portion is spaced from said case to an extent permitting selective key application to or removal from said bail, and spring means coacting between said bail-member body portion and said case and resiliently urging said bail member in the direction of said one position.

2. The key retainer of claim 1, in which the pivot apertures of said panel members are located generally centrally of and near said one end of said case.

3. The key retainer of claim 1, in which the fitted edges of said panel members include at least one edge wall along the edge near said one end of said bail portion, said first limiting position being determined by interfering abutment of said body portion with said one edge wall, and said second limiting position being determined by interfering abutment of said bail portion with said one edge wall.

4. The key retainer of claim 3, in which each of said abutments occurs at a radial offset from the pivot axis, which offset is at least substantially one half the effective span of the case opening.

5. The key retainer of claim 1, in which the fitted edges of said panel members include at least one edge wall along the edge near said other end of said bail portion, and in which said spring means comprises a stiffly compliant generally V-shaped member with one free end in compressionally preloaded abutment with said one edge wall and with its other free end in compressionally preloaded abutment with said body portion at a location below the pivot axis.

6. The key retainer of claim 5, in which said other free end is characterized by a laterally outward projection, and in which said body portion has a locating notch engaging said projection.

7. The key retainer of claim 5, in which for both said limited positions the location of spring engagement with said body portion is beneath the geometrical line between the pivot axis and the uppermost point of contact of said spring means with said one edge wall.

8. The key retainer of claim 6, in which said notch is radially offset beneath the pivot axis, to the extent of at least substantially one half the effective span of the case opening.

9. The key retainer of claim 1, in which said panel members are characterized by continuous edge walls in telescoped interfit, from one to the other end of the lateral extent of the end opening of said case.
