Description
BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates in general to portable article retaining
devices and more particularly, to a key holder constituted of a
ring-forming member and a body member detachably engageable with
the former.
It is an object of the present invention to provide a key holder of
the type incorporating a key ring formed from a length of resilient
wire stock and having a body for detachable engagement with said
key ring and wherein the ends of said ring are received internally
within the body, thereby being obscured from view during usage as
distinguished from current key holders of this general type wherein
the leg portions are of jaw character and are engaged on external
portions of the related body for full visibility.
Another object of the present invention is to provide a key holder
of the type stated wherein the body is adapted to receive flat,
indicia-bearing elements, and means for preventing the received key
ring legs from disruptive engagement with said indicia-bearing
elements during usage.
It is a further object of the present invention to provide a key
holder of the type stated which is adapted to securely maintain
keys thereon and wherein the engagement between said key ring and
the body conduce to a reliably stable interengagement thereby
preventing unauthorized accidental displacement of the keys
thereon.
It is a still further object of the present invention to provide a
key holder of the type stated which is particularly designed for
inexpensive manufacture of the components and ease of assembly
thereof.
It is another object of the present invention to provide a key
holder of the type stated which is durable and reliable in usage,
which is particularly adapted to prevent loss of the
indicia-bearing elements so that the said holders are suited for
advertising and promotional purposes; and which is of light weight
so as to avoid imposing an unduly heavy bulk upon the user's
pockets; and which is adapted for high volume, rapid
production.

DESCRIPTION OF PRACTICAL EMBODIMENTS
Referring now by reference characters to the drawings which
illustrate practical embodiments of the present invention, A
generally designates a key holder, comprising a key ring member 1
and a unitary discoidal retainer or body, 2. Said member 1 is
formed from a length of resilient wire stock bent to define a loop
or partiannular section 3 for receiving keys (not shown) and a pair
of legs 4,4' each of which, at their end extremity or outer
terminal, is flared slightly outwardly, as at 5,5', respectively.
At their inner ends immediately adjacent loop 3, legs 4,4' are bent
inwardly toward each other, as at 6,6', to form a relatively narrow
neck n. Between its outer terminal 5,5', as the case may be, and
its neck portion 6,6', each leg 4,4' is curved or arcuated
outwardly away from each other, as at 7,7', respectively. For
purposes presently appearing, the resilient nature of the material
of construction of member 1 will allow legs 4,4' to be urged toward
and away from each other but with the development of expected
stress.
Retainer or body 2 is formed, preferably by molding from butyrates
which plastics have been found to have the desired strength and
lightness of weight especially suitable for the present invention.
Retainer 2, as stated, is of general discoidal configuration
embodying a rim portion r comprising an outer or peripheral
sidewall 8 having its end faces beveled, as at 9,9', for
border-defining purposes, as will be set forth hereinbelow. The
inwardly directed surfaces of said beveled margins 9,9' are
provided with a continuous undercut 10,10', respectively; with an
inner sidewall 11 of substantially like depth as said outer
sidewall 8 being presented between undercuts 10,10' (see FIG. 4).
Extending between diametrically opposed portions of inner sidewall
ll, and of like thickness and planarwise aligned therewith, is a
partition or post 12. It will be seen that partition 12 divides the
interior of retainer 2 into two distinct portions. Integral with
one side of partition 12, immediately adjacent one end face
thereof, is a thin wall or divider 13 rigid along its outer edge
portion with the adjacent arc of inner sidewall 11. As may be seen
in FIG. 4, said wall 13 is of relatively reduced thickness with
respect to the depth of inner wall 11 and divider 12, so as to
define therewith a compartment 14 which opens toward one side of
retainer 2.
Partition 12 in its side portion adjacent its end face remote from
that which adjoins wall 13, is rigid with a wall or divider 15
which extends toward inner sidewall 11 in a direction opposite to
that of wall 13 and is united along its outer edge with the
confronting portion of inner sidewall 11. Wall 15 is of like
thickness as wall 13 so as to cooperate with the adjacent side
portions of inner wall 11 and partition 12 to form a compartment 16
which opens toward the side of retainer 2 opposite to the side to
which compartment 14 opens. It will thus be seen, with particular
reference to FIG. 4, that walls 13,15 are mutually planar parallel
and with their outer surfaces being immediately inwardly of the
adjacent undercut 10,10', respectively. Formed in rim portion r of
retainer 2 is a pair of axially parallel, spaced apart apertures
17,17' which open at their inner ends on opposite sides of
partition 12 for establishing communication between the exterior
and compartments 14,16, respectively. The spacing between apertures
16,17' is slightly greater than the transverse extent of neck n of
key ring 1, but said apertures 17,17' are of such cross section
that the distance between their mutually remote portions is less
than that between arcuated portions 7,7' of key ring 1.
As shown in FIG. 5, key ring 1 is adapted for detachable engagement
with retainer 2, with such being effected by projection of legs
4,4' through apertures 17,17', respectively, for reception within
compartments 14,16', respectively, on opposite sides of partition
12. The walls of apertures 17,17' effect a camming relationship
with the respective legs 4,4' so that as the arcuated portions of
7,7' pass therethrough, said legs will be forced toward each other
with the development of expected stress. After completion of
passage of the arcuated portions 7,7' the same, under inherent
bias, will return to normal relationship, thereby extending
laterally outwardly of the said apertures 17,17', in which position
accidental dislodgement is inhibited.
In order to withdraw key ring 1 from retainer 2, forceful, axially
directed, outward pulling is required to cause legs 4,4' to be
cammed toward each other against the bias of wire stock for
sufficient mutual compression. By the novel relationship brought
about by the contouring of legs 4,4' and the relative locatIon and
character of openings 17,17' in retainer 2, a stable condition is
developed so that key ring 1 and retainer 2 are reliably maintained
against accidental relative displacement. Yet, despite this
stability, key ring 1 may be easily withdrawn from, or engaged
with, retainer 2 by the application of requisite and properly
directed force. It is to be observed that walls 13 and 15 inhibit
any rocking movement of key ring 1 about its longitudinal axis, as
the same serve as detents against which the legs 4,4' are caused to
abut by such movement. Additionally, walls 13,15 effectively
prevent any projection of the leg extremities 5,5' outwardly of the
related compartment, as abutment of one leg 4 or 4' against its
adjacent wall will limit corresponding movement of the other
leg.
Provided for disposition transversely of retainer 2 and within rim
r are flat, annular indicia-bearing platelike members 18, which may
be formed of paper or the like, and carry on their exposed face
design and/or textual matter, as for advertising and promotion
purposes. Said members 18 are of sufficient cross section for
projection of its peripheral margin into the proximate undercut
10,10', as the case may be. Adjacent wall 13,15 provides a surface
against which members 18 may be presented. Coveringly disposed over
each of said members 18 is a transparent window 19, as fabricated
of plastic, with its margin received within the related undercut
10,10'. Members 18 are thus shielded by walls 13,15 against
damaging engagement with legs 4,4' of key ring 1 so that
inadvertent tearing and the like is avoided during usage.
Referring now to FIG. 7, A' designates a key holder comprised of a
key ring indicated at l' and a retainer designated 2' both of which
are in all respects structurally and functionally identical with
key ring 1 and retainer 2, respectively, of key holder A
hereinabove described. The portions of retainer 2' corresponding to
retainer 2, are given like numerals for facilitating understanding.
Presented for disposition between the outer face of walls 13,15 and
the adjacent indicia-bearing member 18, is a flat, annular disc 20,
the marginal edge of which is received within the related undercut
10,10'. Said discs 20 effectively close compartments 14,16,
presenting a further barrier against accidental damaging contact
between legs 4,4' and the customarily fragile members 18.
Referring now to FIGS. 8 and 9, B designates a pendant having a
body 22 which structurally and functionally corresponds to retainer
2 of key holder A but with the exception to be described below. The
various portions of body 22 are given like numerals as the related
portions of retainer 2 for purposes of description. Extending
through rim r of body 22 is a pair of relatively narrow apertures
23,23' which, at their inner ends, open into the interior of body
22 on opposite sides of partition 12. Said apertures 23,23' are of
substantially reduced cross section with respect to apertures
17,17' hereinabove described and are further distinguished by the
longitudinal axes thereof being slightly inwardly inclined,
convergingly, toward their inner ends.
Provided for engagement with body 22 is an adapter 24 being
fabricated of wire stock to present a loop portion 25 and a pair of
legs 26,26' which converge toward each other and then substantially
intermediate their length are turned abruptly away from each other
to define extended terminal sections 27,27', respectively. Said
adapter 24 is of such stock as may be deformed manually. Therefore,
in assembly, legs 26,26', in rectilinear condition, are extended
through apertures 23,23' to the requisite extent and the assembler
then causes the inwardly projecting portions of said legs 26,26' to
be bent, away from each other, so as to constitute terminals 27,27'
and allow same to be disposed immediately adjacent inner sidewall
11. In such condition, terminals 27,27' secure adapter 24 in
position, whereby loop 25 will cooperate with outer sidewall 8 to
define an eyelet for engagement to a chain or other like securing
member to allow pendant B to be utilized upon key chains and
related articles. After bending of legs 26,26' as above described,
indicia-bearing member 18 and windows 19 may be readily mounted
upon pendant B in the manner above described with respect to key
holders A and A'.
