Description
BACKGROUND OF THE INVENTION
This invention relates in general to a pocket-engaging holder
having a magnetic clasp and in particular to an eyeglass case
having a flexible, magnetic strap attached.
Almost without exception, the many millions of persons who depend
on eyeglasses to augment their vision, utilize some form of
carrying case to contain and protect the eyeglasses when they are
not in use. Men, in particular, prefer to use a case which can be
conveniently carried in shirt breast pocket. If such cases are not
equipped with a clasp or clip of some sort, then the case is very
likely to fall from the pocket, particularly when the owner bends
over. Moreover, because eyeglass cases are relatively narrow, they
are likely to fall askew in the pocket unless held.
In order to retain eyeglass cases and the like in a pocket,
resilient clips are commonly used. These clips depend, for their
effectiveness, on the gripping capability of the clip acting on the
pocket material disposed between the clip and the case. If the
resilience of the clip is too great, then the case cannot easily be
withdrawn from the pocket with one hand, and if this is attempted,
there is a tendency for the clip to drag or tear the pocket.
Alternatively, if the clip resilience is insufficient, then the
clip is ineffective. Further, each clip is normally designed to
suit one thickness of pocket material and is not adaptable to a
different thickness of material. Thus, a clip design for a shirt
pocket is likely to be unsuitable for use with a jacket or vest
pocket.
Of the known devices in the prior art, only one utilizes any form
of magnetized clip or clasp to effectuate the holding action.
However, in this device, the clip is structurally rigid and cannot
be utilized as a strap to facilitate removal of the case. Further,
the magnetic action provides a clamping function for an abrasive
material provided on the underside of the clip, and in this sense,
augments, rather than provides, the holding action.
SUMMARY OF THE INVENTION
This pocket-engaging holder includes a case suitable for eyeglasses
and the like and a flexible clasp which holds the case in place by
magnetic attraction between the clasp and the case.
The material of the pocket in which the case is held, is not
susceptible to abrading by the clasp action and the device is
adaptable to varying thicknesses of pocket material.
By virtue of its inherent flexibility and articulated structure,
the clasp may be utilized as a stray to withdraw the case from the
pocket and the clasp is movable independently of the case.
The case is received inside the pocket and it includes a
magnetically attractive element. The clasp provides a flexible
member having upper and lower portions. The upper portion is
attached to the case and the lower portion, which also includes a
magnetically attractive element is disposed outside of the pocket.
The flexibility of the clasp provides it with a capability of
movement in more than one direction, relative to the case, and
renders it suitable for use as a strap for withdrawing the case
from the pocket.
At least one of the magnetically attractive elements is a permanent
magnet. The weight of the magnetically attractive element of the
clasp, acting in conjunction with the clasp flexibility,
facilitates vertical orientation and automatic alignment of the
clasp with the case.
The upper and lower portions of the clasp are interconnected by a
ring-like buckle element which provides the clasp with compound
hinge action providing articulation perpendicularly to the pocket,
and also in a sideways direction.
The underside of the clasp and the front face of the case include
opposing pouch portions accommodating associated magnetically
attractive elements, each pouch providing a smooth facing piece
adapted to cover its associated elements and engage the pocket
material therebetween.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now by characters of reference to the drawing, and first
to FIG. 1, it will be understood that the holder, generally
indicated by numeral 10, includes a case 11 having front and rear
panels 12 and 13 respectively and a flexible, articulated clasp 14
which is attached at one end to the case 11.
In the preferred embodiment, the case 11, which constitutes a first
member, is received within a pocket 16 such as the breast pocket of
a shirt 15, the pocket 16 being formed from a rectangular patch of
material 17, stitched or otherwise attached to the shirt 15.
The case 11 is supported at the bottom of the pocket 16, and the
clasp 14 which constitutes a second member, is disposed outside of
the pocket 16. The pocket material 17 is disposed between the clasp
14 and the case 11. This material 17 is securely held by magnetic
attraction between the flexible clasp 14 and the case 11 by
mutually attracted magnetic elements 20 and 21 carried respectively
by the clasp 14 and the front panel 12 of the case 11.
In the preferred embodiment, the case 11 is formed from a single
sheet of material folded double and stitched to provide a folded
side margin 22, and stitched side and bottom margins 23 and 24
respectively. The upper portion of the folded margin 22 is cut away
and the upper portion of the stitched margin 23 is left unstitched
to provide each of the front and rear panels 12 and 13 with flap
portions 25 and 26 which facilitate entry into the open-ended case
11.
The front panel 12 includes a pouch 27 formed from a strip of
material stitched or otherwise attached to the front fact of said
panel 12. This pouch 27 provides a pocket for the associated
magnetic element 20.
The flexible clasp 14 is preferably formed from the same material
as the case 11, namely leather or plastic, and includes a
relatively short upper portion 30 and a relatively long lower
portion 31. The upper and lower portions 30 and 31 are
interconnected by means of a rigid ring-like member, such as the
buckle 32. The buckle 32 is preferably of metal and includes
interconnected, opposed bar portions 33 and 34.
As shown in FIGS. 2 and 3, the material at one end of the clasp
upper portion 30 is folded around the upper margin of the front
flap 26 and attached thereto by stitching. The material at the
other end of the clasp upper portion 30 is suitably narrowed and
wrapped around the buckle bar portion 30 and stitched to form a
loop 36 accommodating said buckle bar portion 33. The upper end of
the clasp lower portion 31 is likewise narrowed and wrapped around
the buckle bar portion 34 and stitched to form a loop 36
accommodating said buckle bar portion 34.
Each of the loops 35 and 36 is relatively loosely wrapped around
its associated buckle bar, so that the buckle, in effect,
constitutes a compound hinge which provides that the upper and
lower portions 30 and 31 of the clasp 14 may be oriented in
different directions relative to each other as indicated in FIG. 3.
Moreover, the inherent flexibility of the clasp material and the
ring-like nature of the buckle 32 permit a degree of side movement
as well as compound hinge movement. Thus, the clasp 14 may
conveniently be utilized as a hand strap capable of a universality
of movement relative to the case 11.
At its lower end, the clasp lower portion 31 includes a strip of
material attached as by stitching, to its underside to provide a
pouch 28. This pouch 28 is substantially the same size as the pouch
27 provided on the case front panel 12 and the two pouches 27 and
28 are substantially in register. The pouch 28 provides a pocket
for a similar magnetically attractive element 21 to that
accommodated within the pouch 27.
As shown in FIG. 5, each magnetically attractive element consists,
in the preferred embodiment, of a strip of plastic, magnetic
material 37, such as that known under the trade name Plastiform and
manufactured by Minnesota Mining and Manufacturing Company. This
strip 37 is held in a channel-shaped ferrous holder portion 38 and
consists essentially of ferrite particles bound together by a
plastic matrix. The ferrous holder 38 is designed to collect and
concentrate flux at the point of contact with the object to be
held. If necessary, the arms 39 of the ferrous holder 38 may be
extended beyond the face of the plastic strip 37 to increase the
efficiency of the magnet. This arrangement is particularly
advantageous in the situation in which the channel-shaped holders
38 are reversely disposed, as illustrated in FIG. 4.
It will be understood that only one of the magnetically attractive
elements need be magnetized so long as the other element is of a
material, such as a ferrous material, which is magnetically
attracted by said one magnetized element.
It is thought that the functional advantages of this device have
become fully apparent from the foregoing description of parts, but
for completeness of disclosure, the use of the holder and specific
features thereof will be briefly described.
The flexible magnetic clasp 14 is particularly useful in
combination with an eyeglass case. Because of the flexibility of
the clasp 14, which is achieved both by using flexible material for
the upper and lower portions 30 and 31, and also by providing a
buckle 32 interconnecting these two portions, it may be subjected
to a considerable amount of movement independently of the case 11.
The buckle 32, in particular, permits the clasp upper and lower
portions 30 and 31 to be moved relative to each other in a
direction parallel to the plane of the case 11, as well as
transversely of said plane. The clasp upper and lower portions 30
and 31 can also be rotated to a limited extent about their
longitudinal axes. In fact, a universality of clasp movement is
permitted without substantial strain to the stitched connection
between the clasp 14 and the top of the case 11. Moreover, because
of the inherent flexibility of the clasp material, the attachment
between the upper portion 30 and the top of the front panel 12 acts
as a hinge which adds to the high degree of articulation
versatility of the clasp parts. As indicated in FIG. 3, this
acticulation feature permits the clasp 14 to be utilized as a strap
to permit easy withdrawal of the case 11. There is no tendency to
rotate the lower portion of the case 11 against the pocket 16
containing said case.
The provision of pouches 27 and 28 to hold the magnetic elements 20
and 21 in place insures that neither the material of the plastic
magnetic strip 37, nor the metal holder 38 comes into direct
contact with the pocket material 17 of the shirt 15. The strip
material, forming the pouches 27 and 28 is preferably of thin,
smooth leather or plastic to assist in the separation of the
magnetically attractive elements. Further, the use of a material
such as Plastiform for the magnetically attractive elements 20 and
21 provides sufficient magnetic force to hold the clasp 14 securely
in place, even though the magnetic elements are separated from each
other by three thicknesses of material. There is no necessity to
augment the holding power of the clasp 14 by using abrasives or
other substances harmful to the shirt material.
The use of metal holders 38 for the magnetically attractive
elements 20 and 21, in addition to collecting and concentrating
flux at the point of contact with the held object, also serves to
weight the clasp 14. Thus, there is a distinct tendency for the
clasp 14 to fall under gravity action into a vertical orientation
and alignment with the case 11. The mutually attractive elements 20
and 21 are thereby self-aligning and the magnetically attractive
element 20 on the clasp 14 is quickly and automatically brought
within the orbit of attraction of the magnetically attractive
element 21 carried by the front of the case 11. Further, the weight
of the metal holders 38 assists in retaining the case 11 within the
shirt pocket 16.
The lower portion of the clasp 14 is substantially longer than the
upper portion 30 and provides a convenient strap for withdrawal of
the device from the pocket as indicated in FIG. 3. The particular
advantage of this arrangement is that the breaking of magnetic
contact and the lifting of the case 11 from the shirt pocket 16 is
achieved by a single, one-handed movement.
Although conventional ferrous magnets may be used in place of the
Plastiform material, Plastiform is preferred for the reason that it
is anisotropic material having a preferred direction of
magnetization through the thickness, as indicated by the
north-south arrow in FIG. 5. Thus, identical flat magnetic strips
may be conveniently selected and easily oriented so that a flat
north face is oppositely disposed to a flat south face. Plastiform
is a resilient material which may be readily proportioned for a
push-fit within the channel-shaped metal holder 38.
Although the flexible clasp 14 as described is used in conjunction
with an eyeglass case 11, it is not limited to this use. For
example, the flexible clasp 14 may be readily attached to a
pocket-engaging backing piece carrying a magnetically attractive
element and an identification photograph may be attached to the
front of the clasp 14 to provide a convenient identification means
without the necessity of using pins or the like.
