Abstract
A case for multiple pairs of eyeglasses has a top surface and an opposing bottom surface, a front surface and an opposing back surface and defines a volume for receiving eyeglasses with a length orientation of the eyeglasses substantially parallel to the front of the case. The case is formed from a cover portion and a base portion, hinged together at a pivot line that extends across the bottom of the case parallel to the length orientation of a pair of eyeglasses stored in the case. Preferably, the pivot line is offset on the bottom of the case so as to be closer to the back than the front. The pivot line forms a part of a mating line between the cover portion and the base portion. Preferably, the mating line extends obliquely upward from the bottom, across the ends of the case, and across the top. A divider separates the internal volume of the case into two compartments, each accommodating one pair of eyeglasses. The compartments are offset obliquely, allowing the top-to-bottom dimension of the case to be minimized for easier, more convenient carrying in a jacket or shirt pocket, while still allowing the use of rigid material, providing better protection for the eyeglasses than can be provided in a soft-sided case.
Description
FIELD OF THE INVENTION
This invention relates to cases for eyeglasses. More specifically, it relates to cases for multiple pairs of eyeglasses.
BACKGROUND OF THE INVENTION
In recent years, with the general aging of the population, the need for eyeglasses to correct vision defects in people has increased. Research in vision diagnosis and treatment has also indicated that it is sometimes desirable to wear different eyeglasses based on the purpose and situation in which they are to be used. For example, it is now common that separate eyeglasses intended especially for use in viewing a computer screen are prescribed for some individuals, in addition to other pairs of eyeglasses used for other purposes such as driving or reading. Prescription sunglasses, non-prescription sunglasses for use over contact lenses and special prescriptions for use in hobbies and recreational activities all may be employed. The result has been that more persons are wearing multiple pairs of eyeglasses.
Since only one pair of eyeglasses may generally be worn at one time, a user must typically carry the other pairs along wherever they may be needed. Lighter weight glasses are desirable from both a comfort and a style standpoint. Due to the need to make eyeglasses lightweight, the frames of the glasses are often somewhat delicate and may be easily bent or broken. Optimal vision correction performance is not achieved if the lenses are misaligned through bending of the frames. In addition, eyeglasses can have precision optic lenses that degrade in performance if scratched. In particular, antireflective coatings and other high performance coatings tend to be soft and easily damaged through abrasion and exposure to dirt and the like. Further, when glasses are folded, the ends of temples tend to contact the backside of the prescription lenses and scratch them at the point of contact. As a result, it is desirable to protect eyeglasses in some form of case when they are not being worn.
The increase in the number of eyeglass pairs owned by individuals, coupled with the need to protect those glasses has resulted in an increased need for a convenient protective case that is easily carried, and that will hold more than one pair of eyeglasses.
Early attempts at creating a case for multiple pairs of eyeglasses are disclosed in U.S. Pat. No. 683,417 to Weinstein and U.S. Pat. No. 1,004,474 to Schnorr. At the time these cases were invented, however, eyeglasses were often of the pince-nez design that rested on the nose and had no temples extending over the ears of the wearer as commonly used in the eyeglass designs of today. Because these cases were designed to hold two pairs of relatively thin pince-nez glasses stacked directly on top of each other, the overall thickness of the case was not excessive. If such a directly stacked hard-sided design were to be used for eyeglasses having temples, however, the result would be an unsuitably thick and bulky case that was difficult to carry in a shirt or jacket pocket.
Another more recent example of a case for multiple pairs of eyeglasses is disclosed in U.S. Pat. No. 5,676,242 to Scott. The case has compartments for two pairs of glasses, one in a hard-sided compartment and one in an attached soft-sided compartment on top of the hard-sided compartment. This case, however, has a number of disadvantages. First, the soft-sided compartment provides lessened crush protection and possibly inadequate protection for the eyeglasses stored in this compartment. Secondly, snaps and zippers are used to secure the compartments, which can be difficult to manipulate, and cannot be opened with only one hand. Such fasteners may tend to abrade frames or lenses when the glasses are slid into the compartment. Finally, the case has projections, such as the snap secured pocket on one surface and the pocket clip on the opposing surface that make the case unstable when laid on a flat surface, particularly when one or more of the compartments are open.
While existing cases for multiple pairs of eyeglasses have been developed, there remains a need for an eyeglass case that will more effectively accommodate more than one pair of eyeglasses.
SUMMARY OF THE INVENTION
The present invention provides a case for multiple pairs of eyeglasses. The case has a top surface and an opposing bottom surface, a front surface and an opposing back surface and defines a volume for receiving eyeglasses with a length orientation of the eyeglasses substantially parallel to the front of the case. The case is formed from a cover portion and a base portion, hinged together at a pivot line that extends across the bottom of the case parallel to the length orientation of a pair of eyeglasses stored in the case. Preferably, the pivot line is offset on the bottom of the case so as to be closer to the back than the front. The pivot line forms a part of a mating line between the cover portion and the base portion. Preferably, the mating line extends obliquely upward from the bottom, across the ends of the case, and across the top. A divider separates the internal volume of the case into two compartments, each accommodating one pair of eyeglasses. The compartments are offset obliquely, allowing the top-to-bottom dimension of the case to be minimized for easier, more convenient carrying in a jacket or shirt pocket, while still allowing the use of rigid material, providing better protection for the eyeglasses than can be provided in a soft-sided case.
In a preferred embodiment, the hinged connection between the cover portion and the base portion may be provided with a spring for urging the cover and base into a closed position or an open position or both. In addition, detent stops may be provided whereby the case is held in an open or closed position or both. The divider also may be provided with a spring and may be coordinated with the cover and base, so that when the case is opened, the divider assumes a position intermediate of the cover portion and the base portion. The case may also be provided with a latching mechanism for securing the case in a closed position.
The location of the pivot line on the bottom of the case provides a unique advantage, in that when the case is opened, the bottom is articulated into an angled surface. The case can then be placed on any flat surface when opened, and the angled bottom provides a stable base to counterbalance the case from tipping over when opened. The articulation of the case bottom also allows easier, one-handed operation of the case by a user.
Additional objects, advantages, and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In
FIG. 1
, there is shown generally a currently most preferred embodiment of the eyeglass case
100
of the present invention. Case
100
is configured as a rigid, elongate box formed from cover portion
102
and base portion
104
, and has front
108
, back
110
, top
112
, bottom
114
and a pair of opposing ends
116
and
118
. Cover portion
102
and base portion
104
may be made from any suitable material, with the currently preferred materials being metal or rigid plastic preferably covered with a leather or synthetic material. Divider
106
separates the internal volume of case
100
into two compartments
124
and
126
for eyeglasses. Those of skill in the art will recognize that the volume necessary for each compartment
124
and
126
is determined by the length, width and depth orientations of a folded pair of eyeglasses. The length orientation of a pair of eyeglasses is the long dimension across both lenses when the eyeglasses are folded. The width orientation is the dimension perpendicular to the length orientation in a plane formed by the lenses. The depth orientation of a pair of eyeglasses is the dimension orthogonal to the plane formed by the lenses and is the thickness of the pair of eyeglasses when folded. Case
100
, and each compartment
124
and
126
, must accommodate the length orientation of a pair of eyeglasses substantially parallel to front
108
, and must also accommodate the corresponding width and depth orientation of the pair of eyeglasses.
The unique articulation of case
100
is shown in
FIGS. 2-4
. Referring first to
FIG. 2
, which is a view from the bottom of case
100
, cover portion
102
and base portion
104
are hinged together along pivot line
120
on bottom
114
. The hinged attachment between cover portion
102
and base portion
104
may be accomplished with a single lateral hinge
128
as shown, but may also be accomplished with any other type of hinged attachment, including multiple hinges or scored material. Pivot line
120
is substantially parallel with the length orientation of a pair of eyeglasses when stored in case
100
. Pivot line
120
preferably is closer to back
110
than front
108
, and the area of bottom
114
between pivot line
120
and back
110
is smaller than the area of bottom
114
between pivot line
120
and front
108
. Pivot line
120
forms a part of mating line
122
. Mating line
122
is the line where cover portion
102
and base portion
104
are mated together to form case
100
.
As shown in
FIGS. 3 and 4
, mating line
122
extends upward obliquely from bottom
114
across each of ends
116
and
118
and across top
112
. Across top
112
, mating line
122
is parallel with the length orientation of a pair of eyeglasses when they are stored in case
100
. Mating line
122
is closer to front
108
than back
110
, and the area of top
112
between mating line
122
and front
108
is smaller than the area of top
112
between mating line
122
and back
110
.
Referring now to
FIGS. 5 and 6
, the operation of the invention can be understood. When case
100
is closed and cover portion
102
and base portion
104
are mated at mating line
122
, divider
106
separates case
100
into two compartments
124
and
126
, wherein a pair of folded eyeglasses may be stored. The offset orientation of compartments
124
and
126
allows the depth orientation of two pairs of eyeglasses to be accommodated while minimizing the distance between bottom
114
and top
112
. Thus, case
100
has a relatively lower profile, making it easier to fit into a jacket or shirt pocket, while retaining the protective advantages of a rigid, hard-sided case. When case
100
is opened, as shown in
FIG. 6
, compartments
124
and
126
may be accessed to remove the eyeglasses. Divider
106
may be attached to case
100
at pivot line
120
as shown or at any other point within case
100
, and may be provided with a spring and coordinated with cover portion
102
and base portion
104
so that when case
100
is opened, divider
106
moves to a position intermediate of cover portion
102
and base portion
104
to allow better access to the eyeglasses in each of compartments
124
and
126
.
Those of skill in the art will recognize that hinge
128
may be provided with a spring
160
to bias cover portion
102
and base portion
104
toward either or both an open position and a closed position, and further may be provided with detents at either or both of those positions. In the opened position as shown in
FIG. 6
, case may be placed on a flat surface
130
. The offset location of pivot line
120
on bottom
114
allows back
110
to contact flat surface
130
, propping bottom
114
at an angle with respect to flat surface
130
. In this position, bottom
114
is articulated into an angled surface, providing a more stable base than a flat bottom to counterbalance case
100
from tipping over when open.
In addition, the configuration of case
100
is particularly advantageous for operation with one hand. If bottom
114
is placed in the palm of the user's hand with pivot line
120
at the base of the fingers, the user's fingers may be wrapped around back
110
and over top
112
, which is accommodatingly curved. The thumb may be placed on front
108
, and by movement of the fingers, the case may be opened and closed with one hand.
In another preferred embodiment shown in
FIG. 7
, pinion
150
is fixed to the portion of hinge
128
that is rotationally fixed with respect to base portion
104
. Dampener mechanism
152
is fixed to cover portion
102
, and has gear
154
enmeshed with pinion
150
. In operation, when spring
160
urges cover portion
102
toward the open position for case
100
, dampener mechanism
152
acts to retard the relative motion of cover portion
102
and base portion
104
, thereby providing a smooth opening motion for case
100
. Although a pinion arrangement is described, dampener mechanism
152
may be any standard miniature dampener mechanism of pinion, or camming operation or the like, such as for example, those manufactured by NIFCO, Inc. of Japan.
Those of skill in the art will appreciate that case
100
can be provided with a latch so that the case may be securely fastened in a closed position. The latch may be of any type and may be located in any effective location. Currently it is most preferred that the latch be magnetic, and be operable.
Referring again to
FIG. 7
, magnetic latch
170
is of the push-latch type and is provided along mating line
122
in top
112
. Those of skill in the art will recognize that a particularly advantageous mode of operation for case
100
may be achieved when case
100
is closed and placed with bottom
114
resting on a flat surface. In that position, cover portion
102
may be lightly pressed downward toward base portion
104
releasing magnetic latch
170
. Spring
160
urges cover portion
102
upward, opening case
100
. Dampener mechanism
152
provides a retarding force, resisting the bias of the spring, and causing case
100
to smoothly open to the stable open position as described above, and shown in FIG.
6
.
Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of the invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
