Description
THE FIELD OF THE INVENTION
The invention relates to a portable storage and display case and more specifically to a portable case for storing spools of thread or other similarly shaped items.
BACKGROUND OF THE INVENTION
Many crafts, hobbies or professions require organizational equipment to assist in storing and organizing the required tools or accessories. It is often beneficial to provide such organizational equipment in a form that is portable. Carrying cases such as briefcases, tool boxes, and camera bags have been developed to meet these needs. Such carrying cases are also currently being used for carrying fishing tackles, wrenches, or nuts and bolts. However, most such cases do not allow the user to visualize the contents without opening the box and do not provide a mechanism for quick and easy removal of the item from its stored location within the case. A carrying case is also needed for storing and organizing spools of thread, such as a thread case, which is useful to those who sew both recreationally and professionally.
Sewing, which is an art that is centuries old, became an essential skill in the 1800s. As times have changed, sewing has grown as a popular hobby for many. Sewing machines have evolved from large free standing units, typically displayed in the household much like any other furniture, to portable machines that can easily be stored between uses.
Both sewing professionals and recreational sewers typically use numerous spools of threads encompassing a wide variety of colors and types. The number of spools of differing colors used by a sewer can easily exceed 100. Additionally, sewers may also use spools containing thread of various types of thread composition and weight. It is therefore very helpful to keep the spools in an organized fashion, saving time and effort when changing thread colors and/or type during sewing. It is also important that the organizational tool be portable so that it can be easily stored, like the sewing machine, when not in use.
Many attempts have been made to provide a carrying case for spools of thread. These devices include sewing kits and thread boxes in many different configurations. Problems with these cases exist in that it may be difficult to quickly visualize the various colors and types of thread depending on the orientation of the case. Other problems occur if the spools are not easy to remove and quickly accessible when needed. Still other problems occur if the spools easily fall out of the case.
Thus a need exists in the art for a case which allows spools to be organized, stored securely and which allows easy and quick removal of spools for use in professional and recreational sewing.
SUMMARY OF THE INVENTION
The embodiments of the invention overcome the deficiencies in the art by providing a case for storing and displaying thread spools, which allow a user to easily organize the spools. The spools are clearly visible and easily accessible to the user, without falling out of the case.
The various embodiments of the invention provide a storage and display case for holding spools of thread. The case comprises two trays preferably connected by a plurality of hinges. The trays have four walls and an inner surface. A spine is attached to each tray and extends in a first direction. The spine extends from the top inner wall of each tray to the bottom inner wall. Holding pins are attached to the spine and extend in a direction that is generally perpendicular to the spine. The spools are placed on the holding pins for storage and display. A lifting tab is attached to each pin. When the lifting tab is depressed, the corresponding pin is raised, allowing easy access to the desired spool.
The pins are connected to the spine by a U-shaped joint. The U-shaped joint is resilient and retracts when the tab is released. The entire case may be made from a translucent plastic material.
It is therefore an object of the invention to provide a case for storage of thread spools.
It is another object of the invention to provide a case which allows users to organize thread spools.
It is another object of the invention to provide a case for storing thread spools which can be partially opened allowing the user to visualize the stored spools.
It is still another object of the invention to provide a case for thread spools that can be hung from home storage pegs.

shows a storage and display case
10
embodying the invention. The case
10
may be constructed from any material such as plastic so long as it is durable, light, flexible and rigid enough to carry the weight of the stored material. This lightweight construction allows the case, weighing approximately two pounds when empty and approximately four pounds when filled with spools, to be easily portable. The case is also preferably constructed from transparent or translucent material.
The case comprises trays
15
and
16
connected by three hinges
30
. When the case is closed, as shown in
FIG. 1
, the back side of the tray
15
forms a first outer surface
11
and the back side of the tray
16
forms a second outer surface
12
. The hinges
30
are located between a rear outer wall
15

10
and are aligned for engagement. When the case is closed, the brackets engage the pins and, with the application of slight pressure are friction fit to secure the case. The case can be opened by simply lifting the resilient plastic brackets and releasing the pins. It should be understood that any number of latch assemblies may be used for this purpose so long as they are durable, easy to use, and secure the case.
FIGS. 3 and 4
show a spool holding tree
20
of an embodiment of the invention located inside the case. The spool holding tree
20
comprises a plurality of spool holder pins
21
, spool lifting tabs
22
, and a spine
23
. The spine
23
is an elongated member and extends longitudinally inside the case
10
from a top inner wall
16
F of the tray
16
to a bottom inner wall
16
C of the tray
16
. It should be understood that similar spines
23
are located inside tray
15
as well. The spine is preferably molded from the same material as the case. The pins are connected to the spine by a U-shaped joint
24
, and extend laterally away from the spine. Each pin has a corresponding spool lifting tab
22
which extends outwardly from the point where the pin
21
is connected to the U-shaped joint
24
. The spool lifting tabs extend outwardly beyond the plane of the spine. The spine, U-shaped joints, pins, and spool lifting tabs are all preferably molded out of suitable plastic material such as polypropylene and are integrally connected. It should be understood that other suitable materials that are flexible and resilient may also be used.
FIG. 7
shows the interior of the case having a curved trough
57
opposite each pin. The troughs cradle the outer edge of the spools placed on each pin. The pins are oriented at a slight angle towards the interior surface
15
E,
16
E of the case. This provides downward pressure on spools placed on the pins, allowing the outer edge of the spools to be cradled by the troughs.
As shown in
FIG. 2
, each tray has two spines
23
extending longitudinally within the case. The pins extend laterally from the spine in both directions in a first position which is adjacent to the interior surfaces
15
E,
16
E of the trays
15
,
16
. The pins and corresponding spool removal tabs on either side of the spine are preferably not horizontally aligned to facilitate removal and replacement of the spools and accurate labeling as further described below.
A spool
40
, in the form of a cylinder with a hollow center, can be mounted onto the pin
21
to hold the spool
40
securely in place during storage, transport, or display. The dimensions of the holding pins
21
are preferably approximately 1.25 inches in length and 0.25 inches in width such that they will ensure a snug fit between the spool
40
and each holding pin
21
, with the spool exerting a slight compression force on the pin. The force should be sufficient to provide resistance between the inside of the spool
40
and the holding pin
21
preventing the spool
40
from inadvertently sliding off the pin
21
, but not so great as to make it difficult to remove the spool
40
from the pin
21
. The outer edge of the pin which comes in contact with the inner portion of the spool is slightly curved to conform to the curvature of the spool. This provides maximum contact between the spool and pin. It should be understood that the dimensions of the pins may vary depending on the size of the pin or other item to be stored in the case. The case can be opened in any manner, including hanging the open case on hooks or nails by the handle portion, without the spools falling out of the case. In the present embodiment, one spool may be mounted on each pin, allowing the case to hold a plurality of thread spools in a stored position. It should be understood that a plurality of spools may be stored on a single pin, depending on the length of the pin and length of the spools. The spools are stored in a flat position against the inner surfaces
15
E,
16
E of the trays. It may be preferable to arrange the spools according to the colors of the thread, types of thread or numerical sequence of the thread as further described.
Once the spools are mounted on the pins within the case, the spool lifting tabs
22
can be used to lift each individual spool
40
from its stored position when removing the desired spool
40
for use. The lifting is accomplished by applying pressure on the tab
22
corresponding to the desired spool, typically with one's thumb or finger, in a direction away from the stored spool and towards the spine. It should be understood that the spool lifting tab is preferably longer than the radius of the base of the thread spool cylinder. This allows the user to more easily depress the tab in order to lift the spool. The desired spool can then be removed from the pin by simply sliding the spool off the pin. The resiliency of the material used to form the U-shaped joint and the remainder of the tree causes the pin to automatically return to its initial position, adjacent the interior surfaces
15
E,
16
E, once the tab is released.
Each pin
21
and associated tab
22
assembly, as shown in
FIG. 3
are attached to the spine
20
such that they are offset or staggered an appropriate distance
25
B, preferably approximately ½ inches, from the center of the corresponding pin
21
A and tab
22
A assembly located on the opposite side of the spine
23
. Such staggering facilitates the removal of each individual spool
40
from its stored position by allowing easy access to the spool lifting tab associated with the desired spool. The staggering of the tabs prevents users from inadvertently depressing the wrong tab, making the case easier to use. The staggering also allows users to associate labels with each thread spool. To aid in the symmetry beneficial for storage it is preferred that the distance
25
B between opposing pin and tab assemblies be approximately half the distance
25
A between two adjacent pin and tab assemblies. However, it should be understood that any offset distance can be used so long as the spools
40
may be lifted by depressing the tab
22
without interference from the tab
22
A located on the opposite side of the spine
23
.
The spine
23
of the spool tree
20
in
FIGS. 3
,
4
preferably should be wide enough to accommodate a marking strip that can be used to identify each individual spool by such characteristics as thread color, thread type, thread number or thickness. Spools of thread may be associated with a number for identification purposes. Each number corresponds to a color, weight, and type of thread. The marking strip, or labels placed on the spine may indicate the spool number next to each peg. The user may place the spool with corresponding number on the identified peg to organize the spools within the case.
Embodiments of the invention have been described with particular reference to the function of carrying spools of thread, however such a storage and display case can also be used to carry such items as photography film, spools of electrical wire, fishing tackles, jewelry, and any other item of similar size and shape.
While the invention has been described in detail with particular reference to preferred embodiments thereof, it will be understood that variations and modifications can be effected within the spirit and scope of the invention as described hereinbefore and as defined in the appended claims.
