## Title
Detachable wrist coach

## Abstract

A detachable wrist coach has a detachable sheet of football plays in a transparent pocket joined to a sweatband by hook-and-loop fasteners. The detachable sheet can be separated from the sweatband so that the sweatband can be cleaned without degrading the transparent pocket or getting water into it. One or more flaps with transparent pockets can be attached to the detachable sheet by a hinge that multiple pages of plays may be viewed by opening the flap. The flap is held down by a second hook-and-loop fasteners with a lower peel strength than the sweatband's hook and loop fasteners so that a top flap can be opened without removing the detachable sheet from the sweatband.

## Background
CROSS REFERENCE TO RELATED APPLICATION
This patent application claims the benefit of US provisional patent application “Wearable armband with detachable pocket windows used in sports to hold play cards also known as a wrist coach”, by Joseph King and Kyle D. Rothschild, U.S. Ser. No. 61/962,700, filed Nov. 15, 2013. Said application is incorporated herein in its entirety by reference.


COPYRIGHT AND TRADEMARK NOTICE
A portion of the disclosure of this patent document contains material to which a claim for copyright is made. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but reserves all other copyright rights whatsoever.
BACKGROUND OF THE INVENTION
FIG. 1 displays a sports wristband 100 based on US patent application US2011/0167536, “Sports Wristband with Layered Transparent Pockets” (Kellerhals). Said wristband comprises a sweatband 102, a transparent pocket 104, and a transparent pocket flap 106. The transparent pocket is fixedly joined to the sweatband. The transparent pocket flap is hingedly joined 112 to the transparent pocket. Said flap comprises layered transparent windows 114 and a first sheet fastening portion 116. Said sweatband comprises a second sheet fastening portion 118 which corresponds to said first sheet fastening portion on said flap. Thus said flap can be reversibly closed and opened depending upon if the user does or does not want visual access to said first transparent pocket and/or the bottom of said second transparent pocket. Said sheet fastening portions may comprise Velcro® hook and loop joining cloth. Velcro® is a registered trademark of Velcro Industries B. V.
Sweatbands similar to Kellerhals' have been used in American football to hold and display cards with different plays imprinted upon them. A “play” is a planned series of movements by the members of a team. The leader of the team, the Quarterback, may consult said wristband and instruct the other members of the team on which play is to be executed next. Sweatbands used in this manner are termed “wrist coaches”.
American football is a vigorous sport that is often played outdoors and in rainy weather. Thus the sweatbands on wrist coaches can become quite soiled and require frequent cleaning. Unfortunately, the transparent pockets on said wrist coaches are degraded by normal washing. The transparent plastic films of said pockets may become cloudy 122 or may trap water 124 after washing. Thus wrist coaches only last for a few wash cycles and must be replaced frequently. If wrist coaches are not washed frequently, then the soiled sweatbands can become sources of infection.
SUMMARY OF THE INVENTION
The summary of the invention is provided as a guide to understanding the invention. It does not necessarily describe the most generic embodiment of the invention. The inventions described herein may be used in any sport or any activity where a user wishes to have a detachable sheet mounted on a sweatband. It may be used, for example, in construction or military applications. The sweatband may be mounted on any appropriate body part, such as a wrist or ankle.

DETAILED DESCRIPTION
The detailed description describes non-limiting exemplary embodiments. Any individual features may be combined with other features as required by different applications for at least the benefits described herein. As used herein, the term “about” means plus or minus 10% of a given value unless specifically indicated otherwise.
Wrist Coach with Recessed Fastening Portions
FIG. 4A shows a detachable wrist coach 400 comprising a sweatband 404 and a detachable sheet 402 shown just above it. The construction is similar to the detachable wrist coach 320 of FIG. 3C. The sweatband in this case has at least the same thickness 406 as the first sheet fastening portions 408. Furthermore, said first sheet fastening portion may be recessed within said sweatband such that the top of the first sheet fastening portion 412 is below or flush with the top of said sweatband 414. Thus the detachable sheet 402 will lay flat on said sweatband 404 when joined to said sweatband as shown in FIG. 4B.
Wrist Coach with Flap
FIGS. 5A through 5D illustrate an alternative detachable wrist coach were the detachable sheet comprises a flap. FIG. 5A shows the top of a detachable sheet 500. The detachable sheet comprises a pocket with a transparent window 502 for viewing a sheet of paper retained therein. The detachable sheet further comprises a first flap fastening portion 504 mounted on a frame 506. The frame may be a flexible material, such as a vinyl sheet. The items may be held together by stitching, gluing or other suitable joining means.
FIG. 5B shows the bottom of a flap 510. Said flap is to be hingedly joined to said sheet. Said flap comprises back-to-back transparent windows 512, 514 held together in a frame 516 to form a flap pocket. Said flap pocket is transparent therethrough so that sheets held therein can be viewed from one side or the other. Said flap comprises a second flap fastening portion 518 that corresponds to said first flap fastening portion.
FIG. 5C shows a detachable wrist coach 520 comprising a sweatband 302, a detachable sheet 500 and a flap 510. The detachable sheet is shown above the sweatband. The flap and detachable sheet are joined together by a hinge 526 and said flap fastening portions 504, 518.
FIG. 5D shows the detachable wrist coach 520 of FIG. 5C with the detachable sheet 500 attached to the sweatband 302 and the flap 510 open. In order for the user to open the flap without removing detachable sheet from the sweatband, the peel strength of the flap fastening portions should be less than the peel strength of the sheet fastening portions. This can be accomplished by having the flap fastening portions have a more narrow width 522 than the width 524 of a sheet fastening portion. The flap fastening portion may also have a smaller area than the sheet fastening portion. The unit peel strength of the flap fastening portions can also be less than the unit peel strength of the sheet fastening portion. Unit peel strength may be expressed as Newtons/cm.
Wrist Coach with Two Flaps
FIGS. 6A through 6D illustrate an alternative detachable wrist coach which comprises two flaps. FIG. 6A shows the top of a first flap 600. Said first flap is similar in construction to the flap 510 of FIG. 5B. The top of said first flap comprises back-to-back transparent windows 604 to form a pocket for holding sheets indicating plays therein and a frame 606. The frame, however, additionally comprises a first top flap fastening portions 608.
FIG. 6B shows the bottom of a second flap 610. Said second flap is similar in construction to said first flap with second top flap fastening portions 612. The width 614 of said top flap fastening portions is less than the width of the flap fastening portions 504, 518 (FIG. 5C) so that the peel strength of the second flap from the first flap will be less than the peel strength of the first flap from the detachable sheet. Hence a user can independently open the first flap and the second flap.
FIG. 6C shows a detachable wrist coach 620 with a detachable sheet 500, a first flap 600 and a second flap 610 all positioned above a sweatband 302. The second flap is joined to the first flap with a second hinge 622 and said top flap fastening portions 608, 612.

FIG. 6D shows the detachable wrist coach 620 of FIG. 6C with the detachable sheet 500 attached to the sweatband 302 and the top flap 610 open.
Wrist Coach with Flush Top Leaf
FIG. 7A illustrates a wrist coach 700 with a deeply recessed chamber 712 in the sweatband 710. The depth 714 of the recess is about the same as the depth 704 of the detachable sheet and any flaps 702 that are placed in it. Thus as shown in FIG. 7B, when a detachable sheet and flap are placed in the recess, the top surface 722 of the flap is about flush with the top surface 724 of the sweatband. The thickness of the sweatband 715 (FIG. 7A) does not have to be uniform. It could be narrower, for example, in the back.
FIG. 7A also illustrates a laterally conformable hinge 703. This might be a flexible piece of cloth. Referring to FIG. 7B, the laterally conformable hinge can shift when the leaf and detachable sheet are bent so that the flap fastening portions 732 can remain aligned.
FIG. 7A also illustrates a first fold-over fastening portion 716 and a second fold-over fastening portion 706. The first fold-over fastening portion comprises a hinge 718, such a flexible section of cloth. It may also simply be a folded portion of the loop fabric of a hook-and-loop fastening cloth. The second fold-over fastening portion also comprises a hinge 708. This might also be a cloth. The second fold-over fastening portion comprises two sides, each of which can join to the first fold-over fastening portion. This might be two pieces of the hook fabric of a hook-and-loop fastening cloth. Referring to FIG. 7B, when the detachable wrist coach is assembled 720, the second portion folds over the first portion to form a sandwich structure 726 which is particularly resistant to be pulled off, but can be relatively easily opened and peeled off by a user.
FIG. 7A also illustrates a tab 705 placed on the flap. Referring to FIG. 7B, the tab may extend over the sweatband to assist a user in peeling open the flap to view the detachable sheet below.
FIG. 8 illustrates the wrist coach 700 of FIGS. 7A and 7B mounted on a user's arm 802. The sweatband 804 has a recessed portion 806 and first sheet joining portions attached at the bottom thereof. A first fold-over joining portion 808 and second fold-over joining portion 814 are provided. When mounted with said recess, the top of the leaf 812 will be about flush with the top of the sweatband.
Wrist Coach with Lay-Flat Detachable Sheet
FIG. 9A illustrates a sweatband 904 mounted on a user's arm 902 with recessed portions 906 for the first sheet fastening portions. Referring to FIG. 9B, the first sheet fastening portions 912 fit into said recesses such that the detachable sheet 914 lays flat on top of the sweatband. This provides a very comfortable fit to the user.
Example
A detachable wrist coach was made according to the design described in FIGS. 3A to 3D and 5A to 5D. The sweatband 302 was made of a smooth cotton/spandex material. When unstretched, it had a uniform circumference of about 20 cm and a length of about 13 cm. When it was fully stretched, the circumference was about 28 cm. The sheet fastening portions 304, 305, 306, 312, 313, and 314 were three Velcro strips. Each strip was about 2 cm wide by about 12.5 cm long. The spacing between the Velcro strips was about 1 cm. The window 502 in the detachable sheet had a width of about 7 cm and a length of about 12 cm. The windows 512 and 514 in the flap were similarly dimensioned. The flap fastening portions 504 and 518 were Velcro strips. The Velcro strips were about 1 cm wide by 12 cm long.
The detachable wrist coach was worn by a user during an American football practice. The detachable sheet stayed on during practice and said Quarterback could open and close said flap without said detachable sheet coming off the sweatband. After the practice, the sweatband was detached from the sheet and washed. The detachable sheet and flap were wiped clean without the transparent pockets becoming cloudy or water getting trapped between them.
Alternative Embodiments
The sheet fastening portions can be any joining method that is attachable and detachable by hand. Sheet fastening portions, for example, may be snaps, sticky tape, magnetic closures, buttons, interlocking plastic closure strips, such as those found on Ziploc® food storage bags. Ziploc is a registered trademark of S. C. Johnson & Son, Inc. For sheet fastening portions that are either fully closed or fully open, such as snaps, the opening force as opposed to peel strength is the appropriate design parameter to allow, for example, the opening of a flap without removal of a detachable sheet from a sweatband.
