INTEGRATED WATCH BAND AND METHODS THEREFOR
The present invention includes an integrated (composite) watchband and process for making a watchband that integrates a high tensile strength fabric (e.g. an aramid fabric) within the watchband via an injection molding process. The resultant integrated watchband exhibits greatly increased strength while maintaining all the necessary characteristics of a conventional band.
1 . An integrated band comprising:
a polymer resin; and
a high tensile strength fabric;
wherein the high tensile strength fabric is integrally bonded within the polymer resin to form the integrated band.
2 . The integrated band according to claim 1 , wherein the high tensile strength fabric comprises a preformed narrow woven strip of aramid fabric.
3 . The integrated band according to claim 1 , wherein the polymer resin comprises a thermoplastic elastomer.
4 . The integrated band according to claim 1 , wherein the polymer resin comprises a melt processable rubber.
5 . The integrated band according to claim 1 , wherein a thickness of the high tensile strength fabric is uniform.
6 . The integrated band according to claim 1 , wherein a thickness of the high tensile strength fabric is increased in at least one portion of the integrated band.
7 . The integrated band according to claim 1 , wherein the high tensile strength fabric extends less than ⅓ of a total length of the integrated band.
8 . The integrated band according to claim 1 , wherein the high tensile strength fabric extends at least ⅓ of a total length of the integrated band.
9 . The integrated band according to claim 1 , wherein the integrated band has a tensile strength of at least 2000 pounds per square inch.
10 . A method of forming an integrated band comprising:
providing a high tensile strength fabric within a mold;
injecting a polymer resin about the high tensile strength fabric; and
curing the polymer resin and the high tensile strength fabric mixture;
wherein the high tensile strength fabric is integrally bonded within the polymer resin via the curing.
11 . The method according to claim 10 , wherein the high tensile strength fabric comprises a preformed narrow woven strip of aramid fabric.
12 . The method according to claim 10 , wherein the polymer resin comprises a thermoplastic elastomer.
13 . The method according to claim 10 , wherein the polymer resin comprises a melt processable rubber.
14 . The method according to claim 10 , wherein a thickness of the high tensile strength fabric is uniform.
15 . The method according to claim 10 , wherein a thickness of the high tensile strength fabric is increased in at least one portion of the integrated band.
16 . The method according to claim 10 , wherein the high tensile strength fabric extends less than ⅓ of a total length of the integrated band.
17 . The method according to claim 10 , wherein the high tensile strength fabric extends at least ⅓ of a total length of the integrated band.
18 . The method according to claim 10 , wherein the integrated band has a tensile strength of at least 2000 pounds per square inch.
19 . A watch comprising:
a watch case portion; and
at least one integrated band portion comprising:
a pin and hinge portion;
a polymer resin; and
a high tensile strength fabric;
wherein the high tensile strength fabric is integrally bonded within the polymer resin; and
wherein the polymer resin is molded about the pin and hinge portion to provide secure connection between the at least one integrated band portion and the watch case portion.
