Waterproof and portable strap for carrying small-type portable electronic device

Abstract

A waterproof and portable strap comprises a hanging strap and a holding means for carrying a small-type portable electronic device. The hanging strap has coupling heads on both sides, wherein the coupling heads have openings and closed trenches, and the closed trenches have several coupling parts. The closed trench of one coupling head has a taper surface. The holding means is a casing having a receiving trench and a closed surface on both sides for protecting the electronic device and stretching out a terminal portion, wherein the holding means has several coupling parts for coupling with the coupling parts of one closed trench of one coupling head, and the holding means has an exposed outer surface for insertion into the other closed trench of the other coupling head. The holding means has several retaining parts corresponding to the other coupling parts of the other closed trench.

       5 . A waterproof and portable strap for carrying a small-type portable electronic device of  claim 3 , wherein said retaining parts of said holding means are convex structures to engage with said second coupling parts of said second coupling head. 
   
   
       6 . A waterproof and portable strap for carrying a small-type portable electronic device of  claim 1 , wherein said first coupling parts of said first coupling head are convex structures. 
   
   
       7 . A waterproof and portable strap for carrying a small-type portable electronic device of  claim 6 , wherein said third coupling parts of said holding means are concave structures to engage with said first coupling parts of said first coupling head. 
   
   
       8 . A waterproof and portable strap for carrying a small-type portable electronic device of  claim 6 , wherein said retaining parts of said holding means are concave structures to engage with said second coupling parts of said second coupling head. 
   
   
       9 . A waterproof and portable strap for carrying a small-type portable electronic device of  claim 1 , wherein said taper surface has a caliber, which is exactly fit for said terminal portion of said small-type portable electronic device, and said terminal portion is exposed to the outside of said holding means such that said terminal portion can be tightly inserted into said taper surface. 
   
   
       10 . A waterproof and portable strap for carrying a small-type portable electronic device comprising:
 a hanging strap having a first and a second coupling heads on both sides respectively, wherein said first and said second coupling heads have a first and a second openings and a first and a second closed trenches, and said first and said second closed trenches have a plurality of first and second coupling parts surrounding respective traverse walls entirely, wherein said closed trench of said second coupling head has a taper surface on a rear wall; and   a holding means being a casing having a receiving trench on one side and a closed surface on the other side so as to allow said small-type portable electronic device to be inserted into said receiving trench for protecting a main body of said small-type portable electronic device and stretching out a terminal portion of said small-type portable electronic device, wherein said holding means has a plurality of third coupling parts for coupling with said first coupling parts of said first closed trench of said first coupling head, wherein each of said third coupling parts has a right-angled blocking surface and a guide surface formed on the top of said blocking surface, and said holding means has an outer surface that exposes to the outside of said first closed trench for insertion into said second closed trench of said second coupling head, wherein said holding means has a plurality of retaining parts corresponding to said second coupling parts of said second closed trench, whereby said third coupling parts of said holding means can be coupled with said first coupling parts of said first closed trench of said first coupling head of said hanging strap, and said second coupling parts of said second closed trench of said second coupling head can be coupled with said retaining parts of said holding means so as to allow said waterproof and portable strap to be wound around the user's hand.   
   
   
       11 . A waterproof and portable strap for carrying a small-type portable electronic device of  claim 10 , wherein said hanging strap is made of a flexible material. 
   
   
       12 . A waterproof and portable strap for carrying a small-type portable electronic device of  claim 10 , wherein said first coupling parts of said first coupling head are concave structures.
