Shock absorbing device for surfboard and bags

Abstract

A board for water sport gears includes an elongate body and a shock absorbing device is attached on a top surface of the board. The device includes a plurality of ribs and a plurality of walls are connected between the first ribs so as to define a plurality of chambers between the ribs and the walls. An upper layer and a bottom layer are respectively connected to two opposite sides of the device. The ribs and the walls are made by resilient material so that it can be deformed to absorb shocks. The device can also be connected between inner and outer layers of bags to protect the contents in the bags.

1 . A board for water sport gears comprising: 
 an elongate body having a front end and a rear end;    a shock absorbing device attached on a top surface of the board, the device including a plurality of first ribs and a plurality of first walls connected between the first ribs so as to define a plurality of first chambers between the first ribs and the first walls.    
   
   
       2 . The board as claimed in  claim 1 , wherein the first ribs and the first walls are arranged to define polygonal-shaped first chambers.  
   
   
       3 . The board as claimed in  claim 1 , wherein the shock absorbing device is located at one third of the length of the elongate body from the rear end.  
   
   
       4 . The board as claimed in  claim 1 , wherein the shock absorbing device includes an upper layer and a bottom layer, the first chambers are enclosed between the upper layer and a bottom layer.  
   
   
       5 . The board as claimed in  claim 1 , wherein a friction pad is attached on the shock absorbing device and a plurality of bosses extend from a top of the friction pad.  
   
   
       6 . The board as claimed in  claim 1 , wherein the shock absorbing device includes a plurality of second ribs and second walls, a plurality of chambers are defined between the second ribs and the second walls, the second ribs and second walls are located beneath the first ribs and the first walls and are arranged alternatively to the first ribs and the first walls.  
   
   
       7 . The board as claimed in  claim 1 , wherein the first and second ribs and the first and second walls are made by TPU or TPE.  
   
   
       8 . A bag comprising: 
 a body composed of an inner layer and an outer layer which is connected to the inner layer, an opening defined in the body between the inner layer and the outer layer, and    a shock absorbing device sandwiched between the inner layer and an outer layer, the shock absorbing device including a plurality of ribs and a plurality of walls which are connected between the ribs so as to define a plurality of chambers between the ribs and the walls.    
   
   
       9 . The bag as claimed in  claim 8 , wherein the ribs and the walls are arranged to define polygonal-shaped first chambers.  
   
   
       10 . The bag as claimed in  claim 1 , wherein the ribs and the walls are made by TPU or TPE.
