Diving Backplate

Abstract

A diving backplate includes a device body, a first frame, a second frame and multiple counterweights. The device body includes an inward face and an outward face opposite to the inward face. The first frame is connected to the outward face. The second frame is connected to the inward face and includes multiple first assembly holes. The multiple counterweights are detachable mounted to the second frame. Each counterweight includes multiple second assembly holes each respectively aligned with a respective one of the multiple first assembly holes. A fastener is provided for mounting with each aligned first assembly hole and second assembly hole.

What is claimed is: 
     
         1 . A diving backplate, comprising:
 a device body including an inward face and an outward face opposite to the inward face;   a first frame connected to the outward face;   a second frame connected to the inward face and including multiple first assembly holes; and   multiple counterweights detachable mounted to the second frame, wherein each counterweight includes multiple second assembly holes each respectively aligned with a respective one of the multiple first assembly holes, and wherein a fastener is provided for mounting with each aligned first assembly hole and second assembly hole.   
     
     
         2 . The diving backplate as claimed in  claim 1 , wherein the second frame includes a base and two side walls respectively connected to two sides of the base, and wherein the multiple first assembly holes are located on the two side walls. 
     
     
         3 . The diving backplate as claimed in  claim 2 , wherein the base and the two side walls are integrally formed. 
     
     
         4 . The diving backplate as claimed in  claim 1 , wherein the first frame includes multiple adjusting holes each configured to be mounted with an adjusting member, and wherein one end of the adjusting member abuts the outward face of the device body. 
     
     
         5 . The diving backplate as claimed in  claim 1 , wherein the first frame includes multiple first position holes each configured to be mounted with a positioning member. 
     
     
         6 . The diving backplate as claimed in  claim 5 , wherein the second frame includes multiple second positioning holes, and wherein each of the positioning members extends through the device body to be mounted with a respective one of the second positioning holes. 
     
     
         7 . The diving backplate as claimed in  claim 6 , wherein each of the counterweights includes a third positioning hole and a positioning plug, wherein each of the third positioning holes aligns with a respective one of the first position holes and a respective one of the second positioning holes, and wherein each of the positioning plugs seals a respective one of the third positioning holes. 
     
     
         8 . The diving backplate as claimed in  claim 7 , wherein each of the positioning plug includes an internal threaded hole and a recess, wherein the internal threaded hole is configured to be mounted with a respective one of the fasteners, and wherein the recess is arranged away from the second frame than the internal threaded hole. 
     
     
         9 . The diving backplate as claimed in  claim 1 , further comprising a strap extending through the multiple counterweights and forming a handle strap portion. 
     
     
         10 . The diving backplate as claimed in  claim 9 , wherein the strap includes a shoulder strap portion and waist strap portion, and wherein the handle strap portion, the shoulder strap portion and the waist strap portion are integrally formed.
