Golf club protective cover

Abstract

A golf club protective cover is proposed which can protect golf clubs in a golf bag and the hood of the golf bag from damage resulting from e.g. rough handling of the golf bag or the fall of the golf bag. The cover includes an outer bag having a single opening and an inner bag having a single opening and inserted in the outer bag. The edges defining the openings of the outer and inner edges are fused together to define a hermetically sealed air chamber between the outer and inner bags. Either of the outer and inner bags is formed of a flexible, airtight sheet. The outer bag has an air valve through which air can be introduced into and discharged from the air chamber.

What is claimed is:  
     
         1 . A golf club protective cover. comprising an outer bag having a single opening, and an inner bag having a single opening and inserted in said outer bag with its edge defining said opening fused to the edge of said outer bag defining said opening to define a hermetically sealed air chamber between said outer bag and said inner bag, said outer and inner bags being formed of a flexible, airtight sheet, said outer bag having an air valve through which air can be introduced into and discharged from said air chamber.  
     
     
         2 . The golf club protective cover as claimed in  claim 1  wherein said outer bag and said inner bag are formed by putting one sheet for said outer bag on another sheet for said inner bag with all sides aligned with each other, folding them in two with the sheet for said outer bag outside, fusing together the side edges (four) of the two sheets at both sides, and fusing together the end edges of the two sheets at two positions separately to form a hermetically sealed air chamber.
