Pocket spring structure for bed mattress

Abstract

Disclosed herein is a pocket spring structure for a bed mattress, in which a rigid support capable of resisting compressive strength due to applied load is further integrally formed in a partial region of a spring mounted in a sealed pocket, thereby preventing deformation of the spring and increasing its durability. That is, the present invention provides a pocket spring structure for a bed mattress, in which a separate rigid support capable of resisting compressive strength due to applied load is integrally formed in a partial region of a spring mounted in a pocket formed of fabric to prevent deformation of the spring, even when large and small loads are irregularly and repeatedly concentrated on the spring, thereby increasing its durability and further improving the quality of the bed mattress.

         6 . The pocket spring structure of  claim 1 , wherein the rigid support comprises:
 a first rigid support integrally formed at an uppermost wiring of the body spring connected to the upper end spring in such a manner that the first rigid support is vertically arranged, and   a second rigid support integrally formed at a lowermost wiring of the body spring connected to the lower end spring in such a manner that the second rigid support is vertically arranged.   
     
     
         7 . The pocket spring structure of  claim 1 , wherein the rigid support comprises;
 a first rigid support integrally formed at an uppermost wiring of the body spring connected to the upper end spring in such a manner that upper and lower ends of the first rigid support are bent and inclined at an obtuse or acute angle, and   a second rigid support integrally formed at a lowermost wiring of the body spring connected to the lower end spring in such a manner that upper and lower ends of the second rigid support are bent and inclined at an obtuse or acute angle.   
     
     
         8 . The pocket spring structure of  claim 1 , wherein the rigid support is integrally formed at an intermediate wiring of the body spring in such a manner that the rigid support is vertically arranged. 
     
     
         9 . The pocket spring structure of  claim 1 , wherein the rigid support is integrally formed at an intermediate wiring of the body spring in such a manner that upper and lower ends of the rigid support are bent and inclined at an obtuse or acute angle. 
     
     
         10 . The pocket spring structure of  claim 1 , wherein the rigid support is integrally formed only in a region where an intermediate wiring and an uppermost wiring of the body spring are connected to each other in such a manner that the rigid support is vertically arranged. 
     
     
         11 . The pocket spring structure of  claim 1 , wherein the rigid support is integrally formed only in a region where an intermediate wiring and an uppermost wiring of the body spring are connected to each other in such a manner that upper and lower ends of the rigid support are bent and inclined at an obtuse or acute angle. 
     
     
         12 . The pocket spring structure of  claim 1 , wherein the rigid support is integrally formed only in a region where an intermediate wiring and a lowermost wiring of the body spring are connected to each other in such a manner that the rigid support is vertically arranged. 
     
     
         13 . The pocket spring structure of  claim 1 , wherein the rigid support is integrally formed only in a region where an intermediate wiring and a lowermost wiring of the body spring are connected to each other in such a manner that upper and lower ends of the rigid support are bent and inclined at an obtuse or acute angle. 
     
     
         14 . The pocket spring structure of  claim 1 , wherein the rigid support comprises:
 a first rigid support integrally formed in a region where an intermediate wiring and an uppermost wiring of the body spring are connected to each other in such a manner that the first rigid support is vertically arranged, and   a second rigid support integrally formed in a region where the intermediate wiring and a lowermost wiring of the body spring are connected to each other in such a manner that the second rigid support is vertically arranged.   
     
     
         15 . The pocket spring structure of  claim 1 , wherein the rigid support comprises:
 a first rigid support integrally formed in a region where an intermediate wiring and an uppermost wiring of the body spring are connected to each other in such a manner that upper and lower ends of the first rigid support are bent and inclined at an obtuse or acute angle, and   a second rigid support integrally formed in a region where the intermediate wiring and a lowermost wiring of the body spring are connected to each other in such a manner that upper and lower ends of the second rigid support are bent and inclined at an obtuse or acute angle.
