Elastic mattress

Abstract

An elastic mattress has a base layer, a plurality of elastic modules and a pad layer. The elastic modules are detachably arranged on a second surface of the base layer and are configured to directly contact the ground. The pad layer is arranged on a first surface of the base layer. Since the plurality of elastic modules are arranged on the second surface of the base layer and can directly contact the ground, the number of components of the elastic mattress is reduced and the structure simplified lowering the cost of the elastic mattress, while providing high comfort. Moreover, as the pad layer can be removed from the first surface of the base layer, the elastic mattress can be more easily moved and stored.

1 . An elastic mattress, comprising:
 a base layer ( 3 ) comprising a first surface ( 1 ) and a second surface ( 2 ) opposite to each other in a height direction of the elastic mattress;   a plurality of elastic modules ( 4 ) detachably arranged on the second surface ( 2 ) and being configured to directly contact the ground; and   a pad layer ( 5 ) arranged on the first surface ( 1 );   wherein no side enclosures are provided at the periphery of the elastic mattress, thereby forming an elastic mattress with fully open sides.   
     
     
         2 . The elastic mattress of  claim 1 , wherein the pad layer ( 5 ) and the base layer ( 3 ) are connected via a connecting structure arranged therebetween. 
     
     
         3 . The elastic mattress of  claim 2 , wherein the connecting structure is a hook-and-loop fastener ( 6 ) arranged on the first surface ( 1 ) of the base layer ( 3 ) and/or a lower surface of the pad layer ( 5 ). 
     
     
         4 . The elastic mattress of  claim 1 , wherein the pad layer ( 5 ) is a foldable or rollable pad layer. 
     
     
         5 . The elastic mattress of  claim 4 , wherein the pad layer ( 5 ) comprises a plurality of elastic pad blocks ( 7 ) arranged in a length direction of the elastic mattress, and the elastic pad blocks ( 7 ) adjacent to each other are connected via a flexible portion. 
     
     
         6 . The elastic mattress of  claim 5 , wherein the flexible portion comprises grooves ( 9 ) formed on an upper surface ( 8 ) and/or a lower surface of the pad layer ( 5 ) and extending along a width direction of the elastic mattress. 
     
     
         7 . The elastic mattress of  claim 1 , wherein the base layer ( 3 ) is a flexible base layer, and the plurality of elastic modules ( 4 ) can be removed from the second surface ( 2 ) and then nested together. 
     
     
         8 . The elastic mattress of  claim 1 , wherein the second surface ( 2 ) of the base layer ( 3 ) is provided with a plurality of positioning rails ( 10 ) that are spaced apart in a length direction of the elastic mattress, each of the positioning rails ( 10 ) extending along a width direction of the elastic mattress, and an installation zone ( 11 ) for receiving the elastic modules is formed between the positioning rails ( 10 ) adjacent to each other, and wherein each of the elastic modules ( 4 ) is configured to be slidable in the width direction of the elastic mattress from either one end of the adjacent positioning rails ( 10 ) onto the adjacent positioning rails ( 10 ), and then slide in place along the positioning rails ( 10 ), such that each of the installation zones ( 11 ) are arranged with the plurality of elastic modules ( 4 ). 
     
     
         9 . The elastic mattress of  claim 8 , wherein an outer edge of the second surface ( 2 ) is disposed with stop edges ( 12 ) extending a predetermined height in the height direction of the elastic mattress, and the plurality of the positioning rails ( 10 ) are located between the stop edges ( 12 ), so that the elastic modules ( 4 ) are kept in position by the stop edges in the width direction of the elastic mattress. 
     
     
         10 . The elastic mattress of  claim 9 , wherein the stop edge ( 12 ) is a rectangular stop edge extending along a periphery of the outer edge of the second surface ( 2 ), and wherein the rectangular stop edge is a flexible body and is kept a predetermined distance away from an outer peripheral surface of the base layer ( 3 ).
