Elastic module balance cushion, elastic cushion, and furniture

Abstract

A balancing pad for furniture includes a base plate and a plurality of spaced apart limit bosses forming receiving spaces configured to receive corresponding elastic modules of an elastic base pad. The balancing pad constrains movement of the elastic modules in a transverse direction. When assembled to form the elastic pad, the balancing pad may be laid on the elastic base pad and a portion of the elastic modules may be received in respective receiving spaces. Constraining movement of the elastic modules improves the stability of the elastic pad, providing better comfort.

         18 . A furniture balancing pad, comprising:
 a base plate and a plurality of limit bosses spaced apart from each other on and protruding from a surface of the base plate, the plurality of limit bosses forming a plurality of receiving spaces spaced apart from each other, each receiving space configured to receive a corresponding elastic module of an elastic base pad, to constrain movement of the corresponding elastic modules in a transverse direction of the base plate.   
     
     
         19 . The balancing pad of  claim 18  wherein a cross-sectional size of each of the plurality of limit bosses tapers down in a direction away from the base plate so that an inner size of the receiving space decreases towards the base plate. 
     
     
         20 . The balancing pad of  claim 19  wherein each of the plurality of limit bosses is formed as a truncated body. 
     
     
         21 . The balancing pad of  claim 18  wherein the based plate comprises a flexible material. 
     
     
         22 . The balancing pad of  claim 18  wherein each of the plurality of limit bosses is made of elastic material and formed as an elastic body. 
     
     
         23 . The balancing pad of  claim 22  wherein the elastic body comprises a flexible outer sleeve and an elastic member, the elastic member disposed within the flexible outer sleeve, wherein one end of the flexible outer sleeve is connected to the base plate, and the other end of the flexible outer sleeve extends away from the base plate. 
     
     
         24 . The balancing pad of  claim 23  wherein the flexible outer sleeve and the base plate are formed from the same material. 
     
     
         25 . The balancing pad of  claim 24  wherein the flexible outer sleeve is a nonwoven fabric sleeve, and the base plate is a nonwoven fabric plate. 
     
     
         26 . The balancing pad of  claim 23  wherein one end of the elastic member is connected to the surface of the base plate, and the other end of the elastic member is connected to an end cap at an end of the flexible outer sleeve so that the elastic member is in a pre-compressed state. 
     
     
         27 . The balancing pad of  claim 23  wherein an outer peripheral profile of the elastic member is pressed against an inner peripheral surface of the flexible outer sleeve. 
     
     
         28 . The balancing pad of  claim 23  wherein the elastic member comprises a spring. 
     
     
         29 . The balancing pad of  claim 18  wherein the plurality of limit bosses comprise a plurality of first limit bosses and a plurality of second limit bosses, wherein each of the receiving spaces is surrounded by the plurality of first limit bosses and the plurality of second limit bosses arranged alternately in sequence, wherein each of the first limit bosses is surrounded by the second limit bosses of surrounding multiple receiving spaces. 
     
     
         30 . The balancing pad of  claim 29  wherein a plurality of first-row limit bosses and second-row limit bosses arranged alternately in sequence are provided on a plate surface on one side of the base plate, wherein:
 each row of the first-row limit bosses comprises a plurality of first limit bosses and second limit bosses adjacent alternately in sequence in a row direction; 
 each row of the second-row limit bosses comprises a plurality of second limit bosses arranged apart from each other at an interval in the row direction, the interval being one said second limit boss; 
 wherein each said second limit boss in each row of said second-row limit bosses is aligned with each said first limit boss of an adjacent row in a column wise direction such that the interval serves as the receiving space. 
 
     
     
         31 . An elastic pad, comprising
 an elastic base pad comprising a plurality of elastic modules;   the balancing pad of  claim 18 ;   wherein the balancing pad is laid on the elastic based pad, and the plurality of elastic modules are received in the respective receiving spaces, and wherein the limit bosses constrain the movement of the elastic modules in a transverse direction.   
     
     
         32 . The elastic pad of  claim 31  wherein the elastic module is formed in a truncated cone shape and is made to contact at least one limit boss in a form of a truncated cone. 
     
     
         33 . The elastic pad of  claim 31  further comprising a flexible pad and an outer cover, wherein the flexible pad is laid on the base plate, and the outer cover covers the flexible pad and wraps around the balancing pad, the flexible pad and at least a part of the elastic base pad. 
     
     
         34 . Furniture, comprising the elastic pad of  claim 31 .
