Adjustable firmness device and relaxation furniture that comprises said device

Abstract

An adjustable force device for relaxation furniture that comprises a multitude of resilient elements and at least one rigid base element on which the resilient elements rest, in such a way that the resilient elements are intended to compress when receiving pressure and return to their original shape when this pressure is removed, in which at least some of the resilient elements comprise:a head component on the upper part of the resilient element;a means for transmitting tension applied to the head component,the means for transmitting tension to an actuating device of the means for transmitting tension being connected in such a way that the action of the actuating device causes the connected resilient element or elements to compress via the respective means for transmitting tension.

1 . An adjustable force device for relaxation furniture comprising:
 a plurality of elastic bodies and   at least one rigid plate on which the plurality of elastic bodies rest,   wherein the plurality of elastic bodies are configured to be compressed when receiving pressure, and return to their original shape when the pressure is removed,   wherein at least some of the plurality of elastic bodies comprise:
 a head component on an upper part thereof; 
 a link configured to apply tension to the head component, and 
   wherein each link is connected to an actuator such that an action of the actuator causes the at least some of the plurality of elastic bodies to be compressed via the respective links, thereby a neutral position represents the maximum firmness of the device, whereas when the at least some of the plurality of elastic bodies are compressed by the actuator, the firmness of the device is reduced due to a reduction in the number of the elastic bodies in surface area.   
     
     
         2 . The adjustable force device for relaxation furniture according to  claim 1 , wherein the link is a string, a thread or a cable. 
     
     
         3 . The adjustable force device for relaxation furniture according to  claim 1 , wherein each elastic body comprises a spring, springs or a set of springs, or a foam block or set of foam blocks. 
     
     
         4 . The adjustable force device for relaxation furniture according to  claim 1 , wherein the actuator is configured to produce compressions in varying magnitude. 
     
     
         5 . The adjustable force device for relaxation furniture according to  claim 1 , wherein the rigid plate comprises a board or combination of boards, a support structure or combination of support structures. 
     
     
         6 . The adjustable force device for relaxation furniture according to  claim 1 , wherein the actuator is an electrical, mechanical or hydraulic linear actuator, or an electrical, mechanical or hydraulic rotational actuator. 
     
     
         7 . The adjustable force device for relaxation furniture according to  claim 1 , wherein the actuator is operated using a controller communicated by cable, by a radiofrequency device, by an RFID device, via a Bluetooth receiver and computer application; a mobile network or Wi-Fi device; by an electronic or computerized artificial intelligence system, or manually using a system of hand cranks and/or cams actuated by human force. 
     
     
         8 . The adjustable force device for relaxation furniture according to  claim 1 , wherein the actuator is fixed to the rigid plate. 
     
     
         9 . A relaxation furniture comprising the adjustable force device according to  claim 1 . 
     
     
         10 . The relaxation furniture according to  claim 9 , comprising a relaxation surface, wherein the plurality of elastic bodies are positioned in such a way that the plurality of elastic bodies are compressed when receiving the pressure from said surface, and return to their original shape when the pressure is removed. 
     
     
         11 . The relaxation furniture according to  claim 9 , wherein the relaxation furniture is a mattress, chair, armchair or sofa.
