Arch support reinforcement device

Abstract

An arch support device supports an arch of a user's foot. An arch member forms a substantial arc disposed under the arch of the user's foot, and formed of a resilient material defining a spring capable of deflecting under an applied force. An arch reinforcement member is disposed under the arch member, and is formed of a compressible and elastic material capable of compressing during deflection of the arch member.

1 . An arch support device configured to support an arch of a user's foot, comprising: 
 a) an arch member forming a substantial arc, configured to be disposed under the arch of the user's foot, formed of a resilient material defining a spring capable of deflecting under an applied force; and    b) an arch reinforcement member, disposed under the arch member, formed of a compressible and elastic material capable of compressing during deflection of the arch member.    
   
   
       2 . An arch support device in accordance with  claim 1 , wherein the arch member defines an arch cavity underneath the arch member; wherein the arch reinforcement member has an effective height less than a height of the cavity defining a gap between the arch reinforcement member and a support surface.  
   
   
       3 . An arch support device in accordance with  claim 2 , wherein the arch member is compressible between: 
 a) a first position, in response to a relatively smaller applied force, wherein the arch support member deflects under the applied force without engaging the arch reinforcement member; and    b) a second position, in response to a relatively larger applied force, wherein the arch support member deflects under the applied force engaging the arch reinforcement member to compress the arch reinforcement member.    
   
   
       4 . An arch support device in accordance with  claim 2 , wherein the arch member and the arch reinforcement member have a double resistance response including a first resistance force due to deflection of the arch member and a second resistance force due to deflection of the arch member and compression of the arch reinforcement member.  
   
   
       5 . An arch support device in accordance with  claim 1 , further comprising: 
 matching indentations and protrusions formed between the arch support and arch reinforcement member.    
   
   
       6 . An arch support device in accordance with  claim 1 , further comprising: 
 a plurality of indentations formed in a bottom surface of the arch member; and    a plurality of protrusions formed in an upper surface of the arch reinforcement member.    
   
   
       7 . An arch support device in accordance with  claim 6 , wherein the plurality of indentations and protrusions have a size and walls with a shape longer than the size.  
   
   
       8 . An arch support device in accordance with  claim 6 , wherein the plurality of protrusions is a first plurality of protrusions; and further comprising: 
 a second plurality of protrusions, opposite the first plurality of protrusions, the arch reinforcement member having two orientations with respect to the arch member including a first orientation with the first plurality of protrusions inserted into the plurality of indentations and a second orientation with the second plurality of protrusions inserted into the plurality of indentations.    
   
   
       9 . An arch support device configured to support an arch of a user's foot, comprising: 
 a) an arch member, configured to be disposed under the arch of the user's foot, formed of a resilient material and capable of deflecting under an applied force, and defining a spring capable of storing energy during deflection; and    b) a plurality of indentations formed in a lower surface of the arch member; and    c) the indentations having length; and    d) a plurality of walls, disposed between adjacent indentations; and    e) the walls having a length greater than the length of the indentations.    
   
   
       10 . An arch support device in accordance with  claim 9 , further comprising: 
 an arch reinforcement member, disposed under the arch member, including a first plurality of protrusions extending into the plurality of apertures in the arch member.    
   
   
       11 . An arch support device in accordance with  claim 10 , wherein the arch member defines an arch cavity underneath the arch member; wherein the arch reinforcement member has an effective height less than a height of the cavity defining a gap between the arch reinforcement member and a support surface.  
   
   
       12 . An arch support device in accordance with  claim 11 , wherein the arch member is compressible between: 
 a) a first position, in response to a relatively smaller applied force, wherein the arch support member deflects under the applied force without engaging the arch reinforcement member; and    b) a second position, in response to a relatively larger applied force, wherein the arch support member deflects under the applied force engaging the arch reinforcement member to compress the arch reinforcement member.    
   
   
       13 . An arch support device in accordance with  claim 10 , wherein the arch member and the arch reinforcement member have a double resistance response including a first resistance force due to deflection of the arch member and a second resistance force due to deflection of the arch member and compression of the arch reinforcement member.  
   
   
       14 . An arch support device in accordance with  claim 10 , further comprising: 
 a second plurality of protrusions, opposite the first plurality of protrusions, the arch reinforcement member having two orientations with respect to the arch member including a first orientation with the first plurality of protrusions inserted into the plurality of indentations and a second orientation with the second plurality of protrusions inserted into the plurality of indentations.    
   
   
       15 . An arch support reinforcement device, comprising: 
 a) a partially compressible and elastic material configured to be secured to a bottom of an arch support and in a gap formed between the arch support and a support surface;    b) a plurality of protrusions extending upwardly configured to be received within a plurality of indentations in the arch support; and    c) a second plurality of protrusions extending downwardly.    
   
   
       16 . An arch support reinforcement device in accordance with  claim 15 , wherein the plurality of protrusions have a size and walls with a shape longer than the size.
