Method and Apparatus for Adjusting Heights of Objects

Abstract

A leg adjusting assembly has a housing, a rod that moves through the housing, a foot mechanism, and a biasing member. The rod moves through a hole in the housing and a hole in the foot mechanism. The biasing member moves the foot mechanism against the rod and prevents the rod from moving within the housing. A foot-activated force applied to the foot mechanism enables the rod to move and alter a height of the leg of a table or chair.

1 . A leg adjusting assembly, comprising:
 a housing that has a hole and that has a shape to connect to a leg of a table;   a foot mechanism that extends outwardly from the housing and that has a leg with a hole that aligns with the hole in the housing;   a rod that moves through the hole in the housing and through the hole in the foot mechanism; and   a biasing member positioned around the rod in order to bias an interior wall of the hole in the foot mechanism against an exterior surface of the rod to prevent the rod from moving during absence of a force applied to the foot mechanism.   
     
     
         2 . The leg adjusting assembly of  claim 1 , wherein the foot mechanism is T-shaped. 
     
     
         3 . The leg adjusting assembly of  claim 1 , wherein the force applied to the foot mechanism with a foot of a user causes the interior wall of the hole of the foot mechanism to disengage from the exterior surface of the rod and enables the rod to vertically move within a cavity formed in the housing to adjust a height of the table. 
     
     
         4 . The leg adjusting assembly of  claim 1 , wherein the housing has a rectangular shaped main body with two winged rectangular portions that extend outwardly from opposite sides of the main body. 
     
     
         5 . The leg adjusting assembly of  claim 1 , wherein housing has an elongated and rectangular-shaped flat support with a rounded end that extends outwardly from the housing. 
     
     
         6 . The leg adjusting assembly of  claim 1 , wherein the housing has a cavity that houses a leg of the foot mechanism and the rod. 
     
     
         7 . The leg adjusting assembly of  claim 1  further comprising: a cap that connects to one end of the rod in order to prevent the rod from falling through the hole in the foot mechanism and through the hole in the housing. 
     
     
         8 . The leg adjusting assembly of  claim 1 , wherein the housing has (1) a first portion with a rectangular configuration forming a cavity for receiving the rod and a leg of the foot mechanism and (2) a second portion having an elongated rectangular shape with a hole for attaching to the leg of the table. 
     
     
         9 . The leg adjusting assembly of  claim 1 , wherein the foot mechanism has a leg that includes the hole in the foot mechanism, has a lever portion that is perpendicular to the leg, and has a canted portion that connects the leg of the foot mechanism to the lever portion. 
     
     
         10 . A leg adjusting assembly that adjusts a height of a table leg, comprising:
 a housing that includes an internal cavity and two oppositely disposed holes that align with each other;   a foot mechanism that includes a hole that aligns with the two holes in the housing, a leg portion that extends into the internal cavity, and a lever portion that connects to the leg portion and extends outwardly from the housing;   a rod that is moves through the two holes in the housing and through the hole in the foot mechanism and that includes one end with a glide that supports the leg adjusting assembly on a ground and that includes another end with cap that holds the rod within the internal cavity; and   a biasing member connected to the rod in order to bias an interior wall of the hole of the foot mechanism against an exterior surface of the rod to prevent the rod from moving during absence of a force applied to the foot mechanism.   
     
     
         11 . The leg adjusting assembly of  claim 10 , wherein the rod moves inside the internal cavity to adjust the height of the table leg. 
     
     
         12 . The leg adjusting assembly of  claim 10 , wherein the foot mechanism has a T-shape with a leg portion that extends within the internal cavity and a lever portion that extends outwardly from the housing. 
     
     
         13 . The leg adjusting assembly of  claim 10 , wherein the rod moves within the internal cavity in a vertical direction with respect to a surface on which the table leg is positioned in order to adjust the height of the table leg. 
     
     
         14 . The leg adjusting assembly of  claim 10 , wherein the housing has a rectangular shaped main body with two winged rectangular portions that extend outwardly from opposite sides of the main body. 
     
     
         15 . The leg adjusting assembly of  claim 10 , wherein the rod moves within the internal cavity while the force is applied to the lever, and the foot mechanism re-engages against the rod when the force is removed from the foot mechanism. 
     
     
         16 . A leg adjusting assembly, comprising:
 a housing including a cavity and body that abuts a leg of a table;   a rod movable through a hole formed in the housing and into the cavity;   a T-shaped foot mechanism including a leg being positioned in the housing and having a hole with an interior surface, and including a lever connected to the leg such that the lever extends outwardly from the housing and is perpendicular to the leg; and   a biasing member that moves the foot mechanism against the rod until the interior surface wedges against an exterior surface of the rod and prevents the rod from moving within the housing, wherein a foot activated force applied to the lever disengages the interior surface of the hole from the exterior surface of the rod to alter a height of the table.   
     
     
         17 . The leg adjusting assembly of  claim 16 , wherein the biasing member is a spring that fits around the rod. 
     
     
         18 . The leg adjusting assembly of  claim 16 , wherein the rod has one end with a removable cap and another end with a glide that supports the leg of the table on a ground. 
     
     
         19 . The leg adjusting assembly of  claim 16 , wherein the lever has a flat rectangular shape with two rounded ends oppositely disposed from each other. 
     
     
         20 . The leg adjusting assembly of  claim 16 , wherein the housing has a rectangular shaped main body with two winged rectangular portions that extend outwardly from opposite sides of the main body.
