Height adjustable furniture leg

Abstract

The present invention relates to a height-adjustable furniture leg configured to provide seamless and stable height adjustment while maintaining an aesthetically cohesive appearance. The furniture leg includes a base mountable to a furniture frame, a leg member extending downward, and an adjustment mechanism disposed at the upper portion of the leg member. The adjustment mechanism enables selective height variation through rotational or telescoping engagement while concealing parting seams from normal viewing angles. A locking mechanism prevents unintentional height changes, ensuring stability. The leg member may include grip-enhancing textures for ease of manual adjustment. A concealment structure, such as an overlapping flange, automatically repositions to obscure the adjustment interface during operation. The lower end of the leg member may incorporate a foot portion designed to distribute weight evenly across a surface. The invention enhances furniture stability, durability, and user convenience without requiring additional tools for height adjustment.

         5 . The height-adjustable furniture leg of  claim 1 , wherein the leg member comprises an outer sleeve and an inner telescoping section, the inner telescoping section being configured to move relative to the outer sleeve to vary the height. 
     
     
         6 . The height-adjustable furniture leg of  claim 5 , wherein the outer sleeve includes an internal guide structure configured to maintain axial alignment of the inner telescoping section. 
     
     
         7 . The height-adjustable furniture leg of  claim 1 , wherein the adjustment mechanism is manually operable without requiring tools. 
     
     
         8 . The height-adjustable furniture leg of  claim 7 , wherein the adjustment mechanism includes a grip-enhancing surface on an exterior portion of the leg member to facilitate manual rotation. 
     
     
         9 . The height-adjustable furniture leg of  claim 1 , wherein the leg member comprises a cylindrical shape. 
     
     
         10 . The height-adjustable furniture leg of  claim 9 , wherein the cylindrical shape includes a knurled or textured exterior surface to enhance grip for manual adjustment. 
     
     
         11 . The height-adjustable furniture leg of  claim 1 , wherein the base is secured to the furniture frame using a plurality of fasteners arranged circumferentially around the base. 
     
     
         12 . The height-adjustable furniture leg of  claim 11 , wherein the base includes pre-formed mounting holes to receive the plurality of fasteners. 
     
     
         13 . The height-adjustable furniture leg of  claim 1 , wherein the concealment structure is configured to automatically reposition as the leg member is adjusted, maintaining coverage of the parting seam. 
     
     
         14 . The height-adjustable furniture leg of  claim 1 , wherein the leg member is composed of a metal material selected from the group consisting of aluminum, steel, and an alloy thereof. 
     
     
         15 . The height-adjustable furniture leg of  claim 1 , wherein the concealment structure is composed of a flexible material to allow for seamless coverage of the parting seam. 
     
     
         16 . The height-adjustable furniture leg of  claim 1 , wherein the adjustment mechanism includes a detent system that provides discrete height settings. 
     
     
         17 . The height-adjustable furniture leg of  claim 1 , wherein the adjustment mechanism is configured to provide a continuous range of height adjustment between a minimum and maximum position. 
     
     
         18 . The height-adjustable furniture leg of  claim 1 , wherein the leg member further comprises a load-bearing foot at the lower end, the foot being configured to distribute weight evenly across a support surface. 
     
     
         19 . A height-adjustable furniture leg, comprising:
 a base configured to be mounted to an underside of a furniture frame, the base including a plurality of pre-formed mounting holes for receiving fasteners;   a leg member having an upper end and a lower end, the upper end being rotatably coupled to the base;   an adjustment mechanism comprising a threaded connection between the base and the upper end of the leg member, the threaded connection configured to selectively vary the height of the leg member relative to the base through manual rotation;   a locking mechanism operably engaged with the threaded connection to prevent unintentional height changes;   a concealment structure comprising an overlapping flange extending from the base, the concealment structure configured to obscure a parting seam created by adjustment of the leg member from a normal viewing perspective when the furniture is in use; and   a grip-enhancing surface disposed on an exterior portion of the leg member to facilitate manual rotation for height adjustment.   
     
     
         20 . A height-adjustable furniture leg, comprising:
 a base configured to be mounted to an underside of a furniture frame, the base including a plurality of pre-formed mounting holes for receiving fasteners;   a leg member having an upper end and a lower end, the upper end being rotatably coupled to the base, wherein the leg member comprises a cylindrical outer sleeve and an inner telescoping section configured to move relative to the outer sleeve to vary the height;   an adjustment mechanism comprising a threaded connection between the base and the upper end of the leg member, the threaded connection configured to selectively vary the height of the leg member relative to the base through manual rotation;   a detent system integrated with the adjustment mechanism, the detent system providing discrete height settings to ensure secure positioning at different height levels;   a locking mechanism operably engaged with the threaded connection to prevent unintentional height changes;   a concealment structure comprising an overlapping flange extending from the base, the concealment structure being composed of a flexible material configured to automatically reposition as the leg member is adjusted to obscure a parting seam from a normal viewing perspective when the furniture is in use;   a grip-enhancing surface disposed on an exterior portion of the leg member to facilitate manual rotation for height adjustment; and   a load-bearing foot at the lower end of the leg member, the load-bearing foot configured to distribute weight evenly across a support surface.
