Variable-position ironing board and garment steamer

Abstract

In a variable-position ironing board and a garment steamer, a back side of an ironing board body is rotatably connected to a support structure to allow the ironing board body to be transformed between first and second positions; and a first link and a second link of a locating mechanism are located on the back side of the ironing board body and rotatably connected to the support structure and the ironing board body to form a quadrangle which deforms with the change of the position of the ironing board body, and at least one edge of the quadrangle is provided with a locating portion which, when the ironing board body is transformed between the first position and the second position, leans against an opposite edge of the quadrangle to prevent the quadrangle from deformation so as to locate the ironing board body in the first position or the second position.

1 . A variable-position ironing board, comprising:
 a support structure;   an ironing board body, wherein at a first point (A), a back side of the ironing board body is rotatably connected to the support structure to allow the ironing board to be transformed between a first position and a second position; and   a locating mechanism, comprising a first link and a second link, wherein the first link and the second link are located on the back side of the ironing board body and rotatably connected to the support structure and the ironing board body to form a quadrangle which deforms with a change of the position of the ironing board body, and at least one edge of the quadrangle is provided with locating portion which, when the ironing board body is transformed between the first position and the second position, leans against an opposite edge of the quadrangle to prevent the quadrangle from deformation so as to locate the ironing board body in the first position or the second position.   
     
     
         2 . The variable-position ironing board according to  claim 1 , wherein the quadrangle is prevented from deformation towards a smaller area. 
     
     
         3 . The variable-position ironing board according to  claim 1 , wherein at a second point, the first link is rotatably connected to the back side of the ironing board body; at a third point, the first link is rotatably connected to the second link; at a fourth point, the second link is rotatably connected to the support structure; and the first point, the second point, the third point and the fourth point are four vertexes of the quadrangle. 
     
     
         4 . The variable-position ironing board according to  claim 1 , wherein the locating portion is arranged on the second link, and when the ironing board body is transformed between the first position and the second position, the locating portion leans against the back side of the ironing board body to prevent the quadrangle from deformation so as to locate the ironing board body in the first position or the second position. 
     
     
         5 . The variable-position ironing board according to  claim 4 , wherein the second link has an extended edge extending towards the back side of the ironing board body, and the extended edge is used as the locating portion. 
     
     
         6 . The variable-position ironing board according to  claim 5 , wherein a leaning edge allowing the extended edge to lean again is arranged on the back side of the ironing board body. 
     
     
         7 . The variable-position ironing board according to  claim 4 , wherein the quadrangle is a parallelogram. 
     
     
         8 . The variable-position ironing board according to  claim 1 , wherein rotatable connections are realized by shafts, and an axial direction of the shaft is the same as a with direction of the ironing board. 
     
     
         9 . The variable-position ironing board according to  claim 8 , wherein a width direction of the support structure and the first link is the same as the width direction of the ironing board body, and two said second links are arranged and separately located on two sides of the support structure and the first link. 
     
     
         10 . The variable-position ironing board according to  claim 1 , wherein an inclined section is arranged at an upper end of the support structure and used as an edge of the quadrangle, and the quadrangle is located above the inclined section. 
     
     
         11 . The variable-position ironing board according to  claim 1 , wherein the first position is an upright position, and the second position is a horizontal position. 
     
     
         12 . The variable-position ironing board according to  claim 1 , wherein the quadrangle is provided with a shape-fixing link, and the shape-fixing link is used for fixing a shape of the quadrangle to prevent the quadrangle from deformation so as to fix the ironing board body in an upright position or a horizontal position or at any inclined angle between the upright position and the horizontal position. 
     
     
         13 . The variable-position ironing board according to  claim 1 , wherein the quadrangle is provided with an auxiliary support rod for assisting the quadrangle in deformation. 
     
     
         14 . A garment steamer, comprising the variable-position ironing board according to  claim 1 .
