Table and Chair Structure for Assembling Bed

Abstract

A table and chair structure for assembling bed comprises a chair, and a table comprising two sets of lateral leg frames correspondingly coupled with a front and a rear horizontal supporting beams therebetween for placing a lower carrier plate. At least two movable leg frames which can slide outwardly are disposed on bottom sides of the two front and rear horizontal supporting beams. An upper side of the connecting frame is pivotally connected with a side of a movable table plate. Thereby, the movable table plate can be turned pivotally and upwardly and placed on the two lateral leg frames for forming a table surface; and can be turned pivotally and downwardly and placed on the movable leg frames to be leveled with a chair surface of the chair for connecting and forming a bed surface with the chair.

What is claimed is: 
     
         1 . A table and chair structure for assembling bed comprising:
 a chair having a chair surface for sitting; and   a table comprising two sets of lateral leg frames correspondingly coupled with a front and a rear horizontal supporting beams therebetween for placing a lower carrier plate, at least two movable leg frames slide outwardly being disposed on bottom sides of the two front and rear horizontal supporting beams, a side of the lower carrier plate from where the movable leg frames slide outwardly being pivotally connected with a connecting frame, an upper side of the connecting frame being pivotally connected with a side of a movable table plate to cause the movable table plate to turn pivotally and upwardly, and place on the two lateral leg frames to form a table surface, and to turn pivotally and downwardly, and place on the movable leg frames and the chair surface of the chair for connecting and forming a bed surface with the chair.   
     
     
         2 . The table and chair structure for assembling bed as claimed in  claim 1 , wherein a chair back is and armrests are respectively disposed on a rear side and two lateral sides of the chair surface of the chair. A placing groove with a height equivalent to a thickness of the movable table plate is disposed at a front side of the chair surface for placing the movable table plate to be leveled with the chair surface. 
     
     
         3 . The table and chair structure for assembling bed as claimed in  claim 1 , wherein at least two slidable guiding columns are protrudingly disposed on bottom sides of the two front and rear horizontal supporting beams of the two lateral leg frames for respectively inserting into a sliding groove with a shape matching that of the slidable guiding column in an upper horizontal beam of one of the movable leg frames for forming a combination for sliding outwardly. A movable supporting rod is pivotally connected from an outer end of the sliding groove of the movable leg frame, and a hooking portion is formed by bending an outer end of the movable supporting rod for correspondingly hooking and connecting fixedly with the placing groove. 
     
     
         4 . The table and chair structure for assembling bed as claimed in  claim 1 , wherein the movable leg frame comprises an upper retractable horizontal frame having a retractable inner frame, a movable supporting rod which can be slide outwardly is sleeved and assembled at an outer end of the retractable inner frame, and a coupling plate is fixedly coupled on the bottom side of the horizontal supporting beam by two sides of the upper retractable horizontal frame. A roller is disposed on a lower end of the movable leg frame. A hooking portion is formed by bending an outer end of the movable supporting rod for hooking and connecting fixedly with the placing groove. 
     
     
         5 . The table and chair structure for assembling bed as claimed in  claim 3 , wherein the sliding groove in the upper horizontal beam of the movable leg frame and the slidable guiding column of the horizontal supporting beam together form an upside-down T shaped sectional concave and convex structure, and guiding wheels are further pivotally disposed on two sides of the upside-down T shaped sectional structure of the slidable guiding column. 
     
     
         6 . The table and chair structure for assembling bed as claimed in  claim 1 , wherein the chair is made of steel tubes and the table is made of steel tubes. 
     
     
         7 . The table and chair structure for assembling bed as claimed in  claim 1 , wherein the chair is entirely made of wood, and the table and the movable table plate are made of wood. A surface of the movable table plate is coupled with an outer coating, wherein the outer coating is selected from wooden coating, genuine leather, PU coating or PVC coating. 
     
     
         8 . The table and chair structure for assembling bed as claimed in  claim 1 , wherein the chair is made of both steel tubes and wood. The two lateral leg frames as well as the correspondingly coupled front and rear horizontal supporting beams of the table are made of steel tubes. The movable table plate and the lower carrier plate are made of wood. The surface of the movable table plate is coupled with an outer coating, wherein the outer coating is selected from wooden coating, genuine leather, PU coating or PVC coating. 
     
     
         9 . The table and chair structure for assembling bed as claimed in  claim 1 , wherein a foldable pad is further provided for placing on the chair surface as a folded and reduced structure and placing on the bed surface as an unfolded structure. The foldable pad is made of fabric cover with sponge lining or leather cover with sponge lining. 
     
     
         10 . The table and chair structure for assembling bed as claimed in  claim 1 , wherein a limiting hole is disposed on an upper side of the lateral leg frame for sleeving a limiting sleeve with two adjusting holes disposed on an outer wall of the limiting sleeve, and a limiting column with an elastic steel ball disposed on an outer wall of the limiting column is sleeved inside the limiting sleeve for forming a height adjustable assembly. When the elastic steel ball of the limiting column is disposed in an upper adjusting hole, an upper end of the limiting column is protruded outside a surface of the upper side of the lateral leg frame. In conjunction with two limiting holes concavely disposed on the movable table plate in corresponding to the two limiting columns, when the movable table plate is placed across the two lateral leg frames, the concavely disposed limiting holes and the limiting columns are correspondingly assembled for providing a combination with an extra stability.
