Sewing machine table

Abstract

The present invention relates to a sewing machine table. The sewing machine table with a rotatable operating foot pedal connected to a driving motor for a sewing machine, comprises: an upper frame provided with a top plate on which the sewing machine is installed, and a lower frame including: height adjustable supports provided at bottom ends of the upper frame for supporting the top plate and adjusting a height of the top plate; lower supports coupled to bottom ends of the height adjustable supports, and a first lower connecting plate coupled between the lower supports, the first lower connecting plate on which the operating foot pedal is installed. With this configuration, the sewing machine table is provided with an upper support coupled to a top plate and a cylinder inserted in the upper support and capable of adjusting a height, thereby enabling a height of the top plate to be adjusted according to a body size of an operator and increasing work efficiency.

What is claimed is: 
     
         1 . A sewing machine table with a rotatable operating foot pedal connected to a driving motor for a sewing machine, the sewing machine table comprising:
 an upper frame provided with a top plate on which the sewing machine is installed, and a lower frame including:   height adjustable supports provided at bottom ends of the upper frame for supporting the top plate and adjusting a height of the top plate;   lower supports coupled to bottom ends of the height adjustable supports, and a first lower connecting plate coupled between the lower supports, the first lower connecting plate on which the operating foot pedal is installed.   
     
     
         2 . The sewing machine table of  claim 1 , wherein the first lower connecting plate is coupled to the lower supports in a movable and rotatable manner along a longitudinal direction of the lower supports. 
     
     
         3 . The sewing machine table of  claim 1 , wherein the height adjustable supports include:
 operational cylinders coupled to the top plate, and   piston rods operated by the operational cylinders.   
     
     
         4 . The sewing machine table of  claim 3 , wherein an upper connecting plate is coupled between the operational cylinders so that both are supported by each other,
 wherein a second lower connecting plate extended upward to be disposed in parallel with the upper connecting plate is coupled between upper portions of the lower supports,   wherein a first fixing protrusion drawn out by elasticity and formed of magnetic material is formed on a side surface of the upper connecting plate, which faces the second lower connecting plate,   wherein locking holes that are formed at an equal interval in a vertical direction and that the first fixing protrusion is inserted into and magnetically fixed to are formed on a side surface of the second lower connecting plate, which faces the upper connecting plate.   
     
     
         5 . The sewing machine table of  claim 1 , wherein second fixing protrusions to which rollers are coupled are formed on both sides of the first lower connecting plate, respectively,
 wherein slide grooves to which the rollers are movably coupled are formed on side surfaces of the lower supports, which face each other,   wherein a moving groove connected to the slide groove is formed on each outer side surface of the lower supports so that the second fixing protrusions protrude to the outside,   wherein a fixing member fixing the first lower connecting plate is engaged with the second fixing protrusion protruding to the outside through the moving groove.
