Abstract:
The electric collapsible massage table consists of two folding table pieces hingably connected to each other, a two leg systems designed with the electrical and mechanical technology that allows the table to move up and down simultaneously and a structural collapsible cable system to support and strength once the table is set up and loaded.

       DESCRIPTION  
     FIELD OF INVENTION  
       [0003]     The invention relates to tables that are collapsible, lightweight and portable.  
       BACKGROUND OF THE INVENTION  
       [0004]     Due to the growing collapsible massage table demand there is an interesting market. Collapsible massage tables can be compactly stored, and can be easily transported for use at different locations, the designer&#39;s competitor&#39;s goals are: less weight, strength, weight capacity and stability.  
         [0005]     Most of the collapsible tables existing in the market have variations on their design, achieving the mentioned common goals without any automatic system to change its height. The electrical motorized adjustment of its height will make the practitioner job a lot easier and the best of all, it will prevent future health problems because his/her posture will be proper at all times.  
       SUMMARY OF THE INVENTION  
       [0006]     The invention introduces a electrical collapsible massage table with an electric motorized mechanism which is not found in any other portable collapsible massage table in the market. The electrical motorized mechanism allows the table to move up and down even when it is not loaded. It is done by the touch of a command.

     DESCRPTION OF THE INVENTION  
       [0020]      FIG. 1  shows a perspective of invention table  10  from bottom view which includes table frames  11 , connected in a center region by pivoting hinges  22   FIG. 12 , so the table frames  11  are substantially co-planar when table  10  is set up. When table  10  is collapsed, table frames  11  fold together and contain all of the supports cables parts and mechanism shown in  FIG. 1 .  
         [0021]     When table  10  is set up, it has four corner regions, two on each opposite end of the center region.  
         [0022]     Unless otherwise stated, description of the support mechanism below one corner region is the same for the other corner region. The same numbers and letters are used to designate analogous structure under different regions of the table. The column system leg structures  15 - 16 - 19 - 20   FIG. 9 , folds against table frames  11  via pivotal links  16   a    FIG. 4 , as well as the trapeze-shape central truss member  17  pivotally attached under the center region of table frames  11  via pivotal links  17   a    FIG. 13 .  
         [0023]     Trapeze-shape truss member  17  has two cables attachment points  17   b    FIG. 13  through which the flexible end-to-end cable  21  passes. When table  10  is set up, the cables  21  provides a very important structural effect supporting the center region of the table  10  without interference to the massage practitioner.  
         [0024]     The triangular flexible cables  23 , secured on frame  11  by holders  23   a , have a center hard angle  23   b    FIG. 11  which hooks manually on hook  19   i    FIG. 10  of the column system leg structure  15 - 16 - 19 - 20   FIG. 9 . When the table is set up the triangular flexible cables  23  tighten the cables  21  forming a x-shaped tensors, making the table  10  rigid and strong.  
         [0025]     When table  10  is set up, the column system leg structure  FIG. 9  is ready to move vertically up and down, activated by the electric acme screw system  20   FIG. 6  supported on the leg structure  15   FIG. 5  that has a vertical track  15   a    FIG. 5  allowing the triangular traveler structure  19   FIG. 7  to slide up and down on the track along the U-nylon guide  19   c    FIG. 7  fastened by U-metal support  19   b . The upper end of the triangular traveler structure  19   a    FIG. 7 , the upper end of the acme screw  20   a    FIG. 6  and the central holder  16   b    FIG. 4  of the stabilizer structure  16   FIG. 4  are connected by a bolt. The bottom of the stabilizer structure  16   c    FIG. 4 , and the bottom of the triangular traveler structure  19   d    FIG. 7  are connected with bolts. The upper ends of the stabilizer structure  16   a    FIG. 4  are linked to the frames  11  of the table  10   FIG. 1  via pivots making it possible for frames  11  of table  10   FIG. 1  to move up and down while maintaining great strength, stability and firmness even unloaded.
