The invention relates to tables that are collapsible, lightweight and portable.
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's competitor's goals are: less weight, strength, weight capacity and stability.
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.
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.
FIG. 1 is a perspective bottom view of the electric collapsible table according to the invention.
FIG. 2 shows a bottom view of the electric collapsible table with the column system legs structures fold against the frame.
FIG. 3 is a perspective view of the electric collapsible table totally closed and ready to be transported.
FIG. 4 shows the stabilizer structure.
FIG. 5 shows the leg support structure.
FIG. 6 shows the electric acme screw system.
FIG. 7 shows the triangular traveler structure.
FIG. 8 shows the structures of the FIGS. 5-6-7 ready assembled.
FIG. 9 shows the column system leg structure ready assembled.
FIG. 10 shows in detail the electric acme screw system 20i pulled-up along with the stabilizer structure 16 and the triangular traveler structure 19, on the track of the leg support structure 15.
FIG. 11 shows the triangular flexible cable frame 23, which hooks its center hard angle 23b in to the hook 19i of FIG. 10.
FIG. 12 shows the in detail the pivoting hinges 22 on frames 11.
FIG. 13 shows the trapeze-shape central truss member.
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.
When table 10 is set up, it has four corner regions, two on each opposite end of the center region.
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 16a 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 17a FIG. 13.
Trapeze-shape truss member 17 has two cables attachment points 17b 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.
The triangular flexible cables 23, secured on frame 11 by holders 23a, have a center hard angle 23b FIG. 11 which hooks manually on hook 19i 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.
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 15a FIG. 5 allowing the triangular traveler structure 19 FIG. 7 to slide up and down on the track along the U-nylon guide 19c FIG. 7 fastened by U-metal support 19b. The upper end of the triangular traveler structure 19a FIG. 7, the upper end of the acme screw 20a FIG. 6 and the central holder 16b FIG. 4 of the stabilizer structure 16 FIG. 4 are connected by a bolt. The bottom of the stabilizer structure 16c FIG. 4, and the bottom of the triangular traveler structure 19d FIG. 7 are connected with bolts. The upper ends of the stabilizer structure 16a 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.
