DESCRIPTION

FIELD OF INVENTION

The invention relates to tables that are collapsible, lightweight and portable.

BACKGROUND OF THE INVENTION

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.

SUMMARY OF THE INVENTION

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. 10 shows in detail the electric acme screw system 20 i 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 23 b in to the hook 19 i 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.

DESCRPTION OF THE INVENTION

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 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.
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.
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.
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.

Claims

1. Electric portable collapsible table

2. The frame of the table of claim 1, is supported by two electrically motorized acme leg system one on each opposing end. The two legs system is connected by two cables, from the upper end of one central frame of the leg system to the lower end of the opposite central frame system making an x-shape wire structure plus two triangular wire structures on each end in order to stabilized the legs systems in a vertical direction toward the ground when the table is set up. This system allows the table of claim 1 to be adjusted up and down simultaneously.

3. The table of claim 1, has on each opposite end an electric motor with an acme screw, vertically mounted on the lower triangular frame leg that support the table, linked to the folding triangular stabilizer structure at the middle of the horizontal bar, and guided by the vertical track and activated by the traveler triangle structure making it possible the system leg to extend and retract electrically.

4. The table of claim 3, has a flexible cable fixed from one corner end of the table to the opposite corner end so when the table is set up it secures on the hook at the center of the traveler triangular structure which is attached to the electrically motorized acme screw.

5. The table of claim 2, wherein is linked by two flexible cables, one connected from the upper central frame of the leg system to the lower end of the opposite central frame of the leg system and the other one vice versa forming and x-shape complementing the table of claim 3 to maintain the strength of the table when it is set up

6. The table of claim 1, wherein the central trapeze-shaped truss member is positioned in one of the table pieces at the hinges end via folding links that folds-in and folds-out all the way from the table piece, comprising the two table pieces to be co-linear, reaching the maximum strength when the table is totally set up.

7. The table of claim 6 has a central trapeze-shaped truss member wherein the cable portion for each corner region of the table is connected thru it, to keep the two frame-table co-linear.

8. The table of claim 1 wherein triangular traveler structure.

9. The table of claim 1 wherein stabilizer structure.

10. The table of claim 1 wherein leg support structure.

11. The table of claim 1 wherein flexible cable frame.

12. The table of claim 1 wherein pivoting hinges.
