FIELD OF THE INVENTION

The invention relates to a table support and, in particular, to a portable table support adjustable to receive a folding table.

BACKGROUND

Collapsible tables with foldable leg braces are generally known in the art. Collapsible folding tables have some distinct advantages over conventional tables because they can be transported to various locations more easily and can be stored in small spaces. Such portability and small size is very important to various professional trades such as massage services where massage practitioners who visit numerous clients at various locations need specialized massage tables to provide their services. The collapsible folding massage table is often transported in the massage practitioner's vehicle from one location to another and carried and set up by the massage practitioner at the client's location. Therefore, such collapsible folding massage tables should be portable, small, light weight and easy to set up and collapse. However, a collapsible massage table, generally, does not provide as much support as a stationary massage table that may include a lift system.
While the stationary massage table provides full support and a range of adjustable features, the stationary massage table, generally, is cumbersome and is not be easily stored. Furthermore, there are massage professionals who are required to purchase both collapsible massage tables and stationary massage tables, in order to accommodate their cliental.

SUMMARY

Accordingly, the invention was devised in light of the problems described above, inter alia, and provides a portable table support that adjust to support a collapsible table, and provides the support of a stationary table.
The portable table support according to the invention includes a lower support structure, a platform disposed on a top surface of the lower support structure, and a pair of adjustable end supports. The a pair of adjustable end supports are attached to the platform such that each of the pair of adjustable end supports have a pair of members that move linearly with respect to each other in opposite directions along a horizontal plane. Further, the pair of adjustable end supports are individually positioned opposite each other at each end of the platform.

DETAILED DESCRIPTION OF THE EMBODIMENT(S)

The invention will now be described in detail with reference to the figures.
With reference to FIG. 1 through 5, a portable table support 1 is shown having a lower support structure 10, adjustable end supports 20, and a middle support 40.
The lower support structure 10, in the embodiment shown, includes a platform 12, support arms 14, and a lifting mechanism 18. The platform 12 is rigid and framed out to support a collapsible massage table (see FIG. 6). The support arms 14 are arranged to rest on a floor a floor or other support structure and extend to attach with the platform 12. In the embodiment shown, the support arms 14 are positioned in a scissor-type manner, wherein both support arms 14 cross each other around a substantial middle section of the support arms 14. However, it is possible that the support arms 14 be positioned such that they may act as a cantilever lift (i.e. powered), in a way which makes it easy and fast to lift a collapsible massage table no matter the size. In the embodiment shown, the support arms 14 attach to lateral supports 16, one which includes wheels 16 a while the other includes stationary stands 16 b, in the embodiment shown.
The adjustable end supports 20 are positioned on the top surface and at both ends of the platform 12, wherein each of the adjustable end supports 20 having members that move linearly with respect to each other in opposite direction along a horizontal plane. The members, which include outer and inner support planks 22, 24, mechanically adjust, and expand horizontally with respect to a longitudinal direction L of the portable support table 1.
The outer support plank 22 includes a sliding channel 22 a that extends in the horizontal direction, and a fastener 22 b. The fastener 22 b extends through this sliding channel 22 a and rigidly attaches to the platform 12. This allows the outer support plank 22 to remain fixed to the top surface of the platform 12, while also permitting the outer support plank 22 to move laterally with respect to the fastener 22 b attached to the side of the platform 12.
The inner support plank 24 includes a sliding channel 24 a that extends in the horizontal direction, as well. A fastener 24 b extends through this sliding channel 24 a and rigidly attaches to the platform 12, on the other side of the platform 12 than where the outer support plank 22 attaches to the platform 12. The sliding channel 22 a, 24 a allow the outer and inner support planks 22, 24 to expand and adjust. Between the outer and inner support planks 22, 24 is a tongue and sliding mechanism 26, which allows the outer and inner support plank 22, 24 to adjust together. When one of the outer or inner support planks 22, 24 is adjusted, the other of the outer and inner support planks 22, 24 is adjusted accordingly so that an attached collapsible massage table has a center of mass in a substantial center of the lower support structure 10. The tongue and sliding mechanism 26 may also include a gear system so that this function is further efficient.
In the embodiment shown, the tongue and sliding mechanism 26 includes a tongue 26 a and a groove 26 b. The tongue 26 a is an integral piece of the inner support plank 24. The tongue 26 a is a protrusion that extends downward from a bottom surface of the inner support plank 24. The tongue 26 a is positioned on a side that will match up with the inner support plank 24. The groove 26 b is a recess in the outer support plank 22, which is capable of receiving the tongue 26 a. When the outer and inner support planks 22, 24 are positioned together, and the fasteners 22 b, 24 b are attached to the platform 12, the outer and inner support planks 22, 24 work together such that the end support 20 can expand while still being attached the platform 12.
The outer and inner support planks 22, 24 include retention pieces 22 c, 24 c that extend from the surface of the outer and inner support planks 22, 24. In the embodiment shown, the retention pieces 22 c, 24 c are positioned such that the outer and inner support planks 22, 24 become L-shaped brackets in order to further support and hold an attaching collapsible massage table.
As shown in the FIG. 2, the sliding channels 22 a, 24 a are aligned with each other, such that each of the sliding channels 22 a, 24 a are positioned between extension pieces of the outer and inner support planks 22, 24. These extension pieces form fit with the opposing outer and inner support planks 22, 24, respectively, and provide more surface area for each outer support plank 22.
In the embodiment shown, the middle support 40 is plank that rigidly attaches to the platform 12 of the lower support structure 10. The middle support 40 includes a table fastener 42 and receiving groove 44. The width of the middle support 40 is substantially the same as the width of the outer support planks 22
The receiving groove 44 is a recess that receives hinges, brackets, or other protrusions of the collapsible massage table (not shown). The table fastener 42 is a temporary fastener capable of securely holding the collapsible massage table (not shown) on top of the outer support plank 22 and the middle support 40. In the embodiment shown, the table fastener 42 is a set of straps having buckles that draw around a connecting collapsible massage table (not shown) and connect to each other. However, it is also possible that the fastener secure the portable table from underneath the table using a rope and cleat system. Other known fastening techniques are possible, such as long as the portable table is supported and secured by the middle 40, which then prevents the attached portable table from moving end to end or lift up in a substantial middle if a cantilevered load is applied at one end of the table.
In the embodiment shown, the lower support structure 10 includes a lifting mechanism 18, which includes a motor and an actuator to adjust the height of the portable table support 1 by causing the support arm 14 connected to the lateral support 16 having wheels to move. The lower support structure 10 and platform 12 may be lowered or tilted the lifting mechanism 18, which may be electronic or hydraulic. It is also possible that this lift mechanism 18, with an adjustable lower support structure 10, may tilt the portable table support 1 at various angles. Furthermore, it is also possible that the lower support structure 10 is adjustable such that one end is lowered with respect to the other end. As a result, the lower support structure 10, with assistance from the lift mechanism 18 when applicable, can adjust the angle of either end of the portable table support 1. However, this would depend on if the attaching portable table is adjustable.
With reference to FIG. 5, fasteners 22 b, 24 b are shown as a nut and bolt configuration. However, other known methods to secure the end supports 20 to the platform 12 are possible. In the embodiment shown, the bolt of the fasteners 22 b, 24 b extends through the sliding channel 22 a, 24 a, and further through a receiving hole in the platform 12. The nut of the fasteners 22 b, 24 b then connects with the bolt, such that the outer and inner support planks 22, 24 are secure to the platform 12. When the fasteners 22 b, 24 b are tightened the outer and inner support planks 22, 24 become more secure, while when loosened the outer and inner support planks 22, 24 become less secure so that the user can adjust the width of the end support 20
With reference to FIG. 6, a collapsible massage table 100 is partially assembled. However, the legs 102 are left under the collapsible massage table 100, and a support surface 104 is only unfolded. The collapsible massage table 100 is then positioned on top of the outer support planks 22 and the middle support 40. The user adjusts the end supports such that the retention pieces 22 c, 24 c grip the outside of the support surface 104. The receiving groove 44 receives the hinges or other protrusions along a folding line 106 of the collapsible massage table 100, and the table fasteners 42 secure the collapsible massage table 100. This allows a user to benefit from a collapsible massage table 100, while also realizing and utilizing the benefits of a stationary support table.
In another embodiment, the end supports 20 and the middle support 40 can rigidly connect to a worktable or bench, such that a collapsible massage table (not shown) could connect easily to the worktable or bench, and be properly supported and secured.
In other embodiments, a single or variety of end supports 20 could be used with or without the middle support 40. The end support 20 may be positioned to and adjust such that the members of the end support, including the outer and inner support planks 22, 24, extend longitudinally, along a length of the lower support structure 10, stationary support, or work bench. Stoppers or retention pieces 22 c, 24 c would abut and secure an end of the collapsible massage table 100, when positioned on the portable table support 1.
Additionally, the shape and configuration of the end support 20 is not limited to that which is shown. Other configurations are possible, such as long as the end support 20 can expand while still being attached to the platform 12. For example, the end support 20 can utilize a telescoping system having two support arms (i.e. telescoping tubing) that expand and retract with respect to each other. It is also the portable table support 1 according to the invention includes a expandable mechanism either attached to or part of the end support 20 that allows a pair of end supports 20 positioned at opposite ends of the portable support 1 to expand or retract with respect to each other along a longitudinal length of the portable table support 1. Accordingly, the end supports 20 not only adjust to accommodate the width of a portable table, but also the length in a further accommodating design.
The foregoing illustrates some of the possibilities for practicing the invention. Many other embodiments are possible within the scope and spirit of the invention. It is, therefore, intended that the foregoing description be regarded as illustrative rather than limiting, and that the scope of the invention is given by the appended claims together with their full range of equivalents.
