DESCRIPTION

FIG. 1 is a simplified bottom perspective view of a massage table 10 having features of the present invention. In this embodiment, the massage table 10 includes a table top assembly 12, a leg assembly 14, and a brace assembly 16. It should be noted that one or more leg cross-braces and/or cables can be used to additionally support the leg assembly 14. The cross-braces and cables are not shown in FIG. 1 so that other features of the table top assembly 12 can be better understood. One embodiment of the leg assembly 14, the brace assembly 16, the leg cross-braces and cable structure is disclosed U.S. Pat. No. 5,009,170, issued to Spehar, the contents of which are incorporated herein by reference.
In certain embodiments, the massage table 10 is a portable, folding massage table that is moveable between a working configuration (illustrated in FIG. 1) and a transport configuration. In the working configuration, the massage table 10 can be set up on a surface 18 (only partly illustrated in FIG. 1) such as a floor or ground, and the massage table 10 is ready for usage.
The table top assembly 12 provides a resting surface for a person to rest on during a massage. In one embodiment, the table top assembly 12 includes a first table top 22A, an adjacent second table top 22B, and a hinge assembly 24 that connects the table tops 22A, 22B together. Additionally, the table top assembly 12 can include a headrest (not shown) that extends away from the front of the first table top 22A.
In the embodiment illustrated in FIG. 1, each table top 22A, 22B is generally rectangular shaped. Alternatively, for example, one or both table tops 22A, 22B can be another shape, such an oval shape or rectangular shape with one or more rounded corners.
Each table top 22A, 22B includes a frame 30. In one embodiment, each frame 30 includes a frame base 34 and a peripheral border flange 36 that is secured to and cantilevers downward from the perimeter of the frame base 34. In one embodiment, frame base 34 includes a generally rigid base support 34A and a plurality of spaced apart base apertures 34B that extend through the rigid base support 34A. The plurality of base apertures 34B reduce the weight of the frame base 34 and the overall weight of the massage table 10. As a result thereof, the massage table 10 is easier to transport.
In the embodiment illustrated in FIG. 1, the frame base 34 is made of perforated plywood. In this embodiment, the base support 34A is generally rectangular sheet shaped piece of plywood and material has been removed to form the base apertures 34B. In alternative, non-exclusive embodiments, the plywood of the base support 34A has a thickness of approximately 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 1 inches. However, other thicknesses can be utilized.
Alternatively, the frame base 34 can be made of another generally rigid material such as plastic, Kevlar, nylon or another rigid material.
The number, spacing, size and shape of the base apertures 34B can be varied to achieve the desired strength and weight characteristics of the massage table 10. In one embodiment, the base apertures 34B includes a plurality of spaced apart first apertures 34C having a circular shape and a plurality of spaced apart second apertures 34D having a triangular shape. Alternatively, one or more of the base apertures 34 can have a different configuration. For example, one or more of the base apertures 34 can have rectangular, octagon, or pentagon shape.
In alternative, non-exclusive embodiments, each base aperture 34B has a base area of at least approximately 1, 2, 4, 6, 10 or 20 square inches. However, other sizes are possible.
The pattern of the base apertures 34B can be varied to achieve the desired weight and strength requirements of the massage table 10. In one embodiment, the first apertures 34C are aligned in a generally linear first row 34E and the second apertures 34D are aligned in a generally linear second row 34F. In FIG. 1, each table top 22A, 22B includes a pattern that include two second rows 34F of the second apertures 34C (with the triangles in each second row 34F inverted relative to the other second row 34F) followed by a first row 34E of first apertures 34D.
In alternative, non-exclusive embodiments, the collective aperture areas of the base apertures 34B is approximately 5, 10, 15, 20, 25, 30, 33, 35, 40, or 50 percent of a support area of the base support 34A.
In some embodiments, the strips of the base support 34A (e.g. plywood) remaining in the frame base 34 are aligned to transfer the load to the border flange 36. For example, the base support 34A can have a minimum of 2 inch wide strips, and/or the strips that remain in the base support 34A are aligned to connect the four sides of the border flange 36 at angles of approximately 30, 60 and 90 degrees.
In certain embodiments, the base apertures 34B are positioned away form the edge of frame base 34 and away from the attachment points of the legs 38 and the brace assembly 16. In alternative, non-exclusive embodiments, each of the base apertures 34B is positioned an aperture distance 39 of at least approximately 1, 1.5, 2, 2.5, 3, or 4 inches from the border flange 36. However, other distances are possible.
The border flange 36 is generally rectangular frame shaped and includes a front side 36A (as viewed in FIG. 1), a rear side 36B, a left side 36C, and a right side 36D. Alternatively, the sides 36A-36D can be referred to as first through fourth sides. In one embodiment, each of the sides 36A-36D is rectangular beam shaped. In alternative non-exclusive embodiments, each of the sides 36A-36D has a width of approximately 0.2, 0.3, 0.4, 0.5, 0.6, or 1 inch and a height of approximately 1, 1.2, 1.4, 1.6, 1.8, or 2 inches. Alternatively, the sides 36A-36D could have another configuration.
The frame base 34 and/or the border flange 36 can be made of a rigid material such wood, aluminum, plastic or other suitable materials.
The hinge assembly 24 connects the table tops 22A, 22B together and allows the table tops 22A, 22B to pivot relative to each other between (i) the working configuration in which the table tops 22A, 22B are substantially in the same plane, and (ii) the transport configuration in which the table tops 22A, 22B are in substantially parallel planes and the border flange 36 of the first table top 22A is adjacent to the border flange 36 of the second table top 22B. In one embodiment, the hinge assembly 24 is a piano hinge that is attached to the border flange 36 of the first table top 22A at the right side, and the border flange 36 of the second table top 22B at the left side. Alternatively, the hinge assembly 24 can have another design.
The leg assembly 14 supports the table top assembly 12 above the surface 18. In one embodiment, the leg assembly 14 includes four spaced apart legs 38 that are pivotable and moveable connected to the border flange 36 and/or the rest of the table top assembly 12. In FIG. 1, legs 38 are positioned near the four corners of the table top assembly 12. Alternatively, the leg assembly 14 could be designed with more than four or less than four legs 38 and/or the legs 38 can be positioned in another location than the four corners.
The brace assembly 16 extends betweens the table top assembly 12 and leg assembly 14 to provide additional support to the leg assembly 14 when the massage table 10 is in the working configuration 18. Further, the brace assembly 16 allows the legs 38 to be easily moved between the folded position (not shown), and the unfolded position illustrated in FIG. 1.
FIG. 2 is a cut-away view of the second table top 22B taken on line 2-2 in FIG. 1. It should be noted that the first table top 22A can have a similar configuration to that illustrated in FIG. 2. In this embodiment, in addition to the frame base 34 and the border flange 36, the table top 22A includes (i) a support pad 242 that is adjacent to the frame base 34, (ii) a reinforcement sheet 244 that is wrapped around the support pad 242 and that is secured to the border flange 36, (iii) a cushion pad 246 that is positioned over the reinforcement sheet 244, and (iv) a covering 248 that is wrapped around the cushion pad 246 and that is secured to the border flange 36. The design of each of these components can be varied to achieve the desired strength and comfort characteristics of the massage table 10.
The support pad 242 provides some strength to the table top 22B and distributes loads that are applied to the top of the table top 22B to the frame base 34. Stated in another fashion, the support pad 242 distributes point loading to a relatively wide area on the frame base 34 (over approximately 6 inch diameter in certain embodiments).
In one embodiment, the support pad 242 is bonded to the frame base 34 with an adhesive 250, e.g. contact cement. The bonded interface increases the tension load in the frame base 34 and stiffens the structure of the table top 22B. An optional feature of the support pad 242 is that a relatively large chamfer 250 or radius can be used on the top edge of the support pad 242. This feature can increase the stiffness and strength of the reinforcement sheet 344 which is wrapped around this edge. Further, the support pad 242 can distribute point loads that are applied to the top of the massage table.
Non-exclusive examples of suitable materials for the support pad 242 include ethylene foam, urethane foam and Styrofoam. The support pad 242 can be blue or some other color that and is visible through the base apertures 34B in the frame base 34. In non-exclusive embodiments, the support pad 242 has a thickness of approximately 0.5, 1, 1.5, or 2 inch.
In one embodiment, the support pad 242 is lighter in weight and stiffer than the cushion pad 246.
In one embodiment, the reinforcement sheet 244 is an Olefin fiber sheet. For example, the reinforcement sheet can made of HDPE fiber. A suitable material is sold under the trademark Tyvek, by DuPont. The reinforcement sheet 244 can be tear proof and very strong. As provided herein, the table top 22B can be assembled so that the reinforcement sheet 244 supports a portion of the load under tension. In certain designs, the reinforcement sheet 244 is attached, e.g. by an adhesive 254, e.g. contact cement, to the support pad 242. The bonding can create two important benefits. First, the bonding reduces and/or eliminates crunching noise in the reinforcement sheet 244. Second the bonding increases the tension load on the reinforcement sheet 244. In alternative, non-exclusive embodiments, the reinforcement sheet 244 has a thickness of approximately 5, 10, 50, or 100 mils.
The cushion pad 246 provides a cushion for the comfort of the person resting on the massage table. Non-exclusive examples of suitable materials for the cushion pad 246 include urethane foam, foam rubber, and memory foam. In non-exclusive embodiments, the cushion pad 246 has a thickness of approximately 1 inch, 1.5 inches, 2 inches, 2.5 inches, and 3 inches.
Additionally, in alternative, non-exclusive embodiments, the thickness of the cushion pad 246 is at least approximately 1.5, 2, 2.5, 3, or 4 times greater than the thickness of the support pad 242.
The covering 248 secures the cushion pad 246 to the border flange 36 and provides a protective covering for the cushion pad 246. Non-exclusive examples of suitable materials for the covering 248 include leather, plastic, cloth, sheet vinyl and urethane artificial leather.
FIG. 3 is a simplified bottom perspective view of another embodiment of a massage table 310 that is similar to the massage table 10 described above. However, in this embodiment, each of the table tops 322A, 322B includes one or more runner supports 350 that provide additional support for the table tops 322A, 322B. The design of the runner supports 350 can be varied. In FIG. 3, each of the table tops 322A, 322B includes a pair of spaced apart runner supports 350 that extend between and that are fixedly attached to the left side 336C and the right side 336D of each border flange 336. Alternatively, for example, each of the table tops 322A, 322B can include more than two or less than two runner supports 350 and/or one or more of the runner supports 350 can extend between the front side 336A and the back side 336B of the border flange 336.
In one embodiment, each of the runner supports 350 is a rectangular shaped beam. Alternatively, the runner supports 350 can have another shape or configuration.
