FIELD OF THE INVENTION This invention relates to a portable vertebral column support and, more particularly, relates to a vertebral column support for use in chairs and the like which may be transported by the user in an inconspicuous manner by camouflaging the support as a commonly known article which is normally carried, such as a briefcase, purse or the like.

BACKGROUND OF THE INVENTION People who have recurring back problems are often confronted with having to sit in uncomfortable seating which does not adequately support their vertebral column. As a result, and after a prolonged sitting in such seating, an uncomfortable feeling begins to develop in the back muscles of the occupant of the seat and no matter how the occupant reorients himself relative to the seat, the uncomfortable feeling in the back muscles cannot be remedied. As a result, the occupant is forced to leave the uncomfortable seat and move about for a certain period of time before returning again. This becomes an embarrassing problem particularly in theaters where it is not convenient for the occupant of the seat to get up and move about. Further, the problem also arises in modern day automobiles wherein the seats areoften inclined at an angle which is aggravating to the back muscles of some occupants thereof. As a result, it may be necessary for the occupant, if he is driving the automobile, to pull off the road and stop the car so that he may get out and walk around a little bit to ease the discomfort in the region of the 5. To provide a'support which needs no adjustment, but which, through its simplicity, fits the majority of people and conditions.

back. On our modern day freeway system, this is neither always convenient to do nor is it safe to do unless it is at a rest area provided along the highway for stopping and resting. As a result, the occupants attention is diverted from the road for short periods of time while trying to reorient himself in the seat to eliminate the pain and discomfort in the back area, resulting in an obviously dangerous condition.

Further, it is desirable to provide a portable vertebral column support which is not worn by the user but is, instead, carried by the user in an inconspicuous manner so that the device will be readily available if and when desired but is not otherwise burdensome. I

Accordingly, the objects of this invention include:

1. To provide a portable vertebral column support which may be carried in an inconspicuous manner by a person suffering from frequent back problems by camouflaging same as a commonly known article, such as a man s briefcase or lady's purse.

2. To provide a portable vertebral column support, as aforesaid, which is comprised of readily available, light weight, components which are easily assembled into a light weight, easily portable form.

3. To provide a portable vertebral column support, as aforesaid, which will permit the replacement of the rigidifying support elements should they become broken or damaged.

4. To provide a portable vertebral column support, as aforesaid, which is inexpensive to manufacture and easy to maintain in a satisfactory condition.

SUMMARY OF THE INVENTION The objects and purposes of the invention aremet by providing a portable vertebral column support for use v the envelope may be provided with an auxiliary pocket along one side of the envelope for holding papers and the like without intefering with the functioning of the vertebral column support. Further, the envelope may be provided with a strap or snaps to permit the outer longitudinal edges of the envelope to be brought together and maintained in closed I relationship relative to one another by the strap.

DETAILED DESCRIPTION I FIG. 1 illustrates the portable vertebral column support 10 positioned between the back of an individual M and the curved portion 11 of a seat S. The curved portion 11 of the seat S has a tendency to resiliently return to the normal broken line position and projects into the back of the individual, which aggravates any swayback or lordosis of the individual M. However, by placing the portable vertebral column support in the position illustrated, the vertebral column of the individual M will be supported in a straight and upright position to alleviate pain and discomfort.

One desirable form of the portable vertebral column support 10 comprises a pair of elongated sheets of

flexible material

12 and 13 fastened together in any convenient manner, as by riveting, welding, sewing, or with glove snaps, at the peripheral edges thereof along

seams

16, 17, 18 and 19 to define an envelope 20. The

sheets

12 and 13 are of sufficient length to engage the desired portion, usually the lower and middle back muscles, of an average individual which serve to support the vertebral column in an upright position. An opening 21 is provided adjacent one end of the envelope 20 to permit access into the interior thereof. In this particular embodiment, a zipper 22 of any convenient variety may be provided to close the opening 21 but permit ready access as desired to the interior of the envelope 20.

In this particular embodiment, the

sheets

12 and 13 are divided into three

longitudinal sections

23, 24 and 25,-which are in this embodiment of approximately equal width but may be varied as desired. Said sections are separated by seams 26 or 27 formed as convenient, as by sewing, welding or riveting. The spacing between the seams 26 and 27 are preferably of a width suff cient to span the average width of the protruding portion of the vertebral column of the individual M so that the

sections

23 and 25 engage the portions of the :back of the individual M on opposite sides of the :vertebral column. Since the

sections

23 and 25 directly engage the back of the user closely adjacent to but on opposite sides of the vertebral column, the

support 10 is thus provided with a width approximately no greater than the width of the average users back, as clearly illustrated in FIG. 3. The

seams

18, 17, 26 and 16, 17, 27 define a pair of pockets 28 and 29 (FIG. 3),

respectively.

Rigidifying

members

31 and 32 may be inserted into the

pockets

28 and 29 respectively, in the

sections

23 and 25 through the opening 21. The

rigidifying members

31 and 32 may be made of a thick (V4 inch) plastic or wood or other light weight material having a rigid, or at least stiff, characteristic. They may be fixed permanently in place if desired or made removable through openable closing means associated with the as either a briefcase or other flat or folded object normally carried by an individual.

OPERATION In use the support is opened to its spread out position as shown in FIGS. 2 and 3 and is placed between the users back and the back of the seat in which he is sitting, preferably at the lower portion of both thereof as shown in FIG. 1. The support 10 is arranged so that the protruding portion of the vertebral column is received into the space between the stiffeners. namely the space 24 shown in FIGS. 2 and 3 and corresponding spaces in the other embodiments of the support.

The portions of the individual's back on either side of the vertebral column engage the

rigidified sections

23 and 25 of the support 10. Thus, the

rigiditied portions

23 and 25 serve to preserve a flat lower back, instead of allowing the seating to effect a forward thrust into swayback or lordosis. Thus, the individual may be seated in a seat S wherein the curved portion 11 thereof will be sufficient to aggravate the persons swayback or lordosis, and lead to pain. However, through the utilization of the portable vertebral column support 10, the back muscles are adequately supported to maintain the vertebral column in an erect posture and thereby make it possible for the individual to remain seated in the seat for longer periods of time without being subjected to pain and discomfort. The flexibility of the central panel 24 permits the support to curve as needed to place the stiffened

sections

23 and 25 in the proper position against the users back.

ALTERNATE CONSTRUCTIONS The portable vertebral column support 10A illustrated in FIG. 4 will be referred to by the same reference numerals designating corresponding parts of the support 10 but with the suffix A added thereto. The portable vertebral column support 10A illustrated in FIG. 4 is identical to the embodiment illustrated in FIGS. 2 and 3 except that an additional sheet of flexible material 33 is fastened to the sheet 12A along the peripheral edges thereof which correspond to the

seams

16, 17, 18 and 19 illustrated in FIG. 2. Only two seams 16A and 18A, however, are illustrated in FIG. 4. The

pockets

28A and 29A may be, as desired, permanently closed with the

stiffeners

31A and 32A permanently therein or they may be openable and closable by any convenient means, such as means similar to the zipper 22 of FIG. 2. The additional sheet of flexible material 33 defines with the sheet 12A a pocket 34 having a sufficient capacity to carry a plurality of papers or other flat objects. An opening 35 is provided adjacent one end of the sheet 33 to permit access into the pocket 34. if desired, a zipper may be provided to open and close the'opening 35 as desired. Alternatively, a single zipper across the end of support 10A, similar to the zipper 22, may be used to open and close simultaneously both the opening 34 and the

pockets

28A, 29A.

The portable vertebral column support 108 illustrated in FIG. 5 will be referred to by the same reference numerals designating corresponding parts of the support 10 but with the suffix B added thereto. The portable vertebral column support 108 illustrated in FIG. 5 is identical to the support illustrated in FIGS. 2 and 3 except that a strap 37 has been fastened, as at 38, adjacent the seam 16B to the sheet 128 adjacent one edge thereof. The free end 39 of the strap 37 is provided with a fastening device 41 which is cooperable with a mating fastening device (not shown) fixed to the sheet 123 adjacent the seam 188. The section 24B is flexible and defines a hinge. Thus, the support 108 can be folded in half about the hinge section 24B and the fastening device 41 secured to a fastening device (not shown) adjacent the seam 188 so that the support is maintained in a folded condition. Alternatively, the strap 37 may, if desired, be replaced or supplemented by detachable fastening means, such as snaps, affixed between the scams, or surfaces near the seams, 16B and 188. Thus, the portable vertebral column support 108 can be camouflaged, if desired, as a ladies purse or other article normally carried by an individual.

As a still further modification (FIGS. 6-8) a single sheetof flexible material such as leather, cloth, plastic or the like indicated generally at 41 is folded back upon itself to provide a bight 42 and free edges 43 and 44, said latter being preferably hemmed or otherwise finished to improve the appearance.

A plurality of relatively stiff slats 46-48 is provided at one side of the unit and a further plurality of similar slats 51-53 is provided at the other side of the unit. In the illustrations of FIGS. 6 and 7 each group is shown as comprising three slats each and such has been worked out as a highly advantageous number thereof. However, such number may be increased or decreased as desired with the corresponding decreases or increases in the width of each thereof to provide for various operational and/or manufacturing objectives and conveniences as desired. In the present embodiment said slats 46-48 and 51-53 are made of wood but they may be of plastic or other stiff material as desired. Said slats are fastened to the adjacent side 41A of the sheet 41 in any convenient manner, such as by a suitable adhesive.

Placed between the said slats and the other side 41B of the sheet 41 are two piecesof padding 54 and 56. Same may be of any desired thickness, preferably, however, not so thick as to destroy the essential compactness and thinness of the finished article. It has been found that foamed polyethylene of approximately oneeighth to three-sixteenths inch in thickness is effective.

In the drawing there is shown a single piece of such padding, as the piece 54 between an entire adjacent group of slats as the group 46-48. It will be evident that if desirable, it is equally feasible, though of less manufacturing convenience, to provide individual pieces of padding between each of said slats and the side 418.

The free edges 43 and 44, as well as the adjacent ends, are afflxed together in any convenient manner, such as by. sewing, by an adhesive or heat sealing as appropriate.

As before, a zone 57 is provided between the two groups of slats corresponding to the space 24 between the

slats

23 and 25 of the embodiment shown in FIG. 3 for the reception of the protruding portion of the vertebral column of the user in the same manner as above outlined.

The manner of use of this form of the invention is the same as that above set forth in connection with the embodiment of FIGS. 2 and 3 and hence needs no further description. It is of particular note here, however, that with padding on only one side of the stiffeners, the user may place either a hard surface or a soft surface against his back as desired. This provides further flexibility in use and will further extend the usefulness of the support.

Although particular preferred embodiments of the invention have been disclosed in detail for illustrative purposes, it will be recognized that variations and modifications of the disclosed apparatus, including the rearrangement of parts, the use of more than three longitudinally joined and hinged sections, lie within the scope of the present invention.
