United States Patent 3,478,738 BATHING BOOT WITH MEANS TO MASSAGE FOOT Max S. Altman, 362 Knowlton Ave., Kenmore, N. 14217, and James V. Cox, West Seneca, N.Y.; said Cox assignor to said Altman Filed July 15, 1966, Ser. No. 565,531 Int. Cl. A61h 9/00, 35/00; A61m 31/00 U.S. Cl. 128-66 16 Claims ABSTRACT OF THE DISCLOSURE A boot for bathing a foot including a sole, a lower body portion extendin-g upwardly from the sole and an upper body portion extending upwardly from the lower body portion, a seal in the form of a downwardly extending flap proximate the upper edge of the upper body portion, a removable resilient insole Within the boot, a strap for tightening the boot proximate the junction of the lower and upper body portions, and a strap proximate the upper edge of the upper body portion for tightening the upper edge of the upper body portion around the leg.

The present invention relates to an improved boot which is used for bathing the feet.

In the past various types of boots have been devised for bathing feet. These boots, which are adapted to contain a liquid, are generally in the shape of an overshoe and have provisions for sealing the cuff to prevent liquid from escaping from the boot. It is with an improvement in boots of the foregoing type that the present invention is concerned.

It is one object of the present invention to provide a foot bathing boot which includes an improved seal for preventing spillage of the liquid contained therein, either when a person is walking or lying down, without requiring extensive manipulations in securing the seal relative to the leg of the wearer. A related object of the present invention is to provide an effective seal for a boot of the foregoing type, said seal, while being highly ecient in minimizing leakage, still permitting the foot to be inserted and withdrawn in au extremely convenient manner, almost as if the seal were nonexistent.

Another object of the present invention is to provide an improved foot bathing boot which is capable of causing the liquid contained therein to produce a gentle massaging action when a person walks, thereby aiding in the removal of deteriorated tissue, stimulating blood circulation, and washing wounds.

A further object of the present invention is to provide a foot bathing boot which in addition to being lightweight has a relatively high insulating effect for retaining heat or cold. Other objects and attendant advantages of the present invention will readily be perceived hereafter.

The improved foot bathing boot of the present invention includes a lower portion for receiving the foot and an upper portion for encircling the lower portion of the leg of a person. The boot is fabricated from suitable impervious plastic material which is sufficiently strong to contain foot-bathing liquid. Insulation is provided so the boot will retain heat or cold, thereby obviating the neces- ICC sity for frequent liquid changes. A ilap is provided proximate the upper cuff of the -boot for acting as a seal to prevent spillage of liquid, either while the wearer is walking or lying down. The flap provides a highly ecient seal without requiring extensive manipulations in placing the flap in sealing position. In addition, the ap does not in any way interfere with the inserting and removing of a foot from the boot. A removable sponge-like insole serves a plurality of functions, namely, as a nonslip device, as an insulator, as a cushion to prevent undesired pressure on the 'sole of a persons foot, and as a sanitary aid inasmuch as Yit is removable and disposable. However, the most important features of the resilient sponge-like insole is that it provides a whirlpool-type massaging effect. In this respect a strap is provided across the instep of the boot to restrict the boot across the instep of the foot. Therefore, asa person walks he tends to compress the sponge-like insole and the liquid contained therein is forced into the remainder of the boot. However, since the strap restricts the volume of the boot across the instep of the person, the liquid must flow relatively fast through this area, thereby providing the massaging effect with a Whirlpool action. When the person lifts his foot from the door, the sponge will tend to return to its original shape thereby pulling liquid into it and thereby providing a further whirlpool action. The various aspects of the present invention will be more fully understood when the following portions of the specification are read in conjunction with the accompanying drawings wherein:

FIGURE l is a side elevational view of the improved foot bathing boot of the present invention;

FIGURE 2 is a top plan View of the lboot;

FIGURE 3 is a schematic view of a plastic insert which may be placed in the boot; and

FIGURE 4 is a view, partially in cross section, taken substantially along line 4-4 of FIGURE 1.

The improved foot bathing boot 10 of the present invention includes a lower body portion 11 for containing a foot and an upper body portion 12 for encircling the lower portion of the leg. A sole 13 is attached to the lowermost part of lower body portion 11 by means of a heat sealed seam 14. The body of the boot consisting of portions 11 and 12 is fabricated from a single piece of material having a heat sealed seam 15 extending vertically along the front of the boot. A grommet 16 is inserted near the toe of the boot. This grommet is for mounting the boot on a hook for drying. All of the above mentioned seams are Water-tight and the material of the boot is water impervious.

'I'he above-mentioned portions 11 and 12, which form the wall of the boot, are fabricated from a quilted vinyl plastic material consisting of outer plastic layer 17 and inner plastic layer 18. Heat sealed seams 19, in the form of waves overlapping at their crests, join the inner and outer layers to each other to form air pockets 20. A brous polyester material 21 is sandwiched between outer layer 17 and inner layer 18 to provide body to the boot and also provide an insulating effect.

A plastic liner 22 is located in contiguous relationship relative to inner layer 18 and has its upper edge secured to said inner layer 18 at heat sealed seam 23 which encircles the upper portion of the boot proximate cuff 24.

The lower edge of liner 22 is joined at heat sealed seam 14, and the front edges of liner 22 are joined at heat sealed seam 15. It is to be noted that a space exists between liner 22 and inner layer 18 and this air space also functions to provide a certain amount of insulation. Plastic liner 22 also improves the leakproof quality of the boot.

The above described construction of the wall is also found in sole 13 which consists of an inner liner 22', an outer layer 17', and an inner layer 18', with seams 19 joining the inner and outer layers to provide air pockets 20', the edges of sole 13 being attached to the lower body portion 11 at heat sealed seam 14. A fibrous polyester material 21 is located in pockets 20. The numerals depicting various portions of the sole and designated by a prime are analogous to the same unprimed numerals described in detail above relative to the wall of the boot.

The upper body portion 12 is formed into a cuff 24 which consists of the entire thickness of the wall doubled back on itself with the lower portion heat-sealed to the remainder of the wall at seam 23. This causes the upper edge 26 to be rounded to minimize chang which may occur as a result of friction against the leg of the wearer. In addition, the doubling over of the wall at the cuff gives the boot greater body in this area.

The boot 10 includes an improved liquid seal construction for preventing ejection of liquid when a person walks and when the boot is worn while lying down. In this respect, a flap 27 (FIGS. 2 and 4) is provided with its upper portion being heat-sealed to upper body portion 12 at seam 23. Flap 27 may be fabricated from any suitable flexible plastic sheet material. As can be seen from FIGURE 4, flap 27 is essentially of inverted frustoconical configuration. The lower edge 28 of ap 27 is unattached and free. Flap 27 is continuous throughout its circumference except for the portions thereof adjacent seam 15, said portions terminating at ends 30 overlapping at 31 proximate seam 23. The fact that flap 27 has the foregoing discontinuity permits a wearer to insert and remove his foot without any interference from flap 27.

In order to provide a seal when the boot 10 is being worn, a strap arrangement 32 is provided which in this instance is known under the trademark Velcro and consists of a strap portion 33 having one end attached to the boot by a suitable rivet (not shown). The other portion of strap arrangement 32 consists of a strap 34 having an end attached to thewall of the boot by rivet 34". The other end of strap 3'4 is free. Strap 33 contains loops which receive tiny hooks on strap 34. The hooks and loops are selectively engageable and detachable.

Whenever the fastener 32 is closed to draw the cuff 24 tightly around the leg, as shown in FIGURE l, the ends 30 of ap 27 will lie in overlapping relationship to thereby provide an effectively continuous iiap for sealing liquid against leakage from the boot. It is to be especially noted that flap 27 is continuous in area 35 proximate the rear of the boot to provide a liquid barrier against leakage when the wearer is lying down. When strap 32 is unfastened the ends 30 of flap 27 will return to the position shown in FIGURE 4 to permit the foot to be removed without interference from the ap. The lower portions of iiap 27 proximate edge 28, being the smallest portion of the inverted frustoconical configuration, will tend to hug the leg when strap 32 is fastened and therefore not only tend to minimize leakage of liquid but also act as a heat barrier to tend to minimize loss of heat from the liquid within the boot.

A sponge-like insole 36 of the same general configuration in plan as sole 13 is selectively removable from the boot. Insole 36 performs a plurality of functions. It acts as a non-skid device and as a cushion for the sole of the foot. In addition, it retains moisture and heat proximate the sole of the foot. Furthermore, it can be disposable and therefore act as a removable sanitary cushion. However, its most important function is to act in conjunction with insole strap 37 to provide a whirlpool effect. Strap 37 may be the same type as noted above, namely, one known by the trademark Velcro having a strap portion 38 and a base portion 39. Portion 38 includes a plastic portion 38 secured to the wall of the boot by circular heat seal 33'. Velcro loop portion 38" is secured to strap 38 by a rivet (not shown) analogous to rivet 41' noted hereafter, Strap 39 includes a portion 39" secured to the boot wall by circular heat seal 34'. Velcro hook portion 40' is secured to strap 39 by rivet 41.

As can be seen from FIGURES 1 and 2, the strap 37 can be tightened across the instep of the wearer to restrict the volume of the boot about the arch and instep. Therefore, when a person bears down on the sole 13, as he would during taking a step, liquid will be expelled from sponge 36. Because of the restriction of the volume of the boot about the instep the liquid will travel with relatively high velocity away from the lower body portion 11. Conversely, when pressure is relieved from insole 36 it will tend to expand and suck liquid into lower body portion 11 past the restriction provided by strap 37 with a relatively high velocity. The foregoing action will provide a Whirlpool effect which provides a plurality of beneficial actions, namely, a gentle massaging which stimulates blood circulation and a iiow of liquid which tends to remove dead tissue. In addition, if the liquid is medicated, the medicine will be forced into the wounds incidental to the washing action provided by the liquid,

If the boot is to be used in an institution, such as a nursing home, a plastic liner 40 of the general contour of the inside of boot 10 may be inserted into the boot with sponge 36 being inserted within boot 40. This permits one boot to serve different patients. If the sponge 36 is placed between liner 40 and the boot, the above described whirlpool effect will still be obtained because the sponge 36 produces a variable volume around the foot, as described above.

In addition, the liner permits the boot to provide dry cold. In this respect, crushed ice and water may be placed in the boot itself and the foot may then be placed in plastic liner 40 which is thereafter inserted into the boot with the foot, thereby causing the ice water to surround the plastic liner 40.

The above description has referred to vinyl plastic material which is the common name for polyvinyl chloride, and all plastic parts of the boots are made from this material.
