Filed June so, 1947 Inventor Amzy Orvi/ Shock Patented July 19, 1949 UNITED STATES PATENT OFFICE 3 Claims.
The present invention relates to new and useful improvements in devices for exercising the feet for the purpose of strengthening the muscles at the bottom of the foot and especially at the arch thereof.
More specifically this invention embodies a provision of a disk-like member having its upper surface formed with resilient knobs to produce a massaging effect on the bottom of a foot when placed thereon and to provide the center of the disk with a convexed area also formed with the resilient knobs to effectively engage the arch of the foot.
A further object of the invention is to provide a device of this character of simple and practical construction, which is efiicient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a top plan view, and;
Figure 2 is a sectional view taken on the line 2-2 of Figure 1.
Referring now to the drawing in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of this invention the numeral 5 designates a disk preferably constructed of rubber or other resilient material, the upper surface of the disk being formed with dome-shaped knobs 6 arranged to substantially closely cover the entire area of the disk.
The center of the disk is formed with a pocket 1 in which sponge rubber 8 is inserted to provide a convexed area 9 at the center of the disk, the knobs 6 extending throughout the surface of the convexed area 9.
The s-ponge rubber filler 8 increases the resilience of the central convexed area of the device.
In the use of the invention the foot of a person is placed on the surface of the disk, the knobs 6 yielding under pressure of the foot to thus exercise and produce a massaging effect on the muscles on the bottom of the foot whereby to strengthen the muscles.
The convexed area 9 at the center of the disk projects upwardly upon the surrounding area to thus enter the arch of the foot and subject the muscles thereof to the exercising action.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Having described the invention, what is claimed as new is:
1. A foot exerciser comprising a disk having a pocket at its central portion, a resilient convex pad in said pocket forming a rounded raised portion in the surface of the disk and knobs rising from the entire surface of the disk and, including said raised portion, said knobs being disposed in substantially close relation to each other.
2. A foot exerciser comprising a disk of resilient material and having a closed pocket at its central portion, a resilient convex filler in the pocket elevating the central portion of the disk, and knobs integrally formed on the entire surface of the disk and including the elevated portion.
3. A foot exerciser comprising a member of resilient material having a pocket between the upper and lower surfaces thereof and located substantially in the center thereof, a filler of resilient material in the pocket acting to form a rounded raised portion in the upper surface of the member, and knobs rising from the upper surface of the member and including said rounded raised portion, said knobs being disposed in substantially close relation to each other.
