ARTIFICIAL FOOT.
Application filed. November The invention relates to improvements in artificial feet to support the natural foot of a short limb as an extension thereof and has for its principal object the provision of an artificial foot that presents the appearance of a natural foot, and serving in the place of the natural foot and permitting it to be worn without weariness to the wearer, the device having four motions, a pivotal motion front and back, and a slight canting motion to right and to left, thus simulating the action of a natural ankle oint.
lhe invention also has for its object the provision of a device composed of sections articularly connected and comprising upper and lower sections, that is, a platform resembling a human foot and a heel support supported on said platform and shaped to sustain the natural foot, said platform and heel support being adapted to move relatively to one another in the act of walking.
Another object of the invention is the provision of aconstruction of foot made in two sections, the front or toe section being so connected with the remainder of theplatform that it will oscillate to a limited degree to simulate a toe joint. i
The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings in which- Figure l is a side view in elevation of the improved artificial foot showing the natural foot in broken lines in position thereon,
Figure 2, a bottom plan View,
Figure a view similar to Figure l with the heel and back portion of the artificial foot in horizontal section,
Figure l, a transverse sectional view on a plane indicated by the line k4: of Figure 3,
Figure a fragmental detail on an en larged scale on a plane indicated by the line 55 of Figure 3, and I V Figure 6, a transverse sectional view of the heel support on a plane indicated by the line G6 of Figure l.
In the drawings similar reference characters will be used to designate corresponding parts throughout the several views.
l he artificial foot comprises a'platform l made up of two sections designated 2 and 3 that are secured to a plate a of resilient material such for instance as spring steel, the adjacent faces of tire parts 2 and 3 being provided with mating recesses and 6 in which recesses is mounted a block '7 of 5, 1925. Serial-No. 67,052.
cushion material such forinstance as rubber. The lower portions of the parts 2 and 3 under the recesses 5 and G are formed with oppositely inclined faces 8 and 9 to permit a slight movementof the two members 2 and 3 to simulate the toe joint of a natural foot. I I
The upper face of the heel portion of the platform 1 is provided with a transverse groove 10 in which is seated a bearing sleeve 11 that forms the bearing for a pivot pin 12, said sleeve being secured in position in the platform 1 by means of an eye bolt 13 011 which is secured a nut let seated in a recess 15 in the under side of the platform 1.
.The upper face of the heel portion in said platform 1 at the rear of the transverse groove 10 is substantially horizontal as shown at 16, while the face in front of the transverse groove 10 is upwardly inclined as shown at 17 Arms 18 are pivotally mounted on the pivot pin 12 and provided with elongated slots 19 to receive said pivot pin. 20 is'a heel support secured between arms 18 by means of transverse bolts 21, the side faces of said heel support 20 being recessed as shown at 22 to receive arms 18, 23 indicating recesses in the side faces of heel portion of platform 1 at the lower ends of said arms 18. j
The under side of the heel support 20 has two faces 2st and 25 providing an offset shoulder 26, and 27 is a block of cushion material, such for instance as rubber mounted between the upper face of the platform 1 and the under side of the heel support 20. By this construction it will be apparent that when the device is in use, the pivotal connection heretofore described between the platform and the heel support will permit forward and backward swinging of the heel support relatively to the platform to simulate the pivotal movement of the ankle joint of a natural foot, and that the elongated slots 19 in the arms 18 will permit canting of the platform 1 relatively to the position of the support 20 to right or left to accommodatethe a 'tificial foot to unevennesses of the roadway, this action also being similar to the action of the ankle joint of a natural foot.
As shown in the drawings the arms 18 are extended above the heel support 20 to form side supports for the natural foot and leg indicated in dotted lines in the drawings,
