SUMMARY OF THE INVENTION

The present invention embodies the ultimate in the ergonomic design of a gripping and traction surface. The present invention is a device to enhance the gripping or traction of articles to which it is formed or attached, namely footwear, handwear, and mechanical gripping or

SUBSTITUTE SHEET (RULE 26) traction devices. More particularly, the device is a gripping and traction pattern, formed as an integral part of a shoe sole, that is based on the natural footprint of a human foot. The bottom of the human foot- is not a flat surface, but a combination of various anatomical elements of differing size, shape, and contour. The present invention is molded as an integral part of an elastically deformable and compressible outsole, and incorporates the elements and

characteristics of	the human	foot.	The	sole has multiple
10 projections which	stand away	from	the	base of the	sole,
thereby creating	adjacent raised	and	recessed	areas .
Projections corresponding to	the	five	toes, and	large C

projections approximating the ball and heel of the foot, are _c formed in proportion to the actual anatomy of the human ’ c

foot, thereby creating projections of varying heights.

!*

These projections create recessed areas corresponding to the _careas between and behind the toes as well as other recessed £ areas of the human footprint. These recessed areas allow C the ground-engaging projections to adequately deform depending on the force exerted on the sole by the wearer.

The outer surface of the outsole is textured with small ridges to approximate the skin pattern of the human foot to further improve traction.

Additionally, the invention can be used for the outer gripping surfaces of gloves or mechanical gripping devices.

The palm and finger surfaces of gloves are covered with a thin, elastically deformable material incorporating the shape, contour, and features of the human handprint. The

SUBSnTUTE SHEET (RULE-26) present invention is envisioned not only to be applicable to shoe soles and gloves for wear by humans, but also to the makers and users of movable automated equipment, such as robots, where gripping traction is desired/ Additionally, the inventive concept can be expanded to provide devices for superior traction and gripping power for numerous applications, such as gripping tools, prostheses, or any other similar device.

OBJECTS OF THE INVENTION

CM , The principal object of the invention is to enhance the gripping or traction of articles to which it is formed or attached, namely footwear, handwear, and mechanical gripping 15 or traction devices.

A further object of the invention is to provide a C <

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Figures 1, 2, and 3 shows a shoe sole 10 constructed from an elastically deformable material. The sole has a base surface 12 that is substantially smooth and flat with a front portion 14 corresponding to the toe area of the sole and a rear portion 16 corresponding to the heel area of the sole. Molded as an integral part of the sole are projections 18, 20, 22, 24, 26, 28, 30 which extend beyond the base surface 12 in varying shapes, contours, and heights .

O τΟ <= r* o

Q

Q <

Figure 1 shows, at the front portion of the sole 14, five projections 18, 20, 22, 24, 26 the size, shape, and location of which correspond to that of the bottom tips of the toes of a human foot. Other large projections 28, 30 cover a substantial part of the sole, from the heel area to

SUBSTITUTE SHEET (RULE 26) the area of the sole corresponding to the ball of the foot.

The projections are not necessarily -uniform in the 5 heights 24a, 28a, 30a by which they extend from the base surface 12, as seen in Figure 5. The height of any projection varies in relation to the variation in the threedimensional anatomy of the human foot. The variation in projection height can also be based on the respective magnitude of force applied to the respective areas of the sole during walking or athletic activity. For example, the projection height 28a at the heel is greater than the projection height 34a at the instep. This variation in projection height, based on the anatomy of the foot, results in some areas on the outsole where little or no projection occurs, leaving gaps and recesses 32, 36 as shown in Figure

1. These recessed areas 32, 36 correspond to the areas of a human foot that do not necessarily directly contact the ground when a person is standing, such as the instep, and the areas between and behind the toes. These recessed areas of the human foot are very important to the acts of walking or running, however, because they allow the toes to grip the ground or floor surface when force is applied when walking, thereby creating superior traction. Similarly, the recesses

32, 36 in the invented sole allow the ground-engaging projections to adequately deform based on the force or stress applied by the wearer of the shoe. This deformation also supplies superior traction and a more natural feel for the wearer of the shoe.

ΔΡ/Ρ/ 9 7/01012

SUBSTITUTE SHEET (RULE 26)

Figure 4 shows an enlarged view of the outer surface of the projections 18, 38. Integrally formed on all groundengaging outer surfaces of all projections are a plurality of small ridges 40 that simulate the characteristic print of human skin. These ridges allow the ground-engaging surfaces of the elastically deformable sole to better grip the walking platform thereby creating superior traction.

The best mode of carrying out the invention is accomplished where the gripping and traction surface is an integral part of the shoe sole, which is constructed of an £

elastically deformable material that is common to athletic shoes, such as rubber, PVC, polyurethane, or any suitable ^csynthetic plastic substance. The sole is cast or injection _cmolded directly to the upper of the shoe to integrally incorporate all of the features of the gripping pattern, including the base, projections, recesses, and ridges. ALTERNATIVE EMBODIMENTS

The present invention can be applied not only to footwear to be worn by humans, but also to any application where gripping traction is required, such as on gloves, tools, or leg or arm mambers of automated machinery or robots. The development of technologically advanced machinery capable of carrying out mechanical tasks continues to expand. The invented gripping and traction pattern can be attached to any element of a device or machine in which superior gripping ability or traction is desired.

SUBSTITUTE SHEET (RULE 26)

Figures 6-11 show other embodiments including the use of hand or finger-shaped projections on the gripping surfaces of gloves or other gripping devices, such as the mechanical hands of robots, automated machinery, or gripping tools.

Figures 12 and 13 show another embodiment of the invention as applied to the gripping surface of a mechanical device. The device has ridges 78 formed directly on its gripping surfaces 76, and does not have projections formed on its surfaces. These ridges 78 are formed in a configuration which approximates the characteristic print of human skin.

Palm	projections 44	<a

cover a portion of the surface of the glove corresponding to 20 the human palm. On each of the four finger portions of the glove are separate and distinct projections 46, 48, 50 corresponding to the three segments of each human finger formed by a knuckle and two joints. Projections 52 and 54, similar in shape and arrangement to the inner surface of the human thumb, extend from the base surface 42 of the thumb portion of the glove.

Because these projections are separate and distinct, gaps 47, 49, 51, 53 are created on the areas of the glove

SUBSTITUTE SHEET (RULE 26) surface between projections. These gaps allow proper closure of the glove around an object to be grasped and allow adequate deformation of the deformable projection surfaces, thereby creating superior traction and gripping ability.

Alternatively, the projections extending from the base surface 42 of the glove 41 may not be separate and distinct, but may be unitary, as shown in Figure 7. A large, single projection 74 extends from the base surface 42 of the glove 41. This projection corresponds to the shape and c

configuration of a human hand. The outer surface of c

projection 74 has integrally formed ridges 72 that are arranged in a manner simulating the characteristics of human 15 skin. Similarly, the projections extending from the base surface 12 of the shoe sole 10 may not be separate and distinct, but may be unitary and comprise a single large projection which approximates the size, shape, and arrangement of a human foot.

Figure 9 shows a mechanical hand as would be used with a robot or a piece of automated machinery. Projections 56,

58, 60, made of any suitable elastically deformable and compressible material, such as that used for athletic shoe soles, and attached to the mechanical hand by an adhesive, extend beyond the surface 55 of the hand. These projections 56, 58, 60 correspond to the shape and arrangement of human fingers. Similarly, projections 66 corresponding to the shape and size of the palm are attached to the palm portion

AD/D/ Q 7 / n

SUBSTITUTE SHEET (RULE 26) of the mechanical hand, and projections 62, 64 approximating the shape of a human thumb are attached to the mechanical hand and extend beyond the surface 55 of the mechanical hand.

Figure 11 shows a mechanical gripping device with projections 70 approximating the shape of human fingers adhesively attached to the gripping surfaces of the tool. The projections, made of any suitable elastically deformable material, do not cover the entire portion of the gripping surface, thereby leaving gaps 71. These gaps 71 effect

t.. proper closure of the gripping mechanism around the object to be grasped. Figure 10 discloses another mechanical gripping mechanism. The gripping surfaces are covered with an elastically deformable material 68 to create the requisite gripping ability.

Figures 6-11 show that on all outer surfaces of all projections are integrally formed a plurality of ridges 72.

These ridges allow adequate deformation of the elastic projection material when force is applied to their surfaces, thereby creating superior traction and gripping ability. These ridges are formed and arranged in a pattern which approximates the swirls, whorls, loops, or other characteristics of human skin.

The ridges 40, 72 formed on all gripping and traction surfaces described are not necessarily spaced evenly on each projection nor are the ridges necessarily uniform in their

0 I 0 / L 6 Zd/dV

SUBSTITUTE SHEET (RULE 26) width or depth. Additionally, these ridges can be arranged in a manner simulating the skin characteristics of any creature, not merely those of human skin.

Another embodiment of the invention involves arranging the ridges on the gripping and traction surfaces of the projections in a pattern of concentric circles, concentric ovals, spirals, or other geometric configurations.

Similarly, the present invention can provide gripping and traction surfaces with projections arranged corresponding to the anatomy of a foot, hand, finger, paw, claw, or any surface-engaging appendage of any creature.

c

Further, the material of which the present invention is ▼ c

formed need not be elastically deformable. The gripping and traction pattern can be formed of any material suitable for ^cuse on the article to which it is to be attached; for example, the pattern for use on the sole of a shoe can be made of leather.
