Abstract
Abstract of the Disclosure A shoe sole is formed in the heel with a cavity that is compressible to relatively small volume when the heel is pressed down and that is normally of somewhat larger volume. Structure associated with the cavity and exposed at an outer surface of heel expels liquid from the cavity when the heel is pressed down and aspirates liquid in contract with the outer surface when the heel is lifted. An elastically compressible sponge body fills the cavity. This cavity can be a pocket open at the outer surface of the heel or it can be offset from the surface of the heel in which case at least one passage extends between the cavity and the heel outer surface. The cavity can also be empty and offset form the surface of the heel with at least one passage extending between the cavity and the heel outer surface.
Description
ANTISPATTER HEEL FOR ~HOE SOLE
SPECIFIC~TIO~
Field o the I~e~tlon : ~he present inven~ion relates to a shoe sole. More partiaularly this inven~ion concern~ a heel ~or ~u~h a ~hoe 801~.
Ba~kground o~ the In~ention : A standard ehoe sole.has is.entirely made of a r~la-: tively hard but flexible wear-resistant materia}. The mater1.al may be a neoprene-type synthetic rubber, leather, or even a closed cell foam. The sole must resist wear while protecting the wearer's ~oot ~rom anything on the ground.
German patent document 2,800,593 describes a sho~ sole which iB provided with openings in the ground-enqaging lower surface whioh are open internally in the shoe through an air-permeable lay~r of as leather, fabric, a kni~, or a ~elt. Whilesuch a structure provides Pxcellen~ aeration of t~e wearer'~
foot, it mean~ that any water ~he wearer s~eps in will soak right into the shoe to his or har foo-In German patent do~umen~ 2,731,533 a sports shoe is descri~ed having a sole made o~ a block of rubber with a d~mpinglayer of fin~-pore rubberO The s019 iS formed with polygonal-shaped grooves which only extend through a portion of th~ mainbody of the rubber shoe, not into the damping layer.
All such shoe6 have the considerable disadvantage that if the wearer steps in a puddle, the liquid hang~ on the heel of the shoe and will be thrown up on the back of the wearer's leg as he or she llfts this ~oot. Thus even though the footwear may protect the wearer's feet from getting we~, water spattered up in this manner will land on the wearer's legs and/or clothing.
Ob~ects o~ the Invention It is therefore an object of the present invention to provide an improved shoe sole.
Another ob~ect is the provision of such an improved shoe sole which overcomes the above-given disadvantages, that is which prevents water that is being stepped on from being picked up and thrown up on the wearer's legs.

~ Summary~of the In~ention ,; :
A shoe sole according to this invention is formed in the heel with a cavity that is compressible to relati~ely small volume when the heel is pressed down and that is normally of somewhat larger volumeO Structure associated with tha cavity and exposed at an outer surface of heel expels liquid ~rom th~ cavity : 785~MR
when the heel i9 pressed down and a~pirates liguid in contact with the outQr surPace when the heel is li~'t~d.
~ hus as the person put~ his foot down, invariably hael first, the cavity structure will be compreEi~ed and any llquid therein will be expelled. A8 the foot is raised the cavity ~tructure will elastically reassum~ lts original ~hape, thereby aspira~ing any liquid on the sur~ace of the heel 50 that: thi~
liquid cannot be thrown up onto the back of the wearer's leg.
According to another ~eature of this invention an ~lastically compressible ~ponge body ~ill8 the cavity. This cavity oan be a pocket opan at the outer sur~ace of ths heel or it can be offset from the sur~ace o~ the heel in which case ~t lea~t one passage extends between ~he cavity and ~h~ heel outer sur~ace.
Th~ cavity according to this invention can also b~
empty and offsst ~rom the sur~ace of the h~el with at lsast ons passag2 extending between the cavity and the heel outer surface.
In acc~rdance with thi~ invention,the body is an open-cell polyurethane foam having a density o~ between 450kg/m3 and 5SOkg/m3. It can al60 be made o~.a bibulous materiaI such as felt. ~he outer surface can have a vertical rear surface at which the passage opens and/or a horizonta} bottom surfa~ at which the passage opens. In a situation with bo~h advantags~ the pa~sag~ can open at the corner between the rear upright and the bottom horizontal sur~aces.

Brief Descrip~ion of the Dr~wing The above and other objects, features, and a~vantage~
will becom more readily apparent from the following, reference being made to the accompanying drawing in which:
Fig. 1 i~ a side view partly in section through a shoe according to this invention: and Figs. 2 and 3 are views like Fig. 1 of alternative arrange~ent~ in accordance with the invention.
Specific Description As seen in Fig. 1 a shoe sole 1 on a shoe 2 has a heel 3 provided with a moisture-trapping device 4 here con~tituted by an open-cell polyurethane sponye body 6 ~illing a pocket 5 formed at the rear of the heel 3. The sponge 6 is compre~sed and squeezed fairly dry as the wearer's ~oot lands on the rear edge of the heel 3, then expands and sucks in any water adhering to the heel 3 as the shoe 2 is raised~ As a result there will be no free water on the heel 3 that can be tossed up on the back of the wearer's leg.
In Fig. 2 a heel 3' has a device 4' comprised o~ a cavity 7 formed in the heel 3' but cover2d downward by a plate 13 formed with throughgoing perforations 9 that open at thP bottom of the heel 3'. In addition the caYity 7 i~ open backwardly at a rear surface 10 of the shoe and is filled by another polyurethane 7a52MR
sponge 8 o~ a relativ~ly high density of about 500kg/~3l The - plate 13 can be replaceable and relatively durable to avoid - excessiv2 wear to ~he sponge 7, even made Or me~al i~ desircd.
This deviae ~' ~unction~ identically to the device 4 o~ ~lg. 1.
In Fig. 3 a heel 3" i8 equipped with a dev~ce 4" that i~ ~ormed simply as a normally empty cavity 11 that opens via one or more passages 12 a~ the lower rear edge o~ the heel 3"0 The heel 3" i~ ¢ompres~ed ~o that the cavity 11 expels any moi~ture on the down step while a~pirating any moisture a~ it i~ rais~d, an ln Flgs. 1 and Z.
