Description
7~ :
The present invention relates to a profiled outer sole made in a ~old ~or shoes, especially for sport shoes, of rubber or of another material with rubber-elastic properties, especially of synthetic resinous material, with block-shaped or post-shaped pro~iled projections arranged along the lateral sole edges.
- This application is a divisional application of copending application No. 254,362 filed ~une ~, 1976.
It is known in connection with ski-, mountain- or hiking boots to provide the lateral sole edges of the outer sole with block- or post-shaped profiled projections arranged in one or several rows. The distance between the individual ;
profiled projections is thereby approximately as large as the width thereof.
This prior art outer sole offers a sufficient gripping ability and non-slip stability in case of a relatively soft :. .
underground. However, it is not possible with these outer soles having post- or block-profile rows, to make the blocks so small .. .
or the rows of blocks so fine in structure that the slipping safety is assured to a sufficient extent not only with a rela-tively soft underground but also with a relatively harder underground.
; The present invention is concerned with the task to so construct an outer sole of the aforementioned type that this outer sole exhibits excellent non-slipping and standing characteristics for the user.
The underlying problems are solved according to the present invention in that the block-shaped or post-shaped profiled projections laterally delimiting the tread surface of the outer sole are provided with groove-shaped slots extending obliquely to the respective tangential plane tangential to the outer boundary surfaces of the individual profiled projections ' ' I
L7~L
in -the bisecting plane thereof.
The deformability and the number of gripping edges o~ the block- or post-shaped pro~iled projections is increased by the groove-shaped slots. The block- or post-shaped proflled projections or raised portions are therewith also able to adapt themselves readily to small unevennesses of the ground and to produce the desired frictional connection.
It is o~ advanta~e i each of the block- or post-shaped pro~iled projections includes two or more mutually ;
parallel groove-shaped slots and if possible the groove-shaped slots are constructed V-shpaed or roof-shaped with the flanks thereof being open in the direction toward the sole longitudinal ;~
axis. The gripping and slipping safety of the outer sole according to the present invention is still further improved in case of longitudinal and cross loads by the inclined position or roof-shaped construction of several groove-shaped slots.
The outer sole according to the present invention may be constructed with advantage in such a manner that it possesses, in addition to a high non-slipping characteristic, an excellent -', 20 standing ability also with a hard and/or smooth underground such as with hall floors of wood, synthetic plastic material, asphalt, concrete or the like. It is of advantage in connection therewith if the outer or tread surface edges of the outer sole which extend I essentially parallel to the sole longitudinal axis, are formed - by extensions which project with respect to the lateral surfaces o~ the outer sole.
The lateral extensions o~ the outer sole according to the present invention which form the tread surface edges, lead to an increase of the lateral contours of the outer sole, which is preferably shell-shaped in cross section. As a result thereof, one obtains a considerably increased tread surface in co~parison to the prior art pro~iled outer soles and therewith 4L7:~L
an impro~ed slippin~ st~bility, which is of importance especially for txead soles of such sport shoes, which are used in hall-types of sports or in types of sports in other sport facilities and places with a comparatively hard and frequently also smooth ground.
The lateral extensions forming the tread surface edges extend with advantage beyond the sole longitudinal sides with the exception of the strongly rounded-off forward and rear outex sole ends. It is assured therewith that the aforedescrib-ed advantages of the outer sole according to the present inven-tion become fully effective without the fact that the technical -~
measures necessary therefor lead to an impairment with the ~ ;
intended use of a shoe, especially of a sport shoe, having an outer sole according to the present invention.
In copendin~ application No. 254,362 there is claimed a profiled outer sole for shoes made of a material having rubber-elastic properties, and provided with profiled projections means arranged along lateral sole edges, characterized in that the profiled projection means laterally delimit a tread surface 20 of the outer sole, each of the profiled projection means are provided with at least two V-shaped or zig-zag shaped slots extending obliquely to a tan~ential plane at outer boundary sur-faces of the individual profiled projection means in a bisecting plane thereof, said at least two V-shaped or zig-zag shaped slots are nested one within the other.
The present invention relates to a shoe, especially to a sport shoe, with a profiled outer sole constructed as molded body and made of rubber or of another material with rubber-elastic properties, especially of synthetic resinous ma~erial, having block-shaped or post-shaped profiled projections 1, 1 or raised portions arranged along the lateral sole edges. Such a shoe, especially a sport shoe should excel in that in addition ~l~804~1 ~
to the afore~en~ioned pro~erties, namely a high non-slipping characteristic and stability during the walking, running or jumping movements of its wearer, it possesses an agreeably soft, spring-elastic step and in that therebeyond an intensive inner venting is achieved therebeyond with such shoe. It is thereby of advantage if the block- or post-shaped profiled projections laterally delimiting the outer or tread surface of the outer sole are provided with groove-shaped .

-3a-slots extending at an inclination to the respective tan~ential plane t~ngential at the outer boundary surfaces of the individual profiled projections in thc bisecting plane thereof, if the outer sole is provided within the area of thc forward sole and possibly also of the rear sole with (inner) pro~iled projections surrounded by the block- or post-shaped profiled projections and having hollow spaces open in the direction toward the inner sole, if in the unloaded condition of the outer sole the inner profiled projections project with respect to the tread surface formed by the edge profiling and if the inner sole covering the hollow spaces of the profiled projections is air-permeable.
The edge proEiling surrounding the inner profiled projections which, on the one hand, is form-stable and, on the other, is nonetheless yielding or elastic to a sufficient extent, assures the necessary frictional connection by means of the tread surface antl therewith assures the necessary non-slipping characteristics and standing ability both in case of longitudinal as also cross loads of the shoe according to the present invention, especially of the sport shoe. The inner profiled projections provided with hollow spaces open toward the inner sole condition the springy step~ which by reason of their projection in relation to the outer or tread surface formed by the edge profiling, produce an intensive pumping action by the alternate reduction and increase of the hollow spaces coupled therewith, which pcrmits the inflow into and outflow of the air from the shoe and therewith leads to an intensivc internal ventilation of the shoe.
In that connection, it is particularly advantagcous if the apcrtures or openings of the insole and of the cover sole havc a considcral)ly smallcr cross section than thc hollow spaccs of the profilcd projcctions. A type o~
throttle erfect results from the comparatively smaller cro~ss section of the apertures o~ the insole an~ of the cover sole, which ~ssures the spring elastic step and at the same time assures a suf~icient ventilation oî the interior oî the shoe. .

Referring now to the drawing wherein like re~erence numerals are : .
used throughout the various views to designate li~cc parts, and more particularly ,-to Figures 1 and 2, the sole body made in one piece and preferably constructed shell-shaped consists of a material with rubber-elastic properties such as natural or synthetic rubber, synthetic resinous material made rubber-elastic by the addition of suitable hardeners, preferably on the basis of polyurethane, epoxy resins or the like. The sole body includes at its two lateral edges block-shaped or post-shaped profiled projections or raised portions 2 laterally delimiting the outer or tread surface of the outer sole 1, which are arranged one behind the other in the direction of the sole longitudinal axis 3 and thus form block rows 4 and 5. The outer sole 1 is closed off forwardly by a ring-segmentally shaped profiled projection S.
The block or post-shaped profiled projections 2 and the ring-segmentally-shaped profiled projection 6 enclose in the center portion 7 of the forward sole 8, profilcd projections or raised portions 9 of cylindrical or truncated conical shape with a smaller effective tread surface than the surface of the profiled projections 2, 6 surrounding the same.
Toward the rear, the outer sol~ 1 is closed off by an also ring-segmcntally shapcd profile projection 10. Thc block-shapcd or post-shaped profiled projections 2 and the ring-segmentally-shapcd profile~l projcction 10 7~L
surround in the center portion 11 of the rear sole 12, cylindri-cal or conically truncated pro~iled projections 13 with an also smaller effective tread surface than the surface o~ the profil~d projections 2, 10 surrounding the sameO
The block- or post-shaped profiled projections 2 have an approximately trapezoidally shaped configuration in plan view and more particularly in such a manner that the longer of the two mutually parallel sides forms the edge of the sole tread surface~ :
Three mutually parallel groove-shaped slots 15, 16 and 17 are provided symmetrically to the bisecting planes 14 ;
of the block- or post-shaped profiled projections 2 extending perpendicularly to the sole longitudinal axis 3, which are con-structed roof-shaped and V-shaped and with flanks 15a, 15b, 16a, 16b and 17a, 17b opening toward the sole longitudinal axis 3. The groove-shaped slots 15, 16 and 17 are preferably arranged nested one within the other. The flanks of the groove-shaped slots 15, 16 and 17 subtend with respect to the respective tangential plane 18 tangential the outer boundary surfaces of the individual profiled projections 2 in the bi-secting plane 14 thereof, an angle a of about 20 to about 40s 1 :~
preferably of about 30~. The groove-shaped slots 15, 16 and 17 have preferably a width B of about 1 to about 2 mm. and a depth T (Figure 2), which corresponds approximately to half .
the height H of the block or post-shaped profiled projections 2.
The mutual spacing D of the groove-shaped slots 15, 16 and 17 corresponds advantageously approximately to the width B of such a slot 15, 16 and 17. ~1 For purposes of further improving the non-slip ¦ :
characteristics under loads in the sole longitudinal direction, the ring~se~mentally~shaped 1:~
profiled projections G and 10 are provided with groove-shaped slot:s 19 and 20 extending at least approximately perpendiculaIly~o the sole longitudinal axis 3.
Profiled projections 21 are provide~d with advantage between the blnck-shaped or post-shaped profiled projections 2 separated from one another by more or less large intermediate spaces, which profilcd proiections 21 have a s~nooth surface. The profile depth of these profiled projections 21 correspon~s approximately to that of the profiled projections 2. ~Iowever, the dimensions of the profiled projections 21, especially the width thereo, are smaller, and within the area of the forward sole 8 are even considerably smaller than those of the profiled projections 2.
However, more or fewer than three groove-shaped slots may also be provided in each block or pSt-shaped projection 2 without departing from the scope of the inventive concept. In lieu of a roof or V-shaped profiling, also a zig-zag shaped profiling may be provided, especially with larger profile widths. The profiled proJections 13 in ~he center portion 11 of the rear sole 12 may possibly be profiled in a different manner than Lhe profiled projections 9 in the center portion 7 of the forward sole 8 The obliquely extending groove-shaped slots 15, 16 and 17 in the pro~iled projections 2 lead to an increased elastic deormability of the block- or post-shaped profiled projections 2. One obtains therewith an excellent standing and slipping stability of the outer sole according to the present invention both under loads in the sole longitudinal direction as also in the so]e transverse direction with a compar~tively coarse distribution of the sole edges WhiCIl iS desirable ~vith a vicw toward thc mold costs Th~
7~
proriled projections 8 ;3nd 13 o~ cylindrical or conically truncated shape in the center portion 7 of the forward solc 8 and possibly also in the center portion 11 of the rear sole 12 additionally assist this effect by their construction and configuration and by their arrangement essentially symmetrical to the longitudinal axis 3 o the sole, The outer sole may be constructed, as illustrai:ed and described, as :
shell sole with a laterally circumferential shell edge. However, the present invention can be applied with equal advantage also to flat soles without circumferential shell edge As illustrated in Fig~res 3 to 5~ the outer sole 31 according to the present invention may also be so constructed that the edge profiling 32 is formed by block-shaped or post-shaped profiled projections 34 separated by groove-shaped recesses or slots 33 or is forrned by profiled projections 37 preerably connected with each other band-shaped at the outer sole edges 35 :~
and 36. For purposes of increasing the tread surface, the profiled -~
projections 34 and 37 are enlarged at the outer sole edge 35 and 36 by extensions 39 and 40 ~Figures 3 and 4) extending essentially parallel to the sole longitudinal axis 38, whereby the tread surface edges 41 and 42 formed by the lateral extensions 39 and 40 project by a predetermined amount y with respect to the outer sole edges 35 and 36, properly speakingJ or with respect to the lateral surfaces 43 and 44 of the outer sole 31.
The lateral extensions 39 and 40 at the lateral surfaces 43 and 44 of the outcr sole 31 are constructed as rounded-off shoulders 45 and 46 which extend from the plane of the outer or tread surface 47 formc(l by the proîiled projections 34 and 37 bead-shaped in the upward direction toward the lateral ~i80~7~L
sur~aces 43 and 44 o~ the outer sole 31. The p~ojectin~ len~th y formed by th~ lateral extensions 39 and 40 may amo~nt to about 2 to about 5 mm.
depending on the sole size and intended use of the oute~ 601e 31. ~s a result thereof, one obtains a greater or lesser enlargement of the width Or the outer or tread surface 47, which becomes fav.orable as regards the standin~ ability of the wearer of such a shoe, especially oE a sport shoe.
The lateral extensions 39 and 40 forming the outer tread sur~ace edges 41 and 42 extend advanta~eously beyond the longil;udinal sides of the sole or the -tread sole edges 35 and 36 with the exception of the strongly rounded-off ~orward O aIld rearward outer sole ends 48 and 49 which are provided preferably as U-shaped or circular segmentally shaped profiled projections with groove-shaped slots 50, and 51 extending at least approximately perpendicularly to the sole longitudinal axis.
The inner surface of the outer sole 31 may, as known as such, be 5 constructed wedge-shaped in longitudinal cross section, whereb~t the wedge 52 -(Figure 5~ at first extends flat in the first portion of the rear sole 53 as viewedfrom the sole end and then later on tapers continuously in the direction toward the forward sole 54. With such a wedge sole, the shoulders 45 and 46 forming the lateral extensions 39 and 40 are extended up preferably only within the area of O the forward sole 54 approximately up to the inner surface 55 of the outer sole 31.
In case a particularly high lateral stability and a high non-slipping . characteristic is desirable when the athlete or wearer of the shoe steps or treads on the edge of the shoe, it is of advantage if the shoulders 45 and 46 forming the lateral extensions 39 and 40 are drawn up 'It least within the area of !5 the llat forward sole 54 over the inner surface 55 of the outer sole 31 ~nd 7~L
esp~cially a~3dition~11y engag~ a part o~ the ~lrawn-up shell ed~s~ 5~, in case the outer sole 31 is constructed as known and frequently used shell sole. ~ corrcsponding construction o~ the present invention is illustrated in ~igure 6.
The lateral extensions 39 and 40 o~ the outer sole 31 may be constructed as continuous shoulder band as this is schematically indicated .-in Figure 3 in dash line. The aforementioned lateral stability, however, is still further increased if the lateral extensions 39 and 40 of the outer sole 31 are constructed as shoulder pieces 58 (Figure 5) interrupted by gaps 57. .
For a ~urther improvement of the non-slipping characteristic of the outer sole 31 according to the present invention, it is o~ advantage if the block-shaped or post-shaped profiled projections 34 or the profiled projections 37 connected with each other band-shaped at their outer edge are provided with groove-shaped slots 59 extending obliquely- to the sole longitudinal axis 38.
S If therebeyond also a marked spring-elastic step is desired, it is of advantage if the lateral edge profiling 32 surrounds inner profiled projections 60 constructed as round or strip profiles and having hollow spaces 61 open in the direction toward the inner sole. These inner profiled projections 60 possess elastically yielding side walls and project slightly with respect to the outer or tread surface 47 0 formed by the edge profiling 32, as a result of which the spring-elastic step is assured.
The outer sole according to the present invention possesses In particular with its use for hall types of sports excellent properties, namely a high non-slippin~
characteristic, and a high lateral stability when landing on the sole edges or in 5 case of other strong sole cross loads. The cushion e~ect o~ the outer sole accordir~g -11- .
7~
t~> the l~resent invention which e~;ists by reason of the spring-elastic i.nner profiled projections 60 is aiso very de~irable, e.specially in hall types o~ sports with frequent jump throws as in hand ball or basketb~ll.
Accor(ling to a ~urther development of the present invention, the outer sole, as illustrated in plan view in Figure 1, may also be so constructed that the inner pro~iled projections 73 surrounded by the edge pro~iling 72 in the center portion of the ~orward sole (Figures 7 and 8) and possibly also the .. . . . ................... . .... ..
inner projections 74 and 75 in the center portion of the rear ~ole are constructed as knub~shaped round or elongated profiles, The inner profiled projections 73, 74 0 and 75 are provided with hollow spaces 77 open in the direction toward the inner sole 76. The inner profile projections 73, 74 and 75 project in the unloaded condition of the outer sole 71 by the distance a witll respect to the outer or tread surface 78 formed by the edge profiling 72. The projecting length a of the inner profiled projections 73, 74 and 75 with respect to the tread surEace 78 of .5 the edge profiling 72 corresponds with advantage approximately to the profile wall thickness x provided in the outer or tread surface of the inner profiled projections 73, 74 and 75.
By reason of the projection a of the inner profiled projections 73, 74 and 75, the latter are compressed and subsequently again expant3ed during walking, !0 running or jurnping with the sport shoe according to the present invention, corresponding to the loading and unloading of the outer sole by elastic deformation.
As a result of the alternate decrease and increase o~ the hollow spaces 77 formed by the inner profiled projections 73, 74 and ~5, a pumping action results which permits the air to flow in and out of the shoe and which ef~ects an ef~ective, ~5 intensive internal ventilation o~ the shoe.
This pumpinE~ ~ction can he ~urther enh~nced in that the inner pro~iled projectiol~s 73, 74 and 75 are provided with side walls 79 movable in the manner of a bellows, as illustrated in Figure ~. With a relatively so~t sole .
material, it may additionally be o advantage i only the. outer surîace 80 of the lateral walls 79 o the inner profiled projections 73, 74 and 75 are provided with a bellows profile whereas the inner surraces 81 oï the side walls 79 extend smoothly. The profiled projections.73, 74 and 75.may, liowever, also :
include in principle a bollow profile without outer and/or inner bellows folds;
As shown in Figures 7 and ~, the inner sole 76 of the sport shoe consists D of several layers, namely, o a compensating sole 82, of an welt 83 and o~
a cover sole 84. The compensating sole 82 consists of a porous material compressible in its volume such as rubber or synthetic resinous.foamed material, sponge rubber, rubber hair or the like. The air-permeable cornpen-sating sole 82 rests l;herefore directly on l:he outer sole 71 and covers the center portions of the front and rear sole provided with the inner profiled projections 73, 74 and 75 and additionally with the hollow spaces 77. The welt 83 provided with apertures S5 follows the compensating sole 82. The apertures 85 are at least in part aligned with the hollow spaces 77 of t~e innerprofiled projections 73, 74 and 75. However, it is recommended to provide O more apertures 85 than proEiled projections 73, 74 and 75 or hollow spaces 77.
The cover sole 84 covering the welt 83 may also be provided with apertures.
However, the cover sole 84 may also be Tnade of air-permeable Tnaterial such -~~as sponge rubber with n fabric closing of toward the foot inside. ~ part of the.llpper S7 of leather is illustrated between the inner sole 76 and the shell-:5 shaped edge 86 of the outer sole 71, whose wrapping ~8 is attached to or adhesively fastened at the freely e~;posed inner edge U9 of the outer sole 71.
, ~Ci8~
'rl~e apertures 85 in the inner sole ~6 have a consideral)ly smaller cross section than the hollow sp~ces 77 o~ the proriled projections 73, 74 and 75. ~ type of throttle action rcsults therefrorn which assures the spring-elastic step o the sport shoe with tbe outer sole according to the present invention and at the same time guarantees a suf~icient ventilation o~ the shoe inside.
As shown in ~igure 9, the inner profiled projections may be constructed at least in part also as rounded~off strip profiles. The strip pro~iles 75 may .
... ... .
extend over the entire center portion o~ the ~ront sole and/or over the entire :-center portion oE the rear sole. However, also combinations of strip profiles ~~
D 75 with round profiles 74 are possible as can be seen-~rom Figure 9. 0~ course, also other geometric Eorms of the inner profiled projections 73, 74 and 75 and the combinations thereof are possible with each other.
The edge proEiling 72 may, as described in conjunction with the embodiment according to Figure 1, be provided with groove-shaped slots 90, 5 91 and 92 which extend obliquely to the sole longitudinal axis, as shown in Figure 9.
As shown by the embodiment described hereinabove, a strong de~ormation of the èlastic inner profiled projections 73, 74 and 75 takes place by the walking or running movement. A pumping action results therefrom which ~0 brings about an air circulation in the direction of the doublc arrows P (Figures 7 and 3~. The inner pro~iled projections 73, 74 and 75 which project by a certain distance beyond the outer or tread surface 78 o~ the edge pro~iling 7~, thereby serve as pump elements. The pro~iled projections 73, 74 and 75 assure there-beyond also a spring-elastic step o~ the athlete or wearer o~ the shoe which is 5 very desirable especiaIly with hard floors such as with noors o} halls.

Tlle inner ventil~tion of the shoe, cspecially of the s~orL ~iho~, can be îurther enhanced in ~h;lt air inlet openings are provided in th~ lowcr portion of the ul)per Or the shoe or sport shoe which are in communication with the hollow spaces of the inner proriled projections. In order to prevent the penetration of water and/or of dirt, the air inlet openin~s in the lower part of the upper may be covered off with a cover strip provided with apertures open in the upward direction.
~he outer sole accordmg to the present inverition may, as illustrateà - -and described, be constructed as shell sole with a lateral circumferential O shell edge. However, the present invention can be applied with equal advantage also to flat soles without circumferential shell edge. The outer sole according to the present invention represents a universal sole with numerous possibilities of use. It is suited for all types of sports as also or types of sports on the outside, and more particularly for cin~er tracks as also for plastic tracks 5 or places.
While we have shown and described several embodiments in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as ~nown to those sliilled in the art and we therefore do not wish to be limited to the details shown O and described herein but intend to cover all such changes and modifications as are encompassed by the scope of the appended claims.

The present invention relates to a profiled outer sole made in a ~old ~or shoes, especially for sport shoes, of rubber or of another material with rubber-elastic properties, especially of synthetic resinous material, with block-shaped or post-shaped pro~iled projections arranged along the lateral sole edges.
- This application is a divisional application of copending application No. 254,362 filed ~une ~, 1976.
It is known in connection with ski-, mountain- or hiking boots to provide the lateral sole edges of the outer sole with block- or post-shaped profiled projections arranged in one or several rows. The distance between the individual ;
profiled projections is thereby approximately as large as the width thereof.
This prior art outer sole offers a sufficient gripping ability and non-slip stability in case of a relatively soft :. .
underground. However, it is not possible with these outer soles having post- or block-profile rows, to make the blocks so small .. .
or the rows of blocks so fine in structure that the slipping safety is assured to a sufficient extent not only with a rela-tively soft underground but also with a relatively harder underground.
; The present invention is concerned with the task to so construct an outer sole of the aforementioned type that this outer sole exhibits excellent non-slipping and standing characteristics for the user.
The underlying problems are solved according to the present invention in that the block-shaped or post-shaped profiled projections laterally delimiting the tread surface of the outer sole are provided with groove-shaped slots extending obliquely to the respective tangential plane tangential to the outer boundary surfaces of the individual profiled projections ' ' I
L7~L
in -the bisecting plane thereof.
The deformability and the number of gripping edges o~ the block- or post-shaped pro~iled projections is increased by the groove-shaped slots. The block- or post-shaped proflled projections or raised portions are therewith also able to adapt themselves readily to small unevennesses of the ground and to produce the desired frictional connection.
It is o~ advanta~e i each of the block- or post-shaped pro~iled projections includes two or more mutually ;
parallel groove-shaped slots and if possible the groove-shaped slots are constructed V-shpaed or roof-shaped with the flanks thereof being open in the direction toward the sole longitudinal ;~
axis. The gripping and slipping safety of the outer sole according to the present invention is still further improved in case of longitudinal and cross loads by the inclined position or roof-shaped construction of several groove-shaped slots.
The outer sole according to the present invention may be constructed with advantage in such a manner that it possesses, in addition to a high non-slipping characteristic, an excellent -', 20 standing ability also with a hard and/or smooth underground such as with hall floors of wood, synthetic plastic material, asphalt, concrete or the like. It is of advantage in connection therewith if the outer or tread surface edges of the outer sole which extend I essentially parallel to the sole longitudinal axis, are formed - by extensions which project with respect to the lateral surfaces o~ the outer sole.
The lateral extensions o~ the outer sole according to the present invention which form the tread surface edges, lead to an increase of the lateral contours of the outer sole, which is preferably shell-shaped in cross section. As a result thereof, one obtains a considerably increased tread surface in co~parison to the prior art pro~iled outer soles and therewith 4L7:~L
an impro~ed slippin~ st~bility, which is of importance especially for txead soles of such sport shoes, which are used in hall-types of sports or in types of sports in other sport facilities and places with a comparatively hard and frequently also smooth ground.
The lateral extensions forming the tread surface edges extend with advantage beyond the sole longitudinal sides with the exception of the strongly rounded-off forward and rear outex sole ends. It is assured therewith that the aforedescrib-ed advantages of the outer sole according to the present inven-tion become fully effective without the fact that the technical -~
measures necessary therefor lead to an impairment with the ~ ;
intended use of a shoe, especially of a sport shoe, having an outer sole according to the present invention.
In copendin~ application No. 254,362 there is claimed a profiled outer sole for shoes made of a material having rubber-elastic properties, and provided with profiled projections means arranged along lateral sole edges, characterized in that the profiled projection means laterally delimit a tread surface 20 of the outer sole, each of the profiled projection means are provided with at least two V-shaped or zig-zag shaped slots extending obliquely to a tan~ential plane at outer boundary sur-faces of the individual profiled projection means in a bisecting plane thereof, said at least two V-shaped or zig-zag shaped slots are nested one within the other.
The present invention relates to a shoe, especially to a sport shoe, with a profiled outer sole constructed as molded body and made of rubber or of another material with rubber-elastic properties, especially of synthetic resinous ma~erial, having block-shaped or post-shaped profiled projections 1, 1 or raised portions arranged along the lateral sole edges. Such a shoe, especially a sport shoe should excel in that in addition ~l~804~1 ~
to the afore~en~ioned pro~erties, namely a high non-slipping characteristic and stability during the walking, running or jumping movements of its wearer, it possesses an agreeably soft, spring-elastic step and in that therebeyond an intensive inner venting is achieved therebeyond with such shoe. It is thereby of advantage if the block- or post-shaped profiled projections laterally delimiting the outer or tread surface of the outer sole are provided with groove-shaped .

-3a-slots extending at an inclination to the respective tan~ential plane t~ngential at the outer boundary surfaces of the individual profiled projections in thc bisecting plane thereof, if the outer sole is provided within the area of thc forward sole and possibly also of the rear sole with (inner) pro~iled projections surrounded by the block- or post-shaped profiled projections and having hollow spaces open in the direction toward the inner sole, if in the unloaded condition of the outer sole the inner profiled projections project with respect to the tread surface formed by the edge profiling and if the inner sole covering the hollow spaces of the profiled projections is air-permeable.
The edge proEiling surrounding the inner profiled projections which, on the one hand, is form-stable and, on the other, is nonetheless yielding or elastic to a sufficient extent, assures the necessary frictional connection by means of the tread surface antl therewith assures the necessary non-slipping characteristics and standing ability both in case of longitudinal as also cross loads of the shoe according to the present invention, especially of the sport shoe. The inner profiled projections provided with hollow spaces open toward the inner sole condition the springy step~ which by reason of their projection in relation to the outer or tread surface formed by the edge profiling, produce an intensive pumping action by the alternate reduction and increase of the hollow spaces coupled therewith, which pcrmits the inflow into and outflow of the air from the shoe and therewith leads to an intensivc internal ventilation of the shoe.
In that connection, it is particularly advantagcous if the apcrtures or openings of the insole and of the cover sole havc a considcral)ly smallcr cross section than thc hollow spaccs of the profilcd projcctions. A type o~
throttle erfect results from the comparatively smaller cro~ss section of the apertures o~ the insole an~ of the cover sole, which ~ssures the spring elastic step and at the same time assures a suf~icient ventilation oî the interior oî the shoe. .

Referring now to the drawing wherein like re~erence numerals are : .
used throughout the various views to designate li~cc parts, and more particularly ,-to Figures 1 and 2, the sole body made in one piece and preferably constructed shell-shaped consists of a material with rubber-elastic properties such as natural or synthetic rubber, synthetic resinous material made rubber-elastic by the addition of suitable hardeners, preferably on the basis of polyurethane, epoxy resins or the like. The sole body includes at its two lateral edges block-shaped or post-shaped profiled projections or raised portions 2 laterally delimiting the outer or tread surface of the outer sole 1, which are arranged one behind the other in the direction of the sole longitudinal axis 3 and thus form block rows 4 and 5. The outer sole 1 is closed off forwardly by a ring-segmentally shaped profiled projection S.
The block or post-shaped profiled projections 2 and the ring-segmentally-shaped profiled projection 6 enclose in the center portion 7 of the forward sole 8, profilcd projections or raised portions 9 of cylindrical or truncated conical shape with a smaller effective tread surface than the surface of the profiled projections 2, 6 surrounding the same.
Toward the rear, the outer sol~ 1 is closed off by an also ring-segmcntally shapcd profile projection 10. Thc block-shapcd or post-shaped profiled projections 2 and the ring-segmentally-shapcd profile~l projcction 10 7~L
surround in the center portion 11 of the rear sole 12, cylindri-cal or conically truncated pro~iled projections 13 with an also smaller effective tread surface than the surface o~ the profil~d projections 2, 10 surrounding the sameO
The block- or post-shaped profiled projections 2 have an approximately trapezoidally shaped configuration in plan view and more particularly in such a manner that the longer of the two mutually parallel sides forms the edge of the sole tread surface~ :
Three mutually parallel groove-shaped slots 15, 16 and 17 are provided symmetrically to the bisecting planes 14 ;
of the block- or post-shaped profiled projections 2 extending perpendicularly to the sole longitudinal axis 3, which are con-structed roof-shaped and V-shaped and with flanks 15a, 15b, 16a, 16b and 17a, 17b opening toward the sole longitudinal axis 3. The groove-shaped slots 15, 16 and 17 are preferably arranged nested one within the other. The flanks of the groove-shaped slots 15, 16 and 17 subtend with respect to the respective tangential plane 18 tangential the outer boundary surfaces of the individual profiled projections 2 in the bi-secting plane 14 thereof, an angle a of about 20 to about 40s 1 :~
preferably of about 30~. The groove-shaped slots 15, 16 and 17 have preferably a width B of about 1 to about 2 mm. and a depth T (Figure 2), which corresponds approximately to half .
the height H of the block or post-shaped profiled projections 2.
The mutual spacing D of the groove-shaped slots 15, 16 and 17 corresponds advantageously approximately to the width B of such a slot 15, 16 and 17. ~1 For purposes of further improving the non-slip ¦ :
characteristics under loads in the sole longitudinal direction, the ring~se~mentally~shaped 1:~
profiled projections G and 10 are provided with groove-shaped slot:s 19 and 20 extending at least approximately perpendiculaIly~o the sole longitudinal axis 3.
Profiled projections 21 are provide~d with advantage between the blnck-shaped or post-shaped profiled projections 2 separated from one another by more or less large intermediate spaces, which profilcd proiections 21 have a s~nooth surface. The profile depth of these profiled projections 21 correspon~s approximately to that of the profiled projections 2. ~Iowever, the dimensions of the profiled projections 21, especially the width thereo, are smaller, and within the area of the forward sole 8 are even considerably smaller than those of the profiled projections 2.
However, more or fewer than three groove-shaped slots may also be provided in each block or pSt-shaped projection 2 without departing from the scope of the inventive concept. In lieu of a roof or V-shaped profiling, also a zig-zag shaped profiling may be provided, especially with larger profile widths. The profiled proJections 13 in ~he center portion 11 of the rear sole 12 may possibly be profiled in a different manner than Lhe profiled projections 9 in the center portion 7 of the forward sole 8 The obliquely extending groove-shaped slots 15, 16 and 17 in the pro~iled projections 2 lead to an increased elastic deormability of the block- or post-shaped profiled projections 2. One obtains therewith an excellent standing and slipping stability of the outer sole according to the present invention both under loads in the sole longitudinal direction as also in the so]e transverse direction with a compar~tively coarse distribution of the sole edges WhiCIl iS desirable ~vith a vicw toward thc mold costs Th~
7~
proriled projections 8 ;3nd 13 o~ cylindrical or conically truncated shape in the center portion 7 of the forward solc 8 and possibly also in the center portion 11 of the rear sole 12 additionally assist this effect by their construction and configuration and by their arrangement essentially symmetrical to the longitudinal axis 3 o the sole, The outer sole may be constructed, as illustrai:ed and described, as :
shell sole with a laterally circumferential shell edge. However, the present invention can be applied with equal advantage also to flat soles without circumferential shell edge As illustrated in Fig~res 3 to 5~ the outer sole 31 according to the present invention may also be so constructed that the edge profiling 32 is formed by block-shaped or post-shaped profiled projections 34 separated by groove-shaped recesses or slots 33 or is forrned by profiled projections 37 preerably connected with each other band-shaped at the outer sole edges 35 :~
and 36. For purposes of increasing the tread surface, the profiled -~
projections 34 and 37 are enlarged at the outer sole edge 35 and 36 by extensions 39 and 40 ~Figures 3 and 4) extending essentially parallel to the sole longitudinal axis 38, whereby the tread surface edges 41 and 42 formed by the lateral extensions 39 and 40 project by a predetermined amount y with respect to the outer sole edges 35 and 36, properly speakingJ or with respect to the lateral surfaces 43 and 44 of the outer sole 31.
The lateral extensions 39 and 40 at the lateral surfaces 43 and 44 of the outcr sole 31 are constructed as rounded-off shoulders 45 and 46 which extend from the plane of the outer or tread surface 47 formc(l by the proîiled projections 34 and 37 bead-shaped in the upward direction toward the lateral ~i80~7~L
sur~aces 43 and 44 o~ the outer sole 31. The p~ojectin~ len~th y formed by th~ lateral extensions 39 and 40 may amo~nt to about 2 to about 5 mm.
depending on the sole size and intended use of the oute~ 601e 31. ~s a result thereof, one obtains a greater or lesser enlargement of the width Or the outer or tread surface 47, which becomes fav.orable as regards the standin~ ability of the wearer of such a shoe, especially oE a sport shoe.
The lateral extensions 39 and 40 forming the outer tread sur~ace edges 41 and 42 extend advanta~eously beyond the longil;udinal sides of the sole or the -tread sole edges 35 and 36 with the exception of the strongly rounded-off ~orward O aIld rearward outer sole ends 48 and 49 which are provided preferably as U-shaped or circular segmentally shaped profiled projections with groove-shaped slots 50, and 51 extending at least approximately perpendicularly to the sole longitudinal axis.
The inner surface of the outer sole 31 may, as known as such, be 5 constructed wedge-shaped in longitudinal cross section, whereb~t the wedge 52 -(Figure 5~ at first extends flat in the first portion of the rear sole 53 as viewedfrom the sole end and then later on tapers continuously in the direction toward the forward sole 54. With such a wedge sole, the shoulders 45 and 46 forming the lateral extensions 39 and 40 are extended up preferably only within the area of O the forward sole 54 approximately up to the inner surface 55 of the outer sole 31.
In case a particularly high lateral stability and a high non-slipping . characteristic is desirable when the athlete or wearer of the shoe steps or treads on the edge of the shoe, it is of advantage if the shoulders 45 and 46 forming the lateral extensions 39 and 40 are drawn up 'It least within the area of !5 the llat forward sole 54 over the inner surface 55 of the outer sole 31 ~nd 7~L
esp~cially a~3dition~11y engag~ a part o~ the ~lrawn-up shell ed~s~ 5~, in case the outer sole 31 is constructed as known and frequently used shell sole. ~ corrcsponding construction o~ the present invention is illustrated in ~igure 6.
The lateral extensions 39 and 40 o~ the outer sole 31 may be constructed as continuous shoulder band as this is schematically indicated .-in Figure 3 in dash line. The aforementioned lateral stability, however, is still further increased if the lateral extensions 39 and 40 of the outer sole 31 are constructed as shoulder pieces 58 (Figure 5) interrupted by gaps 57. .
For a ~urther improvement of the non-slipping characteristic of the outer sole 31 according to the present invention, it is o~ advantage if the block-shaped or post-shaped profiled projections 34 or the profiled projections 37 connected with each other band-shaped at their outer edge are provided with groove-shaped slots 59 extending obliquely- to the sole longitudinal axis 38.
S If therebeyond also a marked spring-elastic step is desired, it is of advantage if the lateral edge profiling 32 surrounds inner profiled projections 60 constructed as round or strip profiles and having hollow spaces 61 open in the direction toward the inner sole. These inner profiled projections 60 possess elastically yielding side walls and project slightly with respect to the outer or tread surface 47 0 formed by the edge profiling 32, as a result of which the spring-elastic step is assured.
The outer sole according to the present invention possesses In particular with its use for hall types of sports excellent properties, namely a high non-slippin~
characteristic, and a high lateral stability when landing on the sole edges or in 5 case of other strong sole cross loads. The cushion e~ect o~ the outer sole accordir~g -11- .
7~
t~> the l~resent invention which e~;ists by reason of the spring-elastic i.nner profiled projections 60 is aiso very de~irable, e.specially in hall types o~ sports with frequent jump throws as in hand ball or basketb~ll.
Accor(ling to a ~urther development of the present invention, the outer sole, as illustrated in plan view in Figure 1, may also be so constructed that the inner pro~iled projections 73 surrounded by the edge pro~iling 72 in the center portion of the ~orward sole (Figures 7 and 8) and possibly also the .. . . . ................... . .... ..
inner projections 74 and 75 in the center portion of the rear ~ole are constructed as knub~shaped round or elongated profiles, The inner profiled projections 73, 74 0 and 75 are provided with hollow spaces 77 open in the direction toward the inner sole 76. The inner profile projections 73, 74 and 75 project in the unloaded condition of the outer sole 71 by the distance a witll respect to the outer or tread surface 78 formed by the edge profiling 72. The projecting length a of the inner profiled projections 73, 74 and 75 with respect to the tread surEace 78 of .5 the edge profiling 72 corresponds with advantage approximately to the profile wall thickness x provided in the outer or tread surface of the inner profiled projections 73, 74 and 75.
By reason of the projection a of the inner profiled projections 73, 74 and 75, the latter are compressed and subsequently again expant3ed during walking, !0 running or jurnping with the sport shoe according to the present invention, corresponding to the loading and unloading of the outer sole by elastic deformation.
As a result of the alternate decrease and increase o~ the hollow spaces 77 formed by the inner profiled projections 73, 74 and ~5, a pumping action results which permits the air to flow in and out of the shoe and which ef~ects an ef~ective, ~5 intensive internal ventilation o~ the shoe.
This pumpinE~ ~ction can he ~urther enh~nced in that the inner pro~iled projectiol~s 73, 74 and 75 are provided with side walls 79 movable in the manner of a bellows, as illustrated in Figure ~. With a relatively so~t sole .
material, it may additionally be o advantage i only the. outer surîace 80 of the lateral walls 79 o the inner profiled projections 73, 74 and 75 are provided with a bellows profile whereas the inner surraces 81 oï the side walls 79 extend smoothly. The profiled projections.73, 74 and 75.may, liowever, also :
include in principle a bollow profile without outer and/or inner bellows folds;
As shown in Figures 7 and ~, the inner sole 76 of the sport shoe consists D of several layers, namely, o a compensating sole 82, of an welt 83 and o~
a cover sole 84. The compensating sole 82 consists of a porous material compressible in its volume such as rubber or synthetic resinous.foamed material, sponge rubber, rubber hair or the like. The air-permeable cornpen-sating sole 82 rests l;herefore directly on l:he outer sole 71 and covers the center portions of the front and rear sole provided with the inner profiled projections 73, 74 and 75 and additionally with the hollow spaces 77. The welt 83 provided with apertures S5 follows the compensating sole 82. The apertures 85 are at least in part aligned with the hollow spaces 77 of t~e innerprofiled projections 73, 74 and 75. However, it is recommended to provide O more apertures 85 than proEiled projections 73, 74 and 75 or hollow spaces 77.
The cover sole 84 covering the welt 83 may also be provided with apertures.
However, the cover sole 84 may also be Tnade of air-permeable Tnaterial such -~~as sponge rubber with n fabric closing of toward the foot inside. ~ part of the.llpper S7 of leather is illustrated between the inner sole 76 and the shell-:5 shaped edge 86 of the outer sole 71, whose wrapping ~8 is attached to or adhesively fastened at the freely e~;posed inner edge U9 of the outer sole 71.
, ~Ci8~
'rl~e apertures 85 in the inner sole ~6 have a consideral)ly smaller cross section than the hollow sp~ces 77 o~ the proriled projections 73, 74 and 75. ~ type of throttle action rcsults therefrorn which assures the spring-elastic step o the sport shoe with tbe outer sole according to the present invention and at the same time guarantees a suf~icient ventilation o~ the shoe inside.
As shown in ~igure 9, the inner profiled projections may be constructed at least in part also as rounded~off strip profiles. The strip pro~iles 75 may .
... ... .
extend over the entire center portion o~ the ~ront sole and/or over the entire :-center portion oE the rear sole. However, also combinations of strip profiles ~~
D 75 with round profiles 74 are possible as can be seen-~rom Figure 9. 0~ course, also other geometric Eorms of the inner profiled projections 73, 74 and 75 and the combinations thereof are possible with each other.
The edge proEiling 72 may, as described in conjunction with the embodiment according to Figure 1, be provided with groove-shaped slots 90, 5 91 and 92 which extend obliquely to the sole longitudinal axis, as shown in Figure 9.
As shown by the embodiment described hereinabove, a strong de~ormation of the èlastic inner profiled projections 73, 74 and 75 takes place by the walking or running movement. A pumping action results therefrom which ~0 brings about an air circulation in the direction of the doublc arrows P (Figures 7 and 3~. The inner pro~iled projections 73, 74 and 75 which project by a certain distance beyond the outer or tread surface 78 o~ the edge pro~iling 7~, thereby serve as pump elements. The pro~iled projections 73, 74 and 75 assure there-beyond also a spring-elastic step o~ the athlete or wearer o~ the shoe which is 5 very desirable especiaIly with hard floors such as with noors o} halls.

Tlle inner ventil~tion of the shoe, cspecially of the s~orL ~iho~, can be îurther enhanced in ~h;lt air inlet openings are provided in th~ lowcr portion of the ul)per Or the shoe or sport shoe which are in communication with the hollow spaces of the inner proriled projections. In order to prevent the penetration of water and/or of dirt, the air inlet openin~s in the lower part of the upper may be covered off with a cover strip provided with apertures open in the upward direction.
~he outer sole accordmg to the present inverition may, as illustrateà - -and described, be constructed as shell sole with a lateral circumferential O shell edge. However, the present invention can be applied with equal advantage also to flat soles without circumferential shell edge. The outer sole according to the present invention represents a universal sole with numerous possibilities of use. It is suited for all types of sports as also or types of sports on the outside, and more particularly for cin~er tracks as also for plastic tracks 5 or places.
While we have shown and described several embodiments in accordance with the present invention, it is understood that the same is not limited thereto but is susceptible of numerous changes and modifications as ~nown to those sliilled in the art and we therefore do not wish to be limited to the details shown O and described herein but intend to cover all such changes and modifications as are encompassed by the scope of the appended claims.
