Description
~19~
The invention relates to a closure for shoes, especially ski boots, containing two straight pull straps intended for connection to parts of the shoe and a rotatable actuating member which has two engaging pieces arranged eccentrically with reference to the axis of rotation of the actuating member.
In a known construction of the type described above (for example German Patent No. 20 46 890) the actuating member is connected to the pull straps by means of a type of Maltese cross drive and by means of hinged pull rods in such a way that when the actuating member is rotated in one direction the pull straps are pulled up and thus the parts of the leg o the boot which are firmly connected to the pul.l straps are pulled together, whereas when the actuating member is rotated in the other direction the pull straps and the parts of the leg of the boot connected thereto are pushed apart and thus the boo-t is opened.
~he object of this invention is to develop a closure of the type described in the introduction so that it is distinguished by a particularly simple construction, by its effective adjustability and by a particularly good fit at various points on a shoe, especially a ski boot.
According to the present invention, then, there is provided a closurei for a boot or the like comprising a pair of oppositely extending pull straps adapted at their outer e~d for connection to a portion of the boot, a housing in which the inner ends of the pull straps are received for sliding movement in the longitudlnal direction of the straps, an actuating member, supported by the housing, rotatable about an axis and haviny two driving membe:rs arranged eccentrically with reference to the axis of rotation of said actuating member, the lnner ends of the pull st.xaps being of reduced width for sliding past one another within the housing on opposite sides of the driving ~.,p 1~` ~
6~4 -la members, each of the reduced width inner ends having formed therein a groove opening towards the other pull strap and of a depth corresponding to the eccentricity of the driving members, wherein eac~ of the grooves engages a respective one of the driving members such that rotation of the actuating member moves the pull straps back and forth to open and close the boot.
In this construction of the closure accordlng to the invention the ends of the pull straps are produced with only half the width and are reciprocally guided adjacent to each other and as a result of the construction and arrangement of the said grooves and the engaging pieces an essentially direc-t reciprocal movement of the pull straps and thus a fast, reliable and very effec-tive opening and closing of the associated shoe is achieved.

extre~ely ~impl0 deslgn of the whole closure and good adaptabillty thereof to appropriate parts of tha shoe, predominantly the leg of the boot, :Further datails of the invention are the subject matter of the subordlnate claims c~nd ~re explained in the fo~owing description of an embodiment illus-trated in the drawings, in which Figure 1 fihows a sectional view through the closure (section along the line I-Iin Figure 2)~
Flgure 2 shows a plan vie~ of the closure;
Flgures 3 and 4 show tHo sectionc~l views along the line III-III in Figure 3, one showing the open position and the other showing the closed position of the closure, The clo~ure lllustrated in the drawings has a housing 1, which is preferably made fro~ a ~uitable ~ynthetic materlal. In this housing 1 two substantially straight pull ~traps 2, 3 ara recelved, the outer free ends 2a and 3a respectively of ~hich are to be flxed approximat~ly on the edges of the parts of the shoe which c~re to ba pulled together, preferably parts of the leg of a boot which i8 not illustrated in detail, especlally a ~ki boot. Near the rear wall 8 of the housing 1 facing the shoe, inside thl3 houslng 1 - lf the closure is vlewed ln plan projection (Figure 2) - a drive element ln the form of a rotary drlve wheel 4 is received in a matching ~pace 5 in the central reglon from which two opposing substantially closed guide channels 6, 7 extend as extenslons of each other to both sldes in asub~tantially straight line out of the housing 1, The cross-section of these two guide channels 6, 7 corresponds approximately to the cross-section of the two pull ~traps 2, 3 which are received ln these guide channels 6, 7 and are recipro-cally and longltudinally ~ovable (cf. double arrows A). The rear wall 8 of the housing ha3 a ellghtly curved shape adapted to the point at whlch it is to be applied to the shoe or the leg of the boot (cf, ~igure 1); following this curve the guide channels 6, 7 which are es6entlally cut into this rear wall 8 and the pull ~traps 2, 3 which are movable therein can be provlded with a corresponding curvature, On tha lower surface there~f facing the ski boot the rotary drlve wheel 4 has two tan~s 22, 23 which project approximately ln the axlal direction, have a circularcross-sectlon and are arranged eccentrically with reference to the central axis of rotatlon DA of this rotary drive wheel 4 and thus of an actuating member of which tha rotary drive wheel forms a part.
. 3 _ 6~
The er~ds of the t~o pull straps 2, 3 which face each other and are located inside the houslng 1 - cf. in partic~Ll.ar Flgures 3 and 4 - only have half the uldth, i.e.
in the lllustrated embodlment these ends of the two pull straps 2, 3 which face each other have approximately rectangular latches 2b or 3b ~hich face each other, the length thereof (in the longitudinal direction of the pull straps) being suchthat these latches al~ays lie inside the guide channels 6, 7 in every positlon of the closure or the pull straps 2, 3. These ends of the pull straps provided withlatches 2b, 3b lie adjacent to each other in such a way that they are guided so as to be longitudinally movable on the one hand on the longitudinal sides of their latches 2b, 3b faclng each other and on the other hand on the corresponding inner ~alls of the relevant guide channels 6, 7 (cf, double arrows A).
Each of lthese ends of the pull straps provided with the latches 2b, 3b also contains a groove 18 or 19 respectively which is open towards the other pull strap 2/3 or the opposite longitudinal edge of the other latch, the said groove in this embodiment being prefera~;Ly cut approximately at right angles into the corresponding longitudinal edge of the latch 2b, 3b, The depth of this groove corresponds to the eccentriclty of the tangs 22, 23 on the rotary drive wheel 4 (cf. Figures 3 and 4), and the ~idth of the groove corresponds approximately to the dlameter o-f the relevant tang 22 or 23, the base of sach groove 18, 19 being semicircular and adapted to the dlameter of the tang 22, 230 The tangs of the rotary drive wheel 4 belongingto the actuatlng member eng~3e ln these grooves 18, 19 so that a form-locking drive coupling is produced.
An opening 9 l~s provlded ln the rear wall 8 of the housing faclng the shoe, Hhllst ln the opposlng upper Nall 10 of the houslng a bore 11 is provided for mounting the rotary drlve wheel 4. This upper houslng~ wall 10 has a substantially flat upper surface 12 wlth a circular ¢roove 13 formed ln it, An equally circular pro~ectlne rim 28 of` a rotary actuatlng knob 26 which is arranged on the upper houslng ~lall 10, also forms a part of the actuating member and - as wlll be described ln greater detail - is connected to the rotary drive wheel 4 so as to be flxed a~ainst rotation engages ln the groove 13, The external diameter of theproJectlng rim 28 which at the same time fonns the external periphery of the rotary actuatlng Icnob 26 is adapted to the external àiameter of the g~roove 13 aubEItantlally without clearance, and this projectlng rim 2~ ls guided so as to b~ rotatable ln the groove 13, Thls groove 13 has ~;tops 14, 15 to limlt rotation Nhich are formed by end surf`aces of an annular section 13a which corresponds toapproximately half the periphery of the groove and has an increased radial width.
A projectlng stop 29 which is fixed on the projecting rim 2~'3 of the rotary actuatinK
knob 26 engag~s.s in the widened annular sectlon 13a of` the groove 13 in such a way g~4 that it eome~ to rest agalnst one of the t~o rotation-limitlng stops 14 or 15 ~hen the rotary aetuating knob 26 has reached one of its t~o rotational end positlgns, namely the completely open position or the eompletely closed posltion. The ler.gth of the annular sections 13a extending in the peripheral direction does not neeessarily have to correspond to half the circumference, but is al~ays adapted to the neeessary size of rotation.
The rotary drive wheel 4, whieh ls rotatably guided eentrally in the housing 1, has a journal pln 24 which projeets outHards and upwards on the upper side of the said ~heel fae.~ga~thf~~angs 22, 23. The journal pin 24 is eonstrueted at least in the region of its free end whieh extends upwards through the elosure housing 1 in the form of an external square 25 and is provided with an axial threaded boremachined into this end. The rotary aetuating knob 26 has a square reeess ln ltseentre which ls adapted to the eross-seetion of the external square 25 and wlth thls lt is pushed onto the external square 25 of the journal pin 24 so that the rotaryactuatlng Icnob 26 and the rotary drive wheel 4 are eonneeted to each other so as to be fixed against rotat~on and form the essential parts of the aetuating member for the elonure, The aetuatlng knob 26 mounted on the journal pin 24 of the rotary drivc wheel ~ is also firmly screwed onto the journal pin 24 and thus to the rotary drive wheel 4 by means of a serew 27.
A~ shown in P`igures 1 and 2, at least two stops 16, 17 of spherleal segment shape pro~ect upwards from the flat surfaee 12 of the upper houslng wall 10, and in the lllustrated embodlment these stops are opposed approximately diametrieally on the surfaee 12, Two approxlmately diametrically opposed flat raised areas 30, 31 are constructed - lntegral wlth the rotary actuating knob 26 - lnside the projectlngrim 28 on the side of the rotary aetuating knob 26 faclng the closure houslng 1,and these raised areas slide along the fla-t surfaee 12 of the upper housing wall 10 when the rotary actuating knob 26 ls rotated (ln the dlrectlon of the double arro~ B), A racess 32, 33 of spherlcal scgment shape corresponding to the pro-jecting stops 16, 17 ls macle in each of the ralsed areas 30, 31, and these recesses 32~ 33 eo-operate the stops 16t 17 in such a way that in each rotational end positlon, both ln the open position and ln the closed position, at least one recess 32 or 33 eng~ge~ ~lth a eorrespc)nding stop 16 or 17 respect.Lvely.
To onable the rotary actuatlng knob 26 to be rotatecl wlthout dlfflcutly in one or the other clirectlon (double ~rrow ~) in order to open and c:lose the closure or the rele~ant shoe (especially a skl boot), thls rotary aotuatln~ knob 26 has on lts upp6r surfaeo faclng away ~rom the front houslng wall 10 a strong ralsed gripping part 34 whlch extsnds cliametrally and has a stepped bore 35 to recelve the screw 27 ~ s -4~
in its centre, As sho~m ln Figure 1, the upper approximately cylindrical end ofthis stepped bore 35 can be illed by a small cylindrlcal stopper or the 11ke 34a above the screw 27 so that the upper surface of the gripping part 34 i8 completely :smookh and closed, The actuation of this shoe closure should be largely comprehensible from the above explanation and the illustration in Flgures 3 and 4, in which Figure 3 shows the -co~pletely - open position and Flgure 4 shows the ~ completely - closed position of the closure. They also show that the tangs 22, 23 are c~Lways in form-locking driving engagement with the relevant groove 18 or 19 in the corresponding end of a pull strap in every closure posltion (both in the open and the closed position and ln every intermediate position). In this embodiment it is also particularly advantageous if the pull strap ends each have a recess 20, 21 in the shape of a circ~Lar segment or syncline (cf. Figure 3) adapted to the diameter of the tangs22, 23 on the opposing longitudinal latch edges of the said pull strap ends, andthase recesqes are made in the reglons pointing away from the free strap end with their centres distanced from the grooves 18, 19 also provided therein for engagement with the tangs, their centre-to-centre distance corresponding to the cen-tre-to-centre distance of the two tangs 22, 23 which are diametrically opposed on the rot~ry drive wheel 4, In the completely closed posit:Lon of the straps 2, 3 or of the closure, a groove 18 or 19 and a recess 20, 21 respectlvely thus lie exactlyopposite one another so that the relevant tang 22 or 23 respectively ls receivedpartlally ln the groove 1~ or 19 respectively and parti~Llyln the opposing recess 20 or 21 respectively, Thus ln the closed position an addltional lock is provlded which prevsnts the closure from being forced open by the straps 2, 3, The ~lo~re descrlbed above can be made from any suita~Le material which is sufficiently stable. As regards stability and manufactllre, however, lt ls gener~Lly preferahLe for the rotary drlve wheel 4 and the tangs 22, 23 mounted thereon to be produced fro~ high-gra~e steel, the pull straps 2, 3 to be made from metal, preferablg sheet steal, and the closure houslng 1 and the rotary actuating knob 26 from a suitable sufficlently stable plastics material. In order to ensure reliable guiding inside the parts made from plastics material in thLs embodiment it i8 aLso c~dvantageous to insert a met~L bush into the stepped bore 35 of the rotary actuatlng knob 26 whil~t an approximately plate-shaped met~l insert 37 with a square hole for the externc~L square 25 is inserted in the lower portion of the rotary~actuating knob which receives the extern~L square 25 of the ~ournal pin 24 (Figure 1) .

Flgure 2 shows a plan vie~ of the closure;
Flgures 3 and 4 show tHo sectionc~l views along the line III-III in Figure 3, one showing the open position and the other showing the closed position of the closure, The clo~ure lllustrated in the drawings has a housing 1, which is preferably made fro~ a ~uitable ~ynthetic materlal. In this housing 1 two substantially straight pull ~traps 2, 3 ara recelved, the outer free ends 2a and 3a respectively of ~hich are to be flxed approximat~ly on the edges of the parts of the shoe which c~re to ba pulled together, preferably parts of the leg of a boot which i8 not illustrated in detail, especlally a ~ki boot. Near the rear wall 8 of the housing 1 facing the shoe, inside thl3 houslng 1 - lf the closure is vlewed ln plan projection (Figure 2) - a drive element ln the form of a rotary drlve wheel 4 is received in a matching ~pace 5 in the central reglon from which two opposing substantially closed guide channels 6, 7 extend as extenslons of each other to both sldes in asub~tantially straight line out of the housing 1, The cross-section of these two guide channels 6, 7 corresponds approximately to the cross-section of the two pull ~traps 2, 3 which are received ln these guide channels 6, 7 and are recipro-cally and longltudinally ~ovable (cf. double arrows A). The rear wall 8 of the housing ha3 a ellghtly curved shape adapted to the point at whlch it is to be applied to the shoe or the leg of the boot (cf, ~igure 1); following this curve the guide channels 6, 7 which are es6entlally cut into this rear wall 8 and the pull ~traps 2, 3 which are movable therein can be provlded with a corresponding curvature, On tha lower surface there~f facing the ski boot the rotary drlve wheel 4 has two tan~s 22, 23 which project approximately ln the axlal direction, have a circularcross-sectlon and are arranged eccentrically with reference to the central axis of rotatlon DA of this rotary drive wheel 4 and thus of an actuating member of which tha rotary drive wheel forms a part.

These ends of the pull straps provided withlatches 2b, 3b lie adjacent to each other in such a way that they are guided so as to be longitudinally movable on the one hand on the longitudinal sides of their latches 2b, 3b faclng each other and on the other hand on the corresponding inner ~alls of the relevant guide channels 6, 7 (cf, double arrows A).
Each of lthese ends of the pull straps provided with the latches 2b, 3b also contains a groove 18 or 19 respectively which is open towards the other pull strap 2/3 or the opposite longitudinal edge of the other latch, the said groove in this embodiment being prefera~;Ly cut approximately at right angles into the corresponding longitudinal edge of the latch 2b, 3b, The depth of this groove corresponds to the eccentriclty of the tangs 22, 23 on the rotary drive wheel 4 (cf. Figures 3 and 4), and the ~idth of the groove corresponds approximately to the dlameter o-f the relevant tang 22 or 23, the base of sach groove 18, 19 being semicircular and adapted to the dlameter of the tang 22, 230 The tangs of the rotary drive wheel 4 belongingto the actuatlng member eng~3e ln these grooves 18, 19 so that a form-locking drive coupling is produced.
An opening 9 l~s provlded ln the rear wall 8 of the housing faclng the shoe, Hhllst ln the opposlng upper Nall 10 of the houslng a bore 11 is provided for mounting the rotary drlve wheel 4. This upper houslng~ wall 10 has a substantially flat upper surface 12 wlth a circular ¢roove 13 formed ln it, An equally circular pro~ectlne rim 28 of` a rotary actuatlng knob 26 which is arranged on the upper houslng ~lall 10, also forms a part of the actuating member and - as wlll be described ln greater detail - is connected to the rotary drive wheel 4 so as to be flxed a~ainst rotation engages ln the groove 13, The external diameter of theproJectlng rim 28 which at the same time fonns the external periphery of the rotary actuatlng Icnob 26 is adapted to the external àiameter of the g~roove 13 aubEItantlally without clearance, and this projectlng rim 2~ ls guided so as to b~ rotatable ln the groove 13, Thls groove 13 has ~;tops 14, 15 to limlt rotation Nhich are formed by end surf`aces of an annular section 13a which corresponds toapproximately half the periphery of the groove and has an increased radial width.

They also show that the tangs 22, 23 are c~Lways in form-locking driving engagement with the relevant groove 18 or 19 in the corresponding end of a pull strap in every closure posltion (both in the open and the closed position and ln every intermediate position). In this embodiment it is also particularly advantageous if the pull strap ends each have a recess 20, 21 in the shape of a circ~Lar segment or syncline (cf. Figure 3) adapted to the diameter of the tangs22, 23 on the opposing longitudinal latch edges of the said pull strap ends, andthase recesqes are made in the reglons pointing away from the free strap end with their centres distanced from the grooves 18, 19 also provided therein for engagement with the tangs, their centre-to-centre distance corresponding to the cen-tre-to-centre distance of the two tangs 22, 23 which are diametrically opposed on the rot~ry drive wheel 4, In the completely closed posit:Lon of the straps 2, 3 or of the closure, a groove 18 or 19 and a recess 20, 21 respectlvely thus lie exactlyopposite one another so that the relevant tang 22 or 23 respectively ls receivedpartlally ln the groove 1~ or 19 respectively and parti~Llyln the opposing recess 20 or 21 respectively, Thus ln the closed position an addltional lock is provlded which prevsnts the closure from being forced open by the straps 2, 3, The ~lo~re descrlbed above can be made from any suita~Le material which is sufficiently stable. As regards stability and manufactllre, however, lt ls gener~Lly preferahLe for the rotary drlve wheel 4 and the tangs 22, 23 mounted thereon to be produced fro~ high-gra~e steel, the pull straps 2, 3 to be made from metal, preferablg sheet steal, and the closure houslng 1 and the rotary actuating knob 26 from a suitable sufficlently stable plastics material. In order to ensure reliable guiding inside the parts made from plastics material in thLs embodiment it i8 aLso c~dvantageous to insert a met~L bush into the stepped bore 35 of the rotary actuatlng knob 26 whil~t an approximately plate-shaped met~l insert 37 with a square hole for the externc~L square 25 is inserted in the lower portion of the rotary~actuating knob which receives the extern~L square 25 of the ~ournal pin 24 (Figure 1) .

an actuating member, supported by said housing, rotatable about an axis and having two driving members arranged eccentrically with reference to the axis of rotation of said actuating member;
the inner ends of said pull straps being of reduced width for sliding past one another within said housing on opposite sides of said driving members, each of said reduced width inner ends having formed therein a groove opening towards the other pull strap and of a depth corresponding to the eccentricity of said driving members, wherein each of said grooves engages a respective one of said driving members such that rotation of said actuating member moves said pull straps back and forth to open and close said boot.
a pair of oppositely extending pull straps adapted at their outer end for connection to a portion of said boot;
a housing in which the inner ends of said pull straps are received for sliding movement in the longitudinal direction of said straps;
an actuating member, supported by said housing, rotatable about an axis and having two driving members arranged eccentrically with reference to the axis of rotation of said actuating member;
the inner ends of said pull straps being of reduced width for sliding past one another within said housing on opposite sides of said driving members, each of said reduced width inner ends having formed therein a groove opening towards the other pull strap and of a depth corresponding to the eccentricity of said driving members, wherein each of said grooves engages a respective one of said driving members such that rotation of said actuating member moves said pull straps back and forth to open and close said boot.
2. The closure of Claim 1 wherein said housing includes a channel for guiding the sliding movements of each of said pull straps, the width of said channel corresponding substantially to the full width of each of said straps, a portion of each of the straps being at all times in said channel.
3. The closure of Claim 1 wherein each of said driving members extends axially from one side of a rotary drive wheel, forming part of said actuating member, towards said pull straps.
4. The closure of Claim 3 including a journal pin extending axially upwardly from said rotary drive wheel and through a surface of said housing.
5. The closure of Claim 4 wherein said actuating member further includes a rotary actuating knob arranged on said housing and having a recess formed therein in which the outer end of said journal pin is received to connect said knob with said rotary drive wheel, said knob and said journal pin being connected to prevent relative rotation therebetween.
6. The closure of Claim 5 wherein said recess and the outer end of said journal pin are square in cross sectional shape.
7. The closure of Claim 5 wherein said housing has a substantially flat surface wall facing the rotary actuating knob, said wall having a circular groove formed therein, said rotary actuating knob having a circular projecting rim received in said groove, said rim having an external diameter corresponding substantially to the external diameter of said groove.
8. The closure of Claim 7 wherein said surface wall has stops and wherein said knob has a projection for engaging said stops to limit rotation of said knob.
9. The closure of Claim 8 wherein said wall includes at least two stops of spherical segment shape projecting upwardly therefrom, and wherein said knob has, at least two recesses of spherical segment shape confronting said surface for receiving said stops therein.
10. The closure of Claims 1, 2 or 9 wherein each of said pull straps includes a recess for engaging the respective one of said driving members received within the groove of the other of said pull straps when said actuating member is rotated to fully close said boot, whereby the centre-to-centre distance between said recesses corresponds to the centre-to-centre distance between the two driving members.
11. The closure of Claims 1, 2 or 9 wherein said housing is curved in conformity with the curvature of said boot, said pull straps having a corresponding curvature.
