Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a multifunctional actuating device that can be used in particular in ski boots.

PRIOR ART AND ITS PROBLEMS The use of devices in ski boots that allow the closing of the waistband of ski boots, the tightening of pressure bodies in the area of the instep or heel, or other normally required functions. is widely known.

If it is desired to carry out two or more of the said functions simultaneously, the known boots have separate actuation means for each required function, but for this purpose it is possible to arrange various devices on the boot. There are significant problems with this.

As a solution to this shortcoming, the applicant has proposed US patent application Ser.
However, even the one in this application is not sufficiently completed.

This conventional device includes a storage body that can be attached to a ski boot and supports a lever, which can be operated from the outside and has a center rotatably supported by the storage body. The shaft is operatively coupled to the shaft with an intervening ratchet assembly.

The actuating device further includes a selection device, which can be operated from outside the enclosure and which is
and a second cable, etc., and is selectively engageable with the first and at least second take-up repulleys for the cable and the like.

Although the solution described above is clearly effective, it has the following drawbacks. That is, first the user has to select the desired function by means of the selection device, and then, when the central shaft is turned, the first and second pulleys each wind the cable an equal length. The point is that

If each cable has to be adjusted differently, the lever may have to be operated several times to obtain the desired degree of adjustment for each function.

The aim of the invention is to provide a device which allows all the necessary functions to be concentrated in one component and which makes it possible, for example, to wind up the constant pressure body and the cable or band acting on the waistband of ski boots separately. The purpose is to eliminate the above-mentioned drawbacks.

Within this goal, the object of the invention is to provide a mounting that allows each function to be adjusted separately without the need for prior selection.

Another object of the invention is to provide a device that is compact so that it can be placed in the most convenient location on a ski boot, where it is easily accessible for operation.

Yet another object is to provide a device of simple construction.

(Means for Solving the Problems) The goals and objectives of the above-mentioned problems, and other objects which will become apparent below, are that the ski boots are provided with at least one movable member of the boot. A multifunctional actuating device, in particular for ski boots, comprising a housing supporting an actuating assembly for actuating at least two tension members coupled to a actuating at least one actuating shaft kinematically coupled to at least one first winder and one second winder for alternating said actuating assembly to said first winder and said second winder; kinematic switching means are provided for kinematically coupling the first winder and the second winder to the unwinding direction, and further means are provided for releasably stopping rotation of the first winder and the second winder in the unwinding direction. This is accomplished by a device featuring the following characteristics:

EMBODIMENT AND OPERATION In FIGS. 1 and 2 of the accompanying drawings, the multifunctional actuating device 1 comprises a housing 2 carried, for example, in the rear region of the rear waistband of a ski boot.

The actuating assembly 3 is snap-coupled to the housing 2 and consists of a first base 4 and a second base 5, which are essentially columnar;
The first base includes a shaft hole 6.

A pair of spacers 7 are arranged diametrically in the hole 6 and keep the bases 4, 5 parallel to each other, each of the bases having two planes on a plane perpendicular to the plane passing through the spacer.
Pairs of through holes 8, 9 are provided, in each pair both holes having the same axis parallel to that of the axial hole 6.

The first fin 10 and the second fin 11 are the base 4,
5, is insertable into the gap not occupied by said spacer 7, and is arranged radially with respect to the base, and has holes 8, 9 in the fin, perpendicular to its longitudinal solid axis. A matching pivot 1 with a diameter equal to the provided hole 14.15
It is pivotally attached to the same base by 2°13.

Said fin is provided with a pair of tk 116° 17 on opposite sides, the teeth of which are on the faces on which the faces of the fin opposite the iS2 base 5 and the first base 4 lie, respectively.

The teeth project beyond the opposite ends of the fin and are connected to the fin along a section extending approximately 45° to the longitudinal solid axis of the fin.

The above-mentioned 45° portion is located approximately on the plane where the peripheral portion of the shaft hole 6 provided in the first base 4 is located.

In order to keep the fins 10.11 stationary together in a neutral position, i.e. with their longitudinal axes in the diametrical axes of the bases 4, 5, springs 18a, 18b and 19a, 19b are inserted between the fins and the base. It can be interposed between.

An annular seat 20 is provided on the side of the first base 4 for a ring 21 that keeps the base 4 connected to the storage body 2 .

The side surface of the first base 4 includes the actuating assembly 3 and the fin 1 during use.
An annular protrusion 22 is further provided for snap-fitting the ends of the knob 23 covering both 0.11.

A first shaft 26 and a second shaft 27 coaxial therewith.
The first ends 24 and 25 of are positionable in the hole 6.

said two shafts are freely rotatable relative to each other;
The ends 24.25 are substantially cylindrical.

Knurled sides each have teeth 16.1 of fins 10.11
It is facing 7.

A first large gear 28 and a second large gear 29 are provided at ends of the first shaft and the second shaft opposite to the first end, respectively.

The first large gear 28 meshes with a first gear 30 which is freely pivoted on the storage body 2, and the first conical gear 31 is keyed to the pivot of the first gear and is firmly attached to the winder. The second conical gear 32 cooperates with the second conical gear 32 .

The winder is generally cylindrical and rotatably mounted inside the enclosure 2 and located along a longitudinal axis perpendicular to that of the shafts 26,27.

Adjacent to the conical gear 32, the shirt 18 has an annular groove 34
and a transverse sheet 35 for a band, into which the band can be inserted, for example to close the waistbands together.

Beyond the seat 35 in a direction opposite to the groove 34, an annular ridge 36 is provided on the shaft 33 and connects it to the housing 2.
A spring 37 is provided between the base of the housing and the base of the housing, the ends of which are attached to the housing and the raised portion.

On the other hand, a second large gear 29, which is rigidly attached to the second shaft 27, meshes with a second gear 38, which is freely pivoted on the storage body 2, and which is provided with a cable 40t for winding, for example. The pulley 39 is firmly attached.

The means for releasably stopping the rotation of the band and cable in the unwinding direction comprises, for example, a brake 41, which is applied only to the pulley 39 to simplify the drawing.

The brake 41 is a pivot 4 that projects inside the storage body 2.
2, said brake is complementary to the wall of the groove of the pulley and cooperated with said wall by a matching spring 43.

The brake allows winding of the cable 40 and prevents its unwinding. This brake can be released from the outside using a lever (not shown).

The working of this device is as follows. That is, the knob 23
When rotated in the clockwise direction, the teeth 17 interact with the knurled side surface of the end 25 of the second shaft 27, and the inner wall of the knob 23 then rotates against the fin 10 on the side opposite the teeth 16,17. .11 to position the fins io, ti along an axis oblique to the diametrical axis of the bore 6 and to rotate the fins 10.11 about their pivots 12,13.

Further rotation of the knob 23 rotates the shaft 27 and its large gear 29, which allows the second gear 38 to wind the cable 40 onto the pulley 39.

On the other hand, when the knob 23 is rotated counterclockwise, the fin 1
0.11 takes a position that allows the teeth 16 to interact with the knurled surface of the end 24 of the first shaft 26, after which further rotation of the knob causes the gearwheel 28 to rotate, which
The first gear 30 and the conical gears 31, 32 transmit the motion to the shaft 33 of the winder, making it possible to wind the band.

At this time, since the shaft 27 cannot be operated, the boot 9
39 does not work.

A brake 41 prevents the pulley 39 and the shaft 33 from rotating in the opposite direction, that is, in the unwinding direction. Therefore, in order to take off the boots, it is sufficient to operate the brake 41 to free the pulley 39 and shaft 33, thereby allowing them to rotate in the unwinding direction.

FIGS. 3 to 7 show other embodiments of the present invention.
ilo1, which consists of a receptacle 102 which can be attached to, for example, the rear waistband of a ski boot. The housing 102 supports an inner shaft 126 and an outer shaft 127 coaxial with and freely rotatable with respect to the inner shaft 126, each of which has a vertical axis and a drum 133 with a substantially vertical axis. It acts on a pulley 139 having a horizontal axis of rotation (see FIG. 3).

More specifically, a first large gear 128 is provided at the right end of the inner shaft 126 and meshes with a gear 130 which has a groove 134 and a conical gear 132 keyed to a drum 133. Set of interlocking conical teeth 1
31. A second large gear 129 is provided at the right end of the outer shaft 127 adjacent to the first large gear 128 , and this large gear is connected to the first groove 13 of the pulley 139 .
It meshes with a set of teeth 138 provided at an intermediate position between 9a and second groove 139b.

The pulley 139 can, for example, pass a cable (not shown) through the groove 139 which acts on the constant pressure body in a manner known per se.
It can be used to wind up a.

The drum 133, on the other hand, can be used to wind up a band (not shown) adapted to close the waistband and which can be connected to the drum by means of an axial slit 135. A helical spring 137 is further provided on the drum 133 in order to facilitate the initial winding of the band onto the drum when closing the waistband in a manner known per se.

Actuation assembly 103 is advantageously snap-coupled to housing 102 and is located at the left end of coaxial shafts 126,127.

The actuation assembly 103 has a support ring 104 with an outer raised portion 104b that snaps into the housing 102 and allows rotation thereof. The ring 104 further includes an annular seat 120 for a cylindrical helical spring 121 that pushes the ring 104 against its raised portion 104b against the housing 102.

Ring 104 includes columnar sectors 106, sector 1
06 has a ridge 122 for snap-coupling to the knob 123 of the columnar sheet 123a housing said sector to allow at least partial rotation of the knob 123 relative to the ring 104.

The side of the columnar sector 106 opposite the ring 104 has tabs 10 diametrically opposed between the sectors 106.
It is closed by a base 105 with 8.

The tabs 108 are respectively arranged inside trapezoidal sheets 118 provided at positions facing each other in the diametrical direction of the columnar sheet 123a of the knob 123. The tabs 108 each have a hole 109 for a pivot 112, which includes a first pair of fins 110.110ac7) and a second pair of fins 7111°11 housed in the trapezoidal seat 118 of the knob.
1a are pivotally connected.

The fins 110, 110a are diametrically opposed and each include a first gear 124 rigidly attached to the left end of the inner shaft 126.

Similarly, fins 111.1lla are each fin 1
10, 110a and rigidly attached to the outer shaft 127. Each of the 7S2 gears 125 has teeth 117.

Thus, when knob 123 is rotated counterclockwise in FIG.
, so that the teeth 116 mesh with the gear 124 . Further rotation of knob 123 in the same direction activates inner shaft 126 and drum 133. Fin 111
, 1lla south 117 is in a position opposite to 116, so gear 125 has 7 (n 111, 1lfa (7) teeth 1
It does not engage with 17. To engage the gears 125 and rotate the outer shaft 127, the knob 123 may be rotated clockwise in FIG. Similarly, teeth 116 do not engage gear 124 in this case.

In order to maintain the actuating assembly 3 in the neutral position shown in Fig. 7,
That is, 1l16. In order not to engage either of the pairs of i17 with their respective gears, the cylindrical helical spring 1
Elastic means 19 are provided, which springs are applied to diametrically opposed seats 114 in the shape of a donut-shaped sector formed between the opposite surfaces of the knob 123 and the ring 104 in the vicinity of the columnar sector 106. It is accommodated.

Spring 119 acts in opposite directions between abutment 123b of knob 123 and abutment 104b of ring 104.

The drum 133 and pulley 139 are provided with means for stopping rotation in the unwinding direction in order to secure the tension member (band and cable).

In particular, the pulley 139 is located next to the set of teeth 138,
A first brake 154 pivotally mounted eccentrically to the storage body 102
It has a groove 139b that can be engaged with.

The brake 154 shown in FIGS.
having a substantially pentagonal profile complementary to the inner profile of 9b;
Since it is pivotally mounted eccentrically, when the pulley 139 makes one rotation counterclockwise, that is, in the unwinding direction, the brake 1
54 is pushed inside the groove 139b and the friction between the wall of the groove 139b and the outer wall of the brake 154 prevents further rotation of the pulley. Elastic means such as a spring 160 is provided to facilitate engagement between the groove 139b and the brake 154.

The fixing means for the drum 133 consist of a second brake 155 which applies to the groove 134 provided in the gear 130 and prevents the rotation of the gear 130 in a clockwise direction in FIG. Spring 161 acts on the brake in the same way as described above.

The means for stopping the rotation of the pulley 139 and the drum 133 are provided with actuation means for enabling unwinding of the tension member connected thereto.

The actuation means have a first push button 152 which can be actuated from the outside and which has a cam 152a which is pivotally connected to the housing 102 and which acts on a first brake 154; Push the push button 152 downwards (
(FIG. 6) When pressed, cam 152a acts on brake 154 to move it away from groove 139b.

Similarly, the second push button 153 acts on the brake 155 by means of the cam 153a, causing the gear 130 and the drum 133 to
to release.

Restraint means are provided to keep the push buttons 152, 153 in a position to release the brakes 154, 155, respectively. This restraining means includes a front set of teeth 104a provided on the ring 104, as shown in particular in FIG.
It consists of vibrating teeth 150, 151 with hemispherical protrusions 150a, 150b, respectively, which interact with the tabs 152b, 153b of the push buttons 152, 153.

The vibrating teeth 150 , 151 are pivotally mounted on axes 156 , 157 formed in an angular pivot 158 rigidly attached to the housing 102 .

With particular reference to FIG.
so that the tab 152b passes through the hemispherical protrusion 150a of the vibrating tooth 150.

The tab 152b passes through the hemispherical protrusion 150a =
zba=wc8I, 1.ノU-2;IJw-/I+-/
) to return to the normal position by elastic means such as (not shown). The pushbutton 152 remains in the released position because the tab 152 abuts the abutment surface 150b of the protrusion 150a (similarly, the vibration m151 has a hemispherical protrusion 151a with an abutment surface 151b).

At this time, when the knob 123 is rotated, the tooth set 1 in the axial direction
04a rotates the vibrating tooth 150 enough to lower the hemispherical protrusion 150a, so that the tab 152b of the push button 152 passes through it and presses against an elastic means (for clarity sake), such as a spring. (not shown) to return to the fixed position.

The rotation of ring 104a simultaneously acts on vibrating teeth 151 and releases push button 153 in exactly the same way.

This device works as follows. That is, the knob 123
Clockwise rotation acts on the pulley 139 to wind up a cable connected to a constant pressure body, for example, until the desired locking effect is reached, which is maintained by the movement of the brake 154. When the knob 123 is turned counterclockwise, the drum 133 rotates and winds up a band, for example for joining the waistband of a boot, until the desired degree of closure is achieved. , maintained by brake 155.

To take off the boots, the pushbuttons 152, 153 that release the brakes 154, 155 can be operated to allow the waistband to be released and the restraints to be released.

The presence of the locking means has the advantage that the pushbutton does not have to be kept pressed and is therefore easy to operate.

When putting on the boots again, in order to fix the waist leather and the pressing body, rotate the knob 123 in either direction to return the push button to the position where each brake is fixed. Next, tighten the knob as described above. 123 to appropriately tighten the suppressor and waist strap.

Figures 8 and 9 show a multi-function actuating device 201 that can be attached, for example, to the rear region of the waistband of a boot.

The device 201 has a storage body 202 in which a binion 2 is attached.
A knob 203 with 04 is rotatably mounted. The binion 204 meshes with a first movable gear 205 , which has an axis parallel to that of the binion and is located at the lower end 206 of the housing 202 .

Said gear is keyed to an endless screw 207 and has a tooth set 208 cooperating with complementary shaped tooth sets 209a and 209b of an opposing second gear 210 and pulley 211, respectively.
a and 208b on both sides.

The gear 210 is keyed to one end of the endless screw 207, but there is a roller between the pulley 211 and the screw 207.
A bearing 212 is interposed, and the pulley has screw 2.
Free for 07.

A cylindrical helical compression spring 213 disposed coaxially with respect to the endless screw 207 acts between opposing surfaces of the movable gear 205 and the pulley 211 to compress the first gear 20 when at rest.
5 cooperates with the second gear 210.

The third gear 214 is firmly attached to the endless screw 207 on the side opposite to the gear 210 so as to transmit the rotary motion imparted thereto to the fourth gear 215. A first helical gear 216 is keyed which transmits motion to a second helical gear 217 which is rigidly mounted.

This winder is, for example, essentially columnar and the housing 20
2) and arranged along a longitudinal axis perpendicular to that of the binion 204) 21
Consists of 8.

The shaft 218 includes an annular groove 219 adjacent to the second large gear 217 and an annular ridge 221 adjacent to the upper end 220 of the storage body 202, which is connected to the groove 219.
Both ends are between the storage body 202 and the raised portion 2.
A spring 222 is provided which is attached to 21 and 21 .

Shaft 218 rotatably attached to housing 202
A transverse threading sheet 223 for the hand 224 is provided at the end of the band 224, into which the band 224 can be inserted, for example, to close the waistbands together.

The spring 222 thus has the per se known function of facilitating the initial unwinding of the band 224 when closing the waistband.

For example, a cable 225 can be wound around the pulley 211 to tighten some restraint on the inside of the boot.

An annular groove 219 and a pulley 211 provide means for releasably stopping the rotation of the band and cable in the unwinding direction.
This means, for example, can be arranged in the groove 219, but the brake that can be applied to the groove 219 is not shown in order to simplify the illustration shown above, which consists of the covered brake 226.

The brake 226 is eccentrically pivotally mounted on a pivot 227 projecting inside the storage body 202 and is acted upon by a spring 228, making it possible to accommodate the cable 225 while preventing its unwinding. A lever (not shown) that allows rewinding of the cable 225 is further connected to the brake 226.
It is also possible to install it on

The working of the device is as follows. That is, when at rest,
The first gear 205 cooperates with the second gear 210. knob 2
03 around the dial, the cooperative relationship between the first gear 205 and the second gear 210 is maintained due to the thread direction of the endless screw 207, and this second gear transfers the movement to the third gear. It is transmitted to the gear 214, then to the fourth gear 215 and finally to the shaft 21g by means of the conical gear 216, 217.

In this way, the band 224 is wound up, and thus, for example, the waist strap is tightened.

At this stage, the pulley 211 is a roller bearing 212
I am not working because I am free to make decisions.

Conversely, rotating the knob 203 counterclockwise causes the first gear 205 to translate axially into cooperation with the set of teeth 209 of the pulley 211, during which the spring 213 is compressed. Ru.

Then, by rotating the knob 203 again in the same direction, the user can wind the cable 225 onto the pulley 211, thus achieving a second separate function.

FIG. 1O shows a multi-function operating device according to another embodiment of the present invention;
? 1i301 is shown. The device has a housing 302 rotatably supporting a knob 303 which actuates a pinion 304 cooperating with a pull wheel 329.

The pull wheel 329 is axially provided with a set of helical teeth that axially translates the first movable gear 305 .

When at rest, this gear 305 is forced by a matching spring 313 to mesh with a counter pulley 311 which is freely keyed on the same axis.

Gear 329 transmits the motion to second gear 310, which transmits it to third wheel 314. This third gear has an axis perpendicular to that of pinion 304.

The third gear 314 has an externally threaded shaft 330 to provide axial movement to the fourth gear 315, so that the fourth gear 315 moves axially relative to the shaft 330.

A spring 331 is disposed coaxially with gear 315 to encourage axial movement of the gear in the opposite direction.

The gear 315 is a fifth wheel 332 with complementary teeth.
A winder consisting of a shaft 318 is rigidly mounted, with opposite sets of teeth, and perpendicular to the winder, which is provided with a transverse threading sheet 323 and an annular ridge 321, and with which the retractable winder is provided. A spring is interposed between the body 302 and the base, and a shaft 318 is rotatably attached to the spring.

Various gears can be turned to gear 305 by rotating the knob in one direction.
is coupled to pulley 311, and at the same time gear 315 is coupled to gear 3
32, so that rotation in one direction selects only one function.

Rotating knob 303 in the opposite direction disengages gear 305 from pulley 311 and engages gear 332.

Referring now to FIGS. 11-13, another embodiment of the invention, a multi-function actuator, has an electric motor 401 housed directly in a fitted seat 402 in a ski boot portion 403. However, this motor has a shirt 404 projecting axially therefrom and a partial thread 404 on the side.

A gear 406 with complementary threads is connected to the shaft 4.
04 and a first lower set of teeth 407 on both sides.
and a second upper south set 408.

A second winder assembly 409 located below the gear 406 and a first winder assembly 410 located above the gear 406 are further coaxially attached to the shaft 404.

The pressure movement of the first and second winders is not caused by the rotation of the shaft 404.

A second winder assembly 409 is located in a plane perpendicular to the sleeve of the shaft 404 for the tensioning member of the cable 412':g and means for releasably stopping rotation in the unwinding direction. First annular groove 411 acting as a seat
a and a second annular groove 411b.

The second winder assembly 409 further includes a first complementary shaped tooth set 4 opposite the lower tooth set 407 of the gear 406.
It has 13.

The first winder assembly 410 consists of a columnar body 414 with an axial seat for the shaft 404 and at its end a third annular groove 415 and an axial through seat for a tension member such as a band 417. 416 are provided.

The end of the first winder assembly 410 opposite the upper tooth 1i 408 of the gear 406 cooperates with the gear 406, which has a second complementary tooth @418 opposite thereto.

A gear 406 is interposed between sets 413 and 418 of complementary shapes, which gear 406 meshes with either the first set or the second set, depending on the direction of rotation of the shaft 404 of the electric motor 401. be able to.

A first spring 419 and a second spring 420 are provided to keep the gear 406 in a position where it does not cooperate with the complementary shaped sets of teeth 413 and 418 when at rest, so that the second winder assembly 409 and the gear 406, respectively, and between the gear 406 and the first winder assembly 410.

A third means for releasably stopping the rotation in the rewinding direction is provided.
This means, which can be provided in an annular groove, can for example consist of a brake 421 of the type described above.

Said brake has a side surface 422 which is brought into cooperation with the wall of the groove by a third spring 423, and the separation is made by a matching rod 424 which can be operated from the outside.

The rotation of the shaft 404 of the electric motor 401 is controlled by a remote control (not shown) or by e.g. two pushbuttons 42.
5.426, etc., can be selectively adjusted in advance by a manual device mounted directly on the boot 403.

In fact, pressing one of the two pushbuttons closes the switch 427 or 428, which is adapted to rotate the shaft 404 in the desired direction.

A rod 429 is further connected to each of the push buttons 425, 426 to ensure that gear 40 is rotated when shaft 404 rotates.
6 is designed to move in translation.

A friction spring 430 is provided at one end of said rod 429 , which interacts with the peripheral edge of the gear 406 and is slidable along an inclined load surface 431 , while the first spring 419 If the friction created by the second spring 420 and the second spring 420 is insufficient, the gear 40 is free to move on the non-translating shaft 404.
6 is prevented from rotating. In the figure, only one rod 425 is inserted, and is used to assist the R1i of the low and low R1i.

Advantageously, the push buttons 425, 426 and the rod 429 are not arranged on the same diametric plane.

Of course, regarding the power source of the electric motor 401, the seat 402
There may also be a battery storage area in the boot or elsewhere in the boot.

A fourth spring 433 is further interposed between the annular ridge 432 and the third annular groove 415 on the outside of the columnar body 414, and has one end firmly attached to the columnar body and the other end firmly attached to the wall of the boot. The function of this spring is the first
The winder assembly 410 applies a load to itself while being rotated.

Therefore, the uses of the structure of the multi-function operating device are as follows.

Assuming that the cable 412 tightens a restraining body located, for example, in the boot, and the band 417 makes it possible to close the waistband starting from the state in which the waistband is closed and the foot is fixed. , release and release means brake 421
This is done by activating adaptation means such as.

When so operated, the tension member can be unwound from the winder assembly, which is free to rotate relative to the shaft 404, allowing the user to separate the waistband and move the foot. .

On the other hand, when closing the waist straps, the skier first brings the waist straps close to each other by hand, but the band 417 is wound up by the third spring 433, which has been loaded in advance.

For final fixation, the user must use the electric motor 4
01 shaft 404 to cause the upper set of teeth 408 of gear 406 to cooperate with a second set of complementary shaped teeth 418 rigidly attached to the first winder assembly. That's fine.

Of course, the electric motor 401 is equipped with an internal motor speed reducer with a safety clutch that opens the electrical circuit when the motor load exceeds a certain value.
