Abstract

PROBLEM TO BE SOLVED: To adapt the hardness of a tightening tool element to the utilization conditions of the tightening tool while skiing by providing a movable lever for increasing the compression force of a spring accompanying the motion of a sensor and a neutralization means for obstructing the movement of the movable lever. SOLUTION: A knuckle joint 69 which is the neutralization means incorporated inside a sliding member 63 is provided with levers 70 and 71 mutually connected at a hinge connection part and the hinge connection part is positioned under a piece 2a for center alignment to be moved vertically when a main body is lifted. For instance, when the piece 2a is lifted as the result of backward falling for energizing the main body upwards, the knuckle joint 69 tends to be bent. The lever 66 and a screw 20, when they are moved before, are returned to a suspension state, that is a state where the lever 66 is supported by a wall part 68, by the spring 15. At the time, the longitudinal direction motion of a connection plate 46 is absorbed by the bending of the knuckle joint 69 and the vertical stress of a ski boot to a supporting plate is absorbed by a block.

Description

Detailed Description of the Invention

The present invention relates to elements for retaining shoes on gliding boards, especially alpine skis. The invention also relates to an assembly for retaining shoes on a sliding board, in particular an alpine ski. Second, the invention relates to a binding assembly for holding a shoe on a ski in a supported condition.

In the case of alpine skis, it is known to moor the ski boot with front and rear binding elements which hold the front and rear ends of the ski boot, respectively.

Each retaining element has a jaw which is generally carried by the body, which is connected to the ski by means of a bottom plate. The jaws are movable between a state in which the ski boot is moored and a state in which the ski boot can be released. An elastic return mechanism, typically a compression coil spring, resists movement of the jaw.

The resistance force is set by adjusting means, usually screw or bolt-like plugs, which allow adjustment of the stiffness of the spring as well as the initial compression of the spring. The adjusting means make it possible, in the usual way, to adjust the hardness of the binding element in hardness stages which are limited by the nature of the spring. Hardness refers to the stress that the ski boot must overcome in order to be released.

During skiing, this stress is not affected except by the friction of the ski shoe in the retaining jaw.

According to the German patent application published under the number 2916352, the spring is balanced with a cushioning member for resisting the compression of the spring, which increases as the open stress of the jaw increases. There is known a return mechanism that includes the above.

A mechanism of this kind allows the jaws to increase the force that the jaws have to overcome in order to release the skis, depending on the speed at which the skis urge the jaws open. Therefore, the forces to be overcome are relatively weak, usually when the skier is stationary, or at slow speeds that correspond to slow skiing conditions. Conversely, if the skier skis at a faster speed, the ski boot will bias the jaws harder and the jaws will resist opening more.

The use of this type of construction is difficult due to the need to control the cushioning member and the liquid flow therein which should not be bulky. Furthermore, in order to obtain a reliable effect, the fluidity of the liquid must be insensitive to changes in temperature.

The problem posed by the present invention is to improve the functionality of existing retaining elements.

The invention proposes to adapt the hardness of the binding element to the conditions of use of the binding element during skiing.

The present invention is substantially directed to patent application No. 29163.
The aim is to obtain the same effect as that obtained with No. 52, but to increase the restoring force of the jaw part to different information sources, especially to the bearing force transmitted by the skier to the ski with the bearing of the heel part of the ski shoe. Based on other means.

Another object of the invention is to propose a device for adapting the hardness of the binding element which is ineffective in certain situations, in particular in certain tipping configurations.

Another object of the invention is to propose a set of bindings which influence the distribution of the ski pressure on snow.

This object and the other objects appearing in the following description are achieved by the present invention as defined in claim 1.

It should be pointed out that there is known a correction mechanism that acts on the return mechanism of the jaw, which actuates the probe located under the ski boot. This kind of device is, for example, the 33rd
It is described in the published German patent application numbered 07022.

However, these mechanisms have the opposite effect to that required by the present invention. In fact, these mechanisms
To offset the increased friction between the ski boot and the jaw,
The jaws reduce the restoring force that must be overcome to release the ski boot. As will be seen below, the present invention is not incompatible with this type of mechanism.

The present invention may be better understood with reference to the following description and accompanying drawings that make up its components.

FIG. 1 shows the central part of a ski with a set of binding elements including front and rear holding elements and an intermediate connection between the two elements.

The front binding element 1 shown in the embodiment of FIGS. 1 to 6 is particularly known from the French patent application published under the number FR 2640516.

The front binding element 1 is fixedly connected to the ski by any suitable means, for example screws. Viewed from above, the bottom plate has a "U" shape that is open rearward with two lateral branches 3a and 3b.

The body is movably perpendicular to the bottom plate with a deformable connection localized in the area 9 at the connection between the body and the bottom plate. The body and the bottom plate are continuously connected at the deformable area to form a single block element.

The main body has, at its lower portion, two branch portions 3a of the bottom plate.
It is preferable to have a centering top 2a which is intended to fit between 3 and 3b.

The body 2 carries a holding jaw 4 at the front end of the ski boot. Jaw 4 includes two lateral retention wings 5 and 6 hinged to body 2 about axes 7 and 8, respectively. Jaw 4 is a bottom holder 12 for vertical holding of ski boots.
Including.

The wings 5 and 6 are movable against the restoring force applied by the spring 15 and respond to the stress of the ski boot.

The spring 15 is stored in the main body. The spring 15 is also housed within the body and activates a piston 16 which is guided within the body for longitudinal translation. The drawings show that the piston is stored in the storage part 17 of the main body.
Induced to show that the spring fits inside the piston. The front end of the spring is supported on the bottom of the piston, which is located on the front side of the binding element. On the other hand, a screw 20, the head of which is moored to the front of the body, penetrates the piston and the spring,
It has a nut 21 at the rear that moors the rear end of the spring. The rotation of the screws causes the rear end of the spring 15 to move, which allows adjustment of the initial compression of the spring.

The wings 5 and 6 are supported by shoulders 23 located above and rearward of the piston 16 beyond the hinge connecting shafts 7 and 8 of the wings of the main body to pull the piston 16 rearward. It has arm members 5a and 6a.

On the other hand, the binding element 1 comprises a bearing device for the front end of the sole of a ski boot.

The bearing device has a support plate 25 on which the sole of a ski boot is placed. The support plate 25 can be equipped with a suitable covering for facilitating lateral sliding of the ski boot, for example a PTFE (polytetrafluoroethylene) plaque on top of it. The bearing plate has approximately the same width as the ski at the level. In the embodiment shown, the support plate 25 is carried on a bearing fixed to the bottom plate 3 or hinged about a transverse axis 26 fixedly connected to the ski.

The binding element 1 shown in the embodiment of FIGS. 1 to 7 further comprises a correction mechanism for reducing the restoring force exerted by the spring 15 on the wings 5 and 6.

The mechanism includes a tilting member 30 partially housed between the branches 3a and 3b of the bottom plate 3. The tilting material is
A hinge is connected about a shaft 32 carried by the branch.

The tilting member 30 has a substantially horizontal wing 33 which can contact the rear of the binding element between the branches 3a and 3b of the bottom plate. The front part of the support plate 25 is designed so that it can ride on the ends of the wings 33.

The tilting member 30 further comprises a substantially vertical arm consisting of two lateral shoes which pass through opposite sides of the piston 16 and are each carried by a shoulder 37 which the piston has below the shoulder 23 of the wing. Have. Only shoe 35 is visible in FIGS.

Advantageously, the spring 38 puts the front end of the support plate 25 on the wing 33 of the tilting member and returns the support plate 25 to the rest state. When the ski boots are inserted, the support plate 3
It descends until it contacts 3. In this way the binding element automatically adapts to the thickness of the sole of the ski boot.

The tilting material is dimensioned such that the downward vertical stresses acting on the wings 33 are transmitted to the piston 16 in the form of stresses directed backwards, ie in the same direction as the stresses coming from the wings. The movement of the piston 16 toward the rear is accompanied by the rotation of the tilting member 30 about the shaft 32. The stresses transmitted to the piston 16 by the tilting material impose on it the stress that one wing itself must exert on the piston in order to move the piston sufficiently rearward so that the wing can be released by opening the wing. Decrease proportionally.

This mechanism offsets the increased friction between the sole of the ski boot and the bearing plate 25 in the event of a forward fall.

A small connecting rod 39 connects the tilting member to the upper part of the main body in front of the shaft 32. In case of a backward fall, the body 2 is in the area 9
Lift up with the deformation. This motion is transmitted to the tilting member by the small connecting rod 39. This causes a stress in the piston in the same direction as the stress. This offsets the increased friction between the ski boot and the sole restraint. If the stress on the sole is strong enough, the sole restraint keeps the sole of the ski boot detached upward.

Of course, other compensation mechanisms or mechanisms adapted to the thickness of the sole may be suitable.

The structure of the binding element itself is not limited. This construction is in the form of a fastener element construction compatible with the present invention. Other structures, especially other simplified structures, may also be suitable.

The overall shown in FIG. 1 also has a rear binding element 40. The binding element is of a known type. The element has in particular a movable jaw 41 carried by a body 42. In a manner also known, the body 42 is movable along the slider 43.

The assembly of bindings is located at the front of the slider 43 and is a bearing plate 44 for the rear of the sole of the ski boot.
Having.

The device according to the invention has a probe which is able to capture the stresses of ski boots.

The device further comprises a connection between the probe and the front binding element. The connection is designed to increase the restoring force of the spring against the opening of the wing at the strength of the stress captured by the probe.

In the illustrated embodiment, the probe is a bearing plate 44 located in front of the slider 43. The connection between the probe and the front binding element includes a plate 46 having a front end connected to the front binding element and a rear end movably.
The rear end has a ski boot pallet 45 that descends to the level of the support plate 44 in the presence of the ski boot. This can be seen in FIG. Depending on the case, as shown in the figure,
The plates 46 are seamed together so that the length of the plates can be adapted to the distance between the front and rear binding elements.
Consisting of

Furthermore, the slider is connected to the ski by means of a base plate 48 which is hinged about a transverse axis 49. The transverse axis is embodied in cooperation with the trailing edge of the slider and the trailing protruding edge of the substrate. A hinged connecting shaft consisting of a stop pin or other means may also be suitable. The connection between the slider and the bottom plate is designed to allow vertical suspension of the ski boot while maintaining good transmission of lateral stresses, especially when the edge bites, and the front end of the slider descends vertically. Yes, and preferably to prevent rolling between the slider and the bottom plate.

The buffer block 50 located between the slider and the substrate elastically returns the slider 43 upward so as to contact the stopper 51 fixed to the substrate, for example.
Block 50 may be replaced by any suitable means, such as a spring.

Therefore, the slider can swing vertically downward from the position determined by the stopper 51 as a starting point against the restoring force of the block 50. In particular, when the plate 46 is in the state of FIG. 6, the slider can swing downward due to the impact of the stress of the ski boot. Then support plate 4
4 is a probe which captures the vertical stress of the ski boot, more precisely the change in the bearing stress exerted by the rear end of the sole of the ski boot.

FIG. 6 best shows the connection between the plate 46 and the slider 43. Below the support plate 44 is a tilting member 52 which is hinged about a transverse axis 53 carried by the bottom plate 48. The tilting member has a horizontal branch 55 that fits under the slider, and when the plate 46 is in a low position, a substantially vertical surface against which a complementary surface 57 located at the rear end of the plate contacts. It has a bearing surface.

In this manner, the downward swing of the slider causes the tilting member 52 to bear against the rear surface 57 of the plate 46, causing the tilting member to rotate and the plate 46 to move forward.

The plates 46 are preferably connected at the front by a hinge connection and are biased upwards at the level of their rear ends by means of a device which becomes the brake 58 of the ski. The device comprises, inter alia, two hinged arms 59 which are spring-backed.

The front binding element is mounted on a base plate 62 which is fixedly connected to the ski. The base plate extends between the bottom plate and the ski. The substrate is a sliding member 63.
Has a longitudinal housing into which is guided. The sliding member emerges from the rear part of the base plate and is connected to the front part of the plate 46, for example by means of a hinged connection, which is provided in a complementary form.

The connection, on the other hand, is established by a flexible tongue 64 which is fixed at each end to the substrate and plate 46 respectively. Any other connecting means may be suitable.

At the front, the sliding member is supported on the lower end of the lever 66. The lever enters into the body 2 with a vertical recess 67 located in the front, the central part of which is penetrated by the screw 20 and is supported under the head of the screw. Its upper end leans against the body over the screw. Sliding member 63
Under the action of, the lever 66 is supported on the main body 2 and acts on the screw head in this manner. At rest,
The screw head is formed by removing the lever 66 from the wall portion 68 of the hollow portion 67.
In close contact.

For example, at the end of rotation in the maneuvering phase, if the skier bears more strongly at the rear, it causes the probe 44 to descend and the slider 43 to swing downwards against the elastic restoring force of the block 50. . The connecting plate 46 is pushed forward by the rotation of the tilting member 52. This movement is lever 6
6, the lever forces the screw 20 to move forward. The spring 15 is further compressed, making it more difficult to open the wings 5 and 6. This functional stage of the device is shown in FIG.

When the ski boot is no longer stressed, the screw 20 and lever 66 are returned to their original condition, that is, the lever is supported on the wall 68 of the body.

According to one characteristic of the invention, the device comprises means for disabling the action of the sliding member on the spring in certain situations, in particular in the case of some falls. In the case of a rearward fall, for example, each ski boot of the skier exerts an upward stress on the jaws of the front binding element and supports the heel of the ski boot, here the support plate 4
A downward stress is applied to No. 4. However, in this situation increasing the hardness of the spring is not desirable.

In the embodiment shown in the figures, the disabling means is
It is shown in the form of a knuckle joint 69 incorporated in the sliding member 63 ridge. Knuckle joint 69 includes two levers 70 and 71 interconnected by a hinged connection. The hinged connection is located below one element of the body that moves vertically when the body is lifted. The element is advantageously a centering top 2a which passes through the bottom plate 3 of the holding element. In the resting state of the body, the top 2a, while not fully extended, keeps the knuckle joint flat in an extended state close to it. Furthermore, the hinge connection of the second lever can be moved longitudinally under the top by the movement of the sliding member 63. In some cases, padding or some other suitable means can be scheduled to prevent the knuckle joint lever from reaching and exceeding full extension.

Therefore, in the state shown in FIG. 3, the knuckle joint can play a role of transmitting the longitudinal stress coming from the connecting plate 46. The knuckle joint can also force the longitudinal movement transmitted from the connecting plate 46 on the assembly of sliding members. Taking into consideration the fact that the knuckle joint is in a stretched state, the vertical reaction induced by the top 2a is relatively weak.

For example, when the top 2a is lifted up as a result of the backward fall of the body urged upward, the knuckle joint tends to bend. If the lever 66 and the screw 20 have moved in front of them, the spring 15 causes the lever 66 and the screw 20 to rest, that is, the lever 66.
Are returned to the state of being supported by the wall portion 68. The longitudinal movement of the connecting plate 46 is then absorbed by the bending of the knuckle joint, and the vertical stress of the ski boot on the bearing plate 44 is absorbed by the block 50.

The action that the displacement of the connecting plate might have had on the compression of the spring is therefore neutralized.

In parallel with this, the correction mechanism of the holding element is activated by lifting the main body. The small connecting rod 39 translates upward and causes the tilting member 30 to rotate. The tilting material exerts pressure on the piston 16 with its shoe, which stresses come from one or the other wings which are biased open. Therefore, the release of the ski shoes becomes easy.

This stage of functioning of the retaining element is illustrated in FIG.

If the stress is not sufficient to cause the release of the ski boot, the body will return to its original state when the stress ceases. The tilting member 30 pivots toward its original position,
By lowering the top a, the two levers of the knuckle joint are returned to a substantially straight line, and the knuckle joint is again in a state of transmitting the longitudinal movement of the connecting plate and the stress to the lever 66.

On the other hand, the binding element correction mechanism is active in the case of a forward fall, ie a fall in which the front of the ski boot exerts a strong pressure on the support plate 25. In fact, in this case, the support plate 25 causes the tilting member 30 to exert a stress that acts on the correction mechanism in the same manner as the stress caused by the backward fall. In particular, the support plate 25 transfers bearing stress to the tilting member 30, which tilts member transmits the stress to the piston 16. in this case,
Opening the wings becomes easier.

However, the main body of the holding element cannot be lifted because there is play in the connection between the tilting member 30 and the small connecting rod 39. In this case, there is no change in the opening of the knuckle joint 69.

The above case of fall and the functional form of the correction mechanism are not limited to the present invention. Disabling movement of the connecting plate could also occur in a forward fall. In fact, the tilting material 30
It would be sufficient to replace the playful connection between the and the small connecting rod 39 with a playless connection. There could be no correction mechanism, a correction mechanism that would be active in the case of a forward or backward fall, or any other suitable correction mechanism.

Further, it should be noted that the degree of bending of the knuckle joint 69 can be changed by changing the position of the top with respect to the joint area 9 of the body or the length of the small connecting rod. In this regard, this tip is not limiting as an element for controlling the disabling means of the knuckle joint, but any other suitable element, for example one branch of the tilting element 30, or the bearing plate 25, or An element controlled by the support plate could ensure the control function.

Knuckle the flexible area of the lamella where the buckling deformation is controlled by the action of the stress transmitted by the connecting plate 46 in response to the vertical state of one element of the body located in the deformable abdominal area of the lamella. It could be used instead of a fitting.

FIG. 10 shows a modified embodiment of the present invention.
The figures show a front holding element 81 of the same type as the front holding element, to which a connecting plate 83 is connected. The other parts of the binding element assembly are the same as above.

The front binding element 81 is essentially the same as the element described above. The difference lies in the level of means for connecting the sliding member 86 and the front binding element. The function of the means is here to control and even stop the movement of the sliding member when the action of the sliding member is not desired.

To illustrate this, the illustrated retaining element has a centering top 87 with an opening 88 through which the sliding member 86 extends. Depending on the case, as shown in the figure,
In this area, the thickness of the sliding member is reduced in the front.

The centering top has at its bottom a shoe 89 which defines the bottom of the opening 88.

When the main body is in a normal state, that is, in the state shown in FIG. 10, there is a gap between the shoe 89 and the lower surface of the sliding member 86.

For example, in the case of a backward fall, the top 87 is lifted, which causes the shoe to come into contact with the sliding member.
Therefore, the movement of the sliding member is controlled. The control may vary in strength due to the nature of the surface of the shoe and the surface of the sliding member that contacts it. It is also possible to allow the unidirectional control by means of the asymmetric tooth profile, i.e. to stop the sliding member in the forward direction of movement, but to allow a rearward return movement.

The control also includes a block of deformable material,
For example, an elastomeric block can be gradually added by inserting it between the shoe and the sliding member.

Other variations or structural forms may be suitable.

As in the previous case, the action of the movement of the connecting plate with respect to the spring is neutralized in certain situations, for example in the case of a rearward fall. As in the previous case, the same result can be achieved in the case of a forward fall or any other type of fall.
Furthermore, the control action of the sliding member can be used in combination with a correction action, for example, a correction action according to any one of the above methods.

FIG. 11 shows another modified embodiment of the present invention. According to this variant, the support plate 90 on which the front or the ends of the ski boot rests is held in suspension by a spring 91 or some other suitable means, for example an elastomeric block. Below the end of the suspension-like support plate is a vertically slidingly mounted locking device 92.
The locking device has a central storage section through which the sliding member 93 passes. The housing is defined below by the upper surface of the control shoe of the sliding member. A spring 96 or some other suitable means elastically returns the locking device upwards. The assembly allows the locking device 92 to spring 9 when there is no strong downward stress exerted by the ski boot on the support plate.
It has the size and the characteristic of being returned to the upper side by 6. The locking device controls the movement of the sliding member towards the front. In some cases, the shoe and its contact with complementary teeth or some other suitable means to allow the sliding member to return to the rear, but to provide unidirectional control to stop the movement of the sliding member toward the front. The surface of the sliding member can be coated.

When a strong stress acts on the support plate, the support plate is lowered sufficiently for the shoe 95 to release the sliding member. Therefore, the sliding member acts on the rear support plate, and the lever 97 can be pulled forward by the impact of the stress transmitted by the connecting plate.

The invention is not limited to the various structures described, but it is intended to include all modifications and equivalents as well as the structures generally defined in the opening claims.

In particular, the invention is not limited to the described front binding element. The invention applies to any other known construction of front binding elements.

The invention is not limited to the case where the probe is arranged on the rear binding element. The probe causing the longitudinal movement of the sliding member could be located in other areas of the boot.

The movement of the probe is not always vertical. The probe could also capture the rolling stress at the front or rear end of the ski boot.
