Display device for setting the compressive force of a resilient member in a safety binding for skis

The invention relates to a display device for adjusting the pressure force of the resilient member of the release mechanism in a safety binding for skis, with a housing and an attached or arranged thereon transparent window, with a scale that shows different pressure force values and behind which the corresponding one Adjusting member is recognizable or a pointer attached to this appears.

In such a bond, the release hardness depends on the initial pressure of the respective elastic organ is generally designed as a spring. In order to be able to change this pressure force, an adjustment element is provided, that exerts pressure on one end of the resilient organ and that acts as a screw or nut.

030036/0595

can be performed within the housing of the binding is arranged movably.

Many bindings have an indicator for the compressive force of the spring so that one can use this compressive force set and thus achieve the desired release hardness. Generally, such display devices have the shape of small plates with markings or a scale, and through a transparent window you can see the setting element or recognize a pointer rigidly connected to it. In the former case, the reference element can be whole simply serve the end face of the adjusting member, which rests against the associated spring. The position of this plane relative to the scale attached to the plate then gives the user the setting hardness of his bond.

A binding of this type is known from FR-A 2 o48 87o, in which the display device consists of a pointer in the form of a nut, which is movably mounted on a threaded spindle, and as a support for a spring serves. The device also has a plate provided with markings through which the mentioned pointer is recognizable. In addition, the plate is covered with a transparent one, probably serving as a seal Plate covered. The panels are riveted together in a recess of suitable complementary contour. A calibration is not possible.

So that the release hardness of the binding can be set with sufficient accuracy, it has proven to be It was found necessary to first carry out a calibration so that the value shown on the display plate

corresponds exactly to the elastic compressive force exerted by the spring. Such calibration is because of unavoidable and sometimes quite considerable variations between the various types used to manufacture the ski bindings serving individual parts occur, quite indispensable; this is especially true for the springs.

A number of display devices have already become known with which the manufacturer can carry out a calibration in advance can. The devices proposed so far are relatively complex, and their Construction requires at least one additional operation when the initial calibration is carried out shall be.

For example, in the French patent application 2 328 956 describes a display device in which the marker pointer is not located on the one used as the setting element Mother but located on a second mother who is screwed onto the same threaded spindle and which is moved in one of the two directions to the required To carry out initial calibration. The disadvantage of such The device is that two separate organs are required, on the one hand to compress the spring and on the other hand to display the setting, which increases the number of individual parts and thus the manufacturing costs. In addition, the calibration process made possible by such a device is suitable for large-scale production poorly suited, because the worker has to adjust the second nut by hand every time it is tied. This process takes a long time and can be done incorrectly.

030036/0595

The present invention is therefore based on the object of developing a display device with which the required calibration can be carried out very easily and its structure is particularly simple and inexpensive.

This object is achieved in a display device of the type mentioned in that the scale is on a plate is located, which is displaceable in the adjustment direction of the adjustment member before it is directly or indirectly is fixed in position on the housing, and that the plate is provided with a stop element, that is able to lie against the reference surface of the setting element or the pointer attached to it and that can be removed or rendered ineffective after installation.

In an expedient embodiment of the invention, the plate is an inner plate which is in a recess in the housing is slidably arranged before a connectable with her outer plate is attached, the position of which on the Housing is unchangeable. In this case, fixing means are expediently provided for the inner plate, the final Make determination of the inner plate when the outer plate when attached to the housing against the Inner plate is pressed.

Further expedient refinements of the invention are characterized in the subclaims.

The calibration is very easy with this device carry out. The setting element must be brought into a position for which the release hardness has a specified value the mark or number on the scale

030036/0595

corresponds to the plate at the location of which the stop element carried by the plate is located. Then needs this plate only needs to be inserted into the housing, and its stop element against the reference surface of the adjustment member to be guided or the resilient means acting on them take care of this application to the adjusting member, after which the fastening of the plate in its place in the housing (directly or indirectly through the outer plate) automatically brings about their definitive determination in the corresponding position, i.e. in the position for which the required calibration has actually been carried out. The calibration can therefore be carried out very easily and without additional work make.

The binding toe piece shown in FIGS. 1 and 2 consists of a binding housing 1 and a section 2 in the form of a spread jaw that can accommodate the tip of a ski boot. The case 1 is around a stationary pin 3 with a vertical axis ν is designed to be rotatable. By rotating this housing you can the boot will break free when excessive pressure is exerted on the skier's lower leg.

The rotatable housing 1 is held in its normal position on the ski by a resilient mechanism, which is a compression spring 4 contains, which acts on a piston 5 and presses it against a cam 6, which has the shape of a slightly has a concave flat in the pivot 3. The adjusting element for the initial pressure of the spring 4 is a terminal pin 7, which is screwed into the housing 1. By screwing this locking pin in or out the user can determine the level of the initial compressive force of the spring 4 and thus the hardness of the release mechanism

030036/0595

- 12 -

of the pivoting housing 1 change.

The display device for setting with which the present jaw is equipped has two adjacent one another Plates on, namely an outer plate 8 and an inner plate 9; in the illustrated embodiment the two plates lie on top of one another because they are arranged on top of the binding housing. The plates should be in one of two recesses 1o and 11 in each case are fastened in the housing 1. In the bottom of the recess an opening 12 is cut through which one did face 13 of the adjusting pin 7 can see that it is supported on the spring 4 and that it serves as a reference element for identification the position of this adjusting pin is intended to serve.

The outer plate 8 has a transparent window 14 through which the digits 2, 3, 4, 5 and 6 one The scale can be seen, which is attached to the top of the inner plate 9. These digits are on the two Attached longitudinal edges of a longitudinal opening 15 cut into this plate; one looks up through the opening the reference surface 13 of the adjusting pin 7. In addition, the inner plate 9 carries a nose 16 on its underside, which on the Is the location of a specific number on the scale on this plate; in the example shown this is number 3.

The outer plate 8 should be in an unchangeable position on the housing 1 of the jaw inside the area provided for it Recess 1o are attached; fastening can be done with rivets 17 or in another suitable manner. In contrast the inner plate 9 is to be fastened in a non-fixed position in order to achieve the required calibration

030036/0595 - 13 -

can be made. For this purpose, the recess 11 has this Plate has a length L1, which is slightly greater than the length L2 of the plate, so that this plate is in the axial direction can be moved as long as the outer plate has not yet been set.

In addition, fixing means are provided with which the inner plate finally has the desired calibration corresponding position can be fixed unchangeably, and that happens during the fastening of the outer plate 8. In the example shown in FIGS. 1 to 12, the fixing means consist of one group Ribs 18 with a fine burr extending on the top of the Inner plate 9 are located and which press into the adjacent side of the outer plate and anchor therein when this panel is secured in place and pressed against the inner panel. To the inner panel To be able to set completely, the ribs 18 of this plate must of course protrude from the recess 11, and in addition, the material of the inner plate must be harder than that of the outer plate. On the other hand, the Ribs 18 can of course be replaced by a group of other suitable projections such as teeth or wedges.

Finally, the outer plate 8 has a resilient tab 19 on its inside, which as a means for exercising a Thrust is used on the corresponding end of the inner plate; this will be described in more detail.

To make the previous calibration of the display device, the spring 4 of the spring mechanism must be in one predetermined compression state, which is a given

030036/0595

exact value corresponds to the release hardness, in the present case, for example, a value that is indicated by the number 3 marked on the scale on the inner plate 9. This setting can be made with a suitable control device by turning the adjusting pin 7 in more or less far, and that can already be done with the Work step that precedes in which the display device according to the invention is installed will.

The worker performing this work step first places the inner plate 9 in its recess 11, with a slight play j between the stop lug 16 of this plate and the reference surface 13 of the adjusting piston 7 must remain (see Figure 1o). Then the worker places the Outer plate 8 in its recess 1o and places the resilient tab 19 of this plate against the associated end of the Inner plate 9, as shown in FIG.

This resilient tab serves as a pressure-exerting member for the inner plate 9 and exerts a pressure in the direction of the arrow g until the stop member 16 rests against the reference surface 13 of the adjusting pin 7. From now on it is the inner plate 9 properly aligned because the number 3 of the scale of this inner plate is now exactly with the reference surface 13 of the adjusting pin is aligned, since, according to the construction, the contact member 16 is at the location of this Digit is located.

You now only need to fasten the outer plate 8 with the aid of rivets 17, because this simultaneously Define the inner plate 9 in the corresponding position

- 15 030036/0595

nitively determined. The inner plate is pressed by the outer plate so that its ribs 18 into the less solid material of this plate penetrate (compare FIG. 12).

As a result, no special work step is required, around the inner plate 9 in its exact position, which corresponds to the previous calibration of the present device, to fix.

It can be seen that the stop lug 16 is arranged so that it will eventually be eliminated or made ineffective; she only provides a temporary stop element for determining the exact position of the inner plate 9. To remove the nose, it can be bent outwards, for example, with the front end of the Adjusting pin 7 is equipped with a bevel that bends the nose when the pin 7 later in the direction of arrow h is screwed. But it would also be possible to break off the nose completely.

Figures 13 to 18 show another ski binding that is also provided with a display device according to the invention, but a second embodiment of the Invention corresponds. This binding, for example as a heel machine to hold the heel of a ski boot can be executed, has a housing 2o, in the interior of which the spring 21 of the associated release mechanism is located. The adjustment member provided in this binding consists of a nut 23 on a Screw 22 runs, but is prevented from rotating.

030036/0595

The head of the screw is externally accessible so that the nut can be moved in one of two directions. The end face 25 of the nut 23, which rests against the spring 21, simultaneously represents the reference surface with which the exact position of this organ and thus the value of the compressive force of the spring can be determined.

The display device provided on the present binding is the same as that of the device described above of two adjacent plates, namely an outer plate 8a and an inner plate 9a. In contrast to the In the design described above, these two plates are much smaller due to a resilient retaining tab 26 Strength linked together. These two plates thus represent a one-piece component that is in a single Work step can be injected from suitable plastic.

As before, a wide transparent window 14a is provided in the outer panel 8a. However, the Inner plate 9a in turn has a similar window 27, under which there is a stop lug 16a, the the reference surface 25 of the adjusting nut 23 is to touch. In the present case, this nose is at the location of the Number 5 of the scale provided on the top of the inner plate 9a.

Since this plate is to be pierced by the rivets 17a for fastening the outer plate, there are two in it Holes 28 are provided for the rivet to pass through, and these holes are elongated so that the inner plate, before securing the outer panel in place, in

030036 / 059B

Can shift axis direction. In contrast, the holes made in the outer plate have a diameter that corresponds exactly to that of the rivets 17a, because these plates are fixed in an unchangeable position should, while only the position of the inner plate can be changed in order to carry out the initial calibration of the device can.

The calibration process proceeds in the same way as in the previous case. You only need the adjusting nut at first 23 to be brought into a position that helps to achieve a release hardness that corresponds to the scale value at the location, on which the stop member 16a is located, in the present case the number 5 of this scale. The worker who the Display device is to mount, then brings it into the recess 3o, which is provided in the housing 2o, and although, as shown in FIG. 16, that is, by a slight play j between the stop lug 16a of the inner plate and the reference surface 25 of the nut 23 is maintained. Then the worker lays the outer plate 8a on the inner plate by also inserting it into the recess 3o.

But this leads to the fact that the thin end 31 of this plate, which faces away from the retaining tab 26, is against the corresponding Edge of the recess places. This leads to a pull on the inner plate 9a in FIG Direction of arrow F1 until the nose 16a is against the Reference surface 25 of the nut 23 places (see Figure 17).

From this moment on, the inner plate 9a is in the correct position and the required calibration is carried out correctly. The number 5 on the scale is automatically aligned

030036/0595 - 18 -

with the reference surface of the nut 23, because the design of the stop member 16a is at the location of this number is located.

One now only has to finally fasten the outer plate 8a with the aid of the rivets 17a, because this is done at the same time the inner plate 9a held in its calibration position, with the aid of fixing means provided for this purpose. It should be noted that these consist of ribs or teeth 32 in the present case, which are formed in the bottom of the recess 3o and which can anchor themselves in the underside of the inner plate 9a, if this is clamped by the outer plate when attaching this outer plate. Finally, as before, the stop lug 16a can be made ineffective or eliminated during the first subsequent actuation of the adjusting nut 23.

The display device according to the invention enables both cases quite simply a previous precise calibration of the position of the scale fitted in the device. From the moment the spring's initial compression is set to the intended value, it is Calibration is carried out automatically without any further action on the part of the worker, because the one carrying the display scale The inner plate is automatically pushed back by the resilient means provided for this purpose; as such means can for example, the resilient tab 19 from Figures 1 to 12 or the resilient retaining tab 26 from the Figures 13 to 18. The worker therefore only needs the two plates that represent the present device, in place and attach the outer panel in a perfectly normal process, with none

- 19 030036/0595

Special precautions must be observed because this outer panel is always in an unchangeable position is attached. Fixing this plate in its intended place, in turn, ensures the final one Fixing of the inner plate in the exact position corresponding to the required calibration.

It should also be noted that this result can be achieved with a very simple and inexpensive device. In addition, the device can be used on a toe piece, as shown in FIGS is, but also on an automatic heel, as shown in Figures 13 to 18.

The display device according to the invention can be used in many Modify respect. For example, the stop lug arranged on the inner plate, which is the one for the inner plate The required position can be replaced by any other suitable stop element. as well can the resilient organs that act on the inner plate must, in turn, be designed differently in order to guide them into the intended position. So you can call it run independent organ of both plates, for example as a leaf spring. The outer plate can also be opened Secure in place other than by riveting, for example by snapping into place or by gluing.

Finally, the display device according to the invention just as well use when the element making the position of the setting element visible than its Stop surface is formed on the spring, as in

030036/0595

is the case in the above examples, but also when this visualization is made by a pointer, which is arranged on the corresponding setting element. In the latter case, the structure is so that the stop element the inner plate is supported on this pointer in order to carry out the required calibration.
