Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the field of ski bindings, and relates to a device for facilitating the attachment of skis to ski boots.

In particular, the present invention preloads the binteng latch device, inhibits the latch device until the ski boot is set in place, and releases the hook device to move it to the latch device. Regarding equipment.

Skiing has become popular all over the world, and many different types of ski bindings have been proposed and used.

Early bindings were simple strap-like devices that created an unreliable connection between the boot and the ski, and often separated during swings or hard turns.

This kind of binding has been gradually improved and the connections are now performed correctly.

However, this posed another problem.

In the event of a fall, the skis would not release and often caused severe injuries to the legs and ankles when the skis became tangled or plunged into the snow.

This problem has been eliminated by modern types of releasable heel and toe bindings.

In such bindings, the toe of the boot fits into the toe cup, and the heel is clamped by a spring-loaded latch against the heel of the boot or an abutment attached thereto.

The spring force can be adjusted to suit skiers of different weights and skills.

The spring load is sufficient to prevent separation during normal action, but succumbs to excessive forces created during a fall and releases the ski.

Another type achieves the same general result, but utilizes side clamps that pivot laterally to grip the side edges of a plate attached to the sole of the boot.

Typically, the load spring or resilience device is placed immediately behind the rear end of the boot.

When the ski boot is in place, the elastic device must be adjusted from an unloaded state to a loaded condition, so the skier must awkwardly bend at the waist to get close to the elastic device and adjust it. Must be.

This is not very difficult at the top of a slope in a suitable location, but becomes very difficult when a skier falls in the middle of the slope and is trying to maintain balance and replace the ski on a steep slope.

A number of heel-and-toe bindings have been proposed in which the skier steps into the binding and automatically clamps it by pressing down on the lever of the device with the heel of the ski boot and rotating the entire mechanism against the center-over spring device. ing.

Such bindings require the exertion of undesirable large forces when the skier is in a critical balancing situation, and require many links, levers,
It requires cams and springs, all of which are associated with cost and are prone to damage and breakage.

The device of the present invention overcomes the above-mentioned drawbacks and provides a simple and reliable device that provides snap-locking action of the ski binding and does not require bending to secure the boot.

Although the device was developed for a specific one of the types mentioned above, its principles can be applied to almost any type of spring-loaded binding.

Generally speaking, the present invention includes a substantially rigid hook member having at least one hook portion and a substantially rigid hook mounting body. It is incorporated into the binding.

A pair of hook devices are supported by the body and move laterally to engage the hook receiver.

A crab knit or resilient device is supported by the body and can be adjusted between an unloaded and loaded condition, and the resilient device is supported by a linkage device for transmitting the force of the resilient device to the latch device. The latch is connected to the metal device.

This type of binding is disclosed in U.S. Patent No. 3,606,370.
Disclosed in the issue.

A tread member or detent trigger is provided on the body and is movable between a first interference position and a second non-interference position.

The trigger includes a detent portion and a contact portion, and when the trigger is in the first position, the detent portion engages the linkage charge to prevent movement of the linkage into the latch device.

The trigger is spring-loaded so that it automatically moves to the interference position when the resilient device is adjusted to the unloaded condition, after which the resilient device is adjusted to the loaded condition again.

At this time, the contact part is exposed, and the ski boot is placed on the ski at the ski fixing position and then actuated by the skier to retract the detent part and move the latch device so that the latch engages with the catch part. let

In a preferred form, the mounting body includes a sole plate having a longitudinally extending recess in its underside, and the linkage includes an elongated longitudinal slot slidably disposed within the recess. It is a long and thin link with

The forward portion of the link engages the latch device for laterally moving the latch device in and out.

The rear end of the link is connected to a resilient device. A hole is formed in the sole plate directly above the slot.

The trigger includes a contact portion that slides vertically through the slot and hole, and a detent portion at the lower end of the contact portion that extends forwardly and is movable vertically into the slot.

When the resilient device is in an unloaded state, the spring forces the detent portion up into the slot and brings its forward end into contact with the forward end of the slot.

The contact portion extends above the top surface of the sole plate.

The resilient device is readjusted to the loaded position and the device is ready for locking.

When the skier places the boot on the ski fixing position and puts his weight on it, the sole pushes down on the contact area and the detent part lowers out of the slot.

The link is released and moves rearwardly in response to the force of the resilient device, moving the latch device so that the latch is fully engaged.

The detent trigger does not interfere in any way with the normal automatic release action of the binding.

Various other advantages and novel features will become apparent from the following description taken with reference to the accompanying drawings.

A ski binding incorporating features of the present invention is shown generally in FIG. 1, with the entire mounting body 10 supported by skis 12.

The body includes a heel stop and cam portion 14 and a forwardly extending portion 16 that includes a screw 18
Consists of a sole plate that is fixed to the ski with a

The rear portion 14 has two laterally spaced upright portions 20.
each having a front heel guide surface 2 for longitudinally positioning the boot when the boot is placed in the ski fixing position.
2 and a rear upper cam surface 24 used in loading the resilient device 26.

A metal member 28 is movably mounted on the sole plate of the body and moves in and out laterally to secure and release the ski boot 30.

Each boot includes a laterally extending boot plate 32 which is secured to the boot by screws (not shown), the edge of which is formed with a catch 34; As the latch device is moved inwardly, the latch device engages and grips the catch portion 34.

The construction, installation, and operation of the latch device is illustrated in the upside down exploded view shown in FIG.

The underside of the sole plate is formed with a large recess 36 having discontinuous upright side walls 38.

Each latch device 28 includes a lever arm 40 and a pivot post 44 having a central hole 60 through which the mounting screw 18 passes.
The lever arm is provided with a hole 42 at its rear end for rotatably mounting the lever arm 40 on.

The forward portion of each arm extends outwardly and rearwardly to the sidewall 38.
Generally, the planar shape guided by the notches 50 and 52 is U.
The U-shaped webs 46, 48 are formed with upright gripping jaws 54 formed at the base of each U-shape.

The inner end of each U-shape is formed with an inwardly and forwardly angled cam surface 56,58.

The linkage connecting the crab knit or resilient device 26 to the latch device 28 consists of an elongated link 62 slidably provided for back and forth movement in a longitudinal recess 64 extending below the recess 36.

The link includes an elongated slot 66 that fits into and is slidably guided by an elongated guiding and mounting rib 68 that extends upwardly from the bottom of the recess 64.

Link 62 has a T-shaped head 70 formed at its forward end, which head 70 has cam surfaces 72, 74 at its outer end.
and these cam surfaces are the cam surfaces 56.5 of the latch device.
It is angled inwardly and forwardly to coincide with 8.

When the link moves forward, the link moves the hook device laterally outward, and when the link moves backward, the link moves the hook device inward, causing the boot plate 3 to move outward.
The second receiver engages the part 34 and fixes the boot to the ski.

A cover plate 76 having an elongated hole 78 near the forward end and two guide holes 80 at the rear end that fit into the pivot posts 44 extends into the side walls 38 to retain all components in operation.

The force bar plate, on the other hand, is held in position by contact with the upper surface of the ski when the body 10 is secured to the ski.

As seen in FIGS. 1 and 6, the rear end of the link 62 includes a pair of laterally spaced upright ears 82 having a hole 84 for receiving a pivot pin 86.

The resilient device includes an elongated shank 88 pivotally connected to a pin 86 at its forward end and threaded at its rear end.

A cup-shaped washer 90 is slidably mounted on the shank, and the washer 90 receives the front end of the compression coil spring 92.

A nut 94 is threaded onto the rear end of the shank and can be adjusted to produce any desired degree of compression of the spring.

A conventional semi-circular ring 96 is pivotally mounted to upright 98 to serve as an anchor.

In the absence of the device of the present invention, with the resilient device in the position shown in phantom in FIG. 6, the skier adjusts the nut 94 to a predetermined point that provides the desired degree of compression.

The link 62 is in a free position in front of it and the washer 9
0 rests on the upper cam surface 24 and the spring is not substantially compressed.

The skier places the ski boot on the sole plate and pushes the elastic device down to a horizontal position.

Since the lower cam surface 24 is at a greater distance from the pivot point 86 than at the cam surface, the washer 90 is forced rearwardly compressing the spring 92, thus forcing the link 62 rearwardly to the position shown in FIG. Pull it to.

The engagement of the cam surfaces 74 and 56 forces the jaws 54 inwardly so that the hook fully engages the catch portion 34 and the hook.

Returning to FIG. 2, the tread member or detent trimmer 100 consists of a vertically oriented contact portion 102 and a horizontal, forwardly oriented detent portion 104 connected to the lower end of the contact portion.

The contact portion extends upwardly through the hole 106 in the sole plate and is capable of vertically sliding therein, as seen in FIGS. 1, 5 and 6.

On the other hand, the positive part of the return is as shown in Figures 6 and 7.
The forward portion of the slot 66 of the link 62 can be vertically entered and exited.

A leaf spring 108 is attached to the rib 68 with screws 110 threaded into holes 112, and the front forked ends 114 of the leaf spring are attached to bosses 116 of the sole plate to prevent lateral rotation. engaged.

When the body 10 is secured to the ski with the cover plate 76 attached, the spring 108 is fixedly supported at its rear end and slidably supported at its forward end;
It will be located just below 04.

When the spring is in its flat configuration, it elastically pushes the trigger toward its upper position.

To operate the locking mechanism in accordance with the present invention, the resilient device is pivoted upwardly to the dashed line position shown in FIG.
0 on the upper cam surface 24 and adjust the nut 96 appropriately.

However, at this time, substantially no compressive force is exerted on the spring.

The link 62 is moved to its forward most free position and the spring 108 pushes the trigger upwards so that the contact part 1
The upper end 118 of 02 extends above the underside of the sole plate;
The detent portion slides upwardly into the forward portion of the slot 66 such that the forward end 120 of the slot intersects with the forward end 1 of the slot.
22 and restrains the link from backward movement into the latch device.

When the resilient device 26 is then pushed downwardly and rearwardly to the solid line position shown in FIG. be done.

This presetting can be done by holding the skis in the hand or by placing them freely on the ground, and the skier stands with the skis on the skis and presses the button to activate the elastic device. There is no need to twist or bend your body every now and then.

After activating this mechanism, the skier should put the ski boots on the sixth
The ski boot plate is lowered into the position shown in the figure and rests on the upper end 118 of the contact portion 102 in contact with the heel guide surface 22 of the rear end.

The contact between the slot and the detent by the leaf spring prevents the trigger from moving with relatively small forces, preventing inadvertent actuation of the mechanism.

When installing ski shoes, make sure the ski shoes are placed correctly in the skier's position.
When the ski boot plate puts its weight on the trigger, the boot plate depresses the trigger and moves the detent portion out of the slot 66, ie, out of the interfering position.

The resilient device pulls the link rearward, thereby causing the latch device to pivot inwardly so that the catch portion 34 and the latch are fully engaged.

In FIG. 7, the brackets indicate the entire state. It is clear that when the trigger is in the non-interfering position, the binding operates in a normal manner, i.e. it has the function of automatically releasing the ski in response to excessive forces due to a fall.

The apparatus described in the text and shown in the drawings provides a very simple and easy-to-operate apparatus which achieves full operation at very low cost and without maintenance problems.

Although the principles of construction and operation are illustrated with respect to a particular type of binding, it will be clear that many other types and variations may be incorporated without departing from the spirit of the invention.
