Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a closure and foot fixation device for rear-entry ski boots.

(Prior Art) The structures of plastic ski boots that have become popular in recent years can be roughly divided into two types: front entry type and rear entry type. Rear entry type ski boots are a type of ski shoe that has been increasing in recent years.The outer shoe consists of a front cuff, rear cuff, and shell.The lower part of the front cuff and rear cuff is attached to the shell with rivets, and the rear cuff can be opened and closed. It is a familiar thing.

A skier who wants to wear these ski boots opens the rear cuff and inserts his/her foot into the inner boot, then passes from one side of the front cuff, behind the rear cuff, and then to the other side of the front cuff. Pass the ratchet belt through the ratchet holder and tighten it with a buckle, or as shown in JP-A-61-119201, wires passed on both sides of the front cuff can be wound up using a winding drum. Thus, the front cuff and rear cuff are closed.

However, passing the ratchet belt through the ratchet holder, tightening the buckle, and winding the wire with the winding drum involve many operations and are time-consuming.

Furthermore, unlike front-entry ski boots, rear-entry ski boots have a buckle that almost only serves to close the front cuff and rear cuff, and cannot tighten the whole foot with equal pressure, so the foot and ski There is a gap between the shoes and the shell, making the fit of the ski shoes worse.
This has the disadvantage that it also has a negative effect on the maneuverability of the ski.

For this reason, in rear-entry ski boots, a counter is installed between the shell on the top of the instep and the inner boot, and a foot fixing device is installed that pulls the counter with a wire to tighten the instep. , the commonly used method is to secure the foot to the shoe.

The foot-locking device that pulls this counter with a wire is usually installed on the rear cuff, so after tightening the buckle that closes the front cuff and rear cuff, the skier operates the foot-locking device installed on the rear cuff. Because the feet need to be fixed in the shoe, the number of movements required to put on the ski boots increases, making the boots difficult for beginners, women, and children to use.

Therefore, ski shoes that can close the front and rear cuffs and secure the feet at the same time have been proposed. The opening/closing angle is very narrow, making it difficult to insert the foot. Also, JP-A-62-
The ski boots No. 64301 consist of two levers, one for closing the rear cuff and one for securing the foot to the ski boots, which increases the number of movements needed to put on the skis and This has the disadvantage that the number of parts of the device itself increases.

(Problems to be Solved by the Invention) Therefore, the present invention provides a ski shoe that can close the front cuff and rear cuff with a single action using a single lever, and further provides a ski shoe that can close the front cuff and the rear cuff with a single action using a single lever. These ski shoes can not only close the rear cuff, but also secure the foot.The opening and closing angle of the rear cuff is sufficient, and the closing strength of the front and rear cuffs, as well as the tightening strength of the instep, can be finely adjusted, making them suitable for beginners, women, and children. The purpose is to provide a rear-entry ski shoe that is easy to handle.

(Means for solving the problem) A rear entry shoe in which the front cuff, rear cuff, and shell constitute the outer shoe, and the lower part of the front cuff and rear cuff is pivoted to the shell with rivets, and the rear cuff can be opened and closed. The type ski boots include a lever 1 rotatably pivoted to a base 2 fixed to a rear cuff, a slit member 3 fixed at a position where the lever 1 is accommodated and having a slit 31 on the side surface, and one end of which is attached to the lever. 1, and the other end is pivoted 32 so as to move within the slit 31 of the slit member 3. The lever 1 has a slit 9 that vertically passes through the lever 1, and the slit 9 A stopper pin 7 that is inserted through the slit 9 is fixedly attached to the arm 4, and one end of the arm 4 on the lever 1 side is connected to the lever 1.
It is pivoted 21 so as to be movable within the slit 20 on the lower surface, and the range of movement is restricted by the stopper pin 7, and the wire F fixed to the front cuff is connected to the slit member 3 of the arm 4. This is a closing device for a rear entry type ski boot which is fixed to a shaft attachment part 32.

Note that the rear cuff may be provided with a protrusion, tunnel, pulley, etc. for changing the direction of the wire F led from the front cuff to this closure device.

Furthermore, in rear-entry ski boots in which a counter is provided between the shell on the upper surface of the instep and the inner boot to secure the foot by pulling it with a wire, the lever 1 is moved on the lever 1. The wire G for fixing the counter is guided from the hole J in the upper part of the rear cuff to the moving body 15 of the device and fixed.

In the hole J at the top of the rear cuff, in order to smooth the movement of the wire G for fixing the counter,
A pulley may be attached.

(Function) Since the present invention is constructed as described above, the stopper pin 7 in the slit 9 can be moved in order to adjust the strength of closing the front cuff and the rear cuff. When the stopper pin 7 is moved toward the base 2, the strength of closing the front cuff and the rear cuff becomes weaker, and when the stopper pin 7 is moved away from the base 2, the strength of the closure becomes stronger. As a method for freely fixing the stopper pin 7 at any position within the slit 9, there may be a method of attaching the stopper pin 7 to a trigger, or tightening the stopper pin 7 with a nut.

First, to explain the case where the strength of closing the front cuff and rear cuff is maximized, the stopper pin 7 is preferably moved to the farthest position from the base 2 within the slit 9. The stopper pin 7 is connected to the arm 4 which moves within the slit 20 on the lower surface of the lever 1.
Because it works to suppress the movement of the shaft attachment part 21,
The shaft attachment part 21 is fixed at the farthest position from the base 2.

A skier who wishes to wear this rear-entry ski boot first raises the lever 1 in a direction perpendicular to the back of the rear cuff. Since the lever 1 side of the arm 4 is restrained from moving by the stopper pin 7, the shaft attachment portion 32 of the arm 4 to the slit member 3 moves within the slit 31 to the position closest to the base 2. Since the wire F fixed to the shaft attachment portion 32 of the arm 4 to the slit member 3 also moves to the position closest to the base 2, the wire F becomes loosened. Therefore, the skier is able to expand the rear cuff.

After opening the rear cuff and inserting the foot into the inner boot, the lever 1 can be pushed down to the back of the rear cuff. When the lever 1 is pushed down to the back of the rear cuff, the shaft attachment part 32 of the arm 4 with the slit member 3 moves in the slit 31 in the direction furthest from the base 2, and the slit member of the arm 4 moves in the direction farthest from the base 2. Since the wire F fixed to the shaft attachment part 32 of the cuff 3 is also furthest away from the base 2, the tension of the wire F is maximized, and the closing strength of the front cuff and rear cuff is the strongest.

Note that if a protrusion, tunnel, or pulley H is provided on the rear cuff in order to change the direction of the wire F guided from the front cuff to the shaft attachment part 32 between the arm 4 and the slit member 3, the movement of the wire F will be further reduced. It is smooth and easy to operate.

Next, a case will be described in which the strength of closing the front cuff and rear cuff is made the weakest.The stopper pin 7 is preferably moved within the slit 9 to the position closest to the base 2. In this case, the stopper pin 7 does not at all suppress the movement of the shaft attachment portion 21 of the arm 4 that moves within the slit 20 on the lower surface of the lever 1.

To put on ski boots, when lever 1 is raised perpendicular to the back of the rear cuff, arm 4
Since the lever 1 side of the
Move inside toward base 2. Therefore, arm 4
The shaft attachment part 32 with the slit member 3 is also connected to the slit member 3.
1 toward the base 2, but simply raising the lever 1 does not move it to the position closest to the base 2 within the slit 31.

Therefore, when force is applied to expand the rear cuff, since the pivoting part 21 of the arm 4 on the lever 1 side is not restrained by the stopper pin 7, the pivoting part 21 moves inside the slit 20 from the base 2. Since it is movable again in the farthest direction, the shaft attachment part 32 between the arm 4 and the slit member 3 to which the wire F is fixed can further move within the slit 31 to the position closest to the base 2. become. Therefore, the shaft attachment part 32 between the arm 4 and the slit member 3, to which the wire F is fixed, will loosen until it is closest to the base 2, similar to when the stopper pin 7 is moved farthest from the base 2. .

In this way, even if the closing strength of the front cuff and the rear cuff is adjusted by the stopper pin 7, the fixed part with the slit member 3 that restricts the movement of the wire F (the part where the arm 4 and the slit member 3 are attached) 32 always moves within the slit 31 to the position closest to the base 2, so the opening/closing angle of the rear cuff when inserting the foot can always be maintained at a constant angle.

After putting on your ski shoes and inserting your feet into the inner boots, push lever 1 to the back of the rear cuff.
The shaft attachment portion 32 of the arm 4 to the slit member 3 moves within the slit 31 in a direction away from the base 2. However, the shaft attachment part 21 of the arm 4 on the lever 1 side
Since the arm 4 is not restrained by the stopper pin 7, the arm 4 succumbs to the resistance of the wire F fixed to the shaft joint 32 between the arm 4 and the slit member 3, and the shaft joint 21 on the lever 1 side presses against the stopper pin. 7
to the position closest to the base 2, which is suppressed by
It will be pushed back inside the slit 20. Therefore, the shaft attachment portion 32 between the arm 4 and the slit member 3 is stabilized at a portion of the slit 31 close to the base 2, and the wire F fixed to the shaft attachment portion 32 also approaches the base 2. , the tension of the wire F becomes the lowest, and the closing strength of the front cuff and rear cuff becomes the weakest.

If the stopper pin 7 is placed at an arbitrary position between the farthest position and the closest position to the base 2 in the slit 9, when the lever 1 is tilted, the stopper pin 7 will connect to the arm 4 and the shaft attachment part 21 on the lever 1 side. Since the arm 4 is prevented from moving toward the base 2 within the slit 20 midway, the shaft attachment portion 32 of the arm 4 with the slit member 3 also does not move any further toward the base 2. Therefore, since the wire F fixed to the shaft attachment part 32 of the arm 4 and the slit member 3 is located between the position furthest from the base and the position closest to the base, the tension of the wire F is at the intermediate position. The closing strength of the front cuff and rear cuff is also intermediate.

In this case as well, the shaft attachment part 21 of the arm 4 on the lever 1 side is not restrained by the stopper pin 7 in the direction away from the base 2, so when the lever 1 is raised, the wire F is fixed. Since the pivoting portion 32 between the arm 4 and the slit member 3 can be moved to the position closest to the base 2, the opening/closing angle of the rear cuff can always be maintained at a constant angle.

Furthermore, in rear-entry ski boots in which a counter is provided between the shell on the upper surface of the instep and the inner boot to secure the foot by pulling it with a wire, a movable body 15 is attached on the lever 1. The wire G for fixing the counter is fixed to the movable body 15 on the lever 1 through the hole J in the upper part of the rear cuff.

The wire G is led to this device through the hole J at the top of the rear cuff, and there is a distance between the hole J at the top of the rear cuff and the base 2, so when the lever 1 is raised, the wire G becomes loose and the lever 1 Wire G becomes tense when it is defeated. and,
By moving the movable body 15 on the lever 1, the wire G fixed to the movable body 15 also moves, and the tightening strength of the wire G can be adjusted accordingly.

Therefore, by using this device, the front cuff and rear cuff can be closed with a single lever action, and at the same time, the counter provided between the shell on the top of the instep and the inner boot can be closed using a wire. It can be towed to secure the foot to the shoe. Furthermore, it is now possible to fine-tune the strength of the front and rear cuffs and the tightening strength of the instep.

Furthermore, by attaching a pulley to the hole J at the top of the rear cuff, the wire G for fixing the counter moves smoothly, making it easier to operate the lever.

(Example) Fig. 1 shows an example of the present invention implemented as a closing device for a front cuff and a rear cuff.
In order to freely fix the stopper pin 7 at any position within the lever 1, as shown in FIG. A trigger 6 having a stopper pin 7 is attached. With this structure, the trigger 6 having the stopper pin 7 is fixed by engaging with the tooth surface 8, and can be moved to any desired position by disengaging from the tooth surface 8.

FIG. 5 shows another embodiment for fixing the stopper pin 7 at any position within the slit 9.
The stopper pin 7 can be fixed by tightening the nut 10 that is screwed into the stopper pin 7. In this case, nut 10 and lever 1
If a washer 11 is inserted between the washer 11 and the lever 1 is designed so that the washer 11 and lever 1 engage with each other as tooth surfaces, the stopper pin 7 can be fixed more reliably.

Although two examples have been given above, the method is not limited to these methods as long as the stopper pin 7 can be fixed at any position within the slit 9.

Further, in order to smoothly change the direction of the wire F, a tunnel H is provided in this embodiment.

FIG. 8 shows an example of an embodiment of the present invention in which not only the front cuff and rear cuff can be closed, but also the counter E can be tightened at the same time, and the trigger 6 is used as a method for freely fixing the stopper pin 7. .

Furthermore, as shown in FIG. 10, the movable body 15 is mounted on the screw 16 so that the movable body 15 moves on the lever 1, and by rotating the knob 17 coupled to the screw 16, the movable body 15 is moved. The wire G fixed to the movable body 15 moves along with the movement on the screw 16, so that the tightening strength can be adjusted. As another method, although not shown, another trigger other than the trigger shown in FIG. 4 may be provided as a movable body 15 on the lever 1, and the wire G may be connected to this to adjust the tightening strength. It is also possible to do so. of course,
As long as the movable body 15 on the lever 1 can be moved, these methods are not critical.

Further, a tunnel H is provided to allow the wire F to change direction smoothly, and a pulley is also provided in the hole J to allow the wire G to move smoothly.

(Effect of the invention) When using this invention device, the wire F for closing the front cuff and the rear cuff is connected to the lever 1, so closing the front cuff and the rear cuff is as simple as pushing down the lever 1. It can be done with simple movements. Furthermore, the lever 1 has a wire F that closes the front cuff and the rear cuff,
It is also possible to tighten the counter E and connect the wire G for fixing the foot to the shoe, so in this case, the counter should be tightened and the foot to the shoe fixed at the same time as the front cuff and rear cuff are closed. These can all be done at the same time with the simple action of tilting the lever 1.

Furthermore, the wire F for closing the front cuff and the rear cuff is connected to the arm 4 and the slit member 3.
The other end of the arm 4 moves within the slit 20 on the lower surface of the lever 1, and its movement is suppressed by the stopper pin 7, so if the stopper pin 7 is moved, , the shaft attachment portion 21 of the arm 4 to the slit 20 moves in the direction of the base 2 to a position where movement is suppressed by the stopper pin 7. The shaft attachment part 32 between the arm 4 and the slit member 3, to which the wire F is fixed, also moves within the slit 31 at the same time, but as it approaches the direction of the base 2, the tension on the wire F becomes weaker, and the tension between the front cuff and rear cuff becomes weaker. The closing strength becomes weaker. Therefore, simply by moving the stopper pin 7, the closing strength of the front cuff and rear cuff can be adjusted. The stopper pin 7 can be fixed at any position within the slit 9 by attaching it to the trigger or tightening it with a nut.

In addition, the opening/closing angle of the front cuff and the rear cuff becomes the maximum at the position where the shaft attachment part 32 of the arm 4 and the slit member 3 is closest to the base 2; The shaft attachment part 21 with the slit 20 on the lower surface of the lever 1, which is the attachment part, is
Since it moves in the direction away from the base 2 which is not regulated by the stopper pin 7, the movement of the wire F is regulated no matter how the stopper pin 7 is moved in order to adjust the strength of closing the front cuff and the rear cuff. Fixed part with the slit member 3 (also a shaft-attached part between the arm 4 and the slit member 3) 32
can always move within the slit 31 to the position closest to the base 2. Therefore, it is possible to always maintain a constant opening/closing angle of the rear cuff when inserting the foot.

Next, wire G is used to pull the counter between the shell on the top of the instep and the inner boot.
is fixed to a movable body 15 that moves on the lever 1, so the tightening strength of the wire G can be adjusted by moving the movable body 15. The moving body 15 is moved on a screw or by using a trigger, etc.
It is possible to move it.

The closing strength of the front cuff and rear cuff and the tightening strength of the counter are determined by the stopper pin 7 and the moving body 15.
Once the lever is fixed at the desired strength position, the same strength will always be obtained even if the lever 1 is raised or pushed down to insert the foot into the shoe.

Therefore, using this device, the front cuff and rear cuff can be closed with a single action of one lever, and at the same time, the counter provided between the shell on the upper surface of the instep and the inner boot can be pulled. It also became possible. Furthermore, it is possible to fine-tune the closing strength of the front and rear cuffs and the tightening strength of the instep, so there are fewer movements when putting on the ski boots, making them easy to use even for beginners, women, and children. We can provide ski shoes.
