Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device for a snowboard, and more particularly to a high-back portion having a means which is suitable for use of so-called normal boots and which can be easily attached and detached and easily adjusted to the size of the boot. The present invention relates to a binding capable of adjusting the angle of the lens.

[0002]

2. Description of the Related Art Although snowboards have a relatively new history, various binding devices have been provided for them, but most of the binding devices that have been improved in the past are of the type using special boots. . Therefore, the binding mechanism is complicated, and the boot itself is subjected to special processing or has a special function so that these functions are combined to improve various functions of the binding.

[0003] On the other hand, despite the extremely large population of snowboarders using soft boots, ie, normal boots, they are excellent in convenience, especially in applicability to different boot sizes, and in simplicity of operation when attaching and detaching. In fact, a sufficient number of binding devices have not yet been devised.

When the problems in the prior art, including the conventionally known type shown in FIG. 22, are examined, the following points become clear. FIG. 22 shows a right foot binding device 60 in which, for example, a right foot boot (normal boot) can be freely attached and detached in a pair of left and right binding devices fixed to the snowboard body by screws.
Since the left and right bindings are generally configured to be symmetrical to each other, the right foot binding will be described in the specification of the present invention, and will be simply referred to as (snowboard) binding. .

[0005] A base plate 61 which is integrally provided on a board surface of a snowboard (not shown) or which can be fixedly fastened by screws to a fixed portion fixed separately, is provided with a fixing means 80 and a fixing means 80 at substantially the center thereof. Left and right side frame portions 62, 62 integrally formed in a right and left standing shape
And a heel cup member 70 for boots whose legs 71, 71 are fitted into grooves 63, 63 provided in each of the side frame portions 62 and are slidable in the front-rear direction.

The heel cup member 70 has, on the legs 71, 71, locking members 73, 73 for detachably fixing a rear strap ST1 for fixing an ankle portion of a boot. . The front strap ST2 for fastening the front of the boot is fixed to the base plate 6.
Using a plurality of bolt holes 64 drilled at the front ends of the left and right frame portions 62, 62, the degree of tightening is adjusted according to the boot to be used by changing the locking position and adjusting the strap.

On the other hand, means corresponding to the size of the boot include bolt holes formed in both legs 71, 71 of the heel cup member 70, and the leg members 71, 71.
The leg members 71, and thus the heel cup member 70, are slid and fixed in the front-rear direction by the bolt holes 65 provided in the side frame portions 62, , The corresponding structure. The rear of the heel cup member 70 is a so-called high back 74 extending upward.

By the way, in such a conventionally known snowboard binding, when the snowboarder wears the snowboard while wearing boots, for example, the rear strap ST1 of the binding is fixed to the locking members 73 at both ends locking metal fittings. Then, after moving the heel cup member 70 to a position suitable for the size of the boot, the bolts and nuts 66 are used to fix the side frames 62, 62 and the legs 71, 71. Thereafter, the strap ST1 is adjusted in a usual manner to tighten and fix the ankle portion of the boot.

Further, as shown in the figure, the toe portion of the boot has a bolt nut 6
7, the front strap ST2 is moved and fixed, and the normal fastening and fixing is performed in the same manner as the strap ST1. In addition, the binding 60 itself is provided at a substantially central portion of the base plate 61 by using a fixing means 80 to fix an arbitrary fixing part (not shown) of the snowboard body.
When the left and right binding positions or angles are adjusted, the bolt holes 83 at an arbitrary position are selected and tightened. However, in such a type of binding, the angle of the heel cup member 70 is unchanged.

Further, although not shown, in other types of bindings, a similar heel cup member is rotatable at a support portion provided on both side frame members, and a step-down bar integrally provided at a lower end of the heel cup member. Linked with
In some cases, the high-back portion of the heel cup member is tilted in the front-rear direction to easily attach and detach the boot. However, in such a type of binding, the support portion of the rotatable heel cup member is fixed, and the heel cup portion corresponding to the size of the boot is not moved. There was a disadvantage of poor adaptability.

[0011]

In the above-mentioned conventional snowboard binding for normal boots, only the heel cup member is moved or adjusted in accordance with the size of the boot, or the supporting portion of the heel cup member is There is only a so-called step-in type binding in which only the operation of rotating the boot is linked to the stepping-in operation of the boot, and the operation of attaching and detaching the boot is inconvenient.

According to the present invention, such a disadvantage is solved, the relative positions of the front and rear straps and the heel cup can be changed relatively easily in accordance with the size of the boot, and the relative position between the strap and the bottom of the heel cup is interlocked. The aim is to obtain a perfect step-in type snowboard binding by opening and closing both straps. Also, the heel cup has a high back part,
By making the coupling angle variable between this and the heel cup member, it can be easily adapted to various shapes of soft boots (normal boots) and their various dimensions, and its stability and ease of attachment and detachment are provided. It is intended to obtain a snowboard binding with a significantly improved.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The overall structure of one embodiment according to the present invention will be described with reference to FIGS. Details of each component will be described with reference to FIGS. FIG. 1 is an overall perspective view of a snowboard binding 10 according to the present invention, in which a fixing plate 59 (not shown in detail) is separately provided on a fixing plate provided on the surface of a snowboard (not shown).
(See FIG. 2), the base plate 11 to which the mounting fixed angle, that is, the direction of the boot can be adjusted freely.
have.

Reference numerals 12 and 13 denote an inner bracket and an outer bracket which are formed integrally with or fixed to the base plate 11, respectively.
As shown in the drawing, lower ends of the base plates 11 are fixed to the rear side surfaces of the base plate 11 by integral molding or fixing, respectively, and near the upper ends thereof, shafts for supporting a heel cup member 21 described later are provided. Holes are drilled.

Also, on both front sides of the base plate 11,
A front bracket 14 is fixed on the inside, and a strap support 15 is fixed on the outside by integral molding or fixing. Each of the brackets and the support has a different shape and size, but the inner bracket 12 and the outer bracket 13 have substantially the same height.

FIG. 2 is a plan view of the binding 10 of the present invention. The relationship between the positions of the brackets 12, 13, 14 and the strap support 15 with respect to the base plate 11 and the heel cup member 21 is clear. Further, each bracket, arm A and rear link 1 described later in detail.
6, the relationship between the front link 17, and the strap locking lever 18 is also clearly shown.

As is particularly clear from FIGS. 2, 3 and 5, the arm A, which is one of the characteristic components of the present invention, is rotatably supported by the inner bracket 12 and the front bracket 14, respectively. The arm A is not only movable substantially vertically in the vertical direction with respect to the base plate 11, but also the rear part of the arm A is largely moved upward. It is a structure that can be moved.

That is, the arm A has two shaft holes at its center, and one end of the arm A is

What is important here is that the operation thereof will be described in detail later. Since the arm A is rotatably supported by the axis P4 of the rear link 16, the rear link 16 is pivoted about the axis P2. When the pivotal movement is large, the shaft P4 is largely lifted upward, and as a result, the rear end of the arm A is moved very largely in the opening direction.

The rear link 16 and the front link 17 are preferably connected to the inner bracket 12, as shown in FIGS.
It is extremely desirable in appearance to provide the front bracket 14 and the arm A so as to be stored in a slit or a cutout provided in the thickness of the arm A or a side end thereof.

However, it is possible to adjustably connect the connection position in the connection axis direction. That is, the hexagonal cylinder shaft fixed non-rotatably to the hexagonal shaft holes provided in the rear link 16 and the strap locking lever 18 and a number of hexagonal bearing recesses for receiving the ends thereof are selectively engaged. Thereby, the position can be adjusted so as not to rotate relatively.

Next, details of each part will be described with reference to FIGS. The back portion generally indicated by the reference numeral 20 is generally constituted by a heel cup member 21, a high back member 50, and a high back piece 30. 2, 7, 8, and 9, the heel cup member 21 is formed to have a substantially U-shape in plan view, and has a slightly curved back portion 22, and a side plate portion extending forward from both left and right sides. 23 and 25 are protruded, and the locking arms 24 and 26 are integrally formed in a state in which the locking arms 24 and 26 hang down obliquely forward and downward from near the front ends of the respective side plates 23 and 25. The degree of inclination of each of the locking arms 24 and 26 with respect to the base plate 11 is for moving the entire heel cup in the front-rear direction and the vertical direction simultaneously with the size of the boot.
The degree is appropriate.

As is apparent from FIGS. 8 and 9, the heel cup member 21 has a heel cup 27 integrally formed below the rear surface 22 thereof. Each of the left and right locking arms 24 and 26 has a shaft hole, such as a plurality of bolt insertion holes, which is one of the characteristic configurations of the present invention (described later) and is linearly arranged as shown in the drawing. H1-H

At the center of the upper portion of the high-back piece 30, although the detailed structure is omitted, as shown in FIG. 6, a mounting hole 33 for mounting the horizontal tilt adjustment fixing means 55 for the high-back member 50 is provided. I have. The high-back member 50 of the present invention enables two types of high-back positions that can swing in a center fixed state and a left and right inclined state by changing the mounting position of the fixing means. At a lower central portion of the high back piece 30, a pair of locking pieces 34, 34 are formed to protrude integrally in a side view arc shape.
The pair of arc-shaped locking pieces 34, 34 are divided by a concave notch 35 whose middle part is opened downward, and a large number of saw tooth strips 36 are formed on the inwardly curved surfaces of both arc-shaped locking pieces 34, 34. It is engraved.

FIGS. 15 and 16 show the plane and side shapes of the tightening lever 44, respectively.
It has a head 45 having H9, and a cam surface portion 46 is formed on the outer periphery of the head. Such a tightening lever 4
4 is engaged with the end of the pulling rod 43 at the head notch 47, and is rotatably connected to the shaft hole H8 and the shaft holes H9, H9 by inserting a pin or the like. With such a structure, when the tightening lever 44 is turned up and down, the cam surfaces 46 of the heads 45 and 45 come into contact with the back surface of the heel cup member 21 to move the pulling rod 43 in the front-rear direction.

When the high back piece 30 is attached to the heel cup member 21, the arc-shaped locking pieces 34, 34 of the high back piece 30 are housed in the recesses 29 of the back portion 22, as is apparent from FIGS. Then, the pulling rod 43 of the locking piece 41 penetrates through the central recessed portion 35 and the square hole 28 provided at the center of the rear portion 22, and then the head of the tightening lever 44 crosses over the shaft hole H <b> 8. Shaft holes H9, H9 provided in the portions 45, 45
And then rotatably connect with an arbitrary pin or the like.

The back tilt angle adjusting member 40 having the above-described structure is used.
As shown in FIG. 6, the arc-shaped locking pieces 34, 34 below the back piece 30 are rotated by the rotation of the cam surface 46 of the tightening lever 44 so that the rear portion 22 of the heel cup member 21 can be used.
The relative angle can be firmly fixed and maintained by engaging the two sawtooth strips with each other in an arbitrary inclined state of the high back piece 30.

FIG. 17 shows a cross-sectional shape of the high-back member 50. The middle part of the high-back member is given an appropriate warp in the vertical direction according to the shape of the boot from the ankle part to the upper part, and it also curves forward in the width direction almost according to the outer shape of the boot. I have. An opening 51 through which the left-right tilt adjustment and fixing means 55 for the high back piece 30 is inserted is provided slightly in the middle thereof. The opening 51 has a vertically long oval shape having parallel portions on the left and right sides, and a hexagonal fixing column body of the fixing means is engaged in the opening of the parallel portion and can be fixed at an arbitrary vertical position. Further, the high-back member 50 can be tilted to the left and right by an arbitrary set amount with respect to the high-back piece 30 as necessary. The detailed description of the tilt adjustment fixing means 55 is omitted.

FIG. 18 is a side view of the rear link 16 shown in FIGS. The part of the rear link 16 pivotally supported by the inner bracket 12 at the upper end thereof is one of the characteristic features of the present invention. For example, a regular hexagonal shaft hole Hm is formed in the upper end. This regular hexagonal shaft hole Hm
Correspond to the hexagonal bearing recesses G1 to G5 provided on the left and right locking arms 24, 26 of the heel cup member 21 via a hexagonal cylinder shaft c described later, and correspond to any of these selected hexagonal recesses. This is a means for integrally connecting the rear link 16 and the heel cup member 21 by connecting them with a hexagonal axis. The rear link 16 further includes a stopper shaft hole H9 for preventing rotation of the link 16 about the axis P1 and a connection point P4 between the arm A and the stopper shaft hole H9.
Is formed. In addition, a stopper knob 56 is provided at a position facing the inner bracket 12 corresponding to the stopper shaft hole H9.

Although the details of the structure of the stopper knob 56 are omitted, for example, the stopper knob 56 can be constituted by a shaft having a fixing screw portion at the tip or a pin body constantly urged in a fitting direction by a spring or the like. Then, the shaft portion of the stopper knob 56 is inserted in a state where the stopper shaft hole H9 is aligned with the shaft hole or the like provided in the inner bracket 12, thereby making the inner bracket 12 and the rear link 16 unrotatable, Thereby, the fixed state of the binding is maintained. The structure of the stopper knob 56 is not characteristic in itself, but may be any means capable of securely and easily fixing or releasing the rear link 16 with respect to the inner bracket 12.

FIG. 19 is a plan view showing a state in which a hexagonal cylinder shaft c and cylindrical bodies a and b, which will be described later, are inserted through the hexagonal shaft hole Hm of the rear link 16, respectively. A long cylindrical body a and a slightly short cylindrical body b are respectively inserted into both protruding portions of the hexagonal cylinder shaft c fitted and fixed to the inside of the hexagonal cylinder shaft c. The hex cup shaft c is rotatably supported by a hole Hn, and the inner end of the hexagonal cylinder shaft c has a series of hexagonal bearing recesses G1 to G5 formed on the outer surface of the left locking arm 24 of the heel cup member 21. And is fixedly inserted into any one of them. In such a state, a fixing pin or bolt is appropriately inserted as a shaft P1 into a hollow portion inside the cylinder of the hexagonal cylinder shaft c, and the rear link 1
6 and the left locking arm 24 are not rotated, and the inner bracket 1 is not rotated.
Reference numeral 2 denotes a rotatably supported shaft (particularly, see FIGS. 2 and 3).

Here, the hexagonal cylinder shaft c, the long cylindrical body a and the somewhat short cylindrical body b will be further described. The outer diameter of the hexagonal cylindrical shaft c is inserted into the hexagonal shaft hole Hm of the rear link 16 and It has a size that allows it to rotate integrally without play, and fits into a hexagonal recess provided in the left and right locking arms 24 and 26 to rotate integrally with the arm members. The center of the hexagonal cylinder shaft c is a cylinder having a shaft hole as shown in FIG. Therefore, these cylindrical bodies a and b and the hexagonal cylinder shaft c
As shown in FIG. 2, the link 16 can be easily supported by the inner bracket 12 by passing a fixing pin or a bolt corresponding to the axis P1 into the center hole of the hexagonal cylinder.

FIGS. 20A and 20B show the structure of the locking lever 18 for fixing the rear strap ST1 also shown in FIGS. 2 and 5, which is substantially L-shaped when viewed from the side. A hexagonal shaft hole Hm similar to the rear link 16 is formed at the rear end of the stop lever 18, and the front end has a bulged portion provided with a normal shaft hole Hn. By attaching an appropriate locking means to the shaft hole Hn at the front end, a locking portion such as an adjusting locking hole provided at the other end portion 2 of the rear strap ST1 can be fixed.

FIGS. 21A and 21B show a hexagonal cylinder shaft c, a long cylindrical body a, and a slightly short cylindrical body b mounted in the hexagonal shaft hole Hm of the locking lever 18 shown in FIG. It shows a side view and a plan view of the state. As shown in FIG.
On both sides of the hexagonal cylinder shaft c which is inserted through the hexagonal shaft hole Hm at the rear end of the locking lever 18 in a non-rotatable manner, a slightly shorter cylindrical body b is fitted inside the hexagonal cylinder shaft c, and the hexagonal cylinder shaft c protruding from this. In the same manner as in the case of the rear link 16, any one of a series of hexagonal bearing concave portions G1 to G5 (corresponding to the arm portion 24) provided outside the right locking arm portion 26 of the heel cup member 21. ).

On the other hand, as shown in FIG. 2 and FIG.
It is inserted into and supported by two shaft holes Hn, and an appropriate fixing pin or bolt is inserted into the center hole of the hexagonal cylinder shaft c in the same manner as in the case of the link 16, and the right locking arm 26 of the heel cup member 21 is inserted.
And the outer side of the outer bracket 13 is fastened so that the locking lever 18 and the locking arm 26 of the heel cup member are non-rotatably supported and the outer bracket 13 is rotatably supported. is there. Thus, the inner bracket 1
2 and axes P1, P2 on the outer bracket 13,
The locking arms 24, 26 and thus the heel cup member 21 are capable of rotating at least 40 degrees from the tightened position to the open position.

As is clear from FIGS. 1, 3 and 5, one end of the front strap ST2 and one end of the rear strap ST1 are both buried and fixed at appropriate positions in front and rear of the arm A.
The arm A can be moved between the open or fixed positions according to the vertical movement or other swing of the arm A. Also, the front strap ST
The other end of 2 is a fixed bracket 1 on the outside front of the base plate.
5, one of a plurality of shaft holes (see FIG. 5)
It is selectively locked and fixed.

Further, the other end of the rear strap ST1 is locked and fixed to any locking means attached to the front end shaft hole Hn of the locking lever 18, and the locking and locking is performed according to the tilting of the locking lever 18. The part moves up and down greatly. Needless to say, the tilting of the locking lever 18 and the vertical movement of the preliminary locking portion coincide with the movement of the link 16.
Therefore, in the present invention, as described above, in particular, the rear strap ST1 portion is largely opened or closed in the locking position according to the front-back tilting of the heel cup member or the high back portion.

The operation of the binding of the present invention will be described. First, the engagement between the inner bracket 12 and the rear link 16 is released at the stopper knob 56 and the back portion 20 having the high back portion is tilted rearward. , The locking arms 24, 2 of the heel cup member 21.
6 rotates upward about the shaft portions P1 and P2. Along with this, the rear link 1 is locked and fixed so that it cannot rotate relatively.
6 and the locking lever 18 rotate upward, so that the shaft P4 of the arm A and the strap locking shaft Hn, which are pivotally supported at the ends thereof, greatly expand and move upward, respectively. The rear strap ST1 fixed to Hn and the rear end of the arm A is largely opened. Since the front end of the arm A also moves upward, the front strap ST2 fixed here is released by an appropriate amount.

In this state, when the snowboarder inserts the boot between the back portion tilted backward and the rear strap ST1 with a large opening upward and steps down the heel cup 27 with the heel of the boot, Cup member 21
In contrast to the above, the high back portion is inclined forward and abuts along the rear side of the boot, and at the same time, the rear link 16 and the arm A integrally connected, and the strap locking lever 18 are turned or lowered downward. In conjunction with this, the rear strap ST1 finally descends to the boot fixing position and is tightened. At the same time, the front of the arm A is simultaneously lowered by the action of the links 16 and 17, and is settled in the tightened position in FIG.

In this state, the stopper shaft hole H9 of the rear link 16 is connected to the shaft hole Hn of the inner bracket 12.
The boots are easily and securely fixed to the strap by operating the stopper knob 56 or automatically locking them with a spring or the like, since they match the position (not shown in the drawing). The front and rear straps ST1, ST
Of course, 2 has its own adjusting means, so that its clamping force can be adjusted if necessary.

If the sizes of the boots are different, it is preferable to operate the pins or bolts at the shaft portions P1 and P2 before the above operation so that the rear link 16 and the hexagonal cylinder shaft of the locking lever 18 are engaged. By changing the positions of the corresponding hexagonal shaft recesses G1 to G5 in both the locking arms 24 and 26 of the heel cup member 21 to be changed, the relationship between the optimum back portion position and the strap position according to the size of the boot is changed. Will be selected.

[0047]

In the above-described binding of the present invention, when the heel cup portion of the high back is inclined rearward, the rear link 16 and the locking lever 1 are interlocked with this.
8 rotate integrally, and the straps connected directly to them or via the arms A rise significantly. Therefore, the boot can be easily stepped into the binding. Also, the heel cup member 21 and the rear link 16,
The rear link 16 and the inner bracket 12 are locked by the lock knob 56 only by adjusting the tightening position of the boot with the strap, heel cup, high back member, etc. in advance according to the size of the boot by the locking lever 18. The complete step-in type binding can be obtained only by performing the above operation. Furthermore, since the angle of the high back member can be adjusted very easily with respect to the heel cup member only by rotating the tightening lever 44, the combination of the arm A and the strap allows easy operation of various types of soft boots. In this case, an appropriate tightening force can be applied.
