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. And an angle-adjustable and swingable binding.

[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. 23, are examined, the following points become clear. FIG. 23 shows a right foot binding device 60 in which a pair of right and left boots (normal boots) can be detachably fixed, for example, in a pair of left and right binding devices fixed to the snowboard body by screws.
In addition, since the left and right bindings are generally configured to be symmetrical to each other, in the specification of the present invention, the right foot binding will be described below, 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.

[0006] The heel cup member 70 has a locking member 7 for detachably fixing a rear strap ST1 for fixing an ankle portion of a boot to the legs 71, 71 thereof.
3, 73. The front strap ST2 for tightening and fixing the front of the boot is provided on the base plate 61.
By using a plurality of bolt holes 64 drilled at the front ends of the left and right side 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, as means corresponding to the size of the boot, there are bolt holes formed in both legs 71, 71 of the heel cup member 70, and the above-mentioned legs 71, 71 are fitted and slid. A plurality of bolt holes 65 provided in the side frame portions 62, 62 allow the leg portion 71, and thus the heel cup member 70, to be slid and fixed in the front-rear direction with respect to the base plate 61, thereby providing a 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 by ordinary means 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 immobilized. In addition, there is only a so-called step-in type binding in which only the operation of rotating this is linked with the stepping-in operation of the boot, and not only is the operation of detaching and fixing the boot inconvenient, but also the binding of the heel cup member is fixed. It is immovable to the left and right in the closed state, and the high-back portion does not allow the boot to tilt. Therefore, the snowboarder is restricted from free movement at his ankle,
Various maneuvering operations were difficult. In addition, since the fixing position of the boots with respect to the snowboard has a considerable interval, the legs generally have an inverted V shape, and the left and right boots are naturally inclined inward.

The present invention solves such a problem and selectively and easily forms a form in which the highback portion is restrained in accordance with various maneuvering forms of the snowboard and a state in which the snowboard can freely tilt within a specified range. The purpose of the present invention is to obtain a snowboard binding that can be switched by a simple operation. In addition, a heel cup member having a high-back portion can be easily adapted to various shapes of soft boots (normal boots) and various sizes thereof,
An object of the present invention is to provide a snowboard binding whose stability and ease of attachment / detachment are significantly improved.

[0013]

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.

2, 3, and 5, the arm A is connected by a rear link 16 and a front link 17 rotatably supported by the inner bracket 12 and the front bracket 14, respectively. As a result, the arm A can move not only substantially vertically in the vertical direction with respect to the base plate 11, but also can move a rear part of the arm A largely upward.

That is, the arm A has two shaft holes at its center, and one end of the arm A is
1 is connected to the other end of the rear link 16 pivotally supported by the shaft P4, and one end of the front bracket 14 is connected to the other end of the front link 17 pivotally supported by the shaft P3 by a shaft P5. , 17 are pivoted about the respective axes P1, P3, thereby being moved upward in accordance with the trajectories of the axes P4, P5 which are the respective link tips (see FIG. 5).

What is important here is that the operation thereof will be described in detail later. Since the arm A is rotatably supported on the axis P4 of the rear link 16, the rear link 16 is pivoted about the axis P1. When the shaft P4 is largely rotated, 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. Also, the rear link 16
Preferably, the front link 17 is provided so as to be stored in a slit or notch provided in the thickness of the inner bracket 12, the front bracket 14, and the arm A or at the side end thereof, as shown in FIGS. However, it is highly desirable in appearance.

1, P2, it is rotatably supported, and the left and right front of the heel cup member 21 of the back portion 20 and the respective rear portions of the rear link 16 and the strap locking lever 18 do not relatively rotate as described later. Are connected to the rear link 16 and the strap locking lever 18 so that their connection positions can be adjusted in the member 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, the details of each back portion will be described with reference to FIGS. The back part generally indicated by the reference numeral 20 is generally constituted by a heel cup member 21, a high back member 41, 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,
25 protrudes from the vicinity of the front end of each side plate portion 23, 25, and the locking arm portions 24, 26 are integrally formed in a state of hanging downward obliquely forward. 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 shown in 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
and hexagonal bearing recesses G1 to Gn, which are concentric with the respective shaft holes and reach the intermediate positions of the members on the outer surfaces of the locking arms 24 and 26, respectively. Have been. Here, the number of bores of the shaft hole Hn and the hexagonal bearing recess Gn is not particularly limited. For example, six bores may be provided at regular intervals, and the center distance of each insertion hole may be 5 to 8 mm. In such a case, the heel cup member 21
For example, it can move about 3-4 cm.

The square hole 28 provided above the back surface of the heel cup member 21 is provided with the heel cup member 2 as described later.
The back inclination angle adjusting member L0 is used to fix the high back member 41 to the heel cup member 21 while adjusting the relative angle of the high back member 41 with respect to the front-rear direction using the high back piece 30 inserted into the concave portion above the first member. It is a pull rod insertion hole for the.

FIGS. 10 to 12 show the plane, back and side cross sections of the high back piece 30 in the back portion 20 as shown in FIGS. 4 and 6, respectively. The elbow rods 31, 31 integrally formed so as to protrude from both lower ends of the high back piece 30, as shown in FIGS. 6 and 9,
A pair of shafts housed in recesses 29, 29 provided on the front surface of the back portion 22 of the heel cup member 21, and formed on the shaft holes H 7, H 7 of the respective elbow rods 31, 31 and both sides of the heel cup member 21. It is rotatably supported by a suitable (not shown) support bolt or the like via a hole H6 (see FIG. 9).

At the center of the upper portion of the high back piece 30, a tilt adjustment fixing means 50 for the right and left direction for the high back member 41, which is a characteristic structure of the present invention (which will be described in detail later), is attached as shown in FIG. An adjustment engagement hole 39 is provided. And the high back member 41 in the present invention is
By changing the mounting position (angle) of the fixing means, two types of high back positions capable of swinging in the center fixed state and the left and right inclined state are made possible.

As is apparent from FIG.
0, a pair of locking pieces 34 in an arc shape in a side view,
34 are protruded integrally. The pair of arc-shaped locking pieces 3
4 and 34 are divided by a concave notch 35 whose middle part is opened downward (see FIG. 11).
A number of serrations 36 are engraved on the inwardly curved surfaces 4 and 34.

As is particularly clear from FIGS. 4 and 6, the high back piece 30 is provided with a shaft hole H in both elbow rods 31, 31.
7, H7, the side plate portion 23 of the heel cup member 21,
25, and a relative angle in the front-rear direction with respect to the heel cup member by a back tilt angle adjusting member L0 described later at the pair of arc-shaped locking pieces 34, 34, that is, the back tilt. The corners can be adjustably fixed. Here, it is desirable that the heel cup member 21 be rotatable at least about 60 degrees by the pivot holes of the shaft holes H7, H7 and the two elbow rods 31, 31.

FIGS. 13 and 14 show components of the back tilt angle adjusting member L0. FIG. 13 shows a locking piece L1 which engages with the arcuate locking piece 34 of the high back piece 30 shown in FIGS. 6 and 12, and a number of saw teeth L2 engraved on the outwardly curved surface thereof. The adjusting member L0 is composed of a pulling rod L3 connected to the center of the locking piece L1, and has a shaft hole H8 at an end of the pulling rod L3.

The tightening lever L4 whose side shape is shown in FIG. 14 has a head L5 having a shaft hole H9, and a cam surface C is formed on the outer periphery of the head. Such a tightening lever L4 is connected to the above-described pulling rod L3 at the notch of the head.
And a pin or the like is inserted into the shaft hole H8 and the shaft hole H9 to be rotatably connected. With such a structure, when the tightening lever L4 is turned up and down, the cam surface C of the head comes into contact with the back surface of the heel cup member 21 to move the pulling rod 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, it passes through the rod L3 of the inclination angle adjusting member L0 through the central recessed portion 35 and the square hole 28 provided at the center of the back surface portion 22, and then straddles the shaft hole H8 of the tightening lever L4. After the shaft holes H9 provided in the head L5 are aligned with each other, the shaft holes H9 are rotatably connected with an arbitrary pin or the like.

The back tilt angle adjusting member L0 having such a configuration is provided.
As shown in FIG. 6, the arc-shaped locking pieces 34, 34 below the back piece 30 are pressed against the back portion 22 of the heel cup member 21 by the rotation of the cam surface C of the tightening lever L4. By engaging the two saw teeth with each other in any inclined state of the high back piece 30,
The relative angle between 0 and the heel cup member 21 can be firmly maintained.

The most characteristic structure of the present invention will be described with reference to FIGS. FIG. 15 shows a front view (A) and a central longitudinal sectional view (B) of the high-back member 41. The concave portion 4 is formed at the center of the high-back member 41 from the front.
Preferably, the recess is a recess having side surfaces parallel to at least the left and right sides thereof, and a regular hexagonal corner is preferably formed at the upper and lower ends thereof. Reference numeral 43
Indicates a vertically elongated opening formed in the bottom surface of the concave portion 42. As will be described later, the adjusting member of the high back piece 30 is fixed by the separately provided fixing means 50 through the vertically elongated opening 43 and the concave portion 42. The high-back member 41 is fixed or swingably locked in the hole 39.

FIG. 16 shows a high back member 41 with a reference numeral 50.
6 shows the front and side surfaces of the engagement piece 51 among the fixing means (see FIG. 6) shown more comprehensively. The outer shape of the board part 52 of the engagement piece 51 is formed in a regular hexagon,
At the center thereof, there is a columnar shaft 53, and the shaft 53
Has an engaging portion formed of a central cylindrical portion Vs and a lateral fan-shaped portion Vt on the projecting portion 54. At the center of the central cylindrical portion Vs, a screw hole 55 for fixing is provided.

FIG. 17 is a front view and a side view of the fastening piece 56 of the fixing means indicated by the reference numeral 50. The fastening piece 56 is fitted into the adjusting engagement hole 39 in FIG. And a knob portion 58 and a screw rod 59. Then, as is apparent from FIG.
1 from the side of the concave portion 42, the tightening pieces 56 are respectively fitted from the screw rods 59 of the high back piece 30, and the screw holes 55 are formed.
And the screw rod 59 to fasten and fix the high back piece 30. Accordingly, the width of the concave portion 42 shown in FIG. 15 substantially matches the width of the parallel ridge line portion of the hexagonal substrate portion 52 of the engagement piece 51, and the width of the vertically long opening 43 is also substantially the same as the diameter of the shaft portion 53.

FIG. 18A shows a state in which the recess 42 and the vertically long opening 43 of the high-back member 41 and the adjusting engagement hole 39 of the high-back piece 30 are inserted into the screw hole 55 and the screw of the tightening piece 56 in FIG. The engagement piece 51 fixed to the high back piece by the rod 59, particularly the hexagonal shape of the substrate 52, the cylindrical portion Vs and the fan-shaped portion Vt of the protruding portion 54 (see black engraved portion) are shown. In addition, FIG.
, The adjustment engagement hole 3 in the high back piece 30
9 shows a central circular hole W, a top locking hole X, and left and right locking holes Y and Z.

The fan-shaped portion Vt of the projecting portion 54 of the engagement piece 51
Are the top locking holes X or the right and left locking holes Y shown in FIG.
Z, the pair of ridge lines from any of the hexagonal substrates 52 at that time engage with the left and right parallel side surfaces of the concave portion 42 in the high back member 41,
The high back member 41 can swing in a state in which the high back member 41 is inclined to the vertical position or to the left or right with respect to the high back piece 30.

FIGS. 19 (A) to 19 (C) show the engagement piece 51 in FIG. 18 described above, that is, its fan-shaped portion Vt and the engagement holes X to Z in the adjustment engagement hole 39 of the high back piece 30 with which it is engaged. Thus, the function of the high-back member 41, which is a feature of the present invention, in the fixed or inclined swing state becomes clear.

More specifically, FIG. 7A shows the relationship between the engagement piece 51 and the adjustment engagement hole 39 when the high-back member 41 is fixed in a vertical state. That is, the shape of the upper locking hole X in the adjustment engagement hole 39 is
Since the shape of the fan-shaped portion Vt of the engagement piece 51 is substantially the same, when the fan-shaped portion Vt is inserted into the locking hole X in the state shown in FIG. The engagement piece 51 becomes rotatable. Accordingly, the concave portion 42 of the high-back member 41 is fixed by the left and right vertical ridges of the hexagonal substrate portion 52 in this state, and the high-back member 41 itself cannot swing with respect to the high-back piece 30 and thus the binding. However, the recess 4 of the high-back member 41
Since both the second and vertical openings 43 extend vertically, it goes without saying that the high-back member 41 can be moved and adjusted in the vertical direction.

FIG. 7B shows a state in which the fan-shaped portion Vt is inserted into the locking hole Y in the same manner as described above. In this state, temporarily
When one side of the fan-shaped portion Vt contacts the lower side Yd of the locking hole Y shown in FIG. 18 (B), the position becomes exactly as shown in FIG. 18 (B), and the pair of ridge lines with the hexagonal substrate 52 are vertical as shown. Can be set to a position parallel to. Further, when the fan-shaped portion Vt rotates clockwise about the central cylindrical portion Vs from this state, the other side rotates to the Lu line, which is the upper surface of the locking hole Y, and stops. That is, if the size (sector-shaped angle) of the locking hole Y is appropriately selected, the fan-shaped portion Vt can rotate in the range from the line Ld to the upper surface line Lu. Therefore, in this state, the high-back member 41 defined by the two parallel ridges of the hexagonal substrate 52 can swing clockwise (right side in the figure) from the vertical position within an appropriate angle range (for example, the angle Ld-Lu). It turns out that it is set to.

Similarly, in FIG.
"t" indicates a state of being inserted into the locking hole Z. In this case, the fan-shaped portion Vt rotates counterclockwise from Rd to the position of the line Ru in the drawing in the opposite direction to the above clockwise direction. As a result, the high-back member 41 is consequently moved from the vertical position in a counterclockwise direction (left side in the drawing) within an appropriate angle range (for example, the
It can be seen that d-Ru) is set so as to be swingable. The size (sector angle) of the locking holes Y and Z is arbitrarily designed according to the required swing angle.

Next, the fixing and swing adjusting operations of the high-back member, which is a characteristic configuration of the present invention, will be described. For snowboards, the direction in which the boots are fixed relative to the board is generally determined in relation to the preferences of the snowboarder or his personal dominant foot. In addition, since there is a considerable interval between the left and right boot fixing positions, it is often necessary to incline (tilt the boot) or swing the foot during operation. On the other hand, according to the above configuration of the present invention, it is possible to fix the high back member to the high back piece together with the left and right bindings and to be swingable right or left from the vertical position to the high back piece.

That is, when the engaging piece 51 is inserted into the adjusting engagement hole 39 to connect the high-back member 41 and the high-back piece 30, the engaging hole X of the adjusting engaging hole 39 is formed.
When the fan-shaped portion Vt of the projecting portion 54 is inserted into the high-back member 41 and the high-back piece 30, the hexagonal substrate 52 and the side surface of the concave portion 42 are integrally fixed. Also,
When the fan-shaped portion Vt is similarly inserted into the locking hole Y of the adjusting engagement hole 39, the boot (or the high back) can be freely swung to the right side as viewed from the rear side. When the fan-shaped portion Vt is similarly inserted into the stop hole Z, a boot (or high back) is similarly connected to the left side in rear view so as to be swingable by an arbitrary angle. Such a connecting operation can be performed very easily by attaching and detaching the tightening piece 56 to and from the engaging piece 51 by using the screw rod 59 thereof.

In the binding of the present invention having the back member as described above, the details of the binding mechanism will be described. FIGS. 20A and 20B are a side view and a plan view of the rear link 16 shown in FIGS. For example, a regular hexagonal shaft hole Hm is formed in a portion where the rear link 16 is pivotally supported at the upper end by the inner bracket 12. A long cylindrical body a and a slightly short cylindrical body b are respectively inserted into both protruding portions of a hexagonal cylinder shaft c fitted and fixed in the regular hexagonal shaft hole Hm, and the inner brackets are provided at the respective cylindrical bodies a and b on both sides thereof.

A stopper knob 90 (details of the structure is omitted) is provided at a position corresponding to the inner bracket 12 corresponding to.

Here, the hexagonal cylinder shaft c, the long cylindrical body a, and the slightly short cylindrical body b will be further described. The outer diameter of the hexagonal cylindrical shaft c is inserted through the hexagonal shaft hole Hm of the rear link 16 so that It has a size that allows it to rotate integrally without play, and fits into a hexagonal bearing recess provided in the left and right locking arms 24 and 26 to rotate integrally with the arm member. The center of the hexagonal cylinder shaft c is a cylinder having a shaft hole as shown in FIG. Accordingly, the link 16 having the cylindrical bodies a and b and the hexagonal cylinder axis c allows the fixing pin or bolt corresponding to the axis P1 to penetrate through the center hole of the hexagonal cylinder, as shown in FIG. Can be supported.

FIGS. 21A and 21B 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 appropriate locking means to the front end shaft hole Hn, a locking portion such as an adjusting locking hole provided at the other end of the rear strap ST1 can be fixed.

FIGS. 22A and 22B show a hexagonal cylinder shaft c, a long cylindrical body a, and a somewhat 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 Gn (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 arm 13 is fastened from the outer side of the outer bracket 13 so that the locking lever 18 and the locking arm 26 of the heel cup member are not pivoted, and the outer bracket 13 is pivotally 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

It is selectively locked and fixed.

Further, the other end of the rear strap ST1 is locked and fixed to any locking means mounted on the shaft hole Hn on the front end side of the locking lever 18, and the locking and locking is performed as the locking lever 18 tilts. The part moves up and down greatly. Needless to say, the tilting of the locking lever 18 and the vertical movement of the locking fixed 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 above-mentioned binding of the present invention will be described. First, when the engagement between the inner bracket 12 and the rear link 16 is released at the stopper knob 90 and the back portion 20 having the high back portion is tilted backward, , 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, the heel 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 shaft hole H9 for the stopper of the rear link 16 is aligned with the shaft hole Hn of the inner bracket 12.
The boots are easily and securely fixed to the strap by operating the stopper knob 90 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.

[0055]

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 90 simply by adjusting the tightening position of the boot with a strap, a heel cup, a high back member or the like in advance according to the size of the boot by the locking lever 18 in advance. The complete step-in type binding can be obtained only by performing the above operation. Further, 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.
A proper tightening force can be easily applied to various types of soft boots in combination with the interlocking operation between the boot and the strap.

According to the present invention, the high-back member of the binding can be fixed or swingably connected to an arbitrary position by an extremely simple operation, so that the boot can be freely fixed according to the player's preference. . Also, in combination with the other structure of the binding, a special effect is achieved in that the detachment of the boot itself can be extremely easily detached and fixed in any direction and position.
