Description

[Detailed explanation of the invention] In a ski that connects the ski and shoe mounting plate with a wire, the shoe mounting plate can be detached from the ski due to an impact such as a fall. The tension of the wire must be adjusted to maintain a constant position, but conventionally this adjustment is done at the part of the wire that is attached to the ski, making the adjustment extremely troublesome and difficult, especially for amateurs. It was hot.

The present invention is an attempt to improve the above-mentioned deficiencies of the conventional technology.A pair of guide rolls are supported on the shoe attachment plate, and a rotor that is rotated in one direction by a spring is attached to the shaft. A wire with both ends fixed to the shoe attachment plate locking part of the plate is stretched around the rotor so as to rotate in the opposite direction to the direction in which the wire is biased, and the wire is biased by a spring in a recess formed on the circumferential surface of the rotor. In a ski fitted with a pressing protrusion, the center part of a connecting piece, which has a pair of tension rolls pivotally supported at both ends, is pivoted behind the rotor of the shoe attachment plate, and a wire is inserted between the pair of tension rolls. In addition, the connecting piece is formed to be rotatable by an adjustment rod supported on the shoe mounting plate.

An embodiment of the present invention will be described with reference to the drawings. The locking devices 3 and 4, which are provided in front and behind the upper surface of the ski 1 and which secure both ends of the wire 2, have a shoe attachment plate 5.
The engaging tools 6 and 7 are removably engaged with each other, and the wire 2 is guided into the shoe mounting plate 5 from the engaging tools 6 and 7.

Further, a rotor 9 which pivotally supports a pair of guide rolls 8, 8 facing the upper surface is pivoted approximately at the center of the shoe mounting plate 5, and the rotor 9 is rotated counterclockwise by a spring 10 mounted on the inside thereof. The pair of guide rolls 8, 8 are provided with the wire 2 via tension rollers 11, 12, 13.
The rotor 9 is wound and stretched, and in particular, the stretching mode is
is formed to rotate in a direction opposite to the direction in which the spring is energized, that is, in a clockwise direction.

Further, an arc-shaped recess 14 is formed in the rear part of the circumferential surface of the rotor 9, and a spring 1 is provided in the recess 14.
The pressing protrusion 17 of the pressing tool 16 urged forward at 5 and 15 fits and locks the rotation of the rotor 9, and the pressing protrusion 17 is continuously inserted into one side of the recess 14 from the recess 14. A deep locking recess 18 is provided, and a rope locking protrusion 19 is integrally fixed to the upper surface of the pressing tool 16.

However, the tension rolls 11, 12, 1
3, the tension roll 11 is pivoted to the shoe mounting plate 5;
The wire 2 , which is wound around a pair of guide rolls 8 and 8, is connected to a pair of tension rolls 12 and 13. After passing through the gap, the shoes are guided by tension rolls 11 and stretched toward the rear of the shoe mounting plate 5.

Further, an elongated hole 25 at the tip of an operating rod 24 whose base end is supported by the shaft 22 of the shoe mounting plate 5 via an elongated hole 23 is fitted into the shaft support of the tension roll 13 of the connecting piece 21. A pin 29 of a sliding piece 28 fitted into a guide groove 27 of the shoe mounting plate 5 is fitted into a long hole 26 bored in the center of the shoe mounting plate 24 . An adjusting screw 30 rotatably supported on the side of the holder is screwed into the holder.

In addition, 31 in the figure is the base narrow diameter part 32 of the adjusting screw 30.
A retaining piece 32 fits into the springs 15, 15.
34 is a rotor position viewing window;
Reference numeral 35 denotes a stopper provided so as to be able to move in and out toward the rotor 9. When the wire 2 is removed from the ski 1, the stopper 35 engages with a notch 36 in the rotor 9 to prevent rotation of the rotor 9.

Since the embodiment of the present invention is constructed as described above, under normal conditions, the pressing protrusion 17 engages with the recess 14 of the rotor 9 as shown in FIG. The rotational force due to the tension of the spring 10 is balanced with the rotational force of the spring 10, but due to a fall or other impact, the springs 15, 15
If a force greater than the pressing locking force is applied, the wire 2
rotates the rotor 9 in the clockwise direction while extending, the pressing protrusion 17 is lifted from the recess 14 onto the circumferential surface of the rotor 9, and either of the engaging tools 6, 7 of the shoe attachment plate 5 is connected to the locking tool 3, 4 and the ski 1 can be removed from the shoe attachment plate 5.

However, when the tension of the wire 2 and the biasing force of the spring 10 change and the balance between the rotational force of the rotor 9 and the biasing rotational force of the spring 10 is lost and the pressing protrusion 17 no longer fits correctly into the recess 14, the adjustment is made. Rotate the screw rod 30, rotate the operating rod 24, and connect the connecting piece 21 to the pin 2.
Tension roll 12, which slides left and right around 0,
13 to tighten the tension of the wire 2 as shown in FIG. 3 or loosen it as shown in FIG. It is something to do.

The present invention is a ski in which a shoe attachment plate is attached to and connected to a ski board using the tension of a wire, in which a wire wound around a rotor is inserted and guided between a pair of tension rolls that are pivotally supported at both ends of a connecting piece. ,
The central part of the connecting piece is pivoted and the connecting piece is rotatably formed with an adjusting screw via an operating rod, so that the tension of the wire can be adjusted smoothly and freely according to the rotation angle of the pair of tension rolls. The rotor can be adjusted and always kept in place, and the adjustment operation is extremely easy by simply turning the adjustment screw on the side of the shoe attachment plate, which is an excellent feature and practical feature that allows the shoe attachment plate to be securely attached to the ski board. It is something that has a nature.
