Description

Binding For Sports boots {Binding For Sports boots}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding for sports boots, and more particularly to a binding for sports boots in which the sports boots can be easily mounted on snowboards and ski boards.

Snowboarding and skiing are typical winter sports using sport boots. In order to enjoy snowboarding and skiing, it is necessary to install bindings that attach sports boots to decks such as snowboards and ski boards.

Conventional snowboard binding techniques have a cumbersome and inconvenient problem in that it is necessary not only to repeatedly perform sitting and standing posture for mounting and dismounting in a strap manner, but also to fastening and loosening a plurality of straps. In addition, the conventional ski binding technology has a problem in that the versatility is deteriorated due to the use of dedicated boots and dedicated bindings.

Conventionally, Korean Patent No. 10-1438174 discloses bindings for sports boots. Korean Patent No. 10-1438174 discloses a technique of applying a tensile force to the first wire 72, the second wire 74 and the third wire 86 by bringing the lever 64 into close contact with the high bag 56 And it is possible to mount the binding conveniently. The first wire 72 and the second wire 74 and the third wire 86 can be released by releasing the lever 64 from the high bag 56 at the time of detachment. And the strength of the tensile force generated on the wire can be controlled through the displacement adjusting part provided on the side wall 16. [

However, Korean Patent Registration No. 10-1438174 has a disadvantage in that the tensile force generated on the wire is not constant and the wire loosens over time. Therefore, the feeling of wearing is different when wearing.

Conventionally, Korean Patent Laid-Open Publication No. 10-2007-0025943 discloses bindings for sports boots. Korean Patent Laid-Open Publication No. 10-2007-0025943 discloses that when the tightening means 120 is turned, a tensile force is generated on the wire W by a winding device installed inside, and the strap 110 and the base plate 102 So that the boots B are fixed.

However, Korean Patent Laid-Open Publication No. 10-2007-0025943 has a disadvantage in that there is no means for fixing the heel of the boot with a structure in which a tensile force is generated only at the foot portion of the boot.

In addition, Korean Registered Patent No. 10-1438174 and Korean Patent Publication No. 10-2007-0025943 require manual operation of the binder. Therefore, there is the inconvenience of sitting up and standing up for mounting.

The lower frame part 200 of the binding for sports boots according to the embodiment of the present invention includes a first rotation groove 230 and a second rotation groove 240. A second rotary groove spacing space 242 is formed in the second rotary groove 240 so that the engagement protrusion 543 of the second rotary rod 540 can flow in the rotation axis direction.

The first rotation groove 230 is provided with a first rotation groove engagement groove 231 in which the engagement projection 543 of the second rotation rod 540 can be received, A second rotation groove engaging groove 241 in which the engaging projection 543 of the second rotating rod 540 can be received is provided.

Therefore, when the second rotating rod 540 moves to the other side, the engaging protrusion 543 is released from engagement with the first rotation groove locking groove 231 and the second rotation groove locking groove 241, 540 rotate freely. When the engaging protrusions 543 are engaged with the first and second rotation grooved grooves 231 and 241, the second rotating rod 540 is moved to one side, 540 are fixed.

At this time, the elastic body 546 exerts an elastic force to move the second rotating rod 540 in the other direction through the rod projection 545. That is, the elastic body 546 generates an elastic force in a direction in which the rotation of the second rotating rod 540 is fixed.

The first rotary bar 520 is rotated in one direction and the rail groove 522 and the rail projection 532 are rotated in the same direction as shown in FIG. The second rotating bar 530 connected to the first rotating bar 520 rotates in the other direction. 'B' in FIG. 6 shows a state in which the rotation is completed.
