## Background
FIELD OF THE INVENTION
The present invention is a CIP of application Ser. No. 14/312,172, filed Jun. 23, 2014, the entire contents of which are hereby incorporated by reference.


BACKGROUND OF THE INVENTION
Description of the Prior Art
A conventional ski shoe is positioned onto a ski board by a fixation seat. Conventional fixation seat disclosed in patents US 2009/0174172, TW 257991, TW 298090, TW 305222, TW 312998, and TW 521636 includes a seat, an ankle protecting board, and a fastening belt. The ankle protecting board is disposed on the upper-rear portion of the seat for an ankle portion of the ski shoe to lean against, and the fastening belt fastens the ski shoe to the seat.
However, the ankle protecting board of a conventional fixation seat is connected to the rear side of the seat and further extends to the left side and the right side of the seat as a single piece. When a user swings his ankles left and right, the seat is also distorted by the swung ankle protecting board so that the balancing is affected. On the other hand, the seat may restrict the action of swinging of the ankle protection board so that the ankle of user may be deviated from the ankle protection board. As a result, protection to the ankle is weakened.
SUMMARY OF THE INVENTION
The main object of the present invention is to provide a fixation seat for ski shoe which is more flexible for distorting.
To achieve the above and other objects, a fixation for ski shoe of the present invention includes a seat, a connecting structure, a support structure, an ankle protecting board, and a fixation structure.
The seat at least has a left side, a right side, and a rear side. The connecting structure is disposed on the seat for a ski board to connect with. The support structure includes a left support element and a right support element. The left support element extends upward and obliquely from the left side of the seat to a left portion of the rear side of the seat, and the right support element extends upward and obliquely from the right side of the seat to a right portion of the rear side of the seat. An end of the left support element located at the rear side of the seat is distant from an end of the right support element located at the rear side of the seat a predetermined distance. Two opposite sides of an end of the ankle protecting board are connected to a top of the left support element and a top of the right support element respectively so that the ankle protecting board is located above the rear side of the seat. The fixation structure is located above the seat. Two opposite ends of the fixation structure are connected to the left side and the right side of the seat respectively so that a shoe-receiving space is enclosed by the fixation structure and the seat. The fixation structure is adapted for fastening a shoe received in the shoe-receiving space with the seat. The end of the left support element and the end of the right support element extend oppositely toward each other to form a gap smaller than 4⁄5 of the rear side of the seat.
Because the support structure bearing the ankle protecting board is divided into two pieces, the left and the right support elements can be deformed respectively when distorting. Thus, the ankle protecting board may move following the ankle of the user to support the ankle of the user. As a result, even if the fixation seat is distorted by the user during ski, the ankle protecting board is able to support the ankle all the time.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

The support edge is closer to the rear side of the seat 10 than the extending edge. The base, the support edge, and the extending edge are formed by metal bars or metal tubes. The bearing element 312 is disposed on an end of the metal frame 311 opposite to the base thereof for the ankle protecting board 40 to dispose on. Similarly, the right support element 32 includes a metal frame 321 and a bearing element 322. The metal frame 321 is substantially obtuse triangle and has a base. The base is disposed on the left side of the seat 10 parallel to the left side of the seat 10. The metal frame 321 further has a support edge and an extending edge. An angle between the base and the support edge is obtuse angle, and the extending edge connects the base and the support edge together. The support edge is closer to the rear side of the seat 10 than the extending edge. The base, the support edge, and the extending edge are formed by metal bars or metal tubes. The bearing element 322 is disposed on an end of the metal frame 321 opposite to the base thereof for the ankle protecting board 40 to dispose on. That is, a conventional support element in a single piece is displaced by the left support element 31 and the right support element 32 which are arranged spacedly in the present invention.
The left support element 31 further includes a left connecting plate 313, and the left connecting plate 313 is assembled to the metal frame 311 and selectively adjustably connected with the seat 10. The seat 10 is formed with a through arched groove 14, and the left connecting plate 313 is selectively adjustably connected with the seat 10 by disposing a pivot mechanism 15 through the through arched groove 14. The right support element 32 further includes a right connecting plate 323, and the right connecting plate 323 is assembled to the metal frame 321 and selectively adjustably connected with the seat 10. The seat 10 is formed with a through arched groove 16, and the right connecting plate 323 is selectively adjustably connected with the seat 10 by disposing a pivot mechanism 17 through the through arched groove 16.
Preferably, the seat 10 includes a front seat 11, a left seat 12, and a right seat 13 The front, left and right seats 11, 12, 13 are individual pieces and each separate from one other. The left seat 12 and the right seat 13 are disposed on two sides of the connecting structure 20 respectively, and the connecting structure 20 is resilient, such as a soft rubber plate. The connecting structure 20 is located between the ankle protecting board 40 and the front seat 11. An end of the left support element 31 is connected with the left seat 12 and a left side of the front seat 11. An end of the right support element 32 is connected with the right seat 13 and a right side of the front seat 11. The left seat 12 is distant from the right seat 13 a predetermined distance to form a gap in a predetermined width. The left seat 12 is rotatably adjustably connected with the left connecting plate 313 of the left support element 31, and the right seat 13 is rotatably adjustably connected with the right connecting plate 323 of the right support element 32. The support structure 30 further includes a linkage 33 which is pivotally connected respectively to the end of the left support element 31 and the end of the right support element 32. This allows the seat 10 to be adjusted within a large range.
Two opposite sides of an end of the ankle protecting board 40 are connected to a top of the left support element 31 and a top of the right support element 32 so that the ankle protecting board 40 is located above the rear side of the seat 10. More specifically, the ankle protecting board 40 includes a left protecting board 41 and a right protecting board 42 which is symmetrical to the left protecting board 41 and is detachably connected with the left protecting board 41. A bottom of the left protecting board 41 is detachably disposed on the left support element 31, and a bottom of the right protecting board 42 is detachably disposed on the right support element 32. Preferably, the ankle protecting board 40 is substantially reverse U-shaped.

Thus, a user can displace one of the protecting boards to meet the user's need.
The fixation structure 50 is located above the seat 10, and two opposite ends of the fixation structure 50 are connected to the left side and the right side of the seat 10 respectively so that a shoe-receiving space is enclosed by the fixation structure 50 and the seat 10. The fixation structure 50 is adapted for fastening a ski shoe received in the shoe-receiving space to the seat 10. Practically, the fixation structure 50 is belt-like. In the present embodiment, two opposite ends of the fixation structure 50 are connected to the left support element 31 and the right support element 32 so as to be connected to the left side and the right side of the seat 10 indirectly.
In use, a ski shoe is received in the shoe-receiving space and is fastened to the seat 10 by the fixation structure 50, and the seat 10 is positioned to a ski board by the connecting structure 20. Thereby, installation is completed. When a user swings his ankles left and right for turning or balancing, the ankle protecting board 40 is swung too so that the torsion is transmitted to the seat 10 via the support structure 30. However, the support structure 30 is divided into the left support element 31 and the right support element 32 which are independent from each other so as to allow deformation respectively, and the seat includes the left seat 12 and the right seat 13 to connect with the left support element 31 and the right support element 32. In addition, the connecting structure 20 is resilient so that the left portion and the right portion of the fixation seat are allowed to be swung and distorted respectively. Besides, the seat 10 may not restrict the ankle protecting board 40 too much due to the elasticity of distortion. Thus, the action of swinging of ankles can be presented perfectly. On the other hand, the ankles of the user are under better protection by supported and held well by the ankle protecting board 40 all the time.
Besides, the ankle protecting board 40 is assembled by two pieces which are detachable respectively, so one can choose desired left protecting board 41 and right protecting board 42 and assemble them to meet the needs.
