1. Field of the Invention
The present invention relates to a stirrup, and more particularly to an ankle stirrup.
2. Description of Related Art
A conventional ankle stirrup comprises a holder and multiple belts. The belts are mounted on the holder. The holder is formed in an L-shape in section to be applied under an ankle of a user. The belts are mounted around a leg of the user, such that the ankle stirrup is applied for fixing the ankle of the user.
However, when the user lies on a bed, the legs of the user may turn relative to the bed, so a fixing effect for the ankle of the user may be decreased. The conventional ankle stirrup is not suitable to be used while the user is sleeping in bed. Therefore, the conventional ankle stirrup should be improved to resolve the aforementioned problem.
The main objective of the present invention is to provide an improved ankle stirrup to resolve the aforementioned problem.
The ankle stirrup comprises an ankle holder, a positioning unit, and multiple mounting belts.
The ankle holder comprises a leg portion comprising a hole formed through the leg portion, and a foot portion.
The positioning unit is mounted in the hole of the ankle holder, and comprises a body being elongated and having a longitudinal direction and a rotatable portion formed on a front side of the body, the rotatable portion inserted through, engaging, and being rotatable relative to the hole. The positioning unit further comprises a limiting portion detachably mounted in the rotatable portion to keep the rotatable portion from detaching from the hole.
The mounting belts are mounted on the ankle holder.
Other objectives, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The ankle holder 10 is formed in an L-shape in section, and comprises a holder space 11 formed in a front side of the ankle holder 10. The ankle holder 10 comprises a leg portion 12 and a foot portion 13 connected with the leg portion 12. Alternatively, the leg portion 12 may be two individual parts that are connected with the each other by the positioning belts 30. In use, a foot of a user treads on the foot portion 13, and a leg of the user is supported by the leg portion 12. The ankle holder 10 further comprises two pairs of positioning belt holes 14. One pair of the positioning belt holes 14 is formed in a right side of the ankle holder 10, and the other pair of the positioning belt holes 14 is formed in a left side of the ankle holder 10. The positioning belt holes 14 of each pair are respectively formed in the leg portion 12 and the foot portion 13. With reference to
The positioning unit 20 is mounted in the hole 121 of the ankle holder 10, and comprises a body 21, a rotatable portion 22, and a limiting portion 23. The body 21 is elongated and has a longitudinal direction. The rotatable portion 22 is formed on a front side of the body 21 and is inserted through the hole 121. The rotatable portion 22 is rotatable relative to the hole 121 and comprises two first engaging blocks 221, two second engaging blocks 222, two protrusions 223 and two limiting blocks 224. The first engaging blocks 221 and the second engaging blocks 222 are formed on and protrude from the body 21 at intervals, and are inserted through the hole 121. The protrusions 223 are respectively formed on the first engaging blocks 221 and engaged in two of the recesses 122. The limiting blocks 224 are respectively formed on the second engaging blocks 222 and abut the leg portion 12 to keep the body 21 from detaching from the leg portion 12. The limiting portion 23 is detachably mounted among the first engaging blocks 221 and the second engaging blocks 222.
The positioning belts 30 are respectively mounted on the two pairs of positioning belt holes 14 of the ankle holder 10. Each positioning belt 30 has a top end and a bottom end. The top ends of the two positioning belts 30 are respectively connected with one pair of the positioning belt holes 14 which are located at the leg portion 12, and the bottom ends of the two positioning belts 30 are respectively connected with the other pair of the positioning belt holes 14 which are located at the foot portion 13. Therefore, each positioning belt 30 is connected between the leg portion 12 and the foot portion 13. The mounting belts 40 are mounted on the ankle holder 10. Two ends of each mounting belt 40 are respectively mounted on the right side and the left side of the ankle holder 10.
In use, the user wears the ankle stirrup, wherein the foot and the leg of the user are inserted into the holder space 11. The foot of the user corresponds to the foot portion 13 in position, the leg of the user corresponds to the leg portion 12 in position. The mounting belts 40 are applied for keeping the ankle stirrup from detaching from the leg and the foot of the user.
With reference to
When the body 21 is rotated to be perpendicular to the extension direction of the leg portion 12, the ankle stirrup can be fixed and is not to be turned relative to the bed. Therefore, a fixing effect for an ankle of the user can be improved. Furthermore, each positioning belt 30 is connected between the leg portion 12 and the foot portion 13 to further improve the fixing effect for the ankle of the user.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
