The present invention relates to a support brace, and more particularly to a support brace that is length-adjustable.
In order to facilitate a fracture to recover as soon as possible, when taking care of a patient suffering from a limb fracture, the medical staff fixes the fracture by orthopedic cast or other appliances of orthotics. The orthopedic cast and the appliances of orthotics cover the fracture and provide the fracture with both protection and supporting forces, thereby keeping the fracture from being moved unintentionally and prevent the fracture from damage again. The fracture can gradually recover in a still state.
However, limb length varies from one person to another, but the orthopedic cast and conventional appliances of orthotics are fixed in length and cannot fit the varying limb lengths of different persons. The orthopedic casts of different sizes require different molds for casting, and the conventional appliances of the orthotics of various sizes have to be purchased. Therefore, casting of the orthopedic cast and purchasing of the conventional appliances of orthotics that are not length-adjustable cost a lot.
To overcome the shortcomings of the orthopedic cast and the conventional appliances of orthotics, the present invention provides a support brace to mitigate or obviate the aforementioned problems.
The main objective of the present invention is to provide a support brace that is longitudinally adjustable for various limb lengths of different users.
The support brace comprises a conjoining component, an extending component, a guiding set, an adjusting set, and an operating set. The guiding set has a guiding pole mounted to the conjoining component. The adjusting set is mounted to the extending component and has an adjusting sheet with a through hole located around and engaged with the guiding pole. The operating set has a pressing pole able to press the adjusting sheet and to disengage the guiding pole from the through hole of the adjusting sheet, and make the extending component to which the adjusting set is mounted moveable relative to the conjoining component along a moving direction. The support brace is longitudinally adjustable, is suitable for different limb lengths of different people, and is able to reduce cost of casting orthopedic cast and purchasing appliances of orthotics of different sizes.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The first connecting portion 11 is formed at the front side of the erect portion of the conjoining component 10 and is disposed adjacent to the lower end of the erect portion of the conjoining component 10. The first connecting portion 11 is a platform for assembling the guiding set 30.
The two pivoting arms 12 are formed at the front side of the erect portion, are disposed below the first connecting portion 11, and extend away from the erect portion of the conjoining component 10. Each one of the two pivoting arms 12 has a pivoting portion disposed distal from the first connecting portion 11.
The holding unit 13 is assembled to the upper end of the erect portion of the conjoining component 10 by two bolts. The fastening bolt 13A is mounted through the first connecting portion 11 upward.
The two engaging protrusions 15 are coaxially and respectively formed at the two pivoting arms 12 and extend to opposite directions.
With reference to
The second connecting portion 21 is formed at the bottom end of the main portion and has a rear limiting part, a first limiting face 211, a front limiting part 25, and a second limiting face 213. The rear limiting part is formed at the rear side of the main portion. The first limiting face 211 is disposed at the rear limiting part and faces downward. The front limiting part 25 is assembled to the rear limiting part by two bolts from the front side of the main portion. The second limiting face 213 is disposed at the front limiting part 25 and faces upward. The second limiting face 213 and the first limiting face 211 are separated by a distance D in the moving direction. The assembling platform 22 is formed at the front side of the main portion and is disposed adjacent to the top end of the main portion. The assembling platform 22 has an upward face and a downward face. The upward face and the downward face respectively face to the top end and the bottom end of the main portion. Each fixing hole 23 of one pair of the two pairs of fixing holes 23 is an elongated hole and is formed through the main portion. The cover 27 is mounted to the main portion by two bolts and covers the assembling platform 22.

The adjusting sheet 41 has a thickness T, a first end, a second end, a through hole 411, and a pressed portion 413. The thickness T is substantially equal to the distance D defined between the first limiting face 211 and the second limiting face 213. The first end and the second end of the adjusting sheet 41 are opposite each other. The first end of the adjusting sheet 41 faces to the rear limiting part of the second connecting portion 21. The second end of the adjusting sheet 41 faces to the front limiting part 25. The through hole 411 is disposed adjacent to the first end of the adjusting sheet 41. The through hole 411 has an outline. The outline of the through hole 411 encloses an area. The through hole 411 is located around the guiding pole 31, and the area enclosed by the outline of the through hole 411 is larger than the area of the cross-section of the guiding pole 31. The pressed portion 413 is disposed at the second end of the adjusting sheet 41. The first elastic unit 43 is a compression spring.
The first elastic unit 43 is mounted around the guiding pole 31 and abuts against both the first end of the adjusting sheet 41 and the second connecting portion 21. The first elastic unit 43 abuts against the first end of the adjusting sheet 41 to make the adjusting sheet 41 obliquely disposed relative to the guiding pole 31 and to make the through hole 411 of the adjusting sheet 41 engaged with the guiding pole 31.

The two pivoting arms 12 of the conjoining component 10 are respectively and pivotally connected to the two connecting arms 11A and respectively fixed to the two connecting arms 11A by two bolts 19. The pair of the positioning protrusions 15 is mounted in one of the multiple pairs of positioning openings 15A.

When the pulling portion 553 is released, the second elastic unit 53 restores and pushes the pressed stick 513 to lift the pressing pole 51, and the pressing pole 51 is detached from the pressed portion 413 of the adjusting sheet 41. The first elastic unit 43 pushes the first end of the adjusting sheet 41 again and makes the through hole 411 of the adjusting sheet 41 and the guiding pole 31 re-engage with each other.
With reference to
The guiding pole 31 may be fixed to the extending component 20, and the adjusting set 40 and the operating set 50 may be mounted to the conjoining component 10.
