Abstract

The invention is a back brace with a stacked pulley tightening device that allows a user to quickly, efficiently, and easily tighten the back brace around the user after the back brace is donned. The pulleys provide a mechanical advantage. Additionally, the present invention includes a segmented belt portion such that a single pulley tightening device can be used to tighten around users of any size.

Claims

1. An orthotic tightening device comprising:

wherein said first pulley and said second pulley are combined in a stacked configuration;

wherein each of said one or more user cords are attached to said first pulley;

wherein each of said one or more compression cords are attached to said second pulley, pass through one of said one or more secondary housings, and are secured to the same main pulley housing; and

wherein when a user pulls said one or more user cords, said one or more main pulley housings and said one or more secondary housings are drawn toward each other.

2. The orthotic tightening device of claim 1, wherein said first pulley has a diameter that is greater than a diameter of said second pulley, such that a mechanical advantage is gained when said one or more user cords are pulled such that said one or more main pulley housings and said one or more secondary housings are drawn toward each other.

3. The orthotic tightening device of claim 2, further comprising:

one or more panels; and

an orthotic device;

wherein said orthotic device is donned by said user;

wherein said one or more panels are attached to said orthotic device;

wherein said one or more main pulley housings and said one or more secondary housings are attached to one of said one or more panels, such that when said one or more user cords are pulled and when said one or more main pulley housings and said one or more secondary housings are drawn toward each other, said orthotic device is tightened around said user wearing said orthotic device.

4. The orthotic tightening device of claim 3, wherein said orthotic device is a back brace;

wherein said back brace is comprised of a lumbar pad and a plurality of side portions;

wherein said plurality of side portions are comprised of one or more segments;

wherein said plurality of side portions are configured to wrap around said user and detachably connect to each other; and

wherein said one or more segments are configured to detachable connect to each other.

5. The orthotic tightening device of claim 4, wherein there are at least two segments on each of said plurality of side portions, such that said user is able to adjust a length of said plurality of side portions to fit a plurality of differently sized users.

6. The orthotic tightening device of claim 5, further comprising:

one or more handles;

wherein said one or more handles are attached to said one or more user cords, such that said user may use said one or more handles to pull on said one or more user cords.

7. The orthotic tightening device of claim 6, wherein there are two panels;

wherein there are two main pulley housings;

wherein there are two secondary housings;

wherein there are two user cords;

wherein there are two compression cords;

wherein there are two handles; and

wherein there are two side portions.

8. The orthotic tightening device of claim 7, wherein said two side portions form a belt of said back brace;

wherein said two panels are each attached to a different side portion of said two side portions, such that said two panels are facing each other in parallel manner;

wherein each of said two panels includes one of said two main pulley housings and one of said two secondary housings such that each of said two main pulley housings is directly across from a corresponding secondary housing, such that two pulley sets are formed with a first pulley set above a second pulley set, such that each of said two pulley sets tighten independently of each other.

9. The orthotic tightening device of claim 8, wherein each of said two pulley sets includes one compression cord and one user cord.

10. The orthotic tightening device of claim 9, wherein said two handles detachably engage with said side portions after said user has tightened said tightening device, such that said tightening device is kept in a tightened state until said user loosens said tightening device.

11. The back brace from claim 10, further comprising:

a cover;

wherein said cover is positioned over said tightening device.

12. An orthotic back brace with a stacked pulley tightening device comprising:

a lumbar pad;

two side portions; and

a tightening device;

wherein said tightening device is comprised of a plurality of pulley sets;

wherein each of said plurality of pulley sets is comprised of a main pulley housing, a secondary housing, a user cord, and a compression cord, such that there are a plurality of main pulley housings, a plurality of secondary housings, a plurality of user cords, and a plurality of compression cords; and

wherein each of said plurality of main pulley housings has a stacked pulley, such that there is a plurality of stacked pulleys.

13. The orthotic back brace of claim 12, wherein each of said plurality of stacked pulleys has at least a first pulley and a second pulley, such that there are plurality of first pulleys and a plurality of second pulleys;

wherein each of said plurality of first and second pulleys are combined in a stacked configuration;

wherein each of said plurality of user cords are attached to one of said plurality of first pulleys;

wherein each of said plurality of compression cords are attached to one of said plurality of second pulleys, pass through one of said at least one secondary housings, and are secured to the same main pulley housing in which said second pulley is located; and

wherein when a user pulls said plurality of user cords, said plurality of main pulley housings and said plurality of secondary housings are drawn toward each other.

14. The orthotic back brace of claim 13, wherein said plurality of first pulleys have a diameter that is greater than a diameter of said plurality of second pulleys, such that a mechanical advantage is gained when said plurality of user cords are pulled such that said plurality of main pulley housings and said plurality of secondary housings are drawn toward each other.

15. The orthotic back brace of claim 14, wherein there are two pulley sets;

wherein said tightening device is further comprised of two panels;

wherein said two panels are each attached to a different side portion of said two side portions, such that said two panels are facing each other in parallel manner; and

wherein each of said two panels includes one of said two main pulley housings and one of said two secondary housings such that each of said two main pulley housings is directly across from a corresponding secondary housing, such that said two pulley sets are positioned with a first pulley set above a second pulley set, such that each of said two pulley sets tightens independently of the other.
