A carrier for a window sash has a balance connecting portion configured to be connected to a window balance. A vertical rail system is configured to slidingly engage a bracket of the window sash.
1. A carrier for a window sash comprising:
a body comprising a balance connecting portion configured to be connected to a window balance, wherein the body at least partially defines a brake opening;
a brake at least partially movably disposed in the brake opening;
a vertical rail system secured to the body, wherein the vertical rail system is configured to slidingly engage a bracket of the window sash.
2. The carrier of claim 1 , further comprising a sliding surface disposed opposite the vertical rail system, wherein the sliding surface is adapted to slide in a jamb channel of a window jamb.
3. The carrier of claim 1 , further comprising a guide disposed proximate the vertical rail system, wherein the guide is configured to slidingly engage the bracket of the window sash.
4. The carrier of claim 3 , wherein the vertical rail system is integral with the body.
5. The carrier of claim 3 , wherein the guide comprises a lock for releasably engaging the bracket.
6. The carrier of claim 5 , wherein the lock is engaged with the brake.
7. The carrier of claim 5 , wherein a position of the lock is dependent on a position of the brake.
8. The carrier of claim 7 , wherein when the brake is in a stored position, the lock is in an extended position.
9. The carrier of claim 8 , wherein when the brake is in an extended position, the lock is in a projected position.
10. The carrier of claim 9 , wherein when the brake is in a deployed position, the lock is in a retracted position.
11. The carrier of claim 5 , wherein the vertical rail system at least partially defines a bracket receptor, and wherein the lock is configured to extend into the bracket receptor and retract from the bracket receptor.
12. The carrier of claim 1 , wherein the brake is engaged with the balance connecting portion when in a deployed position.
13. A balance system for a window sash, the balance system comprising:
a bracket adapted to be secured to the window sash, the bracket comprising a vertical carrier mating element and an interface surface, wherein the vertical carrier mating element comprises at least one elongate projection; and
a carrier adapted to be connected to a window balance, the carrier comprising a body defining a vertical bracket mating element and a bearing surface, wherein the vertical bracket mating element comprises at least one elongate channel, and wherein the at least one elongate channel is configured to slidingly engage with the at least one elongate projection and the bearing surface is configured to engage with the interface surface, when the vertical carrier mating element is engaged with the vertical bracket mating element.
14. The balance system of claim 13 , wherein the carrier further comprises a brake connected to the body, wherein the brake is positionable in a stored position wherein the brake is disposed substantially within the body and an extended position wherein the brake extends from the body.
15. The balance system of claim 14 , further comprising a pivotable lock adapted to prevent disengagement of the bracket from the carrier, wherein the pivotable lock is positionable in a locked position wherein the pivotable lock is engaged with the bracket and an unlocked position where the pivotable lock is disposed substantially within the body.
16. The balance system of claim 15 , further comprising a biasing element for biasing the pivotable lock into the unlocked position.
17. The balance system of claim 16 , wherein the pivotable lock biases the brake into the extended position.
18. A method of installing a window sash on a carrier of a window balance, wherein the carrier is disposed in a window jamb, the method comprising:
extending a brake from the carrier;
engaging the brake with an opening in the window jamb;
engaging a window sash bracket with the carrier, wherein the window sash bracket is engaged with the carrier by slidingly engaging at least one elongate projection from the window sash bracket with at least one elongate channel defined within the carrier; and
storing the brake substantially within the carrier, wherein storing the brake substantially simultaneously extends a lock into a recess in the window sash bracket.
19. The method of claim 18 , further comprising, prior to storing the brake, disengaging the brake from the opening.
20. The method of claim 18 , wherein the sash bracket is connected to the window sash.
