Abstract
In example implementations, a braking system for a vertical stacking panel door is provided. The braking system includes a first rod, a strap coupled to the first rod, a second rod movably coupled to the first rod, wherein the second rod is to engage a linear ratchet when moved from a disengaged position to an engaged position, and a torsion spring coupled to the first rod and the second rod, wherein tension from the strap moves the second rod into the disengaged portion and the torsion spring moves the second rod into the engaged position when tension is lost on the strap.
Claims20
A braking system for a vertical stacking panel door, comprising:
- a housing, wherein the housing comprises angled slots;
- a first rod coupled to the angled slots of the housing in an interior volume of the housing;
- a strap comprising a loop on an end of the strap, wherein the strap is coupled to the first rod via the loop;
- a second rod movably coupled to the housing, wherein the second rod is to engage a linear ratchet when moved from a disengaged position to an engaged position;
- and
- a torsion spring, wherein an end of the torsion spring interacts with the second rod, wherein tension from the strap moves the first rod within the angled slots and causes the torsion spring to rotate in a first rotational direction to cause the second rod to move into the disengaged position, and the torsion spring rotates in a second rotational direction to allow the first rod to move within the angled slots of the housing such that the end of the torsion spring and the movement of the first rod cause the second rod to move into the engaged position when tension is lost on the strap.

An end cap for a bottom most panel of a vertical stacking panel door, comprising:
- at least one track wheel located along an outer side to move along a track system of the vertical stacking panel door system;
- at least one roller located on a back side;
- a brake located on a bottom end of the end cap, wherein the brake comprises:
- a housing, wherein the housing comprises angled slots;
- a control rod coupled to the angled slots of the housing in an interior volume of the housing;
- a strap comprising a loop on an end of the strap, wherein the strap is coupled to the control rod;
- a brake rod, wherein the brake rod is to move between a disengaged position and an engaged position;
- and
- a torsion spring, wherein an end of the torsion spring applies a first force to the brake rod and the strap applies a second force to the control rod,
- wherein the brake rod is in the disengaged position when the second force of the strap is greater than the first force of the torsion spring, and the strap provides an upward force on the control rod that moves the control rod within the angled slots to allow the torsion spring to rotate in a first rotational direction such that the brake rod moves in a downward and inward direction, and the brake rod is in the engaged position when the second force of the strap is less than the first force of the torsion spring to allow the torsion spring to rotate in a second rotational direction such that the end of the torsion spring acts against the brake rod to move the brake rod in an upward and outward direction.

A vertical stacking panel door system with a braking system, comprising:
- a track system;
- a linear ratchet coupled to a door jamb adjacent to the track system;
- and
- a vertical stacking panel door movably coupled to the track system, wherein the vertical stacking panel door comprises a plurality of disconnected panels, wherein a bottom most panel of the plurality of disconnected panels comprises a brake, the brake comprising:
- a housing, wherein the housing comprises angled slots;
- a first rod coupled to the angled slots of the housing in an interior volume of the housing;
- a strap comprising a loop on an end of the strap, wherein the strap is coupled to the first rod via the loop;
- a second rod movably coupled to the housing, wherein the second rod is to engage the linear ratchet when moved from a disengaged position to an engaged position;
- and
- a torsion spring, wherein an end of the torsion spring interacts with the second rod, wherein tension from the strap moves the first rod within the angled slots and causes the torsion spring to rotate in a first rotational direction to cause the second rod to move into the disengaged position, and the torsion spring rotates in a second rotational direction to allow the first rod to move within the angled slots of the housing such that the end of the torsion spring and the movement of the first rod cause the second rod to move into the engaged position when tension is lost on the strap.
