Abstract:
1. In a shade system with a bracket supporting a shade storage roll having a shade, and a modular anti-reversible power spring apparatus, the shade system comprising: a first housing having an exterior surface, a receiver end and a connector end wherein the first housing encloses a first anti-reversible biasing member; at least one connector connected with the connector end of the first housing; at least one receiver connected with the receiver end of the first housing; the first anti-reversible biasing member having a first end and a second end wherein the first end is connected to the first housing and the second end includes a feature; a second housing having an exterior surface, a receiver end and a connector end wherein the second housing encloses a second anti-reversible biasing member; at least one connector connected with the connector end of the second housing; at least one receiver connected with the receiver end of the second housing; the second anti-reversible biasing member having a first end and a second end wherein the first end is connected to the second housing and the second end includes a feature; wherein the at least one connector of the first housing and the at least one receiver of the second housing selectively lock the first housing and the second housing together thereby preventing unintentional separation of the first housing and the second housing; wherein the first housing and the second housing are connected to the shade storage roll; a support connected with the bracket; the support having a groove; wherein the feature of the first anti-reversible biasing member is received within the groove of the support and the feature of the second anti-reversible biasing member is received within the groove of the support; wherein the shade storage roll rotates around the support; wherein when the shade storage roll is rotated in a first direction, the feature of the first anti-reversible biasing member and the feature of the second anti-reversible biasing are held in place in the groove of the support; wherein when the shade storage roll is rotated in a second direction, opposite the first direction, the groove of the support allows passage of the feature of the first anti-reversible biasing member and the feature of the second anti-reversible biasing member out of the groove so as to prevent reverse or back winding of the first anti-reversible biasing member and the second anti-reversible biasing member.
