Abstract

A lever mechanism for sealing a telecommunications closure includes a plurality of hinge elements; a leveraging element extending upwardly from each hinge element; an arm section extending from the leveraging element; a biasing element downwardly extending from the arm section; and a handle coupled to the biasing element such that upon application of a compressive force to at least a portion of the handle, each hinge element, each leveraging element, each arm section, and each biasing element moves, allowing the lever mechanism to change from a non-actuated position to an actuated position. The lever mechanism is further configured to couple with a spring-activated element and environmentally seal the telecommunications closure.

First claim

The invention claimed is:

1. A lever mechanism for sealing a telecommunications closure, the lever mechanism comprising:
a plurality of hinge elements;
a leveraging element extending upwardly from each hinge element;
an arm section extending from the leveraging element;
a biasing element downwardly extending from the arm section; and
a handle coupled to the biasing element such that upon application of a compressive force to at least a portion of the handle, the hinge element, the leveraging element, and the arm section, the biasing element moves, allowing the lever mechanism to change from a non-actuated position to an actuated position, wherein in the actuated position, the lever mechanism is configured to couple with a spring-activated element and environmentally seal the telecommunications closure.

2. The lever mechanism of claim 1 , wherein the hinge element is configured as an insertable male-type hinge element configured for insertion into a complementary female-type receiving element disposed on the telecommunications closure.

3. The lever mechanism of claim 1 , wherein the leveraging element curves upwardly and downwardly to form a c-shape.

4. The lever mechanism of claim 1 , wherein the spring-activated element comprises a torsion spring.

5. The lever mechanism of claim 1 , wherein the spring-activated element is configured as a clip.

6. The lever mechanism of claim 5 , wherein the clip comprises at least two slotted sections configured to mate with a portion of the telecommunications closure.

7. A sealing system for a telecommunications closure, comprising:
a lever mechanism, comprising a plurality of hinge elements;
a leveraging element extending upwardly from each hinge element;
an arm section extending from the leveraging element;
a biasing element downwardly extending from the arm section;
a handle coupled to the biasing element such that upon application of a compressive force to at least a portion of the handle, the hinge element, the leveraging element, and the arm section, the biasing element moves, allowing the lever mechanism to change from a non-actuated position to an actuated position, wherein in the actuated position, the lever mechanism is configured to couple with a spring-activated element and environmentally seal the telecommunications closure; and
a spring-activated element coupled to the lever mechanism.
