Abstract
An apparatus including a first housing; a second housing slidably connected to the first housing along a substantially straight linear path between a first position and a second position; and a biasing system configured to alternatively bias the second housing towards the first position and the second position. The biasing system includes a linkage connected to the first and second housings and a spring connected between the first housing and the linkage.
Claims18
An apparatus comprising:
- a first housing;
- a second housing slidably connected to the first housing along a substantially straight linear path between a first position and a second position;
- and
- a biasing system configured to alternatively bias the second housing towards the first position and the second position, wherein the biasing system comprises a linkage connected to the first and second housings and a spring connected between the first housing and the linkage, where the linkage comprises a one-piece linkage arm having a middle section forming a pivot location, and two arm sections extending from the middle section at an obtuse angle between two arm sections.

An apparatus comprising:
- a first housing;
- a second housing slidably connected to the first housing along a linear path between a first position and a second position;
- and
- a biasing system comprising a linkage arm and a spring, wherein the linkage arm comprises a first end pivotably connected to the first housing at a pivotal connection and a second end slidably connected to the second housing, wherein the spring comprises a first end connected to the first housing and a second end connected to the linkage arm, wherein the first end of the spring is spaced from the pivotal connection of the first end of the linkage arm with the first housing, and wherein the biasing system is configured to bias the second housing towards the first position and alternatively toward the second position, where the linkage arm has a middle section at the pivotal connection, and two arm sections extending from the middle section at an obtuse angle between two arm sections.
1 more element
A method comprising:
- slidably connecting a first housing with a second housing;
- and
- connecting a biasing system to the first and second housings, wherein the biasing system is configured to bias the second housing towards a first position relative to the first housing and alternatively towards a second position relative to the first housing, wherein the biasing system comprises a linkage between the first and second housings and a spring connected between the first housing and the linkage, wherein the linkage comprises a middle section, and two arm sections extending from the middle section at an obtuse angle between two arm sections, where the middle section is pivotably connected to the second housing by a middle pivot, where the first arm comprises a first end pivotably connected to the first housing at a pivotal connection and the second arm comprises a second end slidably connected to the second housing, wherein the spring comprises a first end connected to the first housing and a second end connected to the linkage arm, wherein the first end of the spring is spaced from the pivotal connection of the first end of the linkage arm with the first housing.
