Abstract:
1. A spring system comprising first and second housings and a first mechanical spring securely connected to both said first and second housings, said first and second housings each including a front portion having a front end and rear portion having a rear end and an internal chamber, said rear end of said second housing telescopically inserted into said internal chamber of said first housing at said front end of said first housing, said first and second housings being connected together to prevent separation of said first and second housings from one another, said first and second housings moveable relative to one another; said first housing having a first housing opening into said internal chamber at said front end, said first housing opening having a first cross-sectional area, said second housing having a second housing opening into said internal chamber at said rear end, said second housing opening having a second cross-sectional area, said first cross-sectional area smaller than said second cross-sectional area thereby inhibiting said rear portion of said second housing from disengaging from and fully passing through said first housing opening when said rear portion of said second housing is positioned in said internal chamber of said first housing, said first mechanical spring having a first end portion with a first end and a second end portion with a second end and a void inner region that at least partially extends between said first and second ends, said first mechanical spring is at least partially positioned in said internal chamber of said first and second housings, said first end portion of said first mechanical spring is connected to a first connection arrangement in said chamber of said first housing, said second end portion of said first mechanical spring is connected to a second connection arrangement in said chamber of said second housing, said first connection arrangement threadedly engages said first end portion of said first mechanical spring to prevent said first mechanical spring from disengaging from said first housing when said first and second housings move relative to one another, said second connection arrangement threadedly engages said second end portion of said first mechanical spring to prevent said first mechanical spring from disengaging from said second housing when said first and second housings move relative to one another, said first mechanical spring fully contained within said internal chambers of said first and second housing when said first and second housings are connected together.
