Redundant adjustable lanyard
A lanyard for attaching a user's harness to a moveable member of a challenge course. The lanyard may comprise an upper section, a lower section, and a midsection arranged therebetween. The upper section may comprise an upper outer loop and an upper inner loop arranged within the upper outer loop, which form an opening configured to attach to the moveable member, and one or more structural connections. The lower section may comprise a lower outer loop and a plurality of lower inner loops configured to receive a coupling device for the harness. The plurality of lower inner loops may be sequentially arranged within the lower outer loop and attached to the lower outer loop via double shear connections.
1. A lanyard for attaching a harness worn by a user to a moveable member mounted within a challenge course, the lanyard comprising:
an upper section having an upper outer loop, an upper inner loop, and a moveable member attachment opening, the moveable member attachment opening formed by the upper outer loop and the upper inner loop, the upper inner loop arranged within the upper outer loop, the upper section comprising one or more structural connections joining the upper outer loop and the upper inner loop together; and
a lower section having a lower outer loop and a plurality of lower inner loops configured to receive a harness coupling device, the plurality of lower inner loops sequentially arranged within the lower outer loop, each of the plurality of lower inner loops being attached to the lower outer loop via a double shear connection;
wherein the upper outer loop has an exterior surface and an interior surface, the upper inner loop has an exterior surface and an interior surface, and the exterior surface of the upper inner loop faces the interior surface of the upper outer loop;
wherein the lower outer loop has an exterior surface and an interior surface, each of the plurality of lower inner loops has an exterior surface and an interior surface, and the exterior surface of each of the plurality of lower inner loops faces the interior surface of the lower outer loop.
2. The lanyard of claim 1 , further comprising a midsection arranged between the upper section and the lower section, the midsection having at least two layers of material.
3. The lanyard of claim 2 , wherein a single piece of material forms at least the upper outer loop, the lower outer loop, and the midsection.
4. The lanyard of claim 3 , wherein the single piece of material further forms the upper inner loop.
5. The lanyard of claim 1 , wherein a single piece of material forms at least the upper outer loop and the lower outer loop.
6. The lanyard of claim 5 , wherein the single piece of material further forms the upper inner loop.
7. The lanyard of claim 1 , wherein a single piece of material forms the upper outer loop and the upper inner loop.
8. The lanyard of claim 1 , wherein the upper outer loop and the upper inner loop are formed from different pieces of material.
9. The lanyard of claim 1 , wherein the lower outer loop and the plurality of lower inner loops are formed from different pieces of material.
10. The lanyard of claim 9 , wherein each of the plurality of lower inner loops is formed by a piece of material folded over to form a loop, with ends of said piece of material facing upward within the lower outer loop, and the double shear connection joins the ends of said piece of material to the lower outer loop.
11. The lanyard of claim 1 , wherein the upper section comprises a plurality of structural connections, a plurality of layers of material provided by the upper outer loop, and a plurality of layers of material provided by the upper inner loop below the movable member attachment opening.
12. The lanyard of claim 11 , wherein at least one of the plurality of structural connections joins layers of the upper outer loop together.
13. The lanyard of claim 11 , wherein at least one of the plurality of structural connections joins layers of the upper inner loop together.
