Prototype 1 - The Shmock-Up
This shmock-up, titled Andy the Mountain Man Shoot and Climber, consists of an
army trooper that contains two mechanisms for his goal of climbing vertically
towards a desired destination in a combat pursuit during his assigned mission.
These two mechanisms are a “bazooka” style launcher with a rubber band that
launches the grappling hook up to a desired location and a retractable string
attached to the grappling hook, which is to be pulled out and clamped prior to
launch and released after launch of the grappling hook in order for the army
man to ascend up. The bazooka launcher is a simple tube with a cylinder that
is forced outward using a rubber band wrapped around the end of the tube and
is mounted on the army man’s hands for him to hold while launching the
grappling hook. The retractable device consists of a radial wound spring that
forces the string to be pulled back in after being pulled out and is mounted
in a waist pouch.
Prototype 2 - The Interim Prototype
This view below shows the army man with his existing spring loaded climbing device,
as well as an additional spring that was tested for possible stronger retraction.
The army man will no longer be powered by a spring due to lack of strength of the
recoil springs. Also, the launcher will use a linear spring instead of a rubber band
to launch the grappling hook due to difficulty and inconsistency of the launching
with a rubber band set up. It will be equipped with an electric motor with a gear
train to a spindle that will pull the army man up after launching the grappling
hook with a spring loaded launcher to a desired location. It is preferred to have a
ratcheting or release device on the spindle so that the string for the grappling hook
will be easier to pull out prior to launch. This set up should work well providing
all of the necessary components can be assembled properly.
