    I have seen this intersting product on the youtube.
    There are some claws/gears on top of the cocking rod. In order to keep the holding device stable,there must be a ratchet to bear those claws like Greek's gastraphetes.
    But what puzzled me is that after the man release the arrow, he pull back the cocking rod a litter first, then push forward the cocking rod to catch the bow string.
    If there is a ratchet mechanism, he can't simple push forward the rod without disengaging the ratchet and claws.
    Anyone can explain its working mechanism, sorry I can't post any picture in this topic.

    This bow is just like a standard bow ,except is it very short. It is shot by sliding the release down the rod and then you grab the string with it. Now you pull the bow all the way back and the trigger will lock on the rod. You put an arrow on the bow now , as it is ready to shoot. Place the trigger on your face for anchor point, take a careful aim and press the release button.Some states won't allow this setup.These have been around for a long time and just never have been accepted.Some may call it a vertical crossbow

    The stay rod with attached release aid moves in the riser as per the you tube clip.

    I'm guessing the toothed end of the rod and ratchet system is released by a small thumb catch or button on the upper side of the grip (can't be seen in the clip)

    I have this same bow. For the money, it is fantastic fun, compact, and shoots extremely well!

    A downside is that draw length can't be adjusted, and it is factory set at 28"
    Not a fan of the included release aid either.

    Correct ,  in my opinion, that's mostly why they never took off. First the bow was designed , a friend has one . It is shot as a  conventional bow with the exception that you have to use a release. That never took off either. The owner of the company sold to where it is now. I've been shooting and hunting for over 55 years.  I'll still shoot in the 50s for x count. I've seen a lot of this stuff come and go.I almost believe that there are no more wheels to invent. On the draw length I'm thinking you could make a mod  to fit just you.

    Thank you c sitas for your explanation.
    In my view, the concept of this bow/crossbow is not the same as the in line vertical crossbow, since its trigger system is floating and movable. 
    After release, this man just pull the cocking rod forward without reset the ratchet like 
    operating the gastraphetes. This is the main point for this design. 
    If I can search the patent, then the question is solved.
