Many tourists appreciated stankovye backpacks. They have a lightweight but durable rigid frame which provides a soft, in fact, haversack convenient box-like shape, more advantageous for laying the stowed cargo and carrying it on his back. But what about those who already have a backpack? Suggest to equip it with a built-in collapsible a frame of duralumin pipes. It will handle the load no worse frame easel purchase of a backpack. Besides, unlike the latter, can usefully stand for you in camp three of the four tubes are easily removed from the backpack and being connected together into, for example, in a solid rack. I have it, in particular, serves as the sole support of a makeshift tent tent.
To equip a backpack collapsible frame will not require a major rebuilt. You only need to sew on the outside of the bag facing the back, on the level of attachment of the upper ends of the straps, narrow oblong drawstring. It is inserted into the cross member — slightly tapered duralumin tube mounted on the ends of the sleeves, which includes a vertical tubular stand. And where are the lower straps, rack mounted metal hooks with a vertical spike.
Portable machine for backpack:
1 — top crossbar 2 — strap backpack, 3 — rail, 4 — rod-bracket; 5 — strut 6 — hook 7 — drawstring
To build the frame two tubes-stand inserts on top of sleeve the crossmember and put on spikes hooks. At the top of these tubes are connected to another transverse tube, which is fixed by means of two drop-in brackets-rods, sharpened one — under Shiloh, the other under the screwdriver. They will also be able to make the trip extra features.
