Retractable Roller Tent
Introduction: Retractable Roller Tent
Intro.
Hello everyone, this is my first instructable uploaded, so I hope you enjoy this as much as I do!
In Spring and summer season, the sun rises with a hot power who helps a lot of us to different activities, to mention someone's, dries clothes, the painted dry more faster, flowers grows and make a beautiful garden, a good Sun tanning. In my case, there are some special clothes i prefer to wash by hand then washing machine, and especially in this season, the sun hit so strong, that can be a little dangerous to our skin, so, by this, I decided to do a retractable tent to roller up when is not required. This shade will be helpful, I think this can be use for everyone who do activities outside (near a wall) who are looking for a easy way to do a tent with components easy to obtain (who knows? maybe yo have almost all material in your backyard, in the place were we drop all our scrap & unnecessary stuff).
Supplies
To built this tent, we just need the next items:
-Wood as required.
-Continuous thread hex head bolts 2 EA (I used a 5/16" x 3" but is highly recommended to use a wider one).
-Lock Nuts 8 EA (Again, I used for a 5/16" screw but is recommended to use a bigger one).
-Plastic garbage bag 1 EA (A big one).
-Bearings 5 EA (I recycled from a couple of old fidget spinners).
-Nails.
-Screws and anchors.
-Thick thread as required (Don't use a fragile one, try to found a good and resistance rope, wide must be like one bolt thread).
-Staples (and a stapler...).
-Steel tube 5 Ft. 2 EA (The length depends of the height are you looking for).
Step 1: Building the Wood Block Mount.
The first step is built the block mount were the bearings will be placed, for that, we start cutting 5 wood pieces bigger than 1.25" X 2" (it could be exactly, does not important), I used an old scrap wood stopper to do this, the width is constant, i just make a mark every 2 inch and cut each. When finished cutted, we must to make a hole as same diameter like the bearing, commonly, the diameter of the fidget spinners bearings are 22 mm, this is almost 5/8" so I use a hole saw with shaft (orange) just be care to don't exceed the 7 mm deep (is the bearing width). Remove the excess. To finalise this step, we must to remove much wood as possible in the inner diameter made by the drill, to a nut can move freely.
Step 2: Building the Bottom Mechanism.
To make the mechanism located in the down, I used a couple of simple machines, a wheel and axle with a screw. For this, we need a couple of bearings, one bolt and 4 nuts. In the first picture you can see the order to assembly,but dont assembly yet! before place a couple of block mount between bearings (the greatest diameter must be outside). 582
Why using a threaded bolt? this because we are using the property of screw to fix the rope, and, get the capacity to move when we rotate the screw, convertir the circular motion to a linear one. Of course try to rotate the bolt with the hand could be a little bit harder, for solve that, we are using another simple machine, the lever. We can pick any stick for that job, just need only a little hole in the extreme to fit into the principal bolt. To fixed all the parts, just add a couple of supports between the block mounts,just like the last image of this section suggest.
Step 3: The Top Mechanism.
The top mechanism use exactly the same simple machines as the bottom, what the difference? this dont need a lever. But, this is the responsible to move the principal shaft. So, for solve this part, I decided to make a "spike" to the bolt, this can be possible with the help of much tools, you can use a Drill with stone, a sandpaper, abrasive file or a rotary tool. The final result must get the same shape like a flat screwdriver (not a small one). Finally, assembly the part like the bottom mechanism.
Step 4: The Tent.
Building this tent is the most easy part of this instructable. First, cut with the help of a scissors, the part of the plastic bag that is attached, as shown in the second picture. Later, pick a long round wood stick, I use one coming from an old broom. 215
