Hello, as you can likely see I'm new here. I'll be blunt and state off the bat that I am not a physicist or engineer in any manner. Math has never been my strength which is why I spent my university life within the social sciences. I've always had an admiration for those within the natural sciences and their ability to solve more "tangible" issues....which is why I am here. I need to enlist the help of some bright minds for a building project I'm doing in my new, but very small apartment. Essentially, my project involves the building of a wall bed/loft bed to optimize my use of space. I want this loft bed to be able to fold into the wall when it is not being used, but I also want it to be up high so that items underneath do not need to be moved when it is folded out. Since it is mounted up high, I am using an electric winch to close it. Think of a drawbridge where the bed is the bridge. It is a queen sized bed roughly 6.5 x 5 feet and opens horizontally. The winch itself doesn't provide any support, I am going to fasten chains at each end that reach full tension when the bed is level. The winch merely pulls it back up. Because it opens and closes, it makes it impractical to use the ceiling joists for support because the chains would be sticking out of the closed bed which closes into a box on the wall. My question then is, since the entire weight of the bed, building materials, myself, and my girlfriend would be supported on one wall, is this enough? I've calculated the materials generously at 300 pounds, and should probably alot 400 pounds for occupants, even though my girlfriend and I only weigh about 300 pounds cumulatively. The box that the bed folds into will be able to screw into 5 separate 2x4's (studs). The bed would extend about 6 feet outward, given that it is pivoting on hinges on the outer side of the box (which is one foot in diameter). My building materials would be red pine. I've attached a poor design sketch to this post. Again, I'm just wondering whether the wall will be able to hold this kind of weight with the outward pull. The chains on each side of the bed are fastened to the box, so as to distribute the weight over the 5 studs. I appreciate, any help you guys have to offer, and if anyone has questions about political science in return, I'd be more than happy to help :). Thank you kindly.
