A couch unfolded into a bed. A sofa bed or sofa-bed (in the US often called a sofabed, hide-a-bed, bed-couch, sleeper-sofa, or pullout sofa) is a multifunctional furniture typically consisting of a sofa or couch that, underneath its seating cushions, hides a metal frame and thin mattress that can be unfolded or opened up to make a bed.
Another resemblance that foldforming has is the paper fold technique known as "origami". The process of folding and unfolding a flat material is seen in both metal foldforming and papering folding origami. Many of the principles and issues that come with the folding and unfolding process can be seen in origami and foldforming. [7]
The top two futons in each stack are covered in white fitted sheets, matching the pillowslips. A futon is a traditional Japanese style of bedding. A complete futon set consists of a mattress (敷き布団, shikibuton, lit. "spreading futon") and a duvet (掛け布団, kakebuton, lit. "covering futon"). [1]
In folding, clamping beams hold the longer side of the sheet. The beam rises and folds the sheet around a bend profile. The bend beam can move the sheet up or down, permitting the fabricating of parts with positive and negative bend angles. The resulting bend angle is influenced by the folding angle of the beam, tool geometry, and material ...
The metal section frame was invented by picture framer Donald P. Herbert (1926–1982) in the late 1960s. The frame was designed to fill a void within the framing industry. The concept followed Herbert's attendance at a museum conference in 1967 in Toronto where he met with Dr. Harold Joachim (1909–1983), at that time the Curator of the ...
The Miura fold is a form of rigid origami, meaning that the fold can be carried out by a continuous motion in which, at each step, each parallelogram is completely flat. This property allows it to be used to fold surfaces made of rigid materials, making it distinct from the Kresling fold and Yoshimura fold which cannot be rigidly folded and ...
The metal used by the Egyptians for woodworking tools was originally copper and eventually, after 2000 BC bronze as iron working was unknown until much later. [ 2 ] Commonly used woodworking tools included axes , adzes , chisels , pull saws , and bow drills .
A brake is a metalworking machine that allows the bending of sheet metal. A cornice brake only allows for simple bends and creases, while a box-and-pan brake also allows one to form box and pan shapes. It is also known as a bending machine or bending brake or in Britain as a sheet metal folder or just a folder.
