Common applications include automobiles (where they are incorporated into the design of struts that support the weight of hatchback doors while they are open) and office chairs. They are also used in furniture, medical and aerospace applications. Much larger gas springs are found in machines that are used in industrial manufacturing (the press tooling industry), where the forces they are required to exert often range from 2500N to 400,000N (forty tonnes). Gas springs are manufactured in many varieties including: Return cylinder (no height adjustment) Auto-return cylinder with height adjustment If the internal plunger has a diaphragm which extends to the side of the gas tube, it will cease to move once an applied force is constant and will support a weight, like a normal spring.
If a fine hole exists in the plunger, however, it is termed a "slow-dampened spring" and can be used on heavy doors and windows. A gas spring designed for fast operation is termed a "quick gas spring" and is used in the manufacture of air guns and recoil buffers. Reducing the gas volume and hence increasing its internal pressure by means of a movable end stop, or allowing one tube to slide over another, can allow the characteristics of a gas spring to be adjusted during operation. The rod may be hollow by use of clever seals or may consist of multiple small-diameter rods. A small amount of oil is normally present. The gas may be introduced by a Schrader-type valve, using a lip seal around the rod and forcing it to allow gas in by external overpressure or a shuttling O-ring system. Gas springs of high pressure contain a very large amount of energy and can be used as a power pack. In emergency use the gas may be introduced via a gas generator cell, similar to those used in airbags.
Passive heave compensators features large gas springs. The stroke lengths can exceed 6 meter. A variety of features are available from various manufacturers: Adjustable push-in force via a local knob or remote via a bowden wire. Single touch release to allow full extension or the ability to lock it out. Extended stroke through telescoping mechanisms, usually composed of one rod and two cylinders (the smaller of the two cylinders actually acts as a second rod extending in and out of the larger cylinder). Vari-lift - intended for short production runs and prototypes, in applications where the exact force is important but hard to estimate in advance, such as lifting a lid slowly in a known time. In this case the cylinder is supplied filled to maximum design pressure, but equipped with a bleed port, to allow gas to be released once installed. The intention is that the design can be over-sprung, and then the pressure reduced in stages, to optimise behaviour. If too much gas is released, a new spring must be installed, and for large quantities, it is better to order a bespoke pressure setting from the maker.

Sitting still is not the same as paying attention. Research has shown that dynamic movement is good for the body and the mind. Regardless of the size of your home, it’s difficult to include in the decor every little object that you might or might not need at some point. It’s not practical either as it’s much simpler to just opt for fewer multipurpose pieces of furniture that will serve you just as well. This way you save space and money and you get to have everything you need right there in your small home.
Most people think that a chair is only what it appears to be, a place to sit on. But if you’re creative you can easily turn it into something else. For example, here we have four folding chairs that are mounted on the wall. When flat they just sit there. But when unfolded they become more than useful. The seat becomes a storage shelf and the base is great for hanging all sorts of things on.For those that either live alone or in a small space having too much furniture in the house is not exactly practical and it’s not necessary either. For such cases, the Aleph furniture is perfect. Designed by Gyuyub Jo, Aleph is a collection of pieces inspired by boxes. The collection consists of boxes, lids and wooden sticks that can be combined and reconfigured in many different ways, thus offering the maximum of efficiency and functionality while taking up minimum space.A similar collection is Badac. Created by Sang A Choi, the furniture was inspired by the Korean flat furniture called Pyung Sang.
Badac is a collection of eight pieces that can be used to create all sorts of different configurations. The pieces include two backrests, a coffee table, a lamp ad a shelf. The three seats are reversible and all the pieces are very versatile.Here’s another very interesting piece. This is “Madame est servie” and it’s a cheval mirror that can also become an ironing board. All you have to do is tilt it and lock it in place . It allows you to iron your clothes and then to admire them in the mirror. It’s a very interesting piece that combines two functions that are usually used consecutively.A bike that is stored inside the house is not exactly a way of saving space. It’s true that if you mount it on a wall on a bike rack it might not get in the way but that’s still not enough. However, if the bike rack can also be used for something else, then it’s a whole different situation. This Bike Shelf serves both as a rack and a shelf. It can be custom made to any bike size and from any type of wood.
{found on Knife & Saw}.It’s a collection of furniture pieces inspired by the Russian dolls that everyone knows about. The collection is composed of several versatile pieces that can be combined and configured in lots of different ways. But the best part is that the furniture pieces can be stored in one another. The most compact version takes up just 4 square meters. The pieces can be used to make a bed, a desk, a bookshelf, a coffee table, a dining table, a wardrobe, clothing drawers and seating for 12.Created by French designer Matali Crasset, this piece is very simple but also very flexible. One moment it’s a cozy, soft and relaxing pad to sleep on and the next it’s a seating area. It’s perfect for relaxing, chatting, reading, writing and other similar activities. It has an integrated table can be removed if needed. The pad can be folded according to your needs and transformed into a seating unit.Here’s another collection that is not only functional and versatile but also fun to look at.
This is the Flip furniture collection and it now also includes a chair shaped like a coffee cup. The idea behind this collection is that the pieces change function when flipped. The coffee cup can either be a low table or it can become an armchair or a chair with a low back.This is probably one of the most flexible and adaptable pieces you can ever find. It’s called “Land peel” and it was created by Japanese industrial design student Shin Yamashita. It’s basically just a flat mat. It’s made of three pieces and each panel can be lifted and it becomes either a table or a seat. It’s a perfect piece for activities such as lounging, studying, relaxing, reading or watching TV.How many of you wish they could have the space for a pool table in the house? Well, thanks to this piece, you will no longer have to worry about that. This is the “Fusion” table. It serves both as a dining table and as a pool table. It was created by Aramith and it’s a great multipurpose piece that allows you to have fun and to have a regular-looking dining area or living room by simply making a few changes.
Usually when we want to reach something that is stored all the way up in the top cabinet we take a chair. Even though it’s not exactly perfect and doesn’t give us a good view, it’s what we do because, let’s face it, who has a ladder in their home? Well, the reason why we don’t have ladders in our homes is because we have no place to store them. But this problem disappears when you get “The folding chair ladder”. As the name clearly suggests, this is a chair that, when unfolded, becomes a ladder.Another interesting example of a multifunctional piece of furniture would be the “Side chair”. Designed by Alexander Kneller, this is a modular piece of furniture that serves both as a chair and as a table. You can sit down and be comfortable and still have room near you for your laptop or for a glass, a plate, etc. There are two versions for each piece and one of them comes with an open lower area for storage.Lots of people like to read while relaxing on the sofa. It’s also common to have a small and cozy sofa in the reading corner.
But what if you could somehow combine this piece with another that is just as important: a bookcase? This is the Ransa sofa and it has a base that serves as book storage space. The sofa seems to be floating above the books and this is another nice feature that makes it stand out.In its most compact form, Multiplo resembles a brightly-colored cube that could be a table or an island. But that cube can be reconfigured in many different ways and it can become a bed, a sitting area or it can be taken apart into pieces and turned into a chair, table, nightstand or even a sofa. With Multiplo you don’t need anything else. Moreover, because of its design, colors and forms, it’s a perfect choice for the children’s playroom.It’s hard to imagine how a small piece shaped like a pyramid can become so many things. But “Cleo” shows us that surprises never end when you’re creative. Cleo is a modular sofa made of polyurethane foam. It was designed by Barbara Pece and it’s made of nice pieces.
