Eyre and William Spottiswoode. p.111. OCLC 54199007. A door closer is a mechanical device that regulates the speed and action of a door’s swing. [1] Manual closers store the force used to open the door in some type of spring and reuse it to close the door. Automatic types use electricity to regulate door swing behavior. What sets pneumatic door openers apart from other automatic door openers is that they use air pressure instead of electronics to produce the energy to move a door. This has a number of highly useful applications which means that Automatic Access can provide solutions for pretty much any context where an automatic door is required.electromagnetic device.

Door closers are widely used in both residential and non-residential settings. At home, they are most commonly found on screen and storm doors. They are also used in numerous applications in commercial, industrial, institutional, and public facilities from libraries and schools to museums and airports. Door closers also play a role in maintaining desired interior temperatures, reducing air movement in and out of conditioned space. This article needs additional citations for verification.

The shoe door closer, known as a heel spring, [35] is housed entirely in the 'heel' of the door, inside a shoe. This shoe looks very much like the shoe used in conjunction with floor springs. Spring hinge uses a spring mounted in a hinge and is integral to its design. The spring can be either visible or hidden within a tube and can be found more commonly on interior doors. When used on doors that open both ways they are known as double action spring hinges.Some of the key features of fire door closers include adjustable latching and closing speed . This gives you the ability to adjust the door closer to specific fire code requirements, ensuring that the door closes at the correct rate to provide maximum protection. Tobias, Scott (2015-04-13). Illustrated Guide to Door Hardware: Design, Specification, Selection. John Wiley & Sons. p.323. ISBN 9781118112618. Controlled closers” use adjustable hydraulic valves to variously regulate the door’s opening and closing speed, latch speed, and delayed action return. These allow setting of the “sweep speed” (the rate which the door travels along the majority of its closure, the sole closing setting on basic closers); the “latch speed” (the rate in the last 10 to 15 degrees of closing arc, allowing it to be set faster than the "sweep" to ensure proper latch closure); “delayed action” (which slows sweep speed dramatically for roughly the first half of its range, allowing more time for passage), [27] and opening speed (preventing a door from being opened too fast, a useful feature in crowded environments, and those where the young, old, or infirm may be present). It is also particularly well-suited to exterior doors where there is a danger of wind catching and blowing them open, potentially harming the door, nearby objects, people, or pets. A self-closing hinge combines door closers and spring hinges with an optional hold open feature into one component. These closer hinges eliminate the visual and physical clutter of using additional devices, as well as reduce maintenance problems associated with overhead and in-floor door closers. They are especially useful where other types of closers are difficult to use. The most durable self-closing hinge can handle doors up to 440 lb. https://www.britishnewspaperarchive.co.uk/viewer/bl/0000254/17381221/006/0003– via British Newspaper Archive. {{ cite news}}: Missing or empty |title= ( help)
