slide
A slide , also called a slide , is an inclined plane made of a smooth material, on which, thanks to the low friction and gravity, you can move down without any effort.
The structure is mostly intended for children to have fun (children's slide) and is primarily set up on playgrounds . There are also emergency slides in airplanes and isolated slides for adults in buildings, for example in the Google Office in Zurich and in the Technical University of Munich .
A children's slide usually consists of a ladder to climb up, which goes directly into the slide surface (trestle slide). If the slide is attached directly to the play equipment, it is called an add-on slide. The slide is limited on both sides by a railing-like side wall that protects against falling. The pleasure consists of sliding down on the sliding surface while sitting or lying down, the acceleration experienced and the subsequent landing on the ground, which is usually cushioned by sand or mulch . Slides differ in their height, incline and length of the slide surface and in design . Longer slides can contain curves.
term
Colloquially are called "slide" paths or streets indicated that due to heavy rain through the phenomenon of hydroplaning (aquaplaning) or by ice for pedestrians or vehicles only with an increased camber or risk of accidents are usable.
Slides that are not used by people but are used to transport materials are used, for example, in industrial production (e.g. chutes ). A raft or canoe slide is the colloquial term for the hydraulic construction of a boat lane .
Slide types
Slides are generally divided into three types of slide.
- The box slide (a straight floor with two upright side walls)
- It is the most common type of slide that is used primarily for playground slides. But this type of slide is also used for high-speed slides, the so-called free-fall slides, as these can usually only be guided in a straight line for safety reasons. The box slides are manufactured in three different designs: Slide bottom as an inclined plane, as an inclined plane with a wave or shaped as a brachistochrone (also known as a parabolic slide ).
- The half-shell slide (open trough)
- It is mostly used when additional curves are to be built. Due to the many possible combinations of curves and the associated slide length, longer slides are possible.
- The tunnel slide (closed tube)
- It represents an increase in the half-shell slide. This type of slide is mainly used for high exit heights, as it is a closed system and the user can therefore be prevented from falling out. Tunnel slides can also include the black-hole effect , in which users cannot see the course of the slide by darkening the tube, but can only feel it or guess it.
With a water slide , water also reduces the friction on the sliding surface between the sliding person and the sliding surface. Water slides can be found in swimming pools and outdoor pools .
In the past, slides made of wood were used by miners to slide on their ass leather to get into lower areas of the mine . Such slides can still be viewed and tried out in show mines, for example in Sondershausen or Berchtesgaden .
Application examples
In the city archives of the Swedish capital Stockholm there is a spiral slide that leads from the top floor through the open staircase to the basement. During the Second World War, it was used to move important files to the safe cellar before they were destroyed by bombs and fire.
The use of slides is also possible in event buildings. In the Graf-Ulrich-Bau in Grafenau-Döffingen there is a slide into the cellar bar.
