Dog (engineering) (original) (raw)
Il fermapersiana (talvolta detto anche fermaimposta) è un oggetto utile al mantenimento in posizione aperta della persiana. Esso si presenta sempre in coppia ed è fissato all'esterno della facciata, sul muro, normalmente in corrispondenza del bordo inferiore delle ante, e consiste in un pezzo di ferro basculante attorno ad un perno che si può alzare o ribassare e viene utilizzato appunto per fermare la persiana quando questa si trova in posizione aperta ed evitare che la stessa sbatta a causa di improvvise raffiche di vento.

| dbo:abstract | In engineering, a dog is a tool or part of a tool, such as a pawl, that prevents or imparts movement through physical engagement. It may hold another object in place by blocking it, clamping it, or otherwise obstructing its movement. Or it may couple various parts together so that they move in unison – the primary example of this being a flexible drive to mate two shafts in order to transmit torque. Some devices use dog clutches to lock together two spinning components. In a manual transmission, the dog clutches, or "dogs" lock the selected gear to the shaft it rotates on. Unless the dog is engaged, the gear will simply freewheel on the shaft. This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special engineering work when making it – it is not a simple part to make as it is not a simple bar or pipe, and the metal used in its construction is likely to be special rather than regular steel. There is potential for confusion as "dog tensioners" are levers that are named due to the shape of the lever appearing as a dog leg, as the lever is in a pantograph arrangement, or "dog trailers", which are named due to the use of multiple trailers for transporting animal cages. (en) Fensterladenhalter (engl.: „Shutter dogs“; franz.: „Crochet de volet“, „Arrêt de volet“) dienen zum Feststellen von geöffneten Fensterläden und zählen zu den Fensterbeschlägen. Fensterladenhalter gibt es in verschiedensten Ausführungen. Diese werden auch als Fensterladen-Feststeller, Feststeller, Ladenhalter, Ladenrückhalter, Ladenfeststeller, Klappladenhalter oder Schlagladenhalter bzw. nach der äußeren Form des beweglichen Teils auch als: Schäferkopf, Studentenkopf, Amazonenkopf, Frauenkopf, Ritterkopf, Männchen etc. bezeichnet. Eine mehrfache Funktion als Beschlag im Fensterbau haben sogenannte Vorreiber. Diese werden sowohl innen als auch außen verwendet, um Fenster, Fensterflügel oder Fensterläden auf- bzw. festzuhalten. Der Vorreiber als Fensterladenhalter ist dabei eine einfache, drehbare Metallfahne. Der Fensterladenhalter hat eine ähnliche Funktion wie der Sturmhaken und dient zur dauerhaften Offenhaltung der Fensterläden parallel zur Mauerkonstruktion. Der Sturmhaken als Fensterhaken kann jedoch zusätzlich noch mehrere verschiedene Positionen des Fensterladens, nicht nur parallel zum Mauerwerk, ermöglichen.
