This post is inspired from the last one, and the difficulty I have with understand the workings and fitting of a hinge. Mainly for me to refer to, I started by an internet search ‘What is hinge’ …..
Hinge, a Dating App, Introduces Friends of Friends. … That is the premise behind Hinge, the next mobile matchmaking app that is catching on with urban millennials. At first glance, it looks very much like Tinder. But instead of random strangers, Hinge matches only users who share Facebook friends……
Oops my search should have been ‘What is a hinge’ …
A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of flexible material or of moving components…. [Wikipedia]
The hinge I have used is called a butt hinge.
I went onto the ‘DIY World‘ site that describes this type of hinge … ‘Looking at the 75mm hinge it appears at first glance that the two flaps are identical, but on closer examination, a slight difference can be seen between them. The knuckle which is wrapped around the pivot pin is made up of five segments from the two flaps, with one flap forming the top, middle and bottom segments, while the other forms the other two. The flap that forms the two portions also has slight gaps between it and the knuckle at the top middle and bottom. This flap with the two portions wrapped around the pivot pin is the flap that is fitted to the door.’
Well there we go, why do I find a simple hinge so complicated?
This is my hinge with its flaps open around the pivot pin.
This is my hinge with its flaps closed around the pivot pin.
This is my hinge turning its flaps on the pivot pin, this way it does not close all the way but stops at an angle.
This is my hinge with one of its flaps attatched to a piece of wood with screws. [A short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.]
This is my hinge in place, with both flaps attached with screws, enabling it to rotate around the pivot pin.
My door will have a gap in it as I have attached it using the original screw holes, I could have mounted it against the edge thus giving it a smaller gap. As the area of wood which the screws would have to go in is not very wide, it was better this way.
Do I understand the workings of a hinge better, yes at the moment, until the next time …………..
