A hinge is an object made up of two pieces that move together to join two elements.
A hinge is an object formed by two pieces that have a common axis , which allows them to move together to join two elements. Also called a hinge or hinge , this hardware makes it possible to open and close windows and doors .
There are multiple types of hinges, of various materials and shapes and with numerous different uses. There are bronze , zinc , steel and plastic hinges, for example, that allow an opening of 180° or less and are installed with screws or other methods.
Door and window hinges
Doors usually have two or three hinges that facilitate their movement. This way a person can open or close the door, moving it closer or further away from the frame as desired. The usual thing is to move the door from its handle , latch , handle or knob : the force applied makes the hinge fulfill its function.
Windows have a similar function. Like doors, they usually have hinges that make their rotation movement possible and, therefore, their opening and closing.
In the case of sliding or sliding doors and windows , they do not have hinges since they work in a different way. When sliding, doors and windows move on an axis forward and backward or right and left, but not in and out.
Doors and windows are usually hinged.
How to lubricate them
When a hinge begins to squeak, that is, to emit a sharp, stinging noise due to having lost its lubrication, its use begins to cause discomfort, especially at night. For this reason, it is very important to keep the hinges on all doors and windows in good condition.
The steps to lubricate a hinge are few and simple, and do not require the use of very specific tools . The first step is to buy the most suitable lubricant. Needless to say, we should not skimp on expenses with this product, since considerable savings may lead to the need to apply it very frequently, or it may not even give the desired result.
Some of the most recommended hinge lubricants are silicone ones (which are sold in aerosol and are very easy to apply), lithium grease (effectively resists dust and is available in almost all auto parts stores) and edible oils (ideal to get out of a pinch, but much less effective than the previous two).
Next, it is necessary to remove the pin from the hinge by turning it counterclockwise, either by hand or with tweezers , and remove all traces of dust and dirt, since these are the causes of malfunctions and noise. If it is rusted, then an inhibitor product may be necessary to loosen it. It is time to apply the lubricant, both on the pin and in the gaps of the hinge itself.
From this point, it is a matter of replacing the plug and checking if the squeaking continues; If so, then we will have to remove it and lubricate it again, and so on until we achieve the result we are looking for. Excess product can be wiped off with a paper towel or cloth rag.
