Parts of a Door Handle

Post #1 autor: mingtinan624 » 24 cze 2022, 03:17

Parts of a Door Handle
Most people turn door handles every day and never even give a second thought to the parts of a door handle until they need or choose to replace part or all of the handle. If you're going to DIY your door hardware, it can be useful to know more about door handle components first. The parts of a door handle include knobs/levers, latch mechanisms, strike plates, boxes and cylinder locks.

The most obviously noticeable part of the door handle is the knob or lever that actually allows the door to open. Knobs are generally round, although they may come in other shapes, and they open the door by turning, whereas levers (also called lever handles) open the door by pushing down. While it's pretty hard to install a door handle in the wrong direction, it's important to pay attention to the direction of a lever when installing one.

While not the most important of door knob parts, a rosette is the plate behind the door handle or lever. While the rosettes in most homes are simple metal pieces, they can be elegantly detailed, and some door handles, particularly those with vintage designs, don't have a rosette at all.

The Latch Mechanism

Perhaps the most important of all door handle parts is the latch mechanism. This is the spring-loaded piece that protrudes past the door, keeping the door closed. While most latch mechanisms use a retracting tubular latch mechanism that goes in when the handle is turned, some doors, like closets, use a ball latch. A ball latch doesn't retract when the handle is turned but instead is simply pushed open or closed in order to catch it on the specially indented strike plate.

The latch itself is generally fitted to the door with a mortise plate, which provides additional security and makes installation more easy so the latch is properly situated in the door in order to catch on the door frame when the door is closed. Additionally, the mortise plate makes the latch mechanism look much more attractive than simply having a floating latch stick out the side of the door.

When the door is pushed closed, the strike plate is the metal piece that the latch is pushed into on the door jam. The box is the hole where the latch fits in, which may or may not be fitted with a strike plate.

Ball latches require a special, shallow strike plate, but most retracting tubular latches don't require a strike plate because they will still retract and go into the box when pushed against a door frame. That being said, strike plates make the door function more smoothly, look more attractive and protect the door frame from damage caused by repeatedly being pressed on by the latch.

Push Pull Door Handle
The initial idea of push-pull door-handle is to ease opening of the door simply by mounting the push-pull door-handle, without any interference with the door, lock or doorjamb. installation is simple, the same as classic handle.
classical opening of the door takes place by pressing the handle and then either pulling or pushing the door away. push-pull door-handle does not require vertical pressure on the handle, since it is replaced by the movement of handle in the direction of opening the door, thereby opening is much smoother and more comfortable.
the procedure is the same, when we are closing the door. handle is pulled or pushed in the direction of movement of the door, so the door closes.
this is particulary usefull, when our hands are not free (if we are carrying different objects, pushing wheelchair or bed, or we are limited by disability). it is already sufficient that we lean with the body to the handle and push the door.
it would also be possible to use this concept on fire doors, where push-pull door-handle could replace special hardware, that lets you push-open the door.
it is also important that push-pull door-handle preserves function of the classic handle whit a vertical movement.

structure, function:

the handle consists of two parts, internal, technical part, which is placed in the stem of door-handle, and holder, which can be designed in many different ways.
handle is classicaly mounted on the door, with no additional interventions to the door or lock.
the mechanism that enables innovative action is robust and assembled from a small number of parts. it consists of a central rotating axis, cubical framework for mounting other components, two leverages for trigerring a rotation of axis, and an outer casing.
push-pull door-handle works by pushing or pulling handle, which activates individual leverage and triggers the rotation of the axis. this opens the lock.
the spring of the lock returns the handle to its original position.

design:

the handle is divided into two parts, the mechanism for opening, which is built in stem of the door-handle, and holder. the concept of push-pull handle allows the application of different types of handles, making it easier to use in different ambience.
grip of the handle is shaped accordingly to its application and technical requirements.
the presented design is minimalistic, robust and easy to manufacture.

In its robustness it hides well planned ergonomics, enables good hand position at all three possible manipulations with push-pull door-handle: press down, pull towards you, and pushing away.

Everything You Need to Know About Patio Door Handles

Lever handles, also known as door levers, are the most common type of door handle used in residential houses and commercial and public buildings. Lever handles can be split into two groups: lever handles on backplate and lever handles on rose.

Lever handles on a backplate are traditional door handles which sit on a backplate. These can have three operating mechanisms, including lever lock, lever bathroom and lever latch.

Lever lock.

This mechanism features a keyhole to operate the door handle, providing security and privacy and is often combined with a mortice lock.

Lever bathroom.

Often used on bathroom and bedroom doors, where some privacy is needed. This mechanism features a thumb turn lock, which can be locked and unlocked easily from the inside by turning the snib but can also be unlocked from the outside by turning the coin slot, in case of an emergency.

Lever latch.

Pros and Cons of Stainless Steel Handles
Stainless steel is one of the most common materials in which handles are made. Whether you’re shopping for a ball handle, a pull handle, adjustable handles, or crank handles, you can probably find it in stainless steel. Stainless steel handles have pros and cons Below is a breakdown of some of the pros and cons of stainless steel handles.
Pro: Corrosion Resistance

It shouldn’t come as a surprise to learn that stainless steel handles are resistant to corrosion. Stainless steel is an iron alloy that contains chromium (as well as nickel in some types of stainless steel). The presence of this chromium protects it from corrosion. You can use a stainless steel handle in a humid environment without fear of it rusting or corroding.
Pro: Aesthetics

Most people will agree that stainless steel handles look nice. They offer a consistent bright and shiny appearance. Other types of handles often have a dull or matte appearance, resulting in a lower level of aesthetics. Stainless steel handles offer a higher level of aesthetics thanks to their bright and shiny appearance that’s consistent throughout.

Pro: Nonmagnetic

Stainless steel handles are also nonmagnetic. Why does this matter? Some applications require the use of nonmagnetic handles. If a handle produces a magnetic field, it may attract other magnetic objects nearby. Alternatively, magnetic handles may damage certain electronics. Stainless steel handles are nonmagnetic, though, so they won’t cause these or other problems.

Con: Cost

While stainless steel handles aren’t particularly expensive, they tend to cost more than handles made of other materials. You can find handles made of plastic and other similar synthetic materials. These handles typically cost less than their stainless steel counterparts.

Con: Weight

Weight is a potential downside of stainless steel handles. Stainless steel handles typically weigh more than those made of other materials. They are denser and heavier than most other materials, so they usually weigh more. If weight is a concern, you may want to choose a handle made of a different material.
