Bathroom door locks are used internally to protect privacy in a room within a property. They are generally used for the bathroom but can be used on any internal door to stop entrance. Bathroom locks do not have keys making locking and unlocking easy and fuss free.
A full bathroom mortice lock is a larger mechanism with a latch bolt at the top and a dead bolt further down (a rectangular shaped metal component). You will see a much longer metal plate (face plate) on the edge of the door. If you have a tubular mortice latch in the door, then you have a 'privacy' handle.
There are plenty of other door locks, and many fall within the seven categories of knob locks, deadbolt locks, cam locks, padlocks, mortise locks, smart locks and keypad locks. For example, lever handle door locks are used for inner doors and work much like knob locks.
A deadbolt is a locking mechanism that mounts much like a door knob. Most exterior doors are locked with a door knob, and also a deadbolt.
A latch bolt is the part of a door that keeps the door from coming open. In order to be a latch bolt, the item needs to slide into place. This separates the latch bolt from chain locks or hooks, where the fastening mechanism is simply placed in a holder.
The parts of a door handle include knobs/levers, latch mechanisms, strike plates, boxes and cylinder locks.
A lock is a part of a navigable waterway system that makes a water "channel" deep enough for vessels to use. The lock controls pool depths, for example in a lock and dam system across a waterway. The lock is a place where boats that travel up or down a river or canal can be moved to the next higher or lower level.
A sash lock works by using a lock, latch & handle mechanism meaning you can open and close the door without the worry about it locking behind you and you don't need the key each time. Available in a variety of security levels dependant on requirements, along with insurance approved mortice sash locks.
A privacy lock is a lock that is designed to allow someone to quickly lock a room from the inside for privacy. Such locks are most commonly seen on bedrooms and bathrooms, where people might not necessarily be concerned about security, but would have reasons to lock the door to keep people out.
While a privacy lock is appropriate for most bathrooms, you may find that, depending on your living situation (small children, individuals needing special care, etc.), you would prefer to have access to the bathroom at all times. When that's the case, a passage, or Hall & closet, lock is the desired function.
Privacy door knobs are designed for interior doors. They can be locked and unlocked by an emergency key on the outside, and a push-button or turn button from the inside. This type of knob is designed for privacy instead of security.
Bathroom locks are subject to all the same regulations as every other piece of door ironmongery.
PASSAGE SETS are used where doors do not need to lock. There is no key cylinder and no means to lock a passage set. PRIVACY SETS are often used for single-occupant restrooms or dressing rooms.
Privacy knobs have a locking system but do not require keys. If you want to unlock the door, you can use a privacy emergency key instead. For passage knobs, you cannot lock them. The knob is purely for easy access to another room.
The Panama Canal locks (Spanish: Esclusas del Canal de Panamá) are a lock system that lifts ships up 85 feet (26 metres) to the main elevation of the Panama Canal and down again.
The purpose of the locks and dams is to create a series of steps which river tows and other boats either climb or descend as they travel upstream or downstream.
The Erie Canal is a 363-mile waterway that connects the Great Lakes with the Atlantic Ocean via the Hudson River in upstate New York. The channel, which traverses New York state from Albany to Buffalo on Lake Erie, was considered an engineering marvel when it first opened in 1825.
Lever A flat shaped movable detainer in a lock, usually for the purpose of providing security and differs. The lever(s) in a lock have to be actually moved by the key to operate the lock. The belly of the lever is cut away to various depths to provide different combinations.
For example, a doorknob is an example of a wheel and axle in which the knob itself acts as the wheel, and the shaft of the lockset acts like the axle. It is important to note that the “wheel” in this scenario does not have to act like a wheel at all, but is a rounded object that rotates.
The Bore hole is the large diameter hole where the door knob is mounted. The standard sized bore hole is 2 1/8" in diameter. Through the edge of the door there is a 1" cross bore that extends from the edge of the door through the bore hole. This cross bore is where the latch is installed.
Passage door knobs are similar to dummy door knobs. They don't lock but are used to open doors and go between rooms. Passage door knobs are ideal for interior hallways, closets and other rooms that don't need privacy locks. They're also called unkeyed knobs.
The more common spring bolt lock uses a spring to hold the bolt in place, allowing retraction by applying force to the bolt itself. A deadbolt can therefore make a door more resistant to entry without the correct key, as well as make the door more resistant to forced entry.
Each lock type carries certain advantages; for example, a latchbolt will lock automatically, while most deadbolts require manual locking. On the other hand, deadbolts are widely considered to be stronger and harder to pick than latchbolts.
