Between technical aspects and aesthetic considerations, whether you are installing a handle for an interior door or an exterior door, hinged or sliding, understanding the available options in terms of locks, bolts, and door hardware in general will be very useful for making your choice. Discover the complete guide to everything you need to know about privacy handles and their accessories.

What is a privacy handle?

A privacy handle is an integrated closing system that allows a door to be locked without the need for a key. It commonly consists of a handle combined with a privacy lock. 

Privacy handles are used to fit interior doors, often those of bathrooms or toilets, rooms for which functionality and cleanliness are the priority.

Description of the privacy lock mechanism

A privacy lock is a simple closing system designed to block a door from opening from the inside. It is commonly found on bathroom or toilet doors, where privacy is the priority. Here is a detailed explanation of its mechanism:

1. The main components of the privacy lock

 The privacy lock is made up of several functional elements:

* The rotary knob or latch: located on the inner face of the door, it allows the user to lock or unlock the door by a simple rotation or sliding action.

* The bolt: a moving metal part that engages in the strike plate fixed to the frame to hold the door in the closed position. Depending on the model, it may be a deadbolt or a half-turn bolt.

* The strike plate: fixed to the door frame (jamb), it receives the bolt and enables locking.

* The connecting rod: transmits the movement of the rotary knob to the bolt, engaging or withdrawing it from the strike plate.

* The free/occupied indicator (optional): present on certain models, it visually displays the status of the door (green for "free", red for "occupied").

* The external unlocking device: often a push button, a screwdriver hole, or a coin slot, it allows the door to be opened from the outside in an emergency.

2. How the mechanism works

* Interior locking

When the user turns the rotary knob or operates the latch, the connecting rod pushes the bolt forward.

The bolt engages in the strike plate, thereby preventing the door from opening.

* Interior unlocking

By turning the knob in the opposite direction, the bolt is withdrawn from the strike plate, thereby releasing the door.

This action is smooth and requires no significant effort.

* External unlocking

In an emergency, the emergency release device allows the bolt to be operated directly from the outside. For example, a screwdriver or a coin can be inserted into the slot to turn the mechanism and release the bolt.

3. Variants of privacy locks

* Integrated rotary knob lock: the most common type, this model offers intuitive operation. This type of lock is fitted with a rotary knob on the inner rose, allowing the door to be locked simply. Easy to install and compatible with reversible handles, it is perfect for interior bathroom and family toilet doors.

* Sliding latch lock: simpler, it suits doors where installing a rotary mechanism is difficult.

* WC lock with free/occupied indicator: this system features an indicator visible on the outer rose, often used with a mortice lock or a recessed mechanism. Very practical for public or family bathrooms, it instantly shows the status of the door, providing clear signage to avoid attempting to open the door when it is occupied.

This lock is ideal for offices or homes welcoming guests.

* Lock integrated into a handle furniture set: combines door handle and lock in a single unit for a streamlined design.

* Lock with external unlocking: a lock with a small hole allowing a screwdriver or tool to be inserted to unlock the door in an emergency. Safe for families, particularly with children or people with reduced mobility (PRM), it is also ideal for shared or family dwellings.

Advantages of the mechanism

* Ease of use: easy to operate for both adults and children.

* Quick installation: little tooling required for surface-mounted or integrated models (a simple screwdriver is sufficient in most cases).

* Security: allows privacy to be maintained whilst offering an emergency unlocking solution.

This mechanism, although relatively basic, is ideal for interior doors requiring occasional and practical locking. For a front door or one requiring enhanced security, other systems such as multipoint or cylinder locks are recommended.

Technical compatibility criteria

Before opting for a privacy lock, please check that your new handle is suited to your door and your needs!

Type of door 

* Interior door: ensure that the chosen privacy lock is compatible with a standard interior door or a sliding door. For example, some models require a specific mechanism for pocket doors.

* Front door or landing door: if you are looking for a lock for a landing or exterior door, opt for a more robust model, although a privacy lock is not ideal for this type of door.

The lock backset 

The backset is the distance between the centre of the handle (axis of rotation of the lever) and the centre of the cylinder or lock. Check that your lock or furniture is compatible with the standard dimensions of your door. Common backsets are 70 mm or 195 mm for privacy handles.

The type of strike plate and bolt 

Depending on your door, you will need to choose between a deadbolt lock (more secure) or a half-turn bolt lock, ideal for quick opening and closing. Ensure that the strike plate is suited to the frame of your door.

Door and lock materials 

A solid wood, aluminium, or glass door requires appropriate fixings. For example, a brass or brushed stainless steel lock is perfect for a design wooden door, while a stainless steel model is perfectly suited to a metal door.

Reversibility of the lock 

Check whether the lock is reversible, meaning it can be used on a left-opening or right-opening door. This simplifies installation and is suitable for interior doors.

PRM Standards 

If the lock is intended for a space accessible to people with reduced mobility, choose a model complying with PRM standards. These models allow easy operation and are often fitted with a simplified external unlocking mechanism.

Rose compatibility and finishes 

If you already have a door handle installed, check that the privacy lock is compatible with the existing rose or escutcheon plate. The finishes (chrome, matt black, polished brass, etc.) should also be coordinated for an aesthetic result.

Drilling dimensions and faceplate 

For a perfect installation, ensure that the door drilling corresponds to the chosen model. If you are replacing an existing lock, the faceplate dimensions must match to avoid any carpentry adjustments.

Is the privacy lock suitable for children?

When it comes to children, using a privacy lock on bathroom or toilet doors has both advantages and precautions to consider:

Advantages of the privacy lock for children 

* Ease of use: young children can easily understand how to use a rotary lock or a privacy knob. This allows them to close the door for privacy without handling a key.

* Enhanced safety in an emergency: most privacy locks are designed to allow emergency unlocking from the outside, often with a simple tool such as a flat-head screwdriver or a small metal tool. This ensures that if a child becomes locked in, an adult can open the door quickly.

Precautions to take 

* Accessibility of the emergency release: ensure that the external unlocking device is easily accessible to adults when needed. This may be a dedicated tool or simply a suitable metal rod, to be kept nearby.

* Children's education: teach children how to use the privacy lock correctly and stress that it must not be used as a game. Children should know that they can ask for help if they find themselves locked in or unable to open the door.

* Appropriate age: for very young children (under 4 years old), it is recommended to opt for locks that do not risk trapping them without an easy way out. Some parents even prefer high-mounted latches to restrict access for toddlers.

A well-chosen and correctly installed privacy lock can provide security and privacy for children whilst allowing parents to remain in control and respond quickly if necessary.
