Principle of action

If ordinary swing doors open only in one direction, then the pendulum can move to any. The principle of their operation is based on the rotation around the axis with the same amplitude both in one and the other direction, and spontaneous return to the closed position. Therefore, these doors and got the name of the pendulum, or swinging.

Due to the presence of floor closers in the design of the pendulum doors (see Installing a door closer with your own hands), they can be fixed in the open position. This option is very convenient for residential premises and premises located inside heated buildings - for restaurants, cafes and boutiques in shopping centers.

Installation features

If you easily cope with the installation of conventional swing doors (see Installing Swing Interior Doors), it will not be much more difficult for you to install pendulum doors.

The main task will be to provide a vertical for the axis of rotation of the door, otherwise it will touch the upper transom or floor when moving. In addition, if the door is double, then you need to achieve a perfectly flat gap between the canvases.

Attention! Special attention should be paid to the installation and careful fixation of the floor closer, which accounts for a large load.

Some difficulties may arise during the installation of all-glass doors, in which assembly holes and cutouts for fixing accessories have already been made in production.

The choice of accessories

Fittings for swing doors include:

• Floor closer, which sinks to the floor. If there is no possibility for shtrobleniya floor, instead of the closer set the bottom axis.
• The upper axis, which is mounted either in the upper fitting of the stationary panel, or on the upper edge of the opening.
• Door fittings are special design mounts that play the role of hinges.
• Door handle
• Corner lock that secures the door to the upper transom fitting or to the floor.

The most important element of fittings are hinges for swing doors (see. Hinges for doors: their types and rules of choice). They differ in location on the door leaf: they can be attached to the side of the leaf or to its lower and upper corner.

Each type of loops has its advantages and disadvantages. In addition, hinges should be selected depending on the weight and dimensions of the door leaf.
