iii. A carriage configured to slide on the frame plate; and
iv. A window stay including a connecting element for connecting the carriage to the sash plate,
The carriage is:
a. Carriage body;
b. Engage with the frame plate at the latched position to limit sliding of the carriage on the frame plate, and disengage from the frame plate at the non-latched position to disengage the carriage on the frame plate A latching mechanism that allows sliding; and c. A window stay including one or more biasing elements integrally formed with the carriage body and configured to bias the latch mechanism to the latched position.

The carriage body is made of plastic and / or
The window stay according to claim 1, wherein the latch mechanism is made of metal.

In the first configuration of the window stay, the latch mechanism is in the latch position, and the carriage is in a first carriage position on the frame plate,
In the second configuration of the window stay, the latch mechanism is in the non-latching position, and the carriage can slide on the frame plate,
When the window stay is in the first configuration, the sash plate can move between a closed position and a partially open position with respect to the frame plate,
When the window stay is in the second configuration, the sash plate can move between the partially open position and the fully open position with respect to the frame plate, and / or
The closed position corresponds to a state in which a plane of the window sash is parallel to a plane of the window frame;
The partial open position corresponds to a state in which the plane of the window sash forms an angle of 10 to 60 degrees with the plane of the window frame,
The window stay according to claim 1 or 2, wherein the fully open position corresponds to a state in which the plane of the window sash forms an angle of 60 to 110 degrees with the plane of the window frame.

The carriage includes at least one flange configured to wrap around a longitudinal edge of the frame plate;
The carriage includes a metal insert;
And / or
The window stay according to any one of claims 1 to 3, wherein the metal insert extends into the at least one flange.

i. A first attachment portion and a second attachment portion configured to attach the frame plate to the window frame; and
ii. The first attachment portion and the second attachment portion extend between the first attachment portion and the second attachment portion, and are separated from the window frame by a gap in the installed window stay. The window stay according to claim 1, comprising a track portion that is lifted relative to.

The track portion is formed by stamping a generally elongated member so that the track portion is lifted relative to the first attachment portion and the second attachment portion. Window stay.

A first raised portion connects the first mounting portion to the track portion;
A second raised portion connects the second attachment portion to the track portion and / or
At least a portion of the first raised portion has a width transverse to the length of the frame plate that is narrower than the width of the track portion transverse to the length of the frame plate. The window stay according to 5.
