  • Patent number: 6434887
    Abstract: A window stay is provided for mounting a window in a window frame. The window stay comprises a bar member for connection to the window, a track member for connection to the window frame, a slide member slidably mounted on the track member, and a pair of arms for moving the bar member to a closed position and to an open position. The pair of arms comprise a first arm connecting the track member to the bar member and a second arm connecting the bar member to the slide member so that the bar member overlies the track member in the closed position and is slidingly moved away from the track member in the open position. A projection is disposed on the bar member and has a side surface extending in a longitudinal direction of the bar member. An insert groove is formed at an end portion of the track member for receiving the projection when the bar member is in the closed position.

  • Patent number: 5383303
    Abstract: A window constructed such that a window sash is slidable upwardly and downwardly along a side jamb of a window, and may be inclined relative to the side jamb. The window sash is hung by a counterbalance and held at a selected desired position. The counterbalance is provided with a coiled torsion spring which counter balances the window sash, and the torsion force of the torsion spring can be adjusted. Adjusting mechanism is provided with a rotatable adjusting shaft for adjusting the torsion force of the torsion spring, a braking member for applying braking force to the adjusting shaft to prevent the rotation of the adjusting shaft, and a cam face for urging the braking member against the adjusting shaft to brake it or release it.
