An inward-opening type casement window having outward-opening pane and screen is provided. A primary screen is installed, via a first hinge, in a primary casement window frame so as to open inwardly. The primary screen is formed with a secondary frame. A secondary pane is installed, via a second hinge, in the secondary frame so as to open outwardly. A handle lock is installed between the primary screen and the primary casement window frame and between the secondary pane and the secondary frame. The handle lock is used to control opening and closing of the primary screen and the secondary pane. The pane can be swung out to facilitate ventilation, and the screen can prevent entry of insects and burglars. Moreover, the pane can be swung in together with the screen, thereby facilitating access, ventilation and cleansing.
An inward-opening type casement window having outward-opening pane and screen, comprising a primary casement window frame, a primary screen, a secondary pane and a handle lock, the primary screen being installed in the primary casement window frame via a first hinge so as to open inwardly, the primary screen being formed with a secondary frame, the secondary pane being installed in the secondary frame via a second hinge so as to open outwardly, the handle lock being installed between the primary screen and the primary casement window frame and between the secondary pane and the secondary frame, the handle lock being used to control opening and closing of the primary screen and the secondary pane, thereby enabling the entire casement window to be closed, or the secondary pane to be opened inwardly along with the primary screen, or the secondary pane to be separated from the primary screen and opened outwardly, or the secondary pane in an open state to be opened outwardly upon closing of the primary screen.
A double-control single-handle handle lock, comprising a handle, a transmission shaft, two transmission rods, a first locking point and a second locking point, the handle is mounted at an inner side of a primary screen, the transmission shaft and the transmission rods are mounted on the primary screen, the handle drives the transmission rods to slide up and down through the transmission shaft, the first locking point is fixed to one side of one of the transmission rods close to a primary casement window frame, the first locking point extends beyond the primary screen, the primary casement window frame is provided with a first locking block, the first locking block cooperates with the first locking point to lock or unlock the primary screen, the second locking point is fixed to one side of the other transmission rod close to a secondary frame, the second locking point extends beyond the secondary frame, a secondary pane is provided with a second locking block, the second locking block cooperates with the second locking point to lock or unlock the secondary pane, when the handle is not rotated, the first locking point and the second locking point are locked, when the handle is rotated leftward or rightward, the first locking point is driven to unlock but the second locking point remains locked or the second locking point and the first locking point are unlocked.
A novel friction hinge, comprising a hinge seat, a mounting rod, a fixing block, a slider, a first linkage rod, a second linkage rod and a third linkage rod, the hinge seat being mounted on a secondary frame, a head end of the hinge seat abutting against a non-opening end of the secondary frame, the fixing block being fixed in the hinge seat and located at a position close to the head end of the hinge seat, the slider being slidably disposed at a distal end of the hinge seat, the mounting rod is mounted on a secondary pane, one end of each of the first linkage rod and the second linkage rod being pivotally connected to the fixing block, one end of the third linkage rod being pivotally connected to the slider, another end of the first linkage rod being pivotally connected to a head end of the mounting rod, and another end of the second linkage rod being pivotally connected to a middle of the third linkage rod, another end of the third linkage rod being pivotally connected to a middle of the mounting rod.
An inward-opening type casement window having outward-opening pane and screen, comprising a primary screen, the primary screen having a T shape which is integrally formed or compositely formed, the primary screen having a primary horizontal frame, a primary vertical frame and a stop flange, the primary horizontal frame being located at an inner end of the primary vertical frame, a corner between the primary horizontal frame and the primary vertical frame being formed with a secondary frame for mounting a secondary pane in an outward-opening manner, an inner side of the primary horizontal frame being a screen mounting surface, the screen mounting surface being provided with an engaging strip, an inner side of the primary vertical frame being formed with a handle mounting portion, the inner end of the primary vertical frame extending in a direction opposite to the primary horizontal frame to form the stop flange of the primary screen to cooperate with a primary casement window frame, the primary vertical frame having a chamber for mounting a transmission shaft and a transmission rod of a handle lock, one side surface of the primary vertical frame, close to the primary casement window frame, and another side surface of the primary vertical frame, close to the secondary frame, being formed with mounting troughs for mounting first and second locking points or first and second locking blocks respectively, and the side surface of the primary vertical frame, close to the primary casement window frame, being further formed with another stop flange to cooperate with a sealing strip of the primary casement window frame.
