AI Technical Summary
Existing sliding windows lack a reliable mechanism to securely maintain any desired position without manual locking, leading to potential accidental movement.
A spring-loaded shaft connected to the window handle, with brake shoes that engage and disengage counterweight ropes to lock and unlock the window position based on handle orientation, ensuring automatic securing and releasing.
Enables the window to be securely maintained at any position with automatic locking and unlocking, enhancing safety and convenience by allowing simple handle operation.
Description
[0001] Sliding window with a braking device that secures the window in any position. The subject matter of the invention is a sliding window. with a braking device that secures the window in any position and engages when the window handle is grasped in order to move the window. It releases itself automatically, either upwards or downwards.
[0002] The essence of the invention consists in the fact that a spring-loaded shaft is rigidly connected to the window handle, the Both ends are designed as brake pads, which, when the handle is in a horizontal position, press against counterweight ropes and thereby to secure the window in its respective position, however, as soon as the handle is swung up or down while adjusting the window, also to swing to the side, thereby releasing the counterweight ropes that they were braking.
[0003] The drawing represents an exemplary embodiment of the invention, namely Fig. i shows a front view and Fig. 2 a Plan view of the locking device in partial section.
[0004] d is the sliding window, b are the hollowed window guides, c the counterweights running in these to the right and left of the window and d the two pull ropes, each about half their diameter in a cavity b which also serves to guide the counterweights The arranged, trough-shaped guide e runs. f is the handle rigidly connected to the axis of rotation g, which is held in a horizontal position by helical springs h. It is held in place as long as it remains untouched. The axis of rotation g terminates on both sides in a brake shoe i, which, in the position shown, rests against the ropes. They press and act as rope brakes, ensuring the window is securely fixed. At k, the rope d is attached to the upper window frame, at l to the weight c.
[0005] Now, when the handle f is turned to raise or lower the window, the shaft g also rotates, and the brake shoes i slide against it. immediately away from the rope d, so that the window becomes freely movable for adjustment. If the handle f is released again, then the parts f, g, i are by the springs h sitting on the shaft g are immediately returned to their original position, i.e., to the braking position, thereby automatically closing the window. is again determined.
[0006] As can be seen from this, simply turning the window handle is sufficient to immediately and automatically release the window from the locking position. And likewise, simply releasing the handle is enough to automatically and safely open the window to any desired height. to determine.
Claims
[0007] PATENT CLAIM: Sliding window with a braking device securing the window in any position, which engages when the window handle automatically releases for the purpose of moving the window upwards or downwards, characterized in that the window handle (f) The spring-loaded shaft (g) is in rigid connection, the ends of which are designed as brake shoes (i), which when horizontal position of the handle (f) presses against the counterweight ropes (d) and thereby secures the window in the respective position, whereas, as soon as the handle (f) is pivoted upwards or downwards when adjusting the window, also pivot to the side and thereby the ones they Release braked counterweight ropes (d).
