Window corner guard and window corner protection method

A window corner protection method, for protecting a window corner of a window sash to prevent impact injuries, comprising:

• providing a window corner guard comprising a base and a corner guard;
• one of a shaft column and a shaft hole being provided on the base, the other being provided on the corner guard, and the shaft column being arranged in the shaft hole in a penetrating manner;
• a size of the shaft hole in a first direction perpendicular to a length direction of the shaft column being greater than a size of the shaft column, and a first pivot position and a second pivot position arranged at a predetermined distance apart being formed in the first direction;
• and a rotary locking assembly acting between the base and the corner guard to lock or unlock rotation of the corner guard;
• fixing the base to a surface of the window sash near the window corner;
• to protect the window corner, rotating the corner guard to cover the window corner, and then displacing the corner guard in the first direction to displace the shaft column to the first pivot position, and the rotary locking assembly locking the rotation of the corner guard to be kept locked;
• and
• to release the protection, reversely displacing the corner guard in the first direction to displace the shaft column from the first pivot position to the second pivot position, unlocking the rotary locking assembly, and restoring the corner guard to be rotatable to form an unlocked state.

A window corner guard, configured to be mounted to a window corner of a window sash to prevent impact injuries, comprising:

• a base configured to be fixed to the window sash near the window corner;
• and
• a corner guard capable of covering the window corner and being locked for rotation by a rotary locking assembly to prevent impact injuries, and also capable of unlocking the rotary locking assembly to transition to a freely rotatable state;
• wherein,
• the corner guard is pivotably connected to the base by a shaft column, and is formed with a first pivot position and a second pivot position, the corner guard is also movably displaced relative to the base along a first direction perpendicular to a direction in which the shaft column extends, and the second pivot position is spaced apart by a predetermined distance in the first direction relative to the first pivot position;
• when the shaft column is in the first pivot position, the rotary locking assembly locks the rotation of the corner guard to form a locked state;
• the corner guard is driven to movably displace in the first direction so that the shaft column is displaced from the first pivot position to the second pivot position, and the rotary locking assembly is unlocked to transition to the freely rotatable unlocked state.
