A safety window grid assembly includes a hollow housing, a rotating shaft rotatably disposed in the housing, a cord and a locking mechanism. The cord is retractable and extendable relative to the rotating shaft to convert between a retracted state and an extended state. The locking mechanism is disposed on the housing, and includes an operating member rotatable relative to the housing, a driving member connected co-rotatably to the operating member, and a locking member. The locking member is movable between a locking position where a portion of the cord is clamped between the rotating shaft and the locking member such that the cord is not movable, and an unlocking position where the locking member is spaced apart from the cord such that the cord is movable. |

1. A safety window grid assembly, comprising:
a housing being hollow and extending in a longitudinal direction; a rotating shaft rotatably disposed in said housing and having an axis perpendicular to the longitudinal direction; a cord that has a first end portion secured, to said rotating shaft and a second end portion, that is wound on said rotating shaft, and that is retractable and extendable relative to said rotating shaft to convert between a retracted state and an extended state, said cord being distributed in series along the axis of said rotating shaft when said cord is in the retracted state, said cord being partly unwound from said rotating shaft to form a grid structure when said cord is in the extended state, conversion of said cord between the retracted state and the extended state resulting in rotation of said rotating shaft in said housing; a locking mechanism disposed on said housing, and including
an operating member that is exposed from said housing and that is rotatable relative to said housing,a driving member that is disposed in said housing and that is connected co-rotatably to said operating member, anda locking member that is connected to said driving member such that said locking member is movable in the longitudinal direction between an unlocking position and a locking position relative to said rotating shaft in response to rotation of said driving member; andwherein when said locking member is in the locking position relative to said rotating shaft, a portion of said cord is clamped between said rotating shaft and said looking member such that said cord is not movable relative to said rotating shaft, and when said locking member is in the unlocking position relative to said rotating shaft, said locking member is spaced apart from said cord such that said cord is movable relative to said rotating shaft. |
