Abstract:
A locking mechanism is disclosed, which is installed in a movable rail of a window covering, and is passed through by a cord. The locking mechanism includes a locking unit and a pressing member, wherein the locking unit includes a stopping member which is movable between a first position and a second position. The stopping member is normally located at the first position to abut against the cord, which prevents the cord from moving relative to the locking mechanism, whereby to maintain the position of the movable rail. By pressing the pressing member, the stopping member is moved to the second position, where the stopping member no longer abuts against the cord. Therefore, when the movable rail is moved in a direction away from a fixed rail of the window covering, the cord can move relative to the locking mechanism. Whereby, the movable rail can be smoothly moved downward.

The holding sheet, is connected to the frame, and sequentially includes a connecting portion and a holding portion attached to the connecting portion, wherein the holding portion has an of :set relative to the connecting portion in the second direction.
Abstract:
A lifting device of a cordless covering includes a cord reel, a car, a driving module, a connecting cord, and a lifting cord. The cord reel has a cone section, and is pivoted on a headrail for free rotation. The car is received in the headrail for reciprocation. The driving module is received in the headrail to drive the cord reel to rotate in a predetermined direction. The connecting cord has opposite ends connected to the car and the cord reel, wherein the connecting cord is reeled in and out of the cone section of the cord reel when the cord reel rotates in different directions. The lifting cord runs around the car, and then extends out of the headrail to be fastened to a bottom rail. The cord reel and the driving module are helpful to precisely stop and bottom rail at any desired position.
Abstract:
A support structure for a roller for a shade includes a bracket, a plug and a limit member. The bracket is adapted to fix on a fixing member, and includes a connecting hole. The plug has one end connected to a shaft tube of the shade, and the other end thereof is inserted into the connecting hole of the bracket. The limit member is connected to the end of the plug, which is provided for being inserted into the connecting hole of the bracket, whereby the limiting member restrains the plug from detaching from the bracket. By the limit member, the connection of the bracket and the plug could be strengthened, so as to prevent the shade from falling off, whereby to enhance the safety of the support structure for the shade in use.
Abstract:
A connecting structure, which is located between a first object and a second object, includes a first engaging member and a second engaging member located between the first engaging member and the first object. The first engaging member is located between the second engaging member and the second object. The second engaging member has a thickness. When a distance between the first engaging member and the first object is less than or equal to said thickness, the first engaging member and the second engaging member are not movable relative to each other. When said distance is greater than said thickness, the first engaging member and the second engaging member can be moved in a direction relative to each other, moving the first object and the second object relative to each other as well. A covering device for an opening of a building is also disclosed, which includes said connecting structure.
Abstract:
A window covering system comprises a shell, a weight member, a covering material positioned between the shell and the weight member, a control device. The covering material comprises at least one ladder, multiple slats corresponding to the at least one ladder, and at least one lifting cord, wherein the lifting cord is connected between the shell and the weight member. The control device comprises a driving module, a releasing module, and an operation module that are connected to each other. The ladder is connected to the operation module, and the lifting cord is connected to the driving module, such that the operation module drives the ladder to tilt the slats, at the same time, the releasing module is driven by the operation module to remove restriction to the driving module, hence descending the weight member.
Abstract:
A window covering control assembly is used in a window covering system. The window covering control assembly comprises a driving module and a speed control module, and is provided in the shell, engaged to the weight element for simultaneous operation therewith. The driving module comprises a cord collecting assembly mounted in the shell. The cord collecting assembly is configured to operate in a first direction while a first driving force acting upon the cord collecting assembly such that the weight element descends away from the shell. The first driving force comprises at least a weight of the weight element. The speed control module is positioned corresponding to the driving module. A resistance force is selectively generated between the speed control module and the driving module, and this force reduces an operation speed of the cord collecting assembly in the first direction.
Abstract:
An apparatus for raising and lowering a covering member of a window covering includes a sliding base, a first biasing device, a connecting device, and a second biasing device. The sliding base is moved between a first position and a second position in a headrail. The first biasing device has two first biasing members to urge the sliding base toward the first position. The connecting device is moved between a third position and a fourth position in the headrail. The second biasing device has a second biasing member to urge the connecting device toward the third position. The second biasing member of the second biasing device is added at a middle of raising the covering member to help the covering member totally received close to or in the headrail.
Abstract:
A hanger for a sash of a window to detachably engage the sash with a rail of the window, and the hanger includes a pulley assembly and a restricting assembly. The pulley assembly has a base and a plurality of pulleys mounted on the base for rotation. The pulleys engage the rail so that the pulley assembly moves in the rail. The base is provided with a slot. The sash is provided with a rod. The rod engages the slot of the pulley assembly to engage the sash with the rail, and the rod leaves the slot via a lateral opening thereof while the covering rotates for a predetermined angle. At this time, the sash is disengaged with the rail to be moved off the window.
Abstract:
A slat of a window covering is disclosed, wherein the slat includes a core material and a covering layer covering thereon. The core material is substantially long, and a surface thereof could be divided into two side surfaces and a continuous surface, wherein one of the side surfaces is on one side of the core material in a longitudinal direction, and the other one of the side surfaces is on the other side of the core material in the longitudinal direction. The continuous surface connects the peripheries of the side surfaces. The continuous surface has at least one flat segment provided in the longitudinal direction. The covering layer covers the continuous surface, wherein the covering layer has a greater thickness on the at least one flat segment than on any other parts of the continuous surface.
