Abstract: A rotary tool assembly includes a rotary tool having a body with a working end and a rear end, a motor disposed within the body, and a drive shaft rotatably driven by the motor. A base of the rotary tool assembly includes a battery receptacle configured to receive a battery pack and a stand for supporting the rotary tool when the rotary tool is not in use. The stand includes two arms defining a tool receptacle therebetween in which the rotary tool is supported. A power cord extends between the base and the rotary tool to transfer electric power from the base to the rotary tool to selectively power the motor. The battery pack is received in the battery receptacle for form a foot of the base.

Abstract: A window blind includes a first rail, a second rail, a plurality of slats, a modulation mechanism, and an adjustment unit. The modulation mechanism includes a modulation shaft which can drive two warps of the ladder tape to make a relative movement in a vertical direction, whereby to modulate the slats to turn. When the slats are turned from a first position to a second position, the adjustment unit moves a rear cord which is used to move the second rail, whereby to change a length of a segment of the rear cord between a bottom edge of the first rail and a top edge of the second rail. In this way, the second rail could be turned along with the slats which are driven by the modulation shaft, and the problem of light leakage could be improved.

Abstract: A sunshade structure is disclosed, which is installed on a window frame, and includes a main shading member and an auxiliary shading member. The main shading member is a window covering having a headrail, a bottom rail, and a covering assembly which connects the headrail and the bottom rail. The auxiliary shading member includes at least one movable plate. When the bottom rail is located at a first position away from the headrail, the at least one movable plate approaches the covering assembly to cover a gap formed between the covering assembly and a lateral side of the window frame; when the bottom rail leaves the first position and moves toward a second position near the headrail, the at least one movable plate pivots to stop blocking out light from outside.

Abstract: A window covering and tighteners of the window covering are provided, wherein each of the tighteners is a closed frame having an inner surface and an outer surface. The space surrounded by the inner surface forms a through hole and a gap which are communicated with each other, wherein the through hole allows a cord, which moves a bottom rail relative to a headrail of the window covering, to pass therethrough, and the width of the gap is less than the diameter of the cord. Whereby, if the cord is accidentally pulled away from the shades laterally or horizontally, the cord quickly and smoothly enters the gap to be tightly bitten therein. The cord is hence stopped from being further pulled outwardly to form a hazardous loop which may cause serious injuries to users.

Abstract: A cord locker of a roman shade includes a base, a rotary member and a connector. The connector is fixed to a shade member of the roman shade, and the base is connected to the connector. The rotary member is pivoted on the base to let the cord passes through between the rotary member and the base. While the cord is pulled, it will turn the rotary member and make the rotary member press the cord onto the base. As a result, the cord is unable to be pulled anymore in a very short time.

Abstract: A roll-up apparatus, which provides a unidirectional resistance, includes an outer barrel, an inner barrel, damping oil, a clutch device, and a driving device. The outer and the inner barrels each has a concentric-circle structure therein. The inner barrel has first ratchet teeth. The outer barrel is fitted to the inner barrel, and the concentric-circle structures are engaged. The damping oil is received in a space between the concentric-circle structures. The clutch device has second ratchet teeth to disengage and engage the first ratchet teeth of the inner barrel when the clutch device is moved to a first position and a second position. The driving device moves the clutch device between the first position and the second position.

Abstract: A cord locker includes a plate with a through hole and a sidewall connected to an edge of the plate. The sidewall has at least a slot. The cord locker is incorporated in a length adjusting mechanism of a window covering, in which a cord has an end fixed to a top rail of the window covering and the other end passing through the through hole of the plate via a bottom of the cord locker, and then the cord is turned to pass through the slot of the sidewall, and then cross the plate and turn back to pass through the slot for fastening the cord and adjusting the length of the cord that the cord is quickly fastened to adjust a length of the window covering.

Abstract: A cord safety device for a window covering includes a first and a second body. The first body includes: a first pivot portion, disposed on a periphery; a first fixing portion, disposed on a periphery at a predetermined angle with respect to the first pivot portion; a first stop portion, disposed on an inner side of the first body and protruded towards the second body; a first recess, disposed on an upper periphery; and a guiding block, disposed on one end of the first stop portion adjacent to the first fixing portion, in which the guiding block has a guiding surface for guiding the cords. The second body includes: a second pivot portion, disposed corresponding to the first pivot portion; and a second fixing portion, disposed corresponding to the first fixing portion, thereby being separably fixed with the first fixing portion.

Abstract: An adjustable hanging apparatus for blind valances is provided. The hanging apparatus includes a hanging device and a mounting device. The hanging device has a hook, which can be slidably hooked over a headrail. In addition, a base of the hanging device has an opening. The opening is disposed with two resilient mounting plates, and each mounting plate has a plurality of troughs. A neck portion is formed therebetween the mounting plates. The mounting device has a joint portion, which can engage with the valance. Also, a jam portion passes through the neck portion and mounted therein. Positioning flanges can be engaged with the troughs of the mounting plates so as to limit the vertical movement of the mounting device, and the mounting device can be inserted through the opening in the vertical direction of any positions to adjust the valance to desired positions.

Abstract: A rotating shaft of louver blades for shutter assembly interconnected between a louver blade and a frame is provided, which includes a bushing and a shaft. A body of the bushing has a through hole and a plurality of slots, such that the body can be deformed flexibly. A front section of the shaft is fitted with the through hole. After the bushing is combined with the frame, the fixing hole is relatively small, which forces the end of the bushing having the slots to be compressed inwards, and after the front section passes through the bushing, the flexibly-deformed portion is expanded outwards, such that the bushing can be engaged with the frame. Moreover, the flexibly-deformed portion of the bushing generates a clipping force to the front section, such that the shaft and bushing are tightly fitted with each other, thereby making the louver blade be easily rotated and positioned.
