Abstract: An obstacle detection stopping device of a solar radiation shielding apparatus capable of suppressing the wear of a lifting cord due to the contact of a slat with the lifting cord. The obstacle detection stopping device (10) comprises a support member (11), a rotary drum (13), a cam clutch (12), and a winding pulley (9). A drive shaft (8) is passed through the inside of the device. A rotating force in the unwinding direction is transmitted to the drive shaft (8) by a tension applied to the winding pulley (9). The rotary drum (13) is integrally fitted to the drive shaft (8), and the cam clutch (12) is fitted to the outer edge thereof so as to be rotated relative to each other. Based on the relative rotation of the cam clutch (12) to the rotary drum (13), the cam clutch (12) is moved along its axial direction to change the state of its engagement with a braking projected part (11g). The cam clutch (12) is installed so as to be non-rotated relative to the winding pulley (9).

Abstract: Disclosed is a fixture structure for fixing a rail member to an attaching surface, such as a wall. The frame to be attached to the attaching surface has a first support for supporting a first attaching piece of a rail member. The slide block, attached slidable to the frame, has a second support for supporting a second attaching piece of the rail member. The slide block slides between a supporting position where the second support can support the second attaching piece and a releasing position where the second support releases the second attaching piece. A spring is provided to urge the slide block toward the support position. The slide block has an actuating piece whose position can be changed to a direction different from a direction of the slide block sliding. When the slide block is shifted to the release position, the actuating piece engages with a part of the frame to hold the slide block at that position.

Abstract: An improved winding apparatus for a roller blind is disclosed. The winding apparatus includes a clutch mechanism provided between the winding roller and the cord pulley for transmitting rotation of the pulley to rotation of the winding roller. The clutch mechanism is arranged to prevent the urging mechanism from rotating the winding roller when the cord is not handled. It also allows the pulley to rotate a predetermined angle in a screen lifting direction when the cord is operated to lift the screen. At this point, the urging mechanism is permitted to rotate the winding roller in the screen lifting direction. Additionally, when the pulley is rotated by the cord in a screen lowering direction the pulley is first allowed to rotate freely for a predetermined angle. Thereafter, the screen lowering motion of the cord is transmitted through said pulley to said winding roller to lower the screen.

Abstract: A pair of lifting cords are connected to a bottom rail at their lower ends and are connected to ends of a head box at their upper ends so as to lift and lower the slats of a blind. A pair of winding drums are provided in the head box which rotate together and move in the longitudinal direction of the head box. The lifting cords are introduced into the head box at the ends thereof. The lifting cords are guided so as to extend in the moving direction of the winding drums and are fitted to the wind starting ends of the winding drums. The moving ranges of the winding drums are set inside relative to the lifting cord introducing portions. As the winding drums rotate, the lifting cords are wound around the outer periphery of the winding drums. As the lifting cords are wound, the slats are lifted and lowered.

Abstract: Disclosed is an apparatus for cutting blind slats, including a conveying device for sequentially conveying a slat material and a cutting device turned on and off in synchronism with the conveyance of the slat material so as to form slats of a desired length, wherein the improvement is characterized by comprising: an input device having means for entering the length of a slat; a control device for converting the output signal of the input device to pulse signals corresponding to the slat length entered and outputting them; and a motor rotated on the basis of the pulse signals output from the control device so as to convey the slat material by predetermined lengths.

Abstract: An apparatus for fabricating a blind. This blind fabricating apparatus is constituted by: input devices for inputting a height of the blind and a length of a slat; an arithmetic and logic means for computing the number of steps of the slats which corresponds to the inputted height of the blind and positions at which insertion holes for an ascending-descending cord are formed in the slats on the basis of output signals of the input devices; and a slat inserting device for cutting the slat material to a predetermined length, forming the insertion holes for the ascending-descending cord in the slats, and inserting the slats through a plurality of ladder cords.

Abstract: Relates to a blind, comprising a head box, an operating rod dropped from one side of the head box, an angle control shaft in the head box which is driven to rotate by the operating rod, a multiplicity of slats controlled for angle by rotations of the angle control shaft, a slat angle controller having a gear mechanism provided between the operating rod and the angle control shaft, the gear mechanism comprising a first gear shaft extending diagonally in section of the head box, a second gear shaft extending longitudinally of the head box, and gears coupling the first and second gear shafts.

Abstract: A shutter is provided which is moved up and down by the use of the urging force of a take-up spring for turning a take-up shaft that winds up a number of slats and the weight of the slats. These slats are mutually coupled vertically expandably and a number of slits are formed in expandable portions of individual slats. The shutter includes a slit open/close means for expanding and contracting the slats to open/close the slits.

Abstract: A venetian blind includes a multiplicity of horizontal slats arranged in vertically spaced relation below a head box. The head box is of a rectangular tubular construction composed of elongate support and cover bars. The support bar includes at least a front side wall and a lower wall, and the cover bar is attached to the support bar in covering relation to an open side of the support bar. The head box accommodates therein a slat tilt adjustment device for adjusting the angle of tilt of the slats.

Abstract: A window having a blind disposed between interior and exterior panes of glass. A glazed interior door is movably disposed on the lower frame of a glazed exterior door, and the blind is disposed between these doors to form a double-glazed door. A plurality of sash rollers are movably mounted to the lower frame of the interior door and capable of moving along the rails mounted to the lower frame of the exterior door. Screws are detachably screwed into the interior and exterior doors to prevent these doors from moving relative to each other. The double-glazed door is arranged on the rails in the sash via a plurality of sash rollers which are rotatably mounted to the lower frame of the exterior door.
