Claims (6)

[Claims] An upper, lower, left and right spacer is connected in a rectangular frame shape, and a double-layered glass is formed in which both sides of the spacer are sandwiched by glass plates and the inside is sealed. Hanging a blind whose angle can be adjusted through, and disposing a pulley that drives the hanging string on the upper spacer,
An operation unit is provided on the outer surface of the multilayer glass so as to be movable up and down, and an operated portion that is attracted and operated by magnetic force to the operation unit is provided so as to be movable up and down along a spacer on a side portion in the multilayer glass. The pulley is rotatably operated from the operated portion via the curved guide portion at the upper corner by a flexible transmission member for transmitting linear motion along the side and upper spacers. Double-glazed glass with built-in blinds. 2. A double-layered glass in which the upper, lower, left and right spacers are connected in a rectangular frame shape, and both sides of the spacers are sandwiched between glass plates to form a double-layered glass whose inside is sealed. A blind whose angle can be adjusted is suspended through, a pulley for driving the suspension string is disposed in the upper spacer, and a clutch spring connected to the suspension string is provided at both ends of each pulley by winding the clutch spring. The double glazing with built-in blinds is characterized in that the clutch spring is configured so that when one of its both ends abuts against a stopper so that the clutch spring does not rotate beyond a certain range, the constraint on the pulley is released. 3. A double-layer glass in which the upper, lower, left and right spacers are connected in a rectangular frame shape, and both sides of the spacer are sandwiched between glass plates to form a double-layered glass whose inside is sealed. A blind whose angle can be adjusted is suspended through the above, a pulley for driving the suspension string is disposed on the upper spacer so as to be rotatable in parallel with the glass surface, and the rack is linearly movable along the upper spacer. A driving member having
A double-glazed glass with built-in blinds, wherein a pinion that meshes with the rack is provided on the pulley to rotate the pulley. 4. Upper and lower, left and right spacers are connected in a rectangular frame shape, and a double-layer glass is formed in which both sides of the spacer are sandwiched between glass plates and the inside of the double-layer glass is sealed. Hanging a blind whose angle can be adjusted through, a pulley for driving the hanging string is rotatably arranged on the upper spacer, and an operation unit is provided on the outer surface of the double glazing so as to be able to move up and down, An operated part which is operated by being attracted to the operating part by magnetic force is provided so as to be vertically movable along side spacers in the multilayer glass, and is a flexible member which transmits a linear motion along the side and upper spacers. A window sash comprising a double-glazing unit with a built-in blind configured to rotate the pulley from the operated portion via a curved guide portion at an upper corner by a transmission member having a property. 5. A double-layered glass in which the upper, lower, left and right spacers are connected in a rectangular frame shape, and both sides of the spacers are sandwiched between glass plates to form a double-layered glass whose inside is sealed. A blind whose angle can be adjusted is suspended through, a pulley for driving the suspension string is disposed in the upper spacer, and a clutch spring connected to the suspension string is provided at both ends of each pulley by winding the clutch spring. The clutch spring is equipped with a double glazing with built-in blinds configured to release the restraint on the pulley when one of its ends comes into contact with the stopper so that the clutch spring does not rotate beyond a certain range. Window sash. 6. A double-layer glass in which the upper, lower, left and right spacers are connected in a rectangular frame shape, and both sides of the spacer are sandwiched between glass plates to form a double-layer glass whose inside is sealed. A blind whose angle can be adjusted is suspended through the above, a pulley for driving the suspension string is disposed on the upper spacer so as to be rotatable in parallel with the glass surface, and the rack is linearly movable along the upper spacer. A driving member having
A window sash, wherein a double-glazed glass with a built-in blind is mounted on the pulley and provided with a pinion that meshes with the rack to rotate the pulley.
