The operation piece protruding from the upper surface of the upper frame of the sash to the side of the upper frame is rotated 90 degrees around the support shaft, and the operation piece is positioned in the length direction of the head box by the rotation of the operation piece. A pair of overhanging step portions are rotated in the width direction of the head box, and the overhanging step portions are positioned below the claw pieces provided on the upper edge of the rim facing the indoor / outdoor position of the head box. Suspended by a pair of overhanging steps, the tip of the locking piece Blind attachment structure for securing one engagement locks in operating piece on the lower surface of the claw piece of the headbox has been proposed (e.g., see Patent Document 1).

Japanese Utility Model Publication No. 6-51494 (5th, 6th page, FIGS. 4 and 6)

However, in the above-mentioned Patent Document 1, there is no means for restricting the attachment position of the head box in the longitudinal direction, and therefore the entire blind may be attached to one side or the other side from the predetermined attachment position. . Further, Patent Document 1 is disadvantageous because it uses a special-shaped receiving metal fitting in which the operation piece, the overhanging stepped portion, and the locking piece are integrated, which increases the product price of the multiple glass sash.
Further, the blind mounting structure of Patent Document 1 is such that the operation piece of the receiving metal is only locked to one claw piece of the head box and the protruding step of the receiving metal is also locked to the claw piece, respectively. Will be loosened by the vibration when the door is opened and closed indoors or down and the space between the windowpans is raised and lowered, the operation piece and the overhanging step part will come off from the claw piece of the head box, and the blind will fall from the bracket There is no danger of doing so.

  The present invention has been made in the background of such circumstances, and the purpose of the present invention is to easily attach a blind to a constrained space between window panes and to attach to the vibration of the blind after the installation. The object is to provide a blind mounting structure of a built-in blind type multiple glass sash capable of maintaining a good state at a low cost.

The head box is positioned at a predetermined mounting position in the length direction by fitting the accommodation recess on one rim side and the locking projection on the metal fitting side.
The set screw, which is the key to fixing the head box to the mounting bracket, presses the tip of the head box against the inside of the upper part of one rim of the head box, so the reaction force received from one rim acts as a locking force on the set screw. Then, the set screw screwed into the female screw hole is loosened and the screwed state is securely maintained. Further, the tip of the set screw presses the upper inner side of one rim without loosening, so that the fitting state between the receiving recess provided on the upper outer side of the one rim and the locking projection on the receiving metal fitting side is maintained satisfactorily. .

In addition, by cutting out a part of the other rim of the head box and opening a female screw hole in the cut piece positioned parallel to the one rim side, the female screw hole is positioned on the space side. By doing so, when the set screw is screwed into the female screw hole, the protruding amount of the head of the set screw located outside the other rim is reduced. Thereby, the width | variety of the space part between windowpanes is suppressed to the required minimum, and the freedom degree of the windowpane arrange | positioned at the other rim | limb side improves.
Furthermore, it is necessary to screw the set screw into the female screw hole by forming this female screw hole on the inner peripheral surface of the boss part bulged from the notch piece of the other rim to the one rim side. Long length can be secured.

According to the blind suspension structure of a built-in blind type multiple glass sash of the present invention, a blind can be easily attached to a constrained space between indoor and outdoor window glasses in a short time. In addition, the head box can be easily positioned at a predetermined mounting position in the length direction by fitting the accommodation recess on one rim side and the locking projection on the receiving metal side. Further, it is not necessary to use special parts as in Patent Document 1, and since the configuration is simple, it can be provided at low cost.
Furthermore, after installing the blinds, the set screw that is required for installation presses against one rim of the headbox and receives a reaction force. This reaction force prevents the set screw from loosening, and the slats open and close in the indoor and outdoor directions. Even if it receives vibrations when moving up and down the space between the windowpanes, it is possible to keep the blinds attached well.
