A pair of reeds and a vertical reed connecting the ends of the pair of reeds in the left-right direction, and the upper end of the reed is on the upper side of the pair of reeds The lower end of the vertical rod is disposed in contact with the lower rod disposed on the lower side of the pair of horizontal rods, and both left and right end portions of the upper rod are disposed. And the recessed part dented in the center side of the left-right direction is formed in at least one place of the both ends of the left-right direction of the said lower eyelid, It is characterized by the above-mentioned.

In the joinery constructed in this manner, a so-called horizontal (horizontal winning) frame in which the upper end of the vertical rod is disposed in contact with the upper rod and the lower end of the vertical rod is disposed in contact with the lower rod. have.
In this joinery, a concave portion that is recessed toward the center side in the left-right direction is formed in at least one of both the left-right end portions of the upper heel and the left-right end portions of the lower heel. Therefore, since a member can be attached to the inner peripheral surface of the corner of the frame and the member can be disposed in the recess, interference between the member attached to the corner of the frame and at least one of the upper and lower eyelids can be prevented. Can be suppressed.

  Moreover, the fitting according to the present invention includes a pulley provided on an inner peripheral surface of a corner portion of the frame body, and a linear member hung on the pulley, and the shoji is formed by the linear member, It is preferably configured to be openable and closable.

  In the joinery thus configured, the shoji is configured to be opened and closed by a linear member hung on the pulley. In this joinery, the pulley has a pulley provided at a corner of the frame body and a linear member hung on the pulley can be disposed in the recess, and the pulley and the linear member interfere with at least one of the upper and lower rods. Can be suppressed.

  According to the joinery according to the present invention, it is possible to suppress the interference between the member attached to the corner of the frame and the shoji.

In addition, the wires W hung on the turning pulleys 501 and 502 and the turning pulleys 501 and 502 are disposed in the recesses e1 and e2, respectively, so that the interference between the turning pulleys 501 and 502 and the upper rod 21 and the lower rod 22 is suppressed. You can also.

  Moreover, the part W1 (refer FIG.6 and FIG.8) which faces an up-down direction among the wires W arrange | positioned to the side (the side opposite to the center side of the left-right direction) of recessed part e1, e2 of the upper collar 21 and the lower collar 22. Even if it moves a little, it can suppress that the part W1 of the wire W interferes with the upper collar 21 and the lower collar 22.

  Further, the turning pulley 501 can be arranged in a narrow space slightly above the recess e1, and the turning pulley 502 can be arranged in a narrow space slightly below the recess e2. Therefore, the width of the finding surface (surface along the left-right direction) of the vertical frame 13 or the vertical rod 23 can be reduced, and the design can be improved.

  In addition, the upper eaves 21 and the lower eaves 22 are formed with recesses e1 and e2 at both ends in the left-right direction, and the turning sheaves 501 and 502 are arranged on one side of the upper frame 11 and the lower frame 12 in the left-right direction (viewed from the outdoor side). On the right side). Therefore, on the construction site, the opening / closing mechanism 5 is installed in the left-right direction, that is, the installation position of the turning pulleys 501 and 502 is set at the end of the upper frame 11 and the lower frame 12 on the other side in the left-right direction (left side as viewed from the outdoor side). It is possible to respond on-site to install.

  Moreover, since recessed part e1, e2 is arrange | positioned on the outdoor side rather than the airtight material 109 provided in the vertical shaft 23 by planar view, airtightness is ensured on the indoor side of the turning pulleys 501 and 502 and the wire W109. be able to.

  The various shapes and combinations of the constituent members shown in the above-described embodiments are merely examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

  For example, in the embodiment described above, the step window 100 in which the protruding window 2 is arranged in the vertical direction with the FIX window 3 has been described. However, the present invention is not limited to this, and at least the protruding window 2 is installed. That's fine. For example, a configuration in which only the protruding window is installed, or a continuous window in which the protruding window is arranged side by side with the other windows may be used.

  Further, in the embodiment described above, the recess e1 is formed in the left and right end portions 21a of the upper collar 21, and the recess e2 is formed in the both end portions 22a of the lower collar 22 in the left and right direction. It is not limited to this. It suffices if a recess is provided in at least one of the left and right ends of the upper collar and the left and right edges of the lower collar.

  In the embodiment described above, the opening / closing mechanism 5 is provided at the corners of the four-sided frame 16, but the present invention is not limited to this, and those arranged at the corners of the frame can be appropriately set.
