An operation part 44 for locking and unlocking is provided on the indoor surface of the locking device 42, and is locked when the operating part 44 is moved downward, and unlocked when the operating part 44 is moved upward.

  In particular, in order to improve crime prevention, as shown in FIGS. 7 to 10, the lower portion of the lower frame 3 b covers the guide portion 30 to reinforce and has an engagement hole 46 a at the upper portion. 1 The reinforcing member 46 is provided, and the lower part of the shutter 5 is located at the lower part of the indoor side of the joint palms (door tips) 14c, 14c that are abutted when the shutters 5 and 5 are fully closed. Floating from the lower frame 3b (specifically, the lower part of the shutter 5 rotates with the slide rail 4 as a fulcrum and moves away from the lower frame 3b) to engage with the engagement hole 46a of the first reinforcing member. A second reinforcing member 47 having a joint portion (engaging protrusion) 47a is provided. The first reinforcing member 46 and the second reinforcing member 47 are formed of a rigid metal plate.

  Among the indoor and outdoor rising pieces 30a and 30b that form the guide portion 30, the indoor rising piece 30b extends from the upper edge thereof toward the indoor side so as to contact the lower frame 6b of the sash frame 6. An extended piece 30d is formed, and the first reinforcing member 46 is substantially applied to the vertical piece 46b applied to the outdoor surface of the outdoor rising piece 30a and the upper surface of the extended piece 30d. It has a substantially L-shaped cross section so as to have a horizontal horizontal piece 46c. The lateral width of the first reinforcing member 46 is about 34 mm. The first reinforcing member 46 is attached to the extended piece 30d by fixing the horizontal piece 46c with a screw (fixing tool) 48. In this case, it is preferable that a back plate 49 for screwing the screw 48 is attached to the lower surface of the extended piece 30d.

  The first reinforcing member 46 can prevent the outdoor rising piece 30a constituting the guide part 30 from being bent or deformed to the outdoor side by a bar or the like. The engagement hole 46a is formed in a portion corresponding to the guide groove 30c in the horizontal piece 46c. On the other hand, like the guide piece 29, the second reinforcing member 47 is formed in an inverted L-shaped cross section, and the hanging piece 47b is suspended in the guide groove 30c. The second reinforcing member 47 is integrally formed with an attachment piece portion 47c for fixing the second reinforcing member 47 with a screw 50 to the lower portion of the indoor surface of the palm palm 14c.

  The second reinforcing member 47 has an extending portion 47d extending in the shutter closing direction integrally formed with the hanging piece 47b, and the engaging portion 47a projects upward at the tip of the extending portion 47d. Has been. When the shutter is fully closed, the extending portions 47d and 47d of the second reinforcing members 47 and 47 provided at the lower part on the indoor side of the palm palms 14c and 14c of the shutters 5 and 5 are the horizontal piece portions 46c of the first reinforcing member 46. It will be in the state where it entered the lower part of. In this shutter closed state (the lock device 42 is locked), an attempt was made to pry open by inserting a bar or the like into the gap between the shutter 5 and the lower frame 3b in the palm bars 14c and 14c of the two shutters 5 and 5. In this case, the engaging portion 47a of the second reinforcing member 47 engages with the engaging hole 46a of the first reinforcing member 46, and it becomes difficult to further pry the shutter 5 out.

  According to the shutter 1 having the above-described configuration, the frame 3 including at least the upper frame 3a and the lower frame 3b disposed outside the window 2 provided in the opening of the building, and the upper frame 3a of the frame 3 The shutters 5 and 5 are slidably opened and closed in a draw-like manner between the lower frame 3b, the slide rails 4 that are provided on the upper frame 3a and slidably support the upper part of the shutter 5 and the lower frame 3b. And a guide portion 30 that slidably guides the guide piece 29 provided in the lower part on the indoor side of the shutter 5, and reinforces and covers the guide portion 30 at the center of the lower frame 3 b. A first reinforcing member 46 having an engagement hole 46a is provided, and the shutter 5 is opened when the shutters 5 and 5 are to be opened at the lower part of the indoor side of the joint palms 14c and 14c that are abutted when the shutters 5 and 5 are fully closed.

  That is, in the closed state of the shutter, when a bar or the like is inserted into the gap between the shutters 5 and 5 and the lower frame 3b of the palm palms 14c and 14c of both shutters 5 and 5, Is covered and reinforced by the first reinforcing member 46, the outdoor rising piece 30a of the guide portion 30 is not easily broken or deformed, and the second lower portion of the shutter 5 is lifted from the lower frame 3b when the peg is opened. The engaging portion 47a of the reinforcing member 47 engages with the engaging hole 46a of the first reinforcing member 46, and it becomes difficult to pry the shutters 5 and 5 further. Therefore, unlike the case where a slide rail or the like is provided on the lower frame as a crime prevention measure, there is no problem that causes an increase in cost, a deterioration in designability or a deterioration in assemblability, and the crime prevention performance can be improved with a simple structure.

  On the other hand, the slide rail 4 has at least a fixed rail 4a provided on the upper frame 3a and left and right movable rails 4c supported slidably directly or indirectly on the fixed rail 4a. 4c is provided on the rear surface of the shutter 5, and is configured to be held in a state of protruding outward from the vertical frames 3c when the shutter 5 is fully opened, so that the rails 4a and 4c are fully closed and fully opened. There is no exposure to the outside of the room, and the design and safety can be improved.

  Further, since the movable rail 4c is slidably supported by the fixed rail 4a via the intermediate rail 4b, the sliding movement of the shutter 5, that is, the opening width can be increased, and a wide lighting area can be secured. it can. Furthermore, since the fixed rail 4a is composed of a single rail that is attached to substantially the entire length of the upper frame 3a, when performing maintenance that involves the attachment / detachment of the fixed rail 4a, the fixed rail 4a differs from the one that is divided into left and right, The fixed rail 4a can be mounted accurately and easily with a good balance between the left and right sides, and the left and right shutters 5 can be supported with a good balance, thereby improving the lockability or locking of the shutters.

  Further, since the vertical frame 3c and the rear portion of the shutter 5 are provided with fully-closed return portions 40a and 40b that engage with each other when the shutter 5 is fully closed and cover the gap, The flutter of the shutter 5 can be suppressed, and the wind pressure resistance can be improved when the shutter 5 is fully closed. Further, since the gap between the vertical frame 3c and the shutter 5 is covered, light leakage can be prevented, and a lock device (sickle lock) 42 can be unlocked or broken by inserting a bar or the like through the gap. There is no, and crime prevention can be improved. Further, since the vertical frame 3c and the rear portion of the shutter 5 are provided with fully-open return portions 41a and 41b that are engaged with each other when the shutter 5 is fully opened to cover the gap, the shutter 5 is fully open. The wind pressure resistance can be improved.
