The guiding part 230 formed as described above, as shown in Fig. 1, Fig. 3 ~ Fig. 5, is top with pin plate portion 232 and guide channel 234 is arranged on the depth face of vertical members of frame 21 along the state of above-below direction via pin plate portion 232 and sliding panel portion 233.

The place of installing guiding part 230 as shown in Figure 5, be the engagement pin 131 of the restricted arm 130 hung down from parent plate 132 when bar 10 is closed than the side walls 231b being positioned at the below of guiding box portion 231 more on the lower and than the front end height and position by the top of slide unit 240 being configured in release position.In addition, the position of setting left and right, to make the vertical upper opening of guide channel 234 at engagement pin 131 of guiding part 230.

In this condition, make the sliding manipulation part 248 that is located on slide unit 240 outstanding to the inner circumferential side of opening frame 20 along the abutting fin part 21a of vertical members of frame 21, crossing the position abutting fin part 21a, operation knob 248c is configured in faced chamber.Thus, under the state closing bar 10, also can carry out the operation of operation knob 248c in side indoor, if locking component 247 is configured in the state of unlocked position, then slide unit 240 can be made to slide up and down relative to vertical members of frame 21.In addition, in pin plate portion 232, at the upper corner of indoor, banking pin 250 is installed.This banking pin 250 is the parts preventing restricted arm 130 from rotating towards indoor when closing bar 10.

In addition, be located at limiting part 40 on guiding part 230 due to from datum 40Ad, 40Bd to limiting unit 40Ac, the distance of leading section 40Ag, 40Bg of 40Bc is set as slightly larger than the side walls 231b in guiding box portion 231, so be crimped on the state on the depth face of vertical members of frame 21 for leading section 40Ag, 40Bg of limiting unit 40Ac, 40Bc.

Now, under the state that bar 10 is closed, if operation knob 248c is operated downward from the state shown in Fig. 5, slide unit 240 is configured to release position, then between the guide channel 234 and the accepting groove 243 of slide unit 240 of guiding part 230, produce gap, the end of the end and accepting groove 243 that become guide channel 234 is respectively by the state opened.Thus, if opened by bar 10 from this state, then as shown in Figure 3, along with the movement of bar 10, the engagement pin 131 of restricted arm 130 moves to outside through the guiding box portion 231 of guiding part 230 and the gap of slide unit 240.In this condition, due to not to bar 10 any restriction in addition, so bar 10 can be opened to fully open position.

On the other hand, under the state shown in fig. 5, namely, under the state being configured in locked position of coupler at slide unit 240, the engagement pin 131 of restricted arm 130 is positioned at the inside of the accepting groove 243 be located on slide unit 240, becomes the confined state of movement to depth direction.Thus, when being opened by bar 10 from this state, the mount pin 134 of restricted arm 130 moves to outside together with bar 10, but engagement pin 131 can not move on depth direction.As a result, as shown in Figure 4, if bar 10 moves to the direction of opening, then restricted arm 130 rotates centered by mount pin 134, and engagement pin 131 is moved upward gradually along accepting groove 243 and guide channel 234.If engagement pin 131 reaches the constrained side end 234a of guide channel 234, then the rotation of restricted arm 130 is prevented from, so the movement of the opening direction of bar 10 is also stopped, bar 10 is half-open state relative to opening frame 20.

Here, on guiding part 230, as described above, limiting part 40 is configured with at the constrained side end 234a of guide channel 234.Thus, the engagement pin 131 of restricted arm 130 is as shown in Fig. 8 ~ Figure 10, in the process arrived to the constrained side end 234a of guide channel 234, the limiting unit 40Ac of limiting part 40,40Bc are suitably out of shape while pass, become the state be fastened on via end face on step-like portion 40Ab.Thus, in order to make the engagement pin 131 of restricted arm 130 move towards the open sides end 234b of guide channel 234, need to make the limiting unit 40Ac of limiting part 40,40Bc be out of shape the power of passing.Thus, the bar 10 becoming half-open position is subject to larger restraint forces by limiting unit 40Ac, the 40Bc of limiting part 40, even under the situation of such as wind, also can maintain the state opened and continue to carry out indoor ventilation.

Particularly, the limiting part 40 of present embodiment is by forming the second leaf spring 40B relative to the first leaf spring 40A overlap.Therefore, the open sides end 234b of guide channel 234 is arrived through limiting unit 40Ac, 40Bc in order to make engagement pin 131, need the limiting unit 40Bc of the second leaf spring 40B is out of shape together with the limiting unit 40Ac of the first leaf spring 40A, can the restraint forces of engagement pin 131 be set larger.Thus, when the door and window possessing above-mentioned stop device 30 is arranged on the high-storey of the larger mansion of wind load, the unexpected situation of closing of bar 10 also can be prevented.In addition, due to by metal forming first leaf spring 40A and the second leaf spring 40B, so also do not cause the worry of the problem of durability.

Further, because above-mentioned limiting part 40 limits the parts that abut with engagement pin 131 via the first leaf spring 40A, so can be unrestricted and change its width about the second leaf spring 40B.Thus, when the restraint forces of engagement pin 131 is set less, can by by the dimension enlargement of notch part 41B, make the width of the step-like portion 40Bb and limiting unit 40Bc of the second leaf spring 40B reduce further come corresponding.On the contrary, when the restraint forces of engagement pin 131 is set larger, as long as it is just passable to make the size of notch part 41B reduce.In these cases, owing to not needing the thickness of slab of the first leaf spring 40A or the wide change of plate, in addition do not need the thickness of slab of the second leaf spring 40B to change, so do not need to prepare the different steel plate of multiple thickness of slab, do not cause the worry of the increase of complexity or the manufacturing cost managed yet.

In addition, in the above-described embodiment exemplified with opening window, but might not be limited to and open window, as long as single sliding window or two sliding windows etc., bar 10 relative to the door and window of opening frame 20 opening and closing, also can be applied in other door and windows.

In addition, in the above-described embodiment, the frame parts of bar 10 arranges restricted arm 130, the members of frame of opening frame 20 arranges guiding part 230, but also can arrange restricted arm 130 and guiding part 230 with contrary form.

And then, in the above-described embodiment, at the middle body of the second leaf spring 40B, notch part 41B is set, but the utility model might not be defined in this, make the width dimensions in the direction orthogonal with the bearing of trend of guide channel 234 little than the first leaf spring 40A and the narrow part that forms is just passable as long as arrange on the second leaf spring 40B.That is, also narrow part can be formed by forming notch part 41B in the office, both sides of the second leaf spring 40B.

And then arrange engagement pin 131 in restricted arm 130, but engaging part might not need to be pin-shaped, as long as can engage with limiting part when bar is opened to the restriction site of regulation relative to opening frame, can certainly be other shapes.
