It is assembled and fixed.

Further, as shown in FIGS. 1 and 4, an eaves body 37 is formed on the frame body 30 of the upper frame 21 at an end opposite to the fixing portion 31. This eaves 37 overhangs from building 1 As shown in FIG. 1, the dimension is set to be larger than the width W of the slat 38 of the blind shutter 19, and the overhang dimension W from the outer wall 6 of the building 1 to the outermost tip of the slat 38 is set. It is set larger than a. Therefore, even if the blind type shutter 19 is opened and the slats 38 protrude outward, rain, snow and dust are prevented from directly falling on the blind type shutter 19.

As shown in FIGS. 4 and 5, guide rails 39 for mounting the blind type shutter 19 are formed on the eaves 37 and the frame body 24 of the lower frame 22 at positions facing each other. The guide rail 39 of the eaves 37 has a guide hole 40 that opens toward the lower surface, while the guide rail 40 of the lower frame 22 has a guide hole 40 that opens upward. Have been.

[0031] As shown in FIG. 2, the blind type shutter 19 is disposed between the two guide rails 39 in a pair on the left and right, and as shown in FIG. 7 and FIG. The slat 38, the elastic tongue 41 for connecting the upper end and the lower end of each slat 38, and the upper tongue 41 are inserted into the guide rail 39 of the eaves 37 through the guide hole 40. A guide roller 42, which is rotatably suspended, and a guide pin 43, which movably engages the lower lage ton 41 in the guide rail 39 of the lower frame 22 through a guide hole 40. It is composed.

[0032] As shown in Figs. 7 and 8, the slat 38 is formed of an elongated plate body, and the lasing tongue 41 is attached to upper and lower ends. Further, as shown in FIG. 11, the slat 38 has locking edges 44 bent in opposite directions on both side ends, and the locking edges 44 are recessed along the vertical direction. A groove 45 is formed. An elongated sealing member 46 (for example, a rubber material) is fixed to the concave groove 45 to improve watertightness when the locking edges 44 of the slats 38 are in close contact with each other.

As shown in FIGS. 8 and 11, a plurality of sets of the tongue 41 are formed by two types of links 47a and 47b having different shapes which are pivotally mounted at the center and rotatable in an X-shape. Is hinged to form an expander-type telescopic unit.

As shown in FIG. 11, one of the links 47a is formed of a plate (a bending angle is set gently), and one of the links 47a is bent in a circular cross section. The link 47b is formed of a plate bent in an L-shaped cross section, and the upper and lower ends of the slat 38 are fixedly fixed to the other link 47b.

As shown in FIGS. 11 and 12, the guide roller 42 has a rod 48 inserted through a hole communicating with one end of the link 47a and 47b, and a rotation at the upper end of the rod 48. A plate-like base 49 that is freely fixed, a rotating shaft 50 that is rotatably inserted in the left and right direction of the base 49 and whose both ends are supported by the guide rail 39, and that is rotatably mounted on the rotating shaft 50. It has a pair of roller portions 51 that are passed through and rotatably supported at both ends, and bearings 52 on the inner peripheral surface of each roller portion 51, and a male screw is formed on the outer peripheral surface at the lower end of the rod 48. Have been. The lower end of the rod 48 is screwed to a nut 54 via a pair of washers 53, thereby being fixed to one end of the other link 47.

As shown in FIG. 8, a frame section 55 having a lock mechanism such as a key lock (not shown) is attached to an end of the blind type shutter 19. When the left and right blind shutters 19 are closed, the two frame portions 55 come into contact with each other and are fixed by the lock mechanism. At this time, as shown in FIG. 9, the steps 55a of the two frame portions 55 are offset from each other on the opposing surface, and the steps 55a of the two frames 55 are woven with each other.

When such a blind shutter 19 is attached to the window opening 2 of the building 1, first, the sash 3 and the window 4 are fitted, and then the fixing portion 31 of the upper frame 21 is opened. 2 is fixed to the outer wall 6 through the through hole 17 with a fixing tool 27 (for example, a screw or a nail) against the outer wall 6 on the upper side.

Specifically, both engaging portions 36 of the frame main body 30 of the upper frame 21 are fitted between the base portions 33 of the holding portions 32 of the fixing portion 31, and the distal ends of the both locking pieces 34 of the fixing portion 31 The frame main body 30 of the upper frame 21 is easily assembled and connected to the fixing portion 31, thereby improving the work efficiency of the mounting operation of the upper frame 21.

[0038] As a result, the frame main body 30 of the upper frame 21 is assembled after the fixing portion 31 is mounted, whereby the upper frame 21 is mounted on the outer wall 6 in two steps. Therefore, even if the overhang of the eaves 37 is larger than the width of the slats 38, the fixing portion 31 of the upper frame 21 and the frame main body 30 can be mounted without the mounting work of the upper frame 21 being hindered by the eaves 37. It can be easily attached, which improves the workability of the attaching work. Further, the fixing portion 31 of the upper frame 21 and the frame main body 30 can be easily lifted alone above the opening 2 of the building 1, so that the mounting work efficiency is also improved in this respect. The two engaging portions 36 of the frame main body 30 assembled and connected to the fixing portion 31 are engaged with the distal ends of the both locking pieces 34 of the fixing portion 31, so that it is difficult to remove and secure the crime prevention. there is no problem.

[0040] Thereafter, the overhang portions 25 of both the vertical frame 23 and the lower frame 22 are applied to the outer wall 6, and are fixed through the through-holes 17 by the fixtures 27 (for example, screws or nails). A frame 20 is attached to the outer wall 6 around the opening 2. Since the elastic body 26 is fixed to the mounting surface of the overhang portion 25 and the fixing portion 31 of the upper frame 21, even if the outer wall 6 of the building 1 has irregularities such as sprays or stones, the elastic body 26 is fixed. This prevents elastic gaps and gaps from forming, thereby preventing rainwater and dust from entering and improving the sealing performance.

[0041] After attaching the shutter guide frame 20 to the outer wall 6 around the opening 2, the pair of right and left blind shutters 20 is fitted. That is, the outer portion of each blind type shutter 20 is fixed to the frame body 24 of the vertical frame 23, and the guide pin 43 is movably engaged with the guide rail 39 of the lower frame 22 through the guide hole 40, and thereafter, The roller part 51 of the guide roller 42 is rotatably mounted in the guide rail 39 of the upper frame 21 through the guide hole 40, and the blind shutter 20 is suspended.

[0042] Since the roller portion 51 has the bearing 52 on the inner peripheral surface that is in sliding contact with the outer peripheral surface of the rotary shaft 50, the roller portion 51 smoothly moves in the left and right direction because the coefficient of friction with the outer peripheral surface of the rotary shaft 50 is small. Therefore, even when a heavy slat 38 (for example, the slat 38 having a large height H in FIG. 1) is used, the blind shutter 20 can be easily opened and closed.

[0043] Then, when the tongues 41 contract, the X-shaped links 47 of the both blind type shutters 20 approach each other inward and outward, and open the opening 2 of the building 1 in parallel so that the slats 38 overlap each other. On the other hand, when the tongs 41 are extended, the X-shaped links are brought closer to each other in the direction of the link 47, and the locking edges 44 of the respective slats 38 are linked to each other so as to be substantially straight, closing the opening of the building.

At this time, since the link 47a is bent in an arc shape in cross section, the strength of the blind type shutter 20 which is strong in the width direction is large (the slat height H and the width in FIG. 1 are large). W Is set to a large value, etc.).

When the opening 2 of the building 1 is closed, the steps 55a of the frame portions 55 of both the blind shutters 19 are engaged with each other. Therefore, when the frame portions 55 are fixed by a predetermined locking mechanism, It is prevented that both frames 55 can be cut open using a thin rod or the like from the outside, and the crime prevention effect is improved in this respect.

Further, when the opening 2 of the building 1 is closed, the sealing member 46 of the slat 38 comes into close contact with the locking edge 44 of the adjacent slat 38, so that the sealing performance of each slat 38 is improved and dew condensation is prevented. It is effective for rainwater measures.

[0047] The present invention is not limited to the above embodiment, but is also applied to, for example, a rain door guide frame 20 of a type in which an eaves body 37 is not formed on a frame body 30 of an upper frame 21. be able to.

[0048] Also in this case, since the frame body 30 of the upper frame 21 is assembled to the fixing portion 31 after the fixing portion 31 is attached, the upper frame 21 is attached to the outer wall in a two-step operation. Can be easily attached without being disturbed by the frame body 30.

[0049] Further, the present invention can also be applied to a rain door guide frame 20 of a type in which the fixing portion 31 and the overhang portion 25 are fixed to the outer wall 6 of the building 1 using an adhesive or the like.

[0050] In this case, the screw and the like are not removed, and the shutter frame 20 is not removed, thereby improving the crime prevention effect. Further, the present invention can be applied to a case where the shutter frame 20 and the sash 3 are integrally formed.

Further, the step 55a of both frame portions 55 is eliminated, and a fitting concave portion is formed on the side end surface of one frame portion 55, and a fitting convex portion is formed on the side end surface of the other frame portion 55. You can also. Also in this case, when the both blind shutters 19 are extended and the opening 2 is closed, the fitting concave portion and the fitting convex portion are fitted, and the opening of the both frame portions 55 is prevented.
