Description

The present invention relates to a mounting structure of a retrofit window shutter, and more particularly to a mounting structure of a retrofit window shutter to a wall surface of a guide rail base frame.

When installing the window shutter in the window opening, the mounting frame including the guide rail base frame is fixed to the wall using screws, and then the outer wall finish is performed from above, so the screw head is attached to the outer wall. It is buried and not exposed to the outside. However, when retrofitting the window shutter to the outer wall, the base frame 5 'for attaching the window shutter is fixed to the building outer wall W with screws 8', so that the screw head is exposed to the outer wall W and the design is impaired. End up. Therefore, a decorative cover 6 ′ for hiding the screw 8 ′ is mounted on the base frame 5 ′ via the mounting base 7 ′ (see FIG. 10).

Further, in order to prevent water from entering through the gap between the base frame 5 ′ and the outer wall W, coking C ′ is applied between the decorative cover 6 ′ and the outer wall W (see FIG. 10). That is, the decorative cover 6 'has a function as a sealing pocket for filling the caulking material in addition to the function of hiding the screw head. However, in order to perform the caulking process, it is usually time-consuming because it is necessary to perform masking using a masking tape or the like, and the appearance of the coking finish is easily influenced by the skill of the operator (assuming that masking was performed). However, depending on the site, there is a problem that the coking finish is poor and the appearance is impaired.

Patent Document 1 discloses a mounting structure of a retrofit shutter provided with a screw concealed decorative cover. However, the decorative cover forms a sealing pocket filled with a caulking material, and the caulking protrudes from the decorative cover and is exposed. As a result, similar problems may arise.

Is formed. The inner end of the second look side 61 protrudes inward beyond the first look side 62, and an engagement protrusion 67 is formed that protrudes inward from the tip of the first look side 62. That is, the third expected side 65 and the first expected side 62 form left and right engagement sides.

The decorative cover 6 is attached to the attachment base 7 fixed to the attachment side 52. As shown in FIG. 5, the mounting base 7 is a short member formed in a U shape in cross section from the bottom side 70 and the left and right side sides 71 and 72, and the screw 8 is inserted through the center of the bottom side 70. A hole 73 is formed. Engaged portions 710 and 720 are formed on the distal ends of the side edges 71 and 72. A positioning protrusion (which may be a groove) 74 extending in the height direction of the mounting base 7 is formed at the center in the width direction of the bottom side 70. A positioning groove 521 (which may be a protrusion) extending in the height direction is formed on the front surface of the mounting side 52, and the positioning strip 74 on the bottom side 70 of the mounting base 7 is attached to the mounting side 52 as shown in FIG. 6. The mounting base 7 is fixed to the outer wall W using the screw 8 and at the same time the mounting base 7 is mounted. Fix to side 52. The positioning strip 74 is an optional element, and the outer surface of the bottom side 70 of the mounting base 7 may be planar as shown in the left drawing of FIG. An alignment groove 75 extending in the height direction of the mounting base 7 is formed at the center in the width direction of the inner surface of the bottom side 70 of the mounting base 7, and the positioning groove 75 of the bottom side 70 of the mounting base 7 is positioned on the mounting side 52. By matching with the groove 521, the position in the left-right direction (width direction) of the mounting base 7 with respect to the mounting side 52 can be determined. The guide rail base frame 5 is attached to the outer wall W by screwing a plurality of screws 8 at intervals in the height direction. In one embodiment, a screw hole (not shown) is formed in advance on the attachment side 52 of the guide rail base frame 5. The number of screws 8 is equal to or greater than the number of mounting bases 7. In one embodiment, the same number of mounting bases 7 as the number of screws 8 are used. In a state in which the bottom side 70 of the mounting base 7 is in contact with the front surface of the mounting side 52 and is fixed to the mounting side 52 with the screw 8, the tip of the mounting side 52 and the outer end (outer side of the bottom side 70 of the mounting base 7 are outside. The side edges 71) are coincident. The side 72 on the inner side of the mounting base 7 faces the outer surface of the side 50 of the mounting side 52 with a gap, and the third expected side 65 of the decorative cover 6 is received in the gap.

After the base frame 5 is attached to the outer wall W by using the screws 8, the caulking C is applied between the outer wall W and the tip portion outside the attachment side 52 of the base frame 5. More specifically, caulking is performed across the outer end of the bottom side 70 of the mounting base 7, the tip of the mounting side 52, and the outer wall W. The caulking process is performed on the outer wall W without performing a masking process. Next, by pushing the decorative cover 6 against the mounting base 7 from the front, the engagement protrusions 66 and 67 of the left and right engaging sides (the third expected side 65 and the first expected side 62) of the decorative cover 6 are The decorative cover 6 is fitted and fixed to the mounting base 7 by engaging with the engaged portions 720 and 710 of the mounting base 7. In a state where the decorative cover 6 is fixed to the attachment base 7, the first finding side 60 of the decorative cover 6 covers the head of the screw 8, the attachment base 7 and the attachment side 52, and the second finding of the decorative cover 6 is performed. The side 61 and the second expected side 63 cover the caulking C. The second finding edge 61 extends outward from the outer end of the coking C with a margin, and even if the finishing of the coking C is poor, the coking C is not exposed to the outside of the decorative cover 6. Therefore, the masking process can be omitted. As shown in the left diagram of FIG. 7, caps 600 are attached to the upper and lower ends of the decorative cover 6.

The tip of the second prospective side 63 and the bent side 64 of the decorative cover 6 are close to the outer wall W and prevent rainwater from entering the decorative cover 6 as much as possible. Even if rainwater enters from the gap between the tip of the second prospective side 63 and the outer wall W, the caulking C is applied to the gap between the tip of the mounting side 52 and the outer wall W. Because the gravity falls within the internal space formed by the second finding side 61 and the second leading side 63, rainwater does not reach the screw 8. In the case where all the screws 8 are fixed to the mounting side 52 and the outer wall W via the mounting base 7, the side 71 of the mounting base 7 is located outside the head of the screw 8. Intrusion is prevented.

A second embodiment of the present invention is shown in FIG. In the second embodiment, the shape of the decorative cover 6 is similar to that shown in FIG. 4, but an element corresponding to the mounting base 7 is integrally formed on the base end side portion of the base frame 5. More specifically, as shown in FIG. 8, the first expected side 62 extends from the outer end of the first finding side 60 toward the outer wall W, and from the tip of the first seen side 62 toward the outside. The second look side 61 extends, the second look side 63 extends from the outer end of the second find side 61 toward the outer wall W, and the tip of the second look side 63 is close to the outer wall W. In addition, a bent side 64 is formed inward at the tip of the second expected side.

A third look side 65 extends from the inner end of the first look side 60 toward the attachment side 52, and an engaging portion 66 </ b> A is formed on the tip side of the third look side 65. An inner end of the second look side 61 extends inward beyond the first look side 62, and an engaging portion 67 </ b> A that protrudes inward from the tip of the first look side 62 is formed. A rising side 55 is formed at the tip of the attachment side 52, and an engaged portion 710 </ b> A protrudes from the tip of the rising side 55. In one aspect, the rising edge 55 extends in the height direction of the base frame 5. On the outer side surface of the side edge 50, an engaged portion 720A protrudes from the engaged portion 710A.

After the base frame 5 is attached to the outer wall W using the screws 8, the caulking C is applied between the outer wall W and the distal end portion (the base end portion of the rising side 55) outside the attachment side 52 of the base frame 5. . The caulking process is performed on the outer wall W without performing a masking process. Next, by pushing the decorative cover 6 against the base frame 5 from the front, the engaging protrusions 66A and 67A of the decorative cover 6 are engaged with the engaged portions 720A and 710A formed integrally with the base frame 5.
