Description

The present invention relates to a shutter unit that is attached to a building that has a shutter frame.

As an example of a shutter unit that can be installed in a building that has a storm shutter frame, there is a shutter device that can be installed on top of the storm shutter unit, leaving the storm shutter unit as is, as a form of renovation for the storm shutter unit that includes the storm shutter frame, storm shutters, and door pocket (see, for example, Patent Document 1). This shutter device has a support frame and a light-blocking member (shielding member). The light-blocking member is made of an elastic body such as rubber or sponge, and is fixed to the side of the support frame that faces the door pocket, and is sandwiched between the end plate of the door pocket.

JP 2018-119382 A

In the conventional shutter device described above, the light-shielding member, which is made of an elastic material and is a separate member from the vertical frame of the support frame, is fixed to the side of the vertical frame facing the door pocket and sandwiched between the end plate of the door pocket. For this reason, the light-shielding member must be fixed in a position where it is sandwiched between the end plate of the support frame, and must be formed to a size that matches the distance between the door pocket and the end plate. Since the shutter frame differs for each site where the shutter device is to be installed, a light-shielding member of a size that matches the site of construction must be prepared and installed in a position that matches the shutter frame at the site of construction, which creates the problem of cumbersome work.

The present invention was made in consideration of these problems, and its purpose is to provide a shutter unit that can prevent light and other elements from entering the inside of a building from between the shutter frame and the door pocket.

The main invention for achieving this object is a shutter unit that is attached to a building in which a storm shutter frame is provided, the shutter unit having a shutter frame that is attached to the building, the shutter frame having an upper shutter frame that is arranged above the opening formed by the storm shutter frame, a lower shutter frame that is arranged below the opening, and a pair of vertical shutter frames that vertically connect the end of the upper shutter frame and the end of the lower shutter frame, the vertical shutter frame on the door pocket side of the storm shutter frame having an extension portion that extends toward the building further than the outdoor end of the door pocket.
Other features of the present invention will become apparent from the following detailed description of the present invention and the accompanying drawings.

The present invention makes it possible to provide a shutter unit that can prevent light and other elements from entering the inside of a building through the gap between the shutter frame and the door pocket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A shutter unit according to an embodiment of the present invention will now be described with reference to the drawings.
As shown in FIG. 1, the shutter unit 1 of this embodiment is a shutter unit 1 that is newly attached to, for example, a building 10 on which a storm shutter unit 2 is already installed.

In the following explanation, when the shutter unit 1 attached to the building 10 is viewed from the outside, the up and down directions are referred to as the up and down directions, the left and right directions are referred to as the left and right directions, and the indoor and outdoor directions are referred to as the prospective directions. Even when each part of the shutter unit 1 or each component that constitutes the shutter unit 1 is in a separate state, the directions are specified and explained in terms of the up and down directions, left and right directions, and prospective directions when the shutter unit 1 is attached.

The storm shutter unit 2 provided in the building 10 to which the shutter unit 1 of this embodiment is attached is provided on the outdoor side of a sash frame 12 in which a sliding door (not shown) is provided, and is attached to the sash frame 12 and the building 10, as shown in Figures 1 to 4.

The storm shutter unit 2 has a storm shutter 20 and a storm shutter frame 22 that has a door pocket 21 positioned to the left of the sash frame 12 and forms an opening 2a.

The shutter frame 22 has a door pocket 21 attached to the building 10, an upper shutter frame 22a and a lower shutter frame 22b that form rails along which the shutters 20 are guided, and a vertical shutter frame 22c that connects the ends of the upper shutter frame 22a and the lower shutter frame 22b opposite the door pocket 21. The door pocket 21 can accommodate multiple shutters 20 stacked in the forward direction, and protrudes further outdoors than the shutter frame 22 attached to the building 10.

The door pocket 21 has an upper door pocket frame 21a and a lower door pocket frame 21b connected to the upper rain shutter frame 22a and the lower rain shutter frame 22b, respectively, a vertical door pocket frame 21c connecting the left ends of the upper door pocket frame 21a and the lower door pocket frame 21b, and an outdoor vertical frame 21d connecting the parts of the right ends of the upper door pocket frame 21a and the lower door pocket frame 21b that protrude beyond the rain shutter frame 22. Here, the outdoor vertical frame 21d is provided on the side of the door pocket 21 and forms an opening for inserting and removing the rain shutter 20, and corresponds to the entrance/exit forming part that faces the shielding piece described below.

The shutter unit 1 has a shutter device 3 capable of closing the opening 2a formed by the storm shutter frame 22, and closing members 32a and 32b that close the gap S that occurs between the door pocket 21 provided in the storm shutter frame 22 and the shutter frame 31 provided in the shutter device 3.

The shutter device 3 has a shutter frame 31, a shutter box 33, and a shutter curtain 35 that is wound around a rotating shaft 34 and stored within the shutter box 33. The shutter curtain 35 is configured to be unwound from the shutter box 33 when the rotating shaft 34 is rotated by a motor (not shown) or the like, or to be wound up within the shutter box 33.

As shown in Figure 5, the shutter frame 31 has a shutter main frame 36, a shutter base frame 37, and a screw cover 43 for hiding the screws that secure the shutter frame 31. The shutter main frame 36 supports the shutter box 33 and has a guide rail 36a (Figure 3) that guides the shutter curtain 35, and the shutter base frame 37 is interposed between the shutter main frame 36 and the building 10. The guide rail 36a is omitted in Figure 5. The screw cover 43 does not necessarily have to be provided.

The shutter body frame 36 is equipped with guide rails 36a and has an upper body frame 36d and a middle body frame 36e arranged above the opening 2a formed by the storm shutter frame 22, a lower body frame 36c arranged below the opening 2a, and a pair of vertical body frames 36b arranged on the left and right that connect the ends of the upper body frame 36d and the middle body frame 36e to the ends of the lower body frame 36c vertically. The upper body frame 36d and the middle body frame 36e are arranged with a gap between them in the vertical direction between the pair of vertical body frames 36b, forming a space to store the shutter box 33. The shutter box 33 is supported by the left and right vertical body frames 36b via brackets (not shown).

The shutter base frame 37 is interposed between the shutter main frame 36 and the building 10 in order to position the shutter main frame 36 on the outdoor side relative to the upper rain shutter frame 22a and the lower rain shutter frame 22b of the rain shutter unit 2 attached to the building 10. The shutter base frame 37 has a base base frame 37a interposed between the main body lower frame 36c and the building 10, a pair of base frame 37b, 37c interposed between the main body upper frame 36d and the main body middle frame 36e and the building 10, a base vertical frame 38 connecting the ends of the base base frame 37a and the pair of base frame 37b, 37c on the opposite side to the door pocket 21, and a base vertical outdoor frame 39 connecting the parts located on the outdoor side relative to the upper rain shutter frame 22a and the lower rain shutter frame 22b at the ends of the base base frame 37a and the pair of base frame 37b, 37c on the door pocket 21 side. Here, the main body upper frame 36d, the main body middle frame 36e, and the pair of base upper frames 37b, 37c correspond to the shutter upper frame 31a, the main body lower frame 36c and the base lower frame 37a correspond to the shutter lower frame 31b, and the left and right main body vertical frames 36b, the base vertical frame 38, and the base vertical outdoor frame 39 correspond to the shutter vertical frame 31c.

Two end plates 40, 41 are attached to the shutter base frame 37 at the door pocket 21 side ends of the base base frame 37a and the pair of base frame surfaces 37b, 37c, which are closer to the building 10 than the base vertical outdoor frame 39. The base base frame 37a, the pair of base frame surfaces 37b, 37c, the base vertical frame 38, and the base vertical outdoor frame 39 are all extruded aluminum members. The base base frame 37a and the pair of base frame surfaces 37b, 37c are provided with screw threading portions 37d along the longitudinal direction into which screws 5 are screwed to fix the base vertical frame 38, the base vertical outdoor frame 39, and the end plates 40, 41.

The base vertical frame 38 and the base vertical outdoor frame 39 are fixed by screws 5 screwed into the screw threaded portions 37d of the base base frame 37a and the pair of base base frames 37b, 37c, and the two end plates 40, 41 are fixed by screws 5 screwed into the screw threaded portion 37d of the lower base base frame 37c, as shown in FIG. 6, on one side, and screws 5 screwed into the screw threaded portion 37d of the base base frame 37a on the other side. Therefore, the door pocket 21 side of the shutter base frame 37 is connected on the outdoor side by the base vertical outdoor frame 39, and the end plates 40, 41 are attached to the upper end side and the lower end side, respectively, on the building 10 side of the base vertical outdoor frame 39.

As shown in FIG. 3, the base vertical frame 38 has a generally rectangular vertical frame main body 38b that forms a hollow portion 38a penetrating in the vertical direction, and a vertical frame fixing portion 38c that extends to the right from the edge of the vertical frame main body 38b on the building 10 side and is fixed to the building frame of the building 10. When the building 10 side part of the vertical frame main body 38b of the base vertical frame 38 is abutted against the building 10 and the vertical frame fixing portion 38c is fixed to the building frame, the outdoor side surface of the vertical frame main body 38b is located further outdoors than the upper rain shutter frame 22a, the lower rain shutter frame 22b, and the vertical rain shutter frame 22c. The right side vertical main body frame 36b is fixed to the outdoor side surface of the vertical frame main body.

As shown in FIG. 7, the base vertical outdoor frame 39 located on the door pocket 21 side has a vertical outdoor frame main body 39b that is approximately rectangular and has a hollow portion 39a penetrating in the vertical direction, and a shielding piece 39c that is a plate-shaped extension that extends from the edge of the vertical outdoor frame main body 39b on the door pocket 21 side toward the building 10 in the projection direction and has a projection surface. The shielding piece 39c has multiple break-off parts 39d that are weak parts with a thin plate thickness and are spaced apart from each other in the projection direction and extend in a line along the vertical direction. The shielding piece 39c can be folded along the break-off parts 39d to remove the tip side part 39e of the shielding piece 39c, which is called a break-off. By breaking it off, the extension amount of the shielding piece 39c from the vertical outdoor frame main body 39b can be adjusted. The shielding piece 39c may be cut along the break-off parts 39d with a blade such as a cutter.

The shutter base frame 37 is attached to the building 10 with the lower base top frame 37c positioned above the upper shutter frame 22a of the shutter unit 2 installed on the building 10, the lower bottom frame 37a positioned below the lower shutter frame 22b, and the base vertical frame 38 positioned to the right of the vertical shutter frame 22c. At this time, as shown in Figure 7, the shielding piece 39c of the base vertical outdoor frame 39 and the outdoor vertical frame 21d of the shutter frame 22 face each other with a gap in the left-right direction.

The base vertical outdoor frame 39 is provided on the outdoor side with a gap in the projection direction from the upper and lower rain shutter frames 22a and 22b, and the tip portion 39e of the shielding piece 39c is broken off by a break-off portion 39d provided at an appropriate position so that it does not protrude further toward the building 10 than the opposing outdoor vertical frame 21d. A cover material 42 that covers the edge of the tip is attached over the entire length to the tip of the shielding piece 39c after the tip portion 39e is broken off. The cover material 42 may be any material that covers the edge of the tip of the shielding piece 39c from the indoor side, such as an edge material as shown in the figure that has an L-shaped cross section and covers the edge of the tip, or an edge material or tape that has a U-shaped cross section and into which the tip is inserted.

When the shutter base frame 37 is installed on the building 10, the door pocket 21 side of the shutter frame 31 has gaps between the top surface of the door pocket 21 and the upper end plate 40, and between the bottom surface of the door pocket 21 and the lower end plate 41, between the base vertical outdoor frame 39 and the building 10, when viewed from the door pocket 21 side. Also, as shown in FIG. 8, between the shutter frame 31 and the door pocket 21, a gap S is generated along the projection direction between the base vertical outdoor frame 39 and the outdoor side vertical frame 21d when viewed from above. The gap S between the base vertical outdoor frame 39 and the outdoor side vertical frame 21d is also the same when viewed from below.

For this reason, blocking members 32a, 32b are provided to block this gap S. As shown in FIG. 6, the blocking members 32a, 32b have opposing plate portions 320a, 320b that face the outdoor vertical frame 21d of the door pocket 21, an elastic member 321 such as urethane foam that is provided on the door pocket 21 side of the opposing plate portions 320a, 320b, and fixing plate portions 322a, 322b that are connected to the opposing plate portions 320a, 320b and are fixed together with the end plates 40, 41 of the shutter frame 31 by screws 5 that are screwed into the screw-threaded portions 37d of the lower base frame 37a and the lower base frame 37c.

The fixing plate parts 322a, 322b have elongated holes 323a, 323b that are long in the vertical direction and through which the screws 5 that are screwed into the screw threading parts 37d are inserted. Therefore, the closing members 32a, 32b can adjust the distance between the opposing plate parts 320a, 320b and the upper surface of the door pocket 21. Therefore, when the closing members 32a, 32b are fixed to the lower frame 37a and the lower frame 37c together with the end plates 40, 41, the elastic members 321 provided on the opposing plate parts 320a, 320b are pressed against the door pocket 21 to compress the elastic members 321, and the closing members 32a, 32b are fixed in this state, thereby closing the gap S that occurs between the shutter frame 31 and the door pocket 21.

The shutter unit 1 is attached by first joining the base vertical frame 38 and the base vertical outdoor frame 39 to the base underground frame 37a and the pair of base upper frames 37b, 37c, and then fixing the two end plates 40, 41 to the base underground frame 37a and the pair of base upper frames 37b, 37c to form the shutter base frame 37. At this time, the shielding piece 39c of the base vertical outdoor frame 39 is aligned with the outdoor vertical frame 21d of the door pocket 21 installed at the construction site, and the portion 39e on the tip side of the break-off portion 39d installed at an appropriate position of the shielding piece 39c is broken off so that the outdoor vertical frame 21d is covered by the shielding piece 39c when viewed from the indoor side, and so that the shielding piece 39c does not come into contact with the upper rain shutter frame 22a and the lower rain shutter frame 22b.

At this time, the blocking members 32a, 32b are provisionally fixed to the lower base frame 37a or the lower base frame 37c together with the two end plates 40, 41. The upper blocking member 32a is provisionally fixed higher so that the screws 5 are located below the long holes 323a, and the lower blocking member 32b is provisionally fixed lower so that the screws 5 are located above the long holes 323b.

Next, the shutter base frame 37 is attached to the building 10. At this time, the base vertical outdoor frame 39 and the outdoor side vertical frame 21d of the door pocket 21 are arranged facing each other with a gap in the left-right direction. As a result, the shielding piece 39c protrudes toward the building 10 side from between the base vertical outdoor frame 39 and the outdoor side vertical frame 21d into the space that connects to the outdoor side of the opening 2a, and when viewed from the indoor side, the outdoor side vertical frame 21d of the door pocket 21 is covered by the shielding piece 39c of the base vertical outdoor frame 39.

Next, the screws 5 that temporarily secure the blocking members 32a and 32b to the shutter base frame 37 are loosened, and the upper blocking member 32a is moved downward to press the elastic member 321 against the door pocket 21 and fix it in a compressed state, and the lower blocking member 32a is moved upward to press the elastic member 321 against the door pocket 21 and fix it in a compressed state.

Next, the shutter box 33 is attached to the shutter base frame 37 along with the shutter main frame 36, completing the installation of the shutter unit 1.

According to the shutter unit 1 of this embodiment, when the shutter unit 1 is attached to the building 10 equipped with the storm shutter 20, the shielding piece 39c of the base vertical outdoor frame 39 on the door pocket 21 side of the storm shutter frame 22 protrudes toward the building 10 side in the space between the door pocket 21 and the base vertical outdoor frame 39 that connects to the outdoor side of the opening 2a. Therefore, it is possible to suppress the intrusion of light, wind, rain, etc. from between the door pocket 21 and the base vertical outdoor frame 39 to the building 10 side. In other words, by simply attaching the shutter unit 1 to the building 10 equipped with the storm shutter 20, it is possible to easily suppress the intrusion of light, wind, rain, etc. from between the shutter frame 31 and the door pocket 21 to the indoor side. In addition, since the base vertical outdoor frame 39 has the shielding piece 39c, it is also possible to block the line of sight directed toward the indoor side.

In addition, the shielding piece 39c has multiple break-off sections 39d that are spaced apart from each other in the projection direction and run vertically, so the length of the shielding piece 39c in the projection direction can be adjusted by bending and cutting the section 39e on the tip side of the break-off section 39d. This makes it possible to change the length of the shielding piece 39c as needed to suit the construction site. This makes it possible to provide a shutter unit 1 with excellent versatility.

In addition, the shielding piece 39c is provided on the side of the door pocket 21 and faces the outdoor vertical frame 21d of the door pocket 21, which forms the insertion and removal opening 21e for the storm shutter 20, so it is possible to cover the outdoor vertical frame 21d of the existing storm shutter frame 22 with the shielding piece 39c. Therefore, the outdoor vertical frame 21d of the remaining storm shutter unit 2 is covered by the shielding piece 39c, which can improve the design. Note that the shielding piece 39c may be in contact with the outdoor vertical frame 21d of the door pocket 21.

In addition, a cover material 42 is provided on the edge of the shielding piece 39c facing the building 10, which can further improve the design. In particular, when the portion 39e of the shielding piece 39c that is on the tip side of the break-off portion 39d is broken off, the broken cross section is covered by the cover material 42, which further improves the design.

In the above embodiment, the shutter unit 1 is attached to a building 10 in which a storm shutter unit 2 is provided with a door pocket 21 on the left side of the sash frame 12, but the door pocket may be provided on the right side of the sash frame. The shutter unit used in this case is reversed from left to right compared to the shutter unit 1 in the above embodiment. Also, the upper blocking member 32a shown in FIG. 6 has a long hole 323a formed so that it can be used regardless of whether the door pocket is located on the left or right side. Also, the lower blocking member used when the door pocket is provided on the right side of the sash frame has a shape reversed from the blocking member 32b.

The above embodiment is intended to facilitate understanding of the present invention, and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents.
