Description

[Technical Field]

[0001] The present invention relates to a shutter case. [Background technology]

[0002] A shutter case consists of a case framework consisting of left and right brackets fixed to the main body in a corrugated shape and multiple horizontal members connecting the left and right brackets, and a case body attached to the case framework. Generally, the case body has a top surface, a front surface, a bottom surface, and left and right side surfaces. In some cases, the top surface is formed from a top case plate, and the front surface and bottom surface are formed from a single plate material that is L-shaped or curved in side view. In this case, it is possible to fix the upper end of the front surface to the upper horizontal member with screws (Patent Document 1), but if the screws are exposed on the front of the case, the design of the shutter case will be impaired.

[0003] Depending on the width of the opening where the shutter is installed, the case body may be formed by connecting multiple case unit plates in the case width direction so that their widthwise ends overlap (Patent Document 2, Figure 3). If the rear end of the lower panel of the case unit plate forming the lower surface does not have a folded edge and the rear edge is exposed, or / and if the front end of the upper panel of the case unit plate forming the upper surface does not have a folded edge and the front edge is exposed, the edges of the case unit plates (especially the edges of the overlapping portions) become conspicuous, detracting from the design of the shutter case. Furthermore, if the shutter case is located at a height within reach, it is undesirable for the edges of the case plates to be exposed in a position where they can be touched.

[0016] [A] Overall structure of the shutter case FIG. 1 is a front view of a shutter device equipped with a shutter case according to this embodiment, and FIG. 2 is a cross-section of the same (showing the bottom of the shutter case). FIG. 18 is a perspective view of the shutter case according to this embodiment seen from diagonally above, and FIG. 19 is a perspective view of the shutter case according to this embodiment seen from diagonally below. The shutter case according to this embodiment comprises a case framework attached to a frame W in a corrugated manner, and a case body attached to the case framework. The case body has an upper surface portion, a front surface portion, a lower surface portion, and left and right side surfaces. The upper surface portion, front surface portion, and lower surface portion of the case body are formed from multiple case unit plates. The case unit plates are short relative to the case width, and the case body is formed by connecting multiple case unit plates in the case width direction so that their case width direction ends overlap.

[0017] The case unit according to this embodiment comprises multiple upper case plates 1 and multiple lower case plates 2 that are L-shaped in side view. The width of each upper case plate 1 and each lower case plate 2 is shorter than the overall width of the shutter case. The upper surface of the case body is formed by connecting multiple upper case plates 1 in the width direction of the case with their widthwise ends overlapping. The front and bottom surfaces of the case body are formed by connecting multiple lower case plates 2 in the width direction of the case with their widthwise ends overlapping. The lower case plate 2 has an L-shape in side view consisting of a front plate 20 and a bottom plate 21. The front and bottom surfaces of the case body are formed by connecting the front and bottom surfaces of the case body with their widthwise ends overlapping. In Figures 18 and 19, three upper case plates 1 and three lower case plates 2 are connected in the width direction with their widthwise ends overlapping, but the number of case unit plates (upper case plates 1 and lower case plates 2) is not limited. The side surfaces of the left and right ends in the width direction of the case body are formed by side case plates 3 .

[0018] In this embodiment, the front end portion of the upper surface of the case body includes the front end portion of the upper surface 10 of each upper case plate 1 and the front end portion of the overlapping portion 10', the upper end portion of the front portion of the case body includes the upper end portion of the front plate 20 of each lower case plate 2 and the upper end portion of the overlapping portion 20', and the rear end portion of the lower surface of the case body includes the rear end portion of the lower plate 21 of each lower case plate 2 and the rear end portion of the overlapping portion 21'.

[0019] In this embodiment, an upper cover 4 is attached to the front end of the upper surface of the case body and the upper end of the front surface so as to cover the front end portion of the upper surface and the upper end portion of the front surface. The upper cover 4 covers the front end portion of the upper surface (including the front edge 100 of the upper surface 10) including the front end portion of the overlapping portion 10' of the upper surfaces 10 of the multiple upper case plates 1, and the upper end portions of the front panels 20 of the multiple lower case plates 2 (including the upper end portions of the overlapping portions 20' and the upper edge 200 of the front panels 20), and also has the function of hiding the screws 22 that secure the upper end portions of the front panels 20 of each lower case plate 2 to the case framework (horizontal member 7). The upper cover 4 in this embodiment extends across the entire width of the shutter case (case body) (Figs. 1 and 18).

[0020] In this embodiment, a lower cover 5 is attached to the rear end of the lower surface of the case body so as to cover the rear end portion of the lower surface. The lower cover 5 has the function of covering the rear end portion of the lower surface (including the rear edge 210 of the lower surface plates 21), including the rear end portions of the overlapping portions 21' of the lower surface plates 21 of the multiple lower case plates 2. The length of the lower cover 5 in this embodiment is shorter than the width of the opening (the dimension between the left and right guide rails G) (see FIG. 2A) and shorter than the upper cover 4 (FIGS. 2 and 19).

[0021] A winding shaft (not shown) is provided inside the shutter case so as to span between the left and right brackets 6, and an opening / closing mechanism (not shown) is provided in a protruding manner on one of the brackets 6 (the opening / closing mechanism may be built into the winding shaft), and the shutter curtain S is stored inside the shutter case while wound around the winding shaft, and is guided by guide rails G on the left and right sides of the opening into a vertical position, thereby closing the opening. In the shutter case of this embodiment, if maintenance of the winding shaft, opening / closing mechanism, or their transmission mechanisms becomes necessary, only the lower case plate 2 can be removed by removing the upper cover 4. The shutter to which the present invention is applied may also be a manual shutter that does not use an opening / closing mechanism.

[0022] [B] Shutter case body [B-1]Top part The top surface of the case body according to this embodiment is formed by connecting multiple top case plates 1 in the width direction of the case so that their widthwise ends overlap. As shown in FIG. 11 , the top case plate (case unit plate) 1 comprises a top surface 10 that slopes downward toward the front and a vertical rising edge 11 at the rear end of the top surface 10. The edges of the top case plate 1 comprise a front edge 100 of the top surface 10, left and right side edges 101 of the top surface 10, an upper end 110 of the rising edge 11, and left and right side edges 111 of the rising edge 11. No bent edge is formed at the front end of the top surface 10 of the top case plate 1 according to this embodiment, so the front edge 100 of the top surface 10 is exposed.

[0023] The upper surface of the case body is formed by connecting the upper surface 10 and the rising edge 11 in the width direction of the case so that their widthwise ends overlap. The overlap between the ends of adjacent upper case plates 1 is indicated by overlapping portions 10' and 11' (see Figures 1 and 1A). The front end portion of the upper surface of the case body includes the front end portion of the upper surface 10 of each upper case plate 1 and the front end portion of the overlapping portion 10'. One side edge 101, 111 of the upper case plates 1 located on both sides in the width direction of the case body forms both widthwise end edges of the case body.

[0024] [B-2] Front and bottom parts The front and bottom portions of the case body according to this embodiment are formed by connecting multiple lower case plates 2 (front plate 20, bottom plate 21) in the width direction of the case so that their widthwise ends overlap. As shown in FIG. 12 , the lower case plate 2 (case unit plate) has an L-shape in side view, consisting of the front plate 20, which is a rectangular vertical plate, and the bottom plate 21, which is a rectangular horizontal plate. In the lower case plate 2 according to this embodiment, the front plate 20 and the bottom plate 21 have the same width. The edges of the lower case plate 2 include an upper edge 200 of the front plate 20, left and right side edges 201 of the front plate 20, a rear edge 210 of the bottom plate 21, and left and right side edges 211 of the bottom plate 21. The lower end of the front plate 20 and the front end of the bottom plate 21 form corners of the L-shaped lower case plate 2 in side view. The upper end of the front plate 20 does not have a bent edge, and the upper edge 200 is exposed.

[0025] No bent edge is formed at the rear end of the lower panel 21 of the lower case panel 2 according to this embodiment, and the rear edge 210 of the lower panel 21 is exposed. No raised bent edge is formed at the rear end of the lower panel 21 of the lower case panel 2 according to this embodiment, and the lower panel 21 is completely L-shaped in side view, so that multiple lower case panels 2 can be stacked (when multiple lower case panels of the same shape are stacked, they cannot be stacked if there are bent edges), and multiple lower case panels 2 can be stacked and transported.

[0026] The front and bottom panels 20 and 21 are connected in the width direction of the case so that their widthwise ends overlap, forming the front and bottom panels of the case body. The overlap between the ends of adjacent front panels 20 is indicated by overlapping portion 20' (see Figure 1). The upper end portion of the front panel of the case body includes the upper end portion of the front panel 20 of each lower case panel 2 and the upper end portion of the overlapping portion 20'. The overlap between the ends of adjacent lower panels 21 is indicated by overlapping portion 21' (see Figure 2). The rear end portion of the bottom panel of the case body includes the rear end portion of the lower panel 21 of each lower case panel 2 and the rear end portion of the overlapping portion 21'. One side edge 201, 211 of the front panel 20 and the bottom panel 21 of the lower case panel 2 located on both sides in the width direction of the case body forms both widthwise ends of the case body.

[0027] [B-3] Side case plate The left and right side surfaces of the case body in the width direction are formed by side case plates 3. As shown in FIG. 13, side case plate 3 includes a trapezoidal surface portion 30, a front edge (outer edge) 31 at the front end of surface portion 30, a slanted upper edge 32, and a horizontal lower edge 33. The outer edge 31, upper edge 32, and lower edge 33 have the same width. Side case plate 3 also includes a front projected edge 34 extending from the outer edge 31 toward the body, and an inner projected edge 35 extending inward from the end of the front projected edge 34 on the body side. The height of the outer edge 31 is smaller than the height of the front end of surface portion 30, and the upper end of the outer edge 31 does not reach the front end of the upper edge 32, forming a space 310. Both longitudinal ends of upper cover 4 are located in this space 310 (see FIG. 4). The height dimensions of the outer visible edge 31 and the front visible edge 34 are the same, and the height dimension of the inner visible edge 35 is smaller than the height dimensions of the outer visible edge 31 and the front visible edge 34.

[0028] [C] Shutter case frame The case framework according to this embodiment is made up of left and right brackets 6 fixed to the body W in a corrugated manner, and multiple cross members (so-called angle members) connecting the left and right brackets 6. The brackets 6 are fixed to the body W with screws (not shown) in a state where a bent piece 61 on the base end side (rear end side) of the bracket 6 is abutted against the body W. The case framework according to this embodiment includes five cross members: a first cross member 7, a second cross member 8, a third cross member 9, a fourth cross member 12, and a fifth cross member 13.

The upper connecting piece 64 comprises a vertical edge 640 that abuts and is fixed to the face portion 60, and an inclined upper edge 641. The upper edge 641 of the upper connecting piece 64 approximately coincides with the upper edge 600 of the face portion 60 of the bracket 6. In this embodiment, the upper edge 641 of the upper connecting piece 64 is located slightly below the upper edge 600 of the face portion 60 of the bracket 6, so that the upper edge 32 of the side case plate 3 rests on the upper edge 641, and the upper surface 10 of the upper case plate 1 rests on the upper edge 600 of the face portion 60 of the bracket 6 and the upper edge 32 of the side case plate 3. The lower connecting piece 65 consists of a vertical side 650 that abuts against and is fixed to the face portion, and a horizontal bottom side 651. The bottom side 651 of the lower connecting piece 65 roughly coincides with the bottom side of the face portion 60 of the bracket 6. The upper connecting piece 64 and the lower connecting piece 65 are both elongated members that extend in the width direction (projection direction) of the face portion 60 of the bracket 6.

[0039] In this embodiment, the widthwise ends of the front panel 20 of the left and right lower case panels 2, which form both widthwise ends of the case body, abut against the inner visible edge 35 of the side case panel 3, and the side edge 201 of the front panel 20 is close to or abuts against the front visible edge 34 of the side case panel 3. The lower surfaces of the lower panel 21 of the left and right lower case panels 2, which form both widthwise ends of the case body, are substantially flush with the lower surface of the lower edge 33 of the side case panel 3, and the side edge 211 of the lower case panel 2 is close to or abuts against the side edge of the lower edge 33 of the side case panel 3. The side edge 211 may extend toward the side case panel 3 and be inserted between the lower edge 33 and the lower edge 651, or a plate extending toward the lower case panel 2 may be provided on the lower edge 33 so that the plate overlaps the end of the lower panel 21 (on the case interior side).

[0040] [E] Top cover In the shutter case of this embodiment, the upper cover 4 is attached across the entire width of the case body so as to cover the front end portion (including the front edge 100) of the upper surface of the case body and the upper end portion (including the upper edge 200) of the front surface, and to hide the screws 22 that fix the upper end portions of the upper panel of each lower case plate 2 that forms the front surface to the vertical edge 70 of the first cross member 7.

[0041] 4 and 14, the upper cover 4 is composed of a vertical side 40, an inclined upper side 41 that extends from the upper end of the vertical side 40 at an angle upward toward the rear, and a lower side 42 that extends horizontally toward the rear from the lower end of the vertical side 40. The inclination of the upper side 41 of the upper cover 4 is approximately the same as the inclination of the upper surface 10 of the upper case plate 1, the upper side 71 of the first horizontal member 7, and the upper edge 600 of the face portion 60 of the bracket 6. The projected dimension (dimension in the front-to-rear direction) of the upper side 41 is larger than the projected dimension (dimension in the front-to-rear direction) of the lower side 42, and is configured to cover not only the first portion 100A including the front edge 100, but also at least a portion (front side) of the second portion 100B. Here, in this embodiment, the "front portion" of the upper surface 100 refers to the first portion 100A (including the front edge 100) and the second portion 100B in Figure 4, and the "front end portion" of the upper surface 100 refers to the first portion 100A (including the front edge 100) and a part of the second portion 100B (the portion overlapping with the upper side 41) in Figure 4.

[0042] The upper cover 4 has a front vertical edge 40 that covers the upper end portion of the front part of the case body (the upper end portion of each front panel 20, including the upper end portion of the overlapping portion 20') and the heads of the screws 22, and an upper edge 41 that covers the front end portion of the upper surface part of the case body (the front end portion of the upper surface 10 of each upper case plate 1, including the front end portion of the overlapping portion 10') and is fixed to the front end portion of the upper surface part and the upper edge 71 of the first cross member 7 with screws 43.

[0043] The upper cover 4 conceals the screws 22 that secure the upper end portion of the front panel 20 of the lower case plate 2 to the vertical edge 70 of the first horizontal member 7. The screws 43 that secure the upper edge 41 of the upper cover 4 to the front end portion of the upper surface 10 of the upper case plate 1 and to the upper edge 71 of the first horizontal member 7 are not visible when the shutter case is viewed from the front (when viewed from below), giving the shutter case a neat appearance and excellent design.

[0044] The upper cover 4 according to this embodiment is a long member extending in the case width direction across the entire width of the shutter case (case body), with the upper edge 41 reaching the widthwise ends of the upper surfaces 10 of the left and right upper case plates 1 that form both widthwise ends of the case body (FIGS. 1 and 18), and both longitudinal ends of the vertical edge 40 being located in the space 310 above the outer visible edge 31 of the side case plate 3. The lower edge 42 of the upper cover 4 extends toward the body of the case, toward the front portion (front plate 20) of the case body (the tip of the lower edge 42 may be close to or abut against the front plate 20), and the vertical edge 40 of the upper cover 4 is substantially flush with the outer visible edge 31 of the side case plate 3, and the upper ends of the outer visible edge 31 and the front visible edge 34 are close to or abut against the underside of the lower edge 42 of the upper cover 4.

[0045] [F] Lower cover In this embodiment, a lower cover 5 extending in the case width direction is attached to the rear end of the lower panel 21 of the lower case plate 2 so as to cover the rear end portion including the rear edge 210 of the lower panel 21 (including the rear end portion of the overlapping portion 21'). As shown in FIGS. 6 and 15, the lower cover 5 has a horizontal lower side 50 and a vertical rising side 51, forming an L-shape in a side view. The length of the lower cover 5 according to this embodiment is shorter than the width of the opening and shorter than the upper cover 4 (FIGS. 2 and 19).

[0046] The lower cover 5 is attached by fixing the lower edge 50 to the rear end portion of the lower plate 21 and the lower edge 90 of the third horizontal member 9 with screws 52 so that the lower edge 50 covers the rear end portion (including the rear end portion of the overlapping portion 21') of the lower panel 21 of the lower case panel 2. The lower end portions of the rising edges 51 of the lower cover 5 are close to or abut against the rear end edges 210 (including the rear end edges 210 of the overlapping portions 21') of the lower panel 21 of each lower case panel 2. In this embodiment, no bent edge is formed at the rear end of the lower panel 21 of the lower case panel 2, and the horizontally extending rear end edge of the lower panel 21 exposes the cut surface of the plate material, and the lower end portion of the rising edges 51 of the lower cover 5 covers the cut surface. In addition, when the shutter case consists of one lower case plate 2 and one upper case plate 1, the lower cover 5 may cover the rear edge 210 of the lower plate 21 of the lower case plate 2, and the upper cover 4 may cover the upper edge 200 of the front plate 20 and the front edge 100 of the upper surface 10 of the upper case plate 1.
