Abstract
Description
[Technical Field]
[0001] The present invention relates to a shutter case.
[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] Furthermore, 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.

In this embodiment, the front portion of the top surface 10 of the upper case plate 1 is made up of a front first portion 100A and a rear second portion 100B, and the second portion 100B is placed on the upper edge 71 of the first horizontal member 7, and the first portion 100A is located forward of the vertical edge 70 of the first horizontal member 7 (see FIG. 4). In this embodiment, the widthwise ends of the top surfaces 10 of the left and right top case plates 1 that form both widthwise ends of the case body are placed so as to overlap the upper edges 32 of the left and right side case plates 3. The rear end portion of the top surfaces 10 may be fixed to the fourth horizontal member 12 (instead of being fixed to the main body W). The top case plate 1 does not have to have the first portion 100A.
[0038] [D-3] Lower case plate mounting structure In this embodiment, the front and bottom portions of the case main body are formed by connecting the front panel 20 and the bottom panel 21 of the lower case panel 2 in the case width direction so that their widthwise ends overlap. The lower case panel 2 has the upper end portion of the front panel 20 abutting the vertical side 70 of the first horizontal member 7, the lower end portion of the front panel 20 abutting the vertical side 82 of the second horizontal member 8, the front end portion of the bottom panel 21 abutting the bottom side 80 of the second horizontal member 8, and the rear end portion of the bottom panel 21 abutting the bottom side 90 of the main body 9A of the third horizontal member 9. The upper end portion of the front panel 20 is fixed to the vertical side 70 of the first horizontal member 7 with screws 22, and the rear end portion of the bottom panel 21 is fixed to the bottom side 90 of the third horizontal member 9 with screws 23. The front panel 20 of the lower case panel 2 is located closer to the body than the front edge 100 of the top surface 10 of the upper case panel 1 and the outer visible edge 31 of the side case panel 3.
[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 portion, and to hide the screws 22 that fix the upper end portions of the front panels 20 of each lower case panel 2 that form the front portion 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.
[0047] [G] Second embodiment The shutter case according to the second embodiment will be described with reference to Figures 20 to 29. Many of the components of the shutter case according to the second embodiment are common to the components of the shutter case according to the previously described embodiments, and the previously described explanations can be used for the common components. The following description will focus on the different configurations.
[0048] [G-1] Upper horizontal member of the case frame As shown in Figure 29, a second upper cross-member 7A is fixed to the first cross-member 7, which is the upper cross-member. That is, the upper cross-member according to the second embodiment is composed of the first cross-member 7 and the second upper cross-member 7A. The first cross-member 7 has a vertical side 70 and an upper side 71 that extends rearward at an incline from the upper end of the vertical side 70, and the inclination of the upper side 71 matches the inclination of the upper surface 10 of the upper case plate 1 and the upper edge 600 of the face portion 60 of the bracket 6. A bent side 72 extending rearward is formed at the lower end of the vertical side 70.
[0049] The second upper cross member 7A comprises an upper edge 74, a front edge 75 extending downward from the front end of the upper edge 74, and a lower edge 76 extending rearward from the lower end of the front edge 75. In the second upper cross member 7A, the upper edge 74 and the lower edge 76 each extend at a right angle to the front edge 75, and the front edge 75, the upper protruding edge 740, and the lower edge 76 form a U-shape in side view, but as described below, the second upper cross member 7A is fixed to the first cross member 7 in an inclined position (the inclination gradients of the upper edge 74 and the upper edge 71 are the same).
[0050] The length dimension (dimension in the case width direction) of the second upper horizontal member 7A is the same as the length dimension of the first horizontal member 7, but the width dimension in the short direction (length dimension in the front-to-back direction) of the top edge 74 of the second upper horizontal member 7A is longer than the width dimension in the short direction (length dimension in the front-to-back direction) of the top edge 71 of the first horizontal member 7. The second upper horizontal member 7A is fixed (welded) so that the rear end of the top edge 74 is aligned with the rear end of the top edge 71 of the first horizontal member 7 and the top edge 74 is overlapped on the top surface of the top edge 71. In this state, the tip side portion of the top edge 74 of the second upper horizontal member 7A forms an upper protruding edge 740 that protrudes forward beyond the vertical edge 70 of the first horizontal member 7.
[0051] The upper edge 74 of the second upper cross-member 7A has the same inclination as the upper edge 71, i.e., the same inclination as the upper surface 10 of the upper case plate 1 and the upper edge 600 of the face portion 60 of the bracket 6. The upper edge 74 of the second upper cross-member 7A extends forward at a downward incline, the front edge 75 extends downward and rearward with respect to the vertical plane, and the lower edge 76 extends rearward at an upward incline with respect to the horizontal plane. The height dimension of the front edge 75 of the second upper cross-member 7A is smaller than the height dimension of the vertical edge 70 of the first cross-member 7, and the tip (rear end) of the lower edge 76 is spaced apart from the vertical edge 70.
[0052] [G-2] Lower case plate As shown in Figure 28, the lower case plate 2 has an L-shape in side view, composed of a front plate 20, which is a rectangular vertical plate, and a bottom plate 21, which is a rectangular horizontal plate. In the lower case plate 2, 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, and 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. An upper edge 24 extending horizontally to the opposite side from the bottom plate 21 is bent from the upper end of the front plate 20. In a more specific embodiment, a hanging portion having an L-shape in side view is formed by a rising portion 25 formed in the central portion of the front panel 20 excluding the upper edge 200 on both ends of the upper end, and an upper edge 24 integrally formed with the upper end of the rising portion 25.
[0053] [G-3] Bracket 27, the bracket 6 is a plate-like member having a surface 60 that is trapezoidal in side view and has an inclined upper edge 600, vertical base edge (rear edge) and tip edge (front edge), and a horizontal lower edge, with a bent piece 61 formed on the base edge. A bearing 62 to which the end of the shaft of the winding shaft is fixed is provided approximately in the center of the inner surface of the surface 60, and an expanded upper guide 63 to which the upper end of the guide rail G is connected is provided on the lower end side and base end side (rear end side) of the inner surface of the surface 60.
[0054] As shown in Figures 26 and 27, an upper connecting piece 64 is provided on the outer surface of the face portion 60 of the bracket 6, extending obliquely along the upper edge 600, and a lower connecting piece 65 made of a long plate is provided on the outer surface of the face portion 60 of the bracket 6, extending horizontally along the lower edge. The upper connecting piece 64 includes 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 is made up of a vertical side 650 that abuts against and is fixed to the surface portion, and a horizontal bottom side 651. The bottom side 651 of the lower connecting piece 65 substantially coincides with the bottom side of the surface portion 60 of the bracket 6.
[0055] As shown in Figure 27, a lower edge 66 extending horizontally inward is formed by bending the lower end of the face portion 60 of the bracket 6. The lower edge 66 is formed and positioned between the mounting piece 8' of the second horizontal member 8 and the mounting piece 9' of the third horizontal member 9. A front connecting edge 67 extending in the height direction of the bracket 6 is provided on the inner surface of the front end of the face portion 60 of the bracket 6. The front connecting edge 67 is an elongated member having an L-shaped cross section formed by a front edge 670 and a prospective edge 671, and the prospective edge 671 is fixed (welded) to the front portion of the inner surface of the face portion 60 of the bracket 6, so that the front edge 670 coincides with the front end of the face portion 60.
[0056] As shown in Figure 27, mounting pieces 7", 8", 9", 12", and 13" are provided on the inner surface of the face portion 60 of the bracket 6. Note that the mounting piece 7" of the first horizontal member 7, which is provided at the upper and front end side of the inner surface of the face portion 60 of the bracket 6, is oriented in a different direction from the mounting piece 7' of the first horizontal member 7 shown in Figure 10. The previous descriptions can be used for the other mounting pieces 8', 9', and 12'.
[0057] [G-4] Side case plate mounting structure The side case plates 3 are fixed to the left and right brackets 6 so as to cover the brackets 6. The above description can be used for details of the configuration of the side case plates 3. As shown in FIG. 13, the side case plates 3 have substantially the same trapezoidal shape in a side view as the brackets 6, and the upper edge 32 abuts against an upper edge 641 of an upper connecting piece 64 fixed to the outside of the face portion 60 of the bracket 6 and is fixed with a screw 36, and the lower edge 33 abuts against a lower edge 651 of a lower connecting piece 65 fixed to the outside of the face portion 60 of the bracket 6 and is fixed with a screw 37 (see FIG. 26). The inner visible edge 35 of the side case plate 3 abuts against a front edge 670 of the front connecting edge 67 of the bracket 6 (see FIG. 25).
[0058] [G-5] Top case plate mounting structure In this embodiment, the upper surface of the case body is formed by connecting multiple upper case plates 1 in the case width direction so that their widthwise ends overlap. The upper case plate 1 has a predetermined portion (second portion 100B) of the front portion of the upper surface 10 placed on the upper edge 74 of the second upper horizontal member 7A, a rear end portion placed on the upper edge 120 of the fourth horizontal member 12, and the rising edge 11 (overlapping portion 11') abutting against the body W, and the rising edge 11 is fixed to the body W with screws 14. In this embodiment, the front portion of the upper surface 10 of the upper case plate 1 consists of a front first portion 100A and a rear second portion 100B, and the first portion 100A and the second portion 100B are placed on the upper edge 74 of the second upper cross member 7A, but the first portion 100A is placed on the upper protruding edge 740 of the upper edge 74 and is located forward of the vertical edge 70 of the first cross member 7 (see Figure 25).
[0059] [G-6] Lower case plate mounting structure In this embodiment, the front and bottom portions of the case body are formed by overlapping the case width direction ends of the front panel 20 and bottom panel 21 of the lower case plate 2 and connecting them in the case width direction (see Figures 20 and 22). The lower case panel 2 is arranged such that the upper end portion of the front panel 20 abuts the vertical edge 70 of the first cross member 7, the lower end portion of the front panel 20 abuts the vertical edge 82 of the second cross member 8, the front end portion of the bottom panel 21 abuts the bottom edge 80 of the second cross member 8, and the rear end portion of the bottom panel 21 abuts the bottom edge 90 of the main body 9A of the third cross member 9. The upper end portion of the front panel 20 is fixed to the vertical edge 70 of the first cross member 7 (the portion of the vertical edge 70 of the first cross member 7 that is located lower than the bottom edge 76 of the second upper cross member 7A) with screws 22, and the rear end portion of the bottom panel 21 is fixed to the bottom edge 90 of the third cross member 9 with screws 23 (see Figures 24 and 25). The front panel 20 of the lower case panel 2 is located closer to the body than the front edge 100 of the top surface 10 of the upper case panel 1 and the outer visible edge 31 of the side case panel 3.
[0060] 25, the upper end of the front panel 20 is located above the gap between the lower edge 76 of the second upper cross member 7A and the vertical edge 70 of the first cross member 7, and the upper edge 24 of the upper end of the front panel 20 is located above the lower edge 76 of the second upper cross member 7A and faces the lower edge 76 at a distance. When the lower case plate 2 is attached, the upper edge 24 of the upper end of the front panel 20 can be hooked onto the lower edge 76 of the second upper cross member 7A, and the lower case plate 2 can be temporarily hooked as necessary when attaching the lower case plate 2, improving workability and preventing the lower case plate 2 from accidentally falling.
[0061] As shown in Figures 21 and 25, 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 are fastened together with the front edge 670 of the front connecting edge 67 (to which the inner visible edge 35 abuts) by screws 27. The side edge 201 of the front panel 20 of the lower case panel 2 is adjacent 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 adjacent to or abuts against the side edge of the lower edge 33 of the side case panel 3. As shown in Figures 21 and 23, the lower panel 21 of the left and right lower case panels 2, which form both widthwise ends of the case body, abut against the lower edge 66 of the bracket 6 so as to overlap it from below and are connected to the lower edge 66 by screws 26.
[0062] [G-7] Upper cover mounting structure In the shutter case of this embodiment, the upper cover 4 covers 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 portion, and is attached across the entire width of the case body so as to hide the screws 22 that fix the second upper cross member 7A and the upper end portions of the front panels 20 of each lower case plate 2 that form the front portion to the vertical edge 70 of the first cross member 7.
[0063] 14 and 25, 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.
[0064] 25, the upper end portion of the inner surface of the vertical side 40 of the upper cover 4 abuts against the upper end portion of the front side 75 of the second upper cross-member 7A. With the upper cover 4 abutting against the second upper cross-member 7A, the upper side 41 of the upper cover 4 is placed on the front end portion of the upper surface 10 of the upper case plate 1, and the front end portions of the upper side 41 and the upper surface 10 are fixed to the upper side 74 of the second upper cross-member 7A and the upper side 71 of the first cross-member 7 with screws 43. When installing the upper cover 4, the upper end portion of the inner surface of the vertical side 40 of the upper cover 4 abuts against the upper end portion of the front side 75 of the second upper cross-member 7A (which may be the tip of the upper protruding side 740), thereby enabling the upper cover 4 to be positioned in the projection direction (front-to-rear direction), improving the ease of installation of the upper cover 4. Here, when attaching the upper cover 4, it is possible to employ a method of positioning by abutting the tip of the lower edge 42 of the upper cover 4 against the front plate 20 (see FIG. 4), but in the lower case 2 according to this embodiment, the front plate 20 is connected in the case width direction so that its end in the case width direction overlaps, and the position of the outer surface of the front plate 20 is not constant, so this method is not suitable for positioning. Also, in the illustrated embodiment, the front edge 75 extends at an angle downward and rearward relative to a vertical plane, but the front edge 75 may be a vertical edge, or may have a portion that bulges or protrudes forward relative to a flat plane, and in these cases, the portion of the inner surface of the vertical edge 40 of the upper cover 4 that abuts against the front edge 75 is not limited to the upper end of the vertical edge 40.
[0065] The upper cover 4 has its front vertical edge 40 covering 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'), the second upper cross member 7A (upper protruding edge 740, front edge 75, lower edge 76), and the heads of the screws 22, and its upper edge 41 covering 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, the upper edge 74 of the second upper cross member 7A, and the upper edge 71 of the first cross member 7 with screws 43.
[0066] 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 cross member 7, and the second upper cross member 7A (upper protruding edge 740, front edge 75, lower edge 76). The screws 43 that secure the upper edge 41 of the upper cover 4 to the front end portion of the top surface 10 of the upper case plate 1 and the upper edge 71 of the first cross member 7 are not visible when viewed from the front of the shutter case (when viewed from below), giving the shutter case a neat appearance and excellent design.
[0067] The upper cover 4 is a long member extending in the case width direction and across the entire width of the shutter case (case body), with the upper edge 41 reaching the widthwise ends of the upper surface 10 of the left and right upper case plates 1 that form both widthwise ends of the case body, and both longitudinal ends of the vertical edge 40 being located in a space 310 (see FIG. 13 ) above the outer visible edge 31 of the side case plate 3. The vertical edge 40 of the upper cover 4 is substantially flush with the outer visible edge 31 of the side case plate 3 (in the illustrated embodiment, the vertical edge 40 protrudes slightly beyond the outer visible edge 31), 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.
[0068] As shown in Figure 25, the bottom edge 42 of the upper cover 4 extends toward the frame toward the front portion (front panel 20) of the case body, but the leading edge (rear end) of the bottom edge 42 is spaced apart from the front panel 20. The front end portion of the top surface 10 of the upper case plate 1 is sandwiched between the underside of the top edge 41 of the upper cover 4 and the upper surface of the top edge 74 of the second upper horizontal member 7A, and there is a risk that rainwater may seep in from the rear end of the top edge 41 of the upper cover 4 onto the underside of the top edge 41. However, even if rainwater does seep in, the rainwater dripping down the inner surface of the vertical edge 40 is guided downward from the leading edge of the bottom edge 42, preventing the rainwater from adhering to the front panel 20 of the lower case plate 2 (which could cause staining of the front panel 20). The mounting structure of the lower cover 5 can be described in detail above.
[0069] [Note] a case framework consisting of left and right brackets fixed to the frame in a corbel-like manner and a plurality of horizontal members connecting the left and right brackets; a top case plate; a lower case plate having a front portion and a bottom portion; an upper cover extending in the width direction of the case; Equipped with The upper end portion of the front surface is fixed to the upper cross member by a fastening member, the upper cover includes a front portion that covers the upper end portion of the front portion and the fastening member (head portion), and an upper portion that covers the front end portion of the upper case plate and is fixed to the front end portion, the upper cross member has a protruding portion that protrudes beyond the upper end portion of the front portion, The front portion of the upper cover abuts against the protrusion.
