Abstract
Description
Technical Field
[0006] , ,
[0001] The present invention relates to a connection structure between a first surface portion of a first member and a second surface portion of a second member by a joint.
Background Art
[0002] Awnings provided so as to project from the outer wall of a building are known (Patent Document 1). However, when installing a relatively large awning on the outer wall of a building, it is necessary to assemble and install a plurality of awning components in a factory or on-site. When connecting a plurality of awning components, typically, direct connection using screws, connection using screws and connecting members, etc. can be considered. However, in any case, screw fastening work is required, and there is a problem in terms of design because the heads of the screws are exposed outside.
[0003] Also, in the case of a relatively large awning, there may be a case where an awning component extending in the viewing direction and an awning component extending in the prospecting direction abut at a substantially right angle to form an outer corner portion or an inner corner portion.
[0004] Therefore, a connection structure for the outer corner portion or the inner corner portion of the awning that does not use screws suitable for connecting the components and has good workability and designability for connecting the surface portions is desired.

[0014] [A] Overall structure of the canopy As shown in Figure 1, the canopy 1 according to this embodiment is a relatively large canopy 1 installed on the exterior wall of a building. Figure 1A is a side view of Figure 1 (viewed from the facing direction X), and Figure 1B is a front view of Figure 1 (viewed from the depth direction Y). As shown in Figure 2, the building frame W to which the canopy 1 is attached comprises, in cross-sectional view, a horizontal upper wall W1, a vertical wall W2, and a horizontal lower wall W3. The illustrated building frame W is illustrative, and the shape of the building frame W to which the canopy 1 is attached is not limited.
[0015] The canopy 1 consists of an upper part (upper cover) 2, a front part (front cover) 3, and a lower part (lower cover) 4. In this embodiment, the upper part 2, front part 3, and lower part 4 are formed from aluminum profiles. The upper end of the front part 3 is connected to the upper part 2, and the lower end of the front part 3 is connected to the lower part 4, so that the canopy unit is formed from the upper part 2, front part 3, and lower part 4. The ends of the upper part 2, front part 3, and lower part 4 are connected in a second direction β (front-to-back direction in the case of the upper part 2 and front part 3, and up-to-down direction in the case of the front part 3) that is perpendicular to a first direction α which is the width direction or lateral width direction, to form the canopy unit (see Figure 7 for the first direction α and the second direction β). Specifically, the upper and lower ends of the front part 3 in the second direction β, which is the height direction, are connected to the upper part 2 and lower part 4, respectively, to form the canopy unit.
[0016] In each canopy component unit, the upper surface 2, front surface 3, and lower surface 4 that form the same canopy component unit are approximately the same width, and the width dimension is shorter than the dimension of the wall surface of the building frame W to which the canopy 1 is attached. Multiple canopy component units are connected in the width direction (visible direction X or depth direction Y) to form the canopy 1 (Figures 1, 1A, and 1B). When a canopy component unit extends in the visible direction X, the first direction α and the visible direction X coincide, and when a canopy component unit extends in the depth direction Y, the first direction α and the depth direction Y coincide.
[0017] In Figures 1, 1A, and 1B, the canopy unit 1A consists of an upper section 2A, a front section 3A, and a lower section 4A; the canopy unit 1B consists of an upper section 2B, a front section 3B, and a lower section 4B; the canopy unit 1C consists of an upper section 2C, a front section 3C, and a lower section 4C; the canopy unit 1D consists of an upper section 2D, a front section 3D, and a lower section 4D; the canopy unit 1E consists of an upper section 2E, a front section 3E, and a lower section 4E; and the canopy unit 1F consists of an upper section 2F, a front section 3F, and a lower section 4F.
[0018] Canopy unit 1A and canopy unit 1B are adjacent to each other and extend in the visible direction X, and canopy unit 1A and canopy unit 1B are connected in the visible direction X by the first joint 5 (see Figure 20). As shown in Figures 1 and 1B, canopy unit 1A and canopy unit 1D are adjacent to each other and extend in the visible direction X, and are connected in the visible direction X by the first joint 5 (see Figure 20). As shown in Figures 1 and 1A, canopy unit 1E and canopy unit 1F are adjacent to each other and extend in the depth direction Y, and are connected in the depth direction by the first joint 5 (see Figure 20).
[0019] In this embodiment, in canopy units installed adjacent to each other in the visible direction X or depth direction Y, the front portion 3 and the bottom portion 4 that form the same canopy unit are connected at the factory, the assembly of the front portion 3 and the bottom portion 4 and the top portion 2 are transported to the site, the assembly is attached to the building frame W, and the top portion 2 is attached to the assembly. Taking canopy unit 1A as an example, the front portion 3A and the bottom portion 4A are connected at the factory, the assembly of the front portion 3A and the bottom portion 4A is attached to the building frame W (vertical wall W2, bottom wall W3) at the site, and the top portion 2A is attached to the mounting piece 34 at the upper end of the front portion 3A. The connection (using the first joint 5) between canopy units installed adjacent to each other in the visible direction X or depth direction Y (canopy units 1A and 1B, canopy units 1A and 1D, canopy units 1E and 1F) is performed at the site.
[0020] The canopy unit 1B extends in the visible direction X, and the canopy unit 1C extends in the depth direction Y. The canopy units 1B and 1C are connected by a second joint 6 (see Figure 21) and a third joint 7 (see Figure 22) to form a corner section (outside corner). In this embodiment, the formation of the outside corner using the second joint 6 and the third joint 7 is carried out in the factory, and the canopy units 1B and 1C are transported to the site in a connected state (excluding the upper sections 2B and 2C). The upper sections 2B and 2C are installed on site.
[0021] The canopy unit 1D extends in the visible direction X, and the canopy unit 1E extends in the depth direction Y. The canopy units 1D and 1E are connected by a fourth joint 8 (see Figure 23) and a fifth joint 9 (see Figure 24) to form a corner section (inner corner). In this embodiment, the formation of the inner corner using the fourth joint 8 and the fifth joint 9 is performed in the factory, and the canopy units 1D and 1E are transported to the site in a connected state (excluding the upper sections 2D and 2E). The upper sections 2D and 2E are installed on site.
[0022] [B] Configuration of the canopy unit As described above, the canopy unit consists of an upper part 2, a front part 3, and a lower part 4. Multiple canopy units 1A to 1F are connected via joints 5 to 9 in the visible direction X and the depth direction Y to form the canopy 1.
[0023] [B-1]Top part As shown in Figures 2 and 3, the upper surface portion 2 of the canopy unit consists of an inclined surface portion 20 that slopes downward toward the front, a vertical front surface 21 at the front end of the inclined surface portion 20, a vertical rear surface 22 at the rear end of the inclined surface portion 20, a horizontal lower surface 23 connecting the lower ends of the front surface 21 and the rear surface 22, and a horizontal extension piece 24 on the rear end side of the inclined surface portion 20.
[0024] Opposite the front end of the lower surface of the inclined surface portion 20, a receiving piece 25 made of a projection is formed on the upper part of the inner surface (rear surface) of the front surface 21, extending over the entire width of the inclined surface portion 20. Opposite the rear end of the lower surface of the inclined surface portion 20, a receiving piece 26 made of a projection is formed on the upper part of the front surface of the rear surface 22, extending over the entire width of the inclined surface portion 20. The receiving pieces 25 and 26 face each other in the front-rear direction (second direction β). A groove G extending in the width direction (first direction α) across the entire width of the inclined surface portion 20 is formed between the receiving piece 25 and the back surface of the front end of the inclined surface portion 20. A groove G extending in the width direction (first direction α) across the entire width of the inclined surface portion 20 is formed between the receiving piece 26 and the back surface of the rear end of the inclined surface portion 20. As will be described later, both ends of this groove G form the insertion receiving portions (14, 15) of the first joint 5. When describing the upper surface portion 2 of individual canopy components 1A to 1F, they can be represented by adding A to F after the numbers 2, 20, 21, 22, 23, 24, 25, and 26 that represent each element (see Figure 3).
[0025] [B-2] Front part As shown in Figures 2 and 3, the front portion 3 of the canopy unit consists of a vertical surface portion 30 extending in the height direction, an upper edge 31 extending horizontally backward from the upper end of the vertical surface portion 30, a lower edge 32 extending horizontally backward from the lower end of the vertical surface portion 30, a rising edge 33 at the rear end of the upper edge 31, and a mounting piece 34 that is integrally formed on the rising edge 33 and has a U-shape in side view.
[0026] A receiving piece 35, consisting of a downward-sloping projection, is formed over the entire width of the vertical surface portion 30, at the front end of the lower surface of the upper edge 31, opposite the rear surface of the upper end of the vertical surface portion 30. A receiving piece 36, consisting of a rising projection, is formed over the entire width of the vertical surface portion 30, at the front end of the upper surface of the lower edge 32, opposite the rear surface of the lower end of the vertical surface portion 30. The receiving pieces 35 and 36 face each other in the height direction (second direction β). A groove G extending in the width direction (first direction α) over the entire width of the vertical surface portion 30 is formed between the receiving piece 35 and the back surface of the upper end of the vertical surface portion 30. A groove G extending in the width direction (first direction α) over the entire width of the vertical surface portion 30 is formed between the receiving piece 36 and the back surface of the lower end of the vertical surface portion 30. As will be described later, both ends of this groove G form insertion receiving portions (14, 15) of the first joint 5, the second joint 6, and the fourth joint 8. When describing the front section 3 of individual canopy units 1A to 1F, each element can be represented by adding A to F after the numbers 3, 30, 31, 32, 33, 34, 35, and 36 (see Figure 3).
[0027] [B-3] Bottom part As shown in Figures 2 and 3, the lower surface portion 4 of the canopy unit consists of an inclined surface portion 40 that slopes downward toward the front, a hanging piece 41 at the front end of the inclined surface portion 40, and a connecting piece 42 that extends horizontally toward the rear from the rear end of the inclined surface portion 40.
[0028] Opposite the lower surface of the front end of the inclined surface portion 40, a receiving piece 43 consisting of a projection is formed at the upper end of the inner surface of the hanging piece 41, extending across the entire width of the inclined surface portion 40. Opposite the lower surface of the rear end of the inclined surface portion 40, a receiving piece 44 consisting of a projection with an L-shape in cross-section is formed, extending across the entire width of the inclined surface portion 40. The receiving pieces 43 and 44 face each other in the front-rear direction (second direction β). A groove G extending in the width direction (first direction α) across the entire width of the inclined surface portion 40 is formed between the receiving piece 43 and the back surface of the front end of the inclined surface portion 40, and a groove G extending in the width direction (first direction α) across the entire width of the inclined surface portion 40 is formed between the receiving piece 44 and the back surface of the rear end of the inclined surface portion 40. As will be described later, the receiving pieces 43 and 44 form the insertion receiving portions (14, 15) of the first joint 5, the third joint 7, and the fifth joint 9. When describing the lower surface portion 4 of individual canopy components 1A to 1F, they can be represented by adding A to F after the numbers 4, 40, 41, 42, 43, and 44 that represent each element (see Figure 3).
[0029] [B-4] Attachment of the canopy component unit to the building structure In this embodiment, the assembly of the front section 3 and the bottom section 4 is formed in the factory by bringing the lower edge 32 of the lower end of the front section 3 into contact with the front half of the connecting piece 42 of the bottom section 4 and fixing it with a screw S1, and this assembly and the top section 2 are transported to the site. The mounting piece 34 at the upper end of the front section 3 consists of a horizontal upper edge 340, a horizontal lower edge 341, and a vertical rear edge 342. The upper edge 340 is aligned with the same height as the upper wall W1, the rear edge 342 is fixed to the vertical wall W2 with a screw S2, and the rear half of the connecting piece 42 of the bottom section 4 into contact with the lower surface of the bottom wall W3 and fixed with a screw S3, thereby attaching the assembly to the building frame W. The rear end portion of the lower surface 23 and the rear surface 22 of the upper surface 2 are brought into contact with the corner formed by the upper edge 31 and rising edge 33 of the front surface 3, the front half of the extension piece 24 of the upper surface 2 is brought into contact with the upper edge 340 of the mounting piece 34, and the rear half of the extension piece 24 is brought into contact with the upper wall W1, and the extension piece 24 is fixed to the upper edge 340 with screws S4. The order of attachment of the canopy unit to the building frame W is not limited to the above description.
[0030] After attaching the first canopy unit to the building frame W, the second canopy unit is connected adjacent to the first canopy unit and attached to the building frame W, and the third canopy unit is connected adjacent to the second canopy unit and attached to the building frame W. When the canopy units are connected in a straight line, the first joint 5 is used. When the canopy units are connected butted at a right angle, the second joint 6 and the third joint 7 are used to form an outer corner, and the fourth joint 8 and the fifth joint 9 are used to form an inner corner.
[0031] [B-5] Edge of the canopy component unit As shown in Figure 4, when facing the upper surface 2, the edge in the width direction of the upper surface 2 (which will be the visible direction X or the depth direction Y depending on the mounting method of the canopy unit) consists of the edge 200 of the inclined surface 20, the edge 210 of the front surface 21, and the edge 230 of the lower surface 23, as seen in a front or side view of the canopy unit. These edges 200, 210, and 230 form the edge of the upper surface 2. When facing the front surface 3, the edge in the width direction of the front surface 3 (which will be the visible direction X or the depth direction Y depending on the mounting method of the canopy unit) consists of the edge 300 of the vertical surface 30, as seen in a front or side view of the canopy unit. The edge 300 forms the edge of the front surface 3. When facing the lower surface 4, the edge in the width direction of the lower surface 4 (which will be the visible direction X or the depth direction Y depending on the mounting method of the canopy unit) consists of the edge 400 of the inclined surface 40 and the edge 410 of the hanging piece 41 in a front view or side view of the canopy unit. These edges 400 and 410 form the edge of the lower surface 4 (consisting of a common straight line). As shown in Figure 4, the upper surface 2, front surface 3, and lower surface 4 that form the same canopy unit have the same width, and the width direction edges 200, 210, 230, 300, 400, and 410 are located on a common vertical plane and form a straight line when facing each other. In addition, the abutting edges of the surfaces that form the outer corners and inner corners are inclined edges in a plan view (see edges 300' and 400' in Figures 12 to 14 and 16 to 18).
[0032] [C] Connecting structure of canopy component unit (first embodiment) [C-1] Overview The connection structure of the canopy components according to the first embodiment is for cases where the canopy components are connected in a straight line (i.e., excluding the outer corners and inner corners), and specifically, adjacent canopy components in the facing direction X or depth direction Y (canopy component 1A and canopy component 1B, canopy component 1A and canopy component 1D, canopy component 1E and canopy component 1F) are connected using the first joint 5.
[0033] In the connection structure between the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) of the first member (canopy unit 1A) and the second surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) of the second member (canopy unit 1B) by the first joint 5, a wedge-shaped first insertion portion 50 is formed in the first half 5A of the first joint 5, and a second insertion portion 51 is formed in the second half 5B. The first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) has a first surface and a first back surface, and a first insertion receiving portion 14 into which the first insertion portion 50 is inserted is formed on the first back surface. The second surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) has a second surface and a second back surface, and a second insertion receiving portion 15 into which the second insertion portion 51 is inserted is formed on the second back surface.
[0034] The procedure for connecting using the first joint 5 is as follows: Insert the wedge-shaped first insertion portion 50 of the first joint 5 into the first insertion receiving portion 14 of the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40), causing the second insertion portion 51 to protrude from the edges 200, 300, and 400 of the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) (see Figures 4, 5, 7, 9, and 10). The recessed portion 51 is inserted into the second insertion receiving portion 15 of the second surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40), bringing the edges 200, 300, and 400 of the second surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) close to or in contact with the edges 200, 300, and 400 of the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) (see Figure 1A).
[0035] With the first insertion portion 50 of the first joint 5 fitted into the first insertion receiving portion 14 of the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40), and the second insertion portion 51 inserted into the second insertion receiving portion 15 of the second surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40), the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) and the second surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) are in close proximity or in contact with each other, and the first surface and the second surface form substantially the same plane.
[0036] [C-2] Insertion receiving part In this embodiment, the first insertion receiving portion 14 and the second insertion receiving portion 15 consist of a pair of grooves G formed opposite each other on the first and second sides of the second direction β perpendicular to the first direction α of the surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) (see Figure 7). In this embodiment, a pair of receiving pieces (25, 26; 35, 36; 43, 44) are formed on the first and second sides of the second direction β on the back surface of the surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) over the entire width (width), and a groove G is formed between the receiving pieces and the back surface of the surface portion over the entire width of the surface portion. The first insertion portion 50 is inserted into one end of the groove G in the first direction α, and the second insertion portion 51 is inserted into the other end. In other words, as shown in Figure 7, the receiving pieces (receiving pieces 35, 36), the back surface of the surface portion (vertical surface portion 30), and one end of the groove portion G form the first insertion receiving portion 14, and the other end of the groove portion G forms the second insertion receiving portion 15. The first insertion receiving portion 14 and the second insertion receiving portion 15 only need to have a width dimension corresponding to the insertion depth of the first insertion portion 50 and the second insertion portion 51 at both ends in the width direction (first direction α) of the surface portion, and do not need to be formed over the entire width.
[0037] [C-3] 1st Joint The first joint 5 is a long element that extends in the longitudinal direction of the edges 200, 300, and 400 of each surface (inclined surface 20, vertical surface 30, inclined surface 40), with the first side in the shorter direction being the first half 5A and the second side being the second half 5B. A wedge-shaped first insertion part 50 is formed in the first half 5A of the first joint 5, and a second insertion part 51 is formed in the second half 5B.
[0038] The first joint 5 according to this embodiment is obtained by bending a steel plate of a predetermined shape. The right diagram of Figure 20 shows the first joint 5, and the left diagram of Figure 20 shows the state before the rising piece 55 is bent. As shown in Figure 20, the first insertion part 50 includes an inclined first folded piece 52 formed by folding the first side portion of the plate material inward, and the second insertion part 51 includes a second folded piece 53 formed by folding the second side portion of the plate material inward and then crushing and bending it, with the surface portion between the first folded piece 52 and the second folded piece 53 forming the base 54. The wedge-shaped first insertion part 50 is formed from the first side portion of the base 54 and the first folded piece 52, and the crushed and bent second insertion part 51 is formed from the second side portion of the base 54 and the second folded piece 53. Rising pieces 55 are bent and formed at both ends in the longitudinal direction of the first folded piece 52, and the rising pieces 55 function as positioning stoppers. To facilitate insertion of the first insertion portion 50 into the first insertion receiving portion 14, both ends of the first insertion portion 50 in the longitudinal direction are notched at an angle. To facilitate insertion of the second insertion portion 51 into the second insertion receiving portion 15, both ends of the second insertion portion 51 in the longitudinal direction are notched at an angle. The first joint 5 may be formed from a material other than a metal plate, for example, resin.
[0039] [C-4] Connection structure Referring to Figures 9 and 10, the case in which adjacent canopy components are connected in a straight line using the first joint 5 (5a, 5b, 5c) will be described. The wedge-shaped first insertion portion 50 of the first joint 5 is fitted into the first insertion receiving portion 14 of the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) of one canopy component 1B, and the second insertion portion 51 protrudes from the edges 200, 300, 400 of each surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40).
[0040] Next, the other canopy unit 1A is slid closer to the one canopy unit 1B, while inserting the second insertion portion 51 protruding from the edges 200, 300, 400 of the one canopy unit 1B into the second insertion receiving portion 15 of the second surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) of the canopy unit 1A, so that the edges 200, 300, 400 of the second surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) come into close proximity to or contact with the edges 200, 300, 400 of the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40).
[0041] At this time, the surface of the first surface (inclined surface 20, vertical surface 30, inclined surface 40) of the canopy unit 1A and the surface of the second surface (inclined surface 20, vertical surface 30, inclined surface 40) of the canopy unit 1B form substantially the same plane.
[0042] When the wedge-shaped first insertion portion 50 of the first joint 5 is inserted into the groove G of the first insertion receiving portion 14, the first folded-back piece 52 is compressed within the groove G during insertion. The first folded-back piece 52 is elastic, and the return force of the compressed first folded-back piece 52 presses against the inner surface of the receiving piece 36 (see Figure 6), thereby preventing the first insertion portion 50 from coming out of the first insertion receiving portion 14 and fixing it in place. Furthermore, by inserting the first insertion portion 50 until the rising piece 55 abuts against the edge of the receiving piece 36 (see Figure 6), the first insertion portion 50 is fixed in a position relative to the first insertion receiving portion 14.
[0043] The first joint 5 is positioned by fixing the first insertion portion 50 to one of the canopy components, so the position of the second insertion portion 51 protruding from the edges 200, 300, and 400 of the first surface portion (inclined surface portion 20, vertical surface portion 30, inclined surface portion 40) is fixed, preventing the first joint 5 from moving or shifting when the second insertion portion 51 is inserted into the second insertion receiving portion 15. The second insertion portion 51 of the first joint 5 is equipped with a flattened and bent second folded piece 53, which is thinner than the groove width of the groove portion G of the second insertion receiving portion 15, resulting in good workability when inserting the second insertion portion 51 into the second insertion receiving portion 15. On the other hand, it is sufficient for the second insertion portion 51 to be inserted into the second insertion receiving portion 15, and it is not necessary for the second insertion portion 51 to be fitted into the second insertion receiving portion 15.
[0044] In this embodiment, first joints 5a to 5c of different lengths are provided to correspond to the lengths of the edges 200, 300, and 400 of each surface (inclined surface 20, vertical surface 30, and inclined surface 40) (dimensions in the second direction β of the inclined surface 20, vertical surface 30, and inclined surface 40). As shown in Figure 4, the first insertion portion 50 of the first half 5A of the first joint 5a is inserted into the first insertion receiving portion 14 from the widthwise end 200 of the inclined surface 20 of the upper surface 2 of the canopy unit 1A, the first insertion portion 50 of the first half 5A of the first joint 5b is inserted into the first insertion receiving portion 14 from the widthwise end 300 of the vertical surface 30 of the front surface 3 of the canopy unit 1A, and the first insertion portion 50 of the first half 5A of the first joint 5c is inserted into the first insertion receiving portion 14 from the widthwise end 400 of the inclined surface 40 of the lower surface 4 of the canopy unit 1A.
[0045] In this embodiment, the protrusion amount of the second insertion portion 51 of the first joint 5b is greater than the protrusion amount of the second insertion portions of the first joints 5a and 5c. When connecting one canopy unit to the other canopy unit, the second insertion portion 51 of the first joint 5b, which has a larger protrusion amount, is inserted first into the second insertion receiving portion 15 of the corresponding second surface portion (vertical surface portion 30). This improves work efficiency compared to inserting adjacent second insertion portions 51 with the same protrusion amount into the second insertion receiving portion 15 simultaneously (which requires aligning both before insertion). Note that there may be one or more first joints with a larger protrusion amount of the second insertion portion 51, and this can be appropriately determined depending on the number and shape of the first joints. Also, if the same canopy unit has multiple first joints, the protrusion amounts may be reduced sequentially from the end (for example, in the order of 5a, 5b, 5c).
[0046] As shown in Figure 1A, the edges 200, 210, 230, 300, 400, and 410 of the upper surface 2 (inclined surface 20, front surface 21, lower surface 23), front surface 3 (vertical surface 30), and lower surface 4 (inclined surface 40, hanging piece 41) of the canopy unit 1E are spaced apart from the edges 200, 210, 230, 300, 400, and 410 of the upper surface 2 (inclined surface 20, front surface 21), front surface 3 (vertical surface 30), and lower surface 4 (inclined surface 40, hanging piece 41) of the adjacent canopy unit 1F, and the base 54 portion of the first joint 5 forms the joint J between the adjacent canopy units.
[0047] [D] Connecting structure of canopy component unit (second embodiment) [D-1] Overview As shown in Figures 1, 1B, and 11-14, an external corner is formed by canopy unit 1B and canopy unit 1C. The connecting structure of the canopy unit according to the second embodiment connects the two canopy units (canopy unit 1B and canopy unit 1C) that form the external corner using a second joint 6 and a third joint 7. As shown in Figures 1 and 12, canopy unit 1B extends in the visible direction X, and canopy unit 1C extends in the depth direction Y, and canopy unit 1B and canopy unit 1C abut together to form an external corner.
[0048] The vertical surface portion 30B of the canopy unit 1B and the vertical surface portion 30C of the canopy unit 1C form approximately a right angle. The inclined surface portion 40B of the canopy unit 1B and the inclined surface portion 40C of the canopy unit 1C form approximately a right angle in plan view. In this embodiment, no joint is used between the upper surface portion 2B of the canopy unit 1B and the upper surface portion 2C of the canopy unit 1C, which form the outer corner.
[0049] [D-2] Connecting structure by the second joint As shown in Figure 21, the second joint 6 is a long element extending in the longitudinal direction (height direction) of the vertical surface portion 30 of the front portion 3, and consists of a first half portion 6A and a second half portion 6B that form approximately a right angle in cross-section, with a wedge-shaped first insertion portion 60 formed in the first half portion 6A and a wedge-shaped second insertion portion 61 formed in the second half portion 6B.
[0050] The second joint 6 according to this embodiment is obtained by bending a steel plate of a predetermined shape. The first insertion portion 60 is formed from a first base 62 and a second base 63 bent at a right angle, and an inclined first folded piece 64 formed by folding the first base 62 inward. The second insertion portion 61 is formed from the second base 63 and an inclined second folded piece 65 formed by folding the second base 63 inward. To facilitate insertion of the first insertion portion 60 into the first insertion receiving portion 14, both ends of the first insertion portion 60 in the longitudinal direction are notched in an inclined manner. To facilitate insertion of the second insertion portion 61 into the second insertion receiving portion 15, both ends of the second insertion portion 61 in the longitudinal direction are notched in an inclined manner. The second joint 6 may also be formed from a material other than a metal plate, for example, resin.
[0051] As shown in Figures 12 and 13, the vertical surface portion 30B of the canopy unit 1B and the vertical surface portion 30C of the canopy unit 1C are connected by the second joint 6. The first insertion receiving portion 14 and the second insertion receiving portion 15 can be described by referring to the description of the first embodiment. At the outer corner, the widthwise edges 300' of the vertical surface portion 30B of the canopy unit 1B and the vertical surface portion 30C of the canopy unit 1C are inclined edges, and the edges of the receiving pieces 36B and 36C are also inclined edges, and these inclined edges form a butt joint.
[0052] The connection structure of the first surface (vertical surface 30C) of the first member (canopy unit 1C) and the second surface (vertical surface 30B) of the second member (canopy unit 1B) by the second joint 6 will be described. The wedge-shaped first insertion portion 60 of the second joint 6 is fitted into the first insertion receiving portion 14 formed on the back surface of the vertical surface 30C of the canopy unit 1C. The wedge-shaped second insertion portion 61 of the second joint 6 is fitted into the second insertion receiving portion 15 formed on the back surface of the vertical surface 30B of the canopy unit 1B. The edges 300' of the vertical surface 30B of the canopy unit 1B and the vertical surface 30C of the canopy unit 1C are close together or in contact, and in the illustrated configuration, the edges 300' are in contact with each other to form a butt joint. Similar to the first insertion portion 50 of the first joint 5, the wedge-shaped first insertion portion 60 and second insertion portion 61 of the second joint 6 are fitted into the first insertion receiving portion 14 and the second insertion receiving portion 15, respectively. Therefore, the vertical surface portion 30B of the canopy unit 1B and the vertical surface portion 30C of the canopy unit 1C do not shift out of position from their connected state.
[0053] [D-3] Connecting structure by the third joint As shown in Figures 12 to 14, the third joint 7 is a long element extending in the longitudinal direction of the inclined edge 400' of the inclined surface portion 40, with the first side in the shorter direction being the first half 7A and the second side being the second half 7B. A wedge-shaped first insertion portion 70 is formed in the first half 7A of the third joint 7, and a wedge-shaped second insertion portion 71 is formed in the second half 7B. The first insertion receiving portion 14 and the second insertion receiving portion 15 can be described by referring to the description of the first embodiment.
[0054] The third joint 7 according to this embodiment is obtained by bending a steel plate of a predetermined shape. As shown in Figure 22, the first insertion portion 70 is provided with an inclined first folded piece 72 formed by folding the first side portion of the plate material inward, and the second insertion portion 71 is provided with an inclined second folded piece 73 formed by folding the second side portion of the plate material inward, with the surface portion between the first folded piece 72 and the second folded piece 73 forming the base 74. The wedge-shaped first insertion portion 70 is formed from the first side portion of the base 74 and the first folded piece 72, and the wedge-shaped second insertion portion 71 is formed from the second side portion of the base 74 and the second folded piece 73. On the first side of the base 74 of the third joint 7, a covering piece 75 is bent and formed so as to closely cover the lower surface of the base 74. In this embodiment, the third joint 7 (and the other joints as well) has a dark surface and a light surface, preventing the back surface of the base 74 (which is whitish and conspicuous) from being exposed on the first side of the back surface of the third joint 7 (which is exposed when the canopy 1 is viewed from below). The third joint 7 may also be formed from a material other than a metal plate, such as resin.

[0056] The connection structure of the first surface (inclined surface 40C) of the first member (canopy unit 1C) and the second surface (inclined surface 40B) of the second member (canopy unit 1B) by the third joint 7 will be described. The inclined surface 40B of canopy unit 1B and the inclined surface 40C of canopy unit 1C are approximately perpendicular in plan view, and with the wedge-shaped first insertion part 70 of the third joint 7 fitted into the first insertion receiving part 14 of canopy unit 1C and the wedge-shaped second insertion part 71 fitted into the second insertion receiving part 15 of canopy unit 1B, the edges 400' of the inclined surface 40B of canopy unit 1B and the inclined surface 40C of canopy unit 1C are close together or in contact. In the illustrated embodiment, the edges 400' of the inclined surfaces 40B and 40C abut at approximately 45 degrees with respect to the direction in which the inclined surface 40B of the canopy unit 1B extends (visible direction X) and the direction in which the inclined surface 40C of the canopy unit 1C extends (depth direction Y).
[0057] As shown in Figures 12 and 14, the inclined edges 76 and 78, which are the first edges in the longitudinal direction of the first half 7A and the second half 7B of the third joint 7, form approximately 90 degrees in plan view.

As shown in Figures 13 and 14, in the canopy units 1B and 1C according to this embodiment, the first edge 401 of the inclined surface portion 40 is the corner between the inclined surface portion 40 and the front end hanging piece 41 (see Figure 3). The inclined edges 77 and 79, which are the second ends in the longitudinal direction of the first half 7A and the second half 7B of the third joint 7, form approximately a 90-degree angle in plan view. The inclined edge 77 extends along the second end edge 402 (extending in the depth direction Y) of the inclined surface portion 40 of the canopy component unit 1C, and the inclined edge 79 extends along the second end edge 402 (extending in the visibility direction X) of the inclined surface portion 40 of the canopy component unit 1B.
[0058] [E] Connecting structure of canopy component unit (third embodiment) [E-1] Overview As shown in Figures 1, 1B, and 15-18, an inner corner is formed by the canopy unit 1D and the canopy unit 1E. The connecting structure of the canopy units according to the third embodiment connects the two canopy units (canopy unit 1D and canopy unit 1E) that form the inner corner using the fourth joint 8 and the fifth joint 9.

To facilitate insertion of the second insertion portion 81 into the second insertion receiving portion, both ends of the second insertion portion 81 in the longitudinal direction are notched in an inclined manner. The fourth joint 8 may also be formed from a material other than a metal plate, for example, resin.

[0062] The wedge-shaped first insertion portion 80 of the fourth joint 8 is fitted into the first insertion receiving portion 14 formed on the back surface of the vertical surface portion 30D of the canopy unit 1D. The wedge-shaped second insertion portion 81 of the fourth joint 8 is fitted into the second insertion receiving portion 15 formed on the back surface of the vertical surface portion 30E of the canopy unit 1E. The edges 300' of the vertical surface portion 30D of the canopy unit 1D and the vertical surface portion 30E of the canopy unit 1E are close together or in contact, and in the illustrated configuration, the edges 300' are in contact with each other to form a butt joint. Similar to the first insertion portion 50 of the first joint 5, the wedge-shaped first insertion portion 80 and second insertion portion 81 of the fourth joint 8 are fitted into the first insertion receiving portion 14 and the second insertion receiving portion 15, respectively. Therefore, the vertical surface portion 30D of the canopy unit 1D and the vertical surface portion 30E of the canopy unit 1E do not shift out of position from their connected state.
