<4. Explanation of structure of coupling mechanism>
Next, the connection mechanism 4 to which the present invention for connecting the panel members 1 as described above is applied will be described.

  As shown in FIGS. 18, 19, and 20, the connection mechanism 4 includes a connection member 40 that connects the two panel members 1 and 1 linearly and vertically, and a connection that holds the connection member 40 in a vertically rotating state. And a reinforcing member 50.

  The connecting member 40 can be connected to the first main body portion 42 in which the first connecting concave portion 41 that can be connected to the connecting convex portion 25 of one panel member 1 and the connecting convex portion 25 of the other panel member 1 are formed. It has the 2nd main-body part 44 in which the 2nd connection recessed part 43 was formed, and the hinge part 45 which connects the 1st main-body part 42 and the 2nd main-body part 44 so that rotation is possible. In such a connecting member 40, for example, the first main body portion 42 and the second main body portion 44 are formed of a hard resin material, and the hinge portion 45 is formed of a soft resin material. Is formed.

  The first main body 42 is formed of a long member having a rectangular or square cross section that is longer in the length direction than the frame member 20. The first connecting recess 41 is a recess formed in a substantially U-shaped cross section from the one main surface 42a in the depth direction of the first main body 42 toward the other main surface 42b. As a result, the first main body portion 42 has a convex reinforcing portion 46 formed on the inner surface of the other main surface 42b of the first main body portion 42, and a pair of side surface portions 42c, 42c in the width direction of the first main body portion 42. Since the other main surface 42b is provided in a U-shaped cross section, the pair of side surface portions 42c and 42c are flexible in the width direction. Furthermore, on the inner surfaces of the tip portions of the pair of side surface portions 42c, 42c, an engaged portion 47 to be engaged with the engaging portion 25a of the connecting convex portion 25 of the panel member 1 accommodated in the first connecting concave portion 41. Is protruding.

  The second main body portion 44 has the same configuration as the first main body portion 42, and here, the same reference numerals are given and detailed description is omitted, but the other main surface 42 b of the first main body portion 42 is omitted. The other main surface 42 b is disposed so as to face each other, and is integrated with the other main surface 42 b of the first main body portion 42 via the hinge portion 45. Accordingly, as shown in FIG. 18, the connecting member 40 can linearly connect the two panel members 1 and 1 by arranging the first main body portion 42 and the second main body portion 44 linearly. At the same time, as shown in FIG. 20, the two panel members 1 and 1 can be connected vertically by arranging the first main body portion 42 and the second main body portion 44 vertically.

  A convex first fitting portion 48 a is formed on the outer surface of the other main surface 42 b of the first main body portion 42. The first fitting portion 48 a is formed from one end portion in the length direction of the first main body portion 42 to the other end portion. Furthermore, a concave second fitting portion 48 b that can be fitted to the first fitting portion 48 a is formed on the outer surface of the other main surface 42 b of the second main body portion 44. The second fitting portion 48b extends from one end portion to the other end portion in the length direction of the second main body portion 44 at a position corresponding to the first fitting portion 48a, similarly to the first fitting portion 48a. Is formed.

  Therefore, as shown in FIG. 18, when two panel members 1 and 1 are connected in a straight line, the first main body is fitted by fitting the first fitting portion 48a and the second fitting portion 48b. The linear state between the portion 42 and the second main body portion 44 can be firmly held. On the other hand, as shown in FIG. 20, when two panel members 1 and 1 are connected vertically, the first main body 42 and the second main body 44 are separated by a predetermined tensile force or more, It is necessary to cancel the fitting state between the first fitting portion 48a and the second fitting portion 48b. The first main body 42 may have a concave first fitting portion 48a, and the second main body may have a convex second fitting portion 48b.

  In addition, as shown in FIG. 19, both end portions in the length direction of the first main body portion 42 and the second main body portion 44 are notched at 45 °, the corner portions are chamfered, and the connecting inclined surface 49 is formed.

Thereby, the both ends of the length direction of the 1st main-body part 42 and the 2nd main-body part 44 are formed in the right triangle shape. Further, the connection inclined surface 49 is formed to be flush with the frame inclined surface 24 of each panel member 1 when the panel member 1 is attached to the first connection recess 41 and the second connection recess 43. .

<5. Explanation of the effect of the coupling mechanism>
As described above, the connection mechanism 4 includes the first main body portion 42 in which the first connection recess 41 that can be connected to the connection protrusion 25 of the one panel member 1 and the connection protrusion 25 of the other panel member 1. Since the second main body portion 44 formed with the second connection concave portion 43 that can be connected to the second main body portion 44 includes the connection member 40 that is rotatably connected via the hinge portion 45, the two panel members 1, 1 are They can be connected at an appropriate angle such as a straight line or vertical. Therefore, conventionally, when connecting in a straight line, a connecting member dedicated for linear connection is used, and in connecting vertically, a connecting member dedicated for L-shaped vertical connection is used. It can be used for both the case of connecting in a shape and the case of connecting vertically.

  The connecting member 40 of the connecting mechanism 4 has a first fitting portion 48 a formed on the outer surface of the other main surface 42 b of the first main body portion 42, and a first fitting portion 48 a on the outer surface of the other main surface 42 b of the second main body portion 44. Since the concave second fitting portion 48b that can be fitted to the one fitting portion 48a is formed, when the two panel members 1 and 1 are connected in a straight line, the first fitting portion 48a and the second fitting portion 48a are connected. By fitting the fitting portion 48b, the linear state between the first main body portion 42 and the second main body portion 44 can be firmly held.

  The connection mechanism 4 is disposed between the first main body portion 42 and the second main body portion 44 in a state in which the connection reinforcing member 50 is vertically rotated when the connection member 40 is used in the vertical rotation state. By doing so, the vertical rotation state of the first main body portion 42 and the second main body portion 44 can be reliably held.

  The connection mechanism 4 is not limited to the connection reinforcing member 50 maintaining the vertical rotation state of the first main body portion 42 and the second main body portion 44 of the connection member 40, and is not limited to 30 ° and 45 °. , A rotating state with a predetermined angle other than vertical, such as an acute angle of 60 °, an obtuse angle of 120 °, or the like, may be maintained. Furthermore, the connection reinforcing member 50 is not limited to being formed in a square cross section, but may be rectangular, and may be triangular or fan-shaped.

  Further, the connecting mechanism 4 may omit the connecting inclined surfaces 49 at both ends in the length direction of the first main body portion 42 and the second main body portion 44 of the connecting member 40 (see FIGS. 28 and 31). . Thereby, when the connection mechanisms 4 are juxtaposed in the length direction, the connection mechanisms 4 can be brought into close contact with each other.
