The top plate that connects the top plate and the leg element by the stepped pins protruding from the other front part and the rear part, and inserts the curtain plate between the leg elements to prohibit the left and right movement of the leg element with respect to the top plate. A connecting structure of plates and leg elements is considered. Specifically, the front connecting hole has a structure in which the passage hole and the locking hole are continuous in the front-rear direction, and the rear connecting hole has a structure in which the passing hole and the locking hole are continuous in the left and right, and the pin has the structure of the locking hole. It has a shaft portion having a diameter smaller than the width and a head portion capable of passing through the passage hole and having a diameter larger than the locking hole.

By sliding, the front pin is moved from the passage hole to the locking hole and locked. Immediately before the end of this operation, the rear pin reaches the vicinity of the passage hole of the rear connecting hole, so that the rear pin is inserted so as to be pushed into the passage hole. Further, by rotating the leg element outward with respect to the top plate with the front pin as an axis, the rear pin is moved from the passage hole to the locking hole side and locked in the locking hole. Finally, by connecting the curtain plate between the leg elements, the lateral movement of the leg elements with respect to the top plate is prohibited, and the connection between the top plate and the leg elements is maintained.

結にガタつきが発生するという不具合がある。However, even with such a structure, it is difficult to sufficiently eliminate the complexity of the work. That is, when the front pin is inserted into the front connecting hole, the rear pin cannot be inserted into the rear connecting hole at the same time, so that the top plate and the leg element cannot contact as a whole,
The leg elements have to be inclined with respect to the top plate, with the gap increasing toward the rear. Then, with the front pin tilted with respect to the vertical direction, the front pin is slid in the connecting hole, and the rear pin is pushed into the rear connecting hole only when the rear pin is positioned on the rear connecting hole. Since it has to be inserted into the, the resistance is large and the complexity of the work cannot be eliminated. Further, in order to lock the front pin in the front locking groove in the inclined state as described above, the stepped pin is provided with the connecting hole in the dimension of the shaft portion from the base end to the head. It must be much longer than the wall thickness. Therefore, after the rear pin is inserted into the rear connecting hole and the inclination of the leg element with respect to the top plate disappears, a so-called play occurs between the head and the inner surface of the connecting hole due to the long shaft portion of the pin. There is a problem that rattling occurs in the connection between the top plate and the leg elements.

結状態が維持される。In this mounting structure, when connecting the top plate and the leg element, the leg element is first attached to the top plate while inserting the front pin into the passage hole of the front connecting hole. At this time, the rear pin is arranged at a position facing the front surface of the passage hole of the rear connecting hole. Then, the leg element is moved relative to the top plate so that the front pin moves in the front connecting hole from the passage hole toward the locking groove. As a result, the front pin enters the front locking groove and is locked, and at the same time, the rear pin enters the rear passage hole through the front end of the rear passage hole. At this time, even if the rear pin slightly shifts and comes into contact with the front surface in the vicinity of the rear passage hole, the front end of the rear passage hole into which the rear pin should be inserted can be easily found by swinging the leg element to the left or right. .
Further, the rear portion of the leg element is rotated with respect to the top plate in the direction in which the rear pin moves in the rear connecting hole from the passage hole toward the locking groove. That is, the leg element is rotated outward. As a result, the rear pin is also locked in the locking groove of the rear connecting hole. In this position, the connection between the rear pin and the rear connecting hole and the connection between the front pin and the front connecting hole are prohibited from being released unless the leg element is rotated in the opposite direction again. Finally, if the curtain plate is inserted between the leg elements, the leg elements cannot move inward, and the top plate and the leg elements are connected to each other at the front and rear parts, and the connected state is maintained.

る。Thus, according to the present invention, since the rear pin is located at the front end of the rear passage hole when the front pin is inserted into the front passage hole, the leg element is brought into contact with the top plate at this point. Can be contacted. Therefore, the subsequent work becomes extremely easy. Further, when the front pin is moved from the front passage hole to the front locking groove and locked, the rear pin simultaneously enters the rear passage hole through the front end of the rear passage hole,
No special work is required to insert the rear pin into the rear passage hole. Furthermore, since there is no inclination with respect to the vertical direction when the front pin is locked in the front locking groove, the pin axial dimension should be as close as possible to the wall thickness dimension of the plate provided with the connecting hole. It is possible to eliminate the occurrence of play between the head of the pin and the inner surface of the connecting hole as much as possible, and to strengthen the connection between the top plate and the leg element.

きる。As described above, in this embodiment, when the front pin 21 is inserted into the front passage hole 13, the rear pin 22 is located at the front end 14c of the rear passage hole 14a. It can be mounted on the top plate 1. Therefore, the subsequent work becomes remarkably easy and the labor is reduced. Further, when the front pin 21 is moved from the front passage hole 13a to the front locking groove 13b and locked,
At the same time, the rear pin 22 enters the rear passage hole 14a through the front end 14c of the rear passage hole 14a, so that no special work is required to insert the rear pin 22 into the rear passage hole 14a. The positional displacement with respect to the rear passage hole 14a can be easily corrected. Further, when the front pin 21 is locked in the front locking groove 13b, since the pin 21 is not inclined with respect to the locking groove 13b, the dimension of the shaft portion 211 of the pin 21 can be adjusted as described above. As far as it can be obtained, it can be made as close as possible to the wall thickness dimension of the front frame member 13. Therefore, the occurrence of play between the head 212 of the pin 21 and the inner surface of the connecting hole 13 is eliminated as much as possible,
The top plate 1 and the legs 2 can be connected more firmly.
