Since the movable end frame 8 and the fixed end frame 9 have exactly the same shape and only one type of end frame needs to be manufactured, the cost can be reduced.

  Next, a description will be given of the lock means 7 for locking the movable end frame 8 configured as described above in a vertical posture orthogonal to the longitudinal direction of the skirting board main body 5. The lock means 7 is shown in FIGS. Thus, along the tilting direction of the end frame 8 along the tilting direction of the end frame 8 (along the curve centering on the pivot axis 12), the lower end of the U-shaped frame mounting frame 14 attached to the movable end frame 8 And a large-diameter round hole 22 (see FIGS. 5 and 6) formed in communication with the front end portion of the long hole 17 and a base plate body 5 through-supported so as to be movable in the axial direction. A shaft member 18 having a first shaft portion 18a having a small diameter that is slidably fitted in the long hole 17, a second shaft portion 18b having a large diameter that is fitted in the round hole 22, and an operating handle 23; The shaft member 18 is normally fitted into the round hole 22 by the second shaft portion 18b as shown in FIG. And a coil spring 24 for energizing the coil.

  As shown in FIGS. 5B and 6B, the coil spring 24 has a small diameter shaft of the shaft member 18 between the flange 5d of the baseboard body 5 and the rear end surface of the second shaft portion 18b. The shaft member 18 is fitted into the portion 18c, and the tip of the shaft member 18 forms a screw shaft portion 18d. The nut 25 is screwed onto the screw shaft portion 18d. The shaft portion 18 b is held at a position where the shaft portion 18 b is fitted into the round hole 22 at the front end portion of the long hole 17, that is, at the lock position.

  5A to 5C show a state in which the lock means 7 is in the lock position and the movable end frame 8 is locked in a vertical posture orthogonal to the longitudinal direction of the baseboard body 5. FIG. In other words, in this locked position, the shaft member 18 is held by the coil spring 24 at a position where the second shaft portion 18 b having a diameter larger than the hole diameter of the long hole 17 is fitted in the round hole 22 at the front end portion of the long hole 17. Therefore, as can be seen from FIG. 5C, even if a force that tilts the movable end frame 8 in the backward direction is applied to the lower end of the movable end frame 8 in this state, the movable end frame 8 Is prevented from tilting and can maintain a vertical posture. Therefore, as shown in FIG. 5 (a), the locking recess 10a of the movable end frame 8 is locked to the cross member 3 of the scaffolding frame 2. In this state, even if a large upward force is applied to the movable end frame 8 side, the movable end frame 8 does not tilt in the backward direction against the urging force of the leaf spring 13. There is no risk of falling out of the door and safety is ensured.

  FIGS. 6A to 6C show a state in which the lock means 7 is in the unlocked position. That is, in order to release the lock by the locking means 7, the handle 23 for the shaft member 18 is grasped and the shaft member 18 is moved in the axial direction against the urging force of the coil spring 24 from the state shown in FIG. When pushed in, the large-diameter second shaft portion 18b is detached from the round hole 22, and the small-diameter first shaft portion 18a can be fitted into the long hole 17. In this state, the movable end frame 8 When a force that tilts the movable end portion frame 8 in the backward direction is applied to the lower end portion of the first shaft portion 18 as shown in FIG. The movable end frame 8 can be tilted in the backward direction. When the first shaft portion 18 a is fitted in the long hole 17, the end surface of the large-diameter second shaft portion 18 b is pressed against the inner wall portion 14 a of the mounting frame 14 by the biasing force of the coil spring 24. The shaft member 18 does not return to the lock position even if the hand is released from the operation handle 23.

  In order to attach the scaffold board base plate 4 configured as described above to the scaffold board 1, the base board body 5 is lifted onto the side edge portion of the scaffold board 1, and the fixed end frame 9 of the fixed end frame 9 is first moved.

  When the base plate 4 is attached, the locking recess 11a of the fixed end frame 9 is first locked to the cross member 3, and then the locking recess 10a on the movable end frame 8 side is locked to the cross member 3. Then, the locking recess 11a on the fixed end frame 9 side is also elastically locked to the cross member 3 by the biasing force of the leaf spring 13, so that the locking recess 10a on the movable end frame 8 side and the fixed end are fixed. The locking recesses 11a on the side of the part frame 9 are stretched in opposite directions, so that the skirting board main body 5 can be firmly fixed on the side edge of the scaffold plate 1 in an upright posture.

  7A to 7C show a state where the locking recess 11a of the fixed end frame 9 is locked to one side member 3, and then the locking recess 10a of the movable end frame 8 is changed to the other side member 3. This shows the work procedure for engaging the skirting board 4 with the lock means 7 unlocked, as shown in (a), lowering the movable end frame 8 side of the skirting board 4 from above the cross member 3. Then, the locking recess 10a of the locking piece 10 of the movable end frame 8 is brought into contact with the circumferential surface of the cross member 3 slightly in front of the center, and from this state, the movable end frame 8 of the base plate 4 is brought into contact. When the side is pushed down, the lower end portion of the locking piece 10 slides down from the peripheral surface of the cross member 3, and a force in a direction retreating from the cross member 3 acts on the locking piece 10. Counteracts the biasing force of the leaf spring 13 and tilts backward about the pivot 12 as shown in (b), and finally the locking recess 10a of the locking piece 10 is shown in (c). State In sealed crosspiece 3 elastically against and is engaged, the skirting body 5 can be fixed to the upright posture on the side edge portions of the scaffolding board 1.

  In short, when the movable end frame 8 side of the skirting board 4 is pushed down from the state shown in (a), the movable end frame 8 moves backward against the urging force of the leaf spring 13 by its own weight and its pushing down force. By tilting in the direction, the locking recess 10a is instantaneously locked to the cross member 3, and the state shown in FIG. In the state shown in (c), the large-diameter second shaft portion 18b of the shaft member 18 constituting the locking means 7 is fitted into the round hole 22 at the front end portion of the long hole 17, so that the movable end portion frame is left as it is. 8 is locked in a vertical position.

  In this embodiment, the pair of locking recesses 10 a, 10 a, 11 a, 11 a of the end frames 8, 9 are locked on both sides with the hook F of the scaffold plate 1 locked to the cross member 3. However, the hook F of the scaffolding plate 1 may be engaged with the cross member 3 on one side of the hook F without pinching the hook F. However, if the structure is such that the hook F of the scaffolding plate 1 is sandwiched and held on both sides as in the embodiment, the structure of the lower ends of the end frames 8 and 9 can be made compact, and a pair of locking recesses 10a, 10a, 11a, 11a can be stably locked with respect to the cross member 3, and when the baseboard 4 is continuously attached side by side as shown in FIGS. 4 (b) and 4 (c), the scaffold plate 1 The hook F and the locking recesses 10a, 10a, 11a, 11a do not interfere with each other, and can be locked accurately.
