DETAILED DESCRIPTION OF THE INVENTION

[0009] A preferred embodiment of the mounting bracket for a temporary handrail skirting board of the present invention will be described below with reference to the drawings. First, the temporary handrail body 1 of this embodiment is a conventional one as shown in Figure 1, and consists of upper and lower handrail horizontal bars 11, which have sliding extensions on both ends so that their width can be changed as needed. Meanwhile, on both sides of the temporary handrail body 1, the lower parts of the vertical supports 12 are provided with vertical support bases 121, and fixed hollow floor poles 2 are provided at predetermined positions on the floor side, with the vertical support bases 121 inserted and fixed in place.

[0010] The feature of this invention is that the baseboard is stored at a position midway between the floor and the baseboard by means of a baseboard mounting bracket 4 that is slidably mounted on a vertical support 12, and the details of this will be explained with reference to Figures 5 to 11. 5, the baseboard mounting bracket 4 is attached to the vertical support 12 and consists of a pair of semicircular tightening pieces 41a, 41b, which are rotatably supported by a support shaft 42 consisting of a bolt and nut, and by turning the tightening grip 431 of the screw member 43 on the opposite side, the tightening pieces 41a, 41b on the opposite side are also tightened by the screw member 43, resulting in the baseboard being fixed in a predetermined position on the vertical support 12 to hold it in place between the floor and the baseboard. The tip of one of the tightening pieces 41b is bent into a C shape to prevent the other tightening piece 41a from falling off.

[0011] As shown in Figures 5 and 6, the baseboard retaining rod 5 of the baseboard 3 is arranged on the side of the tightening piece 41b so as to be able to rotate to an upper position (upper position in Figure 6) for storing it at the middle position of the vertical support 12, and to a lower position for storing it at the floor side position, and is fixed in each position. As shown in Figures 7 and 8, the baseboard stopper rod 5 has one end which is a straight rod 51 long enough to accommodate the baseboard, and the other end which is an L-shaped bent tip 52. As shown in Figure 5, the tip 52 has a protruding spring support part 521 which supports the spring 522 with the spring frame part 523, so that it is always pressed against the vertical support 12 and is supported so that it can rotate around the tip 52. The fixing means for this baseboard stopper rod 5 is a lock pin 53 provided near the L-shaped bend, with corresponding mating holes 54a, 54b provided on the outer surface 5231 of the spring frame portion 523. The baseboard stopper rod 5 is pulled out against the pressing force of the spring 522 into either the upper mating hole 54a or the lower mating hole 54b, releasing the mating and then mating it with the other mating hole 54a, b, thereby fixing the straight rod 51 of the baseboard stopper rod 5 upward or downward. Furthermore, by simply rotating the clamping grip 431 and loosening the clamping pieces 41a, b, the baseboard mounting bracket 4 not only allows the vertical support 12 to move up and down, but also allows the straight rod 51 to be inverted without having to remove the baseboard mounting bracket 4. The baseboard 5 can be installed on the floor side or the vertical support side. In this way, there is no need to remove the mounting bracket 4 for the baseboard from the vertical support 12, so it can be attached to the vertical support when dismantling at the site to prevent it from being lost.

[0012] As described above, normally, simply rotating the tightening grip portion 431 of the baseboard mounting bracket 4 loosens the tightening of the tightening pieces 41a, b, but they do not fall off. However, Figures 12 to 14 explain a mechanism that prevents the tightening pieces 41a, b from falling off the vertical support even when the tightening grip portion 431 is rotated and the tightening of the tightening pieces 41a, b is loosened. The anti-fall-off pin 62 that prevents the baseboard from falling off from the vertical support passes through gaps A and B in the plan view of Figure 5 and the vertical support 12 in Figure 12, and the passing pin 61 passes through the vertical support 12 as shown in Figure 13, but the head 621 and nut part 622 of the anti-fall-off pin 62 in Figure 14 are too thick to pass through gaps E and F, so they cannot pass through the vertical support 12 and the baseboard mounting bracket 4 will not fall off. Therefore, when dismantling on site, it can be attached to the vertical support 12 to prevent loss, and to completely dismantle the baseboard mounting bracket 4, the fall-off prevention pin 62 can be removed.

[0013] [Activation] The embodiment of the present invention has the above-mentioned configuration, and the overall operation will now be described. First, as shown in Figures 3 and 9, the lower ends of a pair of vertical supports 12 of the temporary handrail main body 1 are inserted into a pair of side fixed hollow holes 2 provided on the floor side, and the baseboards 3 are lined up on the floor side on these vertical supports 12. Once this is complete, the lock pin 53 on the straight rod 51 of the baseboard stopper rod 5 of the baseboard mounting bracket 4 is pulled out from the mating hole 54a, and then turned over so that it faces downward as shown in Figure 9, and the lock pin 53 is fitted into the mating hole 54b to secure it in place. In this case, if the baseboard 3 is thick or multiple baseboards 3 are stacked on top of each other, the position of the straight rod 51 of the baseboard stopper rod 5 relative to the vertical support 12 can be adjusted by rotating the fastening pieces 41a, 41b relative to the vertical support 12 as shown in Figure 11, as shown in Figure 10 (when there is one normal baseboard 3) and Figure 11 (when two or more baseboards 3 are stacked).As a result, the width between the vertical support 12 and the baseboard stopper rod 5 in Figure 11 can be adjusted by a distance X, and the baseboard 3 can be fastened to the vertical support 12 with the baseboard stopper rod 5.

[0014] In this way, the baseboard 3 is fixed to the floor side of the temporary handrail body 1, and normal work can be resumed. A case where the baseboard 3 is retracted from the floor side after the predetermined work is completed will be described. In this case, as shown in Figures 4 and 8, the baseboard mounting bracket 4 is moved to a position about halfway along the vertical support 12, the baseboard stop bar 5 of the baseboard mounting bracket 4 is raised, and the baseboard 3 is sandwiched and stored between this baseboard stop bar 5 and the vertical support 12. The reversal process is the reverse of that in Figure 9, and the lock pin 53 on the straight rod 51 of the baseboard stop bar 5 of the baseboard mounting bracket 4 is pulled out from the mating hole 54b, and then the baseboard is turned over so that it faces upward as shown in Figure 9, and the lock pin 53 is engaged with the mating hole 54a to secure it. Therefore, the baseboard stopper rod 5 can be adjusted to accommodate changes in the thickness of one baseboard 3 or the thickness of overlapping baseboards 3.

[0015] With the mounting bracket for temporary handrail baseboards of this embodiment, baseboards can be easily attached to the floor side of the temporary handrail, easily removed when pouring concrete, etc., and temporarily stored in the middle of the vertical axis of the temporary handrail, and then easily moved to the floor side when pouring work is completed, and because the baseboard stop rod 5 can rotate around the vertical support 12, it can be fixed to accommodate a variety of baseboards and baseboard thicknesses. Because there is no need to remove the baseboard mounting bracket 4 from the vertical support 12, the mounting bracket for temporary handrail baseboards can be attached to the vertical support 12 when dismantling the site to prevent them from being lost. In this way, by providing mounting brackets for temporary handrail baseboards, work efficiency at construction sites is improved. [Explanation of symbols]
