る。[Detailed explanation of the idea] Ladders for construction work are attached to power transmission line towers, etc., but in order to prevent people from climbing up and down them at all times,
A lifting prevention plate is installed. The present invention relates to a cover for the mounting bolt of the lifting prevention plate.

るカバーであつて、子供等のいたずらによる事故
を完全に防止しようとするものである。 This type of elevation prevention plate is attached to both the front and back sides of the ladder so as to cover the front and back sides, and the two are tightened with bolts. This usually covers the bottom of the ladder, so it generally cannot be climbed or lowered. However, since the tip of the bolt passes through the nut and protrudes from the lifting prevention plate on the back side for a relatively long time, children may climb up the ladder by putting their feet on it.
The present invention is a cover that covers the tip of the bolt protruding from the back side of the lifting prevention plate so that the user cannot put their feet on it, and is intended to completely prevent accidents caused by mischief by children and the like.
以下図についてその一実施例を説明する。図示

に噛合するピンラツク２が取り付けられている。 An example will be described below with reference to the drawings. The illustrated ladder 1 also serves as a rail for an automatic elevator (not shown), and a pin rack 2 that meshes with the pinion of the elevator is attached to the center.

考案に係るボルトカバー６がこれを覆うように取
り付けられる。 At the bottom of the ladder 1, as shown in FIGS. 2 and 3, there are three lifting prevention plates 3a covering the front and back.
3b is attached. Front and back lifting prevention plates 3a,
3b is tightened with a plurality of bolts 4 and nuts 5 at appropriate intervals on both sides. The tip of the bolt 4 protrudes from the outer surface of the nut 5, and a bolt cover 6 according to the present invention is attached to cover it.

は、突出したボルト４の先端と同等以上の高さを
有するものとする。 The bolt cover 6 has a seat 6a at one end in which a mounting bolt insertion hole is bored. A nut 5 can be screwed onto the tip of the mounting bolt 4 protruding from the seat. Adjacent to the catch seat 6a, a slanted portion 6b is formed that rises substantially perpendicularly therefrom and slopes downwardly toward the opposite side of the catch seat. The top of the oblique portion 6b has a height equal to or higher than the tip of the protruding bolt 4.

にはナツト５が螺合される。 This bolt cover 6 has a lifting prevention plate 3b on the back side.
The tip of the bolt 4 protruding from the seat 6a is inserted into the bolt insertion hole of the seat 6a, and the bolt 4 is attached so that the oblique portion 6b faces outward and is positioned above the bolt 4. A nut 5 is screwed into the tip of the bolt protruding from the seat 6a.
本考案は以上のように構成される。従つて、昇

ができる。 The present invention is constructed as described above. Therefore, since a slope is formed adjacent to the upper side of the tip of the bolt 4 protruding from the lifting prevention plate 3b, it is impossible to put your foot on the tip of the bolt, and the foothold is completely lost, making it impossible to climb. . This can prevent accidents caused by children and others climbing up the steel tower.
