Description

[Technical Field]

[0001] This invention relates to a ladder fixing device that prevents a ladder from slipping when leaning it against a roof and climbing up and down. [Background technology]

[0002] In particular, when trying to lean a ladder against the roof of a house, the ladder may slip between the eaves and the roof, which is extremely dangerous. Therefore, as described in Patent Document 1, a ladder fixing device for fixing a ladder to the eaves of a roof has been proposed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2006-307475 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the ladder fixture in Patent Document 1 is attached to the ladder support pole using a U-shaped member, which means that it cannot be attached depending on the shape of the support pole. Also, because it is not configured to be firmly fixed to the support pole, there is a risk that it may shift up or down on the support pole after attachment.

[0005] The object of this invention is to provide a ladder fixture that can be securely fixed to ladder posts of various shapes. [Means for solving the problem]

[0006] The ladder fixing device of this invention comprises a fixed part which is fixed to one of the ladder posts using a fixing means, a clamping part which clamps the roof of a building or the like, and a connecting part which connects the fixed part and the clamping part, and the connecting part comprises a rotating plate which rotates relative to the fixed part, and an upright plate which stands up from the rotating plate and to which the clamping part is attached, and the clamping part rotates relative to the upright plate. The ladder fixing device can be securely fixed to the support via the fixing part, allowing the ladder to be climbed and descended safely.

[0007] The fixing part is characterized by having an anti-slip member arranged on the surface facing the support post. By providing the anti-slip member, the fixing part can be tightly attached to the support post, and the ladder fixing device can be fixed to the support post even more firmly. [Effects of the Invention]

[0008] The ladder fixture of this invention uses a fixing means to fix the fixing part to the ladder post, so it can be attached to posts of various shapes.In addition, it can be securely fixed, allowing for safe climbing and descending of the ladder. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is a perspective view of a ladder fixture. [Figure 2] Right side view of the ladder fixture. [Figure 3] View from the back of Figure 1. DETAILED DESCRIPTION OF THE INVENTION

[0010] 1 to 3, ladder fixture 1 comprises a fixing part 2 that is fixed to one of the support posts of a ladder (not shown) using a fixing means, a clamping part 3 that clamps the roof of a building, and a connecting part 4 that connects fixing part 2 and clamping part 3. A string or belt can be used as the fixing means, and fixing part 2 can be fixed by tying it to the support post.

[0011] (Fixed part 2) The fixing part 2 includes an anti-slip member 21 disposed on the surface facing the ladder support post, and a fixing part frame 22 positioned between the anti-slip member 21 and the connecting part 4. The anti-slip member 21 can be a rectangular urethane sponge extending in the longitudinal direction. Using the urethane sponge in this way allows the fixing part 2 to be tightly attached to the support post, preventing the ladder fixture 1 from slipping relative to the support post. The fixing part frame 22 has a U-shape extending in the longitudinal direction, and more specifically, includes flange surfaces 23 extending in the longitudinal direction and a web surface 24 positioned between the flange surfaces 23. The flange surface 23 includes a base end 23a that contacts the web surface 24 and a tip end 23b located opposite the base end 23a. The dimension from the base end 23a to the tip end 23b is smaller than the dimension of the anti-slip member 21. Therefore, the anti-slip member 21 extends from the tip end 23b. By adopting such a dimensional relationship, even if the anti-slip member 21 is deformed by fastening the ladder fixture 1 to the ladder support, the anti-slip member 21 can be brought into contact with the ladder without being hindered by the fixing part frame 22. The fixing part frame 22 can be made of metal, such as stainless steel. By using metal, the strength of the entire fixing part 2 can be maintained.

[0012] (Holding part 3) The clamping unit 3 includes a contact portion 31 that rotatably contacts the connecting portion 4, and a pair of clamping pieces 32 that stand up from the contact portion 31 and can clamp a roof or the like. At least one of the clamping pieces 32 is provided with an anti-slip member 33. Silicon, for example, can be used as the anti-slip member 33. The distance between the pair of clamping pieces 32 can be increased or decreased by fastening members 34. A bolt and nut can be used as the fastening member 34, and by tightening the nut, for example, a roof can be firmly clamped.

[0013] (Connection part 4) The connecting part 4 includes a rotating plate 41 that rotates relative to the fixed part 2, and an upright plate 42 that stands up from the rotating plate 41 and to which the clamping part 3 is attached. In this embodiment, an auxiliary plate 43 is provided facing the rotating plate 41, and the upright plate 42 connects the rotating plate 41 and auxiliary plate 43. The rotating plate 41 is attached to the web surface 24 of the fixed part frame 22 by a pin 44. A washer is provided between the rotating plate 41 and the web surface 24 to enable them to rotate. The rotating plate 41 can rotate in the direction indicated by arrow A.

[0014] The contact portion 31 of the clamping unit 3 is rotatably attached to the standing plate 42 via a fastening member 45. In this embodiment, the fastening member 45 includes a bolt 45a that passes through the standing plate 42 and the contact portion 31, a nut 45b at one end of the bolt 45a located on the clamping unit 3 side, and a nut 45c at the other end of the bolt 45a located on the connecting unit 4 side. Washers are provided between the nut 45b and the contact portion 31 of the clamping unit 3 and between the nut 45c and the standing plate 42 of the connecting unit 4. By loosening the fastening member 45, the contact portion 31 and the standing plate 42 can rotate, and by tightening the fastening member 45, the contact portion 31 and the standing plate 42 can be fixed so as not to rotate. When the fastening member 45 is loosened, the contact portion 31 and the standing plate 42 can rotate in the direction of arrow B.

[0015] With the above-described configuration, when a ladder is leaned against the roof of a building, for example, the ladder fixing device 1 is placed on the ladder's support pole located near the roof. More specifically, the fixing part 2 is positioned so that its longitudinal direction is approximately parallel to the support pole, with the anti-slip member 21 facing the support pole. The fixing part 2 and the support pole are fastened together with a fastening means such as a string or belt. At this time, the anti-slip member 21 deforms and adheres tightly to the support pole. The fastening member 45 of the connecting part 4 is loosened in advance so that it can rotate between the clamping part 3.

[0016] The clamping pieces 32 of the clamping section 3 clamp the edge of the roof, and the clamping pieces 32 are firmly fastened with fastening members 34 to prevent the clamp from coming loose. The clamping pieces 32 are provided with anti-slip members 33, so the roof can be securely clamped by the clamping pieces 32 and will not slip off. In addition, by using an elastic material such as silicon for the anti-slip members 33, scratches on the roof can be prevented. With the fastening members 45 loosened, the clamping unit 3 can rotate relative to the connecting unit 4, so it can flexibly rotate relative to the connecting unit 4 and clamp the roof in a stable position. Once the roof is clamped by the clamping unit 3, the fastening members 45 are pressed down to fix the positional relationship between the clamping unit 3 and the connecting unit 4.

[0017] According to this ladder fixture 1, the fixing part 2 is a roughly rectangular parallelepiped extending in the longitudinal direction and is fixed to the ladder support pole by a separate fixing means, so that it can be fixed to the support pole regardless of the type or size of the ladder. The fixing part 2, clamping part 3, and connecting part 4 are all rotatable, and since the fixing part 2 is fixed to the ladder, the clamping part 3 is fixed to the roof, and the clamping part 3 and connecting part 4 are fixed, the roof and ladder are firmly fixed via the ladder fixture 1. Therefore, the ladder will not slip off the roof, ensuring work safety.

[0018] The fixed part 2 and the connecting part 4 are rotatable via the pin 44, and are not fixed after rotation. Therefore, there is no need to tighten them each time, and they are easy to handle. However, they may also be fixed by tightening them after rotation using, for example, nuts and bolts. [Explanation of symbols]
