More specifically, the distance between the first distal edge 51 a and the second distal edge 52 a can be changed by the pressing and fixing means 7 attached to the first plate-like portion 51 and the second plate-like portion 52. As the pressing and fixing means 7, a bolt 71 and a nut 72 can be used. By tightening the bolt 71 and the nut 72 of the pressing and fixing means 7, it is possible to strengthen the holding of the shell by the first distal edge 51a and the second distal edge 52a.

  The connecting member 5 is manufactured from a single metal plate 6. As shown in FIG. 5, the metal plate 6 is substantially rectangular and is defined by a first side edge 61, a second side edge 62, and both end edges 65. The first side edge 61 and the second side edge 62 correspond to the first distal edge 51a and the second distal edge 52a of the connecting member 5, respectively. The metal plate 6 is located between the first side edge 61 and the second side edge 62 and has a central folding line 63 extending from one end edge 65 to the other end edge 65. The metal plate 6 can be bent through a central folding line 63 so that the left side of the drawing with respect to the central folding line 63 can be the first plate-like portion 51 and the right side of the drawing can be the second plate-like portion 52. The center folding line 63 corresponds to the first proximal edge 51b and the second proximal edge 52b.

  The dimension from the central folding line 63 to the first side edge 61 corresponding to the first distal edge 51a is slightly smaller than the dimension from the central folding line 63 to the second side edge 62 corresponding to the second distal edge 52a. large. In this embodiment, the dimension from the central folding line 63 to the first side edge 61 is about 57.3 mm, and the dimension from the central folding line 63 to the second side edge 62 is about 57.0 mm. The length dimension of the first distal edge 51a and the second distal edge 52a is about 1 m.

  On the central folding line 63, a slit 64 extending along the central folding line 63 is provided. A plurality of slits 64 are arranged apart from each other. By providing the slit 64, the metal plate 6 can be easily bent along the central folding line 63.

  An insertion port 55 into which the attachment portion 44 of the second support member 4 can be inserted is provided at a portion corresponding to the first plate-like portion 51 of the metal plate 6. The insertion port 55 and the attachment portion 44 can be fixed to each other by welding or the like. The insertion ports 55 are provided at three locations near both end edges 65 and approximately the center of both end edges 65. A plurality of oval bolt holes 73 into which the bolts 71 are inserted are further formed in a portion corresponding to the first plate-like portion 51 of the metal plate 6. The bolt holes 73 are provided on both sides of the insertion port 55 and substantially at the center between the insertion ports 55. A square head bolt is used as the bolt 71, and a square hole 74 in which a square head of the bolt can be fitted at a position corresponding to the bolt hole 73 is formed in a portion corresponding to the second plate-like portion 52 of the metal plate 6.

Further, the bending angle of the first distal edge 51a is larger than that of the second distal edge 52a. By using different bending angles in this manner, it is possible to make it difficult for the clamp 12 to come off. Similarly, by making the dimension from the central folding line 63 to the first distal edge 51a or the second distal edge 52a different, it is possible to make it difficult to remove the connecting member 5 from the clamped shell 12.

  According to the lifeline engaging device 1 having such a configuration, the lifeline can be attached to the rod member 2. By attaching a lifeline to the bar member 2, an operator on the roof can move in the axial direction 21 along the main building 11. It is also possible to move to the opposite roof across the main wing 11 without removing the lifeline. Since the lifeline engaging device 1 is attached to the main ridge 11 located at the uppermost part of the roof 10, for example, it does not interfere with work such as snow removal on the roof. In addition, the lifeline extending from the main building 11 is unlikely to obstruct the work.

  Since the connecting members 5 are provided on both sides of the main building 11, for example, even when a load is generated in a direction away from one of them, the second support member 4 fixed to the connecting member 5, The force is distributed to the second support member 4 and the connecting member 5 on the opposite side of the main building 11 via the first support member 3. Therefore, it is difficult for the connecting member 5 to come off, and the lifeline engaging device 1 as a whole can be prevented from falling off the roof 10. Further, since the connecting member 5 extends in the axial direction 21, the force in the direction of further detachment is dispersed.

  As described above, since the lifeline engaging device 1 can be installed without making a hole in the roof 10, the roof 10 is not damaged. Moreover, the lifeline engaging apparatus 1 can be firmly fixed to the roof 10 by installing using the connecting member 5.

  In this embodiment, as each member constituting the lifeline engaging device 1, a normal material used in the field of this technology can be used in addition to a metal such as iron or stainless steel. Moreover, the dimension of each member can be suitably changed according to the intensity | strength, magnitude | size, etc. of a member. The first support member 3 and the second support member 4 are provided at least in the vicinity of both ends of the rod member 2, and the number thereof is not limited. The first support member 3 and the second support member 4 are separate members, but they may be the same member. In this embodiment, the first support member 3 and the second support member 4 are separate members, and these can be moved relative to each other, so that the dimensions from the bar member 2 to the connecting member 5 can be adjusted. Even if the shape and size of the roof are different, the lifeline engaging device 1 can be attached.
