いる。2. Description of the Related Art Conventionally, a ladder has been used for fire fighting in a building fire, and as such a ladder, there is a retractable ladder as shown in FIGS. 5A and 5B. In the figure, reference numeral 101 is a first ladder, and the first ladder 10
Reference numeral 1 is composed of four extended main rods 102, and a horizontal rod 103 and a support rod 104 which are installed between the main rods 102. The second ladder 105 can be stored in the first ladder 101, and the interval between the main rods 106 of the second ladder 105 is only narrower than the interval between the main rods 102 of the first ladder 101.
It has the same horizontal rod 107 and branch rod 108. A hook metal 109 is used to extend the second ladder 105 housed from the inside of the first ladder 101 and hold the second ladder 105 in a long state.

11 and a leaf spring 11 for constantly urging the tip portion of the support claw member 111 in a direction in which it projects from the inside of the hook body 110.
2 and rotatably attached to the hook body 110, and when rotated, the tip portion of the support claw member 111 is attached to the hook body 1.
It is composed of a pushing member 112 for pushing the pushing member 10 and a compression spring 113 for biasing the pushing member 112 in the rotation direction.

すると、第2梯子105は第1梯子101に支持され、
この伸縮自在梯子は伸した状態に保持される。When the wire 114 is pulled through the pulleys 115 and 116, the stored second ladder 105 is moved upward, and the support rod 10 located at the lower end side of the second ladder 105.
8 is engaged with the support claw member 111 of the hook metal 109. Then, the second ladder 105 is supported by the first ladder 101,
This retractable ladder is held in the stretched state.

伸縮自在梯子は収縮される。Since it is necessary to retract the retractable ladder after using it, when the wire 114 is pulled a little again, the support rod 108 of the second ladder 105 causes the pushing member 112 to resist the urging force of the compression spring 113. And press it clockwise. If the wire 114 is returned after the support rod 108 has passed over the pushing member 112, the second ladder 105 will move downward in the future, and as shown in FIG. 7, the support rod 108 will catch on the pushing member 112 and reverse it. When the pushing member 112 is rotated in the clockwise direction, the pushing member 112 comes into contact with the tip end portion of the supporting claw member 111, and the supporting claw member 111 is pushed into the hanging metal body 110. Support claw member 1
When 11 is pushed in, the support rod 108 can pass downward, the second ladder 105 is stored in the first ladder 101,
The retractable ladder is retracted.

収縮させることができなくなるという問題点があった。However, in such a conventional metal fitting of the retractable ladder, the compression spring 11 is used to urge the pushing member 112 in the counterclockwise direction.
3 is used, once the wire 114 is pulled to contract the retractable ladder, the pushing member 112 is rotated clockwise by the support rod 108 as shown in FIG. It often happens that the end of 110 is caught. When the compression spring 113 is caught on the end of the hanging metal member 110 in this way, the pushing member 112 cannot rotate clockwise thereafter, and as a result, as shown in FIG. It becomes impossible to push the support claw member 111 into the hanging bracket main body 110 via 112. As a result, there is a problem in that the stretchable ladder in the stretched state cannot be contracted.

A hanging metal fitting that is provided on the one ladder of the expandable and contractible ladder including at least two ladders and that engages with the other ladder and supports the other ladder, and is rotatably attached to the hanging metal body. A support claw member that engages with the support rod, a first spring member that biases the support claw member in the engaging direction, and a support claw member that is rotatably attached to the hanging metal body to rotate the support claw member. A pushing member for pushing into the main body of the hanging metal,
A second spring member that biases the pushing member in the rotation direction is provided, and the first spring member and the second spring member are integrally formed by a single plate spring.

内に収納される。When the other ladder moves upward, the support bar pushes the pushing member against the biasing force of the leaf spring. At this time, since the leaf spring biases the pushing member, the leaf spring does not catch on the hook body. Therefore, the support rod can pass over the pushing member. When the other ladder is moved downward, the support bar pushes the supporting claw member through the pushing member, so that the other ladder is stored in the one ladder.

1によってこの伸長状態が保持されて使用可能となる。To extend and use the retractable ladder, pull the rope 19 to move the second and third ladders 8 and 15 upward, and the support rod 18 of the third ladder 15 is the second ladder 8. Is engaged with the hook metal fittings 21 provided on the second ladder 8 and the supporting rod 1 of the second ladder 8.
1 engages with a metal fitting 21 provided on the first ladder 1. That is, as shown in FIG. 2, when the support rod 11 moves upward, the support rod 11 pushes the support claw member 23 of the hook 21 into the hook main body 22 against the urging force of the plate spring 24. It passes over the support claw member 23. When the support rod 11 passes, the supporting claw member 23 projects from the opening 22 a of the hanging metal body 22 by the urging force of the leaf spring 24. The support rod 11 engages with the recess 23a of the projecting support claw member 23, and the second ladder 8 is supported by the first ladder 1 via the hook 21. In this way, the retractable ladder is extended upward and the hook 2
By 1, the extended state is held and can be used.

The third ladders 8 and 15 move upward. That is, as shown in FIG. 3, when the support rod 11 of the second ladder 8 moves upward, it abuts against the pushing member 25 and rotates it clockwise, and resists the biasing force of the leaf spring 24 to push this pushing member 25. The member 23 is pushed rightward from the left end of the hook 22. At this time, since the leaf spring 24 biases the pushing member 25, the leaf spring 24 is moved to the right side in FIG. 3 even if it is pushed by the support rod 11, and the leaf spring 24 is moved to the end 22c of the opening 22a. It doesn't get caught. Even if it is caught, the pushing member 25
Can be pushed rightward from the left end. Therefore, the support rod 11 can pass over the pushing member 25.

As shown in FIG. 5, the pushing member 25 is contacted with and rotated in the counterclockwise direction, the pushing member 25 is brought into contact with the projecting end portion of the supporting claw member 23, and the supporting claw member 23 is pushed into the hook body 22. . At this time, since the pushing member 25 and the supporting claw member 23 are made of 66 nylon having slipperiness, the pushing member 25
The support claw member 23 can be pushed in smoothly.
In this way, the second and third ladders 8 and 15 are attached to the hooks 21
The retractable ladder is retracted and stored in the first ladder 1, and the retractable ladder contracts.

る。As described above, according to the present invention, since the first spring member and the second spring member are composed of one leaf spring, the pushing member is pushed by the supporting rod, and this supporting rod is It is possible to pass over the pushing member, and thus the supporting claw member can be pushed through this pushing member. Therefore, the other ladder is disengaged from the engagement of the hooks and accommodated in the one ladder, and the telescopic ladder can be contracted. Further, since it is composed of one leaf spring, the number of parts can be reduced and the cost can be reduced.
