No. 21280 discloses an L-shaped ladder mounting seat for mounting a ladder split body (62) to a storage lid (61) as shown in FIG.
A configuration in which a long hole (64) is provided in a horizontal piece of (63) is disclosed. Thereby, the ladder split body (62) attached to the storage lid (61)
Can be moved up and down relative to the storage lid (61) by the length of the long hole (64) of the ladder mounting seat (63) to adjust it according to the height of the ceiling. The step board of the ladder split body (62) is held horizontally. However, even when the ladder split body (62) is attached to the bottom of the storage lid (61), the heavy storage lid (61) is held in the closed state so that opening and closing work can be performed with a small force. Therefore, it was necessary to use a lifting spring having a high tension. For this reason, a large force is required for the work of hanging the lifting spring. Also, when the ladder split body (62) is attached to the top, the lower end of the expanded ladder split body (62) floats because of the use of a strong tension spring. The opening and closing of the storage lid (61) is too fast.

(67) with the stopper (69), adjust the inclination angle of the suspension link (68), adjust the opening angle of the storage lid (61), adapt to the difference in ceiling height There is an example to do. In this case, the storage lid
Since the position where the ladder split body (62) is attached to the (61) is fixed, there is no need to increase the tension of the lifting spring (70) more than necessary, and the work of hanging the lifting spring (70) is easy. However, because the opening angle of the storage lid (61) is different, the contact angle of the extended ladder split body (62) is also different, and as a result, the tread of the ladder split body (62) tends to be upward or downward, The horizontal state cannot be maintained.
