A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 4. these The ladder 1 shown in the figure is divided into a plurality of tiers, namely an upper tier 2, a middle tier 3 and a lower tier 4. each stage, and a support foot 5 that is fitted into the tip of the upper stage 2 and can move forward and backward as necessary. Become. When not in use, each of the above tiers is stacked on top of each other, and the emergency exit It is housed in a housing space 8 bored in the wall 7 on either the left or right side of the housing 6 . In addition, the collection As a structure that simply locks to the wall 7 and evacuates from the emergency exit 6 without forming the storage space 8. Good too.

[0011] The lid plate 9 carries the ladders 1 in a stacked state as shown by the two-dot chain line, and fills the accommodation space. 8 and a hinge 9a (see FIGS. 3 and 4). Also, this The cover plate 9 has a guide groove 9b for slidably connecting it to the lower stage 4. In this embodiment, the ladder 1 and the wall 7 are rotatable and slidable. This means that they are connected. Furthermore, the lid plate 9 has a hinge 9c in the middle as shown in FIG. It can be bent along the stepped floor 10 formed in front of the accommodation space 8. It has become.

0012 Reference numeral 9d denotes a handle that can be used to open the cover plate 9 when the ladder 1 is in the stored state shown by the solid line in FIG. This is for locking with a known structure. Reference numeral 11 in FIG. 1 indicates the handrail of ladder 1. Attach the mounting brackets provided to the connecting frame 3a and step portion 3b of the middle stage 3. When stored, it is removed and locked to the lid plate 9 as shown in FIG. 3.

[0013] As shown in FIG. 1, the lower stage 4 is divided into two parts, a footboard part 4a and a slope 4b. Both are rotatably coupled at a hinge coupling portion 4c. Also, on the back side of the lower row 4 is the above-mentioned A plurality of rollers 4d rolling in the guide groove 9b are arranged on the front side, and the next middle stage 3 and the rollers 4d are arranged on the front side. A guide groove 4e is provided for coupling in a freely riding manner.

[0014] The middle stage 3 consists of a connecting frame 3a and a step part 3b, both of which are connected by a hinge. They are rotatably connected at part 3c. On the back side of the middle stage 3, there is a guide groove 4e. A plurality of rollers 3d are provided for moving, and a guide groove 3e and a step are provided on the front side. A tap 3f is provided.

[0015] The upper tier 2 consists of a connecting frame 2a on the middle tier side and a step part 2b, and a step part 2b on the front side. There is also a roller 2d on the back side that rolls within the guide groove 3e of the middle stage 3. . The connecting frame 2a has a middle section so that the upper section 2 and the middle section 3 can be connected while maintaining a straight line. The structure is such that the stage 3 is held from both sides over a certain length.

[0016] The support legs 5 housed on both sides of the tip of the upper tier 2 are in the position shown in the solid line when in use. It can be slid to the position housed in the housing space 8 shown by the two-dot chain line. When in use, it is locked by a mechanism not shown. Such support foot 5 is adopted. By using this, the length of the ladder 1 can be substantially extended.

[0017] In the above configuration, the guide grooves 9b, 4e, 3e and the rollers 4d, 3d, 2d A sliding mechanism is constructed by the combination of these, and the stopping device of these sliding mechanisms is For example, a stock provided on one side, such as between the lower stage 4 and the lid plate 9 shown in FIG. This is done by the contact between the pad 4f and a stopper 9d provided on the other side. Upper tier 2 and support The stopping device for the work leg 5 is the same, but in this case, the stopper inside the tip of the upper stage 2 In this case, a cushioning material 2e is provided to reduce the impact when the support foot 5 protrudes to the operating state. Lageru.

[0018] The step 2c in the upper stage 2 can be rotated in the direction of the arrow mark (clockwise) around the right end of Fig. 1. is biased in the opposite (counterclockwise) direction by a spring means (not shown), and is applied to the stopper 2f. It abuts and functions as a step. When accommodating ladder 1, step 2 must be completed in advance. By rotating c in the direction of the arrow mark against the spring, interference with middle stage 3 can be avoided. can be done.

[0019] A damper 12 is provided between the connecting frame 3a of the middle stage 3 and the connecting frame 2a of the upper stage 2. ing. This is because when extending Ladder 1, the sliding speed is affected by gravity. This is to control the speed so that it does not become too fast.

[0020] As shown in FIGS. 3 and 4, a buffer lowering device 13 is provided in the accommodation space 8, It is connected to the side of the ladder 1 opposite to the hinge by a rope 13a. by this, Rotate from the accommodated state shown by the solid line in Figure 4 to the position facing the emergency exit 6 shown by the two-dot chain line. When opening the door, open it slowly to avoid sudden rotation that would cause it to fall over.

[0021] Next, the procedure for using it will be explained. Is the emergency ladder stowed? First, remove the handrail 11, then rotate the left and right handles 9d ( Figure 5).

[0022] This opens the cover plate 9, and the stacked ladders 1 come out (Fig. 6 ). At this time, adjust the buffer lowering device 13 (Figure 4) so that the opening speed is appropriate. I'll keep it that way.

[0023] Once the ladder 1 is placed on the floor 10, move the end of the rope 13a in the direction of the arrow. (Figure 7).

[0024] Apply force to the entire ladder 1 in the direction of the arrow mark and push it to the hinge 9c of the cover plate 9. (Figure 8).

[0025] When you push the lower tier 4 forward with your foot (Figure 9), the force of falling is added to the force of being pushed out. Therefore, the lower tier 4, the middle tier 3, the upper tier 2, and the support foot 5 slide in sequence and jump. Then, the tip of the support foot 5 reaches the track bed 15 below the rail 14 and is fixed. Each stage The slide speed of is accelerated under the influence of gravity, but is adjusted appropriately by the damper 12 The speed is adjusted to reduce the impact. When support leg 5 lands in this way, , the lower tier 4 and the middle tier 3 are bent appropriately at the hinge joints 4c and 3c, as shown in Figure 1. Ladder 1 is placed over the sea urchin. Finally, attach the handrail 11 to complete the emergency ladder. Becomes. (Figure 10).

[0026] When storing the ladder 1, remove the handrail 11 and unlock the support legs 5. Then, rotate the upper step 2c counterclockwise in Fig. 1 to avoid interference with the middle step 3. After that, raise the upper tier 2 to the top of the diagram, and then slide the middle tier 3 and the lower tier 4 in the opposite direction. If so, it can be accommodated.

[0027]

[Effect of the idea]

As explained above, according to the present invention, the emergency ladder can be easily operated by one person. You can simply do it. Also, since they are stacked in a stacked state when stored, the storage space is small. Since the emergency exit is evacuated when not in use, there is no need to block the emergency exit, and the lead vehicle can be repurposed as an intermediate vehicle at any time.
