Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage device for evacuation equipment, and in particular, it is stored inside the handrail of a building's veeranda, and when one person is using the evacuation equipment, a support 1 is placed outside the upper part of the handrail to store the evacuation equipment in the veeranda on the lower floor. This invention relates to a storage device that allows evacuation equipment to be extended and stacked.

First, this kind of storage device and 1, t, folding mat, knee j1
．． When using the embryo, the storage case that stores the extendable evacuation equipment is stored inside the handrail of the Veeranda in an upright position approximately parallel to the handrail. The end side is supported by an arm pivotally connected to the base of the veeranda, and the base end is latched to the handrail, and this storage case is supported in a substantially horizontal state to extend the evacuation equipment toward the veeranda on the lower floor. I came up with one idea.

・However, in such conventional storage devices, the storage case does not always move in a constant trajectory when the storage case is lifted out from the top of the handrail. Careful operation was required to ensure that the hook was securely latched to the handrail.

Therefore, in case of an emergency, evacuees who are in a panic may find it difficult to carry the storage case outside above the handrail.
The operation of locking the proximal end portion to the handrail is a heavy burden and may be a time-consuming operation.

In view of the problems with the conventional storage devices, the present invention provides a storage device for evacuation equipment in which the storage case is always taken out above the handrail in a constant trajectory.

Hereinafter, the invention of (-) will be described in detail based on the embodiments shown in the accompanying drawings.

A storage device according to this embodiment is shown in FIGS. 1 and 2.

This storage device has a frame 12 erected inside the handrail 4 of C゛Elanda 3.
A first pool 5 is disposed in the frame 12, which is rotatably attached to a support bracket 13 (pivot point P1), and whose tip extends above the handrail 4. The storage case 2 is arranged in an upright state, and the tip of the storage case 2 projects above the handrail 4, and a support arm 14 is provided projecting from the tip to extend outward from above the handrail 4. The tip of this support arm 14 and the tip of the first arm 5 are pivotably connected to each other at a pivot point P4), and one end is connected to a bracket 27 provided on the base end side of the force storage case 2. The other end of the movably pivoted nearer end is pivotally connected to the frame 12, and at least the frame 1 of this nearer end is pivotally connected to the frame 12.
The pivot point P2 on the second side is located higher than the pivot point P3 on the storage case 2 side, thereby forming a four-bar link mechanism consisting of the first arm 5, the storage case 2, and the second nearer arm. When using the evacuation device 1 which is constructed and housed in the storage case 2 and is expandable and retractable in multiple stages, the storage case 2
It is formed so that it can be lifted outward from the upper part of the handrail 4 while always drawing a constant trajectory and supported in a substantially horizontal state as shown by the two-dot chain line.

Therefore, according to the storage device of this embodiment, in order to move the storage case 2 from the storage state indicated by the solid line in FIG. All you have to do is bring it out from above, and at this time,
Since the storage case 2 is supported by the first arm 5 and the second arm, the front end of the storage case 2 is a pivot point P where the first arm 5 is pivotally connected to the support bracket 13.

The base end side of the storage case 2 rotates around the pivot point P2, which is pivoted to the frame 12. Guided by the 5th and 4th near-muro, the erection moves along a certain trajectory, and the 5th near-muro comes into contact with the Kasagi 36 located at the top of the beckoning 4 and stops, and the storage case 2 is moved as shown by the imaginary line. The first arm 5 and the second arm 5 support the upper part of the handrail 4 outwardly in a substantially horizontal state.

At this time, since the pivot point P2 on the frame 12 side of the near irregularity is located at least higher than the pivot point P3 on the storage case 2 side, when the storage case 2 is lifted, the pivot point P2 on the frame 12 side rotates at a faster speed than the first arm 5.

For this reason, the storage case 2 to which the near-muro is pivotally attached
The base end side (pivot point P3) moves faster than the distal end side (pivot point P4) of the storage case 2 to which the first arm 5 is pivotally connected, and the storage case 2 The storage case 2 is lifted up until it becomes almost horizontal and then taken out from the upper part of the handrail 4, thereby avoiding contact between the storage case 2 and the handrail 4.

Also, in order to move from this usage state to the storage state,
When the storage case 2 is pulled inside the handrail 4, the storage case 2 follows a constant trajectory, which is completely opposite to the case where the storage case 2 is moved to the above-mentioned usage state while being supported by the first arm 5 and the second near arm. The first arm 5 moves while drawing and stops when it comes into contact with the cap 36 located at the top of the handrail 4, and the storage case 2 is stored inside the handrail 4 in an upright state substantially parallel to the handrail.

For this embodiment, an auxiliary ladder 15 that is extendable and retractable in the shape of a pantograph is provided at the bottom of the storage case 2 housed in the frame 12, as shown in FIG. The upper end is fixed to the storage case 2, and the lower end is fixed to the frame 12, which extends when the storage case 2 is brought out above the handrail 4, and is supported approximately horizontally from the Veeranda 3 along the handrail 4. The hanger is placed in the storage case 21 that is provided.

Therefore, according to the evacuation equipment storage device according to this embodiment, as shown in FIGS. When the evacuation device 1 is carried out toward the side, the auxiliary ladder 15 is extended along the handrail 4, and each vertical bar 34 of the evacuation device 1 stored in the storage case 2 is extended, as shown in FIG.

In this embodiment, an auxiliary platform 32 and a small ladder 33 are provided at the bottom of the evacuation device 1, and when the vertical bars 34 of the evacuation device 1 are extended, the auxiliary platform 32 engages with the handrail 31 on the lower floor. Then, from the tip of this auxiliary stand 32 to the handrail 3 on the lower floor
A small ladder 33 is vertically installed inside the ladder 1.

The evacuation equipment 1 used for this example is the third
As shown in the figure, a plurality of hollow vertical bars 34 having an elliptical cross section with different diameters are fitted and connected to each other, and a step plate 35 extending in the short diameter direction is provided at the lower end of each hollow vertical bar 34 to form a ladder shape. The upper end of the hollow vertical bar 34a located at the top is pivoted to the tip side of the storage case 2, and when not in use, it is reduced together with the auxiliary stand 32 and the small ladder 33 to form the storage case. 2, and is formed so as to extend toward the handrail 31 on the lower floor when in use.

In addition, in order to return the evacuation device 1 from the usage state shown in FIG. 3 to the stored state of the storage case 2 shown in FIG. This evacuation device 1 is reduced by a hoisting device (not shown) or the like, and the auxiliary stand 32 and small ladder 33 are folded back to be substantially parallel to the evacuation device 1 and stored in the storage case 2.

Next, if you hold the base end of the storage case 2 and pull it toward the inside of the handrail 4, the storage case 2 will move accurately into the frame 12 while drawing a constant trajectory using the first arm 5 and the second near-edge. is stored in

Since the evacuation equipment storage device according to the present invention is configured as described above, the storage case 2 is stored inside the handrail 4 in an upright state substantially parallel to the handrail 4 when not in use. The space required to install the device is small, and the Veeranda 3 does not become narrow, and the storage case 2 always moves in a constant trajectory with the first arm 5 and the second nearer arm while the handrail 4 is closed. Since the upper part of the storage case 2 is lifted outward and supported in a substantially horizontal state, the evacuation equipment 1 inside this storage case 2 can be reliably hung vertically toward the handrail 31 on the lower floor even if an evacuee operates it in a hurry during an emergency. In addition to being able to
Pivot point P located at or near handrail 4 of the near-muro
2 is located above the pivot point P3 located on the proximal end side of the storage case 2, so the second frame 6 pivots faster than the first frame 5, and the storage case 2 moves toward the outside of the upper part of the handrail 4. When it is brought out, it is brought out almost horizontally,
Because it does not touch the handrail 4, the handrail 4 and storage case 2
damage can be prevented.

In the above embodiments, the evacuation equipment has been described as a telescopic ladder-like evacuation equipment, but the present invention can also be applied to foldable evacuation equipment.
