JPS5829758Y2 - Balcony evacuation device - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a balcony evacuation device.

Conventional balcony evacuation devices have been known to have a hatch attached to the floor and a ladder attached below.

However, with this structure, 1) there is a risk that a child may fall if the hatch is accidentally lifted; 2)
If the ladder is locked to avoid this danger, it will slow down operation in an emergency, which is undesirable. 3) Since the ladder is fixed even in normal times, it is easy for thieves to break into it.

There were problems such as... The present invention was devised to solve the problems of the prior art, and aims to provide an easy-to-operate, safe and reliable evacuation device. Let's discuss an example.

A is a balcony.

1 is a balcony Kasagi 2 is a frame, and a baluster 3 is attached between the two.

4 is a fixed support, 5 is a movable support of the folding ladder that constitutes the present invention, and 6 is a fixed support of the folding ladder.

A step 7 is foldably supported between the movable column 5 and the fixed column 6.

8 is a panel fixed to a position slightly below the upper end of the movable column 5.

This panel normally constitutes a part of the baluster on the wall W side of the balcony Δ.

Therefore, the part corresponding to this panel 8 is omitted from the baluster 3 of the balcony A.

Reference numeral 9 denotes a holding metal fitting attached to the frame 2, which holds the side frame 8a of the panel 8 when the ladder is opened, and prevents the ladder from wobbling.

Reference numeral 10 denotes a support fitting provided at the top of the panel 8. In order to prevent the ladder from swaying when the ladder is folded and the panel is closed, the support attached to the Kasagi 1 side of the balcony engages with the metal fitting 11. ing.

Reference numeral 12 denotes a latch fitting attached near the upper end of the movable column 5, and when the ladder is closed, it is hooked onto a hooking device (not particularly shown) provided at the upper part of the fixed column 6 to maintain the closed state.

A pull string 13 is attached to the upper end of the fixed support 6, and when pulled, the latch fitting 12 is removed, the movable ladder 5 is lowered, and an evacuation ladder is automatically formed.

Note that the tension edge 13 is provided at a position out of the reach of children.

With the above configuration, to lower the closed evacuation ladder to the state shown in Figure 1, operate as follows.

(i) Pull the tension edge 13 toward you to secure the latch fitting 12.

Then, the movable support 5 descends and its lower end lands on the ground.

At the same time, step 7... is also opened to form a ladder.

At this time, the panel 8 also moves, so the top step 7a
Space B will be formed above, so you can evacuate from here.

When the panel 8 is opened to the state shown in FIG.
It is safe because the open position is maintained.

(ii) To store the open ladder in the state shown in FIG. 2, it is preferable to lift the movable column 5 upward and hang the latch fitting 12 on the hooking device.

At this time, the holding fittings 10 and 11 are also engaged as shown in FIG. 5, so that the ladder is prevented from swinging sideways and is firmly held on the wall surface W (see FIG. 1).

According to the present invention, (a) the ladder can be opened with one touch by using a folding ladder and pulling a tension cord, so that easy and reliable operation is possible.

(b) When the ladder is closed at all times, the panel forms part of the balcony, so it is not particularly noticeable and does not cause any problems in terms of design.

(C) Since the panel forms part of the balcony, this part serves as an evacuation exit when opened, making it easy to evacuate.

(d) Since it is structurally simple, it can be provided at low cost.
