Description

[Detailed Description of the Invention] This invention relates to a suspension device for manually dropping the rescue bag outdoors, which is prescribed by the Fire Service Law Circulation Regulations.

First, an outline of this type of suspension device will be explained.

Figure 1 shows a suspension device for a rescue bag, where 1 is a suspended rescue bag, 2 is a suspension bracket that holds the rescue bag suspended, 3 is a support frame that supports this suspension bracket, and 4 is a frame installed on building H. This is a mounting frame for storing the rescue bag 1, the suspension fittings 2, and the support frame 3. The support frame 3 is supported by the installation frame 4 and is configured to be able to be pulled upward by human power.

In the above device, the rescue bag 1 to be dropped is attached to the suspension fitting 2.
Since the metal fittings 2 are attached to the support frame 3, when lifting and setting the support frame 3, the rescue bag must also be lifted at the same time. The disadvantage was that the rescue bag had to be lifted, which was extremely difficult.

In order to eliminate the above-mentioned drawbacks, this invention temporarily stops the fall of the rescue bag after it is dropped, reduces the weight of the rescue bag acting on the support frame, reduces the weight when lifting the support frame, and makes it easier to lift. That is.

An embodiment of this invention will be described below with reference to the drawings.

Figure 2 shows the support frame being pulled up after the rescue bag has been dropped outside the building and the fall of the rescue bag is temporarily stopped by the locking mechanism, and Figure 3 shows the support frame in its designated position. This figure shows the situation immediately after the bag has been pulled up, the locking mechanism has been released, and the rescue bag has started to fall again. 6 is a partial enlarged view of section B in FIG. 3.

In these figures, the same parts as those shown in FIG. 1 are designated by the same reference numerals, and their explanations will be omitted.

5 is a rail provided on the top of the mounting frame 4 and serves as a guide when lifting the support frame 3; 6 is a pair of horizontal bars 41 of the mounting frame 4;
It is rotatably attached to the support frame 3 by a shaft 7, moves as the support frame 3 rises to a predetermined position, and engages with the lower end of the support frame 3 as shown in FIG. 6, thereby preventing the support frame from falling. A stopper 8 is a spring that provides a force for rotating the stopper 6 in the direction of arrow C, and 9 is rotatably attached to the rail 5 on the mounting frame 4 by a shaft 11. In the state before the stopper 6 is activated, As shown in FIG. 4, one end of the arm portion 13 is a first trigger that contacts the stopper 6 and is restricted from rotating in the arrow direction (shown in FIG. 6), and has a retaining protrusion 12 in the middle. We are prepared.

Reference numeral 10 denotes a second trigger, which is rotatably attached to the rail 5 above the first trigger 9 by a shaft 14, and in a state before the stopper 6 is activated, the first trigger is closed as shown in FIG. 9 and are associated with each other so as to prevent rotation in the direction of arrow E shown in FIG.

15 is a holding belt whose one end is attached to the rescue bag 1, and the other end is a second holding belt which is engaged with the first trigger.
The trigger 10 is removably engaged and held.

Next, the operation of the above configuration will be explained.

In an emergency such as a fire, when a user drops one end of the rescue bag 1 outside the building, the rescue bag 1 is held by the holding belt 15 that is locked by the first and second triggers 9 and 10, and the fall is stopped. .

Next, the support frame 3 housed in the mounting frame 4 is manually pulled up, and when the support frame 3 rises to a predetermined position, the stopper 6 is rotated in the direction of arrow C in FIG. 6 by the force of the spring 8, and the support frame 3 is It enters below and prevents the support frame 3 from falling.

Due to this movement of the stopper 6, the first trigger 9 loses its support and rotates about the shaft 11 in the direction of the arrow in FIG.

As a result, the second trigger 10 also loses its support and rotates about the shaft 14 in the direction of arrow C in FIG. Then, the remaining part of the rescue bag 1 is also pulled out by the falling blade of the bag, and the suspension fittings 2 are expanded, so that it is in a usable suspended state as shown in FIG.

As described above, according to this invention, when the rescue bag is needed, it is possible to lock the rescue bag once and lift the support frame without dropping the entire rescue bag, so that when the support frame is lifted after all the rescue bags have been dropped, the support frame can be lifted. Compared to the previous model, the weight to be lifted is reduced and it can be easily operated.

Moreover, since the release of the rescue bag is linked to the movement of the stopper that prevents the support frame from falling, it is possible to reliably prevent the rescue bag from restarting falling while the support frame is in the middle of being raised.

[Brief explanation of the drawing]

FIG. 1 is a perspective view schematically showing a state in which the rescue bag is dropped and suspended outdoors from a building or the like. Figure 2 shows the support frame being pulled up after the rescue bag has been dropped outside the building and the fall of the rescue bag is temporarily stopped by the locking mechanism, and Figure 3 shows the support frame in its designated position. Figure 4 is a partially enlarged view of section A in Figure 2, and Figure 5 is a partial enlargement of part A in Figure 4. 6 is a partial enlarged view of section B in FIG. 3. In the figures, the same symbols indicate the same parts, 1 is a rescue bag, 2 is a suspension fitting, 3 is a support frame, 4 is a mounting frame, 6 is a stopper, 9 is a first trigger, 10 is a second trigger 15 is a holding belt It is.
