More specifically, in the invention disclosed in Patent Document 1, there is only one loop-shaped flap 30 through which the mounting rod 32 is inserted, and the width of the flap 30 substantially matches the width of the entrance / exit. Therefore, the invention disclosed in Patent Document 1 can only be attached to the entrance / exit having a specific width. That is, when the invention disclosed in Patent Document 1 is to be attached to an opening having a width narrower than the width of the entrance / exit disclosed in Patent Document 1, a product fitted to the width of the opening is manufactured separately. There is a need. Thus, in the case of the invention disclosed in Patent Document 1, there is a problem that versatility with respect to the width of the opening is low.
For this reason, when referencing Patent Document 1, it is necessary to specially order the chute according to the width of the opening to be installed, and it is difficult to reduce the manufacturing cost, and the chute with respect to the width of the opening. The problem of low general versatility still remained.

A portable chute 1 according to the present embodiment is a chute that is detachably installed in an opening for evacuation, and includes an air chamber 2 that expands by injecting gas from the outside, and an extension of the air chamber 2. A plurality of loops 6 (loops 6a to 6d) provided on one end 3a side in the direction, and the air chamber 2 passed through the loop 6 and indirectly to the evacuation opening (see FIG. 3 shown below) It is comprised by the rod body 11 latched.
The air chamber 2 according to the present embodiment is used, for example, by injecting and inflating gas with an air supply device such as a cylinder. For this reason, the air chamber 2 which concerns on this Embodiment is provided with the connection part 7 for connecting the air supply piping provided in an air supply apparatus in the air chamber 2. FIG. In addition, the portable chute 1 according to the present embodiment can be regarded as a concept including an air supply device in addition to the air chamber 2 and the rod body 11 provided with the loop 6.

In the portable chute 1 according to the present embodiment, gaps are formed between the individual loops 6a to 6d constituting the plurality of loops 6 installed on the one end 3a side of the air chamber 2. As a result, the gap between the loops 6a to 6d can be narrowed. Thereby, the width | variety in the plane direction by the side of the one edge part 3a of the air chamber 2 can be narrowed. Specifically, there is a case where the space between the individual loops 6a to 6d is narrowed, and the air chamber 2 is lowered from the center as much as possible, for example, and deformed three-dimensionally from a planar shape.
Further, in the portable chute 1 according to the present embodiment, when one end 3 a of the air chamber 2 includes three or more loops 6, the number of the loops 6 that pass through the rod body 11 can be reduced. The width in the plane direction of the air chamber 2 can be reduced. This method will be described in detail later with reference to FIG.
In FIG. 1, the case where four loops 6 are formed is described as an example. However, as long as two or more loops 6 are provided, the number of loops 6 may not be particularly specified.

FIG. 2 is a cross-sectional view of the trunk portion of the portable chute according to the embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the part same as what was described in FIG. 1, and the description about the structure is abbreviate | omitted.
The air chamber 2 according to the present embodiment may be configured by integrating a plurality of tube-shaped air chambers 2a to 2d in parallel as shown in FIGS.
In this case, although not particularly illustrated, when the hollow portions of the individual air chambers 2a to 2d are communicated and the gas is supplied from the connecting portion 7, the gas is supplied to all the air chambers 2a to 2d. It should be configured. Of course, the connection part 7 may be provided in each of the air chambers 2a to 2d so that gas can be individually supplied to each of the air chambers 2a to 2d.
Furthermore, in this Embodiment, when the air chamber 2 is comprised by several air chambers 2a-2d, the case where the shape of each air chamber 2a-2d is made into a cylindrical shape (a substantially cylindrical concept is also included). Although described as an example, the external shape of each of the air chambers 2a to 2d is not necessarily specified as illustrated. However, since the evacuees slide down on the air chamber 2 and escape, it is desirable that the individual air chambers 2a to 2d have a gentle shape so as not to hinder the escape of the evacuees.

In addition, as shown in FIGS. 1 and 2, the portable chute 1 according to the present embodiment is disposed on the upper surface of the air chamber 2, that is, in a direction perpendicular to the extending direction of the rod 11 and the air chamber 2. A trough 8 that allows the air chamber 2 to be bent may be provided on the upper surface side.
In this case, when the gaps between the individual loops 6 (loops 6a to 6d) are narrowed, the air chamber 2 is narrowed so that the side edges 13a and the side edges 13b of the air chamber 2 are narrowed, as indicated by reference numeral B in FIG. Can be bent and deformed.
As a result, the width C in the plane direction on the one end 3a side of the air chamber 2 can be easily reduced.
In FIGS. 1 and 2, an example is described in which one end 3 a of the air chamber 2 is provided with four loops 6 (loops 6 a to 6 d), but one end of the air chamber 2 is described. When the number of loops 6 attached to 3a is 2, the effect of narrowing the width C of one end 3a of the air chamber 2 as described above can be easily exhibited.

Furthermore, as shown in FIG. 2, the portable chute 1 according to the present embodiment may have a vertical cross-sectional shape in the extending direction of the air chamber 2 in a concave shape.
In this case, a groove-like recess 9 is formed at the center of the air chamber 2 in the extending direction. That is, the side edges 13 a and 13 b of the air chamber 2 are higher than the central portion of the air chamber 2.
In this case, when the user slides down on the portable chute 1 according to the present embodiment and evacuates, the user slides down the recess 9. In this case, the risk that an evacuee falls from the side edges 13a and 13b of the air chamber 2 can be greatly reduced.
By providing such a recess 9, the safety of the portable chute 1 according to the present embodiment can be further improved.

Here, a method of using the portable chute 1 according to the present embodiment will be described with reference to FIG.
FIG. 3 is a conceptual diagram showing a use state of the portable chute according to the embodiment of the present invention. The same parts as those described in FIGS. 1 and 2 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 3, the portable chute 1 according to the present embodiment evacuates from an opening 10 provided at a position vertically higher than the installation surface 12 where the other end 3 b of the air chamber 2 contacts the ground. It is an evacuation tool to escape the person.
Such a portable chute 1 according to the present embodiment has a rod 11 inserted through a loop 6 (loops 6a to 6d) provided on one end 3a side of the air chamber 2, and then the rod 11 Is disposed on the indoor side of the opening 10, the left and right ends of the rod 11 are locked inside the left and right edges 10 a and 10 b of the opening 10, and the air chamber 2 is moved out of the opening 10. It is extended and used like a slide.

In this case, by making the length of the rod 11 sufficiently longer than the width of the opening 10 in the left-right direction, there is no provision of any fixing structure for fixing the rod 11 inside the opening 10. The portable chute 1 can be fixed to the opening 10.
This means that the portable chute 1 according to the present embodiment can be detachably installed in the opening 10. Further, it means that the portable chute 1 according to the present embodiment can be assembled and carried differently from a chute installed at an evacuation exit of a conventionally known aircraft or the like.
That is, the portable chute 1 according to the present embodiment is provided not as a thing that can be used only for a specific evacuation opening but as a highly versatile evacuation tool that can be used in openings of various widths. can do.

As shown in FIGS. 1 and 3, the planar shape of one end 3 a of the portable chute 1 according to the present embodiment may be a concave shape. That is, both the left and right side edges 13a and 13b on the one end 3a side of the air chamber 2 are projected into the projections 5 and 5, and a plurality of recesses 4 formed between the projections 5 and 5 are provided. The loop 6 (loops 6a to 6d) may be provided.
In this case, as shown in FIG. 3, when the portable chute 1 according to the present embodiment is installed in the opening 10, the protrusions 5, 5 formed on the one end 3 a side of the air chamber 2 are , The edges 10a and 10b of the opening 10 and the outer periphery thereof are pressed against each other and act to press the portable chute 1 against the lower installation surface 12, while the rod 11 has a portable chute via the loop 6. It acts to add a reaction force that raises 1. Accordingly, the rod body 11 is pressed against the inside of the opening 10 by the action of the protrusions 5 and 5, and can be prevented from coming off due to vibration or the like generated when the evacuees escape from the opening 10. .
Further, when the protrusions 5 and 5 are pressed against the edges 10a and 10b of the opening 10 and the outer periphery thereof, the side edges 13a and 13b are lifted by the reaction force, so the protrusions 5 and 5 and the edge 10a , 10b function as a side guard or a handrail when the evacuee escapes from the opening 10 by sliding down the portable chute 1.
Of course, when the width of the opening 10 is wider than the width of the air chamber 2, the protrusions 5 and 5 cannot be pressed against the edges 10a and 10b and the outer periphery thereof. , 5 are accommodated in the opening 10, the side edges 13 a, 13 b of the air chamber 2 extending to the protrusions 5, 5 are the central portion of the air chamber 2 (corresponding to the recess 9). Since it is slightly higher than that, it can function to some extent as a side guard for evacuees.
That is, in both cases, the protrusions 5 and 5 are arranged on the upper side of the rod body 11 so that both the left and right side edges 13a and 13b of the air chamber 2 are directed upward, and function as a side guard or a handrail. .
Therefore, by providing the protrusions 5 and 5, the safety of the portable chute 1 according to the present embodiment can be further enhanced.

Further, as shown in FIGS. 1 and 3, the other end 3 b side of the air chamber 2 of the portable chute 1 according to the present embodiment is partially bent or curved so as to be along the installation surface 12. You may keep it.
In this case, when the other end 3 b of the air chamber 2 is bent or curved along the installation surface 12, when the portable chute 1 according to the present embodiment slides down and evacuates, the other end The speed of the evacuees who have reached the vicinity of 3b can be reduced. As a result, the evacuees can be safely removed from the air chamber 2.
In addition, even when the other end 3b of the air chamber 2 of the portable chute 1 according to the present embodiment is not bent or curved as shown in FIGS. .
In this case, since the length in the extending direction of the air chamber 2 can be maximized, the portable chute according to the present embodiment can be used in various evacuation openings where the height difference from the opening 10 to the installation surface 12 is not uniform. 1 The possibility that it can be used increases.
That is, when the difference in height from the opening 10 to the installation surface 12 is small, the angle formed by the air chamber 2 with respect to the installation surface 12 can be reduced, that is, the inclination of the air chamber 2 can be made gentle. On the other hand, even when the height difference from the opening 10 to the installation surface 12 is large, although the angle formed by the air chamber 2 with respect to the installation surface 12 is large, that is, the air chamber 2 is steeply inclined, but the air chamber 2 Since the inclination of the air chamber 2 can be made gentler than when the other end 3b is bent or curved, the evacuee can be evacuated using the portable chute 1 in this case as well.
That is, in the portable chute 1 according to the present embodiment, when the one end 3a of the air chamber 2 is bent or curved, the height difference from the opening 10 to be installed to the installation surface 12 is constant. It is a form particularly suitable for use in the case of (uniform). On the other hand, in the portable chute 1 according to the present embodiment, one end 3a of the air chamber 2 that is not bent or curved is the difference in height from the opening 10 to be installed to the installation surface 12. It is a form suitable for use when is not uniform.

As described above, when the portable chute 1 according to the present embodiment is provided as a highly versatile one that can be used in various evacuation openings, the book is provided in the opening 10 having a non-uniform width. The problem is how to fit the air chamber 2 according to the embodiment.
As shown in FIG. 3, the portable chute 1 according to the present embodiment allows the rod body 11 to be inserted into the plurality of loops 6 formed on the one end 3a side of the air chamber 2. Since the rod 11 is configured to be locked and fixed to the opening 10, the air chamber 2 can be attached to the opening 10 when the width C in the plane direction of the air chamber 2 cannot be changed. It is not possible.
In view of such circumstances, in the portable chute 1 according to the present embodiment, the above-described problems are solved by configuring the width in the planar direction of one end 3a of the air chamber 2 to be changeable.

Hereinafter, an example of how to narrow the width C in the planar direction of one end 3a of the air chamber 2 of the portable chute 1 according to the present embodiment will be described in detail with reference to FIG.
In the portable chute 1 according to the present embodiment, as described above, as a method of narrowing the width in the planar direction of one end 3a of the air chamber 2, a gap is formed between the loops 6 in advance. A method of narrowing the gap between the loops 6 with the rod 11 inserted through the loops 6 (loops 6a to 6d) can be considered. In this case, the air pressure in the air chamber 2 is not so high, and one end 3a side of the air chamber 2 needs to be able to be deformed as desired. However, when the pressure in the air chamber 2 is low, there is a concern that the rigidity of the air chamber 2 is reduced and sufficient safety cannot be ensured during evacuation.
For such a problem, the air chamber 2 in the vicinity of the one end 3a side and the other air chamber 2 are partitioned, and a structure in which gas cannot flow back and forth between the respective partitions. A solution is possible. However, in this case, it is necessary to provide the connection part 7 in each section separately and to feed the gas. Such a structure takes time during assembly and is particularly troublesome in an emergency. Therefore, it is desirable that the air chamber 2 be easily folded even when the air pressure in the air chamber 2 is sufficiently high.
In view of such circumstances, the usage form of the portable chute 1 according to the present embodiment as described below has been developed.

FIG. 4 is a partial conceptual view showing a modification of the usage state of the portable chute according to the embodiment of the present invention. The same parts as those described in FIGS. 1 to 3 are denoted by the same reference numerals, and description of the configuration is omitted. FIG. 4 is viewed from the direction indicated by the symbol P in FIG. Further, in FIG. 4, the description of the air chambers 2a and 2d shown in FIGS. 1 to 3 is omitted.
As shown in FIG. 4, in order to narrow the width C of the portable chute 1 according to the present embodiment, the loop 6 a among the loops 6 a to 6 d installed on the one end 3 a side of the air chamber 2. 6d, the rod 11 is inserted into the loops 6b and 6c, and the rod 11 is locked to the opening 10 in this state.
In this case, since the rod 11 is not inserted into the loops 6 b and 6 c, the air chamber 2 can be easily bent along the valley portion 8. In this case, the width C of the air chamber 2 can be easily reduced as compared with the case where the rod 11 is inserted through all the loops 6a to 6d.
Further, in this case, since the air chamber 2 is in a state in which a depression is formed on the upper surface side and along the extending direction, when the evacuee slides down on the air chamber 2, the body of the evacuee in the air chamber 2. Can be held. As a result, even when the width C of the air chamber 2 is narrowed, the evacuees can be evacuated from the opening 10 safely.
Even when the number of loops 6 inserted through the rod 11 is reduced, the loop 6 is connected to one end of the air chamber 2 so that the connection portion of the loop 6 can sufficiently withstand the load of the refugee and the air chamber 2. Needless to say, it is necessary to attach it firmly to 3a.

As described above, according to the portable chute 1 according to the present embodiment, the width in the planar direction of the one end 3a of the air chamber 2 can be reduced as necessary, so that the opening 10 to be attached is provided. The versatility of the portable chute 1 with respect to the width can be enhanced.
Therefore, for example, when a chute is attached to the opening 10 for an unexpected accident or disaster in a train or the like, there is no need to install a stationary chute on all the openings 10 of the train.

Finally, a modified example of the connecting portion 7 of the portable chute 1 according to the present embodiment will be described with reference to FIG.
Fig.5 (a) is a side view of the connection part of the portable chute concerning embodiment of this invention, (b) is the mesh material provided in the connection part of the portable chute concerning embodiment of this invention. It is a conceptual diagram. The same parts as those described in FIGS. 1 to 4 are denoted by the same reference numerals, and description of the configuration is omitted. Moreover, Fig.5 (a) is an AA arrow directional view in FIG.
As shown in FIGS. 5A and 5B, the portable chute 1 according to the embodiment of the present invention may include a mesh material 14 inside the air chamber 2 of the connection portion 7.
As described above, as a means for supplying air to the air chamber 2 of the portable chute 1 according to the present embodiment, it is assumed that a gas cylinder is used. Usually, the pressure of the gas supplied from the gas cylinder is about 14 MPa, and if the gas is supplied into the air chamber 2 as it is, there is a possibility that the air chamber 2 may be damaged due to a high pressure acting locally on the air chamber 2. It was.
On the other hand, as shown in FIGS. 5A and 5B, when the connecting portion 7 of the air chamber 2 includes the mesh material 14, high-pressure gas will flow into the air chamber 2 vigorously from the connecting portion 7. When this is done, the gas is dispersed upon striking the mesh material 14, so that high pressure can be prevented from acting locally on the air chamber 2. Thereby, when expanding the air chamber 2 using a gas cylinder, it can prevent that the air chamber 2 is damaged. That is, the mesh material 14 functions as a diffusion unit for the gas to be discharged.

Further, as shown in FIGS. 5A and 5B, the shape of the mesh material 14 is not a flat plate but a three-dimensional cage, so that gas is also generated in the vicinity of the connection portion 7 in the vicinity thereof. It can be distributed and supplied. That is, even if the gas supplied from the connecting portion 7 is high pressure, the gas can be supplied from the connecting portion 7 into the air chamber 2 while being dispersed in a three-dimensional direction instead of being linear. That is, by using the mesh material 14, the gas can be quickly supplied also to the vicinity of the connection portion 7.
Further, by providing such a basket-like mesh material 14 in the connecting portion 7, a gap is formed between the sheet materials constituting the air chamber 2 even when the gas is extracted from the air chamber 2. Can do. In this case, there is also an advantage that the inflow of gas from the connection portion 7 into the air chamber 2 can be performed smoothly.
