Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency evacuation device from a high place.

[0002]

2. Description of the Related Art Conventionally, there are ladders, rope ladders and the like as simple tools for evacuating from a high place on their own, and there is a compact emergency evacuation descent as a related tool. Further, as a belt or a belt-like belt, an emergency evacuation descent belt (application number, Japanese Patent Application No. 7-33982) is used.
6) has been filed.

[0003]

The ladder and the rope ladder described in the prior art are extremely inconvenient to carry,
Emergency evacuation descents are expensive. Therefore, an emergency evacuation descent belt using a belt or a belt-like belt (application number, Japanese Patent Application No. 7-339826) has been filed. It is light and compact, so it is easy to carry. In addition, although it is inexpensive, the burden on the limbs is relatively light even when used with bare hands or bare feet, there are many advantages such as easy insertion of the feet into the space, but the following problems are encountered. Having.

[0004] Since an integral portion is provided between the space portions, a step portion of the rope ladder is not required, which saves material. However, when weight is applied to the integral portion, the portion above the portion becomes higher. A belt or belt-like thing (hereinafter referred to as a belt) is tense. For this reason, since both sides of the foot are subjected to great pressure by the belt, there is considerable resistance when pulling out the foot, which is not convenient.

[0005] Further, in the portion where the pulling force due to the weight is applied to the belt, since there is an integral portion, there is no space except for the portion where the foot is put, so that the hand can be put between the belts. Not easy and not easy to use.

For this reason, there is an embodiment in which a notch or a slit is provided in a portion of the belt forming a space portion.
In addition to the increase in man-hours, when the width of the belt is reduced or the thickness of the belt is reduced in order to make the belt compact, a problem in strength occurs.

Although the integral part is formed by sewing or an adhesive, the frictional force between the belt and the belt does not work, so that only the tensile force by the thread or the adhesive is used.
There is a safety problem. Therefore, the integral part needs to be reinforced, which is disadvantageous for compact folding.

The present invention has been made in view of such problems, and aims at sacrificing as much as possible the many advantages of the above-mentioned emergency evacuation descent belt of the present application. Without lowering the limbs into and out of the space during the descent, and eliminating the problem of strength even with the use of a thin and narrow belt, making it safer and more user-friendly. An object of the present invention is to provide an emergency evacuation descent which can be relatively easily climbed.

[0009]

In order to achieve the above object, in the emergency evacuation descent belt (hereinafter referred to as descent belt) of the present invention, a space surrounded by the belts 1 and 2 is formed at an appropriate interval. A required number is formed, and a belt 3 is provided below the belt 2.

When the descending belt constructed as described above is taken out of a bag or a storage case, it is fixed to an appropriate one using a locking portion or a space at one end, and the rest is thrown down. The folded descent belt extends by its own weight. Therefore, the remaining space is automatically formed in a predetermined shape that allows the foot to be easily inserted. Hereinafter, the operation and the like will be described based on embodiments.

When descending, the descending belt swings. It moves because of the wind because it is light, and it moves even if your foot touches the belt lightly. Further, it is very difficult to move the left and right feet alternately and quickly on a straight line. It is extremely inconvenient when descending while visually checking the lower space, and it is important to be able to carry the foot smoothly especially when descending. In order to solve the above problems and to easily put the foot in the space, the opening width in the space may be increased.

However, when a flat, thin and flexible belt is used, the belt 2 hangs down by its own weight. Therefore, since the belts 1 and 1 on both sides move inward, the space is deformed and the opening width is reduced. Further, when the foot is put on the belt 2, the belt 2 is further lowered, and the opening width in the space one step below for the next foot is smaller.
In order to solve this problem, an embodiment in which belts 3 and 3 are provided on both sides below the belt 2 will be described.

In a state where the descending belt is extended only by its own weight, the belts 3 on both sides support the belt 2 to prevent it from hanging down, so that a predetermined opening width is maintained. Next, with reference to FIG. 5, a description will be given of a case where a foot is put on the belt 2. FIG. When the foot is put on the belt 2, the belt 2 is lowered, the space above the portion is deformed, and the opening width is reduced to substantially the width of the foot. However, the belts 1 and 1 on both sides which form the space one step below where the feet are to be put next are pulled diagonally inward and upward and try to move inward. Since the space portion is slightly deformed, the opening width hardly changes, and the space portion below the second stage maintains a predetermined shape.

As described above, the belts 3, 3 on both sides are
Functions to maintain a large opening width in a space where the pulling force due to the weight is not applied to the belt. For this reason, a space surrounded by a belt into which the foot can be inserted very easily is formed. FIG. 6 is an example of a folding method in which the longitudinal direction of the descending belt is compressed, folded in the direction of the arrow, and accommodated, so that the bending tendency of the belt at the time of accommodation is small and the influence on the opening width is reduced. Is shown.

In the embodiment shown in FIGS. 1 and 2, since the load can be applied in either direction of the arrow, there is no problem if the descending belt is used upside down.
In the embodiment shown in FIG. 1, it should be noted that the frictional force between the belts 1 and 1 and the belt 2 on both sides works effectively only in the direction of the arrow.

In the case of a descending belt having two rows of spaces, 1
Although it is disadvantageous in terms of weight and storage compared to the row,
Left and right limbs can be put in and out of each space. The locking portion or the space portion is used as a locking device, and the one having a single space portion is formed as a large locking device by passing one end of the descending belt through the locking portion or the space portion. It works effectively for fastening items and connecting other descent belts.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. In the embodiment shown in FIG. 1, the belts 1 and 1 on both sides are connected by a belt 2 by sewing or the like, and a required number of space portions 4 surrounded by the belts 1 and 2 are formed continuously at appropriate intervals. In addition, belts 3, 3 having both ends connected to the belts 1 and 2 by sewing or the like are provided below the belt 2.

In the embodiment shown in FIG. 2, a belt 3 whose both ends are connected to the belts 1 and 1 on both sides by sewing or the like is provided below the belt 2.

In the embodiment shown in FIG. 3, belts 3 having relatively large elasticity are attached to belts 1 and 1 on both sides at the lower portion of belt 2 by sewing or the like. Although the same function as the belt 3 can be achieved by using a leaf spring or another elastic body, it is disadvantageous in terms of compact folding and storage.

The embodiment shown in FIG. 4 is different from the embodiment shown in FIG. 1 in that one of the belts 1 is extended and a locking portion 5 is formed by sewing or the like at the extended portion. If there is no problem, a slit or a long hole may be provided in the extended portion.

When the space portion 4 implements two rows of descending belts, the space portion 4 may be formed by bonding two adjacent belts 1 and 1 in one row by sewing or the like. Or, as another embodiment, adjacent belts 1 and 1
And the spaces 4 can be arranged in two rows.

In the above embodiment, belts 1 and 2
The flat belt is used to store the descent belt compactly and store it by its own weight from the folded state at the time of use. The belt 3 is preferably thin and flexible, and the belt 3 is desirably relatively elastic. If there is no problem in strength, a tape or ribbon-like material may be used. In particular, it is more preferable to perform a flameproof process so as to withstand use at a fire site or to use a heat-resistant material. Also, it is convenient to use a fluorescent paint or adhere a reflective tape at nighttime use. And belts 1 and 2
If the lowering belt can be formed integrally or the entire descending belt can be formed integrally and three-dimensionally, bonding and connection work are not required, and large labor saving can be expected.

[0023]

Since the present invention is configured as described above, it has the following effects.

[0024] Even in the space where the pulling force due to the weight is applied to the belt, an opening width substantially corresponding to the width of the foot can be ensured. It is easy to use because it can be easily put in and out.

Furthermore, since the hands and arms can be very easily taken in and out between the belts, the power of the hands and arms can be sufficiently used even by a person with a weak grip, so that it is more convenient than a rope ladder and safer from a high place. Can descend.

Further, since it is not necessary to provide a notch or a slit in the belt 1 forming the space in order to improve the usability, the belt can be made thinner, the width can be made smaller, and the number of man-hours can be reduced. .

The connection between the belts 1 and 2 is configured to apply a large frictional force and can withstand a large pulling force, so that it is extremely safe. Therefore, no special reinforcement is required.

Further, even in the space where the pulling force due to the weight is applied to the belt, an opening width substantially corresponding to the width of the foot can be secured, so that it is relatively easy not only to descend but also to ascend. it can.

Although the two-row space portion has some drawbacks in carrying as compared with the one-row space portion, since both hands and feet can be put in each space portion, the foot can be carried more smoothly. In other words, the burden on the limbs is smaller, and climbing and lowering is easier.

In addition to the above-mentioned effects, the present invention has the effects of the above-described descending belt of the present application. If the effect is also described below, the belt that hits the sole and both sides of the foot is symmetrical left and right, so there is almost no deformation of the belt, and the width of the belt can be used effectively, so make the thickness thinner, make the width smaller However, there is no pain because the pressure on the feet is small. And the one with one space is
A substitute for a rope is also possible.

Further, since the locking portion and the space portion can be used as a locking tool, no special locking tool is required. In the case of a single row of space, a large locking tool can be easily made.
The body of an infant, an old man or a sick person can be easily fixed and lowered. Then, the plurality of descending belts can be extremely easily and reliably connected to each other by using the locking portions and the space portions, and can be made long. It is also cheaper and easier to produce than emergency evacuation aircraft. And it is light and compact, so it is convenient to carry.
