Escape routes and high-altitude escape devices

Abstract

This invention discloses an escape belt and a high-altitude escape device, including a webbing and a foot pedal. The webbing has a jump-off section. The foot pedal includes a first cover and a second cover. The first cover enters the jump-off section to open it, and the second cover covers the first cover, with the non-jump-off portion of the webbing penetrating the second cover. This invention, with its jump-off section on the webbing, the first cover opening the jump-off section, and the second cover covering the first cover, allows for connection between the webbing and the foot pedal without damaging the webbing. This not only maintains the load-bearing capacity of the escape belt but also ensures the webbing is tear-resistant, safe to use, durable, and easy to promote.

Description

Technical Field

[0001] This invention relates to the field of high-altitude escape technology, specifically to escape belts and high-altitude escape devices. Background Technology

[0002] As more and more people live in high-rise buildings, the number of escape devices for emergencies such as fires is also increasing. In practical use, people can create escape devices according to actual usage scenarios to meet the needs of different building heights. For example, escape belts or escape ladders (strip-shaped) have a relatively simple structure and are very effective when used with protective devices. However, escape belts or escape ladders (strip-shaped) currently on the market have the following problems: the connection between the connecting belt and the foot pedal is often achieved by damaging the connecting belt. In other words, the connecting belt and foot pedal are currently damaged during the connection process. For example, the connecting belt is riveted to the foot pedal. Once the connecting belt is damaged, its load-bearing capacity will decrease. For example, the load-bearing capacity of the connecting belt is 10 tons when it is intact, but once multiple points of the connecting belt are damaged, its load-bearing capacity will definitely be less than 10 tons. Secondly, the riveted joints between the connecting belt and the foot pedal are prone to tearing after long-term use, resulting in a short service life. If not repaired or replaced in time, they may break when used at heights, posing a significant safety hazard.

[0003] Therefore, in order to solve the above-mentioned technical problems, the present invention provides an escape belt and a high-altitude escape device. Summary of the Invention

[0004] One object of the present invention is to provide an escape belt, comprising:

[0005] Webbing with a skip section; and

[0006] The foot pedal includes a first cover and a second cover, the first cover entering the gap to open the gap, the second cover covering the first cover, and the non-gaps portion of the webbing penetrating the second cover.

[0007] Using the above technical solution, the webbing includes an even number of webbing units, which are divided into two groups. The webbing units in the two groups are stacked and fixed, and there is a gap between the webbing units in the two groups.

[0008] Using the above technical solution, each group has at least one webbing unit, and at least one webbing unit is stacked and fixed in pairs.

[0009] Using the above technical solution, the general structure of the first cover is arched, including a curved surface, and a boss that connects to the second cover is integrally formed on one side of the curved surface.

[0010] The above technical solution also includes a first anti-slip protrusion. The first cover includes a flat portion, and the first anti-slip protrusion is provided on the side of the flat portion facing the curved portion.

[0011] Using the above technical solution, the second cover includes a contoured cover and a protective plate. The contoured cover is provided with a contoured part that is adapted to the first cover, and the opposite side of the contoured part is provided with a through hole that is adapted to the webbing. The other end of the protective plate away from the contoured cover is integrally formed with a limiting part.

[0012] The above technical solution also includes a second anti-slip protrusion, which is provided on the protective plate.

[0013] Using the above technical solution, the contour cover and the protective plate are formed separately and then fixed together.

[0014] The above technical solution also includes a connecting part, which is connected to a webbing. The connecting part is provided with a connecting hole, which is configured to connect a fastener to fix the escape belt.

[0015] Another object of the present invention is to provide a high-altitude escape device, which includes the escape belt described above.

[0016] The beneficial effects of the present invention are as follows: The webbing of the present invention is provided with a jump-out part, and the foot pedal includes a first cover that opens the jump-out part, a second cover that covers the first cover, and the webbing passes through the second cover. This allows the connection between the webbing and the foot pedal to be achieved without damaging the webbing. On the one hand, it does not affect the load-bearing capacity of the escape belt, and on the other hand, the webbing is not easy to tear, making it safe to use, durable, and easy to promote.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Example 1

[0026] Reference Figures 1 to 4 As shown, Embodiment 1 of the present invention provides an escape belt, including a webbing 1 and a foot pedal 2. The webbing 1 is provided with a jump section 12. The foot pedal 2 includes a first cover and a second cover. The first cover enters the jump section 12 to open the jump section 12. The second cover covers the first cover, and the non-jump section 12 of the webbing 1 passes through the second cover, so that the connection between the webbing 1 and the foot pedal 2 can be achieved without damaging the webbing 1.

[0027] In this embodiment, the webbing 1 includes an even number of webbing units 11, which are divided into two groups. The webbing units 11 in the two groups are stacked and fixed, and there is a gap 12 between the webbing units 11 in the two groups. The number of webbing units 11 in each group is at least one, and at least one webbing unit 11 is stacked and fixed in pairs. In a preferred embodiment, the webbing 1 of the present invention includes two webbing units 11, which are stacked and fixed in pairs, and there are multiple gaps 12 between the two webbing units 11. The gaps 12 are used to connect the foot pedal 2. Of course, according to actual usage requirements, the webbing 1 can also be four webbing units 11, with each group including two webbing units 11, and the two webbing units 11 in each group are stacked and fixed to form an integral structure.

[0028] Furthermore, to reduce restrictions on height, the length of the webbing 1 in this invention can be increased indefinitely. For example, in the case of escaping from a high-rise building, assuming each floor is 3 meters high, when the floor height is 5, the length of the webbing 1 should be at least 12 meters. However, to allow for flexibility, the length of the webbing 1 can be 13 or 14 meters. When the floor height is 18, the length of the webbing 1 should be at least 51 meters, and the length of the webbing 1 can be 52 or 53 meters. When the floor height is 36, the length of the webbing 1 should be at least 105 meters, and the length of the webbing 1 can be 106 or 107 meters. Of course, this invention is not limited to these limitations and can also be applied to other high-altitude escape scenarios, such as helicopter descent. In this case, the length of the webbing 1 can be customized according to the actual situation.

[0029] In this embodiment, the general structure of the first cover is arched, including a curved surface 211 and a flat surface 212. A boss 2111 is integrally formed on one side of the curved surface 211. The second cover includes a contoured cover 221. The contoured cover 221 is provided with a contoured part that is adapted to the first cover, and the opposite side of the contoured part is provided with a through hole 2211 that is adapted to the webbing 1.

[0030] Of course, the first cover of this invention is set as an arched structure. Compared with other structures, the arch can withstand greater forces and is not easily damaged.

[0031] In summary, the connection method between the webbing 1 and the foot pedal 2 is as follows: First, the first cover is inserted into the gap 12 of the webbing 1, so that the inner side of the gap 12 abuts against the outer surface of the first cover, as shown below. Figure 4 As shown, the webbing 1 on both sides of the jump section 12 is then passed through the through hole 2211 through the contour cover 221 included in the second cover, so that the edge of the contour cover 221 abuts against the protrusion 2111 on the edge of the first cover 21, and then it is riveted and fixed. This connection method will not cause the webbing 1 to be damaged. On the one hand, it will not affect the load-bearing capacity of the escape belt, and on the other hand, the webbing 1 is not easy to tear, making it safe to use and durable.

[0032] Considering that when a person steps down during an escape, the footrest 2 will shift towards the wall. Since the wall temperature is high during a fire in a high-rise building, if a person's foot directly contacts the wall during the escape, it may cause burns. Therefore, based on this embodiment, the second cover of the present invention also includes a protective plate 222. The protective plate 222 is connected to the contour cover 221. The other end of the protective plate 222 away from the contour cover 221 is integrally formed with a limiting part 2221. The actual length of the protective plate 222 is definitely significantly greater than the length of a person's foot, which leaves a certain margin when a person steps down. In addition, the limiting part 2221 can effectively prevent the person's foot from directly contacting the wall, ensuring safe use.

[0033] Considering the possibility of slipping when stepping, in this embodiment, the present invention also includes a first anti-slip protrusion 3 and a second anti-slip protrusion 4. The first anti-slip protrusion 3 is provided on the side of the flat part 212 facing the curved part 211, and the second anti-slip protrusion 4 is provided on the protective plate 222, so that anti-slip protrusions are provided where the foot lands, which can have a better anti-slip effect.

[0034] Considering the difficulty of the molding process, in this embodiment, the contour cover 221 and the protective plate 222 are molded separately and then fixed together. For example, the contour cover 221 and the protective plate 222 are molded separately and then fixed together by welding.

[0035] In this embodiment, a connecting part 5 is also included. The connecting part 5 is connected to the webbing 1. The connecting part 5 is provided with a connecting hole, which is configured to connect a fastener (not shown in the figure) to fix the escape belt. The fastener can be any type of connecting part, such as a connecting ring, as long as it can fix the escape belt. This invention is not limited to this.

[0036] Considering safety issues, this invention needs to be used in conjunction with a protective device (not shown in the figure) in actual use. This can effectively reduce the level of fear and ensure the safety of the escapee. The protective device is a publicly available and widely used existing technology. Therefore, the specific structure of the protective device will not be described in detail in this invention.
