Abstract

The sliding escape ladder for a downward escape route according to the present invention is an escape ladder installed in a downward escape route of an apartment, comprising: an upper cover formed to be openable and closable on the floor of an upper floor; an escape route connecting an upper floor and a lower floor, forming a space below the upper cover; a lower cover formed to be openable and closable at the bottom of the escape route and forming the ceiling of the lower floor; and a ladder part stored in close contact with the wall of the upper floor and slidingly unfolded to the lower floor through the escape route so that an evacuee from the upper floor can move to the lower floor, thereby having the effect of rapidly unfolding the ladder to the lower floor.

  1. As an escape ladder installed in a downward-facing escape hatch of an apartment, An upper cover formed to be openable and closable on the floor of the upper layer; An escape opening forming a space below the upper cover and connecting the upper and lower layers; A lower cover formed at the bottom of the above-mentioned escape opening so as to be openable and closable, and forming the ceiling of the lower floor; and It includes a ladder section that is stored in close contact with the wall of the upper floor and slides out to the lower floor through the escape opening so that evacuees from the upper floor can move to the lower floor, The above ladder section is, A pair of guide frames fixed to the wall of the upper layer and having a groove formed on one side; A ladder fixed and stored between the above pair of guide frames, and when released, unfolds toward the escape route and slides to the lower floor; and Includes a connecting member that connects the ladder and the pair of guide frames, and unfolds and slides the ladder through vertical rotation and up-and-down movement. The above ladder section is, It further includes an auxiliary guide formed as a 'ㄷ'-shaped frame and fixed to the lower floor wall so as to protrude below the escape route, The above ladder slides to the lower floor while passing through the internal space of the above 'U'-shaped auxiliary guide, thereby preventing the ladder from shaking in the direction of the escape route during evacuation, and The above lower cover is, One side of the escape route and the wall at the top of the escape route are connected by a wire, and in the event of a fire, when the wire is released, the lower cover opens. The above ladder section is, A sliding escape ladder for a downward escape route, characterized by further including a ladder cover fixed to an upper floor wall while surrounding the front of the ladder.

  3. In paragraph 1, The above connecting member is, A sliding link inserted into a groove of the guide frame and moving up and down along the groove; and A sliding escape ladder for a downward escape route comprising a pivot link, one end of which is connected to the sliding link and the other end of which is connected to the ladder and rotates in a vertical direction.
  4. In paragraph 1, The above ladder section is, A sliding escape ladder for a downward escape route, characterized by further including a fixing pin that penetrates the side of the guide frame and the side of the ladder so that the ladder is fixed to the upper floor.

Description

Sliding escape ladder for top-down evacuation area The present invention relates to a sliding type escape ladder applicable to downward escape hatches of high-rise buildings. In emergency situations such as fires, rapid evacuation is a critical factor in protecting lives. Particularly in high-rise buildings like apartments, securing evacuation routes is essential, and various evacuation systems and devices are provided. Generally, emergency exits, evacuation balconies, fire doors, and descent devices are installed, and in some cases, elevator-type or foldable escape ladders are also installed. Downward-facing escape routes are firefighting facilities installed in locations such as balconies, designed to allow evacuation from upper floors to lower floors. While this system offers the advantage of providing an effective evacuation route even in confined spaces, improvements are needed in terms of convenience and safety compared to existing escape ladders. Conventional downward-facing escape ladders were often foldable and stored within the escape route. In such cases, evacuees had to deploy the stored ladder by directly operating a device or manually extending it. However, these retractable ladders often caused difficulties in evacuation because evacuees in a state of panic during an emergency found it difficult to quickly figure out how to deploy them. Furthermore, conventional folding ladders as described above had the problem of shaking during actual use because they were not completely fixed when unfolded. This presented safety issues as well as a sense of fear for users, making evacuation more difficult for young children.
