Description

desk safety ladder

An embodiment of the present invention relates to a ladder.

In general, a studio or gosiwon is vulnerable to fire because several rooms are attached to a narrow space. Moreover, in the event of a fire, in many cases, means for suppressing the fire or means for evacuation are not properly provided. As a result, many casualties occur in case of fire. Therefore, there is a need for a method to safely evacuate when a fire occurs in a residential facility such as a studio or a gosiwon.

Here, since the lower frame 111 is located on the inner surface of the building wall, and the second support frame 119 is seated on the lower window frame, the desk-type safety ladder 100 can be stably supported by the lower window frame.

Here, the ladder part 123 of the ladder unit 104 is shown as seven. The desk plate 115 may be combined with the innermost ladder part 123-7. Since the desk plate 115 is in a coupled state with the ladder unit 104 , the ladder portion of the ladder unit 104 is sequentially deployed and unfolded by the weight of the desk plate 115 .

12 shows a state in which the first ladder part 123-1 is deployed, the desk plate 115 except for the first ladder part 123-1 and the remaining ladder parts are a first pair of guide parts 125- It slides along 1) and descends. Here, the first binding part 129-1 provided at one end of the first pair of guide parts 125-1 is the second binding part 129-2 of the second pair of guide parts 125-2. ) and the deployment of the first ladder part 123-1 is completed while binding.

13 shows a state in which the second ladder part 123-1 is deployed, except for the first ladder part 123-1 and the second ladder part 123-2, the desk plate 115 and the remaining ladder parts It descends while sliding along the second pair of guide parts 125-2. Here, the first binding part 129-1 provided at one end of the second pair of guide parts 125-2 is the second binding part 129-2 of the third pair of guide parts 125-3. ) and the deployment of the second ladder part 123-2 is completed while being bound.

In this way, all of the remaining ladders are also deployed, and in FIG. 14 , each of the ladders 123-1 to 123-7 of the ladder unit 104 is shown in a fully deployed state.

Here, the user may step down on the footrest of each ladder unit (123-1 ~ 123-7). At this time, since the footrest unit 127 is in a folded state in the ladder unit 104, as shown in FIG. 15, as the footrest unit 127 is rotated clockwise to unfold, the user can easily use the footrest unit 127. can make it possible to step on

According to the disclosed embodiment, through the desk-type safety ladder 100 having the desk unit 102 and the ladder unit 104, it is usually used as a desk, but in an emergency such as a fire, it can be used as a ladder to evacuate. there will be In addition, since there is no need for a separate evacuation device, it is possible to increase the space utilization of a narrow space such as a studio, and to increase the safety evacuation in case of an emergency.

16 is a diagram schematically showing a desk-type safety ladder according to another embodiment of the present invention.

Referring to FIG. 16 , the desk-type safety ladder 100 may further include a safety rope 106 , a stiffener 108 , and a seat belt 110 .

The safety rope 106 may have one end connected to the upper frame 113 . In an exemplary embodiment, the safety rope 106 may be connected to the safety pin hole 121 . The safety rope 106 may be provided through the stiffener 108 .

The stiffener 108 is a mechanism that presses the safety rope 106 so that the user can slowly descend on the desk-type safety ladder 100 . Since the wanganggi 108 is a known device, a detailed description thereof will be omitted. The bracing machine 108 may be housed within the ladder unit 104 . In an exemplary embodiment, the armband 108 may be accommodated between a pair of guide portions of the ladder portion located at the innermost side.

The seat belt 110 may be connected to the brace 108 . The seat belt 110 is used by the user on the waist, etc., and may serve to support the user's body when descending through the desk-type safety ladder 100 . The seat belt 110 may be accommodated in the ladder unit 104 . In an exemplary embodiment, the seat belt 110 may be accommodated on an area with a footrest between the desk plate 115 and the ladder unit 104 .

In this way, as the desk-type safety ladder 100 is provided with the safety rope 106, the stiffener 108, and the seat belt 110, the safety of the user when the user evacuates through the desk-type safety ladder 100 can be raised even higher.

Although representative embodiments of the present invention have been described in detail above, those of ordinary skill in the art to which the present invention pertains will understand that various modifications are possible within the limits without departing from the scope of the present invention with respect to the above-described embodiments. . Therefore, the scope of the present invention should not be limited to the described embodiments and should be defined by the claims described below as well as the claims and equivalents.
