[Detailed Description of the Invention] This invention relates to an evacuation device that is installed on a mounting base such as the floor of a building and is used for safely escaping evacuees in the event of an emergency such as a fire.

This type of evacuation device includes, for example, a storage frame that is inserted and fixed into a hole made in the mounting base of a building, and the upper end is rotatably attached to the inside of the storage frame, and when not in use, it is inside the storage frame. an extensible evacuation device that is stored in a substantially horizontal manner and rotates downward to extend and descend when in use; one end is connected to the storage frame, the other end is connected to the evacuation device, and the device rotates downward Some have a locking rope that holds the moved evacuation equipment in a slightly inwardly inclined state.

Such an evacuation device holds the evacuation device, which rotates downward during use, at a predetermined angle of inclination using a locking rope, and forms an evacuation path that extends diagonally downward. It has the characteristics of low rocking, making it easier for evacuees to take up and down positions, making it easier for evacuees to go up and down, allowing quick evacuation, and high safety with less risk of falling. We are prepared.

However, although such evacuation devices have the above-mentioned features, when the evacuation equipment with tensioned latching ropes is in use, and when the evacuation equipment with relaxed latching ropes is not in use, the latching ropes do not close to the storage frame. The direction changes drastically at the connection part where it is connected to the evacuation equipment,
When the mooring rope is loosened when not in use, a portion of the mooring rope may hang downward in a loop shape from the evacuation equipment stored approximately horizontally within the storage frame, and may catch or become entangled with the evacuation equipment's treads, etc. There is a risk that the evacuation equipment may not operate smoothly during use.

The present invention has been devised in view of this point of view, and is provided with a connecting part restrictor that covers the connecting part of the locking rope and gives a predetermined directionality to the locking rope. When storing the evacuation equipment from a used state to an unused state, the mooring cable is guided to a position where it will not get caught or tangled with the evacuation equipment, and prevent smooth operation of the evacuation equipment when in use. To provide a building evacuation device that can prevent buildings from being damaged.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

1 to 5, a building evacuation system according to an embodiment of the present invention is shown. This evacuation device includes a storage frame 3 that is inserted and fixed into a hole 2 made in a mounting base 1 on the floor of a building, etc., and an upper end that is rotatable through a support shaft 13 inside the storage frame 3. When not in use, it is stored in the storage frame 3 in a substantially horizontal manner as shown in FIG. 1, and when in use, it rotates downward and extends downward as shown in FIG. 5. 4, one end is connected to the storage frame 3, the other end is connected to the evacuation device 4, and when in use, the evacuation device 4 is rotated downward.The evacuation device is tensioned linearly between the storage frame 3 and the storage frame 3. The storage frame 3 is held by holding the device 4 in a slightly inwardly inclined state, and loosens and deforms when not in use.
Deformable locking rope 5 such as a wire stored inside
and a connecting portion restricting device 6 attached to the connecting portion of the locking rope 5 with the evacuation device 4, formed in a cylindrical shape with an open upper end, covering the connecting portion and imparting upward directionality to the locking rope 5. It is made up of.

The connecting portion between the locking rope 5 and the evacuation device 4 is formed by passing the annular portion 8 formed at one end of the locking rope 5 through the head of an eyeball bolt 7 fixed to the evacuation device 4 and connecting them to each other. has been carried out, and also
The connecting portion regulating device 6 is attached to the evacuation device 4 side by an eye bolt 7 passing through the bottom thereof, and accommodates the head of the eye bolt 7 and the annular portion 8 of the locking rope 5 in its cylindrical portion, By restricting the range in which the annular portion 8 of the locking cable 5 rotates along the head of the eye bolt 7, a predetermined directionality is imparted to the locking cable 5.

In this embodiment, the storage frame 3 is provided with a lifting arm 9 made of an elastic material and having a retaining ring 10 at its free end, through which the locking cable 5 freely passes.
This pulling arm 9 is located above the evacuation device 4 when the evacuation device 4 is stored in the storage frame 3, and lifts up a substantially middle portion of the locking rope 5, and also lifts the evacuation device 4 upward. When the evacuation device 4 rotates downward and is held at a predetermined inclination angle, the evacuation device 4 is pulled by the tensioned locking rope 5 and bends its arm downward along the locking rope 5. When storing, a force for pulling up the locking rope 5 is exerted based on the repulsive force of the curved lifting arm 9 against the loosening locking rope 5.

Further, in this embodiment, the evacuation device 4 has a plurality of hollow sliding rods 11 connected to each other in a telescoping manner so as to be extendable and retractable, and the lower end of each sliding rod 11 has a wall extending toward both sides thereof. Although it is provided with a protruding step board 12, it is not limited to this,
For example, instead of making the sliding rod hollow, the sliding rod may have a channel shape, and instead of protruding from both sides of the lower end of the sliding rod 11, the tread plates 12 may be provided alternately from one side of the sliding rod 11. A folding ladder may also be used as shown in .

Furthermore, reference numerals 14 and 15 in the figure are an upper lid and a lower lid that close the upper and lower parts of the storage frame 3 that is inserted and fixed into the hole 2 of the mounting base 1, and these upper and lower lids 14,
15 are connected to each other by a link mechanism 16, so that when either one is opened or closed, the other is also opened or closed in conjunction.

Therefore, according to the evacuation device of this embodiment, when the upper cover 14 is opened, the lower cover 15 is also opened, and this lower cover 15 is opened.
The evacuation device 4 supported by the evacuation device 4 is rotated downward by its own weight, held at a predetermined inclination angle by the locking cable 5, and the sliding rod 11 is slid downward to extend and lower.

Next, in order to store the evacuation equipment 4 in the storage frame 3, first, each sliding rod 11 of the evacuation equipment 4 is contracted by means such as winding up, and rotated around the support shaft 13, and the storage frame 3 is and close the upper and lower lids 14 and 15.

As the evacuation device 4 is rotated upward, the locking cable 5 is relaxed and deformed, but the curved lifting arm 9 first pulls the locking cable 5 upward due to its repulsive force, and then the evacuation begins. When the appliance 4 reaches the approximately horizontal position in which it is stored, a connecting part regulating device 6 is installed to cover the connecting part between the evacuation appliance 4 and the locking rope 5.
This prevents the annular portion 8 of the locking rope 5 from turning around and falling off along the head of the eyeball bolt 7, and gives the vicinity of the annular portion 8 of the locking rope 5 an upward direction to the evacuation device 4. This prevents the locking rope 5 from forming a loop and hanging downward from the evacuation device 4, as shown by the imaginary line in FIG. 3, for example.

Next, FIGS. 6 to 9 show other embodiments of the connecting portion restricting device 6, and the connecting portion restricting device 6 in FIGS. 6 and 7 is formed in a coil shape from an elastic material, The inner diameter of the connecting portion restrictor 6 is formed to be approximately the same size as the head of the eye bolt 7, so that it is fitted onto the head of the eye bolt 7 by utilizing elasticity. The connecting portion restrictor 6 shown in FIGS. 8 and 9 is made by bending an elastic plate material into a substantially pentagonal shape, forming an elongated insertion hole 17 at the bottom into which the head of the eye bolt 7 is inserted, and having both ends The parts are brought close to each other to form a clamping part 18 for clamping the locking cable 5, and the head of the eye bolt 7 is inserted through the insertion hole 17 and rotated 90 degrees, so that the clamping part 18 is formed above the head of the eye bolt 7. 1
8, it is attached so as to sandwich the locking rope 5.

Further, in FIG. 10, unlike the above embodiments, the storage frame 3 and the evacuation equipment 4 are connected by a pair of locking ropes 5 formed of chains, and when in use, these pair of locking ropes 5 are connected. The evacuation device 4 is suspended by the connecting portion regulating device 6, which is connected to each of the locking ropes 5 and the storage frame 3.
The directionality of the connecting ring 19 located at the top of each locking rope 5 is controlled by covering the connecting part between the As the connecting ring 19 moves around along the center bolt 7 attached to the storage frame 3 forming the storage frame 3, each of the locking ropes 5 formed of chains is stored irregularly and does not get entangled with the evacuation equipment 4. There is no possibility that the chain rings constituting each of the locking ropes 5 will not stretch smoothly during use. In addition, in this embodiment, the evacuation device 4 is different from the evacuation devices shown in the above-mentioned embodiments, and is a folding device formed by connecting both ends of a large number of tread members 20 so as to be expandable and contractible with a connecting member not shown. It uses a formal ladder. Further, reference numeral 21 in the figure is a gripping rod on which to hold the hand when going up and down during use.

As mentioned above, in the building evacuation device of this invention, the locking cable that connects the storage frame and the evacuation equipment that is reduced and stored in the storage frame has a connecting part that is covered with the connecting part. A connecting part regulating device is provided that gives a predetermined directionality to the mooring rope, and this prevents the deformed mooring rope from becoming entangled with the evacuation device when the evacuation device is stored from the used state to the unused state. This prevents the evacuation equipment from getting caught, prevents the smooth operation of the evacuation equipment during use, and prevents evacuees from touching the connecting part of the evacuation rope when using it. There is no risk of injury from inserting or pinching the device.
