Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is an improvement of a slow-moving machine that is installed mainly in high places such as buildings and condominiums, and that allows evacuees to safely descend and evacuate from high places to the ground during an emergency evacuation such as a fire. Regarding

[0002]

[Prior art]

 Generally, as this kind of slow-down machine, the structure shown in FIG. 9 has been widely used for a long time. That is, the slow down gear includes a speed governor 40 including a pulley, a planetary gear and a centrifugal brake, a hook 41 provided on the speed governor 40, and a rope 42 suspended and supported by the speed governor 40 pulley. And a ring-shaped belt 43 attached to both ends of the rope 42, an adjusting ring 44 attached to the belt 43 to adjust the length of the belt 43, a reel 45 for winding the rope 42, and the like.

When evacuating using the slow landing gear, first, the speed governor 40 is attached to a fitting (not shown) fixed to the veranda or roof of the building via the hook 41. Hang it down. Next, after confirming the safety of the descent point, the reel 45 around which the rope 42 is wound is thrown down to the ground to bring the rope 42 into a suspended state. After the rope 42 is suspended, the evacuee puts the belt 43 on the armpit and tightens the belt 43 with the adjusting ring 44. After that, the evacuee grasps the two hanging ropes 42 (the portion located near the governor 40) together, goes out from the balcony or the like to the outside of the building, and hangs it. Then, when the evacuee hangs completely on the rope 42, he / she releases the two ropes 42 he is holding. Then, the rope 42 gently descends due to the action of the speed governor 40, and the evacuee can land on the ground without being shocked. In particular, this slow-moving machine is of a slip type in which belts 43 are attached to both ends of the rope 42, so that when one person descends, the other belt 43 rises and the next evacuee descends with this belt 43. It is now possible to improve the evacuation efficiency.

[0004]

[Problems to be solved by the device]

 However, since the slow-moving machine has a structure in which a ring-shaped belt 43 is attached to the armpit of the evacuee, it may fall out of the belt 43 when the evacuee is in a state of evacuation. There was an extremely problem. Further, even if the belt 43 is sufficiently tightened by the adjusting ring 44 provided on the belt 43, there is a problem that the belt 43 loosens during the descent and the body slips out. In particular, in an emergency evacuation such as a fire, the evacuee may be in a hurry to forget to tighten the adjusting ring 44 of the belt 43, which further aggravates the above problem. Further, when the belt 43 is worn on the armpit, there is a problem that the belt 43 bites into the armpit when the evacuee hangs, causing pain and damage to the evacuee. However, since the evacuees will be suspended during descent, it will give them considerable fear. As a result, evacuees sometimes hesitated to descend and it took an extremely long time to evacuate.

On the other hand, instead of the side-hanging type belt 43, a slow-moving machine in which a crotch-hanging type belt 43 is attached to both ends of the rope 42 is also used. Since this slow-moving machine has a structure in which the belt 43 is attached to the crotch of the body and other parts (armpits and shoulders), there is an advantage that the body can be prevented from falling out of the belt 43. However, since the belt 43 is divided into a number of belts, this slowdown machine has a problem that it cannot be used effectively because the way of wearing it on the body is unknown. In particular, if the evacuees are young or old, the above problems will become more prominent.

The present invention was devised in order to solve the above-mentioned problems, and its purpose is to provide excellent safety and handling, and to be able to descend without causing pain or fear. It is to provide a slowdown.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the slow-moving machine of the present invention is suspended and supported by a fixed member provided at a high place such as a building, and a speed governor for adjusting the feeding speed of the rope and both ends of the speed governor. The rope is suspended and supported in a suspended state, and is connected to both ends or one end of the rope in a suspended state with a rope of an appropriate length that moves slowly due to the action of the governor when the load of the evacuee is applied. , An evacuation storage bag with an open top that can accommodate evacuees. In addition, it is preferable that the speed governor be provided with a stopper mechanism that prevents the line from moving out. Further, the evacuation storage bag is preferably configured to be foldable or extendable in the vertical direction.

[0008]

[Action]

 When evacuating using the slow down gear, the speed governor is suspended via hooks or the like from a fixing member installed on the veranda or the like of the building. After suspending the governor on the fixed member, check the safety of the descent point, then drop the rope and one of the evacuation storage bags from the veranda etc. to put the rope in a hanging state and evacuate the other. Put the storage bag out of the building and extend it. Once the evacuation bag is in the extended state, the evacuees board the evacuation bag located outside the balcony. At this time, if the speed governor is locked by the stopper mechanism, the extension of the rope is prevented, and even if the evacuee gets into the evacuation storage bag, the evacuation storage bag does not fall without permission. The person does not feel fear. The evacuee then operates the stopper mechanism provided on the governor to release the locked state of the governor. Then, the rope gradually descends due to the action of the governor, and along with this, the evacuation storage bag also descends at a low speed, allowing the evacuees to descend and evacuate while riding on the evacuation storage bag. . At this time, the evacuees are in the evacuation bag, so they are not likely to fall during the descent, and are extremely safe. Evacuees can also descend without feeling anxiety or physical distress. When the evacuation bag arrives, the evacuee shortens the bag and goes out of the bag to quickly evacuate to a safe place. At this time, since the accommodation bag can be shortened, the evacuee can quickly and easily exit the accommodation bag.

When it is not in use, it is shortened and is covered with a waterproof box (not shown) or sheet (not shown) as in the slow-down machine.

The speed governor 1 is suspended and supported by a fixing member (mounting metal fitting 5 in this embodiment) provided at a high place such as a building, and adjusts the feeding speed of the rope 3. In the example, the governor 1 has the structure disclosed in Japanese Utility Model Publication No. 2-28928. That is, as shown in FIGS. 3 to 6, the speed governor 1 includes a closed container 10, a rotary shaft 11, a stirring blade 12, a large number of balls 13, a grease 14, a pulley 15, and a stopper mechanism 16. And the guide tube 17 and the like. Specifically, the closed container 10 is composed of a cylindrical main body 18 having an opening 26 at its end, and side plates 19 that hermetically close both ends of the main body 18, and a sheet packing 20 is attached to the inner surface thereof. Has been done. On the outer peripheral surface of the main body 18 of the closed container 10, a hook 2 having a substantially inverted U shape is fixed to the arm 9 of the mounting bracket 5 so as not to rotate, and the speed governor 1 is suspended and fixed to the arm 9. Has been done. In this embodiment, the inner diameter of the main body 18 is set to about 80 mm, and the distance between the side plates 19 is set to about 85 mm. The rotating shaft 11 is inserted into the axial center position of the closed container 10, and is supported by both side plates 19 via bearing metal 21 so as to be rotatable and immovable in the axial direction. A cylindrical body 22 is externally fitted and fixed to the rotary shaft 11, and a plurality of stirring blades 12 are fixed to the cylindrical body 22. In the present embodiment, the stirring blades 12 have a substantially fan shape, and as shown in FIGS. 3 and 4, the four stirring blades 12 are symmetrically arranged and are arranged around the cylindrical body 22. It is fixed to the outer peripheral surface of the cylindrical body 22 in a state of being inclined at 45 degrees with respect to. A large number of balls 13 and grease 14 are stored in the closed container 10. In this embodiment, steel balls are used as the balls 13, and approximately 3000 steel balls having a diameter of 4 mm and approximately 1000 steel balls having a diameter of 3 mm are stored in the closed container 10. Silicon grease 14 having excellent heat resistance is used as the grease 14, and about 130 g of the grease is injected into the closed container 10. The pulley 15 is made of a plastic material, and is fixed to one end of the rotary shaft 11 at an outer position of the side plate 19, and triangular teeth are formed on the outer peripheral surface thereof. Around the pulley 15, a single plastic guide roller 24 having triangular teeth formed on the outer peripheral surface and a plurality of plastic guide rollers 25 having annular grooves formed on the outer peripheral surface are arranged. These rollers 24 and 25 are good guides for the rope 3 suspended on the pulley 15. The former guide roller 24 is rotatably supported by the shaft 27 on the side plate 19 in the vicinity of the opening 26 of the main body 18, and the latter guide roller 25 is loosely fitted and fixed to the end of the rotary shaft 11. It is prevented from coming off by a circular disc 28. The stopper mechanism 16 blocks the rotation of the rotary shaft 11 to stop the feeding of the rope 3 described later, and is a claw fitted to the other end of the rotary shaft 11 at the outer position of the side plate 19. An engaging position (a solid line position in FIG. 6) engaged with the ratchet wheel 29 and a disengaged position (see FIG. A pair of claw bodies 30 that can take the position indicated by the alternate long and short dash line), a compression coil spring 31 that is interposed between the claw bodies 30 and the side plate 19, and urges the claw body 30 to swing to the engaging position, and the side plate 19. And an operating lever 33 provided with a cam body 32 which is pivotally supported so as to be swingable and which is located between the claw bodies 30 and swings each claw body 30. The shape of the cam body 32 is such that when the operating lever 33 is set to the lock position (solid line position in FIG. 6), the claw bodies 30 are urged to the engaging position and the operating lever 33 is set to the unlocked position. When set to the position indicated by the alternate long and short dash line in FIG. 6, it is set so that each claw body 30 is moved to the disengaged position against the compression coil spring 31. Therefore, when the operation lever 33 is set to the lock position, each of the claw bodies 30 is returned to the engagement position to prevent forward and reverse rotation of the rotary shaft 11, and when the operation lever 33 is set to the unlocked position. The one claw body 30 is brought to the disengaged position, and the rotary shaft 11 rotates only in one direction. The guide tube 17 keeps the distance between the two ropes 3 hanging down from the pulley 15 at a constant distance, and when the evacuation storage bags 4 (described later) connected to both ends of the ropes 3 pass each other, the storage bags 4 are This is to prevent collision. In this embodiment, the guide tube 17 has a bifurcated shape and is welded to the vicinity of the opening 26 of the closed container 10, and a guide roller 34 for guiding the cord 3 is rotatably supported therein. .

The cord 3 is suspended on the pulley 15 of the speed governor 1 with both ends hanging down. In this embodiment, the cord 3 is made of a wire rope made of cotton thread, synthetic fiber, hemp, or the like. The coated one is used. The length of the rope 3 is set so as to be slightly longer than the distance from the installation location of the slow dismounter to the ground.

The evacuation storage bag 4 is made of a material having excellent flexibility, strength, etc. and is configured to be foldable or extendable in the vertical direction. In the present embodiment, it is configured to be extendable in the vertical direction. Has been done. Specifically, as shown in FIGS. 7 and 8, the evacuation storage bag 4 is formed into a bottomed tubular shape whose upper side is opened by a cloth such as a duck whose surface is coated with a fireproofing agent. It has a bellows structure so that it can be easily stretched up and down. Further, an annular support frame 35 made of metal or plastic and a rectangular step cloth 36 made of cloth are attached to the upper end of the evacuation storage bag 4, respectively. The support frame 35 prevents the evacuation storage bag 4 from losing its shape, and the step cloth 36 is hung on the handrail portion of the veranda so that the evacuee can easily transfer to the storage bag 4. . Further, a light-weight floor plate 37 is attached to the bottom of the evacuation storage bag 4 so that the evacuation person does not lose its shape when riding on the floor plate 37 and the bottom of the evacuation storage bag 4. A cushioning material 38 such as a sponge is interposed between the two to soften the impact at the time of landing. The evacuation storage bag 4 is connected to both ends of the rope 3 in a suspended state via a plurality of ropes 39 (or belts). The evacuation storage bag 4 is formed so that at least the lower body of the evacuee can be accommodated therein. In this embodiment, the evacuation storage bag 4 has a diameter of about 50 cm and a height when extended. Each is set to be 90 cm.

Next, a case of evacuating using the slow-down machine will be described. When not in use, the slow down gear is stored in a storage box 6 installed on the veranda. At this time, the evacuation storage bag 4 is, of course, stored in a shortened state. In an emergency evacuation such as a fire, first, the mounting member 5 is extended as shown in FIGS. 1 and 2, and the arm 9 is projected to the outside of the veranda. Next, the slow down gear is taken out from the storage box 6, the hook 2 of the speed governor 1 is externally fitted to the arm 9, and the retaining pin 8 is inserted through the hook 2 and the arm 9 to arm the speed governor 1. Stop coming out of 9. At this time, the speed governor 1 is locked by the stopper mechanism 16. After suspending the speed governor 1 on the arm 9, after confirming the safety of the descent point, the rope 3 and one of the evacuation storage bags 4 are dropped from the veranda and the rope 3 is suspended. , The other evacuation storage bag 4 is taken out of the balcony to be in an extended state. Then, the evacuee hangs the foot cloth 36 of the evacuation storage bag 4 located outside the veranda on the handrail part of the veranda, and steps into the evacuation storage bag 4 while stepping on the foot cloth 36. At this time, the evacuee gets into the evacuation storage bag 4 while stepping on the step cloth 36, so that the hanging evacuation storage bag 4 is prevented from swaying, and the evacuation storage bag 4 does not feel fear. It is safe and easy to get on board. In addition, since the speed governor 1 is locked by the stopper mechanism 16, even if an evacuee gets into the evacuation storage bag 4, the evacuation storage bag 4 does not fall without permission, and the evacuee feels fear. Never remember. After getting into the evacuation storage bag 4, the evacuee operates the stopper mechanism 16 so that the rope 3 is extended from the speed governor 1, and unlocks the speed governor 1. Then, the rope 3 on which the evacuee's load is applied gently descends due to the action of the governor 1, and the evacuation storage bag 4 also descends at a low speed accordingly. That is, when the locked state of the speed governor 1 is released, the rope 3 is paid out from the speed governor 1 by the load of the evacuees and the evacuation storage bag 4 and the pulley 15 and the rotating shaft 11 are rotated. . At this time, the rotary shaft 11 and the pulley 15 are rotated at a low speed from the start of rotation because the stirring blade 12 provided on the rotary shaft 11 is immediately subjected to resistance by the balls 13 and the grease 14. As a result, the rope 3 is gradually fed out from the beginning, and the evacuation storage bag 4 is lowered at a low speed from the beginning of the descent. Further, since the triangular teeth are formed on the outer peripheral surface of the pulley 15, the pulley 15 can be surely rotated when the rope 3 is paid out from the speed governor 1. As a result, the rotating shaft 11 also rotates reliably, and braking works reliably. It should be noted that this slow-moving machine does not mean that the evacuees fall during the descent because the evacuees are riding in the evacuation storage bag 4 at the time of the descent. Also, the evacuees do not feel uncomfortable or feel any physical pain during the descent. Then, as the evacuation storage bag 4 descends in sequence, the other evacuation storage bag 4 rises and both storage bags 4 cross each other on the way, but the rope 3 is kept at a certain distance by the guide tube 17. Since the storage bags 4 are kept, it is possible to prevent the storage bags 4 from colliding with each other when they cross each other, so that the two storage bags 4 for evacuation can be lowered or moved up smoothly. When the evacuation storage bag 4 lands, the evacuee shortens the storage bag 4 and exits the storage bag 4 to quickly evacuate to a safe place. At this time, since the accommodation bag 4 can be shortened, the evacuee can quickly and easily get out of the accommodation bag 4. Further, since the accommodating bag 4 is provided with the cushioning material 38 at the bottom, it does not receive a large shock when landing. In addition, since this slow-moving machine is a slipper type in which the evacuation storage bags 4 are connected to both ends of the rope 3, when one person descends, the other evacuation storage bag 4 rises and The bag 4 allows the subsequent evacuees to descend, improving the efficiency of evacuation.
