Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is used when escaping from a high place such as a building, and particularly relates to a small and conveniently portable escape device from a high place.

[Technical background of the invention and its problems] This type of escape device from a high place is a device that allows people who have jumped from a building to descend safely without colliding with the ground in the event of a building fire. Examples of the apparatus include those described in Japanese Utility Model Application Publication No. 53-161600 and Japanese Utility Model Application Publication No. 52-51200. In the case of the former, a steel cable is wound around the main body of the descending tool, and a seat and a brake section are attached to this descending tool.The outer diameter of the main body of the descending tool is approximately 100 mm, so it is difficult to carry it around at all times. Moreover, since the frictional resistance between the steel cable and the descending gear body is used as the descending braking force, there is a risk of falling due to damage to the steel cable, and due to the difference in the weight of the users, the appropriate braking force will not be applied naturally. Therefore, there was a problem with its reliability. In the latter case, the descending speed is controlled by the person escaping by regulating the rotation of the steel cable winding ring around which the steel cable is wound, via a handle and a stabilizing screw. The problem was that it was extremely large and could not be carried around at all times, and if the person who escaped lost the strength to escape, it would not only be impossible to descend, but the risk of crashing would be extremely high.

[Purpose of the invention] The present invention was created in view of the above circumstances, and its purpose is to be able to naturally obtain an appropriate descending speed despite the difference in the weight of the person escaping, and to carry the device at all times. It is an object of the present invention to provide an escape device from a height that can achieve miniaturization suitable for.

[Summary of the invention] In order to achieve the above object, the present invention includes a first frame, a disk pivotally supported by the first frame, and an arrangement substantially perpendicular to the rotational axis of the disk. A guide rod is fixed to the first frame, and a second frame is separated from the first frame.
a first brake lever having one end pivotally supported on the frame, an intermediate portion thereof contacting the upper end side circumference of the guide rod, extending downwardly at a predetermined inclination angle, and having a tip thereof contacting the lower end surface of the disc; a second brake lever having one end pivotally supported by the second frame, an intermediate portion thereof contacting the lower end side periphery of the guide rod, extending upwardly at a predetermined inclination angle, and having a tip thereof contacting the upper end surface of the disk; a belt whose one end is connected to the second frame; and whose tip is connected to the first frame;
a steel cable of a predetermined length protruding from the frame of the disc, an intermediate part of which is wound at least twice in a groove formed on the circumferential surface of the disc, and the remaining part of which is retractably accommodated in the belt; A force acting in the opposite direction to the force acting on the first frame through the steel cable wound around the belt is applied to the second frame through the belt, thereby causing the first and second brake levers to The guide rod bites into the upwardly extending portion and downwardly extending portion of the steel cable and applies force in the direction of expanding these portions, pressing both end faces of the disk and braking the rotation of the disk, thereby pulling out the steel cable. The speed is controlled.

[Embodiment of the invention] Fig. 1 is a partially cutaway perspective view showing an embodiment of the invention, and Fig. 2 is a sectional view of the same device. What is indicated by 1 in the figure is the first frame, for example, it has an opening 1A at the tip, a space is formed inside, and a pair of holding parts 2 and 3 are arranged facing each other in the middle part with the space in between. It has a gate-shaped structure.
Boss portions 2A,
A disk 4 is rotatably supported on the boss portions 2A and 3A, and both end surfaces are held and pressed by the flat surfaces of the holding portions 2 and 3 with a predetermined force. Note that this disk 4 has a groove 4A on its outer peripheral surface.
has. Further, a fitting hole 2B is formed in the boss portion 2A, and a screw 3B is implanted in the boss portion 3A, the tip of which projects into the fitting hole 2B. The reference numeral 5 in the figure is an adjustment lever that is screwed onto the screw 3B and loosely engaged with the fitting hole 2B so as to be freely rotatable. When the adjustment lever 5 is in the position shown in FIG. 1, the lever 5 is screwed onto the screw 3B.
As a result of being tightened down, the disk 4 is pressed and clamped by the end faces of both the holding parts 2 and 3, and as the lever 5 is rotated counterclockwise, the lever 5 screwed onto the screw 3B is tightened. As the holding parts 2 and 3 are loosened, the pressure and clamping of the disk 4 by the end faces of both the holding parts 2 and 3 is gradually relaxed, and eventually the clamping force can be released to the initially set clamping force. Furthermore, the first
A guide rod 6 is fixed to the frame 1 at a position perpendicular to the rotation axis of the disk 4.

In the figure, the frame indicated by 10 is a second frame separated from the first frame 1 described above. The second
The frame 10 has one end pivoted to the second frame 10 via a pin 12, an intermediate part that contacts the upper end side periphery of the guide rod 6, and extends downwardly at a predetermined angle of inclination. A first brake lever 11 is in contact with the lower end surface of the disc 4, and one end is pivotally supported on the second frame 10 via the pin 12, and the middle part is in contact with the lower end side periphery of the guide rod 6 at a predetermined inclination angle. A second brake lever 13 is provided which extends upwardly and has its tip end contacting the upper end surface of the disc 4.

One end of a belt 15 is connected to the rear end of the second frame 10. A space (not shown) is formed in this belt 15, and a steel cable 16 of a predetermined length is housed in the space so as to be freely drawn out.The base end of the steel cable 16 is connected to the second frame 10.
The intermediate portion is folded and accommodated in the space (not shown) in large numbers, and the portion drawn out from the belt 15 passes through the second brake lever 13 and is further formed on the circumferential surface of the disk 4. It is wound at least twice around the groove portion 4A, and its distal end protrudes to the distal end of the first frame through the opening 1A. Note that a hook 17 is coupled to the protruding tip.

The belt 15 is mainly made of webbing used for example as a safety belt for automobiles, and a steel cable 16 with many bends is placed on one surface thereof, and a film coating is applied thereon to accommodate the steel cable. An engaging protrusion 15A is formed at the other end (ie, self-curving end) of the belt 15. In order to removably connect the belt 15 to the second frame 10 via the engagement protrusion 15A, a locking lever 18 is rotatably supported on the second frame 10, and the locking lever 18 is A stopper 19 that can come into contact with the lever 18 is fixed to the second frame 10.

On the other hand, a suitable buckle 20 is attached to the lower surface of the first frame 1 so as to be fastened through a coupling hole 15B formed in the belt 15, and functions as a band for fastening clothes. It is also equipped with

Next, the operation of the apparatus of the above embodiment will be explained.

The device of the above embodiment can be carried around by using it as a band to fasten clothes, such as pants, during normal times. That is, belt 1

is pressed and fixed by the end surfaces of both the holding parts 2 and 3.

Next, we will explain the action during emergency evacuation. First, the adjusting lever 5 shown in FIG. For example, the disk 4 is allowed to rotate with the initial tension of about 7 to 8 kg, and the steel cable 16 can be pulled out.

Then, a hook 17 fixed to the tip of the steel cable 16 is fixed to a balcony of a building, indoor furniture, or the like. Thereafter, the belt 15 is moved along the arrow B ₁ shown in FIG.
B It is bent in _two directions, wrapped around the wearer's (escapee's) torso, and its tip is fixed to the second frame 10 via the locking lever 18. When fixing, the locking lever 18 may be rotated in the direction of the first arrow C shown in the figure, and then the tip of the belt 15 may be inserted between the second frame 10 and the locking lever 18. In this way, the engagement protrusion 15A of the belt 15 can be attached to the locking lever 1.
8, and the locking lever 18 is restrained by the stopper 1.
As a result of the rotation being restricted at 9, the second frame 10
You will never get out of it.

When the embodiment device is attached to the escaper H as described above, the escaper H will jump from a high place. The state at that time is as shown in FIG.

If you jump down in this way, the above disk 4
A tension in the E direction shown in FIG. 2 is applied to the first frame 1 through the steel cable 16 wound around the steel cable 16 . Further, a tension in the direction of a second arrow F (opposite to the direction E) proportional to the weight of the escapee H is applied to the second frame 10 via the belt 15. If we consider the sizes of both tensions above, the tension in the direction of arrow E will eventually become the escaper H.
Moreover, since the first frame 1 and the second frame 10 are separated, the tension in the direction of the arrow F acting on the second frame 10 is greater. Therefore, the second frame 10 is subjected to a force in a direction that moves it away from the first frame 1. Therefore, due to such relative displacement of the frames 1 and 10 in the separating direction, the guide rod 6 bites into the upwardly extending portion and the downwardly extending portion of both the brake levers 11 and 13, and a force is applied in the direction of expanding both portions. The tips of the brake levers 11 and 13 press both end surfaces of the disc 4 to brake the rotation of the disc 4. This braking force restricts the rotation of the disk 4 and controls the speed at which the steel cable is pulled out via the disk 4, allowing the escapee H to gradually descend, for example, about 40 meters per minute, and safely reach the ground.

As is clear from the detailed explanation above, since the tension applied to the second frame 10 is proportional to the weight of the escapee, the braking force applied to the disc 4 via both brake levers 11 and 13 is also proportional to the weight of the escapee. It is proportional to the weight of the person escaping, so the appropriate braking force is automatically applied regardless of the weight of the person escaping, allowing the person to descend at an appropriate and safe speed at all times. Furthermore, since the above-mentioned braking force is not obtained by the escaper's operation, it is possible to reliably prevent the escaper from losing his strength and falling, which is the case with conventional devices. Note that it is possible to finely adjust the descending speed by operating the adjustment lever 5. Also, both brake levers 1
Fine adjustment of the braking force is also possible by pinching and pressing the tips of 1 and 13 between fingers. Furthermore, since this device is small and always portable as a band, it can be carried by each person and is fully effective as a preparation for accidental accidents such as building fires. can also contribute to society.

It goes without saying that the above-mentioned embodiment is merely an example, and that various modifications can be made within the scope of the gist of the present invention.

For example, the present device is not limited to a structure that can also be used as a band, and therefore a buckle or the like can be eliminated. In this way, the device can be carried in a bag, pocket, etc., and the same effects as the device of the embodiment can be obtained. Further, it is not necessary to provide an adjustment lever. This is because the braking force can be finely adjusted by pinching the tips of both brake levers 11 and 13 between fingers, and furthermore, both end surfaces of the disc 4 can be adjusted to a predetermined level by the flat surfaces of the holding parts 2 and 3. This is because the steel cables will not be pulled out when being carried because they are pressed and clamped with force.

[Effects of the invention] As detailed above, the device for escaping from a high place of the present invention can automatically obtain an appropriate descending speed regardless of the difference in the weight of the person escaping, and is suitable for being carried at all times. This has effects such as being able to achieve miniaturization.
