[Industrial application field]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable slow-lowering machine used for lowering human bodies from buildings or the like in the event of a fire.

[Conventional technology]

Conventional slow descent machines have a speed governor attached to the mounting bracket on the side of the house, and a heald placed at one end of the rope is wrapped around the human body, and the rope is braked by the speed governor to maintain a constant speed. There are machines that lower the human body while maintaining the same speed, and these types of speed governors are large and cannot be said to be portable. This has the disadvantage that the speed cannot be controlled to a speed other than the predetermined speed determined by the speed controller.

[Problem that the invention seeks to solve]

The present invention provides a small and portable slow descent machine equipped with a descending rope and a speed governor. Therefore, one end of the rope is fixed to a window frame or pillar of a house, and the other end is fixed to the ground. In a type of slow descent machine that can be lowered together with the main body of the slow descent machine by resting on the waist or holding the armpits on a belt fixed to the main body of the machine hanging nearby and engaged with the rope, the twisting of the rope It is characterized by the fact that it uses a gear mechanism to provide a braking effect, and the speed at which it descends can be freely controlled.

[Means for solving the problem] The slow descent machine of the present invention includes a strong rope having a twist, one end of which is fixed to a mounting member and the other end hanging near the ground, and the rope engages with the twist of the rope. A rope guide means consisting of a pulley with grooves formed on its circumferential surface and a plurality of guide rollers is provided, and a gear fixed to the shaft of the pulley is meshed with a gear of smaller diameter.
A speed regulating member is arranged on the shaft of a small diameter gear, and the cooking speed member is composed of a brake wheel, and a brake operation member having a curved part and a grip part that come into contact with and separate from the brake wheel, It is characterized by its small size and portability.

[For production]

The present invention fixes one end of the rope to a window frame, pillar, etc. of a building,
The other end hangs down close to the ground, and the machine descends while adjusting the descent speed while grasping the clamping part of the brake operation member provided on the main body of the slow descent machine. By forming grooves on the lead-in roller and the lead-out roller to fit the twist of the rope, the rope and pulley etc. are engaged, and together with the control of the speed regulating means, the speed during descent is controlled. It can be regulated reliably and freely. As a speed regulating means, the rotation of the pulley is increased and the speed of the increased brake wheel is freely controlled by automatic means or by a manual brake operating member, thereby making it possible to rotate the brake wheel one revolution.

〔Example〕

The present invention will be explained by examples.

FIG. 1 shows a portable evacuation machine main body 1 of the present invention, and a second
The figure shows the relationship between the rope 2 and the rope guiding means with the first board 7 removed.
It is made of a strong material with
The rope 2 is passed through the guide roller 6, and after passing through the guide roller 6, the rope 2 is wound onto a reel (not shown), and is suspended near the ground, serving to lower the gradual descent machine body 1 together with the human body. The rope 2 on the introduction roller 3 side is pulled out from the warming machine main body 1 by a length that can be attached to a window frame, pillar, etc. of a house.

The gradual descent machine main body 1 includes an introduction roller 3, a pulley 4, a lead-out roller 5, and a guide roller 6 arranged between a disk-shaped first substrate 7 and a disk-shaped second substrate 8. 4 is supported at one end by a bearing provided in a disk-shaped base Fj, 7;
It passes through the disk-shaped second substrate 8 and is fixed to a shaft 10 supported by a bearing of a cover frame 9, which will be described later.

The introduction roller 3 and the extraction roller 5 have a row 12 connected to the pulley 4.
They are arranged close to each other so as to be wound over almost the entire circumference, and are rotatably supported between the first substrate 7 and the second substrate 8.

A groove 4a shaped to engage with the twist 2a of the row 12 is formed on the circumferential surface of the pulley 4, so that the rope 2 and the pulley 4 are connected to each other.
This increases FJ friction due to contact with The peripheral surfaces of the introduction roller 3 and the extraction roller 5 are formed with 43a and 5a shaped to engage with the twist 2a of the rope 2, similarly to the pulley 4.

A guide plate 11 is provided on the outer periphery of the pulley 4 to help the row 12 come into contact with the pulley 4.
It is set at 8. It is also possible to arrange a plurality of guide rollers instead of the guide plate 11.

A guide roller 6 is arranged adjacent to the lead-out roller 5, and regulates the direction in which the row 12 is led out, and also controls the direction of the lead-out roller 5.
The range of contact between the rope 2 and the rope 2 is increased. It goes without saying that a guide roller can also be arranged on the introduction roller 3 side.

As can be understood from Figure 3, the same axis lo as pulley 4
A relatively large-diameter gear 12 is fixed above between the second substrate 8 and the cover frame 9, and the rotation of the pulley 4 is transmitted to the relatively large-diameter gear 12. This relatively large-diameter gear 12 meshes with a small-diameter gear 13, and the rotation of the pulley 4 is increased by the large-diameter gear 12 and the small-diameter gear 13. A brake wheel 14 is fixed to a shaft 18 to which a small-diameter gear 13 is attached, and both ends of the shaft 18 that fixes the small-diameter gear 13 and brake wheel 14 are provided on the second substrate 8 and the cover frame 9. It is supported by a bearing.

A brake operation member 15 is disposed around the brake wheel 14 and includes a curved portion 15a in contact with the outer circumferential surface of the brake wheel 14 and clamping portions 15b extending from the curved portion 15a. The member 15 has a mounting portion 15c provided outward from the center of the curved portion 15a attached to the second substrate 8 (16a).
, nuts 16b and 16c.

The brake wheel 14 has a large-diameter gear 12 and a small-diameter gear 13 that increase the rotation speed of the pulley 4 driven by the row 12.
By moving the curved portions 15a of 5 toward and away from each other, it is possible to change the braking effect, and in particular, by increasing the gripping force of the clamping portions 15b, 15b of the brake operating member 15, the descending speed can be slowed down. be able to.

The braking effect of the braking wheels 14 and the braking operation member 15 is as follows:
This is achieved by the frictional effect of the strand 2a and the groove 4a against the strand 23 on the contact surface between the row 12 and the pulley 4.

Instead of controlling the rotation of the brake wheel 14 provided on the shaft of the small diameter gear 13 to obtain a braking effect, it is also possible to provide the shaft of the small diameter gear 13 with an automatic speed governor such as a centrifugal governor.

Reference numeral 17 denotes a U-shaped belt attachment fitting provided between the first substrate 7 and the second substrate 8;
is a member for inserting and attaching a belt (not shown) on which the waist of a human body is placed or held at the side, and which connects ends 17a and 17b of the belt attachment fitting 17 to the first base plate 7 and the third base plate, respectively. It is rotatably attached to the second board 8.

20 is a bolt for attaching the belt attachment fitting 17 between the first substrate 7 and the second substrate 8, and the first substrate 7 and the second substrate 8 are spacers 21a.

Bolts 21b and 22b via 22a and 23a.

16a, and supported by nuts 21c, 22c, and 23c. 24, 25, and 26 respectively connect the large gear 12 to the shaft 1.
0, a screw to fix the small gear 13 to the shaft 18, and a screw to fix the brake wheel 14 to the shaft 18.

With the above configuration, when using the slow descent machine, one end of the row 12 is fixed to a mounting part such as a window frame or pillar of a house, and the belt attachment fitting 17 has an end portion of the belt that is hung around the waist. and drop the reel with the other end of the row 12 wound onto the ground.

After that, the brake operation member 1 extended from the main body of the gradual descent machine
5, and move the body supported by the belt from the building into the air. At this time, since the small diameter gear 13 is increasing the rotation speed of the pulley 4, the brake operation member 1
5 gives a braking effect to the braking wheel 14, and this braking effect is made more effective by the meshing of the twist 2a of the rope 2 with the grooves 4a, 3a, and 5a formed in the pulley 4, introduction roller 3, and lead-out roller 5. I consider it a thing. By changing the gripping force of the clamping portion 15b of the brake operation member 15, the contact friction between the rope 2 and the pulley 4, the introduction roller 3, and the lead-out roller 5, and the curved portion 15a of the brake operation member 15 and the brake wheel 14 can be adjusted. Due to contact friction, it is possible to descend at a predetermined speed.

In addition, in order to use the gradual descent machine body 1 of the present invention used for descent in its original state, the belt attachment fittings 17 placed on the lead-out roller side are separately placed on the lead-in roller side, thereby making it possible to The portable slow descent machine of the present invention can be used by removing the partially attached rope, turning the rope upside down, and performing the same operation as described above.

〔effect〕

In the present invention, grooves 4a that can fit with the twists 2a of the rope 2 are provided on the peripheral surfaces of the pulley 4, introduction roller 3, and lead-out roller 5 in the main body 1 of the gradual descent machine, so that the rope 2 and the pulley 4 can be connected to each other. This creates an interlock between them and eliminates slippage. Therefore, the shapes of the pulley 4, introduction roller 3, and lead-out roller 5 can be reduced in size, which has the advantage of being convenient to carry.

Moreover, the above-mentioned meshing engagement between the rope 2 and the pulley 4, together with the means for braking the brake wheel rotated by the accelerated configuration, has an effect suitable for changing the descending speed. This provides a configuration that brings about this.

As a related means, by adjusting the force applied to the grip part of the brake operation member with respect to the brake wheel being rotated at an increased speed, it has the effect of controlling the descending speed by a simple means,
Moreover, when descending, the grip of the brake operating member is not only useful for applying the brakes, but also for stabilizing the descending posture, and also for relieving anxiety in an emergency.
