Description

Mechanical descending device for evacuation

The present invention relates to a mechanical personal automatic elevator, and more particularly, to a mechanical personal automatic elevator that enables multiple people to safely descend to the ground while maintaining a constant speed mechanically without using electricity in the event of a fire.

When a fire breaks out in a building, many people need to evacuate at the same time. Conventional fire escapes, which are evacuation devices installed in fire-fighting objects such as buildings, allow people to evacuate to the ground when the passageways within the building cannot be used in the event of a fire. However, it is difficult for multiple people to use them at the same time, and there is a risk of a falling accident if the user uses them in a hurry.

In addition, conventional mechanical fire extinguishers can be dangerous because the user must directly control the speed, and conventional electric fire extinguishers can be difficult to use in the event of a fire because they require electricity to drive the motor.

Patent Publication No. 10-2020-0090521 relates to a descender having an acceleration prevention function, which minimizes the heat generated between a deceleration unit and a rotating drum, thereby preventing an increase in acceleration during descent, thereby stabilizing the descent speed and preventing a fall accident of a victim in advance. However, there is a problem in that frictional heat due to slipping may be generated between the deceleration unit and the rotating drum, and since the frictional force must be adjusted to maintain a constant speed, it may be difficult to safely descend to the ground while maintaining a constant speed.

Patent Publication No. 10-1977952 relates to an emergency escape rope, and in order to improve safety by dispersing the force applied to the wire rope into the first take-up part and the second take-up part, the safety of the rope when used can be improved. The wire rope released from the first take-up part is wound around the take-up roller of the second take-up part, and as the take-up roller rotates, the first gear rotates, and the second gear rotates in engagement with it to generate braking force by the reduction device. The rotation speed of the brake pad wheel is reduced by the frictional force of the brake pad and the friction band, and the first gear is reduced by the second gear rotating together with the brake pad wheel, resulting in the take-up roller rotating slowly, so that the wire rope released through the second take-up part is slowly released, so that the rope does not fall freely when the rope is lowered, but rather descends slowly. However, frictional heat due to slippage is generated between the brake pad and the friction band. There is a problem that it may be difficult to safely descend to the ground while maintaining a constant speed, as friction must be controlled to maintain a constant speed.

Utility Model Publication No. 20-0476189 relates to an escape device for an evacuation apparatus, in which a plurality of brake pads are provided with cut grooves for heat dissipation, and first and second heat dissipation portions are provided on the reduction wheel and reduction wheel cover on which the brake pads are mounted, respectively, to release the high heat generated by the air cooling effect, thereby preventing the brake pads and reduction wheel cover, etc. from being damaged due to overheating, thereby enabling normal operation of the brake pads and maintaining a stable descent speed. However, there is still a problem in that frictional heat due to slipping may be generated between the brake pads and the reduction wheel, and since the frictional force must be controlled to maintain a constant speed, it may be difficult to safely descend to the ground while maintaining a constant speed.

Patent Publication No. 10-1311643 relates to a dual brake descender. In addition to the deceleration function using the centrifugal brake of a conventional descender, a separate brake system is added to further decelerate the device, so that the descender function can be safely operated even when the body weight of the evacuee is heavy. However, even in the separate brake system, the brake pads on the inside are in close contact with the drive gear drum of the drive gear part, causing frictional resistance to decelerate the rotation of the drive gear part. Therefore, there is still a problem in that frictional heat may be generated between the brake pads and the drive gear drum due to slipping, and since the frictional force must be adjusted to maintain a constant speed, it may be difficult to safely descend to the ground while maintaining a constant speed.

Hereinafter, the overall configuration and operation according to a preferred embodiment of the present invention will be described. These embodiments are exemplary and do not limit the configuration and operation of the present invention. Other configurations and operations that are not explicitly shown in the embodiments may be easily understood by a person having ordinary knowledge in the technical field to which the present invention belongs through the embodiments of the present invention below, and may be considered as technical ideas of the present invention.

Figure 1 schematically illustrates the interior and exterior of the mechanical personal automatic lifting machine of the present invention.

Referring to FIG. 1, the mechanical personal automatic evacuation device of the present invention is installed with a rope guide part (310, 320) inside a protective case (200) so that it can be safely lowered to the ground while maintaining a constant speed mechanically without using electricity in the event of a fire, and the rope penetrating the inside of the protective case (200) is moved while maintaining a constant speed.

When a fire breaks out in a building, the user simply attaches the protective case (200) to a part of his or her body and hangs, allowing the user to safely descend to the ground while automatically maintaining a constant speed.

In Fig. 1, the inside of the protective case (200) is shown as being visible from the outside for explanation purposes, but the inside of the protective case (200) can be sealed on all sides except for the opening through which the rope passes.

When a fire breaks out in a building, many people need to evacuate at the same time. Conventional escape devices are not only not easily usable by users, but also make it impossible for multiple people to hang from a single rope and use them simultaneously. However, the mechanical personal automatic escape device of the present invention is easily usable by users, and allows multiple people to hang from a single rope and use them one after another simultaneously.

FIG. 2 is a perspective view of one internal side of the mechanical personal automatic lifting machine of the present invention.

Referring to FIG. 2, the mechanical personal automatic lifting machine of the present invention includes a first driving drum part (410), a second driving drum part (420), and a third driving drum part (430) that are installed inside a protective case (200) and rotate in close contact with both sides of the rope between the rope guide parts (310, 320) so that the rope passing through the inside of the protective case (200) moves while maintaining a constant speed.

Although not shown in FIG. 2, in order to ensure that the first driving drum unit (410), the second driving drum unit (420), and the third driving drum unit (430) are elastically and closely attached to both sides of the rope, the rotation axis of at least one of the first driving drum unit (410), the second driving drum unit (420), and the third driving drum unit (430) may be formed to have elasticity with respect to the rope.

In Fig. 2, the rope is not depicted and is omitted, but the rope is arranged along a rope guide section (310, 320), and a first driving drum section that rotates in close contact with one side of the rope, that is, the left side of the rope in Fig. 2, is arranged, and a second driving drum section and a third driving drum section that rotate in close contact with the other side of the rope, that is, the right side of the rope in Fig. 2, are arranged.

The arrangement of the first driving drum unit (410), the second driving drum unit (420), and the third driving drum unit (430) is only one embodiment, and either the second driving drum unit (420) or the third driving drum unit (430) may be omitted or other driving drum units may be additionally arranged.

FIG. 3 is a perspective view of another internal aspect of the mechanical personal automatic lifting machine of the present invention.

Referring to FIG. 3, the mechanical personal automatic climbing machine of the present invention has a rope guide section (310, 320) installed inside a protective case (200), and includes a first driving drum section (410), a second driving drum section (420), and a third driving drum section (430) that are in close contact with and rotate on both sides of the rope between the rope guide sections (310, 320) so that the rope penetrating the inside of the protective case (200) moves while maintaining a constant speed, and a first driven gear (510) that is coaxially fixed to the second driving drum section (420) is arranged at the lower portion of the second driving drum section (420), and a second driven gear (520) that is coaxially fixed to the third driving drum section (430) is arranged at the lower portion of the third driving drum section (430).

In order to transmit rotational power to the first driven gear (510) and the second driven gear (520), a driving gear (600) is arranged between them, and an escapement wheel (700) is arranged coaxially and closely fixed to the lower portion of the driving gear (600).

Escapement wheel teeth (710) are formed on the outer surface of the escapement wheel (700), and when force is applied to the rope (10) by the user, it rotates while maintaining a constant speed.

In order to allow the escapement wheel (700) to rotate at a constant speed, a balance wheel (800) that generates rotational vibration around a rotational axis is arranged, and a pallet fork (900) that transmits the rotational vibration of the balance wheel (800) to the escapement wheel (700) is arranged.

A balance spring (810) is connected to the rotation axis of the balance wheel (800), and as the contraction and expansion of the balance spring (810) are repeated, rotational vibration of the balance wheel (800) is generated.

The rotational vibration of the balance wheel (800) is transmitted to the pallet fork (900), and the escapement wheel (700) is rotated at a constant speed through the pallet fork (900). The escapement wheel (700) is rotated at a constant speed as the escapement wheel teeth (710) turn one by one during a half cycle of the rotational vibration of the balance wheel (800).

The configuration that rotates while maintaining a constant speed by the escapement wheel (700), the balance wheel (800), and the pallet fork (900) is generally used as an internal component of a watch using a mechanical movement, but the present invention transmits the constant speed of the escapement wheel (700) to the driving drum part through a gear structure or the like in order to apply the configuration that rotates while maintaining a constant speed by the escapement wheel (700), the balance wheel (800), and the pallet fork (900) to a watch.

Figure 4 illustrates a rope penetrating the interior of a mechanical personal automatic lifting machine according to the present invention.

Referring to FIG. 4, the mechanical personal automatic lifting machine of the present invention installs a rope guide part (310, 320) inside a protective case (200) and arranges a first driving drum part (410), a second driving drum part (420), and a third driving drum part (430) between the rope guide parts (310, 320) so that a rope (10) penetrating the inside of the protective case (200) moves while maintaining a constant speed, thereby rotating while being in close contact with both sides of the rope (10).

A first driven gear (510) is arranged at the lower portion of the second driving drum unit (420) and is coaxially fixed to the second driving drum unit (420). A second driven gear (520) is arranged at the lower portion of the third driving drum unit (430) and is coaxially fixed to the third driving drum unit (430). A driving gear (600) is arranged between the first driven gear (510) and the second driven gear (520). An escapement wheel (700) is arranged at the lower portion of the driving gear (600) and is coaxially fixed to the lower portion of the driving gear (600).

The escapement wheel (700) rotates at a constant speed by the rotational vibration of the balance wheel (800), and the drive gear (600) rotates together with the escapement wheel (700) to cause the first driven gear (510) and the second driven gear (520) to rotate at a constant speed.

The second driving drum unit (420) and the third driving drum unit (430), which are coaxially and closely fixed to the first driven gear (510) and the second driven gear (520), respectively, allow the rope (10) to move while maintaining a constant speed, and together with the first driving drum unit (410), hold the rope (10) from both sides.

Ultimately, the present invention does not generate frictional heat due to slipping and does not require the control of frictional force to maintain a constant speed, and allows the user to safely descend to the ground while maintaining a constant speed without the need to control frictional force according to the user's body weight.

FIG. 5 illustrates another embodiment of the mechanical personal automatic lifting machine of the present invention.

Referring to FIG. 5, the present invention has an escapement wheel (700) coaxially fixed to the lower part of the first driving drum part (410) of the mechanical personal automatic lifting device of the present invention, and when the user's body weight is transmitted to the first driving drum part (410) through a rope (10), the first driving drum part (410) rotates while maintaining a constant speed.

In addition, by adjusting the radius of the escapement wheel (700) considering the user's weight, it is possible to safely descend to the ground while maintaining a more constant speed.

The position and radius of the above escapement wheel (700) can be changed to generate constant rotation of the first driving drum unit (410), the second driving drum unit (420), and the third driving drum unit (430), and a plurality of escapement wheels (700) can be installed.

Of course, the balance wheel (800) and the pallet fork (900) are also connected together for constant rotation of the escapement wheel (700).
