[0005] It comprises: a variable ladder stored inside the main body (1) and configured to allow a fugitive to step downward and evacuate to the lower floor when the lower door (3) is opened; a door closing means (5) configured to directly close the upper door (2) to prevent the transfer and inflow of flames and toxic gases to the lower floor after the fugitive escapes; a door opening means (6) configured to open the lower door (3) so that the variable ladder stored inside the main body (1) can be unfolded to the lower floor; an emergency light (7) configured to be coupled to one side of the inner wall of the main body (1) and to brightly illuminate the surroundings for convenience of evacuation actions in the event of a power outage; and a lifting member (9) configured to be vertically movable between the main body (1) and the upper door (2), and configured such that when the main body (1) is embedded in a floor structure, the upper side of the main body (1) selectively protrudes from the upper surface of the building finishing material.

[0006] The main body (1) is intended to accommodate the door closing means (5) and the door opening means (6) in normal times, while also providing a passage for immediate evacuation from the floor below in the event of a disaster. It is composed of a main housing (11) that is installed downwardly spaced from the concrete slab(s) constituting each floor of the building and the floor surface of the slab(s) and is embedded up to a range close to the gypsum board (b) forming the ceiling of the floor below, and an extension housing (12) that can be installed in conjunction with the lower part of the main housing (11) and simultaneously extended freely to correspond to the gap between the slab(s) and the gypsum board (b).

[0007] To this end, one or more elongated holes (111) for adjusting the lifting range of the extension housing (12) are formed vertically through the lower side wall of the main housing (11), and a guide pin (121) capable of being inserted into the elongated hole (111) and moving up and down along the elongated hole (111) is formed protruding outwardly from the upper side wall of the extension housing (12).

[0008] It is preferable that the upper and lower doors (2, 3) be hinge-connected so as to open and close the uppermost part of the main housing (11) and the lowermost part of the extension housing (12) constituting the main body (1), respectively.

[0009] At this time, it is preferable that a moisture barrier (2a) is formed on the periphery of the upper door (2) to extend and surround the outer surface of the lifting member (9) when the upper part of the main body (1) is closed, thereby preventing water from penetrating into the interior of the main body (1).

[0010] More precisely, it wraps around the outer circumference of the contact portion (83) that is extended and bent from the bending rim portion (81) constituting the lifting member (9) described later.

[0011] Meanwhile, on the outer surface of the pivot side of the upper door (2), a gripping portion (21) is formed to facilitate opening the upper door (2) by grasping it with a person's hand.

[0012] A variable ladder is a means for evacuation movement from the floor where the disaster occurred to the floor below, and in this embodiment, a rope ladder is provided.

[0013] The above rope ladder (4) is composed of a plurality of ropes (41) extending from the main body to a position close to the floor surface of the lower floor, a plurality of stepping stones (42) connected at intervals suitable for a fugitive to step on in turn and descend to the lower floor between the ropes (41), and a fixing rod (43) connected to cross across one side of the exit of the main body so as to be able to tie the uppermost end of the rope.

[0014] Meanwhile, it is preferable to apply a fluorescent material to the outer surface of each of the stepping stones (42) so that the location of multiple stepping stones (42) can be identified through self-luminescence in a dark space, allowing the fugitive to step on them and go down to the lower floor.

[0015] The door closing means (5) is configured to manually close the upper door (2) directly for the purpose of preventing the fire from spreading to the lower floor after escape, and comprises a folding piece (51) which is connected so that the upper door (2) can be opened and closed by connecting each end of both sides to the bottom surface of one side of the upper door (2) and the inner wall surface of one side of the main housing (11); a wire (52) which pulls the folding piece (51) downward so that the upper door (2) can close the upper part of the main housing (11); a pull handle (53) which is connected to the bottom end of the wire (52) to facilitate pulling the folding piece (51); and a fixing clip (54) which pulls the upper door (2) while the wire (52) is in close contact with the side wall of the main housing (11).

[0016] The door opening means (6) is intended to close the lower part of the main body (1) with the lower door (3) to accommodate the rope ladder (4) and the door closing means (5) during normal times, while opening the lower door (3) so that the door closing means (5) and the door opening means (6) can be spread out to the lower floor during evacuation. As shown in FIGS. 5A and 5B, it comprises a lifting handle (61) that is exposed on one side of the interior of the main body (1) when the upper door (2) is opened, allowing an evacuee to grasp it with their hand and forcibly pull it up to release the closed state of the lower door (3); a cylinder (62) for raising the lifting handle (61) and subsequently restoring it to its original position; a first threaded bolt (63) formed to protrude downward integrally from the bottom of the cylinder (62); and a straight line formed on the lower side of the first threaded bolt (63). A second threaded bolt (64) having a ring-shaped hinge part (651) formed at the outermost end for hinge assembly with one side of the inner surface of the lower door (3) while being spaced apart, and a turnbuckle (65) which allows the mutually facing ends of the first and second threaded bolts (63) (64) to be connected through the upper and lower parts so that when rotating in forward and reverse directions, the distance between the mutually facing ends of the first and second threaded bolts (63) (64) can be adjusted to correspond to the gap difference between the main housing (11) and the extension housing (12) by adjusting the distance between them to be close or spaced apart, as the respective ends of the first and second threaded bolts (63) (64) are fastened through the upper and lower parts, and a fixing ring (66) which is attached to the inner surface of the lower door (3) with the hinge part (65-1) of the second threaded bolt (64) inserted, and a lifting handle (61) which can be fixed to the upper inner surface of one side of the main housing (11). It consists of an "L" shaped support ring (67).

[0017] Meanwhile, on the lifting handle (61), an L-shaped hook (61-1) is formed on one side so as to be hooked to the support hook (67), and at the bottom, a rod bar (612) having an expanded head that moves up and down within the cylinder (62) is integrally formed to extend downward.

[0018] Additionally, an elastic spring (621) is further provided inside the cylinder (62) to continuously pull down the extended head of the load bar (612) so that the hook (611) of the lifting handle (61) and the support hook (67) can be maintained in a securely locked state.

[0019] The emergency lighting (7) is intended to illuminate the surrounding objects so that it is easy to identify them when an escapee steps sequentially on the steps (42) of the rope ladder (4) and evacuates to the lower floor in a dark environment, such as during a power outage when the power supply is interrupted due to a fire. It is preferable that a light bulb (not shown) that automatically emits light when the upper door (2) is opened is built in, and this is made possible by a self-contained battery (not shown) that is additionally built in.

[0020] In addition, it is preferable to further include a buzzer (71) that emits an alarm sound to notify the surroundings of a fire (disaster) when the lower cover (3) is opened by operating the door opening means (6) for the purpose of escaping.

[0021] The lifting member (8) is configured to protrude while maintaining a horizontal position when the height is formed differently by the building finishing material (tile or cement) applied to the upper surface of the slab(s) when the main body (1) is embedded in the inter-floor structure, and comprises a bent rim portion (81) formed by bending in the outer direction and having an inner side corresponding to the outer circumference surface of the main body (1), and a contact portion (83) that is extended and bent inwardly to the bent rim portion (81) and has a receiving groove (82) of a predetermined depth so that the bent rim portion (81) can be fitted upwardly to the upper side of the main body (1).

[0022] At this time, it is preferable that the upper side of the main body (1) and the contact part (83), which are received in the receiving groove (82) of the contact part (83), are fixed through fastening means such as riveting or spot welding. Prior art literature

Specific details for implementing the invention

[0048] The present invention relates to an emergency escape elevator.

[0049] The motor (110) acts as a braking device by adjusting the speed within a certain range so that there is no significant difference in acceleration / deceleration due to weight.

[0050] By means of a high-efficiency motor (110), a reduction gear (120), and a spiral spring (400) The goal is to develop an emergency escape elevator that enables rapid and safe emergency escape.

[0051] Due to urbanization and the increase in high-rise buildings, there is a need for emergency escape elevators that can be used repeatedly without any power source in emergencies.

[0052] However, the underlying technology of the emergency escape system is expensive, and since the lifting device must necessarily be moved by a guide, there has been inconvenience caused by the necessary guide structures.

[0053] The present invention improves safety and user convenience by utilizing a miniaturized high-efficiency motor (110) and a reduction gear (120).

[0054] Conventional emergency escape elevators are high-cost, low-efficiency devices due to their large and complex designs, which result in high costs and render balconies and verandas unusable because of the escape device guide rails; furthermore, the complexity of the mechanism increases the likelihood of malfunctions.

[0055] The present invention requires the least amount of space, is low-cost, and has a simple configuration, thereby fundamentally eliminating the possibility of failure.

[0056] First, we will examine the main components used in the present invention and the configuration and effects according to those components.

[0057] The braking device for deceleration is configured as follows.

[0058] This is illustrated in FIGS. 3a to 3c.

[0059] A reduction gear (120) is utilized in a small motor (110) for a braking device for deceleration.

[0060] When a user boards the boarding unit (1300) using the reduction gear shaft (130), the reduction gear shaft (130) rotates, and current is generated in the motor (110) due to the rotating reduction gear shaft (130).

[0061] The generated current is removed through an appropriate power source or load.

[0062] The present invention was invented by applying and inventing the technology of a motor (110) that acts as a short brake.

[0063] The motor (110) is a 3v to 24v DC motor (110) commonly used in automatic devices, electronic products, toys, etc., and has the same structure, but the output is determined by the thickness of the coil, the number of turns, the capacity of the magnet, etc.

[0064] The greater the output, the greater the power consumed, and when the motor (110) is rotated by an external force, power is generated.

[0065] In other words, it converts kinetic energy into electrical energy.

[0066] The motor (110) can be a driving device and a generator.

[0067] The present invention converts kinetic energy into electricity through a motor (110), which is an electric motor, thereby generating electricity through kinetic energy, so that it functions as a brake device by means of kinetic energy of an appropriate force.

[0068] When the positive and negative poles of the DC motor (110) are connected to a load or power source and the motor (110) is rotated by an external force, a back electromotive force is generated. At this time, the generated current flows through a coil and is converted into heat by magnetic resistance, causing the kinetic energy to dissipate quickly or to stop as it is connected to a secondary battery to store energy.

[0069] The reduction gear (120) is widely used in mechanical devices mounted in front of the motor (110), and in the present invention, a planetary gear reduction gear is used as an example.

[0070] The structure of the planetary gear reducer is based on already invented technology, in which the gear rotation shaft is not fixed but mounted on a rotatable support.

[0071] This gear system rotates around its own axis, like a fixed-axis gear. The advantages of this planetary gear structure include being compact, lightweight, having a high reduction ratio, and high efficiency.

[0072] The reduction ratio of the reduction gear (120) is typically reduced in the form of 4:1 to 20:1.

[0073] When 20 rotations of the motor (110) correspond to 1 rotation of the reduction gear shaft, it is said to be a 20:1 reduction ratio.

[0074] The reason a reduction gear (120) must be attached to the emergency escape elevator (1000) is that a small motor (110) is installed to secure space, and when the motor (110) is driven with a high reduction ratio, it can be used as a short brake at a stable speed.

[0075] Electricity generated by driving the motor (110) by the force (weight of the occupant) flows through the coil, and kinetic energy is rapidly dissipated by magnetic resistance.

[0076] It regulates speed by smoothly distributing the weight of the passengers.

[0077] For the operating principle of the motor (110) reduction gear utilizing planetary gears, please refer to the following: https: / / youtube / knvrizfmq9U?si=AveKjBrNeorGCqyg

[0078] The short brake function is the motor (110) It is a braking system that reduces the possibility of failure through fast response and a simple structure utilizing the basic characteristics of.

[0079] When a heavy weight is placed on the boarding section (1300), the braking function becomes stronger, and when a light weight is placed on the boarding section (1300), the braking is applied weakly, so it is possible to escape safely at a constant speed.

[0080] That is, the motor (110) acts as a brake so that the user riding in the boarding section (1300) does not descend quickly due to the ratio of small weight to heavy weight, but rather the speed increases at a significantly small ratio relative to the weight.

[0081] The present invention utilizes the principle of regenerative braking of a motor (110).

[0082] It enables braking by converting the kinetic energy of the electric motor into electrical energy and returning it to the power source or load.

[0083] The one-way clutch (200) is as follows.

[0084] This is specifically illustrated in FIGS. 4a to 4c.

[0085] When the user is riding and moving downwards, the reduction gear shaft (130) of the motor (110) and the clutch outer sleeve (250) meet, and the brake is actuated so that the reduction gear shaft (130) and the clutch outer sleeve (250) rotate simultaneously, allowing the user to descend safely.

[0086] As illustrated in FIG. 4b, when the clutch outer sleeve (250) rotates counterclockwise, the bearing (210) pushes against the reduction gear shaft (130) in a locking direction, thereby locking it. As a result, the reduction gear shaft (130) and the clutch outer sleeve (250) rotate simultaneously in the same direction, generating a current in the motor (110) that converts kinetic energy into electrical energy, thereby operating the short brake by regenerative braking.

[0087] In addition, as shown in FIG. 4c, when the clutch outer sleeve (250) rotates clockwise, the bearing (210) pushes the spring (220) in the retainer direction and is pulled in, so that only the clutch outer sleeve (250) rotates without resistance and the reduction gear shaft (130) is not affected at all.

[0088] At this time, when the boarding part (1300) descends, the spiral spring (400) that was wound is released by elastic force, and the boarding part (1300) is returned to its original position.

[0089] The original position function is as follows.

[0090] This is illustrated in detail in Figs. 2a, 2b, 5a, and 5b.

[0091] When a user boards the boarding section (1300), the boarding section (1300) descends due to the weight of the person.

[0092] As the rotating part of the bobbin section (300) connected to the reduction gear shaft (130) rotates, the connecting line is unwound and the spiral spring (400) is wound.

[0093] At this time, the one-way clutch (200) operates to lower the speed by rotating the reduction gear shaft (130) to generate power and controlling the speed with an electric brake.

[0094] When a person gets off the boarding section (1300), the wound spiral spring (400) unwinds and the rotating section (310) rotates to rewind the connecting rope (320) back to its original position, preparing it for the next user to use.

[0095] FIG. 6a is a drawing showing a reduction gear attached motor (100) configured with a reduction gear shaft (130).

[0096] FIG. 6b is a diagram showing a reduction gear-attached motor (100) attached to a bracket part (500).

[0097] FIG. 6c is a diagram showing a one-way clutch (200) configured on a reduction gear shaft (130).

[0098] FIG. 6d is a diagram showing the state in which a bobbin portion (300) is configured on the clutch outer sleeve (250) of a one-way clutch (200).

[0099] FIGS. 7a and 7b are drawings showing a spiral spring (400) connected to a bobbin part (300) and a spiral spring fixing cover part (600) configured.

[0100] The following is an explanation focusing on the scope of the claims with reference to FIGS. 1a through 7b.

[0101] The frame part (1500) is configured.

[0102] A boarding section (1300) that moves around the frame section (1500) is configured.

[0103] The boarding section (1300) is configured so that the handle section (1400) is folded in a normal state and mounted on the same plane as the boarding section (1300).

[0104] The upper part is configured with a boarding cover (1200) which is a cover covering the boarding section (1300) to prevent the boarding section (1300) from descending unintentionally.

[0105] A rim cover portion (1100) is configured to cover the reduction gear-attached motor (100), one-way clutch (200), bobbin portion (300), and spiral spring (400) configured in the frame portion (1500).

[0106] The above-mentioned frame part (1500) is configured to have a braking function by configuring a motor (100) with a reduction gear attached thereto.

[0107] The detailed explanation is as previously stated.

[0108] A reduction gear shaft (130) is configured in the above reduction gear-attached motor (100).

[0109] A one-way clutch (200) is configured to surround the above reduction gear shaft (130).

[0110] The one-way clutch rotates simultaneously with the reduction gear shaft.

[0111] Due to rotation in opposite directions, they become independent of each other and do not influence one another.

[0112] The clutch outer sleeve of the above one-way clutch (200) and the bobbin portion (300) are connected, so that when the clutch outer sleeve rotates, the rotating shaft (315) configured in the bobbin portion rotates to unwind or wind the connecting rope (320).

[0113] The above bobbin part (300) is composed of a rotating part (310) and a connecting line (320).

[0114] The configuration is such that the boarding unit (1300) can ascend and descend as the connecting rope (320) unwinds and winds according to the rotation of the rotating part (310).

[0115] An emergency escape elevator has been invented that includes a configuration in which one end of the connecting rope (320) is attached to the boarding part (1300) and the other end of the connecting rope (320) is connected to the rotating part (310).

[0116] The above one-way clutch (200) is configured to rotate by engaging with the reduction gear shaft (130) when the boarding part (1300) moves downward, and when the boarding part (1300) moves to the frame part (1500), the one-way clutch (200) is configured to be free from the reduction gear shaft (130), so that when the spiral spring (400) exerts a force greater than the weight of the boarding part, the boarding part can be returned to its original position.

[0117] The inner end (410), which is one end of the spiral spring (400), is connected to the one-way clutch outer sleeve (250), and the outer end (420), which is the other end of the spiral spring (400), is mounted on the spiral spring fixing cover part (600) that surrounds the outside of the spiral spring.

[0118] A spiral spring (400) is further configured on one side of the bobbin section (300) and is configured to be linked with the rotation axis (315) of the rotation section (310). Therefore, when the boarding section (1300) moves downward, it rotates in the direction in which elastic force is applied to the spiral spring (400). When a user disembarks from the boarding section (1300), the boarding section (1300) is moved upward in the direction of the frame by the elastic force of the spiral spring (400), thereby rotating and reversing the rotation axis (315) to move the boarding section (1300) upward.

[0119] The above-mentioned boarding part (1300) has a handle part (1400) configured to allow the user riding to move safely downward.
