Description

Emergency escape elevator

[0001] The present invention relates to an inter-floor emergency escape elevator in a building. More specifically, it relates to an inter-floor emergency escape device that is installed by penetrating and embedding it into the inter-floor slab that partitions each floor of a building, and can be utilized as a means of evacuation for escaping to the floor below in the event of various disasters such as fire.

[0002] The technology forming the background of the invention is described as follows with reference to Drawing 8 of Korean Intellectual Property Office Patent Registration No. 10-1173585 (August 13, 2012).

[0003] The inter-floor emergency escape device (A) according to the background invention is a buried type that penetrates the inter-floor structure.

[0004] It is an installation structure. It comprises a main body (1) having a vertically open exit (1a) on the inside through which a person can enter and exit; and an upper door (2) and a lower door (3) provided at the upper and lower ends of the main body (1) to enable double opening and closing of the upper and lower parts of the exit (1a).

[0005] A variable ladder is configured such that, while stored inside the main body (1), when the lower door (3) is opened, the fugitive can step downward and evacuate to the lower floor.

[0006] A door closing means (5) is configured to directly close the upper door (2) for the purpose of preventing the transfer and inflow of flames and toxic gases to the lower floor after the escapee's escape.

[0007] A door opening means (6) is configured to open the lower door (3) so that the variable ladder housed inside the main body (1) can be extended to the lower floor.

[0008] An emergency light (7) is configured to illuminate the surroundings brightly for convenience of evacuation actions in the event of a power outage, while being coupled to one side of the inner wall of the main body (1).

[0009] And it is composed of a lifting member (9) that is interposed between the main body (1) and the upper door (2) so as to be vertically movable, and such that when the main body (1) is embedded in the interlayer structure, the upper side of the main body (1) is selectively protruded from the upper surface of the building finishing material.

[0010] The main body (1) is intended to accommodate the door closing means (5) and the door opening means (6) during normal times, while also providing a passage that allows immediate evacuation from the floor below in the event of a disaster.

[0011] A main housing (11) is constructed by configuring concrete slabs (s) that form each floor of a building and is installed downwardly spaced from the floor surface of the slabs (s) and embedded up to a range close to the gypsum board (b) that forms the ceiling of the floor below.

[0012] It is composed of an assembly structure of an extension housing (12) that can be installed in response to the gap between the slab(s) and the gypsum board (b) by connecting assembly to the lower part of the main housing (11) and simultaneously extending freely.

[0013] 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).

[0014] A guide pin (121) is formed protruding outwardly from the upper side wall of the above-mentioned elongated housing (12), which is inserted into the above-mentioned elongated hole (111) and simultaneously moves up and down along the elongated hole (111).

[0015] 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.

[0016] 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).

[0017] 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.

[0018] 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.

[0019] 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.

[0020] The above rope ladder (4) is provided with a plurality of ropes (41) extending from the main body to a position close to the floor surface of the lower floor, and is provided horizontally in succession between the ropes (41).

[0021] It consists of a plurality of stepping stones (42) each connected at intervals suitable for the fugitive to step forward and descend to the lower floor, and a fixing rod (43) connected to cross one side of the exit of the main body so as to be able to tie the uppermost end of the rope.

[0022] 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.

[0023] The door closing means (5) is intended to manually close the upper door (2) directly for the purpose of preventing the fire from spreading to the lower floor after escape.

[0024] The two sides are connected and assembled on one side bottom surface of the upper door (2) and one side inner wall surface of the main housing (11).

[0025] Accordingly, a folding piece (51) is configured to allow the upper door (2) to be opened and closed.

[0026] A wire (52) and a folding piece (51) are configured so that the folding piece (51) is pulled downward so that the upper door (2) can close the upper part of the main housing (11).

[0027] It consists of a pull handle (53) attached to the bottom end of the wire (52) to facilitate pulling the folding section, and a fixing clip (54) that allows the wire (52) to pull the upper door (2) while in close contact with the side wall of the main housing (11).

[0028] The door opening means (6) closes 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 operation.

[0029] On the other hand, the lower door (3) is opened so that the door closing means (5) and the door opening means (6) can be extended to the lower floor during evacuation.

[0030] When the upper door (2) is opened, one side of the interior of the main body (1) is exposed, so the fugitive grabs it with their hand and forcibly pulls it up to release the closed state of the lower door (3).

[0031] Meanwhile, on one side of the lifting handle (61), an L-shaped hook (61-1) is formed so as to be hooked to the support hook (67).

[0032] At the bottom, a rod bar (612) having an expanded head that moves up and down within the above cylinder (62) is integrally formed to extend downward.

[0033] 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.

[0034] The emergency lighting (7) is intended to illuminate the surrounding objects so that they can be easily identified 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.

[0035] 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 together.

[0036] In addition, it is preferable that a buzzer (71) is further built in which an alarm sound is emitted to notify the surroundings of the occurrence of a fire (disaster) when the lower cover (3) is opened by operating the door opening means (6) for the purpose of escaping.

[0037] The lifting member (8) is designed 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.

[0038] It is composed of a folded rim portion (81) formed by being folded outward 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 folded inwardly to the folded rim portion (81) and has a receiving groove (82) of a predetermined depth so that the folded rim portion (81) can be fitted upwardly and downwardly to the upper side of the main body (1).

[0039] 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.

[0040] The first problem that the invention aims to solve is the problem of space by minimizing the space occupied by the emergency escape device during normal times by not separately configuring components such as guide rails.

[0041] The second problem that the invention aims to solve is to prevent the possibility of failure of the emergency escape device in advance due to the simplification of parts.

[0042] The third problem that the invention aims to solve is that the cost burden of installing a separate emergency escape device is resolved because the components are simple and therefore very inexpensive.

[0043] The fourth problem that the invention aims to solve is to use an electric motor to rapidly store or release energy while converting kinetic energy into electrical energy.

[0044] By utilizing the motor as a braking function to prevent significant fluctuations in the descent speed based on the user's load, the braking function operates automatically even in a power-free state where no external power is supplied. This eliminates the need for a separate power source, thereby resolving the issue of power supply in emergencies.

[0045] The fifth problem that the invention aims to solve is to solve the difficult challenge of escaping for the disabled or patients by making it easy for those in critical condition to automatically escape downward without receiving power from an external source in an emergency.

[0046] To solve the above-mentioned problem, it has the following configuration.

[0047] Frame section;

[0048] A passenger unit that moves around the frame section;

[0049] A motor with a reduction gear configured in the above frame section;

[0050] A reduction gear shaft configured in the above reduction gear-equipped motor;

[0051] A one-way clutch configured to surround the above reduction gear shaft;

[0052] A bobbin portion connected to the clutch outer sleeve of the above-mentioned one-way clutch;

[0053] The above bobbin part is composed of a rotating part and a connecting line,

[0054] The above-mentioned rotating part is configured so that the above-mentioned connecting line unwinds and winds as it rotates, thereby allowing the boarding part to ascend and descend.

[0055] One end of the above connecting rope is attached to the boarding part, and the other end of the above connecting rope is connected to the rotating part, thereby constituting an emergency escape elevator.

[0056] Here, it is preferable that the one-way clutch be configured to rotate in engagement with the reduction gear shaft when the boarding part moves downward, and to be configured so that the one-way clutch is free from the reduction gear shaft when the boarding part moves to the frame part.

[0057] Here, it is preferable to configure a spiral spring on one side of the bobbin part (300) in conjunction with the rotation axis of the rotating part so that when the boarding part moves downward, it rotates in the direction in which elastic force is applied to the spiral spring, and when a user disembarks from the boarding part, the boarding part moves upward in the direction of the frame due to the elastic force of the spiral spring, thereby rotating and reversing the rotation axis to move the boarding part upward.

[0058] Here, it is desirable to configure the aforementioned boarding part with a handle so that the user can safely move downward.

[0059] The first effect of the invention is to maximize space utilization by not separately configuring components such as guide rails.

[0060] The second effect of the invention is to prevent the possibility of failure in advance due to the simplification of parts.

[0061] The third effect of the invention is that the parts are simple and the resulting cost is very low.

[0062] The fourth effect of the invention is to use an electric motor that converts kinetic energy into electrical energy and rapidly stores or releases energy, and to use the motor as a brake function so that the descent speed does not fluctuate significantly depending on the user's load.

[0063] The fifth effect of the invention is to enable severely disabled persons or patients to automatically escape downwards in an emergency without receiving power from an external source.

[0077] The present invention relates to an emergency escape elevator.

[0078] The motor (110) acts as a braking device by adjusting the speed within a certain range so that there is no significant difference in deceleration and acceleration due to weight.

[0079] The purpose is to develop an emergency escape lifting device that enables rapid and safe emergency escape through a high-efficiency motor (110), a reduction gear (120), and a spiral spring (400).

[0080] 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.

[0081] However, configuring the underlying emergency escape system is costly, and since the lifting device must necessarily move via guide rails, there has been inconvenience caused by the required guide structures.

[0082] The present invention improves safety and user convenience by utilizing a miniaturized high-efficiency motor (110) and a reduction gear (120).

[0083] Existing emergency escape elevators are large and complex in design, resulting in high costs and a significant amount of unusable space on balconies and verandas due to escape devices and guide rails.

[0084] Emergency escape elevators have been high-cost, low-efficiency devices, requiring a large amount of space and increasing the likelihood of malfunction due to their complex mechanisms.

[0085] The present invention not only requires the least amount of space but also fundamentally eliminates the possibility of failure due to its low cost and simple configuration.

[0086] First, we will examine the main components used in the present invention and the configuration and effects according to those components.

[0087] The braking device for deceleration is configured as follows.

[0088] This is illustrated in FIGS. 3a to 3c.

[0089] A reduction gear (120) is utilized in a small motor (110) for a braking device for deceleration.

[0090] 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).

[0091] The generated current is removed through an appropriate power source or load.

[0092] The present invention was invented by applying and inventing the technology of a motor (110) that acts as a short brake.

[0093] The motor (110) generally has the same structure as the 3v to 24v DC motors (110) commonly used in automatic devices, electronic products, toys, etc., but the output is determined by the thickness of the coil, the number of turns, and the capacity of the magnet.

[0094] The greater the output, the greater the power consumed, and power is generated when the motor (110) is rotated by an external force.

[0095] In other words, it converts kinetic energy into electrical energy.

[0096] The motor (110) can be a driving device and a generator.

[0097] The present invention converts kinetic energy into electricity through a motor (110), which is an electric motor, that is, generates electricity through kinetic energy, thereby enabling it to function as a brake device by means of kinetic energy of an appropriate force.

[0098] 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 electrical energy to be quickly dissipated or the motor to stop as the kinetic energy is dissipated by connecting it to a secondary battery to store energy.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] The reduction ratio of the reduction gear (120) is typically reduced in the form of 4:1 to 20:1.

[0103] It is said that when 20 rotations of the motor (110) correspond to 1 rotation of the reduction gear shaft, the reduction ratio is 20:1.

[0104] 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 brake at a stable speed.

[0105] 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.

[0106] It regulates speed by smoothly distributing the weight of the passengers.

[0107] FIG. 3c illustrates the configuration of a motor (110) reduction gear utilizing planetary gears.

[0108] The braking function is a braking system that reduces the possibility of failure through a simple structure and fast response using the basic characteristics of the motor (110).

[0109] 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.

[0110] 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 rate relative to the weight ratio.

[0111] The present invention utilizes the principle of regenerative braking of a motor (110).

[0112] It enables braking by converting the kinetic energy of the electric motor into electrical energy and returning it to the power source or load.

[0113] The one-way clutch (200) is as follows.

[0114] This is specifically illustrated in FIGS. 4a to 4c.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] The original position function is as follows.

[0120] This is illustrated in detail in Figs. 2a, 2b, 5a, and 5b.

[0121] When a user boards the boarding section (1300), the boarding section (1300) descends due to the weight of the person.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] FIG. 6a is a drawing showing a reduction gear attached motor (100) configured with a reduction gear shaft (130).

[0126] FIG. 6b is a diagram showing a reduction gear-attached motor (100) attached to a bracket part (500).

[0127] FIG. 6c is a diagram showing a one-way clutch (200) configured on a reduction gear shaft (130).

[0128] 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).

[0129] 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.

[0130] The following is an explanation focusing on the scope of the claims with reference to FIGS. 1a through 7b.

[0131] The frame part (1500) is configured.

[0132] A boarding section (1300) that moves around the frame section (1500) is configured.

[0133] 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).

[0134] 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.

[0135] 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).

[0136] The above-mentioned frame part (1500) is configured to have a braking function by configuring a motor (100) with a reduction gear attached thereto.

[0137] The detailed explanation is as previously stated.

[0138] A reduction gear shaft (130) is configured in the above reduction gear-attached motor (100).

[0139] A one-way clutch (200) is configured to surround the above reduction gear shaft (130).

[0140] The one-way clutch rotates simultaneously with the reduction gear shaft.

[0141] Due to rotation in opposite directions, they become independent of each other and do not influence one another.

[0142] The clutch outer sleeve (250) of the above one-way clutch (200) and the bobbin portion (300) are connected, so that when the clutch outer sleeve (250) rotates, the rotating shaft (315) configured in the bobbin portion (300) rotates to unwind or wind the connecting rope (320).

[0143] The above bobbin part (300) is composed of a rotating part (310) and a connecting line (320).

[0144] 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).

[0145] 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).

[0146] 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.

[0147] The inner end (410), which is one end of the spiral spring (400), is connected to the clutch outer sleeve (250) of the one-way clutch (200), 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.

[0148] 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.

[0149] The above-mentioned boarding part (1300) has a handle part (1400) configured to allow the user riding to move safely downward.

[0150] The configuration of the small-volume reduction gear attached motor (100), reduction gear shaft (130), one-way clutch (200), and bobbin part (300) can be sufficiently inserted into the rim cover part (1100) and thus occupies a very small volume spatially.

[0151] Terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings.

[0152] Based on the principle that an inventor can appropriately define the concept of a term to best describe their own invention, it must be interpreted in a meaning and concept consistent with the technical spirit of the present invention.

[0153] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0154] The present invention relates to an emergency escape elevator and is configured to allow safe evacuation to lower floors even when power is not supplied in the event of a fire in a high-rise building, and is industrially applicable.

[0155] It has industrial applicability as it has the effect of enabling severely disabled people or patients to automatically escape downwards in an emergency without receiving power from an external source.
