Description

Technology Field

[0001] The present invention relates to a sealing member mounted on an opening and closing door of a storage space to seal a gap between the door and a container frame or between adjacent doors when the door is closed, and a storage space including the same. Background Technology

[0003] Generally, a sealing member (4) is installed along the edge of the door (2) of the container (1) to block the entry of moisture, air, dust, etc. from the outside. For example, as shown in FIG. 1, the sealing member (4) is attached along the upper, side, and lower edges of the door (2) of the container (1) and performs a sealing function by coming into contact with the frame (3) when the door (2) is closed.

[0004] Conventional sealing (4) members, as shown in FIG. 2(A), often have a sealing (4) contact portion formed in a flat shape that contacts the frame (3) or the adjacent door (2). However, in this structure, a gap may occur between the door (2) and the frame (3) due to manufacturing errors, installation errors, or deformation during use of the door (2) and the frame (3), and this causes a problem in that the sealing (4) performance is degraded.

[0005] To improve these problems, a structure was proposed to increase contact pressure by tilting the sealing (4) contact portion outward or inward or forming it in a curved shape, as shown in FIG. 2(B). However, as shown in FIG. 2(C), such a structure may cause the sealing (4) member to be folded and rolled inward by the door (2) or frame (3) during the opening and closing process of the door (2), and there was a problem of causing deformation or damage to the sealing (4) member due to repeated opening and closing.

[0006] Furthermore, in the case of a structure in which multiple doors (2) are arranged adjacently and opened and closed in a folding manner, there was a problem in that the sealing members (4) attached to each door (2) interfered with each other, resulting in a failure to achieve normal sealing, or a gap between the doors (2) due to the interference. Along with this, there was also a problem in that the door (2) did not close completely due to excessive elasticity or reaction force of the sealing members (4), or an unnecessary increase in weight when opening and closing the door (2). Prior art literature

[0008] Korean Utility Model Publication No. 20-1999-0000394 The problem to be solved

[0009] The present invention is made to solve the problems of the prior art as described above, and its main purpose is to provide a sealing member that ensures stable sealing without gaps between a door and a frame or between adjacent doors, while preventing the sealing member from being folded or rolled in or abnormally deformed during the opening and closing process of the door.

[0010] In addition, another objective is to provide a sealing member that minimizes interference between sealing members attached to each door in a structure where multiple doors are opened and closed in adjacent positions, thereby suppressing the occurrence of gaps between doors and maintaining a stable sealing state.

[0011] In addition, the purpose is to provide a sealing member that can improve the problem of door closing being hindered by the sealing member or the heavy operating sensation during door opening and closing due to excessive reaction force while ensuring sealing performance.

[0012] Other objects and advantages of the present invention may be understood from the following description and will become more clearly apparent from the embodiments of the present invention. Furthermore, it will be readily apparent that the objects and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims. means of solving the problem

[0014] According to the present invention, a sealing member is provided that is mounted on the edge of a door provided in a storage space and seals a gap formed between the door and an opposing member positioned opposite thereto when the door is closed.

[0015] The sealing member is formed to extend along the upper, side, and lower portions of the door and includes a first portion, a second portion, and a third portion that are continuous with one another, and has a cross-sectional shape orthogonal to the extension direction that is commonly applied to at least a portion of the first to third portions, and is fixed to the door; an insertion sealing portion formed on one side of the base portion and inserted into the gap between the door and the opposing member during the process of closing the door to seal the interior of the gap; and a cover portion formed on the other side of the base portion and arranged to cover the outside of the gap.

[0016] The above cover portion may include: a cover sealing portion that seals the gap by pressing the outer side of the opposing member when the door is closed; and a cover fixing portion that extends to the base of the cover sealing portion and supports the cover sealing portion by contacting the outer side of the door.

[0017] The above cover sealing portion includes an end formed by bending, and can seal the gap by pressing the opposing member with the bent end.

[0018] The above cover sealing portion may be positioned so that the entire portion faces the opposing member when the door is closed, at an angle in a predetermined direction.

[0019] The cover sealing portion comprises: a second sealing portion bent to perform sealing by directly contacting the opposing member as the bent end; and a first sealing portion that supports the second sealing portion while being spaced apart from the opposing member; wherein the first sealing portion may be configured to transmit a reaction force transmitted through the cover fixing portion to the second sealing portion while not being in direct contact with the opposing member.

[0020] The above cover fixing part may include a first fixing part directly coupled to the base part and the cover sealing part, and a second fixing part extending from the first fixing part and contacting the outer side of the door.

[0021] The second fixing part is formed such that its cross-sectional thickness is reduced compared to the first fixing part, thereby reducing the transmission of the reaction force generated by contact with the outside of the door to the cover sealing part.

[0022] The above cover fixing part may be configured to include a shape that is inwardly recessed in at least a portion of the section extending from the first fixing part to the second fixing part, so as to reduce the reaction force of the cover fixing part.

[0023] The above cover fixing part may have a recess formed between the first fixing part and the second fixing part to relieve reaction force.

[0024] The sealing member further includes an L-shaped connecting portion that connects sections extending in different directions among the sections, the cross-sectional shape is applied to the connecting portion, and the cover sealing portion of the connecting portion may further include an auxiliary sealing portion.

[0025] The above auxiliary sealing part may be formed to protrude from the top of the cover sealing part.

[0026] The sealing member further includes an end finishing portion at least at one end, and the end finishing portion is formed such that the end of the insertion sealing portion and the cover sealing portion protrudes in the lateral direction of the door, and may be formed in a shape such that the protrusion length in the lateral direction of the door increases as it moves away from the base portion.

[0027] The cover sealing portion of the above end finishing portion can be formed so that the cross-sectional thickness gradually decreases as it approaches the end.

[0028] According to the present invention, a sealed door is provided comprising: a door that can be opened and closed; and a sealing member disposed along the upper surface, one side surface, and the lower surface of the door, wherein the insertion sealing portion and the cover sealing portion are formed to extend in the same direction relative to the base portion, the door is coupled to one side of the base portion where the insertion sealing portion and the cover sealing portion are not formed, and the cover fixing portion is located adjacent to the front surface of the door.

[0029] According to the present invention, in a storage space in which an internal space is formed by a frame,

[0030] A storage space is provided that includes a sealed door that is openable and closable to an opposing member. Effects of the invention

[0032] According to the sealing member of the present invention, when the door is closed, the sealing member is stably attached to the frame or an adjacent door, thereby ensuring excellent sealing performance without gaps between the door and the frame or between the doors.

[0033] In addition, due to the shape and arrangement of the sealing member, the phenomenon of the sealing part folding inward or abnormally deforming during the door opening and closing process is suppressed, so the sealing performance can be stably maintained even with repeated opening and closing.

[0034] In particular, even in a structure where multiple doors are opened and closed in adjacent positions, interference between sealing members attached to each door is minimized, thereby suppressing the occurrence of gaps between doors and ensuring a normal closed state of the doors.

[0035] Furthermore, the generation of unnecessary reaction force due to the sealing member is reduced, preventing excessive weight during door opening and closing; consequently, this provides the effect of improving user convenience and enhancing the durability of the door and the sealing member.

[0048] The present invention relates to a sealing member (1000) mounted on an opening / closing door (2100) of a storage space (3000) to seal a gap between the door (2100) and a frame (3100) or between adjacent doors (2100) when the door (2100) is closed, and a storage space (3000) including the same.

[0049] The storage space (3000) to which the sealing member (1000) according to the present invention is applied is not particularly limited as long as it is a structure that needs to seal the internal space from the external environment, and may include, for example, a logistics container, a housing of an Energy Storage System (ESS), an industrial cabinet, an electrical equipment housing, a chamber of a refrigeration / freezing facility, etc.

[0050] The sealing member (1000) of the present invention may be formed from a polymer material having elasticity and resilience so as to maintain stable sealing performance even under repeated opening and closing and compressive deformation of the door (2100). For example, the sealing member (1000) may be formed from a material including at least one of EPDM, silicone resin, fluoropolymer, thermoplastic elastomer (TPE), vulcanized thermoplastic elastomer (TPV), chloroprene rubber (CR), and nitrile rubber (NBR), but is not limited thereto.

[0052] FIGS. 3 to 17 relate to a sealing member (1000), a sealed door (2000), and a storage space (3000) of the present invention.

[0053] Hereinafter, specific embodiments of the sealing member (1000) of the present invention, the sealed door (2100) including the same, and the storage space (3000) will be described in detail with reference to the attached drawings. For reference, the directions of front, back, up, down, left, and right used to specify relative positions in the following description are intended to aid in understanding the invention, and unless otherwise specifically defined, the directions shown in the drawings are used as the reference.

[0056] FIG. 3 is a perspective view of a sealing member (1000) according to an embodiment of the present invention, FIG. 4 is a front view of the sealing member (1000) shown in FIG. 3, FIG. 5 is a front view of a sealed door (2000) in which a door (2100) and a sealing member (1000) are combined, FIG. 6 is a cross-sectional view of the sealing member (1000) shown in FIG. 4 cut by each part, FIG. 7 is a drawing for explaining the angle range between the first sealing part (221) and the second sealing part (222), and FIG. 8 is a schematic drawing showing the state in which the sealing member (1000) seals the gap between the door (2100) and the opposing member (Om).

[0058] Referring to FIGS. 3 to 6, a sealing member (1000) according to one embodiment of the present invention is mounted on the edge of an opening / closing door (2100) of a storage space (3000) and configured to seal a gap formed between the door (2100) and an opposing member (Om) positioned opposite thereto when the door (2100) is closed.

[0059] In the present invention, "opposing member (Om)" refers to a member that is positioned adjacently to face a sealing member (1000) mounted on the door (2100) when the door (2100) is closed, and performs a sealing action between the sealing member (1000) and the door.

[0060] The above-mentioned opposing member (Om) may be a frame (3100) constituting a storage space (3000) in which the door (2100) is installed, and in the case where a plurality of doors (2100) are arranged adjacently, it may be another door (2100) adjacent to the door (2100).

[0062] The sealing member (1000) is formed to extend along the upper, side, and lower portions of the door (2100) and includes a first portion (100a), a second portion (100b), and a third portion (100c) that are continuous with one another.

[0063] The sealing member (1000) is formed in a 'C' or 'inverted C' shape so as to extend along the upper surface, one side surface, and lower surface of the door (2100), and includes a first part (100a), a second part (100b) connected to one end of the first part (100a), and a third part (100c) connected to one end of the second part (100b).

[0064] The sealing member (1000) is formed in a '□' shape so as to extend along the upper surface, both sides and the lower surface of the door (2100), and includes a first portion (100a), a pair of second portions (100b) each connected to both sides of the first portion (100a), and a third portion (100c) to which the ends of each second portion (100b) are connected to both sides.

[0066] A cross-sectional shape that is commonly applied to at least a portion of the first part (100a) to the third part (100c) is formed, and the cross-sectional shape includes a base part (100), an insertion sealing part (300), and a cover part (200) as shown in FIG. 5.

[0068] Referring to FIG. 5, the sealing member (1000) of the present invention comprises, in a cross section perpendicular to the extension direction, a base portion (100) attached to the door (2100), an insertion sealing portion (300) extending from the base portion (100) and sealing the space between it and the opposing member (Om), and a cover portion (200) formed on the upper side of the base portion (100) and in contact with the opposing member (Om).

[0070] The base portion (100) is a part for the sealing member (1000) to be fixed to the edge of the door (2100), and is fixed to the edge of the door (2100) by fitting into a mounting groove formed in the door (2100) or by a connecting member such as a bolt that is combined with a separate horseshoe and passes through the horseshoe and the base portion (100) to be screw-coupled to the door (2100).

[0072] The above-mentioned insert sealing portion (300) is formed by extending downward from the base portion (100) and is inserted into the gap between the door (2100) and the opposing member (Om) when the door (2100) is closed to perform a sealing function.

[0073] The insert sealing portion (300) may be formed with a shorter length than the cover portion (200) and is positioned at an angle, curving toward the base portion (100).

[0074] The above-mentioned insert sealing part (300) is formed of an elastic material and configured to provide a sealing force by elastically deforming when pressed by an opposing member (Om).

[0075] In particular, the insert sealing portion (300) is formed in a curved or hook shape in cross-section to prevent detachment when pressure is applied and to maintain a stable sealing state.

[0077] The above cover portion (200) is formed on the upper side of the base portion (100) and performs a secondary sealing action by directly contacting the opposing member (Om) when the door (2100) is closed.

[0078] The above cover portion (200) includes a cover sealing portion (220) and a cover fixing portion (210).

[0080] The cover sealing portion (220) is formed to extend in the same direction as the direction in which the insertion sealing portion (300) extends from one side of the base portion (100), but is positioned at an angle opposite to the angled direction of the insertion sealing portion (300).

[0081] The above cover sealing part (220) is configured to seal the gap by pressing the outer side of the opposing member (Om) when the door (2100) is closed.

[0082] The above cover sealing portion (220) includes an end formed by bending, and sealing is performed by pressing the opposing member (Om) with the bent end. That is, the end of the cover sealing portion (220) is formed in a bent shape that is oriented toward the base portion (100) in a direction different from the extension direction.

[0083] The above cover sealing portion (220) is positioned so that its entire surface is inclined toward the opposing member (Om) when the door (2100) is closed, and is configured to make surface contact or line contact when in contact with the opposing member (Om).

[0085] The cover fixing part (210) is formed to extend in a direction opposite to the direction in which the cover sealing part (220) extends from one side of the base part (100), and is positioned at an angle in the same direction as the angled direction of the cover sealing part (220).

[0086] The above cover fixing part (210) serves to fix the above cover sealing part (220) to the door (2100) and, at the same time, maintain the reaction force of the above cover sealing part (220) by supporting the load generated in the above cover sealing part (220) when the door (2100) is closed.

[0087] The cover fixing part (210) includes a first fixing part (211) that is directly coupled to the base part (100) and the cover sealing part (220), and a second fixing part (212) that extends from the first fixing part (211) and contacts the outside of the door (2100).

[0088] The second fixing part (212) may be formed such that its cross-sectional thickness is reduced compared to the first fixing part (211), and accordingly, the reaction force acting on the cover fixing part (210) due to contact with the outside of the door (2100) may be suppressed from being directly transmitted to the cover sealing part (220).

[0089] The second fixed part (212) includes a depression (210a) formed by a reduction in cross-sectional thickness at the boundary with the first fixed part (211).

[0090] The above-mentioned recess (210a) is formed by being indented inwardly from the inner surface of the second fixed part (212), and functions as an area where deformation is concentrated when the second fixed part (212) is pressed by an external force.

[0091] Accordingly, when the cover fixing part (210) receives a pressing force relative to the base part (100), the second fixing part (212), which has a relatively thin cross-sectional thickness, is deformed preferentially, and the reaction force acting on the entire cover fixing part (210) is mitigated by the shape change of the recessed part (210a).

[0092] That is, among the reaction forces acting on the cover fixing part (210), the excessive reaction force caused by contact with the outside of the door (2100) is preferentially absorbed and mitigated by the deformation of the recessed part (210a).

[0093] The reaction force after being relieved by the above-mentioned depression (210a) is transmitted to the second sealing part (222) via the first sealing part (221) to provide the pressure necessary for sealing maintenance.

[0094] Meanwhile, if a structure that performs a cushioning function such as the second fixing part (212) is not provided, the reaction force acting on the cover fixing part (210) may not be sufficiently relieved and may be directly transmitted to the end of the cover sealing part (220).

[0095] In this case, the end of the cover sealing part (220) acts in a direction that pushes the opposing member (Om) excessively, so that the closing resistance increases during the process of closing the door (2100), or a problem may occur where a relatively large force is required to close the door (2100).

[0097] FIG. 6 is a schematic diagram showing a portion of a 'C'-shaped sealing member (1000) that is continuously connected to the upper surface (2100c), side surface (2100b), and lower surface of a door (2100). The base portion (100) included in the first portion (100a) of the sealing member (1000) is connected to the upper surface (2100c) of the door (2100) such that the cover portion (200) faces the front of the door (2100), and the insert sealing portion (300) is positioned on the upper surface (2100c) of the door (2100) and is positioned so as to face upward.

[0098] The base portion (100) included in the second portion (100b) of the sealing member (1000) is positioned so that the cover portion (200) faces the front of the door (2100) and is coupled to one side (2100b) of the door (2100), and the insert sealing portion (300) is positioned on one side (2100b) of the door (2100) and is positioned upright so as to face the side of the door (2100).

[0099] The base portion (100), cover portion (200), and insertion sealing portion (300) included in the third portion (100c) of the sealing member (1000) are arranged symmetrically with respect to the base portion (100), cover portion (200), and insertion sealing portion (300) of the first portion (100a).

[0101] Referring to FIGS. 5 and 7, the cover sealing portion (220) includes a first sealing portion (221) that is directly coupled to the base portion (100) and extends in one direction, and a second sealing portion (222) that extends from the first sealing portion (221) and is formed to be inclined toward the base portion (100), and which secondarily seals the gap by pressing the outer side of the opposing member (Om) when the door (2100) is completely closed.

[0102] The second sealing part (222) is a bent end of the cover sealing part (220) and performs sealing by directly contacting the opposing member (Om), and the first sealing part (221) is positioned at a distance from the opposing member (Om) while supporting the second sealing part (222).

[0103] Referring to FIG. 7, the first sealing portion (221) is formed at an angle (a1) of approximately 90° or more with respect to the extension line of the inner surface of the base portion (100) (reference line indicated by a dotted line in the drawing).

[0104] At this time, the inclined angle (a1) of the first sealing part (221) is intended to prevent the end of the cover sealing part (220) from being rolled in between the door (2100) and the opposing member (Om) during the process of closing the door (2100), and is set to a range that does not deviate significantly from 90°, and preferably can be formed to be about 100° or less.

[0105] Meanwhile, the second sealing portion (222) is bent and extended from the first sealing portion (221), and is formed to form an acute angle with respect to the extension direction of the first sealing portion (221).

[0106] More specifically, the second sealing part (222) may be formed at an angle of approximately 20° to 60° relative to the extension direction of the first sealing part (221), thereby mitigating interference during the opening and closing process of the door (2100) and maintaining a stable sealing contact state.

[0108] FIGS. 9 and 10 are conceptual drawings showing the direction of force transmission acting on the sealing member (1000) during the process of closing the door (2100).

[0109] Specifically, FIG. 9 is a drawing showing the direction of the force acting on the sealing member (1000) of the first part (100a) or the second part (100b) when the door (2100) is closed, and FIG. 10 is a drawing showing the direction of the force acting on the sealing member (1000) of the second part (100b) when the door (2100) is closed.

[0110] In the process of the door (2100) moving toward the opposing member (Om) and closing, the second sealing part (222) included in the cover sealing part (220) is pressed by the opposing member (Om), and accordingly, a compressive force is applied to the second sealing part (222) from the opposing member (Om).

[0111] The compressive force acting on the second sealing part (222) is transmitted along the interior of the sealing member (1000) and transmitted to the first sealing part (221). At this time, the base part (100) fixed to the door (2100) acts as a structurally fixed point, and the first sealing part (221) behaves similarly to a lever with respect to the base part (100).

[0112] The force transmitted to the first sealing part (221) is transmitted to the cover fixing part (210), and accordingly, the cover fixing part (210) has a tendency to deform in a direction toward the door (2100).

[0113] In this process, the second fixing part (212), including the recess (210a) formed in the cover fixing part (210), is elastically deformed by the pressure, and the deformation of the second fixing part (212) is within the range allowed by the elastic limit of the material or the structural shape.

[0114] When the second fixing part (212) is supported by the door (2100) and reaches a state where further deformation is restricted, a reaction force from the door (2100) acts on the cover fixing part (210), and the reaction force is transmitted in the direction of the cover sealing part (220).

[0115] Accordingly, the reaction force is transmitted to the second sealing part (222) via the first sealing part (221), and the second sealing part (222) is pressed again toward the opposing member (Om) and comes into close contact with the opposing member (Om).

[0116] As a result, the second sealing part (222) maintains a state of continuously pressing the opposing member (Om), and a stable sealing state is formed between the door (2100) and the opposing member (Om).

[0117] The sealing member (1000) of the present invention has a structure in which the first sealing part (221) does not come into contact with the opposing member (Om), so it is not deformed by external force and can focus on acting as a transmitter to transmit the force generated in the second sealing part (222) to the cover fixing part (210). In addition, conversely, the sealing force can be increased by transmitting the reaction force of the cover fixing part (210) to the second sealing part (222).

[0118] Accordingly, through the first sealing part (221) which does not come into direct contact with the opposing member (Om), a force transmission path is clearly formed within the sealing member (1000), thereby effectively redistributing the load generated during the closing process of the door (2100) to the cover fixing part (210) and the cover sealing part (220). As a result, the sealing performance is stably maintained, and structural reliability is improved even with repeated opening and closing.

[0120] FIG. 11 is a drawing showing the configuration of a connecting part (100d) and an end finishing part (100e) included in a sealing member (1000), FIG. 12 is a perspective view showing the connecting part (100d), FIG. 13 is a front view and a cross-sectional view of the connecting part (100d) shown in FIG. 12, FIG. 14 is a perspective view of the end finishing part (100e), FIG. 15 is a front view and a cross-sectional view of the end finishing part (100e) shown in FIG. 14, and FIG. 16 is a drawing showing the state in which the connecting part (100d) and the end finishing part (100e) overlap in a sealed door (2000) arranged side by side.

[0122] The sealing member (1000) of the present invention may further include an L-shaped connecting part (100d) that connects sections extending in different directions among the sections.

[0123] Referring to FIGS. 11 and 12, the connecting portion (100d) is formed to connect a first portion (100a) extended in one direction and a second portion (100b) extended in a direction orthogonal to the one direction.

[0124] The two sealing members (1000) are joined to each other at a connecting part (100d), and the connecting part (100d) has a shape of both ends having a cross-section identical to the cross-sections of the first part (100a) and the second part (100b) so as to enable continuous connection with each part.

[0125] Accordingly, the sealing member (1000) extends without discontinuity in cross-sectional shape based on the connection portion (100d), and the sealing performance and mechanical properties are maintained substantially the same before and after the connection portion (100d).

[0126] By this connection structure, the sealing member (1000) can be configured to function as a single continuous sealing member (1000) while having multiple extension directions.

[0127] The cross-sectional shape of the sealing member (1000) is applied to the above connecting part (100d), and an auxiliary sealing part (223) may be further formed in the cover sealing part (220).

[0128] Referring to FIG. 13, the cross-sectional shape of the portion where the auxiliary sealing portion (223) is formed in the connection portion (100d) has a shape that is extended longer than other portions where the auxiliary sealing portion (223) is not formed.

[0129] Although it also serves to assist in the sealing of the auxiliary sealing part (223), its primary function is to secure space so that another sealing member (1000) inserted into the side of the connecting part (100d) can be smoothly inserted into the interior. That is, the extended portion where the auxiliary sealing part (223) is formed is configured to improve assembly and mounting stability in a structure where multiple sealing members (1000) are applied together by performing the role of opening or guiding the insertion path of the other sealing member (1000).

[0131] The sealing member (1000) of the present invention may further include an end finishing portion (100e) at least at one end.

[0132] In one embodiment of FIG. 11, the end finishing portion (100e) may be formed at the end of the first portion (100a) and the end of the third portion (100c), respectively, and accordingly, end finishing portions (100e) may be included at both ends of the sealing member (1000).

[0133] The above end finishing portion (100e) is formed such that the ends of the insertion sealing portion (300) and the cover sealing portion (220) protrude toward the side of the door (2100), and has a shape in which the protrusion length toward the side of the door (2100) gradually increases as it moves away from the base portion (100).

[0134] Due to this shape, the end finishing portion (100e) is formed in a shape that gradually extends outward from the end region of the sealing member (1000).

[0135] Referring to FIG. 14, an insertion protrusion (224) that protrudes sharply in a triangular shape may be formed on the end end portion (100e).

[0136] The insertion protrusion (224) is formed so that when the end end portion (100e) is combined with the connecting portion (100d) formed at an adjacent position, it can be fully inserted into the internal space of the connecting portion (100d).

[0137] That is, the insertion protrusion (224) serves to guide the end finishing portion (100e) to naturally flow into the interior of the connecting portion (100d) without interfering with the outside of the connecting portion (100d) during the process of the end finishing portion (100e) engaging with the adjacent connecting portion (100d).

[0138] Through this, the connection between the end finishing portion (100e) and the connecting portion (100d) can be made more stably.

[0139] According to FIG. 15, in the area where the end finishing portion (100e) is formed, the cover sealing portion (220) is formed such that the cross-sectional thickness gradually decreases toward the end.

[0140] According to FIG. 16, this cross-sectional thickness reduction shape is intended to allow the insertion protrusion (224) to be smoothly inserted into the interior of the connecting part (100d) when the end finishing part (100e) overlaps and is joined with the adjacent connecting part (100d) during the process of closing the door (2100) from an open state.

[0141] In this way, the cross-sectional thickness of the insertion protrusion (224) formed on the end end portion (100e) and the cover sealing portion (220) that decreases toward the end minimizes interference during the process of the end end portion (100e) being joined to the adjacent connecting portion (100d) and induces the insertion protrusion (224) to be stably inserted into the connecting portion (100d).

[0142] As a result, curling, entanglement, or abnormal deformation of the end of the sealing member (1000) during the opening and closing process of the door (2100) is prevented, and the bonding stability and durability of the entire sealing member (1000) are improved.

[0144] FIG. 17 is a schematic diagram showing one embodiment of a sealed door (2000) to which the sealing member (1000) of the present invention is applied, and a storage space (3000) including the sealed door (2000).

[0145] Referring to FIG. 17, the sealing door (2000) includes a door (2100) formed to be openable and closable, and sealing members (1000) in the shape of a 'C' and a 'M' arranged along the upper, side and lower surfaces of the door (2100).

[0146] The insertion sealing portion (300) and the cover sealing portion (220) of the sealing member (1000) are formed to extend in the same direction with respect to the base portion (100), and accordingly, the sealing member (1000) is positioned to perform a sealing function toward the outside of the door (2100).

[0147] Meanwhile, the door (2100) is coupled to one side of the base (100) where the insertion sealing portion (300) and the cover sealing portion (220) are not formed, and the base (100) is fixed along the edge area of ​​the door (2100).

[0148] Additionally, the cover fixing part (210) is formed to be positioned adjacent to the front surface (2100a) of the door (2100), and supports the cover sealing part (220) between the opposing member (Om) when the door (2100) is closed, and performs the role of securing the structural stability of the entire sealing member (1000).

[0149] Accordingly, the sealing performance of the above-mentioned sealing door (2000) is improved in the front direction of the door (2100).

[0150] When a plurality of sealed doors (2000) are arranged, a sealing member (1000) is arranged along the edge of each door (2100), and sealing is also performed between adjacent doors (2100) by an insertion sealing part (300) and a cover sealing part (220).

[0151] In this case, any one of the adjacent doors (2100) can function as a facing member (Om) to another door (2100).

[0152] Meanwhile, the above-mentioned sealed door (2000) can be applied to a storage space (3000) in which an internal space is formed by a frame (3100).

[0153] The storage space (3000) comprises a frame (3100) and a sealing door (2000) that is openably coupled to the frame (3100) as an opposing member (Om), and each sealing door (2000) includes a 'U'-shaped sealing member (1000) to block the inside and outside of the storage space (3000). As a result, the storage space (3000) has a sealed structure that effectively blocks the inflow of outside air, moisture, or foreign substances.

[0155] The present invention has been described in more detail above through drawings and embodiments. However, the configurations described in the drawings or embodiments described in this specification are merely one embodiment of the present invention and do not represent all technical concepts of the present invention; therefore, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.
