[0001] The present invention relates to a packing provided at a door stop of a door and a door device including the same.

Background Art

[0002] Conventionally, in a door frame of a door that requires airtightness and sound insulation, such as a toilet door, a door stop is provided not only on the vertical frame on the door tip side but also on the vertical frame on the door bottom side and the upper frame. Further, a packing is attached to the door stop so that the airtightness and sound insulation between two rooms separated by the door are ensured.

[0003] However, the packing provided at the door stop of the vertical frame on the door bottom side may be damaged by being pinched by the corner portion on the door bottom side of the door when the door is opened and closed. Therefore, after chamfering the corner portion on the door bottom side of the door, a sound insulation structure of the door has been proposed in which the size of the packing on the door bottom side is reduced so that the packing is not pinched by the corner portion on the door bottom side of the door (see, for example, Patent Document 1 below).

[0004] In the above sound insulation structure, packings are attached not only to the door stop but also to the frame body. The packing attached to the door stop abuts against the rear surface on the door stop side of the door in the closed position, and the packing attached to the frame body is provided so as to abut against the chamfered surface of the door in the closed position. With such a configuration, in the above sound insulation structure, the gap between the door and the door frame is sealed by two packings, and an air layer is formed by surrounding the two packings, the door, and the door stop, thereby ensuring sufficient airtightness and sound insulation.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the soundproofing structure for doors described in Patent Document 1 requires chamfering the corners of the door and installing two gaskets. Furthermore, the gaskets attached to the frame itself must be installed on-site, making the installation time-consuming. In addition, even if the corners on the door's tail end are chamfered, a corner, though not sharp, is still formed at the edge of the chamfered surface. This corner can slightly gouge the gasket, potentially causing further damage.

[0007] The present invention has been made in view of the above, and its purpose is to provide a door gasket for the trailing edge of a door that is excellent in airtightness, easy to install, and durable, and that is not gouged by the corners of the door, and a door device using the same. [Means for solving the problem]

[0008] To achieve the above objective, the present invention provides a gasket attached to the door stopper of the door-side vertical frame, which contacts the door-side end face of the door when it is in the closed position, and is configured to deform and make surface contact with the door-side end face of the door when it comes into contact with it.

[0009] Specifically, the first invention is based on a vertical frame body that is attached to the door end of an opening in an interior wall and extends vertically, and a door stopper that is attached to the inner surface of the vertical frame body and extends vertically in correspondence with the vertical frame body, and a packing that is attached to the door stopper and extends vertically in correspondence with the door stopper.

[0010] The first invention is characterized by comprising: a curved surface portion having a cross-section that bulges toward the leading edge of the door in the width direction of the door; and a support portion provided outside the opening and closing area of ​​the door, continuous with the curved surface portion and extending rearward toward the door stop, with its rear end fixed to the front surface of the door stop on the door side, and supporting the curved surface portion so as to be pressed against a portion of the door end face other than the corner of the door tail end face when the door is in the closed position, wherein the curved surface portion is configured to make surface contact with the door tail end face of the door in the closed position by being pressed against it.

[0011] In the first invention, a vertically extending packing to be attached to the door stop on the door-end vertical frame is configured to include a curved surface portion having a cross-section that bulges toward the door-end side in the width direction of the door, and a support portion that is provided outside the door opening and closing area and supports the curved surface portion so as to be pressed against a portion of the door-end end face other than the corner when the curved surface portion is in the closed position. When such a packing is attached to the door stop on the door-end vertical frame, when the door is closed, the gap between the door and the door frame on the door-end side is firmly sealed by the packing, which extends from the door-end end face to the front of the door stop while making surface contact with the door-end end face of the door. Furthermore, since both the curved surface portion and the support portion of the packing are positioned so as not to be gouged by the corner of the door during the opening and closing operation of the door, there is no risk of damage. Moreover, since the packing is fixed to the door stop on the door-end vertical frame, if a door stop with the packing already fixed is installed, the packing will also be installed. Therefore, according to the first invention, it is possible to provide a door gasket that is highly airtight, easy to install, and durable, and that is not gouged by the corners of the door.

[0012] The second invention is characterized in that, in the first invention, the curved surface portion and the support portion are integrally molded from resin.

[0013] In the second invention, the packing is a single molded resin product. Therefore, according to the second invention, a door end packing that is highly airtight, easy to install, and durable, and not gouged by the corners of the door, can be easily manufactured.

[0014] The third invention is characterized in that, in the second invention, the support portion is continuous with the front end of the curved surface portion and extends backward by folding back toward the main body of the vertical frame portion toward the curved surface portion.

[0015] In the third invention, the packing is configured to have a J-shaped cross-section. According to the third invention, it is possible to provide a door-end packing that is highly airtight, easy to install, and highly durable, without requiring a complex shape, and with a simple configuration, and that is not gouged by the corners of the door.

[0016] The fourth invention is characterized in that, in the third invention, the support portion is configured to abut against the inner surface of the vertical frame body when the door is in the closed position, and to press the curved surface portion against the door-side end face of the door in the closed position.

[0017] In the fourth invention, the packing is configured such that when the door is in the closed position, the support portion abuts against the inner surface of the vertical frame body, pressing the curved surface portion against the trailing end face of the door in the closed position. With a packing configured in this way, when the door is closed, the curved surface portion of the packing is firmly pressed against the trailing end face of the door, making it easier to maintain airtightness when the door is closed. Therefore, according to the fourth invention, it is possible to provide a door trailing end packing with superior airtightness.

[0018] The fifth invention is characterized in that, in the second invention, the support portion is continuous with the rear end of the curved surface portion and extends rearward so as it approaches the door stop, it approaches the vertical frame body.

[0019] In the fifth invention, the packing is configured to have a U-shaped cross-section. According to the fifth invention, without having a complex shape, it is possible to provide a packing on the door jamb side of the door that has excellent airtightness, is easy to install, and has excellent durability without being pinched by the corners of the door with a simple configuration.

[0020] The sixth invention is characterized in that, in the fifth invention, the curved surface portion is configured such that when the door is in the closed position, the front end abuts against the inner surface of the vertical frame body.

[0021] In the sixth invention, the curved surface portion is supported by the support portion so as to be pressed against the end surface on the door jamb side of the door in a state where the front end abuts against the inner surface of the vertical frame body when the door is closed. According to the packing having such a configuration, when the door is closed, the curved surface portion of the packing is firmly pressed against the end surface on the door jamb side of the door, so that airtightness is easily maintained when the door is closed. Therefore, according to the sixth invention, it is possible to provide a packing on the door jamb side of the door that has more excellent airtightness.

[0022] The seventh invention is a door device including at least a vertical frame on the door leading side, an upper frame, and a vertical frame on the door jamb side as a frame body, a door frame attached to an opening of an indoor wall, a door attached to the door frame so as to be openable and closable, and a packing attached to the door contact of each frame body of the door frame, the packing attached to the door contact of the vertical frame on the door jamb side of the door frame is the packing according to any one of the first to sixth inventions.

[0023] In the seventh invention, by attaching the packing according to any one of the first to sixth inventions to the door contact of the vertical frame on the door jamb side, it is possible to provide a door device that has excellent airtightness, is easy to install, and has excellent durability.

Advantages of the Invention

[0024] As described above, according to the present invention, a packing that abuts against the door-end side end face of a door in a closed position is attached to the door-stop side vertical frame at the door-stop, and when the packing abuts against the door-end side end face of the door, it is configured to deform and make surface contact. Therefore, it is possible to provide a packing on the door-end side of a door that is excellent in airtightness, easy to install, and has excellent durability not to be pinched by the corners of the door, and a door device using the same.

Embodiments for Carrying Out the Invention

[0026] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. The description of the following embodiments is merely illustrative in nature and is not intended to limit the present invention, its applications, or its uses in any way.

[0027] 《Embodiment 1 of the Invention》 -Configuration of the Door Device- Figure 1 is a front view of a door device 100 in which a packing (third packing 33) according to Embodiment 1 of the present invention is applied to the door edge, and Figure 2 is a cross-sectional view of the door device 100. For the sake of explanation, in the following, the left side, right side, top side, and bottom side of Figure 1 will be referred to as "left," "right," "top," and "bottom," respectively, and the side closer to the viewer in the direction perpendicular to the plane of Figure 1 will be referred to as "front" and the side further away will be referred to as "back."

[0028] As shown in Figures 1 and 2, the door device 100 is installed in the opening 2 of the wall 1. The opening 2 is the part of the wall 1 that defines (borders) a rectangular opening when viewed from the front. The wall 1 is a large wall structure in which multiple wall base materials 5, ..., 5 are installed on both the front and rear sides of the wall frame 1, which consists of columns 3 and lintels 4. The door device 100 comprises a door frame 10, a door 20, and first to third packings 31 to 33. The door frame 10 of the door device 100 is attached to the opening 2.

[0029] (Door frame) The door frame 10 is attached to the inner surface of the opening 2 (the end surface of the wall 1 that defines the rectangular opening). In this embodiment 1, spacers 6 are attached to the inner surface (opening side) of the wall 1's structure (columns 3, 3 and lintel 4), and the door frame 10 is attached to the opening 2 including the spacers 6.

[0030] As shown in Figures 1 and 2, the door frame 10 is a three-sided frame comprising a leading-edge vertical frame (frame body) 11 attached to the left inner surface of the opening 2, an upper frame (frame body) 12 attached to the upper inner surface of the opening 2, and a trailing-edge vertical frame (frame body) 13 attached to the right inner surface of the opening 2.

[0031] The door-side vertical frame 11, the upper frame 12, and the door-side vertical frame 13 are basically composed of the same components. In the following description, items common to the door-side vertical frame 11, the upper frame 12, and the door-side vertical frame 13 will simply be referred to as frame bodies 11-13. Similarly, items common to the door-side vertical frame 11 and the door-side vertical frame 13 will simply be referred to as vertical frames 11 and 13. Frame bodies 11-13 include a frame body 14 and a door stop 15.

[0032] As shown in Figure 2, the frame body 14 of the vertical frames 11 and 13 is formed to have a symmetrical cross-sectional shape. The frame body 14 of the vertical frames 11 and 13 is a long, vertically extending wooden board-like member made of wood-based material such as wood, plywood, medium-density fiberboard, particleboard, or laminated wood, and in this embodiment 1, it has a substantially rectangular cross-section. The frame body 14 of the vertical frames 11 and 13 may also be made of resin or steel. A groove 14b is formed on the inner surface 14a of the frame body 14 of the vertical frames 11 and 13 into which a part of the door stopper 15 (leg portion 15b) is inserted. The groove 14b is formed from one end to the other (upper end to lower end) in the longitudinal direction of the frame body 14. The frame bodies 14 of the vertical frames 11 and 13 are positioned so that their outer surfaces abut against the inner surfaces of the spacers 6 fixed to the inner surface of the column 3, and are fixed to the column 3 via the spacers 6 using adhesive and nail-like members 16 such as nails, pin nails, or screws. The nail-like members 16 are driven towards the bottom of the groove 14b and are therefore hidden by the door stop 15.

[0033] As shown in Figure 3, the frame body 14 of the upper frame 12 is a long, horizontally extending wooden board-like member made of wood-based material such as wood, plywood, medium-density fiberboard, particleboard, or laminated wood, and in this embodiment 1, it has a substantially rectangular cross-section. The frame body 14 of the upper frame 12 may be made of resin or steel, similar to the frame bodies 14 of the vertical frames 11 and 13. A groove 14b is formed on the inner surface 14a of the frame body 14 of the upper frame 12 into which a part of the door stop 15 (leg portion 15b) is inserted. The groove 14b is formed from one end to the other (left end to right end) in the longitudinal direction of the frame body 14. The frame body 14 of the upper frame 12 is positioned so that its upper surface abuts against the inner surface of a spacer 6 fixed to the inner surface of the lintel 4, and is fixed to the lintel 4 via the spacer 6 by adhesive and nail-like members 16 such as nails, pin nails, or screws. The nail-shaped member 16 is driven into the bottom of the groove 14b and is therefore hidden by the door stop 15.

[0034] The door stopper 15 is a long member that extends along the frame body 14 of each frame 11 to 13 from one end to the other in the longitudinal direction of the frame body 14. As shown in Figures 2 and 3, the door stopper 15 has a main body portion 15a with a U-shaped cross-section and a pair of legs 15b, 15b that extend continuously and parallel to the end of the main body portion 15a. The door stopper 15 is installed so that the main body portion 15a protrudes inward from the inner surface 14a of the frame body 14 of each frame 11 to 13 by inserting the pair of legs 15b, 15b into grooves 14b formed in the inner surface 14a of the frame body 14. When the door 20 is in the closed position (when the door 20 is closed), the main body portion 15a covers the gap formed between the door 20 and the door frame 10 from the rear, thereby suppressing light leakage from the gap between the door frame 10 and the door 20. As will be explained in more detail later, each door 15 is fitted with first to third packings 31 to 33 to seal the gap between the door frame 10 and the door 20.

[0035] The pair of vertical frames 11 and 13 and the upper frame 12 are framed in a vertically dominant manner. Specifically, the left and right end faces (end faces) of the upper frame 12 are in contact with the inner surfaces of the pair of vertical frames 11 and 13, and the door frame 10 is constructed by driving nail-like members such as screws into both the vertical frames 11 and 13 and the upper frame 12.

[0036] (door) The door 20 is a hinged door and is pivotably attached to the frame body 14 of the door-end vertical frame 13 of the door frame 10 by upper and lower hinges 21, 21. The door 20 is fitted with a lever 22 for opening and closing operation.

[0037] (rubber seal) The first to third packings 31 to 33 are elongated members that extend from one end to the other in the longitudinal direction along the main body portion 15a of each door 15. The first to third packings 31 to 33 are injection-molded resin products. The first packing 31, which is attached to the door stop 15 of the door edge side vertical frame 11, and the second packing 32, which is attached to the door stop 15 of the upper frame 12, have the same cross-sectional shape, while the third packing 33, which is attached to the door stop 51 of the door tail side vertical frame 13, has a different cross-sectional shape from the first and second packings 31 and 32.

[0038] As shown in Figures 2 to 4, the first and second packings 31 and 32 have a curved cross-sectional shape. As shown in Figures 2 and 4, in a plan view, the first packing 31 has one end (rear end) fixed to the front surface of the main body 15a of the door stop 15 on the door edge side vertical frame 11, and extends diagonally forward from the fixed rear end toward the inner surface 14a (right side) of the frame body 14 of the door edge side vertical frame 11. As shown in Figure 3, in a plan view, the second packing 32 has one end (rear end) fixed to the front surface of the main body 15a of the door stop 15 on the upper frame 12, and extends diagonally forward from the fixed rear end toward the inner surface 14a (bottom surface) of the frame body 14 of the upper frame 12.

[0039] As shown in an enlarged view in Figure 4, when the door 20 is moved from the open position to the closed position (from the state shown in the upper part of Figure 4 to the state shown in the lower part of Figure 4), the front surface of the first packing 31 comes into contact with the rear surface of the door 20 in the closed position, thereby sealing the gap between the front surface of the door stop 15 of the door edge side vertical frame 11 and the rear surface of the door 20. In this embodiment 1, the first packing 31 is configured to be soft enough to deform when the rear surface of the door edge side end of the door 20 in the closed position is pressed against it, and to make surface contact with the rear surface of the door edge side end of the door 20 (see the lower part of Figure 4).

[0040] Similar to the first packing 31, when the door 20 is moved from the open position to the closed position, the second packing 32's front surface comes into contact with the rear surface of the door 20 in the closed position, thereby sealing the gap between the front surface of the door stop 15 of the upper frame 12 and the rear surface of the door 20. In this embodiment 1, the second packing 32 is configured to be soft enough to deform when the rear surface of the upper end of the door 20 in the closed position is pressed against it, and to make surface contact with the rear surface of the upper end of the door 20.

[0041] As shown in Figures 2 and 5, the third packing 33 comprises a curved surface portion 33a and a support portion 33b. The curved surface portion 33a has a cross-section that bulges toward the leading edge of the door 20 in the width direction of the door 20. In Embodiment 1, the curved surface portion 33a is formed so that its cross-section is arc-shaped. When the door 20 is moved from the open position to the closed position (from the state shown in the upper diagram of Figure 5 to the state shown in the lower diagram), the curved surface portion 33a abuts against the trailing edge end surface (right end surface) 20a of the door 20 in the closed position, thereby sealing the gap between the inner surface 14a (left surface) of the frame body 14 formed on the front side of the door stop 15 of the trailing edge vertical frame 13 and the trailing edge end surface 20a of the door 20. In this embodiment 1, the curved surface portion 33a is configured to be soft enough to deform when pressed against the door-side end surface 20a of the door 20 in the closed position, and to make surface contact with the door-side end surface 20a of the door 20.

[0042] The support portion 33b is located outside the opening and closing area of ​​the door 20. The support portion 33b extends backward toward the door stop 15 of the door-end vertical frame 13, continuous with the curved surface portion 33a, and its rear end is fixed to the front surface of the door stop 15. In this embodiment 1, the support portion 33b is continuous with the front end of the curved surface portion 33a, folds backward toward the frame body 14 side (right side) of the door-end vertical frame 13, and extends backward, having a J-shaped cross-section in plan view.

[0043] The support portion 33b supports the curved surface portion 33a so that it is pressed against the portion of the door-side end face 20a of the door 20 in the closed position, excluding the corner. Specifically, as shown in the upper part of Figure 5, when the door 20 is in the open position, the support portion 33b supports the curved surface portion 33a so that at least a part of it is located on the leading edge side (left side) of the door-side end face (right end face) of the door 20 in the closed position (see dashed line). By supporting the curved surface portion 33a in this way, when the door 20 is moved to the closed position, the curved surface portion 33a is pressed against the door-side end face 20a of the door 20 in the closed position, thereby making surface contact with the door-side end face 20a of the door 20 in the closed position.

[0044] Furthermore, in this embodiment 1, the third packing 33 is formed such that its maximum width (the maximum distance between the curved surface portion 33a and the support portion 33b in the width direction of the door 20) is greater than the distance between the tail end face 20a of the door 20 and the inner surface 14a of the frame body 14 of the tail-side vertical frame 13. Therefore, in this embodiment 1, when the door 20 is moved from the open position to the closed position (from the state shown in the upper diagram of Figure 5 to the state shown in the lower diagram), the curved surface portion 33a is pressed against the tail end face 20a of the door 20, and the support portion 33b is pressed against the inner surface 14a of the frame body 14 of the tail-side vertical frame 13.

[0045] -Door frame installation method- Next, we will explain the installation method for the door frame 10.

[0046] First, the frame bodies 11-13 are assembled to form the gate-shaped frame body 14 (framework process). Specifically, the frame body 14 of the upper frame 13 is placed between the upper ends of the frame bodies 14 of the left and right vertical frames 11 and 13, so that the left and right end faces (end faces) abut against the inner surfaces of the upper ends of the frame bodies 14 of the left and right vertical frames 11 and 13, and fixed with screws (not shown). In this way, the frame bodies 11-13 are assembled into a gate shape in a so-called vertically dominant arrangement.

[0047] After the framing process, the assembled gate-shaped frame body 14 is attached to the opening 2 (frame construction process). Specifically, the gate-shaped frame body 14 is placed inside the opening 2, spacers 6 are inserted between the frame body 14 of each frame 11-13 and the structure of the wall 1 (columns 3 and lintels 4), and screws or other nail-like members 16 are driven in from the inner surface 14a side of the frame body 14 of each frame 11-13 toward the opening 2 (end of the wall 1) to fix it in place.

[0048] After the frame construction process, door stops 15 are attached to the frame bodies 14 of the frame 11 to 13 (door stop installation process). Each door stop 15 is fixed to the frame body 14 by inserting the leg portion 15b, to which adhesive has been applied, into a groove 14b formed on the inner surface 14a of the frame body 14 of the corresponding frame 11 to 13, and allowing the adhesive to harden.

[0049] Before installing unit 15 for each unit, the first to third packings 31 to 33 are fixed to unit 15 for each unit. The first to third packings 31 to 33 are fixed with adhesive so that their rear ends are on the front surface of unit 15 for each unit.

[0050] The door stopper 15 with the first packing 31 fixed is inserted into the groove 14b of the frame body 14 of the door-side vertical frame 11 and fixed, the door stopper 15 with the second packing 32 fixed is inserted into the groove 14b of the frame body 14 of the upper frame 12 and fixed, and the door stopper 15 with the third packing 33 fixed is inserted into the groove 14b of the frame body 14 of the door-end vertical frame 13 and fixed. By fixing each door stopper 15 to the frame body 14 of the frame bodies 11 to 13 in this way, the first to third packings 31 to 33 are also installed in their predetermined positions along with the door stoppers 15, and the door frame 10 is completed.

[0051] Through the above steps, the door frame 10 is installed in the opening 2.

[0052] -The operation of the third gasket in conjunction with the opening and closing of the door- Next, we will explain the operation of the third packing 33, which is attached to the door stop 15 of the door-end vertical frame 13 of the door frame 10, in conjunction with the opening and closing of the door 20.

[0053] As shown in the upper part of Figure 5, when the door 20 is in the open position, the curved surface portion 33a is supported by the support portion 33b such that at least a part of the curved surface portion 33a is located on the leading edge side (left side) of the door end face (right end face) of the door 20 when it is in the closed position (see dashed line).

[0054] As the door 20 is closed from the open position (moved to the closed position), the tail end surface 20a of the door 20 comes into contact with the curved surface portion 33a. As the door 20 moves further, the curved surface portion 33a is pushed toward the frame body 14 side (right side) of the tail-side vertical frame 13. Consequently, the lower part of the support portion 33b corresponding to the curved surface portion 33a is also pushed toward the frame body 14 side (right side) of the tail-side vertical frame 13.

[0055] As the door 20 is moved to the closed position, the lower part of the support portion 33b contacts the inner surface 14a of the frame body 14 of the door-end vertical frame 13, and then the support portion 33b is pressed against the inner surface 14a of the frame body 14 of the door-end vertical frame 13. The support portion 33b, pressed against the inner surface 14a of the frame body 14 of the door-end vertical frame 13, deforms so that the width of the J shape in plan view becomes smaller (the curvature becomes larger), and the curved surface portion 33a is pressed against the door-end end surface 20a of the door 20.

[0056] As a result, as shown in the lower diagram of Figure 5, when the door 20 reaches the closed position, the curved surface portion 33a is pressed against the door-side end face 20a of the door 20 and makes surface contact with the door-side end face, and the support portion 33b is pressed against the inner surface 14a of the frame body 14 of the door-side vertical frame 13 and makes surface contact with the inner surface 14a of the frame body 14. In this way, the curved surface portion 33a makes surface contact with the door-side end face 20a of the door 20 in the closed position, so that the third packing 33 extends from the front surface of the door stop 15 of the door-side vertical frame 13 to the door-side end face 20a of the door 20 in the closed position, and the gap between the inner surface 14a of the frame body 14 formed on the front side of the door stop 15 of the door-side vertical frame 13 and the door-side end face 20a of the door 20 is sealed by the third packing 33.

[0057] Furthermore, the curved surface portion 33a of the third packing 33 is pressed against a portion of the door-side end face 20a of the door 20 in the closed position, excluding the corner, while the support portion 33b is positioned outside the opening and closing range of the door 20. Therefore, during the opening and closing operation of the door 20, neither the curved surface portion 33a nor the support portion 33b comes into contact with the rear corner of the door-side end of the door 20, and the third packing 33 is not gouged by the rear corner of the door-side end of the door 20.

[0058] -Effects of Embodiment 1- In this embodiment 1, the third packing 33, which extends vertically and is attached to the door stopper 15 of the door-side vertical frame 13, is configured to include a curved surface portion 33a having a cross-section that bulges toward the door-edge side of the door 20 in the width direction of the door 20, and a support portion 33b that is provided outside the opening and closing area of ​​the door 20 and supports the curved surface portion 33a so as to be pressed against the part of the door-side end face 20a of the door 20 other than the corner when the curved surface portion 33a is in the closed position. When such a third packing 33 is attached to the door stopper 15 of the door-side vertical frame 13, when the door 20 is closed, the gap between the door 20 and the door frame 10 on the door-side of the door 20 is firmly sealed by the third packing 33, which extends from the door-side end face 20a of the door 20 to the front surface of the door stopper 15 while making surface contact with the door-side end face 20a of the door 20. Furthermore, since both the curved surface portion 33a and the support portion 33b of the third packing 33 are positioned so as not to be gouged by the corners of the door 20 during opening and closing operations, there is no risk of damage. Moreover, since the third packing 33 is fixed to the door stop 15 of the door-end vertical frame 13, if the door stop 15 with the third packing 33 already fixed is installed, the third packing 33 will also be installed. Accordingly, according to this embodiment 1, it is possible to provide a door-end packing (third packing 33) for the door 20 that is excellent in airtightness, easy to install, and highly durable as it is not gouged by the corners of the door 20.

[0059] Furthermore, in this embodiment 1, the curved surface portion 33a and the support portion 33b of the third packing 33 are integrally molded from resin. In other words, the third packing 33 is an integrally molded resin product. Accordingly, according to this embodiment 1, a packing (third packing 33) on the tail end of the door 20 that is excellent in airtightness, easy to install, and highly durable and not gouged by the corners of the door 20 can be easily manufactured.

[0060] Furthermore, in this embodiment 1, the support portion 33b of the third packing 33 is continuous with the front end of the curved surface portion 33a, and is configured to have a J-shaped cross-section that folds back and extends rearward on the frame body 14 side of the door-end vertical frame 13 from the curved surface portion 33a. With this configuration, according to this embodiment 1, it is possible to provide a door-end packing (third packing 33) for the door 20 that is easy to install, has excellent airtightness, is easy to install, and has excellent durability that is not gouged by the corners of the door 20, without requiring a complex shape.

[0061] Furthermore, in this embodiment 1, the third packing 33 is configured such that when the door 20 is in the closed position, the support portion 33b abuts against the inner surface 14a of the frame body 14 of the door-end vertical frame 13, pressing the curved surface portion 33a against the door-end end surface 20a of the door 20 in the closed position. With this configuration of the third packing 33, when the door 20 is closed, the curved surface portion 33a of the third packing 33 is firmly pressed against the door-end end surface 20a of the door 20, making it easier to maintain airtightness when the door is closed. Therefore, according to this embodiment 1, it is possible to provide a door-end packing (third packing 33) for the door 20 that has superior airtightness.

[0062] Furthermore, in the door device 100 of this embodiment, the third packing 33 configured as described above is attached to the door stop 15 of the door-end vertical frame 13, thus providing a door device 100 that is highly airtight, easy to install, and highly durable.

[0063] Embodiment 2 of the Invention Embodiment 2 of the present invention is a modification of the configuration of the third packing 33 in the door device 100 of Embodiment 1.

[0064] As shown in Figure 6, in Embodiment 2 as well, the third packing 33 includes a curved surface portion 33a and a support portion 33b. The curved surface portion 33a has a cross-section that bulges toward the door edge side of the door 20 in the width direction of the door 20. In Embodiment 2, the curved surface portion 33a is formed so that its cross-section is in the shape of a V. When the door 20 is moved from the open position to the closed position (from the state shown in the upper diagram of Figure 6 to the state shown in the lower diagram), the curved surface portion 33a abuts against the door edge end surface 20a of the door 20 in the closed position, thereby sealing the gap between the inner surface 14a of the frame body 14 formed on the front side of the door stop 15 of the door edge vertical frame 13 and the door edge end surface 20a of the door 20. In Embodiment 2 as well, the curved surface portion 33a is configured to be soft enough to deform when the door edge end surface 20a of the door 20 in the closed position is pressed against it, and to make surface contact with the door edge end surface 20a of the door 20.

[0065] In Embodiment 2, the support portion 33b is also provided outside the opening and closing area of ​​the door 20. The support portion 33b extends backward toward the door stop 15 of the door-end vertical frame 13, continuous with the curved surface portion 33a, and its rear end is fixed to the front surface of the door stop 15. In Embodiment 2, the support portion 33b extends backward toward the frame body 14 of the door-end vertical frame 13, as it approaches the door stop 15, and its rear end is fixed to the front surface of the door stop 15.

[0066] In Embodiment 2, the support portion 33b supports the curved surface portion 33a such that the curved surface portion 33a is pressed against the portion of the door-side end face 20a of the door 20 in the closed position, excluding the corner. Specifically, as shown in the upper part of Figure 6, when the door 20 is in the open position, the support portion 33b supports the curved surface portion 33a such that at least a part of the curved surface portion 33a is positioned on the leading edge side (left side) of the door-side end face (right end face) of the door 20 in the closed position (see dashed line). By supporting the curved surface portion 33a in this way, when the door 20 is moved to the closed position, the curved surface portion 33a is pressed against the door-side end face 20a of the door 20 in the closed position, thereby making surface contact with the door-side end face 20a of the door 20 in the closed position.

[0067] Furthermore, in Embodiment 2, the curved surface portion 33a of the third packing 33 is configured such that when the door 20 is in the closed position, its front end abuts against the inner surface 14a of the frame body 14 of the door-end vertical frame 13. Thus, in Embodiment 2, when the door 20 is moved from the open position to the closed position, the curved surface portion 33a abuts against the door-end end surface 20a of the door 20, causing the third packing 33 to move toward the frame body 14 side (right side) of the door-end vertical frame 13, and the front end of the curved surface portion 33a abuts against the inner surface 14a of the frame body 14. Then, due to the reaction force of the front end of the curved surface portion 33a being pressed against the inner surface 14a of the frame body 14, the top of the curved surface portion 33a (the part that protrudes to the left in Figure 6) is firmly pressed against the door-side end surface 20a of the door 20 and deformed, causing the curved surface portion 33a to make surface contact with the door-side end surface 20a of the door 20 over a relatively large area.

[0068] This second embodiment, with its configuration, can achieve the same effects as the first embodiment.

[0069] Furthermore, in Embodiment 2, the third packing 33, which is configured to have a V-shaped cross-section, can achieve the same effect as the third packing 33 in Embodiment 1. Therefore, according to Embodiment 2, it is possible to provide a packing (third packing 33) for the tail end of the door 20 that is easy to install, does not have a complex shape, has a simple configuration, is easy to install, and has excellent durability that prevents gouging by the corners of the door 20.

[0070] Furthermore, in Embodiment 2, the curved surface portion 33a is supported by the support portion 33b such that when the door 20 is closed, its front end abuts against the inner surface 14a of the frame body 14 of the door-side vertical frame 13 and is pressed against the door-side end surface 20a of the door 20. With the third packing 33 configured in this way, when the door 20 is closed, the curved surface portion 33a of the third packing 33 is firmly pressed against the door-side end surface 20a of the door 20, making it easier to maintain airtightness when the door is closed. Therefore, Embodiment 2 provides a door-side packing (third packing 33) for the door 20 that is more airtight.

[0071] Other embodiments The third packing 33 in Embodiments 1 and 2 described above is merely an example of a door-end packing according to the present invention, and the door-end packing according to the present invention is not limited to the third packing 33 in Embodiments 1 and 2. The packing comprises a curved surface portion 33a having a cross-section that bulges toward the door-edge side of the door 20 in the width direction of the door 20, and a support portion 33b provided outside the opening and closing area of ​​the door 20 so as to extend rearward toward the door stop 15, with its rear end fixed to the front surface of the door stop 15, and supporting the curved surface portion 33a so as to be pressed against the portion of the door-end end face 20a of the door 20 in the closed position other than the corner, and any form is acceptable as long as the curved surface portion 33a is pressed against the door-end end face 20a of the door 20 in the closed position so as to make surface contact with the door-end end face 20a of the door 20 in the closed position.

[0072] For example, the third packing 33 of Embodiment 1 shown in Figure 5 may be reversed left and right, and provided such that the support portion 33b is positioned outside the opening and closing area of ​​the door 20, and the support portion 33b moves closer to the frame body 14 of the door-end vertical frame 13 (away from the door 20) as it moves towards the rear in the front-rear direction.

[0073] Furthermore, the third packing 33 may have a cylindrical portion in a plan view, and a curved surface portion 33a may be formed by a part of the cylindrical portion. If it has a cylindrical portion, the support portion 33b may be provided so as to be connected to or continuous with the outer circumferential surface of the cylindrical portion.
