Then, as shown by the alternate long and short dash arrow in FIG. 2, the door body 2 is rotated rearward to come into contact with the frame body 3 (specifically, the packing 6 provided on the door body 2 to be described later is attached to the frame body 3). The opening 10a is closed. The opening / closing operation and the sealing operation of the door body 2 are manually performed by the user holding the handle 5.

In the present embodiment, of the left and right sides of the door 1, the left side in the front view, which is the side where the hinge 4 is provided, is described as the "hanging source side", and the right side opposite to the hanging source side is the "door". "First side" is described. Further, the front surface of the door body 2 is described as the front surface 2f, and the rear surface is described as the back surface 2r. As shown in FIG. 2, the door body 2 is provided so that the opening 10a of the wall body 10 can be opened and closed by opening one side.

A frame body 3 made of stainless steel is provided on the front surface of the wall body 10. In the frame body 3, three square tube members are arranged on the door end side, the hanging side, and the lower side, and are integrally joined so as to be orthogonal to each other. That is, the frame body 3 is configured in a substantially U shape when viewed from the front, and the upper side is open. It is also possible to provide the frame 3 on all four sides of the door 1. In the present embodiment, each square tube member is described as a door end side frame body 3a, a hanging source side frame body 3b, and a lower side frame body 3c. In the present embodiment, the state in which the door body 2 opens the opening 10a is described as the "open state" of the door 1, and the state in which the door body 2 is closed is described as the "closed state" of the door 1.

As shown in FIGS. 2 and 3, the door body 2 has a front side steel plate 21 provided on the side of the front surface 2f and a back side steel plate 22 provided on the side of the back surface 2r via a plurality of connecting members 23, 23, and so on. It is formed by joining. As shown in FIG. 2, the external dimensions of the back side steel plate 22 and the connecting members 23, 23, ... It is formed larger than the inner peripheral dimension of the frame 3 in the left-right direction.

In the present embodiment, as shown in FIGS. 2 and 3, the packing according to the present invention is provided on the peripheral edge portion (specifically, the left and right edge portions and the lower edge portion) of the rear surface of the front side steel plate 21 along the peripheral edge portion. A packing 6 which is an embodiment of the structure is provided. As shown in FIG. 2, the door 1 can be opened and closed by the peripheral edge portion of the door body 2 and the frame body 3 being close to or separated from each other. In the door 1 according to the present embodiment, packings 6 are provided on all of the peripheral portions of the door body 2 and the proximity portions of the frame body 3.

The object to which the packing 6 configured as the packing structure is provided is not limited to the door 1 shown in the present embodiment, and can be provided, for example, in an opening portion of a storage tool, a case, or the like. That is, even if it is provided on the first member (peripheral portion of the front side steel plate 21 in the present embodiment) and is sandwiched between the first member and the second member (frame body 3 in the present embodiment). For example, the packing structure according to the present invention can be adopted.

When the door body 2 closes the opening 10a, the rear surface of the peripheral edge portion of the front side steel plate 21 is close to the front surface of the frame body 3. At this time, the packing 6 comes into contact with the frame body 3, so that the watertightness of the door 1 is ensured. When the door body 2 closes the opening 10a, the back side steel plate 22 and the connecting members 23, 23, ... Are inserted inside the frame 3 as shown in FIG. It is also possible to provide the packing 6 in a predetermined portion in a portion close to the frame body 3, such as the lower half of the peripheral portion of the door body 2.

In the present embodiment, the packing 6 is provided on the rear surface of the front side steel plate 21 of the door body 2, but the packing 6 can also be provided on the front surface of the frame body 3. That is, when the door 1 is closed, the packing 6 may come into contact with the rear surface of the front steel plate 21 of the door body 2 to ensure watertightness (with respect to other embodiments described later). The same applies). In this case, since the packing 6 is always located near the passage (opening 10a), the packing 6 may be damaged due to contact between the luggage and the packing 6 when the luggage is carried in and out with the door 1 open. There is sex. Therefore, in the present embodiment, the packing 6 is provided on the door body 2. When the door body 2 is composed of a sliding door or the like in the door 1, it is preferable to provide the packing 6 on the frame 3 from the viewpoint of the ease of assembly and maintainability of the elastic member 62 described later.

The hanging side frame 3b and the hanging side end of the door body 2 are connected by two hinges 4 and 4 including a fixed hinge 4a and a movable hinge 4b. Specifically, the fixing hinge 4a of the hinge 4 is attached to the hanging side frame 3b by a fixing tool such as a bolt. Further, a movable hinge 4b of the hinge 4 is attached to the hanging side end portion of the surface 2f of the door body 2 by a fixing tool such as a bolt. As a result, the door body 2 is rotatably assembled to the frame body 3 in the front-rear direction around the hinges 4 and 4.

In the door 1 according to the present embodiment, the sealing mechanism 7 for bringing the door body 2 into close contact with the frame 3 is housed in the internal space of the door body 2. Specifically, as shown in FIG. 4, the sealing mechanism 7 includes a handle 5 (front side handle 5f and back side handle 5r) for driving the sealing mechanism 7, first to fourth joints 51a to 51d, and first to eighth. It is composed of bevel jacks 52a to 52h, first to eighth taper rods 53a to 53h, connecting shafts connecting them, and first to eighth pressure receiving pins 54a to 54h fixed to the frame body 3.

In this embodiment, a mechanism composed of a bevel jack, a taper rod, and a pressure receiving pin is referred to as a "unit mechanism". As shown in FIG. 4, the door 1 is provided with four unit mechanisms (first unit mechanism 7a to fourth unit mechanism 7d) on the door end side. Similarly, three unit mechanisms (fifth unit mechanism 7e to seventh unit mechanism 7g) are provided on the lower side, and one unit mechanism (eighth unit mechanism 7h) is provided on the suspension source side. For example, the first unit mechanism 7a is composed of a first bevel jack 52a, a first taper rod 53a, and a first pressure receiving pin 54a (the same applies to the second unit mechanism 7b to the eighth unit mechanism 7h).

The handle 5 is provided on the door end side of the door body 2, the front handle 5f projects forward from the front surface 2f of the door body 2, and the back handle 5r projects rearward from the back surface 2r of the door body 2. The front side handle 5f and the back side handle 5r are connected to each other inside the door body 2 so as not to rotate relative to each other. When the user rotates the front side handle 5f from the front side of the door body 2 to the closed side or the back side handle 5r from the rear side to the closed side, the connecting shaft connected to the handle 5 is rotated around the axis. Rotate to.

The rotation of the connecting shaft is transmitted to the first to eighth bevel jacks 52a to 52h via the first to fourth joints 51a to 51d and other connecting shafts. The first to eighth bevel jacks 52a to 52h apply the rotational force input from the connecting shaft, and the tips of the first to eighth taper rods 53a to 53h are attached to the outside of the door body 2 (door end side, lower side, and hanging side). ) And convert it into a force in the straight direction to be inserted into the frame 3.

As shown in FIGS. 5A and 5B, a tapered surface 55 is formed at the tip of the first tapered rod 53a. When the first tapered rod 53a is displaced toward the door end side and inserted into the door end side frame body 3a, the tapered surface 55 abuts on the first pressure receiving pin 54a as shown in FIG. 5 (b), and the tapered surface 55 presses the first pressure receiving pin 54a toward the front side (open side of the door body 2). Since the first pressure receiving pin 54a is fixed to the frame body 3, the first taper rod 53a receives the reaction force from the first pressure receiving pin 54a and is displaced to the rear side (closed side of the door body 2). As a result, a force is generated on the closed side with respect to the door body 2. Then, when the front steel plate 21 of the door body 2 and the frame body 3 are in close proximity to each other, the packing 6 is brought into close contact with the frame body 3 as shown in FIG. 5 (b). The second unit mechanism 7a to the eighth unit mechanism 7h are also configured in the same manner as the first unit mechanism 7a.

In the sealing mechanism 7 configured as described above, when the user rotates the handle 5 to the closing side, in each unit mechanism (first unit mechanism 7a to eighth unit mechanism 7h), the door body 2 is closed to the closing side. Force is generated. Then, when the front steel plate 21 of the door body 2 and the frame body 3 are in close contact with each other, the packing 6 comes into close contact with the frame body 3 and seals the opening 10a. When the user turns the handle 5 to the open side, the state in which the packing 6 is in close contact with the frame body 3 is eliminated, so that the closed state of the opening 10a by the door body 2 is released.

In the present embodiment, as shown in FIGS. 5 and 6, the packing 6 is composed of an elastic member 62 and a holding member 61 for holding the elastic member 62. The elastic member 62 is formed of an elastic material such as rubber into a long columnar shape. In the present embodiment, the packing 6 is continuously (seamlessly) provided with one elastic member 62.

In the present embodiment, the elastic member 62 has a perfect circular cross section perpendicular to the axial direction. It is possible to make the cross section of the elastic member 62 an elliptical shape instead of a perfect circular shape, but it is easy for the operator to assemble the elastic member 62 to the holding member 61 and high watertightness. From the viewpoint of ensuring, it is preferable that the cross section of the elastic member 62 has a perfect circular shape.

The holding member 61 is a pair of rod-shaped members assembled to the door body 2 along the peripheral edge of the rear surface of the front steel plate 21. As shown in FIGS. 5 and 6, the holding member 61 is configured by fixing two rod-shaped members at predetermined intervals. As a result, the holding member 61 is formed in a groove shape having an opening on the rear side. As shown in FIG. 6A, the rod-shaped members constituting the holding member 61 are formed so that the surfaces facing each other are inclined in the direction of approaching each other as the distance from the front steel plate 21 increases. As a result, the holding member 61 is formed so that the groove shape is narrowed toward the side of the opening.

An elastic member 62 is inserted into the groove shape of the holding member 61. At this time, the elastic member 62 is inserted into the groove shape of the holding member 61 by the operator pushing the elastic member 62 by hand. Although the holding member 61 is composed of two rod-shaped members in the present embodiment, it is also possible to configure the holding member with one member having a groove shape into which the elastic member 62 can be inserted.

As shown in FIG. 5A, the door 1 is in an open state where the peripheral edge of the front steel plate 21 and the frame 3 (door end frame 3a) are separated from each other, and the elastic member 62 only contacts the frame 3. In this state (see FIG. 6A), the elastic member 62 is not subjected to the compressive force from the front steel plate 21 and the frame 3. Such a state in which no compressive force is applied to the elastic member 62 is referred to as a “non-compressed state”. As shown in FIG. 6A, the opening width Lt of the opening of the holding member 61 is formed to be smaller than the diameter D of the elastic member 62 in the uncompressed state. Therefore, the elastic member 62 does not separate from the holding member 61 unless it is forcibly pulled out. When the cross section of the elastic member 62 is elliptical, the opening width Lt is formed to be smaller than the minimum diameter (minor diameter of the ellipse) of the elastic member 62 in order to prevent the elastic member 62 from detaching from the holding member 61. It should be done.

As shown in FIG. 5A, the door 1 in which the peripheral edge portion of the front steel plate 21 and the frame body 3 are separated from each other is in an open state (as shown in FIG. 6A, the elastic member 62 is in contact with the frame body 3 and is not compressed. In the state), a part of the elastic member 62 extends from the opening of the holding member 61. Then, as described above, when the front steel plate 21 of the door body 2 and the frame body 3 are in close proximity to each other by the sealing mechanism 7 and the door 1 is closed, the elastic member 62 has the frame body 3 as shown in FIG. 6 (b). Is pushed toward the side of the holding member 61. At this time, there is a gap between the frame body 3 and the holding member 61 (a part of the elastic member 62 extends from the opening of the holding member 61).

At this time, the elastic member 62 is pressed by the frame body 3 and the peripheral edge portion of the front side steel plate 21, and widens in a direction orthogonal to the pressing direction (front-back direction) as shown in FIG. 6B. As described above, a state in which a compressive force is applied to the elastic member 62 from the peripheral portion of the frame body 3 and the front side steel plate 21 when the door 1 is closed by the sealing mechanism 7 is described as a “first compression state”. do. As shown in FIG. 6B, the maximum width dimension when the elastic member 62 is in the first compressed state (the width dimension of the substantially central portion of the elastic member 62 in the front-rear direction in the first compressed state) is the first dimension S1. And.

In the door 1 according to the present embodiment, as shown in FIG. 6B, the holding member 61 is an inner side surface 61a of a portion (position in the front-rear direction) where the elastic member 62 becomes the first dimension S1 when the elastic member 62 is in the first compressed state. The width dimension L1 is formed to have a size equal to or larger than the first dimension S1 (L1 ≧ S1).

According to the door 1 according to the present embodiment, when the door 1 is closed by the sealing mechanism 7 and the elastic member 62 is in the first compression state as described above, the elastic member 62 is the inner surface 61a of the holding member 61. Will not be pressed against. Therefore, the reaction force from the elastically deformed elastic member 62 can be concentrated and received by the peripheral edge portion of the front side steel plate 21 and the frame body 3. That is, since the adhesiveness between the elastic member 62 and the peripheral edge portion of the front steel plate 21 and the frame body 3 can be maintained high, it is possible to maintain high watertightness.

Further, according to the door 1 according to the present embodiment, the elastic member 62 can be held by the holding member 61 only by press-fitting the elastic member 62 into the holding member 61. That is, the door 1 can eliminate the need for an adhesive or the like for holding the elastic member 62. Therefore, according to the door 1, the poor adhesive quality and the deterioration of the watertightness due to the aged deterioration of the adhesive do not occur. Further, even when the elastic member 62 is replaced for maintenance of the door 1, the elastic member 62 can be removed from the door body 2 by pulling out the elastic member 62 from the holding member 61, so that the adhesive remains. There is no such thing. Therefore, when the new elastic member 62 is assembled to the holding member 61, the elastic member 62 and the door body 2 (or the frame body 3) can be brought into close contact with each other without a gap, so that the watertightness of the door 1 is high. It can be restored to the state.

In the door 1 according to the present embodiment, when water W collects in front of the door 1 as shown in FIG. 3, the door body 2 receives a pressing force in the direction of the frame 3 due to the water pressure. As a result, the elastic member 62 is further pressed by the peripheral portion of the frame body 3 and the front side steel plate 21 to be elastically deformed, so that the frame body 3 comes into contact with the holding member 61. In the present embodiment, the state in which the door body 2 is pressed and the frame body 3 and the holding member 61 come into contact with each other is referred to as a “pressing state”.

Further, the elastic member 62 is further widened in a direction orthogonal to the pressing direction (front-back direction) as shown in FIG. 6 (c). In this way, when the door 1 receives pressure from water, the frame body 3 comes into contact with the holding member 61, so that a compressive force is further applied to the elastic member 62 from the peripheral portions of the frame body 3 and the front side steel plate 21. The added state is described as "second compressed state". As shown in FIG. 6C, the maximum width dimension when the elastic member 62 is in the second compressed state (the width dimension of the substantially central portion of the elastic member 62 in the front-rear direction in the second compressed state) is the second dimension S2. And. As shown in FIGS. 6 (b) and 6 (c), the second dimension S2 is larger than the first dimension S1.

In the door 1 according to the present embodiment, as shown in FIG. 6 (c), the holding member 61 is an inner surface 61a of a portion (position in the front-rear direction) where the elastic member 62 becomes the second dimension S2 when the elastic member 62 is in the second compressed state. The width dimension L2 is formed to have a size equal to or larger than the second dimension S2 (L2 ≧ S2).

According to the door 1 according to the present embodiment, even when the door 1 receives the pressure from water and the elastic member 62 is in the second compressed state as described above, the elastic member 62 is attached to the inner surface 61a of the holding member 61. It will not be pressed. Therefore, the reaction force from the elastically deformed elastic member 62 can be concentrated and received by the peripheral edge portion of the front side steel plate 21 and the frame body 3. That is, even when the door 1 receives a large water pressure, it is possible to maintain high adhesion between the elastic member 62 and the peripheral edge portion of the front steel plate 21 and the frame body 3, so that high watertightness can be maintained.

In the door 1 according to the present embodiment, packings 6 are provided on the peripheral edges of the front steel plate 21 on all of the left and right edges and the lower edges that are close to the frame 3. Further, the packing 6 is provided with one elastic member 62 seamlessly and continuously. As a result, the peripheral portion of the front side steel plate 21 and the frame body 3 can be sealed by one elastic member 62 in the packing 6, and higher watertightness can be ensured in the door 1. In the door 1 according to the present embodiment, the frame body 3 is formed in a substantially U shape when viewed from the front, and is not annular, so that the seam of the elastic member 62 can be eliminated. However, it is also possible that the door 1 includes the frame body 3 on all four sides. In this case, the elastic member 62 is joined at one place or a plurality of places.

In the door 1 according to the present embodiment, the packing 6 is continuously provided with the holding member 61. That is, the holding member 61 is provided without a gap between both ends of the packing 6. This prevents the elastic member 62 from being completely exposed at the door 1. That is, by enhancing the protective property of the elastic member 62, higher watertightness can be ensured in the door 1. It is also possible to provide the holding member 61 intermittently or not to provide the holding member 61 at the corner of the door body 2.

<Another Embodiment>
The structure of the packing (holding member) is not limited to the above-mentioned first embodiment, and other embodiments shown in FIGS. 7 (a) to 7 (d) can be used. That is, the holding member may be formed so that the width dimension of the inner surface of the portion where the elastic member 62 becomes the first dimension S1 when the elastic member 62 is in the first compressed state is formed so as to be equal to or more than the first dimension S1. The part of can be of any shape. In any of the following embodiments, the elastic member 62 is held by being inserted into the groove shape of the holding members 161 to 461.

Specifically, as in the packing 106 according to the second embodiment shown in FIG. 7A, the cross-sectional shape of the holding member 161 can be a parallelogram. Further, it is also possible to make the shape of the inner surface of the holding member 261 a curved surface as in the packing 206 according to the third embodiment shown in FIG. 7 (b). Further, as in the packing 306 according to the fourth embodiment shown in FIG. 7 (c), the inner peripheral shape of the holding member 361 may be a shape in which the central portion in the front-rear direction is recessed. Further, as in the packing 406 according to the fifth embodiment shown in FIG. 7 (d), a plate member 462 is provided on the rear surface of the rod-shaped holding member 461, and the plate member 462 forms a narrow portion for narrowing the width dimension of the groove shape. It is also possible. That is, the narrow portion between the plate members 462 is formed as an opening.

Also in these other embodiments, when the door is closed by the sealing mechanism and the elastic member 62 is in the first compression state, the elastic member 62 is not pressed against the inner peripheral surface of the holding member. Therefore, the reaction force from the elastically deformed elastic member 62 can be concentrated and received by the peripheral edge portion of the front side steel plate 21 and the frame body. That is, since the adhesiveness between the elastic member 62 and the peripheral edge portion of the front steel plate 21 and the frame body can be maintained high, it is possible to maintain high watertightness.

Further, even in the door according to the other embodiment, the elastic member 62 can be held only by press-fitting the elastic member 62 into each holding member. That is, since an adhesive or the like for holding the elastic member 62 is not required, high watertightness can be ensured as in the door 1 according to the first embodiment.
