In this embodiment, the opening and closing direction of the sliding hatch cover coincides with the left-right direction and width direction of the ship. The length direction of the rain shelter for shipping coincides with the longitudinal direction and the length direction of the ship, and the width direction of the rain shelter for shipping coincides with the lateral direction and the width direction of the ship.

First, I will explain the ship loader and the ship. As shown in FIG. 1, a ship loader 1 includes a traveling portion 4 that travels on a rail 3 laid on a quay 2, a turning portion 5 that is rotatably provided on the traveling portion 4, and a rotating portion 5 that can be elevated. A freely provided boom 6 and a nozzle portion 8 suspended from the tip of the boom 6 for supplying cargo such as grain into a hold 7 are provided. The boom 6 is provided with a conveyor (not shown) for transferring cargo from the wharf 2 to the nozzle section 8 . It should be noted that cargo is not limited to grain. The load may also be other bulk items that do not like to get wet in the rain.

As shown in Figure 1, the ship 9 is a cargo ship. A ship 9 includes a hold 7 having an upper opening 10 and a sliding hatch cover 11 for opening and closing the upper opening 10 . A pair of sliding hatch covers 11 are provided on the left and right sides of the ship 9 so as to be slidable in the left and right direction. That is, the sliding hatch cover 11 is of a left and right double-opening type, and the upper opening 10 is closed by abutting the opposite ends 12 and the upper opening 10 is opened by separating the opposite ends 12 from each other. Also, the sliding hatch cover 11 is formed so as to open the upper opening 10 at arbitrary intervals. Hereinafter, an opening between the sliding hatch covers 11 formed by opening the sliding hatch covers 11 will be referred to as a hatch opening 13 . In addition, the sliding hatch cover 11 may be provided so as to be openable and closable in the longitudinal direction of the ship 9 .

Next, a rain protection device for shipping according to this embodiment will be described.

As shown in FIGS. 1 to 3, the shipping rain protection device 20 includes a device main body 20A configured to cover the hatch opening 13. As shown in FIGS. The apparatus main body 20A is arranged across the pair of sliding hatch covers 11 when the pair of sliding hatch covers 11 are opened, and covers the hatch opening 13. - 特許庁

The apparatus main body 20A includes a rail 19 arranged on the sliding hatch cover 11, a shipboard chute 22 provided on the rail 19 so as to be free to travel and covering a part of the hatch opening 13, and a lid covering the other part of the hatch opening 13. a member 23;

The rails 19 are arranged on the left and right sliding hatch covers 11 in parallel and extending in the front-rear direction. The rail 19 is configured by connecting a plurality of rail pieces 21 shorter than the longitudinal dimension of the hatch opening 13 in the longitudinal direction (front-rear direction). The length of the rail 19 is set so as to be approximately the same as the front-rear length of the hatch opening 13 when a predetermined number of rail pieces 21 are connected. Note that the rails 19 may not have a connecting structure. In this case, one rail piece 21 constitutes the rail 19 , and the length of the rail piece 21 is preferably set substantially equal to the length of the hatch opening 13 .

As shown in FIG. 2, the shipboard chute 22 includes a running portion 31 provided on the rail 19 so as to be free to run, and a substantially cylindrical chute body portion 32 into which the nozzle portion 8 is inserted. The traveling part 31 has a plurality of fixed casters. The fixed casters are common to the fixed casters 34 of the lid member 23 shown in FIG.

The nozzle portion 8 of the ship loader 1 is provided with a cover member 14 that covers the chute body portion 32 from above to prevent the cargo from getting wet.

The lid member 23 is formed to extend and contract in the front-rear direction, and is arranged in front of and behind the on-board chute 22 . One end of the lid member 23 in the front-rear direction is fixed to the shipboard chute 22 . The other end of the cover member 23 in the front-rear direction is detachably fixed to the rail 19 near the end of the hatch opening 13 . The cover member 23 expands and contracts according to the travel of the shipboard chute 22 . For example, as shown in FIGS. 5 and 6, when the on-board chute 22 is pushed by the nozzle portion 8 when the cargo B is supplied and the on-board chute 22 travels forward, the cover member 23 ahead of the on-board chute 22 moves forward. It contracts, and the lid member 23 behind the shipboard chute 22 extends forward.

The lid member 23 includes a plurality of bellows portions 69 that are formed to be stretchable in the front-rear direction, and a bellows support portion 70 that supports the bellows portions 69 .

The bellows portion 69 covers a plurality of arch frames 42 formed in an arch shape extending over the left and right rail pieces 21, an elastic link 43 connecting the arch frames 42 to each other so as to be close to each other in the front-rear direction. A waterproof sheet 41 is provided.

As shown in FIG. 7, the telescopic link 43 is configured by connecting a plurality of cross members 52 formed by connecting a pair of rod-shaped frames 50 via pins 51 in an X shape. The cross members 52 are connected to each other by connecting the ends of the rod-shaped frames 50 via the pins 51 . The ends of the cross member 52 are classified into a fixed end 52a fixed to the arch frame 42 and a movable end 52b slidably provided on the arch frame 42. As shown in FIG. The movable end 52b is rotatably connected to the slider 53 via the pin 51. As shown in FIG. The slider 53 is a tubular member and is slidably fitted to the arch frame 42 .

The waterproof sheet 41 is a flexible sheet, and can be deformed so as to expand and contract between the arch frames 42 .

As shown in FIGS. 2 and 8 , the bellows support part 70 is provided at the end of the bellows part 69 and formed in an arch shape extending over the pair of hatch covers 11 . The lower end of the bellows support portion 70 is also provided with fixed casters similar to those described above. A rain protection sheet 76 is provided on the bellows support portion 70 .

In addition, as shown in FIGS. 2 and 8, an end sheet 64 is provided on the bellows support portion 70 positioned at the other end of the lid member 23 . Thereby, the hatch opening 13 formed between the side surfaces of the sliding hatch cover 11 can also be closed.

By the way, there is a gap between the device main body 20A and the sliding hatch cover 11, and it is conceivable that rainwater may enter the hatch opening side through this gap. Specifically, the waterproof sheet 41 forming the outer skin of the bellows portion 69 in FIG. 4 deforms into a bellows shape. Therefore, there is a gap between the rail 19 and the waterproof sheet 41, and it is conceivable that rainwater may enter the hatch opening 13 through this gap. In addition, when the sliding hatch cover 11 and the rail 19 shown in FIG. It is conceivable that rainwater may infiltrate into

Therefore, as shown in FIGS. 4 and 9, the rain protection device 20 for shipping includes a water stop portion 100 that suppresses water from entering the hatch opening 13 side (right side) from the gap between the sliding hatch cover 11 and the device main body 20A. Prepare. The water stop part 100 is provided between a first seal 80 and a second seal 81 for suppressing wind and water from entering from between the rail 19 and the sliding hatch cover 11, and between the water stop sheet 41 and the rail 19. A water stop member 88 is provided.

Here, the rail 19 forms a base portion 20B which is provided on the device main body 20A and placed on the sliding hatch cover 11. As shown in FIG. The base 20B is positioned at the lowest end of the apparatus main body 20A and serves to support the weight of the upper portion of the apparatus main body 20A.

The water stop member 88 is composed of a brush and includes a brush head 89 and brush bristles 90 planted on the brush head 89 . Brush head 89 is supported on rail 19 via bracket 82 . The brush bristles 90 are made of resin, metal, animal hair, or the like. The tips of the brush bristles 90 are brought into contact with the inner surface of the waterproof sheet 41 . The waterproof member 88 is made of a brush and has air permeability. Thereby, the pressure in the hold 7 can be released. The waterproof member 88 may be made of a mesh-like soft resin sheet or the like. By providing a water stop member 88 consisting of a brush or the like in the gap between the rail 19 and the water stop sheet 41, the appropriately deformed brush or the like for the gap that changes due to the expansion and contraction of the water stop sheet 41 prevents entry of wind and water from the outside. can work to prevent

The first seal 80 is made of a relatively soft elastic material such as rubber and formed into a thin sheet with a constant thickness. A base end portion of the first seal 80 is supported by the rail 19 via a bracket 82 , and a tip end portion of the first seal 80 is overlapped with the upper surface of the slide type hatch cover 11 . The bracket 82 is formed to extend continuously in the extending direction (front-rear direction) of the rail 19, and extends to the opposite side of the hatch opening 13, that is, to the side opposite to the hatch opening (left side). A base end portion of the first seal 80 is attached to the inclined attachment surface 82 a of the bracket 82 with a bolt 91 . The middle portion of the first seal 80 is curved to accommodate the angular difference created between the proximal and distal ends. As a result, a force is generated in the intermediate portion in a direction to restore the shape of the first seal 80 , and this force presses the tip portion against the sliding hatch cover 11 . Brush head 89 is bolted to bracket 82 with common bolt 91 along with the proximal end of first seal 80 . As a result, the water stop member 88 and the first seal 80 are continuously connected, and water can be stopped from the sliding hatch cover 11 to the water stop sheet 41 .

The second seal 81 corresponds to a seal member in the claims, and constitutes a feature of this embodiment.

First, before describing the second seal 81 of the present embodiment, the second seal of the device of Patent Document 1 (referred to as a comparative example) will be described.

As shown in FIG. 17, in the comparative example, a lip seal 150 having a V-shaped cross section is used as the second seal. The lip seal 150 is made of an elastic material such as rubber, and is detachably attached to the bottom surface of the rail 19 .

Specifically, a metallic seal holder 151 is provided on the bottom surface of the rail 19, and the lip seal 150 is held by this seal holder 151. The seal holder 151 includes a mounting base 152 integrally attached to the bottom surface of the rail 19, and a pair of legs 154 detachably attached to the bottom surface of the mounting base 152 with bolts 153 and separated from each other. The pair of leg portions 154 hold the lip seal 150 between them and have

claws

155 and 156 that engage with the lip seal 150 . A third seal 157 is provided on the bottom surface of the pair of legs 154 .

However, with the configuration of the comparative example, when replacing the lip seal 150, the entire device must be laid down, making replacement relatively difficult. That is, the entire device is placed on its side, the bolts 153 are loosened, the pair of legs 154 are removed, and the lip seal 150 is removed. Then, a new lip seal 150 is attached in reverse order, and the entire device is raised and put back.

Therefore, in this embodiment, the second seal 81 is detachably attached to the side surface of the rail 19 as shown in FIG. The configuration of this embodiment will be described below with reference to FIG. 10 showing an enlarged main part.

FIG. 10(A) shows a natural state in which the rail 19 is not placed on the hatch cover 11 and the second seal 81 is not in contact with the hatch cover 11. FIG. FIG. 10(B) shows the state when the rail 19 is placed on the hatch cover 11 and the second seal 81 is in contact with the hatch cover 11 . At this time, the second seal 81 is bent from its natural state, and the second seal 81 is pressed against the hatch cover 11 by the reaction force of the bend, thereby performing sealing. In FIG. 10(C), although the rail 19 is basically placed on the hatch cover 11, a gap is formed between the rail 19 and the hatch cover 11 at the position shown due to deformation of the surface of the hatch cover 11 or the like. It shows a state in which the pressing of the second seal 81 against the hatch cover 11 is slightly weakened.

As illustrated, the second seal 81 is made of an elastic material such as rubber. The second seal 81 has a base end portion 101 detachably attached to a side portion 100 on the left side (opposite side of the hatch opening) of the rail 19, and a tip end portion extending downward from the base end portion 101 and in contact with the hatch cover 11. 102. A line a indicates the boundary position between the proximal end portion 101 and the distal end portion 102 . In particular, the thickness t of the distal end portion 102 gradually decreases from the base end side (upper side in the drawing) toward the distal end side (lower side in the drawing).

As shown in FIG. 9, the thickness of the first seal 80 is a relatively thin constant thickness ta. On the other hand, as shown in FIG. 10A, the thickness t of the tip portion 102 of the second seal 81 gradually decreases toward the tip side. This point is the main difference from the first seal 80 . The second seal 81 is arranged on the right side (hatch opening side) of the first seal 80 .

When the rail 19 is placed on the hatch cover 11, the second seal 81 generates surface pressure due to the reaction force received from the hatch cover 11, and exhibits an excellent waterproof function. Therefore, the shape of the second seal 81 is designed to appropriately generate surface pressure.

As shown in FIG. 10(A), the thickness tb of the base end portion 101 of the second seal 81 is a constant thickness greater than the thickness ta of the first seal 80 . Further, the thickness t of the distal end portion 102 of the second seal 81 is equal to the thickness tb of the proximal end portion 101 at the most proximal position where it is connected to the proximal end portion 101, and the thickness t increases toward the distal end side from this thickness tb. gradually decreased as The tip end portion 102 of the second seal 81 has a blade-like shape.

With this configuration, the second seal 81 has a so-called stiff structure, and can increase the surface pressure when it comes into contact with the hatch cover 11 as shown in FIG. 10(B).

A base end portion 101 of the second seal 81 is arranged in a direction perpendicular to the hatch cover 11 . That is, while the hatch cover 11 is arranged horizontally, the proximal end portion 101 of the second seal 81 is arranged vertically. As a result, the tip portion 102 can be efficiently pressed against the hatch cover 11, and the surface pressure when contacting the hatch cover 11 can be increased.

As shown in FIG. 10(A), the tip portion 102 of the second seal 81 is curved so that the tip side faces the left side (the side opposite to the hatch opening) in the natural state. As a result, as shown in FIG. 10B, when the leading end portion 102 contacts the hatch cover 11, the bending direction of the leading end portion 102 is specified, and at the same time as the rail 19 is placed on the hatch cover 11, the leading end portion 102 is bent. can be bent in any desired direction.

The second seal 81 is attached to the side portion 100 of the rail 19 via a bracket 103. The bracket 103 is fixed at a predetermined height position on the side portion 100 and horizontally extends leftward from the side portion 100 . A mounting surface portion 104 protruding downward is provided in the intermediate portion of the bracket 103 , and the base end portion 101 of the second seal 81 is superimposed on the left surface of this mounting surface portion 104 . A pressing plate 105 is superimposed on the left surface of the base end portion 101 . The pressing plate 105 and the base end portion 101 are aligned and fixed to the mounting surface portion 104 by bolts 106 . That is, when the pressing plate 105 is fixed to the mounting surface portion 104 by the bolt 106 , the proximal end portion 101 is sandwiched and fixed between the pressing plate 105 and the mounting surface portion 104 at the same time. By removing the bolt 106, the pressing plate 105 and the second seal 81 can be removed. Thus, the second seal 81 is detachably attached to the bracket 103 and thus to the side portion 100 of the rail 19 . The pressing plate 105 and the base end portion 101 are provided with bolt insertion holes, and the mounting surface portion 104 is provided with screw holes.

Also, in this embodiment, a third seal 107 is provided on the bottom surface of the rail 19 . The third seal 107 is formed of a sheet of constant thickness tc made of an elastic material such as rubber. As shown in FIG. 10(B), the third seal 107 seals the gap between the bottom surface of the rail 19 and the hatch cover 11, and the rail 19 is directly placed on the hatch cover 11 so that the hatch cover 11 does not move. to prevent damage (dents, scratches, etc.). The third seal 107 corresponds to a base seal member in the claims.

In the natural state shown in FIG. 10(A), the tip portion 102 of the second seal 81 extends to a position below the bottom surface portion of the rail 19 and the third seal 107 . The lower end of the tip portion 102 of the second seal 81 is located below the third seal 107 by a predetermined distance H.

The second seal 81 and the third seal 107 are provided over the entire length of the rail 19. The bracket 103 and the pressing plate 105 are preferably provided over the entire length of the rail 19 , but may be provided partially or intermittently over the entire length of the rail 19 . The bolts 106 are provided at predetermined intervals over the entire length of the rail 19 .

Now, as shown in FIG. 9, when rainwater exists on the hatch cover 11 on the left side (the side opposite to the hatch opening) of the first seal 80, the flow of the rainwater toward the right side (the side opposite to the hatch opening) is first It is blocked by the first seal 80 .

Even if rainwater flows through the first seal 80 , the rainwater flow is blocked by the second seal 81 and the third seal 107 .

By the way, if the second seal 81 deteriorates due to long-term use, etc., it needs to be replaced. During this replacement, the bolt 106 can be removed from the left side of the rail 19 to remove the existing second seal 81 . Also, a new second seal 81 can be attached by tightening the bolt 106 from the left side of the rail 19 .

Thus, since the second seal 81 can be replaced without laying the entire device on its side, the second seal 81 can be replaced much more easily than in the comparative example. In addition, since the replacement is easy, a cheaper second seal 81 can be adopted, and the manufacturing cost can be suppressed.

In addition, since the second seal 81 has a strong structure as described above, when the rail 19 or the third seal 107 are normally seated on the hatch cover 11 as shown in FIG. Even if there is a gap between the third seal 107 and the hatch cover 11 as shown in (C), the second seal 81 can be pressed against the hatch cover 11 with high surface pressure. Thereby, high sealing performance can be secured.

It should be noted that when the rail 19 through the third seal 107 are normally seated on the hatch cover 11, the surface pressure of the second seal 81 is higher than the surface pressure of the first seal 80.

Another feature of this embodiment is that the metal seal holder 151 is omitted because the lip seal 150 of the comparative example shown in FIG. 17 is omitted and the second seal 81 is used instead.

That is, since the seal holder 151 has a heavy structure, the use of the seal holder 151 increases the weight of the device. Further, since the

claws

155 and 156 must be machined on the legs 154 of the seal holder 151, the use of the seal holder 151 increases the manufacturing cost of the device.

However, in this embodiment, since the seal holder 151 is omitted, the disadvantages caused by adopting the seal holder 151 can be eliminated, the weight of the device can be reduced, and the manufacturing cost of the device can be suppressed.

Note that the third seal 107 may be omitted if possible. The proximal end portion 101 of the second seal 81 may be arranged in an orientation that is slightly inclined from the vertical orientation with respect to the hatch cover 11 . That is, the proximal end portion 101 of the second seal 81 may be arranged in a direction slightly inclined from the vertical.

Next, a modified example will be explained. The description of the same parts as those of the basic embodiment will be omitted, and the differences from the basic embodiment will be mainly described below.

[First modification]
As shown in FIG. 11 , the rain shelter for shipping according to the first modification further comprises a fourth seal 110 . The fourth seal 110 corresponds to an additional seal member recited in the claims.

The fourth seal 110 is made of an elastic material that is softer than the second seal 81, such as rubber. In particular, the fourth seal 110 is made of a porous elastic material such as foamed rubber.

The fourth seal 110 has a base end portion 111 that is detachably attached to the side portion 100 on the left side (opposite to the hatch opening side) of the rail 19 , and a tip end portion that extends downward from the base end portion 111 and contacts the hatch cover 11 . 112. A line a indicates the boundary position between the proximal end portion 101 and the distal end portion 102 of the second seal 81 and the boundary position between the proximal end portion 111 and the distal end portion 112 of the fourth seal 110 . The thickness of the fourth seal 110 is a relatively large constant thickness td. The thickness td of the fourth seal 110 is made larger than the thickness tb of the base end portion 101 of the second seal 81 .

The fourth seal 110 has a vertically elongated rectangular cross-sectional shape in its natural state as shown in FIG. That is, the fourth seal 110 is arranged vertically. Thereby, the tip portion 112 can be efficiently pressed against the hatch cover 11 .

The fourth seal 110 is attached to the side portion 100 of the rail 19 via a common bracket 113 together with the second seal 81 . The bracket 113 is fixed at a predetermined height position on the side portion 100 and horizontally extends leftward from the side portion 100 . The bracket 113 corresponds to a bracket and an additional bracket in claims. A left mounting surface portion 114A and a right mounting surface portion 114B protruding downward are provided at an intermediate portion of the bracket 113 with a space therebetween.

The base end portion 101 of the second seal 81 is superimposed on the left surface of the left mounting surface portion 114A. Also, the proximal end portion 111 of the fourth seal 110 is sandwiched between the left mounting surface portion 114A and the right mounting surface portion 114B. A pressing plate 115 is superimposed on the left surface of the base end portion 101 of the second seal 81 . The pressing plate 115 , the base end portion 101 of the second seal 81 , and the base end portion 111 of the fourth seal 110 are aligned and fixed to the bracket 113 by bolts 116 . That is, after the bolt 116 is sequentially inserted through each bolt insertion hole of the pressing plate 115, the base end portion 101 of the second seal 81, the left mounting surface portion 114A, and the base end portion 111 of the fourth seal 110, the right mounting surface portion 114B is tightened into the screw hole of As a result, the pressing plate 115 , the base end portion 101 of the second seal 81 , and the base end portion 111 of the fourth seal 110 are fixed to the bracket 113 .

By removing the bolt 116, the pressing plate 115, the second seal 81 and the fourth seal 110 can be removed. In this way, not only the second seal 81 but also the fourth seal 110 are detachably attached to the bracket 113 and thus to the side surface portion 100 of the rail 19 .

In the natural state shown in FIG. 11(A), the tip 112 of the fourth seal 110 extends below the bottom surface of the rail 19 and the third seal 107 . The lower end of the tip portion 112 of the fourth seal 110 is located below the third seal 107 by a predetermined distance Ha. In the illustrated example, the lower end of the tip portion 112 of the fourth seal 110 is located slightly below the lower end of the tip portion 102 of the second seal 81 . That is, H<Ha. When the rail 19 is placed on the hatch cover 11, the fourth seal 110 produces an appropriate surface pressure due to the reaction force received from the hatch cover 11, and exhibits an excellent waterproof function.

A fourth seal 110 is also provided over the entire length of the rail 19 . The bracket 113 and the pressing plate 115 are preferably provided over the entire length of the rail 19 , but may be provided intermittently over the entire length of the rail 19 . The bolts 116 are provided at predetermined intervals over the entire length of the rail 19 .

As shown in FIG. 11(B), when the rail 19 is placed on the hatch cover 11 , not only the second seal 81 but also the fourth seal 110 are pressed against the hatch cover 11 . Therefore, the fourth seal 110 can also dam the flow of rainwater toward the rear side (hatch opening side), and the sealing performance can be improved.

At this time, the tip portion 112 of the fourth seal 110 is compressed in a direction perpendicular to the thickness td direction and expanded in the thickness td direction. As shown in FIG. 11(C), when a gap is created between the third seal 107 and the hatch cover 11, the amount of compression and expansion of the fourth seal 110 is reduced, but the seal is still constant. performance can be ensured.

When replacing the fourth seal 110, similarly to the case of the second seal 81, the existing fourth seal 110 is removed by removing the bolt 116 from the left side of the rail 19, and the bolt 116 is tightened from the left side of the rail 19. Then, a new fourth seal 110 can be installed. Therefore, the fourth seal 110 can be replaced without laying the entire device on its side, and the replacement can be easily performed.

In addition, since the fourth seal 110 is softer than the second seal 81, it follows the irregularities of the hatch cover 11 better than the second seal 81. In particular, since the fourth seal 110 is made of a porous elastic material, such as foamed rubber, it is possible to achieve extremely good conformability to irregularities.

FIG. 12 shows a case where the upper surface of the hatch cover 11 has a stepped projection 117 formed by a weld bead. Since the hatch cover 11 is generally manufactured by welding steel plates, such protrusions 117 are often present. In the illustrated example, the protrusion 117 extends in the left-right direction, that is, in the direction from the side opposite to the hatch opening toward the hatch opening. Then, the second seal 81, the third seal 107 and the fourth seal 110 are pressed against the projection 117 from above. The longitudinal direction of these seals intersects, in particular perpendicularly, the longitudinal direction of the projections 117 .

In this case, as shown in FIG. 12(B), the second seal 81 cannot completely follow the outer shape of the projection 117, and on both sides of the projection 117, between the second seal 81 and the hatch cover 11 and the projection 117 A gap 118 is formed in the

However, as shown in FIG. 12(C), in the case of the fourth seal 110, the fourth seal 110 can completely follow the outer shape of the projection 117. Therefore, the formation of gaps on both sides of the projection 117 can be avoided, and the sealing performance can be improved.

In particular, since the fourth seal 110 can be compressed and deformed by crushing the internal air bubbles, the followability to the outer shape of the other party is extremely good. Therefore, both sides of the protrusion 117 can be deformed to follow the angular shape transitioning from the surface of the protrusion 117 to the upper surface of the hatch cover 11, and the formation of a gap can be avoided.

Therefore, rainwater passing through the gap 118 between the second seal 81 and the hatch cover 11 can be reliably blocked by the fourth seal 110 . It should be noted that the third seal 107 can also be made of the same material as the fourth seal 110 .

FIG. 18 shows a case where the upper surface of the hatch cover 11 has a step 117A. Since the hatch cover 11 is generally manufactured by joining steel plates together by welding, such a step 117A may exist at the joint. In the illustrated example, the step 117A extends in the left-right direction, that is, in the direction from the side opposite to the hatch opening toward the hatch opening. The longitudinal directions of the second seal 81, the third seal 107 and the fourth seal 110 intersect, particularly perpendicular to, the longitudinal direction of the step 117A.

Also in this case, as shown in FIG. 18(B), the second seal 81 cannot completely follow the outer shape of the step 117A, and a gap 118 is formed above the step 117A.

However, as shown in FIG. 18(C), in the case of the fourth seal 110, the fourth seal 110 can completely follow the outer shape of the step 117A. Therefore, it is possible to avoid the formation of a gap above the step 117A, and to improve the sealing performance.

[Second modification]
As shown in FIG. 13, in the second modification, the arrangement of the second seal 81 and the fourth seal 110 is reversed from that in the first modification, with the second seal 81 on the right side (hatch mouth side) and the A 4-seal 110 is located on the left side (opposite to the hatch opening).

Also, the configuration around the bracket is slightly changed from the first modified example.

The second seal 81 and the fourth seal 110 are detachably attached to the side portion 100 of the rail 19 via a common bracket 123. The bracket 123 is fixed at a predetermined height position on the side portion 100 and horizontally extends leftward from the side portion 100 . A left mounting surface portion 124A and a right mounting surface portion 124B projecting downward are provided in an intermediate portion of the bracket 123 . However, these intervals are larger than the interval between the left mounting surface portion 114A and the right mounting surface portion 114B of the first modified example.

The base end portion 111 of the fourth seal 110 is superimposed on the left surface of the left mounting surface portion 124A. The front pressure plate 125A is superimposed on the left surface of the base end portion 111 of the fourth seal 110 . The left bolt 116A aligns the left pressing plate 125A and the base end portion 111 of the fourth seal 110 with the left mounting surface portion 124A and stops them.

The base end portion 101 of the second seal 81 is superimposed on the left surface of the right mounting surface portion 124B. The right pressure plate 125B is superimposed on the left surface of the base end portion 101 of the second seal 81 . The right bolt 116B aligns the right pressure plate 125B and the second seal 81 with the right attachment surface portion 124B and stops them.

According to this modification, since the fourth seal 110 and the second seal 81 are attached by

separate bolts

125A and 125B, it is not necessary to remove the other seal when replacing one seal, and the replacement work can be performed smoothly. It can be carried out.

[Third Modification]
As shown in FIG. 14, in the third modified example, the second seal 81 and the fourth seal 110 are attached to different side portions of the rail 19 . That is, the second seal 81 is attached to the left side surface portion 100 of the rail 19 as in the basic embodiment (FIG. 10). However, the fourth seal 110 is attached to the right side portion 130 of the rail 19 .

The mounting method of the second seal 81 is the same as in the basic embodiment (Fig. 10). On the other hand, the mounting method of the fourth seal 110 is the same as the mounting method of the second seal 81 except that it is bilaterally symmetric with respect to the rail 19 . Therefore, each corresponding member is shown and detailed description is abbreviate|omitted.

The right bracket 133 corresponds to the left bracket 103 , the right pressure plate 135 corresponds to the left pressure plate 105 , and the right bolt 136 corresponds to the left bolt 106 .

According to this configuration, even if rainwater flows toward the right side (hatch mouth side) and passes through the third seal 107, the fourth seal 110 can dam the rainwater flow.

Also, when replacing the fourth seal 110, the existing fourth seal 110 can be removed by removing the bolt 136 from the right side of the rail 19, and a new fourth seal 110 is attached by tightening the bolt 136 from the right side of the rail 19. be able to. Therefore, the fourth seal 110 can be replaced without laying the entire device on its side, and the replacement can be easily performed.

[Fourth Modification]
As shown in FIG. 15, the fourth modification is substantially the same as the basic embodiment (FIG. 10), but the direction of curvature of the distal end portion 102 of the second seal 81 is opposite to that of the basic embodiment. That is, as shown in FIG. 15A, the tip portion 102 of the second seal 81 is curved so that the tip side faces rightward (toward the hatch opening) in the natural state.

Correspondingly, the proximal end 101 of the second seal 81 is positioned further to the left than in the basic embodiment, even when the distal end 102 is bent as shown in FIG. 15(B). Tip portion 102 does not interfere with rail 19 and third seal 107 . Moreover, the length of the bracket 103 is also made longer toward the left side, and the position of the mounting surface portion 104 is also made further to the left side.

Even if the bending direction of the distal end portion 102 is changed in this manner, the same effects as those of the basic embodiment can be exhibited.

It should be noted that it is possible to additionally provide the fourth seal 110 in this modified example as well.

[Fifth Modification]
As shown in FIG. 16, in the fifth modification, the second seal 81 is detachably attached directly to the left side portion 100 of the rail 19 without a bracket.

The base end portion 101 of the second seal 81 is oriented perpendicular to the hatch cover 11, that is, arranged vertically, and overlaps the left side surface portion 100 of the rail 19. As shown in FIG. As shown in FIG. 16A, the tip portion 102 of the second seal 81 is curved so that the tip side faces left (opposite to the hatch opening) in the natural state.

A pressing plate 105 is superimposed on the left surface of the base end portion 101 . The pressing plate 105 and the base end portion 101 are aligned and fixed to the side portion 100 by bolts 106 .

According to this configuration, the intermediate bracket can be omitted, so the device can be made simpler, lighter, and cheaper.

Although the embodiments of the present disclosure have been described in detail above, various other embodiments and modifications of the present disclosure are conceivable.

For example, the device main body may be of a fixed type that does not expand and contract. In this case, the device main body may be made of a relatively lightweight material such as resin (including FRP), aluminum, or the like.

The second seal 81 and the fourth seal 110 may be split in the longitudinal direction of the rail 19. By doing this, when the size of the gap between the rail 19 and the hatch cover 11 changes according to the position of the rail 19 in the longitudinal direction, the optimum length (from the base end to the tip end) according to the size of the gap at each position can be determined. ) can be employed at each position to improve sealing performance.
