Description

[Detailed description of the invention] This invention is a double-opening foldable hatch cover that can be opened and closed on the hatch combing.
This invention relates to an improvement in the seal between opposing front panels.

A general type of double-folding hatch cover has a plurality of panels foldably connected in the longitudinal direction of the hatch, as shown in FIG. 1, two panels being symmetrically connected to each other in the figure. 01 and 02 are 01' and 0 on the left pivot panel and front panel in the figure.
2' designates a right-hand pivot panel and a front panel, each pivot panel and the front panel being hingedly connected.

In this type of hatch cover, conventionally the front panels 02, 02' facing toward which the hatch is closed are
As shown in FIG. 2, a wedge 03 is bridged between the adjacent edges of the upper panels of the same unit, and by driving the wedge 03, the outer surface of the front end plate 04' of the front panel 02' on the right side in the figure is lowered. Gasket 06 built into gasket retainer 05 welded to
is strongly pressed by a seal bar 08 that projects vertically from the front end of the bottom plate 07 of the other front panel 02 to ensure a seal between the front panels 02 and 02'.

In this conventional type of hatch cover, when opening the hatch cover that closes the hatch,
First, the bridged wedge 03 is pulled out, and then the roller 010 attached to the tip of the front panel 02' is pushed up using the jack 09 to engage the seal bar 08 and gasket 06 as shown in FIG. need to be dissociated. However, recently it is customary to mount wood and containers on the panels.

For example, pivot panel 01', front panel 0
If there is a load on 2', the other pivot panel 0
1. Even if an attempt is made to open the front panel 02, the front panel 02 cannot be opened because it is blocked by the engagement between the gasket 06 and the seal bar 08. Further, when the hatch cover is extended and the wedge 03 is driven in, if there is a load on the front panel 02, the panel flexes and an unreasonable force is applied to the wedge 03. Therefore, in order to pull out the wedge 03, it is necessary to hit it strongly with a hammer, and there is a risk that the wedge mounting portion may be damaged. In addition, since the wedge 03 protrudes from the panel, the portion of the wedge to be bridged must be machined into a concave shape, which is troublesome in terms of machining and requires additional man-hours.

Furthermore, if there is a difference in the amount of deflection between the front panels 02 and 02', it will be difficult to drive in the wedges 03, which will require a lot of work, and if the wedges are not driven in sufficiently, problems will arise in terms of maintaining watertightness.

The present invention was made in order to eliminate such conventional drawbacks.The outer surface of the front end plate of one of the opposing front panels has its left and right ends close to the left and right side plates. A horizontally extending protruding flexible gasket is attached, and the front end plate of the other front panel is provided with a watertight abutment member having a flat front surface that comes into pressure contact with the flexible gasket when the hatch cover is extended on its outer surface. In addition, rising gaskets are provided at the left and right ends of the flexible gasket and extend upwardly along the inner surfaces of the left and right side plates of the front panel, respectively, and whose upper portions are bent inward in a hook shape. A solid gasket for connecting the bent end of the side rising gasket and the left and right ends of the flexible gasket is interposed, and the other side gasket is connected to the rising gasket and the solid gasket connected thereto. It is a double-opening foldable hatch cover which is provided with a seal bar whose upper part is bent inward along the watertight contact member on the front panel side, and when the hatch cover is extended, the seal portion between the facing front panels is of a butting type. Therefore, even if there is a cargo on one panel of the opposing hatch covers, the other hatch cover can be opened and closed.

The present invention will be described with reference to an embodiment shown in FIG. 4 and the subsequent drawings.

FIG. 4 is a plan view showing the hatch cover according to the present invention in an expanded state, and the pivot panel 1a, the front panel 2a, the front panel 2f, and the pivot panel 1a, front panel 2a, front panel 2f, Part panel 1f
is located. Pivot panels 1a and 1f at both ends are rotatably pivoted around main hinges 4a and 4f. The front panel 2a is connected to the pivot panel 1a by an intermediate hinge 5a, and the other front panel 2f is connected to the pivot panel 1f by an intermediate hinge 5f, and the connected panels on both sides are The rail on the hatch coaming is moved by the roller 6 by pulling the opening/closing cables 10a and 10f shown in FIG.
a and 6f are rolled and folded onto the end ramps 7a and 7f, respectively, and when the cables are loosened, the rollers are lowered on the end ramps and the hatch cover is expanded. In the view of FIG. 5, the right side connection panel is shown in a folded and stored state by a solid line. Figure 6 is an enlarged cross-sectional view taken along the - line in Figure 4, showing the sealing condition between the panels, and Figure 7 shows the state of the seal between the panels, with cargo on one panel and the other panel bending in Figure 6. The sealing state between panels when a difference δ occurs is shown.

Conventionally, maintaining watertightness between opposing front panels was the second step.
As shown in the figure, the seal bar 08 facing upward was fitted into the gasket 06 facing downward, but in this proposal, one front panel 2
A flexible gasket 8 having a nipple-shaped cross section is positioned downwardly on the outer surface of the front end plate 14a of FIG. The front end plate 1 of the other front panel 2f corresponds to
A watertight contact member 11 whose front surface is flat and which presses the gasket 8 when the hatch cover is expanded is welded to the outer surface of the hatch cover 4f. The gasket 8 is made by covering the surface of a spongy rubber 8' with neoprene 8'', and the bottom surface is fixed to the outer surface of the front end surface 14a with adhesive.The base of the gasket 8 is attached to the retaining plate 16 from above and below. and 16'.The watertight member 11 has L.
Shaped steel is used, and a rust-free material such as a stainless steel plate 12 is attached to the front surface to prevent damage to the surface of the gasket 8 and ensure sealing with a smooth surface.

Next, the left and right side plates 1 of the front panel 2a
Regarding watertight maintenance on the 7a and 17f sides, Figures 8 to 1
This will be explained with reference to FIG.

The watertight devices on the left and right side plates 17a and 17f are symmetrical and have the same structure, with rising gaskets located at the left and right ends of the flexible gasket 8 via connecting solid gaskets. Become.

FIG. 9 shows the arrangement of the flexible gasket 8, the connecting solid gasket 9, and the rising gasket 19b. The rising gasket 19b is a downwardly directed gasket holder 18 provided horizontally along the inner surface of the lower part of the side plate 17a of the front panel 2a.
It extends upward along the inner surface of the side plate 17a from the tip of the gasket 19a housed in the gasket 19a, the upper part of which is bent inward at right angles, and the bent tip is between the tip of the flexible gasket 8 and the end of the flexible gasket 8. facing each other with a slight distance between them. The above rising gasket 19b
Since the shapes of the gasket 8 and the flexible gasket 8 are different, a solid gasket 9 for connection is interposed between the two gaskets as shown in FIGS. 9 and 10 in order to make the connection between them smooth. In FIGS. 8 and 9, 20a is a seal bar vertically welded onto the port rim material 21. In FIGS. Note that the watertight device on the opposite side plate side of the side plate 17a is the same as that on the side plate 17a side, so a description thereof will be omitted.

Front panel 2f facing each other to maintain watertightness of the rising gasket and connection gasket in the above
As shown in FIGS. 11 and 12, the seal bar 13 with its upper part bent inward at right angles is attached to the watertight contact member 11.
Install it almost flush with the surface of the That is, the seal bar 13 is vertically welded to the upper surface of the gasket holder 18f, and the bent portion is disposed along the watertight contact member 11. In addition, in FIG. 11, 19f is a gasket, and 20f is a seal bar.

In this way, in the present invention, the opposing front panel 2
One front end plate 14a (or 14f) of a, 2f
A protruding flexible gasket 8 is provided horizontally on the outer surface of the gasket, and a watertight contact member 11 having a flat front surface is attached to the corresponding outer surface of the other front end plate 14f (or 14a). Therefore, when the hatch cover folded approximately vertically is expanded, the flexible gasket 8 and the watertight contact member 11 abut each other head-on, and the flexible gasket 8 is compressed. If cargo a (see Figure 5) is placed on the panel on the front panel 2a side, the difference in deflection between front panels 2a and 2f will be δ (see Figure 7) due to the load. However, the flexible gasket 8 deforms under pressure and the seal between the panels is maintained. Front panel 2a, 2
If there is no cargo on the surface f, the amount of deflection of both panels is the same, and as shown in FIG. 6, the upper surfaces of both panels are flush and the flexible gasket 8 is in the normal state.

Further, since the seal between the front panels 2a and 2f is of a butt seal type, even if cargo is placed on one panel, the other panel can be opened and closed.

Further, connecting solid gaskets 9 are interposed between the left and right end portions of the flexible gasket 8 and rising gaskets 19b having different shapes, forming a series of gaskets. A seal bar 13 is flush with the watertight member 11 on the front panel side.
, the seal on the side plate side also abuts, thus making it possible to open and close the panel regardless of the presence or absence of cargo on the panel. Furthermore,
Maintaining watertightness between the front panels does not require the conventional cross-linking method by driving wedges; therefore, the upper surface of the upper member of the front panel can be made into a flat area instead of the conventional wedge-bridged portion having a concave shape. This reduces processing costs and makes it easy and safe to load and unload cargo onto the panel.
