Description

[Detailed Description of the Invention] This invention relates to a watertight mechanism for an inboard rampway device that connects an upper deck and a lower deck in a vehicle transport vessel or the like by a ramp.

Conventionally, as this type of inboard rampway device, one shown in FIG. 1 is known.

In other words, there are multiple decks A, B,
C and D are provided.

Each of the decks A, B, C, and D has an opening 1 located within the same plane section, and each deck A,
Ramp 2 that can be ascended and descended freely connecting B, C, and D with a ramp
... will be established.

In other words, one end of the lamp 2 is connected to the end of the opening 1 of each deck A to D via the end hinge 3, and the other end is connected to the tip of a wire 4 that is expanded and contracted by a jigger cylinder or the like (not shown). has been done.

Therefore, each lamp 2... rotates around the end hinge 3 due to the expansion and contraction of the wire 4, and its free tip is held at a predetermined position, so that each lamp 2... ) or a ramp connecting the upper and lower decks is formed.

In addition, as shown in the figure, when loading a high-height vehicle onto deck D, for example, when the vehicle passes through ramp 2 connecting decks B and C, opening 1 on deck B
There is a risk of back striking at the end, which could damage the vehicle.

In order to prevent this, a lamp cover 5 that can be raised and lowered freely corresponding to the lamp 2 is also provided in the opening 1 of the deck B.
is provided, and the free tip of the ramp 2 is lifted upward via a wire (not shown), etc., like the ramp 2, to prevent the vehicle from back hitting as described above. It's becoming like that.

After loading the vehicle, turn on ramp 2.
While lifting the lamp cover 5 upward, the lamp cover 5 is lowered to make both 2 and 5 horizontal and stored in the opening 1, and these are used as the deck B.

When the lamp 2 and the lamp cover 5 are stored and formed on the deck B as shown in the figure, it may be necessary to keep the deck B watertight during storage.

As this watertight mechanism, for example, a gasket is provided at the side end portions of the lamp 2 and the lamp cover 5, which engages with a tightening bar provided on the side edge of the opening 1 from below on the lamp 2 side and from above on the lamp cover 5 side. In addition, it is conceivable to provide a tightening bar on the lamp 2 side of each free tip, and provide a gasket that engages with the tightening bar on the lamp cover side.

However, with such a watertight mechanism, there is a problem in that although watertightness can be ensured at the side portions, watertightness cannot be ensured at the corner portions of the meeting portion of the lamp 2 and the lamp cover 5.

In other words, due to the structure of the rampway device described above, the gaskets attached to the side ends of the lamp 2 and lamp cover 5 are arranged so that they engage with the tightening bars provided on the side edges of the opening 1 from different directions, above and below (of course, the tightening bars also protrude in different directions on the lamp 2 side and the lamp cover 5 side), so that a space is inevitably formed at the corner portion due to the step between the gaskets of the lamp 2 and the lamp cover 5, and it is impossible to completely close this space between the tightening bars provided at the free ends of each and the gaskets.

Therefore, the object of this invention is to provide a watertight mechanism that can ensure watertightness even in the above-mentioned corner portions.

To this end, in this idea, in the above-mentioned watertight mechanism, the gasket provided on the lamp is bent and extended at right angles at the corner, and is tilted upward so that it connects flush with the tightening bar provided at the tip. On the other hand, a roughly triangular corner gasket that closes the space between this inclined portion and the gasket on the lamp cover side is placed on the side edge of the opening in the deck at the connection point of the tightening bar whose protruding directions are different from each other. and is configured to provide.

An embodiment of this invention will be described below based on the drawings.

In Fig. 2, 10 is a deck corresponding to deck B in Fig. 1, and 11 is an opening 1 of the deck 10.
A lamp 0A is provided to be freely raised and lowered, and 12 is a lamp cover that is also provided to be freely raised and lowered to the opening 10A.

As for these watertight mechanisms, first, as shown in FIG. 3, the side end 11A of the lamp 11 is engaged from below with a downward tightening bar 13 installed on the side edge of the opening 10A of the deck 10. A band-shaped packing 14 is provided. In addition, 15 in Figure 3
Reference numeral A denotes a wedge that can move forward and backward, tightening the gasket 14 when the lamp is stored, and also fixing and holding the lamp 11 on the deck 10.
A plurality of are provided at the side end portion 11A of the lamp 11 at predetermined intervals.

On the other hand, the side end 12 of the lamp cover 12
As shown in FIG. 4, A now has an opening 10A.
A packing 17 is provided on the side edge to engage from above with a tightening bar 16 laid upward. Similar to the lamp 11, this lamp cover 12 also has a wedge 15B as described above at the side end 12A.
There are multiple locations along the route.

The opposing free tips 11B and 12B of these lamps 11 and lamp covers 12 have
As shown in FIG. 5, there is an upward tightening bar 18 on the lamp 11 side, and a lamp cover 12.
A gasket 17 is provided on the side to engage the tightening bar 18 from above. Therefore,
This gasket 17 on the lamp cover 12 side is provided integrally with the gasket 17 provided on the side end portion 12A. Incidentally, a wedge 15C is also provided between these, which is located on the lamp 11 side and moves forward and backward with respect to the lamp cover 12.

Next, in order to make the corner part of the meeting part of the lamp 11 and the lamp cover 12 watertight, as shown in FIGS.
is bent and extended at a right angle along the tip portion 11B at the corner portion, while the tip portion 1 is formed short in advance.
It is tilted upward so as to be connected substantially flush with the tightening bar 18 of 1B. 14A in the figure is the inclined portion.

As is clear from FIG. 9, a corner gasket 20 for closing a space 19 having a triangular cross section formed between the inclined portion 14A of the gasket 14 and the gasket 17 of the lamp cover 12 is attached to the deck 10. It is provided at the side edge of the opening 10A.

The corner packing 20 has a protruding end formed in a triangular shape with a size corresponding to the volume of the space 19, and a columnar base end that is pre-aligned with the opening 1.
After being housed in a concave corner box 21 provided on the 0A side edge at the connection portion of the tightening bars 13 and 16 whose protruding directions are different from each other, it is fixed with an adhesive or the like.

This corner box 21 includes convex bars 22A and 22B that are integrated with the corner box 21 as appropriate.
and is watertightly connected to the connection ends of the tightening bars 13 and 16 via connection plates 23A and 23B.

Because of this structure, from the time of forming the slope as shown in FIG.
1, 12 are retracted, the side ends 11A, 12A and free tips 11B, 12B of the lamp 11 and lamp cover 12 are connected to the tightening bars 13, 16 and 18 and the packings 14, 17.
As described above, the opening 10A of the deck 10 is held watertight by the engagement of the opening 10A of the deck 10.

On the other hand, at the corner portions of the lamp 11 and the lamp cover 12, the space 19 that is inevitably formed due to the structure of this rampway device is automatically closed by the corner packing 20 when stored. Upper surface part 20A of corner packing 20
There is a gasket 17 on the lamp cover 12 side, and a gasket 14 on the lamp 11 side is on the lower surface part 20B.
and 14A (slanted portion) are respectively crimped, so that the space 19 is kept watertight between the gaskets.

As a result, the lamp 11 and the lamp cover 12 are kept completely watertight from the opening 10A of the deck 10 over the entire circumference.

In addition, since the watertight mechanism described above does not use any movable parts, the structure can be simplified, and
There is an advantage that watertightness is automatically ensured when the lamp 11 and lamp cover 12 are closed.

As explained above, according to this invention, the space formed between the gasket of the lamp and the lamp cover at the corner portion is closed by a corner gasket of a predetermined shape provided on the deck side, and these gaskets are made watertight with each other. Since it is constructed so that it can be attached to the deck opening, it is possible to obtain the effect that the lamp and the lamp cover are completely watertight from the deck opening all around with a simple structure.
