DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal member of a floor transfer device mounted on a vehicle such as a large truck or a trailer, and more particularly to a seal member between a plurality of parallel floor members constituting a floor. The present invention relates to a seal member having an enhanced water intrusion prevention function.

[0002]

2. Description of the Related Art A floor conveyor having a floor conveyor structure is provided with a plurality of parallel floor members extending in a substantially horizontal front-rear direction, as in Japanese Utility Model Publication No. 3-57553. Each floor member is capable of reciprocating at a constant stroke in the front-rear direction, and by intermittently feeding a load such as a granular material loaded on the floor member in the front-rear direction by controlling the direction and order of the front-back movement of each floor member. It has become. In addition, a seal member is disposed between the plurality of floor members in parallel to prevent a load such as powdery particles from dropping.

[0003]

By the way, in a floor surface transport device mounted on a large truck or a trailer,
Since the lower surface is directly exposed to the road, when the tire of the vehicle jumps up the water vigorously in rainy weather etc., the splashing water enters a slight gap between the floor member and the seal member. There was a possibility. Conventional seal members, such as Japanese Utility Model Publication No. 3-57553, generally have only one downward lip portion, which is insufficient to completely prevent infiltration of splashing water. In particular, when the particulate matter accumulates between the upward lip portion and the downward lip portion, there is a problem that the possibility that the water jumps up to the floor surface by capillary action using the particulate material increases. .

The present invention has been made to solve such a problem, and an object of the present invention is to provide a seal member in which water splashing from below a floor surface transport device is less likely to enter the floor surface. It is in.

[0005]

In order to solve the above-mentioned problems, a seal member of a floor surface conveying device according to the present invention is provided with a plurality of seal members extending in a substantially horizontal front-rear direction and capable of reciprocating at a constant stroke in the front-rear direction. By arranging the floor members in parallel on the same plane to form a floor surface on the upper surface of each floor member, the load placed on the floor surface is controlled by controlling the direction and order of forward and backward movement of each floor member. In a floor transfer device that intermittently feeds on a floor, a seal member that seals a gap between the floor members,
A base portion fitted and fixed along a side surface longitudinal direction of one of the floor members, at least one first upward lip portion extending obliquely upward from the base portion toward a side surface of the other floor member, At least two downward lip portions extending obliquely downward from the base toward the side surface of the other floor member.

As described above, the downward lip portion is formed by at least two
With this arrangement, it is possible to reliably prevent the splashing water from entering even if the splashed water hits the sealing member, and the space between the two downward lip portions is not larger than the floor surface. The structure is at least doubly isolated between the upward lip portion and one downward lip portion, so that it is more difficult for the cargo or the like to penetrate the cargo than before, and the floor surface due to the capillary phenomenon It is possible to more reliably prevent the intrusion of water into the upper part.

Although the seal member according to the present invention has at least one upward lip portion as a sufficient countermeasure against water intrusion, the sealing member between the base portion of the seal member and the upward lip portion has a small size. In order to prevent clogging, it is desirable to provide a second upward lip extending upward toward the floor member side opposite to the one upward lip.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an enlarged cross-sectional view of only two floor members 10 and 11 constituting the floor surface transfer device.
A large number of such floor members 10 and 11 are arranged side by side to constitute a floor surface transfer device. The two floor members 10 and 11 are slidable in the front-rear direction with respect to each other, and a gap H is provided between the two. The seal member of the present invention is disposed between the floor members 10 and 11 along the longitudinal direction so as to close the gap H.

As shown in detail in FIG. 2, the sealing member 1 has a substantially spherical or Y-shaped base portion 2 fitted in a fitting groove 5 having a circular cross section formed on one side surface of one of the floor members 10. Have been combined. The sealing member 1 has a first upward lip portion 3b extending obliquely upward from the base portion 2 toward one side surface of the other floor member 11, and one floor member 10 having a fitting groove 5 therein.
Second upward lip portion 3 extending upward toward one side surface
a. Further, the seal member 1 has downward lip portions 4a and 4b extending obliquely downward from the base 2 toward one side surface of the other floor member 11 so as to be substantially parallel to each other. Second upward lip portion 3a and downward lip portions 4a, 4
b extends in the natural state before being attached to the floor member 10 as shown by a two-dot chain line in the figure, but when disposed between the floor members 10 and 11, the lateral width direction is slightly narrowed, and Member 1
It is configured to be lightly pressure-bonded to the side surfaces 0 and 11.

The seal member 1 is constructed as described above. When a tire on which a truck on which a floor surface transfer device is mounted passes through a puddle or the like in rainy weather jumps up the water, the water is applied to the floor members 10 and 11. The sealing member 1 penetrates through the gap H between
On the lower surface of However, since the first and second downward lip portions 4a and 4b doubly close the gap H, the situation where the splash water reaches the upward lip portion 3b beyond the downward lip portions 4a and 4b is substantially. There will be none. Also,
Even if water jumps over the downward lip portion 4a and enters the space between the downward lip portions 4a and 4b,
Conventionally, water was allowed to penetrate to the floor surface by capillarity using the particulate matter accumulated therein as a medium. However, in the seal member 1 of the present invention, the space between the downward lip portions 4a and 4b is limited to the floor surface. Is separated doubly by the two lip portions of the upward lip portion 3b and the downward lip portion 4b, so that the cargo particles do not accumulate in this space, and therefore, the water is splashed up by the capillary phenomenon. Partial intrusion to the floor can be prevented.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible. For example, the downward lip portions 4a and 4b of the seal member 1 are In addition to the upper and lower stages as in the embodiment, it is also possible to employ three or more stages while appropriately considering the friction coefficient between the floor members 10 and 11. Further, the downward lip portion 4a may be constituted by a pair of left and right sides opened in an inverted Y-shape, whereby the function of preventing water from entering the fitting groove 5 can be enhanced.

[0012]

As described above, the present invention extends downwardly in addition to at least one upward lip extending diagonally upward from the base of the seal member toward one side of the opposite floor member. Since at least two downward lip portions are provided, it is possible not only to prevent spillage of powdery material or the like as a load from a gap between the adjacent floor members, but also to splash to the lower surface of the floor member in rainy weather or the like. Even if the water rises vigorously, the double structure of the downward lip prevents water from entering, and even if some water enters the space between the downward lips, this space will remain on the floor. Since the surface is doubly isolated by at least two lip portions of the upward lip portion and the downward lip portion, there is no possibility that the particles of the cargo enter the space, and the particles are used as a medium. Capillaries Elephant by water intrusion can be prevented effectively.
