BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a watertight structure of a truck lift and a substantially L-shaped weather strip constituting the watertight structure according to the present invention.

[0017] The watertight structure 1 of the present invention,
As illustrated in FIGS. 1 and 2, in a truck lift including a bottom rail 2 and corner posts 6 attached to both left and right ends 5 of the bottom rail 2, water flowing from a peripheral portion of the track lift to the inside of the cargo bed. This is to prevent intrusion of dust and dust.

The watertight structure 1 of the truck lift of the present invention comprises:
A bottom weather strip 4 attached to the lower side 3 of the bottom rail 2, a post weather strip 7 attached to the corner post 6, and a substantially provided at a corner 8 between the bottom weather strip 4 and the post weather strip 7. An L-shaped weather strip 11, and the substantially L-shaped weather strip 11
A horizontal arm 12 positioned on an extension of the bottom weather strip 4 and connected to the bottom weather strip 4, and a vertical arm 13 positioned on an extension of the post weather strip 7 and connected to the post weather strip 7. Have.

A feature of the present invention is that at least one of the horizontal arm 12 and the vertical arm 13 of the substantially L-shaped weather strip 11 and the bottom weather strip 4 form an overlapping structure region W. Is to do.

(Substantially L-shaped Weather Strip) First, the substantially L-shaped weather strip will be described.

The substantially L-shaped weather strip 11 is shown in FIG.
As shown in FIG. 3, it is provided at a corner portion 8 composed of a lower side portion 3 of the bottom rail 2 and corner posts 6 mounted on both left and right ends 5 of the bottom rail 2, and extends in the horizontal direction. It has a horizontal arm 12 and a vertical arm 13 extending in the vertical direction.

This substantially L-shaped weather strip 11
It is formed of a material having appropriate elasticity. The substantially L-shaped weather strip 11 having an appropriate elasticity allows the floor frame 2 to be closed when the truck tilt is closed via the hinge 61.
3 can be flexibly deformed by being pressed against the upper surface 28 or the side surface 29. Similarly, when pressed against the column flange 62, the column flange 62 can be flexibly deformed. As a result, the gap between the upper surface 28 or the side surface 29 of the floor frame 23 and the gap between the floor frame 23 and the column flange 62 can be eliminated. Further, since the bottom weather strip 4 and the post weather strip 7 are also flexibly deformed, a gap generated between the bottom weather strip 4 and the post weather strip 7 can be eliminated. Further, since the substantially L-shaped weather strip 11 having appropriate elasticity is easily deformed, there is an advantage that the substantially L-shaped weather strip 11 can be easily mounted on the corner portion 8. In addition, the substantially L-shaped weather strip 1
As a material constituting 1, various materials such as sponge rubber and solid rubber can be used as long as they have been conventionally used as materials for various weather strips, and are not particularly limited.

The horizontal arm 12 extends in the horizontal direction and is connected to the bottom weather strip 4. Such a horizontal arm 12 is located on an extension of the bottom weather strip 4. Then, the contact surface 14 of the horizontal arm 12 and the bottom weather strip 4 having a long shape are formed.
Is provided in such a manner that the contact surface 26 abuts against the contact surface 26.

In the substantially L-shaped weather strip 11, the horizontal arm 12 and the bottom weather strip 4
Preferably form an overlapping structure region W.

The overlapping structure region W is formed in a region where the horizontal arm 12 and the bottom weather strip 4 are in contact with each other. For example, the overlapping structure region W is in contact with the horizontal arm 12 shown in FIGS. Even if the overlapping area is formed by the surface 14 and the contact surface (not shown) of the bottom weather strip 4 having a shape corresponding to the contact surface 14, for example, FIG. (H), an overlapping area constituted by the covering piece 16 of the horizontal arm 12 and the outer peripheral surface 43 (see FIG. 2) of the bottom weather strip 4 covered with the covering piece 16. 4 (i) and (j), which will be described later, and may be an overlapping region constituted by an outer peripheral surface 44 of the horizontal arm 12 and a hollow bottom weather strip 4 covering the outer peripheral surface 44. .

FIG. 4 shows an example of the shape of the contact surface 14 of the horizontal arm 12 when the overlapping structure area W is formed. In the present invention, the contact surface 14 of the horizontal arm 12 forming the overlapping structure region W can be formed in various shapes.

For example, as shown in FIG. 4A, the contact surface 14 of the horizontal arm 12 can be an inclined end surface having an angle θ in the left-right direction of the upper surface of the horizontal arm 12. Further, as shown in FIG. 4B, the contact surface 14 of the horizontal arm 12 may be an inclined end surface having an angle θ ′ in the left-right direction of the side surface of the horizontal arm 12. In addition, for the horizontal arm 12 having such an inclined end surface as the contact surface 14,
A bottom weather strip 4 having a contact surface 26 having a shape that can be connected to the contact surface 14 without a gap is adopted, and the overlap structure region W is configured.

As shown in FIGS. 4 (c) to 4 (f),
A rectangular covering piece 16 that covers the bottom weather strip 4 may be formed on the contact surface 14 of the horizontal arm 12. In these horizontal arms 12, the covering pieces 16 cover the bottom weather strip 4 to form the overlapping structure area W. More specifically, as shown in FIG. 4 (c), a coated piece 16 having one surface, as shown in FIG. 4 (d), a coated piece 16 having two faces, or as shown in FIG. A three-sided coated piece 16 or a four-sided coated piece 16 as shown in FIG. At this time, the covering piece 16 having one to three surfaces may be constituted by any surface of the upper surface, the lower surface, and both side surfaces, and is not particularly limited. Further, when the covering piece 16 is formed by two surfaces, it is preferable that the two surfaces be adjacent two surfaces. It may be configured with a side surface. When the covering piece 16 has three or four faces, a more water-tight structure can be obtained than in the case of two faces.

When the contact surface 14 of the horizontal arm 12 is circular or substantially circular, as shown in FIG. 4 (g), a covering piece 16 having a circular arc of a predetermined size may be formed. As shown in FIG.
May be formed.

Also, the hollow bottom weather strip 4
Is adopted, as shown in FIGS. 4 (i) and (j),
The horizontal arm 12 may have a rectangular or circular convex shape extending so that the abutment surface 14 is inserted into the hollow portion.

In the case of using the solid bottom weather strip 4 shown in FIG. 7 in the watertight structure 1 for a track and a lift according to the present invention, two adjacent surfaces extend so as to cover the bottom weather strip 4. Vertical covering pieces 17 and horizontal covering pieces 18 can be formed on the side and top surfaces of the horizontal arm 12 (see FIG. 3). The substantially L-shaped weather strip 11 is mounted on the corner portion 8 so as to cover the bottom weather strip 4, and can form an overlapping structure region W with the bottom weather strip 4. Further, in the watertight structure 1 of the present invention, the hollow bottom weather strip 31 shown in FIG.
Is used, the contact surface 14 of the horizontal arm 12
Is formed in a convex shape extending so as to be inserted into the hollow portion of the bottom weather strip 4, and the overlapping structure region W can be formed by inserting the contact surface 14 having the convex shape into the hollow portion of the bottom weather strip.

The above-mentioned overlapping structure area W is 5 in the horizontal direction.
It is preferably formed to have a length of about 80 mm.

According to the track-and-rail watertight structure 1 of the present invention, an excellent watertight structure can be obtained by forming the above-mentioned overlapping structure region W. In particular, in the present invention, it is preferable to form the above-described overlapping structure region W when the long bottom weather strip 4 having a total length of 3 m to 10 m is used. When such a long bottom weather strip 4 is used, it is difficult to cut the bottom weather strip 4 to a predetermined length. is there. Such variation in the length of the bottom weather strip 4 is caused by the contact surface 1 of the horizontal arm 12.
Although a gap is likely to be formed between the bottom weather strip 4 and the contact surface 26 of the bottom weather strip 4, in the present invention, even when the bottom weather strip 4 having a variation in length is used, the above-described overlapping structure area is used. Since W is formed with a predetermined length, it is possible to absorb such variations and maintain excellent watertightness. As a result, the horizontal arm 12
And the bottom weather strip 4 can be made watertight at a connection portion thereof, and a watertight structure can be provided in which water intrusion and dust intrusion are prevented.

As described above, in the present invention, by forming the overlapping structure area W in the horizontal arm 12, the L
The watertightness can be improved by eliminating the gap at the connecting portion between the U-shaped weatherstrip 11 and the bottom weatherstrip 4, and as a result, a watertight structure in which intrusion of water and intrusion of dust can be prevented can be achieved.

The vertical arm 13 extends in the vertical direction and is connected to the post weather strip 7. Such a vertical arm 13 is located on an extension of the post weather strip 7. The contact surface 15 of the vertical arm 13 and the post weather strip 7 having a long shape are formed.
Is provided in such a manner as to abut against the contact surface 27. Since the vertical arm 13 is connected to the post weather strip 7, a gap in the connected portion can be eliminated, and a watertight structure in which water intrusion and dust intrusion can be prevented.

The vertical arm 13 is the same as the horizontal arm 1 described above.
2, the overlapping structure region W can be formed between the post weather strip 7 and the post weather strip 7.
A coating piece or the like as shown in (j) can also be formed on the vertical arm 13. By forming the overlapping structure region W similar to the above-described horizontal arm 12 in the vertical arm 13, the water tightness between the substantially L-shaped weather strip 11 and the post weather strip 7 can be further improved, and water intrusion and dust can be prevented. A watertight structure that prevents intrusion of water can be obtained. Note that the vertical arm 13 is not necessarily overlapped from the viewpoint of easy attachment to the corner portion 8 and because the length is shorter than the above-described bottom weather strip 4 and the length is less likely to vary. May not be structured.

As described above, the substantially L-shaped weather strip 1 having the horizontal arm 12 and the vertical arm 13
1 is that, since at least one of the horizontal arm 12 and the vertical arm 13 and the bottom weather strip 4 form an overlapping structure area W, the horizontal arm 12 and / or the vertical arm 13 It is possible to eliminate the gap at the connecting portion with the bottom weather strip 4. As a result, the substantially L-shaped weather strip 11 can be attached to the corner 8 of the track tilt and eliminate the gap between the bottom weather strip 4 and the post weather strip 7 to improve water tightness. A watertight structure that prevents intrusion of water and intrusion of dust can be provided.

The substantially L-shaped weather strip according to the present invention includes a substantially L-shaped weather strip 11 'shown in FIG. 6, but preferably, the horizontal arm 12 is moved horizontally as shown in FIG. It is preferable that the extended portion and the portion of the vertical arm 13 extended in the vertical direction are formed so as to have a positional relationship overlapping in the corner region R of the substantially L-shaped weather strip 11. That is, as shown in FIG. 6, a virtual area P obtained by extending the horizontal orthogonal cross section of the horizontal arm 12 in the horizontal direction and a virtual area Q obtained by extending the vertical orthogonal cross section of the vertical arm 13 in the vertical direction are substantially L. Although the object of the present invention can be achieved even when the corner regions R of the U-shaped weather strip do not overlap, the virtual region P and the virtual region Q are formed at the corners of the substantially L-shaped weather strip 11 as shown in FIG. It is preferable to overlap in the region R. By using the substantially L-shaped weather strip 11 having such a configuration, the structure of the corner portion 8 constituting the watertight structure 1 can be simplified, and mounting can be easily performed.

The substantially L-shaped weather strip 11 'shown in FIG. 6 is specifically attached to the corner post 6 when the track tilt is separated from the floor frame 23 as shown in FIG. When the position of the post weather strip 7 from the floor frame 23 is away from the position of the bottom weather strip 4 attached to the bottom rel 2 from the floor frame 23, a corner between the corner post 6 and the bottom weather strip 4 is formed.
