Description

[Detailed Description of the Invention] This invention relates to a lower structure for a gate which is rotatably attached to the floor of a truck or the like, for example, by stacking and connecting a plurality of hollow sections with through bolts.

In other words, the gist of this invention is to prevent connectors such as through bolts from being exposed to the outside and being corroded by closing the lower end opening of the hollow member located at the lowest end of the gate with a lid. At the same time, it is possible to prevent water from entering the loading platform through the gap between the gate and the vehicle floor by watertight means such as a watertight backing fitted to the lid and a water-tight ridge protruding from the lid. The present invention attempts to provide a lower structure for the tilting mechanism, which is characterized by the following.

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

Figure 1 shows the tilt 1 having the structure of this invention on track A.
This is a perspective view showing the state in which it is mounted around a loading platform B. The gate 1 is constructed by stacking and connecting a plurality (three shown in the drawing) of hollow sections 2 with through bolts 3 and nuts 4, which will be described later. , and a side end cover 5 is attached to the side end portion thereof.

FIG. 2 is a longitudinal sectional view showing the first embodiment of this invention, with the gate 1 mounted on the floor C of the loading platform B.

In this case, an opening 6 for inserting the through bolt 3 is provided at the lower end of the hollow member 2 located at the lowest end of the gate 1, and a draining protrusion 7 that abuts the outside of the floor frame C hangs down. The opening 6 is provided with a hinge 8 which rotatably attaches the gate 1 to the floor frame C in addition to the through bolt 3 and nut 4. A nut 10 screwed onto this bolt 9 is inserted.

Further, longitudinally extending retaining portions, that is, engaging grooves 11, 11 having a substantially C-shaped cross section are formed facing each other on both inner edges of the opening 6 along the longitudinal direction of the hollow member 2.

Note that the engagement groove 11 is formed so that its upper and lower portions are symmetrical with respect to its center line.

Reference numeral 12 denotes a lid body, on both sides of which in the longitudinal direction are formed engaging edges 13, 13 with swollen tips that can engage with the engaging grooves 11.11, and Longitudinal through fittings 114a and 1 are provided on the upper and lower surfaces, respectively.
4b are formed, and these attachment grooves 14a and 14b are formed.
The mounting located on the lower surface is installed in the groove 14b in the floor portion C.
A watertight backing 15 that can abut on the top is fitted.

Furthermore, a draining ridge 16 is provided in a protruding manner approximately in the middle of the top surface of the lid 12.

In this case, in the first embodiment, the draining ridge 16 does not serve its main purpose, that is, to prevent water from entering the loading platform from between the gate 1 and the floor frame C (in the first embodiment, Draining protrusion 7 of Aori 1 is used instead),
It serves to prevent water from entering through the gap between the engagement groove 11 of the hollow member 2 and the engagement protrusion 13 of the lid 12 due to capillary action.

Engagement protrusion 13.13 of lid body 12 configured as described above
is configured so that it can be engaged with the engagement groove 11.11 even when it is turned upside down, and the opening 6 of the hollow member 2 is closed by selecting the upper and lower surfaces of the lid 12. .

Even when the opening 6 is closed in either state, the engagement between the engagement groove 11 and the engagement protrusion 13 restrains each other in the direction perpendicular to the longitudinal direction.

The strength of the gate 1 can be maintained by preventing the opening 6 of the hollow member 2 from expanding or deforming inwardly. Corrosion of the connector can be prevented.

Note that the lid body 12 is prevented from shifting in the longitudinal direction by the covers 5 on both sides of the gate 1.

FIG. 3 is a vertical sectional view of the main part showing the second embodiment of this invention.
This is a case where a part of the gate 1 is made to protrude outward from the floor frame C and is mounted.

In this case, the opening 6 is closed with the lid 12 by positioning the draining ridge 16 provided on the lid 12 downward;
In this case, the attachment located on the lower surface is such that the watertight backing 15 is fitted into the groove 14a so that the watertight backing 15 comes into contact with the floor frame C.

Therefore, according to this second embodiment, the water draining ridge 16 prevents water from entering the loading platform side through the gap between the gate 1 and the floor frame C, and in the unlikely event that water crosses the draining ridge 16 and enters the gap. Even if water were to enter, the watertight backing 15 can completely prevent water from entering.

FIG. 4 is a vertical sectional view of a main part of a third embodiment of this invention, in which draining ridges 16 and 16' are provided on the upper and lower surfaces of the lid 12, respectively.

In this case, by shifting the protruding positions of both draining ridges 16 and 16' in the width direction of the lid body 12, it is possible to cope with cases where the mounting condition of the gate 1 is different, that is, when the protruding condition from the floor frame C is different. In addition, it is possible to prevent water from entering through the gap between the engagement groove 11 and the engagement protrusion 13 by capillary action by the draining protrusion 16' located in the opening 6. .

In the second and third embodiments, the same parts as in the first embodiment are designated by the same reference numerals, and the explanation thereof will be omitted.

Further, in the above embodiment, the cross section of the engaging groove 11 provided in the opening 6 is approximately C-shaped, and the cross section of the engaging protrusion 13 provided in the lid body 12 is a bulge having the same shape as the cross section of the engaging groove 11. However, the shape is not necessarily limited to this shape. For example, the cross section of the engaging groove 11 may be made into a hook shape, and the cross section of the engaging protrusion 13 may be made into an inverted hook shape that can be engaged with this hook shape. It can also have any shape, and the shape is arbitrary.

Furthermore, the same effect can be obtained by forming the engaging portion between the opening 6 and the lid 12 in the opposite way, that is, by forming a ridge on the opening 6 and forming a groove portion on the lid 12 that engages with the ridge. It is effective.

As explained above, according to this invention, the opening for inserting a connecting tool such as a through bolt provided at the lower end of the lowermost hollow member constituting the gate is closed by the lid, so that the gate is closed. Eliminating the through hole for inserting the connector during assembly not only gives the door a cleaner appearance, but also prevents the connector from corroding, and also prevents the opening from expanding outward or moving inward. This has the excellent effect of preventing deformation, etc., and improving the strength of the entire gate.

In addition, the lid body has grooves on its upper and lower surfaces for attaching the watertight backing, and has draining ridges on at least one side so that the opening can be closed by selecting the upper and lower surfaces. The mounting of the lid body can be changed depending on whether it is completely mounted on the floor frame or when it is projected outward from the floor frame, and in either situation, the mounting is fitted into the groove. The watertight backing that comes into contact with the floor frame has the excellent effect of maintaining watertightness even in the gap between the door and the floor frame.

Moreover, according to the structure of this invention, it is possible to eliminate the troublesome work of riveting the cover plate to the side of the gate in the conventional gate of this kind, so the assembly work can be easily performed, and Excellent effects such as the ability to easily repair and inspect the connector can be obtained.
