JPH057586U - Draining structure at the bottom of the track and trailer - Google Patents

Abstract

(57) [Summary] (Correction) [Purpose] The bottom of the aluminum section rail at the bottom of the rail is not limited to the seal member only at the joint between the bottom of the truck and trailer and the floor frame. The floor frame is also joined to the section, so that the stress acting because the gap between the lower part of the fan and the floor frame is momentarily changed due to vibration during running, sudden curve, etc. is applied only to the soft seal member. It is possible to prevent the seal member from deteriorating by acting on a part of the lower end surface of the hard aluminum die material rail instead of concentrating on it. [Structure] A plurality of aluminum mold material rails 2 extending in the longitudinal direction
In a fan of a truck or a trailer configured by fitting and connecting 4 in a layered manner, at least a part of the lower end surface of the aluminum profile rail at the lowermost stage when the fan is erected is at least part of the floor frame 18. A groove that is pivotally attached to the side surface of the floor frame via a hinge 32 so as to overlap with the upper surface, and that projects downward from the other portion of the lower end surface of the lowermost aluminum profile rail. A seal member is attached to the portion, and the seal member is configured to abut and join with the upper portion of the side surface of the floor frame when the fan is erected.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a draining structure for a lower portion of a truck or a trailer.

[0002]

[Prior Art]

 Regarding the draining structure for preventing water from entering when the fan is erected by installing a seal member between the lower part of the truck and the trailer and the floor frame, for example, actual opening 64-26583, actual opening 2- Various ideas have been conventionally made as shown in 99046 and 3-32572.

[0003]

[Problems to be solved by the device]

 In the above conventional technique, a seal member is interposed between the lower portion of the fan and the floor frame, but the joint between the lower part of the fan and the floor frame is only a soft seal member such as rubber. However, the parts other than the seal member are not joined or polymerized.

On the other hand, when a truck or trailer fan is erected and cargo is loaded and covered with a hood for transportation, a gap between the lower part of the fan and the floor frame is generated due to vibration during driving, sudden curving, or the like. Since the stress suddenly changes and the stress is concentrated on the soft seal member each time, the seal member may deteriorate quickly and cannot be used for a long period of time.

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to a truck or trailer fan, which is constructed by fitting and connecting a plurality of aluminum mold material rails extending in the longitudinal direction in layers, when the fan is set up. At least a part of the lower end surface of the lowermost aluminum section rail is rotatably pivoted via a hinge with the outer side surface of the floor frame so as to overlap with the upper surface of the floor frame, and A seal member is attached to a groove portion projecting downward from another portion of the lower end surface of the lower aluminum profile rail, and the seal member is an upper portion of a side surface of the floor frame when the fan is erected. By joining the floor frame to the floor frame, the bottom part of the bottom aluminum mold rail is not limited to the seal member. As a result, the gap between the lower part of the fan and the floor frame changed instantaneously due to vibration during driving, sudden curving, etc. The stress acting on the softer sheet - without concentrating only on the seal member, an aluminum-type material Les have hardness - are those to prevent degradation of the seal member - sheet by the action and a part of the lower end surface of the Le.

【Example】

 Fig. 1 is a view taken along the line A-A in Fig. 2 and shows a draining structure of a lower portion of a truck or trailer according to the present invention. Fig. 2 is an overall perspective view of an ordinary truck with a fan attached to the floor. 3 shows a state in which a seal member is attached at a portion B of FIG. 1, FIG. 4 shows another embodiment of the present invention, and FIG. 5 shows a conventional drainage structure of a lower part of the fan. Indicates.

As shown in FIG. 2, fan 14 and 14 are pivoted vertically on hinges 16 and 16 at the edge of floor 12 of the rear cargo bed of ordinary truck 10 via hinges 16, 16, 16 ... FIG. 5 shows the conventional structure of the AA arrow section as worn.

In the conventional structure shown in FIG. 5, the fan 14 is composed of an aluminum profile rail extending in the longitudinal direction, and the edge of the floor 12 is surrounded by a floor frame 18. The side surface and the fan 14 are pivotally attached to each other via a shaft 20 so as to be vertically rotatable.

Then, a seal member 22 is attached to a vertical strip provided on the lower end of the inner side surface of the lowermost aluminum mold material rail, and only the tip of the seal member 22 is attached to the floor frame 18 Since it is configured so as to be able to come into contact with the bottom of the fan 14, when the fan 14 is erected and the cargo is loaded and covered with a hood for transportation, vibration and sudden curving during traveling may cause a lower part of the fan 14 and the floor frame. Since the gap between the seal member 18 and the soft contact member 18 changes instantaneously and stress acts intensively on the soft seal member 22 each time, the seal member 22 deteriorates quickly and cannot be used for a long period of time. This was often the case.

In order to solve the above-mentioned problems, the present invention, as shown in FIGS. 1 and 3, comprises a plurality of aluminum mold material rails 24 extending in the longitudinal direction, which are fitted and connected in layers to form a track or tray. -In the blade 23 of the la, a part 30 of the lower end surface 28 of the aluminum-shaped material rail 26 at the lowest stage when the blade 23 is erected is constructed so as to be joined to the upper surface of the floor frame 18. A seal member 36 is rotatably pivotally attached to the outer surface of the side through a hinge 32, and a seal member 36 is provided in a groove portion 34 projecting downward from another portion of the lower end surface 26 of the lowermost aluminum mold material rail. The seal member 36 is mounted so as to come into contact with the upper part of the side surface of the floor frame 18 when the fan 23 is erected.

FIG. 4 shows another embodiment of the present invention. In this embodiment, most of the lower end surface of the aluminum-shaped material rail 29 at the lowermost stage when the fan 23 is erected is located on the upper surface of the floor frame 18. In order to be joined, a side outer surface of the floor frame 18 is pivotally rotatably attached via a hinge 40, and a seal member 36 is attached to a groove portion 34 projecting downward from the inner end of the lower end surface. The seal member 36 is configured to abut and join with the upper side surface of the floor frame 18 when the fan 23 is erected.

[Effect of the device]

 As described above, according to the present invention, at least a part of the lower end surface of the aluminum profile rail at the lowermost stage when the fan is erected is formed with the outer side surface of the floor frame and the hinge so that the lower end surface overlaps with the upper surface of the floor frame. The aluminum member is rotatably pivoted through the seal member, and a seal member is attached to a groove portion projecting downward from the other portion of the lower end surface of the lowermost aluminum mold member rail. By abuttingly joining to the upper part of the side surface of the floor frame when the fan is erected, the aluminum part of the lowermost stage is not used as the joint between the lower part of the fan and the floor frame. A part of the lower end surface of the rail is also joined to the floor frame, which causes a stress that acts on the gap between the lower part of the rail and the floor frame due to an instantaneous change due to vibrations during driving or sudden curves. Do not concentrate only on the soft seal member, but also on a part of the lower end surface of the hard aluminum profile rail. Therefore sheet - it is possible to prevent the deterioration of the seal member.
