Description

The present invention relates to a base bracket for standing uprights attached to a tilt of a flat body type truck.

When a load is placed on the loading platform of a flat body type truck, a platform is built on the loading platform, and the load is loaded thereon. The front and rear length is when loading a long object such as a ladder, stepladder, or reaper that protrudes forward and backward within the legal limit. In particular, in the case of a light truck having a short front and back length of about 1940 mm, it is often seen that such a platform is provided. Such a gantry is required to be easily detachable and safe (strong).

There are following Patent Documents 1 and 2 as prior documents of such a thing. Reference 1 is a frame of a rainproof sheet, which passes a bar to the center of the front torii and the rear wing, and hangs the rainproof sheet on a gable roof. It can be assembled relatively easily, but it is not removable. In addition, it is not a platform for loading luggage. Document 2 is a frame of a covering sheet that covers a load, but has a complicated shape and is not easy to install. Above all, it doesn't use the tilt, nor is it a platform for loading luggage.

By the way, the gantry is usually composed of a column (vertical beam) and a horizontal beam, but if it can be easily assembled, it is to use a tilt other than the floor surface. For example, the base metal for standing upright is not fixed by welding or the like, but can be attached and detached with one touch. However, even with the height of the tilt, there are differences due to assembly errors and differences in manufacturers. In such a case, it is desirable to be able to do it with simple adjustment.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base bracket for standing uprights that can be mounted using a flat body type truck, in particular, a light truck platform, and can be installed with simple adjustment even if the dimensions of the rack are slightly different. It is what I did.

Under the above-mentioned problems, the present invention provides a base bracket for standing uprights attached to the inner surface of a flat body type truck according to claim 1, and an upper base metal fitting attached to the upper part of the cage. The upper base bracket is connected to the upper base bracket through a length-adjustable connection structure, and the lower base bracket is attached to the lower portion of the cage. The column is held upright by the upper base bracket and the lower base bracket. The present invention provides a base bracket for standing uprights to be attached to a tilt of a flat body type truck characterized by the following.

Further, according to the present invention, in the above invention, the upper base metal fitting described in claim 2 has an outwardly opened U-shaped locking portion locked to the upper surface of the cage, and both sides below the U-shaped locking portion. A lower holding portion similar to the upper holding portion, the upper holding portion holding the support in this space. There is provided a configuration having an L-shaped insertion part that is inserted in a gap between the lower part and the lower holding part and the floor.

Furthermore, the present invention is the above invention, wherein the connecting mechanism according to claim 3 is provided with a lower projecting plate at the lower end of the upper base metal fitting when the upper base metal fitting and the lower base metal fitting are vertically connected. An upper overhanging plate that overlaps the lower overhanging plate is provided at the upper end of the lower base bracket. A screw hole is made in the lower overhanging plate, and a screw is screwed into this screw hole from below to form an upper overhanging plate. A configuration is provided in which the length of the upper base metal fitting and the lower base metal fitting is adjusted by turning the screw and turning the upper base metal fitting and the lower base metal fitting relatively close to each other.

According to the first aspect of the present invention, it is limited members such as the upper and lower base metal fittings that stand the column. In addition, since these can be easily attached to the cage, they can be attached when necessary and removed when not needed. According to the second and third aspects, since the height of the upper and lower base metal fittings can be adjusted with a simple structure, even if the height of the tilt is slightly different, it can be dealt with.

It is a front view of an upper base metal fitting and a lower base metal fitting. It is AA sectional drawing of FIG. It is a B arrow line view of FIG. It is the side view which put up the support | pillar combining upper and lower base metal fittings. It is a perspective view similarly. It is a rear view of the light tiger which set the mount which consists of a support | pillar and a horizontal cross in the loading platform. It is a partial side view which shows the other example of the assembly | attachment of a crosspiece. It is a partial cross-sectional side view of the tilting, base metal fitting, and support | pillar which show another example.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings, taking a light truck (hereinafter referred to as a light tiger) as an example. 1 is a front view of an upper base bracket (hereinafter referred to as an upper bracket) and a lower base bracket (hereinafter referred to as a lower bracket), FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 3 is an arrow B in FIG. Although it is a view, the upper metal fitting 1 is attached to the inner surface of the pallet 2 of the loading platform described later. The upper metal fitting 1 is formed by molding a metal plate material such as an aluminum plate. The upper metal fitting 1 has an outwardly protruding U-shaped locking portion 3 that hooks on the upper surface of the cage 2 and is located below the U-shaped locking portion 3. The base plate portion 4 has an upper holding portion 5 that protrudes inward from both sides, bends toward the center, and partially extends to the other side, and a lower projecting plate 6 that protrudes toward the U-shaped locking portion 3 at the bottom. is there.

The lower metal fitting 7 is also a similar plate material, and an upper overhanging plate 8 that overlaps with the lower overhanging plate 6 is formed at the upper portion, bent inward from the middle to form a substrate portion 9, and the upper portion is held on the substrate portion 9. A lower holding portion 10 similar to the holding portion 5 is formed, and an L-shaped insertion portion 11 that protrudes toward the upper projecting plate 8 is formed at the bottom.

Next, the case where the upper metal fitting 1 and the lower metal fitting 7 are combined and attached to the tilt 2 will be described. 4 is a side view thereof, and FIG. 5 is a perspective view. The upper overhanging plate 8 of the lower metal fitting 7 is overlapped on the upper overhanging plate 6 of the upper metal fitting 1, and the both are engaged with each other. Then, the U-shaped locking portion 3 of the upper metal fitting 1 is hooked on the upper surface of the cage 2, and the L-shaped insertion portion 11 of the lower metal fitting 7 is inserted into the gap between the floor 12 of the loading platform and the cage 2. Since the hinge 2 is provided with a hinge (not shown) between the tilt 2 and the floor surface 12, there is a certain gap, so that there is enough space for this insertion.

At this time, a screw hole 13 is formed in the center of the lower overhanging plate 6, a screw 14 is screwed into the lower overhanging plate 6 from below, and a tip thereof is applied to the upper overhanging plate 8. Then, by turning the screw 14 and pulling the U-shaped locking portion 3 and the L-shaped insertion portion 11 together, the upper metal fitting 1 and the lower metal fitting 7 are completely fixed to the tilt 2 (for the sake of safety, the screw 14 is loosened). The locking nut 15 is screwed in). Specifically, if the screw 14 is turned in the protruding direction, the upper metal fitting 1 is pulled downward, and if it is turned in a shorter direction, it is loosened upward. This configuration is a mechanism for adjusting the difference in the distance (length, height) between the U-shaped locking portion 3 of the upper metal fitting 1 and the L-shaped insertion portion 11 of the lower metal fitting 7, and is hereinafter referred to as a connection mechanism 16. This is to cope with the height of the top and bottom surfaces of the tilt 2 slightly depending on the assembly error and the vehicle type.

If this operation is completed, a column (vertical beam) is inserted into the inner space formed by the upper holding part 5 and the lower holding part and received by the floor 12. Thus, the column 17 can be fixed and erected, but in some cases, the column 17 may be stopped from the side with a screw (not shown). In addition, in this example, the space of the upper holding part 5 was made into a square, and the support | pillar 17 inserted in this was made into a square pipe similarly, However, It is not limited to this.

In order to use the frame to be set on the loading platform, it is necessary to attach the crosspiece 18 to the support 17. Although the attachment of the horizontal beam 18 is not particularly limited, normally, a horizontal hole 19 into which the horizontal beam 18 can be inserted is formed in the inner surface of the upper part of the vertical beam, and the horizontal beam 18 is inserted into this and fixed with a screw 20. At this time. A nut or the like 18a may be welded to the end side of the cross rail 18 and the screw 20 may be tightened and stopped from the outer surface. At this time, the upper surface of the column 17 is set higher than the horizontal rail 18. This is to prevent the luggage from falling outward due to vibration or the like when a ladder or the like as a load is placed. In addition, although the support | pillar 17 and the crosspiece 18 may be attached integrally by welding etc., what can be divided | segmented is preferable by storage etc. These struts 17 and the horizontal rails 18 are not limited to those constituting the gantry, and may be a basic frame such as a sheet. Further, only the support column 17 may be provided.

By the way, according to the above configuration, since the sizes of the horizontal hole 19 and the horizontal beam 18 are substantially the same, the horizontal beam 18 longer than the interval between the columns 17 does not enter in principle after the column 17 is erected. Therefore, after the column 17 and the crosspiece 18 are assembled in a T shape outside, both the columns 17 must be inserted into the upper holding unit 5 and the lower holding unit 10 at the same time, which is quite difficult. FIG. 7 is a partial side view of another example for improving this, but in this example, a vertical groove 19a is formed in which the horizontal rail 18 can be inserted into the horizontal hole 19 and opened upward. According to this, the horizontal rail 18 can be lowered and attached after the column 17 is erected by removing the screw 20. Further, the horizontal positions of the horizontal rails 18 are also aligned.

In addition, the hole through which the screw 20 on the outer surface of the column 17 is passed can also be a vertical groove (not shown). According to this, what loosely assembled the screw 20 to the crosspiece 18 can be inserted from above, and the assembly is very easy. Even in such a case, since the load by the load is downward, there is no shortage in strength. Above all, in the case where the column 17 described later is made to be telescopic, the left and right columns 17 can be expanded and contracted and the horizontal rail 18 can be assembled freely.

The upper and lower metal fittings 1 and 7 are basically a pair of left and right, but it is not always necessary to provide the front and rear as shown in FIG. 6, and only one (in this case, the rear) may be provided. Further, the height is usually higher than the roof 22 of the driver's seat 21, but it may be lower (in that case, the front is passed diagonally over the torii 23). Of course, a rope or the like is used to stop the luggage on the side rail 18 or the torii gate 23.

FIG. 8 is a partial cross-sectional side view of another example. In this example, the height of the column 17 can be adjusted. In other words, keep it low all the time, and extend it when necessary. If it is set low, there is not much influence on loading and unloading of luggage, and there is almost no hindrance to opening and closing the cage 2, so there is no need to remove it. It should be noted that once the upper and lower metal fittings 1 and 7 are attached, they are hardly in the way of loading / unloading of luggage and opening / closing of the cage 2.

The telescopic structure of the column 17 may be any type, but a telescopic type is suitable. FIG. 7 is a two-stage type, or the upper column 17b is placed in the lower column 17a, and the upper column 17b is pulled out and used when necessary. In this case, the upper support column 17b must be stopped, but for example, the pin 24 may be passed through the lower support column 17a on the lower side of the upper support column 17b. However, it is not limited to this, and it may be one that is screwed. Further, the number of steps is not limited to two, and the stopping position is not limited to one.
