Description

[Detailed description of the invention] This proposal relates to the improvement of an auxiliary gate that is attached to a truck bed by extending in the height direction of the gate, and aims to reduce assembly man-hours and weight. It is something.

Conventionally, this type of auxiliary gate consists of a plurality of wooden boards a forming the base of the gate, a chevron-shaped frame to which these wooden boards a are assembled, a long hinge C and a long hinge C, as shown in FIGS. It had a structure in which the long hinge back seat d, etc. were assembled by welding, bolting, etc.

The assembly procedure is explained below: 1) Cut the joint surface of the frame at 45 degrees, shape it to the outer dimensions of the side plate, and weld it to make the outer frame.

2) After briding the excess welding area above, apply anti-corrosion coating.

3) Arrange wooden boards a at required intervals inside the outer frame, and tighten these wooden boards a to the outer frame with bolts, nuts, etc. e to form a gate base.

4) Place the long hinge e on the front surface of the tilting base and the long hinge back seat d on the back surface, pass the bolt f from the back surface, and tighten it with the nut g on the back surface.

5) Attach the hook to one end of the upper wooden board a using bolts, nuts, etc.

6) Apply anti-corrosion coating to the entire surface.

It is.

Therefore, in the conventional structure, assembly processing is performed by different types of jobs such as machining, welding, and painting, which requires a large number of assembly steps and is troublesome.Also, since the outer frame is a welded structure, adjustment of assembly dimensions is required. There are problems such as difficulty in
Furthermore, the design of the entire gate is heavy, which increases its own weight, and the long hinge seat d protrudes from the inside of the gate, which is dangerous because it can easily damage the cargo.

This proposal was devised in view of the above problems, and aims to eliminate the drawbacks of the conventional method by connecting the longitudinal panel members that constitute the gate base using lightweight rectangular long hinges made of aluminum alloy. This is the purpose.

Next, an embodiment of the present invention will be described with reference to FIGS. 3 and 4.

In the figure, reference numeral 1 denotes a long hinge made of aluminum alloy that is pivotally attached to the upper end of the main gate 2, and has a rectangular frame portion 1a and a hinge portion 1.
A plurality of recesses 1c, 1c... are formed at appropriate intervals on one surface of the rectangular frame portion 1a, that is, the surface located on the inside of the gate, and a plurality of recesses 1c, 1c... are formed at appropriate intervals on the inside. A reinforcing horizontal rib 1d and a protrusion 1e for holding a panel member, which will be described later, are formed at the location.

Reference numerals 3 and 4 denote an upper panel member and a lower panel member that penetrate the frame of the long hinge 1 and constitute the gate base, and like the long hinge 1, they are made of aluminum alloy, and these panel members 3 , 4 consists of two hollow parts 3as3b or 4at4b each having a rectangular cross section and a flat part 3c or 4c extending from one side of the hollow part and connecting the rain hollow parts 3a*3b or 4at4b, They are shaped like so-called glasses.

Reference numeral 5 denotes a channel-shaped frame attached to the longitudinal end of the panel member 3.4, and 5 is attached to the upper end of the frame 5 in the height direction and the longitudinal end of the panel member 3.4. The arc-shaped corner fittings, 7 are latch fittings.

Next, the assembly process of the present invention will be explained.

First, the upper panel member 3 and the lower panel member 4 cut to arbitrary dimensions are placed at an appropriate interval, and the long hinge 1 is slid from the ends of these panel members 3 and 4, and the long hinge 1 is cut to an arbitrary size. position.

Next, the frame 5 and the arc-shaped corner metal fittings 6 are fitted into the lengthwise ends of the panel members 3 and 4, holes are made in predetermined positions of the frame 5 and the recess 1c of the long hinge 1, and rivets are set. 8, bolts 9, nuts 10, and other fasteners to fix each part to form a gate base.

At this time, the head of the rivet 8 or bolt 9 is completely inserted into the recess 1c.

Furthermore, after attaching the latch 7 to the upper end of the gate base with bolts, nuts, etc. 11, it is pivoted to the end of the main gate 2 in the height direction via the hinge portion 1b of the long hinge 1. Complete.

According to the present invention configured as described above, the following excellent effects can be obtained.

■) Since it can be assembled by simple machining (cutting, drilling, riveting, bolting, nut tightening, etc.), it is economical because the assembly man-hours can be reduced (about 50 times less).

2) It has a rectangular frame shape and uses integral hinges, so it is highly rigid.

3) Rounding of the upper end can be easily done by attaching arc-shaped corner metal fittings (to prevent tearing of the hollow sheet).

4) Since aluminum alloy shaped material can be used as the main part, it is lightweight (approximately 40% lighter), easier to assemble and operate, and has excellent corrosion resistance.

5) Since most of the parts are housed within the member, there are no protrusions on the surface of the gate, improving safety.

6) Depending on the application or customer's requirements, any number or shape of panel members can be attached to the transverse ribs or protrusions of the long hinge, making it possible to diversify the design.

In addition, although the above embodiment shows an example in which the panel member is held by the protrusion, the panel member is held by the horizontal rib in the same way.
