DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an armrest device used in a cargo-handling vehicle, for example, for operating a cargo-handling operation lever by placing an arm to reduce the number of operations.

[0002]

2. Description of the Related Art Conventionally, in a cargo handling vehicle, for example, as shown in FIG.
An armrest device 15 is provided beside the seat 12 and near the cargo handling operation lever 11. At that time, the armrest device 15 is configured so that the height of the armrest 16 can be adjusted according to the physique of the operator. Various configurations are provided for the height-adjustable armrest device 15.

That is, in the armrest device 15 shown in FIGS.
Is a rectangular plate-like shape, and a square rod-like body 17 is hung from the center of the lower surface. Further, a square tubular member 20 is provided on the fixed side, and a square rod 17 is inserted into the square tubular member 20 so that the armrest 16 can be moved up and down. Then, the fixing bolt 21 screwed to one side plate of the square cylindrical member 20 is brought into contact with the square rod 17, and the square rod 17 is pressed against the inner surface of the other side plate of the square cylindrical member 20. , And can be fixed at a desired elevation position.

The armrest device 15 shown in FIG. 4B has a plate-like member 22 on the fixed side, and a plate-like member 23 on the armrest 16.
The armrest 16 has a plate-like body 23 formed of a plate-like member 2.
2 so as to be able to move up and down by sliding. Then, the fixing bolt 21 is passed through the elongated hole 24 formed in two places of the plate-like body 23 from the outside, and then screwed to the plate-like member 22, so that the fixing bolt 21 is moved up and down at a desired elevating position. It can be fixed.

In the armrest device 15 shown in FIG. 4 (c), one side surface of the square bar 17 is formed on a sawtooth surface 26, and a sawtooth member 27 provided at the tip of a fixing bolt 21 is provided. By meshing with the saw tooth surface 26, it can be fixed at a desired elevating position.

The armrest device 15 shown in FIG. 4D is provided with a lower quadrangular tubular member 28 that guides the lower portion of the quadrangular rod 17 up and down below the quadrangular tubular member 20.

[0007]

However, in the above-mentioned conventional structure, the armrest device 15 shown in FIGS. 3 and 4A is centered on the position of tightening (pressing) by the fixing bolt 21. There is a problem that rattling in the lateral rotation direction is apt to occur, giving the operator discomfort.
On the other hand, each of the armrest devices 15 shown in FIGS. 4B, 4C, and 4D can prevent rattling, but on the other hand, operability, structure, and the like. There was a problem with the price.

That is, in the armrest device 15 shown in FIG. 4B, since the two fixing bolts 21 must be operated, the operation is troublesome and cannot be performed easily. Armrest device 1 shown in c)
5 is a meshing type having a complicated configuration, so that the processing cannot be easily performed and is expensive. Further, the armrest device 15 shown in FIG.
8 will cause a problem in the mounting location.

An object of the present invention is to provide an armrest device which is simple and inexpensive in operability and structure, and which prevents rattling.

[0010]

According to one aspect of the present invention, there is provided an armrest device comprising: a fixed member; an armrest which can be moved up and down with respect to the fixed member; An armrest device comprising the armrest fixing operation tool, wherein the fixed side member includes:
The support body from the armrest has a receiving body that can be abutted from the side, the receiving surface of this receiving body is formed in a V-shaped cross section, and the fixing operation tool presses the support body against the receiving surface. It is characterized by being fixed.

Therefore, according to the first aspect of the present invention, in order to adjust the height of the armrest, first, the fixing operation tool is loosened to release the pressing of the support body against the receiving surface. Then, by raising and lowering the armrest and setting the desired height position, the fixing operation tool is tightened, whereby the support body can be pressed against the receiving surface, so that the support body is held between the receiving body and the fixing operation tool. Thus, the armrest can be fixed at a desired height position. At that time, the armrest is fixed by pressing a pair of portions (two portions) of the support body against a pair (two portions) of the receiving surface having a V-shaped cross section, that is, two separate portions. Is performed as the pressure contact position, so that the support body can be completely prevented from rattling.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.
A description will be given based on FIGS. Armrest device 1
Is composed of a fixed member 2, an armrest 7 that can move up and down with respect to the fixed member 2, and a fixing bolt (an example of a fixing operation tool) 9 of the armrest 7. The fixed side member 2 is composed of an inverted L-shaped guide 3 and a receiver 4 having a V-shaped cross section. The armrest 7 has a rectangular plate shape, and a square rod-like body (an example of a support body) 8 hangs from a central portion of the lower surface thereof.

The upper horizontal plate portion 3a of the guide body 3 is formed with a rectangular hole 5 through which the square rod-like body 8 is inserted so as to be able to move up and down, and the vertical plate portion 3b is formed with a horizontal screw hole 6. Have been. The receiving body 4 is provided so as to hang down from the lower surface of the free end of the upper horizontal plate portion 3a so that the square rod-shaped body 8 of the armrest 7 can be freely contacted from the side. At this time, the receiving surface 4a of the receiving body 4 is formed in a V-shaped cross section. The fixing bolt 9 can be screwed into the screw hole 6 from the outside, and is configured so as to be pressed and fixed to the receiving surface 4a by the screwing.

The operation of the above embodiment will be described below. To adjust the height of the armrest 7, first, the fixing bolt 9 is loosened to release the pressing of the square rod 8 against the receiving surface 4a. Next, the armrest 7 is held up and down by one hand, and the fixing bolt 9 is tightened (screwed) by the other hand while maintaining the desired height position. By this tightening operation, the square rod 8 is pressed against the receiving surface 4a, whereby the square rod 8 is held between the receiving body 4 and the fixing bolt 9, and the armrest 7 is fixed at a desired height position. I can do it.

According to this embodiment, the armrest 7 is fixed by a pair of (two) corner portions (two portions) of the square rod 8 on the receiving surface 4a having a V-shaped cross section. Are pressed against each other, that is, two separate positions are used as pressure contact positions, so that the square rod-shaped body 8
Can be performed in a state where rattling is completely prevented. Moreover, since it is only necessary to adopt a receiving body 4 having a V-shaped cross section as the receiving body 4 for receiving the fixing bolt 9, the structure can be provided simply and inexpensively. The operation of the fixing bolt 9 can be simply and easily performed.

In the above-described embodiment, the square rod 8 is shown as a support, but it may be a round rod or a plate. In the embodiment described above, the fixing bolt 9 is shown as the fixing operation tool, but this may be a cam lever type or the like.

[0017]

According to the first aspect of the present invention, after the armrest is raised and lowered, the fixing operation tool is tightened, whereby the support body is pressed against the receiving surface, and the support body is fixed to the receiving body. The armrest can be fixed at a desired height position. At that time, since the armrest is fixed by pressing a pair of portions of the support body against a pair of surfaces of the receiving surface having a V-shaped cross section, that is, by using two separated portions as press-contact positions, It can be performed in a state where rattling of the body is completely prevented. Moreover, since it is only necessary to adopt a receiving body having a V-shaped cross section as a receiving body for receiving the fixing operation tool, the structure can be provided simply and inexpensively. Since the operation is sufficient, the operation can be performed easily and easily.
