Embodiments of the present invention will be described below with reference to the accompanying drawings.

(First Embodiment) In FIGS. 1 and 2,
For example, on the outer body wall 1 of an industrial vehicle such as a forklift,
A through hole 2 is provided. The louver 3 inserted into the through hole 2 has a flange portion 4 in contact with the outer surface of the vehicle body outer wall 1,
The louver legs 5 are sunk toward the vehicle body from the vehicle body outer wall 1. In the present embodiment, the louver legs 5 are composed of mooring legs 6 which are substantially equally arranged at four locations on the circumference, and guide legs 7 which are disposed on both sides of the mooring legs 6, respectively. At the tip of the mooring leg 6, a mooring claw 8 for retaining is formed. A part of the outer peripheral surface of the louver 3 is formed as a flat surface 10, and the through hole 2 is also provided with a flat surface (not shown) that engages with the flat surface 10. The positioning device is configured to maintain the position. On the inner peripheral side of the louver 3, rainwater or the like is prevented from entering, but a plurality of swash plates 11 through which air can freely flow.
Are arranged. The distal end of the duct 12 is fitted to the louver leg 5. On the other hand, although not shown, the base end of the duct 12 is provided at a desired location for introducing outside air in the vehicle body, for example, a room for accommodating heat-generating components requiring air cooling (that is, a controller storage room in the case of a battery-type forklift). Are in communication. At the tip of the duct 12, a mooring recess 13 capable of mooring the mooring claw 8 is provided at a position corresponding to the mooring claw 8. When the distal end of the duct 12 is fitted to the louver leg 5, the mooring claw 8 is fitted into the mooring recess 13, at which point the distal end surface 14 of the duct 12 and the flange of the louver 3 are fitted. 4, the duct 12 is fixedly attached to the vehicle body outer wall 1 with the vehicle body outer wall 1 sandwiched therebetween.

The operation of the present apparatus will be described below. When assembling this device, first, the louver 3 is placed on its flat surface 1.
0 is inserted into the through hole 2 until the flange portion 4 comes into contact with the outer surface of the vehicle body outer wall 1 while being aligned with the flat surface of the through hole 2.
At this time, the insertion is guided by the guide legs 7, and the mooring legs 6 bend once to the inner peripheral side so that the mooring claws 8 pass through the through holes 2. When the distal end of the duct 12 is continuously inserted into the louver leg 5 from this state, the insertion is similarly guided by the guide leg 7, and the mooring leg 6 is bent once to the inner peripheral side and then inserted. Mooring claw 8 is mooring recess 13
And the mooring of the duct 12 and the louver 3 is achieved. In this state, the duct 12 is mounted and fixed to the vehicle body outer wall 1 as described above. The base end of the duct 12 is connected to a desired portion of the vehicle body for introducing outside air.

In the thus assembled apparatus, the outside air sucked through the louver 3 from between the swash plates 11 flows through the duct 12 and is introduced into the vehicle body at a desired location for introducing outside air. Introduced to. On the other hand, in the louver 3, rainwater or the like is prevented from entering due to the shielding action of the swash plate 11.

The effects that can be expected from the first embodiment will be described below. (1) Compared with the conventional apparatus, a tubular mounting body, a ring band, a bolt, and the like are not required, so that the number of parts can be significantly reduced. (2) Compared with the conventional apparatus, there is no need to weld the tubular mounting body, no tightening with a ring band, and no need to separately mount the louver to the outer wall of the vehicle body with bolts, so that the number of assembly steps is large. Reduction is possible. (3) Unlike the conventional device, there is no fear that the duct is separated due to the loosening of the ring band, and the device can always be operated in a stable state. (4) Unlike the conventional device, it is not necessary to attach the louver to the outer wall of the vehicle body with bolts, so that there is ample space and the degree of freedom in layout is increased. improves. (5) The louver legs are housed in the vehicle body, and the only part of the louver protruding outside the vehicle body is a small portion of the surface, so that interference with other objects on the vehicle body outer surface is prevented. Can be.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. In addition, about the same thing as the said 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted and demonstrates mainly a different part.

A mooring leg 42 having a mooring claw 43 at the distal end is formed at the distal end 41 of the duct 40, and a stopper 44 is formed at the base of the distal end 41 at the outer periphery of the duct 40. On the other hand, the louver 30 is a cylindrical louver leg 31.
The louver leg 31 is provided with a mooring recess 32 corresponding to the mooring claw 43. Although not shown, an alignment device is formed between the distal end portion 41 of the duct 40 and the through hole 2 so that the posture of the duct 40 with respect to the outer wall 1 of the vehicle body is always kept constant. I have.

Next, when assembling the device, the distal end 41 of the duct 40 is inserted into the through hole 2 and the mooring leg 4 is inserted.
2 is bent inward once to pass through the through hole 2,
Abuts on the inner side surface of the vehicle body outer wall 1. In this state, the louver 30 is put on the distal end portion 41 of the duct 40 from outside the vehicle body outer wall 1. That is, when the edge of the louver leg 31 is brought into contact with the mooring claw 43 and pushed in, the mooring leg 42 is similarly bent once inward, and the edge of the louver leg 31 is moved to the outer surface of the outer wall 1 of the vehicle body. At the point of contact, the mooring claw 43 of the mooring leg 42
Is fitted into the mooring recess 32, and the mooring of the duct 40 and the louver 30 is achieved, and the assembling is completed. In this state, the stopper 44 of the duct 40 and the louver leg 3
The duct 40 is attached and fixed to the vehicle body outer wall 1 in a state where the vehicle body outer wall 1 is sandwiched between the body 40 and the end edge of the vehicle body 1. Subsequent operation is the same as that of the first embodiment, and thus the description is omitted.

The present embodiment has the following effects in addition to the effects of the first embodiment. (1) Since the tip of the duct is configured to fit into the louver leg, the effective opening area of the louver can be increased in accordance with the air flow area of the inner diameter of the duct tip, thus increasing the flow resistance. And air can be efficiently introduced.

The present invention is not limited to the above embodiment, but can be implemented as follows. In the first embodiment, the louver legs are composed of the mooring legs and the guide legs.However, since the mooring legs themselves can function as the guide legs, even if the guide legs are omitted. Implementation is possible. In the first embodiment, the louver is prevented from rotating (positioning) with respect to the outer wall of the vehicle body by making the outer periphery of the louver leg partly flat. However, the present invention is not limited to this. Various deformations that exhibit a desired function, such as a projection instead, are possible. In the above embodiment, the number of mooring legs is four.

[0026]

As described above, according to the present invention, the number of parts can be greatly reduced, and the number of assembling steps can be significantly reduced. It has a remarkable effect that it becomes possible.
