BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fan roof opening / closing device capable of automatically performing opening / closing operations of a fan roof of a truck by using a drive source such as a reversible motor.

[0002]

2. Description of the Related Art A truck bed may be entirely covered with a box-shaped body in order to protect cargo during transportation. This body hinders work when loading and unloading cargo. Often.

Therefore, it is usual to form a body by combining a cantilever roof having an L-shaped cross section for opening and closing the loading platform up and down and a cantilever plate for opening and closing the lower part of the cantilever roof. At this time, the roof can be opened and closed up and down via a hinge with respect to the central beam that is installed in the center of the upper part of the loading platform in the front-rear direction. Together with it form the sides of the body. In addition, in order to easily open and close the roof from the ground, it is common to have a manual opening and closing mechanism using wires, ropes, etc. (for example, Japanese Utility Model Publication 56).
-4543).

[0004]

According to the prior art, since the fan roof is opened and closed through wires and ropes, the opening and closing operation is difficult and troublesome, and the tip of the wires and ropes is different for each operation. Since the parts have to be cleaned up, the problem that opening and closing operations take time is inevitable.

Therefore, in view of the problems of the prior art, an object of the present invention is to use a drive source such as a reversible motor so that the opening / closing operation can be performed very easily and can be performed in a short time. To provide a switchgear.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the structure of the present invention is a slanted roof which is attached to a central beam installed in the center of the upper part of the loading platform in the front-rear direction so that it can be opened and closed vertically via a hinge. The gist of the invention is to provide a link for connecting the fan roof and the upper part of the luggage carrier panel, and a link that pushes up the fan roof and a reversible motor that drives the link up and down via a worm mechanism.

It should be noted that instead of the reversible motor, a cylinder for driving the link up and down can be used.

Further, the pinion may be fixed to the hinge shaft of the roof and the pinion may be driven by a reversible motor. Further, the rack is connected to the roof and the pinion meshing with the rack may be driven by the reversible motor. You may.

[0009]

According to the structure of the present invention, the link connects the fan roof and the upper part of the luggage carrier panel, and the reversible motor drives the link up and down. If operated in reverse, the link roof can be opened or closed by pushing the link up or down.

The same is true even if the reversible motor is replaced with a cylinder.

If the pinion is fixed to the hinge shaft of the roof, the pinion is rotated in the forward and reverse directions,
The fan roof can be opened and closed, and if the rack is connected to the fan roof, the reversible motor can drive the rack through the pinion and likewise open and close the fan roof.

A central beam 24 having hinges 24a, 24a on both the left and right sides is provided between the storage members 21a, 21a at the center of the upper portion of the luggage carrier L in the front-back direction of the luggage carrier L. However, in FIG. 1, only the front side of the luggage carrier panels 21 and 21 and the storage members 21a and 21a is shown.
Further, the baffle plates 23, 23, the hinges 24a, 24a ...
Only the right side of the bed L and the central beam 24 are shown respectively.

The folding roof 22 is a plate material 2 bent into an L shape.
2a and a reinforcing material 22b for edging the peripheral edge of the plate material 22a
And a part of the reinforcing member 22b serves as a hinge shaft that penetrates the hinges 24a, 24a on one side of the central beam 24, and is attached to the central beam 24 so as to be vertically openable and closable as a whole. .. In addition, the hinge shaft,
If necessary, a torsion spring for urging the fan roof 22 in the opening direction may be provided.

The baffle plate 23 is swingably supported via hinges 23a, 23a ... Attached to the side ends of the luggage carrier L.

Raised roofs 22 and 22 and rails 23 and 23
Means that, in the closed state, the front and rear cargo bed panels 21, 2
1, a box-shaped body can be formed above the luggage carrier L to completely close the upper portion and the left and right side surfaces of the luggage carrier L. In the open state, both sides of the luggage carrier L can be largely opened. ..

It is assumed that the opening / closing devices are symmetrically assembled on the left and right sides of the front loading platform panel 21 corresponding to the respective roofs 22.

The reversible motor 11 is provided with a speed reducer 11a and is fixed to the upper front part of the luggage carrier panel 21 via a bracket 11b (FIGS. 1 and 2).

The worm mechanism 12 comprises a worm 12a and a worm wheel 12b, and the worm 12a is connected to the reversible motor 11 via a speed reducer 11a.
The shaft 12c of the worm wheel 12b has a storage member 21a.
It is rotatably supported by a bearing bracket 12d that is fixed inside, and penetrates the housing member 21a to the front side.

The link 13 includes a pair of swing levers 13a and 13a protruding from the shaft 12c and swing levers 13a and 13a.
It is composed of a connecting lever 13b for connecting the a and the roof 22 with each other. The connecting lever 13b and the fan roof 22 are connected via a bracket 13c.

The intermediate portions of the swing levers 13a, 13a are connected to the storage member 21a via a spring member 13d (FIG. 1).

The spring member 13d comprises a spring (not shown) inside a suitable outer cylinder, and the swing lever 13a,
An adjustable tensile force shall be exerted on 13a.
That is, the spring member 13d corresponds to the link 1 in FIG.
3 is urged in the direction of arrow K1. The spring member 13d is
It is swingably attached to the bottom surface of the storage member 21a via the bracket 13e.

Between the rear part of each fan roof 22 and the rear storage member 21a (not shown), the same links 13, spring members 13d as those mounted on the front part of the fan roof 22 and also the fan roof 22 are provided. A stopper chain that regulates the opening angle is installed.

Now, consider a case where one of the tilted roofs 22 is opened from the closed position (FIG. 3) to the open position (FIG. 4).

When the reversible motor 11 is started via an operation switch (not shown) and the worm wheel 12b is driven in the direction of arrow K2 in FIG. 3, the swing lever 13 of the link 13 is moved.
The a and 13a swing upward about the shaft 12c (in the direction of arrow K3 in the figure). Therefore, the connecting lever 13b can push the fan roof 22 upward, and the fan roof 22 can be pushed up.

At this time, the front and rear spring members 13d, 13d
Urges the swing levers 13a, 13a, ... upwardly, that is, in the direction to open the fan roof 22, so that the fan roof 22 can be opened by an extremely light motion, and the reversible motor can be opened. A small capacity 11 is sufficient. However, the front and rear spring members 13d and 13d are used when the weight of the fan roof 22 is light, or when a torsion spring attached to the hinge shaft of the fan roof 22 sufficiently urges the fan roof 22 in the opening direction. This can be omitted. Further, since the spring member 13d generates an assisting force when the cantilever roof 22 is opened, this spring member 13d is provided with any optional member such as a gas damper as long as it can achieve the same function. It may be replaced with a biasing member. Further, the spring members 13d and 13d may be provided only on the rear side of the luggage carrier L where the driving force of the reversible motor 11 cannot be obtained.

On the other hand, when closing the fan roof 22,
The worm wheel 12b is rotated in the reverse direction via the reversible motor 11 (direction of arrow K5 in FIG. 4). As a result, in the link 13, the swing levers 13a, 13a swing downward (in the direction of arrow K6 in the figure), so that the fan roof 22 can be closed in the direction of arrow K7 in the figure. In addition, when the fan roof 22 is closed, the front and rear links 13, 13 and the spring members 13d, 13d are arranged in the front and rear storage members 21a, 21a.
It can be compactly housed inside (Fig. 3).

When the fan roof 22 is opened and closed as described above, the spring member 13d is provided with an appropriate offset plate 13
By connecting the rocking levers 13a, 13a via a1, a large rotational moment can be applied to the link 13 at the start of the opening operation of the canopy roof 22.

On the other hand, the relative angle θ between the connecting lever 13b and the cantilevered roof 22 when the cantilevered roof 22 is closed is
Generally, it is preferable to set it in the range of 15 ≦ θ ≦ 50 (degrees). When the canopy roof 22 is opened, the component force Px effective to open the canopy roof 22 against the push-up force P to be applied to the connecting lever 13b is Px = Psin θ, so if the relative angle θ is small, The required pushing force P becomes excessively large, and the required torque of the reversible motor 11 becomes excessively large. Also,
If the relative angle θ is too large, the required depth of the storage member 21a becomes large and the overall compactness is impaired. 30 ≦ θ ≦
About 45 (degrees) is particularly suitable.

Such an opening / closing device is provided in the front loading platform panel 2
Instead of arranging it in No. 1, it may be arranged in the cargo bed panel 21 later. However, the link 1 is attached to the rear loading panel 21.
3. Since the spring member 13d has already been mounted, the rear opening / closing device only needs to additionally mount a lacking member including the reversible motor 11. In addition, since the spring member 13d is merely an auxiliary member, the opening / closing device is attached to the front and rear cargo bed panels 2.
It may be deleted regardless of whether it is attached to No. 1 or 21.
