Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof carrier device used for loading luggage on the roof of an automobile such as a van or a station wagon.

[0002]

2. Description of the Related Art In accordance with the recent outdoor boom, it has become common to load large loads, such as boats, on a roof carrier mounted on the roof of an automobile. Most of the conventional roof carriers are simply fixed on the roof, but a roof carrier device for manually or automatically raising and lowering the load has also appeared in order to assist in lifting and lowering the large load described above.

As a roof carrier device for manually or automatically lifting and lowering a load, there are Utility Model Registration No. 3018057 and Utility Model Registration No. 3023187. This roof carrier device has a structure in which a movable roof carrier is provided on a carrier receiving frame provided on the roof of an automobile, and both ends of a support are pivotally mounted on the end of the roof carrier and the vehicle body, respectively. Registration No. 3023187 attaches a drive device for vertically moving the roof carrier to a carrier receiving frame or a roof carrier. In each case, the roof carrier loaded with the load descends along a predetermined trajectory by the restraint of the support provided along the rear hatch.

[0004]

[Problems to be Solved by the Invention] The above-mentioned utility model registration No. 30
In the roof carrier device of No. 18057 and Utility Model Registration No. 3023187, when the roof carrier is moved on the roof,
There is a problem that the strut is stuck to the rear hatch and the rear hatch cannot be freely opened and closed. In addition, in order to separately attach a support that is not originally provided on the rear hatch, it is necessary to separately create mounting members for this support for each vehicle type. And the need to modify the vehicle body side that supports the pillars, resulting in increased costs.

Another problem is the power required to return the roof carrier lowered on the roof to the roof. In Utility Model Registration No. 3018057 and Utility Model Registration No. 3023187, the lowered roof carrier connects the lower end of the rotating shaft of the carrier receiving frame to the end of the support, and the roof carrier is restrained on the track by the support. It moves forward while rotating and returns to the roof. At this time, since the center of gravity of the roof carrier is far away from the center of rotation at first, the roof carrier moving upward on the roof is always subjected to a moment of downward rotation. Unexpectedly large force, mechanical driving force, etc. are required to push up the roof carrier.

As described above, Utility Model Registration No. 3018057,
Utility model registration No. 3023187 points out the structural problems resulting from the device configuration, the problem that increasing the number of applied vehicles results in high costs, and the problem that large power is required when moving the roof carrier. Can be. Therefore, in order to solve the above problems, a new roof carrier device was to be developed.

[0007]

What has been developed in this manner is a roof carrier device having a carrier receiving frame fixed to a roof of an automobile, having a rotating shaft and a roof carrier movably provided on the carrier receiving frame. The load is loaded on the roof carrier that has been rotated and tilted about the rotation axis, and has been lowered in this tilt direction, and the roof has a height such that the center of gravity of the roof carrier with the loaded load substantially coincides with the rotation axis. A roof carrier device characterized in that a drive device for lifting the carrier in an inclined direction is mounted between the carrier receiving frame and the roof carrier. The driving device is a cylinder consisting of a piston part and a base part, which is mounted between the carrier receiving frame and the roof carrier such that the base part is supported by the carrier receiving frame and the front edge of the roof carrier can be pushed out by the extended piston part. Then, by extending the cylinder, the roof carrier may be lifted in the inclined direction to a height at which the center of gravity of the roof carrier with the load loaded thereon substantially coincides with the rotation axis.

According to the roof carrier device of the present invention, after the roof carrier, which is horizontal when the load is loaded, is moved rearward along the carrier receiving frame, the load can be attached and detached by rotating about the rotation axis. An inclined state, for example, a substantially vertical state. The roof carrier on which the load is mounted in a substantially vertical state is lifted upward by a driving device so that the center of gravity of the roof carrier in a state where the load is loaded is substantially aligned with the rotation axis, and the weight is balanced around the rotation axis. Plan. The roof carrier thus weight-balanced can be sufficiently rotated by a small force, for example, even by a human hand, and there is no possibility that the roof carrier will be rapidly rotated even if the hand is released. The roof carrier returned to horizontal,
Further, it is moved forward by a human hand and completely moved onto the carrier receiving frame, and is fixed to the carrier receiving frame by, for example, hooking or inserting a pin, and the operation is completed.

In the above-described roof carrier device, a large force is required to lift the lowered roof carrier until the center of gravity substantially coincides with the rotation axis. The driving device is a power for lifting the roof carrier loaded with the load, and a cylinder including a piston portion and a base portion is optimal. The drive device may be a combination of a pulley for amplifying human power, in addition to a motor and a spring. When the cylinder is mounted between the carrier receiving frame and the roof carrier so that the front edge of the roof carrier can be pushed out by an extended piston portion, the cylinder is supported by a carrier receiving frame, preferably a rotating shaft. It fits inside the roof carrier frame and rotates with the roof carrier, so it does not get in the way. It should be noted that the piston part and the roof carrier are not irremovably connected, and the lifted roof carrier is turned to be horizontal, and then the roof carrier alone is moved forward away from the piston part.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an automobile 2 on which a roof carrier device 1 of the present invention is mounted, as viewed from the rear. In the roof carrier device 1 of the present invention, when the luggage is loaded, the entire device is on the roof 7 of the vehicle 2, and the vehicle 2 is mounted on the vehicle 2 using only a ready-made carrier bar (not shown) without providing a support on the rear hatch 8. The advantage is that the type of vehicle to be mounted is not limited. As shown in FIG. 1, a rotating shaft 6 is provided at the rear edge of the carrier receiving frame 9 fixed on the roof 7 of the vehicle. The shaft rollers 10 provided at both ends of the rotating shaft 6 are provided.
And the roof carrier 4 is attached.

The roof carrier 4 can be moved back and forth on a straight line including the rotation shaft 6 along the carrier receiving frame 9 by the function of the shaft roller 10, and furthermore, can be rotated about the rotation shaft 6 as an axis. 3, 5, 10, and 12 are compared). Also,
A base 11 of the air cylinder 5 is mounted on the rotation shaft 6, and a tip of the piston 12 is connected to a bridge bar 14 in which bar rollers 13 provided at both ends are fitted into the roof carrier 4. The bar roller 13 can be pressed against the front edge of the roof carrier 4 as it extends. In addition, the bar roller 13 with respect to the
Of the roof carrier 4 by extending the air cylinder 5 can be adjusted, and when the roof carrier 4 is lifted, the center of gravity G of the roof carrier 4 loaded with the load is pivoted as much as possible. 6 (compare FIGS. 6, 7 and 8).

The operation of the roof carrier device 1 of the present embodiment will be described along the procedure for loading the boat 3. FIG. 2 is a side view showing a state in which the boat 3 is fixed to the lowered roof carrier 4, and FIG. 3 is a side view showing only the carrier receiving frame 9 and the roof carrier 4 in the same state. As shown in FIG. 2, the roof carrier 4 pulls the operating rod 15 to lower the auxiliary roller 18 rearward along the carrier receiving frame 9 while rolling on the rail 17 (see FIG. 3). Is rotated downward about the axis and is in a substantially vertical state. The rail 17 regulates the trajectory of the front and rear movement of the roof carrier 4. At this time, if the operating rod 15 is grounded, the roof carrier 4 is stabilized, and the loading and unloading of luggage including the boat 3 becomes easy. The boat 3 is placed upward, for example, at a position where the rear end is close to the operating rod 15, and is pushed up with the grounded lower edge as an axis to bring the upper surface of the boat 3 into contact with the roof carrier 4, and a rope (not shown). )). In the roof carrier device 1 of this embodiment, a damper 16 supported by the carrier receiving frame 9 is connected to the base 11 of the air cylinder 5 in order to make the rotation of the roof carrier 4 gentle.

FIG. 4 is a side view showing a state where the roof carrier 4 is lifted by extending the air cylinder 5, and FIG. 5 is a side view showing only the carrier receiving frame 9 and the roof carrier 4 in the same state. As can be seen in FIG.
Air, water and other pressurized medium
By feeding and elongating (for example, exhaust gas), the roof carrier 4 to which the boat 3 is fixed is pushed up in a substantially vertical direction while maintaining the attitude in the substantially vertical state. The air cylinder 5 closes the valve in this extended state and keeps the air cylinder 5 filled with the pressurized medium.

The center of gravity G of the roof carrier 4 to which the boat 3 is fixed is initially lower than the rotation shaft 6 (see FIG. 2).
However, due to the extension of the air cylinder 5, the center of gravity G is raised to a position substantially coincident with the rotation shaft 6, and the roof carrier 4 achieves weight balance about the rotation shaft 6. Since the position of the center of gravity G changes depending on the type of the load and the state of loading, in this example, FIGS. 6 to 8 (FIG. 6 is a view taken in the direction of arrow A in FIG. 5, FIG. FIG. 8 shows the case where the bar roller 13 is displaced rearward and is attached to the erection bar 14 when attached to the bar 14, respectively.
As can be seen from FIG. 5, by changing the mounting position of the bar roller 13 with respect to the erection bar 14, the rising position of the center of gravity G (see FIG. 4) of the roof carrier 4 due to the extension of the air cylinder 5 can be adjusted.

FIG. 9 is a side view showing a state in which the roof carrier 4 is turned about the rotation shaft 6 to be horizontal, and FIG. 10 is a side view showing only the carrier receiving frame 9 and the roof carrier 4 in the same state. FIG. 11 is a side view showing a state where the roof carrier 4 has been moved forward to complete loading, and FIG. 12 is a side view showing only the carrier receiving frame 9 and the roof carrier 4 in the same state. The roof carrier 4 thus returned to the horizontal state is further pushed forward by hand while holding the operating rod 15, thereby changing the state of FIG. 9 to the state of FIG. 11 and completing the loading on the roof 7 of the automobile. In the air cylinder 5, the piston 12 has an erecting bar 14, a bar roller
13, the roof carrier 4 is only engaged with the roof carrier 4, so that the extended air cylinder 5
Can be moved away from the front. In this example, in order to stabilize the posture when the vehicle 2 is running, in this example, the pin 19 of the roof carrier 4 is hooked on a hook 20 provided on the carrier receiving frame 9 so that the roof carrier 4 does not float from the carrier receiving frame 9. However, in order to prevent horizontal movement of the roof carrier 4 due to vibration, it is preferable to perform pinning or the like.

The operation of unloading the boat 3 is substantially the reverse of the loading procedure described above. At this time, the front edge of the roof carrier 4 moved rearward from the state of FIG. 12 comes into contact with the bar roller 13 again (see FIG. 6), and when the roof carrier 4 is lowered from the state of FIG. 5
By opening the valve and gradually discharging the pressurized medium pressurized and held in the air cylinder 5, the roof carrier 4 supported by the air cylinder 5 can be gently lowered. That is, the air cylinder 5 functions as a damper to prevent the roof carrier 4 from suddenly lowering. In addition,
When exhaust gas is used as the pressurized medium, there is an advantage that it is not necessary to separately load a pressurized medium on the vehicle,
Since a long time has passed since the last delivery to the air cylinder, it may have leaked out slightly. It is good to show the function.

[0017]

According to the roof carrier device of the present invention, a large load such as a boat can be loaded on a roof without damaging large loads such as boats and without requiring labor (number of people or power). In addition, since the entire device can be mounted on the roof, it does not hinder the opening and closing of the rear hatch. Since it can be installed at a height, there is an advantage that the versatility is extremely high.

When the cylinder is used as a driving device, the structure of the roof carrier device is simplified. In particular, when unloading a load, the cylinder functions as a damper when the roof carrier is lowered to a substantially vertical state.
Safety can be improved. In particular, when the cylinder is an air cylinder, the exhaust gas of an automobile can be used, so that there is no need to provide a separate power source and the cost can be reduced.
