AUTOMOBILE PICKUP BED ROOF

FIELD OF THE INVENTION

Engineering related to an automobile pickup bed roof

BACKGROUND OF THE INVENTION

Recently pick-up truck type automobiles are widely used, both in transporting goods and as personal automobiles, which carry personal belongings in the pickup bed. However, due to weather and dust on the roads which can damage goods and personal belongings contained in the pickup bed, there is an introduction of a roof to be installed on the automobile’s pickup bed. Typically, the automobile pickup bed roof installed to the automobile pick up bed is provided with a roof fixing unit, enabling the automobile pickup bed roof to be attached to the automobile pick up bed. Furthermore, the automobile pickup bed roof has a passenger entrance, an air ventilation, and water drainage, making the automobile pickup bed roof preferential.

Conventionally, in order to install the roof to a automobile pick up bed securely by a conventional roof fixing unit, one has to fasten a clamping arm to an upper edge fixing panel. Thus, installing of the conventional pickup bed fixing unit has to be done in piece-by-piece manner, and it is difficult to tighten and align these pieces into their proper positions.

A conventional hinge is composed of two panels connected to each other and has a connecting part as a pivoting point. The connection of the hinge with two panels connected together makes it difficult to dissemble, or even impossible to separate them apart. This makes it difficult to install or replace a window and a door panel when needed.

A conventional open -close device is used for installing a window to an automobile. The window is a sliding panel type which can be slid in order to open/close the window. However, when the automobile is travelling in a high speed, a resulted wind pushes the window to close. Furthermore, at the front window panel, vibration from the automobile’s engine can make the window slide by itself. Also, in another conventional open-close device which comprise a shock absorber bar for pushing/pulling a window panel open or close, respectively. However, after being used for a period of times, the shock absorber bar will deteriorate and loss it strength so that it cannot keep the window panel open. In another conventional window open/close device, a window hinge with a spring loaded is used for open-close the window. When the loaded spring deteriorates due to fatigue, it will be difficult to push the window panel up.

A conventional waterproof rubber seal is a device for preventing water from penetrating into the pickup bed. This device receives water from a water drainage and trough around the rear door panel and discharge the water out of the pickup bed. However, said convention device cannot function properly when being used in some conditions, such as under heavy raining or under high pressure water during car washing, in which water can penetrate through connecting points of the edge backing rubbers if the attachment of the edge backing rubbers are not good enough.

SUMMARY OF THE INVENTION

A roof of an automobile pick up bed has a roof fixing unit which attaches the pickup bed to the automobile pick up bed and the automobile pick up bed has a hinge fixing unit for attaching the window panel or the door panel to the roof of the automobile pickup bed in order to be the entrance passage. The roof has an open-close device which locks the front window panel in a holding-up position for air ventilation. Also, the rear part of the roof of the automobile pickup bed is provided with a water drainage device to discharge water out of a groove of the rear door panel.

An objective of the present invention is to provide a device for installing the roof of an automobile pickup bed with safety and maximum utilization.
