The present invention relates to a modular audio-visual device, and particularly to a modular audio-visual device of which component elements can be assembled into a module for diversified use or kept alone for simple use in various traffic means.
It is an important part for modern life to go to work, come off duty, travel, or travel on official business by traffic means. On an average each person spends about two hours in traffic means each day, and the greater part of traveling inside or outside the country is spent in traffic process. Most people may read books, newspapers and magazines, listen to music or watch videotapes in the time of traffic process.
Reading books, newspapers or magazines in traffic means can easily make readers uncomfortable; the people therefore prefer audio listening or video watching. Moreover, the development in audio and video products and the competition in traffic means market promote the tendency of audio listening and video watching in traffic means.
In this situation, some businessmen in this field put forward an elongated audio-visual device with a leading end and a trailing end, as disclosed in U.S. Pat. No. 5,775,762. This prior art provided with a screen at front end and a disc player at the rear end for watching and providing audio-visual data. The user can freely select and display the audio-visual content he likes by controlling the control elements of screen and audio-visual device.
However, because the space in the traffic means like cars is limited and the elongated audio-visual device with front and rear end occupied rather large space, the movement and the vision field of the passengers are largely limited. Moreover, the audio-visual device has become a standard equipment of cars due to the competition in car market today, so this kind of audio-visual device is indeed a waste in resources.
Additionally, some businessmen put forward a display device with only screen for cars, as disclosed in the U.S. Pat. No. 5,946,055. This kind of screen has a frame joined to the car roof and is installed near the center or the rear seats of the car. The screen can turns around a rotational axis connected with the frame of the screen and can be stored in the frame. The display side of the screen faces to lower direction of the frame when the screen is stored and the display side faces to the passengers when the screen is turned round.
The kind of display device can be used for car, which has been provided with an audio-visual device and can avoid the waste in resources. However, if a car has not been provided with an audio-visual device, it cannot be provided with only a display device to enjoy the audio-visual display.
Therefore, a need exists for a modular device, which can be assembled from component elements and can improve the prior device. The present invention provides such a device.
The main object of the present invention is to provide a modular audio-visual device for various traffic means. The users can freely choose and buy component elements to assemble a device with only display function, only audio-visual function, or both display and audio-visual functions. The present invention has the advantages of diversified selection in use and convenience for assembling.
To achieve the said object, the present invention includes a first and a second supporting elements, an audio-visual device sustaining element, a display sustaining element and a plurality of sets of fixing elements. The assembling way of the modular audio-visual display device depends on the demand of the user, and can be provided with three types: only display function, only audio-visual function, and both display and audio-visual function.
When a device with both display and audio-visual functions is selected by user, its component elements are: the first supporting element with a first surface, a second surface and a plurality of open grooves, wherein the first surface is connected to the traffic means, and a plurality of locating tubes is extended downward from the second surface, the plurality of open grooves across through the first and the second surface; the audio-visual device sustaining element with a first surface, a second surface, a space for receiving the audio-visual device and a plurality of thorough holes corresponding to the plurality of locating tubes, wherein the plurality of through holes across through the first and the second surface and are penetrated by the plurality of locating tubes of the first supporting element, the space is under the second surface for receiving the audio-visual device, the first surface is connected with the second surface of the first supporting element; the display device sustaining element with a first surface, a second surface, a space for receiving the audio-visual device, and a plurality of through holes corresponding to the plurality of through holes of the audio-visual device sustaining element, wherein the plurality of through holes across through the first and the second surface, the space is under the second surface for receiving the display device, the first surface is connected with the plurality of locating tubes of the first supporting element; and a plurality of sets of fixing elements with a first set of fixing elements and a second set of fixing elements, wherein the first set of fixing elements penetrate the plurality of open grooves of the first supporting element and joined to the traffic means, the second set of fixing elements penetrate the plurality of through holes of the display device sustaining element and are joined with the plurality of locating tubes.
When a device with only audio-visual function is selected by user, its component elements are: the first supporting element with a first surface, a second surface, and a plurality of open grooves, wherein the first surface is connected with the traffic means, the plurality of open grooves across through the first and the second surface, and a plurality of locating tubes is extended out from the second surface; the audio-visual device sustaining element with a first surface, a second surface, a space for receiving the audio-visual device, and a plurality of through holes corresponding to the plurality of locating tubes, wherein the plurality of through holes across through the first and the second surface and are penetrated by the plurality of locating tubes, the space is under the second surface for receiving the audio-visual device, and the first surface is connected with the second surface of the first supporting element; and the plurality of sets of fixing elements with a first set of fixing elements and a second set of fixing elements, wherein the first set of fixing elements penetrate the plurality of open grooves of the first supporting element and are connected to the traffic means, the second set of fixing elements connected with the plurality of locating tubes of the first supporting element. The space of the audio-visual device sustaining element is further provided with a U-shape frame for sustaining the audio-visual device, wherein the two sides of the frame is extended upward and bended to form a connecting portion, the connecting portion is provided with a plurality of through holes and is joined with the second surface by screws penetrated the plurality of through holes.
When the user choose a device with only display function, the modular display device comprises: the second supporting element for fixing the device to the traffic means is provided with a first surface, a second surface, a plurality of open grooves and a plurality of connecting holes, wherein the first surface is connected with the traffic means and the plurality of open grooves and the plurality of connecting holes across through the first and the second surface; the display device sustaining element is provided with a first surface, a second surface, a space and a plurality of through holes corresponding to the plurality of open grooves, wherein the first surface is connected with the second surface of the second supporting element, the space is under the second surface for receiving a display device, and the through holes across through the first and the second surface; the plurality of sets of fixing elements are provided with a first set of fixing elements and a second set of fixing elements, wherein the first set of fixing elements are joined to the traffic means through the plurality of open grooves of the second supporting elements and the second set of fixing elements are joined with the plurality of the connecting holes of the second supporting elements through the through holes of the display device sustaining element.
