1. Field of the Invention
The present invention relates to a displayer mounting device, and more particularly to a displayer mounting device for attaching or mounting video monitors or video players or displayers to passenger vehicles without occupying spaces of the passenger vehicles.
2. Description of the Prior Art
Typical displayers or video monitors or video players are normally received in a principle case which is then attached or mounted onto the seat backs or the headrests of the passenger vehicles, for allowing the users or the passengers of the vehicles to view or to play TV, VCR, CRT, VCD, DVD within the passenger vehicles.
For example, U.S. Pat. No. 6,092,705 to Meritt discloses one of the self-contained cases for housing, transporting and mounting video monitor and video player for use in passenger vehicles, and comprises one or more mounting straps attached onto the self-contained cases for attaching or mounting the video monitor and video player to the seat backs and the headrests of the passenger vehicles.
However, the self-contained cases may occupy a large space of the passenger vehicles, particularly the tiny space between the seat backs and the rear cabin or seats for passengers of the passenger vehicles, such that the passengers may not feel comfortable within the tiny rear cabin of the passenger vehicles.
U.S. Pat. No. 6,216,927 to Meritt discloses an entertainment accessory for releasably mounting or securing in passenger vehicles, and also comprises one or more mounting straps attached onto a self-contained case for attaching or mounting the entertainment accessory to the headrests of the passenger vehicles.
