Benefits of technology

[0013]One advantage of the present invention is to provide a fastening assembly for receiving a portable projector fixed therein.
[0014]Another advantage of the present invention is to provide a fastening assembly that can be coupled with other conventional portable supporting assemblies (e.g. tripods) or functional modules (e.g. camera pan-tilts) so as to allow a portable projector settled therein to be adjusted for desired projection directions and angles in a space where a supporting assembly and a hanging bracket are not available.

Problems solved by technology

However, since the conventional CRT requires an electronic gun, which has a significant volume, to excite fluorescent materials, the early projector is consequently bulky and merely adaptive to be used in commodious space where a fixed site for installing such projector is provided, such as a conference hall or a cinema.
Consequently, the traditional bulky CRT projectors tend to be replaced by the LCD projectors gradually.
DLP technology can not only refine the projected images, but also efficiently reduce the volume and weight of a projector to make it light, slim, and small.
As mentioned previously, while the traditional projectors are bulky and unfavorable for portability, the same are typically settled on tables or mounted on hanging brackets to perform projection.

Embodiment Construction

[0025]Please refer to FIG. 1 for a schematic drawing showing a portable projector and a fastening assembly thereof according to one embodiment of the present invention. Therein, the fastening assembly 2 for the portable projector is substantially a housing with a chamber 3 formed therein. The chamber 3 is such configured that dimensions thereof can fittingly receive the portable projector 1. An opening 4 is formed at a front end of the fastening assembly 2 and such configured that dimensions thereof can just allow the portable projector 1 to enter the chamber 3 therethrough, as indicated by the white arrow in the drawing. After entering the chamber 3, a lens 10 of the portable projector 1 is exposed. A tenon 5 is provided at an inner bottom surface of the chamber 3 adjacent to the opening 4. Thereby, when the portable projector 1 is completely loaded in the chamber 3, the tenon 5 can be engaged with a recess (not shown) formed at a bottom of the portable projector 1 so as to retain ...

Abstract

A projector, a fastening assembly thereof and a fastening method are provided. The fastening assembly can accommodate the portable projector and fasten it onto a tripod or a pan-tilt to perform projection. The fastening assembly has specific open regions that allow a user to access function keys of the projector and allow I / O ports of the projector to be connected with external devices.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The present invention relates to a projector, a fastening assembly thereof and a fastening method thereof. More particularly, the present invention relates to a portable projector and its fastening assembly as well as its fastening method.[0003]2. Description of Related Art[0004]Over the past ten-odd years, may significant improvements related to image projecting apparatuses have been made by virtue of the progress of semiconductor process and the development in the latest technologies. Especially, the breakthrough is presented in the dimensions, image quality and image signal processing thereof. The image projectors implementing three-beam CRT scanning technology were produced early on and had advantages of high definition, excellent color saturation and high contrast originated from CRT imaging technology. However, since the conventional CRT requires an electronic gun, which has a significant volume, to excite fluorescent ma...
