BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to screen protective devices and more particularly to a detachable screen guard assembly for protecting a screen and mounted on a screen frame of an image display device.
2. Description of the Related Art
A great majority of the increasingly popular flat-screen monitors and flat-screen televisions have substantially fragile screens that need to be protected from accidental damage. In addition to the propensity of the screen being damaged, a screen protective device may benefit a viewer by reducing glare and radiation emitted by the screen.
A conventional screen protective device on the market is a hanging-type screen protective glass or plastic that in some cases is strapped to a monitor. This type of device, when hanging on top of a frame of a monitor, produces an inharmonious appearance to the monitor. Moreover, the hanging-type screen protective device utilizing two straps each connected to the top and the bottom of the screen protective device. These type devices have high manufacturing cost that makes it unaffordable for many users.
There are a number of previously developed screen protective devices that do not solve all challenges posed by the broad use of such devices with an existing monitor. Since a screen protective device is generally targeted for use by a broad consumer base, the installation process should be easy to perform even by an unskilled individual. In addition, the screen protective device should be easily detachable for cleaning. Further, the screen protective device should fit a wide range of presently manufactured monitors and should have low manufacturing cost.
Another screen protective device on the market is a thin protective membrane made of acrylic that directly attaches to a screen of a monitor. This type of protective device provides limited protection since it cannot prevent damage in case of substantial impact. In addition, it is hard to install on large size screens.
To overcome the shortcomings, the present invention provides detachable screen guard assembly to mitigate and obviate the above mentioned drawbacks.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a detachable screen guard assembly for protecting the screen of an existing monitor. The drawbacks in the prior art and the conventional screen protective devices are overcome by the present invention as described below.
To achieve the objective, a detachable screen guard assembly mounted on a screen frame of a monitor comprising a screen protector and a fastening apparatus. The screen protector is transparent and made of glass, acrylic, or plastic having excellent transparency.
The fastening apparatus includes at least one couple of a hooking member and a bracket member. The bracket member is mounted on the screen frame and the hooking member is mounted on the screen protector. The hooking member attaches mechanically to the bracket member. Because the hooking member can be disengaged from the bracket member, the screen protector can be detached from the screen frame to be cleaned or mounted on another monitor that has a bracket member installed.
The present invention can be manufactured cost efficiently and can easily be installed on a monitor by an unskilled individual. The detachable screen guard assembly conveniently attaches to a monitor completely protects the screen and keeps the monitor neat in appearance. Once installed, the fastening apparatus allows the screen protector to be detached from and position-adjusted with respect to the monitor. In addition, once installed on the monitor, the detachable screen guard assembly can easily be entirely removed without leaving marks or damaging the monitor.
In addition, the current invention includes a securing device that utilizes a new and innovative method for securing a screen protector on an image display device. The method involves strapping the screen protector to the monitor support. This is a significantly more cost efficient method compared to any known methods for securing a screen protector to a monitor using straps. Further, this method allows for fewer connection points between the securing device and the screen protector compared to traditionally available securing devices. Provided that most connection points are exposed, reducing their number significantly improves the viewing experience of the viewer.
The securing device offers tremendous versatility and is significant improvement over the prior art securing the screen protector to a monitor in a completely new way that was never thought or suggested in the past.

Preferably, the screen protector (10) further has anti-glare and anti-radiation efficiencies to reduce a potentially harmful radiation and make users feel comfortable when they use the monitor (12). It is to be understood that other materials may be used in so far as they provide easy viewing of the screen (17).
The screen protector (10) is mounted detachably in front of the monitor (12) and is constructed preferably in generally a rectangular shape. However, it is to be understood that such shape may be sized according to the shape and size of the monitor (12) on which it is to fit.
Additionally, the size of the screen protector (10) is ideally diminished to not cover parts of the monitor (12), and controlling buttons (18) when present on the front surface of the screen frame (13). Therefore, appearance of the monitor (12) is kept original and the controlling buttons (18) are operated as usual without obstruction. Moreover, the screen protector (10) with the fastening apparatus (11) has a simple structure so that the manufacturing cost of the detachable screen guard assembly is decreased.
Further, in a preferred embodiment, the screen protector (10) has finished edges and rounded corners for improved appearance and to prevent injuries by accidental scraping or cutting of the user when working around the monitor. However, it is to be understood that such rounding of the corners of the screen protector (10) is for ergonomic reasons and that the corners may be shaped differently depending on various factors. In another embodiment (not shown), the screen protector (10) has a frame that improves appearance, holds the screen protector (10), or connects to the fastening apparatus (11).
The fastening apparatus (11) is mounted on the screen frame (13), detachably fastens the screen protector (10) in front of the monitor (12), and has one or multiple couples of a bracket member (15) and a corresponding detachable hooking member (14). With reference to FIG. 1, in the preferred embodiment, the fastening apparatus (11) comprises of four couples of the bracket member (15) and the hooking member (14). Moreover, the bracket member (15) and the hooking member (14) may be in different shapes and sizes, and may have different positioning on the screen frame (13) and the screen protector (10) respectively.
With reference to FIGS. 2, 3 and 4, the bracket member (15) is mounted on the surface of the screen frame (13) and has a front surface and a rear surface. The rear surface of the bracket member (15) connects to and is mounted on the surface of the screen frame (13) by removable adhesive tape. In addition, the bracket member (15) can be constructed such that it snaps on/off to the screen frame (13) or such that it is mounted on the surface of the screen frame (13) by glue or an adhesive tape. In the preferred embodiment, the bracket member (15) attaches to the screen frame (13) by adhesive attachment strips that can be easy to remove without leaving marks. The attachment strips may utilize removable or semi-permanent adhesive that can be removed without leaving marks or causing damage on the screen frame (13).
The hooking member (14) is mounted on the surface of the screen protector (10) and has a front surface and a rear surface. The rear surface of the hooking member (14) connects to and is mounted on the surface of the screen protector (10) by glue or an adhesive tape.
