1. Field of the Invention
This invention relates generally to a portable mobile device accessory which functions as a mouse pad, a screen cleaning cloth, a writs rest for a keyboard, a stand and a protector for a mobile device.
2. Description of Related Art
Conventional mouse pads are too big and thick to carry with a mobile device such as a smartphone, a laptop computer or a tablet PC. Previously, some have proposed a pull out mouse pad built into a laptop. U.S. Pat. No. 7,922,141 teaches a mouse pad apparatus that removably attaches to a laptop computer via spaced apart flex clips affixed to one side of the platform border. However, the conventional mouse pads need additional apparatus to carry mouse pads. Most microfiber glasses or screen cleaners are also hard to be carried on the laptop or tablet PC because they are just plain cloths. Users need to carry them on the cases separately. The conventional gel wrist mouse pads on the market are too thick to be attached or carried on the laptop computer. Thus, mobile device accessories that can be easily carried and removably attach to a surface such as a surface of a laptop computer or a tablet PC are needed.

DETAILED DESCRIPTION

The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of embodiments of this invention are presented herein for purposes of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
According to an embodiment of the present invention, a portable mobile device accessory 10 includes a first layer 11 having a polymer adhesive layer 12 as shown in FIGS. 1 and 2.
The material for the first layer 11 may be varied according to the purposes of the portable mobile device accessory. For example, if the portable mobile device accessory 10 is intended to be used for screen-cleaning, a first layer 11 may be formed of a material which can be used for screen-cleaning for a keyboard, such as microfiber. If the portable mobile device accessory 10 is intended to be used as a mouse pad, a first layer 11 may be formed of a material that has a surface enhancing the usability of a mouse such as fabric, plastics, recycled rubber tires, neoprene, silicone rubber, leather, glass, cork, wood, aluminum, stone and stainless steel, optionally with an additional layer of fabric bonded to the upper surface.
If the portable mobile device accessory 10 is intended to be used as a wrist rest for a keyboard, a first layer 11 may be formed of a material which can be used for a wrist rest for a keyboard, such as gel (e.g., polyurethane gel covered in synthetic leatherette) or foam material.
According to an embodiment of the present invention, the first layer 10 is formed of a cloth. When the first layer 10 is formed of a cloth, the portable mobile device accessory is a multi-function accessory functioning as a mouse pad, a screen cleaning cloth and a writs rest for a keyboard of a mobile device.
The term “mobile computer” or “mobile device” in the specification and the claim section includes, but is not limited to a laptop computer, a tablet PC, and a mobile phone.
The term “cloth” in the specification and the claim section means any material which can be used for cleaning a screen or a surface of a mobile device.
The term “detachably attached” to a surface in the specification and the claim section means that a material has a re-adherable strip of adhesive on one surface, designed for temporarily attaching a portable mobile device accessory to a certain surface.
The cloth can include, but not limited to, a microfiber.
The cloth can be die cut or cut into different sizes to be attached on anywhere of a mobile device such as a laptop computer or tablet PC.
Examples of material for the liquid polymer adhesive layer 12 include polyurethane and polyester.
An exemplary method of forming the polymer adhesive layer is disclosed in U.S. Pat. No. 6,613,382 which is incorporated herein by reference.
For example, the polymer adhesive layer is formed as follows:
A liquid polymer adhesive is applied onto a surface 11A of the cloth such that the liquid polymer adhesive spreads across and covers the cloth, and the liquid polymer adhesive is allowed to polymerize. Once the liquid polymer adhesive is allowed to polymerize, it forms the polymer adhesive layer 12 which is permanently bonded with the cloth surface 11A. The polymer adhesive layer 12 provides a tacky surface 12A to the cloth. The tacky surface 12A can form a temporary, removable bond with the surface of a mobile device, and yet be readily peel-removed without harming the surface or leaving a residue. The tacky surface 12A of the polymer adhesive layer 12 can also be washed with water to remove dust and other contaminants to restore the tacky consistency of the polymer adhesive layer 12.
Since the portable mobile device accessory 10 has a tacky surface 12A, it can be attached to anywhere of a mobile device.
Since the mobile device accessories 10 are thin, the laptop computer is closed easily without removing the mobile device accessories 10.
For example, the thickness of the mobile device accessory according to an embodiment of the present invention is in the range of 0.5 mm to 5 mm, for example, 0.5 mm to 3 mm, specifically, 1 mm to 3 mm.
The portable mobile device accessory 10 can be used as a screen cleaning cloth, a mouse pad and/or a wrist rest.
To be used as a screen cleaning cloth, the portable mobile device accessory 10 detachably attached to a mobile device is peeled off from the mobile device, and the detached cloth 10 can be used for getting rid of dust or finger print on the screen.
Once it is cleaned, the portable mobile device accessory 10 can be attached to the original position or anywhere of laptop/tablet PC.
To be used as a wrist rest mouse pad, the portable mobile device accessory according to an embodiment of the present invention can be modified as shown in FIG. 3A or 3B. That is, the cloth 11 may have two different thicknesses as shown in FIG. 3A. Alternatively, the polymer adhesive layer 12 may have two different thicknesses as shown in FIG. 3B. The protruded surface 11C can function as a wrist rest, and the non-protruded portion 11B can function as a mouse pad.
To be used as a wrist rest for a keyboard, a single portable mobile device accessory may be detachably attached right below a keyboard of the laptop computer. If there is a touch pad right below a keyboard, a plurality (e.g., a pair) of the mobile device accessories 10 may be detachably attached right below a keyboard of the laptop computer 31 as shown in FIG. 4.
As described above, the tacky surface of the portable mobile device accessory according to an embodiment of the present invention can be washed (for example, with water or wet-towel) to clean the tacky surface, and the cloth surface can be washed as well. Accordingly, the portable mobile device accessory can be used long without losing the tackiness.
When the mobile device accessories are positioned as shown in FIG. 4, they can function as a screen cleaning cloth, a (wrist rest) mouse pad and a wrist rest for a keyboard. However, the attached position and the number of the pieces of the portable mobile device accessories can be varied according to a user's preference. For example, the portable mobile device accessory can be attached only to a right next to a touch pad of a laptop computer for a purpose of a (wrist rest) mouse pad as well as screen-cleaning.
Alternatively or additionally, the portable mobile device accessory 10 can be detachably attach to an outside surface of a laptop computer 31 as shown in FIG. 5.
Likewise, when the portable mobile device accessory 10 is used for a tablet PC, it can be attached to any surface of a tablet PC. FIG. 4 shows one example of a tablet PC 32 having a portable mobile device accessory 10.
Thus, a portable mouse pad, screen cleaner and wrist rest (three-in-one) can be carried easily on a mobile device such as a laptop computer and a table PC.
Even though it is one product, it can be used as three different products at the same time.
According to another embodiment of the present invention, an accessory 70 can be used a screen cleaner as well as a stand. The accessory 70 that can be used a screen cleaning cloth may have fold lines so that it can have a T shape when it is folded according to the fold line. For example, the fold lines may include three vertical lines 71, 72, 73 as shown in FIG. 7A. The fold line may be any line to make the screen cleaner easily folded according to the fold lines. For example, the fold lines may be line of small slits so that the screen cleaner can be easily folded. For example, the fold line may be a portion of the screen cleaning cloth in which the thickness of the screen cleaning cloth is smaller than that of the other parts of the screen cleaner. The thinner thickness may be made when the screen cleaner is made, or by pressing the portion of the screen cleaner. Alternatively, the fold line may be made by keeping the screen cleaner folded for long so that it may have a tendency to be reverted into the folded shape when it is unfolded.
FIG. 7B illustrates how the screen cleaner can be used as a stand for supporting a mobile phone. To be used as a screen cleaning cloth, the accessory 70 detachably attached to a mobile device (S1) is peeled off from the mobile device, and the detached cloth 70 can be used for getting rid of dust or finger print on the screen. (S2)
Once it is cleaned, the accessory 70 can be attached to the original position or anywhere of laptop/tablet PC or a mobile phone.
To be used as a stand, the accessory 70 having three vertical fold lines 71, 72, 73 is folded by simply attaching the fold line 71 and the fold line 73 to make it T shape. (S3 and S4) The T-shaped accessory is placed on the lower middle part of the mobile device such as a smartphone with push/snap. (S5 and S6)
Examples of material for the accessory include polyurethane and polyester.
According to an embodiment of the present invention, since the accessory 70 has a first surface which is to clean a surface and a second surface to which a polymer adhesive layer with a re-adherable strip of polymer adhesive designed for temporarily attaching the mobile device accessory to a surface of the mobile device, the accessory has a tacky surface so that it can be attached to anywhere of a mobile device. When the accessory loose stickiness, it can be washed off the dust with water or wet-towel. (S7)
According to another embodiment of the present invention, an accessory 80 can be used as a screen cleaner as well as a stand. The accessory 80 that can be used a screen cleaning cloth may have a cut. The cut has a shape to make the portion of the accessory support a mobile device when the cut portion is raised from the other part of the accessory 80. Exemplary shapes of the cut include ∩, Λ, or
, but are not limited thereto. To more securely hold the mobile device, the cut may have a shape so that two portions opposite to each other are raised to hold the mobile device 82. For example, the cut 81 may have an H shape as shown in FIG. 8A, but is not limited thereto. FIG. 8B is a side view when the screen cleaning cloth is used as a stand, and 8C illustrate how the accessory can be used as a screen cleaner as well as a stand.
FIG. 9 illustrates a portable mobile device accessory according to an embodiment of the present invention that can be used for protecting a mobile device from drops and scratches.
