## Background
(a) TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to a detachable keyboard structure, and more particularly to a detachable keyboard structure that provides a protection cover and a wrist protector pad to a notebook computer keyboard with a simple arrangement.
(b) DESCRIPTION OF THE PRIOR ART
Technology and information have been increasingly advanced and developed. Computer devices and peripherals thereof have been widely used. Taking a notebook computer as an example, a keyboard is widely used as an interface of operation for the notebook computer and becomes an indispensable hardware peripheral device. A conventional notebook computer usually comprises a keyboard that is unitarily formed with the computer itself. However, to some extents, the keyboard may be considered consumables, which require cleaning, maintenance, or even replacement after use for a long while or being accidently stained. Thus, there is an increasing demand for a detachable keyboard for the notebook computers.
Further, due to being constrained by the small size of a notebook computer, the conventional detachable keyboard may not be operated by a user in an ergonomic manner. The wrists of the user may readily get hurt for long term uses of the computer. Thus, the number of users is increasing in using a wrist protection board in operating a keyboard in order to protect the wrists against undesired hurting. However, since the keyboard and the wrist protection board are individual and separate parts, when not in use, the wrist protection board occupies quite an amount of space, and when in use, it must be first assembled with the keyboard, leading to inconvenience of use. Thus, although the wrist protection board helps protect the wrists of the user, the use of the wrist protection boards is not prevailing.
Thus, there are still issues for further improvement of the conventional keyboards of notebook computers, which will be briefed as follows:
(1) Although a detachable keyboard usable with a notebook computer is commonly known, heretofore, the notebook computer keyboard does not offer a function of protection.
(2) Typing with a notebook computer may readily hurt the wrists; however, the use of a conventional wrist protection board is inconvenient.
SUMMARY OF THE INVENTION
In view of the above problems and drawbacks, the present invention aims to provide a detachable keyboard structure that provides a protection cover and a wrist protector pad to a notebook computer keyboard with a simple arrangement.
The primary object of the present invention is thus to provide a detachable keyboard of a notebook computer with functions of dust protection and wrist protection, but not affecting the convenience of use of the keyboard.
To achieve the above object, the present invention provides a structure that comprises: a keyboard assembly that is selectively mounted to a notebook computer. A movable cover is movably mounted to one side of the keyboard assembly. A least one flexible bendable section connects the keyboard assembly and the movable cover to each other. A positioning member is rotatably mounted to one side of the movable cover that is distant from the flexible bendable section for fixing the movable cover to one side of the keyboard assembly. The present invention is structure to allow a user to use the detachable keyboard assembly to replace a keyboard of the notebook computer. Before the replacement, the movable cover may be used to provide a function of dust and contamination protection for the keyboard assembly, and the positioning member may fix the movable cover to the keyboard assembly for easy carrying. And, to use, through the flexible bendable section, the movable cover is rotated, in a reversed direction, to one side of the keyboard assembly with the positioning member being further rotated to the underside of the movable cover to provide support, so that the movable cover may function as a support for wrist of a user. As such, the functionality of protection of the detachable keyboard is increased and easy replacement may be conducted when the keyboard is broken for reducing expenditure. In addition, the chance that a user may hurt the wrists for long-term use of the keyboard may be reduced.
With the above-described technology, the problems that the prior art notebook computer keyboards cannot feature ready detachment, easy cleaning and protection, and lacking ergonomics can be overcome and properly solved.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Referring to FIGS. 1-4, the drawings clearly show that the present invention comprises:
a keyboard assembly 1 that is selectively mounted to a notebook computer 6, the keyboard assembly 1 having one end to which at least one coupling section 11 is provided for coupling and fixing to the notebook computer 6;
a movable cover 2 that is movably mounted to one side of the keyboard assembly 1;
at least one flexible bendable section 3 that connects the keyboard assembly 1 and movable cover 2 to each other;
a positioning member 4 that is rotatably mounted to one side of the movable cover 2 that is distant from the flexible bendable section 3 for fixing the movable cover 2 to one side of the keyboard assembly 1, the positioning member 4 comprising a support section 41 rotatably mounted to the movable cover 2 and a limiting section 42 extending from one side of the support section 41 for being selectively retained to one side of the keyboard assembly 1 or being supported on one side of the notebook computer 6; and
a pivot section 5 that is mounted to one side of the positioning member 4 and comprises a dual hinge arrangement to allow the positioning member 4 to rotate at one side of the movable cover 2.
The above description provides an explanation of the structure of the present invention and with components of the structure combined properly, a simple arrangement may be achieved for providing a keyboard protection cover and a wrist protection pad for the notebook computer 6, which will be described in more details in the following.
As shown in FIGS. 1-6A, with a structure constructed as above, it can be clearly seen from the drawings that the keyboard assembly 1 of the present invention comprises at least one coupling section 11 for selectively mounting to a notebook computer 6 in such a way as to be easily replaceable so that the keyboard assembly 1 that is mounted to the notebook computer 6 can be replaced individually when broken thereby helping lower down the necessary expenditure and in addition, a flexible bendable section 3 is included for connection with a movable cover 2, which allows a user to use in different ways so as to provide various additional functions to the keyboard assembly 1. Further, the movable cover 2 is directly coupled to the keyboard assembly 1 by the flexible bendable section 3 so that storage is easy and occupies no large amount of space and the issue of losing or leaving behind can be eliminated.
In practical use, coupling between the keyboard assembly 1 and the notebook computer 6 can be efficiently accomplished by means of the coupling section 11. The coupling can be one of slot fitting, snap fitting, tenon engagement, magnetic retention, and adhesive attachment. When not in use, the keyboard assembly 1 is protected against dust and contamination by having the movable cover 2 set on and covering a surface of the keyboard assembly 1. The positioning member 4 is rotated via the pivot section 5 to have the limiting section 42 of the positioning member 4 to fix a movable edge of the movable cover 2 to one side of the keyboard assembly 1 for preventing it from loosening during movement. To use, the movable cover 2 is rotated via the flexible bendable section 3 to have the surface thereof that is opposite to the keyboard assembly 1 rotated in a reversed direction and the positioning member 4 is rotated by an even larger range by means of the dual hinge structure of the pivot section 5 so that the support section 41 gets positioned against one side of the movable cover 2. The movable cover 2 may then be laid flat on one side of the keyboard assembly 1 with the limiting section 42 abutting one side of the notebook computer 6 to securely hold the movable cover 2 in position without undesired sliding or moving. A user may use such a structure as a wrist protection pad with the positioning member 4 firmly supporting the movable cover 2 at an angular position that is considered ergonomic to the user.
As shown in FIG. 7, it can be seen from the drawing that the instant embodiment is similar to the embodiment described above and the difference resides in that at least one protection cushion pad 21a is provided at one side of the movable cover 2a that is adjacent to the keyboard assembly 1a. The protection cushion pad 21a helps improve tactile perception of softness and conformableness when the movable cover 2a serves as a wrist protection pad and also prevent direct contact of the movable cover 2a that may be rigid and hard with the keyboard assembly 1a or the display screen when the movable cover 2a serves as a protection cover. Alternatively, the movable cover 2a may be made of a soft material to provide better performance and use.
Referring to all the drawings, the present invention, when compared with the prior art, provides the following advantages:
(1) The structure is simple; the operation is easy; and efficient and fast replacement of the keyboard assembly 1 can be achieved.
(2) Functions of dust and contamination protection and wrist protection can be alternatively achieved through rotation of the movable cover 2.
(3) Direct coupling to the keyboard assembly 1 is available for easy storage and carrying.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
