ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a detachable wrist rest for a keyboard.
2. Description of Related Art
A prior art wrist rest for a keyboard, such as disclosed in a Taiwanese Pat. Publication No. 233,824, has many drawbacks. It is known that the wrist rest has a curved outer surface toward a keyboard user is a better design for easing the contact between muscle and wrist. However, the wrist rest of such prior art is generally shaped upwardly toward the user. As such, user may feel a musculoskeletal discomfort. Further, the length of wrist rest is generally equal to that of the keyboard. As such, wrist may suspend in the air when operating the keys near left or right side of the keyboard, i.e., wrist is not supported by wrist rest. In addition, wrist rest is separated from keyboard as such wrist rest is prone to slidingly move or fall to ground inadvertently. Lastly, wrist rest is securely attached to keyboard when assembled as opposed to separately assemble due to the disassembly of wrist rest and keyboard is difficult. As such, container for packing wrist rest and keyboard is relatively large, resulting in an increase in the manufacturing cost.
Thus, it is desirable to provide an improved detachable wrist rest for a keyboard to overcome the above drawbacks of prior art.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a detachable wrist rest for a keyboard having a generally U-shaped body with the recessed portion conformed to and firmly attached to the lower part of keyboard by a pair of snap based mechanisms, i.e., the length of wrist rest is longer than that of keyboard for preventing wrist from suspending in the air when operating the keys near left or right side of keyboard. Wrist rest has a curved portion toward a keyboard user for easing the contact between muscle and wrist. Wrist rest may rotatably move to top of keyboard after assembled in order to facilitating packing and thus container for packing wrist rest and keyboard is relatively small, resulting in a reduction in the manufacturing cost.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
