ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a support device, and more particularly to a support device for a keyboard.
2. Description of the Prior Art
Typical keyboards are directly supported on the computer tables and may not be adjusted according to the sizes of various users.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional keyboard supports.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a keyboard support device which may be easily adjusted to different height according to the user's size and need.
In accordance with one aspect of the invention, there is provided a keyboard support device comprising a base, a frame including a first end pivotally secured to the base at a pivot pin, and including a second end having a curved groove formed therein, a support pivotally secured to the frame at a pivot axle and including a curved groove formed therein and aligned with the curved groove of the frame, a link including a first end pivotally secured to the base at a pivot shaft and including a second end, and a fastener device engaged through the curved grooves of the support and of the frame and engaged through the second end of the link for releasably securing the support to the frame and the link.
The fastener device includes a bolt engaged through the curved grooves of the support and of the frame and engaged through the second end of the link and includes a knob threaded to the bolt for releasably securing the support to the frame and the link. One or more spacers are further engaged between the link and the support. The bolt includes a first end extended outward of the support, the fastener device includes a sleeve engaged on the bolt and engaged between the knob and the support.
The fastener device includes a bar secured between the pivot axle and the bolt, the bar includes a non-circular cavity formed therein, the bolt includes a non-circular latch formed thereon and engaged with the cavity for securing the bolt to the bar and for preventing the bolt from rotating relative to the support.
A spring biasing means is further provided for biasing the frame and the link to rotate relative to the pivot pin and the pivot shaft respectively and to elevate the support relative to the base. The biasing means is engaged between the pivot shaft and the frame. The frame includes an ear extended therefrom, the biasing means is engaged between the pivot shaft and the ear of the frame.
The biasing means includes a barrel, and a tube slidably received in the barrel, and a spring engaged between the barrel and the tube for biasing the tube outward of the barrel. The barrel of the biasing means includes a hook for detachably securing to the pivot shaft. The tube includes a projection for detachably engaging with the ear of the frame.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
