Supporting easel for notebook computer

Abstract

A supporting easel for notebook computer includes two front legs pivotally jointed with one end of a shaft collet at symmetrical positions, and two rear legs also pivotally jointed with another end of the shaft collet at symmetrical positions. The front leg is sleeve-jointed with two shanks. A vertical three-way T-pillar is arranged on a front edge of a shank of the front leg, and an upwardly bent terminal is formed at a tail end of the rear leg. By turning the front legs and the rear legs, the supporting easel can be spread wider left and right, then by adjusting the front legs, a suitable length of the front legs could be found such that a notebook computer can be laid on the supporting easel in an ergonomic inclination angle with its front and rear walls fixed flush to the supporting easel.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a supporting easel for notebook computer, and particularly to a supporting easel for notebook computer, which could be adjusted rotationally and extendedly.

2. The Prior Arts

The notebook computer available in market today is very compact and portable, however, the display thereof is found unsuitable in some cases, too short in height for example, and further, when a subordinate keyboard is laid flatted on the desktop, it may result in an ache of wrist and/or elbow. Besides, the heat discharge of a notebook computer is considered a big problem that always needs improvements as the execution speed of CPU is getting faster and faster, and unfortunately, the USB card and/or the network card seems liable to blockade the air inlet of the notebook computer such that heat inside cannot be discharged smoothly that would usually cause a “computer crash.”

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a supporting easel for notebook computer, whereby a notebook computer could be well furnished in a desired angle.

Another object of the present invention is to provide a supporting easel for notebook computer, whereby, the wrist ache caused by a lying-flat keyboard can be cured.

Yet another object of the present invention is to provide a supporting easel for notebook computer, whereby the intake blockaded by wiring to deteriorate heat discharge and air convection effect could be improved.

In order to realize above objects, two front legs are pivotally jointed with one end of a shaft collet at symmetrical positions, and two rear legs are also pivotally jointed with another end of the shaft collet at symmetrical positions. The front leg is sleeve-jointed with two shanks. A vertical three-way T-pillar is arranged on a front edge of a shank of the front leg, and an upwardly bent terminal is formed at a tail end of the rear leg. By turning the front legs and the rear legs, the supporting easel can be spread wider left and right, then by adjusting the front legs, a suitable length of the front legs could be found such that a notebook computer can be laid on the supporting easel in an ergonomic inclination angle with its front and rear walls fixed flush to the supporting easel.

The merits of the present invention may be summarized as the following: Since the symmetrical front and rear legs are pivotally jointed with a shaft collet, in which the front legs are adjustable in length and provided with three-way pillars at front edge thereof; and an upwardly bent terminal is formed at a tail end of each rear leg, such that a notebook computer can be laid flat on the supporting easel of the present invention in a proper inclination angle that makes a user feel comfortable in using this computer. Besides, such an ergonomic design can also improve the heat discharge of the computer.

For more detailed information regarding advantages or features of the present invention, at least one example of preferred embodiment will be described below with reference to the annexed drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 3 is a perspective view of the supporting easel of the present invention in another expanded condition;

FIG. 4 is a cross-sectional view showing a front leg of the supporting easel of the present invention in use;

FIG. 5 is another cross-sectional view showing the front leg of the supporting easel of the present invention in use; and

FIG. 6 is a cross-sectional view of an assembled front leg of the supporting easel of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As illustrated in FIGS. 1-4, the present invention relates to a supporting easel A for notebook computer.

The supporting easel A comprises two front legs 1 pivotally jointed with one end of a shaft collet 3 at symmetrical positions and two rear legs 2 also pivotally jointed with one end of a shaft collet 3 at symmetrical positions. The front leg 1 comprises a first shank 11 and a second shank 12. A slide rail 111 is formed on a bottom edge of the first shank 11. A slide groove 122 at a position corresponding to the slide rail 111 is formed in the bottom edge of the second shank 12. A front edge of the second shank 12 is a vertical T-pillar 121. The first shank 11 is sleeve-jointed to the second shank 12, and the slide rail 111 can be snap-fastened in the slide groove 122. A tubular sheath 13 is sheathed on the second shank 12. A thimble 14, which is arranged inside the tubular sheath 13, is screw-jointed with the first shank 11 to lock the shanks together. Moreover, a terminal 21, which is bent upward, is formed at a tail end of the rear leg 2.

Also referring to FIGS. 4-6, when using the present invention, a user is supposed first to turn two rear legs 2, which are pivotally jointed with the shaft collet 3 of the supporting easel A, and spread them outwardly until they are checked in a rear wall 31 of the shaft collet 3, and then, turn two front legs 1, which are pivotally jointed with the shaft collet 3 of the supporting easel A, and spread them outwardly until they are checked in a lateral wall 32 of the shaft collet 3. After a backwardly inclined X-structure is formed, the user should release the tubular sheath 13 of those two front legs 1 and pull the second shank 12 forwardly to extend it to a proper distance, then lock the tubular sheath 13 tightly such that the thimble 14 therein would depress and fix the second shank 12 to thereby carry out the adjustment of length of the front legs 1. Now, a user may put a notebook computer (not shown) flat on the supporting easel A, then tip it in a suitable angle, align its front and rear sides flush with the three-way pillar 121 of the front legs 1 and the upwardly bent terminal 21 of the rear legs 2 respectively, so as to set the notebook computer in place.

In the above described, at least one preferred embodiment has been described in detail with reference to the drawings annexed, and it is apparent that numerous changes or modifications may be made without departing from the true spirit and scope thereof, as set forth in the claims below.
