## Title
Monitor apparatus

## Abstract

A monitor apparatus includes a monitor main body and a monitor stand pivotably connected with the monitor main body. A pair of rolling members is attached to a base of the monitor main body. The monitor stand and the rolling members are seated on a same plane for supporting the monitor main body. The monitor main body is capable of rotating about an axis parallel or vertical to the plane.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to monitor apparatuses and, more particularly, to a monitor apparatus with wheels for facilitating adjusting a viewing angle of the monitor.
2. Description of Related Art
As display technology develops, monitors are developed that are increasingly smaller in volume and lighter in weight. A typical monitor apparatus includes a base member stably seated on a horizontal plane such as a desk, a monitor main body adapted to display a picture thereon, a connecting member connecting the base member to the monitor main body, and a monitor hinge connecting the upper part of the connecting member to the monitor main body. Thus, the monitor main body can be tilted upwards or downwards to a desired viewing angle. However, because of sliding friction between the base member and the plane, movement of the monitor is not smooth during angle adjustments.
Thus, a monitor apparatus which conveniently adjusts a viewing angle is desired.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Referring to FIG. 1, an embodiment of a monitor apparatus includes a monitor main body 10, a pair of holding members 20, a pair of rolling members 30, and a monitor stand 40. The monitor stand 40 includes a connecting member 50 and a base stand 80. The base stand 80 includes a main portion 60 and a cover portion 70.
Referring to FIG. 2, the monitor main body 10 includes a protruded portion 12 at a back side thereof. A pair of pivot holes 121 is respectively defined in two opposite sides of the protruded block 12. A pair of grooves 14 for receiving the holding members 20 therein is defined in a base of the monitor main body 10.
Referring to FIG. 3, a pair of pivot slots 22, 24, and an arc-shaped holding slot 26 are defined in each of the holding members 20. Each of the rolling members 30 includes a wheel and an axial post 34 extending though a central axis of the wheel 32. Two ends of the axial post 34 of the rolling member 30 engage in the pivot slots 22, 24. The wheel 32 is received in the holding slot 26 of the holding member 20 and capable of rolling in the holding slot 26.
The connecting member 50 may be symmetrically shaped and includes a pair of arm sections 52 and a pair of distal ends 54 for engaging with the pivot holes 121 of the monitor main body 10. At least one of the arm sections 52 defines a first friction structure 521. The connecting member 20 may be wire like, firm and elastic.
Referring to FIG. 4, a cross section of the cover portion 70 may be triangle-shaped. The cover portion 70 includes a top surface 74 and a side surface 76 substantially perpendicularly connecting with the top surface 74. A pair of inclined slots 72 is defined in the cover portion 70 and extends through the top surface 74 and the side surface 76 for receiving the arm sections 52 of the connecting member 50 therein. A second friction structure 721 is formed beside the inclined slots 72 to engage with the first friction structure 521 of the connecting member 50 and prevent unexpected sliding movement of the connecting member 50 along the inclined slots 72.
Referring to FIG. 5, in assembly, the arm sections 52 of the connecting member 50 are engaged in the inclined slots 72 of the cover portion 70. The cover portion 70 is secured to the main portion 60 by fasteners such as screws. The distal ends 54 of the connecting member 50 are engaged in the pivot holes 121 of the monitor main body 10. The arm sections 52 of the connecting member 50 are slidable along the slot 72 of the cover portion 70 along an inclined direction to a predetermined height. The first friction structure 521 of the connecting member 50 is engaged with the second friction structure 721 beside the slots 72 of the cover portion 70, thereby fixing the connecting member 50 at the predetermined height. The monitor main body 10 is capable of rotating about the distal ends 54 of the connecting member 50 and fixed at a desired tilting angle because of friction between the monitor main body 10 and the distal ends 54 of the connecting member 50. Two ends of the axial post 34 of each of the rolling members 30 engage with the pivot slots 22, 24 of one corresponding holding member 20. The wheel 32 of each of the rolling members 30 engages with the holding slot 26 of one corresponding holding member 20 and pivotally attaches to the base of the monitor main body 10.
To adjust an angle between the monitor main body 10 and a horizontal plane on which the monitor apparatus is seated, the monitor main body 10 is rotated downwards or upwards about a horizontal axis. Sliding movement of the arm sections 52 of the connecting member 50 along the inclined slots 72 of the cover portion 70 can also allow adjustment of the angle between the monitor main body 10 and a horizontal plane.
When rotating the monitor main body 10 right or left to adjust the viewing angle, the wheels 32 of the rolling members 30 attached at the base of the monitor main body 10 roll along the plane. In the illustrated embodiment, the rolling members 30 are symmetrically attached at two sides of the base of the monitor main body 10. A direction of the axial post 34 of the rolling member 30 is deviated from the vertical or horizontal. Thus, the monitor main body 10 smoothly and easily rotates about a vertical axis.
While the present disclosure has been illustrated by the description of embodiments thereof, and while the embodiments have been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such details. Additional advantages and modifications within the spirit and scope of the present disclosure will readily appear to those skilled in the art. Therefore, the present disclosure is not limited to the specific details and illustrative examples shown and described.
