## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an information appliance assembly, and more particularly to a wall-mounted information appliance assembly which enables switching of orientations of an information appliance.
2. Description of the Related Art
With the development of information technology, more and more information appliances are produced to facilitate our home and office life. As we enjoy the convenience of the information appliances, we have to face the problem of limited room relative to diverse information appliances. Therefore, the information appliances are often attached to a wall of a house to save room.
An information appliance, such as an LCD monitor or an LCD TV, is conventionally attached to the wall with a plurality of screws. However, it is boring to unscrew the screws before taking off the information appliance.
To address the aforesaid problem, Taiwan Patent No. 537477 discloses a mechanism to attach an information appliance to a wall. The mechanism comprises a first bracket adapted for being fixed to the wall, and a second bracket adapted for being fixed to a rear of the information appliance. A pair of slots is defined in opposite flanges of the first bracket, and a pair of catches is formed on opposite flanges of the second bracket corresponding to the slots of the first bracket. The information appliance is attached to the wall with the catches engaging in the slots. However, such mechanism can only hold the information appliance in a given orientation. It is impossible to switch attachment orientations of the information appliance according to different orienting needs.
Thus, an information appliance assembly which overcomes the above-mentioned problems is desired.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a wall-mounted information appliance assembly which enables switching orientations of an information appliance.
A further object of the present invention is to provide a wall-mounted information appliance assembly which facilitates attachment and detachment of the information appliance.
To achieve the above objects, an information appliance assembly in accordance with the present invention comprises an information appliance, a pivot base, and a fastener. The information appliance defines a recess in a bottom wall thereof, the recess comprising a plurality of spaced indents in the bottom wall. A plurality of spaced projecting portions is formed on the pivot base, and the projecting portions are at least partly engaged in the recess. Each of the projecting portions comprises at least one tooth. The fastener is for attaching the pivot base to a wall. The information appliance is attached to the pivot base, and is switchable between attachment orientations with the indents of the information appliance being selectively engaged with the teeth of the pivot base.
Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of a preferred embodiment of the present invention with the attached drawings, in which:

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, an information appliance assembly comprises an information appliance 10, a pivot base 30, and a fastener, such as a screw 40. The information appliance assembly is to be attached to a support, such as a wall 50.
The information appliance 10 comprises a base 13, and a cover 11. The base 13 comprises a bottom wall 130. Referring to FIG. 2, a recessed panel 133 is formed inside the base 13 in parallel with the bottom wall 130. The recessed panel 133 is generally cross-shaped, and comprises four protrusions 1331. A connecting member 134 is formed from a junction of each two neighboring protrusions 1331 to integrate the recessed panel 133 with the bottom wall 130. A generally cross-shaped recess 132 is defined in the bottom wall 130 at the recessed panel 133, and a contour of the recess 132 corresponds to a contour of the recessed panel 133. That is, the recess 132 comprises four indents (not labeled) at four ends thereof respectively, corresponding to the protrusions 1331 of the recessed panel 133. A gap 136 is defined between each protrusion 1331 and the bottom wall 130.
The pivot base 30 comprises a cylinder portion 31 with a through hole 32 defined therein. The through hole 32 is for extension of the screw 40. Four longitudinal projecting portion 33 are formed around the cylinder portion 31, corresponding to the recess 132 of the information appliance 10. Each projection portion 33 defines a plurality of dents thereby forming a plurality of spaced teeth 35, corresponding to the gaps 136 of the information appliance 10 respectively. The teeth 35 are slanted toward a predetermined direction, for facilitating entry into the recess 132. A plurality of slots 36 is defined in the cylinder portion 31 and in communication with the through hole 32, for providing more flexibility to the pivot base 30. Each slot 36 is defined along an axial direction and between each two neighboring projecting portions 33 respectively.
FIGS. 3 and 4 show one end of the pivot base 30 is received in the recess 132 of the base 13. First/outmost teeth 35 of the pivot base 30 are accommodated in the gaps 136 of the base 13. The bottom wall 130 is sandwiched between first and second teeth 35 of the pivot base 30.
Referring to FIG. 5, in use of the information appliance assembly, the screw 40 is inserted through the through hole 32 and fixes the pivot base 30 to the wall 50. The information appliance 10 is then vertically aligned with and pressed toward the pivot base 30. The end of the pivot base 30 is squeezed into the recess 132 of the information appliance 10. In detail, the first teeth 35 of the pivot base 30 are resiliently deformed to exceed the bottom wall 130, then the first teeth 35 rebound to enter the corresponding gaps 136 of the information appliance 10 respectively. The bottom wall 130 of the information appliance 10 is sandwiched between the first and second teeth 35 of the pivot base 30. The information appliance 10 is thus attached to the wall 50. In detaching the information appliance 10 from the pivot base 30, the information appliance 10 is pulled away from the pivot base 30, the first teeth 35 are deformed and disengaged from the gaps 136 of the bottom wall 130.
If desired, the information appliance 10 is detached from the pivot base 30, and is rotated 90 degrees. The information appliance 10 is then horizontally attached to the wall 50. In the preferred embodiment, the attachment of the information appliance 10 can be switched in four different orientations.
While the present invention has been illustrated by the description of the preferred embodiment thereof, and while the preferred embodiment has been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications within the spirit and scope of the present invention will readily appear to those skilled in the art. Therefore, the present invention is not limited to the specific details and illustrative examples shown and described.
