The present invention relates to an audio-video equipment or mobile device, and more particularly to an audio-video equipment or mobile device with an adjustable supporting arm or mechanism or assembly or the like for supporting the audio-video equipment or mobile device at a suitable or selected height or position for allowing the audio-video equipment or mobile device to be easily seen or viewed by the user.
Typical audio-visual or audio-video equipment or facilities comprise a speaker housing, a mobile electronic device, such as a portable or mobile phone, a notebook, a micro-computer, a personal computer, a screen, a displayer, a projector, or the like to be disposed or supported on the table or stand or the like.
For example, U.S. Pat. No. 10,198,720 B2 to Shi et al., U.S. Pat. No. 10,571,068 B2 to Law et al., and U.S. Pat. No. 10,623,543 B2 to Hummel et al. disclose several of the typical audio-visual or audio-video facilities having a supporting stand for supporting the audio-video equipment or mobile device at a suitable or selected height or position.
However, the supporting stand may not be used to suitably support the audio-video equipment or mobile device at a suitable or selected height or position and may not be easily seen or viewed by the user.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional audio-video or mobile devices.
The primary objective of the present invention is to provide an audio-video equipment or mobile device including an adjustable supporting arm or mechanism or the like for supporting the audio-video equipment or mobile device at a suitable or selected height or position for allowing the audio-video equipment or mobile device to be easily seen or viewed by the user.
In accordance with one aspect of the invention, there is provided a mobile device supporting assembly comprising a supporting mechanism including a base plate, a carrier plate to be supported on the base plate, and a lever attached to the base plate and adjustable relative to the base plate, and a mobile electronic facility to be supported on the carrier plate for allowing the mobile electronic facility to be adjusted relative to the base plate to any suitable or selected height and for allowing the mobile electronic facility to be easily and readily viewed or seen by the user or the like.
The lever includes a first end portion having a spindle engaged with the base plate for pivotally and adjustably attaching the lever to the base plate. The lever includes a plurality of first teeth formed on the spindle, and the base plate includes a plurality of second teeth engaged with the first teeth of the lever for frictionally adjusting the lever relative to the base plate and for allowing the lever to be frictionally anchored and positioned to the base plate at the selected or required height.
The base plate includes a barrel having the second teeth formed in the barrel, and/or the base plate includes two barrels each having the second teeth formed in the barrel. The lever includes a second end portion having an axle engaged with the carrier plate for pivotally attaching the lever to the carrier plate and for allowing the carrier plate to be adjusted relative to the base plate to any suitable or selected height.
The lever includes a plurality of first teeth formed on the axle, and the carrier plate includes a plurality of second teeth engaged with the first teeth of the lever for frictionally adjusting the lever relative to the carrier plate. The carrier plate includes a barrel having the second teeth formed in the barrel, and/or the carrier plate includes two barrels each having the second teeth formed in the barrel and engaged with the first teeth of the lever.
A supporting stand may further be provided and includes a base board, a carrier board, and a post disposed and engaged with the base board and the carrier board for supporting the carrier board above the base board at any suitable or selected height. The post includes a rod, and the base board includes an opening formed in the base board for receiving and engaging with the rod of the post. The base board includes a sucker attached to a bottom portion of the base board.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
As shown in
The spindle 21 includes two end portions each having a number of teeth 25 formed or provided thereon, and the axle 23 also includes two end portions each having a number of teeth 26 formed or provided thereon. The base plate 10 includes one or more (such as two) tubes or barrels 12 disposed or engaged therein, and the barrels 12 each include a hole or bore 13 formed therein for receiving or engaging with the spindle 21 and for pivotally or rotatably securing or connecting or coupling the lever 20 to the base plate 10.
It is preferable that the barrels 12 each include a number of teeth 14 formed or provided in the bore 13 thereof for engaging with the teeth 25 of the spindle 21 and for allowing the lever 20 to be adjusted relative to the base plate 10 to any suitable or selected angular position or to any suitable or selected included angle (A) (
Similarly, the carrier plate 11 also includes one or more (such as two) tubes or sleeves 15 disposed or engaged therein, and the sleeves 15 each include a bore or hole 16 formed therein for receiving or engaging with the axle 23 and for pivotally or rotatably securing or connecting or coupling the lever 20 to the carrier plate 11. It is also preferable that the sleeves 15 each include a number of teeth 17 formed or provided in the hole 16 thereof for engaging with the teeth 26 of the axle 23 and for allowing the lever 20 to be adjusted relative to the carrier plate 11 to any suitable or selected angular position or to any suitable or selected included angle. For example, the lever 20 may be adjusted and supported relative to the carrier plate 11 at any suitable or selected angular position with the frictional force between the teeth 26 of the axle 23 and the teeth 17 of the sleeves 15.
As shown in
It is preferable that the base board 50 includes a sucker or suction device 55 disposed or engaged in the lower or bottom portion thereof for engaging with the supporting desk or the supporting surface (not illustrated) or the like, and for allowing the supporting stand 5 to be firmly and solidly and stably supported on the supporting desk or the supporting surface (not illustrated) or the like. It is also preferable that the post 52 may be tilted or inclined relative to the base board 50 for allowing the mobile facility 30 to be suitably and selectively tilted or inclined relative to the base board 50, when required.
Accordingly, the audio-video equipment or mobile device in accordance with the present invention includes an adjustable supporting arm or mechanism or the like for supporting the audio-video equipment or mobile device at a suitable or selected height or position for allowing the audio-video equipment or mobile device to be easily seen or viewed by the user.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
