ADJUSTABLE STAND HOLDER

An adjustable stand holder includes a stand base including a base frame, an axle holder and a guide track arranged at the base frame at right angles, a cover member including a cover frame pivotally coupled to the axle holder and a smoothly curved stop flange raised from a front side of the cover frame for supporting a mobile electronic device on the cover frame, and a wheel receivable in the stand base and mountable between the base frame and cover frame to support the cover member in a tilted position relative to the stand base and movable along the guide track to adjust the tilting angle of the cover member relative to the stand base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring toFIGS. 1-3, an adjustable stand holder in accordance with the present invention is shown. The adjustable stand holder comprises a stand base1, a cover member2, and at least one wheel3.

The stand base1comprises a base frame11defining a high front low back top wall111, an opening110cut through the base frame11and surrounded by the high front low back top wall111, an accommodation chamber14formed in the high front low back top wall111in a middle rear position relative to and in communication with the opening110, an axle holder12transversely mounted at the high front low back top wall111in a middle front position relative to the opening110and opposite to the accommodation chamber14and defining therein an axial hole120, a rotary axle121inserted through the axial hole120of the axle holder12and defining a locating notch122on the periphery of each of two opposite ends thereof, at least one, for example, two guide tracks13formed in the high front low back top wall111at two opposite lateral sides of the opening110in a parallel manner, and a plurality of cushion pads15mounted in corners of the bottom side of the base frame11. Further, each guide track13defines a sliding groove130, two smoothly arched bearing surfaces131respectively located at opposing front and rear ends of the sliding groove130, and a positioning groove132formed in the smoothly arched bearing surface131at the front end of the sliding groove130.

The cover member2comprises a cover frame21defining a high front low back bottom wall211, an opening210cut through the cover frame21and surrounded by the high front low back bottom wall211, a smoothly curved stop flange22raised from the top surface of the cover frame21at a front side relative to the opening210, a bottom recessed hole23located at the high front low back bottom wall211of the cover frame21corresponding to the smoothly curved stop flange22, two axle holes231formed in the cover frame21at two opposite lateral sides of the bottom recessed hole23and aligned in line, two stop blocks232bilaterally disposed in the bottom recessed hole23and spaced below the axle holes231, and at least one, for example, two longitudinal locating ribs24protruded from the high front low back bottom wall211and extending in a parallel manner at two opposite lateral sides relative to the opening210.

The wheel3comprises a metal circular wheel body31defining a rim311around an outer perimeter thereof, and an anti-slip covering32mounted around the metal circular wheel body31and stopped in place by the rim311. Further, the anti-slip covering32defines a locating groove321that is forced into engagement with the rim311. The anti-slip covering32can be made out of flexible rubber, having a toothed pattern formed in the outer wall thereof.

When assembling the adjustable stand holder, pivotally connect the cover frame21of the cover member2to the axle holder12of the stand base1by: moving the axle holder12of the stand base1into the bottom recessed hole23of the cover member2and then coupling the two opposite ends of the rotary axle121of the stand base1to the axle holes231of the cover member2. At this time, the cover member2can be biased relative to the stand base1to a limited angle where the locating notches122of the axle holder12of the stand base1are respectively abutted against the stop blocks232of the cover member2. Further, when biasing the cover member2relative to the stand base1, an open space20will be defined between the stand base1and the cover member2. Further, when the adjustable stand holder is not in use, the wheel3can be received in the accommodation chamber14in the stand base1. Further, the accommodation chamber14can have a circular or semi-circular profile fitting the configuration of the wheel3. Further, when the cover member2is closed on the stand base1, the high front low back bottom wall211of the cover frame21and the high front low back top wall111of the base frame11are abutted against each other, and therefore the adjustable stand holder is kept in a flat condition, reducing the height and saving storage space. Subject to the design of the opening110of the stand base1and the opening210of the cover member2, the weight and material consumption of the adjustable stand holder can be greatly reduced, convenient for carrying.

Referring toFIGS. 4-7, when using the adjustable stand holder, the adjustable stand holder can be placed on the top of a table or desk, keeping the cushion pads15in positive contact with the surface of the top of the table or desk. At this time, a mobile electronic device4(such as tablet computer, smart phone, PDA, multimedia player, etc.) can be supported on the cover frame21and smoothly curved stop flange22of the cover member2.

When going to adjust the angular position of the adjustable stand holder, lift the rear side of the cover member2to turn the cover member2about the axle holder12of the stand base1, and then take the wheel3out of the accommodation chamber14, and then insert the wheel13into the sliding groove130of one guide track13and move the wheel13to the positioning groove132at the front end of the sliding groove130, and then lower the cover member2to let the high front low back bottom wall211of the cover frame21be supported on the wheel3. At this time, the wheel3supports the cover member2and the mobile electronic device4on the stand base1in a tilted position. By means of moving the wheel3in the sliding groove130of the respective guide track13, the tilting angle of the cover member2and the mobile electronic device4is relatively adjusted. Further, the wheel3can be moved between the front and rear ends of the sliding groove130of the respective guide track13to adjust the tilting angle of the cover member2and the mobile electronic device4(the contained angle between stand base1and the cover member2) within 12˜70° angle. By means of adjusting the tilting angle of the cover member2and the mobile electronic device4subject to user's preference, the user can touch the touchscreen of the mobile electronic device4comfortably.

Further, when adjusting the tilting angle of the cover member2, the high front low back bottom wall211of the cover frame21of the cover member2is kept in friction engagement with the anti-slip covering32of the wheel3, avoiding slipping. Further, the rim311of the metal circular wheel body31of the wheel3is kept abutted against one longitudinal locating rib24of the cover member2, enhancing positioning stability and avoiding vibration.
