DETAILED DESCRIPTION OF THE INVENTION

[0017] Referring to FIG. 1 and FIG. 2, a multipurpose stationery tool in accordance with the present invention is shown. The multipurpose stationery tool comprises a base 10, a supporting unit 20 and an upper holder block 30, and is adapted for holding an article such as, for example, a pack of convenience stickers 40.

[0018] The base 10 is a plate member extending in a longitudinal direction X, comprising a first end 11, a pair of pivot holders 12 mounted at the first end 11 and spaced in a transverse direction Y perpendicular to the longitudinal direction X, a pair of first position-limiting portions 13 respectively disposed in the pivot holders 12 at one side, a pair of second position-limiting portions 14 respectively disposed in the pivot holders 12 at an other side, a second end 15 extended in the longitudinal direction X opposite to the first end 11, a top wall 16 extended from the first end 11 to the second end 15, and a recessed accommodation chamber 17 defined in the top wall 16 and extended from the second end 15 toward the first end 11. Referring also to FIG. 7, each pivot holder 12 comprises two upright pivot support plates 121 spaced in the transverse direction Y, a pivoting space 122 defined between the two upright pivot support plates 121, and a pivot hole 123 located in each upright pivot support plate 121. The first position-limiting portions 13 are plate-shaped components protruded from the top wall 16. Further, these first position-limiting portions 13 are respectively abutted to the pivoting spaces 122 in the pivot holders 12 and respectively connected with the upright pivot support plates 121 of the pivot holders 12 to exhibit an inverted-U shape. The second position-limiting portions 14 are respectively located at two opposite lateral sides of the top wall 16 and substantially disposed in parallel to the top wall 16. The pivoting spaces 122 are adapted for securing the supporting unit 20 in a pivotable manner to hold down the pack of convenience stickers 40.

[0019] The supporting unit 20 is adjustable in position relative to the base 10, comprising a pair of support bars 21 each having a pivoting portion 22 located at one end thereof and pivotally connected to one respective pivot holder and a swinging portion 23 located at an opposite end thereof. Referring also to FIG. 7, the pivoting portions 22 of the supporting unit 20 are spherical shaped members respectively pivotally accommodated in the pivoting spaces 122, having two opposite lateral sides of the periphery thereof protruding in the respective pivot holes 123 so that the pivoting portions 22 are rotatable in all directions relative to the respective pivot holders 12. The swinging portions 23 of the supporting unit 20 are spherical shaped members (the swinging portions 23 and the pivoting portions 22 substantially have the same shape; in order to simplify the drawings, the structures at both ends of the support bar 21 are combined together and shown in FIG. 7).

[0020] The upper holder block 30 is adjustable in position relative to the supporting unit 20, comprising a holder block base 31, a pair of extension rods 32 bilaterally extended from one side of the holder block base 31, a positioning plate 33 extended from an opposite side of the holder block base 31, two pivotal couplings 34 located at a bottom side of the holder block base 31 and spaced in the transverse direction Y and respectively pivotally connected to the swinging portions 23 of the supporting unit 20, and two stop portions 342 respectively located at the pivotal couplings 34 at one side (the shape and structure of the pivotal couplings 34 are substantially same as the pivot holders 12; in order to simplify the drawings, the structure of the pivotal couplings 34 is combined into FIG. 7). The pivotal couplings 34 each comprise two side panels 341 spaced in the transverse direction Y and a pivoting space 343 defined between the two side panels 341. The stop portions 342 are plate shaped members protruded from the holder block base 31. Further, the stop portions 342 are respectively disposed abutted to the respective pivoting spaces 343 at one side, and respectively connected with the respective side panels 341. The side panels 341 each have a through hole 344. The swinging portions 23 have two opposite lateral sides of the periphery thereof protruding in the respective through holes 3444 so that the swinging portions 23 are rotatable in all directions relative to the respective pivotal couplings 34.

[0021] As illustrated in FIG. 1 and FIG. 3, when the supporting unit 20 is moved relative to the base 10 to a extended position, the first position-limiting portions 13 stop the pivoting portions 22 in position, supporting the support bars 21 in vertical relative to the top wall 16 and prohibiting the support bars 21 from moving relative to the pivot holders 12 in a counter-clockwise direction in FIG. 3. When the supporting unit 20 stands in the extended position, the stop portions 342 of the upper holder block 30 provide a position-limiting effect to the swinging portions 23, holding the extension rods 32 in substantially parallel relationship with the top wall 16 and prohibiting the holder block base 32 from moving relative to the support bars 21 in the clockwise direction in FIG. 3.

[0022] When in the extended position shown in FIGS. 1 and 3, the multipurpose stationery tool presents a treadmill model in its appearance, increasing the fun of the use of the multipurpose stationery tool and allowing the user to take one convenience sticker from the pack of convenience stickers 40 in the recessed chamber 17. Thus, the multipurpose stationery tool can secure the pack of convenience stickers 40 positively in place, making the pack of convenience stickers 40 not be easily concealed or lost.

[0023] Referring to FIG. 4 and FIG. 5, when the user moves the supporting unit 20 relative to the base 10 from the extended position to a received position, the upper holder block 30 is positioned to about a 90-degree angle relative to the supporting unit 30 so that the swinging portions 23 and the upper holder block 30 are disposed in proximity to the top wall 16. At this time, the pivotal couplings 34 are abutted against the second position-limiting portions 14, keeping the supporting unit 20 and the upper holder block 30 constantly in the received position. In this received position, the dimension of the multipurpose stationery tool is minimized, facilitating packaging and carrying.

[0024] Referring to FIG. 6, when the multipurpose stationery tool is in the extended position, the multipurpose stationery tool can be turned through 90-degree angle placed with the supporting unit 20 on a tabletop to keep the base 10 in a vertical position relative to the tabletop. At this time, the base 10 is used as a back support to support a mobile electronic device 50 (such as mobile phone or tablet computer), the extension rods 32 of the upper holder block 30 are used as stop members to stop one end of the mobile electronic device 50 in place, and the positioning plate 33 is used as a positioning member to abut against the tabletop, enhancing positioning stability.

[0025] Thus, subject to the pivotable arrangement of the base 10, the support unit 20 and the upper holder block 30, the multipurpose stationery tool of the present invention utilizes can be conveniently set between the extended position for holding a pack of convenience stickers 40 or a mobile electronic device 50 and the received position for packaging or carrying. Further, when the multipurpose stationery tool is set in the extended position, it presents a treadmill model to provide added value.

[0026] Further, as illustrated in FIG. 7, subject to the design that the pivoting portions 22 and the swinging portions 23 are spherical, the pivot holes 123 of the upright support plates 121 are configured to support the respective pivoting portions 22 in a pivotable manner, and the through holes 344 of the side panels 341 are configured to support the respective swinging portions 23 in a pivotable manner in all directions, there are non-directional mounting restrictions when assembling the multipurpose stationery tool. Further, mounting and dismounting the multipurpose stationery tool can easily be achieved by plugging the pivoting portions 22 and the swinging portions 23 into the respective pivoting spaces 122 or 343, or pulling the pivoting portions 22 and the swinging portions 23 out of the respective pivoting spaces 122 or 343, i.e., the mounting and dismounting of the pivoting portions 22 relative to the pivot holders 12 and the mounting and dismounting of the swinging portions 23 relative to the upper holder block 30 are quite simple. Further, the component parts of the multipurpose stationery tool are inexpensive to manufacture.

[0027] As described above, the multipurpose stationery tool of the present invention has the characteristics of simple structure and ease of manufacturing, accurately achieving the objects of the present invention.

[0028] Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
