Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a personal item and, more particularly, to a support rack.

2. Description of the Related Art

A conventional support rack in accordance with the prior art shown in FIG. 1 comprises a supporting member 11, two holders 12 extending downward from the supporting member 11 in an inclined manner, and a clamping seat 13 retractably mounted on the supporting member 11 and extending upward from the supporting member 11. When an article 14, such as a tablet computer, a book, a music score or the like, is placed on the supporting member 11 and held by the holders 12, the clamping seat 13 is pressed downward to clamp the article 14, so that the article 14 is positioned between the holders 12 and the clamping seat 13. However, the holders 12 are secured on the supporting member 11, and the distance between the holders 12 is fixed and cannot be adjusted, so that the conventional support rack has a fixed width that is suitable for an article with a fixed width. Thus, the conventional support rack is not available for articles of different sizes and specifications.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 2-4, a support rack in accordance with the preferred embodiment of the present invention comprises a base 2, two supporting units 3, a first positioning member 4, a clamping member 5, and a second positioning member 6.

The base 2 includes a back cover 21. The back cover 21 has a cover body 211 for mounting the first positioning member 4, and a brake member 212 arranged on the cover body 211. The brake member 212 is a elastic plate and has a connecting end 213 connected with the cover body 211 and a braking end 214 located opposite to the connecting end 213.

Each of the supporting units 3 includes a support seat 31, a resting member 32, and a toothed member 33.

The support seat 31 of each of the supporting units 3 is pivotally connected with the base 2 and extends downward in an inclined manner. The support seat 31 of each of the supporting units 3 includes a pivot end 311 pivotally connected with the base 2, a mounting portion 312 located opposite to the pivot end 311, an arcuate stepped slot 313 formed in the mounting portion 312, and a pivoting hole 314 formed in the mounting portion 312.

The resting member 32 of each of the supporting units 3 is mounted on the mounting portion 312 of the support seat 31 and includes a holder 321, a limit rod 322 formed on the holder 321 and slidably mounted in the stepped slot 313, and a pivot shaft 323 formed on the holder 321 and pivotally mounted in the pivoting hole 314.

When the holder 321 of the resting member 32 of each of the supporting units 3 is pivoted relative to the support seat 31, the pivot shaft 323 is pivoted in the pivoting hole 314, and the limit rod 322 slides in the stepped slot 313, so that the resting member 32 of each of the supporting units 3 is rotated relative to the support seat 31 to freely adjust the angle of the resting member 32 relative to the support seat 31.

The toothed member 33 of each of the supporting units 3 has an arcuate profile and is mounted on the support seat 31. The toothed members 33 of the supporting units 3 mesh with each other along arcuate tangent lines. The toothed member 33 of each of the supporting units 3 has a toothed face 331 (see FIG. 5), and the braking end 214 of the brake member 212 of the back cover 21 abuts the toothed face 331 of the toothed member 33 of each of the supporting units 3.

The toothed face 331 of the toothed member 33 of each of the supporting units 3 has a plurality of anti-skid grooves 332 to enhance the friction between the braking end 214 of the brake member 212 of the back cover 21 and the toothed face 331 of the toothed member 33 of each of the supporting units 3.

The first positioning member 4 includes a pivot portion 41 pivotally . connected with the cover body 211 of the back cover 21, a protruding block 42 extending from the pivot portion 41 and abutting the braking end 214 of the brake member 212 of the back cover 21, and a handle 43 extending from the pivot portion 41 and located opposite to the protruding block 42.

Referring to FIGS. 4-6, the first positioning member 4 is rotatable relative to the back cover 21 between a locked position and an unlocked position.

As shown in FIGS. 4 and 5, when the first positioning member 4 is disposed at the locked position, the handle 43 of the first positioning member 4 is adjacent to the back cover 21, the protruding block 42 of the first positioning member 4 abuts the braking end 214 of the brake member 212 of the back cover 21, and the braking end 214 of the brake member 212 of the back cover 21 engages the toothed face 331 of the toothed member 33 of each of the supporting units 3, and is inserted into and locked in one of the anti-skid grooves 332 (see FIG. 9) of the toothed face 331. Thus, the supporting units 3 are locked onto the base 2 by the first positioning member 4 to fix the angle between the support seats 31 and the distance between the resting members 32.

As shown in FIGS. 6 and 7, when the first positioning member 4 is disposed at the unlocked position, the handle 43 of the first positioning member 4 is spaced from the back cover 21, the protruding block 42 of the first positioning member 4 is detached from the braking end 214 of the brake member 212 of the back cover 21, and the braking end 214 of the brake member 212 of the back cover 21 disengages the toothed face 331 of the toothed member 33 of each of the supporting units 3, so that the supporting units 3 are unlocked from the base 2. Thus, the support seats 31 of the supporting units 3 are pivoted synchronously relative to the base 2 by intermeshing of the toothed members 33 to adjust the angle between the support seats 31 and the distance between the resting members 32.

The clamping member 5 is retractably mounted on the base 2 and extends upward from the base 2. The clamping member 5 is movable relative to the base 2 as shown in FIG. 7 to adjust the distance between the clamping member 5 and the base 2.

The second positioning member 6 is mounted on the base 2 to position the clamping member 5 on the base 2. The second positioning member 6 has a structure and an operational manner similar to that of the first positioning member 4, and will not be further described in detail.

In operation, referring to FIGS. 7 and 8 with reference to FIGS. 5 and 6, the first positioning member 4 and the second positioning member 6 are respectively adjusted to the unlocked position, so that the support seats 31 of the supporting units 3 are pivotable relative to the base 2, and the clamping member 5 is movable relative to the base 2. Then, the support seats 31 of the supporting units 3 are pivoted relative to the base 2 to adjust the angle between the support seats 31 and the distance between the resting members 32, and the resting members 32 are rotated relative to the support seats 31 to adjust the angle of the resting members 32. Then, an article, such as a tablet computer 7, a book, a music score or the like, is placed on the supporting units 3. Then, the first positioning member 4 is adjusted to the locked position (see FIG. 9), so that the supporting units 3 are locked onto the base 2. Then, the clamping member 5 is pressed and moved downward to clamp the tablet computer 7. Then, the second positioning member 6 is adjusted to the locked position, so that the clamping member 5 is locked onto the base 2. Thus, the tablet computer 7 is placed on and supported by the support rack solidly and stably, thereby facilitating a user operating the tablet computer 7.

Referring to FIGS. 7 and 8, the distance between the supporting units 3 is adjusted by adjusting the opening angle of the support seats 31 and by adjusting the angles of the resting members 32, so that the width of the support rack can be adjusted. In addition, the clamping member 5 is movable relative to the base 2 to adjust the length the support rack. Thus, the width and the length of the support rack can be adjusted freely so that the support rack is available for articles of different sizes and specifications.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
