SUPPORTING RACK WITH ADJUSTABLE TORSION
A supporting rack for supporting an electronic device includes a main body, a rotating arm, a fastening member and a position portion. The main body includes a connecting portion and a plurality of holding members. The connecting portion is connected with the electronic device, the holding members are disposed on the connecting portion, and each of which includes a first surface and a second surface opposite thereto. A gap is formed between adjacent holding members. The rotating arm, held by the holding members, tightly contacts the first surface. The fastening member connects with the holding members between a first position and a second position. The position portion is disposed on the holding member. When the fastening member is connected with the holding members at the first position, an interference, formed between the fastening members and the second surface, is increased as the fastening member is moved toward the second position.

BACKGROUND OF THE INVENTION1. Field of the Invention
The invention relates to a supporting rack, and in particular, to a supporting rack with adjustable torsion.
2. Description of the Related Art
Referring to
A pressing portion C is formed at a contacting interface between the top portion of the fastening member 13 and the holding members 112. During the screwing fastening member 13 with the screwing portion 113, the fastening member 13 applies a force to the holding members 112 via the pressing portion C causing upper portions of the holding members 112 to be pressed toward the center (i.e. toward the spherical body 122), thus increase the torsion between the holding members 112 and spherical body 122.
BRIEF SUMMARY OF THE INVENTIONA supporting rack with adjustable torsion is provided for supporting an electronic device including a main body, a rotating arm, a fastening member and a position portion. The main body includes a connecting portion and a plurality of holding members. The connecting portion is connected with the electronic device, the holding members are disposed on the connecting portion, and each of the holding members includes a first surface and a second surface opposite to the first surface. A gap is formed between adjacent holding members. The rotating arm, held by the holding members, tightly contacts the first surface. The fastening member is connected with the holding members between a first position and a second position. The position portion is disposed on the holding member. When the fastening member is connected with the holding members at the first position, an interference is formed between the fastening members and the second surface. The interference is increased as the fastening member is moved toward the second position.
A detailed description is given in the following embodiments with reference to the accompanying drawings.
The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
As shown in
Referring to
The rotating arm 200 comprises a rotating bar 201 and a spherical body 202. The spherical body 202, connected with the rotating bar 201, is disposed and clamped between the holding members 1021 of the holding portion 102, such that an outer surface 202S of the spherical body 202 tightly contacts the first surfaces S1 of each holding members 1021. With rotation of the spherical body 202 in the holding portion 102, the rotating arm 200 is moved relative to the connecting portion 101 accordingly, thus the electronic device could be adjusted to a desired position relative to the user's position.
It should be noted that a gap G is formed between every two adjacent holding members 1021. With aid of the elastic characteristics of the materials used, required elasticity of the holding portion 201 could be obtained and interference between the holding members 1021 and the outer surface 202S of the spherical body 202 could be changed by adjusting the width of the gap G to control the holding strength (or the torsion) of the holding portion 201.
Referring to
In the embodiment, the fastening member 300 is directly screwed to the holding portion 102, which allows the force applied to the second surface S2 of the holding portion 102 by the fastening member 300 is gradually increased. That is, the user may adjust the interference CS between the first surface S1 and the spherical body 202 for a desired torsion therebetween. Moreover, the holding strength (or the torsion) of the fastening member 300 may be evenly distributed to the holding portion 102.
Referring to
Additionally, the position protrusions 401 can also be disposed on the multiple holding members 1021, respectively. It is not limited to arrange all the position protrusions 401 on a single holding member 1021, and it is not limited to have only one notch 301. The disposition of the position protrusions 401 and the notch 301 allows the fastening member 300 to be fixed with multiple stages according to needs. For such reason, the number of the position protrusions 401 and the notch 301 is not specific.
The supporting rack 1 of the invention utilizes the direct screwing between the fastening member 300 and the holding portion 102 to adjust the torsion of the rotating arm 200. In addition, with arrangement of the position portion 400 and the notch 301, the fastening member 300 is able to be fixed at a specific position, where also provide a fixed corresponding torsion of the rotating arm 200.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
