Description

  The present invention relates to a support frame suitable for use in a small and portable electronic device such as a mobile phone, an electronic book reader, or a tablet personal computer.

  Due to factors such as digitization, technological maturity, and price reduction, the electronic devices described above have already become one of daily necessities for people. However, in order to keep the electronic device as thin and light as possible and to reduce its outer shape, support means are often not provided for holding it in place during use. For this reason, it is difficult for such an electronic device to be stably placed on a desk in an easy-to-see state for a user to view an electronic document or a video. Accordingly, there is an increasing demand for a support frame that can be used in accordance with the electronic device as needed to meet the need for not having to hold it when viewing the electronic device.

  As described above, usually, the support frame for standing the electronic device on the desk is usually divided into two types, that is, a type in which the tilt angle is fixed, or a type in which the tilt angle is adjustable. The former is relatively inconvenient because the support frame can only be fixed at a specific angle and the angle cannot be adjusted according to the needs of the user. On the other hand, in the latter, the angle of the support frame is adjusted with a structure in which a plurality of position limiting slots and gears are combined. However, since the structure of such a design is relatively complicated and does not have a self-locking function, there is a problem that the stability is relatively poor.

  Therefore, how to provide a support frame having a simple structure and having a self-locking function is one of the problems that must be solved quickly in this technical field.

  In view of the above problems, an object of the present invention is to provide a support frame suitable for use in a small and portable electronic device having a simple structure and a self-locking function.

  The present invention provides a support frame 1 that is used when the electronic device 2 is used. The support frame 1 of this embodiment includes a main body 10, a support member 12, and a positioning shaft 14.

  The main body 10 has an accommodation space 102 and the electronic device 2 is installed in the accommodation space 102. Therefore, the accommodation space 102 is designed according to the outer shape of the electronic device 2. The electronic device 2 used in the present embodiment is, for example, a mobile phone, an electronic book reader, or a tablet personal computer. In this embodiment, a tablet personal computer is taken as an example, but the present invention is not limited to this.

  The support member 12 is installed on the side of the main body 10. Further, the support member 12 of the present embodiment can be rotated with respect to the main body 10 and is installed on the opposite side to the accommodation space 102. Further, by rotating the support member 12, the electronic device 2 can be placed upright at various different angles.

  In addition, the support member 12 of this embodiment further includes a handle portion 122. The purpose of installing the handle portion 122 is that when the user does not need to place the electronic device 2 on the desk, the user can rotate the support member 12 to a state parallel to the main body 10 (stored state). The electronic device 2 can be carried directly by the handle portion 122 without the need for the device.

  Refer now specifically to FIG. The support member 12 has a through hole 124 (see FIG. 2). The through hole 124 includes a positioning section 124A and a rotating section 124B (see particularly FIG. 4), and the inner diameter of the rotating section 124B is larger than the inner diameter of the positioning section 124A.

  The positioning shaft 14 (FIGS. 1 to 3) is installed in the through hole 124 (FIG. 2) of the support member 12 so as to be movable in the axial direction, and at the same time, the positioning shaft 14 includes a pressing portion 142 and a fitting portion 144. The pressing part 142 is connected to the fitting part 144. Further, the positioning shaft 14 has a function of supporting the support member 12 so that the support member 12 can be selectively rotated with respect to the main body 10. That is, the support member 12 is held so as to be rotatable with respect to the main body 10 with the positioning shaft 14 as an axis.

  More specifically, the outer shape (outer peripheral shape) of the fitting portion 144 of the positioning shaft 14 of this embodiment matches the inner shape (inner peripheral shape) of the positioning section 124A of the through hole 124. More preferably, the outer shape of the fitting portion 144 of the present embodiment has the same shape and size as the inner shape of the positioning section 124A of the through hole 124.

  What should be replenished here is that “the same shape” and “the same size” as used herein mean that at least a part of the outer shape (outer peripheral shape) of the fitting portion 144 is the position of the positioning section 124A of the through hole 124. It is possible to engage with the inner shape (the shape of the inner periphery), that is, the positioning shaft 14 and the support member 12 have a shape and size that can be engaged with each other so that they cannot rotate with respect to each other about the axis. pointing. For example, if the inner shape of the positioning section 124A of the through hole 124 is a hexagonal hole and the outer shape of the fitting portion 144 is a triangular prism or a hexagonal prism, each column angle of the fitting 144 is the same as that of the support member 12. It can be engaged with a plurality of holes of the through hole 124. Therefore, the hexagonal hole-shaped positioning section 124A and the triangular or hexagonal column-shaped fitting portion 144 are referred to as having the “same shape” and “same size”. Further, by designing the shape of the fitting portion 144 to be a special equiangular column, the user can easily determine the magnitude of the rotation angle of the support member 12.

  In this embodiment, the support frame 1 further includes an elastic member 18, and the elastic member 18 is installed and positioned so that at least one end thereof extends into the through hole 124 (FIG. 2) of the support member 12. The fitting part 144 of the shaft 14 is brought into contact with the fitting part 144. The elastic member 18 is a coil spring or a spring plate as shown.

  The support frame 1 of this embodiment further includes a pivot member 16, and the pivot member 16 is installed between the main body 10 and the support member 12. That is, the support member 12 of this embodiment is connected to the main body 10 via the pivot member 16 so as to be rotatable.

  In this embodiment, a U-shaped pivot member 16 is taken as an example. The pivot member 16 includes pivot holes 162a and 162b (FIG. 2). The pivot holes 162a and 162b are formed on both arms of the U-shaped structure of the pivot member 16, respectively. The pivot holes 162a and 162b are installed so as to be coaxial with the through hole 124 of the support member 12, and at the same time, the positioning shaft 14 is installed through the pivot holes 162a and 162b (in this embodiment, The positioning shaft 14 can be inserted through the pivot hole 162b, the through hole 124, and the pivot hole 162a in this order). Furthermore, the diameter of the pivot hole 162a is designed to be slightly smaller than the fitting portion 144 of the positioning shaft 14, and the shape and size of the pivot hole 162a are designed to be the same as the pressing portion 142 of the positioning shaft 14. The positioning shaft 14 can be held so as not to rotate with respect to the pivot member 16 and the main body 10, and the rotational angle position of the support member 12 can be positioned.

  The pivot member 16 can be used for guiding or preventing erroneous operation, in addition to having the fixing action of the support member 12 via the positioning shaft 14. On the other hand, by further restricting, an unreasonable operation or an erroneous operation can be prevented and the life of the support frame 1 can be extended.

  Next, please refer to FIGS. 4 and 5 simultaneously. When the positioning shaft 14 inserted through the through hole 124 (FIG. 2) of the support member 12 is in the first position as shown in FIG. 4, the fitting portion 144 of the positioning shaft 14 is engaged with the positioning section 124A of the through hole 124. Match. The size of the external shape (substantially star shape in this embodiment) of the fitting portion 144 of this embodiment is the same as the size of the inner shape (substantially star shape in this embodiment) of the positioning section 124A of the through hole 124. When the shaft 14 is in the first position as shown in FIG. 4, the support member 12 is locked with respect to the main body 10 and cannot rotate.

  On the other hand, when the positioning shaft 14 is pushed into the through hole 124 and is in the second position as shown in FIG. 5, the fitting part 144 moves to the rotating section 124B of the through hole 124 and at the same time, the elastic member 18 moves to the fitting part. Compressed and deformed by being pressed by 144. At this time, since the diameter of the inner shape (circular as shown in FIG. 2 in this embodiment) of the rotating section 124B is slightly larger than the maximum diameter of the outer shape (substantially star shape) of the fitting portion 144, the positioning shaft 14 is supported. Without being engaged with the member 12, the support member 12 can rotate with respect to the main body 10, and the angle between the two is adjustable.

  In this embodiment, the positioning shaft 14 is moved by the user directly or indirectly pressing the pressing portion 142 of the positioning shaft 14 to move the fitting portion 144 from the positioning section 124A of the support member 12 toward the rotating section 124B. It can be made to. When the user stops pressing the pressing portion 142, the elastic member 18 moves and returns the fitting portion 144 of the positioning shaft 14 to the positioning section 124A side by its elastic restoring force. This achieves a self-locking function that automatically returns to the locked state.

  In short, when the pressing portion 142 is in the second position as shown in FIG. 5, the elastic member 18 presses the fitting portion 144 by its elastic restoring force, thereby moving the fitting portion 144 toward the positioning section 124A. Thus, the pressing portion 142 is moved to the first position as shown in FIG. The pressing direction of the elastic restoring force provided by the elastic member 18 is indicated by a white arrow in FIG.

  In other examples, it can also constitute so that press part 142 may be pushed via members, such as a lever, and is not limited to the method concerning this example.

  To summarize the above, the present invention has a simple structure by configuring the support frame to be switched between a locked state and a state in which the angle can be adjusted by installing the positioning shaft at different positions. A support frame having a self-locking function can be provided.

  The above examples are illustrative and not intended to limit the present invention. Any equivalent modifications or changes made without departing from the spirit and scope of the present invention are included in the appended claims.

  With the above configuration, the present invention can provide a support frame that is simple in structure and has a self-locking function.
