## Background
BACKGROUND OF THE INVENTION
The present invention relates to a fixing member, especially to a fixing member for handheld electronics.
There are various types of handheld electronics such as PDA (Personal Digital Assistant), GPS (Global Position System) and mobile phones etc. For convenience of using handheld electronics in vehicles, a fixing member for handheld electronics is set inside the vehicles. There are various designs of fixing member for handheld electronics available on the market now. Most common one is hook-and-lock type or clip type. However, both have its disadvantages.
The hook-and-lock type fixing member requires precise location. After being used for a period of time, the device may have wear and tear. Thus the hook and the lock may slip from each other. Therefore, the handheld electronic is unable to be fixed by the hook-and-lock. As to the clip-type, a gear set is used for clipping. Such design is not only complicated but also easy to get damages. The device is inconvenient for use.
Thus there is a need to develop a fixing member for handheld electronics with features of simple structure, holding the handheld electronic tightly and convenience of use for overcoming above shortages.

It is another object of the present invention to provide a fixing member for handheld electronics that includes an elastic arm disposed on the side wall of the slot and the one-way rolling member is disposed on the elastic arm. Thus by the elastic arm, the one-way rolling member has elasticity for clipping so that the handheld electronic is mounted in the slot more firmly.
In order to achieve objects, the fixing member for handheld electronics according to the present invention consists of a fixing seat, a rotation axis and at least one-way rolling member. The fixing seat is disposed with a slot and the rotation axis is set on the fixing seat. The one-way rolling member is pivoted in the fixing seat by the rotation axis and part of the one-way rolling member exposes on inner surface of the slot. Thus the side wall of the handheld electronic leans against the one-way rolling member when the handheld electronic is set in the slot. Therefore, the handheld electronic is set in the slot more easily and firmly without falling off from the slot.
Moreover, the present invention further includes an elastic arm that is set on a side wall of the slot. The rotation axis is disposed on the elastic arm. Thus the side wall of the handheld electronic leans against the one-way rolling member when the handheld electronic is set in the slot. Therefore, the handheld electronic is set in the slot more easily and firmly without falling off from the slot.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Refer from FIG. 1A to FIG. 1C, a fixing member of handheld electronics 10 according to the present invention consists of a fixing seat 20, a rotation axis 32 and at least one one-way rolling member 40. The fixing seat 20 is mounted with a slot 22 and the rotation axis 32 is disposed on the fixing seat 20. A stopping member 322 is set on one side of the rotation axis 32 while the one-way rolling member 40 is pivoted in the fixing seat 20 by the rotation axis 32 and part of the one-way rolling member 40 exposes outside (out of) a slot 22. The stopping member 322 leans against a side wall of the one-way rolling member 40.
The one-way rolling member 40 includes a ratchet or a one-way bearing. In this embodiment, the ratchet is used. A plurality of serrated grooves 402 is set inside the one-way rolling member 40. When the one-way rolling member 40 is assembled on the rotation axis 32, the stopping member 322 leans against one of the serrated grooves 402. As shown in figure, the slopes of two sides of the serrated groove 402 are different. One side thereof has larger slope so that resistance between this side and the stopping member 322 is smaller. Thus the one-way rolling member 40 gets easier to roll in one direction, compared with the reverse direction. The rolling member 40 may even stop in the reverse direction. In this embodiment, the one-way rolling member 40 tends to roll toward the slot 22 while gets difficult in the reverse direction. Thus when a handheld electronic 10 is set in the slot 22, the side wall of the handheld electronic 10 leans against the one-way rolling member 40 so that the handheld electronic 10 is slipped into the slot 22 smoothly. Therefore, the handheld electronic 10 is easily set into the slot 22 and is difficult to fall off from the slot 22.
If the one-way rolling member 40 is a one-way bearing, the one-way bearing rolls around the rotation axis 32 in a single direction when the one-way bearing is disposed on the rotation axis 32. Thus there is no need to dispose the stopping member 322 on the rotation axis 32 for enabling the one-way rolling member 40 rolling in a single direction. Moreover, the side wall of the one-way rolling member 40 is made of elastic material or material having larger friction (resistance). The elastic material includes rubber. When the handheld electronic 10 is set in the slot 22, the side wall of the one-way rolling member 40 leans against the handheld electronic 10 and the handheld electronic 10 is clipped firmly by the elasticity of the side wall of the one-way rolling member 40.
Refer to FIG. 2A & FIG. 2B, another embodiment is disclosed. This embodiment further includes an elastic arm 34 that is disposed on a side wall of the slot 22 and a rotation axis 32 is set on the elastic arm 34. By the elastic arm 34, the one-way rolling member 40 has elasticity for clipping so that the handheld electronic 10 is mounted in the slot 22 more stably. Furthermore, the size of the handheld electronic 10 may vary and the preset distance for clipping between the one-way rolling member 40 and the handheld electronic 10 also changes. Thus by the elastic arm 34, the handheld electronic 10 is clipped more firmly by the one-way rolling member 40. Moreover, the elastic arm 34 is disposed with a bending part 342 so that the elastic arm 34 is more flexible.
Refer to FIG. 3, a further embodiment is disclosed. The difference between this embodiment and above one is in that this embodiment further includes a rolling member 50 and a conveyor belt 60. The rolling member 50 is pivoted inside the fixing seat 20 and a part thereof exposes on inner surface of the slot 22. The rolling member 50 is on the same side of the one-way rolling member 40 and the conveyor belt 60 is putted around the one-way rolling member 40 and the rolling member 50. The rolling member 50 is an idler wheel and the conveyor belt 60 is made of rubber. When the handheld electronic 10 is set in the slot 22, the conveyor belt 60 leans against the side wall of the handheld electronic 10. The one-way rolling member 40 in combination with the rolling member 50 drives the conveyor belt 60 to move forward and backward and attach on side wall of the handheld electronic 10 so as to hold the handheld electronic 10 inside the slot 22. The contact area is increased by the conveyor belt 60 and the friction force is also increased. Therefore, the handheld electronic 10 is mounted more stably.
In summary, a fixing member for handheld electronics according to the present invention includes a fixing seat, a rotation axis and at least one one-way rolling member. The fixing seat is disposed with a slot and the rotation axis is set on the fixing seat. The one-way rolling member is pivoted in the fixing seat and part of the on-way rolling member exposes on the surface of the slot while the one-way rolling member is set on the rotation axis. Thus a side wall of the handheld electronic leans against the one-way rolling member when a handheld electronic is set inside the slot. Therefore, the handheld electronic is mounted inside the slot easily and stably without falling off.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
