Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted stand for fixing a small electronic device such as a PDA (personal digital assistant).

[0002]

2. Description of the Related Art For example, in a conventional vehicle-mounted small electronic equipment stand shown in FIG. 10, a holder 22 for holding a PDA or the like has two hinges A and B orthogonal to each other with respect to a base 21 fixed to a vehicle body. It is connected via three connecting members 23, 24, 25. The hinge A has a rotation axis parallel to the Y axis and is rotatable in the X axis direction, and the hinge B has a rotation axis parallel to the X axis and is rotatable in the Y axis direction.
Through the two hinges A and B, the holder 22 rotates in two directions of an X-axis direction (front and rear) and a Y-axis direction (left and right) with respect to a base 21 fixed to a vehicle dashboard or the like. It is possible to adjust the angle. In addition, due to the elastic force provided in the hinge shafts of the hinges A and B, the circular hinge shaft heads a and b respectively have tightened the coupling members 24 and 25 serving as bearings, and the hinge shafts A and B
The rotation of B is fixed.

[0003]

However, in the above-described vehicle-mounted stand, as shown in FIG. 10, the rotation direction of the holder is X.
Only in two directions orthogonal to the axis and the Y-axis, and as shown in FIG. 11, the "elevation angle of the holder central axis (the tilt angle in the vertical direction with respect to the base)" can be adjusted by rotation on the X-axis. As shown in, the center axis O of the holder is tilted to the left and right due to the rotation in the Y-axis direction, and the display on the display is also slanted, which makes it difficult to use. It is impossible to adjust the “direction θ in FIG. 10)”.

An object of the present invention is to adjust the elevation angle of the central axis of the holder, the rotation angle with respect to the central axis, and both angles, and to prevent the central axis of the holder from tilting in the left-right direction.

[0005]

In order to solve the above problems, the present invention is directed to a base fixed to a vehicle body, a holder for supporting a small electronic device, and an intermediate member interposed between the base and the holder. The base and the intermediate member, and the holder and the intermediate member are connected to each other in a pressure contact state with elastic force, and a support shaft is passed through the pressure contact surface to be rotatable about the axis. A pair of friction plates are formed on each pressure contact surface so that the friction surfaces face each other, and the pair of friction surfaces between the base and the intermediate member can adjust the lateral angle of the degree of rotation of the holder,
The pair of friction surfaces between the holder and the intermediate member can adjust the elevation angle of the undulation degree of the holder.

When this stand is used, the holder is gripped by hand and the pair of friction plates are slid and rotated about the axes of the two support shafts. Thereby, the elevation angle of the central axis of the holder, the rotation angle with respect to the central axis, and both angles can be adjusted. Further, at this time, since the pair of friction surfaces slide, the stationary state can be maintained at the arbitrary adjustment position.

Although the above-mentioned means uses two support shafts, it is also possible to adopt a means in which one support shaft is used to concentrate the movable parts at one place. The means for using only one support shaft includes a base fixed to the vehicle body, a holder for supporting the small electronic device, and an intermediate member interposed between the base and the holder. After the support shaft has penetrated the intermediate member, the holder is penetrated through the elongated hole, and a fastener is provided at the tip of the support shaft so that the intermediate member can rotate around the support shaft with respect to the base. The holders are elastically connected to each other via the elongated holes so that they can be undulated and connected in a pressed state. Next, friction surfaces are formed to face each other between the base and the intermediate member and between the holder and the intermediate member, and the former pair of friction surfaces can adjust the lateral angle of the degree of rotation of the holder. The pair of friction surfaces are arc surfaces, and the latter pair of friction surfaces are arc surfaces capable of adjusting the elevation angle of the undulation degree of the holder.

By this means, the elevation angle of the central axis of the holder, the rotation angle with respect to the central axis, and both angles can be adjusted, and the stationary state can be maintained at any of the adjusted positions. At this time, since there is only one support shaft, the movable parts can be concentrated at one place, and it is not necessary to change the holder when adjusting by applying force in each direction, and the operation is easy.

Further, as another means of using one support shaft,
In the above structure, a structure in which the holder is provided with the support shaft may be adopted. In this means, the support shaft provided in the holder is passed through the intermediate member, and then is passed through the base through the elongated hole, and a fastening tool is provided at the tip of the support shaft. At this time, the holder is rotatable with respect to the base around the support shaft, and the intermediate member is elastically connected to the base member via the elongated hole in a pressure contact state so that the intermediate member is connected between the base and the intermediate member. , And between the holder and the intermediate member,
If the friction surfaces face each other, the elevation angle of the central axis of the holder, the rotation angle with respect to the central axis, and both angles can be adjusted, and the stationary state can be maintained at any of the adjusted positions.

[0010] In the means for making these support shafts one,
A configuration in which the intermediate member is composed of two plates can also be adopted. Friction surfaces are formed so as to face each other between the two intermediate members, and the pair of friction surfaces are arcuate surfaces capable of adjusting the lateral angle of the degree of rotation of the holder, and the one intermediate member. It is also possible to adopt a configuration in which the pair of friction surfaces, which form arcuate surfaces for adjusting the elevation angle of the holder, are formed between the bases and between the other intermediate member and the holder, respectively. In this configuration, since the elevation angle adjusting portions are provided on both sides of the intermediate member, the adjustment angle can be made large.

Although various types of friction plates such as friction plates can be adopted as the above-mentioned friction surfaces, if the teeth orthogonal to the rotation and movement directions are arranged, the friction between the friction surfaces due to the meshing of the teeth. The force is strengthened and the stationary fixation in the stationary state becomes stable.

Further, it is possible to form the friction surface of the base and the holder on a protrusion bulged from the base and the holder. As a result, a wide space for adjusting the elevation angle of the holder can be secured. The protrusion of this holder can be detached from the holder and removable, and at this time, if you slide the protrusion on the back of the holder and detachably fit, it is convenient to remove only the holder at the time of use, It is also compact when stored. Further, if the holder and the protrusion are rotatably coupled by a well-known universal joint or the like, the holder can be tilted left and right (in the β direction in FIG. 12), and the supported small electronic device can be tilted at an arbitrary angle. It's convenient.

As a means for connecting the base, the holder and the intermediate member in a pressed state with elastic force, for example, a compressed spring is provided between the support shaft and the base or the holder, and more specifically, the support shaft. When a compressed spring is fitted to fix the tightening tool, an extension force acts between the support shaft and the holder or the base, and the base, the holder and the intermediate member are elastically connected to each other in a pressed state. Further, even if an elastic material such as rubber is fitted to the support shaft instead of the spring and fixed with a tightening tool, the base, the holder and the intermediate member are connected in a pressed state with elastic force.
