Abstract

PROBLEM TO BE SOLVED: To facilitate the regulation of the position and the angle of elevation of an electronic apparatus, in a support device for an on-mounting electronic apparatus. SOLUTION: When a fastening member 16 is fastened, a moving member 12 is fixed at a strut 11, and vertical movement of the moving member 12 and rotation around the strut 11 is checked. Since an engaging member 13, simultaneously, presses a regulation mechanism 14, rotation around an arbor 16a is also checked. Thus, only by fastening a fastening member 16, the position and the angle of elevation of an electronic apparatus mounted on a holding member 20 are fixed. In this case, the protrusions (a) and (b) protruding from an engaging member 13 are fitted in the recessed parts 14b of the uneven surface 14B of a regulation mechanism 14, protrusions (c) and (d) make contact with protrusion parts 14a. Reversely, when the protrusions (a) and (b) make contact with the protrusion parts 14a, the other protrusions (c) and (d) are fitted in recessed parts 14a. This constitution finely sets the angle of elevation.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supporting an electronic device such as an on-vehicle monitor, and more particularly to a device for fixing an electronic device at an appropriate position or for easily releasing the device and improving the accuracy of elevation angle adjustment. The present invention relates to a support device for electronic equipment.

[0002]

2. Description of the Related Art As an on-vehicle monitor, there is a monitor which is stored in a horizontal position in a housing like a cassette, a CD or an MD player, and is stored in a dashboard or the like. Then, the monitor is discharged from the housing by a loading mechanism or the like, and thereafter, is raised to a vertical standing posture and used. However, since the size of this type of in-vehicle monitor is a standard size such as 1 DIN, there is a limit to the size of the monitor housed in the case. Impossible.

[0003] On the other hand, recently, in-vehicle navigation is remarkably widespread, and in many cases, a monitor housed in the housing is used as a monitor for navigation. However, it has been pointed out that the monitor having a small size is extremely difficult to view because the map and character information to be projected are necessarily small.

[0004] In order to cope with such an indication, for example, there is a means for displaying a part of a screen by zooming up. However, it is necessary to switch between the normal screen and the zoomed-up screen, and it is necessary to select a portion for which zoom-up is desired from the entire map, and it is troublesome to always perform the operation. When the screen is switched to the normal screen, it is necessary to search for the position such as the current position or the destination again. In order to solve such a problem, it is optimal to increase the size of the monitor and display the characters and the like on the screen as large as possible. Therefore, a wide monitor is used.

[0005]

However, a problem here is the support mechanism for mounting the wide monitor in the vehicle. This is because when a wide monitor is used for navigation, a wide monitor which is normally used in a horizontal screen state is used to display a map to a destination in a wider area.
It may be used as a vertical screen rotated by degrees. Therefore, it is necessary not only to simply support the wide monitor, but also to provide a means for alternately switching between the horizontal screen and the vertical screen. At this time, it is essential that the screen can be easily switched between the horizontal screen and the vertical screen, and that the screen is stably supported in any of the supported states.

In view of the ease of viewing and handling, the support device allows the monitor to be fixed in various positions, that is, the height direction, the left-right direction, and the elevation angle can be adjusted, and the support device can be easily set to a desired position. Is desired. Also,
Since a large screen wide monitor is heavier than a normal monitor, a so-called “bow” phenomenon in which the screen of the monitor tilts downward easily occurs. Therefore, the elevation angle must be able to be reliably fixed. At the same time, it is preferable that the elevation angle can be adjusted more finely.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an electronic device supporting apparatus capable of fixing an electronic device supported by a column or the like to an arbitrary position and releasing the electronic device. The purpose is.

It is another object of the present invention to provide a support device capable of adjusting a vertical direction, a left-right direction, an elevation angle, and the like, and more particularly, to a support device for an electronic device capable of more precisely adjusting the elevation angle. .

[0009]

According to a first aspect of the present invention, there is provided a supporting apparatus for an electronic apparatus, the apparatus being movable in an axial direction of a first axis supported by a portion to be installed and rotatable about the first axis. And a holding member rotatably provided around a second axis perpendicular to the first axis with respect to the moving member, and the holding member includes an electronic device. Is held.

In the present invention, a moving member is provided on the first shaft (post), and a second shaft (mandrel) is provided on the moving member perpendicular to the first shaft. In the first shaft, the moving member is moved in the axial direction of the first shaft and is rotatable around the first shaft, so that the vertical and horizontal swing angles can be adjusted. The second axis is rotatable around this axis, so that the elevation angle can be adjusted.

In the above, one of the moving member and the holding member has an adjusting mechanism having an uneven surface provided at predetermined intervals around an axis of the second shaft, and the other has an adjusting mechanism fitted on the uneven surface. It is preferable that an engaging member having a projection that abuts or abuts is provided.

That is, the present invention includes a case in which the holding member is provided with the adjusting mechanism, and a case in which the moving member is provided with the engaging member, and conversely, a case in which the holding member is provided with the engaging member. Includes those in which an adjustment mechanism is provided on the moving member.

When one of the plurality of projections provided on the engagement member is fitted into the concave portion of the concave and convex surface of the adjusting mechanism, the other projections are arranged so as to come into contact with the convex portion. A fixed position is preferred.

In this case, when the elevation angle of the electronic device is adjusted, the holding member is rotated about the second axis. At this time, it is necessary to make sure that the projection of the engaging member is fitted to the concave portion and the convex portion of the uneven surface. Or it will be in contact. Therefore, when the holding member side (electronic device side) is rotated, the fitting or contact between the uneven surface and the projection can be repeated every half pitch of the unevenness, so that the elevation angle can be more finely adjusted. is there.

Further, the moving member is moved to the first position by the second shaft.
It is preferable to provide a fastening means for fastening the moving member and the holding member together by tightening the holding member against the moving member and pressing the holding member against the moving member.

That is, as shown in FIG.
a, the width of the gap between the holding portion 12b and the holding portion 12c is reduced.
Fixed to Therefore, the vertical movement of the moving member 12 and the left and right swing angles can be fixed at once. At the same time, the holding member 20 is pressed against the moving member 12 via the engaging member 13 and the adjusting mechanism 14. Therefore, the elevation angle of the holding member 20 can be fixed. That is, by tightening the second shaft 16a, the vertical and horizontal swinging of the moving member 12 and the elevation angle of the holding member 20 can be fixed at a time, so that the position of the electronic device held by the supporting device can be fixed. Further, the adjustment of the posture can be facilitated.

And abuts on the projection 14a. Therefore, when the holding member 20 is adjusted (elevation angle adjustment) around the second axis (mandrel 16a) as described later, the projections a, b, c, and d repeatedly fit into the recess 14b. A moderate click feeling can be obtained.

A pressing member 15 having an insertion hole 15a formed in the center is interposed between the engaging member 13 and the adjusting mechanism 14. The pressing member 15 has both end surfaces in contact with the periphery of the insertion hole 13 a of the engagement member 13 and the periphery of the screw receiving portion 14 a of the adjustment mechanism 14. The pressing member 15 is provided with pressing portions 13A, 13B, 1 of the engaging member 13.
It has a function of bringing 3C and 13D into contact with the uneven surface 14B in an appropriate state.

As described above, the adjustment mechanism 14 is attached to the holding member 20. The holding member 20 has, for example, a shape as shown in FIG. 1, and an outer cylindrical portion 20A integrally formed with a connecting portion indicated by reference numeral 20a, and a 90 ° angle in the α1 direction or α2 direction with respect to the outer cylindrical portion 20A. The rotating unit 21 is configured to rotate within the range, and a fixed member 18 and a pressing member 19 provided at the tip of the rotating unit 21 on the Y2 side which is narrowed down finely.

The other side (X2 side) of the outer cylindrical portion 20A
, A lock lever 22 is rotatably supported in the illustrated β1 direction or β2 direction. For example, when the lock lever 22 is tilted in the β1 direction as shown in FIG. 1, the lock state is established, and the rotation of the rotating unit 21 is stopped. On the contrary, when the lock lever 22 is tilted in the β2 direction, it is in the unlocked state, and the rotating part 21 can freely rotate in the α1 or α2 direction within a range of 90 degrees.

A screw hole (not shown) is formed in the Y2 side end face of the rotating portion 21, and the fixing member 18 is fixedly screwed to the end face. The fixing member 18 includes
Flanges 18a, 18a parallel to each other are provided, and by fitting the flanges 18a, 18a to a connecting portion (not shown) provided on an electronic device (monitor) or the like, the holding member 20 and the electronic device are connected. It can be connected to equipment.

A thread (not shown) is formed around the Y2 side tip of the rotating part 21, and a holding member 19 is screwed to this thread. Then, for example, when the holding member 19 is rotated in the α1 direction, the holding member 19
Direction, and when rotated in the α2 direction, moves in the Y1 direction. Therefore, after the connecting portion of the electronic device such as the monitor is fitted to the fixing member 18, the pressing member 1
9 is rotated in the α1 direction and moved in the Y2 direction, so that the connecting portion is pressed against the pressing surface 1 of the fixing member 18 and the pressing member 19.
9a, the electronic device can be firmly fixed to the holding member 20. Also, the holding member 19 is set to α
By rotating in two directions and moving in the Y1 direction, the holding of the connecting portion is released, so that the electronic device can be easily removed.

The operation of adjusting the supporting device A of the electronic apparatus will be described. As shown in FIGS. 1 and 2, the mandrel 16 a of the tightening member 16 is inserted into the insertion holes 12 d and 12 e of the moving member 12, the insertion hole 13 a of the engagement member 13, and the pressing member 1.
5, the operating member 16b is rotated, and the screw portion 16c is screwed into the screw receiving portion 14A of the adjusting mechanism 14, so that the holding member 20 can rotate around the axis of the shaft 16a. Become.

Further, by increasing the degree of tightening of the tightening member 16, the moving member 12, the engaging member 13, the adjusting mechanism 14, the pressing member 15 and the holding member 20
Can be fixed. That is, by tightening the tightening member 16, the gap d between the sandwiching portions 12b and 12c is reduced.
Will be reduced. Accordingly, since the inner wall surface of the cylindrical portion 12a grips the column 11, the moving member 1 is attached to the column 11.
2 is fixed, so that movement in the Z-axis direction and rotation about the Z-axis can be suppressed. At the same time, the pressing portion 1 of the engagement member 13
3A, 13B, 13C, and 13D press the uneven surface 14B of the adjusting mechanism 14, and at least one of the protrusions a, b, c, and d fits into the concave portion 14b.
Can be prevented from rotating around the mandrel 16a (second axis).

On the other hand, when the tightening of the tightening member 16 is loosened, the distance of the gap d between the holding portions 12b and 12c increases.
Therefore, the moving member 12 moves in the Z direction along the support 11 (first axis).
Axial movement, rotation about the Z axis and mandrel 16a (second
(Rotation about the X axis) is released at a time. That is, in the support device A, it is possible to simultaneously adjust the height of the electronic device in the Z-axis direction, adjust the left and right swing around the Z-axis, and adjust the elevation angle around the X-axis.

FIG. 3 is a front view of the elevation adjustment mechanism (II in FIG. 1).
(I direction arrow view). FIG. 3 shows the positional relationship between the uneven surface 14B and the protrusions a, b, c and d projecting from the tips of the pressing portions 13A, 13B, 13C and 13D. That is, the projections a and b and the projections c and d
Are provided at positions shifted from each other by 180 degrees. However, while the line L1 connecting the projections a and b is parallel to the Z axis (the support 11 as the first axis), the dotted line L2 connecting the projections c and d is predetermined with respect to the Y axis. Is set to have the angle θ. Is set to correspond to an angle corresponding to a half pitch formed by the adjacent convex portions 14a and concave portions 14b.

By setting as described above, for example, when one of the projections a and b is fitted into the recess 14b of the uneven surface 14B, the other projection c and the projection d are connected to the projection 14a.
Can be abutted. Similarly, one protrusion a
When the projection b and the projection b are in contact with the projection 14a, the other projection c and the projection d can be fitted into the recess 14b. That is, a half pitch exists between the adjacent convex portions 14a and the concave portions 14b (that is, one pitch exists between the convex portions 14a and the convex portions 14a and between the concave portions 14b and the concave portions 14b).
When the engaging member 13 is rotated about the axis of the shaft 16a, the projections a and b and the projections c and d can be fitted into any one of the recesses 14b at every half pitch. is there. Therefore, as compared with the case where all the projections always mesh with the recesses and the fitting is repeated at every pitch, the fitting can be performed twice during one pitch, so that a double click feeling is obtained. This makes it possible to double the accuracy of adjusting the elevation angle about the X axis. Further, since it is not necessary to form a fine pitch on the uneven surface 14B side, the strength of the adjusting mechanism 14 can be maintained, and the production cost does not increase.

In the above description, the four pressing portions 13A, 13B, the pressing portions 13C and 13D provided on the engaging member 13, and the four projections a,
Although b, c, and d are shown, the numbers of these pressing portions and projections can be set as appropriate. However, in consideration of uniformly pressing the uneven surface 14B, it is preferable that the number of the pressing portions and the protrusions be set to a multiple of four.

In the above description, the moving member 12 is provided with the engaging member 13 and the holding member 20 is provided with the adjusting mechanism 14. On the contrary, the moving member 12 is provided with the adjusting mechanism 14. Alternatively, the holding member 20 may be provided with the engaging member 13. Further, in the above description, a holding member indicated by reference numeral 20 is shown as a means for fixing an electronic device such as a monitor, but the supporting device of the present invention is not limited to this. Also, the electronic devices supported are not limited to monitors.

[0034]
