Description

[Detailed Description of the Invention] The present invention relates to an improvement of a vehicle instrument box that houses various instruments.

Vehicle instrument boxes, particularly automobile instrument boxes, are generally fixed to an instrument panel, and their position (angle) cannot be adjusted.

Therefore, depending on the driver's body position and sitting posture, the instruments are not necessarily easy to see.

In order to improve this, for example, Japanese Patent Application Laid-Open No. 48-64640
In the example shown in FIG. 13 of the publication, an instrument assembly 35 for an automobile is pivotally connected to the structure 22 via a shaft 39, and its slope is adjusted by an adjustment screw 40. 35 can be tilted and its slope can be adjusted, but its specific structure is unknown.

Further, in Japanese Patent Application Laid-Open No. 50-81133, shafts 6 and 5 are provided at the top and bottom of the display device itself as a display device for electronic equipment, respectively, so that the shaft 6 can rotate around the shaft 5, and the shaft 6 is connected to a support plate 7, 7
’, and fix it with screws 10 (
1 and 2), and by rotating the knob 12 from outside the cabinet 11, the wire 14. A system in which the shaft 6 is moved within the hole 9 by means of 015a to 15c (Fig. 3) is shown, but it is suitable for cases where there is only one display in the cabinet, but many instruments can be moved in the instrument box. It cannot be applied to automobile instrument clusters.

The angle adjustment mechanism is screw 10 or knob 12. When using the wire 14 and the rollers 15a to 15c, the former is troublesome to adjust, and the latter is complicated and may cause a failure in a vehicle that is subject to vibrations, such as an automobile.

Furthermore, as shown in Japanese Utility Model Application Publication No. 49-90143 as an instrument panel for special vehicles, the upper end of the panel 3 to which the instrument 4 is attached is supported by a hinge 3a, and one end of the locking piece 6 is attached to the lower end of the panel. There is a device in which a long groove 6a with several notches is formed, a screw 19 taken on the bracket 2 is passed through this groove, and a wing nut 10 is engaged to fix the panel 3 at a certain angle. However, this structure has the disadvantage that if the panel is to be held securely, the angle at which the panel can be fixed is limited by the number of notches.

Although there is a known angle adjustment mechanism for an inclinometer as shown in Japanese Utility Model Application Publication No. 48-26948, which uses a worm 8 formed on a bundle shaft 7 and a worm wheel 6 that meshes with the worm 8, this is not described here. Equipment (utility development 50-811
Publication No. 33) or a panel equipped with a meter (Utility Model Publication No. 49)
-90143 Publication), but when applied to an instrument box with several built-in instruments, especially an automobile instrument box, a worm and a worm wheel are used. However, due to its weight and vibration, the worm axis may be reversed and the specified inclination angle may not be maintained.This is because the above-mentioned inclination angle changes rapidly. It is expected that something serious will happen.

In view of the above, the present invention allows the angle of the instrument box containing several instruments to be easily and easily adjusted according to the driver's sitting posture or preference, and securely fixes the angle so that it does not change after adjustment. The purpose is to provide a vehicle instrument box that can
The protruding shafts provided on both sides of the instrument box are rotatably supported in an opening opened in the instrument panel that faces the front and expands in the vertical direction, and a worm gear is attached to the protruding shafts. An instrument box rotation angle adjustment mechanism consisting of a worm shaft equipped with an engaging worm and a double nut that is screwed to a threaded portion formed on the worm shaft and fixes the worm shaft to the instrument panel on the other hand. This is the summary.

To explain this in detail using the diagram, 1 indicates various instruments 2a.
, 2b * 2c, 2d is housed in the instrument box, and protruding shafts 1a and 1b are attached to both sides of the instrument box. Inside the opened opening 3a, the opening 3a is fitted into holes 3b and 3C provided on the side surface of the opening 3a, and is rotatably supported.

The protruding shaft 1b pivotally supported by the instrument panel 3 in this manner is rotated and fixed as appropriate by a rotation angle adjustment mechanism, which will be described later.

The rotation angle adjustment mechanism includes a worm gear 41 fixed to the protruding shaft 1b, and a worm 4 that meshes with the worm gear 41.
It is composed of a worm mechanism consisting of 2.

A worm shaft 43 equipped with the worm 42 has a screw 43a formed at its base end, and is attached to the instrument panel 1.
The screw 43a is screwed into a double nut 44, 44' attached to the bottom plate 31 of the instrument panel.

The worm shaft 43 is rotated by an adjustment dial 45 attached to its lower end.

The present invention is constructed as described above, and when adjusting the inclination of the instrument box 1, loosen one side 44' of the double nut, rotate the adjustment dial 45, and the worm shaft 4
3 rotates in a nut 44, and the worm gear 41 rotates via the shaft and the worm 42, so the protruding shaft 1b to which the worm gear 41 is fixed rotates, allowing the angle of the instrument box 1 to be changed. .

In this way, adjust the angle of the instrument box 1, and when it reaches a position where the driver can easily see it, stop rotating the adjustment dial 45 and tighten one side 44' of the double nut, and the worm gear 41
The engagement between the worm 42 and the double nut 44.44'
The instrument box 1 is fixed in that position by both.

As described above, in the instrument box according to the present invention, the projecting shaft provided on both sides of the instrument box is rotatably supported in the opening made in the instrument panel, and meshes with the worm gear attached to the projecting shaft. A rotation angle adjustment mechanism for the instrument box is provided, which consists of a worm shaft equipped with a worm and a double nut that is connected to a threaded portion formed on the shaft and can fix the worm shaft to the instrument panel on one side.
After adjusting the angle of the instrument box using this mechanism, the worm shaft can be fixed with a double nut. Therefore, even if the instrument box is heavy or the worm angle is loose, the worm shaft will not reverse and the inclination angle of the instrument box will not change. The present invention can also be safely applied to automobile instrument boxes that are subject to vibration.

Furthermore, according to the present invention, the instrument box is rotatably supported in an opening in the instrument panel that faces the front and expands in the vertical direction. When tilted upward, the instrument panel blocks light from outside the vehicle, making it easier to see the instruments.
