Description

[Detailed description of the invention] [Field of application of the invention] The present invention can make it appear as if the pointer axes of the multiple instruments are arranged at the same position in a compound instrument in which multiple instruments are arranged. This relates to eccentric compound instruments.

[Background of the idea]

As a conventional compound meter, there is one having a structure as shown in FIGS. 5 and 6. For example, in the conventional example shown in FIG.
and a second gauge 2 such as a fuel gauge and a thermometer are arranged side by side, but in the case of such a composite gauge, there is a
Since the pointer shafts 7 and 8 of the hands 5 and 6 are positioned, the first meter 1 and the second meter 2
When these instruments are installed side by side, the distance between the needle axes of both instruments becomes large due to the influence of the sizes of the movements 3 and 4 of those instruments 1 and 2, and the indicated amount by both instruments 1 and 2 becomes larger. The display board (scale board) for displaying tended to become large. Furthermore, in the conventional example shown in FIG. 6, the pointing direction of the pointer 6 in the second meter 2 is changed, but also in this conventional example, the distance X between the pointer shafts 7 and 8 of both meters 1 and 2 is shortened. Although the display board could be made smaller, the scale arrangement on the display board was restricted, and there were problems in that an easy-to-read scale arrangement could not be obtained.

[Purpose of invention]

The present invention was developed by focusing on these conventional problems.The pointer shaft of one of the instruments in a compound instrument is made to be eccentric from the drive shaft of that instrument, and the fulcrum of the pointer shaft is made to move along with the rotation of the pointer. To make it possible to displace the pointer axes of both instruments so that it appears as if they are at the same axial position, to make it possible to miniaturize the display board, and to further improve the visibility of instructions. The purpose of the present invention is to provide an eccentric compound instrument that can perform the following functions.

[Example of idea]

The present invention will be explained in detail below based on the embodiments shown in FIGS. 1 to 4.

This composite instrument has a first instrument 11 of a crossed coil type that displays vehicle speed, engine speed, etc., and a second instrument 12 of a crossed coil type that displays fuel, water temperature, etc. The structure of the first meter 11 is a well-known structure in which a pointer 14 is attached to a drive shaft 13 extending from the center of the movement 15.

However, the structure of the second meter 12 has the following features. That is, this second meter 12
is attached via a mounting screw 18 across the upper ends of both support columns 17 provided at both outer ends of the movement 16, and furthermore, a drive shaft 1 extending from the center of the movement 16 is attached.
A bracket 20 having a generally U-shaped planar shape extending substantially perpendicularly to the drive shaft 9 is provided, and support pins 21 are attached to both ends of the bracket 20 in parallel with the drive shaft 19. One end of a substantially oval-shaped link 22 is pivotally attached to these support pins 21, and a symmetrical end portion of a translation link 23 formed in a substantially cross shape in plan is attached to the other end of these links 22. are connected via a connecting pin 24. The other end of this parallel movement link 23 has an engagement long groove 2 that engages a pin to be described later.
5 is formed, and furthermore, a pointer shaft 26 is provided at an end opposite to the end where the parallel movement link 23 and the engaging long groove 25 are provided, and which projects parallel to the drive shaft. 27 has the above drive shaft 19 at one end thereof.
is fixed to the link arm, and an engagement pin 28 parallel to the drive shaft 19 is protruded from the other end of the link arm. is provided with a pin 29 that is engaged with the long engagement groove 25 described above. 30 is a pointer rotatably supported by a pointer shaft 26 provided on the parallel movement link 23, and this pointer 30 has an integrated folding arm 3.
1 is provided, and furthermore, a long groove 32 is formed in this folded arm 31, and in this long groove 32,
The above-mentioned engagement pin 28 is loosely fitted. 33 is a scale plate for displaying the indicated value by the pointer 30, 34 is a scale plate for displaying the indicated value by the pointer 14, and this scale plate 34 has a window through which the scale plate 33 can be seen. 35 is formed.

The above is the configuration of this embodiment.Next, to describe its operation, when the drive shaft 19 rotates, the pointer 30 in the second meter 12 moves to the drive shaft 19.
The link arm 27 attached to 9 rotates, and further, due to the rotation of this link arm 27,
Since the translation link 23 engaged by the pin 29 is displaced, the synergistic effect of the displacement of the translation link 23 and the rotation of the link arm 27 causes the pointer 30 to move as shown by the chain line in FIG. Thus, the robot moves on a rotation trajectory that can be drawn around the virtual center P. Therefore, the virtual center point P is the first meter 1
1 drive shaft 13 so that the first
By combining the meter 11 and the second meter 12, as shown in FIG. The axes 26 can be made to appear as if they are coaxially (concentrically) located. Therefore, the circular scale plate 3 of the first meter 11
Since the window 35 for displaying the scale plate 33 of the second meter 12 can be formed in a part of the scale plate 4, a composite meter can be displayed without increasing the size of the scale plate 34. This has the effect of providing an easy-to-read compound instrument.

[Summary of the idea]

As described above, the present invention provides a first meter 11 having a pointer 14 driven by a movement 15.
and a meter body 1 having a meter drive shaft 19 approximately in the center.
6. Two links 2 approximately parallel to the instrument body 16
2, a parallel movement link 23 is arranged substantially perpendicular to the meter drive shaft 19, and an arm 31 is pivotally supported at the end of the parallel movement link 23 and extends toward the meter body 16. Guideline 3
0, and the arm 3 is fixed to the meter drive shaft 19 and extends toward the pointer 30 and engages both the arm 31 and the translation link 23.
1 and a second instrument 12 equipped with a link arm 27 that drives a parallel movement link 23, and the pointer shaft 26 of the second instrument is arranged close to the pointer shaft 13 of the first instrument. It is an eccentric compound instrument with a distinctive feature.

[Effect of idea]

Therefore, according to this composite meter, the pointer shaft 26 of the pointer 30 of one meter is the pointer shaft 1 of the other meter.
Since both instruments can be arranged in combination as if they were located concentrically with 3, it is possible to display the scale plate of one instrument on a part of the circular scale plate of the other instrument. It is possible to display a composite instrument without increasing the size of the circular scale plate, and furthermore, it is possible to provide a composite instrument that is easy to see due to its shape.
