Description

[Detailed Description of the Invention] The present invention relates to a dial device that can slide smoothly.

A conventional example is shown in FIG. In a conventional dial device, a pointer guide 2 serving as a guide for a pointer 3 is formed in a polystyrene cabinet 1. The guide groove 4 of the pointer 3 is the guide part 2 of the cabinet 1.
It is installed and slides in the direction of the arrow,
Since the A direction of the guide part 2 is large, the guide groove 4 of the pointer 3 and the guide part 2 cannot be reliably engaged. In addition, the guide part 2 is deformed due to molding shrinkage, and the pointer 3
The problem was that it was difficult to slide.

The present invention eliminates the drawbacks of the conventional method, and by providing the cabinet with a slanted wall portion that contacts and supports the pointer member, and setting the height of the guide portion to a height that does not cause molding shrinkage, the pointer member can slide smoothly. The purpose is to obtain a dial device with a

The present invention will be explained based on the drawings.

FIG. 2 shows an exploded perspective view of the dial device of the present invention.

In the figure, 1 is a cabinet, 5 is a pointer member, 6 is a slanted wall portion of the cabinet 1, and 7 is a slanted wall portion 6.
It is a groove-shaped guide part provided on the outside of the upper part of the guide rail part 7-1, which is one side wall part with a trapezoidal cross section on the extension of the slanted wall part 6, and the rear surface of the slanted wall part 6. It has a reinforcing rib 7-3 that protrudes to reinforce the guide rail portion 7-1, and the guide rail portion 7-1 is attached to the tip of the reinforcing rib 7-3.
A rib 7-2 is provided in parallel with. This rib 7-2 is used for other members. 8 is a pointer piece, 9
10 indicates a sloped portion provided integrally with the pointer 8, and 10 represents a groove-shaped sliding portion provided on the upper outer side of the sloped portion 9.

Next, the structure and operation of the dial device of the present invention will be explained.

A slanted wall part 6 is provided on the cabinet 1 so as to be inclined at an obtuse angle slightly larger than a right angle, and a guide part of which the slanted wall part 6 is a part is provided on the outside of the upper part of the slanted wall part 6. The inclined wall portion 6 and the guide portion 7 are integrally formed with the cabinet 1. The pointer member 5 includes a pointer 8, a slope portion 9, and a sliding portion 10 that are integrally formed. Sliding part 10
has a groove shape that opens downward, and when viewed from the side, the groove shape also opens downward so that it forms a trapezoid. When the sliding portion 10 of the pointer member 5 is engaged with the guide rail portion 7-1, the guide rail portion 7-1 is also trapezoidal, and the groove shape of the sliding portion 10 is also trapezoidal, so that they can be fitted without play, and the slope of the slanted wall portion 6 can be adjusted. Since the slope portions 9 and 9 have the same slope, the pointer member 5 can be mounted tightly on the cabinet 1. By providing the inclined wall portion 9 on the cabinet 1 and supporting it in contact with it in this manner, the height of the guide portion 7, particularly the guide rail portion 7-1, can be reduced. In the embodiment of this invention, the guide rail portion 7- of the guide portion 7 is
Comparing the height B of 1 with the height A of the conventional guide part 2, B is 60% of A, and the height of B can be set to a height that does not cause shrinkage deformation during molding. If the height B of the guide rail portion 7-1 is small, the pointer member 5
Since the sliding portion 10 is also small and there is a risk of it falling off during sliding, the pointer member 5 is provided with a sloped portion 10-1 for supporting the pointer member 5 by the cabinet 1.

As described above, in the present invention, the guide section consisting of the reinforcing rib 7-3 provided on the rear surface of the inclined wall section 6 and the guide rail section provided on the upper part of the inclined wall section is integrally molded with the cabinet, and the guide rail section is formed integrally with the cabinet. The height can be set to a height that does not cause molding shrinkage. This results in effects such as smooth sliding with little backlash when the pointer member slides.
