Description

[Detailed description of the invention] This invention relates to a dial scale for radio receivers, etc. In a type in which the dial scale is separate and assembled by attaching it to a fixed base, the dial scale is Use simple and many parts to prevent the dial scale from expanding or contracting and warping due to the surrounding environment, i.e. high temperature, high humidity conditions, etc. after being attached to the fixed base. Moreover, the dial scale is designed to be able to be attached to the stationary base body by a simple operation without being restricted by its plate thickness.

Conventional methods for attaching this type of dial scale include providing a plurality of fixing holes (approximately 4) at the left and right ends and the center of the dial scale, and inserting screws into these fixing holes to attach the scale.
In addition, this prevents the dial scale from warping or bending, but in this case, the screws inserted into the multiple fixing holes can be seen.
In particular, the fixing point in the center part was unsightly and had the disadvantage of detracting from the appearance.

This invention provides a dial scale mounting device that eliminates these drawbacks, prevents the above-mentioned warpage, and simplifies installation without being subject to restrictions on the thickness of the dial scale. .

Fig. 1 is an exploded perspective view showing an embodiment of the dial scale mounting device of this invention, Fig. 2 is a side sectional view thereof, and Fig. 3 is a side sectional view showing the dial scale installation state. be.

In the figure of the kotara, 1 is a stationary base, 2 is a dial scale attached to this, and both are molded from synthetic resin.

The fixed side base 1 is provided with a substantially horizontal mounting section 3 extending forward from the lower part thereof, and a plurality of mounting sections (3 in the figure) projecting from the front surface of the mounting section 3 at appropriate intervals. ) convex portions 4 are provided.
Reference numeral 5 denotes an inverted V-shaped engagement groove that opens downward and has an inclined surface 5a so as to engage the upper edge 6 of the dial scale 2, and is located above the stationary base 1 almost parallel to the above-mentioned placement part 3. formed in the part.

The dial scale 2 is provided with an upper edge 6 having an inclined surface 6a capable of engaging (fitting) with the engagement groove 5 of the fixed base 1, and a lower edge 6 with an inclined surface 6a capable of engaging (fitting) with the engagement groove 5 of the fixed base 1. An edge portion 7 is provided which can be placed and slid on the placement portion 3 of the stationary base 1, and this edge portion 7 has the plurality of convex portions provided on the placement portion 3 of the stationary base 1. A plurality of (three in the figure) recesses 8 that can fit into the protrusion 4 are provided at positions corresponding to the recesses 4 .

Further, the fixed side base body 1 and the dial scale 2 are each provided with one fixing hole 9, 9' on one side as shown in the figure, and a screw (not shown) is inserted into each fixing hole 9, 9'.
etc., to fix the two.

Here, in order to attach the dial scale 2 configured as described above to the stationary base 1, first, the upper edge 6 of the dial scale 2 is fitted into the engagement groove 5 formed above the stationary base 1, and The plurality of recesses 8 of the dial scale 2 are connected to the fixed side base 1.
The edge portion 7 of the dial scale 2 is placed on the placement portion 3 of the stationary base 1.

Next, from this state, the dial scale 2 is slightly moved along the stationary base 1 with the inclined surface 6a of the upper edge 6a and the inverted V-shaped engagement groove 5 aligned, and the above-mentioned Stop at a position where each fixing hole 9, 9' fits, and insert a screw or the like into these fixing holes 9, 9' to fix it.
The installation is completed as shown in the figure.

By configuring this device in this way, the dial scale 2 has an upper edge 6
It goes without saying that they are securely fixed (fitted) in the inverted V-shaped engagement groove 5 by the inclined surfaces formed on both sides, and the plurality of convex portions 4 of the stationary side base 1 are fixed downwardly. The front part 7' of the edge part 7 of the dial scale 2 is fixed so as to be pressed and clamped, and it is fixed only on one side through the fixing holes 9, 9' with screws or the like, so that there is no means for attaching and operating the dial scale 2. This dial scale 2 has an inverted V-shaped engagement groove 5 on the stationary base 1 and an inclined surface 6 on the upper edge 6 of the dial scale 2.
Since the inverted V-shaped engagement grooves 5 are organically engaged with each other, even if a material of an arbitrary thickness is selected for the inverted V-shaped engagement grooves 5 formed in advance, the inclination of the inverted V-shaped engagement grooves 5 will not change. It is only necessary to set the inclined surface 6a in accordance with the surface 5a, which provides flexibility in the plate thickness during design, and since only one screw is required for fixing, it is not only advantageous in terms of cost. This simplifies the installation work. Furthermore, the dial scale 2 is able to withstand warping and bending caused by changes in the surrounding environment after installation, such as expansion and contraction due to changes in conditions such as high temperature and high humidity. The dial scale 2 is located only at one location on the side, and at other locations due to the plurality of convex portions 4 provided on the fixed side base 1.
Since the end edge portion 7 of the holder is fixed in such a manner as to be pressed, it has a degree of freedom against deformation, and therefore has the advantage of being able to prevent warping or bending without causing it.

In the embodiment, the concave portion was provided at the lower portion of the dial scale, and the convex portion was provided at the lower portion of the stationary base, but these may be provided on the opposite side, that is, the upper portion.
