Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention allows various devices, such as audio amplifiers and tape recorder volume controls, to be adjusted according to their operating conditions.
This relates to a knob on a device that can be operated depending on the purpose.

(Technical background of the invention and its problems) Conventionally, in the above-mentioned devices, two or more types of devices sometimes share a panel.

In such cases, one model may require only one knob on the panel, but the other model may require two knobs, so as a means to share the panel, as shown in Figure 1. The outer dimensions of the knob hole 1 of the knob of the first model and the outer dimensions of the two knob holes 2a and 2b of the second model are the same, and a partition wall 3 is placed between the two knob holes 2a and 2b. It may be provided.

The mold for molding this has a nested structure for the partition wall 3, and for the first model, the part for the partition wall 3 is nested so that the partition wall 3 is not formed. For the second model, the partition wall 3 may be formed by removing the insert.

Another method is to form and mold the partition wall 3 in both models, and then cut the partition wall 3 in the first model.

In the first model, the knob 4 is placed in the knob hole 1.
In the second model, knobs 5a and 5b are inserted into knob holes 2a and 2b, respectively.

When the above-mentioned equipment panels are molded using a mold with a nested structure, there is the inconvenience of having to attach and remove the nest depending on the model, and the inventory amount has to be increased because each model has to be stocked. There are many drawbacks.

Moreover, when cutting after the above-mentioned molding, there is a drawback that cutting is laborious and costly.

(Purpose of the invention) The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and the shape of the knob allows it to be compatible with the first model without cutting the partition wall, thereby making it possible to standardize the panels. The purpose is to measure.

(Embodiment of the invention) An embodiment of the invention will be described below with reference to FIGS. 3 to 6.

Figure 3 shows the panel of the present invention, with two knob holes 6
The fact that a and 6b are formed by the partition wall 7 is the same as in the conventional second model.

Therefore, when using this panel for the second model, the same knobs 5a and 5a as shown in FIG.
5b are inserted into the knob holes 6a and 6b, respectively, and connected to operating means of respective devices, such as a switch.

When this panel is used for the first model, the knob 8 shown in FIG. 5 is used.

This knob 8 is formed with a leg 8a connected to the operating means of the device, and a leg 8b that is simply guided through the knob hole 6b, and the leg 8a and the leg 8b are configured to straddle the partition wall 7. Cavity part 8c into which partition wall 3 is inserted
is formed.

Therefore, if this knob 8 is inserted into the knob holes 6a, 6b, one knob 8 is inserted into the two knob holes 6a, 6b without cutting the partition wall 3, and the appearance is the same as the conventional one. It is.

(Effects of the invention) As mentioned above, in the present invention, the panel separated by the guide hole of two knobs by a partition wall can be used for the first model with one knob and the second model with two knobs. It can be used in common.

Therefore, it is no longer necessary to make the mold complicated by using a nested structure as in the past, or to attach and detach the nest depending on the model to be molded, or to keep stock for each model. It is possible to prevent cost increases based on

In addition, there is no need to incur the trouble or cost of cutting the partition wall after molding.Furthermore, since one knob is inserted into the guide holes of two knobs, the appearance is the same as the conventional first model. This prevents the unsightly appearance of two guide holes being exposed.
