Abstract

PURPOSE:To prevent a rotary shaft from rotation due to contact or incorrect using by once adjusting a cap by a finger grip to set up a fixed variable, and then fitting the cap to a panel so that the cap stores the rotary shaft and the rotary shaft is prevented from being easily contacted. CONSTITUTION:A through hole 6a to be engaged with the periphery of an inner shaft 5a of a finger grip 5 is formed on the cap 6 and a fitting part 6b is formed on a peripheral part on one end of the cap 6. The fitting part 6b has a leading projection 6c and a back projection 6d to fix the cap 6 to the panel 4. After releasing the finger grip 5 from the rotary shaft 2, the cap 6 is engaged with the hole 4a of the panel 4. Under said status, the leading end of the rotary shaft 2 is stored in the through hole 6a of the cap 6, so that the leading end surface of the rotary shaft 2 is prevented from being projected from a back opening surface 6e of the cap 6.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a knob device for adjusting volume, color tone, etc. used in electronic equipment such as video tape recorders and televisions.

Conventional configuration and its problems A conventional knob device will be explained using FIG. 1.

In FIG. 1, 1 is an adjustment body that has a rotating shaft 2 and adjusts the volume, etc., 3 is a wiring board provided with the adjusting body 1, and 4 is a rotating shaft 2.
An operation panel 5 having a panel hole 4a through which the
is a knob, and the inner surface of the knob 6 has an inner shaft 6a, and the tip of the rotary shaft 1 fits into a hole 6b formed in the center of the inner shaft 6a, and the knob 5 is fixed thereto. .

With the above configuration, the volume can be freely adjusted by rotating the knob 6.

However, in the above configuration, the knob 5 protrudes from the front of the panel 3, so once the adjustment is made, the knob 6 can be easily set by touching it when the equipment is operated under the same conditions in most cases. This has the disadvantage that the value must be changed and adjusted again.

Purpose of the Invention The present invention provides a method to always set a constant amount without causing the knob to touch, misuse, etc. and operate the device under the same conditions after adjusting once and setting a constant amount. To provide a knob device that can be left in place.

Structure of the Invention The present invention has an inner shaft having a hole that can fit into a rotating shaft provided in an adjustment body for adjusting equipment, and a through hole that can fit into the outer periphery of the inner shaft. The cap has a mounting part on the outer periphery of one end of the cap that can be fitted into a panel hole into which the rotating shaft is inserted, and when the mounting part is fitted into the panel hole, the rotating shaft is The tip portion is housed in the through hole of the cap, so that the rotating shaft cannot be easily contacted from the front surface of the panel.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. In each figure, the same members as those in FIG. 1 are designated by the same numbers and their explanations will be omitted.

In FIG. 2, a cap 6 has a through hole 6a that can be fitted to the outer periphery of an inner shaft 6a of the knob 6. Reference numeral 6b denotes a mounting portion provided on the outer periphery of one end of the cap 6, and includes a tip protrusion 6C and a rear protrusion 6d for fixing the cap 6 to the panel 4.

FIG. 3 shows a state in which the camp 6 is fitted into the panel hole 4a of the panel 4 after the knob 6 is removed from the rotating shaft 2, and the cap 6 is attached to the panel 4. The distal end of the rotary shaft 2 is housed in the through hole 6a of the cap 6, and the distal end surface of the rotary shaft 2 does not protrude beyond the rear opening surface 6e of the cap 6.

As described above, according to this embodiment, during normal use, the
So, if you want to operate the device under the same conditions after setting the key signature of the device's volume, etc. once and setting a certain amount, set the dimension 5 to the rotation axis 2, etc. JfM, ,!
l) By removing it and attaching the cap 6 to the panel 4, it will not be able to easily touch the rotating shaft 2, thereby preventing rotation of the rotating shaft 2 due to contact or misuse, and always maintaining a constant set value. I can do it.

Effects of the Invention As described above, according to the knob device of the present invention, during normal use, the device is adjusted with the knob, and when the device is operated under the condition that the adjustment is made once and the amount is set, ,
The cap is attached to the panel, and the cap accommodates the rotating shaft so that it cannot easily come into contact with the rotating shaft. This prevents the rotating shaft from rotating due to contact or misuse, and allows a constant set value to be maintained at all times. The effect is great.
