Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a knob attached to a small rotary switch, etc., and relates to a knob of a small rotary switch etc. that is configured so that a display character indicating the next rotational operation position can be confirmed.

Summary of the invention This invention is an extremely small knob, but from an ergonomic point of view, the knob is provided so that the display character indicating the next rotational operation position can be confirmed, and at least the cover plate of the knob is made transparent. Alternatively, it is a knob of a small rotary switch or the like made of a translucent transparent material.

Conventional technology As shown in Figure 6, the knobs of small rotary switches and the like have traditionally been provided with a display window on the right or left side of the knob, and are made of non-transparent material such as red, black, or blue. was being formed.

Further, this type of knob was formed in a small shape so that the display characters on the top surface of the switch could be seen.

Problems that the invention aims to solve: Conventional small rotary switches and other knobs have a display window on either the right or left side of the knob. As a result of the knob operation being performed by pinching, the fingertips are placed over the displayed characters, which has the disadvantage that the displayed characters are hidden.

Furthermore, since the knob was made of an opaque material, the displayed characters and symbols on the left and right sides of the display window were not visible, making it impossible to determine which direction to turn the knob. I was doing a lot of switching.

In addition, a switch in which the knob was made small so that the displayed characters on the top surface of the switch could be seen had the disadvantage that the rotational torque was large and it was difficult to operate.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore, the purpose of the present invention is to eliminate the above-mentioned drawbacks inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the knob of the small rotary switch, etc. according to the present invention consists of a cover plate attached to the switch body, and a knob protruding from the center of the cover plate. a display window is provided on one of the cover plates on the extension of the knob, an engaging portion is provided on the lower surface of the cover plate to engage with the rotating shaft in an uneven relationship, and at least the cover plate of the knob is provided with a display window. It is made of transparent material.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 is a plan view showing one embodiment of the present invention;
3 is an exploded perspective view of the present invention, FIG. 3 is a rear perspective view of the present invention, and FIG. 4 is a perspective view showing the present invention in use.

1 to 3, reference number 1 indicates a knob according to the present invention, and the knob 1 has a cover plate 2,
It is composed of a knob 3 attached to a cover plate 2.
The cover plate 2 is formed in a circular shape, and a substantially rectangular column-shaped knob 3 is formed on the cover plate 2 in a straight line, passing through the center of rotation and making the longitudinal direction substantially perpendicular to the direction of the rotation axis. cover plate 2 on the longitudinal extension of knob 3.
A recess is formed that enters in the radial direction from the outer periphery, and this recess serves as a display window 4. Said knob 3
is formed in a pointed arrow shape 3a so that its display window side points toward the display window 4. knob 3
, the arrow-shaped part 3a is shorter than the rear part 3b,
In other words, it is attached to the cover plate 2 with a bias. Cover plate 2
A cross-shaped protrusion 5 is provided on the lower surface of the switch 6 and engages in a concave-convex relationship with a cross-shaped recess 7a formed in the rotor or rotating shaft 7 of the switch 6. Note that 7b is an arrow-shaped protrusion provided as an adjustment indicator before the knob 1 is attached to the switch 6, and when the knob 1 is attached to the switch 6, the protrusion 7b is a cover plate. It is loosely fitted into a recess 5a provided at the lower part of 2.

In one embodiment shown in FIGS. 1 to 4, the knob 1 has only the cover plate 2 made of a transparent or translucent transparent material by double molding, but the cover plate 2 and the knob 3 are made of a transparent or translucent transparent material.
Various methods can be considered, such as molding the knob separately and fitting the two in a concave-convex manner, or forming the entire knob from a transparent material and applying treatments such as painting or labeling the knob part. Further, although the display window 4 of the present invention is a recess, it may also be a square hole or a round hole.

When the knob according to the present invention is attached to the switch 6 by fitting the cross-shaped protrusion 5 on the lower surface into the recess 7a formed in the rotor 7 on the upper surface of the switch, as shown in FIG. The switching position is displayed on the display window 4, and codes 8 such as numbers and symbols are formed on the surface of the switch 6 through the cover plate 2 on the left and right sides thereof.
That is, the next switching position is displayed.

FIG. 5 is a perspective view of main parts showing another embodiment of the present invention. This embodiment differs from the above-described embodiments in the engaging portion between the knob and the switch. That is, an engagement recess 11 having a knurled inner surface is provided at the center of rotation of the cover plate 2. The periphery of the tip of the rotating shaft 12 on the switch side is formed into a knurled shape, and the tip of the rotating shaft 12 is engaged with the recess 11.

Effects of the invention The invention is constructed and operates as described above, and the invention produces the following effects.

(1) From an ergonomic point of view, we have provided a display window on the extension of the knob, so even if you pinch the knob with two fingertips when changing the switch, the displayed characters and symbols will not be hidden by your fingertips. can be confirmed and, therefore, can be quickly set to a predetermined switching position while rotating the knob. This is especially effective for extremely small knobs.

(2) Since the cover plate covering the displayed characters is made of transparent material, the entire displayed characters and symbols or the displayed characters and symbols adjacent to the left and right of the display window can be seen, so you can turn the knob in any direction to find the desired object. You can see at a glance whether it is closer to the switching position, and you will not have to perform unnecessary rotational operations. Therefore, it can be used rationally without reducing the life of the switch.

(3) Since the display window is provided as an extension of the knob, the position is displayed on both the display window and the knob, so the setting position is clear and there is no risk of setting it incorrectly.

(4) Since the knob is offset and a display window is provided, the setting position is clear and it is easy to operate even the smallest knob.

(5) Since the engagement part with the switch on the lower surface of the cover plate is cross-shaped, the contact area is large and strong, and the knob has little rattling, making the setting position clear and easy to operate.
