Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a pictorial symbol switch for use with a control panel of an automobile or the like.

2. Description of the Prior Art

A control panel in which a pictorial symbol switch is incorporated is often employed, for example, in an automobile. An exemplary one of conventional control panels for use with an automobile is shown in FIG. 3. Referring to FIG. 3, the conventional control panel shown is generally denoted at 1 and incorporated in a console of an automobile not shown, and a control lever 2 serving as an operating element extends outwardly from the control panel 1. The control lever 2 is mounted for linear reciprocating sliding movement along a linear lever hole or slot 3 formed in the control panel 1. A plurality of pictorial symbols 4a, 4b, 4c, 4d and 4e serving as display sections are indicated in a horizontal row above the lever hole 3. Then, if the control lever 2 is moved to a position corresponding to one of the pictorial symbols 4a to 4e, then an operation corresponding to the pictorial symbol 4a, 4b, 4c, 4d or 4e is performed. Thus, for example, if the control lever 2 is moved to the position corresponding to the pictorial symbol 4c, then warm wind is blown to feet of a driver.

Meanwhile, an exemplary one of conventional meter panels for use with an automobile is shown in FIG. 4. Referring to FIG. 4, the meter panel shown is generally denoted at 5 and has a display section 6 at which a driver is indicated in a pictorial symbol. In this instance, if, for example, a control switch not shown is depressed, then a portion of a driver toward which wind is to be blown is indicated by an arrow mark on the display section 6.

In both of the control panel and the meter panel having such constructions as described above, an operating element and a display section for providing a visual indication corresponding to an operation of the operating element are disposed separately from each other. Accordingly, a panel of an automobile normally has a comparatively large number of display sections thereon, and accordingly, there is a problem that the panel cannot be reduced in size readily.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a pictorial symbol switch which is effective to minimize a panel and to prevent an operation in error thereof.

In order to attain the object, according to the present invention, there is provided a pictorial symbol switch which comprises a first switch unit having a first pictorial symbol indicated on a surface thereof and visually representing a first event which is to take place when the first switch unit is depressed, and a second switch unit disposed adjacent the first switch unit and having a second pictorial symbol indicated on a surface thereof and visually representing a second event which relates to the first event and is to take place when the second switch unit is depressed.

With the pictorial symbol switch, since an operating section and a display section are provided in an integral relationship with each other, a panel or the like in which the pictorial symbol switch is incorporated can be reduced in size. Further, since each of the switch units has a pictorial symbol indicated thereon which represents an event which is to take place when the switch unit is depressed, an error in operation of the switch is prevented.

The pictorial symbol switch may further comprise third and fourth switch units disposed adjacent the first and second switch units, respectively, and having third and fourth pictorial symbols indicated on surfaces thereof, respectively, and visually representing third and fourth events, respectively, which relate to the first and second events and are each to take place when the third or fourth switch unit is depressed.

The above and other objects, features and advantages of the present invention will become apparent from the following description and the appended claims, taken in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a front elevational view of a pictorial symbol switch showing a preferred embodiment of the present invention:

FIG. 2 is a front elevational view of another pictorial symbol switch showing another preferred embodiment of the present invention;

FIG. 3 is a front elevational view showing a conventional control panel; and

FIG. 4 is a front elevational view showing a conventional meter panel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring first to FIG. 1, there is shown a pictorial symbol switch to which the present invention is applied. The pictorial symbol switch shown is generally denoted at 10 and is incorporated in an area of a control panel 10a, for example, of an automobile not shown. The pictorial symbol switch 10 includes a first switch unit 11a having a first pictorial symbol 12a indicated on a surface thereof. The first pictorial symbol 12a represents an operating condition that wind will be blown to the upper part of the body of a driver if the first switch unit 11a is depressed. A second switch unit 11b is disposed just below the first switch unit 11a and has a second pictorial symbol 12b indicated on a surface thereof. The second pictorial symbol 12b represents another operating condition that wind will be blown to the lower part of the body of a driver if the second switch unit 11b is depressed. A third switch unit 11c is disposed on the right-hand side of the first switch unit 11a and has a third pictorial symbol 12c indicated on a surface thereof. The third pictorial symbol 12c represents a further operating condition that wind will be blown to the upper part of the body of a fellow passenger on the rear seat of the automobile if PG,8 the third switch unit 11c is depressed. A fourth switch unit 11d is disposed just below the third switch unit 11d and has a fourth pictorial symbol 12d indicated thereon. The fourth pictorial symbol 12d represents a still further operating condition that wind will be blown to the lower part of the body of a fellow passenger on the rear seat of the automobile if the fourth switch unit 11d is depressed.

With the pictorial symbol switch described above, an operator must only look at the pictorial symbols 12a to 12d and depress that one of the switch units 11a to 11d which corresponds to one of the pictorial symbols 12a to 12d which represents an operation of the automobile the operator wants. Accordingly, even a person who is not very familiar to operation of a switch can operate the switch smoothly. Further, since the switch units 11a to 11d are individually disposed taking a situation of an operator into consideration, an error in operation of the switch is prevented.

Referring now to FIG. 2, there is shown another pictorial symbol switch to which the present invention is applied. The pictorial symbol switch is generally denoted at 15 and includes four switch units 13a, 13b, 13c and 13d disposed in a similar manner as in the pictorial symbol switch 10 shown in FIG. 1. The switch units 13a to 13d have pictorial symbols 14a, 14b, 14c and 14d indicated on surfaces thereof, respectively. In this instance, the pictorial symbols 14a to 14d indicate the volumes of sound from four radio speakers (not shown) disposed at left front and rear locations and right front and rear locations, respectively, in a room of the automobile. Thus, when it is desired to increase the volume of sound from the radio speaker, for example, at the right front location, the third switch unit 13c may be depressed.

It is to be noted that, while the pictorial symbol switches of the first and second embodiments described above are applied for the adjustment of the flow of air and the volume of sound in the room of the automobile, respectively, a pictorial symbol switch according to the present invention can naturally be applied to any other apparatus such as air-conditioning equipments, audio systems and so forth. Further, while either of the pictorial symbol switches of the embodiments described above includes four switch units each having a related pictorial symbol indicated thereon, the number of such switch units is not limited to the specific one, that is, four, and any suitable number of switch units may be provided on a pictorial symbol switch according to the present invention.

Having now fully described the invention, it will be apparent to one of ordinary skill in the art that many changes and modifications can be made thereto without departing from the spirit and scope of the invention as set forth herein.
