Description

SPECIFICATION Pictorially Illustrated Switching Device The present invention relates to a pictorially illustrated switching device used for operating various devices of an automotive vehicle. More particularly, the present invention relates to a very thin type pictorially illustrated touch switch used for the above purpose.
It has been known to operate loads or devices such as various lamps, heater or the like in an automotive vehicle by a driver by identifying switches provided for respective loads and illustrated by symbols or marks.
As the recent tendency, such designations on the switches or the like have been changed to pictorial illustrations from the traditional literal sign illustrations for the convenience of the user.
In the known practice, for instance, in an automobile vehicle, standarized pictorial symbols are put on the knobs of switches or the like. In this case, the meaning of the pictorial symbol illustrating the function of the corresponding switch may be realized easily. However, the switches are generally provided independently of each other and from the actual arrangement for the parts to be controlled.
It is preferred also in view of safety of driving the vehicle that these switches are made to clearly indicate by illustration the kind thereof and an easy recognition for the function and for easy handling even by a first time user.
Also in the general controlling equipment, it is preferred to arrange as many switches as possible in a small limited space.
The applicant of the present invention has proposed pictorially illustrated switches under Japanese patent application numbers 68,313/78 and 69,850/78. These switches are formed to be switched on by depressing corresponding switching positions on a flexible display board illustrated with a picture of a vehicle. For instance, by depressing the boot lid portion of a picture of an automotive vehicle, an opener of the boot lid is operated. Such a pictorially illustrated switch is convenient in easy illustration of positions of the flexible display board to be depressed. However, such a construction is still inconvenient in that the identification of the respective switch position may still be insufficient if a plurality of switches are arranged in a limited space.
The present invention has for its object to improve the abovementioned inconveniences.
The present invention provides a pictorially illustrated switching device in which the switching position of the flexible display board is provided with a stepped portion in order to make it easier to find the switching position during the switching operation in such a pictorially illustrated switching device.
In the accompanying drawings:- Fig. 1 a is a perspective view for showing one embodiment of a pictorially illustrated switching device of the present invention; Fig. 1 b is a cross-sectional view taken along the line I-I of Fig. 1 a; Figs. 2a, 2b, 3a, 3b; 4a, 4b; and 5a, Sb are perspective view and cross-sectional views, respectively, showing slightly modified embodiments of the present invention; Fig. 4c is a further alternative embodiment for Fig. 4b; and Figs 5a and 5b are perspective and cross-sectional views, respective of a further embodiment.Figs. 1 a and 1 b show a first embodiment of the present invention and Fig. 1 a is a perspective view and Fig. 1 b is a crosssectional view taken along the line I-I thereof.
Referring to these figures, reference numeral 1 designates a flexible display board having a picture of a simplified plan view of a vehicle and made of plastics. At the switching position for opening or closing the power operated windows, projections or raised portions 2 having an arrow shape for showing the direction of opening or closing the window are formed integrally from the board 1. Inside the hollow space of the arrow shaped projections 2, pads 13 are provided.
Reference numeral 3 designates a switching position for operating the boot lid opener.
Conductors 5 are provided at the rear surface of a flexible printed base plate 4 at locations corresponding to each of the switching positions.
Slits 6 are so provided in the printed base 4 as to surround each of the conductors 5. The slits 6 are provided in order to avoid any occurrence of malfunction when a switching position is depressed. The slit 6 is to prevent operation of other switches in other switching positions by the depressing force for one switching position.
However, this slit 6 may be dispensed with provided that there is a certain spacing between the respective switching positions.
A plastic base plate 7 is provided underneath the conductor 5. The plastic base plate 7 has cut out holes at locations corresponding to each conductor 5 as better seen from Fig. 1 b. In these holes, blocks of pressure sensitive conducting rubber 8 are embedded. This pressure sensitive conducting rubber 8 is made of a pressure sensitive resistive body, which abruptly varies its conductivity from a substantially insulative condition of severals tens of MQ to a conductive condition of several tens of Q upon application of a pressure exceeding a certain limit for instance 0.1 to 2 kg/cm2. This pressure sensitive conducting rubber conducts in a direction of the exerted pressure. This base material is not limited to rubber and it may be formed of an elastic material such as a plastic or the like.
Reference numeral 9 designates a hard printed base plate. Each one of pairs of electrodes 10 and 10' are provided at each of the switching positions on the surface of the printed base plate 9. These electrodes are connected to a corresponding number of terminals 11 arranged on a projected end portion of the printed base plate 9.
The abovementioned flexible display board 1, the flexible printed base 4, the conductors 5, the plastic base plate 7 embedded with the pressure sensitive conducting rubber 8 and the printed base plate 9 are stacked as shown in Fig. 1 b and assembled in an outer frame 12 for instance by bending the edge of the frame 12 and thus the switch device is formed.
The manner of use of the aforementioned switching device of the present invention will be explained hereinafter. When a driver of the vehicle depresses a switching position corresponding to a desired load, the pressure sensitive conducting rubber 8 is pressed by the flexible display board 1 via the printed base plate 4 and the conductor 5 and changes its conductivity and assumes a low resistive conducting situation in the top and bottom direction. By this change of the conductivity, one pair of the electrodes 10 and 10' are connected electrically through a corresponding conductor 5 so that a load connected to said one of the pair of electrodes is operated by the source connected to other one of the electrodes.In such operation, the driver not only visually identifies the switching position on the flexible display board but he can identify the raised portion 2 by his finger so that he can identify the switching position more definitely. As mentioned in the foregoing embodiment, by arranging the switching positions corresponding to loads which may be operated during driving of the vehicle, such as power windows, to have the raised portions 2 and the other switching positions, which should not be operated during driving, such as the boot lid opener, to be flat, the drive can easily identify by finger touching only for switching positions which he wants to operate during driving.
Figs 2a and 2b represent a second embodiment of the present invention and Fig. 2a is a perspective view and Fig. 2b is a crosssectional view of the flexible display board.'This embodiment is to provide raised portions 21 in the shape of arrows at switching positions for operating the power windows on the flexible display board 1. The other portions of this embodiment are same as the foregoing embodiment so that a duplicate explanation is omitted. By using the raised portions 21 the same effect as the first embodiment can be obtained.
Figs. 3a and 3b show a third embodiment of the present invention and these figures are similar to Figs. 2a and 2b. This embodiment provides reentrant portions 31 of arrow shape at the switching positions for operating the aforementioned power windows.
Figs. 4a, 4b and 4c show a further embodiment of the present invention. This embodiment provides a plurality of raised strips 41 at the arrow shaped switching positions for operating the power windows in order to make an easy identification by touching with the fingers. These projecting strips may eitherte saw-tooth shaped as shown in Fig. 4b or more smoothly shaped as shown in Fig. 4c.
In the foregoing examples of the present invention, the conductor 5 is provided on the upper surface of the pressure sensitive conducting rubber 8 and a pair of electrodes 10 and 10' are provided at the lower surface thereof.
However, the switching device of the present invention can be made, as shown in Fig. 5a and Sb, to place conductors 5 and 5 at upper and lower surfaces of the pressure sensitive conducting rubber 8 respectively, and to connect the respective conductors 5 and 5 to a plurality of terminals 11 and 11 provided at the projecting end portions of the upper and lower printed base plates 4 and 9, respectively.
In the foregoing explanation, the embodiments of the present invention have been explained for pictorially illustrated switching devices for use in an automotive vehicle. However, the present invention is not limited to such use only and it may equally be applied for a pictorially illustrated switching device for use in vehicles other than an automotive vehicle or general controlling equipment or the like.
As has been mentioned above, the pictorially illustrating switching device according to the present is provided with stepped portions at the switching position of the flexible display board.
Accordingly, the operator may identify the switching position not only by visual recognition but also by the contact with the finger so that a more definite identification of the switching position and thus a more steady and easy switching operation becomes possible. By such additional identification by finger contact of the switching positions, the switching operation becomes easy. This results, more especially in the case of the pictorially illustrated switch used for an automotive vehicle, in improved safety and steady driving.
