This invention relates to a lever switch device which switches a switch to a predetermined switching state by rocking of an operating lever.

Conventionally, a wiper control switch provided in, for example, a steering column of a vehicle has been provided as an apparatus of this kind, but in such a switch, the wiper is rotated when the operating lever is rotated in a first swing direction parallel to the direction of rotation of the steering. If the motor is rotated in a second swing direction perpendicular to the electric steering, depending on the crane or to switch the motor to the OFF interval, low and high operating states, For example, the Whitshaker motor will turn ON.

Accordingly, such a conventional lever device includes a first movable member which is moved only when the operating lever is operated in the first swing direction and a second movable member which is moved only when the operating lever is operated in the second swing direction. When the first and second movable members are selectively moved by the operation levers, the switch state of the switch is changed in place of the movement state.

Therefore, in such a conventional structure, since a selection mechanism for selectively moving the first and second movable members must be provided in accordance with the moving direction of the operating lever, the configuration is complicated, which makes it difficult to design and manufacture and difficult to miniaturize. In addition, since the switch switched by the first movable member and the switch switched by the second movable member are each independently located at separate positions, these switches are for example to switch the operation of one load. When used for this purpose, both switches must be connected to each other by lead wires, and therefore, wiring is complicated and cumbersome.

This invention is a mirror of the above, and its object is to provide a lever switch device that can simplify the construction, simplify the design, and simplify the wiring by simplifying the configuration.

In other words, this design is designed to allow the reciprocating movement of the switch frame to move the switch to a predetermined switching state according to its movement position, and to operate the lever and the electric lever installed to allow the swing of the electric switch frame. The member is provided so as to sandwich the electric operating lever, and the coupling device is provided for reciprocating the movable member by reciprocating the lever in the first direction. The present invention provides a lever switch device having an inclined portion for reciprocating an electric movable member even when the operating lever is reciprocated in a second direction crossing the first direction.

17 to 20 are opposed to the rocking pin (13) 凹 part formed on one side of the part 16 to face each other at a predetermined distance from each other in the up and down direction, which gives an operational feeling to the arrow A of the operating lever 4 and the rotation in the opposite direction, and the operating lever The operating lever 4 is returned to the neutral position N when (4) is rotated in the direction of arrow B or the opposite direction with respect to the pin 11.

That is, each of the shoulders 17 to 20 incline the upper half and the lower half between the middle portions so that the center portion in the up-down direction is the deepest (see FIG. 3), so that the swing pin 13 has the coil spring 15 The operating lever 4 is given a return force to return to the neutral position N according to the force to move toward the center of each of the concave portions 17 to 20 by the elastic force of.

21 is a switch base which is a part of the switch frame, and 22 is a switch cover which encloses the switch base 21, and these are fixed by nent so as to face the other end of the lower operation lever 4 of the base member 1.

23 to 28 are fixed contactors protruding in parallel to the upper surface of the switch base 21 at substantially equal intervals, and 29 and 30 are the same switch base to face the fixed contactors 25 and 26 at predetermined intervals. The fixed contactors protruding from the upper surface of the 21, and the fixed contactors 24 and 26 are respectively provided on a predetermined portion of one metal plate which is partially embedded in the switch base 21, and is electrically connected. In addition, the fixed connectors 23, 27 and 30 are also connected in the switch base 21 by electric warfare. 31 denotes six connection terminals protruding from the lower side of the switch base 21, for example, which are arbitrarily connected to the above-described fixed contacts 23 to 30, and below the switch base 21, the connection terminal 31 is provided. To guide and maintain plugs that are A plurality of parts 32 protrude.

33 is a movable member formed of, for example, an insulating material, which is sandwiched between one side portion 22a of the switch cover 22 and the guide rib 22b protruding from the switch cover 22. 22) It can slide linearly.

34 and 35 A movable contact made of a metal plate bent into a shape, and supported on the lower side of the movable member 33 so as to be movable up and down, and the contactor 34 on one side is fixed as the movable member 33 moves. And the movable contactor 35 on the other side selectively contact the fixed contacts 29 and 30 as the movable member 33 moves. And the lower surface of the movable member 33 is formed with longitudinal holes 36 facing the central portions of the movable contacts 34 and 35, respectively, and coil springs inserted into the longitudinal holes 36, respectively. By 37, the movable contacts 34 and 35 are always urged in the direction of the switch base 21.

38 and 39 are two protruding pins protruding from the upper surface of the movable member 33, and they protrude upward with a long hole 22c installed in the switch cover 22, and between the protruding pins 38 and 39. The operating lever 4 is sandwiched.

40 is a coupler formed therebetween by projection pins 38 and 39, the coupler 40 being slightly larger than the outer diameter of the operating lever 4 and viewed from the side of the operating table 12 in the upper half. When the left incline is at an angle of about 45 degrees, the left incline has a granular inclined portion 40a, and the lower half thereof is perpendicular to the switch base 21. When the operating lever 4 is positioned at the neutral position N, the operating lever 4 is positioned at the upper and lower intermediate positions of the coupler 40.

41 and 42 are stopper members integrally protruding from the upper surface of the switch cover 22 to restrict the rotation range of the arrow lever A direction and the opposite direction of the operating lever 4.

43 is a restricting member protruding in the direction of the stopper member 42 at the upper end of the stopper member 41, which indicates that the operating lever 4 is rotated between the pins 11 at the neutral position N in the direction of arrow B. FIG. The clearance 44 through which the operation lever 4 can pass is formed between the front-end | tip part of this fungicide member 43, and the stopper member 41. As shown in FIG.

Therefore, in a state where the operating lever 4 is rotated in the opposite direction of the arrow A to reach the stopper member 42, the operating lever 4 can be rotated in the direction of the arrow B around the pin 11.

45 is an inclined guide portion which is opposed to the restricting member 43 in the upper half of the stopper member 42, which is inclined away from the restricting member 43 as it goes upward.

On the other hand, when the operating lever 4 is brought into contact with the stopper member 42 at the neutral position N, the swing pin 13 is brought into contact with the middle portion of the inclined surface 17a of the concave portion 17. Since the swing pin 13 always tries to swing the inclined surface 17a in the direction of arrow X by the elastic force of the coil spring 15, the operating lever 4 is given a turning force in the direction opposite to the arrow A. Therefore, when the operating lever 4 is rotated in the direction of the arrow B around the pin 11 while the operating lever 4 is in contact with the stopper member 42, the operating lever 4 burns the coil spring 13 described above. As the shaft portion 7 of the holder 5 rotates with respect to the shaft holes 8 and 10 as it is moved while maintaining the state in contact with the inclined guide portion 45 by the force, it rotates slightly in the direction opposite to the arrow A. Is displaced.

Therefore, at this time, the operation lever 4 swings toward the arrow C direction.

46 is an insertion pin inserted in the longitudinal hole 47 of the holder 5 so as to be slidable, one end of which is opposed to the outer periphery of the operating lever 4 and the other end of which is opposed to the perforation 48 of the switch cover 22. do.

49 is a movable spring contactor whose one end is fixed on the switch case 21 so as to face the insertion pin 46. The fixed contactor 50 of the switch base 21 is opposite to the other end side thereof. It is fixed on the upper surface.

In the electric circuit shown in FIG. 8, 51 is a battery, 52 is a wiper motor, 52a, 52b, and 52c are a furus terminal B, a high speed terminal H, and a low speed terminal of the wiper motor 52. L), 52d is an auto-stop cam switch of the wiper motor 52, 53 is a weesha motor, 52 is an interval control circuit, and each of the fixed contactor 23 to the contactor 30 and the contactor The movable connector 49 is connected as shown in the figure.

Next, the operation of the embodiment of the present invention configured as described above will be described.

First, when the operating lever 4 is turned to the " OFF " position where the operating lever 4 is rotated to the maximum in the opposite direction to the arrow A in the neutral position N to reach the stopper member 42, the swing pin 13 is formed as described above. The wiper motor 52 stops because the movable contactor 34 closes between the fixed contactor 24 and the fixed contactor 25 in this state while opposing the middle of the inclined surface 17a of (17). Indicates the state. Next, when the operating lever 4 is rotated about 10 degrees in the direction of arrow A in the " OFF " position to the " INT " position, the swinging pin 13 is opposed to the convex portion 18 so that the movable contactor 34 The fixed contactor 25 and the fixed contactor 26 are attached, and the movable contactor 35 closes between the fixed contactor 29 and the fixed contactor 30. In this state, the interval control circuit 54 is operated, and as is well known, the wiper motor 52 is intermittently energized and rotated at a low speed.

When the operating lever 4 is rotated about 10 degrees from the "INT" position in the direction of arrow A to the "LO" position, the swing pin 13 is opposed to the convex portion 19. In this state, the movable contactor 34 closes between the fixed contactor 26 and the fixed contactor 27 so that the wiper motor 52 is continuously operated at a low speed. When the operating lever 4 is rotated about 10 degrees from the "LO" position in the direction of arrow A to the "HI" position, the operating lever 4 touches the stopper member 41, and the swing pin 13 is moved. Opposite the concave portion 20, in this state, the movable contactor 34 closes between the fixed contactor 27 and the fixed contactor 28 so that the wiper motor 52 continuously operates on the highway.

In this manner, when the operation lever 4 is connected to the neutral position N and oscillated in the direction of arrow A, which is the first oscillation direction, and vice versa, the movable member 33 having the protruding pins 38 and 39 becomes a switch cover ( 22, guided in one side portion 22a and guide ribs 22b to reciprocate and slide in the direction of arrow a and the opposite direction, and moveable contactor 34 according to the movement position of the movable member 33; The switching state of the switch 35 and the fixed contactor 23 to the fixed contactor 30 is changed.

On the other hand, the operating lever 4 can be rotated from the neutral position N to the opposite direction of the arrow B at any of the positions "OFF", "INT", "LO", and "HI", and is operated at the position of "HI", for example. When the lever 4 is rotated in the opposite direction to the arrow B, the insertion pin 46 slides in the direction of the arrow b to press the movable contactor 49, and as a result, the movable contactor 49 and the fixed contactor 50. Since the top is closed, the upper outer surface 53 is energized to operate. The upper shaft motor 53 is operated as described above even when the operation lever 4 is rotated in the opposite direction to the arrow B in the neutral position N in a position other than "HI". In addition, the operating lever (4) is always subjected to the force in the neutral position N direction by the inclination of the swing pin 13 received the force of the coil spring (15) and the up and down direction of each of the concave portion 17 to the concave portion (20). Therefore, the upper shaft motor 53 is operated only while the operation lever 4 is rotated in the opposite direction of the arrow B and maintained in that state, and the operation lever is immediately released when the operation state of the operation lever 4 is released. 4) is returned to the neutral position N, and the upper shaft motor 53 stops.

Thus, if the operating lever 4 is oscillated in the " OFF " position from the neutral position N as described above in the direction of arrow C, i.e., in the second oscillation direction intersecting with the aforementioned first oscillation direction, for example about 10 degrees By this operation, the part facing the stopper member 42 of the operation lever 4 is moved along the inclined guide portion 45 from the neutral position N to the position D shown in FIG.

On the other hand, since the operation lever 4 moves in the inclined portion 40a of the coupler 40 in the process of moving from the aforementioned neutral position N to the position D, the operation lever 4 is moved by the inclined portion 40a. 33) slides from the position in the opposite direction of the arrow a to the " LO " position, as a result of which the movable contactor 34 closes between the fixed contactor 23 and the fixed contactor 24. As shown in FIG. Then, the wiper motor 52 is rotated at a low speed to operate as if the operating lever 4 is rotated to the "LO" position.

In this state, the operating lever 4 is actuated by the elastic force of the coil spring 15 and the return force to return to the neutral position N due to the inclination of the recess 17, while the operating lever 4 is held. However, if the movable member 33 is held in the "OFF" position and the operation lever 4 is released, the operation lever 4 is moved back to the neutral position N by the "OFF" position, and at the same time, the reverse operation is performed as described above. The member 33 slides in the direction of the arrow a in the "LO" position to become an "OFF" denture.

Thus, according to the first embodiment, when the operating lever 4 is moved about 10 degrees in the direction of arrow C when the operating lever 4 is in the "OFF" position, the wiper motor only remains while the operating lever 4 is held. The operation 52 can be operated at a low speed, and can be stopped immediately by releasing the holding lever 4, so that, for example, when the wiper is only to be operated for a short time, the operation is extremely simple.

That is, when this operation is performed by the rotation operation of the arrow A direction and the opposite direction of the operation lever 4, the operation lever 4 is rotated about 20 degrees from the "OFF" position to the arrow A direction, and is the "LO" position. After the predetermined time has elapsed, the rotation lever 4 needs to be rotated about 20 degrees in the opposite direction of the arrow A from the "LO" position to be in the "OFF" position, and the rotation angle is also indicated by the arrow C. The operation is cumbersome because it requires about twice as much as when swinging in the direction.

Further, in the above configuration, only one movable member 33 is moved even when the operating lever 4 swings in the direction of the arrow C, or when the operating lever 4 rotates in the direction of the arrow A and vice versa. As a result, the wiper switch can be switched to a desired state, without requiring a complicated selection mechanism such as a conventional structure consisting of two switches in which separate movable members are selectively moved according to the swinging direction of the operating lever. Economical and simple to configure

In particular, in the first embodiment of the present invention in which the same switching device or related switching device is selected even if the swinging direction of the operating lever 4 is different, such as a wiper switch, two switches having two movable members are provided. Compared with the conventional structure in which the desired switching state is obtained by means of the present invention, the number of the fixed and movable contacts constituting the wiper switch can be minimized, and the lead wire connecting the two switches as in the conventional structure. Etc. are also unnecessary, and the structure becomes extremely simple as a whole.

9 and 10 show other modifications of the present invention, and only parts different from the above-described first embodiment will be described.

55 is protruded on the side opposite to the guide rib 22b which is one side of the movable member 33; Part 56 is a leaf spring-type movable contactor which is fixed to a terminal 57 protruding from one end of the switch base 21, and two fixed connectors 58 and 59 are formed as if the other end thereof is sandwiched. In general, the movable contactor 56 is connected to the fixed contactor 58. 56a is Protruding bent to the movable contactor 56 so as to oppose the unit 55 When the movable member 33 is moved in the opposite direction of the arrow a as in the previous embodiment by moving the operating lever 4 in the direction of arrow C in the " OFF " The part 56a is formed in the movable member 33 It is pressed by the part 55, and as a result, the movable contactor 56 rotates in the direction of the arrow in opposition to its spring spring force, and is connected to the fixed contactor 59 away from the fixed contactor 58. The fixed contactor 23 of the above embodiment is to be placed separately as being replaced by the fixed contactor (59).

Thus, when the movable member 33 is moved in the opposite direction to the arrow a and the movable contactor 56 is connected to the fixed contactor 59, the movable contactor 56 and the fixed contactor 58 are opened, and as a result, Since the fixed contactor 24 is separated from the wiper motor 52 which is a substantial load, the movable contactor 34 closes between the fixed contactor 24 and the fixed contactor 25 in the state. It does not cause a short circuit inside the wiper switch even in the state. In other words, the wiper motor 52 can be driven at a low speed as in the first embodiment only by moving slightly in the direction opposite to the arrow a in the “OFF” position of the movable member 33. The distance can be significantly reduced in comparison with the case of the foregoing embodiment.

Therefore, the swing angle can be made smaller when the operating lever 4 swings in the direction of the arrow a, and the operation speed can be improved as well as the operability is improved.

The inclined guide portion 45 effectively works to increase the amount of movement of the movable member 33 with respect to the operation angle of the operation lever 4, but this may be installed as necessary.

This design has an inclined portion in the engaging tool which is installed to reciprocate on the switch frame so that the switch can be switched to a predetermined switching state according to the moving position so as to sandwich the operation lever. From the configuration in which the movable position of the movable member can be changed with both when the operating lever is reciprocated in the first direction and reciprocated in the second direction crossing the first direction. It is possible to provide a lever switch device that can simplify the configuration, simplify the design and manufacture, simplify the wiring, and simplify the wiring thereof.
