Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a turn signal switch and a hazard switch that are installed in vehicles such as automobiles and motorcycles, and is particularly characterized in that the two switches have a composite structure.

Generally, the turn signal switch and the hazard switch are constructed separately and installed at different locations. Therefore, in order to operate the turn signals and the hazard simultaneously, it is necessary to sequentially operate these switches located at separate locations. Nowadays, it is desirable to blink (or turn on) the hazard lamps as necessary even when the turn signal lamps are blinking, and for this reason, it is no longer possible to search for two switch buttons while driving and operate them one after another. It was not desirable from the point of view of safe driving.

Therefore, in the present invention, the above-mentioned two switches are made into a composite structure so that the turn signal switch and the hazard switch can be operated by a single switch lever, thereby solving the above-mentioned drawbacks and combining these switches into a single switch lever. By configuring it as a device, it is advantageous in terms of saving installation space and number of parts.

Accordingly, in the present invention, the rotor is linked to the rotation of the drive shaft, which is provided so as to be able to freely move forward and backward with respect to the body, and the rotor is not linked to the forward and backward movement of the body. A slide block that reciprocates with the rotor is provided in the body, and a sole terminal base facing the rotor and the slide block is fixed in the body, and further,
Between the rotor and the terminal base, power is supplied to the right turn signal lamp at a first position where the rotor is rotated in one direction from the neutral position, and to the left turn signal lamp at a second position where the rotor is rotated in the other direction. A switch terminal connects the left turn signal lamp in the first position to the hazard switch, and a switch terminal connects the right turn signal lamp in the second position to the hazard switch, and connects both the right turn signal lamp and the left turn signal lamp to the hazard switch in the neutral position of the rotor. The present invention is characterized in that it comprises a turn signal switch having a switch terminal to be connected, and the above-mentioned hazard switch comprising a switch terminal that closes when the slide block moves between the slide block and the terminal base. We propose a combination switch for vehicles.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to further clarify the content of the present invention.

FIG. 1 is a front view of a composite switch according to the present invention, and FIG. 2 is a sectional view taken along line A--A in FIG. 1. In these drawings, 1 is a switch body and 2 is a switch lever. The switch button 2 is fixed to one end of the drive shaft 4 with a screw 3.

The drive shaft 4 is fitted into the body 1 through a bearing portion 1a, and is provided so as to be rotatable and movable forward and backward relative to the body 1. As detailed in FIG. 7, the drive shaft 4 has a rectangular tip 4a and a concave-convex portion 4b on one side for forming a click mechanism.
A U-shaped hole 4c for connecting a slide block, which will be described later, is formed at its tip. The band-shaped convex portion 4d prevents the drive shaft 4 from being pulled out more than necessary by moving through the enlarged diameter hole 1b formed inside the bearing portion 1a.

A rotor 5 is fitted onto the tip 4a of the drive shaft 4. As detailed in FIGS. 4 and 5, the rotor 5 has a shaft hole 5a provided in the center, and two terminal receiving holes 5b ₁ , 5b ₂ provided symmetrically with this shaft hole 5a in between.
, a through hole 5c extending from the shaft hole 5a to the outer periphery of the rotor, and a rotation regulating groove 5d having an arcuate cutout in a portion of the periphery.

The rotation range of the rotor 5 is determined by fitting a convex portion 1c provided inside the body 1 into the rotation regulating groove 5d as shown in FIG. Also,
The above-mentioned through hole 5c has steel balls 6a, 6b.
and spring 7 are installed inside as shown in FIG.
The steel ball 6a is brought into contact with the uneven portion 4b of the drive shaft 4 to constitute a click mechanism.

In addition, the steel balls 6b fall into three grooves 1d formed at equal intervals inside the body 1, so that the rotation of the rotor 5 can be temporarily stopped according to the grooves 1d. be. (See Fig. 3) Furthermore, electrical terminals (switch terminals) 8a ₁ , shaped as shown in Fig. 6 are installed in the terminal receiving holes 5b ₁ , 5b ₂ .
8a ₂ is inserted through springs 9a ₁ and 9a ₂ .

On the other hand, a terminal base 10 is fixed to the body 1. As can be seen from FIG. 2, this base 10 has electrical terminals 8a ₁ and 8a ₂ of the rotor 5.
An electrical terminal (switch terminal) constituting a turn signal switch is provided opposite to the switch terminal. FIGS. 8 and 9 are front views of the terminal base 10 (viewed from the upper right side of FIG. 2), and are arc-shaped terminals.
S ₁ and S ₂ are the terminals connected to the right and left turn signal lamps, S ₃ is the terminal connected to the power supply via the flasher unit, and S ₄ is the terminal for the hazard closed by the movement of the slide block, which will be described later. This is a terminal for a hazard switch that is connected to the power supply via the switch and flasher unit. Further, S ₅ and S ₆ are neutral terminals that are connected to the terminals S ₁ and S ₂ in the neutral state of the switch, and these terminals S ₅ and S ₆ are connected to the shorting plate 11 as shown in FIG. There is a short circuit.

Further, the terminal base 10 is provided with a hole 10a for fitting the slide block 12 into the terminal base 10.
The bent pieces formed on parts of S ₃ and S ₄ fit into this insertion hole 1.
It extends along the side wall of 0a. (See FIGS. 10 and 11) However, these bent pieces do not reach the bottom of the insertion hole 10a, but are set to have a length halfway there. On the other hand, terminals S ₇ and S ₈ are provided on the side wall of the insertion hole 10a and are parallel to the above-mentioned bent pieces.
S ₇ is engaged with the shorting plate 11 for electrical connection, S ₅ and S ₆ as neutral terminals are connected to the flasher unit, and terminal S ₈ is connected to the flasher unit. Together, these constitute a hazard switch.

The slide block 12 reciprocates within the insertion hole 10a in conjunction with the drive shaft 4 to open and close the hazard switch. The block 12 is the 12th block.
As detailed in FIGS. 14 to 14, grooves 12a ₁ and 12a _{2 are formed on both sides of the grooves, and electrical terminals 13 are inserted into the grooves 12a 1 and 12a 2} .
It is equipped with a ₁ and 13a ₂ . And the terminal 13
A ₁ and 13a ₂ are constantly pressed outward (in the direction of the arrow in FIG. 13) by springs 14a ₁ and 14a ₂ . Further, the block 12 is provided with a connecting piece 12b having a locking portion at its tip, and the locking portion of the connecting piece 12b is fitted into the U-shaped hole 4c of the drive shaft 4.

The composite switch constructed as described above is configured so that the electrical terminals 8a ₁ and 8a 2 of the rotor 5 are connected to the eighth position by rotating the switch lever ₂ to the N position in FIG.
Move to the position indicated by the chain line in the figure. Therefore, terminals S ₁ , S ₅ ,
Since S ₆ and S ₂ are short-circuited and these terminals are not connected to the power supply terminal S ₃ , neither the right nor left turn signal lamps are lit. When the switch lever 2 is rotated to the L position in FIG. ₁ , the rotor ₅ rotates in conjunction with _this . Move until terminal 8a ₂ short-circuits terminals S ₂ and S ₃ . Therefore, the left turn signal lamp (or left turn indicator lamp) is powered by shorting terminals S ₂ and S ₃ . When the switch lever 2 is rotated to the R position in FIG. 1, the electrical terminal 8a ₁ short-circuits the terminals S ₁ and S ₃ due to the rotation of the rotor 5 in conjunction with this, and the electrical terminal 8a ₂ moves to the position where it shorts terminals S ₂ and S ₄ . As a result, the right turn signal lamp (or right turn indicator lamp) is supplied with power while the terminals S ₁ and S ₃ are shorted.

In addition, when the switch lever 2 is rotated, the steel ball 6b provided on the rotor 5 falls into the groove 1d of the body 1 in order, so that the button 2 is correctly stopped at each of the L, N, and R positions. In addition, the maximum rotation range of the button 2 is within the range of the rotor 5.
It is determined by the rotation regulating groove 5d and the convex portion 1c provided on the body 1. Next, when the switch lever 2 is in any of the L, N, and R positions, power is supplied to the hazard lamps by pulling out the switch lever 2. That is, when the switch lever 2 is pulled out to the right in FIG. 2, the slide block 12 moves to the right in FIG. 2 in conjunction with the drive shaft 4. However, the electrical terminal 13a ₁ of the block 12 short-circuits the terminals S ₃ and S ₇ , and the electrical terminal 13a ₂ short-circuits the terminals S ₄ and S ₈ , respectively.

Therefore, when the switch lever 2 is in the N position in FIG. 1, the electrical terminals 8a ₁ and 8a ₂ of the rotor 5 are in the
Assuming that they are located at the dashed line position in the figure, the terminals S ₃ , S ₇ ,
The right turn signal lamp is supplied with power through terminals S ₅ , 8a _{1 and} S ₁ , and the left turn signal lamp is supplied with power through terminals S ₃ , S ₇ , S ₆ , 8a ₂ and S ₂ to operate as a hazard lamp. Furthermore, if the switch lever 2 is rotated to the L position, the terminals S ₁ , S ₄ and S ₂ , S ₃ are short-circuited by the electrical terminals 8a ₁ , 8a ₂ . Power is supplied to the right blinker lamp via S ₈ , S ₄ , 8a ₁ , S ₁ , and terminals S ₃ , 8a ₂ ,
Since the left turn signal lamp is supplied with power via _S2 , these lamps will operate as a hazard.

When the switch lever 2 is in the R position,
Since terminals S ₁ , S ₃ and S ₂ , S ₄ are under short-circuited condition by electrical terminals 8a ₁ , 8a ₂ , terminals S ₃ , 8
Since power is supplied to the right turn signal lamp through a ₁ and S ₁ and to the left turn signal lamp through terminals S ₈ , S ₄ , 8a ₂ and S ₂ , these lamps operate as a hazard.

Figure 15 shows the state in which the switch lever 2 is pulled out and the hazard switch is closed; however, if the switch lever 2 is pushed back, the slide block 12 moves to the left in the figure, resulting in the state shown in Figure 2, and the hazard switch is closed. to open.

Note that when the switch lever 2 is pulled out, its position is held by the concave and convex portion 4b of the drive shaft 4 and the steel ball 6a, and the withdrawal limit is determined by the convex portion 4d of the drive shaft 4 and the enlarged diameter of the body 1. It is determined by the hole 1b. FIG. 16 is a simplified example of a turn signal and hazard circuit equipped with the above-mentioned composite switch. In the figure, 15 is a battery, 16 is a flasher unit, 17 is a turn signal switch portion, 18 is a hazard switch portion, and 19R is a right side turn signal. Lamp 19L is the left turn signal lamp. Since the switch operation in this circuit is as described above, the circuit description will be omitted.

As described above, the composite switch according to the present invention has a structure in which the turn signal switch has the functions of the turn signal mode and the hazard mode, and operates in the turn signal mode in normal times and in the hazard mode in accordance with the instruction by closing the hazard switch. Therefore, a turn signal switch and a hazard switch can be integrated into one switch device. Therefore, by rotating the switch button, you can operate the turn signal switch, and by pulling out the button, you can operate the hazard switch. It is possible to operate the hazard and the hazard at the same time, and in this respect, the switch operation becomes simple, and this type of switch has an extremely significant practical effect, especially for a switch of this type that is operated by groping while driving. Furthermore, if the compound switch is constructed like this, the switch, which was conventionally assembled in two places, can be attached in one place, which is advantageous in this respect, and the main components of this compound switch are the rotor, terminal base, and Since it is a slide block, its structure is not complicated, and it has the advantage of being less likely to break down.
