Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch device in which an operation section of a switch button is configured to be pushed and pulled by a human finger, and more particularly, to the operation section. 1st operation by pressing
More particularly, the present invention relates to a switch device for executing a second operation by pulling an operation unit, and more particularly to a switch device effective for electrically controlling the opening and closing of a window. 2. Description of the Related Art Conventionally, for example, in the case of a power window switch of a vehicle, it has been disclosed in Japanese Utility Model Laid-Open Publication No.
No. 321. In this conventional example, the operation portion of the switch button is configured to be tilted in a seesaw shape about a support shaft. That is, this operation unit is normally held in a neutral position in a symmetrical state so that the upper surface of the operation unit is horizontal, and when one side of the fulcrum is pushed down with a human finger, the vehicle window opens, and the fulcrum is opened. On the other hand, when the other side is pushed down with a finger, the vehicle window closes. In general, when a person accidentally touches the operation unit of the switch (when a pressing force is applied), the switch is operated (erroneously operated) against the will of the person, and the controlled device is not operated by the person. It may work against your will. However, in the above-described conventional example, since the upper surface of the operation unit is held at the neutral position in a symmetrical state so that the upper surface is horizontal, how to touch the operation unit (how to apply a pressing force)
This could cause the switch to malfunction on either side. [0006] In particular, in the case of a power window switch, when the user leans out of the window, the user may touch the location of the switch, and the switch may malfunction in the direction in which the window closes. Dangerous situations, such as pinching of the body and neck, occurred. SUMMARY OF THE INVENTION [0007] The present invention relates to a switch button corresponding to two operations of pushing and pulling a switch button with a human finger.
A switch device that operates, and even if the switch is accidentally touched and the switch is operated (malfunction) against the will of the person, it will malfunction only in one direction, thus ensuring safety against erroneous operation. The purpose is to provide a high switching device. [0008] The invention according to claim 1 of the present invention is provided so as to be exposed on the upper surface of a case, and is usually provided with a medium. A switch button to be provided and that of the switch button provided inside the case. In the switch operation, the upper surface of the switch button is related to a direction substantially orthogonal to the axial direction of the shaft support, and the distance between one end and the fulcrum is the other end and the fulcrum. And the switch button And features. The invention according to claim 2 of the present invention combines the configuration of the invention according to claim 1 with
On the other side of the switch button, as it is difficult to operate with a human finger,
The switch device is characterized in that a gentle roundness is formed on the upper surface of the switch button. [0010] The third aspect of the present invention is directed to the configuration of the first or second aspect of the present invention. It is a power window switch configured to be controlled. According to the present invention, the upper surface (surface) of the switch button is arranged such that one side of the switch button has a longer distance to the fulcrum and the other side has a shorter distance to the fulcrum. )
Is formed, so that when a pressing force is applied to the switch button, the switch button is easily tilted so that one side (the side with a longer distance from the fulcrum) is lowered. Further, the switch button is provided on one side (the side having a long distance from the fulcrum) of the person's finger. Since the switch button has a gentle round shape on the upper side of the switch button so as to be difficult to operate with a human finger (on the side closer to the fulcrum), the one side is more likely to be lowered. One side will not go up, contrary to the wishes). Therefore, for a mechanical operation that may cause a danger if the operation is not performed with care, a switch in which the one side of the switch button (the side with a long distance from the fulcrum) goes up. If it is made to correspond to the tilting operation of the button, even if a person accidentally touches the switch button and the pressing force is applied to the switch button (falls down), the switch button is on one side (the side that is farther from the fulcrum) Is tilted down so that potentially dangerous mechanical operations are not performed, there is no danger, and safety against erroneous operations is increased. In particular, in the power window switch, the switch operation in a direction in which one side of the switch button (the side with the longest distance from the fulcrum) is lowered is used to open the window. If you set the switch operation to the direction where the distance from the (longer distance to the longer side) rises in accordance with the closing of the window, the window will open if you accidentally touch the switch button or get weight. Even if there is, the window will not close,
Dangerous situations such as pinching of the body or neck between the window frame and the glass can be reliably prevented, and the safety against erroneous operation is increased. Furthermore, if the other side of the fulcrum of the switch button is formed with a gentle round on the upper surface of the switch button so that it is difficult to operate with a human finger, the switch button from the other side can be formed. Erroneous operation of the switch device can be completely prevented, and safety against erroneous operation of the switch device can be further improved. An embodiment of the present invention will be described below in detail with reference to the drawings. The drawing shows a 4-door type vehicle-mounted power window switch.

Are formed, and the contact pieces 29 to 33, 29a are exposed at the same pitch in parallel with the concave surfaces in the concave portions 35, 35, and a pair of left and right movable contacts 24 described later is formed on each of the exposed surfaces. , 24 correspond to the sliding contact. In this case, three contact pieces 29 to 31 as the first contact pattern P1 are located in the left recess 35 partitioned by the partition wall 34, and the third contact piece 29 to 31 is located in the right recess 35. Three contact pieces 32, 33, 29a as two contact patterns P2 are located, and movable contacts 24, 24 to be described later are in contact with the contact patterns P1, P2 independently of each other. Of the six contact pieces 29 to 33 and 29 a, the contact pieces 29 and 29 a on both sides are integrally formed and electrically connected, and these are ON contact pieces 29 and 29 of each contact pattern P 1 and P 2. 29a, the two contact pieces 30, 31 on the first contact pattern P1 side parallel to the inside of each of the ON contact pieces 29, 29a are set as a common contact piece and an OFF contact piece, and the second contact pattern Both contact pieces 32 and 33 on P2 side are OFF
The contact piece and the common contact piece are set. As shown in FIG. 5, each of the common contact pieces 30, 33 is connected to a DC motor M for driving a window regulator via a lead wire, and the other contact pieces 31, 32,
Similarly, 29a is connected to the positive and negative electrodes of the vehicle-mounted battery via lead wires. The above-mentioned movable contact 24 is provided in a W shape as shown in FIG. 4. A swing permitting projection 36 is provided at the center of the upper surface of the W shape, and the contact patterns P 1 and P 2 are arranged in parallel on the lower surface. A W-shaped bottom contact portion is provided that straddles both sides of the contact piece that is contacted at two right and left points. The movable contacts 24 are provided in a pair on the left and right sides, and
The sliders 25, 25, which will be described later, slide and operate in the recesses 35, 35 in the longitudinal direction thereof. As a result, the one movable contact 24 is connected to the contact pieces 29 to 3 on the first contact pattern P 1.
1 and the other movable contact 24 is a contact piece 32 on the second contact pattern P2,
Between 33 and 29a, the contact corresponding position is independently variably operated, and the current flow direction is switched between forward and reverse. The above-mentioned slider 25 is accommodated in the respective recesses 35, 35 of the switch case 23 so as to be slidably accommodated in a pair on the left and right sides, and has a lower surface for pressing and supporting the above-mentioned movable contact 24. An engagement recess 37 is formed, and furthermore, at a central portion in the engagement recess 37,
A projection corresponding hole 38 into which the above-mentioned swing allowance projection 36 is fitted is formed with a concave portion. The projection corresponding hole 38 is provided in a spherical concave shape corresponding to the spherical surface of the swing allowable protrusion 36, so that the movable contact 24 is supported at one point, and the swing allowable protrusion 36 is
Is pivoted in any direction with the fulcrum as a fulcrum, and slides, and a smooth sliding contact response action is performed. By the way, between the wall surfaces of the sliders 25, 25 on the side opposite to the partition wall 34 and the inner wall surface of the switch case 23, slider return springs 26, 26 are interposed in a compressed state, and the sliders 25, 25 are centered. The position of the urged and moved position is set to the OFF position, and the first contact pattern is opposed to the urged force. The sliding position where the slider 25 on the P1 side is slid is set to the position corresponding to the ON contact on the positive electrode side, and the second contact pattern P
The sliding position where the slider 25 on the second side is slid against the urging force is set to a position corresponding to the ON contact on the opposite pole side. For this reason, the sliders 25, 25 are normally urged by the slider return springs 26, 26, and are respectively at the neutral OFF position. From this state, the switching operation is performed to either the forward position or the reverse position. Is done. Further, after the sliding operation of the slider 25, the slider 25 is automatically returned to the original position by receiving the urging force of the slider return spring 26, so that the switching operation becomes extremely easy. Further, fitting recesses 39, 39 for fitting leaf springs 27, which will be described later, are formed on the upper surfaces of the sliders 25, 25, and a slider operating rod 21 of a switch button is provided at the center of the upper surface. Slide shafts 40, 40 are provided so as to cope with the above. The above-mentioned leaf springs 27, 27 are provided in a concave shape,
9, a through hole 41 is formed in the center of the flat shape of the leaf spring 27 and penetrates the slide shaft 40, and an arc-shaped protrusion 42 is formed in the center bent portion to protrude. The arc-shaped projection 42 is engaged with a tactile response portion 43 of the switch cover 28 described later. The above-described switch cover 28 is provided in a box shape with one surface opened, and a pair of left and right touch-sensitive portions 43, which correspond to the above-described arc-shaped protrusions 42, 42 in the sliding direction of the one surface of the box shape. 43 is engraved and engages when the above-mentioned arc-shaped projection 42 slides on the tactile corresponding part 43 to make the positioning of the slider 25 accurate and slide to switch the polarity of the switch. The operation feeling at the time of vigorous engagement at this time is transmitted to the above-mentioned switch buttons 14 to 18 via the elastic action of the leaf spring 27. Further, slide holes 44, 44 for allowing the above-mentioned slide shafts 40, 40 to protrude upward are formed in the opposing wall surface of the switch cover 28, and connecting pieces 45 are vertically provided on the outer periphery. The fitting recesses 46 formed on the inner surfaces of the connecting pieces 45.
.. Correspond to fitting protrusions 47 formed on the outer periphery of the switch case 23, so that the switch cover 28 covers the switch case 23 with the leaf spring 27 slightly compressed from above. , Are integrally connected to the switch case 23. The lower end of the above-described slider operation rod 21 is interposed between the slide shafts 40 projecting to the left and right, and one of the sliders is moved by the movement of the slide operation rod 21 located at the intermediate portion in the sliding direction. The slider 25 on the same side is slid via the shaft 40. [0038] The vehicle-mounted power window switch configured as described above is provided exclusively for the driver. When an arbitrary switch button 14 to 17 is operated from the driver's seat, a window corresponding to the input signal of the switch button is operated. The opening and closing operation of the window is performed, and the opening and closing operation of the window is locked and unlocked by pressing the fifth switch button 18 as necessary. Normally, in each of the internal switch units 22... Corresponding to the switch buttons 14 to 18, the movable contacts 24 at the positions of the contact patterns P 1 and P 2 are represented by solid lines in FIG. As shown by, it is set to an OFF position that is not in contact with the ON contact pieces 29 and 29a. When the window is to be lifted and closed from the OFF state, the slider 25 on the first contact pattern P1 side is slid via the switch button, so that the movable contact 24 sliding with the slider 25 is moved. As shown by the imaginary line in FIG. 5, one of the ON contact pieces 29 and the common contact piece 30 are in contact with both of them, and the other movable contact 24 is
It does not slide at the OFF position. As a result, the current flow is 29a → 29 → 24 → 30 → M → 33 → 24 → 3
2, the motor M for driving the window regulator is driven to rotate forward, and the operation of raising and closing the window is performed. When the operation force of the switch button is released, the movable contact 24 integrated with the slider 25 automatically returns to the original OFF position by the urging force of the slider return spring 26. Further, when the window is opened and lowered, the slider 25 on the second contact pattern P2 side is slid via the switch button, so that the movable contact 24 sliding with the slider 25 is virtually shown in FIG. As shown by the line, the other ON contact piece 29a and the common contact piece 33 are in contact across both of them, and the other movable contact 24 is not slid at the OFF position as it is. As a result, the current flows in the order of 29a → 24 → 33 → M → 30 → 24 → 31, whereby the motor M for driving the window regulator is driven to rotate in the reverse direction, and the operation of lowering and opening the window is performed. . Then, by releasing the operation force of the switch button, the movable contact 24 integrated with the slider 25 returns to the original OFF position. As described above, at the time of the non-switching operation, the pair of left and right sliders 25, 25 corresponding to the two sets of contact patterns P 1, P 2 are in a state of being biased to the OFF position. When one of the sliders 25 is slid to the non-biasing side via the operating rod 21, the state is switched from the OFF position to the contact corresponding state of the ON position on the positive electrode side,
When the other slider 25 is slid toward the non-biasing side, the state is similarly switched from the OFF position to the contact corresponding state of the ON position on the opposite pole side. Therefore, at the time of the switching operation, the switching operation can be performed by selecting the contact corresponding side of the ON position of either the forward or reverse polarity from the neutral OFF position where the operability is easy. The plurality of switch units 22 described above are provided for each of the switch buttons 14, 15, 16, and 17 exposed on the upper surface of the operation cover 12. At the time of attachment, the performance of the above-described switch unit 22 can be checked independently. In the above-described embodiment, in each of the switch buttons 14 to 17 and the switch unit 22 corresponding to them, even if the switch buttons 14 to 17 are formed slightly larger in terms of operability, each switch unit 22 has a lower surface. , The occupied area is reduced in a plane area. Further, since the slider shaft 40 of the switch unit 22 extends in the lateral direction of the unit 22, there is no component (the main body of the switch unit 22) below the slider operating rod 21, and the switch button 14 17 to switch unit 2
2 can be provided close to the bottom surface. As a result, the switch buttons 14 to 17 and the switch unit 22 occupy a small area, and the upper and lower thicknesses of the switch buttons 14 to 17 and the switch unit 22 remain the same as those of the related art while maintaining good operability. The thickness of the power window switch can be reduced, and the power window switch for a vehicle can be made thin and small and compact as a single unit. In addition, when the switch buttons 14 to 17 are unexpectedly touched, there is an effect that the end on the long side with the fulcrum 16b is easily pushed down. If the mechanical operation is performed by tilting the switch buttons 14 to 17 in the direction in which the end on the long side with the fulcrum 16b rises, even if the switch buttons 14 to 17 are touched unexpectedly, , Fulcrum 16b
Is tilted so that the end on the longer side of the distance is depressed, so that a potentially dangerous mechanical operation is not performed, and the safety against malfunction is enhanced. In correspondence between the configuration of the present invention and the above-described embodiment, the switch device of the present invention is formed by the switch buttons 14 to 17 of the embodiment and the switch unit 22 provided corresponding thereto. The case corresponds to the switch device, and similarly, the case corresponds to the operation cover 12 and the base 13 in the same manner, but the present invention is not limited to only the configuration of the above-described embodiment. Further, in the above-described embodiment, the in-vehicle power window switch for four doors is exemplified, but it is needless to say that the present invention may be applied to a two-door power window switch.
