Description

[Detailed Description of the Invention] The present invention relates to an operation switch for opening and closing a ceiling window of a vehicle, and an object of the present invention is to facilitate the operation of the switch when opening and closing the ceiling window.

Some vehicles have overhead windows installed on their roofs that can be opened and closed using an electric motor by operating a switch. Conventionally, the operating switch used in this type of case has been a simple on/off type, which has the disadvantage of making the switch operation complicated. In other words, if it is a return type operation switch, the operation member must be kept in the operating state when the ceiling window is fully opened, for example, and if it is a lock type, the operation member must be kept in the operating state when the ceiling window is slightly opened or closed. The member had to be manipulated twice in quick succession.

The present invention is aimed at solving such problems of the prior art, and is characterized in that a common contact 36 and a forward rotation contact 37 and a reverse rotation contact 38 on either side of the common contact 36 are provided on a fixed plate 41, and an operating member 39 having operating surfaces 45, 46 for forward and reverse rotation is provided so as to be capable of being rotated forward and backward around a support shaft 47, and a movable contact 35 is provided between the fixed plate 41 and the operating member 39, and the movable contact 35 rotates between the forward rotation contact 37 or the reverse rotation contact 38 with the common contact 36 as a fulcrum.
and a neutral state in which it does not contact any of the contacts.
The movable body 40 is provided with a protrusion 50 protruding toward the side and biased in the protruding direction by a spring 51, and the movable body 40 is provided with a cam surface 42 against which the protrusion 50 slidably contacts so that when the operating member 39 is rotated to the first-stage operating position A, the movable body 40 is rotated so that the movable contact 35 contacts the forward rotation contact 37 or the reverse rotation contact 38, and when the operating force is released, the operating member 39 and the movable body 40 are rotated back to their neutral state, and a pair of engaging recesses 43, 44 with which the protrusion 50 releasably engages when the operating member 39 is operated beyond the first-stage operating position A to the second-stage operating position B, thereby holding the operating member 39 and the movable body 40 in the rotated position.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. In FIG. 1, 1 is a vehicle, 2 is a seat, 3 is a dartboard, and 4 is a steering wheel. Reference numeral 5 denotes a roof, and a ceiling window 8 consisting of an opening 6 and a sliding roof 7 is provided at the front end of the roof. As shown in FIG. 2, the sliding roof 7 has four guide pieces 9 on the front, back, left and right sides, and each of the left and right guide pieces 9 connects to a pair of guide rails 10 built into the roof 5 on both sides of the opening 6. The sliding roof 7 is slidably supported on the other hand, and the sliding roof 7 is slidable back and forth to open and close the opening 6.
A flexible cable 11 having a spiral strip is connected to each guide piece 9 on the front side, and each flexible cable 1
1 are guided to a position in front of the opening 6 through the guide tube 12 and are engaged with the gears 13, respectively.

As shown in FIG. 3, the gear 13 is fixed to the upper end of a vertical shaft 15 that is rotatably inserted into a gear case 14, and the vertical shaft 15 is connected to a slip clutch 16, a worm gear 17, a worm 18, etc. It is interlocked and connected to the electric motor 19 via. The worm gear 17 is fitted around the vertical shaft 15 so as to be relatively rotatable, and a slip clutch 16 is provided to connect the worm gear 17 and the vertical shaft 15. The slip clutch 16 has a pair of clamping parts 22 and 23 arranged to sandwich the worm gear 17 from above and below via shoes 20 and 21, and one clamping plate 22 is attached to a collar part 24 fixed to the vertical shaft 15. On the other side of the clamping plate 23, a disc spring 25, a spring receiving plate 26, a collar 27, a washer 28, etc. are fitted onto the vertical shaft 15.
It is tightened in the axial direction by a screw 30 that is screwed into a female screw hole 29 formed at the lower end of. The screw 30 is for torque adjustment, is provided so that it can be operated from the indoor side, and is also detachable. A groove 31 for engaging a tool such as a screwdriver is formed at the lower end of the vertical shaft 15, so that in the event of a failure of the electric motor 19, the sliding roof 7 can be opened and closed manually.

As shown in FIG. 4, the electric motor 19 is connected to a DC power source 34 via an overcurrent relay 32 and an operating switch 33, and can be controlled in forward and reverse directions by switching the operating switch 33. The operation switch 33 electrically includes one pair each of a movable contact 35, a common contact 36, a forward rotation contact 37, and a reverse rotation contact 38.
It is configured as shown below. That is, in addition to the above-mentioned contacts, the operating switch 33 includes an operating member 39, a movable body 40, a fixed plate 41, a case 53, etc., as shown in FIG. The movable body 40 and the fixed plate 41 are made of an insulating material, and a movable contact 35 is provided on the upper surface of the movable body 40, and a cam surface 42 and engagement recesses 43, 44 on both sides thereof are provided on the lower surface. Fixed plate 4
1 is provided with a common contact 36, and a forward rotation contact 37 and a reverse rotation contact 38 are provided to sandwich the common contact 36, and the common contact 36 can be freely engaged and detached from a pair of recesses formed in the center of the movable contact 35. It also serves as a fulcrum member for swinging the movable body 40. Operation member 3
9 has two operation surfaces 46 formed in an inverted V shape on the lower surface, and is swingably supported by the case 53 by a support shaft 47, and this operation member 39 rotates forward and reverse around the support shaft 47. At any given time, two-stage operation is possible between a first-stage operating position A and a second-stage operating position B. Operation member 3
A protrusion 48 is formed at the center of the upper surface of the protrusion 9 , and a protrusion 50 is fitted into a hole 49 formed in the protrusion 48 while being urged outward by a spring 51 .
The cam surface 42 with which the protrusion 50 comes into slidable elastic contact is,
When the operating member 39 is operated to the first stage operating position A and the movable body 40 is swung to bring the movable contact 35 into contact with the contact 37 or 38, if the operating force on the operating member 39 is released, the spring 51 is released. The shape is such that the operating member 39 and the movable body 40 can be returned to their original positions by elastic force, and the engaging recesses 43 and 44 engage the protrusion 50 when the operating member 39 is operated to the second operating position B. Together, the operating member 39 and the movable body 40
It is for locking.

Next, the effect will be explained. It is now assumed that the sliding roof 7 of the ceiling window 8 is in the fully open position, that is, on the rear end side of the guide rail 10. Therefore, when closing the sliding roof 7, the operating member 39 of the operating switch 33 located at the front end of the roof 5 is operated. Then, the movable contact 35 of this operating switch 33 connects to the reverse contact 38 side, so the electric motor 19 rotates in the reverse direction, and the vertical shaft 15 rotates via the worm 18, worm gear 17, and slip clutch 16, and the The gear 13 pulled each flexible cable 11 forward,
Therefore, the sliding roof 7 slides along the guide rail 10 in the direction indicated by arrow a. When the sliding roof 7 reaches the front end and is completely closed, the slip clutch 1 connecting the worm gear 17 and the vertical shaft 15
6, slippage occurs and the electric motor 19 idles. At this time, an overcurrent flows through the electric motor 19, so the overcurrent relay 32 operates, automatically opening the power supply circuit of the electric motor 19, and stopping the electric motor 19. This also applies when the sliding roof 7 is closed while the human body is exposed through the opening 6, and therefore it also functions as a safety feature when closed. After closing the sliding roof 7, the operation switch 33 is returned to its original position.

Each part of the operation switch 33 is normally in the state shown in FIG. Therefore, when closing the operation member 39 as described above, if the operation surface 46 of the operation member 39 is pressed in the direction of the arrow b,
The operating member 39 moves around the support shaft 47 in the direction of arrow b.
Rotate to stage operation position A. At this time, the protrusion 50
slides on the cam surface 42 by the elastic force of the spring 51 and presses the movable body 40, so the movable body 40 rotates in the direction of arrow c using the common contact 36 as a fulcrum, and the movable contact 35 Connect the contact 36 and the reversing contact 38 (see Figure 6). When the operating force on the operating member 39 is released from this first stage operating position A, the protrusion 50 slides toward the center on the cam surface 42 by the elastic force of the spring 51, so that the operating member 39
9 returns and rotates around the support shaft 47 in the direction of arrow b,
Then, the movable body 40 returns and rotates in the direction of arrow C so as to straddle both protrusions of the common contact 36, and each part
Return to the state before the operation shown in the figure. Therefore, this first
The operation up to step operation position A is very convenient for inching the electric motor 19.

When the operating member 39 is further pressed and rotated from the first operating position A to the second operating position B, the protrusion 50 crosses the cam surface 42 and engages with the engagement recess 44, and the operating member 39 As shown in FIG. 7, the movable contact 35 can maintain the so-called on state connected to the common contact 36 and the reversing contact 38 even if the operating force is released and the sliding roof 7 is completely locked as shown in FIG. Very convenient to operate when fully open or fully closed. When returning the operating member 39 to its original position, it is sufficient to press the operating surface 45 on the opposite side, and as a result, the protrusion 50 separates from the engagement recess 44 while resisting the spring 51, resulting in a process similar to that described above. It returns to its original state depending on the action.

The operation and operation when opening the ceiling window 8 are the reverse of those described above, and the explanation thereof will be omitted.

In addition to the overcurrent relay 32, a limit switch for detecting opening and closing of the sliding roof 7 may be provided and incorporated into the power supply circuit of the electric motor 19.

As described in detail in the embodiment below, in the present invention, the fixed plate 41 has a common contact 36 and normal rotation contacts 37 on both sides thereof.
and a reverse rotation contact 38, and an operating member 39 having operating surfaces 45, 46 for forward rotation and reverse rotation is provided so as to be rotatable in the forward and reverse directions around a support shaft 47, and between the fixed plate 41 and the operating member 39. , has a movable contact 35, and has a common contact 36 as a fulcrum.
A movable body 40 is provided so as to be rotatable between an operating state in which the contact point 37 or the reverse rotation contact 38 contacts and a neutral state in which it does not contact any of the contacts. A protrusion 50 that protrudes to the side and is biased in the protrusion direction by a spring 51
The movable body 40 is rotated so that the movable contact 35 comes into contact with the forward rotation contact 37 or the reverse rotation contact 38 when the operation member 39 is rotated to the first stage operation position A, and the operation force is applied to the movable body 40. When the operation member 3 is released,
9 and the movable body 40 to return to the neutral state and rotate, the protrusion 50 slidably contacts the cam surface 42
When the operating member 39 is operated beyond the first stage operating position A to the second stage operating position B, the protrusion 50 is removably engaged to hold the operating member 39 and the movable body 40 in a rotating posture. a pair of engaging recesses 43 for
44, so when opening and closing the ceiling window,
The operating member 39 is moved to the first operating position A according to the opening/closing amount.
and the second operation position B, and the operation is much easier than the conventional switch operation. Furthermore, as mentioned above, since the common contact point 36 is also used as the fulcrum of the movable body 40, it has the advantage of being extremely simple and compact in terms of structure, and can be installed in a vehicle with minimal effort. This is easy if you have the space.
