Abstract

PURPOSE:To open the window of a slide roof type sun-roof widely, by releasing locking by moving the window backwardly with its rear portion lifted upwardly when the window is to be opened, then moving it backwardly in a horizontal state with its front portion lifted upwardly and operating it reversely when the window is to be closed in the captioned slide roof type roof. CONSTITUTION:When a motor is driven normally and reversely, an operating force transmission change-over unit is actuated through a cable for causing the slider of a rear lift unit 5 to move backwardly in a guide rail 15 and a standing arm 53 to stand to lift the rear portion of a roof 2 upwardly. In association with this operation, a front lift unit 4 begins to retract for causing the locking of a lockingly engaged portion 3 to be released. Then, the slider of the front lift unit 4 receives action from a guide member 45 for allowing a cam arm 42 to turn for making the roof 2 horizontal by lifting its front portion. The roof 2 moves backwardly in the horizontal state for opening a window 11. When the window 11 is to be closed, the procedure is effected reversely. With this arrangement, the window can be opened widely and its outside appearance can be improved.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a sunroof for a vehicle that includes a sliding roof that opens and closes a window provided on the roof of a vehicle body.

[Conventional technology]

Conventionally, regarding vehicle sunroofs, for example, Japanese Patent Application Laid-Open No. 59
There is a prior art described in Japanese Patent No.-6131. In this system, a sliding roof, which is provided on the vehicle body roof and is configured to be movable back and forth in order to open and close the window, is driven back and forth via a cable to open and close the window.

[Problems to be solved by the invention]

However, in the above-mentioned embodiment, when the window is opened, the sliding roof moves backward in a tilted position with only the rear end raised, which interferes with the rear edge of the window and prevents a sufficient stroke. There are problems in that it cannot be opened wide and the rear end of the sliding roof jumps up onto the roof, giving it a bad appearance. Therefore, this invention makes it possible to hear the numbered windows installed on the roof sufficiently, looks good, and also allows the sliding roof to be held securely without rattling when the window is closed. Another object of the present invention is to provide a sunroof for a vehicle in which the sliding roof for opening and closing the window can be driven with a simple device configuration.

[Means for Solving the Problems] For this purpose, the present invention provides a vehicle equipped with a sliding roof that is movable back and forth with respect to the roof to open and close a window provided on the roof of the vehicle body. In the sunroof for a car, the sliding roof is located on the same plane as the roof, and is raised and lowered from a lowered position where the window is closed to a lowered position facing the roof, and has a slider material so that it can be moved back and forth with respect to the roof. A locking fitting part is provided between the front end of the slide roof and the front edge of the window to position the sliding roof in a lowered position, and the lifting device is supported on the vehicle body at the front and back sides via a lifting device. Single via cable
A drive device having one drive source is connected, and a cable operating force is transmitted in the middle of the couple in the order from the rear lifting device to the front lifting device when opening the window, and in the reverse order when closing the window. This device is characterized by being provided with an operation force transmission switching device that transmits the tour-pull operation force. [WJllll With such a means, when opening and closing the window, the sliding roof first assumes a tilted position with its rear end raised, and then moves rearward to release the locking state of the locking fitting part. Furthermore, the front end portion is lifted and moved rearward with respect to the roof to a raised position substantially parallel to the roof. Further, when the window is closed, the sliding roof moves forward relative to the roof and lowers its front end to lock the locking fitting portion, and then lowers its rear end. [Example] The present invention will be specifically described below with reference to an example shown in the drawings. FIG. 2 shows the roof part of a vehicle to which this invention is applied,
A window 11 is opened in the roof 1, and the sliding roof 2 is moved to open and close the window 11. The slide roof 2 has a shape that fits perfectly into the window 11, and has a protrusion 32 bored in its front end that fits into a groove 31 formed in the front edge 12 of the window 11, and is engaged with the groove. A locking fitting part 3 is constructed (see FIG. 1) to regulate the vertical position of the slide roof 2 with respect to the roof 1 when the slide roof 2 closes the window 11. An elevating device with a slider is provided to support such a slide roof 2 so that it can be raised and lowered relative to the roof 1 and can be moved back and forth. This elevating device includes a front elevating device 4 that is attached to the vehicle roof 1 and can be moved back and forth along main guide rails 13, and a sub-guide rail 15 that is arranged near the rear edge 14 of the window 11 of the roof 1. The front end of the slide roof 2 is pivotally attached to the upper end of the front elevating device 4, and the rear elevating device 5 is engaged with the rear elevating device 5 so as to be able to move freely back and forth. The slide roof 2 is movable back and forth with respect to the roof 1 by engaging a guide rail 21 with a mounting number attached thereto so as to be relatively movable in the front-back direction via a slider to be described later. Here, the above-mentioned elevating device will be explained. First, in the front lifting device 4, as shown in FIG. 3, the middle part of a bell crank-shaped cam arm 42 and the lower end part of a tilting arm 43 are respectively pivotally connected to a slider 41 corresponding to the main guide rail 13. At the same time, one end of the cam arm 42 and the tilting arm 4
3 is pivotally connected via a connecting link 44, so that the raising/lowering arm 43 is raised and lowered in response to the rotation of the No. J arm 42 by a predetermined angle. As described above, the slide roof 2 is pivotally attached to the upper end of such a tilting arm 43. A guide body 45 is integrally formed near the front end of the main guide rail 13 so as to rotate the cam arm 42 in accordance with the movement of the slider 41, projecting upward (see FIG. 4). The guide body 45 has a reverse V-shape with front and rear symmetry, and has a pair of guide grooves 46 and 47, the lower ends of which communicate with the main guide rail 13, and the upper ends of which are open. Correspondingly, guide pins 48° 4 are provided at both ends of the cam arm 42 to slide within the main guide rail 13 and guide grooves 46 and 47.
9 is installed. Therefore, the position of the guide bin 49 on the connecting link 44 side within the main guide rail 13 is as follows:
The raising/lowering arm 43 is brought down substantially parallel to the main guide rail 13 , and the other guide bin 48 located in front of the main guide rail 13 is located above the main guide rail 13 and is engaged with the guide groove 46 in the front of the guide body 45 . (see Figure 5i)). On the other hand, when the front guide bin 48 is located within the main guide rail 13, the tilting arm 43 stands up in an inclined state, and at this time, the rear guide bin 49 is attached to the guide body 45. (see FIG. 5 Φ)). Note that both guide bins 48 and 49 are guided when the front guide bin 48 engages with the front guide @46.
The positional relationship is set so that the rear guide bin 49 escapes from the main guide rail 13 and passes through the rear guide groove 47, and operates in the same manner in the reverse case (see Fig. 5). ), see Haku). Next, the rear lifting device 5 has a slider 5 corresponding to the sub-guide rail 15 on the roof 1 side, as shown in FIGS. 6 and 7.
1 at the lower end and a slider 52 corresponding to the guide rail 21 on the slide roof 2 side at the upper end. The guide bin 55 attached to the middle part of the raising/lowering arm 53 is slidably fitted into the backward-sloping guide groove 56 formed in the guide body 54, so that the slider 15 at the lower end is moved. When located in front of the sub-guide rail 15, the raising/lowering arm 53 is configured to stand approximately vertically. FIG. 8 shows an outline of the drive device 6 that operates the front and rear lifts @4.5 mentioned above, and there is a power supply at a location under the roof 1 behind the window 11 installed on the roof 1. [IJ'E

2 to the anterior lifting device 4 and the rear gastric lowering @5. This turret device 62 is equipped with a cable 63 that can slide forward and backward with respect to the sheath, and an electric motor 6
The cable 63 is driven forward and backward based on the rotational driving force of 1. As shown in FIGS. 9 and 10, the operating force transmission switching device 7 includes a pair of front and rear switching sliders 71 and 72 that are slidable within the main guide rail 13, and a drive that engages with either one of these sliders. A cable device j62 is provided between the drive body 13 and the electric motor 61, and between the front switching slider 71 and the slider 51 of the rear lifting device 5.
The electric motor 6
The driving body 13 is reciprocated by the forward and reverse rotation of 1, and as the front switching slider 71 moves back and forth, the slider 51 of the rear lifting device 5 is driven back and forth. Note that in this embodiment, the rear switching slider 12 is formed as a part of the slider 41 of the front lifting device 4 and serves also as the slider 41 . The front switching slider 11 includes a driver passage 74a formed in the slider body 14 along the longitudinal direction of the main guide rail 13 so that the rear end thereof is open, and this driver passage 74a.
The drive body passage 74
A stopper 76 biased by a rear spring 75 is housed inside a to prevent it from coming out. A locking cam 77, which has a substantially right triangular shape in plan view, is pivotally mounted to the cam housing recess 74b so as to be freely rotatable around the right angle portion thereof. This locking cam 17 is rotated as the stopper 76 moves backward, and can be held in a state in which the -corner 77a protrudes from one side of the slider 71. In the state,
- The corner portion 77a can be retracted into the cam accommodation recess 7Jb, and the other corner portion 77b can be projected into the driver passage 74a. Since the rear switching slider 12 is configured symmetrically with respect to the switching slider 71 with respect to the front-rear direction of the main guide rail 13, the explanation of each part will be omitted using the same reference numerals. On the other hand, on one side wall of the main guide rail 13, corresponding to the locking cam 17 that is connected to the front and rear switching sliders 71 and 72, there is a pair of locking windows that allow one corner 77a of the locking cam 77 to protrude. 13a and 13b are open. The pitch of these locking windows 13a, 13b corresponds to the pitch of each locking cam 77, 77 when the front and rear switching sliders 71, 72 are in contact with each other.
The open [] position in the longitudinal direction of the main guide rail 13 in b is the moving stroke number of the slider 51 of the rear lifting device 5 described above, and the front switching slider 71 is located at the rear from the front end of the guide rail 13. This corresponds to the position of the locking cam 77 when the locking cam 77 is moved to the position shown in FIG. Here, the aforementioned driver 73 moves the child engaging portion 73a to the ninth position.
J shown in Figure i> is set by engaging the front switching slider 71. That is, the engaging portion 73a is inserted into the driver passage 74a and held between the stopper 76 and the corner portion 77b of the locking cam 77, so that the switching slider 7
1 is engaged. J3, in Fig. 10, the symbol @78 is the slider body 74.
This cover 78 covers the
The cut 78a passes through the neck portion 73b of the driver 73 described above.
However, the driver passage 74a 1. : It is formed with the rear end open along the line. Also, reference numeral 79 is a removable terminal bracket, which is appropriately identified on the slider body 74 and connects the switching slider 71 and the slider 51 of the rear lifting device 5 via a couple 63. In the above configuration, the slide roof 2 is opened and closed by appropriately rotating the electric motor 61 shown in FIG. 8 in forward and reverse directions. Now, as shown in FIG.
When the electric motor 61 is driven in forward and reverse directions when the electric motor 61 is in the lowered position and the window 11 of the roof 1 is closed, the driving body 73 is pulled rearward through the couple 63 of the couple device 62. This causes the front switching slider 71 to move backward within the main guide rail 13, and at the same time the cable 6

As shown in FIGS. 0 to Φ), the raising/lowering arm 53 stands up substantially vertically, and the rear end portion of the slide roof 2 is lifted. At this time, the front switching slider 71 reaches the position indicated by the peak in FIG. 9, and the locking window 13a matches the position of the locking cam 77. The cam 771 projects its corner 77a into the locking window 13a and rotates once, and the stopper 76 projects into the driver passage 74a to restrict the rotation of the locking cam 77. This causes the locking cam 77 to project its corner 77a into the locking window 13a. : state, and the front switching slider 71 is fixed to the main guide rail 13 (see FIG. 9(C)). That is, the slide roof 2 is held in the 1=state with its rear end raised as shown in FIG. 11). As the corner portion 77b of the locking cam 77 located on the front switching slider 71 retreats from the driver passage 74a, the engaging portion 73a of the driver 73 moves further rearward, and eventually engages the rear switching slider 12. When the driver enters the driver passage 74a, push the stopper 76 at the back against the spring 75, engage the rear switching slider 72, and move it backward relative to the main guide rail 13. Figure 9(c)'

As the slider 41 on the front lifting device 4 moves backward, the slide roof 2 moves rearward while causing the slider 52 of the rear lifting device 5 to open its guide rail 21. The locked state of the locking fitting part 3 is released (see FIG. 11(C)). The slider 41 is a guide body 45 on the three guide rails 13.
When passing nearby, the front guide 48 is guided by the front guide groove 46, and the cam arm 42 rotates as shown in FIGS. 5(b) to 5(C). Stand upright and hold the front end of the slide roof 2.
can be lost. In this way, the sliding roof 2 moves rearward with respect to the roof 1 in a raised position substantially parallel to the roof 1 with its front and rear ends raised, and eventually opens the window 11 of the roof 1 wide (Fig. 11(d), (e) )reference). The closing operation of the slide roof 2 is performed by reversely driving the electric motor 61 in the opposite procedure to the opening operation. When the slide roof 2 is in the open state, the driver 73 at the front end of the cable 63 moves the engaging portion 73a between the corner 77b of the locking cam 77 and the stopper 76, as shown in FIG. 9(e). The forward pushing driving force of the cable 63 is applied to the switching slider 72 via the locking cam 77.
That is, since the signal is transmitted to the slider 41 of the front lift system @4, the slider 41 moves forward within the main guide rail 13 and closes the sliding roof 2. When the slide roof 2 is closed to the position shown in FIG. 11(d), the guide pin 49 of the front lifting device 4 is guided by the guide groove 47 at the rear of the guide body 45.
The raising/lowering arm 43 is lowered, the front end of the slide roof 2 is lowered, and eventually the protrusion 32 on the front end of the slide roof 2 is lowered.
The front edge 12 of the window 11 of the roof 1 is fitted with a groove 31. In this state, the switching slider 12
In the position shown in FIG. As it advances, it is held in its co-moving position. Subsequently, the engaging portion 73a of the driver 13 moves further forward, and eventually reaches the driver passage 74a on the front switching slider 71 side.
The stopper 76 is pushed in against the spring 15 and engaged with the switching slider 71. Therefore, switching slider 1
1 moves forward, and in response, the slider 51 of the rear lifting device 5 moves forward, the raising/lowering arm 53 falls down, the rear end of the sliding roof 2 is pulled down, and the window 11 of the roof 1 slides. It is completely closed by the roof 2. Effects of the Invention As explained above, according to the present invention, when the window is opened, the sliding roof holds both its front and rear ends -1L.
Since the window is moved backward by one angle from the roof at an upper back position substantially parallel to the raised roof, the window can be opened sufficiently wide without interfering with the rear edge of the window installed on the roof. In this state, the sliding roof has a good appearance because the rear end does not jump up and protrude significantly above the roof unlike in the past. Moreover, when the window is closed, the locking and fitting portion regulates the vertical position of the slide roof with respect to the roof, so the slide roof is held without wobbling and the window is reliably closed. Further, since the sliding roof described above is driven by a drive device having a single drive source via a couple, the device configuration is simple.
