Abstract

PURPOSE:To improve the freedom for design, by providing a guide member with a guide frame and standing and bringing down a cam arm in association with a slider for lifting a member to be lifted in the captioned device for an automobile sun roof. CONSTITUTION:When a slider 41 moves backwardly on a main guide rail 13 and passes in the vicinity of a guide member 45, a front guide pin 48 turns a cam arm 42 by being guided by a guide groove 46 to cause a standing and bringing-down arm 43 in an inclined state. As a result, the front edge portion of a slide roof 2 is lifted so that it is in a horizontal state and moves backwardly along a guide pin 49. When the slide roof 2 is to be closed, a guide pin 49 is engaged with the guide groove 47 of a guide member 45 to be guided and moves forwardly by bringing down the standing and bringing-down arm 43 while the front edge of the roof is lowered. With this arrangement, any desired position for lifting and lowering operation can be set, whereby the freedom for design is improved.

Description

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

The present invention relates to a slide-type elevating device that is configured to operate in conjunction with the movement of a slider provided movably along a guide rail, and is suitable for elevating and lowering a slide roof in a vehicle sunroof, for example.

[Conventional technology]

As a sliding roof elevating device as described above, there is a conventional technique described in, for example, Japanese Patent Laid-Open No. 59-6131. This is mainly based on a linkage device operated by a cable system for moving and operating the sliding roof.

[Problems to be solved by the invention]

However, in the above-mentioned conventional example, since the lifting device is operated by a cable system for moving the sliding roof, the sliding roof can be raised or lowered only at one limited position such as the start or end point of its stroke, and can be moved at any point during the stroke. There is a problem that it cannot be raised or lowered depending on the position, and there is no freedom in design. Therefore, the present invention provides a slide type lifting device in which the lifting operation position can be set at any position within the stroke of the slider, thereby providing a degree of freedom in design when applied to a sliding roof. The purpose is to

[Means to solve the problem]

For this purpose, the present invention provides: - a slider movable along a guide rail; a tilting arm having a lower end pivotally connected to the slider and an upper end pivotally connected to an object to be lifted and lowered; a cam arm with a guide bin which is pivotally connected to the slider and raises and lowers the tilting arm by rotating at a predetermined angle; The present invention is characterized in that it includes a guide body attached to a guide lug.

[Function] With this means, when the slider moves along the guide rail and passes near the guide body, the guide bin is guided by the guide and body, causing the cam arm to rotate by a predetermined angle. The raising and lowering arm is raised and lowered, and the object to be lifted and lowered which is pivoted to the upper end of the arm is raised and lowered. [Embodiment] Hereinafter, an embodiment in which the present invention is applied to raising and lowering a slide roof of a vehicle sunroof will be described with reference to the drawings. As shown in FIG. 2, a window 11 is opened in the roof 1 of the vehicle, and a sliding roof 2 is provided to open and close the window 11. The slide roof 2 has a shape that fits perfectly into the window 11.

[No. At its front end, a protrusion 32 that fits into a groove 31 formed on the front edge 12 of the window 11 is formed, and these constitute a locking fitting part 3 (see Fig. 1), and a slide roof 2 controls the vertical position of the slide roof 2 with respect to the roof 1 with the window 11 closed. An elevating device with a slider is provided to support such a slide roof 2 so that it can be raised and lowered with respect to the roof 1 and can be moved back and forth. This elevating device includes a sliding front elevating device M4 that is movable back and forth along a main guide rail 13 attached to the vehicle roof 1, and a rear edge 14 of the window 11 of the roof 1.
The rear RIL is engaged with the sub-guide rail 15 placed nearby so that it can move slightly back and forth! The front end of the slide roof 2 as an object to be lifted and lowered is pivoted to the upper end of the sliding front lifting device e4, and the rear lifting device 5 is attached to the upper end of the sliding roof 2 side. The slide roof 2 is moved relative to the roof 1 by engaging the guide rail 21 so as to be relatively movable in the front-rear direction via a slider to be described later.
It can be moved forward and backward. Here, the above-mentioned elevating device will be explained. First, in the sliding 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 pivoted on a slider 41 corresponding to the main guide rail 13. At the same time, one end of the cam arm 42 and the intermediate portion of the tilting arm 43 are pivotally connected via the connecting link 44, so that the tilting arm 43 is raised and tilted in response to rotation of the cam arm 42 by a predetermined angle. As described above, the slide roof 2 as an object to be raised and lowered is pivotally attached to the upper end of such a raising and lowering 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 includes a pair of guide grooves 46 and 47 which are symmetrical in the shape of an inverted eight, whose lower ends communicate with the inside of the main guide rail 13, and whose upper ends are open. Correspondingly, at both ends of the cam arm 42,
Guide bins 48.49 are mounted which slide within the main guide rail 13 and in guide grooves 46,47. However,
The guide bin 49 on the connecting link 44 side is the main guide rail 1
3, the raising/lowering arm 43 lies down substantially parallel to the main guide rail 13, and at this time, the other guide bin 48 positioned forward is located above the main guide rail 13 and the guide body 45 can be engaged with the front guide groove 46 (see FIG. 5(2)). Conversely, when the front guide bin 48 is located within the main guide rail 13, the raising/lowering arm 43 stands up in an inclined state, and at this time, the rear guide bin 49 is positioned as a rear guide in the guide body 45. (See FIG. 5). Note that both the guide bins 48 and 49 are configured such that when the front guide bin 48 engages with the front guide groove 46 and is guided,
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 vice versa (as shown in FIG. 5). , (C)). 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 becomes the sub-guide. When located in front of the rail 15, the raising/lowering arm 53 is configured to stand approximately vertically. FIG. 8 shows an outline of the drive device 6 for operating the front and rear lifting devices 4.5 mentioned above. This electric motor 61 is connected to the sliding front lifting device 4 and the rear lifting device 5 via a cable device 62 having an operating force transmission switching device 7, which will be described later, in the middle. This cable device 62 includes a cable 63 that can slide forward and backward with respect to the sheath, and an electric motor 61
The couple 63 is driven forward and backward based on the rotational driving force of. 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. The driving body 73 and the electric motor 61 are connected to each other, and the front switching slider 71 and the slider 52 of the rear lifting device 5 are connected via a cable 63 of a cable device 62. , electric motor 61
The driving body 73 is reciprocated by the forward and reverse rotations, 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. In addition,
In this embodiment, the rear switching slider 72 is formed as a part of the slider 41 of the sliding front lifting device 4 and serves also as the slider 41 . The front switching slider 71 includes a driver passage 74a formed in the slider body 74 along the longitudinal direction of the main guide rail 13 so that its rear end is open, and this driver passage 74a.
The drive body passage 74
In a, a stopper 7G is biased by a rear spring 75.
is housed in a way that prevents 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 77 is rotated as the stopper 76 moves backward, and can be held in a state in which a corner portion 77a protrudes from one side of the slider 71. In the state,
- The corner portion 77a can be retracted into the cam accommodation recess 74b, and the other corner portion 77b can be projected into the driver passage 74a. With respect to such a switching slider 71, the rear switching slider 72 is configured symmetrically with respect to the front-rear direction of the main guide rail 13, so the description of each part will be omitted using the same reference numerals. On the other hand, the lock-9 in the front and rear switching sliders 71 and 72
= On one side wall of the main guide rail 13 corresponding to the cam 77,
A pair of locking windows 13a and 13b are opened to allow one corner 77a of the locking cam 71 to protrude. The pitch of these locking windows 13a, 13b is determined by the pitch of each locking cam 77, 77 when the front and rear switching sliders 71, 72 are in contact with each other.
It corresponds to the pitch of the locking windows 13a, 1.
3b in the longitudinal direction of the main guide rail 13 is the locking position when the front switching slider 71 moves rearward from the front end of the main guide rail 13 by the movement stroke of the slider 51 of the rear lifting device 5 described above. This corresponds to the position of cam 77. Here, the aforementioned driving body 73 has its engaging portion 73a at the ninth position.
As shown in the figure (f), it is engaged with the front switching slider 71 and set. 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 17, so that the switching slider 7
1 is engaged. In FIG. 10, reference numeral 78 is a cover that covers the upper surface of the slider main body 74, and this cover 78 has a notch 78a through which the neck portion 73b of the driver 73 described above is passed, along the driver passage 74a at the rear end. It is formed by opening the Further, reference numeral 79 denotes a cable terminal bracket, which is appropriately fixed to the slider main body 74 and connects the switching slider 71 and the slider 51 of the rear lifting device 5 via a cable 63. In the above construction, 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. 11), the locking fitting part 3 is fitted, the sliding roof 2 is in the lowered position by the front and rear lifting devices 4.5, and the window 11 of the roof 1 is closed. When the motor 61 is driven forward and backward, the cable device 6
The driver 73 is pulled rearward via the second cable 63. As a result, the front switching slider 71 moves rearward within the main guide rail 13, and at the same time, the slider 51 of the rear lifting device 5 linked via the cable 63 moves rearward within the sub-guide rail 15. In other words, Figure 7 (2)
As shown in (a) to (b), 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 shown in FIG. 9(b), and the locking window 13a matches the position of the locking cam 77. The cam 77 rotates with the corner 77a protruding into the locking window 13a, and the stopper 76 projects into the driver passage 74a to restrict rotation of the locking cam 77. As a result, the locking cam 77 is held with the corner 77a protruding into the locking window 13a, 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 with its rear end raised as shown in FIG. 11 Φ). Corner 7 of locking cam 77 on front switching slider 71
7b retreats from the driver passage 74a, the engaging portion 73a of the driver 73 moves further rearward, and eventually enters the driver passage 74a that is connected to the rear switching slider 72, and the stopper at the back thereof. 76 against the spring 75, engages with the rear switching slider 72, and moves it rearward with respect to the main guide rail 13 (Fig. 9(C), (φ
, see (e)). The backward movement of this switching slider 72, that is, the slider 41 in the sliding front lifting device 4
As the slide roof 2 moves backward, the slide roof 2 moves backward while partially sliding its guide rail 21 on the slider 52 of the lifting device 5, and the locking state of the locking fitting part 3 is released (Fig. 11). (See (C)). When the slider 41 passes near the guide rest 45 on the main guide rail 13, the front guide 48
6, the cam arm 42 moves from > to (C) in FIG.
), the raising and lowering arm 43 stands up in an inclined state, and the front end of the slide roof 2 is lifted. Note that this vertical position can be arbitrarily selected by shifting the position of the guide body 45 in the longitudinal direction of the main guide rail 13. In this way, the slide roof 2 moves rearward relative to the roof 1 at a raised position substantially parallel to the roof 1 with its front and rear ends raised, and eventually opens the bottom 11 of the roof 1 wide (
Figure 11 (2). 0)). 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. That is, when the slide roof 2 is open, the driver 73 at the tip of the cable 63 holds the engaging portion 73a between the corner 77b of the locking cam 77 and the stopper 76, as shown in FIG. The forward extrusion 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 sliding front lifting device 4, the slider 41 moves forward within the main guide rail 13 and closes the sliding roof 2. When the sliding roof 2 is closed to the position shown in FIG. 11 (ψ), the guide bin 4 of the sliding front lifting device 4
9 is guided by the guide groove 47 at the rear of the guide body 45, the raising/lowering arm 43 is brought down, the front end of the slide roof 2 is lowered, and eventually the protruding strip 3 at the front end of the slide roof 2 is lowered.
2 fits into a groove 31 provided in the front edge 12 of the window 11 of the roof 1. In this state, the switching slider 72
The locking cam 77 which is in the position Φ and pushed by the engaging portion 73a of the driver 73 moves its corner 77b into the driver passage 74.
It is rotated so as to be retracted from the position a, and is held at that rotational position as the stopper 76 advances. Subsequently, the engaging portion 73a of the driver 73 moves further forward, and eventually enters the driver passage 74a on the front switching slider 71 side, and the stopper 76
Push against the spring 75 to engage the switching slider 71. Therefore, the switching slider 71 moves forward, and in response, the slider 51 of the rear lifting device W15 moves forward, the raising/lowering arm 53 falls down, and the rear end of the sliding roof 2 is pulled down, causing the window 11 of the roof 1 to move forward. is completely closed by the sliding roof 2. Effects of the Invention As explained above, according to the present invention, when the slider moves along the guide rail and passes near the guide body, the guide bin is guided by the guide body, so that the cam arm rotates by a predetermined angle. As a result, the raising and lowering arm is raised and lowered, and the object to be lifted and lowered, which is pivoted to the upper end of the arm, is raised and lowered. In other words, it moves up and down in conjunction with the movement of the slider, and by setting the position of the guide body appropriately, it can be moved up and down at any position during the stroke of the slider. A degree of freedom in design can be obtained when applied to lifting and lowering. In addition, the structure is simple because it mainly consists of a slide incorporating a tilting arm and the like and a guide body.
