Abstract

PURPOSE:To make the movement of a hood as smooth as possible by unifying the joint of the first and the second guide devices almost concentrically with a position regulating device when a board member is moved from the moving position to the storing position. CONSTITUTION:When a board member 20 on which a hood is folded and loaded is moved from the moving position to the storing position, a gearing pin 98 for locking operation is moved to an intermediate position to set the hood to the opening position. As a result, the pin 98 is contacted again to the third projection 74, and the first lever 66 is positioned to the gearing position again. Consequently, at the time when the board member 20 is restored to the storing position from the moving position, the relative position in the up and down direction and in the rail axial direction between the first rail 51 and the second rail 52 is set securely at the specific position by the operation of the locking mechanism 60, even though the alignment of the first rail 51 and the second rail 52 of the guide rail 50 is not completed adequately. The alignment can be carried out highly accurately, consequently.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to canvas tops for automobiles.

(Prior Art) In recent years, as part of responding to the diversification of user needs in automobiles, for example, as disclosed in Japanese Utility Model Application Publication No. 61-30525, an opening formed in the roof panel of the vehicle body can be opened and closed using a hood. A canvas-top vehicle has been proposed that has a two-sided cover to provide an even more open feeling.

By the way, as disclosed in the above-mentioned known example, in this type of canvas top vehicle, when the hood is opened, it is stored and held in a folded state on the rear end side of the roof opening. The rear end portion is covered by the hood in this retracted state, and as a result, there is a problem in that a sufficient sense of freedom cannot be obtained considering the size of the roof opening.

One way to deal with this problem is to movably attach a board member to the rear end of the roof opening, and when the top is stored, the top is placed on this board member and is integrated with the board member. The applicant has already proposed a technology in which the roof opening is moved from the vicinity of the roof opening to another part of the vehicle body and fixed thereon, thereby fully opening the roof opening and improving the sense of freedom when the top is stowed. has been done.

(Problem to be Solved by the Invention) As described above, when the top is placed on the board member and moved when it is stored, the first guide member that guides the movement of the top to the vicinity of the board member. A second guide member is also required to place and guide the canopy on the board member.

However, in this case, since the second guide member moves relative to the first guide member, for example, when the board member is moved from the moving position to a predetermined position at the rear end of the roof opening, this first guide member moves relative to the first guide member. Misalignment is likely to occur at the mating portion of the guide member and the second guide member.

Therefore, the present invention has been made for the purpose of ensuring smooth movement of the top by ensuring alignment of the two guide members in a device equipped with two guide members that are moved relative to each other as necessary. It is.

(Means for Solving the Problems) In the present invention, as means for solving such problems, (1) In the invention of claim 1, an opening formed in a roof panel of a vehicle body is covered with a hood so as to be openable and closable. In the canvas top for an automobile, the hood is movably guided between two positions: a closed position where the opening is closed and an open position where the hood is located at one end of the opening and opens the opening. (1) a guide means disposed below the top in the open position, and with the top placed thereon between a storage position corresponding to the open position of the top and a moving position spaced apart from the storage position; a movable board member; a second guide member provided on the board member and configured to be continuous with an end of the first guide member when the board portion (O) is in a storage position; When the first guide means and the second guide means are moved from the moving position to the storage position, the first guide means and the second guide means are arranged so that the joint U" portions of the first guide means and the second guide means are aligned substantially concentrically.
2. In the invention as claimed in claim 2, the position regulating means in the invention as claimed in claim 1 is arranged so that the board member is It is characterized by comprising a locking mechanism that fixes and locks the board member to the vehicle body side member when it is moved from the moving position to the storage position, The position regulating means includes an actuating piece provided in the sighting part (O),
an engaging member having an engaging portion and attached to the vehicle body side member; a locking member having an engaging portion that engages with the engaging portion of the engaging member and attached to the board member; and the aforementioned engaging member. a hook piece that is provided on the member and engages with the actuating piece during the closing operation of the top to cause the engaging part to engage with the engaging part of the engaging member and maintain the engaged state; The present invention is characterized by comprising a lock release piece that is provided on the locking member and releases the engagement state of the engagement member with the engagement portion during the opening operation of the hood, In the invention of 1, the position regulating means is provided at the rear end of the first guide rail and at the front end of the second guide rail when the board member is set from the moving position to the storage position. It is characterized by comprising an engaging part that engages with the above-mentioned locking part.

(Function) In each invention of the present application, by using such means, when the board member is moved from its moving position to its storage position,
The position regulating means causes the first guide means and the second guide means on the board member side to be aligned substantially concentrically;
Integration of the guide means will be promoted as much as possible.

(Effects of the Invention) Since the canvas top of the automatic 1j of the present invention is constructed like soft earth, it exhibits the following effects.

In the automobile canvas top having the structure according to claim 1, when the board member is moved from the moving position to the storage position, the position regulating means causes the mating portions of the first guide means and the second guide means to become substantially concentric. Since the two guide members are made to match and the integration of the two guide members is promoted as much as possible, the movement of the hood is made as smooth as possible regardless of whether the guide means is a two-part type and is configured to move relative to each other. It will be possible to do it.

Further, when the position regulating means is configured as claimed in claim 2, in addition to obtaining the same effect as in the invention of claim 1, the centering U of the first guide means and the second guide means is Since this is achieved by locking the member and the vehicle body side member, the degree of freedom in arranging the position regulating means is improved.

Further, by configuring the position regulating means as claimed in claim 3, the same effects as in the inventions of claims 1 and 2 can be obtained, and in addition, the locking operation and unlocking operation of the locking mechanism can be performed on the hood side member. Since the operation is performed directly by the actuating piece provided on the top, the operation is reliably linked to the movement of the top.

In addition, as described in claim 4, when the position regulating means is configured,
In addition to obtaining the same effect as in the invention of claim 1, since direct alignment is performed between the first and second guide means that require alignment, for example, this can be done through another member. The alignment accuracy is improved compared to the case where the alignment is performed indirectly.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

28 to 30 show canvas top vehicles equipped with a top 30 according to embodiments of the present invention.

This canvas top vehicle has three features as required, namely, an open L section 10 formed on the roof 2 of the vehicle body 1 by a hood 30, which will be described later, as shown in FIGS. 28, 8, and 11. (corresponds to the opening in the claims)
The opening 10 is closed by folding the canopy 30 onto the rear end of the roof 2 as shown in FIGS. 29 and 9.
A second mode in which the top 30 is opened leaving a part of the rear end thereof, and a second mode in which the folded top 30 is moved onto the trunk lid 8 as shown in FIGS. 30 and 1O to open the entire opening lO. Three modes can be selected, and in particular, in the third mode, a wider open area is secured and a more open feeling of high water quality can be obtained.

Basically, this canvas top car has a front header 3 attached to the roof 2 part of the car body l, as shown in Figure 31.
A roof side opening LOa is surrounded by a pair of left and right roof sight rails 5 and a rear header 4 spanning between the roof sight rails 5. A vertically elongated opening 10 is formed with a rear window opening 10b, and a canvas top assembly Z, which will be described later, is assembled to this opening IO.

The canvas top assembly Z is shown in FIGS. 31 and 32.
As shown in the figures, a base frame 40 (described later)
It has a board member 20 and a hood 30.

Base Frame The base frame 40 is disposed along the periphery of the opening IO of the vehicle body 1, as shown in FIGS. 12 to 24, and is located at the front of the vehicle body 1, as shown in FIG. A front header section 41 corresponding to the header 3, a rear header section 45 corresponding to the rear header 4, a sight rail section 43 corresponding to the roof sight rail 5, a pillar part 44 corresponding to the rear pillar 6, and a rear deck 7 corresponding to the front header section 41. It is integrally constituted by a substantially rectangular frame body having a sliding deck part 42, and a second rail 52 (corresponding to the first guide means in the claims) is attached to the sight rail part 43.43. (Figures 9 to 1t)
(See Figure 13, Figures 31 and 32).

The base frame 40 configured in this way is attached to the vehicle body via brackets 14, 14, etc., as shown in FIG.
The bolt is fastened to the periphery of the opening 10 of the opening 10, but in this case, the entire periphery between the periphery of the opening 10 and the base frame 40 is sealed by a sealing material 15 disposed between the two. . In this case, in the front header 3, the roof sight rail 5, the rear pillar 6, and the deck 7 of the vehicle body 1, the joint flange portions 3a, 5a, 6a on the opening 1O side of the outer panel and the inner panel, which constitute the closed cross section, respectively. , 7 a (see FIGS. 12 to 22) are used as seal flange surfaces of the seal material 15, respectively. Therefore, for example, if the roof sight rail 5 and the end of the rear header 4 are set at the same height at the joint, the joint flange 5a of the roof sight rail 5 at the joint is set at the same height.
is discontinuous at this connection part (that is, the seal flange surface becomes discontinuous), and the sealing material 15 cannot be provided continuously, impairing its sealing performance. If the base frame 4o is attached, the base frame 4o will protrude above the roof site rail 5, which will impair the aerodynamic characteristics and appearance. Therefore, in this embodiment, as shown in FIGS. 16 and 23 to 25, both ends 4a of the rear header 4 are joined to the lower side from the joining flange 5a of the roof sight rail 5. , thereby making the joint flange portion 5a continuous and connecting the base frame 40.
In the attached state, the upper surface of the base frame 40, that is, the upper surface of the sight rail part 43 and the upper surface of the roof sight rail 5 are made as flat as possible, so that the distance between the roof sight rail 5 and the base frame 40 is It is designed to ensure sealing performance and maintain the aerodynamic characteristics and appearance of the vehicle body.

Board member The board member 20 has a canopy 30 placed in a folded state as described later, and is inserted into the opening 4 of the base frame 40.

As shown in FIG. 32, it is composed of a substantially flat plate body, and
On both sides 20a, 20a, second rails 52 and 52 having the same cross-sectional shape as the first rail 51 are provided.
51.51 (see FIGS. 14 and 15).

As shown in FIGS. 8 to 11 and 17, this board member 20 has a rear end portion 20b.
A third panel 33 of the hood 30, which will be described later, is fixedly attached to the hood, and is swung between the rear end of the opening 48 and the trunk lid 8 by a swinging mechanism S, which will be described later, arranged on both left and right sides. It is now possible to move it.

That is, as shown in FIG. 11 and FIG. 26, the swing mechanism S includes a pair of front and rear links, that is, a main link 141 located on the front side and a sub link 14 located on the rear side.
2. The main link 141 has a base end 141a fixed to an output shaft 155 of a drive gear unit 144, which will be described later, and a distal end 141b pivotally attached to the board member 20. Further, the sub-link 142 has its proximal end 142 a pivoted to the base 140 and its distal end 142 b pivoted to the board member 20 . Furthermore, the drive gear unit +44 includes six reduction gears 148 to 153 as shown in FIG.
and a cable drive gear 154, the cable +4 is pushed and pulled by the motor unit 143 (Fig. 26).
5 is converted into rotational force of the output shaft 155 and transmitted to the main link +41. Therefore,
By pushing and pulling the cable 145 by the motor unit 143, the main link 41 swings in the backward direction, and the board member 20 is placed in the storage position at the rear end of the opening 48 (see FIG. 8). 9 and 11) and a moving position located on the trunk lid 8 (
It is possible to move between the positions shown in FIG.

Note that when the board member 20 is set at the moving position,
As shown in FIG. 1O, the board member 20 is placed and fixed on a campus support stand 13 provided on the trunk lid 8. As shown in FIG. Also, in FIGS. 20 to 22, reference numeral 12
The member indicated by is a link cover for preventing the swing mechanism S from being exposed to the outside. Further, the swinging mechanism S is disposed at the pillar portion 44 of the heath plate 40 (see FIGS. 11, 16, and 20 to 22), and the motor unit +43 is located at the base frame 44.
0 (see FIGS. 8 to 11 and 18).

Note that when this board portion 420 is set at its storage position, the second rail 52 attached to the top surface of the board portion 420 is coaxial with the second rule 51 attached to the trail portion 43 of the base frame 40. A series of guide rails 50 are constructed that continue in a shape and span from the front end to the rear end of the opening 48. In this case, it is necessary to match the mating parts of both rails 51 and 52, and therefore this implementation is difficult. In the example, the present invention is applied to provide a position regulating device P, which will be described later, in this mating portion.

The position regulating device (the position regulating device P is a position regulating device P, as described above, when the board member 20 is swung from its moving position and set to its storage position, the board member 20 is connected to the first rule 51 provided on the base frame 40 side. It is a rail for accurately aligning the second rail 52 provided on the member 20 side and integrating it at the matching part, and corresponds to the position regulating means in claim 1 in the claims. , as shown in FIG. 1, a locking mechanism 60 (corresponding to the position regulating means in claim 2.3 of the same), which will be described later, and a fitting mechanism 80 (corresponding to the position regulating means in claim 4), which will be described later. It is equipped with

(Lock Mechanism) When the board member 20 is oscillatedly moved from its movement position to its storage position, the lock mechanism 60 is mainly configured to lock the first rail 51 and the second rail 52 relative to each other in two directions: the rail axial direction and the vertical direction. As shown in FIG.
A second lever 66 and a second lever 6, which will be described later, are provided on the rail 52 side.
7 (both of which correspond to the locking members in claim 3) are provided respectively. This striker 62 (corresponding to the engaging member in claim 3) is located at the rear end portion 51a of the second rule 51.
The second rail 52 is provided via a striker bracket 61 attached to the second rail 52 as shown in FIGS.
The mounting position is set so that it protrudes greatly to the side and is located approximately at the height of the lower surface of the second rail 52.

On the other hand, both the first lever 66 and the second lever 67
A bracket 63 attached to the front end of the rail 52
The first bins 64 are spaced apart from each other in the axial direction of the rail.
and a second bin 65, respectively, so as to be swingably supported. The first lever 66 is connected to the striker 62.
The first protrusion 72 engages with the first protrusion 75 of the second lever 67, which will be described later, to restrict the rotation of the first protrusion 72 in the disengagement direction (in the direction indicated by the arrow). a second convex portion 73;
A first lever 66 that engages with a locking engagement pin 98 (corresponding to the actuating piece in claim 3, see FIG. 4) provided on the front moving device Q to be described later and rotates the second lever 66 in the direction of arrow a. It has three convex portions 74, and is always urged to rotate in the direction of the arrow by a spring 69. Also, the second lever 6
7 is a second protrusion 76 (as defined in claim 3) which engages with the lock operation engagement pin 98 and rotates the second lever 67 in the direction of arrow d, outside the first protrusion 75; (corresponding to a lock release piece), and is constantly urged to rotate in the direction of arrow C by a spring 70. Note that the third lever of this lever 66
The protrusion 74 constitutes a lock piece according to a third aspect of the present invention. Further, this lock bracket 63 is provided with a guide groove 68 into which the lock operation engagement pin 98 is engaged. The size and shape of the lock bracket 63 are set so that it fits inside the striker bracket 61. Further, among the first lever 66 and the second lever 67, the first lever 66 is in a state where its first convex portion 72 is engaged with the striker 62 (hereinafter, the first lever 66 at this time is 66 is referred to as the engagement position), the tip of the third convex portion 74 is located approximately on the lower surface of the guide groove 68, and as shown in FIG. A state in which the first convex portion 72 and the striker 62 are disengaged (hereinafter, the position of the first lever 66 at this time is referred to as the disengaged position)
Here, the dimensions and shape of the third protrusion 74 are set relative to the guide groove 68 so that the third protrusion 74 projects upwardly from the upper surface of the guide groove 68. On the other hand, the second lever 67 is rotated in the direction of arrow C by the spring 70 as shown in FIG. In the engaged state (hereinafter, the position of the second lever 67 at this time will be referred to as the engaged position), the second protrusion 76 protrudes into the guide groove 68, and as shown in FIG. When the portion 76 is located at the groove end of the guide groove 68 (the position of the second lever 67 at this time is referred to as the disengagement position), the first
The dimensions and shape of the convex portion 75 are set relative to the second louver 66 and the guide groove 68 so that the engagement between the convex portion 75 and the second convex portion 73 of the second louver 66 is released.

The lock operation engagement pin 98 is located at the front end of the hood 30 and is driven by a motor unit 160, which will be described later, to open and close the hood 30, and its driving characteristics are as follows. It is set as follows. That is, this lock operation engagement pin 98 is connected to the hood 30 which will be described later
When the opening 48 is in the closed position as shown in the figure, it is located at the front end of the opening 48 as shown in the figure, and the position of the locking engagement pin 98 at this time is referred to as the front end position), When the hood 30 is in the open position where the opening 48 is opened as shown in FIG. 9, it is located near the front end of the rule 51 as shown in FIG. 9 and FIG. (The position of the engagement pin 98 is referred to as the intermediate position)
It looks like this. Therefore, when the top 30 moves between the open position and the closed position, the locking engagement pin 98 moves between the intermediate position and the front end position, and especially when the top 30 is in the open position, the locking engagement pin 98 moves between the intermediate position and the front end position. As shown in FIG. 2, the lock operation engagement pin 98 is located at the groove opening of the guide groove 68 of the lock mechanism 60, and the lock operation engagement pin 98 is located at the groove opening of the guide groove 68 of the lock mechanism 60, and the lock operation engagement pin 98 is located at the groove opening of the guide groove 68 of the lock mechanism 60, and the lock operation engagement pin 98 is located at the groove opening portion of the guide groove 68 of the lock mechanism 60.
This corresponds to the third convex portion 74 of No. 6. Further, when the board member 20 is moved from the storage position to the movement position, the lock operation engagement pin 98 is moved further rearward from the intermediate position (position R in FIG. 2) to the third position. As shown in the figure, it is located at the groove end of the guide groove 68 (the position of the lock operation engagement pin 98 at this time is referred to as the rear end position). That is, the operating characteristics of the lock operation engagement pin 98 are set so that it selectively moves between these three positions.

Next, to explain the operation of this locking mechanism 60, first, when the top 30 is in the open position, the locking engagement pin 98 is set at an intermediate position as shown in FIG. The engagement pin 98 causes the louver 66 to move in the direction of arrow a.
direction and positioned at the engagement position. Also, in this case, the second convex portion 73 of the second lever 66 or the second lever? By engaging with the first convex portion 75 of 67, the first convex portion 75 of
Rotation of the lever 66 in the direction of the arrow, that is, in the direction of disengaging the first convex portion 72 and the striker 62, is restricted.

Therefore, in this state, even if the lock operation engagement pin 98 moves from its intermediate position to the front end position as the top 30 closes, the engagement state between the first convex portion 72 and the striker 62 is maintained. .

On the other hand, the state shown in FIG.
When moving from the state shown in the figure) to the moving position shown in FIG. 10, the lock operation engagement pin 98 is roughly retreated from its intermediate position to the rear end position. Then, the third
As shown in the figure, the lock operation engagement pin 98 comes into contact with the second protrusion 76 of the second lever 67, rotates it in the direction of arrow d, and positions it at the disengagement position. As a result, the engagement between the first convex portion 75 of the second lever 67 and the second convex portion 73 of the second lever 66 is released, and the second lever 66 moves from its engaged position to its disengaged position. Therefore, the engagement between the first rule 51 and the second rail 52 is released, and the board member 20 can be swung (in the direction of arrow m) by the swiveling mechanism S.

On the other hand, in the case where the board member 20 is moved from its movement position to its storage position, when the board part 10 and 20 are located at its storage position, each of the above-mentioned members is in the positional relationship shown in FIG. 3. . When the lock operation engagement pin 98 moves to the intermediate position from this state and sets the top 30 to its open position, the lock operation engagement pin 98 again comes into contact with the third protrusion 74 of the louver 66 and The lever 66 is again positioned in the engaged position (as shown in FIG. 2). Therefore,
At the time when the board member 20 is returned from the moving position to the storage position, even if the first rule 51 of the guide rail 50
Even if the alignment between the first rule 51 and the second rail 52 is not done properly, the relative position between the second rule 51 and the second rail 52 in the vertical direction and the rail axial direction can be changed by operating the second locking mechanism 60. is securely set in place and
The alignment between the first rule 51 and the second rail 52 is performed with high precision.

In this embodiment, the lock bracket 63
A contact piece 71 is provided at the front end of the board member 20, and when the board member 20 swings from its moving position to its storage position, the corresponding contact piece 71 is brought into contact with the inner surface of the striker bracket 61, thereby positioning the rail in the width direction. I have them do this in advance.

The fitting mechanism 80 includes a conical fitting recess 82 (corresponding to a locking portion in claim 4) formed in the rear end surface 51b of the first rule 51 and a front end surface of the second rail 52. 52b (corresponding to the engaging portion in claim 4). This fitting mechanism 80 is connected to the board member 2.
0 moves from the movement position to the storage position, the protrusion 81 fits into the fitting recess 82, thereby changing the triaxial direction at the joint between the first rule 51 and the second rule 52. Perform positioning. That is, this fitting mechanism 80, together with the locking mechanism 60, connects the first rule 51 and the second rail 52.
However, in the case of this fitting mechanism 80, both the protrusion 81 and the fitting recess 82 are directly attached to the rails 51 and 52, so it is more effective than the locking mechanism 60. Highly accurate alignment can be performed.

In this way, the position regulating bag HP consisting of the locking mechanism 60 and the fitting mechanism 80 allows the guide rail 50 to be controlled by the fifth rule.
By aligning the first and second rails 52,
Integration of the guide rails is promoted and smooth movement of the top 30 is ensured.

Note that the locking mechanism 60 is connected to the board member 2 as described above.
0 is connected and fixed to the vehicle body side member (i.e., the second rule 51), but in addition to this, for example, when the board member is positioned at its moving position, the second lever 6 of the locking mechanism 60
The lock mechanism 60 can also be used as a campus fixing mechanism by configuring the first convex portion 72 of the trunk lid 8 to engage with an engagement bin (not shown) on the campus support stand 13 side provided on the trunk lid 8. It is.

As shown in the figure, it is placed on the board member 20 in a folded state and can be selectively set to an open position in which the opening 48 is opened.

In addition, in the closed state of the hood 30, each panel 31 to 33
Both side edges of the base frame 40 are sealed by coming into contact with a sealing material 16 provided at the peripheral edge of the opening 48 of the base frame 40, as shown in FIGS. 12 to 16. Further, a wire 17 is provided at the side end of each panel 31 to 33 so as to connect these panels in the front-rear direction, and this wire 17 is also connected to the side edge of each campus 34 and 35. (not shown), and both side edges of each campus 34 and 35 are connected to each panel 31 to 31 which are transmitted via this wire 17.

It is linked and engaged with a bracket 88 attached to a. In addition, in the state where the first link 92 is engaged with the first engagement pin 95 in its second guide groove 100,
The lower end 92a is pivotally supported to the front end of the bracket 88 via a connecting pin 108 (see FIG. 5), while the other end 92b is connected to the third link 94 via a third engagement pin 97. The first guide il together with one end 94a of
It is connected to i￥99. Further, the second link 93 has one end 93a swingably supported on the intermediate portion of the bracket 88 via a connecting pin 109 (see FIG. 5), and the other end 931) 5), the third link 94 is relatively rotatably connected to the other end 94b of the third link 94. Note that a guide roller 102 is attached to this connecting bin 110. Further, the second engagement pin 96 is engaged with the third link 94 . Therefore, these three links 92 to 94 and the shoe bracket 88 constitute a four-bar link.

The front moving device Q is in a state where the slide body 91 is positioned at the leading edge of the guide rail 5° (i.e., the tip 51b of the first rule 51) by the cable 181 (i.e., at the tip of the hood 3o). In the closed position), as shown in FIG. 5, the guide roller 102 is engaged in the first notch 53 formed in the first rule 51, thereby restricting its forward and backward movement. ing. In this state, the third engaging pin 97 is located on the rear end side of the first guide groove 99, the first engaging pin 95 is located on the front end side of the second guide groove 100, and The second engagement pin 96 is located on the front end side of the third guide il l Ol. Further, of the second guide groove 100 and the third guide groove 101, the formation direction of the second guide groove +00 is set so as to extend in the vertical direction in the first state,
Further, the formation position and direction of the third guide groove 101 are set such that the first half extends substantially horizontally and the second half extends obliquely downward.

(Rear side moving device) The rear side moving device R has almost the same configuration as the above-mentioned front side moving device Q, and as shown in FIGS. It has a slide body 111 which is attached so as to be movable.

This slide body 111 has a first guide groove 118 formed on its outer surface 111a, and a second guide groove 1
19 with a first link 112 and a second link 113'F
It is swingably connected to a bracket 89 attached to the second panel 32 via a third link 114 having a third guide groove +20. And the first link 112
The first engagement pin provided on the slide body III side in the second guide groove 119 of! 15, and the second engagement pin 116 provided on the slide body Ill side is engaged in the third guide groove 120 of the third link 114, as in the case of the front moving device Q described above. The unique structure of this rear moving device R is that the inclined portion of the third link 114 is shorter than that of the third guide groove lot of the front moving device 1Q;
When the locking pin +21 connecting the third link 114 and the second link +13 is in the closed position of
It is inserted into the notch 55 and the slide body 11
1, an arm 123 having a locking pin 125 and a slide pin 126 is attached to the tip end Iflb of the arm 123 via a fulcrum pin 124. Note that the locking pin 1 of this arm 123
25 and the slide pin 126, the locking pin 125 is in the first loop when the top 30 is in the closed position, as shown in FIG.
The second notch 54 formed in the lower flange 51c of the flange 51
In other than the closed position, it engages in the concave groove 51f of the second rule 51 as shown in FIG. Further, the slide pin 126 always moves on the upper surface 51c of the above-mentioned rule 51.
It is arranged so as to straddle the first rail 51 in the width direction thereof. When the locking pin 125 is in the groove 51r of the first rule 51, it can fit into the locking portion 103 of the front moving device Q. Note that this rear moving device R has its locking pin 12+ in the third notch 55 of the third rule 51 and its locking pin +25 in the second notch 54 when the top 30 is in the closed position. By engaging each of them, their forward and backward movement is restricted. Further, unlike the front moving device Q, this rear moving device R does not have a driving means in that case.

(Operation) Front side moving device Q and rear side moving device R configured in this way
The top 30 connected to the guide rail 50 via the hood 30 is driven to open and close as follows. In other words, first! 30 is in the closed position (see FIGS. 8 and 11), the front moving device Q moves the front end 51 of the rule 51 as shown in FIG.
c, the first panel 31 is arranged substantially parallel to and close to the first rule 51, and its outer peripheral portion is sealed with the base frame 40.

The rear moving device R is located near the rear end 51a of the second rule 51 as shown in FIGS.
The panel 32 has the same rule 51 as the first panel 31 described above.
They are arranged substantially parallel to and close to each other. In the closed position of the top 30, both the front moving device Q and the rear moving device R engage with the guide rail 50 in the vertical direction, so even if a suction action is applied to the top 30 during driving, The flapping is effectively suppressed, and the durability of the hood 30 is improved accordingly.

From this state, the opening operation of the hood 30, that is, the motor unit 1
When the cable tet is pulled by 60, the slide body 91 moves to the bracket 88 in the front moving device 1Q.
The third engagement pin 97 moves in the first guide groove 99 from the front end toward the rear end. In the first half of the movement, the first engagement pin 95 moves toward the rear end within the second guide groove 100, causing the first link 92 to rotate in the upright direction, and in the second half, the first link 92 rotates in the rising direction. The second engagement pin 96 is connected to the third guide groove 101.
By moving the inclined part of the
The link 94 rotates upward about the third engagement pin 97, and the guide roller 102 engages the first notch 53 of the first rule 51.
and is moved onto its upper surface 51c. This is the state shown in FIG. In this state, the first
The entire panel 31 is floating and is no longer in contact with the peripheral edge of the base frame 4o. In addition, in this embodiment, the height difference of the third guide groove 101 of the third link 94 is set larger than the height difference before and after rotation of the second guide groove 100 of the first link 92, so that the bracket 88 is tilted forward. I'm trying to tilt it to the state.

When the cable 161 is further pulled, the front moving device Q moves toward the rear of the vehicle while keeping the posture shown in FIG. 6 while folding the first campus 34. And the rear moving device R
When the front position of the rear moving device R is reached, the slide pin 126 provided on the arm 123 of the rear moving device
As the front moving device Q moves, the arm 123 is guided by its first locking surface 104 and rotated upward. As a result, the locking pin 125 separates from the second notch 54 of the second rule 51 and its groove 5
1d, thereby integrally connecting the front side moving device Q and the rear side moving device R.

When the front moving device Q further moves rearward from this state, the slide body 111 in the rear moving device R moves rearward with respect to the bracket 89, and the front moving device Q
The second panel 32 is attached to the base frame 4 in the same manner as in the case of
0 (this state is the state shown in FIG. 7). At this time, in this front moving device, the height difference before and after the rotation of the first engagement pin 115 of the first link 112 and the third guide groove 1 of the third link 114 are
The second panel 32 is made to be approximately parallel to the second rule 51 by appropriately setting the relative relationship with that of the second panel 20. Therefore, the front moving device Q and the rear moving device R
Since the first panel 31 and the second panel 32 have different inclination angles, the first panel 31
and the second panel 32 are stored in an overlapping state in the vertical direction, and a gap sufficient to accommodate the first campus 34 is secured between them.

Further, when the cable 161 is pulled, the front moving device Q and the rear moving device R integrally move rearward while folding the second canvas 35, and move from the second rule 51 to the second
It is moved to the rail 52 side and stored and placed on the board member 20 (open position of the hood 3o). This state is the state shown in FIG.

In this state, the first panel 31, the second panel 32, and the third panel 33 are folded in an overlapping state in order, the first canvas 34 is between the first panel 3I and the second panel 32, and the second canvas 35 is between the first panel 3I and the second panel 32. 2nd panel 32 and 3rd panel 3
They are stored between 3. Therefore, this hood 30
In the folded state, the width in the longitudinal direction and the height and clearance in the vertical direction are both small, and the aerodynamic characteristics and appearance of the vehicle body are improved accordingly. Also,
In particular, since the hood 30 is small when folded, the hood 30 does not obstruct the driver's rear view when it is placed on the trunk lid 8 as shown in FIG. 10. In addition, as shown in FIGS. 8 to 1O, there are folding sections at the rear ends of the first panel 31 and the second panel 32 to prevent the first canvas 34 and the second canvas 35 from bending at a sharp angle. A guide member 36 is provided.

On the other hand, when closing the top 30 from the open position to the closed position, the front moving device Q and the rear moving device R move until the rear moving device R reaches a predetermined position in the closed position of the top 30. That is, until the locking pin 125 of the rear moving device R reaches the position of the second notch 54 of the second rule 51, it moves forward in the connected state. And the locking pin +2
5 reaches the second notch 54 of the second rule 51 and engages in the second notch 54, the arm 123 rotates downward and the slide pin 126 engages the locking portion of the front moving device Q. 103, and the connection between the front side moving device Q and the rear side moving device R is released. Therefore, from then on, only the front moving device Q moves forward to the initial position with the rear moving device R remaining, and the top 30 is positioned at the closed position. That is, when the top 30 is closed, it is extended sequentially from the rear side of the vehicle body.

Furthermore, as in this embodiment, the floating mechanism in the front moving device Q and the rear moving device R is composed of a cam mechanism consisting of a four-bar link mechanism, a guide groove provided in each link, and an engagement pin that engages with the guide groove. When configured by a combination, the floating time is shortened by the floating action of the cam mechanism compared to, for example, when configured with a simple swing link, and as a result, the opening/closing time of the top 30 is shortened. It will be possible to achieve this goal.

In addition, in the case of this embodiment, since the floating mechanism of the top 30 is configured by a combination of a link mechanism and a cam mechanism, the floating dimension that is borne by the cam mechanism out of the total required floating dimension (i.e., the difference in height of the guide groove) can be reduced by the portion covered by the link mechanism, and since the links are in a collapsed state when the top 30 is in the closed position, the front moving device Q and the rear moving device under the closed position of the top 30 can be reduced by the portion covered by the link mechanism. The vertical dimension of R can be kept smaller than in the case where the floating mechanism is composed of only a simple cam mechanism. This means that when the vehicle height is kept constant, a large head clearance above the occupant can be obtained, which is suitable for expanding the space for a single unit.

Further, the levitation operations of the front moving device Q and the rear moving device R are all performed by the pushing and pulling force of the cable +61 as described above. In this case, for example, if the flotation mechanism was configured with a simple link mechanism, a very large operating force would be required to raise the link in the collapsed state, but as in this example, this can be combined with a link mechanism and a cam mechanism. In the case of a combination of the following, the operating force can be easily reduced by setting the shape of the guide groove so that the operating force can be used effectively, which is effective in terms of downsizing the device.
