DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a canvas top structure for a vehicle in which an opening formed in a vehicle body roof is covered with a flexible canvas so that it can be opened and closed. This invention relates to a canvas top structure for a vehicle that can be attached to and detached from the roof.

(Prior art and its problems) In recent years, various oven top structures have been proposed for vehicles such as passenger cars, which allow the roof of the vehicle body to be opened and closed.
One of them is a canvas top structure disclosed in Japanese Patent Application Laid-Open No. 63-61629.

As shown in FIGS. 3 to 5, in this canvas top structure, a canvas frame 6 is mounted around the periphery of a rectangular opening 4 formed in the vehicle body roof 2, and the canvas frame 6 is mounted in the vehicle width direction. Guide rails 8 are provided on both sides of the vehicle along the longitudinal direction of the vehicle body, and a canvas mechanism C consisting of a canvas top frame 10 and a canvas 12 is attached to the guide rails 8. .

The canvas top frame 10 is slidable in the front and back direction along the guide rail 8, and the canvas 12 is a flexible canopy that is attached to the canvas top frame 10 and extends through the opening. 4 blockages are now possible.

The canvas frame 6 has a main frame 14 integrally attached to the vehicle body roof 2, and bolts and nuts 16 are installed inside the vehicle rear end of the main frame 14 and the second main frame 14.
It consists of a plate-shaped sub-frame 18 that is detachably attached by means of, for example, a plate-shaped sub-frame 18.

The guide rail 8 is divided into a guide rail 8a on the main frame 14 side and a guide rail 8b on the subframe 18 side, and these are lined up in a line when the subframe 18 is attached to the main frame 14. They are each integrally fixed to the main frame 14 and the subframe 18 as shown in FIG.

The canvas top frame 10 includes a plate-shaped front end movable canopy 20 to which the front edge of the canvas 12 is fixed and which engages with the guide rail 8b and slides back and forth while being guided by the guide rail 8b. A plate-shaped rear end side fixed canopy bone 2 whose rear end edge is fixed and which is fixed to the subframe 1.8.
2, and the front end movable canopy bone 20 and the rear end side fixed canopy bone 22
The canvas 12 is arranged at a predetermined interval between
It is mainly composed of a plurality of movable canopy ribs 24 to which the intermediate portion of the canopy is fixed.

The front end movable canopy bones 20 and the intermediate movable canopy bones 24 are combined into a plurality of pairs by sequentially adjacent front and rear movable canopy bones and connected by link rods 26.

The front movable canopy rib 24 of each set is attached as a sliding movable canopy rib 24a by being engaged with a guide rail 8 disposed in the opening 4 via a slide shoe 28 so as to be movable. , the rear canopy bone 24 of each group is moved downward by the link rod 26 as a vertical movable side movable canopy bone 24b with respect to the front end side movable canopy bone 20 and the sliding side movable canopy bone 24a on the front side. It is possible to move.

When the canvas 12 is opened, the vertically movable side movable canopy bones 24b of each phase move upwardly relative to the front end side movable canopy bones 20 and the sliding side movable canopy bones 24a, and the canvas 12
2 is folded into multiple stages and the rear subframe 18
When the canvas 12 is closed, the vertical movable side movable canopy ribs 24b of each set are located at approximately the same position in the vertical direction as the sliding side movable canopy ribs 24a. , the opening 4 is closed with the canvas 12 supported by these canopy ribs 20, 22, 24.

In addition, the canvas top frame 10 is attached to the subframe 18.
An opening/closing drive mechanism 30 is provided which moves the canvas top frame 10 back and forth to fold and extend the canvas top frame 10 and the canvas 12 fixed thereto.

The opening/closing drive mechanism 30 includes a drive unit 34 that advances and retreats the wire rod 32 in the longitudinal f direction, and a drive motor 36. The drive unit 34 is fixedly provided at the center of the vehicle width direction on the upper surface side of the subframe 18. .

Further, the drive motor 36 is located below the drive unit 34 and fixed to the lower surface side of the subframe 18.

The wire rod 32 has one drive side tip attached to the slide shoe 28 of the front movable canopy 20 with a metal fitting (not shown).
When the canvas 12 is closed, it is moved forward along the guide rail 8 and inserted into an insertion groove (not shown) formed therein.

Further, the other end of the wire rod 32 on the idle side is inserted into a storage vibe 40 fixedly disposed on the upper surface of the subframe 18, and is moved back and pulled out from the guide rail 8 when the canvas 12 is opened. The wire rod 32 that has been removed is housed in the storage pipe 40.

Furthermore, the electrical wiring 42 of the drive motor 36 is connected to the coupler 4.
It is detachable via 4.

Therefore, according to this canvas top structure, the canvas 12 is fully opened i-,? , : In state, canvas 12. canvas) Tsubu'A=Mi1. O, subframe side guide rule 81) and opening/closing drive mechanism 30
It is possible to integrate it into the sub-71 norm 18 and remove it from the main frame 14, which not only allows the car body roof 2 to open even wider, but also allows the canvas top bone to be attached and removed! 10 can also be prevented from falling apart.

By the way, the subframe 18, which serves as a detachable member, is fixed to the main frame 6 via bolts and nuts 16, but since the ease of attaching and detaching the subframe 18 is extremely poor, the latch handle, etc. The applicant has proposed a device in which the subframe 18 can be attached and detached with one touch using a locking member.

However, when attaching and detaching the subframe 18 using the locking member in this manner, although the operability is greatly simplified, there is a risk that the lock may be easily released regardless of the open/closed state of the canvas mechanism C. .

That is, when the opening/link member is unlocked while the canvas mechanism C is extended so as to close the opening of the vehicle roof, the canvas top frame 10 comes off the guide rail 8 and the canvas mechanism C is opened. There was a problem in that it would fall apart, making subsequent assembly extremely difficult.

SUMMARY OF THE INVENTION In view of these conventional problems, it is an object of the present invention to provide a canvas top structure for a vehicle in which the locking member cannot be unlocked when the canvas mechanism is not in the folded state.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes an opening formed in a vehicle body roof, a detachable member that is detachably attached to cover one side of the opening in the longitudinal direction of the vehicle; A canvas top structure for a vehicle, comprising a canvas mechanism in which one end is fixed to the detachable member and the other end is capable of opening and closing the opening of the vehicle body roof by moving the opening in the longitudinal direction of the vehicle. A locking member for fixing the detachable member to the vehicle roof side is provided, and a lock management mechanism is provided for preventing release of the locking member in a state other than the folded state of the canvas mechanism.

(Function) With the canvas top structure of the vehicle of the present invention having the above configuration, by providing the locking member, the work of attaching and detaching the detachable member to the vehicle roof side is greatly simplified. Since the locking member is prevented from being released by the lock management mechanism when the canvas mechanism is not in the folded state, it is possible to prevent the canvas mechanism from being erroneously unlocked when it is in the extended state.

(Example) Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

That is, FIGS. 1 and 2 show a canvas top structure for a vehicle showing an embodiment of the present invention, and as described in the section of the description of the conventional technology, this canvas top structure has an opening formed in the vehicle body roof. The opening of this opening is attached to the canvas mechanism.

Since the canvas top structure is closed and a similar structure is adopted in this embodiment, a detailed explanation of the overall structure of the canvas top structure will be omitted.

Furthermore, as shown in FIG. 4, the canvas mechanism is also driven to open and close through a wire rod driven by a drive unit.

FIG. 1 is a perspective view showing the main parts of a canvas top structure showing one embodiment of the present invention, and a part thereof is further shown in the perspective view of FIG.

In FIG. 1, 100 is a latch handle as a locking member, and this latch handle 100 fixes a subframe 102 as a detachable member to a main frame 104 configured as the roof side of the vehicle body.

The latch handle 100 is attached to a support shaft 10 on a bracket 06 mounted on the lower surface of the vehicle rear end of the subframe 102.
A handle body 110 is attached to the handle body 110 so as to be vertically movable via the handle body 110, and a U is pivotally attached to the handle body 110 so as to be rotatable on the front side of the vehicle (the front side in the figure) from the spindle 108 of the handle body 110.
It is composed of a letter-shaped hanging piece 112 and a hook 114 attached to the main frame 104.

The latch handle 100 is in a locked state in the illustrated state, and in order to release this, the handle main body 110 is
This is done by rotating the subframe 102 downward around the center 08, and in this state, removing the hook 112 from the hook 114, and in this unlocked state, the subframe 102 can be removed.

On the other hand, to lock the latch handle 110, perform the opposite operation to the unlocking operation, and move the latch piece 112 to the hook 11.
This is done by pushing up the nozzle main body 1]0 after it is hooked onto the handle 4.

The latch handle 100 is provided with a lock management mechanism 120 for regulating locking and release thereof.

That is, the lock management mechanism 120
The regulation bin 12 provided perpendicularly to the side surface 110a of 10
4, and this regulation bin 124 is slidably attached to the subframe 102 via a bracket 122.

The tip of the regulation bottle 124 is
When the regulation pin 124 is engaged with the locking hole 110b, the release operation of the latch handle 100 is prevented and the locking By removing and removing the regulation bottle 124 from the hole 110b, the latch handle 1.00 is set to a releaseable state.

A first flange] 26 and a second flange 128 are integrally fixed to the regulation bottle 124, and one side of the first flange 126 (opposite side of the latch handle 100) has a recessed tapered surface. 126a is formed, and the first claw piece 130 is arranged to be able to lock onto this tapered surface 126a.

On the other hand, a bifurcated distal end portion of a second claw piece 134, which is driven forward and backward through a solenoid 132, is locked to the second flange portion 128 so as to straddle both sides thereof.

The end of the regulation bin 124 opposite to the latch handle 100 is connected to the subframe 1 via a bracket 136.
Supported by 02.

The first claw piece 134 is fixed to a downwardly protruding portion of a support shaft 138 that passes through the top and bottom of the subframe 102 and is rotatably supported, and a lever] 40 is attached to the upwardly projecting portion of this support shaft 138. will be permanently installed.

A bent portion 140a is formed at the free end of the lever 1.40, and as shown in FIG. 2, this bent portion 140a is connected to a wire rod for driving a canvas mechanism (not shown). ] 42 so as to be able to come into contact with it.

That is, the wire rod 142 is attached to the subframe 102.
The wire rod 142 is housed in an outer tube 144 fixed to the outer tube 144, and moves within the outer tube 144 when the canvas is opened or closed via a drive unit (not shown).

Therefore, when the end of the outer tube 144 is disposed opposite to the bent portion 140a and the opening of the vehicle roof is fully opened, the length of the wire rod 142 is a predetermined length from the end of the outer tube 144. By setting the canvas mechanism so that it protrudes by a certain amount, when the canvas mechanism is completely folded, the bent portion 140a is pressed by the wire rod 42 that protrudes from the end of the outer tube 144.

Then, the lever 140 and the first claw piece 130 are rotated, and the engagement between the first claw piece 130 and the first collar portion 126 is released.

Note that the lever 140 is moved in the direction of the outer tube 144 via a spring 146 (see FIG. 2), that is, in the first direction.
The claw piece 1'30 is pressed in the direction in which it is locked to the first flange portion 126.

On the other hand, the solenoid 132 that moves the second claw piece 134 back and forth is driven by excitation and demagnetization signals output from the controller 138.

That is, a return spring (not shown) is housed inside the solenoid 132, which urges the second claw piece 134 in the direction of retreating, and when the solenoid 32 is energized, the second claw piece 134 acts as a return spring. The second claw piece 134 is pushed back against the second claw piece 134 and is demagnetized.

A switching signal from an ignition switch 150 provided as means for detecting a stopped state of the vehicle is input to the controller 38, and only when an ignition OFF signal is input, the controller 150 switches the solenoid 13.
2, a demagnetizing signal is output.

With the above-described configuration, in the canvas top structure of this embodiment, when the canvas mechanism is not folded, the wire rod 1
42 is not projected, the link 140 is rotated in the direction of the outer tube 144 by the spring 145, and therefore, in this state, the first claw piece 130 is locked to the first flange 126.

In this locked state of the first claw piece 130, the regulation bottle 124 is prevented from being removed from the locking hole 110b of the latch handle 100.

On the other hand, when the ignition switch 150 is in a position other than OFF, that is, when it is in the ACC, ON, and 5TART positions, an excitation signal is output from the controller 148 to the solenoid 132, so the second claw portion 132 is in the protruded state. The regulation bottle 124 is engaged with the locking hole 110b via the second flange 128 that is engaged with the second flange 128.

Therefore, when the opening of the vehicle body roof is closed by the canvas and when the ignition switch 150 is not OFF, the regulation bin 124 is closed to the locking hole 110.
b, it becomes impossible to rotate the handle body 110 of the latch handle 100, and the latch handle 100 is not unlocked.

Therefore, even if an attempt is made to accidentally operate the latch handle 100 while the canvas mechanism is extended, the latch handle 100 will not be unlocked, thereby preventing the subframe 102 from detaching and reliably preventing the canvas top frame from falling apart. .

Furthermore, it is possible to reliably prevent the subframe 102 from being disengaged even while the vehicle is running.

On the other hand, when the opening of the vehicle body roof is fully opened and the canvas mechanism is folded, the wire rod 142 protrudes from the end of the outer tube 144 and the lever 140
is pressed, the [first] claw piece] 30 is rotated, and the first - collar part 13 is rotated.
It is separated from 0.

Furthermore, in this state, the ignition switch 150 is turned to O.
When in the FF state, a demagnetizing signal is output from the controller 148 to the solenoid 132, so the second claw piece 13
4 is retracted while being engaged with the second flange 128, and along with this, the regulation bottle 124 is removed from the locking hole 110b of the latch handle EOO.

Therefore, when the canvas mechanism is in the folded state and the ignition switch 150 is OFF and the engine is stopped, that is, the vehicle is stopped, the latch handle 100 can be operated, and the handle body 110 can be pushed down. , the lock can be released by removing the hook 112 from the hook 114.

In this way, the subframe 102 can be removed by being unlocked, but since the canvas mechanism is folded, this prevents the frame of the canvas mechanism from falling apart when the subframe 102 is removed. This can be prevented, and since the vehicle is stationary, the subframe 102 can be safely attached and detached.

(Effects of the Invention) As explained above, in the canvas top structure of the vehicle of the present invention, the removable member is fixed to the roof side of the vehicle body via the locking member, and the locking member is not released on the canvas by the lock management mechanism. Since the mechanism is blocked when the mechanism is not in the folded state, the locking member greatly simplifies the work of attaching and detaching the detachable member to the vehicle roof side, and also prevents the detachable member from being removed when the canvas mechanism is extended. This has the excellent effect of reliably preventing the canvas top frame from falling apart, which is impossible.
