Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a roof lid slidably guided along a lateral guide of a roof opening formed in the roof of a motor vehicle. The engaging drive means 1 causes the roof lid to be lifted outward by one point, and after being lifted by one point outward, the roof lid is moved by one point relative to the roof opening while simultaneously changing the tilted posture of the lid. Slidable, S and
The sliding roof mechanism for a motor vehicle is such that during its sliding, the rear part of the lid is located above the rear fixed roof surface of the motor vehicle.

One of this type of sliding roof (West German patent application no. 495
8.620) Accordingly, the lid I'i has a plurality of sliding or rolling elements on each side of the lid at or near its front edge; A curved lateral guide provided in the roof opening engages.

When the lid moves in the opening direction, the curved guide 1 lifts the rear edge of the lid above the outer surface of the roof and gradually brings it into a tilted position, and the angle of inclination is as follows: Every time you move backward one step, it becomes one step larger.

As a result of this increased angle of inclination, the distance between the leading edge of the nof opening and the leading edge of the lid increases, causing the lid 11 to protrude even further above the fixed roof surface of the motor vehicle.

therefore. The wind pressure resistance of the lid increases by one amount each time the lid is opened.

The air resistance coefficient of an automobile has a direct effect on fuel consumption, and the wind pressure resistance of the lid increases the coefficient.

Also, the known lids, when pushed far, cause vibrations while the vehicle is in motion and produce significant wind noise.

In the known sliding roof, the drive means acting on the lid have a threaded spindle, which spindle has a threaded spindle.
It is rotatable and stationary along the axial direction and is located at the center of the vehicle.

Further, the spindle 1 can be driven by the flexible shaft 1 in cooperation with a threaded nut fixed to the cover 1.

The lifted lid is only supported by the spindle 1 across the central plane in the longitudinal direction of the lid, and cannot be said to have sufficient stability.

In addition, the threaded spindle that is located in the center of the roof opening can easily become an eye-catcher and spoil the aesthetics.

This is the same in the case of a flexible shaft,
If the winding crank is installed near the dash board, the windshield will be
Although there are differences in degree, they will be divided into two.

This invention was made in view of the above points, and its purpose is to ensure that even if the lid is opened by one degree to the maximum possible extent, the air resistance coefficient of the automobile will not be substantially deteriorated by one degree, and the opened lid will remain solid. Another object of the present invention is to provide a sliding roof mechanism that can be held in a position with little vibration, generates low noise during operation, and does not expose the driving means for its operation to the extent that it interferes with the operation. .

In order to achieve the above object, the sliding roof 1 of the present invention has the following features: (a) The lid is rotatably and movably supported in the vicinity of its front edge in a known manner. There is.

(b) A lifting mechanism is provided in a known manner near the rear edge of the roof opening.

(C) The lid is slidably guided on the lifting mechanism.

(d) A lifting mechanism located on the side edge of the roof opening is coupled in a force transmittable manner to the drive means and the lid is opened by movement of the lid. 1 so that the inclination of the lid decreases while moving in the direction, and
During the movement of the lid in the closing direction, its height changes continuously so that the slope of the lid increases.

In the sliding roof mechanism 1 of the present invention, the device and arrangement of the lifting mechanism allows the lid to be positioned at each sliding position so that the lid is positioned between the lower surface of the lid and the rear fixed roof surface.
It protrudes above the fixed roof of the automobile by the amount necessary for one relative movement without contact.

Since the lifting mechanism is provided near the rear edge of the roof opening, the lid is reliably supported at each sliding position.

Since the lid has one sliding position at each sliding position and only protrudes one part above the roof surface, its effect on the air resistance coefficient of the automobile is negligible. The wind noise that occurs during the middle class is only mild.

The drive means located on both sides of the roof opening are
Almost no part of the outside is exposed.

The lid is slidably guided at its front edge and 1
At the same time, one shaft is rotatably supported at one end near the edge.

Therefore, while the lid is sliding, it is only supported by a hinge in the vicinity of its front edge, and the tilting posture of the lid is reliably controlled by the lifting mechanism 1.

One of the known air circulation devices for motor vehicles (West German Publication A I O 50 676), which has the feature (b) mentioned above, does not fit into one of the first mentioned categories. In the form of a roof structure, the lifting mechanism is formed as a plurality of pivoting levers.

Therefore, even if the lid moves backward by a maximum of one angle, only a relatively narrow front air flow gap is formed between the front edge of the roof opening and the front edge of the lid. .

In the specification, the meaning of the term "tilted position" 1
E. For one reference surface formed by the sliding plane I,
It refers to each position in which the lid forms a certain angle.

In a preferred embodiment of the invention, the lifting mechanism has a known screw telescope, which is mounted on both sides of the roof opening.

In this case, the inner end Ii of the screw telescope is fixed to a fixed part of the roof, and the outer end is a sliding joint slidably guided along a guide rail arranged on the lid. One is fixed.

In this embodiment, the screw telescope controls the tilting position of the lid as it moves.

The guide rail S mounted on the lid 1 and the sliding joint fixed to the outer end of the screw telescope cooperate with the support of the lid in each opening position f of the lid.
Reliably controls the tilting position of the lid.

According to another feature of the invention, two flexible threaded drive cables are provided as the drive means,
These cables remain engaged with the drive pinion while
They are guided in a conventional manner to transmit tension 5 and thrust, and each is guided on one side of the roof.

In addition, these cables are connected to the threaded portion of the cable (thus near the trailing edge of the roof opening) and to the fixed portion of the loop until the lid reaches its maximum tilted position prior to the start of the lid movement. Each of the pinions is in engagement with a driven pinion that is supported on the shaft, and one of the driven pinions is in mesh with a corresponding screw telescope.

According to this configuration 1, when the drive means is operated manually or by a motor, the lid is first pushed up above the roof surface from the closed position in which the lid is located flush with the roof surface, and at the same time The lid is rotated about its front edge until it reaches its maximum tilted position.

When the lid reaches this position, the operational engagement between the drive screw cable and the driven pinion is automatically released,
Therefore, even if the drive means are subsequently driven, the screw telescope 1 will not have any effect.

According to the first gist of the present invention, for the sliding operation of the lid,
A conveying device is provided, each having one threaded cable for driving one book.

This conveying device engages the connecting member to which the lid is connected when the lid reaches one maximum tilted position at one closed position.

Also provided are two flexible adjustable threaded cables guided in a manner capable of transmitting tension and thrust.

Each cable is placed parallel to one drive threaded cable on one side of the roof and also placed in its place.

Its front end firmly engages a member to which the lid is connected.

Further, each adjusting cable engages an adjacent driven pinion through its threaded portion 1 when the lid reaches the closed position 1 and reaches the maximum tilted position I.

According to the above configuration 1, when the drive means continues to operate after the lid has reached its maximum tilted position, an opening operation of the lid occurs, and the driven pinion ε does not move the lid.
The inclination of the lid is simultaneously reduced by the movement of the adjustment cable.

Here, while the lid is being raised, the screw telescope that had been screwed out once in the opposite direction is removed by pulling out the threaded cable for adjusting.
Driven.

That is, the screw telescope only needs to be screwed in once.

The engagement between the conveying device and the coupling member is maintained even during the movement of the lid in the closing direction, and the predefined position and position when the lid is moved in the closing direction. It will not be released until the maximum tilt position is reached.

When the drive means continues to operate from the state in which the lid is in the above-mentioned position, the lid, which has already been in the closed position, is swung back to its starting position, and is returned to its starting position. The lid is positioned flush with the roof opening.

The driven pinion is a gear 1 that meshes with a smaller gear.
Advantageously, it is mounted with a coaxial and rotatable key, and the small gear wheel is secured with a coaxial and rotatable key of the reacting screw telescope.

As a result, the gear connection between the driven pinion and the screw telescope can obtain an upward gear ratio.

Appropriately select the thread pinch of the screw telescope and/or the gear ratio between these two gears 1
In this way, the extension length of the screw telescope can be matched with the sliding length of the lid, so that the lid can be moved between the lower edge of the lid and the rear fixed roof surface at each sliding position. Just the distance necessary to keep them from coming into contact with each other.
I can lift one thing.

In order to ensure that the engagement between the conveying device 5 and the connecting member is released only when the lid is in the closed position, a spring is provided that releases the conveying device only once when the lid is in the closed position. It is advantageous if the tongue is provided with one coupling member 56°, where, when the lid is in the closing position, its spring tongue is provided with a shape facing one corresponding recess of the lateral lid guide. It's convenient to have one.

Therefore, the spring will not fit into the recess when releasing the conveying device from the connecting member, but
If the lid is in one more position, the spring tongs are engaged with the lid guide rail in such a way that the transport device cannot disengage the coupling member.

Embodiment I of the present invention will be described in detail below with reference to the drawings.

1 to 3. As can be seen from the side views shown in FIGS.
The lid 1 assumes different tilted postures at each moving position 1.

In FIG. 1, the lid 1 is in the moving position shown in FIG. It is still located in the closed position in the roof opening 2.

However, the rear edge of the lid is raised to the maximum extent, so that the lid assumes its maximum tilted position.
This will happen.

This maximum tilting position is the position in which the lid needs to be tilted just before it starts sliding.

The lid is moved to the rear l position shown in Figure 2.
The vehicle has slid about halfway in the opposite direction, and the front part of the roof opening is exposed.

In this state 1, the inclination of the lid is smaller than before, and the inclination is the same as when the lid continues to be moved.
The lower part of the lid gets closer to the rear fixed roof surface by 31 cm, making it even smaller by 1 cm.

In the maximum sliding open position 1 shown in FIG. 3, the slope of the lid is minimal and the lid only projects unnoticeably above the rear fixed roof surface 3.

The movement characteristic ii mentioned above is reversed when the lid slides and returns to the closed position.

A suitable structure for obtaining the appropriate and desired movement characteristics as described above will be described below with reference to the remaining drawings.
I will explain this.

In FIGS. 1 to 3, reference numeral 4 indicates a windshield. This windshield is shown only once to clearly show the direction of movement of the lid.

In the respective positions shown in FIGS. 4 to 7, the lid 1 is located in the roof opening 2 in its closed position.

The roof opening 2 is delimited by an enclosing frame flange 51 of the motor vehicle roof, indicated by the reference numeral 6.

The sliding roof frame 7 is firmly connected to the roof of the automobile and is adjacent to the flange 51. Normally, the side frame members of the sliding roof frame are connected to the front and rear flange 51. It is wider than the frame member.

Looking at FIG. 16, the outline of the cross section of the side frame members of the sliding roof roof can be seen.

The sliding roof is arranged symmetrically with respect to its central axis in the longitudinal direction, and in the following explanation, only one side of the roof will be described. Needless to say, a pair of each are provided.

The lid 1 is rotatably and movably supported near its front edge by a hinge assembly 1. One hinge portion 8 of the hinge assembly is fixed to the lid 1, and the other hinge portion 10 is fixed to the lid 1. , the hinge pin 91 is connected to the hinge portion 8 and the front guide shoe 111
This is fixed.

This situation is shown in detail in FIG. 9, for example.

A guide rail 12 oriented in the sliding direction is rigidly connected to the lateral wing parts of the sliding roof frame 7.

This guide rail 12 is shown in detail in FIG. 16.

A guide flange 13 of this rail extends inwardly opposite the roof opening 21;
At the top, a front guide shoe 11 is slidably guided along the longitudinal direction.

The upper part of the front frame member of the sliding roof part 7 is the mounting plate 1.
4 is firmly fixed, and this mounting plate I,
A tubular support 15 is attached for mounting the drive means.

The drive means have threaded cables 16 and 17;
These cables are guided in such a way that tension and thrust can be transmitted.

A drive pinion 18, which is rotatably journalled on the mounting plate 14, engages these cables 16 and 17.

The drive pinion 18 is connected via a drive shaft 19 to a manual crank device or an electric motor in a known manner.

Loop front area 1 and drive threaded cable 1
6 and 17 are guided through tubes 20 and 21, of which tube 21 is connected to a duct 221 in the guide rail 12 in the left-hand section 1 of the roof and in the right-hand section 1 of the roof. One side of the tube 20 is adjacent to one corresponding duct of the guide rail.

In the area SG1 on the left side of the roof, the tube 20 extends straight across and receives the free end of the drive threaded cable 16.

In the right-hand region of the roof, the tube 21 likewise extends straight through and receives the free end of the threaded drive cable 17.

, as the drive pinion 18 rotates in one or the opposite direction of rotation, the threaded drive cables 16 and 17 pass through the ducts of the tubes 20 and 218 and the guide rails adjoining them. Moving.

According to method 1 described below, the drive threaded cable is connected to a lifting mechanism disposed near the rear edge of the roof opening 2.

The stopping state of the drive threaded cable 17, particularly the drive threaded cable 17 located on the left side of the roof assembly, and the corresponding lifting mechanism member will be explained with reference to FIGS. 8 and 9. do.

As you can see from Figure 9, there is one drive threaded cable.
The guide tube 23 of No. 7 is in contact with the guide duct 221 at the rear end of the guide rail 12 .

The guide tube 23 is guided through a split housing 24 in which the cable 17 engages with a driven pinion 26 via a hole 25 in the guide tube 23.

This driven pinion 26 is rotatably supported by a shaft within the housing 24, and is also coaxially connected to a spur gear 271 provided within the housing 24, and is rotatably keyed. It's stopped.

The housing 24 is fixed to the sliding roof frame and is thus placed in a stationary state against the roof of the vehicle (FIG. 8).

The spur gear 27 is engaged with a small spur gear 28, which is rotatably and coaxially connected to the screw telescope 291.

This screw telescope constitutes a lifting mechanism for the lid 1 and includes an inner rod 30, an intermediate sleeve 31, and an outer sleeve 32.

The outer sleeve 321 and the spur gear 28 are joined.

The parts of the screw telescope are connected to each other by mutually engaging threaded parts l, as shown in FIG. 14.

Here, the rod 30 has a threaded portion on its outer circumference, the intermediate sleeve 31 has a threaded portion on its inner circumference and its outer circumference, and the outer sleeve 32 has a threaded portion on its inner circumference.

The rod 30 is non-rotatably mounted in a slip joint 33 so that when the outer sleeve 32, which engages the spur gears 27s and 28, rotates, the screw telescope retracts or extends its head in accordance with its direction of rotation. [to do] to do something.

Figure 7 ε and Figure 14 1 1, slip joint 3 as shown
3 has two lateral guides 34g and 35, which are fixed to each other by a connecting arm 361.

The pivot bearing pins 37 are fixed to a U-shaped pin support 381 in a state where they are coaxially arranged facing each other. and one in 35 has been penetrated.

The rod 30 of the screw telescope 29 is fixed to this pin support 38.

Due to the pivot axis 1 formed by the pivot bearing pin 371, the slip joint can be adapted to various tilted positions of the lid, and the screw telescope 1 is always 1, approximately vertical. 1 is retained.

The guide elements 34 and 351-i of the slide joint 33 act to guide the screw telescope 29 so as to be movable along the lid 1.

For this purpose, as can be clearly seen from FIGS. 7 and 14, one or two guide rails 40 and 41 are fixed to the reinforcing member 391 of the lid in a state facing each other. 34s and 351-1. It is slidably guided along these guide rails in the longitudinal direction.

In addition, in order to simplify the drawing in FIG. 4, the guide rail 40. U and 41 are not drawn.

For the same reason, the guide rail 12 is shown in Figure 7.
, O, and the same rail 1 The depiction of each connected part is omitted.

As shown in FIGS. 11 to 13, the first drive threaded cable 17 is provided with a 1′i helical threaded portion 42, and this threaded portion l thereby connects the 1st drive pinion 18 and The engagement with the driven pinion 26 is similar to that of a rack and pinion.

This threaded portion 42 is partial, in other words, it does not extend over the entire length of the drive threaded cable 17.

10S and 11. After the maximum lifting position of the lid 1 shown in FIGS. 10 and 11, the lid remains stationary without movement. It is in a state where it does not.

Therefore, even if the drive threaded cable 17 moves one inch in the longitudinal direction toward the right, the screw telescope 1 does not rotate any further, and the screw telescope is fully moved. It has a shape that is one inch longer.

As explained below, Figures 10 and 11
The movement of the lid 1 starts from this position of the lid.

As shown in FIGS. 4S and 6, a conveying device 43 is attached to a drive threaded cable 171 and extends through the slit 44 of the tube 21.

During the lifting operation of the screw telescope 29, the conveying device 43 moves freely in the slit 44 against the guide rail 121.

The position of the lid shown in FIGS. 10 and 11, i.e.
Maximum inclination position: At this point, the conveying device 43 is fixed to the guide shoe 11 at the connecting member 45 (largest inclination position).

If this drive continues, i.e. if the threaded cable 17 moves one step further to the right, the transport device A3 advances one step into the seating chamber 46 of the coupling member 45 and
This allows the spring tongue 47 , which borders the seating chamber 46 on its bottom surface, to fit into the recess 48 of the guide rail 12 .
It is elastically rotated one turn downward inwardly.

While this driving continues, the transport device 43
When the lid 1 hits the inner wall surface of the connecting member 45, the lid 1, which has been rotated and lifted, immediately starts sliding by one.

This sliding movement is limited by a stopper 491 near the rear edge of the roof opening (Fig. 13).
.

This stopper 49 is fixed to the sliding roof frame 71 and is located within the movement path of the guide shoe 11.

When the lid moves one direction in the closing direction, the drive threaded cable 17 is moved to the left.

At this stage, the conveying device 43 has the spring tongs 47
The protrusion 501 is in contact with it.

In addition, the spring tongs 47 move through the entire sliding movement l.
Since it is in contact with the guide rail 121 over the entire length, it cannot bend downward, and as a result, the conveying device 4
3 and the connecting member 45 is connected in the direction 1 in which the lid is closed.
Even while moving, it will definitely be maintained at 1.

10 and 11. When the lid position shown in FIGS. Can be bent.

Then, the conveyance device 43 moves over the protrusion 50 and rotates the spring tongue 47 downward t.

The front end of the spring tongue 47 comes into contact with the front part f of the recess 48 (FIG. 10), thus completing the sliding movement of the lid 1 in the closing direction.

The continuous change in the height of the lid 1 while the lid 1 is sliding is caused by the following movement of the screw telescope.

A second guide duct 51 is disposed inside the guide rail 12 to face the guide duct 22, and an adjustment threaded cable 52 can transmit tension S and thrust to the inside of the second guide duct. It is guided in such a way that it can be moved one distance in the longitudinal direction.

The driving threaded cable 52 has its front end fixed to the guide shoe 1iI by means of a conveying device 53 to which the cable 521 is fixed.

Therefore, when the lid is slid, the cable 52 moves together with the lid and slides inside the guide duct 51.

Further, the adjusting threaded cable 52 is connected to the guide tube 5
One movable piece is inserted in the 4.

Like the guide tube 23, the guide tube 54 extends through the housing 24, and is connected to the guide duct 511 of the guide rail 12 at its front end.

The guide tube 54 has a hole 55 in the housing 24 in the vicinity of the driven pinion 26 , through which the adjusting threaded cable 52 connects to the driven pinion 26 .
It can be engaged with.

As shown in FIG. 9, one free end of the adjusting screw cable 52 is not provided with a helical thread.

Therefore, under the conditions of each component shown in FIGS. 8 to 11, no engagement relationship for transmitting force is established between the adjusting screw cable 52 and the driven pinion 26.

However, when the lid starts to slide in the opening direction, the square-tooth threaded portion of the adjusting threaded cable 52 engages with the driven pinion 26, and the driven pinion 26 at this point It is only necessary to release the engagement with the helical threaded portion of the drive threaded cable 17.

The adjusting threaded cable 52 therefore drives the spur gear 27.2B by engaging the driven pinion 26 and thus drives the screw telescope 29.

In this way, the screw telescope is caused to extend and contract, and while the lid that has been rotated and lifted moves one step in the direction of opening, the screw telescope is retracted one step. .

As a result of this operation, the tilted position of the lid is such that the opening of the roof increases, and the tilt decreases.

While the lid is sliding in the closing direction, unlike the case described above, the screw telescope 29 is driven in the closing direction, and as the roof continues to close, the inclination of the lid increases. Do one thing.

Although the adjustable threaded cable 52 provides essentially one linear movement, it is also possible to use a rigid toothed rack instead.
A second guide duct in the guide rail is no longer necessary.

Also, in this case, the toothed rack is not guided along a curved path passing through the housing 24 as shown in FIG.

As shown, the housing 24 is of symmetrical construction so that it can be used on either the right or left side of the roof.
