Abstract

PURPOSE:To aim at rotating a drive shaft in both directions upon failure by screwing a nut on a projecting end part of a movable roof drive shaft which is coupled to a motor through the intermediary of a slide clutch, so as to aim at releasing the clutch and at engaging the drive shaft with a spring upon counterclockwise rotation of the nut. CONSTITUTION:The rotation of a motor is transmitted through a slide clutch 3 to a drive shaft 4 so as to actuate a slidably and tiltably movable roof. A nut 5 formed therein with a engaging recess 11 and an engaging projection 9 is screwed on an projecting end part of the drive shaft coupled to the slide clutch 3 so as to be adapted to engage with a spring 8 and a pin 13 on the drive shaft 4. When a nut 5 is rotated manually counterclockwise, the spring and the recess 11 are engaged with the pin 13 and the projection 9, simultaneously with disengagement of the clutch. When the spring 8 is engaged with the recess 11, clockwise rotation is effected due to the shape of notches 12 formed in the recess 11. Upon failure the nut may be manually rotated in both directions, thereby it is possible to aim at operating the movable roof.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a sliding roof (particularly
This is an emergency activation device for a sliding/tilting roof (sliding/tilting roof) in which the slip clutch is held in the engaged state by a polygonal nut screwed onto the protruding end of the driven shaft, and for emergency activation, it is manually operated with a tool that grips the polygonal nut. It relates to a type that can rotate the driven shaft.

BACKGROUND OF THE INVENTION Electric drives of the above-mentioned type for sliding roofs, window panes, etc. of motor vehicles are known from West German Utility Model No. 77-20015. That is, in case of an emergency operation, for example if the drive motor fails, a tool (e.g. wrench, box spanner) can be inserted into the polygonal nut and then the driven shaft can be manually rotated by the tool to close the sliding roof. Can be done. During emergency operation, the slip clutch remains engaged, so that during manual emergency activation, a frictional moment in the slip clutch must be created upon rotation of the driven shaft. Thus, a relatively large force is required during emergency operation, and emergency operation is not easy.

A West German patent describes a drive device for displacing motor vehicle window panes and sliding roofs of the type in which an emergency actuation lever is provided as a separate structural part acting as a screw feed transmission mechanism for actuating the drive element by positive coupling via a coupling member. Third
, 529,753. Rotating the emergency actuation lever releases and disengages the friction clutch;
The driven element can be displaced via the emergency actuation lever without applying large forces. This is because the prime mover is separated from the driven element. A screw feed transmission mechanism induces axial movement for switching the clutch.

However, this switching operation acts in both rotational directions of the emergency actuation lever. In this case, special structural components are required, namely an emergency actuation lever and an additional form-locking clutch, and the equipment outlay is therefore relatively high. A particular problem arises when manually operating the slide/tilt roof in an emergency situation. This is because emergency operations in two rotational directions are required based on the vertical movement of the slide/tilt roof.

A device for moving automobile windows, sliding roofs, etc. that requires first removing a nut with a wrench in order to relieve the pressure that holds the coupling means in a force-coupling state during emergency operation is disclosed in West German Publication No. 2.743.982.

In this case, in order to rotate the driven element manually, a manual crank is inserted into the protruding free end of the driven shaft in a separate working step. This type of emergency operation is a hassle;
In this case too, problems arise when applied to sliding/tilting roofs.

The object of the present invention is to overcome the above-mentioned problems, to be structurally simple, to be able to carry out emergency operation with as little force as possible,
In particular, a slide that can be installed in the closed position from two directions.
To provide an emergency activation device suitable for emergency activation of a tilt roof.

(Means for Solving the Problems) As a means for achieving the above object, the present invention provides an emergency actuation device for a slide roof (particularly a slide/tilt roof) that can be driven by a drive motor through a slip clutch and a driven shaft. The slip clutch 3 can be adjusted by a polygonal nut screwed onto the protruding end of the driven shaft, and the driven shaft can be manually rotated using a tool gripping the polygonal nut for emergency activation. At the end of the driven shaft 4 facing away from the slip clutch 3, a spring device 7.7'', which cooperates with the polygonal nut 5 on the basis of force and/or positive connection in the disengaged state of the A certain configuration was adopted.

(Function) The operation mode of the emergency actuation device 1 will be explained in detail below with reference to FIGS. 1 and 2. The basic state of FIG. 1 shows the normal driving state of the sliding roof by the drive motor during emergency operation, and the spring device 7 and the first protruding portion 8 are sufficiently separated from the recess in the outer surface 10 of the polygonal nut 5 in the axial direction. Starting from, for example, a spanner is attached to the polygonal nut 5. By rotating the wrench counterclockwise, the polygonal nut 5 is sent along the thread of the driven shaft 4 in the direction of the spring device 7, and at this time the slip clutch 3 is disengaged and the spring of the slip clutch 3 is relaxed. As a result, the frictional moment disappears. At the end of this disengaging movement of the slip clutch 3, the first projecting part 8 slides on the outer surface 10 of the polygonal nut, and the rotational movement disengaging the clutch is clockwise, i.e. opposite to the structure of the recess 11. direction, so that the polygonal nut 5 is moved during counterclockwise rotation until the slip clutch is reliably disengaged. In this dissociated state, the second protruding portion 9 is attached to the bottle 1.
3, further rotational movement in the counterclockwise direction will cause the driven shaft 4 to be interlocked, thus allowing the sliding roof to be activated in an emergency manner. When the outer surface 10 of the polygonal nut 5 is rotated in the opposite direction to the initial rotational movement, that is, clockwise, in the disengaged position of the slip clutch 3 in which the outer surface 10 of the polygonal nut 5 is in close contact with the spring device 7, the polygonal nut 5 , spring device 7
The first protruding portion 8 of the polygonal nut 5 is securely held in the disengaged position by a form-fitting engagement with the recess 11 of the polygonal nut 5. That is,
In order to carry out an emergency operation of the sliding roof by means of the emergency actuation device 1, the driven shaft 4 can also be moved clockwise, ie in the opposite direction to the loosening direction of the polygonal nut 5. When the emergency actuation device 1 according to the present invention is used in a slide/tilt roof, emergency operation is performed as follows. If the roof is in the open position at the start of the emergency operation, attach the corresponding tool to the polygonal nut 5 and then rotate the polygonal nut counterclockwise to release the spring device 7 and the pin 13.
make sure it comes in contact with the In this case, the slip clutch 3 is disengaged. Now, during emergency operation, the polygonal nut 5 is further rotated counterclockwise with the slip clutch 3 in the disengaged state. In this case, the driven shaft 4 is coupled via the second projecting part 9 and the pin 13 so that the cover of the sliding roof can be placed in the closed position via a corresponding drive.

When performing an emergency operation using the emergency operating device 1 starting from the raised state of the slide/tilt roof cover, a corresponding spanner is attached to the polygonal nut 5 as described above.

Next, the polygonal nut 5 is rotated counterclockwise to engage the spring device 7 and the slip clutch 3 is disengaged. Then, by rotating the polygonal nut 5 counterclockwise, the driven shaft 4 is interlocked and the slide/tilt roof cover is raised to its final position, if it has not yet reached its final position. In this case, said cover rotates the polygonal nut 5 clockwise, i.e. in the opposite direction, and the driven shaft 4 is likewise interlocked, since in this case the polygonal nut 5 is engaged in the spring device 7. , the cover can be placed in the closed position by further rotation clockwise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which examples are shown.

With reference to FIG. 1.2, a first preferred embodiment (indicated generally at 1) of an emergency actuation device according to the invention will be described. The emergency actuation device 1 is used for a slide roof (especially a slide/tilt roof), which is not shown. In emergency operation, a sliding roof of this type is driven by a drive motor 2 (for example an electric motor) via a slip clutch 3 and a driven shaft 4, not shown in detail. Slip clutch 3
are typically spring loaded to provide frictional engagement of the connecting parts. In this case, the pressing force of a spring (not shown) of the slip clutch 3 can be adjusted by a polygonal nut 5 screwed onto the protruding end of the driven shaft 4. Advantageously, this polygonal nut is a hexagonal nut. This polygonal nut 5 serves as an adjusting nut for the slip clutch 3. As is clear from FIG. 1.2, the emergency actuation device 1 for emergency operation of a sliding roof has a spring device 7. This spring device 7 is expediently constructed in the form of a spring disc that can be slid along the projecting end 6 of the driven shaft 4. The spring device 7 has a first protruding portion 8 . Only one protruding portion is shown in FIG. 2, while the second portion is generally diametrically opposed. Furthermore, the spring device 7 has a second protrusion 9 which projects in the opposite direction to the first protrusion 8 and points in the direction of the free end of the driven shaft 4 . As shown in FIG. 2, there are also provided two second protruding portions 9 that are substantially diametrically opposed to each other. However, the second protruding portion 9 is different from the first protruding portion 8.
The arrangement is shifted by about 90° from the front. As shown, the first and second projecting portions 8.9 are curved as disc-shaped tongues from the annular base of the spring device 7. Spring device 7
On the outer surface 10 of the polygonal nut 5 facing
Starting from the outer surface 10 of the polygonal nut, a recess 11 (advantageously a notch) increasing in depth in the axial direction of the polygonal nut is provided. In this case, each depression 11 forms an inclined surface 12 .

In the embodiment of FIG. 1.2, the pin 13, which can be engaged with the second protruding part 9 of the spring device 7, is attached to the protruding end 6 of the driven shaft 4.
is inserted into. This pin 13 is connected to the slip clutch 3
The pin 13 is provided at a sufficient distance from the polygonal nut 5 in the axial direction so that the pin 13 engages with the second projecting portion 9 of the spring device 7 only when the spring device 7 assumes a disengaged state.

Referring to FIG. 3, another embodiment of the emergency actuation device (approximately 1
’) will be explained. In FIG. 3, the same or similar parts as in the embodiment of FIGS. 1.2 are given the same reference numerals. The polygonal nut 5 corresponds structurally to the polygonal nut of the previous embodiment and likewise has a recess 1 with an inclined surface 12.
1. The spring device 7', like the previous embodiment, has a recess 11 in the outer surface 10 of the polygonal nut 5, which corresponds to the previous embodiment.
It has a first protruding portion 8 that can cooperate with. On the other hand, the second projecting portion 9' is curved in a wedge-like manner in the direction of the driven shaft 4 and engages with a recess 14 configured as a circumferential groove in the free end of the driven shaft 4. Furthermore, as is clear from FIG. 3, the free end of the driven shaft 4 is designed to be flat. Since the emergency actuation device 1° operates in the same manner as the emergency actuation device 1 described above, a detailed explanation of its operation mode will not be given. In the embodiment of FIG. 3, instead of the second projection 9 and the pin 13 cooperating in the embodiment of FIG. A form-locking connection for the interlocking of the driven shaft is realized between them. The second projecting portion 9' of the spring device 7'' of FIG. 3 is forcefully connected to the recess 14 by the polygonal nut 5 when the latter assumes the position in which the slip clutch 3 is disengaged.

4 to 7, another embodiment will be described in which a protective cap 17 is further provided to cover the spring devices 7, 7°, the protruding end 6 of the driven shaft 4, and the polygonal nut 5. Risk of injury is thus avoided and contamination of the structural components of the emergency actuation device 1, 1' is prevented.

Emergency activation device 1 in the sense of the preceding embodiments for emergency operation of a sliding roof or a sliding/tilting roof;
In order to be able to insert a hexagonal wrench into the protective cap 17 in order to operate the protective cap 17, the external shape 18 of the protective cap 17 is preferably polygonal, preferably hexagonal. The flat portion 15 of the projecting end 6 of the driven shaft 4 is received with a fit in a corresponding opening of the protective cap 17, so that the protective cap 17 is connected to the driven shaft 4 in a rotation-proof manner.

The embodiment of FIG. 4.5 relates to a modification of the emergency activation device l'' of FIG. 3, while FIG. 6.7 relates to a corresponding modification of the emergency activation device 1 of FIG. 1.2.

All other details shown in FIGS. 4-7 are the same as in the previous embodiment and will not be described in detail.

4.6 shows the emergency operating device 1, 1' in a state in which the sliding roof is driven by the drive motor, while FIG. The emergency actuating device l, 1' is shown in a state in which the slip clutch 3 is disengaged and a force and/or positive connection is formed between the driven shaft 4, the polygonal nut 5 and the spring device 7,7' by means of the spring device 7, etc. .

The invention is, of course, not limited to the illustrated embodiment, but various design changes are possible within the framework of the invention. In particular, the direction of rotation of the polygonal nut 5 for disengaging the slip clutch 3 can also be selected to be opposite to the illustrated embodiment.

Furthermore, the first and second protruding portions 8.9. of the spring device 7.7''.
9" can be configured in other shapes. Depending on the use case, for example one first protrusion part or one second protrusion part 9"
,9゛ is sufficient. Of course, more than two of the above-mentioned projections 8, 9.9° can also be provided distributed over the circumferential surface of the spring device 7, 7°.

Furthermore, the emergency actuation device 1,1° can also be used for other devices (eg drive devices for window panes, etc.). According to the invention, it is possible in a particularly structurally simple manner to rotate the driven shaft 4 in both directions of rotation in the disengaged state of the slip clutch 3 during emergency operation of the emergency actuating device 1,1'', thus making it possible to rotate the driven shaft 4 in both directions of rotation. The protective cap 17 is preferably made of synthetic resin. Furthermore, during emergency operation, the polygonal nut 5 assumes an engaged state exhibiting motion resistance based on force coupling and/or form coupling in the disengaged state of the slip clutch 3, so that the emergency actuating device l, 1゛ overload is eliminated.

(Effects of the Invention) In the case of the emergency operating device according to the present invention, the slip clutch is always placed in the disengaged state first so that emergency operation can be easily carried out. Thus, when the polygonal nut is further rotated, the driven shaft can be easily rotated directly by the force and form coupling between the spring device, the polygonal nut, and the driven shaft, without using a slip clutch. The force and/or positive coupling of the members described above allows the driven shaft to rotate in either direction in the disengaged state of the slip clutch. In this case, the slip clutch is reliably held in the disengaged state, so that the emergency actuation device according to the present invention moves the driven shaft from the raised position, for example, in order to move the slide/tilt roof from the open position to the closed position. Suitable for sliding/tilting roofs that must be rotated in the opposite direction.

That is, during emergency operation, the tool is fitted into the polygonal nut, the nut is first rotated in the loosening direction using the screw at the front end of the driven shaft, the slip clutch is disengaged, and the driven shaft is manually rotated in both directions of rotation. It can rotate. Only in this position does the force and/or positive connection of the spring device, the polygonal nut and the driven shaft become effective.

The emergency actuation device according to the invention is provided with at least one recess on the face of the polygonal nut facing the spring device, which engages with at least one first protrusion of the spring device when the slip clutch is disengaged. Thus, the polygonal nut is held disengaged by a form-locking connection, regardless of the direction of rotation in which the driven shaft is to be actuated during emergency operation.

The spring device further has at least one second projecting portion which projects in the direction of the free end of the driven shaft and is capable of interlocking the driven shaft upon disengagement of the slip clutch. Thus, also in the disengaged state of the slip clutch, a form-locking connection of the spring device and the driven shaft is achieved, so that during non-straightening operation, the driven shaft can optionally be manually rotated in either direction. The driven shaft is interlocked, so
It has a pin projecting from the bottom surface and cooperating with the second protruding portion of the spring device. This pin can be inserted into the bore of the driven shaft.

Further, the second protruding portion of the spring device can engage with a recess (or, more specifically, a groove on the circumferential surface) of the driven shaft, so that the driven shaft can be reliably interlocked in the disengaged state of the slip clutch.

The spring device of the present invention has two first and second protruding portions, respectively. In this case, both first projecting portions are substantially diametrically opposed to each other, and both second projecting portions are also substantially diametrically opposed and approximately 90 degrees relative to the first projecting portion.
'It's staggered. In an embodiment of this kind, the spring device has a disc-shaped tongue which projects in the opposite direction from the bottom surface and cooperates with the polygonal nut on the one hand and the driven shaft on the other hand in the disengaged state of the clutch.

The recesses of the polygonal nut are preferably formed by notches, and it is expedient to provide a plurality of such notches distributed over the circumference of the polygonal nut.

In order to obtain sufficient axial spacing upon disengagement of the slip clutch, it is expedient to design the recess to be progressively deeper starting from the surface of the polygonal nut. That is, the recess forms an inclined surface, and in the disengaged state, the first protruding portion of the spring device positively engages the recess or notch.

It is particularly advantageous from a manufacturing technology point of view that the first and second projecting parts of the spring device are curved from the bottom side of the spring device, so that the spring device together with the first and second projecting parts can be produced as one structural member. It is characterized by

Preferably, the spring device is constructed as a spring disc which is attached to the driven shaft. In this way, the spring device only needs to be fitted at the final stage of assembly, which simplifies the assembly work.

According to the invention, the free end of the driven shaft, the spring device and the polygonal nut can be fitted with a protective cap that covers these parts and prevents them from spinning. Thus, the risk of injury is prevented and damage to the structural components underlying the protective cap is prevented.

Furthermore, in accordance with the invention, at least two diametrically opposed outer surfaces of the free end of the driven shaft can be configured to be flat and designed to receive the flattened driven shaft end within the protective cap.

It is expedient if the protective cap has a polygonal (preferably hexagonal) external shape. Thus, in case of an emergency operation, it is only necessary to fit the tool (e.g. a spanner) into the protective cap, and then carry out the emergency operation, first disengaging the slip clutch and then rotating the driven shaft to release the polygonal nut. , the movement of the sliding/lifting device can be carried out by force and positive coupling of the spring device and the driven shaft.

According to the invention, in particular for the closing of sliding and tilting roofs, an emergency actuation is provided so that the driven shaft can be rotated in both directions of rotation in the disengaged state of the sliding clutch by means of a force and positive connection of the polygonal nut and the spring arrangement. Can design equipment.
