Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a locking device for electrically centrally locking a door, in particular a motor vehicle door, comprising: at least one adjustment member which acts on the lock and is equipped with a motor; At least one control element with a switch, which can be operated by means of a key, and to which an adjustment element and possibly further adjustment elements are electrically connected.

Such a known locking device for electrically central locking by operating a lock in the driver's door or the passenger door has a so-called control member and a so-called adjustment member in each of the two doors. is accommodated.

A control element arranged in its own casing is actuated via a switching rod projecting from said casing by introducing and rotating a key into the lock of the door; via which it is connected to the adjustment element of the door concerned as well as to the adjustment element of another door.

The adjusting element is connected to a respective lock of the associated door via a respective switching rod projecting from the adjusting element.

This means that in the event of actuation of one of the control elements, not only the door to which this separate element is assigned is unlocked or locked, but also all other doors equipped with adjustment elements, as the case may be. The rear flap is also unlocked or locked.

In the case of the known locking devices for central candlesticks, it is necessary to arrange a control element and also an adjustment element in each door whose lock is to be locked with a key.

In this connection, it is important to note that adjusting elements with electric motors cannot be operated directly by means of a key, since they require the application of large forces, and can therefore only be operated via a control element, which controls the adjusting element by means of a motor connection. It is necessary to consider that it is only .

Therefore, significant expense is required for centrally lockable doors that can be locked with a key.

This is because in each door a separate control and adjustment element must be integrated, in which case said control and adjustment elements are connected to each other as well as to the other control and adjustment elements of the other door. It is necessary to connect the parts with cables.

The object of the invention is to provide a locking device of the type mentioned at the outset, which requires very little installation space and requires very little assembly and cable connection costs.

According to the invention, this problem is solved in that the control member and the adjustment member are
The switch can be controlled by the lock via at least one first mechanical coupling member and the motor can be coupled to the lock via at least one second mechanical coupling member. It was resolved by this.

According to the present invention, the following points can be obtained.

This means that the control element and the adjustment element are integrated into a single component, so that the number of components is considerably reduced.

Furthermore, it is not necessary to incorporate one separate control element and one adjustment element in each case in the driver's door and in the passenger door in connection with the lock, but rather a single component with the control element and the adjustment element. Just that is enough.

This not only simplifies assembly, but also significantly reduces installation space and eliminates the need for special cable connections between the control element and the adjustment element.

Furthermore, the desired ease of operation with the key is still maintained.

According to a particularly advantageous embodiment of the invention, the motor is connectable to the lock via a first mechanical coupling element and a second mechanical coupling element, and the motor is connectable to the lock via a first mechanical coupling element and a second mechanical coupling element; and the second mechanical coupling member, a first play is provided of a size such that the switch can be operated by a manually keyed lock without being electrically coupled to the motor. .

In this case, it is particularly advantageous that only the first connecting member is connected to the lock, thereby simplifying assembly.

Despite this, via said first coupling member corresponding to the switching rod, the force exerted by the lock for operating the switch can also be transmitted from the motor to the lock for unlocking and locking. It is also possible to transmit the force of
In this case, the key, which is rotated in the lock, does not impede easy movement when operating the switch.

This means that although the motor can be coupled to the same first mechanical coupling member as the switch to operate the locking mechanism of the lock, the connection between the lock and the switch is However, the connection between the motor and the lock is only made once the actuating distance provided for actuating the switch is exceeded.

The first play is therefore at least as large as the operating distance that the first coupling member travels in order to operate the switch.

In accordance with a further embodiment of the invention, the first play is limited by a force-releasable stop element, and furthermore the first coupling element together with the stop element is limited by a distance corresponding to the locking stroke. It is movable and furthermore, a play for overtravel of a second mechanical coupling element is connected to the gun side of the stop element in each case.

The locking device according to the invention can therefore be adjusted in a simple manner as follows.

That is, starting from each of the two possible end positions of the locking device, in which the associated lock is unlocked or locked, the first mechanical coupling member is first freed by the movement of the key in the lock. , then the motor is connected, and then the second coupling member is moved based on the connection of the motor to proceed through the remaining section of said play and act on the stop member, and this A force-transmitting connection between the first coupling member and the second coupling member then occurs, and this force-transmitting coupling is then maintained so that the first coupling member travels a distance corresponding to the locking stroke, and then:
Once the lock has assumed the new switching position, the second coupling member can be continued to be slid electrically without being damaged and the motor can be switched off.

Furthermore, in an advantageous embodiment of the invention, a movable push rod is provided as the first mechanical coupling element, one end of which is connectable to the lock and the other end of which is connected to the actuating member of the switch. A sliding member is provided as a second mechanical coupling member, which is movable relative to the pusher rod, for entraining the pusher rod by means of a one-force releasable stop element. and is configured to externally connect to a motor.

This arrangement can be carried out in a particularly space-saving manner.

This is because part of the sliding member can be accommodated concentrically within the push rod.

The arrangement is therefore compact and less susceptible to surrounding influences.

Furthermore, in an advantageous embodiment of the invention, the sliding element has a collar that can be slid in the bore of the pusher rod in order to entrain the pusher rod by means of a stop element that can be released under the influence of force; Furthermore, a releasable stop member for applying the collar is arranged in the hole of the push rod.

In an advantageous embodiment of the invention in this context, at least one bending spring is provided in the bore of the push rod as a stop element which can be released under the action of force.

The bending spring thus serves as a stop for the sliding member, unless a predetermined maximum force exerted on the spring is overcome.

Said maximum force is sufficient to operate the lock by the motor.

When the lock assumes the new locking position, the maximum applied force is overcome and the stop member frees the sliding member for a further travel distance corresponding to the overtravel.

Advantageously, three bending springs are distributed around the bore of the push rod.

As a result, the sliding member rests symmetrically on the bending spring, so that no tilting forces are exerted on the slidable sliding member, and the functionality of the locking position is ensured.

In a further advantageous embodiment of the invention, the sliding element has a cylindrical part and a rack connected to the cylindrical part, which rack is connected to the motor via a transmission element.

In the embodiment described, which is also simple, the sliding member is perfectly guided in the cylindrical part, whereas the rack, which is fixedly connected to the cylindrical part, converts the rotary movement produced by the motor into a sliding movement. used for

The switch used is preferably a changeover switch designed as a microswitch, which is connected to the motor of one component and can optionally be connected to the motor of another component.

In other words, the switch serves to control the motor in both directions of movement and is directly electrically connected to the motor in the component.

In a further embodiment of the invention, the push rod protrudes movably from the casing, in which the slide member is slidably mounted and engages the switch, the motor and, if appropriate, the rack of the adjustment member. A matching transmission member is housed therein.

The housing thus serves to accommodate all the components that serve the function of control and adjustment elements.

That is, the components are housed compactly within the casing.

Further advantageously, the push rod part movable into the housing is surrounded by a bellows.

As a result, the movement of the push rod is not hindered by surrounding influences.

The invention will now be explained with reference to the illustrated embodiment.

In FIG. 1, reference numeral 1 designates a housing, from which a push rod 2, which corresponds to the switching rod of a conventional control element, protrudes from a side force.

The right end of the push rod 2 can be connected to a lock (not shown) for operating it and for operation by the lock.

The push rod portion that moves into the casing 1 is sealed by a bellows 3.

The push rod 2 ends in the housing 1 at a point where it is brought into engagement with an actuating member 4 of a switch 5 designed as a microswitch and a changeover switch.

The switch 5 is connected via electrical connection lines (not shown) to a reversible motor 6, which is also accommodated in the housing 1.

The motor 6 drives, via a gear transmission member 7, a rack 8 that is slidable coaxially with respect to the push rod 2 in an axial direction.

A rack 8 has a cylindrical portion 10 arranged therein in the axial direction.
Together, they form a sliding member 9.

The cylindrical part 10 of the sliding member 9 has a hole 1 in the axial direction of the push rod 2.
1 and is slidably supported in said hole 11.

A collar 12 integrally formed on the cylindrical portion 10 of the sliding member 9
In the sliding range of , the bore 11 has an enlarged portion 13 .

A stop member 14 provided in the push rod 2 projects radially into the enlarged portion 13 and can be released under the action of a force.

As is clear in connection with FIG. 2, the stopper member 14
are three radially slidable sliding members 15, 16, 1
The sliding elements 15, 16, 17 are pressed radially into the bore 11 by an annular spring 18.

The sliding elements 15, 16, 17 are obliquely beveled at the edges which protrude into the bore 11.

Said sliding member 15.degree. 16.17 is returned against the spring force by an external force if the collar 12 exerts a sufficiently large radial force on the beveled edge.

In the position of the push rod 2 illustrated in FIG. 1, the lock (not shown) connected to the push rod occupies the switching position "unlocked".

When the lock is operated by rotating the key introduced into the lock in the locking direction, the push rod is pulled to the right.

In this case, only a very small force needs to be applied.

This is because the push rod 2 can be moved within the bore 19 of the casing 1 without friction.

In this case, the sliding member 9 is not entrained.

The movement of the push rod 2 operates the switch 5 via the operating member 4, and the motor 6 is connected to rotate in the locking direction.

Similarly, all motors of other identical components (not shown) which are connected to said switch 5 are connected.

The components arranged in the other doors operate in the same manner as the components illustrated in FIG. 1 in a different working sequence.

The motor 6 of the component shown in FIG. 1 begins to rotate, so that it slides the rack 8 via the gear transmission 7 to the right.

The collar 12 therefore also initially slides to the right in the area to the left of the stop element.

Furthermore, the collar 12 is slid to the right within the still fixed push rod 2 until the collar 12 is pressed against the stop member 14.

This position is illustrated in FIG.

If the collar 12 continues to move to the right, said collar 12 carries the stop member 14 and thus the push rod body to the right.

During this phase of movement, the locking mechanism of the lock (not shown) is actuated in the locking direction by means of the push rod 2 until the collar 12 travels together with the stop member 14 a distance corresponding to the locking stroke.

However, the sliding member with the collar 12 is then slid further to the right, while the push rod 2 remains in the end position already obtained.

The push rod 2 now exerts a resistance to the axial movement of the collar 12 via the stop member 14, so that the sliding member 15 of the stop member, via the beveled edge of the collar 12,
16.17 is pushed by an external force in the radial direction.

The collar 12 is therefore slid to the opposite side of the stop member 14.

This stage of movement is illustrated in FIG.

Said movement ends in the position illustrated in FIG. 6 in which the switch 5 is actuated via the actuating member 4 to shut off the motor 6.

The lock occupies the switching position "Lock J" because the push rod has already reached its end position.

In the position of the push rod and sliding member shown in FIG. 6, when the door is newly unlocked by turning the key in the unlocking direction, the push rod is easily moved to the left;
This causes the switch to be operated again.

The motor is thereby connected in the opposite direction of rotation to the operating phase described above.

In this case, the operating distance of the switch is 6th in the sliding direction.
It is smaller than the gap formed between the collar 12 and the stopper member 14 in the figure.

When the motor 6 is connected by the switch 5,
The sliding member 9 begins to slide to the left, but in this case, however, initially the push rod 2 is not carried away, and then the collar 12
contacts the stopper member 14 from the left.

The push rod 2 and the sliding member 9 are then pulled together to the left through the locking stroke until the locking mechanism of the lock is unlocked again and the push rod reaches its left end position.

The collar 12 then slides over the stop member 14 to the opposite side of the releasable stop member 14 under the action of a force and again obtains the position of the collar 12 and sliding member 9 as in FIG. Proceed a different distance corresponding to the journey.

Since each operation of the switch 5 controls the motor of another component unit in the same way as the motor 6, the first
A door with the component shown in the figure allows other components to be operated in the same way at the same time.

Since relative sliding is easy and the sliding distance is short until the switch 5 is operated, the lock can be locked or unlocked without applying significant force when turning the key.
