Description

FIELD OF THE INVENTION

The Invention relates to car window side shutters, which are raised and lowered with a hand crank, and which allow the window to be locked in any position. The The invention relates in particular to a hand crank for the Propulsion of the window lifting mechanism, which contains a locking device. The invention also relates to motor vehicles with a manual Window lifting mechanism and a locking device for this.

STATE OF THE ART

Under Locking device is related to the handling of the vertical Lifting window understood every form of blockade through which the up and down Lowering the car window is prevented.

vehicles usually own with an electric window lift a barrier by which you can prevent them from the others Vehicle occupants is actuated. This mechanism is located usually close to the driver's seat. It is usually a button that prevents in the pressed state that the window devices in the back doors respectively be supplied with electric current in the passenger door. The Electric windows are then disabled and the windows can only be adjusted by the driver.

The Electrical window detection is required for security reasons. By blocking the discs you can prevent children from open the rear window and put yourself in danger can. For example, by a Rausstrecken the arms from the moving vehicle or by joining hands or Fingers when closing the windows.

By the lock of the rear side windows can continue to be prevented be a stranger from outside an object in Throwing the car or taking something out of the car. Also can Riders on the back seats no objects throwing out the car window, not just roads and paths waste, but also lost valuables can. For example, if children or other vehicle occupants are easy throw something out of the vehicle.

A such lock works only on vehicles with electric operated window lifting devices. It is not suitable for lifting windows, manually with the help of a crank or a button can be opened and closed. It exists therefore, there is a need for a device for raising and lowering can lock from hand-confirmed windows and the higher one Occupant safety by eliminating the aforementioned sources of danger allowed.

A large number of vehicles still owns manual, crank operated window opening and closing devices, but no blocking system that allows you to raise and lower the windows can prevent. Barrier solutions are in various publications described.

GB 974,913 generally describes a winch for window propulsion in a vehicle. The hand crank can be brought from an operating to a rest position. The position change is achieved by using a locking key a locking cylinder operated, which moves a pin over a nose. To change between operating and rest position you have to turn up the crank handle and bring him to the rest position. Upon actuation of the lock key, the bolt is moved down, engages in a recess of the lever body and then locked in this position. The hand crank is returned to operating mode by turning the lock key again, raising the bolt and releasing it again so that the vehicle windows can generally be reopened and closed.

These Although Scripture teaches a solution for blocking the rear side windows in a certain position, the proposed Device requires for their operation but a locking key and you always have to the same key for unlocking the rear side windows have at one's fingertips. This is the key in this attachment to another important item to keep in the vehicle interior is and you can not lose under any circumstances. Is the lock key the ignition key itself, the window can only locked and unlocked when the car is standing, which is another Disadvantage of the proposed system is. In addition, at the in The British system always described the crank handle between Move the operating and the rest position, so this one Wear is subject. The hand crank is at the many Window opening and closing operations always looser.

US 6,076,304 generally describes a locking system for windows that are opened and closed with a hand crank. The document describes two types of window lock. In the first two or more V-shaped springs are used, which lock the hand crank by means of recesses, which are arranged around the axis (embedding). The number of positions in which the hand crank can engage corresponds to the number of recesses which are about their axis are arranged. The second uses a clasp to attach the hand crank to its base. The clasp cooperates with dimples located on the crank base and limits their movement. If the window is unlocked, it is enough to pull the clasp out of the recesses of the base, the hand crank is so free for their normal functions, namely the opening and closing of the window.

The first variant with the V-shaped springs does not prevent completely opening the window. It will be in certain fixed positions. The second proposal variant requires a clasp, which in recesses at the base of the hand crank can intervene. It must therefore the clips in the vehicle be kept when not in use, so the windows are not locked.

alternative you can open and close the windows Simply prevent the crank handles for the side rear window removed. This is a very common one Method. For example, police vehicles have no window cranks at the rear, so that those arrested can be transported safely. Again, you have an additional item inside the vehicle carry along, in this case a crank handle, and it exists always the risk of losing it.

 Although There are different ways to lock the side rear windows in vehicles, these are by means of hand crank or button open and closed, so are all the solutions mentioned problematic in its implementation and application. They are not satisfactory and they do not fix the problem of how to really crank windows can lock.

the The invention offers a simple and cheap Way how to disable the winch for car lift window can. The mechanism according to the invention allows a simple and complete locking of all individual Window of a vehicle without getting a key or special clips for this needs. The inventive Mechanism also avoids unnecessary wear of the Crank mechanism, and with it that at a normal opening and closing the window becomes loose.

The inventive system is suitable for every vehicle that has crank-operated lifting windows, because it only changes the hand crank itself. The propulsion blocking system Can be installed in the car without making big changes on the window lift mechanism must make. The installation of the locking system in the vehicle is easy. You just have to go through the window crank a hand crank with the locking device according to the invention replace.

There it is a simple system and you do not change the window lift mechanism must, the system of the invention can also as Accessories sold for retrofitting vehicles become.

The Locking device for car crank window is not suitable only for the rear side windows, but also for the passenger or even the driver window. It can all Crank window of the vehicle to be locked. As it is an individual Locking system is the subject of the invention allows the motorist the choice of which windows should be blocked. To have to yes not all windows are always unlocked and unlocked at the same time.

The Locking device can be activated at any time, without that you need special tools for the implementation. This will prevent you from getting more items like keys or clips inside the vehicle must be ready. The blockage The window does not necessarily have to be done when the windows are completely closed closed or opened. The windows can be locked in any open position.

DETAILED DESCRIPTION OF THE DRAWINGS

1 shows a preferred embodiment of the invention. The locking device 4 for the manual propulsion of the window is located in the hand crank 1 for propulsion.

The 1 to 9 show the winch 1 with the locking device according to the invention 4 , The crank 1 preferably has a first end 10 , a second end 11 , an arm piece 3 , a handle 2 and a bulky body or shell 16 , The first and the second end 10 . 11 are through the arm piece 3 connected to each other, and in practice, those are the ends.

The locking device according to the invention 4 is closer to the first end 10 the winch 1 and this is the end associated with the window lift mechanism. The window mechanism is located in the vehicle door. Door and window lift mechanism are not shown in the drawings.

The locking device 4 is preferably of the three-dimensional body 16 surrounded so that it is not visible to the vehicle occupants. Only the locking pin 5 and a knob 13 for the operation of the locking system 4 are visible.

The handle 2 is preferably located at the first end 10 opposite second end 11 the winch 1 and is designed to fit in the hand of the vehicle occupant. The handle 2 can turn around itself and thus helps the operator to turn the hand crank 1 if he wants to open or close the window. The operator does not need to turn his wrist, which would make the operation of the window advance difficult.

The movement of the handle, of course, causes the entire crank to turn about the first end 10 ,

The arm piece 3 between the first end 10 and the second end 11 has such a length as a lever for turning the hand crank 1 necessary, so that the vehicle occupants the crank 1 easy to turn, only by a simple effortless arm movement.

The crank of the invention 1 suitable for all window mechanisms and for all vehicles. The connection only has to be done with the window mechanism compatible with the vehicle in question. Since there are no changes in shape or use, the crank of the invention 1 Replacing existing cranks on vehicle lift windows so that even windows in vehicles that are already delivered and in use can be retrofitted without the owner having to replace the window lift mechanism.

In a first embodiment of the invention, the locking device comprises 4 a virtual axis X defined by the longitudinal direction of the arm piece 3 , and a virtual axis Y, defined by the direction of the axis around which the hand crank 1 rotates, wherein the axis Y is perpendicular to the axis X. Aligned to the virtual axis Y comprises the locking device 4 a locking pin 5 or the like, the free end of a bar 6 has.

The locking pin 5 and the latch 6 are preferably located at opposite ends of the same part. Otherwise, the locking pin 5 and the latch 6 Preferably, different parts that cooperate with each other, that is, a movement of the locking pin 5 also moves the latch 6 ,

The locking device according to the invention 4 preferably comprises a set of springs 7 consisting of two springs, of which a first spring at one end of the knob 13 At the other end, hit the tongue ring 14 , The second spring hits the other side of the tongue ring with its ends 14 and the support 20 that with the tooth axis 8th the window mechanism 9 cooperates. The ring 14 is located between the adjusting knob 13 and the support 20 and cooperates with the tooth axis 8th , which is axially displaceable to the axis X. The ring 14 includes a toothed opening 17 , assigned to the tooth axis 8th , and preferably a fitting 15 , assignable to the bolt 6 so that the latch 6 through the locking pin 5 can be operated.

In the working position of the locking system according to the invention, that is, when the crank 1 can not lift the window, the bolt remains 6 in a position parallel to the tongue ring 14 so he is not on the tongue ring 14 seated.

In this case, the second spring exerts a force on the ring 14 out, which means that the ring from the tooth axis 8th is kept away and close to the adjusting knob 13 located. Then has a turn of the winch 1 no influence on the window mechanism 9 because of the ring 14 for the movement of the tooth axis 8th is responsible (due to its embedding between the teeth of the axle 8th and the toothed opening 17 ), so the crank 1 is ineffective (she is free). 2 and 3 show the working position of the locking system.

In other words, the tongue ring does not cooperate with the bolt, it does not engage with the connector 15 one, leaving the tongue ring 14 by the force of the second spring from the tooth axis 8th is pushed away.

To deactivate the device 4 that is, to move the window, the user must move the knob 13 Press with a force greater than the spring force of the two springs, compress them, and the ring 14 with the tooth axis 8th bring an intervention. When the button is pressed 13 turns the locking pin 5 with and moves as already mentioned also the bolt 6 , The movement of the bolt 6 is necessary for him to enter a cooperative position. To deactivate the locking system 4 you have to have a corresponding force on the knob 13 exercise, and the locking pin 5 rotate.

In cooperative position with the ring 14 the latch engages 6 one with the connector 15 and holds the tongue ring 14 with the tooth axis 8th together, giving the force of the associated spring 7 has no effect and the ring 14 from the axis 8th stays pressed away. After turning the bolt 5 becomes the button 13 released, and since the button is hit by the first spring, it returns to its original position, and also the second spring can the tongue ring 14 because of the bolt not from the tooth axis 8th Press away. The ring 14 , now with the latch 6 connected, remains with the axis 8th in contact, so with the crank 1 the vehicle window can be moved up and down.

The 4 and 5 represent how the deactivation of the locking system 4 he follows. The 6 and 7 show the deactivated mode of the locking system 4 in which the window by pressing the crank handle 1 can be moved.

To operate the locking device 4 you move the locking pin 5 (you have to push the button 13 do not press), therefore the bolt 6 rotates. It is thus prevented with the crank 1 the window is moved. The bolt 6 is moved until it is removed from the fitting 15 that is, until it settles in a non-functional position opposite the ring 14 located with the extensions. Because the bolt 6 no longer because of the assembly 7 the movement of the ring 14 inhibits, this is from the axis 8th pushed away again, namely the knob 13 out, so that a movement of the window is prevented. The locking pin 5 must be for actuation of the locking device 4 easy to be moved.

When pressed, the propulsion crank 1 the window lifter with the locking device is freewheeling, so that it is out of order, and thereby the windows of the motor vehicle Locked in a simple, efficient and cost-effective manner, without having to change anything about the lifting mechanism. This allows a total of a lock of the window in each position in its vertical path and from the time at which the bolt 6 was moved.

The locking pin 5 can be rotated with any pointed object that fits into the surface and rotated as needed when the window is to be locked. There is therefore no need for a particular tool for operating the locking device 4 so that you do not have to provide any additional tools for its operation inside the vehicle. The locking device 4 is preferably operated with the ignition key of the motor vehicle. In this design, the locking pin 5 for actuating the locking device 4 be rotated in both directions (clockwise or counterclockwise), so that it is in terms of the correct direction of rotation for operating the locking system 4 there are no specifications.

In a preferred embodiment of the present invention, the barrier device uses 4 however, a locking pin 5 or similar. In the locking device 4 For example, other types of drive may be used, such as a screwdriver or any other solution, provided that the tongue ring is actuated by its actuation 14 is moved, since this is responsible for the lock or unlock the Autohebefensters.

The locking device 4 for car windows, their window mechanism by means of a hand crank 1 is actuated, affects only the propulsion crank 1 They are therefore used in all manual window lifting systems of automobiles, regardless of the size of the window or the number of revolutions of the crank handle necessary to fully open or close the window. This feature means that you do not have to change the window lifting mechanism and that you avoid changes, which costs high in the locking device 4 require.

These would be their use in motor vehicles, which already are in operation, prevent and possibly impossible do.

The invention also provides a crank handle for operating lifting windows in motor vehicles, which is provided with the above-described manual driving lock 4 Is provided.

The Invention also provides a motor vehicle with a window lift system in which the above-described crank handle or the Crankshaft lock is used.
