Description

FIELD OF THE INVENTION

The The invention relates to a manual locking device for the crank height adjustable vehicle window. The locking device can hold the window in any position. It preferably points in the drive crank of the window lifting mechanism a locking bolt on, which actuates a cam or the like when turning and this one gear lever is offset so that the window thrust crank is not more works. The invention further relates to the propulsion crank for a window lift mechanism and in particular a manual locking device for the rear windows. Furthermore, the invention relates to motor vehicles with a manual Lock the rear window.

STATE OF THE ART

Detents for window lifts are intended in motor vehicles Normally block the windows so that you can not lift them anymore or lowering can. Own vehicles with power windows usually a locking mechanism for the rear windows, so that the passengers can not operate them. This mechanism is mostly located near the driver's seat, For example, in the form of a button, which when pressed the Power supply to the devices in the rear doors interrupts. The lifting mechanism will stop working and the rear windows can only be opened by the driver of the vehicle and closed.

The Electric window lock is required for safety reasons. By the lock of the rear window one can children on the opening prevent the windows from being in danger, for example by holding out an arm of the vehicle during the Ride or by picking the hands or fingers while Close the windows.

The Locking the rear window can also help prevent people throw objects into the vehicle from outside or that inmates throw things out of the vehicle in the back seats. This prevents possible pollution or a loss of valuables, if children or Rider throw something out of the vehicle.

Although this locking mechanism in vehicles with power windows works, it is of no use if the lifting and lowering of the Rear window done by hand with a crank or a handle. There is therefore a need for a mechanism with which to do the manual Lifting and lowering the windows can prohibit. Thus let to increase the safety of passengers and those mentioned Avoid risks. Most vehicles with a manual power window mechanism and a crank but have no mechanism for a Blocking the window lifting function.

The GB 974,913 discloses a crank for opening and closing vehicle windows. The crank can be brought from a working position into a functionless. The change takes place with the help of a cylinder lock and a key-operated latch part whose projection moves a pin. For switching the crank from the working position to the non-functional, it is raised and moved the pin with the locking device down so into a recess in the head part of the crank that he blocked it in this position. To bring the crank back into the working position, the pin is lifted with the locking device, which then allows the crank to rotate. Then the windows can be raised or lowered again.

you Although it allows the rear window in a particular position lock, but you need a key and a castle, and you always need the same key, Do you want to release the rear window again. The key becomes an essential accessory in the vehicle is to be kept and that must not be lost. Is the key at the same time the vehicle ignition key can the windows are only locked and released when the engine is switched off which would be another disadvantage. Also, the crank wear out, she is constantly between one Working and a functionless position reciprocated. she can loosen, and arises when lifting and lowering the windows a game and thus cracks.

The US 6,076,304 describes a locking system for crank-operated windows. The document discloses two methods for blocking the windows. The first is based on one or more V-shaped springs which allow the crank to be locked over indentations in the crank axle. The number of positions in which the crank can be blocked is identical to the number of wells in the axis. In the second method, the crank is attached to the base. A clamp engages in recesses which are located on the crank base and thus prevents their rotation. To release the window, all you have to do is lift the clamp away from the indentations, and the crank can then be used normally to raise and lower the window.

This document also offers solutions for detecting the rear window of a motor vehicle. However, the first method can not 100% prevent moving the windows, and it can lock only in predetermined positions. Although with greater power, the crank can still be turned. The second method requires clamps to lock the crank base to the recesses. If they are not needed, these terminals must be stored in the vehicle.

One often used, prosaic procedure, opening the Rear window to prevent, lies in the simple distance the crank. You can not do that window at all raise or lower. This procedure comes, for example, during prisoner transport used in police vehicles. But here is another one Store the component in the vehicle, namely the crank, and there is always the danger that it will be lost.

Although There are different procedures for a rear barrier Window in manual or crank mode, so represented The state of the art is a problem and there is a need for a locking device for manually height-adjustable vehicle windows, which is satisfactory, works and costs little.

OBJECT OF THE INVENTION

It Object of the invention, a locking device for To provide crank windows, which is a feasible and economical Alternative represents and costs little, with the windows in each Any position should be lockable without the crank wears and without having another accessory in the vehicle must keep.

A Another object of the invention is to provide a Driving crank for the window lifting mechanism in motor vehicles, which also contains a locking device, wherein the Crank no other window lifting mechanism required, but in each Window lifting mechanism should be integrated.

It is still an object of the invention, a motor vehicle with a manual determination for the rear windows to provide passengers with greater security offers.

BRIEF DESCRIPTION OF THE INVENTION

This is achieved by a locking device in the hand crank for height-adjustable vehicle windows, comprising at least one adjustment part and at least one transmission arrangement, which be coupled with a pinion axis of the window lifting mechanism can, wherein the adjustment and the gear assembly each other are assigned so that a movement of the adjustment on the Gear acts so that it selectively engages the crank brought about with the window lift mechanism or a release from that. Next is a propulsion crank for a motor vehicle window provided which via the invention Locking device features. Also, a motor vehicle is provided with at least one window comprising a hand crank with the Locking device according to the invention.

The Invention provides an economical, feasible solution for manual detection of the rear windows of a motor vehicle when lifted and lowered with a crank become. The device according to the invention blocks the back windows completely. The procedure is simple and does not require a key or special clamps. There is also no wear of the lifting device.

DETAILED DESCRIPTION OF THE INVENTION

In a preferred embodiment, the manual locking device is located 4 of the vehicle window in the propulsion crank 1 ( 1 ). 1 to 7 show the crank 1 without further details to the locking device according to the invention. The crank 1 includes a first end 10 , a second end 11 , a crank arm 3 , a handle 2 and a cover 16 (not detailed). The two ends 10 . 11 are connected via the crank arm and form its ends.

The locking device according to the invention 4 is located at the first end 10 the crank 1 which is that of the window lift mechanics 9 associated end is. This is located in the door of the motor vehicle (not shown).

The locking device according to the invention 4 is preferably under a cover 16 obscured so that the passengers can not see them. You can only use a locking pin 5 see with which the locking device 4 can be operated. If appropriate, it is possible to reduce the manufacturing costs of the crank 1 the cover 16 omit because it is not an essential component of the locking device according to the invention.

The handle 2 is preferably located at the second end 11 the crank 1 which is the first end 10 is opposed, and allows the vehicle occupant seizure. The handle 2 can rotate around the longitudinal axis, which is a use and turning the crank 1 when raising and lowering the window easier. One then does not have to twist the wrist, which could make it harder to use the crank. The crank arm 3 between the ends 10 . 11 acts when turning the crank 1 as a lever, allowing the user to crank 1 effortlessly with only a small movement of the arm. The leverage results from the distance between the handle 2 and the first end 10 to that the crank 1 is turned.

The crank of the invention 1 can in all vehicles for the window device 9 they only need to be compatible with their respective windows hoist 9 be. Since there are no requirements for size and shape, the crank of the invention 1 replace the existing cranks for the lifting windows in all existing vehicles. This allows the owners of vehicles to retrofit with a window lock without the window lift 9 in the vehicle must be changed.

The locking device 4 ( 8th to 13 and 16 to 20 ) has an imaginary axis X, which is the orientation of the crank arm 3 defined, and an imaginary axis Y, which defines the axis about which the crank 1 rotates. The axis Y is perpendicular to the axis X. The locking device 4 has a locking pin 5 or the like, which is aligned in the imaginary axis Y, and whose free end is an adjustment part 6 includes, such as a cam or the like. It can have any shape. Preferably, a cam is used, because of their advantageous technical properties.

The locking pin 5 and the cam 6 are preferably located at opposite ends of the part. In another preferred form, they are separate parts that are operatively connected to each other such that movement of the locking pin 5 also the cam 6 emotional. In 9 . 10 and 12 is the crank 1 with the locking pin 5 to see while 8th . 11 and 13 the same crank 1 show with a direct top view of the cam 6 ,

The locking device 4 preferably comprises a guide pin 15 which is eccentric to the Y axis. It is preferably in the section opposite the locking pin 5 , Preferably, the axis Y, the guide pin 15 as well as pen and cam 5 . 6 arranged on a line ( 8th . 9 and 17 . 18 ).

The locking device according to the invention 4 preferably comprises a spring 14 and a gear arrangement 7 , preferably with a first crankshaft 12 and a second crankshaft 13 , For a better graphic representation of the locking device according to the invention was in the 8th to 13 . 17 and 18 the cover 16 omitted.

In the first preferred embodiment of the crank 1 ( 1 to 14 ) are the crankshafts 12 and 13 semicircular or crescent-shaped, each with a pinion engagement 17 also in a semicircle. The crankshafts 12 and 13 are arranged so that they are at one end on the guide pin 15 overlap and that both pinion interventions 17 Opposed to open, form a perfect tooth circle that extends around the pinion axis 8th the window lift mechanism closes. Are the crankshafts 12 . 13 functionally associated with each other, the two pinion engagement form a pinion opening which the pinion axis 8th the window lifting mechanism includes.

In the second preferred embodiment of the crank ( 15 to 20 ) are the crankshafts 12 and 13 not semicircular, but triangular-shaped, with the semicircular Ritzeleingriffen 17 located in the hypotenuse. Despite the geometric differences, the second embodiment works the same as the first.

The assignment by the guide pin 15 done so that the crankshafts 12 and 13 firmly on the crank 1 stay and be able to shoot with her at the same time.

In the inactive position of the locking device 4 (in which the crank 1 can move a window) enclose the crankshaft 12 and 13 with their pinion interventions 17 the pinion axis 8th the window lift mechanism 9 , Will the crank 1 then moved, so the pinion axis moves 8th with (due to the pinion axis and levers form engaging) and the window lift mechanism 9 is pressed. You can then raise and lower the window.

For the activation of the locking device, so that the crank 1 the window can not move becomes the locking pin 5 pressed and the cam 6 turned. By turning the cam 6 be the crankshaft 12 and 13 pressed apart, so that their pinion interventions 17 no longer with the pinion axis 8th intervene and the crank 1 no longer with the window lift mechanism 9 connected is. So no play around the axis of the locking device 9 arises around, it is further preferred that the first end 10 over an extension 18 along the axis Y, which lays around the axis towards the vehicle door.

To release the device, it is sufficient to move the cam with the locking pin, so that the crankshafts 12 and 13 move back in opposite directions, and so they return to the pinion axis 8th include.

If the locking device is activated, can over the crank 1 the window can not be operated, and the vehicle window is locked in a simple, effective and economical manner, without the window lifter 9 must be changed. Thus, the window can be locked in any vertical position, where it is when the cam 6 is moved. 8th shows the crank 1 if the cam 6 just the crankshafts 12 and 13 pushes away and how the device prevents height adjustment of the vehicle window.

With the spring 14 can the locking pin 5 the locking device 4 only be moved when a force acts, which is the spring 14 deformed. The feather 14 ensures that when activating the locking device 4 the crankshafts 12 and 13 from the pinion axis 8th Stay away. Thus, the window can not by a violent movement of the vehicle or by a child who tried the locking device according to the invention 4 to be solved. It is achieved a higher safety for the occupants of motor vehicles when the windows with a crank 1 be actuated, which is a locking device 4 having.

In the first preferred embodiment, the spring 14 crescent-shaped and it has a depression, which protrudes into a portion of the cam 6 engages ( 14 ). In the second preferred embodiment, the spring 14 spiral and separate the pin 5 from the cam 6 , Accordingly, pen are 5 and cam 6 arranged on a line, and the spiral-shaped spring 14 is in between ( 19 and 20 ).

Is the spring 14 in rest position, so is the locking pin 5 from the cam 6 separated and can rotate freely. A turn of the pen 5 does not transfer to the cam 6 , So the cam 6 can be rotated, the pen must 5 in the direction of the cam 6 be moved until he touches them. Preferably, this happens by an opening at one end of the pin 5 in a protruding part of the cam 6 intervenes. At the same time, the pen needs 5 be turned so that the cam too 6 turns. This will compress the spring. As soon as the pin is no longer under pressure, it is released from the spring 14 pushed away from the cam and the cam 6 stays in the initial position. So the cam 6 Once again, the procedure described above must be performed, but so that the pen 5 rotated in the other direction.

In the second preferred embodiment, the pin and cam are separate parts that can interlock. The locking pin 5 can be rotated by a sharp object that fits into its surface. This achieves a rotation that can block the window. There is thus no need for special accessories for the activation of the locking device 4 and no further accessories need to be stored in the vehicle. Preferably, the locking device can be operated with any key, for example the ignition key. In this position, turning the locking pin 5 for actuating the locking device 4 in either direction (clockwise or anti-clockwise) since there is no predetermined definition as to the correct direction of rotation for actuating the locking device 4 is.

Although in a preferred embodiment of the invention the locking device 4 through a locking pin 5 or the like is activated, the locking device 4 be activated by other means. Only the one cam has to be moved, which locks or releases the crank window.

The locking device according to the invention for crank windows is located only in the crank 1 and it does not affect the structure of the window lift mechanism 9 , Thus, it can be incorporated into any manual window lift mechanism of vehicles, regardless of the size of the window or the number of crank turns required to fully raise or lower the window. So there is no need to change the window lifting mechanism, which also the locking device 4 considerably more expensive and thus their use in existing motor vehicles.

to Invention includes the lockable crank described above for driving the window lift mechanism in motor vehicles.

to Invention also includes motor vehicles with window regulators, having a crank as described above, or a locking system according to the invention. In short, vehicles with a lockable crank as described above.
