Description

The The invention relates to a power window for security vehicles, the equipped with armor plate constructions and quick-release systems is and from a servomotor, power transmission and guide elements as well as an emergency closing device consists. Such technical solutions be in the automotive industry for the production of security vehicles needed.

at The production of so-called safety vehicles are window lift systems needed which differ from those used in series production. You need to not just the heightened Masses of safety glazing can move, but beyond designed to be much more robust to the lock security to be able to guarantee even with occurring tilting. Especially need such power window devices for the so-called emergency closure.

The state of the art reached so far can be read from various publications. That's how it describes DE 195 10 943 C1 a lifting device for heavy bulletproof glass in motor vehicles, which moves the bulletproof glass in guide rails by means of lever system and angle joints, wherein the at least two Hubzahnräder are equipped with counter-rotating electromotive drives. The disadvantage of this technical solution results in particular from the large space requirement, which is available only to a limited extent because of the larger volume components of the outer contour of the security vehicle compared to standard sedans almost unchanged geometry. A quick-release routine with sufficient short-term effect is not feasible with this system.

A similar solution will be used with the DE 101 63 386 A1 made known. The window regulator described there is also equipped with a linkage system which is connected to a servomotor. The system is equipped with an emergency control device. Essential elements of Notstelleinrichtung are a power storage and a releasable coupling connection between the servo motor and the linkage system.

The Geometry of the linkage system is primarily the closing path the vehicle window determined.

The associated lever systems require comparatively large-volume components both for the actuator and for the emergency closing device. Finally, in the DE 41 08 190 C2 described the side part of a motor vehicle in special protection version, which contains a safety glazing. The lever mechanism used here consists of a gear transmission and a coupled thereto pivot arm, wherein the drive is arranged on one side in the window slot and fixed to the vehicle panel designed as a special protection panel. This technical solution does not have the prerequisites for the realization of an effective emergency closing routine.

The Disadvantages of the known technical solution thus exist in particular in the required space for the robust movement mechanics for the required Armored glass. About that In addition, generally lacking in such technical solutions fast-acting Notschließeinrichtungen.

The The object of the invention is therefore to create a technical Solution, with their help the defects overcome the prior art can. In particular, a system is needed in spite of the simple and robust function of the emergency closing device already integrated. Furthermore, in comparison to known Systems require less space for the locking mechanism to be used to be required. The aim is still a simple design as a condition for the cheaper Production. About that in addition to guaranteed can be that a violent downward movement of the disc after successful emergency closing safely prevented.

The The object is solved by the features of claims 1 and 2. The advantageous embodiments are described in the subclaims.

After that consists of the power window for Security vehicles equipped with armor plate constructions and with Quick release systems are equipped, from a servomotor, from power transmission and guide elements as well as from an emergency closing device. The servomotor is positively locked both with a gear element and with the door construction in connection. The transmission element is preferably a winch.

When Energy storage for the quick release serve springs guided on guide elements, against the force of the safety disc with the help of the servomotor open becomes. The guide elements are preferably telescopic rods or management staffs that positioned at least approximately parallel to the disk plane and in the closing direction the disc are aligned. The safety glass itself is located in a disc holder, with the winch through a Pull rope is in communication.

A particular embodiment provides in the closed state of the vehicle window, the pressure springs guided on guide elements are arranged in the relaxed or partially pretensioned state. In the opened state of the vehicle window, the pressure springs guided on guide elements are arranged in a largely tensioned state.

Of the Actuator is with a detachable Brake and / or with a mechanism for the interruption of the mechanical Connection equipped. These devices are available with the emergency locking system in connection.

Intended is also that in at least one end position of the safety disc on the disc holder a tail end damper is arranged.

to warranty the emergency closing function is Schnellverschlusswirksam on a component a remotely controllable release device arranged, for example, for decoupling the traction cable from the disc holder.

At the disc holder is in the upper end position of the vehicle window a mechanical locking device for the closed vehicle window arranged. This surely prevents the violent opening of the Vehicle window after locking.

It is possible, in place of the winch as a transmission element to arrange a spindle rod, which in turn is driven by the servo motor and with the disc holder communicates.

When guide elements are preferably positioned parallel to the disk plane and in the closing direction the disk oriented components, such as slide rails, guide cables, guide lever and the like.

The Advantages of the invention are summarized in that the Adjusting mechanism acts directly on the disc or on the disc holder. The weight of the disc is replaced by compression springs Use of traction devices, such as Bowden cable, scissor kinematics or levers, supported. When lowering the disc, these springs are tensioned. The for special protection vehicles absolutely necessary quick closure of the disc is done by Unlocking the drive and at least partial relaxation of the compression spring.

Of the End stop is ensured by limiting the spring travel. When using coil springs, the lowering of the windowpane along a curved Track through guide rods or telescopic rods within the coil springs.

Next the cost-effective Manufacturing is the novel system simpler, more robust and functionally reliable as the previously known systems. Although the emergency closing device already integrated, there is a smaller space requirement than in the known systems.

On simple way is at the same time a safeguard against the violent opening of the Washer secured from the outside after the quick release.

The Invention will be explained in more detail below with two exemplary embodiments. In the attached Show drawing:

1 a schematic representation of the power window with arranged between the door construction and disc mount spindle rod;

2 a schematic representation of the power window with arranged between the door structure and disc mount telescopic rods within compression springs.

Embodiment 1

According to the 1 There is a power window for security vehicles from a servomotor 1 standing at the disc pickup 6 for a vehicle window 11 made of bulletproof glass. About a flanged gearbox is the servomotor 1 with a spindle rod 9 in turn, in turn, as well as the two management staffs 10 , on the door construction 2 is attached. The servomotor 1 is equipped with a motor brake. At the guide bars 10 are preloaded coil springs 4 arranged. When opening the vehicle window by motor 11 become these springs 4 increasingly preloaded, making it as a power storage both for lifting the heavy vehicle window 11 for controlled closing as well as emergency closing for independent fast closing. In an emergency case, only the engine brake of the servomotor is remotely controlled 1 solved, so under the effect of relaxing compression springs 4 the disc holder 6 moved in the closing direction upwards. Alternative to the spindle rod 9 can the gearbox of the servomotor 1 also on a rack 8th attack. In this case, with the remote controlled release of the engine brake at the same time a locking pawl is activated, the disc holder 6 opposite the rack 8th locked in the closed position, causing the violent opening of the vehicle window 11 safely prevented from the outside.

Embodiment 2:

According to the 2 is a heavy vehicle window 11 with a disc holder 6 connected. In the lower part of the door construction 2 are both telescopic rods 5 and a servomotor 1 with attached winch 3 positively connected. At the telescopic rods 5 are compression springs 4 arranged, with the telescopic rods 5 within the compression springs 4 are located. About a pull rope 7 is the slide recording 6 with the winch 3 in connection. When closed, the compression springs 4 between the door construction 2 and the disc holder 6 already preloaded. When controlled opening the vehicle window 11 becomes the disc holder 6 with the help of the servomotor 1 , the winch 3 and the pull rope 7 with simultaneous additional loading of the compression springs 4 pulled down.

These are the fixation of the springs 4 serving telescopic rods 5 pushed into each other. The tensioned compression springs 4 serve when controlled closing the vehicle window 11 as energy storage for the support of the servomotor 1 when necessary lifting the heavy vehicle window 11 , In case of emergency, several options are available. Either in the case of the availability of a motor brake on the servomotor 1 solved this remotely. Alternatively, the clutch between the servomotor 1 and the winch 3 be solved remotely. Finally, the tow rope can also be remotely controlled 7 at the slide admission 6 or on the winch 3 copping. In all cases, there is a sudden relaxation of serving as energy storage springs 4 , so that the vehicle window 11 abruptly closes. Also, this embodiment of the power window for safety vehicles has only a minimal space requirement, so that the required arrangement can be accommodated problem-free between the voluminous vehicle outer skin and the inner lining while ensuring a high level of reliability. Due to the small components, the device is inexpensive to manufacture and assemble.
