Description

VEHICLE DOOR FOR ARMOURED VEHICLES Description

The invention is concerned with a vehicle door which has in addition to a door latch at least one mine protection bolt. Doors of this kind have a device for a rapid opening as well as a device for assistance during opening and are in practice termed in their double function as brake devices.

From DE 10 2008 039 509 A1 a vehicle door is known which is characterised in that the opening/closing of the door as well as the releasing/locking of a mine protection bolt as well as the actuation of a brake device are undertaken by a single handle. This is thereby to prevent the case where a person does indeed actuate the door as well as the brake device, but then through inattention does not actuate the handle for locking the mine protection bolt so the complete protection against mines or other threats is not provided. This solution enables a so-called single-handed actuation. Even if a single-handed operation is frequently desired this solution does have however the disadvantage that it is liable to breakdown. More particularly in the case of an opened door and inserted mine protection an undesired closing and thus associated undesired negation of the mine protection is not ruled out.

The object of the invention is to design a vehicle door of the aforementioned kind so that an all round function of the door as well as a safe actuation of the mine protection bolt is guaranteed.

This is achieved through the features of patent claim 1. Advantageous developments are provided in the dependent claims.

The invention is based on the idea of undertaking the opening of the door by a lever etc. and by releasing and closing the mine protection bolt and thus linked therewith the associated braking and damping device by a further lever or handle. The mine protection and the door opening/closing support are thus indeed actuated with one lever or handle, but the door opening itself is undertaken with a separate device. It is thereby ensured that the door can only be opened when the mine protection bolt has been unlocked since only then is the device supporting the door opening released. It is furthermore proposed that the door latch can be locked by the mine protection bolt. The locking or engagement of the door latch in the door lock can on the other hand also take place even when the mine protection bolt is not yet engaged in the door pillar or door frame of the vehicle.

By separating the actual door opening from the brake device the position of the mine protection bolt itself is better considered so that the entire closing and opening system of the door can now be tuned predominantly to the mine protection bolt. The door itself need not be held with a second hand in order to prevent opening of the door by the brake device, if the mine protection bolt has not been unlocked, since the brake device is blocked in this case. The design thus allows a single-handed operation - with only one hand.

The handle for opening the door is in a preferred design similar to that of a lever which is to be pulled to and is known from the civilian area. Thus connected therewith, even if only a small advantage, is the fact that the opening of the door for a vehicle driver or passenger involves the known customs when opening vehicle doors. The lever can obviously also be designed as a lever which can be swivelled in plane. Alternatives are likewise conceivable.

In a preferred design the second handle for unlocking/locking the mine protection bolt is automatically guided in a guide so that it cannot undertake any other movement. The movement of the lever is hereby preferably pivoting parallel to the vehicle door downwards or upwards out from a normal position. The handle can in turn be held by means of a further damper in its lower end position as well as in its normal position. The guide is in turn preferably incorporated in the reinforcement against lateral blast/shock.

During closing more particularly from outside it is ensured that this cannot happen when the mine protection bolt is inserted.

The invention will now be explained in further detail with reference to an embodiment illustrated in the drawings. The drawings show:

Figure 1 a plan view of a vehicle door with a retracted mine protection bolt,

Figure 2 a recess for the second handle,

Figure 3 a combination of Figures 1 and 2,

Figure 4 a plan view of the vehicle door of Figure 1 with an inserted mine protection,

Figure 5 the vehicle door with door trim.

Figure 1 shows a vehicle door 1 with a safety window 2 (not described in further detail) for an armoured vehicle (not shown in further detail). The vehicle door 1 has a handle 3 - as door handle 3 - for opening the door 1 as well as a further handle 4 - as protection handle 4 - for unlocking and locking one or preferably even two mine protection bolts 5, 6 and pulling to the door 1. The first handle 3 is preferably spring-loaded and imitates a civilian handle. The second handle 4 can be pulled, pushed, pressed or moved or pivoted in another way. In the design here the handle 4 can be moved or pivoted parallel to the vehicle door 1. The handle 4 is thereby preferably guided in a recess 11 with guide 15 (Figure 2). 16 designates the door cover, as is known from the civilian field.

The first handle 3 is mechanically coupled to a so-called door opener system or door lock 7. The second handle 4 however is mechanically connected to the two mine bolts 5, 6 and can be fixed in both of the end positions by a damper 8. At the same time the second handle 4 is connected by a rod linkage 10 to a brake device 9 - here a damper system - which is responsible for opening the door 1. The handle 4 itself has a spring which presses the handle 4 into the normal position or normal setting which also serves for assisting the actuation of the handle 4.

The rotational axis of the door 1 is marked by 12. A preferably textile material 13 determines the end stop of the door 1 wherein the opening angle for the door 1 can also be adjusted by this band 13 etc. which could happen by way of example by a slide (not shown in further detail) with detent catches.

Figure 3 shows the door 1 of Figure 1 with an incorporated recess 11 of Figure 2. Figure 4 shows the closed door 1 with the inserted mine protection bolts 5, 6 (without recess 11).

Figure 5 shows the door 1 in a view from outside. The door 1 has for closing the door 1 from outside a “gear cluster” 14 whose function will be described below.

The interaction of the individual structural groups will be explained in further detail based on the drawings.

The protection handle 4 is located (pressed by a spring) in the normal position or normal setting, the mine protection bolts 5, 6 are retracted, the piston rod of the damper system 9 is released. To open the door 1 the door handle 3 is pulled to. Connected with this the door opener in the door lock 7 is released, the door 1 is released, the opening of the door 1 is assisted by the released piston rod. The opening angle of the door 1 is restricted by the textile band 13.

To close the door 1 the damper 9 is switched over by the action of the protection handle 4 and a unit 17 so that the damper 9 can now be pulled to. In the simplest variation the protection handle 4 is held or pulled to (with the door 1) until the door 1 has engaged in the door lock 7. This avoids the case that the damper 9 is switched over again and the door 1 can be opened again during the closing of the door 1. After the engagement of the door lock 7 the protection handle 4 is moved or rotated downwards inside the guide 15 so that the mine protection bolts 5,6 are engaged.

If as shown in Figure 4 the mine protection bolts 5, 6 are however still in their extended position, opening of the door 1 is not possible since the protection handle 4 which is responsible for releasing the mine protection bolts 5, 6, is locking or supporting the door lock 7 and therefore does not release it. The protection handle 4 must correspondingly first be guided into its normal position so that the door lock 7 can be released by actuating the door handle 3.

The closing of the door 1 with the inserted mine protection is also not possible due to the design of the door 1. It is thereby not a question that the mine protection bolts 5 and 6 projecting from the door 1 prevent such a closing, but that with projecting mine protection bolts 5, 6 the actuation of the damper 9 - from outside as well as also from inside - is blocked. If by way of example the gear cluster 14 is pressed from outside in order to close the door 1 then the door cannot be moved since the damper 9 is blocked and a closing of the door 1 is not possible (and not supported by the damper 9). Closing by a person located in the vehicle is likewise not possible since the protection handle 4 is in the guide 15 and the protection handle 4 cannot be used for closing the door 1. Furthermore in this position the damper 9, as already mentioned, is blocked.

An emergency opening is ensured in that even if the mine protection has been inserted the protection handle 4 can be brought from outside from this end position into the normal position by means of a spanner, socket wrench or the like.
