Description

The invention relates to a lifting device in one Armored vehicle, with a holder, with one to be lifted Body, especially a grenade can be brought, and a driven lifting element, by means of of which the holder can be raised and lowered.

With tanks or armored vehicles it is to be achieved the highest possible combat strength, a larger one Amount of ammunition or grenades in a magazine. A grenade can be fired from the magazine either manually or with the help of so-called loading aids be fed. Because the grenades are relatively heavy is the manual lifting and moving of grenades not only very exhausting, but also in the long run little effective.

From EP-B-0 557 751, of which in the preamble of the claim 1 is a loading aid in the form an essentially vertically pivotable loading arm known who carries a holder that receive the grenade can. The loading arm can either be operated using a hydraulic cylinder or due to gravity in combination with a return spring can be raised and lowered, so that the grenade from the magazine is a gun attachment is feedable. To be taken up by the loading arm, the However, grenade in the magazine a predetermined position take in. This requires a rearrangement of the grenades in the Magazine and thus a constructively complex magazine structure, which is expensive. In addition, the Load arm not for any relocation of grenades inside the armored vehicle or a Record upright on the floor of the interior standing grenades can be used and therefore not flexible usable.

From FR-A-2 588 371 it is known to make grenades from a Reserve magazine by means of a lifting device in an immediate to transfer adjacent drum magazine. The The device comprises a fixed parallelogram linkage, that between a lower position, in one Grenade from the reserve magazine can be transferred to a holder is, and an upper position is adjustable, in which the grenade is handed over to the drum magazine can. Again, it is necessary that the means of Lifting device to implement grenades relative to this take exactly a predetermined position, otherwise they will cannot be included. An implementation of Grenades inside the armored vehicle is not intended and also not possible.

US-A-4 236 441 shows an armored utility vehicle, that has a shelf magazine in its interior for recording a variety of grenades and an associated one Storage and removal device having a Ceiling rail and a floor rail includes. In the rails a vertical mast is slidable, the one holding shell for a grenade is height-adjustable stores. By moving the mast sideways in combination with a vertical movement of the holding shell on Every single shelf can be approached to mast to take over the grenade contained there. With this too However, lifting device is not possible any Grenades, for example, in side compartments of the interior are stored, so that manually relocated these grenades in a conventional manner Need to become.

US-A-4 236 441 also shows a crane that is one has vertical support at the upper end Boom is attached, which supports a rope with hooks. The crane is used to rebuild the shelf magazine Frame vertically up through an opening in the armored vehicle to highlight. Such a crane is required a large installation space in the interior of a main battle tank is not available. In addition, the range the crane is limited by the length of the boom, so that it is necessary to extend the boom hydraulically to design, reducing the design effort however is very high.

A lifting device is known from US-A-4 904 142 Deck of a ship can be attached and do so serves to launch missiles or similar elongated objects an essentially horizontal position from above in to use vertical silos that are formed in the hull are. For this purpose, the lifting device comprises one Portal-like movable on two parallel floor rails Frame that consists of a substantially horizontal Alignment swivels into a vertical orientation is. The frame is essentially parallel to one another the support arm running in its horizontal Alignment includes the missile by means of gripping arms and together with this pivots into a vertical orientation. The support arm is on the portal-like for lateral adjustment Movable frame. To the rocket in its vertical Lowering the alignment into the silo or lifting it out, is the top of the missile over a rope connected to a winch mounted on the support arm, wherein however, the rope only works when the support arm is in its vertical orientation. This in the lifting device shown in US-A-4 904 142 is obvious for handling large and heavy elongated Bodies designed, the recordable missiles in horizontal position below the portal-like frame must lie. Use of such a lifting device in the interior of an armored vehicle is due to the required space is not useful.

The invention has for its object a lifting device in an armored vehicle with which especially grenades in a simple and flexible way can be included and implemented.

This object is achieved by a lifting device with the characterizing features of claim 1 solved.

By means of the swiveling, multi-part articulated arm a large area of the interior of the armored vehicle be painted over so that any grenade that is inside the pivoting range of the articulated arm is arranged with the lifting device according to the invention in a simple manner can be included. Since the lifting element is a rope, the user can make minor position corrections achieve a transverse deflection of the rope without the Articulated arm must be adjusted.

The articulated arm is freely cantilevered and in essentially pivotable in a horizontal plane. To one Grenade from the bottom of the interior of the armored vehicle the articulated arm in the horizontal plane pivoted into a position in which the rope is located essentially above the grenade. The rope preferably runs through the articulated arm and extends essentially at its free end vertically down. This is the vertical movement the grenade solely by the rope and the horizontal movement the grenade is determined by the articulated arm. This enables easy handling since the user the two motion components are independent of each other can execute and overlay in any way.

The articulated arm is in the ceiling area of the armored vehicle attached, resulting in a relatively large, vertical Extension length of the rope leads. This enables one Users, in turn, by transverse deflection of the rope too removed areas of the interior of the armored vehicle with to reach the holder attached to the rope.

The articulated arm preferably comprises one with its one End articulated to the end of the armored vehicle Arm link and one at the other end of the first arm link articulated second arm link. A bipartite Structure of the articulated arm has proven to be advantageous around the articulated arm in faster and more reliable Way in a desired position.

In a special embodiment of the invention, that the winch from a servo winch known per se is formed. The servo winch enables electrical Weight balance that it gives the user of the lifting device allows the grenade with relatively little effort record, relocate and at a desired location to discontinue.

Any holder can be used to hold the grenade Find a device that can be picked up quickly the grenade enables and their secure mounting guaranteed. It is preferably provided that the Holder has a receptacle in which to be lifted Grenade is insertable, and has a locking element, by means of which the grenade optionally in the intake can be determined or released from this. It can Locking element a slidably mounted, spring-loaded Deadbolt. Such a bullet gripper is out known from the applicant's patent application DE-A-44 42 313, the content of which is referred to.

When using the lifting device according to the invention a user will attach the holder to a possibly attached Grasp the handle. It has proven to be beneficial proven when on the holder also a control device arranged for the movement control of the winch is so that the user can raise and lower the grenade from the holder or even its handle can control. In an advantageous embodiment of the invention can be provided that the control device has an infrared sensor attached to the holder, the with a corresponding infrared receiver of the winch cooperates.

If the electric drive of the lifting device and thus the winch should fail, the in Armored vehicle operators the grenades reload manually. To make this easier, is in training the invention provided that the holder releasably is coupled to the rope. In the case of an electrical The holder can thus malfunction in the emergency operation of the rope removed and handled manually. The operator can keep the holder engaged with a grenade bring and over the handle attached to the holder handle and record. With manual operation it is due to the relatively high weight of a grenade useful and helpful if two operators use the Grenade grasp. For this purpose the holder another handle for the second operator exhibit.

So that the further handle in the normal operation of the Lifting device does not interfere and takes up too much installation space, is provided in a further development of the invention, that the further handle from a recessed in the holder Extendable or foldable position.

The lifting device cannot only be used to to take a grenade from the magazine and in one Put piecing, but by means of the lifting device the grenades can also be stored in the magazine become. For this purpose, the grenades from the Conveyed the outside of the armored vehicle in its interior are so that they are gripped by the lifting device and can be stored in the magazine. To the relative heavy grenades in a simple manner in the armored vehicle To be able to convey is a conveyor device according to the invention provided by means of which the grenade of the outside of the tank in the swivel range of the Articulated arm can be brought. The grenade is made by one Operator on the outside of the armored vehicle the conveyor is placed and can then in the Interior of the armored vehicle can be retracted.

An armored vehicle usually has on it Rear of a rear entrance hatch through a Hatch door is lockable and by the staff and / or material get into the interior of the armored vehicle can. In a particularly advantageous embodiment of the Invention is provided that the conveyor device at the entrance hatch, driven Sledge has. After the grenade on the When the sled is set down, the sled gets into the interior move so that the lifting device the grenade can take off directly from the sled.

So that the entrance hatch through the conveyor is blocked as little as possible, it can be provided that the slide can be pivoted together with its guide the door of the entrance hatch is attached and in the Entry hatch essentially releasing rest position can be brought. If the conveyor is thus is not required, it is pivoted into the rest position, in which they are as close as possible to the inside the door abuts so that the effective cross section of the Entry hatch is only slightly reduced. At Use of the conveyor will put it in its operating position folded down.

The lifting device is arranged and designed so that the articulated arm covers all essential areas of the interior of the armored vehicle. That way a projectile or a grenade from both for loading of the armored vehicle used sled, from the magazine, from any point on the bottom of the armored vehicle and from a commonly available tower magazine be included. The one picked up with the holder Grenade can be found in any of these locations as well in the piecer or directly in the weapon be filed.
