Description

The invention relates to a deployment ramp for storming objects that are higher than a base area. The ramp has a web, which is connected to a foot part for support on the base surface and a head part for fixing to the higher object at opposite ends. Between the foot part and the head part there is a walking surface on which people can walk in a usage position of the web and the foot and head parts in a walking direction extending in the longitudinal direction of the web from the base surface to an entry opening of the object.

In the field of police work, it is known that emergency services, in particular special task forces, have to quickly penetrate an object, for example an apartment, a bus or a train, in certain situations. Here, differences in height often have to be overcome, whereby it is important that the emergency services get to the corresponding object quickly and safely.

The emergency services usually use ladders in order to be able to get to correspondingly higher objects and to storm them. In many cases, the emergency services have to penetrate the object to be stormed via canopies, balcony railings or through window panes. It is of particular importance here that the penetration aids can be fastened reliably and quickly to the object to be stormed, so that the emergency services can get into an object with as little loss of time as possible.

In addition, special emergency vehicles such as the Ford F-550 developed for the police are known, which have movable ramps as a structure, but can only be used to storm comparatively easily accessible objects.

The problem with the boarding aids known from the prior art is often that they can only be used with difficulty in rough terrain, the structure is comparatively complex, they are difficult to transport, no level running surfaces are provided or the fixation in the area of the storming of the object is only insufficient.

CN 202 039 763 U discloses an emergency ramp according to the preamble of claim 1. Based on the technical solutions known from the prior art and the problems described above, the invention is based on the object of further developing an emergency ramp for emergency services, in particular police emergency services, for storming objects This means that they can be transported comparatively easily and both rapid construction and secure attachment to the object to be stormed is ensured. Furthermore, it is important that an appropriate deployment ramp is easy to carry and handle by the emergency services, even in rough terrain. Furthermore, it should be possible to overcome different height differences, for example from the ground to higher floors, or in a bus or a train, in a simple manner, with the emergency services and their equipment having to reach the object to be stormed safely via an appropriate tread.

The aforementioned object is achieved with a deployment ramp according to claim 1. Advantageous embodiments of the invention are the subject matter of the dependent claims and are explained in more detail in the following description with partial reference to the figures.

The invention relates to a deployment ramp for storming objects that are higher than a base surface, with at least one web, to which a foot part for support on the base surface and a head part for fixing to the higher-lying object are connected at opposite ends. Between the foot part and the head part there is a walking surface on which people can walk in a usage position of the web and the foot and head part in a direction extending in the longitudinal direction of the web from the base surface to an entry opening of the object. The solution according to the invention is characterized in that the head part has at least one unit for breaking or pressing in glass and a hook element which, in the position of use, in which the foot part is supported on the base surface and the head part is fixed to the object, is a component of the Object at least partially encompasses, has. The unit for breaking or pressing in glass or the so-called glass breaker and the hook element are preferably integrated in a fixing element of the head part. What is essential about the invention is that a deployment ramp is provided for the application, which on the one hand provides a safe walking surface and on the other hand ensures both rapid opening of an entry into the object and reliable attachment to the object.

According to the invention, the head part is designed in such a way that the web with the running surface can be fixed to the object in at least two positions in which the running direction is oriented differently from the object. It is essential here that the head part is designed in such a way that on the one hand a reliable fixation on the object, for example on a railing or a window frame, is ensured and on the other hand the ramp can be oriented differently relative to the object. This is particularly important for operations in which the emergency services should not be seen for as long as possible and therefore approach the opening provided for entry parallel to the outer wall of the object to be stormed.

In this context, it is conceivable that the head part of the ramp is designed in such a way that emergency services approach an object and in particular an access opening located in the outer wall of the object both parallel to an outer wall or outer surface of the object and perpendicularly, i.e. quasi frontally . In a preferred manner, the head part therefore has a suitable element that enables the deployment ramp to be securely fixed in different positions relative to the object provided for storming or the corresponding access opening provided for this purpose. Basically, it is conceivable in this context that the head part has exchangeable fixing elements or that fixing elements are provided on the head part that are designed to be foldable, rotating or pivoting, so that the head part with the ramp on it can be fixed in different positions on the object. It is advantageous here if the head part with its fixing elements is designed in such a way that the ramp moves independently into a fixed position after the hook elements have been hooked in and remains in this position even under load. Support elements in the form of support plates and/or stop elements, for example made of rubber, are preferably provided in the area of the head part, which support the ramp in its operating position on the object, in particular an outer wall of the object, and in this way fix it. It is important here that the hook elements remain in the desired position when the object is stormed. This is achieved in an advantageous manner by rubberized stop elements in the area of the head part, which hold the head part in position without any load and allow the position to be changed to a stable or fixed end position when the suspended ramp is lowered.

In a very special embodiment of the invention, it is provided that the head part is designed in such a way and the web with the running surface can be positioned in such a way that there is an angle of 90° between the running direction in a first orientation relative to the object and the running direction in a second orientation relative to the object °, particularly preferably enclosed by 180 °. With a ramp designed in this way, it is possible to approach the entrance opening of the object either frontally from the front or else from the left or right of the entrance opening parallel to the object.

Furthermore, it is conceivable in an advantageous manner that a length of the running surface of the ramp is variable in the running direction. This means that the length of the deployment ramp can be varied as required, so that different heights between the base area, for example the ground and a higher object or the entry opening of a higher object intended for storming, can be overcome. It is essential here that even when larger height differences are overcome between the base area and the entry opening of the object to be stormed the incline to be overcome by the emergency services does not exceed an impermissible value so that they can get into the object with their equipment as quickly and safely as possible.

In order to be able to vary the length of the running surface of the deployment ramp, different embodiments of the invention are available. For example, it is conceivable that a deployment ramp designed according to the invention is plugged together from at least two web parts, each with a partial running surface. It is also conceivable that the at least two web parts are connected to one another via a joint so that they can be pivoted or folded from at least a first into a second position in order to vary the length of the running surface of the deployment ramp. Furthermore, one embodiment provides that at least two web parts are arranged in such a way that they can be displaced relative to one another with the aid of a guide and are finally locked in the position of use. In this context, it is conceivable that the two web parts are shifted relative to one another and locked in different positions in such a way that insert ramps with different running surface lengths can be provided with the aid of two web parts.

In a particular embodiment of the invention, the at least two web parts of a deployment ramp can be plugged into one another. It is also conceivable that the head part, the foot part and/or other add-on parts are connected to one another by plugging. In a particularly advantageous manner, the two web parts are connected via an adapter that can be attached to at least one of the web parts without tools and can also be detached from this web part again without tools, with the parts plugged into each other being reliably locked in a position of use.

The essential idea is that a deployment ramp can be lengthened with the aid of a correspondingly designed adapter and at least one further web part, with the adapter having to be able to be attached as simply as possible to a web part provided for this purpose. It must always be taken into account that the deployment ramp should be set up by the emergency services on site as quickly as possible, with just a few movements and ideally without tools.

In a special development, the adapter unit has a rotating, pivoting or folding joint for connecting at least two web parts of a web, so that after the adapter has been attached, the at least two web parts can be brought into the use position by a corresponding movement. For example, it is conceivable that in the immediate vicinity of a vehicle intended for transporting the deployment ramp, the appropriate number of web parts are first pre-assembled using suitable adapters, then brought to the place of use and there the running surface of the web is brought to its final length, for example by folding at least one of the web parts.

Regardless of how the other components of a deployment ramp designed according to the invention are designed, it is always important that both a glass breaker and a hook element for fixing the ramp to a component of the object to be stormed are provided in the area of the head part. In this way, it is possible during an operation to quickly provide an entry opening in the object for the storm as well as to bring the operation ramp into the required position and to fix it in this position. The destruction of a window pane and the fixing of the deployment ramp to the object, in particular to the window frame of the destroyed window, preferably take place in one movement. A fixing element therefore preferably has, on the one hand, a hook element with a latching structure arranged on the inside of the hook and, on the other hand, an element for breaking glass on the outside of the hook.

According to a special development of the invention, a fixing element is provided on the head part, which is designed to be rotatable or pivotable and can preferably be locked in different positions relative to the running surface. It is also conceivable to provide a support element in the area of the head part, which enables the deployment ramp to be supported on the object in the area of the head part. Such a support element preferably has a support plate on which a threaded rod is fastened, so that the support plate can preferably be pulled out and locked in various positions along the threaded rod. In general, it is also conceivable that the support plate d is moved along the threaded rod, which takes longer than the previously described variant when used. With the aid of the movement mechanisms described above, it is thus possible in each case to move the plate in the direction of the object or away from it, so that reliable support of the ramp on the object can be ensured.

Furthermore, the deployment ramp designed according to the invention advantageously has a support element in the area of the foot part, which enables the web connected thereto to be securely fixed on the base surface, in particular on the ground. It is also advantageous if the support element has a unit that enables leveling.

The support element preferably has at least one base that can be locked in different positions, so that the deployment ramp can be securely fixed on the base surface at different angles of attack, uneven surface conditions and/or terrain inclines.

According to a further preferred embodiment, an element for fastening at least one wheel is provided in the area of the foot part. The provision of a wheel, which is at least temporarily attached to the foot part, offers the advantage that a ramp or at least one web connected to the foot part can be pulled or pushed to the place of use comparatively easily. The wheel element is preferably constructed in such a way that under load it yields to such an extent that the ramp has contact with the floor and further rolling is not possible. This can be implemented with a magnet that allows the wheels to fold away under a certain load, or with spring-loaded ladder rollers. Due to this technical solution, the ramp can be rolled out and brought to the object by one person. As soon as the first responder enters the ramp, the wheels can no longer roll and the ramp is fixed to the ground.

In addition, a deployment ramp designed according to the invention can have additional components that simplify the handling and use of the ramp for the deployment personnel. In this context, it is conceivable, for example, for carrying handles to be provided in the area of the webs, which can preferably be pulled out or folded out of the web area for use. It is conceivable here that the carrying handles are at least temporarily sunk into the side areas of a ridge and/or below the tread and are only pulled out for use.

Furthermore, according to its specific development, it is conceivable that in a deployment ramp designed according to the invention, in particular in the area of the running surface, lighting means are provided which identify or illuminate the running surface, in particular clearly emphasizing the lateral boundaries of the running surface. A deployment ramp designed in this way can therefore be handled easily even in poor visibility and in the dark. Furthermore, it is conceivable that at least a fastening element is provided for accommodating a support frame, which makes it possible to carry the deployment ramp or to place the deployment ramp in an elevated area. By providing such fastening elements, it is possible to attach such a carrying frame to a deployment ramp as required. A particularly suitable carrying frame can be attached to the bridge in such a way that the carrying frame can be folded out downwards and the deployment ramp can be carried at an elevated level and the deployment ramp can be placed on an elevated object, for example on the railing of a balcony or on an elevated window sill or window frame, is possible.

figure 1 shows the basic structure of a deployment ramp 1 designed according to the invention, which can be assembled from a number of different components. Preference is given to the individual in figure 1 illustrated components of the deployment ramp 1 assembled by plugging together, the individual connectors are designed such that a solution of the individual connectors only after prior release of a lock is possible. In this way it is ensured that the deployment ramp 1 is fixed to an object in the assembled state and can be walked on by the deployment forces.

In the figure 1 The deployment ramp 1 shown can be used in particular by special police forces to storm objects such as apartments, trains, coaches or local buses. When objects are stormed in this way, panes are often destroyed with the help of glass breakers, so that an entrance opening into the object is created. This in figure 1 The head part 3 shown has two fixing elements 8 which have a hook-shaped holding element 7 and a glass breaker 6 . During an operation and the storming of an object with the ramp 1 shown, a window pane is first destroyed with the glass breaker 6 provided on the outside of the hook-shaped holding element 7 and the holding elements 7 are suspended in the window frame. This is a process in which the hook element is hooked in and a window closing the entrance opening is destroyed at least almost simultaneously.

Likewise, the foot part 3 is designed to be adjustable in height, so that the deployment ramp 1 can be securely locked on a floor or on the ground. It should be expressly pointed out that the in figure 1 The deployment ramp 1 shown in the disassembled state is suitable for storming different objects over balconies, canopies or through windows. It is essential here that the hook elements 7 provided on the head part 4 of the deployment ramp 1 have a suitable latching structure 11 which can be attached to a corresponding counter-element around which the hook 7 grips at least in certain areas, such as a railing, a roof overhang, a window sill or a window frame. can be attached.

The locking structure 11 provided in the hook-shaped holding element 7 ensures that the holding elements 7 for fixing and the ramp 1 connected thereto via the head part 4 are reliably prevented from slipping off.

The essential components of the figure 1 The deployment ramp 1 shown in the disassembled state is the two web parts 2a, 2b with the running surface 5 arranged thereon, an adapter element 9, via which the two web parts 2a, 2b can be connected to one another, the foot part 3, which rests on a base surface from which the Storming of a higher object is made, can be parked and has a headboard 4 for supporting and fixing the ramp 1 on the higher object to be stormed. In a preferred manner, the individual components of the deployment ramp1 shown are brought to the vicinity of the deployment site in a disassembled state. Immediately before use, the different components are plugged together and brought to the site of use, preferably in an already assembled state. In order to be able to transport the deployment ramp 1 in a simple manner and to bring it from the place of assembly to the place of use, handles 15 are provided on the side of the two web parts 2a, 2b, which handles can be pulled out of the web 2 for use and can be grasped in this way. In addition, wheels 13 are arranged in the area of the foot part 3, so that the deployment ramp can be pulled or pushed to the deployment site, provided this is permitted by the deployment site. The wheels 13 are, as in figure 5 shown, designed in such a way that they fold down under load and the foot part 3 then rests securely on the base surface.

Furthermore, a special adapter unit 9 for connecting the two web parts 2a, 2b can be seen, which has at least one joint 10 so that the two web parts 2a, 2b of the deployment ramp 1 can be folded together. It is therefore conceivable to first plug a corresponding ramp 1 together at an assembly site, then to fold the two web parts 2a, 2b together so that the length of the deployment ramp 1 is roughly halved and the ramp 1 only unfolded directly at the deployment site and in position for storming an object bring to.

The individual components of the deployment ramp 1, namely the base 3 and the head part 4, the adapter unit 9 and the at least two web parts 2a, 2b used are made of aluminum or steel and are anodised, painted, coated and/or at least in sections with provided with a foil.

In figure 2 a single web part 2a, 2b, which can also be referred to as a web element, is shown, as is used for a deployment ramp 1 designed according to the invention. The web element 2a, 2b can be assembled with the head 4 and foot parts 3 to form a deployment ramp 1, or it can also be assembled with other web elements 2a, 2b, preferably by using special adapters 9. The web element 2a, 2b has profile receptacles 16 at the opposite ends in the running direction, into which plug-in profiles 17 of suitable add-on parts can be inserted, with automatic locking taking place as soon as the plug-in profile 17 is in the intended position within the receptacle 16. The receptacles 16 provided at the opposite ends in the direction of travel are advantageously designed in a standardized manner such that a head 4, a foot 3 or an adapter part 9 can be fastened to the respective end. This offers the great advantage that, when assembling a ramp 1, the emergency personnel do not have to pay attention to which of the components has to be fastened to a corresponding end. The construction of the ramp 1 from various components, in particular the plugging together of the head 4 and foot part 3 and/or at least one additional adapter 9 with a further web element 2a, 2b, is thus possible in a comparatively simple manner. It is also conceivable to attach rollers 13 at least on one side of the web part 2a, 2b either directly to the web element 2a, 2b or to a foot part 3 in order to make it particularly easy to transport a web part 2a, 2b, possibly with the other components attached to it , to guarantee.

In order to be able to offer the emergency services a running surface 5 that is as safe as possible, the surface of the web part 2a, 2b in the area of the running surface 5 is at least partially coated, rubberized or provided with special anti-slip elements such as knobs, grooves or other structures 19. In this way, it is ensured that the emergency services are reliably prevented from slipping if the running surface 5 is wet. In addition, there is a side area of the web part 2a, 2b, a retractable handle 15 which can be pulled out of the web element 2a, 2b, in particular from a recessed grip and/or openings provided for this purpose, and gripped if necessary. In addition, embedded handles 15 are provided both at the front and at the rear end of the bar element 2a, 2b, which can also be gripped if necessary to move the bar element 2a, 2b or to bring it to the required location.

As an alternative to the pull-out handles embedded on the side of the bar element 2a, 2b, it is conceivable to provide loops or similar holding elements that can be grasped as required to carry the bar element 2a, 2b from one location to another. It is also conceivable to provide receptacles for a support frame 14 on a web element 2a, 2b on the side and or below the web part, which is designed in such a way that the web element 2a, 2b or the deployment ramp 1 produced with the web element 2a, 2b, for example in a can be carried in an elevated position and/or placed in an elevated position relative to the ground. This may be necessary, for example, if the deployment ramp 1 is to be fixed to a balcony railing or if an apartment, a coach, a local bus or a train is to be stormed at a higher level.

Incidentally, the in figure 2 web element 2a, 2b shown via light sources, the use of LED light sources being particularly advantageous. With the help of such lamps, it is possible to mark the running surface 5 and in particular the lateral boundary of the running surface 5 in the dark or when visibility is poor. Furthermore, it is conceivable to provide at least one radiator, in particular in the front area of the web element 2a, 2b, which makes it possible to illuminate the area below or in front of the ramp 1.

In figure 3 an adapter element 9 is shown, via which two web elements 2a, 2b of an application ramp 1 designed according to the invention can be connected. The adapter element 9 has suitable profiles 17 for connecting two web elements 2a, 2b, which are inserted into the receptacles 16 provided for this purpose in the web elements 2a, 2b, with the adapter element 9 being automatically locked within the receptacles 16. This in figure 3 The adapter element shown also has a folding hinge 10, so that two web elements 2a, 2b, which are connected to form a web 2 with the aid of the adapter element 9, can be folded over one another, for example in order to facilitate the transport of the web 2 and/or the already assembled deployment ramp 1 .

By providing a correspondingly foldable or articulated connection between two web elements 2a, 2b, the transport of a mounted ramp 1 is made easier on the one hand and the operational readiness of a task force is accelerated on the other hand. To prepare for use, the adapter element 9 is opened with the plug-in profiles 17 attached on both sides, so that a uniform running surface 5 of the web elements 2a, 2b connected to the adapter element 9 is produced in the running direction of the use ramp. In this case, the joint 10 or hinge of the adapter element 9 is automatically locked with the aid of a latching element 20 in order to prevent the adapter element from being opened unintentionally. In this context, it is conceivable to provide a latching element 20 designed as a snap lock or similar connecting element, which, on the one hand, enables quick and reliable locking of the joint 10 or hinge and, on the other hand, enables comparatively easy subsequent opening.

figure 4 shows a foot part 3 for a deployment ramp 1 designed according to the invention. Such a foot part 3 can in principle be an integral part of a web element 2a, 2b with running surface 5 of a deployment ramp 1 or as a separate component which, if necessary, can be connected to a web 2 or web element 2a, 2b Plugging is connected to be executed. Essential to the in figure 4 On the one hand, the foot part 3 shown is that a holding part 15 is provided, via which the foot part 3 and the ramp 1 connected thereto can be carried. On the other hand, a stand 23 is provided with which the foot part 3 can be placed on a floor surface and securely fixed on it. In this context, it is conceivable to provide feet 23 that have a structured surface in order to reliably prevent an unintentional shifting of the foot part 3 on the floor surface.

In addition, the foot part 3 has an element 18 for leveling. With the help of such an element 18 for leveling, the foot part 3 can be locked at different heights relative to the floor surface and the foot part 3 can thus be optimally adjusted in relation to the ground. In this way, twisting of the ramp 1 and the associated instability are reliably prevented. It is also conceivable to use the element 12 of the holder 15 protruding laterally to attach a wheel 13, so that the foot part 3 with the attached web 2, web element 2a, 2b or the entire ramp 1 can be pushed or pulled between an assembly location and to transport it to a place of use.

In figure 6 a head part 4 is shown that is attached to a web 2 or web element 2a, 2b of a deployment ramp 1. In the upper area, the head part 4 has two parallel fixing elements 8, which have a unit 6 for breaking glass and a hook element 7, which at least partially encompasses a component of the object, such as a roof overhang or a window frame, during use. On the inside, the hook element 7 has a latching structure 11 with gripping teeth, via which the head part 4 with the deployment ramp 1 attached thereto is reliably fixed to the object to be stormed. Also arranged on the side of the hook element 7 opposite the locking structure 11 are so-called glass breakers 6, which are used to destroy a pane of glass when an object is stormed.

When an object is stormed, in particular an object that is higher than a base area, the emergency services first position the ramp 1 in front of a possible entry opening, in particular in front of a window, and destroy it with the help of the glass breakers 6 the glass pane and hang the fixing elements 8 with the locking structure 11 of the hook elements 7 in the window frame, so that the emergency services can reach the object intended for storming comparatively quickly via the running surface 5 of the web 1 . In order to achieve a stiffening of the head part 4, bracing wires or struts are also provided, which run from an upper part of the fixing elements 8 to a side area of the web element 2a, 2b connected to the head part 4. Furthermore, 4 support elements 21 are provided in the lower area of the head part, which have a threaded rod with a support plate. By moving the support plate along the threaded rod and locking it in the desired position, it is brought into contact with the outer wall of the object being destroyed in such a way that reliable support and fixation of the deployment ramp 1 on the object is ensured and unwanted movements of the ramp are avoided.

This in figure 6 The head part 4 shown with its fixing elements 8 is constructed in such a way that the deployment ramp 1 is fixed to the object in a frontal direction in order to be stormed. The fixing elements 8 with the glass breakers 6 each having a striking arm and the hook elements 7 with a locking structure 11 are rotatably arranged in a receptacle serving as a guide 22 and in the in figure 6 locked in the position shown. The locking can be released by light pressure against a spring element and the fixing element 8 can then be rotated into another desired position and locked there. It is also conceivable to implement locking with the aid of cotter-locked bolts.

In addition, the fixing elements 8 are protected against being completely pulled out of the guide receptacle 22 by a suitable blocking element.

In figure 7 is again a head part 4, which is attached to a web element 2a, 2b of a deployment ramp 1, is shown. The components used are the same as in figure 6 shown, which were only converted for the other purpose, namely an approach parallel to the object.

In the figure 7 In the operating position shown, the fixing elements 8 with their hook elements 7 and the glass breaker 6 in the guide receptacle 22 are rotated by 90° compared to the operating position shown in FIG. Furthermore, this is in figure 7 head part 4 shown has been designed with a supporting element 21, which extends beyond the web 2 and slightly at the side. With the help of a deployment ramp 1, the head part 4 of which is as in figure 7 shown, is set, a deployment ramp 1 can be arranged parallel to an object to be stormed. This makes sense in particular when the emergency services want to approach an entry opening parallel to the object to be stormed because there is no other way for reasons of space or in order to be recognized as late as possible. In this case, too, the fixing element 8 in turn has an element 6 for breaking glass, the In this case, pressure on the pane is not exerted by an impact, but by tilting the ramp 1 to the side. On the opposite side there is again a hook element 7 with a latching structure 11 in order to ensure that the deployment ramp 1 is suitably fixed to the object to be stormed. Furthermore, 8 steel cables or struts are provided on the fixing element, which allow diagonal bracing for further stiffening of the head part 4 . As already explained, the support element 21 is adjusted in this case in such a way that it protrudes laterally beyond the head part 4 and enables the ramp 1 to be laterally supported on the object here in the lower area. In order to use a fixing element 8 with the hook element 7 and the glass breaker 6 designed as a striking arm from the figure 6 shown in the in figure 7 To transfer the position shown, it is first pressed down against spring pressure, rotated by 90° and then released again, so that the desired locking then takes place automatically. suitable guide lugs are provided for locking, which engage in the required position in corresponding receptacles. It is also conceivable to provide a technical solution in which the fixing elements 8 are removed from the guide 22, rotated and locked with the aid of a cotter pin.

figure 8 shows a head part 4, which is preferably used for storming objects whose entry opening is closed by a laminated glass pane. Here, the composite property of the pane is used, which does not disintegrate but is pushed or pressed as a whole into the interior of the object.

the Figures 8a) to 8c ) schematically show the attachment of the ramp 1 to the object in consecutive order. After the laminated glass pane has been pressed in, the ramp 1 rests on the frame, is pulled back and the hook element 7 hooks into the window frame, as shown in Figure 8b ) is shown. Ramp 1 is then pulled out completely and inevitably falls into the end position, which is Figure 8c ) is shown.

A head part 4 is in turn attached to the web element 2a, 2b of the deployment ramp 1, which has fixing elements 8 which, together with the glass breaker 6, on the one hand serve to press in the pane and on the other hand have a hook 7 with guide lugs or a suitable latching structure 11. The fixing elements 8 can be reliably attached to a railing, a roof overhang, a window sill or a window frame via the latching structure 11 . The essential feature of the in figure 8 illustrated head part 4 is that the fixing elements 8 can be pulled or moved into the required position.

As in Figure 8a and 8b shown, it is conceivable that during the fixation of the deployment ramp 1 on the object to be stormed, the fixing elements are hung, for example, on a window frame and then the deployment ramp is pulled back into the desired deployment position. If an object is stormed, the fixing elements 8 with their hook elements 7 are in the pushed-in position, so that they lie firmly against the base body when they hit a window surface. After a window has been pushed in, the hook element 7 hangs with the latching structure 11 in the window frame of the destroyed window and the deployment ramp 1 is pulled back.

When pulled out, the fixing elements 8 are pulled forward out of the ramp 1, reach a stop and the ramp 1 is in the desired position after it has moved slightly downwards, at least in the front area. In this position, the ramp 1 is again supported on the object. Stiffening of the head part 4 is achieved with the aid of struts or wire ropes. In this case, the transverse reinforcement makes sense in order to achieve the largest possible impact area and stability.

figure 9 shows a special embodiment of an application ramp designed according to the invention, which can be used as a ladder with rungs 25 or as a ramp 1 with a running surface 5, depending on the application. the inside Figure 9a The main body shown is composed of four sub-elements, with suitable fastening elements being provided in order to connect the individual parts to one another quickly and securely. It is also conceivable to provide a corresponding body, the modules according to figure 9 four modules, are designed to be foldable or foldable relative to one another. Rungs 25 are provided between the individual webs 2 of the ramp base body, which ensure easy and safe access to the ramp 1, especially if the ramp 1 is placed or leaned against a wall or a vertical obstacle, for example, or the individual modules are plugged together or are folded that an obstacle, such as a fence, can be overcome with the help of the ramp.

Furthermore, two flat struts are provided which are displaceably arranged as stiffening elements 26 for stiffening the running surface 5 and which can be shifted between a position in which they bear against the lateral struts 2 into a central position. With the help of these stiffening elements 26 designed as flat struts, which have bores through which the rungs 25 run in this area, a stiffening is realized for applications in which the basic body shown is intended to provide a running surface 5 for a deployment ramp designed according to the invention. In this context shows Figure 9a the base body with stiffening elements 26 designed as flat struts, which bear against the lateral struts 2, so that the base body can be used as a ladder. here it is fundamentally conceivable that the individual modules of the base body can be plugged together, pulled apart, folded relative to one another and/or foldable relative to one another. In Figure 9b are the provided as stiffening elements 26 flat struts in their shifted to the middle of the rungs 25 position. Arrests are preferably provided for this purpose on the rungs 15, which prevent or at least make it more difficult for the stiffening elements 26 to be unintentionally displaced from the central position into the lateral position.

Figure 9c shows the basic body made up of four modules that have been put together or consist of four modules that have been folded apart, with a running surface 5 attached to it. Advantageously, the running surface 5 is designed in the form of plates or as a roll-up grid, which is applied on one side to the rungs 25 reinforced with flat struts 26 becomes. It is conceivable that the running surface 5 is permanently attached to the rungs or the individual modules of the base body, is adaptable in its length and/or width and/or, if necessary, on the base body, e.g. by pulling or sliding one of many Rod elements existing tread 5 is attached.

In Figure 9d shows the use of the modular base body shown in connection with the illustrations 9a to 9c for an application ramp designed according to the invention. Depending on requirements, a head part 3 and/or a foot part 4 can in turn be attached to the base body, which can be used either as a ladder or as a ramp or work platform. The foot part preferably has height-adjustable foot elements 23 that can be adapted to the existing height profile of the ground at the place of use. The head part 3 with the hook element 7 and the glass breaker 6 in turn enables the deployment ramp to be fastened, for example, to a window frame or a balcony railing. In addition, holding elements 15 are provided, which allow comparatively simple handling and carrying of the modular deployment ramp 1 at the deployment site.

In the figure 9 The deployment ramp shown is particularly versatile because it can be used as a ladder or as an deployment ramp or work platform. In this context, it is also conceivable that the individual modules can be plugged together with or without a separate adapter 9 in such a way that the outer modules are set up on the ground and the middle modules serve as a level platform. It is also conceivable to put them together or fold them in such a way that the ramp 1 or ladder can be used as a sort of bridge to overcome an obstacle, in particular a fence or a wall.

figure 10 shows a further special embodiment of a base body consisting of different modules for a deployment ramp according to the invention. Depending on the intended use and depending on the place of use, a different number of modules can be used for a deployment ramp. The desired number of modules is plugged together before use, preferably in the immediate vicinity of the place of use, with the individual modules advantageously being designed to be foldable relative to one another. Depending on requirements, suitable head 3 or foot parts 4, as have already been described in detail, can be connected to the base body.

According to the figure 10 In the illustrated embodiment, the running surface 5 is located on top of the modules of the base body, while a plurality of rungs 25 are arranged below the running surface. By simply rotating the base body, an at least partially closed running surface or a plurality of rungs can be provided, so that it can be used as a ramp 1 or as a ladder. In this context, it is conceivable that as soon as it is determined during an operation that the incline is too steep for walking over a ramp, a ladder can be made available comparatively quickly by simply rotating the base body.

Generally it is, particularly in relation to in the figures 9 and 10 shown body conceivable, the body with a head 3 and / or a foot 4 or can be used as a separate ladder or simple docking ramp. It is essential here that both a step-free running surface 5 and a ladder with rungs 25 can be made available with the illustrated, modular basic body.

With regard to the running surface 5 and/or the rungs 25, it is fundamentally advantageous if the respective surfaces are at least partially secured against slipping. This can be realized in particular with the help of a suitable surface coating, a so-called anti-slip coating and/or surface treatment with the same effect, such as roughening, rubber coating and/or the provision of special surface elements.
