Description

The invention relates to a vehicle for transporting people with a transport surface for positioning of persons to be transported and / or objects and with at least one closable opening, which allows access to the transport surface of the vehicle outside in the open state. In particular, the invention relates to a vehicle according to the preamble of claim 1, wherein further in the direction of vehicle outside extendable in a travel direction functional element is provided in at least one far extended from the vehicle first functional position is pivoted downwards so that the functional element as on the ground upstanding ramp for loading and unloading the transport surface is available. Such vehicles are known from the practice, in particular in the form of ambulances (KTW) and ambulances (RTW) and in the form of other passenger vehicles. The ramp mentioned above is used in such vehicles, for example, for loading and unloading mounted on rollers chassis, e.g. for loading and unloading wheelchairs and / or wheelchairs.

The invention has for its object to improve the variability and thus the utility of such a vehicle.

To solve the problem is provided in a vehicle according to the preamble of claim 1, that at least one cooperating with the functional element fixing means is provided to fix the transport surface in a far less extended from the vehicle second functional position such that they for manual settling or Placing of transportable persons or objects can be used as a pedestal. This makes it possible to additionally use a ramp provided in the vehicles mentioned at the outset, which is actually used for loading and unloading chassis mounted on rollers, in addition as a pedestal. Such use is particularly considered when due to confined space conditions, a complete extension of the ramp and the pivoting required for use in the first functional position down to the ground is not possible. In this case, the ramp can be pulled out only partially, for example by 60 cm, 80cm or 100cm, as an extension of the transport surface to create a well-accessible for auxiliaries pedestal on which a wheelchair or other chassis can be pushed to this comfortable from the pedestal to the ground to lift or vice versa from the ground on the pedestal up. It is advantageous in this context, in particular, that the pedestal of two or more operators is much more accessible than the transport surface, which is located entirely within the vehicle. Accordingly, it is not necessary for an operator to get in or out of the vehicle to load or unload a person, thus having to overcome a mostly relatively high step between the transport surface and the ground.

In particular, known locking means, such as detent balls, spring-loaded bolts or other suitable fixing means, in particular mechanical fixing means, come into consideration as fixing means in the sense of the invention.

In a practical embodiment of a vehicle according to the invention, a latching mechanism, a clamping mechanism and / or a bolt safety device are provided as fixing means. In addition to the above embodiments, reference is made, in particular, to spring-loaded detent balls which, with one or more openings, block the functional element in one or more predetermined second functional positions. The release of such a spring-loaded detent ball can be achieved, in particular, by a sufficiently large release force (for example a footstep) acting as a functional element used as a pedestal. Alternatively or in addition, reference is made to locking means which must be manually operated in order to use the ramp of a vehicle according to the invention in its second functional position as a pedestal can. Such a manual operation is to be preferred in particular when the use in the second functional position is rarely considered. This has the advantage that during normal pulling in and out of a ramp to use the first functional position no automatic blocking takes place, so that the standard function (first functional position) is not affected by the second functional position in normal operation.

1. a) das Funktionselement in einer eingefahrenen Transportstellung zumindest überwiegend in einem Bereich unterhalb der Transportfläche verstaut oder
2. b) befindet sich das Funktionselement in einer eingefahrenen Transportstellung auf dem gleichen Höhenniveau wie die Transportfläche und bildet somit einen Teil der Transportfläche.

In a further practical embodiment of a vehicle according to the invention

1. a) the functional element stowed in a retracted transport position, at least predominantly in an area below the transport surface or
2. b) is the functional element in a retracted transport position at the same height level as the transport surface and thus forms part of the transport surface.

According to variant a), for example, a double floor is provided, wherein the space provided between the two floors cavity serves as a storage space for the ramp when it is not used, that is, in particular while driving with a vehicle according to the invention. Of the The above-mentioned cavity can thus be considered as a receiving space for the functional element.

According to variant b) it is provided that a part of the transport surface or the entire transport surface itself can be used as a functional element. In this case, the transport surface itself is pulled out of the vehicle and can be pivoted when sufficiently far pulling out of the vehicle as a ramp down to the ground. Likewise, the transport surface can be used in a second functional position as a ramp.

In connection with the last-explained variant b), it is advantageous if a cover is provided which closes the area of the functional element adjoining the vehicle inner side end during extension of the functional element. This is to be understood in particular as meaning that on the inside of the vehicle, even during the complete or partial removal of the transport surface, a plane, preferably also a weight-bearing transport surface, is maintained. This can for example be realized by the vehicle inside where a retractable functional element ends, a kind of shutter element or an additional plate stowed in a subfloor is provided, the one or more when pulling out between the vehicle inside end of the functional element and the subsequent vehicle-fixed Area of the transport surface gap continuously closes.

In a further practical embodiment of a vehicle according to the invention, a stop element extending in the vertical direction of the vehicle and in a direction transverse to the direction of travel is arranged in the region of an end of the functional element oriented in the direction of the vehicle or it is a stop element extending transversely in the vehicle vertical direction and in one direction extends to the direction of travel provided, which is designed such that this stop element is connectable with an outwardly vehicle-oriented end of the functional element. With transverse to the direction of travel is to be understood in this context, in particular an orientation perpendicular to the direction of travel.

But there are other, different orientations possible. The provision of a corresponding stop element has the advantage that an end facing away from the vehicle can be secured by means of the stop element against "rolling over". In that regard, reference is made, in particular, to a stop edge that is outstanding in the vertical direction of the vehicle relative to the surface of the functional element as a stop element.

Preferably, the stop element is functionally connected to the functional element and movably arranged on this. This means, in particular, that the functional element can be movably arranged in such a way that a translational and / or rotational process of the functional element for use as required, in particular when the functional element is in the second functional position, is provided.

Alternatively or in addition thereto, an extension stop for the functional element can be provided on the functional element, the transport surface or another element of the vehicle, with which it is ensured that the functional element can only be pulled out of the vehicle up to a maximum extension length. Thus it can be safely avoided that an operator pulls the functional element to use the first functional position too far out of the vehicle and it comes before or during an intended use of the functional element as a ramp to a complete withdrawal of the functional element from the vehicle, whereby the vehicle-side End of the functional element could detach from the vehicle and fall to the ground. In particular, reference is made in this context to laterally outwardly projecting bolts, which serve as stop elements and allow reaching an end position pivoting of the functional element down in the direction of the bottom.

In a further practical embodiment of a vehicle according to the invention, the transport surface and the functional element are arranged at different height levels. This has the advantage that the functional element, in particular when it is used as a pedestal, can also be used to reduce the height level for raising or lowering a wheelchair or other mobile frame in the area of the pedestal. The functional element can be regarded as a kind of stage that facilitates the loading and unloading of persons and objects.

If the transport surface and the functional element located in the second functional position are arranged at different height levels and furthermore a ramp element is provided in order to produce a ramp-like transition between the different height levels, moving a mobile frame from the transport surface to the functional element is facilitated. In this case, there is a kind of mini-ramp to bridge the different height level.

In a further practical embodiment of a vehicle according to the invention, at least one drive element is provided by means of which the stop element and / or the ramp element can be driven. These include both active drive elements, such as motor drive elements to understand as well as passive drives, such as a cable drive, a spring-loaded and / or the gravity-exploiting drive. In particular, reference is made in this context to drives that bias themselves when retracting or folding down, so that the movement in the opposite direction, that is, the extension or folding up is supported by the induced bias. Thus, the operation for operators of a vehicle according to the invention can be facilitated.

Finally, it should be pointed out that the functional element preferably has a length of between 1.50 m and 5 m, with the functional element being extended a maximum of 1.20 m out of the vehicle in the second functional position.

The 1 to 7 show a first embodiment of a vehicle according to the invention 1 , The 8th to 10 show a second embodiment of a vehicle according to the invention 1 , wherein identical or at least functionally identical elements in all figures, the same reference numerals are used.

As in particular from a synopsis of 1 . 2 and 6 it can be seen, the vehicle points 1 a transport area 2 on, on which any transportable objects or people can be placed. An example of this is in the figures a wheelchair 4 shown.

Below the transport area 2 is a functional element 3 arranged in 1 is shown in the retracted state. In this state, the functional element 3 under the transport surface 2 arranged.

As in 6 shown, it is possible to use the functional element 3 extend far, which is done in the embodiment shown by manual extraction in the vehicle longitudinal direction to the rear to a stop element, not shown. The stop element may be, for example, laterally out of the functional element 3 outstanding bolts that come with a blocking surface in the region of the rear end of the transport surface to the plant. In this far extended first functional position, the functional element - as in 6 shown - swung down to the ground and used as an up and down ramp. This form of use, in the mobile racks, such as a wheelchair 4 , by simply pushing with little effort from the ground to the transport surface 2 pushed up or down from the transport surface to the ground is in 7 exemplified.

As in 2 shown, the functional element 3 alternatively brought into the shown in this figure, less far extended second functional position and fixed in this to the functional element 3 as a pedestal for manual loading and unloading Unloading objects and / or persons. For fixing the functional element 3 in this second functional position, a fixing means not shown in detail is provided, by means of which further relative movements of the functional element 3 opposite the transport surface 2 be prevented, in particular relative movements in the vehicle longitudinal direction. As such a fixing means, for example, a quick release and / or a combination of a detent ball or a plurality of detent balls and a corresponding recess or a plurality of corresponding recesses (not shown) are used. Alternatively, the ramp can be designed latchable with another, not shown, mechanics to this in the second functional position as a ramp relative to the vehicle 1 to fix.

As in the 2 and 3 can be seen results in the second functional state of the functional element 3 a height difference in the form of a step between the transport surface 2 and the top of the functional element 3 , To bridge this step by means of a suitable up and down ramp, is a ramp element 5 provided, which can be manually inserted. Alternatively, the ramp element 5 also on the transport surface, the functional element 3 or any other element of the vehicle 1 be arranged that before, during or after pulling in the vehicle longitudinal direction according to the in 2 shown arrow in the in the 2 and 3 shown used position is spent. Only by way of example in this regard is a in the functional element 3 and / or in the area of the transport surface 2 sunken ramp element 5 referenced, when reaching the second functional position automatically in the in 3 shown position is moved and is sunk in a further extension or re-retraction.

In 5 is well recognizable that the functional element 3 in the second functional position the accessibility of operators to different sides of a wheelchair 4 improved by two operators from different sides of the wheelchair can reach well to this from the ground on the functional element 2 to lift or from the functional element 2 to lift to the ground.

In the in the 8th to 10 illustrated, alternative embodiment is the transport surface 2 in the retracted state of the functional element 3 partly by a vehicle-mounted floor area 10 , one as a functional element 3 serving back plate 8th and formed in the vehicle longitudinal direction before further sliding plate.

The as a functional element 3 Serving plate is thus part of the transport area 2 , She will be in the in 10 shown first functional position - analogous to 6 and 7 - used as a ramp and can alternatively in the in 9 shown second functional position - analogous to the 2 . 3 and 5 - be used as a pedestal.

For the sake of completeness, it is still pointed out that at the rear end of the functional element 3 in the second functional position - independently of the realized embodiment optionally serving as a stop element flap 6 is provided. In the embodiments shown, this flap can be 6 pivot as needed in the recognizable in the figures, folded in the vehicle vertical direction upwards position to avoid that a mobile frame, the out of the vehicle 1 on a serving as a ramp functional element 3 is driven, is rolled too far out and then can fall off the ramp.

The first functional position of the functional element 3 is usually used when there is enough space. In this case, the flap 6 - as in 6 recognizable - be folded down. As in 7 can then be shown in a wheelchair 4 seated person in the vehicle 1 pushed in or pushed out of these.

The pivot point of the functional element 3 opposite the transport surface 2 In the embodiments shown, each one is selected such that the vehicle-side end of the functional element serving as a ramp 3 approximately flush with the surface of the transport surface 2 concludes. The use of the ramp element 5 or a similar element is therefore not required in this case.

As in the 9 and 10 it can be seen, the transport surface 2 in the second embodiment, in the case where the functional element is at least partially out of the vehicle 1 pulled out, through a shutter element 9 formed, which keeps a transport-side opening closed by it like a jalous with the vehicle front end of the front plate 7 with moves. This is the shutter element 9 in the embodiment shown fixed to the front plate 7 connected.

The features of the invention disclosed in the present description, in the drawings and in the claims may be essential both individually and in any desired combinations for the realization of the invention in its various embodiments. The invention is not limited to the described embodiments. It can be varied within the scope of the claims and taking into account the knowledge of the person skilled in the art.
