The invention relates to a stretcher platform or a stretcher mounting device for the lockable Holder of different stretchers, especially in off-road vehicles, with U-shaped Guide rails whose rail width is at least suitable for the stretchers with the largest foot width is sufficient, at least one guide rail is widened so that both wear with the least as well as stretchers with the largest gauge can be inserted.

Such a hospital platform or Tragcnlagerungsvorrichlung is known from DE-AS! 0 68 426. This publication first explains: that the arrangement of guide rails of different widths for receiving stretchers of different Track width is disadvantageous because it can be adjusted the gauge is missing. Therefore, in this print

Scripture suggested that the track width of the guide rails by inserting additional guide elements in to change the guideway according to the gauges of the stretchers. Although it is mentioned that the additional Guide elements may be firmly attached to the stretcher of different widths in the Can be arranged in the longitudinal direction and in non-touched areas of the guide rails in the end position, however, it is not explained in more detail how this idea could actually be implemented constructively. Rather, based on the drawing, it is above all movable or adjustable by reverse assembly Guide elements described. As such, the crane carrying platform is used in particular around a transverse axis foldable rail ends, which in one of them Position the guide rails and extend the guide rails in their other position as stops shorten, where necessary with stretcher feet interacting stop or locking elements can be arranged. aside from that can be in the area of the end of the stretcher platform, which is used to place or slide the stretcher on Arranged around a vertical axis pivotable guide element be, which in its position parallel to the longitudinal axis of the stretcher platform reduces its track width and in its position, which is approximately parallel to the transverse axis of the stretcher platform, stretches can be put on with a larger track width, but hindered as the feet of the stretcher when touching down lifted over this guide element on the carrying platform or when removing it from the stretcher platform Need to become. How the stretchers are locked on this known stretcher platform is shown not shown.

DE-AS 10 95 461 only shows a stretcher platform with guide rails, on one of which a barrier protruding into the path of the stretcher with several, The holding pins are offset according to the different distances between the feet of different stretchers is arranged. This means that stretchers of different lengths can be carried on the stretcher platform, even if they are relatively unsafe be locked.

The object of the invention is to provide a universal stretcher platform or to create a universal stretcher storage device, which in a basic version for a larger number of types of wearers directly, i. H. without any adaptation measures to be carried out beforehand, is suitable and ensures a particularly effective locking

This object is achieved in that stretchers, the feet of which in addition to different foot widths and / or track width, if necessary, have different longitudinal distances to prevent impermissible relative movements can be locked in the direction of all three spatial axes secured by at one end of the rails the rail width narrowing stop pieces with wedge-shaped front inclined surfaces are firmly arranged, which block the end of the rails for the feet of those wearing one gauge and for the feet of others Free carry with a different gauge, and on the two guide rails according to the different ones Parts of the stretcher feet arranged several times on the rails in longitudinal distances of the stretcher feet behind or overlapping locking elements automatically or by means of a common actuator at the same time "can be locked and unlocked.

The invention achieves that the stretcher is only placed on the stretcher platform or stretcher storage device pushed on and through the central actuation of the locking elements arranged on both rails can be secured, without any conversion work on the stretcher platform or the stretcher storage device, so that different stretchers can easily be used alternately can be.

The locking elements arranged several times on the rails allow different ones to be taken into account Foot shapes and arrangements. In particular, everyone within the North Atlantic Pact (NATO) used stretcher are used, which all have bracket-like feet, but with respect to the Differentiate the distances between the feet in the longitudinal and transverse directions as well as the foot widths and shapes. aside from that In addition to brackets arranged in the longitudinal direction like runners, there are also brackets arranged in the transverse direction are arranged as feet on stretchers. In addition, stretchers used in the civil sector can also be used soft often have castor feet.

With the stop pieces arranged on one of the load-bearing ends are next to different ^ gauges This also takes into account different overhang lengths of the parts of the stretchers that protrude beyond the feet can be achieved that one end of the wearing - for example head or foot end - regardless of respective stretcher type on the stretcher platform or stretcher storage device always approximate occupies the same target position

According to a preferred embodiment of the invention can fix stop pins running in the longitudinal direction of the rails on one end part of the rails be arranged, which in the stretcher transverse direction running foot parts of a type of stretcher when pushed Reach over the stretcher in the shape of a hook and specify the target position of other stretchers simply by means of a stop. This stop pin thus have a double function. On the one hand, they secure one type of wearer against movement forward and upward, while on the other hand they secure another type of carrying only against movement forward.

de bolt links can be bolt slides or pivoting bolt levers and are therefore structurally simple be mechanical parts.

In order to reduce or block movement of the locked stretcher, the locking links Wear resilient stop pieces, which when the stretcher is locked on their frame or foot rests in Stretcher cross direction and / or length direction and / or rest from above.

If necessary, stops are arranged on locking members on one side of the stretcher platform, which the stretcher seek to push sideways in such a way that their feet on a '..äjigsseite against a side wall of one of the guide rails be pushed so that a particularly low mobility in the transverse direction can be achieved is.

The automatic locking members can be resiliently mounted, so that they are when the stretcher is longitudinally displaced can be locked or unlocked by their feet. This makes it possible to use any type of support in the guide rails push in or pull out of these without the stretcher feet by the automatic Lock links would be locked. The automatic locking members preferably have corresponding ones for their deflection Inclined surfaces that interact with the stretcher feet. In order to prevent the locking links with strong accelerations in vertical direction

Direction through the interaction of their inclined surfaces with the foot parts of the inclined to the vertical Stretcher are deflected, are expediently approximately perpendicular to the direction of deflection on the locking members downward facing stop pieces arranged, which foot parts of the stretcher from above reach over and secure the same against vertical movements.

Locking levers arranged as locking members can be C-shaped or hook-shaped and in the locking position through an opening in the guide rails, preferably from the side. protrude. When the latch lever are arranged pivotably about an axis running transversely to the longitudinal axis of the rail, they can in Latch position transversely to the rail axis arranged foot parts overlap and at the same time this or others Reach behind the foot parts so that several directions of movement are blocked at the same time.

A common actuating element for the locking elements is preferably one in the longitudinal direction of the stretcher platform arranged shaft provided on the articulated with the locking members via push rods Arms are rotatably arranged. With this construction it is possible in a simple manner, in the longitudinal direction the guide rails to operate multiple elements at the same time.

To make it easier to put the stretcher on or remove it from the stretcher platform, the guide rails Arranged as a rocker on a carriage that can be longitudinally displaced in guides fixed to the vehicle be, the rocker arranged to extend the car and when retracted in the longitudinal direction of the vehicle Trolley to remove or put on the stretcher can be lowered by pivoting is. In this arrangement, the locking elements and their actuating member are part of the rocker, i.e. H. Actuator and group learning can in principle have the same construction as fixed guide rails.

The rocker is lowered or raised by means of or with the support of auxiliary units. In addition can, for example, a gas spring or a servo motor, z. B. an electric servomotor, between cars and rocker.

The invention is explained below with reference to preferred exemplary embodiments shown in the drawing are shown. It shows

9 is a side view of the invention Stretcher platform and

F i g. 10 is a sectional view corresponding to the section line X-X in FIG.

The stretcher platform or stretcher support device according to the invention has a stretcher table 1. as shown in FIG F i g. 1 is shown in plan view.

This support table 1 consists of two U-shaped guide rails 2 and 3, on which with respect to the direction of insertion the rear end of the carrying a push-on plate 4 is arranged and the multiple with Cross members 5 are connected to one another. The guide rails 2 and 3 expand to form a slide-on plate 4 towards conical, so that the feet of a stretcher placed on the sliding plate without difficulty can be pushed into the guide rails.

The guide rail 2 has a width for the largest occurring foot width of the stretchers used is sufficient. The guide rail 3 is also widened so that both stretchers with the smallest track width as well as stretchers with the largest occurring track width in the guide rails can be inserted. Under the track width, the distance between the stretcher feet is in crosswise direction of the stretcher Understood.

In the front end region of the guide rails 2 and 3 facing away from the push-on surface 4, the Rail width narrowing stop pieces 10 and 11 are arranged, which each front inclined surfaces 10 ' or ti 'own. The stretchers with a relatively large overhang with a narrow gauge can therefore only be pushed up to the inclined surfaces 10 ', stretchers with maximum track width only up to -. '«. τ inclined surface 11'; and stretchers with one middle gauge can be pushed into the narrowed area between the stop pieces 10 and 11, until they hit the stop pin 12, the guide rails 2 and 3 at the end in the longitudinal direction of the rails are arranged at a distance from the guide rails.

With certain types of wear, e.g. B. those with transverse to the longitudinal direction of the stretcher bow-like feet, the stop pin 12 overlap foot parts extending in the transverse direction of the stretcher, so that the stretcher is locked against movement at the top. In other stretchers, however, the stop pins 12 only act as stops, so that only a movement of the stretcher in the direction of the stop pin 12 is prevented.
Furthermore, locking slides 6, 6 'to 6'"and locking levers 7 to 9 are arranged on the guide rails 2 and 3, some of which are shown in more detail in FIGS.

The locking slide 6 to 6 '"and the locking lever 7, 8 are jointly by means of a shaft 13 through Pivoting of the handle lever 14 actuated. For this purpose, arms 15 are non-rotatably arranged on the shaft 13, α «: over Push rods 16 are articulated to said locking slides or locking levers 7 and 8 are. The arms are expediently arranged in such a way that they are in the locking position of the locking slide 6 up to 6 '"or the locking lever 7.8 in an over-center position stand.

As the F i g. 2 shows, the locking slides 6 and 6 'can be turned into a «by rotating the shaft 13 in the direction of the arrow. Release position are withdrawn, which is shown dashed line for the bolt slide 6 ', wöbe at the same time the locking lever 8 is pivoted outward into its <release position. The bolt slide ( and 6 'move into sleeves 17 and 17', wel before being arranged laterally on the guide rails 2 and 3 are net.

Between the bolt slide 6, which according to FIG. screwed to a T-shaped connector 24

which are articulated to the push rod 16 is, a stop piece is on the connecting piece 24

18 arranged, which is moved with the bolt slide 6 and due to its opposite to the bolt slide 6 deeper arrangement, compare F i g. 3, with certain types of stretcher laterally against in the longitudinal direction of the stretcher running foot parts 19 which overlap the locking slides 6 in the locking position will. The locking slide 6 together with the bottom surface of the guide rail 2 prevent a Vertical movement of the foot part 19 and thus the stretcher, while the stop piece 18 together with the opposite vertical wall 3 'of the guide rail 3 a sideways movement of the foot part

19 prevented. At the same time, the locking slide 6 can grip in front of or behind vertical foot parts 19+ and one Prevent movement in the longitudinal direction of the rail.

The locking slide 6 "and 6 '" work in the same way as described for the locking slide 6 and 6', respectively became.

The locking lever 8 is used to secure an axle pin 20 on stretchers with roller feet. To do this, points the locking lever 8 has an opening 21 into which the journal 20 when the locking lever 8 is pivoted into the shown locking position is inserted, compare F i g. 2.

In order to ensure that the journal 20 is exactly opposite the opening 21, is shown in FIGS. 1 and 2 arranged diagonally opposite the automatically acting locking lever 9 on the guide rail 2, which in both figures occupies its locking position. This locking lever 9 acts with the diagonally opposite one Roller foot of the stretcher together and engages behind and over the corresponding axle journal 20 '.

For this purpose, the locking lever 9 according to FIG. 2 a groove 22 open in the direction of the push-on plate 4, see above that the journal 20 'on the one hand against a movement in the direction of the facing away from the sliding surface 4 The end of the guide rails and on the other hand is blocked against vertical movements.

By recognizable in Fig. 1 inclined surfaces 9 'it is achieved that the locking lever 9 against the force of a Spring 23 is deflected outward in the direction of the arrow when stretcher with other types of feet is longitudinally displaced will. The locking lever 9 thus only acts as a lock for stretchers, which roller feet with axle journals 20 ' exhibit.

The F i g. 5 and 6 show the also in FIG. 1 recognizable locking lever 7, which is C-shaped and on a tab 26 arranged on the rail 2 about an axis perpendicular to the bottom of the rail 2 is pivotably mounted. This latch lifter! 7 is pivoted by means of the push rod 16, the dashed line Representation shows the release position, while the representation with solid lines shows the locking position reproduces In the locking position, the locking lever 7 engages with an angled arm through a opening 27 in the side wall of the guide rail adjacent to the tab 26 and overlaps with its angled end 28, a foot part 19 'of a stretcher type extending transversely to the longitudinal direction of the rail with bow-like feet arranged in the transverse direction of the stretcher. At the same time, the locking lever engages behind 7 a vertical foot part 19 ″, so that the stretcher cannot slide backwards from the table 1. In the Front feet of this stretcher grip the previously mentioned stop pins 12, which this type of stretcher prevent vertical movement and forward movement.

In the modified embodiment according to FIG. 7 are the locking slide 6 "and shown in Fig. 1 6 ′ ″, which are actuated simultaneously via the shaft 13, by automatically acting resilient locking levers 29 and 29 'replaced, the locking levers 29 being arranged on between the guide rails 2, 3 on their side walls angled flat pieces 30 are arranged pivotably about an axis perpendicular to the rail floor are, while the locking levers 29 'are pivotably mounted on the stop pieces 10. Between one arm of the locking lever 29 and 29 'and one arranged on the guide rails 2 and 3 stationary Arm 31 is each clamped in a tension spring 32, which seeks to pivot the locking levers 29 and 29 'so that whose triangular locking plates 33 lie over the guide rails 2 and 3. On these triangular ones Locking plates 33 are located downwardly facing locking pins 34. In the locking position shown these locking pins 34 overlap foot parts of certain types of support that extend in the longitudinal direction of the rails, so that a vertical movement of the corresponding foot part is impossible. With longitudinal displacement of the The locking levers 29, 29 'on the locking plates 33 are counteracted by their inclined surfaces 33' the force of the springs 32 pivoted so that the stretcher feet on the locking levers 29, 29 'pass and a The stretcher can be pulled out or pushed in. Figures 9 and 10 show a tiltable arrangement of the table 1 on a carriage 35 which is longitudinally displaceable in C-shaped guides 36 fixed to the vehicle on rollers 37 is arranged. At one end of the carriage 35, angle brackets 38 are in joints 39 around the transverse axis of the carriage pivotally arranged. The table 1 is mounted on these angle supports 38, the front part of which is on the carriage 35 rests when the angle brackets are pivoted up.

If the car is pulled towards the rear of the vehicle, the bracket 38 with the one mounted on it protrude Table 1 out of the open rear of the vehicle and can be swiveled down into the inclined position shown in dashed lines so that a stretcher, not shown, is pushed onto the table 1 more easily or can be removed from table 1.

In order to enable the table 1 to be pivoted with little effort, a gas pressure spring 40 or 40 'is provided, which - as shown - supports the angle bracket 38 against the carriage 35 or at the front end of the table 1 is arranged and that

so seeks to pull the front end down onto the carriage.

Instead of a gas pressure spring, an electric or hydraulic servomotor can also be used.
