  • gas can escape in such a case, which on the one hand is economically disadvantageous and on the other hand, from a safety point of concern.
  • the present invention has for its object to provide an improved connection coupling for the detachable connection of a fluid container to a fluid inlet nipple, which is safe and easy to handle, while ensuring that the fluid container can not be removed before the extraction valve is fully closed.
  • This object is achieved with a connection coupling according to claim 1.
  • Advantageous developments of the invention are the subject of the dependent claims, including including a bottle change system formed therewith.
  • the shut-off element is connected to a first securing element and the coupling element has a second securing element, wherein the first securing element is in engagement with the second securing element when the blocking element is in the open position and the coupling element is in the locking position and preferably forcibly disengaged from the second securing element as soon as the blocking element is in the closed position.
  • the coupling element can only be actuated to remove the fluid container when it is ensured that the shut-off element is completely closed and the coupling element has released by the engagement of the two securing elements has been solved.
  • the handling is particularly simple if the disengagement takes place automatically or forcibly, but it can also be advantageous if the process of disengagement has to be triggered by the operator himself.
  • a particularly simple to manufacture and to use embodiment is obtained when between the shut-off and the coupling element, a movable sleeve is provided, on which an engagement projection is the first securing element, which engages in a corresponding recess as a second securing element in the coupling element when the sleeve in the open position and the coupling element are in the locked position.
  • the sleeve is designed as a sliding sleeve and also the coupling element is provided with a sliding sleeve surrounding it, in which the recess is located.
  • connection coupling can be made particularly compact if the coupling element surrounding the second sliding sleeve perpendicular or at least substantially perpendicular to the first sliding sleeve is arranged and the recess is formed as an annular groove in the second sliding sleeve, engage in the engagement projection and possibly even audibly engage.

  • this second sliding sleeve can be actuated to separate the fluid container.
  • connection coupling can be further increased if the shut-off element is rotatably arranged together with the rotary handle and the sliding sleeve and the fluid container around the longitudinal axis of the second sliding sleeve.
  • This rotatable arrangement is particularly advantageous when two connection couplings according to the invention are arranged with their Fluid broughtem side by side with approximately axially aligned first sliding sleeves. In this position, the space required is minimized perpendicular to the axis of the first two sliding sleeves. If the space requirement in the axial direction of the first sliding sleeves is to be reduced, it is sufficient to turn the two fluid cylinders towards each other, in each case about the longitudinal axis of the second sliding sleeve.

  • a fluid container 11 may be tightly closed by a shut-off element 20, which is designed in the form of a valve not shown in the drawing, which is actuated via a rotary handle 21 or opened to remove gas from the fluid container.
  • the gas is then directed to a manifold 42 (see Fig. 2) from which it is fed to a vehicle piping system, indicated schematically by reference numeral 44.
  • a fluid inlet nipple 12 At the distributor 42 there is a fluid inlet nipple 12, of which only one connecting screw can be seen here.
  • connection of the fluid container 11 to the fluid inlet nipple 12 is effected by means of a coupling element 30, which is formed in a manner known per se with a sliding sleeve 32 which surrounds it. If this sliding sleeve 32 is pulled down, the line connection between the connection nipple 12 and the fluid container 11 is separated, and the fluid container 11 can be lifted upwards. The renewed application of the fluid container 11 then takes place in that it is attached with its pipe section 16 to the upper end of the sliding sleeve 32 and pressed down, whereby the coupling element 30 restores the line connection.
  • the fluid container 11 should only be disconnected if it has previously been closed by means of the rotary handle 21. To ensure that the fluid container 11 does not accidentally remain open prior to separation, the known connection coupling has been further developed.
  • a circular disc 23 is rotatably connected, which on one side (shown here in Fig. 1 left) has a flattening 22, by which the circumference of the circular disc 23 is reduced.
  • Fig. 1 shows the rotary handle 21 and the circular disc 23 fixedly connected to it in the open position, ie, the shut-off element 20 is in an open position in which gas can be removed from the fluid container.

  • a first securing element 24 in the form of an engagement projection 26, which may be formed in a particularly simple design as a bolt.
  • the engagement projection 26 engages in a corresponding recess 36 in the coupling element 30 a.
  • the cooperation of the first securing element 24 with the second securing element 34, i. the engagement of the engagement projection 26 in the recess 36 causes the substantially perpendicular to the sliding sleeve 28 arranged sliding sleeve 32 in this position can not be pulled down by engaging an annular bead 38 down to unlock the coupling element 30.
  • the position of the sliding sleeve 32 shown in FIG. 1 thus represents its locking position, in which gas can flow from the fluid container to the fluid inlet nipple 12.
  • the sliding sleeve 32 Only then can the sliding sleeve 32 be pressed down into its removal position, in which the fluid container 11 can be removed.
  • the sliding sleeve 32 is also acted upon by a spring arranged in its interior, namely in the upward direction into its locking position. This ensures that the sliding sleeve 32 and thus the coupling element 30 are normally in the locking position.
  • the recess 36 is formed in this embodiment as the sliding sleeve 32 encircling annular groove which is bounded at its upper end by an annular bead 37. From the above illustration it can be seen that no exact right angle between the sliding sleeve 28 and the sliding sleeve 32 must be maintained. It is only necessary that the function of manufacturing and the solution of the engagement between engagement projection 26 and recess 36 is ensured. In this embodiment, the engaging projection 26 is automatically disengaged from the recess 36 when the fluid container is completely closed. This facilitates handling.
  • An empty fluid container 11 can either be refilled via a refueling nipple 14 at a gas station, or it can be exchanged for a corresponding full fluid container 11 after disconnection. If two such bottles or fluid containers 11 are provided, as shown for example in FIG. 2, alternatively the two fluid containers can be filled via a common refueling nipple 46.
  • a bottle change system is formed in an advantageous manner, in which the fluid container for mobile or stationary applications can be replaced quickly and safely regardless of a gas station, but can also be quickly filled at a gas station on the common refueling nipple on the vehicle.
  • the sleeve 28 are replaced with the engaging projection 36 by an acting on the hub 23, preferably spring-loaded, push rod which can engage in the recess.

  • a direct attack or engagement of the two sliding sleeves can be provided to each other or into each other, or the two sliding sleeves have no contact with each other.
  • these variants should also be protected; that is, used in claim 1 formulation "in engagement 1 should also be considered by the above-described blocking the movement of the sliding sleeve 32 by attacking the sliding sleeve 28 or by the function of the sliding sleeve 28 as a blocking element against movement of the sliding sleeve 32 as with ,
