Description

72587

This invention relates to a gun valve locking device according to the preamble of claim 1.

5 Known devices of this kind, in which the shut-off trigger is allowed to co-operate with a simple notch in the valve body, have the disadvantage that when the trigger is retracted and released at the desired time of dispensing, i.e. in the desired valve position, the trigger tooth portion engages undesirably. far too easily re-into the notch, as a result of which distribution is not interrupted as intended.

The object of the invention is to eliminate this disadvantage of the known closing devices.

According to the invention, the object is achieved by a locking device having the features set out in the claims.

The invention will be explained in more detail below with reference to the accompanying drawings.

Fig. 1 shows a gun valve in which an embodiment of the locking device according to the invention is in a position which closes the inlet.

Figure 2 shows the same embodiment in the locked position.

Figure 3 shows another embodiment in which the closing position of the inlet is shown by solid lines and the locked position by broken lines.

Figure 1 shows a pistol valve for motor fuel with a body 1, 30 an outlet pipe 2, a supply pipe 3 and a valve mechanism 4 placed between these pipes 2 and 3. This valve mechanism is loaded to prevent entry which load can be removed by , someone presses the valve arm 35 line 7, whereby the valve can be opened by pulling the trigger from the front position (solid lines in Fig. 1) 2 to 72587 to the rear position (dotted lines in Fig. 1) or to the locking position (Fig. 2). The trigger groove has a suspension part 6a and, for the finger grip, a U-shaped bracket part 6b, which lower end. is articulated by means of a pin 8 to the suspension part 5 6a to pivot the trigger in said plane of movement.

Thus, the bracket 6b forms a two-arm lever, one lower arm 6c of which is a toothed arm that pivots or pivots into a locking means in the body, and the other, upper arm is a guide arm that pivots the toothed arm 6c away from the tooth when pressed with the finger. This position opens the valve.

The structure described above is conventional and should not be considered further.

In a first embodiment of the invention, the front end of the gripping arm 6c is bent downwards and adapted to tooth a locking stop 9 placed between the thicker front part 9a and the thinner rear part 9b of the circular pin fixed to the body 1.

On the thinner part of the pin, a sleeve 10 is slidably mounted 20, which is pressed by the spring 11 to a position where part of the front edge surface 10a of the sleeve is pressed against the stop 9.

In the example shown, the spring is a coil spring which, around the thin part 9b, rests on one end against the stop in the inner wall of the sleeve and on the other end rests on the run-25. The outer diameter of the sleeve is larger than the outer diameter of the thick part 9a. a response to the downwardly bent surface of the toothing arm 6c when the toothing arm 6c is in the downwardly bent position.

30 When the gun valve opens. j jing, pull the trigger 6 backwards normally. If the trigger is to engage in the toothing position, the toothing arm 6c is turned down and when its downwardly bent end has met the abutment on the front edge surface of the sleeve 10, 35 is pulled back, now against the action of the spring 11, and the toothing arm 6c is pivoted further. downwards and into the inlet in the toothing stop 9 between this stop and the front edge surface 10a of the sleeve. The trigger is now released so that the bent end engages the stop 9. The trigger can now be released completely, leaving it in the locked position.

When the user wishes to interrupt the dispensing, the trigger 6 is gripped again and the toothing arm 6c is turned away from the toothing by means of the guide arm 6d with the stop 9. The spring 11 pushes the sleeve forward until the outer part of the front edge of the sleeve rests towards the stop 9, whereby the sleeve 10 prevents unintentional entry of the re-bent end.

It is obvious that this entry is also prevented if the trigger is not read, but is pulled from its front position without the above-mentioned bending of the toothed arm 6c to the position shown in dotted lines in Fig. 1 and allowed to interrupt the distribution if desired. The trigger can thus return to its forward position without the risk of it being undesirably locked to the locked position.

To avoid the rare possibility that after the trigger is gripped to stop dispensing, the toothed arm 6c is continued to be depressed in an unnatural manner, while the trigger is pulled back 25 to end the locking state, the thin portion 9b may have an upwardly directed cam surface 9d.

The sleeve 10 does not necessarily have to be loaded by a spring, but in its oblique position shown, gravity can preload the spring so as to close the access to the stop 9.

In the embodiment according to Fig. 3, a housing 12 is attached to the gun valve body 1 to a flat spring 13, the front end of which is fixed, for example, with rivets to the housing separately from the housing roof part 12a and whose rear end rests against the inside of the second roof part 12b. Between said ends, the spring 13 has a space between the roof parts 4 72587

It has a protruding protrusion 13a intended to engage the locking arm 6c of the trigger bar. The inlet 14 of the front end 6c of the locking arm is located between the spring 13 and the housing roof part 12a.

5 To lock the trigger in a position where the valve remains open, the spring is pressed at the protrusion by means of the locking arm 6c and this arm is released or moved forward into said inlet opening, the spring keeping the arm toothed in the roof part 12b. When the noble winding is to end, the trigger is pulled back, whereby the spring 13 springs up and closes the inlet 14.

Claims (4)

5,72587 A locking device for gun valves 5 dispensing flowing media, in particular motor fuel, which locking device is formed to lock the gun valve trigger (6) in the valve-open position by means of a trigger connection (9) between the trigger part (6c) and the gun valve body (1) , wherein the locking device has an inlet 10 for said trigger part for locking, characterized in that the locking device further comprises a safety device (10, 13) preloaded to move to the closing position of said inlet and can be taken out of the inlet by means of a trigger part (6c) due to a force effect in a direction different from the normal triggering direction of the trigger and the return direction, for which purpose said trigger part (6c) is movably mounted.
