Central belt buckles, in particular for parachutists' body harnesses

The invention relates to a central belt lock, in particular for falcon jumper body harnesses, for quick and simultaneous use releasable connection of several with connecting pieces twisted, at a central point converging straps, with a lock housing and a centrally mounted in Direction of its longitudinal axis displaceable, rotatable main pin, the outside of the lock housing to a turntable Actuation of the lock carries and is within the housing with an anchor plate in connection, which preferably four parallel to the Ilauptzapfen in the lock housing movable anchor bolts leads, which in their one end position an associated Mesh through the transverse slot in the housing for inserting the connector of the belt in question and thus centralize the belts stick together and in their other end position from the Slot are removed so that the belts can loosen from the lock.

Central belt locks of this type are known (German Patent 651 575, German Auslegeschrift 1 002 632, British Patent 577 503). If the turntable is operated in the prescribed manner with such central belt locks - no. In this way, the lock as such remains alone and usually falls off the body of the parachutist. This usually involves the loss of the lock.

To avoid this loss it has already been suggested (Swiss patent 155 662) that? ⁵ lock housing with a special insert (Fig. 7, Bpzugzeichen 56) to be provided, which has a slot (57) through which a special tether (Fig. 1, reference numeral 14) is looped, which is independent of the anchor bolts and on which the lock gets stuck after triggering. However, this has the disadvantage of an additional structural effort on the lock housing and, above all, an obstruction when quickly putting down the harness, because the special retaining strap must in turn be connected to the harness, which is done by a cross strap (13), which in turn with two of the star-shaped is connected to the middle of the body and thus to the lock extending straps, so that they can not move freely.

In the aforementioned known central belt lock itn rest provided that the anchor plate with the anchor bolt consists of one piece (Fig. 9). This results in a simplification the internal structure of the central belt buckle.

The invention is based on the object of developing a lock of the type po mentioned at the outset that there is the possibility of

2098U / Q04I

To let it stay in contact with the loosened harness and thus prevent the lock from being lost, for this purpose however, to make no special tether necessary. The lock should be simple in structure and unchanged in weight to be operated.

The solution is done according to the invention by a central belt buckle of the narrower genus mentioned at the beginning with the characteristic that in the lock housing above at least one anchor bolt a holding member is arranged which follows the movements of the anchor bolt when the lock is operated, so that when Removing it from the slot in its place enters the retainer into the slot and holds the strap connector in place.

This not only completely solves the problem posed, but also has the advantage that the lock on any connection piece as desired or the belt can get caught when it is triggered. The reason for this is to be seen in the fact that to hold on to the Castle one of those anchor bolts or a kind of artificial extension of the same is used, which anyway to hold the normal connection belts and must be present. When putting on the harness, you only need to ensure that the connector on which the lock is to get stuck later, is engaged in the correct anchor bolt, which is indicated by a suitable marking, z. B. color marking, can be easily achieved.

According to a preferred embodiment of the invention it is provided that in the alignment of an anchor bolt above its locking position in a hole in the lock housing Holding bolt is mounted, which move in its longitudinal direction, following the movements of the associated anchor bolt

and is so long that it rests with its lower end on the tip of the anchor bolt and with its upper end rests against the underside of the turntable.

In this way, only a single additional component is required to communicate the main features of the invention to the lock. Even leave existing locks convert to the new design with little effort. All you need is a hole to mount the retaining bolt in the lock housing to be drilled, whereupon the retaining bolt is inserted and the turntable is reattached. the The turntable then holds the retaining bolt in place and also causes its longitudinal movement and thus its effectiveness The constant contact between the retaining bolt and the anchor bolt is maintained by the compression spring for the anchor bolt in question.

Another embodiment of the invention is characterized by this from the fact that the anchor plate with the anchor bolts consists of auejfeinem piece in a manner known per se. This has the advantage of a particularly simple construction, because the number of parts in the lock is significantly reduced by this measure. However, the invention works just as well with locks Anchor bolts that are not firmly connected to the anchor plate, but have a cross-shaped anchor plate, the ends of which the Guide the anchor bolt like a fork.

According to the invention it can also be provided that the retaining bolt is frustoconical on its side facing the anchor bolt and on its side loaded by the turntable. is convex. By this measure, the mobility of the retaining bolt in the housing is improved and thus the Increased security of the correct function of the central belt buckle.

Finally, the invention also includes an exemplary embodiment, which is characterized in that the diameter of the retaining bolt is smaller than the diameter of the anchor bolt. This results in a material saving, because the retaining bolt only needs to absorb small forces during the Anchor bolt must bear its full proportion of the weight of the body and equipment of the parachutist.

In the drawing, an embodiment of the invention is shown, which is described in detail below ι will. The figure shows a central belt lock in side view, partially cut vertically, with an inserted connector, in the not yet released position.

A lock housing 1 with the well-known square G-Rundrißgestaltung is centrally provided with a main pin 2, the top of a circular turntable 3 for actuating the f Lock by hand. A guide pin 4 - in the drawing only recognizable with its end face - is used for Evocation of clearly noticeable detent positions when turning the turntable 3. Inside the bottom by a cover 5

Enclosed housing 1 supports a cross-shaped anchor plate 6, which has four anchor bolts 7 which are made in one piece with the anchor plate 6. The anchor plate 6 is in the middle with the lower end of the main tap _j 2

independent S in movable connection, so that the turntable / from the J The anchor plate can be rotated and moved with the anchor plate. Each anchor bolt 7 has a recess at the bottom for receiving it of the upper end of a helical compression spring 8, which the respective anchor bolt and thus the anchor plate as well push the main pin and the turntable upwards.

The housing 1 is in the area of the anchor bolts 7 with transverse slots 9 provided, which are so large that an eye-shaped a

2098U / 004

Connection piece 10 of the belt 11 in question pushed in so far can be that the eye is penetrated by the respective anchor bolt 7. The anchor bolts 7 are upwards beveled on the outside so that they are pressed down when inserting the connecting pieces 10 until they are in the eye can snap up again.

Coaxially with an anchor bolt 7, a bore 12 is made above this in the housing, in which a retaining bolt 13 stores, which is frustoconical at the bottom and rounded at the top is. The Halteboizen 13 has such a length that it has the intended space between the upper edge of the Anchor bolt 7 and the lower surface of the turntable 3 fills, so that a positive connection from the Cover 5 over the spring 8, the anchor bolt 7 and the retaining bolt 13 to the turntable 3 results. The retaining bolt 13 is standing in other words, in constant contact with the anchor bolt

When the central belt lock is triggered, the turntable 3 is first rotated in a known manner by a quarter of its circumference and unlocked and then pushed in towards the housing 1. The main pin 2 pushes the anchor plate 6 against the pressure of the springs 8 downwards, the anchor bolts 7 move downwards out of the slots 9, and the belt connectors 10 stored therein can leave the slots. However, this is not possible for the anchor bolt 7 that is in contact with the retaining bolt 13, because by pressing the rotary disk 3 in, the retaining bolt 13 is moved downward and into the relevant slot 9 - continuously following the descending anchor bolt 7 until the retaining pin 13 with respect to the h lachlußstück 10, the location of the anchor bolt 7 einriimtnt and prevents ,, that the Anschlußetück may emerge from the slot.

If the central belt buckle is then used again to put the harness on a jumper again, the "Turntable 3 turned back in a known manner until the anchor plate 6 is released and can move upwards under the pressure of the neon springs. The anchor bolt in question pushes 7 the retaining bolt 13 - following the turntable 3 above, bo that last the position shown in the drawing is reached again.

The in the above description, in the drawing and in The features of the subject of the application disclosed in the following claims can be used individually as well as in any Combinations with one another for the implementation of the invention in its various embodiments be essential.
