Previously, French patent publication 1,190,878 discloses a cylinder lock mechanism which acts on both a long latch lock and a latch, both separate mechanisms being included in the same lock housing. The long-latch mechanism is controlled by a key through a cylinder lock, which in practice means that only a small force can be transferred to the long-latch mechanism. However, the long latch devices often tend to get stuck, which means that in many cases an infinite amount of force is required to bring the long latch lock housings into the latch position. For this reason, among other things, the system is unsatisfactory.

German patent publication 729 326 discloses another structure using two separate lock cases. This German patent publication does not provide a solution to the problem of how the long latch and latch mechanism could be placed in the same lock case. Instead, it is required that each of these mechanisms requires a separate standard type lock case, and their simultaneous operation is made possible by placing the control members of the long-latch mechanism on each side of the lock case itself.

German patent publication 165 023 discloses a long latch in which the latch bar consists of a pivot axis which can be moved to its latch position by a notch in the push rod located in the lock housing. Also, this patent does not explain the long latch mechanism located in a single lock case.

According to one embodiment, British Patent Publication No. 583,821 discloses a long-latch structure having roller-shaped axes that are vertically displaceable. According to another embodiment, the long latch axes are reversible. In both cases, there is some kind of central pivot bogie, but they do not have separate control mechanisms for different bogies and, in particular, they do not have mechanisms located in the same lock case.

German Offenlegungsschrift No. 1,907,061 describes a system in which the same steering mechanism acts on both the long-latch movable handlebar and the linearly movable latch bar. The device thus lacks a turntable according to the present invention.

Other types of locking devices are disclosed in U.S. Patent No. 2,854,837 and Swedish Patent No. 388,898.

An important disadvantage of prior art systems is that their swivel mechanism, if any, cannot be locked.

It is an object of the present invention to provide a lock structure of this type which overcomes the above and other disadvantages of previously known lock devices, enables a tight and reliable double lock structure comprising both a long latch and a lock cylinder lock in the form of an inverted latch bogie and which allows the lock to reliable and inexpensive operation of the locking devices without one of them adversely affecting the operation of the other.

A locking device according to the present invention which fulfills the above purpose is known from the combination shown in the characterizing part of the appended claim.

An embodiment of the invention will now be described in more detail with reference to the accompanying drawing, in which Figure 1 shows a perspective view of a partially cut-out lock housing with both a long latch control mechanism and a weight cam device for actuating a latch bar.

Figure 2 shows a side section of the lock case according to Figure 1.

The lock case 1 has a push cam 2 for a long latch provided with three axles, one of which is indicated by the number 21 shown in Figure 1. This bar is preferably a short distance from the lock housing, while the other two bars are a longer distance from the lock housing to the ends of the handlebar 20. under.

The push cam 2 is connected via a guide arm 3 to a connecting rod 4, which connects the two handlebar parts 20 on different sides of the lock housing. The movement of the weight cam 2 in both directions is limited by the mating pins 9, 10. As the weight cam 2 moves in the other direction, locking is achieved by self-braking of the long latch locking rollers 21. This means that by acting on the locking tent, for example with a knife or the like, the handlebar cannot be moved so that the axles open.

The handlebar 4 moves inside the lock housing 1 at a short distance from and parallel to the breast plate 16 belonging to the lock housing. The breast plate 16 has an opening 16a for a bar 18 to be pivoted out of the lock case. The length of the opening 16a is considerably greater than the height of the pivots 18 in the latch position, i.e. the dimension in the direction of the length of the breast plate 16.

4 74322 This beam 18 is acted upon by a weight cam 12 with teeth 12a, which acts on the pivot bogie via a pin 12b and a so-called transfer slot. The teeth of the weight cam 12 communicate with the corresponding teeth of the linearly movable rack member 13, which is acted upon by a guide member 14a on the circumference of the inner part of the lock cylinder 14. The inner part 14 of the cylinder can be acted on from outside the lock housing with a key 15. Possibly there may be two lock cylinders, one on different sides of the linearly moving control member 13, the system operating so that the complete movement of the member 13 is achieved by turning the lock cylinder one turn.

The weight latch 2 of the long latch is actuated from outside the lock housing by a handle 6 through a square pin 5, which handle is provided with a shaft 6a passed through the handle washer 7.

The connecting member 4 connecting the two handlebar parts 20, one of which is on each side of the lock housing, is provided with a longitudinal central notch 4a for the pivot barrel 18. According to a suitable further feature of the invention, the length of the notch 4a is greater than the length of the opening 16a in the breast plate. The turntable can then operate completely freely, regardless of whether the locking latches 21 of the long latch are in the neutral or latch position.

On the other side of the lock housing, instead of a lock cylinder, there may be a handle (not shown) by means of which the turning tent 18 is actuated.

The position of the locking cylinder can be influenced on the pivot in other ways, for example by means of a handicap system. Instead of the position of the connecting rod 4, the level of which coincides with the plane of the breast plate 16 of the lock housing, other types of connecting members can be used between the handlebar parts 20. Optionally, a single handlebar may be used, which in that case is suitably taken out of the way of the pivot 18 and the members in the lock housing acting on it, as well as the weight cam 2 which acts on the handlebar of the long latch.
