Rotary bolt lock especially for windows on caravans and the like

In a housing screwed onto the inside of the window Rotary latch is mounted on a handle that can be pivoted through about 90 degrees into the Closed and open positions can be rotated and determined.

The solder -Geststellung is to cause the central projecting the rotary latch from the center of the bearing pin by Here> nPress only from the inside of the window forth a projecting push-button.

The push button has a square neck or a coupling part attached to a guide plate which is guided in the housing in a longitudinally displaceable manner under the action of a compression spring. By means of a snap-in designed The housing is closed from below on the base plate.

Quarter-turn locks that can be locked or locked are known per se. In the case of the closure according to the present innovation, in which all parts are made from finished plastic molded parts with high strength, The advantages are based on the fact that all the individual parts are interlocked and snap together are mountable and by means of the mounting screws be held together on the window frame at the same time.

The drawing represents the innovation in an exemplary embodiment. It shows:

Figure 1: The twist lock in the view and partially in longitudinal section when closed.

Figure 2: The top view of the closure.

The five components as a plastic injection molding of the closure according to the Innovation are

the housing 1,

the bolt part 2,

the snap fastener part 3,

the bottom part 4 and

the compression spring 5, made of steel.

III Il

The housing I has a screw-on foot 6 with screw holes 7 and has a central bore 8 for receiving the locking part 2 on its pivot 9 from above. The locking part 2 has a known locking arm Io and a handle II.

On the pivot 9 protruding lugs 12 and 13 are at the end for retention Shaped in the axial direction, for piercing the bearing pin the central bore 8 of the housing 1 with two longitudinal grooves 14 and 15, provided, which run out into a bore 16 of the housing, which is gradually enlarged from below.

steadily
The snap fastener part 3 3 | e> in a central bore of the locking part 2 and protrudes with its tip from the front surface. In the central area, the snap fastener part 3 has a square 17 which engages in a locking manner in a matching square hole 18 of the central bore 8 of the pivot pin 9. Uas push button part 3 carries a plate 19 with guide grooves 20 and 21 in its lower region.

On the round bottom part 4, a circumferential bead 22 is formed, which in a corresponding groove 23 of the housing I can be clipped non-rotatably. On the bottom part 4 are two long, protruding, sharp-edged guide wedges 24 and 25, which engage in the guide grooves 20 and 21 of the plate 19 of the push button parts 3 and guide in a non-rotatable, but longitudinally movable manner.

The upper ends of the guide wedges 24 and 25 fit, tapered accordingly, into the grooves 14 and 15 in the central bore 8 of the housing 1 and are held reinforced.

The compression spring 5 is the only steel part on the one hand in a central recess 24 with pin 25 of bottom part 4 and, on the other hand, in a guide bore 26 of snap fastener part 3.

During assembly, the locking part 2 is from above on the housing 1 with the Trunnion 9 inserted and rotated so that the openings are closed from below will. Parts 3, 5 and 6 are assembled from below.

Claims (4)

• «■ * · t · ♦« lit · fl Dietrich Lüttgens GmbH & Co.KG · ,, ·; Talburgstraße 46 Heiligenhaus on October 05, 19B3 claims for protection 1. Quarter-turn lock made of plastic parts, especially for windows on caravans and the like, with a turning lock mounted in a housing that is screwed onto the inside of the window frame, which is pivoted on a handle by about 90 degrees in the closed and open position and can be determined, characterized in that the individual parts (1 to 5) inserted into each of the closure, are caught and finally fastened by screwing on the frame. 2.
