Description

Door lock for large-capacity containers and trucks The invention relates to a door lock.

The doors of large-capacity containers, or so-called containers of trucks are usually provided with worn out, their closing effect on it is based on the fact that locking rods with the upper and lower belt by a twist grip the door opening with appropriate eyelets or attached elements for engagement to be brought. For example, the twist grip is swiveled horizontally, which means Hooks or claws engage in corresponding elements of the upper and lower belt.

Another possibility is to swivel the rotary handle vertically, whereby the push rods are shifted up and down and slide into corresponding openings or attached eyelets. The first solution (rotatable hooks and claws) has the disadvantage that either too large an incision has to be made in the upper and lower chords and the same has to be weakened enormously, or a corresponding element has to be placed on the upper and lower chords, where- through the entire closure must be built in front of the container or truck, which increases the risk of damage and accident enormously.

The second option, to work with push rods, has the advantage that the opening in the upper and lower belt is relatively small, but has the disadvantage that with this design no proper clamping effect is achieved even with a conical rod tip, which is because of large containers and trucks the tightness is of great importance. With eyelets or bolts placed on the upper and lower belts, the entire neglect has to be paid for again, which is problematic for the reasons mentioned above.

Bearing effect in the upper and lower belt - the door firmly welded in action. With this function one achieves a secure and tightly closing lock, with perfect clamping function, with great protection against accidents and damage with little weakening of the upper and lower belt. Fig. 1 shows the lock (1) in longitudinal section. A square (3) sits in a housing (2). The handle (4) is connected to the square (3) by a fork (5). The square (3) is turned by the handle (4) and the fork (5). On this square (3) there is a tab (6) on which two other tabs (7) are hingedly attached. These tabs (7) are articulated to the push rods (8) which move in the bearings (9). The bearings (9) are attached to the door plate (16).

An eccentrically acting clamping element (11) sits at the head of the push rod. By moving the handle (4) vertically, the push rods (8) are pushed up or down. By moving the same in the horizontal, the push rods (8) and thus the ex entrisch acting clamping element (11) are rotated. After it has passed through the opening (12) of the upper and lower belt (13), which has a cap (14) as a counter-bearing for the eccentric effect , this tensioning element (11) is pressed by turning these caps (14). to clamp the door (15), from. Fig. 2 shows the arrangement in perspective. Fig. 3 shows another possibility for realizing the basic idea. A disk (2), which is provided with two cutouts (4) , whose central axes are continuous from the center of the ball , rotates around a ball (1) 9 which is connected to the door plate (3) via the bolt (2a) (1) change their spacing. From point 6 to point 7 it decreases continuously. By moving the handle (8) vertically , the push rods (9) are moved vertically. By turning the handle (8) horizontally, the eccentrically acting clamping element (10), which is attached to the push rod (9) , also rotates when it is attached to the disc (2) via the round bolt (13) , brought into its tense position . The eccentric clamping element (10) is pressed by rotation on one of the upper. (12) and 'lower belt (12) attached cap (11) 9 to brace the door. Fig. 4 shows a learning path in which the rods (2) can be moved and rotated by moving the handle (1) in a plane (in the example shown, the vertical movement is shown. The horizontal movement is also easy to implement. Only the handle mechanism is changed slightly) is possible. Due to the thrust of the partially threaded (4) designed push rods (2) which are rotated by a correspondingly shaped bearing (3) when the threaded (4) parts enter when the main handle (1) is operated, a push rod (2 ) fixed exentriech acting clamping element (5) used to Ansurren the door (7) by reaction, in the upper and lower flange (6).

It is possible to form the tensioning element on the push rod and the catching eye in the upper and lower belt sections.

Claims (1)

Door lock, in particular for use in large-capacity transport containers, containers and trucks, characterized in that both vertically displaceable and rotatable push rods provided with eccentric tensioning elements slide into the openings in the upper and lower chords and with the eccentrically acting tensioning elements through counterbearing action in the upper and lower chords Achieve tensioning effect, the door to be locked is locked and tightly closed.
