Description

[Technical Field]

[0001] The present invention relates to a locking device for a container, comprising the features set forth in the preamble of claim 1 . [Background technology]

[0002] Vehicle chassis for accommodating 40-foot and 20-foot long containers are often designed as so-called "gooseneck chassis," with a lowered rear and a higher front. The longer 40-foot containers have a gooseneck tunnel that extends into the higher front of the chassis. When carrying two 20-foot containers, which usually do not have a gooseneck tunnel, instead of one 40-foot container, the 20-foot containers stand at different heights at the front and rear of the chassis.

[0003] Arrangements of multiple locking devices on either side of the front end to accommodate containers with and without a gooseneck tunnel are known from German utility model G 9114903.7, which have a bayonet pin that can be moved in a horizontal plane to hold containers with a gooseneck tunnel and a pivot pin that can be rotated on a vertical axis to hold containers with a different design.

[0004] German Patent Application Publication DE 19720238 A1 discloses a general prior art container locking device for the front end of a gooseneck chassis. This known container locking device has a housing in which a movably mounted bayonet pin and a rotatably mounted pivot pin are housed, with the bayonet pin and the pivot pin being geared together so that when the pivot pin is actuated, the bayonet pin moves accordingly and / or when the bayonet pin is actuated, the pivot pin rotates accordingly. This improves comfort and safety. Since only one trigger element acts on both locking elements, the risk of operating errors is reduced. However, a drawback has been demonstrated in that a person must be present near the container locking device and must operate each trigger element during the loading process. Summary of the Invention

[0005] The invention is therefore based on the object of providing a locking device for containers which is automatically activated by the loading process.

[0006] The object of the present invention is achieved by the features of claim 1. Activation of the container locking device thus occurs by semi-automatically approaching the container fitting and pushing in at least one detection bolt. A properly loaded container pushes the detection bolt into the housing, so that, solely due to the pretension of the spring element, the bayonet pin is pushed laterally out of the housing and / or the pivot pin projecting above the housing is rotated about its longitudinal axis.

[0007] "Pivot pin" means a bolt with a locking head formed at its upper end. The locking head engages with a container fitting from below and rotates 90 degrees to hold the container. The pivot pin is a single, integral element with no other moving parts, and rotates only in the circumferential direction. Preferably, the pivot pin passes completely through the housing and protrudes from both sides of the housing.

[0008] The bayonet pins are used to hold the container with gooseneck tunnel on the gooseneck chassis with the retaining container fittings on the container end faces. The container is lowered to approximately the same level as the vehicle chassis, then moved in the direction of vehicle drive until it contacts the housing of the container locking device, and only then is it lowered completely. The bayonet pins can then be pushed sideways into the container fittings. As a result, there is no risk of the container moving vertically. The bayonet pins move in a straight line.

[0009] Preferably, the housing includes six side walls and is fixedly secured to the vehicle chassis. The housing protects the movable parts of the locking device (particularly the trigger element) from scratches, dirt, etc., and houses the pivot pin and bayonet pin.

[0010] However, it is particularly preferred to provide a bayonet pin and a pivot pin which are kinematically coupled together, for example by means of interlocking coupling elements formed on the bayonet pin and the pivot pin, respectively.

[0011] Due to the force coupling between the bayonet pin and the pivot pin, it is possible to actuate the pin by providing only one spring element on either one of the bayonet pin or pivot pin or in any other suitable location, while the other pin moves with the former without a mating spring element, but does not operatively mate with the container fitting depending on the type of container being used.

[0012] Expediently, the at least one detection bolt is arranged to be movable relative to the housing. In a particularly advantageous embodiment, the at least one detection bolt is guided to be axially movable relative to the housing. In this way, a linearly acting movement component from the approaching container fitting is transferred to the housing and used to activate the spring element.

[0013] Preferably, the at least one detection bolt is a vertical detection bolt arranged axially parallel to the pivot pin. Such a vertical detection bolt may be inclined relative to the pivot pin to allow movement without jamming. The pivot pin interacts only with the container fitting approaching from above, and the vertical detection bolt activates a spring element in the direction of movement of the container fitting, causing the pivot pin to rotate about its vertical axis from the unlocked position to the locked position.

[0014] As an alternative to arranging the vertical detection bolt for longitudinal movement substantially parallel to the axis relative to the pivot pin, the vertical detection bolt may be arranged for rotation about a first axis of rotation such that when the vertical detection bolt is loaded by the vessel fitting, the vertical detection bolt rotates about the axis of rotation along a circular path.

[0015] Preferably, the first rotation axis is not aligned with the pivot pin but is arranged perpendicular to the axial direction of the pivot pin, i.e., the first rotation axis lies in a horizontal plane.

[0016] Advantageously, the vertical detection bolt and the pivot pin pass through a common upper housing wall, which is necessary so that the pivot pin fits into the container fitting from below. In the released position, the vertical detection bolt protrudes beyond the upper wall and is pushed inward by the container fitting until it is at most flush with the upper wall.

[0017] Advantageously, the vertical detection bolt is positioned to the side of the pivot pin with a gap therebetween. The container fitting, lowered onto the housing from above, has an opening in its bottom surface through which the pivot pin protrudes. The container fitting is prevented from being lifted off the locking head by rotation. However, the vertical detection bolt is actuated by the bottom surface of the container fitting and is positioned in an offset position so that even if the container is lowered incorrectly, it will never be below the opening for receiving the pivot pin and will always be in contact with the bottom surface of the container fitting.

[0018] As an alternative to or in addition to the vertical detection bolt, the at least one detection bolt may be a horizontal detection bolt that is axially parallel to the bayonet pin or in an inclined position that allows it to move without getting caught. The axial parallelism refers to the portion of the bayonet pin that protrudes from the housing and is pressed into an opening molded in the side of the container fitting. The horizontal detection bolt, which is also horizontally movable, identifies when the container fitting is closer to the horizontal direction.

[0019] In addition to being movable substantially longitudinally and axially relative to the bayonet, the horizontal detection bolt may be rotatable about a second axis of rotation such that when the horizontal detection bolt is loaded by a vessel fitting laterally adjacent to the horizontal detection bolt, the horizontal detection bolt rotates about the axis of rotation along a circular path.

[0020] Preferably, the second rotation axis is arranged perpendicular to the axial direction of the bayonet without needing to be aligned with the bayonet, i.e. the second rotation axis lies in a vertical plane.

[0021] It has proven particularly advantageous for the horizontal detection bolt and bayonet to pass through a common housing end wall, which is an end stop for the vessel fitting that is closer to the horizontal, allowing for early activation of the bayonet when the horizontal detection bolt is located within the end wall.

[0022] Preferably, the horizontal detection bolt is spaced aside from the bayonet pin. This will also reduce the probability of a failed bayonet activation, which may result from the horizontal detection bolt being too close to the bayonet pin and not abutting the side of the receptacle fitting, but instead protruding into the receptacle fitting's bayonet-receiving opening. "Spaced aside" refers to a position that is offset above, below, forward, or rearward from the bayonet pin when viewed from the side.

[0023] Advantageously, the trigger element includes a catch hook that abuts a surface of the vertical and / or horizontal detector bolt in the housing that is remote from the container fitting. In this way, a direct force transmission from the vertical or horizontal detector bolt to the catch hook is generated. The catch hook is releasably hooked onto a pivot pin or bayonet pin and preferably has a curved or angled portion. The catch hook is positioned relative to the housing such that the housing tilts due to a pressing action transmitted from the vertical or horizontal detector bolt, releasing the vertical or horizontal detector bolt pretensioned by the spring element.

[0024] In a particularly preferred embodiment, the pivot pin or bayonet pin is maintained in the release position by the capturing hook. To reach the locked position, the snug connection between the capturing hook and the pivot pin or bayonet pin is broken and one or both pins are moved into the locked position by the pretension of the spring element.

[0025] The pivot pin or bayonet may be formed with a catch element adapted to engage the catch hook from behind in the release position, and preferably the catch element includes at least one wall oriented substantially perpendicular to the direction of movement of the pivot pin or bayonet for engagement.

[0026] Advantageously, the pivot pin has a circular or inclined abutment surface on its side facing the catch hook of the catch element in the locked position, which abuts against the catch hook when returning from the locked position to the unlocked position and along which the catch hook slides until it reaches the unlocked position. In the unlocked position, the catch hook moves into a locking position that provides a tight connection, for example by engaging with the catch element from above, in particular by a curved or angled part of the catch hook contacting a wall perpendicular to the direction of movement of the catch element.

[0027] Desirably, when the vertical or horizontal detection bolt is forced into the housing by the receptacle fitting, the capture hook is released from operative engagement with the capture element and the spring element moves the bayonet pin and / or pivot pin to the locked position, which occurs automatically, i.e., without human intervention.

[0028] Advantageously, the pivot pin is non-rotatably engaged with an actuating lever which allows the pivot pin to be moved from the locked position to the unlocked position, i.e., the spring element to be moved to the pretensioned position. Preferably, the actuating lever projects radially from the pivot pin portion outside the housing. To move the pivot pin to the unlocked position after the automatic locking position, the actuating lever must be manually actuated by an operator.

[0029] Advantageously, the spring element is a torsion spring that is held fixed relative to the housing at a first extremity and connected to the pivot pin at a second extremity. The torsion spring may be designed, for example, as a helical or spiral spring and should provide sufficient return torque when the pivot pin is rotated approximately 90 degrees.

[0030] The torsion spring may be disposed around a particular portion of the coaxial pivot pin, most suitably the lower portion of the pivot pin that protrudes from the housing.

[0031] Advantageously, the torsion spring is at least partially arranged outside the housing. In the most advantageous embodiment, the torsion spring is completely arranged outside the housing. This housing design allows for very compact dimensions.

[0032] As an alternative to the torsion spring embodiment of the present invention, the spring element may be a compression spring that engages the bayonet at a first end and is immovably supported in the housing at a second end. This embodiment requires a somewhat larger housing, e.g., a housing that accommodates the compression spring in the form of a helical spring. The compression spring pushes the bayonet forward, and if there is a pivot pin forcibly coupled to it, the pivot pin will rotate from the unlocked position to the locked position.

[0033] Preferably, the first tip mates with the portion of the bayonet that is permanently housed within the housing, where the bayonet is well supported radially and the compression spring does not need to withstand lateral forces.

[0034] Advantageously, the compression spring is fully contained within the housing, thereby reducing contamination and improving the operational usability of the container locking device.

[0035] Advantageously, in the unlocked position, the bayonet passes through the housing and protrudes beyond the opposite end wall of the container fitting. In the locked position, the bayonet may be flush with the opposite end wall of the container fitting, or may protrude less or be recessed from the end wall than in the unlocked position. By virtue of this design, the bayonet can be used as an indicator of the unlocked and / or locked state.

[0036] For a better understanding, the invention will now be described in more detail with reference to the following figures. [Brief explanation of the drawings]

[Figure 11] FIG. 10 is a side view of a fifth embodiment of the present invention showing a rotatably arranged vertical and horizontal detection bolt. DETAILED DESCRIPTION OF THE INVENTION

[0038] 1 to 3 are side views showing the container fitting 6 and the container locking device approaching successively from above.

[0039] The container locking device comprises a box-shaped housing 1 having a top wall 10 and two end walls 11 disposed on the sides thereof. The housing 1 is closed by further side walls and a bottom wall, not shown.

[0040] Housing 1 is entirely traversed by pivot pin 3, the upper end 21 of which passes through top wall 10 and forms a mushroom-shaped locking head 22. When the container is lowered, locking head 22 protrudes into container fitting 6 from bottom surface 6a, and after rotating approximately 90 degrees, protects the container from being lifted. A lower end 23 of pivot pin 3 protrudes outward from the bottom of housing 1.

[0041] In the illustrated embodiment, in addition to the above-mentioned pivot pin 3, locking means in the form of bayonet pins 2 are provided, which are also used to handle containers with gooseneck tunnels if required. These containers are not lowered onto the container locking device from above via a container fitting 6, but are pushed in front of the container locking device from the side, the corresponding container fitting 6 having an opening to receive the bayonet pins 2. The loading process and the associated components of the container locking device will now be explained in more detail with reference to Figures 4 to 6.

[0042] 10, the pivot pin 3 has a gear portion 19 that is in constant engagement with a radially protruding rack portion 2b formed on the bayonet pin 2. Thus, the pivot pin 3 and the bayonet pin 2 form a gear mechanism and are forcibly coupled.

[0043] Due to the forced coupling between the pivot pin 3 and the bayonet pin 2, in the first embodiment according to Figures 1 to 7 it is sufficient to connect the spring element 4 to the pivot pin 3 or to the bayonet pin 2. If the spring element 4 and the pivot pin 3 interact, the spring element 4 may be designed as a torsion spring 16 which exerts its restoring force on the pivot pin 3. A first extremity 16a of the torsion spring 16 is fixedly or directly fixed to the housing 1, and a second opposite extremity 16b is fixed to the pivot pin 3 (see Figure 7). The torsion spring 16 exerts its restoring force particularly effectively if it is pressed coaxially onto the lower end 23 of the pivot pin 3.

[0044] A trigger element 5 including at least one detection bolt 7 and a capture hook 12 is disposed within the housing 1. The at least one detection bolt 7 must detect when the container fitting 6 approaches both vertically and horizontally, and therefore employs a vertical detection bolt 8 and a horizontal detection bolt 9. The vertical detection bolt 8 and the horizontal detection bolt 9 are each movably positioned within the housing 1 and protrude from the housing 1 through a plurality of corresponding perforations. In this case, the vertical detection bolt 8 penetrates the top wall 10, and the horizontal detection bolt 9 penetrates the adjacent end wall 11. Because the vertical detection bolt 8 protrudes beyond the top wall 10, the bottom surface 6a of the container fitting 6 abuts against the vertical detection bolt 8 when the container is lowered, and the vertical detection bolt 8 is pushed into the housing 1 until it is flush with the top wall 10 of the housing 1.

[0045] Because the horizontal detection bolt 9 protrudes from the end wall 11, the side surface 6b of the container fitting 6 abuts against the horizontal detection bolt 9 when containers are loaded from the side, and the horizontal detection bolt 9 is pushed into the housing 1 until it is flush with the end wall 11 of the housing 1.

[0046] A further important aspect of the present invention is the orientation of the vertical detection bolt 8 relative to the horizontal detection bolt 9, i.e., that their axes of motion x and z are aligned and lie in a vertical plane. In this way, when the vertical detection bolt 8 and the horizontal detection bolt 9 are pushed into the housing 1 by the container fitting 6, they can abut against the capturing hooks 12 within the housing 1.

[0047] The capturing hook 12 is housed in a rocker 24 in the housing 1 so as to be rotatable on a horizontal axis, and when a pushing force is exerted by the vertical detection bolt 8 or the horizontal detection bolt 9, it rotates upward.

[0048] In Figure 1, the container fitting 6 is still in a position where it is spaced from the vertical detection bolt 8, and the pivot pin 3 is in a release position where a rotational restoring force is acting on the pivot pin 3 from the torsion spring 16. The pivot pin 3 is provided with a capture element 13 that protrudes radially within the housing 1. The capture hook 12 of the trigger element 5 engages with the capture element 13 to prevent rotation in the direction of the spring force of the torsion spring 16. To this end, the capture hook 13 has a curved portion or corner 12a at one end that fits beyond the capture element 13. The capture element 13 has a vertical wall 13a where the corner 12a contacts the surface remote from the trigger element 5.

[0049] In Figure 2, the container fitting 6 has pressed the vertical detection bolt 8 into the housing 1 until it is almost flush with the top wall 10, but the container fitting 6 is still approximately 6 mm away from the top wall 10. The capturing hook 12 has already rotated upward at this point, initiating the locking process of the capturing element 13. In the illustrated embodiment, the vertical detection bolt 8 has tilted the capturing hook 12 about its horizontal axis of rotation, thus releasing the corner 12a from the vertical wall 13a, and the pivot pin 3 has been rotated to the locked position by the spring force of the torsion spring 16, as shown in Figure 3. Although there is no suitable container fitting 6 within its area of ​​action, the bayonet pin 2 is also in the locked position because it is kinematically coupled to the pivot pin 3.

[0050] When the container is fully loaded and the pivot pin 3 is in the locked position, as shown in Figure 3, the catch hook 13 has already switched to its home position, allowing the lock to be released even if a container is loaded or the detection bolt 7 has been activated. The catch hook 13 is only briefly lifted during the locking process and then returns to its home position, allowing the locking device to be opened later. The full length of the securely attached actuating lever 15, which rotates approximately 90 degrees with the pivot pin 3 relative to its position in Figure 1, is now visible at the lower end 23 of the pivot pin 3. To prevent unintentional release of the locked position during transport, a catch 18 is located on the end wall 11 nearest the end of the actuating lever 15. This catch 18 is pushed upward by the actuating lever 15 when it is rotated to the locked position and then retracts under gravity into its locked position. To rotate the actuating lever 15 back to the unlocked position of the pivot pin 3, the catch 18 must be manually lifted and the actuating lever 15 must pass under the catch 18.

[0051] In the illustrated embodiment, the actuating lever 15 is pressed into an auxiliary bore in the lower end 23 of the pivot pin 3 and is secured by a set screw 25 to prevent it from slipping out. The actuating lever 15 allows the pivot pin 3 to be rotated back to the release position before the container is lowered. During this rotation process, the capturing hook 12 is pushed up by the capturing element 13, which has an inclined or circular abutment surface 14 for lifting the capturing hook 12 so that the capturing element 13 can rotate and pass under the capturing hook 12 and position the capturing hook 12 on the capturing element 13 from above.

[0052] 4 to 7 show that the container fitting 6 of the gooseneck container is closer to the horizontal direction. To expand the contact surface, the horizontal detection bolt 9 is covered with a baffle plate 20. The baffle plate 20 is rotatably fixed to the end wall 11 of the housing 1 and loosely rests on the horizontal detection bolt 9.

[0053] 5, when the container fitting 6 is closer to the horizontal direction, the container fitting 6 first abuts the baffle plate 20, which then pushes the horizontal detection bolt 9 into the housing 1 and lifts the capture hook 12, breaking contact with the capture element 13. Therefore, the pivot pin 3, which is biased by the torsion spring 16 but is not engaged with the container fitting 6, rotates to the locking position, causing the rack portion 2b of the bayonet pin 2 to move via the gear portion 19 (see FIG. 10).

[0054] 8 shows a second embodiment of the invention, which comprises one detector bolt 7, a vertical detector bolt 8, which interacts only with the pivot pin 3. This embodiment is only suitable for vehicles carrying only standard containers without a gooseneck tunnel. Here, the horizontally movable bayonet pin 2 and the corresponding horizontal detector bolt 9 are not required.

[0055] 9 shows a third embodiment of the invention, specifically for locking containers with gooseneck tunnels, and therefore with a horizontal detection bolt 9 as the detection bolt 7, which interacts only with the bayonet pin 3. For this application, the vertically rotatable pivot pin 3 and the corresponding vertical detection bolt 8 are not required.

[0056] 10 shows a fourth embodiment of the invention, in which a compression spring 17 is used as the spring element 4 instead of the torsion spring 16. The compression spring 17 exerts pretension only in translational motion and is therefore connected to the bayonet pin 2 rather than the pivot pin 3. Preferably, the compression spring 17 is arranged coaxially on the bayonet pin portion 2a housed only in the housing 1, with a first end 17a engaging the bayonet pin 2 and an opposite second end 17b engaging the housing 1 (in particular the end wall 11). In this case, the entire compression spring 17 is always surrounded by the housing 1.

[0057] FIG. 11 shows a fifth embodiment of the invention in which, instead of the vertical and horizontal detection bolts 8 and 9 being longitudinally movable relative to the housing 1, the vertical and horizontal detection bolts 8 and 9 are rotatable.

[0058] The vertical detection bolt 8 is fixed like a hinge to the top wall 10 of the housing 1 by a first rotation axis y1, protrudes from the top wall 10 when the pivot pin 3 is in the released position, and rotates into the housing 1 when a load is applied from the container fitting 6. At this time, the vertical detection bolt 8 rotates u1 around the rotation axis y1. As the vertical detection bolt 8 rotates u1 into the housing 1, it releases the capturing hook 12 from the engagement position with the capturing element 13, and the pivot pin 3, pretensioned by the spring element 4, rotates from the released position shown in the figure to the locked position. The rotation axis y1 is located on the same plane as the top wall 10.

[0059] Similarly, when the container fitting 6 is approached from the side, the locking device activates the horizontal detection bolt 9 to rotate about a second rotation axis y2 relative to the end wall 11. The second rotation axis y2 allows the horizontal detection bolt 9 to rotate u2 into the housing 1, so that the capturing hook 12 releases the pivot pin 3. The second rotation axis y2 is located flush with the end wall 11 facing the container fitting 6.
