Description

The invention relates to a connecting element for establishing a releasable, positive connection between two or more components.

For releasably connecting two or more components, each having a bore, usually threaded bolts are used. Also known are movable thrust bolts, which are retracted starting from a component in corresponding openings of the opposite component. Disadvantageously, a frictional connection is established by the retraction of such thrust bolts only in the transverse direction to the direction of movement of the thrust bolt.

The use of such thrust bolts, for example for sectional doors is off DE 100 37 329 A1 known. It is a Sektionalfalttor, in which an escape door is embedded without threshold. To anchor the likewise foldable door sections with the adjacent door sections, at least starting from the lowermost door section, push bolts are inserted into corresponding openings of the door sections. Disadvantageously, the door sections interrupted by the door sections remain longitudinally impaired in their stability. The lack of a positive connection in all directions is generally present when two components are connected by shear pins of the type described above.

However, all have in common that in the non-activated state, the clamping piece for connecting the components is not retracted in a Hüllstück / component. In the deactivated state, there is no common plane of the bolt, clamping piece and Hüllstückes.

Furthermore, the clamping piece is displaced together with the bolt in the second component until the clamping piece is stopped by a stop, after which the bolt is further extended and jamming between the first and the second component is ensured, due to the action of the locking balls.

The object is against this background in the construction of a connecting element that produces a positive connection in all directions between two or more components or objects. In this case, the releasable connection should be produced by moving individual parts of the connecting element.

To solve the problem, the invention teaches a connecting element, which is characterized in that

• - a bolt ( 1 ) together with a the outside of the bolt ( 1 ) surrounding clamping piece ( 3 ) and one the outside of the clamping piece ( 3 ) surrounding envelope ( 5 ) forms a telescopic unit, wherein
• - the envelope ( 5 ) on the outside with a first component ( 9 ), and
• - the bolt ( 1 ) as well as the clamping piece ( 3 ) telescopically in the in a second component ( 10 ) provided opening ( 7 ) are retractable, and that
• - in the wall of the clamping piece ( 3 ) for receiving movable security elements ( 8th ) in the radial direction pointing and the wall sweeping openings ( 4a ) are provided, and
• After locking the movement of the clamping piece ( 3 ) within the second component ( 10 ) due to the continued movement of the bolt ( 1 ) the security elements ( 8th ) in the radial direction through the openings ( 4a ) until its positive intervention in corresponding recesses ( 2a ) in the second component ( 10 ) are movable.

In contrast to the known and integrally constructed thrust bolts of the bolt of the connecting element according to the invention forms together with a clamping piece surrounding the bolt and an applied on the outside of the clamping piece Hüllstücks a telescopically constructed unit. The connecting element is connected via the outside of the Hüllstücks with one of the components to be connected. The positive and non-positive connection is established after the bolt is retracted together with a part of the clamping piece in the second component and engage under the influence of the continued bolt movement in the radial direction movable securing elements in the corresponding recesses of the second component.

The core idea of the invention is that the movement of the securing elements movable in the radial direction is controlled by correspondingly shaped depressions on the lateral surface of the bolt. The displacement of the additional securing elements in the radial direction begins after the clamping piece has been retracted together with the bolt in the second component and locked there under the continued movement of the bolt.

In a preferred embodiment of the invention, one or more axially aligned recesses are provided on the lateral surface of the bolt in that section which comes to lie on the inside of the second component and is surrounded by the clamping piece. The recesses are ramped, with the flat rising side facing in the direction of the component from which the bolt moves away during assembly of the connection. After locking the clamping piece in the region of the second component, the bolt moves further in the direction of the second component, wherein the additional securing elements increasingly displaced by the ramp-like recesses in the radial outward direction through the openings of the clamping piece in corresponding recesses on the inside of the second component become. In principle, it is also conceivable that the moving together with the clamping piece in the second component bolt is moved in accordance with adapted shaping of the lateral surface of the bolt for displacing the securing elements in the radial direction after retraction of the clamping piece in the second component in the opposite direction. After completion of the movement of the bolt, the securing elements are under the pressure of the expanding bolt in corresponding complementary shaped recesses on the inside of the second component. When the bolt is withdrawn, the openings in the wall of the clamping piece pointing in the radial direction lie above the securing elements located in the recesses of the bolts. When the bolt is extended, the openings pointing in the radial direction in the wall of the clamping piece lie at the same height with correspondingly complementarily shaped depressions on the inside of the opening in the second component.

In a development of the invention, it is provided that the movement of the bolt in the direction of the second component is limited by a stop arranged within the first component. The stop should be movable, d. H. be adjustable, wherein the setting of the stopper is to be made so that the widening in the region of the ramp-like depressions bolt the locking elements displaced as much as possible in the corresponding recesses provided in the second component. During the construction of a positive connection between securing elements and the second component, the tensile force acting on the bolt increases at the same time, since the other end of the bolt is locked by the stop. As a result, the first component is "pulled" in the direction of the second component, which improves the connection between the components.

The pulling effect described by the aforementioned embodiment can be enhanced if the bolt also has one or more axially aligned recesses in the portion which remains in the first component after connection of the components. Even with these depressions, the side directed towards the middle of the first component increases in a ramp-like manner. In the retracted state of the bolt, the openings pointing in the radial direction of the clamping piece also come to rest above these depressions. After introduction of the clamping piece together with the bolt in the second component, the end face of the clamping piece abuts against a corresponding edge in the second component and is arrested in this way, while the bolt can move on due to the telescopic structure, Be by the bolt movement, the securing elements in the Area of the first component displaced in the radial direction in the openings in the clamping piece to the outside and pressed into the corresponding complementary shaped recesses on the inside of the component.

The movement of the clamping piece in the direction of the second component is limited by a frontally positioned stop. The stop may consist of a lying in the opening of the second component circumferential edge. Alternatively or additionally, it is conceivable that the movement of the clamping piece and / or the bolt is locked by a provided on the inside of the Hüllstücks stop.

It is envisaged that the hollow-cylindrical clamping piece has a bevelled outer edge on its end face oriented towards the second component. The bevelled outer edge facilitates the insertion of the clamping piece together with the bolt in the second component and prevents insertion of the clamping piece is completely prevented with a slight offset between the first and the second component. However, the chamfer of the front side must be such that the clamping piece is effectively locked after introduction into the second component despite the bevel. It is also conceivable that the serving for locking edge is formed in the second component complementary to the frontal bevel of the clamping piece.

It is envisaged that used as securing elements balls or cylindrical pins become. The balls have the advantage that their friction is low and they can adjust due to the rotatability of the changed balance of power in forward and backward movement of the bolt. In principle, however, bolts can also be used as securing elements. To produce a connection that is as positive as possible, at least the end faces pointing in the radial direction are shaped as a hemisphere. However, in order to reduce the friction generated by the inclusion of the bolt moving further after the clamping piece has been locked, it is advantageous if the inner end face of the securing bolt is also rounded or if it has a shape adapted to the ramp-like rising mantle surface of the bolt.

Due to the spherical shape of the securing elements, the securing elements generate a tensile force with increasing displacement of the balls, which increases until the securing elements abut with their front side positively at the lowest point in the corresponding recesses on the inside of the two components.

The mechanism for connecting the two components under the influence of the moving bolt also depends on the fact that the diameter of the balls is dimensioned so that the balls protrude with retracted bolt over the lateral surface of the bolt, but not over the lateral surface of the clamping piece. This ensures that the bolt entrains the clamping piece during its return movement, d. H. with retracts into the first component. This happens because the securing elements protrude beyond the lateral surface of the bolt when they rest at the lowest point of the ramp-like recesses and thus slightly protruding beyond the lateral surface securing element thus serves as a driver in the return movement of the bolt in the direction of the first component.

It is within the scope of the invention that the recesses for receiving the securing elements on the inside of the second component are not limited to the hemispherical shape, but are designed as a circumferential groove-like depression. When using balls as security elements, it is advisable that on the inside of the components a circumferential, semi-circular in cross-section groove is attached. In a circumferential groove or in the azimuthal direction extended recesses advantageously the rotatability of the parts can be ensured transversely to the bolt. This rotation can be advantageous in the use of the connecting element in Sektionalfalttoren with escape door.

It is within the scope of the invention that the bolt has a circular or a polygonal cross section. The shape of the clamping piece is adapted at least in the region of the inner opening to the outer shape of the bolt. The same applies to the Hüllstück, which is a hollow profile as well as the clamping piece due to the telescopic structure.

The wall thickness of the clamping piece must be less than the diameter of the balls. Only thereby it is possible that the balls protrude with extended bolt over the lateral surface of the Hüllstücks. In a preferred embodiment of the connecting element, the wall of the clamping piece has at least one axially aligned slot. In this slot engages a driver, which is connected for example in the form of a threaded screw in the radial direction with the bolt. In this case, the length of the slot corresponds approximately to that distance by which the fully extended bolt projects beyond the clamping piece likewise introduced into the second component.

The recesses on the lateral surface of the bolt may have the same or a different distance from the tip of the bolt. If the recesses have a different distance from the tip of the bolt, the attachment of the lying on the inside of the components recesses designed in the context of manufacturing accordingly more complex. If the recesses on the lateral surface of the bolt all have the same distance from the tip of the bolt, the recesses can be mounted on the inside of the component with the advantage of ease of manufacture as a circumferential groove.

For the symmetrical distribution of the forces that build up with the radial movement of the securing elements, it is provided that the depressions on the lateral surface of the bolt are distributed equidistantly on the outer circumference of the bolt.

It is conceivable that the Hüllstück for easier replacement of the connecting element is detachably connected to the first component. To produce a releasable connection, the Hüllstück could, for example, on the outside have a thread that is complementary to a cut into the component thread. The connecting element according to the invention can also be installed in pairs next to or above one another. To facilitate installation, the connecting elements are completely or partially surrounded by frame-like elements in a paired arrangement, wherein the frame-like elements are adapter-like connected to the first component.

Of course, it is within the scope of the invention that with a corresponding length of the bolt and the clamping piece surrounding the bolt, more than two components can be connected. It is also possible that to build a non-positive connection between all components to be connected on the inside of each component rest in the radial direction movable securing elements in correspondingly shaped recesses. The frame-like elements abut against the corresponding component as flat as possible, so that a connection which is as stable as possible is possible between the connecting element and the component. This applies in particular if the component is the door section of an escape door set in a sectional door. The door sections, which are often constructed of thin-walled aluminum sheet metal, can be connected to the connecting element or the Hüllstück over the larger area adjacent to the door sections frame elements over a larger number of point-shaped connections, such as rivets.

For the movement of the bolt different mechanical drives come into question. Particularly suitable are pneumatic and hydraulic drives or electric drives such as spindle motors.

The connecting element according to the invention is suitable for use as a locking element for doors for producing a positive connection between the door leaf and the door frame. This also includes the installation of the connecting element in a door lock.

The connecting element is also intended for use in connection with a sectional folding door with escape door. The frictional connection between the door section as the first component and the respectively adjacent door section as a second component is particularly important in sectional folding doors, whose bottom door section extends to the floor in the closed state of the door. The lack of a door sill in the area of the escape door is responsible for the fact that the door sections in the area of the escape door are severely destabilized. This especially affects the opening of the gate. The use of the connecting element according to the invention compensates for this weak point.

The installation of the connecting element should be such that, when the escape door is open, the end faces of the telescopically guided unit of Hüllstück, clamping piece and bolt on the narrow side of the door section lie in a single plane.

The connection element is suitable for adaptation to the openings provided in the corner areas of ocean-going containers for securing and for transporting these ocean-going containers. The devices belonging to the lifting device of loading cranes engage in the openings in the corners of the ocean-going containers. The openings located on the underside at the corners serve in turn for locking the high-sea container during transport on a truck or a railroad car. With the help of the connecting element according to the invention, a frictional connection can be created between the corresponding devices and the deep sea container, the advantage of which is that with increasing engagement of the movable elements in the radial direction a positive and in particular play-free connection is established. The advantage that the security elements build a play-free connection due to their rounded outer shape and with increasing intervention in the corresponding recesses also creates a pulling action on the bolt, can be used under safety aspects with particular advantage when stacking ocean containers on ships. The play-free anchoring of the high seas container is of particular importance in heavy seas.

Due to the positive engagement of standing when using the connecting element between two components connection, the connecting element is also suitable for producing a detachable connection between two components, of which at least one rotates. The use of the connecting element in mechanical engineering, for example in lathes, or in drilling and grinding machines is therefore of particular importance.

In the following, further details and features of the invention will be explained in more detail by means of examples. However, the examples shown are not intended to limit the invention, but only to explain. In a schematic representation:
