  • the plug-in section 13 has a Guide link 28, the holding contour 16 being displaceable in the guide link 28 between a first and a second end stop 29a, b.
  • the receiving opening 27 is introduced into the plug-in section 13 at the location of the first end stop 29a, the holding contour 29a being able to be elastically deformed through the receiving opening 27 at the location of the first end stop 29a, so that the snap element 15 can be mounted or dismantled.
  • the snap device 14 has a spring element 30 designed as a helical compression spring, which is arranged in the guide channel 16.
  • the spring element 30 applies a spring force to the snap element 15 in a first displacement direction VR1, so that the snap element 15 protrudes from the guide channel 16 with the end contour 18 and rests on the first end stop 29a via the holding contour 16.
  • the spring element 30 is supported in the first displacement direction VR1 on the snap element 15 and in a second displacement direction VR2 that is opposite to the first displacement direction VR1 on the plug-in section 13.
  • the plug-in section 13 has a pin aligned in the first displacement direction VR1 and to form a second spring seat 31b, the snap element 15 has a pin aligned in the second displacement direction VR2, the spring element 30 being plugged onto each end of the two pins .
  • the second inclined surface 24b is formed by a wedge-shaped indentation of the plug-in section 13 in a transition area to the contact section 9. This means that a second snap element can be dispensed with, so that the quick-assembly hinge 1 can be designed to be much simpler.
  • the quick-assembly hinge 1 can be assembled particularly easily and inexpensively, with a particularly robust design of the quick-assembly hinge 1 being implemented by forming the second inclined surface 21 on the plug-in section.
  • the plug-in section 13 When assembling the first hinge component 2, the plug-in section 13 is inserted in the plug-in direction SR through the opening 24, in which case the Snap element 15 slides with the introduction surface 20 on an edge of the opening 24.
  • the snap element 15 is displaced in the second displacement direction VR2 into the guide channel 16 against the spring force.
  • the plug-in section 13 is pushed into the opening until the first contact section 9 rests with its first contact surface 10 on the first mounting wall 22.
  • the snap element 15 snaps out in the first displacement direction VR1, so that the snap element 15 is supported with its first inclined surface 19 on a first edge 24a of the opening 24.
  • the plug-in section 13 is suspended in the second displacement direction VR2 between the first contact surface 10 and the second inclined surface 21, the second inclined surface 21 being supported on a second edge 24b opposite the first edge 24a.
  • the plug-in section 13 is thus held in the opening 24 in a form-fitting and non-positive manner.
  • the snap element 15 When dismantling, the snap element 15 must be pushed back in the second displacement direction VR2, so that the plug-in section 13 can be unhooked in the first displacement direction VR1 and removed from the opening 24 in the opposite direction to the plug-in direction SR.
  • Figures 5a, b each show the quick-assembly hinge 1 in a sectional view, where Figure 5a the quick-assembly hinge 1 in a longitudinal section along the pivot axis SA and Figure 5b represents the quick-assembly hinge 1 in a cross section.
  • the middle section 5c of the hinge pin 5 has a locking receptacle 32, which serves to accommodate a locking element 33.
  • the locking receptacle 32 is inserted laterally into the hinge pin 5, the locking element 33 being arranged within a receiving space 34 spatially connected to the guide section 6 and being displaceable in the receiving space 34 relative to the locking receptacle 32.
  • the locking element 33 is subjected to a spring force in the direction of the locking receptacle 32 by a spring device 35, which is formed by two compression springs.
  • the locking receptacle 32 is designed as a recess, which in an axial direction and an axial opposite direction with respect to the pivot axis SA is provided by an oblique contact surface 36a, b is limited.
  • the hinge pin 5 is inserted through the through hole of the first receiving section 7 and then through the guide section 6 into the blind hole of the second receiving section 8. If the hinge pin 5 is fully inserted, the locking element 33 automatically snaps into the locking receptacle 32, so that the hinge pin 5 is secured against being lost.
  • the second end section 5b of the hinge pin 4 has a non-round contour, with the second receiving section 5b having a corresponding counter contour, so that the hinge pin 5 is secured against twisting.
  • the contour of the second end section 5b is formed by a flattening.
  • the hinge pin 4 is removed from the two receiving sections 7, 8 and the guide section 6, with the locking element 33 sliding along the first contact surface 36a and being pressed back into the receiving space 34 against the spring force applied by the spring device 35.
  • the hinge pin 5 is thus released and can be completely removed.
  • the plug-in section 13 has a guide contour 37 for guiding the snap element 15 in the guide channel 16.
  • the snap element 15 has a guide counter-contour 18, wherein the guide contour 37 and the guide counter-contour 38 extend in the displacement direction VR and are in engagement with one another, so that the snap element 15 is guided straight in the displacement direction VR.
  • the guide contour 37 is formed by two opposing webs which extend into the guide channel 16.
  • the guide counter contour 38 is formed by two grooves that are complementary to the two webs and are introduced into the snap element 15 laterally opposite the associated web.
  • the Figures 6a, b show an alternative embodiment of the quick-assembly hinge 1 as a further exemplary embodiment of the invention.
  • the Figure 6a shows the quick-assembly hinge 1 in a perspective view, with the second hinge component 3 instead of the two threaded pin sections 17a, b Plug-in section 39 and a further snap device 40.
  • the further plug-in section 39 and the further snap device 40 are designed to be identical to the plug-in section 13 or the snap device 14 of the first hinge component 2, with the two plug-in sections 13, 39 being aligned in opposite directions in the displacement direction VR.
  • the Figure 6b shows the quick-assembly hinge 1 in an installation situation, wherein the quick-assembly hinge 1 is fixed with the first hinge component 2 on the first mounting wall 22 and with the second hinge component 3 on the second mounting wall 23.
  • the second mounting wall 22 has instead of the two through openings 25a, b, as in Figure 3 shown, a second breakthrough 41.
  • the quick-assembly hinge 1 is inserted in the insertion direction SR with the first insertion section 13 through the first opening 24 and with the second insertion section 39 through the second opening 41 and fixed in the respective opening 24, 41 by the respective associated snap device 14, 40.
