Definitions
- the invention relates to a pivot for a door, in particular a top pivot for a door, and a door closer system including the pivot.
- top pivots are known to be combined with floor-concealed door closers.
- Floor concealed door closers are provided in a recess of the floor with a top surface being on the same level as the floor.
- a spindle is the only part protruding from the top surface, wherein the spindle is provided to be connected to a bottom part of a door. As soon as the door is released after opening, the spindle pulls the door back to the closed state.
- FIG. 1 discloses a top pivot 100 having the design of a conventional first class lever mechanism.
- the effort is applied via a screw 500 along a first direction 600.
- the effort is applied to a rocker 300 on a first side of the fulcrum 400 such that the rocker 300 pushes a pivot pin 200, which is provided on a second side of the fulcrum 400, along the second direction 700.
- the second direction 700 is opposite to the first direction 600.
- the screw 500 is fastened up or down which in turn moves the pin accordingly.
- top pivot 100 requires a lot of space.
- a length dimension of the known top pivot is rather large due to the dimensions of the rocker arm.
- the object of the present invention is to provide a pivot of the species indicated in the generic part of patent claim 1, which can be manufactured at a low cost and which has a small overall size.
- the inventive pivot for a door is especially a top pivot and comprises a pivot pin, an adjusting element and a connecting element.
- the pivot pin has a center axis and is slidable along the center axis. Further, the pivot pin is engageable with the door. In case the pivot pin is engaged with the door, the pivot pin provides a pivot point of the door.
- the connecting element has a rotation center about which the connecting element is rotatable. Further, the connecting element has an arm portion. An end portion of the arm portion of the connecting element is connected with the pivot pin for coupling a displacement of the pivot pin and the connecting element. Additionally, the adjusting element is provided such that a force is providable to the arm portion between the rotation center and the end portion. Therefore, the pivot sets up a third class lever system.
- the pivot comprises a base element for supporting the pivot pin and the adjusting element.
- the base element has at least a first surface.
- the base element comprises a base plate which is covered by a cover plate.
- the surface of the cover plate not facing the base plate is regarded the first surface of the base element.
- the center axis of the pivot pin is perpendicular to the first surface.
- the pivot pin is slidable between a locking position and a retreat position. In the locking position the pivot pin protrudes more from the first surface of the base element than in the retreat position. In particular, the pivot pin does not protrude in the retreat position from the first surface. In the locking position, the pivot pin is engageable with the door.
- the connecting member comprises a first stopping member and a second stopping member.
- the first stopping member abuts against the base element when the pivot pin is in the retreat position. Additionally, it is preferred that the second stopping member abuts against the base element when the pivot pin is in the locking position.
- the adjusting element is preferably accessible for rotating from the first surface of the base element.
- the first surface is particularly the only surface which is accessible when the pivot is mounted in a door frame. Since the pivot is preferably a top pivot, the first surface is preferably a bottom surface of the pivot.
- the base element comprises a hollow protrusion in which the pivot pin is supported.
- the hollow protrusion is a cylindrical hollow protrusion.
- the hollow protrusion preferably comprises a slit, in which the connecting element, especially the arm portion of the connecting element, can be moved without interfering with the base element.
- the hollow protrusion allows only a movement of the pivot pin along the center axis.
- the adjusting element comprises a flange portion.
- the flange portion is provided in a recess of the connecting element. Therefore, the adjusting element and the connecting element are joined in a form locking manner. As a result, any movement of the connecting element is only possible with simultaneous movement of the adjusting element.
- the adjusting element comprises a first threat, in particular an external threat, which is engaged with a second threat provided in the base element.
- the second threat particularly is an internal threat.
- the adjusting element is an adjusting screw such that the adjusting screw is displaced in relation to the base element when the adjusting screw is rotated.
- the adjusting element is preferably provided in parallel to the center axis of the pivot pin. Therefore, a rotation of the adjusting element with respect to the connecting element leads to a displacement of the connecting element in parallel to the center axis. Accordingly, the direction of displacement of the connecting element is parallel to the only possible displacement directions of the pivot pin. Hence, the coupling of the movement of the pivot pin and the connecting element can be reached rather simple.
- the pivot pin comprises a hole. Further, an end portion of the connecting element is provided within the hole.
- the connecting element preferably has an arm portion, while an end portion of the arm portion is provided within the hole.
- the hole is a through hole.
- the invention also relates to a door closer system.
- the door closer system comprises a floor-concealed door closer and a pivot as described above.
- the inventive door closer system therefore is advantageous with respect to available space, in which the door closer system shall be installed.
- FIG. 2 is an exploded view of the inventive pivot 1 according to a preferred embodiment.
- Figure 3 is a sectional view of the pivot 1 shown in figure 1 .
- the pivot 1 comprises a base element 9 having a base plate 10 and a cover plate 11.
- the cover plate 11 covers the base plate 10.
- the base element 9 comprises a first surface 13 which is the surface of the cover plate 11 not facing the base plate 10.
- the base element may 9 be attached to a door frame, in particular to a top portion of the door frame, such that the first surface 13 is a bottom surface.
- the first surface 13 comprises two holes, one for a pivot pin 2 and another for an adjusting element 4.
- the adjusting element 4 is therefore accessible for rotating from the first surface 13, wherein a rotation of the adjusting element 4 causes a displacement of the pivot pin 2. Due to the displacement, a length of the pivot pin 2 protruding from the first surface 13 can be adjusted.
- the pivot pin 2 has a cylindrical shape and comprises a center axis 3.
- the above described displacement of the pivot pin 2 can only performed along said center axis 3.
- the pivot pin 2 is supported within a hollow protrusion 12.
- the hollow protrusion 12 is provided on the base plate 2 on the opposite side of the surface facing the cover plate 11.
- an axis of a inner cylindrical shape of the hollow protrusion 12 is identical to the center axis 3 of the pivot pin 2.
- the hollow protrusion 12 as well as the center axis 3 of the pivot pin 2 is orientated perpendicular to the first surface.
- the adjusting element 4 is also provided perpendicular to the first surface 13.
- the pivot pin 2 is provided slidable within the hollow protrusion 12. A movement of the pivot pin 2 is caused by the adjusting element 4 and transferred to the pivot pin 2 by a connecting element 5.
- the pivot pin 2 and the connecting element 5 are coupled as follows:
- a third class lever system is set up by the connecting element 5.
- the connecting element 5 comprises a rotation center 7, which is formed as a hole. Said hole is penetrated by a bolt 20 which joins the connecting element 5 and the base element 9. Since the connecting element 5 comprises an arm portion 6 being connected to the pivot pin 2, a rotation of the connecting element 5 about the rotation center 7 causes the pivot pin 2 to slide along the center axis 3 within the hollow protrusion 12.
- the adjusting element 4 is formed as an adjusting screw which is screwed into the base plate 10.
- the adjusting element 4 can be rotated with respect to the base element 9 such that the adjusting element 4 is screwed in or screwed out the base element 9.
- the displacement caused when rotation the adjusting element 4 is transferred to the connecting element 5.
- the adjusting element 4 is provided between the rotation center 7 and the end portion 15 of the connecting element 5. In this way, said third class lever system is created.
- FIGS 3 and 4 show the details of the movement of the pivot pin 2 in figures 3 and 4.
- Figure 3 shows the pivot pin 2 in a retreat position while figure 4 shows the pivot pin 2 in a locking position.
- the adjusting element 4 comprises a flange portion 8.
- the flange portion 8 is provided within a recess 19 of the connecting element 5 for a form locking joint. Therefore, the rotation of the connecting element 5 about the rotation center 7 is connected to a displacement of the adjusting element 4 which is connected rotation of the adjusting element 4.
- Figure 3 shows the pivot 1 with the pivot pin 2 in the retreat position.
- a first stopping member 16 of the connecting element 5 abuts against the base element 9, in particular against the base plate 10. Therefore, a further rotational movement of the connecting element 5 about the rotation center 7 is blocked.
- the pivot pin 2 maintains in the retreat position until the adjusting element 4 is rotated.
