Abstract
Description
- The invention relates to a door closer arrangement. Specifically, the invention relates to a door closer arrangement, in which the door closer is a so-called cam door closer.
- Door closers having a cam are called cam door closers. In these door closers, the rotational axis is provided with a cam. The cam influences how the torque directed onto the door brings about loading of the spring in the door closer as the door is opened and how the force of the loaded spring is guided back onto the door when it closes.
- Door closers are manufactured to different closing moments for different kinds of doors. A larger and heavier door requires more torque to close the door than a lighter and smaller door. In order that the production costs should remain reasonable, it is also common to use the same door closer in two different torque classes. For example, in class EN4 (closing torque of over 26 Nm) and in class EN3 (closing torque of under 26 Nm) are often used the same door closer, because otherwise production costs would rise. It depends on the installation, to which class the door closer is seen as belonging. The installation site of the closer in relation to the hinge line of the door affects to which class the installed door closer belongs. For example, a door closer that is relatively close to the hinge line of the door is included in class EN3 and a door closer that is further away from the hinge line of the door is included in class EN4. However, installation of a door closer requires care and takes a relatively long time.
- The object of the invention is to decrease the disadvantages of known art. The invention is based on the idea that the installation position of the pulling arm of the door closer arrangement in relation to the door closer can be selected easily and reliably, wherein also the torque class of the door closer arrangement is selected. The door closer can always be installed at the same site in relation to the hinge line regardless of which torque class was selected. This considerably simplifies and expedites installation.
- In the invention, the pulling arm connectable to the rotational axis of the door closer comprises a hole, the surface/edge of which comprises the sector area of the pulling arm, and the outer surface/edge of the rotational axis of the door closer comprises the sector area of the rotational axis. The pulling arm is installed to the rotational axis such that the rotational axis, specifically its other end, is inside the hole, and, additionally, the sector area of the pulling arm is against the sector area of the rotational axis.
- A door closer arrangement according to the invention comprises a door closer 1 having a
rotational axis 2 and acam 4 in connection with the rotational axis. The door closer arrangement also comprises apulling arm 3, thefirst end 3A of which is connectable to therotational axis 2. Thefirst end 3A of thepulling arm 3 has ahole 3C, theedge 3D of which comprises toothing composed ofteeth 8 pointing towards the centre point of thehole 3C. Theedge 2A of therotational axis 2 comprisescounter-toothing comprising teeth 5 pointing away from the centre point of therotational axis 2. - The sector area of the pulling arm is to be placed against the sector area of the rotational axis, for example, in the following manner. The
edge 3D of the hole also comprises a sector 9 without toothing, and the counter-toothing also comprises one tooth 7, which is wider than theother teeth 5 of theedge 2A of the rotational axis. The pullingarm 3 is arranged to be connected to therotational axis 2 such that the tooth 7, which is wider than theother teeth 5 of theedge 3D of the hole of the counter-toothing of therotational axis 2, is in the area of said sector 9 of theedge 3D of the hole of thepulling arm 3. - The sector area of the pulling arm is to be placed against the sector area of the rotational axis also in the following manner. The
edge 3D of the hole also comprises onetooth 70, which is wider than theother teeth 8 of theedge 3D of the hole, and the counter-toothing also comprises asector 90 without toothing. The pullingarm 3 is arranged to be connected to therotational axis 2 such that thetooth 70, which is wider than theother teeth 8 of theedge 3D of the hole of the pulling arm, is in the area of saidsector 90 of the counter-toothing of therotational axis 2. - In the following, the invention is described in more detail by means of the accompanying figures, in which

Fig. 1 shows an example of a door closer arrangement according to the invention comprising a door closer 1 having arotational axis 2. The rotational axis also has acam 4 inside the door closer, which is by way of example shown inFigs. 2 and4 . The door closer arrangement also comprises apulling arm 3, thefirst end 3A of which is to be connected to therotational axis 2. Thefirst end 3A of thepulling arm 3 has ahole 3C, which is more clearly seen inFig. 3 . Theedge 3D of the hole comprises toothing composed ofteeth 8 pointing towards the centre point ofhole 3C. Theedge 2A of therotational axis 2 comprisescounter-toothing comprising teeth 5 pointing away from the centre point of therotational axis 2. - The
edge 3D of thehole 3C of the pulling arm also comprises a sector area 9 (70 inFig. 4 ) of the pulling arm, and theedge 2A of the rotational axis of the door closer comprises a sector area 7 (90 inFig. 4 ) of the rotational axis. The pulling arm is installed to the rotational axis such that therotational axis 2, specifically its other end, is inside thehole 3C, and, additionally, the sector area of the pulling arm is against the sector area of the rotational axis. The surfaces of the sector areas can be against each other in only four different positions, i.e. thepulling arm 3 is to be installed to the rotational axis in four different positions. In this case, the pulling arm is therefore in one possible (of four possibilities) position in relation to the door closer 1.Fig. 1 illustrates the possible positions. - As can be observed, the positions are symmetrical in relation to the longitudinal axis X of the door closer, wherein the pulling
arm 3 can be in two different positions on each side of the door. At the smaller angle B in relation to the longitudinal axis X of the door closer, a larger torque is achieved for closing the door, and, at a larger angle A in relation to the longitudinal axis X of the door closer, a smaller torque is achieved for closing the door. FromFigs. 2 and4 can also be seen, how the cam in connection with therotational axis 2 is in its basic position (door closer not loaded) in the same line with the longitudinal axis X of the door closer. - Using a smaller angle B, a larger torque class (for example, EN4) and, using a larger angle, a smaller torque class (for example, EN3) is achieved. This is feasible when toothing and counter-toothing are carried out such that the angle difference between two side-by-side positions of the pulling
arm 3 is approximately 8 - 12 degrees. - In some exemplary implementations, the angle difference is approximately 11 - 12 degrees. The sector of the
tooth 8 of the toothing of the pulling arm is therefore approximately 11 - 12 degrees as viewed from the centre point of thehole 3C, and the sector of thetooth 5 of the counter-toothing of theedge 2A of therotational axis 2 is approximately 11-12 degrees as viewed from the centre point of the rotational axis. - The tooth 7, which is wider than the
other teeth 5 of the counter-toothing of the embodiment ofFig. 2 , is in the 22 - 24 degrees sector as viewed from the centre point of the rotational axis. The area of the sector 9 of theedge 3D of the hole of the pullingarm 3 is 55 - 60 degrees. Correspondingly, in the second embodiment ofFig. 4 , thetooth 70, which is wider than theother teeth 8 of theedge 3D of the hole of the pulling arm, is in the 22 - 24 degrees sector as viewed from the centre point of the rotational axis, and the area of thesector 90 of theedge 2A of the rotational axis is 55 - 60 degrees. - The way of placing the sector area of the pulling
arm 3 against the sector area of therotational axis 2 is feasible, for example, in the manner shown inFig. 2 . In the example ofFig. 2 , theedge 3D of the hole of the pulling arm comprises a sector 9 without toothing, and the counter-toothing of therotational axis 2 comprises one tooth 7, which is wider than theother teeth 5 of theedge 2A of the rotational axis. The tooth, which is wider than the other teeth of the rotational axis, therefore forms the sector area of the rotational axis. - The pulling
arm 3 is arranged to be connected to therotational axis 2 such that the tooth 7, which is wider than theother teeth 5 of theedge 3D of the hole of the counter-toothing of therotational axis 2, is in the area of said sector 9 of theedge 3D of the hole of the pullingarm 3, wherein above said four different positions of the pulling arm are therefore made possible. The tooth 7, which is wider than theother teeth 5 of the counter-toothing, is therefore arranged to be placed at four different sites in the area of the sector 9 of theedge 3D of the hole of the pulling arm.Fig. 3 illustrates thehole 3C of the pullingarm 3, itsteeth 8 and sector 9. -
Fig. 4 shows another example of a second possible embodiment, of how the sector area of the pulling arm is to be placed against the sector area of the rotational axis. In this embodiment, theedge 3D of the hole of the pulling arm also comprises onetooth 70, which is wider than theother teeth 8 of theedge 3D of the hole, and the counter-toothing of therotational axis 2 also comprises asector 90 without toothing. The pullingarm 3 is arranged to be connected to therotational axis 2 such that thetooth 70, which is wider than theother teeth 8 of theedge 3D of the hole of the pulling arm, is in the area of saidsector 90 of the counter-toothing of therotational axis 2. As can be observed, thetooth 70, which is wider than theother teeth 8 of theedge 3D of the hole, is arranged to be placed at four different sites in the area of thesector 90 of the counter-toothing of therotational axis 2. - In the embodiments according to the invention, the
teeth 8 of the toothing of the pulling arm and theteeth 5 of the counter-toothing of theedge 2A of therotational axis 2 are arranged to settle interlaced against each other. In the embodiment ofFig. 2 is seen, how the sector 9 of theedge 3D of the hole of the pulling arm hasfree space 6 between theteeth 5 of therotational axis 2. This enables that the pulling arm has above said four installation positions. Correspondingly, from the embodiment ofFig. 4 is seen that there isfree space 61 between theteeth 8 of thehole 3C of the pulling arm to be placed to the area of thetoothless sector 90 of therotational axis 2, which also enables said four installation positions. -
Fig. 5 shows an installation example, in which the door closer arrangement also comprises aslide rail 10, which is to be connected to the pulling arm from itsother end 3B. In this example, thedoor closer 1 is installed to thedoor 11 and theslide rail 10 to theframe 12 of the door. It is also possible that thedoor closer 1 is installed to the frame of the door and the slide rail to the door. The pullingarm 3 slides from its other end in the direction X1 of theslide rail 10 as the door is opened and as the door is closed. - The installation position of the pulling
arm 3 in relation to thedoor closer 1 can be selected easily and reliably, wherein the torque class of the door closer arrangement is also selected. Thedoor closer 1 can always be installed at the same site in relation to the hinge line regardless of which torque class was selected. The hinge line is a vertical line formed by thehinges 13 of the door, in relation to which the door is to be rotated. The invention considerably simplifies and expedites installation. The installer does not need to estimate, remember and decide, to which site (to the door or to the frame) the door closer is installed. - In the invention, the sector area of the pulling arm and the sector area of the rotational axis are therefore to be installed against each other such that the installation options of the pulling arm are limited. The features of these sector areas deviate therefore from the toothing of the edge of the pulling arm and the counter-toothing of the edge of the rotational axis. Installation of the pulling arm to the rotational axis is not possible if these sector areas are not against each other.
- In the invention, the pulling arm is therefore arranged to be installed to the rotational axis of the cam door closer such that the pulling arm is either at a smaller angle or at a larger angle in relation to the longitudinal axis of the door closer and on either side of the door closer as viewed from its longitudinal axis. In this case, using the same door closer arrangement, it is possible to provide two different torque classes. The invention also takes into consideration the other requirements of the torque classes (for example, EN3 and EN4) in order that these too are met, such as the functional areas of the adjustment valves of the door closer, angle of opening, etc.
- In light of the examples presented above, it is obvious that an embodiment according to the invention can be provided by various solutions within the scope of the independent claim.
