Definitions

  • the present invention refers to an aerial door closer with improved means of rotation. This closer is suited to be mounted on wing doors or the like.
  • the door closer in question is new since it is provided with means for the control of the unit of rotation, which means consists of a piston body subdivided in two semi-parts which are connected each other rigidly and act in contrast with a spring.
  • the means of control includes the hinge of the door which is subjected to pushing rollers in the opening and closing movements.
  • the present door closer is provided with improved means of rotation for an angular displacement of the cam.
  • such means is conceived in such a way as to synchronize the movements of the rollers by connecting same each other by using an only spring for the control of both positioned rollers.
  • the door closers can be subdivided in two basic categories: the floor door closers and the aerial door closers.
  • the closers are used in structures for the control of wing doors such as the swing doors so as to control both the opening and the closing of the door.
  • door closers are suitably used to control the movements of a free door in that the door closer prevents the door to open in presence of wind and permits the door to automatically close without using the hands.
  • the aerial door closers to which the present invention pertains consist basically of a body in the inside of which a chamber is obtained in which a rack piston runs in contrast with a spring.
  • the run of the piston controls the rotation of a pinion fixed to a going-out pivot arranged on ball bearings.
  • the present invention is included therefore in that field and proposes to solve the above-mentioned inconveniences by utilizing an aerial-type door closer provided with improved means for an angular displacement of the cam. More precisely, the means in question is conceived above all in such a way as to synchronize the movements of the rollers which are directly connected with each other.
  • the present solution derives from an Italian utility model filed by the same applicant, i.e Italian utility model application No. VR94U000012, referring to a "Floor Device or Floor Door Closer", characterized in the presence of two rollers arranged on a same slide.
  • a first advantage deriving from the general aim consists in simplifying the mechanical components utilized in the door closer, for instance only one spring is used to control both rollers which are positioned on an only slide.
  • Another advantage offered by the present invention is to realize an aerial door closer including safer mechanical components as concerns the functionality. In fact, a direct contact of the pins for the application of the rollers on the pistons with their slide chamber is avoided.
  • an aerial door closer provided with improved moving means including a body in the inside of which a cylindrical room is obtained in which a piston slides against a spring and acts together with a cam fixed to the closing pivot of the door and/or to the rotation arm thereof, characterized in that the said piston, which runs in contrast with a spring, is divided in two semi-parts which are reciprocally connected through a cross-bar and/or other similar connecting means and in that the insides of the said semi-parts support two rollers which are fixed to each other and are reciprocally opposite in respect to a central cam on which the closing pivot of the door acts, which rollers are kept by pins fixed within both pistons by means of a pawl or the like.
  • number 1 denotes a door closer according to the present invention on the whole.
  • the door closer is represented in a sectional way.
  • the door closer 1 consists basically of a containing body 2.
  • the body 2 contains movable components which cause the opening and/or closing of the door and/or arm of the door closer, the arm of the door closer being mounted on a square pivot 3.
  • first piston 4 In the inside of the cylindrical hollow body 2 there is a first piston 4, connected with a second piston 6 through a plate 5, the second piston 6 being coaxial and specular to the first piston 4.
  • the second piston 6 is arranged in contrast with a spring 7 which maintains a pushing condition between two outer covers 8 and 9.
  • the plate 5 is connected with both pistons in that it engages pins 10 in the inside of the pistons.
  • the pins 10 act also as pivots for the support and rotation of rollers 11 and 12.
  • first piston 4 and the second piston 6 include capsules 4' and 6' .
  • valve screws 15 are not only components through which the oily fluid passes, but they are also elements for blocking the capsules inside the pistons.
  • capsules 4' and 6' avoids the necessity of engaging pins 10 through pistons 4 and 6 and prevents the pins 10 to come in touch with the slide chamber and to cause possible scratches as it occurred in the known solutions.
  • Rollers 11 and 12 contain two opposite sides of a cam 13 from which the square pivot 3 goes out transversally, the square pivot 3 being arranged on suited ball bearings 14.
  • cam 13 shows a particular "hearth” shape so as to give the rotation of the pivot 3 ending positions in elastic contrast in the dead point as well as intermediate pushing positions.
  • both opposite borders which form the hearth cam, are not exactly symmetric and specular for the more projecting side causes a wider displacement of the pushing unit and consequently, a higher adjusting of the movement.
  • the pair of rollers 11 and 12 is positioned off-axis in respect to the centre of the cam 13 so as to allow an increase in the pushing strength of the door closing device, for instance in case of heavy doors, for which more strength is needed in the closing phase.
  • the two pistons are connected through a particularly shaped body 16 while in the preceding solution the pistons were connected through an essentially flat plate.
  • a technician of this field can modify the so-described and represented aerial door closer, given as an example that does not restrict the invention, with some variants referring to means that are technically equivalent to the described ones so as to obtain solutions to be considered included in the scope of protection of the invention as defined in the following claims.
