Definitions

  • the present invention relates to a hinge with a damping function thanks to which doors, windows and other opening elements of conditioned or refrigerated rooms will be closed self-acting.
  • the present invention relates to a hinge with a damping function for swing fitting of doors or windows of rooms or other openable elements, in particular refrigeration cabinets and chambers, and comprising a first fastening set and a second fastening set as well as a damping unit located between the first fastening set and the second fastening set, whereby when one of the first fastening set and the second fastening set is mounted to a casing frame, the other one is mounted to a window leaf frame or door leaf frame.
  • a door hinge with a damping function is known from the publication DE 19717117 A1 , comprising a case, the first rotation pin, the second rotation pin, a U-shaped rotation pin, a hinge cup, a connecting element, a torsion spring, a coupling, a bearing case and a damping part.
  • One end of the connecting element swivels in the case using the first rotation pin, and the second end of the connecting element is swivel-connected with the hinge cup using one arm of the U-shaped rotation pin
  • one end of the coupling swivels in the case using the second rotation pin, and the second end of the coupling is swivel-connected with the hinge cup using the means of the second arm of the U-shaped rotation pin.
  • the torsion spring is fastened to the second rotation pin, whereas one end of the torsion spring is fastened to the connecting element, and the other end of the torsion spring rests against the connecting element.
  • the bearing case is fastened to the connecting element, whereas the damping case is supported by the bearing case.
  • the publication MX 2018010668 A1 discloses a hinge with two sections linked by a hinge pin. One section holds the hinge pin via a rolled section.
  • the damping is provided by an elastic insert clipped to one hinge section and pressing onto the outer profile of the other section.
  • the damping effect is variable over the range of movement of the hinge, without a damping effect in one setting of the hinge.
  • the insert has one friction surface which is pressed onto the external profile of one hinge section to generate the damping of movement while closing.
  • publication US 20190040667 A1 provides an apparatus connecting a door hinge and a door closer.
  • the hinge provides a variable hydraulic damping speed control with spring-action closing, as well as an optional stop action.
  • the hinge of the present invention includes an adjustable compression spring to operate the opening and closing of a door. When the door's angular position is approximately 20 degrees, the hydraulic component of the door may then control the speed of the door closing, preferably from approximately 20 degrees until closed. Additionally, in one embodiment, the closing function allows the door to remain open in a specific position.
  • publication JP 2018 009380 A titled teaches a gravity hinge with a built-in hydraulic damper which is vertically mounted on an upper location within a cylinder part in an upper part of a hinge.
  • a tip of the hydraulic damper abuts on a tip of a shaft to make the tip recede.
  • the gravity hinge with the damper can reduce a speed until the completion of closing of the door.
  • Publication EP 2 803 799 A2 relates to a hinge for pivoting a substantially flat section, in particular a door leaf of a shower partition.
  • the hinge has a section-side fixing area or a first hinge and a body-side hinge area or a second hinge and the two fixing areas or hinge straps that are pivotably connected to one another via a hinge pin provided with a locking mechanism consisting of a lifting-lowering mechanism and a compression spring.
  • the hinge pin being connected via a conical or with section formed with a similar effect and a driver with a rotary brake is in a form-fitting and force-fitting operative connection.
  • the purpose of this invention is to create a simple-design hinge with a damping function, which could be used for swing fitting of doors or windows or other openable elements of air-conditioned or refrigerated rooms and which also would enable automatic closing of such doors or windows in a slowed-down movement.
  • a basic idea of the invention is that when opening the window or door or another openable elements of air-conditioned or refrigerated rooms, energy is collected, which, when the force holding the doors, windows or other openable sash ceases, causes the return movement of the mentioned doors, windows or other openable elements.
  • the hinge with the damping function comprises a first damping set comprising a first cam non-rotatable in relation to the housing of the first fastening set and shaped like a cylinder open at a side of a middle of the hinge and having a facing surface with at least one protrusion directed towards the middle of the hinge, a second damping set comprising a second cam non-rotatable in relation to the housing of the second fastening set and shaped like a cylinder open at the side of the middle of the hinge and having a facing surface faced towards the facing surface of the first cam and comprising at least one skid with an inclined slope.
  • a particularly efficient operation of the device according to the invention is that at least one skid or ramp with an inclined slope has a difference of level between 2 mm and 30 mm that is equal to a difference between a quantity b in an open position of a window or door or another closing element, as measured between an inner surface of the housing of the first fastening set and an outer surface of the housing of the second fastening set, and a quantity a in a closed position of the window or door or another closing element, as measured between the inner surface of the housing of the first fastening set and the outer surface of the housing of the second fastening set, whereas the interiors of the first cylinder and the second cylinder form a central space or a central chamber, and a damping operator is situated in the central space or the central chamber that has an actuating cylinder filled with a medium and closed at one end, and surrounded, at least partially, by a first cylindrical shell of the first cam and a second cylindrical shell of the second cam, and a piston with at least one pass-through opening and a
  • a sleeve with a length not greater than a length of the actuating cylinder, rotatably mounted in relation to at least one of the first cylindrical shell or mantle of the first cam and the second cylindrical shell or mantle of the second cam.
  • the damping operator is an actuator with a movable float tightly dividing a chamber between a bottom of the actuating cylinder and a piston into two parts, whereas a section between the piston and the float contains a medium that during the movement of the piston towards the bottom of the actuating cylinder, flows into the chamber between the piston and the closing element through pass-through openings in the piston, whereas a bottom chamber between the float and the bottom of the actuating cylinder contains compressed gas forcing the piston to return to the position in which the piston rod is most extended or is outermost.
  • the damping operator can have a spring located between a bottom of the actuating cylinder and a piston with pass-through slots or openings enabling a flow of a medium from a space enclosed by a wall of the actuating cylinder and located between the bottom and the piston to a space enclosed by the wall of the actuating cylinder between the piston and a lid of the actuating cylinder, with an opening for the piston rod.
