  • Patent WO2018/002805 HINGE FOR THE ROTATABLE MOVEMENT OF A DOOR OR OF A SIMILAR CLOSING ELEMENT", of the year2017, in the name of COLCOL GROUP, refers to a hinge for the rotatable movement of a door (D) or of a similar closing element anchored to a wall (W) or to a similar stationary support, the hinge comprising a fixed element couplable to the wall (W) or to the similar stationary support and a movable element couplable to the door (D) or to the similar closing element.
  • the fixed and movable elements being rotatably coupled to each other to reciprocally rotate between an open position and a closed position around a first longitudinal axis.
  • one of the movable elements and the fixed element includes a hinge body, the other of the movable element and the fixed element including at least one pivot defining the longitudinal axis (X).
  • the pivot comprises cam means rotating around the axis (X) and the hinge body comprises at least one working chamber defining a second axis (X') substantially parallel to the axis (X) and spaced apart thereto.
  • the working chamber further comprises at least one slider sliding along the axis (X') between a first and a second end stroke positions.
  • the hinge further comprises cam follower means engaged with cam means and interacting with the slider so that the rotation of the movable element around the axis (X) corresponds to the slinding of the slider along the axis (X').
  • the applicant firm is the owner of the European Patent Application No. 2472036 "HYDRAULIC MECHANISM FOR DOOR OPENING", of the year 2011, which refers to a hydraulic mechanism for opening doors of the type fixed to a structure, such as a wall, frame or floor of the type comprising a base with two covers between which covers the door is fixed by securing means, characterised in that it comprises: an eccentric shaft, a first piston, connected to at least one spring and to the eccentric shaft and a closed circuit with lubricant fluid or oil that moves in function of whether the referred spring is compressed or decompressed, thus regulating the door-opening or closing speed.
  • the base is combined with the fixing plate and has an oil passage.
  • the oil passage is formed in the base.
  • the pivot is rotatably mounted in the base and has an adjusting space communicating with the oil passage.
  • the buffer module is mounted in the base and has a sliding tube abutting the pivot.
  • the clamping module is pivotally mounted on the pivot and can clamp a glass door.
  • the glass door can be pivoted relative to the base. With the buffer module and the oil passage, the glass door can be closed in a smooth movement.
  • Patent US2009188082 "ADJUSTABLE GLASS HINGE, in the name of Shih-Chang Huang, from 2008, describes an adjustable glass hinge mainly includes a fastening assembly fastened to a door frame and a clipping plate assembly to clip a glass panel.
  • the fastening assembly includes a fastening seat, two bucking elements disposed from one side in the fastening seat and coupled respectively with an elastic element, a pintle running through another side of the fastening seat and a seat board fastened to the fastening seat.
  • the clipping plate assembly has a first clip plate and a second clip plate that are coupled together, two pads held on an inner side of the first and second clip plates and a clipping blade to hold and confine two directing members. Alignment of the glass panel can be accomplished quickly.
  • the present invention falls within the field of hydraulic hinges for opening glass doors with automatic closing.
  • Patent US2009188082 The closest document is Patent US2009188082 .
  • Said patent solves the problem of how to fix the eccentric axis in the cover by means of a fixing system, by means of a threaded pin that goes through a partition in the base and said pin linearly pushes the shoe against the axis.
  • the main problem comes from the fact that due to the weight of the glass door, tensions are generated in the hinge, which can cause that even when the shoe is pressed with the threaded pin, it is very difficult to leave the axis in a specific and secured position, and it can create some kind of slack.
  • this system does not guarantee that the axis will not end up rotating due to the action of the forces that said axis should support when the door is turned, so that after a certain time it has to be disassembled and fixed again.
  • the present invention solves both problems by making cavities in one of the covers, where the ends of the eccentric axis are positioned, and a shoe that blocks said cavity at the same time that, when said shoe is fixed against the cover, it blocks and fixes the eccentric axis by contact.
  • the fixing means contrary to what happens in the background of the invention, is located perpendicular to the lid. This allows that the shoe to absorb the stresses due to the fact that when the fixing means are pressed against the shoe, from one side the shoe is positioned and repositioned by the action of the friction between the slopes, which makes the shoe is pushed against the base by the action of the fixing means and against the axis by the pressure of friction between slopes.
  • the shoe has a position caused by parallel forces to the base and by perpendicular forces to the base, with a single fixing means, generating an adaptability of the shoe to be able to immobilize the end of the axis in a more solid way.
  • This shoe can then be adapted to small imperfections at the end of the axis, because it will always end up accommodating or adjusting to the end of the axis and will be able to fix said end of the axis.
  • the eccentric axis being inside the cavities, is in a stable position, which makes it easier for the shoe to be fixed to it, and at the same time, as the shoe is fixed against the cover and, in addition, there is a double contact between the shoe against the cover and the shoe against the end of the axis, the contact surface is increased and the fixation is ensured.
  • An object of the present invention is a hydraulic hinge for glass doors, of the type that comprises a base with two covers, between whose covers the door is fixed, a hydraulic circuit and an eccentric axis that is fixed to one of the covers, characterized in that the cover that is fixed to the eccentric axis comprises: - cavities, one per end of the axis, with a first slope, and which configure a second slope in its upper part, which reduces the inner space of the cavity, - shoes that block the cavities, immobilize the ends of the eccentric axis by contact and are fixed against the cover, and that have a third slope, which is facing the second slope, and - fixing means, which are fixed to the shoes, arranged perpendicular to the cover.
  • FIG. 1 a base 1, a cover 3 and a hydraulic circuit 4 are illustrated.
  • Figure 2 shows a cover 2, an eccentric axis 5 with its end 7, cavities 6, a first slope 8 and a shoe 9.
  • Figure 3 shows the cover 2, the eccentric axis 5 with its end 7, the cavities 6, the first slope 8, a second slope 10, a third slope 11, the angle ( ⁇ ), the angle ( ⁇ ) and the shoe 9 with its screw 12.
  • the device of the present invention is a hydraulic hinge, one of those installed to fix glass doors, with an automatic closing system.
  • It comprises a base 1 that is fixed to a wall or fixed structure, with two covers 2, 3, between whose covers the door is fixed, a hydraulic circuit 4 that will serve to allow the return of the door, and an eccentric axis 5 that it is fixed to one of the covers 2.
  • the cover 2 that is fixed to the eccentric axis 5 comprises cavities 6, one per end of the axis 7, with a first slope 8 and some shoes 9 that block the cavities 6, immobilize also the ends 7 of the eccentric axis 5 by contact and are fixed against the cover 2. In this way, the operator can place the eccentric axis 5 in the correct position without hardly any effort, leaving it immovably fixed.
  • the cavities 6, in their upper part, comprise a second slope 10, which reduces the inner space of the cavity 6, and because the shoes 9 comprise a third slope 11, which faces the second slope 10.
  • This combination of slopes allows the operator to regulate the pressure of the shoe 9, said shoe always remaining fixed.
  • the shoe 9 can be adapted to different types of ends 7, of different sizes, since the slopes 10, 11 always allow the shoe 9 to be fixed and locked against the walls of the cavity 6.
  • fixing means 12 in this embodiment a screw, which are fixed to the shoes 9, arranged perpendicular to the cover 2.
  • the angle ( ⁇ ) of the third slope 11 is between 20° and 40°, that is, the angle taken in relation to the position of the base 1.
  • angle ( ⁇ ) of the second slope 10 it would be possible to configure the angle ( ⁇ ) of the second slope 10 to be equal to or greater than the angle ( ⁇ ), thus allowing the shoe 9 to adapt to the end of the axis 7 and to the stresses to which it may be subjected.
  • the fixing means 12 are located above the end of the axis 7, and mostly or totally in the upper half of the shoe 9. This is done to allow a small tilting of the shoe 9 when fixing and that it can be adapted to the end of axis 7.
  • the shoes 9 can be made of metal to provide greater rigidity.
  • the operator would place the end of the axis 7 inside the cavities 6.
  • the first slope 8 would allow a correct placement of the end of the axis 7 in the cavity 6.
  • the inventors have verified that if the angle ( ⁇ ) of the third slope 11 is between 20° and 40°, the end of the axis 7 is immobilized efficiently.
  • the variation depends on the materials used and the stresses that the end of the axis 7 can receive. For example, there may be variations between a displaced or centered base 2 or depending on the thickness of the glass.
  • angle ( ⁇ ) of the second slope 10 it would be possible to configure the angle ( ⁇ ) of the second slope 10 to be equal to or greater than the angle ( ⁇ ).
  • the second slope 10 can always guide it downwards and into the cavity 6, thus allowing the shoe 9 to adapt to the end of the axis 7 and the tensions to which it may be subjected.
  • the proposed angles would be the same as for angle ( ⁇ ).
  • the screw 12 being located above the end of the axis 7, and mostly or completely in the upper half of the shoe 9, allows that while the screw 12 is being screwed, and the second slope 10 pushes the third slope 11 for the end of the axis 7, this asymmetry of being located the screw 12 in the upper half of the shoe 9 makes it possible to adapt, to have a small tilt so that it can be better adjusted to the end of the axis 7.
  • the present invention describes a new hydraulic hinge for glass doors.
  • the examples mentioned here are not limiting of the present invention, therefore it may have different applications and/or adaptations, all of them within the scope of the following claims.
