    HINGE ARRANGEMENT
    20185520 PRH 07-06- 2018
    TECHNICAL FIELD [0001] The present application generally relates to a hinge arrangement. In particular, but not exclusively, the present application relates to a hinge arrangement for a glass door.
    BACKGROUND [0002] This section illustrates useful background information without admission of any technique described herein being representative of the state of the art.
    [0003] Arranging hinges for doors with a heavy door leaf, for example glass 15 doors, can be problematic, in particular if the door leaf is frameless. For example glass door leafs tend to twist and pull on the hinges, so that the closing and sealing of the door becomes difficult, especially as glass door leaves rarely are completely straight to begin with. This problematic is emphasized in situations in which the sealing of the door is important, for example for soundproofing.
    [0004] Furthermore, as the above problems require sturdy hinges, their appearance is not always visually pleasing, or they have a complicated structure raising manufacturing costs and requiring laborious assembly. Moreover, previous self-closing hinge arrangements are typically small spring loaded flap hinges many of which would be required for sturdiness of the door leaf.
    [0005] Examples of sealing arrangement in which a profile spanning the length of the door is provided have been previously disclosed, for example in publications DE202011103476U1, EP1831491B1 and KR200403180Y1. These examples do not provide for a simple arrangement or sturdiness required for heavy door leaves, nor do they enable a self-closing door.
    [0006] The present invention aims to provide a hinge arrangement that overcomes or at least mitigates the above-mentioned challenges.
    SUMMARY [0007] Various aspects of examples of the invention are set out in the claims.

    a lower and upper hinge pin arranged inside the lower and upper end of the profile and inside the lower and upper attachment element, respectively;
    further comprising a spring element extending through the profile, the lower and upper attachment element and lower and upper hinge pin and configured to provide sturdiness, wherein the spring element is attached at one end with the lower or upper attachment 15 element and at the other end with the profile or with the lower or upper hinge pin and configured cause tension pulling the hinge arrangement to a closed position.
    [0009] The spring element may comprise a steel rod.
    [0010] The spring element may be bent at one end and the bent portion is configured to be attached to the lower or upper attachment element by nesting within a recess.
    [0011] The lower and/or upper hinge pin may be rotatably arranged inside the profile and the arrangement may further comprise a bearing between the edge of the profile and a thicker portion of lower and/or upper hinge pin.
    20185520 prh 07-06- 2018 [0012] The profile may comprise a recess for receiving and holding a door leaf.
    [0013] The profile may comprise aluminium or steel.
    [0014] The profile may comprise a sealing protrusion configured to abut against a doorframe in a closed position of the hinge arrangement.

It is to be noted that although Fig. 4 shows the hinge arrangement 100 according to an embodiment of the invention being applied in soundproof space, the hinge arrangement is equally well applicable to any door.
    [0036] Fig. 5 shows a flow chart of method of operating a hinge arrangement according to an embodiment of the invention. The door closing sealing is based on 20 the tension provided by the spring element 30. As the door is opened, the spring element is twisted around the longitudinal, i.e. vertical axis thereof due to one end being attached to the door leaf via the profile 10 or a hinge pin 20a,20b fixedly attached to the profile 10 and the other end of the spring element 30 being attached to an attachment element 40a,40b for example by nesting the bent end thereof in a 25 recess of the attachment element.
    [0037] At step 500 the hinge arrangement 100, and consequently the door, is open and tension is caused by twisting of the spring element 30. In an embodiment, the spring element is arranged in such a way that it is configured to be twisted also in closed position of the hinge arrangement 100, and consequently of 30 the door, so that a tension is present in all positions of the door. At step 510, the tension caused by the spring element causes the door to be pulled closed, i.e. the hinge arrangement is configured to provide as self-closing door. Subsequently, at step 520, the sealing protrusion 14 of the profile 10 abuts against the doorframe and the seal element between the sealing protrusion 14 and the doorframe seals the gap
    20185520 prh 07-06- 2018 so that for example soundproofing is improved. As hereinbefore noted, in an embodiment, a tension remains in the closed position as well and the sealing is improved and held while the spring element 30 extending through the whole length of the door provides for sturdiness and support to the arrangement. In an 5 embodiment, in addition to the force caused by the spring element 30, a latch and/or a magnetic arrangement is provided for ensuring the closing of the door.
