Definitions

  • the present disclosure relates to a door threshold, and especially to a door threshold being moveable between two positions.
  • a standard threshold for a door has an appearance adapted to function based on the requirements that apply regarding, among other things, sealing and fire requirements.
  • the edge that exists to meet these requirements is unfortunately an obstacle for wheelchair users.
  • the society should be accessible to all. Regardless of functional ability, it must be possible to be involved in society. There may be regulations on easily remedied obstacles in the built environment that states that entrances, balconies, terraces and patios must be accessible, which means that they should be designed without level differences, unless there is a need for a threshold for humidity or climate reasons. However, this should be as low as possible and be phased. Moisture safety has historically largely been handled at openings in a building with the help of level differences between the wet and the dry side. The issue of accessibility means in these situations that the possibility of level differences is limited, i.e. opportunities for threshold and plinth, which gives a built-in conflict in the design of the building.
  • the solution needs to be adapted for requirements and directives; adapted for passage with a wheelchair; and adjustable to be able to mount the threshold regardless of conditions.
  • the provided solution may meet the requirements to function as a standard threshold in its basic position and then be converted into a solution adapted for wheelchairs when a wheelchair is to pass.
  • a door threshold for arrangement below a door at a doorway wherein the doorway is located between a first floor or ground surface and a second floor or ground surface, the first floor or ground surface having a height difference to the second floor or ground surface.
  • the door threshold comprises a bottom member configured to, when in use, be arranged on a horizontal bottom surface of the doorway; a first ramp member configured to, at a first end of the first ramp member, when in use, be in contact with the first floor or ground surface; a second ramp member configured to, when in use, extend from the bottom member towards the second floor or ground surface; a spring member in a first end attached to the bottom member; and a link member in a first end rotatably attached to a second end of the first ramp member and in a second end connected to a second end of the spring member.
  • the spring member provides a biasing force to the first ramp member towards a resting state, and when a force is applied on the first ramp member, the first ramp member moves towards a down pressed position by rotating around the first end of the first ramp member.
  • the first ramp member may extend from the first floor or ground surface towards a door in the doorway, when the door is closed.
  • the first ramp member may then extend in as an upward sloping ramp towards the door.
  • the closed door may then be closed to, or adjacent to, the upward end of the first ramp member.
  • the second ramp member may extend towards the second floor or ground surface.
  • the height difference between the first and second floor or ground surfaces may be provided in the doorway such that the first floor or ground surface may be arranged higher than the second floor or ground surface.
  • the first floor or ground surface may be at an inside of a house or room, and the second floor or ground surface may at an outside of a house or room.
  • the door threshold In the resting position, when nothing or no one passes through the doorway, the door threshold may provide the function of a standard door threshold in terms of fulfilling the requirements of e.g. sealing at a doorway.
  • the first ramp member When someone passes the doorway, either by foot, wheelchair or other equipment, the first ramp member may be pressed downward to a down pressed position. In the down pressed position, the second end of the first ramp member may be moved in the vertical direction to be at substantially the same height as the closest end of the second ramp member. The second end moving towards the down pressed position may be provided by the first ramp member rotating around the first end of the first ramp member. The first end being in contact, fixed or moveable relative to the first floor or ground surface. The door threshold may thereby provide a smooth movement of any wheel based equipment passing.
  • the door threshold may provide an effective way of enabling a smooth passing through the doorway at the same time as e.g. sealing requirements are fulfilled. Further, the door threshold may provide a solution of a flexible threshold that remains arrangeable in a doorway without any need for damage or modification of the door or door lining.
  • the door threshold may be mounted in both new installations (new building/room) and as replacement of a previous door threshold in an existing doorway.
  • the door threshold may be mounted in an integrated manner with the door lining.
  • the first ramp member When moving from the resting position towards the down pressed position, the first ramp member rotates around the first end of the first ramp member. In the resting position there may be a height difference in the vertical direction between the second end of the first ramp member and the second end of second ramp member (i.e. the end of the second ramp member being located closest to the first ramp member). In the down pressed position, the height difference between said second ends of the ramp members may be reduced or said second ends of the ramp member may be at substantially the same height. In one embodiment, the down pressed position may be a horizontal position wherein the first ramp member extends substantially horizontally, e.g. in parallel with the first and/or second floor or ground surface.
  • the force to the first ramp member may be directed, at least partly, downward in a vertical direction.
  • the first ramp member may then move downward in the vertical direction towards the down pressed position. At least a part of the first ramp member may move downward towards the down pressed position. It may be one end of the first ramp member moving in the vertical direction relative the other end.
  • the horizontal bottom surface may be floor or ground surface between the first and second floor or ground surfaces.
  • the bottom surface may be a portion of one of the first and second floor or ground surfaces, preferably the second floor or ground surface, located in the doorway.
  • the second ramp member may extend towards the second floor or ground surface all the way to be in contact with the second floor or ground surface.
  • the second ramp member may be configured to be attached to a door sill extending to be in contact with the second floor or ground surface.
  • the door sill may provide a flexible extension to the second floor or ground surface, flexible depending on how the second floor or ground surface is configured.
  • the second ramp member may be configured to be fixed to and/or to rest on the second floor or ground surface and/or the bottom surface.
  • the spring member may be attached directly or indirectly to the bottom member.
  • the spring member may be rotatably attached at the first end to the bottom member so as to be capable of rotating relative to the bottom member when the first ramp member is moved towards the down pressed position.
  • the spring member may be connected to the bottom member in a hinge like manner.
  • the spring member may provide the connection between the bottom member configured to be fixed to the bottom surface, and the moving members of the door threshold, i.e. the first ramp member and the link member.
  • the spring member may be rotatably attached to the link member. The spring member may thereby control the movement of the link member, and provide stability to the arrangement of the link member and the first ramp member.
  • the spring member may be configured to control movement of the link member, and thereby also the first ramp member, in the vertical direction and/or the horizontal direction (throughgoing direction).
  • the spring member may be attached to the bottom member at a location closer to the first floor or ground surface than a location where the spring member is attached to the link member.
  • the spring member may have a longitudinal extension from the first end of the bottom member towards the second ramp member and/or with an angle to the bottom surface, said angle being between 0-60 degrees depending on the position of the first ramp member.
  • the spring member and the link member may be configured such that, when a force is applied on the first ramp member such that the first ramp member moves towards the down pressed position, the first ramp member may further move towards the second ramp member in a horizontal direction (throughgoing direction).
  • the first ramp member may not be fixed to the first floor or ground surface.
  • the first ramp member When the first ramp member is pressed downward towards the down pressed position, the first ramp member may further move in a horizontal direction to move closer to the second ramp member.
  • the horizontal direction may be a direction perpendicular to the vertical direction.
  • the horizontal direction may further be referred to as a throughgoing direction, i.e. the direction along which the doorway may be passed.
  • the horizontal direction may be in parallel to the first floor or ground surface, and/or the second floor or ground surface.
  • the first end of the first ramp member may be configured to be fixed to the first floor or ground surface in the horizontal direction.
  • the first may be configured to be rotatable relative to the first floor or ground surface, but not moveable in the horizontal direction.
  • the door threshold may comprise a plurality of spring members.
  • the plurality of spring member may be distributed along the longitudinal extension of the door threshold.
  • the longitudinal extension may be in a longitudinal direction of the width of the doorway in which the door threshold is configured to be arranged.
  • a horizontal distance between the first ramp member and the second ramp member may be reduced.
  • the horizontal distance may be seen as a gap between the two ramp members.
  • the first ramp member When being moved downward towards the down pressed position, the first ramp member may further move towards the second ramp member such that said horizontal distance may be reduced.
  • the horizontal distance may be reduced to zero or close to zero.
  • the horizontal distance, along the horizontal or throughgoing direction may be between 1-5 cm, or preferably between 1-2 cm.
  • the horizontal distance may be reduced towards 0-1 cm. With a reduced horizontal distance, the door threshold's surface may be smooth and easy to pass for e.g. a wheelchair.
  • the door threshold may further comprise a flexible sealing member arranged to cover a gap between the link member and the second ramp member.
  • the horizontal distance between the first ramp member and the second ramp member may provide a gap which may be sealed by the sealing member.
  • the sealing member may provide a safety function, such that nothing may be clamped between the members of the door threshold when the first ramp member is moved. It may further prevent dirt or objects to reach down, into the door threshold, interfering with the function of the door threshold.
  • the sealing member may be made of a flexible material, such as rubber or a flexible plastic, such that it may follow the movement of the members of the door threshold. When the horizontal distance between the ramp members are reduced, the sealing member may be bent, compressed and/or moved to follow the movement, and keep the sealing function.
  • the sealing member may in a first end be arranged to the second ramp member and in a second end be arranged to the second end of the link member.
  • the sealing member may thereby follow the movement of the link member.
  • the sealing member may, when the first ramp member is in the down pressed position, be pressed between the first ramp member and the second ramp member at the end of the sealing member that is attached to the second ramp member.
  • the other end of the sealing member may follow the link member moving below the first ramp member.
  • the second ramp member may be attached, at a first end, to the bottom member, and the sealing member may be attached to the bottom member at the location where the second ramp member is attached to the bottom member.
  • the second ramp member may be attached to the bottom member at the location where a top surface of the second ramp member ends.
  • the sealing member may be attached to the second ramp member.
  • the bottom member and the second ramp member may be integrally formed. The sealing member may then be attached at the location where the top surface of the second ramp member ends, and the portion forming the function of the bottom member begins.
  • the second end of the first ramp member and a second end of the second ramp member may be at substantially the same height in a vertical direction.
  • the transition between the ramp members may then be as smooth as possible, preventing a significant vertical step when moving between the two ramp members.
  • the link member when the first ramp member is in the resting position, extends in a substantially vertical direction.
  • the link member may then constitute a vertical portion of the door threshold facing a side surface of the door when the door is closed. This may fulfil necessary requirements of a door threshold at a doorway when the door is closed.
  • the link member may extend in the vertical direction from the second end of the first ramp member in direction towards the bottom member.
  • the first ramp member may be configured to, when being moved towards the down pressed position, rotate around the first end of the first ramp member, at the same time as the first end moves along the first floor or ground surface in a horizontal direction.
  • the horizontal direction may be a throughgoing direction through the doorway, a direction perpendicular to the vertical direction.
  • the link member when the first ramp member is moved towards the down pressed position, may be configured to rotate in a rotational direction towards a bottom side of the first ramp member.
  • the link member may thereby move from a substantially vertical extension in the resting position, rotating into under the first ramp member when moving towards the down pressed position.
  • the spring member is a plate spring.
  • the plate spring may provide the necessary spring force to the resting position of the first ramp member at the same time as keeping the connection to the link member.
  • the function of the plate spring member may further control the movement of the link member to rotate relative to the first ramp member when the first ramp member moves towards the down pressed position.
  • the connection of the spring member between the bottom member and the link member further provides the first ramp member's movement in the horizontal direction towards the second ramp member.
  • the bottom member may have a horizontal portion extending between a first end and a second end, wherein the second ramp portion is attached to the second end of the horizontal portion, and the spring member is attached to the first end of the horizontal portion.
  • the bottom member may further comprise a vertical portion extending from the second end of the horizontal portion vertically upwards.
  • the second ramp member may be fixed to the upward end of the vertical portion, thereby attached to the horizontal portion via the vertical portion.
  • the bottom member and the second ramp member may be integrally formed such that the second ramp member is a continuing portion from the vertical portion.
  • the bottom member and the second ramp member may thereby form a fixed portion of the door threshold, fixed, when in use, relative to the floor or ground surfaces, and the spring member, link member and first ramp member may constitute moveable portions of the door threshold, moveable relative to the fixed portion and, when in use, the floor or ground surfaces.
  • the second floor or ground surface may have a lower height in a vertical direction than the first floor or ground surface.
  • the door threshold may further comprise a link arm arranged between the bottom member and the link member.

  • the link arm may in a first end be rotatably arranged to the first end of the bottom member, and in a second end rotatably arranged to the link member.
  • the link arm may be fixed relative to the bottom member in the horizontal direction, thereby causing, together with the spring member, the link member to rotate relative to the first ramp member when the first ramp member moves towards the down pressed position.
  • the link arm may be rotatably attached to the bottom member in a hinge like manner.
  • the biasing force provided by the spring member to move the first ramp member towards the resting position may also affect the link arm.
  • the link arm and the spring member may have a common rotatable attachment to the bottom member.
