- the present disclosure relates to a door handle arrangement, and especially an arrangement for a door handle used in industrial applications.
- a door handle as a means to move a latch or locking device for opening or closing of doors is a common way of arranging the opening or closing of a door.
- a need to control the opening of the door such that it is not uncontrollably flung open. This may for example be the case when the door is located in a ceiling or that there may be a pressurized fluid in the space to be opened.
- the pressurized fluid may cause an explosive opening of the door when a lock or handle is opened. This may injure a user opening the door.
- a door handle solution which prevent the opening of a door to a pressurized space to injure a user.
- a handle arrangement for a door comprising a handle arranged to move rotationally around a rotational axis C between an open state and a closed state, and a locking means for engaging with a locking element on a door frame, and further comprising an intermediate link arranged between the handle and the locking means and arranged for transforming the rotational movement of the handle to substantially linear movement of the locking means, a connection element, wherein the handle is connected to the intermediate link by the connection element, and the intermediate link is arranged to perform a movement following an arcuate path when the handle is moved between the open state and the closed state.
- a handle arrangement comprising a handle and a locking clamp for engaging a locking element on a door frame.
- the locking clamp is arranged to rotate around a first axis from a locking position to an intermediate position when the handle is moved from a closed state towards an intermediate state.
- the locking clamp is arranged to move linearly along a second axis from the intermediate position to an open position when the handle is moved from the intermediate state towards an open state.
- the handle arrangement comprises a resilient means arranged to, by a resilient force, keep the locking clamp from moving from the intermediate position towards the open position until a force applied in the direction of the linear movement of the locking clamp towards the open position exceeds the resilient force of the resilient means.
- a handle arrangement which may be opened in several steps is provided.
- the opening of a door, cabinet or window may be performed in a controlled manner.
- the arrangement further provides a simple construction where no additional parts are required to achieve the multi-step function of the handle arrangement.
- the intermediate position of the locking clamp and intermediate state of the handle are defined as a position or state in-between the open and locking/closed position or state respectively.
- the locking clamp When the locking clamp is rotated around the first axis from the locking position into the intermediate position, the locking clamp may be partly released from a locking element of a door frame or wall such that the door remains closed but the pressure may be released.
- This intermediate position allowing the pressure to drop, ensures that the door is not uncontrollably flung open due to a pressure difference between the enclosure to be opened and the surrounding area. It may also serve as a protection for a door which opens downwards from for example a ceiling or tilting wall such that the door does not fall downwards uncontrollably.
- the handle When the pressure has been released, or control achieved, the handle may be turned from its intermediate state to its open state, which also causes the locking clamp to move from its intermediate position into its open position. In the open position, the locking clamp is fully retracted and released from the locking element such that the door may be opened in a controlled manner.
- the handle arrangement may further comprise an actuator, wherein the actuator may be arranged between the handle and the locking clamp and arranged to move linearly along the second axis.

- the link may be rotatably arranged to the locking clamp at a first end and rotatably arranged to the actuator at a second end.
- the rotatable connection between the link and the actuator and the locking clamp respectively may provide for a movement where the second end arranged to the actuator may move along the second axis and rotate in relation to the actuator, while the first end may rotate in relation to the locking clamp and rotate around its second end away from the second axis.
- the link may enable the rotation of the locking clamp from the locking position to the intermediate position when the actuator moves linearly along the second axis.
- the link may rotate in relation both to the locking clamp and to the actuator, respectively, such that when the locking clamp is in the locking position, the second end of the link and the part of the actuator to which it is rotatably connected, may be located on the second axis while the first end of the link may have been rotated away from the second axis around its second end, being rotatably connected to the locking clamp in its locking position.
- the rotatable connection to the second end of the link implies that as the actuator moves along the second axis, the second end of the link may move with the actuator while the first end of the link rotates around the second end towards the second axis until it reaches a position where no further rotation is achievable.
- the end of the locking clamp to which it is rotatably attached may also be forced to move in this direction, causing a rotation of the locking clamp around the first axis from its locking position towards its intermediate position.
- the first end of the link when the locking clamp is in the intermediate position, the first end of the link may be offset of the second axis relative to the second end of the link.
- the first end of the link being offset of the second axis may provide that the link, when the locking clamp rotates from the intermediate position towards the locking position, pushes the locking clamp such that it is lifted at its end connected to the link, and thereby performs the rotation.
- the link When the locking clamp has been moved from the open position to the intermediate position and further linear movement of the locking clamp is prevented, the link provides a lifting of the locking clamp.

Description
- The present disclosure relates to a door handle arrangement, and especially an arrangement for a door handle used in industrial applications.
- In the field of handles for doors, cabinets, and windows, the use of a door handle as a means to move a latch or locking device for opening or closing of doors is a common way of arranging the opening or closing of a door. In some industrial applications such as electrical enclosures or ventilation ducts, there may be a need to control the opening of the door such that it is not uncontrollably flung open. This may for example be the case when the door is located in a ceiling or that there may be a pressurized fluid in the space to be opened.
- The pressurized fluid may cause an explosive opening of the door when a lock or handle is opened. This may injure a user opening the door. Hence, there is a need for a door handle solution which prevent the opening of a door to a pressurized space to injure a user.
- It is an object of the present invention to provide an improved solution that alleviates the mentioned drawbacks with present devices.
- The invention is defined by the appended independent claims, with embodiments being set forth in the dependent claims, in the following description and in the attached drawings.
- According to a first aspect of the invention, there is provided a handle arrangement for a door comprising a handle arranged to move rotationally around a rotational axis C between an open state and a closed state, and a locking means for engaging with a locking element on a door frame, and further comprising an intermediate link arranged between the handle and the locking means and arranged for transforming the rotational movement of the handle to substantially linear movement of the locking means, a connection element, wherein the handle is connected to the intermediate link by the connection element, and the intermediate link is arranged to perform a movement following an arcuate path when the handle is moved between the open state and the closed state.
- In another solution, there is provided a handle arrangement comprising a handle and a locking clamp for engaging a locking element on a door frame. The locking clamp is arranged to rotate around a first axis from a locking position to an intermediate position when the handle is moved from a closed state towards an intermediate state. The locking clamp is arranged to move linearly along a second axis from the intermediate position to an open position when the handle is moved from the intermediate state towards an open state. The handle arrangement comprises a resilient means arranged to, by a resilient force, keep the locking clamp from moving from the intermediate position towards the open position until a force applied in the direction of the linear movement of the locking clamp towards the open position exceeds the resilient force of the resilient means.
- With this arrangement, a handle arrangement which may be opened in several steps is provided. By this multistep opening, the opening of a door, cabinet or window may be performed in a controlled manner. The arrangement further provides a simple construction where no additional parts are required to achieve the multi-step function of the handle arrangement.
- The intermediate position of the locking clamp and intermediate state of the handle are defined as a position or state in-between the open and locking/closed position or state respectively.
- When the locking clamp is rotated around the first axis from the locking position into the intermediate position, the locking clamp may be partly released from a locking element of a door frame or wall such that the door remains closed but the pressure may be released. This intermediate position, allowing the pressure to drop, ensures that the door is not uncontrollably flung open due to a pressure difference between the enclosure to be opened and the surrounding area. It may also serve as a protection for a door which opens downwards from for example a ceiling or tilting wall such that the door does not fall downwards uncontrollably.
- When the pressure has been released, or control achieved, the handle may be turned from its intermediate state to its open state, which also causes the locking clamp to move from its intermediate position into its open position. In the open position, the locking clamp is fully retracted and released from the locking element such that the door may be opened in a controlled manner.
- According to one embodiment, the handle arrangement may further comprise an actuator, wherein the actuator may be arranged between the handle and the locking clamp and arranged to move linearly along the second axis. The actuator may serve as a means to push or pull the locking clamp into the open, intermediate, and locking positions by executing a force on the locking clamp. When the handle is moved from the closed state towards the intermediate state, the actuator may pull the locking clamp such that the locking clamp rotates to the intermediate position. During such rotation, the resilient means may prevent the locking clamp from moving linearly towards the open position. When the handle is moved further towards the open state, the actuator may pull the locking clamp further to move linearly along the second axis towards the open position.
- According to a further embodiment, the actuator may be coupled to the locking clamp by a link. By coupling the actuator to the locking clamp by a link, the locking clamp and the actuator may move along the second axis between the open and intermediate positions of the locking clamp and the locking clamp may rotate around the first axis between the intermediate and locking positions while the actuator remains to move along the second axis.
- In another embodiment, the link may be rotatably arranged to the locking clamp at a first end and rotatably arranged to the actuator at a second end. The rotatable connection between the link and the actuator and the locking clamp respectively, may provide for a movement where the second end arranged to the actuator may move along the second axis and rotate in relation to the actuator, while the first end may rotate in relation to the locking clamp and rotate around its second end away from the second axis.
- According to another embodiment, the link may enable the rotation of the locking clamp from the locking position to the intermediate position when the actuator moves linearly along the second axis. The link may rotate in relation both to the locking clamp and to the actuator, respectively, such that when the locking clamp is in the locking position, the second end of the link and the part of the actuator to which it is rotatably connected, may be located on the second axis while the first end of the link may have been rotated away from the second axis around its second end, being rotatably connected to the locking clamp in its locking position. The rotatable connection to the second end of the link implies that as the actuator moves along the second axis, the second end of the link may move with the actuator while the first end of the link rotates around the second end towards the second axis until it reaches a position where no further rotation is achievable. As the first end rotates towards the second axis, the end of the locking clamp to which it is rotatably attached, may also be forced to move in this direction, causing a rotation of the locking clamp around the first axis from its locking position towards its intermediate position. In one embodiment, when the locking clamp is in the intermediate position, the first end of the link may be offset of the second axis relative to the second end of the link. The first end of the link being offset of the second axis may provide that the link, when the locking clamp rotates from the intermediate position towards the locking position, pushes the locking clamp such that it is lifted at its end connected to the link, and thereby performs the rotation. When the locking clamp has been moved from the open position to the intermediate position and further linear movement of the locking clamp is prevented, the link provides a lifting of the locking clamp.
- In another embodiment, the second axis may be perpendicular to the first axis. The second axis may be the axis along which the linear movement of the actuator occurs while the rotation of the locking clamp occurs around the first axis. The locking clamp may also move linearly along the second axis as it moves between its intermediate and open positions. When the locking clamp is moved linearly along the second axis, the position of the first axis being the rotational axis of the locking clamp may move along the second axis.
- In another embodiment the locking clamp may comprise at least one pin extending along the first axis. The at least one pin extending along the first axis may serve as the means around which the rotation of the locking clamp occurs when it rotates between its locking and intermediate positions.
- According to a further embodiment, the least one pin may be arranged to interact with the resilient means. The at least one pin may further interact with the resilient means such that the resilient force which may keep the locking clamp from moving from the intermediate position towards the open position is exerted on the pin.
- In yet another embodiment, the resilient means may be a flat spring. The resilient means being a flat spring may provide for shaping the spring such that when the force exerted on the at least one pin is lower than the resilient force, the pin remains still or rotates around the first axis in its current position adjacent the flat spring and such that when the force exerted on the at least one spring exceeds the resilient force, the at least one pin of the locking clamp moves from its current position to another position relative to the flat spring.
- In a further embodiment, the locking clamp may comprise at least one pin extending along the first axis arranged to interact with the flat spring, and wherein the flat spring may comprise a flat portion and a curved portion, wherein the flat spring may be arranged to keep the pin at the curved portion in the locking and intermediate positions of the locking clamp and wherein the pin may be located at the flat portion when the locking clamp is in the open position. The curved portion of the flat spring may have a curvature essentially similar to that of the at least one pin. The curved portion may further keep the at least one pin in position during rotation of the locking clamp. When the force applied in the direction of the linear movement of the locking clamp towards the open position exceeds the resilient force of the spring, the at least one pin moves past the curved portion onto the flat portion of the spring.
- According to another embodiment, the flat spring may comprise a shoulder connecting the flat portion and the curved portion. The portions of the flat spring may be connected by a shoulder which defines the division between the curved and flat sections of the flat spring.
- According to another embodiment, the locking clamp and the resilient means may be at least partially covered by a housing. The housing may protect the locking clamp and the resilient means. The housing may further provide support to the resilient means such that the relevant resilient force can be exerted.
- According to a further embodiment, the resilient means may in one end be attached to the housing and in another opposite end moveable relative to the housing. When a force is exerted on the locking clamp towards the open position, the resilient force of the resilient means may be exceeded such that the resilient means is moved relative the housing by the locking clamp. The resilient means may be moved such that at least the end being moveable relative to the housing is moved.
- According to one embodiment, the resilient means may be a flat spring comprising a flat portion and a curved portion, and wherein the flat spring is moveable relative to the housing adjacent to the curved portion.
- According to one embodiment, the locking clamp may in the locking position be configured to prevent movement of the door relative to the door frame, and in the intermediate position may be configured to enable a limited movement of the door relative to the door frame but prevent complete opening of the door relative to the door frame. In the locking position, the locking clamp may keep the door closed in a locked manner and prevent opening of the door. In the intermediate position, the locking clamp is moved to enable a partly opening of the door relative to the door frame. The partly opening of the door may in one embodiment enable an opening of between 1-5 cm. The partly opening may be limited by the locking clamp in the intermediate position engaging the locking element on the door frame. In the open position, the locking clamp may be moved to enable complete opening of the door relative to the door frame. The locking clamp may in the open position not engage the locking element on the door frame.

FIG. 1 illustrates a door arrangement comprising adoor 10 arranged on adoor frame 70. On the door 10 ahandle arrangement 1 is arranged. -
FIGS. 2a-2c illustrate thehandle arrangement 1 according to an embodiment comprising a lockingclamp 3, ahandle 2, an upper 5 a and a lower 5 b housing, and anactuator 4 coupled to the lockingclamp 3 by alink 7. Thehandle 2 is rotatable around a third axis C as it is moved between its closed, intermediate, and open states. - In
FIG. 2a the handle arrangement is illustrated with thehandle 2 in the closed state and the lockingclamp 3 in the locking position. In the locking position, the lockingclamp 3 has been rotated around the first axis A. The extending pins 31 are located under thecurved portion 81 of theresilient means 8 and in a first corner of thelower housing 5 b, as further illustrated inFIG. 6a . In the locking position, the lockingclamp 3 is configured to be pressed towards a locking element on a door frame 70 (seeFIGS. 7a-7c ), thereby locking thedoor 10 to which thehandle arrangement 1 is attached. Further, in the locking position, theactuator 4 is in a position along the second axis B, where it is stopped from further movement along the second axis B in the direction of the lockingclamp 3 by thelower part 5 b of the housing. - The resilient means 8 may be a flat spring made of metal, hard plastics, or any other material capable of exerting a force on the extending
pins 31 of the locking clamp. There may be twoflat springs 8 in thehandle arrangement 1, one on each side of the lockingclamp 3 as illustrated inFIG. 3 . - The
flat spring 8 is illustrated inFIG. 5 and comprises acurved portion 81 and aflat portion 82. Thecurved portion 83 has a curvature corresponding to the curvature of the extending pin such that the pin may rotate without any impact of the resilient force. Theflat spring 8 further comprises an interactingportion 84 adapted to interact with theupper part 5 a of the housing, further enhancing the resilient force exerted on the extending pins 31. Theflat spring 8 also comprises a graspingportion 85 which is adapted to grasp around the lower part of thehousing 5 b and is fixated between theupper part 5 a and thelower part 5 b of the housing. - In
FIG. 2b , thehandle 2 is in the intermediate state. As thehandle 2 moves to the intermediate state, theactuator 4 moves along the second axis B and, via thelink 7, pulls the lockingclamp 3 to rotate around the first axis A into the intermediate position. As illustrated inFIG. 6b , in the intermediate position, the extendingpin 31 is located under thecurved portion 83 and in a first corner of thelower housing 5 b. -
FIG. 2c illustrates thehandle 2 in its open state. As thehandle 2 is rotated around the third axis C into the open state, theactuator 4 moves along the second axis B and via the link pulls the lockingclamp 3 to move along the second axis B. When the force exerted on the lockingclamp 3 exceeds the force of theflat spring 8, the lockingclamp 3 is moved along the second axis B into the open position. As the lockingclamp 3 moves along the second axis B into its open position, the first axis A around which the lockingclamp 3 rotates, moves with the extendingpin 31 along this axis B into a second corner of thelower housing 5 b and to a position under the flat 82 and interacting 84 portions of theflat spring 8, as further illustrated inFIG. 6c . Rotation of the lockingclamp 3 around the first axis A is prevented by theupper part 5 a of the housing in any other position than the locking position and the intermediate position. -
FIG. 3 illustrates an x-ray top view of thehandle arrangement 1 in which theupper housing 5 a is removed. The lockingclamp 3 comprises twopins 31, extending along the first axis A on both sides of the lockingclamp 3. The lockingclamp 3 is illustrated in the open position where the extendingpins 31 have been moved with the lockingclamp 3 along the axis B such that they are located in the second corner of thelower housing 5 b and under the flat 82 and interacting 84 portions of thespring 8. -
FIGS. 7a-7c illustrate the movement of thelink 7 as thehandle 2 moves between the open, intermediate, and closed states. InFIG. 7a , the handle is in the closed state and the lockingclamp 3 in the locking position. A first end of thelink 7 is rotatably connected to the lockingclamp 3 and a second end of thelink 7 is rotatably connected to theactuator 4. In the closed state of thehandle 2, the second end of thelink 7 is located with theactuator 4 on the second axis B and the first end of thelink 7 has been rotated around the second end away from the second axis B. - In
FIG. 7b , thehandle 2 has been moved into its intermediate position. When thehandle 2 is moved into the intermediate position, theactuator 4 is moved along the second axis B. The movement of theactuator 4 initiates a movement of second end of thelink 7 along the second axis B. As the second end is pulled along the second axis B, the first end rotates around the second end towards the second axis B. The rotation of the first end initiates the rotation of the lockingclamp 3 around the first axis A, from the locking position to the intermediate position. Since thelink 7 is arranged between theactuator 4 and the lockingclamp 3, a force lower than the resilient force of theflat springs 8 is exerted on the lockingclamp 3 when thehandle 2 is moved from the closed state to the intermediate state. Instead, the lockingclamp 3 rotates around first axis A. - Further movement of the
handle 2 into the open state moves the actuator further along the second axis B. Due to the force from theflat spring 8, a force greater than the resilient force is required to further move the lockingclamp 3 from the intermediate position to the open position. When a force greater than the resilient force is applied on theactuator 4, thelink 7 pulls on the end of the lockingclamp 3 to which it is rotatably connected and thereby pulls the lockingclamp 3 into the open position. Since no further rotation of the lockingclamp 3 is possible when in the intermediate position, further pulling force from theactuator 4 provides force on the lockingclamp 3 to exceed the resilient force and to move the locking clamp along second axis B to the open position. - As an alternative, or in addition to the previously disclosed features, a
handle arrangement 1 may comprise a locking means for engaging with a locking element on adoor frame 70, ahandle 2 arranged to move rotationally around a third axis C, between an open and a closed state, and which may comprise aconnection element 21. Thehandle arrangement 1 may further comprise anintermediate link 6 arranged between thehandle 2 and the locking means and for transforming the rotational movement of thehandle 2 to a substantially linear movement of the locking means. Thehandle 2 may be connected to theintermediate link 6 by theconnection element 21, and theintermediate link 6 may be arranged to perform a movement following an arcuate path when thehandle 2 is moved between the open state and the closed state. - The
intermediate link 6 may be arranged to be moved between an open state and a closed state, each corresponding to the open and closed states of the handle respectively. InFIG. 4a , theintermediate link 6 is illustrated in its closed state. - The
intermediate link 6 may comprise at least oneguide slot 61 arranged to receive theconnection element 21, as illustrated inFIG. 4 a. - The
connection element 21 is arranged to move along the at least oneguide slot 61 when thehandle 2 moves between the open and closed states. As illustrated inFIG. 4a , in the closed state of theintermediate link 6 and thehandle 2, theconnection element 21 is located at a first end of theguide slot 61. In the open state of theintermediate link 6 and thehandle 2, illustrated inFIG. 4b , theconnection element 21 has been moved along theguide slot 61 to a second end of theguide slot 61 as thehandle 2 has moved from the closed state to the open state. - The rotation of the
handle 2 may result in a rotational movement of theintermediate link 6 via the connection element's 21 interaction with theguide slot 61. Thehandle arrangement 1 may further comprise ahandle body 9, wherein thebody 9 comprises an arcedportion 91. The arcedportion 91 as illustrated for example inFIG. 2a , provides a pocket between thehandle 2 and thehandle body 9, such that rotation of thehandle 2 by hand or by other gripping means, is facilitated as an area for receiving for example fingers, for gripping thehandle 2 when moving this between its open or closed states, is provided. - The arcuate path of the
intermediate link 6 may correspond to the curvature of the arcedportion 91 of thehandle body 9. As illustrated inFIG. 4a , theintermediate link 6 is located on the arcedportion 91 of thehandle body 9 in the closed state. As thehandle 2 is moved to its open state, theintermediate link 6 follows its arcuate path corresponding to curvature of the arcedportion 91 into its open state position as illustrated inFIG. 4 b. - The arced
portion 91 of thehandle body 9 may further comprise aguide track 92 arranged to guide theintermediate link 6 along its arcuate path. Theguide track 92, illustrated inFIG. 2c , serves as a stabilizing guide when theintermediate link 6 is moved along its arcuate path as thehandle 2 is moved between the open and closed states. Theguide track 92 may be T-shaped. Theintermediate link 6 may comprise a groove correspondingly shaped as theguide track 92 and configured to receive theguide track 92. Theintermediate link 6 may be moveable along theguide track 92 and held in connection with thehandle body 9 by means of theguide track 92 and the groove. - The arcuate path may provide a rotation around a fourth axis D, wherein the fourth axis D is located in the cavity of the arced
portion 91 of thehandle body 9 as illustrated inFIG. 2b . The rotation along the arcuate path may in another embodiment be around an axis located outside the entire handle arrangement, due to a flatter arc in the arcuate path. - The locking means may comprise an
actuator 4 and a lockingclamp 3. An example ofsuch actuator 4 and lockingclamp 3 are illustrated inFIG. 4a . The connection between thehandle 2 and theintermediate link 6 and the rotational movement of these is transformed into a linear movement along axis B of theactuator 4 and the lockingclamp 3. - The
intermediate link 6 may be shaped in a V-shape, wherein a first flange of the V-shape may comprise an end rotatably connected to theactuator 4 and a second flange comprising theguide slot 61 for receiving theconnection element 21. The rotatable connection between theintermediate link 6 and theactuator 4 transforms the rotational movement of theintermediate link 6 to a linear movement of theactuator 4. The coupling between theguide slot 61 and theconnection element 21 translates the rotational movement of thehandle 2 around the third axis C into a rotational movement of theintermediate link 6 around the fourth axis D. - A bottom portion of the V-shape may comprise an arc shaped surface configured to face the arced
portion 91 of thehandle body 91. The arc shaped surface has a curvature corresponding to the curvature of the arcedportion 91 of thehandle body 9. - The
handle 2 may comprise alocking cylinder 22 and wherein the lockingcylinder 22 extends from thehandle 2 along a curvature of a circle with a radius corresponding to the length of thehandle 2. Theconnection element 21 may further be arranged on thelocking cylinder 22. The curvature of the lockingcylinder 22 facilitates the transformation of the handle's 2 rotation around the third axis C to the rotation of theintermediate link 6 around the fourth axis D. - The
connection element 21 may be formed as a pin extending into theguide slot 61 on theintermediate link 6. - The movement of the
handle 2 between its open and closed states, corresponds to an accelerated movement of theactuator 4, that is the distance moved on the second axis B by the actuator when thehandle 2 is moved between the open and closed states is larger than the distance the handle is moved. - The
handle arrangement 1 according either embodiments of the disclosed invention may further comprise a lock arranged on thelocking cylinder 22, which may be operated mechanically by for example a key or electrically. The lock may serve to lock thedoor 10 to which thehandle arrangement 1 is attached when the lockingclamp 3 is in its locking position and thehandle 2 is in its closed state such that the door cannot be opened unauthorized without a key or to prevent unintentional opening of the door. - In the drawings and specification, there have been disclosed preferred embodiments and examples of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for the purpose of limitation, the scope of the invention being set forth in the following claims.
