Description

Electrical striker unit Technical fieldThe present disclo sure relates to an electrical striker unit, and in particular an electricalstriker unit provided with a link arrangement enabling movement of a pivot latch irrespectively that the pivot latch is subjected to external pressure.
Background To reduce energy lo sses in door environments, sealing strips are used between door anddoor frame. These sealing strips tend to become larger and larger to rninimize the flow ofheat in the gap between door and door frame. This also results in the door being pressedagainst the door frame, thus causing the door lock to be pressed against the pivot latch ofthe electrical striker unit in the door frame. lf an electrical striker unit that is not intendedfor such load is used in the door frame, it will result in a downtime and the door cannot beopened with e. g. automatics. The reason is that with increased mechanical pressure fromthe door, the frictional forces on the arm linkage within the electrical striker unit alsoincrease, which means that the electromechanical unit, e. g. solenoid, is unable to providethe necessary movement in order to release the pivot latch.
List pressure may also occur if the door is incorrectly mounted or if gravel or stone fallsbetween the door and the door frame, even pressure differences on the inside and outside of the door give rise to this type of problem.
EP-2582899 relates to a locking device comprising rotating links and guide with slidingelement. The locking device comprises a locking mechanism arranged to move at least onelocking element between a locked state, and an unlocked state, which locking mechanismis adapted to be connected with and to receive the motion for the movement from an operating mechanism arranged to control and to provide the motion for the movement.
Still, a problem to be solved is to be able to change state from a locked state to an open state even if the pivot latch is subjected to pressure.
Thus, one object of the present invention is to achieve an electrical striker unit that eliminates, or at least rnitigates, the above problem.
Summary The above-mentioned object is achieved by the present invention according to the independent claim.
Preferred embodiments are set forth in the dependent claims.
The present invention relates to aspects of an electrical striker unit comprising a housingenclo sing parts of the unit. The electrical striker unit is configured to be mounted in a doorframe such that it cooperates with a lock assembly mounted at a door leaf, and comprises apivot latch being pivotable between a locked position and an open position. The electricalstriker unit is configured to be in two different states, a locked state when the pivot latch isin the locked position and the pivot latch cooperates with the lock assembly mounted atthe door leaf such that the door is closed, and in an open state when the pivot latch is inthe open position and pivoted into the housing, and it may be possible to open the door.The striker unit further comprises an arm linkage arrangement providing an operationallinkage between an electromechanical unit and the pivot latch, wherein theelectromechanical unit is configured to generate translational movement along alongitudinal movement rod to set the end point of the movement rod in two positions, afirst position Pl and a second position P2. The arm linkage arrangement is structured toreceive said translational movement and to transfer the movement such that it facilitatesboth securely fiXation of the pivot latch in the locked position and movement of the pivotlatch from the locked position to the open position, in dependence of the translationalmovement of the movement rod between the first position Pl and the second position P2.The arm linkage arrangement comprises a first arm, a second arm, and a blocking arm, andthat -the first arm is pivotably fixed relative the electrical striker unit in a first pivot point, andcomprises a first part and a second part eXtending in different directions from the firstpivot point, the first part is structured to bear on the pivot latch in a point A such that, when in a locked state, the pivot latch is in the locked position, -the second arm is pivotably fixed relative the electrical striker unit in a second pivotpoint, and comprises a first part and a second part extending in different directions fromthe second pivot point, the first part of the second arm is structured to bear on the secondpart of the first arm in a point B, -the blocking arm is pivotably fixed relative the electrical striker unit in a third pivot point,the blocking arm is movable between two positions, a blocking position in which ablocking part of the blocking arm prevents the second part of the second arm to move andthereby secure that the pivot latch is in its locked position, and an opening position, inwhich position the second arm is free to move into a position allowing the pivot latch to bein its open position, wherein a part of the blocking part of the blocking arm to bear againstthe second part of the second arm is provided with a low friction member to rninimize thefriction in relation to the second part of the second arm when moving the blocking armfrom its blocking position to its opening position and thereby enabling the second arm to easily move into a position allowing the pivot latch to be in its open position.
The compact leverage system provided by the first and second arms facilitates a high forceratio exchange between the blocking arm and the pivot latch in relation to the limitedavailable space of the electrical striker unit housing. The high force ratio exchange isimportant in that the force exerted on the blocking arm by the second arm thereby isreduced. The advantage achieved by the compact leverage system is further improved byproviding a low friction member on the blocking part of the blocking arm that bear against the second part of the second arm.

Detailed description The electrical striker unit will now be described in detail with references to the appendedfigures. Throughout the figures the same, or similar, items have the same reference signs.Moreover, the items and the figures are not necessarily to scale, emphasis instead beingplaced upon illustrating the principles of the invention. For sake of clarity not all items areindicated in all figures. Each of figures 7-12 include three views of the electrical strikerunit, two side views and one perspective view. All three views of one figure show theelectrical striker unit working in the same operational mode and the same activation state of the electromechanical unit.
The present invention relates to an electrical striker unit 2 comprising a housing enclo singparts of the unit, the electrical striker unit is configured to be mounted in a door frame such that it cooperates with a lock assembly mounted at a door leaf.
Figures 1-6 illustrates various views of different parts of the electrical striker unit, figures7-9 illustrates various views of the electrical striker unit when Working in a so -called fail-safe operational mode, and figures 10-12 illustrates various views of the electrical strikerunit when working in a so-called fail- secure operational mode. These two operational modes will be further discussed below.
The electrical striker unit comprises a pivot latch 4 being pivotable between a lockedposition and an open position, the electrical striker unit is configured to be in two differentstates, a locked state when the pivot latch 4 is in the locked position and the pivot latch 4cooperates with the lock assembly mounted at the door leaf such that the door is closed,and in an open state when the pivot latch 4 is in the open position and pivoted into the housing, and it may be possible to open the door.
The electrical striker unit is configured to work in two different operational modes, onefail- safe mode illustrated in figures 7-9, and one fail- secure mode illustrated in figures 10-12. The operational modes differ in that in the fail- safe mode the electrical striker unit is inits open state when the electromechanical unit not is activated and in its closed state whenthe electromechanical unit is activated. The opposite applies in the fail-secure mode,where the electrical striker unit is in its closed state when the electromechanical unit not isactivated and in its open state when the electromechanical unit is activated. The twomodes may be achieved with an electrical striker unit that only differs with regard to thatdifferent versions of the fifth arm is used and where this arm is attached to the fourth arm.This is advantageous in that no other adaptations of the striker unit may be made in order to have it working in these two operational modes.
With references to figures 7-12, the striker unit 2 further comprises an arm linkagearrangement providing an operational linkage between an electromechanical unit 6 and the pivot latch 4, wherein the electromechanical unit 6 is configured to generate translational 6 movement along a 1ongitudina1 movement rod 8 to set the end point 10 of the movementrod in two positions, a first position P1 and a second position P2. See figures 7, 9, 10, and 12.
The arm 1inkage arrangement is structured to receive the trans1ationa1 movement and totransfer the movement such that it faci1itates both secure1y fiXation of the pivot 1atch 4 inthe 1ocked position and movement of the pivot 1atch 4 from the 1ocked position to the openposition, in dependence of the trans1ationa1 movement of the movement rod 8 between thefirst position P1 and the second position P2. In the i11ustrated version of thee1ectromechanica1 unit 6 the first position P1 prevai1s when the e1ectromechanica1 unit notis activated and the second position P2 prevai1s when the e1ectromechanica1 unit isactivated, i.e. when the e1ectromechanica1 unit is activated the movement rod is moved a short distance into the unit (to the 1eft in the figures).
The arm 1inkage arrangement comprises a first arm 12, a second arm 14, and a blockingarm 16. In addition the arm 1inkage arrangement comprises a fourth arm 36 and a fifth arm 38 that wi11 be discussed further down.
The first arm 12 is i11ustrated in figure 1 and is pivotab1y fixed re1ative the e1ectrica1striker unit 2 in a first pivot point 18, and comprises a first part 20 and a second part 22eXtending in different directions from the first pivot point 18. The first part 20 is structuredto bear on the pivot 1atch 4 in a point A such that, when in a 1ocked state, the pivot 1atch isin the 1ocked position. Thus, the first arm 12 is configured to move about an aX1e through the first pivot point 18.
The second arm 14 is i11ustrated in figure 2 and is pivotab1y fixed re1ative the e1ectrica1striker unit 2 in a second pivot point 24, and comprises a first part 26 and a second part 28eXtending in different directions from the second pivot point 24. Thus, the second arm 14is configured to move about an aX1e through the second pivot point 24. The direction ofthe aX1e through the first pivot point is essentia11y perpendicu1ar to the direction of the aX1ethrough the second pivot point. As indicated in figure 2 the aX1e through the second pivotpoint 24 is s1ight1y ang1ed and has an ang1e of 1ess than 90 degree, preferab1y in the 7 interva1 of 85-90 degrees, and e. g. 88 degrees as indicated in the figure. The first part 26of the second arm 14 is structured to bear on the second part 22 of the first arm 12 in apoint B. Preferab1y, the surfaces on each of the first and second arms that bear againsteach other are adapted to each other, e. g. being essentia11y para11e1 and being beve1ed, i.e. ang1ed in order to achieve the high force ratio exchange.
The blocking arm 16 is i11ustrated in figure 3 and is pivotab1y fixed re1ative the e1ectrica1striker unit in a third pivot point 30. The b1ocking arm is configured to move about an aX1ethrough the third pivot point 30, which aX1e is essentia11y para11e1 to the aX1e of the secondpivot point. The b1ocking arm 16 is movab1e between two positions, a b1ocking position inwhich a b1ocking part 32 of the b1ocking arm 16 prevents the second part 28 of the secondarm 14 to move and thereby secure that the pivot 1atch 4 is in its 1ocked position, and anopening position, in which position the second arm 14 is free to move into a positiona11owing the pivot 1atch 4 to be in its open position. In figures 7, 8 (fail-safe mode) and 11,12 (fai1- secure mode) the b1ocking arm 16 is in its opening position, and in figures 9 (fai1- safe mode) and 10 (fai1-secure mode) the b1ocking arm 16 is in its b1ocking position.
A part of the b1ocking part 32 of the b1ocking arm 16 to bear against the second part of thesecond arm is provided with a 1ow friction member 34 to n1inin1ize the friction in re1ationto the second part 22 of the second arm 16 when moving the b1ocking arm 16 from itsblocking position to its opening position and thereby enab1ing the second arm 14 to easily move into a position a11owing the pivot 1atch 4 to be in its open position.
According to one embodiment of the e1ectrica1 striker unit 2 the 1ow friction member 34 isa ba11-bearing member. As an a1ternative, the 1ow friction member 34 may be a 1owfriction materia1 app1ied to the surface of the b1ocking part 32, e. g. Teflon, or any sin1i1ar materia1.
According to another embodiment the b1ocking arm 16 is U-shaped and the 1ower part ofthe U constitutes the blocking part 32 and is structured to bear against the second part 28of the second arm 14 in a point C, via the 1ow friction member 34, when the blocking arm 16 is in the b1ocking position. In figure 3 a perspective view of the b1ocking arm 16 is 8 illustrated provided with a low friction member 34 being a ball-bearing member. The lowfriction member 34 may be realized in many different ways. For example, it may comprisea tube being a cylinder having a circular cross-section arranged on a rod such that the cylinder easily may rotate in relation to the rod.
The first and second arms 12, 14 together constitute a compact leverage system betweenthe pivot latch 4 and the blocking arm 16. In one embodiment the first arm 12 is structuredsuch that the distance between point B and the first pivot point 18 is at least twice as thedistance between point A and the first pivot point 18. This is illustrated in figure 1 wheretwo views of the first arm is shown. The second arm 14 is structured such that the distancebetween point C and the second pivot point 24 is at least twice as the distance betweenpoint B and the second pivot point 24. This is illustrated in figure 2 where various viewsof the second arm is shown. The cross-sectional view to the right in the figure is a viewalong line A-A in the view to the left in figure 2. The compact leverage system providedby the first and second arms facilitates a high force ratio exchange between the blockingarm and the pivot latch in relation to the lin1ited available space of the electrical strikerunit housing. The high force ratio exchange is important in that the force exerted on the blocking arm by the second arm thereby is reduced.
According to still another embodiment the blocking member 16 is movable between theblocking position and the opening position in dependence of movement of the movementrod 8. The movement of the movement rod 8 is transferred to the blocking arm 16 via afourth arm 36 and a fifth arm 38. The fourth arm is illustrated in figure 4, and the fifth arm is available in two versions which are illustrated in figure 5 and 6.
The fifth arm 38 is elongated and comprises a first end 40 that is connected to the movement rod 8 and a second end 42 that is pivotably connected to the fourth arm 36.
In a further embodiment the fourth arm 36 is pivotably fixed relative the electrical strikerunit in a fourth pivot point 44, and is pivotable between two positions, a first position where the fourth arm 36 has moved the blocking arm 16 such that it is fixed in its blocking 9 position (see figures 9 and 10) and a second position where the fourth arm 36 has moved the blocking arm 16 to its opening position (see figures 7, 8, 11, 12).
In one embodiment with references to figure 4, the fourth arm 36 is provided with anengagement slot 46 that is structured to cooperate with an engagement pin 48 provided atthe blocking arm 16 (see figure 3), such that when the fourth arm 36 pivots between thefirst and second positions the engagement pin 48 is forced to move along the engagement slot 46 and thereby provide movement to the blocking arm 16.
In another embodiment the fifth arm 38 is available in two different versions, i.e.structural shapes, a first shape and a second shape, which are shown in figures 5 and 6,respectively. The first shape is configured to be pivotably connected to the fourth arm 36in a first connection point 54 of said fourth arm 36, which is illustrated in figures 7-9. Thesecond shape 52 is configured to be pivotably connected to the fourth arm 36 in a secondconnection point 56 of said fourth arm 36, which is illustrated in figures 10-12. The firstand second connections points are arranged at opposite sides of the fourth pivot point 44,see figure 4. Thereby the two different operational modes of operation of the electricalstriker unit may be applied in dependent upon which of the two different structural shapes of the fifth arms that is used.
Thus, the fifth arm is available in two different shapes, the first shape and the secondshape.
The first shape is illustrated in figure 5 and the electrical striker unit provided with the firstshape 50 of the fifth arm is shown in figures 7-9. The electrical striker unit then works inthe so-called fail-safe mode, which means that the striker unit is in a locked state whenactivation voltage is applied to the electromechanical unit (see figure 9). When noactivation is applied to the electromechanical unit the striker unit is in its open state (seefigures 7 and 8). In figure 7 the pivot latch is in its closed position but may easily move toits open position which is illustrated in figure 8, see e. g. the different positions of the first and second arms in figures 7 and 8.
The second shape is illustrated in figure 6 and the electrical striker unit provided with thesecond shape of the fifth arm is shown in figures 10-12. The electrical striker unit thenworks in the so-called fail-secure mode, which means that the striker unit is in a lockedstate when no activation voltage is applied to the electromechanical unit (see figure 10).When activation is applied to the electromechanical unit the striker unit is in its open state(see figures 11 and 12). ln figure 11 the pivot latch is in its closed position but may easilymove to its open position which is illustrated in figure 12, see e. g. the different positions of the first and second arms in figures 11 and 12.
Thus, the fourth arm will rotate in different directions depending on which of the twoshapes of the fifth arm that is applied, in dependence of the same longitudinal movementof the movement rod. This facilitates that both fail- safe and fail-secure operational modesof the electric striker unit easily may be achieved by choosing the one of the two shapes of the fifth arm that is related to the desired mode.
Thus, the movement of the pivot latch is indirectly and electromagnetically controlled bythe electromechanical unit provided in the electrical striker unit.To open a closed door the electrical striker unit may be remotely controlled by e. g. pressing an open button.
The present invention is not limited to the above-described preferred embodiments.Various alternatives, modifications and equivalents may be used. Therefore, the aboveembodiments should not be taken as limiting the scope of the invention, which is defined by the appending claims.
