Definitions

  • Present invention relates to a locking device for first of all swinging arm assemblies for windows, but also for doors or shutters and where one and the same locking device permits a so called childproof lock and at least one or more airing positions, i.e. more or less partly open positions.
  • Swinging arm assemblies are especially used for windows where when the assemblies are mirror symmetrical and paired placed on the respective side of the window, between frame and casement.
  • the swinging arm assembly allows that the window can be pivoted approximately 180 grades, or at least near 180 grades, in a way that the outside of the window easily can be cleaned from within.
  • the respective swinging arm assembly usually consists of an outer assembly arm, whose lower end is articulately fastened near the center of the lateral part of the casement. The upper end is articulately attached with an upper swinging arm, which in turn is articulately attached in its lower part, to one in the frame fixed arranged frame plate, at its upper part.
  • the swinging arm assembly with some form of airing assembly that prevent an undesired closing of the window, while the same is subjected to for example wind pressure, negative pressure or draught. It is also a risk for injuries caused by squeezing if the window can be closed out of control.
  • a swinging arm assembly is provided with a childproof lock and a separate airing blocking device.
  • the childproof lock consists in that case of a plate with a lock recess in the shape of a guiding groove and a nose, which nose guides a holding element in the shape of a stop rivet into the groove and the groove has a rest position for the rivet in the closed position of the window and also a blocking position for the childproof lock of the window.
  • This solution has a separate airing blocking device in the shape of a foldable arm, which in the children blocked position is folded out and is clamped between the casement and the frame whereby the window is prevented from being unintentionally closed.
  • the Norwegian NO 320116 is further build on the childproof lock of the Swedish patent but differ from this by that here an additional, deep groove in the childproof lock is introduced together with the position of childproof blocking, whereby a fixed, locked position is obtained where the window is locked in both directions. In that way both the childproof lock and the airing blocking device is obtained with one and the same detail.
  • the handling of the blocking device can be slightly better if it were provided with for instance an extra long control handle or an extra control device in a favorable position, in such a way that the handling movement in one or another way is linked to the blocking device, but this implies a more costly and complicated construction that is more sensitive for clogging and dirt leading to that the mechanism seizes.
  • the airing blocking device is comprised of two details, a blocking arm together with a childproof lock, which is a disadvantage from the point of view of handling and the material.
  • the second solution indeed consists of one detail but has the disadvantage that it always is blocked in airing position, apart from if this is desired or not, resulting in that the blocking device must be handled to make it possible to close the window.
  • Another problem by existing blocking devices is that they do not securely engage when the casement is turned to a position for window cleaning.
  • the window has to be turned almost 180 grades, which can be difficult while there are no handles within reach in this position.
  • the blocking device in this position will block by its own weight in its blocking position, but often the blocking devices seizes depending on dirt and the like and the casement must principally be rotated to 180 grades relative its closed position to urge the blocking device in locking position.
  • older solutions exhibits lacks of resistance while for instance a deep groove, that constitutes the stop position, near the nose of the blocking device, impairs the resistance at the nose part, whereby the blocking device can be broken by a bigger load.
  • the aim is obtained to solve the above problems in the arrangement of the art that is mentioned in the preamble.
  • Earlier solutions that are mentioned above has a function of childproof block where a blocking hook/locking hook grips around a holding element, usually a stop rivet or the like.
  • the holding element is in those older solutions placed on one of the swinging arms, usually the lower one of the two swinging arms and by that it is possible to press the casement outwards relative the frame despite of the blocking position, because the swinging arm assembly itself is resilient by the swinging arms.
  • a much stronger so called childproof block or opening block is obtained by that the holding element is placed on the outer assembly arm of the swinging arm assembly.
  • the blocking device will be engaged with the holding element by that the holding element is guided into a lock recess, comprising a first end position for the rest position of the holding element and also a second end position arranged to a combined position/assignment for the childproof block and the airing block.
  • a blocking position is obtained between the frame plate that is fixed arranged in the frame and the outer assembly arm that is arranged in the casement, without long levers and without that the assembly will be resilient relative the blocking position.
  • the nearer the holding element is placed relative the attachment between the outer assembly arm and the casement the stronger the construction will be, resulting in a less possibility to resilience relative the blocking position.
  • the opening between the bottom piece of the casement and on the frame is not appreciably affected by the applied force whereby the safety margin the opening dimension in the blocked position related to demands and norms can be chosen otherwise.
  • a larger opening dimension can be allowed in the blocking or airing position, and/or that the freedom of choice of airing positions increases, i.e. more airing positions are allowed if it is desired.
  • the holding element is arranged on the casement and accordingly the blocking force is obtained between the frame plate that is fixed arranged in the frame and the casement, which gives a very strong and inelastic blocking.
  • the blocking device is articulately attached against the frame plate that is fixed arranged in the frame, between the points of attachment for the upper and lower swinging arms.
  • the blocking device will be lower situated in the construction and can so better be reached for handling, compared to older solutions where the blocking device is articulately attached around the upper point of attachment of the swinging arm against the frame plate.
  • the real, opening dimension between the bottom piece and the frame can be increased relative the opening dimension that is permitted by the norm, since the blocking device in that way grips lower on the outer assembly arm and by that also closer to its point of attachment against the casement implying that the lever that occurs between the holding element and the point of attachment against the casement will be shorter. Accordingly the placement is more favorable compared to older solutions where the blocking device is mounted around the upper point of attachment of the swinging arm and to difficult to reach.
  • the so called airing block that prevents the window from closing in an uncontrolled way, isn't in any way “automatic" disengageable in earlier solutions, but the block must in one or another way be handled to be disengaged.
  • this disadvantage is achieved by that the placement of the holding element together with the design of the assignment in the lock recess of the block in the second end position, which constitutes the combined position for the function of the childproof block and the function of the airing block, makes that the closing force, i.e. usually the hand force, that acts on the casement in a towards the frame inwards movement by the closing, always acts above the articulately attachment of the block.
  • the placement of the holding element and the design of the assignment at the blocking position makes that the angle, situated in the force direction, and between the tangent to the point of action of the closing force, its center of rotation, and the center of the holding element in its position in the blocking position, is greater than 90°, which results in that the closing force always acts above the center of rotation.
  • the blocking device automatically tries, by the closing movement, to be lifted from its blocking position and accordingly the blocking device can automatically be disengaged when a sufficient large force is applied inwards on the bottom piece of the casement.
  • an blocking device that can be automatic disengaged is obtained by that the assignment in the lock recess in the blocking device, in its second end position, which constitutes the combined position for the function of the childproof block and the function of the airing block, is made sufficient shallow, whereby the closing force, i.e. usually the hand force, that acts on the casement in a towards the frame inwards movement by the closing, always acts above the articulately attachment of the block.
  • the closing force i.e. usually the hand force
  • the holding element has a circular cross-section, where in that case the lateral dimension of the holding element in this case is the same as its diameter. Accordingly an airing block is obtained, which don't implies a totally fixed locked position but that is automatically disengaged when a sufficient force is applied inwards on the bottom piece of the casement. This eliminates the earlier mentioned disadvantages that exists in the older solutions, where one with a "two-handed grip" at the same time must disengage the blocking device and bring the casement inwards to close.
  • the second end position the combined position for the function of a childproof block and the function of an airing block has the shape of an open semicircle.
  • the holding element has a circular cross section, and the shape is preferable coordinated with the semicircle of the second end position.
  • the placement of the holding element and the semicircular shape of the second end position, where in addition the deepness of the second end position is slightly smaller than the diameter of the holding element, makes that the closing force, i.e. usually the hand force, that acts on the casement in a towards the frame inwards movement by the closing, always acts above the articulately attachment of the block, whereby an airing block is obtained that automatically can be disengaged.
  • the all in all design is however well tested so that an adequate airing block is obtained.
  • the locking device comprises a spring, mounted and clamped around the center of rotation of the blocking device.
  • the spring is arranged to urge the blocking device to locking by that the clamped spring force will rotate the blocking device in direction to the holding element, and when the holding element, by the movement of the casement, comes to the blocking position the blocking device snaps into the holding element and then partly surrounds the same.
  • a stop lug which is fixed arranged in the frame plate, and which stop lug limits the movement of the blocking device to act within a predetermined area.
  • the spring force also provides the advantage, compared to older solutions, that the blocking device locks earlier if the holding element in both the childproof position and the airing block position of the casement and in its reversed position, when the casement is rotated half a turn, for instance by window cleaning.
  • the spring choose how stiffly it has to be to close the window from its airing position by differently pre-stressing the spring.
  • a distinct snap sound can be heard when the blocking device reach a locked position around the holding element, which also facilitates for the user.
  • the combined blocking position (childproof block/airing block) don't allow for a appreciable resilience in the assembly itself, it is possible to choose a permitted opening dimension between the bottom piece of the casement and the frame, which is the same as or very close to the permitted, and not as in older solutions with a good margin to the permitted dimension.
  • This also opens the possibility to introduce several airing positions between the outer positions for closed and blocked position.
  • the block the lock recess hence comprises two or more assignments between the outermost combined position for the childproof block or the airing block and the innermost rest position for the holding element. Those assignments are as well as the outermost combined blocking position shallow, to allow for an automatic disengagement by closing or by opening to a larger desired grade of opening or to the childproof block position.
  • the blocking device is provided with a spring which acts to hold the block against the holding element in the different positions with a predetermined force, but it isn't necessary for the function.
  • the blocking device must in one or another way be disengaged from its blocking position at the same time as the casement is brought in a movement outwards relative the frame, whereby the holding element is allowed to leave the lock recess.
  • the blocking device comprises an actor, which preferable is a lever of optional length that is fixed arranged on the blocking device.
  • the actor is arranged to rotate, by an applied force, the blocking device in a way that the hook/nose is lifted, whereby the blocking device with its blocking assignment leaves the holding element.
  • the holding element leaves the lock recess and the casement can continue its movement outwards, either to a larger opening or to be rotated circa half a turn to reach, for instance, the position for window cleaning or the like.
  • the position for handling the blocking device has to be lower situated on the side of the frame, it is quite possible to move the actor further down along the frame and via linking devices move the movement at the actor to the blocking device. This can be desirable in some applications, such as handicap adapted applications and the like.
  • the locking device comprises a blocking device and more precise its lock recess, a first guide lug between the first end position/rest position for the holding element and the second end position/blocking position, which first guide lug is arranged to initiate a rotating movement of the blocking device when the casement with its blocking device moves towards the rest position, which is the closed position of the window.
  • a rotating rotary motion is initiated at the blocking device in upwards direction, relative the holding element and the window passes, by that the lock recess has an assigned first guide lug that lifts the blocking device, this first guide piece.
  • the rotary motion then continue by that the blocking device has a rounded side which is directed to the frame and when the blocking device is in contact with the frame the rotary motion by the blocking device continue until the rest position for the blocking device, and hence also for the holding element, is occupied.
  • This is advantageous compared to older solutions where the rotary motion is initiated only when the blocking device strikes the frame which increases the friction between assembly and frame leading to an increased wear.
  • the lock recess of the blocking device comprises a second guide lug between the first end position/rest position and the lower of the guiding surfaces to the lock recess.
  • This second guide lug is arranged to turn the blocking device so that the holding element, at its movement from the first end position/rest position to the second end position/blocking position, lands in the second end position/rest position.
  • the blocking device comprises stop side, below the lower guiding surface, i.e. below the opening or the lock recess.
  • the blocking device is in such a position that the guiding surfaces, that are situated on both sides of the opening of the lock recess, guides the holding element into the lock recess, whereby the combined childproof block or the airing block start to works according to earlier description.
  • the closing of the casement is prevented if the blocking device is fastened in vertical position, for instance owing to dirt or the like preferable at the articulately attachment of the blocking device.
  • the holding element lands on the stop side of the blocking device, i.e. below the lower guiding surface, it's impossible to completely close the window and hence the user is noticed about the problem and has the possibility to do something about the problem if it is possible.
  • This also means that if the window can be closed the blocking device works as is thought which gives an increased reliability.
  • the lock recess of the blocking device in an area in which the holding element can be introduced from the side, i.e. approximately perpendicular relative the area of distribution of the blocking device.
  • This is to also guarantee that the blocking device works if the window can be closed.
  • This additionally security works in a way that if the casement of some reason isn't centered in the frame by closing, and this implies that the holding element by its movement inwards to the blocking device, misses the blocking device laterally, i.e. passes beside the blocking device, the holding element will still be brought into the lock recess of the blocking device, but then mainly from the side, i.e. perpendicular inwards top the blocking device and the lock recess. In the almost closed or totally closed position of the casement, there is no other possibility for the blocking device as to enter the lock recess and so the blocking function works also in these cases.
  • the holding element comprises in a preferred form of execution a flanging at the free end of the holding element, the opposite end relative that end that is fixed arranged in the outer assembly arm. This flanging prevents the blocking device from sliding off the holding element in direction outwards to its free end.
  • the locking device comprises an additional blocking device, i.e. both the mirror symmetrical similar respective frame plate of the swinging arm assembly comprises a blocking device with corresponding holding element placed on respective outer assembly arm.
  • the placement of the holding element and corresponding blocking device, foremost vertically, is different on respective frame plate, whereby the advantage that the totally amount of blocking and airing positions is increased.
  • the amount isn't limited to one blocking device per completely window, nor one blocking device/one holding element per frame plate, but the amount blocking devices/holding elements can be increased as required.
  • both respective mirror symmetrical similar frame plates of the swinging arm assemblies comprises each a blocking device with corresponding holding element, but where the respective blocking device has different distances between its respective mounting point and the second end position/blocking position.
  • Figure 1a shows a section through a complete frame 1 which comprises a lower part 2, an upper part 3 and two lateral parts 4.
  • a casement 5 is pivotally suspended by means of two mirror symmetrical similar swinging arm assemblies 6 each comprising one outer assembly arm 7, whose lower part is articulately attached, with a pivot pin 25, to the casement 5, near the center of the lateral part of the casement.
  • the swinging arm assembly 6 comprises an upper swinging arm 8 which in its upper end is articulately attached at the upper end of the outer assembly arm 7.
  • the lower end of the upper swinging arm 8 is also articulately attached to a frame plate 9 that is fixed arranged in the frame.
  • the swinging arm assembly 6 also comprises a lower swinging arm 10 which also is articulately attached at the upper end of the outer assembly arm 7, but below the upper attachment of the swinging arm 8.

Between the points of attachment of the swinging arms to the frame plate 9 a blocking device 11 is articulately attached and preferable the point of attachment is placed slightly closer to the lower attachment of the swinging arm 10.
  • a holding element 13 is arranged, preferably below the center of the outer assembly arm 7. This holding element is preferable a stop rivet or the like and the blocking device 11 is arranged to grip around the holding element 13.
  • the window is in a position where the blocking device 11 is not in engagement with the holding element 13 but opened to a larger grade of opening.

  • Figure 1b shows the frame 1 with the casement 5 in its blocked position, which is a combined position for childproof blocking and airing.

  • the assignment/the second end position 16 can itself also be provided with lateral edges with some inclination instead of as according to the figure b in the shape of a approximate half circular arc.
  • the opposite side relative the shallow edge, the side that is directed towards the guiding surfaces 14, is provided with a high edge that constitutes a "nose" or a hook.
  • the blocking device 11 also comprises a recess 27 for an articulately mounted attachment to the frame plate 9 and the actor 18, arranged to handle the blocking device 11 by pressing towards the casement 5, whereby the blocking device 11 is disengaged relative the holding element 13, and the blocking function is disengaged.
  • Fig 2c shows the holding element 13 in detail.
  • the holding element 13 is preferable a stop rivet with a flanging 33 at its outer, free end.
  • the holding element is in its second end fixed arranged on the outer assembly arm 7, preferable on its lower half.
  • the lateral dimension H of the holding element is preferable larger than the deepness D of the second end position and moreover the length of the holding element 13 must be slightly larger than the thickness of the blocking device 11, to permit that the blocking device will grip the holding element 13.
  • the closed position of the window is initiated by opening the movement of the casement outwards, relative the frame 1, after disengagement of the locking by means of the handle of the window (not shown).
  • the movement of the holding element 13 is initiated from the first end position 15 in direction towards the second end position 16, whereby the holding element slides along either of the two sliding surfaces to thereafter reach the second end position 16, which is the combined position for childproof block and airing block.
  • the blocking device 11 is spring loaded, via the spring 17, the blocking device tries to be in engagement with the holding element 13 which in that way occupies the second end position 16.
  • a secure function of the childproof block is hence obtained because the movement of the casement 5 is now prevented to continue its upward directed movement.
  • the spring 17 improves the function and gives a distinct snapping loud by a correct blocking position, but the blocking function also works without the spring depending on mounting and guiding by the shape of the lock recess. If one wish to continue the movement of the casement 5 outwards to open the window further, the blocking device 11 must be disengaged from the holding element 13 by means of the actor 18, which then is pressed in direction towards the casement, whereby the blocking device 11 is lifted by the holding element and the casement can be pressed outwards.
  • the spring loaded blocking device 11 is in this position arranged and in a position to automatic guide the holding element 13 into the lock recess 12, when the blocking device and holding element is in contact with each other.
  • the blocking device 11 snaps, because of the spring 17, down to the holding element 13 and engages around the same and the holding element 13 is hereby in the second end position 16.
  • the second end position 16 is shallow at the side that holds against the force, which is described above.
  • the spring force is clamped to a tested force for adapting it to a selectable inert resistance.
  • the rotary motion of the blocking device is provided by a combination of the guiding in the lock recess and in the later part of the rotary motion, the rounded outside of the blocking device 11, which touch the frame and assist to complete the rotary motion.
  • the combined position for childproof block and airing the airing function is active insofar that either only via the assignment itself or in combination with the spring 17 there is an opposite directed force making the movement of the casement 5 inwards to the frame 1 more difficult.
  • This force is adjustable by means of the spring 17 and since the assignment is shallow the airing block can be automatic disengaged, only by overcome the opposite directed force, in contrast to other solutions, which is an obvious user friendly function.
  • the blocking device 11 If by one or another reason the blocking device 11 isn't in the right position by closing the window, for instance depending on dirt, so that the blocking device 11 seizes, and the blocking device thereby is in a vertical position the holding element 13 will, at the closing movement of the casement, hit a stop side 31 on the blocking device 11, below the opening to the lock recess 12 and in that case the window cannot be completely closed. In this way it is indicated that the blocking device doesn't work fully, which in this way makes that it will be self regulating for the user to control that the childproof block works. Hence there is an extra security that indicates if the window can be closed then the childproof block works.
