Description
- The present invention relates to an anti-slam device for a tilt window.
- A tilt window is a window with a fixed frame and a leaf which is hingeably attached to the fixed frame.
- In a tilt window the leaf can hinge around an imaginary horizontal tilt axis at the underside of the window until a certain opening appears at the top called the tilt position which is used for short-term or long-term ventilation.
- To hold the leaf in its tilt position it is customary to apply a scissor mechanism which is mounted at the top between the fixed frame and the leaf and which limits opening the leaf around the imaginary tilt axis to a certain open tilt position.
- Such scissor mechanism is typically composed of a long arm and a short arm which are hingeably connected.
- The long arm is hingeably connected via a frame section to the fixed frame with a first end and with the other second end is slideably and hingeably connected to the leaf via a leaf section.
- The short arm is hingeably connected to the long arm with one end in a central point between the ends of the long arm and with its other end is hingeably connected to the leaf section.
- In a closed window the scissor mechanism is closed and concealed in the rebate between the fixed frame and the leaf, whereby the arms are parallel to each other.
- On tilting open the window, the arms rotate open whereby the hinge on the second end of the long arm moves into a slotted hole in the leaf section up against the end of the slotted hole.
- Thus, the scissor mechanism functions as a restrictor which stops the window falling open on tilting, which is important in terms of safety. The weight of the leaf helps to hold open the leaf.
- However, tilt windows may also have the tendency to unintentionally fall shut again from the tilt position, for example by underpressure resulting from an accidental gust of wind.
- That is why typically such scissor mechanisms are provided with an anti-slam device as a standard practice. This is a kind of clip which is mounted on the first end of the long arm and which holds the leaf with a certain resistance in the open tilt position, but which must not have too much resistance either so that when you want to shut the leaf again, the operation is still somewhat flexible and comfortable without needing too much force.
-
DE10013697A1 describes a locking means for a turn and tilt window, the locking means 26 comprising a spring force applied to aclamping member 30. Other related background art can be found inDE8023717U1 ,DE2451556A1 ,DE4313610A1 ,EP2495380A2 ,DE7632457U1 andDE7634928U1 . - However, there are certain trends in the windows market, more specifically that:
- leaf profiles are becoming increasingly thicker depthwise for a higher thermal performance;
- windows are becoming increasingly higher; and,
- increasingly, triple glass is being used in the leaf.
- Each of these trends causes the centre of gravity of the leaf to be increasingly closer against the vertical plane through the imaginary tilt axis, such that the weight of the leaf is increasingly unhelpful to hold open the leaf and consequently the leaf will fall shut more easily in the event of a gust of wind or the like.
- However, providing a stronger anti slam device as a standard practice is not a solution because then operating, for example, less high windows becomes too hard.
- The invention relates to an anti-slam device which can be applied additionally or alone and preferably can be mounted later on. It can be provided for high windows or applied in the event of problems.
- To this end, the invention relates to an anti-slam device for offering resistance against the slamming shut of a tilt window which is held in its opened tilt position by means of a scissor mechanism, whereby the anti-slam device is intended for mounting on the scissor mechanism with mutually rotatable parts which in the opened tilt position of the scissor mechanism mutually enclose an angle and which in the closed condition of the scissor mechanism lie parallel or practically parallel to each other, whereby the anti-slam device contains an elastic element and a plate-shaped or other element with a side for attaching the anti-slam device to the scissor mechanism, whereby the elastic element contains a cam-shaped part or cam which in its resting position protrudes from the plate-shaped or other element and whereby the elastic element has a certain resistance against pushing the cam of the elastic element out of said resting position, whereby the anti-slam device in a mounted condition is attached with its plate-shaped or other element to one of said mutually rotatable parts in such a way that the cam in the open tilt position of the scissor mechanism clicks behind one of the other mutually rotatable parts in a position whereby the cam when closing the scissor mechanism is pushed out of this clicked condition by the mutual rotation, whereby the elastic element is made with a longitudinal elastic body on which said cam is mounted and which is enclosed in two seats of the plate-shaped element which are located in each other's extension, whereby said cam is mounted between both seats and whereby the seats are such that they allow an elastic stretch of the body in longitudinal direction but prevent a rotation thereof in the seats.
- An anti-slam device according to the invention is intended to be attached with its plate-shaped element to one of the constituent parts of the scissor mechanism or to be part of it such that the cam of the elastic element on opening the scissor mechanism is located in the trajectory of one of the other constituent parts of the scissor mechanism and hooks behind it when or before the open tilt position of the scissor mechanism is reached.
- Because the cam of the elastic element hooks into the open position to lock the scissor mechanism in this position, this results in an extra resistance against the tilt window slamming shut because first the elastic resistance of the hooked elastic element needs to be overcome.
- Preferably, the anti-slam device is glued to the scissor mechanism and to this end is for example provided with double-sided tape on its plate-shaped section which is covered with a removable film that needs to be removed at the time the anti-slam device needs to be glued to the scissor mechanism.
- In this way the anti-slam device can be easily mounted on a scissor mechanism of an existing tilt window or as an extra anti slam device in the event of a high window and when this appears to be necessary.
- In this way a classic scissor mechanism can be used for both low and high windows and in the case of a high window an additional anti slam device can be attached to the scissor mechanism.
- Preferably the anti-slam device is mounted on the long arm with the cam in the trajectory of the rotational movement of the short arm relative to the long arm when tilting open the tilt window.
- Preferably, the cam is executed as a triangle which points down and which in the closed condition of the scissor mechanism is located next to and at a distance of a side edge of the short arm.
- Thus, the resistance to be overcome on initiating tilting open the tilt window is limited because the short arm on tilting open at an angle comes into contact with a slanted side of the cam such that the required force to push up the cam from its resting position into the closed condition of the tilt window is less.
- The invention also relates to a scissor mechanism provided with an anti-slam device according to the invention and a tilt window equipped with such mechanism.
- The invention also relates to the use of an anti-slam device according to the invention for offering resistance against the slamming shut of a tilt window which is held in its opened tilt position by means of a scissor mechanism.
- With the intention of better showing the characteristics of the invention, a preferred embodiment of an anti-slam device according to the invention applied to the scissor mechanism of a tilt window is described hereinafter, by way of an example without any limiting nature, with reference to the accompanying drawings wherein:

figure 3 shows a perspective view of the scissor mechanism indicated infigure 2 by F3; -
figure 4 shows the anti-slam device according to the invention indicated infigure 3 with F4 on a larger scale; -
figure 5 shows a bottom view according to arrow F5 of the anti-slam device infigure 4 ; -
figure 6 shows the anti-slam device of thefigures 4 and 5 in an exploded view; -
figure 7 shows a cross-section according to line VII-VII infigure 4 ; -
figure 8 shows the scissor mechanism offigure 3 but shown in three different positions; -
figure 9 shows a local cross-section according to line IX-IX infigure 8 ; -
figure 10 shows the local cross-section offigure 9 but in the start position of tilting open the tilt window. - The tilt window 1 shown in
figure 1 consists of afixed frame 2 and aleaf 3 which is hingeably attached at the bottom in theframe 2 around an imaginaryhorizontal tilt axis 4. - A
scissor mechanism 5 is mounted between thefixed frame 2 and theleaf 3 which restricts the maximum tilting angle over which theleaf 3 can be tilted open as in the case offigure 1 . - A classic scissor mechanism by way of example is shown in
figure 3 . - As shown in more detail as appears from this
figure 3 , thescissor mechanism 5 is composed in the known way of aframe section 6 for attaching on thefixed frame 2; aleaf section 7 for attaching on theleaf 3; along arm 8 which with a first end 9 is rotatably connected to theframe section 6, in this case by means of adouble link 10, and with the othersecond end 11 is slideably and hingeably connected to theleaf section 7, in this case by means of ahinge pin 12 which engages in aslotted hole 13 of theleaf section 7, and ashort arm 14 which is hingeably connected with one end 15 to thelong arm 8 with ahinge pin 16 between the first and the second end of thelong arm 8 and which with its other end is hingeably connected to theleaf section 7. - The rotatable connection between the
long arm 8 and theframe section 6 can also occur in other forms than by means of adouble link 10, for example directly or by means of more than 2 arms. - The combined slide and hinge connection between the
long arm 8 and theleaf section 7 can also be realised in other ways than by means of ahinge pin 12 and slottedhole 13. - Typically, a
scissor mechanism 5 is always provided with aframe section 6, aleaf section 7 and along arm 8 and ashort arm 14 in between which is hingeable relative to thelong arm 8 when opening and shutting the tilt window 1. - The
long arm 8, theshort arm 14 and theleaf section 7 are rotatably connected and are jointly called the mutuallyrotatable parts - On the leaf side the
scissor mechanism 5 can be provided with an anti-slam device not shown here. - Specific to the invention is that the
scissor mechanism 5 is provided with ananti-slam device 18 as shown in thefigures 4 to 7 which in this case is glued to thelong arm 8 as shown infigure 3 for offering resistance against the tilt window 1 slamming shut. - The anti-slam device contains a plate-
shaped element 19 with aside edge 20 and anunderside 21 which is provided with a self-adhesive layer ofglue 22 or double-sided tape to be able to attach theanti-slam device 18 to thescissor mechanism 5. In unmounted condition, the layer of glue can be provided with aremovable film 23. - The
anti-slam device 18 also contains anelastic element 24 which is mounted next to and along theside edge 20 and is connected to the plate-shaped element 19 and which contains a cam or cam-shaped part 25 which in its resting position protrudes downward under theunderside 21 of the plate-shaped element 19, whereby the assembly is such that thecam 25 can be elastically pushed upward by an upward force in a direction perpendicular to theunderside 21 of the plate-shaped element 19. - Preferably, the elastic element is made entirely of an elastic material such as polyamide.
- In the example of the figures the
elastic element 24 is made with a longitudinalelastic body 26 on which saidcam 25 is mounted and which is enclosed in twoseats 27 of the plate-shaped element 19 along saidside edge 20, whereby saidcam 25 is mounted between bothseats 27 and whereby theseats 27 are such that they allow an elastic stretch of thebody 26 in longitudinal direction X-X' but prevent a rotation thereof in theseats 27. - To this end the longitudinal
elastic body 24 is in this case made for example as a flat strip and each of theseats 27 is formed by a U-shaped bracket withlegs 27a and 27b between which the longitudinalelastic body 24 is enclosed. - The
legs 27a and 27b of the U-shapedbracket 27 extend parallel or practically parallel with theunderside 21 of the plate-shaped element 19 and the opening 27c of the U-shapedbracket 27 faces the plate-shaped element 19. - The plate-
shaped element 19 is made for example of a metal stainless steel plate or the like and theseats 27 are for example formed by double-folding the plate at a right angle. - The
elastic element 24 can for example be slid along theopenings 27c laterally in theseats 27 and thereafter be secured against lateral removal and rotation by providing thelongitudinal body 26 on the level of thebrackets 27 with an undercut or aslot 28 and folding at least oneleg 27b of thebrackets 27 into the undercut or theslot 28 as shown infigure 7 . - The brackets are connected by a downward facing
collar 29 to the plate-shapedelement 19, saidcollar 29 being able to serve during mounting to align theanti-slam device 18 against aside edge 30 of thelong arm 8. - To secure the
longitudinal body 26 in longitudinal direction X-X' in theseats 27, saidlongitudinal body 26 is made thinner for example in the sections 26a on the level of theseats 27 than in the sections outside theseats 27, respectively in thecentral section 26b and at theends 26c. - Preferably, the
cam 25 is made as a triangle which with its base 25a is attached or connected to thecentral section 26b of thelongitudinal body 26 and which possesses ashort side 25b and along side 25c which together enclose an angle facing away from theunderside 21 of the plate-shapedelement 19. - The
cam 25 is mounted with its base 25a eccentrically from thecentral section 26b and extends from oneseat 27 on the side of thelong side 25c up to a distance from theother seat 27 on the side of theshort side 25b, said distance in the example being approximately equal to half the length of thecentral section 26b. - The base 25a and the
long side 25c enclose an angle B between 15 and 20°, preferably an angle B of approximately 18°. - The base 25a and the
short side 25b enclose an angle A of approximately 70°. - In the example, the
anti-slam device 18 is attached to thelong arm 8 as shown infigure 3 with thecollar 29 against theside edge 30 of thelong arm 8 and in such a way that thecam 25 hooks with itsshort side 25b behind the side edge 14a of theshort arm 14 facing the first end 9 when thescissor mechanism 5 is opened to its maximum tilt position, whereby thecam 25 with its angle B between the base 25a and thelong side 25c faces the first end 9 of thelong arm 8. - If mounted in this way, the
elastic element 24 extends in its longitudinal direction along theside edge 30 and on opening and shutting thescissor mechanism 5, thecam 25 is located in the trajectory of theshort arm 14 which on opening and shutting thescissor mechanism 5 relative to thelong arm 8 rotates around thehinge pin 16 and in the closed condition of thescissor mechanism 5 thecam 25 falls next to the opposite side edge 14b of theshort arm 14 and at a lateral distance D thereof as shown infigure 9 . - The operation of the anti-slam device is very simple and is illustrated by
figure 8 which shows three supposed positions of thescissor mechanism 5, i.e. a closed position I; an open position III and a position II located in between corresponding respectively with a closed tilt window, a tilt window opened as far as possible and an intermediate position of the tilt window. - In the closed position I the short arm is located at a distance D from the
cam 25 as shown in the bottom view of the correspondingfigure 9 . - When the
scissor mechanism 5 is opened, the side edge 14b of theshort arm 14 comes into contact with thelong side 25c of thecam 25 as shown infigure 10 . - On opening it further the
short arm 14 pushes up thecam 25, as shown in the intermediate position II infigure 8 , up to when thecam 25 hooks with itsshort side 25b behind theshort arm 14 as shown in the position III offigure 8 , corresponding with the opened position offigure 3 . - Consequently, the open tilt position of the
scissor mechanism 5 and thus of the tilt window 1 is somewhat blocked and secured against the accidental slamming shut under the influence of a gust of wind or the like. - To willingly shut the tilt window 1 from its tilt position, the user must first overcome the resistance of the motion of the
short arm 14 which is counteracted by thecam 25 and which must first be unlocked because theshort arm 14 needs to push thecam 25 along its shortslanted side 25b upward with its side edge 14a. - This solution does not unnecessarily increase the force.
- There is a possibility to reduce the force required to unlock the tilt window from its tilt position to a limited extent by cutting the elastic element, for example at one of the
sections 26b such that saidcut section 26b no longer has any influence on the forces required for the elastic deforming of theelastic element 24. - Note that it is also conceivable that a similar additional anti slam device is provided in other locations, for example on the level of the angle between the
short arm 14 and theleaf section 7 or on the level of the angle between thelong arm 8 and theleaf section 7. - Thus the
anti-slam device 18 can be mounted on each of said mutuallyrotatable parts cam 25 in the open tilt position of thescissor mechanism 5 hooks behind a side edge of another mutuallyrotatable part scissor mechanism 5. - The attachment of the anti-slam device to the scissor mechanism is not necessarily by glueing, but can also be done with clips, screws or any other suitable way or can even be provided with the manufacture of the scissor mechanism as an integrated component of the constituent elements of the scissor mechanism, for example that the plate-shaped
element 19 is formed by one of the arms itself to which the elastic element is attached. - Note that the
anti-slam device 18 can also be mounted with said underside of the plate-shapedelement 19 facing upward with the cam pointing upward, for example when theshort arm 14 is located above thelong arm 8 instead of below as shown in the figures or that the plate-shapedelement 19 can be mounted with its opposite top under thelong arm 8 or another element. And that consequently the concepts "underside" and "downward" may not be interpreted restrictively as relating to an absolute direction indication. - Certain characteristics listed again:
- that the
longitudinal body 26 on the level of theseats 27 can be made thinner than the sections on either sides of eachbracket 27; - that the base 25a of the
cam 25 for example extends over a length that is approximately half the length of thecentral section 26b of thelongitudinal body 26 between bothseats 27; - that the
long side 25c and the base 25a enclose an angle B between 15 and 20°, preferably an angle of around 18° and this angle B faces said first end of thecentral section 26b of thelongitudinal body 26; - that the
short side 25b and the base 25a enclose an angle of approximately 70°; - that the
elastic element 24 with itslongitudinal body 26 and itscam 25 are made of an elastic material such as polyamide; - that the plate-shaped
element 19 and theseats 27 are made of a metal sheet material such as stainless steel; - that the
cam 25 with the angle B between the base 25a and thelong side 25c of thecam 25 faces the first end 9 of thelong arm 8; - that the tilt window contains a fixed
frame 2 and aleaf 3 which is hingeably mounted at the bottom in the fixedframe 2 into a tilt position, whereby the tilt window 1 is provided at the top with ascissor mechanism 5 mounted between the fixedframe 2 and theleaf 3 and is attached thereto with itsframe section 6 and itsleaf section 7 respectively. - The present invention is by no means limited to the embodiments described as an example and shown in the figures, but an anti-slam device according to the invention can be realised in all kinds of forms and dimensions without departing from the scope of the invention as defined by the appended claims.
