Description

à 1; Surcharge protection for a tilting window and scissor and tilting window | The present invention relates to a toggle lock for a tilt window.

Zen tilting window is a window with a fixed frame and a wing that is hinged in the fixed frame. | 10 With a tilting window, the wing can hinge around a: cool horizontal tilting axis at the bottom of the | window until a certain opening is created at the top that we | Name the tilt position used for momentary | 15 or long-term airing. | To hold the wing in its tilt position, it is common practice to fit a pair of scissors Loe mounted at the top between the fixed frame and the wing and limiting the opening of the wing around the imaginary tilt axis to a certain open tilt position. generally composed of a long arm and a short arm which are hingedly connected to each other, The long arm is hingedly connected to the fixed frame via a frame part with a first end and slidable at the other second end via a wing part and connected to the vieugel,

{BE2019 / 5172 The short arm is pivotable at one end with the long | arm joined at a central point between the ends of the long arm and is pivotable at its other end | connected to the wing part, 9 When the window is closed, the scissors are closed and lie concealed | arranged in the rebate between the fixed frame and the | wing, in which the arms are parallel to each other.

9 10 When the window is tilted open, the arms 9 rotate, whereby the hinge at the second end of the long 9 arm moves into a slot in the wing part until | Empty the end of the slotted hole.

i5 The shear thus acts as a limit to falling open when tipping open, which is important in terms of safety. The weight of the sash helps to keep the sash coen, Tipping windows can, however, also have a tendency to unintentionally close back from the xip position, for example due to underpressure caused by an accidental gust of wind.Therefore, such scissors are usually fitted with a safety fuse as standard. This is a kind of clip that is mounted on the serste end of the long arm and which holds the wing in the open tilt position with a certain resistance, but which should also not have too much resistance to look like one wants the wing again. to keep the operation somewhat smooth and comfortable without requiring too much force.

However, there are certain trends in the market for the 9 windows, namely that: 9 5 - the wing profiles are getting thicker in depth | to be more thermally efficient; 9 “the windows keep getting higher; and, | = more and more triple glass is used in the | vieugel, 9 10 9 Each of these trends means that the center of gravity of the | wing comes closer to the vertical plane through the imaginary tilt axis, which is why the weight of | the wing helps less and less to keep the sash open and, consequently, the sash will close more easily in case of a wind disturbance or the like. Providing a stronger lock fuse as standard, however, is not a solution because then the operation of, for example, less high windows becomes too heavy.

The invention constitutes a surcharge lock which can be used additionally or alone and can preferably be retrofitted.

This can be provided for high windows or used in case of problems.

To this end, the invention relates to an additional fuse for resisting the slamming of a tilting window which is held in its open tilting position by means of a pair of scissors, characterized in that the additional fuse comprises an elastic element and a plate-shaped or other element.

| BE2019 / 5172 | with a side for attaching the supplemental securing device to the scissors, the elastic element comprising a cam-shaped part {or cam which, in its rest state, extends from the flail-shaped | or other element and wherein the elastic element # 2 has a certain resistance to pushing the cam of the elastic element away from the aforementioned rest state. # A surcharge fuse according to the invention is intended to be fixed with its plate-shaped element Le on one of the | 10 constituent parts of the scissors or form part thereof in such a way that the cam of the elastic element 9 is in the trajectory of one of the other constituent parts of the scissors when the scissors are opened and hooks behind it in or before the open tipping position of the share has been reached.Because the cam of the elastic element hooks into the open position to pilock the share in this position, this provides an extra resistance against striking the tipping window, because the The elastic resistance of the hooked elastic element must be overcome, Preferably, the additional fuse is glued to the scissors and for this purpose is provided, for example, on its plate-shaped part with a double-sided adhesive tape that is covered: with a peelable cover film that must be removed at the moment the surcharge fuse must be glued to the scissors.

Thus, the surcharge lock can be easily mounted on scissors of an existing tilting window or as an extra

{5 stroke safety in case of a high window and when this 9 proves to be necessary. | In this way, a classic scissors can be used for both low and high windows and, in the case of a: high window, an additional surcharge protection on the scissor | be confirmed. | Preferably, the supplement lock is mounted on the long arm with the cam in the range of the rotational movement of the short arm relative to the long arm when the tipping crane is tipped open.

The cam is preferably designed as a triangle with its point pointing downwards and which, in the closed position of the scissors, is located next to and at a distance from a side edge of the short arm. Thus, the resistance to be overcome at the start of the the tilting of the tipping window is limited because the short arm then comes into contact with a sloping side of the cam at an angle when tipping open, so that the force required to push the cam up from its rest position to the closed position of the tipping window is less,

The invention also relates to scissors provided with a non-return safety device according to the invention and a tipping crane equipped therewith.

The invention also relates to the use of a con-charge fuse according to the invention for the use of a safety device

With the insight to better demonstrate the features of the invention Le 3, a preferred embodiment is described below by way of example without any limitation in character. van sen Looslagzexering according to the invention fitted to 9 the scissors of a tipping window, with reference to the accompanying drawings, in which: 9 figure 1 shows schematically and in cross section a tipping crane 9 equipped with san Scissors with a | blowback fuse according to the invention; figure 2 represents a front view according to arrow F2 in figure 1; figure 3 represents in perspective the scissors indicated by F3 in figure 2; figure 4 shows to a larger scale the non-return fuse according to the invention, which is indicated by Pd in figure 3; figure 5 represents a bottom view according to arrow F5 of the retrieval cut in fiquur 4; figure 6 shows the blowback fuse of the figures 4 and 5 in an exploded position; figure 7 shows a cross-section according to line VII-VII in figure 4; figure 8 represents the scissors of figure 3 but shown in three different positions; figure 9 represents a local section according to line IXIA in figure 8;

{figure 10 shows the local cross-section of figure 3 | but sustained at the beginning of the | chicken window, | 5 The tilting window 1 shown in figure 1l consists of a fixed frame 2 and a wing 3 which can be hinged at the bottom in the | Frame 2 is mounted around an imaginary horizontal 9 tilt axis 4, 9 30 Between the fixed frame 2 and the wing 3 a scissor 5 is arranged which limits the maximum tilt angle over which the 9 wing 3 can be tipped open, as in the case of 9 £ iquur 1. In figure 3, by way of example, a classic scissors is shown, as can be seen in more detail from this figure 3, the scissors are composed in a known manner of a frame part 6 for fastening to the fixed frame 2; s vent part 7 for fixing on the vent 3; long arm & which is rotatably connected to the frame part 6 with a first end 9, in this case by means of a double link 10, and is connected to the other second end 11 by means of sliding and hinging to the wing part 7, in this case by means of of pivot pin 12 which engages a slot cat 13 of the wing portion 7, and a short arm 14 pivotally connected at one end 15 to the lance arm 8 with a pivot pin 16 between the first and second ends of the long arm is hingedly connected to the wing part 7 at its other end.

| 8 The rotatable connection between the long arm & and the frame part 6 can also occur in other forms than by means of a cubbeie link 10, for example direct: 5 or by means of more than 2 arms. The combined sliding and hinge connection between the long arm 8 and the wing part 7 can also be realized in other ways 9 than by means of a hinge pin 12 and slotted hole 13. | Usually a pair of scissors 5 is always provided with a | xaderdeci &, a wing part 7 and in between a Long arm 3 and a short arm 14 which, when opening and closing the tilting window 1, is pivotable relative to the Long arm 8. The Long arm €, the short arm 14 and the wing part 7 are rotatably connected to each other and together the mutually rotatable parts 7, & and 14 are combined here.

The scissors 5 may be provided on the wing side with a blowback fuse, which is not shown here, specific to the invention is that the scissors 5 is provided with a blow-back fuse 18 as shown in Figs. 4 to 7, which in this case is on the lance arm 8. is selected as shown in figure 3 for the resistance to slamming of the tilting window 1. The surcharge fuse comprises a plate-shaped element 15 with a side edge 20 and a bottom side 21 which is provided with a

{self-adhesive adhesive layer 22 cf of a double-sided adhesive tape {to attach the surcharge fuse 18 to the scissors 5 | confirm.

In the unassembled state, the adhesive layer | are provided with a peel-off foil 23. | The surcharge fuse 18 further comprises an elastic element 24 9 which is disposed next to and along the side edge 20 and with the | plate-shaped element 19 is connected and which comprises a cam or cam-shaped part 25 which, in its rest position, projects below the bottom side 21 of the plate-shaped element 19, the whole being such that the cam 25 through | an upward force can be elastically pushed upward in a direction isodirectionally on the underside 21 of the plate-shaped element 19, 25. The elastic element is preferably integrally made of an elastic material such as polyamide. in the example of the figures, the elastic element 24 is designed with a longitudinal elastic body 26 on which the aforementioned cam 25 is arranged and which is contained in two seats 27 of the plate-shaped element 19 along the aforementioned side edge 20, the aforementioned cam 25 between both seats 27 are provided and the seats 27 are such that they allow an elastic stretch of the body 26 in the longitudinal direction X-X 'but prevent its rotation in the seats 27. For this purpose, the longitudinally elastic body 24 is for example in this case designed as a flat strip and el: of the seats 27 is formed by a U-shaped bracket BE2019 / 5172: with legs 27a and 276 between which the longitudinally elastic body 24 is held; Extend the legs 27a and 27b of the U-shaped fiber 27; 3 extends parallel or substantially parallel to the underside 21 of the plate-shaped element 19 and the opening 27e of the U-shaped bracket 27 is towards the claate-shaped; element 19 turned.

The cial-shaped element 19 is made, for example, of a metal plate of stainless steel or the like, and the seats 27 are, for example, formed by folding the plate double naked.

For example, the elastic element 24 may be slid laterally along the openings 270 into the seats 27 and then secured against lateral removal and twisting by providing the longitudinal body 26 at the location of the brackets 27 with an undercut or with an arch 28 and at least one leg 27b of the brackets 27 in the undercut or in the groove 28 for plotting as shown in Figure 7.

The brackets are connected by a downwardly directed collar 25 to the plate-shaped element 19, which collar 29, when mounted, can serve to align the surcharge fuse 18 against a side edge 30 of the long arm.

In order to secure the ionic body 26 in longitudinal direction KX-X "in the seats 27, this longitudinal body 26 is, for example, in the portions 26a at the position of 17; the seats 27 are made thinner than in the portions outside the seats 27, in the central portion 2656 and at the ends 260, 3 respectively. The cam 25 is preferably formed as a triangle attached to its base 25a or connected to the : central portion 26b of the longitudinal body 26 and | which has a short side 250 and a long side 25c that | enclose together an angle that faces away from the | 10 underside 21 of the plate-like element 15. The cam 25 is disposed with its base 25a from the center of the central portion 26b and extends from one seat 27 on the long side side 25c to a distance from the other seat 27 on the short side 250, which distance in the example is approximately equal to half the length of the central part

260.2G The long side 250 encloses with the base 25a an angle B of between 15 and 20 °, preferably an angle B of about 18 °. The short side 25b encloses an angle A of approximately 18 ° with the base 2532. 70 °. In the example, the locking fuse 18 is mounted on the long arm B as shown in Figure 2 with the collar 29 against the side edge 30 of the long arm 8 and in such a way that the cam 25 with its short side 25b behind it towards the first end. 2 facing side edge 14a of the

| BE2019 / 5172 12 short arm 14 hooks when the share 5 is opened to its maximum tipping position, whereby the cam 25 with its angle B 9 between the base 25a and the long side 25c towards the serste | end 3 of the long arm 8 is pointed. ) 5 When so mounted, the elastic member 24 extends in its longitudinal direction along the side of 30 and | during opening and closing of the scissors 5, the cam 25 is located in the path of the short arm 14 which is located during the opening and closing of the scissors 5 relative to the long arm 8 rotates about the hinge pin 16 and in the closed state of the scissors 5, the cam 25 falls adjacent to the opposite side edge 14b of the short arm 14 and at a lateral distance D from it as shown in Figure 9,

The operation of the surcharge fuse is very simple and is illustrated with reference to figure 8, which shows three cupped positions of the scissors 5, namely a closed position I; an open position ITT and an intermediate position II corresponding respectively to a closed tilting window, a maximally tilted open tilting crane and a Cussen position of the tilting window.

In the slashed position I, the short arm is a distance D from the cam 25 as seen in the bottom view of the corresponding figure 9. When the scissors 5 is opened, side edge 14b of the short arm 14 comes into contact with the blade. long side Z25c of the cam 253 as shown in figure 10,

[13: When opening further, the short arm 14 pushes the cam 25 | up, as shown in the cussion position II in Figure 8, {Lot when the cam 25 hooks with its short side 25b behind [the short arm 14 as shown in the IT position! of Figure 8, corresponding to the open position of | figure 3. 9 This makes the open tipping position of ds link 5 and therefore of | the tilting window L is somewhat blocked and secured against accidental tcesian 9 10 under the influence of a wind gust or the like, 9 In order to be able to close the chin window 1 intentionally from its tilted position, the user will first have to overcome the resistance of the movement of the short arm 14 which is emptied by the cam 25 and which must first be unlocked by the short arm 14 having to push the cam 25 with its side edge 14a upwards along its short oblique side 25b. This solution does not increase the force where it is not needed.

There is a possibility to reduce to a limited extent the force required to release the tilting window from its tilted position by, for example, cutting the elastic element through one of the parts 26b, so that this cut-through part 26b no longer has any influence on the forces required. for the elastic deformation of the elastic element 24,

Note that it is also conceivable that a similar

| additional insurance on other ications = is | provided, for example at the corner between the xorte arm 14 and the wing part 7 or at the location of the | angle between the long arm 8 and the wing part 7, | 5 It is therefore the case that the surcharge fuse 18 can be mounted | on each of the aforementioned mutually rotatable parts 7, 8 and 14, wherein the cam 25 is in the open tilting position of the | scissor 3 is hooked behind a side edge of another part 7, © or 14 that can be rotated 9 10 and is pushed upwards by this last 9 part when closing the scissor 5. The attachment of the surcharge on the scissors does not necessarily have to be done by gluing , but can also be provided by clamps, screws or in any other suitable manner or even in manufacture of the scissors as an integrated part of the constituent elements of the scissors, e.g. the plate-shaped element 19 is formed by one of the arms itself to which the elastic element is attached.

Note that the slack fuse 18 can also be mounted with the aforementioned underside of the plate-shaped element 19 upwards with the cam pointing upwards, for example when the short arm 14 is above the long arm 8 instead of below it as in the figures or that the plate-shaped element 19 can be mounted with its opposite top side under the long arm 8 or some other element.

And that consequently the concepts “bottom” and “down Lo” are not restrictive Mag

: BE2019 / 5172 9 15 are interpreted as referring to an absolute direction indication.

The present invention is by no means limited to the if; In the example described and shown in the figure, a recoil fuse according to the invention can be realized in all shapes and sizes without departing from the scope of the invention. steps.
