Definitions

  • This invention relates to a closing system for a tilting window with a fixed frame, a wing provided thereupon, being tiltable around a horizontal geometrical tilting axis, and with the closing system comprising at least one built-in scissor-type mechanism interconnecting the wing and the frame, and an actuating mechanism for actuating this scissor-type mechanism, which operating mechanism comprises a handle and a coupling between this handle and the scissor-type mechanism.
  • a closing system and tilting window are disclosed in e.g. DE 2330115 .
  • tilting window is intended in a broad sense, such that thereby, a tilting window tilting towards the interior, as well as a turning window tilting towards the exterior have to be understood.
  • tilting windows are situated at such a height that the handle would be out of reach for the user if such handle were provided on the wing or the fixed frame. Amongst others, this is the case with so-called high-level opening lights or fanlights.
  • said coupling between handle and scissor-type mechanism is a rod coupling which is provided at the height of the frame at the inner side of the fixed frame.
  • a disadvantage of such known tilting window is that the mounting of the scissor-type mechanism and of the coupling is relatively difficult and time-consuming.
  • the present invention aims at offering a solution for this and other disadvantages.
  • the coupling comprises a first part which is provided with one extremity on the fixed frame and is connected to the handle, a second part which is mounted on the edges of the wing and is connected to the scissor-type mechanism, and, in the proximity of the tilting axis of the wing, a transmission mechanism between the two parts in order to transmit the movement of the one part to the other part.
  • one or more closing elements can be provided on this part, if desired, which closing elements, when the coupling for closing the scissor-type mechanism is moved, engage behind stops on the fixed frame and thereby form one or more additional closing points.
  • the second part of the coupling which is mounted on the wing, in fact can be extended beyond the scissor-type mechanism and can there be provided with at least one closing element which cooperates with a stop on the fixed frame for forming an additional closing point.
  • the scissors mechanism is built in at the top, and the part of the coupling which is mounted on the wing comprises rods or laths which can be shifted in grooves which are present at least on the upper edge and on a lateral edge of the wing, and a non-rigid corner connection which interconnects these rods or laths on both edges.
  • the mounting of the closing element is easy and fast. If standard profiles are used for the wing and for the fixed frame, the grooves are already present, such that they do not have to be manufactured especially for the rods or laths of the coupling.
  • the transmission mechanism comprises a driving element which is fixedly seated on the first part of the coupling connected to the handle, and a catch piece which is fixedly seated on the second part of the coupling, whereby, on the catch piece or on the driving element, a pivot is located which sits in a slot provided on a part of the driving piece, the catch piece, respectively, extending along the lateral edge of the closed wing.
  • the actuating mechanism is intended for a tilting window according to any of the preceding forms of embodiment.
  • a scissor-type mechanism comprising a scissors base with a base piece and an actuating strip which can be shifted in respect to this base piece, and at least two arms, is described.
  • the scissor-type mechanism comprises three arms, to wit a connecting arm attached at the base piece hingeing as well as shiftable, an auxiliary arm which, on one hand, is hingeably attached between the extremities of the connecting arm and, on the other hand, is hingeably connected to the base piece and an actuating arm which, one one hand, is hingeably attached on the actuating lath by means of a pivot which can be shifted in a slot in the base piece and, on the other hand, is coupled to the auxiliary arm by means of at least one catch pin protruding through an opening in this auxiliary arm, whereby the extremity of the actuating arm cooperates with a guide provided on the base piece, in such a manner that, when the actuating lath is shifted into one direction in respect to the base piece, the actuating arm bumps with its extremity against the guide and is forced to rotate, and therefore, by means of the catch pin, rotates the auxiliary arm which, in its turn, rotates the connecting arm.
  • the guide is directed inclined in respect to the longitudinal direction of the base piece, and the extremity of the actuating arm is bevelled, too.
  • the extremity of the actuating arm is bevelled in a step-shaped manner and shows at least two, and preferably three, cams which successively come into contact with the guide.
  • two catch pins can be present which protrude in the opening in the auxiliary arm.
  • the tilting window is a tilting-down window substantially consisting of a fixed frame 1, at which a wing 2, by means of hinges 3 at the bottom, is provided tiltable around a horizontal geometrical tilting axis.
  • the wing 2 tilts towards the inside and the side towards which the wing 2 tilts, thus, hereafter is called the inner side or front side.
  • the wing 2 is provided with a groove 4 over its entire circumference, which groove substantially has the form of a reversed T and is formed between two ribs 5 with extremities which are bent and directed towards each other, such that laths, which, whether shiftably or not, are provided in the groove 4, are retained in the groove 4 by said ribs 5.
  • the tilting window is provided with a closing system consisting of a built-in scissor-type mechanism 6 provided between the upper edge of the wing 2 and the upper edge of the fixed frame 1, and an actuating mechanism 7.
  • the actuating mechanism 7 consists of a handle 9 which is attached beneath the tilting window, within reach of a user, for example, on the wall, and a coupling 10 between the handle 9 and the scissor-type mechanism 6.
  • the coupling 10 is composed of a first part 11 which is provided with its upper extremity on the front side of the fixed frame and with its lower extremity is connected to the handle 9; a second part 12 which is mounted on the edges of the wing 2 and is connected to the scissor-type mechanism 6; and, at a distance of maximum 10 cm, and preferably maximum 5 cm, to the tilting axis of the wing 2, a transmission mechanism 13 which is provided between both said parts 11 and 12 in order to transmit the movement of the first part 11 towards the second part 12.
  • the first part 11 consists of a rod 14 which is shiftably provided in bows 15 which are attached on the wall and on the frame 1.
  • the transmission mechanism 13 consists of a driving piece 16 and a catch piece 17.
  • the driving piece 16 is formed by a substantially L-shaped profile, one leg 18 of which surrounds the upper extremity of the rod 14, is fixed thereon by clamping screws 18A and is situated against the front side of the frame 1, and the other leg 19 extends along the interior edge of the frame 1.
  • leg 19 On its side directed towards the wing 2, leg 19 is provided with two bent and parallel ribs 20 which together border a groove 21, whereby these ribs 20 are directed upwardly inclined towards the front side of the frame 1. These ribs 20 extend over the entire width of the leg 19.
  • the lower rib 20 connects to a downwardly directed rib 22.
  • the catch piece 17 is formed of a substantially rectangular element which is shiftably provided in the groove 4 of the wing 2, opposite to the driving piece 16, and which is connected to the part 12 of the coupling 10, provided on the wing 2, for example, by means of a coupling 23.
  • this catch piece 17, at the bottom and near its edge situated at the exterior side of the wing, is provided with a pivot 24 which is seated in said groove 21.
  • the catch piece 17, at said side is provided with a reinforcement rib 25.
  • a leaf spring 26 is clamped in a recess, said spring pushing against the walls of the groove 4 of the wing 2.
  • the second part 12 of the coupling 10 mounted on the wing 2 consists of two flat rods or laths 27 and 28 of synthetic material, which are shiftably provided in the grooves 4 of a lateral edge and of an upper edge of the wing 2, respectively, and which, at the height of the corner, are interconnected by means of a non-rigid corner connection 29, known in itself and schematically represented in Figure 1 by means of a dashed line, said corner connection, for example, comprising a chain which is shiftably guided between two connecting extremities in a tubular profile attached on the wing 2.
  • this lath 27 is attached to the catch piece 17 by means of said coupling 23.
  • this lath 27 has a toothed part at one extremity, for example, at its lateral edges, said part fitting into a complementary toothed part, for example, at the walls of a cavity at a thickened part of the catch piece 17, such that a solid coupling in the longitudinal direction of the lath 27 is obtained.
  • the lath 28 is connected to the scissor-type mechanism 6 by means of a similar coupling 30.
  • the scissor-type mechanism 6 substantially consists of three mutually connected arms, to wit the actuating arm 31, the auxiliary arm 32 and the connecting arm 33, which, at one extremity, are hingeably provided around pivots, 34, 35, 36, respectively, which are provided on a hinge basis consisting of a base piece 37 and an actuating lath 38 shiftable therein.
  • the base piece 37 has the form of a reversed gutter, bent edges of which are provided in the groove 4, at the upper edge of the wing 2, below the extremities of the ribs 5.
  • This base piece 37 is fixed on the wing 2 by means of a safety screw 39 which is screwed into the wing 2 through the base piece 37 and loosely through a longitudinal slot 40 in the actuating lath 38.
  • This actuating lath 38 is provided underneath the gutter of the base piece 37 in a manner shiftable in its longitudinal direction and thus parallel to the longitudinal direction of the base piece 37 and protrudes with its both extremities out of the base piece 37.
  • One extremity is connected to the lath 28 of the actuating mechanism 7 by means of said coupling 30 and has an end piece 38A which is provided with a toothed part cooperating with a toothed part on the extremity of the lath 28.
  • the pivot 34 on an extremity of the actuating arm 31 is attached to the actuating lath 38, at the location of a widened part 38B thereof.
  • the pivot 34 can be shifted in a longitudinal slot 41 in the base piece 37. This slot 41 is situated closer to the inner side of the wing 2 than the slot 40 situated in the middle of the actuating lath 38.
  • Said widened part 38B comes out of the base piece 37 towards the outside, such that the actuating lath 38, at the height of the widened part 34A, is guided through the inside of the wing 2.
  • the forces which are exerted onto the pivot 34 and which are responsible for wearing the slot 40 in the base piece 37 are deviated towards the groove 4 in the wing 2, which is more resistant against these forces.
  • the slot 40 only serves for letting the pivot 34 pass, such that it can drive the arm 31, and not as much for guiding this pivot 34.
  • the actuating arm 31 is widened, and at the side which, in open position of the scissor-type mechanism 6, is distal from the connecting arm 33, thus, with a wing 2 opening towards the inside, as in the example, this is at the inside, it is bevelled in a step-like manner, such that three catch pins or cams 43, 44 and 45 are formed which successively are situated closer to the pivot 34 and which, when the scissor-type mechanism 6 opens, successively cooperate with a guide directed towards the frame 1 and being inclined in the same sense as the extremity 42, said guide being formed by the inclined edge 46 of a stop 47 which is provided at one extremity of the base piece 37.
  • a second stop 48 is provided on the base piece 37, which stop, during closing, forces the actuating arm 31 to choose the desired course, by coming into contact with an edge 31A of this actuating arm 31.
  • the auxiliary arm 32 is hingeably connected to the base piece 27 and, at its other extremity, by a hinge pivot 49, is coupled to a part of the connecting arm 33 situated between said extremities.
  • the pivot 35 is standing, for example, next to the safety screw 39 on top of the part of the base piece 37 forming the stop 47.
  • the auxiliary arm 32 comprises an opening 50 which is more or less L-shaped, with a groove 51 in the longitudinal direction of the auxiliary arm 32 and, at the side of the pivot 35, a wider part 52 adjoining thereto.
  • the pivot 36 of the connecting arm 33 protrudes through a longitudinal slot 55 in the base piece 37.
  • the connecting arm 33 which connects the frame 1 and the wing 2, is fixed with one extremity, by means of the pivot 36, on a foot 56 which, above the actuating lath 38, is shiftably seated in the base piece 37 and which can not pass through the slot 55.
  • the base piece 37 At its extremity most distal from the slot 40, the base piece 37, at the underside and at opposite sides of the slot 55, is provided with an inclined part 37A, as represented in detail in Figure 8 .
  • the underside of the base piece is inclined towards the actuation lath 38.
  • the slot 55 is provided in a wider slot, and the pivot 36, between the bottom of this slot and the actuating arm 33, is surrounded by a spring 36A which pushes the connecting arm 33 away from the base piece 37.
  • the other extremity of the connecting arm 33 is hingeably connected to the frame 1 by means of a pivot 57 standing on a base 58.
  • This base 58 is placed, with a turning movement, into the groove 4 at the underside of the upper side of the fixed frame 1, such that it engages with one edge under a rib 5 of the groove 4, and, by tightening an inclined pressing clamp 59, is clamped, as represented in detail in Figure 11 .
  • a drilling screw 59A By means of a drilling screw 59A, the base 58 is retained at its place.
  • the pivot 57 has a thickened head around which the extremity of the arm 33 is removably provided.
  • This arm 33 is retained on the head of the pivot 57 by a locking wheel 60 which is provided next to the pivot 57 on the arm 33, turnable around a pin 61, and which protrudes with one edge 62 into a groove provided at a part of the pivot 57 protruding at the underside beyond the arm 33.
  • the edge 62 is provided with an interruption 63 which is such that, when it is situated opposite to the pivot 57, the edge 62 no longer prevents the removal of the arm 33 from the pivot 57.
  • a not-represented spring provided around the pin 61, pushes the locking wheel 60 into that position in which the interruption 63 is situated at a distance from the pivot 57.
  • the arm 33 can be removed from the pivot 57, such that the scissor-type mechanism 6 is freed from the fixed frame 1, and the wing 2 can be tilted entirely, for example, for being cleaned.
  • the locking wheel 60 is no longer held, it will turn under the influence of the spring back into its original locking position.
  • Said reinforcement rib 25 prevents that, when the wing 2, after a complete tilting, is swung back and closed again, the pivot 24 would be situated above the groove 21.
  • one or more closing pins 64 can be provided which cooperate with stops 65 which are attached to the frame 1.
  • Such closing pin 64 for example, is provided at the connection end of the corner connection 29 coupled to the lath 28.
  • such closing pin 64 is provided, which cooperates with a stop 65 on the frame 1, and to this aim, the lath 28 is prolonged beyond the scissor-type mechanism 6 by means of a rod 66 which, by means of a coupling analogous to said coupling 30, is connected to the actuating lath 38 of the scissor-type mechanism 6.
  • the rod 66 itself also can connect, by means of a corner connection, to a rod along an upright edge of the wing.
  • the handle 9 In order to open the tilting frame, the handle 9 is drawn downward.
  • the driving piece 16 By the intermediary of the rod 14, the driving piece 16 is moved downward.
  • the catch piece 17 protrudes with its pivot 24 into the groove 21 of the driving piece 16, it is also moved downward, causing the lath 27 to be drawn downward, too.
  • the lath 28 and the actuating lath 38 of the scissor-type mechanism 6 then are moved along the wing 2, to the right hand side as seen in Figures 6, 7 , 8 , and 12 to 17.
  • the closing pins 64 are freed from the stops 65, and the closing pin 67 is brought beyond the ribs 68, such that the connecting arm 33 no longer is blocked, whereas simultaneously, by the movement of the actuating lath 38, also the actuating arm 31 of the scissor-type mechanism 6 is moved to the right.
  • the actuating arm first will be able to move freely over a certain distance until, as represented in Figure 12 , it comes into contact with the edge 46 of the stop 47.
  • the groove-shaped part 51 of the auxiliary arm 32 is parallel to the shifting direction of the arm 31, as a result of which the catch pins 53 and 54 of the actuating arm 31 can move freely in this groove-shaped part 51.
  • the position of the other arms 32 and 33 of the scissor-type mechanism 6 thus will remain undisturbed, and consequently the tilting window still will remain closed.
  • edge 47 provides for that the actuating arm 31 is forced to rotate, which can be necessary with relatively heavy windows, whereby the natural lever of the scissor-type mechanism 6 is not sufficient for pushing the window open.
  • the shiftable pivot 36 hereby moves to the right in the slot 55.
  • the distance D between the pivot 34 of the actuating arm 31 and the contact point of the cam 43 with the stop 47, measured perpendicular to the shifting direction of the actuating lath 38, is chosen as large as possible, such that a maximum lever effect is obtained for turning the actuating arm 31, as a consequence of which also heavier tilting windows can be pushed open by the user without major effort.
  • the form of the ribs 20 is chosen such that the pivot 24, during the tilting open of the wing 2, on one hand, can move unhampered in the groove 21 and, on the other hand, maximally transmits the forces between the driving piece 16 and the catch piece 17 in vertical direction.
  • the upper side of the base piece 37 of the scissor-type mechanism 6 is somewhat bevelled in order to allow for that the outwardly turning extremities of the arms 31, 32 and 33 also can move vertically, even in a limited manner, in order to allow for the vertical movement H of the pivot 57 during the tilting of the wing 2.
  • the arm 33 is manufactured of spring steel in order to be able to bend along sufficiently with low tilting windows which are characterized by a large movement H.
  • the closing system according to the invention can be constructed modularly and moreover can be mounted very easy and fast.
  • the scissor-type mechanism 6, the lath 28 and the corner connection 29 are connected to each other and slid into the groove 4 in the upper edge of the wing 2.
  • the base piece 37 of the scissor-type mechanism 6 is attached by means of one single safety screw 40.
  • the lath 27 with the catch piece 17 is slid, starting from the underside, into the groove 4 on an upstanding edge of the wing 2, and the lath 27 is connected to the corner connection 29. During mounting, the catch piece 17 is kept in its place by the clamping force of the leaf spring 27.
  • this latter can be provided at its underside with a small hook which can be broken away.
  • this small hook rests against the underside of the wing, the catch piece is situated at the correct distance to the tilting axis. With the first movement of the catch piece 17, this small hook breaks off.
  • the window does not necessarily have to be provided with an inwardly tilting wing 2.
  • the tilting window also may have an outwardly tilting wing 2. It is clear that in such case, the terms 'interior or front side' in the aforegoing description must be replaced by 'exterior or back side'.
  • the frame 1 and the wing 2 are manufactured of aluminium profiles, however, it is clear that they may also be manufactured of profiles of another material, such as steel or synthetic material or of wooden beams.
  • a cross-section of a part of a window is represented consisting of profiles of synthetic material reinforced with metal profiles.
  • the grooves 4 then are situated in the edges of wing 2, hoever, countersunk.
  • the scissor-type mechanism 6 described in the aforegoing is particularly suited for being used in a closing system with an actuation mechanism 7, as described in the aforegoing, however, it is clear that this scissor-type mechanism also can be used with other actuating mechanisms and, for example, with actuating mechanisms comprising a handle provided on the wing or the fixed frame.
