Description

1 2489876

  The invention relates to a fitting for the sliding leaf of windows, doors, or the like, formed from

  standard profiles of wood or synthetic material

  spanning the usual rotating and tilting windows, located, in the closed position, in the same plane as at least one neighboring leaf, preferably rotating and that can be moved, to slide, first perpendicularly and then parallel to this plane, to bring it behind the neighboring leaf, and in which may be placed on the inner surface of the frame, an upper rail and a lower rail for, respectively, the leaf separating arm rollers preferably forcibly actuated by a lock linkage installed concealed in the leaf rebate, and pebbles

lower support of the leaf.

  Windows or sliding sash doors are

  known for a long time and under different modes of

  tion. Thus, patent DE 1 709 307 shows a fitting for a rotating and sliding leaf in which is disposed, on the leaf, a spacer device formed of two spacer arms, one of the spreader arms being hinged to the leaf in a fixed position but so as to be able to pivot while the other spacer arm carries at its end located towards the leaf a finger arranged so as to be able to slide in the plane of the leaf, in a guide provided on the leaf. In addition, the two spacing arms are connected together, at the end facing the frame, by a hinge which is itself slidably arranged in a continuous groove provided in the leaf, in the plane of the frame. this one. This fitting is relatively complicated and requires special profiles - for the frame and the leaf. It is the same for the wing fitting which can slide horizontally according to German Offenlegungsschrift No. 1,784,710. In this known fitting, it is not possible to forcibly actuate the spreading arm of the leaf. In addition, here too, the profile of the leaf and the

  dormant must have a special shape, which makes the manufacturer

  significantly more expensive. Moreover, when

2 2489876

  leaf moves perpendicular to the plane of the frame, the roller which supports the leaf must pass, through a slot, the frame profile in a profile attached below and which contains the transverse movement guide of the leaf. The fitting defined at the beginning and from which part the invention is also known (see "Anschlaganleitung"

  for "Abstell-Schiebebeschlag" No 1000 of the firm Fuhr-

  Infront, August 1979). In this known fitting, spacer arms forced by the locking linkage are provided at the upper edge and at the lower edge of the leaf so that the leaf can be

  displaced, in parallel with himself, from the position of

  at a sliding position perpendicular to the plane of the frame. For guidance when sliding the leaf, slides are screwed above and below the inner surface of the frame. This known fitting is not suitable for leaves which, for ventilation, must be brought from the closed position to a tilting position. In addition, this fitting is only usable

  for sliding leaves that can be used in combination with

  sound with neighboring leaves installed in a fixed way. As is known, the fixedly installed leaves are placed lower in the frame while the swinging or swinging leaves project beyond the inner surface.

  standard profiles for leaves and window frames.

  The object of the invention is to improve a fitting of the species defined more precisely at the beginning, so as to ensure that the leaf can be tilted from the closed position to an aeration position as well as the sliding of the gate. leaf itself, even when the neighboring leaves are themselves rotating leaves, and in such a way that by using the wooden profiles or

3 2489876

  synthetic materials for rotating and tilting windows, it is possible to mount the fitting without modifying the profile and without performing special special operations on the profiles. In addition, the fitting must be suitable for both light and large leaves and

  heavy and that it allows safe and easy handling.

  According to the invention, this problem is solved by the fact that at least two rollers having axes parallel to the plane of the leaf are fixed rigidly with mutual spacing.

  the inner surface of the leaf and that in any posi-

  leaf, they rely on a truck that can

  roll on the lower rail, parallel to the plane of the

mant.

  It is true that a truck that can run parallel-

  in the frame of the frame, for sliding leaves, is in itself known by the utility model DE 1 916 708. But in it, when sliding perpendicularly to the plane of the frame, the simply sliding leaf abuts first on the carriage so that the frame profiles must be of a special nature and in addition, there are difficulties when it comes to crossing the spacing between the frame profile and the carriage when the leaf moves perpendicularly. in the frame of the frame. Since in the new constitution, the leaf is constantly supported on the carriage, so in the closed position as well as in the tilted position and in the sliding position, but the carriage rests on a fixed or set rail on the inner surface of the frame,

  all parts of fittings which are essential to the

  For the lower region of the leaf, sliding and sliding are outside the plane of the frame and the leaf, so that in these regions the profile of the door leaf and that of the frame do not require any machining or any modification. In addition, an easy sliding of the leaf perpendicular to the plane of the frame is obtained, because it is not necessary to overcome a gap between the profiles. So even heavy leaves can be

  brought easily and smoothly from the closing position

  re at the sliding position. Another advantage lies in

- = 4 2489876

  in that the rollers serving to move the leaf perpendicularly to the plane of the frame form at the same time

  LEMENT. The door leaf can be locked in the lower region of the leaf in the usual way by means of

  locking linkage and central locking.

  In the case of heavy windows, three or more rollers, spaced from each other, can also be provided without difficulty for the support of the leaf during the movement

  perpendicular to the plane of the leaf.

  It is particularly advantageous that all

  the rollers participating in the movement of the leaf perpendicular

  in the frame of the frame are rigidly connected to each other, as to the torque, by a common shaft so that

  we can make the movement of the leaf perpendicular-

  the. This is particularly important in the case of fairly large or heavy doors, where under the force transmitted unilaterally, the classic leaf would twist

  and would not follow uniformly the perpendicular movement

  the frame. Independent protection is

  claimed for this characteristic.

  Since the rail in the lower region, as well as the slide in the upper region, are placed against the inner surface of the frame, the lower rail can be relatively wide, so that the leaf, by its pebbles, is based constantly on a cart

  relatively wide which, thus, surely prevents a rocker-

  is lying. Advantageously, the running gear of the trolley

  has at least two support rollers guided with

  mutually perpendicular to the plane of the frame and the rollers fixed to the leaf rest on the carriage, in any position of the leaf, in the region

  between the guide planes of the two support rollers

  yours. It is thus ensured that the weight of the leaf is always transmitted to the truck in a region between

2489876

  the two support rollers of the trolley so that everything

  risk of tipping of the truck is excluded.

  The leaf can pivot about the common axis of the rollers fixed to the leaf, by means of at least two spacing arms, in an intermediate position of the locking linkage, to take a

  tilting position. Actuation of the spreading arms

  through the lock linkage

  can be done in a forced way so that a rocker-

  leaf can be triggered forcibly by

  through the central closure.

  It is important and particularly advantageous that in any position, the leaf is connected to the upper region of the leaf by constant engagement of the rollers of the end of each spacer arm located towards the frame in the guide path parallel to the plane the frame that has the upper rail that can land on the inner surface of the frame. It is thus excluded that the end of the spacer arm located on the side of the frame does not participate in the movement of the leaf perpendicular to the plane of the frame. On the contrary, despite the concealed installation of the spacer arms in the gap of the leaf, the ends of the spacer arms located towards the frame still remain in the plane of the guide path of the rail laid above the leaf, on the inner surface of the frame. It is thus ensured that in this region also the leaf profile corresponds practically

  to the usual profile of rotating and tilting windows.

  It is only necessary to machine-slightly the profile,

  which is explained more precisely below.

  To ensure, despite the concealed installation of the spacer arms, that they have a structure such that when sliding the leaf they can slide surely without disturbance along neighboring leaves including when they are themselves rotating leaves, it is particularly advantageous that each arm

  distance between its ends connected to the

  and in the leaf, a region of section unhooked in Z. Thus, in combination with the wide carriage, it is ensured, at the lower end of the leaf, that in the sliding position, the sliding leaf is at a great distance of the frame and so that it can be slid surely along any kind of neighboring leaves. Independent protection is

claimed for this structure.

  The new constitution of the fitting makes it possible to significantly reduce the cost price of these leaves

  sliding windows and doors. It must be remembered that

  Around 90% of all windows in the Federal Republic of Germany are pivoting and tilting windows and as a result these and their synthetic and wooden profiles can be mass-produced at low prices. Profiles of this kind can be used without significant machining for the frames and leaves of windows and doors if the new fitting is used. The invention is explained more precisely below

  The frame 1 of the window shown in FIGS. 1 and 2, as well as the leaves 2 and 3, are formed, in the example shown, of wooden profiles made of

  series and usually used in rotating windows.

  a rotating leaf that can be opened by the handle 4.

  The details of the hardware of this leaf are not

  felt because door fittings of this kind are known. It was simply indicated that the leaf 2 is in the closed position, which also corresponds to the

  represented representation of the handle 4 of the central closure

  the. The closed position is hereinafter referred to as "I".

  On the other hand, leaf 3 is in a posi-

  ventilation or tilting in which the leaf

  is inclined towards the interior of the room around a horizontal axis

  zontal located at the lower end of the leaf. The bascu-

  the leaf, from the closed position to the tilting position, is ensured by the locking linkage of which is indicated in FIG. 1 the closing lugs 6 engaging in the closing plates 7, and by the central closure with actuating lever 5. This is inclined by approximately 30, from the closed position I to the ventilation position II. For that, we rotate,

  through the rods actuating the rod-

  locking arm, two spacing arms 12, arranged concealed in the upper gap of the leaf and hinged on the one hand, to the frame, and on the other hand,

  position of Figure i to that of Figure 2.

  The guiding of the leaf 3 on the frame is provided by two rails, namely an upper slide 9 and a lower rail 10. The two slides are placed, for example screwed on the inner surface of the frame. The two slides 9 and 10 are advantageously formed of

  bar material that can be cut at will

  desired. In the upper slide 9 engages the end of the two spacing arms 12 which is located towards the frame and the adopted disposition is such that

  this commitment remains in any position of the leaf 3.

  On the short lower slide 10, between the fixing and abutment brackets 15, a wide carriage 11 on which the lower end of the leaf 3 is supported in each

of his positions.

  The locking linkage has at the bottom of the leaf locking lugs 6 which, in the closed position and in the tilting position of the leaf, engage in the closure plates 8 and secure the leaf in this position. Only when the operating lever 5 has been brought to position III, the tenons

  6 are aligned with side windows.

  through which they can exit when the end of leaf 3 moves perpendicular to the

  plan of the frame starting from the position of figure 1.

  The carriage 11 is formed of a profile that can be cut in a simple way to the desired length. The profile

  is completed by two running gear 28 at the ends.

  These undercarriages each comprise a boundary portion

  guide 29 in which is permanently housed

  On the upper side, a guide path 13 is provided for rollers for moving the lower end of the leaf perpendicularly to the plane of the frame. At the guide portion 29 is rigidly connected a core 31 which can be inserted on the front side into a profiled chamber 30.

  of the carriage profile and can be locked in the posi-

  inserted by two locking screws 38 (Figure 4). A profiled core 31 is integrally connected to the carrier portion of the axis of two support rollers 32, 33 spaced apart.

  one of the other. Each support roller has a circumference

  In this embodiment, the rollers may each rest on two guide ribs 34 and 35 of the lower slide 10. The slide has a rear wing through which it can be screwed onto the inner surface of the frame. In addition to or instead of this screw connection, the slide can also be simply held between the abutment brackets 15 which have, on the one hand, a wing to screw them on the frame, and on the other hand, a soul which

  engages in the profile recess 36 at the bottom of the slide

  10. It is seen that the spacing of the guide ribs 34, 35 and correspondingly the spacing of the support rollers 32, 33 are large, so that the carriage 11 rests on the slide 10 in a manner safe, which excludes tipping. The essential parts of the trolley and the rail are sections that can be cut to the exact length.

  The leaf rests in each of the guide ways

  13 of the undercarriages 28 by rollers 22 which are mounted on a bearing support, 20, about an axis 21 parallel to the frame. The bearing bracket surrounds the lower edge of the leaf and can be screwed firmly to both adjacent surfaces. The rollers 22 engage constantly

  in the guide 13, regardless of the position of the leaves.

  Each roller has an inner hub 25 provided with a recess - flattened on one side. In the recesses 26 of the two hubs 25 freely fit the ends of a rigid shaft 23 which has a plate 24. In this way, the two rollers are rigidly connected to each other with respect to the torque. Thanks to this, when the leaf is pulled from one side towards the interior of the room, for example by the handle 5, the leaf rolls outwards with one block, without torsion.

  neither warping, in the guide grooves 13.

  The rollers 22 and the corresponding parts may be covered externally, in the mounted position, by

a cover plate 27.

  As shown in Figures 1 and 2, the leaf 3 is normally slid behind the leaf 2 so that starting from its closed position, it is slid sideways in one direction. If the leaf 2 is a rotating leaf and if the frame does not have an amount between the two leaves, it may be advantageous or necessary, to open or clean the leaf 2, to first slide a little laterally the leaf 3 in opposite direction, so to the right of Figure 1, so that the leaf becomes free for movement. In this case, the rail 10 may have an appropriate extension to the right and an interlocking lock which can be triggered

  manually, which normally prevents the leaf 3 from sliding

  to the right of Figure 1 but which, after

  allows such sliding a small distance.

  In Figure 4 the iron plate is shown

  lower level 8 in plan, and the three possible positions

  I to IIIa of the locking pin 6 in the plate 8.

  FIG. 4 further shows the mounting position of the closure plate 8. In addition, the closed position I, the tilted position II and the sliding position

often used.

  Each spacing arm 12 is articulated, on the one hand, to the leaf and coupled to the actuating rod 45, so that when the rod 45 is slid, the spacer arm 12 can be pivoted by the closed position of FIG. 5 at the tilting or opening position and in the opposite direction. The spreader arm is normally concealed in the gap of the leaf as the

  shown in Figure 5. To facilitate assembly and deco-

  gate leaf, the spacer arm is in two parts,

  the two parts being connected to one another in a

  chable in the region located between the ends of the arm there 2489876

  as shown in Figure 6.

  An important characteristic lies in the fact that each spacer arm has between its ends a recess which is clearly seen in Figures 5 and 6. This recess has a Z-shaped section. This recess guides the spacer arm to the housing. outward and upward, from its region 43 located in the gap of the leaf, to the region 41 at the end of which is disposed the roller which engages constantly, that is to say in all position of the leaf 3, in the rectilinear rail 9 fixed, in particular

  screwed to the inner surface of the frame. The decreasing part

  is indicated at 42 while Part 43 at

  leaf is again downward in its direc-

  longitudinally, starting from the junction plane with the other part, to be at the junction point with the actuating rod 45, in the plane above the cover slide 46. The only machining of the profile of leaf 3 consists in milling a small recess 50, indicated in Figures 1 and 5 and for housing the upright wing 42 of the unhooked portion when the leaf is in the closed position shown in the

figure 5.

  Figure 7 shows an example of modified execution.

  Here, on the rail 10 is provided, at the end located before the closing position of the sliding leaf, a forced guide 51. This serves, when the leaf is again sliding in front of the leaf opening, to push from

  forced the lower end of the leaf to the posi-

  closure without this requiring attention

special.

  Forced guidance 51 is a guide portion disposed on the rail 10 and having a curved guide groove 57. This has an entrance section turned

  in the sliding direction and a guide section

  pendicular to the plane of the frame, these sections being connected by a continuous transition. On the bearing support 52 of the roller 22 of the leaf is provided a guide pin or a guide roller 56, facing downwards. It enters the entry portion of the forced guide 57 when

12 2489876

  slide the carriage to the left of Figure 7. As a result of this sliding movement, the guide roller 56 is guided perpendicular to the plane of the frame, towards the closed position. The roller 22 rolls in its transverse guide 13, in the direction of the position

  closing or towards the tilting position.

  Since the roller 22 is forcedly coupled to the end shown of the leaf, to the other roller or to the other rollers, in the region of the other end of the leaf, by the shaft 23, the other end leaf is

  thus forced to the position of

  to the closed position. He is particularly

  advantage of using forced guidance 51 in combination with

  its with the forced coupling in rotation of all the

rollers 22, by the shaft 23.

  In the example shown, the forced guide 51 forms, in the position shown, the normal stop limiting the sliding movement of the carriage so that, when the carriage or parts thereof abut against the forced guide 51, the leaf is exactly in line with the opening of the frame. The neighboring leaf, non-sliding, can not then be opened for cleaning if there is no central fixed amount 11, because the sliding leaf then prevents the opening of the neighboring leaf. For this case, it is possible to raise the forced guide 51 starting from the position of FIG. 7, so that one can

  beyond the alignment position on the opening of the frame, so that the neighboring leaf becomes free for opening. In the raised position, the forced guide 51 also forms the limit stop of the movement

  extended sliding of the sliding leaf.

  It should be noted again that a screw 53 of the bearing support 52 engages in a recess 54 on the front side of the carriage 11 and thus secures the leaf by preventing it from lifting relative to the carriage. The cart itself is

  prevented from lifting-thanks to the fact that the edge 55 of the

  riot engages under wing or protruding soul 60. It takes
