Abstract

The locking bars (6) are mounted slidably in C-shaped receiving grooves (3) of the leaf (1). The locking bars (6) are of U-shaped cross-section and have lateral legs (7) which are each equipped with a side groove (8) extending over the entire bar length. Each side groove is limited by a lower web of the thickness S1 and an upper web of the thickness S2. The clear height of each side groove has the dimension N. The clear height H1 of the receiving groove (2) is greater than the constructional height H2 of the locking bar (6) by the amount of the web thickness S1. The receiving grooves and the associated locking bars (6) are of identical cross-section on all the spars of the leaf. The receiving grooves (3) have inwardly extending edge strips (5), the constructional height H3 of which is a little smaller than the clear groove height N of the side grooves. There are two installation positions I or II for the locking bars. In the installation position I, the side legs of the locking bar are supported on the bottom face (4) of the receiving groove (3), whilst in the installation position II the locking bar (6) is mounted slidably on the edge strips (5) of the receiving groove (Figure 1). <IMAGE>

Description

The invention relates to a window or a door, preferably with a plastic frame, with a locking bar fitting having only a hand lever handle, the locking bars of which are slidably mounted in C-shaped receiving grooves of the sash frame.

A window or door of this type is known (EP 0 056 484), in which the wing is equipped with a faceplate fitting. These faceplate rail fittings are prefabricated installation units which have a faceplate on which the locking bar provided with locking pins is mounted so as to be longitudinally displaceable. The locking pins extend through elongated holes in the face plate, which has a cover and fastening function. The faceplate rail unit on the handle side is equipped with a gearbox that is operated via a hand lever.

These faceplate mounting units have, for connecting to other fitting units, such as corner deflections, in each case form-fitting coupling devices which can be cut to length over a certain range, for example 100 mm, so that they can be adapted to different window dimensions. However, this adaptability is not sufficient for the large number of different window sizes that a large stock of faceplate installation units in the window and door manufacturing companies is required.

In the faceplate fittings, the faceplate and locking bar are designed as stamped sheet metal parts in order to achieve the lowest possible installation height. All forces occurring on the locking elements must be absorbed by the locking bar, which transfers these loads to the faceplate. High surface pressures occur in the contact area, which means that the fitting is stiff.

The faceplate is generally accomplished by screws or other loading festi ^g ungselemente of the sash frame fixed to the plastic profile. These fasteners must absorb the loads. In the case of plastics, however, the transferable surface pressure is low, so that in the known embodiment there is a risk of the fastening elements being overloaded. In addition, lubrication is absolutely necessary for the faceplate fittings due to the friction pairing steel on steel. Relubrication of such faceplate rail fittings in the installed state is difficult, however, since the surfaces to be provided with lubricating grease are located in an area which is covered by the faceplate and is not accessible from the outside. In the known aluminum window and door systems, fitting receiving grooves are provided, in which the locking bars are completely guided, the locking bars filling the receiving grooves. The locking rollers are inserted into the U-shaped or C-shaped locking rods so that the locking forces acting on the locking rollers are also transmitted to the frame profile via the locking rod. In addition to tolerance additions, which are noticeable as gear play, lubrication of the sliding surfaces is required for perfect locking bar function.

Another disadvantage of the known locking bar fittings arises in the upper horizontal area of the sash in the tilt and turn version, in which the opening device is provided. The display devices are anchored in the fitting receiving groove of the upper casement spar for reasons of space, so that a specially designed locking bar is then required for the long-band locking of the display device. A housing is used to guide this locking bar, on which the articulation points of the scissor arms are also provided with respect to the casement.

The invention has for its object to design a window or door of the type mentioned in such a way that a locking bar version can be used in the area of all spars of the casement and the associated various fitting parts can be connected or combined with this locking bar in such a way that closing and Locking forces are introduced directly into the casement profile.

This object is achieved by the features of the characterizing part of claim 1.

In the locking bar fitting according to the invention, the faceplate, its fastening elements for fixing to the sash frame spar and the means for slidably mounting the locking bar adjacent to the faceplate are eliminated. The U-shaped locking bar used is either slidably mounted on the bottom of the receiving groove of the respective casement spar or slidably on the edge strips of the receiving groove. If other fitting parts have to be connected to the locking bar, the connection is made by a simple plug-in connection, in which a pin of the fitting part is inserted into a hole in the locking bar. These fitting parts are also guided on a wall or on the edge strips of the receiving groove. Power is transferred from the hardware components directly to the sash frame via these guide surfaces. The locking bars and the fitting parts can be made of plastic, so that there is no need to lubricate these parts during operation.

Further characteristics and features of the invention will become apparent from the subclaims and the following description of an _'embodiment.

The sash 1 and the frame 2 of the embodiment shown in the drawings consist of plastic hollow chamber profiles which are mitred in the corners and welded to one another. The sash 1 is circumferentially equipped with a C-shaped receiving groove 3, in or on which locking bars and other fitting parts are slidably mounted or fixed. The receiving groove has the same cross-section in the area of all the spars of the casement and has a clear height H between a bottom surface 4 and inwardly projecting edge strips 5. The locking bar 6 assigned to the receiving groove 3 is U-shaped in cross section. The legs 7 of this locking bar have an outwardly open side groove 8 which extends over the entire length of the bar and has a clear height N. Each side groove is delimited by a lower web with the thickness S1 and an upper web with the thickness S2. The clear height H 1 of the receiving groove 3 is greater than the structural height H _{2 of} the locking bar 6 by the web thickness S1. The edge strips 5 of the receiving groove have a structural height H ₃ which is a little smaller than the clear groove height N of the side grooves.

Due to these designs and dimensions of the locking bar and the receiving groove, it is possible to slide the locking bar in two operating positions in or on the receiving groove. The first operating position is denoted by 1 in FIG. 1. In the operating position I, the locking bar 6 assumes the position drawn in solid lines. It is supported with its legs 7 on the bottom surface 4 of the receiving groove and is slidably supported relative to the bottom surface. The bottom 8 of the locking bar faces the opening of the receiving groove, which is delimited by the edge strips 5.

II with the second possible operating position of the locking Stan ^g e is referred to. 6 In this operating position, which is shown in dash-dotted lines in FIG. 1, the edge strips 5 engage in the side grooves of the locking bar 6. The locking bar is slidably mounted on these edge strips. The bottom 8 of the locking bar lies within the receiving groove 3.

In the rotary tilting version shown in the drawings, the locking bars 6 in the receiving grooves 3 of the lower and the upper horizontal wing frame spar 9, 10 and the vertical hinge-side wing frame spar 11 assume the operating position I, in which the lateral legs of the locking bars on the bottom surface 4 of the receiving groove support and are slidably mounted against this surface, while the locking bar in the handle-side sash frame occupies the operating position 11 and is thus slidably mounted on the edge strips 5 of the receiving groove. In the tilt and turn window shown in the drawings, two designs of locking pieces are used. One design is shown in FIGS. 12 and 13 and the second in FIGS. 14 and 15.

The locking piece 12 shown in FIGS. 12 and 13 has a anchorages ^g szap- fen 13 which is inserted into a bore of the associated tie rod 6 and is formed as a hollow pin, in the illustrated embodiment. The locking piece 12 is also provided with a plate 14 which is equipped with side grooves on the long sides. The edge strips 5 of the receiving groove 3 engage in these side grooves, so that the locking piece 12 is slidably mounted on the edge strips 5 of the receiving groove. On the side opposite the anchoring pin 13, a bearing pin 16 is provided on the locking piece, on which a metal roller 17 is rotatably mounted. This metal roller has at its upper edge a recess 18 into which the plasticized material of the journal 16 is molded, so that after cooling and the associated shrinkage of the material, despite the positive connection between the journal and the metal roller, this is necessary for the rotatability of the metal roller necessary play occurs compared to the bearing journal.

From the sectional view of FIG. 12 it follows that the bearing pin 16 has a stepped cylindrical outer contour and the inner contour of the metal roller 17 corresponds to this outer contour of the bearing pin.

The second, used design of a locking piece 19 according to FIGS. 14 and 15 has a rectangular plate 20, which is equipped in the region of its lower longitudinal edges with sliding runners 21 and is slidably supported on the bottom surface 4 of the receiving groove 3 with these runners. A bearing pin 22 extends from the plate 20 on the side facing away from the runners 21 and is equipped with a metal roller 23 at its upper end. The design and design of the journal in the area of the metal roller and the design of the metal roller correspond to the exemplary embodiment according to FIG. 12.

14 and 15 is used in the receiving groove 3 of the handle-side vertical wing frame spar. The bearing pin 22 is through a hole in the bottom of Rie ^g Elstan ^g e 6, which takes the operating position I, plugged. The bearing pin 22 extends through the space of the locking bar, which is delimited by the legs 7 and has the distance B between the legs. In an advantageous embodiment, the journal 22 has a diameter which corresponds to the internal dimension B of the locking bar. This ensures that when installing the locking bar according to operating position II, the bearing pin 22 is held transversely to the locking bar at the entire height H ₂ when the locking forces occur and can be supported.

The locking piece 24, which is assigned to the locking pieces 12 and 19 and fastened to the frame, is shown in FIGS. 16 and 17. It is equipped with a mounting base 25 which has a push-through hole 26 for a countersunk screw which is screwed into the frame. On the mounting base a Rie ^g elschlitten 27 is arranged, which is movable by means of an eccentric 28 along a slide guide 29 which extends transversely to the longitudinal axis 30 of the striker. The eccentric 28 is provided with a head plate 31 which has a slot 32 for inserting an actuating tool. The locking slide 27 is fork-shaped on the entry side for the metal roller 17 and 23 of the locking piece 12 and 19, respectively equipped with locking surfaces 32.33. The position of these locking surfaces can be adjusted using the eccentric. The non-releasable connection between the mounting base 25 and the locking slide 27 is achieved by the rivet head 34 of a cylindrical pin 35 which is mounted in one piece with the eccentric 28 and rotatably mounted in a bore 36 in the mounting base 25.

To actuate the locking bar fitting, a hand lever handle 37 is provided, which is rotatably mounted on a housing 38, which is fixed to the sash 1. Via the hand lever handle 37, an adjusting slide 39 is actuated, which extends through a recess in the sash frame into the receiving groove 3 and there engages positively around a driver 40 which is coupled to a locking bar 6 which is slidably mounted on the edge strips 5 of the receiving groove. The structural details of the driver 40 result from FIGS. 18 and 19. The driver 40 has a lateral pin 41, which is inserted into a hole in the bottom 8 of the locking bar 6. The coupling between the adjusting slide 39 and the locking bar 6 is achieved by this plug connection. The driver 40 has a slider 42, which is supported on a lateral groove wall. The slider is rectangular in plan and can be provided with a runner 43 which bears against the wall of the receiving groove 3. The driver 40 with its pin 41 and the slider 42 and the runner 43 is preferably made in one piece from plastic.

At the lower end of the locking rod on the handle side, a finger lock 44 can be fastened, which engages in a recess 45 of an angular bearing part 46 fastened to the frame 2 in the tilted position of the wing. The attachment end 47 of the fin ^g erriegels engages the inner groove of the locking bar. 6 Its width corresponds to dimension B of the inner groove of the locking bar. The attachment end is equipped with an anchoring pin 48 which is inserted into a hole in the bottom of the locking bar. The middle part of the finger drive is provided with side grooves 49, which are connected to the side grooves of the locking bar 6 are aligned so that the side strips 5 of the receiving groove 3 engage in these side grooves 49.

4, the finger latch 44 is shown in the closed position of the wing.

At the handle-side lower end of the casement an angular support part 50 made of plastic is provided, which is supported during the tilting movement of the casement on the lower horizontal leg of the bearing part 46 fixed to the frame.

2 and 3, the opening device of the tilt and turn window is shown. This opening device has a scissor arm 51 which is articulated on the side facing the frame 2 by means of a pivot bearing 52 on the frame and the other end of which is connected in an articulated manner to a slide 53 which is slidably mounted in the region of the edge strips of the receiving groove of the upper horizontal casement frame 10 is. The opening device also has an additional link 54, which is articulated on a slide 55. This slide is also slidably mounted on the edge strips 5 of the receiving groove of the upper horizontal wing frame spar and can be adjusted by means of an adjusting screw 56 relative to a bridge 57 fixed on the wing frame spar. The bridge 57 is equipped with a nose 58 which is inserted into a recess in the upper casement spar. The bridge is fixed using screws 59.

Since the slides 53 and 55 are slidably mounted in the area of the edge strips 5 of the receiving groove of the upper horizontal casement spar, the locking bar 6 can be arranged in the operating position 1 below these sliders and coupled to a locking piece 61 on the side facing the upper hinge-side corner deflection 60, that extends into the area of the upper hinge-side corner deflection 60 and engages behind a pin 62 in the rotational and closed position of the wing, which is fastened to the scissor arm 51.

The locking bars can be made from a glass fiber reinforced plastic.

The locking bar arranged in the receiving groove (3) of the upper horizontal casement spar 10 is coupled at the end facing the handle-side upper corner deflection (63) to a spring band (64) of the corner deflection, namely by means of a pin (65) which extends through a bore extends in the bottom of the locking bar (6).
