Description

The invention relates to a concealed fitting for Windows, doors or the like according to the preamble of the claim 1.

For the purpose of opening windows or the like, i.e. to ensure the pivoting of windows For windows, fittings are usually provided, which consist of guide pins or pins attached to the frame and the wing parts located on the sash frame in the form of bearing sleeves consist. However, such fittings have the disadvantage that that they are particularly visible when the window is closed are what is undesirable in higher quality windows. Out For this reason, windows are partially covered with so-called arranged fittings equipped with the sash closed cannot be seen from the room side. Such one Concealed fitting is for example from DE 38 43 680 known. Such a concealed fitting determines the look of the not closed window. However, if the window is opened, then they are between the window frame and the window sash located handlebars recognizable. In addition, there is occasionally Wish that windows with concealed fittings over an angle of more than 90 ° can be opened like this for windows with conventional fittings, consisting of a guide pin and guide sleeve it does.

A hinge with an essentially circular segment-shaped design is known from DE-1 916 700 U1. This hinge consists of a circular segment-shaped receiving part, which with the help of two fastening plates can be fastened to a door frame, such that the circular segment-shaped, door frame-related part through the butt-jointed door frame parts must be and thus introduce over the corner of the door frame is, due to the length of the circular arc segment Cutouts on the surface of the door frame facing the wall are to be provided. To enable the door leaf to be detached, is the further circular arc segment with a hammer head Fitting provided in a corresponding flange-like running recess of the door leaf must be locked. One disadvantage of the known construction is that in the area of the door frame the guide unit the door frame protruding and through the use of two Mounting plates in the door frame must be used that recesses must also be provided in the door frame on the wall side, and that finally the wing-side guide unit as well is complex. Furthermore, both circular arc segments stored against each other via roller bearings or the like, what the construction effort and the assembly effort essential elevated. While on the one hand invisible when the door is closed Door hinge to be created is disadvantageous on the other hand leading out of the door frame levels is required. In addition, the length of the arcuate guides is designed so that an angle of almost 180 ° is covered, which leads to Difficulties in installing the hinge leads.

From US-1 648 781 is also made of arcuate components compound joint known in which the two parts to be connected to one another in an articulated manner are each arcuate Guide holder included and an arcuate in this Arc-shaped guide part to be used for guide receptacles is to be provided. The design effort of this known joint is comparably high and the assembly is extraordinary difficult. For the installation it is necessary that such recesses be provided that the arcuate guide elements can be used.

The invention is therefore based on the object of concealing one to create arranged simply constructed fittings or handlebars, which is the opening of a window over an angle of more guaranteed as 90 °, while in the closed state of the wing no handlebars or band parts between sash and frame are recognizable or visible.

This object is achieved by the claim 1 specified features solved.

Further embodiments of the invention result from the subclaims.

The invention provides a concealed fitting that basically consists of two parts, namely a tour with Guide slot and a guide element. Preferably here the guide is inserted into the frame while the guide element is attached to the wing. The guide element has part-circular course and engages in the also part-circular extending guide slot of the guide. On this ensures that, depending on the size of the Partial circle opened the window over an angle of more than 90 ° can be. The fulcrum is advantageously this Fitting, consequently the wing during its opening is only shifted around the specified pivot point, however is not moved outwards or inwards relative to the frame.

The fitting according to the invention can advantageously also Arched, segmented, sloping and tilting windows in wooden and Plastic version are used and replaced the usual Door or window hinges in the form of pin and wing parts (Bearing sleeves).

The invention thus creates a fitting in the form of a Swivel unit, which is used to replace conventional window or Door hinges are suitable. This fitting sits between the Casement for example of a window and the associated Frame and is when the window is closed or when the window is closed Do not see the door. As with windows or doors usual, preferably at least two such fittings provided at a vertical distance from each other.

The fitting according to the invention consists of a first guide receiving part, which is in the form of a cylinder or Blockes in a cylindrical or cuboid recess in the Window frame is used, the recess on one level is formed on the inside and practical inserted laterally into the frame from the opening of the frame becomes. The counterpart with the arched band sits by means of a plate or the like on an end face on Fold of the wing. Both parts have an arcuate course over a radius of less than 180 °, which is the design overall influenced in their simplicity.

The invention creates a fitting in the frame side as with normal fittings, simple milling are in order to be able to mount the guide receptacle while on the wing side the guide bands are attached by simply screwing them on can be. The fitting according to the invention is suitable also for use with tilt doors, tilt windows or the like, in this case the upper fitting with the Issuing mechanism is connected that the arcuate Guide element not by means of a plate on the fold of the Wing, but over an angle or the like with that Issuing mechanism is releasably coupled.

There is a significant advantage of the fitting according to the invention in that the center of the circle of the arcs of the Guide element and the radius determining the guide receptacle on or near the vertical edge of the wing, defined by the closest fold on the room side is. As a result, the radius is also comparatively small, which is a Miniaturization of the fitting made easier.

Below is a preferred embodiment of the invention Fitting based on the drawings for explanation described further features.

The fitting according to the invention is found particularly in windows Application. Figure 1 illustrates a window frame 1 and a window sash 2 opened with respect to the window frame 1, the window sash 2 over an angle of about 90 ° the window frame 1 is open. When using a known fitting, for example according to DE 38 42 680 is opposite the window sash 2 during the opening process the folds 3, 4, 5 of the window frame 1 in one moved an arrow 6 shown in the window opening, i.e. it is not exclusively circular Opening movement of the window sash 2. This has the consequence that the window sash 2 with its outer surface 2a over a predetermined Distance opposite, for example, the fold 3 in the direction the arrow 6 is offset. Such a movement of the window sash 2 is partially undesirable. Furthermore, the well-known Hardware the disadvantage that when the window sash 2 is open Fitting parts such as handlebars are visible, in FIG. 1 with 7 and 8 are indicated in the drawing.

The disadvantages indicated above are due to the inventive Fogging avoided. When opening the window sash 2 is the window sash 2 according to Figure 2 about a fixed pivot point or shifted and remains about a defined axis of rotation thus essentially in alignment with window frame 1, i.e. he in contrast to the representation according to FIG. 1, it does not move in the direction the arrow 6 of the folds 3, 4, 5 in the direction of Arrow 6 offset. In addition, as explained below, between the window frame 1 and the window sash 2 no Swiveling and simultaneous guidance of the window sash 2 ensuring the linkage arrangement is recognizable as soon as the window sash 2 is open. As can be seen from the description below results, is with the window sash 2 open Direction of the outer surface of the window sash 2 essentially only the guide element accessible as well as natural the attachment of the guide element to the Window sash 2.

Figures 3 and 4 show a preferred embodiment of the fitting according to the invention.

On the window sash 2 there is, for example, the inner fold 10 at the lower corner of the casement, for example L-shaped mounting rail 11, which in a known manner along the vertical fold on the one hand and the lower horizontal fold on the other hand attached can be and a guide member 12, which in turn extends only in the horizontal direction and from one Foot section 12a and a part-circular section 12b exists. The part-circular section 12b begins its part-circular course with the window sash closed 2 where the fold 5 practically defines on the window frame 1 is, as Figure 3 shows. Between the foot section 12a and the part-circular section 12b is thus in essentially at a 90 ° angle to the foot section 12a in Direction on the window frame 1 extending guide element section 12c, which is then separated from the part-circular section 12b is followed. The section 12b is thus on the section 12c while maintaining an obtuse angle of, for example α = set at 120 °. Reference is made in detail to FIG. 3.

In the illustrated embodiment, the bent portion has 12b a length defined by an angle of approximately 95 ° what is defined by the available space or width a guide designated 14 is determined.

The guide 14, for example in the form of a cylinder, is in a cylindrical hole is inserted into the window frame 1 is milled, in the area of the fold 10, as shown in the figure 3 shows.

Obviously, a polygonal can also be used as the guide 14 or oval part, e.g. made of metal, plastic or the like, be used.

The guide 14 defines a lying in the plane of the fold 10 approximately rectangular curved slot 18 through which the guide element 12 is inserted.

The guide 14 largely closes with its outward facing Flat with the plane of the fold 10.

FIG. 4 shows the frame 1 and the sash 2 in one position, in which the wing 2 is open and thereby over an angle of slightly more than 90 ° to frame 1. From figure 4 it can be seen that the window sash 2 is designated by 16 Pivot point or about an axis of rotation designated 16 is pivotable. The axis of rotation 16 lies outside the window frame 1 and with the sash 2 open between the frame 1 and the wing 2 approximately at the position shown in FIG. In this regard, reference is expressly made to FIG. 4.

The guide 14 is in the embodiment shown in the Wing 1 sunk and the viewer only from the direction of the fold 10 recognizable.

In the case of a pure rotating window, there is a distance between them at least two such fittings, as in connection are described with Figures 3 and 4, while in a turn-tilt window the upper fitting essentially the connection has construction described with Figures 3 and 4, however the foot section 12a on another fitting part in shape a handlebar or the like is attached, the ratio is to be moved to the window sash 2 to the tilt function enable.

Figure 5 shows a top view of the guide 14, which is a preferred one Embodiment represents. This top view shows that the cylindrical guide contains an arcuate slot 18, which is milled or manufactured in another way. The Guide 14 is inserted into the frame 1 so that the slot 18 runs vertically and consequently the curvature of the slot 18 runs in the horizontal plane. In this way the Guiding the essentially horizontal, curved Guide element 12 accomplished.

In order to remove the guide element 12 unintentionally to prevent the guide 14 or the slot 18 may end of the section 12b a vertically extending limiting pin 19 or the like can be provided, which in FIG is indicated and either on the up or down facing surface of section 12b is formed. Corresponding a stop is provided in the guide 14, which in Figure 5 is designated 20 and prevents the guide element 12 over the stop 20 in Figure 5 to the right is shifted. In the area of the stop 20 is the Entry opening, which is explained in the level of the Fold 10 lies.

This pin 19 serves as a stop element and prevents one unintentional sliding out of the guide element 12 from the Guide slot 18 of the guide 14.

In the fitting according to the invention it is essential that the Movement between window sash 2 and window frame 1 by one curved guide element 12 is controlled, which advantageously is designed in the manner of a pitch circle the associated guide slot 18.

In principle, the guide 14 can also be provided on the wing side be and the guide element 12 on the frame side, i.e. so one kinematic reversal of the described guide device is possible in principle, but according to the invention the described is Preferred embodiment. The invention conceals arranged fitting is advantageously used for windows, Doors or the like made of wood or plastic used which the frame and sash parts consist of solid wood and thus secure attachment on the one hand and integration enable by milling the fitting on the other hand.

In the fitting according to the invention, the rotational movement of the wing, i.e. in the course of the opening movement of the wing 2 the guide element 12 in a horizontal plane in relation relocated to the guide 14 out of the guide 14. When closing the window sash 2, the movement of the Guide element 12 in the opposite direction, i.e. in Horizontal direction into the guide 14.

The, for example, cylindrical guide 14 is of this type inserted in the frame 2 that the cylinder axis of the guide is aligned horizontally and the slot depth of the Slot 18 is aligned vertically.

From the above description it can be seen that the guide element 12 extends around the associated axis of rotation, wherein the axis of rotation is preferably in the vertical, but can also be horizontal. In the latter case the guides 14 may be inserted vertically into the frame.

Figures 7 and 8 show a preferred embodiment of the invention Fitting, the one in the upper area of a window existing fitting in connection with a tiltable Window is shown. The one at the bottom of a window Fitting is on the sash using a plate or the like attached such that the over a pitch circle extending guide element 12 laterally or horizontally Direction protrudes from the casement, as shown in the figure 7 emerges. The fitting shown in Figure 7 with the guide element 12 is on the top of a window or a door that is shifted into a tilted state can. For this reason, the guide element 12 with his Do not end on the casement directly on the side surface of the casement attached, but with an angle connection an opening rod 20.

As can be seen from FIGS. 7 and 8, the guide element 12 with its wing frame-side end or the foot section 12a outwards as far as possible opposite the casement arranged, d. H. in contrast to the representation according to FIG. 3 with the sash open, there is a continuous, curved course from the front of the casement in Direction to the window frame or frame 1. The figure 7 undetectable foot section 12a of the fitting that does not interact with the display linkage, i.e. on the casement is provided below, runs opposite the Embodiment according to Figure 3 in the opposite direction to Guide element 12b, d. H. Direction to the outside of the casement 2. The arcuate guide member 12b extends in the illustrated embodiment over an angle of about 135 °.

As can further be seen from FIG. 7, the frame 1 is corresponding Figure 3 is a guide 14 provided by a first arcuate curve 18 is defined for receiving the guide element 12b serves. In addition, one is at least partially arcuate extension 23 is provided, along which a 24 designated stop during the rotational movement of the casement 2 slides. The stop 24 is at the free end of the guide element 12 is provided and is in the illustrated embodiment away from the guide element 12, d. H. the stop 24 is opposite to the center of the circle of the guide element 12 the outer surface of the guide element pointing away from the center of the circle 12 provided. The recess 23 is accordingly not formed over the entire length of the guide slot 18, but only over a predetermined range, which the Defines the opening angle of the casement 2. The recess 23 consequently runs parallel to curve 18 with one to the curve 18 larger radius. The guide 14 is according to Figures 7 and 8 designed as a block that can be inserted into the frame 1 what purpose a corresponding recess in the frame 1 is to be made. The block 14 is preferably made of metal or plastic.

The guide element 12 is at least in terms of Figure 8 of the upper fitting on the window side with one pointing upwards Provided angle section 25, over which a mechanical Connection to the exhibition linkage indicated by the reference number 20 will be produced.

The fitting according to the invention thus serves as a handlebar for windows, Doors or the like opposite a frame.

According to the invention, the curved guide rail 12b has one square or differently shaped cross section, being to allow a relative movement with respect to the guide 14 Guide 14 also on this cross section contains curved guide receptacle 18. Form of the guide element 12 for the embodiment according to FIG. 7 and 8 substantially corresponds to the shape of an h. Considering the essentially part-circular design of the guide section 12b.

The center point also lies in the embodiment according to FIG. 7 or 8 of the radius for the guide elements on or near the with 16 designated axis, which is closest to the room side lying fold is determined and by the front outer edge of the wing in this area, as shown in FIGS. 4 and 7.
