Description

The invention relates to a concealed fitting, especially for windows.

For the purpose of opening windows or the like, i.e. to ensure the swiveling of Windows are usually provided with fittings for windows, the guide pins attached to the frame or pins and the wing parts located on the wing frame exist in the form of bearing sleeves. Such fittings have the disadvantage, however, that they are particularly closed Windows are visible, which is higher for windows Quality is undesirable. For this reason, windows partly with so-called concealed fittings equipped with the wing closed from the room side are not recognizable here. Such a covert Fitting is known for example from DE 38 43 680. Such a concealed fitting determines the look of the closed one Window not. However, if the window is opened, then they are between the window frame and the window sash located handlebars recognizable. There is also occasional the desire that windows be arranged with hidden Fittings opened over an angle of more than 90 ° like with windows with conventional fittings, consisting of guide pin and guide sleeve the case is.

DE 19 16 700 U has a concealed fitting specified, with one arranged on the frame Guide with one attached to the wing, with the guide in Engagement guide element that is in the form of a has curved arc-shaped rail and on the wing is mounted by a mounting plate near the fold so that the wing-side end of the arcuate section of the Guide element meets the fold of the wing, wherein the guide has a guide slot for slidable reception contains the guide element and inserted in the frame is, the guide slot a to the shape of the Guide element has a customized profile. The mounting plate assigned to the frame cannot be done easily insert laterally into the frame, but is in to adopt a direction parallel to that Frame that defines the opening. The leadership extends beyond the frame towards the building and requires a corresponding opening to be kept clear in the masonry. The axis of rotation runs with this fitting of the guide element or the guide within the transverse to Door opening trimmed frame.

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 arched in this curved guide part to be inserted against 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 Aus. savings are provided that the arcuate guide elements elements can be used.

The invention is therefore based on the object of concealing one to create arranged simply constructed fittings, which is the opening of a window over an angle of more guaranteed as 90 °, while in the closed state of the wing no hinge 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, slanted and tilting windows in wooden and plastic version are used and replaces 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 joint unit, which is used to replace conventional window or door hinges. 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.

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 is on the inside Fold 10, for example at the lower corner of the casement an example L-shaped mounting rail 11, which in a known manner along the vertical running fold on the one hand and the lower horizontally running fold on the other hand be attached can and a guide member 12, which in turn extends only in the horizontal direction and a base section 12a and a part-circular shape extending section 12b. The part circular Section 12b begins its part-circular Course with closed window sash 2 where practically the fold 5 is defined on the window frame 1, as Figure 3 shows. Between the foot section 12a and the part-circular section 12b is thus located one essentially at a 90 ° angle to the foot section 12a extending in the direction of the window frame 1 Guide element section 12c, which then of the part-circular section 12b is followed. The Section 12b is thus in compliance with section 12c an obtuse angle of, for example, α = Set at 120 °. Reference is made in detail to FIG. 3.

In the illustrated embodiment, the curved portion 12b a length by a An angle of approximately 95 ° is defined by what is present Space or the width of a designated 14 Leadership is determined.

The guide 14, for example in the form of a Cylinder, is inserted into a cylindrical bore, which is milled into the window frame 1, namely in Area of the fold 10, as shown in Figure 3.

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

The guide 14 defines one in the plane of the Fold 10 lying approximately rectangular curved Slot 18 through which the guide element 12 is inserted is.

The guide 14 largely closes with her outside facing surface with the plane of the fold 10 from.

Figure 4 shows the frame 1 and the wing 2 in a position in which the wing 2 is open and thereby over an angle of slightly more than 90 ° stands for frame 1. From Figure 4 it can be seen that the Window sash 2 around a pivot point designated 16 or pivotable about an axis of rotation designated 16 is. The axis of rotation 16 is outside the Window frame 1 and with the sash 2 open between the frame 1 and the wing 2 approximately on the in Figure 4 position shown. To this extent it is express refer to Figure 4.

The guide 14 is in the illustrated embodiment sunk in wing 1 and by the viewer only recognizable from the direction of the fold 10.

With a pure rotating window are in Distance from each other at least two such Fittings such as those used in connection with FIGS. 3 and 4 are described while with a tilt and turn window the upper fitting is essentially the connection has the construction described with FIGS. 3 and 4, however, the foot section 12a on another Fitting part in the form of a handlebar or the like is attached, which is displaceable in relation to the window sash 2 is to enable the tilt function.

Figure 5 shows a plan view of the guide 14, the represents a preferred embodiment. This Top view shows that the cylindrical guide one contains arcuate slot 18 which is milled or is manufactured in a different way. The guide 14 is so in the frame 1 inserted that the slot 18 vertically runs and consequently the curvature of the slot 18 runs in the horizontal plane. In this way the management of the essentially horizontal, curved guide element 12 accomplished.

To inadvertently remove the guide element 12 from the guide 14 and the To prevent slot 18 can be at the end of the section 12b a vertically extending limiting pin 19 or the like can be provided, which in Figure 3 is indicated and either on the top or downward facing surface of section 12b is trained. Accordingly, there is a stop in the Guide 14 provided, designated 20 in Figure 5 and prevents the guide element 12 over the stop 20 in Figure 5 to the right becomes. Located in the area of the stop 20 the entrance opening, which is explained in the above Level of the fold 10 lies.

This pin 19 serves as a stop element and prevents the guide element from sliding out unintentionally 12 from the guide slot 18 of the Guided tour 14.

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

The invention concealed fitting is advantageously for windows, doors or the like made of wood or Plastic used in which the frame and Wing parts are made of solid wood and therefore one secure attachment on the one hand and integration enable by milling the fitting on the other hand.

In the fitting according to the invention Rotary motion 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 1 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.
