Description

The The invention relates to a hinge according to the preamble of the claim 1.

A hinge - also called fitting or in particular shower door fitting - the aforementioned genus is known from the utility model DE 20 2008 000 147 U1 ,

shower stalls increasingly no longer rectangular, but increasingly common a polygonal floor plan. The interior aesthetics or structural conditions require this. Shower cubicles become individual created by craft enterprises based on standardized, industrially produced Resort to components. To keep the warehouses small and the To keep quantities large, exists on the part of Manufacturers and distributors have an interest in the fittings to flexibly perform the hinging of entrance doors, as one and the same hinge for different angles between the closed door and the adjacent wall are usable.

Known angle adjustable door hinges were among others by the EP 0 599 255 B1 , the EP 0 822 309 B1 , the DE 199 54 922 A1 and through the DE 103 13 962 A1 , The hinge bands enumerated above have in common that they have a radially guided to the belt axis locking member which locks the two tabs in the zero position - ie with the door closed - each other gently so that the door closes better and is held exactly in the seal. The radial guidance of the locking member requires that these shower door fittings apply relatively thick, which is detrimental to the aesthetics of a high-quality shower cubicle. The taste of the times demands particularly flat fittings in the glass door area and in the shower cubicle construction.

Another way is proposed as the generic DE 20 2008 000 147 U1 one. This discloses a hinge in which the zero position is not realized by a radially moving locking member, but by axially arranged mutually sliding Hubkegel. The Hubkegelpaarung represents a cam gear, which partially converts the rotary pivotal movement of the wing in a translational lifting movement in the direction of the belt axis. By the lifting movement of the wing is raised when swinging up and gets so in an unstable pivot position, in which he stores potential energy. As soon as the user lets go of the hinged door, the wing releases this potential energy and returns to the stable zero position, where the door is closed. The hinge thus has an integrated closing function. Another advantage of the superimposed lifting movement is that when opening the door leaf is lifted out of the bottom-side seal, or is pressed in when closing. As a result, the sealing seat of the door leaf is improved at the threshold of the entrance door to the shower cubicle.

The Adjustability of the prior art fitting is done with the help of a radially aligned to the belt axis clamping screw, with which the lifting cone in terms of the angular orientation of their functional surfaces Be fixed relative to belt axis: By aligning the lower Hubkegels relative to the belt axis will be the zero position between the two Adjusted lobe and this fixed with the radial clamping screw. This has the advantage that the zero position adjusted at any time but this benefit is not more practical Meaning, since shower cubicles in case of a change of residence regularly not to move with and be built differently at the new place of residence. It predominates a disadvantage of the radial clamping screw, namely the possibility the penetration of water into the threaded hole of the screw. this leads to At best, lime deposits. Furthermore This hinge assembly is constructed comparatively complicated. A final disadvantage is the fact that the restoring force depending on the weight of the door leaf is. A light wing gets inside due to friction the Hubkegelpaarung may not be optimal in the Zero position returned.

in the In view of this prior art, the present invention the task is based on a hinge of the type mentioned so on, that it is simpler, slimmer builds and has no radial clamping elements. At the same time one should infinitely variable adjustability of the zero position may be permitted.

Solved This object is achieved by a hinge with features of the claim 1.

A basic idea of the present invention is to provide a zero position setting a once to be mated, positive connection between the second lifting cone and its associated wing flaps. The positive connection is realized via a knurl arranged on the hub, which engages positively in a bore of the wing flap. Accordingly, the bore must have a small undersize relative to the knurl, so that this functional surface digs into the wall of the bore and fixes the second lifting cone rotationally fixed to the wing flap. This results in a positive shaft / hub connection between the second lifting cone and wing flaps, which determines the angle of the zero position at the moment of joining. Since the shaft / hub connection between the second lifting cone and the wing flap is virtually insoluble, the zero position be re-adjusted only to a small extent. It does not require any radial clamping means, but disappears completely inside the wing flap. This reduces the space and avoids water seepage.

In In its simplest form, the lifting cone arrangement realizes a single-stage, linear transfer function, as in the prior art known. This means that the implementation of the swivel angle in the stroke is in a fixed, proportional ratio. A preferred embodiment of the present invention, on the other hand, make the Hubkegelpaarung so that they have a transfer function realized, which is a starting from the zero position first linear Section and an adjoining second linear Section, wherein the slope of the first section clearly greater than that of the second section. This means that the wing at the beginning of the pivoting movement is raised first, while in the further Course of the opening stroke of the hub formed weaker is. This has the advantage that the door leaf at the beginning of the pivoting movement very steep from the threshold seal is highlighted, which protects the seal. After leaving the Seal becomes flatter the slope of the transfer function, to lower the actuating forces.

In Another preferred embodiment, the lifting cone by means of a spring arranged on the belt axis against each other biased. The energy stored in the spring increases that Potential of the wing flap located in the unstable pivot position. This will ensure that the door leaf even then reliably swings back to zero position, if it is a light wing. The additional Restoring force is applied by the spring. In this Embodiment, the hinge works independently reliable from the sash weight.

advantageously, the band axis is at one end with a head and on the threaded at the other end. On or in the thread then a stop element is screwed, so that between stop element and head the flaps, the spring and the Hubkegelpaarung held axially are. This structure allows for a convenient installation, in the over the tightening of the thread, the knurl of the second lifting cone pulled into the bore and thereby the Positive connection is produced. In addition, lets Such a connection can easily solve the door if necessary. Finally allowed the screw the adjustment of the holding force by adjusting the spring preload.

The according to the invention can be everywhere be used; Their preferred location is the glass industry and especially the shower cubicle construction.

The The present invention will now be described with reference to a preferred embodiment be explained in more detail. For this show:

1 : Perspective view of the front of the hinge, connecting means exploded;

2 : perspective view of the back of the hinge;

3 : Exploded view of the hinge without connecting means;

4 : Graphical representation of the transfer function compared to the second lifting cone;

5 : Installation situation from above, zero position at 180 °.

6 : Installation situation from above; Zero position at 135 °.

The hinge according to the invention 1 includes a wall flap 2 and a wing flap 3 Both are over a ribbon axis 4 pivotally connected to each other. The wall lobe 2 is mounted on the stationary wall, while the wing flaps 3 is connected to the door leaf. The door leaf is thus with the wing flap 3 around the substantially vertical belt axis 4 swung. The ribbon axis 4 remains stationary within the pivot plane, but it moves axially up and down; later.

The 1 and 2 show connecting means 5 for attaching the cloths 2 . 3 on the wall or on the wing. In the in the 1 . 2 . 5 and 6 shown connecting means 5 These are adhesive zones known per se for attaching the flaps to glass walls or wings. Instead, the rags can 2 . 3 Also be equipped with known per se fasteners that allow a connection with tiled walls or the like. The connecting means 5 are not the subject of the invention and therefore will not be discussed further.

3 shows the functional structure of the hinge 1 , On the wall lobe 2 is a first lifting cone 6 immovably tethered. This first lifting cone 6 assigned is a second lifting cone 7 Both together form a Hubkegelpaarung 6 . 7 , which in principle represents a cam gear, which is a pivoting movement of the second Hubke gels 7 opposite the first lifting cone 6 in an axial stroke of the second lifting cone 7 implements. The implementation of this transfer function is carried out by means of cam surfaces a, b, c, which are helical around the axis of the Hubkegelanordnung 6 . 7 extend around. The cam surfaces a and b are symmetrically double in order to obtain a symmetric transfer function. This means that starting from a zero position o of the wing flaps 3 can be swung to the right and left and from there each returns to the stable zero position o.

The relationship between the design of the first lifting cone 6 and the resulting transfer function results 4 , Accordingly, the transfer function, starting from the zero position initially increases very steeply, with an angular travel of 15 °, a stroke of 73 mm has already been reached. This slope is achieved via cam surface a. This is followed by the cam surface b, which causes only 2 mm stroke over 75 ° Winkelweg. At a swivel angle Φ = 90 °, a total stroke of 5 mm ° is achieved. The values mentioned are an example and can not be transferred to all installation situations. When the total stroke is reached, the transfer function transitions to a plateau, which is formed via the cam surface c. On this plateau takes the second lifting cone 7 a stable position so that the door is open. Below 90 ° is the second lifting cone 7 always in an unstable pivoting position, from which he falls back into the stable zero position o. The potential that triggers the falling back, on the one hand from the potential energy of the wing over the stroke of a maximum of 5 mm and is reinforced by the in a compression spring 8th stored energy, which is compressed with increasing pivot angle Φ. At the in 3 The spring shown is a sleeve-shaped, foamed elastomer, which serves as a compression spring with "built-in" damping.The use of foamed elastomers as a spring member is known in locks from the DE 10 2004 049 547 B3 ,

To define the zero position is the second lifting cone with a knurl 9 Mistake. The knurl 9 is in a corresponding, coaxial with the belt axis extending in the wing flaps 3 introduced bore 10 pressed. The diameter of the hole 10 has opposite the knurl 9 a slight undersize, so that when pressing the knurl 9 into the hole 10 a positive connection between the second lifting cone 7 and the wing flap 3 arises. knurled 9 and bore 10 form a shaft / hub connection.

Pressing in the knurl 9 into the hole 10 of the wing flap 3 can with the help of the belt axis 4 done for this purpose at one end with a head 11 and at its other end with a thread 12 Is provided. On the thread is a stop element 13 screwed on, in this case a sleeve nut with countersunk head. Between the head 11 and stop element 13 the band axis runs 4 and thus seizes spring 8th , Wall lobes 2 with first lifting cone 6 and the dressing from the second lifting cone 7 with the wing flap 3 coaxially together. By tightening the thread 12 (For this purpose, the stop element with a hexagon socket 14 provided) becomes the knurl 9 into the hole 10 pressed and thereby established the positive connection in the desired zero position. In order not to accidentally loosen the zero position after mounting, the stopper element becomes 13 through a lid 15 closed, which in the wing lobes 3 is glued. This also prevents the entry of water.

The subsequent disassembly of the hinge 1 done by unscrewing the tape axis 4 , For this purpose is their head 11 provided with a not visible in the drawing hexagon. By tightening the Schaubverbindung can also be the bias of the spring 8th adjusted and thus the holding force in the zero position are matched to the sash weight.

The 5 shows a mounting situation from above, in which the hinge according to the invention 1 a glassy wing 16 opposite a still, glassy wall 17 pivotally leads. The wing 16 can be tilted 90 ° to the left or right, achieving the stable position c. At a swivel angle Φ <90 °, the wing gets 16 in an unstable position, in which he falls back to the stable zero position o. In this, the angle between hinge tabs and wall tabs is 180 °. A flexible sealing strip 18 covers the inside of the hinge. The ribbon axis 4 remains during the opening game with respect to the pivot plane (drawing plane of 5 and 6 ) fixed, it moves only axially and compressed over its maximum stroke of 5 mm, the spring 8th ,

In 6 is the zero position o of the hinge 1 set to 135 °. An unstable pendulum position b is reached at about 75 °, a stable position c at 90 °.
