Abstract

The adjustable hinge includes an adjusting screw (1) in the form of a threaded pin for adjusting the mutual spacing between hinge arm (14) and setting plate (11). The threaded pin has at one end a device for detachably coupling with a tool and at the other end a plate of larger diameter so that the underneath surface of this plate rests on the base plate (8) to which the hinge arm is connected whilst the edge of the oblong hole in the setting plate rests on the top surface of said plate .

Description

The invention relates to an adjustable hinge according to the preamble of independent claim.

Such adjustable hinges are used to connect two furniture parts with each other, with the adjustable hinge with a furniture hinge on one Furniture part (eg door) and with a base plate on the other furniture part (eg. Body) is attached. Between furniture hinge and base plate are on the one hand a spring mechanism for folding and unfolding the on the furniture band fixed furniture part. On the other hand is on the other side of the spring mechanism attached a hinge arm, which via a parking plate with the base plate is connected, which base plate is now connected to the second furniture part.

The intermediate piece is on the one hand via a locking screw with the hinge arm releasably connected and on the other hand via a so-called side adjustment screw, with which the distance between the hinge arm and the intermediate piece can be adjusted. Along with adjusting this distance between the hinge arm and the intermediate piece then goes the lateral displacement of the Furniture hinge approximately perpendicular to the rest of the hinge, and that is the first furniture part (eg door) approximately perpendicular to the second furniture part (eg carcass) emotional. Thus, the door can then be moved laterally in the width of the cabinet be that the vertical side walls of the cabinet then aligned with the door.

DE 2660736 C2 shows an adjustable hinge according to the above-mentioned Genus with intermediate piece, in which a locking screw and a Adjusting screw are screwed. The locking screw now passes through the Hinge arm and is screwed down down to the base plate. The adjusting screw is with its annular groove below the screw head in a self-contained slot inserted in the hinge arm and can thus turning the intermediate piece approximately in the direction of Screw symmetry line relative to Move hinge arm. The intermediate piece engages with legs in horizontal grooves of the base plate.

Disadvantage of this embodiment is that between the annular groove of the Adjusting screw and the hinge arm and between the intermediate piece and the Grooves of the base plate a relatively large game prevails and thus an exact Adjustment is not possible. Due to the fact that the adjusting screw has a large Has screw head, a relatively large height is given. In addition, the Assembly complicated, since the adjusting screw first in the designated Bore in the hinge arm must be introduced, then a piece in the Screwed thread in the spacer and then in the slot part of the Hinge arm must be moved. In addition, a low robustness of this Connection given because the adjusting screw only in an unreinforced Long hole of the additional larger diameter hole in the hinge arm rests, which hinge arm under the action of elastic or plastic can deform. The additional hole larger diameter in the slot has a larger diameter than the head of the adjusting screw. This will turn a exact adjustment not possible. Also, the strength is due to the Cross-section reduction of the adjusting screw by providing the annular Groove reduced.

The US 5,159,740 also shows an adjustable hinge with locking screw and adjusting screw according to the general category mentioned above. The Locking screw is provided here as in DE 26 60 736 C2, but shows the adjusting screw the functional inversion. The slot is no longer in the Hinge arm provided, but in the intermediate piece, in which slot the engages lower annular groove of the adjusting screw, wherein the adjusting screw in a thread is screwed into the hinge arm. The slot is to the edge of the Intermediate piece formed open. The intermediate piece is over rag and special shaped leaf spring attached to the base plate.

Disadvantage here is again that a big game between the annular groove the adjusting screw and intermediate piece prevails and between the Intermediate piece and the base plate. A relatively low robustness prevails the not additionally reinforced and also to one side open slot. Again, by the cross-sectional reduction of the adjusting screw by the annular groove reduces the strength. In addition, only small adjustment paths therefore only possible because of the tilting of the adjusting screw in the slot then another adjustment between the hinge arm and the intermediate piece is no longer possible because the adjusting screw wedged there.

WO 97/22773 shows a similar embodiment as the US 5,159,740 with the same disadvantages. Here, however, is an adjustment also approximately in the longitudinal axis from intermediate piece and hinge arm to a complicated mechanism with Spiral screw, rack and rocker arm possible. Due to the multitude of these Components creates an additional game, which in turn is disadvantageous to the exact adjustability and robustness. The slot is here again open at the edge.

US 4,176,422 (or also DE-2819100) discloses a very similar Furniture hinge as the WO 97/22773, but without further adjustment in Longitudinal axis of intermediate piece and hinge arm. Here is the adjusting screw for adjusting the mutual distance between the hinge plate and Base plate in turn formed as a threaded pin with an annular radial Puncture of smaller diameter between the threaded part and the plate of the Adjusting screw. This radial recess of the adjusting screw again engages in a at the edge open slot, in which the adjusting screw from the edge must be threaded.

EP-0821125A1 already discloses a furniture hinge with a in itself closed slot of a lower plate between the base plate and the hinge arm, However, this slot is not for an adjusting screw for adjusting the Distance between base plate and hinge arm provided, but for a Locking screw. The slot has an additional hole larger Diameter than the slot on.

The plates of the adjusting screws of the prior art all have the same or a smaller outer diameter than the threaded portion of Adjusting screws and further a radial puncture smaller diameter between plate and thread. The adjusting screws are either in a On the edge open slot is threaded on the edge or by an additional Bore in self-contained slot, which additional hole a larger diameter than the diameter of the plate and / or the Thread of the adjusting screw.

The object of the invention is now, an adjustable hinge of the above Type of adjustment of the distance between hinge arm and base plate or Intermediate piece and thus between two (furniture) components in such a way, that setting of this lateral distance simple, accurate, reproducible and without damage to the hinge can be performed at the same time simple, easy and inexpensive construction of the hinge.

As a solution to the aforementioned object, the technical teaching of independent claim 1 is used.
An essential feature here is that the plate of the adjusting screw has a larger diameter than the thread of the adjusting screw and that the slot is formed as a breakthrough by the control plate in itself. The prerequisite is that the adjusting screw is a threaded pin having at one end a device for releasable coupling with a tool and at the other end a plate, wherein the underside surface of the plate rests on installation in the adjustable hinge on the base plate and on the top surface of the plate the edge of the oblong hole of the adjusting plate.

The advantage here is that virtually no play between the hinge arm and the setting plate and there is only a slight clearance between the setting plate and the base plate, making the setting easy, accurate and reproducible.

This also ensures easy assembly / disassembly of the adjusting screw, because no threading an annular groove of the adjusting screw in the slot, about over additional holes in the hinge arm, are needed.

Another advantage is a simple, lightweight and inexpensive construction of the Hinge while maintaining high mechanical stability, so that a Damage to the hinge during the adjustment significantly reduced becomes.

In a preferred embodiment of the invention it is provided that the spherical or underside surface and / or top surface of the dish are formed conically.

This offers the advantage that, regardless of the adjustment, the bearing surface between the plate of the adjusting screw and the adjusting plate always approximately constant is large and thus the durability is increased and also an exact, easy and reproducible adjustment is ensured.

It is further preferred if in the area of the support of the plate on the Base plate this bearing surface also spherical or conical, suitable for Plate shape, is formed. As a result, the support surface is increased and the Plate stabilized on the base plate.

The advantage here is that the game over the entire adjustment is almost constant, which in turn leads to a simple, exact and reproducible adjustment process leads. Also, a tilting and thus wedging the adjusting screw in the slot is excluded because the annular groove as in the prior art completely missing, and therefore large adjustment paths can be passed.

The slot is always formed closed in the control plate, ie as in closed breakthrough through the material of the actuator plate and not as open notch, which runs open towards the edge of the shelf. This brings additional advantages in terms of the strength of the actuator plate and thus the entire hinge. The control plate with closed slot is only due the newly developed adjusting screw possible, since this no radial puncture has more, by means of which they threaded in an open notch in the shelf and is held, but this adjustment screw can now easily from below be introduced into the closed slot and in the hinge arm be screwed on and then lies on the base plate with his plate.

In addition, on the edge of the oblong hole in the control plate form embossing, ripples and / or deflections in the direction of plate as additional stiffening of the Langlochrandes be provided.

This can be achieved that the construction cost and with only Low weight is carried out because only small plate thicknesses then for a sufficient strength suffice.

In the following the invention is based on only one embodiment explaining illustrative drawings. Here are the drawings and its description further features and advantages of the invention.

a perspective view of an adjusting screw of the adjustable hinge.

FIG. 1 is a perspective view of an embodiment of a device according to the invention adjustable hinge shown in the assembled state, with the door 15 with the body 9 is connected via the adjustable hinge.

Here is the furniture band 2 of the adjustable hinge on appropriate Attached fasteners on the door 15 and the base plate 8 via also corresponding connecting elements in the plate 16 with the body. 9 connected, wherein the plate 16 is preferably integrally connected to the base plate 8 is.

On the furniture band 2, a spring-folding mechanism 20 is now attached, which is the To open the door 15 to allow about 90 ° with respect to the body 9. This spring-folding mechanism 20 here consists of two angular arms, which are each mounted on the furniture band 2 via two axes and over two more axes on the hinge arm 14. The spring load happens here in that around one of the axes around, preferably one of the axes on Hinge arm 14, now a leg torsion spring is attached, which is to one on one of the angled arms and the other on the hinge arm 14th

The hinge arm 14 itself is now a locking screw 17 with the control plate 11 connected, this locking screw 17 via a corresponding slot in the form of a closed opening through the hinge arm 14 passed through and into a corresponding threaded hole in the adjusting plate 11th is screwed. By this locking screw can on the one hand a relative Adjustment of the hinge arm 14 to the adjusting plate 11 in the longitudinal direction and On the other hand, these two parts can be firmly bolted together. to better support these two parts with each other, it is provided that the Hinge arm 14 at its the actuating plate 11 side facing a corresponding Corrugation has, which then in a matching ribbing on the top the adjusting plate 11 interlocking engages.

The adjusting plate 11 is U-shaped, wherein at the U-legs in the 90 ° angle In addition, further approaches are appropriate and the control plate 11 approximately in the direction the symmetry axis of the locking screw 17 is resilient and with nose-shaped hook is provided so that this adjusting plate 11 on simple and on Known manner can be releasably clipped onto the base plate 8. For this purpose, no tool is needed, so that a very fast and easy assembly can be done.

The base plate 8 itself is then via corresponding connecting elements with the Carcass 9 connected, with an additional plate 16 on the base plate. 8 may be provided, through which the connecting elements pass.

FIG. 2 now shows an enlarged view of the region of the adjusting screw 1, according to FIG. 1.

Here it can be seen that the slot 10 as a closed breakthrough by the Stellplatte 11 is formed and in its peripheral region downwards is deformed and thus contact surfaces 12 are created, which on the Top 6 of the plate 5 of the adjusting screw 1 suitably rest.

It is possible that both longitudinal sides of the elongated hole 10 of the control plate 11th with the contact surfaces 12a and 12b on the upper side 6 of the plate 5 of the Adjustment screw 1 rest or only one side with the contact surface 12a or 12b, depending on the tolerance position of concentricity and nut thread position. advantage Here is that manufacturing tolerances in the concentricity and nuts-threaded position on the Split sides and thus only half of the tolerances act.

Furthermore, it can be seen in Figure 2 that both the top 6 and the bottom 7 of the plate 5 of the adjusting screw 1 are in a curved shape, wherein the bottom 7 then on a corresponding, also curved, shaped Support surface 19 of the base plate 8 rest fully. This should be a big and constant contact surface between the bottom 7 of the plate 5 of the adjusting screw. 1 and the bearing surface 19 of the base plate 8 are produced.

Furthermore, it can be seen in Figure 2, that a highest stability of the construction is achieved in that the power flows 4 through as few parts over As short as possible distances with the least possible force deflections. As a result, an overuse of weakly dimensioned parts avoided and thus a corresponding durability and reproducibility the lateral adjustment of the adjustable hinge ensures.

When pressure is applied in the direction of 4a now presses the side adjustment screw 1 on the Base plate 8 on the body 9 in a straight line, without deflection.

When tensile load in the direction 4b of the power flow takes place in the cross-sectional plane through the middle of the side adjustment screw 1, d. H. on the shortest path from the Base plate 8 on the hinge arm 14th

FIGS. 3 a to 3 c each show a section through the longitudinal axis of the adjustable hinge in the assembled state, according to FIG 1, wherein in Figure 3a an already set state between the door 15 and the body. 9 is shown; in Figure 3b, the adjusting screw 1 is in the fully rotated state represented and in Figure 3c, the adjusting screw 1 in fully rotated state.

The adjustment 3 can therefore by a screwing or unscrewing the adjusting screw 1 are set in the threaded bore of the hinge arm 14, wherein the relative distance of the hinge arm 14 to the adjustment plate 11 and the base plate. 8 is then deflected directly over the spring-folding mechanism 20 and the furniture band. 2 in the door 15 and thus in the figures 3a to 3c, the door from bottom to top or reversed can be moved.

By screwing and unscrewing the adjusting screw 1 so the door is 15th moved laterally to the body 9, and thereby a lateral adjustment is achieved. This adjustment can be done with firmly screwed locking screw 17, so that the Hinge arm 14 and the adjusting plate 11 at the location of the locking screw 17th are not movable to each other. This locking is done by complete Screwing the locking screw 17 on the base plate 8, where they then arresting fixed.

In Figure 3b, the door 15 is adjusted slightly too high, with respect to the body 9, and in 3c, the door 15 is adjusted slightly too low compared to the body. 9

It can also be seen from FIGS. 3 a to 3 c that, depending on the adjustment path, the Adjustment screw 1 now their axial position with respect to the base plate 8 and the adjusting plate 11 changes, which is due to the fact that the distance between Hinge arm 14 and adjusting plate 11 and base plate 8 is changed. Exactly taken the angle between the hinge arm 14 and the adjusting plate 11 changes Base plate 8, since these three aforementioned parts in the field of Locking screw 17 fixed firmly and unverrutschbar to each other.

Compared to Figure 3a, the adjusting screw 1 in Figure 3b so slightly to the right tilted and the adjusting screw, according to the figure 3c, in comparison to Figure 3a tilted slightly to the left, but the bearing surface of the bottom 7 of the Tellers 5 of the adjusting screw 1 each remain constant, due to their curved shape and due to the curved shape of the support surface 19 of the Base plate 8.

In Figure 4 is now finally a perspective view of a Adjusting screw 1 shown, which can be seen here that the Adjusting screw is designed in principle as a threaded pin and this Adjustment screw 1 at the top of a device 18 in the form of a Phillips for releasably receiving a tool has attached and on lower, free end of a screw 5 larger diameter.

Also, this Figure 4 it can be seen that the top 6 and bottom 7 of the Screw plate 5 are curved, for example, ball or conical or in any other free form surface. This area then corresponds to the support surface 19 of the base plate 8, the course formed as equal as the shape of the bottom 7 of the plate. 5

The diameter of this plate 5 corresponds approximately to twice the Thread diameter 13 of the adjusting screw 1, and the height of the plate. 5 corresponds to about one-fifth of the total length of the adjusting screw 1. This Dimensions are merely preferred dimensions and may be embodied in one embodiment deviate from these dimensions.
