Alternatively, the inventive door hinge is provided for a hidden placement between a door leaf and door frame, wherein the hinge parts can be inserted into recesses provided in the door frame and in the narrow edge of the door leaf and are which connected to each other by means of two hinge brackets that can rotate relative to each other.
EP 1 308 592 A2 discloses a door hinge having two hinge parts that are connected in articulating fashion, with one of the hinge parts having a base plate for attachment to a door frame or door leaf and at least one insert that is adjustable in two directions relative to the base plate. The two hinge parts each have a base plate, which, above and below the two hinge brackets that are connected to each other in articulating fashion, has two inserts that are adjustable relative to the base plate. The hinge brackets are secured to the inserts, with each of the inserts accommodating one of the hinge brackets in rotary fashion and the other of the hinge brackets in a manner that allows it to rotate and slide along a sliding guide.
On one of the hinge parts, the inserts are adjustable in the vertical direction relative to the base plate. A groove guide extending in the vertical direction is provided along with adjusting cams that act on the inserts and are supported on the base plate. On the other hinge part, an adjustment is provided in two directions that are perpendicular to each other, permitting an adjustment parallel to the front side of the hinge parts by means of oblong holes. The corresponding adjustment is used to adjust the position of the closed door leaf perpendicular to the surface of the door leaf. This adjustment is used to adjust the outer surface of the door relative to the matching surface of a door frame, thus also changing the pressure exerted on a door seal.
The corresponding horizontal adjustment is therefore referred to in the trade as the closing pressure adjustment. An adjustment perpendicular to the front side of the corresponding hinge part is enabled by an adjusting screw. This adjustment is used to adjust the gap relative to the frame on both sides when a door leaf is closed. The corresponding adjustment is therefore known in the trade as lateral adjustment.
DE 10 2009 038 955 A1 discloses a door hinge having two hinge parts that are connected in articulating fashion, where one of the hinge parts has a base plate for attachment to a door frame or door leaf and having at least one insert that is adjustable in two directions relative to the base plate. A lateral adjustment is carried out by means of an adjusting screw and a closing pressure adjustment perpendicular thereto is carried out by means of at least one oblong hole. The adjusting screw is situated between a front plate and a back plate. Enabling an additional adjustment in another horizontal direction requires at least one additional clamping or intermediate plate. This known door hinge is comparatively complex in design and requires a large number of parts to be screwed to one another.
The present invention provides a door hinge that overcomes the shortcomings of the known arts.
In an embodiment, a door hinge is provided for a hidden placement between a door leaf and door frame, wherein the hinge parts can be inserted into recesses provided in the door frame and in the narrow edge of the door leaf and are which connected to each other by means of two hinge brackets that can rotate relative to each other.
In another embodiment, a door hinge is provided having two hinge parts that are connected in articulating fashion, in which one of the hinge parts is provided with an adjustment in two directions through simply designed means. That is, one of the hinge parts has a base plate for attachment to a door frame or door leaf and at least one insert that is adjustable in two directions relative to the base plate. An intermediate piece is situated between the insert and the base plate that is movable relative to the base plate in a first direction along a first linear guide. The adjustable insert may be embodied in the form of a recess for a hinge flap. The insert is movable relative to the intermediate piece in a second direction along a second linear guide and in that a fixing means for providing a clamping locking action extends through a front section of the base plate, the intermediate piece, and the insert.
The first and second linear guides provide a precise adjustment in two directions, in particular two directions that are perpendicular to each other, without the base plate being tilted or rotated relative to the insert. The first and second linear guides provide for the adjustment in a simple way on the comparatively small intermediate piece.
In one form, the first and second linear guides may be formed of oblong holes or groove guides. To produce a groove guide, at least one protrusion provided on one of the parts to be guided relative to each other is accommodated in a groove provided in the other part. In one form, an oblong protrusion extends in the direction of the linear guide and in another form, two protrusions are spaced apart from each other in order to prevent a tilting relative to the provided movement direction.
Alternatively, the intermediate piece, in order to form the first linear guide and second linear guide embodied in the form of groove guides, has at least one protrusion that engages in an associated groove in the base plate or the insert. The base plate and the insert can be shaped in a correspondingly simple fashion. The above-described grooves also are easily produced subsequently with a high degree of precision. Since the intermediate piece is only provided to enable the above-described adjustability in two directions, it can be comparatively small and is therefore easy to produce. Apart from the shapes provided for the guidance, a simple plate or disk shape is suitable.
There are thus a variety of possibilities for producing the intermediate piece. The simple shape of the intermediate piece makes it possible to use an injection-molding process. Furthermore, the intermediate piece can be formed as a shaped piece of sheet metal, which merely requires a stamping procedure. The above-described protrusions can then be formed out of the piece of sheet metal in a simple way. It is also conceivable to insert protrusions in the form of pins or the like into bores in the intermediate piece. In such an embodiment, the protrusions also can be composed of a particularly rugged and/or low-friction material.
Since the intermediate piece is situated between the base plate and the insert, the first linear guide on the one hand and the second linear guide on the other are suitably situated on opposite sides of the intermediate piece.
When a fixing means is loosened, the base plate can be moved in a controlled fashion relative to the insert, along the two linear guides without tilting. The fixing means can, for example, be a screw that engages in a threaded piece. In that case, tightening the screw causes the threaded piece to pull the insert and the intermediate piece against the base plate in a clamping fashion.
In another embodiment, two hinge brackets that cooperate in articulating fashion are provided as the connection between the hinge parts. The hinge parts each have a base plate and two inserts. Each of the inserts accommodates one of the hinge brackets in rotary fashion and the other of the hinge brackets in a manner that allows it to rotate and slide along a sliding guide of the insert.
Such hinge parts can e provided for a hidden placement between the door leaf and door frame, in recesses provided in the frame and in the narrow edge of the door leaf.
The intermediate piece enables an adjustment in two directions that are preferably perpendicular to each other. In particular, it is possible for the at least one insert to be adjustable relative to the base plate along a vertical direction extending parallel to a pivot axis of the door hinge and perpendicular thereto along a horizontal direction. With regard to the closed position of the door leaf, an adjustment can be carried out in an additional horizontal direction on the other hinge part, thus producing a door hinge that is adjustable in a total of three directions.
In one form, the insert is an injection-molded metal part. This achieves the advantage that the shapes provided to produce the second linear guide are comparatively simple and can be easily produced using a metal injection molding process. Alternatively, a groove can be subsequently produced in an injection-molded metal part. This enables a particularly inexpensive manufacture. In order to minimize overall production costs while simultaneously achieving good stability and function of the door hinge, the base plate can be formed as a one-piece component composed of sheet metal. Here, too, it is easy to produce the shapes required for the first linear guide.
In an embodiment, the door hinge includes two hinge parts that are connected to each other in articulating fashion. One of the hinge parts has a base plate for attachment to a door frame or door leaf and at least one insert that is adjustable in two directions (x, y, z) relative to the base plate. An intermediate piece is situated between the insert and the base plate that is movable relative to the base plate along a first linear guide in a first direction (x). The insert is movable relative to the intermediate piece along a second linear guide in a second direction (z). A fixing means for providing a clamping locking action extends through a front section of the base plate, the intermediate piece and the insert
Further features and advantages of the invention will become apparent from the description of embodiments that follows, with reference to the attached figures, in which:
The following is a detailed description of example embodiments of the invention depicted in the accompanying drawings. The example embodiments are in such detail as to clearly communicate the invention and are designed to make such embodiments obvious to a person of ordinary skill in the art. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention, as defined by the appended claims.
The invention provides a door hinge 1 having two hinge parts 1a, 1b that are connected in articulating fashion. One of the hinge parts 1a has a base plate 2a for attachment to a door frame or door leaf and at least one insert 3a that is adjustable in two directions relative to the base plate 2a.
The precise embodiment of the first hinge part 1a is shown in detail in the exploded view of
The intermediate piece 6 has two protrusions 7 on its top surface. The two protrusion engage in a groove 8 extending along the first horizontal direction x and thus cooperate with the groove 8 to form a groove guide. The groove 8 is hidden from view in
With the two intermediate pieces 6, the two inserts 3a of the first hinge part 1a can be precisely adjusted relative to the base plate 2. The two linear guides prevent the occurrence of tilting.
In order to fix the inserts 3a in the desired, in an adjusted position relative to the base plate 2a on the first hinge part 1a, a fixing means in the form of a screw 11 is provided. The fixing means or screw 11 extends through a front section of the base plate 2a, the intermediate piece 6, and the associated insert 3a and engages in a thread of a threaded piece 12 situated underneath the insert 3a. Tightening the screw 11 causes the threaded piece 12 to pull the insert 3a and the intermediate piece 6 against the base plate 2a in a clamping fashion. In the fixed state, the door hinge is secured against unintended adjustment. Adjustment is re-enabled once the screw 11 is loosened.
As is shown in
