HINGE ARM MOUNTING

Abstract: A hinge arm mounting comprises a match member (1) for engaging a hinge arm and creating a disassembling connection with the latter and a fastening member (2) for mating the match member (1) with their position in relation to each other being adjustable in a direction transversely to a main axis (A-A) of the hinge arm so that the latter is indirectly fastened to a furniture wall member. The fastening member (2) is placed crosswise to and onto the match member (1), the former being superimposed on the latter merely in a middle section of the length of the match member (1). An eccentric disk member (3) for adjusting the position of the match member (1) in relation to the fastening member (2) in a direction transversely to the main axis (A-A) of the hinge arm is arranged practically in a point of intersection of these two members (1, 2). In their cross sections, the match member (1) is U-shaped and the fastening member (2) is OMEGA -shaped. In order to guide the match member (1) against the fastening member (2) when adjusting the position of the match member (1) in relation to the fastening member (2) in a direction transversely to the main axis (A-A) of the hinge arm, the match member (1) provides an abutment (16) engaged by a free edge (25) of a top plate (24) of the fastening member (2), and a slot (18) engaged by an overhang (27) of the top plate (24) of the fastening member (2).

Description: HINGE ARM MOUNTING The invention relates to a hinge arm mounting comprising a match member for engaging a hinge arm and creating a disassembling connection with the latter and a fastening member for mating said match member, with their position in relation to each other being adjustable in a direction transversely to the main axis of the hinge arm so that the hinge arm is indirectly fastened to a furniture wall member. A hinge arm mounting of the kind set forth above is known from Huber's EP 0790378 (Grundplatte jiλr ein Scharnier). Basically, the match member - a plate-type component (Verankerungsplatte) - is a cross-shaped member. A section thereof adapted to mate the hinge arm constitutes a buckling part that partly projects out from said 'plate', and another section thereof - a section arranged crosswise to said buckling part - provides two platelike wings. The fastening member (Befestigungs- platte), too, is basically a platelike component composed of two plate sections, either one being arranged on one side of said match member buckling part and connected to each other within a tunnel area existing below said match member buckling part. Either fastening member plate section provides a supporting rim along its three free sides foreseen to meet the surface area of a furniture wall member, said fastening member plate section and the supporting rim thereof as well as the furniture wall member defining a flat chamber for receiving one of said two platelike match member wings. One of said two match member wings provides a hole - a bearing - for engaging a pivot section of an eccentric disk member arranged in an oblong hole foreseen in the respective superimposed fastening member plate section in order to adjust the position of said match member and fastening member in relation to each other transversely to the main axis of the hinge arm. Said eccentric disk member further provides a rotary head for engaging a screw driver, the outer diameter of said rotary head exceeding the nominal width of said oblong hole. In said hinge arm mounting - in its assembled state - said pivot section of said eccentric disk member protrudes beyond a lower level of said match member wing and constitutes a rivet head obtained by a mechanical treatment of said pivot section. In order to provide a compartment for accommodating said rivet head, the respective match member wing, too, has a rim element. Between said rotary head on the one hand and rivet head on the other hand said eccentric disk member holds said match member wing and fastening member plate section in a locked manner. Also foreseen is an analogous locked holding of another pair of match member wing and fastening member plate section, which holding permits a displacement of the respective components in relation to each other transversely to the main axis of the hinge arm. To this end, the respective match member wing provides an oblong hole arranged transversely to the main axis of the hinge arm, said hole being engaged by a hollow pin made by a local shallow drawing of sheet metal of the fastening member plate section, the free end part of said hollow pin being flanged (like a tubular rivet) below the match member wing. Said prior art hinge arm mounting of prior art has numerous drawbacks: a general disadvantage is that the hinge arm mounting as a system is not symmetrical, namely the two fastening member plate sections as well as the two locked assemblies of two pairs comprising a fastening member plate section and a match member wing are mutually different; since the rotary head of the eccentric disk member resides in a corner area of one of the two fastening member plate sections, the approach of a screw driver is rendered difficult in at least one half of installed hinges; the match member, when installed, rests practically entirely on the surface of the respective furniture wall member, and each fastening member plate section rests, again practically in its entirety, on the respective match member wing, which results in large surfaces generating (not much desired) friction, and not excluded are cantings causing difficulties when adjusting the hinge arm by using the eccentric disk member; since the match member wing provides a rim element, the supporting rims of the fastening member plate sections must be correspondingly higher; by the use of riveting (the pivot section on one side of the hinge arm and the hollow pin on the other side of the hinge arm) for obtaining a disassembling connection of the fastening member and match member, the uniformity of the articles us not guaranteed; the mutual binding of the fastening member plate sections (to create a composite fastening member) is a very demanding technological step because it occurs inside the match member; there exists a possibility that the binding of the fastening member plate sections becomes a link, which means that the required stability of the assembly is not guaranteed. It is an object of this invention to obviate the disadvantages of the prior art hinge arm mounting while preserving the possibility of continuously shifting the match member in relation to the fastening member of a hinge arm mounting. Proceeding from a hinge arm mounting as defined above in the introduction, the object of the invention is achieved by placing a fastening member crosswise to and onto a match member so that the former is superimposed on the latter merely in a longitudinal middle section of said match member, and arranging an eccentric disk member (for adjusting the position of the match member in relation to the fastening member in a direction transversely to the main axis of the hinge arm) practically in the point of intersection of these two members. It is a result of such an approach that no doubling of the material components under the fastening screws occurs, the thickness of the material components under the fastening screws is reduced, no working step of combining certain fastening member sections for making a composite fastening member is necessary, and a hinge arm mounting for a hinge is obtained where a screw driver can approach the eccentric disk member irrespective of the specific location of the hinge inside a furniture box. Actually, the match member is U-shaped and the fastening member is Ω-shaped in their respective cross-sections. No holes (openings, recesses) exist in the leg sections of either the fastening member or the match member, which essentially contributes to the stability of the hinge arm mounting. In order to guide the match member against the fastening member when adjusting the position of the match member in relation to the fastening member in a direction transversely to said main axis of the hinge arm, the match member provides an abutment engaged by a free edge of a top plate of the fastening member, and a slot engaged by an overhang of said top plate of the fastening member. Since said eccentric disk member resides essentially in the middle between said abutment and slot of the match member, the mutual guiding of the two mating members is actually a "narrow-gauge" guiding which excludes any canting. Finally, in order to adjust the position of the match member in relation to the fastening member in a direction transversely to the hinge arm, said eccentric disk member provides a rotary head arranged over said top plate of the fastening member, a pivot section coaxial with said rotary head and arranged in a round-section bearing hole of said top plate of the fastening member, a disk eccentrically connected to said pivot section, the diameter of said disk being equal to the nominal width of an oblong hole of the match member, said oblong hole engaging said disk, and a terminal disk connected to said eccentrically mounted disk and arranged immediately below the inner surface of a top plate of said longitudinal middle section of match member. An arrangement of the kind set forth above guarantees the provision of an installing length between said rotary head and the terminal disk of said eccentric disk member, whereat said installing length can be defined and repeated so that the intensity of the mating of the fastening member and of the match member can be determined in advance. The invention is described in the continuation with reference to the enclosed drawing showing an embodiment of the invention in more detail, the scope of protection, however, is not limited to this embodiment. In the drawing: Fig. 1 is an elevational view of a longitudinal section of a hinge arm mounting taken along a middle line (line I-I of Fig. 2), Fig.2 is a top view of the hinge arm mounting of Fig. 1, Fig.3 is a three-dimensional elevation of a fastening member of the hinge arm mounting, and Fig. 4 is a three-dimensional elevation of a match member of the hinge arm mounting. A cursory comparison of two embodiments is sufficient for realizing that the suggested hinge arm mounting essentially differs from the one of EP 0790378. The match member (a traverse member in the prior art) is here a linear member, more precisely a U-profile member (Fig. 4), and the fastening member (a composite, essentially flat two-part fastening member in the prior art) is here a one-piece Ω-profile member (Fig. 3). According to the invention, a 'traverse' assembly is a result of assembling a match member 1 and a fastening member 2. It is an essential feature of the invention that an eccentric disk member 3 is arranged essentially in the point of intersection of the match member 1 and the fastening member 2, i.e. close to the elements constituting a form-closed connection of the fastening member and the match member on the one hand, and of a hinge arm and the hinge arm mounting on the other hand. In fact, the hinge arm mounting according to the invention is not a 'plate' assembly (Platte in prior art), but a cross-shaped assembly. The hinge arm mounting according to the invention is composed of the match member 1, the fastening member 2 traversing it, and the eccentric disk member 3. In an assembled state of the hinge arm mounting, the eccentric disk member 3 conveniently connects said two members 1, 2 to a locked assembly with a single degree of freedom, i.e. with the possibility of the match member 1 to be shifted with respect to the fastening member 2 in parallel with said main axis A-A (Fig. 2) of the hinge arm mounting, said main axis corresponding to the main axis of the hinge arm (not shown). Basically, the match member 1 is a U-shaped profile, which is, in the assembled state of the hinge arm mounting, by the free edges of its leg sections 11 oriented against a furniture wall member. According to the invention, the leg sections 11 conveniently comprise no openings or recesses that would affect their stability. The configuration of a top plate 12 of the match member 1 comprises three distinctive longitudinal sections, namely a first - proximal - longitudinal section 13 close to a hinge swivel axis and adapted to engage a first adapter piece of the hinge arm, a second - middle - longitudinal section 14 adapted to be suspended on the fastening member 2 and to operate the eccentric disk member 3 as well as to engage two stabilizing prongs of the hinge arm, and a third - distal - longitudinal section 15 adapted to engage a second - spring-loaded - adapter piece of the hinge arm of a quick-assembling hinge. The configuration of said first (13) and third (15) longitudinal sections depends on the configuration of the hinge arm (no objective of this invention). When mounting the hinge arm onto the respective hinge arm mounting, a first step relates to inserting said first (stationary) hinge arm adapter piece into a bearing box A (Fig. 1) foreseen close to said hinge swivel axis, then the distal end of the hinge arm is swung against the hinge arm mounting with the stabilizing prongs of hinge arm entering recesses C (Fig. 2) through openings D (Fig. 3), and, finally, said distal spring-loaded hinge arm adapter piece enters a recess B (Fig. 1) and snaps below a cross-bar E. The configuration of the match member middle section i.e. the second longitudinal section 14 comprises three elements essential for creating the hinge arm mounting, namely an abutment 16 engaged by a free edge 25 of the fastening member 2, a longitudinally arranged oblong hole 17 engaged by a disk 33 (Fig. 1), and a transverse slot 18 engaged by an overhang 27 of the fastening member 2. The fastening member 2 shaped as an Ω-profile comprises, in a single piece, two flat mounting pieces 21 providing (in this example) two sunk holes 22 for screws (not excluded are other embodiments of fastening taken from prior art) for fastening the hinge arm mounting onto a respective furniture wall member, two leg sections 23 bound thereto and again without any holes or recesses, and a top plate 24 connecting them. Three elements of the top plate 24 of fastening member 2 are important for the hinge arm mounting, namely the free edge 25 for engaging and slidingly guiding the fastening member 2 in relation to the match member abutment 16 when adjusting the position of the match member 1 in relation to the fastening member 2, a round-section bearing hole 26 co-operating with a pivot section of the eccentric disk member 3, and the overhang 27 bent perpendicularly to the top plate 24 of the fastening member and inserted into the match member transverse slot 18 as well as slidingly guided therein when adjusting the position. The outer height of the match member leg sections 11 observed at the middle longitudinal section 14 of the match member 1 is a little smaller than the height dimension of a tunnel existing below the top plate 24 of the fastening member 2 (see Fig.l) so that, when adjusting the hinge arm, the match member 1 practically does not slide on the surface of the furniture wall member. The eccentric disk member 3 comprises, conveniently in a single piece, a rotary head 31 (providing a groove for the screw driver) residing over the top plate 24 of the fastening member, a pivot section 32 coaxial with it and residing in the bearing hole 26 of the top plate 24 of the fastening member, a disk 33 connected to it and providing a diameter equal to the clearance of the oblong match member hole 17 in which it resides, and a terminal disk 34 connected to the eccentrically mounted disk 33 and arranged immediately below the inner surface of the top plate of the middle section 14 of the match member. Thus, in a clearance between the rotary head 31 on the one hand and the terminal disk 34 on the other hand, the eccentric disk member 3 retains the fastening member 2 and the match member 1 in a locked assembly permitting mutual movement.
