The swivel or pivoting portion of BACKGROUND OF THE INVENTION The invention relates to a hinge assembly used for butt-closing door leaves. More particularly, the hinge assembly is used on a furniture frame for cabinet walls and the like with the hinge axis thereof being visible.
Various embodiments of hinge frame assemblies for butt-closing door leaves are known. These prior art hinge frame assemblies permit the door leaf to open only through 90. In many cases, such a small swivel or pivot angle for the door leaf is unsuitable. Further, there is also the risk that the door leaf be over-swiveled by force so that the hinged frame and/or the wood of the door leaf can be over-strained and damaged.
Hinge frame assemblies which may be opened through more than 90, in particular up to 180, generally involve a complicated hinge connection. Such a hinge frame assembly is relatively expensive. Furthermore, such hinge frames having prior art hinge connections are susceptible to difficulties particularly where heavy door leaves are to be hingedly connected to a frame member.
PURPOSE OF THE INVENTION A primary object of this invention is to provide a hinge assembly for butt-closing door leaves that may be opened through I80.
Another object of this invention is to provide a hinge assembly for butt-closing doors having a visible hinge axis and may be adapted to various constructional systems of furniture having different wall thicknesses.
A further object of this invention is to provide a hinge assembly that has a very simple construction. is robust and can be highly stressed and further permits a good and firm seat on the furniture parts.
Another object of this invention is to provide a hinge assembly having a minimum number of parts which require changing to adapt the assembly to various types of furniture and thus only a small inventory of parts is required.
A still further object of this invention is to provide a hinge assembly wherein it is necessary to interchange only parts thereof without having to change the entire assembly when adapting it to various dimensions.
Another object of this invention is to provide a hinge assembly wherein the door leaf to which the assembly is attached may be easily removed without the necessity of disconnecting the fixture parts of the hinge from the door leaf and at the same time provide the capability of a stepless lateral and depth adjustment of the door leaf with respect to the frame member to which it is attached.
SUMMARY OF THE INVENTION The hinge assembly of this invention includes fixture or fastening elements for the frame and the leaf that is hingedly connected to the frame. An independent articulation mechanism has connecting parts which engage each of the fastening elements and are releasably secured or dctachably lockable thereto.
More particularly. the articulation mechanism includes a stationary connecting member and a swivel or pivoting connecting member. The stationary connecting member or fixed portion is visibly attached to the frame fixture element and the swivel or pivoting conthe articulated mechanism may include a single connecting element or a combination of two connecting elements where there are two door leaves connected to the same frame member. The articulated mechanism includes a visible hinge axis on which the swivel portion of the mechanism pivots.
In a specific embodiment of this invention, the fixture or fastening elements connected to the frame and the door leaf have closed pocket type recesses and the connecting portions of the articulated mechanism have projections which are lug-shaped. The lug members are insertable into the pocket-shaped recesses. A screw connection is used to releasably lock the lug member into the pocket type recesses of the fixture elements.
A further specific embodiment of the invention provides an annular capping screw constituting the desired screw connection thereby permitting a clamping of the connecting part of the articulated mechanism at any desired position.
Another feature of the invention is directed to the use ofa fixture flange having screw holes located on the fastening element for the frame member. This fixing element has a casing-shaped plate with the fixture flange located on the free front side thereof. The distance between the screw holes in the flange is the same distance as provided between the holes on the frame member. That is, the screw holes of the flange member are registerable with the holes provided in the frame. When a frame member has a different series of holes with different distances between them. only this fastening element need be changed for use with the other hinge elements.
Another feature of the invention is to provide a pro jecting member such as a thorn or the like located on the stationary connecting element and engaging a bore located on the front side of the frame member. As a result of such a configuration. a considerable additional securing of the position of the hinge assembly on the frame is achieved.
According to another feature of this invention, a swivel part or element of the articulated mechanism includes a lug projection and an eye section that swivels about a pivotal axis. In a specific embodiment, the lug section is offset in axial direction with respect to the eye portion thereby offering the possibility for one and the same door leaf fixture element to be engaged either with a swivel element for a single hinge or a twin hinge arrangement. In a twin hinge arrangement, two swivel hinge parts engage the same fork-shaped stationary connecting element that is attached to the frame fixture so that two door leaves may be hinge connected with one and the same frame fixture element. At the same time, it is also possible to use the same hinge elements for right hand and left hand abutment. That is, the eye portion of the swivel connecting element is so constructed with a corresponding interruption or recess to receive the other swivel connecting part connected to a second door leaf on the same frame fastening element.

DESCRIPTION OF SPECIFIC EMBODIMENTS The hinge assembly, generally designated 1, as shown in FIG. 14, consists of a frame fixture element 2, a leaf fixture element 3 and an articulation mechanism 4 as an independent element. Frame fixture element 2 has a case-like body 5 with a flange 6 in which fixture holes 7 are provided. A recess 8 and an oblong hole 9 are located in the case-like body.
The leaf fixture element 3 as shown in FIGS. 5 through 7 includes a case-like body 10 and a fixing plate 11 including holes 12 for the fastening screws. Casing 10 has a closed recess 13 to which belongs an oblong hole 14. An open recess 15 is located in the leaf fixture element 3 and engages the articulation mechanism 4 if the leaf or door member is closed. The closed recess 13 is offset with respect to the longitudinal axis of the leaf fixture part 3 in a direction parallel to the hinge pivoting axis. Consequently, the leaf fixture element 3 may be used for right hand and left hand abutment and for the twin arrangement as disclosed hereinbelow.
As shown in FIGS. 8-10, the articulation mechanism 4 comprises a forked portion 16 and a swivel part 17 pivotally joined at the hinge bolt or pivot pin 18. Lug members I9 and are designed as connecting pieces and form a part of the fork part 16 and swivel part I7, respectively.
The connecting lug 19 is insertable into the closed recess 8 of the frame fixture element 2. The connecting lug 20 is insertable into the closed recess 13 of the leaf fixture element 3. Threaded holes 21 and 22 located in lugs I9 and 20, respectively. receive fixture screws which lock the lugs 19 and 20 in position within the recesses 8 and 13, respectively. The fastening screws are guided in the oblong holes 9 and 14. In this embodiment, the fastening screws are commonly known as annular tapping screws, i.e., screw bolts with an annular blade at the free front which may sink into the underside of the recess.
A thorn element 23 is disposed on the forked part 16 below the connecting lug l9. Thorn 23 engages a bored hole at the front side of the frame portion so that the position of the articulation mechanism 4 is additionally secured. The connecting lug 20 is offset in the direction of the longitudinal axis of eye 24 as shown in FIG. 10. The offset position of lug 20 corresponds to the position of the closed recess 13 in the leaf fixture part 3 into which recess the lug 20 is inserted.
Another embodiment of a swivel part I7a is shown in FIGS. 11 through 13. Swivel portion 17a includes a fork-shaped eye 24a and is used with a twin hinge made in accordance with this invention. A central clearing 25 is located in the fork-shaped eye 24 as shown. The connecting lug 20a is designed to engage a leaf fixture element with an offset recess. Due to the offsetting of recess 13 with lug 20 with a smaller breadth of the latter, the leaf fixture element 3 may be used not only for a single hinge but also for a twin hinge.
The assembled hinge 1 shown in FIG. 14 is fixed to the frame 26 and the leaf or door member 27. The series of holes 28 in the frame receive holders for shelf bottoms and the like. The bores 7 of frame fixture element 2 are adapted to register with the holes 28 located in the frame 26. In another furniture system having a different hole series, only the frame fixture part need to be interchanged. The hinge elements 3 and 4 need not be changed. If the difference of the hole distances in the series of holes 28 is not very large, an oblong hole 7a may be used for placement of the fastening screw 29.
Connecting lugs 19 and 20 of the hinge assembly shown in FIGS. 14 and 15 displaceably engage the recesses 8 and 13, respectively. A lateral and depth adjustment is thereby ensured at any time for the leaf or door member 27. The thorn 23 located on fork member 16 extends into the edge of the frame 26 and ensures a solid seating of the hinge l. The depth of engagement of lugs 19 and 20 in their respective recesses 8 and 13 may be selected and secured by the annular tapping screws 30 and 31, respectively. The securing of lugs 19 and 20 within their respective recesses or closed guidances 8 and 13, provide a bilateral, very stable connection between the articulation mechanism 4 and the fixture elements 2 and 3. The leaf or door member 27 may be freely pivoted through as shown in FIG. 15.
The forked portion 16 of the articulation mechanism 4 is of such a design that the hinge axis 18 is far advanced from the end of the frame member 26. With other thicknesses of the leaf or door member 27, only the forked portion 16 must be changed. All the other elements of the hinge may be retained.
A twin hinge configuration is shown in the embodiment of FIGS. 16 and 17. Two leaves 27a and 27b are hingedly connected to the frame 26a. The relationship of hinge member I6 to the fixture element 2 remains the same as in the embodiment of FIG. 14. However, in this instance, a swivel part 17a is attached to each of the leaves or door members 270 and 27h. Both of these swivel members are mounted on the pivot 18 and intermesh as shown in FIG. 16. The lugs 200 are firmly disposed within the recesses 13 of the fastening members 3 mounted on the door leaves 27a and 27b.
The elements of the hinges made in accordance with this invention may consist of any suitable material. In these embodiments. the elements are formed of zinc die cast metal having a high resistance.
