Definitions
- the present invention relates to a hinge junction device, in particular for wardrobe and cabinet doors.
- hinge junction devices for wardrobe and cabinet doors or similar furniture components can each comprise at least two rocking rods hinged on appropriate attachment elements in turn connected to a door or a post.
- rocking rods in addition to supporting the weight of a door, define an appropriate opening and closing trajectory for the door itself, characterized by a non-fixed but varying rotational axis which enables both to make the door abut against the post edges when it is in a closed position and to form a very wide opening angle of the door, even wider than 90°.
- a hinge junction device relying on rocking rods, and therefore defining a mobile hinging axis; in this reference, a first sub-assembly of the hinge junction device is connected to the furniture post and it is composed of two pieces, while a second single-piece sub-assembly (operatively connected to the rocking rods) is directly in connection with the door. Regulating means are then present in the first sub-assembly, in order to allow ah horizontal relative sliding of the two pieces of the same first sub-assembly. It is also known from DE 2353043 another mobile-axis junction device, substantially similar to the one just above cited.
- a second sub-assembly composed by a monolithic block is directly and unremovably engaged to a furniture door, while in the first sub-assembly (directly connected to the fixed part of a furniture component) regulating means allow the two pieces of the same sub-assembly to slide relatively in a vertical direction and to move relatively in a horizontal plane.
- the mentioned attachment elements are directly connected not only to a door or a post, but also to the ends of said rocking rods.
- These attachment elements therefore must have a shape adapted both for anchoring to the door and the post, and for enabling articulation with the rocking rods, and they are made of a material of appropriate workability and mechanical-strength features.
- the technical task underlying the present invention is to provide a hinge junction device capable of substantially overcoming the mentioned limits.
- Another important object of the invention is to provide a device of reduced production costs and adapted to be made with simple and quick manufacturing cycles.
- junction device in accordance with the invention has been generally identified by reference numeral 1.
- It comprise one or preferably two pairs of two rocking rods 2 and 3, made of a steel material for example, adapted to support a door 4 and to define the opening and closing trajectories of door 4 relative to a post 5 of a wardrobe or similar piece of furniture (in the following wardrobe).
- rocking rods 2 and 3 are interposed between a first attachment set 6, connected to door 4 for example (as in the accompanying figures) or also to a post 5, and a second attachment set 7, to be connected to post 5 for example or also to door 4.
- the attachment sets 6 and 7 respectively comprise a first portion 8, defined by a first hinging element, for engagement with respective ends of the rocking rods 2 and 3, and a second portion 9, defined by a second hinging element, for engagement with opposite ends of the rocking rods 2 and 3.
- rocking rods 2 and 3 are defined by levers of reduced vertical overall dimensions (thickness) and are disposed and move in respective parallel, preferably horizontal, lying planes, vertically offset relative to each other. This ensures reduced overall dimensions and eliminates all interference problems during movement.
- the two levers 2 and 3 practically form a four-bar linkage so that the door can move relative to the post according to an instantaneous motion which is rotatory about a (vertical) axis defined by the intersection of the vertical plane containing the straight line passing by the hinging points of the rod or rocking lever 2 with the vertical plane containing the straight line passing by the hinging points of the rod or rocking lever 3.
- device 1 comprises two rocking rods 2 and two rocking rods 3 disposed symmetrically relative to a horizontal axis of symmetry 1a of the whole device 1.
- first and second hinging elements are shiftable from the open condition in which they are spaced apart from each other, to the closed condition in which they are at least partly nested into each other thereby greatly reducing the overall dimensions of device 1.
- the first and second hinging elements 8 and 9 are originally made up of a material having a different, preferably lower, hardness than the material of the rocking levers. If the latter are made of steel, advantageously the hinging elements are of an easily and precisely workable material, such as brass or aluminium.
- attachment sets 6 and 7 comprise a first support body 10 and a second support body 11 respectively, to be engaged to door 4 and post 5 by anchoring means, defined by lag screws for example, and connecting and adjusting means 12 interposed between the support bodies 10 and 11 and the corresponding hinging elements 8 and 9.
- the first support body 10 has a base face 10a oriented vertically in an operating position and adapted to be coupled with a corresponding surface of a hollow formed in door 4, and mating regions 10b located in vertical planes inclined to the base face 10a and adapted for coupling with mating edges 8a of the first hinging element 8.
- inclination of edges 8a and of the mating regions 10b enables an easy engagement or disengagement by sliding between the first support body and the first hinging element 8.
- inclination of edges 8a also enables a variation in the mutual position between the first support body and the first hinging element, with possibility of locking by means of a fastening and adjusting screw 12a.
- screw 12a operates at a slot 12d formed in the hinging element 8, so as to enable a translation of element 8 itself in a direction parallel to the inclined vertical planes defined by regions 10b and the corresponding edges 8a. Practically, during adjustment of the portion of element 8 with respect to the support body 10, slot 12d undergoes a displacement relative to the fastening screw 12a.
- the first support body 10 has a substantially flattened conformation and can be secured to door 4 by lag screws oriented according to an anchoring axis 13 transverse to the main face 4a of door 4.
- the first support body 10 seen in top view in an operating position, has a right-angled conformation defining two base faces 10a and 10c orthogonal, to each other and to be coupled by a right-angled matching hollow for example, formed in door 4.
- the lag screws constituting the anchoring means to the door are also disposed at the base face 10c which is transverse to the main face 4a of door 4 and therefore are oriented according to an auxiliary anchoring axis 14 parallel to the main face 4a itself.
- the first support body 10 is very steadily connected to the door, also due to the fact that very long screws can be employed along the auxiliary anchoring axis 14, in spite of the particular conformation of the door edge region.
- the second support body 11 is defined by a base disk of partly circular conformation to be fitted in a matching seat formed in post 5.
- the second hinging element 9 Susceptible of engagement with the base disk 11 is the second hinging element 9 which, in addition to being provided with fork-shaped seats 9a for the ends of the rocking rods 2 and 3, also has an anchoring slot 9b which, in an operating condition, extends along a predetermined, preferably vertical, axis 9c.
- the connecting and adjusting means of the second hinging element 9 comprises a main connecting and adjusting screw 12b to be locked to a predetermined position of slot 9b, which enables adjustment of the door in a vertical plane. More specifically, the slot 9b has a longitudinal extension axis 9c along which the relative movement of the screw 12b can take place, thereby obtaining the possibility of latch-like moving the second hinging element 9 relative to the second support body 11 (i.e. with a movement involving up and down sliding).
- the connecting and adjusting means of the second hinging element 9 also comprises an auxiliary adjusting screw 12c having a thrust end abutting against the base disk 11 which enables the second hinging element itself to be locked to a predetermined and varying distance from the base disk in a horizontal direction.
- the invention achieves important advantages.
- attachment sets each comprising two components, for connection to the door and the post enables the materials of same to be easily diversified in respect of those of the rocking rods, and the production cycles of the whole device to be optimized.
- the support bodies can be made of aluminium or other non-ferrous material alloys by adopting die-casting processes.
- the hinging elements can be made of brass and submitted to a quick and precise mechanical working.
- the rocking rods may consist of steel elements obtained by a quick cutting-out operation. In this manner the overall production costs are consequently greatly reduced.
- the surface hardness of the rocking rods may be different from that of the hinging elements and this enables frictions and wear of the regions intended for sliding on each other to be reduced.
- the connecting and adjusting means interposed between the support bodies and relative hinging elements enables the door position to be easily and quickly adapted to the post during both the closing and opening steps.
- the above-described second embodiment of the support body to be coupled with a door enables a particularly strong anchoring to be made, which anchoring is therefore very reliable and durable also in case of rather heavy doors.
