Patent application

"Quick assembly hinge, especially for furniture."

The present invention relates to a Quick assembly hinge, in particular for furniture.

The modern series production of furniture, such as kitchen furniture, requires the greatest possible Automation and the fastest possible and elementary intervention on the part of the furniture fitters.

Hinges are known for the articulated connection between furniture and wing, of which at least one wing is introduced into a seat designed for this purpose on the furniture part and held there with fastening screws.

609839 / Ü372

Such a fastening system has different Defects. Above all, it should be noted that the material used to manufacture furniture nowadays is often wood chipboard are. Although this material has good properties of a general nature, it does have one limited ability to hold those recorded by him Fastening screws. Above all, it is not permitted to place a fastening screw in the same seat several times screwing in and out, as the chipboard yields and the fastening screw does not provide any guarantee.

These deficiencies appear particularly in those cases in which the known return spring hinges are used by which a considerable load is clearly transferred from the wing to the furniture part.

The furniture sash must be attached to the free sash of a hinge with special care was attached to the fixed part of the furniture The two parts remain well matched to each other after the fastening work has been completed.

There is a desire among furniture manufacturers to have a hinge with at least one wing can be installed and removed on the corresponding furniture part with one elementary and quick process. To notice is that this wish finds, among other things, a clear justification that very often the fixed body the serial furniture can be made in a single color, while the wings in different, the buyer's request appropriate colors. The advantage given by the possibility is therefore understandable is to install the wings with the desired color on the already prefabricated furniture body or by others

509839/0372

to replace with different color.

The object of the present invention is to meet the mentioned requirements by providing a hinge is created that can be quickly installed with one of its wings on the corresponding furniture part, without the need for special tools and without the risk of changing the material of the piece of furniture in particular to be damaged in the event of repeated installation and removal.

This object is achieved according to the invention through the creation solved a hinge for furniture comprising at least one wing consisting of an elongated part, which is slidably inserted into a seat capable of being attached to the fixed piece of furniture, the displacement between the Fitigelteil and the corresponding seat by a manually releasable Snap connection can be locked.

In order that the objects and features of the present invention may be better understood, the following are examples Described embodiments shown in the accompanying drawings.

In the drawings show:

Figure 10 is an exploded view of a device according to the invention Hinge;

FIG. 11 shows a section through the connection system between the hinge wing and the corresponding seat.

The hinge shown in Figures 1-6 is designed in the manner of a four-sided joint and comprises a wing 10 with a double bolt 11, 12, the are hinged to the articulated lever 13 and 14, which in turn 15 and 16 are hinged to a wing 17. An extension of the articulated lever I4 is supported on a stand 18, which rests with its resilient telescopic arms against a traverse I9 of the wing 17. The springy effect of the stand 18 causes the hinge to be self-contained and resilient, starting from an intermediate Dead center, to be arranged in the open and closed position. the structural joint arrangement is not included in the present invention and is therefore not described in more detail, as it is known in and of itself to the person skilled in the art.

The wing 10 consists of a pot part 20, which is intended to be in a corresponding seat of the piece of furniture, possibly also by means of the flanges 21 performed fastening screws to be added.

The hinge wing I7 is one embodiment in particular according to the teaching of the invention. It consists of an elongated part 22 with a substantially U-shaped Cross-section inserted into a housing-shaped seat 23 will.

From the bottom of the seat 23 are facing Gevrndebolzen 24 to bestiirmt e ~ nd, "nit a purposeful adhesive ¹ × medium in the corresponding wall furniture introduced to be.

In the seat 23 a compression spring 2 5 is added, which supported on a bolt 27, acts against a pin 26.

The hinge described is intended to be attached with its wing or band 10 to a piece of furniture, e.g. to be attached to a furniture wing.

The articulation of the furniture wing to the furniture body is done in a simple manner by introducing the extended Part 22 into the seat 23. In this process, the bevel 28 lowers the pin 26, which snaps into the bore 30, whereby the part 22 is determined.

By subsequently acting on the screw 31, the position of the furniture glider can finally be adjusted can be adjusted on the wing posts. The effect of the screw head on the seat 23 removes namely the part 22 of the seat 23 and therefore of the furniture panel to which the hinge leaf has been attached.

The removal of the furniture wing can be done in a simple manner by acting on the pin 26 in that this is pressed into its seat, whereby it emerges from the through hole 30 and frees the part 22.

Through-holes 36 in part 22 and such 32 in the wall of the seat 23 allow the use of a screw for increased security, this screw engaging the plate on which the seat 23 itself is attached. Even if this screw is not required, it allows an even more stable fastening of the hinged ice, although it can only absorb very limited loads. ^v -, 5, -

Figures 7-9 show views similar to those of the figures 4-6 are similar, but they represent a variant of the hinge according to the invention. In this version is the definition of the wall 22 in the seat 23 by means of a Bolt 33 achieved, which is extended telescopically by the action of the spring 34. The ends of this bolt 33 find / in the holes 35 of the seat 23 inclusion.

In this case, too, the part 22 is fixed by inserting it into the seat 23 and compressing the Pin 33 is effected by chamfers 37. The attachment of the part 22 takes place in turn by the action of pressure Ausserv4uf the bolt ends, so that its length is shortened.

The embodiments shown are exemplary, the essential idea according to the invention being at least to make a hinge wing in two mutually compatible parts by means of a snap connection. These Snap connection is in particular a plug connection. The complementary configurations of parts 22 and 23 can be very diverse. The materials used to form these parts can also be different. Be nature. For example, the part 22 could be made of metal, while the seat 23 is advantageously made of plastic could be executed.

In Figures 10 and 11, a further embodiment of the hinge according to the invention is shown, that of two Wings or bands is formed, which are connected to each other as an articulated square and is a total of the Reference number 40 indicated.

509839/0372

The hinge 40 structurally consists of a wing 41 which is intended to be complemented with a Seat 42 to be connected.

More precisely, the wing 4I comprises a part 43, which is fastened in a corresponding seat of the piece of furniture. An actual wing 41 is hinged to part 43, which consists of a cylindrical, partially hollow body 44 which is partially a known hinge mechanism contains. The cylinder 44 ends with a tapered cross section 45> which widens to a frustoconical anchoring head piece 46. With the reference number 47 a screw is specified, which is used as an adjusting screw the final position of the furniture wing in relation to its post, also as a locking screw of the mutual Rotation between the wing and the corresponding seat is used.

The seat 42 includes a tubular body that is designed in addition to that 44 and preferably consists entirely of plastic. From the body of the Seat 42 are sawtooth-shaped inserts 48 for attachment of the seat itself in the corresponding furniture wall.

According to the invention, the body 42 ends with a partially narrowed inner cross section 49 * which can be elastically expanded is. The cross section 49 complements that 45 of the wing 41 and its resilience is due to a number of Slits 50 cut along the generatrices of the tubular body. The cross section 49 ends with an extension 5I. The body 42 has In addition, at the end facing away from the cross section 49 one

- 7th

509839/0372

Incision 52 with which the head piece of the screw 47 is engaged.

It is obvious that when the wing 41 in its seat 42 (Figure H), the head piece 46 first radially expands the flexible cross section 49, with then this as soon as the head piece 46 the extension 5I reached, snaps into the complementary, narrowed cross-section. The components 41 * 42 are thus stable with one another tied together. If it is necessary to remove the wing from its seat, it is sufficient with a suitable one Tool to enlarge the extension 5 *.

Thus, a snap connection becomes simpler and more economical in construction and completely more reliable in operation achieved.

The principles of the present invention are of course also applicable to hinges with two articulated levers which are of a different nature than those described. Based on the teaching according to the invention can also Hinges made with a single hinge pin or generally different according to the known technology be trained.
