SI21667A - Arc-shaped part of furniture joint hinges on rotating attachment elements - Google Patents

Abstract

Subject of the invention is an arc-shaped part of furniture joint hinges on rotating attachment elements. On each side regarding the longitudinal axis of the hinge there is one radial leaf (1a, 1b) for its attachment, which in the non-integrated position of the hinge is located radially on one side and in the integrated position radially on the other side of the contour of the accepting bearing. Regarding to the pot the leaf according to the invention is set at an angle, so that by rotating it, during installation, its top is with regard to the fixed pot moving along an arc by approaching the external surface of the furniture panel, this means in the opposite direction to the one of inserting or stretching the discussed arc-shaped part. Upon this, the leaf cooperates with the fitting surface (4) of the plastic core by fitting to it. The fitting panels are located in a common plane, which is at an angle alpha with the top of the arc-shaped part, located away from the hinge handle (R).

Earthen hinged furniture hinge on rotary fasteners

The subject of the patent is a potted part of a hinged furniture hinge on rotatable fasteners with a radially positioned fastener in each case, which is radially extraneous in the non-built state of the shamii and radially beyond the contour of the receiving bearing in the built-in state.

The pot of articulated furniture hinges on the swivel fasteners of a particular type is known on the one hand (state of the art) from US patent 5,577,297 {Lautenschlager) and on the other (the state of the art) from patent SI application no. P 2002 0 0162 {LAMA) or EP-based patent application no. 03468002.5, which were not yet published on the date of filing of this application.

For the aforementioned prior art, the pot of the hinged furniture hinge is anchored or anchored to the rotary fasteners in the material of the furniture panel by rotating the corresponding anchors (two) of the spindles, each component of which are radially in each case, to the respective pot. the blades placed in a helix, said blades bent or dipped into the material of the furniture panel, and on the basis of the bends of the blades in the sense of the helix, the respective pot is tightened towards the bottom of the receiving bunk.

It is in the palm of your hand that a prerequisite for the successful anchoring of the above sketched solutions is the existence of a suitable compact structured material of the furniture panel.

Meanwhile, the technique of making furniture panels went in the direction of saving wood materials. The result of this tendency is glued three-layer composite panels with solid, generally thin outer layers, usually plastic, and honeycomb type filler, typically of paper or paper-like material, the overall thickness of the panel being generally less than that of wood-based panels and may it is only 12 mm only.

It is in the palm of your hand that the honeycomb of the type mentioned above is not the supporting material by which the knife blades of the prior art, once embedded in it, would establish the supporting anchorage of the respective pot part and the panel in question.

By itself, then, a development question arose as to how to modify a known potted hinge furniture hinge to rotatable fasteners so that it can be anchored in three-layer glued, two solid, thin roof panels and a honeycomb-type intermediate panel, with account must be taken of the fact that when creating the blind hole as a bearing for receiving the pot in question, an interfering burr occurs on the inside of the cover layer of the furniture panel.

The above sketched installation state of the pot hinge points to an analogy with dry-mounted flush mounting, such as electrical installation components, and therefore we have explored the relevant solutions as a technological background. These are generally based on leverage.

Anchoring on the principle of lever tightening with leverage is portable to the area of furniture shamis, but practically useless; Not only do we have to deal with the previously mentioned indeterminate scab, which can be an insurmountable obstacle against levers, the thickness of the cover of the furniture panel is not uniquely determined.

Thus, it remained with the rotary wing concept as defined by the prior art.

The object of the present invention is then to modify the spindle assembly of the hinged furniture hinge onto the rotary fasteners so as to modify the spindle assembly blades in the built-in condition by holding it in place, i.e. by fitting to the inside of the deck layer of a three-ply furniture panel with a non-supporting core.

The task of the invention for the pre-defined pot part is solved by the fact that each wing relative to the pot of the pot in question is positioned at an angle such that during its rotation, when installed, its tip relative to the stationary pot is continuously moving in an arc with an approaching outer surface furniture panel, ie. in the opposite direction to the insertion or tightening of the pot in question.

The effect of fastening according to the invention is thus opposed to the effect of fastening with the wings of the prior art, when the mounting tip of the wing is constantly moving in the direction of insertion or tightening of the respective pot part.

The blades of the invention are further cooperated in a manner that fits with the contact surface of the core or as the center of the serving portion of the respective pot part, where, in the case of the core as a separate part, it may be of plastic or metal and one or two parts.

The difference from the prior art, therefore, is that the wings according to the invention do not interact with the weight of the material of the furniture panel.

The contact surfaces of the plastic core with which the wings cooperate are therefore two and lie in a common plane which, with the plane of the furniture panel, encloses a sharp angle with the apex on the side of the pot, lying away from the shamir lever.

In this way, the anchoring moment of the pot part is ideally proportional to the moment of extraction of the pot from the hinge arm.

The feasibility of the invention is further demonstrated on the basis of an embodiment of the present pottery, the description of which is based on the attached sheets of sketches in which they show

FIG. 1 is an inventive pot of articulated furniture hinge on rotary fasteners, in plan view,

FIG. 2 is a potted part of FIG. 1 in outline projection,

FIG. 3 shows a plastic core in a one-piece design of a pot with FIG. 1, 2, in ceiling projection,

FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 3,

FIG. 5 is a plan view of FIG. 3, and

FIG. 6 is an analogue to the drawings of FIG. 3 to 5, touching the plastic core in a two-piece design.

In the FIG. 1 what dashed anchor wings la, lb i.s. wings la in the built-in condition, wings lb in the prep. The blade design of the blades la, lb is presented, the practical meaning of which is that the blades serve as a one-sided bracket of essentially constant bending strength, so that due to the elastic bending in question, an elastic adaptation to the given mounting dimensions is expected.

FIG. 2 is clearly illustrated with respect to the plane (not shown here) of a panel of thickness A, an oblique arrangement of the wings la, lb. In the preferred design of the pot as shown, the contact surfaces of the core (the details below) with which the wings la, lb cooperate lie in a common plane which, with the plane of the furniture panel, wraps as a (alpha) with the apex on the side of the pot, which lies away from the shamiric lever R.

It is understood that in accordance with the oblique arrangement of the wings la, lb is oblique, i.e. perpendicularly to the wings la, lb, there is also a rotary axis 2 of the respective rotary element 3a, 3b, which is in the preferred case a rivet which is connected to the wing la, lb so that there is no relative movement between them. In the present case, the rivets 3a, 3b have screw heads, which does not preclude other embodiments, such as replacing the head 3a, 3b with a prior art lever.

In the initial hinge state, the wing la, lb is located within the circular contour K of the pot of the pot in question (in Fig. 1 the case of wing lb). By rotating the rivets 3a, 3b each in their own direction, the free end of the wing la, lb on the inside of the furniture panel is federally closer to the cover layer thereof and, upon contact with it (in FIG. 1, with the la wing), begins to elastic upon further rotation deform.

In the mounted state, the hinge position is determined by holding the pot of the pot part in the adapted notch (hole, bed) in the furniture panel, and is fixed on the basis of two forces of elastically deformed wings la, lb, which press from the inside to the roof layer of the three-layer panel and consequently the respective press the pot part to the panel.

As shown in FIGS. 3 to 5 for the one-piece and analog FIG. 6 is the two-piece plastic center of the pot in question, the contact surfaces of the core with which the blades la, lb interact and which lie in a common plane which, with the plane of the furniture panel, encloses as a, in each case 4.
