Abstract
The invention relates to a cup member of a foldable furniture hinge, provided with
two rotary fastening elements. To fasten it, it provides a radially extending retaining
wing (1a, 1b) on each side of a longitudinal axis of the hinge, which resides radially
on the inner side of a contour of a respective receiving blind hole in a non-installed
state of the hinge and on the outer side thereof in an installed state. According to the
present invention, the wing (1a, 1b) is positioned under a specific angle with respect
to a cup element in order to obtain a smooth arcuate path of moving of a tip portion of
said wing relatively to said stationary cup element, when incorporating, said path thus
approaching to the outer surface of said furniture panel i.e. in a direction contrary to
the direction of tightening the respective cup member. Said wing (1a, 1b) mates in an
abutting manner a supporting face (4) of a cup core. Two supporting faces (4) reside
in a common plane that forms an acute angle (α) with the surface plane of the
furniture panel, with a tip thereof lying on the side of the cup member averted from
the hinge arm (R).
Description
This patent refers to a cup member of a foldable furniture hinge, provided with
two rotary fastening elements, with each of them providing a radially extending
retaining wing, which, in a non-installed state of the hinge, resides radially on the
inner side of a contour of a respective receiving blind hole and in an installed state it
resides on the outer side thereof.
A cup member of a foldable furniture hinge, provided with two rotary fastening
elements, of the kind set forth above is known on one hand ("Prior Art") from the
patent US 5,577,297 (Lautenschläger) and, on the other ("State of the Art"), from the
Slovenian patent application No. P 2002 0 0162 (LAMA) and the European patent
application No. 03468002.5 (>EP 1 375 801; will be published on 02.01.04) based on
the former, whereas the latter two have not been published on the date of filing of the
present application.
In said solutions of the Prior Art and State of the Art, said cup member of a
foldable furniture hinge, provided with two rotary fastening elements is fastened into
the material body of a furniture panel by means of two spindles of said cup member,
each said spindle providing to this end radially extending blade-type wings positioned
along a virtual screw line, with said wings, when rotated, protruding into the material
of the furniture panel, whereby, due to said virtual screw line-existed attacking angel
of said wings, the respective cup member is tightened against a bottom surface of said
receiving blind bore.
In order to successfully retain the cup members constructed according to the
aforementioned solutions a sufficiently compact, firm material of a furniture panel
must obviously be present.
Meanwhile, researches in the field of manufacturing furniture panels have been
oriented to economize the consumption of wood. It is a practical result of such
tendency that glued three-layer compound panels to form furniture panels are
produced, whereby said two firm, preferably thin, outer layers are made preferably of
plastics, and a comb-type filler made of a paper or paper-like material, whereby the
total thickness of said compound panel is preferably smaller than that of wooden
filler-type panels and can amount to merely 12 mm.
Comb structures of the aforementioned type are obviously not strength-characterized
materials, which could, after the protrusion of a blade into said
materials, together with said blade-type wings of the Prior Art and State of the Art
compose a satisfactory retaining relation between a hinge cup member and a furniture
panel.
All that arose a question of research of how to modify said known cup member
of a foldable furniture hinge, provided with two rotary fastening elements in order to
retain it in a furniture panel made in the form of a glued three-layer compound panel
having two firm thin outer layers and a comb-type filler, whereby a manufacturing
fact has to be considered that a disturbing burr appears on the inner side of the
respective cover plate of the panel, when making a blind bore to form a receiving
place to install a respective cup member with said bore.
An incorporation state of a hinge cup member as set forth above is associated
with an analogy of a concealed dry bond retaining e.g. electrical parts of installation
material, and that is why, as a technological background, the respective solutions have
been examined as well. As a rule, said solutions are based on the application of levers.
In fact, the retaining techniques based on tightening of levers by their acting
from the inner side of a cover plate of a panel can be applied with furniture hinges,
however, it is practically inadequate; additionally, the fact that said burr is constantly
present and not definable in advance represents an insurmountable difficulty for said
levers; the expected thickness of said cover plate of said furniture panel is also not
defined in advance.
Thus a retaining technique based on rotary wings as defined in the introductory
section of the present description was preserved.
The primary goal of this invention is to modify a spindle part of a cup member
of a foldable furniture hinge, provided with two rotary fastening elements in order to
retain said cup member in the incorporated state by means of a wing acting on the
inner side of a cover plate of a three-layer panel having a non-firm filler.
According to this invention, said goal of a cup member as set forth above is
achieved by means of two wings, with each of them being positioned at a specific
angle with respect to a cup element of said captioned cup member in order to obtain,
when incorporating, a smooth arcuate path of moving of a tip portion of said wing
relatively to said stationary cup element, said path thus approaching to the outer
surface of said furniture panel i.e. in a direction contrary to the direction of tightening
the respective cup member.
The tightening effect according to the invention is thus contrary to that
embodied by the wings of Prior Art and State of the Art wherein, when incorporating,
a tip portion of a wing is smoothly shifted in the direction of putting in and tightening
of the respective cup member.
Besides, said wing according to this invention mates, in an abutting manner, a
supporting face of a cup core or a respective section of said cup element serving as a
cup core, whereby said cup core being a separate constructional component can be
made of plastics or a metal and embodied as a monolithic or a two-part constructional
component.
A difference to Prior Art and State of the Art lies is that said wing according to
this invention does not act with the material body of the furniture panel.
Accordingly, two supporting faces of the cup core made of plastics, with which
the two wings act, are in question, whereby said faces reside in a common plane
forming together with the surface plane of the furniture panel an acute angle with a tip
thereof lying on the side of the cup member averted from the hinge arm.
Thereby a retaining quality of the cup member is achieved that is in ideal
proportion to a momentum of pulling out the cup member, generated by the hinge
arm.
Hereinafter, the feasibility of the proposed invention is proved on the basis of
an embodiment of a preferred cup member, the description of which is based on the
enclosed drawings where
- FIG. 1
- is a plan of an inventive rotary fastening element-type cup member of a foldable furniture hinge,
- FIG. 2
- is an elevation of the hinge cup member of FIG. 1,
- FIG. 3
- is an overhead projection of a monolithic cup core of the cup member of FIGS. 1, 2,
- FIG. 4
- is a section along the line IV-IV of FIG. 3,
- FIG. 5
- is a plan to FIG. 3, and
- FIG. 6
- shows an analogous projection, a section, and a plan as in FIGS. 3 to 5, yet regarding a two-piece cup core.
In FIG. 1, two retaining wings 1a, 1b, more specifically the wing 1a in a
retaining position and the wing 1b at stand-by position are drawn in dotted lines. The
figure shows a blade-type construction of the wings 1a, 1b with practical importance
of said blade-type shape being in that the wing also functions as a unilaterally fastened
girder of a substantially constant bending strength, from which it is expected to
achieve an elastic adaptation of the girder to the given dimensions available for the
installation, by means of the respective elastical flexibility.
It is clearly evident from FIG. 2 that with respect to a surface of a furniture
panel (not shown) having a thickness A the wings 1a, 1b are positioned in an inclined
way. In a preferred embodiment of a cup member as shown, two supporting faces of a
cup core (details: hereinafter), the wings 1a, 1b act with, reside in a common plane,
which forms an angle α (alpha) with the surface of the furniture panel, with said angle
having its tip residing on the side of the cup member averted from a hinge arm R.
It is understandable that according to the inclined arrangement of the wings 1a,
1b, a rotary axis 2 of each rotary element 3a, 3b, said rotary element being preferably
a rivet in this embodiment, is arranged normally to the wings 1a, 1b, i.e. also in an
inclined way, with the wing 1a, 1b being connected to said rivet in a manner that there
exists no relative rotation between them. In the shown embodiment, the rivets 3a, 3b
comprise screw driver heads, which does not mean that other embodiments, such as
those providing levers of the prior art instead of the heads 3a, 3b, are excluded.
In the stand-by position of the hinge, the wing 1a, 1b resides on the inner side
of a circular contour K of a cup element of the respective cup member (the position of
the wing 1b in FIG. 1). By rotating the rivet 3a, 3b, each of them in a specific
direction, the free tip portion of the wing 1a, 1b smoothly approaches to the inner side
of a cover layer of said furniture panel and, after having reached it (the wing 1a in
FIG. 1), it begins to get elastically deformed if further rotated.
In a built-in state, the position of the hinge is determined by nesting the cup
element of the cup member in an appropriate recess (hole, receiver) made in the
furniture panel, and the cup member is then fastened therein on the basis of two
elastically deformed wings 1a, 1b that, from the inner side, thrust the cover layer of
the three-layer panel and thus tighten the respective cup member to said panel.
When discussing the supporting plane of the core, as evident from FIGS. 3 to 5
for a monolithic core made of plastics and in analogy from FIG. 6 for a two-piece core
made of plastics, they both belong to the respective cup member, in each case a face 4
is in question, the wings 1a, 1b act with, the faces 4 residing in a common plane
forming an angle α with the surface of the furniture panel.
