Definitions
- a coupling piece for frame-works, panels or the like is A coupling piece for frame-works, panels or the like.
- the invention relates to a coupling piece for frame-works, panels or the like, adapted to be connected, in a corner of a frame-work, panel or the like, with border channels or edge portions thereof, said coupling piece comprising two, in particular mutually perpendicular, legs, at least one thereof being provided with a recess having a coupling pin directed parallel to a border edge of said leg for coupling, by means of a coupling element, said coupling piece with another coupling piece having a leg positioned against the corresponding leg of said first coupling piece, a rotational movement around said pin being possible, a border portion of said legs being rounded around the pin in question in such a manner that the roundings of both mutually coupled legs are allowed to roll around each other.
- Such a coupling piece is known from EP-A 0 068 583.
- a fixed pin is provided in a recess of a leg, said pin being situated in the longitudinal median plane, the coupling element being formed by a resilient U-shaped clip being adapted to be clamped around two pins of coupling pieces arranged adjacent to each other; the roundings are substantial ⁇ ly cylindrical around the pin axis.
- the coupling piece is characterised in that the coupling element consists of two pins interconnected by a bridge, in that the leg in question is provided with two parallel bores which are symmetrical in respect of the longi ⁇ tudinal median plane and open into the recess in question, in which bores a pin of a coupling element fits in a slidable way, the interaxial distance of the pins of a coupling element being substantially equal to the interaxial distance of said bores, and in that the rounding consists of two parts having an axis coinciding with the axis of the adjacent bore, and having a radius which is substantially equal to half the interaxial distance of said bores, all this in such a manner that, when interconnecting two coupling pieces by means of such a coupling element, a rotation around the axes of both pins with a rolling movement of the roundings in question on each other is allowed.
- each recess such a coupling element can be provided, and, in the case of aligned panels, a double coupling and, thus, an unambiguous locking can be obtained by means of the mutually off-set coupling elements of adjacent coupling pieces.
- one pin of a coupling element can have such a length in respect of the length of the recess that said pin, when longitudinally shifted in a bore, cannot be pulled out of said bore, the other pin being so much shorter that, when shifting said coupling element, the latter pin can be swung out of said recess and can be shifted into another bore and vice versa.
- a coupling element can already be provided beforehand, said element then remaining unlosable with the coupling piece, and by shifting said coupling element the shorter pin can be engaged with an adjacent bore of another coupling piece.
- said bores can be open at least at the end opposite to said recess at the inner side of the leg, in order to allow tilting the longer pin present therein in such a manner that it can be pulled from the bore or can be inserted therein,' and the terminal portion of the leg in question can also be profiled in such a manner that, when applying the coupling piece on a frame-work channel or panel, an inserted longer pin will be secured against tilting.
- This allows to insert a coupling element into the recess, said element then remaining locked after providing the coupling piece on a frame-work portion or panel , without impeding the shifting of said coupling piece in the bore in question.
- the longer pin can be provided with a terminal bulge, and stops can be provided in said bores which, together with said bulge, will limit the shifting of said pin in said bore.
- the roundingscan be knurled the knurlings of two roundings belonging to two parallel bores will be off-set by half a knurl distance, so that the knurlings of two coupled coupling pieces will mesh; in this manner a gear-wheel effect will be obtained insuring a uniform hinge effect.
- Fig. 1 a lateral view, partially in section, of a coupling piece of the invention
- Fig. 2 a top view of the coupling element of Fig. 1;
- Fig. 3 a section along the line III - III of Fig. 2;
- Fig. 4 a lateral view of a coupling element for such a coupling piece
- Fig. 5 a lateral view of two intercoupled coupling pieces of Fig. 1;
- Figs. 6A and B top views of coupled coupling pieces of Fig. 5 in two different positions;
- the coupling piece 1 shown in Figs. 1..3 comprises two mutually perpendicular legs 2 forming each others mirror image, said legs being substantially U-shaped in section, and having a terminal portion 3 which is adapted to be inserted into a hollow frame-work channel 4 or the like, a resilient locking tongue 5 serving for locking such a channel. Said locking tongue 5 can be pushed away through a hole 6 for releasing the locking.
- each leg is provided with a recess 7.
- two apertures 9 are formed symmetrically in respect of the longitudinal median plane of the leg 2, said apertures opening into the cavity 10 of the leg 2.
- the wall portion 11 of the leg 2 joining the recess 7 is, as will appear in particular from Fig. 3, rounded near the outer edges 11* , and is, there, provided with a knurling or toothing 12.
- the teeth of both are mutually off-set by a half tooth distance.
- the radius of the roundings 11 l is equal to half the interaxial distance of the apertures 9.
- Fig. 4 shows a coupling element 13 consisting of a bridge piece 14 provided with two parallel pins, viz. a longer pin 15 and a shorter pin 16.
- the interaxial distance between said pins corresponds to the interaxial distance of the apertures 9, and the thickness of said pins substantially corresponds to the width of said apertures.
- the longer pin 15 has a thinner terminal portion 15' terminating in a thicker head 15" having a thickness which, again, is equal to that of the initial portion of the pin 15.
- Such a coupling element 13 can be inserted with the longer pin 15 obliquely into the recess 7 and through an aperture 9, since the adjoining cavity 10 is open at its lower side.
- the pin 15 can be turned upright, and can be shifted further in the axial direction of the aperture 9. Stops 17 can cooperate with the head 15", and determine an inserted and retracted position of the coupling piece.
- the shorter pin 16 can then be inserted into the adjacent aperture 9.
- Figs. 5 and 6 show two coupling pieces 1 interconnected by means of a coupling element 13, the longer pin 15 thereof being inserted in one coupling piece, and the shorter pin 16 in the other one. Since the interaxial distance between the pins 15 and 16 is equal to the interaxial distance between the apertures 9, and the radius of the roundings 11' is half said interaxial distance, the coupling pieces can be rotated around the axes of said pins 15 and 16, the teeth 12 of said roundings which are off-set by half a tooth distance will intermesh. If, as shown in Fig. 6B, the coupling pieces are rotated flatly against one another, the teeth 12 on the lateral walls provide a correct alignment. This is the position in which inserting the shorter pin 16 into an aper- ture 9 of the adjoining coupling piece can be done in the easiest way.
- a second coupling element 13 can be inserted if desired for unambiguous ⁇ ly locking said position as shown in Fig. 6A at 13'. It will be clear that, in the same manner, also at the other side of the coupling pieces of Fig. 5 additional coupling pieces 1 can be provided.
- Fig. 7A shows the connection according to Figs. 5 and 6B after rotation by 90°
- Fig. 7B shows how in the position of Fig. 7A a third coupling piece can be added.
- a fourth coupling piece can be provided.
- the legs 2 are mutually per- pendicular, it is also possible to provide said legs at a different angle, and even to interconnect both legs of a coupling piece by means of a hinge allowing to direct them at arbitrary angles. Furthermore it will be clear that in Fig. 7 the interconnected coupling pieces 1 can be mutually rotated for obtaining corresponding orientations of the respective frame-works, and that, then, also more than four coupling pieces can be interconnected.

Abstract
Une pièce d'accouplement pour charpentes, panneaux ou structures analogues, adaptée pour se fixer dans un coin desdites structures, comprend deux branches dont au moins une est pourvue d'un évidement possédant une clavette d'accouplement orientée parallèlement à un bord marginal de ladite branche à des fins d'accouplement, au moyen d'un élément d'accouplement. Ladite pièce d'accouplement présente avec une autre pièce d'accouplement une branche positionnée contre la branche correspondante de ladite première pièce d'accouplement de manière à permettre un mouvement rotatif autour de ladite clavette. Une portion marginale desdites branches est arrondie autour de la clavette en question de telle manière que les arrondis des deux branches mutuellement accouplées puissent rouler l'un autour de l'autre. L'élément d'accouplement (13) consiste en deux clavettes (15, 16) interconnectées par un pont (14), la branche (2) en question est pourvue de deux alésages (9, 10) symétriques par rapport au plan médian longitudinal et débouche dans l'évidement (7) en question. Dans lesdits alésages (9, 10) s'emboîte de manière coulissante une clavette (15, 16) d'un élément d'accouplement (13), la distance interaxiale des clavettes (15, 16) d'un élément d'accouplement (13) étant sensiblement égale à la distance interaxiale desdits alésages (9, 10). L'arrondi (11) consiste en deux parties présentant un axe coïncidant avec l'axe de l'alésage adjacent (9, 10), et ayant un rayon sensiblement égal à la moitié de la distance interaxiale desdits alésages (9, 10), et ce de manière à autoriser, lors de l'interconnexion de deux pièces d'accouplement (1) au moyen d'un tel élément d'accouplement (13), une rotation autour des axes des deux clavettes (15, 16) avec un mouvement de roulement des arrondis (11) l'un sur l'autre.
