Abstract

The invention relates to a fitting for connecting two socket cover strips which engage the adjacent ends in two fitting grooves.

The state of the art is such a fitting with fixed grooves with a crooked base. Disadvantages of this fitting are fixing it to a certain inside or outside angle and the need to miter the ends of the strips.

The object of the invention is therefore to eliminate the rigidity of the angle between the fitting legs and to make miter cuts unnecessary.

This object is achieved forming both grooves (26) in each case one of two separate fitting parts (14 and 16) which are mutually rotatable relative to ^o about a vertical pivot axis (L) depending on an angle of approximately 90th

The advantage of this solution is the possibility to set any interior angle from 90 ^o to almost 180 ^o and to be able to cut the bar ends straight.

Description

The invention relates to a fitting for releasably connecting the mutually adjacent ends of two cover strips for plinths of built-in furniture, in particular kitchen furniture, with hidden adjustable feet; with two vertical grooves for receiving one strip end each, which form an inside angle of 90 ^o or 135 ^o , measured in a horizontal plane, depending on whether the fitting is attached to a right or obtuse inside or outside corner of the base, the can jump back and forth and run diagonally. - The known fittings are designed accordingly.

Of the known obtuse angle fittings, it is disadvantageous that they permit only a certain internal angle of usually 135 ^o, which the two abutting cover strips are intended to form, which are clamped to the adjustable feet by means attached to the strips back clip which the body underbody of any free-standing installation cabinet support on the floor; and that (regardless of the size of the interior angle) the ledge ends to be joined must be mitred, either in the joinery or at the installation site, where rework and the use of joint putty are often required to compensate for dimensional tolerances. In order to avoid this, joiners occasionally supply finished plinths made from fittings and from these adapted, mitred and glued trim strips glued to the fittings. Such finished bases are difficult to transport due to their bulkiness and changes in the installation conditions in the meantime are hardly adaptable, since it is essentially a rigid structure.

The invention is therefore based on the object to provide a said disadvantages avoiding fitting of the type mentioned, which does not require any internal angle of between 90 ^o and 180 ^o allowed to produce at the installation location and a miter cut strip ends for blunt inner angle.

This object is inventively achieved in that one of the two grooves of the fitting is formed in a first fitting part, which is ^o rotatable relative approximated to a the other groove having second fitting part about a vertical pivot axis through an angle of 90th

This advantageously ensures that any desired interior angle between 90 ^o and 180 ^o , but also a right interior angle can be formed, the strip ends can be cut straight (rectangular) in any case.

The fitting according to the invention, in combination with the cover strips connected thereby, represents a polygonal movable base which can be assembled from its individual parts at a distance from the adjustable feet and then clamped in sections (strip by strip). The assembly of such a base therefore requires relatively little time.

A preferred embodiment of the fitting according to the invention is characterized by a convex circular cylindrical surface, the cylinder axis of which forms the pivot axis, and by a complementary concave cylindrical surface on the rotatable fitting part, which encompasses the convex surface over at least 90 ^o , preferably over 135 ^o . - This makes the one you want Relative rotation of the second fitting part safely and at the same time easily guaranteed.

In the preferred embodiment, the convex circular cylindrical surface is formed on a circular cylindrical third fitting part, preferably a pipe section, to which the first and the second fitting part are articulated. - As a result of this hinge-like configuration of the fitting according to the invention, both the first fitting part and the second fitting part can be rotated relative to the third fitting part (pipe section), so that only an angle of rotation of approximately 45 ^{° is} required.

In the preferred embodiment, it is provided for the articulation and limitation of the angle of rotation that the first and the second fitting part are each provided with two radial projections facing away from the groove, preferably made of elastic plastic, and the free ends of which are the edges of a horizontal, approximately 45 ^o long slot (slot). reach behind the pipe section as a third fitting part. - The above-mentioned, for example fir or mushroom-shaped, projections are simply pressed through the elongated holes and then form a lock of the first and the second fitting part with the tube piece that can only be released by force.

In the preferred embodiment, the first and the second fitting part are the same and are arranged in mirror image with respect to an axial plane of the pipe section. In this embodiment, the fitting according to the invention is particularly simple to produce and can be used universally, since one rotation of the entire fitting about the central vertical axis of the pipe piece is sufficient to produce an inside or outside corner of the base by means of the fitting.

In the preferred embodiment of the fitting according to the invention, the lateral groove walls are formed as known by two parallel flange brackets, is finally provided that the two outside flange brackets of the first and second fitting part tangent to the pipe section and with the maximum internal angle of <180 ^° with their longitudinal edges lie flush against each other; and that the two inside flange strips are flush with their longitudinal edges at a minimum internal angle of 90 ^o . - This not only avoids an overloading of the projections on the first and on the second fitting part by the slotted ends, but also a superficial smoothness of the fitting without protruding edges.

Other embodiments of the fitting according to the invention are characterized in that the two mirror-image fitting parts together form a cavity which, by means of two groove-parallel, rigid flange strips and a joint, groove fitting-parallel, movable flange strip, delimits and on the fitting side opposite this, depending on the relative position of the fitting parts is more or less open or closed to each other, the opening state being secured by a suitable filler in the cavity and the closing state optionally by a butt joint of the two rigid flange strips. - Provided that the mobility of the said movable flange strip is created in a simple manner, these other embodiments are easier to produce than the initially preferred, in particular if a circular cylindrical fitting part, in particular a piece of pipe, is provided as the filler, the third Fitting part of the preferred embodiment corresponds. Such a piece of pipe for filling the cavity can be kept available in different outside diameters for different inside angles of the fitting and, moreover, also be used with a little oversize or undersize, as long as the elasticity of the material used for fitting production, preferably PVC, allows.
In the other embodiments, the two fittings of which each have a U-shaped groove with two parallel flange strips as groove flanks and a perpendicular flange strip as the groove base, it is also provided that the cavity is limited by means of the two groove base flange strips and the two rigid flange strips each lie in the vertical surface of the associated of the two parallel groove flank flange strips, while the common, movable flange strip is articulated on the free abutting edges of the mainly at least approximately H-shaped profile of each fitting part. - Thanks to the substantially H-shaped profile, in which only the movable flange strip of both fitting parts has no share, the fitting according to the invention can be produced as an extruded profile, especially if, as provided, a cylindrical filler is used.
In the other embodiments, at least the movable flange strip and the two groove flank flange strips which articulate them are formed in one piece from the two fitting parts, and the two pairs of coplanar flange strips are each formed in one piece, the articulated flange flange being designed to be articulated or two film hinges are available as hinges Vulnerability joints can be called. In a second and a third embodiment, the two fitting parts are completely and easily manufactured as a single piece. In the third embodiment, the two rigid flange strips are coaxially curved in a circular cylindrical manner and they also overlap one another even at a right inner angle, preferably at an inner angle of 30 ^° to 145 ^° , the two cylinder axes coinciding with the imaginary pivot axis of the two mirror-image fitting parts, which results as a common line of intersection of the two groove base flange strips. - Since the two fittings are brought together here, a piece of pipe as a filler to stabilize the cavity can be omitted. In a fourth embodiment, the clear widths of the grooves for receiving one strip end each can be adjusted to the widths of the skirting strips to be connected. - This makes it unnecessary to have different fittings with corresponding clear groove widths available for different strip widths.
In the fourth embodiment, the coplanar flange strips on the one hand and the other groove flank flange strip on the other hand are positively and / or positively connected to each other, the groove base flange strip being attached only on one side, namely either to the other groove flank flange strip mentioned or to the coplanar flange strips. - As a result, not only is the desired simple width adjustment achieved, but moreover overall simple installation, in particular in problematic cases in which the strip end cannot simply be inserted horizontally into the fitting groove. In its fourth embodiment, the fitting according to the invention can be attached in front assembly, which is never ruled out even with a complicated base guide.
In the fourth embodiment, for releasable connection, a pin attached to each pair of coplanar flange strips engages positively or elastically in a space that is horizontally delimited by means of the groove base flange strip and a parallel additional flange strip on which the movable flange strip attaches the cavity for receiving the packing remains undiminished. - It is therefore possible to arrange the fitting without the two pairs of coplanar flange strips on the base corner to be formed, the strip ends at the end of the groove on the groove base flange strips Bring the rear flank flanges to the system, arrange the filler in the corner and finally press the two pairs of coplanar flange strips. The cones penetrating into the above-mentioned space are expediently designed like a fir tree, that is to say they are firmly seated, but can nevertheless be pulled out of the space.

If a spiral cylindrical fitting part is provided as a filler instead of a pipe piece, the outer end of which rests on the adjacent turn of the sheet-shaped, rolled fitting part, there is no need to keep pipe pieces of different outer diameters available, since a spiral cylindrical fitting part, starting from a maximum outer diameter, by shifting the spiral turns against each other, can be reduced to a minimum outer diameter, as is known from coreless winding.

In the preferred exemplary embodiment, the fitting according to the invention made of plastic for the releasable connection of the mutually adjacent ends (6 and 8) of two base cover strips (not shown) consists of two identical halves which are arranged in mirror image with respect to a vertical plane of symmetry (S). Both fitting halves have in common both inside and outside a circular cylindrical pipe section (10), the vertical longitudinal axis (L) of which is in the plane of symmetry (S). The pipe section (10) has a height corresponding to the height of the strip ends (6 and 8) and is provided at each end with two horizontal, approximately 45 ^o long elongated holes (12), the arrangement of which is described below in the circumferential direction.

A left first fitting part (14) in the drawing of one fitting half and a right second fitting part (16) of the other fitting half encompass the pipe section (10) as a third fitting part for about 135 ^o each. The two fitting parts (14 and 16), which, as indicated, are of identical design, have a height corresponding to the height of the strip ends (6 and 8). Each fitting part (14 or 16) facing the partial looping of the pipe section (10) complementary to the convex circular cylindrical surface (11) concave circular cylindrical surface (18), which as said 135 ^o long profile sheet is ^o rotated through 45th As a result, two vertical longitudinal edges (20 and 22) of each fitting part (14 or 16) representing the arc end points lie against the corresponding longitudinal edge of the other of these two fitting parts if they are opened as far as possible to approximately 180 ^{o or} folded to 90 ^o ; see Fig. 1 and 2. The relative angle of rotation of approximately 90 ^o between the two fitting parts (14 and 16) is thus in two relative rotation angle of approximately 45 ^o between each fitting part (14 or 16) on the one hand and the pipe section (10) on the other hand divided that on each fitting part (14 or 16) two with respect to the pipe section (10) radial and therefore eccentric projections (24) are formed, the pin-like shafts each engage in one of the elongated holes (12) and on the one or hit the other ends when the fitting parts (14 and 16) are opened or closed. By appropriately designing the edges of the elongated holes (12), a catch can be provided, when they are taken up by the shafts of the projections (24), the two fitting parts (14 and 16) form the often required obtuse inner angle of 135 ^° . Of course, this practically important angle could also be defined as the maximum angle by shortening the elongated holes (12). In this case, the longitudinal edges (20) would no longer touch when this maximum angle was reached.

A head (25) is formed on each projection (24), which engages behind the edge of the occupied elongated hole (12) in such a way that the pipe section (10) partially on the two surfaces (18) of the fitting parts (14 and 16 ) is free of play and low friction.

Each fitting part (14 or 16) has a groove (26) which is rectangular in profile and which receives one of the two right-angled strip ends (6 and 8) and, in addition to the two opposite vertical directions, in the perpendicular direction from the pipe section (10 ) is opened approximately in the radially pointing horizontal direction. Two side walls of each groove (26) are formed by two parallel flange strips (28). The two outer flange strips (28) of the first and second fitting parts (14 and 16) (forming a right-angled to obtuse-angled outer angle) tangent to the pipe section (10) and end there in the two longitudinal edges (20). The same does not apply to the two flange strips (28) on the inside which meet the longitudinal edges (22) of the pipe section (10).

The groove base (30) of each fitting part (14 or 16) supporting the two groove-facing projections (24) has one of the two concave circular cylindrical surfaces (18) which could be divided and restricted to the pipe-side end faces of the two flange strips (28) in that two unequal recesses delimited by dash-dotted lines are provided on each fitting part (14 or 16).

Instead of the one-piece protrusions (24), the groove bases (30) and the elongated holes (12) penetrating screws with nuts could be provided in the pipe section (10), since this can be engaged from its ends. This detachable connection of the pipe section (10) on the one hand with the two fitting parts (14 and 16) is conceivable for the case in which the entire fitting is to be made of metal instead of plastic.

The other embodiments of the fitting according to the invention have in common that, like the preferred embodiment, they each have two U-shaped grooves 126, 226 and 326, the flanks of which are formed by two parallel flange strips 128, 228 and 328. In these other embodiments, the bottom of the groove is now also formed by a flange strip 132, 232 or 332 which forms the inner groove wall and is arranged perpendicular to the groove flanks and which in the fourth embodiment according to FIG. 7 is fastened only on one side to one of the two parallel flange strips 328, while in the second and third embodiment according to FIGS. 4/5 and 6, these groove flanks are connected.
The two mutually closer groove flank flange strips 128, 228 or 328, which form the inside angle of the fitting, are on their two parallel edges 134, 234 and 334, on which the two groove base flange strips 132, 232 and 332 join, by means of a movable flange strip 136, 236 and 336 jointly common to the two mirror-image fitting halves, in that this movable flange strip consists of soft PVC, while the rest of the rest is made of hard PVC. The movable flange bar could also be made of hard PVC if it is hinged to the butt edges by means of two film hinges (weak point joints).
Except in the third embodiment, in the other embodiments, the cavity 138, 238 and 338, which is delimited by the two groove base flange strips 132, 232 and 332 and the movable flange strip 136, 236 and 336, is provided with a filler body, namely with a circular cylindrical fitting part, namely a pipe section 110 or 310, the outside diameter of which is adapted to the desired inside fitting angle such that the pipe section is affected by the two groove base flange strips 132 or 332 and by two additional groove-parallel, rigid flange strips 140 or 340, which each lie in a vertical plane with the groove flank flange strips 128 and 328 continued by them and give each fitting half an H-shaped profile, regardless of the movable flange strip 136 or 336.

According to FIG. 6, the third embodiment also has two rigid flange strips 240, which, however, are curved instead of just a circular arc and overlap one another even with a right fitting internal angle, and they continuously merge into the molded-on groove flank flange strips 228. The common cylinder axis of both flange strips 240 is the pivot axis 242 of the fitting, which coincides with the intersection of the planes of the groove base flange strips 232. Of course, this only applies approximately.

In the fourth embodiment, according to FIG. 7, there is twice an independent unit consisting of the groove flank flange bar 328 which is not articulated on the movable flange bar 336 and the coplanar connecting rigid flange bar 340 and a fir-tree-like pin 344 which projects vertically inwards and into one of of the groove base flange strip 332 and a parallel additional flange strip 346 formed flat space 348 engages positively and elastically in a form-dependent manner, to an extent dependent on the width of the grooves 326, so that a to the width of the skirting board ends to be connected (in FIG. 7 indicated) adapted detachable connection of the two groove flank flange strips 328 exists. This connection serves as a stop when the rigid flange strip 340 strikes the pipe section 310, which is now affected by the two additional flange strips 346 instead of the groove base flange strips 332.
