Abstract:
For securing a fitting to any point of an extruded section by a clamping device, the extruded section has two spaced apart parallel webs between which a holding part of the fitting can be inserted which is supported on the edge faces of the webs facing one another. The holding part has support flanges which can contact the outer sides of the webs. The holding part is provided with at least one bore in which a pin carrying the clamping element is rotatably held such that as a result of its turning the clamping element engages at the inner sides of the webs and tensions the support flanges against the outer sides of the webs.

Description:
BACKGROUND OF THE INVENTION 
     The invention relates to an apparatus for securing a part, preferably a hinge part, to an extruded section by a clamping device. 
     The problem frequently exists of securing fittings to extruded sections, for example to connect extruded sections to one another or to secure further parts to the extruded sections by these. If extruded sections form the edges of, for example, body parts of a cupboard or a flap, hinge parts have to be secured to these for the hinging of doors or flaps. An extruded section is known from DE 297 14 874 U1 in the form of a hollow chamber section to which hinge cups of a hinge can be secured in that the hollow chamber section is provided with cut-outs corresponding to the contour of the hinge cup and that flanges of the hinge cup are clamped to edges of the cut-out by anchor discs which can be tensioned against the flanges by screws. 
     It is the object of the invention to provide an apparatus of the kind first named with which fittings can be secured to the extruded section at any point thereon in a simpler manner and without cut-outs thereon. 
     SUMMARY OF THE INVENTION 
     This object is solved in accordance with the invention with an apparatus of the kind first named in that the extruded section has two webs spaced apart and parallel from one another, between which a holding part of the fitting can be inserted which is supported on the end faces of the webs facing one another; in that the holding part has support flanges which can contact the outer side of the webs; and in that the holding part is provided with at least one bore in which a pin carrying a clamping element is held rotatably such that as a result of its turning the clamping element engages at the inner sides of the webs and tensions the support flanges against the outer sides of the webs. 
     The fitting in accordance with the invention can be secured at any point of an extruded section matched to this in the manner in accordance with the invention in that the holding part is inserted so far between the webs that its support flanges contact the outer sides of the webs. The fitting can then be clamped to any point of the extruded section in that the pin is turned so far by a tool that the clamping element, which lies between the webs on insertion, is turned so far that its flanged parts engage behind the webs and thereby effect a tensioning of the holding part with the webs or with the extruded section. 
     The webs expediently form the edges of a C-shaped section part of the extruded section. The webs can also be located at the ends of the limbs of a U-shaped section part of the extruded section. 
     The holding part can consist of an approximately rectangular block whose sides parallel to one another contact the end faces of the webs facing one another, with support flanges adjoining the sides of the block parallel to one another at both sides. 
     The support flanges can be formed by the side parts of a base board carrying the block. 
     In another aspect of the invention, it is provided that the pin is held rotatably, but axially non-displaceably in the bore and carries a wing-shaped bolt at its end passing through the bore, the arms of which bolt enter into their position engaging behind the webs from their position parallel to the webs by rotation of the pin. 
     The bolt preferably consists of a disc with chord-like sections parallel to one another whose section edges have a smaller spacing to one another than the end faces of the webs, with the longer parts of the disc projecting over the pin at both sides having a wedge-shaped or spiral torsion. This wedge-shaped or spiral torsion results in that the longer parts projecting over the pin first engage the webs in a contact-less or almost contact-less manner when the pin is turned and then engage at them in a tensioning manner as the turning increases so that a good and secure clamping of the fitting to the extruded section is ensured. 
     The pin can be provided with a polygonal, for example a triangular, continuation which passes through a complementary opening in the disc and is provided with a rivet head. A non-rotatable connection of the disc to the pin is ensured in this way. 
     The pin can be provided with a head which has a slot or a cross recess for the engagement of a screwdriver. 
     The head is expediently arranged in a recess and has a radial continuation which is rotatable between wall parts of the recess forming stops which bound an angle of rotation of approximately 90°. In this way, the clamping of the fitting to the extruded section can be effected by a rotation of the pin by approximately 90° without an incorrect mounting due to overturning needing to be feared. 
     The base board of the fitting can be provided with wall parts standing at right angles on it and at which two links of a double-link hinge are mounted. In this manner, the fitting is formed in the shape of a hinge cup of a double-link hinge. 
     The apparatus in accordance with the invention is suitable for the securing of any parts to an extruded section. 
     In accordance with a preferred embodiment, it is provided that the holding part or the base board carries a handle. This handle can serve, for example, the actuating of a door or of a flap of a piece of furniture. 
     The handle expediently consists of a substantially U-shaped bow whose limbs are connected to the holding part or to the base board. The limbs, adjoining the holding part or the base board, can be curved in a U shape from their common plane and enclose a web of the extruded section with their curves. In this way, a more solid connection of the handle to the holding part or to the base board is provided. 
     The apparatus in accordance with the invention is also suitable for the connection of extruded section parts to one another. In accordance with another preferred embodiment, it is provided that the clamping unit consists only of the holding part; that the holding part passes through the plane of the end faces of extruded sections to be connected abutting one another at an obtuse angle; and that the parts of the holding part disposed at both sides of the plane can in each case be tensioned in the adjoining C-shaped section parts by at least one pin carrying a clamping element. The extruded section parts to be connected to one another by the apparatus in accordance with the invention preferably have identical sections. The section parts can be connected to one another in a elongate form or also in a form standing at an angle to one another. The holding part can accordingly consist of an elongate section part or, however, also of an angular, preferably right-angled, section piece whose limbs have identical cross-sections. If extruded section parts are to be connected to one another at right angles, they are bevel cut. 
     In another aspect of the invention, it is provided that the section parts to be connected to one another are provided with hollow chambers which extend parallel to the webs and into which section pieces which pass through the plane can be inserted to stiffen the connection. The section pieces serving the stiffening can consist of flats which are provided with beading. To connect extruded section parts abutting one another at right angles, the section pieces are bent at right angles, with the limbs of the angle pieces being provided with beading at both sides of the bending point.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     A side wall  1  of, for example, the body part of a cupboard, can be seen from FIG.  1  and an extruded section  2  is connected to its edge. The extruded section  2 , made of aluminium for example, has a U-shaped section part  3  whose limbs are provided at their ends with inwardly directed bendings. This U-shaped section part encloses the edge of the wall  1  of the body part in a usual fashion. Adjoining the U-shaped section part  3 , the extruded section  2  is provided with another U-shaped section part whose web part  4  is formed by an extension of the outer limb  5  of the first U-shaped section part  3 . The upper limb of the second section part is formed by the web part  6  of the first section part and the lower limb  7  by a bending from the web part  4 . The limbs  6 ,  7  are provided with webs  8  which extend parallel to one another and whose end faces confront one another. The outer edges  9 ,  10  of the webs  8  form supports for the support flanges  11 ,  12  of a hinge cup  13  which is clamped to the extruded section  2 . The links  14 ,  15  which connect the hinge arm  16  to the hinge cup  13  are hinged to the hinge cup  13 . The hinge arm  16  is connected to a door or flap  17  in a usual fashion. The part  17  can naturally also be the side wall of a body part to which the door, for example a glass door  1 , enclosed by the extruded section  2  is hinged by the hinge  13 - 16 . 
     The lower limb  7  of the extruded section  2  is extended beyond the web  8  in the manner shown. 
     The hinge cup  13  consists of a base board  18  which is connected at its lower side to a substantially rectangular block  19 . The block  19  has narrow, long sides  20 ,  21  which are parallel to one another and whose spacing corresponds to the spacing of the end faces of the webs  8  confronting one another. At its upper side, the base board  18  is provided with two walls  22  which are parallel to one another and which, together with a rear wall  23  drawn high, bound a cup-shaped space approximately rectangular in cross-section with an open front wall, with the bearing bolts for the links  14 ,  15  being held in a usual manner at the side walls  22 . 
     The base board  8  is provided at both sides of the walls  22  in the region of the rectangular block  19  with bores in which the smooth shaft  24  of a pin  25  is rotatably held. The pin  25  is provided with a head  26  which has a cross-recess  27  for engagement for a screwdriver. The head  26  is in each case let into a recess of the upper side of the securing board  18 . Furthermore, the head  26  is provided with a radial continuation  28  for which side wall parts of the recess  29  form stops in a manner such that the head  26  can be turned through approximately 90° in the recess. 
     The pin  25  is provided at the outer end of its shaft part  24  with a continuation  30  which is triangular in cross-section and which passes through a complementary triangular orifice  31  of a disc  32 . The continuation  30  is riveted to the disc  32  for the non-rotatable securing of the disc  32  to the pin  25 . The disc  32  is provided with lateral chord-like ease-offs  33  which extend parallel to one another. Curved edges  34  of the disc  32  are located between these ease-offs  33 , are curved like arcs of a circle and are torsioned in wedge or spiral shape in the manner visible from  FIGS. 1 ,  3  and  5 . 
     For the purpose of mounting, the pins  25  are turned in the manner visible from the left hand sides of  FIGS. 5 and 6  such that the projecting wing-like edges  34  of the disc  32  in the longitudinal direction of the rectangular block  19  show. In this position, the radial projections  28  contact a side of the recess  29  forming a stop. In this shape, the hinge cups are inserted between the webs  8  in a manner such that the flange-like edges  11 ,  12  of the base board  18  are supported on the outer sides of the webs  8  or of their extensions. In this mounting position, the locking of the hinge cups to the extruded section  2  takes place in a manner such that the pins  25  are turned through approximately 90° by a screwdriver such that the projections  28  contact the oppositely disposed stops of the recesses  29  such as can be seen from the right hand sides of  FIGS. 5 and 6 . 
     The hinge cup  13  expediently consists in the usual manner of an injection moulded part made of metal. 
     The clamping of a handle to an extruded section using the securing apparatus in accordance with the invention can be seen from  FIGS. 10  to  12 . The handle  40  is connected to a base board  41  which, together with the block-like rail  42 , forms the holding part which is generally designed in the same way as the holding part  18 ,  19  in accordance with  FIGS. 1  to  6 . A board-like part  43 , which is curved in U shape and which runs out into side limbs  44  which carry the actual handle consisting of a rod  45 , is connected to the base board  41 . The part of the board  43  bent in a U shape encloses an upwardly projecting web  46  of the extruded section  2  in the manner visible from  FIG. 10  such that the handle is also supported at the extruded section  2  via the U-shaped curvature and the section web  46 . The clamping of the holding part  41 ,  42  takes place in the manner described with reference to  FIGS. 1  to  9  by the pin carrying the clamping element. 
     In the embodiment in accordance with  FIGS. 10  to  12 , a frame is formed from the extruded section pieces which encloses the board  47  of a door or of a flap. 
     The connection of extruded section pieces  50  bevel cut at right angles by the securing apparatus in accordance with the invention can be seen from  FIGS. 13  to  15 . The extruded section pieces connected to one another generally have a rectangular shape, with a groove  52  being provided at the inner side in the limb  51 . The flanks of said groove are provided at their insides with webs  53  extending parallel to one another which form clamping webs for clamping elements  54 . A groove  54 ′ is provided at the end face of the limb  51  into which, for example, a door board  55  of wood or glass is inserted. The other limb  56  is provided with a hollow chamber  57  into which an angle section  58  of steel is inserted to stiffen the connection which is provided with beading  63  on both sides of its curvature  59  in the shape of an arc of a circle. 
     To connect the two bevel cut extruded section pieces  50 , a right-angle holding part  60  is inserted into the groove  52  and has a stepped section in the manner visible from  FIGS. 14 and 15 , with the steps formed between the upper section part  61  and the lower section part  62  forming the supports on the webs  53 . The clamping at the webs  53  takes place in the manner described with respect to  FIGS. 1  to  9  by the pins carrying the clamping elements, with each limb in the embodiment shown being provided with two clamping elements even though a single one would be sufficient.
