Method for assembling workpieces along a common support surface and fittings for fastening a plate for performing this procedure.

The invention relates to a composite assembly of workpieces with two common support surfaces, and in particular workpieces, which have different expansion coefficients. It can be used with advantage for fastening of parts made of plastic material and in particular of metal on plates or fields from a brittle Material like glass, which is difficult to work with, slips and is not very suitable for gluing processes. According to the invention the usual fixings should be completed by an anchorage through which each. Sliding of the parts is avoided. It is particularly advantageous for attaching fittings such as frames, Locks or door hinges.

A preferred field of application is that of glass doors. It is known that, for example, the hinge hinges the-

these doors are generally mounted by simply clamping two boards by means of bolts that go transversely through cutouts in this plate or this field. This method requires strict clamping and thus deep cuts _t should be prevented when in that the washer slides in the mountings.

Has also been proposed to glue these parts or workpieces or to combine the "two types of attachment, thereby obtaining the sliding operations eliminated at the same time the cuts could be reduced or you could even do without them; adhesives which are suitable for this use, are very stable or solid, in the heat-curing adhesive, in general, epoxy resin-based.

Unfortunately, the connection is the seat of considerable stresses, capable of tearing the glass out of the tapes of the glued surface under the action of complex stresses caused by the combined shear and bending forces and the polymerisation shrinkage of the resin and due to the weight of the Disc, due to misalignment and bumps and finally due to different coefficients of expansion between the carrier, resin and mounting board.

In particular , it is known that it is generally difficult to properly secure the elements of a hinge so that the axes of the fixed parts and the movable parts of the pivot are precisely aligned with one another and can be nested within one another from the first attempt.

409847/0346

Even in other cases where it is a question of installing fixed panes or plates, you can Observe considerable forces, which are due in particular to the! temperature differences. Such Panels are often placed on the outside of buildings and are exposed to temperatures that can vary from - 30 "to + 60 ° C. Due to the differences in the expansion coefficients between glazing and Beams suffer a bend in the connections and are exposed to separation forces that are still able to lead to breaks.

This disadvantage is to be remedied according to the invention.

For this purpose, the invention is based on a method for fastening a (structural) part to a carrier and is characterized in that the assembly is carried out by means of mutually independent counter- ^{fastening pieces (plots d f} accrochage) that are glued to the carrier, the Part to be fastened comprises an organ which is supported on the respective narrow sides and is itself held in contact with the support surface by an auxiliary means such that only shear forces are exerted on the counterparts essentially parallel to the support surface, with the exception of any bending or tearing force .

The polymerization shrinkage or are also distributed the thermal expansion more uniform across' the counterparts and no longer cause bending forces at the level of the connection. The shear strength achieved is by far greater than if the connection had been equipped in the most complex way, such that it

409847 / 03-4.8

2420123

with a reduced space requirement, a sufficient support surface to absorb the stresses to be transmitted is achieved to obtain.

The counterparts are preferably cylindrical with a circular base, in particular for the sake of simplicity educated. It is advantageous to use one-piece counterparts that can easily be made with the help of a Adhesive resin of the same kind as the aforementioned adhesives are formed. Their diameter can range from 5 to 10. mm vary, for example, their thickness between 3 and 6 mm.

In order to form them on one side or the other of the carrier, it is advantageous to use a plate as the shape made of polytetrafluoroethylene with holes of a shape complementary to that of the counterparts and, after this form is attached to the carrier, herein

potting the adhesive resin; the counterparts are removed from the mold as soon as they have reached the desired strength and adhere intimately to the support surface.

An adhesive material particularly useful in accordance with the invention to form the counterparts is useful, consists of an epoxy resin, the barium sulfate and colloidal Having SiliciunöLöxyd as a filler. These fillers are used to reduce the shrinkage during polymerization and the expansion coefficient of the resin and lead to a favorable thixotropy.

The invention is applicable to the fastening of parts on any carrier in which gluing, in particular

- 5 409847/0346

on materials such as glass, ceramics or even cement is possible and is particularly advantageous when fastening parts with a coefficient of expansion higher than that of the carrier, in particular for components made of light metal alloys on glass plates or panes.

The invention also relates to fittings which are designed in such a way that they can be operated according to this method can be attached, and in particular fittings such as hinged hinges that are glued to glass plates Wear mating contact pieces, are attached; these fittings are characterized by their presence a fastening device with an organ with bearings, which are used to accommodate the mating contact pieces are intended, an organ, which can consist of a circuit board, which directly on the mating contact pieces is set and is provided with a tensioning device.

The counterpart fastening device is preferably assigned to a joint bearing perpendicular to the plate, which prevents the load from transferring torsional stresses to the adhesive zone and is preferred this joint training itself assigned to a second joint training, which with the first a cardan suspension forms.

The organ provided with Lageimgen can consist of a plate which is placed directly on the contact pieces and in place by clamping on a counter plate is held; in particular, you can use a screwed counter plate or, if it is arranged on an edge,

- 6 409847/0346

- 6 net is a dovetail mount.

Haeh another embodiment of the invention can the fitting simply comprise a perforated board to be plugged onto the counterparts, which is otherwise on the glass plate by means of an adhesive, which has a modulus of elasticity smaller than that of the counterparts, is glued. It is possible to use a polysulfide adhesive or even use a simple good quality neoprene adhesive, with the adhesive function consists in keeping the hardware in contact with the surface of the glazing, and the Transmission of the tangential forces is always ensured by the counterparts.

The fitting can also have an intermediate fastening plate that is indirectly attached to the plate through the boards itself is determined.

A particular embodiment consists of a hinge whose Xürangelband comprises three parts, namely an arrangement with two semi-axes perpendicular to the plane of the disc or field; a knot joint that is so designed is that it pivots on a fixed part, hinge or preferably half hinge, which is fixed connected to the orbits; and a part or interconnection arrangement that makes this knot joint allows to rotate about an axis perpendicular to the previous two.

Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings are explained in which:

409847/0346

Pig. 1 is an exploded perspective view Representation of a hinge fastening device according to the invention shows is intended in particular for wings of increased weight;

Pig. 2 shows a partial section along the line II - II in Pig. I;

Pig. 5 shows a perspective illustration

the parts of another door hinge, also according to the invention; and the

Pig. 4 to 6 show three complementary representations with partial sections along the lines IY - IV, V-V and VI - VI of a hinge, its Hinge of a variant to that of the Pig. 3 corresponds.

According to the Pig. 1 and 2 comprises a pane of glass or a glazing 1 (on which the device according to the invention is to be attached) in the vicinity of a vertical edge 2 and on both sides a plurality of cylindrical contact pieces 3 made of solid adhesive resin such as ABATrT) ITE, which by ( Press) forms with the help of a Porm made of polytetrafluoroethylene deposited and then polymerized or made of an epoxy resin with two components from MINNESOTA, with IO i> powdered barium sulfate and 5% colloidal silicon dioxide "Aerosil" was deposited as filler. After polymerization of the adhesive material the porm is pulled out and the surface of the mating contact pieces is ground flat using an abrasive.

409847/0346

According to the example shown, the ß-mating contact pieces each surface regularly arranged inside a regular hexagon.

The actual hinge fastener "consists from a pivot bearing 4 of bow shape with two essentially parallel plates or jaws 5 » the distance of which is slightly greater than the thickness of the glazing that they must accommodate, and each of them Carry a fairly deep recess 6 to allow the "passage of the contact pieces during assembly. The two boards are connected by a narrow piece 7 through which a bearing 8 pierces is and on which a substantially semicircular support 9 is provided. The two boards have circular symmetrical recesses Io, 11, the axis of which is perpendicular to that of the disc, and are of a diameter at least equal to that of the circle formed for that formed by the Zontakt pieces Hexagon is to be circumscribed. In these recesses, axially, smoothly sliding, perforated disks 12, 13 of a diameter corresponding to that of the recesses are slidably inserted. The perforations 14 of the Discs are arranged in the same way as that of the shapes of the contact pieces 3 so that if the glazing or pane 1 is slidably inserted between the plates 5 of the bracket, the contact pieces face the recesses, the discs sit exactly on the mating contact pieces 3. As Clearly Fig. 2 can be seen, the discs have a sufficient thickness that they, when they are at their Place that go beyond the recesses on the inside and thus prevent the door hinge from pulling through

- 9 - 409847/0346

to be pulled out in the plane of the glazing.

Each disc is in its respective storage, for example by means of a Seeger ring or a Locking plate 15 held, which carries on the inside a flat ring 16, which in is able to be introduced into the corresponding recess. The plate is with the outer surface the corresponding board set by means of screws 17 .. The remaining between the discs Games, the recesses and the platelets allow the pivot bearing with respect to the discs around the to pivot the latter common axis 18, whereby it is vemLeden that the counterparts one Shear moment are exposed.

The knot joint 19 of the lürangelband is rotatable on the pivot bearing 4 with the aid of a cap or a low friction joint mounted so that it is about an axis 20 parallel to the plane of the glazing and can rotate perpendicular to the edge 2. For this purpose, it comprises a plate 21, over the thickness of which is semicircular Recess 9 'is cut out, which sits on the semicircular support 9; also is a right-angled Displacement 7 * provided, starting with opiel the narrow piece 7 covers. The plate 21 thus forms a hinge cap or a hinge cover to the Support 9, the jaws 22 of which allow the return of the knuckle joint in a direction perpendicular to the plate impede. In addition, the knot joint is attached to the pivot bearing by means of an annular disk 23, the one hand in a hole 24- through the plate

is drilled, inserted, and on the other hand already is inserted into the bearing 8, the interior of which is held backwards by means of a screw 25, which in a thread 26 of the washer penetrates. The stand, not shown, on which the glazing is arranged is to be, carries a half hinge 27, to which the fishing rod is attached by means of a fitsche 28 is that allows the wing to pivot.

For the assembly, you first put the hinged door hinge together. For this purpose, the recess 9 ^{f of} the cap 21 is placed on the semicircular support 9 of the pivot bearing. The ring washer 23 is then inserted into the bore and the screw 25 is screwed into the thread 26 of the ring washer 23 from the inside. The glazing 1 is then slid between the plates 5 of the door hinge until the counterparts 3 are brought to the location of the recesses 10 and 11. The perforated panes 12 and 13 are finally inserted into their respective recesses and placed on the counterparts 3 of the two surfaces of the glazing. To block the discs in their bearings, the flat rings 16 are inserted into the recesses and the plates 15 are screwed onto the outer surfaces of the jaws 5 by means of screws 17. The plates are masked by decorative strips.

As soon as the assembly is finished, the! Eürangelband 4 can no longer be separated from the glazing. In contrast, the pivot bearing can rotate around the axis with respect to the disks and thus with respect to the counterparts turn. On the other hand, the knot joint 19 can move with respect to the pivot bearing about the axis 20 of the annular disk

- 11 409847/0346

turn. By rotating about the axes 18 and 20, the axis of the bore 29 of the knot joint can be changed Orientate yourself until they are in exact alignment with the axis 30 of the Buhrungen of the HaIbscharniers 27 is coming. Assembly of the hinge can expediently by turning the hinged door hinge these axes are oriented, Ms alignment with the door hinge is established. on the other hand These two axes form a curtain-type suspension, which only has visual powers on the perforated panes with the exception of every! the bending stresses in the plate or disk are also eliminated.

According to the Pig. 3 to 6 of the drawings, the glazing 31 can be one of the wings of a door or one Form windows from toughened glass. On each of the two intended to hold a fishing tape It is placed on both planes with a mounting plate 32, which can be rectangular, like Pig. 3 shows, but it can be circular, as FIG. 4 shows. This plate can glued directly to the glazing, but here it is still to get a more solid attachment, preferring to anchor them to the glazing by being content with placing them on their counterparts from ABAEDIiEE 33, which are fixed to the plate and which are in holes 34 analogous to the above penetrate described. There are four such mating contacts in Pig. 3 shown, three in the variant the pig. 4. Each of the plates 32 is provided with a pin 35 on the outside.

- 12 40 * 9847/0346

The fishing hinge has the usual shape of a bracket with two similar plates 36, which are firmly connected by a narrow piece 37 and carry an inotary joint 38, the bore 39 of which is intended to accommodate the axis of the hinge. Each of the two plates has a rectangular bearing 40 on the inside, which is delimited on the one hand by the narrow piece 37 and on the other hand by three narrow handles 4-I ₅ 42 and 43. In the embodiment of Mg. 3, the edges 41 and 42 are continuous. The fishing tape is mounted on the two mounting plates via two rectangular arched Eeder leaves 44, which are in place in S ¹ Ig. 4 are shown. The two sheets have a hole 35S in the middle which is intended to receive the pin 35 and their two longitudinal edges 41 '42 ^! sit in each of the bearings 40 along the inner bearing surface of the two longitudinal edges 41 and 42. The width of each sheet 44 is slightly larger than its bearing,

in
such that they are arched / held in a direction perpendicular to the axis of the hinge. They each rest against the corresponding fastening plate 32 along a generating line 45 parallel to the longitudinal edges 41 'and 42' and tension them elastically between them

The thickness of the edges 41, 42, 43 is at least equal to that of the Eeder leaves 44 and the distance which if it separates, it must allow the glazing to pass with play. At least one of the elements must also allow the passage of the plate 32 on each side: in the examples shown it is each of the two edges 41 and 42.

The assembly of the fishing tape is then very easy.

409847/0346

One can put each of the spring leaves 44 on the pin 35 of one of the mounting plates 32 and then insert a fishing strap sliding against it along the edge of the glazing; the spring leaves thus penetrate under each of the plates 36 through the slot made, for example, between the disc 31 and the edge 4L. They come into abutment against the inner bearing of the edge part 42 and it is sufficient to bring them into the interior of the bearing 40 with the aid of suitable pliers with the application of force in order to enclose them in the interior of this bearing. It is still preferable before the I ^l ederblätter44 to arrange inside the fishing tape and then press it against the plates 32nd The leaves are then sunk to allow the pegs 35 to pass; then the latter sit in the holes 35 'and the spring leaves return to their position.

The dismantling is done with the help of a tool which is placed under the spring leaf 44 between the glazing and every hinge is led; this can only be done if it becomes possible simultaneously to have access to both sides or surfaces, d. i.e. when the door or window is open.

Finally, it is advantageous to provide the two edge parts 41 and 42 with cutouts, as shown in FIG 46 (Figs. 4-6) are shown, thereby facilitating this operation. Otherwise they do it possible to put a decorative strip on the boards by grasping them on their side surfaces.

Here, too, the fishing tape points to the disc

- 14 409847/0346

two degrees of efficiency. Between the leaves of each leather 44 and the plate 32 there is namely a first pivot bearing - perpendicular to the plane of the notes that is obtained by rotating the plates about the axis 47 of the two pins 35. Due to an between the edge parts of the plating and the disc existing However, there is also a second pivot bearing about an axis 48 perpendicular to the pivot pin at the same time and to the previous axis. Namely, the rotations that are necessary to align the various Parts of the hinge are very small and allow the hinge to go by a moment applied about axes parallel to the axis 48, the two spring leaves 44 deform slightly due to their elasticity by being insubstantial on the plate 32 perpendicular to their producing contact roll off like Pig. 4 shows. This allows the fishing line to move several degrees about axis 48 turn. A device equivalent to that described above is thus obtained.

However, it is also possible within the scope of the invention to make other modifications such as, for example to replace the leaf springs 44 with wedges, which also have a cylindrical bearing surface, the are inserted with the plate 32 through a slot, which is worked out in the edge part 41 and which with its lower edges against the edge part 42 come to rest, with their flat surface on the bottom of the bearings 40 with the interposition of a resilient covering rests, which holds them in contact with the mounting plates 32. It should also be noted be that in the case of a wing, which on the basis of two fishing tapes around a vertical axis

- 15 409847/0346

pivoted, the belonging to the lower hinge Plates 32 too, provided that the pivot axes 59 form a hinge on the plate or Seheibe cannot be attached.

The devices described "free the bond Sound of any stress caused by a palsch alignment the pivot axes could be caused. In addition, the attachment with anchoring leaves over Counterparts the stresses in! Omission come, caused by the shrinkage or shrinkage in the usual joints in which adhesives be used with high strength; also. will Stresses due to changes in temperature reduced to a minimum.

By the measure according to the invention, fittings on disks cxfer plates and in particular Ingelbands on glass sashes under favorable conditions in terms of strength and ease of arrangement and design.
