Description

A FRAME SECTION FOR THE BORDERING OF A PLATE-SHAPED PANEL This invention relates to a frame section for the bordering of a plate-shaped panel, in which respect the frame section comprises an angular section part and a likewise angular ledge, the frame section as a whole being substantially U-shaped in cross-section.

The panel, consisting for example of a glass plate, can thereby be pressed with an edge strip inbetween one limb of the angular section part and the ledge, whilst one lsbof the angular section part lies opposite an end face of the panel. In order to connect the ledge in an appropriate manner to the angular section part, provided in a part of that limb of the angular section part which protrudes laterally therefrom and which lies opposite the end face of the panel is an undercut groove in which can be fixed fastening means of the ledge.

In the case of the generally known frame sections of this type, the fastening of the ledge is effected in that this is hooked or jammed directly with an angled edge strip into the undercut groove in the relevant limb of the angular section part. The stability of this fastening depends substantially upon the fact that the plateshaped panel exerts a uniform counter-pressure on the ledge and the ledge itself has an adequate inherent stiffness in order to withstand the compressive stress.

Upon the occurrence of pressure waves, however, the ledge experiences an alternating stress, by initially being relieved of the counter-pressure of the panel, whereby it loses an adequate hold in the groove of the section part, in order then to be shot out of the groove as a result of a recoil effect of the panel. The known frame sections of this kind are therefore unsuitable for glazings and similar plate-shaped panels if these are exposed to the danger of pressure waves.

The problem underlying the invention is to improve a frame section of the type described at the beginning hereof in such a way that the fastening between the angular section part and the ledge which supplements this in a U-shaped manner also withstands considerable stresses by reason of pressure waves acting against the plate-shaped panel.

To solve this problem the present invention provides a frame section for the bordering of a plate-shaped panel, comprising an angular section part to which can be fastened a ledge which supplements said part in U-shaped manner, whereby the panel can be pressed with an edge strip inbetween one limb of the angular section part and the ledge, whilst one limb of the angular section part lies opposite an end face of the panel, in which respect provided in a part of this limb which protrudes laterally beyond the panel is an undercut groove into which can be fixed fastening means of the likewise substantially angular ledge, characterised in that the fastening means of the ledge consist of at least two fillers which are arranged coaxially with one another in the longitudinal direction of the angular section part and parallel side-byside in the transverse direction of the angular section part, in which respect the fillers arranged respectively side-by-side jointly over at least a part of their length fill up the undercut groove.

The fillers can be inserted with considerable play successively into the undercut groove in that part of the limb which protrudes laterally beyond the panel and be arranged along with complete abandonment of the play in pairs in the transverse direction parallel side-by-side, in which respect the pair of fillers completely fills up in parts the undercut groove. After the insertions of the plate-shaped panel, in this way numerous pairs of fillers can be fixed as required in the undercut groove of the angular section part and form by their combination not only secure fastening means for the ledge which supplements the angular section part in a U-shaped manner and which can, for example, be clipped onto the fillers, but stiffen, depending on the arrangement density of the fillers, the ledge in a very effective manner.In many cases, however, it is also sufficient if, per limb of a frame, merely two pairs of fillers are associated with the relevant frame section, of which then preferably. one pair of fillers each is arranged in the vicinity of the end of the limb.

In accordance with one proposal of the invention, the fillers which are respectively arranged side-by-side mesh with each other on their mutually facing sides in the transverse direction of the angular section part in force- and form-locking manner.

As a result of this meshing, which in accordance with a further proposal of the invention can come about in a particularly advantageous manner in that the fillers of one row have respectively at least one dovetailed groove and the fillers of an adjacent row have respectively at least one dovetailed tongue, the groove and the tongue being on mutually facing sides, the pairs of fillers in the solely stressed direction perpendicular to the panel plane behave like anchorages, formed in one piece, of the ledge which supplements the angular section part in a U-shaped manner and which acts for example as a glass retaining ledge.

In accordance with a further proposal of the invention, also fillers of one row can respectively overlap two fillers of the adjacent row, so that the two rows of fillers form a stable retaining rail or support bar for the ledge.

The retaining rail formed in this way C extend over the length of the frame section save fr residual amount. The length of the residual amount is determined by the length of the fillers which are to be introduced lastly into the groove, so that these fillers can still be introduced side-by-side with play in the longitudinal direction of the groove.

The fillers can, however, also be arranged distributed uniformly over the full length of a frame section if, in accordance with a further proposal of the invention, fillers of one row are spaced from one another. In this case, first of all the necessary number of fillers is introduced in close sequence into the groove and then distributed by appropriate axial displacement over the length of the section.

The secure hold of the fillers in the undercut groove of the angular section part can be additionally improved if, in accordance with yet a further proposal of the invention, the fillers on their sides remote from one another have respectively a groove, in which there engages a respective web, defining the aperture cross-section of the undercut groove, on the limb of the angular section part.

In order not to restrict the fixing of the fillers to the region of the undercut-groove, but also to utilise the plate-shaped panel itself for the stabilising, and more especially also to counteract a warping of the fillers perpendicularly to the plane of the plate-shaped panel, a further proposal of the invention provides for the fact that integrally formed on the fillers of the row situated closest to the plate-shaped panel is a web which extends at least partially over the end facf of the panel.

Between the web integrally formed on the fillers and the end face of the plate-shaped panel there can be arranged pressure blocks made of wood, plastics material or the like, so that these are supported on the one hand directly against the end face of the panel and on the other hand against the integrally-formed web, by way of which the fillers connected in form-locking manner to one another are additionally held.

For the secure and reliable fastening of the ledge on the fillers, the fillers of one row can form, with the fillers of an adjacent row, a groove which is open towards the panel, in which groove can be clipped a nose of a web which is integrally formed laterally on a limb, directed perpendicularly to the panel, of the ledge.

In the case of this proposal of the invention, the exact fitting shape of the ledge can remain restricted substantially solely to the fillers of the row, against which the inside of the ledge exclusively comes into abutment.

In order, however, directly to engage all fillers of the ledge, another proposal of the invention provides for the fact that the fillers of the row situated closest to the panel have a groove which is open towards the panel and in which there can be clipped a nose of a web which is integrally formed laterally on a limb, directed perpendicularly to the panel, of the ledge. In this case, side parts of the fillers of both rows come into abutment against the inside of the ledge, in which respect, however, the nose of the web of the ledge engages into a groove of the fillers which lie closest to the plateshaped panel. In this way also the ledge itself assists the holding-together of fillers arranged parallel side-by-side.

Finally, a further proposal of the invention addtionally provides for the fact that fillers arranged parallel side-by-side are bolted, or screwed, or rivetted, or glued together.

As a result of this additional connection of the fillers which are arranged parallel side-by-side, also a mutual displacement of the fillers after their proper positioning in the longitudinal direction of the profile is precluded. With this proposal unauthorised removal of the ledge can more particularly be prevented and also that thereupon fillers are axially so displaced that they can likewise be removed successively from the undercut groove.

It naturally also lies within the scope of this invention to provide the fillers on their mutually facing sides with recesses such that these define a cylindrical free space, into which can be driven a tapered pin or a notched pin or the like, which holds the fillers in press fit within the groove in the intended position. It equally lies within the scope of this invention to screw at the ends of the frame limbs formed from the frame section threaded bolts or the like in such a way coaxially into the limbs that any displacement of the fillers is precluded. In the closure position of a frame formed from the frame section in accordance with the invention, consequently the positions of the fillers cannot be manipulated.

The invention will be described further, by way of example, with reference to the accompanying drawings in which each of the five figures is a cross-section of a different preferred embodiment of the frame section of the invention.

In all the exemplified embodiments the frame section consists of a congruously fashioned angular profile or section part 1 of which a limb 2 butts laterally by way of an elastic sealing strip 3 against the edge region of a panel 4. Over the end face of the panel 4 there engages a limb 5 of the section 1, which is composed in the conventional manner of box section which are connected together by way of heat-insulating webs. Provided in a part of the limb 5 which protrudes laterally beyond the panel 4 is a groove 6 which is undercut in a hammerhead-shaped manner in cross-section and the aperture cross-section of which is defined by webs 7 and 8.

The angular section part 1 is supplemented in Ushaped manner by a likewise angular ledge 11, 21, 31, 41, 51 in such a manner that an elastic sealing strip 9, lying opposite the elastic sealing strip 3, can likewise be pressed laterally against the edge strip of the panel 4.

As shown in Fig. 1, the angular ledge 11 is connected, by fillers 12 and 13 arranged in pairs side-byside in the transverse direction of the section part 1, to the limb 5 of the section part 1. By reason of the particular cross-sectional representation of Fig. 1, only one pair of the fillers 12 and 13 can be seen, the rest being distributed over the length of the frame section.

The fillers 12 and 13 assume the cross-section of the groove 6 and are so fashioned on their mutually facing sides that they mesh into one another in forceand form-locking manner. For this purpose, the filller 12 has a dovetailed tongue 14 and the filler 13 has a correspondingly fashioned dovetailed groove 15. Additionally, after their placing the fillers 12 and 13 are connected unreleasably to one another by a POP-rivet 16. Driven into a cylindrical free space between the fillers 12 and 13 is a notched pin 17, by which the fillers 12 and 13 are held in press fit in the groove 6.

A web 18 integrally formed laterally on the filler 12 protrudes over part of the end face of the panel 4, which panel 4 is supported by way of a pressure block 19 on the web 18. Upper edge strips of the fillers 12 and 13 form jointly a channel or groove in which a nose 10 of the angular ledge 11 can be clipped.

As shown in Fig. 2, the angular ledge 21 is similarly connected, by fillers 22 and 23 arranged in pairs sideby-side in the transverse direction of the section part 1, to the limb 5 of the section part 1. The fillers 22 and 23 in turn occupy the cross-section of the groove 6 and are so fashioned on their mutually facing sides that they mesh into one another in force- and form-locking manner. The fillers 22 and 23 are each provided with a dovetailed tongue 24 or 24' respectively and a corresponding dovetailed groove 26 or 26' respectively. A web 28 integrally formed laterally on the filler 22 protrudes over part of the end face of the panel 4, which panel is supported on the web 28 by way of a pressure block (not shown). On its side remote from the panel 4 the filler 23 is provided with a groove in which a nose 27 of the angular ledge 21 is accommodated.The upper edge strip of the filler 22 has a groove in which a nose 20 of the angular ledge 21 can be clipped.

As shown in Fig. 3,~the angular ledge 31 is connected to the limb 5 of the section part 1 by fillers 32 and 33 which are arranged side-by-side in pairs in the transverse direction of the section part 1. In the case of this exemplified embodiment, too, the fillers 32 and 33 occupy the cross-section of the groove 6 and are so fashioned on their mutually facing sides that they mesh into one another in force- and form-locking manner.

The fillers 32 and 33 are# likewise provided each with a dovetailed tongue 32 or 34' respectively and a corresponding dovetailed groove 36 or 36' respectively.

A web 38 integrally formed laterally on the filler 32 protrudes over part of the end face of the panel 4, which panel 4 is supported on the web 38 by way of a pressure block (not shown). The upper edge of the filler 32 has a groove in which a nose 30 of the angular ledge 31 can be clipped.

As shown in Fig. 4, the angular ledge 41 is connected to the limb 5 of the section part 1 by fillers 42 and 43. The fillers 42 and 43 here too occupy the cross-section of the groove 6 and are so fashioned on their mutually facing sides that they mesh with one another in force- and form-locking manner. In the case of this exemplified embodiment, the filler 42 engages the filler 43, in which respect an edge strip of the filler 43 has a dovetailed tongue 44 insertable into a correspondingly fashioned dovetailed groove 46 of the filler 42. A web 48 integrally formed on the filler 42 protrudes over part of the end face of the panel 4, which panel 4 is supported on the web 48 by way of a pressure block (not shown). On its side remote from the panel 4 the filler 42 is provided with a groove in which a nose 47 of the angular ledge 41 is accommodated.Moreover, the upper edge strip of the filler 42 is provided with a groove in which a nose 40 of the angular ledge 41 can be clipped.

As shown in Fig. 5, the angular ledge 51 is supplemented in a U-shaped manner and is connected to the limb 5 of the section part 1 by fillers 52 and 53 arranged side-by-side. In the case of this exemplified embodiment, the fillers 52 and 53 occupy the crosssection of the groove 6, and a web 58 integrally formed on the filler 52 protrudes beyond part of the end face of the Dnncl 4, whici pinch 4 is supported on tho web 58 by way of a pressure block (not shown). In the upper region of the fillers 52 and 53 these are given their force- and form-locking by the ledge 51 an additional central web 54 of which depends into a recess 55 defined by the fillers 52 and 53. The ledge 51 supplemented in a U-shaped manner and subdivided by the central web 54 is pushed parallel to the plane of the panel 4 over the fillers 52 and 53 fixed in the groove and engages in so doing by a nose 57 into a lateral recess 56 of the filler 53.
