BRIEF SUMMARY
TECHNICAL FIELD
The invention concerns a device for hanging panels from load-beating structures in concealed manner and consisting of two bent metal parts affixed to the panels, and further it concerns a method for locking in positive manner this device to the panel.
STATE OF THE ART
As regards the visible fastening of panels to load-beating structures, it is known to enclose said panels in U-channels themselves affixed to the load-bearing structure. These U-channels incur the drawback they will not accommodate the thickness tolerances entailed by manufacturing. "Undersized" panels (i.e. too thin) relative to the nominal thickness shall only sit loosely inside the channel, whereas "thicker" panels can be inserted only by bending the channel while ruining the panel surface. Moreover the panels only can be gripped at their edges, and frequently this is inadequate when affixing large-area panels. In addition, half the U-channel always is visible from the outside.
In order to achieve masked affixing of panels to load-beating structures, U channels may be affixed to said structures by entering channels milled into the panel edge. The channels are parallel to the plane of the panel and are half the panel-thickness deep. As a result the panel thickness available for mechanical strength is reduced to less than half. Accordingly this method only allows mounting in masked manner panels no more than a certain size to load-beating structures.
DESCRIPTION OF THE INVENTION
The object of the invention is to create a device for affixing panels of various thicknesses and various formats in masked manner.
The problem basic to the invention is solved in that a U-shaped bent metal part 1, 1' is juxtaposed with an angle metal part 2, 2' so as to be mutually displaceable in the direction of the legs, both metal parts evincing obliquely bent end zones at one end which by entering two channels milled into the panel thereby positively lock into it. Advantageously lateral guide sections are present at one of the level leg zones of one of the two metal parts to receive the other metal part in displaceable manner. Furthermore, the two metal parts can be advantageously adjusted relative to each other by means of an adjustment screw.
In one advantageous embodiment of the device of the invention, the end zones of the bent metal parts subtend an angle of 45.degree. to 80.degree. with the panel plane and are mutually converging.
In another advantageous embodiment mode of the invention, the end zones of the bent metal parts are mutually diverging.
The invention moreover relates to a method to positively lock the device of the invention onto the panel. This method is characterized in that the channels are machined into the panel surface at an angle matching one of the angled end zones of the bent metal parts and by inserting and affixing the oblique end zones. The milled depth amounts to 50 to 95%, preferably 75 to 85% of the panel thickness and the sidewalls of the channels advantageously are milled to be arcuate. Also, a chamfered milling base is introduced when making the channels.
In a last and advantageous embodiment mode of the invention, milling is carried out by a manual milling machine displaceable in a milling guide and adjustable in a milling jig about a shaft at various angular positions relative to the panel surface.
DESCRIPTION OF THE FIGURES
The invention is elucidated below in relation to FIGS. 1 through 10 and in two advantageous embodiment modes for affixing the devices of the invention in positive manner.
FIG. 1 shows the elevation of the device of the invention, the part 2b of the right-angled metal part 2 resting against the panel, the angled end zones 6, 7, a guide channel 4, the U-channel metal part 1 and the adjustment screw 3 also being shown.
FIG. 2 shows a top view of the device of the invention along arrow II of FIG. 1.
FIG. 3 is a side view of the device of FIG. 1, with the U-shaped metal part 1 and the right-angled metal part 2, which rest against each other by their legs 1a, 2a and which are mutually
