Insulating Body for Multi-Shell Construction Elements

Abstract

An insulating body for multi-shell construction elements for spacing apart and thermally separating at least two profiled section elements relative to each other has a base member with a first side and a second side opposite the first side. Fastening projections are arranged on the first and second sides of the base member and secure the insulating body in receptacles of the profiled section elements. At least the first side has two of the fastening projections. The base member has a hollow chamber with an inner guiding contour for receiving and guiding fitting parts. A multi-shell construction element with at least two profiled section elements is provided with at least one such insulating body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] FIGS. 1a and 1b show an embodiment of an insulating body 1 according to the invention that connects two profiled section elements 2, 3 but also separates them thermally and keeps them spaced apart. The illustrated insulating body 1 is comprised substantially of a monolithic base member with two insulating stays 4 and a transverse stay 5, wherein the insulating stays 4 are extending from the profiled section element 2 to the other profiled section element 3 and are connected transverse to the main extension direction R of the insulating stays 4 by the transverse stay 5. Together, the insulating stays 4 and the transverse stay 5 define a hollow chamber 6 which comprises an inner guiding contour 7. The latter is designed due to its shape for receiving and guiding fitting parts, as will be explained in the following by means of FIGS. 3 and 5 to 7.

[0028] The insulating body 1 has on opposite sides, i.e., each side facing one of the two profiled section elements 2, 3, respectively, two fastening projections 8 which are formed as outwardly widening fastening legs and engage receptacles 9 of the profiled section elements 2, 3. The fastening projections 8 are fixedly connected in practice in that pressure is applied to the exterior sides 11 of the receptacles 9 and cause deformation so that the exterior sides 11 contact tightly the fastening projections 8 and secure them such that they are non-slidable. This method is referred to as curling.

[0029] In addition, the insulating body 1 comprises a guiding stay 12 which is guided in a matching guiding receptacle 13 of the profiled section element 2 so as to be slidable but captively secured. For this purpose, the illustrated embodiment with a T-shaped guiding stay 12 and a substantially C-shaped guiding receptacle 13 are beneficial. Positioning of the guiding stay 12 between the fastening projections 8 and selecting its length so as to be reduced relative to the fastening projections 8 has the advantage that during curling of the fastening projections 8 pressure is not indirectly applied to the guiding receptacle 13 so that the sliding action of the guiding stay 12 is maintained. In areas in which, for example, by thermal action, the profiled section element 2 is deformed relative to the profiled section element 3, the non-slidable connection of the insulating body 1 can be released in such an embodiment from the profiled section element 2 in that the connection of the fastening projections 8 is separated from the remaining part of the insulating body 1, for example, at the position that is indicated in FIG. 2b with reference numeral 18. The guiding stay 12 continues to reliably secure in this context the profiled section element 2 on the profiled section element 3 but so as to be slidable perpendicular to the drawing plane.

[0030] The insulating body 1 illustrated in FIGS. 1a-1b and 2a-2b have in addition outwardly open receptacles 14, 15 into which additional functional elements can be inserted. For example, rubber seals, fasteners or further fittings can be received therein. While the hollow chamber 6 of the insulating body 1 is configured open toward the profiled section element 3 (FIGS. 1a, 1b), the insulating body 1 of FIGS. 2a, 2b has a closed hollow chamber. This is possible due to the extended embodiment of the insulating body 1 as shown in FIGS. 2a-2b which is provided for thicker construction elements. In FIGS. 2a, 2b, the entire guiding contour 7 is thus formed by the wall of the hollow chamber 6 while in FIGS. 1a, 1b a guiding contour area 17 of the profiled section element 3 of a circular circumference segment shape takes on this partial task.

[0031] Both embodiments of the insulating body (FIGS. 1a, 1b; 2a, 2b) have recesses 19 in the guiding contour 7. They serve preferably for receiving sheet metal nuts, blind rivets, countersunk rivets or similar fastening means and are so deep that the fastening element received therein does not project past an imaginary extension of the guiding contour 7. Advantageously, the outwardly open receptacles 14 and optionally 15 as well as the recesses 19 along the insulating stays 4 are arranged alternatingly so that the stay material is not reduced improperly at any position. By appropriate proper positioning, the insulating body 1 can thus be embodied with minimal material use and therefore can be designed to be accordingly lightweight but still stable.

[0032] FIGS. 3-7 show embodiments of multi-shell construction elements employing the afore described insulating body 1. In FIG. 3, two glass panels that are connected by a hinge 21 are shown. The profiled section elements 2, 3 support here double pane glazing 22. Thermally, the profiled sections 2, 3 are separated from each other by the insulating body 1. The glass panel to the right in the illustration is also lockable by means of a grip 23 which acts on a locking pin 24 and can cause it to slide in a direction perpendicular to the drawing plane. The locking pin 24 is guided as a fitting in the hollow chamber 6 of the insulating body 1. In the embodiment according to FIG. 3, the guiding stay 12 does not serve for slidably guiding the insulating body 1 but supports the stay 12 only against the profiled section element 2.

[0033] FIG. 4 shows the upper left corner of a three-panel glass folding device as it is illustrated in the upper part of the Figure as a pictogram. FIGS. 4 through 6 serve only for illustrating how, for example, the locking pin 24 is acting in the construction element. It engages, as shown in FIGS. 5 and 6, in a part of an upper frame section 26. FIG. 7 ties in with FIGS. 1a, 1b to 3 and shows the insulating body 1 with the locking pin 24 guided therein similar to the illustration in FIG. 3. In the area of the frame section 26, the configuration of conventional insulating stays 27 can be seen also.
