[0076] FIG. 1 depicts a possible first embodiment of the modular system according to the invention for a multiple insulating glazing unit. The modular system depicted here has two components, namely a double glazing component 1 and a closure component 2 with closure sealing means (not shown), which can be arranged, for producing a triple insulating glazing unit, in the double glazing component 1 by sliding as indicated by the arrow. The double glazing component 1 comprises a first pane element 1.1 with a first pane sealing surface, a second pane element 1.2 with a second pane sealing surface, and a spacer arranged between the first pane sealing surface and the second pane sealing surface. The spacer is composed of a plurality of spacer struts 1.3, which enclose an insulating glass volume between the first pane element 1.1 and the second pane element 1.2 and are fixed in a gas-tight manner by means of fixing means 1.4 to the first pane sealing surface and to the second pane sealing surface. The plurality of spacer struts 1.3 are implemented as a partially open frame and arranged such that a receiving opening 1.5 is implemented between two spacer struts 1.3, which opening is dimensioned such that a third pane element 2.1 fastened on the closure component 2 can be inserted through it into the insulating glass volume 3 of the double glazing component 1.

[0077] One of the spacer struts 1.3 is implemented as a holder strut 1.31 and has a receiving opening 1.5 that is dimensioned such that the third pane element 2.1 can be inserted through it into the insulating glass volume. The holder strut 1.31 surrounds the receiving opening 1.5 on all sides. Adjacently connecting to the holder strut 1.31, a first sealing section 1.6 on the first pane element 1.1 is exposed, and a second sealing section 1.7 on the second pane element 1.2 is exposed.

[0078] The third pane element 2.1 is part of the closure component 2 that is further provided, in addition to the third pane element 2.1 that can be inserted into the double glazing component 1, a closure sealing means (not shown) for the gas-tight closing of the insulating glass volume after arrangement of the closure component 2 on the receiving opening 1.5. The closure component 2 also has a cover element 2.2, which interacts with the closure sealing means for the gas-tight closure of the insulating glass volume 3. The cover element 2.2 is dimensioned such that it can fit sealingly between the first pane element 1.1 and the second pane element 1.2. The third pane element 2.1 is implemented as an electrically controllable pane element. The cover element 2.2 has, purely by way of example, two electrical connectors 2.7 leading from the insulating glass volume to the outside.

[0079] The spacer struts 1.3 are implemented as hollow main bodies. The hollow main body has two parallel pane contact legs (not shown), an outer leg 1.32, and two glazing interior legs 1.33, of which one is discernible. A desiccant is at least partially arranged (not shown) in the hollow main body. The hollow main body extends between the first pane element 1.1 and the second pane element 1.2. Whereas the first pane contact leg (not shown) is fixed on the first pane sealing surface of the first pane elements 1.1, the second pane contact leg (not shown) is fixed on the second pane sealing surface of the second pane element 1.2.

[0080] FIG. 2 depicts another possible embodiment of the modular system according to the invention. The modular system depicted in FIG. 2 corresponds to the modular system depicted in FIG. 1 with the differences that the spacer has no holder strut 1.31. The spacer struts 1.3 are arranged U-shaped along the pane edges of the outer pane 1.1,1.2. Upwardly, the spacer strut is completely lacking such that the receiving opening 1.5 is formed between the two vertically extending spacer struts 1.3. Also, the third pane element 2.1 of the closure component 2 is surrounded along its outer edges with a further spacer element 2.4. This additional spacer element 2.4 is implemented as a so-called double spacer. It has two parallel hollow chambers to accommodate desiccant, which are separated from one another by a groove. The additional spacer element can be positioned on the outer edges of the third pane element 2.1 with this groove. The outer edges of the third pane element 2.1 are protected thereby when the cover element 2.2 is joined with the double glazing component 1.

[0081] FIG. 3 depicts a cross-section of the second embodiment of the modular system depicted in FIG. 2 in the assembled state, i.e., the closure component 2 has been slid into the double glazing component 1 in the direction of the arro yeah w and arranged therein such that a multiple insulating glazing unit is formed. The cross-sectional plane is identified in FIG. 2 with III. Consequently, FIG. 3 depicts a triple insulating glazing unit after completion. The spacer strut 1.3 is arranged between the first pane element 1.1 and the second pane element 1.2 and is fixed by fixing means 1.4 to the first pane sealing surface and to the second pane sealing surface in a gas-tight manner. The closure component 2 is inserted into the double glazing component 1 such that an insulating glass volume 3.1 is formed between the first pane element 1.1 and the third pane element 2.1 and another insulating glass volume 3.2 is formed between the second pane element 1.2 and the third pane element 2.1, which insulating glass volumes are separated from one another by the third pane element 2.1 plus the additional spacer 2.4, which is arranged along the outer edges 2.3 of the third pane element 2.1.

[0082] The additional spacer 2.4 is implemented as a hollow and preferably polymeric main body in the form of a so-called double spacer, which can be glass fiber reinforced. The additional spacer 2.4 comprises a first pane contact leg 2.41, a second pane contact leg 2.42 running parallel thereto, a first glazing interior leg 2.43, a second glazing interior leg 2.44, and an outer leg 2.45. Situated between the outer leg 2.45 and the first glazing interior leg 2.43 is a first hollow chamber 2.46, whereas a second hollow chamber 2.47 is arranged between the outer leg 2.45 and the second glazing interior leg 2.44. Situated between the two hollow chambers 2.46, 2.47 is a groove 2.48, which runs parallel to the pane contact legs 2.41, 2.42. Two groove side legs (not shown) of the groove 2.48 are formed by the walls of the two hollow chambers 2.46, 2.47, whereas a bottom surface (not shown) of the groove 2.48 is directly adjacent the outer leg 2.45. The outer leg 2.45 runs, for the most part, perpendicular to the pane contact legs 2,41, 2.42 and parallel to the glazing interior legs 2.43, 2.44. The glazing interior legs 2.43, 2.44 have openings (not shown) at regular intervals, which, in each case, connect one of the hollow chambers 2.46, 2.47 to the respective insulating glass volume 3.1, 3.2. The first hollow space 2.46 and the second hollow space 2.47 are, at least in sections, filled with a desiccant 2.5 that can absorb humidity from the insulating glass volumes 3.1, 3.2.

[0083] The first pane contact leg 2.41 is fixed on the first pane element 1.1, and the second pane contact leg 1.2 is fixed on the second pane element 1.2. The glazing interior legs 2.43 or 2.44 are adjacent the insulating glass volumes 3.1 or 3.2, respectively. The first glazing interior leg 2.43 is positioned between the first pane element 1.1 and the third pane element 2.1, whereas the second glazing interior leg 2.44 is arranged between the third pane element 2.1 and the second pane element 1.2. The outer leg 2.45 is the side of the additional spacer 2.4 opposite the glazing interior legs 2.43, 2.44, which face away from the insulating glass volumes 3.1, 3.2. The outer leg 2.45 is arranged either adjacent the spacer struts 1.3 or the cover part 2.2. The groove 2.48 encloses the outer edges 2.3 of the third pane element 2.1.

[0084] The closure component 2 has the electrical connector 2.7, which is arranged through the cover part 2.2 in a gas-tight manner such that the electrical connector 2.7 electrically contacts the third pane element 2.1 implemented as a functional glass pane.

[0085] FIG. 4a depicts another cross-section of the modular system according to the invention depicted in FIG. 2 in the assembled state, i.e., the closure component 2 is slid into the double glazing component 1 in the direction of the arrow and arranged therein such that a multiple insulating glazing unit is formed. The cross-sectional plane is identified with IVa. Consequently, FIG. 4a depicts a triple insulating glazing unit after completion. Two spacer struts 1.3 are arranged between the first pane element 1.1 and the second pane element 1.2 and fixed by fixing means 1.4 to the first pane sealing surface and to the second pane sealing surface in a gas-tight manner. The two spacer struts 1.3 are arranged between opposing edges of the two pane elements 1.1, 1.2. The insulating glass volume 3.1 is formed between the first pane element 1.1 and the third pane element 2.1, and the other insulating glass volume 3.2 is formed between the second pane element 1.2 and the third pane element 2.1 such that the insulating glass volumes are separated from one another by the third pane element 2.1 plus the additional spacer 2.4, which is arranged along the outer edges 2.3 of the third pane element 2.1.

The embodiment depicted in FIG. 4b corresponds to the embodiment depicted in FIG. 4a with the difference that the third pane element has at least two sub-pane elements 2.11, 2.12, that are connected and fixed to one another by at least one holder 4. The holder 4 is implemented such that it encloses the first sub-pane element 2.11 on its inner edge 2.13 and the second sub-pane element 2.12 on its inner edge 2.14, whereas the outer edges 2.3 of the sub-pane elements 2.11, 2.12 are arranged in the groove 2.48 of the spacer 2.4.

[0087] FIG. 5 depicts an enlarged partial view of the modular system depicted in FIG. 3 in the region of the closure component 2. The modular system is assembled to form the multiple insulating glazing unit. The first pane contact leg 2.41 is arranged on the first pane element 1.1, and the second pane contact leg 2.42 is arranged on the second pane element 1.2.

A closure sealing means 2.6 in the form of a butyl rubber layer is arranged between the second pane element 1.2 and the second pane contact leg 2.42. Before the joining of the double glazing component 1 and the closure component 2, the closure sealing means 2.6 can be fixed either on the double glazing component 1 or on the closure component 2. It is likewise conceivable for it to be arranged in sections on the double glazing component 1 and in sections on the closure component 2, provided the required gas tightness is ensured in the assembled state.

[0089] FIG. 6b depicts an enlarged partial view of the modular system depicted in FIG. 5 in another possible embodiment. As an alternative or in addition to the embodiment depicted in FIG. 6a, the modular system can have a sealingly arranged closure sealing means 2.6, for example, in the form of a butyl rubber cord arranged in a groove, between the outer edge 1.8 of the second pane element 1.2 and the cover part 2.2.
