Description

A variable mullion Technical Field

[0001] This utility model relates to the field of window frame profile technology, specifically a variable mullion. Background Technology

[0002] Currently, in the field of building doors and windows, insulated casement windows are widely used due to their excellent thermal insulation performance, which effectively reduces building energy consumption and improves indoor comfort. Insulated casement windows are mainly divided into two types: inward-opening windows and outward-opening windows, which differ in function, appearance, and usage scenarios.

[0003] Currently, when the industry needs to convert inward-opening windows into outward-opening windows, as shown in Figure 3, the usual practice is to add an additional steering member 2 on the side of the mullion 3 facing the outward-opening sash 1.

[0004] This practice has significant drawbacks: on the one hand, the additional profile material increases the variety and quantity of materials customers need to prepare, occupies more storage space, and significantly increases inventory management costs; on the other hand, profile material often requires specific molds for production, which undoubtedly increases mold-making costs, is not only time-consuming but also places a significant financial burden on customers. This problem not only limits the development of design flexibility and customization for insulated casement windows but also hinders companies from reducing costs and improving market competitiveness. Therefore, there is an urgent need for a new profile to replace the profile material in order to solve the problem of increased inventory and mold-making costs caused by profile material when converting inward-opening casement windows to outward-opening sashes. Summary of the Invention

[0005] To address the issue that current insulated casement window series require the addition of a turning material when converting an inward-opening window to an outward-opening sash, thus increasing customer material inventory and mold-making costs, this utility model provides a variable mullion.

[0006] This utility model is achieved using the following technical solution:

[0007] A variable mullion includes a mullion frame, the mullion frame includes a heat insulation mounting plate, the outer surface of the heat insulation mounting plate is provided with heat insulation clips, connecting plates are fixedly distributed at both ends of the heat insulation mounting plate, a mullion panel is fixedly fixed at the end of the connecting plate, a rubber strip groove is provided at one end of the mullion panel, and a first groove is provided on the outer surface of the connecting plate away from the rubber strip groove.

[0008] In implementation, the mullion frame is used. Two identical mullion frames are inserted together via thermal insulation. The first slots on the two mullion frames face opposite directions, meaning that mullion installation can be achieved using only two identical mullion frames. This eliminates the need for assembling and processing multiple profiles, maximizing material savings and avoiding waste. Specifically, for differentiation based on installation location, the mullion frame includes an inner mullion frame and an outer mullion frame. The inner and outer mullion frames have identical structures. The inner mullion frame is connected to the outer mullion frame via thermal insulation. The outer mullion frame mates with the outward-opening sash. The outward-opening sash includes both the inner and outer frames of the inner mullion frame.

[0009] The mullion frame includes a heat insulation mounting plate, the outer surface of which is provided with heat insulation clips, and connecting plates are fixed at both ends of the heat insulation mounting plate. A mullion panel is fixed at the end of the connecting plate, and a rubber strip groove is provided at one end of the mullion panel. A first groove is provided on the outer surface of the connecting plate away from the rubber strip groove.

[0010] Specifically, the inner mullion frame includes an inner insulation mounting plate, an inner insulation clip on the outer surface of the inner insulation mounting plate, connecting plates fixed at both ends of the inner insulation mounting plate, a pressure strip groove on the outer surface of the connecting plate away from the outward opening fan, an inner mullion panel installed at the end of the connecting plate, the inner mullion panel being flush with the inner surface of the outward opening fan, and a rubber strip groove at the end of the inner mullion panel facing the outward opening fan; the inner frame of the outward opening fan has a bent portion recessed into the profile, the bent portion engaging with the rubber strip groove at the end of the inner mullion panel.

[0011] The outer mullion frame includes an outer insulation mounting plate. The outer surface of the outer insulation mounting plate is provided with an outer insulation clip. The outer insulation clip and the inner insulation clip are connected by an insulation insert. Connecting plates are fixed at both ends of the outer insulation mounting plate. The outer surface of the connecting plate facing the outward opening fan is provided with a hinge slot. The end of the connecting plate is equipped with an outer mullion panel. The outer mullion panel is located inside the outer panel of the outward opening fan.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The variable mullion provided by the present invention solves the problem that when insulated casement windows are made into outward-opening windows, it is necessary to add a steering material. By changing the mullion type, the flexibility of the mullion is improved, the use of steering material is reduced, the customer's needs for making outward-opening windows are met, and inventory and mold opening costs are reduced. At the same time, inventory can be reduced and enterprise costs are lowered. Attached Figure Description
