Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of windows, and in particular to a mounting and fixing structure for an outer frame and an inner frame of a window.

BACKGROUND

[0002] There are various types of windows and frames for motorhomes. In the prior art, a frame consists of an inner frame and an outer frame that are made separately. In addition to the installation environment and other factors, a mounting and fixing system and method of a window usually depend on the budge.

[0003] The outer frame is fixed to a wall opening of the motorhome from the exterior. The inner frame is fixed to the wall from the interior. Then, the inner frame is fixed to the outer frame through screws. For aesthetic needs, caps are usually used to cover the screws in the inner frame.

[0004] However, the caps can be easily disconnected due to vibration during traveling. In addition, the caps can be seen even though they are well mounted in the frame.

DETAILED DESCRIPTION

[0015] A clear and complete description of the technical solutions in the embodiments of the present invention will be given below, in combination with the accompanying drawings in the embodiments of the present invention. Apparently, the embodiments described below are a part, but not all, of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without inventive efforts fall within the scope of protection of the present invention.

[0016] To solve the problems in the prior art, the present invention provides a mounting and fixing structure of an outer frame and an inner frame of a window. In the present invention, parts are closely fitted to prevent from losing, and the inner frame and the outer frame of the window are firmly mounted.

[0017] To make the above objective, characteristics and advantages of the present invention more understandable, the present invention will be further described below in detail in combination with the accompanying drawings and specific embodiments.

[0018] As shown FIG. 1 to FIG. 15, the present invention provides a mounting and fixing structure of an outer frame and an inner frame of a window, which includes an outer frame part and an inner frame part. The outer frame part is mounted at a wall opening 1 while the inner frame part is fitted to the outer frame part. U-shaped angle brackets 3 are fixedly connected with an upper crossbeam 2 of the outer frame part. Recessed angle brackets 5 are fixedly connected with two side vertical beams 6 and a lower crossbeam 7 of the outer frame part. T-shaped profiles 13 are fixedly connected with an upper crossbeam of the inner frame part. O-shaped profiles are fixedly connected with two side vertical beams and a lower crossbeam of the inner frame part. The T-shaped profile 13 and the U-shaped angle bracket 3 are fitted together. The O-shaped profile and the recessed angle bracket 5 are fitted together.

[0019] The U-shaped angle bracket 3 is fitted to an outer side of the upper crossbeam of the outer frame part through a screw 4. The U-shaped angle bracket 3 includes a slot 8 located in one side of a main body of the U-shaped angle bracket. One side of the slot 8 is a tilted side plate 9. The T-shaped profile 13 is inserted into the slot 8. One side of a main body of the T-shaped profile 13 is integrally connected with a hanging plate 11. The hanging plate 11 is inserted into the slot 8 of the U-shaped angle bracket 3.

[0020] The recessed angle brackets 5 are fitted to outer sides of the two side vertical beams and an outer side of the lower crossbeam of the outer frame part through screws 4. A snapslot 10 is integrally arranged on one side of the recessed angle bracket 5. The O-shaped profile is inserted into the snapslot 10. An O-shaped bulge 12 is integrally connected with one side of a main body of the O-shaped profile. The O-shaped bulge 12 is fitted to the snapslot 10.

[0021] The slot 8 and the snapslot 10 are female connectors while the hanging plate 11 and the O-shaped bulge 12 are male connectors. When the female connectors of the outer frame part are right connected with the male connectors of the inner frame part, all connectors are hidden in the inner frame and are invisible, thereby avoiding a problem that a cap is lost due to the fact that the cap is exposed in the exterior in the background.

[0022] To meet mounting requirements of the window, multiple U-shaped angle brackets 3 or recessed angle brackets 5 can be respectively and uniformly distributed on the upper crossbeam, the two side vertical beams and the lower crossbeam of the outer frame part according to different specifications of the wall opening. The T-shaped profile 13 and the O-shaped profiles of the upper crossbeam, the two side vertical beams and the lower crossbeam of the inner frame part are arranged respectively corresponding to the U-shaped angle brackets 3 and the recessed angle brackets 5. When the windows need to be mounted in the same specification of the wall openings but on different thicknesses of walls of a motorhome, only different U-shaped angle brackets 3 and the recessed angle brackets 5 need to be changed.

[0023] The mounting and fixing structure of an outer frame and an inner frame of a window in the present invention has the following mounting steps:
a required specification of the outer frame of the window is mounted in the wall opening of the motorhome from the exterior of the wall; the U-shaped angle brackets 3 and the recessed angle brackets 5 are respectively fixed to the outer frame through the screws 4 from the interior of the motorhome; the T-shaped profile 13 on the upper portion of the inner frame is hung in the slots 8 of the U-shaped angle brackets 3 fixed to the upper portion of the outer frame; the O-shaped profiles of the inner frame are snapped into the recessed angle brackets 5 fixed to the outer frame by properly pressing the two sides and the lower portion of the inner frame, respectively (as shown in FIG. 13/14). Therefore, the inner frame and the outer frame of the window are mounted.

[0024] Several examples are used for illustration of the principles and implementation methods of the present invention. The description of the embodiments is used to help illustrate the method and its core principles of the present invention. In addition, a person of ordinary skill in the art can make various modifications in terms of specific embodiments and scope of application in accordance with the teachings of the present invention. In conclusion, the content of this specification shall not be construed as a limitation to the present invention.
