Description

Technical Field

[0001] This utility model relates to the field of casement window structure technology, specifically to a frame and sash system for an extremely narrow casement window. Background Technology

[0002] Casement windows are commonly used in buildings, and they have the advantages of large opening area and good ventilation. However, most casement windows currently on the market are made of wide structure, which greatly affects the aesthetics and increases the consumption of aluminum materials. In addition, casement windows made of wide structure are complicated to install.

[0003] To achieve an extremely narrow frame, existing casement windows make the entire frame profile narrower. However, traditional casement windows have a lock box inside the sash, and a handle is set on the decorative surface of the sash to connect to the lock box and control the opening and closing of the casement window. Due to the structural limitations of the lock box and handle, the width of the traditional casement window sash cannot be narrowed to an extremely narrow level. Therefore, in order to pursue a larger opening area and better lighting effect, improvements are needed. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes a frame and sash system for an extremely narrow casement window, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A frame and sash system for an ultra-narrow casement window includes a frame body, a glass sash frame, a guardrail body, and a screen sash frame. The guardrail body and the screen sash frame are installed on the interior side of the frame body. The glass sash frame is formed by a first ultra-narrow thermally broken profile.

[0006] The first ultra-narrow thermal break profile includes a first profile disposed on the side near the outside, a second profile disposed on the side near the inside, and a first thermal insulation strip sandwiched between the first profile and the second profile. The second profile is bent away from the frame body and its inner side is fitted with the guardrail body to form a lock box installation chamber.

[0007] A rotating handle with its output end horizontally inserted along the thickness direction of the second profile is provided between the screen frame and the guardrail body.

[0008] As an improvement to the above solution, the frame body is formed by a second ultra-narrow thermal break profile, the second ultra-narrow thermal break profile including a third profile disposed near the outside, a fourth profile near the inside, and a second thermal insulation strip sandwiched between the third profile and the fourth profile.

[0009] As an improvement to the above solution, the first profile and the third profile are positioned correspondingly, the first heat insulation strip and the second heat insulation strip are positioned correspondingly, and a first sealing strip is provided on the end face of the first heat insulation strip facing the second heat insulation strip, and the first sealing strip and the first heat insulation strip are snapped together and fixed.

[0010] As an improvement to the above solution, a glass fan buckle plate is snapped onto the side of the first profile away from the frame body, and the glass fan buckle plate and the second profile are combined to form a clamp-shaped mounting opening for installing the glass fan.

[0011] As an improvement to the above solution, the main body of the guardrail includes a guardrail frame and guardrail bars. The guardrail frame is formed by four guardrail profiles arranged in a rectangle, and the guardrail bars are fixed to the inside of the guardrail profiles.

[0012] As an improvement to the above solution, the protective frame profile includes an installation part that fits with the second profile and a connecting part that fits with the frame body. The installation part and the connecting part are integrally extruded and formed, and the protective railing strip is screwed to the installation part for fixation.

[0013] As an improvement to the above solution, the frame body is provided with a T-shaped positioning clip extending toward the connecting part, the connecting part is provided with a snap-fit ​​protrusion that cooperates with the T-shaped positioning clip, and a second sealing strip is provided adjacent to the snap-fit ​​protrusion.

[0014] As an improvement to the above solution, the connecting part has a groove on the side face away from the frame body. The connecting part and the frame body are fixed by screwing screws along the bottom of the groove. A decorative buckle is provided at the groove opening.

[0015] The beneficial effects of this utility model are as follows: In this technical solution, the glass fan frame is formed by the first ultra-narrow thermally broken profile. The first and second profiles with ultra-narrow decorative surfaces are used, and the lock box and handle structure that are traditionally set in the glass fan frame are transferred to the space between the main screen frame and the glass fan frame of the guardrail. This reduces the width of the glass fan, making it extremely narrow and having a larger opening area and lighting effect. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0025] like Figure 1 As shown, a frame and sash system for an ultra-narrow casement window includes a frame body 1, a glass sash frame 2, a guardrail body 3, and a screen sash frame 4. The guardrail body 3 and the screen sash frame 4 are installed on the frame body 1 near the indoor side. The glass sash frame 2 is formed by a first ultra-narrow thermally broken profile 21.

[0026] In the technical solution of the frame-sash system of this utility model, the glass sash frame 2, the guardrail body 3, and the screen sash frame 4 are all arranged inside the frame body 1. The glass sash frame 2 is arranged on the side closer to the outside, the screen sash frame 4 is arranged on the side closer to the inside, and the guardrail body 3 is arranged between the screen sash frame 4 and the glass sash frame 2. The gap between the glass sash frame 2 and the guardrail body 3 is provided with a lock box mounting chamber 5 for accommodating the lock box assembly, thereby reducing the light-blocking area of ​​the glass sash frame 2 and the frame body 1, so that the window sash has a larger opening area and better lighting effect.

[0027] In the technical solution of the glass fan frame 2 of this utility model, the glass fan frame 2 is formed by four first ultra-narrow thermal break profiles 21. The first ultra-narrow thermal break profile 21 includes a first profile 22 disposed on the side near the outside, a second profile 23 disposed on the side near the inside, and a first heat insulation strip 24 sandwiched between the first profile 22 and the second profile 23. The second profile 23 is bent away from the frame body 1, and its inner side is fitted with the guardrail body 3 to form a lock box installation chamber 5.

[0028] It should be noted that the first profile 22 has an extremely narrow decorative surface facing the outside. Traditional glass sash profiles have both a clamp-shaped mounting opening 7 for installing glass and a lock box mounting chamber 5 for installing lock boxes, resulting in a wider decorative surface for traditional glass sash profiles. In the first extremely narrow thermally broken profile 21, after the first profile 22 and the second profile 23 are combined to form the clamp-shaped mounting opening 7 for installing glass, the lock box mounting chamber 5 is formed in the interlayer between the guardrail body 3 and the glass sash body by utilizing the gap between the second profile 23 and the guardrail frame. Compared with traditional glass sash profiles, the first extremely narrow thermally broken profile 21 reduces the width of one lock box mounting chamber 5, resulting in a larger opening area and lighting effect.

[0029] Furthermore, in the above scheme, a rotating handle 6 with its output end horizontally inserted along the thickness direction of the second profile 23 is provided between the screen frame 4 and the guardrail body 3. The rotating handle 6 is connected to the lock box installation chamber 5 in a side-mounted manner, and the glass screen is opened by rotating the rotating handle 6.

[0030] In the technical solution of the frame body 1 of this utility model, the frame body 1 is formed by a second ultra-narrow thermal break profile 11. The second ultra-narrow thermal break profile 11 includes a third profile 12 disposed on the side near the outside, a fourth profile 13 disposed on the side near the inside, and a second heat insulation strip 14 sandwiched between the third profile 12 and the fourth profile 13.

[0031] Furthermore, in the above scheme, the positions of the first profile 22 and the third profile 12 correspond, and the positions of the first thermal insulation strip 24 and the second thermal insulation strip 14 correspond. It should be noted that the first thermal insulation strip 24 and the second thermal insulation strip 14 are used to block the heat conduction between the indoor and outdoor areas. The first profile 22 and the third profile 12 are close to the outdoor area. After sunlight, heat is conducted towards the indoor area through the first profile 22 and the third profile 12. The positions of the first thermal insulation strip 24 and the second thermal insulation strip 14 are aligned so that the frame and sash system blocks the outdoor heat at the positions of the first thermal insulation strip 24 and the second thermal insulation strip 14, avoiding the alternating transfer of heat between the first ultra-narrow thermally broken profile 21 and the second ultra-narrow thermally broken profile 11.

[0032] The end face of the first heat insulation strip 24 facing the second heat insulation strip 14 is provided with a first sealing strip 25. The first sealing strip 25 is snapped and fixed to the first heat insulation strip 24. The first sealing strip 25 is used to seal the glass fan frame 2 and the frame body 1.

[0033] Furthermore, in the above scheme, the first profile 22 is fitted with a glass fan buckle plate 26 on the side away from the frame body 1, and the glass fan buckle plate 26 and the second profile 23 are combined to form a clamp-shaped mounting port 7 for installing the glass fan.

[0034] In the technical solution of the guardrail body 3 of this utility model, the guardrail body 3 includes a guardrail frame and guardrail grid strips 31. The guardrail frame is formed by four guardrail profiles 32 arranged in a rectangle, and the guardrail grid strips 31 are fixed to the inner side of the guardrail profiles 32.

[0035] Furthermore, in the above scheme, the protective frame profile 32 includes an installation part 321 that fits with the second profile 23 and a connecting part 322 that fits with the frame body 1. The installation part 321 and the connecting part 322 are integrally extruded and formed. The protective railing strip 31 is screwed and fixed to the installation part 321 by screws. Specifically, the connecting part 322 fits with the inner surface of the fourth profile 13. The second profile 23, the connecting part 322, and the installation part 321 are combined to form a lock box mounting chamber 5 for mounting the lock box.

[0036] Furthermore, in the above solution, the frame body 1 is provided with a T-shaped positioning clip 15 extending toward the connecting part 322, and the connecting part 322 is provided with a snap-fit ​​protrusion 323 that cooperates with the T-shaped positioning clip 15. The connecting part 322 and the fourth profile 13 are positioned and installed by the T-shaped positioning clip 15 and the snap-fit ​​protrusion 323. The connecting part 322 is provided with a second sealing strip 33 adjacent to the snap-fit ​​protrusion 323. The second sealing strip 33 is sandwiched between the fourth profile 13 and the protective frame profile 32 to achieve a sealing and waterproofing effect.

[0037] Furthermore, in the above solution, the connecting part 322 has a groove 324 on the side face away from the frame body 1. The connecting part 322 and the frame body 1 are fixed by screwing screws along the bottom of the groove 324. A decorative buckle plate 34 is provided at the groove opening of the groove 324. The decorative buckle plate 34 covers the screws. After the screws are screwed into the groove 324 to fix the connecting part 322 and the frame body 1, the groove 324 is covered by the decorative buckle plate 34 so that the screws are not exposed.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
