Description

Technical Field

[0001] The invention relates to the technical field of a casement window structure, belonging to the field of safety structures of window sash structures, and specifically to a casement window structure in which a window frame and a window sash are integrally interlaced and connected. Background Art

[0002] Casement windows or doors are divided into push-pull type and top-hung type. Their advantages are large opening area, good ventilation, good sealing, excellent sound insulation, heat preservation and anti-seepage performance, the inner opening type is convenient for window cleaning, and the outer opening type does not take up space when opened.

[0003] In the current casement window or casement door technology, when the outward-opening window is opened, the window sash part extends to a space outside and is easily damaged when there is a strong wind. The key connection between the window sash and the window frame is used to carry the window part and connect with the window frame. Its role and function are very important. The current connection parts are divided into two types: hinge connection and hinge connection. Figure 1 The structure diagram of the hinged connection method of the conventional casement window or casement door is as follows: Figure 1 As shown, the weight of the window part of the window sash, including the window frame and the glass, is borne by the hinged connection structure, and the hinged connection structure is only fixed to the window frame by a few screws. The upper and lower hinged connection structures only have 4 to 6 screws in total, which are used to bear the 10 to 30 kg window part. Figure 2 As shown, the hinge connection method is also fixed and installed by screws, and the characteristics of casement windows or casement doors are that in daily use, especially with the continuous construction of more and higher high-rise buildings, most of them adopt outward-opening casement windows or casement doors. Therefore, the applicant considers that such a situation will cause the bolt part to be in direct contact with a large amount of rain and sunlight, and it is very easy to rust and oxidize. Especially in areas with humid climates or coastal cities, they are severely corroded by sea breezes, and their aging degree will inevitably accelerate. The aging bolt structure will inevitably lead to the weakening of the connection and fixing strength, thereby increasing the risk and probability of the window falling. It can be seen that the traditional structure of the casement window or casement door window sash structure has great potential risks and safety hazards. In addition to the hidden dangers of safety issues, in the traditional casement window or casement door structure, the exposed connecting parts such as slide rails and slide grooves will also age and rust due to corrosion from external dust and sand and air and rain, making it difficult to open and close the window sash smoothly, making it difficult to use and operate. Due to the difficulty in operation, users often use greater force to move the window sash. Such forceful operation will aggravate the loosening and aging of the fixing screws, which will inevitably cause safety hazards.

[0004] Similarly, the market lacks corresponding stable and safe casement windows or casement doors, and special rotating accessories or profiles for casement doors. The profile and accessories industry lacks absolutely safe window and door profiles. Summary of the invention

[0005] The purpose of the present invention is to effectively overcome the deficiencies in the above-mentioned prior art through design and research and development by the applicant, and to provide a profile accessory dedicated to casement windows or casement doors that is stable, secure, and will not fall off the window sash and window frame without the need for screws to fix the window sash and glass, thereby effectively improving the safety performance of the casement windows and doors themselves, and completely eliminating the potential hazards of partial falling, breaking, aging and loosening of the window sash.

[0006] Specifically, the present invention is implemented as follows: a profile accessory for integral interlaced connection specially used for casement windows and casement doors, including a window sash profile, a rotating shaft, and two shaft caps. The window sash profile is provided with rotating shaft grooves at both longitudinal ends, the rotating shaft is inserted into the rotating shaft grooves, and both ends of the rotating shaft extend out of the two ends of the window sash profile respectively. The two shaft caps are respectively mounted on the two ends of the rotating shaft, and the rotating shaft can rotate within the two shaft caps.

[0007] Furthermore, a bolt hole is provided on the middle section of the rotating shaft, and an assembly slot is provided on the side surface of the window sash profile above the bolt hole, and the control bolt is installed in the bolt hole in the assembly slot and can move in the assembly slot.

[0008] Furthermore, the length of the rotating shaft exceeds the longitudinal length of the window sash profile by at least 3 cm, and the length of the assembly slot does not exceed 3 cm.

[0009] Furthermore, the shaft cap includes a cap body and fixing ears, and the fixing ears are two pieces, which are symmetrically distributed on both sides of the opening edge of the shaft cap.

[0010] Furthermore, the shaft cap and the rotating shaft are both made of metal materials.

[0011] Furthermore, the shaft cap and the rotating shaft are both made of stainless steel.

[0012] Furthermore, the cross-sectional shape of the rotating shaft is circular, square, triangular or polygonal.

[0013] Furthermore, a rotating bearing is installed in the shaft cap, and both ends of the rotating shaft are installed in the rotating bearings.

[0014] Furthermore, the inner wall of the shaft cap is coated with lubricating oil.

[0015] Furthermore, one of the two longitudinal edges of the window sash profile has an inwardly concave installation groove, and the other side has a rotating shaft groove inside. The rotating shaft groove is composed of an inner wall of the longitudinal side wall of the window sash profile and an arc wall extending along the longitudinal side wall of the window sash profile and opened inside the window sash profile. A fixed cross arm connecting the two side walls of the window sash profile is provided below the installation groove.

[0016] The working principle of the present invention is introduced as follows: the present invention adopts a profile structure design of a specific sash edge or door edge to open a circular shaft groove with a shaft groove, and utilizes the shaft to pass through the shaft groove and then be fixed to the frame edge between the top frame and the bottom frame of the window frame near one side through a shaft cap, thereby realizing the dual effects of force and steering by relying on the shaft, overcoming the need to use screws to achieve installation and fixation, realizing a screw-free structure, and borne the weight of the window sash and glass by a longer and thicker shaft, and the shaft is fixed on the window frame, thereby stably and firmly transmitting most of the force to the window frame, and the shaft is hidden inside the profile of the window sash and window frame, and will not be affected by external wind and rain and sunlight exposure, greatly reducing the process of corrosion and aging, realizing an integrated and firm connection between the window sash and the window frame, and completely eliminating the risk of falling and the possibility of hidden dangers of the window sash without affecting the function and operating experience of the window opening and closing, and having complete safety performance. Therefore, the seemingly simple structural design of the present invention uses a simple method that has never been seen in the industry to solve the hidden dangers that have always existed in the industry, so that the outward-opening or inward-opening casement doors and windows can be completely connected safely, and the hidden danger of window sashes falling off is completely eliminated. It has a very high safety and practical value, and has far-reaching industry safety demonstration significance and market safety promotion needs. BRIEF DESCRIPTION OF THE DRAWINGS
