Integral insertion and connection profile fittings special for casement window and vertical hinged door

Abstract

The invention provides integral insertion and connection profile fittings special for a casement window and a vertical hinged door. The profile fittings include a cash profile, a rotating shaft and two shaft caps. Rotating shaft grooves runs through the longitudinal two ends of the cash profile, rotating shafts are inserted into the rotating shaft grooves, the two ends of each rotating shaft stretches out from the two ends of the cash profile respectively, the two ends of each rotating shaft are sleeved with the two shaft caps, and the rotating shafts can rotate in the two shaft caps. The profile fittings can effectively overcomes shortcomings existing in the prior art, casements and glass do not need bolts for fixation, the profile fittings are stable and firm and does not fall off, the safety performance of the casement window and a door is effectively improved, and the potential danger of falling, breaking, aging and loosening of parts of casements is completely eliminated.

Description

technical field [0001] The invention relates to the technical field of a casement window structure, belongs to the field of safety structures of a window sash structure, and specifically relates to a casement window structure in which a window frame and a window sash are integrally interspersed and connected. Background technique [0002] Casement windows or casement doors are divided into push-pull and top-hung. Its advantages are large opening area, good ventilation, good sealing performance, excellent sound insulation, heat preservation, and impermeability, and the inward opening type is convenient for window cleaning; the outward opening type does not occupy space when opening. [0003] In the current field of casement window or casement door technology, when the outward-opening window is opened, the sash part protrudes to an outdoor space, and it is easy to be damaged when the wind blows; Part and connection with the window frame, its role and function are very importa...

Problems solved by technology

In the same way figure 2 As shown, the hinge connection method is also fixed and installed by screws, and the characteristics of casement windows or casement doors, in daily use, especially now that more and more high-rise buildings are constantly being built, most of them use outward opening. The casement window or casement door design, therefore, the applicant considers that such a situation will cause the bolt part to be in direct contact with a large amount of rainwater and sunlight exposure, which is very easy to rust and oxidize, especially in humid areas or coastal cities , is severely corroded by the sea breeze, and its aging degree will inevitably be accelerated, and the aging bolt structure will inevitably lead to weakening of the connection and fixing strength, thereby increasing the risk and probability of the window falling

It can be seen that there are great potential risks and safety hazards in the casement window or casement door and window sash structure of the traditional structure.

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 chute will also age and rust due to the corrosion of external dust and air and rain, which makes the window sash difficult to open. The situation of smooth opening and closing makes the operation difficult. Due to the difficulty of operation, the user will often exert more force to move the window sash at this time. Such forceful operation will aggravate the loosening and aging speed of the fixing screws, which will inevitably cause cause safety hazard

[0004] In the same way, the market lacks corresponding stable and safe casement windows or doors, special rotating accessories or profiles on the casement doors, and the profile and accessories industry lacks absolutely safe window and door profiles.
