Description

Technical Field

[0001] The present invention relates to the technical field of sliding windows, and more specifically, to a lift sliding window. Background Art

[0002] In the closed state of the lift sliding window, the window sash is in a lowered state. The rubber strip on the window sash and the track on the window frame generate pressure due to the self-weight of the window sash, achieving a sealing effect and reaching high water tightness and air tightness. When the window is opened, through the elevation of the pulley, the window sash rises to completely separate the rubber strip from the track, thereby reducing the opening and closing force of the window sash and ensuring flexible opening.

[0003] The handle of a conventional lift sliding window is installed on the longitudinal member of the window sash. By rotating the handle, the transmission connecting rod and the steering device at the corner of the sash are driven, and then the lifting pulley is connected through the connecting rod to realize the lifting and lowering of the sliding sash. The lifting pulley is a pulley that can convert the horizontal displacement into the lifting displacement. For example, in the patent: A safety pulley for a lift sliding window, patent number: 2016208664202, generally an arc-shaped track is provided on the horizontal rod of the pulley. When the horizontal rod moves horizontally, the pulley moves in the arc-shaped track, and the pulley will move horizontally and vertically at the same time.

[0004] However, there are several deficiencies in the conventional lift sliding window. 1. Since the handle needs to be installed on the longitudinal member of the window sash, a part of the longitudinal member of the window sash must be reserved for installing the handle, resulting in a relatively large longitudinal member of the window sash, insufficient overall permeability, and poor heat insulation effect because the longitudinal member of the window sash must be large enough to install the handle. 2. Since the handle is installed on the longitudinal member of the window sash, the conventional installation position is generally in the middle of the longitudinal member of the window sash. At this time, the handle is at a certain height from the ground, making it difficult for the elderly, children, and disabled people to open the window. 3. Since the handle is installed on the surface of the longitudinal member of the window sash, the non-overlapping surface between the longitudinal members of the window sash and the window frame will be very large. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies of the prior art and provide a lift sliding window with the handle installed in the lower profile, which can not only retain the high waterproofness, wind resistance, and heat insulation of the conventional sliding window, but also make the window sash have higher permeability and convenience.

[0006] To achieve the above purpose, a lift sliding window is designed, which is characterized by including: a handle, the handle is arranged on the lower horizontal member of the window sash; a set of lifting pulley plus connecting rod, the lifting pulley and the connecting rod are arranged inside the lower horizontal member of the window sash, the lifting pulley is connected to the handle through the connecting rod, and the rotation of the handle drives the connecting rod to make the lifting pulley move up and down, thereby lifting or lowering the window sash; the handle, the connecting rod, and the lifting pulley are all installed in the same direction.

[0007] It also includes a locking hook installed at the joint of the longitudinal and transverse members of the window sash, a locking seat installed at the corner of the window outer frame, and the window sash descending pulley drives the locking hook into the locking seat for locking.

[0008] Preferably, the handle has a concealed structure.

[0009] Preferably, a lifting handle is provided in the middle of the handle. One end of the lifting handle is connected by a rotating shaft, and the other end can rotate around the rotating shaft after being pulled open.

[0010] Preferably, a lifting handle is provided in the middle of the handle, and the lifting handle can be flipped by 180°.

[0011] Preferably, the handle is an electric structure.

[0012] Preferably, the handle is connected to the connecting rod through a gear transmission device.

[0013] Preferably, the handle is directly connected to the connecting rod.

[0014] Compared with the prior art, the advantages of the present invention are as follows:

[0015] 1. The transmission handle, the transmission mechanism and the pulley are all in one direction, and the transmission efficiency is higher;

[0016] 2. The opening and closing force of the handle is smaller, the assembly relationship is less, the cumulative assembly tolerance is less, and the accuracy is more accurate;

[0017] 3. The handle can adopt a concealed structure, which can make the two sliding sashes completely coincide, maximize the ventilation area of the window, and at the same time facilitate the selection of different types of window screens;

[0018] 4. Since the longitudinal member of the window sash does not need to be equipped with transmission hardware, the area of the longitudinal member of the window sash can be reduced, which not only saves materials but also increases the lighting area of the window, and at the same time improves the heat preservation and sound insulation performance of the doors and windows;

[0019] 5. The hardware is simple and effective, reducing the manufacturing difficulty, improving the manufacturing efficiency, and effectively ensuring the stability of the door and window quality;

[0020] 6. The handle is installed on the lowest horizontal member of the sliding window, and the height is much lower than that of the traditional handle, which is suitable for various people to open and improves the comfort of use;

[0021] 7. Since the area of the longitudinal member is reduced, the economy is greatly improved and the cost performance is improved. Description of the Drawings

[0034] The present invention will be further described below with reference to the accompanying drawings. The structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] See Figure 3 and Figure 11 : The lifting pulley and the connecting rod are arranged inside the horizontal rod. There is a groove at the lower part of the window sash, and a handle is arranged in the groove. Under normal circumstances, the handle is completely arranged inside the groove, which is a hidden structure. A handle grip is arranged on the handle. When in use, pull out the handle grip. Since one end of the handle grip is connected to a rotating shaft, hold the handle grip and rotate it around the rotating shaft. The handle is connected to the connecting rod through a gear structure. Through the rotation of the handle grip and then through the transmission of the gear structure, the connecting rod is driven to move horizontally. The horizontal movement of the connecting rod causes the pulley to lift, and the lifting of the pulley drives the window sash to lift, thus facilitating window opening.

[0036] See Figure 4:The lifting pulley and the connecting rod are arranged inside the horizontal rod. There is a groove at the lower part of the window sash, and a handle is arranged in the groove. In normal times, the handle is completely set inside the groove, which is a hidden structure. There is a lifting handle on the handle. When in use, pull out the lifting handle. Since one end of the lifting handle is connected to a rotating shaft, hold the lifting handle and make it rotate around the rotating shaft. The handle is directly connected to the connecting rod. The rotation of the lifting handle makes the connecting rod move horizontally. The horizontal displacement of the connecting rod makes the pulley lift, and the lifting of the pulley drives the window sash to lift, thus facilitating the opening of the window.

[0037] See Figure 5 :The handle can be replaced with a folding type. In the normal state, the handle is still arranged in the groove, which is a hidden structure. There is a rotating shaft in the middle of the handle. One end of the lifting handle is connected to the rotating shaft, and the other end is for holding by hand. When in use, hold the lifting handle and make it flip left and right around the rotating shaft. The flipping of the lifting handle drives the connecting rod through a gear structure. The connecting rod makes the pulley rise, and then the window sash rises, facilitating the opening of the window.

[0038] See Figure 6 :The folding handle can also be directly connected to the connecting rod. Through the flipping of the lifting handle, it drives the connecting rod to move horizontally, and at the same time drives the pulley to rise, and then the window sash rises, facilitating the opening of the window.

[0039] See Figure 7 :The handle can be electric. Control the rotation of the motor through a remote switch, make the pulley rise, and then the window sash rises, facilitating the opening of the window.

[0040] See Figures 1 - 2 , Figures 8 - 10 :The locking hook is installed at the joint of the longitudinal rod and the horizontal rod of the window sash; the locking seat is installed at the corner of the window frame; when the window sash is opened, that is, when the handle makes a rotating or flipping movement, the handle will make the horizontal rod of the lifting pulley move horizontally through a gear structure or directly through the connecting rod. At this time, the pulley will move along an arc track in an arc motion. The vertical movement of the pulley will drive the window sash to lift, facilitating the opening of the window sash. The horizontal movement of the pulley will make the locking hook disengage from the locking seat. When the window sash is closed, the locking hook locks the locking seat to prevent the window sash from being pried out of the track when it is closed, playing an anti-theft role.

[0041] The locking hook installed on the window sash and the locking seat installed on the window frame effectively perform the function of locking the window through the lifting and lowering of the pulley. As the pulley descends, the locking hook on the window sash locks the locking seat. As the pulley rises, the locking hook disengages from the locking seat.
