[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] See attached document Figures 1 to 11 A side-pressure door and window positioning wheel device and door and window system according to an embodiment of the present invention includes a fixed base 10, a drive slide plate 20, a first positioning wheel 30, a second positioning wheel 40, and a side-moving slide plate 50. The drive slide plate 20 is located on the lower side of the fixed base 10, and the first positioning wheel 30, the second positioning wheel 40, and the side-moving slide plate 50 are all located on the upper side of the fixed base 10. The first positioning wheel 30 is mounted on the side-moving slide plate 50, and the second positioning wheel 40 is mounted on the fixed base 10. The drive slide plate 20 is used to drive the side-moving slide plate 50 to move laterally in the front-back direction, wherein:

[0037] The drive slide plate 20 has a first drive unit, and the lateral slide plate 50 has a second drive unit adapted to the first drive unit. The fixed base 10 is provided with a limiting mechanism for restricting the lateral slide plate 50 from moving in the left and right directions. The drive slide plate 20 is used to connect the transmission rod 62 of the window sash system or door sash system. The first positioning wheel 30 is used to push the window sash or door sash to move laterally, thereby achieving locking and pressing or unlocking and pushing. The extension direction of the drive groove 21 is not completely parallel to the length direction of the drive slide plate 20. For example, in this embodiment, the drive groove 21 is a curve. In other embodiments, the drive groove 21 can also be a diagonal line. It is not specifically limited here, as long as it satisfies the lateral movement of the lateral slide plate 50.

[0038] Specifically: the limiting mechanism includes a lateral displacement groove 11 disposed on the upper side of the fixed base 10, the lateral displacement groove 11 extending in the front-rear direction; the first driving part is a driving groove 21 disposed on the driving slide plate 20, and the second driving part is a first positioning wheel axle 31 mounted on the lateral displacement slide plate 50, the first positioning wheel axle 31 passing through the lateral displacement slide plate 50 in the vertical direction, the upper end of the first positioning wheel axle 31 is equipped with the first positioning wheel 30, and the lower end of the first positioning wheel axle 31 is located in the driving groove 21. It can be added that the lateral movement described in this specification refers to the movement in the front-rear direction shown in the accompanying drawings. The limiting mechanism can also be limiting blocks located on the left and right sides of the side-shifting slide plate 50, thereby restricting the left and right movement of the side-shifting slide plate 50; or, the fixed base 10 can be integrally formed with limiting protrusions that restrict the left and right movement of the side-shifting slide plate 50; of course, the limiting mechanism can also be a limiting cover plate covering the upper side of the side-shifting slide plate 50, the limiting cover plate being approximately "U" shaped; the lower side of the limiting cover plate and the upper side of the side-shifting slide plate 50 maintain an movable gap, and the left and right sides of the limiting cover plate have limiting ribs extending downward for limiting the left and right movement of the side-shifting slide plate 50; the limiting mechanism can also be other structures or forms, which are not specifically limited here. In this embodiment, it also includes two pressure plates 12 for preventing the side-shifting slide plate 50 from coming off upward, the two pressure plates 12 being arranged facing each other above the groove 13 of the fixed base 10, thereby forming the aforementioned side-shifting groove 11; thus, it is not only very convenient during installation, but also not complicated to disassemble and assemble during subsequent maintenance and replacement. One side of the side-shifting groove 11 is also provided with a limiting protrusion 111 to prevent the side-shifting slide plate 50 from sliding out. Of course, the side-shifting groove 11 can also be an integrally formed T-shaped groove or dovetail groove, thus eliminating the need for the pressure plate 12. Of course, other shapes are also possible.

[0039] The first positioning wheel 30 is installed on the upper end of the first positioning wheel shaft 31, and a side shift locking point 32 is installed on the lower end of the first positioning wheel shaft 31. The side shift locking point 32 is located in the drive groove 21. The side shift locking point 32 can be a guide wheel. By setting the guide wheel, the process of the drive slide plate 20 pushing the first positioning wheel 30 is smoother.

[0040] It can be added here that: in other embodiments, the drive groove 21 can also be provided on the lateral sliding plate 50, and a push post adapted to the drive groove 21 is provided on the drive sliding plate 20. The push post is at least partially located in the drive groove 21. The specific shape of the drive groove 21 can be the same as the aforementioned drive groove 21. The lateral movement of the lateral sliding plate 50 is realized by the movement of the push post on the drive sliding plate 20 in the drive groove 21. This is a modification of the conventional drive structure for those skilled in the art, and will not be described in detail here.

[0041] Preferably, the fixed base 10 has an integrally formed bearing seat 14, and the second positioning wheel 40 is mounted on the bearing seat 14. In this way, the bearing seat 14 is integrally formed directly on the fixed base 10, thereby reducing the manufacturing and assembly of parts and making assembly more convenient.

[0042] The lower side of the fixed base 10 is integrally formed with a sliding groove 15 extending along the length direction of the fixed base 10. The drive slide plate 20 is located in the sliding groove 15. By setting the sliding groove 15, the thickness of the entire side pressure door and window positioning wheel device can be reduced, which facilitates installation and application, and also makes the sliding of the drive slide plate 20 more stable and reliable.

[0043] In use, the side-pressure door and window positioning wheel device of this embodiment is installed on the window sash (sash frame 61); see reference Figure 7 and Figure 10 This is a diagram showing the side-pressure window positioning wheel device in the state when the window sash is closed (at this time, the window sash presses against the window frame 70 in the second direction). Figure 10 It can be seen that at this time, the first positioning wheel 30 is in close contact with the second limiting surface 712 of the wheel groove 71 of the window frame 70. The window sash (sash frame 61) is pressed against the window frame 70 by the squeezing action of the first positioning wheel 30 on the second limiting surface 712 to maintain the seal.

[0044] By rotating the handle 63, the drive slide plate 20 is moved in the first direction. At this time, driven by the drive slide plate 20, the side-moving slide plate 50 and the first positioning wheel 30 mounted on it move in the second direction. During the movement, the first positioning wheel 30 will contact the first limiting surface 711 of the wheel groove 71, and with the reaction force of the first limiting surface 711, the sash frame 61 (window sash) moves in the opposite direction to the second direction. After the first positioning wheel 30 moves into place, the second positioning wheel 40 and the second limiting surface 712 of the wheel groove 71 of the window frame 70 are in close contact. At this time, the window sash is in the open state and can be pushed and pulled left and right.

[0045] In summary, when in the open position, since the first positioning wheel 30 and the second positioning wheel 40 are respectively pressed against the two limiting surfaces of the wheel groove 71, they will not be subject to large shaking due to wind force. During the pushing process, the two sets of positioning wheels are in rolling contact with a pair of limiting surfaces of the wheel groove, making the pushing and pulling process smoother.

[0046] Furthermore, see Figures 7 to 11 When the window sash moves from the open position to the closed position, rotating the handle 63 causes the drive slide plate 20 to move in the opposite direction of the first direction. At this time, driven by the drive slide plate 20, the side-shifting slide plate 50 and the first positioning wheel 30 mounted on it move in the opposite direction of the second direction. During this movement, the first positioning wheel 30 contacts the second limiting surface 712 of the wheel groove 71, and with the reaction force of the second limiting surface 712, the sash frame 61 (window sash) moves in the second direction. After the first positioning wheel 30 is in position, the second positioning wheel 40 and the second limiting surface 712 of the wheel groove 71 of the window frame 70 are in close contact, and the sash frame 61 presses against the window frame 70, at which point the window sash is in the closed state. This ensures the airtightness of the window sash when closed. It should be noted that when the window sash is closed, the second positioning wheel 40 may be in close contact with the first limiting surface 711 of the wheel groove 71, or it may not be in close contact with the first limiting surface 711 of the wheel groove 71. Regardless of the technical solution, it can solve the problem of the window sash easily shaking and generating noise when it is open in the prior art.

[0047] This embodiment also discloses a window sash system and a door sash system. The door sash system and the window sash system have roughly the same structure. Here, the window sash system will be used for further explanation:

[0048] The sash window system includes a sash frame 61, a transmission rod 62, a handle 63, and a connecting block 64; a side-pressure door and window positioning wheel device, wherein the transmission rod 62, handle 63, connecting block 64, and side-pressure door and window positioning wheel device are all installed on the sash frame 61, and the side-pressure door and window positioning wheel device is one of the aforementioned side-pressure door and window positioning wheel devices; wherein:

[0049] The handle 63 is driven by the transmission rod 62, which is connected to the drive slide plate. Thus, the lateral movement of the sash frame 61 is driven by the handle 63. It should be noted that the drive connection between the handle 63 and the transmission rod 62 is conventional technology and will not be elaborated upon here. In practical applications, a window sash system typically has two or more transmission rods 62, and corner brackets 64 are provided at the corners of the sash frame 61 to connect two adjacent transmission rods 62.

[0050] The window sash system typically also includes a window frame 70, which has a wheel groove 71. The two opposing surfaces of the wheel groove 71 are a first limiting surface 711 and a second limiting surface 712. In practical applications, the window and door system (sash frame 61) is equipped with two or more side-pressure window and door positioning wheel devices, thereby improving the operational reliability of the window and door system.

[0051] The key design feature of this invention lies in its use of two sets of positioning pulleys. One set is fixed to a fixed base, and the other is fixed to a side-sliding slide plate. When the window is opened, the side-sliding slide plate moves laterally relative to the fixed base, causing a change in the displacement of the two sets of positioning pulleys. When the window is fully opened, the first positioning wheel presses against the first limiting surface of the frame wheel groove, and the second positioning wheel presses against the second limiting surface of the frame wheel groove. This ensures that the sash will not sway significantly due to wind force when it is in the open position, making the pushing process smoother. Secondly, by simplifying the structure of the window and door positioning wheel device, it has the advantages of simple and ingenious structure, reducing assembly gaps and facilitating installation.

[0052] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
