Description

Technical Field

[0001] The invention relates to the field of doors and windows, and in particular to a side-pressure door and window positioning wheel device and a door and window system. Background Art

[0002] like Figure 1 and Figure 2 As shown, in order to facilitate the installation of window sashes, there is a certain gap between the positioning wheel of the traditional positioning wheel device and the wheel groove of the profile; this will cause the sash to swing to a large displacement when in the open position, and the window sash is prone to shaking noise under the action of wind. During the push and pull process, it is not smooth enough and will produce shaking noise. Specifically, the existing door and window side shift module is usually set up by providing a positioning wheel on the side shift module, and the lateral movement of the window sash / door sash is achieved through the positioning wheel. However, in the open position, the two limiting surfaces of the positioning wheel and the wheel groove maintain a large gap; the window sash / door sash is easily affected by wind in the open position, resulting in shaking noise; when pushed and pulled, it is not smooth enough and the use effect is poor; secondly, since the existing side shift module has many assembled parts, there will be accumulated assembly gaps between the parts, and the superposition of various gaps will also lead to poor positioning effect of the positioning wheel.

[0003] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the invention

[0004] In order to solve the defects and shortcomings of the above-mentioned prior art, the present invention provides a side-pressure door and window positioning wheel device and a door and window system, which are provided with two groups of positioning pulleys, one group is fixed on a fixed base, and the other group is fixed on a side-shifting slide. When the window is in the process of opening, the side-shifting slide is laterally translated relative to the fixed base, so that the displacement of the two groups of positioning pulleys changes. When the opening is completed, 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, thereby ensuring that the door and window will not shake greatly due to the action of wind when in the open position, and the pushing process is smoother; secondly, by simplifying the structure of the door and window positioning wheel device, the assembly gap is reduced and the installation is also convenient.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A side pressure door and window positioning wheel device comprises a fixed base, a driving slide plate, a first positioning wheel, a second positioning wheel, and a side shifting slide plate, wherein the driving slide plate is located at the lower side of the fixed base, and the first positioning wheel, the second positioning wheel, and the side shifting slide plate are all located at the upper side of the fixed base; the first positioning wheel is mounted on the side shifting slide plate, and the second positioning wheel is mounted on the fixed base, and the driving slide plate is used to drive the side shifting slide plate to move laterally along the front-rear direction, wherein:

[0007] The driving slide has a first driving part, the side shifting slide has a second driving part matched with the first driving part, and the fixed base is provided with a limiting mechanism for limiting the side shifting slide to move in the left and right directions.

[0008] As a preferred solution, the limiting mechanism includes a lateral displacement groove arranged on the upper side of the fixed base, and the lateral displacement groove extends along the front-rear direction.

[0009] As a preferred solution, the first driving part is a driving groove, the second driving part is a first positioning wheel axle installed on the side-shifting slide plate, the first positioning wheel axle passes through the side-shifting slide block in the up and down directions, the first positioning wheel axle is installed on the upper end of the first positioning wheel axle, and the lower end of the first positioning wheel axle is located in the driving groove.

[0010] As a preferred solution, the first driving part is a pushing column arranged on the driving slide, the second driving part is a driving groove arranged on the side-shifting slide, and the pushing column is at least partially located in the driving groove so that the pushing column can push the side-shifting slide to move sideways.

[0011] As a preferred solution, the first positioning wheel is mounted on the upper end of the first positioning wheel shaft, and a lateral shift locking point is mounted on the lower end of the first positioning wheel shaft, and the lateral shift locking point is located in the driving groove.

[0012] As a preferred solution, the fixed base is integrally formed with a shaft seat, and the second positioning wheel is mounted on the shaft seat.

[0013] As a preferred solution, a slide groove extending along the length direction of the fixed base is integrally formed on the lower side surface of the fixed base, and the driving slide plate is located in the slide groove.

[0016] A door and window system, comprising a sash frame, a transmission rod, a handle, a connecting block, and a side-pressure door and window positioning wheel device, wherein the transmission rod, the handle, the connecting block, and the side-pressure door and window positioning wheel device are all installed on the sash frame, and the side-pressure door and window positioning wheel device is a signed side-pressure door and window positioning wheel device; wherein:

[0017] The handle is drivingly connected to the transmission rod, and the transmission rod is connected to the driving slide.

[0018] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that it is mainly achieved by providing two groups of positioning pulleys, one group is fixed on a fixed base, and the other group is fixed on a side-shifting slide. When the window is opening, the side-shifting slide is laterally translated relative to the fixed base, so that the displacement of the two groups of positioning pulleys changes. When the opening is completed, 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, thereby ensuring that the door sash will not shake greatly due to the action of wind when in the open position, and is smoother during the pushing process. Secondly, by simplifying the structure of the door and window positioning wheel device, it has the advantages of simple and ingenious structure, reduces the assembly gap, and facilitates installation.

DETAILED DESCRIPTION

[0033] The technical solution in this embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiment is only a preferred embodiment of the present invention.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] See attached Figures 1 to 11 In an embodiment of the present invention, a side pressure door and window positioning wheel device and a door and window system include a fixed base 10, a driving slide 20, a first positioning wheel 30, a second positioning wheel 40, and a side shifting slider 50. The driving slide 20 is located at the lower side of the fixed base 10, and the first positioning wheel 30, the second positioning wheel 40, and the side shifting slider 50 are all located at the upper side of the fixed base 10; the first positioning wheel 30 is installed on the side shifting slider 50, and the second positioning wheel 40 is installed on the fixed base 10. The driving slide 20 is used to drive the side shifting slider 50 to move sideways along the front-rear direction, wherein:

[0037] The driving slide plate 20 is provided with a first driving part, the side shifting slide plate 50 is provided with a second driving part adapted to the first driving part, and a limiting mechanism for restricting the side shifting slide plate 50 from moving in the left-right direction is arranged on the fixed base 10. The driving slide plate 20 is used for connecting a transmission rod 62 of a window sash system or a door sash system. The first positioning wheel 30 is used for pushing the window sash or the door sash to achieve lateral movement, so as to achieve locking and pressing or unlocking and being pushable; the extending direction of the driving groove 21 is not completely parallel to the length direction of the driving slide plate 20. For example, in this embodiment, the driving groove 21 is a curve. In other embodiments, the driving groove 21 may also be an oblique line, which is not specifically limited herein, as long as it can satisfy the lateral movement of the side shifting slide plate 50.

[0038] Specifically: The limiting mechanism includes a side shifting groove 11 arranged on the upper side of the fixed base 10, and the side shifting groove 11 extends in the front-rear direction; the first driving part is a driving groove 21 arranged on the driving slide plate 20, the second driving part is a first positioning wheel shaft 31 installed on the side shifting slide plate 50, the first positioning wheel shaft 31 passes through the side shifting slider 50 in the up-down direction, the upper end of the first positioning wheel shaft 31 is installed with the first positioning wheel 30, and the lower end of the first positioning wheel shaft 31 is located in the driving groove 21. It can be added that the lateral movement described in this specification is the movement in the front-rear direction in the drawings. The limiting mechanism may also be limiting blocks arranged on the left side and the right side of the side shifting slide plate 50 to restrict the left-right movement of the side shifting slide plate 50; or, a limiting protrusion for restricting the side shifting slide plate 50 from moving in the left-right direction is directly integrally formed on the fixed base 10; of course, the limiting mechanism may also be a limiting cover plate covering the upper side of the side shifting slide plate 50, and the limiting cover plate is arranged in an approximate shape of "冖"; there is an active gap between the lower side of the limiting cover plate and the upper side of the side shifting slide plate 50, and limiting ribs for limiting the left-right movement of the side shifting slide plate 50 extend downward from the left side and the right side of the limiting cover plate; the limiting mechanism may also be other structures or forms, which are not specifically limited herein. In this embodiment, there are also two pressing plates 12 for preventing the side shifting slider 50 from slipping out upward. The two pressing plates 12 are arranged oppositely above the groove 13 of the fixed base 10, so as to form the aforementioned side shifting groove 11; in this way, not only is it very convenient during installation, but also it is not complicated to disassemble and assemble during subsequent maintenance and replacement. A limiting protrusion 111 is also arranged on one side of the side shifting groove 11 to prevent the side shifting slider 50 from slipping out. Of course, the side shifting groove 11 may also be an integrally formed T-shaped groove or dovetail groove, so that the setting of the pressing plate 12 can be omitted. Of course, it may also be other shapes.

[0039] The first positioning wheel 30 is installed on the upper end of the first positioning wheel shaft 31, and a lateral shift locking point 32 is installed at the lower end of the first positioning wheel shaft 31, and the lateral shift locking point 32 is located in the driving groove 21; the lateral shift locking point 32 can be a guide wheel, and through the setting of the guide wheel, the process of the driving skateboard 20 pushing the first positioning wheel 30 is smoother.

[0040] It can be supplemented here that: in other embodiments, the driving groove 21 can also be set on the side-shifting slide 50, and a pushing column adapted to the driving groove 21 is provided on the driving slide 20, and the pushing column is at least partially located in the driving groove 21. The specific shape of the driving groove 21 can be the same as the aforementioned driving groove 21. The lateral movement of the side-shifting slide 50 is achieved by moving the pushing column on the driving slide 20 in the driving groove 21. This is a transformation setting of the conventional driving structure of those skilled in the art and will not be elaborated here.

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

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

[0043] When in use, the side pressure door and window positioning wheel device of this embodiment is installed on the window sash (sash frame 61); Figure 7 and Fig.10 , is a state diagram of the side pressure door and window positioning wheel device when the window sash is closed (at this time, the window sash presses the window frame 70 toward the second direction), Fig.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, and the squeezing effect of the first positioning wheel 30 on the second limiting surface 712 is used to achieve the compression of the window sash (sash frame 61) on the window frame 70 to maintain the sealing.

[0044] By rotating the handle 63, the rotation of the handle 63 is utilized to drive the driving slide 20 to move in the first direction. At this time, driven by the driving slide 20, the side shift slide 50 and the first positioning wheel 30 mounted thereon 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 help of the reaction force of the first limiting surface 711, the sash frame 61 (window sash) moves in the direction opposite 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 an open state and is in the open position. The window sash 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 correspondingly support the two limiting surfaces of the wheel groove 71, there will be no large shaking due to the action of wind. During the pushing process, the two sets of positioning wheels are in rolling contact with a pair of limiting surfaces of the wheel groove, and pushing and pulling are also smoother.

[0046] For further information, see Figures 7 to 11 When the window sash moves from the open position to the closed position, the handle 63 is rotated, and the driving slide 20 is driven to move in the opposite direction of the first direction by the rotation of the handle 63. At this time, driven by the driving slide 20, the side shifting slide 50 and the first positioning wheel 30 installed thereon move in the opposite direction of the second direction. During the movement, the first positioning wheel 30 will contact 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 direction of 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, and the sash frame 61 presses the window frame 70, and the window sash is in the closed state. In this way, the sealing of the window sash when closed can be ensured. It should be noted that when the window sash is in the closed state, the second positioning wheel 40 may be in close contact with the first limiting surface 711 of the wheel groove 71, or may be in loose contact with the first limiting surface 711 of the wheel groove 71. Regardless of which technical solution is used, it can solve the problem in the prior art that the window sash is prone to shaking and generating noise in the open position.

[0047] This embodiment also discloses a window leaf system and a door leaf system. The structures of the door leaf system and the window leaf system are substantially the same. Here, the window leaf system is used for further description:

[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, the handle 63, the connecting block 64, and the 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 the aforementioned side-pressure door and window positioning wheel device; wherein:

[0049] The handle 63 is connected to the transmission rod 62, and the transmission rod 62 is connected to the driving slide, so that the sash frame 61 is driven to move sideways through the handle 63. It can be added that the driving connection between the handle 63 and the transmission rod 62 is a conventional technology and is not described in detail here. In specific applications, there are more than two transmission rods 62 in a window sash system, and a corner turner 64 is provided at the corner of the sash frame 61 to connect two adjacent transmission rods 62.

[0050] The window sash system generally further includes a window frame 70, the window frame 70 having a wheel groove 71, and two opposite surfaces of the wheel groove 71 are respectively a first limiting surface 711 and a second limiting surface 712. In practical applications, more than two side-pressure door and window positioning wheel devices are installed on the door and window system (sash frame 61), thereby improving the working reliability of the door and window system.

[0051] The design focus of the present invention is that it is mainly through the provision of two groups of positioning pulleys, one group is fixed on the fixed base, and the other group is fixed on the side-shifting slide. When the window is in the process of opening, the side-shifting slide is laterally translated relative to the fixed base, so that the displacement of the two groups of positioning pulleys changes. When the opening is completed, 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, thereby ensuring that when the window is in the open position, it will not cause a large shake due to the action of wind force, and it is smoother during the pushing process; secondly, by simplifying the structure of the door and window positioning wheel device, it has the advantages of simple and ingenious structure, reduces the assembly gap, and facilitates installation.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
