For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.

Fig. 1, 2 and 9 show an implementation manner of the sliding support 1 of the embodiment of the present application applied to a window (for example, a flat-open window), but it should be noted that fig. 1, 2 and 9 and the following description are only illustrative, and the sliding support 1 of the embodiment of the present application may also be used for building products such as a door (for example, a flat-open door) and the like, so long as the bridge function of the sliding support 1 itself can be achieved, so that the applied building products can be opened and closed, which falls within the protection scope of the embodiment of the present application.

Referring to fig. 1 and 2, an embodiment of the present application provides a slide stay 1 including a chute 10 and a connection assembly 20. When the sliding support 1 of the embodiment of the present application is applied to a door or window, the sliding chute 10 is integrally fixed in the frame slot of the window frame 100, and the connection assembly 20 is connected to the bottom of the window frame body of the window sash 200 in the thickness direction (X direction shown in fig. 3) of the sliding chute 10.

Further, the connecting assembly 20 is a link mechanism, the connecting assembly 20 is rotatably connected to the top of the chute 10 along the thickness direction (X direction shown in fig. 3), and the connecting assembly 20 is entirely parallel to the plane of the chute 10 where the channels are located; meanwhile, a portion of the connection assembly 20 is slidably coupled to the chute 10, that is, the portion is slidably coupled to the chute 10 in a length direction (Y direction shown in fig. 3) of the chute 10. Thus, when the connecting assembly 20 slides in the chute 10, the door and window sash can be rotated relative to the fixed door and window frame, so as to realize the opening and closing of the door and window.

In practical installation, the sliding groove is usually required to be embedded into a frame groove of a profile (such as the window frame 100), so that the requirement on the fitting precision between the sliding groove and the frame groove is high, and if the fitting precision is not achieved, the sliding support cannot be installed or is easy to deform after installation. The structure of the sliding support produced by manufacturers cannot be adapted to various sectional materials, that is, the phenomenon that the sliding groove is not adapted to the frame groove of the sectional materials often occurs in the process of installing the sliding groove on the sectional materials, and the sectional materials are required to be milled in complicated procedures.

Thus, referring to fig. 3 and 4, fig. 3 shows a sectional view of the slide stay 1 according to the embodiment of the present application, and fig. 4 shows a sectional view of the chute 10 of the slide stay according to the embodiment of the present application applied to the window frame 100. Along the thickness direction (X direction shown in fig. 3) of the chute 10, a plurality of convex parts 101 are arranged at the bottom of the chute 10 of the slide stay 1 in the embodiment of the present application, and the plurality of convex parts 101 are arranged at intervals along the length direction (Y direction shown in fig. 3) of the chute 10; the plurality of protrusions 101 are solid structures, in which no through holes are provided, and the plurality of protrusions 101 are configured to abut against the frame groove 110 of the window frame 100 in the thickness direction of the chute 10. That is, when the chute 10 is mounted as described above, the protrusion 101 can be abutted against the bottom of the frame groove 110 of the window frame 100 in the thickness direction (X direction shown in fig. 4) of the chute 10 to support the chute 10 to be erected on the frame groove 110 of the window frame 100 without embedding the chute 10 into the frame groove 110 of the window frame 100.

In fig. 3, six conical protrusions 101 are shown by way of example, but the protrusions 101 in the embodiment of the present application may be also configured in a trapezoid, a rectangle, or other shapes, and seven or eight protrusions 101 may be configured at the same time, and the shape, the number, and the spacing distance between the protrusions 101 in the embodiment of the present application are not limited, so long as they can be closely attached to the bottom of the frame groove 110 of the window frame 100, which belongs to the protection scope of the embodiment of the present application, and may be selected according to practical applications.

Meanwhile, the link members 102 are disposed at intervals along the length direction (Y direction shown in fig. 3) of the chute 10. Illustratively, a connector 102 is provided between the plurality of bosses 101. The connection member 102 is used to connect the frame groove 110 of the window frame 100, and in particular, the connection member 102 can further fix the chute 10 to the frame groove 110 of the window frame 100.

The attachment holes 1021 and screws 1022 are just one implementation of the examples of the present application, and in another possible implementation, the attachment 102 may also be attachment holes 1021 and pins. The connecting piece 102, which can fix the sliding chute 10 and the window frame, is included in the protection scope of the embodiment of the present application.

Illustratively, each boss 101 projects from a connector 102 (e.g., a screw or pin) in the thickness direction (X direction shown in fig. 3).

Referring to fig. 1 to 5, with the above-described technical solution, a plurality of protrusions 101 are provided at the bottom of the sliding chute 10, and the plurality of protrusions 101 can be tightly attached to the bottom wall of the frame slot 110 of a door or window frame (for example, window frame 100), and the sliding chute 10 of the sliding support 1 can be directly fixed to the frame slot 110 of the window frame 100 by cooperating with the connecting members 102 located between the plurality of protrusions 101, instead of embedding the sliding chute 10 into the frame slot 110. Therefore, the notch of the window frame 100 does not need to be milled, so that the installation convenience and the installation efficiency of the sliding support 1 are effectively improved, and the installation cost is reduced; meanwhile, the adaptability of the sliding support 1 and different doors and windows is improved; the strength of the door and window profile is not damaged, so that the danger caused by damage to the door and window is avoided to a certain extent; further, the plurality of protrusions 101 and the connecting piece 102 at the bottom of the chute 10 have a simple structure and low production cost.

The length of the first link 201 is shortest, the length of the second link 202 is a second time, the length of the third link 203 is longer than the first link 201 and the second link 202, and the length of the fourth link 204 is longer than the first link 201 and the second link 202.

Referring to fig. 1 and 9 in combination with fig. 6, a fourth link 204 is connected to the bottom of the window sash 200 in the height direction (Z direction shown in fig. 1) of the window sash 200.

Fig. 9 shows a bottom view of the slide stay 1 applied to the window frame 100 and the window sash 200, and in one possible embodiment, referring to fig. 9, in a height direction (Z direction shown in fig. 1) of the window sash 200, the fourth link 204 is embedded in a frame body at the bottom of the window sash 200, a plurality of mounting holes are formed in the fourth link 204, and the fourth link 204 may be fixed at the bottom of the window sash 200 by screws. The connection manner of the fourth link 204 and the window sash 200 is not limited in the embodiment of the present application, and all that is required is to realize fixation is the protection scope of the embodiment of the present application.
