[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0043] The present utility model will be further described in detail below with reference to the drawings.

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 , this embodiment discloses a drift door and window system, including a door and window frame, a movable door and window sash 2, a load-bearing wheel assembly 4 and a guide wheel assembly 5; the door and window frame includes an upper track 1 and a lower track 6 arranged oppositely up and down; the load-bearing wheel assembly 4 includes a first sliding seat 41 and a first swing arm 42, the first sliding seat 41 is slidably connected to the upper track 1, and the first swing arm 42 is rotatably connected to the first sliding seat 41 and rotatably connected to the upper side of the movable door and window sash 2; the guide wheel assembly 5 is slidably connected in the lower track 6 and rotatably connected to the lower side of the movable door and window sash 2; under the guidance of the load-bearing wheel assembly 4 and the guide wheel assembly 5, the movable door and window sash 2 can be moved out or into the door and window frame in the first direction, and the movable door and window sash 2 can be translated relative to the door and window frame along the second direction after moving out of the door and window frame. The first direction is the thickness direction of the movable door and window sash 2, and the second direction is the extending direction of the upper track 1.

[0045] Specifically, the first direction can refer to the e1 direction in Figure 3 , and the second direction can refer to the e2 direction in Figure 3 .

[0046] Specifically, in this embodiment, the first swing arm 42 can move between a retracted state and an extended state relative to the first sliding seat 41; as shown in Figure 1 , Figure 6 and Figure 8 , when the first swing arm 42 rotates to the retracted state, the movable door and window sash 2 moves into the door and window frame; as shown in Figure 2 , Figure 7 and Figure 9As shown, when the first swing arm 42 rotates to the unfolded state, the movable door and window sash 2 moves out of the door and window frame, and the movable door and window sash 2 can translate relative to the door and window frame along the second direction outside the door and window frame.

[0047] In a drift door and window system provided in this embodiment, the load-bearing wheel assembly 4 bears the main weight of the movable door and window sash 2 and guides the movement of the movable door and window sash 2. The guide wheel assembly 5 is used to provide guidance for the movement of the movable door and window sash 2. The load-bearing wheel assembly 4 is arranged on the upper track 1 and the upper side of the movable door and window sash 2. Compared with the prior art drift door and window system with lower load-bearing, the load-bearing wheel assembly 4 and the upper track 1 are not prone to dust accumulation, water accumulation and accumulation of other sundries. The movement of the load-bearing wheel assembly 4 will not be interfered. Also, there is no need to increase the width of the upper track 1 for convenient cleaning. The upper track 1 can be made narrower and lighter, so that the entire drift door and window system can also be made narrower and lighter. Therefore, this drift door and window system can meet the requirements for a drift door and window system that is narrower, lighter, not prone to dust accumulation, not prone to water accumulation and not prone to accumulation of other sundries in some application environments.

[0048] Specifically, the drift door and window system provided in this embodiment is applicable to shower rooms. The drift door and window system applied in shower rooms needs to meet the requirements of being narrower, lighter, not prone to dust accumulation, not prone to water accumulation and not prone to accumulation of other sundries.

[0049] It should be noted that in the drift door and window system of this embodiment, the load-bearing wheel assembly 4 is arranged on the upper track 1. Compared with the prior art drift door and window system with lower load-bearing, the airtightness, wind resistance and movement stability of the drift door and window system of this embodiment are relatively not high. However, it can be understood that the shower room is located indoors, and its requirements for the airtightness, wind resistance and movement stability of the door and window system are also relatively not high. The drift door and window system of this embodiment can be applied to indoor application environments such as shower rooms.

[0050] Such as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 11As shown in the figure, specifically, in this embodiment, the upper track 1 is provided with an upper sliding groove 11. The upper sliding groove 11 includes a sliding bottom wall 111 and two relatively arranged sliding side walls 112. The two sliding side walls 112 are vertically connected to both sides of the sliding bottom wall 111 respectively. The first sliding seat 41 is slidably connected to the sliding bottom wall 111, and a through groove 113 extending in the second direction is formed in one of the sliding side walls 112. The first swing arm 42 extends out from the through groove 113 to be rotatably connected to the upper side of the movable door and window sash 2. In this way, on the one hand, the first sliding seat 41 is slidably connected to the sliding bottom wall 111, and the sliding bottom wall 111 is used to stably support the first sliding seat 41, so that the load-bearing wheel assembly 4 can stably bear the weight of the movable door and window sash 2 and guide the movement of the movable door and window sash 2. On the other hand, by providing the through groove 113, the first swing arm 42 can move in the through groove 113 to guide the movement of the movable door and window sash 2, which can avoid the interference of the upper track 1 on the installation and movement of the first swing arm 42, and can also avoid the installation and movement of the first swing arm 42 affecting the sliding fit between the first sliding seat 41 and the sliding bottom wall 111. On the other hand, the overall structure of the first swing arm 42, the first sliding seat 41 and the upper sliding groove 11 is relatively simple and occupies less space, so that the upper track 1 can meet the requirements of being narrow and light.

[0051] As Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown in the figure, specifically, in this embodiment, the upper sliding groove 11 further includes a groove upper wall 114. The groove upper wall 114 is connected between the two sliding side walls 112 and is opposite to the sliding bottom wall 111. The groove upper wall 114 can block the internal space of the upper sliding groove 11 to provide a protective effect, avoiding water, dust and other sundries from entering the upper sliding groove 11.

[0052] It should be noted that, in some other embodiments, the through groove 113 can also be opened on the sliding bottom wall 111 in the second direction, and it can be selected according to actual needs, and it is not uniquely limited here.

[0053] As Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, preferably, in this embodiment, in order to enable the first sliding seat 41 to slide smoothly and continuously, the load-bearing wheel assembly 4 further includes a first pulley 43. The first pulley 43 is rotatably connected to the first sliding seat 41 through a first rotating shaft 431. The axial direction of the first rotating shaft 431 is arranged horizontally. The first pulley 43 is in rolling connection with the sliding bottom wall 111. More preferably, in this embodiment, the sliding bottom wall 111 is provided with a guiding rib 115 extending in the second direction. The first pulley 43 is in rolling connection with the guiding rib 115. The rolling cooperation between the first pulley 43 and the guiding rib 115 can provide stable guiding and support for the movement of the movable door and window sash 2.

[0054] As Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, preferably, in this embodiment, the load-bearing wheel assembly 4 further includes a second pulley 44. The second pulley 44 is rotatably connected to the first sliding seat 41 through a second rotating shaft 441. The axial direction of the second rotating shaft 441 is arranged vertically. Both sides of the second pulley 44 can respectively form rolling contacts with the two sliding side walls 112. In this way, the sliding stability of the first sliding seat 41 in the upper sliding groove 11 can be further improved, thereby preventing the first sliding seat 41 from shaking and affecting the movement stability of the movable door and window sash 2.

[0055] As Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, specifically, in this embodiment, the drift door and window system further includes a fixed door and window sash 3. The fixed door and window sash 3 is fixed within the door and window frame. The fixed door and window sash 3 has a first vertical side frame 31, and the movable door and window sash 2 has a second vertical side frame 23. Preferably, in this embodiment, the drift door and window system further includes a first sealing strip 7 and a second sealing strip 8. The first sealing strip 7 is vertically arranged on the first vertical side frame 31, and the second sealing strip 8 is vertically arranged on the second vertical side frame 23. When the movable door and window sash 2 is moved into the door and window frame, the fixed door and window sash 3 and the movable door and window sash 2 are arranged side by side in the second direction to jointly close the door. The first sealing strip 7 and the second sealing strip 8 are abutted against each other to form a seal, thereby improving the sealing performance at the junction of the fixed door and window sash 3 and the movable door and window sash 2 when closing the door.

[0056] As Figure 3 , Figure 4 and Figure 5As shown, preferably, in this embodiment, the first sealing strip 7 has a first vertical side wall 71 and a second vertical side wall 72 that are spaced apart. The second sealing strip 8 has a third vertical side wall 81 and a fourth vertical side wall 82 that are spaced apart. When the movable window sash 2 is moved into the window frame, the first vertical side wall 71 abuts against the third vertical side wall 81, and the second vertical side wall 72 abuts against the fourth vertical side wall 82. With such a setting, a double seal is formed to further improve the sealing performance at the junction of the fixed window sash 3 and the movable window sash 2 when the door is closed.

[0057] As Figure 3 , Figure 4 and Figure 5 shown, specifically, in this embodiment, a first arc-shaped side wall 73 is connected between the first vertical side wall 71 and the second vertical side wall 72, and the first arc-shaped side wall 73 is concave.

[0058] As Figure 3 , Figure 4 and Figure 5 shown, specifically, in this embodiment, a second arc-shaped side wall 83 is connected between the third vertical side wall 81 and the fourth vertical side wall 82, and the second arc-shaped side wall 83 is concave.

[0059] As Figure 3 , Figure 4 and Figure 5 shown, specifically, in this embodiment, the first vertical frame 31 is provided with a first insertion groove 311, and the first sealing strip 7 is provided with a first insertion portion 74. The first insertion portion 74 is inserted into the first insertion groove 311 to fix the first sealing strip 7 to the first vertical frame 31.

[0060] As Figure 3 , Figure 4 and Figure 5 shown, specifically, in this embodiment, the second vertical frame 23 is provided with a second insertion groove 231, and the second sealing strip 8 is provided with a second insertion portion 84. The second insertion portion 84 is inserted into the second insertion groove 231 to fix the second sealing strip 8 to the second vertical frame 23.

[0061] As Figure 12 , Figure 13 , Figure 14 and Figure 15 shown, preferably, in this embodiment, the lower track 6 is provided with a downward-opening lower chute 61, and the lower chute 61 has a chute top wall 611. In this way, the accumulation of dust, water, and other sundries in the lower track 6 can be reduced. Specifically, the guide wheel assembly 5 includes a second sliding seat 51 and a second swing arm 52. The second sliding seat 51 is slidably connected to the lower chute 61, and the second swing arm 52 is rotatably connected to the second sliding seat 51 and rotatably connected to the lower side of the movable window sash 2.

[0062] Specifically, in this embodiment, the second swing arm 52 can move relative to the second sliding seat 51 between a retracted state and an extended state; as Figure 1 , Figure 12 and Figure 14 shown, when the second swing arm 52 rotates to the retracted state, the movable window and door sash 2 moves into the window and door frame; as Figure 1 and Figure 13 shown, when the second swing arm 52 rotates to the extended state, the movable window and door sash 2 moves out of the window and door frame, and the movable window and door sash 2 can translate relative to the window and door frame along the second direction outside the window and door frame.

[0063] As Figure 12 , Figure 13 , Figure 14 , Figure 16 , Figure 17 , Figure 18 and Figure 19 shown, further, in this embodiment, the second swing arm 52 includes a first connecting arm 521, a second connecting arm 522, and a third connecting arm 523 that are connected in sequence. The first connecting arm 521 is rotatably connected to the second sliding seat 51, and the third connecting arm 523 is rotatably connected to the lower side of the movable window and door sash 2. The first connecting arm 521 and the third connecting arm 523 are located on the side of the second connecting arm 522 close to the second sliding seat 51. An avoidance space 524 is formed between the first connecting arm 521, the second connecting arm 522, and the third connecting arm 523. When the movable window and door sash 2 moves into the window and door frame, a part of the lower track 6 is located in the avoidance space 524. With such a setting, the first connecting arm 521 and the third connecting arm 523 are distributed vertically to form an avoidance space 524 between the first connecting arm 521, the second connecting arm 522, and the third connecting arm 523. The setting of the avoidance space 524 enables the installation and movement of the second swing arm 52 to avoid the self-frame structure of the lower track 6. The lower track 6 and the movable window and door sash 2 do not need to increase the thickness dimension due to providing a large space for the installation and movement of the swing arm. The thickness dimensions of the lower track 6 and the movable window and door sash 2 are allowed to become smaller. Thus, the guide wheel assembly 5 can be applied to a drift window and door system with a smaller thickness dimension.

[0064] As Figure 16 , Figure 17 and Figure 18 shown, preferably, in this embodiment, in order to facilitate the installation of the guide wheel assembly 5 between the lower track 6 and the lower side of the movable window and door sash 2, the third connecting arm 523 is located above the first connecting arm 521.

[0065] Specifically, in this embodiment, in order to save production costs and improve the overall structural strength, the first connecting arm 521, the second connecting arm 522, and the third connecting arm 523 are integrally formed.

[0066] As Figure 16 ,Figure 17 , Figure 18 and Figure 19 As shown in Figure 18 and Figure 19 , preferably, in this embodiment, both the first connecting arm 521 and the third connecting arm 523 are horizontally arranged, and the second connecting arm 522 extends along a direction inclined to the horizontal plane. In this way, on the one hand, it is convenient for the first connecting arm 521 to be rotatably connected to the second sliding seat 51 and for the third connecting arm 523 to be rotatably connected to the movable door and window sash 2. On the other hand, it can also improve the overall installation stability and movement stability of the second swing arm 52.

[0067] As Figure 14 and Figure 16 As shown in Figure 14 and Figure 16 , preferably, in this embodiment, the guide wheel assembly 5 further includes a third pulley 53. The third pulley 53 is rotatably connected to the second sliding seat 51 through a third rotating shaft 531. The axial direction of the third rotating shaft 531 is arranged vertically. The lower chute 61 further includes two limiting side walls 612. The two limiting side walls 612 are respectively connected to both sides of the chute top wall 611.
