Description

Technical Field

[0001] The utility model relates to the field of doors and windows, in particular to a door and window ground rail structure for heavy sliding doors. Background Art

[0002] Chinese invention patent announcement number CN108729810B discloses a sliding door and window sash. This common structure includes doors and windows, door and window frames and tracks. The tracks are installed in the door and window frames. Pulleys are arranged on the doors and windows in the tracks and move with the doors and windows. This pulley arrangement structure is convenient for on-site assembly. The installation of the pulleys is completed when the doors and windows are shipped without any additional assembly process. However, since the pulleys are non-modular and destructively embedded in the door and window profiles, the doors and windows need to be laid down for maintenance before they can be disassembled and maintained, which is time-consuming and laborious. In addition, for heavy sliding doors with a large mass, the installation of pulley mechanisms on the doors and windows will further increase the mass of the doors and windows, which in disguise increases the load on the pulleys and the movement resistance of the doors and windows. Utility Model Content

[0016] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. The above description is for the convenience of describing the present utility model and simplifies the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0017] The singular forms "a", "the" and "said" used in the specification include the plural forms unless clearly specified. The terms "comprising", "including" and "containing" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features. The term "and / or" used in the specification includes any and all combinations of one or more of the related listed items.

[0018] In the specification, when it is said that an element is "on", "fixed to", "connected to", "joined to" another element, etc., the element can be directly on, fixed to, connected to, joined to or in contact with the other element, or there may be an intermediate element. In the specification, when a feature is arranged "adjacent" to another feature, it may mean that one feature has a part overlapping with the adjacent feature or a part above or below the adjacent feature.

[0019] It can be understood that although terms such as "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of the concept of this application.

[0020] Exemplary embodiments of this application will be described hereinafter with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals represent the same or functionally identical elements.

[0021] Figure 1 The frame structure of a sliding door is shown, which is composed of a common pair of side frames 11 and a top frame 10 and a bottom frame 20 arranged on the upper and lower sides of the side frames 11. A slide rail mechanism 30 is arranged in the bottom frame 20, and a number of upwardly extending roller members 31 are provided on this slide rail mechanism 30 to support or enable the window sash 40 to move towards the two side frames 11 in the bottom frame 20 with relatively low friction.

[0022] Combined with reference to Figure 2 , the slide rail mechanism 30 mainly consists of a frame 32, a rotating shaft 31b inserted in the middle of the frame 32, and rollers 31a arranged on the rotating shaft 31b to rotate freely around it. It can be understood that the rotating shaft 31b and the rollers 31a constitute the above-mentioned roller members 31. Grooves are arranged in the circumferential direction of the rollers 31a to connect with the convex rails 41 arranged at the bottom of the window sash 40. The roller members 31 are horizontally and fully arranged on the frame 32 so that the window sash 40 can achieve lateral sliding through the rollers 31a. In one embodiment, the rollers 31a are fixed to the rotating shaft 31b, and the rotation of the roller members 31 is achieved by the self-rotation of the rotating shaft 31b. In another embodiment, the rotating shaft 31b is completely fixed and cannot rotate self, and the rotation of the roller members 31 is achieved by bearings arranged between the rollers 31a and the rotating shaft 31b. The advantage of this structure is that the rolling damping of the rolling members 31 is smaller and can bear a heavier window sash 40. The design of embedding the roller members 31 in the frame track can also achieve miniaturization of the volume of the rollers 31a, making the overall design of the whole door and window more beautiful.

[0023] The bottom frame 20 includes a broken-bridge first bottom frame profile 23 and a second bottom frame profile 21. The second bottom frame profile 21 is disposed on one side close to the interior and / or the exterior. The first bottom frame profile 23 is located between two second bottom frame profiles 21 and is fixedly connected to each other through a heat-insulating strip. On the side where the first bottom frame profile 23 and the second bottom frame profile 21 are adjacent to each other, upwardly protruding ribs 21a and 23a are arranged, and a sunken area is formed between the ribs 21a, 23a and the heat-insulating strip. The bottom of the frame 32 has a protruding portion 34 that extends downward and is embedded in the sunken area, so that the frame 32 is clamped on the bottom frame 20. On the other hand, a pair of legs 33 are arranged at the bottom of the frame 32 and are respectively located on both sides of the protruding portion 34. Therefore, with the protruding portion 34 as the middle support structure and the legs 33 as the side support structures, the frame 32 is ensured to be stable. This track arrangement structure moves the rolling elements from the bottom of the common window sash 40 to the bottom frame 20, facilitating the disassembly, assembly and maintenance of the slide rail mechanism 30, and making it beneficial to carry a sliding door with a greater mass.
