Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a combination of folding and sliding doors and windows. Background Technology

[0002] Both traditional sliding doors and traditional folding doors have advantages. Traditional folding doors can fold multiple blades together, taking up less space compared to hinged doors, and the opening size can be flexibly adjusted as needed. Traditional sliding doors mainly rely on pulleys sliding on tracks to open or close, making operation relatively simple; users only need to gently push the blades to open or close the door or window. Furthermore, under normal installation and use, the blades of traditional sliding doors are relatively stable because they are suspended on tracks or slide along floor rails via pulleys. Therefore, this utility model combines the advantages of traditional sliding doors and traditional folding doors, allowing the door or window to be both folding and convertible into a sliding type. Utility Model Content

[0003] The purpose of this utility model is to provide a folding and sliding combination door and window. The door and window can be folding or sliding by means of variable sliding rails and mating hinges, and pulleys.

[0005] The aforementioned docking hinge includes a first hinge plate, which is installed on the side frame of fan blade A. Movable shafts are installed at both ends of the first hinge plate, and return springs are sleeved on the movable shafts. A second hinge plate is installed on the side frame of fan blade B, and a docking hole is provided in the middle of the second hinge plate, which can dock with the movable shaft.

[0006] The variable slide rail includes a first slide rail and a second slide rail. A connecting part is provided on the first slide rail and the second slide rail. The connecting part is provided with two steering rails. The two steering rails are respectively connected to the first slide rail and the second slide rail. A connecting rod is connected between the two steering rails. A vertical rod is connected to the connecting rod. A pull rod is connected to the lower end of the vertical rod. Pushing the pull rod can make the pulley slide from the first slide rail to the second slide rail.

[0007] Furthermore, the first slide rail and the second slide rail have the same structure and are parallel to each other. The connecting part on the first slide rail and the second slide rail is "Y" shaped, and the connecting part can merge the second slide rail into the first slide rail.

[0008] Furthermore, the first hinge plate has bearing seats at both ends, and a cylindrical through hole is provided in the middle of the bearing seat. The movable shaft is installed in the cylindrical through hole and can move in the cylindrical through hole. The movable shafts at both ends are symmetrically distributed along the central axis of the first hinge plate.

[0009] Furthermore, the first hinge plate has a cavity structure, and a transmission rod is installed inside the cavity. One end of the transmission rod is connected to the moving shaft, and the other end is connected to the operating lever. The middle position of the transmission rod is hinged to the inner wall of the first hinge plate.

[0010] Furthermore, the transmission rod is V-shaped as a whole, with a round hole at the corner of the transmission rod, and a cylinder on the inner wall of the first hinge plate. The round hole is connected to the cylinder, and the transmission rod can rotate around the cylinder.

[0011] Furthermore, one end of the reset spring is connected to the movable shaft, and the other end is connected to the cylindrical through hole.

The pulleys are installed within the variable slide rails, and a mating hinge is installed on the side of the fan blades. When the door and window are folding doors, the pulleys installed on fan blades A and B are positioned within the first slide rail. The first hinge on fan blade A is mated with the second hinge on fan blade B, and the mating hinges allow fan blades A and B to be folded. When the door and window are converted into sliding doors, the control lever drives the transmission rod to move the moving shaft out of the mating hole, separating the first hinge on fan blade A from the second hinge on fan blade B. A pull rod then drives the steering rail to engage with the second slide rail and separate it from the first slide rail. This allows the pulley installed on fan blade B to slide along the steering rail into the second slide rail, making the two fan blades misaligned and parallel, achieving the pushing and pulling effect.

[0016] This utility model of doors and windows can be folded like traditional folding doors or pushed and pulled like sliding doors. Furthermore, when opened, the blades can fold or slide along the track to one side, maximizing the opening and increasing the connectivity between indoor and outdoor spaces.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] See Figure 1-5 As shown, a folding and sliding combination door and window includes several sash blades 11. A pulley 14 is installed above the sash blades 11. A variable slide rail 12 is fixedly installed on the balcony wall. The variable slide rail 12 can be converted from a single slide rail to a double slide rail. The pulley 14 is installed inside the variable slide rail 12 and can drive the sash blades 11 to move back and forth on the wall. The pulley 14 and the variable slide rail 12 together provide support for the sash blades 11. A butt hinge 13 is installed on the sash blades 11. The butt hinge 13 can connect two adjacent sash blades 11 and can convert the sash blades 11 from a sliding type to a folding type.

[0028] The aforementioned fan blade 11 has a rectangular structure, consisting of a U-shaped metal frame composed of four borders: top, bottom, left, and right. A glass door panel can be installed in the area enclosed by the U-shaped frame to increase natural light. A pulley 14 is located in the middle of the top border of the fan blade 11. The pulley 14 includes a wheel frame and four rollers installed on both sides of the wheel frame. The pulley 14 can rotate above the fan blade 11. A variable slide rail 12 is installed on the upper edge of the balcony door frame. The variable slide rail 12 is fixedly installed along the length of the upper edge of the door frame. The pulley 14 is installed inside the variable slide rail 12 and can move along the linear direction of the variable slide rail 12.

[0029] Specifically, the variable slide rail 12 includes a first slide rail 21 and a second slide rail 22. The first slide rail 21 and the second slide rail 22 have the same structure and are parallel to each other. A connecting part is provided on the first slide rail 21 and the second slide rail 22. The connecting part is "Y" shaped and can merge the second slide rail 22 into the first slide rail 21. A converter is provided at one end of the first slide rail 21. The converter can control the switching of the variable slide rail 12, so that the pulley 14 slides from the first slide rail 21 to the second slide rail 22. The converter includes two steering rails 23. The steering rails 23 are movable tracks. The head of the steering rails 23 is narrow and gradually tapers. The two steering rails 23 are located inside the slide rail of the connecting part, and the tails of the two steering rails 23 respectively connect to the extension direction of the first slide rail 21 and the second slide rail 22. A connecting rod 24 is connected to the top of the two steering rails 23. The connecting rod 24 is perpendicular to and fixedly connected to the two steering rails 23. The connecting rod 24 can drive the two steering rails 23 to move synchronously. A vertical rod 25 is fixedly connected to the middle position of the connecting rod 24. A pull rod 26 is fixedly connected to the lower end of the vertical rod 25. The pull rod 26 is located below the first slide rail 21 and is perpendicular to the first slide rail 21. A control unit 27 is connected to one end of the pull rod 26. The control unit 27 can drive the pull rod 26 to move along the vertical direction of the first slide rail 21, so that the steering rail 23 engages with the corresponding slide rail. The control unit 27 can also lock the pull rod 26 to prevent the steering rail 23 from moving.

[0030] In the initial state, the pulleys 14 installed on both fan blade A and fan blade B are located within the first slide rail 21 and can move along the first slide rail 21. When the door and window need to be converted into a sliding door, the control unit 27 is pushed, causing the pull rod 26 to drive the steering rail 23 to engage with the second slide rail 22 and separate from the first slide rail 21. At this time, the pulley 14 installed on fan blade B can slide along the steering rail 23 into the second slide rail 22, so that fan blade A and fan blade B are misaligned and parallel, thus enabling the door and window to achieve the sliding effect.

[0031] In addition, a rope can be connected to the pulley 14, and a motor can be installed on the wall. A fixed pulley can be installed on the motor shaft, and the rope can be connected to the fixed pulley. The control motor 27 can be replaced with an electric push rod. When the door needs to be opened or closed, the motor can control the rope to pull the pulley 14 to slide in the variable track, and the electric push rod can control the pull rod 26 to drive the steering rail 23 to move.

[0032] The aforementioned mating hinge 13 includes a first hinge piece 31, which is installed on the side frame of the fan blade A. The first hinge piece 31 has a rectangular structure, and cylindrical bearing seats 32 are mated at its upper and lower ends. Each bearing seat 32 has a circular through hole in the middle, and a movable shaft 33 is installed in the circular through hole. The two movable shafts 33 are symmetrically distributed along the central axis of the first hinge piece 31. The movable shafts 33 can move in the circular through hole. A return spring 34 is sleeved on the movable shaft 33. One end of the return spring 34 is connected to the movable shaft 33, and the other end is connected to the circular through hole. The return spring 34 can cause the pressed movable shaft 33 to spring back to its initial position. A second hinge piece 35 is installed on the side frame of the fan blade B. The installation position of the second hinge piece 35 corresponds to that of the first hinge piece 31. A mating hole 36 is provided in the middle of the second hinge piece 35. The mating hole 36 is a circular hole and matches the movable shaft 33.

[0033] When a door or window needs to be converted into a folding door, the pulleys 14 installed on blades A and B need to be positioned within the first slide rail 21, and the first hinge 31 on blade A and the second hinge 35 on blade B need to be aligned. During alignment, the alignment hole 36 presses the moving shaft 33 to both sides. After the alignment hole 36 passes through the moving shaft 33, the return spring 34 drives the moving shaft 33 to rebound, causing the moving shaft 33 to lock in the alignment hole 36, and enabling the first hinge 31 and the second hinge 35 to align. At this time, under the action of the alignment hinge 13, blades A and B can be folded. Similarly, multiple blades 11 can be aligned. It should be noted that during the folding process of blades 11, the pulley 14 can rotate a certain angle above the blades 11 to ensure the normal sliding of the slider within the first slide rail 21.

[0034] To achieve the separation of fan blade A and fan blade B, the first hinge plate 31 is designed as a cavity structure and is connected to a cylindrical through hole. Two transmission rods 37 are installed inside the first hinge plate 31. The transmission rods 37 are V-shaped. One end of the transmission rod 37 is fixedly connected to the moving shaft 33, and the other end is vertically fixedly connected to the control lever 39. The top of the control lever 39 is located at the door handle, and the door handle is a hidden door handle to prevent interference when pushing and pulling between the fan blades 11. A round hole is provided at the corner of the transmission rod 37. A cylinder 38 is provided on the inner wall of the first hinge plate 31. The round hole is connected to the cylinder 38, and the transmission rod 37 can rotate around the cylinder 38.

[0035] See Figure 7 As shown, when the control lever 39 is pushed to the right, the control lever 39 applies a rightward thrust to the two transmission rods 37, causing the transmission rods 37 to rotate around their respective corners and lift the two moving shafts 33 in opposite directions. At this time, the moving shafts 33 are moved out of the docking hole 36, which can realize the separation of the first hinge plate 31 and the second hinge plate 35, thereby realizing the separation of the fan blade 11A and the fan blade 11B.

[0036] In addition, to ensure the airtightness and stability of the doors and windows, sealing strips are installed between the edges of the sash blades 11. These sealing strips effectively prevent the penetration of air and rainwater.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
