Abstract
Description
Technical Field
[0001] This invention relates to a window frame track, in particular to a flat window frame track. Prior Art
[0002] Conventional flat windows typically consist of a window frame and at least one sash. The sash moves within the frame along guide rails. When the sash is open, the guide rails are exposed. However, when flat windows are used in floor-to-ceiling windows, doors, or other structures, where users pass over them, the grooves in the frame guide rails can cause users to fall or make it difficult to maneuver in a wheelchair, endangering their safety.
[0003] In view of this, proposing a better improvement solution is an urgent problem to be solved in this industry. Summary of the Invention
[0004] The main purpose of this invention is to propose a flat window frame track, which is used to solve the problem that when a flat window is opened, the guide rail in the window frame will be exposed, which may cause the user to fall or make it difficult to push the wheelchair.
[0005] To achieve the above-mentioned purpose, the present invention proposes a planar window frame track, which is used to move a window sash in the planar window frame track, and the window sash has a guide rod; the planar window frame track has: A window frame, wherein the guide rod of the window sash can move within the window frame; A cover body is disposed in the window frame so as to be movable up and down; A linkage device is provided in the window frame and has: A base is provided on the window frame, and the cover is provided on the base so as to be movable up and down; An actuating plate is pivotally mounted on the base and comprises: Two push rods are provided on the actuating plate, and the two push rods are respectively located on both sides of the actuating plate; a linkage rod, which is disposed on the actuating plate and connected to the cover body, and drives the cover body up and down as the actuating plate pivots; When the window sash moves in the window frame to open, the guide rod of the window sash pushes one of the push rods to rotate the actuating plate, thereby driving the linkage rod to rotate, and allowing the cover to move upward until the top surface of the cover is flush with the top surface of the window frame; when the window sash moves in the window frame to close, the guide rod of the window sash pushes the other push rod to rotate the actuating plate in the opposite direction, thereby driving the linkage rod to rotate in the opposite direction, and allowing the cover to descend below the top surface of the window frame.
[0006] As described above, the flat window frame track, wherein the actuating plate is fan-shaped and has: When the window sash moves in the window frame until it is opened and the actuating plate rotates, one of the side edges of the actuating plate can abut against the base; when the window sash moves in the window frame until it is closed and the actuating plate rotates in the opposite direction, the other side edge of the actuating plate can abut against the base.
[0007] As described above, the planar window frame track, wherein the angle between the two side edges of the actuating plate is 90 degrees to 120 degrees.
[0008] In the aforementioned planar window frame track, the two push rods are located on one side of the actuating plate away from the cover body, and the connecting rod is located on the other side of the actuating plate opposite to the two push rods.
[0009] The flat window frame track as described above, wherein the base has: A supporting portion has a top surface flush with the top surface of the window frame, and the actuating plate is pivotally arranged on the supporting portion.
[0010] As described above, the flat window frame track, wherein the linkage device further has: A plurality of linkage plates are arranged at intervals along the extension direction of the cover body and rotate with the actuating plate, and each linkage plate has: a first end pivotally mounted on the base; A second end is the other end of the linkage plate relative to the first end and is pivotally mounted on the cover.
[0011] As described above, the flat window frame track, wherein the linkage device has: An elastic member is connected to the actuating plate and enables the actuating plate to rotate toward two opposite sides.
[0012] The above-mentioned flat window frame track further has: A sealing member is located on the window frame and is tightly fitted with the window sash and the window frame when the window sash is closed.
[0013] The advantage of this invention lies in the fact that, by pivoting an actuating plate on the base, as the window sash moves within the window frame to open, it pushes the actuating plate, causing it to rotate. This in turn pushes the cover upward until its top surface is flush with the top surface of the window frame. This prevents users from tripping over uneven flat window frame tracks, or wheelchairs from getting stuck in the flat window frame tracks. Simple diagram description

Implementation Method
[0015] Please refer to Figures 1 and 7. This invention proposes a planar window frame track for moving a window sash A within the planar window frame track. Window sash A has a guide rod A1. The planar window frame track comprises a window frame 10, a cover 20, a linkage device 30, and optionally a seal 40.
[0016] Please refer to Figures 1 and 2. The guide rod A1 of window sash A is movable within the window frame 10. In this embodiment, the window frame 10 has a first guide rail 11 and a second guide rail 12, which are parallel to each other. When window sash A is closed, it rests on the first guide rail 11. When window sash A is opened, it moves from the first guide rail 11 to the second guide rail 12 and along the second guide rail 12 until it is fully opened. In other embodiments, window sash A may move only along the first guide rail 11, while the guide rod A1 of window sash A is extended to the second guide rail 12. This allows the guide rod A1 of window sash A to also move along the second guide rail 12 while the window sash A moves within the first guide rail 11.
[0017] Please refer to Figures 3 and 7. The cover 20 is vertically movable within the window frame 10. When the cover 20 moves upward, its top surface can be flush with the top surface of the window frame 10. In this embodiment, the cover 20 is mounted within the first guide rail 11. The vertical movement of the cover 20 is not limited to vertical movement but also includes arcuate movement, as long as it can achieve a change in height. The linkage device 30 is mounted within the window frame 10 and comprises a base 31, an actuating plate 32, a plurality of linkage plates 33, and an elastic member 34.
[0018] Refer to Figure 7. A base 31 is disposed within the window frame 10, and the cover 20 is disposed on the base 31 so as to be movable up and down. In this embodiment, the base 31 has a support portion 311 that separates the first guide rail 11 from the second guide rail 12. The top surface of the support portion 311 is flush with the top surface of the window frame 10.
[0019] Please refer to Figures 5 and 6. The actuating plate 32 is pivotally mounted on the support portion 311 of the base 31 and is fan-shaped. In other embodiments, the shape of the actuating plate 32 is not limited to this. The actuating plate 32 can also be triangular or circular, as long as it can pivot on the base 31. The actuating plate 32 has two sides 321, two push rods 322, and a linkage rod 323. When the window sash A moves within the window frame 10 until the window sash A opens and the actuating plate 32 rotates, one side 321 of the actuating plate 32 abuts against the base 31, restricting further rotation of the actuating plate 32. When the window sash A moves within the window frame 10 until the window sash A closes and the actuating plate 32 rotates in the opposite direction, the other side 321 of the actuating plate 32 abuts against the base 31, restricting further rotation of the actuating plate 32. In this embodiment, the angle between the two sides of the actuating plate is between 90 and 120 degrees.
[0020] Please refer to Figures 5 to 8 . The push rods 322 are disposed on the actuating plate 32 , with the two push rods 322 located on either side of the actuating plate 32 . In other words, the two push rods 322 are adjacent to the two side edges 321 of the actuating plate 32 . In this embodiment, the push rods 322 are located on the side of the actuating plate 32 away from the cover 20 and extend toward the second guide rail 12 . Therefore, when the guide rod A1 of the window sash A moves along the second guide rail 12 , the push rods 322 are pushed. In other embodiments, the position of the push rods 322 is not limited to being located on the side of the actuating plate 32 away from the cover 20 ; they may also be located on the top surface (top side) of the actuating plate 32 , as long as the guide rod A1 of the window sash A moves along the second guide rail 12 to push the push rods 322 .
[0021] The linkage rod 323 is disposed on the actuating plate 32 and connected to the cover 20. It drives the cover 20 up and down as the actuating plate 32 pivots. Specifically, in this embodiment, the linkage rod 323 is located on the other side of the actuating plate 32 relative to the two push rods 322 and extends toward the first guide rail 11.
[0022] The linkage plates 33 are located on either side of the cover 20 and rotate with the actuating plate 32. In this embodiment, the linkage plates 33 are evenly spaced along the long side of the cover 20. Each linkage plate 33 has a first end 331 and a second end 332. The first end 331 is pivotally mounted on the base 31. The second end 332 is the other end of the linkage plate 33 opposite the first end 331 and is pivotally mounted on the cover 20. When the cover 20 moves upward until its top surface is flush with the top surface of the window frame 10, the first end 331 of each linkage plate 33 rotates closer to the top surface of the cover 20. This allows each linkage plate 33 to assist the linkage rod 323 in stabilizing the cover 20 in a position where its top surface is flush with the top surface of the window frame 10. At the same time, because the linkage plates 33 are distributed along the long side of the cover 20, even if the actuating plate 32 is disposed at one end of the cover 20, the linkage plates 33 can synchronously drive the other end of the cover 20 away from the actuating plate 32 to move up and down with the actuating plate 32.
[0023] The elastic member 34 is connected to the actuating plate 32 and causes the actuating plate 32 to rotate toward opposite sides. Specifically, in this embodiment, one end of the elastic member 34 is connected to the actuating plate 32, and the other end is connected to the base 31. Because the elastic member 34 tends to cause the actuating plate 32 to rotate toward the two side edges 321, it stabilizes the actuating plate 32 from shifting due to factors such as vibration and ensures that the actuating plate 32 does not become stuck at an arbitrary angle due to various factors. The seal 40 is located on the window frame 10 and, when the window sash A is closed, it seals tightly against the window sash A and the window frame 10.
[0024] When window sash A moves from the closed position to the open position within the window frame 10, it first moves from the first guide rail 11 to the second guide rail 12, and then moves along the second guide rail 12. At this point, the guide rod A1 of window sash A is located within the second guide rail 12 and pushes one of the push rods 322, rotating the actuating plate 32. This in turn drives the linkage rod 323 to rotate, allowing the cover 20 to move upward, bringing the top surface of the cover 20 flush with the top surface of the window frame 10. When window sash A moves from the open position to the closed position within the window frame 10, it moves along the second guide rail 12 and pushes the other push rod 322, causing the actuating plate 32 to rotate in the opposite direction, which in turn drives the linkage rod 323 to rotate in the opposite direction, allowing the cover 20 to descend below the top surface of the window frame 10. Then, window sash A moves from the second guide rail 12 back to the first guide rail 11, returning to the closed position.
[0025] The advantage of this invention lies in the design of a cover 20 that can be activated in conjunction with the opening and closing of the window sash A. Therefore, when the window sash A is opened, the cover 20 moves upward until its top surface is flush with the top surface of the window frame 10. This prevents users from tripping over uneven flat window frame tracks, or wheelchairs from getting stuck on the flat window frame tracks.
