Description

Technical Field

[0001] This utility model relates to windows, and more particularly to a window structure for factory buildings. Background Technology

[0002] The floor height of a factory building is designed according to the specific usage environment. For factories involving the machining of large workpieces, overhead cranes are required. Light-duty overhead crane factories typically have a floor height of six to nine meters, medium-duty overhead crane factories typically have a floor height of nine to twelve meters, and heavy-duty overhead crane factories typically have a floor height of twelve to fifteen meters. To facilitate the entry and exit of trucks for loading and unloading workpieces, factory doors are also designed to be relatively high. Considering these factors, windows are generally designed at higher locations in the factory building to ensure ventilation. Correspondingly, opening and closing windows at higher locations is more inconvenient. Utility Model Content

[0016] Please see Figure 1 and Figure 2 A window structure for a factory building includes: a window unit 1 and a drive unit 2.

[0017] Window unit 1 includes: window frame 11, a pair of sliders 12, a pair of first rods 13, a pair of second rods 14, a pair of third rods 15, a pair of fourth rods 16, and window panel 17. That is, sliders 12, first rods 13, second rods 14, third rods 15, and fourth rods 16 are divided into two groups and symmetrically arranged on the left and right sides of window frame 11.

[0018] The slider 12 is slidably connected to the upper side of the window frame 11. More specifically, the window frame 11 has a groove 11A for the slider 12 to slide.

[0019] The lower end of the first rod 13 is hinged to the lower side of the window frame 11, meaning the hinge position of the first rod 13 on the window frame 11 is lower than that of the slider 12. The upper end of the second rod 14 is hinged to the lower side of the slider 12, and the lower end is hinged to the middle of the first rod 13. Accordingly, the slider 12, the first rod 13, and the second rod 14 form a crank-slider 12, meaning that as the slider 12 moves up and down, the first rod 13 swings accordingly.

[0020] The third rod 15 is hinged at the middle position to the second end of the first rod 13. One end of the fourth rod 16 is hinged to the upper side of the slider 12, and the other end is hinged to the upper end of the third rod 15. The slider 12, the first rod 13, the second rod 14, the third rod 15, and the fourth rod 16 form a five-bar linkage.

[0021] For a five-bar linkage, two links need to have inputs to determine the motion. Accordingly, as slider 12 moves up and down, the first link 13 swings along with it, that is, slider 12 and the first link 13 are used as the two inputs of the five-bar linkage.

[0022] Please see Figure 2 and Figure 3 The third rod 15 has a vertical state and an inclined state during the swinging process. The window panel 17 is fixedly connected to the third rod 15. When the third rod 15 is in the vertical state, the window panel 17 is in the closed state; when the third rod 15 is in the inclined state, the window panel 17 is in the open state.

[0023] Please see Figure 4 A connecting rod 16A can also be fixed between the two fourth links. The specific connection position of the connecting rod 16A can be the hinge position between the fourth link and the slider 12. This improves the synchronization of movement and will not significantly obstruct the glass 17A of the window panel 17, thus affecting the aesthetics.

[0024] Please see Figure 5 and Figure 6 In some embodiments, the cross-section of the third rod 15 is T-shaped. More specifically, the hinge positions of the first rod 13 and the third rod 15, and the hinge positions of the fourth rod 16 and the third rod 15 are both in the vertical portion, while the window panel 17 is fixed in the horizontal portion at the position of the third rod 15.

[0025] Correspondingly, during the swinging process of the third rod 15, when the horizontal part is lifted to the fourth rod 16, the third rod 15 reaches its maximum tilt angle, that is, the window panel 17 reaches its maximum opening degree. For window closure, the third rod 15 is in a vertical state when the slider 12 is pressed against the inner top wall of the window frame 11.

[0026] Please see Figure 1 and Figure 7 The drive unit 2 is located between the window frame 11 and the slider 12, and is used to drive the slider 12 to move. That is, the drive unit 2 is a linear drive mechanism.

[0027] In some embodiments, the drive unit 2 may be a lead screw module, which may be either motor-driven or hand-cranked.

[0028] Please see Figure 4 In some embodiments, the drive unit 2 includes a rack 21, a gear 22, an input shaft 23, and a drive element 24.

[0029] The rack 21 is fixedly connected to the window frame 11. The gear 22 is rotatably connected to the slider 12, and the gear 22 also meshes with the rack 21 to form a gear 22 and rack 21 pair.

[0030] The input shaft 23 is rotatably connected to the slider 12. A worm gear 23A is also provided between the input shaft 23 and the gear 22, that is, the worm gear 23A is connected to the input shaft 23, and the worm wheel 22A is connected to the gear 22, which reduces speed from the input shaft 23 to the gear 22. More specifically, the input shaft 23, the worm wheel 22A, and the worm gear 23A can be connected to the same mounting bracket 12A. The mounting bracket 12A is detachably connected to the slider 12. While the mounting bracket 12A is connected to the slider 12, the worm wheel 22A and the gear 22 rotate together through a plug-in connection.

[0031] The drive unit 24 is connected to the input shaft 23. The input shaft 23 can be driven to rotate by a motor or manually by a hand crank.

[0032] The input shaft 23 rotates to drive the gear 22 to rotate, thereby causing the slider 12 to move up and down. The self-locking of the worm gear 22A and worm 23A ensures that the slider 12 can remain in the corresponding position after it stops moving.

[0033] Based on the selection of a hand crank as the driving component 24, in some embodiments, a universal joint coupling 23B is provided between the hand crank and the input shaft 23.

[0034] The hand crank can be tilted at a certain angle relative to the input shaft 23, making it easier to rotate manually.

[0035] Please see Figure 6 In some embodiments, based on the drive unit 2 including rack 21, gear 22, input shaft 23 and drive member 24, the slider 12 includes a sliding part 121 and a mounting part 122.

[0036] The sliding portion 121 is convex and is used for sliding connection with the window frame 11. The window frame 11 has an L-shaped protrusion 11B. The fixed connection between the rack 21 and the window frame 11 is detachable; more specifically, the rack 21 and the window frame 11 can be fixedly connected using a first screw. In the connected state, a groove 11A is formed between the rack 21 and the window frame 11 to engage the sliding portion 121. Correspondingly, the teeth of the rack 21 are located on the side away from the window panel 17.

[0037] The mounting portion 122 is detachably connected to the sliding portion 121. More specifically, the mounting portion and the sliding portion can be fixedly connected by a second screw. The mounting portion 122 is used for the rotatable connection of the gear 22. Correspondingly, the aforementioned mounting bracket 12A is the mounting portion at the connection position of the slider 12.

[0038] More specifically, the mounting portion 122 has an oblong groove through which the second screw passes, so that when the mounting portion 122 and the sliding portion 121 are fixedly connected, the fixed position can be adjusted back and forth to ensure the meshing of the gear 22 and the rack 21.

[0039] In addition, the mounting part is relatively long in the front-to-back direction. In order to improve the stability of the mounting part, the rack 21 has a trapezoidal groove 21A, the first screw is designed to be countersunk, and a trapezoidal block 21B is slidably connected in the trapezoidal groove 21A. While the mounting part 122 is fixedly connected to the sliding part 121, the mounting part 122 and the trapezoidal block 21B are fixedly connected by a third screw.

[0040] The slider 12 is designed as a sliding part 121 and a mounting part 122, which makes the sliding connection assembly between the slider 12 and the window frame 11 more convenient, and also makes the meshing assembly between the rack 21 and the gear 22 more convenient.

[0041] Please see Figure 6 and Figure 8 In some embodiments, the drive unit 2 includes a rack 21, a gear 22, an input shaft 23, and a drive member 24. Both ends of the shaft of the gear 22 extend out from the mounting portion 122 to form a connecting section 22B.

[0042] One connecting section 22B is used to insert into the worm gear 22A, and another connecting section 22B is used to connect multiple window structures with connecting shafts, so that multiple window panels 17 can be opened / closed simultaneously.
