Description

Technical Field

[0001] The present invention generally relates to door and window systems, and more specifically, to a fixing device for a multi-door or window system, and the multi-door or window system. Background Technology

[0002] Multi-leaf door and window systems typically include one or more sliding sashes. When these sashes slide against each other, wobbling and noise may occur; furthermore, in the fully extended state, adjacent sashes may wobble or even become displaced. These defects become more pronounced as the sash size increases. Therefore, it is desirable to provide a fixing device suitable for multi-leaf door or window systems to effectively reduce wobbling and improve the overall stability of the door or window system. Summary of the Invention

[0003] Accordingly, a first aspect of the present invention provides a fixing device for a multi-door or window system. The fixing device includes a base plate, a first arm, and a second arm, both of which are attached to the base plate; wherein the first arm and the second arm are parallel to each other and are arranged in a staggered manner.

[0004] A second aspect of the invention provides a multi-pane door or window system comprising a plurality of slidably oriented slats and at least one fixing device as described in the first aspect of the invention. Each slat has a groove at at least one sliding edge; a first arm and a second arm of the at least one fixing device are slidably fitted into the respective grooves of the first and second slats, wherein the first and second slats are arranged adjacent to each other.

[0005] Other aspects and advantages of the invention will be set forth in conjunction with the accompanying drawings and the following detailed description, which illustrates the principles of the invention by way of example only. Attached Figure Description

Detailed Implementation

[0007] The following detailed description, taken in conjunction with the accompanying drawings, is intended to describe the currently preferred embodiments of the present invention and is not intended to limit the invention to the forms described. It should be understood that those skilled in the art can achieve the same or equivalent functions using different embodiments without departing from the spirit of the invention, and such alternative embodiments should all fall within the protection scope of the present invention.

[0008] See now Figure 1A The figure shows a fixing device 10 for a multi-panel door or window system (not shown). The fixing device 10 includes a base plate 11, a first arm 12 attached to the base plate 11, and a second arm 14 attached to the base plate 11. The first arm 12 and the second arm 14 are parallel to each other and staggered. The fixing device 10 can fix or lock adjacent panels of the multi-panel door or window system in a sliding or stationary state. Advantageously, this helps reduce swaying and improves the stability and structural strength of the entire multi-panel door or window system.

[0009] The substrate 11 can be a Z-shaped plate, with the first arm 12 and the second arm 14 respectively attached to their respective arms. Thus, the first arm 12 and the second arm 14 can form a zigzag or Z-shaped connection structure via the Z-shaped substrate, preventing them from being on the same straight line. Advantageously, this zigzag or Z-shaped arrangement enhances the overall rigidity of the fixing device 10 and effectively prevents deformation or failure of the fixing device 10 under shear stress.

[0010] In the illustrated embodiment, the fixing device 10 includes a plurality of roller assemblies 16. At least one roller assembly 16 may be attached to a first arm 12, and at least one roller assembly 16 may be attached to a second arm 14. The roller assemblies 16 facilitate smooth movement of the fixing device 10 relative to the sliding slats of the multi-door or window system, thereby improving the operational convenience of the multi-door or window system employing the fixing device 10.

[0011] To enhance stability, a first roller assembly 16a can be installed at the distal or leading end of the first arm 12, and a second roller assembly 16b can be installed at the distal or leading end of the second arm 14. To further improve stability, a third roller assembly 16c can be installed at the proximal or trailing end of the first arm 12, and a fourth roller assembly 16d can be installed at the proximal or trailing end of the second arm 14. Although this embodiment shows four roller assemblies 16, those skilled in the art will understand that the number and specific arrangement of the roller assemblies 16 do not constitute a limitation of the invention; in other alternative embodiments, fewer or more roller assemblies can be installed.

[0012] In the illustrated embodiment, the rollers or wheels 18 in each roller assembly 16 are rotatable in the plane containing the first arm 12 and the second arm 14. In one or more alternative embodiments, the rollers or wheels 18 in the roller assembly 16 are rotatable in a plane parallel to the plane in which the first arm 12 and the second arm 14 extend or lie. The advantage of this arrangement of rollers or wheels 18 is that the fixing device 10 can independently engage with each sliding slat of the multi-door or window system without interfering with or obstructing the sliding mechanism of the multi-door or window system.

[0013] See now Figure 1B The roller assembly 16 may include a first roller 18a, a second roller 18b, and a connector 20; the connector 20 connects a first shaft 22a of the first roller 18a to a second shaft 22b of the second roller 18b. The connector 20 is rotatably mounted on one of the first arm 12 and the second arm 14. Advantageously, this configuration allows the unfolded width of the roller assembly 16 to be adjusted relative to the width of the first arm 12 or the second arm 14 to which the connector 20 is attached. For example, depending on the orientation of the connector 20 relative to the first arm 12 or the second arm 14 to which the connector 20 is attached, the unfolded width of the roller assembly 16 may be limited within the width of that first arm 12 or the second arm 14, or extended beyond that width.

[0014] In this embodiment, the connector 20 is rotatably mounted on one of the first arm 12 and the second arm 14 via a rotating mechanism 24. The rotating mechanism 24 includes a plate 26 with a bent portion 28, which is slidably mounted on one of the first arm 12 and the second arm 14. In the illustrated embodiment, the bent portion 28 has a through hole 30, and the plate 26 has an arc-shaped groove 32. In this embodiment, the rotating mechanism 24 also includes a rotating shaft 34 that passes through the connector 20 and the arc-shaped groove 32 on the plate 26, thereby attaching the connector 20 to one of the first arm 12 and the second arm 14. In the illustrated embodiment, the rotating mechanism 24 also includes a screw 36 that passes through the through hole 30 in the bent portion 28. The screw 36 is operable to drive the plate 26 to move along the length of one of the first arm 12 and the second arm 14, simultaneously rotating the connector 20. In use, the rotation of screw 36 causes plate 26 to move or slide along one of the first arm 12 and the second arm 14. As plate 26 moves, the arcuate groove 32 on plate 26 slides along the pivot 34 and applies force to it, forcing the pivot 34 to rotate, which in turn drives the connector 20 attached to the pivot 34 to rotate. Advantageously, a screwdriver can be used to adjust the side adjustment of the spread of the roller arrangement 16, thereby facilitating the installation and removal of the fixing device 10 in a multi-door or window system.

[0015] See you again Figure 1A One or more spring-loaded rollers 38 may also be attached to the first arm 12, and these spring-loaded rollers 38 are biased in a direction perpendicular to the base plate 11. Advantageously, when the fixing device 10 is installed at the bottom edge of the multi-door or window system, the one or more spring-loaded rollers 38 can effectively improve the smoothness and stability of the sliding process. To facilitate operation or use of the fixing device 10 in these embodiments, a first spring-loaded roller 38a may be attached to the front end or distal end of the first arm 12. To further enhance the stability of the sashes during the sliding process of the multi-door or window system, a second spring-loaded roller 38b may also be attached to the rear end or proximal end of the first arm 12 (see...). Figure 2D ).

[0016] See now Figures 2A to 2D The diagram illustrates a multi-door or window system 50. This system includes a plurality of slidably arranged sashes 52 and at least one of the aforementioned fixing devices 10. Each sash 52 has a groove or guide groove 54 at at least one sliding edge. The first arm 12 and the second arm 14 of the at least one fixing device 10 are slidably embedded in the respective grooves or guide grooves 54 of the first sash 52a and the second sash 52b, respectively, with the first sash 52a and the second sash 52b adjacent to each other.

[0017] Figure 2A , 2B Figures 2C and 2C respectively show the multi-door or window system 50 using the fixing device 10 in a closed state, a partially opened state, and a fully opened state. To achieve full closure, the length of one of the first arm 12 or the second arm 14 may be equal to or less than half the width of its corresponding first leaf 52a or second leaf 52b.

[0018] Advantageously, the fixing device 10 helps to fix or lock adjacent first slats 52a and second slats 52b during sliding or in a stationary state, thereby reducing swaying and improving the stability and structural rigidity of the multi-door or window system 50.

[0019] Furthermore, the fixing device 10 can be easily installed into or removed from the multi-door or window system 50: by rotating the connector 20, the unfolded width of the roller assembly 16 can be made smaller than the opening width of the slide groove, thereby smoothly inserting or withdrawing the roller assembly 16 into or out of the slide groove or guide groove 54 of the corresponding leaf blade 52. This operation can be easily completed by turning the screw 36 in the rotating mechanism 24 with a screwdriver. Since the screw hole 30 is located on the bend 28 of the plate 26, the screw 36 can be easily accessed from the side of the multi-door or window system 50.

[0020] Similarly, once the fixing device 10 has been inserted into the groove or guide groove 54 of the sash 52, the first roller 18a and the second roller 18b in the roller assembly 16 can be rotated to press against the inner wall of the groove or guide groove 54 of the sash, thereby easily achieving fixation. Likewise, since the screw hole 30 is located on the bent portion 28 of the plate 26, this can be easily achieved by using a screwdriver to tighten the screw 36 of the rotating mechanism 24 from the side of the multi-door or window system 50.

[0021] In practical use, when one or more slats 52 of the multi-door or window system 50 slide relative to each other between the closed and open states, the rollers or rollers 18 in the roller assembly 16 will roll within the grooves or guides 54 of the slats 52. The advantages of this roller arrangement are: on the one hand, it ensures that the fixing device 10 is reliably anchored to the multi-door or window system 50; on the other hand, it allows the fixing device 10 to independently cooperate with each slat 52 of the multi-door or window system 50 without interfering with or hindering the sliding mechanism of the multi-door or window system 50.

[0022] In the illustrated embodiment, the fixing device 10 is attached to the lower edge of the sliding fan blade 52. Figures 2A to 2CThe diagram shows a schematic bottom perspective view of a multi-leaf door or window system 50. Although only one fixing device 10 is shown in this embodiment, those skilled in the art will understand that the invention does not limit the number or installation position of the fixing devices 10. In other alternative embodiments, multiple fixing devices 10 may be provided, for example, simultaneously located at the upper and lower edges of the sliding leaf 52. Similarly, although this embodiment shows a double-leaf door / window system, those skilled in the art will understand that the invention is not limited to double-leaf door / window systems. For example, one or more of the aforementioned fixing devices 10 may be provided in a door or window system with three or more leaf blades.

[0023] During use, such as Figure 2B As shown, the first panel 52a can slide away from the second panel 52b, thereby moving the multi-pane door or window system 50 to... Figure 2C The fully extended state is shown. To prevent the second arm 14 of the fixing device 10 from dislodging from the slide groove 54 when the first fan blade 52a slides away from the second fan blade 52b, a first stop 56a can be provided at the distal end of the slide groove 54 of the second fan blade 52b. At the same time, to prevent the first fan blade 52a from slipping off the first arm 12 of the fixing device 10 when it slides away from the second fan blade 52b, a second stop 56b can be provided at the proximal end of the slide groove 54 of the first fan blade 52a.

[0024] To restore the multi-door or window system 50 to Figure 2A In the retracted state shown, the first fan blade 52a can be slid towards the second fan blade 52b. To prevent the first fan blade 52a from slipping off the first arm 12 of the fixing device 10 when it slides towards the second fan blade 52b, a third stop 56c can be added to the far end of the groove 54 of the first fan blade 52a.

[0025] See now Figure 2D The diagram shows a partial cross-sectional view of a multi-door or window system 50 employing a fixing device 10. In the illustrated embodiment, a slope 58 is provided within the groove of the second sash 52b. This slope 58 ensures that one or more spring-loaded rollers 38 automatically lift off the ground when the first sash 52a retracts towards the second sash 52b. This facilitates smooth sliding of the first sash 52a of the multi-door or window system 50 between its retracted and extended states. To optimize the sliding of the first sash 52a of the multi-door or window system 50, the first spring-loaded roller 38a may be located at the free end or front end of the first arm 12 of the fixing device 10; to enhance the stability of the first sash 52a during sliding, the second spring-loaded roller 38b may be located at the rear end or proximal end of the first arm 12 of the fixing device 10.

[0026] See now Figure 2EThis is a partially enlarged perspective view of the first leaf 52a and the second leaf 52b in a multi-leaf door or window system 50. In the illustrated embodiment, a first hook 60 is provided near the distal edge 62 of the slide groove 54 of the second leaf 52b, and a second hook 64 is provided near the proximal edge 66 of the slide groove 54 of the first leaf 52a. When the multi-leaf door or window system 50 is in the fully extended state, the first hook 60 is operable to engage with the second hook 64. Advantageously, the engagement of the first hook 60 and the second hook 64 helps to prevent the first leaf 52a and the second leaf 52b of the multi-leaf door or window system 50 from accidentally separating in the fully extended state when the first leaf 52 slides to the fully extended state, thereby improving system safety and reliability.

[0027] As can be seen from the above discussion, the fixing device for a multi-door or window system provided by the present invention can fix or lock adjacent door slats in a sliding or stationary state. Advantageously, this helps to reduce swaying and improve the stability and structural strength of the multi-door or window system. Further advantageously, the fixing device of the present invention can be easily installed into a multi-door or window system.
