Description:FIELD OF THE INVENTION

The present disclosure relates generally to a door panel assembly, and particularly, the present invention relates to a bottom mounting panel for the door panel assembly.

BACKGROUND

Door panels are known for use in applications such as cupboards, entry/exit gates, furniture, etc. One of the types of door panels is sliding door panels, which have long been a staple in architectural and interior design, providing an elegant and space-saving solution for room dividers, closets, and various entryways. Conventional sliding door assemblies require door panels to be precisely fit into guide rails, a process that is inherently limited by the unchangeable width of these guide rails. Consequently, the door panels must conform to the standardized width of the guide rail to be accommodated correctly within the sliding door assemblies.

The conventional approach to installation of door panels in the sliding door assemblies poses several limitations. First and foremost, the conventional approach necessitates the production of door panels with specific widths matching those of the guide rails, which results in a lack of versatility. As a result, the door panels of different thicknesses cannot be seamlessly integrated into the guide rails without custom made design. Furthermore, such limitation has a direct impact on the design possibilities, due to limitation of the choice of materials and overall design flexibility. Addressing such limitations would not only expand design possibilities but also simplify installation processes of the door panels in the sliding door assemblies, thereby making the sliding doors a more adaptable option for residential and commercial applications.

Furthermore, the issue of gaps between door panels in conventional sliding door assemblies has been a persistent problem. The gaps allow the ingress of dust, pests, liquids, and other undesirable elements therein, and also into the enclosed spaces, compromising cleanliness. Therefore, the threats posed due to such gaps not only affect the overall functionality of the door, but also necessitate frequent maintenance and cleaning efforts.

The bottom mounting panel may be coupled to a bottom portion of the additional door panel.

The present disclosure is focused mainly on the construction and functioning of the bottom mounting panel 300 of the door panel assembly 100, as has also been depicted in Figures 2-4c. Specifically, Figure 2 illustrates a lower part of the door panel assembly 100 showing a detailed view of the bottom mounting panel 300 for the first door panel 200-1, and the second door panel 200-2 in the door panel assembly 100. In one embodiment, the bottom mounting panel 300 may include a bottom mounting panel 300 for the first door panel 200-1, and a bottom mounting panel 300 for the second door panel 200-2. Specifically, Figure 3A illustrates a perspective view of a bottom mounting panel 300A for a first door panel 200-1, and Figure 3B illustrates an exploded view of the bottom mounting panel 300A for the first door panel 200-1. Specifically, Figure 4A illustrates a perspective view of a bottom mounting panel 300B for a second door panel 200-2, Figure 4B illustrates a front view of the bottom mounting panel 300B for the second door panel 200-2, and Figure 4C illustrates an exploded view of the bottom mounting panel 300B for the second door panel 200-2.

Constructional aspects of the bottom mounting panel 300 shall now be explained in detail with reference to Figures 3a-4c, in conjunction with Figure 2. The bottom mounting panels 300A, 300B may include a mounting frame 302, a roller mount 324, and a height adjustment mechanism 320. The mounting frame 302 may be adapted to be coupled to the bottom portion 200-1B, 200-2B of the first door panel 200-1 and/or the second door panel 200-2. The mounting frame 302 may further include a base 302A with a first hole 328 and a pair of arms 302B extending downwards from the ends of the base 302A.

In one embodiment, the bottom mounting panel 300B for the second door panel 200-2 may be adapted to adjust a position of the second door panel 200-2 in the guide rail based on a thickness of the second door panel 200-2. In another embodiment, the bottom mounting panel 300A for the first door panel 200-1 may optionally be adapted to adjust a position of the first door panel 200-1 in the guide rail based on a thickness of the first door panel 200-1, as depicted in Figures 3a-3b.

Referring now to Figures 4a-4c, to adjust the door panel 200-1, 200-2 based on a thickness thereof, the bottom mounting panel 300A, 300B may include a bracket 308 with a first section 308A and a second section 308B. The first section 308A may be coupled to the base 302A of the mounting frame 302. A screw 334 may pass through a second hole in the base 302A to couple the second section 308B of the bracket 308 to the base 302A of the mounting frame 302. The screw 334 may be rotatable about an axis thereof, thereby allowing adjustment of the bracket's 308 position relative to the base 302A. The adjustment of the bracket’s 308 position may be based on the thickness of the second door panel 200-2. A locking unit 314 may be incorporated to secure the bracket 308 with the mounting frame 302 by locking the screw 334 upon completion of adjustment of the bracket 308. Once the bracket 308 is locked with the mounting frame 302, the base 302A of the mounting frame 302 may be covered with a cover 332 to prevent ingress of dust or any impurities in the bottom mounting panel 300B. In one embodiment, the mounting frame 302 may be covered with a back cover 336 to provide structural integrity to the mounting frame 302. During movement of the mounting frame 302, the back cover 336 moves along with the mounting frame 302, and the bracket 308 remains stationary.

In addition, the roller mount 324 may include a housing 310, a roller 312 rotatably installed in the housing 310, and a pair of springs 322 installed between the housing 310 and the mounting frame 302. The roller mount 324 may be slidably coupled to the mounting frame 302 and may be adapted to slide between the pair of arms 302B, which allows the roller mount 324 to be securely mounted in the bottom guide rail 106 of the door panel assembly 100.

Now referring to Figures 3a-4c, the bottom mounting panels 300A, 300B may be adapted to adjust an overall height of the door panels 200-1, 200-2. To aid the same, the height adjustment mechanism 320 may be disposed on the mounting frame 302 and may be adapted to slide the roller mount 324 relative to the mounting frame 302. The height adjustment mechanism 320 may include a screw 304 having a body 304-1 disposed in the first hole 328 and a tip 304-2 adapted to push the roller mount 324 to slide the roller mount 324 between the pair of arms 302B, thereby facilitating adjustment of an overall height of the bottom mounting panels 300A, 300B.

The reduced need for extensive modifications during installation and the improved maintenance efficiency contribute to cost savings for both residential and commercial applications. Additionally, the adaptability of the door panel assembly 100 due to the bottom mounting panel 300A, 300B minimizes the likelihood of expensive customization requirements. Further, the bottom mounting panel 300A, 300B not only addresses existing limitations but also enhances the overall functionality of the door panel assembly 100. The adaptability of the door panel assembly 100 due to the bottom mounting panel 300A, 300B can lead to the use of more sustainable materials and designs, contributing to a reduced environmental footprint in construction and interior design projects.

Additionally, the mounting assembly 600 may further include a locking unit 318 positioned on a portion of one of the pair of arms 302B. In one example, the locking unit 318 may include, but is not limited to, a nut. The locking unit may be adapted to lock the roller mount 324 securely with the pair of arms 302B once the roller mount 324 is slidably mounted in the bottom guide rail 106 of the door panel assembly 100. Additionally, a locking unit 314 may be provided for locking the bracket 308 with the mounting frame 302 after the adjustment process.

In one embodiment, the bottom mounting panel 300B may include a pair of measurement bars 316 extending orthogonally from a surface of the bracket 308 towards the mounting frame 302. Each of the pair of measurement bars 316 may include a plurality of graduations 316A adapted to indicate a linear displacement of the bracket 308 along the axis while the bottom mounting panel 300B is being adjusted into the bottom guide rail 106 based on a thickness of the door panel 200-2.

In addition, the bottom mounting panel 300B may include cleaning structures 306 to clean the guide rail 106 of the door panel assembly 100. In one example, the cleaning structures 306 may include, but are not limited to, brushes. During the sliding of the door panels 200-1, 200-2 in the guide rails 106, the cleaning structures may be adapted to broom away the impurities out of the guide rails 106. Such cleaning of the guide rails 106 may help in the longevity of the door panel assembly 100, and also seamless functioning thereof.

In one embodiment, even after accommodating the door panels 200-1, 200-2 based on the thickness thereof, there may still be a need to seal any gaps between the door panels 200-1, 200-2 for cleanliness purposes. To seal the same, the door panel assembly 100 may include a dust strip 326 disposed between the first door panel 200-1, the second door panel 200-2, and/or the additional door panels, as depicted in Figure 5. Specifically, Figure 5 illustrates a dust strip 326 disposed between the first door panel 200-1 and the second door panel 200-2. The dust strip 326 may be adapted to prevent the ingress of impurities and pests between adjacent door panels. By effectively sealing the gaps between the door panels 200-1, 200-2, the door panel assembly 100 eliminates the entry points for dust, pests, liquids, and other unwanted elements. Such an enhancement not only improves cleanliness, but also enhances the overall functionality and longevity of the door panel assembly 100.

The bottom mounting panel 300A, 300B of the present disclosure allows for the accommodation of the door panels 200-1, 200-2 with varying thicknesses. The bottom mounting panel 300 therefore helps in opening up possibilities for enabling architects and interior designers to select from a broader range of door panels and create custom solutions to suit diverse requirements with respect to the guide rails 104, 106. Unlike conventional systems, the bottom mounting panel 300A, 300B disclosed herein simplifies the process of retrofitting sliding doors into any existing furniture or openings. The ability to adapt to different thicknesses of door panels 200-1, 200-2 reduces the need for costly structural modifications thereof.

In addition, reduced gaps between the door panels 200-1, 200-2 help in easier maintenance and cleaning of the door panel assembly 100. With fewer areas for dirt and debris to accumulate, the door panel assembly 100 is more user-friendly and requires less frequent upkeep, saving both time and resources.

While specific language has been used to describe the present disclosure, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments.
