Description

Technical Field

[0001] This application relates to the field of interior decoration technology, and in particular to a front upper crossbeam, a cabinet frame, and a cabinet. Background Technology

[0002] Kitchen cabinets are essential pieces of furniture in the kitchen, providing not only storage space but also enhancing the kitchen's tidiness and aesthetics. Through proper design, selection of suitable materials, and proper installation and maintenance, their functionality, durability, and beauty can be ensured.

[0003] Kitchen cabinets typically consist of a frame constructed from profiles, upon which composite panels are then installed. The top front beam is a crucial component of this frame, usually located at the top front of the cabinet. It connects the side panels and provides additional structural support. The top front beam not only enhances the cabinet's stability but also serves to install doors, decorative strips, and other elements, improving both the cabinet's aesthetics and functionality. Handle-less cabinet designs, by concealing or omitting traditional handles, create a cleaner, more streamlined look.

[0004] In existing handle-free cabinet frames, the handle-free profiles are fixed to the front upper crossbeam profiles by special plastic parts at both ends. This not only results in insufficient connection strength, but also means that the handle-free profiles cannot completely cover the cabinet panels when the countertop does not require underlayment (by adding composite board to thicken it), leading to exposed panels that affect the aesthetics.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] This application discloses a front upper crossbeam and a cabinet frame having the front upper crossbeam. The cabinet frame is the most basic and important part of the cabinet, responsible for supporting the weight of the entire cabinet and ensuring its stability and durability. The front upper crossbeam is the part used to form the cabinet frame.

[0040] The front upper crossbeam includes a crossbeam profile 10 and a handle-free profile 20. A first fastening part 11 is formed on one side of the crossbeam profile 10. Specifically, the first fastening part 11 is located on one of the two side walls opposite each other in the thickness direction of the crossbeam profile 10. The length direction of the first fastening part 11 is the same as the length direction of the crossbeam profile 10. A second fastening part 21 is formed on one side of the handle-free profile 20. The length direction of the second fastening part 21 is engaged with the first fastening part 11 and the second fastening part 21 in the length direction of the handle-free profile 20.

[0041] In this way, by forming a first snap-fit ​​part 11 on one side of the beam profile 10 and a second snap-fit ​​part 21 on one side of the handle-free profile 20, the handle-free profile 20 and the beam profile 10 are connected and fixed through the snap-fit ​​of the first snap-fit ​​part 11 and the second snap-fit ​​part 21. This directly eliminates the plastic parts in the prior art, resulting in higher structural strength, more convenient connection and fixation, and better reliability. Moreover, since the beam profile 10 and the handle-free profile 20 are relatively fixed by snap-fitting, different widths of handle-free profiles 20 can be installed to adapt to different thicknesses of countertops, depending on whether an under-hung structure is required. In cases where an under-hung structure is not required, handle-free profiles 20 of appropriate width can be installed according to the thickness of the board to completely cover the board, preventing the board from being exposed, improving aesthetics, and reducing costs.

[0042] For example, such as Figure 1 As shown, if it is a bottom-mounted design, then the width of the handle-free profile 20 assembled onto the crossbeam profile 10 is smaller; as Figure 2 and Figure 3 As shown, if no underhang is installed, the width of the handle-free profile 20 installed on the crossbeam profile 10 is relatively large, as long as it can cover the board.

[0043] The crossbeam profile 10 and the first fastening part 11 are integrally connected, for example, by using an open-mold integral molding method. The handle-free profile 20 and the second fastening part 21 are integrally connected to ensure the strength of the entire front upper crossbeam. The materials of the crossbeam profile 10 and the handle-free profile 20 are both aluminum alloy, which has the comprehensive excellent characteristics of low cost, high strength and light weight.

[0044] In this embodiment, there are at least two first fastening parts 11 and two fastening parts 21, and they are fastened in a one-to-one correspondence. That is, each first fastening part 11 is fastened to one second fastening part 21, so that the connection area between the beam profile 10 and the handle-free profile 20 is larger and the connection strength is higher.

[0045] Of course, in some embodiments, the number of the first fastening part 11 and the second fastening part 21 may be only one. For example, the length of the first fastening part 11 may be at least half the length of the crossbeam profile 10, and the length of the second fastening part 21 may be at least half the length of the handle-free profile 20. Both the first fastening part 11 and the second fastening part 21 may have a root-branched structure, thus enabling the first fastening part 11 and the second fastening part 21 to be fastened together. In addition, the crossbeam profile 10 and the first fastening part 11 may also be separate structures, connected by welding or other methods. Similarly, the handle-free profile 20 and the second fastening part 21 may also be separate structures, connected by welding or other methods.

[0046] Combination Figure 4 and Figure 5In this embodiment, a first groove 12 is formed between the first fastening part 11 and the crossbeam profile 10, and a portion of the second fastening part 21 is embedded in the first groove 12. A second groove 22 is formed between the second fastening part 21 and the handle-free profile 20, and a portion of the first fastening part 11 is embedded in the second groove 22. Thus, during cabinet assembly, the crossbeam profile 10 is fixed in a vertical position in the width direction and a horizontal position in the length direction, with the opening of the first groove 12 facing upwards. When the handle-free profile 20 is fastened to the crossbeam profile 10, the opening of the second groove 22 faces downwards. The first fastening part 11 is aligned with the second groove 22 in the width direction of the crossbeam profile 10, and the second fastening part 21 is aligned with the first groove 12 in the width direction of the crossbeam profile 10. Then, the handle-free profile 20 is pressed onto the crossbeam profile 10, causing a portion of the first fastening part 11 to embed into the second groove 22, and the second fastening part 21... A portion of the handle-free profile 20 can be embedded into the first groove 12 to achieve the snap-fit ​​connection between the handle-free profile 20 and the crossbeam profile 10; or, the first snap-fit ​​portion and the second snap-fit ​​portion can be aligned from the side of the crossbeam profile 10, so that a portion of the first snap-fit ​​portion is aligned with the second groove 22 in the length direction of the crossbeam profile 10, and a portion of the second snap-fit ​​portion is aligned with the first groove 12 in the length direction of the crossbeam profile 10. Then, the handle-free profile 20 is pressed onto the crossbeam profile 10 so that a portion of the first snap-fit ​​portion 11 is embedded into the second groove 22, and a portion of the second snap-fit ​​portion 21 is embedded into the first groove 12 to achieve the connection.

[0047] Specifically, the first fastening part 11 includes a first connecting part 13 and a first stop part 14 connected at an angle. The first connecting part 13 is connected to the crossbeam profile 10, and the first stop part 14 is directly opposite to the crossbeam profile 10. The first connecting part 13, the first stop part 14 and the crossbeam profile 10 together form a first groove 12. Correspondingly, the areas of the first stop part 14 and the areas of the crossbeam profile 10 that are directly opposite to the first stop part 14 form the two opposite inner sidewalls of the first groove 12. The first connecting part 13 forms the bottom of the first groove 12. The first stop part 14 is embedded in the second groove 22. In this way, the position of the first stop part 14 is restricted by the crossbeam profile 10, the first connecting part 13 and the first stop part 14.

[0048] The second fastening part 21 includes a second connecting part 23 and a second stop part 24 connected at an angle. The second connecting part 23 is connected to the handle-free profile 20, and the second stop part 24 is directly opposite to the handle-free profile 20. The second connecting part 23, the second stop part 24 and the handle-free profile 20 together form a second groove 22. The corresponding areas of the second stop part 24 and the area of ​​the handle-free profile 20 directly opposite to the second stop part 24 form the two opposite inner sidewalls of the second groove 22. The second connecting part 23 forms the bottom of the second groove 22. The first stop part 14 is embedded in the second groove 22, so that the second stop part 24 is restricted and held in position by the handle-free profile 20, the second connecting part 23 and the second stop part 24.

[0049] Optionally, the length of the first fastening portion 11 is greater than or equal to half the length of the crossbeam profile 10, and the first fastening portions 11 are spaced apart along the width direction of the crossbeam profile 10. Alternatively, the length of the first fastening portion 11 can be less than half the length of the crossbeam profile 10, and the first fastening portions 11 can be arranged in a matrix on the crossbeam profile 10. For example, it is feasible to divide the first fastening portions 11 into two columns along the width direction of the crossbeam profile 10, with at least two first fastening portions 11 in each column. This ensures sufficient connection area and guarantees reliable connection.

[0050] The length of the second fastening portion 21 is greater than or equal to half the length of the handle-free profile 20, and the second fastening portions 21 are arranged at intervals along the width direction of the handle-free profile 20. Alternatively, the length of the second fastening portion 21 can be less than half the length of the handle-free profile 20, and the second fastening portions 21 can be arranged in a matrix on the handle-free profile 20. For example, it is feasible to divide the second fastening portions 21 into two columns along the width direction of the handle-free profile 20, with at least two second fastening portions 21 in each column. This ensures sufficient connection area and guarantees reliable connection.

[0051] The crossbeam profile 10 has a first rib 15, a second rib 16, and a third rib 17 on one side of each of its two side walls in the width direction to improve the strength of the crossbeam profile 10. The first rib 15 is closer to the handle-free profile 20 than the second rib 16. The first rib 15, the second rib 16, and the third rib 17 are arranged at intervals along the thickness direction of the crossbeam profile 10. A first groove 18 is formed between the first rib 15 and the second rib 16, and a second groove 19 is formed between the second rib 16 and the third rib 17. The thickness of the first rib 15 is greater than that of the second rib 17. With a thickness of 16, the width of the first slot 18 is smaller than that of the second slot 19. In this way, when the beam profile 10 is made into a cabinet frame, the first rib 15 is located on the front outer side relative to the second rib 16 and the third rib 17. The decorative panel can be embedded in the first slot 18 and locked in by screws through the first rib 15. Compared with the prior art, where the rib is too thin to be screwed in and the decorative panel is only held in place by the slot, this can ensure the reliability of the connection and improve the strength of the cabinet. The second slot 19 can be used to hold tiles, etc.

[0052] In addition, this application also discloses a cabinet, which includes the cabinet frame described above, and therefore also includes the corresponding structure and beneficial effects, as detailed above, and will not be repeated here.

[0053] In summary, this application discloses a front upper crossbeam, a cabinet frame, and a cabinet. By forming a first fastening part 11 on one side of the crossbeam profile 10 and a second fastening part 21 on one side of the handle-free profile 20, the handle-free profile 20 and the crossbeam profile 10 are connected and fixed through the fastening of the first fastening part 11 and the second fastening part 21. This directly eliminates the plastic parts in the prior art, resulting in higher structural strength, convenient connection and fixation, and better reliability. Moreover, since the crossbeam profile 10 and the handle-free profile 20 are relatively fixed by fastening, different widths of handle-free profiles 20 can be installed to adapt to different thicknesses of the countertop, depending on whether the countertop needs to be under-hung. In cases where under-hung is not required, handle-free profiles 20 of appropriate width can be installed according to the thickness of the board to completely cover the board, preventing the board from being exposed, improving aesthetics, and reducing costs.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
