Description

Technical Field

[0001] This utility model belongs to the field of furniture manufacturing technology, specifically relating to a slotless through-door handle assembly. Background Technology

[0002] Cabinet door handles are not only functional components that enable cabinet doors to open and close, but also key decorative elements that determine the overall aesthetic effect of the product. Currently, the mainstream installation methods for cabinet door handles are mainly divided into two categories: surface-mounted and recessed.

[0003] Surface-mounted handles are directly fixed to the front of the door panel with screws. Although the installation is simple, the screw holes are exposed on the door panel surface, which disrupts the integrity of the door panel and makes the visual effect less concise, making it difficult to meet the pursuit of aesthetic integration in high-end customization.

[0004] To achieve a simpler, more seamless look, recessed handles (such as G-type, C-type, and recessed handles) have emerged. These handles typically require grooving on the side or front of the door panel to embed the handle base or body into the groove, achieving a flush installation with the door panel. However, this grooving process has significant limitations, especially when dealing with high-end door panels with finishes such as painted, laminated, or wood veneer finishes.

[0005] 1. Destructive processing and quality risks: The grooving process will cause irreversible cutting to the door panel substrate, which may not only damage the internal structural stress and increase the risk of door panel deformation, but also easily cause quality problems such as paint cracking, surface curling or poor edge sealing at the groove edge, which seriously affects product yield and durability.

[0006] 2. Complex process and high cost: The requirements for the precision and smoothness of the grooving are extremely high, requiring special CNC equipment for processing, which increases the complexity and time cost of the production process, and also drives up the manufacturing cost.

[0007] Therefore, the market urgently needs an innovative handle installation solution that can achieve the simple and modern aesthetic effect of embedded handles, while completely avoiding any grooving treatment on high-end door panels, thus fundamentally overcoming the shortcomings of existing technologies. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a slotless through-door handle assembly, which solves the drawbacks of slotted door panels and the problem of door panel aesthetics when installing handles in the above-mentioned background art.

[0009] The technical solution adopted by this utility model to solve its technical problem is as follows: a slotless through-door handle assembly is provided, which is installed on the edge of a door panel and includes a through-door handle, at least two bases, fasteners, and end caps; the through-door handle has a handle part, a baffle, and a sliding groove; the bases are fixed to the end face of the door panel at intervals by fasteners, and the bases have bosses, which are parallel to the end face of the door panel and have a gap between them to form a slide rail, and the sliding groove is inserted into the slide rail along the length of the door panel; the end caps have positioning pins, and the ends of the through-door handle and the bases have positioning holes, and the positioning pins are inserted into the positioning holes.

[0010] In a preferred embodiment of the present invention, the handle, the baffle, and the slide groove are connected in sequence to form a C-shaped handle groove, and the opening of the slide groove faces away from the handle.

[0011] In a preferred embodiment of the present invention, the sidewall of the slide groove is recessed inward to form a flange, and the flange is inserted into the gap between the boss and the end face of the door panel.

[0012] In a preferred embodiment of the present invention, the door handle is further provided with an edge banding strip, which is disposed on the side wall of the slide groove and covers the joint between the slide groove and the end of the door panel.

[0013] In a preferred embodiment of the present invention, the fastener includes a screw, the fastener is perpendicular to the base, and the fastener enters from the end face of the door panel and is parallel to the plane of the door panel.

[0014] In a preferred embodiment of the present invention, the upper surface of the base is recessed to form a clearance portion.

[0015] In a preferred embodiment of this utility model, the positioning holes are located on the inner side of the handle and on the bases installed at both ends of the door panel, and the positioning pins are located at the four corners of the end cap.

[0016] In a preferred embodiment of this utility model, the length of the door handle and the thickness of the end caps at both ends are equal to the length of the door panel.

[0017] In a preferred embodiment of this utility model, the bottom of the end cap is provided with a constriction opening.

[0018] In a preferred embodiment of this utility model, the fastener is locked to the core layer of the painted door panel.

[0019] Compared with the prior art, this technical solution has the following advantages:

[0020] 1. This solution completely avoids any grooving or cutting work on the front or side of the door panel, fundamentally eliminating the risk of paint layer cracking, film peeling or solid wood veneer damage caused by mechanical processing. In addition, there are no gaps, exposed screws or seams on the front and side of the door panel, avoiding the safety hazards of aluminum edge scratches. It achieves a truly "seamless" design, maximizes the protection of the door panel's integrity, preserves the overall structural strength and surface aesthetics of the door panel itself, and prevents the door panel from deforming later. It is especially suitable for expensive or fragile high-end door panels such as painted, veneered, and fireproof boards.

[0021] 2. This solution simplifies the production process, shortens the processing time, and effectively reduces the scrap rate and production costs caused by processing errors, resulting in significant economic benefits.

[0022] 3. This solution is easy to install and has a high fault tolerance rate. In subsequent use, if replacement or repair is required, it will be more convenient and quick, without having to replace the entire door panel.

[0023] 4. The number of bases in this solution can be adjusted according to the door panel. The structure is stable and reliable, and the handle assembly forms a universal structure with strong adaptability. Attached Figure Description

The handle assembly includes a through-door handle 1, three bases 4, fasteners 2, and end caps 3. The bases 4 can be made of plastic and serve as a medium connecting the aluminum handle profile to the wooden door panel 5. At least two bases 4 are located at both ends of the door panel 5 (2mm from the edge, reserving space for the end caps 3 installation), with the remaining bases 4 spaced apart. The number and position are adjusted according to the length of the door panel 5.

[0036] The door handle 1 is provided with a handle part 11, a baffle 12, a slide groove 13, and an edge strip 14. The handle part 11, the baffle 12, and the slide groove 13 are connected in sequence to form a handle groove with a C-shaped cross section. The opening of the slide groove 13 faces downward, and the two side walls of the slide groove 13 are recessed inward to form a flange.

[0037] The base 4 is fixed to the end face of the door panel 5 at intervals by fasteners 2. The base 4 is provided with a boss 41. The boss 41 is parallel to the end face of the door panel 5 and leaves a gap between it and the end face of the door panel 5 to form a slide rail. The slide groove 13 is inserted into the slide rail along the length direction of the door panel 5. At this time, the flange is inserted into the gap between the boss 41 and the end face of the door panel 5.

[0038] In this embodiment, the fastener 2 is a screw. The fastener 2 is perpendicular to the base 4 and enters from the end face of the door panel 5, parallel to the plane of the door panel 5. With this fixing method, when using a painted panel, the fastener 2 can be locked to the core layer of the painted door panel 5, preventing the painted layer from cracking or breaking, and protecting the appearance of the door panel 5 to the greatest extent.

[0039] The upper surface of the base 4 is recessed to form a relief portion 43, and the screw head is embedded in the relief portion 43 to ensure that the screw is flush with the aluminum material and does not protrude after being tightened, thus avoiding obstruction of the insertion and achieving a hidden connection.

[0040] The end cap 3 is provided with a positioning pin 31, and the ends of the door handle 1 and the base 4 are provided with positioning holes 42, and the positioning pin 31 is inserted into the positioning hole 42. In this embodiment, the end cap 3 is rectangular, the positioning hole 42 is provided on the inner side of the handle part 11 and on the base 4 installed at both ends of the door panel 5, and the positioning pin 31 is located at the four corners of the end cap 3 respectively.

[0041] In this embodiment, the through-door handle 1 is cut according to the dimensions of the door panel 5. The cutting dimension is L - 4mm, which means that the length of the through-door handle 1 and the thickness of the end caps 3 at both ends are equal to the length of the door panel 5. The through-door handle 1 is also provided with an edge banding strip 14. The edge banding strip 14 is set on the side wall of the slide groove 13 and covers the joint between the slide groove 13 and the end of the door panel 5, covering the joint between the aluminum profile and the wooden door panel 5. In addition, the bottom of the end cap 3 is provided with a tapered end 32, realizing a truly "seamless" design.
