Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a concealed panel structure for furniture. Background Technology

[0002] With the integration of furniture design, how to achieve integration and concealment of products such as smart furniture cabinets has always been a key design challenge. For example, the structure of the panel or cabinet has always been a design difficulty.

[0003] Existing panels generally use a sliding structure or a flip structure. The sliding structure requires a guide rail, so it occupies a large amount of external space to accommodate the panel when it is opened.

[0004] Commonly used flip-up panels often have exposed hinges or require the panel to extend outside the cabinet, thus opening the furniture's storage cavity and affecting the user experience. Utility Model Content

[0005] The main purpose of this invention is to propose a concealed panel structure for furniture, which aims to improve existing furniture panels by concealing their hinges and integrating the panel design. When the receiving cavity is opened, the panel can extend into the receiving cavity, thereby reducing the occupation of external space and improving the aesthetics of the furniture.

[0006] To achieve the above objectives, this utility model proposes a concealed panel structure for furniture, comprising:

[0007] The handrail is a cavity with an opening at the top, and the rear wall of the cavity is arc-shaped and forms a guide cavity;

[0008] The panel has cranks extending in an arc shape from both sides of its rear end. Each crank includes an arc-shaped portion and a horizontal portion.

[0009] The horizontal part is horizontal with the panel.

[0010] The horizontal section is provided with a pivot section at its end, and the pivot section is rotatably mounted on both sides of the armrest seat;

[0011] The rear end of the panel is fitted into the guide cavity;

[0012] A locking device is provided on both sides of the armrest seat, and the locking device is used to lock the panel when it covers the opening;

[0013] When the locking device is unlocked, the panel can be inserted into the cavity and its upper part can be extended out under the drive of the elastic element.

[0014] In actual design, the combination of the hand armrest with an open mouth and the panel can make the panel hide when it is open, and the hand armrest and the panel are integrated when the opening is closed, which improves the aesthetic design of the furniture.

[0015] In the actual design, the armrest is designed with a guide cavity that abuts against the rear of the panel, thereby improving the rotational stability and guiding stability of the panel and enhancing the user experience. Attached Figure Description

[0033] like Figures 1 to 6 As shown, a concealed panel structure for furniture includes:

[0034] The handrail 1 is a cavity 12 with an opening 11 at the upper end. The rear wall of the cavity 12 is arc-shaped and forms a guide cavity 4.

[0035] Panel 2, with cranks 20 extending arcuately from both rear ends of the panel 2, the cranks 20 including an arcuate portion 21 and a horizontal portion 22.

[0036] The horizontal part 22 is horizontal with the panel 2.

[0037] The horizontal part 22 is provided with a pivot part 3 at its end, and the pivot part 3 is rotatably mounted on both sides of the armrest seat;

[0038] The rear end of the panel 2 is fitted with the guide cavity 4;

[0039] A locking device is provided on both sides of the armrest 1, and the locking device is used to lock the panel 2 when it covers the opening 11;

[0040] When the locking device is unlocked, the panel 2 can be inserted into the cavity 12 under the drive of the elastic element, and its upper part can be extended out.

[0041] In the actual design, by combining the armrest 1 with the cavity 12 and the panel 2 with the opening 11, the panel 2 can be hidden when it is opened. At the same time, when the opening 11 is closed, the armrest 1 and the panel 2 are integrated, which improves the aesthetic design of the furniture.

[0042] In the actual design, the armrest 1 is designed with a guide cavity 4 that abuts against the rear of the panel 2, thereby improving the rotational stability and guiding stability of the panel 2 and enhancing the user experience.

[0043] Specifically, the panel 2 and the crank 20 are integrally formed. Using an integrally formed panel 2 can improve the overall structural stability and reduce assembly steps.

[0044] In this embodiment of the present invention, a guide portion 41 extends rearward from the rear end of the panel 2. The guide portion 41 is in contact with the wall surface of the guide cavity 4, and the guide portion 41 is lower than the upper wall of the panel 2.

[0045] Furthermore, when the panel 2 blocks the opening 11, it abuts against the inner end of the opening 11, wherein the guide part 41 can serve both as a guide and as a limit.

[0046] Specifically, the rear wall of the guide portion 41 is composed of multiple spaced protrusions, and the guide cavity 4 is provided with a guide groove 42 extending along its arc length. The protrusions extend into the guide groove 42, thereby realizing the guidance of the panel 2. Therefore, compared with the existing design, it does not require additional guide structures (such as guide rods), which improves the integration of the design and the stability of the structure, and avoids wear during sliding.

[0047] In this embodiment of the present invention, a protruding strip 7 is provided on the lower wall of the front part of the panel 2. The protruding strip is used to abut against the upper wall of the rear part of the cavity 12, thereby achieving the limitation of the panel 2 when it is in the open state.

[0048] Specifically, the locking device includes elastic locking grooves 51 on both sides of the armrest 1 and a locking bar on the crank 20.

[0049] Both the locking bar and the elastic locking groove extend at an angle, and the locking bar can swing between the position of extending into the elastic locking groove 51 and the position of exiting the elastic locking groove 51. This achieves both unlocking and locking; it also achieves both limiting and locking, and, in conjunction with the guide part 41, reduces the load and pressure on the elastic locking groove 51.

[0050] In this embodiment of the invention, the outer peripheral wall of the pivot portion 3 is provided with a drive gear 31.

[0051] The pivoting part 3 is pivotally mounted to the cavity 12 via a pivot shaft.

[0052] The cavity 12 is provided with driven gears 32 on both sides, which cooperate with the driving gear 31.

[0053] The passive gear 32 is pivotally mounted on the side wall of the cavity 12 and can rotate with the swing of the active gear 31.

[0054] Specifically, the passive gear 32 or the active gear is provided with a torsion spring 6. When the panel 2 swings toward the closed state, the active gear 31 can apply a curling force to the torsion spring 6 and apply pressure to the torsion spring 6.

[0055] When panel 2 is opened, the torsion spring 6 can apply rotational force to the passive gear 32 and drive panel 2 to swing towards the open state, thereby realizing the automatic opening of panel 2.

[0056] In this embodiment of the utility model, a spring plate 61 is also provided on one side of the drive gear 31. The spring plate abuts against the teeth of the drive gear 31 and can make elastic contact under elastic action, thereby providing a damping effect on the drive gear 31. Of course, the specific damping can also be set between the protrusion and the groove. The spring plate can also be achieved by a damping pad, thereby achieving flexible opening and avoiding the problem of the torsion spring 6 bouncing at the moment of opening.

[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
