Description

Technical Field

[0001] This utility model relates to the field of flip-up panel technology, and more specifically, to a flip-up panel and an office chair. Background Technology

[0002] In modern home and office environments, people often need to use laptops or read books on sofas, beds, tables, or chairs to enhance comfort and convenience. As a result, various types of support panels, tabletops, or flip-up panels have emerged. Currently, most of these devices on the market employ simple hinged or flip-up structures.

[0003] However, these existing flip panel structures have many defects: 1) Limited adjustment angle: Most products can only achieve simple folding and unfolding functions, or can only be fixed and adjusted in one direction, which cannot meet the user's needs for the best tilt angle and orientation for different usage scenarios (such as typing, reading, watching movies), resulting in poor applicability and flexibility; 2) Poor structural design: Many products have simple rotating shaft structures and lack reliable axial limit design, which makes the rotating rod or pivot easy to loosen or even fall out of the shaft hole after long-term use, posing safety hazards and affecting service life.

Detailed Implementation

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0036] This utility model provides a flip-up panel, comprising: a base 1, which is mounted on a supporting body, such as an office chair, table, or sofa, and is commonly mounted on an office chair; the base 1 has a rotating engagement part 101; a rotating support member 2, which has a rotating part 201; the rotating part 201 is rotatably connected to the rotating engagement part 101, so that the rotating support member 2 can rotate relative to the base 1 about a first axis; and a panel 4, which is rotatably connected to the rotating support member 2, so that the panel 4 can flip relative to the rotating support member 2 about a second axis. The panel 4 is generally used to place a computer or books, and mainly provides a supporting surface; the second axis does not coincide with the first axis. In one embodiment, the first axis is vertical; the second axis is horizontal, thereby enabling the panel 4 to rotate horizontally and flip vertically, allowing the user to adjust the panel 4 to a position closer to or further away from themselves, and to an angle facing them, thus facilitating reading or operation. An axial limiting structure is provided between the base 1 and the pivot to limit the axial displacement of the pivot in the shaft hole and prevent the pivot from coming out of the shaft hole.

[0037] In one embodiment, such as Figure 7-8 As shown, the flip plate also includes: a pivot connection part 3; the pivot connection part 3 includes a first connector 301 and a second connector 302 that can rotate relative to each other; a rotating support 2 is fixedly connected to the first connector 301; and the plate body 4 is fixedly connected to the second connector 302. The plate body 4 has at least one mounting groove 5 to facilitate the storage of the pivot connection part 3 and the rotating support 2 and to provide them with operating space; the second connector 302 has a mounting arm 303 on at least one side; the mounting arm 303 has a vertical connecting section 303a that extends into the mounting groove 5, and a horizontal connecting section 303b that extends laterally from the vertical connecting section 303a and fits against the surface of the plate body 4; a fastener 303c is fixed between the horizontal connecting section 303b and the plate body 4. The mounting arm 303 can be an integrally formed corner plate, which mainly serves to install the pivot connection part 3.

[0038] In one embodiment, an angle adjustment mechanism is provided within the pivot connection 3 to releasably lock the plate 4 at multiple different angles. The angle adjustment mechanism can be any existing angle adjustment device, as long as it can fix multiple plates 4 at multiple angles. To clearly illustrate the working principle of the angle adjustment mechanism, this utility model uses a conventional embodiment as an example. This angle adjustment mechanism includes a first connecting member 301 and a second connecting member 302 coaxially mounted; there are two first connecting members 301, and as shown... Figure 8 The two first connectors 301 shown are symmetrically arranged on both sides of the second connector 302, and a circular outer shell is also fitted around the first connectors 301. Figure 11As shown, a pair of through grooves are rotationally symmetrically arranged on the second connector 302. One end of the inner wall of each through groove forms an arc-shaped inner wall 3021, and the other end forms two continuous rectangular inner walls 3022. The rectangular inner walls 3022 are inclined. The arc-shaped inner wall 3021 is used to assemble the arc-shaped elastic piece 3023, and the rectangular inner wall 3022 is used to engage the rectangular locking block 3024. One end of the arc-shaped elastic piece 3023 abuts against the rectangular locking block 3024. Figure 10 As shown, the first connector 301 is provided with a pair of arc-shaped guide grooves 3011 for rotational symmetry. The inner wall of the arc-shaped guide grooves 3011 is provided with a plurality of inclined slots 3012. The rectangular block 3024 can be locked in one of the slots 3012. By rotating the first connector 301 or the second connector 302, the rectangular block 3024 can move from one slot 3012 into another slot 3012. Moreover, due to the action of the arc-shaped elastic piece 3023 pressing against the rectangular block 3024, the first connector 301 and the second connector 302 can be fixed at different angles.

[0039] In one embodiment, such as Figure 5-6 As shown, the rotating fitting part 101 is a shaft hole opened on the base 1; the rotating part 201 is a pivot that is rotatably inserted into the shaft hole, so that the pivot can rotate freely in the shaft hole, and the plate 4 can rotate around the axis of the shaft hole; here, the first axis is taken as the vertical direction and the second axis is taken as the horizontal direction. When the plate 4 rotates around the axis of the shaft hole, the orientation or angle of the plate 4 in the horizontal direction can be adjusted. Books, computers and other daily necessities are placed on the plate 4, so that people can easily take the items and view the books, computers and other items from a suitable position / angle.

[0040] In one embodiment, such as Figure 5-6 As shown, the axial limiting structure includes: at least one first annular groove 202 formed on the circumference of the pivot, and an elastic limiting member installed in the first annular groove 202. One, two, or more first annular grooves 202 may be provided. The outer periphery of the elastic limiting member expands radially and abuts against the inner wall of the shaft hole to limit the axial displacement of the pivot. The elastic limiting member is preferably a retaining ring, which, through its own elastic action, holds the pivot in the shaft hole, thus restricting the rotating support 2 within the base 1 and preventing it from coming out, while simultaneously allowing the rotating support 2 to rotate relative to the base 1. Of course, due to the elastic action of the retaining ring, the rotating support 2 experiences some resistance during rotation, but this also allows the rotating support 2 to be relatively fixed at various angles. Furthermore, the elastic limiting member is not limited to a retaining ring, but also includes elastic rings, elastic retaining rings, and other elastic limiting structures capable of radial expansion and contraction.

[0041] In one embodiment, such as Figure 5As shown, the base 1 is provided with a radial flange 102. The radial flange 102 serves two purposes: firstly, to improve the aesthetics of the installation, and secondly, to provide auxiliary support for itself, the rotating support 2, and the plate 4. Below the radial flange 102, there is an external thread 103 for fixed connection with the support body. Here, the outer circumferential surface of the base 1 is a circumferential surface, and the external thread 103 is an external thread provided on the outer circumferential surface of the base 1. When installing the base 1 onto the support body, the base 1 is screwed into the support body for installation and fixation by rotating the base 1. Of course, the base 1 may also be without the radial flange 102 and the external thread 103, and the base 1 may be directly fixed to the support body by welding or other fasteners on the periphery or bottom of the base 1.

[0042] In one embodiment, such as Figure 11-16 As shown, a second annular groove 2011 is provided on the circumference of the rotating part 201; an annular protrusion 2012 is formed by radially protruding inward from the inner wall of the base 1; the annular protrusion 2012 and the second annular groove 2011 are interlocked to form an axial constraint and allow the two to rotate relative to each other in the circumferential direction, mainly to prevent the rotating support 2 from moving axially along the inner wall of the base 1, while ensuring that the rotating support 2 rotates within the base 1; an annular mounting groove 2013 is provided on the outer circumferential area of ​​the base 1 corresponding to the annular protrusion 2012; a radial constraint member 2014 is fitted inside the annular mounting groove 2013 to keep the annular protrusion 2012 and the second annular groove 2011 in a tight fit; the radial constraint member 2014 is provided to prevent the annular protrusion 2012 and the second annular groove 2011 from loosening after long-term use, and the radial constraint member 2014 includes, but is not limited to, the use of snap rings, elastic rubber rings, etc.

[0043] In one embodiment, such as Figure 11-16As shown, a radial boss 2015 is provided on one side of the base 1; several circumferentially distributed arc-shaped elastic blocks 2016 are coaxially arranged on the top of the radial boss 2015. The arc-shaped elastic blocks 2016 include, but are not limited to, those made of rubber, to facilitate engagement with the second mounting plate 2017; the second mounting plate 2017 is sleeved on the circumference of the rotating support 2; the second mounting plate 2017 is provided with a third annular groove 2018; the inner wall of the third annular groove 2018 engages with the arc-shaped elastic blocks 2016 to fix the base 1 and the second mounting plate 2017; a sleeve 2019 is also sleeved on the circumference of the base 1; a first mounting plate 2020 is fixedly connected to the circumference of the sleeve 2019. The first mounting plate 2020 has mounting holes for bolt and nut assemblies to pass through, facilitating the fixing of the first mounting plate 2020 to the support body; the first mounting plate 2020 is fixedly connected to the support body. Several connecting grooves 2021 are provided around the base 1; an elastic protrusion 2022 that can move radially along the base 1 is fixed on one side wall of the connecting groove 2021. This serves two purposes: first, it facilitates the sleeve 2019 to be fitted upwards around the base 1; second, it facilitates the top of the elastic protrusion 2022 to support the sleeve 2019 after it is fitted into the base 1.

[0044] In one embodiment, such as Figure 1 and 9 As shown, the plate 4 includes an upper cover 401 and a lower cover 402 that interlock with each other. The upper cover 401 has a snap-fit ​​portion 403 along its inner peripheral wall, which consists of multiple snap-fit ​​holes. The lower cover 402 has a snap-fit ​​mating portion 404 along its outer peripheral wall that mates with the snap-fit ​​portion 403, which consists of multiple snap-fit ​​blocks. Alternatively, the snap-fit ​​portion 403 can consist of multiple snap-fit ​​blocks, and the snap-fit ​​mating portion 404 can consist of multiple snap-fit ​​holes. Of course, the upper cover 401 and the lower cover 402 are not limited to the above-mentioned snap-fit ​​block and snap-fit ​​hole mating. In addition, the upper cover 401 has a stop block along its upper surface edge to prevent books or computers and other items from falling off when the plate 4 is tilted. In addition, the upper surface of the lower cover 402 is also provided with reinforcing ribs in the longitudinal and transverse directions to form a grid structure to improve the strength of the plate 4. The surface of the lower cover 402 is also provided with multiple heat dissipation holes so that electronic devices such as computers placed on the upper cover 401 can dissipate heat through the heat dissipation holes.

[0045] This utility model also provides an office chair, including the aforementioned flip panel. By rotating the flip panel horizontally and flipping it vertically, users can adjust the panel to a suitable tilt angle and orientation, making it convenient for people to comfortably use books or computers on the panel while sitting in the office chair.

[0046] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
