Abstract
Description
TECHNICAL FIELD
[0001] The present invention relates to a new executive chair with a rotatable desk board for students, office workers and the elderly, which allows eye and spine pressure-free during long learning / working process, and the height of the chair and desk can be adjusted. Executive chairs are usually equipped with air pressure lifting devices to easily adjust the height of the seat, and equipped with rollers for easy movement, but not equipped with a connected desk board, which has been a demand that has not been met by students and computer workers! BACKGROUND
[0002] There is no executive chair on the market with an easy-to-use desk board. The combination of existing executive chairs and independent desks has defects that are inconvenient for students and computer or office workers. When using, the executive chair needs to be pulled back, sit down and lean forward on the desk to read. When you need to change books for learning, you need to pull the chair away, get up and walk to get a new book. The executive chair with a desk board of the present invention not only has lower cost and less material usage, but also helps to improve the sitting posture. The present invention provides a novel, simple and more easily pushed or pulled desk board, and books can be placed directly on the desk. The present invention makes reading and learning more convenient, while avoiding spine bending and eye fatigue. Some executive chairs with side writing boards have small writing boards that need to be handled carefully to prevent books or laptops on the writing board from sliding or falling. With the gradual elimination of desktop computer hosts, the new executive chair combined with the present invention and a small desk board of suitable size can help laptop users and students learn.
[0003] TECHNICAL PROBLEM
[0004] The existing separate executive chair and desk have the following defects in use:
[0005] 1. Pull the executive chair back, stand in front of the desk, then pull the chair close to the desk and sit down.
[0006] 2. After reading, you need to get up, roll the chair back, get a new book / notebook and place it on the desk.
[0007] 3. Roll the chair to the desk again, adjust the height of the chair and sit down to learn.
[0008] 4. Most children and adults will bend their spines when sitting, which will cause damage to the eyes and spine.
[0009] 5. Concentration can easily decrease quickly, resulting in reduced learning ability.
[0010] For the new research on executive chairs with desk boards, engineering innovation and new ideas are needed:
[0011] 1. The chair and the desk must be able to move as a whole when the position is changed.
[0012] 2. As the gas pressure lifting device adjusts the height of the chair, the table must also be raised or lowered simultaneously.
[0013] 3. The table should be located in front during study and on the side during rest.
[0014] 4. The table should be easily moved with minimal force.
[0015] 5. Optimal materials should be used to achieve low cost, easy use, and sustainable use for many years.
[0016] 6. The chair-table integrated structure must reduce the pressure on the eyes and spine compared to the separate chair and table.
[0017] 7. Executive chairs equipped with side writing boards are not a solution because there is limited space for study, and books must be removed before moving the writing board to prevent books or laptops from falling.
[0018] 8. Users generally need a cup holder, storage space, and a desk size suitable for placing laptops and books, meeting the needs of long working hours.
[0019] 9. The present invention addresses the problems of the above-mentioned chair and table and solves them through innovative engineering design using simple components. Simplicity itself is an invention! The structural components used are novel, creative, and practical, addressing the long-standing need for comfort and long-term use by students and staff.
[0020] Solution to the problem
[0021] The present invention provides a new executive chair equipped with a connected table board that can be rotated from the front to the side, facilitating multitasking and reducing learning / work fatigue, and is a more convenient solution:
[0022] 1. Place books, notebooks, and laptops on the connected table board to meet the planned study duration.
[0023] 2. Sit on the chair, pull the table board with wheels to the front, and adjust the height of the chair and table board simultaneously.
[0024] 3. After studying, place the used books / notebooks back and take new ones to continue studying.
[0025] 4. After the study is completed, push or roll the table board away, requiring less force / energy.
[0026] 5. The table board can be rolled and moved with the chair to any location.
[0027] The new executive chair can benefit students and adults by keeping books and eyes at a safe distance and keeping the spine straight, thus forming a correct sitting posture. Equipping a writing board is not an effective solution. We have searched online stores in various countries, including IKEA, Walmart, Mayfair, Amazon, and Alibaba, and have not found an executive chair product equipped with a connected desk board. We have also searched furniture associations in India, the United States, the European Union, China, South Korea, and Japan, and have not found such a product or classification. Existing patents on writing boards and chairs do not belong to the technical field of executive chairs equipped with desk boards, and cannot be used as the basis for priority for this invention. Executive chairs equipped with connected desk boards now constitute a new product category. A few patents related to chair improvements (but none of which involve a desk board that can be moved from the front to the side and its height adjustment) include:
[0028] 1. US2008231091, WEBER R, Combination desk and chair, but not an executive chair, and no rollers.
[0029] 2. US2008231091, 2008-09-25, GORANSON PATRICK ALLEN, Side-mounted compact writing board mounting structure, but there is no real desk board. The invention has a desk board with an inclined surface that is more comfortable to use than a writing board!
[0030] 3. US5653499, 1997-08-05, GOODALL KIRK BRYANT, Chair support for supporting keyboard and mouse platform, this structure is a chair with a fixed support, but there is no desk board.
[0031] Therefore, the purpose of the invention is to propose a solution to reduce the cost of an executive chair and its connected desk board that can be used for a long time. The invention is an investment for improving sitting posture, allowing users to learn or work for a long time in a more relaxed way and is suitable for long-term use. Extensive searches have been made through the Internet and relevant patent specifications have been studied to find executive chairs equipped with rotating desk boards. Since the invention has a fundamental difference in using a new executive chair equipped with a rotating and variable-height desk board, the inventor could not find a patent specification that could be cited in existing databases. Searches of the United States Patent and Trademark Office (USPTO), the European Patent Office, and other relevant agencies, as well as existing literature, executive chair and desk production company materials, have not found a device similar to the invention. There is no executive chair with a new connection structure and a rotating (not rotating around its own axis) desk board as a citable prior art in the existing technology. SUMMARY
[0032] This new executive chair includes a chair body with casters, a seat, and a backrest for supporting the spine, maintaining proper posture, and providing comfortable support. For right-handed users, the chair has a connecting structure at the front left corner of the seat. This structure includes a cylinder with a bushing inside, where one leg of the tabletop is housed, facilitating rotation of the tabletop with the right hand. For left-handed users, a tabletop connecting structure is located at the front right corner of the seat, allowing the tabletop to move to the right. The pivot leg has casters at its bottom for movement. The tabletop also has another leg with casters or rollers at its bottom for further movement. The tabletop has only two legs: one for pivot connection and the other a swivel leg with casters. A transverse connecting arm secures these two legs. These legs support a transverse tabletop support tube with an adjustable upper section. The tabletop body is mounted on this support tube. In use, the user sits in the chair, pulls the tabletop forward, adjusts the tilt angle and height, places books, and begins studying. The chair also features attachments for placing water, coffee, or snacks, preventing spills or messes onto the desktop while the user is studying. This invention is a height-adjustable chair-table combination structure with low table costs, saving users on furniture expenses, while its excellent ergonomic design helps maintain good spinal and vision health.

[0041] The following description outlines the significant features, construction methods, usage methods, and advantages of this invention.
[0042] This new device provides a novel executive chair equipped with a connecting table that can be rotated from the front to the side.
[0043] This invention offers both a comfortable work / study experience and a pleasing appearance. Existing executive chairs and separate desks have long lacked improvement. The pneumatic height adjustment mechanisms of such chairs typically have three height ranges: 10, 15, and 25 cm. The tabletop must also be able to move accordingly within this range. The purpose of this invention is to overcome the inherent defects in the usability and cost of existing separate executive chairs and desks. To this end, we have created this new invention. The executive chair and desk structure of this invention is superior, convenient to use, easy to maintain, and saves money, time, and is beneficial to health. This invention is not a simple workshop improvement, but is based on long-term research, including changing the tabletop structure from four legs to two legs, and conducting in-depth research on the ideal connection structure for achieving good support and smooth rotation. The height adjustment and tilt angle of the tabletop have also been studied and resolved. Given the long-standing failure of furniture companies worldwide to address the urgent need for ergonomic chairs among students and workers, this invention possesses both non-obviousness and novelty.
[0044] The present invention comprises: 1. an executive chair with a novel bushing connection structure at the front edge of the seat; 2. a two-legged table frame for rotating the tabletop from the front to the side; 3. a table frame structure for supporting the tabletop, allowing the tabletop to be adjusted to multiple tilt angles for a comfortable reading view; and 4. adjustable height for both the chair and the tabletop to achieve comfort and save the cost of purchasing a new chair. All four components are novel, possess new functions, and bring improved work / study experiences to all users in this executive chair and table combination. For ease of explanation, we use common terms such as legs, connection structure, panel, flange, bolt, etc.
[0045] This novel device reduces physical exertion during work / study, alleviates stress from prolonged study, and maintains a safe eye distance and spinal posture.
[0046] The new executive chair according to the invention is superior because of its compact structure and ease of use for children or adult staff.
[0047] This invention includes an executive chair (see Figure 1 It has a seat, backrest, pneumatic lifting device (22), pneumatic adjustment handle (26), and multiple casters for rolling. The seat has a connecting structure (3) at the front left corner (see...). Figure 2), used to securely fix and facilitate right-handed users to rotate the tabletop (2). For left-handed users, this connection structure can be located at the right front corner of the seat. This specification shows the structure for right-handed users. For left-handed users, only its mirror structure needs to be considered, that is, a pivot structure for rotating the tabletop to the right is provided at the right front corner of the seat. The connection structure includes a component (5) fixed to the seat (see Figure 2 The chair comprises two vertical members (6) and a tube (7) for housing the bushing. The bushing (8) is a plastic tube, such as polypropylene or nylon. The vertical members are two plates with multiple holes (32). These holes are used to fix or disassemble the connecting structure via bolts (33) for bushing replacement. Inside the bushing (8), the pivot leg (9) allows for quiet and low-friction rotation, enabling long-term use. The bushing also allows the connecting structure to move up and down with the executive chair during height adjustment, while the pivot leg is stably supported on the ground.
[0048] On the other side of the connecting structure, the tabletop leg (9) is fixed inside the bushing; this leg is called the pivot leg. The pivot leg contacts and is supported on the ground via its casters (10). The table frame also has another wheeled leg (11), called the swivel leg, which has rollers (12) at its bottom for rolling on the ground. A lower horizontal tube (13) (see...) Figure 2 The pivot leg (11) is used to secure and connect the two legs, allowing the tabletop to rotate stably forward or sideways within the bushing connection structure. The pivot leg stabilizes the table frame, while the swivel leg (11) can roll from the side to the front of the chair. An upper central tabletop support tube (14) is provided at the upper end of each of the two legs (see...). Figure 2 , Figure 3 ), used to fix the desktop panel (2). The two ends of the support tube (14) are provided with curved long tubes (15) (see Figure 2 The lower tube (15) is provided with a series of holes (30). The lower tube (15) is fixed to the interior of the pivot leg (9) and the rotating leg (11) with wheels, respectively. The lower tube (15) is provided with a series of holes (30). The lower tube (15) is fixed to the interior of the pivot leg (9) and the rotating leg (11) by spring clips or bolts (27). After releasing the clips (27) or bolts, the desktop can be raised or lowered to a suitable height. Spring clips are preferred over unscrewing bolts and tightening nuts. The writing / study panel (2) is made of wood / plastic / metal and has two rings or clamps (24) at the bottom for fixing to the upper desktop support tube (14). The clamps (24) are used to fix the desktop and help to adjust the height and tilt angle of the writing / study panel 2 to achieve a comfortable reading angle. Flanges (17) are provided on both sides of the desktop support tube (14) (see Figure 2The flange (17) is used to support the learning panel (2). The flange has threaded holes and is equipped with bolts (16) for adjusting the height and tilt angle of the desktop. When the bolts are screwed in, the rear of the panel (2) is raised, creating a suitable tilt angle for reading books; when the bolts are unscrewed, the panel remains horizontal for use with a laptop. The bolt heads can be designed with a flat structure for easy rotation, thus allowing for height adjustment of the panel (2) on the flange (17). This small tilt angle is beneficial for reading books.
[0049] As an alternative, the tabletop and legs are provided with rings (27) on the sides of the panel body (2) and on the legs (9, 11) (see Figure 3 ), used in conjunction with the bottom tilt bar (28), to stably fix the desktop learning panel (2) during use. Two tilt bars can be provided on each side of the table to achieve stable and firm desktop support.
[0050] The tilting rod (28) in its simplified form is a hook-shaped structure used to connect with the ring on the table leg. The tilting rod structure is as follows: Figure 3 As shown. Figure 2 As shown, the flange (17) with bolts (16) is used to raise and lower the desktop, thereby facilitating the adjustment of the desktop tilt angle and making it easy to use. This tilting mechanism helps to provide solid support for the desktop during study and achieves a tilt angle that is conducive to eye comfort.
[0051] The tabletop has a front locking mechanism (18) on the front side (see...) Figure 2 , Figure 5 Its form can be magnetic strip, short chain, bolt, padlock, or hook structure, used to fix the table frame to the chair during study to prevent the table from being accidentally pushed. This structure also constitutes a safety device. In addition, a rear lock (19) is provided. Figure 1 As shown, the rear lock is a short chain located on the back of the seat. When not in use for studying, it securely fastens the tabletop to the side of the chair, allowing the chair and tabletop to roll together as a single unit. Figure 7 In the middle, the rear lock (19) is a small magnetic disc structure.
[0052] like Figure 2 As shown, the coffee and snack holder (20) can be installed on the side of the desktop, near the chair, or on the table leg to prevent spills on the writing and learning panel (2). The tilt angle of the writing desktop can be adjusted by adjusting the tilt mechanism of the panel support.
[0053] like Figure 6As shown, the tabletop can also be equipped with a lockable storage shelf (21) for storing items. Additionally, a wheeled support leg (31) can be added to support the weight of the additional storage device, thus enabling stable and smooth rotation of the tabletop during office use. The vertical component (6) of this connecting structure can consist of two parts and is provided with holes (32) and bolts (33) (see...). Figure 2 This facilitates the fixing or disassembly of the connecting structure, thereby making it easier to replace the bushing or transport the chair and table assembly.
[0054] When using, place the required books, notebooks, and laptops on the desktop (2). Figure 1 As shown, the table is located on the side of the chair. Sit in the executive chair, adjust the seat height, and pull the table forward (as shown). Figure 4 As shown), by releasing or fixing the buckle (27), the horizontal tabletop support tube (14) and its two side tubes (15) can move up and down within the two legs (9, 11) of the table frame to adjust the tabletop height, thereby achieving a suitable eye distance and keeping the spine straight. Figure 2 As shown, the flange bolts (16) on both sides can be used to increase the tilt angle of the desktop to improve eye comfort. Lock the front lock (18) to the front of the chair, as shown. Figure 4 As shown. Place the book / notebook / laptop on the table for studying and writing. For clarity, the book is not shown in any of the accompanying drawings. Then, release the table and chair lock (18) to leave for next use. The chair and backrest provide good back support. Figure 1 and Figure 4 The tabletop is shown in its position relative to the side or front of the chair for easy reading. Compared to traditional separate chairs and tables, the tabletop requires less force to move via the casters, eliminating the need to repeatedly pull the chair.
[0055] exist Figure 7 The tabletop features a pneumatic lifting device (22), a pneumatic adjustment handle (26), casters (29), and a lockable storage tray (21). A pivot rod (23) is located at the bottom of the tabletop for insertion and rotation within a bushing (8) of the connecting structure. A lock (18) is provided on the tabletop to secure it to the front of the chair for stable use in the forward learning position. Another rear lock (19), a circular magnetic piece, is located on the rear side of the seat for locking when the tabletop is in the side position. The pneumatic lifting devices of the chair and tabletop can be simultaneously raised or lowered via the handle (26) to adjust to a suitable height.
[0056] Metal tubing for the chair and table frame is cut according to the different component dimensions and connected by welding or bolting, as shown in the figure. The seat is installed on the executive chair, the pneumatic lifting device and casters are installed, the writing panel is fixed to the top of the table frame, the connecting structure is installed on the chair body, and the pivot legs of the tabletop are inserted into the bushing (8). The tabletop can be easily rotated from the side to the front in this connecting structure. The tabletop (2) is fixed to the upper transverse support tube (14) by the tabletop clamp (24). The transverse support tube with the side-down tube (15) is fixed inside the two table legs (9, 11). The metal tubing is cut according to the size and strength requirements and is installed according to the dimensions and strength requirements. Figure 2 The manufacturing process is as shown.
[0057] For children's chair and table sets, plastic tubing can also be used, and the connecting structure can be fixed to the front of the chair and the pivot legs of the tabletop by bolts or adhesive.
[0058] This device can be modified. The seat can be made of plastic, foam for cold climates, or wood or porous metal for hot climates. The backrest, neck and lumbar support, seat tilt design, and shape can all be varied. The chair is firmly placed on the ground, and the tabletop rotates between the side and front via a bushing connection structure and moves quietly via casters for study / work use. The pivot legs (9) of the tabletop rotate within the bearing tubes (8), allowing the tabletop to be moved to the front of the chair or slid to the back, thus saving space. The desktop writing and study panel (2) can be made in different sizes, from single book or notebook size to size for multiple books, drawing size, or larger size for books, notebooks, and laptops, to meet office use needs. Different sizes of chair-table combinations can be designed for adults and children of different ages. The tabletop can be designed as a three-part structure, including a central body and two side panels that can be folded down or raised and locked to form a larger desktop. This rotating tabletop is suitable for various functions, such as dining, writing, or using electronic devices, making it a versatile configuration for chairs in office, home, or leisure environments. Its smooth and adjustable rotation mechanism allows users to adjust the tabletop to different angles relative to the chair according to personal preference and activity needs. Alternatively, a lower tube (15) can be located on the outside of the pivot legs and wheeled legs, which have a series of holes, and clips mounted on the lower tube can be used to lock and support the tabletop. The gap between the bushing and the pivot legs facilitates tabletop rotation and chair height adjustment.
[0059] Advantages of this invention:
[0060] 1. The tabletop adopts a two-leg structure, including a pivot leg (8) and a wheeled rolling leg, instead of the traditional four-legged table structure, thus saving material costs.
[0061] 2. The force required to push or pull the wheeled tabletop is less than the energy required to move a chair or table.
[0062] 3. The height and tilt angle of the tabletop are adjustable, which is beneficial to eye and spinal health and suitable for long-term study.
[0063] 4. Maintaining a safe eye distance and an upright posture can reduce the risk of developing spinal inflammation or needing to wear glasses later in life.
[0064] 5. A comfortable sitting posture combined with easy book changing helps to enable longer and more enjoyable learning sessions.
[0065] 6. Children, teenagers, and adults can all benefit from this for a long time while studying or working.
