Description

Technical Field

[0001] This invention relates to the field of integrated table and chair technology, specifically to a movable integrated table and chair with adjustable angle. Background Technology

[0002] Integrated desks and chairs provide a comfortable working or studying environment by combining a desktop and a chair. When used for studying, the integrated desks and chairs also need to maintain stability and provide appropriate comfort for rest. However, there are still some problems with the use of existing integrated desks and chairs in the learning environment.

[0003] In the prior art, the patent publication (announcement) number CN106539320B describes a "multifunctional integrated table and chair" which includes a base plate and a tabletop and chair panel mounted on the base plate. The tabletop is connected to the base plate via a first linkage mechanism. The first linkage mechanism includes an upper linkage and a lower linkage that are hinged to each other at their ends. The top end of the upper linkage is hinged to the tabletop, and the bottom end of the lower linkage is hinged to the base plate. The bottom surface of the tabletop is also provided with several teeth. One end of the upper linkage is hinged to an adjustment bracket. The other end of the adjustment bracket is pressed against different teeth to maintain different angles of the tabletop.

[0004] During the operation of the above-mentioned device, the design is reasonable, integrating functions such as theoretical teaching, various mechanical drawing teaching, and diverse painting teaching into one, so that a table and chair can have multiple classroom use functions at the same time. Moreover, the structure of the invention is simple and easy to operate. However, when adjusting the chair during use, it is necessary to manually adjust the positioning, which is very easy to cause inaccurate positioning and requires multiple adjustments, making it inconvenient for students to quickly adjust and rest.

[0005] In the prior art, the authorized publication (announcement) number: CN116098391A, "A movable integrated table and chair with adjustable angle", relates to the field of table and chair application technology, including a table and chair base, with chair legs on both the left and right sides of the upper rear of the table and chair base, a chair seat on the upper end of the two chair legs, seat handles on both the left and right sides of the upper end of the chair seat, and an adjustable backrest at the upper rear of the chair seat;

[0006] In the prior art, the patent publication (announcement) number CN113317644A, entitled "A movable integrated table and chair with adjustable angle", includes a chair leg assembly and a support assembly fixed on the chair leg assembly. The support assembly is vertically arranged, and a table board assembly is provided at the top of the support assembly. A seat assembly is provided above the chair leg assembly, and the seat assembly is located at the rear end of the support assembly.

[0007] During the operation of the above-mentioned device, the height adjustment of the table and chair and the depth adjustment of the chair are effectively realized by the cooperation between the various structures, which ensures the convenient use of the integrated table and chair. At the same time, the structure provided by the present invention has a reasonable combination and significant implementation effect, making it suitable for large-scale promotion and use. However, when using the adjusted chair back and the leg support to be too flat, and lying down or sitting, it is easy to cause muscle soreness and numbness and affect blood circulation. In addition, the adjustment requires gradual control, which is cumbersome and inconvenient to effectively control the comfort of use. Summary of the Invention

[0008] The purpose of this invention is to provide a movable integrated table and chair with adjustable angle, in order to solve the problems mentioned in the background art. When adjusting the chair, manual adjustment is required, which is prone to inaccurate positioning and requires multiple adjustments, making it inconvenient for students to quickly adjust and rest. In addition, the adjusted chair back and leg support are too flat, which can easily cause muscle soreness and numbness when lying down or sitting, and affect blood circulation. Furthermore, the adjustment requires gradual control, which is cumbersome and inconvenient to effectively control the comfort of use.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a movable integrated table and chair with adjustable angle, which is equipped with a desk for easy use in class, and a telescopic seat for connecting a corresponding seat frame is provided on the left side of the outer surface of the desk;

[0010] Includes: table legs, telescopically connected to the lower surface of the desk, and a base is installed on the lower surface of the table legs, with rollers rotatably connected to the inner surface of the base, and a spur gear rotatably connected to the middle section of the inner surface of the base;

[0011] A first movable rod is nested and connected to the inner surface of the base, and a limit strip is installed on the outer surface of the first movable rod, which limits the sliding of the limit strip on the inner surface of the base. A rack is installed on the lower surface of the first movable rod, and a spur gear is meshed on the lower surface of the rack. Meanwhile, a second movable rod is connected to the lower surface of the spur gear through the rack, and a movable block is installed at the outer end of the first and second movable rods.

[0012] A sliding rod is slidably connected to the upper side of the inner surface of the seat frame, and a movable shaft is rotatably connected to the inner surface of the sliding rod. A scissor-type support frame is installed on the outer surface of the movable shaft, and the movable shaft is slidably mounted on the inner surface of the seat frame through the scissor-type support frame. At the same time, a telescopic seat is assembled on the upper surface of the scissor-type support frame, and a limit rod is slidably connected to the inner surface of the telescopic seat, and the limit rod is installed on the upper surface of the seat frame.

[0013] The movable part is slidably connected to the inner surface of the telescopic seat, and the inner surface of the movable part is threadedly connected to a threaded rod, and the outer surface end of the threaded rod is nestedly connected to a first bevel gear, while the outer surface of the first bevel gear is meshed with a second bevel gear.

[0014] A connecting rod is rotatably connected to the upper surface of the moving part, and a backrest is rotatably connected to the upper surface of the connecting rod. The lower middle section of the backrest is rotatably assembled on the left side of the outer surface of the telescopic seat, and a seat cushion is attached between the backrest and the telescopic seat.

[0015] An extrusion rod is installed on the right side of the outer surface of the movable part, and a push rod is rotatably connected to the outer side of the extrusion rod. A bracket is rotatably connected to the other end of the outer surface of the push rod. Meanwhile, a support plate is connected to the right side of the outer surface of the bracket, and a reinforcing rod and a locking block are installed on the outer surface of the support plate. The reinforcing rod and the locking block are nested and locked into the inner surface of the bracket.

[0016] Preferably, the desk has a telescopic structure formed by the legs and the base, and the base and the rollers form a built-in rotating structure. The base has a meshing moving structure with the first moving rod and the second moving rod through a spur gear and a rack. At the same time, the first moving rod and the second moving rod have an integrated structure with the limiting strip, the rack and the moving block, respectively. Furthermore, the first moving rod and the second moving rod have a limiting sliding structure with the base through the limiting strip, and the lower surface of the moving block has an inclined shape.

[0017] With the above structure, the desk can be effectively extended and adjusted during use, and its movement can be controlled. The spur gears inside the assembly control the engagement of the first and second moving rods, thereby improving the stability of the device.

[0018] Preferably, a positioning block is pressed and connected to the lower surface of the movable block, and side plates are installed on the left and right sides of the outer surface of the positioning block. Sliders are installed on the front and rear sides of the outer surface of the positioning block, and the sliders are limited to slide on the inner surface of the base. At the same time, a compression spring is clamped and connected between the base and the side plates.

[0019] The above structure facilitates effective positioning and assembly during use, and the compression spring enables elastic sliding, thereby controlling the height of the positioning block.

[0020] Preferably, the positioning block forms a limiting sliding structure with the base through a slider, and the base forms an elastic structure with the positioning block through a compression spring and a side plate, and the upper surface of the positioning block is in contact with the lower surface of the moving block.

[0021] With the above structure, it can effectively cooperate with the pressing and squeezing during use, control the positioning block to form a downward movement under pressure, and cooperate with the compression spring to control the movement position of the positioning block after being pressed, and form an automatic reset when not under pressure.

[0022] Preferably, the seat frame and the slide rod form a threaded adjustment limiting movement setting, and the slide rod forms a rotating structure with the scissor support frame through the moving shaft, and the scissor support frame forms a sliding structure with the telescopic seat and the seat frame through the moving shaft, while the seat frame forms a telescopic structure with the telescopic seat through the limiting rod.

[0023] The above structure facilitates effective limit sliding adjustment during use, thereby controlling the cross-expansion of the scissor-type support frame and thus controlling the height of the movable seat.

[0024] Preferably, the movable component forms a threaded adjustment limiting sliding structure with the telescopic seat via a threaded rod, and the threaded rod forms a meshing structure with the first bevel gear and the second bevel gear. The threaded rod, the first bevel gear and the second bevel gear are equidistant from the inner surface of the telescopic seat. At the same time, the movable component forms a positioning rotation structure with the backrest via a connecting rod, and the backrest and the telescopic seat are fitted together with the seat cushion.

[0025] With the above structure, the position of the moving part can be effectively adjusted by the thread during use, and the assembled threaded rod can improve the stability of use. The first bevel gear and the second bevel gear connected by the threaded rod can control the stability of the moving rod adjustment and adjust the angle of the backrest.

[0026] Preferably, the extrusion rod and the moving part form an integrated structure, the extrusion rod and the push rod form a rotating structure, and the push rod and the bracket form a positioning and rotating structure. At the same time, the bracket forms a limiting and engaging structure with the support plate through the reinforcing rod and the locking block.

[0027] The above structure facilitates the effective formation of a rotating structure during use, allowing for the rotation control of the bracket's angle. Furthermore, the bent structure of the push rod effectively increases the angle of the support plate on the bracket.

[0028] Preferably, an extrusion roller is rotatably connected to the inner surface of the extrusion rod, and a support rod is installed on the upper surface of the extrusion rod, limiting the sliding of the support rod on the inner surface of the telescopic seat. An extrusion block is attached to the upper surface of the extrusion roller, and an inclined plate is installed on the upper surface of the extrusion block, with the inclined plate nested and rotatably positioned in the middle section of the inner surface of the telescopic seat.

[0029] The above structure facilitates stable nested rotation assembly during use, thereby contacting the extrusion block to form extrusion and controlling the angle of the inclined plate. This provides a certain angle support for the lower part of the buttocks, preventing slippage during rest.

[0030] Preferably, the extrusion roller and the extrusion rod form a built-in rotating structure, and the outer surface of the extrusion rod is inclined. The extrusion rod and the extrusion block form a sliding extrusion structure through the extrusion roller and the support rod. At the same time, the extrusion block and the inclined plate form an integrated structure, and the lower surface of the extrusion block is arc-shaped.

[0031] The above structure effectively improves the stability of the extrusion roller adjustment during use, and, in conjunction with the assembled extrusion rod, controls the angle of the inclined plate on the extrusion block.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. This adjustable movable integrated table and chair set features table legs and a base for easy assembly, which support and extend the tabletop. The base has built-in movable casters and works in conjunction with an adjustable first and second moving rod. These rods, along with a moving block, press against a positioning block to position the table and prevent movement during use. The seat frame also features a movable positioning structure to enhance ease of use.

[0034] 2. This adjustable movable integrated table and chair is equipped with spur gears and racks for easy meshing and adjustment. It effectively moves the first and second moving rods and drives the moving block to press against the positioning block, thereby controlling the up and down movement of the positioning block and providing positioning support for the desk and chair frame to prevent slippage. In conjunction with the elastic cooperation of the side plate and the compression spring, it controls the positioning block to return to its original position and allows for adjustment of the position of the desk and chair frame.

[0035] 3. This adjustable movable integrated table and chair features an adjustable scissor-type support frame with an angle that controls the height between the seat frame and the telescopic seat. During adjustment, a limit rod is used to control the stability of movement, thereby controlling the height of the telescopic seat and improving user comfort. The adjustable moving parts and threaded rod, along with the engagement of the first and second bevel gears, effectively control the angle of the connecting rod, thereby adjusting the angle of the backrest.

[0036] Furthermore, during the adjustment of the moving parts, the squeezing rod, together with the squeezing tube and the support rod, simultaneously drives the squeezing rod to form a limiting slide on the upper side of the inner surface of the telescopic seat, and forms a squeezing fine adjustment angle on the inclined plate installed on the squeezing block, thereby controlling the support for the buttocks when the user is sitting or semi-reclining, thus preventing the buttocks from sliding and improving the comfort during use. In addition, the "L"-shaped seat cushion on the telescopic seat improves the stability during use.

[0037] Furthermore, during the adjustment of the moving parts, the angle of the bracket is controlled by the synchronously rotating push rod. The outer surface of the push rod has a bent structure, which effectively increases the angle of the bracket while controlling the support plate to support the user's legs. It also effectively makes the seat body a comfortable use state with adjustable height and angle. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1-7 The present invention provides a technical solution: a movable integrated table and chair with adjustable angle, which is provided with a desk 1 for easy use in class, and a telescopic seat 15 connected to a corresponding seat frame 11 is provided on the left side of the outer surface of the desk 1;

[0048] Includes: table legs 2, which are telescopically connected to the lower surface of the desk 1, and a base 3 is installed on the lower surface of the table legs 2, and a roller 4 is rotatably connected to the inner surface of the base 3, while a spur gear 5 is rotatably connected to the middle section of the inner surface of the base 3.

[0049] The first moving rod 6 is nested and connected to the inner surface of the base 3, and the outer surface of the first moving rod 6 is equipped with a limiting strip 7, which limits the sliding of the limiting strip 7 on the inner surface of the base 3. The lower surface of the first moving rod 6 is equipped with a rack 9, and a spur gear 5 is meshed and connected to the lower surface of the rack 9. The lower surface of the spur gear 5 is connected to the second moving rod 8 through the rack 9. The outer ends of the first moving rod 6 and the second moving rod 8 are equipped with moving blocks 10.

[0050] The slide rod 12 is slidably connected to the upper side of the inner surface of the seat frame 11, and the inner surface of the slide rod 12 is rotatably connected to the moving shaft 13. The outer surface of the moving shaft 13 is equipped with a scissor-type support frame 14, and the moving shaft 13 is slidably mounted on the inner surface of the seat frame 11 through the scissor-type support frame 14. At the same time, the upper surface of the scissor-type support frame 14 supports and assembles a telescopic seat 15, and the inner surface of the telescopic seat 15 is slidably connected to a limit rod 16, and the limit rod 16 is mounted on the upper surface of the seat frame 11.

[0051] The desk 1 has a telescopic structure formed by the legs 2 and the base 3, and the base 3 has a built-in rotating structure formed by the rollers 4. The base 3 has a meshing moving structure with the first moving rod 6 and the second moving rod 8 through the spur gear 5 and the rack 9. At the same time, the first moving rod 6 and the second moving rod 8 have an integrated structure with the limiting strip 7, the rack 9 and the moving block 10, respectively. The first moving rod 6 and the second moving rod 8 have a limiting sliding structure formed with the base 3 through the limiting strip 7, and the lower surface of the moving block 10 has an inclined shape.

[0052] The lower surface of the movable block 10 is pressed and connected to the positioning block 1001, and the left and right sides of the outer surface of the positioning block 1001 are equipped with side plates 1002, and the front and rear sides of the outer surface of the positioning block 1001 are equipped with sliders 1003, which limit the sliders 1003 to slide on the inner surface of the base 3. At the same time, a compression spring 1004 is clamped and connected between the base 3 and the side plates 1002.

[0053] The positioning block 1001 forms a limiting sliding structure with the base 3 through the slider 1003, and the base 3 forms an elastic structure with the positioning block 1001 through the compression spring 1004 and the side plate 1002, and the upper surface of the positioning block 1001 is in contact with the lower surface of the moving block 10.

[0054] The seat frame 11 and the slide rod 12 form a threaded adjustment limit movement setting, and the slide rod 12 forms a rotating structure with the scissor support frame 14 through the moving shaft 13. The scissor support frame 14 forms a sliding structure with the telescopic seat 15 and the seat frame 11 through the moving shaft 13. At the same time, the seat frame 11 forms a telescopic structure with the telescopic seat 15 through the limit rod 16.

[0055] In use, the height of the desk 1 can be adjusted via the table legs 2 mounted on the base 3. The position of the desk 1 can be stably controlled by the rotating casters 4 mounted on the base 3. When positioning the desk 1 is required, the motor inside the base 3 can be adjusted, and its output shaft drives the spur gear 5 to rotate. This causes the spur gear 5 to mesh with the rack 9, thereby controlling the engagement and deployment of the first and second moving rods 6 and 8 mounted on the rack 9. The first and second moving rods 6 and 8 form a limiting sliding structure to prevent tilting. The casters 4 mounted on the first and second moving rods 6 and 8 further contribute to this adjustment. The moving block 10 effectively compresses the positioning block 1001. During compression, the positioning block 1001, in conjunction with the installed slider 1003, can slide within the inner surface of the base 3, thereby compressing the compression spring 1004 connected to the lower side of the side plate 1002 installed on the side of the positioning block 1001. This controls the positioning block 1001 to contact the ground and form a stable support. In the future, when the position of the desk 1 needs to be adjusted, the moving block 10 can be effectively reset. In conjunction with the compression spring 1004, the positioning block 1001 can be moved upward and reset, improving the stability of the device.

[0056] When adjusting the height of the desk 1, the motor built into the seat frame 11 can be controlled according to the usage situation. The slide rod 12 is adjusted by the lead screw to form a limit slide. When the slide rod 12 slides, it can drive the scissor support frame 14 connected to the moving shaft 13 to form a linear slide of the telescopic seat 15 under the limit of the seat frame 11. The scissor support frame 14 is controlled to unfold, providing support for the telescopic seat 15. The limit rod 16 assembled with the telescopic seat 15 forms a stable support with the seat frame 11, improving the stability of the telescopic seat 15.

[0057] The movable part 17 is slidably connected to the inner surface of the telescopic seat 15, and the inner surface of the movable part 17 is threadedly connected to a threaded rod 18, and the outer surface end of the threaded rod 18 is nestedly connected to a first bevel gear 19, while the outer surface of the first bevel gear 19 is meshed with a second bevel gear 20.

[0058] Link 21 is rotatably connected to the upper surface of movable part 17, and backrest 22 is rotatably connected to the upper surface of link 21. The lower part of backrest 22 is rotatably assembled on the left side of the outer surface of telescopic seat 15, and seat cushion 23 is attached between backrest 22 and telescopic seat 15.

[0059] The extrusion rod 24 is installed on the right side of the outer surface of the movable part 17, and the outer side of the extrusion rod 24 is rotatably connected to the push rod 25. The other end of the outer surface of the push rod 25 is rotatably connected to the bracket 26. Meanwhile, the right side of the outer surface of the bracket 26 is connected to the support plate 27, and the outer surface of the support plate 27 is equipped with a reinforcing rod 28 and a locking block 29, which are nested and locked into the inner surface of the bracket 26.

[0060] The movable part 17 forms a threaded adjustment limiting sliding structure with the telescopic seat 15 through the threaded rod 18, and the threaded rod 18 forms a meshing structure with the first bevel gear 19 and the second bevel gear 20. The threaded rod 18, the first bevel gear 19 and the second bevel gear 20 are set at equal distances with respect to the inner surface of the telescopic seat 15. At the same time, the movable part 17 forms a positioning rotation structure with the backrest 22 through the connecting rod 21, and the backrest 22 and the telescopic seat 15 are fitted together with the seat cushion 23.

[0061] The extrusion rod 24 and the moving part 17 form an integrated structure, and the extrusion rod 24 and the push rod 25 form a rotating structure, and the push rod 25 and the bracket 26 form a positioning and rotating structure. Meanwhile, the bracket 26 forms a limiting and engaging structure with the support plate 27 through the reinforcing rod 28 and the locking block 29.

[0062] The inner surface of the extrusion rod 24 is rotatably connected to the extrusion roller 2401, and the upper surface of the extrusion rod 24 is equipped with a support rod 2402, which limits the sliding of the support rod 2402 on the inner surface of the telescopic seat 15. The upper surface of the extrusion roller 2401 is attached to the extrusion block 2403, and the upper surface of the extrusion block 2403 is equipped with an inclined plate 2404, which is nested and rotated in the middle section of the inner surface of the telescopic seat 15.

[0063] The extrusion roller 2401 and the extrusion rod 24 form a built-in rotating structure, and the outer surface of the extrusion rod 24 is inclined. The extrusion rod 24, through the extrusion roller 2401 and the support rod 2402, forms a sliding extrusion structure with the extrusion block 2403. At the same time, the extrusion block 2403 and the inclined plate 2404 form an integrated structure, and the lower surface of the extrusion block 2403 is arc-shaped.

[0064] When a rest is needed, the height between the seat frame 11 and the telescopic seat 15 can be lowered, and the motor on the telescopic seat 15 can be started. The output shaft can be controlled to adjust the second bevel gear 20 to mesh with the first bevel gear 19 and rotate. When rotating, it drives the threaded rod 18 assembled by the first bevel gear 19 to rotate. The threaded rod 18 and the moving part 17 can form a threaded limit sliding setting, and the moving part 17 can be controlled to adjust the connecting rod 21 to rotate. The connecting rod 21 adjusts the positioning rotation of the backrest 22 and the telescopic seat 15, controls the angle between the backrest 22 and the telescopic seat 15, and simultaneously adjusts the unfolding angle of the seat cushion 23 assembled between the backrest 22 and the telescopic seat 15.

[0065] While adjusting the angle of the backrest 22, the moving part 17 can be controlled to drive the installed pressing rod 24 to move synchronously. During the movement, the pressing roller 2401 inside the pressing rod 24 can be controlled to support the pressing block 2403, and the assembled support rod 2402 can be controlled to slide in the telescopic seat 15 to provide continuous support for the pressing block 2403. The inclined plate 2404 installed on the pressing block 2403 can be controlled to rotate and position, so that the inclined plate 2404 provides oblique support for the user's buttocks and prevents slippage during use. When adjusting the position of the pressing rod 24, it can rotate with the push rod 25 connected to the pressing rod 24 and the bracket 26 to control the angle of the bracket 26. The bracket 26 can be adjusted by adjusting the angle of the support plate 27 assembled through the reinforcing rod 28 and the locking block 29, which improves the comfort of use and reduces manual adjustment during use, thus controlling the accuracy of angle adjustment.
