Description

Technical Field

[0001] This invention belongs to the field of teaching equipment technology, and relates to a desk and chair for lunch break. Background Technology

[0002] Traditionally, students rest by lying face down on their desks during lunch break at school. This affects the quality of their rest, and prolonged face-down rest is also detrimental to students' cervical spine health. Therefore, desks and chairs designed for lunch break have become a trend in the development of existing teaching equipment.

[0003] Existing lunch break desks and chairs typically consist of a desk and a chair. The chair back can be adjusted to recline relative to the seat, allowing the chair to be converted into a reclining position for students to nap. However, due to space limitations in classrooms, the space between desks and chairs in the front and back rows is generally very small, often insufficient to accommodate the reclining position. Therefore, finding a suitable space for students to lie down and sleep within limited space has become a key research focus in the development of existing lunch break desks and chairs.

[0004] For example, Chinese patent application (application number: 202220000333.4) discloses a desk and chair with a plug-in base and easily detachable book drawer. The desk includes two support legs (left and right) and a book drawer and tabletop assembly. The chair includes support legs and a base. The support legs house the seat, and the seat has an adjustable backrest. The book drawer and tabletop assembly are detachably mounted on the two support legs. The detached book drawer and tabletop assembly can be removed from the support legs to free up space above them. In this desk and chair design, removing the book drawer and tabletop assembly from the support legs frees up space above the rear desks for the front seats to recline for naps.

[0005] The desks and chairs have the following drawbacks: During each lunch break, all students in the front and back rows must maintain the same break time. If some students want to continue studying instead of taking a break, the system becomes unsuitable. Furthermore, as is well known, books and other study materials are usually placed on the desks or in the drawers. Each lunch break requires all students to remove these items, disassemble the drawers and tabletops, and then reassemble them after the break, which is cumbersome and inconvenient.

[0006] For convenience during lunch break, the current practice is to install a pull-out box under the chair so that students can put their books and other school supplies in the box. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a new type of desk and chair for lunch breaks. The technical problem to be solved by this invention is: how to solve the problems of poor adaptability and inconvenience in using existing desks and chairs for lunch breaks.

[0008] The objective of this invention can be achieved through the following technical solution: a lunch break desk and chair, comprising a table and a chair. The table includes a tabletop, vertically arranged table support legs, and two parallel table base legs arranged in the front-to-back direction. The chair includes a seat, a backrest, two vertically arranged parallel chair support legs, and two parallel table base legs arranged in the front-to-back direction. The backrest can be adjusted to tilt relative to the seat. The invention is characterized in that only one of the table base legs has the aforementioned table support legs, and the upper end of the table support leg is connected to... On one side of the bottom of the tabletop, the table also includes a lower support crossbar. The two ends of the lower support crossbar are respectively connected to the table support leg and another table base leg. The lower support crossbar, the table support leg, and the two table base legs form a clearance gap that allows one of the chair base legs to pass through. The other side of the tabletop and the lower support crossbar form a clearance notch that allows the seat to pass through. A crossbar is connected between the two chair base legs. The crossbar is located near the rear end of the chair base legs, and the crossbar and the two chair base legs form a clearance space that allows the table base leg without a table support leg to extend into.

[0009] The desks and chairs for this lunch break class have a support leg on only one of the table's legs, creating a single-sided support structure. This results in a gap between the lower support crossbar and the other side of the tabletop, freeing up space on one side of the table. Furthermore, the lower support crossbar doesn't connect between the two table legs as usual; instead, one end connects to the support leg, and the other end connects to the upper part of the other table leg, creating an arched or U-shaped gap. Combined with the crossbar between the two chair legs located at the rear of the chair legs, creating a clearance space, this allows the chair to be moved back and forth to be inserted during lunch breaks by offsetting it with the table, and it can also be pulled out laterally through the gap. For example, taking a table with legs on the left as an example, during lunch break, students can offset the chair legs from the table legs, inserting the chair under the tabletop so that the inner wall of the right chair leg is against the outer wall of the right table leg, while the left chair leg passes through the clearance gap, and the right table leg extends into the clearance space. The chair seat passes through the clearance gap, allowing the right chair leg to slightly utilize the aisle space or the gap between two rows of desks and chairs, thus moving the chair forward and creating space for the backrest to recline, forming a reclining chair for lunch break. Alternatively, when the aisle space is large, students can offset the chair legs from the table legs, moving the chair forward under the table so that the inner wall of the left chair leg is against the inner wall of the right table leg, and the left chair leg passes through the clearance gap. The chair can be moved forward and pulled out from under the table by passing through the clearance gap, creating space for the backrest to recline and utilize the aisle space to form a reclining chair for lunch break. Alternatively, when the aisle space is small, students near the aisle can offset the chair legs from the table legs and tilt the chair at a certain angle, moving it forward under the table. The left chair leg passes through the clearance gap, partially moving the chair under the table and extending it out of the aisle. The side table leg extends into the clearance space, and the chair seat passes through the clearance gap, creating space for the backrest to recline and utilizing a small portion of the aisle space to form a reclining chair for lunch break. This lunch break desk and chair arrangement eliminates the need for students in front and behind to coordinate during lunch break, allowing students to choose whether or not to rest, making it highly adaptable. Furthermore, only slight adjustments to the chair position are needed during lunch break; there is no need to disassemble the tabletop, making it convenient to use. Meanwhile, the lower support rod is connected to the table support leg at one end via an unconventional method, and to the upper part of another table base leg at the other end. This effectively forms an arched or U-shaped support frame under the table, which can distribute the stress concentration on one side of the support, improve the strength of the support, and prevent the table from tipping over due to unilateral force during normal use. Moreover, when used as a normal school desk and chair, the absence of a table support leg on one side makes it easier for students to get in and out of their seats, and also allows for better leg extension during normal use.

[0010] In the aforementioned lunch break desks and chairs, the lower support crossbar is L-shaped, with the long side fixed to the side of the desk support leg and the short side fixed to the upper part of another desk base leg. This L-shaped design creates an arched or U-shaped clearance, allowing the chair leg to pass through. It also disperses stress concentration on one side of the support, increasing its strength and preventing the desk from tipping over due to unilateral stress during normal use. Furthermore, the short side of the lower support crossbar being fixed to the upper part of the desk base leg ensures a clearance while maintaining a relatively low height relative to the ground, functioning as a footrest without restricting student leg movement.

[0011] In the aforementioned lunch break desks and chairs, the table also includes at least two upper support crossbars. The bottom of the tabletop has a drawer, and the upper ends of the table support legs are connected to one side of the tabletop's bottom surface. The upper support crossbars are L-shaped, with one end connected to the table support leg and the other end connected to the other side of the tabletop's bottom surface. A U-shaped space is formed between the upper support crossbars and the table support leg, and the drawer is embedded in this U-shaped space. By setting up the upper support crossbars and connecting them to the other side of the tabletop, the force on the entire tabletop can be evenly distributed, preventing breakage at the connection between the tabletop and the table support leg due to unilateral force. Furthermore, combined with the structure of the lower balancing crossbars, the overall support strength can be consistent with that of the two side supports. Simultaneously, since the drawer is generally made of materials such as sheet metal, which are relatively weak, the L-shaped support crossbars allow their connection to the tabletop to avoid the drawer, preventing deformation under stress.

[0012] In the aforementioned lunch break desks and chairs, the table support legs are fixed to the middle of the table base legs. The tabletop is secured to the table support legs, and also to the upper support crossbar, using fasteners. The table support legs are fixed to the middle of the table base legs, resulting in a symmetrical distribution of the entire table leg assembly. This ensures that the table legs are universally compatible with both left-side and right-side supported tables during manufacturing, and also improves the overall uniformity of stress distribution.

[0013] Preferably, in the above-mentioned lunch break desks and chairs, the bottom sides of the tabletop are fixed with L-shaped connecting plates, the upper end of the table support leg and one end of the upper support crossbar are respectively provided with connecting flange one and connecting flange two, the connecting flange one and connecting flange two are respectively attached to the corresponding connecting plates and fixed by fasteners.

[0014] In the aforementioned lunch break desks and chairs, the desk support legs include a T-shaped connecting frame and two height-adjustable telescopic tubes. The two telescopic tubes are arranged parallel to each other, with their lower ends fixed to the same desk base and their upper ends fixed to one side of the desk surface. The two telescopic tubes are connected as a single unit by the connecting frame, the lower end of which is fixed to the desk base. One end of the lower support crossbar is connected to the connecting frame. The design of the two telescopic tubes in the desk support legs prevents the desk surface from wobbling due to the gaps in the telescopic tubes' extension and retraction. Furthermore, the T-shaped connecting frame structure allows the two telescopic tubes to form a frame-like reinforcing structure when connected to the desk base, another frame-like reinforcing structure when connected to the desk surface, and yet another frame-like reinforcing structure when placed on the ground and connected to the lower support crossbar. This ensures overall support strength and prevents tipping or breakage due to unilateral stress.

[0015] In the aforementioned lunch break desks and chairs, there are two upper support crossbars, each connected to a telescopic tube. The outer diameter of the upper support crossbar closer to the front of the desk is larger than that of the upper support crossbar closer to the rear of the desk. When the chair back is adjusted to a reclining position for napping, the body is tilted downwards. This design effectively saves space under the rear of the desk (the side closest to the user during use).

[0016] As an alternative, in the aforementioned lunch break desks and chairs, the table support legs are height-adjustable telescopic tubes, and there are two upper support crossbars forming an angle between them. The connection points of the two upper support crossbars to the tabletop are located near the front and rear sides of the tabletop, respectively. By setting the upper support crossbars and connecting them to the other side of the tabletop, the force on the entire tabletop can be evenly distributed, preventing breakage at the connection point between the tabletop and the table support legs due to unilateral stress. Furthermore, combined with the structure of the lower balancing crossbar, the overall support strength can be consistent with that of the two side supports. Simultaneously, since the table drawer is generally made of materials such as sheet metal, which are relatively weak, the L-shaped support crossbar allows its connection to the tabletop to avoid the drawer, preventing deformation under stress.

[0017] Compared with existing technologies, the desks and chairs for lunch breaks have the following advantages:

[0018] 1. Chairs and desks can be inserted in the front and back directions and pulled out from the gaps in the left and right directions. During lunch break, students in the front and back rows do not need to cooperate. Students can choose whether or not to take a lunch break according to their own needs, making it highly applicable.

[0019] 2. During lunch break, you only need to move the chair slightly. There is no need to remove the books or other study materials on the table or disassemble the tabletop, making it very convenient to use.

[0020] 3. It is more convenient for students to enter and exit their seats, and it is also easier for students to stretch their legs normally. At the same time, the overall support performance and strength are good, and there will be no side tipping or breakage due to unilateral force. Attached Figure Description

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] Example 1

[0029] like Figure 1-5 As shown, the lunch break desk and chair set includes a table 1 and a chair 2. The table 1 includes a tabletop 1a, a lower support crossbar 1d, vertically arranged table support legs 1b, two parallel table base legs 1c arranged in the front-to-back direction, and at least two upper support crossbars 1g. The chair 2 includes a seat 2a, a backrest 2b, two parallel vertically arranged chair support legs 2d, and two parallel table base legs 2c arranged in the front-to-back direction.

[0030] Specifically, the two chair support legs 2d connect the seat plate 2a and the two chair base legs 2c, and the backrest 2b can be adjusted to tilt relative to the seat plate 2a. In this embodiment, the chair 2 also includes an extension plate 2g, which is movably connected to the seat plate 2a. The extension plate 2g can be used as a reclining board, and when not in use, it can be folded down or extended under the seat plate 2a. Of course, the chair 2 may not have an extension plate 2g, and it can be selected according to actual needs. A crossbar 2e connects the two chair base legs 2c. The crossbar 2e is located near the rear end of the chair base legs 2c, and a clearance space 2f is formed between the crossbar 2e and the two chair base legs 2c, allowing the table base leg 1c without the table support leg 1b to extend into.

[0031] Only one of the table legs 1c is provided with a table support leg 1b. The upper end of the table support leg 1b is connected to the bottom of one side of the tabletop 1a. The two ends of the lower support crossbar 1d are respectively connected to the table support leg 1b and the other table leg 1c. A clearance gap 1e is formed between the lower support crossbar 1d, the table support leg 1b, and the two table legs 1c, allowing one of the chair legs 2c to pass through. A clearance gap 1f is formed between the other side of the tabletop 1a and the lower support crossbar 1d, allowing the seat plate 2a to pass through.

[0032] Furthermore, the table support leg 1b is fixed to the middle of the table base leg 1c, so that the entire table leg is symmetrically distributed front and back, thus making the table legs universally compatible when manufacturing this class desk and chair, whether it is a table 1 supported on the left or a table 1 supported on the right.

[0033] Furthermore, the table support leg 1b includes a T-shaped connecting frame 1b3 and two height-adjustable telescopic tubes 1b2. The two telescopic tubes 1b2 are arranged in parallel, and their lower ends are fixed to the same table base leg 1c. The two telescopic tubes 1b2 are connected as one unit by the connecting frame 1b3, the lower end of which is fixed to the table base leg 1c. The lower support crossbar 1d is L-shaped, with its long side fixed to the side of the connecting frame 1b3 and its short side fixed to the upper part of the other table base leg 1c, thus forming an arched or U-shaped clearance gap 1e. In this embodiment, the length of the short side of the lower support crossbar 1d is 5–15 cm.

[0034] The bottom of the tabletop 1a has a drawer 1h. L-shaped connecting plates 3 are fixed to both sides of the bottom of the tabletop 1a. The two connecting plates 3 are positioned on the left and right sides of the drawer 1h and are designed to be close to the drawer 1h. The upper end of the drawer 1h also has mounting edges that fold to the left and right sides respectively. Both connecting plates 3 are fixed to the tabletop 1a with fasteners, and the mounting edges are clamped between the connecting plates 3 and the tabletop 1a. The upper ends of the two telescopic tubes 1b2 have connecting flanges 1b1, which are close to the corresponding connecting plates 3 and fixed with fasteners. There are two upper support crossbars 1g, both of which are L-shaped. The long sides of the two upper support crossbars 1g are located on the upper side of the two telescopic tubes 1b2, and the long sides of the two upper support crossbars 1g are located below the table drawer 1h. The short side of the upper support crossbar 1g has a connecting flange 2 1g1, which is abutted against the corresponding connecting plate 3 and fixed by fasteners. A U-shaped space is formed between the upper support crossbar 1g and the table support leg 1b, and the table drawer 1h is embedded in the U-shaped space. The outer diameter of the upper support crossbar 1g near the front of the tabletop 1a is larger than the outer diameter of the upper support crossbar 1g near the rear of the tabletop 1a, which can better save the space under the rear of the table 1 (i.e., the side closer to the user when in use).

[0035] When using these desks and chairs for lunch break, taking table 1 with table support leg 1b on the left as an example, during lunch break, students can offset chair legs 2c from table legs 1c, insert chair 2 under tabletop 1a, so that the inner wall of right chair leg 2c is against the outer wall of right table leg 1c, left chair leg 2c passes through clearance 1e, right table leg 1c extends into clearance space 2f, and chair seat 2a passes through clearance gap 1f. This allows the right chair leg to slightly utilize the aisle space or the gap between two rows of desks and chairs, thus allowing chair 2 to move forward, creating space for the backrest 2b to tilt backward, forming a reclining chair for lunch break (e.g., Figure 3 (As shown); or when the aisle space is large, students can offset the chair legs 2c from the table legs 1c, move the chair 2 forward to under the table 1, so that the inner wall of the left chair leg 2c is against the inner wall of the right table leg 1c, the left chair leg 2c passes through the clearance 1e, the right table leg 1c extends into the clearance space 2f, and the seat 2a of the chair 2 passes through the clearance gap 1f, thus allowing the chair 2 to move forward and be pulled out laterally from under the table 1, creating space in front and behind for the backrest 2b to tilt backward, while using the aisle space to form a nap recliner (as shown); Figure 1(as shown); or, when the aisle spacing is small, students next to the aisle can offset the chair legs 2c from the table legs 1c and tilt the chair 2 at a certain angle, moving the chair 2 forward under the table 1. The left chair leg 2c passes through the clearance gap 1e, partially moving the chair 2 under the table 1 and extending it out of the aisle. The side table leg 1c extends into the clearance space 2f, and the chair 2 seat 2a passes through the clearance gap 1f, thus creating space in front and behind for the backrest 2b to tilt backward. At the same time, it utilizes a small portion of the aisle space to form a reclining chair for lunch break (as shown). Figure 2 (As shown). Using these lunch break desks and chairs eliminates the need for students in the front and back rows to coordinate during lunch breaks. Students can choose whether or not to take a break based on their own needs, making it highly adaptable. Furthermore, during lunch breaks, only the position of chair 2 needs to be slightly moved; there's no need to disassemble the tabletop 1a, making it quite convenient to use.

[0036] The table 1 of this lunch break desk and chair features a single-sided support structure, creating a clearance gap 1f between the tabletop 1a and the lower support crossbar 1d on the other side. When used as a normal desk and chair, the absence of a table support leg 1b on one side makes it easier for students to get in and out of their seats and allows for greater leg extension. Furthermore, the two telescopic tubes 1b2 are connected by a T-shaped connecting frame 1b3, forming a frame-like reinforcement structure when connected to the table base leg 1c, another frame-like reinforcement structure when connected to the tabletop 1a, and yet another frame-like reinforcement structure when placed on the ground when connected to the lower support crossbar 1d. Combined with the support and stress distribution provided by the two upper support rods, this ensures overall structural strength and prevents tipping or breakage due to unilateral stress.

[0037] Example 2

[0038] The structure and principle of the lunch break desk and chair in this embodiment are basically similar to those in Embodiment 1. The difference is that the table support leg 1b is a height-adjustable telescopic tube 1b2, and there are two upper support crossbars 1g. The two upper support crossbars 1g form an angle between them, and the connection points of the two upper support crossbars 1g and the tabletop 1a are respectively located near the front and rear sides of the tabletop 1a. The support points of the two upper support bars and the tabletop 1a, as well as the support points of the table support leg 1b and the tabletop 1a, are located on the left and right sides of the tabletop 1a, respectively, and are distributed in a three-point manner. This allows the force on the entire tabletop 1a to be evenly distributed, avoiding breakage at the connection point between the tabletop 1a and the table support leg 1b due to unilateral force.

[0039] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0040] Although this document frequently uses terms such as table 1, tabletop 1a, table support leg 1b, connecting flange one 1b1, telescopic tube 1b2, connecting frame 1b3, table base leg 1c, lower support crossbar 1d, clearance spacing 1e, clearance notch 1f, upper support crossbar 1g, connecting flange two 1g1, table drawer 1h, chair 2, seat 2a, backrest 2b, chair base leg 2c, chair support leg 2d, crossbar 2e, clearance space 2f, extension plate 2g, and connecting plate 3, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
