Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and more specifically, to a nap chair. Background Technology

[0002] In campus life, students have an urgent need for lunch breaks, but existing student lunch break chairs are clearly inadequate. Traditional chairs are mostly fixed in shape, with backrests that cannot be flexibly adjusted to different angles, making it difficult to accommodate students' different lunch break postures, such as hunching over or lying down to relax. The footrest function is missing or inconvenient to adjust, failing to meet the need for leg stretching and affecting the comfort of lunch breaks. In addition, the armrests are mostly fixed structures and cannot be adjusted according to usage scenarios, lacking suitable support when temporarily writing or placing items. At the same time, traditional student chairs are cumbersome to operate when students are temporarily studying or placing items, and lack reasonable storage space, easily causing clutter on the desktop. They cannot provide students with a convenient, comfortable, and practical integrated chair for lunch breaks and study assistance. Therefore, there is still considerable room for improvement in traditional chairs. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5This utility model provides a nap chair, including a seat 100, a backrest 120 rotatably connected to the rear of the seat 100 via a damping pivot 110, a footrest 130 rotatably connected to the front of the seat 100 via a damping pivot 110, and integrated plate-shaped side support plates 140 fixedly installed on both sides of the seat 100. The top of the side support plates 140 is provided with height-adjustable armrests 150, and "H"-shaped support legs 160 are fixedly installed at the bottom of the two side support plates 140. The middle of the two side support plates 140 is hinged to the hinge seat 170 on the inner bottom of the backrest 120 and the inner top of the footrest 130 respectively through the linear transmission module 200. One armrest 150 is rotatably connected to the table 152 at one end through the damping hinge 151, and the other armrest 150 is rotatably connected to the support plate 153 at one end through the damping hinge 151. The front of both side support plates 140 is provided with a storage groove 154 for accommodating the table 152 and the support plate 153.

[0024] Specifically, when students use the nap chair, they can adjust their nap posture by rotating the backrest 120 to adjust the reclining angle and rotating the footrest 130 to stretch their legs, thus meeting their needs for writing homework or napping.

[0025] During the process of students adjusting the angle of the chair back 120 and footrest 130, the lead screw of the linear transmission module 200 moves back and forth and cooperates with the hinge seat 170 to stably transmit the force, so that the hinge seat 170 drives the chair back 120 and footrest 130 to make smooth and stable angle adjustments. The armrest 150 can be raised and lowered to accommodate students of different heights or different scenarios. The table 152 and support plate 153 are connected to the armrest 150 through the damping hinge 151. When studying temporarily, the table 152 can be turned out to place books, and when not in use, it can be stored in the storage slot of the side support plate 154, which better fits the scenario of students alternating between studying and taking a nap.

[0026] In this embodiment: the handrail 150 includes a handrail plate 155, and an electric push rod 156 is fixedly installed at the bottom of the handrail plate 155. The electric push rod 156 is installed in the mounting groove 141 opened at the top of the side support plate 140.

[0027] Specifically, when using the chair, the armrest 150 is used to support the arm when writing. When the armrest is raised or during a nap, it should be kept away from the body. When the armrest is lowered, the electric push rod 156 in the mounting groove 141 receives a control signal and extends or retracts, causing the armrest board 155 to rise or fall along the mounting groove 141, precisely adjusting the height of the armrest 150 to suit different usage scenarios for students. This allows for more flexible arm placement and body extension, avoiding the problem that traditional fixed armrests 150 cannot adapt to diverse needs, and improving comfort during naps and studies.

[0028] In this embodiment: a mounting bracket 142 is fixedly installed on the top outer side of one of the side support plates 140, and a hook 143 for hanging items is fixedly installed on the bottom of the mounting bracket 142.

[0029] Specifically, when students need to temporarily hang small items such as books or water cups during daily use, they can use hooks 143 to hang them. Students can also hang their schoolbags, small cloth bags, etc. on hooks 143. The "H"-shaped support legs 160 provide stable support for the chair. Even if items are hung on the side support 140, it will not affect the overall stability of the lunch break chair. This solves the problems of students' belongings being easily lost and the desktop being cluttered, making the storage of small items more convenient and meeting the needs of campus learning and life.

[0030] In this embodiment: a storage mechanism 157 for placing items is fixedly installed at the bottom of the tabletop 152. A spring pin 1521 is installed at one end of the bottom of the tabletop 152. A socket 1522 is opened at one end of the support plate 153. When the support plate 153 supports the tabletop 152, the pin of the spring pin 1521 is inserted into the socket 1522 to lock the two plates.

[0031] Specifically, when students use the tabletop 152 for studying, the damping hinge 151 rotates both the tabletop 152 and the support plate 153 to a horizontal position, allowing the tabletop 152 to rest on top of the support plate 153. Then, the spring pin 1521 at the bottom of the tabletop 152 pops out and inserts into the insertion hole 1522 of the support plate 153, locking the tabletop 152 and the support plate 153 together to form a wider support surface, thereby ensuring the stability of the tabletop 152 when students use it. When the tabletop 152 is not in use, the spring pin 1521 is pressed to unlock it, and the damping hinge 151 rotates both the tabletop 152 and the support plate 153 to a vertical position and into the storage slot 154, thus storing the tabletop 152 and the support plate 153.

[0032] The storage mechanism 157 at the bottom of the tabletop 152 can hold stationery, small notebooks and other items, making them easy to access and improving the flexibility and practicality of the tabletop 152, making it suitable for campus learning support scenarios.

[0033] In this embodiment: the item storage mechanism 157 is one of an item storage bin or an item storage net.

[0034] Specifically, when the storage mechanism 157 is a storage bin, the rigid or flexible bin-shaped structure can stably support stationery and snacks, making it convenient for students to temporarily access and store them.

[0035] When the storage mechanism 157 is a storage net bag, the flexibility and mesh characteristics of the net bag can quickly store small items, and it is ventilated and does not accumulate dust. The two structural forms of the storage mechanism 157 can better meet the needs of students to store small items when studying or resting on the lunch break chair, solve the problem of traditional tabletop 152 having no storage or inconvenient storage, keep the tabletop 152 area neat and orderly, and adapt to the temporary storage needs of items in the campus scene.

[0036] In this embodiment: the two ends of the lead screw of the linear transmission module 200 are respectively hinged to the hinge seat 170 of the chair back 120 and the footrest 130 by pins. The bottom of the linear transmission module 200 is rotatably connected to the U-shaped seat 210 by pins. The bottom of the U-shaped seat 210 is fixedly installed with the support crossbar 220. The two ends of the support crossbar 220 are respectively fixedly connected to the inner middle of the two side support plates 140.

[0037] Specifically, during the student's adjustment of the backrest 120 and footrest 130 angles, the linear transmission module 200 needs to stably transmit the force. The two ends of the lead screw are hinged to the hinge seats 170 of the backrest 120 and footrest 130 through pins. When rotating for adjustment, the lead screw is connected to the hinge seat 170 through pins, which can flexibly rotate to adapt to the angle change and transmit linear driving force. The U-shaped seat 210 at the bottom of the linear transmission module 200 is rotatably connected by pins, and is fixed to the inner side of the middle of the side support plate 140 at both ends of the support crossbar 220 to form a stable support structure.

[0038] When students operate the damping pivot 110 to adjust 120 and the footrest 130, the linear transmission module 200, together with the U-shaped seat 210 and the support crossbar 220, transmits force to the side support plate 140, making the angle adjustment smooth and the rest chair as a whole stable, meeting the structural stability requirements of students when repeatedly adjusting their posture and ensuring the user experience.

[0039] Example 2

[0040] Please see Figure 6 The technical feature that distinguishes this embodiment from embodiment 1 is that: the interior of one of the side support plates 140 is provided with an installation cavity 144 that communicates with the installation groove 141, and a linear screw module 145 is installed at the bottom of the installation cavity 144. The sliding seat of the linear screw module 145 is fixedly installed with the bottom of the electric push rod 156.

[0041] Specifically, when students need to adjust the position of the handrail 150 to suit different scenarios such as writing and lunch break, the linear screw module 145 in the mounting cavity 144 receives a control signal and starts. Its sliding seat moves horizontally along the screw, driving the electric push rod 156 fixed thereto to move synchronously, thereby enabling the handrail 155 to adjust its position in the horizontal direction. If the height of the handrail 150 needs to be adjusted according to the student's height, the electric push rod 156 can extend and retract based on the horizontal position adjusted by the linear screw module 145, driving the handrail 155 to rise and fall along the mounting groove 141, realizing the dual adjustment function of horizontal displacement and height adjustment.

[0042] For example, when writing, the armrest 150 can be moved closer to the body and adjusted to a suitable height to provide support for the arms. During lunch break, the armrest can be moved further away from the body and lowered to avoid hindering the body's stretching. Compared with the armrest 150, which can only be raised and lowered, the combination adjustment method can better adapt to the precise needs of students with different body shapes and usage scenarios. At the same time, the stable transmission of the linear screw module 145 and the precise extension and retraction of the electric push rod 156 are combined to ensure that the adjustment process is smooth and without jamming. With the support strength of the side support plate 140, the structure can remain stable even with frequent adjustments.

[0043] It should also be noted that the linear screw module 145, electric push rod 156 and linear transmission module 200 can all be controlled by a control switch. The control switch is connected to an external power supply and installed on the top of the handrail plate 155 or the outside of the side support plate 140.
