Description

Technical Field

[0001] The invention relates to the technical field of furniture, in particular to a nap chair. Background Art

[0002] Primary and secondary school students usually take a nap in the classroom, and the bench is used as a nap chair, and the angle of the backrest can be adjusted. At present, the seat plate of the nap chair commonly used in primary and secondary schools is hinged and linked to the backrest. When the backrest tilts backward, the seat plate will slide forward. In addition, according to the actual situation that the height of students of the same age is quite different, the height of the nap chair is set to an adjustable structure, and the supporting legs are usually set to telescopic rods. Based on the scheme of seat back linkage and telescopic rod, the reinforcement beam between the left and right supporting legs cannot be set on the upper part of the telescopic rod (which will affect the height adjustment and increase the difficulty of assembly, and will also easily cause the two supporting legs to be inconsistent and shake), nor can it be set on the top of the telescopic rod (which will make the sliding mechanism under the seat difficult to install). Therefore, the actual product usually sets the beam at the rear end of the supporting component under the seat plate, such as the scheme recorded in Chinese invention patent No. 202321090207.3. The frame of the nap chair is provided with a beam for connecting the support frames on both sides at the connection between the backrest and the seat plate. In the seat state, the beam is covered by the backrest and the seat plate and is not visible. However, when the nap chair is adjusted to the reclining mode, the backrest and the seat will move forward together, resulting in a gap between the crossbeam and the backrest and seat. When adjusting or restoring the backrest, the user's hands are likely to enter the gap area, posing a risk of pinching the hands, affecting the safety of the nap chair, especially considering that the users are all primary and secondary school students with low safety awareness. The safety risks of using such nap chairs cannot be ignored. If a crossbeam is not set at the rear end under the seat, the structural stability of the seat will be lower, and naughty primary and secondary school students may often shake the seat, causing the seat to loosen, resulting in a lower service life of the seat.

[0003] Therefore, the prior art has defects and shortcomings and needs further improvement and development. Summary of the invention

[0043] The present invention provides a nap chair 10 .

[0044] Please refer to Figures 1 to 4 In the first embodiment of the present application, a nap chair 10 is provided. The nap chair 10 includes a seat plate 11, a backrest 12, two L-shaped support beams 13, a first crossbar 133 and a first crossbar 134. Among them, the L-shaped support beam 13 is divided into a first beam section 131 and a second beam section 132, and the seat plate 11 is set on the first beam section 131 by sliding. The sliding connection method can not only provide smooth operation when the seat plate 11 adjusts its angle, but also ensure the relative position stability of the seat plate 11 and the support beam. At the same time, the L-shaped support beam 13 can also provide necessary support for the seat plate 11. The backrest 12 is arranged behind the seat plate 11 and is connected to the seat plate 11 through a hinge structure. The backrest 12 can be tilted toward the front side of the seat plate 11 or restored to an upright state within a certain angle range, so that the nap chair 10 can be converted into a reclining chair form and a seat form at will.

[0045] The prior art nap chairs usually adopt a design in which the seat and the backrest are linked, so that the seat will slide along with it when the backrest is tilted. Due to the linkage design of the seat and the backrest, and the fact that the support legs are height-adjustable using a telescopic rod structure, the crossbeam cannot usually be set at the upper part or top of the telescopic rod. Therefore, the crossbeam is usually set at the rear end of the support component below the seat, that is, the rear end of the first beam section 131 in the present application. However, when the nap chair is adjusted from the seat mode to the reclining mode, the backrest and the seat tilt backwards and move forward at the same time. At this time, a gap area is formed between the crossbeam and the backrest and the seat. In the process of the nap chair returning to the seat mode, the user's hand may accidentally enter the gap area, especially for primary and secondary school students, who are more likely to accidentally put their hands in this position due to their low safety awareness, thereby creating a risk of pinching their hands. Although the setting of the crossbeam in the prior art poses a risk of pinching hands, directly removing the crossbeam will affect the stability of the nap.

[0046] In order to reduce the safety hazard of pinching the hand while ensuring the structural stability of the nap chair 10, the support beam of the nap chair 10 in the present application is an L-shaped support beam 13 composed of a first beam section 131 and a second beam section 132, and the second beam section 132 is located at the rear end of the first beam section 131 and extends upward, a first cross bar 133 is arranged between the two second beam sections 132, and a second cross bar 134 is arranged at the front end of the first beam section 131. The upper end of the second beam section 132 refers to the side of the second beam section 132 away from the first beam section 131; the first cross bar 133 can have a certain distance from the end of the second beam section 132 away from the first beam section 131, and the first cross bar 133 does not have to be arranged at the end of the second beam section 132, as long as the height of the first cross bar 133 is higher than the seat plate 11, and there is no gap between the seat plate 11 and the first cross bar 133 that pinches the hand. The front end of the first beam section 131 refers to the side of the first beam section 131 away from the second beam section 132; the second cross bar 134 can have a certain distance from the end of the first beam section 131 away from the second beam section 132, as long as the position of the second cross bar 134 is located between the support rod 16 and the end of the first beam section 131 away from the second beam section 132 in the horizontal direction.

[0047] It can be understood that the first crossbar 133 is located above the position where the crossbar is set in the prior art. Since there is no crossbar at the rear end of the first beam section 131, there is no gap area formed between the crossbar and the backrest 12 and the seat plate 11 when the nap chair 10 changes from the seat mode to the reclining mode, or returns to the seat mode, which can avoid the risk of hands entering the area and causing pinching. At the same time, the front end of the first beam section 131 is provided with a second crossbar 134, so that the second crossbar 134, the two L-shaped crossbars 13 and the first crossbar 133 together form a stable quadrilateral structure. The second crossbar 134, the two L-shaped crossbars 13 and the first crossbar 133 cooperate with each other, and can play a supporting and fixing role in the structure of the nap chair 10, avoiding the problem of instability of the backrest 12 or shaking of the nap chair 10 due to the imbalance of the supporting structure.

[0048] In summary, the nap chair 10 effectively eliminates the hidden danger of hand pinching while ensuring structural stability, thereby improving overall safety.

[0049] Please refer to Figure 1 and 3 The second cross bar 134 is located below the seat plate 11, and a locking mechanism 15 is provided on the second cross bar 134, which is used to control the deformation of the nap chair 10. The locking mechanism 15 can control the relative positions of the seat plate 11, the backrest 12 and the supporting structure, thereby realizing the conversion and adjustment of the shape of the nap chair 10. The locking mechanism 15 enables the user of the nap chair 10 to easily and quickly adjust the shape of the nap chair 10 to meet different usage requirements.

[0050] See also Figure 3 The locking mechanism 15 includes a limiter 153, a body 152 and a handle 151 which are sequentially connected from the rear side of the seat plate 11 to the front side of the seat plate 11; a through hole 154 is provided on the body 152, and the body is connected to the second cross bar 134 through the through hole 154. Specifically, the limiter 153 is used to limit the deformation of the nap chair 10 to ensure that the nap chair 10 can maintain the seat shape; the body 152 is the main part of the locking mechanism 15, and coordinates the relative movement between the handle 151 and the limiter 153 through the connection with the second cross bar 134; the handle 151 is used for the user to manually operate the locking mechanism 15, so that the shape adjustment of the nap chair 10 is more convenient.

[0051] When the user converts the nap chair 10 from a seat form to a reclining chair form, the user can hold or press the handle 151 with his hand to rotate the handle 151 toward the seat plate 11. At this time, the main body 152 rotates relative to the second cross bar 134, and the main body 152 drives the limiting member 153 to rotate in the direction away from the seat plate 11. The limit of the seat plate 11 is released. At this time, the seat plate 11 is no longer restricted, and the relative angle between the seat plate 11 and the backrest 12 can change.

[0052] The bottom surface of the seat plate 11 is provided with a plurality of ribs 111, and a limiting portion 112 is provided on the plurality of ribs 111. The ribs 111 themselves are a kind of supporting member for strengthening the bottom structure of the seat plate 11. By directly providing the limiting portion 112 on the ribs 111, the limiting portion 112 is supported by the ribs 111, and the limiting portion 112 has a high anti-deformation ability.

[0053] The limiting portion 112 matches the limiting member 153 to play a limiting role. The rib 111 provides a stronger supporting force for the limiting portion 112. The limiting portion 112 on the rib 111 cooperates with the limiting member 153 to form a stable limiting structure.

[0054] Please refer to Figure 3 and Figure 4 The limiting part 112 includes a limiting plate 113, and the limiting plate 113 is staggered with the plurality of ribs 111; specifically, the limiting plate 113 is not parallel to or overlapped with the ribs 111, but is arranged between the ribs 111 in a staggered manner; preferably, the limiting plate 113 is arranged perpendicular to the ribs 111. This staggered layout enables the limiting plate 113 to form a stable support network structure under the seat plate 11, and the ribs 111 provide additional support for the limiting plate 113, thereby further improving the load-bearing capacity and durability of the limiting plate 113.

[0055] The stopper 153 abuts against the stopper plate 113. During the adjustment process of the locking mechanism 15, the stopper 153 can abut against the stopper plate 113 when the seat is restored to the seat form, thereby limiting the change in the relative angle between the seat plate 11 and the backrest 12. Through the abutment relationship between the stopper 153 and the stopper plate 113, the user can stably keep the nap chair 10 in the seat form.

[0056] Please refer to Figure 5 and Figure 6 , a limiting shaft 155 is provided on the side of the limiting member 153 facing the seat plate 11, and the limiting shaft 155 can rotate relative to the limiting member 153; the limiting shaft 155 makes it easier for the limiting member 153 to detach from the limiting portion 112 when the lunch break chair 10 is released from the shape lock. The limiting portion 112 includes a limiting groove 114, which is composed of grooves opened on a plurality of ribs 111. The limiting groove 114 is located on the side of the limiting plate 113 facing the locking mechanism 15, and the limiting shaft 155 matches the limiting groove 114. When the locking mechanism 15 adjusts the angle of the seat plate 11 and the backrest 12, the limiting shaft 155 falls off from the limiting groove 114, or slides into the limiting groove 114.

[0057] See also Figure 5 The locking mechanism 15 further includes a spring 156, which is sleeved on the second crossbar 134, one end of the spring 156 is fixedly connected to the second crossbar 134, and the other end of the spring 156 abuts against the body 152. This structure allows the spring 156 to always be in a certain compressed state, and has the function of providing a return force under certain circumstances.

[0058] See also Figure 7 A first gap 14 is designed between the backrest 12 and the first crossbar 133 to prevent the backrest 12 and the second beam section 132 from pinching fingers when the nap chair 10 is reset from the nap position to the seat position. When the backrest 12 is tilted toward the front of the seat plate 11 or restored to an upright position, there is always a sufficiently large gap between the backrest 12 and the first crossbar 133. This gap can prevent the hand from being pinched even if the hand enters the gap when adjusting the nap chair, thereby significantly reducing the risk of students' hands being pinched.

[0059] Please continue reading Figure 7The backrest 12 includes a back plate 121 and a rib 122. The rib 122 is protrudingly arranged on the side of the back plate 121 away from the seat plate 11. Specifically, the back plate 121 is the main part of the backrest 12, and plays a role in supporting the back of the user. The rib 122 is designed to enhance the stability and supporting force of the back plate 121. The rib 122 is located on the back side of the backrest 12 (i.e., the side away from the seat plate 11). The rib 122 makes the backrest 12 more stable when subjected to force and is not easy to deform. The rib 122 is installed on the side of the back plate 121 away from the seat plate 11 in a protruding manner. The rib 122 can provide additional support for the backrest 12 during the adjustment process of the student chair, while ensuring the stability of the backrest 12 during the adjustment process.

[0060] The rib beam 122 is slidably connected to the first cross bar 133. Specifically, since the rib beam 122 is protruding from the back plate 121 and the first cross bar 133 is slidably connected to the rib beam 122, a first gap 14 between the back plate 121 and the first cross bar 133 is effectively vacated. When a hand is inserted into the first gap 14, there is no risk of pinching the hand, which significantly improves the safety of the nap chair 10.

[0061] A sliding device is provided between the rib beam 122 and the first cross bar 133, so that when the backrest 12 is adjusted, the rib beam 122 can slide smoothly under the guidance of the first cross bar 133. Through this sliding connection, the backrest 12 can remain stable during the adjustment process, avoiding the phenomenon of unsmooth adjustment due to friction or jamming. The sliding connection can be achieved through a slide groove, a slide rail or other sliding devices. The rib beam 122 can be provided with a sliding groove or a slide rail that matches the first cross bar 133, and the first cross bar 133 can be provided with a corresponding sliding component so that the rib beam 122 can slide smoothly during the adjustment process. This design makes the adjustment of the backrest 12 more flexible, and can be smoothly adjusted without affecting the stability of the lunch break chair 10.

[0062] Please continue reading Figure 7Preferably, the present application adopts a simple sliding connection mode in which a strip hole 123 is provided on the rib beam 122 and the first cross bar 133 passes through the strip hole 123. The rib beam 122 is provided with a strip hole 123 extending along the length direction of the rib beam 122; specifically, the strip hole 123 is designed to allow the backrest 12 to make a certain displacement relative to the first cross bar 133 during the adjustment process, so as to achieve the transition between the seat form and the recliner form. The length and width of the strip hole 123 can ensure that the sliding and adjustment process of the backrest 12 relative to the first cross bar 133 is smooth and smooth, and ensure the correct positioning in different states. The first cross bar 133 is fixed to the second beam section 132 and passes through the strip hole 123, which not only allows the backrest 12 to slide freely as needed during the adjustment process, but also ensures that the first cross bar 133 maintains a stable connection between the backrest 12 and the seat plate 11, so that the backrest 12 can move smoothly during the adjustment process, while avoiding the safety hazards caused by unstable connection.

[0063] When the nap chair 10 is in the seat form, the first cross bar 133 is located at one end of the strip hole 123 close to the seat plate 11; when the nap chair 10 is in the reclining form, the first cross bar 133 is located at one end of the strip hole 123 away from the seat plate 11. The strip hole 123 provides displacement space for the backrest 12 relative to the first cross bar 133. By matching the reasonable hole length and hole width, the backrest 12 can be ensured to be smooth and stable when transitioning between the seat and reclining forms.

[0064] Specifically, when the nap chair 10 is converted from a chair form to a reclining chair form, the angle between the backrest 12 and the seat plate 11 increases, the backrest 12 moves forward of the seat plate 11, the center of gravity of the backrest 12 moves downward, and the end of the strip hole 123 away from the seat plate 11 contacts the first cross bar 133, and the first cross bar 133 limits the rib beam 122, restricting the angle between the backrest 12 and the seat plate 11 from continuing to increase, completing the conversion of the reclining chair form. When the nap chair 10 is converted from a reclining chair form to a chair form, the angle between the backrest 12 and the seat plate 11 decreases, the backrest 12 moves backward of the seat plate 11, the center of gravity of the backrest 12 moves upward, and the end of the strip hole 123 close to the seat plate 11 contacts the first cross bar 133, restricting the angle between the backrest 12 and the seat plate 11 from continuing to decrease, and the backrest 12 remains upright or slightly tilted, ensuring that the backrest 12 is in a comfortable and stable chair form.

[0065] Please refer to Figure 1 and Figure 7The area where the backrest 12 is slidably connected to the first crossbar 133 is bent toward the front side of the seat plate 11. The bending setting here can form a reasonable first gap 14 to ensure safety during use, and at the same time, the backrest 12 forms a waist support structure, which is more ergonomic, and leaves enough space for the rib beam 122 to set the strip hole 123, so that the rib beam 123 will not reduce the structural strength due to the opening of the strip hole 122.

[0066] Please refer to Figure 8 and Fig. 9 The width of the lower end of the backrest 12 is smaller than the distance between the two second beam sections 132, so that when the nap chair 10 is in the seat form, a second gap 19 is formed between the backrest 12 and the second beam section 132, so that when the nap chair 10 is in the seat form, the lower end of the backrest 12 will not contact the second beam section 132, so as to prevent the backrest 12 and the second beam section 132 from pinching fingers when the nap chair 10 is reset from the nap form to the seat form.

[0067] See also Fig. 9 A third gap 20 is formed between the seat plate 11 and the second beam section 132 to prevent the seat plate 11 and the second beam section 132 from pinching fingers when the nap chair 10 is reset from the nap form to the chair form. When the nap chair 10 is transformed from the recliner form to the chair form, the gap between the seat plate 11 and the second beam section 132 gradually decreases, which may cause the risk of pinching fingers. The third gap 20 provided in this embodiment can effectively solve this problem. The existence of the third gap 20 prevents the rear end of the seat plate 11 from contacting the second beam section 132 when the nap chair 10 is in the chair form, providing safety protection and avoiding the occurrence of finger pinching accidents. At the same time, the existence of the third gap 20 also reduces the direct contact between the seat plate 11 and the second beam section 132, thereby avoiding the friction and wear that may occur between the two during the adjustment process.

[0068] See also Figure 1 In order to make the nap chair 10 more stable during use, the nap chair 10 is provided with a crossbeam 18. Specifically, the nap chair 10 also includes two support rods 16, two chair legs 17 and a crossbeam 18. One end of the support rod 16 is fixedly connected to the side of the first beam section 131 away from the seat plate 11, and the other end of the support rod 16 is slidably connected to the chair leg 17 and embedded in the chair leg 17. The support rod 16 and the chair leg 17 are designed to be a telescopic structure that can be adjusted in length. The nap chair 10 can adapt to the needs of different heights, so that the nap chair 10 maintains comfort and stability when adjusting between the seat and recliner forms.

[0069] The two chair legs 17 are connected to the first beam section 131 through the support rod 16 to form a stable support structure. The lower part of the chair legs 17 is in contact with the ground to provide support for the overall frame of the lunch break chair 10. The crossbeam 18 is arranged between the two chair legs 17 and is fixedly connected to the chair legs 17. The crossbeam 18 connects the chair legs 17 on the left and right sides, thereby enhancing the lateral stability of the frame of the lunch break chair 10.

[0070] The support rod 16, the chair legs 17, the cross beam 18 and the L-shaped support beam 13 work together to form a solid frame structure. The sliding adjustment design of the support rod 16 and the chair legs allows the height of the lunch break chair 10 to be adjusted. The chair legs 17 provide vertical support, while the cross beam 18 ensures the lateral stability of the entire structure, and the L-shaped support beam 13 supports the seat plate 11. This design ensures that the lunch break chair 10 always remains stable and firm when switching between the seat form and the reclining chair form, meeting the comfort needs of the user.

[0071] In summary, the present invention provides a nap chair, which comprises a seat plate; a backrest, the backrest being arranged at the rear side of the seat plate and being hinged to the seat plate; two L-shaped support beams, the L-shaped support beam being divided into a first beam section and a second beam section, the seat plate being slidably arranged above the two first beam sections, the second beam section being located at the rear end of the first beam section and extending upward; a first cross bar being arranged at the upper end of the two second beam sections, and a second cross bar being arranged at the front end of the two first beam sections; the first cross bar and the second cross bar being respectively connected and fixed to the two L-shaped support beams; the first cross bar being higher than the seat plate, and the backrest being slidably connected to the first cross bar. By arranging the L-shaped support beam and eliminating the cross bar, the hand-clamping gap between the seat plate and the cross bar is effectively eliminated; by arranging the first cross bar and the second cross bar at both ends of the L-shaped support beam, a stable quadrilateral structure is formed together, which reduces the safety hazard of hand-clamping while ensuring the structural stability of the nap chair.

[0072] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
