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 seat. When the backrest is adjusted or restored, 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 this type of nap chair cannot be ignored.

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

[0004] The main purpose of the present invention is to provide a nap chair, aiming to solve the potential safety hazard of easily pinching hands when adjusting the existing nap chair.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a nap chair, which comprises:

[0014] When the nap chair is in the form of a reclining chair, the cross bar is located at an end of the strip hole away from the seat plate.

[0015] Preferably, the inner wall of the strip-shaped hole is arranged to be arc-shaped, and the width of the strip-shaped hole first decreases and then increases in the width direction of the rib beam.

[0016] Preferably, the width of the end of the strip-shaped hole close to the seat plate and the width of the end of the strip-shaped hole away from the seat plate are both smaller than the width of the cross bar.

[0017] Preferably, a first gap is provided between the backrest and the cross bar to prevent fingers from being pinched by the backrest and the second beam section when the nap chair is reset from the nap form to the seat form.

[0018] Preferably, the width of the lower end of the backrest is smaller than the distance between the two second beam sections, so that when the nap chair is in the seat form, a second gap is formed between the backrest and the second beam sections to prevent the backrest and the second beam sections from pinching fingers when the nap chair is reset from the nap form to the seat form.

[0019] Preferably, when the nap chair is in a chair form, a third gap is formed between the seat plate and the second beam section to prevent fingers from being pinched by the seat plate and the second beam section when the nap chair is reset from the nap form to the chair form.

[0039] The present invention provides a nap chair 10 .

[0040] Please refer to Figure 1 to Figure 2 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 and a cross bar 133. 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.

[0041] 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 supporting legs adopt a telescopic rod structure for height adjustment, the crossbeam cannot usually be set on the upper part or top of the telescopic rod. Therefore, the crossbeam is usually set at the rear end of the supporting 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 chair 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 chair mode, the user's hand may accidentally enter the gap area, especially for primary and secondary school students. Due to their low safety awareness, they are more likely to accidentally put their hands in this position, thereby creating the risk of pinching their hands.

[0042] In order to improve safety, the support beam of the lunch break 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, and a crossbar 133 is arranged between the two second beam sections 132, and the crossbar 133 is located at the upper ends of the two second beam sections 132. 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 crossbar 133 can have a certain distance from the end of the second beam section 132 away from the first beam section 131, and the crossbar 133 does not have to be arranged at the end of the second beam section 132, as long as the height of the crossbar 133 is higher than the seat plate 11, and there is no gap between the seat plate 11 and the crossbar 133 that can pinch the hand. It can be understood that by setting the L-shaped support beam 13, the crossbar 133 is arranged on the second beam section 132, so that the crossbar 133 is located above the position where the crossbar is arranged in the prior art. Since there is no cross beam at the rear end of the first beam section 131, there is no gap area between the cross beam 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, thereby avoiding the risk of pinching the hand when the hand enters the area.

[0043] In summary, the nap chair 10 effectively eliminates the hidden danger of pinching hands and improves overall safety. In particular, considering that the user group of the nap chair 10 of the present application is primary and secondary school students, this design significantly reduces the safety hazards of existing nap chairs used by primary and secondary school students, thereby improving comfort and safety during use.

[0044] A first gap 14 is designed between the backrest 12 and the 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 crossbar 133. This gap can prevent the hand from being pinched even if the hand enters the gap when the nap chair is adjusted, thereby significantly reducing the risk of students' hands being pinched.

[0045] It is particularly important to point out that the crossbar 133 not only effectively reduces the risk of pinching the hand by setting the first gap 14 between the backrest 12 and the crossbar 133, but also the crossbar 133 and the L-shaped support beam 13 can play a supporting and fixing role in the structure of the nap chair 10. The crossbar 133 and the second beam section 132 jointly bear the force of the backrest 12 during adjustment and normal use, avoiding the problem of instability of the backrest 12 or shaking of the nap chair 10 due to the imbalance of the support structure.

[0046] See also Figure 2 The 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. Preferably, 1-2 ribs 122 can be provided. The ribs 122 are designed to enhance the stability and supporting force of the back plate 121. The ribs 122 are located on the back side of the backrest 12 (i.e., the side away from the seat plate 11). The ribs 122 make the backrest 12 more stable when subjected to force and not prone to deformation. The ribs 122 are installed on the side of the back plate 121 away from the seat plate 11 by a protruding arrangement. The ribs 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.

[0047] The rib beam 122 is slidably connected to the cross bar 133. Specifically, since the rib beam 122 is protruding from the back plate 121 and the cross bar 133 is slidably connected to the rib beam 122, the first gap 14 between the back plate 121 and the cross bar 133 is effectively vacated. When the hand is inserted into the first gap 14, there is no risk of pinching the hand, which significantly improves the safety of the lunch break chair 10.

[0048] A sliding device is provided between the rib beam 122 and the cross bar 133, so that when the backrest 12 is adjusted, the rib beam 122 can slide smoothly under the guidance of the 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 cross bar 133, and the 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.

[0049] Please refer to Figure 2 and Figure 3 Preferably, the present application adopts a simple sliding connection method in which a strip hole 123 is provided on the rib beam 122 and a 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 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 cross bar 133 is smooth and smooth, and ensure the correct positioning in different states. The 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 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.

[0050] When the nap chair 10 is in the seat form, the 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 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 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.

[0051] 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 cross bar 133, and the 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 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.

[0052] See also Figure 3 , the width of the end of the strip hole 123 close to the seat plate 11 and the width of the end of the strip hole 123 away from the seat plate 11 are both smaller than the width of the middle area of ​​the strip hole 123. The purpose is to ensure that during the adjustment process of the backrest 12, the width of the middle part of the strip hole 123 is greater than the diameter of the cross bar 133, thereby reducing the contact area between the middle part of the strip hole 123 and the cross bar 133, reducing friction, and making the deformation smoother. When the cross bar 133 slides to the middle part of the strip hole 123, the width of the middle part of the strip hole 123 is sufficient to accommodate the cross bar 133 to ensure its smooth passage; and when the deformation is completed, the width of the end of the strip hole 123 gradually decreases to be smaller than the width of the cross bar 133, so that the cross bar 133 can be gradually and stably clamped, thereby fixing the position of the deformed backrest 12, avoiding the cross bar 133 directly hitting the end of the strip hole 123 to make a loud noise, and also making the lunch break chair 10 less likely to shake after deformation and more stable. It should be noted that those skilled in the art can understand that the widths of both ends of the strip-shaped hole 123 only need to be slightly smaller than the width of the cross bar 133 to avoid problems of getting stuck or being difficult to disengage.

[0053] See also Figure 4 The inner wall of the strip hole 123 is set to be arc-shaped, so that the width of the strip hole 123 first decreases and then increases in the width direction of the rib beam 122, thereby effectively reducing the contact area between the cross bar 133 and the inner wall of the strip hole 123, thereby reducing the generation of friction, ensuring that the adjustment process of the backrest 12 is smoother, and making the lunch break chair 10 smoother during the deformation process.

[0054] Please refer to Figure 1 to Figure 2The area where the backrest 12 is slidably connected to the 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.

[0055] Please refer to Figure 6 and Figure 7 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 restored from the nap form to the seat form. Due to the second gap 19 between the backrest 12 and the second beam section 132, when the nap chair 10 is restored from the reclining chair form to the seat form, there is a larger space for movement between the backrest 12 and the second beam section 132, and it is not easy to pinch your hands, thereby reducing the risk of pinching your hands.

[0056] See also Figure 7 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 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.

[0057] See also Figure 5 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.

[0058] 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.

[0059] 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.

[0060] In summary, the present invention provides a nap chair, which includes a seat plate; a backrest, the backrest is arranged on the rear side of the seat plate and is hinged to the seat plate; two L-shaped support beams, the L-shaped support beam is divided into a first beam section and a second beam section, the seat plate is slidably arranged above the two first beam sections, the second beam section is located at the rear end of the first beam section and extends upward; a cross bar is arranged at the upper end of the two second beam sections; the cross bar connects and fixes the two L-shaped support beams; the cross bar is higher than the seat plate, and the backrest is slidably connected to the cross bar. By providing an L-shaped support beam, eliminating the cross beam, and providing a cross bar above the seat plate to fix the two L-shaped support beams, the hand-pinching gap between the seat plate and the cross beam is effectively eliminated, ensuring that the user's hands will not enter the dangerous area when switching between the seat and recliner forms, thereby significantly reducing the risk of hand pinching.
