Description

Portable afternoon nap chair

Technical Field

The invention relates to the technical field of office supplies and furniture manufacturing, and discloses a portable afternoon nap chair.

Background

Due to various reasons, most of staff and students in China can only lie on a desk to sleep during noon break, and a plurality of afternoon nap pillows are added at most.

A plurality of noon break folding beds and folding chairs can well solve the problem of noon break of partial people in a unit and are mainly limited by the problem of placing space, a computer chair is available at present, the sleeping angle of 170 degrees can be adjusted in design, the size of the computer chair can be adjusted, the computer chair is suitable for boss and white collar workers with more spacious office conditions, the computer chair is not suitable for all groups due to some defects, in the prior art, popular types of folding beds can be used for noon break, and the folding noon break chairs which are produced by a fantasy noon break folding bed selling shop on the Taobao and a Mianji sky prosperous on Zhejiang are innovated in design. It has also disadvantages: 1. in a sleeping state, although the chair does not occupy a lot of space, when the chair is used, the four-foot scratcher is too open, the 60X80 cm ground grabbing area is not covered by people, 2, in a narrow office, the sitting, the entering and the exiting of staff are influenced because the chair is not a swivel chair and the armrests cannot be folded, and 3, the chair is just like a deck chair and cannot be used as a stool chair; the latter has higher cost performance, but the defects are as follows: 1. can see 8 feet or 4 wheels of 4 feet during the seat, 2, expose 2 layers of backplate of folding, 3, the front leg because of do not drawing the side not firm enough, do not better move, 4, lie and sleep the function ideal, when the seat very tractive strength, their common illness: the multifunctional bench can be used as a additional bed only in a spacious place, and when the multifunctional bench is used as a bench chair, the volume is not enlarged, or the appearance is not matched with the environment.

A good product needs to be subjected to market investigation, China has a large population and relatively tense resources, schools cannot take out enough rooms and beds to meet the needs of students for afternoon nap, and people cannot cut down the number of students in each class by using your chair for afternoon break, so that the designing of the chair for afternoon break needs to meet some harsh requirements, wherein the conditions comprise: 1. the appearance of the chair is not different from that of the existing common stool chair, 2, the chair is required to be in accordance with human engineering when being changed into lying and sleeping, 3, the chair is required to be adapted to different crowded environments, 4, children can also adopt simple operation modes, 5, ultra-simple manufacturing cost is low, 6, safety, convenience in assembly and transportation and the like are achieved.

At present, people look forward to an apparatus which can meet the requirement of noon break at low cost under the condition of not influencing the overall arrangement and can be based on the existing conditions of companies or schools.

Detailed Description

The foot rest is firmly connected by five transverse pipes 22, the front transverse pipe and the rear transverse pipe are respectively two, one is arranged above the middle, step bolts are arranged at two ends of each transverse pipe 22, locking nuts are matched for screwing, the two ends of the transverse pipe 22 positioned at the upper rear part are connected with L-shaped limiting grooves 11 on the back plate side plates 10 in series, supports 16 are abutted against elastic gaskets 15 at two ends of the front upper transverse pipe, at the moment, a cylindrical pin with a hole at the back of the seat plate frame 1 is clamped into the uppermost end hook of the arc-shaped guide groove, the transverse pipe below the back plate is pushed to limit outward exceeding of the back plate side plates 10, the back plate side plates 10 are limited upwards below the transverse pipe at the upper middle part, the turnover panel 20 which is turned downwards is supported above the horizontal pipe, and the transverse pipe 22 is firmly connected with the foot rest side plates 28 through the locking nuts.

The seat cushion is made of PVC or silicon/rubber, the sleeping cushion is made of NBR or TPE, and the primary school students are in the growth and development period, bones and back columns are not completely developed in place, the children bones are easy to develop and deform due to over-soft sleeping beds, and the children are uncomfortable to lie on the bed when being too hard, so the hardness is selected to be good.

Misoperation prevention: the elastic sheet elastic buckle is arranged on the side plate of the back plate, when the sleeping chair is positioned, the hole on the side plate of the back plate is aligned to the elastic buckle hole on the side plate of the foot rest, when the folding panel is put down, the elastic buckle is pressed to protrude, the positioning is completed, the possibility of randomly lifting the folding panel on the back plate to extrude and damage the seat plate is mainly prevented, and the inclined strip-shaped hole is also arranged on the folding panel, so that the elastic buckle when the back plate is pulled backwards to implement the lengthening sleeping chair is opposite.

The technical problem to be solved by the invention is as follows: according to the technical requirements issued by the national ministry of health and the Chinese standardization research institute, the afternoon nap problem is solved by adjusting and adding a small number of components according to the ergonomics and combining the actual crowdedness of common company staff and school students in reality, the rapid function conversion problem is solved, and the environment matching problem of the product is solved.

The technical scheme is as follows:

1. aiming at congestion: the one-machine two-step type can be completely opened and completely unfolded to sleep on the back and on the left and right sides under the condition that the space allows, such as in a noble school; in crowded office schools, the hand-rest plate is not opened and the foot rest plate is not pulled out in narrow classrooms, the area is reduced by half, and the sleeping method with feet hanging down and lying on the back is not good for hand-rest and is inconvenient for people to lean on, but is quite agreeable for tired people.

2. Environment matching problem: the simple plastic chair is adopted and is tightly matched with the original desk, if a computer chair is taken for class, although the chair is fashionable, the simple plastic chair is attractive and neat and is very suitable for industrial production, the defect is that the height of the chair is not adjustable like a steel tube type, but the chair is a table and chair with fixed grade.

3. The conversion function is as follows: the operation steps and the fixing mode are as follows: sitting and turning to sleep: lifting the lifting belt on the rear part of the seat cushion, pulling out the handle concave 13, lifting the back plate, turning back, and then folding down the turnover panel 20; the sleeping swivel chair: the folding panel 20 is lifted, the backrest plate is lifted to the bottom and then inserted downwards, the seat plate is lifted and then moved to be pressed downwards, the firmness of the seat is realized because the seat plate is clamped in the transverse tube 22 and the stop block 29 below the rear legs after the cylinder 21 on the side plate 10 of the backrest plate is inserted, the L-shaped limiting groove 11 on the seat plate can swing between the transverse tube 22 on the rear upper part at the moment, and the seat plate can be completely stabilized only when the seat plate is pressed downwards.

Briefly: a light afternoon nap chair mainly comprises three parts, namely a foot rest, a seat board and a back board, wherein pin shafts on the left and the right in front of the seat board frame 1 are supported by swing rods 16, a cylindrical column 19 with holes in the back slides along an arc-shaped guide groove 2 to move the seat board forwards and put short, the back board takes an L-shaped limit groove 11 as a center, the seat board can be touched to a transverse pipe 22 above the middle of the foot rest when lifted and turned backwards to the bottom, a downward turning panel 20 is put on the transverse pipe 22, the sleeping state is finished, and otherwise, the operation can be recovered to the state of the chair.
