Description

Work chair {CHAIR FOR WORK}

The present invention relates to a work chair, and more particularly, to a work chair that can be used by a worker engaged in agriculture or fishery while sitting down and storing belongings of the worker, as well as changing the height according to the height of the worker. it's about

In agricultural or fishing fields, there are many cases of squatting for long periods of time.

Squatting is a very bad posture for the extensor muscles, which are muscles that support the spine from the back and erect the waist, and cause lumbar degenerative kyphosis, in which the spine is abnormally bent forward, or a herniated disc as the disc is pushed backward under excessive pressure. Degenerative changes in the cartilage cause knee pain as the joint is damaged with age. That is, if the squatting posture is maintained, the waist and knees of the worker are adversely affected.

Therefore, in the case of squatting in an agricultural or fishing environment, a work chair is used so as not to burden the waist and knees of the worker.

The work chair is configured with a ring-shaped band on the cushion portion, and after wearing the band by inserting the band on the operator's leg, the cushion portion is placed on the buttocks to be used. That is, as disclosed in Patent Publication No. 10-2020-0030740 (published on March 23, 2020), the work chair is connected with a slide fastener between the upper and lower bodies each consisting of a circular flat part and a band-shaped side part. It consists of a cover, a cushion inserted into the cover, and a waist belt connected to the circumference of the upper body of the cover through sewing, wherein the upper body of the cover is an upper fastener tape with a slide fastener around the circumference of the circular flat plate It can be configured by sewing.

By using the work chair as described above, it is possible to protect the waist and knees by distributing the weight of the operator.

Due to these advantages, the use of a conventional work chair is increasing, and it is used as a necessity in an agricultural or fishing environment.

On the other hand, due to the high penetration rate of portable devices such as smart phones, the number of workers carrying portable devices is increasing even in agricultural or fishery work environments. Accordingly, workers keep belongings such as mobile devices nearby or store them in work clothes.

However, when belongings such as mobile devices are stored in work clothes, there is a problem in that it may cause inconvenience to workers who work by squatting for a long time and may interfere with work. In addition, when belongings such as portable devices are placed near the operator, there is a problem in that the risk of loss or damage increases.

Accordingly, there is a demand for a technology capable of storing the worker's belongings while allowing the worker to sit down when squatting in a working environment such as agriculture or fishery.

The present invention has been proposed to solve the above-described problems, and when a worker has to squat down to work in a poor environment such as agriculture or fishery, the height can be changed according to the height of the worker while the worker can sit down and use it. An object of the present invention is to provide a work chair capable of storing personal belongings.

Another object of the present invention is to provide a work chair capable of preventing slipping on the ground in a working environment.

The problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, a work chair according to the present invention includes a base portion having a storage space and a support 110 standing at the inner center, a seating portion 200 for covering the upper portion of the base portion, In the work chair including a fastening means for fastening the seat portion 200 and the base portion, the support 110 is spaced apart at regular intervals and has a plurality of partition plate fitting grooves formed vertically, and the partition plate fitting grooves are formed. It is fastened to the groove and includes a plurality of partition plates 120 for partitioning the storage space, and the base part includes a first base part 101 and an upper end of the first base part 101 to adjust the height. It includes a second base portion 102 that is laminated and coupled to, wherein the first base portion 101 has a seating protrusion 140 protruding from the upper end and a protruding jaw protruding along the edge of the upper end, The base portion 102 has a seating groove 150 coupled to the seating protrusion 140 when the seating protrusion 140 is inserted into the lower portion to rotate the second base portion 102, and a lower edge of the base portion 102. A step may be formed along the protruding ledge to block external foreign substances from entering the storage space.
In one embodiment, the fastening means is formed on a hinge shaft 400 formed at one end of the base portion 100 and at one end of the seat portion 200 to be rotatable from the hinge shaft 400. A hinge 410 having a shaft groove 411 for inserting the hinge shaft 400, a sealing protrusion 420 protruding from the other end of the base part 100, and the other end of the seating part 200 It may be formed to include a sealing groove member 430 for inserting the sealing protrusion 420.

12 and 13 are fastening means including a hinge and a hinge shaft of a work chair according to another embodiment of the present invention.

In adding quotation marks to the components of the drawings, even if they are displayed on different drawings, only the same components have the same symbols as possible, and known functions that are determined to unnecessarily obscure the subject matter of the present invention. And a detailed description of the configuration is omitted. Also, directional terms such as 'top', 'bottom', 'front', 'back', 'lead', 'front', 'rear', etc. are used in relation to the orientation of the disclosed figure(s). Because components of embodiments of the present invention may be positioned in a variety of orientations, directional terms are used for purposes of illustration and not limitation.

As shown in FIG. 1, the work chair according to an embodiment of the present invention covers a cylindrical base part 100 having a storage space and an open top, and the upper part of the base part 100 while covering It includes a seat portion 200 in which the cushion material 210 is embedded, and fastening means for fastening the seat portion 200 and the base portion 100.

As shown in FIG. 2, the base part 100 may be formed in a cylindrical shape of a synthetic resin material so that the shape is not deformed by a load when a worker is seated, but is not limited thereto, and has a rectangular cylindrical shape, etc. It can be formed in various shapes.

In addition, the base portion 100 has a storage space formed therein so as to store belongings and the like possessed by the operator. Here, the upper part of the base part 100 is opened so that the storage space can be opened.

The storage space formed in the base part 100 can store the worker's belongings, etc., so that the usability can be greatly improved, and the worker's belongings can be prevented from being damaged or lost at the work site, as well as the worker's belongings. Since there is no need to carry a separate bag to store, the convenience of the operator can be improved.

Meanwhile, when a storage space is formed inside the base part 100, the seating part 200 may sink down into the storage space due to a worker's load, but in the present invention, this is prevented and the seating part 200 A support 110 for supporting is configured.
