Republic of Korea Utility Model Registration No. 20-0293607 "Left-Handed Lecture Book Holder"

Korea Utility Model Registration No. 20-0334199 "Training Chair"

The present invention relates to a lecture desk chair of the present invention, and more particularly, to a right-handed and left-handed desk chair for anyone to sit and write easily regardless of right-handed or left-handed.

The term " desktop " above and below does not mean a desk or a stool, and an object having an upper plate of the desk integrally with a chair is referred to as a stool.

Generally, desks and chairs are separated from each other in an academy or a school. However, due to the convenience of use and ease of transportation, a desk table with an integrated upper plate is often used in a university classroom.

In general, a bookshelf has an armrest formed on the right side of the bookshelf in consideration of a right handed person. However, if the left-handed person is sitting on a bookshelf considering this right-handed person, he feels a lot of inconvenience when writing.

Korean Utility Model Registration No. 20-0293607 "Left-Handed Lecture Book Holder" as a conventional technology integrated in the present specification was proposed by the present applicant, and the armrest was formed on the left side of the bookshelf in consideration of the left hand.

This conventional technique is a friendly technique in that it considers left-handedness, but the number of left-handed bookcases that can be placed throughout the classroom is limited, and there is a problem that left-handed people have to deliberately find a left-handed desk. Accordingly, when the right-handed person sits on the left-handed person, there is a problem that the right-handed person feels uncomfortable.

Korean Utility Model Registration No. 20-0334199 as a conventional technology integrated in the present specification provides a desk support, that is, a rotating shaft capable of rotating a top plate on a frame, and the frame on the left or right side of the chair. By selectively binding, the top plate was rotated so that the bookcase could be used for right-handed or left-handed use as needed.

However, the prior art is very difficult to selectively combine the frame to the left or right side of the chair itself (it can not be seen that the weight of the top plate is very light), and also to the site where the top plate is not stably supported and selectively joined There is a problem of being structurally very unstable by being supported.

The present invention has been made in view of the problems of the prior art as described above, it is intended to propose a right-handed and left-handed desk chair that anyone who can right-handed or left-handed can sit comfortably on the desk.

In addition, such a right-handed and left-handed bookshelf must have a structurally stable structure, and can be easily converted from right-handed to left-handed use or from left-handed to right-handed.

In order to solve the above problems, the present invention, the top plate is integrally provided on the chair, the top plate is: a central top plate located in the center and fixed to the chair; A side upper plate having an armrest portion formed to be rotatable with a central portion of the central upper plate as a rotation axis and positioned on a left or right side of the central upper plate; Characterized in that divided into.

In the above, it is preferable that the width L1 of the center top plate is longer than the width L2 of the side top plate.

In the above, it is preferable that a guide tuck for limiting the rotation of the side upper plate is provided on the bottom of the central upper plate.

In the above, it is preferable that a fixing device for maintaining the state where the side top plate and the central top plate are located on one plane is added.

Hereinafter, the configuration and operation of the first embodiment according to the present invention will be described in detail.

FIG. 1 is a view illustrating a change state of a book stand as a first embodiment according to the present invention, FIG. 2 is an enlarged view of a change state of a top plate portion in FIG. 1, and FIG. 3 is a rear view of the top plate of FIG. 1. 4 is a cross-sectional view illustrating the structure of the fixing device of FIG. 1.

The bookshelf as shown is composed of a chair 10 and the top plate 100 is provided integrally with the chair (10). The structure in which the top plate 100 itself is provided integrally with the chair 10 is known in a wide variety of structures, the present embodiment is only one example.

The upper plate 100 is divided into a central upper plate 110 and a side upper plate 120.

The central top plate 110 is a part which is fixed to the chair 10 and does not move.

The side upper plate 120 is formed with an armrest portion 121, the armrest portion 121 becomes a portion supporting the arm when writing.

The side upper plate 120 is provided to be rotatable with the central portion of the central upper plate 110 as the rotation axis. In this embodiment, the rotating bar 122 is rotatably provided at the upper and lower portions of the central portion of the central upper plate 110, and the other end of the rotating bar 122 is fixed to the side upper plate 120. . As such, the structure in which the side top plate 120 is rotatable with respect to the center top plate 110 may be proposed in various configurations.

Therefore, as shown in FIGS. 1 and 2, when the user grabs and turns the side top plate 120, the side top plate 120 is located at the left or right side of the center top plate 110.

On the other hand, the guide plate 130 is fixedly provided on the bottom of the central top plate 110, the guide plate 130 has a portion protruding to the side of the central top plate 110, the protruding portion is the side top plate 120 It serves as a guide jaw 131 for limiting the rotation of.

That is, when the side top plate 120 is in a state forming a plane with the central top plate 110, the side top plate 120 is no longer able to rotate downward by the guide jaw 131. Of course, according to the embodiment, the guide jaw 131 may be formed on the upper surface of the side upper plate 120, but such a configuration is not preferable because the protrusion is formed on the upper plate 110.

In addition, the bookshelf is provided with a fixing device for selectively fixing the position of the side top plate (120). That is, the fixing device functions to prevent the side top plate 120 from moving without special manipulation once the side top plate 120 is in a state of forming one plane with the central top plate 110.

To this end, two fixing grooves 111 are formed on the side of the central upper plate 110, and a fixing pin 122a is provided on the rotation bar 122.

As shown in FIG. 4, the fixing pin 122a is supported by the spring 122b. The fixing pin 122a protrudes toward the fixing groove 111, and the user moves the side upper plate 120. In order to rotate, pulling the fixing pin 122a to the outside, the fixing structure is released to enable the rotation of the side upper plate 120, and the rotation of the side upper plate 120 is completed and the fixing pin 122a is completed. When the fixing pin 122a is advanced to the fixing groove 111 by the elastic force of the spring 122b is coupled to the fixing groove 111.

The structure of such a fixing device is not limited to this embodiment, various structures can be proposed.

Also, as shown in FIG. 2, the width L1 of the central upper plate 110 is preferably longer than the width L2 of the side upper plate 120. This is necessary to make the width of the upper plate 100 longer.

The overall width of the top plate 100 may be represented by (L1 / 2 + L1 / 2 + L2) in consideration of the center point of the center top plate 110, and (L1 / 2 + L2) has a certain limit.

Therefore, in order to lengthen the width of the top plate 100, the length of L1 / 2 must be long, and therefore, a practically usable bookcase should have a width L1 of the center top plate 110 longer than the width L2 of the side top plate 120.

Meanwhile, in some embodiments, the width L2 of the side upper plate 120 may be zero. That is, only the armrest part 121 is formed on the side upper plate 120, and the armrest part 121 may be provided to be rotatable with respect to the central upper plate 110. In practice, however, this structure can impair the structural stability of the top plate. In order to achieve a stable top plate structure, the width L2 of the side top plate 120 is preferably at least 1 cm or more.

5 to 6 are photographs of another embodiment according to the present invention.

Although the shape of the side top plate 120 and the like in the above embodiments are slightly different, it can be seen that the same as the first embodiment in terms of basic principles.

On the other hand, the above embodiments have been described under the premise of making a completely new bookshelf, but according to the embodiment, if the top plate structure of the conventional right-handed bookshelf is adapted by applying the concept of the present invention, both right-handed and left-handed combined are very easy. I can make a desk. Particularly, the embodiment of FIG. 6 is an example in which the right-handed bookshelf is modified.

The above embodiments are merely preferred embodiments of the present invention, and the technical idea of the present invention may be variously modified or adjusted by those skilled in the art. Such modifications and adjustments fall within the scope of the present invention if they use the technical idea of the present invention.

As described above, the present invention provides a right-handed and left-handed bookshelf that can be right-handed or left-handed who can sit comfortably on the desk.

In addition, the bookshelf according to the present invention can maintain a very stable structure because the center top plate is fixed to the chair, and the side top plate is rotated with respect to the center top plate, thereby switching from right-handed use to left-handed use, or from left-handed use. Switching to the handle can be made very easily.
