Description

Class desk with movable chair {DESK HAVING MOVABLE CHAIR}

The present invention relates to a lecture desk integrated with a chair, and more particularly, to a lecture desk having a movable adjustable chair that can be used to move the chair forward and backward.

In general, schools and academies use a desk with an integrated chair to increase the space utilization of the desk.

However, such a desk is usually produced based on the standard physical condition of a general learner (user), so it may not fit well depending on the learner.

In other words, if the learner has a larger body than the standard value, the book holder is close to the chair, which is inconvenient.

Therefore, when used for a long time or repeatedly, the fatigue of the learner may be increased, and if it is excessive, it may be hardened to an unbalanced learning posture, and the learning efficiency is also reduced.

The present invention was devised in view of the above circumstances, and provides a lecture desk with a movable adjustable chair that can be used to move the chair forward and backward according to a learner's physical condition and learning attitude. There is this.

Specific means of the present invention for achieving the above object,

As a lecture desk for moving and adjusting the chair 20 integrated with the backrest plate 40,

Between the chair 20 and the support frame 30 connecting the book support plate 40, the movable rail 51 is fixed to the chair 20 side, the fixed rail 52 is the support frame 30 Two pairs of rail assemblies 50A and 50B fixed to the side and slidably movable to each other;

The rail assemblies 50A and 50B are provided with fixing levers 60A and 60B for fixing the moving positions of the moving rails 51 to the fixing rails 52, respectively, and at the same time, the fixing levers 60A and 50A ( 60B) is connected to the connecting rod 70 and configured to rotate together;

The lever handle 62 is provided on either of the fixing levers 60A or 60B, and the chair 20 can be moved back and forth by manipulating the lever handle 62. It is characterized in that the fixing is possible.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

The lecture desk 10 of the present invention is characterized in that the chair 20 integrated with the book support plate 40 can be adjusted before and after movement according to the convenience of the learner.

To this end, between the chair 20 and the support frame 30 connecting the book support plate 40, the movable rail 51 is the chair 20 side via the front and rear support members 15 and 16 as a medium. Fixed rail 52 is fixed to the support frame 30 side is provided with two pairs of rail assemblies 50A, 50B, which are slidably movable.

In the rail assembly 50A, 50B, fixing levers 60A, 60B for fixing the moving position of the moving rail 51 to the fixed rail 52 side are hinged on the moving rail 51 side, respectively. These fixed levers 60A and 60B are connected to each other by an interconnection rod 70 and are configured to rotate together.

The moving rail 51 side is provided with a plurality of engaging holes (51a) in the longitudinal direction so that the one end side stopper 61 portion of the fixed lever (60A, 60B) can be inserted respectively. (See Figure 4)

The lever knob 62 is provided on either of the fixing levers 60A or 60B. The lever handle 62 is preferably positioned at the bottom of the chair 20 to allow free hand manipulation, and the lever handle 62 does not interfere with the learner when the learner approaches the chair 20. Are arranged to avoid.

In the present embodiment, the fixing levers 60A and 60B are connected to the springs 80, respectively, so that the fixing levers 60A and 60B are always rotated in the fixed direction by the spring 80 force. That is, one end of the spring 80 is connected to the moving rail 51 side and the other end is connected to the fixed lever 60B side as shown in FIG.

In the present invention, all four legs 31 installed in the chair 20 and the book support plate 40 may be integrally formed with the support frame 30 or may be installed separately from the support frame 30.

Here, the rail assemblies 50A and 50B are not limited to the sliding structure of the embodiment and include various forms in which the two moving rails 51 and the fixed rails 52 are slidably coupled to each other.

In addition, the fixing lever 60A, 60B and the locking hole 51a of the fixing rail 52 may be modified in various forms to those skilled in the art in order to fix the movement position of the moving rail 51 to the fixing rail 52 side. .

The operation of this embodiment configured as described above will be described.

First, the stopper 61 of the fixed lever 60A is inserted into one of the engaging holes 51a of the movable rail 51 of the rail assembly 50A, so that the chair 20 is in a fixed state.

In this state, when the user operates the lever handle 62 in the X direction while sitting on the chair 20, the fixing levers 60A and 60B simultaneously rotate through the interconnecting rod 70 to fix the lever 60A. The stopper 61 of 60B is separated from the engaging hole 51a of the moving rail 51 of the rail assembly 50A, 50B, respectively.

In this state, the chair 20 is moved to a desired position. That is, when the book support plate 40 is felt away from the user, the chair 20 is pulled forward to be the position of the advantage chain, and conversely, when the book support plate 40 is felt close to the user, the chair 20 is positioned at the point of dashed line. Push it backward so that it moves.

When the moving position of the chair 20 is determined, the fixing lever 60A is fixed to the moving rail 51 by using the lever knob 62 again.

In this case, the adjusted chair 20 is simply fixed.

In this way, the chair 20 can be adjusted back and forth according to the user's convenience, thereby having a suitable learning posture and improving learning efficiency.

As described above, according to the present invention, it is possible to freely adjust the chair part of the lecture desk before and after to have an advantage of providing an optimal learning posture for a user.
