Abstract

PURPOSE: An AV room desk is provided, which makes enables other people to pass only by sitting and standing up operation. CONSTITUTION: An AV room desk comprises: a main supporter(40) forming a leg of a desk in bottom plane front region of an upper plate of a desk; a mobile rotary shaft(20) which is connected to a main supporter, can move from an angle which is horizontal to the surface to an angle which is perpendicular to the surface; an upper plate which is separated, can move separately to one seat which one man can use; a groove or a guard step preventing the fall of all kinds of the goods located on a desk.

Description

Table of auditorium that can afford room for route}

The present invention relates to a desk used in a large lecture room or an audio-visual room, where several rows of seats are formed in a narrow space to accommodate a large number of students or crowds in a narrow space, and a person sits on an access path in access to the seats in a single row. A desk designed to alleviate the discomfort associated with a desk layout that cannot be seated in the desired seat and must be moved out of the way by a person on the path. The present invention relates to a desk having a folding chair that can be folded down and seated when a person in a front row sits on a front face, and a desk having a similar structure and disadvantages.

The conventional desk was able to secure a passage space by folding the chair attached to the back row when it rises from the seat. However, this secured space is so narrow that it is impossible for more than two people to stand in one place, making it very difficult for a person sitting on a passage to pass without going out.

In this conventional desk and seat structure, the person sitting on the path can secure a space for the person who wants to pass even if they do not come out and get out of the way. I could pass it.

In order to solve the problem, an axis was placed in front of the upper plate of the desk so that the upper plate could rotate about the axis. Therefore, as the top plate rotates, the space of the seat where the top of the desk is located is secured, and the person sitting in the seat rises and rotates the desk and moves forward one step. Free space will be secured.

In addition, the rotating top plate has a cylindrical pedestal with a radius of the length from the rotating shaft to the end of the top plate in order to prevent it from falling down due to gravity when objects including writing instruments are placed on it. Prevent falling.

Therefore, the present invention serves to create a passage that can be passed by other people only by moving the seat to secure the free space by moving the top of the desk.

Details of the present invention are as follows. As shown in Figure 2, the top plate of the desk is a basic structure that can be rotated to the cabinet around the axis attached to the support for supporting the desk. At this time, when the person sitting in the seat stands up and moves forward, the chair of the seat in which the seat was originally seated folds backward, creating a space where one person can pass. Structure.

In the case of the classroom desk, students will use various texts and writing instruments on the desk to take classes. When rotating the top plate, various objects on the desk will slide down due to gravity. Picking up the fallen object again is a very cumbersome action that requires bending your back and knees. It is supported by a cylindrical shape.

As a technique for implementing the rotation of the top plate follows the method shown in Figures 3 and 4. 3 shows a main support 40 constituting the legs of the desk and a rotating shaft 20 connected vertically to the upper end thereof, and a supporting shaft 30 attached to the rotating shaft to support the top plate to be maintained in the horizontal direction with the ground. Is attached.

The top plate of the desk is screwed by a bearing 22 which is configured not to fall over a certain angle by the support shaft 30. Such a bearing 22 is shown only on the left side, and the right side has a mirror-shaped bearing and a support shaft, and has a structure connected to both bottom surfaces of the top plate.

The process of the support shaft 30 can be made at the same time when machining the rotary shaft 20, but the connection with the main support 40 of the desk is inconvenient, so as to attach the support shaft 30 and the rotary shaft 20 as shown in FIG. Drill a vertically penetrating hole and connect it there with a connecting pin 70 so that it can be assembled.

Using the above-mentioned desks as one basic unit, the user can arbitrarily connect a series (series) of the user to configure a row of seats in a lecture room or an audio-visual room.

Figure 1 is a side view of the usual appearance of the desk.

2 is a view from the side when the top plate of the desk is rotated and lifted.

Figure 3 is a view showing a rotation axis for implementing the rotation of the top plate of the desk.

4 is a view of the bearing attached to the top plate of the desk to allow connection to the shaft.
