Description

ELECTRONIC TEACHING DESK

The present invention relates to an electronic teaching apparatus, and more particularly, to an electronic teaching apparatus which is easy to use and disassembly and which has an improved locking function.

Generally, a lecture is a table in which a teacher or lecturer places a book at a school, a school, or a corporation when a plurality of students are educated.

Conventionally, a lecture desk simply plays a role of placing a book or the like to be referred to by a teacher or an instructor. Recently, an electronic lecture desk equipped with a variety of educational materials such as a monitor, a computer, and a projection has appeared due to the development of various educational materials.

[0003] With the technology relating to the electronic teaching apparatus, there are disclosed an electronic teaching apparatus which is provided with a built-in educational material, a multi-purpose teaching electronic apparatus equipped with a monitor, and recently, an electronic teaching apparatus equipped with a real-

Here, the actual visual perception device is a product composed of optical system and electronic parts, and it is connected to projection TV and PC, and it shows the enlargement of various materials (pictures, photographs, books, objects, creatures, slides / OHP films, And equipment used in lecture.

However, in the case of the electronic teaching apparatus according to the prior art, a variety of teaching equipment equipments such as a computer and a projection are simply installed or placed on the inside or outside of the teaching desk. There is a problem that it is not easy to manufacture and maintain because it is manufactured in a somewhat complicated custom form.

In addition, in the conventional electronic lectern, in particular, the monitor installed on the upper surface is fixed in a horizontal state or fixed in an inclined state. In the case of the electronic lecture, the lecturer observes the monitor The latter is inconvenient, and in the latter case, when the lecture is conducted without using a monitor, it is difficult to place the lecture text or the like due to the interference of the monitor, resulting in various problems such as reduced user convenience.

In order to improve this, it is possible to easily perform manufacture and maintenance, and in particular, it is possible to change the angle of rotation of the monitor installed on the upper surface to increase the convenience of the user. December 15, 2011).

As another example, an electronic teaching apparatus capable of adjusting the tilt of a monitor is disclosed in Japanese Patent No. 1436312 (Aug. 26, 2014).

As another example, a wireless electronic teaching desk having increased installation and ease of use by eliminating a line has been disclosed in Laid-Open Patent Application No. 2014-0049529 (Apr. 25, 2014).

However, since the monitor installed in the electronic teaching desk shown in the Registration Practice No. 0457480 and the Registration No. 1436312 does not have a separate protection measure, there is a great risk of breakage in that it is a lecture for playful students.

In order to prevent this, when a monitor protective cover is installed, space required for connection between a computer main unit and a peripheral device (monitor, mouse, keyboard, etc.) connected thereto is narrow. Therefore, In case of connecting wires, the wiring process is very complicated and inconvenient, and is especially inconvenient when it is reinstalled after separation for maintenance.

In addition, theft is a concern but there are few means to prevent it. Of course, a mouse or a keyboard can be put in a drawer with a lock and locked with a padlock, but it is difficult to disassemble the monitor once it is installed.

In addition, although a cover or a top plate is slid over the top of the monitor for the purpose of utilizing a book or a teaching material in order to use the monitor when using the monitor, it is easy to slide and open anybody because there is no separate locking device. Once installed, it is equipped with a latch structure to prevent it from being easily released when it is slid for use. When it is necessary to separate it for maintenance, it is necessary to completely release the latch structure itself, There are also disadvantages that exist.

On the other hand, if wireless is used as disclosed in Laid-Open Patent Application No. 2014-0049529, the convenience of installation and disassembly is increased because there is no need to wire the computer main body and peripheral devices among the above-mentioned problems. However, Furthermore, in case of wireless, a battery must be provided for wireless operation, and it is frequently inconvenient to use because it must be replaced periodically. Moreover, when the battery replacement cycle passes, the problem of not being able to take a class at all occurs, and there is a lot of inconvenience because the battery remaining amount can not be checked every time.

Therefore, although the electronic teaching desk used mainly in schools is designed to be wired rather than wireless, the problems of the above-mentioned registration practice 0457480 and registered patent No. 1436312 are included.

At this time, the latch 236 operates in the same manner as in Fig. 4A.

When releasing the lock, since the hook 234 'pushes up the upper end of the opening portion of the clip-like elastic piece CP by rotating the key bundle 232 in the opposite direction, the lower end of the opening portion is attached to the upper end The cover locker 240 can be naturally rotated reversely to release the lock state.

It goes without saying that these examples are merely preferred embodiments or modifications, and that they can be freely modified within the scope of the same technical idea.

On the other hand, an upper plate 400 is fixed to an upper end of the main body housing 200.

The upper plate 400 is a plate-shaped member having a thickness such that the upper surface thereof is inclined.

In particular, as shown in FIGS. 1 and 3, a keyboard receiving part 300 is provided on one side of the upper plate 400, preferably on the side where the lecturer stands, in a sliding manner.

Since the keyboard storage box 300 can be drawn out, it is preferable that the keyboard K be placed on the keyboard, taken out if necessary, and stored if not necessary.

A mouse pad 320 is disposed on one side of the upper surface of the upper plate 400. The upper surface of the upper surface of the upper surface of the upper surface of the upper plate 400 And a control panel (CT) is installed above the mouse pad 320 with an interval therebetween.

At this time, in the case of the mouse pad 320, it is particularly preferable that the upper end of the seating surface is formed deeper than the lower end so that the mouse does not flow down when the mouse is placed.

The rest of the touch pad or the control panel CT is the same as that of a conventional electronic desk, so a detailed description thereof will be omitted.

Here, the keyboard receiving part 300 and the touch pad receiving part 310 are configured to be smoothly drawn out by the guide rail 330.

At this time, the guide rail 330 includes a rail housing 332, a floating rail 334, and a fixed rail 336, as shown in the enlarged sectional view in FIG.

At this time, the rail housing 332 is fixed to both side surfaces of the groove, into which the storage bag of the upper plate 400 can be inserted.

The rail housing 332 has a substantially ⊂ shape and a flow rail 334 is inserted into the bent rail housing 332. The rail housing 332 has bent ends of the rail housing 332 in an outward direction A convex housing groove 338 is formed.

In addition, the ball bearings 340 provided at both ends of the bent and bent portions of the flow rail 334 are seated in the housing groove 338 and can be moved a certain distance along the housing groove 338.

The ball bearings 340 are moved so that the floating rails 334 coupled with the ball bearings 340 reciprocate within the rail housing 332 by a predetermined distance.

At this time, the flow rail 334 is also formed in a shape of '⊂' corresponding to the rail housing 332.

In addition, the structure in which the ball bearings 340 are installed on the flow rail 334 has a structure in which the diameter of the balls constituting the ball bearings 340 in the longitudinal direction at predetermined intervals at both ends of the flow rail 334 And a plurality of balls are inserted into the holes, thereby constituting the ball bearings 340. [0051]

The stationary rail 336 is inserted into the movable rail 334. The opposite end of the stationary rail 336 is inserted into the receiving compartment or the keyboard receiving part 300 or the touch pad receiving part 310, Respectively.

When the monitor M is not used to prevent cutting or breakage of the monitor M, the upper part of the monitor M may be closed by the cover 400 and be locked through the locking unit.

In addition, it is also possible to provide a simple fixed monitor other than the angle-adjustable monitor M as described above. This may be a simple monitor monitor M having a constant inclination, excluding the fluid cylinder 410, the first and second links 420 and 430, ) May be mounted.

At this time, when only the monitor M is mounted, a protective member 440 may be further provided on the upper portion of the monitor M.

The protection member 440 can be separated from the upper plate 400 while protecting the monitor M, thereby providing convenience of wiring work when the monitor M is installed.

In addition, the protective member 440 is fixed to the upper plate 400 using bolts or screws after the monitor M is installed, so that the protective member 440 can be disassembled and assembled when the malfunction is repaired, but the monitor M is normally protected.

Of course, in the case of the monitor M capable of adjusting the inclination angle including the fluid cylinder 410, when the protection member 440 is installed, it is difficult to operate due to interference. In this case, the protection member 440 Since the protection member 440 is not provided, it is possible to freely perform wiring through the upper portion of the space S, so that there is no difficulty in wiring.

One side of the space S in which the monitor M is installed in the upper plate 400 is opened and the cover 500 is assembled to be slidable in the left and right direction through the opened portion.

The cover 500 is slid in one direction from the upper plate 400 to allow the monitor M to be used by exposing the monitor M and the cover 500 itself provides a space for placing various teaching materials do.

In particular, since the cover 500 is assembled on the inclined upper plate 400, the cover 500 itself is inclined. In order to prevent this, the cover 500 is provided at the lower end of the cover 500 with a long rod-shaped locking protrusion 510 protruding in the longitudinal direction of the cover 500, Can be configured.

In addition, the latching protrusion 510 functions as a gripping member which can be opened and closed more easily by allowing the cover 500 to be grasped when the cover 500 is slid.

Here, as one of the most characteristic features of the present invention, the cover 500 can be completely and easily separated from the top plate 400 very easily.

That is, the cover 500 is normally slid in the left and right direction and stops at a certain point. However, when the cover 500 needs to be separated, the cover 500 can be completely separated from the upper plate 400 by a simple operation, ) Can be operated in a completely disassembled state, so that it is easy to work because it provides a sufficient working space, especially when the monitor (M) is separated.

To this end, cover rails 10 are installed on both sides of the cover 500.

The cover rail 10 is similar to the above-described guide rail 330, but is further improved. As shown in an enlarged cross-sectional view of FIG. 2 and in FIG. 5, Shaped first fixed rail 20 which is inserted into the opening of the first fixed rail 20 and a second movable rail 20 which is fitted in the opening of the first fixed rail 20, A first ball bearing B1 interposed between both ends of the first and second curved ends of the first and second flow rails 30 and 30 and a bent both ends of the first and second flow rails 30 and 30, Shaped second fixed rail 40 which is fitted in the opening of the second flow rail 32 and has an opposite shape fixed on the upper plate 400, (Not shown) formed at both bent ends of the second flow rail 32 and between both bent ends of the second flow rail 32 and the bent both ends of the second fixed rail 40 The second ball bearing (B2) .
