Description

Stand equipped with high and low controling

The present invention relates to a remarking table used in a local autonomous conference hall, auditorium, church, etc., and relates to remarks provided with a height adjustment function to more easily adjust the height of the remarks according to the position of a person.

In general, the present invention relates to remarks provided with a height key height adjustment function that makes it easier to adjust the height according to the position of a person.

In local meetings, auditoriums, and churches, most people who speak, lecture, or speak will stand at the top. A microphone is provided and used.

However, these remarks are generally produced in a state in which the height or length is fixed.

Therefore, when the user using the podium is small, there is a problem that the user climbs on the pedestal to speak, lecture, or speak by using a separate foot pedestal, and the height of the microphone must be readjusted.

In addition, when the user using the remarks is tall, the user has to use the bent or the TV monitor far away from the waist and be used to adjust the height of the microphone.

The present invention has been made in view of the above circumstances, and a technical object of the present invention is to provide a remarks stand having a height adjustment function that allows the height of the remarks to be easily adjusted according to the height of the user.

The remark stand provided with a height adjustment function according to the present invention is provided with a fixed plate having a plurality of insertion holes formed therein for fixing the driving unit, and a remark stand main body provided with a support for supporting a transport stand and a transport stand. It characterized in that it comprises a drive unit provided with a drive shaft provided in the drive motor and the fixed plate formed in the support motor and the fixing plate formed in the support plate formed in the support nut formed in the spiral hole fastened to the support nut.

In addition, a timing gear is provided on the spiral shaft and the driving motor, and a timing belt is coupled to the timing gear provided on the spiral shaft and the driving motor, so that the rotational force of the driving motor is transmitted to the spiral shaft.

In addition, a plurality of withdrawal holes are formed in the fixed plate formed on the support and the support, the transport nut is fastened to the lower end of the withdrawal hole formed in the transport and the spiral shaft is rotatably at the lower end of the withdrawal hole formed in the support using a fastening member In addition to the fastening, the spiral shaft is inserted into the conveying nut so that the conveying nut is vertically conveyed along the spiral axis.

According to the present invention described above, it is possible to provide a speech stand equipped with a height adjustment function that allows the height of the speech stand to be more freely adjusted and more precisely adjust the height of the speech stand according to the height of the user using the speech stand.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings. The embodiments described below are illustrative of one preferred configuration of the present invention, and examples of such embodiments are not intended to limit the scope of the present invention. The present invention can be variously modified without departing from the technical idea thereof.

The remarks with height adjustment function according to the present invention is provided with a remarks main body 10 and is provided with a drive unit 20 to adjust the height of the remarks.

The remark bar main body 10 is provided with a support (11) for supporting the conveying table 11 and the conveying table 11 is vertically conveyed.

The transfer table 11 has a shape in which the lower side is opened, and the diameter thereof is set to a size such that the support 12 can be inserted into the inside of the transfer table 11.

The inner side of the transfer table 11 is formed with a fixing plate (11a) is fixed to the upper side of the drive unit (20). A plurality of drawing holes 11c are formed in the fixing plate, and the transfer nut 23 of the driving unit 20 is provided at the lower end of the drawing holes 11c.

On the upper surface of the transfer table 11 is formed a TV monitor which is a document glass and an electronic document glass on which a user's basic belongings and remarks, such as books or manuscripts used for lectures, can be placed. In addition, a switch 11b for operating the driving unit 20 is formed on an upper surface of the transport table 11.

The support 12 has a shape in which the upper surface is opened is formed in the lower side. In addition, a fixing plate 12a is formed at the inner side of the support 12 to which the lower side of the driving unit 20 is fixed. A plurality of drawing holes 12b are formed in the fixing plate 12a, and the forming positions of the drawing holes 12b are formed at the same positions as the drawing holes 11c formed in the fixing plate 11a. The fixing plate 12a is provided with a driving unit 20.

 The diameter of the support 12 is set smaller than the inner diameter of the support so that the support 12 can be inserted into the inside of the transport (11).

The driving unit 20 includes a driving motor 21 for driving the driving unit 20, a plurality of spiral shafts 22, and a transfer nut 23 which is vertically conveyed along the spiral shaft 22.

The drive motor 21 is provided with a timing gear 21a on the rotating shaft so that the rotating shaft is rotatably fastened through the fastening member 24 at the lower end of the fixed plate 12a.

The spiral shaft 22 has a timing gear 22a at its lower end and is fixed to the lower end of the insertion hole 12b formed in the fixing plate 12a through the fastening member 24. The spiral shaft 22 fixed to the lower end of the insertion hole 12b extends above the insertion hole 12b.

The feed nut 23 has a spiral hole 23b formed at the center thereof. The transfer nut 23 is fastened through a fastening member such as a bolt, although not shown in the drawing, at the lower end of the insertion hole 11b formed in the fixing plate 11a formed in the transfer table 11.

The spiral shaft 22 is inserted into and coupled to the spiral hole 23b formed in the transfer tuft 23. The spiral shaft 22 inserted and coupled to the spiral hole 23b is drawn out to an upper side of the insertion hole 11b formed in the fixing plate 11a.

The timing gear 21a provided in the driving motor 21 and the timing gear 22a provided in the spiral shaft 22 are fastened by the timing belt 25. Therefore, when the drive motor 21 is rotated rotationally, the spiral shaft 22 is rotated by the timing belt 25.

5 is an operational state diagram of the remarks stage.

In the speech stand provided with the height adjustment function of the present invention, the user presses the switch 11b to adjust the height according to his key while standing in front of the speech stand while the power is supplied from the outside.

When the user presses the switch 11b, the driving motor 21 of the driving unit 20 is operated, and the rotating shaft of the driving motor 21 rotates to rotate the timing gear 21a provided on the rotating shaft.

When the timing gear 21a is rotated by the rotation shaft, the spiral shaft 22 coupled to the driving motor 21 and the timing belt 25 rotates.

When the spiral shaft 22 is rotated as described above, the feed nut 23 fastened to the feed table 11 is vertically conveyed along the spiral shaft, and thus the feed table 11 is transferred based on the support 12. The height of 11 is adjusted. At this time, the user stops the operation of the switch 11b when the height of the remarks is set to a height suitable for his height to fix and use the remarks.

Therefore, the speaker with the height adjustment function of the present invention can freely adjust the height to match the height of each user using the speaker, it is possible to adjust the height more accurately and efficiently.
