Description

[Detailed description of the invention] This proposal relates to a mounting table on which, for example, a horizontally long tabletop keyboard instrument is placed. , the depth of the mounting section can be adjusted.

A conventional tabletop keyboard instrument mounting stand has two legs made of hollow cylindrical material connected and fixed in a facing manner, and a mounting section is fixed above the legs with a metal fitting. The spacing, the angle of the placement part provided on each leg, and the depth of the placement part cannot be adjusted.

Therefore, it is necessary to form a mounting stand individually depending on the model of the tabletop keyboard instrument.

This proposal was proposed in view of the above, and will be explained below based on the embodiments of the drawings. 1 is a vertical portion 1a extending diagonally upward, and a horizontal portion 1b extending horizontally from the lower end of the vertical portion 1a. A pair of left and right legs are made of pipe material and are bent and formed, and both legs 1, 1 are connected by a connecting part 2 so that the interval length can be adjusted. An insertion opening 3 is formed.

The above-mentioned connecting part 2 consists of a horizontally oriented rectangular cylindrical first frame member 4 which has a bracket 4' at one end attached to the vertical part 1a of one leg part 1 and fixed with screws, etc., and a bracket 5' at one end to the other side. It consists of a horizontally oriented rectangular cylindrical second frame member 5 attached to the vertical portion 1a of the leg portion 1 and fixed with screws, etc., and by inserting the second frame member 5 into the first frame member 4, the left and right legs are assembled. The parts 1, 1 can be connected, and the distance between the two leg parts can be adjusted by changing the insertion state.

Further, above the legs 1, 1, there are attached tightening parts 6, 6 which can adjust the mounting angle of the mounting part, which will be described later.

The tightening parts 6, 6 are connected to the brackets 7, 7 at one end.
is fixed above the legs 1, 1, and the other end has a through hole 8, 8 in the center and teeth 9, 9 formed on the inner surface.
Auxiliary pieces 13, 13 have toothed portions 12 on the inner surface that mesh with the toothed portions 9, 9, and screw rods 11, 11 are bored in the center, and adjustment screw portions 14, 14 screwed onto the screw rods 11, 11. The auxiliary piece 13 is placed on the tip of the arm 10 so that the teeth 9 and 12 mesh with each other, the threaded rod 11 is passed through the hole 8, and the adjustment screw part 14 is screwed together.

Such tightening parts 6, 6 are adjustable screw parts 14,
Turn the operating rods 14, 14' extended from 14 to loosen the screw rod 11, and loosen the toothed portions 12, 12 of the auxiliary pieces 13,
12 from the teeth 9, 9 of the arms 10, 10, the auxiliary piece 13 becomes rotatable. And auxiliary piece 13
Adjust the screw rod 11 to an appropriate state using the adjusting screw part 14.
When the auxiliary piece 1 is tightened, the teeth 9 and 12 engage and the auxiliary piece 1 is tightened.
3 is fixed. On the other hand, the instrument mounting part 15 includes a mounting piece 16 provided at the tip of the mounting pieces 13a, 13a provided upward from the upper end of the auxiliary pieces 13, 13, and a mounting piece 16 provided on the bottom surface of the end of the mounting piece 16. It consists of a letter-shaped movable piece 17.

An upright edge 1 is provided at one end of the mounting piece 16 described above.
6' and a long hole 18 is bored at the other end, and an upright edge 1 is formed at one end of the movable piece 17.
7' and a through hole 19 is bored in the other end, so that the end of the movable piece 17 faces the lower surface of the placement piece 16, and is fixed to the through hole 19 from the long hole 18 of the placement piece 16. A movable piece 17 is made movable along a long hole 18 through a rod 20.

Therefore, the depth of the mounting piece 15 can be adjusted by moving the movable piece 17.

Further, the mounting part 15 fixed to the auxiliary piece 13 of the tightening part 6 is fixed to the mounting piece 13a by operating the adjusting screw part 14 and shifting the toothed part 12 of the engaged auxiliary piece 13 from the toothed part 9 of the arm 10. The angle can be adjusted because it rotates.

In order to place, for example, a tabletop keyboard instrument on a tabletop keyboard instrument having such a configuration, the space between the legs 1 must be adjusted by the connecting portion 2 to match the width of the tabletop keyboard instrument, and the movable piece 17 of the tabletop keyboard instrument 15 must be placed on the tabletop keyboard instrument. The placement piece 16 is moved along the long hole 18 to match the depth of the tabletop keyboard instrument. Thereafter, the tabletop keyboard instrument is placed on the mounting stand.

Loosen the adjustment screw part 14 of the tightening part 6 and remove the auxiliary piece 1.
When the tooth part 12 of No. 3 is removed from the tooth part 9 of the arm 10,
Since the auxiliary piece 13 can be rotated, the angle of the mounting section 15 can be adjusted, and by meshing the teeth again and tightening the adjustment screw section 14, it becomes easier for the player to play the instrument on the mounting section 15. can be set in the state.

In summary, according to the present invention, musical instruments of any size can be accommodated by the configuration of the connecting part using a frame material that allows the length of the gap between the left and right legs to be adjusted, and the configuration that allows the depth of the mounting part to be changed. Furthermore, any type of musical instrument can be supported reliably, extremely easily, and in a stable state. Furthermore, since the angle of the mounting part can be adjusted using the tightening part, the instrument can be tilted to a position that makes it easier for the player to play.This allows the player to play for long periods of time without getting tired, and improves playing technique. You can also do it.

In addition, since an opening is formed at the upper end of the leg, an auxiliary leg having a placing part can be connected.
It can be used as is even when the musical instrument is played in two stages, upper and lower, and has high practical value.
