Description

[Detailed explanation of the idea] This invention relates to a drum stand.

Generally, drums are used by being held on stands for playability, operability, and acoustics.

Conventionally, for example, a stand for a bass drum has a pair of vertically fixed supporting members, and a shaft provided at the upper end of the supporting member at a position symmetrical to the body of the bass drum is rotatable. A type that could be attached to hold the bass drum was used.
However, in conventional devices of this type, the drum is attached directly to the stand using a shaft, so the reverberations of the drum are transmitted directly to the stand, producing an unpleasant sound, and the drawback is that the pure drum sound is not radiated. It was hot.

Therefore, in order to eliminate such drawbacks, the first
A stand for a drum as shown in FIGS. 3 and 2 has been proposed (see US Pat. No. 3,780,613). This stand has a ring member 1 arranged so as to surround a drum D as shown in FIG. This ring member 1
The drum D is attached concentrically to the holder 4 through an elastic holder 4, and the drum D is held in a floating state by utilizing the elastic force of the holder 4. More specifically, the holder 4 includes a screw with a ring hole 5 fixed to the outer periphery of the body S of the drum D, and the ring member 1, as shown in FIG.
The two fasteners 6 are attached to the two fasteners 6 by the hook portions of the springs 7 which are passed through the ring holes of the ring hole screw 5 and attached to both ends. This holder 4 is composed of a ring member 1 and a cord 8 that is locked.
They are arranged at four locations on the circumference at approximately equal intervals. The cord 8 is elastic and flexible, and is set in a U-shape with both ends locked, and the drum D is pulled in a well-balanced manner at the middle of the cord 8. It is designed to be kept as is.

However, according to this stand, the drum D is held at four points using the elasticity of the cords 8, and the locking is performed by pulling both ends of the cords 8 of each holder 4. Therefore, the installation work of drum D is extremely troublesome. Moreover, in that case, the work must be carried out while supporting the heavy bass drum D in a well-balanced manner, making the work even more troublesome and difficult. Therefore, the problem often arises that the balance is lost and the drum is set in an off-center position.

This idea was made in view of the above circumstances,
By improving the placement of the holder and its structure,
To provide a drum stand on which a drum can be set extremely easily and without shifting.

The feature of this invention is that the drum is supported at three points by arranging holders at three places in the gap between the ring member and the drum in the circumferential direction, and the holder is attached to the first support attached to the ring member side. A metal fitting, a second support metal fitting attached to the drum side, and an annular member that is spanned between the hook portions formed on each of the first and second support metal fittings while maintaining a predetermined connection distance. The point lies in the structure.

An embodiment of this invention will be described below with reference to FIGS. 3 to 9.

FIG. 3 is an overall front view showing a bass drum being held by the stand of this invention, and FIG. 4 is a side view thereof. 11 in the figure is the base (leg body)
This base 11 is connected to a bolt 15 by a pair of base blocks 13 having casters 12 on the lower surface and one telescopic base pipe 14.
The base blocks 13 are assembled in an H-shape using the base blocks 13, and are constructed so that the distance between both base blocks 13 can be adjusted. The base pipe 14 is a combination of a main pipe 16 and two slide pipes 17, and is made to be expandable and retractable, and after adjusting the length, it is fixed with a bolt 18 (see Fig. 7). .

A support pipe (support member) 19 is vertically provided at the center of each of the base blocks 13.
In this case as well, the support pipe 19 is removably fixed with bolts 20 as shown in FIG. These support pipes 19 have a slight bend in the middle, and when attached to the base 11, the width between the upper ends of both support pipes 19 is wider than between the lower ends.

A ring member 21 having a substantially annular shape is supported between the upper ends of the support pipe 19 thus attached so as to be rotatable about an axis extending in the radial direction of the ring member 21. In this case, the ring member 21 is symmetrically divided into two parts, which are connected by a connecting fitting 22 and a bolt 23, and a clamp 24 provided at the upper end of the support pipe 19 by a shaft 22a integrally formed on the outside of the connecting fitting 22. (support part).

Details of the clamp 24 are shown in FIGS. 5 and 6. The clamp 24 is attached to the support pipe 19

A shaft 22a extending outward in the radial direction of the ring member 21 from a connecting fitting 22 provided on the ring member 21 is sandwiched between the two recesses 26a and 27a, and is supported by being pressed from above and below. It's getting old.

One end of the holding piece 27 is connected to one end of the clamp body 26 by a horizontal pin 28, and is rotatable around the axis of the pin 28, and a vertical groove 27b is formed at the other end. ing.

Further, a planting screw 29 is vertically set in the position of the clamp body 26 corresponding to the vertical groove 27b of the holding piece 27, and the holding piece 27
7 is moved so as to cover the upper surface of the clamp body 26, the upper part of the implant screw 29 penetrates upward through the vertical groove 27b of the holding piece 27. A fly nut 30 is screwed into the upper end of this screw 29. If the fly nut 30 is tightened tightly, the shaft 22a of the ring member 21 will be fixed so that it will not move, and if it is slightly loosened, the shaft 22a will rotate. If the nut 30 is loosened further and the nut 30 is removed, the shaft 22a, that is, the ring member 21 can be removed from the support pipe 19.
It can be removed from the top.

Furthermore, the ring member 21 supported on the upper end of the support pipe 19 is provided with holders 31 and 31' for holding the drum D at three locations on its circumference. The positions where it is provided are at the bottom of the ring member 21 and at two points on the left and right on the diagonally upper side,
The position is symmetrical. The opening angle θ of the two upper points is appropriately set, such as 90° or 60°, depending on the size and type of the drum D to be set.

Of these holders 31, 31', the upper holder 31 is shown in FIG. 8, and the lower holder 31' is shown in FIG.
It is as shown in the figure. Although there are some differences between the two, both holders 31 and 31'
Also, the first support metal fittings 32, 32' fixed to the ring member 21, the second support metal fitting 33 attached to the body S of the drum D, and the ring-shaped belt ( Annular member) 34.

First, to describe in detail what is shown in FIG. 8, the first support fitting 32 on the side of the ring member 21 is
It has a hook part 32a at the tip and a threaded part 32b at the base end, the hook part 32a is directed inward of the ring member 21, the threaded part 32b is passed through the ring member 21 from the radial direction, and the threaded part 32b has a threaded part 32b at the tip. A cap nut 35 is screwed into and fixed to the ring member 21. In addition, the second support fitting 3 on the drum D side

Then, the hook portion 3 of the first support fitting 32
A ring-shaped belt 34 is stretched between the hook portion 33a of the second support fitting 33 and the hook portion 33a of the second support fitting 33.
The ring-shaped belt 34 is a single belt formed into a ring shape and tied together with rivets or the like, and it is preferable to use a belt that is flexible but not very elastic. Therefore, the ring-shaped belt 34
is bridged between the hook portion 32a of the first support metal fitting 32 and the hook portion 33a of the second support metal fitting 33, so that the hook portions 32a of the first support metal fitting 32 and the hook portion 33a of the second support metal fitting 33 are
This means that a predetermined connection distance is maintained between a and 33a.

The holder 31' shown in FIG. 9 differs from that shown in FIG. 8 only in the following points. That is,
The threaded portion 32b' of the first support fitting 32' on the side of the ring member 21 is relatively long, and a chiyo nut 37 is screwed in instead of the aforementioned cap nut 35, and the chiyo nut 37 is tightened. By loosening or loosening the first support metal fitting 32', the distance between the two hook parts 32a' and 33a can be adjusted by moving the position of the first support metal fitting 32' and adjusting the force for pulling and supporting the drum D. There is.

When assembling this stand, first connect the base pipe 14 to the base block 13 to assemble the base 11, then fix the support pipe 19 vertically to the base 11, and then assemble the ring member 21 to form the connecting fitting 22. This is attached to the upper end of the support pipe 19 using the shaft 22a, and at the same time, the width of the base 11 is adjusted and fixed with the bolt 18 to complete the assembly.

When setting the drum D on the stand assembled as described above, lift the drum D and position it inside the ring member 21 fixed so as not to rotate, and at the same time, place the drum D at two points on the top of the body S of the drum D. The second support fitting 33 fixed to the ring member 21 is made to correspond to the first support fitting 32 on the ring member 21 side,
The ring-shaped belt 34 is passed around the hook portions 32a, 33a of both metal fittings 32, 33, and then the first and second supporting metal fittings 32', 33 of the lowermost holder 31' are passed around.
A ring-shaped belt 34 is attached to the hook portions 32a' and 33a of the
, and by tightening the chiyo nut 37, pull the drum D downward.

As a result, the drum D is pulled and balanced by three points on the circumference, and is firmly held in a floating state. Then, the ring member 21 is rotated together with the drum D as appropriate according to the performer's preference, and stopped at an appropriate posture, and the clamp 24 is then fixed to the nut 3.
