Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a tripod stand, and particularly to a structure of a tripod stand capable of tiltably holding a main column.

(Prior Art) For example, in a conventional tripod stand for musical instruments, an upper holding member that pivotally attaches an upper portion of each leg to a tripod support portion at a lower portion of a main pillar and a joint arm connected to an intermediate portion of each leg is pivoted. A lower holding member to be worn is generally provided. In the tripod stand of this structure, the upper holding member is usually configured to be movable along the main column, and the tripod portion can be opened / closed (folded) and the leg opening angle can be adjusted.

However, for example, when setting up multiple drum instruments, it may be desirable to hold a particular drum or equipment such as cymbals or microphones close to the performer side, but the conventional stand does not have a tilting function, so it is unavoidable. Boom is connected to the upper part of the main pillar of the instrument, and the instrument is held by the boom for playing.

However, connecting the boom to the upper part of the main pillar of the stand requires a special connecting device or member including the boom. Not only that, by connecting the boom to the upper part of the main pillar, the position of the center of gravity of the stand fluctuates greatly and becomes unstable, so there is always a risk that the stand will fall over for some reason.

Therefore, the applicant newly devised a structure of a tripod stand that can freely hold the main pillar in a tilted state. This structure will be described in detail in the following embodiments, but one of the tripods supporting the main pillar can move the main pillar independently of the other to tilt the main pillar to the one leg side. It was done like this.

(Problems to be solved by the invention) However, when one leg of the tripod supporting the main pillar is opened wide relative to the other two legs, the main pillar is moved toward the one leg side. Although it tilts, the larger the tilt, the worse the stability with respect to the side perpendicular to the tilt direction of the main pillar, and if a force is applied in that direction, the stand will easily fall even with a small force. A problem has arisen.

The present invention has been made in view of such problems, and an object thereof is to provide a tripod stand having a tilting function, which has higher stability.

(Means for Solving the Problem) That is, in order to solve the above-mentioned problems, one of the tripods supporting the main pillar moves independently of the other so that the main pillar is Proposed is a tripod stand which is configured to be tiltable to one leg side, and in which the attachment angle of the other two legs with respect to the main column is attached at an angle larger than a trisection angle (120 degrees). To do.

(Operation) Generally, the mounting angle of the tripod portion of the tripod stand with respect to the main column is a trisecting angle of a circle, that is, 120 degrees, as shown in FIG. 5 of the accompanying drawings. Then, as shown in the plan view of the figure, when the legs 21 are opened from the upright position indicated by the chain line and the main pillar 11 is tilted and held on the leg 21 side, the center of gravity of the stand is from G to G1 near the legs 21. Move to.

Therefore, the tip of the inclined main pillar of the stand (that is, the leg 21
A device attached to the side can be held more safely.

On the other hand, FIG. 6 is a plan view showing an example in which the mounting angle of the tripod is changed from the conventional trisecting angle A (120 degrees). That is, when the legs 21 are opened and the main pillar 11 is tilted toward the legs 21, if the mounting angle of each leg is the conventional trisecting angle A (120 degrees), it is formed at the landing point of the tripod. The triangle is an isosceles triangle whose two sides, which are the side surface portions with respect to the inclination direction, are longer than the bottom side, as shown by the dotted line in the figure, and has a shape that easily falls in the direction C (that is, sideways) perpendicular to the inclination direction. Therefore, the leg mounting angle formed by the main columns 11 and the legs 22 and 23 on the side opposite to the inclination direction is set to the conventional trisecting angle A.
Angle A1 which is a little larger than (120 degrees), that is to say 1
The stand can be reinforced laterally by being attached to the main pillar at an angle of about 30 to 145 degrees.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a main part of a tripod stand for musical instruments showing an example of the present invention, FIG. 2 is a perspective view showing a state where the stand is tilted, and FIG. 3 is a perspective view showing a state where the tripod part is folded. , FIG. 4 is an enlarged side view of the main part of the tripod, FIG. 5 is a top view of the main part of the tripod stand in which the mounting angle of the tripod is a trisection angle, and FIG. 6 is the tripod according to the present invention. And FIG. 7 is a side view of a tripod part showing another example.

The tripod stand 10 for musical instruments shown in FIG.
And a tripod 20, and the main pillar 11 has a telescopic pipe 1
2 is provided via the connecting portion 13. Main pillar 1
Although not shown here, an appropriate tool or holding portion such as a holder, a bracket, or a microphone is formed at the end of the telescopic pipe 1.

The tripod portion 20 has legs 21, 22, 23 and joint arms 26, 27, 28 connected to the middle portions of the legs, respectively. The legs 21, 22, and 2 are attached to the tripod support portion 15 below the main pillar.
3, an upper side holding member 30 for axially attaching the upper part of 3 and a lower side holding member 4 for axially attaching the joint arms 26, 27, 28.
0, 50 are provided.

And in this embodiment, in particular, the joint arm 26 of the leg 21 is independent of the joint arms 27 and 28 of the other legs along the main pillar 11,
It is held by the movable lower holding member 50 so as to be movable.

FIG. 1 shows a state in which the main pillar 11 is upright, and FIG. 2 moves the movable lower holding member 50 upward to further open the leg 21 to the outside to move the main pillar 11 to the leg 21 side. It is a figure of the state which made it tilt.

As can be better understood from the enlarged side view of FIG. 4, the upper holding member 30 is pivotally connected to the upper portions of the legs 21, 22, and 23 by shaft pins 35, respectively, and the member main body is It can move along the pillar 11. Reference numeral 36 is a screw member for adjusting and fixing.

The lower holding member 40 is fixed to the lower end of the main pillar 11,
The tips of the joint arms 27 and 28 of the legs 22 and 23 are connected by a shaft pin 45. The tips of the joint arms 27 and 28 are connected to the legs 22 and 23 by a shaft pin 29.

The movable lower member 50 can slide along the main column 11, and is connected to the tip of the joint arm 26 of the leg 21 by a shaft pin 55. Reference numeral 56 is a screw member for adjusting and fixing.
The other end of the joint arm 26 is connected to the leg 21 by a shaft pin 29 like the others.

Then, when the movable lower member 50 is slid upward to open the leg 21 to the left in the figure as indicated by an arrow U in FIG. 4, the entire main pillar is on the leg 21 side as shown in FIG. Tilt to. The screw member 56 for adjusting and fixing the movable lower member 50 is tightened and positioned at a position of a predetermined inclination angle. If necessary, a stopper 60 for memory is provided, and it is convenient for positioning when reusing if a stopper 60 for memory is slid and brought into contact with the upper surface side of the movable lower member 60 and fixed with the fixing screw 66. .

When the main pillar 11 is tilted and held, the upper holding member 30 can be freely moved. It is needless to say that each leg and joint arm are pivotally connected to each other by means of shaft pins, so that it is possible to freely cope with a change in angle at each connecting portion.

FIG. 3 shows a state in which the tripod portion 20 is folded. In this case, the upper holding member 30 is slid upward and the legs are folded.

As mentioned above, in this tripod stand 10,
One leg 21 of the tripod 20 supporting the main pillar 11 moves independently of the other two legs 22 and 23, so that the main pillar 11 can be tilted toward the one leg 21 side. However, in the present invention, the other two legs 22, 23 are attached to the main column 11 at an angle larger than the trisecting angle (120 degrees).

As already mentioned in the section of the action, generally, the mounting angle of the tripod with respect to the main pillar in the tripod stand is usually a trisecting angle of the circle (120 degrees), but in this conventional type, As can be better understood from FIGS. 5 and 6, when the main pillar 11 is tilted and held, the main pillar 11 has a shape that easily tilts in a direction C (that is, to the side) perpendicular to the tilt direction.

Therefore, in this invention, as shown in FIG. 6, the leg mounting angle formed by the legs 22 and 23 on the opposite side to the inclination direction and the main pillar 11 is slightly larger than the conventional trisecting angle A (120 degrees). The stand is reinforced laterally by being attached to the main pillar at an angle A1, that is, an angle of about 130 to 145 degrees.

Of course, in this case, the leg mounting angle B1 formed by the legs 21, 22 and the main column 11, and the leg mounting angle B2 formed by the legs 21, 23 and the main column 11 are all trisecting angles ( It is desirable that the angle is smaller than 120 degrees and the angle is the same in terms of balance.

(Other Embodiment of Tilt Mechanism) Next, another example of the tilt mechanism of the tripod stand will be described.

Although the examples of FIGS. 1 to 4 described above are examples in which the movable lower member is provided, the exact same operation can be realized by the movable upper member.

FIG. 7 relates to another embodiment and has a movable upper member 72. That is, in order to change the degree of spread of the leg 21 independently of the other legs 22 and 23, a case where the lower holding member 50 coupled to the joint arm 26 of the leg 21 is moved as in the above-described example, Alternatively, as in this example, two methods for moving the upper holding member 72 coupled to the upper portion of the leg 21 can be considered.

In the example of FIG. 7, the upper portion of the leg 21 is axially attached to the movable upper member 72 via a shaft pin (not shown) as in the example of FIG. The movable upper member 72 is configured to be slidable along the main pillar 11.

The upper portions of the other legs 22 and 23 are pivotally attached to the upper holding member 31. In this example, the upper holding member 31 can also slide along the main pillar. The joint arms 26, 27, 28 of the legs 21, 22, 23 are pivotally mounted on a common lower holding member 41 fixed to the lower ends of the main columns.

The reference numerals common to those in FIG. 4 among the reference numerals in FIG. 7 represent the same members.

(Effects) As shown and described above, in the tripod stand according to the present invention, one leg of the tripod portion supporting the main pillar moves independently of the other to move the main pillar to the first one. In the structure which is tiltable to the leg side, the mounting angle of the other two legs with respect to the main pillar is attached at an angle larger than the trisection angle (120 degrees). The stability on the side of the right angle is improved, and even if it is tilted greatly, it is safe and can be used with confidence.
