Description

Technical Field

[0001] This utility model relates to a support device for stringed musical instruments. Background Technology

[0002] Supports for stringed instruments such as guitars, basses, and double basses are known. As shown in Patent Documents 1, 2, and 3, stringed instrument supports are generally vertical supports.

[0003] On the other hand, among stringed instruments without a resonator or with a very small resonator, there exist instruments that produce sound primarily based on signals from detected string vibrations (here called electronic stringed instruments). Since electronic stringed instruments do not require a resonator, they are typically asymmetrical. Such stringed instruments are prone to rotation when hung vertically on a wall, etc., therefore, vertical support devices (stands) for electronic stringed instruments have been proposed.

[0007] Technical problem to be solved by the utility model

[0008] However, in order to provide stable support for electronic stringed instruments, the aforementioned support device has become a robust structure and is quite heavy. Therefore, carrying the support device along with the electronic stringed instrument is not easy. Thus, there is room for improvement considering both portability and stable support for the stringed instrument.

[0009] One of the objectives of this invention is to provide a string instrument support device that is highly portable and can support string instruments in a horizontal position.

[0010] Technical solutions for solving technical problems

[0011] According to one aspect of this utility model, a support device for a stringed instrument is provided, comprising: a support portion including a receiving surface for receiving the stringed instrument; a first foot portion including a pair of feet extending from both ends of the support portion along its length; and a second foot portion extending from the support portion between the two ends of the support portion, which rotates relative to the first foot portion about a rotation axis, thereby allowing the rotation position to be variable between a closed foot position and an open foot position; when the second foot portion is in the closed foot position, the first foot portion and the second foot portion are aligned along the axial direction of the rotation axis; and in a standing state where the second foot portion is in the open foot position and the front ends of the pair of feet and the front ends of the second foot portion are in contact with the ground, the receiving surface can cooperate with the ground to support the stringed instrument in a horizontal position.

[0022] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0023] Figure 1This is a side view of a support device for a stringed instrument and a stringed instrument according to one embodiment of the present invention.

[0024] As a stringed instrument 200 supported by the support device 100, in stringed instruments without a soundbox or with a very small soundbox, it is assumed to be an instrument that produces sound primarily based on the detected vibration signal of the strings (a so-called electronic stringed instrument). As for the type of stringed instrument 200, it is assumed to be a bass or double bass. It should be noted that the stringed instrument 200 is not limited to the instruments assumed above; acoustic stringed instruments can also be supported by the support device 100. The stringed instrument 200 has a body 60, on which a tailpiece 53 is mounted. The axis of the body 60 is set as C1.

[0025] exist Figure 1 The image shows an example of a stringed instrument 200 supported horizontally on a support device 100. A horizontally supported state is defined as a state where the angle between the axis C1 and the ground F is less than 45°.

[0026] Figure 2 , Figure 3 , Figure 4 , Figure 5 These are perspective views, front views, side views, and side views of the support device 100. The support device 100 has a first foot 10 and a second foot 20, and can change its state to a closed foot state and a closed foot state. Figure 2 , Figure 4 The middle indicates the open position of the support legs. Figure 3 , Figure 5 The symbol indicates the closed position of the support legs. The support device 100 is used with the support legs open when supporting the stringed instrument 200.

[0027] It should be noted that the stringed instrument 200 is typically carried in an instrument case such as a guitar case. The instrument case usually includes a pocket for storing small items such as sheet music and cables. The support device 100 is easily stored in this pocket by closing its legs. The detailed structure of the support device 100 will be explained below.

[0028] like Figure 2 , Figure 3 As shown, the support device 100 has a first foot 10, a second foot 20, a support portion 30, and a connecting portion 50. The first foot 10 includes a pair of feet 11 and 12. Feet 11 and 12 extend from the two ends (first end 30a and second end 30b) of the support portion 30 in the longitudinal direction. The second foot 20 extends from the support portion 30 between the first end 30a and the second end 30b in the longitudinal direction of the support portion 30 (e.g., at the central position).

[0029] The front end 11a of foot 11 and the front end 12a of foot 12 are connected by a connecting part 50. It should be noted that the support part 30 is integrally formed with the first foot 10, but it can also be formed as an independent component and fixed to each other. Furthermore, the connecting part 50 is integrally formed with the first foot 10, but it can also be formed as an independent component and fixed to each other. Additionally, the support part 30 can also be composed of two components that clamp the base of the second foot 20 from the front and back sides.

[0030] The second foot 20 can be rotated via a pivot 40 provided on the support 30. Figure 3 Centered on the first foot 10, it rotates relative to the second foot 20. The second foot 20 rotates about the rotation axis 40, allowing its rotational position to vary between the closed position (corresponding to the closed state) and the open position (corresponding to the open state).

[0031] like Figure 3 As shown, a first limiting part 13 is provided in the connecting part 50. A second limiting part 14 is provided in the support part 30. The first limiting part 13 restricts the rotational position of the second foot 20 to the closed position. The second limiting part 14 restricts the rotational position of the second foot 20 to the open position. Therefore, the first limiting part 13 and the second limiting part 14 function as limit stops, thereby restricting the rotational range of the second foot 20. Furthermore, it is easy to stabilize the rotational position of the second foot 20 in the open and closed positions. Moreover, since the first limiting part 13 is disposed in the connecting part 50, it can abut against the front end 20a of the second foot 20, thus the rigidity of the first limiting part 13 can be low, contributing to weight reduction.

[0032] It should be noted that the first limiting part 13 can be integrally formed with the connecting part 50, or it can be a separate component installed on the connecting part 50. The second limiting part 14 can be integrally formed with the support part 30, or it can be a separate component installed on the support part 30. It should be noted that providing either the first limiting part 13 or the second limiting part 14 is not mandatory.

[0033] The support part 30 includes a receiving surface 31 that supports the main body 60 of the stringed instrument 200. Figure 2 , Figure 3 A cushioning element (not shown) is provided on the receiving surface 31 to protect the stringed instrument 200, but the cushioning element is not necessary.

[0034] like Figure 4 As shown, the state in which the second foot 20 is in the open support position and the front ends 11a, 12a of the pair of feet 11, 12 and the front end 20a of the second foot 20 are in contact with the ground F is defined as the "standing state". In the standing state, the bearing surface 31 can support the stringed instrument 200.

[0035] The receiving surface 31 is inclined such that its height changes along the axis of the rotation shaft C0 when the surface is in a standing position. Figure 3 That is, the height gradually decreases from the first end 30a to the second end 30b. By setting such an inclination, the stringed instrument 200, which has an inclined surface on the side of the body 60 that serves as the supported part, can be horizontally and stably supported. It should be noted that the shape of the receiving surface 31 can be designed according to the shape of the supported stringed instrument 200, and it is not necessary to have an inclined shape. Therefore, the receiving surface 31 only needs to include the area where the height changes in the axial direction of the rotation axis C0 when standing.

[0036] The support device 100 in a standing position supports the stringed instrument 200, which is equipped with a tailpiece 53, in a horizontal position. Figure 1 , Figure 4 The state shown is such that the front end 53a of the tail column 53 is in contact with the ground F, and the bearing surface 31 of the support device 100 ( Figure 3 The side 60a of the main body 60 of the stringed instrument 200 is supported. That is, in the standing state, the bearing surface 31 cooperates with the ground F to support the stringed instrument 200 in a horizontal position.

[0037] Here, along the length direction (axis C1 direction) of the string instrument 200, the center of gravity G of the string instrument 200 is... Figure 1 The position of the tailpiece 53 is located between the support position that supports the stringed instrument 200 on the bearing surface 31. If the center of gravity G is located on the neck side compared to the support position, there is a risk that the tailpiece 53 will lift off the ground F and the neck side will contact the ground. However, since the center of gravity G is on the tailpiece 53 side compared to the support position, this situation can be avoided, and the stringed instrument 200 is stably supported. In addition, it is desirable for the center of gravity G to be located very close to the support position between the support position and the tailpiece 53. Because the center of gravity G is close to the support position, a large load caused by gravity in the direction perpendicular to the axis C1 is less likely to act on the tailpiece 53, thus reducing the burden on the tailpiece 53.

[0038] It should be noted that, Figure 1 The center of gravity G shown represents the position of the stringed instrument 200 along its length. In reality, there may be cases where the center of gravity G is not located on the axis C1, but the position of the center of gravity G along the length of the stringed instrument 200 relative to the support position has the relationship described above, thereby achieving stable support.

[0039] like Figure 1As shown, there are cases where a side plate unit 55 and a knee rest 52 are installed in a stringed instrument 200, such as a so-called electronic stringed instrument. There are also cases where the side plate unit 55 has a wrist rest 51 (protrusion) protruding from the main body 60 of the stringed instrument 200. The dimensions of the support device 100 are designed so that these wrist rests 51 and knee rests 52 do not contact the ground F.

[0040] And, as Figure 2 As shown, when the second foot 20 is in the open support position, a space S is formed between the pair of feet 11 and 12 for the wrist rest 51 to enter. Therefore, when supporting the stringed instrument 200 in a standing position, as... Figure 1 As shown, the wrist rest 51 is positioned so that it extends through the space S, thereby avoiding interference between the wrist rest 51 and the support device 100. Therefore, it is easy to stably hold stringed instruments 200 that do not have a soundbox or have a small soundbox.

[0041] When the second foot 20 is in the closed position, the first foot 10 and the second foot 20 are arranged along the axis of rotation C0. Figure 3 , Figure 5 Therefore, the thickness of the support device 100 in the closed state can be reduced, making it easier to carry the support device 100 and to store it in the aforementioned pocket.

[0042] And, as Figure 5 As shown, viewed from the axial direction of the rotation axis C0, the front ends (11a, 12a) of the first foot 10 and the front end 20a of the second foot 20 are both tapered at the front. Therefore, the support device 100 with the feet closed can be easily inserted into the pocket from the front end side where the front ends taper.

[0043] Reference Figure 1 , Figure 4 The design examples of suitable dimensions for the support device 100 are explained.

[0044] exist Figure 4 In the standing position shown, the load of the stringed instrument 200 is applied in the direction indicated by arrow 201. From the viewpoint that the first foot 10 mainly bears the load of the stringed instrument 200 while reducing the burden applied to the second foot 20, the direction of arrow 201 is approximately parallel to the length direction of the first foot 10.

[0045] like Figure 1 As shown, the length of the first foot 10 is defined as L. The height of the highest position of the support 30 in the standing state is defined as H. The angle formed by the first foot 10 and the second foot 20 on the ground F side in the standing state is defined as the foot opening angle θ.

[0046] Taking into account the representative dimensions of the supported stringed instrument 200, firstly, the total length EL from the front end 53a of the tailpiece 53 where the telescoping position is shortest to the supported position of the stringed instrument 200 ( Figure 1 The length is approximately 1013 mm. The protrusion AL of the wrist rest 51 from the axis C1 is approximately 1013 mm. Figure 1 The diameter is approximately 159 mm. The dimensions for properly supporting such a stringed instrument 200 and ensuring portability are studied as follows.

[0047] The length L is less than 360mm, the height H is 180mm or more, and the leg opening angle θ is 17° to 125°. Therefore, by setting L < 360mm, it can fit into the aforementioned pocket while ensuring good portability. By setting H ≥ 180mm, protrusions such as the wrist rest 51 are prevented from contacting the ground F. By setting 17° ≤ leg opening angle θ ≤ 125°, the support device 100 is unlikely to tip over, easily providing stable support for the stringed instrument 200.

[0048] Next, the width and even the thickness of the first foot 10 will be studied.

[0049] The direction orthogonal to the extension direction of the first foot 10 and the axial direction of the rotation axis C0 is defined as the thickness direction of the first foot 10. This will be observed from the side. Figure 4 When ), the maximum width in the thickness direction of each pair of feet 11 and 12 is set to B1. On the other hand, when viewed from the front ( Figure 3 When the rotation axis C0 of each pair of feet 11 and 12 is oriented, the maximum width is set as B2. The maximum width B1 is smaller than the maximum width B2.

[0050] This design allows the wall thickness of the first foot 10 to be obtained primarily along the axial direction of the rotation axis C0. Therefore, by maximizing the maximum width B2 and minimizing the maximum width B1, necessary rigidity can be ensured, and the foot can be compactly stored in the aforementioned pocket when closed.

[0051] According to this embodiment, when the second foot 20 is in the closed support position, the first foot 10 and the second foot 20 are arranged along the axial direction of the rotation axis C0. Furthermore, in the standing state where the second foot 20 is in the open support position and the first foot 10 and the second foot 20 are in contact with the ground F, the bearing surface 31 cooperates with the ground F to support the stringed instrument 200 in a horizontal position. Therefore, the support device 100 has excellent portability and can support the stringed instrument 200 in a horizontal position.

[0052] Furthermore, since it has a connecting part 50 that connects the front ends 11a and 12a of a pair of feet 11 and 12 to each other, it can improve rigidity and easily achieve weight reduction.

[0053] Furthermore, when the second foot 20 is in the open position, a space S is formed between the pair of feet 11 and 12 for the wrist rest 51 protruding from the string instrument 200 to enter, thus making it easy to stabilize string instruments that do not have a soundbox or have a small soundbox.

[0054] Furthermore, when viewed from the axial direction of the rotation axis C0, the front ends (11a, 12a) of the first foot 10 and the front ends 20a of the second foot 20 are both tapered, making it easy for the support device 100 in the closed state to enter the aforementioned pocket.

[0055] Furthermore, the receiving surface 31 is provided with an inclination that matches the side shape of the main body 60, thus enabling the stringed instrument 200, which has an inclination on the side of the main body 60, to be horizontally and stably supported.

[0056] Furthermore, regarding the dimensions of the support device 100, by setting L < 360mm, H ≥ 180mm, and 17° ≤ foot opening angle θ ≤ 125°, it is possible to achieve effects such as ensuring portability, preventing the wrist rest 51 from contacting the ground F, and providing stable support for the stringed instrument 200.

[0057] Figure 6 This is a front view of the support device 100 in a modified example. The connecting portion 50 is not essential in the support device 100. Figure 6 In the variant example shown, relative to Figure 3 The example shown differs in that the link 50 is removed.

[0058] In this case, since there is no connecting part 50, it is impossible to configure a first limiting part 13 to restrict the rotational position of the second foot 20 to the closed position of the support. Therefore, a limiting part equivalent to the first limiting part 13 can be configured on the support part 30.

[0059] It should be noted that, in Figure 6 In the variant shown, the following was cancelled. Figure 3 In the example shown, an inclination is provided on the bearing surface 31. It should be noted that an inclination can also be provided. Other structures in the modified support device 100 are similar to... Figure 3 The example shown is the same.

[0060] The present invention has been described in detail above based on preferred embodiments, but the present invention is not limited to these specific embodiments and is intended to include various forms without departing from the spirit and scope of the present invention.
