For example, in a first conventional musical instrument (Japanese Utility Model Publication No. 57-51416, 51417, 51418), a pair of lids is configured to be detachable from the instrument main body, and functions as lids when carrying or storing. At the time of installation, the lid is detached and fixed to the bottom of the main body with a screw through an auxiliary tool so that the lid is used as a leg.
[0004]
In the second conventional musical instrument (Japanese Utility Model Laid-Open No. 6-16990), leg members are foldably attached to left and right ends of the musical instrument main body, and when the leg members are folded, a box-shaped member provided at the bottom of the musical instrument main body is provided. The leg member is stored in the storage section.
[0005]
[Problems to be solved by the invention]
However, in the above-mentioned first conventional musical instrument, when storing or using, it is necessary to remove the lid, properly arrange auxiliary tools and fix them with screws, and vice versa. And the work of storing is complicated. Further, since the lid, the auxiliary tool, the screw body, and the like are separated from the main body, there is a possibility that these parts may be lost.
[0006]
Further, in the second conventional musical instrument, since the leg member does not double as the lid, the performance operation unit is not protected. On the other hand, if the lid is separately provided, the configuration becomes complicated, and it is difficult to make the device compact.
[0007]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and has as its object a simple structure and easy assembling and storing work without fear of losing parts, but having a good quality in use.

Further, the upper front portion 10A3 of the mouth stick portion 10A is also formed in an R shape. The upper front portions 10La and 10Ra and the upper rear portion 10B2 guide the lid / leg 20L / R to properly regulate the position in the front-rear direction when the lid / leg 20L / R is closed to function as a lid. The upper front portion 10A3 of the mouth stick portion 10A also plays an auxiliary role.
[0018]
FIG. 4 is a partially enlarged view of the vicinity of the hinge mechanism 13A as viewed from the front. FIG. 6A shows a state in use, that is, a state in which the lid / leg 20R is vertically suspended, and FIG. 5B shows a state in which the lid / leg 20R is rotating between the vertically suspended state and the closed state. Indicates the status.
[0019]
The hinge mechanism 13A includes plate portions 13A2 and 13A3 rotatably attached around a rotation shaft 13A1. The plate portion 13A2 is fixed to the side plate portion 20R4 of the lid / leg portion 20R, and the plate portion 13A3 is fixed to the lower surface 10a of the main body 10. The other hinge mechanisms 13B to 13D have the same configuration.
[0020]
Small legs 15 and 16 (see FIGS. 1 and 3 for the small legs 16) are fixed to the lower surface 10 a of the main body 10. The small leg portion 15 is formed by integrally forming a leg portion 15a and a spacer portion 15b thinner than the leg portion 15a. The small leg portion 15 is formed to have a length extending between the hinge mechanism portions 13A and 13B, but is divided into two parts, and is separately disposed behind the hinge mechanism portion 13A and in front of the hinge mechanism portion 13B. You may.
[0021]
The spacer portion 15b is formed to be slightly thicker than the combined thickness of the plate portion 13A2 and the plate portion 13A3 of the hinge mechanism portion 13A, and as shown in FIG. It abuts on the side plate portion 20R4 to prevent the load of the main body 10 from being directly applied to the plate portions 13A2, 13A3. The leg 15a contacts the installation surface G when the lid / leg 20R is closed or during assembly, and prevents the body 10 from directly contacting the installation surface G as shown in FIG. The small leg portion 16 is similarly configured symmetrically to the small leg portion 15.
[0022]
In such a configuration, in order to assemble it so that it can be used from the time of non-use shown in FIG. 2, first, the locking tools 22A to 22D are detached from the locking parts 12A to 12D, and the lid / leg 20L / R is hinged. As shown in FIG. 1, both free ends 20La and 20Ra are opposed to the installation surface G by rotating the mechanism portions 13A to 13D in the door opening direction. At this time, the lids and legs 20L and 20R function as legs supporting the main body 10 via the spacers 15b and 16b of the small legs 15 and 16 (the reference numeral 16b is not given). Then, the anti-rollover rod 14 is removed from the holding groove portion 10B3 of the back portion 10B, and this is locked in the locking holes 20L3b, 20R3b of the lid / leg portions 20L, 20R, thereby reinforcing the main body 10 mainly in the left-right direction. It improves stability and prevents rollover. The user normally plays while sitting on a chair in this state.
[0023]
On the other hand, in order to store, the reverse process is performed. First, the anti-rollover rod 14 is pulled out from the locking holes 20L3b and 20R3b, and is fitted and held in the holding groove 10B3. Then, the lid / leg portions 20L and 20R are rotated in the door closing direction. At this time, the upper and lower ends 10L, 10Ra of the left and right ends 10R, 10R, the upper rear 10B2 of the back 10B, and the upper front 10A3 of the mouth bar 10A, respectively, are formed in the front-rear direction. The trajectory of the lid / leg 20L / R is regulated, and smooth rotation in the door closing direction is ensured. When the lid / leg 20L / R comes into contact with the lid receiving portions 10A1 and 10B1, as shown in FIG. 2, the lid / leg is located at a substantially central portion in the longitudinal direction of the main body 10 above the keyboard portion 11. Both free ends 20La, 20Ra of the portions 20L, 20R are closely opposed to each other. At this time, the lid / leg 20L / R functions as a lid that covers the main body 10. Note that the lid / leg 20L / R does not interfere with the rollover prevention rod 14 due to the escape portions 20L3a and 20R3a provided on the back plates 20L3 and 20R3. Finally, the locking tools 22A to 22D are locked to the locking portions 12A to 12D, so that a state suitable for storage and transportation is achieved.
[0024]
According to the present embodiment, the lid / leg 20L / R has a two-body configuration, each having a length of about half of the entire length in the longitudinal direction of the main body 10, so that the lid / leg 20L / R functions as a leg in the vertically erected state. The height of the main body 10 is appropriately secured, and the height is suitable for sitting on a chair and playing. Moreover, since the lid / leg 20L / R is connected to the left and right ends 10L and 10R of the main body 10, the main body 10 is stably held. Therefore, good performance operability can be ensured. In addition, when the lid / leg 20L / R functions as a lid, the keyboard 11 is protected and made compact to facilitate storage and transportation. In particular, since the lid / leg 20L / R is configured as a dust removal type, the main body 10 is widely and appropriately covered, and the protection of the keyboard 11 is excellent. Further, since the lid / leg 20L / R doubles as a lid and a leg, the configuration is simplified by reducing the number of parts. Therefore, it is easy to assemble and store with a simple configuration, and while maintaining good performance operability during use, it is possible to make the performance operation unit compact while protecting and storing the storage and transportation.
[0025]
In the present embodiment, the rollover prevention rod 14 is provided as a preferable configuration for ensuring the stability of the main body 10 after assembly and preventing the rollover. However, the present invention is not limited to this. When the 20L / R is in the hanging state, a lock mechanism for automatically locking the small legs 15, 16 and the lid / leg 20L / R or the main body 10 and the lid / leg 20L / R is provided. Is also good. In this way, the anti-rollover rod 14 becomes unnecessary, the assembly and storage operations can be performed only by turning the lid / leg 20L / R, and separate accessories and the like are not required. Disappears.
[0026]
In the present embodiment, a keyboard instrument has been described as an example. However, the present invention is not limited to this. For example, the present invention can be applied to various instruments that are played stationary, such as a steel guitar, a koto, a xylophone, and an iron koto. .
[0027]
In the present embodiment, the lid / leg 20L / R is rotatably connected to the left and right ends 10L and 10R of the main body 10 so as to open and close in the left and right directions. Any structure may be used as long as it is connected to the vicinity of the unit via a hinge mechanism. For example, it may be configured such that it is rotatably connected to the mouth bar portion 10A and the back portion 10B of the main body 10, and the lid / leg portion is opened and closed in the front-rear direction. In this case, the height of the main body 10 at the time of use is low, but it is suitable for a musical instrument such as Taisho Koto who sits and plays.
