Abstract

PROBLEM TO BE SOLVED: To reduce the number of part items and to reduce the manufacturing cost by arranging a product in a die in the attitude of the minimum machining depth of the resin molding die, and forming several music paper antislip protruded stripes having a slope nearly perpendicular to the split face of the resin molding die on the upper face of a music paper receiver. SOLUTION: A music stand 1 and a music paper receiver la are integrally resin-molded. The split face of a resin molding die is set on a straight line connecting the upper rear end of the music stand 1 and the lower front end of the music paper receiver 1c, and a product is arranged in the die in the attitude of the minimum machining depth of the resin molding die. Multiple music paper antislip protruded stripes 1c having a slope nearly perpendicular to the split face of the resin molding die are formed on the upper face of the music paper receiver 1a. A music stand device for a musical instrument capable of reducing the number of part items as compared with a conventional music stand device for a musical instrument and capable of reducing the die cost due to the minimum machining depth of the molding die can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a mechanical structure capable of manufacturing a music stand for a musical instrument at low cost, making a musical score less slippery during performance, and making the surface of the music stand wood-finished. It is.

[0002]

2. Description of the Related Art In a recent music stand for musical instruments,
Generally, a music rest is fixed on a top plate constituting a part of a musical instrument housing, and a wooden music rest is inserted at a predetermined angle behind the music rest. One of the reasons is that a convex band for non-slip music is required on the upper surface of the music rest, but it is difficult to form a non-slip convex band for music by integrally forming with the music rest. Another reason is that the surface of the music rest should be made of wood, but it is difficult to finish the wood by integrally forming with the music rest, and it was difficult to manufacture the music rest at low cost.

The above-mentioned conventional music stand for musical instruments will be described below with reference to the drawings.

FIG. 7 is an external view showing a conventional music stand for musical instruments, and FIG. 8 is a schematic sectional view of FIG. 7 and 8
In the figure, reference numeral 21 denotes a music stand, which is fixed to a top plate 23 with screws 22. Reference numeral 24 denotes a plug-in wooden music stand, and a shaft 25 is fixed by screws 27 via metal fittings 26. Reference numeral 28 denotes a bearing, which is adhesively fixed to the top plate 23 and into which a shaft 25 is inserted. Reference numeral 29 denotes a music score.
Placed on top of A convex band 21a for preventing the music score from slipping is formed on the upper surface of the music table 21.

[0005]

However, in the above-mentioned conventional configuration, there is a disadvantage that it is difficult to manufacture the music stand at low cost because the music stand and the music rest are composed of separate parts.

The present invention solves the above-mentioned conventional problems, and provides a music stand for musical instruments that can be manufactured at a low cost by improving the structure to have an extremely small number of parts to be manufactured as compared with the related art. be able to.

[0007]

In order to achieve this object, a music stand for a musical instrument according to the present invention comprises a music stand and a music stand formed integrally with each other to reduce the number of parts and to process a molding die. The product is placed in the mold in a posture that minimizes the depth, thereby reducing the cost of the mold. In addition, in order to prevent the score from slipping when performing, the score slide has a slope that is approximately perpendicular to the split surface of the molding die that is provided on a straight line that connects the upper rear end of the music rest and the lower front end of the music rest. A convex band for stopping can be formed on the upper surface of the music stand. Further, in order to make the surface of the music stand wood-finishable, a concave band is provided at the boundary between the music stand and the music rest, and foil such as a woodgrain pattern can be thermally transferred to the music stand side from the concave band.

[0008] With this configuration, it is possible to provide a music stand for musical instruments which can be manufactured to have a structure in which the number of parts to be manufactured is extremely small as compared with the conventional one and can be manufactured at low cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of a music stand for musical instruments according to an embodiment of the present invention, FIG. 2 is a schematic sectional view of FIG. 1, FIG. It is an arrow view. 1, 2, 3, and 4, reference numeral 1 denotes a music stand, and a music stand 1 a is integrally formed. 2
Is a shaft, which is pressed into the boss 1b. Reference numeral 3 denotes a bearing, which is bonded and fixed to the top plate 4 and into which the shaft 2 is inserted. Reference numeral 5 denotes a music score, and a music rest 1a of the music rest 1
Placed on top of A convex band 1c for preventing the music score from slipping is formed on the upper surface of the musical score receiving portion 1a.

FIG. 5 is a view showing a mold structure of the music stand body, and FIG. 6 is a detailed view of a portion B in FIG. 5 and 6, a straight line C is a split surface of the resin molding die, and the upper rear end D of the music rest 1 and the lower front end E of the music rest 1a are connected to each other to form a resin molding die. Machining depth is minimized. The straight line F is in a direction perpendicular to the straight line C, that is, in the mold opening / closing direction, and can form a slope of the musical score non-slip convex band 1c on the upper surface of the music table receiving portion 1a.

In FIG. 3, by providing a concave band 1d at the boundary between the music rest 1 and the music rest 1a, a foil such as a woodgrain pattern can be thermally transferred to the H surface.

As described above, according to the present embodiment, the music rest and the music rest are integrally formed to reduce the number of parts, and the product is placed in a posture in which the working depth of the molding die is minimized. It is possible to provide a music stand for musical instruments that can reduce the cost of the mold by disposing the music stand inside.

[0014]

As described above, according to the present invention, the music rest and the music rest are integrally formed by resin molding, and the resin rest is formed on a straight line connecting the upper rear end of the music rest and the lower front end of the music rest. Set the split surface of the molding die, place the product in the die with the posture that minimizes the processing depth of the resin molding die, and set the slope approximately perpendicular to the split surface of the resin molding die. Since a plurality of non-slip belts can be formed on the top of the music rest, the number of parts can be reduced and the working depth of the molding dies can be minimized compared to the conventional music stand for musical instruments. As a result, it is possible to provide a music rest apparatus for a musical instrument that can reduce the cost of a mold. In addition, since a concave band is provided at the boundary between the music stand and the music rest, and a foil such as a woodgrain pattern can be thermally transferred to the music stand side with the concave band as a boundary, a music stand for musical instruments that can finish the surface of the music stand with a wood finish. Can be provided.
