Description

  The present invention relates to a portable case for storing a keyboard wind instrument.

  The keyboard wind instrument is usually stored in a case and carried for use by elementary school students in the classroom, taking into account movements at home and school, and in the classroom and music room or outside the classroom. When using a keyboard wind instrument in a music room, it is necessary to place the case on a desk and play it while watching the textbook and music score in the open state. When using the case as a music stand, open the case. The instrument body is placed inside and the performance hole is attached to the body. Also, when carrying, the keyboard wind instrument must be firmly fixed inside the case so that it is not damaged. Furthermore, it is also necessary to store a table pit, a stand pit, an instruction manual, and the like inside the case.

  There are two types of conventional cases: those molded from plastic as a raw material by blow molding (called hard cases) and those sewn using plastic sheets or cloth materials (called soft cases). The hard case is rigid and is most effective for protecting the stored keyboard wind instruments, and can be used as a music stand, but it can be painful if it hits the body when carrying it, and it is heavy. The soft case is flexible and does not hurt when hit, and it is lightweight, but most of the slide fasteners do not go around the hinge part, and it is inconvenient that it can not be used unless it is taken out from the case once. Yes, it is necessary to install new parts as a holding structure such as a table stool and a stand stool that could be molded with a hard case of plastic molded products, to support textbooks and music scores Is not strong enough for flexibility.

  In contrast, few technical improvements have been proposed, but there are few. For example, recently there is JP 2007-24951 relating to a flute musical instrument case, but this is a hard case that is neither lightweight nor flexible, and requires a function as a holding structure or a music stand. In addition, Japanese Utility Model Publication No. 55-6247, which is a reference document relating to the examination, is a so-called hard case for a storage case for a keyboard wind instrument, and there is no suggestion for solving the above-mentioned problems. .

JP 2007-24951 A Shokai 55-6247

  The present invention has been made by paying attention to the above points, and the problem is that a portable storage case for a keyboard wind instrument composed of a so-called semi-hard case having moderate rigidity and flexibility, and a stab mouth for playing a table, The purpose is to provide a holding structure such as a door for the use or a function to support textbooks and musical scores. Another object of the present invention is to provide a portable storage case for a keyboard wind musical instrument that effectively protects the instrument body and is easy to use.

In order to solve the above problems, the present invention is a portable case for storing a keyboard wind instrument,
The case body is formed of a flexible material, and includes a lower case for placing the instrument body and an upper case for covering the instrument body placed on the lower case. High and low at the front, low at the rear, low at the front of the upper case and high at the rear, with a height difference between the front and rear, and an inclined boundary connecting the above height differences diagonally on the left and right sides of the lower case and the upper case The upper case and the lower case are hinged at the rear, so that the upper case is hinged at the rear. Rotating around the center of the upper case, and a means of tilting rearward with the corner portion on the back of the upper case as a fulcrum is provided.

  The portable storage case for a keyboard wind instrument of the present invention belongs to a so-called semi-hard case in which the case body is molded from a flexible material. The material that forms this type of semi-hard case is often manufactured by molding using a composite material of plastic and cloth, etc., but it has a thin-walled structure and has flexibility and elasticity. It is lightweight.

  The case main body is molded, for example, from a material having flexibility as described above, and includes a lower case for placing the musical instrument main body and an upper case for covering the musical instrument main body placed on the lower case. The boundary between the lower case and the upper case is high at the front of the lower case and low at the rear, low at the front of the upper case and high at the rear, and there is a difference in height between the front and rear. The section is divided vertically by a boundary line connecting the above-mentioned height differences diagonally. Therefore, a high form at the rear part of the upper case moves away the fulcrum when the upper case is opened from the lower case.

  The upper case and the lower case are hinged at the rear of the boundary line, so that the upper case can be opened by rotating around the hinge part. The upper case is tilted backward and stands up. That is, when the upper case is opened on the desktop of the storage case of the present invention due to the difference in height at the boundary between the lower case and the upper case, the storage case is in contact with the surface of the table rather than the distance r1 from the lower surface of the lower case to the hinge portion. Since the distance r2 from the corner on the back of the upper case to the hinge is longer, the upper case stands up at a certain angle S beyond the upright position, and has a function to support textbooks and musical scores (Fig. 6B).

  The upper case and the lower case are hinge-coupled at the rear part, and are joined so as to be opened and closed by a fastener provided at the edge of the opening along the boundary line. As the case internal structure, it is desirable that the lower case has a protruding partition portion at the bottom of the inner surface to which the leg portion of the instrument body is received and fixed. The leg part of the instrument body is fixed so as not to move by engaging with the protruding partition part. The partition portion may be provided at the rear portion with respect to the musical instrument main body, and the front portion of the musical instrument main body can be restrained by engagement with a high portion at the front portion of the lower case.

  The lower case is preferably a space for placing the pipe portion of the table clerk attached to the instrument body, and a holding portion for the buttock, either before or after the protruding partition part to which the leg portion of the instrument body is fixed. Has behind. The empty space and the holding portion for the shed can be set between the projecting partition and the lower portion at the rear of the lower case.

  In addition, it is also desirable that the lower case has a holding part for the reed shed on the side of the protruding partition part in which the leg part of the instrument body is received and fixed. And if the upper case has an inward protrusion that touches and holds the rear upper part of the instrument body placed on the lower case, the rear upper part of the inner surface can be used for carrying. The keyboard wind instrument will be firmly fixed inside the case.

  Since the present invention is configured and operates as described above, in a portable storage case for a keyboard wind instrument composed of a so-called semi-hard case having flexibility, it is possible to hold a table mouthpiece, a performance mouthpiece, etc. The structure and the function to support textbooks and scores are provided. Another object of the present invention is to provide a portable storage case for a keyboard wind instrument that can effectively protect the instrument body and is easy to use.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 is a front view showing an example of a portable storage case 10 for a keyboard wind instrument according to the present invention. A case main body 11 is molded from a flexible material and a lower case on which a musical instrument main body 20 is placed. 12 and an upper case 13 covering the instrument body 20 placed on the lower case 12.

  The lower case 12 and the upper case 13 are such that the lower case 12 is higher at the front part 14 and lower at the rear part 15, the upper case 13 is lower at the front part 16 and higher at the rear part 17, and there is a difference in height between the front and rear. The left and right side portions of the case 12 and the upper case 13 are divided into upper and lower portions by an inclined boundary line that obliquely connects the height differences appearing there (see FIGS. 2 and 3). In the portable storage case 10 of the present invention, when the musical instrument main body is placed on the lower case and played, the one closer to the performer is defined as the front, and the far one is defined as the rear.

  Thus, the case main body 11 has the dividing boundaries between the lower case 12 and the upper case 13 as the edges 18 and 19 of the opening, and the upper case 13 and the lower case 12 are hinged at the rear part thereof. Thereby, the upper case 13 is configured to be rotatable about the hinge portion 21. As shown in FIG. 6A, the hinge portion 21 is arranged such that the lower rear portion 15 of the lower case 12 and the higher rear portion 17 of the upper case 13 are arranged back to back, and the upper end portion outside the lower rear portion 15 of the lower case 12; It is desirable that the upper end portion outside the high rear portion 17 of the upper case 13 (actually the lower end portion because it is back to back) is connected by the hinge member 22. In the illustrated example, when both ends of the hinge member 22 are sewn to the respective case sides, the lower end of the hinge member 22 is folded back into a “shi” shape, and the sewn portions 23a and 23b are formed like a bag stitch. Processing is performed so as to be hidden (see FIGS. 6A to 6C). The illustrated hinge member 22 is made of a belt-like cloth material, and is provided in a range extending over almost the entire width of the case main body in the left-right direction.

  In the storage case 10 of the present invention, the front and rear portions 14 and 15 of the lower case 12 and the front case 16 and the rear portion 17 of the upper case 13 are provided with a height difference between the lower case 12 and the lower case 12. When the upper case 13 is opened, the corner 17 of the rear portion 17 positioned below the upper case 13 is supported as a fulcrum and tilted rearward. That is, when the storage case 10 of the present invention is opened, the distance from the corner of the back surface of the upper case 13 in contact with the table surface 26 to the hinge portion, rather than the distance r1 from the lower surface of the lower case 12 to the hinge portion 21. Since it is easy to make r2 longer, the upper case 13 tilts backward at a certain angle S and stands up in this state (see FIG. 6B). Therefore, it will be understood that the upper case 13 can be used for a music rest or the like.

  The upper case 13 and the lower case 12 are connected to each other in a portion other than the rear part that is hinge-coupled by a fastener 24 provided at edges 18 and 19 of the opening along the boundary line. As the fastener 24, a slide fastener including a pair of meshing teeth 24a and 24b and sliders 24c and 24d is suitable, but is not limited thereto. In the case of using a slide fastener, it is considered that some stress is applied to the portion of the inclination angle on the left and right of the boundary line. In the experiment conducted in the course of developing the present invention, the constant angle S at which the front of the upper case 13 rises with respect to the table surface 26 is suitably about 117 degrees (the numerical value of the angle S is an example) Not exact). At this time, since the tilt angle T on the left and right of the boundary line is 7 degrees, it is not a large angle and is not a stress that impairs the ease of opening and closing the fastener 24. Further, when the fastener 24 is fully opened, the sliders 24c and 24d are disposed at both ends of the hinge portion 21. At this time, the positions where the fastener meshing teeth 24a and 24b are fully opened are moved in the opening direction of the sliders 24c and 24d. If it becomes an edge part, it will act so that upper case 13 may control it from rotating back (falling down) further. This increases the stability when the upper case 13 is used as a music rest.

  The lower case 12 has a projecting partition portion 28 at the bottom of the inner surface, in which the leg portion 27 of the musical instrument main body 20 is received and fixed. It engages with the partition portion 28 and is fixed so as not to move (see FIGS. 2 and 10). The partition portion 28 in the illustrated example has a substantially conical shape, and is engaged with the leg portion 27 of the instrument body 20 at the rear portion and the left and right side portions, and spaces are provided at the rear portion and the left and right sides. It is used to store and fix the shed, which will be described later. In the front part of the musical instrument main body 20, the front part of the keyboard wind instrument itself is brought into contact with and restrained by the engagement with the high part of the front part 14 of the lower case 12, and the holding part for the performance faucet described later on the right part. 34 (see FIGS. 4, 5, 7 and 8, etc.).

  Further, the lower case 12 has a cavity 31 in which the pipe portion 29 of the table clerk 30 attached to the instrument main body 20 is disposed and a sill retainer 32, and a protruding shape to which the leg 27 of the instrument main body 20 is fixed. It has behind the partition part 28 of this. Both the void 31 and the retaining portion 32 of the shed are set between the protruding partition portion 28 and the lower portion 15 at the rear portion of the lower case 12 (see FIG. 2). The table performance pit 30 has a bent pipe portion 30a at the base and a lip portion 30b at the tip, and when connected to the instrument body 20 at the base, the pipe 29 is directed rearward to improve the storage property. . In addition, the lower case 12 has a holding portion 34 for the performance pit 33 on the right side of the projecting partition portion 28 in which the leg portion 27 of the instrument body 20 is received and fixed. The above-mentioned heel-holding portion 32 and the performance-use heel-holding portion 34 are made of cloth material or the like, and are attached to the bottom of the inner surface of the lower case 12 by means such as sewing.

  Further, the upper case 13 is provided with an inward presser convex part 35 on the inner side of the rear side of the keyboard body 20 placed on the lower case so as to be in contact with the rear upper part of the musical instrument main body 20. The wind instrument is more firmly fixed inside the case when carrying it. The presser protrusion 35 appears as a recess 35 ′ on the outer surface of the upper case 13 (see FIG. 1). In each figure, 36 indicates a hand.

  The portable storage case 10 of the present invention has the above-described configuration and action. When the table is played, when the case is opened by rotating around the hinge portion 21, the upper case 13 is supported and the back corner portion 25 is supported as a fulcrum. The portable storage case 10 functions as a music stand that uses the upper case 13 as a support for the musical score 37 (see FIG. 8B). In the state of being stored in the portable storage case 10, the keyboard wind instrument 20 is restrained by engaging the leg portions 27 of the musical instrument main body 20 with the partition portions 28 at the rear and left and right side portions. In this part, the front part 14 of the lower case 12 is brought into contact and restrained, and the holding parts 32 and 34 of the table playing mouth 30 and the standing music playing mouth 33 are also cushioned, so that they are damaged when being carried. There is no. While the conventional hard case can be used both as a music stand and is hard and heavy, the conventional soft case is soft and light, but it cannot be used as a music stand. However, according to the present invention, it is a portable storage case for a keyboard wind instrument with a semi-hard case that is lightweight and has a certain degree of rigidity. It is flexible and lightweight, and also functions as a music stand, so it maintains the advantages of the conventional case Thus, the disadvantages are eliminated and a sufficient protective effect is exhibited.
