  However, in the method in which a wire is stretched between the organ and the floor via a dedicated bracket and fixed with a turnbuckle, or the method in which the back of the organ and the column are connected and fixed with a bracket, the organ is fixed to the floor or column once. If it can be moved, there is a problem that it cannot be easily moved, and even if it can be moved, there is a problem in that the metal remains on the floor and pillars, which is dangerous. In addition, a device that prevents fall by installing a fall prevention device made of a metal frame on the back of an upright piano can prevent fall to the back side, but cannot prevent fall to the front side. was there. Furthermore, the method of preventing falls only during storage requires that children and students stay around the organ during a music lesson, but this does not prevent falls when necessary. was there.

  The present invention has been made in order to solve the above-mentioned problems, and it is not necessary to attach a bracket to a floor or a pillar, and it is easy to move, and an earthquake has occurred in any state during use and storage. An object of the present invention is to provide an organ tipping prevention device that can prevent tipping over to the front side and the rear side even in such a case.

  In order to solve the above-mentioned problem, in the organ tipping prevention device of the present invention, a flat steel material is bent at a right angle so as to form an L-shape at a short side inner surface front end and a long side inner surface front end. The short side outer surface of the frame is brought into contact with the floor, and the long side outer surface is fixed to the left and right ends of the rear surface of the organ by fixing fittings. Further, in order to lower the center of gravity of the organ provided with the above-mentioned organ overturn preventing device, a prismatic or cylindrical steel material is provided as a weight on the inner surfaces of right and left frames at right angles.

  If the organ fall prevention device of the present invention is arranged in advance on the back of the organ used for music classes such as kindergartens, nursery schools and elementary schools, it will prevent falls on both the front side and the back side when an earthquake occurs It has a tremendous effect that it can be done. In addition, there is no need to attach a metal fitting to the floor or the pillar, so that the movement can be easily performed.

  The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which the organ overturn prevention device of the present invention is attached to an organ. FIG. 2 is a side view showing a state where the organ tipping prevention device of the present invention is attached to the organ, and FIG. 3 is a front view showing a state where the organ tipping prevention device of the present invention is attached to the organ.

  As shown in the figure, an organ tip-over prevention device 1 of the present invention reinforces a flat steel material bent at a right angle so as to form an L-shape at a short side inner surface front end and a long side inner surface front end. A shaft 5 is inclined, and the outer surface on the short side of the frame 3 is brought into contact with the floor 18, and the outer surface on the long side is engaged and fixed to the left and right ends on the back side of the organ 2 by fixing brackets 8. The means for fixing the shaft 5 to the frame 3 is preferably welding. In addition, the shape of the shaft 5 is preferably a round metal pipe or a metal rod in consideration of safety at the time of contact with a child or a student, but a round metal pipe or a metal rod with a rounded corner is preferable. It may be used and is not particularly limited.

  Next, in order to increase the stability by lowering the center of gravity of the organ 2 on which the above-mentioned organ tipping prevention device 1 is disposed, a rectangular or cylindrical steel material as the weight 4 is installed on the inner surface of the right and left frames 3 at right angles. As a means for fixing the weight 4 to the frame 3, screwing is suitable. Although the weight 4 is illustrated as a prismatic steel material in FIGS. 1 to 3, a cylindrical steel material may be used as long as it is considered that screwing can be securely performed.

  FIGS. 4A and 4B are detailed views of the fixing hardware of the organ overturn prevention device of the present invention. FIG. 4A is a front view, FIG. 4B is a side view, and FIG. FIG. 4 is a front view of a state in which a fixture of the tool is fixed to the organ.

  As shown in the figure, a fixing bracket 8 has a long hole 11 for sliding a fastening position with a bolt 14 on a main body 9 made of a flat steel material and a head for the bolt 14 for hiding the main body 9 in the main body 9. And a side plate 10 in which a plurality of screw holes 13 are drilled at one end is fixed by welding or the like. Then, the fixing brackets 8 are symmetrically engaged with holes 15 formed in two upper and lower portions on the long side of the left and right frames 3 so as to sandwich the side of the rear surface of the organ 2.

  An embodiment of the arrangement of the organ overturn prevention device 1 of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 3, first, a fixing bracket 8 is fixed to a side portion on a rear surface of the organ 2 in order to dispose the organ overturn prevention device 1 of the present invention on the organ 2. In this case, the elongate hole 11 of the fixture 8 communicates with the hole 15 of the frame 3 through the bolt 14 and is temporarily fixed with the nut 16. In addition, the weight 4 is mounted on the frame 3 in advance and fixed. Then, the main body 9 and the side plate 10 of the fixing bracket 8 are slid so as to be in close contact with the side of the rear surface of the organ 2, and a screw 17 is screwed into the screw hole 13 of the side plate 10 from the rear side surface of the organ 2. I do. After that, the arrangement state of the frame 3 is adjusted and the nut 16 is tightened, so that the organ 2 and the organ tip-over prevention device 1 are fixed integrally. In addition, the shape of the nut 16 is preferably a cap nut as illustrated in consideration of safety at the time of contact of a child or a student, but is not particularly limited.

  As described above, by disposing the organ overturn prevention device 1 on the back surface of the organ 2, the bottom area of the organ 2 is substantially increased. For example, when the length of the short side of the frame 3 is 300 mm, the depth of the organ 2 is 420 mm, and the width is 950 mm, the bottom area is increased by about 70% by disposing the organ overturn prevention device 1. Become. Further, by fixing the weight 4, the own weight of the organ tipping-over prevention device 1 becomes about 20 kg, the center of gravity is lowered, and the stability is further improved. For this reason, even when an earthquake with a seismic intensity of 6 or more occurs, it is possible to prevent a fall to the front side and the back side. When the organ 2 does not need to be moved and may be fixed to the floor 18 at all times, or when further stability is required in the event of an earthquake, two positions may be provided on the short side of the frame 3. A hole 19 may be formed, and a screw (not shown) may be screwed to the floor 18 from the hole 19.

  Further, if the receiving member 7 is disposed at the upper end of the long side of the left and right frames 3 and the shaft 6 is fixed to the receiving member 7, a basket is hung on the shaft 6 and a musical score or the like is inserted. Or, it is possible to hang an S-shaped fitting to suspend small articles or the like.

  Although the organ tipping-over prevention device 1 shown in FIGS. 1 to 3 is drawn as having a generally used width of the organ 2 of about 800 to 950 mm, the wide type of the organ 2 having a width of about 1200 mm is used. In this case, the weight 4 and the shaft 6 can be fixed by changing the length to about 1000 mm. In this case, since the lengths of the weight 4 and the shaft 6 are simply extended in accordance with the extension of the width of the organ 2, the fixing brackets 8 engaged at the upper and lower two places on the long side of the frame 3 are attached to the rear side of the organ 2. The fixing method is the same.

  The organ fall prevention device 1 according to the present invention is designed to prevent the fall of the organ 2 in the event of an earthquake. However, not only the organ 2 but also furniture such as a bookshelf and a TV stand, a product case, etc. It can also be used to prevent fallen boxes.
