Description

Description: TECHNICAL FIELD The present invention relates to a block type percussion instrument.

(Prior Art) Percussion instruments can be classified into two main categories: body sound instruments that produce sound by striking hard substances (wood, metal, etc.) with each other, and membrane sound instruments that produce sound by vibrating a stretched skin. is there.

Examples of body sounds and percussion instruments include classical Chinese wooden fish in the form of slit drums curved to resemble fictitious fish. The percussion instrument is cut out through a ventral slit reminiscent of a fictitious animal's mouth and banged with a stick. Thereafter, wooden fish have been used in Western orchestras in various sizes called temple blocks.

The assignee of the present application, Routine Percussion, currently sells wooden block percussion instruments of some squid design and various woodwind instruments that make the sound quality of old Chinese woodfish. They are basically shaped as elliptical rectangular blocks, characterized in that elongated slots or grooves on the front face extend substantially, but not completely, into the block. This slot functions as a sound chamber. This block is beaten by another piece of wood, such as a drumstick or mallet.

Although wooden blocks, such as those sold by Routine Percussion, produce the desired sound, this percussion instrument is relatively expensive to manufacture. Wood is a material that is difficult to process during the manufacturing process. Processing and assembling wood is a laborious task that significantly increases manufacturing costs. Moreover, as the supply of good quality wood decreases, prices continue to rise.

Further, this percussion instrument has certain inherent limitations. First
In addition, birth trees differ in densities, with grain structures that are important for sound and pitch and other physical properties differing somewhat from one to another.

Second, tears and cracks tend to occur in areas where the block is constantly beaten. As a result, the quality of the wooden blocks deteriorates significantly with use.

Third, the actual performance of wooden block percussion instruments often causes implementation difficulties. It is desirable to attach the percussion instrument to the support, but it has not been possible to attach the percussion instrument in a manner that does not impair sound quality. Generally, the method of mounting a wooden block has been to drill mounting holes in the block. The block is then positioned with a fitting having a pair of forks extending into the hole, and the block is supported tightly on the pair of forks. However, this means that the wooden block may jump or jump around when hit.
Furthermore, this design limits the number of places where blocks can be placed. The cantilever block thus mounted provides an undesirable playing surface.

Fourth, the playing surface of a wooden block is not always ideal for certain uses. Today, most users of wooden blocks are drummers. Due to the above-described problems when mounting the wooden blocks, it is difficult to tilt the wooden blocks so that the playing surface is at a comfortable angle for the drummer. Furthermore,
The playing surface of some wooden blocks requires a special mallet to produce the ideal sound. Swapping drumsticks and mallets while playing is generally not feasible for drummers, which means that even if they do not produce the best sound, they will need to It means that you have to be content with the use.

Wooden blocks were developed to take advantage of the sound quality inherent in wood. Thus, despite the inherent problems of trees, it has long been known that other substances do not make the same sound,
The only way to make a percussion instrument with the sound of a wooden block was to make it from wood.

The present invention is a block-type percussion instrument that overcomes the aforementioned limitations and problems, has a structure that can be easily and extremely rigidly mounted for use, and is inexpensive to manufacture. More specifically, the inventor of the present invention made a block type percussion instrument made of plastic by forming a block having a specific structure and configuration, thereby reproducing the sound of a wooden block percussion instrument without using wood. Find out what you can do.

A percussion instrument according to the present invention is in the form of a rectangular plastic block having a substantially rectangular block portion having a front surface, a top surface and a bottom surface, and an elongated slot on the front surface that extends substantially the width and depth of the block portion. A flange extends outwardly on either side of the block portion to the rear of the block portion and has portions used to attach percussion instruments to a support. Further, a raised ridge that functions as a striking surface extends along the upper surface adjacent to the front surface. The striking raised surface also reinforces the top vibrating surface without interfering with the vibration characteristics.

The flanges include a pair of side flanges oriented sideways, a rear flange oriented rearward, and a pair of connections between the rear flanges and both side flanges oriented approximately 45 °. It is preferably formed by a plurality of outwardly tapered flange portions having a flange portion. The flange portion is frusto-conical in cross section and terminates in a vertical outer surface, and a landing is formed on each of the side flange portion and the rear flange portion. Each landing is formed by parallel top and bottom surfaces extending inward from the outer surface and has a hole. A mounting bracket has a flat plate portion with a hole that matches the underside of the landing and matches the hole in the landing for bolting.

The ridge preferably has a curved, rearwardly extending teardrop shape in cross section to effectively transmit the striking force to the body of the percussion instrument.

The percussion instrument according to the invention is preferably made by molding. By controlling the density and composition of the material, the sound quality can be adjusted as desired. Once the desired sound quality is selected, the individual products can then be manufactured to the same sound.

The percussion instrument according to the present invention is inexpensive to manufacture and inherently durable in use, in that it can be made by molding using readily available materials. Furthermore,
This percussion instrument can be firmly mounted in various places without adversely affecting the sound quality.
Optimum sound can be obtained with drum sticks, mallets and other hitting tools.

BRIEF DESCRIPTION OF THE DRAWINGS For a better understanding of the present invention, the following detailed description of the preferred embodiments will be set forth in conjunction with the drawings.

EXAMPLE A percussion instrument according to the invention is made of a substantially rectangular block 10 made of plastic material. This block 10
It has a substantially rectangular block portion 12, and the block portion 12
Has a substantially flat front surface 14, a substantially flat top surface 16, a substantially flat bottom surface 18, and tapered flanges 20 extending from both sides of the rectangular block portion 12 and from behind. The flange is preferably frusto-conical in cross-section and terminates in a vertical surface 24 which is one-third the height of the rectangular block portion 12, as seen in FIGS. The flange has a pair of laterally extending tapered side portions 21, a rearwardly extending rear portion 22, and a pair of connecting portions 23 extending approximately 45 ° between the side and rear portions.

The rectangular block portion 12 has a slot 26 formed in the front surface 14 thereof, which extends rearward through the block portion and has a substantially rear flange, as shown by the dotted line 28.
Ends with 22. The slot 26 extends laterally over the entire block portion 12 and opposite sides of the slot
And a sound chamber is created in the block. The slot preferably has a height of approximately one quarter of the thickness of the block portion 12.

By changing the size (height) of the slot, the sound can be changed. Thus, rather than having to make a completely new mold, the sound can be changed simply by changing the mold core, thus saving a great deal on the cost of rebuilding the mold. The length, width and depth of the slots are also important in composing the selected sound,
These may be changed if desired.

Further, as shown in the drawing, the block portion 12 has an upper surface
A ridge 30 is formed extending across the front portion of the 16. The ridge has a rearward, teardrop-shaped curved surface that extends upwardly from the front surface and then becomes progressively lower as it moves rearward. The ridge forms the striking surface of a drumstick or other hitting tool. Since the hitting ridge was curved,
This allows the drumstick to hit at one point of contact, no matter what angle the block is hit.

Each of the flanges 21, 22 has a flat cutout area, or landing 32, extending inwardly from the side surface 24 and defined by a pair of horizontal upper and lower surfaces 34, 36. A hole 38 extends through each landing 32 perpendicular to the planes 34,36. As shown in FIG. 4, a bracket assembly 40 having a bracket member 42, a wing bolt 44 and a second wing bolt 46 selectively engages one of the three landings 32. The bracket assembly 40 can be used to mount percussion instruments, as described below.

The exemplary bracket 42 has a first flat plate portion 48 with a threaded hole 50. If the bracket is not thick enough to cut the screw, insert a nut (not shown)
It is preferable to weld to the bottom of the plate portion 48 so as to match with 50. Since the flat plate portion 48 is dimensioned to fit into the landing 32, the holes 50 align with the holes 38,
The bracket can be fastened with one screw without rotating with respect to the block. In this way, the butterfly bolt
Insert 44 into holes 38 and 50 and tighten it to secure the bracket to one of flanges 20 or 22. As shown, plate portion 48 is attached to lower landing surface 36 (with bolts extending from the upper landing surface through the landing holes). However, if desired, the bracket may be inverted and attached to the top surface with bolts extending from below.

The free end 52 of the bracket 42 is configured to attach to a desired base, rim, or other mounting surface. The illustrated embodiment shows a structure for mounting the bracket 42 to a common mounting device, an upright post (not shown). As shown, the free end 52 is bent into a C-shape and has a pair of aligned square cuts on the upper and lower surfaces.
54 are formed. Further, a threaded hole 56 (or nut) for receiving the bolt 46 is provided in the rear upright surface. In this way, insert the post through the resection,
Attach the bracket by clamping the bracket to the desired height using bolts 46. This configuration is merely exemplary, and may take the form of a clamp or other mounting configuration.

Block 10 (ie, block portion 12, flange 20
And ridges 30) are preferably molded as a single solid block (constituting slot 26 and hole 38). Plastic is a polyolefin material, e.g. 0.941 to 0.965
It is preferably a high density polyethylene (polymerization of ethylene) having a density in the range of gm / cc. Molding time, temperature,
Controlling the plastic substances and additives will make each product sound the same.

In the illustrated example, the block 10 has a front ridge 30 having a total width of 167 mm, a thickness (excluding the ridge 30) of 39 mm, and a height of 6 mm. Block part 12 and slot 26 are each 111m wide
m, depth 59 mm, and slot height 11 mm. Flanges 21, 23 extend outward at a distance of 28mm and have an initial thickness of 39mm
From the side to 13mm in thickness. Finally, the resection region 32 has a width of 25 mm and extends 26 mm deep. The upper part of the block is preferably thinner than the lower part. In the figure, the ratio of the thickness of the block 10 below the slot to the thickness of the block above the slot (excluding the ridge 30) is 2: 1. This is important for producing the desired desired sound.

The percussion instrument having the structure according to the present invention not only completely copies the sound of the wooden block percussion instrument, but also allows its percussion instrument to be made of plastic due to its unique structure.
For this reason, the percussion instrument lasts longer than a wooden block in that the material does not crack or crack or otherwise deteriorate in quality. At the same time, the percussion instrument, unlike the known wooden block, can be firmly mounted in various places without adversely affecting the sound quality. Because the percussion instrument can be molded, the cost and time spent in manufacturing is significantly less than in known wooden blocks. In addition, the raised front ridges provide an improved hitting surface for transmitting force to the block body so that the best sound can be obtained with a drumstick, mallet, or other hitting tool. The arrangement of the mounting holes is out of the sound emitting area.
This allows for a rigid attachment without adversely affecting the sound by vibrating.

The foregoing illustrates a preferred embodiment of the present invention. Modifications and variations of the above example will be apparent to those skilled in the art without departing from the principles of the present invention. For example, the shape of the protruding flange and the outer shape of the landing can be changed to some extent while maintaining the sound quality of the percussion instrument. In addition, the size, shape and compositional properties can be varied to produce percussion instruments of the same sound, different pitches of the same pitch, or the sound and pitch can be intentionally varied in a desired manner. All such changes and modifications are intended to be within the scope of the present invention, as set forth in the following claims.
