     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention pertains to snare drums, and more particularly, to snare drums having parallel snares uniformly mounted by parallel, closely-spaced strainers. 
     2. Description of Related Art 
     The snare drum is a well-known percussion musical instrument. FIG. 11 illustrates one example of the structure of a conventional snare drum is that disclosed in Japanese Utility Model Application, Second Publication, No. 55-19995. In FIG. 11, the snare drum 1 is viewed obliquely from below, so as to illustrate the snare mechanism thereof at the lower surface and at a portion of the side of the snare drum 1. The snare drum 1 includes a hollow cylindrical drum body 2, upper and lower drum heads 3 fitted over the openings formed at the upper and lower ends of the drum body 2. Upper and lower rims 4 are provided which engage the peripheral edge of the upper and lower drum heads 3, respectively, and which are connected together via multiple lugs 5 arranged around the outer surface of the drum body 2 and a pair of threaded nuts 6 for each lug 5. Each lug 5 is engaged with each nut of its corresponding pair of the nuts 6 by means of a thread around the lug 5 and a threaded hole in the nut 6. By means of this arrangement, each lug 5 and corresponding pair of the nuts 6 act to pull the upper and lower rims 4 toward each other, thereby applying and maintaining centrifugally directed tension to the upper and lower drum heads 3 along the peripheral edges thereof. 
     The snare drum 1 further includes snares 7 and 8 provided above the outer surface of the lower drum head 3 in FIG. 11. The snares 7 and 8 are each constructed from a snare element 9 or 10, respectively, consisting of multiple parallel strands of gut string or coiled metal wires (snappy wire), a metal retainer 11 at each end of each of the snare elements 9 or 10, and a braid 12 for each metal retainer 11 whereby each metal retainer 11 is connected with the drum body 2 via a corresponding snare strainer 13, respectively. 
     The two braids 12 at the ends of the snare 7 and those at the ends of the snare 8 each connect with the outer surface of the drum body 2 via the corresponding snare strainer 13 after first passing through a corresponding opening 4 a  for each provided in the lower rim 4. The snare strainers 13 at the ends of the snares 7 and 8 are each mounted on the side of the drum body 2 at approximately the mid-position between an adjacent pair of the lugs 5, with the lug 5 intervening between the pair of the snare strainers 13 at each side of the snare drum 1. The snare strainer 13 at one or both ends of each of the snares 7 and 8 is further provided with a rotatable lever 14 whereby the position of the snare elements 9 and 10 of the snares 7 and 8, respectively, can each be independently adjusted relative to the outer surface of the lower drum head 3, thereby making it possible to move one or both of the snare elements 9 and 10 into contact with or away from the outer surface of the lower drum head 3. By this means, it is possible to generate two or more different types of sound with the snare drum 1. 
     When the corresponding levers 14 are rotated so as to move the snare elements 9 and 10 of the snares 7 and 8 into contact with the outer surface of the lower drum head 3, the snare elements 9 and 10 vibrate in unison with the lower drum head 3 causing production of a metallic rattling sound. Conversely, when both of the levers 14 are rotated so as to move the snare elements 9 and 10 away from the outer surface of the lower drum head 3, a normal drum sound is produced. By selecting the multiple strands from which the snare elements 9 and 10 are constructed so that those of the snare element 9 and those of snare element 10 have different diameters and/or physical properties, and/or so that the number thereof is different for the snare elements 9 and 10, different timbres can be achieved depending on whether the snare element 9, the snare element 10, or both, are in contact with the outer surface of the lower drum head 3. By alternatively handling each of the levers 14 on the snare strainers 13, the position of the snare elements 9 and 10 can be independently adjusted, thus making it possible to achieve varying timbres during performance. 
     With the conventional snare drum 1 as thus described, however, because the snare strainers 13 at the ends of the snares 7 and 8 are each mounted on the side of the drum body 2 at the approximate mid-position between an adjacent pair of the lugs 5, with the lug 5 intervening between the pair of the snare strainers 13 at each side of the snare drum 1, there tends to be a significant gap between the snare elements 9 and 10. For the same reason, a player cannot simultaneously operate both of the levers 14 on both of the snare strainers 13 during performance. In addition, for the same reason, the snare elements 9 and 10 are significantly displaced from the center of the snare drum head 3. 
     Additionally, because two openings 4 a  are formed in the lower rim 4 at the approximate mid-position between the adjacent pair of the lugs 5, the flexural rigidity of the lower rim 4 at this position is not good. For this reason, an intervening lug 5 between the snare strainers 13 exerts a different force on the lower and upper rims 4 than do the other lugs 5. Accordingly, accurate adjustment of the tension applied to the drum heads 4 so as to achieve uniform tension around the snare drum 1 is very difficult. Consequently, the sound produced by each such snare drum 1 is likely to differ from that produced by other seemingly identical drums. Additionally, the clarity and sharpness of sound which is desirable for snare drums is not readily achieved. 
     Furthermore, in the conventional snare drum 1, because the snare strainers 13 are not symmetrical with respect to an intervening lug 5 as shown in FIG. 11, the snares 7 and 8 are not symmetrical with respect to an intervening diameter of the drum head 3. Additionally, the snare strainers 13 are mounted directly on the drum body 2. This places the snare strainers 13 at an angle relative to each other and to the snares 7 and 8. Consequently, the braids 12 extending from the metal retainers 11 at the ends of the snares 7 and 8 must extend at angles relative to the snares 7 and 8 and through the openings 4 a  in the rims 4 to the snare strainer 13. A further problem arises from the fact that the snares 7 and 8 are not equidistantly spaced from an intervening diameter of the lower drum head 3. Consequently, the lengths of the braids 12 are different, as are the angles of attachment to the snare strainers 13. Accordingly, because of the consequent differing spatial relation between the snare strainers 13 for the snare 7 or 8 lying closer to a diameter of the drum body 2 and those for the snare 7 or 8 lying relatively farther from the same diameter of the drum body 2, the angles formed between two of the snare strainers 13 and their corresponding snare element 9 or 10, and the angles formed between the other two snare strainers 13 and their corresponding snare element 9 or 10 are different. Consequently, the effect of operation of the levers 14 on different snare strainers 13 are likely to differ in terms of movement of the snare elements 9 and 10 away from or toward the surface of the lower drum head 3. Thus, even and reproducible adjustment of the position of the snare elements 9 and 10 is difficult to achieve. For this reason, it is difficult to insure that the snare element 9 or 10 is fully in contact with the surface of the lower drum head 3 or is fully separated from the lower drum head 3 when such is desired, making it more difficult to play this kind of snare drum 1 so as to achieve the desired sound effects. 
     FIGS. 12 and 13 illustrate one example of the structure of a conventional combination-type musical instrument which has been disclosed in U.S. Pat. No. 1,653,570. This combination-type musical instrument is made up of a percussion instrument mixed with a stringed instrument. FIG. 12 is a plan view of the mixed type of musical instrument and FIG. 13 is a cross-sectional view taken on the line A--A of FIG. 12. In FIGS. 12 and 13, the combination-type musical instrument has a shell 20, a bottom drum head 21, a top drum head 22, leg supports 23, and marginal drum head tension elements 24. Components 20 through 24, except the leg supports 23 in FIGS. 12 and 13, respectively, correspond to the drum body 1, the lower and upper drum heads 3, and components including the lugs 5 and the bolts 6 in FIG. 11. String anchor blocks 25 and 26 are mounted on diametrically opposite sides of the shell 20. A string anchor 27 is mounted on the string anchor block 25, to which each one end of a series of strings 28 through 31 is attached. Each another end of the strings 28 through 31 is connected to tuning posts 32 adjustable to be turned by keys 33 mounted in the string anchor block 26. In order to withstand the strain on the shell 20 due to the action of the strings 28 through 31, the shell 20 is braced with a strut 34 running parallel to, and midway of, the strings 28 through 31 and connected to the shell 20 at points opposite the center of the string anchor blocks 25 and 26. Bridges 35 through 38 are provided on the top drum head 22 in order that the strings 28 through 31 are supported on the top drum head 22 as a resonating body. The above-mentioned drum type of musical instrument is played by striking the strings 28 through 31 with a hammer, by picking, or by bowing according to the quantity of tone desired to be produced in the same way as a dulcimer or a cymbalon. 
     The above-mentioned conventional combination-type musical instrument is played in the same way as the dulcimer or the cymbalon of which the strings are, for example, struck with the hammer, but is not played in the same way as a snare drum in which the upper drum head is struck with drumsticks. In the above-mentioned conventional combination-type musical instrument, the tuning posts 32 are adjustable to be turned by the keys 33. However, the keys 33 are used for adjusting the tension of the strings 28 through 31 between the bridges, but not used for changing timbres during performance. Therefore, the strings 28 through 31 are not provided so that they move into contact with or away from the outer surface of the top drum head 22 during performance.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     In the following, a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an oblique view of a snare drum 50 based on the preferred embodiment of the present invention. Furthermore, the lower surface, left side and right side of the snare drum 50 are shown in FIGS. 2, 3 and 4 respectively. In these drawings, the snare drum 50 includes a hollow cylindrical drum body 51, upper and lower drum heads 52 and 53 fitted over the openings formed at the upper and lower ends of the drum body 51. Upper and lower rims 54 and 55 are provided which engage the peripheral edge of the upper and lower drum heads 52 and 53, respectively, on the upper and lower peripheral edges of the drum body 51 using lugs 56 a1  through 56 a6  and lugs 56 b1  through 56 b6 , bolts 57 a1  through 57 a6  and bolts 57 b1  through 57 b6 , and nuts 58 a1  through 58 a6  and nuts 58 b1  through 58 b6 . The lugs 56 a1  through 56 a6  and lugs 56 b1  through 56 b6  are distributed along the outer circumferential surface of the drum body 51, such that the longitudinal axis of each lug 56 a1  -56 a6  and 56 b1  -56 b6  lies approximately parallel to the longitudinal axis of the drum body 51. As can be appreciated from FIGS. 3 and 4, each lug 56 a1  through 56 a6  originates near the edge of the upper end of the drum body 51, extending centrally such that the end thereof approaches the end of a corresponding lug from among lugs 56 b1  through 56 b6  which similarly extend centrally from near the edge of the lower end of the drum body 51. The bolts 57 a1  through 57 a6  are projected from one end of a corresponding lug among the lugs 56 a1  through 56 a6  toward the edge of the upper end of the drum body 51, respectively, and are upwardly projected through holes formed in a corresponding projection among the projection 59 a1  through 59 a6  which are circumferentially spaced on the upper rim 54. The nuts 58 a1  through 58 a6  are engaged with a corresponding projected bolt among the bolts 57 a1  through 57 a6  by means of a thread formed around the bolts 57 a1  through 57 a6  and a threaded hole formed in the nuts 58 a1  through 58 a6 . The bolts 57 b1  through 57 b6  are projected from one end of a corresponding lug among the lugs 56 b1  through 56 b6  toward the edge of the lower end of the drum body 51, respectively, and are downwardly projected through holes formed in a corresponding projection among the projection 59 b1  through 59 b6  which are circumferentially spaced on the lower rim 55. The nuts 58 b1  through 58 b6  are engaged with a corresponding projected bolt among the bolts 57 b1  through 57 b6  by means of a thread formed around the bolts 57 b1  through 57 b6  and a threaded hole formed in the nuts 58 b1  through 58 b6 . By means of this arrangement, each lug 56 a1  -56 a6  and 56 b1  -56 b6  and corresponding of the bolts 57 a1  -57 a6  and 57 b1  -57 b6  6 and corresponding of the nuts 58 a1  -58 a6  and 58 b1  -58 b6  act to pull the upper and lower rims 54 and 55 toward one another, thereby applying and maintaining centrifugally directed tension to the upper and lower drum heads 52 and 53 along the peripheral edges thereof. 
     The snare drum 50 further includes snares 60 and 61 which run across the lower end of the drum 50 in an approximately parallel relationship with respect to one another and in an approximately parallel relationship with a diameter of the snare drum 50, and in proximity to the outer surface of the lower drum head 53. The snares 60 and 61 are each constructed from a snare element 62 or 63, respectively, consisting of multiple parallel strands of gut string and the like, a metal retainer 64 at each end of each of the snare element 62 or 63, and a braid 65 for each metal retainer 64 whereby each metal retainer 64 is connected with drum body 51 via a corresponding snare strainer 66 or 67, respectively. 
     The two braids 65 at the ends of the snare 60 and those at the ends of the snare 61 each connect with the outer surface of the drum body 51 via a corresponding snare strainer 66 or 67 after first passing through a corresponding opening 55 a  for each provided in the lower rim 55. 
     At each of two approximately diametrically opposing positions along the outer circumferential surface of the drum body 51, the pair of the snare strainers 66 and 67 are provided in an orientation approximately parallel to that of lugs 56 a1  -56 a6  and 56 b1  -56 b6 . As is best shown in FIGS. 3 and 4, opposing lugs 56 a1  and 56 b1  lie between the pair of the snare strainers 66 and 67 at one side of the drum body 51, and opposing lugs 56 a4  and 56 b4  lie between the pair of the snare strainers 66 and 67 at the opposite side of the drum body 51. As shown in FIGS. 2 and 3, the braid 65 which is attached to the left end of the snare 60 and the braid 65 which is attached to the left end of the snare 61 each connect with lever sides 66 a  and 67 a  of the snare strainers 66 and 66, respectively. Similarly, and as is shown in FIGS. 2 and 4, the braid 65 which is attached to the right end of the snare 60 and the braid 65 which is attached to the right end of the snare 61 each connect with butt sides 66 b  and 67 b  of the snare strainers 66 and 67, respectively. 
     As is shown in FIGS. 3 through 8, bases 68 are provided, by means of which the snare strainers 66 and 67 are mounted on the outer surface of the drum body 51 so as to lie parallel to a diameter of the lower drum head 53 and to be in a substantially parallel relationship to one another. In FIGS. 5 and 6, the upper rim 54, the lugs 56 a1 , 56 a4 , 56 b1 , and 56 b4 , the bolts 57 a1 , 57 a4 , 57 b1 , and 57 b4 , and the nuts 58 a1 , 58 a4 , 58 b1 , and 58 b4  are not drawn so as to clearly represent the connected relation between the drum body 51 and the base 68. In FIGS. 7 and 8, the lugs 56 a1 , 56 a4 , 56 b1 , and 56 b4 , the bolts 57 a1 , 57 a4 , 57 b1 , and 57 b4 , and the nuts 58 a1 , 58 a4 , 58 b1 , and 58 b4  are not drawn for the same reason as was the case in FIGS. 5 and 6. Each part of the snare strainers 66 and 67 is inserted in each recess formed on each one side 68 a  of the bases 68. Each of the other sides 68 b  of the bases 68 are formed so that almost all of the surfaces of the other sides 68 b  of the bases 68 can be contacted with the outer circumferential surface of the drum body 51. The bases 68 are connected to the drum body 51 by means of fitting members 69 and bolts 70. Each one side 69 a  of the fitting members 69 are formed so that almost all of the surfaces of each one side 69 a  of the fitting members 69 can be contacted with an inner circumferential surface of the drum body 51. The bolts 70 are engaged with the bases 68 through each hole formed in the drum body 51 and the fitting members 69 by means of a thread formed around the bolts 70 and a threaded hole in the bases 68. Each surface of one side 68 b  of the bases 68 and one side 69 a  of the fitting members 69 is flat and is parallel to one another, and is orthogonal to the diameter of the drum body 51. 
     In FIGS. 1, 3, 5, 7, 9, and 10, the lever sides 66 a  and 67 a  of the snare strainers 66 and 67 are provided with rotatable levers 71 a  and 71 b  whereby the position of the snare elements 62 and 63 of the snares 60 and 61, respectively, can each be independently adjusted relative to the outer surface of the lower drum head 53, thereby making it possible to move one or both of the snare elements 62 and 63 into contact with, or moved away from, the outer surface of the lower drum head 53. In this way, it is possible to generate two or more different types of sound with the snare drum 50. In FIGS. 3, 7, 9, and 10, levers 71 a  and 71 b  are rotatably fixed on strainer bodies 72 a  and 72 b  by means of screws 73 a  and 73 b  as a shaft. At one side of the approximate mid-position of the levers 71 a  and 71 b , rollers 74 a  and 74 b  are rotatably secured by screws 75 a  and 75 b  inserted from the other side of the lever 71 a  and 71 b  and move in tracks 77 a  and 77 b  formed in sliders 76 a  and 76 b  with their own rotation by rotating the levers 71 a  and 71 b . Accordingly, the sliders 76 a  and 76 b  are vertically moved by rotating the levers 71 a  and 71 b . Furthermore, in FIGS. 3, 5, 7, 9, and 10, snare fitting members 78 a  and 78 b  are secured at each lower part of the sliders 76 a  and 76 b  by means of adjustment bolts 79 a  and 79 b  and a threaded hole formed in the snare fitting members 78 a  and 78 b . Each of the braids 65 is attached at each lower part of the snare fitting members 78 a  and 78 b  by being pinched between the snare fitting members 78 a  and 78 b  and plates 80 a  and 80 b  using bolts 81 a  and 81 b . By rotating the adjustment bolts 79 a  and 79 b , the position of the snare fitting members 78 a  and 78 b  can be adjusted upward and downward, thereby adjusting the tension applied to the snares 60 and 61. In FIGS. 4, 6, and 8, at the butt sides 66 b  and 67 b  of the snare strainers 66 and 67 are provided snare bodies 72 c  and 72 d , sliders 76 c  and 76 d , adjustment bolts 79 c  and 79 d , plates 80 c  and 80 d , and bolts 81 c  and 81 d , which correspond to and have the same structures and the same functions as the strainer bodies 72 a  and 72 b , the sliders 76 a  and 76 b , the adjustment bolts 79 a  and 79 b , the plates 80 a  and 80 b , and the bolts 81 a  and 81 b  of the lever sides 66 a  and 67 a  of the snare strainers 66 and 67, respectively. Furthermore, the sliders 76 c  and 76 d  also have structures and functions which the snare fitting members of the lever sides 66 a  and 67 a  have, respectively. 
     In FIGS. 3, 4, 7, and 8, the snare guides 82 are inserted between bases 68 and the strainer bodies 72 a  through 72 d  so as to maintain the snares 60 and 61 in a parallel relationship with the diameter of the lower drum head 53. The position of the snare guides 82 is not affected by upward or downward movement of the snare strainers 66 and 67 effected by the adjustment bolts 79 a  through 79 d . The snare guides 82 are provided with smooth edges 82 a  made of Teflon (polytetrafluoroethylene) or the like over which corresponding braids 65 run, and with braid retainers 82 b  to prevent the braids 65 from passing beyond their corresponding snare guides 82 when the levers 71 a  and 71 b  are operated so as to move the snares 60 and 61 away from the lower drum head 53. 
     With the snare drum 50 of the embodiment of the present invention as thus described, when a performer moves the lever 71 a  of the snare strainer 67 from the position indicated by the broken line in FIG. 3 to that indicated by the solid line, the lever side 66 a  of the snare strainer 66 moves upward, bringing the snare element 62 into full contact with the surface of the lower drum head 53. When the performer, for example, moves the lever 71 b  of the snare strainer 67 from the position indicated by the solid line in FIG. 3 to that indicated by the broken line, the lever side 67 a  of the snare strainer 67 moves downward, moving the snare element 63 completely away from the surface of the lower drum head 53, the corresponding braid retainers 82 b  preventing the braid 65 from continuing beyond the snare guide 82. 
     Because the snares 60 and 61 of the snare drum 50 of this embodiment are In close proximity, the parallel relationship to one another in proximity to and parallel with the diameter of the lower drum head 53, simultaneous or independent operation of each of the levers 71 a  and 71 b  of corresponding snare strainers 66 and 67, respectively, can rapidly and easily be carried out during the course of a performance. By providing the snares 60 and 61 which apply differing timbre characteristics when in contact with the lower drum head 53, simple manipulation of the levers 71 a  and 71 b  during a performance permits generation of drum sound having multiple freely selectable timbres. 
     Furthermore, the close proximity of the snare strainers 66 and 67 to the intervening lugs 56 on each side permits the openings 55 a  in the lower rim 55 to similarly lie in close proximity to the intervening lugs 56, thereby enhancing mechanical strength of the lower rim 55, in this way permitting finely controlled adjustment of the tension on the bolts 58 around the lower rim 55 so as to attain highly uniform tension applied to the upper and lower drum heads 52 and 53 around their periphery. 
     Provision of the base 68 allows the snare strainers 66 and 67 to have a smaller total height along the surface of the drum body 51. When the levers 71 a  and 71 b  are both rotated in toward the lugs 56 a1  and 56 b1 , the snare elements 62 and 63 move smoothly into full contact with the lower drum head 53, whereas when the levers 71 a  and 71 b  are both rotated outward, the snare elements 62 and 63 both move smoothly and completely away from the surface of the lower drum head 53. For these reasons, simple operation of the snares 60 and 61 is easily conducted during a performance using only one hand. 
     In the present embodiment, the snare strainers 66 and 67 are joined on each side by means of the previously described base 68. The base 68 is not a limiting feature of the present invention, and can be dispensed with as long as the strainers 66 and 67 are mounted in a close parallel relationship with the diameter of the lower drum head 53. It should be noted, however, that inclusion of the bases 68 provides added stability, and also simplifies manufacture of this type of snare drum.
