Description

Technical Field

[0001] This disclosure relates to a traveling frame. Background Technology

[0002] Percussionists playing instruments such as marching drums support their instruments in front of their bodies while playing. Therefore, percussionists wear marching back frames as a means of mounting their instruments to their bodies.

[0003] For example, the travel frame disclosed in U.S. Patent No. 7,671,261 includes: a back panel that covers the performer's abdomen; and a frame body that hangs on the shoulders and is fixed to the back panel. The frame body is composed of a generally U-shaped rod-like member extending from the back, through the shoulders, and to the abdomen. Cushioning material is provided in the portions of the frame body that contact the back and shoulders, and in the portions of the back panel that contact the abdomen, to reduce the load from the travel frame on the performer.

[0004] Percussion players come in a wide variety of body shapes. Therefore, depending on the player's body shape, the load from the travel frame is sometimes concentrated on specific parts of the body. However, as disclosed in U.S. Patent No. 7,671,261, a travel frame consisting only of cushioning material is insufficient to adequately reduce the load on the player. Therefore, as disclosed in U.S. Patent Nos. 6,323,407 and 7,554,024, the proposal proposes a travel frame with an adjustable body shape.

[0005] The travel backpack disclosed in U.S. Patent No. 6,323,407 includes a belly panel covering the performer's abdomen, straps that hang from the back and shoulders, and a pair of rod-shaped members connecting the belly panel and the straps. The pair of rod-shaped members are rotatably connected to the front ends of both sides of the straps. Thus, the travel backpack can adjust the shape of its main body at a point corresponding to the performer's chest.

[0006] The travel back frame disclosed in U.S. Patent No. 7,554,024 includes a belly plate that covers the performer's abdomen and has an abdominal cushioning component, and a frame that hangs on the back and shoulders and has shoulder cushioning components. Furthermore, the travel back frame includes a plate fixed to the upper part of the belly plate and a pair of rod-shaped members connecting the plate and the frame. The pair of rod-shaped members are rotatably connected to the upper ends of both sides of the plate and the front ends of both sides of the frame, respectively. Thus, the travel back frame allows for adjustment of the shape of the main body of the back frame at two locations corresponding to the performer's chest and shoulders. Summary of the Invention

[0007] In marching bands, musicians not only stand and play wind and percussion instruments, but sometimes also play while walking or running. In particular, percussionists bear the load not only from the instruments themselves, but also from the weight of the marching frame itself, affecting their backs, shoulders, and abdomen. Therefore, playing percussion while wearing the marching frame is a considerable burden for the musicians. Consequently, there is a need to further reduce the burden on the musicians when designing marching frames.

[0008] The problem that the invention aims to solve

[0009] The purpose of this disclosure is to provide a travel frame that can reduce the burden on the performer from the travel frame.

[0010] Solution for solving the problem

[0011] One aspect of the present disclosure is a travel frame worn on the body of a performer and supporting an instrument in front of the body. The travel frame includes: a belly board that covers the performer's abdomen and has an abdomen pad in the portion that contacts the abdomen; and a frame body that hangs on the performer's shoulders and is fixed to the belly board, having shoulder pads in the portion that contacts the shoulders. The frame body is composed of rod-shaped members having a pair of forward extensions extending from the shoulders toward the abdomen and is configured to adjust the position of the abdomen pad in the fore-aft direction.

[0012] Another aspect of this disclosure involves a travel frame worn on the performer's body and supporting a drum in front of the body. In this travel frame, the drum has a cylindrical body and a drumhead mounted at an open end of the body. The drum is configured such that the axis of the body is horizontal, and is supported by the travel frame at a first position and a second position below the first position on the drum body. The travel frame includes: a belly board that covers the performer's abdomen and has an abdominal pad at the portion in contact with the abdomen; a frame body that hangs on the performer's shoulders and is fixed to the belly board; an upper support member that supports the drum at the first position on the drum body; and a lower support member that supports the drum at the second position on the drum body. The frame body is composed of a rod-shaped member having a pair of forward extensions extending from the shoulders toward the abdomen, the upper support member being slidably fitted to the pair of forward extensions.

[0023] (First Embodiment)

[0024] The following is for reference Figures 1-6 The first embodiment of the traveling frame 10 of the present invention will be described.

[0025] like Figure 1 and Figure 2 As shown, the travel frame 10 includes a web 12, a frame body 13, an instrument support member 14, and a fixing assembly 15. The travel frame 10 is used as a device worn on the body of a performer to support percussion instruments such as a marching snare drum in front of the body. The travel frame 10 is constructed by assembling the web 12, frame body 13, and instrument support member 14 into a single unit using the fixing assembly 15.

[0026] The belly plate 12 forms the part that covers the performer's abdomen. The belly plate 12 is made of a rigid material such as metal or resin. A through hole 12a for assembly with the back frame body 13 is formed in the center of the belly plate 12. The through hole 12a extends linearly from near the upper end of the belly plate 12 to near the lower end. The part of the belly plate 12 that contacts the abdomen has an abdomen pad 21. A plate-shaped cushioning element is used in the abdomen pad 21 to reduce the load, impact, and other burdens on the performer from the traveling back frame 10. The abdomen pad 21 is approximately the same shape as the belly plate 12.

[0027] The main body 13 of the back frame hangs on the performer's shoulders and forms the upper part of the traveling back frame 10 above the belly plate 12. The main body 13 of the back frame is fixed to the side of the belly plate 12 opposite to the belly pad 21, i.e., the center of the front surface of the belly plate 12, by a fixing component 15. The main body 13 of the back frame has a skeleton part 30 composed of multiple rod-shaped members and a cushioning piece 40 that covers the back from both shoulders. The cushioning piece 40 is generally U-shaped when viewed from above. The part of the cushioning piece 40 that contacts the shoulders is the shoulder pad 38, and the part that contacts the back is the back pad 39.

[0028] The frame portion 30 includes a pair of first rod-shaped members 31 on the left and right, a second rod-shaped member 32 connected to the front end of the first rod-shaped member 31, and a third rod-shaped member 33 connected to the rear end of the first rod-shaped member 31. The cushioning member 40 is rotatably mounted relative to the rod-shaped members constituting the frame portion 30 about the axis of the rod-shaped members. Here, in the cushioning member 40, the shoulder pad 38 is rotatable relative to the first rod-shaped member 31, and the back pad 39 is rotatable relative to the third rod-shaped member 33.

[0029] In addition, the frame portion 30 includes a pair of left and right main body adjustment mechanisms 34 and a pair of left and right rear back adjustment mechanisms 35. The main body adjustment mechanisms 34 are located at the connection between the first rod-shaped member 31 and the second rod-shaped member 32. When viewed from the side, the two main body adjustment mechanisms 34 are respectively positioned on the same axis. The rear back adjustment mechanisms 35 are located at the connection between the first rod-shaped member 31 and the third rod-shaped member 33. When viewed from the side, the two rear back adjustment mechanisms 35 are respectively positioned on the same axis.

[0030] The first to third rod-shaped components 31 to 33 are made of rigid materials such as metal and resin, specifically, metal tubes and resin tubes. The first rod-shaped component 31 forms the part hanging on both shoulders, that is, the upper torso 13a, located above the main adjustment mechanism 34. The first rod-shaped component 31 curves gently along the shape of the shoulders. The second rod-shaped component 32 forms the part positioned in front of the body, that is, the lower torso 13b, located below the main adjustment mechanism 34. The second rod-shaped component 32 is longitudinally elongated and U-shaped. The second rod-shaped component 32 has a pair of upper ends 32a that are symmetrically bent into an S-shape. The third rod-shaped component 33 forms the part hanging on the performer's back, that is, the back 13c, located behind the back adjustment mechanism 35. The third rod-shaped component 33 is laterally elongated and U-shaped.

[0031] The skeleton section 30 is generally ring-shaped. A main body adjustment mechanism 34 is provided on each of the two pairs of front extensions extending from the shoulders toward the abdomen at the front of the skeleton section 30. Each front extension is composed of a portion extending forward of the first rod-shaped member 31 and a second rod-shaped member 32. A back adjustment mechanism 35 is provided on each of the two pairs of rear extensions extending from the shoulders toward the back at the rear of the skeleton section 30. Each rear extension is composed of a portion extending backward of the first rod-shaped member 31 and a third rod-shaped member 33.

[0032] The main adjustment mechanism 34 rotatably connects the lower torso 13b to the upper torso 13a by rotatably connecting the first rod-shaped member 31 and the second rod-shaped member 32. The back frame main body 13, by having the main adjustment mechanism 34, is configured to adjust the position of the lower torso 13b relative to the upper torso 13a. That is, the back frame main body 13, by having the main adjustment mechanism 34, is configured to adjust the front-to-back position of the abdominal pad 21 while keeping the shoulder pads 38 fixed in their original position.

[0033] The backrest adjustment mechanism 35 rotatably connects the first rod-shaped member 31 and the third rod-shaped member 33, thereby rotatably connecting the backrest 13c to the upper torso 13a. The backrest main body 13, by having the backrest adjustment mechanism 35, is configured to adjust the position of the backrest 13c relative to the upper torso 13a. That is, the backrest main body 13, by having the backrest adjustment mechanism 35, is configured to adjust the front-to-back position of the backrest 13c while keeping the shoulder pads 38 fixed in their original positions.

[0034] like Figure 2 and Figure 3As shown, when viewed from the front and from above, the main body adjustment mechanism 34 connects the first rod-shaped member 31 and the second rod-shaped member 32 in a state where they are arranged on the same straight line. The main body adjustment mechanism 34 includes a first cylindrical member 41 mounted on the front end of the first rod-shaped member 31 and a second cylindrical member 42 mounted on the upper end 32a of the second rod-shaped member 32. In addition, the main body adjustment mechanism 34 includes a multi-plate clutch 43 consisting of six friction plates 46, and bolts 44 and nuts 45. The rear back adjustment mechanism 35 has the same structure as the main body adjustment mechanism 34, except that it adjusts the rotational position of the third rod-shaped member 33 relative to the first rod-shaped member 31. Therefore, detailed descriptions of the parts of the rear back adjustment mechanism 35 that are the same as those in the main body adjustment mechanism 34 are omitted.

[0035] like Figure 3 , Figure 4A as well as Figure 4B As shown, the first cylindrical member 41 has a first fixing portion 41a fixed to the first rod-shaped member 31 and a first connecting portion 41b connected to the second cylindrical member 42. The first fixing portion 41a has fixing holes 41c and 41d. The first rod-shaped member 31 is fixed to the fixing hole 41c, and the multi-plate clutch 43 is fixed to the fixing hole 41d. The two fixing holes 41c and 41d are coaxially arranged and interconnected. The first connecting portion 41b has a through hole 41e through which a bolt 44 is inserted. Additionally, a recess 41f for inserting a nut 45 is formed on the outer surface of the first connecting portion 41b. The through hole 41e and the recess 41f are coaxially arranged and interconnected.

[0036] The second cylindrical member 42 has a second fixing portion 42a fixed to the second rod-shaped member 32 and a second connecting portion 42b connected to the first cylindrical member 41. The second fixing portion 42a has fixing holes 42c and 42d. The second rod-shaped member 32 is fixed to fixing hole 42c, and the multi-plate clutch 43 is fixed to fixing hole 42d. The two fixing holes 42c and 42d are coaxially arranged and interconnected. The second connecting portion 42b has a through hole 42e for a bolt 44 to be inserted. Furthermore, a recess 42f is formed on the outer surface of the second connecting portion 42b, and the head of the bolt 44 is disposed in the recess 42f. The through hole 42e and the recess 42f are coaxially arranged and interconnected.

[0037] Each friction plate 46 has a circular disc portion 46a and a rectangular fixing plate portion 46b. A through hole 46c for a bolt 44 is formed in the center of the disc portion 46a. The fixing plate portion 46b extends radially outward from the outer periphery of the disc portion 46a. Each friction plate 46 is disposed between the first connecting portion 41b and the second connecting portion 42b. Each friction plate 46 is arranged in a state of overlapping in the rotational axis of the second rod-shaped member 32 relative to the first rod-shaped member 31. Of the six friction plates 46, from... Figure 3 The fixing plate portion 46b of the odd-numbered friction plate 46 starting from the left is fixed to the fixing hole 41d of the first connecting portion 41b, and the fixing plate portion 46b of the even-numbered friction plate 46 starting from the left is fixed to the fixing hole 42d of the second connecting portion 42b.

[0038] Bolt 44 is inserted through the through holes 42e, 46c, and 41e of the second connecting part 42b, friction plate 46, and first connecting part 41b, and is screwed into nut 45. By tightening or loosening bolt 44, the force holding each friction plate 46 by the first connecting part 41b and second connecting part 42b is strengthened or weakened. As a result, the position of the second rod-shaped member 32 relative to the first rod-shaped member 31 is fixed, or the fixation of the second rod-shaped member 32 relative to the first rod-shaped member 31 is released.

[0039] like Figure 1 and Figure 2 As shown, the instrument support member 14 includes a pair of support rods 50, a pair of hooks 51 fixed to the top ends of the two support rods 50, and a bridging member 52 connected to the two hooks 51. Each support rod 50 is formed in a generally J-shape with its top end facing upward. A percussion instrument supported by the travel frame 10 is mounted on the upper surface of each hook 51. The instrument support member 14 is configured such that by connecting the percussion instrument to the two hooks 51 and fixing the two support rods 50 to the frame body 13, the percussion instrument is supported in front of the player's body. In addition, the instrument support member 14 is directly mounted to the lower torso 13b of the frame body 13 by fixing the support rods 50 to the fixing assembly 15.

[0040] The fixing assembly 15 includes a generally rectangular fixing base 55 and a first fixing member 56 fixed to the center of the front surface of the fixing base 55. Additionally, the fixing assembly 15 includes a pair of second fixing members 57 fixed to both ends of the back of the fixing base 55, and a third fixing member 58 fixed to the fixing base 55 from the back side of the web plate 12. The fixing assembly 15 is a component assembly composed of multiple parts, configured to fix the instrument support member 14 to the back frame body 13, and to fix the back frame body 13 to the web plate 12.

[0041] like Figure 2 and Figure 5As shown, a pair of vertical insertion holes 55a are formed in the center of the fixed base 55. Additionally, a pair of left and right back frame main body fixing recesses 55b are formed near the center of the front surface of the fixed base 55. The two back frame main body fixing recesses 55b are arranged parallel to each other and extend vertically. Insertion holes 55c are formed at both ends of the fixed base 55. Furthermore, a pair of left and right support rod fixing recesses 55d are formed at both ends of the back surface of the fixed base 55. The two support rod fixing recesses 55d are arranged parallel to each other and extend vertically.

[0042] A pair of upper and lower through holes 56a are formed in the center of the first fixing member 56. Curved recesses 56b are formed at both ends of the first fixing member 56. A pair of upper and lower through holes 58a are formed in the center of the third fixing member 58. The first fixing member 56, the fixing base 55, the web plate 12, and the third fixing member 58 are arranged so that the through holes 56a, 55a, 12a, and 58a are arranged coaxially. In this state, two bolts 61 insert through the through holes 56a, 55a, 12a, and 58a, and are screwed into the back side of the third fixing member 58 with a nut 62. Thus, the first fixing member 56 is fixed to the fixing base 55, and the fixing base 55 and the third fixing member 58 are fixed to the web plate 12. In this state, a space is formed between the back frame body fixing recess 55b and the curved recess 56b for the second rod-shaped member 32 of the back frame body 13.

[0043] The second fastener 57 has a through hole 57a through which a bolt 63 is inserted. The second fastener 57 has a curved recess 57b on the side opposite to the through hole 57a. The second fastener 57 and the fixing base 55 are arranged coaxially with the through holes 57a and 55c respectively. In this state, the bolt 63 inserts through the through holes 57a and 55c and engages with the nut 64 on the back side of the second fastener 57. Thus, the second fastener 57 is fixed to the fixing base 55. In this state, a space is formed between the support rod fixing recess 55d and the curved recess 57b for the support rod 50 of the musical instrument support member 14.

[0044] Next, refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 The function of the traveling frame 10 will be explained.

[0045] like Figure 1 and Figure 6As shown, the travel back frame 10 has a main body adjustment mechanism 34 at the connection points of a pair of front extensions extending from the player's shoulders toward the abdomen, namely the two first rod-shaped members 31 and the second rod-shaped member 32. Additionally, the travel back frame 10 has a rear back adjustment mechanism 35 at the connection points of a pair of rear extensions extending from the shoulders toward the back, namely the two first rod-shaped members 31 and the third rod-shaped member 33. The player adjusts the shape of the back frame main body 13 or the vertical position of the belly board 12 according to their body shape, following the steps described below. Furthermore, the player adjusts the vertical position of the instrument support member 14 to position the percussion instrument for easy playing.

[0046] like Figure 1 , Figure 3 as well as Figure 6 As shown, in order to adjust the shape of the back frame body 13, the bolts 44 of the left and right pair of main body adjustment mechanisms 34 are loosened respectively. This reduces the force holding the friction plate 46 between the first connecting part 41b and the second connecting part 42b in the main body adjustment mechanism 34. Consequently, the disc portions 46a of the friction plate 46 can slide relative to each other around the axis of the bolts 44. Therefore, the second rod-shaped member 32 can rotate relative to the first rod-shaped member 31, allowing adjustment of the rotational position of the lower torso 13b relative to the upper torso 13a.

[0047] In the pair of left and right back adjustment mechanisms 35, the same operation as described above is performed so that the third rod-shaped member 33 can rotate relative to the first rod-shaped member 31, thereby adjusting the rotational position of the back 13c relative to the upper torso 13a. For example, when a large-bodied performer wears the travel frame 10, the shape of the frame body 13 is adjusted as follows. For example, as... Figure 6 As shown by the solid line and double-dotted line, adjustment is made by decreasing the angles of the first rod-shaped member 31 and the second rod-shaped member 32 through the two main body adjustment mechanisms 34. Additionally, adjustment is made by increasing the angles of the first rod-shaped member 31 and the third rod-shaped member 33 through the two rear back adjustment mechanisms 35.

[0048] After adjusting the shape of the back frame body 13, the bolts 44 of the two main body adjustment mechanisms 34 are tightened respectively. This strengthens the force holding each friction plate 46 by the first connecting part 41b and the second connecting part 42b in the main body adjustment mechanism 34. Consequently, the disc portions 46a of the friction plates 46 cannot slide relative to each other around the axis of the bolts 44. Therefore, the rotational position of the second rod-shaped member 32 relative to the first rod-shaped member 31 is fixed, and the rotational position of the lower torso 13b relative to the upper torso 13a is fixed. The same operation is performed in the rear back adjustment mechanism 35, thereby fixing the rotational position of the third rod-shaped member 33 relative to the first rod-shaped member 31, and fixing the rotational position of the rear back 13c relative to the upper torso 13a. Next, the vertical positions of the belly plate 12 and the instrument support member 14 are adjusted respectively.

[0049] like Figure 1 and Figure 5 As shown, the upper and lower bolts 61 of the fixing assembly 15 are loosened. This reduces the force holding the second rod-shaped member 32 by the fixing base 55 and the first fixing member 56, and also reduces the force holding the web plate 12 by the fixing base 55 and the third fixing member 58. In this case, the pressure of the first fixing member 56 is released, allowing the fixing assembly 15 to move relative to the second rod-shaped member 32, and the vertical positions of the web plate 12 and the instrument support member 14 can be adjusted together with the fixing assembly 15. Furthermore, in this case, the pressure of the third fixing member 58 is released, allowing the web plate 12 to move relative to the fixing assembly 15 within the range that the bolts 61 can move in the insertion hole 12a of the web plate 12. Thus, the vertical position of the web plate 12 can be adjusted to the same distance as the full length of the insertion hole 12a. At this point, while the fixing component 15 is fixed to the second rod-shaped member 32 as is, that is, while maintaining the vertical position of the instrument support member 14 as is, the vertical position of the web plate 12 can be adjusted independently. After adjusting the vertical position of the web plate 12, the fixing component 15 is fixed to the second rod-shaped member 32 by tightening the two bolts 61 respectively, and the fixing base 55 and the third fixing member 58 are fixed to the web plate 12.

[0050] To further adjust the vertical position of the instrument support member 14, the bolts 63 of the fixing assembly 15 are loosened. This reduces the force holding the support rod 50 between the fixing base 55 and the second fixing member 57. Consequently, the support rod 50 can move relative to the fixing assembly 15, allowing for further adjustment of the vertical position of the instrument support member 14. After adjustment, the bolts 63 of the fixing assembly 15 are tightened, thereby increasing the force holding the support rod 50 between the fixing base 55 and the second fixing member 57. Therefore, the vertical position of the instrument support member 14 is fixed, and the vertical position of the percussion instrument is also fixed.

[0051] Therefore, according to the first embodiment, the following effects can be obtained.

[0052] (1) The frame portion 30 of the back frame body 13 includes a pair of first rod-shaped members 31 on the left and right, a second rod-shaped member 32 connected to the front end of the first rod-shaped member 31, and a third rod-shaped member 33 connected to the rear end of the first rod-shaped member 31. The front extension is composed of a portion extending forward of the first rod-shaped member 31 and the second rod-shaped member 32. The main body adjustment mechanism 34 is provided at the connection between the first rod-shaped member 31 and the second rod-shaped member 32. By having the main body adjustment mechanism 34, the back frame body 13 is configured to adjust the position of the abdominal pad 21 in the front-back direction.

[0053] According to this structure, by using rod-shaped members extending from the performer's shoulders toward the abdomen, the main body 13 of the back frame can be formed almost entirely from these rod-shaped members. Therefore, compared to existing structures that use straps and boards in parts of the main body 13, the weight of the main body 13 can be reduced, and the travel back frame 10 can be made lighter. Furthermore, by adjusting the position of the abdominal pad 21 in the front-back direction, the shape of the main body 13 can be adjusted to suit the performer's body shape, particularly their thickness. Thus, regardless of the performer's body shape, the load from the travel back frame 10 can be prevented from concentrating on specific parts of the body. Therefore, the burden on the performer from the travel back frame 10 can be reduced.

[0054] (2) A main body adjustment mechanism 34 is provided at the front of the frame portion 30, that is, at each of the pair of front extensions extending from the shoulders toward the abdomen. According to this structure, the positional relationship between the parts above and below the main body adjustment mechanism 34 in the back frame body 13 can be adjusted. As a result, the front-back position of the abdominal pad 21 can be adjusted, and the shape of the back frame body 13 can be adjusted.

[0055] (3) The main body 13 of the back frame is configured such that the position of the lower torso 13b relative to the upper torso 13a can be adjusted via the main body adjustment mechanism 34. According to this structure, by adjusting the position of the lower torso 13b relative to the upper torso 13a, the shape of the main body 13 of the back frame can be adjusted to suit the performer's body shape. This allows the positions of the shoulder pads 38 and the abdominal pads 21 to be adjusted to appropriate positions. Therefore, the burden on the performer from the traveling back frame 10 can be further reduced.

[0056] (4) The main adjustment mechanism 34 is configured such that the lower torso 13b is rotatably connected to the upper torso 13a, and the rotational position of the lower torso 13b relative to the upper torso 13a is fixed. According to this structure, by rotating the lower torso 13b relative to the upper torso 13a, or by fixing the rotational position of the lower torso 13b relative to the upper torso 13a, the shape of the main body 13 of the back frame can be easily changed according to the performer's body shape. Therefore, the positions of the shoulder pads 38 and the abdominal pads 21 can be easily adjusted to appropriate positions, further reducing the burden on the performer from the traveling back frame 10.

[0057] (5) A backrest adjustment mechanism 35 is provided at the rear of the frame portion 30, specifically at each of the pair of rear extensions extending from the shoulders toward the back. According to this structure, by adjusting the position of the back pad 39 in the front-back direction using the backrest adjustment mechanism 35 in accordance with the performer's body shape, the shape of the area near the backrest 13c of the back frame body 13 can be adjusted. Therefore, regardless of the performer's body shape, the load from the traveling back frame 10 can be further reduced from concentrating on specific parts of the body. Thus, the burden on the performer from the traveling back frame 10 can be further reduced.

[0058] (6) The backrest adjustment mechanism 35 is configured such that the backrest 13c is rotatably connected to the upper torso 13a, and the rotational position of the backrest 13c relative to the upper torso 13a can be fixed. According to this structure, by rotating the backrest 13c relative to the upper torso 13a, or by fixing the rotational position of the backrest 13c relative to the upper torso 13a, the shape near the backrest 13c of the backrest body 13 can be easily changed according to the performer's body shape. Therefore, the position of the backrest pad 39 can be easily adjusted to an appropriate position, further reducing the burden on the performer from the traveling backrest 10.

[0059] (7) When viewed from above from the front, the main body adjustment mechanism 34 rotatably connects the first rod-shaped member 31 and the second rod-shaped member 32 so that they are arranged on the same straight line. According to this structure, the main body adjustment mechanism 34 is provided midway along the two front extensions extending from the performer's shoulders toward the abdomen. This allows the shape near the main body adjustment mechanism 34 of the main body 13 to be formed into a straight shape when viewed from above, resulting in a compact design. Furthermore, the number of rod-shaped members required for the main body 13 can be reduced, thus facilitating the weight reduction of the travel back frame 10. Therefore, the burden on the performer from the travel back frame 10 can be further reduced.

[0060] (8) The main adjustment mechanism 34 is equipped with a multi-plate clutch 43. According to this structure, by employing the multi-plate clutch 43, the fixing force of the second rod-shaped member 32 relative to the first rod-shaped member 31 is increased. Therefore, even when playing a percussion instrument such as a marching drum while wearing the walking frame 10, the rotational position of the lower torso 13b relative to the upper torso 13a can be fixed, and the positions of the shoulder pads 38 and the abdominal pads 21 can be fixed in appropriate positions. Furthermore, by arranging the multiple friction plates 46 constituting the multi-plate clutch 43 in an overlapping manner along the rotational axis of the second rod-shaped member 32, the shape near the connection between the first rod-shaped member 31 and the second rod-shaped member 32 can be made compact.

[0061] (9) The main body 13 of the back frame has a skeleton portion 30 composed of multiple rod-shaped members that form a ring shape as a whole. According to this structure, because the rod-shaped members constituting the main body 13 of the back frame are ring-shaped, the strength against torsion is increased compared to a main body 13 of the back frame composed of approximately U-shaped rod-shaped members. Therefore, the pivots of the left and right pair of main body adjustment mechanisms 34 are less prone to misalignment, and thus the operation of adjusting the rotational position of the lower torso 13b relative to the upper torso 13a can be performed smoothly. Similarly, the pivots of the left and right pair of rear back adjustment mechanisms 35 are also less prone to misalignment, and thus the operation of adjusting the rotational position of the rear back 13c relative to the upper torso 13a can also be performed smoothly.

[0062] (10) The instrument support member 14 is fixed to the fixing assembly 15 by means of the support rod 50, thereby being directly assembled to the lower torso 13b of the back frame body 13. According to this structure, instead of the existing structure in which the instrument support member 14 is fixed to the web plate 12, the strength required for the web plate 12 can be reduced by fixing the instrument support member 14 to the back frame body 13. As a result, it is easier to make the web plate 12 thinner and select materials, and it is easier to make the travel back frame 10 lighter. In addition, by fixing the instrument support member 14 to the back frame body 13, the instrument support member 14 is positioned near the center of the player's body. Therefore, when playing an instrument while wearing the travel back frame 10, the player's foot movements will not be hindered by the instrument support member 14.

[0063] (11) The fixing component 15 is configured to fix the second rod-shaped member 32 between the fixing base 55 and the first fixing member 56. According to this structure, by reducing the fixing force of the first fixing member 56 relative to the fixing base 55, the fixing component 15 and the instrument support member 14 can move relative to the second rod-shaped member 32 together. Furthermore, by fixing the second rod-shaped member 32 between the fixing base 55 and the first fixing member 56, the fixing component 15 and the instrument support member 14 can be fixed relative to the second rod-shaped member 32 together. Thus, by adjusting the fixing force of the second rod-shaped member 32 relative to the fixing base 55, the vertical position of the percussion instrument can be adjusted while it is supported in front of the body. Furthermore, by fixing the second rod-shaped member 32 between the fixing base 55 and the first fixing member 56, the structure of the back frame body 13 is strengthened, thereby further improving its resistance to torsion.

[0064] (12) The fixing component 15 is configured to be fixed to the web plate 12 by the third fixing member 58. According to this structure, the fixing component 15 can not only fix the instrument support member 14 to the back frame body 13, but also fix the back frame body 13 to the web plate 12. As a result, the number of parts required to assemble the instrument support member 14, the back frame body 13, and the web plate 12 can be reduced. Therefore, it is easy to reduce the weight of the travel back frame 10.

[0065] (13) A through hole 12a for fixing to the traveling frame 10 is formed in the center of the web 12. The through hole 12a extends linearly from near the upper end to near the lower end of the web 12. According to this structure, by reducing the fixing force of the third fixing member 58 relative to the web 12, the web 12 can be moved relative to the second rod-shaped member 32 in the vertical direction along the extension of the through hole 12a. In addition, by fixing the third fixing member 58 to the web 12, the web 12 can be fixed to the second rod-shaped member 32. In this way, by adjusting the fixing force of the third fixing member 58 relative to the web 12, the vertical position of the web 12 can be adjusted independently while maintaining the vertical position of the instrument support member 14 as is.

[0066] (Second Implementation)

[0067] Next, refer to Figures 7-8B A second embodiment embodying the traveling frame 70 of the present invention will be described. Detailed descriptions of the parts in the second embodiment that are the same as those in the first embodiment will be omitted.

[0068] like Figure 7As shown, the travel frame 70 includes a web plate 12, a frame body 13, an upper support member 71, a lower support member 72, and a fixing assembly 15. The web plate 12, the frame body 13, and the lower support member 72 are assembled into one piece using the fixing assembly 15. The upper support member 71 is directly assembled to the lower torso 13b of the frame body 13. The travel frame 70 is used as an instrument worn on the performer's body and for supporting vertical drums such as bass drums in front of the body.

[0069] like Figure 7 , Figure 8A and Figure 8B As shown, the bass drum 80 includes a cylindrical drum body 81 and a drumhead 82 mounted on the open end of the drum body 81. Furthermore, the bass drum 80 has a connecting shaft 84 on the outer circumferential surface of the drum body 81, which connects to the upper support member 71. The travel frame 70 is configured such that the axis of the drum body 81 is horizontal, and is configured to support the bass drum 80 at two locations on the drum body 81: a first position P1 and a second position P2. The connecting shaft 84 is fixed to the first position P1 on the drum body 81.

[0070] The upper support member 71 includes a surface member 73 and a back member 77. A bass drum 80 is connected to the surface member 73, which is fixed to the back member 77. The surface member 73 includes a rectangular plate 73a and a pair of hooks 74 fixed to both ends of the plate 73a. A fitting recess 74a with an opening at the top is formed on the upper surface of each hook 74. The connecting shaft 84 of the bass drum 80 is inserted into the two fitting recesses 74a. A pair of bolts 76 are inserted into the center of the upper support member 71. The two bolts 76 are screwed into a nut (not shown) disposed on the back side of the back member 77.

[0071] The back member 77 is made of a rectangular plate. Near the center of the back member 77, a pair of left and right rod-shaped member fixing recesses 77a are formed, for mounting the second rod-shaped member 32. The two rod-shaped member fixing recesses 77a are arranged parallel to each other and extend vertically. The rod-shaped member fixing recesses 77a are formed by bending a portion of the back member 77 along the outer peripheral surface of the second rod-shaped member 32 into a generally semi-circular shape. The back member 77 is fastened to the back of the surface member 73 by two bolts 76 and nuts, thereby fixing the second rod-shaped member 32 to the back of the surface member 73 in a state where the second rod-shaped member 32 is clamped between the two rod-shaped member fixing recesses 77a and the surface member 73.

[0072] The lower support member 72 consists of a pair of support rods 78. The support rods 78 are bent into an approximately L-shape near the center in the axial direction. A rubber cap 79 is installed at the top of each support rod 78. The support rods 78 are directly fitted to the lower body 13b of the back frame body 13 with the end without the cap 79 positioned in the space between the fixed base 55 and the second fixing member 57. The top of the support rod 78 abuts against a second position P2 on the drum body 81.

[0073] Next, refer to Figure 7 , Figure 8A and Figure 8B The function of the traveling frame 70 will be explained.

[0074] like Figure 7 , Figure 8A and Figure 8B As shown, the travel frame 70 includes an upper support member 71 that supports the bass drum 80 at a first position P1 on the drum body 81, and a lower support member 72 that supports the bass drum 80 at a second position P2, which is lower than the first position P1. The performer P adjusts the vertical position of the upper support member 71 or the lower support member 72 according to the diameter of the bass drum 80, following the steps described below. At this time, the performer P adjusts the positions of the upper support member 71 and the lower support member 72 respectively to reduce the load on the travel frame 70.

[0075] To adjust the position of the upper support member 71, the force clamping the second rod-shaped member 32 by the back member 77 and the surface member 73 is reduced by loosening the two bolts 76. As a result, the upper support member 71 can slide relative to the second rod-shaped member 32, i.e., the pair of forward extensions extending from the shoulders toward the abdomen, allowing adjustment of the vertical position of the upper support member 71. For example, in the case of supporting a large-diameter bass drum 80L, such as... Figure 8B As shown, the position of the upper support member 71 is set at a position greater than that of the upper support member 71. Figure 8A The position shown is towards the top. After adjusting the position of the upper support member 71, the force of the second rod-shaped member 32 being held by the back member 77 and the surface member 73 is strengthened by tightening the two bolts 76. Thus, the upper support member 71 is fixed to the second rod-shaped member 32, and the vertical position of the upper support member 71 is fixed.

[0076] Additionally, to adjust the position of the lower support member 72, the force clamping the support rod 78 by the fixed base 55 and the second fixing member 57 is reduced by loosening the two bolts 63. This allows the support rod 78 to move relative to the fixing assembly 15, enabling adjustment of its vertical position. For example, in the case of supporting a large-diameter bass drum 80L, such as... Figure 8B As shown, the position of the support rod 78 is set at a position greater than that of the support rod 78. Figure 8A The position shown is lower. After adjusting the position of the support rod 78, the force of the support rod 78 held by the fixed base 55 and the second fixing member 57 is strengthened by tightening the two bolts 63. As a result, the vertical position of the two support rods 78 is fixed.

[0077] Therefore, according to the second embodiment described above, the following effects can be obtained.

[0078] (1) The travel frame 10 includes: an upper support member 71 supporting a bass drum 80 at a first position P1 on the drum body 81; and a lower support member 72 supporting the bass drum 80 at a second position P2, which is lower than the first position P1. The upper support member 71 can slide relative to a pair of forward extensions, namely second rod-shaped members 32, extending from the shoulders toward the abdomen, by loosening two bolts 76. According to this structure, the upper support member 71 can slide relative to the second rod-shaped members 32 in accordance with the diameter of the bass drum 80 supported in front of the body by the travel frame 70. That is, the vertical position of the upper support member 71 can be adjusted in accordance with the diameter of the bass drum 80, and the first position on the drum body 81 supported by the travel frame 10 can be adjusted. Thus, the interval between the first and second positions on the drum body 81 supported by the travel frame 10 can be adjusted so that the load from the travel frame 10 is not concentrated on a specific part of the body. Therefore, even when playing the bass drum 80 while wearing the travel frame 10, the burden on the performer from the travel frame 10 can be reduced.

[0079] (2) The upper support member 71 is configured to fix the second rod-shaped member 32 between the surface member 73 and the back member 77. This weakens or strengthens the force that holds the second rod-shaped member 32 between the back member 77 and the surface member 73, allowing the upper support member 71 to slide or be fixed relative to the second rod-shaped member 32. Furthermore, this allows for easy adjustment of the distance between the first and second positions on the drum body 81 supported by the travel frame 10, corresponding to the diameter of the bass drum 80 supported at the front of the body. Additionally, this structure reduces the number of parts compared to a structure where a pair of upper support members 71 are provided on both sides of the back frame body 13. Therefore, weight reduction of the travel frame 10 becomes easier.

[0080] The above-described embodiments can also be modified as follows.

[0081] In the above embodiments, the back frame body 13 is configured to allow adjustment of the position of the lower torso 13b relative to the upper torso 13a. Alternatively, the upper torso 13a may be divided into two or more torsos, or the lower torso 13b may be divided into two or more torsos. In this case, the upper torso 13a may also be configured to allow adjustment of the positions of two or more torsos. Similarly, the lower torso 13b may also be configured to allow adjustment of the positions of two or more torsos.

[0082] In the embodiments described above, the main body adjustment mechanism 34 rotatably connects the lower torso 13b to the upper torso 13a. Alternatively, the main body adjustment mechanism 34 may also connect the lower torso 13b to the upper torso 13a in a manner that allows it to slide along the axis of the second rod-shaped member 32. In this case, the shape of the back frame main body 13 can be changed by adjusting the position of the lower torso 13b relative to the axial direction of the upper torso 13a.

[0083] In the above embodiments, the backrest 13c and the backrest adjustment mechanism 35 may be omitted from the backrest body 13. That is, the backrest body 13 may also be composed of an upper torso 13a and a lower torso 13b.

[0084] In the embodiments described above, the backrest adjustment mechanism 35 rotatably connects the backrest 13c to the upper torso 13a. Alternatively, the backrest adjustment mechanism 35 may also connect the backrest 13c to the upper torso 13a in a manner that allows it to slide along the axis of the third rod-shaped member 33. In this case, the shape of the back frame body 13 can be changed by adjusting the position of the backrest 13c relative to the axial direction of the upper torso 13a.

[0085] In the above embodiments, the main body adjustment mechanism 34 connects the first rod-shaped member 31 and the second rod-shaped member 32 in a state where they are arranged on the same straight line when viewed from above. Alternatively, the main body adjustment mechanism 34 may also connect the first rod-shaped member 31 and the second rod-shaped member 32 in a state where they are not arranged on the same straight line, but are offset in a direction that intersects the axis of the second rod-shaped member 32.

[0086] • In the above embodiments, the multi-plate clutch 43 may be omitted from the main body adjustment mechanism 34. For example, in the main body adjustment mechanism 34, the rotational position of the second rod-shaped member 32 relative to the first rod-shaped member 31 may be fixed by pressing the first connecting part 41b and the second connecting part 42b together.

[0087] • In the above embodiments, the skeleton portion 30 is generally ring-shaped. Alternatively, the skeleton portion 30 can be generally U-shaped by omitting the backrest 13c from the back frame body 13.

[0088] In the first embodiment, the instrument support member 14 is fixed to the fixing assembly 15 by means of a support rod 50, thereby being directly assembled to the lower body 13b of the back frame body 13. Alternatively, the instrument support member 14 may be assembled to the web plate 12 without using the fixing assembly 15.

[0089] In the embodiments described above, the insertion hole 12a formed in the center of the web 12 extends linearly from near the upper end to near the lower end of the web 12. Alternatively, the insertion hole 12a may be formed as a circular hole. In this case, the mechanism for adjusting the vertical position of the web 12 in the traveling frame 10 is omitted.

[0090] In the second embodiment, the upper support member 71 can slide relative to the second rod-shaped member 32 by loosening the two bolts 76. Alternatively, fixing holes can be formed in the second rod-shaped member 32 at multiple different vertical positions, allowing the fixing position of the upper support member 71 relative to the second rod-shaped member 32 to be changed.

[0091] • In the above embodiments, the traveling back frame 10, 70 can also be used as a device for supporting any musical instrument other than a percussion instrument such as a marching drum, such as a xylophone, glockenspiel, or a keyed instrument.
