[0009] An embodiment of the present invention will now be described with reference to the accompanying drawings. Below, we will explain a cock fixing device 20 (hereinafter referred to as "fixing device 20") for fixing a remote control unit 11 to two types of ball cocks 1A and 1B with different specifications that are installed in the underfloor piping (not shown) of a railway vehicle. Figure 1 shows the state in which the remote control unit 11 is fixed to the ball cock 1A using the fixing device 20 according to this embodiment. Note that the remote control unit 11 is an existing device. Therefore, to simplify the description of the specification, a detailed explanation of the operation unit 11 will be omitted.
[0010] As shown in FIGS. 1 to 3, the fixture 20 has a bracket 21 fabricated by steel processing or the like. The bracket 21 has a fixing plate 23 to which the housing 12 of the remote control unit 11 is fixed using a plurality of bolts 22 (four in this embodiment). Each bolt 22 is inserted into a sleeve-shaped (tube-shaped) spacer 24, thereby forming a gap between the housing 12 and the fixing plate 23 the entire length of the spacer 24. The fixing plate 23 has sides 31-34 arranged to correspond to the sides of a rectangle. The square corners of the fixing plate 23 are provided with unit mounting pieces 26 (see FIG. 4) in which bolt insertion holes 25 (see FIG. 4) through which the bolts 22 are inserted are formed. A connecting shaft insertion hole 27 (see FIG. 4) is formed in the center of the fixed plate 23. The connecting shaft 5A is inserted through the connecting shaft 5A, which connects the valve shafts of the ball cocks 1A and 1B (hereinafter referred to as "valve shafts 8A and 8B" (see FIG. 10)) to the operating shaft 14 of the operating lever 13 of the remote control unit 11. The center line of the valve shaft 8A of the ball cock 1A and the center line of the valve shaft 8B of the ball cock 1B coincide with each other.
[0011] As shown in Fig. 5, bracket 21 has one end (the "upper side" in Fig. 5) connected (coupled) to side 31 (see Fig. 4) of the fixed plate, and the other end (the "lower side" in Fig. 5) has stay plate 41 (one of the first stay plates) extending to the opposite side (the "lower side" in Fig. 1) from remote control unit 11 (see Fig. 1). Stay plate 41 is provided perpendicular to fixed plate 23, and the other end is formed wider than the one end. A notch 42 (first notch) is formed at the other end of stay plate 41, into which inlet port 2A (see Fig. 2) of ball cock 1A engages.
[0012] The cross section of the inlet-side opening 2A of the ball cock 1A taken along a plane (hereinafter referred to as the "first axis-perpendicular plane") perpendicular to the center line of the flow path of the ball cock 1A (hereinafter referred to as the "first straight line", not shown) is formed into a regular polygon (first regular polygon, "regular octagon" in this embodiment). In other words, the cutout 42 (first cutout) is formed by cutting out part of the regular polygon (first regular polygon) from the other end of the stay plate 41 (one of the first stay plates).
[0013] On both sides ("on the left and right sides" in FIG. 5) of the notch 42 at the other end of the stay plate 41, holder attachment pieces 43, 44 (first holder attachment pieces) for attaching a holder 101 (first holder) that sandwiches the inlet-side opening 2A (see FIG. 2) of the ball cock 1A are provided. The holder attachment piece 43 protrudes outward ("on the right side" in FIG. 7) from the other end of the stay plate 41, and has a bolt insertion hole 45 (first bolt insertion hole, see FIG. 9) through which a bolt 103 (see FIG. 2) inserted through a bolt insertion hole (not shown) formed in the attachment piece 102 (first attachment piece) of the holder 101 is inserted.
[0014] The holder mounting piece 44 protrudes outward (to the "right side" in FIG. 7) from the other end of the stay plate 41, and has a groove 46 (first groove, see FIG. 9) into which a neck portion 107 (see FIG. 8) of a T-shaped engaging portion 106 (first engaging portion) formed in the mounting piece 105 (see FIG. 5) of the holder 101 is inserted. The groove 46 opens toward the side opposite the holder mounting piece 43 (the "right side" in FIG. 9). The holder 101 has an arc-shaped cock holding portion 104 (first cock holding portion) formed between the mounting pieces 102 and 105, which holds (sandwiches) the inlet-side opening 2A (see FIG. 2) of the ball cock 1A between the mounting pieces 102 and 105 and the notch 42 of the stay plate 41 of the bracket 21.
[0015] As shown in FIG. 6, one end of bracket 21 (the "upper side" in FIG. 6) is connected (coupled) to side 33 (see FIG. 4) of the fixed plate, and has stay plate 61 (the other first stay plate) arranged to face stay plate 41 at a distance in the same direction as the first straight line (the flow path direction). Except for the shape of notch 62 (first notch), stay plate 61 is identical to stay plate 41 rotated 180 degrees around valve shafts 8A, 8B (see FIG. 10). Therefore, to simplify the description, a detailed description of stay plate 61 will be omitted.
[0016] The notch 62 of the stay plate 61 (the other first stay plate) is formed in an arc shape that inscribes the outlet-side mouth 3A (see FIG. 10) of the ball cock 1A, which is formed in a regular polygon (a regular octagon in this embodiment). Also, the holder 121 (first holder) that holds (sandwiches) the outlet-side mouth 3A of the ball cock 1A between the stay plate 61 of the bracket 21 and the holder 101 is the same part as the holder 101 described above.
[0017] As shown in Fig. 7, bracket 21 has one end (the "upper side" in Fig. 7) connected (coupled) to side 32 (see Fig. 4) of the fixed plate, and the other end (the "lower side" in Fig. 7) has stay plate 51 (one of the second stay plates) extending to the opposite side (the "lower side" in Fig. 1) from remote control unit 11 (see Fig. 1). Stay plate 51 is provided perpendicular to fixed plate 23, and the other end is wider than the one end. A notch 52 (second notch) is formed at the other end of stay plate 51, into which inlet opening 2B (see Fig. 3) of ball cock 1B engages.
[0018] The cross section of inlet-side opening 2B of ball cock 1B taken along a plane (hereinafter referred to as the "second axis-perpendicular plane") perpendicular to the center line of the flow path of ball cock 1B (hereinafter referred to as the "second straight line", not shown) is formed into a regular polygon (second regular polygon, "regular octagon" in this embodiment) similar to the regular polygon (first regular polygon) of the cross section of inlet-side opening 2A of ball cock 1A (see FIG. 1) taken along the first axis-perpendicular plane. In other words, notch 52 (second notch) of stay plate 51 (one of the second stay plates) is formed by cutting out part of the regular polygon (second regular polygon) from the other end of stay plate 51.
[0019] Furthermore, in this embodiment, phase A of the regular polygon (first regular polygon) of the inlet-side opening 2A of ball cock 1A around a first line is different from phase B of the regular polygon (second regular polygon) of the inlet-side opening 2B of ball cock 1B around a second line. For example, if the phase of phase A is 0 degrees, the phase of phase B is 45 degrees. In other words, if phase A of the regular polygon (first regular polygon) including the notch 42 (first notch) of stay plate 41 (one of the first stay plates) around a first line is 0 degrees, then phase B of the regular polygon (second regular polygon) including the notch 52 (second notch) of stay plate 51 (one of the second stay plates) around a second line is 45 degrees.
[0020] Holder mounting pieces 53, 54 (second holder mounting pieces) for mounting a holder 111 (second holder) that sandwiches an inlet-side opening 2B (see FIG. 3) of the ball cock 1B are provided on both sides ("left and right sides" in FIG. 7) of the notch 52 at the other end of the stay plate 51. The holder mounting piece 53 protrudes outward ("left side" in FIG. 5) from the other end of the stay plate 51, and has a bolt insertion hole 55 (second bolt insertion hole, see FIG. 9) through which a bolt 113 (see FIG. 3) inserted through a bolt insertion hole (not shown) formed in the mounting piece 112 (second mounting piece) of the holder 111 is inserted.
[0021] The holder mounting piece 54 protrudes outward from the other end of the stay plate 51, and has a groove 56 (second groove, see FIG. 9) into which a neck portion 117 (see FIG. 3) of a T-shaped engaging portion 116 (second engaging portion) formed in the mounting piece 115 (see FIG. 3) of the holder 111 is inserted. The groove 56 opens toward the side opposite the holder mounting piece 53 (the "upper side" in FIG. 9). The holder 111 has an arc-shaped cock holding portion 114 (second cock holding portion) formed between the mounting pieces 112, 115, which holds (sandwiches) the inlet-side opening 2B (see FIG. 3) of the ball cock 1B between the mounting pieces 112, 115 and the notch 52 of the stay plate 51 of the bracket 21.
[0022] As shown in FIG. 8, one end of bracket 21 (the "upper side" in FIG. 8) is connected (coupled) to side 34 (see FIG. 4) of the fixed plate, and bracket 21 has stay plate 71 (the other second stay plate) arranged opposite stay plate 51 (one second stay plate) at a distance in the same direction as the second straight line (the flow path direction). Except for the shape of notch 72 (second notch), stay plate 71 is identical to stay plate 51 rotated 180 degrees around valve shafts 8A, 8B (see FIG. 10). Therefore, to simplify the description, a detailed description of stay plate 71 will be omitted.
[0023] The notch 72 of the stay plate 71 (the other second stay plate) is formed in an arc shape that inscribes the outlet-side opening 3B (see FIG. 10) of the ball cock 1B, which is formed in a regular polygon (a regular octagon in this embodiment). Also, the holder 131 (second holder, see FIG. 1) that holds (sandwiches) the outlet-side opening 3B of the ball cock 1B between the stay plate 71 of the bracket 21 and the holder 111 is the same part as the holder 111 described above.
[0024] Next, the operation of this embodiment will be described. When fixing fixture 20 to ball cock 1A, bracket 21 is placed over ball cock 1A, and notch 42 of stay plate 41 of bracket 21 is engaged with inlet port 2A of ball cock 1A, while notch 62 of stay plate 61 of bracket 21 is engaged with outlet port 3A of ball cock 1A. At this time, connecting shaft 5A connected to valve shaft 8A of ball cock 1A is inserted into connecting shaft insertion hole 27 of fixing plate 23 of bracket 21.
[0025] Next, the neck portion 107 of the T-shaped engaging portion 106 (first engaging portion) of the holder 101 (first holder) is inserted into the groove portion 46 (first groove portion) of the holder mounting piece 44 of the stay plate 41 of the bracket 21. In this state, the bolt 103 is inserted through the bolt insertion hole (not shown) of the mounting piece 102 (first mounting piece) of the holder 101 and the bolt insertion hole 45 (first bolt insertion hole) of the holder mounting piece 43 (first holder mounting piece) of the stay plate 41 of the bracket 21. Next, the nut 108 (see FIG. 1) is screwed onto the bolt 103, and the nut 108 is tightened. As a result, the inlet-side opening 2A of the ball cock 1A is clamped between the stay plate 41 of the bracket 21 and the holder 101.
[0026] Similarly, the neck portion 127 of the T-shaped engaging portion 126 (first engaging portion) of the holder 121 (first holder) is inserted into the groove portion 66 (first groove portion, see FIG. 9 ) of the holder mounting piece 64 of the stay plate 61 of the bracket 21. In this state, a bolt (not shown) is inserted through the bolt insertion hole (not shown) of the mounting piece 122 (first mounting piece) of the holder 121 and the bolt insertion hole 65 (first bolt insertion hole) of the holder mounting piece 63 (first holder mounting piece) of the stay plate 61 of the bracket 21. Next, a nut (not shown) is screwed onto the bolt and tightened. As a result, the outlet-side mouth portion 3A of the ball cock 1A is clamped between the stay plate 61 of the bracket 21 and the holder 121, and the fixing device 20 is fixed to the ball cock 1A.
[0027] On the other hand, when fixing fixture 20 to ball cock 1B, bracket 21 is placed over ball cock 1B, and notch 52 of stay plate 51 of bracket 21 is engaged with inlet port 2B of ball cock 1B, and notch 72 of stay plate 71 of bracket 21 is engaged with outlet port 3B of ball cock 1B. At this time, connecting shaft 5B connected to valve shaft 8B of ball cock 1B is inserted into connecting shaft insertion hole 27 of fixing plate 23 of bracket 21.
[0028] Next, the neck portion 117 of the T-shaped engaging portion 116 (second engaging portion) of the holder 111 (second holder) is inserted into the groove portion 56 (second groove portion) of the holder mounting piece 54 (second holder mounting piece) of the stay plate 51 of the bracket 21. In this state, the bolt 113 is inserted through the bolt insertion hole (not shown) of the mounting piece 112 (second mounting piece) of the holder 111 and the bolt insertion hole 55 (second bolt insertion hole) of the holder mounting piece 53 (second holder mounting piece) of the stay plate 51 of the bracket 21. Next, a nut (not shown) is screwed onto the bolt 113 and tightened. As a result, the inlet-side opening 2B of the ball cock 1B is clamped between the stay plate 51 of the bracket 21 and the holder 111.
[0029] Similarly, the neck portion (not shown) of the T-shaped engaging portion 136 of the holder 131 (second holder) is inserted into the groove portion 76 (second groove portion, see FIG. 9) of the holder mounting piece 74 (second holder mounting piece) of the stay plate 71 of the bracket 21. In this state, the bolt 133 (see FIG. 3) is inserted through the bolt insertion hole (not shown) of the mounting piece 132 (second mounting piece) of the holder 131 and the bolt insertion hole 75 (second bolt insertion hole) of the holder mounting piece 73 (second holder mounting piece) of the stay plate 71 of the bracket 21. Next, a nut (not shown) is screwed onto the bolt 133 and tightened.
[0030] As a result, the outlet-side opening 3B of the ball cock 1B is clamped between the stay plate 71 of the bracket 21 and the holder 131, and the fixture 20 is fixed to the ball cock 1B. In this embodiment, the distance from the fixing plate 23 to the second straight line is longer than the distance from the fixing plate 23 to the first straight line.
[0031] Here, in the past, even for vehicles of the same type (series), different ball cocks were used for various reasons, and therefore it was necessary to prepare dedicated fixing devices for each ball cock with different specifications, which caused manufacturing costs to increase.
[0032] In contrast, in this embodiment, when fixing device 20 is fixed to ball cock 1A, notch 42 (first notch) of stay plate 41 (first stay plate) of bracket 21 is engaged with inlet side mouth portion 2A of ball cock 1A, and inlet side mouth portion 2A of ball cock 1A is clamped (held) by stay plate 41 and holder 101 (first holder), and notch 62 (first notch) of stay plate 61 (first stay plate) of bracket 21 is engaged with outlet side mouth portion 3A of ball cock 1A, and outlet side mouth portion 3A of ball cock 1A is clamped (held) by stay plate 61 and holder 121 (first holder). On the other hand, when fixing fixture 20 to ball cock 1B, notch 52 (second notch) of stay plate 51 (second stay plate) of bracket 21 is engaged with inlet side mouth portion 2B of ball cock 1B, and inlet side mouth portion 2B of ball cock 1B is clamped (held) by stay plate 51 and holder 111 (second holder), and notch 72 (second notch) of stay plate 71 (second stay plate) of bracket 21 is engaged with outlet side mouth portion 3B of ball cock 1B, and outlet side mouth portion 3B of ball cock 1B is clamped (held) by stay plate 71 and holder 131 (second holder). According to this embodiment, one fixture 20 can be fixed to two types of ball cocks 1A, 1B with different specifications (dimensions). This eliminates the need to prepare dedicated fixtures for each of the ball cocks 1A, 1B, thereby reducing manufacturing costs. It is also possible to reduce the number of parts, simplifying parts management. In addition, in this embodiment, the cutout portion 42 (first cutout portion) is formed by cutting out the other end of the stay plate 41 (first stay plate) into a part of a regular polygon (first regular polygon) in a cross section taken along a plane perpendicular to the first axis of the mouth portion 2A of the ball cock 1A, and the cutout portion 52 (second cutout portion) is formed by cutting out the other end of the stay plate 51 (second stay plate) into a part of a regular polygon (second regular polygon) that is similar to the regular polygon (first regular polygon) in a cross section taken along a plane perpendicular to the first axis of the mouth portion 2A on the inlet side of the ball cock 1A, and the phase A of the regular polygon (first regular polygon) including the cutout portion 42 about the first line is different from the phase B of the regular polygon (second regular polygon) including the cutout portion 52 about the second line. According to this embodiment, for example, one fixture 20 can be used even if the ball cocks (1A, 1B) are made by different manufacturers and have different phases (orientations) of the openings.
[0033] Furthermore, as shown in FIG. 10, ball cocks 1A and 1B are integrated into the body by screwing body caps 7A and 7B onto main body 6A and 6B in which balls 4A and 4B are set. Therefore, the phase of the regular polygonal ball cock flow path formed by the mouth (hereinafter referred to as the "mouth phase") around the center is constant on the main body 6A and 6B side (in this embodiment, "0 degrees" for ball cock 1A and "45 degrees" for ball cock 1B) but varies on the body caps 7A and 7B side. In this embodiment, notch portions 42 (first notch portion) and notch portions 52 (second notch portion) formed by cutting out parts of regular polygons (first regular polygon and second regular polygon) in stay plates 41 (one of the first stay plates) and 51 (one of the second stay plates) are engaged with openings 2A and 2B on the main body 6A and 6B side (the "inlet side" in this embodiment), where the phase of ball cocks 1A and 1B is constant, and connecting shafts 5A and 5B of ball cocks 1A and 1B are inserted into connecting shaft insertion holes 27 formed in bracket 21, so that the relative positional relationship between bracket 21 and ball cocks 1A and 1B can be constant. This allows the connecting shafts 5A and 5B of ball cocks 1A and 1B to protrude perpendicularly from the fixing plate 23 of the bracket 21; in other words, the remote control unit 11 can be fixed to the ball cocks 1A and 1B with the valve shafts 8A and 8B of ball cocks 1A and 1B perpendicular to the remote control unit 11. Furthermore, notches 62 and 72 formed by cutting out stay plate 61 (the other first stay plate) and stay plate 71 (the other second stay plate) in an arc shape inscribed with the openings 3A and 3B on the body cap 7A and 7B side (the "outlet side" in this embodiment) of ball cocks 1A and 1B are engaged with the openings on the body cap side of ball cocks 1A and 1B, so that the notches 62 and 72 can be engaged with the openings 3A and 3B on the body cap 7A and 7B side regardless of variations in the phase of the openings 3A and 3B on the body cap 7A and 7B side.
[0034] In this embodiment, the neck portions 107, 127 (117, 137) of the T-shaped engaging portions 106, 126 (116, 136) of the mounting pieces 105, 125 (115, 135) of the holders 101, 121 (111, 131) are inserted into the groove portions 46, 66 (56, 76) of the holder mounting pieces 44, 64 (54, 74) of the stay plates 41, 61 (51, 71) of the bracket 21. In this state, the holder mounting pieces 44, 64 (54, 74) of the stay plates 41, 61 (51, 71) of the bracket 21 and the holders 101, 121 (111, 131) are inserted into the groove portions 46, 66 (56, 76) of the holder mounting pieces 44, 64 (54, 74) of the stay plates 41, 61 (51, 71) of the bracket 21. Since the mounting pieces 105, 125 (115, 135) of the holder 101, 121 (111, 131) are configured to be clamped (pulled together) by bolts and nuts (symbols omitted), the number of bolts and nuts used can be reduced to half compared to a configuration in which the holder mounting pieces 44, 64 (54, 74) of the stay plates 41, 61 (51, 71) and the mounting pieces 105, 125 (115, 135) of the holder 101, 121 (111, 131) are clamped together by bolts and nuts, and the installation work of the remote control unit 11 can be made more efficient.
[0035] The embodiment is not limited to the above-described form, and can be configured as follows, for example. In this embodiment, the cross-sectional shape (first regular polygon) of the inlet side mouth portion 2A of ball cock 1A taken on a plane perpendicular to the first axis (first regular polygon) and the cross-sectional shape (second regular polygon) of the inlet side mouth portion 2B of ball cock 1B taken on a plane perpendicular to the second axis (second regular polygon) are similar regular octagons, but they do not necessarily have to be similar; for example, the cross-sectional shape (first regular polygon) of the inlet side mouth portion 2A on the ball cock 1A side or the cross-sectional shape (second regular polygon) of the inlet side mouth portion 2B on the ball cock 1B side may be a regular hexagon. In addition, in this embodiment, phase A around a first line of the regular polygon (first regular polygon) of the inlet side mouth portion 2A of the ball cock 1A is different from phase B around a second line of the regular polygon (second regular polygon) of the inlet side mouth portion 2B of the ball cock 1B, but the phase of phase A and the phase of phase B may be the same.
