従来、下記の特許文献１に記載されたスタンチョンや図５ないし図８に示すスタンチョン等が知られている。 Conventionally, the stanchions described in the following Patent Document 1 and the stanchions shown in FIGS. 5 to 8 are known.

図５ないし図８に示すスタンチョン１は、複数の固定柵棒２と、固定柵棒２と離間対向し作用方向への回動により鉛直状の作用状態となり自重に基づく非作用方向への回動により傾斜状の非作用状態になり作用状態時には牛等の家畜Ａの首を固定柵棒２とともに左右から挟持する複数の回動柵棒３と、回動柵棒３を前後方向の軸４を中心として回動可能に支持する複数の略く字状の屈曲柵棒５とを備えている。 5 to FIG. 8 includes a plurality of fixed fence bars 2 and a fixed fence bar 2 spaced apart from each other and turned into a vertical action state by rotating in the action direction, and turning in a non-action direction based on its own weight. A plurality of rotating fence bars 3 for holding the neck of a livestock A such as cows together with the fixed fence bars 2 from the left and right, and an axis 4 in the front-rear direction. And a plurality of substantially square-shaped bent fence bars 5 that are pivotally supported around the center.

また、スタンチョン１は、回動柵棒３を作用状態にロックして家畜Ａを捕獲するロック手段６を備えている。ロック手段６は、回動柵棒３の上端部に設けられ互いに離間対向する前後一対の対向プレート７を有し、これら両対向プレート７には第１支軸８および第２支軸９が架設されている。第１支軸８には第１回動板11の上端部が回動可能に取り付けられ、この第１回動板11はその第１支軸８を中心として上下方向に回動する。第２支軸９には第２回動板12の上端部が回動可能に取り付けられ、この第２回動板12はその第２支軸９を中心として上下方向に回動する。 In addition, the stanchion 1 is provided with a lock means 6 that locks the rotating fence bar 3 in the operating state and captures the livestock A. The locking means 6 has a pair of front and rear opposing plates 7 provided at the upper end of the rotating fence bar 3 and facing each other. The first supporting shaft 8 and the second supporting shaft 9 are installed on both the opposing plates 7. Has been. An upper end portion of a first rotation plate 11 is rotatably attached to the first support shaft 8, and the first rotation plate 11 rotates in the vertical direction around the first support shaft 8. An upper end portion of the second rotation plate 12 is rotatably attached to the second support shaft 9, and the second rotation plate 12 rotates in the vertical direction around the second support shaft 9.

さらに、両対向プレート７間には水平棒13が挿通され、この水平棒13は、第１回動板11の下端部が当接係合するストッパ突部14と、棒状のハンドル部15とを有している。また、水平棒13は、第２回動板12の下端部が当接係合するストッパを兼ねた軸支持体16にて左右方向の軸線を中心として回動可能に支持されている。 Further, a horizontal bar 13 is inserted between the opposing plates 7, and the horizontal bar 13 includes a stopper protrusion 14 with which the lower end of the first rotating plate 11 abuts and a bar-like handle portion 15.

しかしながら、図５ないし図８に示す従来のスタンチョン１では、回動柵棒３の作用状態時に牛等の家畜Ａの肩が固定柵棒２および回動柵棒３にぶつかるため、家畜Ａは餌を食べづらく、また家畜Ａにとって苦痛で、ストレスを与えてしまう問題がある。 However, in the conventional stanchion 1 shown in FIGS. 5 to 8, since the shoulder of the livestock A such as cattle hits the fixed fence bar 2 and the rotary fence bar 3 when the rotary fence bar 3 is in an operating state, There is a problem that it is difficult to eat the food, and it is painful for the livestock A and gives stress.

そこで、例えば図９に示すように、固定柵棒２および回動柵棒３等を上端ほど家畜Ａの胴体から離れるように前傾させて配置することが考えられるが、この図９に示す構成では次のような問題がある。 Therefore, for example, as shown in FIG. 9, it is conceivable to place the fixed fence bar 2 and the rotating fence bar 3 and the like so as to be farther away from the body of the livestock A toward the upper end. Then there are the following problems.

すなわち、回動柵棒３の前傾により第１支軸８が前端ほど下方に位置するように傾斜し、この第１支軸８の傾斜により第１回動板11も傾斜状態に配置されるため、第１回動板11の下端部と水平棒13のストッパ突部14との当接係合が不用意に解除されるおそれがある。 That is, the first support shaft 8 is inclined so that the front end thereof is positioned downward as the front end of the rotating fence bar 3 is inclined, and the first rotation plate 11 is also disposed in an inclined state by the inclination of the first support shaft 8. Therefore, the contact engagement between the lower end of the first rotating plate 11 and the stopper protrusion 14 of the horizontal bar 13 may be inadvertently released.

つまり、図１０に示すように、第１回動板11が傾斜状態に配置されると、第１回動板11が自重で第１支軸８に沿って前方に若干ずれ、第１回動板11の前端部が前側の対向プレート７における後側の対向プレート７との対向面と接触する。このため、家畜Ａが回動柵棒３に衝突し、その勢いで第１回動板11が傾斜状の第１支軸８を中心として上方に回動した際に、その第１回動板11の下方への戻りが、第１支軸８が水平状の場合に比べて遅くなり、その間に回動柵棒３が自重で非作用方向へ回動し、第１回動板11の下端部と水平棒13のストッパ突部14との当接係合が解除されてしまうことがある。 That is, as shown in FIG. 10, when the first rotation plate 11 is disposed in an inclined state, the first rotation plate 11 is slightly shifted forward along the first support shaft 8 by its own weight, so that the first rotation The front end of the plate 11 is in contact with the surface of the front counter plate 7 that faces the rear counter plate 7. For this reason, when the livestock A collides with the rotating fence bar 3 and the first rotating plate 11 rotates upwardly around the inclined first support shaft 8 with the momentum, the first rotating plate The lower return of 11 is slower than the case where the first support shaft 8 is horizontal, during which the rotating fence bar 3 rotates in its non-operating direction under its own weight, and the lower end of the first rotating plate 11 The contact engagement between the portion and the stopper protrusion 14 of the horizontal bar 13 may be released.

本発明は、このような点に鑑みなされたもので、家畜が餌を食べやすくなり、苦痛による家畜へのストレスを抑制できるばかりでなく、回動板の下端部と水平棒のストッパ突部との当接係合が不用意に解除されるのを防止できるため、回動柵棒を作用状態に適切に維持でき、家畜の捕獲が確実となるスタンチョンに関するものである。 The present invention has been made in view of the above points, and it is easy for livestock to eat and not only can suppress stress on livestock due to pain, but also the lower end of the rotating plate and the stopper protrusion of the horizontal bar. It is possible to prevent the abutment engagement from being inadvertently released, so that the rotating fence bar can be appropriately maintained in the operating state, and the stanchion can reliably capture livestock.

請求項１記載のスタンチョンは、固定柵棒と、この固定柵棒と離間対向し、作用方向への回動により作用状態となり、自重に基づく非作用方向への回動により非作用状態になり、作用状態時には家畜の首を前記固定柵棒とともに挟持する回動柵棒と、この回動柵棒を作用状態にロックするロック手段とを備え、前記ロック手段は、前記回動柵棒の上端部に設けられ、互いに離間対向する前後一対の対向プレートと、これら両対向プレートに架設された支軸と、この支軸に上端部が取り付けられ、この支軸を中心として上下方向に回動する回動板と、前記両対向プレート間に挿通され、ストッパ突部を有する左右方向の水平棒とを有し、前記回動柵棒の作用状態時に、前記回動板の下端部と前記ストッパ突部との当接係合により前記回動柵棒の非作用方向への回動が規制されるスタンチョンであって、前記固定柵棒および前記回動柵棒が上端ほど家畜の胴体から離れるように傾斜する前傾状態に配置され、かつ前記支軸が水平状態に配置されているものである。 The stanchion according to claim 1 is opposed to the fixed fence bar and the fixed fence bar, and is activated by rotating in the acting direction, and deactivated by rotating in the non-acting direction based on its own weight.

Of the rotating fence bar It is a stanchion that is restricted from rotating in the direction of action, and the fixed fence bar and the pivot fence bar are arranged in a forward inclined state in which the upper end of the fixed fence bar and the rotary fence bar are inclined so as to move away from the body of the livestock, and the support shaft is It is arranged horizontally.

請求項２記載のスタンチョンは、請求項１記載のスタンチョンにおいて、ロック手段の水平棒は、ハンドル部を有し、前記ハンドル部を把持して前記水平棒を左右方向の軸線を中心として回動操作すると、回動板の下端部とストッパ突部との当接係合が解除され、回動柵棒が自重で非作用方向へ回動するものである。 The stanchion according to claim 2 is the stanchion according to claim 1, wherein the horizontal bar of the locking means has a handle part, and grips the handle part to rotate the horizontal bar around a horizontal axis. When the moving operation is performed, the contact engagement between the lower end portion of the rotating plate and the stopper protrusion is released, and the rotating fence bar rotates in its non-acting direction under its own weight.

本発明によれば、固定柵棒および回動柵棒が上端ほど家畜の胴体から離れるように傾斜する前傾状態に配置され、かつ支軸が水平状態に配置されているため、家畜が餌を食べやすくなり、苦痛による家畜へのストレスを抑制できるばかりでなく、回動板の下端部と水平棒のストッパ突部との当接係合が不用意に解除されるのを防止できるため、回動柵棒を作用状態に適切に維持でき、家畜の捕獲が確実となる。 According to the present invention, the fixed fence bar and the rotating fence bar are arranged in a forward tilt state in which the upper end is inclined away from the body of the livestock, and the support shaft is arranged in a horizontal state. This makes it easier to eat and suppresses stress on livestock caused by pain, as well as preventing the contact engagement between the lower end of the rotating plate and the stopper protrusion of the horizontal bar from being inadvertently released. The moving fence bar can be properly maintained in the working state, and the capture of livestock is ensured.

That is, for example, the angle α formed by the axis a of the rotating fence rod 27 and the vertical line b in the vertical direction in a side view is 5 to 15 degrees, preferably 15 degrees.

また、スタンチョン21は、回動柵棒27を作用状態にロックして家畜Ａを捕獲するロック手段31を備えている。ロック手段31は、回動柵棒27の上端部外周側に取り付けられ互いに離間対向する前後一対の略板状の対向プレート32を有している。 Further, the stanchion 21 is provided with a locking means 31 for capturing the livestock A by locking the rotating fence rod 27 in the operating state. The locking means 31 includes a pair of front and rear substantially plate-like opposing plates 32 that are attached to the outer peripheral side of the upper end of the rotating fence rod 27 and face each other.

各対向プレート32は、回動柵棒27の上端部外周面に対応した円弧面状の取付板部33と、この取付板部33の上端に一体に設けられた対向板部34とにて構成され、両対向板部34の上端部同士が連結杆35にて連結されている。対向板部34は、上下方向略中央の１箇所で折り曲げられた屈曲板にて構成され、下部に傾斜板36を有し上部に鉛直板37を有している。 Each counter plate 32 is composed of an arcuate mounting plate 33 corresponding to the outer peripheral surface of the upper end of the rotating fence rod 27, and a counter plate 34 integrally provided at the upper end of the mounting plate 33. The upper ends of the opposing plate portions 34 are connected by a connecting rod 35. The counter plate portion 34 is formed of a bent plate bent at one place in the substantially vertical center, and has an inclined plate 36 at the lower portion and a vertical plate 37 at the upper portion.

前後に互いに離間対向する両鉛直板37には、第１支軸（支軸）41および第２支軸42が架設され、各支軸41，42は水平状態に配置されている。また、互いに離間対向する両傾斜板36間には、水平な上棒29が挿通されている。 A first support shaft (support shaft) 41 and a second support shaft 42 are installed on both vertical plates 37 that are spaced apart from each other in the front-rear direction, and the support shafts 41 and 42 are arranged in a horizontal state. Further, a horizontal upper bar 29 is inserted between the inclined plates 36 that are spaced apart from each other.

そして、水平状態の第１支軸41には略矩形板状の第１回動板（回動板）43の上端部が回動可能に取り付けられており、この水平状態に配置された第１回動板43は、その第１支軸41を中心として上下方向に回動する。また、水平状態の第２支軸42には略矩形板状の第２回動板44の上端部が回動可能に取り付けられており、この水平状態に配置された第２回動板44は、その第２支軸42を中心として上下方向に回動する。各回動板43，44は同一形状のもので、上端部に略円筒状の軸挿通部45を有し、この軸挿通部45に支軸41，42が挿通されている。 And the upper end part of the substantially rectangular plate-shaped 1st rotation board (rotation board) 43 is rotatably attached to the 1st spindle 41 of a horizontal state, The 1st arrange | positioned in this horizontal state The rotating plate 43 rotates in the vertical direction around the first support shaft 41. Further, the upper end of a substantially rectangular plate-like second rotating plate 44 is rotatably attached to the second support shaft 42 in the horizontal state, and the second rotating plate 44 arranged in the horizontal state is The second pivot 42 is pivoted in the vertical direction. Each of the rotating plates 43 and 44 has the same shape, and has a substantially cylindrical shaft insertion portion 45 at the upper end, and the support shafts 41 and 42 are inserted through the shaft insertion portion 45.

また、互いに離間対向する両対向板部34間には、左右方向に延びる１本の水平棒46が挿通されている。そして、この水平棒46は、第１回動板43の下端部との当接係合により回動柵棒27の非作用方向への回動を規制して回動柵棒27を作用状態にロックする複数の略直方体状のストッパ突部47と、回動柵棒27のロックを解除する際に操作する棒状のハンドル部48とを有している。ストッパ突部47は、水平棒46のうち各回動柵棒27に対応する部分に突出形成され、ハンドル部48は水平棒46の端部に突出形成されている。さらに、水平棒46は、第２回動板44の下端部との当接係合により回動柵棒27が作用方向へ必要以上に回動するのを規制するストッパを兼ねた軸支持体51にて左右方向の軸線ｃを中心として回動可能に支持されている。 In addition, a single horizontal bar 46 extending in the left-right direction is inserted between the opposing plate portions 34 that are spaced apart from each other. And this horizontal bar | burr 46 controls rotation to the non-operation direction of the rotation fence bar 27 by contact | abutting engagement with the lower end part of the 1st rotation board 43, and makes the rotation fence bar 27 active state. A plurality of substantially rectangular parallelepiped stopper protrusions 47 to be locked and a rod-like handle portion 48 that is operated when unlocking the rotating fence rod 27 are provided. The stopper protrusion 47 is formed to protrude from a portion of the horizontal bar 46 corresponding to each rotating fence bar 27, and the handle portion 48 is formed to protrude from the end of the horizontal bar 46. Further, the horizontal bar 46 is a shaft support 51 that also serves as a stopper that restricts the rotating fence bar 27 from rotating more than necessary in the operating direction by abutting engagement with the lower end of the second rotating plate 44. Is supported so as to be rotatable about a horizontal axis c.

次に、上記スタンチョン21の作用等を説明する。 Next, the operation and the like of the above-mentioned stunch 21 will be described.

図示しない餌箱内に餌を入れると、牛等の家畜Ａは、互いに離間対向する固定柵棒26および回動柵棒27間に頭を突っ込んだ後、餌に向って頭を下げる。すると、回動柵棒27の下部が家畜Ａにて押され、回動柵棒27が支軸を中心として作用方向に向って回動して作用状態となり、作用状態の回動柵棒27とこの回動柵棒27と離間対向する固定柵棒26とにて家畜Ａの首が挟持される。 When food is put into a food box (not shown), the livestock A such as cows pushes his head between the fixed fence bar 26 and the rotating fence bar 27 facing each other and then lowers his head toward the food. Then, the lower part of the rotating fence bar 27 is pushed by the livestock A, and the rotating fence bar 27 is rotated in the action direction around the support shaft to be in an action state. The neck of the livestock A is clamped between the rotating fence bar 27 and the fixed fence bar 26 that is opposed to and separated from the rotary fence bar 27.

この回動柵棒27の作用方向への回動時には、第１回動板43の下端部が、第１回動板43の自重に基づいて水平棒46に接触した状態でこの水平棒46上をスライド移動してストッパ突部47を乗り越えた後、このストッパ突部47の端部と当接係合し、この第１回動板43の下端部とストッパ突部47との当接係合により回動柵棒27の自重に基づく非作用方向への回動が規制され、回動柵棒27が所望の作用状態にロックされ、こうして家畜Ａが捕獲される。また、第２回動板44の下端部は水平棒46上をスライド移動して軸支持体51と当接係合し、この第２回動板44の下端部と軸支持体51との当接係合により回動柵棒27が作用方向へ必要以上に回動することが規制される。 When the rotating fence rod 27 is rotated in the acting direction, the lower end portion of the first rotating plate 43 is in contact with the horizontal rod 46 based on the weight of the first rotating plate 43. After sliding over the stopper projection 47, it is brought into contact with the end of the stopper projection 47, and the lower end of the first rotating plate 43 is brought into contact with the stopper projection 47. Thus, the rotation of the rotating fence bar 27 in the non-acting direction based on its own weight is restricted, and the rotating fence bar 27 is locked in a desired operating state, and thus the livestock A is captured. The lower end of the second rotating plate 44 slides on the horizontal bar 46 and comes into contact with and engages with the shaft support 51, and the lower end of the second rotating plate 44 and the shaft support 51 are brought into contact with each other. By the contact engagement, the rotation fence rod 27 is restricted from rotating more than necessary in the operation direction.

そして、作業者は、スタンチョン21で捕獲した複数頭の家畜Ａに対して、予防接種等の所定作業を順次行う。 Then, the worker sequentially performs predetermined work such as vaccination on the plurality of livestock A captured in the stunchon 21.

また、所定作業終了後、家畜Ａを一斉に開放する場合、作業者は、水平棒46のハンドル部48を把持し、このハンドル部48を押し下げるようにして水平棒46を左右方向の軸線ｃを中心に略９０度回動操作する。すると、複数のストッパ突部47が水平棒46とともに回動し、第１回動板43の下端部とストッパ突部47との当接係合が解除され、回動柵棒27が自重で非作用方向へ回動して非作用状態になる。 In addition, when the livestock A is released all at once after the predetermined work is completed, the operator holds the handle portion 48 of the horizontal bar 46 and pushes down the handle part 48 so that the horizontal bar 46 has the horizontal axis c. Rotate approximately 90 degrees to the center. Then, the plurality of stopper protrusions 47 rotate together with the horizontal bar 46, the contact engagement between the lower end portion of the first rotation plate 43 and the stopper protrusion 47 is released, and the rotation fence bar 27 is non-weighted. Rotates in the direction of action and becomes inactive.

なお、家畜Ａを開放した後には、ハンドル部48を持ち上げるようにして水平棒46を左右方向の軸線ｃを中心に略９０度回動操作することにより、自動ロックの待機状態にしておく。 After the livestock A is opened, the horizontal bar 46 is turned about 90 degrees about the left-right axis c so as to lift the handle portion 48, thereby setting the automatic lock standby state.

そして、このようなスタンチョン21によれば、固定柵棒26および回動柵棒27が上端ほど家畜Ａの胴体から離れるように傾斜する前傾状態に配置され、かつ第１回動板43を回動可能に支持する第１支軸41が水平状態に配置されているため、家畜Ａが餌を食べやすくなり、苦痛による家畜Ａへのストレスを抑制できるばかりでなく、図１０に示すような第１回動板43の下方への戻りが遅くなる不具合が発生せず、第１回動板43の下端部と水平棒46のストッパ突部47との当接係合が不用意に解除されるのを防止できるため、回動柵棒27を作用状態に適切に維持でき、家畜Ａの捕獲が確実となり、よって例えば予防接種等の所定作業を安全に行うことができる。 According to such a stanchion 21, the fixed fence bar 26 and the rotary fence bar 27 are arranged in a forward inclined state in which the upper end of the fixed fence bar 26 and the rotary fence bar 27 are inclined away from the body of the livestock A, and the first rotary plate 43 is disposed. Since the first support shaft 41 that is pivotally supported is arranged in a horizontal state, the livestock A can easily eat food and can suppress the stress on the livestock A due to pain, as shown in FIG. There is no problem that the return of the first rotating plate 43 to the lower side is delayed, and the contact engagement between the lower end portion of the first rotating plate 43 and the stopper projection 47 of the horizontal bar 46 is inadvertently released.
