しかしながら、斯かる樹木径測定器においては、マーキング手段が挟み体に固定されているため、測定する樹木の大きさによっては、マーキング手段が樹木に対して適切な位置に配置されてない場合があった。   However, in such a tree diameter measuring instrument, since the marking means is fixed to the sandwiching body, the marking means may not be arranged at an appropriate position with respect to the tree depending on the size of the tree to be measured. It was.

よって、本発明は、かかる事情に鑑み、測定する樹木の大きさに関わらず、マーキング手段が樹木に対して適切な位置に配置できる樹木径測定器を提供することを課題とする。   Therefore, in view of such circumstances, an object of the present invention is to provide a tree diameter measuring instrument in which a marking unit can be arranged at an appropriate position with respect to a tree regardless of the size of the tree to be measured.

本発明に係る樹木径測定器は、樹木を挟むことにより樹木の径を測定すべく、接離可能な一対の挟み体と、樹木にマーキングするためのマーキング手段とを備える樹木径測定器において、マーキング手段は、一対の挟み体が接離する方向で、少なくとも一方の挟み体に対して相対的に変位可能に構成されることを特徴とする。   The tree diameter measuring device according to the present invention is a tree diameter measuring device comprising a pair of detachable sandwiching bodies and a marking means for marking a tree in order to measure the diameter of the tree by sandwiching the tree, The marking means is configured to be relatively displaceable with respect to at least one of the sandwiching bodies in a direction in which the pair of sandwiching bodies are in contact with or separated from each other.

Mesh with a relatively displaceable movable rack. Thereby, since a gear mechanism rotates as a pair of clamping body contacts / separates, a movable rack is displaced relatively with respect to each clamping body. Accordingly, the marking means connected to the movable rack can be displaced relative to each of the sandwiching bodies as the pair of sandwiching bodies come in contact with and apart from each other.

以上の如く、本発明に係る樹木径測定器によれば、測定する樹木に対応して、マーキング手段をフレキシブルに位置決めすることができるため、測定する樹木の大きさに関わらず、マーキング手段が樹木に対して適切な位置に配置できるという優れた効果を奏する。   As described above, according to the tree diameter measuring instrument according to the present invention, the marking means can be flexibly positioned corresponding to the tree to be measured, so that the marking means can be used regardless of the size of the tree to be measured. There is an excellent effect that it can be arranged at an appropriate position.

以上より、本実施形態に係る樹木径測定器は、一対の挟み体１，２が接離する方向において、マーキング手段３が各挟み体１，２に対して相対的に変位するため、測定する樹木Ｘに対応して、マーキング手段３を位置決めできる。したがって、測定する樹木Ｘの大きさに関わらず、マーキング手段３が樹木Ｘに対して適切な位置に配置できる。   From the above, the tree diameter measuring instrument according to the present embodiment measures the marking means 3 because the marking means 3 is relatively displaced with respect to each of the sandwiching bodies 1 and 2 in the direction in which the pair of sandwiching bodies 1 and 2 are in contact with and away from each other. Corresponding to the tree X, the marking means 3 can be positioned. Therefore, regardless of the size of the tree X to be measured, the marking means 3 can be arranged at an appropriate position with respect to the tree X.

また、本実施形態に係る樹木径測定器は、各挟み体１，２とマーキング手段３とを接続する各弾性体４１が、一対の挟み体１，２が接離する方向に沿って伸縮するため、一対の挟み体１，２が接離するのに伴い、マーキング手段３を各挟み体１，２に対して相対的に変位できる。しかも、一対の挟み体１，２を操作することにより、マーキング手段３を個別に操作することなく、マーキング手段３を一対の挟み体１，２の間で位置決めさせることもできる。   Further, in the tree diameter measuring instrument according to the present embodiment, each elastic body 41 that connects each sandwich body 1, 2 and the marking means 3 expands and contracts along the direction in which the pair of sandwich bodies 1, 2 are in contact with and away from each other. Therefore, the marking means 3 can be displaced relative to each of the sandwiching bodies 1 and 2 as the pair of sandwiching bodies 1 and 2 come in contact with and separate from each other. In addition, by operating the pair of sandwiching bodies 1 and 2, the marking means 3 can be positioned between the pair of sandwiching bodies 1 and 2 without individually operating the marking means 3.

具体的には、図４（ａ）及び（ｂ）に示すように、第２挟み体２が第１挟み体１から離反するよう（Ｃ矢印方向）に移動すると、各弾性体４１が伸びるため、マーキング手段３が第１挟み体１から離反するよう（Ｄ矢印方向）に移動する。そして、各弾性体４１の伸びる量が等しいため、マーキング手段３は、第２挟み体２が移動する距離の半分の距離を移動することになる。   Specifically, as shown in FIGS. 4A and 4B, when the second sandwiching body 2 moves away from the first sandwiching body 1 (in the direction of arrow C), each elastic body 41 extends. The marking means 3 is moved away from the first sandwiching body 1 (in the direction of arrow D). And since the extension amount of each elastic body 41 is equal, the marking means 3 will move the half distance of the distance which the 2nd clamping body 2 moves.

このとき、マーキング手段３は、第２挟み体２から離反する距離と同じ距離を、第１挟み体１からも離反している。したがって、マーキング手段３は、一対の挟み体１，２が接離するのに伴って、各挟み体１，２に対して相対的に変位し、しかも、常に、一対の挟み体１，２の略中間に配置されることになる。   At this time, the marking means 3 is also separated from the first sandwiching body 1 by the same distance as the distance separating from the second sandwiching body 2. Therefore, the marking means 3 is relatively displaced with respect to each of the sandwiching bodies 1 and 2 as the pair of sandwiching bodies 1 and 2 are brought into contact with and separated from each other, and always the pair of sandwiching bodies 1 and 2. It will be arranged approximately in the middle.

また、本実施形態に係る樹木径測定器は、収容部３２が軸体３２ａを介して支持体３３に枢着されているため、一対のチョーク３１，３１の先端をそれぞれ樹木Ｘと対向させるべく、各チョーク３１の配置を切り替えることができる。   Further, in the tree diameter measuring instrument according to the present embodiment, since the housing portion 32 is pivotally attached to the support body 33 via the shaft body 32a, the ends of the pair of chokes 31, 31 should be opposed to the tree X, respectively. The arrangement of the chokes 31 can be switched.

具体的には、図５（ａ）を示すように、付勢体３２ｂに抗して、収容部３２を下方（Ｅ矢印方向）に向けて引くことにより、収容部３２を支持体３３から離反させる。これにより、収容部３２の被係合部３２ｃと支持体３３の係合部３３ａとの係合が解除されるため、その状態を維持しつつ、図５（ｂ）に示すように、収容部３２を軸体３２ａ周り（Ｆ矢印方向）に回動する。   Specifically, as shown in FIG. 5A, the accommodating portion 32 is separated from the support 33 by pulling the accommodating portion 32 downward (in the direction of arrow E) against the urging body 32b. Let Thereby, the engagement between the engaged portion 32c of the storage portion 32 and the engagement portion 33a of the support 33 is released, so that the storage portion is maintained as shown in FIG. 32 is rotated around the shaft body 32a (in the direction of arrow F).

そして、収容部３２を離すと、付勢体３２ｂにより、収容部３２が支持体３３に接近し、さらに、収容部３２の被係合部３２ｃが支持体３３の係合部３３ａに係合される。このように、一方のチョーク３１の先端が樹木Ｘに対向する状態から、他方のチョーク３１の先端が樹木Ｘに対向する状態に切り替えることができる。   When the accommodating portion 32 is released, the accommodating portion 32 approaches the support 33 by the urging body 32b, and the engaged portion 32c of the accommodating portion 32 is engaged with the engaging portion 33a of the support 33. The In this way, it is possible to switch from the state in which the tip of one choke 31 faces the tree X to the state in which the tip of the other choke 31 faces the tree X.

以上より、本実施形態に係る樹木径測定器は、一対の挟み体１，２０が接離する方向において、マーキング手段３０が各挟み体１，２０に対して相対的に変位するため、測定する樹木Ｘに対応して、マーキング手段３０を位置決めできる。したがって、測定する樹木Ｘの大きさに関わらず、マーキング手段３０が樹木Ｘに対して適切な位置に配置できる。   As described above, the tree diameter measuring instrument according to the present embodiment measures the marking means 30 because the marking means 30 is relatively displaced with respect to each of the sandwiching bodies 1 and 20 in the direction in which the pair of sandwiching bodies 1 and 20 contact and separate. Corresponding to the tree X, the marking means 30 can be positioned. Therefore, regardless of the size of the tree X to be measured, the marking means 30 can be arranged at an appropriate position with respect to the tree X.

また、本実施形態に係る樹木径測定器は、第２挟み体２０に固定（枢着）される歯車機構４４が、第１挟み体１に固定される固定ラック４２と噛合すると共に、各挟み体１，２０に対して相対的に変位可能な可動ラック４３と噛合する構成である。これにより、一対の挟み体１，２０が接離するのに伴い、歯車機構４４が回転するため、可動ラック４３が各挟み体１，２０に対して相対的に変位する。   In the tree diameter measuring instrument according to the present embodiment, the gear mechanism 44 fixed (pivotally attached) to the second sandwiching body 20 meshes with the fixed rack 42 fixed to the first sandwiching body 1, and each clamping It is configured to mesh with a movable rack 43 that can be displaced relative to the bodies 1 and 20. As a result, the gear mechanism 44 rotates as the pair of sandwiching bodies 1 and 20 come in contact with and away from each other, so that the movable rack 43 is displaced relative to each sandwiching body 1 and 20.

したがって、可動ラック４３に連結されるマーキング手段３０は、一対の挟み体１，２０が接離するのに伴い、各挟み体１，２０に対して相対的に変位することができる。しかも、一対の挟み体１，２０を操作することにより、マーキング手段３０を個別に操作することなく、マーキング手段３０を一対の挟み体１，２０の間で位置決めさせることもできる。   Therefore, the marking means 30 connected to the movable rack 43 can be relatively displaced with respect to each of the sandwiching bodies 1 and 20 as the pair of sandwiching bodies 1 and 20 come in contact with and separate from each other. Moreover, by operating the pair of sandwiching bodies 1, 20, the marking means 30 can be positioned between the pair of sandwiching bodies 1, 20 without operating the marking means 30 individually.

具体的には、図１０（ａ）及び（ｂ）に示すように、第２挟み体２０が第１挟み体１から離反するよう（Ｋ矢印方向）に移動すると、第１歯車４４ａが固定ラック４２と噛合し、上下方向を中心（Ｌ矢印方向）に回転する。そして、第２歯車４４ｂ（図１０において図示していない）が第１歯車４４ａと噛合するため、第１歯車４４ａと反対方向（Ｍ矢印方向）に回転すると共に、第３歯車４４ｃも第２歯車４４ｂと一体的になって回転する。   Specifically, as shown in FIGS. 10A and 10B, when the second sandwiching body 20 moves away from the first sandwiching body 1 (in the direction of the arrow K), the first gear 44a is fixed to the fixed rack. 42 and meshes with the vertical direction as the center (L arrow direction). Since the second gear 44b (not shown in FIG. 10) meshes with the first gear 44a, the second gear 44b rotates in the opposite direction (M arrow direction) to the first gear 44a, and the third gear 44c is also the second gear. Rotates integrally with 44b.

これにより、可動ラック４３が第３歯車４４ｃと噛合するため、第２挟み体２０が移動する方向と反対方向（Ｎ矢印方向）に移動する。このとき、第３歯車４４ｃが第２歯車４４ｂに対して半数の歯数であるため、可動ラック４３が第２挟み体２０から離反する距離は、第２挟み体２０が第１挟み体１から離反する距離の半分である。なお、可動ラック４３は、第１挟み体１に対しても、同じ距離を離反している。   Thereby, since the movable rack 43 meshes with the third gear 44c, it moves in the direction opposite to the direction in which the second sandwiching body 20 moves (in the direction of arrow N). At this time, since the third gear 44c has half the number of teeth with respect to the second gear 44b, the distance at which the movable rack 43 is separated from the second sandwiching body 20 is such that the second sandwiching body 20 is separated from the first sandwiching body 1. Half the distance away. In addition, the movable rack 43 is separated from the first sandwiching body 1 by the same distance.

したがって、可動ラック４３は、一対の挟み体１，２０が離反（接近）するのに伴って、一対の挟み体１，２０が離反（接近）する距離に対して、半分の距離を、各挟み体１，２０から離反（接近）する。これにより、可動ラック４３に連結されるマーキング手段３０は、一対の挟み体１，２０が接離するのに伴って、各挟み体１，２０に対して相対的に変位し、しかも、常に、一対の挟み体１，２０の略中間に配置されることになる。   Therefore, the movable rack 43 has a half distance between each pair of the sandwiching bodies 1 and 20 with respect to the distance that the pair of sandwiching bodies 1 and 20 separate (approach). Separate (approach) from the bodies 1 and 20. Thereby, the marking means 30 connected to the movable rack 43 is displaced relative to each of the sandwiching bodies 1 and 20 as the pair of sandwiching bodies 1 and 20 come into contact with and separated from each other. It will be arranged approximately in the middle of the pair of sandwiching bodies 1 and 20.

For example, the marking member may be a spray that sprays ink or the like, or may be a stamp that is imprinted with ink or the like.

また、上記実施形態に係る樹木径測定器においては、マーキング手段３（３０）がチョーク３１を二つ備える場合を説明したが、斯かる場合に限られない。例えば、マーキング手段がチョーク３１を一つ備える場合でもよく、また、チョーク３１を三つ以上備え、それぞれ切り替え可能に構成される場合でもよい。   Moreover, in the tree diameter measuring device which concerns on the said embodiment, although the case where the marking means 3 (30) was provided with two chalk 31 was demonstrated, it is not restricted to such a case. For example, the marking means may include one choke 31 or may include three or more chokes 31 that are configured to be switchable.

また、上記実施形態に係る樹木径測定器においては、移動手段４（４０）は、一対の挟み体１，２（２０）が接離するのに伴って、マーキング手段３（３０）を各挟み体１，２（２０）に対して相対的に変位する場合を説明したが、斯かる場合に限られない。例えば、移動手段は、各挟み体を接離する操作とは別に、マーキング手段を各挟み体に対して相対的に変位させる操作を行うような構成である場合でもよい。   Further, in the tree diameter measuring instrument according to the above embodiment, the moving means 4 (40) sandwiches the marking means 3 (30) as the pair of sandwiching bodies 1, 2 (20) come and go. Although the case where it displaced relatively with respect to the bodies 1 and 2 (20) was demonstrated, it is not restricted to such a case. For example, the moving means may be configured to perform an operation of displacing the marking means relative to each of the sandwiching bodies separately from the operation of contacting and separating each of the sandwiching bodies.

また、上記実施形態に係る樹木径測定器においては、移動手段４（４０）は、マーキング手段３（３０）を各挟み体１，２（２０）に対して相対的に変位させる場合を説明したが、斯かる場合に限られない。例えば、移動手段は、マーキング手段を一方の挟み体に対してのみ相対的に変位させる場合、即ち、他方の挟み体と一体的に形成される（他方の挟み体に固定される）場合でもよい。   Moreover, in the tree diameter measuring device which concerns on the said embodiment, the moving means 4 (40) demonstrated the case where the marking means 3 (30) was displaced relatively with respect to each clamping body 1 and 2 (20). However, it is not limited to such a case. For example, the moving means may be a case where the marking means is relatively displaced with respect to only one sandwiching body, that is, a case where the marking means is formed integrally with the other sandwiching body (fixed to the other sandwiching body). .

However, the present invention is not limited to such a case. For example, the fixed rack may be fixed to the second sandwiching body, and the gear mechanism may be pivotally attached (fixed) to the first sandwiching body. That is, the fixed rack may be formed integrally with the second sandwiching body, and the gear mechanism may be formed integrally with the first sandwiching body.

また、第２実施形態に係る樹木径測定器においては、歯車機構４４が三つの歯車４４ａ，４４ｂ，４４ｃを備える場合を説明したが、斯かる場合に限られない。例えば、歯車機構が歯車を一つ、二つ又は四つ以上備える場合でもよい。   Moreover, in the tree diameter measuring device which concerns on 2nd Embodiment, although the case where the gear mechanism 44 was provided with the three gears 44a, 44b, 44c was demonstrated, it is not restricted to such a case. For example, the gear mechanism may include one, two, or four or more gears.
