Description

特許法第３０条第２項適用申請有り 試験日 令和２年７月１３日 試験場所 大阪府富田林市桜井町１丁目１７－３０Patent Law Article 30, Paragraph 2 Application Applicable Test Date July 13, 2 Reiwa Test Location 1-17-30 Sakurai-cho, Tondabayashi-shi, Osaka

この発明は固定装置に関し、より特定的には、ランマを車両に載せて運搬するときに用いられる固定装置に関する。 The present invention relates to a fixing device, and more specifically to a fixing device used when carrying a rammer on a vehicle.

従来、締固めに用いられるランマは、トラックなどの車両の荷台に載せて運搬されることが多い。このとき、ランマの重心が上方にあるため、搬送時にランマを車両の荷台に倒して載せると、燃料供給路コックを閉じていても、燃料タンク内の燃料が燃料キャップの空気口から漏出するおそれがある。また、ランマを荷台に倒して載せるには広いスペースが必要である。一方、ランマを荷台に立てたまま載せて運搬する場合、ロープにて緊縛するには労力と時間とが必要であり、また、運搬中の振動によってロープが緩み、ランマが倒れるおそれがある。 Conventionally, a rammer used for compaction is often carried on a loading platform of a vehicle such as a truck. At this time, since the center of gravity of the rammer is above, if the rammer is tilted and placed on the loading platform of the vehicle during transportation, the fuel in the fuel tank may leak from the air port of the fuel cap even if the fuel supply path cock is closed. There is. In addition, a large space is required to lay the rammer on the loading platform. On the other hand, when the rammer is carried while standing on the loading platform, it takes labor and time to bind it with a rope, and the rope may loosen due to vibration during transportation, and the rammer may fall down.

そこで、特許文献１に示すようなランマ運搬用の支持金具が提案されている。この支持金具は、トラックの背板部の２ヶ所に設けられる鉤フックを含む。当該鉤フックをトラックの背板部に対し略直角に配置し、トラックの荷台にランマを立てたまま載せて、ランマのハンドルフレームが２つの鉤フックに掛かるようにランマを位置決めする。ランマの積み込みが完了すると、鉤フックを左右に押し広げてハンドルフレームの曲線部分に接触させ、ハンドルフレームが動かない事を確認する。その後、締め付け金具を締め付けることによって鉤フックを遊動しないように固定し、トラックの背板部にランマを固定する。 Therefore, a support metal fitting for transporting a rammer as shown in Patent Document 1 has been proposed. This support bracket includes hooks provided at two points on the back plate of the truck. The hook is placed at a substantially right angle to the back plate of the truck, and the rammer is placed upright on the truck bed, and the rammer is positioned so that the handle frame of the rammer hangs on the two hooks. When the loading of the rammer is completed, push the hook hook to the left and right to make contact with the curved part of the handle frame, and check that the handle frame does not move. After that, the hook is fixed so as not to move by tightening the tightening metal fitting, and the rammer is fixed to the back plate of the truck.

特開２００６－２９０５７号公報Japanese Unexamined Patent Publication No. 2006-29057

特許文献１の支持金具では、２箇所の鉤フックにランマのハンドルフレームを掛けるだけであるので、ランマが運搬中に不安定になり、荷台上で倒れるおそれがある。 In the support metal fitting of Patent Document 1, since the handle frame of the rammer is only hung on the two hooks, the rammer becomes unstable during transportation and may fall on the loading platform.

それゆえに、この発明の主たる目的は、ランマを倒すことなく円滑に運搬できる、固定装置を提供することである。 Therefore, a main object of the present invention is to provide a fixing device that can be smoothly transported without knocking down the rammer.

上述の目的を達成するために、原動機を有するランマ上部と、転圧板を有するランマ下部と、ランマ上部およびランマ下部を連結する伸縮可能な防振部材と、ランマ上部に接続されるハンドルとを備えるランマを立てた状態で固定するための固定装置であって、基板と、ハンドルを基板との間で保持しつつ下方に押圧するために立てた状態の基板に対して上下方向に揺動可能に基板に設けられる保持部と、保持部を基板に対して開閉させるために保持部の外面に一体的に設けられるレバー部と、基板と保持部との間でハンドルを保持した状態でレバー部の動きを規制するために基板に設けられるロック部とを備える、固定装置が提供される。 In order to achieve the above-mentioned object, the upper part of the rammer having the prime mover, the lower part of the rammer having the rolling compactor plate, the stretchable vibration isolator connecting the upper part of the rammer and the lower part of the rammer, and the handle connected to the upper part of the rammer are provided. It is a fixing device for fixing the rammer in an upright state, and can swing up and down with respect to the board in an upright state to press the handle downward while holding the board and the handle. A holding portion provided on the board, a lever portion integrally provided on the outer surface of the holding portion for opening and closing the holding portion with respect to the board, and a lever portion in a state where the handle is held between the board and the holding portion. A fixing device is provided that includes a locking portion provided on the substrate to regulate movement.

この発明では、ランマを車両の荷台に載せて運搬するとき、固定装置の基板が荷台前方のフレームに取り付けられる。このとき、基板は立てた状態で設けられる。基板の上下方向の位置は、基板と保持部との間でランマのハンドルを保持できる高さに設定される。つぎに、ランマのハンドルが基板および／または開いた状態の保持部に対向するように、ランマが立てられた状態で固定装置の手前まで運ばれる。その状態で、レバー部を操作して、保持部を基板に対して閉じるように下方に揺動させると、ランマのハンドルが基板と保持部との間で保持されるとともに押し下げられる。そして、ロック部によってレバー部の動きが規制され、その状態が維持される。このようにして、ランマは下方に押圧された状態で固定装置によって保持される。このとき、ランマのハンドルが基板と保持部との間で保持されるだけではなく、保持部によってランマ自体が下方に押圧されるので、ランマ自体の重量とも相俟って、ランマ上部とランマ下部とを連結する防振部材が圧縮され弾発力を有した状態で、ランマ下部が荷台の床面に強く押し付けられる。したがって、防振部材による緩衝機能が十分に働くとともに、ランマを上下から強く支持できるので、ランマの運搬中に荷台が揺れても、運搬中の振動を吸収できるとともに、ランマの荷台への固定状態を安定させることができ、ランマを倒すことなく円滑に運搬できる。 In the present invention, when the rammer is carried on the loading platform of the vehicle, the substrate of the fixing device is attached to the frame in front of the loading platform. At this time, the substrate is provided in an upright position. The vertical position of the board is set to a height at which the handle of the rammer can be held between the board and the holding portion. Next, the rammer is brought upright to the front of the fixing device so that the handle of the rammer faces the substrate and / or the holding portion in the open state. In that state, when the lever portion is operated to swing the holding portion downward so as to close the holding portion, the handle of the rammer is held and pushed down between the substrate and the holding portion. Then, the movement of the lever portion is restricted by the lock portion, and the state is maintained. In this way, the rammer is held by the fixing device in a downwardly pressed state. At this time, not only the handle of the rammer is held between the board and the holding portion, but also the rammer itself is pressed downward by the holding portion. The lower part of the rammer is strongly pressed against the floor surface of the loading platform in a state where the anti-vibration member connecting the two is compressed and has elastic force. Therefore, the cushioning function of the anti-vibration member works sufficiently, and the rammer can be strongly supported from above and below. Therefore, even if the loading platform shakes during transportation of the rammer, the vibration during transportation can be absorbed and the rammer is fixed to the loading platform. Can be stabilized and can be transported smoothly without defeating the rammer.

好ましくは、保持部は、断面Ｖ字状に折り曲げられた板状部材からなる。この場合、保持部によって、ランマのハンドルを横方向の広い範囲でより安定して保持できる。また、固定装置の基板に対してランマのハンドルを位置決めするとき、ハンドルに多少の位置ずれがあっても、保持部を下方へ揺動させて閉じるときに、ハンドルの位置ずれを修正できる。したがって、固定装置によるランマの固定作業が容易になり、固定作業時間を短くできる。 Preferably, the holding portion is made of a plate-shaped member bent in a V-shaped cross section. In this case, the holding portion allows the handle of the rammer to be held more stably in a wide range in the lateral direction. Further, even if the handle of the rammer is positioned with respect to the substrate of the fixing device, even if the handle is slightly misaligned, the misalignment of the handle can be corrected when the holding portion is swung downward to close. Therefore, the fixing work of the rammer by the fixing device becomes easy, and the fixing work time can be shortened.

また好ましくは、基板が取り付けられる枠状部材をさらに含む。この場合、固定装置の基板を車両の荷台前方のフレームに取り付けるとき、枠状部材をフレームに固定することによって、基板を間接的にフレームに取り付けることができる。すなわち、枠状部材を介することで、基板を荷台前方に容易に配置することができる。 Further preferably, a frame-shaped member to which the substrate is attached is further included. In this case, when the substrate of the fixing device is attached to the frame in front of the loading platform of the vehicle, the substrate can be indirectly attached to the frame by fixing the frame-shaped member to the frame. That is, the substrate can be easily arranged in front of the loading platform via the frame-shaped member.

さらに好ましくは、ロック部は、バネカンを含む。この場合、バネカンによって、レバー部の動きを容易に規制できるとともに、運搬中の荷台の振動を吸収できる。 More preferably, the lock portion includes a spring can. In this case, the spring can easily regulates the movement of the lever portion and can absorb the vibration of the loading platform during transportation.

好ましくは、基板および保持部のそれぞれの内面に設けられる弾性部材をさらに含む。この場合、基板に設けられた弾性部材と保持部に設けられた弾性部材とによって、ハンドルを強固に保持できる。また、これらの弾性部材においても運搬中の荷台の振動を吸収できる。 Preferably, an elastic member provided on the inner surface of each of the substrate and the holding portion is further included. In this case, the handle can be firmly held by the elastic member provided on the substrate and the elastic member provided on the holding portion. Further, these elastic members can also absorb the vibration of the loading platform during transportation.

なお、ランマや基板を「立てた状態」とは、垂直に立設する場合に限定されず、傾いていてもよい。 The "standing state" of the rammer or the substrate is not limited to the case where the rammer or the substrate is erected vertically, and may be tilted.

この発明によれば、ランマを倒すことなく円滑に運搬できる。 According to the present invention, the rammer can be smoothly transported without being knocked down.

以下、図面を参照してこの発明の実施の形態について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１～図３を参照して、この発明の一実施形態に係る固定装置１０は、ランマ１００（後述）を固定するために用いられ、枠状部材１２を含む。枠状部材１２は、上下方向に間隔をあけて対向する一対の細長い板状部１４ａ，１４ｂと、左右方向に間隔をあけて対向する一対の棒状部１６ａ，１６ｂとを含む。板状部１４ａ，１４ｂの一端部は、棒状部１６ａによって連結され、板状部１４ａ，１４ｂの他端部は、棒状部１６ｂによって連結され、枠状部材１２は、略長方形状に形成される。板状部１４ａの両端部近傍にはそれぞれ、取付用の貫通孔１４ｃが設けられ、板状部１４ｂの両端部近傍にはそれぞれ、取付用の貫通孔１４ｄが設けられる。 With reference to FIGS. 1 to 3, the fixing device 10 according to the embodiment of the present invention is used for fixing the rammer 100 (described later), and includes a frame-shaped member 12. The frame-shaped member 12 includes a pair of elongated plate-shaped portions 14a and 14b facing each other at intervals in the vertical direction, and a pair of rod-shaped portions 16a and 16b facing each other at intervals in the left-right direction. One end of the plate-shaped portions 14a and 14b is connected by the rod-shaped portion 16a, the other end of the plate-shaped portions 14a and 14b is connected by the rod-shaped portion 16b, and the frame-shaped member 12 is formed in a substantially rectangular shape. .. Through holes 14c for mounting are provided in the vicinity of both ends of the plate-shaped portion 14a, and through holes 14d for mounting are provided in the vicinity of both ends of the plate-shaped portion 14b, respectively.

棒状部１６ａ，１６ｂにはそれぞれ、パイプ状の取付部１８ａ，１８ｂが嵌められる。すなわち、取付部１８ａ，１８ｂにはそれぞれ、棒状部１６ａ，１６ｂが挿通される。取付部１８ａ，１８ｂはそれぞれ、棒状部１６ａ，１６ｂに対して上下方向に摺動可能である。取付部１８ａ，１８ｂはそれぞれ、その側面から内部まで貫通したねじ孔２０ａ，２０ｂを含み、ねじ孔２０ａ，２０ｂに調整ねじ２２ａ，２２ｂを螺入して棒状部１６ａ，１６ｂの外周面に当接させることによって、取付部１８ａ，１８ｂを所望の位置に固定できる。 Pipe-shaped mounting portions 18a and 18b are fitted to the rod-shaped portions 16a and 16b, respectively. That is, rod-shaped portions 16a and 16b are inserted into the mounting portions 18a and 18b, respectively. The mounting portions 18a and 18b are slidable in the vertical direction with respect to the rod-shaped portions 16a and 16b, respectively. The mounting portions 18a and 18b include screw holes 20a and 20b penetrating from the side surface to the inside, respectively, and the adjusting screws 22a and 22b are screwed into the screw holes 20a and 20b to abut on the outer peripheral surfaces of the rod-shaped portions 16a and 16b. By doing so, the mounting portions 18a and 18b can be fixed at a desired position.

このような棒状部１６ａ，１６ｂには、基板２４が取り付けられる。すなわち、枠状部材１２には、棒状部１６ａ，１６ｂを介して基板２４が取り付けられる。基板２４は、略Ｌ字状の板状部材からなり、主板部２４ａと副板部２４ｂとを含む。主板部２４ａは、長方形状に形成され、その幅は、棒状部１６ａ，１６ｂの間隔と略等しい。副板部２４ｂは、短冊状に形成され、主板部２４ａの一端部（この実施形態では、左端部）近傍から下方かつ直角方向に延びるように設けられる。副板部２４ｂには、２つの貫通孔２４ｃが形成される。この実施形態では、主板部２４ａの両端部がそれぞれ取付部１８ａ，１８ｂに取り付けられる。したがって、取付部１８ａ，１８ｂの上下方向の摺動に伴って、基板２４を上下方向に移動でき、その高さを調整できる。 A substrate 24 is attached to such rod-shaped portions 16a and 16b. That is, the substrate 24 is attached to the frame-shaped member 12 via the rod-shaped portions 16a and 16b. The substrate 24 is composed of a substantially L-shaped plate-shaped member, and includes a main plate portion 24a and a sub plate portion 24b. The main plate portion 24a is formed in a rectangular shape, and its width is substantially equal to the distance between the rod-shaped portions 16a and 16b. The sub-plate portion 24b is formed in a strip shape, and is provided so as to extend downward and in a right-angled direction from the vicinity of one end portion (in this embodiment, the left end portion) of the main plate portion 24a. Two through holes 24c are formed in the sub-plate portion 24b. In this embodiment, both ends of the main plate portion 24a are attached to the attachment portions 18a and 18b, respectively. Therefore, the substrate 24 can be moved in the vertical direction as the mounting portions 18a and 18b slide in the vertical direction, and the height thereof can be adjusted.

基板２４の主板部２４ａにおける他端部（この実施形態では、右端部）側上端部には、保持部２６が２つの蝶番２８を介して、立てた状態の基板２４に対して上下方向に揺動可能に設けられる。保持部２６は、断面Ｖ字状に折り曲げられた板状部材からなり、すなわち切妻状に形成され、横方向に延びるように配置される。保持部２６は、ランマ１００のハンドル１１２（後述）を、上方から下方に押圧しながら基板２４との間で保持可能である。 At the upper end of the main plate portion 24a of the substrate 24 on the other end (right end portion in this embodiment) side, the holding portion 26 swings up and down with respect to the upright substrate 24 via two hinges 28. It is provided so that it can be moved. The holding portion 26 is made of a plate-shaped member bent in a V-shaped cross section, that is, is formed in a gable shape and is arranged so as to extend in the lateral direction. The holding portion 26 can hold the handle 112 (described later) of the rammer 100 between the rammer 100 and the substrate 24 while pressing the handle 112 (described later) from above to below.

基板２４のうちハンドル１１２を保持する部分には、弾性部材３０ａが設けられ、保持部２６の内面には、２つの弾性部材３０ｂ，３０ｃが設けられる。弾性部材３０ａ～３０ｃは、たとえば略同寸法の長方形状のゴムシートからなる。 An elastic member 30a is provided on the portion of the substrate 24 that holds the handle 112, and two elastic members 30b and 30c are provided on the inner surface of the holding portion 26. The elastic members 30a to 30c are made of, for example, rectangular rubber sheets having substantially the same dimensions.

保持部２６を基板２４に対して開閉させるために、保持部２６の外面にはレバー部３２が一体的に取り付けられる。レバー部３２は、軸部３２ａと、板状部３２ｂと、ハンドル部３２ｃとを含む。軸部３２ａは、横方向に延び、保持部２６のうち蝶番２８に近い側の外面に取り付けられる。軸部３２ａの長さは、一対の棒状部１６ａ，１６ｂの間隔よりやや小さく設定される。これにより、軸部３２ａは、２つの蝶番２８を支軸として、棒状部１６ａ，１６ｂに接触することなく揺動でき、それに伴って保持部２６を上下方向に揺動させることができる。板状部３２ｂは、軸部３２ａの一端部（この実施形態では、左側端部）に、棒状部３２に対して直角方向に延びるように設けられる。板状部３２ｂは、その先端部中央に切欠３２ｄを有する。ハンドル部３２ｃは、棒状に形成され、板状部３２ｂの一側部（この実施形態では、左側部）に設けられる。 In order to open and close the holding portion 26 with respect to the substrate 24, a lever portion 32 is integrally attached to the outer surface of the holding portion 26. The lever portion 32 includes a shaft portion 32a, a plate-shaped portion 32b, and a handle portion 32c. The shaft portion 32a extends laterally and is attached to the outer surface of the holding portion 26 on the side closer to the hinge 28. The length of the shaft portion 32a is set to be slightly smaller than the distance between the pair of rod-shaped portions 16a and 16b. As a result, the shaft portion 32a can swing with the two hinges 28 as support shafts without contacting the rod-shaped portions 16a and 16b, and the holding portion 26 can swing in the vertical direction accordingly. The plate-shaped portion 32b is provided at one end of the shaft portion 32a (in this embodiment, the left end portion) so as to extend in a direction perpendicular to the rod-shaped portion 32. The plate-shaped portion 32b has a notch 32d in the center of the tip portion thereof. The handle portion 32c is formed in a rod shape and is provided on one side portion (in this embodiment, the left side portion) of the plate-shaped portion 32b.

枠状部１２とハンドル部３２ｃとは、ゴムチューブ３４によって連結される。ゴムチューブ３４は、枠状部１２の板状部１４ａと棒状部１６ａとの接続箇所に掛けられるとともに、ハンドル部３２ｃに掛けられる。ハンドル部３２ｃに力を加えていない状態では、ゴムチューブ３４によってハンドル部３２ｃは図１に示すように位置し、保持部２６は開かれる。なお、図２、図３、後述する図７および図１０では、ゴムチューブ３４の図示は省略されている。 The frame-shaped portion 12 and the handle portion 32c are connected by a rubber tube 34. The rubber tube 34 is hung on the connection portion between the plate-shaped portion 14a and the rod-shaped portion 16a of the frame-shaped portion 12, and is also hung on the handle portion 32c. When no force is applied to the handle portion 32c, the rubber tube 34 positions the handle portion 32c as shown in FIG. 1, and the holding portion 26 is opened. Note that the rubber tube 34 is not shown in FIGS. 2, 3 and 7 and 10 described later.

また、基板２４と保持部２６との間でハンドル１１２を保持した状態でレバー部３２の動きを規制するために、基板２４にロック部としての座付きバネカン３６が設けられる。座付きバネカン３６は、座部３８と、バネカン４０とを含む。 Further, in order to restrict the movement of the lever portion 32 while the handle 112 is held between the substrate 24 and the holding portion 26, the substrate 24 is provided with a seated spring can 36 as a locking portion. The seated spring can 36 includes a seat 38 and a spring can 40.

図４および図５をも参照して、座部３８は、略短冊状の座部本体３８ａと、座部本体３８ａの上端部近傍に設けられる略Ｌ字状の係止片３８ｂと、座部本体３８ａの下端部近傍に設けられる一対の立設部３８ｃとを有する。座部本体３８ａには、２つの貫通孔３８ｄが形成され、一対の立設部３８ｃにはそれぞれ、貫通孔３８ｅが形成される。座部３８は、貫通孔３８ｄが副板部２４ｂの対応する貫通孔２４ｃに合うように位置決めされ、ボルト４２ａとナット４２ｂとによって、基板２４に固定される。バネカン４０は、レバー部４４と、押さえ部４６とを含む。 With reference to FIGS. 4 and 5, the seat portion 38 includes a substantially strip-shaped seat portion main body 38a, a substantially L-shaped locking piece 38b provided near the upper end portion of the seat portion main body 38a, and a seat portion. It has a pair of upright portions 38c provided near the lower end portion of the main body 38a. Two through holes 38d are formed in the seat body 38a, and through holes 38e are formed in each of the pair of upright portions 38c. The seat portion 38 is positioned so that the through hole 38d is aligned with the corresponding through hole 24c of the sub plate portion 24b, and is fixed to the substrate 24 by the bolt 42a and the nut 42b. The spring can 40 includes a lever portion 44 and a pressing portion 46.

レバー部４４は、レバー本体４４ａを含む。レバー本体４４ａには、幅方向に貫通する２つの貫通孔４４ｂ，４４ｃが形成される。一対の立設部３８ｃの間にレバー本体４４ａの端部を挟んだ状態で、連結棒４８が、立設部３８ｃの貫通孔３８ｅおよびレバー本体４４ａの貫通孔４４ｂに挿通され、かつ一対の立設部３８ｃを連結する。これによって、レバー部４４が座部３８に対して揺動可能に接続される。 The lever portion 44 includes a lever body 44a. Two through holes 44b and 44c penetrating in the width direction are formed in the lever body 44a.

このような固定装置１０の主要動作について説明する。 The main operation of such a fixing device 10 will be described.

図１、図５および図８（ａ）を参照して、まず、レバー部３２のハンドル部３２ｃを把持し、座部３８の係止片３８ｂが板状部３２ｂの切欠３２ｄ内に位置するまで、ハンドル部３２ｃを下方に揺動させる。ついで、図６、図７および図８（ａ）,（ｂ）を参照して、バネカン４０の係合部４６ｂの環状部４６ｇを、座部３８の係止片３８ｂに係合させ、基板２４と押さえ部４６とによって板状部３２ｂを挟む。その状態で、レバー部４４を下方に揺動させる。このとき、保持部４６ａおよび係合部４６ｂが引き下ろされ、係合部４６ｂは係止部３８ｂを下方に押圧しつつ係止部４０ｂに係止される。すると、レバー部３２および保持部２６が固定される。 With reference to FIGS. 1, 5 and 8 (a), first, the handle portion 32c of the lever portion 32 is gripped until the locking piece 38b of the seat portion 38 is located in the notch 32d of the plate-shaped portion 32b. , The handle portion 32c is swung downward. Then, referring to FIGS. 6, 7 and 8 (a) and 8 (b), the annular portion 46 g of the engaging portion 46b of the spring can 40 is engaged with the locking piece 38b of the seat portion 38, and the substrate 24 is engaged. The plate-shaped portion 32b is sandwiched between the holding portion 46 and the holding portion 46. In that state, the lever portion 44 is swung downward. At this time, the holding portion 46a and the engaging portion 46b are pulled down, and the engaging portion 46b is locked to the locking portion 40b while pressing the locking portion 38b downward. Then, the lever portion 32 and the holding portion 26 are fixed.

図９および図１０を参照して、このような固定装置１０は、トラック（軽トラックを含む）などの車両１によってランマ１００を立てた状態で運搬するときに好適に用いられる。ランマ１００は、原動機としてのエンジン１０２を有するランマ上部１０４と、転圧板１０６を有するランマ下部１０８と、ランマ上部１０４およびランマ下部１０８を連結する蛇腹状の伸縮可能な防振部材１１０と、ランマ上部１０４に接続されるハンドル１１２とを備える。 With reference to FIGS. 9 and 10, such a fixing device 10 is suitably used when the rammer 100 is transported in an upright state by a vehicle 1 such as a truck (including a light truck). The rammer 100 includes a rammer upper part 104 having an engine 102 as a prime mover, a rammer lower part 108 having a rolling compactor plate 106, a bellows-shaped expandable and contractible anti-vibration member 110 connecting the rammer upper part 104 and the rammer lower part 108, and a rammer upper part. It includes a handle 112 connected to 104.

固定装置１０によれば、ランマ１００を車両１の荷台２に載せて運搬するとき、固定装置１０の基板２４が荷台２の前方のフレーム３に取り付けられる。この実施形態では、枠状部材１２の２つの貫通孔１４ｃおよび２つの貫通孔１４ｄに対応する４つの孔５１がフレーム３に設けられ、貫通孔１４ｃ，１４ｄと対応する孔５１とが合うようにフレーム３に対して枠状部材１２が位置決めされて、ボルト５２を用いて固定装置１０の枠状部材１２がフレーム３に取り付けられる。このようにして、基板２４は、枠状部材１２を介してフレーム３に取り付けられ、立てた状態で設けられる。基板２４の上下方向の位置は、基板２４と保持部２６との間でランマ１００のハンドル１１２の横方向に延びる前部１１２ａを保持できる高さに設定される。つぎに、ハンドル１１２の前部１１２ａが基板２４および／または開いた状態の保持部２６に対向するように、ランマ１００が立てられた状態で固定装置１０の手前まで運ばれる。その状態で、レバー部３２を操作して、保持部２６を基板２４に対して閉じるように下方に揺動させると、ハンドル１１２の前部１１２ａが基板２４と保持部２６との間で保持されるとともに押し下げられる。そして、ロック部としての座付きバネカン３６によってレバー部３２の動きが規制され、その状態が維持される。このようにして、ランマ１００は下方に押圧された状態で固定装置１０によって保持される。このとき、ランマ１００のハンドル１１２の前部１１２ａが基板２４と保持部２６との間で保持されるだけではなく、保持部２６によってランマ１００自体が下方に押圧されるので、ランマ１００自体の重量とも相俟って、ランマ上部１０４とランマ下部１０８とを連結する防振部材１１０が圧縮され弾発力を有した状態で、ランマ下部１０８が荷台２の床面２ａに強く押し付けられる。したがって、防振部材１１０による緩衝機能が十分に働くとともに、ランマ１００を上下から強く支持できるので、ランマ１００の運搬中に荷台２が揺れても、運搬中の振動を吸収できるとともに、ランマ１００の荷台２への固定状態を安定させることができ、ランマ１００を倒すことなく円滑に運搬できる。また、ランマ１００の防振部材１１０は伸縮可能であるので、固定装置１０に対するハンドル１１２の位置が上下方向に多少ずれていても、そのずれを吸収して固定装置１０によってランマ１００を円滑に保持できる。 According to the fixing device 10, when the rammer 100 is placed on the loading platform 2 of the vehicle 1 and transported, the substrate 24 of the fixing device 10 is attached to the frame 3 in front of the loading platform 2. In this embodiment, the frame 3 is provided with four holes 51 corresponding to the two through holes 14c and the two through holes 14d of the frame-shaped member 12, so that the through holes 14c and 14d and the corresponding holes 51 are aligned with each other. The frame-shaped member 12 is positioned with respect to the frame 3, and the frame-shaped member 12 of the fixing device 10 is attached to the frame 3 by using the bolt 52. In this way, the substrate 24 is attached to the frame 3 via the frame-shaped member 12 and is provided in an upright state. The vertical position of the substrate 24 is set to a height at which the laterally extending front portion 112a of the handle 112 of the rammer 100 can be held between the substrate 24 and the holding portion 26. Next, the rammer 100 is carried upright to the front of the fixing device 10 so that the front portion 112a of the handle 112 faces the substrate 24 and / or the holding portion 26 in the open state. In that state, when the lever portion 32 is operated to swing the holding portion 26 downward so as to close the holding portion 26 with respect to the substrate 24, the front portion 112a of the handle 112 is held between the substrate 24 and the holding portion 26. It is pushed down with the lever. Then, the movement of the lever portion 32 is restricted by the seated spring can 36 as the lock portion, and the state is maintained. In this way, the rammer 100 is held by the fixing device 10 in a state of being pressed downward. At this time, not only the front portion 112a of the handle 112 of the rammer 100 is held between the substrate 24 and the holding portion 26, but also the rammer 100 itself is pressed downward by the holding portion 26, so that the weight of the rammer 100 itself is heavy. Together with this, the rammer lower portion 108 is strongly pressed against the floor surface 2a of the loading platform 2 in a state where the vibration-proof member 110 connecting the rammer upper portion 104 and the rammer lower portion 108 is compressed and has elastic force. Therefore, since the cushioning function of the anti-vibration member 110 works sufficiently and the rammer 100 can be strongly supported from above and below, even if the loading platform 2 shakes during transportation of the rammer 100, the vibration during transportation can be absorbed and the rammer 100 can be supported. The fixed state to the loading platform 2 can be stabilized, and the rammer 100 can be smoothly transported without being knocked down. Further, since the anti-vibration member 110 of the rammer 100 can be expanded and contracted, even if the position of the handle 112 with respect to the fixing device 10 is slightly displaced in the vertical direction, the displacement is absorbed and the rammer 100 is smoothly held by the fixing device 10. can.

保持部２６は、断面Ｖ字状に折り曲げられた切妻状の板状部材からなるので、保持部２６によって、ランマ１００のハンドル１１２の前部１１２ａを横方向の広い範囲でより安定して保持できる。また、固定装置１０の基板２４に対してハンドル１１２の前部１１２ａを位置決めするとき、ハンドル１１２の前部１１２ａに多少の位置ずれがあっても、保持部２６を下方へ揺動させて閉じるときに、ハンドル１１２の前部１１２ａの位置ずれを修正できる。したがって、固定装置１０によるランマ１００の固定作業が容易になり、作業時間を短くきる。 Since the holding portion 26 is composed of a gable-shaped plate-shaped member bent into a V-shaped cross section, the holding portion 26 can more stably hold the front portion 112a of the handle 112 of the rammer 100 in a wide range in the lateral direction. .. Further, when the front portion 112a of the handle 112 is positioned with respect to the substrate 24 of the fixing device 10, even if the front portion 112a of the handle 112 is slightly displaced, the holding portion 26 is swung downward to close. In addition, the misalignment of the front portion 112a of the handle 112 can be corrected. Therefore, the fixing work of the rammer 100 by the fixing device 10 becomes easy, and the working time can be shortened.

固定装置１０の基板２４を車両１の荷台２の前方のフレーム３に取り付けるとき、枠状部材１２をフレーム３に固定することによって、基板２４を間接的にフレーム３に取り付けることができる。すなわち、枠状部材１２を介することで、基板２４を荷台２の前方に容易に配置することができる。 When the substrate 24 of the fixing device 10 is attached to the frame 3 in front of the loading platform 2 of the vehicle 1, the substrate 24 can be indirectly attached to the frame 3 by fixing the frame-shaped member 12 to the frame 3. That is, the substrate 24 can be easily arranged in front of the loading platform 2 via the frame-shaped member 12.

バネカン４０によって、レバー部３２の動きを容易に規制できるとともに、運搬中の荷台２の振動を吸収できる。 The spring can 40 can easily regulate the movement of the lever portion 32 and can absorb the vibration of the loading platform 2 during transportation.

基板２４に設けられた弾性部材３０ａと保持部２６に設けられた弾性部材３０ｂ，３０ｃとによって、ハンドル１１２を強固に保持できる。また、これらの弾性部材３０ａ，３０ｂ，３０ｃにおいても運搬中の荷台２の振動を吸収できる。 The handle 112 can be firmly held by the elastic members 30a provided on the substrate 24 and the elastic members 30b and 30c provided on the holding portion 26. Further, these elastic members 30a, 30b, and 30c can also absorb the vibration of the loading platform 2 during transportation.

なお、上述の実施形態では、ゴムチューブ３４は、枠状部１２の板状部１４ａと棒状部１６ａとの接続箇所に掛けられるとともに、ハンドル部３２ｃに掛けられたが、これに限定されない。たとえば、図２に示すように、棒状部１６ａおよびハンドル部３２ｃのそれぞれにＵ字状のフック５４を設け、これらのフック５４にゴムチューブ３４を取り付けてもよい。また、ゴムチューブ３４と同様の機能を有する部材として、軸部３２ａに巻き付けられたばね部材が用いられてもよい。この場合、ゴムチューブ３４は必ずしも必要ではない。 In the above-described embodiment, the rubber tube 34 is hung on the connection portion between the plate-shaped portion 14a and the rod-shaped portion 16a of the frame-shaped portion 12 and is hung on the handle portion 32c, but the present invention is not limited thereto. For example, as shown in FIG. 2, a U-shaped hook 54 may be provided on each of the rod-shaped portion 16a and the handle portion 32c, and a rubber tube 34 may be attached to these hooks 54. Further, as a member having the same function as the rubber tube 34, a spring member wound around the shaft portion 32a may be used. In this case, the rubber tube 34 is not always necessary.

図１に示すように、さらに、保持部２６の外面にＵ字状のフック５５ａを設け、基板２４にワイヤ５５ｂを介してフック金具５５ｃを取り付けてもよい。フック金具５５ｃは、ばねによるロック機構を有する。この場合、図６に示すように、保持部２６を基板２４に対して閉じた状態で、フック金具５５ｃをフック５５ａに掛けることによって、ランマ１００のハンドル１１２を基板２４と保持部２６との間でより確実に保持できる。 As shown in FIG. 1, a U-shaped hook 55a may be further provided on the outer surface of the holding portion 26, and the hook metal fitting 55c may be attached to the substrate 24 via the wire 55b. The hook metal fitting 55c has a locking mechanism by a spring. In this case, as shown in FIG. 6, the handle 112 of the rammer 100 is placed between the substrate 24 and the holding portion 26 by hooking the hook metal fitting 55c to the hook 55a in a state where the holding portion 26 is closed with respect to the substrate 24. Can be held more reliably with.

上述の実施形態では、断面Ｖ字状をした板状の保持部２６が用いられたが、これに限定されない。それに代えて、一部が開いたリング状（たとえばＣ字状）の保持部が１つまたは２つ以上用いられてもよい。 In the above-described embodiment, the plate-shaped holding portion 26 having a V-shaped cross section is used, but the present invention is not limited to this. Alternatively, one or more ring-shaped (eg, C-shaped) holdings that are partially open may be used.

上述の実施形態では、ロック部として座付きバネカン３６が用いられたが、これに限定されない。ロック部は、基板２４と保持部２６との間でハンドル１１２を保持した状態でレバー部３２の動きを規制可能な任意の手段を用いることができる。 In the above-described embodiment, the spring can 36 with a seat is used as the lock portion, but the present invention is not limited to this. As the lock portion, any means capable of restricting the movement of the lever portion 32 while holding the handle 112 between the substrate 24 and the holding portion 26 can be used.

上述の実施形態では、枠状部材１２が車両１のフレーム３に直接取り付けられたが、これに限定されない。たとえば、枠状部材１２とフレームとの寸法の関係上、枠状部材１２をフレームに取り付けることが困難な場合には、図９に示す２本の細長い板状のステー５６がフレームに取り付けられ、これらのステー５６に枠状部材１２が取り付けられてもよい。また、枠状部材１２を用いることなく、基板２４が車両のフレームに直接取り付けられてもよい。さらに、固定装置１０は、車両のフレーム以外の箇所に取り付けられてもよい。 In the above embodiment, the frame-shaped member 12 is directly attached to the frame 3 of the vehicle 1, but the present invention is not limited to this. For example, when it is difficult to attach the frame-shaped member 12 to the frame due to the dimensional relationship between the frame-shaped member 12 and the frame, the two elongated plate-shaped stays 56 shown in FIG. 9 are attached to the frame. The frame-shaped member 12 may be attached to these stays 56. Further, the substrate 24 may be directly attached to the frame of the vehicle without using the frame-shaped member 12. Further, the fixing device 10 may be attached to a place other than the frame of the vehicle.

上述の実施形態では、パイプ状の取付部１８ａ，１８ｂはそれぞれ、１つのねじ孔２０ａ，２０ｂを含み、ねじ孔２０ａ，２０ｂに調整ねじ２２ａ，２２ｂを螺入可能に構成されたが、これに限定されない。当該取付部はさらに長く形成され、２つ以上のねじ孔を有し、各ねじ孔に調整ねじを螺入可能に構成されてもよい。 In the above-described embodiment, the pipe-shaped mounting portions 18a and 18b include one screw hole 20a and 20b, respectively, and the adjusting screws 22a and 22b can be screwed into the screw holes 20a and 20b.

この発明はランマの車両運搬用固定装置に関し、より特定的には、ランマを車両に載せて運搬するときに用いられるランマの車両運搬用固定装置に関する。 The present invention relates to a vehicle transport fixing device for a rammer, and more specifically to a vehicle transport fixing device for a rammer used when the rammer is mounted on a vehicle and transported.

従来、締固めに用いられるランマは、トラックなどの車両の荷台に載せて運搬されることが多い。このとき、ランマの重心が上方にあるため、搬送時にランマを車両の荷台に倒して載せると、燃料供給路コックを閉じていても、燃料タンク内の燃料が燃料キャップの空気口から漏出するおそれがある。また、ランマを荷台に倒して載せるには広いスペースが必要である。一方、ランマを荷台に立てたまま載せて運搬する場合、ロープにて緊縛するには労力と時間とが必要であり、また、運搬中の振動によってロープが緩み、ランマが倒れるおそれがある。 Conventionally, a rammer used for compaction is often carried on a loading platform of a vehicle such as a truck. At this time, since the center of gravity of the rammer is above, if the rammer is tilted and placed on the loading platform of the vehicle during transportation, the fuel in the fuel tank may leak from the air port of the fuel cap even if the fuel supply path cock is closed. There is. In addition, a large space is required to lay the rammer on the loading platform. On the other hand, when the rammer is carried while standing on the loading platform, it takes labor and time to bind it with a rope, and the rope may loosen due to vibration during transportation, and the rammer may fall down.

そこで、特許文献１に示すようなランマ運搬用の支持金具が提案されている。この支持金具は、トラックの背板部の２ヶ所に設けられる鉤フックを含む。当該鉤フックをトラックの背板部に対し略直角に配置し、トラックの荷台にランマを立てたまま載せて、ランマのハンドルフレームが２つの鉤フックに掛かるようにランマを位置決めする。ランマの積み込みが完了すると、鉤フックを左右に押し広げてハンドルフレームの曲線部分に接触させ、ハンドルフレームが動かない事を確認する。その後、締め付け金具を締め付けることによって鉤フックを遊動しないように固定し、トラックの背板部にランマを固定する。 Therefore, a support metal fitting for transporting a rammer as shown in Patent Document 1 has been proposed. This support bracket includes hooks provided at two points on the back plate of the truck. The hook is placed at a substantially right angle to the back plate of the truck, and the rammer is placed upright on the truck bed, and the rammer is positioned so that the handle frame of the rammer hangs on the two hooks. When the loading of the rammer is completed, push the hook hook to the left and right to make contact with the curved part of the handle frame, and check that the handle frame does not move. After that, the hook is fixed so as not to move by tightening the tightening metal fitting, and the rammer is fixed to the back plate of the truck.

特開２００６－２９０５７号公報Japanese Unexamined Patent Publication No. 2006-29057

特許文献１の支持金具では、２箇所の鉤フックにランマのハンドルフレームを掛けるだけであるので、ランマが運搬中に不安定になり、荷台上で倒れるおそれがある。 In the support metal fitting of Patent Document 1, since the handle frame of the rammer is only hung on the two hooks, the rammer becomes unstable during transportation and may fall on the loading platform.

それゆえに、この発明の主たる目的は、ランマを倒すことなく円滑に運搬できる、ランマの車両運搬用固定装置を提供することである。 Therefore, a main object of the present invention is to provide a vehicle transport fixing device for a rammer that can be smoothly transported without defeating the rammer.

上述の目的を達成するために、原動機を有するランマ上部と、転圧板を有するランマ下部と、ランマ上部およびランマ下部を連結する伸縮可能な防振部材と、ランマ上部に接続されるハンドルとを備えるランマを立てた状態で固定するためのランマの車両運搬用固定装置であって、基板と、ハンドルを基板との間で保持しつつ下方に押圧するために立てた状態の基板に対して上下方向に揺動可能に基板に設けられる保持部と、保持部を基板に対して開閉させるために保持部の外面に一体的に設けられるレバー部と、基板と保持部との間でハンドルを保持した状態でレバー部の動きを規制するために基板に設けられるロック部とを備える、ランマの車両運搬用固定装置が提供される。 In order to achieve the above-mentioned object, the upper part of the rammer having the prime mover, the lower part of the rammer having the rolling compactor plate, the stretchable anti-vibration member connecting the upper part of the rammer and the lower part of the rammer, and the handle connected to the upper part of the rammer are provided. A rammer vehicle transport fixing device for fixing the rammer in an upright position, in the vertical direction with respect to the board in an upright state for pressing the handle downward while holding the board between the board and the board. The handle was held between the board and the holding portion, the holding portion provided on the board so as to be swingable, the lever portion integrally provided on the outer surface of the holding portion for opening and closing the holding portion with respect to the board, and the holding portion. Provided is a rammer vehicle transport fixing device comprising a lock portion provided on a substrate to regulate the movement of the lever portion in a state.

この発明では、ランマを車両の荷台に載せて運搬するとき、ランマの車両運搬用固定装置の基板が荷台前方のフレームに取り付けられる。このとき、基板は立てた状態で設けられる。基板の上下方向の位置は、基板と保持部との間でランマのハンドルを保持できる高さに設定される。つぎに、ランマのハンドルが基板および／または開いた状態の保持部に対向するように、ランマが立てられた状態でランマの車両運搬用固定装置の手前まで運ばれる。その状態で、レバー部を操作して、保持部を基板に対して閉じるように下方に揺動させると、ランマのハンドルが基板と保持部との間で保持されるとともに押し下げられる。そして、ロック部によってレバー部の動きが規制され、その状態が維持される。このようにして、ランマは下方に押圧された状態でランマの車両運搬用固定装置によって保持される。このとき、ランマのハンドルが基板と保持部との間で保持されるだけではなく、保持部によってランマ自体が下方に押圧されるので、ランマ自体の重量とも相俟って、ランマ上部とランマ下部とを連結する防振部材が圧縮され弾発力を有した状態で、ランマ下部が荷台の床面に強く押し付けられる。したがって、防振部材による緩衝機能が十分に働くとともに、ランマを上下から強く支持できるので、ランマの運搬中に荷台が揺れても、運搬中の振動を吸収できるとともに、ランマの荷台への固定状態を安定させることができ、ランマを倒すことなく円滑に運搬できる。 In the present invention, when the rammer is mounted on the loading platform of the vehicle and transported, the substrate of the vehicle transport fixing device of the rammer is attached to the frame in front of the loading platform. At this time, the substrate is provided in an upright position. The vertical position of the board is set to a height at which the handle of the rammer can be held between the board and the holding portion. Next, the rammer is carried in an upright position in front of the rammer's vehicle transport fixing device so that the handle of the rammer faces the substrate and / or the holding portion in the open state. In that state, when the lever portion is operated to swing the holding portion downward so as to close the holding portion, the handle of the rammer is held and pushed down between the substrate and the holding portion. Then, the movement of the lever portion is restricted by the lock portion, and the state is maintained. In this way, the rammer is held by the vehicle transport fixing device of the rammer in a state of being pressed downward. At this time, not only the handle of the rammer is held between the board and the holding portion, but also the rammer itself is pressed downward by the holding portion. The lower part of the rammer is strongly pressed against the floor surface of the loading platform in a state where the anti-vibration member connecting the two is compressed and has elastic force. Therefore, the cushioning function of the anti-vibration member works sufficiently, and the rammer can be strongly supported from above and below. Therefore, even if the loading platform shakes during transportation of the rammer, the vibration during transportation can be absorbed and the rammer is fixed to the loading platform. Can be stabilized and can be transported smoothly without defeating the rammer.

好ましくは、保持部は、断面Ｖ字状に折り曲げられた板状部材からなる。この場合、保持部によって、ランマのハンドルを横方向の広い範囲でより安定して保持できる。また、ランマの車両運搬用固定装置の基板に対してランマのハンドルを位置決めするとき、ハンドルに多少の位置ずれがあっても、保持部を下方へ揺動させて閉じるときに、ハンドルの位置ずれを修正できる。したがって、ランマの車両運搬用固定装置によるランマの固定作業が容易になり、固定作業時間を短くできる。 Preferably, the holding portion is made of a plate-shaped member bent in a V-shaped cross section. In this case, the holding portion allows the handle of the rammer to be held more stably in a wide range in the lateral direction. In addition, when the handle of the rammer is positioned with respect to the substrate of the fixing device for transporting the vehicle of the rammer, even if the handle is slightly misaligned, the position of the handle is misaligned when the holding portion is swung downward to close. Can be fixed. Therefore, the rammer fixing work by the vehicle transport fixing device of the rammer becomes easy, and the fixing work time can be shortened.

また好ましくは、基板が取り付けられる枠状部材をさらに含む。この場合、ランマの車両運搬用固定装置の基板を車両の荷台前方のフレームに取り付けるとき、枠状部材をフレームに固定することによって、基板を間接的にフレームに取り付けることができる。すなわち、枠状部材を介することで、基板を荷台前方に容易に配置することができる。 Further preferably, a frame-shaped member to which the substrate is attached is further included. In this case, when the substrate of the vehicle transport fixing device of the rammer is attached to the frame in front of the loading platform of the vehicle, the substrate can be indirectly attached to the frame by fixing the frame-shaped member to the frame. That is, the substrate can be easily arranged in front of the loading platform via the frame-shaped member.

さらに好ましくは、ロック部は、バネカンを含む。この場合、バネカンによって、レバー部の動きを容易に規制できるとともに、運搬中の荷台の振動を吸収できる。 More preferably, the lock portion includes a spring can. In this case, the spring can easily regulates the movement of the lever portion and can absorb the vibration of the loading platform during transportation.

好ましくは、基板および保持部のそれぞれの内面に設けられる弾性部材をさらに含む。この場合、基板に設けられた弾性部材と保持部に設けられた弾性部材とによって、ハンドルを強固に保持できる。また、これらの弾性部材においても運搬中の荷台の振動を吸収できる。 Preferably, an elastic member provided on the inner surface of each of the substrate and the holding portion is further included. In this case, the handle can be firmly held by the elastic member provided on the substrate and the elastic member provided on the holding portion. Further, these elastic members can also absorb the vibration of the loading platform during transportation.

なお、ランマや基板を「立てた状態」とは、垂直に立設する場合に限定されず、傾いていてもよい。 The "standing state" of the rammer or the substrate is not limited to the case where the rammer or the substrate is erected vertically, and may be tilted.

この発明によれば、ランマを倒すことなく円滑に運搬できる。 According to the present invention, the rammer can be smoothly transported without being knocked down.

Then, the lever portion 32 and the holding portion 26 are fixed.

図９および図１０を参照して、このようなランマの車両運搬用固定装置１０は、トラック（軽トラックを含む）などの車両１によってランマ１００を立てた状態で運搬するときに好適に用いられる。ランマ１００は、原動機としてのエンジン１０２を有するランマ上部１０４と、転圧板１０６を有するランマ下部１０８と、ランマ上部１０４およびランマ下部１０８を連結する蛇腹状の伸縮可能な防振部材１１０と、ランマ上部１０４に接続されるハンドル１１２とを備える。 With reference to FIGS. 9 and 10, such a vehicle transport fixing device 10 for a rammer is suitably used when the rammer 100 is transported in an upright state by a vehicle 1 such as a truck (including a light truck). .. The rammer 100 includes a rammer upper part 104 having an engine 102 as a prime mover, a rammer lower part 108 having a rolling compactor plate 106, a bellows-shaped expandable and contractible anti-vibration member 110 connecting the rammer upper part 104 and the rammer lower part 108, and a rammer upper part. It includes a handle 112 connected to 104.

ランマの車両運搬用固定装置１０によれば、ランマ１００を車両１の荷台２に載せて運搬するとき、ランマの車両運搬用固定装置１０の基板２４が荷台２の前方のフレーム３に取り付けられる。この実施形態では、枠状部材１２の２つの貫通孔１４ｃおよび２つの貫通孔１４ｄに対応する４つの孔５１がフレーム３に設けられ、貫通孔１４ｃ，１４ｄと対応する孔５１とが合うようにフレーム３に対して枠状部材１２が位置決めされて、ボルト５２を用いてランマの車両運搬用固定装置１０の枠状部材１２がフレーム３に取り付けられる。このようにして、基板２４は、枠状部材１２を介してフレーム３に取り付けられ、立てた状態で設けられる。基板２４の上下方向の位置は、基板２４と保持部２６との間でランマ１００のハンドル１１２の横方向に延びる前部１１２ａを保持できる高さに設定される。つぎに、ハンドル１１２の前部１１２ａが基板２４および／または開いた状態の保持部２６に対向するように、ランマ１００が立てられた状態でランマの車両運搬用固定装置１０の手前まで運ばれる。その状態で、レバー部３２を操作して、保持部２６を基板２４に対して閉じるように下方に揺動させると、ハンドル１１２の前部１１２ａが基板２４と保持部２６との間で保持されるとともに押し下げられる。そして、ロック部としての座付きバネカン３６によってレバー部３２の動きが規制され、その状態が維持される。このようにして、ランマ１００は下方に押圧された状態でランマの車両運搬用固定装置１０によって保持される。このとき、ランマ１００のハンドル１１２の前部１１２ａが基板２４と保持部２６との間で保持されるだけではなく、保持部２６によってランマ１００自体が下方に押圧されるので、ランマ１００自体の重量とも相俟って、ランマ上部１０４とランマ下部１０８とを連結する防振部材１１０が圧縮され弾発力を有した状態で、ランマ下部１０８が荷台２の床面２ａに強く押し付けられる。したがって、防振部材１１０による緩衝機能が十分に働くとともに、ランマ１００を上下から強く支持できるので、ランマ１００の運搬中に荷台２が揺れても、運搬中の振動を吸収できるとともに、ランマ１００の荷台２への固定状態を安定させることができ、ランマ１００を倒すことなく円滑に運搬できる。また、ランマ１００の防振部材１１０は伸縮可能であるので、ランマの車両運搬用固定装置１０に対するハンドル１１２の位置が上下方向に多少ずれていても、そのずれを吸収してランマの車両運搬用固定装置１０によってランマ１００を円滑に保持できる。 According to the vehicle transport fixing device 10 of the rammer, when the rammer 100 is mounted on the loading platform 2 of the vehicle 1 and transported, the substrate 24 of the vehicle transport fixing device 10 of the rammer is attached to the frame 3 in front of the loading platform 2. In this embodiment, the frame 3 is provided with four holes 51 corresponding to the two through holes 14c and the two through holes 14d of the frame-shaped member 12, so that the through holes 14c and 14d and the corresponding holes 51 are aligned with each other. The frame-shaped member 12 is positioned with respect to the frame 3, and the frame-shaped member 12 of the vehicle transport fixing device 10 of the rammer is attached to the frame 3 by using the bolt 52. In this way, the substrate 24 is attached to the frame 3 via the frame-shaped member 12 and is provided in an upright state. The vertical position of the substrate 24 is set to a height at which the laterally extending front portion 112a of the handle 112 of the rammer 100 can be held between the substrate 24 and the holding portion 26. Next, the rammer 100 is carried upright to the front of the vehicle transport fixing device 10 of the rammer so that the front portion 112a of the handle 112 faces the substrate 24 and / or the holding portion 26 in the open state. In that state, when the lever portion 32 is operated to swing the holding portion 26 downward so as to close the holding portion 26 with respect to the substrate 24, the front portion 112a of the handle 112 is held between the substrate 24 and the holding portion 26. It is pushed down with the lever. Then, the movement of the lever portion 32 is restricted by the seated spring can 36 as the lock portion, and the state is maintained. In this way, the rammer 100 is held by the vehicle transport fixing device 10 of the rammer in a state of being pressed downward. At this time, not only the front portion 112a of the handle 112 of the rammer 100 is held between the substrate 24 and the holding portion 26, but also the rammer 100 itself is pressed downward by the holding portion 26, so that the weight of the rammer 100 itself is heavy. Together with this, the rammer lower portion 108 is strongly pressed against the floor surface 2a of the loading platform 2 in a state where the vibration-proof member 110 connecting the rammer upper portion 104 and the rammer lower portion 108 is compressed and has elastic force. Therefore, since the cushioning function of the anti-vibration member 110 works sufficiently and the rammer 100 can be strongly supported from above and below, even if the loading platform 2 shakes during transportation of the rammer 100, the vibration during transportation can be absorbed and the rammer 100 can be supported. The fixed state to the loading platform 2 can be stabilized, and the rammer 100 can be smoothly transported without being knocked down. Further, since the anti-vibration member 110 of the rammer 100 can be expanded and contracted, even if the position of the handle 112 with respect to the vehicle transportation fixing device 10 of the rammer is slightly displaced in the vertical direction, the displacement is absorbed and the rammer is used for vehicle transportation. The fixing device 10 can smoothly hold the rammer 100.

保持部２６は、断面Ｖ字状に折り曲げられた切妻状の板状部材からなるので、保持部２６によって、ランマ１００のハンドル１１２の前部１１２ａを横方向の広い範囲でより安定して保持できる。また、ランマの車両運搬用固定装置１０の基板２４に対してハンドル１１２の前部１１２ａを位置決めするとき、ハンドル１１２の前部１１２ａに多少の位置ずれがあっても、保持部２６を下方へ揺動させて閉じるときに、ハンドル１１２の前部１１２ａの位置ずれを修正できる。したがって、ランマの車両運搬用固定装置１０によるランマ１００の固定作業が容易になり、作業時間を短くきる。 Since the holding portion 26 is composed of a gable-shaped plate-shaped member bent into a V-shaped cross section, the holding portion 26 can more stably hold the front portion 112a of the handle 112 of the rammer 100 in a wide range in the lateral direction. .. Further, when the front portion 112a of the handle 112 is positioned with respect to the substrate 24 of the vehicle transport fixing device 10 of the rammer, the holding portion 26 is shaken downward even if the front portion 112a of the handle 112 is slightly displaced. The misalignment of the front portion 112a of the handle 112 can be corrected when it is moved and closed. Therefore, the fixing work of the rammer 100 by the vehicle transport fixing device 10 of the rammer becomes easy, and the working time can be shortened.

ランマの車両運搬用固定装置１０の基板２４を車両１の荷台２の前方のフレーム３に取り付けるとき、枠状部材１２をフレーム３に固定することによって、基板２４を間接的にフレーム３に取り付けることができる。すなわち、枠状部材１２を介することで、基板２４を荷台２の前方に容易に配置することができる。 When the substrate 24 of the vehicle transport fixing device 10 of the rammer is attached to the frame 3 in front of the loading platform 2 of the vehicle 1, the substrate 24 is indirectly attached to the frame 3 by fixing the frame-shaped member 12 to the frame 3. Can be done. That is, the substrate 24 can be easily arranged in front of the loading platform 2 via the frame-shaped member 12.

バネカン４０によって、レバー部３２の動きを容易に規制できるとともに、運搬中の荷台２の振動を吸収できる。 The spring can 40 can easily regulate the movement of the lever portion 32 and can absorb the vibration of the loading platform 2 during transportation.

基板２４に設けられた弾性部材３０ａと保持部２６に設けられた弾性部材３０ｂ，３０ｃとによって、ハンドル１１２を強固に保持できる。また、これらの弾性部材３０ａ，３０ｂ，３０ｃにおいても運搬中の荷台２の振動を吸収できる。 The handle 112 can be firmly held by the elastic members 30a provided on the substrate 24 and the elastic members 30b and 30c provided on the holding portion 26. Further, these elastic members 30a, 30b, and 30c can also absorb the vibration of the loading platform 2 during transportation.

なお、上述の実施形態では、ゴムチューブ３４は、枠状部１２の板状部１４ａと棒状部１６ａとの接続箇所に掛けられるとともに、ハンドル部３２ｃに掛けられたが、これに限定されない。たとえば、図２に示すように、棒状部１６ａおよびハンドル部３２ｃのそれぞれにＵ字状のフック５４を設け、これらのフック５４にゴムチューブ３４を取り付けてもよい。また、ゴムチューブ３４と同様の機能を有する部材として、軸部３２ａに巻き付けられたばね部材が用いられてもよい。この場合、ゴムチューブ３４は必ずしも必要ではない。 In the above-described embodiment, the rubber tube 34 is hung on the connection portion between the plate-shaped portion 14a and the rod-shaped portion 16a of the frame-shaped portion 12 and is hung on the handle portion 32c, but the present invention is not limited thereto. For example, as shown in FIG. 2, a U-shaped hook 54 may be provided on each of the rod-shaped portion 16a and the handle portion 32c, and a rubber tube 34 may be attached to these hooks 54. Further, as a member having the same function as the rubber tube 34, a spring member wound around the shaft portion 32a may be used. In this case, the rubber tube 34 is not always necessary.

図１に示すように、さらに、保持部２６の外面にＵ字状のフック５５ａを設け、基板２４にワイヤ５５ｂを介してフック金具５５ｃを取り付けてもよい。フック金具５５ｃは、ばねによるロック機構を有する。この場合、図６に示すように、保持部２６を基板２４に対して閉じた状態で、フック金具５５ｃをフック５５ａに掛けることによって、ランマ１００のハンドル１１２を基板２４と保持部２６との間でより確実に保持できる。 As shown in FIG. 1, a U-shaped hook 55a may be further provided on the outer surface of the holding portion 26, and the hook metal fitting 55c may be attached to the substrate 24 via the wire 55b. The hook metal fitting 55c has a locking mechanism by a spring. In this case, as shown in FIG. 6, the handle 112 of the rammer 100 is placed between the substrate 24 and the holding portion 26 by hooking the hook metal fitting 55c to the hook 55a in a state where the holding portion 26 is closed with respect to the substrate 24. Can be held more reliably with.
