Reference numeral 5 denotes a detachable hook member that is fixed to one end of the elastic member 2a by a bolt 6 that is screwed into a female thread for bolting the core metal 3. Similarly, it has a shape that engages with the end of the shoe plate 1 in a disengageable manner, and has a fastening seat portion 5a at one end thereof.
【0007】 上記弾性部材2aは天然ゴム、合成ゴムさらにはプラスチック等の硬質の弾性 ゴム材にて構成されており、これに内装される芯金3及びこれの端部に溶着され 固定鉤部材4の一部が、この弾性部材2aの成形時にインサート成形される。 弾性部材2aの幅及び長さはこれを用いる履板1の種類によって変えられる。 そしてその幅によって芯金3を1本あるいは幅方向に離隔して2本配設する。The elastic member 2a is made of a hard elastic rubber material such as natural rubber, synthetic rubber, or plastic, and the core metal 3 installed therein and the fixed hook member 4 welded to the end portion thereof. Is partially insert-molded when the elastic member 2a is molded. The width and length of the elastic member 2a can be changed depending on the type of the track plate 1 using the elastic member 2a. Depending on the width, one core metal 3 or two metal cores 3 are arranged at a distance in the width direction.
【0008】 弾性部材は2aの踏面には滑り止め溝7が形成されている。この滑り止め溝7 は長さ方向に山形に形成されているが、図2に示すように一方向に、あるいは図 4に示すように左右で対向するように設けられている。 また弾性部材2aの下面には履板1の踏面のラグに係合する溝8がその全長に わたって設けてあり、また長さ方向に中間部に切欠き部9が形成してある。 さらに弾性部材2の下面で履板1に当接する部分に複数個の凹部10が設けら れている。 なお上記芯金3の露出側の端面は弾性部材2aの端部より凹ました部分に露出 しており、着脱鉤部材5の締着座部5aは弾性部材2aの端部より内側にてボル ト結合されるようになっていて、この部分が走行路面に接触しないようになって いる。An anti-slip groove 7 is formed on the tread surface of the elastic member 2a. The anti-slip grooves 7 are formed in a mountain shape in the length direction, but are provided so as to face each other in one direction as shown in FIG. 2 or left and right as shown in FIG. Further, on the lower surface of the elastic member 2a, a groove 8 that engages with a lug on the tread surface of the shoe plate 1 is provided over the entire length thereof, and a cutout portion 9 is formed at an intermediate portion in the longitudinal direction. Further, a plurality of recesses 10 are provided in a portion of the lower surface of the elastic member 2 that abuts on the shoe plate 1.

It is designed to prevent contact with the road surface.
【0009】 上記構成において、履帯用パットを履板1へ取付けるには、一方の着脱鉤部材 5を取外した状態で、弾性部材2aの下面を履板1の踏面に接合し、かつ固定鉤 部材6を履板1の一側端部に係合する。ついで、着脱鉤部材5を履板1の他側端 部に係合すると共に、これの締着座部5aをボルト6にて芯金3に固着する。 またこれの取外しは、上記手順を逆に行うことにより簡単に行われる。 上記取付け状態の履帯用パッドにおいて、これの上面が走行時に接地するが、 この踏面に長手方向に山形にした滑り止め溝7が設けてあることにより横方向へ のスリップすることなく走行される。 またこのとき、弾性部材2aの下面で履板1に当接する部分に複数個の凹部1 0があることにより、この下面部における弾性が大きくなる。 上記構成における弾性部材2aの芯金3にパイプ材が用いられていることによ り、これが2本用いられている場合でも、この芯金3にて弾性部材2aが厚み方 向に2分されることがなく、従って弾性部材2aの厚み方向の変形は、これの全 厚さにわたって有効に行われる。In the above structure, in order to attach the crawler belt pad to the shoe plate 1, the lower surface of the elastic member 2a is joined to the tread surface of the shoe plate 1 with one detachable hook member 5 removed, and the fixed hook member is also attached. 6 is engaged with one end of the track plate 1. Next, the detachable hook member 5 is engaged with the other end of the shoe plate 1, and the fastening seat portion 5 a of the detachable hook member 5 is fixed to the core metal 3 with the bolt 6. Further, the removal of this can be easily performed by reversing the above procedure. In the above-mentioned mounted crawler belt pad, the upper surface thereof comes into contact with the ground when traveling, but the tread surface is provided with the mountain-shaped anti-slip groove 7 to allow traveling without lateral slippage. Further, at this time, since the lower surface of the elastic member 2a has a plurality of recesses 10 in the portion contacting the shoe plate 1, the elasticity of the lower surface portion is increased. Since the pipe member is used for the core metal 3 of the elastic member 2a in the above configuration, even when two pipe members are used, the core metal 3 divides the elastic member 2a into two in the thickness direction. Therefore, the elastic member 2a is effectively deformed in the thickness direction over its entire thickness.
【0010】 上記実施例では、ボルト6にて着脱鉤部材5を芯金3に固着する例を示したが 、これは図5に示すようにナット11にて固着してもよい。この場合芯金3aの 他端部にナット用のおねじを設け、この部分に着脱鉤部材5の締着座部5aを嵌 合し、ナット11にて締着するようにしてもよい。In the above embodiment, an example in which the detachable hook member 5 is fixed to the core metal 3 with the bolt 6 has been shown, but this may be fixed with the nut 11 as shown in FIG. In this case, a male thread for a nut may be provided at the other end of the core metal 3a, and the fastening seat portion 5a of the detachable hook member 5 may be fitted to this portion and the nut 11 may be used for fastening.
【0011】 また上記実施例では締着部材であるボルト6、ナット11が弾性部材2aの端 面より内例に引っこんでいる構成となっているが、この部分に土砂がつまること がある。 このため、図6に示すように、弾性部材2aの端部に上記ボルト6、ナット1 1をカバーするカバー部材12を設けてもよい。 この場合のカバー部材12は、これの根元部が薄くなっていて容易に撓むこと ができるようになっており、ボルト6、ナット11を螺合するときにはこれを上 方撓へみ曲げておき、螺合後これをボルト6、ナット11に嵌合する。 なおこの構成によれば、上記したように締着部材の部分に土砂がつまるのを防 止できるほかに、締着部材がカバー部材12にてかくれることにより、これをゆ るめてはずすという盗難をも防ぐことができる。 なお上記カバー部材12は弾性部材2aに連結した例を示したが、これを単独 、すなわち、弾性部材2aとは別部材の部品としてもよい。Further, in the above embodiment, the bolt 6 and the nut 11 which are fastening members are configured to be retracted inward from the end surface of the elastic member 2a, but earth and sand may be caught in this portion. Therefore, as shown in FIG. 6, a cover member 12 for covering the bolt 6 and the nut 11 may be provided at the end of the elastic member 2a. In this case, the cover member 12 has a thin base portion so that it can be easily bent. When the bolt 6 and the nut 11 are screwed together, the cover member 12 is bent upward and bent. After screwing, the bolt 6 and the nut 11 are fitted to each other. According to this configuration, as described above, it is possible to prevent the clogging member from being clogged with soil and sand, and the fastening member is covered by the cover member 12 to loosen it. Theft can also be prevented. Although the cover member 12 is connected to the elastic member 2a by way of example, it may be a single member, that is, a component separate from the elastic member 2a.
【0012】 履帯用パッド2を履板1に係合する鉤部材のうち、着脱鉤部材5には、その形 状上、図1その他に示すように履板1のラグに係合する切欠き13が設けられて いるが、この切欠き13は固定鉤部材側にも設けることにより履板用パッド2は より強固に履板1に係合することができる。 図7,8はその一例を示すもので、固定鉤部材4の上部を着脱鉤部材5の締着 座部5aと略同じ形状にし、この部分に芯金3,3aの端部を溶着する。そして この部分に履板1のラグが係合する切欠き13を設ける。Among the hook members that engage the crawler belt pad 2 with the shoe plate 1, the detachable hook member 5 has a notch for engaging the lug of the shoe plate 1 as shown in FIG. Although the notch 13 is provided, the notch 13 is also provided on the fixed hook member side so that the track pad 2 can be more firmly engaged with the track 1. 7 and 8 show one example thereof, the upper portion of the fixed hook member 4 is formed into substantially the same shape as the fastening seat portion 5a of the detachable hook member 5, and the end portions of the cored bars 3 and 3a are welded to this portion. Then, a notch 13 with which the lug of the shoe plate 1 engages is provided in this portion.
【0013】 さらに履帯用パッド2の弾性部材2aの踏面の周囲には斜面が形成されている が、これの幅方向両側の斜面2b、2bは図3に示すように20〜30°傾斜に なっていて、角度範囲にすることにより、走行中に隣接する履帯用パッド2の相 互間に障害物が噛み込むのを防止できる。Further, slopes are formed around the tread surface of the elastic member 2a of the crawler belt pad 2, and the slopes 2b and 2b on both sides in the width direction thereof are inclined by 20 to 30 ° as shown in FIG. However, by setting the angle range, it is possible to prevent an obstacle from being caught between the adjacent crawler belt pads 2 during traveling.
【0014】 図9,10,11は履帯用パッド2の弾性部材2aの踏面形状の他側を示すも ので、弾性部材2aの踏面2bを走行方向に対して山形にしてもよい。Since FIGS. 9, 10 and 11 show the other side of the tread surface of the elastic member 2a of the crawler belt pad 2, the tread surface 2b of the elastic member 2a may be mountain-shaped in the traveling direction.
【0015】[0015]
本考案によれば、履帯用パッド2の弾性部材2aを構成する弾性ゴム材の実質 的な厚さが履帯用パッド2の全体の厚さになり、走行時における緩衝効果及び強 度の向上を図ることができる。また履帯用パッド2の弾性部材2aの上面に長手 方向に山形にした滑り止め溝7が設けられていることにより、走行時の横方向へ のスリップがなくなる。 またその他の効果として、履帯用パッド2を履板1に取付けるためのボルト6 あるいはナット11等の締着部材をカバー部材12にてカバーしたことにより、 この締着部材の周囲に土砂がつまることかくなると共に、これの姿が直接見えな いことにより、これにスパナをかけてゆるめようとする意欲を殺いで、盗難防止 としての効果を有する。 さらに弾性部材2aの踏面の幅方向両側に角度が20〜30°の斜面を設けた ことにより、走行中に隣接する履帯用パッド2の相互間に障害物が噛み込むのを 防止できる。 そしてさらに、弾性部材2aの履板1の踏面に接触する部分は、この部分に設 けた複数個の凹部10により、この部分は履板1の踏面になじみよく接合する。 According to the present invention, the substantial thickness of the elastic rubber material forming the elastic member 2a of the crawler pad 2 becomes the entire thickness of the crawler pad 2, which improves the cushioning effect and strength during running. Can be planned. Further, since the mountain-shaped anti-slip groove 7 is provided in the longitudinal direction on the upper surface of the elastic member 2a of the crawler belt pad 2, there is no lateral slip during traveling. Further, as another effect, the cover member 12 covers the fastening member such as the bolt 6 or the nut 11 for attaching the crawler belt pad 2 to the track plate 1, so that earth and sand are clogged around the fastening member. As it becomes harder and invisible, it has the effect of preventing theft by killing the motivation to loosen it with a spanner. Further, by providing slopes with an angle of 20 to 30 on both sides in the width direction of the tread surface of the elastic member 2a, it is possible to prevent an obstacle from being caught between the adjacent crawler belt pads 2 during running. Further, the portion of the elastic member 2a that comes into contact with the tread surface of the shoe plate 1 is well joined to the tread surface of the shoe plate 1 due to the plurality of recesses 10 provided in this portion.
