本滑り止め具Ａの他の使用状態について説明すると、図１の仮想線で示すように、両滑り止め体１、２間において、両者に螺設されたネジ孔１３を介してぬかり防止具２９が接合される。ぬかり防止具２９は図１２に示すように、上面を開口し内部に空室３０を形成したボックス状の脚３１でぬかるみに対応できるから、深いシャーベット状の雪路や泥土
を走行するときは、空室３０に雪や泥を噛み込んですべりを解消するとともに、剛直体で
あるからゴム履帯４の側端部のへたりが解消されてその沈み込みが防止される。
また、図１３に示したぬかり防止具２９は、密閉空間を形成したフロート状の脚３１が
、両端のフランジ３２で左右の両滑り止め体１，２の係着部８にネジ孔１３を介してボル
ト締めされるもので、主として湿田や湿地などで作業するときに使用され、ぬかるみの接
地圧を減少させるとともに、剛直体であるから前記と同様にゴム履帯４の左右側端のへた
りが解消されて沈み込みが防止される。 The other use state of the anti-skid tool A will be described. As shown by the phantom line in FIG. 1, the anti-skid tool 29 is interposed between the anti-slip bodies 1 and 2 through the screw holes 13 screwed on both. Are joined. As shown in FIG. 12, the anti-wetting device 29 can cope with the muddyness with a box-shaped leg 31 having an upper surface opened and an empty chamber 30 formed therein, so when traveling on a deep sherbet-like snow road or mud, The slippage is eliminated by biting snow and mud into the vacant chamber 30, and since it is a rigid body, the sag of the side end portion of the rubber crawler belt 4 is eliminated and its sinking is prevented.
Further, the anti-wetting tool 29 shown in FIG. 13 has a float-like leg 31 that forms a sealed space, and the flanges 32 at both ends are connected to the engaging portions 8 of the left and right anti-slip bodies 1 and 2 through the screw holes 13. It is bolted and used mainly when working in wet fields and wetlands, etc., and reduces the contact pressure of the muddy, and since it is a rigid body, the left and right side sag of the rubber crawler belt 4 is the same as described above. It is eliminated and sinking is prevented.

本滑り止め具Ａ、Ｂにおける滑り止め体の特異な構造的特徴を述べると、ゴム履帯４への装着状態での走行時の圧雪反力がクサビ部７での凹条部５に対するクサビ作用のみならず、左右の係着座１７からの各凸条部６の圧縮力に伴う変形によって凹条部５の両壁面に
押圧応力が発現し、一層クサビ作用が強くなり、キック力が増大して滑り止め効果が向上する。
また、キック時の回転力（浮き上がり力）に対しては、何れか一方の係着座１７と凸条部６の頂面及び反対側のクサビ部７の傾斜辺１６とこれに対応する凹条部５の壁面によって対抗するため、単に凸条部６に被さる滑り止め体とは大きく異なり、浮き上がりなどの
ガタが生じないから、凸条部６の角部が丸く擦り減ることがない。このほか、位置決め部材９の下端でゴム履帯４の裏面にむけて突設される挟み部１１は、該裏面との接触面が円弧面１０である上、その位置がほぼ凹条部５に対応する位置にあるから、ゴム履帯４の前後の車輪に案内される部分で凹条部５がその上端を拡開され、その裏面が内に絞られる状態となっても、挟持状態に無理がなく、スムーズに通過できる。 The unique structural features of the anti-slip bodies in the anti-skid tools A and B are described. Only the wedge action on the concave strip portion 5 at the wedge portion 7 is caused by the pressure-snow reaction force when running on the rubber crawler belt 4. In addition, the deformation caused by the compressive force of the convex portions 6 from the left and right engaging seats 17 causes a pressing stress on both wall surfaces of the concave portions 5, the wedge effect becomes stronger, the kick force increases, and slipping occurs. The stopping effect is improved.
Further, with respect to the rotational force (lifting force) at the time of kicking, any one of the engaging seats 17, the top surface of the ridge portion 6, the inclined side 16 of the wedge portion 7 on the opposite side, and the corresponding ridge portion Since it is countered by the wall surface 5, it is greatly different from an anti-slip body that simply covers the ridge 6, and there is no backlash or other looseness, so that the corners of the ridge 6 do not wear out roundly. In addition, the pinching portion 11 projecting toward the back surface of the rubber crawler belt 4 at the lower end of the positioning member 9 has an arc surface 10 in contact with the back surface, and the position thereof substantially corresponds to the concave portion 5. Since the upper end of the concave strip 5 is widened at the portion guided by the front and rear wheels of the rubber crawler belt 4 and the back surface is squeezed inward, there is no difficulty in the clamping state. Can pass smoothly.
