The structure was such that the hook member (2) was digged in.

[0003]

[Problems to be solved by the invention]

 However, if the slipboard on the rough road escapes on a snowy road or a frozen road, and is used under a wheel when it is slipped on a snowy road or a frozen road, it can be used on a hard snowy road or a frozen road. In many cases, the tool member (2) bites the road surface without cutting into the road surface, and the floor board is caught in the wheel, so that it is often impossible to escape from the place.

[0004] The present invention provides a slab for escaping a rough road of an automobile, which can reliably escape even when a slip occurs on a snowy road, a frozen road, or the like, or when a wheel falls into a gutter or the like.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, that is, when a slip occurs on a snowy road or a frozen road, the surface of a soft band such as a rubber plate is made of metal. By arranging a large number of wheel hanging members such as channel members at a predetermined interval so as to protrude, wheels are prevented from slipping, and a block-shaped contact member is provided on the back surface of the band so as to face the hanging member upward and downward. With this arrangement, the contact member is brought into close contact with the surface of a hard snowy road, a frozen road, or the like, so that the belt is prevented from being caught.

[0006] In addition, when a wheel falls into a gutter or gets stuck in a frozen mud such as a rut, a wheel hook member such as a metal groove member is provided on the surface of a soft band such as a rubber plate. Are protruded and arranged at predetermined intervals, and a block-shaped road surface contact member is provided on the back surface of the band so as to be vertically opposed to the hanging member, and in particular, a block-shaped auxiliary plate longer than the width of the band is provided. When the auxiliary plate is used by being inserted into the back surface of the band, the auxiliary plate may bite into the gutter or the rut, or the contact resistance may be increased.

[0007]

[Embodiment of the invention]

 FIG. 1 is a diagram showing an embodiment of the present invention, and description will be made based on this. (1) is a soft band such as a rubber plate, a cloth band, a soft synthetic resin plate or the like, and fixing holes (11) are provided at both ends of the band (1) for driving and fixing a pile, a nail, or the like. Are drilled. The belt (1) has a sufficient hardness that can be rolled up when stored, and a rubber belt is used. In particular, for a large vehicle, a rubber belt with cloth is preferably used. The fixing hole (11) may be formed only at one end of the band (1). Reference numeral (2) denotes a hook member for a wheel such as a metal channel formed so as to protrude from the surface of the band (1) at predetermined intervals, and the cross section of the hook member (2) has a U-shape. It is formed of steel, stainless steel, aluminum alloy or the like. The cross section of the hanging member (2) is not limited to a U-shape. (3) is a block-shaped road surface sealing member provided on the back surface of the band (1) and vertically opposed to the hanging member (2). It is formed into a shape and has elasticity. The material is a natural rubber used for tires, such as natural rubber, SBR, IR, and BR. HsA40-70 is used as the hardness, and HsA65 is preferable. The material of the contact member (3) may be not only rubber but also synthetic resin having elasticity, and the cross section is not limited to the inverted trapezoidal shape. (4) is an embedding metal fitting buried in the contact member (3). The embedding metal fitting (4) has a metal plate (41) buried inside the contact member (3) and the metal plate (41). There is a screw rod (42) that stands vertically and has a tip protruding from the contact member (3) (see FIGS. 3 and 4). (5) is a fastening member comprising a hexagon nut, a washer, and the like, which serves to fix the hook member (2) to the contact member (3) across the strip (1) by attaching to the screw rod (42). is there.

FIG. 2 is a diagram showing another embodiment of the present invention, which will be described based on this. (1) is a soft band, (2) is a hook member for a wheel, (3) is a contact member for a road surface, (4) is an embedding bracket, and (5) is a fastening member. The same components as those in the above embodiment may be used. (6) is a block-shaped auxiliary plate used on the back surface of the band (1) and inserted between the contact members (3). The material of the auxiliary plate (6) is a hard rubber plate, a hard synthetic resin. Use a board, a wooden board, a metal plate, or the like. The length of the auxiliary plate (6) is 1.5 to 4 times as long as the width of the band (1), but a length of 2 to 3 times is preferable. If the length is less than 1.5 times and is close to the length of the band (1), there is a risk that it will not be able to fulfill the role of sinking into the mud and fixing it. May be worse. The thickness of the auxiliary plate (6) is preferably equal to or less than the thickness of the contact member (3).

Next, the operation of the present invention will be described. First, if the vehicle wheels (7) cannot slip out on hard snowy roads or frozen roads, first insert the product under the drive-side wheels (7). At this time, a pile or the like is preferably driven into a fixing hole (11) drilled at one end of the band (1). Next, when the automobile is slowly moved, the wheel (7) is cut into the hanging member (2) provided on the surface of the band (1), and the contact member (3) provided on the back surface of the band (1). ) Adheres to the frozen hard road surface and cuts into the unevenness of the road surface (see Fig. 5). As a result, the friction between the road surface and the contact member (3) increases, and the belt (1) can be fixed without being caught, so that the wheel (7) reliably catches the hook member (2). Therefore, if the wheel (7) rotates slowly, the car can escape on its own. After escaping, pull out the stake, remove it from the fixing hole (11), roll the band (1) and put it in the trunk. At this time, even if the pile is not driven, the sticking member (3) will surely catch the road surface. Therefore, when using the product of the present invention, the pile is normally used without driving.

[0010] Next, when the wheels (7) of the automobile cannot escape due to slippage due to muddy mud or sand, or when the wheels (7) fall into the gutters, the driving side first. Insert the product under the wheel (7). It is also preferable to drive a pile or the like into the fixing hole (11) drilled at one end of the band (1). Next, when the automobile is slowly moved, the wheel (7) is cut into the hook member (2) provided on the surface of the band (1) as described above, and is provided on the back surface of the band (1). Since the contact member (3) is in contact with the slippery road surface or the side groove and also cuts into the unevenness or the side groove of the road surface, the friction is increased and the band (1) is fixed without being caught. At this time, even if the pile is not driven, the belt (1) itself does not move, and the wheel (7) securely catches the hook member (2). If the wheel (7) rotates slowly in this state, the wheel (7) bites into the hanging member (2), and the car can escape from muddy roads or side grooves without the help of another person. is there. After escape, pull out the pile, remove it from the fixing hole (11), and roll the band (1) into the trunk.

[0011] Further, when the wheel (7) of the car falls into a frozen rut or a muddy pit, and a slip occurs at that place, even if an attempt is made to escape with the conventional product, the wheel (7) is wound under the wheel (7). In many cases, she could not escape because she was engulfed. In this case, if the auxiliary plate (6) shown in FIG. 2 of another embodiment of the present invention is used together, it is possible to easily escape with little involvement. The operation of the auxiliary plate (6) will be described in detail with reference to FIG. First, insert the product of the present invention under the wheel (7) and insert the auxiliary plate (6) on the back of the band (1) and between the first and second sealing members (3). The auxiliary plate (6) is arranged so as to evenly protrude from both sides of the band (1), and the band (1) is inserted under the wheel (7) [see FIG. 6 (a)]. Next, when the wheel (7) is slowly rotated, the wheel (7) is bitten into the hook member (2) provided on the surface of the band (1), and the band (1) is also rolled in [FIG. )reference]. Then, together with the contact member (3), the auxiliary plate (6) bites into a rut, a depression, or the like, and the contact member (3) is supported by the auxiliary plate (6), and the band (1) is attached to the auxiliary plate (6). 6). Furthermore, when the wheel (7) is rotated slowly, the wheel (7) rotates and, while the band (1) itself is firmly fixed, securely catches the hanging member (2) while riding. See FIG. 6 (c)]. As a result, the car can escape on its own. At this time, the auxiliary plate (6) is longer than the width of the wheel (7) when viewed from the front-rear direction. This is the state in which it is in the state shown in FIG. 6 (d). After escape, the band (1) and the auxiliary plate (6) should be collected, and the band (1) should be rolled and put in the trunk. When the road surface is hard, the auxiliary plate (6) does not penetrate, but the contact area increases with the road surface and the contact resistance increases, so that a state in which the road surface is prevented from being entangled can be ensured.

[0012]

[Effect of the invention]

 With this configuration, the present invention has the following effects.

As shown in claim 1, on the surface of the band (1), a large number of hook members (2) such as metal channels are arranged so as to protrude at predetermined intervals, and the band (1). By providing a block-shaped contact member (3) having elasticity on the back surface of the vehicle so as to be vertically opposed to the hanging member (2), the conventional product is of a type that bites into the road surface, so that hard snow is hardened. Even on a rough road where the vehicle slips on a road or icy road without biting into the road surface and causing galling, the product of the present invention is deformed because the contact member (3) is crushed by the weight of the wheel (7). Therefore, the contact member (3) is further adhered to the road surface, and the wheel (7) gets over the hook member (2) while digging into the hanging member (2), so that the vehicle can surely escape by itself.

According to a second aspect of the present invention, a plurality of hook members (2), such as metal channels, are arranged on the surface of the band (1) so as to protrude at predetermined intervals, and the band (1) is formed. An elastic block-shaped contact member (3) is provided on the back surface of the belt member so as to be vertically opposed to the hook member (2), and is 1.5 to 4 times as long as the width of the band (1). By providing the block-shaped auxiliary plate (6) having the following effects, the same effect as in claim 1 can be obtained, and particularly when the auxiliary plate falls into a icy rut or a muddy pit which is difficult to escape. Even so, the vehicle can escape from that location.

By using a soft material such as a rubber plate, a cloth band, a soft synthetic resin plate or the like as the belt body (1), the belt-shaped product of the present invention is easily rolled, stored or held. It is convenient for carrying around.

The cross section of the hook member (2) is formed in a U-shape, and the cross section of the contact member (3) is formed in an inverted trapezoidal shape. An embedding metal fitting (4) is provided inside the metal plate (41) so that the screw rod (42) is erected and fixed on the metal plate (41) and the tip of the screw rod (42) protrudes. By fixing the sealing member (3) and the fastening member (5) such as a hexagonal nut with the band (1) sandwiching the band (1), the hook member (2) and the adhesion member (3) may be damaged. When worn, it is possible to maintain good condition for a long time by replacing only the damaged or worn parts without purchasing new ones. Further, by embedding the metal plate (41) inside the contact member (3), the strength of the contact member (3) itself and the mounting strength can be improved. Further, even if the length of the band (1) is various, the hook member (2), the close contact member (3), the embedding metal fitting (4), the fastening member (5), and the auxiliary plate (6) are common parts. Because it can be used as a part, it becomes easy to make parts management and production plans, and cost reduction is possible.

When the auxiliary plate (6) is formed of a hard rubber plate as described in claim 5, the contact area with the road surface is increased and the contact resistance due to close contact is increased, so that the band (1) is entangled. It can be prevented. When the auxiliary plate (6) is formed of a synthetic resin plate, the contact area with the road surface is increased and mass production is facilitated. When a wooden plate is used as the auxiliary plate (6), it can be easily manufactured simply by cutting a commercially available one. You can do it. When the auxiliary plate (6) is made of a metal plate, it can be made lightweight if it is formed of a thin plate whose cross section is bent in a substantially U-shape or the like.
