Description

[Technical Field]

[0001] The present invention relates to a rough road escape tool for a vehicle. [Background technology]

[0002] Conventionally, rough road escape tools for vehicles have been known that are laid on rough roads such as snowy roads or muddy roads to enable the vehicle to escape when the vehicle's wheels get stuck in a depression in the road and the vehicle is unable to escape by itself (see, for example, Patent Document 1). Examples of depressions in rough roads include large holes that appear above manholes (which are at a higher temperature than the surrounding area) when snow accumulates.

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 5-84503 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the rough road escape tool for vehicles described in Patent Document 1 does not take into consideration weight reduction at all, and is heavy, causing problems such as it being difficult to handle by hand during use. Moreover, its shape makes it difficult to hold by hand during use. Furthermore, in addition to the rough road escape tool for vehicles, a (large) shovel is required, which is bulky when kept in the vehicle.

[0005] Therefore, the object of the present invention is to provide a rough-road escape tool for vehicles that is lightweight overall (by solving such conventional problems) and has sufficient strength and rigidity to withstand the load of a vehicle (tire). Another object is to provide a rough-road escape tool for vehicles that does not require a separate shovel. Yet another object is to provide a rough-road escape tool for vehicles that is easy to use and can be easily and reliably gripped by hand and used to apply force. [Means for solving the problem]

[0006] The rough road escape device for vehicles according to the present invention is a rectangular plate in plan view, with a large number of holes arranged in a pattern over almost the entire surface of the front face, a downwardly sloping surface inclined forward in the front half of the front face, a scoop portion formed in the front half of the back face, and no anti-slip protrusions formed on the front face. Further, a middle plate portion is formed at the middle position in the thickness direction to close each of the holes.

[0007] In addition, left and right horizontally elongated window portions are provided near the rear end edge, and the rear end edge is left in place to form a first horizontal gripping rod portion, and a pair of front and rear vertically elongated window portions are provided at a midpoint between the front and rear, and a second vertically elongated window portion is formed between the pair of front and rear vertically elongated window portions. The first gripping rod and the second gripping rod are disposed below the front surface. The opening width of the left and right horizontally elongated window portions is set to 20 mm or more, and the opening width of the front and rear vertically elongated window portions is set to 20 mm or more.

[0008] The hole is formed into a hexagonal shape in a plan view, and the hole is disposed so that a pair of opposite sides of the hexagon are aligned in the front-rear direction. The hole is formed in a hexagonal shape in plan view, and the distance between a pair of opposite sides of the hexagon is set to 16 mm or less. [Effects of the Invention]

[0009] The rough road escape tool for vehicles of the present invention can reduce the overall weight, yet has sufficient strength and rigidity to withstand the weight of the vehicle. Furthermore, since a large shovel is not required, it can save space when kept in the vehicle. [Brief explanation of the drawings]

[Figure 5] FIG. 10 is an explanatory diagram showing the arrangement direction of the holes. [Figure 6] FIG. 10 is an explanatory diagram showing a comparative example. DETAILED DESCRIPTION OF THE INVENTION

[0011] The present invention will be described in detail below based on the illustrated embodiments. 1 to 5 show an embodiment of the present invention. The rough road escape tool for vehicles of the present invention is a plate-like device that is rectangular in plan view, with a large number of holes 2 arranged in a pattern over substantially the entire surface (tire contact surface) 1. The holes 2 are hexagonal in plan view. The front half of the surface 1 has an inclined surface 3 that slopes downward toward the front. In the present invention, the "front half" refers to the range from 30% to 60% of the front.

[0012] A scoop portion (scoop recess) 5 is formed in the front half of the back surface (bad road contact surface) 4. Macroscopically, the scoop portion 5 is a recess with multiple ridges 13 formed in the front-rear direction, and grooves 15 are formed between adjacent ridges 13. The ridges 13 prevent snow and mud scooped up by the scoop portion 5 from falling sideways. In addition, no (localized) anti-slip projections are formed on the front surface 1.

[0013] A middle plate portion 6 is formed at the middle position in the thickness direction to close each hole portion 2 (see FIG. 4). Preferably, the middle plate portion 6 is formed at the center position in the thickness direction (approximately halfway in the thickness direction).

[0014] Left and right horizontally elongated windows 8 are provided near the rear end edge 7, and a first horizontal grip rod 9 is formed at the rear end edge 7. A pair of front and rear vertically elongated windows 10, 10 are provided at the front-rear intermediate position, and a second vertical grip rod 11 is formed between the pair of front and rear vertically elongated windows 10, 10.

[0015] The first gripping rod 9 and the second gripping rod 11 are disposed below the front surface 1 .

[0016] The opening width W1 of the left and right horizontally elongated window portions 8 is set to 20 mm or more, and the opening width W2 of the front and rear vertically elongated window portions 10 is set to 20 mm or more. If the opening widths W1 and W2 are less than 20 mm, the first gripping rod portion 9 and the second gripping rod portion 11 cannot be grasped with gloved hands.

[0017] The hole 2 is arranged so that a pair of opposite sides 12, 12 of the hexagon of the hole 2 is in the front-to-rear direction. As shown in Fig. 5, the sides are not perpendicular to the tire traction direction Z, and the tire traction can be received in a non-perpendicular direction, so it can withstand large traction. Fig. 6 shows a comparative example, in which the sides are perpendicular to the tire traction direction Z, so the tire traction is received in the perpendicular direction, and it cannot withstand large traction, which may result in damage.

[0018] The distance L between a pair of opposite sides 12, 12 of the hexagon of the hole 2 is set to 16 mm or less. If the distance L exceeds 16 mm, there is a risk that the block pattern portion of the tire will be pinched in the opening of the hole 2. Furthermore, if the distance L exceeds 16 mm, the area of the hole 2 becomes too large and the total area of the peripheral wall portions (forming the hexagon) becomes too small, making it difficult to withstand compressive force in the thickness direction.

[0019] The hexagonal structure (honeycomb pattern) is excellent in strength against external forces, like the wall structure of a honeycomb.

[0020] As described above, the present invention is a rectangular plate in plan view, with numerous holes 2 arranged in a pattern over substantially the entire surface of the front surface 1, a downwardly inclined surface 3 in the front half of the front surface 1, a scoop portion 5 formed in the front half of the back surface 4, and no anti-slip protrusions formed on the front surface 1, so that a large scoop is not required and space can be saved when kept in a vehicle. Furthermore, when used as a scoop, the front surface 1 does not get caught and can be used smoothly.

[0021] Furthermore, the strength is improved by forming a middle plate portion 6 that closes each of the holes 2 at the middle position in the thickness direction, and the middle plate portion 6 also receives snow and mud on rough roads, preventing the rough road escape tool for vehicles from becoming buried in the rough road.

[0022] In addition, left and right horizontally elongated window sections 8 are provided near the rear end edge 7, the rear end edge 7 is left in place to form a first horizontal gripping rod section 9, a pair of front and rear vertically elongated window sections 10, 10 are provided at the midpoint between the front and rear, and a second vertical gripping rod section 11 is formed between the pair of front and rear vertically elongated window sections 10, so that when used as a shovel, work (such as snow removal) can be easily performed by holding the first gripping rod section 9 and the second gripping rod section 11 with both hands.

[0023] Furthermore, since the first gripping rod portion 9 and the second gripping rod portion 11 are arranged below the front surface 1, when the first gripping rod portion 9 and the second gripping rod portion 11 are gripped and used as a shovel, injuries to the hands can be prevented.

[0024] Furthermore, the opening width W1 of the left and right horizontally elongated window sections 8 is set to 20 mm or more, and the opening width W2 of the front and rear vertically elongated window sections 10 is set to 20 mm or more, so that the first gripping rod section 9 and the second gripping rod section 11 can be easily and securely gripped even with gloved hands.

[0025] Furthermore, the planar shape of the hole 2 is formed as a hexagon, and the hole 2 is arranged so that a pair of opposite sides 12, 12 of the hexagon are in the front-to-rear direction, so that the tire traction can be received in a direction that is not perpendicular to the tire traction direction Z, and the hole 2 can withstand large traction.

[0026] Furthermore, the planar shape of the hole 2 is formed as a hexagon, and the distance dimension L of a pair of opposite sides 12, 12 of the hexagon is set to 16 mm or less, so that the block pattern of the tire is less likely to become caught in the opening of the hole 2, thereby improving the structural strength.
