By the forward and reverse rotation operations of the rotation operation member, it is configured to allow or disable the insertion between each insertion convex portion of the anti-slip member and each concave groove portion of the rotation operation member, and is configured to prevent the anti-slip member from detaching from the floor board member by the selection operation that disables the insertion. Therefore, each anti-slip member can be easily assembled to the floor board member, the rotation operation of the rotation operation member can be easily performed, the structure of the fixing mechanism can be simplified. Further, in the invention according to claim 4, the piece member is formed from a fitting base portion that can be fitted into the concave groove portion of the rotation operation member and a fitting end portion that can be fitted into the V-shaped gap between adjacent opposing surfaces on the front side portions of the one member and the other member of the anti-slip member when the operation selection that cannot be inserted into the rotation operation member is made. Therefore, the structure of the piece member can be simplified.

[0011] Further, in the invention according to claim 5, since the floorboard member, the anti-slip member, and the rotation operation member are made of paperboard, it is possible to reduce the weight, simplify, and reduce the cost of the floorboard member, the anti-slip member, and the rotation operation member. Further, in the invention according to claim 6, since the rotation operation member is formed in a laminated manner from a paperboard having the same thickness as the floorboard member, it is possible to make the paperboard of the floorboard member and the paperboard of the rotation operation member common, and reduce the cost.

[0012] Further, in the invention according to claim 7, since the V-shaped corner portion of the planar cross-shaped anti-slip member is disposed on the floorboard member at a position facing the outer peripheral surface of the tire, the kicking and locking action between the tire and the anti-slip member can be surely performed, and the tire can be easily removed. Further, in the invention according to claim 8, since a plurality of anti-slip members are scattered and arranged on the floorboard member, it can be applied to wide double tires such as medium and large trucks, and the anti-slip between the anti-slip member and the double tire can be surely performed, the application range can be expanded, and the flexibility of use can be enhanced.

It is provided with a fixing mechanism K for fixing each anti-slip member 2... to the floor plate member 1. As the fixing mechanism K, the anti-slip member 2 is formed in a planar cross shape, and a cross groove portion 1a into which the planar cross-shaped anti-slip member 2 can be inserted is formed in the floor plate member 1. A rotation operation member 3 for fixing the anti-slip member 2 to the floor plate member 1 is rotatably provided, and a piece member 4 for restricting the rotation operation of the rotation operation member 3 is provided, which constitutes an automobile tire removal tool W.

[0015] Also, in this case, the floor plate member 1, the anti-slip member 2, and the rotation operation member 3 are made of cardboard material. Also, the anti-slip uneven portions D... are formed in a triangular mountain shape on both the front and back end surfaces of each anti-slip member 2.... The anti-slip uneven portions D... are omitted in Figs. 2, 5, 14, 17, and 20 for the sake of clarity of the drawings. Also, in this case, as shown in Figs. 5, 22, and 23, the V-shaped corner V of the planar cross-shaped anti-slip member 2 on the floor plate member 1 faces the outer peripheral surface of the tire T, that is, the escape direction Q of the automobile Q 1 The anti-slip members 2 are arranged at positions facing each other. Further, in this case, as shown in Figs. 1 and 2, a plurality of anti-slip members 2... are arranged in a staggered manner on the floor plate member 1. Also, in this case, as shown in Figs. 1 and 24, the floor plate member 1 is formed with a bending portion 1b, a relief hole portion 1c, and a handle hole 1d that enable the floor plate member 1 to be bent.

[0016] Also, in this case, although not shown, the rotation operation member 3 is formed in a laminated shape from a cardboard material having the same plate thickness as the floor plate member 1.

[0017] Also, in this case, as shown in FIGS. 6, 7, and 12, the anti-slip member 2 is composed of two members, a one-side member 2a and the other-side member 2b. Slit grooves 2as and 2bs that can be mutually fitted are formed on the opposing end faces of the one-side member 2a and the other-side member 2b. By fitting the slit grooves 2as and 2bs of the one-side member 2a and the other-side member 2b, the anti-slip member 2 is formed in a planar cross shape. Also, in this case, as shown in FIGS. 6, 9, 11, 12, and 13, fitting side groove portions 2ag and 2bg are formed on both outer end faces of the one-side member 2a and the other-side member 2b of the anti-slip member 2. Fitting hole portions 3a that can be rotationally fitted to the fitting side groove portions 2ag and 2bg are formed in the rotation operation member 3. Insertion convex portions 2ad and 2bd that can be inserted into the cross groove portion 1a of the floor board member 1 are formed on the front side portions of the fitting side groove portions 2ag and 2bg of the one-side member 2a and the other-side member 2b of the anti-slip member 2. Blocking convex portions 2ae and 2be that cannot be inserted into the cross groove portion 1a of the floor board member 1 are formed on the back side portions of the fitting side groove portions 2ag and 2bg of the one-side member 2a and the other-side member 2b of the anti-slip member 2. Concave groove portions 3b·· into which the insertion convex portions 2ad and 2bd on the front side portions of the one-side member 2a and the other-side member 2b of the anti-slip member 2 can be inserted are formed on the inner peripheral surface of the fitting hole portion 3a of the rotation operation member 3 so as to correspond to the position of the cross groove portion 1a. In this case, four are formed. The dimension L 1 is formed to be substantially the same size as the hole diameter of the fitting hole portion 3a of the rotation operation member 3. The dimension L 2 is formed to be substantially the same size as the dimension between the concave groove portions 3b·· of the rotation operation member 3. The dimension L 3 is the dimension L between the outer end portions of the insertion convex portions 2ad and 2bd 2It is formed to have substantially the same dimensions as the outer diameter of the rotation operation member 3 that is larger, and by the forward and reverse rotation operations of the rotation operation member 3, it allows the insertion of each insertion convex portion 2ad·2bd of the anti-slip member 2 and each concave groove portion 3b·· of the rotation operation member 3, or it is configured to enable a selection operation that makes the insertion of each insertion convex portion 2ad·2bd of the anti-slip member 2 and each concave groove portion 3b·· of the rotation operation member 3 impossible, and it is configured to prevent the separation of the anti-slip member 2 from the floorboard member 1 by the selection operation that makes the insertion impossible.

[0018] Also, in this case, as shown in FIGS. 5, 9, and 10, when the operation selection for the rotation operation member 3 is impossible to insert, the piece member 4 is formed from a fitting base portion 4a that can be fitted into the concave groove portion 3b·· of the rotation operation member 3 and a fitting end portion 4b that can be fitted into the V-shaped gap C between adjacent opposing surfaces on the front side portions of one member 2a and the other member 2b of the anti-slip member 2.

[0019] That is, first, as shown in FIG. 11, the one member 2a and the other member 2b are assembled by fitting into the respective slit grooves 2as·2bs, and as shown in FIG. 12, the anti-slip member 2 composed of the one member 2a and the other member 2b is formed. Next, as shown in FIG. 13, the anti-slip member 2 is inserted into the cross groove portion 1a of the floorboard member 1. At this time, the blocking convex portions 2ae·2be of the one member 2a and the other member 2b face the back surface of the floorboard member 1, and the separation of the anti-slip member 2 to the surface side H of the floorboard member 1 is blocked. Next, as shown in FIGS. 14, 15, and 16, the fitting hole portion 3a and the four concave groove portions 3b·· of the rotation operation member 3 are inserted into the respective insertion convex portions 2ad·2bd of the one member 2a and the other member 2b of the anti-slip member 2. Next, as shown in FIGS. 17, 18, and 19, the rotation operation member 3 is rotated approximately 45 degrees. As a result, the floorboard member 1 and the rotation operation member 3 are sandwiched between the insertion convex portions 2ad·2bd and the blocking convex portions 2ae·2be of the anti-slip member 2. Next, as shown in FIGS. 20 and 21, the piece member 4 is fitted into the V-shaped gap C and the piece member 4 is adhesively fixed to the floorboard member 1, thereby preventing and restricting the unexpected rotation of the rotation operation member 3, and a plurality of the anti-slip members 2·· are securely fixed to the floorboard member 1 by the fixing mechanism K. As shown in FIGS. 1, 2, and 3, the automobile tire removal tool W is formed.

[0020] Also, in this case, for the above floorboard member 1, a standard size of paperboard material, for example, manufactured by Hokuriku Corporation, with a board thickness of 2.4 mm and a density of 1.13 g / cm 3 ~1.21 g / cm 3 , having a tensile strength (longitudinal) of 98.8 MPa to 107.5 MPa and a tensile strength (transverse) of 56.1 MPa to 59.3 MPa, is used. Also, for the above rotation operation member 3, a standard size of paperboard material similar to the above floorboard member 1 is used, and two sheets of this paperboard material are stacked to form a laminated structure (not shown) with a board thickness of 4.8 mm. Also, for the above anti-slip member 2, for example, manufactured by Hokuriku Toyo Fiber Co., Ltd., with a board thickness of 5.4 mm and a density of 1.29 g / cm 3 , having a tensile strength (longitudinal) of 114 MPa to 121 MPa and a tensile strength (transverse) of 61 MPa to 65 MPa, is used, and two sheets of this paperboard material are stacked to form a laminated structure (not shown) with a board thickness of 10.8 mm. Of course, the above anti-slip member 2 and the above rotation operation member 3 may not be formed in a laminated structure but may have an integral structure.

[0021] Since this exemplary embodiment has the above configuration, as shown in FIGS. 1, 2, 3, 4, 8, and 22, a plurality of anti-slip members 2... are arranged on the floorboard member 1. Each anti-slip member 2... projects from the front surface side H and the back surface side B of the floorboard member 1. Anti-slip uneven portions D... are formed on both the front and back end surfaces of each anti-slip member 2..., and it is provided with a fixing mechanism K for fixing each anti-slip member 2... to the floorboard member 1. As the above fixing mechanism K, the anti-slip member 2 is formed in a planar cross shape, and a cross groove portion 1a into which the planar cross-shaped anti-slip member 2 can be inserted is formed in the floorboard member 1. A rotation operation member 3 for fixing the anti-slip member 2 to the floorboard member 1 is rotatably provided, and a piece member 4 for restricting the rotation operation of the rotation operation member 3 is provided. Therefore, when attempting to escape the automobile Q from a bad road surface such as a snowy road or a muddy area, as shown in FIGS. 22 and 23, the floorboard member 1 of the automobile tire removal tool W is laid between the tire T of the automobile Q and the road surface G. At this time, the V-shaped corner V of the planar cross-shaped anti-slip member 2 is laid at a position facing the outer peripheral surface of the tire T. By rotating the tire T of the automobile Q, the tire T presses on the anti-slip uneven portions D... of each anti-slip member 2... protruding from the front surface side H of the floorboard member 1, and the anti-slip uneven portions D... of each anti-slip member 2... protruding from the back surface side B of the floorboard member 1 are in pressure contact with the road surface G, promoting the escape running of the tire T of the automobile Q and enabling the tire T to surely escape from a bad road surface such as a snowy road or a muddy area. Also, the weight of the automobile tire removal tool W can be reduced, the flexibility of storage and use can be enhanced, the range of applications can be expanded, and the flexibility of use can be enhanced.

[0022] Also, in this case, as shown in FIGS. 6, 7, and 12, the anti-slip member 2 is composed of two members, i.e., one member 2a and the other member 2b. Slit grooves 2as and 2bs that can be mutually fitted are formed on the opposing end faces of the one member 2a and the other member 2b. Since the anti-slip member 2 is formed in a planar cross shape by the fitting of the slit grooves 2as and 2bs of the one member 2a and the other member 2b, the structure of the anti-slip member 2 can be simplified. Also, in this case, as shown in FIGS. 6, 9, 11, 12, and 13, fitting side grooves 2ag and 2bg are formed on both outer end faces of the one member 2a and the other member 2b of the anti-slip member 2. Fitting holes 3a that can be rotationally fitted to the fitting side grooves 2ag and 2bg are formed in the rotation operation member 3. Insertion protrusions 2ad and 2bd that can be inserted into the cross grooves 1a of the floor board member 1 are formed on the front side portions of the fitting side grooves 2ag and 2bg of the one member 2a and the other member 2b of the anti-slip member 2. Blocking protrusions 2ae and 2be that cannot be inserted into the cross grooves 1a of the floor board member 1 are formed on the back side portions of the fitting side grooves 2ag and 2bg of the one member 2a and the other member 2b of the anti-slip member 2. Concave grooves 3b·· into which the insertion protrusions 2ad and 2bd on the front side portions of the one member 2a and the other member 2b of the anti-slip member 2 can be inserted are formed on the inner peripheral surface of the fitting hole 3a of the rotation operation member 3 so as to correspond to the position of the cross grooves 1a. In this case, four are formed. By the forward and reverse rotation operations of the rotation operation member 3, the insertion of each of the insertion protrusions 2ad and 2bd of the anti-slip member 2 and each of the concave grooves 3b·· of the rotation operation member 3 is allowed, or a selection operation that makes the insertion of each of the insertion protrusions 2ad and 2bd and each of the concave grooves 3b·· impossible is configured. Since the anti-slip member 2 is configured to be prevented from detaching from the floor board member 1 by the selection operation that makes the insertion impossible, each anti-slip member 2·· can be easily assembled to the floor board member 1, the rotation operation of the rotation operation member 3 can be easily performed, and the structure of the fixing mechanism K can be simplified. Also, in this case, as shown in FIGS. 5, 9, and 10, the piece member 4 is formed from a fitting base portion 4a that can be fitted into the concave groove 3b·· of the rotation operation member 3 and a fitting end portion 4b that can be fitted into the V-shaped gap C between adjacent opposing surfaces on the front side portions of the one member 2a and the other member 2b of the anti-slip member 2 when the operation selection that cannot be inserted into the rotation operation member 3 is made. Therefore, the structure of the piece member 4 can be simplified.

[0023] Also, in this case, since the floor board member 1, the anti-slip member 2, and the rotation operation member 3 are made of cardboard, it is possible to reduce the weight, simplify, and reduce the cost of the floor board member 1, the anti-slip member 2, and the rotation operation member 3. Also, in this case, although not shown, since the rotation operation member 3 is made of cardboard having the same thickness as the floor board member 1, and in this case, is formed in a laminated state by two cardboard sheets, it is possible to make the cardboard of the floor board member 1 and the cardboard of the rotation operation member 3 common, and cost reduction can be achieved.

[0024] Also, in this case, as shown in FIGS. 5, 22, and 23, since the anti-slip member 2 is arranged at a position where the V-shaped corner V of the planar cross-shaped anti-slip member 2 confronts the outer peripheral surface of the tire T on the floor board member 1, the kicking and locking action between the tire T and the anti-slip member 2 can be surely performed, and the escape of the tire T can be easily performed. Also, in this case, as shown in FIGS. 1 and 2, since a plurality of anti-slip members 2... are arranged in a staggered manner on the floor board member 1, it can also be applied to wide double tires such as medium and large trucks, and the anti-slip between the anti-slip members 2... and the double tire can be surely performed, the application range can be expanded, and the flexibility of use can be enhanced. Also, in this case, as shown in FIGS. 1 and 24, since the floor board member 1 is configured to form a bending portion 1b that enables the bending of the floor board member 1, the automobile tire removal tool W can be bent and folded when not in use such as during storage, and the flexibility of use can be enhanced.

[0025] Note that the present invention is not limited to the above-described embodiment examples, and can also be applied to various automobiles Q, for example, automobiles Q such as ordinary automobiles, trucks, light automobiles, medium-sized automobiles, and large-sized automobiles. The structure and form of the anti-slip uneven portion D, the fixing mechanism K, the floor board member 1, the anti-slip member 2, the rotation operation member 3, and the piece member 4 are designed by appropriately changing them.

[0026] As described above, the intended purpose can be fully achieved.
