Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the conventional tire stopper, when trying to install the vehicle stopper member between the tire and the ground, the operator has to perform the installation work in a posture of bending or lowering the waist. Moreover, the same posture has to be taken when adjusting the interval between the vehicle stopper members, and for example, it is difficult to install tire stoppers on a large number of vehicles in a short time.

Means for Solving the Problems

[0006] Therefore, the present invention provides a tire stopper that can improve work efficiency by facilitating installation on a vehicle.

[0007] A tire stopper according to one aspect of the present invention is a tire stopper for restricting the rotation of a vehicle tire, comprising: a pair of stopper bodies placed on the ground and spaced apart from each other so as to be able to face the tire tread from the front and rear sides of the vehicle; and a connecting body connecting the pair of stopper bodies, wherein, with the stopper bodies positioned facing the tire, the vehicle's height direction is defined as the stopper height direction and the vehicle's front-rear direction as the stopper length direction, the connecting body comprises: a pair of support parts that support each of the stopper bodies and are spaced apart from each other in the stopper length direction; and a connecting part positioned above the stopper body in the stopper height direction and extending in the stopper length direction, connecting the pair of support parts, wherein the connecting part has a spacing adjustment mechanism for adjusting the spacing between the pair of support parts in the stopper length direction.

[0008] In the above-described tire stopper, the spacing adjustment mechanism may be a mechanism that extends or retracts the connecting portion in the direction of the stopper's length.

[0009] In the above-described tire stopper, the connecting portion of the connecting body may be provided with a scale that indicates the approximate distance between the pair of support portions in the length direction of the stopper.

[0010] In the above-described tire stopper, each of the pair of support portions in the connecting body may have a height adjustment mechanism for adjusting the position of the connecting portion in the stopper height direction.

[0011] In the above tire stopper, when the stopper body is positioned opposite the tire, and the width direction of the vehicle is defined as the stopper width direction, each of the pair of support parts in the connecting body is: The stopper may have a lower region that extends inclined outward in the width direction of the stopper as it moves upward from the stopper body in the height direction of the stopper, and an upper region that is continuous with respect to the lower region in a bent or curved manner and extends in the height direction of the stopper.

[0012] In the above-described tire stopper, when the vehicle width direction is defined as the stopper width direction with the stopper body positioned opposite the tire, each of the pair of support parts in the connecting body may extend upward in the stopper height direction from a position offset outward in the stopper width direction with respect to the center position in the stopper width direction of the stopper body.

[0013] In the above-described tire stopper, when the vehicle width direction is defined as the stopper width direction with the stopper body positioned opposite the tire, each of the pair of support portions in the connecting body may have a lower region extending outward from the stopper body in the stopper width direction, and an upper region that is continuous with respect to the lower region by bending or curving and extends in the stopper height direction.

[0014] In the above-described tire stopper, the connecting body is positioned below the connecting portion in the height direction of the stopper and may further have an auxiliary connecting portion that connects a pair of support portions to each other, or a pair of stopper bodies to each other. [Effects of the Invention]

[0015] The above-mentioned tire stopper makes it possible to improve work efficiency by simplifying installation on the vehicle. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. (Overall Configuration) As shown in FIG. 1, the tire stopper 100 of the present embodiment is used to regulate the rotation of the tire T when the vehicle C is parked or stopped, and includes a pair of stopper bodies 1 placed on the ground and a connecting body 2 connecting the pair of stopper bodies 1.

[0018] Here, the vehicle C is a small work vehicle such as a forklift, for example, and the tire T is a solid tire that does not contain air and is called a so-called non-pneumatic tire. The tire stopper 100 of the present embodiment will be described as being installed on the rear wheels of the forklift. Since the rear wheels of the forklift are steering wheels, wear progresses quickly, and usually, they are used until the tire diameter becomes considerably smaller than that of a new tire.

[0019] (Stopper body) The pair of stopper bodies 1 are positioned at a distance from each other in the stopper length direction D1, which is the front-to-rear direction of the vehicle C, when installed on the vehicle C. Each stopper body 1 is placed on the ground in contact with or close to the tread of the tire T so that it can be faced from the front and rear sides of the vehicle C.

[0020] Furthermore, each stopper body 1, when viewed from the side in the stopper width direction D2, which is the width direction of the vehicle C, has a roughly trapezoidal or roughly triangular shape. Specifically, in this embodiment, as shown in Figure 2, the stopper body 1A provided on the front side has a tire-facing surface 1a on its outer surface that slopes toward the side of the rear stopper body 1B (hereinafter referred to as one side) in the stopper length direction D1 as it moves downward in the stopper height direction D3, which is the height direction of the vehicle C. In addition to this tire-facing surface 1a, the front stopper body 1A also has a top surface 1b, a bottom surface 1c, a back surface 1d, and a pair of side surfaces 1e on its outer surface.

[0021] The top surface 1b extends from the upper edge of the stopper height direction D3 on the tire-facing surface 1a to the other side in the stopper length direction D1, opposite to the one side mentioned above. The bottom surface 1c extends from the lower edge of the stopper height direction D3 on the tire-facing surface 1a to the other side in the stopper length direction D1 and is the surface that contacts the ground. The back surface 1d is the surface that connects the top surface 1b and the bottom surface 1c in the stopper height direction D3. The pair of side surfaces 1e are surfaces that are connected to the tire-facing surface 1a, the top surface 1b, the bottom surface 1c, and the back surface 1d on both sides in the stopper width direction D2.

[0022] The stopper body 1B (see Figure 1) located at the rear is identical to the stopper body 1A located at the front, but with the front and rear directions of the stopper length D1 reversed compared to the stopper body 1A.

[0023] (connector) As shown in Figures 3(a) to 3(c), the connecting body 2 is a member that connects a pair of stopper bodies 1, and in this embodiment, it is made by assembling resin pipes to form a gate shape. Specifically, the connecting body 2 has a pair of support parts 21 that support the pair of stopper bodies 1 respectively, and a connecting part 22 that connects the pair of support parts 21.

[0024] (Support part) Each of the pair of support parts 21 is rod-shaped and is spaced apart from each other in the stopper length direction D1. The front support part 21A of the support parts 21 extends straight from the top surface 1b of the front stopper body 1A in a direction perpendicular to the bottom surface 1c of the stopper body 1A, i.e., in the stopper height direction D3. The support part 21A is connected to the top surface 1b at the center of the stopper width direction D2 on the stopper body 1A, i.e., at the center of the stopper width direction D2 on the top surface 1b.

[0025] Similarly, the rear support portion 21B of the support portion 21 extends straight from the top surface 1b of the rear stopper body 1B in a direction perpendicular to the bottom surface 1c of the stopper body 1B, i.e., in the stopper height direction D3. The support portion 21B is connected to the top surface 1b at the center position in the stopper width direction D2 of the stopper body 1B, i.e., at the center position in the stopper width direction D2 of the top surface 1b.

[0026] (Connection part) The connecting portion 22 is rod-shaped and positioned above the stopper body 1 in the stopper height direction D3, and in this embodiment in particular, it is positioned above the tire T. One end of the connecting portion 22 is connected to the upper end of the support portion 21A, and the other end is connected to the upper end of the support portion 21B. The connecting portion 22 and the support portions 21A and 21B may be connected by a joint, or the connecting portion 22 and the support portions 21A and 21B may be integrally formed as a gate-shaped member.

[0027] Furthermore, the connecting portion 22 has a spacing adjustment mechanism that adjusts the distance between the support portion 21A and the support portion 21B in the stopper length direction D1. In this embodiment, the spacing adjustment mechanism is a mechanism that extends or retracts the connecting portion 22 itself in the stopper length direction D1. Specifically, the connecting portion 22 has an outer tube 22a, an inner tube 22b inserted inside the outer tube 22a, and a wing bolt 22c that is provided so as to penetrate the outer tube 22a and abuts against the outer surface of the inner tube 22b. By changing the amount of insertion of the inner tube 22b into the outer tube 22a and restricting the relative movement between the outer tube 22a and the inner tube 22b with the wing bolt 22c, the length of the connecting portion 22 is adjusted, and the distance between the pair of support portions 21 is adjusted. In this embodiment, the support portion 21A is connected to the outer tube 22a and the support portion 21B is connected to the inner tube 22b, but the arrangement of the outer tube 22a and the inner tube 22b may be reversed in the stopper length direction D1.

[0028] Furthermore, the outer surface of the inner tube 22b of the connecting section 22 is provided with a scale M that serves as a guide for the length dimension of the connecting section 22 (i.e., the distance between the pair of support sections 21). The scale M corresponds to, for example, the length dimension of the connecting section 22, the amount of wear of the tire T, or the outer diameter dimension of the tire T. In addition, scales M based on two or more different scales may be displayed together.

[0029] (Effects and Benefits) As described above, the tire stopper 100 of this embodiment connects a pair of stopper bodies 1 by a connecting body 2 having a connecting portion 22 extending in the stopper length direction D1, and the distance between the pair of stopper bodies 1 can be adjusted by adjusting the distance between the pair of support portions 21 using the spacing adjustment mechanism of the connecting portion 22. Therefore, the user can move the pair of stopper bodies 1 at once by gripping the connecting portion 22, and install the pair of stopper bodies 1 on the tire T at once without bending or lowering their waist. Moreover, the user can easily adjust the distance between the pair of stopper bodies 1 according to the size of the tire T by operating the spacing adjustment mechanism of the connecting portion 22 which is positioned at a high position, without bending or lowering their waist.

[0030] Since the installation of the tire stopper 100 can be made easier in this way, work efficiency can be improved when the tire stopper 100 needs to be installed on multiple vehicles C.

[0031] Furthermore, in this embodiment, the spacing adjustment mechanism for the connecting portion 22 is a mechanism that extends and retracts the connecting portion 22 itself in the stopper length direction D1, making it very easy to adjust the spacing between the pair of stopper bodies 1.

[0032] Furthermore, since the connecting portion 22 is provided with a scale M, even in cases where the tire size changes significantly due to tire wear, such as with a forklift, the distance between the pair of stopper bodies 1 can be easily adjusted in accordance with this change in tire size.

[0033] Herein, the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, the spacing adjustment mechanism for the connecting portion 22 may be a mechanism that slides the support portion 21 in the stopper length direction D1 relative to the connecting portion 22, and it is sufficient that the spacing between the support portions 21 can be adjusted.

[0034] Furthermore, the support portion 21 and the connecting portion 22 may each be plate-shaped rather than rod-shaped.

[0035] Furthermore, as shown in Figure 4, each support portion 41 may have a height adjustment mechanism for adjusting the position of the stopper in the height direction D3 of the connecting portion 22. Specifically, each support portion 41 has an outer tube 41a, an inner tube 41b inserted inside the outer tube 41a, and a wing bolt 41c provided so as to penetrate the outer tube 41a and in contact with the outer surface of the inner tube 41b as a height adjustment mechanism.

[0036] The length of the support portion 41 is adjusted (the support portion 41 expands or contracts) by changing the insertion amount of the inner tube 41b into the outer tube 41a and restricting the relative movement between the outer tube 41a and the inner tube 41b with a wing bolt, thereby adjusting the height position of the connecting portion 22. The support portion 41 may also be provided with a scale to indicate the height position of the connecting portion 22. The height adjustment mechanism may also be a mechanism that slides the connecting portion 22 in the stopper height direction D3 relative to the support portion 41, and it is sufficient that the height position of the connecting portion 22 can be adjusted.

[0037] As shown in Figure 5, the support portion 51 may also have a lower region 51x that extends inclined outward in the vehicle width direction, which is outside the stopper width direction D2, as it moves upward toward the upper side of the stopper height direction D3 from the central position in the stopper width direction D2 of the stopper body 1 (the central position in the stopper width direction D2 on the top surface 1b), and an upper region 51y that is continuous with the lower region 51x. The upper region 51y is continuous with respect to the lower region 51x in a bent or curved manner and extends straight in the stopper height direction D3. That is, the lower region 51x is inclined away from the vehicle C, and the upper region 51y extends straight in a direction perpendicular to the bottom surface 1c of the stopper body 1.

[0038] By providing this inclined lower region 51x, the connecting body 2 will not interfere with the vehicle C even when the stopper body 1 is installed in a position further inward in the vehicle width direction.

[0039] As shown in Figure 6, the support portion 61 may extend upward in the stopper height direction D3 from a position offset to the outside of the stopper width direction D2, which is outside the vehicle width direction, relative to the center position in the stopper width direction D2 of the stopper body 1. By providing the support portion 61 at an offset position on the stopper body 1 in this way, interference between the connecting body 2 and the vehicle C can be avoided even if the support portion 61 extends straight without bending (or curving) along its length. The support portion 61 may also be bent (or curved) at a position along its length, as shown in the support portion 51 in Figure 5.

[0040] As shown in Figure 7, the support portion 71 has a lower region 71x that extends outward from the outer side surface 1e in the vehicle width direction toward the outside in the stopper width direction D2, and an upper region 71y that is continuous with the lower region 71x so as to bend or curve and extends in the stopper height direction D3. That is, the lower region 71x extends straight toward the stopper width direction D2 away from the vehicle C, and the upper region 71y extends straight toward a direction perpendicular to the bottom surface 1c of the stopper body 1. By adopting such a support portion 71, interference of the connecting body 2 with the vehicle C can be avoided.

[0041] As shown in Figure 8, the connecting body 2 may also have an auxiliary connecting part 82 positioned below the connecting part 22 in the stopper height direction D3, which connects the pair of support parts 21. The auxiliary connecting part 82 is rod-shaped or plate-shaped and extends in the stopper length direction D1. The auxiliary connecting part 82 has a spacing adjustment mechanism (extension mechanism) similar to the connecting part 22. The auxiliary connecting part 82 may be integrally formed with the support part 21, or it may be connected to the support part 21 by a joint. As shown in Figure 9, the auxiliary connecting part 92 may be provided between the pair of stopper bodies 1, connecting the pair of stopper bodies 1. By adopting such auxiliary connecting parts 82 and 92, the rigidity of the connecting body 2 can be improved, and the work of carrying and installing the tire stopper can be made easier.

[0042] Furthermore, the support parts 21, 41, 51, 61, 71 and the auxiliary connecting part 92 may be detachably attached to the stopper body 1 by being inserted into and connected to holes h (see Figure 9) formed in the stopper body 1. This allows the tire stopper 100 to be easily assembled and disassembled.

[0043] Furthermore, the above embodiments and their variations may be combined as appropriate. [Industrial applicability]
