Description

The present disclosure relates to a ring fastening device that prevents an unintended movement of a stopped vehicle.

Patent Document 1 discloses a wheel chock device provided with a wedge-shaped rotation prohibiting member arranged at a prohibited position formed in a gap between the ground and the wheel and prohibiting the rotation of the wheel. The rotation prohibition member is selectively moved to a prohibited position and a non-prohibited position where rotation of the wheel is not prohibited by the moving mechanism. The moving mechanism includes a cylinder having a cylinder shaft, and a rotation prohibition member is detachably attached to the tip of the cylinder shaft. A bracket is fixed to a mounting frame fixed to the vehicle, and the rear end of the cylinder is rotatably attached to the bracket as the cylinder shaft expands and contracts.

The tip of a long guide rod is rotatably fixed to the center of the cylinder shaft in the longitudinal direction, and the rear end of the guide rod is attached to the mounting frame so that it can rotate as the cylinder shaft expands and contracts. It is attached to a fixed bracket. The guide rod guides the cylinder shaft so that the rotation prohibition member moves from the non-prohibited position to the prohibited position.

One end of a connecting member such as a chain or a rope is connected to the upper portion of the rotation prohibiting member, and the other end of the connecting member is connected to a winding mechanism fixed to a mounting frame. By winding the connecting member by the winding mechanism, the rotation prohibition member located in the prohibited position can be moved to the non-prohibited position.

A lock mechanism is fixed to the tip of the cylinder shaft, and a catcher mechanism for attaching and detaching the lock mechanism is fixed to the rotation prohibiting member. A guide pin for guiding the lock mechanism to the catcher mechanism is formed in the lock mechanism, and the guide pin is inserted into the guide hole of the catcher mechanism.

The lock mechanism has locks arranged at four places, and the catcher mechanism has catchers engaged with the four locks arranged at four places. When the lock and the catcher are separated from each other, the lock and the catcher are firmly fixed by pressing the lock against the catcher with a predetermined force. On the other hand, when the lock and the catcher are fixed to each other, the lock is released by pressing the lock against the catcher with a predetermined force, and the lock and the catcher are separated from each other.

When moving the rotation prohibition member from the non-prohibited position to the prohibited position, the movement mechanism is driven. By driving the moving mechanism, the cylinder shaft starts to extend, the guide rod starts to rotate around the rear end portion, and the cylinder shaft is guided by the guide rod while extending, and the rotation prohibition member reaches the prohibited position. The rotation prohibition member that has reached the prohibited position is blocked by the wheels and cannot advance further, and by further extending the cylinder shaft in this state, the lock and the catcher fixed to each other are separated from each other. Subsequently, by contracting the cylinder shaft, the rotation-prohibited member and other members other than the connecting member are moved to the non-prohibited position, and the wheel is kept in a non-rotatable state.

When moving the rotation prohibition member from the prohibited position to the non-prohibited position, the movement mechanism is driven. By driving the moving mechanism, the cylinder shaft is kept in the same state, and the connecting member is wound by the winding mechanism. As a result, the rotation prohibition member moves to the non-prohibited position together with the connection member, reaches the vicinity of the tip of the cylinder shaft, the lock and the catcher are fixed to each other while the guide hole is guided by the guide pin, and the rotation prohibition member is not. It is held in the prohibited position.

Japanese Unexamined Patent Publication No. 2008-254719

Generally, the vehicle body is elastically supported so as to be able to move up and down with respect to the axle of the wheel, and the height of the vehicle body (vehicle height) with respect to the axle (wheel) and the ground fluctuates according to the load capacity (vehicle weight) of the vehicle. However, the wheel chock device of Patent Document 1 is not configured assuming fluctuations in vehicle height. For example, when the cylinder and the guide rod are set so that the rotation prohibition member moves to the rotation prohibition position when the vehicle height is a predetermined reference height, if the vehicle height is lower than the reference height, the rotation prohibition member is set. If the vehicle height is higher than the reference height, the rotation prohibition member abuts on the wheels and is prevented from moving above the rotation prohibition position. .. In this way, when the rotation prohibition member comes into contact with the ground or wheels at a position other than the prohibited position to prevent movement, a pressing force acts on the lock mechanism and the catcher mechanism from a direction different from the design direction, and rotation is prohibited with the cylinder shaft. There is a possibility that the fixing with the member will not be released smoothly. In addition, the locking mechanism and the catcher mechanism may be damaged by the pressing force acting from a direction different from the design direction. That is, the wheel fastening device of Patent Document 1 may not function effectively when the vehicle height fluctuates.

Therefore, it is an object of the present disclosure to provide a wheel fastening device for a vehicle that can be reliably functioned even when the height of the vehicle body fluctuates without requiring complicated work.

In order to achieve the above object, the first aspect of the present disclosure is a wheel fastening device for a vehicle in which a vehicle body is elastically supported by an axle of a wheel, and a first arm, a second arm, a ring fastening member, and the like. It is equipped with an arm pulling mechanism.

The first arm is arranged on one side of the wheel in the vehicle front-rear direction, and has a first base end portion and a first tip end portion at both ends. The first base end portion is rotatably supported toward the vehicle body side around the first rotation axis extending in the vehicle width direction, and the first arm can be tilted about the first rotation axis above the lower end of the wheel. be. The second arm has a second base end portion and a second tip end portion at both ends. The second base end portion is rotatably supported by the first tip end portion of the first arm about a second rotation axis extending in the vehicle width direction. The ring fastening member has a wedge shape and is rotatably supported by the second tip of the second arm about a third rotation axis extending in the vehicle width direction.

The arm pulling mechanism can pull the first arm to the first arm storage position where the first tip portion has risen to a predetermined height. When the holding by the arm pulling mechanism is released while the first arm is held in the first arm storage position, the first arm is the first arm in which the bottom surface of the ring fastening member is placed on the ground on the one side of the wheel. It tilts downward toward the other side in the front-rear direction of the vehicle with the first rotation axis as the center until the deployment position.

In the first aspect, when the vehicle is running, the first arm is held in the first arm storage position by the arm pulling mechanism. By holding the first arm in the first arm storage position, the ring fastening member is supported on the vehicle body side above the ground, and the rotation of the wheels is not blocked.

When preventing an unintended movement of a stopped vehicle, the holding of the first arm by the arm pulling mechanism is released. When the holding by the arm pulling mechanism is released, the first arm is tilted from the first arm storage position to the first arm deployment position by its own weight, and the bottom surface of the ring fastening member is placed on the ground on one side of the wheel. When the bottom surface of the ring fastener is placed on the ground and the ring fastener member is inserted downward on one side of the wheel (for example, when the ring fastener member is in contact with the outer peripheral surface of the wheel from below). ), It is not necessary to move the ring fastening member, but if the ring fastening member is not inserted (for example, when the ring fastening member is separated from the outer peripheral surface of the wheel), a worker such as an occupant may be asked. , The ring fastening member on the ground is moved by the tip of the foot or the like and inserted downward from one side of the wheel. By inserting the wheel fastening member below the wheel, the rotation of the wheel (rotation that moves the vehicle to one side) is blocked by the wheel fastening member.

The base end of the first arm is rotatably supported toward the vehicle body, the base end of the second arm is rotatably supported by the tip of the first arm, and the ring fastener member rotates to the tip of the second arm. Since it is freely supported, even if the vehicle height fluctuates according to the load capacity (vehicle weight) of the vehicle, the first arm tilts from the first arm storage position to the first arm deployment position. , The bottom surface of the ring fastener is placed on the ground on one side of the wheel. Therefore, the ring fastening member can be reliably functioned even when the vehicle height fluctuates without requiring complicated work.

When starting the vehicle, the arm pulling mechanism pulls the first arm from the first arm deployment position to the first arm storage position. When the first arm is pulled up, the wheel fastening member moves from the lower side of the outer peripheral surface of the wheel to the upper side on one side, and the rotation inhibition of the wheel is released.

The second aspect of the present disclosure is the ring fastening device of the first aspect, and the center of gravity of the ring fastening member is such that the bottom surface of the ring fastening member is suspended from the third rotation shaft. It is set to incline downward toward the other side and face the ground.
