摘要： A vehicle restraint comprising a base member (e.g., a track), a carriage movably mounted to the base member, and a restraining member (e.g., a pivotable hook) mounted to the carriage and movable between and engaged position and a disengaged position. The restraining member is biased toward the engaged position. The restraining member is biased by a biasing member in the form of a gas spring operatively positioned between the restraining member and the carriage. The restraining member is pivotable, and the restraint further includes a lever interconnected with the restraining member. In this embodiment, the biasing member is interconnected with the lever to bias the restraining member toward an engaged position. The biasing member can be positioned to bias the restraining member toward the disengaged position when the restraining member is in the disengaged position and to bias the restraining member toward the engaged position when the restraining member is in the engaged position.

摘要： A wheel chocking device (13) having a wheel chock (34) that can be raised from a retracted position to a raised position. In the retracted position, the wheel chock (34) is substantially flat, thereby allowing a truck (36) to be driven over the wheel chock (34). In the raised position, the wheel chock (34) can be engaged with the wheel (36) of a truck to prevent the truck from driving away from a loading dock. In one embodiment, movement of the chock (34) is provided by pneumatic cylinders (120) that drive cables (124) or chains associated with pneumatic pistons (122) positioned within the cylinders (120). As the chock (34) is moved from the distal position, the chock (34) can raise from a lowered position to an intermediate position (3). The chock (34) is then moved toward the vehicle wheel (36). Upon contact with the wheel (36), the chock (34) will raise from the intermediate position to the fully raised position. In another embodiment, the chock (136) can be inserted laterally from the side of the wheel (36).

摘要： A method of securing a vehicle at a desired location using a wheel chocking device (30) having a chock (38) movable between a lowered position and a raised position. The method comprises the steps of positioning the vehicle at the desired location with the chock (38) in the lowered position, raising the chock to the raised position, moving the raised chock toward a wheel of the vehicle, sensing the presence of an obstruction on the vehicle, lowering the raised chock to an intermediate position to allow the chock to pass under the obstruction, and contacting the chock with the wheel. The wheel chocking device (30) includes a drive mechanism (40) that is positioned underneath the chock so that the vehicle actually drives over the drive mechanism. The drive mechanism is simplified with the use of a drive screw (152) and a partial drive nut (148, 154) that facilitates the use of support members (156) for supporting the drive screw at spaced locations along the length of the drive screw. A multi-link chock facilitates use of the device on wheels of varying sizes.
摘要翻译：一种使用具有可在降低位置和升高位置之间移动的轴承座（38）的轮胎闭塞装置（30）将车辆固定在期望位置的方法。该方法包括以下步骤：将车辆定位在所述位置处，其中所述轴承座（38）处于降低位置，将所述轴承座升高到升高位置，将所述升高的轴承座朝向所述车辆的车轮移动，感测到所述阻塞件车辆将升高的轴承座降低到中间位置，以允许轴承座在障碍物下通过，并将轴承座与车轮接触。轮撬装置（30）包括驱动机构（40），驱动机构（40）位于轴承座下方，使得车辆实际上驱动驱动机构。通过使用驱动螺钉（152）和部分驱动螺母（148,154）来简化驱动机构，该部分驱动螺母（148,154）有助于使用支撑构件（156）来沿驱动螺杆的长度的间隔位置支撑驱动螺杆。多连杆轴承座有助于在不同尺寸的车轮上使用该装置。
