Abstract: An implement attachment system for a lawn maintenance vehicle includes a box-like structure, where the box-like structure defines a hook configured to cooperate with fasteners located on the lawn maintenance vehicle. A pin is attached to the box-like structure and the pin extends generally downward from the box-like structure. The pin is configured to cooperate with an aperture defined by a portion of an associated frame located on the lawn maintenance vehicle. A resilient force member is attached to the box-like structure. An engagement device is attached to the resilient force member and the engagement device is slidingly attached to the box-like structure.

Abstract: The invention relates to a vehicle jack 12 integrated into a chassis of a vehicle 10 and comprises two jack assemblies 12.1, 12.2 arranged in end-to-end fashion along each side of the vehicle. Each jack assembly includes an elongate drive screw 20 and a pair of legs 9, one of which is pivotally connected to a screw follower 22. In addition, the jack 12 Includes a drive mechanism 14 comprising a bevel gear arrangement which is drivingly connected to the respective drive screws 20. Upon actuation of the drive mechanism 14, the pairs of legs 9 are simultaneously, pivotally displaced relative to the chassis between a retracted position, in which the legs 9 are substantially aligned and disposed at least partially within or around the chassis, thereby not to adversely affect the ground clearance, and an extended position.

Abstract: Vertical elongate support (2) for supporting a parked vehicle trailer (1), consisting of a top prop tube (21), an inner prop member (22) which can telescopically slide into the prop tube (21), and a threaded spindle (3) for moving the inner prop member (22) in relation to the prop tube (21), whereby the threaded spindle (3) meshes with a threaded bearing (31) that is secured to the upper end of the inner prop member (22). The upper end of the threaded spindle (3) is connected to a crown wheel (32), the upward-facing surface of which is part of a thrust bearing (33) or is designed to accommodate a thrust bearing (33). The thrust bearing (33) supports the vehicle trailer (1), either directly or via a cover (23) that is connected to the prop tube (21).

Abstract: A lifting device includes a jack having a first portion and a second portion movable relative to the first portion. A coupling is fixedly attached to the second portion for movement relative to the first portion, the coupling extending away from the second portion and having a configuration for selective attachment to a receiver hitch. The second portion may be moved relative to the first portion with a handle. The lifting device includes a sleeve coupled to the coupling for movement with the sleeve. Support tubing may extend through the sleeve for contact with the ground. This tubing may be locked into place relative to the sleeve. With the tubing, sleeve, and coupling locked into place, a vehicle will be upheld if the jack portions fail. The lifting device may also include a bumper attachment for raising a vehicle that does not have a receiver hitch.
Abstract translation: 提升装置包括具有第一部分和相对于第一部分可移动的第二部分的插座。 联接器固定地附接到第二部分以相对于第一部分移动，联接器远离第二部分延伸并且具有用于选择性地附接到接收器挂钩的构造。 第二部分可以用手柄相对于第一部分移动。 提升装置包括联接到联接器以与套筒一起运动的套筒。 支撑管可以延伸穿过套筒与地面接触。 该管道可以相对于套管锁定到位。 管道，套管和联轴器锁定就位，如果千斤顶部分失效，车辆将被维持。 提升装置还可以包括用于提升不具有接收器牵引的车辆的保险杠附件。
