Abstract: A bicycle trailer comprises a frame having at its one end a hitch assembly for connecting the bicycle trailer to a towing bicycle and at its other end a ground-engagable wheel. The hitch assembly comprises a clamp part for clamping non-rotatably to a seat supporting part, for example the seat post, of the towing bicycle, a universal joint portion fixedly attached to the trailer frame and a releasable fastening attaching the clamp part to the universal joint portion. The universal joint portion permits pivoting of the trailer, in use, about generally vertical and horizontal axes which are spaced apart, preferably with the second pivot axis between the first pivot axis and the trailer frame. The clamp part may comprise a generally U-shaped member having a cylindrical bight portion and a bolt member extending through aligned holes in end portions of the U-shaped member to urge them together and clamp the seat supporting part. The holes may provide clearance for the bolt member as the end portions rotate relative to the bolt member during tightening of the bolt member. The end portions may take the form of cylinders with a cylindrical insert in each of the cylinders. The bolt member then extends through both inserts. The hole in one of the cylinders is oversized to provide clearance for the bolt member during rotation of the insert about its axis as the bolt member is tightened. The releasable fastening may comprise a non-rotatable spigot-and socket connection between the clamp member and the universal coupling portion, and retainer for retaining the spigot in the socket.

Abstract: A tow bar assembly for use in connecting a towing vehicle to a towed vehicle. The tow bar assembly includes a drawbar and a housing assembly capable of being configured with a supplemental braking system. A connector secures the housing to a tow hitch member, such that two separate, non-planar perpendicular axes of pivotal rotation are created. The tow hitch assembly includes at least one arm with an inner and outer portion, wherein the inner portion rotates about a central axis relative to the inner portion within the outer portion. A fourth pivotal axis is created by a connection of mounting brackets to the tow hitch member.

Abstract: The single wheel trailer and stabilizing hitch assembly includes a hitch which precludes lateral tilt or roll of a trailer about the longitudinal axis of the towing vehicle and trailer, the trailer having only a single wheel for support. The hitch includes a pair of horizontal plates which bear against one another, with a vertical pivot pin securing the two plates together to allow the trailer to turn laterally relative to the towing vehicle. A separate horizontal pivot axis accommodates pitch of the trailer relative to the towing vehicle while negotiating bumps and dips. However, the trailer tongue is fixed relative to the roll axis of the assembly, and the trailer cannot tilt or lean to the side while being supported by its single wheel. This greatly reduces wheel bearing and tire wear, and reduces rolling resistance of the trailer as well. Different trailer configurations are also provided.

Abstract translation: 单轮拖车和稳定挂钩组件包括一个挂钩，其阻止拖车围绕牵引车辆和拖车的纵向轴线的侧向倾斜或滚动，拖车仅具有用于支撑的单个轮。 连接器包括一对彼此承载的水平板，其中垂直枢轴销将两个板固定在一起，以允许拖车相对于牵引车辆横向转动。 单独的水平枢转轴线可协调拖车相对牵引车辆的俯仰，同时协商颠簸和倾斜。 然而，拖车舌片相对于组件的滚动轴线是固定的，并且拖车在其单轮支撑的同时不能向侧倾斜或倾斜。 这大大减少了车轮轴承和轮胎的磨损，并降低了拖车的滚动阻力。 还提供了不同的拖车配置。

Abstract: An improved trailer assembly capable of carrying a load and having improved stability characteristics is disclosed. Specifically, in a preferred embodiment, the trailer hitch assembly has an interconnecting member pivotally connected to a first member and a second member. The interconnecting member has a longitudinal center line, relative to the first member and second member pivots. The first member is pivotally connected at its one end to the interconnecting member, wherein the first member is capable of pivoting in a horizontal direction relative to the longitudinal center line. The center member is pivotally connected at its one end to the interconnecting member, wherein the second member is capable of pivoting in a vertical direction relative to the longitudinal center line. Thus, a towed vehicle operably connected to the trailer hitch assembly, which for example is a trailer or carrier having a narrow width, is substantially restricted from rotating about a longitudinal axis during transit or during a turn, which decreases the risk of tipping and otherwise provides increased stability.

Abstract translation: 公开了一种能够承载负载并具有改进的稳定特性的改进的拖车组件。 具体地，在优选实施例中，拖车牵引组件具有枢转地连接到第一构件和第二构件的互连构件。 互连构件具有相对于第一构件和第二构件枢转的纵向中心线。 第一构件在其一端枢转地连接到互连构件，其中第一构件能够相对于纵向中心线在水平方向上枢转。 中心构件在其一端枢转地连接到互连构件，其中第二构件能够相对于纵向中心线在垂直方向上枢转。 因此，可操作地连接到拖车牵引组件（例如，具有窄宽度的拖车或拖车）的牵引车辆基本上被限制在运输期间或在转弯期间围绕纵向轴线旋转，这降低了倾翻的风险，否则 提高了稳定性。
