    • A braking system primarily intended for use in a cargo-carrying cart of conventional type having a swivel caster at the front and rear ends and a pair of wheels rotatable upon a stationary axle extending across the longitudinal midpoint of the cart. The system includes a brake assembly inwardly adjacent each of the two wheels, each assembly having a rotor affixed to one end of a hollow, cylindrical a hub with a plurality of notches extending axially into the other end. The rotor and hub are rotationally coupled to the cart wheels by the wheel spokes extending into the hub notches. Inboard and outboard brake plates are positioned on opposite sides of each rotor. A pair of cables extends between the outboard brake plates on of the two brake assemblies, one on each side of a vertical plane through the rotational axis of the wheels, rotor and hubs. When tension is applied to one or both of these cables, the outboard plates are drawn inwardly to contact the rotors, and the rotors are moved laterally to contact the inboard plates, thereby engaging the brakes and inhibiting rotation of the wheels. In a first embodiment, the brakes are normally engaged, being disengaged to permit movement of the cart only upon operator movement of a push bar assembly to which a cable is attached for releasing tension on the brake plate cables. In another embodiment, the brakes are normally disengaged, becoming engaged upon operator manipulation of a handle assembly to which a cable is attached for applying tension to the brake plate cables. In both embodiments, the braking system is operable from either end of the cart.
    • 主要用于常规类型的携带货物的制动系统,其具有在前端和后端处的旋转脚轮,以及一对轮,其能够在延伸穿过所述推车的纵向中点的固定轴上旋转。 该系统包括向内邻近两个车轮中的每一个的制动器组件,每个组件具有固定到中空圆柱形毂的一端的转子,其具有轴向延伸到另一端的多个凹口。 转子和轮毂通过延伸到轮毂凹口中的轮辐轮旋转地联接到推车车轮。 内侧和外侧制动板位于每个转子的相对侧。 一对电缆在两个制动组件的外侧制动板之间延伸,一个通过车轮,转子和轮毂的旋转轴线在垂直平面的每一侧上。 当对这些电缆中的一个或两个施加张力时,外侧板向内拉以接触转子,并且转子横向移动以接触内侧板,由此接合制动器并阻止车轮的旋转。 在第一实施例中,制动器通常被接合,被分离以允许仅在操作者移动一个推杆组件时推动推车的移动,推杆组件附接有用于释放制动板电缆上的张力的电缆。 在另一个实施例中,制动器通常是分离的,在操作者操纵手柄组件时被接合,所述手柄组件被附接到所述手柄组件上,以向所述制动板电缆施加张力。 在两个实施例中,制动系统可从推车的任一端操作。

    • A clip or bracket releasably mountable to a rail having elongated perforations to retain one or more items in a stored position when not in use. In a simple embodiment, the clip is formed of a continuous length of metal or plastic rod having a pair of parallel legs for insertion through the mounting rail perforation, and a three-sided enclosure which, in cooperation with the surface of the mounting rail, form a four-sided enclosure for retaining the stored item. In a second, preferred embodiment, a bracket is formed with an integral, three-sided wall with one or more latching members affixed to one of the walls for releasably attaching the bracket to the mounting rail with portions of the latching member(s) extending through one of the perforations. In one form, a pair of three-sided retainers are connected to one another with latching member(s) mounted between adjacent walls of the two retainers. The invention has particular utility in the cargo transportation field where the brackets may be mounted to the conventional mounting rails currently in use in many trucks and trailers for supporting likewise conventional load bars to restrain cargo against movement during transport.
    • 可释放地安装到轨道的夹子或支架,其具有细长的穿孔,以在不使用时将一个或多个物品保持在存储位置。 在简单的实施例中,夹子由具有一对平行腿的连续长度的金属或塑料杆形成,用于插入通过安装轨道穿孔,以及与安装轨道的表面配合的三边外壳, 形成用于保存存储的物品的四面外壳。 在第二个优选实施例中,支架形成有一体的三面壁,其中一个或多个闩锁构件固定到一个壁上,用于将支架可释放地附接到安装轨道,其中闩锁构件的一部分延伸 通过其中一个穿孔。 在一种形式中,一对三侧保持器彼此连接,其中锁定构件安装在两个保持器的相邻壁之间。 本发明在货物运输领域具有特别的用途,其中托架可以安装到目前在许多卡车和拖车中使用的常规安装轨道,用于支撑同样常规的载重杆,以限制货物在运输过程中运动。

    • A user interface mechanism that introduces a novel concept referred to as a “non-overlapping workspace”. A system user can switch between the traditional overlapping workspace and the novel non-overlapping workspace, depending upon how they wish to move and manage objects in the workspace. In the non-overlapping mode, as the user moves a selected object to relocate it within the work area, as its border touches another object, the selected object pushes the other object (rather than cover it). In an alternative embodiment, when the system is in the non-overlapping mode, objects on the desktop have “sticky” borders, that is, as the border of a selected object comes into contact with the border of another object, the two objects are coupled to each other as though they were glued together, forming an “object unit”.
    • 引入被称为“非重叠工作空间”的新概念的用户界面机制。 系统用户可以在传统的重叠工作空间和新的非重叠工作空间之间进行切换,这取决于他们希望如何移动和管理工作区中的对象。 在非重叠模式下,当用户移动所选对象以将其重新定位在工作区域内时,当其边框触及另一个对象时,所选对象推动另一个对象(而不是覆盖它)。 在替代实施例中,当系统处于非重叠模式时,桌面上的对象具有“粘性”边界,即,当所选对象的边界与另一对象的边界接触时,两个对象是 彼此耦合,就像它们被粘合在一起,形成“对象单元”。
