    • A collection, storage and dispensing system for shopping carts including an elongated tubular conduit sized to allow a shopping cart to rollably pass therethrough. The conduit includes a sloped first end section defining an entrance opening through which shopping carts enter the system, a generally horizontal mid section, and a sloping second end section which defines an exit opening through which shopping carts exit the system. The mid section is preferably buried below grade, but may also be elevated above a parking lot surface of a store for vehicles to drive beneath, A floor is provided within the conduit atop which shopping carts roll. An elongated slender guide engaging probe is connected to each shopping cart which both laterally guides the carts by slidably engagement into a guide channel longitudinally in the floor and is pullably engaged onto a chain-type conveyor in one end section which is upwardly sloped. The entrance opening is positioned at grade level of a store parking area while the exit opening is positioned within the store at floor level. A denester interactive with each of the probes is provided as the carts tend to wedge together. Multiple entrance openings are provided, along with an optical comparator to insure that only proper shopping carts enter the system.
    • 用于购物车的收集,储存和分配系统,包括细长的管状导管,其尺寸允许购物车可滚动地通过。 导管包括倾斜的第一端部分,其限定了购物车进入系统的入口,通常水平的中间部分,以及限定购物车通过其离开系统的出口的倾斜的第二端部。 中间部分优选地埋在低于等级的位置,但是也可以在商店的停车场表面上方升高,以便车辆行驶到下方。一个地板设置在购物车滚动的顶部的导管内。 连接到每个购物车的细长引导接合探针连接到每个购物车,两个购物车通过在地板上纵向滑动地接合到引导通道中而横向地引导推车,并且在向上倾斜的一个端部中可拉动地接合到链式输送机上。 入口处位于商店停车区的档位级别,而出口处位于商店内的楼层。 随着推车趋向于楔合在一起,提供与每个探针交互的减震器。 提供多个入口,以及光学比较器,以确保只有适当的购物车进入系统。

    • A safety belt retracting mechanism having constant pull includes a rotatable spool for storing the belt inside a housing. A conventional, positive coefficient of force spring inside the housing applies a retracting force to the spool and belt as the belt is pulled by the occupant. The spring is coupled between the housing and spool through a variable gear ratio gear train having a negative coefficient of force transfer characteristic. The negative transfer characteristic of the gear train compensates for the positive characteristic of the spring to provide constant pull to the belt between fully retracted and fully protracted belt positions. Three embodiments of the invention are disclosed. In one embodiment, the changing gear ratio is produced by a pair of oppositely oriented cone gears connected respectively to the spring and to a spindle supporting the belt spool. The cone gears are coupled together with a traversing pinion that lowers the force gear ratio of the cones as the belt is protracted by the occupant. In another embodiment, an approximately semicircular sector gear is mounted eccentrically on a shaft whereby the effective radius of the sector gear varies as a function of sector angle. The spindle is coupled to the spring (1) through a small radius portion of the sector gear when the belt is fully retracted, and (2) through progressively larger radius portions as the belt is protracted by the occupant providing the changing gear ratio. In a third embodiment, the gear train includes a pair of enmeshing sector gears and a number of intermediate spur gears. Each of the sector gears has an elliptical surface portion. When the belt is in a fully retracted position, the sector gears are oriented with the major axes thereof coincident to each other. As the belt is protracted, the enmeshing sector gears are each rotated by a maximum of 90.degree.. Output shafts are attached to the sector gears at corresponding sides thereof and on the major axes. A continuously decreasing gear ratio provided by the elliptical surface portions of the sector gears as the belt is protracted produces the negative coefficient of force transfer characteristic of the gear train.
