    • A screw bar for connecting a nut member and a bearing member of a pantograph-type jack includes a cylindrical-shaped bar member having a joint portion formed integrally with the bar member at one end and a threaded portion formed integrally on the bar member at the other end. The nut member of the jack is threadably engageable with the threaded portion of the screw bar, and the bearing member of the jack is pivotally mountable on the bearing support portion of the screw bar. The maximum outer diameter of the threaded portion is less than or equal to the desired diameter of the bearing support portion so that the bearing member can be mounted on the screw bar from the threaded-portion end. Preferably, the joint portion includes a flange portion having an outer diameter greater then the desired diameter and the bearing support portion is provided with a lug portion. The lug portion and the joint portion are positioned on opposite sides of the bearing member mounted on the bearing support portion to prevent axial movement of the bearing member. A method for forming the screw bar also is disclosed.
    • 用于将螺母构件和缩放式千斤顶的轴承构件连接的螺杆包括:圆柱形的杆构件,其具有在一端与杆构件一体形成的接合部和在该杆构件上一体形成的螺纹部 另一端 千斤顶的螺母构件可螺纹地与螺杆的螺纹部分接合,并且千斤顶的轴承构件可枢转地安装在螺杆的轴承支撑部分上。 螺纹部分的最大外径小于或等于轴承支撑部分的期望直径,使得轴承构件可以从螺纹部分端部安装在螺杆上。 优选地,接头部分包括具有大于期望直径的外径的凸缘部分,并且轴承支撑部分设置有凸耳部分。 凸耳部分和接头部分位于安装在轴承支撑部分上的轴承部件的相对侧上,以防止轴承部件的轴向移动。 公开了一种用于形成螺杆的方法。

    • A pantograph jack apparatus for elevating a motor vehicle includes first and second upper arms pivotally connected to a supporting plate engageable with the motor vehicle and first and second lower arms pivotally connected to a base plate supporting the jack apparatus at ground level. The first upper arm and first lower arm are pivotally connected to a threaded connecting nut that is threaded on the threaded portion of a shaft member. The second upper arm and second lower arm are pivotally connected to a connecting bearing rotatably mounted on the non-threaded portion of the shaft member. The connecting bearing is axially movable on the shaft member between two stop portions so that, when the connecting bearing abuts against the first stop portion, the jack is in its lowered position for storage and, when the connecting bearing abuts against the second stop portion, the jack is raised to a position where it is engageable with a jacking portion of the motor vehicle body. Thus, the jack can be raised to engage the motor vehicle body without rotating the shaft member. The pantograph jack apparatus also is provided with a mechanism for preventing the jack from being lowered by gravity after it has been raised to engage the motor vehicle body.
    • 用于提升机动车辆的集电弓插座装置包括可枢转地连接到可与机动车辆接合的支撑板的第一和第二上臂,以及以地平面方式枢转地连接到支撑千斤顶装置的底板的第一和第二下臂。 第一上臂和第一下臂枢转地连接到螺纹连接螺母,螺纹连接螺母被拧在轴构件的螺纹部分上。 第二上臂和第二下臂枢转地连接到可旋转地安装在轴构件的非螺纹部分上的连接轴承。 连接轴承可在轴构件上在两个止动部之间轴向移动,使得当连接轴承抵靠第一止动部时,千斤顶处于其下降位置用于储存,并且当连接轴承抵靠第二止动部时, 千斤顶被升高到可与机动车身的起重部分接合的位置。 因此,千斤顶可以升高以接合机动车体而不旋转轴构件。 集电弓插座装置还具有用于防止千斤顶在被升高以接合机动车体之后被重力降低的机构。

    • A vehicle door opening-closing device which enables a reduction in the time for releasing a fully closed condition of the vehicle door without changing the driving force and the driving speed of the actuator when operating a vehicle door from a half closed condition to the fully closed condition and when releasing the fully closed condition. A latch mechanism includes a latch engageable with a striker and an engagement member for maintaining the latch at a condition for operating the vehicle door to the half closed condition and the fully closed condition. An operation mechanism operated by a motor operates the latch by way of a closing lever and operates the engagement member by way of an opening lever based on operation of an operation member. The opening lever possess a smaller lever ratio than the lever ratio of the closing lever.
    • 一种车门打开关闭装置,其能够在将车辆门从半关闭状态操作到完全关闭的同时减少用于释放车门的完全关闭状态的时间而不改变致动器的驱动力和驱动速度 当释放完全关闭状态时。 闩锁机构包括可与撞针接合的闩锁和用于将闩锁保持在用于将车门操作到半闭合状态和完全关闭状态的状态的接合构件。 由电动机操作的操作机构通过关闭杆操作闩锁,并且通过基于操作构件的操作的开启杆操作接合构件。 开启杆具有比关闭杆的杠杆比小的杠杆比。
