摘要： A safety barrier positionable across a path for deterring rolling objects from passing beyond the barrier includes an elongate hollow member having open lateral ends. The elongate hollow member includes a base for positioning on a surface and an upwardly extending wall having an arcuate concave surface for hindering rolling objects from passing beyond the barrier.

摘要： A traffic barrier comprises a step-like obstruction able to resist or prohibit the advance of a vehicle, a hinged platform disposed in advance of the step-like obstruction and rockable between a lowered position and a raised position, in which its trailing edge is adjacent the top of the step-like obstruction, spring means urging the platform into its raised position, latch means operable to lock the platform in its raised position to permit a vehicle to advance over the step-like obstruction, and control means including a coin-operated device or the like, for controlling the operation of the latch means.In one embodiment, the latch means is normally in its released condition, and is actuated to lock the platform in its raised position when the prescribed parking fee is inserted into coin-operated device. The control means is responsive to advance of the rearmost wheels of the vehicle on to the top of the step-like obstruction to release the latch means and prevent advance of a following vehicle until the coin-operated device is tripped by the driver of the following vehicle.In another embodiment, the latch means is normally retained in its latched condition, and the control means is responsive to the front wheels of a vehicle approaching the platform to release the latch means if the driver of that vehicle does not insert the prescribed parking fee in the coin-operated device.

摘要： A SAFETY BARRIER IS PROVIDED TO PREVENT WRONG-WAY TRAFFIC FROM ENTERING A ONE-WAY STREET. THE BARRIER IS FORMED BY ONE OR MORE METAL PANS WHICH EXTEND TRANSVERSELY ACROSS THE ROADWAY. EACH PAN IS HINGED TO THE ROADWAY ON ITS LONGITUDINAL SIDE WHICH IS FIRST ENCOUNTERED BY VEHICLES MOVING IN THE NORMAL DIRECTION OF TRAFFIC FLOW. SPRING MEANS ARE PROVIDED UNDERNEATH THE PAN FOR NORMALLY HOLDING THE PAN IN AN ANGLED, ELEVATED POSITION. THE OTHER, NORMALLY ELEVATED LONGITUDINAL EDGE OF THE PAN IS PROVIDED WITH A DOWNWARDLY TURNED FLANGE WHICH IS CLEARLY VISIBLE TO TRAFFIC APPROACHING FROM THE WRONG DIRECTION, AND GIVES THE APPARATUS OF A CURB.

摘要： A traffic control device, for use with a roadway receiving vehicles travelling longitudinally along the roadway, includes a housing mounted transversely across the roadway with an upper supporting surface that supports the vehicles rolling over the housing. A tire puncturing frame comprised of a shaft supporting tire puncturing members thereon is rotatable within the housing between stored and working positions of the tire puncturing members relative to the upper supporting surface of the housing. Offset counterweights are coupled to the frame to bias the tire puncture members towards the working position. A latch bolt threaded into a threaded aperture in the housing selectively retains the tire puncturing frame in the stored position.

摘要： Ramp-guard for placement on roadways preventing wrong-way travel. Includes a base having a center cutout, and screw holes utilized to attach base to concrete frame. Extending upward from the base is tensioning spring having horizontal section lying flat upon base at traffic entering end. Spring is bent upward at angle which angular section passes through base cutout. The end of angular section of spring contacts ramp and applies upward force forcing ramp up when not under vehicular weight. A warning sign is oriented vertically on the side of ramp guard device when spring is not compressed and rotates pivotally when spring becomes compressed. Ramp guard is positioned so that end with horizontal aspect of spring faces traffic entering direction. If vehicle travels onto ramp in correct direction, spring is compressed and ramp is flattened, permitting traffic flow. If vehicle enters from wrong direction, driver sees ramp and warning sign and turns around.

摘要翻译： 在道路上放置的舷梯防止错误的旅行。 包括具有中心切口的基座和用于将基部附接到混凝土框架的螺钉孔。 从基座向上延伸的是张紧弹簧，水平部分在交通进入端处平躺在基座上。 弹簧以角度部分穿过基座切口的角度向上弯曲。 弹簧接触角度部分的端部倾斜并在不在车辆重量下时向上施加强制加速。 当弹簧未被压缩并且当弹簧压缩时，警告信号在斜坡防护装置的侧面垂直地定向旋转。 斜坡防护装置的定位使得弹簧的水平方向的端部面向交通进入方向。 如果车辆以正确的方向行驶到斜坡上，则弹簧被压缩并且斜坡变平，允许交通流量。 如果车辆从错误的方向进入，驾驶员会看到斜坡和警告标志，并转过来。

摘要： A hinged curb, maintained in normally-erected position by springs, is readily folded downward by vehicular traffic moving in the intended direction, as on an exit road from a superhighway. However, if a vehicle inadvertently enters the exit road, it serves as a low barrier curb which visually warns the driver of such vehicle and if struck by the vehicle forcibly directs attention to the danger. The impact of the vehicle against such curb may be used to actuate a warning signal.
