Abstract: A quick release mechanism is provided for securing a member to a structure, such as a support leg to a sign stand, wherein the member includes a slot having a bottom surface and the structure has a slot having an open top end. A latch member releasably attaches the member to the structure, and is adapted to extend axially through both the member and structure slots, so that a proximal portion of the latch member extends forwardly of the member slot and a distal portion of the latch member extends rearwardly into the structure slot. With this arrangement, when the latch member proximal portion is actuated downwardly, the latch member distal portion swings upwardly through the open top end of the structure slot, thereby disengaging from the structure slot and releasing the member so that it may pivot relative to the structure.

Abstract: A safety delineator is provided having either a conical or a tubular body portion, which has an improved handle feature permitting easy and comfortable full hand gripping of the delineator. The invention additionally solves a longstanding problem common to prior art support bases for delineators and the like, by providing a convenient handle, molded integrally with the support base element, for picking up the base. The inventive handle not only provides a convenient means for grabbing the delineator, but it also provides an additional advantage with respect to conical delineators, in that it prevents them from sticking together when they are stacked. Two types of inventive support bases are disclosed. One is a base molded from a heavy solid material, such as rubber, and includes additional advantageous features such as anti-skid grippers on the bottom surface of the base element and stacking rings molded onto the upper surface of the base element for assisting in compactly stacking a plurality of bases.

Abstract: A regulatory flexible highway sign of rectangular configuration that may be rolled up for transport and for storage is disclosed. The rolled up "sign" package and a foldable sign stand for securing the sign in a message display position are disclosed. When the flexible highway sign is arranged in a display position, it is vertically supported by means of a pair of angularly oriented, long flexible members by a holding assembly constructed and designed to permit pivotal movement of the two flexible members between an angularly oriented sign displaying position and a side by side disassembled position whereby the pivot for the flexible members does not bear a load. The sign per se is maintained in a display position by frame members secured thereto including a pair of longitudinal members pivotably secured to the sign so that when longitudinally aligned secure the flexible sign in a display position. This is achieved by means of a sliding C-clamp member.

Abstract: A mounting bracket or socket for use with a flexible highway sign capable of being rolled up for storage and portability. The mounting bracket being molded from a non-rigid, elastic material that is reasonably transparent and having a socket for accommodating a frame member for the highway sign in a non-rotatable relationship. The plastic bracket including a securing platform integrally molded therewith for securing the bracket to the highway sign. A reinforcing member of substantially the same length as the mounting bracket for clamping the highway sign between the bracket and the reinforcing member. The sign engaging surfaces of the bracket and the reinforcing member each include tear resistant elements for clamping the sign to thereby transfer the sign tearing load from the fastener securing the bracket and reinforcing member to the highway sign.

Abstract: A two-piece, detachable traffic channelization element having an improved base element. The base element has a low profile, dome-like configuration with a ballast storage chamber. The storage chamber may be completely filled with a sand ballast and sealed in its storage condition by a cover secured to the chamber. The base element is molded of a resilient crush resistant plastic so that when it is fully ballasted, need not be ballasted again, and which low profile base can be traveled over by motor vehicles without engaging the base. The detached base, filled with ballast, can be continuously traveled on by motor vehicles, including loaded trucks, without damaging the base element and rendering it useless and the need to be replaced.

Abstract: A flexible highway safety sign capable of being rolled up for storage and portability and mounting a high-way flag. The safety sign is useful with flexible frame members that allow the mounted sign to bend in response to winds and wind gusts without tipping over and taking a set. The frame members include a clamping assembly for mounting a plurality of flag arms with the highway sign. The clamping assembly permits a pair of flag arms to be pivotally secured thereto between a flat displaying position and a storage position. The storage position allows the flag arms to assume a side-by-side relationship with the folded frame members to the sign to permit the flexible sign to be wreapped around the members for storage and/or transport.

Abstract: A traffic barricade of the A-frame type constructed of a lightweight material such as plastic to have a forbidding appearance. The barricade members are unitarily constructed to be interchangeable and with integral hinge mechanisms. The hinge mechanisms have detenting elements for improving the resistance to winds tending to cause the closure of the "A" stance of the barricade. The barricade permits a damaged hinge element to be readily replaced. Ballast may be added to a storage compartment arranged adjacent the supporting surface for the barricade. The design of the plastic barricade permits a warning light to be directly secured by a mounting bolt functioning as a hinge pin. The individual barricade members may be stacked with substantially no relative movement of the stacked members.

Abstract: A traffic channelizer mountable vertical panel molded of a resilient, impact resistant, plastic material. The vertical panel has a pair of mounting legs securable to the top of the traffic channelizer to permit the vertical panel area to extend above the channelizer. The legs are constructed so as to be bendable in response to wind forces without tipping over the channelizer and springing back to a vertical position when the bending forces subside.

Abstract: A traffic control device constructed as either a one piece or two piece device of a resilient plastic by molding. Both the one piece and two piece devices are constructed to have a ground engaging surface defined with a multiplicity of dependent elements arranged thereon in a preselected pattern for distributing the weight of any ballast means over the dependent elements so that they function as localized pressure points to more firmly engage the supporting surface to minimize their movement on the supporting surface due to wind gusts, vibrations or the like.The two piece device is constructed with a base element that not only includes the dependent elements but also skids for permitting the assembled two piece device to be slid over a supporting surface on the skids to prevent the assembled two pieces from becoming unintentionally detached while being slid.The devices are capable of being stacked with and without the warning light secured thereto and present the appearance of a formidable object.

Abstract: A traffic control device constructed as a one-piece traffic channelizing device of a plastic material. The device includes a bottom having a plurality of flexible flap elements for receiving and storing a ballast thereon. The flexible flap elements are responsive to a substantial impact to the traffic control device to cause the ballast to be released from the flexible flaps while the device is impacted to a horizontal position adjacent its original position. The device is adapted to mount warning lights and to be stacked including with the warning lights mounted thereto. The stacking of the traffic control devices does not effect the desired action for the flexible flaps.
