  • Patent number: 5749673
    Abstract: A safety delineator is provided which includes a conical body portion to which is attached one or more vertical panels. A new and improved handle feature permits easy and comfortable full hand gripping of the delineator and also prevents sticking and jamming together of a plurality of the delineators when they are stacked. The delineators may be stacked without removing the vertical panels, since each vertical panel is particularly designed to wrap around the conical body portion to which it is attached as another vertical delineator slides over it.

  • Patent number: 5732911
    Abstract: A legless sign stand includes a rubber base having an upper planar surface and a lower planar surface. A first rigid planar member contacts the upper planar surface of the rubber base, and a second rigid planar member contacts the lower planar surface of the rubber base. Both of the rigid planar members are secured to the rubber base with bolts. Two support brackets are mounted to the first rigid planar member, and a support mast is connected between the two support brackets. The support mast accommodates a clamping member, which is adapted for clamping onto a portion of the highway traffic sign to thereby support the highway traffic sign above a horizontal support surface.

  • Patent number: 5624092
    Abstract: An adjustable bracket is disclosed for use in mounting a display sign, equipment, or the like on the post of a support stand, which is quick and easy to use, requires no tools, is easy to fabricate, and is adaptable to posts of different sizes and shapes. When installed, it is adapted to firmly grip the post along three lines of contact, thereby firmly securing the bracket at a predetermined location. An improved flexible sign receiving portion for such a bracket is also disclosed, which permits a flexible sign to be installed therein in a single motion, and provides a secure attachment of the sign to the sign stand, even in adverse conditions.

  • Patent number: 5611509
    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.

  • Patent number: 5560732
    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.

  • Patent number: 5540007
    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.

  • Patent number: 5446984
    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.

  • Patent number: 5201599
    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.
