A post sleeve includes a reinforced concrete body preformed around a liner that defines a cavity extending longitudinally within the body, sized to receive a post. Standoff ribs run lengthwise within the cavity and extend inward from inner walls of the cavity. A post in the cavity is supported laterally by the standoff ribs. Drain channels between the ribs permit water to flow past the post and exit the cavity via a lower aperture. A drain tube is coupled to the lower aperture, and extends downward where it is covered with gravel at the bottom of a post hole. Concrete is poured around the post sleeve in the hole. The cavity is adaptable to receive posts of varying sizes, and at various depths. A collar closes a space between the post and the top of the cavity, permitting air circulation within the cavity while shedding water and substantially preventing insects from entering the cavity.

A post sleeve provides a substantially permanent base for supporting a post for a fence or sign, and from which one post can be removed and replaced with another post. The sleeve includes a concrete body that is poured on site, using a sleeve core prepositioned in the post hole, and around which wet concrete is poured. After the concrete is cured, the core is removed, leaving a post sleeve cavity configured to receive a post. The core can be rigid, or can include a flexible shell and stiffener. A preformed post sleeve top can be attached to the sleeve core and positioned therewith in the post hole, to become a permanent part of the post sleeve, once the concrete cures. A drain is attached to the core, and remains in the sleeve when the core is removed, and can be a percolation chamber, or passage extending below the sleeve.

A location marker is disclosed, apt for use at work sites, crime scenes, sporting events, or as a traffic control or warning device. The location marker consists of a body having and at least one upright and a base supporting the upright from below, the upright being provided with an alerting feature to alert an observer or intended recipient about a message the alerting feature intends to convey; the body including biasing means configured to urge the upright into an erect orientation after being momentarily knocked over such that the alerting feature is almost always displayed, with the upright in the erect configuration.

The modular traffic director is a temporary traffic indicator that is adapted to direct traffic through construction zones. The modular traffic director is a signaling device that is designed for visibility and that is designed with a plurality of conspicuous cylinders that project perpendicularly from the ground such that the modular traffic director is readily visible to traffic. The modular traffic director is stackable. The modular traffic director comprises a base and a plurality of conspicuous cylinders.

A traffic control marker is provided and described herein. The traffic control marker can be configured with a main marker body that is flexible and durable, the main marker body can be further configured with a reflective element that covers at least a portion of the main marker body. The main marker body can further be configured with an indentation or a channel that extends a portion of or alternatively the length of the main marker body. The reflective element is configured to be protected during a vehicle impact with the traffic control marker, such that at least a portion of the reflective element remains effective and reflective after the impact.

A traffic director includes a distal end and a proximal end, two or more sides extending upward from the proximal end at an angle toward the distal end, a proximal notch disposed near the proximal end between two adjacent sides, and the proximal notch forms a first flexion point of the traffic director. The traffic director can further include one or more recessed channels formed in at least one of the two or more sides. The one or more recessed channels forms a second flexion point of the traffic director. The traffic director can further include a removable indicator sleeve having an advertisement or directional indicator printed thereon.

A sign post assembly includes a core assembly. The core assembly includes an impact absorbing mechanism and an elongated post. The impact absorbing mechanism includes an anchoring plate including a through hole, and a first elastic impact absorber. The elongated post has a proximal end and a distal end. A flange is disposed at the distal end of the post and rests on a top surface of the first elastic impact absorber with the post extending through the through hole in anchoring plate. A dimension of an outer surface of the post is less than a dimension of an inner surface of the through hole and the flange has a peripheral shape that prevents the flange from passing through the through hole.

A mono-structure including a first layer and a second layer. The first layer has molecular continuity with the second layer. Each of the first layer and second layer have a characteristic mechanical property. The value of the characteristic mechanical property of the first layer is different to the value of the characteristic mechanical property of the second layer.
