A sign waving machine platform for street side promotions that incorporates a base frame, a sign waving apparatus plus an upper web to attach accessories including mannequins and electric signs. The sign waving apparatus includes a motor housing, battery, electric motor and bracket assembly that couples the motor drive shaft to a sign frame which moves relative to the housing as the motor drive shaft rotates. Signs can be attached to all sides of the sign frame. The platform attaches at the top only to posts, carts and other so it can freely swing in many directions with the wind. This rugged, lightweight platform has a primary structure made from 2 aluminum tubes; one slides inside the other and telescopes. Fastening occurs using thumb screws attached to the outer tubes and joints that when twisted, pinches the inside interconnecting tubes. The platform stretches in many directions providing numerous configurations.

A display assembly that has a support, a mobile mount, a stationary mount, and a display unit. The display unit is supported by the mobile mount and the mobile mount is supported by the stationary mount which is secured to support. The mobile mount and the stationary mount are rotatable with respect to each other and may include undulating patterns that move the display vertically. The support includes a lighting element for backlighting the display and a locating element for positioning the stationary mount on the support.

A device as a moving advertising medium which can provide a message with a two- or three-dimensional sign. The device is a simple, non-fully rotatable, back and forth sign system with variable themes and message placards that are easily updated and changed. It includes an exterior vertical tubing component; an interior shaft such as a fiber glass rod with key features, a placard resembling a figure in several typified sections, a gripping frame to hold a message placard, a bearing on the rod; and way to control the back and forth movement.

A display apparatus includes a display including a front surface configured to display an image and a rear surface provided with a mounting groove. The display apparatus further includes a rotation module including at least one body that is configured to couple to the display by being inserted into the mounting groove, the rotation module further including a drive motor configured to provide a driving force to rotate the display about an axis perpendicular to the front surface and the rear surface of the display. The display apparatus further includes a bracket configured to be mounted on a stand or a wall and to which the rotation module is coupled. The display and the rotation module are configured to lock together by the display and the rotation module being coupled.

A low drag outdoor media façade display for mounting on a structure susceptible to instability when exposed to strong winds, having an array of radiating elements thinly dispersed about the façade area, held by an array of thin suspension elements, the elements are spaced apart leaving gaps, such that the total surface area of the elements is smaller than the total area of the façade display. A tilting mechanism, active or passive, is operational for tilting the façade display or at least one element thereof. The passive mechanism allows free tilt in response to wind blow, and the elements may include tails. The active mechanism is operational for altering wind load drag profile of the façade display to accommodate wind conditions. The display may be inflatable or collapsible sail-like. A display featuring a liquid spray curtain for refracting or reflecting light projections is a further measure for reducing wind load.

A reversible sign, such as a highway sign, by which either of at least two informational messages may selectively be displayed. The sign is easily reversed, so that one of the two messages is visible to oncoming viewers. The sign includes an outer frame portion in which a planar central, inner, message portion or panel is rotatably disposed. The sign is temporarily held in position to display the desired message, until the message is deliberately but easily changed by rotating the message panel. Axle assemblies are provided for rotatably mounting the message panel within the outer frame. Magnetic fasteners reliably but releasably hold the inner message panel in a desired display position in relation to the outer frame.

Airfield guidance signs are described herein. One airfield guidance sign includes a first surface, a second surface angled with respect to the first surface, and a top edge adjacent the first surface and the second surface, wherein the top edge is rounded to reduce a pressure differential between the first surface and the second surface when a force is applied to the first surface or the second surface.

The invention relates to a monitor system (10) with (h) a first monitor (12.1), (i) a second monitor (12.2), (j) a third monitor (12.3), (k) at least a fourth monitor (12.4) and (l) a base (16). According to the invention, it is intended that (m) the monitors (12.i) are fixed to the base (16) such that they can each be moved by way of a motor in at least two degrees of freedom, and that (n) the monitors are fixed to the base (16) by means of lazy tong drives.

Disclosed is a pivotable signpost support device. The device includes a signpost support that is vertically aligned with a ground post support, wherein the signpost support is disposed above the ground post support that is affixed to a ground post. The signpost support and the ground post support are secured between first vertical support and a second vertical support. The signpost support is pivotally secured to the first and second vertical supports by means of a pivot bolt having a die spring at an end thereof, so that it can pivot forward and backward relative to the first and second vertical supports. The pivot bolt can tighten the die spring so as to keep the signpost support in an upright position but allowing the signpost support to fall into a collapsed position.
