摘要： The frame comprises separate frame members joined together to form a rectangular structure for receiving a display device such as a placard. A bracket having a pair of legs forming a right angle is provided at each corner of the frame to secure the frame members together. Each frame member has a pair of oppositely disposed, longitudinally extending grooves on the rear side which receive the legs of the brackets. A screw is provided on each leg of the brackets. Each screw has an enlarged head which clamps against a lip portion on the frame members to fasten the brackets to the frame. The upper frame member is utilized to mount the adjustable hanging clip. The adjustable hanging clip has upwardly and downwardly extending projections. The downwardly extending projection is received in the lower groove. The upwardly extending projection is depressible downwardly for insertion into the upper groove. A hanger structure is provided on the clip and is spaced rearwardly from the projections so that it will not have to extend above the frame. The positionment of the hanger member results in a lever action from the point of securement of the hanger structure to the frame resulting in the frame tending to rotate towards the support structure on which the hanger is secured. This prevents stress being applied to the depressible upwardly extending projection. The clip is slidable along the frame member to permit centering.

摘要： A privacy screen or movable barrier including a plurality of base support members and a curtain. Each of the base support members including a base, a plurality of legs that are pivotably connected to the base, and a post that extends outward from the base. The curtain includes a plurality of frame members and at least one panel connected between the frame members. Each frame member includes a proximal portion configured to mate with the post of a respective base support member, and a distal portion that is hingedly connected to the proximal portion. In a deployed state of the base support members, the legs extend radially outward from the base, and in a non-deployed state of the base support members, the legs extend axially parallel with the post. In a deployed state of the curtain, the distal portion is unfolded relative to the proximal portion, and in a non-deployed state of the curtain, the distal portion is folded relative to the proximal portion.

摘要： A graphic display apparatus including a substrate including a first major surface and a second major surface, the substrate configured to transmit light when the graphic display apparatus is in a transmissive mode and reflect light when the graphic display apparatus is in a reflective mode; a reflective layer positioned on the first major surface of the substrate; a tint layer positioned on the second major surface; a diffuser layer including an image that is positioned on the tint layer such that the diffuser layer and the substrate sandwich the tint layer; and a light source located proximate the diffuser layer such that the light source and the diffuser layer sandwich the image, wherein, when the graphic display apparatus is in the transmissive mode, the light source illuminates the image such that the image is viewable from the first major surface of the substrate, and when the graphic display apparatus is in the reflective mode, the image is not illuminated by the light source and is not viewable from the first major surface of the substrate.

摘要： A collapsible and deployable sign system includes a support tube and a sliding member longitudinally slidable on the support tube. A handle is rotatably connected to the support tube and rotatably linked to the sliding member such that rotation of the handle slidably displaces the sliding member with respect to the support tube. A bracket assembly is fixed to the support tube. At least one scissoring assembly including first and second scissoring links is rotatably connected together by a rotational fastener. The first scissoring link is rotatably connected to the bracket assembly and separately to a corner brace member. The second scissoring link is rotatably connected to the sliding member and separately to the corner brace member. Handle rotation moves the sliding member toward the bracket assembly moving the corner brace member from a stowed condition proximate the support tube away from the support tube to a deployed condition.

摘要： A sign mounting adapter system includes a hitch extension tube. A sign orientation post connected and oriented perpendicular to the hitch extension tube has a longitudinal axis. A sign support post is axially and rotatably received on the sign orientation post. The sign support post has a longitudinal axis co-axially aligned with the sign orientation post longitudinal axis, and a receiving bore perpendicular to the sign support post longitudinal axis. Multiple orientation bores extend through the sign orientation post, each oriented at a first angle to proximate orientation bores and perpendicular to the orientation post longitudinal axis. A retention assembly is releasably and co-axially received in the receiving bore and one of the orientation bores. The retention assembly releasably connects the sign support post to the sign orientation post to permit selection of a sign support post axial angle of rotation to the sign orientation post.

摘要： A warning flag deployment system includes a mount having a closed bracket having a contact wall. A rod positioning member has a stowed retention wall and a deployed retention wall angularly oriented to the stowed retention wall. An open bracket has an open bracket leg and a standoff leg spacing the open bracket leg from a surface of the mount defining plane. A flag support rod is connected to the mount and is rotatable between a stowed condition and a deployed condition. The stowed condition has the flag support rod positioned between the contact wall and the stowed retention wall of the rod positioning member. The deployed condition has the flag support rod positioned between the rod positioning member deployed retention wall and the standoff leg and at least partially in a cavity defined between the plane and the open bracket leg.

摘要： A portable sign stand with wheels or rollers, an adjustable weighted base member, and a sign display member. The base member has one or more compartments so that liquid or solid ballast can be added to stabilize the sign stand in windy conditions. The upper and lower wall members of the otherwise hollow base member are joined together at one or more locations where the sign display member is connected to the base member. The base member can be made by blow molding techniques. Wheels are provided on one edge of the base member in order to allow the sign stand to be rolled and easily moved to different positions. Axle members secure the wheels to the base member. One or more resilient members can be used to connect the sign display member to the base member.

摘要： A display frame having a divider for subdividing the display area. The display frame includes a plurality of frame sections forming a rectangular perimeter around a backing member. A divider is selectively located within the display area and releasbly secured by clamps on each end for subdividing the display area. The divider may be located in a horizontal, vertical or angular configuration. Alternately, the divider may be rotated substantially parallel with the frame section so as to be positioned in a stowed location.
