Description

[Detailed description of the invention] The present invention relates to a standing signboard and a bossa display device.

BACKGROUND OF THE INVENTION Billboard and poster display devices of various shapes and sizes are used today to display advertising and informational messages to people passing by. Known devices include display panels permanently attached to walls or pillars, standing signboards that are simply left unfixed, and large multi-purpose devices that are heavy and difficult to store and move (both fixed and unidentified). This extends to panel equipment.

The present invention has a minimal number of parts (therefore no wear and tear or scavenging damage), is easy to handle and store (folds into a compact, easy-to-transport package), and
To provide a standing signboard device that is lightweight, sturdy, and aesthetically pleasing.

Signs that serve this purpose are in considerable demand today. This standing sign has a longitudinal slit for easy folding, and its strength is increased by the interlocking tongue and groove structure. The tongue and groove also improve the appearance and weather resistance of the sign.

The present invention is based on the invention filed by W. Farme and handed over to the assignee of the present invention.
U.S. Patent Application No. 337.gn 5tandJ.
It is more than the billboard disclosed in No. 720.

The standing sign of the present invention includes a unitary extruded tubular material bent or formed into a structure having an upright frame portion and two elongated legs or pace members. This structure allows the legs to be spread apart to provide a steady pace for displaying the sign, and can also be folded toward each other to form a compact padded case for transport and storage. A two-sided panel for the display is lowered from or attached to the frame portion for display within the frame portion.

When the billboard is "opened" for display, the two legs are spread out almost parallel, creating a steady pace. Collapsible brackets attached to the two leg members are used to hold the legs in the "open" position.

When the standing signboard is not on display, it is folded into a small, compact shape and stored. In this state, 2
The two legs are moved into positions next to each other or overlapping each other.

Mutually locking tongues and grooves are formed in the tubular material by extrusion molding or the like, and these form a seam along the slit. The tongues and grooves should have open slits so that only the seams are visible.

Thus, the present invention provides a more aesthetic appearance than the prior art. Furthermore, when the tongues and grooves match, the torsional strength of the standing signboard is increased and the intrusion of dust and water is prevented. The ability to slit the entire length of the extruded sign before bending the tubular material eliminates the extra manufacturing step of cutting twist relief slots. Thus, the signboard of the present invention can be manufactured very economically.

These and other objects, features, benefits and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

Referring to the embodiment of the invention shown in FIGS. 1-4, a sign or boss display device 10 comprises a tube 12 which is preferably hollow and formed in the shape shown. Tube 12 is preferably constructed from a metallic material, such as steel, aluminum, etc., but may also be constructed from a sturdy plastic material, such as polystyrene. The outer surface of tube 12 preferably has
It is coated or baked to provide weather resistance or an attractive appearance. Tube 12 may be bent or formed into the shape shown in any conventional manner known in the art for forming metal tubes or bending plastic tubes.

The tube 12 is formed with a pace section 14 and an upright frame section 16. The pace part 14 has two legs UI8, 2.

28.

As can be seen in the drawing, these members 18, 20° 24.
26 and 28 are all made of one piece of material and are joined by rounded or curved corners of 3°.

Display panel 32 is centrally suspended from rectangular frame 16 in the preferred embodiment shown in FIGS. 1-3. This panel 32 has two flat surfaces for displaying messages and the like. Panel 32 is preferably made of sheet metal, such as sheet aluminum, but may be made of any material that is thin, lightweight, strong, and capable of having a poster or other message mounted or printed thereon. .

The panel 32 is suspended from the upper crossbar 28 of the seven-lay entry by a pair of hinges 34. These hinges are attached to the crossbars by fasteners and extend through openings 38 in the panel. Nogunel 32 power 1 frame 1
When suspended freely from the ground, it hangs almost perpendicular to the ground, allowing the two advertising surfaces to be optimally displayed to passersby.

The present invention attaches the panel 32 to the frame portion 16,
It was understood that it was not limited to a particular method of hanging it from there). Although LJ, another method is described in the above-mentioned US patent application Ser. No. 637,720. In addition, various methods known to those skilled in the art can be used.

The tube 12 has three continuous slits 40 formed along its entire length by extrusion molding or the like. When the tube 12 is formed into the shape shown, the slit 40 is preferably located along the inner circumference of the frame structure. Referring to FIG. 5, it is shown that there is a slit 40 on the inner periphery of the rounded or curved corner 30. When this knot C is formed into the shape shown, the tube 1 becomes one piece.
2 to allow the torsional force present in the pipe to be released and to allow the signboard to be easily moved to the open/close position without causing permanent deformation of the pipe.

4 and 4a, a cross-section of tube 12 is shown, along with slit 40, which is the first and presently preferred embodiment. FIG. 4a is an enlarged view of the slit 40.

Tube 12 has a generally V-shaped groove 70 along a first edge 72 of slit 40 . Along the second edge 74 of the slit 40 is a tongue T6, which tongue has a nearly square cross section that corresponds to the figure 7 groove 70.

As used herein, the term V-shape includes a rounded 7-shape or a U-shape. In this connection, No. 4 blffl shows a second embodiment of the invention, in which the groove 70' and the tongue 76' have a rounded 7 or U shape. FIG. 40 shows yet another embodiment in which the groove 70 is generally figure-7 shaped and the tongue 76 has a rounded figure-7 or U-shape. Here, FIGS. 4a to 4
aQl simply represents the six possible tongue and groove shapes as fi
It is understood that other shapes are possible without departing from the spirit of the invention.

The tongue piece 76 and the groove 70 engage with each other to open the slit 40.
to form a seam 78 adjacent to the . The tongue piece and the groove are mutually locked to each other at A as shown in FIG.
The movement force of one end (either one of the tongue-forming end 74 and the groove-forming end 72) is 1 (becomes restrained by the power end). This &yo occurs when tube 12 is deformed by sufficient torsional force. This interlocking effect does not impair the role of the slit 40 in releasing torsional forces present in the tube. The interlocking tongues and grooves provide additional torsional strength to the tube 12 when the tube 12 is deformed to the condition shown in FIG. It also tends to stay consistent. Seam 713 formed by interlocking tongues and grooves! It exhibits the appearance of a single, neat line and does not show any gaps or openings for foreign matter to enter.

The two leg members 18.20 are approximately parallel to each other. Second

When the sign is in its "open" position and ready for display as shown in FIG.

The folding bracket 22 is attached to the leg member by a pair of fasteners 42. The bracket 22 is of conventional design and includes a pair of collapsible arms 44 and 46 connected by a pivot mechanism 48. When the signboard is closed and stored, the bracket 22 assumes its folded state and lies over and along the two leg members 1B, 2Q (see FIG. 2.6). When the sign is opened, the brackets are in a straight position and serve to hold the two leg members apart (see Figure 1). For this purpose, a locking mechanism 49 is attached to the own end of the arm 44.

Brackets 22 also limit the distance that the leg members can extend;
This prevents the standing sign from being inadvertently spread out.

The ends of the two leg members 18,20 are sealed with caps or plugs 50 to provide a "finished" appearance and to prevent dirt, water, and other foreign matter from entering the tube. The bottom of the leg members 18.20 is provided with small plastic or rubber base mounts or "feet" 52. These legs 52 may suffer from scratches or scratches on the bottom of the leg members.
This prevents the standing signboard from being damaged and being dragged along the ground by strong winds. Palast or weights (not shown) may be loaded inside the leg members 18.20 to increase the stability of the sign in windy conditions.

The foregoing description is merely illustrative of embodiments of the invention. Various changes may be made in the arrangement and manufacturing details of the illustrated embodiment without departing from the spirit or scope of the invention.
