The disclosed invention generally pertains to a collapsible sign. More specifically, the invention pertains to a Ninja Sign having an open arm span that is substantially larger than that of the closed arm span, thus allowing the open frame to hold a much larger sign face than the closed frame; it also allows the sign frame to be stored and transported more easily. The face of the sign can be made to collapse as well thus further reducing the over-all size of the stored sign. Among other uses, the Ninja Sign is great for residential and commercial real estate agents, and it is not limited to outdoor applications.
In many instances companies or individuals like to take advantage of yard space to advertise various campaigns, sales, or business related events; often times this is done via transportable signs. Yard signs come in all shapes, and designs, but what is important for most signs are the aesthetics, elevation height of the face, and ease of use. Signs that are too low can become hidden by grass, or small bushes that render the sign less useful, while a lack of aesthetics can often times indicate a lack of professionalism of the company or individual that it is advertising. Most yard signs are bulky and hard to fit in the average size vehicle; they can be inconvenient to reuse because they are not compact enough to store efficiently for the next use. Thus, many larger signs simply have a one-time use.
It is quite common for business personnel, such as real estate agents, to have to set up multiple yard signs on a daily basis. To do so, the signs must first be transported to the selected site, which typically requires that the agent try and fit several large signs in their vehicle without causing scratches or dents. Simply placing multiple signs in a vehicle can allow for the signs to rattle against each other making it very difficult to communicate with clients that are in the vehicle with you, and causing damage to the signs. Not to mention that the size of the sign is often times very limited by the size of the vehicle carrying it.
Once at the desired location, the sign must either be set on the ground and left, which means that the sign must be heavy enough to not blow away, or it must have stake(s) that go into the ground. The heavier sign obviously makes it less user friendly, while putting stake(s) in the ground can be rough on the sign frame; this is because often times the stake(s) are part of the sign frame itself with no direct hitting point except for the top of the sign frame. Thus putting the stake(s) in hard ground can require that you hammer on the frame, which causes unwanted damage. Not to mention that many signs require additional tools that take up space, and inconvenience the user.
Many yard signs are large which can require the user to maintain a storage shed. Often times, in the real estate industry, yard signs are simply left outdoors leaning against the company building simply because the signs are not compact enough to store inside without a shed.
It is desirable to provide an easy to use sign that can be more conveniently stored, in the form of a Ninja Sign. Although Ninja Signs come in multiple sizes, the design can allow for the user to transport over 10 commercial size signs in the average size trunk. Ninja Signs can be aesthetically pleasing, and easy to see due to their elevated face height. They are designed to be hammered into hard ground using the frame as a post driver. The frame is also designed to make it easy to remove the stake from the ground by using the frame as a reverse post driver. Thus, no additional tools are required. Although, the Ninja Sign is great for outdoor use, it is not limited to outdoor applications.
The disclosed invention pertains to a transportable sign that is compact for storage, and easy to use. There are many variations of the design and this brief summary of the invention is not intended to limit the scope of the invention in any way, as it is merely exemplary.
A Ninja Sign comprising a rigid, spanning member approximately the length of a sign face in height (length referring to vertical length of the face). At one end of the spanning member is a housing assembly, and at the other end there is a mounting device for mounting the spanning member to a hard floor in a vertical position (both the housing assembly and the mounting device are described below, along with other components of the Ninja Sign). A spanning member can be hollow, thus being able to accommodate a stake that can be extended out the mounting device end of the spanning member. Two flanges, one on the inside of the spanning member near the mounting device, and the other on the stake near the top, can prevent the stake from being completely removed from the spanning member. Thus, the stake can be partially extended out the spanning member and pinned such that the extended portion of the stake is the desired length for inserting into the ground. The pin prevents the stake from going all the way back inside the spanning member.
The Ninja Sign would ideally have two arms, each comprising a first arm component, and a second arm component (an arm can be just a first arm component). The second arm components can be approx. the length of the spanning member, and in a closed position they can appear on opposite sides of the spanning member while extending from the mounting device to the housing assembly. A first arm component connects a second arm component to the housing assembly; it can do so such that each second arm component can rotate relative to its respective first arm component, and each first arm component can rotate about a point on/in the housing assembly. The pivot point between a first arm component and a second arm component will partly determine the sign face height and size as explained below: for conceptual purposes it is safe to make this point slightly lower than the center of a second arm component. The second arm components can be connected at their respective ends to the housing assembly and mounting device to secure them in a closed position.
The housing assembly holds the arms to the spanning member such that the arms and spanning member can lie within a small variation of a common plane in the open, and/or closed position(s). The housing assembly can be part of the spanning member, or it can be a separate component. The arms, housing assembly, and mounting device should each be symmetrical about a line parallel to, and through the center of the spanning member in a closed and open position. They should also be minimal in size, and compact to reduce storage space.
A mechanical system can connect the first arm components of the arms such that when one first arm component rotates relative to the spanning member, the other one rotates an equal amount in the opposite direction. Thus the two first arm components maintain a common angle relative to the spanning member. This mechanical system can consist of a set of congruent, interlocking gears in/on the housing assembly; each gear attached to a first arm component and centered at the point of rotation of each respectively. Thus when one first arm component rotates, the interlocking gears cause the other first arm component to rotate an equal amount in the opposite direction.
The mounting device can be used to mount the spanning member to a hard surface in a vertical position. In many outdoor applications, where the Ninja Sign cannot be mounted to a hard surface, the stake can be extended from the spanning member and pinned. The frame (comprising the spanning member, and arms) can then be used as a manual post driver for inserting the stake into the ground.
After the spanning member is firmly mounted vertically, the ends of the second arm components can be disconnected from the housing assembly and mounting device thus allowing the arms to rotate about their respective points in the housing assembly. The first arm components can be rotated to a horizontal position and temporarily secured in place from below (allowing them to rotate up but not down), while the two second arm components are able to move independent of each other until the face(s) are attached. Rectangular sign face(s) can then be mounted on the frame by attaching each top corner of each face to one end of a different second arm component (housing assembly end). One bottom corner (common side) of each face can then be attached to the mounting device end of its respective second arm component, thus we have 3 of the 4 corners of each face mounted on the arms. The 4th corner of each face can be attached to the remaining end of the second arm component by rotating each second arm component to as vertical of a position as the face will allow. Holding the remaining end of the second arm component and pushing it towards the spanning member will cause the first arm components to rotate, while bringing the mounting device ends of the second arm components closer together, and thus allowing you to attach the 4th corner of the face(s) to the frame. After connecting the 4th corner of a face, and letting go, the weight of the arms pull the face(s) taunt.
To remove the Ninja Sign, press one end (mounting device end) of a second arm component towards the housing assembly and disconnect the face(s) at that end. Lower the arms by allowing respective end of the second arm component to slowly move away from the spanning member which will cause the arms to lower. Disconnect the face(s) from the frame and secure the respective ends of the second arm components to the housing assembly and mounting device. Disconnect the mounting device from the floor if applicable. If applicable, use the frame as a reverse post driver to hammer the stake out of the ground. Then remove the stake pin and slide the stake back inside the spanning member. Thus the ( ) is in the closed position.
Some of the many advantages of the invention over prior art can include, but are not limited to: not needing any tools to set up the Ninja Sign, reducing storage space, making it easier to reuse and transport signs, improved elevation height of the face(s), and the ability to put a sign up that is taller than you physically are.
The following detailed description of the invention is simply exemplary and is not intended to limit the scope, application, or use of the invention. Neither the background of the invention, brief description of the drawings, nor the following detailed description of the invention are intended to be binding or limiting in any way as there are many variations of the Ninja Sign.
A spanning member 1 can be constructed out of steel square tubing cut to the proper length. A housing assembly can be constructed by utilizing a set of small side plates 5; each side plate having four holes 6 and 12 can be cut out with a laser and positioned at opposite sides of one end of the spanning member 1 such that that they extend past its end. A jig can be used to properly align the holes 6 and 12 of the side plates such that a line through the center of a hole 12 in one side plate 5, and passing through the center of its respective hole 12 in the other side plate 5, is perpendicular to the spanning member 1. The side plates 5 can then be welded into position.
Another set of small side plates 9, with two holes 10 each, can be constructed and attached to the other end of the spanning member 1 in a similar fashion. In the space between these two plates 9, there can be a spacer 16 on each side of the spanning member 1 for bolting the frame to a floor. Such a spacer 16 can be constructed by shearing sections of stock steel and punching a hole 17 near the center. The spacers 16 can then be welded between the two plates 9 thus forming a brace that can bolt to a hard surface to hold the spanning member 1 vertical. Small strips of thin steel can be welded inside the spanning member 1 near the brace thus creating a flange 19 as shown in
A stake 13 can be partly constructed out of a steel tube with small strips of steel welded all the way around one end to form a flange 18 as shown in
A first arm component 2 can be constructed out of steel square tubing with holes drilled at each end. An end of the first arm component 2 attaching to a housing assembly 1 can be slightly bent allowing it to curve further over the top of the spanning member 1 as shown in
Each second arm component 3 can then be positioned such that one end is positioned between the two plates 5 of a housing assembly, and the other end is positioned between the two plates 9 of a brace. A pin can then be inserted through the outer most holes 6 of a housing assembly and a second arm component 3, along with a pin through a brace and the same second arm component 3, thus securing the second arm component 3 to a spanning member 1 at both ends. Likewise, the other second arm component 3 can then be secured to the spanning member 1 as well.
A first arm component 2 can now be attached to a second arm component 3 via a pin through the hole at one end of the first arm component 2, and the remaining hole of the second arm component 3. A first arm component 2 should be positioned such that it lies between the two square tubes of a second arm component 3 and is separated from the second arm component 3 on each side by a washer. A steel gear 8 cut with a laser can then be placed on each side of a first arm component 2, centered with the hole. The gears 8, and a first arm component 2 can then be pinned through the inner holes 12, between the two side plates 5 of the housing assembly. Washers may be needed to take up any extra space between the gears 8 and side plates 5. The other first arm component 2 can then be attached in a similar fashion such that the set of gears 8 through one pin are interlocking on the set of gears 8 on the other pin.
Once the arm components are attached and in the closed position, the gears 8 can be welded to their respective first arm components 2 thus forcing one first arm component 2 to rotate relative to the spanning member 1 when the other first arm component 2 does. The pins securing the first arm component 2 to the housing assembly, along with the pins connecting the first arm component 2 and the second arm component 3 can now be welded in place to prevent them from falling out. Everything can then be cleaned for painting.
A sign face 14 can be constructed of a banner material with printing on one side. For additional strength, Power Tape can be applied to the back side of a face 14. Four grommets 15; one at each corner can be used to hold the face(s) 14 to an open frame. The same four pins used to hold the arms in a closed position can be used to hold the face(s) 14 to the frame by inserting a pin through a grommet 15 in one face 14, then back into the hole in the second arm component 3, and then through a grommet 15 in the other face 14.
A Ninja Sign can be mounted to a solid surface by placing a bolt through the top end of each hole 17 and threading it through a solid surface to secure the Ninja Sign in a vertical position.
A Ninja Sign can be mounted in the ground by extending stake 13 out the brace end of spanning member 1. A pin through stake 13 is then inserted to prevent stake 13 from sliding all the way back inside spanning member 1, as shown in
After securing a Ninja Sign frame in a vertical position (See
A face 14 can be attached to the arms of a Ninja Sign by inserting a pin through a grommet 15 in the face 14, and then inserting it into hole 7 in a second arm component 3. Repeat this with hole 7 of the other second arm components 3, and hole 11 of one second arm component 3 as shown in
Thus we have one face 14 attached to a Ninja Sign frame. If a second face 14 is desirable, start at the position shown in
While holding one of the second arm components 3 near hole 11, apply a small force towards the housing assembly; such force should be just enough to remove pressure on adjacent corner of face 14. Remove adjacent pin, thus freeing that corner of the face(s) 14. Proceed to allow the second arm components 3 to slowly lower by reducing the amount of force applied towards the housing assembly. Once the arms are down, proceed to remove the pins that are securing the face(s) 14 to the arms. Roll the face(s) 14 around a small shipping tube to preserve shape and prevent unnecessary wrinkles. Pin the arms in closed position by reinserting the pins through holes 6 and 7, and 10 and 11 respectively.
If the Ninja Sign was mounted to a solid surface, simply remove the bolts through the brace to remove the sign. If the Ninja Sign was mounted using stake 13, use the frame as a reverse post driver to remove stake 13. This can be done by ramming the frame up until it is stopped by flange 18 of stake 13 hitting flange 19 in the spanning member 1 (see
There are a wide variety of sign designs considered prior art; none of them having means of inserting a stake into, and removing a stake from, the ground. Additionally, none of them collapse into a compact position that is convenient to fit in a vehicle without having a disconnected arm component that can get lost. It is desirable to provide a commercial or residential size sign that collapses to fit in a vehicle, doesn't require any tools, holds against significant wind speeds, and is simple to use, in the form of a Ninja Sign.
