Since the beginning of civilization, images and text over surfaces—signs—have been used to communicate, in every form of human interaction: commerce, political speech, personal relationships, sports affiliation, etc.
When an individual wants to convey information over a space, a simple and effective way to accomplish this so is hold up a sign with your hands. However, this solution is limited both in time and space, as holding up a sign is tiring and limits mobility. This is especially true when the activity is lengthy in duration and distance: for example, the George Floyd protests and marches.
There is a need for a Hands-Free Sign Holder (100) that can be carried by a user (90) over a long distance and that allows for easy and quick sign fastening.
“rod”—a relatively long, evenly shaped piece of material, used for some mechanical purpose.
This device relates to a sign holder (100) that allows for a user (90) to carry a sign (80) in a hands-free manner. The Hands-Free Sign Holder (“sign holder”) (100) allows a sign (80) to be easily and quickly fastened onto the sign holder (100).
The sign holder (100) comprises two shoulder supported members (300), a back structure (200), one or more upright rods (400), one or more sign fasteners (600) per upright rod (400). The sign holder (100) may further comprise one or more connector assemblies (500) per upright rod (400).
The sign holder (100) allows a user (90) to carry a sign (80) that can be seen above a crowd or over large distances. The sign holder (100) can also be used for advertisement, safety warning, picketing, protesting, and tour guide group signaling. Sign types that would be suitable for the sign holder (100) include paperboard, cardboard (corrugated), plastic, cloth, and any other material on which an image or text can be applied.
The back structure (200) is rigid, providing structural support to the sign holder (100) when the user (90) wears the sign holder (100) on their back. The rigidity of the back structure (200) allows the sign holder (100) to be easily worn on a user's back; the rigid back structure (200) also allows upright rods (400) to be connected to the back structure (200) without falling or sagging.
The back structure (200) may comprise a single solid piece. Alternatively, the back structure (200) may comprise a frame (230). The frame (230) is comprised of a plurality of members (232).
The plurality of members (232) maybe arranged as outer members (250), creating a hollow frame, where the hollow frame comprises a single aperture (260).
The plurality of members (232) may be arranged as outer members (250) and inner members (240). The outer members (250) and inner members (240) may be arranged in a grid-like pattern and have a plurality of apertures (260).
Shoulder supported members (300) allow a user (90) to carry the sign holder (100) over the shoulders (92) of the user (90). The shoulder supported member (300) may be a rigid structure—e.g. a shoulder bar—or a non-rigid structure—e.g. a shoulder strap.
The shoulder supported member (300) has a first end (310) and a second end (320). The shoulder supported member (300) are attached to the back structure (200) by at least the first end (310) of the shoulder supported member (300)—e.g. a shoulder bar. The shoulder supported member (300) may also be attached to the back structure (200) by the second end (320) of the shoulder supported member (300)—e.g. a shoulder strap.
Each shoulder supported member (300) may further comprise a buckle (330) that can adjust the length of the shoulder supported member (300), allowing for a wide spectrum of users' sizes and girths.
Each shoulder supported member (300) may further comprise a shoulder pad (350). Having the shoulder supported member (300) being padded helps the user (90) carry the sign holder (100) for an extended amount of time.
The shoulder supported member (300) maybe complemented by a back pad (340). The back pad (340) is attached to either the back structure (200) or to the shoulder supported members (300). The back pad (340) allows for cushioning between the user's back and the back structure (200). This allows for extended use of the sign holder (100) by the user.
One or more upright rods (400) elevate the signs (80) above crowd level, providing increased visibility for the signs (80). The material of the one or more upright rods (400) is selected from state-of-the-art light weight materials. The length of the one or more upright rods (400) is selected to allow for a variety of elevations above crowd level. The upright rod (400) may have any state-of-the-art cross section, including but not limited to circular, elliptical, square, or rectangular.
When the sign holder comprises one upright rod (400), the upright rod (400) is normally centered widthwise on the back structure (200). However, the upright rod (400) maybe positioned at any position widthwise on the back structure (200).
When the sign holder (100) comprises two upright rods (400), the upright rods (400) are normally positioned at either end of the back structure (200), widthwise.
Each upright rod (400) has a top end (410) and a bottom end (420). The one or more upright rods (400) may be connected directly to the back structure (200). Alternatively, each of the one or more upright rods (400) may be connected to the back structure (200) by connector assembly (500).
A variety of lengths can be utilized to size the upright rod (400), depending on the desired visibility above crowd level the upright rod (400) need to elevate the sign (80).
The one or more upright rods (400) maybe telescoping, where the upright rod (400) is either in a telescoped state or in a non-telescoped state. The one or more upright rods (400) can be placed in a non-telescoped state, so that for example, the sign holder (100) can be easily transported from one place to the other, or when the displayed sign (80) only needs to be viewed at a close distance. The one or more upright rods (400) can be placed in a telescoped state so that the displayed sign (80) is seen at a longer distance. In a telescoped state, the upright rods (400) can be telescoped to various lengths.
The Connector Assembly (500) comprises a rod (510), a first end (502), and a second end (504).
One or more connector assemblies (500) may connect each upright rod (400) to the back structure (200). Preferably two connector assemblies (500) connect each upright rod (400) to the back structure (200).
The connector assembly (500) is located between an upright rod (400) and the back structure (200), where the connector assembly (500) connects the upright rod (400) to the back structure (200).
The connector assembly (500) may have either a permanent attachment to the upright rod (400) or a removable attachment to the upright rod (400). The connector assembly (500) may have either a permanent attachment to the back structure (200) or a removable attachment to the back structure (200). Examples of a permanent attachment include soldering, riveting, and gluing. Examples of a removable attachment include hooks, bolts, screws, nuts, snaps, pins, clasps, magnets, sticky substances, and clamps.
When the back structure (200) comprises a frame (230), the connector assembly (500) is connected to the frame (230).
When the back structure (200) comprises a frame (230), and the frame (230) comprises outer members (250) and inner members (240), the connector assembly (500) may be connected to either the outer members (250), the inner members (240) or both.
A specific type of connector assembly (500) with removable fasteners is the double fastener connector assembly (520). The first end (502) comprises a first fastener (530) and the second end (504) comprises a second fastener (540). The double fastener connector assembly (520) allows for quick and easy assembly and disassembly.
The first fastener (530) fastens to the upright rod (400) and the second fastener (540) fastens to the back structure (200). The type of fastener is dictated by the shape of the upright rod (400) and the back structure (200) and includes any state-of-the-art fasteners that create an removable attachment. Examples of a removable attachment include hooks, bolts, screws, nuts, snaps, pins, clasps, magnets, sticky substances, and clamps.
In an embodiment, the first fastener (530) is a rod clamp (550). The rod clamp (550) fastens to the upright rod (400). The rod clamp (550) comprises a bore (552), a threaded shaft (554), and a bolt (556). The threaded shaft (554) of the rod clamp (550) is aligned perpendicularly to the center axis of the bore (552). A upright rod (400) is placed through the bore (552) of the rod clamp (550). The bolt (556) is fastened through the threaded shaft (554) of the rod clamp (550). The thread of the bolt (556) needs to be compatible with the threaded shaft (554) of the rod clamp (550). The bolt (556) is fastened through the threaded shaft (554) of the rod clamp (550) until the bolt (556) fastens against the upright rod (400).
In this embodiment, the second fastener (540) is a J-shaped clamp (560). The J-shaped clamp (560) fastens to the back structure (200). The shape of the J-shaped clamp (560) is curved and has an open end (562), allowing the J-shaped clamp (560) to be inserted onto the back structure (200) without any back structure (200) disassembly; the J-shaped clamp (560) is useful in a number of back structure (200) configurations. The J-shaped clamp (560) comprises a threaded shaft (564) and a bolt (566). The bolt (566) is fastened through the threaded shaft (564) of the J-shaped clamp (560). The thread of the bolt (566) needs to be compatible with the threaded hole (564) of the J-shaped clamp (560).

The double fastener connector assembly (520) for each corresponding upright rod (400) are spaced out height wise to even out the forces that the upright rod (400) places onto the back structure (200). For example, when there are two double fastener connector assemblies (520) per upright rod (400), the first double fastener connector assembly (520) is fastened towards the top end of the back structure (200) and the second double fastener connector assembly (520) is fastened towards the bottom end of the back structure (200).
Sign fasteners (600) allow for the fastening of a sign (80) to the sign holder (100). Sign fasteners (600) also allow for the unfastening of the sign (80) to the sign holder (100) so that a different sign (80) can be used with the sign holder (100).
A sign fastener (600) can attach to either an upright rod (400), a cross-rod (700) or both, or a board (800).
When a sign fastener (600) is attached to an upright rod (400), one or more sign fasteners (600) are used per each upright rod (400).
A second sign fastener (600) may be attached at a point on each upright rod (400) that is lower than the point where the first sign fastener (600) is attached to. The use of two sign fastener (600) per upright rod (400) prevents signs (80) from moving and flapping around, minimizing mobility issues with the sign holder (100) or reading issues with the sign reader.
Two specific embodiments of a sign fastener (600) include ended sign fasteners (610) and L-shaped sign fasteners (650).
An ended sign fastener (610) comprises a first end (612) and a second end (614). The first end (612) of the ended sign fastener (610) is attached to the upright rods (400), preferably near the top end (410) of the corresponding upright rod (400).
The second end (614) of an ended sign fasteners (610) may comprise a means to fasten a sign (610). The means to fasten a sign (610) is attached to the second end (614) of the sign fastener (600).
The means to fasten a sign (610) is any state-of-the-art device that can be used to fasten to objects or fasten objects. These devices include hooks, bolts, screws, nuts, snaps, pins, clasps, magnets, sticky substances, and clamps. When the means to fasten a sign (610) is a sticky substance, the sticky substance is layered over (“attaches”) to the second end (614) of the ended sign fastener (610). The means to fasten a sign (610) fastens to the sign (80) and allows a sign (80) to be fastened to the sign holder (100).
Magnets are especially useful as a means to fasten a sign (610), either if the sign (80) is ferromagnetic or the magnet can attach to a ferromagnetic surface, fastening the sign (80) in between the magnet and the ferromagnetic surface.
An L-shaped sign fastener (650) comprises a regular volume (660), one or more L-shaped brackets (670), and a bolt (680). The regular volume (660) comprises a bore (662), a threaded shaft (664), a top end (666) and a bottom end (668). The regular volume (660), for example, can be a cylinder, a cube, or a rectangular prism. The bore comprises a central axis (663).
An upright rod (400) is inserted through the bore (662) of the regular volume (660) of the L-shaped sign fastener (650). The diameter of the bore (662) is such that an upright rod (400) can be inserted through the bore (662) of the regular volume (660) of the L-shaped sign fastener (650).
The threaded shaft (664) is oriented perpendicular to the bore (662), spanning from the outside of the regular volume (660) to the bore (662).
The bolt (680) is fastened into the threaded shaft (664) so that the bolt (680) can be fastened against the upright rod (400).
L-shaped brackets (670) allow for the fastening of signs (80) to the sign fastener (600). Each L-shaped bracket (670) comprises a vertical member (672) and a horizontal member (674). The vertical member (672) is oriented parallel to the central axis (663) of the bore (662). The horizontal member (674) is oriented perpendicular to the vertical member (672) of the L-shaped bracket (670) and perpendicular to the central axis (663) of the bore (662). The horizontal member (674) of each L-shaped bracket (670) is attached to the bottom end (668) of the regular volume (660), creating a gap (690) between the vertical member (672) of the L-shaped bracket (670) and the regular volume (660).
When the L-shaped sign fastener (650) comprises one L-shaped bracket (670), the sign holder (100) has a capacity of displaying the front (82) and back (84) of one sign (80). When the L-shaped sign fastener (650) comprises two L-shaped brackets (670), the sign holder (100) has the capacity of displaying either the front (82) or back (84) of two signs (80). This would be helpful when one side of the sign (80) has no useful content.
To assemble a sign holder (100) comprising L-shaped sign fasteners (650), two L-shaped sign fasteners (650) are used per upright rod (400). The bore (662) of the first L-shaped Sign Fastener (650) is placed through the upright rod (400) so that the vertical member (672) of the L-shaped bracket (670) is oriented upwards. This L-shaped sign fastener (650) is moved downwards through the upright rod (400) to a location where the bottom end (88) of the sign (80) should be placed.
The bore (662) of the second L-shaped sign fastener (650) is placed through the upright rod (400) so that the vertical member (672) of the L-shaped bracket (670) is oriented downwards. The second L-shaped sign fastener (650) is moved downwards through the upright rod (400) to a location where the top end of the sign (80) should be place. Normally this location of the second L-shaped sign fastener (650) is the top end (410) of the upright rod (400).
Both L-shaped sign fastener (650) are moved along the corresponding upright rod (400) so that the sign (80) fits snuggly between the two L-shaped sign fasteners (650), specifically the L-shaped bracket (670) of the two L-shaped sign fasteners (650). The bolts (680) of each L-shaped sign fastener (650) are fastened against the corresponding upright rod (400).
A sign holder (100) may further comprise one or more cross-rods (700).

One or more sign fasteners (600) are attached to each cross-rod (700). The cross-rods (700) maybe attached to the upright rods (400) facing forwards, facing backwards, or both, relative to the back structure (200).
The one or more cross-rods (700) are attached to the upright rods (400). One or more sign fasteners (600) for each cross-rod (700) are attached to each cross-rod (700). The cross-rods (700) are oriented perpendicular to the upright rods (400).
When the sign holder (100) comprises a single cross-rod (700), the cross-rod (700) is attached near to the top end (410) of the upright rods (400) so that the sign fasteners (600) attach to the top of the sign (80).
When the sign holder (100) comprises a plurality of cross-rods (700), each cross-rod (700) can fasten to the sign (80).
When the sign holder (100) comprises two cross-rods (700), a first cross-rod (700) is attached to the upright rods (400) so that the sign fasteners (600) of the first cross-rod (700) attach to the top end of the sign (80). A second cross-rod (700) is attached to the upright rods (400) so that the sign fasteners (600) of the second cross-rod (700) attach to the bottom end of the sign (80).
Using two cross-rods (700) for a single sign (80) prevents the sign (80) from moving and flapping around, as the two cross-rods (700) attach to the top end and the bottom end of the sign (80).
Multiple sets of two cross-rods (700) maybe attached to the upright rods (400) connected to the back structure (200). The sets of two cross-rods (700) maybe attached to the top end of the upright rods (400) or to the bottom end of the upright rods (400). The sets of two cross-rods (700) maybe attached facing forwards, facing backward or both, relative to the back structure (200).
A sign holder (100) may further comprise a board (800). The board (800) is attached to either one or more upright rods (400) or one or more cross-rods (700) or both. The board (800) is attached the upright rods (400) or the cross-rods (700) at one or more points. One or more sign fasteners (600) are attached to the board (800).
A sign (80) is placed against the board (800) and one or more sign fasteners (600) fasten the board (800) to the sign (80).
When a sign holder (100) comprises a board (800), the board (800) may be a ferromagnetic metal board (810). In this embodiment, the sign fastener (600) is one or more magnets (820). The ferromagnetic metal board (810) is attached to either one or more upright rods (400) or one or more cross-rods (700) or both. The ferromagnetic metal board (810) is attached the upright rods (400) or the cross-rods (700) at one or more points.
A sign (80) is placed against the ferromagnetic metal board (810) and the one or more magnets (820) are placed against the sign (80) so that the sign (80) is fastened between the ferromagnetic metal board (810) and the one or more magnets (820).
Each shoulder supported member (300) may further comprise one or more sign fasteners (600). Having a sign fastener (600) attached or fastened to the shoulder supported members (300) allows an additional sign (80) to be worn chest level.
For example, the one or more sign fasteners (600) can be attached to the shoulder supported members (300) at chest level, or at stomach level, or both.
