Description




FIELD OF THE INVENTION




The present invention relates generally to signs and particularly to signs that convey a message to a pedestrian.




BACKGROUND OF THE INVENTION




Traditionally, floor signs have been used to convey messages regarding hazardous conditions. For example, floor signs have been used to inform pedestrians of hazardous or unusual surface conditions, such as wet, waxed, or newly painted floors. Floor signs typically take the shape of cones, pyramids or folding signs.




Conventional floor signs have significant disadvantages. A floor sign can pose a significant trip hazard. Also, a floor sign sometimes cannot be placed near the hazardous area. For example, floor signs may not be placed directly on stairways or steps due to the trip hazard associated therewith and due to the restrictions imposed by governing regulations in most jurisdictions that specify the required amount of unobstructed surface on each step. To warn pedestrians of a wet or slippery step, for example, floor signs must be placed directly above and/or below the affected flight of stairs. Pedestrians may not exercise appropriate care, because the floor sign cannot be placed directly in the area of concern. Furthermore, once a pedestrian has passed by the floor sign the existence of the hazardous condition may be forgotten.




Thus, there remains a need for a sign that can be positioned directly in an area containing a condition requiring a pedestrian's attention. These areas may include, for example, a wet stair, a wet floor, a hazardous condition beyond a closed door, an out of service elevator or an area in need of a directional marker, etc.




A further disadvantage associated with conventional floor signs is that the sign is typically positioned well below the field of vision of a pedestrian. As a result, the sign may be overlooked. The magnitude of the problem increases as the pedestrian moves closer to the sign. Thus, there remains a need for a sign that may be placed further from the surface being walked upon so that the pedestrian is more likely to be aware of the sign and consider the message being displayed.




Signs have previously been hung from door handles to provide information to pedestrians. In order to avoid interference with the operation of the door handle, however, these signs typically are essentially two-dimensional. As a result, a conventional door handle sign tends to blend in with the surface of the door and a pedestrian is not alerted to the presence of the sign until he is directly in front of the door. At that point the sign may be difficult to read, as it is typically flush against the door and below the door handle. Thus, there remains a need for a sign capable of being hung from a door handle that does not interfere with operation of the door handle, is easy to read, and is configured to alert pedestrians to the presence of the sign before their arrival in front of the door.




Due to the high demand for warning signs there is a need for a lightweight sign that may be packed and stored efficiently. Existing floor signs provide for folding or compacting features so that the signs may be bulk shipped or stored and several different conventional floor signs are fabricated from lightweight plastic material. However, due to the relatively large size requirements, existing floor signs may still be heavy and difficult to handle. As a result, there remains a need for a lightweight hanging sign that may be compactly stored and shipped to minimize space and shipping costs.




The present invention meet the needs set forth above, and provides other benefits as well.




SUMMARY OF THE INVENTION




According to the present invention, there is provided a hanging sign that includes a first wall having a first surface for displaying a message and a second wall having a second surface for displaying a message. The first and second surfaces may be positioned to face in generally opposing directions. The sign further includes a hook member c connected to the walls and configured to be placed about a support. The walls may be angled to improve the viewing angle for a passerby viewing the sign. The walls may be connected together at respective side edges to form a v-shaped cross-section or may be separated by a flat transition panel. The sign may include a cavity back, a hollow interior or a solid interior.




The present invention also includes a sign that may be hung from a hand railing assembly for a staircase. The sign may include a first wall for displaying information in the direction of the top of the staircase, and a second wall for displaying information in the direction of the bottom of the staircase. A hook member is configured to support the walls and to be placed about a portion of the hand railing assembly. The staircase sign may include a base wall connected to bottom edges of the first and second walls. The sign may include a cavity to permit nesting of another staircase sign within the cavity. The walls may be connected to form a v-shaped cross-section. The hook may include a further recess sized to fit around the railing assembly. The sign may also include a hollow or solid interior.




The present invention may further include a method of providing information to people moving along a railing assembly. The method includes providing a sign that has a first surface for displaying information to people moving along the railing in one direction and a second surface for displaying information to people moving along the railing in a second direction substantially opposite to the first direction, and a hook member for hanging the walls from the railing assembly by placing the hook member on the railing assembly. According to the present invention, the method may include placing the sign above a bottom step of a flight of stairs and below a top step of a flight stairs so that information on the sign is visible to people moving both up and down the flight of stairs.




According to the present invention there may also be provided a sign that includes a display panel for displaying information, and a pair of side walls, each of the side walls being connected to a side edge of the display panel and increasing in width from a top of the display panel to a bottom of the display panel. The sign may include a hook member connected to the walls and configured to be placed about a support. The side walls and the display panel may be configured to form a cavity to permit nesting of another sign within the cavity. The side walls may be substantially parallel and extend at a substantially right angle relative to the display panel.




The present invention includes a sign for hanging on a door handle so that a person approaching the door from a direction parallel to the plane of the door is alerted to the presence of the sign. The door handle sign includes a display panel for displaying information, and a pair of side walls. Each of the side walls is connected to a side edge of the display panel and has an increasing width from the top of the display panel to the bottom of the display panel. The sign also includes a hook connected to the walls and configured to be placed about the door handle. The side walls may be of sufficient width adjacent the bottom of the display panel and may be positioned to project away from the door so that at least one of the side walls is visible when approaching the door. The door handle sign may also include a cavity to permit nesting of similar signs.




The present invention also includes a method of alerting a person approaching a door to the presence of a sign on the door handle. The method includes providing a sign having a display panel for displaying information, and a pair of side walls, each of the side walls being connected to a side edge of the display panel and increasing in width from a top of the display panel to a bottom of the display panel. The method includes placing the sign about the door handle so that one of the side walls projects away from the door and is visible when approaching the door.




It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

DETAILED DESCRIPTION




Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. These embodiments are intended to be purely exemplary of the invention.




The present invention provides a hanging sign that can display a message near an area to be emphasized, such as a hazardous area requiring pedestrian attention. The sign may be positioned in a variety of locations. For example, the sign may be located directly above a wet stair, on a hand rail assembly along a walk way, on a door handle to indicate a potential hazard beyond the door, on an out of service elevator, or in an area in need of a directional marker.





FIGS. 1 and 2

generally show a hanging sign


100


according to the present invention. The sign


100


is suspended from a support above a walking surface so that the sign does not pose a trip hazard. The sign


10


may be hung, for example, from a handrail assembly


500


and, in particular, from a bracket


540


mounted on a wall


700


to hold a handrail


550


. A handrail is often installed adjacent stairs


600


. In some instances, however, handrails may be provided adjacent ramps or horizontal passageways.




A first embodiment of a hanging sign


100


according to the present invention is disclosed in detail in

FIGS. 3-7

. The hanging sign


100


includes a pair of side walls


120


,


130


(see

FIG. 4

) having first and second surfaces for displaying messages. In this embodiment, the side walls


120


,


130


are connected to one another to form an inverted v-shaped cross-section, as shown in FIG.


6


. The first and second surfaces face in generally opposing directions. For example, the side walls


120


,


130


may be angled such that pedestrians walking up and down the stairs


600


(

FIG. 1

) are able to view at least one of the first and second message surfaces. Preferably, the first and second surfaces are positioned at an angle of between thirty-five and forty-five degrees with the vertical plane passing through the line A—A shown in FIG.


4


. It is within the scope of the invention, however, to dispose the first and second surfaces in respective orientations that are appropriate for the circumstances encountered at the location where the sign is to be deployed.




The sign


100


also includes a hook member


140


that may be placed about a structural support, such as bracket


540


, to suspend the sign. The hook member


140


may include a generally circular opening


160


, as shown in FIG.


4


. The generally circular shape allows the hook member


140


to be placed around a variety of structural supports, such as a portion of a railing assembly or a door knob. As an alternative to hanging from the hook member


140


, the sign


100


may include, for example, a magnet for retaining the wall against a metal surface or slots or openings for fastening the sign directly to a wall or support. The magnet may be used, for example, to position the sign on an elevator in order to communicate an “out of service” condition to a user.




The sign


100


may include a base wall


150


connected to the side walls


120


,


130


. The base wall


150


provides increased structural stability. Also, the base wall


150


provides a smooth contoured finish that minimizes the possibility of a pedestrian or object passing along the handrail assembly from being caught or snagged on the sign. The base wall


150


may be omitted, however, if desired to reduce the weight of the sign


100


or the amount of manufacturing material required.




A transition panel


180


can be provided to connect the hook member


140


to the side walls


120


,


130


. In

FIG. 4

, the transition panel


180


extends from the side walls


120


,


130


and gently slopes toward the hook member


140


. The transition panel


180


provides a transition from the three-dimensional message carrying portion of the sign to the hook member


140


. The transition panel


180


also can provide another surface for displaying messages.




The sign


100


preferably forms a cavity


170


, as shown in the cross-sectional view of FIG.


5


. The cavity


170


allows multiple signs to be nested or stacked together. This allows for efficient shipping and handling of a large number of signs. The depth of the cavity


170


and overall size of the sign may be varied as required.




The sign


100


having a cavity


170


is preferably injection molded from high density polypropylene. However, many other plastics well known to those of ordinary skill in the art may be suitable for making the sign from a molded or vacuum forming process. In addition, the sign


100


may be stamped or formed from a thin roll of metal such as steel or aluminum.




While certain advantages are associated with providing a sign having the cavity


170


, it is within the scope of the invention to provide a back wall


190


(

FIG. 7

) to provide a lightweight, hollow structure. Furthermore, in some situations it may be desirable to form an essentially solid sign. In this case, the walls and interior of the sign all can be made of, for example, a lightweight, cushion type material such as foam rubber.




A second embodiment of the present invention is shown in

FIGS. 8-10

. The sign


200


of this second embodiment primarily differs from the first embodiment in the structure of the hook member


240


, transition panel


280


, and base wall


210


. These features may be incorporated individually or collectively into the sign


100


of the first embodiment. Also, the various modifications of the first embodiment discussed above can be applied individually or collectively to the second embodiment.




In the sign


200


of the second embodiment, the hook member


240


includes a recessed portion


244


sized to fit commonly used handrail brackets, as shown in FIG.


9


. For example, the diameter of the semi-circular recessed portion


244


is preferably approximately 1.2 inches. The hook member


240


may further include flat surfaces


242


located adjacent to the recessed portion


244


. The flat surfaces


242


may be included to facilitate hanging the sign on a conventional janitorial cart such as, for example, the 6173 Janitor Cart manufactured by Rubbermaid Commercial Products LLC.




The transition panel


280


of the sign


200


includes a portion that extends between the side walls


220


,


230


, which can provide a surface for displaying cautionary messages, trade names, or the like. The transition panel


280


can minimize the protrusion of the sign away from, for example, a wall when positioned to hang from a handrail assembly. Compare

FIG. 5

(first embodiment) with

FIG. 10

(second embodiment). Preferably the depth of the sign


200


, i.e. the distance D shown in

FIG. 10

, is approximately 2.5 inches so that when the sign


200


is suspended from a conventional handrail bracket it does not protrude into the passageway or stairway being transited. The depth and overall size of the sign may be varied to suit the particular purpose.




The base wall


210


of the sign


200


preferably is rounded. As shown in

FIGS. 8 and 9

, the base wall may take the shape of a half section of a truncated cone. In addition to the advantages of a base wall mentioned in connection with the first embodiment, the rounded appearance of the base wall


210


in the second embodiment increases the visibility of the sign.




The present invention offers several practical advantages. For example, as shown in

FIG. 2

, the narrow shape of the hook member


140


allows for a pedestrian's hand to grasp the rail


550


without interference from the sign


100


. As a further example, the distance E that the sign


100


projects away from the wall


700


is less than the distance F that the handrail


550


extends into the passageway, thereby minimizing the likelihood of the sign


100


interfering with passing pedestrians. The preferred dimensions of the sign


100


are 17 inches in length by 6.25 inches wide by 2.5 inches deep to ensure that the above mentioned advantages are provided. The width of the hook member


140


is preferably ⅜ inch in order to avoid interference with the pedestrian's hand.




A third embodiment of the present invention is shown in

FIGS. 11-14

. The primary difference between the sign


300


of this third embodiment from the sign of the first embodiment is omission of the hook member


140


and the inclusion of a tab member


360


. The tab member


360


may be incorporated into the sign


100


of the first embodiment. Also, the various modifications of the first and second embodiments discussed above may be applied individually or collectively to the third embodiment.




In the sign


300


of the third embodiment, the transition panel


380


is connected to a tab member


360


. The tab member


360


may include an opening


365


sized to fit commonly used fasteners. The sign


300


may be secured to a support structure by passing a screw or other similar fastener through the opening


365


and securing the fastener to the support structure.




As an acceptable alternative, the opening


365


may be omitted and a magnet


362


may be provided. As shown in

FIG. 13

, the magnet may be positioned on the bottom of the tab member


360


in order to avoid interference with cavity


370


formed by the side walls


320


,


330


and the base wall


350


. Alternatively, the magnet


362


may be positioned in any appropriate location that avoids interference with the cavity and the ability of multiple signs to be nested together. As shown in

FIG. 14

, the sign may include a solid back wall


390


and the magnet


362


may be mounted to the back wall. A fourth embodiment of the present invention is shown in

FIGS. 15-18

. As shown in

FIG. 18

, a hanging sign


400


may be suspended or hung from a handle


810


of a door


820


.




The sign


400


has a display panel


410


that is angled away from the door


820


and toward the viewer to make it easier to receive the message. In addition, the three-dimensional shape of the sign


400


serves to alert pedestrians to the presence of the sign well before they arrive at the door.




The sign


400


includes a pair of side walls


420


,


430


. The side walls


420


,


430


may be angled so that the width of each of the walls increases from the top to the bottom of the display panel


410


. The shape of the side walls


420


,


430


provides at least two advantages. First, the side walls tilt the display panel


410


away from the surface of the door


830


and toward the viewer thereby making the sign easier to read. Second, the side walls


420


,


430


extend away from the door a sufficient distance so that the walls may be easily seen by pedestrians approaching the door from the side, thereby alerting the pedestrians to the presence of the sign and providing a heightened awareness of potentially dangerous conditions indicated on the display panel. It is within the scope of the invention to modify the angle and shape of the side walls in order to create the appropriate sign shape for the circumstances encountered at the location where the sign is to be deployed.




As shown in

FIGS. 15 and 16

, the display panel


410


is preferably a flat surface because it facilitates the display of messages. It is within the scope of the present invention, however, to provide a rounded or patterned surface for the display panel


310


as dictated by circumstances encountered in the area of use.




The sign


400


includes a hook member


440


that may be placed about a structural support to suspend the sign


400


. The hook member


440


may surround a generally circular opening


450


. The specific shape of the opening may be varied to suit the particular support being used. For example, the hook member


440


may be modified to include the recessed portion


244


and/or the flat portion


242


shown in FIG.


9


. In addition to the door handle


810


shown in

FIG. 18

, the hook member


440


of the sign


400


may accommodate a wide range of bracket hardware. For example, the hook may be used on indoor or outdoor stair case railings. Alternatively, the sign


400


may include, for example, a magnet for retaining the wall against a metal surface or slots or openings for fastening the sign directly to a wall or support. As described above with regard to the other embodiments of the invention, the magnet may be used, for example, to position the sign on an elevator in order to communicate an “out of service” condition to a user.




The sign


400


, may further include a base wall


460


. The base wall


460


connects the side walls


420


,


430


together and preferably is rounded, as shown in FIG.


15


. The base wall


460


provides increased structural stability and the advantages associated with a smooth contoured finish.




The sign


400


preferably forms a cavity


470


, as shown in the cross-sectional view of

FIG. 17

, to permit nesting or stacking and other advantages related shipping and handling of a large number of signs. While certain advantages are associated with having a cavity backed sign


400


, it is within the scope of the invention to provide a solid back wall in order to provide a totally encased hollow enclosure. The solid back wall may take the form shown in

FIG. 7

, for example. Furthermore, as described above, in some situations it may be desirable to use a cushion type material such as foam rubber for the entire sign. In these cases, the sign


400


would have a solid interior.
