Description

SIGNAGE

TECHNICAL FIELD

Embodiments of the invention relate to signage, and in particular, signage as used for indicating a direction.

BACKGROUND

Figure 1 illustrates a direction sign 10 as known in the prior art. The direction sign comprises a place indicator 12 which is here “Food Court” and a direction indicator in the form of an arrow 14.

In use, the sign 10 is attached to a post, a wall or suspended from the ceiling so that it is visible to people seeking direction assistance. In this orientation, the arrow can have at least two meanings. In a first meaning, the arrow is intended to indicate that the place indicated (in this instance, the food court) is behind the sign so that the informée should walk towards the sign and carry on in that direction. However, the same sign may also be used in the vicinity of stairs, an elevator or an escalator to indicate that the informée should proceed up to reach the indicated place.

Since this sign is place and context dependent it can be inherently confusing, particularly where it is possible to continue on or to go up.

Embodiments of thé current invention reduce this confusion therefore reducing the effort required to reach a desired location and thereby providing more efficient direction signage.

SUMMARY A first embodiment of the invention extends to direction signage comprising an indicator for indicating a direction and a representation of depth wherein the indicator is orientated relative to the representation of depth so that the direction indicated by the indicator comprises a direction of forwards.

The representation of depth may comprise at least one quadrilateral shape and at least one obliquely orientated line.

The representation of depth may comprise more than one obliquely orientated line.

The representation of depth may comprise four obliquely orientated lines.

The at least one obliquely orientated line may be located adjacent a corner of the quadrilateral shape.

The representation of depth may comprise two quadrilateral shapes wherein said oblique line may be orientated between corresponding corners of the two quadrilateral shapes.

The representation of depth may comprise a first quadrilateral shape located within a second quadrilateral shape, the representation of depth may further comprise at least two oblique lines, wherein each oblique line connects a corner of the first quadrilateral shape to a corresponding corner of the second quadrilateral shape.

The direction signage may comprise four oblique lines connecting corners of the first quadrilateral shape to corresponding corners of the second quadrilateral shape.

One or more of the oblique lines may be orientated between 30 and 60 degrees to a vertical, or between 110 and 150 degrees to the vertical.

The quadrilateral shape, or each quadrilateral shape, may be a rectangle or a square.

The direction signage may comprise at least two indicators of direction, wherein each indicator is orientated between 30 and 60 degrees to a vertical, or between 110 and 150 degrees to the vertical.

The direction signage may comprise four indicators of direction, wherein each indicator is orientated between 30 and 60 degrees to a vertical, or between 110 and 150 degrees to the vertical.

The orientation of any one, or more, of the indicators of direction may be: between 30 and 60 degrees to the vertical; between 110 and 150 degrees to the vertical; between 40 and 50 degrees to the vertical; between 130 and 140 degrees to the vertical; 45 degrees to the vertical; or 135 degrees to the vertical.

The indicators of direction may comprise arrows pointing towards a central region.

The indicators of direction may comprise said representation of depth.

The direction signage may comprise a substrate and printing or markings applied to the substrate, wherein said indicators of direction and said representation of depth are comprised of said printing or markings.

The substrate may define a two dimensional surface and said printing or markings may be applied to said two dimensional surface.

DESCRIPTION OF ACCOMPANYING FIGURES

Embodiments of the invention are described with reference to the accompanying schematic diagrams where:

Figure 1 illustrates a direction sign according to the prior art; and

Figures 2 to 5 illustrate direction signage according to embodiments of the invention.

DESCRIPTION OF EMBODIMENTS

Figure 2 illustrates direction signage 20 comprising a substrate 22 on which various markings 24 have been adhered. It is to be realised that all of the embodiments of direction signage described herein comprise markings adhered to a substrate. The manner in which such direction signage is made is known in the art and will not be further discussed.

In the direction signage 20, the markings 24 comprise four arrows: 26, 28, 30 and 32. Dashed line 42 indicates the vertical direction when the direction signage is in use. The arrow 26 is orientated at an angle 34 to the vertical. Similarly, arrow 28 is orientated at an angle 36 to the vertical; arrow 30 is orientated at an angle 38 to the vertical; and arrow 32 is orientated at an angle 40 to the vertical. Angles 34 and 36 are 45°, angle 34 being measured in a counter-clockwise direction, and angle 36 being measured in a clockwise direction. Angles 38 and 40 are 135° angle 38 being measured in a counterclockwise direction, and angle 40 being measured in a clockwise direction. In further embodiments

Each of the arrows 26, 28, 30 and 32 point towards a blank central region 46 on the direction signage 20. In this embodiment, the orientation of the arrows 26, 28, 30 and 32 relative to the border 44 of the direction signage 20 makes it clear that the direction indicated is forwards. The oblique orientation of the arrows 26, 28, 30 and 32 creates a form of perspective in the direction signage 20 thereby making it clear that the informée is to proceed forwards. Since the informée is facing the direction signage 20, the forwards direction will indicate a direction behind the direction signage 20.

Therefore, the arrows 26, 28, 30 and 32 create a representation of depth by adding a perspective to the flat, two-dimensional direction signage 20. ' . Figure 3 illustrates a direction signage 50 according to a further êmbodiment of the invention. The direction signage 50 is similar to the direction signage 20 of Figure 2 and similar features are denoted with similar reference numerals. The direction signage 50 comprises four arrows: 54, 56, 58 and 60 which are orientated in the same angle and direction as corresponding arrows 26, 28, 30 and 32 of Figure 2. However, the arrows 54, 56, 58 and 60 differ from the arrows 26, 28, 30 and 32 of Figure 2 in that they are shorter.

The direction signage 50 further comprises a box 52 located at the centre of the direction signage 50. The arrows 54, 56, 58 and 60 lie on imaginary lines joining the corners of the border 44 of the direction signage 50 and corresponding corners of the box 52.

In this embodiment therefore, the box 52 acts as the place indicator instead of the central region 46 of the direction signage 20 of Figure 2. However, the arrows 54, 56, 58 and 60 serve to indicate direction and represent depth, as for the direction signage 20 of Figure 2.

Figure 4 illustrates a direction signage 70 according to a further embodiment of the invention. The direction signage 70 is similar to the direction signage 20 of Figure 2 and similar features are denoted with similar reference numerals.

The direction signage 70 comprises four oblique lines 72, 74, 76 and 78 and a box 80. The box 80 is located at a central region of the direction signage 70. The direction signage 70 further comprises an arrow 82 which is located between oblique line 78 and oblique line 76, and is located outside of box 80.

In this embodiment, the box 80, together with the oblique lines 72, 74, 76 and 78 form a representation of depth since they together create the impression of a corridor. The arrow 82 acts as an indicator indicating the direction. Since an informée viewing the direction signage 70 will be generally orientated so that they are facing the direction signage 70, the arrow 82 will indicate a direction of forwards (i.e. behind the direction signage 70).

Figure 5 illustrates a direction signage 90 according to a further embodiment of the invention. The direction signage 90 comprises two oblique lines 92 and 94 and a box 96. The box 96 is located at a central region of the direction signage 90. The direction signage 90 further comprises an arrow 98 which overlaps a bottom edge of the box 90.

In this embodiment, the box 96, together with the oblique lines 92 and 94 form a representation of depth since they together create the impression of a corridor. The arrow 98 acts as an indicator indicating the direction. Since an informée viewing the direction signage 90 will be generally orientated so that they are facing the direction signage 90, the arrow 98 will indicate a direction of forwards (i.e. behind the direction signage 70),

In the embodiments of Figures 1 to 4, the oblique lines or arrows link the corners of the respective signage, either directly or indirectly. However, it is to be realised that a quadrilateral shape may take the place of the outer border 44 of the signage of the Figures, This would allow the signage to be printed (or otherwise adhered) to other shapes and to incorporate further information such as a destination name or type.

In a further embodiment, the destination is indicated in the box, or in the central region.
