Definitions
- the present invention relates to a display device with rearrangeable characters, such as a price display at sales points, or other displays, where a quick and simple change of the characters is desirable, so that a change of the display may be readily performed without the need for any loose signs, writing utensils or the like.
- Displays of this type are e.g. known from US-A-3740878, in which the individual character is created by means of a number of small squares in contrasting co- lours. The squares pivot on vertical shafts and form together a rectangular surface.
- the displaying of characters is effected by rotating squares of identical contrasting colour into horizontal and vertical directions in the rectangle so as to form edged characters, preferably figures.
- the front plate of the display with the.rec- tangles and the rotatable squares may after adjustment into the desired signs be locked to a rear plate so as to prevent further rotation of the squares.
- the display device according to US-A-3740878 is not suitable for displaying digital characters, and it is not particularly suitable for indoor price displaying, where the price displays should be relatively small and easy to read.
- the rod When an element is to be activated so as to form part of a figure, the rod is rotated manually about its longitudinal axis so that the side of the element with the contrasting colour appears, and in this way each invididual element is activated so as to form a combination of elements showing the desired figure.
- a deletion of the figure is effected by displaying the side of the element having the same colour as the substrate.
- the object of the present invention to provide a manually operated display with changeable digital characters and to eliminate the drawbacks dealt with in connection with the above the prior art.
- the particular feature of the present invention is a display with easily changeable, self-locking, easily readable digital characters, which display is inexpensive and relatively small and therefore particularly suitable for indoor use, e.g. in retail shops.
- Fig. 1 is a front view of a display according to the invention, ready to use;
- Fig. 2 shows the front plate of the display, where the character elements have been removed
- Fig. 3 shows a character element consisting of two complementary elements
- Fig. 4 shows the rear or locking plate of the display
- Fig. 5 is an enlarged, longitudinal and sectional view through a mounted element in its resting position in the front plate;
- Fig. 6 is also an enlarged and longitudical view through a mounted element, which has been rotated into a position perpendicular to the front plate.
- a price display device comprising three 7-segment digital figures and a point has been employed.
- the reference numeral 1 designates the front plate of the display, and which is made of a material suitable for displays, e.g. nylon with glass.
- the reference numeral 2 designates an individual element, and 3 designates a point.
- the elements have on their first flat side the same colour as the front plate, and on their second, flat side they have a contrasting colour, so that the individual element in its resting position in the front plate either forms an integrated part of or is clearly distinct from the front plate as far as the colour is concerned.
- the front plate 1 has recesses 7 which for each figure portion in the plate leaves center areas 6 and rods 4,5, which connect the centre area with the remaining part of the front plate 1 or with the adjacent center area 6.
- the shape of the reces- ses 7 corresponds to that of the elements 2 in their mounted posi ⁇ tion, which will appear from a comparison between Figs. 1 and 2.
- the crosssectional shape of the rods 4,5 is close to elliptical, vide Figs. 5 and 6, which will be explained in greater detail below.
- Fig. 3 shows an individual element consisting of two complementary members 12,12' of a plastics material, e.g. impact-proof styrene or ABS.
- Each member has at one end a hole 15 for a projection 16' on the complementary member and correspondingly a projection 16 at the other end, which projection 16 fits into a hole 15' in the comple- mentary member.
- Both members are provided with a transversal groove 13, and the members form together, when the element is mounted in the plate 1, a bearing for the rod 4.
- the rod 4 becomes a transversal shaft, on which the element may be rotated.
- each element has internal protrusions 14,14', 17,17' at its ends, which protrusions in pairs of two abut against each other, when the element is mounted.
- the assembly of two members to each other into an element in its assembled position around the transversal shaft 4 is preferably carried out by means of ultrasonic welding, as other mounting methods, such as interference fit, may be employed depen- dent on the size of the element.
- the end shapes of the assembled element 2 are such that the end of an element without any gap abuts on the corresponding end of an adjacent element when the elements are embedded in the plate 1 so as to form the desired character. This will be obvious from Fig. 1.
- any further rotation of ti elements may be preven ⁇ ted by means of a rear or locking plate 8 of the same material as the plate, cf. Fig. 4, which rear or locking plate 8 by means of a flange 10 and a locking hook 9 may be fixed onto the plate 1.
- weight reducing recesses 11 are formed so that the remaining plate portions 8,8',8" prevent inadvertent rotation of the elements 2, when the rear plate 8 is arranged on the front plate 1.
- the individual element 2 is self-locking in the embedded position (resting position) in the plate 1 with the element assembled around its rotating shaft 4.
- the self-locking has been obtained in the following manner:
- the shaft 4, which is cast or punched integrally with the plate 1, has a circular crosssection and is bevelled in such a way that the shaft has flat sides forming surfaces, which are parallel with the front and rear sides of the plate 1.
- the crosssection of the shaft thereby becomes almost elliptical, and the great axis is parallel to the plane of the plate 1, while the small axis is perpendicular to the plate.
- Each member 12,12' has an inner recess, the lower surfaces 19,19' of which in the assembled (welded) element 2 in its embedded position in the plate 1 abut firmly against the bevelled surfaces of the shaft 4.
- the recess surfaces 19,19' may be provided with grooves 13 (see Fig. 3) in the transversal direction of the element. The grooves 13 are not shown in Figs. 5 and 6. If the rod is rotated manually out of its embedded position into a position perpendicular to the plate 1, see Fig.
- the lower surfaces 19,19' will slide along and onto the curved surfaces of the shaft 4, and at the same time the inner gap formed by the recesses between the members 12,12' is slightly expanded, which the resiliency of the material allows, and a spring tension exerted on the shaft 4 is generated in the two members 12,12'. If the rotation of the element 2 is continued until it reaches its embedded position in the plate again the spring tension will urge the surfaces 19,19' in the members into firm abutment with the bevelled surfaces of the shaft 4 with a small click. As will readily appear from Figs. 5 and 6 the manual rotation of an element into the desired character on the plate 1 may take place in both directions about the shaft 4.
