Definitions
- the invention relates to a rolling sign of the kind pre ⁇ sented in the preamble of claim 1.
- Such rolling signs are known in many different versions, such as purely manual signs, where the rolls are operated and the sign adjusted by means of a handle, or where the rolls are engine-driven, for example by electromotors.
- the purely mechanical sign has the great disadvantage that a person is required to adjust the sign every time a change has to be made, which therefore requires access to the ad ⁇ justment device of the sign.
- the known engine-driven rol ⁇ ling signs have the great disadvantage that the driving engines and the driving connections from the engines to the rolls require space in the sign, which often results in an unacceptable volume.
- the device according to the invention By designing the device according to the invention as pre- sented and characterized in claim 3, further space is saved, since the driving engine too is mounted inside one of the rolls.
- One driving engine in one of the rolls is sufficient, since the energy stored in the springs ensures rapid and uniform change of signs.
- the spring mounted in each roll thus has two functions. Firstly, it contributes towards ensuring constant tightness of the sign face, and secondly it contributes towards establishing the operation of the sign in both directions, since during rotation of the rolls, a continuous exchange of energy is taking place between the electromotor and the two springs via the sign face, so that uniform operation of the sign face is achiev ⁇ ed all the way from the one end hereof to the other end.
- the motor is coupled to the rolls by a gear system as presented and characterized in claim 4.
- the space requirements are further reduced, since the gear de ⁇ vice too is mounted inside one of the rolls, namely in the roll, in which the driving engine is mounted.
- the whole driving device is thus mounted inside the rolls which support the sign face, and the driving device with the electromotor is preferably mounted as presented and char ⁇ acterized in claim 6.
- the invention also relates to a rolling sign of the kind presented and characterized in claim 8.
- a rolling sign is hereby achieved, which requires absolute minimum space, and where driving connections and driving devices are well- protected inside the rolls, both against dirt, dust, humid ⁇ ity and against any outside mechanical influence.
- the rolling sign according to the invention By additionally designing the rolling sign according to the invention as presented and characterized in claim 9, the possibility is provided of producing a sign built of modules with signs and symbols, for example letters and/or figures, so that any text may be shown on the sign by suit ⁇ able electrical control of the individual roll units.
- a sign is hereby produced, which can be operated from a distance in a simple manner and which can also display any desired text or line of figures.
- fig. 1 shows the principle of the device for a rolling sign according to the invention
- fig. 2 shows an axial section of the driving roll in fig. 1
- fig. 3 shows an axial section of the driven roll in fig. 1.
- Fig. 1 of the drawing shows the device for a rolling sign 1 according to the invention and comprising a driving roll 2 with a built-in electromotor, and a driven roll 3.
- a driving roll 2 with a built-in electromotor and a driven roll 3.
- a driven roll 3 of the draw- ing The internal structure of both rolls will be explained in more detail later with reference to figs. 2 and 3 of the draw- ing.
- a sign face 4 is. secured to the rolls 2 and 3, and the in ⁇ formation to be displayed is shown in appropriate positions of display on the sign face.
- fig. 1 of the drawing only shows four letters, A, B, C and D, in one position of display. It is obvious to anybody that on a sign face 4 of a suitable length, for example of several metres, the possibility is- provided of displaying informa ⁇ tion about for. example the stops of ⁇ a-public..transports—on. any other desired information.
- the sign face 4 is transparent with printed, coloured text 5. Behind the sign face is mounted a light source 8 with a re ⁇ flector 6, so that only that part of the sign face, which is to be displayed, is illuminated from behind.
- Each of the rolls 2 and 3 is provided with a number of longitudinally extending slots 7 having a dovetailed cross section. In the shown example, there are three slots in each roll.
- the sign face 4 is secured to the rolls by means of one of the slots in each roll, namely the slot 7'.
- the sign face is fastened by being led down into the slot which is hereafter filled up with a strip of a suitable material.
- the rolling sign should naturally be built into either a suitable cabinet, or possibly directly into for example the means of transport, in which it is applied, for example into the front of a vehicle or possibly directly above the entrance.
- Fig. 2 of the drawing shows a central, axial cross section of the roll 2
- fig. 3 shows a corresponding section of the roll 3, in that the roll 2 is a driving roll with a built-in electromotor, whereas the roll 3 is a driven roll without a motor.
- Fig. 2 sketchily shows the roll 2 mounted between two hol ⁇ ders or side walls 12 having suitable recesses for the roll to rotate freely.
- the section is made so that it passes down through a slot 7, and the drawing moreover shows that the roll is a cylinder 11 with a small wall thickness.
- the cylinder 11 is preferably made of aluminium by extrusion and is hereafter cut off in suitable lengths.
- a housing 24 comprising ' flanges 23 for engagement with the slots 7, so that the housing 24 rotates simultaneously with the cylinder 11.
- the gear device with the spiral 38 is self-locking; consequently, further locking means for retaining the cylinder 11 in a certain position are unnecessary.
- the motor 13 and the retainer 14 are secured to the cabinet of the sign or to another fixed re- taining member by means of retaining members 21.
- a torsion spring 27 around a spring retainer or cylinder 28, in that the spring 27 is at both ends secured to a spring retainer 26, 39.
- the spring cylinder 28 is in the middle of fig. 2 terminated by a retainer 25 which by a suspension 22 is secured to the housing 24.
- the spring retainer 26 is rotated through the gear which is explained below for exchange of energy by tightening or slackening of the torsion spring.
- the spring retainer 26 at the one end of the spring is rotatable and is by a toothed gear, for example a planetary gear 30, 31, 32, 33, 34, coupled to a retainer 36, 37 which is secured on the cabinet or the like of the sign.
- the gear 30-34 gears down from 1:2 to 1:15, preferably 1:10, between the numbers of revolution of the cylinder and of the spring at the retainer 26, the result being that when the motor 13 rotates the cylinder, the spring 27 will be tightened by one revolution each time the cylinder has made ten rota ⁇ tions, if the gear ratio is 1:10.
- Fig. 3 shows a driven roll which except for a pipe section 41 and a retainer 42 which take the place of the motor construction and the gear housing herefor, is identical with fig. 2. All corresponding parts thus have the same re- ference numbers.
- the gear 30-34 prefer ⁇ ably has the same gear ratio as in cylinder number 2.
- the driving engine 13 is preferably a motor which is con ⁇ trollable and by which the direction of revolution is easily turned.
- the sign is controlled by switching the power to the engine on and off, and this is for example controlled by suitable perforations or indications (not shown) in the edge of the sign face 4, and read by a photo ⁇ cell arrangement or the like.
- the edge indications may be designed in such a manner that all the time the photocell arrangement and the control circuit belonging to it senses, which part of th ⁇ ign is within the field of vision at the moment, so that the speed of the motor can be adapted to the distance the sign has to move, when it is to be re ⁇ arranged to another desired position.
