"Device for displaying characters"

The invention relates to a device for the display of characters that appear successively on an information carrier are arranged and optionally brought behind a viewing window, with several display units can serve as a display board in side-by-side and / or one below the other.

Such devices are known (DT-OS 2 139 86I). With them, a roller is provided as an information carrier and the characters, in particular digits, are located on the circumference of the roller, which is arranged immediately behind the viewing window, so that when the roller is rotated in each case another number is brought behind the viewing window.

In this device, the height of the digits is small in relation to the height of the case, because each 10 digits must be arranged on the circumference of the roller, because of the requirement of good legibility a accordingly large diameter is required, which means that the housing height is correspondingly large, there are several these devices are arranged in lines and several lines on top of each other, then the already

relatively small digits through disproportionate large distances separated from each other and it is difficult to grasp a group of displayed digits at the same time; in addition, this leads to prohibitively large panel dimensions.

The object of the invention is to increase the height of the digits without changing the height of the case, and in particular to achieve the largest possible number of digits with the smallest possible line spacing.

This object is achieved by an indexing mechanism acting on a wheel, the wheel having external teeth for an internally toothed belt that is attached in the area of the viewing window via two pulleys and on the outside of which the characters are arranged.

The fact that the tape serving as an information carrier has a greater circumferential length than the wheel larger, in particular higher digits are arranged on the tape, which are also displayed in full because the tape makes better use of the area available for the viewing window Housing allows. There is also the advantage that the tape over the pulleys behind the viewing window in is guided on a plane, so that the characters can be read better because of the lack of curvature.

In order to fully utilize the area available for the viewing window, an arrangement is recommended in which the axial dimension of the shafts of the pulleys corresponds at least to the clear width of the viewing window.

Appropriately, the tape is a plastic or rubber tape printed on its outside with the characters " Has sufficient elasticity and placed on the wheel and the pulleys with a certain preload can be.

Although basically the invention is an excellent way to operate the display units of the From the front, the height of the digits, the viewing window and thus the perceptibility of the characters can be improved ■■% are when the for the operation of the stepping mechanism provided pushbuttons from the side opposite the "viewing window" of a device receiving the device Housing are accessible. In this case, almost the entire front of the housing can be used as a viewing window be used. In the case of devices arranged in rows one above the other, the distance between the devices in different Lines located characters reduced to a minimum.

It can also be advantageous if the same series of characters are offset from one another, if necessary are arranged in reverse order, with the characters of one series appearing on the viewing window and the characters of the other series on one on another side, especially the back, of the case arranged control windows appear. This results in the possibility of the one that appears on the viewing window Control display from another side, especially the rear of the device. Viewing window and control windows can be designed in such a way that they only display the series of characters of interest can be recognized, while the series of characters intended for the other window remains covered.

The invention is described below with reference to one in the drawing illustrated embodiment explained. Show it:

1 shows a longitudinal section through a device for displaying characters, which can preferably be used for display panels;

FIG. 2 shows a section in the direction II - II through the object according to FIG. 1;

3 shows a section in the direction III - III through the object according to FIG. 1; and

_{3 and} 4 a view in the direction of arrow IV of the object according to FIG. 2.

Since display boards, in particular course display boards, are known per se, their description can be found below can be omitted, rather the description and illustration of the display unit for one in each case Concentrated letters or numbers.

The device used as a display unit has a housing 2 that can be closed with a cover 1. In the housing 2 there is a mandrel 3, which serves as a shaft for a wheel 4 which has an external toothing 5, in which engages an internal toothing 6 of a rubber band 7 *, The rubber band 7 is printed on its outside with numbers and is guided past the front 9 of the housing 2 in a viewing window 8. There are also behind the viewing window 8 two pulleys 10, 11, the center distance of which is at least the clear width of the viewing window 8 corresponds. By gradually turning the wheel 4 with the help of a stepping mechanism you can the digits are brought behind the viewing window 8.

The housing 2 is essentially prismatic and has protruding cams on its side surfaces "or recesses 13, so that similar housings can be coupled to each other by locking the cams 12 into the recesses 13, so that in easier Way display rows for panels can be formed.

The housing 2 also has on its front 9 openings 14, 15 for pushbutton buttons 16, 17 of a step switch mechanism on. The button buttons 16, 17 are integrally formed with a button 18 and resilient with this button Sections 19, 20 connected. On the button 18 there is a recess 21, which is one on the back 22 of the Housing 2 arranged recess 23 is opposite and a coil spring 24 receives the one in the recess 21 molded pin 25 is held. The resilient sections 19, 20 of the button 18 are with a part 26 connected, the arcuate stop or sliding surfaces 27, 28, which in the middle part of the Housing 2 arranged housing-fixed stop pins 29, 30 are assigned. Furthermore, there are 26 transport pins on the part 31, 32 arranged, each of which is provided with an inclined stop surface 33, 34. The stop surfaces 33, 34 cooperate with teeth 35 of a toothed ring 36 molded onto the wheel 4.

The one in the area of the mandrel 3 or the hub 37 of the wheel Part 26 of the button 18 provided with a recess 38 also has the transport pin with respect to the hub 37 31, 32 opposite a transport wedge 39, the shape of which is one between two teeth 35 formed gap is adapted. A further recess 40 adjoins the transport wedge 39; in the one housing-fixed fixing pin 41 engages.

7531998 2l05.76

In the rest position, the button 18 lies symmetrically in the housing and the transport wedge 39 is held by the helical spring pressed against the ring gear 36 and "causes a fixed angular position of the wheel 4 and thus a fixation of the the number appearing on the viewing window 8,

When Z ₀ B _{0 of} the pushbutton 16 is pressed, pressure acts on the helical spring 24, which is offset in relation to the direction of pressure.

The resilient section 19 enables the pivoting of the Button 18. Then the button slides with the sliding surface 27 on the stop pin 29 and with the edges of the tapers formed recess 40 on the fixing pin 41 in the direction of the rear side 22 of the housing 2, there the transport wedge 39 releases the ring gear 36 and the transport pin 31 engages with its stop surface 33 on a tooth 35 and rotates the wheel 4 by half a tooth pitch. When the push button is now released is, the coil spring 24 pushes the button 18 back into its starting position, the transport wedge 39, which is now to the side of a tooth 35, engages in a tooth gap and rotates the wheel 4 in

w same meaning further until the corresponding switch position is reached and the next number appears on the viewing window 8.
