Definitions

  • the invention relates to a display module for a display panel with a block housing, on the front of which a display window is provided, through which a symbol, for. B. a number, a letter or the like., Can be displayed, a gradually adjustable inside the housing arranged symbol carrier for the symbols to be displayed and an externally operable adjustment mechanism for the symbol carrier.
  • display boards for stock prices or the like must have a large number of display modules one above the other and next to one another, that is to say arranged in display lines and display columns.
  • information is available, for example names of the stock corporations concerned that remain unchanged in the long term, and on the other hand, information is required, for example share prices that change relatively frequently.
  • a display board of the type in question must meet these requirements, for which various solutions have been proposed (cf. DE-PS 27 27 406).
  • Each display module is used to display a symbol, for example a letter, a number, a mathematical function or the like.
  • Roles are known as mechanically stable carriers that can often be adjusted without damage. Roles have symbols, such as numbers, letters and the like, on their circumference. wear. These carriers can be adjusted by an externally actuated adjustment mechanism to change the symbol to be displayed. The adjustment can be done manually or from the outside by electronically, electrically or magnetically operated actuation parts.
  • a relatively large number of symbols for example 10 or more symbols
  • these symbols have a minimum diameter in order to make the symbols, in particular the letters or numbers, which are to be displayed, identifiable.
  • the numbers to be displayed have a height of only about 6 to 7 mm.
  • a known mechanical display module (DE-PS 27 27 406) has an essentially cuboid housing which is approximately 25 mm high and approximately 60 mm deep and approximately 15 mm wide.
  • the housing of this display module is made of thermoplastic and is trough-shaped with a cover covering the housing trough.
  • a viewing window is arranged on a narrow side of the housing, behind which a display tape with alphanumeric characters, in particular with the numbers 0 to 9, is passed for display.
  • deflection rollers around which the display tape is guided are arranged in the housing behind the display window.
  • a deflection pulley with a large diameter which has a transport sprocket, hereinafter referred to as transport deflection pulley
  • transport deflection pulley a transport sprocket
  • tensioning deflection pulleys arranged between the window deflection pulleys and the transport deflection pulley.
  • the display belt is closed in a ring and is transported step by step from the transport deflection roller over the transport sprocket with the aid of a stepping mechanism.
  • Switchgear include control buttons that are arranged in the housing and can be operated from above and below the viewing window.
  • the actuation buttons have engagement openings into which a ballpoint pen tip or the like can be pressed for actuation.
  • the housing of the known display unit is quite deep because of the large-diameter transport deflection roller arranged in the rear region of the housing and the tension deflection rollers necessarily present here.
  • the transport pulley is also the stepping wheel of the stepping mechanism, so that the gear ratio of the stepping mechanism is one.
  • the drive of the display tape is not yet optimally smooth.
  • the display tape which is under tension in the idle state, is further shaped, in particular when the display unit is not operated for a long time, and may stick to one of the deflection rollers. As a result, the first actuation after a long period of time may be extremely difficult or there is a risk of the display tape tearing.
  • the known display unit can only be used in connection with large covers covering the entire display panel, which is structurally complex and leads to the fact that custom-made display panels have to be produced.
  • the object of the invention is therefore to provide a display module of the type mentioned, in which the symbol carrier for the easily recognizable symbols due to their size, which can be displayed evenly in the display window, requires only little space inside the housing.
  • the easily recognizable size for. B. up to 13 mm in height
  • the symbols e.g. B. numbers, letters, mathematical function symbols and the like.
  • the symbols can also be made externally recognizable by a light source arranged behind the symbol carrier designed as an endless belt.
  • the endless tape preferably consists of plastic material, as is used in a known manner, for example in film production or in tape production. Such strip materials are tensile and do not deform at higher temperatures ren. These are preferably heat-stretched strip materials.
  • the measure of claim 2 ensures that in the idle state, ie. H. then when a certain symbol, e.g. B. a number, is displayed through the display window, the endless belt is relaxed and no forces act on the endless belt.
  • the shape stability of the endless belt is further supported by this.
  • the measure of claim 4 ensures that the endless belt is first tensioned by the slide.
  • the slide can have a tensioning part which presses on the surface of the belt when the slide is pressed into the interior of the housing and tensions the endless belt so that the perforation for the belt transport is correctly gripped by the spikes of the spike wheel. If the slide is pushed further into the interior of the housing, this second slide path causes the pinwheel to rotate and the endless belt is taken.
  • the spike can be rotated by the slide movement by a first angle of rotation corresponding to a first partial transport distance of the endless belt. This first partial transport path can correspond to approximately half of the total transport step to be carried out which the endless belt carries out during the adjustment movement.
  • the slide can be moved manually, for example with the aid of a pin inserted through an opening in the block housing, or also electrically or magnetically actuated, against the force of a spring into the interior of the housing.
  • the second partial transport step or the second partial transport path of the endless belt is carried out by the force of the relaxing spring, from which the manual or other action coming from outside via the pin is released. Due to the movement of the spring during relaxation, the spiked wheel is rotated by a further angle of rotation, through which the endless belt is conveyed further by the second partial transport distance in order to complete the entire transport step.
  • the spring can be designed as a compression spring, in particular a spiral spring.
  • an indexing device which has a switching wheel and a switching pin acted upon by the spring, with which the slide movement and the movement of the spring when relaxing on the sprocket wheel for the two partial transport paths of the endless belt be transmitted.
  • the indexing device preferably has a symmetrical switching step, so that, for example, with the aid of a second slide, as indicated in claim 12, the endless belt can be transported forward and backward by the same distance.
  • the features of claim 8 ensure a flawless transmission of the slide movement and the movement of the spring-loaded switching pin onto the pinwheel, with the division of the second gear ring provided on the switching wheel, in which the slide and the switching pin can be brought into engagement alternately, so it is dimensioned that half a division corresponds approximately to a partial transport path of the endless belt.
  • the measure of claim 9 ensures that the endless belt in its rest position, in which a certain symbol, for. B. a number through the display window is held in a locked position.
  • the endless belt is preferably only so far relaxed that at least one spike of the spiked wheel still protrudes through the perforation on the endless belt.
  • the measure of claim 10 ensures that the switching pin can be released from the locked position with the aid of the slide.
  • the configuration of the slider according to claim 11 can ensure that the slider movement for driving the spiked wheel is transmitted for the first partial transport path of the endless belt.
  • the measure of claim 13 ensures a space-saving arrangement of the endless belt inside the housing. This makes it possible for the endless belt to have a relatively large circumference, so that the symbols can be accommodated on its surface in a relatively large number in a clearly reproducible size.
  • the features of claims 14 and 15 ensure a dimensionally stable endless belt, and in conjunction with the features of claim 16 a perfect tape transport is always guaranteed without jamming of the tape, for example due to tolerances in the perforation inside the housing.
  • the block housing can be designed so that it seals the interior of the housing dust-free.
  • the block housing can have recesses and projections which engage in corresponding recesses and projections on adjacent block housings, so that the block housings can be fastened to one another in rows or in blocks to form display boards.

This corresponds to the preferred embodiment of the housing 2 made of thermoplastic material as an injection molded part. The free ends of the axes of rotation can be supported again in the cover 57. Of course, this does not mean that the rotary axes could not be constructed as separate parts in other embodiments.
  • the display module shown has the step-by-step mechanism for the step-by-step transport of the endless belt.
  • This stepping mechanism has the two actuating slides 7 arranged in the housing 2, which can be actuated from above and below the display window 3.

  • the two rear space deflection rollers 14, 15 for the display tape are arranged in the housing 2 on the narrow side opposite the display window 3 in the outermost corners of the housing 2. As a result, the full depth of the housing 2 is used for the display tape (endless tape 4).
  • the display module 1 could well be constructed in such a way that the display tape around the viewing window deflection rollers 6, 13 and the rear space deflection rollers 14, 15 is guided in a manner essentially following the narrow sides.
  • an even greater length of the display tape is made possible by the fact that the center deflection roller 16 is arranged approximately in the middle of the housing 2, preferably relative to the center of the housing 2, somewhat offset from the display window 3, and preferably that the display tape between the rear space deflection rollers 14, 15 is guided approximately U-shaped around the central deflection roller 16, so that a U-shaped free space 61 remains between the rear space deflection rollers 14, 15.
  • the center pulley 16 has a relatively small diameter when compared to the transport pulley in the prior art (DE-PS 27 27 406). This relatively small diameter allows the display tape to the rear narrow side 27 of the housing 2 to the rear area um past the center deflection roller 16 to guide castors 14, 15.
  • the free space 61 which remains between the rear space deflection rollers 14, 15 due to the skillful guidance of the display tape, can be used expediently for the stepping mechanism.
  • the step switch works in two steps. In the first step, which is triggered by pressing one of the actuation slides 7 (forward direction) or the other actuation slider 7 (backward direction), there is approximately half a transport step; when the corresponding actuation slide 7 is released, the second half of the transport step takes place by spring force. 9 to 11, the stepping mechanism has the ratchet 9 which can be brought into engagement with the driver 18 on the actuating slide 7. In addition, the spring-loaded step switch, which is in engagement with the switching wheel 9 and consists of the stop surface 32 and the switching pin 10, is provided. Finally, the stepping mechanism also includes the transport sprocket, which is engaged with the perforation 5 in the display belt and is driven by the switching wheel 9 and consists of the spikes 50. The perforation 5 can be an edge perforation like a narrow film.
  • the transport sprocket (spikes 50) is driven by the ratchet 9 by means of a gear ratio, preferably with a gear ratio of 4: 1 to 8: 1, in particular approximately 6: 1.
  • the sprocket (spikes 50) is not arranged on the ratchet 9, but a transmission gear is provided between the sprocket and the ratchet 9.
  • Such a gear ratio with a gear ratio greater than 1 leads to easy operation of the mechanical display module 1.
  • the transmission gear can be accommodated in that the transport sprocket is provided on one of the deflecting rollers (transport deflecting roller or sprocket wheel), which is preferably designed as a viewing window deflecting roller, and that the transport sprocket (Spikes 50) having deflection roller 6 is positively engaged with the ratchet wheel 9.
  • the sprocket (spikes 50) is arranged separately from the ratchet 9.
  • One of the already existing deflection pulleys is used to attach the transport sprocket. In the exemplary embodiment shown, it is the upper viewing window deflection roller (spiked wheel 6), which in its function for transporting the display tape is also referred to below as a transport deflection roller.

  • Fig. 11 shows the switching wheel 9 of the indexing mechanism from below.
  • the ratchet wheel 9 has in a lower plane 6 to 14, in particular 10 stepping teeth arranged as a ring gear 12 and in an overlying plane coaxial with the outer ring gear 11 with a larger diameter and 36 to 84, in particular 60 teeth.

  • the spike wheel 6 has 5 spikes 50.
  • a complete step of the stepping mechanism therefore corresponds to a three-fifths rotation of the sprocket (spikes 50). Accordingly, a display symbol on the display tape in the exemplary embodiment extends over three engagement openings of the perforation 5.
  • the switching wheel 9 is arranged approximately in the middle of the housing 2, possibly offset from the center of the housing 2, somewhat towards the display window 3.
  • the display module 1 is particularly expedient since the ratchet wheel 9 is mounted on the axis of rotation 26 of the central deflection roller 16.
  • this mounting is such that the ratchet wheel 9 can be rotated independently of a rotation of the central deflection roller 16 and vice versa.
  • 16 sliding surfaces or additional sliding elements can be provided between the switching wheel 9 and the center deflection roller.
  • An axis of rotation 26 with different areas in diameter is also conceivable in terms of construction.
  • the sliding and guiding surface 51 is formed on the housing 2 according to a preferred teaching. This is particularly clear from FIG. 12, because FIG. 12 shows the area around the pinwheel 6 in an enlarged view.
  • Two sliding and guiding surfaces 51 can be clearly seen here, namely a sliding and guiding surface 51 which is concavely formed on the inside on the narrow side and a sliding and guiding surface 51 formed on the inside of the guide projection 41.
  • the sliding and guiding surfaces 51 allow just one with the least possible tolerance Rotation of the sprocket 6 with the sprocket (spikes 50). Nevertheless, in the exemplary embodiment shown and preferred here, the display tape can be easily inserted and removed by lifting the transport deflection roller (spiked wheel 6) towards the open side of the housing 2. Then the display belt can be detached from the sprocket. 9 shows the guide board 25 for the display tape between the viewing window deflection rollers 6.

  • the spring-loaded step switch of the step switch mechanism is opposite the display window 3 in the housing 2 arranged, and preferably in the U-shaped free space 61 between the rear space deflection rollers 14, 15. The space available here due to the guidance of the display tape is therefore used sensibly for the step switch. This is shown very clearly in FIG. 9.
  • Fig. 10 shows in detail the space-saving and reliable construction of the step switch.
  • the step switch has the switching pin 10, which is slidably displaceable in the guide rails 33, 34 on a broad side of the housing 2 and engages with the switching wheel 9.
  • the step switch furthermore has the upstanding from the switching pin 10, which extends approximately parallel to the rear narrow side 27 , serving as a spring bearing plate stop surface 32.
  • the compression spring 8 in particular a helical compression spring, is arranged between the stop surface 32 and the rear narrow side 27.
  • the actuating slides 7 of the stepping mechanism are completely separate from one another.
  • the actuating slide 7 are guided parallel to the upper and lower narrow side of the housing.
  • the clamping parts 36 are arranged along these narrow sides.
  • Guide projections 41 act as sliding guides.
  • Fig. 10 also shows that the slide guides 33, 34 also serve as a guide rail for the switching pin 10 on the broad side.
  • the drivers 17 are attached to the actuating slides 7, in particular to the plate-shaped parts 35, and that the drivers 17 come to rest on the spring plate 32 on the side facing away from the rear narrow side 27.
  • the construction ensures that the compression spring 8 of the step switch on the one hand pressurizes the switching pin 10 in the direction of the switching wheel 9 and, on the other hand, presses the actuating slide 7 in the direction of the rest position.
  • the display tape should be particularly thin. This is an obvious requirement, based on the desire for the greatest possible flexibility of the display tape.
  • Other requirements that are placed on the display tape for example optimal tear resistance, stand in the way of a small thickness.
  • this tape material is optimally thin, on the other hand, it is optimally tear-resistant and finally offers a good base for display symbols.
  • the known display unit for display panels is only suitable for covering the entire display panel over the entire surface.
  • the housing 2 on the narrow side 58 provided with the viewing window 3 and preferably also on the opposite, rear narrow side 27 on the narrow edges is provided with engagement formations 49 for fastening a cover or the like.
  • the engagement formations 49 are designed as grooves, in particular as dovetail grooves.
  • a cover provided with corresponding engagement forms can thus be pushed or snapped "line by line” onto the display modules 1 arranged next to one another.
  • Information carriers for example color foils or the like, can also be inserted between the cover and the display modules 1.
  • the attachment of a cover on the back of the housing 2 of the display module 1 has the purpose of building up a display panel from display modules 1 which can be used on both sides. Then the back of the display modules 1 are also available for information.
