Изобретение относитс к средствам, информации , например пассажиров гражданской авиации,и предназначено преимущественно дл использовани около посадочных трапов самолетов.The invention relates to information means, for example, civil aviation passengers, and is intended primarily for use near aircraft landing ramps.

Известен индикатор, содержащий корпус , в котором на общей оси установлены цифровые барабаны на втулках, св занных с пружинными фиксаторами, ручки управлени и лампы подсветки, закрепленные в корпусе (1.A known indicator comprises a housing in which, on a common axis, digital drums are mounted on hubs associated with spring clamps, control knobs and backlights mounted in the housing (1.

Однако механизм управлени цифровыми барабанами сложен и работает, как правило, от электропитани . Это не позвол ет применить индикатор в местах, где подвод электроэнергии или затруднен, или вообще невозможен .However, the control mechanism of the digital drums is complicated and works, as a rule, from the power supply. This does not allow the indicator to be used in places where the supply of electricity is either difficult or impossible.

Целью изобретени вл етс упрощение индикатора.The aim of the invention is to simplify the indicator.

Эта цель достигаетс тем, что он содержит шаровой стопор, закрепленный на корпусе , горизонтально-цилиндрическую опору, выполненную в виде вставленных друг в друга трубчатых валиков, каждый из которых св зан с соответствующей ручкой управлени и с втулками цифровых барабанов, снабженных шлицевыми впадинами по поверхности осевого отверсти , фиксатор трубчатыхваликов относительно корпуса в виде звездочки, укрепленной на наружном валике, снабженном радиальными отверстн ми, выполненными против шлицевых впадин, и св занной с шаровым стопором, и шариковыйThis goal is achieved by the fact that it contains a ball stop mounted on the body, a horizontal-cylindrical support made in the form of tubular rollers inserted into each other, each of which is associated with a corresponding control knob and with the sleeves of digital drums provided with splined hollows along the surface. an axial bore, a retainer of tubular holders relative to a casing in the form of an asterisk, mounted on an outer roller, provided with radial bores, made against spline depressions, and connected to a ball with supports, and the ball

фиксатор, щарики которого,размещеиные в радиальных отверсти х наружного валика, св заны с внутренним валиком, снабженным расположенными против каждого шарика кольцевыми выточками с кулачками, смещенными относительно друг друга между ос ми. На фиг. 1 изображен предложеиный индикатор во фронтальной проекции при условно сн той панели кожуха со смотровым окном и частичном разрезе дисковых носителей информацнонных знаков с трубчатыми вали5 нами; на фиг. 2 - механизм включени и передачи дисковому носителю крут щего момента в положении дл каждого дискового носител в поперечном разрезе по А-А, В-В, С-С и D-D.a retainer, the balls of which are placed in the radial openings of the outer roller, are associated with an inner roller provided with annular recesses opposite each ball with cams displaced relative to each other between the axes. FIG. 1 depicts a frontal projection indicator with a conditionally removed casing panel with a viewing window and a partial section of the disk carriers of information signs with tubular valles5 by us; in fig. 2 shows the mechanism for turning on and transmitting disk torque to the carrier in position for each disk carrier in cross section along A-A, B-B, C-C and D-D.

Claims

The indicator consists of a casing 1 having a front panel with a viewing window (conventionally removed) through which information signs 2 are visually exposed on the cylindrical surface of the disk carrier of signs 3 made of transparent material, for example, polystyrene. The disk carriers of the indicia 3 are reinforced freely by a ring 4. on a horizontally cylindrical support consisting of an outer tubular roller 5 with a rotation handle 6 and an inner tubular roller 7 inserted into it with a rotation handle 8. Each disk carrier of characters 3 is equipped with a plate spring 9, which protects it from arbitrary rotation by securing the tooth 10 at the end of the spring with a recess 11 on the disk carrier of characters and in the sleeve of the disk carrier, spline hollows 12. The ball 13 is freely placed in the radial hole 14 on the housing of the outer tubular roller 5 in the annular groove 15 on the surface of the inner tubular roller 7 having a clamp 16. The clamp of the tubular rollers relative to each other, from the radial and, accordingly, axial cm another 1H1 consists of a ball 17 placed in the radial hole of the inner roller 7, spring loaded with a plate spring 18 and engaging with radial holes 19 opposite to the radial holes 19 on the outer tubular roller 5, in combination with the bolt 20, radially screwed into the outer tubular roller 5 and having a protrusion at the end, preferably in the form of a cone, which is located opposite the annular groove 21 on the inner tubular roller 7. The clamp of the tubular rollers relative to the casing is made in the form of an asterisk 22, reinforced minutes on the outer tubular roller 5, which includes its teeth into engagement with scharovsh stopper 23 fixed on the casing 1. Inside the casing on both sides of disk media mounted characters illumination bulb 24 for enhancing the contrast information signs exhibited in the viewing window. For the convenience of selecting the disk medium of the sign that needs to be rotated and thereby changing the exposed value of the sign, the order number 6 is marked on the end of the handle 6, for example, when it is read to the right, and the handle 8 is provided with a pointing arrow. The indicator works as follows. The illumination lamps are turned on and, rotating the tubular inner roller 7 with the help of knob 8, the protrusion 16 acts on the ball 13. Moving along the opening 14, the ball 13 enters the slotted groove 12 of the disk carrier 3 and engages it with the inner full outer roller 5. Then rotating by the handle 6, the rotational moment is transmitted to that disk character carrier, which is engaged with the roller 5. Its rotation is carried out until such time as the necessary informational sign is not in the viewing window. After that, go to the rotation of the other disk media. To do this, rotate the knob 8 until its index arrow is offset with the number of the disk carrier on the end of the knob 6, on which the exhibited sign needs to be changed, and then the knob 6 is rotated again, and through it the chosen disk medium before the necessary information sign is installed window During rotation of one or another disk carrier, the spring 9 is pressed out by the disk carrier body, and the ball stopper 23 is the teeth of sprockets 22, which return to their original position when the next initial position of the disk information characters is set. Claims of the invention An indicator comprising a housing in which digital axles are mounted on a common axis on bushings associated with spring clamps, control knobs and backlight lamps mounted in the housing, characterized in that, in order to simplify the indicator, it contains a ball stonor mounted on the housing, a horizontally cylindrical support, made in the form of tubular rollers inserted into each other and connected by a ball retainer, each of which is associated with a corresponding control knob and with the sleeves of digital drums new, provided with slotted hollows along the surface of the axial bore; a clamp of tubular rollers relative to the housing in the form of an asterisk, mounted on an external roller, provided with radial holes, made against the splined hollows, and associated with ball stop bars, and a ball retainer, balls which are located in the radial holes of the outer roller, are associated with an inner roller, provided with annular recesses with cams located opposite each ball, displaced relative to each other between the axes.
