Description

The utility model relates to signaling devices and can be used to warn about the danger of road users.

It is known that with the sudden appearance of a pedestrian on the roadway, a sharp braking of one participant in the movement can lead to multiple collisions of both cars with a pedestrian and cars among themselves. Another potentially dangerous situation in the city is the appearance of a pedestrian at an unregulated intersection or a pedestrian crossing on a multi-lane road: in this case, stopping one (not all) of the traffic participants does not ensure pedestrian safety, since drivers and pedestrians find themselves on a multi-lane road in conditions of limited visibility.

Devices are known which allow a driver passing a pedestrian (or getting ready to miss) to warn the next driver behind about his maneuver. The device according to the patent US 7489236, Chavarria, 02/10/2009 contains a light banner mounted on a car and facing the drivers of vehicles behind. The banner contains a set of lamps located in the form of a sign depicting a pedestrian, which is turned on by the driver (or passenger) when a pedestrian appears on the roadway. A warning banner of this design is, firstly, opaque to the driver, which reduces the viewing angle through the inner rearview mirror, and secondly, expensive due to the technological features of the manufacture.

Various designs of light information devices (transparencies) that can be used for the described purposes are described. Thus, the information device according to the patent RU 47556 U1, Koval et al., August 27, 2005, is known, which contains a flat board made of a transparent material, at least on one surface of which information signs are applied, and light devices based on LEDs installed at least at least on one end side of the flat board with the possibility of introducing radiation into the flat board, with at least one end side having a reflective coating. LEDs can be installed outside the end side of the board or in recesses to accommodate the luminous part, and in front of each LED there is a section without a reflective coating. LEDs at their location are covered by a casing. Information signs are made by engraving or gluing a light-scattering film. This device involves special processing of the end face of the transparent plate to introduce the light flux, such as, for example, incomplete deposition of a reflective coating, the formation of recesses for LEDs, etc. Such events inevitably complicate the manufacturing cycle of the device and increase its cost.

A known light signaling device (RU 62464 U1, Vlasov et al., 04/10/2007), which contains a transparent sheet, on the back of which there is a transparency of reproducible characters and a mirror surface, and light sources made in the form of light-emitting diodes are installed on the front side of the sheet. However, when mounted on the rear window of the car, the mirror surface, although it will increase the brightness of the glow of the characters, will nevertheless tint the driver’s rear view.

Closest to patentable is a light communication device for car drivers while driving (RU 78973 U1, Dzhumayan, 12/10/2008 - prototype). The device comprises a screen with a light emitting inscription and a power button associated with the power unit of the car. The screen is made in the form of a flattened transparent plate with rounded side faces, on which fastening protrusions are made for fastening elements, for example, to a car glass. The screen can be fixed to the car glass using double-sided tape or through suction cups. The device may have a time relay that controls the duration of the glow of the screen with the inscription.

However, this device is not intended for instantaneous warning light in an emergency due to the lack of controls directly at hand for the driver.

This utility model is aimed at improving the device designed to inform road users about the presence of a pedestrian in conditions of limited visibility, in particular, due to the presence of a vehicle ahead.

The light information device for warning drivers about the appearance of a pedestrian contains a transparent plate with the characters printed, an LED illuminator connected to the end face of the plate connected to a control unit connected to the vehicle’s power supply system, and means for fixing the plate to the rear window of the car from the passenger compartment.

The difference is that the control unit includes a remote control having control buttons for turning the illuminator on / off in the button hold mode and in the automatic shutdown mode with a delay, while the remote control is configured to communicate with the control unit via a wireless radio channel and is attached to the steering wheel.

The LED illuminator is made in the form of a self-adhesive LED strip attached to the inner shelf of an opaque cover of a U-shaped profile, attached along the inner side walls to the edge of the said plate.

The other edge of the plate is profiled with the formation of a protrusion in its middle part for attaching an adapter and a hinge connected with a suction cup with vacuum fixation for attaching to the car glass, the protrusion ridge having a number of holes for fixing the adapter in one of the positions relative to the center of the plate.

The device can be characterized by the fact that the plate is made of colorless polymethyl methacrylate, the symbols are made in the form of recesses and are formed by milling and / or pyrootyping to a depth of at least 2 mm, the side walls of the recesses being inclined outward and make an acute angle with the plane of the plate, and also that the symbols are microrelief on the surface of the plate formed by knurling or abrasive machining.

The device can be characterized by the fact that the plate with a thickness of 3-5 mm can have a rectangular shape, the dimensions of which are: length 450-500 mm, width in the protrusion zone 150-220 mm, width outside the protrusion zone 90-160 mm, or equilateral a triangle with a rib length of 200-400 mm.

The device can be characterized, in addition, by the fact that the remote control is attached to the steering wheel with double-sided adhesive tape, and by the fact that the symbols form the word “PEDESTRIAN” or “PEDESTRIAN ON THE ROAD” or a conditional graphic image of a pedestrian, as well as the fact that P- the shaped profile is attached with screws and nuts through the through holes in said plate.

In another embodiment of the light information device, the plate is made of colorless flexible plasticized polyvinyl chloride in the shape of a car glass and is attached using a transparent double-sided adhesive tape close to the glass surface.

EFFECT: increased efficiency of supplying a light signal about the appearance of a pedestrian for drivers of cars following behind.

A block diagram of an information device housed in a passenger compartment is shown in FIG. A transparent plate 2 is attached to the rear window 1 of the car from the side of the passenger compartment - a banner with printed characters and a illuminator, which is connected by wires 3 to the control unit 4 connected to the vehicle’s power supply system. The control unit 4 is connected via a wireless radio channel 5 to a remote control 6 having control buttons for turning the illuminator on / off in the button hold mode and in the automatic shutdown mode with a delay. The remote control 6 is attached to the steering wheel 7, for example, by means of double-sided adhesive tape.

Figure 2, 6 shows a variant of the design of the device, which is mounted on the rear window 1 using a suction cup 8. On one edge 9 of the plate 2, a illuminator 10 is mounted, in the middle part of the plate 2 made of colorless polymethylmethacrylate, symbols 11 are placed, which are made in in the form of recesses or microrelief on the surface of the plate. The edge of the plate 2 is profiled with the formation in the middle part of the protrusion 12 for attaching the adapter 13 and the hinge 14, connected to the suction cup 8 with vacuum fixation for attachment to the car glass. The crest of the protrusion 12 has a number of holes 15 for fixing the adapter 13 in one of the positions relative to the center of the plate 2. The plate 2 with a thickness of 3-5 mm can have a rectangular shape, the dimensions of which are: length 450-500 mm, width in the area of the protrusion 150-220 mm, width outside the protrusion zone 90-160 mm. The plate 2 may have the shape of an equilateral triangle with a rib length of 200-400 mm (Fig. 4) and a similar fastening element to the rear window 1 using a suction cup (not shown conventionally in Fig.).

Symbols 11 form the inscription "PEDESTRIAN" or "PEDESTRIAN ON THE ROAD", etc. or conventional graphic image of a pedestrian (pos. 111). Symbols 11, 111 in the form of recesses (Fig. 5) are formed by the method of milling and / or pyrootyping to a depth of not less than 2 mm, and the side walls 16 of the recesses 17 are made inclined outward and make an acute angle with the plane of the plate 2. All corners are rounded with a radius of 10 mm. The inscription “PEDESTRIAN” with dimensions in the plane of the plate 460 × 65 mm is made by milling along the midline with a depth of 2 mm, the font width in the panel plane is 4 mm. The milled faces make an angle of 45 degrees with the plane of the plate, which ensures efficient light scattering on the word “PEDESTRIAN” in directions close to the normal to the plane of the plate. The milled surfaces have some roughness and are not further processed after milling, which increases the efficiency of the glow of the inscription “PEDESTRIAN”. In addition, the absence of additional processing simplifies the manufacturing process and reduces the cost of the device. Symbols can be made in the form of a microrelief on the surface of a plate formed by knurling or abrasive processing according to known technology.

The geometric parameters of the “PEDESTRIAN” inscription are optimized for maximum ease of perception in the traffic stream under various, including adverse, weather conditions. In addition, the geometric parameters of the inscription “PEDESTRIAN” were selected with the readability calculation at an angle of up to 45 degrees relative to the longitudinal axis of the car, which allows the device to be used efficiently on multi-lane roads (up to four lanes). The above fully applies to the implementation of the recesses of the graphic image of the pedestrian (pos. 111).

In another embodiment of the light information device (FIGS. 3, 7), the rectangular or triangular plate 2 is made of colorless flexible plasticized polyvinyl chloride according to the curvature of the glass 1 of a car and is attached using a transparent double-sided adhesive tape 18 of increased strength (for example, 3 M VHB) close to the glass surface 1.

The LED illuminator 10 (Fig. 9) is made in the form of a self-adhesive LED strip 20 connected by an adhesive side 21 to the inner shelf 22 of an opaque cover 23 of a U-shaped profile made of PVC, attached along the inner side walls 24 to the edge of the plate 2. The fastening can be in one piece and collapsible and carried out through the holes 25 screws and nuts. Self-adhesive LED strip is fixed on the inside of the U-shaped PVC or rubber profile with dimensions of 8x15 mm and a wall thickness of 1 mm. LED strip parameters: width 8 mm, height 2 mm, length 450 mm, 27 LEDs, power consumption 2.16 watts. A U-shaped profile with a fixed LED strip is fixed with screws and nuts in three places through the through holes in the transparent plate. The lighter 10 is fixed so that the light flux from the LED strip 20 is directed to the end of the transparent plate 2. The power supply wires 3 of the LED strip 20 are supplied to the illuminator 10 from one side. The power of the illuminator is optimized in terms of the maximum perception of luminous characters at different times of the day and under different weather conditions, as well as the minimum material consumption.

The suction cup 8 is connected to a transparent plate 2 through a mounting adapter with holes 15 for screws (see Fig. 6). Four through holes 15 are located on the protrusion 12 of the plate 2, so that the mounting adapter 13 can be installed in three different positions, which simplifies the placement of the device on the rear window for cars of various models. The hinge 14 allows you to install the plate 2 in an upright position on the glass 1 with any inclination. The vacuum fixation of the suction cup 8 provides a reliable connection to the glass surface, regardless of temperature and humidity in the passenger compartment, as well as a multiple safety factor by weight of the device. Mounting the device on the suction cup 8 allows you to completely avoid structural changes in the vehicle interior when installing the device, and if necessary, quickly change the mounting location or completely dismantle the device, for example, when transporting bulky goods.

The control unit 4 is installed under the skin of the passenger compartment and is connected by wires 3 to the vehicle electrical system using couplings (taps) without breaking the factory wiring. The remote control 6 (Fig. 9) is mounted on the steering wheel using double-sided adhesive tape in a convenient place in accordance with the preferences of the driver. The remote control 6 is powered by a non-rechargeable battery. The remote control 6 is connected to the control unit via a wireless radio channel at a frequency of 433 MHz or 2.4 GHz. The control unit can have several operating modes: manual on / off (manual mode), manual on and subsequent automatic shutdown with a delay (delay mode), change in brightness (rheostat mode), on / off blinking (blinking mode). The delay time is programmed in the range of 0.5 sec. up to 1 hour. The blinking mode is characterized by a frequency of 1 Hz. The remote control 6 with two buttons 61, 62, corresponding to the manual mode and the delay mode, can be fixed on the back of the steering wheel 7. The difference in the shape and size of the buttons 61, 62, as well as the convenience of their location on the console 6 allows you to use them by touch, which further accelerates the response of the driver in an emergency.

In the patented device, increasing the speed of supplying a light signal about the appearance of a pedestrian is ensured by the location of the controls directly on the steering wheel in a place convenient for the driver, which allows you to turn on the warning signal immediately when a pedestrian is found on the road or in a dangerous vicinity. At the same time, a warning signal is provided by the driver without taking his hands off the steering wheel and does not interfere with emergency maneuvering associated with taxiing, which is extremely important in an emergency on the road.
