Description

The utility model relates to technical means of ensuring road safety, namely, devices for prohibiting the movement of cars near tram stops during passenger entry / exit.

It is well known that quite often tram tracks pass in the middle of the street, so tram stops are separated from the sidewalks by the carriageway. As a result, passengers entering / leaving the tram car at stops are at risk of being hit by non-rail vehicles traveling in the same direction.

In these cases, the Rules of the Road instruct non-rail vehicles to stop before a tram stop and to let in / out passengers of a tram.

However, the requirement of the Rules of the Road does not guarantee the safety of people, since its implementation depends on a number of subjective and objective factors: the driver’s personality, meteorological conditions, time of day, road condition, etc., which does not exclude the possibility of a car running over tram passengers, including and directly at the bus stop.

As a result of an information search conducted to determine the level of technology, technical solutions directly related to means of restricting the movement of road vehicles at the locations of tram stops were not found.

However, devices for blocking the movement of vehicles are known. Depending on the tasks, the movement overlap is known to be mobile (see, for example, patents No. 2062431, F41H 11/08, publ. 06/20/1996; No. 2309218, F41H 11/08, E01F 13/12 publ. 27.10.2007; No. 2379412, E01F 13/12, published January 20, 2010) devices that are a metal fence consisting of a supporting folding structure in the form of intersecting plates pivotally connected to each other at the intersection, and damaging elements - spikes fixed along the axes of these hinges, and stationary devices - barriers of various designs (see patents: No. 2067940, B61L 29/16, publ. 10/20/1996; No. 2068472, E01F 13/00, publ. 10/27/1996; No. 2213021, B61L 29/04, publ. 09/27/2003).

It is quite obvious that both metal striking barriers and barriers of any type are unsuitable for use on urban highways.

However, as a prototype of the proposed device, a device for blocking the movement of automobile transport is taken - a barrier (patent No. 2213021, B61L29 / 04, publ. 09/27/2003) containing an arrow (beam), fixed movably, with the possibility of rotation in a vertical plane on stationary base-housing, in which the beam electric drive is located, made in the form of a centrifugal mechanism interacting with the beam through the rod.

The disadvantages of the known device are its structural complexity, bulkiness, significant costs for the manufacture, installation and operation. In addition, the known device, being permanently installed, takes up a lot of space on the street, significantly complicating street traffic.

The objective of the claimed utility model is to create a simple, reliable, transportable device with the tram to protect passengers at the tram stops located in the middle of the street.

The technical result of the utility model is to increase the safety of passengers at unprotected stops from moving vehicles, the simplicity and ease of use of the device.

The results of the utility model are achieved due to the fact that in the device for restricting the movement of motor vehicles containing a housing, a movable beam and an electric drive installed in the housing, the movable beam is mounted in the housing with the possibility of sliding along the latter, a longitudinal slotted hole is made in the front wall of the housing, at the ends of which limit switches are installed, and an electric motor with an asterisk mounted on its axis is installed on the right side of the body cavity, while the beam at the ends is connected to drawn therealong chain interacting with an asterisk at the left end of the beam is fixed latch projecting from the slot opening of the housing.

In addition, a signaling device is installed in the right end of the beam, and a reflective coating is applied to the front surface of the beam.

Figure 1 shows the front view of the device (front view), figure 2 is the same with the front cover of the body removed, figure 3 shows a cross section AA of figure 1, figure 4 is a diagram of the placement of the device on the tram. The arrows in figure 4 show the direction of traffic. The device comprises a housing 1 with a cavity 2 and a hole 3, limit switches 4, an electric motor 5 with an asterisk 6, a retractable beam 7, a chain 8 with a tensioner 11, a latch 9 and a signal device 10.

The device operates as follows.

The device is mounted behind the carriage 12 on its any external part, preferably on the bumper, so that its longitudinal axis is located across the direction of movement.

When the tram stops, before opening the car’s doors, the driver turns on the electric motor 5, which starts to rotate the sprocket 6. When the sprocket rotates, the chain 8 interacting with it, moving to the right, pulls the beam 7, which gradually extends along the guides from cavity 2 case 1. The latch 9 connected to the beam slides along the slot 3. In this case, when the latch reaches the right end switch 4, the position of which determines the length of the sliding part of the beam, the latter works, breaks the circuit power to the engine and turns on the warning device 10. After that, you can open the doors of the tram.

The beam, which is extended in this way to a certain distance from the wall of the car, is a kind of barrier that encloses the place of entry / exit of 13 passengers and at the same time, denoting the prohibited area, serves as a prohibitory signal for drivers.

As a signal device, it is preferable to use a red light interlocked with an audible signal intended directly for the tram driver.

At the beginning of movement after a stop, the tram doors are previously closed, then the engine 5 is turned on, the beam is retracted into the housing 1 in the manner described above, after which, when the latch 9 reaches the left limit switch, the device turns off.

The proposed device, being a warning and, to some extent, barrage tool for cars, can improve the safety of passengers when they enter / exit the tram.

In addition, its manufacture, installation and operation do not require large expenses, the device does not interfere with the movement of any vehicles and pedestrians.
