Abstract

The inventive utility model relates to security devices and can be used for acoustic signaling in case of unauthorized entry into a passenger compartment. The technical solution of the claimed utility model, a security device, is based on the installation of the device body on the wall of the compartment and the connection of an element to be removed from the contact device, for example, a removable rod including an alarm, with a flexible, non-stretchable element, for example, a chain with an element of an opening compartment door, for example, a lock coupe. The housing of the claimed utility model is a security device with fasteners made, for example, of plastic and contains a power device, a signal and contact device. The fixed position of the removed rod in the guide sleeve of the contact device is provided by a curly spring installed in the slot of the guide sleeve so that its position coincides with the middle of the annular groove of the removed rod inserted into the sleeve. Switching of the contact group included in the power circuit of the signaling device is carried out by the pusher, which through the hole in the guide sleeve of the contact device partially overlaps the internal hole in it in the absence of a removable rod. The power source of the device can serve as an autonomous source, for example, elements of the type "AA", and the electrical network of a railway carriage, for example, powered by a battery of batteries. The formula of the claimed utility model is multi-link and contains three points.

Description

The inventive utility model relates to protective devices and can be used for acoustic signaling in case of unauthorized entry into passenger compartments.

Known devices and locks containing a housing, spring-loaded latches and pads (1, 2 and 3).

However, these devices are not reliable enough and are not protected from unauthorized removal or neutralization. For example, in the case when the compartment door is "pushed" from the corridor of the car.

The closest analogue in technical solution to the claimed device is the device according to the Patent for utility model No. 41480 "Security device".

The security device according to the Patent for utility model No. 41480 is shown in figure 1, figure 2 and figure 3.

The device comprises a housing 1 (Fig. 1) made of two halves 3 and 4 connected, for example, by screws 2 (Fig. 1), between which a power supply 13 (Fig. 1) is placed and two elastic elements 9 and 16 are fixed, and on the surface of the housing 1 is placed the first contact device (Figure 2), consisting of a spring-loaded lever 17 and normally open contacts 20, overlapped by the housing rigidly mounted on the housing 1

security device (Fig. 1 and Fig. 3), for example, with screws, of a signaling device 5 (Fig. 1), in the housing of which normally closed contacts 23 (Fig. 3) are placed, forcibly opened by a removable disconnecting rod 24 (Fig. 3) fixed in a metal sleeve 25 (Figure 3), connected by a chain 26 (Figure 3) with a fixing device 27, for example, a hook.

The device installed on the lock 7 of the compartment (FIG. 2 and FIG. 3) is held by elastic elements (9 and 16), covering the lock handle (10) from above and the neck of the key head (12) from below, while the locking device (27) is fixed to the fittings coupe.

When you turn the head of the key (12) of the lock, the spring-loaded figured lever 17 (Figure 2) closes the open contacts 20 (Figure 2) and turns on the acoustic signal, and when the door is opened, the acoustic signal is turned on due to the removal of the breaking rod 24 (Figure 3) ) and the closure of the forced open contacts 23 (Figure 3).

The disadvantage of this device is the difficulty of removing it from the lock case (Figure 2) by compartment passengers. So, for example, to remove the device, you must initially pull down the lower elastic element 16 (Figure 2), separate it from the head of the key 12 of the lock, and then separate the body of the device from the lock body 7 (Figure 2). When this inevitably occurs the tension of the chain 26 (Figure 3), connected to the disconnecting rod 24 (Figure 3), and, given the fact that the acoustic signal is turned on with a slight extension of the rod 24, the latter must be additionally held.

In addition, the second function of the device is the inclusion of an acoustic signal by a spring-loaded figured lever 17 (Figure 2) when turning the head

the key 12 (Figure 2) of the lock is not a primary function, but an additional one, since according to the statistics of transport law enforcement agencies, unauthorized entry into the compartment in most cases occurs after the lock is “released”, in which this function is redundant, complicating the design of the device and becoming more expensive product.

The technical result of the claimed utility model is a security device (Figure 4, Figure 5 and Figure 12) is to increase its reliability.

This is achieved by the fact that the housing of the device 28 is installed, for example, by means of screws or hooks, in a compartment on the wall 46 to the right of the doorway, moreover, a removable element of the contact device that includes an alarm, for example, the removable rod 38 is connected to the element of the opening door 49 compartment, for example, with the handle 47 of the lock 48, a flexible, non-stretchable element, for example, a chain 40 with a locking element, for example, with an oval ring 41.

At the same time, the processes of both connecting the device to the security mode of the compartment and disabling this mode are greatly simplified, the design of the device is simplified and, as a result, the reliability of the product is increased.

The inventive device comprises a housing 28 (Figure 4 and Figure 5), made, for example, of plastic. On the outside of the upper and lower walls of the housing there are tides 29 with holes 30 for fasteners, for example, screws or hooks. A power device 31, an electronic acoustic signaling device 32, and a contact device consisting of a guide sleeve 33 made, for example, of plastic, of a contact group 34 with a pusher 35 (FIG. 5, FIG. 8) are placed in the internal volume of the device case (FIG. 5); and Fig. 9) and the fixing spring 36. In this case, the ends of the guide sleeve 33 through the holes in the side walls

the housing 28 protrude beyond it and the guide sleeve 33 itself is rigidly fixed to the housing, for example, using nuts 37.

The removable rod 38 (FIG. 6), made of, for example, plastic, has an annular groove 39 and is connected to a chain 40 ending in an oval ring 41 for connecting to the handle 47 of the compartment lock 48 (FIG. 12). The annular groove 39 is designed to fix the end position of the removed rod 38 in the guide sleeve 33 (Fig. 5 and Fig. 9) with a fixing spring 36, for example, a curly U-shaped spring (Fig. 5 and Fig. 7). The locking spring 36 is installed on the guide sleeve 33 so that part of it through the slit-like cut 42 in the guide sleeve 33 in the absence of a removable rod 38 partially overlaps the inner hole of the sleeve 33 (Fig.7). In this case, the position of the fixing spring 36 on the guide sleeve 33 coincides with the middle of the annular groove 39 (Fig.6) on the removable rod 38 (Fig.6) while the removable rod is fully inserted into the guide sleeve 33 (Fig.9).

The contact group 34 (Fig. 5, Fig. 8 and Fig. 9) is fixed to the housing of the device 28, for example, with screws. The pusher 35 of the contact group 34 at one end is rigidly fixed to one of the contacts of the group. The other end of the pusher in the absence of a removable rod 38 through the hole 43 is in the inner hole of the guide sleeve 33 (Fig.5 and Fig.8) so that it partially overlaps the inner hole of the sleeve and the contact group 34 is in the closed position.

When the removable rod 38 is fixed in the guide sleeve 33, the contact group 34 is in the open position (Fig. 9).

With a long break in operation of the inventive device, for example, when storing a removable version of the device in a compartment

the car’s conductor, in the guide sleeve 33 of the contact device, from the side opposite the compartment door, a removable dummy rod 44 is installed (FIG. 10), made of, for example, plastic.

The design of this rod is distinguished by the absence of a shank to which the chain 40 is attached, and by the location of the annular groove 45, which, like the groove 39 (FIG. 6), ensures the fixation of the position of the rod 44. Removing the dummy rod 44 is done by “extruding” it with a removable rod 38, installing the latter in the inner hole in the guide sleeve 33 from the side of the compartment door.

The purpose of the contact device is to control the power supply circuit of an acoustic signaling device, which is used, for example, as an electronic tone generator and acoustic emitter.

The design, dimensions and embodiment of the device (removable, portable or stationary) are determined by the type of power supply selected. An example of a possible functional electrical circuit for three different options for power sources of the device is shown in Fig.11.

In the case of using, for example, "AA" type elements as a power source, contact group 34 can be connected directly to the power source, bypassing the normally closed contacts 2 and 3 of the deenergized relay K, since this eliminates the need for either a relay or a voltage converter. The dimensions of the claimed device are minimal and the device can be made both for rigid fastening on the wall of the compartment and in the form of a removable structure mounted on the wall of the compartment, for example, using hooks.

The advantage of this option is the small size of the device, and the disadvantage is the need for periodic replacement of batteries.

If a car is used as a power source (from a battery of batteries with a voltage of 54 Volts or 110 Volts) to power the device, you first need to lower the voltage using a voltage converter, for example, a quenching resistor, and dissipate the power released in this case as heat. This requires the presence of an additional ventilated volume of the device body, and the device design can only be made for rigid fixing to the compartment wall.

At the same time, the voltage converted to the required value after the voltage converter can be directly applied to contact group 34, bypassing contacts 1 and 2, since this eliminates the need for relay K.

The advantage of this option is the lack of the need for periodic replacement of batteries. The disadvantages are a significant complication of the device due to the need to convert the input voltage of the car network to the value necessary for the security device to work, as well as the large dimensions of the device compared to the previous version.

In the case when the device is supposed to use universal power, that is, automatic switching to "AA" cells when the batteries are turned off, the dimensions of the device become even larger than in the previous version and the power device becomes even more complicated.

With this option, the input voltage from the car network is fed to the coil of relay K, (while the contacts of relay 1 and 2 are closed), then to

the voltage Converter and then the converted voltage through the contacts of the relay 1 and 2 is supplied to the contact group 34 of the inventive device.

In the absence of voltage from the car network, the relay coil K is de-energized, contacts 1 and 2 are open, and the voltage from the power source, for example, from "AA" type elements, through normally closed contacts of relay 2 and 3 is supplied to contact group 34 of the claimed device.

Depending on the specific operating conditions of long-distance trains, all three options find practical application.

The use of the inventive device to protect the compartment from unauthorized penetration of unauthorized persons into it is shown in Fig.4 and Fig.12.

The housing of the claimed device 28 through the holes 30 is fixed, for example, using screws, or is put on hooks on the side wall 46 of the compartment to the right of the doorway. The removable rod 38 is inserted and fixed in the guide sleeve 33 of the contact device (Figure 9). In this case, the pusher 35 of the contact group 34 abuts against the removable rod 38 and is withdrawn from the inner hole of the guide sleeve 33, and the contact group 34 is open. The oval ring 41 connected to the chain 40 is fixed on the handle 47 of the lock 48 of the door 49 of the compartment. The length of the chain 40 is selected in such a way as to minimize sagging.

In any case, when the door is opened (“rolled back”), the chain 40 will stretch and with the door “rolled back” 49 continuing, the removable rod 38 fixed at the other end of the chain 40 first consecutively overcomes the elasticity of the curly U-shaped spring 36 and disengages the annular recess 39 with her. With further movement of the rod 38, part of the inner hole of the guide sleeve 33 will be freed. In this space

through the hole 43, under the action of the elasticity of the contact connected to it, the pusher 35 moves from the contact group 34. As a result, the contact group 34 closes, power is supplied to the acoustic signaling device, and an alarm is triggered.

The alarm is turned off by disconnecting the oval ring 41 of the chain 40 from the handle 47 of the compartment lock 48 and installing the removable rod 38 in the guide sleeve 33 of the contact device to a fixed position.

If it is necessary to open the door from the inside of the compartment without triggering an alarm, it is enough to disconnect the oval ring 41 from the handle 47 of the lock 48.

The inventive device allows you to protect the passengers of the compartment and their personal belongings from unauthorized entry, warning about opening the door of the compartment, regardless of whoever it opened.
