Description

DETAILED DESCRIPTION OF THE INVENTION As is well known, a variety of motor vehicle anti-theft devices are available on the market. However, these devices traditionally consist of modifying the electrical circuitry within the vehicle. Other devices are smaller, but modified versions of automobile fuel supply systems. Unfortunately, a more effective device that combines both properties and uses fewer parts (as is the case with the present invention) is not readily available.

Other modifications are also known in the art for detecting possible mechanical failures in advance. While some of these modifications are generally considered good, each currently suffers from problems, such as the use of too many parts and the overly complex installation.

As those skilled in the art will recognize, a variety of materials and a variety of well-known components may be used to accomplish the foregoing. Therefore, these will not be explained in detail.

In general, automotive anti-theft devices currently on the market are characterized by the installation of a series of components and parts. Such components and parts are controlled by special keyed locks.

This lock can be activated if desired. This device is electrically activated and if an intruder attempts to open any part of the vehicle such as a door, trunk or hood, the device will sound an alarm to indicate the presence of an abnormality. The alarm is a bell or buzzer and is turned off only by closing the circuit with the key or removing the battery, or when the battery current is consumed.

Alarm and non-alarm anti-theft devices currently on the market operate on the fuel injection line, which is required to open and close the carburetor brake. However, these devices can be easily modified by filling the carburetor with a drop of fuel, allowing the fuel to be consumed, and repeating this operation as many times as necessary.

The improved anti-theft device described herein, which also protects the vehicle against tie rod and piston jamming, has many advantages over other devices.

It is an object and feature of the present invention to provide a novel and simple structure anti-theft device. Although the device of the present invention uses known components and materials, it is a new and unique combination of those components and other components that results in a novel anti-theft device.

In fact, the prior art includes a variety of anti-theft devices for motor vehicles. It is an object and feature of the invention to combine an anti-theft device with a dual function, such as the one described herein, which operates in a practical, easy and completely effective manner.

As mentioned at the beginning of the description, a new and improved anti-theft device for an automobile is concerned with protection against connecting rod and piston jamming. A brief description of the prior art has been provided so that the scope of the invention may be understood.

One of the objects of this invention is to provide an improved anti-theft device for a motor vehicle that is more effective and economical than conventional anti-theft devices.

Another object of the present invention is to provide an anti-theft device that has fewer parts and is easy to install.

Still another object of the present invention is to provide an anti-theft device that notifies a user of the occurrence of a serious mechanical failure and automatically and instantaneously stops a vehicle upon detection of the mechanical failure.

Another object of this invention is to provide an anti-theft device that adds small components to provide an alarm for mechanical problems such as overheating of the engine or water. The anti-theft device can also alert you to mechanical damage to the transmission case, gearbox, differential case, or hydraulic brake system, making it more efficient and useful than traditional devices. Acts as an anti-theft device.

Another feature of the invention is the ability to optionally reset the operation of the vehicle even after a malfunction has been detected by the anti-theft device, so that the vehicle can be stopped automatically and instantaneously.

Using this configuration, for example, the driver can drive the vehicle only long enough to pull over to the curb to avoid a traffic accident or to reach a safety zone or a service station to repair the vehicle. .

Details of the features of this improved anti-theft device that protect against erected connecting rods and piston jamming are set forth in the following detailed description with reference to the accompanying drawings.

Other components are used in this description, but since they are well known and their use is common, they will be briefly discussed here.

In a non-limiting embodiment of the present invention with reference to the accompanying drawings, an improved anti-theft protection device for a motor vehicle against connecting rod and piston jamming operates as a whole in combination and furthermore essentially a relay and a connector base specifically designed for this primary relay;
An emergency restarter, a secondary relay and a series of separately configured valves to measure oil pressure in the engine, transmission or differential case, brake system or to measure overheating of the feed water, alarm or buzzer and It is composed of several parts, including a connecting device. Abnormalities in any of the engine systems mentioned above can be recorded on the vehicle's instrument panel by means of an electric light or a buzzer. Additionally, a failed engine system can be shut down instantly upon reaching a preset value and reset as desired by the vehicle operator to pull the vehicle to a curb, road edge, or other safe location.

Generally, anti-theft devices currently on the market are operated by a motorized device that, when the electrical current is interrupted, provides an alarm to indicate possible theft of the vehicle. The operation of all such anti-theft devices is stopped by a lock connected to the battery.

In the device described below, the vehicle will not start in any way unless the owner wishes to do so, and the use of the alarm by the owner is optional.

As previously mentioned, my anti-theft and protection device for connecting rod and piston jamming consists of two relays, devices that are always interrupted or corrected in the event of a fault. These relays open and close the circuit, and removing the relay stops the passage of current from the battery. One of these relays is the primary relay 20, which in this example is rectangular 21 and has at its bottom a series of legs or surrounding outlets 22 with a central shaft 23. This primary relay 20 has a capacity of 12 volts, 10 amps or 250 volts and can be coupled or disconnected at any time to a connector base 24 specifically designed to accommodate said primary relay 20.

The connector base 24 is also rectangular in shape and has a series of radial and circular perforations 2G in its upper central portion 25.

A central shaft 23 of the primary relay 20 and a series of legs or surrounding outlets 22 for attaching the various engine equipment to be protected are inserted into a bore in the upper central portion of the connector base 24.

Like a fortune, the connector base 24 is specially designed. Especially regarding the installation of the perforation 26, the primary relay 20
If it is missing, for example, if someone tries to steal your car, the circuit cannot be "bridged."

The connector base 24 also has an upper portion 2 on its parallel side walls 27 which is indicated for installation or connection purposes by numbers or letters.
It has a series of connection cavities or holes 28 actuated by a series of devices or screws 29 provided in the 5. The capacity of connector base 24 is 10 amps and 380 volts.

FIG. 3 shows the secondary relay 30. In this example,
The secondary relay 30 has a rectangular shape with a locking portion 30, and is fixed to the inside or lower portion of the instrument panel of the vehicle by conventional fastening means. The secondary panel 30 has four flat metal legs 32 separately arranged at its bottom, one of which 33 is connected to the connector base 24. Another connection 34 interconnects the secondary relay 30 to the vehicle battery. The third connecting portion 35 is connected to an emergency reset device 36 . The capacity of the secondary relay 30 is 12 volts and 40 amperes.

FIG. 4 shows the reset device 36. In this embodiment, the reset device consists of two upper flat metal protrusions, one protrusion 37 is connected to the leg 34 of the second relay 30, and the other metal protrusion 38 is connected to the coil of the vehicle. Ru. The emergency reset device also includes a button 39 that opens and closes a circuit to reset operation of the vehicle. This emergency reset device 3G is fixed to the chassis of the vehicle with two hexagonal nuts 40.

In other embodiments, a series of valves (supplies) connected to the connection cavity or hole 28 may be installed to measure oil pressure or temperature.

The anti-theft device of the present invention can also be installed in various engine systems in which it is desired to protect indicator valves, in order to act as a protection device against connecting rod and piston jamming caused by overheating due to lack of water pressure or oil pressure, for example. This valve is specifically configured to the desired value.

Valves used for this purpose are manually calibrated and usually factory calibrated, but the values to which the valves are calibrated are too high. As a result, the level at which the vehicle's instrument panel indicator indicates an abnormality or failure in the engine system is too late to prevent connecting rod and piston jamming or to shut down the vehicle before serious engine damage occurs. Can not.

For example, in regular gasoline vehicles, the first commercially available valves used to indicate temperature were calibrated to indicate an abnormality when the temperature was around 115 degrees Celsius. However, at this temperature, major failures are easily caused as the normal heating of this type of vehicle is between 90 and 94 degrees Celsius. As a result, it is not appropriate for the valve to be calibrated to 115-120°C. In this example, the valve must be calibrated to indicate a temperature significantly lower than the commercially available valve temperature, eg, 102°C.

At that temperature, an indicator on the instrument panel activates, stopping the vehicle immediately and allowing the operator to confirm the failure and avoid major engine damage.

The same is true for valve command oil pressure, which is commercially calibrated to 31b/In2 or 0.25 kg/cJ. In this embodiment of the rod and piston anti-jamming system, the valves used must have different calibrations based on the life of the vehicle. For example, in a new car, the valve is calibrated to a pressure of 141b/ln2 or 1 kg/cJ, and in a used car, the valve is calibrated to a pressure of 71b/in'' or 0.
．． Must be calibrated to a pressure of 5 kg/c-.

The above also applies to diesel engine vehicles, but because diesel engines operate at lower temperatures than gasoline-powered engines, specifically 80-85 degrees Celsius, the valves used may be calibrated in other ways. Ru. As a result, the valves used commercially in diesel engines are 105-11
If it is 0°C, install a valve calibrated to 92°C, and when the engine reaches this temperature, the indicator will record this and stop the engine damage by immediately stopping the vehicle. Calibration of oil valves for diesel engines is the same as described above for gasoline engines.

In the same manner as described for temperature and oil level indications, install valves configured for various values.
It also predicts and indicates possible failures in the transmission case, differential case or brake equipment.

Even in such cases, possible damage to the above-mentioned parts of the vehicle can be avoided by automatically stopping the vehicle when a certain value is reached.

As previously mentioned, a dual hydraulic and temperature indicator valve is connected to the primary relay via a connection cavity or hole in the side wall of said valve.

Regarding the anti-theft device described here, instantaneous interruption of the fuel supply has significant advantages, especially for diesel engines. Furthermore, this is a feature that existing anti-theft devices do not have.

Some conventional diesel engines have the disadvantage of having to draw in and drain air every time the engine is stopped. In such devices, engine operation cannot be immediately reset until the fuel is exhausted. This can be avoided using a device of my invention that activates instantly by pressing the emergency reset button.

The installation will generally have to be modified depending on the vehicle, but simply the secondary relay is "bridged" between the two legs. One leg allows current to be input, and the other leg is directly connected to valves that are connected in parallel for operation at various locations on the vehicle.

The emergency reset device is installed between the oil/temperature valves and other optional valves, and is also connected to the secondary relay.

The connector base of the primary relay is connected to the ground cable. Another cable is connected from said cable to interconnect the current input to the connector base via the next connection from the connector base. After the two connections are made, the current is sent to the indicator bulb, light, alarm or buzzer. The battery coil current to the device is cut off when the primary relay is removed, for example when the vehicle is inactive or parked. Finally, install a single outlet to the current intake coil on the connector base opposite the first connection.

In a more simplified embodiment of the improved anti-theft device, which also protects the vehicle from possible connecting rod and Viton jamming, various valves are installed to
Oil pressure or temperature is measured 17 at each part of the vehicle to be protected, such as the transmission, case, differential case or brake system, and is connected in parallel to an emergency switch, and from this emergency switch to a secondary relay. The secondary relay is then connected to the battery on one side and has a bypass to the key used to start the vehicle.

The secondary relay is also connected on the other side to a set of lights, alarms, or buzzers located on the vehicle's instrument panel.

Through this same channel, install another bypass, 2
Next, the relay is connected to the correctly embedded connector base, one of the connections extends from the connector base to the power supply, and the other connections are installed.

The anti-theft device of my invention automatically cuts off the electrical current and fuel supply in the event of engine failure, protecting the vehicle from theft by removing the primary relay from its location, i.e., from the connector base.

In particular, in the present invention, the current or fuel can be reset by pressing the emergency reset button separately without using the vehicle's starter.

Although my invention has been described above only in a few embodiments,
It should be understood by all those skilled in the art that other embodiments and applications are within the spirit and scope of the invention.
