Description

Title : THE MOBILE EMERGENCY LIGHT AUTOACTUATOR

Technical Field

The present invention concerns a type of mobile emergency light auto- actuators, which automatically starts up the emergency light in connection with the emergency light control device of the vehicle when the driver exerts sudden strong force on the brake.

Background Art

There are many types of mobile emergency light actuators that have been suggested in order to aid the driver in an emergency case to better notify the driver(s) of the following car(s) of the emergency situation by automatically actuating the emergency light when needed.

South Korean Public Utility Model No. 89-10595, "Emergency Light Actuator in Connection with the Sudden Braking of the Automobiles", suggests an automatic actuator of automobile emergency light that can turn the emergency light on and off briefly by exerting force on the switch using the inertial force of the pistol whose movement has been induced by sudden braking.

South Korean Public Utility Model No. 1990-0002995, "Actuator of Sudden Start-up and Emergency Light of the Automobile", suggests an emergency light auto-actuator with dual switches in the bottom connected to the brake switch and a supporting frame equipped with a screw hole and safety pins in the upper part. On the supporting frame are fixed loads and cylindrical projecting part whose upper part is fixed onto the load so that it can move in slippery and rotary directions within the supporting frame. At the lower end of the supporting frame are a weight with a taper groove that can actuate the said dual switches and a compression spring fixed by safety pins. One end of the compression spring is facing one end of the projecting part and the other end is projecting out of the supporting frame to meet with a fixed lever in the form of

South Korean Public Utility Model No. 10-2004-0053937, "Emergency Light Auto-Actuator for Sudden Braking of the Automobile" suggested an emergency light auto-actuator for automobiles equipped with a brake switch connected to the brake pedal, the speed sensor, and an emergency light. The proposed device consisted of a control unit that determines whether there has been sudden deceleration by analyzing the numerical values sent by the speed sensor and the brake switch, and a switch-less automobile emergency light auto-actuator that actuates the emergency light as ordered by the control unit.

Disclosure of Invention

As discussed so far, although there have been many emergency light auto-actuators suggested for cars, all these emergency light auto-actuators have too complicated a structure and theoretical background for practical applications. In other words, the existing forms of emergency light auto- actuators suggested either aren't realistic enough or are incredibly difficult to produce and install due to their structural complications. In addition, an emergency light auto-actuator should be controlled with as much as accuracy possible in connection with the brake device. The suggested auto-actuators, however, are not expected to perform their intended functions with accuracy.

The present invention has been developed to compensate such problems with the existing types of emergency light auto-actuators. Its relatively easier structure makes production and installation of the device much easier. It also provides solution to the problem concerned with the accuracy of the device functions in connection with the brake.

Effects of the Inventions

The emergency light auto-actuator of the present invention does not require the driver to search for the actuator switch in hurry or be stricken with fear in an emergency case. The automatic actuator functions in sudden braking with much more accuracy than the manual actuator. Its simple and easy structure makes it possible for almost anyone to install it to his car. Its simple and straight controlling structure also increases the consumer trust and confidence in the device.

Best Modes of Carrying Out the Invention In order to achieve the objectives discussed earlier, the present invention consists of an emergency light auto-actuator with a sliding hole (30); a frame (20) that forms a holding space (40) on one side of the said sliding hole (30); a sliding bar (50) projected toward the front by a spring (70) supported by the said sliding hole (30); a switch (90) installed in the said holding space (40) that sends out connecting signals when the sensor bar (92), installed on the said sliding hole (30), leads the said sliding bar (50) to move backward in a designated distance; and a delay circuit (100) connected to the said switch (90), which causes the emergency light to turn on for a designated period of time by activating the emergency light control circuit (200) when the connecting signals from the said switch (90) is received.

The mobile emergency light auto-actuator of the present invention can be further equipped with a tip (80) connected to the said sliding bar (50) so that its projectile length can be adjusted. Here, the said sliding bar (50) of the emergency light auto-actuator should be equipped with an internal screw part (62) formed toward the inside of the bar from the front, and the said tip (80) should be connected to the screw part (62) by means of screws.

In this emergency light auto-actuator, the said sliding hole (30) is formed in penetration along the said frame (20), and the said sliding bar (50) is composed of Sliding Part I (52) and Sliding Part Il (52) connected by a solo motorcycle (56). Sliding Part Il (54) should be located on the initial position of the sensor bar (92) of the said switch (90). Once Sliding Part I (52) reaches the position of the said sensor bar (92), the sensor bar (92) may be actuated. Here, back of the sliding bar (50) should be a screw part (58), which may be fixed by a nut (59) outside the said frame (20).

The present invention provides a automobile emergency light auto- actuator that can instantly turn the emergency light on for a set period of time in times of emergency crises. The said device is characterized by having a structure {formed by a frame (20) and a sliding bar (50) or a tip (80)} that adjusts the braking depth depending on the type of automobiles and drivers; another structure {formed by a frame (20), a sliding bar (50), and a switch (90)} that recognizes the sudden braking of the automobile; and the final structure {formed by a delay circuit (90)} that activates the emergency light of the car by recognizing the signals from the preceding structure.

The emergency light auto-actuator has a structure that can be freely adjusted and installed in almost all spatial structures of different cars. When faced with an emergency or imminent danger, the driver usually exerts much stronger force on the brake than usual. The emergency light auto-actuator of the present invention was designed to turn and maintain the emergency light on (approximately for 7 seconds or any time range deemed fit by the driver) when the driver exerts force on the brake that is greater than the preset range. The light automatically notifies the following car(s) of the imminent danger, contributing to safe driving and prevention of automobile accidents.

The examples of appropriate usage of the present invention are discussed in the following paragraphs with references to Figures 1 and 8. The components in Figures 1 and 8 that perform the same functions as ones discussed in the following paragraphs will accompany the identical reference numbers. Since the components and functions of the emergency light auto- actuator are known to professionals working in the field, they are omitted: only the components that are directly related to the present invention are shown in the Figures. Mechanical means used to connect parts, such as bolts, nuts, holes, screw holes, as well as welding are omitted from the drawings without separate descriptions. In terms of expressions used in the figures, some components may have significantly different sizes and proportions from one figure to another. Such differences, however, can easily be understood by professionals working in the field: they will not accompany separate descriptions or explanations accordingly.

Figure 1 and Figure 2 are sectional views that illustrate the mobile emergency light auto-actuators and conditions of its usage under right circumstances. Figure 4 is a slanted deal drawing that illustrates the conditions of the emergency light auto-actuator when used under right circumstances.

Figures 1 , 2, and 4 show that the emergency light auto-actuator (10) of the present invention, composed of a frame (20), a sliding bar (50), a switch (90), and a delay circuit (90), should turn and maintain the emergency light for a designated period of time when the force exerted upon the brake (210, see Figure 5) is greater than the preset or usual range.

The frame (20) contains a sliding hole (30), on one side of which is a holding space (40). The frame can be made up of various materials, and the present figures show a plastic frame originally formed in two parts and mechanically connected to form the sliding hole (30) and the holding space (40). The sliding bar (50) is installed on the sliding hole (30) in a way that it can move back and forth. It is projected toward the front by the spring (70) anchored to the sliding hole (#0). The front (32) of the sliding hole (30) should be greater than the spring (70) in terms of the external diameter. The rear (34) of the sliding hole (30) should be smaller than the spring (70) in terms of the external diameter so that it can anchor the spring (70) on the one side and form a head (60) on the foregoing part of the sliding bar (50) to support the other side.

Although the sliding hole (30) that anchors the sliding bar (50) and moves back and forth in it can be molded in various shapes, the present figures feature a sliding hole (30) that penetrates along the frame (20) and a sliding bar (50) composed of Sliding Part I (52) and Sliding Part Il (54) connected in one by a solo motorcycle (56). The emergency light auto-actuator of the present invention sought to simplify its structure as much as possible by making the sliding bar (50) move back and forth in the sliding hole (30) that penetrates the frame (20). By doing so, the sliding bar (50) can have a greater range of force than the range of usual force exerted upon the brake (210) so that it can move behind the sliding hole (30) when the force exerted is greater than the usual or preset range. Such a shape and mode of using the sliding hole and bar can be modified in various ways. For instance, by making a sliding hole (30) inside the frame (20) unlike the one featured in the present figures, the sliding bar (50) may still move back and forth.

The sliding bar (50) should have its projectile length determined by having behind it a screw part (58), which is fixed outside the frame (20) by a nut. Adjustability of the projectile length enables the driver to adjust the brake settings depending on the structure and model of his car. In the present figures, a tip (80) whose projectile length can be adjusted was added to the sliding bar (50). Although the tip (80) may also have various structures and ways of installation, the one featured in the present figures is connected to the internal screw part (62) formed inside the sliding bar (50). The tip (80) here should be more effectively secured by a nut (88).

In the holding space (40) formed in the lower part of the sliding hole (30) should be a switch (90) and a delay circuit (100). The switch (90) sends out a connecting signal when the sensor bar (92) is installed to project into the sliding hole (30), thereby causing the sliding bar (50) to move back in a designated distance. Here, the switch (90) should structurally be connected to the sliding bar (50) for its activation. Namely, Sliding Part Il should be located on the initial position of the sensor bar (92) of the switch (90), and Sliding Part I should activate the sensor bar (92) when it reaches the position previously occupied by the sensor bar (92). The switch (90) can come in various forms and types. The one featured in the present figures is the type with a pushable sensor bar (92). A switch with a different type of the sensor bar (92) may still work.

In the holding space (40) should also be a delay circuit (100). The delay circuit (100) is connected to the emergency light control circuit (200) as well as the switch (90) so that it can pass the connecting signals from the switch (90) to the emergency light control circuit (200), which will activate the emergency light for a set period of time in turn.

Figure 3 is a circuit diagram that shows one example of the delay circuit used in the emergency light auto-actuator illustrated in Figures 1 and 2.

Figures 1 and 3 show that the emergency light auto-actuator (10) can turn and maintain the light on for a period of time, and automatically turn off, as dictated by the delay circuit (100). The delay circuit (100), connected on the same circuit board as the switch (90), is installed inside the holding space (40) of the frame (20). The delay circuit (100) acts to maintain the activated (time) range of the light even if the braking was really sudden and brief. The delay circuit (100), connected to the emergency light control circuit (200) in parallel, enables the emergency light to turn on and off automatically in replacement of a manual switch. Once the switch (90) sends off a connecting signal, the positive (+) electric charges are built up in the electrolysis condenser (101) via the switch (90), and the resulting resistance (102) controls the transistor (103). Once the electronic contactor (104) connected to the transistor (103) is activated, the emergency light turns on and off automatically, thanks to the point of contact (105) of the contactor (104) connected to the light in a parallel circuit. The time throughout which the light remains on is determined by the electrolysis condenser (101) and the resistance (102).

Figures 5 and 6 are drawings that show how to connect the emergency light auto-actuator directly to the brake. Figures 7 and 8 are drawings that show how to fix the emergency light auto-actuator onto the body.

Figures 5 and 8 show that the emergency light auto-actuator (10) can easily be installed on the brake (210) and/or the body of the car. In the usage example featured in these figures, the distance in which the tip (80) can move can be adjusted by the movement of the brake (210) depending on the automobile types and models. The nut (88) secures the set tip (80), and the spring (70) restores the sliding bar (50) back to its original position when the brake (210) comes back to its original position. The emergency light auto-actuator (10) featured in the Figures 5 and 6 may be fixed on one side of the frame (20) using a bracket (110). On the other hand, as shown in Figures 7 and 8, the bracket (120) can be fixed onto one side of the frame (20) and the bracket (120) itself can be fixed onto the car.

The examples of appropriate usage of the present invention have been discussed so far with references to the figures enclosed. These, however, are merely 'examples', and modifications in applications of the device can still be attempted as long as they do not completely abandon the original concept and ideal of the present invention.
