Abstract

The invention relates to a measurement device, known as FOPRECE, based on rear-view mirrors or a remote control system, for use when it is difficult to determine precisely the proximity of approaching objects. According to the invention, the rear-view mirror shows a circle or ellipse formed by laser-beam-generated spaced-out points. In addition, a central point indicates the lineament of the body fitted with the device. The invention includes laser-beam-emitting elements which concentrate the peripheral beams at a point on the axis formed by the central beam. The peripheral beams form cones that produce the above-mentioned circle. As the inventive device approaches a vehicle, the projected cone (after the vertex) reduces to form an ever-decreasing circle or ellipse. The surface on which the beams are projected enables the circle to be clearly seen, said circle shrinking until it becomes a point representing the minimum distance. Said point is the limit indicating that the driver should stop approaching the object. When installed in a vehicle, the device is installed at the ends of the rear bumper, namely one on the left and one on the right. The inventive accessory can be used to park any vehicle without any mishaps. The vehicle is manoeuvred with less effort than without the device. The device informs the driver of his/her distance from an object with which he/she might collide. The learner driver always feels tense and makes numerous errors, but the FOPRECE enables him/her to remain calm and drive more safely.

Description

"NEIGHBORHOOD PRECISION FOCUSES" summarized (FOPRECE) The technology sector to which this invention applies is Mechanics in the Field of Optics. The International Patent Classification: F21L, F16B 1/100.

BACKGROUND

So far, there is no known device that is used to specify the distance of a vehicle to a fixed or moving object. Old cars used a spring to know when a vehicle was near the pipe or near an object. As you can see this attachment is not accurate and the noise it produces was also not convincing since if there were external noise it would not be heard when the spring is making contact with something. The rear lights do not serve to quantify the proximity of the vehicle with an object that approaches on the back side. This is because vehicle bulbs produce scattering light.

The way drivers park vehicles is through rearview mirrors. The FOPRECE can not only be used in cars, but also in floodgates, trains, airplanes, gates, etc.

The FOPRECE is an artifact that produces a concentration of light aces that are convenient for laser beams with certain characteristics. Each ray is independent and with variable movement. The rays are installed in a circle and move at an angle less than 90 ° with respect to the plane of the circle and convergent with the axis of the circle. Consequently, these rays are neither more nor less than the generatrices of the incident cone and the divergent cone. That is, they form two light cones joined by their same vertex. The FOPRECE also produces a laser beam perpendicular to the surface of the circle and concentric to it, constituting the axis of the cones. This axis is important because it allows the operator or the driver to observe through the mirrors the guidelines of the moving vehicle or body that i . that the FOPRECE has adapted and that it can be a vehicle. What the driver or operator sees on the surface of the object to which he has to approach is a circle formed by points and he will also observe a point in the center. With these impressions the driver or operator can measure the distance to the object a priori to avoid a collision.

Although many drivers measure in the eye of experience, not everyone does so well. A person after having ingested liquor or some medication is not able to solve a parking operation between vehicles or objects.

From the above it is inferred that, the reason for FOPRECE is to anticipate shocks due to overconfidence. DEVELOPING:

The figures shown are eloquent in their own right since any person showering on the subject can immediately grasp the idea. This means that a person who always parks his vehicle backwards, can imagine what the attached figures mean.

This instrument or tool (FOPRECE) has the advantage for operators or drivers to be sure of the minimum distance to which they can approach the object that approaches them.

The laser beam has the advantage of concentrating light and reflecting it over long distances without varying its size (section diameter) and intensity. In normal driving to park a very wide distance can be 20 meters. This means that the human eye can see the laser marks at that distance that is even very exaggerated.

The FOPRECE has a mechanism capable of varying the position of the vertex of the cones by means of a conductive cable installed in the vehicle. In reality, this distance must always be fixed, but if the owner of the vehicle adds equipment to the rear, this operation must be done.

The goal with this attachment that can be installed in a vehicle, gate, plane, helicopter, boat, judicial investigation vehicle with scale in mirrors, moving bodies, etc., is to avoid collision with great precision. JLOS autom vi is ami iares e cam ios senc os, automatic oeoe traction uses two rearview mirrors. For this reason, taking advantage of these elements, it will not be necessary for the driver to have to turn his head back to park. The reason is that if you have something that indicates how the vehicle is approaching the still object, it is not necessary to turn your head. The advantage of this is that if it rains or it snows it will not be necessary to remove the head.

Generalities:

The driver of a vehicle uses the FOPRECE to know its position with respect to the objects that surround it. In some cases, the FOPRECE may be installed both in front and behind the vehicle; But, the normal thing is that the main problem is on the back side of the car and not so much ahead where the driver has more panoramic.

Another example is the use in an airplane to give the pilot confidence to know how far the landing gear is from the ground.

Another example is the use in trailers or gates that must leave a space for people to pass. Similarly for boats or heavy bodies in motion.

Advantages of FOPRECE. It is useful to avoid collisions and to park more easily. This facility is acquired in the same way when any person uses a tool and eventually acquires skill.

Disadvantages of FOPRECE This attachment can be installed on the top of the kicker (BUMPER for vehicle) and in very special cases inside it and for this you will have to make a hole to let the ace of light out. In other words, it must be installed independently of the taillights. To what extent is this disadvantage profitable? Only the manufacturer can quantify it. Description of the Figures

Fig. (1/5) represents the scheme of the formation of the cones due to the laser beams that are concentrated at a distance (1/5) (4) from its emitter (1 / S) (I) which is a set of foci that throw their rays at that point of the axis (l / 5) (2).

The object (1/5) (3) that could be in relative motion with respect to the mobile (1/5) (1) but, in most cases it is a fixed object.

The front view of the FOPRECE shows a number of emitting bulbs according to the number that the manufacturer considers convenient. The emitters including the focus of the laser beam axis (l / 5) (5) are what allow to reflect its light in the body (l / 5) (3).

All these bulbs are installed in a plane (l / 5) (6) perpendicular to it. The rays move through an individual mechanism of each focus as will be seen later. Figure (2/5)

This figure shows a level of more detail where the bulbs contain the elements: laser emitter (2/5) (l), its pivot (2/5) (3) and its position mechanism (2/5) (2) which is moved by a cogwheel (rack) (2/5) (7) that makes contact with the respective pinions of each of the bulbs, threaded inside to make the screw move endlessly (2/5) (2) . Each pinion is fixed in the axial direction by means of a box referred to later in the cut (2 / S) (A-A). The cut (2 / S) (B-B) will show the back of the wheel plane (2/5) (7) that is moved by a motor (2/5) (9). In the central axis is located the central focus (2/5) (6) that emits the central ray (2/5) (5) that joins at the apex of the cones.

The anchor housing for moving the transmitter (2/5) (8) functions as a universal joint fixed to the transmitter with the freedom to move that allows the pivot joint (2 / 5X3). Figure (3/5)

This figure shows the cuts and the parts that interact in the movement of the lights. The cut (3/5) (B-B) shows the foci from the back to a summary number of six (3/5) (l). The wheel (3/5) (2) has a rack (3/5) (6) that moves the pinion in a rotating direction without moving it axially due to the limitation of its enclosure that is lubricated inside. The motor (3/5) (5) moves the wheel (3/5) (6) so that all transmitters simultaneously move at the same time.

The anchor enclosure (3/5) (2 / 5-8) shows how the transmitter pushes and pulls the pifion (3/5) (7). The axle (3/5) (4) maintains the position perpendicular to the plane of the wheel and at the same time sets the emitter of the focus (3/5) (8) in that same position. Figure, (4 / S)

This figure shows the implementation of the FOPRECE; the location of the driver in the vehicle without turning the head (4/5) (3), look at the circles or in some cases ellipses, for the practical it does not matter and the central reflex matters. As the vehicle goes backwards (the FOPRECE is only activated in the reverse gear), it starts operating the FOPRECE when necessary, sees the object that can be a wall with the points forming the aforementioned and concentrates on them but seeing also forward. The side views (4/5) (l) and (4/5) (2) will become familiar almost from the first moments if the driver has at least one year of experience. With practice, the driver will specify the distances to the object (4/5) (4). The problems of parking between two vehicles with difficulty and the pain that others were seeing it were over. Figure (5/5)

This figure indicates one of the positions where the FOPRECE (5/5) (l) will be selected. The scheme says it all and to anyone it can come to mind clear is not so accurately but if something related to artificial light coming from the vehicle.

FOPRECE is also used for other uses as stated at the beginning but presumably the greatest commercial use could be in automobiles. An important detail is that the rays (5/5) (2) let you know the proximity of moving objects that approach the vehicle (5/5) (3).

Another detail is that the driver can vary the vertex of the cones and in a dial near the "dashboard" get the exact distance to it. The FOPRECE is a solution to the precision problem to better park in any parking lot. A trailer of a heavy vehicle can be easily parked easily with this device.

It is important to understand that FOPRECE improves the way you drive a vehicle in any city without problems or inconvenience with others. One of the details that could be discussed is the mechanism to move the laser emitters. A mechanism similar to the conventional diaphragm of a camera or other similar mechanism could be used. This does not destroy the main idea that it is using reflex marks of the lasers that are observed on the surface of the object to which the vehicle that has the FOPRECE approaches.
