ITRM950738A1 - MOTOR VEHICLE IMPACT PROTECTOR AND SIGNALER - Google Patents

Abstract

The device comes into operation due to the crushing, due to the impact with external bodies, of the cap (A) which activates the switches or sensors (3) which close the electrical supply circuit of the acoustic or optical warning devices (6) and / or the acoustic-pneumatic ones (8) activated by the passage of air due to the crushing and the return to the rest position of the volume (1) contained in the cap (A).

Description

Description of the industrial invention entitled:

IMPACT PROTECTOR AND SIGNALER FOR MOTOR VEHICLES

SUMMARY

The invention consists of a protection device to be installed by means of a suitable attachment base in the protruding parts of the car (with particular reference to the bumpers) in order to signal to the driver the contact with other vehicles and various obstacles, and to avoid damage to the vehicle. own car and other things, especially in uncomfortable parking maneuvers and in those made difficult due to adverse weather conditions (visibility, etc.).

The invention is made of plastic material, rubbery and / or spongy and / or with volumes of air, which make it shock absorbent and effective against the shocks caused or suffered.

It essentially consists of an external casing, of various shapes and sizes or already inserted in the structure of the bumper itself; but illustrated here for reasons of descriptive simplicity in semispherical form, containing one or more electric switches of the pushbutton type, or one or more contact sensors that send the impact signals through special electric circuits to optical and / or acoustic reproducers, to the inside or outside the passenger compartment of the vehicle.

Alternatively, or in addition to the switches or sensors, acoustic signaling devices operated pneumatically and directly by the deformation of the device can be installed.

TEXT OF THE DESCRIPTION

In the past there were metal elements called "ROSTRI" often bearing hard rubber finishes that were applied on the front and rear bumpers in order to protect the bodywork.

In practice, the effects resulting from the various impacts also fatally impacted the attachments of the bumpers to the bodywork as they were rigidly connected to it.

The current technique has created plastic bumpers capable of absorbing small impacts and in any case not able to avoid small damage to themselves, paint scratches, etc.

The device in question can be applied to any type of motor vehicle and in any number of examples, depending on the parts to be protected. It aims to increase safety and protection in shocks caused or suffered and works by:

A) Additional shock absorber as it firstly combines its own absorption capacity with that of the supplied bumpers, making the shock absorbing action more effective and thus reducing damage to things and people.

B) Indicator for the driver, in uncomfortable parking maneuvers, in case of contact with obstacles.

The possibility of being "warned" of having come into contact with an obstacle allows the driver to be able to maneuver more quickly and use the maximum amount of space available in order to be more certain not to cause or suffer damage.

The invention represented in the drawing in a purely demonstrative but not definitive form, has a hemispherical shell (A) of rubbery and / or spongy plastic shock-absorbing material and / or with volumes of air specially designed to absorb even substantial shocks, and return to its original configuration to allow the repetition of its functions. It is capable of resisting wear and atomospheric agents. It also has a base (4) that can be adapted to the surface of the body, bumpers etc.

The device in question can also assume an extended form as a band which, if desired, protects the bumpers in part or in their entire extension - the same applies to the sides. Inside it has a housing (1) which defines a pneumatic volume containing a switch (3) or sensor connected to an electrical circuit (9) which includes the indicators (6), inactive in the rest position. The contacts of the switch (3), touching each other following the crushing of the body (A) due to the impact, allow the passage of the electric current which activates the electro-acoustic horns (6). The aforementioned warning devices (6) may be those already supplied with the vehicle. (see arrows, warning lights, position lights, buzzers, etc.) located both inside and outside the passenger compartment, but others of various types with specific functions can be applied.

The device can also contain, alternatively or in addition, one or more acoustic-pneumatic alarms (8) inserted in the support (7). The pneumatic horn (8) for reasons of demonstrative simplicity has been shown in the drawing on the other side of the housing (1) on a support like a cap (7) operating with single or double effect. Said warning device (8) housed in the cap (7) comes into operation due to the inlet and outlet of the air passing through the orifice (5) as a consequence of the crushing of the casing (A) and therefore of the pneumatic volume. (1) and its return to rest position.

Claims (2)

CLAIMS 1) Protective device and collision warning device, for motor vehicles, characterized by a body (A) of various shapes and sizes (hemispherical, prismatic or more modular elements, etc.) equipped with one or more attachment bases (4) to the parts of the bodywork (bumper, etc.) or already inserted in the structure of the bumper, consisting of plastic, rubbery, spongy material and / or with volumes of air that make it shock-absorbing, containing one or more housing compartments (1) - (depending of its functions), in which one or more switches or sensors (3) connected to the external circuit (9) that powers and activates the alarms (6) are inserted following the crushing of the body (A) due to the impact. 2) Shock protector and alarm device for motor vehicles according to the preceding claim, characterized in that as an alternative or in addition to the switches (3) connected to the electrical circuit (9) supplying the electrical signals (6) it can contain one or more acoustic alarms -pneumatic tires (8) with single or double effect which come into operation due to the passage of air through the orifice (5) as a consequence of the crushing of the casing (A) and therefore of the pneumatic volume (1) and its return in rest position. Impact protection and warning device for motor vehicles characterized by what is described and illustrated substantially by way of example and for the specified purposes.
