Definitions
- the present invention refers to the sector of protective glasses that are used as a complement to protective helmets and particularly to protective glasses that are used as a complement to motocross helmets.
- motocross helmets are characterized in that they include an elongated visor to protect the eyes from the sun's rays and a prominent windshield to protect the mouth and jaw from the impact of mud and stones that are thrown from the rear wheel of other motorcycles. pilots and also in the event of a fall.
- the visor is located above the facial opening of the helmet shell, and the montonera covers the facial opening of the helmet shell in its lower half, from the height of the cheeks to the chin, being in front of the face of the helmet.
- the goggles for protective helmets in general and for motocross helmets in particular known in the state of the art comprise a frame and a single panoramic lens, called a screen.
- the mount consists of a front or frame and an elastic band as the most commonly used means of fastening to the helmet, although there are also other less used fastening methods.
- Goggles with elastic headbands have been in use for decades, as revealed by Leonard Peter Frieder's patent GB 820,745. Although they were conceived to be used as a complement to protective helmets, there are now sports in which goggles are worn directly on the head, without a protective helmet, for example, in skiing or snowboarding.
- the screen that is inserted in the front of the frame protects the eyes, the nasal septum and the entire ocular cavity from the impact of mud, stones, water, air, dust and other external elements present in motocross circuits; while the elastic band allows the protective goggles to be held on the pilot's face due to the tension produced by placing them around the shell or outer shell of the helmet.
- the elastic band also acts as a means to hold the goggles when they are placed on the helmet to be used and also to remove them and even to hang them from the handlebar of the motorcycle, as it allows them to be removed from the helmet's facial opening by grasping them by the section of band elastic farthest from said opening and pulling forwards above the shell of the protective helmet;
- the pilot pulls the ends of the elastic band that are inserted into the sides of the goggles with both hands, tightening them to be able to guide the front towards the face opening of the protective helmet.
- the goggles are worn directly on the head, they are not removed by pulling on the elastic band as the wearer's hair is pulled, which is annoying.
- the front of the goggles is pulled and here comes the inconvenience that in order to pull the front of the goggles you have to grab it from the edges, where the ventilation holes are located which are covered by a thin layer of foam that acts as a filter, and which can be damaged.
- protective glasses whose front includes means for grasping or pulling the front without touching the screen, the rest of the parts that make up the front or even the elastic band.
- the elastic band used in protective glasses in general it has been improved over time, for example, by placing longitudinal silicone inserts in the elastic band that, when in contact with the surface of the shell, produce an anti-slip effect, thus preventing the elastic band of the glasses from shifting.
- the first drawback is that the elastic band makes it difficult to put the goggles on the face. This is because the sizable elastic band is attached to the farthest ends of the goggle front, so the pilot must move it out of the way so it doesn't get caught between his face and the goggle itself, specifically in the inside face of the frame front. To prevent this from happening, fitting the goggles into the face opening of a hard hat requires the use of both hands, one to hold the front of the goggles over the face while the other pulls the elastic band down. on top of the protective helmet, stretching strongly so that the band manages to surround the entire shell of the helmet.
- the protective glasses have to be taken from the upper and lower edges of the front, where the ventilation holes are located that prevent the glasses from fogging up and that are covered by a thin layer of breathable foam that acts as a filter, so the force used to pull on the front to stretch the elastic band enough to encircle the shell can damage those vents and cause the goggles to fog up during use.
- the foam that rests on the pilot's face is also located on the lower edge of the front, which can also be dirty or damaged.
- the placement of the elastic band on the shell of the helmet becomes more difficult in motocross helmets since they have an elongated portion of the visor to protect themselves from the sun's rays.
- Another method to reduce the impact of mud on the screens of protective glasses is to add an extension to the visor, which is usually transparent so as not to reduce visibility, which makes it more difficult to remove and put on protective glasses.
- the conventional visor already supposes in itself an obstacle to place the elastic band on the shell of the helmet.
- the second inconvenience is that, despite using both hands, the goggles are often not accurately adjusted, and can be slightly tilted on the pilot's face, which is clearly uncomfortable because, when tilted, they press on the eye socket or the nasal septum. in one of its parts, which in turn poses a danger due to the partial loss of vision that this causes. For this reason, the placement of protective glasses requires in any case the use of both hands.
- the third drawback is the difficulty that the pilot has in removing the elastic band from the shell of the helmet when he suffers a strong fall, which usually entails a loss of breathing capacity due to the impact with the ground. For this reason, it is common to see in cases of severe falls without loss of consciousness how the first thing the pilot does is try to remove the goggles to try to breathe air. However, sometimes the elastic band moves down, getting caught between the nape of the neck and the shell, and the pilot has trouble locating it with his hands. In addition, in the most severe falls with the risk of paralysis, the head and neck should not be moved, so it is possible that the elastic band has been left in a position that makes removal difficult. of goggles.
- the fourth drawback is that, when the goggles are not in use, the rider wears them hanging from the forearm or one of the handlebar grips; which causes the glasses to remain in a horizontal position to the ground as if they were a bag, which causes the dust to settle on the inside of the protective glasses dirtying the screen, or that it remains at the height of the user's knee pilot, being able to hit it with it and scratch the screen. It is also common to see users wearing goggles inside the helmet when they are holding the helmet by hand because they have finished skiing or riding a bmx, for example. In those cases, there is a risk that the goggles could fall to the ground without realizing it and end up losing the goggles.
- the fifth drawback has to do with the durability of these elastic bands, because the elastomers with which they are made lose their properties with use, due to exposure to sun and rain.
- the elastic band takes up a lot of space and does not fold up, when not in use the goggles are stored inside the helmet together with the gloves, and the textile material of the elastic band deteriorates by snagging on the Glove closure system, mostly hook and loop.
- the sixth drawback is of an aesthetic nature, since the elastic band is continually exposed to dirt stains since the textile fiber absorbs grease and dirt stains, and cannot be separated from the front to wash it.
- helmets are usually decorated with graphics that represent an aesthetic element of high value for the consumer, which are covered by a dirty and damaged elastic band.
- the helmet shell is a showcase for sponsors, so both consumers and professional athletes are forced to partially cover the shell with the elastic band of the glasses.
- the seventh inconvenience is hygiene, since to put on the goggles the pilot has to grab the front of the goggles from the inside to avoid scratching the screen, and in doing so touches the foams that come into contact with the face and those that act as a filter in the side ventilation openings to prevent the screen from fogging up.
- a final inconvenience is that associated with the conservation of the environment, since the elastic bands are made up of a mixture of textile fiber with plastic fabric, so they are not easily recycled, and as with all waste that has a rubber that closes its two ends over a solid body, it can trap animals if the elastic band goggles end up in a landfill at the end of its useful life.
- Protective glasses are known in the art that dispense with the traditional elastic band as a means of coupling to protective helmets and replace it with other systems.
- Patent US9072331 B2 shows a system that uses two portions of elastic band with two fastening devices at their ends that are hooked to two base portions that adhere to the shell of the helmet, one fixed and the other by means of a hook and loop system. loop in such a way that the goggles are always attached to one side, hanging from the shell of the protective helmet, which allow the attachment of goggles on helmets and their subsequent release with one hand.
- This system is designed for enduro practitioners, for times when the rider has to take off his glasses because he has stopped to examine the difficulty of a section of the journey and thus prevent them from fogging up; however, this system has several drawbacks since, firstly, the anchoring system is exposed to breakage due to impact of the helmet given its location on the shell; second, the pilot has to be familiar with guessing the exact location of the hook and loop mount; thirdly, this system requires the pilot to remove the helmet to completely separate the goggles from the helmet, for example when it is necessary to clean the inside of the screen because it makes vision difficult; and a final drawback is imposed by the hook and loop system used, since with use it loses qualities and exposure to water and mud also reduces its holding capacity.
- Patent US6845548B1 shows a fixing system for protective glasses by means of a buckle that is hooked to a portion that is placed on the outer shell of the protective helmet.
- the use of mechanical fastening means has the drawback that they are susceptible to blockage, either due to traces of dirt that settle in the openings where they are attached, or due to breakage of the mechanisms due to an impact in the event of a fall, or by oxidation of the retention springs.
- the last drawback of this system is that the goggles with these fixing systems are not designed to be attached to the handlebar of the motorcycle when they are not in use or to any other element that is not the protection helmet itself, which they complement.
- Magnets have been used for a long time as a means of fixing and rapid release of objects on ferromagnetic surfaces thanks to its magnetism, considered as the ability to attract the opposite poles of other magnets or other ferromagnetic bodies.
- the use of magnets is also known in the state of the art, for example in eyeglasses, to hold different sections of the frame together, which facilitates disassembly and assembly in a new configuration, with auxiliary frames, lenses or the like.
- US6168273B11 patent teaches the use of magnets in eyeglass frames to temporarily fix the eyeglasses in a support article having magnetic means.
- patent US20140043682A1 shows the use of magnets in protective glasses as a means of fastening and quick release of the screen from the front of the frame, for lens replacement.
- Patent EP3284360 claims a pair of magnets fixed to a pair of elastic rubber cylinders through which the temples of universal frame glasses such as those used for cycling are placed, so that the magnets are fixed to the temples. and with this the glasses can be fixed to any ferromagnetic surface that in this case is located on the shell of the bicycle helmet or the handlebar of the bicycle, all this to prevent the glasses from scratching while the glasses are not in use.
- the problem presented by this invention is discomfort, since it is proposed for glasses with a universal frame with rods to which the magnets are placed, which is uncomfortable for the pilot, as well as being visibly unsightly. Indeed, universal frame glasses can only be used with specific cycling helmets where the ears are not covered.
- Patent EP2305053B1 shows the use of magnets to fix frameless glasses to a ski helmet, by means of two permanent magnets placed in the shell of the helmet at the height of the temples that connect with the magnets fixed at the two ends of cords attached to the goggles as a frame, which allows the The goggle hangs from one of the cords attached to one end of the helmet surface when not in use, preventing the rider from fogging up, while it can be easily donned with one hand.
- this invention presents two obvious problems: the first one is that the fixing means located on the outer surface of the helmet are exposed to breakage due to impacts due to falls, and furthermore, the goggles can be loosened and lost; and the second of them is that to put on the glasses you have to grab the screen, which gets dirty and exposes you to scratches.
- This invention also refers to the use of magnets with conical shapes as a way to center the glasses, however, this presents an obvious problem because a base with a conical shape becomes a cavity that allows unwanted elements such as mud residues to get into the glasses. located inside the magnet and reduce its magnetic properties, while it is difficult to clean if the appropriate means are not available.
- protective helmets for motorcycling, bmx, skiing or snowboarding are generally composed first of all by an external lining called the shell, generally obtained from synthetic fibers such as aramid, carbon or glass, which is the that receives, supports and distributes the impact; secondly, by an internal lining, called the inner shell, generally made of expanded polystyrene foam (EPS) that protects the head and is shaped like a cap;
- EPS expanded polystyrene foam
- the edges of the expanded polystyrene foam that protrude through the face opening of the helmet are covered by a molded plastic sheet that acts as a protector and as a trim or termination of the edges of the EPS, although some models of helmets also use it as a diffuser of wind towards the interior of the helmet.
- this type of helmet is made up of an inner padding with a lining, whose main function is to properly adjust the helmet to the head so that its use is comfortable.
- the inner padding was a fixed part of the helmet and could not be removed, but today practically all helmets have removable and washable inner padding.
- This is achieved thanks to a plastic structure semi-rigid in the form of a plate that is fixed on the surface of the inner shell by means of different systems that allow its release, and several elongated plates of polyurethane foam or similar of different widths covered with a washable lining that cover the head like a cap, leaving separations between them to favor ventilation.
- inclement weather and wear and tear make it inevitable that the inside of the helmet will be damaged and will no longer be as comfortable as it was at the beginning, and most importantly, that it will no longer be safe.
- FIG. 1 Another element of the internal padding independent of the previous one are a pair of right and left inner cheek pads for the pilot.
- These inner cheek pads are formed with plate-shaped bodies generally made of polyurethane foam or similar with different densities cut in three dimensions, and are attached to a semi-rigid plastic structure with the same plate shape that adheres to the surface. inside the shell by different means that allows its release to be able to wash the dirt accumulated by use or even to facilitate the removal of the helmet in the event of an accident.
- patent US10238164B2 shows the use of magnets in protective helmets as a fastening and quick release system for the pads that protect both sides of the pilot's jaw in the event of an accident.
- magnetic products of different shapes can be obtained by injecting magnets into different plastics.
- the present invention proposes a protective goggle front assembly and a device for coupling it to the facial opening of protective helmets in general and helmets for the practice of any modality.
- the front of the goggles comprises means for grasping and magnetic fixing means
- the device for coupling it comprises magnetic fixing means and means for fixing or adhering to the inside of the helmet in the opening area face where the pilot's face is placed on which the protective glasses are placed.
- Both the front of protective goggles and the device for coupling it to the facial opening of protective helmets comprise magnetic attachment means composed of a magnetic or magnetizable portion that is detachably or inseparably attached to a base portion, which in the case of the front may be the front itself or any separable part thereof; and that in the case of the device it may be configured as one of those elements that are present inside the protective helmets and in any case outside the surface of the outer shell, for example an expanded polystyrene coating (EPS) , or an independent piece made of light and resistant material that can be adhered to that same area, for example by means of a band of high resistance glue on both sides, so that it is already present in the base portion and can be glued to the inside of the helmet on face unused.
- EPS expanded polystyrene coating
- the characteristics of the proposed invention solve the problems presented by protective goggles for use with a protective helmet that use an elastic band as a fixing means and also the problems presented by protective goggles that use the rest of the fixing devices mentioned for coupling to the facial opening of protective helmets and whose front does not have means to grab.
- the incorporation of magnetic fixing means in the front of goggles and in the proposed device enables the coupling of the front of goggles to the facial opening of protective helmets that do not have magnetic fixing means and incorporate the device, while the The proposed protective goggle front can be attached by itself to any other type of helmet that already incorporates magnetic attachment means arranged correlatively to create a field of magnetic attraction with said front.
- the magnetic fixing means included in the proposed front are releasably or inseparably attached to the internal face thereof, protected from possible impacts, and comprise one or more magnetic or magnetizable portions, preferably flat, and can have any shape, for example rectangular ; They can also be joined to the front by any means known in the art or joined by high-resistance adhesives or by injection of magnets into the plastic of the same base portion, which will preferably be the internal face of the front.
- the magnetic fixing means comprise two magnetic or magnetizable portions located at both lateral ends of the front on its internal face, which are releasably or inseparably joined.
- internal face or “inner face” of the front is meant the part of the front that surrounds the screen and that during use is positioned internally, that is, opposite the outer part of the front that is exposed to the wind, rain, snow or mud, among other elements.
- the elastic band also acts as a means to grip the goggles when they are placed on the helmet for use and also to remove them and even to hang them from the handlebar of the motorcycle, it is necessary to provide means to grip the front of the goggles. that fulfill this same function but without generating the problems described, so that they allow the pilot to pull the front of the goggles forward with enough force to overcome the magnetic attraction of the magnetic attachment means of the coupling device and thus uncouple it from the facial opening of the helmet, or simply to be able to leave them hanging from the handlebar of the motorcycle. This is achieved by an elongation on either side of the front towards the outside, outside the field of view that encompasses the entire screen.
- external face of the front is meant the part of the front which during use is positioned externally, that is, exposed to the outside.
- Said elongation can have any shape that allows the front to be grasped, for example, a curved tongue shape like that of a shoe horn so that there is a free space between the shell of the helmet and the tongue in which the tip of the helmet can be inserted. fingers to free the front of the helmet's face opening.
- the tab may have a hole that gives it a handle shape, like that of a cup, and allows the pilot to grasp the goggle with just one finger in the hole and pulling on the front.
- the hole can be large enough to accommodate a motocross bike handlebar grip for temporary goggle hanging when not in use, also replacing the traditional elastic band as a means to hold the glasses to the handlebar of a motorcycle.
- the diameter of the hole can be adapted according to the object that is intended to be let through, for example, in children's motorcycles it will be a smaller diameter, or to grab the glasses of devices fixed for this purpose, such as a decorative carabiner type hook located on pants or sport jacket.
- the elastic band included in the state of the art is also used by the pilot to place the goggles in the face opening of the protective helmet, which is achieved by pulling both sides of the elastic band that are inserted on the front of the protective goggles, placing them in the coupling position in front of the opening of the protective helmet and taking care that the rest of the elastic band passes over the shell, so it is necessary to provide the front with gripping means that allow placing the front into the face opening of the hard hat in the most comfortable, clean and safe way possible.
- the placement or coupling of the protective glasses to the facial opening of the protective helmet can be done by holding the protective glasses frontally or on one of its sides depending on the tastes of each pilot, but always with the outer face of the front facing away from the helmet. the face opening of the helmet. For this reason, although a single outward elongation in the form of a tongue is sufficient to hold the goggles without touching sensitive parts of them, the front can be provided with additional gripping means, which are also located on the outer or front face.
- the front of the goggles comprises an elongation on the right outer side in the shape of a shoe horn with a circular hole at its distal end.
- the front of the goggles comprises one or more additional elongations in the upper part of the external face.
- these additional extensions are two in the form of two small antennas that allow the glasses to be grasped and attached to the facial opening of the helmet with one hand and without touching the screen.
- the proposed protective goggle front can fit a single, panoramic eyepiece, although it can also be made to house two independent eyepieces, like aviator glasses, without losing the essence of the proposed invention.
- the proposed protective glasses front can incorporate pivots for the hooking of additional devices and/or accessories to mitigate the impacts of mud and water on the screen, thus improving the existing protective glasses in the state of the art that place these devices on the screen, within the pilot's vision area.
- the proposed protective goggle front can be configured in two bodies mechanically joined by any means known in the art, so that the means for grasping remain in a body that will coincide with the outer part or face of the front while that the magnetic fixing means remain separately in the other body that will coincide with the inner part or face of the front.
- the useful life of the front is increased since, if any of the gripping means deteriorates due to a fall or a stone impact, it can be replaced and continue using the magnetic fixing means, which is the most expensive part to manufacture.
- the device for coupling the front of protective glasses to protective helmets consists of one or more bodies of reduced size to be located inside the protective helmets in an imperceptible way for the user, and in this way way to solve the problems derived from its location on the outside, such as breakage due to stone impacts, mud and falls.
- Each body comprises a preferably flat magnetic or magnetizable portion and a base portion that is configured to be adhered or attached to the protective helmet, so it can have any shape that allows its location in the area of the facial opening where the glasses are placed. protection during use.
- the device for coupling the front is presented as an element interrelated with the proposed protective goggle front, which once incorporated inside the protective helmet allows the temporary fixing of the front thanks to the magnetic or magnetizable material included in the preferably flat portion of the coupling device, which we will refer to as the magnetic portion, which is releasably or inseparably attached to the base portion, which is the portion that adheres to the protective helmet.
- the device is a means of magnetic fixation in its entirety, for example if it is understood as an integral element of a protective helmet that in that case would comprise magnetic means of fixation, so that to explain the object of The present invention refers indistinctly to magnetic fixing means and to magnetic or magnetizable portions, where both refer to the same thing; thus, for example, the magnetic or magnetizable portion that is joined to a base portion constitutes the magnetic fixing means of the proposed device, and the base portion that is joined to the magnetic or magnetizable portion constitutes the means of adhesion to the interior of the shell if configured as a snap-fit piece, or it may have attachment means such as high-strength glue if configured for use on helmets already on the market.
- the base portion is what joins the device object of the present invention to the protective helmet, and for this reason the description refers to these base bodies as means of fixing or adhering to the area of the facial opening of the helmet.
- protective helmets since their shape is configured to be releasably or inseparably attached to the inner lining of the helmet or to the inner area of the shell, for example as an elastomeric finish that covers the inner lining that absorbs impacts.
- both the proposed coupling device and the front comprise magnetic attachment means arranged to create the necessary magnetic attraction with the proposed front.
- the magnetic fixing means also comprise one or several magnetic or magnetizable portions, the number, shape, location and polarity of which will be correlated to the magnetic fixing means present on the front of the Proposed goggles, for example, will have two rectangular-shaped, flat-surfaced, magnetic portions located at both ends of the face opening of the helmet if the front comprises two rectangular-shaped, flat-surfaced, magnetizable portions located at both ends of the front.
- This is the only way to ensure that the magnetic fixing means are perfectly united when they are attracted, and they will also have to be located symmetrically so that deformities do not occur in the portions of the body to which they are attached.
- the magnetic fixing means of the device to achieve temporary fixation between the front and the device, it is required that the magnetic fixing means of the device, once adhered or fixed to the protection helmet, maintain an opposite polarity to that of the magnetic fixing means arranged on the front. , so that they are attracted to each other until they are perfectly united, because otherwise the device would repel the front and the protective glasses could not be fixed or coupled.
- the front or the device use magnetizable or ferromagnetic materials, in this case when the magnetic fixing means of the device contain magnetic portions or bodies, the magnetic fixing means of the front must contain magnetizable portions or bodies, and vice versa, so always create a magnetic attraction.
- the magnetic attraction thus allows the coupling and uncoupling of the front with one hand and without effort.
- the attraction between the bodies generated by magnetism is what allows the front of the goggles to be guided to its location effortlessly and almost autonomously and at the same time keep the goggles fixed or held in the corresponding part of the helmet's facial opening, perfectly centered to the millimeter. And at the same time, they allow you to detach the glasses by pulling the handle without having to use dexterity to remove the elastic band.
- the bodies that make up the coupling device have a portion with a preferably flat surface made of plastic material that serves as a support to house the magnet, preferably injected, or to house the magnetizable body, if applicable, and is the one that comes into contact with the magnetic fixing means included in the front of the proposed protective goggles, so this portion must be focused away from the facial opening of the helmet as a wall, to receive the magnetic or magnetizable portions located correlatively at the ends of the front of the proposed protective goggles, and with this it is achieved that the goggles are perfectly centered automatically without the need for the pilot to use dexterity to achieve a precise coupling.
- the rest of the coupling device is made up of a base portion that constitutes the fixing or adhesion means to the inside of the protective helmet, in a way that allows the magnetic fixing means of the device to be located in the area of the facial opening to receive the proposed front.
- This base portion can be individual when the device is made up of more than one body, or shared when the device is made up of a single body that has two or more magnetic or magnetizable parts, depending on the possibilities offered by each model of protective helmet. .
- the coupling device can be configured as two equal but autonomous bodies, where each one contains a magnetic portion attached to a base portion with a flat shape of a simple pendulum where the flat circle adheres to the inner face of the shell of the helmet and the line of the pendulum is between the central helmet padding and the side pads, leaving the magnetic or magnetizable portion exposed in the easy opening of the helmet on the sides of the helmet padding, or it can be configured as the rubber of profile that covers the edges of the shell of the protection helmet.
- the device can also take the form of an appendix to any of the elements that make up the interior of protective helmets, such as the inner shell, the inner lining, the padding or even the pads. sides.
- the base portion could be configured the same as the base plate of the padding of the side pads but with an extension or elongation that would be the link or connection with the portion magnetic or magnetizable, so that when the padding is inserted inside the helmet, the magnetized or magnetizable section or portion is at the height of the temple to receive the magnetic fixing means included in the proposed protective goggle front.
- the device can take the form of any integral element of the interior of the helmet that has a merely decorative, aesthetic or finishing function, to instead fulfill the function of a magnetic fixing means.
- the goggles only create a magnetic field with the device housed inside the protective helmet if they are in the correct position, and if the goggles do not placed in the correct position, for example upside down, the magnets arranged to attract them will repel the glasses instead of attracting them.
- the effect is achieved that one side of the forehead is not magnetically attracted to the wrong place on the opposite side of the helmet, so that the pilot can insert the forehead through one side of the helmet's face opening without danger of the magnet on one side is attracted prematurely before the front is fully positioned on the pilot's face.
- the polarity of the magnets is used as a measure to ensure the correct position of the goggles on the rider's face when he is using a protective helmet such as those used for motocross.
- this invention intends to replace the band elastic as a fixing means without changing the effect or feeling that the pilot has with it, that is, pulling both sides of the front of the goggles, and therefore the preferred embodiment uses a magnetic portion on each side instead of one centered.
- the plastic used to form the magnetic fixing means has a variable rigidity and elasticity that can be the same for the entire body or different for each part that makes it up, for example, in the front of protective glasses, the magnetic portions will have the same plastic used for form the inner face of the front since it acts as the base portion, while in the device the portion magnetic or magnetizable will have greater rigidity than the base portion if it is configured as the base plate of the central padding.
- plastic is an easily moldable material, and in fact it is the material used to make the front of protective glasses on the market and also of the different elements present inside the protective helmets, for example the bodies that make up the base of the padding inside the protective helmets or the covering of the edges of the shell made of fiber, among which there are those edges that delimit the facial opening of the protection helmet; and, secondly, because the plastic allows the injection of magnets, and thus magnetic bodies can be created in the shape of any of the plastic elements used inside protective helmets, while avoiding the use of magnets as adhered bodies that can be separated from their support due to a strong impact.
- the measurements of the bodies with injected magnet may vary depending on the magnetic force of the injected magnet.
- the magnets must be small and powerful, for example neodymium, covered with a protective material or not, for example with a thin layer of thermoplastic elastomer.
- the magnetic fixing means of both the front and the coupling device have a preferably flat surface is due to the fact that the cavities can house dirt that interferes with the magnetism, weakening it, and because they are also easier to clean; although it is possible to make them with relief as a male and female if you want to obtain a superior fixation, for example for other sports in which there are no dirty conditions.
- the coupling device can have its magnetic or magnetizable portions duplicated separately to fix the front to other surfaces where the goggles can rest, for example, on the protective foam of the motorcycle handlebar or on the sleeve of the ski jacket, for which these duplicated magnetic or magnetizable portions must have an adhesion means to adhere, for example a high-tack, water-resistant adhesive.
- the coupling device comprises at least one magnetic section or portion attached to the base portion by means of manually adjustable extension means to adjust the coupling of the proposed protective goggle front to the face opening of the protective helmet, so that the inner part of the front rests on the pilot's face without pressing excessively, since each pilot has his own facial physiognomy.
- the magnetic portion of the coupling device is releasably attached to the base portion to allow replacement, for example, to reduce the magnetic force of the device.
- the magnetized flat surfaces are attached to a base plate-shaped base portion of the side protective pads, releasably or inseparably, and have extension adjusters.
- the coupling device has at least two flat portions magnetized by injected magnet each attached to a "T" shaped base portion that engages in the edge of the internal lining (EPS) at the height of the temple, which may or may not include extension regulators.
- EPS internal lining
- the coupling device has at least two flat portions magnetized by an injected magnet, joined in a detachable or inseparable way to a flat portion in the form of a simple pendulum that adheres to the inner face of the shell at the height of the temple, which may or may not include extension regulators.
- the coupling device comprises at least two flat portions magnetized or magnetizable by injected magnet attached to the same base portion with a transverse "U" shape configured as a protective rubber profile to cover the edges or ends of the shell, with a self-adhesive interior to adhere like a clip to the ends of the shell that delimit the facial opening of the helmet, so that the flat magnetized or magnetizable portions are located on the upper part of the left and right sides of said opening.
- the coupling device comprises at least two bodies made of light and resistant material, for example plastic, each consisting of a flat rectangular portion magnetized by injected magnet that are releasably or inseparably attached to a base portion with a "U" shape like the rubber profile that covers the edges or ends of the shell at the height of the sides of the facial opening.
- the plastic body can be fixed to the helmet by means of a simple wide-headed screw such as those used to detachably join the visor to the helmet shell, or it can be configured as an inseparable part of the profile rubber that comes already. with the helmet from the factory or for its later replacement, or it can be superimposed on the plastic portion present in the protection helmet by means of a high resistance adhesive band.
- the bodies that contain the magnetized portions are detachably attached to the base portion, this allows them to be exchanged for other portions with a different thickness, so that the front always remains on the face of the user or pilot in a comfortable way, without excessive pressure. .
- the present invention offers protective goggles that allow the pilot to attach them to the facial opening of the protective helmet in the exact position with one hand, without dirtying the screen and in an extremely reduced time; Likewise, it allows you to remove them with just one as simply pulling them frontally towards the outside of the helmet, with the possibility of leaving them anchored in any of the motorcycle's handlebar grips. In muddy races, it allows riders to change goggles during the course of the event, drastically reducing the time it takes to remove goggles and put others on ready for use.
- the proposed invention is also applicable to other sports such as snowboarding, skiing, bmx, etc.
- the set of protective glasses front and device for coupling to the facial opening of protective helmets proposed solves each and every one of the aforementioned problems, with which more competitive protective glasses for protective helmets are obtained, because they allow its replacement in full competition for other equals in a few seconds; more durable, because they do without of the known fastening elements that are placed on the shell of the helmet exposed to breakage by impact, and because they dispense with the elastic band that is an easily damaged fastening element; more precise, because they attach to the helmet with total precision practically alone, bringing them closer to the face opening of the helmet with one hand; more efficient, because they are placed using one hand and removed only with two fingers of one hand; more comfortable, because they can be hung from the handlebars, or attached to the rider's clothing or other parts of the motorcycle, and they can be stored more loosely in their protective bag without the inconvenience of the bulky elastic band; more practical, because they allow the user to wear them attached to the helmet when they carry the helmet by hand before or after use; more modern, because when they are attached
